You have a CryptoListPresenter _presenter but you are never initializing it. You should either be doing that when you declare it or in your initState() (or another appropriate but called-before-you-need-it method).

One thing I find that helps is that if I know a member is functionally 'final', to actually set it to final as that way the analyzer complains that it hasn't been initialized.

EDIT:

I see diegoveloper beat me to answering this, and that the OP asked a follow up.

@Jake - it's hard for us to tell without knowing exactly what CryptoListPresenter is, but depending on what exactly CryptoListPresenter actually is, generally you'd do final CryptoListPresenter _presenter = new CryptoListPresenter(...);, or

CryptoListPresenter _presenter;

@override
void initState() {
  _presenter = new CryptoListPresenter(...);
}

I know I'm a little late to the party, but I did want to throw some interjections. (I would have commented but not enough reputation points yet, so, here's a full answer).

This requires the latest version of VS Code, Azure Repo Extention, and Git to be installed.

Anyone looking to use the new VS Code (or using the preview like myself), when you go to the Settings (Still File -> Preferences -> Settings or CTRL+, ) you'll be looking under User Settings -> Extensions -> Azure Repos.

Then under Tfvc: Location you can paste the location of the executable.

For 2017 it'll be

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

Or for 2019 (Preview)

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

After adding the location, I closed my VS Code (not sure if this was needed) and went my git repo to copy the git URL.

After that, went back into VS Code went to the Command Palette (View -> Command Palette or CTRL+Shift+P) typed Git: Clone pasted my repo:

Selected the location for the repo to be stored. Next was an error that popped up. I proceeded to follow this video which walked me through clicking on the Team button with the exclamation mark on the bottom of your VS Code Screen

Then chose the new method of authentication

Copy by using CTRL+C and then press enter. Your browser will launch a page where you'll enter the code you copied (CTRL+V).

Click Continue

Log in with your Microsoft Credentials and you should see a change on the bottom bar of VS Code.

Cheers!

For identifying NaN values use boolean indexing:

print(df[df['x'].isnull()])

Then for removing all non-numeric values use to_numeric with parameter errors='coerce' - to replace non-numeric values to NaNs:

df['x'] = pd.to_numeric(df['x'], errors='coerce')

And for remove all rows with NaNs in column x use dropna:

df = df.dropna(subset=['x'])

Last convert values to ints:

df['x'] = df['x'].astype(int)

For me it also was problem with path, but I had percentage sign in the root folder.

After I replaced %20 with space, it started to work :)

This module is added automatically when you run ionic command. However it's not necessery. So an alternative solution is to remove add-event.module.ts from the project.

Here's my attempt. Excuse the fluff, I was feeling extra creative.

My method is a parent div with fixed dimensions. The rest is just fitting the content inside that div accordingly.

This will rescale the images regardless of the aspect ratio. There will be no hard cropping either.

I had this problem when I added a css file to the same folder as the component file.

My import statement was:

import MyComponent from '../MyComponent'

which was fine when there was only a single file, MyComponent.jsx. (I saw this format in an example and gave it a try, then forgot I'd done it)

When I added MyComponent.scss to the same folder, the import then failed. Maybe JavaScript loaded the .scss file instead, and so there was no error.

My conclusion: always specify the file extension even if there is only one file, in case you add another one later.

Trying on a different browser(chrome) worked for me and clearing cache on firefox cleared the issue.

(PS: Not add the hosting URIs to Authorized JavaScript origins in API credentials would give you Error:redirect_uri_mismatch)

this is the solution to close menu when click on anchor then apply this line in list item

     data-target="#sidenav-collapse-main" data-toggle="collapse"

the real example that work for me is below

      <li class="nav-item" data-target="#sidenav-collapse-main" data- 
      toggle="collapse" >
      <a class="nav-link" routerLinkActive="active" routerLink="/admin/users">
        <i class="ni ni-single-02  text-orange"></i> Users
      </a>
      </li>

If you want the time out as well as the date you want Date.toLocaleString().

This was direct from my console:

> new Date().toLocaleString()
> "11/10/2016, 11:49:36 AM"

You can then input locale strings and format string to get the precise output you want.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString

You were getting this error because you followed the poorly-written directions on the Heroes tutorial. I ran into the same thing.

Specifically, under the heading Display hero names in a template, it states:

To display the hero names in an unordered list, insert the following chunk of HTML below the title and above the hero details.

followed by this code block:

<h2>My Heroes</h2>
<ul class="heroes">
  <li>
    <!-- each hero goes here -->
  </li>
</ul>

It does not instruct you to replace the previous detail code, and it should. This is why we are left with:

<h2>{{hero.name}} details!</h2>

outside of our *ngFor.

However, if you scroll further down the page, you will encounter the following:

The template for displaying heroes should look like this:

<h2>My Heroes</h2>
<ul class="heroes">
  <li *ngFor="let hero of heroes">
    <span class="badge">{{hero.id}}</span> {{hero.name}}
  </li>
</ul>

Note the absence of the detail elements from previous efforts.

An error like this by the author can result in quite a wild goose-chase. Hopefully, this post helps others avoid that.

In Centos

 sudo yum install php-xml

and restart apache

sudo service httpd restart

You can do it like

<button v-on:click="Function1(); Function2();"></button>

OR

<button @click="Function1(); Function2();"></button>

I fixed this by doing the following:

1. going into GenyMotion settings -> ADB tab,
2. instead of Use Genymotion Android tools (default), I chose Use custom Android SDK Tools and then browsed to my installed SDK.

Other configurable Spark option relating to jars and classpath, in case of yarn as deploy mode are as follows
From the spark documentation,

spark.yarn.jars

List of libraries containing Spark code to distribute to YARN containers. By default, Spark on YARN will use Spark jars installed locally, but the Spark jars can also be in a world-readable location on HDFS. This allows YARN to cache it on nodes so that it doesn't need to be distributed each time an application runs. To point to jars on HDFS, for example, set this configuration to hdfs:///some/path. Globs are allowed.

spark.yarn.archive

An archive containing needed Spark jars for distribution to the YARN cache. If set, this configuration replaces spark.yarn.jars and the archive is used in all the application's containers. The archive should contain jar files in its root directory. Like with the previous option, the archive can also be hosted on HDFS to speed up file distribution.

Users can configure this parameter to specify their jars, which inturn gets included in Spark driver's classpath.

Just like that nice warning you got, you are trying to do something that is an Anti-Pattern in React. This is a no-no. React is intended to have an unmount happen from a parent to child relationship. Now if you want a child to unmount itself, you can simulate this with a state change in the parent that is triggered by the child. let me show you in code.

class Child extends React.Component {
    constructor(){}
    dismiss() {
        this.props.unmountMe();
    } 
    render(){
        // code
    }
}

class Parent ...
    constructor(){
        super(props)
        this.state = {renderChild: true};
        this.handleChildUnmount = this.handleChildUnmount.bind(this);
    }
    handleChildUnmount(){
        this.setState({renderChild: false});
    }
    render(){
        // code
        {this.state.renderChild ? <Child unmountMe={this.handleChildUnmount} /> : null}
    }

}

this is a very simple example. but you can see a rough way to pass through to the parent an action

That being said you should probably be going through the store (dispatch action) to allow your store to contain the correct data when it goes to render

I've done error/status messages for two separate applications, both went through the store. It's the preferred method... If you'd like I can post some code as to how to do that.

EDIT: Here is how I set up a notification system using React/Redux/Typescript

Few things to note first. this is in typescript so you would need to remove the type declarations :)

I am using the npm packages lodash for operations, and classnames (cx alias) for inline classname assignment.

The beauty of this setup is I use a unique identifier for each notification when the action creates it. (e.g. notify_id). This unique ID is a Symbol(). This way if you want to remove any notification at any point in time you can because you know which one to remove. This notification system will let you stack as many as you want and they will go away when the animation is completed. I am hooking into the animation event and when it finishes I trigger some code to remove the notification. I also set up a fallback timeout to remove the notification just in case the animation callback doesn't fire.

notification-actions.ts

import { USER_SYSTEM_NOTIFICATION } from '../constants/action-types';

interface IDispatchType {
    type: string;
    payload?: any;
    remove?: Symbol;
}

export const notifySuccess = (message: any, duration?: number) => {
    return (dispatch: Function) => {
        dispatch({ type: USER_SYSTEM_NOTIFICATION, payload: { isSuccess: true, message, notify_id: Symbol(), duration } } as IDispatchType);
    };
};

export const notifyFailure = (message: any, duration?: number) => {
    return (dispatch: Function) => {
        dispatch({ type: USER_SYSTEM_NOTIFICATION, payload: { isSuccess: false, message, notify_id: Symbol(), duration } } as IDispatchType);
    };
};

export const clearNotification = (notifyId: Symbol) => {
    return (dispatch: Function) => {
        dispatch({ type: USER_SYSTEM_NOTIFICATION, remove: notifyId } as IDispatchType);
    };
};

notification-reducer.ts

const defaultState = {
    userNotifications: []
};

export default (state: ISystemNotificationReducer = defaultState, action: IDispatchType) => {
    switch (action.type) {
        case USER_SYSTEM_NOTIFICATION:
            const list: ISystemNotification[] = _.clone(state.userNotifications) || [];
            if (_.has(action, 'remove')) {
                const key = parseInt(_.findKey(list, (n: ISystemNotification) => n.notify_id === action.remove));
                if (key) {
                    // mutate list and remove the specified item
                    list.splice(key, 1);
                }
            } else {
                list.push(action.payload);
            }
            return _.assign({}, state, { userNotifications: list });
    }
    return state;
};

app.tsx

in the base render for your application you would render the notifications

render() {
    const { systemNotifications } = this.props;
    return (
        <div>
            <AppHeader />
            <div className="user-notify-wrap">
                { _.get(systemNotifications, 'userNotifications') && Boolean(_.get(systemNotifications, 'userNotifications.length'))
                    ? _.reverse(_.map(_.get(systemNotifications, 'userNotifications', []), (n, i) => <UserNotification key={i} data={n} clearNotification={this.props.actions.clearNotification} />))
                    : null
                }
            </div>
            <div className="content">
                {this.props.children}
            </div>
        </div>
    );
}

user-notification.tsx

user notification class

/*
    Simple notification class.

    Usage:
        <SomeComponent notifySuccess={this.props.notifySuccess} notifyFailure={this.props.notifyFailure} />
        these two functions are actions and should be props when the component is connect()ed

    call it with either a string or components. optional param of how long to display it (defaults to 5 seconds)
        this.props.notifySuccess('it Works!!!', 2);

        this.props.notifyFailure(<div>You dun goofed</div>);

*/

interface IUserNotifyProps {
    data: any;
    clearNotification(notifyID: symbol): any;
}

export default class UserNotify extends React.Component<IUserNotifyProps, {}> {
    public notifyRef = null;
    private timeout = null;

    componentDidMount() {
        const duration: number = _.get(this.props, 'data.duration', '');
       
        this.notifyRef.style.animationDuration = duration ? `${duration}s` : '5s';

        
        // fallback incase the animation event doesn't fire
        const timeoutDuration = (duration * 1000) + 500;
        this.timeout = setTimeout(() => {

            this.props.clearNotification(_.get(this.props, 'data.notify_id') as symbol);
        }
    }
    handleCloseClick = (e) => {
        e.preventDefault();

        return (
            <div ref={this.assignNotifyRef} className={cx('user-notification fade-in-out', {success: data.isSuccess, failure: !data.isSuccess})}>
                {!_.isString(data.message) ? data.message : <h3>{data.message}</h3>}
                <div className="close-message" onClick={this.handleCloseClick}>+</div>
            </div>
        );
    }
}

There's simpler solution for that - set fixed height of card elements - header and body. This way, we can set resposive layout with standard boostrap column grid.

Here is my example: http://codeply.com/go/RHDawRSBol

 <div class="card-deck text-center">
    <div class="col-sm-6 col-md-4 col-lg-3">
        <div class="card mb-4">
            <img class="card-img-top img-fluid" src="//placehold.it/500x280" alt="Card image cap">
            <div class="card-body" style="height: 20rem">
                <h4 class="card-title">1 Card title</h4>
                <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
                <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
            </div>
        </div>

DO NOT USE SASS OR ANGULAR's EMBEDDED CSS SYSTEM!!

I cannot stress this enough. The people at Angular did not understand basic cascading style sheet systems as when you use both these technologies - as with this angular.json setting - the compiler stuffs all your CSS into Javascript modules then spits them out into the head of your HTML pages as embedded CSS that breaks and confuses cascade orders and disables native CSS import cascades.

For that reason, I recommend you REMOVE ALL STYLE REFERENCES FROM "ANGULAR.JSON", then add them back into your "index.html" manually as links like this:

<link href="styles/styles.css" rel="stylesheet" />

You now have a fully functioning, cascading CSS system that's fully cached in your browser over many refreshes without ECMAScripted circus tricks, saving huge amounts of bandwidth, increasing CSS overall management in static files, and full control over your cascade order minus the clunky embedded CSS injected into the head of all your web pages which Angular tries to do.

SASS isn't even necessary when you understand how to manage cascades in basic CSS files. Large sites with complex CSS can be very simple to manage for those that bother to learn cascade orders using a handful of linked CSS files.

I've built a fairly simple, reusable and functional Angular2 autocomplete component based on some of the ideas in this answer/other tutorials around on this subject and others. It's by no means comprehensive but may be helpful if you decide to build your own.

The component:

import { Component, Input, Output, OnInit, ContentChild, EventEmitter, HostListener } from '@angular/core';
import { Observable } from "rxjs/Observable";
import { AutoCompleteRefDirective } from "./autocomplete.directive";

@Component({
    selector: 'autocomplete',
    template: `
<ng-content></ng-content>
<div class="autocomplete-wrapper" (click)="clickedInside($event)">
    <div class="list-group autocomplete" *ngIf="results">
        <a [routerLink]="" class="list-group-item" (click)="selectResult(result)" *ngFor="let result of results; let i = index" [innerHTML]="dataMapping(result) | highlight: query" [ngClass]="{'active': i == selectedIndex}"></a>
    </div>
</div>
    `,
    styleUrls: ['./autocomplete.component.css']
})
export class AutoCompleteComponent implements OnInit {

    @ContentChild(AutoCompleteRefDirective)
    public input: AutoCompleteRefDirective;

    @Input() data: (searchTerm: string) => Observable<any[]>;
    @Input() dataMapping: (obj: any) => string;
    @Output() onChange = new EventEmitter<any>();

    @HostListener('document:click', ['$event'])
    clickedOutside($event: any): void {
        this.clearResults();
    }

    public results: any[];
    public query: string;
    public selectedIndex: number = 0;
    private searchCounter: number = 0;

    ngOnInit(): void {

                }
            });

        this.input.up
            .subscribe(() => {
                if (this.results && this.selectedIndex > 0) this.selectedIndex--;
            });

        this.input.down

    selectResult(result: any): void {
        this.onChange.emit(result);
        this.clearResults();
    }

    clickedInside($event: any): void {
        $event.preventDefault();
        $event.stopPropagation();
    }

    private clearResults(): void {
        this.results = [];
        this.selectedIndex = 0;
        this.searchCounter = 0;
        this.input.hasResults = false;
    }
}

The component CSS:

.autocomplete-wrapper {
    position: relative;
}

.autocomplete {
    position: absolute;
    z-index: 100;
    width: 100%;
}

The directive:

import { Directive, Input, Output, HostListener, EventEmitter } from '@angular/core';

@Directive({
    selector: '[autocompleteRef]'
})
export class AutoCompleteRefDirective {
    @Input() hasResults: boolean = false;
    @Output() change = new EventEmitter<string>();
    @Output() cancel = new EventEmitter();
    @Output() select = new EventEmitter();
    @Output() up = new EventEmitter();
    @Output() down = new EventEmitter();

    @HostListener('input', ['$event'])
    oninput(event: any) {
        this.change.emit(event.target.value);
    }

    @HostListener('keydown', ['$event'])
    onkeydown(event: any)
    {
        switch (event.keyCode) {
            case 27:
                this.cancel.emit();
                return false;
            case 13:
                var hasResults = this.hasResults;
                this.select.emit();
                return !hasResults;
            case 38:
                this.up.emit();
                return false;
            case 40:
                this.down.emit();
                return false;
            default:
        }
    }
}

The highlight pipe:

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
    name: 'highlight'
})

export class HighlightPipe implements PipeTransform {
    transform(value: string, args: any): any {
        var re = new RegExp(args, 'gi');

        return value.replace(re, function (match) {
            return "<strong>" + match + "</strong>";
        })

    }
}

The implementation:

import { Component } from '@angular/core';
import { Observable } from "rxjs/Observable";
import { Subscriber } from "rxjs/Subscriber";

@Component({
    selector: 'home',
    template: `
<autocomplete [data]="getData" [dataMapping]="dataMapping" (onChange)="change($event)">
    <input type="text" class="form-control" name="AutoComplete" placeholder="Search..." autocomplete="off" autocompleteRef />
</autocomplete>
    `
})
export class HomeComponent {

    getData = (query: string) => this.search(query);

    // The dataMapping property controls the mapping of an object returned via getData.
    // to a string that can be displayed to the use as an option to select.
    dataMapping = (obj: any) => obj;

    // This function is called any time a change is made in the autocomplete.
    // When the text is changed manually, no object is passed.
    // When a selection is made the object is passed.
    change(obj: any): void {
        if (obj) {
            // You can do pretty much anything here as the entire object is passed if it's been selected.
            // Navigate to another page, update a model etc.
            alert(obj);
        }
    }

    private searchData = ['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten'];

    // This function mimics an Observable http service call.
    // In reality it's probably calling your API, but today it's looking at mock static data.
    private search(query: string): Observable<any>
    {
        return new Observable<any>((subscriber: Subscriber<any>) => subscriber
            .next())
            .map(o => this.searchData.filter(d => d.indexOf(query) > -1));
    }
}

Cannot say about the "official nomenclature" - infact I wonder whose word will be "official" anyway - but here's how they can be called:

• Horizontal stripes : Hamburger menu / icon / button -> -> as per wiki. A name like "sandwich button" would also have been good IMO :(
• Vertical ellipsis : Dango menu / icon / button -> -> credits to this guy. This one I like thanks to the song from the super duper anime Clannad

I would say that it depends on what you want to do.

If your dropdown is a component for a form that manages a state, I would leverage the two-way binding of Angular2. For this, I would use two attributes: an input one to get the associated object and an output one to notify when the state changes.

Here is a sample:

export class DropdownValue {
  value:string;
  label:string;

  constructor(value:string,label:string) {
    this.value = value;
    this.label = label;
  }
}

@Component({
  selector: 'dropdown',
  template: `
    <ul>
      <li *ngFor="let value of values" (click)="select(value.value)">{{value.label}}</li>
    </ul>
  `
})
export class DropdownComponent {
  @Input()
  values: DropdownValue[];

  @Input()
  value: string[];

  @Output()
  valueChange: EventEmitter;

  constructor(private elementRef:ElementRef) {
    this.valueChange = new EventEmitter();
  }

  select(value) {
    this.valueChange.emit(value);
  }
}

This allows you to use it this way:

<dropdown [values]="dropdownValues" [(value)]="value"></dropdown>

You can build your dropdown within the component, apply styles and manage selections internally.

Edit

You can notice that you can either simply leverage a custom event in your component to trigger the selection of a dropdown. So the component would now be something like this:

export class DropdownValue {
  value:string;
  label:string;

  constructor(value:string,label:string) {
    this.value = value;
    this.label = label;
  }
}

@Component({
  selector: 'dropdown',
  template: `
    <ul>
      <li *ngFor="let value of values" (click)="selectItem(value.value)">{{value.label}}</li>
    </ul>
  `
})
export class DropdownComponent {
  @Input()
  values: DropdownValue[];

  @Output()
  select: EventEmitter;

  constructor() {
    this.select = new EventEmitter();
  }

  selectItem(value) {
    this.select.emit(value);
  }
}

Then you can use the component like this:

<dropdown [values]="dropdownValues" (select)="action($event.value)"></dropdown>

Notice that the action method is the one of the parent component (not the dropdown one).

Add this code structure to your page code

<?php
echo '<label>Admission Year:</label><br><select name="admission_year" data-component="date">';
for($year=1900; $year<=date('Y'); $year++){
echo '<option value="'.$year.'">'.$year.'</option>';
}
?>

It works perfectly and can be reverse engineered

<?php
echo '<label>Admission Year:</label><br><select name="admission_year" data-component="date">';
for($year=date('Y'); $year>=1900; $year++){
echo '<option value="'.$year.'">'.$year.'</option>';
}
?>

With this you are good to go.

i tried to train unet on voc data set but because of huge image size, memory finishes. i tried all the above tips, even tried with batch size==1, yet to no improvement. sometimes TensorFlow version also causes the memory issues. try by using

pip install tensorflow-gpu==1.8.0

Install @babel/plugin-proposal-export-default-from via:

yarn add -D @babel/plugin-proposal-export-default-from

In your .babelrc.json or any of the Configuration File Types

module.exports = {
  //...
  plugins: [
     '@babel/plugin-proposal-export-default-from'
  ]
  //...
}

Now you can export directly from a file-path:

export Foo from './components/Foo'
export Bar from './components/Bar'

Good Luck...

1. Install ts-node node module globally.
2. Create node runtime configuration (for IDE) or use node in command line to run below file js file (The path is for windows, but you can do it for linux as well) ~\AppData\Roaming\npm\node_modules\ts-node\dist\bin.js
3. Give your ts file path as a command line argument.
4. Run Or Debug as you like.

Given that ECMA is a 'class-free' language, implementing classical composition doesn't - in my eyes - make a lot of sense. The danger is that, in so doing, you are effectively attempting to re-engineer the language (and, if one feels strongly about that, there are excellent holistic solutions such as the aforementioned TypeScript that mitigate reinventing the wheel)

Now that isn't to say that composition is out of the question however in Plain Old JS. I researched this at length some time ago. The strongest candidate I have seen for handling composition within the object prototypal paradigm is stampit, which I now use across a wide range of projects. And, importantly, it adheres to a well articulated specification.

Accepting Optional as parameters causes unnecessary wrapping at caller level.

For example in the case of:

public int calculateSomething(Optional<String> p1, Optional<BigDecimal> p2 {}

Suppose you have two not-null strings (ie. returned from some other method):

String p1 = "p1"; 
String p2 = "p2";

You're forced to wrap them in Optional even if you know they are not Empty.

This get even worse when you have to compose with other "mappable" structures, ie. Eithers:

Either<Error, String> value = compute().right().map((s) -> calculateSomething(
< here you have to wrap the parameter in a Optional even if you know it's a 
  string >));

ref:

methods shouldn't expect Option as parameters, this is almost always a code smell that indicated a leakage of control flow from the caller to the callee, it should be responsibility of the caller to check the content of an Option

ref. https://github.com/teamdigitale/digital-citizenship-functions/pull/148#discussion_r170862749

Part One - Polyfill

For browsers that haven't implemented it, a polyfill for array.find. Courtesy of MDN.

if (!Array.prototype.find) {
  Array.prototype.find = function(predicate) {
    if (this == null) {
      throw new TypeError('Array.prototype.find called on null or undefined');
    }
    if (typeof predicate !== 'function') {
      throw new TypeError('predicate must be a function');
    }
    var list = Object(this);
    var length = list.length >>> 0;
    var thisArg = arguments[1];
    var value;

    for (var i = 0; i < length; i++) {
      value = list[i];
      if (predicate.call(thisArg, value, i, list)) {
        return value;
      }
    }
    return undefined;
  };
}

Part Two - Interface

You need to extend the open Array interface to include the find method.

interface Array<T> {
    find(predicate: (search: T) => boolean) : T;
}

When this arrives in TypeScript, you'll get a warning from the compiler that will remind you to delete this.

Part Three - Use it

The variable x will have the expected type... { id: number }

var x = [{ "id": 1 }, { "id": -2 }, { "id": 3 }].find(myObj => myObj.id < 0);

for me, I was adding spring-web instead of the spring-boot-starter-web into my pom.xml

when i replace it from spring-web to spring-boot-starter-web, all maping is shown in the console log.

You can do this easily in vanilla JS:

Using find

const savedViews = [{"description":"object1","id":1},{"description":"object2","id":2},{"description":"object3","id":3},{"description":"object4","id":4}];_x000D_
_x000D_
const view = 'object2';_x000D_
_x000D_
const delete_id = savedViews.find(obj => {_x000D_
  return obj.description === view;_x000D_
}).id;_x000D_
_x000D_
console.log(delete_id);

Using filter (original answer)

const savedViews = [{"description":"object1","id":1},{"description":"object2","id":2},{"description":"object3","id":3},{"description":"object4","id":4}];_x000D_
_x000D_
const view = 'object2';_x000D_
_x000D_
const delete_id = savedViews.filter(function (el) {_x000D_
  return el.description === view;_x000D_
})[0].id;_x000D_
_x000D_
console.log(delete_id);

The document suggests that it takes the @color/accent by default. But we can override it on code by using

fab.setBackgroundTintList(ColorStateList)

Also remember,

The minimum API version to use this library is 15 so you need to update it! if you dont want to do it then you need to define a custom drawable and decorate it!

Unfortunately you can't animate the display property. For a full list of what you can animate, try this CSS animation list by w3 Schools.

If you want to retain it's visual position on the page, you should try animating either it's height (which will still affect the position of other elements), or opacity (how transparent it is). You could even try animating the z-index, which is the position on the z axis (depth), by putting an element over the top of it, and then rearranging what's on top. However, I'd suggest using opacity, as it retains the vertical space where the element is.

I've updated the fiddle to show an example.

Good luck!

'default' => env('DB_CONNECTION', 'mysql'),

add this in your code

Swift 5 Enjoy

tablev.rowHeight = 100
tablev.estimatedRowHeight = UITableView.automaticDimension


func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = self.tablev.dequeueReusableCell(withIdentifier: "ConferenceRoomsCell") as! ConferenceRoomsCell
    cell.lblRoomName.numberOfLines = 0
    cell.lblRoomName.lineBreakMode = .byWordWrapping
    cell.lblRoomName.text = arrNameOfRooms[indexPath.row]
    cell.lblRoomName.sizeToFit()
    return cell
}

You could search for the corresponding key or you could "invert" the dictionary, but considering how you use it, it would be best if you just iterated over key/value pairs in the first place, which you can do with items(). Then you have both directly in variables and don't need a lookup at all:

for key, value in PIX0.items():
    NUM = input("What is the Resolution of %s?"  % key)
    if NUM == value:

You can of course use that both ways then.

Or if you don't actually need the dictionary for something else, you could ditch the dictionary and have an ordinary list of pairs.

First of all, goto extensions (Ctrl + Shift + X) and install 2 extensions:

1. Code Runner
2. C/C++

Then, then reload the VS Code and select a play button on the top of the right corner your program runs in the output terminal. You can see output by Ctrl + Alt + N. To change other features goto user setting.

SHIFT+CTRL+B should work

However sometimes an issue can happen in a locked down non-adminstrator evironment:

If you open an existing C# application from the folder you should have a .sln (solution file) etc..

Commonly you can get these message in VS Code

TL;DR

The object returned by range() is actually a range object. This object implements the iterator interface so you can iterate over its values sequentially, just like a generator, list, or tuple.

But it also implements the __contains__ interface which is actually what gets called when an object appears on the right hand side of the in operator. The __contains__() method returns a bool of whether or not the item on the left-hand-side of the in is in the object. Since range objects know their bounds and stride, this is very easy to implement in O(1).

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

just parse as an array:

Review[] reviews = new Gson().fromJson(jsonString, Review[].class);

then if you need you can also create a list in this way:

List<Review> asList = Arrays.asList(reviews);

P.S. your json string should be look like this:

[
    {
        "reviewerID": "A2SUAM1J3GNN3B1",
        "asin": "0000013714",
        "reviewerName": "J. McDonald",
        "helpful": [2, 3],
        "reviewText": "I bought this for my husband who plays the piano.",
        "overall": 5.0,
        "summary": "Heavenly Highway Hymns",
        "unixReviewTime": 1252800000,
        "reviewTime": "09 13, 2009"
    },
    {
        "reviewerID": "A2SUAM1J3GNN3B2",
        "asin": "0000013714",
        "reviewerName": "J. McDonald",

If you use %pylab inline you can (on a new line) insert the following command:

%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)

This will set all figures in your document (unless otherwise specified) to be of the size (10, 6), where the first entry is the width and the second is the height.

See this SO post for more details. https://stackoverflow.com/a/17231361/1419668

Or use pattern matching

Basic docker-compose.yml with extra hosts:

version: '3'
services:
api:
    build: .
    ports:
        - "5003:5003"
    extra_hosts:
        - "your-host.name.com:162.242.195.82" #host and ip
        - "your-host--1.name.com your-host--2.name.com:50.31.209.229" #multiple hostnames with same ip
        

The content in the /etc/hosts file in the created container:

162.242.195.82  your-host.name.com
50.31.209.229   your-host--1.name.com your-host--2.name.com

You can check the /etc/hosts file with the following commands:

$ docker-compose -f path/to/file/docker-compose.yml run api bash  # 'api' is service name
#then inside container bash

As long as you are okay with writing a separate .h/.cpp pair for each queryable enum, this solution works with nearly the same syntax and capabilities as a regular c++ enum:

// MyEnum.h
#include <EnumTraits.h>
#ifndef ENUM_INCLUDE_MULTI
#pragma once
#end if

enum MyEnum : int ETRAITS
{
    EDECL(AAA) = -8,
    EDECL(BBB) = '8',
    EDECL(CCC) = AAA + BBB
};

The .cpp file is 3 lines of boilerplate:

// MyEnum.cpp
#define ENUM_DEFINE MyEnum
#define ENUM_INCLUDE <MyEnum.h>
#include <EnumTraits.inl>

Example usage:

for (MyEnum value : EnumTraits<MyEnum>::GetValues())
    std::cout << EnumTraits<MyEnum>::GetName(value) << std::endl;

Code

This solution requires 2 source files:

// EnumTraits.h
#pragma once
#include <string>
#include <unordered_map>
#include <vector>

#define ETRAITS
#define EDECL(x) x

template <class ENUM>
class EnumTraits
{
public:
    static const std::vector<ENUM>& GetValues()
    {
        return values;
    }

    static ENUM GetValue(const char* name)
    {
        auto match = valueMap.find(name);
        return (match == valueMap.end() ? ENUM() : match->second);
    }

    static const char* GetName(ENUM value)
    {
        auto match = nameMap.find(value);
        return (match == nameMap.end() ? nullptr : match->second);
    }

public:
    EnumTraits() = delete;

    using vector_type = std::vector<ENUM>;
    using name_map_type = std::unordered_map<ENUM, const char*>;
    using value_map_type = std::unordered_map<std::string, ENUM>;

private:
    static const vector_type values;
    static const name_map_type nameMap;
    static const value_map_type valueMap;
};

struct EnumInitGuard{ constexpr const EnumInitGuard& operator=(int) const { return *this; } };
template <class T> constexpr T& operator<<=(T&& x, const EnumInitGuard&) { return x; }

...and

// EnumTraits.inl
#define ENUM_INCLUDE_MULTI

#include ENUM_INCLUDE
#undef ETRAITS
#undef EDECL

using EnumType = ENUM_DEFINE;
using TraitsType = EnumTraits<EnumType>;
using VectorType = typename TraitsType::vector_type;

using ValueMapType = typename TraitsType::value_map_type;
using NamePairType = typename NameMapType::value_type;
using ValuePairType = typename ValueMapType::value_type;

#define ETRAITS ; const VectorType TraitsType::values
#define EDECL(x) EnumType::x <<= EnumInitGuard()
#include ENUM_INCLUDE
#undef ETRAITS
#undef EDECL

#define ETRAITS ; const NameMapType TraitsType::nameMap

This implementation exploits the fact that the braced list of elements of an enum definition can also be used as a braced initializer list for class member initialization.

When ETRAITS is evaluated in the context of EnumTraits.inl, it expands out to a static member definition for the EnumTraits<> class.

The EDECL macro transforms each enum member into initializer list values which subsequently get passed into the member constructor in order to populate the enum info.

The EnumInitGuard class is designed to consume the enum initializer values and then collapse - leaving a pure list of enum data.

Benefits

• c++-like syntax
• Works identically for both enum and enum class (*almost)
• Works for enum types with any numeric underlying type
• Works for enum types with automatic, explicit, and fragmented initializer values
• Works for mass renaming (intellisense linking preserved)
• Only 5 preprocessor symbols (3 global)

* In contrast to enums, initializers in enum class types that reference other values from the same enum must have those values fully qualified

Disbenefits

• Requires a separate .h/.cpp pair for each queryable enum
• Depends on convoluted macro and include magic
• Minor syntax errors explode into much larger errors
• Defining class or namespace scoped enums is nontrivial
• No compile time initialization

Comments

Intellisense will complain a bit about private member access when opening up EnumTraits.inl, but since the expanded macros are actually defining class members, that isn't actually a problem.

The #ifndef ENUM_INCLUDE_MULTI block at the top of the header file is a minor annoyance that could probably be shrunken down into a macro or something, but it's small enough to live with at its current size.

Declaring a namespace scoped enum requires that the enum first be forward declared inside its namespace scope, then defined in the global namespace. Additionally, any enum initializers using values of the same enum must have those values fully qualified.

namespace ns { enum MyEnum : int; }
enum ns::MyEnum : int ETRAITS
{
    EDECL(AAA) = -8,
    EDECL(BBB) = '8',
    EDECL(CCC) = ns::MyEnum::AAA + ns::MyEnum::BBB
}

as per @cyberbikepunk answer pycharm supports Anaconda since pycharm5!

Have a look how easy is to add an environment:

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

Using docker links, you can link the upstream container to the nginx container. An added feature is that docker manages the host file, which means you'll be able to refer to the linked container using a name rather than the potentially random ip.

Simply translating the "old for loop way" into streams:

private Map<String, String> mapConfig(Map<String, Integer> input, String prefix) {
    int subLength = prefix.length();
    return input.entrySet().stream()
            .collect(Collectors.toMap(
                   entry -> entry.getKey().substring(subLength), 
                   entry -> AttributeType.GetByName(entry.getValue())));
}

IE can set username and password proxies, so maybe setting it there and import does work

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d name:port
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyUser /t REG_SZ /d username
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyPass /t REG_SZ /d password
netsh winhttp import proxy source=ie

I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:

The things to do are:

• Create a new web application
• Install the following NuGet packages:
  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security.OAuth
  • Microsoft.AspNet.Identity.Owin
• Add a OWIN startup class

Then create a HTML and a JavaScript (index.js) file with these contents:

var loginData = 'grant_type=password&[email protected]&password=test123';

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
    if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
        alert(xmlhttp.responseText);
    }
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    <script type="text/javascript" src="index.js"></script>
</body>
</html>

The OWIN startup class should have this content:

using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;

[assembly: OwinStartup(typeof(Startup))]

namespace OAuth20
{
    public class Startup
    {
        public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }

        public void Configuration(IAppBuilder app)
        {
            OAuthOptions = new OAuthAuthorizationServerOptions()
            {
                TokenEndpointPath = new PathString("/token"),
                Provider = new OAuthAuthorizationServerProvider()
                {
                    OnValidateClientAuthentication = async (context) =>
                    {
                        context.Validated();
                    },
                    OnGrantResourceOwnerCredentials = async (context) =>
                    {
                        if (context.UserName == "[email protected]" && context.Password == "test123")
                        {
                            ClaimsIdentity oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
                            context.Validated(oAuthIdentity);
                        }
                    }
                },
                AllowInsecureHttp = true,
                AccessTokenExpireTimeSpan = TimeSpan.FromDays(1)
            };

            app.UseOAuthBearerTokens(OAuthOptions);
        }
    }
}

Run your project. The token should be displayed in the pop-up.

One of the ways to do it is to drive this through your CI/CD systems. Once your parent image is built, have something that scans your git repos for images using that parent. If found, you'd then send a pull request to bump to new versions of the image. The pull request, if all tests pass, would be merged and you'd have a new child image based on updated parent. An example of a tool that takes this approach can be found here: https://engineering.salesforce.com/open-sourcing-dockerfile-image-update-6400121c1a75 .

If you don't control your parent image, as would be the case if you are depending on the official ubuntu image, you can write some tooling that detects changes in the parent image tag or checksum(not the same thing, tags are mutable) and invoke children image builds accordingly.

Here is a simplified version of the 2-step approach using build and commit, without shell scripts. It involves:

1. Building the image partially, without volumes
2. Running a container with volumes, making changes, then committing the result, replacing the original image name.

With relatively minor changes the additional step adds only a few seconds to the build time.

Basically:

docker build -t image-name . # your normal docker build

# Now run a command in a throwaway container that uses volumes and makes changes:
docker run -v /some:/volume --name temp-container image-name /some/post-configure/command

# Replace the original image with the result:
# (reverting CMD to whatever it was, otherwise it will be set to /some/post-configure/command)   
docker commit --change="CMD bash" temp-container image-name 

# Delete the temporary container:
docker rm temp-container

In my use case I want to pre-generate a maven toolchains.xml file, but my many JDK installations are on a volume that isn't available until runtime. Some of my images are not compatible with all the JDKS, so I need to test compatibility at build time and populate toolchains.xml conditionally. Note that I don't need the image to be portable, I'm not publishing it to Docker Hub.

Your code is fine. What you are seeing is a linker issue.

If you put your code in a single file like this:

#include <iostream>
#include <string>

using namespace std;

string trim(const string& str)
{
    size_t first = str.find_first_not_of(' ');
    if (string::npos == first)
    {
        return str;
    }
    size_t last = str.find_last_not_of(' ');
    return str.substr(first, (last - first + 1));
}

int main() {
    string s = "abc ";
    cout << trim(s);

}

then do g++ test.cc and run a.out, you will see it works.

You should check if the file that contains the trim function is included in the link stage of your compilation process.

You're thinking about this the wrong way. You're thinking in logical steps each time cin or getline is used. Ex. First ask for a number, then ask for a name. That is the wrong way to think about cin. So you run into a race condition because you assume the stream is clear each time you ask for a input.

If you write your program purely for input you'll find the problem:

void main(void)
{
    double num;
    string mystr;

    cin >> num;
    getline(cin, mystr);

    cout << "num=" << num << ",mystr=\'" << mystr << "\'" << endl;
}

In the above, you are thinking, "first get a number." So you type in 123 press enter, and your output will be num=123,mystr=''. Why is that? It's because in the stream you have 123\n and the 123 is parsed into the num variable while \n is still in the stream. Reading the doc for getline function by default it will look in the istream until a \n is encountered. In this example, since \n is in the stream, it looks like it "skipped" it but it worked properly.

For the above to work, you'll have to enter 123Hello World which will properly output num=123,mystr='Hello World'. That, or you put a cin.ignore between the cin and getline so that it'll break into logical steps that you expect.

This is why you need the ignore command. Because you are thinking of it in logical steps rather than in a stream form so you run into a race condition.

Take another code example that is commonly found in schools:

void main(void)
{
    int age;
    string firstName;
    string lastName;

    cout << "First name: ";
    cin >> firstName;

    cout << "Last name: ";
    cin >> lastName;

    cout << "Age: ";
    cin >> age;

    cout << "Hello " << firstName << " " << lastName << "! You are " << age << " years old!" << endl;
}

The above seems to be in logical steps. First ask for first name, last name, then age. So if you did John enter, then Doe enter, then 19 enter, the application works each logic step. If you think of it in "streams" you can simply enter John Doe 19 on the "First name:" question and it would work as well and appear to skip the remaining questions. For the above to work in logical steps, you would need to ignore the remaining stream for each logical break in questions.

Just remember to think of your program input as it is reading from a "stream" and not in logical steps. Each time you call cin it is being read from a stream. This creates a rather buggy application if the user enters the wrong input. For example, if you entered a character where a cin >> double is expected, the application will produce a seemingly bizarre output.

If the value is a String, then this might work: map.entrySet().stream().collect(Collectors.toMap(e -> e.getKey(), e -> Optional.ofNullable(e.getValue()).orElse("")))

with in the code editor, Open the class you want to create the UID for , Right click -> Generate -> SerialVersionUID. You may need to have the GenerateSerialVersionUID plugin installed for this to work.

I needed to update and add suffix to few rows of the dataframe on conditional basis based on the another column's value of the same dataframe -

df with column Feature and Entity and need to update Entity based on specific feature type

df2= df1 df.loc[df.Feature == 'dnb', 'Entity'] = 'duns_' + df.loc[df.Feature == 'dnb','Entity']

The dropdown list appearing like that depends on what your browser is, as it is not possible to style this away for some. It looks like yours is IE9, but would look quite different in Chrome.

You could look to use something like this:

http://silviomoreto.github.io/bootstrap-select/

Which will make your selectboxes more consistent cross browser.

Your code is working fine using bootatrap v3.3.7, but you can use word-break: break-word if it's not working at your end.

which would then look like this -

You just also need to apply the color to 'tbody' element as that's the table body that's been causing our trouble by peeking underneath.
table, tbody, tr, th, td{ background-color: rgba(0, 0, 0, 0.0) !important; }

If you use Guava (v11 minimum) in your project you can use Maps::transformValues.

Map<String, Column> newColumnMap = Maps.transformValues(
  originalColumnMap,
  Column::new // equivalent to: x -> new Column(x) 
)

Note: The values of this map are evaluated lazily. If the transformation is expensive you can copy the result to a new map like suggested in the Guava docs.

To avoid lazy evaluation when the returned map doesn't need to be a view, copy the returned map into a new map of your choosing.

As some people already pointed out, spring-boot 1.4+, has specific namespaces for the four connections pools. By default, hikaricp is used in spring-boot 2+. So you will have to specify the SQL here. The default is SELECT 1. Here's what you would need for DB2 for example: spring.datasource.hikari.connection-test-query=SELECT current date FROM sysibm.sysdummy1

Caveat: If your driver supports JDBC4 we strongly recommend not setting this property. This is for "legacy" drivers that do not support the JDBC4 Connection.isValid() API. This is the query that will be executed just before a connection is given to you from the pool to validate that the connection to the database is still alive. Again, try running the pool without this property, HikariCP will log an error if your driver is not JDBC4 compliant to let you know. Default: none

Edit: see the end examples for ES6 updated examples.

This answer simply handle the case of direct parent-child relationship. When parent and child have potentially a lot of intermediaries, check this answer.

Other solutions are missing the point

While they still work fine, other answers are missing something very important.

Is there not a simple way to pass a child's props to its parent using events, in React.js?

The parent already has that child prop!: if the child has a prop, then it is because its parent provided that prop to the child! Why do you want the child to pass back the prop to the parent, while the parent obviously already has that prop?

Better implementation

Child: it really does not have to be more complicated than that.

var Child = React.createClass({
  render: function () {
    return <button onClick={this.props.onClick}>{this.props.text}</button>;
  },
});

Parent with single child: using the value it passes to the child

var Parent = React.createClass({
  getInitialState: function() {
     return {childText: "Click me! (parent prop)"};
  },
  render: function () {
    return (
      <Child onClick={this.handleChildClick} text={this.state.childText}/>
    );
  },
  handleChildClick: function(event) {
     // You can access the prop you pass to the children 
     // because you already have it! 
     // Here you have it in state but it could also be
     //  in props, coming from another parent.
     alert("The Child button text is: " + this.state.childText);
     // You can also access the target of the click here 
     // if you want to do some magic stuff
     alert("The Child HTML is: " + event.target.outerHTML);
  }
});

JsFiddle

Parent with list of children: you still have everything you need on the parent and don't need to make the child more complicated.

var Parent = React.createClass({
  getInitialState: function() {
     return {childrenData: [
         {childText: "Click me 1!", childNumber: 1},
         {childText: "Click me 2!", childNumber: 2}
     ]};
  },
  render: function () {
    var children = this.state.childrenData.map(function(childData,childIndex) {
        return <Child onClick={this.handleChildClick.bind(null,childData)} text={childData.childText}/>;
    }.bind(this));
    return <div>{children}</div>;
  },

  handleChildClick: function(childData,event) {
     alert("The Child button data is: " + childData.childText + " - " + childData.childNumber);
     alert("The Child HTML is: " + event.target.outerHTML);
  }
});

JsFiddle

It is also possible to use this.handleChildClick.bind(null,childIndex) and then use this.state.childrenData[childIndex]

Note we are binding with a null context because otherwise React issues a warning related to its autobinding system. Using null means you don't want to change the function context. See also.

About encapsulation and coupling in other answers

This is for me a bad idea in term of coupling and encapsulation:

var Parent = React.createClass({
  handleClick: function(childComponent) {
     // using childComponent.props
     // using childComponent.refs.button
     // or anything else using childComponent
  },
  render: function() {
    <Child onClick={this.handleClick} />
  }
});

Using props: As I explained above, you already have the props in the parent so it's useless to pass the whole child component to access props.

Using refs: You already have the click target in the event, and in most case this is enough. Additionnally, you could have used a ref directly on the child:

<Child ref="theChild" .../>

And access the DOM node in the parent with

React.findDOMNode(this.refs.theChild)

For more advanced cases where you want to access multiple refs of the child in the parent, the child could pass all the dom nodes directly in the callback.

The component has an interface (props) and the parent should not assume anything about the inner working of the child, including its inner DOM structure or which DOM nodes it declares refs for. A parent using a ref of a child means that you tightly couple the 2 components.

To illustrate the issue, I'll take this quote about the Shadow DOM, that is used inside browsers to render things like sliders, scrollbars, video players...:

They created a boundary between what you, the Web developer can reach and what’s considered implementation details, thus inaccessible to you. The browser however, can traipse across this boundary at will. With this boundary in place, they were able to build all HTML elements using the same good-old Web technologies, out of the divs and spans just like you would.

The problem is that if you let the child implementation details leak into the parent, you make it very hard to refactor the child without affecting the parent. This means as a library author (or as a browser editor with Shadow DOM) this is very dangerous because you let the client access too much, making it very hard to upgrade code without breaking retrocompatibility.

If Chrome had implemented its scrollbar letting the client access the inner dom nodes of that scrollbar, this means that the client may have the possibility to simply break that scrollbar, and that apps would break more easily when Chrome perform its auto-update after refactoring the scrollbar... Instead, they only give access to some safe things like customizing some parts of the scrollbar with CSS.

About using anything else

Passing the whole component in the callback is dangerous and may lead novice developers to do very weird things like calling childComponent.setState(...) or childComponent.forceUpdate(), or assigning it new variables, inside the parent, making the whole app much harder to reason about.

Edit: ES6 examples

As many people now use ES6, here are the same examples for ES6 syntax

The child can be very simple:

const Child = ({
  onClick, 
  text
}) => (
  <button onClick={onClick}>
    {text}
  </button>
)

The parent can be either a class (and it can eventually manage the state itself, but I'm passing it as props here:

class Parent1 extends React.Component {
  handleChildClick(childData,event) {
     alert("The Child button data is: " + childData.childText + " - " + childData.childNumber);
     alert("The Child HTML is: " + event.target.outerHTML);
  }
  render() {
    return (
      <div>
        {this.props.childrenData.map(child => (
          <Child
            key={child.childNumber}
            text={child.childText} 
            onClick={e => this.handleChildClick(child,e)}
          />
        ))}
      </div>
    );
  }
}

But it can also be simplified if it does not need to manage state:

const Parent2 = ({childrenData}) => (
  <div>
     {childrenData.map(child => (
       <Child
         key={child.childNumber}
         text={child.childText} 
         onClick={e => {
            alert("The Child button data is: " + child.childText + " - " + child.childNumber);
                    alert("The Child HTML is: " + e.target.outerHTML);
         }}
       />
     ))}
  </div>
)

JsFiddle

PERF WARNING (apply to ES5/ES6): if you are using PureComponent or shouldComponentUpdate, the above implementations will not be optimized by default because using onClick={e => doSomething()}, or binding directly during the render phase, because it will create a new function everytime the parent renders. If this is a perf bottleneck in your app, you can pass the data to the children, and reinject it inside "stable" callback (set on the parent class, and binded to this in class constructor) so that PureComponent optimization can kick in, or you can implement your own shouldComponentUpdate and ignore the callback in the props comparison check.

You can also use Recompose library, which provide higher order components to achieve fine-tuned optimisations:

// A component that is expensive to render
const ExpensiveComponent = ({ propA, propB }) => {...}

// Optimized version of same component, using shallow comparison of props
// Same effect as React's PureRenderMixin
const OptimizedComponent = pure(ExpensiveComponent)

// Even more optimized: only updates if specific prop keys have changed
const HyperOptimizedComponent = onlyUpdateForKeys(['propA', 'propB'])(ExpensiveComponent)

In this case you could optimize the Child component by using:

const OptimizedChild = onlyUpdateForKeys(['text'])(Child)

Client Upload

If you want to upload a single file with Python requests library, then requests lib supports streaming uploads, which allow you to send large files or streams without reading into memory.

with open('massive-body', 'rb') as f:
    requests.post('http://some.url/streamed', data=f)

Server Side

Then store the file on the server.py side such that save the stream into file without loading into the memory. Following is an example with using Flask file uploads.

@app.route("/upload", methods=['POST'])
def upload_file():
    from werkzeug.datastructures import FileStorage
    FileStorage(request.stream).save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
    return 'OK', 200

Or use werkzeug Form Data Parsing as mentioned in a fix for the issue of "large file uploads eating up memory" in order to avoid using memory inefficiently on large files upload (s.t. 22 GiB file in ~60 seconds. Memory usage is constant at about 13 MiB.).

@app.route("/upload", methods=['POST'])
def upload_file():
    def custom_stream_factory(total_content_length, filename, content_type, content_length=None):
        import tempfile
        tmpfile = tempfile.NamedTemporaryFile('wb+', prefix='flaskapp', suffix='.nc')
        app.logger.info("start receiving file ... filename => " + str(tmpfile.name))
        return tmpfile

    import werkzeug, flask
    stream, form, files = werkzeug.formparser.parse_form_data(flask.request.environ, stream_factory=custom_stream_factory)
    for fil in files.values():
        app.logger.info(" ".join(["saved form name", fil.name, "submitted as", fil.filename, "to temporary file", fil.stream.name]))
        # Do whatever with stored file at `fil.stream.name`
    return 'OK', 200

Try:

s = ''.join(filter(str.isalnum, s))

This will take every char from the string, keep only alphanumeric ones and build a string back from them.

Youtube uses iframe. You can simply set it to:

iframe {
   display: block;
   margin: 0 auto;
}

I made some modification to @jvd10's solution. The '!important' seems too strong that the container doesn't adapt well when TOC sidebar is displayed. I removed it and added 'min-width' to limit the minimal width.

Here is my .juyputer/custom/custom.css:

/* Make the notebook cells take almost all available width and limit minimal width to 1110px */
.container {
    width: 99%;
    min-width: 1110px;
}   

/* Prevent the edit cell highlight box from getting clipped;
 * important so that it also works when cell is in edit mode*/
div.cell.selected {
    border-left-width: 1px;
}

this code working for socketError 11004 and 10060......

Could it be a problem with past preview versions of Android Studio ? nowadays "beta" has replaced the "preview". I try it out step by step debugging while using Memory Monitor at same time by Android Studio (Beta) 0.8.11 on OSX 10.9.5 without any problems.

The tutorial Debugging with Android Studio also helps, specially this paragraph :

To track memory allocation of objects:

1. Start your app as described in Run Your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. On the Android DDMS tool window, select the Devices | logcat tab.
4. Select your device from the dropdown list.
5. Select your app by its package name from the list of running apps.
6. Click Start Allocation Tracking Interact with your app on the device. Click Stop Allocation Tracking

Here a couple of screenshot while debugging step by step on a breakpoint a monitoring the memory on the emulator:

Just this!

$(function () {
    $('#date').datetimepicker({
         format: 'H:m',
    });

});

i use v4 and work well!!

Following up on Chad's excellent answer, if you get an error of "Error: Could not find or load main class" - and you spend a couple hours trying to troubleshoot it, whether your executing a shell script that starts your java app or starting it from systemd itself - and you know your classpath is 100% correct, e.g. manually running the shell script works as well as running what you have in systemd execstart. Be sure you're running things as the correct user! In my case, I had tried different users, after quite a while of troubleshooting - i finally had a hunch, put root as the user - voila, the app started correctly. After determining it was a wrong user issue, I chown -R user:user the folder and subfolders and the app ran correctly as the specified user and group so no longer needed to run it as root (bad security).

I made a sketchy benchmark on the three methods described in other responses.

Obviously pre-allocating the slice before pulling the keys is faster than appending, but surprisingly, the reflect.ValueOf(m).MapKeys() method is significantly slower than the latter:

? go run scratch.go
populating
filling 100000000 slots
done in 56.630774791s
running prealloc
took: 9.989049786s
running append
took: 18.948676741s
running reflect
took: 25.50070649s

Here's the code: https://play.golang.org/p/Z8O6a2jyfTH (running it in the playground aborts claiming that it takes too long, so, well, run it locally.)

Your variable size is declared as: float size;

You can't use a floating point variable as the size of an array - it needs to be an integer value.

You could cast it to convert to an integer:

float *temp = new float[(int)size];

Your other problem is likely because you're writing outside of the bounds of the array:

   float *temp = new float[size];

    //Getting input from the user
    for (int x = 1; x <= size; x++){
        cout << "Enter temperature " << x << ": ";

        // cin >> temp[x];
        // This should be:
        cin >> temp[x - 1];
    }

Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.

In the new rspec expect syntax this would be:

expect(subject).to receive(:bar).with("an argument I want")

Worked example for a specific case:

Let's say you have my-module that you're sharing via npm.

You install it with npm install my-module

You use it thus:

import * as lol from 'my-module';

const a = lol('abc', 'def');

The module's logic is all in index.js:

module.exports = function(firstString, secondString) {

  // your code

  return result
}

To add typings, create a file index.d.ts:

declare module 'my-module' {
  export default function anyName(arg1: string, arg2: string): MyResponse;
}

interface MyResponse {
  something: number;
  anything: number;
}

Among them, a free tool: Long Path Fixer is good to try: http://corz.org/windows/software/accessories/Long-Path-Fixer-for-Windows.php

I created a little javascript tool to style elements on screen size without using media queries or recompiling bootstrap css:

https://github.com/Heras/Responsive-Breakpoints

Just add class responsive-breakpoints to any element, and it will automagically add xs sm md lg xl classes to those elements.

Demo: https://codepen.io/HerasHackwork/pen/rGGNEK

You can use a special React attribute called ref and then match the real DOM nodes in the onChange event using React's getDOMNode() function:

handleClick: function(event) {
  if (event.target === this.refs.prev.getDOMNode()) {
    ...
  }
}

render: function() {
  ...
  <button ref="prev" onClick={this.handleClick}>Previous question</button>
  <button ref="next" onClick={this.handleClick}>Next question</button>
  ...
}

I've updated the class using refs as all the solutions I see on here have things that are no longer supported or will soon be depreciated like ReactDOM.findDOMNode. Can be parent to a child component or a group of children :)

I was just looking for a smiliar issue and I found this:

.div{
  height : 100vh;
}

more info

vw: 1/100th viewport width
vh: 1/100th viewport height
vmin: 1/100th of the smallest side
vmax: 1/100th of the largest side

I was having problems here (i.e. sending form-data whilst uploading a file) until I used the following:

files = {'file': (filename, open(filepath, 'rb'), 'text/xml'),
         'Content-Disposition': 'form-data; name="file"; filename="' + filename + '"',
         'Content-Type': 'text/xml'}

That's the input that ended up working for me. In Chrome Dev Tools -> Network tab, I clicked the request I was interested in. In the Headers tab, there's a Form Data section, and it showed both the Content-Disposition and the Content-Type headers being set there.

I did NOT need to set headers in the actual requests.post() command for this to succeed (including them actually caused it to fail)

For those who have a file from an input control, don't know what its orientation is, are a bit lazy and don't want to include a large library below is the code provided by @WunderBart melded with the answer he links to (https://stackoverflow.com/a/32490603) that finds the orientation.

function getDataUrl(file, callback2) {
        var callback = function (srcOrientation) {
            var reader2 = new FileReader();
            reader2.onload = function (e) {
                var srcBase64 = e.target.result;
                var img = new Image();

                img.onload = function () {
                    var width = img.width,
                        height = img.height,
                        canvas = document.createElement('canvas'),
                        ctx = canvas.getContext("2d");

                    // set proper canvas dimensions before transform & export
                    if (4 < srcOrientation && srcOrientation < 9) {
                        canvas.width = height;
                        canvas.height = width;
                    } else {
                        canvas.width = width;
                        canvas.height = height;
                    }

                    // transform context before drawing image
                    switch (srcOrientation) {
                        case 2: ctx.transform(-1, 0, 0, 1, width, 0); break;
                        case 3: ctx.transform(-1, 0, 0, -1, width, height); break;
                        case 4: ctx.transform(1, 0, 0, -1, 0, height); break;
                        case 5: ctx.transform(0, 1, 1, 0, 0, 0); break;
                        case 6: ctx.transform(0, 1, -1, 0, height, 0); break;
                        case 7: ctx.transform(0, -1, -1, 0, height, width); break;
                        case 8: ctx.transform(0, -1, 1, 0, 0, width); break;
                        default: break;
                    }

                    // draw image
                    ctx.drawImage(img, 0, 0);

                    // export base64
                    callback2(canvas.toDataURL());
                };

                img.src = srcBase64;
            }

            reader2.readAsDataURL(file);
        }

        var reader = new FileReader();
        reader.onload = function (e) {

            var view = new DataView(e.target.result);
            if (view.getUint16(0, false) != 0xFFD8) return callback(-2);
            var length = view.byteLength, offset = 2;
            while (offset < length) {
                var marker = view.getUint16(offset, false);
                offset += 2;
                if (marker == 0xFFE1) {
                    if (view.getUint32(offset += 2, false) != 0x45786966) return callback(-1);
                    var little = view.getUint16(offset += 6, false) == 0x4949;
                    offset += view.getUint32(offset + 4, little);
                    var tags = view.getUint16(offset, little);
                    offset += 2;
                    for (var i = 0; i < tags; i++)
                        if (view.getUint16(offset + (i * 12), little) == 0x0112)
                            return callback(view.getUint16(offset + (i * 12) + 8, little));
                }
                else if ((marker & 0xFF00) != 0xFF00) break;
                else offset += view.getUint16(offset, false);
            }
            return callback(-1);
        };
        reader.readAsArrayBuffer(file);
    }

which can easily be called like such

getDataUrl(input.files[0], function (imgBase64) {
      vm.user.BioPhoto = imgBase64;
});

If you need a specific exit status, Ansible provides a way to do that via callback plugins.

Example. It's a very good option if you need a 100% accurate exit status.

If not, you can always use the Debug Module, which is the standard for this cases of use.

I created a script to ignore differences in line endings:

It will display the files which are not added to the commit list and were modified (after ignoring differences in line endings). You can add the argument "add" to add those files to your commit.

#!/usr/bin/perl

# Usage: ./gitdiff.pl [add]
#    add : add modified files to git

use warnings;
use strict;

my ($auto_add) = @ARGV;
if(!defined $auto_add) {
    $auto_add = "";
}

my @mods = `git status --porcelain 2>/dev/null | grep '^ M ' | cut -c4-`;
chomp(@mods);
for my $mod (@mods) {
    my $diff = `git diff -b $mod 2>/dev/null`;
    if($diff) {
        print $mod."\n";
        if($auto_add eq "add") {
            `git add $mod 2>/dev/null`;
        }
    }
}

• fix by evandro777 : When the file has space in filename or directory

Using Set and converting it to an array is very similar to copying an Array...

So you can use the same methods for copying an array which is very easy in ES6

For example, you can use ...

Imagine you have this Set below:

const a = new Set(["Alireza", "Dezfoolian", "is", "a", "developer"]);

You can simply convert it using:

const b = [...a];

and the result is:

["Alireza", "Dezfoolian", "is", "a", "developer"]

An array and now you can use all methods that you can use for an array...

Other common ways of doing it:

const b = Array.from(a);

or using loops like:

const b = [];
a.forEach(v => b.push(v));

I also meet this situation and finally fixed it.

Firstly, I will describe my situation. I have two nodes in ElasticSearch cluster, they can find each other, but when I created a index with settings "number_of_replicas" : 2, "number_of_shards" : 5, ES show yellow signal and unassigned_shards is 5.

The problem occurs because the value of number_of_replicas, when I set its value with 1, all is fine.

Either do it with CSS like the other answers did or change the text style color directly via the onMouseOver and onMouseOut event:

onmouseover="this.bgColor='white'; this.style.color='black'"

onmouseout="this.bgColor='black'; this.style.color='white'"

You can declare trk by the following ways : - either

trk : [{
    lat : String,
    lng : String
     }]

or

trk : { type : Array , "default" : [] }

In the second case during insertion make the object and push it into the array like

db.update({'Searching criteria goes here'},
{
 $push : {
    trk :  {
             "lat": 50.3293714,
             "lng": 6.9389939
           } //inserted data is the object to be inserted 
  }
});

or you can set the Array of object by

db.update ({'seraching criteria goes here ' },
{
 $set : {
          trk : [ {
                     "lat": 50.3293714,
                     "lng": 6.9389939
                  },
                  {
                     "lat": 50.3293284,
                     "lng": 6.9389634
                  }
               ]//'inserted Array containing the list of object'
      }
});

In case you are using docker/docker-compose and want to prevent redis from writing to file, you can create a redis config and mount into a container

docker.compose.override.yml

  redis:¬
      volumes:¬
        - ./redis.conf:/usr/local/etc/redis/redis.conf¬
      ports:¬
        - 6379:6379¬

You can download the default config from here

in the redis.conf file make sure you comment out these 3 lines

save 900 1
save 300 10
save 60 10000

myou can view more solutions for removing the persistent data here

seems like in Angular 1.3.12 you do not need the inner ng-repeat anymore, the outer loop returns the values of the collection is a single map entry

MVP:

Advantages:

Presenter will be present in between Model and view.Presenter will fetch data from Model and will do manipulations for data as view wants and give it to view and view is responsible only for rendering.

Disadvantages:

1)We can't use presenter for multiple modules because data is being modified in presenter as desired by one view class.

3)Breaking Clean architecture because data flow should be only outwards but here data is coming back from presenter to View.

MVC:

Advanatages:

Here we have Controller in between view and model.Here data request will be done from controller to view but data will be sent back to view in form of interface but not with controller.So,here controller won't get bloated up because of many transactions.

Disadvantagaes:

Data Manipulation should be done by View as it wants and this will be extra work on UI thread which may effect UI rendering if data processing is more.

MVVM:

After announcing Architectural components,we got access to ViewModel which provided us biggest advantage i.e it's lifecycle aware.So,it won't notify data if view is not available.It is a clean architecture because flow is only in forward mode and data will be notified automatically by LiveData. So,it is Android's recommended architecture.

Even MVVM has a disadvantage. Since it is a lifecycle aware some concepts like alarm or reminder should come outside app.So,in this scenario we can't use MVVM.

How about using a simple loop to count the occurrences of number of spaces!?

txt = "Just an example here move along" _x000D_
count = 1_x000D_
for i in txt:_x000D_
if i == " ":_x000D_
   count += 1_x000D_
print(count)

I would use table and implement the pagination in the controller to control how much is shown and buttons to move to the next page. This Fiddle might help you.

 <table class="table table-striped table-condensed table-hover">
                <thead>

                </tbody>
            </table> 

the $scope.range in the fiddle example should be:

$scope.range = function (size,start, end) {
    var ret = [];        
    console.log(size,start, end);

       if (size < end) {
        end = size;
        if(size<$scope.gap){
             start = 0;
        }else{
             start = size-$scope.gap;
        }

    }
    for (var i = start; i < end; i++) {
        ret.push(i);
    }        
     console.log(ret);        
    return ret;
};

Just for someone looking for a solution more similar to R:

df[(df.Product == p_id) & (df.Time> start_time) & (df.Time < end_time)][['Time','Product']]

No need for data.loc or query, but I do think it is a bit long.

You can create a jQuery function to unload Bootstrap CSS files at the size of 768px, and load it back when resized to lower width. This way you can design a mobile website without touching the desktop version, by using col-xs-* only

function resize() {
if ($(window).width() > 767) {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', true);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', true);
}   
else {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', false);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', false);
}
}

and

$(document).ready(function() {
$(window).resize(resize);
resize();   

if ($(window).width() > 767) {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', true);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', true);
}
});

I somehow absolutely missed the actual command in the accepted answer, so here it is again, bit more visible in its own paragraph, to see how many people are like me

$ docker history --no-trunc <IMAGE_ID>

Here's mine. It runs in <2ms in Google Apps Script on a sizable object. It uses dashes instead of dots for separators, and it doesn't handle arrays specially like in the asker's question, but this is what I wanted for my use.

function flatten (obj) {
  var newObj = {};
  for (var key in obj) {
    if (typeof obj[key] === 'object' && obj[key] !== null) {
      var temp = flatten(obj[key])
      for (var key2 in temp) {
        newObj[key+"-"+key2] = temp[key2];
      }
    } else {
      newObj[key] = obj[key];
    }
  }
  return newObj;
}

Example:

var test = {
  a: 1,
  b: 2,
  c: {
    c1: 3.1,
    c2: 3.2
  },
  d: 4,
  e: {
    e1: 5.1,
    e2: 5.2,
    e3: {
      e3a: 5.31,
      e3b: 5.32
    },
    e4: 5.4
  },
  f: 6
}

Logger.log("start");
Logger.log(JSON.stringify(flatten(test),null,2));
Logger.log("done");

Example output:

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

This is what worked for me perfectly:-

// slide the view from its current position to below itself
public void slideUp(final View view, final View llDomestic){

    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",0f);
    animation.setDuration(100);
    llDomestic.setVisibility(View.GONE);
    animation.start();

}

// slide the view from below itself to the current position
public void slideDown(View view,View llDomestic){
    llDomestic.setVisibility(View.VISIBLE);
    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",   0f);
    animation.setDuration(100);
    animation.start();
}

llDomestic : The view which you want to hide. view: The view which you want to move down or up.

Or you might be looking at this question because you happened to make a silly typo like I did and have the =~ reversed to ~=

In general, to make a raw string out of a string variable, I use this:

string = "C:\\Windows\Users\alexb"

raw_string = r"{}".format(string)

output:

'C:\\\\Windows\\Users\\alexb'

You can use prettytable to render the table as text. The trick is to convert the data_frame to an in-memory csv file and have prettytable read it. Here's the code:

from StringIO import StringIO
import prettytable    

output = StringIO()
data_frame.to_csv(output)
output.seek(0)
pt = prettytable.from_csv(output)
print pt

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

Rendering didn't work for me too. I had <null> value on the right side of the android icon. I ran

sudo apt-get install gradle

I restarted Android studio then and <null> value changed to 23.

Voila, it renders now! :)

Found in a google discussion group. Works for me.

var $injector = angular.injector(['ng', 'myApp']);
$injector.invoke(function($rootScope, $compile) {
  $compile(element)($rootScope);
});

Check this fully functional directive for MEAN.JS (Angular.js, bootstrap, Express.js and MongoDb)

Based on @Blackhole ´s response, we just finished it to be used with mongodb and express.

It will allow you to save and load dates from a mongoose connector

Hope it Helps!!

angular.module('myApp')
.directive(
  'dateInput',
  function(dateFilter) {
    return {
      require: 'ngModel',
      template: '<input type="date" class="form-control"></input>',
      replace: true,
      link: function(scope, elm, attrs, ngModelCtrl) {
        ngModelCtrl.$formatters.unshift(function (modelValue) {
          return dateFilter(modelValue, 'yyyy-MM-dd');
        });

        ngModelCtrl.$parsers.push(function(modelValue){
           return angular.toJson(modelValue,true)
          .substring(1,angular.toJson(modelValue).length-1);
        })

      }
    };
  });

The JADE/HTML:

div(date-input, ng-model="modelDate")

In response to Dan (https://stackoverflow.com/a/20048559/4298604), I would recommend a slightly altered version.

<div onclick="void(0)">Click Me!</div>

Adding "void(0)" helps to obtain the undefined primitive value, as opposed to "".

How about the List.FindIndex Method:

int index = myList.FindIndex(a => a.Prop == oProp);

This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.

If the item is not found, it will return -1

There is build in forEach loop for array in ECMAScript 5th Edition.

var buttons = document.getElementsByClassName("navButton");

Array.prototype.forEach.call(buttons,function(button) { 
    button.setAttribute("class", "active");
    button.setAttribute("src", "images/arrows/top_o.png"); 
});

In addition to @Jason's answer I had to do a bit more to get my app to run.

• Download & unzip Eclipse IDE for Java EE Developers (Note the EE edition)
• Download & unzip Eclipse's Web Tools Platform Stable (Milestone) 3.6+
• Overwrite the two folders in the Eclipse IDE, with the WTP folder(s) (features & plugins folders)
• Download and unzip Tomcat 8
• In eclipse new -> other -> server -> Tomcat 8 (choose the unzipped location)
• If you get a 404, click the Tomcat 8 in the Servers view -> Server Locations -> Change to Use Tomcat installation, and change the Deploy path: to webapps * (If you can't edit this, delete any published webapps)

If you want to browse your databases FROM WITHIN ANDROID STUDIO, here's what I'm using:

Go to Files / Settings / Plugins and look for this:

... After having restarted Android Studio you can pick your downloaded database file like this:

... Click the "Open SQL Console" icon, and you end up with this nice view of your database inside Android Studio:

You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:

>>> print(etree.tostring(root, pretty_print=True))
<root>
  <child1/>
  <child2/>
  <child3/>
</root>

In 2019, I think git branch --show-current is a better command than the accepted answer.

$ git branch --show-current
master

(Added in git 2.22 release in June 2019)

It runs much faster as it doesn't need to iterate through all branches. Similarly git branch should be avoided too in the command prompt as it slows down your prompt if you have many local branches.

Put it in a function to use anywhere on command prompt:

  # This function returns '' in all below cases:
  #   - git not installed or command not found
  #   - not in a git repo
  #   - in a git repo but not on a branch (HEAD detached)
  get_git_current_branch() {
    git branch --show-current 2> /dev/null
  }

More context:

$ git version
git version 2.23.0

you can use setAttribute function in Model to add a custom attribute

One of the main purposes of integration testing with MockMvc is to verify that model objects are correclty populated with form data.

In order to do it you have to pass form data as they're passed from actual form (using .param()). If you use some automatic conversion from NewObject to from data, your test won't cover particular class of possible problems (modifications of NewObject incompatible with actual form).

At least on 10.10.5, system_profiler SPUSBDataType output is NOT dynamically updated when a new USB device gets plugged in, while ioreg -p IOUSB -l -w 0 does.

When the Resolve Conflicts->Content Menu are disabled, one may be on the Pending files list. We need to select the Conflicted files option from the drop down (top)

hope it helps

Abstract Class : Use it when there is strong is-a relation between super class and sub class and all subclass share some common behavior .

Interface : It define just protocol which all subclass need to follow.

With the following streaming code, the Python memory usage is restricted regardless of the size of the downloaded file:

def download_file(url):
    local_filename = url.split('/')[-1]
    # NOTE the stream=True parameter below
    with requests.get(url, stream=True) as r:
        r.raise_for_status()
        with open(local_filename, 'wb') as f:
            for chunk in r.iter_content(chunk_size=8192): 
                # If you have chunk encoded response uncomment if
                # and set chunk_size parameter to None.
                #if chunk: 
                f.write(chunk)
    return local_filename

Note that the number of bytes returned using iter_content is not exactly the chunk_size; it's expected to be a random number that is often far bigger, and is expected to be different in every iteration.

See body-content-workflow and Response.iter_content for further reference.

Edit: Harhar is now open source. I have updated the URL below.

If you use an Avalanche load generator, you can use Harhar to replay a HAR file at very high load: https://acastaner.github.io/harhar/

This tool handles the "content" you use when you "Save as HAR with content."

I see you try to set ylim but you give bad values. This will change the scale of the plot (like a zoom). For example see this:

par(mfrow=c(2,1))
tN <- table(Ni <- stats::rpois(100, lambda = 5))
r <- barplot(tN, col = rainbow(20),ylim=c(0,50),main='long y-axis')
r <- barplot(tN, col = rainbow(20),main='short y axis')

Another option is to plot without axes and set them manually using axis and usr:

require(grDevices) # for colours
par(mfrow=c(1,1))
r <- barplot(tN, col = rainbow(20),main='short y axis',ann=FALSE,axes=FALSE)
usr <- par("usr")
par(usr=c(usr[1:2], 0, 20))
axis(2,at=seq(0,20,5))

Use the exp1 if cond else exp2 syntax.

rate = lambda T: 200*exp(-T) if T>200 else 400*exp(-T)

Note you don't use return in lambda expressions.

If handled as an array is much easier

Return the total amount of fruits:

let fruits = [{ name: 'banana', id: 0, quantity: 9 }, { name: 'strawberry', id: 1, quantity: 1 }, { name: 'kiwi', id: 2, quantity: 2 }, { name: 'apple', id: 3, quantity: 4 }]

let total = fruits.reduce((sum, f) => sum + f.quantity, 0);

I don't think this is OP's problem, but if you're like me, you ran into this error while you were trying to play around with git plumbing commands (update-index & cat-file) without ever actually committing anything in the first place. So try committing something (git commit -am 'First commit') and your problem should be solved.

According to eduLINQ:

The best way to get to grips with what GroupJoin does is to think of Join. There, the overall idea was that we looked through the "outer" input sequence, found all the matching items from the "inner" sequence (based on a key projection on each sequence) and then yielded pairs of matching elements. GroupJoin is similar, except that instead of yielding pairs of elements, it yields a single result for each "outer" item based on that item and the sequence of matching "inner" items.

The only difference is in return statement:

Join:

var lookup = inner.ToLookup(innerKeySelector, comparer); 
foreach (var outerElement in outer) 
{ 
    var key = outerKeySelector(outerElement); 
    foreach (var innerElement in lookup[key]) 
    { 
        yield return resultSelector(outerElement, innerElement); 
    } 
} 

GroupJoin:

var lookup = inner.ToLookup(innerKeySelector, comparer); 
foreach (var outerElement in outer) 
{ 
    var key = outerKeySelector(outerElement); 
    yield return resultSelector(outerElement, lookup[key]); 
}

Laravel 5.2

If you are using a another Middleware like Admin middleware you can set a session for url.intended by using this following:

Basically we need to set manually \Session::put('url.intended', \URL::full()); for redirect.

Example

  if (\Auth::guard($guard)->guest()) {
      if ($request->ajax() || $request->wantsJson()) {
         return response('Unauthorized.', 401);
      } else {
        \Session::put('url.intended', \URL::full());
        return redirect('login');
      }
  }

On login attempt

Make sure on login attempt use return \Redirect::intended('default_path');

This is how I do it if I need a form displayed for each item, and inputs for various properties. Really depends on what I'm trying to do though.

ViewModel looks like this:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

View(with BeginForm of course):

@model MyViewModel


@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

Action:

[HttpPost]public ViewResult(MyViewModel vm)
{
...

Note that on post back only properties which had inputs available will have values. I.e., if Person had a .SSN property, it would not be available in the post action because it wasn't a field in the form.

Note that the way MVC's model binding works, it will only look for consecutive ID's. So doing something like this where you conditionally hide an item will cause it to not bind any data after the 5th item, because once it encounters a gap in the IDs, it will stop binding. Even if there were 10 people, you would only get the first 4 on the postback:

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    if(i != 4)//conditionally hide 5th item, 
    { //but BUG occurs on postback, all items after 5th will not be bound to the the list
      @Html.HiddenFor(m => m.Persons[i].PersonId)
      @Html.EditorFor(m => m.Persons[i].FirstName) 
      @Html.EditorFor(m => m.Persons[i].LastName)           
    }
}

When your script is running, it blocks the page from doing anything. You can work around this with one of two ways:

• Use var foo = prompt("Give me input");, which will give you the string that the user enters into a popup box (or null if they cancel it)
• Split your code into two function - run one function to set up the user interface, then provide the second function as a callback that gets run when the user clicks the button.

If any exception occurs, the transaction will rollback automatically.

Laravel Basic transaction format

    try{
    DB::beginTransaction();

    /* 
    * SQL operation one 
    * SQL operation two
    ..................     
    ..................     
    * SQL operation n */


    DB::commit();
   /* Transaction successful. */
}catch(\Exception $e){       

    DB::rollback();
    /* Transaction failed. */
}

Unfortunately, the string.encode() method is not always reliable. Check out this thread for more information: What is the fool proof way to convert some string (utf-8 or else) to a simple ASCII string in python

As @PavelAnossov answered, the canonical answer, use the word_tokenize function in nltk:

from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)

If your sentence is truly simple enough:

Using the string.punctuation set, remove punctuation then split using the whitespace delimiter:

import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y

Laravel 6 Update:

@php
$value = 'Artificial Intelligence';
$var = Str::limit($value, $limit = 15, $end = '');
print_r($var);
@endphp

<p class="card-text">{{ Illuminate\Support\Str::limit($value, 7) }}</p>
<h2 class="main-head">{!! Str::limit($value, 5) !!}</h2>

Nothing works in my case using the scripts above but I was able to close these figures from eclipse console bar by clicking on Terminate ALL (two red nested squares icon).

In order to view only first few entries you can use, pandas head function which is used as

dataframe.head(any number)        // default is 5
dataframe.head(n=value)

or you can also you slicing for this purpose, which can also give the same result,

dataframe[:n]

In order to view the last few entries you can use pandas tail() in a similar way,

dataframe.tail(any number)        // default is 5
dataframe.tail(n=value)

THIS DOESN'T USE PIPEs, but requires a single tempfile
I used this to put simplified timestamps into a lowtech daily maintenance batfile

We have already Short-formatted our System-Time to HHmm, (which is 2245 for 10:45PM)
I direct output of Maint-Routines to logfiles with a $DATE%@%TIME% timestamp;
. . . but %TIME% is a long ugly string (ex. 224513.56, for down to the hundredths of a sec)

SOLUTION OVERVIEW:
1. Use redirection (">") to send the command "TIME /T" everytime to OVERWRITE a temp-file in the %TEMP% DIRECTORY
2. Then use that tempfile as the input to set a new variable (I called it NOW)
3. Replace

echo $DATE%@%TIME% blah-blah-blah >> %logfile%

echo $DATE%@%NOW% blah-blah-blah >> %logfile%

SUCCESSFUL TIMESYNCH [email protected]

SUCCESSFUL TIMESYNCH 29Dec14@2252

ACTUAL CODE:

TIME /T > %TEMP%\DailyTemp.txt
SET /p NOW=<%TEMP%\DailyTemp.txt
echo $DATE%@%NOW% blah-blah-blah >> %logfile%

AFTERMATH:
All that remains afterwards is the appended logfile, and constantly overwritten tempfile. And if the Tempfile is ever deleted, it will be re-created as necessary.

You can use some online websites to beautify JSON, such as: JSON Formatter, and then paste the beautified result to WIKI

You could use cjson, that claims to be up to 250 times faster than pure-python implementations, given that you have "some long complicated JSON file" and you will probably need to run it several times (decoders fail and report the first error they encounter only).

Inline SVG can be used in IE 10 and 11 and Edge 12.

I've created a project called gray which includes a polyfill for these browsers. The polyfill switches out <img> tags with inline SVG: https://github.com/karlhorky/gray

To implement, the short version is to download the jQuery plugin at the GitHub link above and add after jQuery at the end of your body:

<script src="/js/jquery.gray.min.js"></script>

Then every image with the class grayscale will appear as gray.

<img src="/img/color.jpg" class="grayscale">

You can see a demo too if you like.

# start with the mtcars data frame (included with your installation of R)
mtcars

# pick your 'group by' variable
gbv <- 'cyl'
# IMPORTANT NOTE: you can only include one group by variable here
# ..if you need more, the `order` function below will need
# one per inputted parameter: order( x$cyl , x$am )

# choose whether you want to find the minimum or maximum
find.maximum <- FALSE

# create a simple data frame with only two columns
x <- mtcars

# order it based on 
x <- x[ order( x[ , gbv ] , decreasing = find.maximum ) , ]

# figure out the ranks of each miles-per-gallon, within cyl columns
if ( find.maximum ){
    # note the negative sign (which changes the order of mpg)
    # *and* the `rev` function, which flips the order of the `tapply` result
    x$ranks <- unlist( rev( tapply( -x$mpg , x[ , gbv ] , rank ) ) )
} else {
    x$ranks <- unlist( tapply( x$mpg , x[ , gbv ] , rank ) )
}
# now just subset it based on the rank column
result <- x[ x$ranks <= 3 , ]

# look at your results
result

# done!

# but note only *two* values where cyl == 4 were kept,
# because there was a tie for third smallest, and the `rank` function gave both '3.5'
x[ x$ranks == 3.5 , ]

# ..if you instead wanted to keep all ties, you could change the
# tie-breaking behavior of the `rank` function.
# using the `min` *includes* all ties.  using `max` would *exclude* all ties
if ( find.maximum ){
    # note the negative sign (which changes the order of mpg)
    # *and* the `rev` function, which flips the order of the `tapply` result
    x$ranks <- unlist( rev( tapply( -x$mpg , x[ , gbv ] , rank , ties.method = 'min' ) ) )
} else {
    x$ranks <- unlist( tapply( x$mpg , x[ , gbv ] , rank , ties.method = 'min' ) )
}
# and there are even more options..
# see ?rank for more methods

# now just subset it based on the rank column
result <- x[ x$ranks <= 3 , ]

# look at your results
result
# and notice *both* cyl == 4 and ranks == 3 were included in your results
# because of the tie-breaking behavior chosen.

Here's my solution for Bootstrap 4:

<button id="search" class="btn btn-primary" 
data-loading-text="<i class='fa fa-spinner fa-spin fa-fw' aria-hidden='true'></i>Searching">
  Search
</button>

var setLoading = function () {
  var search = $('#search');
  if (!search.data('normal-text')) {
    search.data('normal-text', search.html());
  }
  search.html(search.data('loading-text'));
};

var clearLoading = function () {
  var search = $('#search');
  search.html(search.data('normal-text'));
};

setInterval(() => {
  setLoading();
  setTimeout(() => {
    clearLoading();
  }, 1000);
}, 2000);

gb = df.groupby(['A'])

gb_groups = grouped_df.groups

If you are looking for selective groupby objects then, do: gb_groups.keys(), and input desired key into the following key_list..

gb_groups.keys()

key_list = [key1, key2, key3 and so on...]

for key, values in gb_groups.iteritems():
    if key in key_list:
        print df.ix[values], "\n"

using :<line number> you can navigate to any line, thus :1 takes you to the first line.

I was trying to make my Angular app scroll to an anchor opon loading and ran into the URL rewriting rules of $routeProvider.

After long experimentation I settled on this:

1. register a document.onload event handler from the .run() section of the Angular app module.
2. in the handler find out what the original has anchor tag was supposed to be by doing some string operations.
3. override location.hash with the stripped down anchor tag (which causes $routeProvider to immediately overwrite it again with it's "#/" rule. But that is fine, because Angular is now in sync with what is going on in the URL 4) call $anchorScroll().

angular.module("bla",[]).}])_x000D_
.run(function($location, $anchorScroll){_x000D_
         $(document).ready(function() {_x000D_
  if(location.hash && location.hash.length>=1)      {_x000D_
   var path = location.hash;_x000D_
   var potentialAnchor = path.substring(path.lastIndexOf("/")+1);_x000D_
   if ($("#" + potentialAnchor).length > 0) {   // make sure this hashtag exists in the doc.                          _x000D_
       location.hash = potentialAnchor;_x000D_
       $anchorScroll();_x000D_
   }_x000D_
  }  _x000D_
 });

If you are using Windows command line to print the data, you should use

chcp 65001

This worked for me!

A logging script that I have written some time ago might be of help, although it is not exactly what you want. It acts in a way like a System.out.println but with much more information about StackTrace etc. It also provides Clickable text for Eclipse:

private static final SimpleDateFormat   extended    = new SimpleDateFormat( "dd MMM yyyy (HH:mm:ss) zz" );

public static java.util.logging.Logger initLogger(final String name) {
    final java.util.logging.Logger logger = java.util.logging.Logger.getLogger( name );
    try {

        Handler ch = new ConsoleHandler();
        logger.addHandler( ch );

        logger.setLevel( Level.ALL ); // Level selbst setzen

        logger.setUseParentHandlers( false );

        final java.util.logging.SimpleFormatter formatter = new SimpleFormatter() {

            @Override
            public synchronized String format(final LogRecord record) {
                StackTraceElement[] trace = new Throwable().getStackTrace();
                String clickable = "(" + trace[ 7 ].getFileName() + ":" + trace[ 7 ].getLineNumber() + ") ";
                /* Clickable text in Console. */

                for( int i = 8; i < trace.length; i++ ) {
                    /* 0 - 6 is the logging trace, 7 - x is the trace until log method was called */
                    if( trace[ i ].getFileName() == null )
                        continue;
                    clickable = "(" + trace[ i ].getFileName() + ":" + trace[ i ].getLineNumber() + ") -> " + clickable;
                }

                final String time = "<" + extended.format( new Date( record.getMillis() ) ) + "> ";

                StringBuilder level = new StringBuilder("[" + record.getLevel() + "] ");
                while( level.length() < 15 ) /* extend for tabby display */
                    level.append(" ");

                StringBuilder name = new StringBuilder(record.getLoggerName()).append(": ");
                while( name.length() < 15 ) /* extend for tabby display */
                    name.append(" ");

                String thread = Thread.currentThread().getName();
                if( thread.length() > 18 ) /* trim if too long */
                    thread = thread.substring( 0, 16 ) + "..."; 
                else {
                    StringBuilder sb = new StringBuilder(thread);
                    while( sb.length() < 18 ) /* extend for tabby display */
                        sb.append(" ");
                    thread = sb.insert( 0, "Thread " ).toString();
                }

                final String message = "\"" + record.getMessage() + "\" ";

                return level + time + thread + name + clickable + message + "\n";
            }
        };
        ch.setFormatter( formatter );
        ch.setLevel( Level.ALL );
    } catch( final SecurityException e ) {
        e.printStackTrace();
    }
    return logger;
}

Notice this outputs to the console, you can change that, see http://docs.oracle.com/javase/1.4.2/docs/api/java/util/logging/Logger.html for more information on that.

Now, the following will probably do what you want. It will go through all causes of a Throwable and save it in a String. Note that this does not use StringBuilder, so you can optimize by changing it.

Throwable e = ...
String detail = e.getClass().getName() + ": " + e.getMessage();
for( final StackTraceElement s : e.getStackTrace() )
    detail += "\n\t" + s.toString();
while( ( e = e.getCause() ) != null ) {
    detail += "\nCaused by: ";
    for( final StackTraceElement s : e.getStackTrace() )
        detail += "\n\t" + s.toString();
}

I've custom OAuth2 authorization and request.getHeader("Referer") is not available at poit of decision. But security request already saved in ExceptionTranslationFilter.sendStartAuthentication:

protected void sendStartAuthentication(HttpServletRequest request,...
    ...
    requestCache.saveRequest(request, response);

So, all what we need is share requestCache as Spring bean:

@Bean
public RequestCache requestCache() {
   return new HttpSessionRequestCache();
}

@Override
protected void configure(HttpSecurity http) throws Exception {
   http.authorizeRequests()
   ... 
   .requestCache().requestCache(requestCache()).and()
   ...
}     

and use it wheen authorization is finished:

@Autowired
private RequestCache requestCache;

public void authenticate(HttpServletRequest req, HttpServletResponse resp){
    ....
    SavedRequest savedRequest = requestCache.getRequest(req, resp);
    resp.sendRedirect(savedRequest != null && "GET".equals(savedRequest.getMethod()) ?  
    savedRequest.getRedirectUrl() : "defaultURL");
}

I'm using jquery datepicker to select date. My directive read date and convert it to json date format (in milliseconds) store in ng-model data while display formatted date.and reverse if ng-model have json date (in millisecond) my formatter display in my format as jquery datepicker.

Html Code:

<input type="text" jqdatepicker  ng-model="course.launchDate" required readonly />

Angular Directive:

myModule.directive('jqdatepicker', function ($filter) {
    return {
        restrict: 'A',
        require: 'ngModel',
         link: function (scope, element, attrs, ngModelCtrl) {
            element.datepicker({
                dateFormat: 'dd/mm/yy',
                onSelect: function (date) {   
                    var ar=date.split("/");
                    date=new Date(ar[2]+"-"+ar[1]+"-"+ar[0]);
                    ngModelCtrl.$setViewValue(date.getTime());            
                    scope.$apply();
                }
            });
            ngModelCtrl.$formatters.unshift(function(v) {
            return $filter('date')(v,'dd/MM/yyyy'); 
            });

        }
    };
});

In order to say how efficient it is to pair socks from a pile, we have to define the machine first, because the pairing isn't done whether by a turing nor by a random access machine, which are normally used as the basis for an algorithmic analysis.

The machine

The machine is an abstraction of a the real world element called human being. It is able to read from the environment via a pair of eyes. And our machine model is able to manipulate the environment by using 2 arms. Logical and arithmetic operations are calculated using our brain (hopefully ;-)).

We also have to consider the intrinsic runtime of the atomic operations that can be carried out with these instruments. Due to physical constraints, operations which are carried out by an arm or eye have non constant time complexity. This is because we can't move an endlessly large pile of socks with an arm nor can an eye see the top sock on an endlessly large pile of socks.

However mechanical physics give us some goodies as well. We are not limited to move at most one sock with an arm. We can move a whole couple of them at once.

So depending on the previous analysis following operations should be used in descending order:

• logical and arithmetic operations
• environmental reads
• environmental modifications

We can also make use of the fact that people only have a very limited amount of socks. So an environmental modification can involve all socks in the pile.

The algorithm

So here is my suggestion:

1. Spread all socks in the pile over the floor.
2. Find a pair by looking at the socks on the floor.
3. Repeat from 2 until no pair can be made.
4. Repeat from 1 until there are no socks on the floor.

Operation 4 is necessary, because when spreading socks over the floor some socks may hide others. Here is the analysis of the algorithm:

The analysis

The algorithm terminates with high probability. This is due to the fact that one is unable to find pairs of socks in step number 2.

For the following runtime analysis of pairing n pairs of socks, we suppose that at least half of the 2n socks aren't hidden after step 1. So in the average case we can find n/2 pairs. This means that the loop is step 4 is executed O(log n) times. Step 2 is executed O(n^2) times. So we can conclude:

• The algorithm involves O(ln n + n) environmental modifications (step 1 O(ln n) plus picking every pair of sock from the floor)
• The algorithm involves O(n^2) environmental reads from step 2
• The algorithm involves O(n^2) logical and arithmetic operations for comparing a sock with another in step 2

So we have a total runtime complexity of O(r*n^2 + w*(ln n + n)) where r and w are the factors for environmental read and environmental write operations respectively for a reasonable amount of socks. The cost of the logical and arithmetical operations are omitted, because we suppose that it takes a constant amount of logical and arithmetical operations to decide whether 2 socks belong to the same pair. This may not be feasible in every scenario.

For Bootstrap v4 use:
has-danger for form-group wrapper,
form-control-danger for input to show icon (will display ? at the end of input),
form-control-feedback to message wrapper

You have VisualTkinter also known as Visual Python. Development seems not active. You have sourceforge and googlecode sites. Web site is here.

On the other hand, you have PAGE that seems active and works in python 2.7 and py3k

As you indicate on your comment, none of these use the grid geometry. As far as I can say the only GUI builder doing that could probably be Komodo Pro GUI Builder which was discontinued and made open source in ca. 2007. The code was located in the SpecTcl repository.

It seems to install fine on win7 although has not used it yet. This is an screenshot from my PC:

By the way, Rapyd Tk also had plans to implement grid geometry as in its documentation says it is not ready 'yet'. Unfortunately it seems 'nearly' abandoned.

You can get the coordinate of the target element and set the scroll position to it. But this is so complicated.

Here is a lazier way to do that:

function jump(h){
    var url = location.href;               //Save down the URL without hash.
    location.href = "#"+h;                 //Go to the target element.
    history.replaceState(null,null,url);   //Don't like hashes. Changing it back.
}

This uses replaceState to manipulate the url. If you also want support for IE, then you will have to do it the complicated way:

function jump(h){
    var top = document.getElementById(h).offsetTop; //Getting Y of target element
    window.scrollTo(0, top);                        //Go there directly or some transition
}?

Demo: http://jsfiddle.net/DerekL/rEpPA/
Another one w/ transition: http://jsfiddle.net/DerekL/x3edvp4t/

You can also use .scrollIntoView:

document.getElementById(h).scrollIntoView();   //Even IE6 supports this

_{(Well I lied. It's not complicated at all.)}

All you are wanting to do is to see if computers are connected to the network and to gather their IP addresses. You can utilize angryIP scanner: http://angryip.org/ to see what IP addresses are in use on a particular subnet or groups of subnets.

I have found this tool very helpful when trying to see what IPs are being used that are not located inside of my DHCP.

The definition of optimal can vary, but here's how to concatenate strings from different rows using regular Transact SQL, which should work fine in Azure.

;WITH Partitioned AS

        NameCount 
    FROM Partitioned 
    WHERE NameNumber = 1

    UNION ALL

    SELECT 
        P.ID, 
        CAST(C.FullName + ', ' + P.Name AS nvarchar), 
        P.Name, 
        P.NameNumber, 
        P.NameCount
    FROM Partitioned AS P
        INNER JOIN Concatenated AS C 
                ON P.ID = C.ID 
                AND P.NameNumber = C.NameNumber + 1
)
SELECT 
    ID,
    FullName
FROM Concatenated
WHERE NameNumber = NameCount

EXPLANATION

The approach boils down to three steps:

1. Number the rows using OVER and PARTITION grouping and ordering them as needed for the concatenation. The result is Partitioned CTE. We keep counts of rows in each partition to filter the results later.

2. Using recursive CTE (Concatenated) iterate through the row numbers (NameNumber column) adding Name values to FullName column.

3. Filter out all results but the ones with the highest NameNumber.

Please keep in mind that in order to make this query predictable one has to define both grouping (for example, in your scenario rows with the same ID are concatenated) and sorting (I assumed that you simply sort the string alphabetically before concatenation).

I've quickly tested the solution on SQL Server 2012 with the following data:

INSERT dbo.SourceTable (ID, Name)
VALUES 
(1, 'Matt'),
(1, 'Rocks'),
(2, 'Stylus'),
(3, 'Foo'),
(3, 'Bar'),
(3, 'Baz')

The query result:

ID          FullName
----------- ------------------------------
2           Stylus
3           Bar, Baz, Foo
1           Matt, Rocks

This is because width when provided a % doesn't account for padding/margins. You will need to reduce the amount to possibly 24% or 24.5%. Once this is done you should be good, but you will need to provide different options based on the screen size if you want this to always work correct since you have a hardcoded margin, but a relative size.

If you wanted a looser criterion for rejection, for example, to reject empty strings as well as nil, you could use:

[1, nil, 3, 0, ''].reject(&:blank?)
 => [1, 3, 0] 

If you wanted to go further and reject zero values (or apply more complex logic to the process), you could pass a block to reject:

[1, nil, 3, 0, ''].reject do |value| value.blank? || value==0 end
 => [1, 3]

[1, nil, 3, 0, '', 1000].reject do |value| value.blank? || value==0 || value>10 end
 => [1, 3]

How about:

d = d.applymap(lambda x: np.nan if isinstance(x, basestring) and x.isspace() else x)

The applymap function applies a function to every cell of the dataframe.

colorRampPalette could be your friend here:

colfunc <- colorRampPalette(c("black", "white"))
colfunc(10)
# [1] "#000000" "#1C1C1C" "#383838" "#555555" "#717171" "#8D8D8D" "#AAAAAA"
# [8] "#C6C6C6" "#E2E2E2" "#FFFFFF"

And just to show it works:

plot(rep(1,10),col=colfunc(10),pch=19,cex=3)

If you are using Facebook SDK, you don't need to bother yourself to enter anything for redirect URI on the app management page of facebook. Just setup a URL scheme for your iOS app. The URL scheme of your app should be a value "fbxxxxxxxxxxx" where xxxxxxxxxxx is your app id as identified on facebook. To setup URL scheme for your iOS app, go to info tab of your app settings and add URL Type.

try with sticky jquery plugin

Another example with a struct :

package types

import "fmt"

type MyType struct {
    Id   int    
    Name string
}

func (t MyType) String() string {
    return fmt.Sprintf(
    "[%d : %s]",
    t.Id, 
    t.Name)
}

Be careful when using it,
concatenation with '+' doesn't compile :

t := types.MyType{ 12, "Blabla" }

fmt.Println(t) // OK
fmt.Printf("t : %s \n", t) // OK
//fmt.Println("t : " + t) // Compiler error !!!
fmt.Println("t : " + t.String()) // OK if calling the function explicitly

simple

int MAX = 3;

int count = 0;
while (true) {
    try {
        ...

        break;
    } catch (Exception e) {
        if (count++ < MAX) {
            continue;
        }

        ...
        
        break;
    }
}

In Chrome, there is "Task Manager", accessible via Shift+ESC or through

Menu → More Tools → Task Manager

You can select your page task and end it by pressing "End Process" button.

If using Windows and Powershell, you can use the following to delete all local branches that have been merged into the branch currently checked out:

git branch --merged | ? {$_[0] -ne '*'} | % {$_.trim()} | % {git branch -d $_}

Explanation

• Lists the current branch and the branches that have been merged into it
• Filters out the current branch
• Cleans up any leading or trailing spaces from the git output for each remaining branch name
• Deletes the merged local branches

It's worth running git branch --merged by itself first just to make sure it's only going to remove what you expect it to.

I think you should check the following project at codeplex.com http://autoupdater.codeplex.com/

This sample application is developed in C# as a library with the project name “AutoUpdater”. The DLL “AutoUpdater” can be used in a C# Windows application(WinForm and WPF).

There are certain features about the AutoUpdater:

1. Easy to implement and use.
2. Application automatic re-run after checking update.
3. Update process transparent to the user.
4. To avoid blocking the main thread using multi-threaded download.
5. Ability to upgrade the system and also the auto update program.
6. A code that doesn't need change when used by different systems and could be compiled in a library.
7. Easy for user to download the update files.

How to use?

In the program that you want to be auto updateable, you just need to call the AutoUpdate function in the Main procedure. The AutoUpdate function will check the version with the one read from a file located in a Web Site/FTP. If the program version is lower than the one read the program downloads the auto update program and launches it and the function returns True, which means that an auto update will run and the current program should be closed. The auto update program receives several parameters from the program to be updated and performs the auto update necessary and after that launches the updated system.

  #region check and download new version program
  bool bSuccess = false;
  IAutoUpdater autoUpdater = new AutoUpdater();
  try
  {
      autoUpdater.Update();
      bSuccess = true;
  }
  catch (WebException exp)
  {
      MessageBox.Show("Can not find the specified resource");
  }
  catch (XmlException exp)
  {
      MessageBox.Show("Download the upgrade file error");
  }
  catch (NotSupportedException exp)
  {
      MessageBox.Show("Upgrade address configuration error");
  }
  catch (ArgumentException exp)
  {
      MessageBox.Show("Download the upgrade file error");
  }
  catch (Exception exp)
  {
      MessageBox.Show("An error occurred during the upgrade process");
  }
  finally
  {
      if (bSuccess == false)
      {
          try
          {
              autoUpdater.RollBack();
          }
          catch (Exception)
          {
             //Log the message to your file or database
          }
      }
  }
  #endregion

Okay, so if later on down the line the issue is that you have a query that's greater than the allowable size (which may happen if it keeps growing) you're going to have to break it into chunks and execute the string values. So, let's say you have a stored procedure like the following:

CREATE PROCEDURE ExecuteMyHugeQuery
    @SQL VARCHAR(MAX) -- 2GB size limit as stated by Martin Smith
AS
BEGIN
    -- Now, if the length is greater than some arbitrary value
    -- Let's say 2000 for this example
    -- Let's chunk it
    -- Let's also assume we won't allow anything larger than 8000 total
    DECLARE @len INT
    SELECT @len = LEN(@SQL)

    IF (@len > 8000)
    BEGIN
        RAISERROR ('The query cannot be larger than 8000 characters total.',
                   16,
                   1);
    END

    -- Let's declare our possible chunks
    DECLARE @Chunk1 VARCHAR(2000),
            @Chunk2 VARCHAR(2000),
            @Chunk3 VARCHAR(2000),
            @Chunk4 VARCHAR(2000)

    SELECT @Chunk1 = '',
           @Chunk2 = '',
           @Chunk3 = '',
           @Chunk4 = ''

    IF (@len > 2000)
    BEGIN
        -- Let's set the right chunks
        -- We already know we need two chunks so let's set the first
        SELECT @Chunk1 = SUBSTRING(@SQL, 1, 2000)

        -- Let's see if we need three chunks
        IF (@len > 4000)
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, 2000)

            -- Let's see if we need four chunks
            IF (@len > 6000)
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, 2000)
                SELECT @Chunk4 = SUBSTRING(@SQL, 6001, (@len - 6001))
            END
              ELSE
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, (@len - 4001))
            END
        END
          ELSE
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, (@len - 2001))
        END
    END

    -- Alright, now that we've broken it down, let's execute it
    EXEC (@Chunk1 + @Chunk2 + @Chunk3 + @Chunk4)
END

The problem comes in by me not knowing how to send a unique identifier with an ng-click to only expand/collapse the right content.

You can pass $event with ng-click (ng-dblclick, and ng- mouse events), then you can determine which element caused the event:

<a ng-click="doSomething($event)">do something</a>

Controller:

$scope.doSomething = function(ev) {
    var element = ev.srcElement ? ev.srcElement : ev.target;
    console.log(element, angular.element(element))
    ...
}

Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.

The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.

delimiter //

  create procedure myPivot(
    in tableA varchar(255),
    in columnA varchar(255),
    in tableB varchar(255),
    in columnB varchar(255)
)
begin
  set @sql = NULL;
    set @sql = CONCAT('select group_concat(distinct concat(
            \'SUM(IF(', 
        columnA, 
        ' = \'\'\',',
        columnA,
        ',\'\'\', 1, 0)) AS \'\'\',',
        columnA, 
            ',\'\'\'\') separator \', \') from ',
        tableA, ' into @sql');
    -- select @sql;

    PREPARE stmt FROM @sql;
    EXECUTE stmt;

    DEALLOCATE PREPARE stmt;
    -- select @sql;

    SET @sql = CONCAT('SELECT p.', 
        columnB, 
        ', ', 
        @sql, 
        ' FROM ', tableB, ' p GROUP BY p.',
        columnB,'');

I experienced the same problem and tried most of the resolutions above. Simply deleting cache and temp files end up working for me.

Try removing the contents of these two folders:

C:\Users\\{UserName}\AppData\Local\Microsoft\WebsiteCache

and

C:\Users\\{UserName}\AppData\Local\Temp (in particular the iisexpress and Temporary ASP.NET Files folders).

This can be set up to happen automatically on logging on to Windows by adding a cmd file to the C:\Users\\{username}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup folder with the following content:

rmdir C:\Users\\{username}\AppData\Local\Microsoft\WebsiteCache /s /q

rmdir C:\Users\\{username}\AppData\Local\Temp /s /q

I am not going to give you the whole answer (I don't think you're looking for the parsing and writing to file part anyway), but a pivotal hint should suffice: use python's set() function, and then sorted() or .sort() coupled with .reverse():

>>> a=sorted(set([10,60,30,10,50,20,60,50,60,10,30]))
>>> a
[10, 20, 30, 50, 60]
>>> a.reverse()
>>> a
[60, 50, 30, 20, 10]

Here is my solution:

#include <stdexcept>
#include <sstream>

class Formatter
{
public:
    Formatter() {}
    ~Formatter() {}

    template <typename Type>
    Formatter & operator << (const Type & value)
    {
        stream_ << value;
        return *this;
    }

    std::string str() const         { return stream_.str(); }
    operator std::string () const   { return stream_.str(); }

    enum ConvertToString 
    {
        to_str
    };
    std::string operator >> (ConvertToString) { return stream_.str(); }

private:
    std::stringstream stream_;

    Formatter(const Formatter &);
    Formatter & operator = (Formatter &);
};

Example:

throw std::runtime_error(Formatter() << foo << 13 << ", bar" << myData);   // implicitly cast to std::string
throw std::runtime_error(Formatter() << foo << 13 << ", bar" << myData >> Formatter::to_str);    // explicitly cast to std::string

Regex is not on the list of search features, and it was on (more or less, as Better message search functionality (i.e. Wildcard and partial word search)) the list of pre-canned feature requests, so the answer is "you cannot do this via the Gmail web UI" :-(

There are no current Labs features which offer this. SIEVE filters would be another way to do this, that too was not supported, there seems to no longer be any definitive statement on SIEVE support in the Gmail help.

Updated for link rot The pre-canned list of feature requests was, er canned, the original is on archive.org dated 2012, now you just get redirected to a dumbed down page telling you how to give feedback. Lack of SIEVE support was covered in answer 78761 Does Gmail support all IMAP features?, since some time in 2015 that answer silently redirects to the answer about IMAP client configuration, archive.org has a copy dated 2014.

With the current search facility brackets of any form () {} [] are used for grouping, they have no observable effect if there's just one term within. Using (aaa|bbb) and [aaa|bbb] are equivalent and will both find words aaa or bbb. Most other punctuation characters, including \, are treated as a space or a word-separator, + - : and " do have special meaning though, see the help.

As of 2016, only the form "{term1 term2}" is documented for this, and is equivalent to the search "term1 OR term2".

You can do regex searches on your mailbox (within limits) programmatically via Google docs: http://www.labnol.org/internet/advanced-gmail-search/21623/ has source showing how it can be done (copy the document, then Tools > Script Editor to get the complete source).

You could also do this via IMAP as described here: Python IMAP search for partial subject and script something to move messages to different folder. The IMAP SEARCH verb only supports substrings, not regex (Gmail search is further limited to complete words, not substrings), further processing of the matches to apply a regex would be needed.

For completeness, one last workaround is: Gmail supports plus addressing, if you can change the destination address to [email protected] it will still be sent to your mailbox where you can filter by recipient address. Make sure to filter using the full email address to:[email protected]. This is of course more or less the same thing as setting up a dedicated Gmail address for this purpose :-)

Maybe .value_counts()?

>>> import pandas
>>> my_series = pandas.Series([1,2,2,3,3,3, "fred", 1.8, 1.8])
>>> my_series

1       2
2       2
3       3
4       3
5       3
6    fred
7     1.8
8     1.8
>>> counts = my_series.value_counts()
>>> counts

2       2
1.8     2
fred    1

{1.8: 2, 2: 2, 3: 3, 1: 1, 'fred': 1}

You have to download the font file and load it in your CSS.

F.e. I'm using the Yanone Kaffeesatz font in my Web Application.

I load and use it via

@font-face {
    font-family: "Yanone Kaffeesatz";
    src: url("../fonts/YanoneKaffeesatz-Regular.ttf");
}

in my stylesheet.

import random
import time
import sys
while True:
    x=random.randint(1,100)
    print('''Guess my number--it's from 1 to 100.''')
    z=0
    while True:
        z=z+1
        xx=int(str(sys.stdin.readline()))
        if xx > x:
            print("Too High!")
        elif xx < x:
            print("Too Low!")
        elif xx==x:
            print("You Win!! You used %s guesses!"%(z))
            print()
            break
        else:
            break

in this, I first string the number str(), which converts it into an inoperable number. Then, I int() integerize it, to make it an operable number. I just tested your problem on my IDLE GUI, and it said that 49.8 < 50.

For texts in angular template (userType is property of $scope, like $scope.userType):

<span>
  {{userType=='admin' ? 'Edit' : 'Show'}}
</span>

This link says it better than I could and helped in my decision making. I usually opt for an int as a primary key, unless I have a specific need not to and I also let SQL server auto-generate/maintain this field unless I have some specific reason not to. In reality, performance concerns need to be determined based on your specific app. There are many factors at play here including but not limited to expected db size, proper indexing, efficient querying, and more. Although people may disagree, I think in many scenarios you will not notice a difference with either option and you should choose what is more appropriate for your app and what allows you to develop easier, quicker, and more effectively (If you never complete the app what difference does the rest make :).

https://web.archive.org/web/20120812080710/http://databases.aspfaq.com/database/what-should-i-choose-for-my-primary-key.html

P.S. I'm not sure why you would use a Composite PK or what benefit you believe that would give you.

If you like HTML tags more than markdown + center alignment:

<div align="center">_x000D_
  <a href="https://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE"><img src="https://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg" alt="IMAGE ALT TEXT"></a>_x000D_
</div>

You could make usage of Array.prototype.indexOf. For that, we need to somewhat "cast" the HTMLNodeCollection into a true Array. For instance:

var nodes = Array.prototype.slice.call( document.getElementById('list').children );

Then we could just call:

nodes.indexOf( liNodeReference );

Example:

var nodes = Array.prototype.slice.call( document.getElementById('list').children ),_x000D_
    liRef = document.getElementsByClassName('match')[0];_x000D_
_x000D_
console.log( nodes.indexOf( liRef ) );

<ul id="list">_x000D_
    <li>foo</li>_x000D_
    <li class="match">bar</li>_x000D_
    <li>baz</li>    _x000D_
</ul>

If you want to authenticate against a user name and password and without an authorization cookie, the MVC4 Authorize attribute won't work out of the box. However, you can add the following helper method to your controller to accept basic authentication headers. Call it from the beginning of your controller's methods.

void EnsureAuthenticated(string role)
{
    string[] parts = UTF8Encoding.UTF8.GetString(Convert.FromBase64String(Request.Headers.Authorization.Parameter)).Split(':');
    if (parts.Length != 2 || !Membership.ValidateUser(parts[0], parts[1]))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "No account with that username and password"));
    if (role != null && !Roles.IsUserInRole(parts[0], role))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "An administrator account is required"));
}

From the client side, this helper creates a HttpClient with the authentication header in place:

static HttpClient CreateBasicAuthenticationHttpClient(string userName, string password)
{
    var client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(userName + ':' + password)));
    return client;
}

I guess what you're looking for is pyquery:

pyquery: a jquery-like library for python.

An example of what you want may be like:

from pyquery import PyQuery    
html = # Your HTML CODE
pq = PyQuery(html)
tag = pq('div#id') # or     tag = pq('div.class')
print tag.text()

And it uses the same selectors as Firefox's or Chrome's inspect element. For example:

The inspected element selector is 'div#mw-head.noprint'. So in pyquery, you just need to pass this selector:

pq('div#mw-head.noprint')

Apparently xerces:xml-apis:1.4.01 is no longer in maven central, which is however what xerces:xercesImpl:2.11.0 references.

This works for me:

<dependency>
  <groupId>xerces</groupId>
  <artifactId>xercesImpl</artifactId>
  <version>2.11.0</version>
  <exclusions>
    <exclusion>
      <groupId>xerces</groupId>
      <artifactId>xml-apis</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>xml-apis</groupId>
  <artifactId>xml-apis</artifactId>
  <version>1.4.01</version>

Use this:

var dict = list.ToDictionary(x => x);

See MSDN for more info.

As Pranay points out in the comments, this will fail if an item exists in the list multiple times.
Depending on your specific requirements, you can either use var dict = list.Distinct().ToDictionary(x => x); to get a dictionary of distinct items or you can use ToLookup instead:

var dict = list.ToLookup(x => x);

This will return an ILookup<string, string> which is essentially the same as IDictionary<string, IEnumerable<string>>, so you will have a list of distinct keys with each string instance under it.

REST may not be a standard as such, but reading up on general REST documentation and blog posts should give you some guidelines for a good way to structure API URLs. Most rest APIs tend to only have resource names and resource IDs in the path. Such as:

/departments/{dept}/employees/{id}

Some REST APIs use query strings for filtering, pagination and sorting, but Since REST isn't a strict standard I'd recommend checking some REST APIs out there such as github and stackoverflow and see what could work well for your use case.

I'd recommend putting any required parameters in the path, and any optional parameters should certainly be query string parameters. Putting optional parameters in the path will end up getting really messy when trying to write URL handlers that match different combinations.

document.querySelectorAll() has several inconsistencies across browsers and is not supported in older browsers^{This probably won't cause any trouble anymore nowadays}. It has a very unintuitive scoping mechanism and some other not so nice features. Also with javascript you have a harder time working with the result sets of these queries, which in many cases you might want to do. jQuery provides functions to work on them like: filter(), find(), children(), parent(), map(), not() and several more. Not to mention the jQuery ability to work with pseudo-class selectors.

However, I would not consider these things as jQuery's strongest features but other things like "working" on the dom (events, styling, animation & manipulation) in a crossbrowser compatible way or the ajax interface.

If you only want the selector engine from jQuery you can use the one jQuery itself is using: Sizzle That way you have the power of jQuerys Selector engine without the nasty overhead.

EDIT: Just for the record, I'm a huge vanilla JavaScript fan. Nonetheless it's a fact that you sometimes need 10 lines of JavaScript where you would write 1 line jQuery.

Of course you have to be disciplined to not write jQuery like this:

$('ul.first').find('.foo').css('background-color', 'red').end().find('.bar').css('background-color', 'green').end();

This is extremely hard to read, while the latter is pretty clear:

$('ul.first')
   .find('.foo')
      .css('background-color', 'red')
.end()
   .find('.bar')
      .css('background-color', 'green')
.end();

The equivalent JavaScript would be far more complex illustrated by the pseudocode above:

1) Find the element, consider taking all element or only the first.

// $('ul.first')
// taking querySelectorAll has to be considered
var e = document.querySelector("ul.first");

2) Iterate over the array of child nodes via some (possibly nested or recursive) loops and check the class (classlist not available in all browsers!)

//.find('.foo')
for (var i = 0;i<e.length;i++){
     // older browser don't have element.classList -> even more complex
     e[i].children.classList.contains('foo');
     // do some more magic stuff here
}

3) apply the css style

// .css('background-color', 'green')
// note different notation
element.style.backgroundColor = "green" // or
element.style["background-color"] = "green"

This code would be at least two times as much lines of code you write with jQuery. Also you would have to consider cross-browser issues which will compromise the severe speed advantage (besides from the reliability) of the native code.

I think every edge has been considered twice and every node has been visited once, so the total time complexity should be O(2E+V).

There is a doc for that

https://docs.djangoproject.com/en/dev/topics/http/urls/#reverse-resolution-of-urls

it can be used to generate an URL for a given view

main advantage is that you do not hard code routes in your code.

edit: I guess it's now starting to be safe to use the native JSON.stringify() method, supported by most browsers (yes, even IE8+ if you're wondering).

As simple as:

JSON.stringify(yourData)

You should encode you data in JSON before sending it, you can't just send an object like this as POST data.

I recommand using the jQuery json plugin to do so. You can then use something like this in jQuery:

$.post(_saveDeviceUrl, {
    data : $.toJSON(postData)
}, function(response){
    //Process your response here
}
);

If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:

var items = (from x in parameters
                join y in myStrings on x.Source equals y
                select x)
            .ToList();

Some online API's work pretty well: ocr.space and Google Cloud Vision. Both of these are free, as long as you do less than 1000 OCR's per month. You can drag & drop an image to do a quick manual test to see how they perform for your images.

I find OCR.space easier to use (no messing around with nuget libraries), but, for my purpose, Google Cloud Vision provided slightly better results than OCR.space.

Google Cloud Vision example:

GoogleCredential cred = GoogleCredential.FromJson(json);
Channel channel = new Channel(ImageAnnotatorClient.DefaultEndpoint.Host, ImageAnnotatorClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
ImageAnnotatorClient client = ImageAnnotatorClient.Create(channel);
Image image = Image.FromStream(stream);

EntityAnnotation googleOcrText = client.DetectText(image).First();
Console.Write(googleOcrText.Description);

OCR.space example:

string uri = $"https://api.ocr.space/parse/imageurl?apikey=helloworld&url={imageUri}";
string responseString = WebUtilities.DoGetRequest(uri);
OcrSpaceResult result = JsonConvert.DeserializeObject<OcrSpaceResult>(responseString);
if ((!result.IsErroredOnProcessing) && !String.IsNullOrEmpty(result.ParsedResults[0].ParsedText))
  return result.ParsedResults[0].ParsedText;

To quote the help page (try ?integer), bolded portion mine:

Integer vectors exist so that data can be passed to C or Fortran code which expects them, and so that (small) integer data can be represented exactly and compactly.

Note that current implementations of R use 32-bit integers for integer vectors, so the range of representable integers is restricted to about +/-2*10^9: doubles can hold much larger integers exactly.

Like the help page says, R's integers are signed 32-bit numbers so can hold between -2147483648 and +2147483647 and take up 4 bytes.

R's numeric is identical to an 64-bit double conforming to the IEEE 754 standard. R has no single precision data type. (source: help pages of numeric and double). A double can store all integers between -2^53 and 2^53 exactly without losing precision.

We can see the data type sizes, including the overhead of a vector (source):

> object.size(1:1000)
4040 bytes
> object.size(as.numeric(1:1000))
8040 bytes

Queue is in the multiprocessing module so:

from multiprocessing import Queue

If you are starting the script within the command line, then add exit /b to keep CMD opened

If you're looking to post data to a URL from PHP code itself (without using an html form) it can be done with curl. It will look like this:

$url = 'http://www.someurl.com';
$myvars = 'myvar1=' . $myvar1 . '&myvar2=' . $myvar2;

$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $myvars);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec( $ch );

This will send the post variables to the specified url, and what the page returns will be in $response.

Like what Volker mentioned, nested structs is the way to go. But if you really do not want nested structs, you can override the UnmarshalJSON func.

https://play.golang.org/p/dqn5UdqFfJt

type A struct {
    FooBar string // takes foo.bar
    FooBaz string // takes foo.baz
    More   string 
}

func (a *A) UnmarshalJSON(b []byte) error {

    var f interface{}
    json.Unmarshal(b, &f)

    m := f.(map[string]interface{})

    foomap := m["foo"]
    v := foomap.(map[string]interface{})

    a.FooBar = v["bar"].(string)
    a.FooBaz = v["baz"].(string)
    a.More = m["more"].(string)

    return nil
}

Please ignore the fact that I'm not returning a proper error. I left that out for simplicity.

UPDATE: Correctly retrieving "more" value.

You might use flush to force validation constraints to be realised and detected in a known place rather than when the transaction is committed. It may be that commit gets called implicitly by some framework logic, through declarative logic, the container, or by a template. In this case, any exception thrown may be difficult to catch and handle (it could be too high in the code).

For example, if you save() a new EmailAddress object, which has a unique constraint on the address, you won't get an error until you commit.

Calling flush() forces the row to be inserted, throwing an Exception if there is a duplicate.

However, you will have to roll back the session after the exception.

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

Regarding git fetch -p, its behavior changed in Git 1.9, and only Git 2.9.x/2.10 reflects that.

See commit 9e70233 (13 Jun 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 1c22105, 06 Jul 2016)}

fetch: document that pruning happens before fetching

This was changed in 10a6cc8 (fetch --prune: Run prune before fetching, 2014-01-02), but it seems that nobody in that discussion realized we were advertising the "after" explicitly.

So the documentation now states:

Before fetching, remove any remote-tracking references that no longer exist on the remote

That is because:

When we have a remote-tracking branch named "frotz/nitfol" from a previous fetch, and the upstream now has a branch named "frotz", fetch would fail to remove "frotz/nitfol" with a "git fetch --prune" from the upstream. git would inform the user to use "git remote prune" to fix the problem.

Change the way "fetch --prune" works by moving the pruning operation before the fetching operation. This way, instead of warning the user of a conflict, it automatically fixes it.

1. Go to the remote host (e.g., https://github.com/<User>/<Project>/ ).
2. Click tab Settings.
3. Rename under Repository name (and press button Rename).

INSERT INTO destination_table ( 
      Field_1, 
      Field_2, 
      Field_3) 
SELECT Field_1, 
      Field_2, 
      Field_3 
      FROM source_table;

BUT this is a BAD MYSQL

Do this instead:

1. drop the destination table: DROP DESTINATION_TABLE;
2. CREATE TABLE DESTINATION_TABLE AS (SELECT * FROM SOURCE_TABLE);

I could not find a prohibition in writing, but by convention, the Windows hosts file closely follows the UNIX hosts file, and you cannot put wildcard hostname references into that file.

If you read the man page, it says:

DESCRIPTION
     The hosts file contains information regarding the known hosts on the net-
     work.  For each host a single line should be present with the following
     information:

           Internet address
           Official host name
           Aliases

Although it does say,

     Host names may contain any printable character other than a field delim-
     iter, newline, or comment character.

that is not true from a practical level.

Basically, the code that looks at the /etc/hosts file does not support a wildcard entry.

The workaround is to create all the entries in advance, maybe use a script to put a couple hundred entries at once.

This solution is for Litespeed Server (Apache as well)

Add the following code in .htaccess

RewriteRule .* - [E=noabort:1]
RewriteRule .* - [E=noconntimeout:1]

var xhr = new XMLHttpRequest();
xhr.open("POST", "Reporting.jsp"); //url.It can pdf file path
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.responseType = "blob";
xhr.onload = function () {
    if (this.status === 200) {
        var blob = new Blob([xhr.response]);
        const url = window.URL.createObjectURL(blob);
        var a = document.createElement('a');
        a.href = url;
        a.download = 'myFile.pdf';
        a.click();
        setTimeout(function () {
            // For Firefox it is necessary to delay revoking the ObjectURL
            window.URL.revokeObjectURL(data)

        })
    }
};
xhr.send(data);

The compilation problem only occurs for me (gcc 4.3, ubuntu 8.10) if the three variables are global. The problem is that C doesn't work like a script languages, so you cannot take for granted that the initialization of u and t occur after the one of s. That's why you get a compilation error. Now, you cannot initialize t and y they way you did it before, that's why you will need a char*. The code that do the work is the following:

#include <stdio.h>
#include <stdlib.h>

#define STR "ABCD"

const char s[] = STR;
char* t;
char* u;

void init(){
    t = malloc(sizeof(STR)-1);
    t[0] = s[0];
    t[1] = s[1];
    t[2] = s[2];
    t[3] = s[3];


    u = malloc(sizeof(STR)-1);
    u[0] = s[3];
    u[1] = s[2];
    u[2] = s[1];
    u[3] = s[0];
}

int main(void) {
    init();
    puts(t);
    puts(u);

    return EXIT_SUCCESS;
}

I have a nice simple lib here that allows you to use sealed traits/classes as enum values without having to maintain your own list of values. It relies on a simple macro that is not dependent on the buggy knownDirectSubclasses.

This is a textbook case for a constructor function:

var myArray = [];

function myElement(id, value){
    this.id = id
    this.value = value
}

myArray[0] = new myElement(0,1)
myArray[1] = new myElement(2,3)
// or myArray.push(new myElement(1, 1))

Try adding the following to your InventoryApp class

@SpringBootApplication
@ComponentScan(basePackageClasses = ItemInventoryController.class)
public class InventoryApp {
...

spring-boot will scan for components in packages below com.nice.application, so if your controller is in com.nice.controller you need to scan for it explicitly.

Sometime missing "jasmine" from tsconfig.json may cause this error. (TypeScript 2.X)

to your tsconfig.json file.

i made a method that merge cells and put border.

protected void setMerge(Sheet sheet, int numRow, int untilRow, int numCol, int untilCol, boolean border) {
    CellRangeAddress cellMerge = new CellRangeAddress(numRow, untilRow, numCol, untilCol);
    sheet.addMergedRegion(cellMerge);
    if (border) {
        setBordersToMergedCells(sheet, cellMerge);
    }

}



protected void setBordersToMergedCells(Sheet sheet, CellRangeAddress rangeAddress) {
    RegionUtil.setBorderTop(BorderStyle.MEDIUM, rangeAddress, sheet);

    RegionUtil.setBorderRight(BorderStyle.MEDIUM, rangeAddress, sheet);
    RegionUtil.setBorderBottom(BorderStyle.MEDIUM, rangeAddress, sheet);
}

Here's a way to combining string, wstring and mixed string constants to wstring. Use the wstringstream class.

This does NOT work for multi-byte character encodings. This is just a dumb way of throwing away type safety and expanding 7 bit characters from std::string into the lower 7 bits of each character of std:wstring. This is only useful if you have a 7-bit ASCII strings and you need to call an API that requires wide strings.

#include <sstream>

std::string narrow = "narrow";
std::wstring wide = L"wide";

std::wstringstream cls;
cls << " abc " << narrow.c_str() << L" def " << wide.c_str();
std::wstring total= cls.str();

if you want to find index for more than 2 occurrence:

public static int ordinalIndexOf(String fullText,String subText,int pos){

    if(fullText.contains(subText)){
        if(pos <= 1){
            return fullText.indexOf(subText);
        }else{
            --pos;
            return fullText.indexOf(subText, ( ordinalIndexOf(fullText,subText,pos) + 1) );
        }
    }else{
        return -1;
    }

}

Another option is Apache Commons Config also has a class for loading from INI files. It does have some runtime dependencies, but for INI files it should only require Commons collections, lang, and logging.

I've used Commons Config on projects with their properties and XML configurations. It is very easy to use and supports some pretty powerful features.

You can also simply do

session.setConfig("StrictHostKeyChecking", "no");

It's not secure and it's a workaround not suitable for live environment as it will disable globally known host keys checking.

Best and most generic way to control the music is to create a mother Activity in which you override startActivity(Intent intent) - in it you put shouldPlay=true, and onBackPressed() - in it you put shouldPlay = true. onStop - in it you put a conditional mediaPlayer.stop with shouldPlay as condition

Then, just extend the mother activity to all other activities, and no code duplicating is needed.

W3Schools recommendation:

put overflow: auto on parent element and it will "color" whole background including elements margins. Also floating elements will stay inside of border.

In python, integers and strings are immutable and are passed by value. You cannot pass a string, or integer, to a function and expect the argument to be modified.

So to convert string limit="100" to a number, you need to do

limit = int(limit) # will return new object (integer) and assign to "limit"

If you really want to go around it, you can use a list. Lists are mutable in python; when you pass a list, you pass it's reference, not copy. So you could do:

def int_in_place(mutable):
    mutable[0] = int(mutable[0])

mutable = ["1000"]
int_in_place(mutable)
# now mutable is a list with a single integer

But you should not need it really. (maybe sometimes when you work with recursions and need to pass some mutable state).

You had several issues with your code.

1) Missing a closing brace, }, within your rules.

2) In this case, there is no reason to use a function for the required rule. By default, the plugin can handle checkbox and radio inputs just fine, so using true is enough. However, this will simply do the same logic as in your original function and verify that at least one is checked.

3) If you also want only a maximum of two to be checked, then you'll need to apply the maxlength rule.

4) The messages option was missing the rule specification. It will work, but the one custom message would apply to all rules on the same field.

5) If a name attribute contains brackets, you must enclose it within quotes.

DEMO: http://jsfiddle.net/K6Wvk/

$(document).ready(function () {

    $('#formid').validate({ // initialize the plugin
        rules: {
            'test[]': {
                required: true,
                maxlength: 2
            }
        },
        messages: {
            'test[]': {
                required: "You must check at least 1 box",
                maxlength: "Check no more than {0} boxes"
            }
        }
    });

});

If you're only interested in international numbers and you'd like to be able to show the flag of the country that matches the country code in the input, I wrote a small library for that:

https://github.com/tfcporciuncula/phonemoji

Here's how it looks:

Probably not a direct answer to the question, but systemd can be used to run your application as a daemon. Here is an example:

[Unit]
Description=Python daemon
After=syslog.target
After=network.target

[Service]
Type=simple
User=<run as user>
Group=<run as group group>
ExecStart=/usr/bin/python <python script home>/script.py

# Give the script some time to startup
TimeoutSec=300

[Install]
WantedBy=multi-user.target

I prefer this method because a lot of the work is done for you, and then your daemon script behaves similarly to the rest of your system.

WebClient is a higher-level abstraction built on top of HttpWebRequest to simplify the most common tasks. For instance, if you want to get the content out of an HttpWebResponse, you have to read from the response stream:

var http = (HttpWebRequest)WebRequest.Create("http://example.com");
var response = http.GetResponse();

var stream = response.GetResponseStream();
var sr = new StreamReader(stream);
var content = sr.ReadToEnd();

With WebClient, you just do DownloadString:

var client = new WebClient();
var content = client.DownloadString("http://example.com");

Note: I left out the using statements from both examples for brevity. You should definitely take care to dispose your web request objects properly.

In general, WebClient is good for quick and dirty simple requests and HttpWebRequest is good for when you need more control over the entire request.

<script>$(function(){var svg = d3.select("#chart").append("svg:svg");});</script>
<div id="chart"></div>

In other words, it's not happening because you can't query against something that doesn't exist yet-- so just do it after the page loads (here via jquery).

Btw, its recommended that you place your JS files before the close of your body tag.

In ES6 you can use Math.sign function to determine if,

1. its +ve no
2. its -ve no
3. its zero (0)
4. its NaN


console.log(Math.sign(1))        // prints 1 
console.log(Math.sign(-1))       // prints -1
console.log(Math.sign(0))        // prints 0
console.log(Math.sign("abcd"))   // prints NaN

Just worked out for another solution as above example have bug( somewhere error ) for me. Variation from the selected answer.

html,body {

    min-height: -webkit-calc(100% - 30px);
    /* Opera */
    min-height: -o-calc(100% - 30px);
    /* Standard */
    min-height: calc(100% - 30px);
}

#footer {
    height:30px;
    margin: 0;
    clear: both;
    width:100%;
    position: relative;
}

for html layout

<body>
    <div id="nonFooter">header,middle,left,right,etc</div>
    <div id="footer"></div>
</body>

Well this way don't support old browser however its acceptable for old browser to scrolldown 30px to view the footer

For completing the answers, Spring MVC uses viewResolver(for example, as axtavt metionned, InternalResourceViewResolver) to get the specific view. Therefore the first step is making sure that a viewResolver is configured.

Secondly, you should pay attention to the url of redirection(redirect or forward). A url starting with "/" means that it's a url absolute in the application. As Jigar says,

return "redirect:/index.html";  

should work. If your view locates in the root of the application, Spring can find it. If a url without a "/", such as that in your question, it means a url relative. It explains why it worked before and don't work now. If your page calling "redirect" locates in the root by chance, it works. If not, Spring can't find the view and it doesn't work.

Here is the source code of the method of RedirectView of Spring

protected void renderMergedOutputModel(  
Map<String, Object> model, HttpServletRequest request, HttpServletResponse response)  
throws IOException {  
  // Prepare target URL.  
  StringBuilder targetUrl = new StringBuilder();  
  if (this.contextRelative && getUrl().startsWith("/")) {  
    // Do not apply context path to relative URLs.  
    targetUrl.append(request.getContextPath());  
  }  
  targetUrl.append(getUrl());  

  // ...  

  sendRedirect(request, response, targetUrl.toString(), this.http10Compatible);  
}  

In this case a loop will also do the job (and is usually sufficiently fast).

a <- array(0, dim=dim(X))
for (i in 1:ncol(X)) {a[,i] <- X[,i]}

document.getElementById("PdfContentArea").setAttribute('data', path);

OR

var objectEl = document.getElementById("PdfContentArea")

objectEl.outerHTML = objectEl.outerHTML.replace(/data="(.+?)"/, 'data="' + path + '"');

Variable that is not defined will cause compilation error.

What you're asking is about checking if it is initialized. But initialization is just a value, that you should choose and assign in the constructor.

For example:

class MyClass
{
    MyClass() : mCharacter('0'), mDecimal(-1.0){};
    void SomeMethod();

    char mCharacter;
    double mDecimal;
};

void MyClass::SomeMethod()
{
    if ( mCharacter != '0')
    {
        // touched after the constructor
        // do something with mCharacter.
    }

    if ( mDecimal != -1.0 )
    {
        // touched after the constructor
        // define mDecimal.
    }
}

You should initialize to a default value that will mean something in the context of your logic, of course.

Try this:

awk '{ $1=""; $2=""; $3=""; print $0 }'

I would do it using a for loop as shown below :

def determine_period(universe_array):
    tmp = universe_array
    for period in xrange(1, 13):
        tmp = apply_rules(tmp)
        if numpy.array_equal(tmp, universe_array):
            return period
    return 0

What about this:

double? amount = string.IsNullOrEmpty(strAmount) ? (double?)null : Convert.ToDouble(strAmount);

Of course, this doesn't take into account the convert failing.

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

In Certificates Panel, right click some certificate -> All tasks -> Manage private key -> Add IIS_IUSRS User with full control

In my case, I didnt't need to install my certificate with "Allow private key to be exported" option checked, like said in other answers.

I'd suggest you have a look at media-queries. This is a useful new addition to CSS that really makes so much sense, you'd wonder why this wasn't implemented waaay earlier. Basically it allows you to target browser attributes (such as max and min-widths) directly via CSS and branch your layout code from there. Similar to creating a print stylesheet, you can create your desktop and mobile layouts in parallel in the same file, which kicks ass for development.

have a look this way:

if (MessageBox.Show("Sure you wanna delete?", "Warning", MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.Yes)
{
  foreach (DataGridViewRow item in this.dataGridView1.SelectedRows)
  {
      bindingSource1.RemoveAt(item.Index);
  }
      adapter.Update(ds);
 }

<context:property-placeholder ... /> is the XML equivalent to the PropertyPlaceholderConfigurer. So, prefer that. The <util:properties/> simply factories a java.util.Properties instance that you can inject.

In Spring 3.1 (not 3.0...) you can do something like this:

@Configuration
@PropertySource("/foo/bar/services.properties")
public class ServiceConfiguration { 

    @Autowired Environment environment; 

    @Bean public javax.sql.DataSource dataSource( ){ 
        String user = this.environment.getProperty("ds.user");
        ...
    } 
}

In Spring 3.0, you can "access" properties defined using the PropertyPlaceHolderConfigurer mechanism using the SpEl annotations:

@Value("${ds.user}") private String user;

If you want to remove the XML all together, simply register the PropertyPlaceholderConfigurer manually using Java configuration. I prefer the 3.1 approach. But, if youre using the Spring 3.0 approach (since 3.1's not GA yet...), you can now define the above XML like this:

@Configuration 
public class MySpring3Configuration {     
        @Bean 
        public static PropertyPlaceholderConfigurer configurer() { 
             PropertyPlaceholderConfigurer ppc = ...
             ppc.setLocations(...);
             return ppc; 
        } 

        @Bean 
        public class DataSource dataSource(
                @Value("${ds.user}") String user, 
                @Value("${ds.pw}") String pw, 
                ...) { 
            DataSource ds = ...
            ds.setUser(user);
            ds.setPassword(pw);                        
            ...
            return ds;
        }
}

Note that the PPC is defined using a static bean definition method. This is required to make sure the bean is registered early, because the PPC is a BeanFactoryPostProcessor - it can influence the registration of the beans themselves in the context, so it necessarily has to be registered before everything else.

One option is to give the <a> a display of inline-block and then apply text-align: center; on the containing block (remove the float as well):

div { 
    background: red;
    overflow: hidden; 
    text-align: center;
}

span a {
    background: #222;
    color: #fff;
    display: inline-block;
    /* float:left;  remove */
    margin: 10px 10px 0 0;
    padding: 5px 10px
}

In C++20 you'll be able to do:

std::cout << std::format("{:03}", 25); // prints 025

In the meantime you can use the {fmt} library, std::format is based on.

Disclaimer: I'm the author of {fmt} and C++20 std::format.

The element.getBoundingClientRect() method will return the proper coordinates of an element relative to the viewport regardless of whether the svg has been scaled and/or translated.

See this question and answer.

While getBBox() works for an untransformed space, if scale and translation have been applied to the layout then it will no longer be accurate. The getBoundingClientRect() function has worked well for me in a force layout project when pan and zoom are in effect, where I wanted to attach HTML Div elements as labels to the nodes instead of using SVG Text elements.

Gentil Kiwi's answer is correct. He developed this mimikatz tool that is able to retrieve non-exportable private keys.

However, his instructions are outdated. You need:

1. Download the lastest release from https://github.com/gentilkiwi/mimikatz/releases

2. Run the cmd with admin rights in the same machine where the certificate was requested

3. Change to the mimikatz bin directory (Win32 or x64 version)

4. Run mimikatz

5. Follow the wiki instructions and the .pfx file (protected with password mimikatz) will be placed in the same folder of the mimikatz bin

} 

almost perfect Cartesian coordinates converted from barycentric are exported within *v (x) and *w (y) doubles. Both export doubles should have a * char before in every case, likely: *v and *w Code can be used for the other triangle of a quadrangle too. Hereby signed wrote only triangle abc from the clockwise abcd quad.

A---B

D---C 

the o point is inside ABC triangle for testing with with second triangle call this function CDA direction, and results should be correct after *v=1-*v; and *w=1-*w; for the quadrangle

Built on top of Wasim A.'s excellent idea to use serialization. The problem there was that the warning was also shown when the form was being submitted. This has been fixed here.

var isSubmitting = false

$(document).ready(function () {
    $('form').submit(function(){
        isSubmitting = true
    })

    $('form').data('initial-state', $('form').serialize());

    $(window).on('beforeunload', function() {
        if (!isSubmitting && $('form').serialize() != $('form').data('initial-state')){
            return 'You have unsaved changes which will not be saved.'
        }
    });
})

It has been tested in Chrome and IE 11.

For my this is best solution.

function strip_tags_content($string) { 
    // ----- remove HTML TAGs ----- 
    $string = preg_replace ('/<[^>]*>/', ' ', $string); 
    // ----- remove control characters ----- 
    $string = str_replace("\r", '', $string);
    $string = str_replace("\n", ' ', $string);
    $string = str_replace("\t", ' ', $string);
    // ----- remove multiple spaces ----- 
    $string = trim(preg_replace('/ {2,}/', ' ', $string));
    return $string; 

}

Using the release version of MVC, here is what I do:

[AcceptVerbs(HttpVerbs.Get)]
[OutputCache(CacheProfile = "CustomerImages")]
public FileResult Show(int customerId, string imageName)
{
    var path = string.Concat(ConfigData.ImagesDirectory, customerId, "\\", imageName);
    return new FileStreamResult(new FileStream(path, FileMode.Open), "image/jpeg");
}

I obviously have some application specific stuff in here regarding the path construction, but the returning of the FileStreamResult is nice and simple.

I did some performance testing in regards to this action against your everyday call to the image (bypassing the controller) and the difference between the averages was only about 3 milliseconds (controller avg was 68ms, non-controller was 65ms).

I had tried some of the other methods mentioned in answers here and the performance hit was much more dramatic... several of the solutions responses were as much as 6x the non-controller (other controllers avg 340ms, non-controller 65ms).

As Sagi stated in their answer DataTable.Load is a good solution. If you are trying to load multiple tables from a single reader you do not need to call DataReader.NextResult. The DataTable.Load method also advances the reader to the next result set (if any).

// Read every result set in the data reader.
while (!reader.IsClosed)
{
    DataTable dt = new DataTable();
    // DataTable.Load automatically advances the reader to the next result set
    dt.Load(reader);
    items.Add(dt);
}

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

This is an example of the use of this pattern that worked for me on empty datagrids.

<Style.Triggers>
    <DataTrigger Binding="{Binding Items.Count, RelativeSource={RelativeSource Self}}" Value="0">
        <Setter Property="Background">
            <Setter.Value>
                <VisualBrush Stretch="None">
                    <VisualBrush.Visual>
                        <TextBlock Text="We did't find any matching records for your search..." FontSize="16" FontWeight="SemiBold" Foreground="LightCoral"/>
                    </VisualBrush.Visual>
                </VisualBrush>
            </Setter.Value>
        </Setter>
    </DataTrigger>
</Style.Triggers>

You can do base64 encoding and decoding with simple javascript.

    $("input").keyup(function () {
     var value = $(this).val(),
         hash = Base64.encode(value);
     $(".test").html(hash);

     var decode = Base64.decode(hash);

     $(".decode").html(decode);
 });

var Base64={_keyStr:"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",encode:function(e){var t="";var n,r,i,s,o,u,a;var f=0;e=Base64._utf8_encode(e);while(f<e.length){n=e.charCodeAt(f++);r=e.charCodeAt(f++);i=e.charCodeAt(f++);s=n>>2;o=(n&3)<<4|r>>4;u=(r&15)<<2|i>>6;a=i&63;if(isNaN(r)){u=a=64}else if(isNaN(i)){a=64}t=t+this._keyStr.charAt(s)+this._keyStr.charAt(o)+this._keyStr.charAt(u)+this._keyStr.charAt(a)}return t},decode:function(e){var t="";var n,r,i;var s,o,u,a;var f=0;e=e.replace(/[^A-Za-z0-9+/=]/g,"");while(f<e.length){s=this._keyStr.indexOf(e.charAt(f++));o=this._keyStr.indexOf(e.charAt(f++));u=this._keyStr.indexOf(e.charAt(f++));a=this._keyStr.indexOf(e.charAt(f++));n=s<<2|o>>4;r=(o&15)<<4|u>>2;i=(u&3)<<6|a;t=t+String.fromCharCode(n);if(u!=64){t=t+String.fromCharCode(r)}if(a!=64){t=t+String.fromCharCode(i)}}t=Base64._utf8_decode(t);return t},_utf8_encode:function(e){e=e.replace(/rn/g,"n");var t="";for(var n=0;n<e.length;n++){var r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r)}else if(r>127&&r<2048){t+=String.fromCharCode(r>>6|192);t+=String.fromCharCode(r&63|128)}else{t+=String.fromCharCode(r>>12|224);t+=String.fromCharCode(r>>6&63|128);t+=String.fromCharCode(r&63|128)}}return t},_utf8_decode:function(e){var t="";var n=0;var r=c1=c2=0;while(n<e.length){r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r);n++}else if(r>191&&r<224){c2=e.charCodeAt(n+1);t+=String.fromCharCode((r&31)<<6|c2&63);n+=2}else{c2=e.charCodeAt(n+1);c3=e.charCodeAt(n+2);t+=String.fromCharCode((r&15)<<12|(c2&63)<<6|c3&63);n+=3}}return t}}

// Define the string
var string = 'Hello World!';

// Encode the String
var encodedString = Base64.encode(string);
console.log(encodedString); // Outputs: "SGVsbG8gV29ybGQh"

// Decode the String
var decodedString = Base64.decode(encodedString);
console.log(decodedString); // Outputs: "Hello World!"</script></div>

This is implemented in this Base64 encoder decoder

substr() would be best, you'll also want to check the length of the string first

$str = 'someLongString';
$max = 7;

if(strlen($str) > $max) {
   $str = substr($str, 0, $max) . '...';
}

wordwrap won't trim the string down, just split it up...

I recommend using the ValueProvider property of the controller, much in the way that UpdateModel/TryUpdateModel do to extract the route, query, and form parameters required. This will keep your method signatures from potentially growing very large and being subject to frequent change. It also makes it a little easier to test since you can supply a ValueProvider to the controller during unit tests.

For a fully transparent background use:

background: transparent;

Otherwise for a semi-transparent color fill use:

background: rgba(255,255,255,0.5); // or hsla(0, 0%, 100%, 0.5)

where the values are:

background: rgba(red,green,blue,opacity); // or hsla(hue, saturation, lightness, opacity)

You can also use rgba values for gradient backgrounds.

To get transparency on an image background simply reduce the opacity of the image in an image editor of you choice beforehand.

ORA-12154: TNS:could not resolve the connect identifier specified?

In case the TNS is not defined you can also try this one:

If you are using C#.net 2010 or other version of VS and oracle 10g express edition or lower version, and you make a connection string like this:

static string constr = @"Data Source=(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname )(PORT=1521)))
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));
    User Id=system ;Password=yourpasswrd"; 

After that you get error message ORA-12154: TNS:could not resolve the connect identifier specified then first you have to do restart your system and run your project.

And if Your windows is 64 bit then you need to install oracle 11g 32 bit and if you installed 11g 64 bit then you need to Install Oracle 11g Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio version 11.2.0.1.2 or later from OTN and check it in Oracle Universal Installer Please be sure that the following are checked:

Oracle Data Provider for .NET 2.0

Oracle Providers for ASP.NET

Oracle Developer Tools for Visual Studio

Oracle Instant Client 

And then restart your Visual Studio and then run your project .... NOTE:- SYSTEM RESTART IS necessary TO SOLVE THIS TYPES OF ERROR.......

If you have your folder as an object, let's say that you created it in the same script using next command:

$folder = New-Item -ItemType Directory -Force -Path "c:\tmp" -Name "myFolder"

Then you can just remove it like this in the same script

$folder.Delete($true)

$true - states for recursive removal

<div

 onmousedown="return false;">

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

Expanding on @Ryan G mentioned usage of the pandas.DataFrame.astype(<type>) method, one can use the errors=ignore argument to only convert those columns that do not produce an error, which notably simplifies the syntax. Obviously, caution should be applied when ignoring errors, but for this task it comes very handy.

>>> df = pd.DataFrame(np.random.rand(3, 4), columns=list('ABCD'))
>>> df *= 10
>>> print(df)
...           A       B       C       D
... 0   2.16861 8.34139 1.83434 6.91706
... 1   5.85938 9.71712 5.53371 4.26542
... 2   0.50112 4.06725 1.99795 4.75698

>>> df['E'] = list('XYZ')
>>> df.astype(int, errors='ignore')
>>> print(df)
...     A   B   C   D   E
... 0   2   8   1   6   X
... 1   5   9   5   4   Y
... 2   0   4   1   4   Z

From pandas.DataFrame.astype docs:

errors : {‘raise’, ‘ignore’}, default ‘raise’

Control raising of exceptions on invalid data for provided dtype.

• raise : allow exceptions to be raised
• ignore : suppress exceptions. On error return original object

Here is another method to get date

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

This problem is because of the fact that eclipse is not able to find Java ,

Check the java directory cd /Library/Java/JavaVirtualMachines///Contents/Home/jre/bin

If thats not present down JDK from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Once JDK is installed change eclipse.ini file

On Mac: Right click on Eclipse icon and click "Show package Content"

Navigate to eclipse>Contents>Eclipse>eclipse.ini

Open the file and replace the java path after "-vm" with this

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/bin

I think this will do:

I have been struggling with the problem for a few days now.

The problem for me originated with VirtualBox/Ubuntu. I have lots of USB serial ports on my machine. When I tried to assign one of them to the VM it clobbered all of them - i.e. the host and other VMs were no longer able to use their USB serial devices.

My solution is to set up a stand-alone serial server on a netbook I happen to have in the closet.

I tried ser2net and it worked to put the serial port on the wire, but remtty did not work. I need to get the port as a tty on the VM.

socat worked perfectly.

There are good instructions here:

The below jsfiddle link will help you understand how to rotate a image.I used the same one to rotate the dial of a clock.

http://jsfiddle.net/xw89p/

var rotation = function (){
   $("#image").rotate({
      angle:0, 
      animateTo:360, 
      callback: rotation,
      easing: function (x,t,b,c,d){       
          return c*(t/d)+b;
      }
   });
}
rotation();

Where: • t: current time,

• b: begInnIng value,

• c: change In value,

• d: duration,

• x: unused

No easing (linear easing): function(x, t, b, c, d) { return b+(t/d)*c ; }

It seems that it doesn't turn it into a string. Try

row.HeaderCell.Value = String.Format("{0}", row.Index + 1);

This is to help fill in the gaps in Adrien Plisson's answer (which should be upvoted as soon as he edits it ;-):

you can also get the fully qualified path of your first argument by using %~f1, but this gives a path according to the current path, which is obviously not what you want.

unfortunately, i don't know how to mix the 2 together...

One can handle %0 and %1 likewise:

• %~dpnx0 for fully qualified drive+path+name+extension of the batchfile itself,
  %~f0 also suffices;
• %~dpnx1 for fully qualified drive+path+name+extension of its first argument [if that's a filename at all],
  %~f1 also suffices;

%~f1 will work independent of how you did specify your first argument: with relative paths or with absolute paths (if you don't specify the file's extension when naming %1, it will not be added, even if you use %~dpnx1 -- however.

But how on earth would you name a file on a different drive anyway if you wouldn't give that full path info on the commandline in the first place?

However, %~p0, %~n0, %~nx0 and %~x0 may come in handy, should you be interested in path (without driveletter), filename (without extension), full filename with extension or filename's extension only. But note, while %~p1 and %~n1 will work to find out the path or name of the first argument, %~nx1 and %~x1 will not add+show the extension, unless you used it on the commandline already.

While ("run as SYSTEM") works, people should be advised this means going from a minimum-permissions type account to an account which has all permissions in the world. Which is very much not a recommended setup best practices or security-wise.

If you know what you are doing and know your SQL Server will always be run in an isolated environment (i.e. not on hotel or airport wifi) it's probably fine, but this creates a very real attack vector which can completely compromise a machine if on open internets.

This seems to be an error on Microsoft's part and people should be aware of the implications of the workaround posted.

I haven't had a problem just using Unix-style path separators, even on Windows (though it is good practice to check File.separatorChar).

The technique of using ClassLoader.getResource() is best for read-only resources that are going to be loaded from JAR files. Sometimes, you can programmatically determine the application directory, which is useful for admin-configurable files or server applications. (Of course, user-editable files should be stored somewhere in the System.getProperty("user.home") directory.)

You should Build your app instead of debugging process. Just follow this:

Build -> Build Bundles/APK(s) -> Build APK(s)

You have to use a more complex function like $.ajax() if you want to control caching on a per-request basis. Or, if you just want to turn it off for everything, put this at the top of your script:

$.ajaxSetup ({
    // Disable caching of AJAX responses
    cache: false
});

A bin file is just the bits and bytes that go into the rom or a particular address from which you will run the program. You can take this data and load it directly as is, you need to know what the base address is though as that is normally not in there.

An elf file contains the bin information but it is surrounded by lots of other information, possible debug info, symbols, can distinguish code from data within the binary. Allows for more than one chunk of binary data (when you dump one of these to a bin you get one big bin file with fill data to pad it to the next block). Tells you how much binary you have and how much bss data is there that wants to be initialised to zeros (gnu tools have problems creating bin files correctly).

The elf file format is a standard, arm publishes its enhancements/variations on the standard. I recommend everyone writes an elf parsing program to understand what is in there, dont bother with a library, it is quite simple to just use the information and structures in the spec. Helps to overcome gnu problems in general creating .bin files as well as debugging linker scripts and other things that can help to mess up your bin or elf output.

I found myself needing the same thing for a recent project. Building on Levi's solution, here's a cleaner and faster method:

Rack::Utils.parse_nested_query 'param1=value1&param2=value2&param3=value3'
# => {"param1"=>"value1", "param2"=>"value2", "param3"=>"value3"}

What is the package name of your class? If there is no package name, then most likely the solution is:

java -cp FileManagement Main

Also take a look at awesome project aqtinstall https://github.com/miurahr/aqtinstall/ (it can install any Qt version on Linux, Mac and Windows machines without any interaction!) and GitHub Action that uses this tool: https://github.com/jurplel/install-qt-action

If we have to answer the question: String is a reference type and it behaves as a reference. We pass a parameter that holds a reference to, not the actual string. The problem is in the function:

public static void TestI(string test)
{
    test = "after passing";
}

The parameter test holds a reference to the string but it is a copy. We have two variables pointing to the string. And because any operations with strings actually create a new object, we make our local copy to point to the new string. But the original test variable is not changed.

The suggested solutions to put ref in the function declaration and in the invocation work because we will not pass the value of the test variable but will pass just a reference to it. Thus any changes inside the function will reflect the original variable.

I want to repeat at the end: String is a reference type but since its immutable the line test = "after passing"; actually creates a new object and our copy of the variable test is changed to point to the new string.

Starting file:

     line 1
   line 2
line 3  
      line 4 

Code:

with open("filename.txt", "r") as f:
    lines = f.readlines()
    for line in lines:
        stripped = line.strip()
        print(stripped)

Output:

line 1
line 2
line 3
line 4

First record:

SELECT <some columns> FROM mytable
<maybe some joins here>
WHERE <various conditions>
ORDER BY date ASC
LIMIT 1

Last record:

SELECT <some columns> FROM mytable
<maybe some joins here>
WHERE <various conditions>
ORDER BY date DESC
LIMIT 1

The key to debugging situations like these is to run the subquery/inline view on its' own to see what the output is:

  SELECT TOP 1 
         dm.marker_value, 
         dum.profile_id
    FROM DPS_USR_MARKERS dum (NOLOCK)
    JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                AND dm.marker_key = 'moneyBackGuaranteeLength'
ORDER BY dm.creation_date

Running that, you would see that the profile_id value didn't match the u.id value of u162231993, which would explain why any mbg references would return null (thanks to the left join; you wouldn't get anything if it were an inner join).

You've coded yourself into a corner using TOP, because now you have to tweak the query if you want to run it for other users. A better approach would be:

   SELECT u.id, 
          x.marker_value 
     FROM DPS_USER u
LEFT JOIN (SELECT dum.profile_id,
                  dm.marker_value,
                  dm.creation_date
             FROM DPS_USR_MARKERS dum (NOLOCK)
             JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                         AND dm.marker_key = 'moneyBackGuaranteeLength'
           ) x ON x.profile_id = u.id
     JOIN (SELECT dum.profile_id,
                  MAX(dm.creation_date) 'max_create_date'
             FROM DPS_USR_MARKERS dum (NOLOCK)
             JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                         AND dm.marker_key = 'moneyBackGuaranteeLength'
         GROUP BY dum.profile_id) y ON y.profile_id = x.profile_id
                                   AND y.max_create_date = x.creation_date
    WHERE u.id = 'u162231993'

With that, you can change the id value in the where clause to check records for any user in the system.

I have to set the selection style to UITableViewCellSelectionStyleDefault for custom background color to work. If any other style, the custom background color will be ignored. Tested on iOS 8.

The full code for the cell as follows:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"MyCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    // This is how you change the background color
    cell.selectionStyle = UITableViewCellSelectionStyleDefault;
    UIView *bgColorView = [[UIView alloc] init];
    bgColorView.backgroundColor = [UIColor redColor];
    [cell setSelectedBackgroundView:bgColorView];

    return cell;
}

A .java file is the code file. A .class file is the compiled file.

It's not exactly "conversion" - it's compilation. Suppose your file was called "herb.java", you would write (in the command prompt):

 javac herb.java

It will create a herb.class file in the current folder.

It is "executable" only if it contains a static void main(String[]) method inside it. If it does, you can execute it by running (again, command prompt:)

 java herb

A little helper function I use with some header checking safeguards to handle it all:

def appendDFToCSV_void(df, csvFilePath, sep=","):
    import os
    if not os.path.isfile(csvFilePath):
        df.to_csv(csvFilePath, mode='a', index=False, sep=sep)
    elif len(df.columns) != len(pd.read_csv(csvFilePath, nrows=1, sep=sep).columns):
        raise Exception("Columns do not match!! Dataframe has " + str(len(df.columns)) + " columns. CSV file has " + str(len(pd.read_csv(csvFilePath, nrows=1, sep=sep).columns)) + " columns.")
    elif not (df.columns == pd.read_csv(csvFilePath, nrows=1, sep=sep).columns).all():
        raise Exception("Columns and column order of dataframe and csv file do not match!!")
    else:
        df.to_csv(csvFilePath, mode='a', index=False, sep=sep, header=False)

I found other answers were either not generic enough, or too complicated. Here is a simple one that should always work (for bootstrap 3):

$('[data-toggle="popover"]').each(function () {
    var button = $(this);
    button.popover().on('shown.bs.popover', function() {
        button.data('bs.popover').tip().find('[data-dismiss="popover"]').on('click', function () {
            button.popover('toggle');
        });
    });
});

Then just add attribute data-dismiss="popover" in your close button. Also make sure not to use popover('hide') elsewhere in your code as it hides the popup but doesn't properly sets its internal state in bootstrap code, which will cause issues next time you use popover('toggle').

Advanced way to check the exact word, that we need to find in a long string:

import re
text = "This text was of edited by Rock"
#try this string also
#text = "This text was officially edited by Rock" 
for m in re.finditer(r"\bof\b", text):
    if m.group(0):
        print "Present"
    else:
        print "Absent"

Expanding on mhawke's answer this is what I've implemented. It removes all the content of a folder but not the folder itself. Tested on Linux with files, folders and symbolic links, should work on Windows as well.

import os
import shutil

for root, dirs, files in os.walk('/path/to/folder'):
    for f in files:
        os.unlink(os.path.join(root, f))
    for d in dirs:
        shutil.rmtree(os.path.join(root, d))

If you remove the href attribute the anchor will be not focusable and it will look like simple text, but it will still be clickable.

I would suggest anyone to write down the full command

git log --all --decorate --oneline --graph

rather than create an alias.

It's good to get the commands into your head, so you know it by heart i.e. do not depend on aliases when you change machines.

1) Others (especially dirkgently) have noted that buffer needs to be allocated some memory space. For smallish values of N (say, N <= 4096), you can also allocate it on the stack:

#define BUFFER_SIZE 4096
char buffer[BUFFER_SIZE]

This saves you the worry of ensuring that you delete[] the buffer should an exception be thrown.

But remember that stacks are finite in size (so are heaps, but stacks are finiter), so you don't want to put too much there.

2) On a -1 return code, you should not simply return immediately (throwing an exception immediately is even more sketchy.) There are certain normal conditions that you need to handle, if your code is to be anything more than a short homework assignment. For example, EAGAIN may be returned in errno if no data is currently available on a non-blocking socket. Have a look at the man page for read(2).

You could use Timestamp.valueOf(String). The documentation states that it understands timestamps in the format yyyy-mm-dd hh:mm:ss[.f...], so you might need to change the field separators in your incoming string.

Then again, if you're going to do that then you could just parse it yourself and use the setNanos method to store the microseconds.

If you are trying to track down which line caused an error, if you right-click in the Python shell where the line error is displayed it will come up with a "Go to file/line" which takes you directly to the line in question.

You're better off using typed np.arrays, and then pass the data and column names as a dictionary.

import numpy as np
import pandas as pd
# Feature: np arrays are 1: efficient, 2: can be pre-sized
x = np.array(['a', 'b'], dtype=object)
y = np.array([ 1 ,  2 ], dtype=np.int32)
df = pd.DataFrame({
   'x' : x,    # Feature: column name is near data array
   'y' : y,
   }
 )

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

Output:

abcd

You can do these conversions also with the .NET Framework:

JSON to XML: by using System.Runtime.Serialization.Json

var xml = XDocument.Load(JsonReaderWriterFactory.CreateJsonReader(
    Encoding.ASCII.GetBytes(jsonString), new XmlDictionaryReaderQuotas()));

XML to JSON: by using System.Web.Script.Serialization

var json = new JavaScriptSerializer().Serialize(GetXmlData(XElement.Parse(xmlString)));

private static Dictionary<string, object> GetXmlData(XElement xml)
{
    var attr = xml.Attributes().ToDictionary(d => d.Name.LocalName, d => (object)d.Value);
    if (xml.HasElements) attr.Add("_value", xml.Elements().Select(e => GetXmlData(e)));
    else if (!xml.IsEmpty) attr.Add("_value", xml.Value);

    return new Dictionary<string, object> { { xml.Name.LocalName, attr } };
}

With Ubuntu 14.4 I had to change the file /etc/default/jenkins

E.g.

   #HTTP_PORT=8080
   HTTP_PORT=8083

and restart the service

service jenkins restart

simple:

Tags are expected to always point at the same version of a project, while heads are expected to advance as development progresses.

Git User Manual

Piping some greps can do it (it runs in POSIX shell and under BusyBox):

cat my-file | grep -A1 my-regexp | grep -v -- '--' | grep -v my-regexp

1. -v will show non-matching lines
2. -- is printed by grep to separate each match, so we skip that too

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

You can do this in a couple of ways.

One, is to build up the query yourself and execute it.

SET @sql = 'SELECT ' + @columnName + ' FROM yourTable'
sp_executesql @sql

If you opt for that method, be very certain to santise your input. Even if you know your application will only give 'real' column names, what if some-one finds a crack in your security and is able to execute the SP directly? Then they can execute just about anything they like. With dynamic SQL, always, always, validate the parameters.

Alternatively, you can write a CASE statement...

SELECT
  CASE @columnName
    WHEN 'Col1' THEN Col1
    WHEN 'Col2' THEN Col2
                ELSE NULL
  END as selectedColumn
FROM
  yourTable

This is a bit more long winded, but a whole lot more secure.

1. You should add L: long i = 12345678910L;.
2. Yes.

BTW: it doesn't have to be an upper case L, but lower case is confused with 1 many times :).

Perhaps of interest, the Google Finance API documentaton includes a section detailing how to access different parameters via JavaScript.

I suppose the JavaScript API might be a wrapper to the JSON request you mention above... perhaps you could check which HTTP requests are being sent.

Actually, there are two foreign_key_checks variables: a global variable and a local (per session) variable. Upon connection, the session variable is initialized to the value of the global variable.
The command SET foreign_key_checks modifies the session variable.
To modify the global variable, use SET GLOBAL foreign_key_checks or SET @@global.foreign_key_checks.

Consult the following manual sections:
http://dev.mysql.com/doc/refman/5.7/en/using-system-variables.html
http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html

Finally, the latest node.js release v10.3.0 has natively supported fs promises.

const fsPromises = require('fs').promises; // or require('fs/promises') in v10.0.0
fsPromises.writeFile(ASIN + '.json', JSON.stringify(results))
  .then(() => {
    console.log('JSON saved');
  })
  .catch(er => {
    console.log(er);
  });

You can check the official documentation for more details. https://nodejs.org/api/fs.html#fs_fs_promises_api

The reference is the unique identifier for the object. I don't know of any way of converting this into anything like a string etc. The value of the reference will change during compaction (as you've seen), but every previous value A will be changed to value B, so as far as safe code is concerned it's still a unique ID.

If the objects involved are under your control, you could create a mapping using weak references (to avoid preventing garbage collection) from a reference to an ID of your choosing (GUID, integer, whatever). That would add a certain amount of overhead and complexity, however.

You try to instantiate an object of the Friends class like this:

Friends f = new Friends(friendsName, friendsAge);

The class does not have a constructor that takes parameters. You should either add the constructor, or create the object using the constructor that does exist and then use the set-methods. For example, instead of the above:

Friends f = new Friends();
f.setName(friendsName);
f.setAge(friendsAge);

Perhaps you need to read about interactive usage of Matplotlib. However, if you are going to build an app, you should be using the API and embedding the figures in the windows of your chosen GUI toolkit (see examples/embedding_in_tk.py, etc).

In Github You need to write:

<p align="justify">
  Lorem ipsum
</p>

onclick="window.open(this.href,'_blank');return false;"

As pointed out in this comment How do you check in python whether a string contains only numbers? the isdigit() method is not totally accurate for this use case, because it returns True for some digit-like characters:

>>> "\u2070".isdigit() # unicode escaped 'superscript zero' 
True

If this needs to be avoided, the following simple function checks, if all characters in a string are a digit between "0" and "9":

import string

def contains_only_digits(s):
    # True for "", "0", "123"
    # False for "1.2", "1,2", "-1", "a", "a1"
    for ch in s:
        if not ch in string.digits:
            return False
    return True

Used in the example from the question:

if len(isbn) == 10 and contains_only_digits(isbn):
    print ("Works")

You can use this implementation that ExecutorService provides

invokeAll(Collection<? extends Callable<T>> tasks,long timeout, TimeUnit unit)
as

executor.invokeAll(Arrays.asList(task), 2 , TimeUnit.SECONDS);

However, in my case, I could not as Arrays.asList took extra 20ms.

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

Lots of answers found here for creating multidimensional arrays in bash.

And without exception, all are obtuse and difficult to use.

If MD arrays are a required criteria, it is time to make a decision:

Use a language that supports MD arrays

My preference is Perl. Most would probably choose Python. Either works.

Store the data elsewhere

JSON and jq have already been suggested. XML has also been suggested, though for your use JSON and jq would likely be simpler.

It would seem though that Bash may not be the best choice for what you need to do.

Sometimes the correct question is not "How do I do X in tool Y?", but rather "Which tool would be best to do X?"

You can put this configuration in your settings.xml file:

I recently was trying to do something similar. I decided I didn't like the sliding animation of the UINavigationController, but I also didn't want to do the animations that UIView gives you like curl or anything like that. I wanted to do a cross fade between the views when I push or pop.

The problem there involves the fact that the view is literally removing the view or popping one over the top of the current one, so a fade doesn't work. The solution I came to involved taking my new view and adding it as a subview to the current top view on the UIViewController's stack. I add it with an alpha of 0, then do a crossfade. When the animation sequence finishes, I push the view onto the stack without animating it. I then go back to the old topView and clean up stuff that I had changed.

Its a little more complicated than that, because you have the navigationItems you have to adjust to make the transition look correct. Also, if you do any rotation, you then have to adjust frame sizes as you add the views as subviews so they show up correctly on screen. Here is some of the code I used. I subclassed the UINavigationController and overrode the push and the pop methods.

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
      UIViewController *currentViewController = [self.viewControllers lastObject];
      //if we don't have a current controller, we just do a normal push
      if(currentViewController == nil)
      {
         [super pushViewController:viewController animated:animated];
         return;
      }
      //if no animation was requested, we can skip the cross fade
      if(!animation)
      {
         [super pushViewController:viewController animated:NO];
         return;
      }
      //start the cross fade.  This is a tricky thing.  We basically add the new view
//as a subview of the current view, and do a cross fade through alpha values.
//then we push the new view on the stack without animating it, so it seemlessly is there.
//Finally we remove the new view that was added as a subview to the current view.

viewController.view.alpha = 0.0;
//we need to hold onto this value, we'll be releasing it later
    NSString *title = [currentViewController.title retain];

//add the view as a subview of the current view
[currentViewController.view addSubview:viewController.view];
[currentViewController.view bringSubviewToFront:viewController.view];
UIBarButtonItem *rButtonItem = currentViewController.navigationItem.rightBarButtonItem;
UIBarButtonItem *lButtonItem = currentViewController.navigationItem.leftBarButtonItem;

NSArray *array = nil;

//if we have a right bar button, we need to add it to the array, if not, we will crash when we try and assign it
//so leave it out of the array we are creating to pass as the context.  I always have a left bar button, so I'm not checking to see if it is nil. Its a little sloppy, but you may want to be checking for the left BarButtonItem as well.
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,nil];
}

//remove the right bar button for our transition
[currentViewController.navigationItem setRightBarButtonItem:nil animated:YES];
//remove the left bar button and create a backbarbutton looking item
//[currentViewController.navigationItem setLeftBarButtonItem:nil animated:NO];

//set the back button
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:title style:kButtonStyle target:self action:@selector(goBack)];
[currentViewController.navigationItem setLeftBarButtonItem:backButton animated:YES];
[viewController.navigationItem setLeftBarButtonItem:backButton animated:NO];
[backButton release];

[currentViewController setTitle:viewController.title];

[UIView beginAnimations:@"push view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePushDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[viewController.view setAlpha: 1.0];
[UIView commitAnimations];
}

-(void)animationForCrossFadePushDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{

UIViewController *c = [(NSArray*)context objectAtIndex:0];
UIViewController *n = [(NSArray*)context objectAtIndex:1];
NSString *title     = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:3];
UIBarButtonItem *r = nil;
//not all views have a right bar button, if we look for it and it isn't in the context,
//we'll crash out and not complete the method, but the program won't crash.
//So, we need to check if it is there and skip it if it isn't.
if([(NSArray *)context count] == 5)
    r = [(NSArray *)context objectAtIndex:4];

//Take the new view away from being a subview of the current view so when we go back to it
//it won't be there anymore.
[[[c.view subviews] lastObject] removeFromSuperview];
[c setTitle:title];
[title release];
//set the search button
[c.navigationItem setLeftBarButtonItem:l animated:NO];
//set the next button
if(r != nil)
    [c.navigationItem setRightBarButtonItem:r animated:NO];


[super pushViewController:n animated:NO];

 }

As I mention in the code, I always have a left bar button item, so I don't check to see if it is nil before putting it in the array that I pass as the context for the animation delegate. If you do this, you may want to make that check.

The problem I found was that if you crash at all in the delegate method, it won't crash the program. It just stops the delegate from completing but you don't get any kind of warning.
So since I was doing my cleanup in that delegate routine, it was causing some weird visual behavior since it wasn't finishing the cleanup.

The back button I create calls a "goBack" method, and that method just calls the pop routine.

-(void)goBack
{ 
     [self popViewControllerAnimated:YES];
}

Also, here is my pop routine.

-(UIViewController *)popViewControllerAnimated:(BOOL)animated
{
    //get the count for the number of viewControllers on the stack
int viewCount = [[self viewControllers] count];
//get the top view controller on the stack
UIViewController *topViewController = [self.viewControllers objectAtIndex:viewCount - 1];
//get the next viewController after the top one (this will be the new top one)
UIViewController *newTopViewController = [self.viewControllers objectAtIndex:viewCount - 2];

//if no animation was requested, we can skip the cross fade
if(!animated)
{
    [super popViewControllerAnimated:NO];
            return topViewController;
}



//start of the cross fade pop.  A bit tricky.  We need to add the new top controller
//as a subview of the curent view controler with an alpha of 0.  We then do a cross fade.
//After that we pop the view controller off the stack without animating it.
//Then the cleanup happens: if the view that was popped is not released, then we
//need to remove the subview we added and change some titles back.
newTopViewController.view.alpha = 0.0;
[topViewController.view addSubview:newTopViewController.view];
[topViewController.view bringSubviewToFront:newTopViewController.view];
NSString *title = [topViewController.title retain];
UIBarButtonItem *lButtonItem = topViewController.navigationItem.leftBarButtonItem;
UIBarButtonItem *rButtonItem = topViewController.navigationItem.rightBarButtonItem;

//set the new buttons on top of the current controller from the new top controller
if(newTopViewController.navigationItem.leftBarButtonItem != nil)
{
    [topViewController.navigationItem setLeftBarButtonItem:newTopViewController.navigationItem.leftBarButtonItem animated:YES];
}
if(newTopViewController.navigationItem.rightBarButtonItem != nil)
{
    [topViewController.navigationItem setRightBarButtonItem:newTopViewController.navigationItem.rightBarButtonItem animated:YES];
}

[topViewController setTitle:newTopViewController.title];
//[topViewController.navigationItem.leftBarButtonItem setTitle:newTopViewController.navigationItem.leftBarButtonItem.title];

NSArray *array = nil;
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:topViewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:topViewController,title,lButtonItem,nil];
}


[UIView beginAnimations:@"pop view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePopDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[newTopViewController.view setAlpha: 1.0];
[UIView commitAnimations];
return topViewController;

 }

 -(void)animationForCrossFadePopDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
 {

UIViewController *c = [(NSArray *)context objectAtIndex:0];
//UIViewController *n = [(NSArray *)context objectAtIndex:1];
NSString *title = [(NSArray *)context objectAtIndex:1];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *r = nil;



//Not all views have a right bar button.  If we look for one that isn't there
// we'll crash out and not complete this method, but the program will continue.
//So we need to check if it is therea nd skip it if it isn't.
if([(NSArray *)context count] == 4)
    r = [(NSArray *)context objectAtIndex:3];

//pop the current view from the stack without animation
[super popViewControllerAnimated:NO];

//if what was the current veiw controller is not nil, then lets correct the changes
//we made to it.
if(c != nil)
{
    //remove the subview we added for the transition
    [[c.view.subviews lastObject] removeFromSuperview];
    //reset the title we changed
    c.title = title;
    [title release];
    //replace the left bar button that we changed
    [c.navigationItem setLeftBarButtonItem:l animated:NO];
    //if we were passed a right bar button item, replace that one as well
    if(r != nil)
        [c.navigationItem setRightBarButtonItem:r animated:NO];
    else {
        [c.navigationItem setRightBarButtonItem:nil animated:NO];
    }


 }
}

That's pretty much it. You'll need some additional code if you want to implement rotations. You'll need to set the frame size of your views that you add as subviews before you show them otherwise you'll run into issues the orientation is landscape, but the last time you saw the previous view it was portrait. So, then you add it as a sub view and fade it in but it shows up as portrait, then when we pop without animation, the same view, but the one that is in the stack, now is landscape. The whole thing looks a little funky. Everyone's implementation of rotation is a little different so I didn't include my code for that here.

Hope it helps some people. I've looked all over for something like this and couldn't find anything. I don't think this is the perfect answer, but it is working real well for me at this point.

Try the Jquery Hotkeys plugin instead - it'll do everything you require.

jQuery Hotkeys is a plug-in that lets you easily add and remove handlers for keyboard events anywhere in your code supporting almost any key combination.

This plugin is based off of the plugin by Tzury Bar Yochay: jQuery.hotkeys

The syntax is as follows:

$(expression).bind(types, keys, handler); $(expression).unbind(types, handler);

$(document).bind('keydown', 'ctrl+a', fn);

// e.g. replace '$' sign with 'EUR'
// $('input.foo').bind('keyup', '$', function(){   
//      this.value = this.value.replace('$', 'EUR'); });

this:

$('#rblDiv input').click(function(){
    alert($('#rblDiv input').index(this));
});

will get you the index of the radio button that was clicked (i think, untested) (note you've had to wrap your RBL in #rblDiv

you could then use that to display the corresponding div like this:

$('.divCollection div:eq(' + $('#rblDiv input').index(this) +')').show();

Is that what you meant?

Edit: Another approach would be to give the rbl a class name, then go:

$('.rblClass').val();

Good answers though, anyway I want to share my Object Oriented solution Up to date for swift 5.

please check it out: AsyncTask

Conceptually inspired by android's AsyncTask, I've wrote my own class in Swift

AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread.

Here are few usage examples

Example 1 -

AsyncTask(backgroundTask: {(p:String)->Void in//set BGParam to String and BGResult to Void
        print(p);//print the value in background thread
    }).execute("Hello async");//execute with value 'Hello async'

Example 2 -

let task2=AsyncTask(beforeTask: {
           print("pre execution");//print 'pre execution' before backgroundTask
        },backgroundTask:{(p:Int)->String in//set BGParam to Int & BGResult to String
            if p>0{//check if execution value is bigger than zero
               return "positive"//pass String "poitive" to afterTask
            }
            return "negative";//otherwise pass String "negative"
        }, afterTask: {(p:String) in
            print(p);//print background task result
    });
    task2.execute(1);//execute with value 1

It has 2 generic types:

• BGParam - the type of the parameter sent to the task upon execution.

• BGResult - the type of the result of the background computation.

  When you create an AsyncTask you can those types to whatever you need to pass in and out of the background task, but if you don't need those types, you can mark it as unused with just setting it to: Void or with shorter syntax: ()

When an asynchronous task is executed, it goes through 3 steps:

1. beforeTask:()->Void invoked on the UI thread just before the task is executed.
2. backgroundTask: (param:BGParam)->BGResult invoked on the background thread immediately after
3. afterTask:(param:BGResult)->Void invoked on the UI thread with result from the background task

Use 4 spaces.

Here's a screenshot from that updated repo:

Thanks @Waylan, your comment was exactly right.

As of MongoDB 2.4, you can use $setOnInsert (http://docs.mongodb.org/manual/reference/operator/setOnInsert/)

Set 'insertion_date' using $setOnInsert and 'last_update_date' using $set in your upsert command.

To turn your pseudocode into a working example:

now = datetime.utcnow()
for document in update:
    collection.update_one(
        {"_id": document["_id"]},
        {
            "$setOnInsert": {"insertion_date": now},
            "$set": {"last_update_date": now},
        },
        upsert=True,
    )

$('#myDiv').hide();

or

$('#myDiv').slideUp();

or

$('#myDiv').fadeOut();

You could also use

$(this).find('img');

which would return all imgs that are descendants of the div

While it's not currently possible with the script tag, it is possible with an iframe if it's from the same domain.

<iframe
id="mySpecialId"
src="/my/link/to/some.json"
onload="(()=>{if(!window.jsonData){window.jsonData={}}try{window.jsonData[this.id]=JSON.parse(this.contentWindow.document.body.textContent.trim())}catch(e){console.warn(e)}this.remove();})();"
onerror="((err)=>console.warn(err))();"
style="display: none;"
></iframe>

To use the above, simply replace the id and src attribute with what you need. The id (which we'll assume in this situation is equal to mySpecialId) will be used to store the data in window.jsonData["mySpecialId"].

In other words, for every iframe that has an id and uses the onload script will have that data synchronously loaded into the window.jsonData object under the id specified.

I did this for fun and to show that it's "possible' but I do not recommend that it be used.

Here is an alternative that uses a callback instead.

<script>
    function someCallback(data){
        /** do something with data */
        console.log(data);

    }
    function jsonOnLoad(callback){
        const raw = this.contentWindow.document.body.textContent.trim();
        try {
          const data = JSON.parse(raw);
          /** do something with data */
          callback(data);
        }catch(e){
          console.warn(e.message);
        }
        this.remove();
    }
</script>
<!-- I frame with src pointing to json file on server, onload we apply "this" to have the iframe context, display none as we don't want to show the iframe -->
<iframe src="your/link/to/some.json" onload="jsonOnLoad.apply(this, someCallback)" style="display: none;"></iframe>

Tested in chrome and should work in firefox. Unsure about IE or Safari.

I prefer using linq-to-json feature of JSON.NET framework. Here's how you can serialize a list of your objects to json.

List<MyObject> list = new List<MyObject>();

Func<MyObject, JObject> objToJson =
    o => new JObject(
            new JProperty("ObjectId", o.ObjectId), 
            new JProperty("ObjectString", o.ObjectString));

string result = new JObject(new JArray(list.Select(objToJson))).ToString();

You fully control what will be in the result json string and you clearly see it just looking at the code. Surely, you can get rid of Func<T1, T2> declaration and specify this code directly in the new JArray() invocation but with this code extracted to Func<> it looks much more clearer what is going on and how you actually transform your object to json. You can even store your Func<> outside this method in some sort of setup method (i.e. in constructor).

This should work:

private string rel(string path) {
  string[] cwd  = new Regex(@"[\\]").Split(Directory.GetCurrentDirectory());
  string[] fp   = new Regex(@"[\\]").Split(path);

  int common = 0;

  for (int n = 0; n < fp.Length; n++) {
    if (n < cwd.Length && n < fp.Length && cwd[n] == fp[n]) {
      common++;
    }
  }

  if (common > 0) {
    List<string> rp = new List<string>();

    for (int n = 0; n < (cwd.Length - common); n++) {
      rp.Add("..");
    }

    for (int n = common; n < fp.Length; n++) {
      rp.Add(fp[n]);
    }

    return String.Join("/", rp.ToArray());
  } else {
    return String.Join("/", fp);
  }
}

Every time I go from heavy C++ coding to Java, it takes me a little while to adapt to the lack of const-correctness in Java. This usage of const in C++ is much different than just declaring constant variables, if you didn't know. Essentially, it ensures that an object is immutable when accessed through a special kind of pointer called a const-pointer When in Java, in places where I'd normally want to return a const-pointer, I instead return a reference with an interface type containing only methods that shouldn't have side effects. Unfortunately, this isn't enforced by the langauge.

Wikipedia offers the following information on the subject:

Interestingly, the Java language specification regards const as a reserved keyword — i.e., one that cannot be used as variable identifier — but assigns no semantics to it. It is thought that the reservation of the keyword occurred to allow for an extension of the Java language to include C++-style const methods and pointer to const type. The enhancement request ticket in the Java Community Process for implementing const correctness in Java was closed in 2005, implying that const correctness will probably never find its way into the official Java specification.

Another option would be to use R via a small bash wrapper for convenience:

xlsx2txt(){
echo '
require(xlsx)
write.table(read.xlsx2(commandArgs(TRUE)[1], 1), stdout(), quote=F, row.names=FALSE, col.names=T, sep="\t")
' | Rscript --vanilla - $1 2>/dev/null
}

xlsx2txt file.xlsx > file.txt

This happens because of the way the windows paths interact. Your 32-bit JRE is listed BEFORE your 64-bit version. Since javaw.exe is named the same for both 32 and 64 bit versions, it tries the first one it finds. Change the order in your Path Environmental variables, so the 64-bit version higher on the list than the 32-bit, and it will work correctly.

Objects are passed by reference in PHP 5 and by value in PHP 4. Variables are passed by value by default!

To expand on persistent's answer, and to provide more of the functionality of NUnit, you can do this:

public bool AssertThrows<TException>(
    Action action,
    Func<TException, bool> exceptionCondition = null)
    where TException : Exception
{
    try
    {
        action();
    }
    catch (TException ex)
    {
        if (exceptionCondition != null)
        {
            return exceptionCondition(ex);
        }
        return true;
    }
    catch
    {
        return false;
    }

    return false;
}

Examples:

// No exception thrown - test fails.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => {}));

// Wrong exception thrown - test fails.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new ApplicationException(); }));

// Correct exception thrown - test passes.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new InvalidOperationException(); }));

// Correct exception thrown, but wrong message - test fails.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new InvalidOperationException("ABCD"); },
        ex => ex.Message == "1234"));

// Correct exception thrown, with correct message - test passes.
Assert.IsTrue(
    AssertThrows<InvalidOperationException>(
        () => { throw new InvalidOperationException("1234"); },
        ex => ex.Message == "1234"));

It took me a while to combine everything, make it a bit secure, and have it work with Gmail. I hope this answer saves someone some time.

Create a file with the encrypted server password:

In Powershell, enter the following command (replace myPassword with your actual password):

"myPassword" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "C:\EmailPassword.txt"

Create a powershell script (Ex. sendEmail.ps1):

$User = "[email protected]"
$File = "C:\EmailPassword.txt"
$cred=New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, (Get-Content $File | ConvertTo-SecureString)
$EmailTo = "[email protected]"
$EmailFrom = "[email protected]"
$Subject = "Email Subject" 
$Body = "Email body text" 
$SMTPServer = "smtp.gmail.com" 
$filenameAndPath = "C:\fileIwantToSend.csv"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
$SMTPMessage.Attachments.Add($attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($cred.UserName, $cred.Password); 
$SMTPClient.Send($SMTPMessage)

Automate with Task Scheduler:

Create a batch file (Ex. emailFile.bat) with the following:

powershell -ExecutionPolicy ByPass -File C:\sendEmail.ps1

Create a task to run the batch file. Note: you must have the task run with the same user account that you used to encrypted the password! (Aka, probably the logged in user)

That's all; you now have a way to automate and schedule sending an email and an attachment with Windows Task Scheduler and Powershell. No 3rd party software and the password is not stored as plain text (though granted, not terribly secure either).

You can also read this article on the level of security this provides for your email password.

I succefully just did this :

$json = str_replace("\u0022","\\\\\"",json_encode( $phpArray,JSON_HEX_QUOT)); 

json_encode() by default will escape " to \" . But it's still wrong JSON for json.PARSE(). So by adding option JSON_HEX_QUOT, json_encode() will replace " with \u0022. json.PARSE() still will not like \u0022. So then we need to replace \u0022 with \\". The \\\\\" is escaped \\".

NOTE : you can add option JSON_HEX_APOS to replace single quote with unicode HEX value if you have javascript single quote issue.

ex: json_encode( $phpArray, JSON_HEX_APOS|JSON_HEX_QUOT ));

Reversed one:

function decodeHtml(text) {
    return text
        .replace(/&/g, '&')
        .replace(/&lt;/ , '<')
        .replace(/&gt;/, '>')
        .replace(/&quot;/g,'"')
        .replace(/&#039;/g,"'");
}

Android OnItemClickLIstener conflicts with the OnClickListener of items of row of listview in Adapter. You just have to make sure your code is well managed and properly written with standards.

Check the answer in the link given below:

Make list clickable

mozilla still support base 64 URIs. This allows you to compose dynamically the binary content using javascript:

<a href="data:application/vnd.ms-excel<base64 encoded binary excel content here>"> download xls</a>

if your excel file is not very fancy (no diagrams, formulas, macroses) you can dig into the format and compose bytes for your file, then encode them with base64 and put in to the href

refer to https://developer.mozilla.org/en/data_URIs

If your column with DATE datatype has value like below : -

value in column : 10-NOV-2005 06:31:00

Then, You can Use TRUNC function in select query to convert your date-time value to only date like - DD/MM/YYYY or DD-MON-YYYY

select TRUNC(column_1) from table1;

result : 10-NOV-2005

You will see above result - Provided that NLS_DATE_FORMAT is set as like below :-

Alter session NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';

Some scripts give you what you're looking for. If the nodes are running Samba or Windows, nbstat.nse will show you the MAC address and vendor.

sudo nmap -sU -script=nbstat.nse -p137 --open 172.192.10.0/23 -oX 172.192.10.0.xml | grep MAC * | awk -F";" {'print $4'}

You can create an html page with a form, having method="post" and action="yourdesiredurl" and open it with your browser.

As an alternative, there are some browser plugins for developers that allow you to do that, like Web Developer Toolbar for Firefox

Follow the instructions at https://gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91 to set up the gcc version you need - gcc 5 or gcc 6 - on Ubuntu 14.04. The instructions include configuring update-alternatives to allow you to switch between versions as you need to.

Another simple solution, in windows, go to the file Homestead/Vagrantfile and add these lines to connect with a username/password instead of a private key:

config.ssh.username = "vagrant"  
config.ssh.password = "vagrant"  
config.ssh.insert_key = false 

So, finally part of the file will look like this :

if File.exists? homesteadYamlPath then
    settings = YAML::load(File.read(homesteadYamlPath))
elsif File.exists? homesteadJsonPath then
    settings = JSON.parse(File.read(homesteadJsonPath))
end

config.ssh.username = "vagrant"  
config.ssh.password = "vagrant"  
config.ssh.insert_key = false 

Homestead.configure(config, settings)

if File.exists? afterScriptPath then
    config.vm.provision "shell", path: afterScriptPath, privileged: false
end

Hope this help ..

Quicksort is usually the fastest on average, but It has some pretty nasty worst-case behaviors. So if you have to guarantee no bad data gives you O(N^2), you should avoid it.

Merge-sort uses extra memory, but is particularly suitable for external sorting (i.e. huge files that don't fit into memory).

Heap-sort can sort in-place and doesn't have the worst case quadratic behavior, but on average is slower than quicksort in most cases.

Where only integers in a restricted range are involved, you can use some kind of radix sort to make it very fast.

In 99% of the cases, you'll be fine with the library sorts, which are usually based on quicksort.

Setting CommandTimeout to 120 is not recommended. Try using pagination as mentioned above. Setting CommandTimeout to 30 is considered as normal. Anything more than that is consider bad approach and that usually concludes something wrong with the Implementation. Now the world is running on MiliSeconds Approach.

This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?

• Many providers support bearer tokens which are very weak security-wise. By making them short-lived and requiring refresh, they limit the time an attacker can abuse a stolen token.
• Large scale deployment don't want to perform a database lookup every API call, so instead they issue self-encoded access token which can be verified by decryption. However, this also means there is no way to revoke these tokens so they are issued for a short time and must be refreshed.
• The refresh token requires client authentication which makes it stronger. Unlike the above access tokens, it is usually implemented with a database lookup.

This method will return the selected value for the drop down,

public static String getSelected_visibleText(WebDriver driver, String elementType, String value)
  {
    WebElement element = Webelement_Finder.webElement_Finder(driver, elementType, value);
   Select Selector = new Select(element);
    Selector.getFirstSelectedOption();
    String textval=Selector.getFirstSelectedOption().getText();
    return textval;
  }

Meanwhile

String textval=Selector.getFirstSelectedOption();

element.getText();

Will return all the elements in the drop down.

With jQuery, it is possible, however not using ajax.

function LoadPage(){
  $.get('http://a_site.com/a_page.html', function(data) {
    $('#siteloader').html(data);
  });
}

And then place onload="LoadPage()" in the body tag.

Although if you follow this route, a php version might be better:

echo htmlspecialchars(file_get_contents("some URL"));

I had the same problem. The problem is with context. If you want to open any links (for example share any link through chooser) pass activity context, not application context.

Dont forget to add myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK) if you are not in your activity.

You can find the answer here: Is there a minlength validation attribute in HTML5?

Therefore this should do the job:

Updated Answer

Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)

Instead, the best approach would be to:

1. Allow each panel to toggle individually
2. Then, enforce the accordion behavior manually where appropriate.

To allow each panel to toggle individually, on the data-toggle="collapse" element, set the data-target attribute to the .collapse panel ID selector (instead of setting the data-parent attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.

Roughly, each panel should look like this:

<div class="panel panel-default">
   <div class="panel-heading">
         <h4 class="panel-title"
             data-toggle="collapse" 
             data-target="#collapseOne">
             Collapsible Group Item #1
         </h4>
    </div>
    <div id="collapseOne" 
         class="panel-collapse collapse">
        <div class="panel-body"></div>
    </div>
</div>

To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:

$('#accordion').on('show.bs.collapse', function () {
    if (active) $('#accordion .in').collapse('hide');
});

Then use show and hide to toggle the visibility of each of the panels and data-toggle to enable and disable the controls.

$('#collapse-init').click(function () {
    if (active) {
        active = false;
        $('.panel-collapse').collapse('show');
        $('.panel-title').attr('data-toggle', '');
        $(this).text('Enable accordion behavior');
    } else {
        active = true;
        $('.panel-collapse').collapse('hide');
        $('.panel-title').attr('data-toggle', 'collapse');
        $(this).text('Disable accordion behavior');
    }
});

@Alex aw that's a bummer. What if in your iframe you had an html document that looked like:

<html>
  <head>
    <meta http-equiv="refresh" content="0;url=/pdfs/somepdf.pdf" />
  </head>
  <body>
  </body>
</html>

Definitely a hack, but it might work for Firefox. Although I wonder if the load event would fire too soon in that case.

Example: Getting app_name string:

Resources.getSystem().getString( R.string.app_name )

Solution for Kotlin:

apply below code after setting "recyclerView.adapter" or after "recyclerView.adapter.notifyDataSetChanged()"

recyclerView.scrollToPosition(recyclerView.adapter.itemCount - 1)

My comment might not be relevant to the tags given. However, I was lead to this page from my search. I was looking for similar check in R and I came up the following with the help of @hugovdbeg post. I hope it would be helpful for someone who is looking for similar solution in R

You can have multiple exclude options for tar so

$ tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz .

etc will work. Make sure to put --exclude before the source and destination items.

For Java 8 the following method works:

1. Form an URI from file URI string
2. Create a file from the URI (not directly from URI string, absolute URI string are not paths)

Refer, below code snippet

    String fileURiString="file:///D:/etc/MySQL.txt";
    URI fileURI=new URI(fileURiString);
    File file=new File(fileURI);//File file=new File(fileURiString) - will generate exception

    FileInputStream fis=new FileInputStream(file);
    fis.close();

Run cmd.exe as an administrator then type:

python -m pip install

Here's what I did to solve this problem

• Close Android Studio
• Quick Start -> Check out from Version Control

I do it like this, but perhaps it's only ASP.NET MVC 4

@ViewContext.RouteData.Values["controller"]

This is a cheat, but you can do this, send the value to sever side as a parameter

<script>
var myVar = "hello"
window.location.href = window.location.href.replace(/[\?#].*|$/, "?param=" + myVar); //Send the variable to the server side
</script>

And from the server side, retrieve the parameter

string myVar = Request.QueryString["param"];
Session["SessionName"] = myVar;

hope this helps

I was able to fix the problem with changing column widths. I started with Andrew's solution above (thanks so much!) and then added one little loop to set the widths of the cloned td's:

$("#header-fixed td").each(function(index){
    var index2 = index;
    $(this).width(function(index2){
        return $("#table-1 td").eq(index).width();
    });
});

This solves the problem without having to clone the entire table and hide the body. I'm brand new to JavaScript and jQuery (and to stack overflow), so any comments are appreciated.

$ThatTime ="14:08:10";
if (time() >= strtotime($ThatTime)) {
  echo "ok";
}

A solution using DateTime (that also regards the timezone).

$dateTime = new DateTime($ThatTime);
if ($dateTime->diff(new DateTime)->format('%R') == '+') {
  echo "OK";
}

You are not reading the properties file correctly. The propertySource should pass the parameter as: file:appclient.properties or classpath:appclient.properties. Change the annotation to:

@PropertySource(value={"classpath:appclient.properties"})

However I don't know what your PropertiesConfig file contains, as you're importing that also. Ideally the @PropertySource annotation should have been kept there.

Since version 4.14 of Linux kernel, vfs_read and vfs_write functions are no longer exported for use in modules. Instead, functions exclusively for kernel's file access are provided:

ssize_t kernel_read(struct file *file, void *buf, size_t count, loff_t *pos);

# Write the file from the kernel space.
ssize_t kernel_write(struct file *file, const void *buf, size_t count,
            loff_t *pos);

Also, filp_open no longer accepts user-space string, so it can be used for kernel access directly (without dance with set_fs).

Easier solution;

#/bin/bash
if (( ${1:-2} >= 2 )); then
    echo "First parameter must be 0 or 1"
fi
# rest of script...

Output

$ ./test 
First parameter must be 0 or 1
$ ./test 0
$ ./test 1
$ ./test 4
First parameter must be 0 or 1
$ ./test 2
First parameter must be 0 or 1

Explanation

• (( )) - Evaluates the expression using integers.
• ${1:-2} - Uses parameter expansion to set a value of 2 if undefined.
• >= 2 - True if the integer is greater than or equal to two 2.

EDIT: If you are using a Dockerfile for deployments these are the steps you need to take to resolve this issue.

Change your Dockerfile to include the following:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
ENV PATH $PATH:/root/.dotnet/tools
RUN dotnet tool install -g dotnet-ef --version 3.1.1

Also change your dotnet ef commands to be dotnet-ef

Just add those lines on your custom css mycss.css

table tbody .ui-widget-content {
    background: none repeat scroll 0 0 #FFFFFF;
    border: 0 solid #FFFFFF;
    color: #333333;
}

Here is a good table for printf specifiers. So it should be %hu for unsigned short int.

And link to Wikipedia "C data types" too.

function DeleteJob() {
    if (confirm("Do you really want to delete selected job/s?"))
        window.location.href = "/{controller}/{action}/{params}";
    else
        return false;
}

UPDATE
    Table_A
SET
    Table_A.col1 = Table_B.col1,
    Table_A.col2 = Table_B.col2
FROM
    Some_Table AS Table_A
    INNER JOIN Other_Table AS Table_B
        ON Table_A.id = Table_B.id
WHERE
    Table_A.col3 = 'cool'

</script> has to be broken up because otherwise it would end the enclosing <script></script> block too early. Really it should be split between the < and the /, because a script block is supposed (according to SGML) to be terminated by any end-tag open (ETAGO) sequence (i.e. </):

Although the STYLE and SCRIPT elements use CDATA for their data model, for these elements, CDATA must be handled differently by user agents. Markup and entities must be treated as raw text and passed to the application as is. The first occurrence of the character sequence "</" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.

However in practice browsers only end parsing a CDATA script block on an actual </script> close-tag.

In XHTML there is no such special handling for script blocks, so any < (or &) character inside them must be &escaped; like in any other element. However then browsers that are parsing XHTML as old-school HTML will get confused. There are workarounds involving CDATA blocks, but it's easiest simply to avoid using these characters unescaped. A better way of writing a script element from script that works on either type of parser would be:

<script type="text/javascript">
    document.write('\x3Cscript type="text/javascript" src="foo.js">\x3C/script>');
</script>

Here's how I think you make a POST request with data and a cookie using just the node http library. This example is posting JSON, set your content-type and content-length accordingly if you post different data.

// NB:- node's http client API has changed since this was written
// this code is for 0.4.x
// for 0.6.5+ see http://nodejs.org/docs/v0.6.5/api/http.html#http.request

var http = require('http');

var data = JSON.stringify({ 'important': 'data' });
var cookie = 'something=anything'

var client = http.createClient(80, 'www.example.com');

var headers = {
    'Host': 'www.example.com',
    'Cookie': cookie,
    'Content-Type': 'application/json',
    'Content-Length': Buffer.byteLength(data,'utf8')
};

var request = client.request('POST', '/', headers);

// listening to the response is optional, I suppose
request.on('response', function(response) {
  response.on('data', function(chunk) {
    // do what you do
  });
  response.on('end', function() {
    // do what you do
  });
});
// you'd also want to listen for errors in production

request.write(data);

request.end();

What you send in the Cookie value should really depend on what you received from the server. Wikipedia's write-up of this stuff is pretty good: http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_attributes

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

JQuery Mobile has multipage feature. But I am not sure about Desktop Web Applications.

I can see only 1 things happening here: You did't set properly dependences to thelibrary.lib in your project meaning that thelibrary.lib is built in the wrong order (Or in the same time if you have more then 1 CPU build configuration, which can also explain randomness of the error). ( You can change the project dependences in: Menu->Project->Project Dependencies )

All the properties of your object are private. aka... not available outside their class's scope.

Solution for PHP >= 5.4

Use the new JsonSerializable Interface to provide your own json representation to be used by json_encode

class Thing implements JsonSerializable {
    ...
    public function jsonSerialize() {
        return [
            'something' => $this->something,
            'protected_something' => $this->get_protected_something(),
            'private_something' => $this->get_private_something()
        ];
    }
    ...
}

Solution for PHP < 5.4

If you do want to serialize your private and protected object properties, you have to implement a JSON encoding function inside your Class that utilizes json_encode() on a data structure you create for this purpose.

class Thing {
    ...
    public function to_json() {
        return json_encode(array(
            'something' => $this->something,
            'protected_something' => $this->get_protected_something(),
            'private_something' => $this->get_private_something()                
        ));
    }
    ...
}

A more detailed writeup

select month(dateField), year(dateField)

When opening a CSV, you get the text import wizard. At the last step of the wizard, you should be able to import the specific column as text, thereby retaining the '00' prefix. After that you can then format the cell any way that you want.

I tried with with Excel 2007 and it appeared to work.

I just faced this issue myself and I just removed it by removing the origin. the origin is removed by this command

git remove rm origin

try implementing this command.
