There is collection of Func<...>
classes - Func that is probably what you are looking for:
void MyMethod(Func<int> param1 = null)
This defines method that have parameter param1
with default value null
(similar to AS), and a function that returns int
. Unlike AS in C# you need to specify type of the function's arguments.
So if you AS usage was
MyMethod(function(intArg, stringArg) { return true; })
Than in C# it would require param1
to be of type Func<int, siring, bool>
and usage like
MyMethod( (intArg, stringArg) => { return true;} );
The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n
, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n
on input, and conversely on output.
From the C99 standard (the N869 draft document), §7.19.2/2,
A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.
And in §7.19.3/2
Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.
About use of fseek
, in §7.19.9.2/4:
For a text stream, either
offset
shall be zero, oroffset
shall be a value returned by an earlier successful call to theftell
function on a stream associated with the same file andwhence
shall beSEEK_SET
.
About use of ftell
, in §17.19.9.4:
The
ftell
function obtains the current value of the file position indicator for the stream pointed to bystream
. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by thefseek
function for returning the file position indicator for the stream to its position at the time of theftell
call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.
I think that’s the most important, but there are some more details.
I got the same issue (asp, c# - HttpPostedFileBase) when posting a file that was larger than 1MB (even though application doesn't have any limitation for file size), for me the simplification of model class helped. If you got this issue, try to remove some parts of the model, and see if it will help in any way. Sounds strange, but worked for me.

Open angular.json file and find budgets
keyword.
It should look like:
"budgets": [
{
"type": "initial",
"maximumWarning": "2mb",
"maximumError": "5mb"
}
]
As you’ve probably guessed you can increase the maximumWarning
value to prevent this warning, i.e.:
"budgets": [
{
"type": "initial",
"maximumWarning": "4mb", <===
"maximumError": "5mb"
}
]
A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.
In our case budget is the limit for bundle sizes.

Don't do like this,
MethodName _methodName;
Do like this,
MethodName _methodName = MethodName();
A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.
For example, say I have a Union like this:
type CatNames = "miffy" | "boris" | "mordred";
Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.
type CatList = Record<CatNames, {age: number}>
If I want to satisfy this CatList, I must create an object like this:
const cats:CatList = {
miffy: { age:99 },
boris: { age:16 },
mordred: { age:600 }
}
You get very strong type safety:
I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes
I had a union like this:
type Statuses = "failed" | "complete";
I used this to create an object like this:
const icons: Record<
Statuses,
{ iconType: IconTypes; iconColor: IconColors }
> = {
failed: {
iconType: "warning",
iconColor: "red"
},
complete: {
iconType: "check",
iconColor: "green"
};
I could then render by destructuring an element from the object into props, like so:
const Status = ({status}) => <Icon {...icons[status]} />
If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.
Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.
Run the Gradle build with a command line argument --warning-mode=all
to see what exactly the deprecated features are.
It will give you a detailed description of found issues with links to the Gradle docs for instructions how to fix your build.
Adding --stacktrace
to that, you will also be able to pinpoint where the warning comes from, if it's triggered by outdated code in one of the plugins and not your build script.

react-scripts
is a set of scripts from the create-react-app
starter pack. create-react-app helps you kick off projects without configuring, so you do not have to setup your project by yourself.
react-scripts start
sets up the development environment and starts a server, as well as hot module reloading. You can read here to see what everything it does for you.
with create-react-app you have following features out of the box.
- React, JSX, ES6, and Flow syntax support.
- Language extras beyond ES6 like the object spread operator.
- Autoprefixed CSS, so you don’t need -webkit- or other prefixes.
- A fast interactive unit test runner with built-in support for coverage reporting.
- A live development server that warns about common mistakes.
- A build script to bundle JS, CSS, and images for production, with hashes and sourcemaps.
- An offline-first service worker and a web app manifest, meeting all the Progressive Web App criteria.
- Hassle-free updates for the above tools with a single dependency.
npm start
is a shortcut for npm run start
.
npm run
is used to run scripts that you define in the scripts
object of your package.json
if there is no start
key in the scripts object, it will default to node server.js
Sometimes you want to do more than the react scripts gives you, in this case you can do react-scripts eject
. This will transform your project from a "managed" state into a not managed state, where you have full control over dependencies, build scripts and other configurations.
Normally you are going to do this in your template with FormGroup, Reactive Forms, etc...
this.myForm = this.fb.group({
title: ['', Validators.required],
description: ['', Validators.required],
isPublished: ['false',Validators.required]
});
You can simply use setInterval
to create such timer in Angular, Use this Code for timer -
timeLeft: number = 60;
interval;
startTimer() {
this.interval = setInterval(() => {
if(this.timeLeft > 0) {
this.timeLeft--;
} else {
this.timeLeft = 60;
}
},1000)
}
pauseTimer() {
clearInterval(this.interval);
}
<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>
<p>{{timeLeft}} Seconds Left....</p>
import { timer } from 'rxjs';
observableTimer() {
const source = timer(1000, 2000);
const abc = source.subscribe(val => {
console.log(val, '-');
this.subscribeTimer = this.timeLeft - val;
});
}
<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

To access an Ip Camera, first, I recommend you to install it like you are going to use for the standard application, without any code, using normal software.
After this, you have to know that for different cameras, we have different codes. There is a website where you can see what code you can use to access them:
https://www.ispyconnect.com/sources.aspx
But be careful, for my camera (Intelbras S3020) it does not work. The right way is to ask the company of your camera, and if they are a good company they will provide it.
When you know your code just add it like:
cap = cv2.VideoCapture("http://LOGIN:PASSWORD@IP/cgi-bin/mjpg/video.cgi?&subtype=1")
Instead LOGIN you will put your login, and instead PASSWORD you will put your password.
To find out camera's IP address there is many softwares that you can download and provide the Ip address to you. I use the software from Intelbras, but I also recommend EseeCloud because they work for almost all cameras that I've bought:
https://eseecloud.software.informer.com/1.2/
In this example, it shows the protocol http to access the Ip camera, but you can also use rstp, it depends on the camera, as I said.
If you have any further questions just let me know.
If we need to move from one component to another service then we have to define that service into app.module providers array.
Update your build.gradle(Module:app) add compileOptions
block and add JavaVersion.VERSION_1_8
apply plugin: 'com.android.application'
android {
.................
.........................
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
In this example, nothing really. The exact
param comes into play when you have multiple paths that have similar names:
For example, imagine we had a Users
component that displayed a list of users. We also have a CreateUser
component that is used to create users. The url for CreateUsers
should be nested under Users
. So our setup could look something like this:
<Switch>
<Route path="/users" component={Users} />
<Route path="/users/create" component={CreateUser} />
</Switch>
Now the problem here, when we go to http://app.com/users
the router will go through all of our defined routes and return the FIRST match it finds. So in this case, it would find the Users
route first and then return it. All good.
But, if we went to http://app.com/users/create
, it would again go through all of our defined routes and return the FIRST match it finds. React router does partial matching, so /users
partially matches /users/create
, so it would incorrectly return the Users
route again!
The exact
param disables the partial matching for a route and makes sure that it only returns the route if the path is an EXACT match to the current url.
So in this case, we should add exact
to our Users
route so that it will only match on /users
:
<Switch>
<Route exact path="/users" component={Users} />
<Route path="/users/create" component={CreateUser} />
</Switch>
I don't know if this is useful for someone, but in my case the problem was that the name had different casing.
V1
in the service configuration - V
capital letter
v1
in Settings -- v
lower case
The only thing I did was to use the same casing and it worked.
Two very different types of Pipes Angular - Pipes and RxJS - Pipes
A pipe takes in data as input and transforms it to a desired output. In this page, you'll use pipes to transform a component's birthday property into a human-friendly date.
import { Component } from '@angular/core';
@Component({
selector: 'app-hero-birthday',
template: `<p>The hero's birthday is {{ birthday | date }}</p>`
})
export class HeroBirthdayComponent {
birthday = new Date(1988, 3, 15); // April 15, 1988
}
Observable operators are composed using a pipe method known as Pipeable Operators. Here is an example.
import {Observable, range} from 'rxjs';
import {map, filter} from 'rxjs/operators';
const source$: Observable<number> = range(0, 10);
source$.pipe(
map(x => x * 2),
filter(x => x % 3 === 0)
).subscribe(x => console.log(x));
The output for this in the console would be the following:
0
6
12
18
For any variable holding an observable, we can use the .pipe() method to pass in one or multiple operator functions that can work on and transform each item in the observable collection.
So this example takes each number in the range of 0 to 10, and multiplies it by 2. Then, the filter function to filter the result down to only the odd numbers.
Unlike it's most popular commercial competitor, numpy pretty much from the outset is about "arbitrary-dimensional" arrays, that's why the core class is called ndarray
. You can check the dimensionality of a numpy array using the .ndim
property. The .shape
property is a tuple of length .ndim
containing the length of each dimensions. Currently, numpy can handle up to 32 dimensions:
a = np.ones(32*(1,))
a
# array([[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[ 1.]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]])
a.shape
# (1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
a.ndim
# 32
If a numpy array happens to be 2d like your second example, then it's appropriate to think about it in terms of rows and columns. But a 1d array in numpy is truly 1d, no rows or columns.
If you want something like a row or column vector you can achieve this by creating a 2d array with one of its dimensions equal to 1.
a = np.array([[1,2,3]]) # a 'row vector'
b = np.array([[1],[2],[3]]) # a 'column vector'
# or if you don't want to type so many brackets:
b = np.array([[1,2,3]]).T
import angularFirebaseStore
in app.module.ts
and set it as a provider like service

python -m pip install --upgrade pip
more example :
python -m pip install --upgrade selenium
python -m pip install --upgrade requests
...
simple way is to move your files to be read under the same folder of your python file, then you just need to use the name of the file, without calling another path.
Just add to @Bert's solution to make it more clear:
const routes = [
{ path: '/foo', component: Foo },
{ path: '/bar', component: Bar }
]
const router = new VueRouter({
routes,
linkExactActiveClass: "active" // active class for *exact* links.
})
As one can see, this line should be removed:
linkActiveClass: "active", // active class for non-exact links.
this way, ONLY the current link is hi-lighted. This should apply to most of the cases.

<Route exact path="/details/:id" render={(props)=>{return(
<DetailsPage id={props.match.params.id}/>)

Note This answer only applies to version 2.x of Vue. Version 3 has lifted this restriction.
You have two root elements in your template.
<div class="form-group">
...
</div>
<div class="col-md-6">
...
</div>
And you need one.
<div>
<div class="form-group">
...
</div>
<div class="col-md-6">
...
</div>
</div>
Essentially in Vue you must have only one root element in your templates.
use ResponseEntity<ResponseBean>
Here you can use ResponseBean or Any java bean as you like to return your api response and it is the best practice. I have used Enum for response. it will return status code and status message of API.
@GetMapping(path = "/login")
public ResponseEntity<ServiceStatus> restApiExample(HttpServletRequest request,
HttpServletResponse response) {
String username = request.getParameter("username");
String password = request.getParameter("password");
loginService.login(username, password, request);
return new ResponseEntity<ServiceStatus>(ServiceStatus.LOGIN_SUCCESS,
HttpStatus.ACCEPTED);
}
for response ServiceStatus or(ResponseBody)
public enum ServiceStatus {
LOGIN_SUCCESS(0, "Login success"),
private final int id;
private final String message;
//Enum constructor
ServiceStatus(int id, String message) {
this.id = id;
this.message = message;
}
public int getId() {
return id;
}
public String getMessage() {
return message;
}
}
Spring REST API should have below key in response
you will get final response below
{
"StatusCode" : "0",
"Message":"Login success"
}
you can use ResponseBody(java POJO, ENUM,etc..) as per your requirement.
Don't use with Router.
handleSubmit(e){
e.preventDefault();
this.props.form.validateFieldsAndScroll((err,values)=>{

this.setState({

this.props.form.resetFields();

const path = '/list/';
this.props.history.push(path);
}
})
}
It works well.
I had 2 files (and 2 classes) in the same project with the same name.
var is a variable like any other language. eg.
var price: Double
On the other side, val provides you feature of referencing. eg.
val CONTINENTS = 7
// You refer this to get constant value 7. In this case, val acts as access
// specifier final in Java
and,
val Int.absolute: Int
get() {
return Math.abs(this)
}
// You refer to the newly create 'method' which provides absolute value
// of your integer
println(-5.absolute) // O.P: 5
I had missing application context in the Tomcat Run\Debug configuration:

I realize this post is a few years old, but I just wanted to extend this to anyone still struggling through this issue.
The company I work for still uses VS2015 so in turn I still use VS2015. I recently started working on a RPC application using C++ and found the need to download the Win32 Templates. Like many others I was having this "SDK 8.1 was not found" issue. i took the following corrective actions with no luck.
None of the attempts above corrected the issue for me...
I then found this article on social MSDN https://social.msdn.microsoft.com/Forums/office/en-US/5287c51b-46d0-4a79-baad-ddde36af4885/visual-studio-cant-find-windows-81-sdk-when-trying-to-build-vs2015?forum=visualstudiogeneral
Finally what resolved the issue for me was:
I hope this saves anyone else from almost 3 full days of frustration and loss of productivity.
Then apart from these 4, we have
foldByKey which is same as reduceByKey but with a user defined Zero Value.
AggregateByKey takes 3 parameters as input and uses 2 functions for merging(one for merging on same partitions and another to merge values across partition. The first parameter is ZeroValue)
whereas
ReduceBykey takes 1 parameter only which is a function for merging.
CombineByKey takes 3 parameter and all 3 are functions. Similar to aggregateBykey except it can have a function for ZeroValue.
GroupByKey takes no parameter and groups everything. Also, it is an overhead for data transfer across partitions.
For me, I missed this statement in @Component decorator: animations: [yourAnimation]
Once I added this statement, errors gone. (Angular 6.x)
Heres how I solved it with React and Typescript. Hope it helps !

If you want to add plots to your Jupyter notebook, then %matplotlib inline
is a standard solution. And there are other magic commands will use matplotlib
interactively within Jupyter.
%matplotlib
: any plt
plot command will now cause a figure window to open, and further commands can be run to update the plot. Some changes will not draw automatically, to force an update, use plt.draw()
%matplotlib notebook
: will lead to interactive plots embedded within the notebook, you can zoom and resize the figure
%matplotlib inline
: only draw static images in the notebook
FOR V3, although it may work for V4. Going off of Eric's answer, I needed to do a little more, like handle local development where 'http' is not present on the url. I'm also redirecting to another application on the same server.
Added to router file:
import RedirectOnServer from './components/RedirectOnServer';
<Route path="/somelocalpath"
component={RedirectOnServer}
target="/someexternaltargetstring like cnn.com"
/>
And the Component:
import React, { Component } from "react";
export class RedirectOnServer extends Component {
constructor(props) {
super();
//if the prefix is http or https, we add nothing
let prefix = window.location.host.startsWith("http") ? "" : "http://";
//using host here, as I'm redirecting to another location on the same host
this.target = prefix + window.location.host + props.route.target;
}
componentDidMount() {
window.location.replace(this.target);
}
render(){
return (
<div>
<br />
<span>Redirecting to {this.target}</span>
</div>
);
}
}
export default RedirectOnServer;
Just had this problem with visual studio being unable to find my tests, couldn't see the button to run them besides the method, and they weren't picked up by running all tests in the project.
Turns out my test class wasn't public! Making it public allowed VS to discover the tests.
Open the external library of your project you will see that some library still using previous version although you didn't mention those library so my suggestion is just use the particular library version for those it will solve your problem.
That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null
or undefined
here, so don't complain about the possibility of it being null
or undefined
." Sometimes the type checker is unable to make that determination itself.
It is explained here:
A new
!
post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operationx!
produces a value of the type ofx
withnull
andundefined
excluded. Similar to type assertions of the forms<T>x
andx as T
, the!
non-null assertion operator is simply removed in the emitted JavaScript code.
I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.
install it from terminal
sudo apt-get install php-intl
Just as a normal js object:
let myhash: IHash = {};
myhash["somestring"] = "value"; //set
let value = myhash["somestring"]; //get
There are two things you're doing with [indexer: string] : string
You can make a general dictionary with explicitly typed fields by using [key: string]: any;
e.g. age
must be number
, while name
must be a string - both are required. Any implicit field can be any type of value.
As an alternative, there is a Map
class:
let map = new Map<object, string>();
let key = new Object();
map.set(key, "value");
map.get(key); // return "value"
This allows you have any Object instance (not just number/string) as the key.
Although its relatively new so you may have to polyfill it if you target old systems.
For the record, the spring.jpa.hibernate.ddl-auto
property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto
.
The values create
, create-drop
, validate
, and update
basically influence how the schema tool management will manipulate the database schema at startup.
For example, the update
operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.
The update
operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.
Typically in test case scenarios, you'll likely use create-drop
so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.
In development, it's often common to see developers use update
to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.
In production, it's often highly recommended you use none
or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.
Some thing like this.

To avoid having to type additional .catch(function () {})
in your code in multiple places, you could add a decorator
to the $exceptionHandler
.
This is a more verbose option than the others but you only have to make the change in one place.
angular
.module('app')
.config(configDecorators);
configDecorators.$inject = ["$provide"];
function configDecorators($provide) {
$provide.decorator("$exceptionHandler", exceptionHandler);
exceptionHandler.$inject = ['$delegate', '$injector'];
function exceptionHandler($delegate, $injector) {
return function (exception, cause) {
if ((exception.toString().toLowerCase()).includes("Possibly unhandled rejection".toLowerCase())) {
console.log(exception); /* optional to log the "Possibly unhandled rejection" */
return;
}
$delegate(exception, cause);
};
}
};
On 2/22/18, when I tried the official recommendation:

I want to know how to check whether MySQL strict mode is on or off in localhost(xampp).
SHOW VARIABLES LIKE 'sql_mode';
If result has "STRICT_TRANS_TABLES", then it's ON. Otherwise, it's OFF.
If on then for what modes and how to off.
If off then how to on.
For Windows,
C:\Program Files\MariaDB XX.X\data
my.ini
file.SHOW VARIABLES LIKE 'sql_mode'
again to see if it worked;*3.a. To turn it ON, add STRICT_TRANS_TABLES
on that line like this: sql_mode=STRICT_TRANS_TABLES
. *If there are other values already, add a comma after this then join with the rest of the value.
*3.b. To turn it OFF, simply remove STRICT_TRANS_TABLES
from value. *Remove the additional comma too if there is one.
**6. To restart the MySQL service on your computer,
services.msc
OK

Restart
What you are looking for is a simple directive like:
location ~* \.(?:manifest|appcache|html?|xml|json)$ {
expires -1;
}
The above will not cache the extensions within the (). You can configure different directives for different file types.
The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.
If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.
Move your code from ngAfterViewInit to ngAfterContentInit
An observable allows you to subscribe only whereas a subject allows you to both publish and subscribe.
So a subject allows your services to be used as both a publisher and a subscriber.
As of now, I'm not so good at Observable
so I'll share only an example of Subject
.
Let's understand better with an Angular CLI example. Run the below commands:
npm install -g @angular/cli
ng new angular2-subject
cd angular2-subject
ng serve
Replace the content of app.component.html
with:
<div *ngIf="message">
{{message}}
</div>
<app-home>
</app-home>
Run the command ng g c components/home
to generate the home component. Replace the content of home.component.html
with:
<input type="text" placeholder="Enter message" #message>
<button type="button" (click)="setMessage(message)" >Send message</button>
#message
is the local variable here. Add a property message: string;
to the app.component.ts
's class.
Run this command ng g s service/message
. This will generate a service at src\app\service\message.service.ts
. Provide this service to the app.
Import Subject
into MessageService
. Add a subject too. The final code shall look like this:
import { Injectable } from '@angular/core';
import { Subject } from 'rxjs/Subject';
@Injectable()
export class MessageService {
public message = new Subject<string>();
setMessage(value: string) {
this.message.next(value); //it is publishing this value to all the subscribers that have already subscribed to this message
}
}
Now, inject this service in home.component.ts
and pass an instance of it to the constructor. Do this for app.component.ts
too. Use this service instance for passing the value of #message
to the service function setMessage
:
import { Component } from '@angular/core';
import { MessageService } from '../../service/message.service';
@Component({
selector: 'app-home',
templateUrl: './home.component.html',
styleUrls: ['./home.component.css']
})
export class HomeComponent {
constructor(public messageService:MessageService) { }
setMessage(event) {
console.log(event.value);
this.messageService.setMessage(event.value);
}
}
Inside app.component.ts
, subscribe and unsubscribe (to prevent memory leaks) to the Subject
:
import { Component, OnDestroy } from '@angular/core';
import { MessageService } from './service/message.service';
import { Subscription } from 'rxjs/Subscription';
@Component({
selector: 'app-root',
templateUrl: './app.component.html'
})
export class AppComponent {
message: string;
subscription: Subscription;
constructor(public messageService: MessageService) { }
ngOnInit() {
this.subscription = this.messageService.message.subscribe(
(message) => {
this.message = message;
}
);
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
That's it.
Now, any value entered inside #message
of home.component.html
shall be printed to {{message}}
inside app.component.html
This is a really quick & detailed solution
Open the Terminal and execute the following to get the latest stable version:
sudo gem install cocoapods
Add --pre to get the latest pre release:
sudo gem install cocoapods --pre
Incase any error occured
Try uninstall and install again:
sudo gem uninstall cocoapods
sudo gem install cocoapods
Run after updating CocoaPods
sudo gem clean cocoapods
After updating CocoaPods, also need to update Podfile.lock file in your project.
Go to your project directory
pod install
Just In case: while using the command line to generate the SHA1 fingerprint, be careful while specifying the folder path. If your User Name or android folder path has a space, you should add two double quotes as below:
keytool -list -v -keystore "C:\Users\User Name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
<>
is equal to !=
i.e, both are used to represent the NOT EQUAL operation. For instance, email <> ''
and email != ''
are same.
If you are using RC5 then import this:
import { CommonModule } from '@angular/common';
import { BrowserModule } from '@angular/platform-browser';
and be sure to import CommonModule
from the module that is providing your component.
@NgModule({
imports: [CommonModule],
declarations: [MyComponent]
...
})
class MyComponentModule {}
You can use input type="reset"
<form action="/action_page.php">
text: <input type="text" name="email" /><br />
<input type="reset" defaultValue="Reset" />
</form>
$invoice = "Jul-16"
[datetime]$newInvoice = "01-" + $invoice
$newInvoice.ToString("yyyy-MM-dd")
There you go, use a type accelerator, but also into a new var, if you want to use it elsewhere, use it like so: $newInvoice.ToString("yyyy-MM-dd")
as $newInvoice
will always be in the datetime format, unless you cast it as a string afterwards, but will lose the ability to perform datetime functions - adding days etc...
I also have this issue and have been looking into it for a long time. It seems that there is no such problem on python 3+. The problem is actually on google.protobuf
pip uninstall protobuf
pip uninstall google
pip install google
pip install protobuf
pip install google-cloud
create an __init__.py
in "google" folder.
cd /path/to/your/env/lib/python2.7/site-packages/google
touch __init__.py
Hopefully it will work.
To set all FormGroup values use, setValue:
this.myFormGroup.setValue({
formControlName1: myValue1,
formControlName2: myValue2
});
To set only some values, use patchValue:
this.myFormGroup.patchValue({
formControlName1: myValue1,
// formControlName2: myValue2 (can be omitted)
});
With this second technique, not all values need to be supplied and fields whos values were not set will not be affected.
You can use dtype=np.int64
instead of dtype=int
This Question was asked here: VBA Arrays - Check strict (not approximative) match
Sub test()
vars1 = Array("Examples")
vars2 = Array("Example")
If IsInArray(Range("A1").value, vars1) Then
x = 1
End If
If IsInArray(Range("A1").value, vars2) Then
x = 1
End If
End Sub
Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
IsInArray = Not IsError(Application.Match(stringToBeFound, arr, 0))
End Function
I strongly recommend the method extract the column 'Pollutants':
df_pollutants = pd.DataFrame(df['Pollutants'].values.tolist(), index=df.index)
it's much faster than
df_pollutants = df['Pollutants'].apply(pd.Series)
when the size of df is giant.
To check mongodb version use the mongod command with --version
option.
To check MongoDB Server version, Open the command line via your terminal program and execute the following command:
Path :
C:\Program Files\MongoDB\Server\3.2\bin
Open Cmd and
execute the following command:
mongod --version
To Check MongoDB Shell version, Type:
mongo --version
You will have a server key something like this AIzaSyDiTEVq4Li1pj7IyraRlyRU9adc-49-KVY available in the Settings section of firebase console console.firebase.google.com/project/project-XXXXXXXXXXXXX/settings/cloudmessaging.
Specify the correct key with your code and try again.
When we create a customer directive, the scope of the directive could be in Isolated scope, It means the directive does not share a scope with the controller; both directive and controller have their own scope. However, data can be passed to the directive scope in three possible ways.
@
string literal, pass string value, one way binding.=
string literal, pass object, 2 ways binding.&
string literal, calls external function, can pass data from directive to controller.From what I can see there are helper methods inside the ControllerBase
class. Just use the StatusCode
method:
[HttpPost]
public IActionResult Post([FromBody] string something)
{
//...
try
{
DoSomething();
}
catch(Exception e)
{
LogException(e);
return StatusCode(500);
}
}
You may also use the StatusCode(int statusCode, object value)
overload which also negotiates the content.
FirebaseInstanceIdService is now deprecated. you should get the Token in the onNewToken method in the FirebaseMessagingService.
Or you can use reject
method
$newColection = $collection->reject(function($element) {
return $item->selected != true;
});
or pull
method
$selected = [];
foreach ($collection as $key => $item) {
if ($item->selected == true) {
$selected[] = $collection->pull($key);
}
}
You can access component one's method from component two..
componentOne
ngOnInit() {}
public testCall(){
alert("I am here..");
}
componentTwo
import { oneComponent } from '../one.component';
@Component({
providers:[oneComponent ],
selector: 'app-two',
templateUrl: ...
}
constructor(private comp: oneComponent ) { }
public callMe(): void {
this.comp.testCall();
}
componentTwo html file
<button (click)="callMe()">click</button>
This is working for me, you might change your code like this
var responseData=x.toString();
to
var responseData=x.toString("binary");
and finally
response.write(new Buffer(toTransmit, "binary"));
According to the documentation:
$validator = Validator::make($request->all(), [
'file' => 'max:500000',
]);
The value is in kilobytes. I.e. max:10240
= max 10 MB.
The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory.
Please see the error below:
Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO)
which points to username
not getting populated
.
Please recheck system properties
dataSource.setUsername(System.getProperty("root"));
some packages seems to be missing as well pointing to a dependency issue:
package org.gjt.mm.mysql does not exist
Please run a mvn dependency:tree
command to check for dependencies
As if you want your app to run in > 24 versions too, follow these:
1.Add this in your strings.xml
< string name="default_notification_channel_id" translatable="false"> fcm_default_channel
< meta-data android:name="com.google.firebase.messaging.default_notification_channel_id" android:value="@string/default_notification_channel_id" />
3.for creating notifications (with images) use this method where you are handling notifications, if directly then add in the firebasemessaging service or if you are using some util class then add in that util class :
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
public static void createBigNotification(Bitmap bitmap, int icon, String message, Uri alarmSound) {
final int NOTIFY_ID = 0; // ID of notification
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(NOTIFICATION_SERVICE);
String id = mContext.getString(R.string.default_notification_channel_id); // default_channel_id
String title = mContext.getString(R.string.app_name);
Intent intent;
NotificationCompat.Builder builder;
if (notificationManager == null) {
notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
}
PendingIntent resultPendingIntent;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = notificationManager.getNotificationChannel(id);
if (mChannel == null) {
mChannel = new NotificationChannel(id, title, importance);
mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
notificationManager.createNotificationChannel(mChannel);
}
builder = new NotificationCompat.Builder(mContext, id);
intent = new Intent(mContext, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
resultPendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
bigPictureStyle.setBigContentTitle(title);
bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
bigPictureStyle.bigPicture(bitmap);
builder.setContentTitle(title) // required
.setSmallIcon(R.drawable.app_icon) // required
.setContentText(message) // required
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setSound(alarmSound)
.setStyle(bigPictureStyle)
.setContentIntent(resultPendingIntent)
.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
.setTicker(title)
.setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
} else {
builder = new NotificationCompat.Builder(mContext, id);
intent = new Intent(mContext, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
resultPendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
bigPictureStyle.setBigContentTitle(title);
bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
bigPictureStyle.bigPicture(bitmap);
builder.setContentTitle(title) // required
.setSmallIcon(R.drawable.app_icon) // required
.setContentText(message) // required
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setSound(alarmSound)
.setStyle(bigPictureStyle)
.setContentIntent(resultPendingIntent)
.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
.setTicker(title)
.setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
.setPriority(Notification.PRIORITY_HIGH);
}
Notification notification = builder.build();
notificationManager.notify(NOTIFY_ID, notification);
}
Follow these steps and your notification will come in the notification tray.
The Conclusion I can make is
1) We can do UI design without touching the xml part of code, to be honest I feel google has copied how UI is designed in iOS apps, it will make sense if you are familiar with UI development in iOS, but in relative layout its hard to set the constraints without touching the xml design.
2) Secondly it has flat view hierarchy unlike other layouts, so does better performance than relative layout which you might have seen from other answers
3) It also have extra things apart from what relative layout has, such as circular relative positioning where we can position another view relative to this one at certain radius with certain angle which cant do in relative layout
I am saying it again, designing UI using constraint layout is same as designing UI in iOS, so in future if you work on iOS you will find it easier if you have used constraint layout
This worked for me: run
sudo lsof -i :<port_number>
after that it will display the PID which is currently attached to the process.
After that run sudo kill -9 <PID>
if that doesn't work, try the solution offered by user8376606 it would definitely work!
guys. I had the same problem before when I'm trying import a .aar package into my project, and unfortunately before make the .aar package as a module-dependence of my project, I had two modules (one about ROS-ANDROID-CV-BRIDGE, one is OPENCV-FOR-ANDROID) already. So, I got this error as you guys meet:
Error:Could not find method android() for arguments [org.ros.gradle_plugins.RosAndroidPlugin$_apply_closure2_closure4@7e550e0e] on project ‘:xxx’ of type org.gradle.api.Project.
So, it's the painful gradle-structure caused this problem when you have several modules in your project, and worse, they're imported in different way or have different types (.jar/.aar packages or just a project of Java library). And it's really a headache matter to make the configuration like compile-version, library dependencies etc. in each subproject compatible with the main-project.
I solved my problem just follow this steps:
? Copy .aar package in app/libs.
? Add this in app/build.gradle file:
repositories {
flatDir {
dirs 'libs' //this way we can find the .aar file in libs folder
}
}
? Add this in your add build.gradle file of the module which you want to apply the .aar dependence (in my situation, just add this in my app/build.gradle file):
dependencies {
compile(name:'package_name', ext:'aar')
}
So, if it's possible, just try export your module-dependence as a .aar package, and then follow this way import it to your main-project. Anyway, I hope this can be a good suggestion and would solve your problem if you have the same situation with me.
To return true or false depending on whether a checkbox is checked or not, I use this in JQuery
let checkState = $("#checkboxId").is(":checked") ? "true" : "false";
One possible solution would to use regex.
'phone' => 'required|regex:/(01)[0-9]{9}/'
This will check the input starts with 01 and is followed by 9 numbers. By using regex you don't need the numeric
or size
validation rules.
If you want to reuse this validation method else where, it would be a good idea to create your own validation rule for validating phone numbers.
In your AppServiceProvider
's boot
method:
Validator::extend('phone_number', function($attribute, $value, $parameters)
{
return substr($value, 0, 2) == '01';
});
This will allow you to use the phone_number
validation rule anywhere in your application, so your form validation could be:
'phone' => 'required|numeric|phone_number|size:11'
In your validator extension you could also check if the $value
is numeric and 11 characters long.
Great New Application
No Need to root your Phone and You Can Run your js File From anywere.
Update instruction to node js 8 (async await)
Download node.js v8.3.0 arm zip file and unzip.
copy 'node' to android's sdcard(/sdcard or /sdcard/path/to/...)
open the shell(check it out in the app's menu)
cd /data/user/0/io.tmpage.dorynode/files/bin (or, just type cd && cd .. && cd files/bin )
rm node
cp /sdcard/node .
(chmod a+x node
(https://play.google.com/store/apps/details?id=io.tempage.dorynode&hl=en)
According to the doc about Run tests by node ids
since you have all node ids in foo.txt, just run
pytest `cat foo.txt | tr '\n' ' '`
this is same with below command (with file content in the question)
pytest tests_directory/foo.py::test_001 tests_directory/bar.py::test_some_other_test
Postgres hasn't implemented an equivalent to INSERT OR REPLACE
. From the ON CONFLICT
docs (emphasis mine):
It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.
Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE
applies more generally, since it lets you set new values based on preexisting data. For example:
INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;
There is no need to pass the entire event (unless you need other aspects of the event than you have stated). In fact, it is not recommended. You can pass the element reference with just a little modification.
import {Component} from 'angular2/core';
@Component({
selector: 'my-app',
template: `
<button #btn1 (click)="toggle(btn1)" class="someclass" id="btn1">Button 1</button>
<button #btn2 (click)="toggle(btn2)" class="someclass" id="btn2">Button 2</button>
`
})
export class AppComponent {
buttonValue: string;
toggle(button) {
this.buttonValue = button.id;
}
}
Technically, you don't need to find the button that was clicked, because you have passed the actual element.
You can achieve this using by a simple custom pipe.
import { Pipe, PipeTransform } from '@angular/core';
import { DatePipe } from '@angular/common';
@Pipe({
name: 'dateFormatPipe',
})
export class dateFormatPipe implements PipeTransform {
transform(value: string) {
var datePipe = new DatePipe("en-US");
value = datePipe.transform(value, 'dd/MM/yyyy');
return value;
}
}
{{currentDate | dateFormatPipe }}
Advantage of using a custom pipe is that, if you want to update the date format in future, you can go and update your custom pipe and it will reflect every where.

I just had the same problem and tested the methods mentioned above. After several trials, I realized that they are partially correct and are not the complete solution. I tested the below in Windows 10 and Anaconda 4.4.0 with python 3.6.
There are two ways to do even though they have only very small difference. Follow the way marneylc suggested above: i.e.
1) Open "Anaconda Prompt" and type jupyter notebook --generate-config
2) You find the file in C:\Users\username\.jupyter\jupyter_notebook_config.py
3) Change the line of #c.NotebookApp.notebook_dir = ''
to c.NotebookApp.notebook_dir = 'c:\test\your_root\'
4) Then, go to the shortcut of Jupyter Notebook located in C:\Users\User_name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit)
5) Do the right click and go to the Properties
6) In the Target
field, remove %USERPROFILE%
as stenlytw suggested above.
7) Then, In the field of Start in
, type the same directory of c:\test\your_root\
in jupyter_notebook_config.py
8) Done!
As the simpler way, after step 3, go to C:\Users\User_name\Anaconda3\Scripts
4-2) You can see the file of jupyter-notebook.exe
and click it.
5-2) Then, the Jupyter start the folder you specified in jupyter_notebook_config.py
. So make the shortcut of this file.
6-2) Done.
Existing code is working, but is blocking the thread.
.Select(async ev => await ProcessEventAsync(ev))
creates a new Task for every event, but
.Select(t => t.Result)
blocks the thread waiting for each new task to end.
In the other hand your code produce the same result but keeps asynchronous.
Just one comment on your first code. This line
var tasks = await Task.WhenAll(events...
will produce a single Task<TResult[]> so the variable should be named in singular.
Finally your last code make the same but is more succinct.
For reference: Task.Wait / Task.WhenAll
for me the "workaround" solution was to remove the "_normal" from the end of the string
Check it out below:
In my case it is Asp.Net Core 3.1 API. I changed the HTTP GET method from public ActionResult GetValidationRulesForField( GetValidationRulesForFieldDto getValidationRulesForFieldDto)
to public ActionResult GetValidationRulesForField([FromQuery] GetValidationRulesForFieldDto getValidationRulesForFieldDto)
and its working.
There is no need to download any binaries or files or follow difficult installation instructions.
All you really needed to do is:
sudo apt update && sudo apt install android-sdk
Update: Ubuntu 18.04 only
Another approach(Inside of $function
to asure that the each
is executed on document ready
):
var ids = [1,2];
$(function(){
$('.checkbox-wrapper>input[type="checkbox"]').each(function(i,item){
if(ids.indexOf($(item).data('id')) > -1){
$(item).prop("checked", "checked");
}
});
});
What is the n.fn.init[0], and why it is returned? Why are my two seemingly identical JQuery functions returning different things?
Answer: It seems that your elements are not in the DOM yet, when you are trying to find them. As @Rory McCrossan pointed out, the
length:0
means that it doesn't find any element based on your search criteria.
n.fn.init[0]
, lets look at the core of the Jquery Library:var jQuery = function( selector, context ) {
return new jQuery.fn.init( selector, context );
};
Looks familiar, right?, now in a minified version of jquery, this should looks like:
var n = function( selector, context ) {
return new n.fn.init( selector, context );
};
So when you use a selector you are creating an instance of the jquery function; when found an element based on the selector criteria it returns the matched elements; when the criteria does not match anything it returns the prototype object of the function.
With your own Code and a Slight Change withou jQuery,
function testingAPI(){
var key = "8a1c6a354c884c658ff29a8636fd7c18";
var url = "https://api.fantasydata.net/nfl/v2/JSON/PlayerSeasonStats/2015";
console.log(httpGet(url,key));
}
function httpGet(url,key){
var xmlHttp = new XMLHttpRequest();
xmlHttp.open( "GET", url, false );
xmlHttp.setRequestHeader("Ocp-Apim-Subscription-Key",key);
xmlHttp.send(null);
return xmlHttp.responseText;
}
Thank You
@Nullable
and @NotNull
do nothing on their own. They are supposed to act as Documentation tools.
The @Nullable
Annotation reminds you about the necessity to introduce an NPE check when:
The @NotNull
Annotation is, actually, an explicit contract declaring the following:
For example, instead of writing:
/**
* @param aX should not be null
*/
public void setX(final Object aX ) {
// some code
}
You can use:
public void setX(@NotNull final Object aX ) {
// some code
}
Additionally, @NotNull
is often checked by ConstraintValidators (eg. in spring and hibernate).
The @NotNull
annotation doesn't do any validation on its own because the annotation definition does not provide any ConstraintValidator
type reference.
For more info see:
You can use names
directly in the read_csv
names : array-like, default None List of column names to use. If file contains no header row, then you should explicitly pass header=None
Cov = pd.read_csv("path/to/file.txt",
sep='\t',
names=["Sequence", "Start", "End", "Coverage"])
The changelog is sloppily worded. from __future__ import absolute_import
does not care about whether something is part of the standard library, and import string
will not always give you the standard-library module with absolute imports on.
from __future__ import absolute_import
means that if you import string
, Python will always look for a top-level string
module, rather than current_package.string
. However, it does not affect the logic Python uses to decide what file is the string
module. When you do
python pkg/script.py
pkg/script.py
doesn't look like part of a package to Python. Following the normal procedures, the pkg
directory is added to the path, and all .py
files in the pkg
directory look like top-level modules. import string
finds pkg/string.py
not because it's doing a relative import, but because pkg/string.py
appears to be the top-level module string
. The fact that this isn't the standard-library string
module doesn't come up.
To run the file as part of the pkg
package, you could do
python -m pkg.script
In this case, the pkg
directory will not be added to the path. However, the current directory will be added to the path.
You can also add some boilerplate to pkg/script.py
to make Python treat it as part of the pkg
package even when run as a file:
if __name__ == '__main__' and __package__ is None:
__package__ = 'pkg'
However, this won't affect sys.path
. You'll need some additional handling to remove the pkg
directory from the path, and if pkg
's parent directory isn't on the path, you'll need to stick that on the path too.
In my case i have multiple product flavors. It used to work earlier. It stopped working after updating project gradle version to 4.0.1 and 'google-services:4.3.4'.
I got error like 'Task :app:processDebugGoogleServices FAILED' when i run the project.
I replaced 'google-services.json' in app module with 'my-product-flavor/google-services.json'. It is working fine now.
Additionally to the great answer of Erti-Chris Eelmaa - there's annoying window.navigator.webdriver
and it is read-only. Event if you change the value of it to false
it will still have true
. That's why the browser driven by automated software can still be detected.
The variable is managed by the flag --enable-automation
in chrome. The chromedriver launches Chrome with that flag and Chrome sets the window.navigator.webdriver
to true
. You can find it here. You need to add to "exclude switches" the flag. For instance (Go):
package main
import (
"github.com/tebeka/selenium"
"github.com/tebeka/selenium/chrome"
)
func main() {
caps := selenium.Capabilities{
"browserName": "chrome",
}
chromeCaps := chrome.Capabilities{
Path: "/path/to/chrome-binary",
ExcludeSwitches: []string{"enable-automation"},
}
caps.AddChrome(chromeCaps)
wd, err := selenium.NewRemote(caps, fmt.Sprintf("http://localhost:%d/wd/hub", 4444))
}
If you installed Jupiter notebook through anaconda, this may help you:
conda uninstall jupyter notebook
I had this problem even though my source directory was in the correct build context. Found the reason was that my source directory was a symbolic link to a location outside the build context.
For example my Dockerfile contains the following:
COPY dir1 /tmp
If dir1
is a symbolic link the COPY
command is not working in my case.
After messing around with @BringBackCommodore64 answer I figured it out
[link](file:///d:/absolute.md) # absolute filesystem path
[link](./relative1.md) # relative to opened file
[link](/relativeToProject.md) # relative to opened project
All of them tested in Visual Studio Code
and working,
Note: The absolute path works in editor but doesn't work in markdown preview mode!
I was also stuck in similar kind of situation, setLevel()
method was not coming, when I was trying to call it with the instance of HttpLoggingInterceptor,
like this:
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
Here is how I resolved it, to generate log for Retrofit2,
I suppose you have added the dependecy,
implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"
For the latest version you can check out, this link:
https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor )
Here they have also explained about how to add.
I created a class with name AddLoggingInterceptor
,
here is my code,
public class AddLoggingInterceptor {
public static OkHttpClient setLogging(){
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.addInterceptor(loggingInterceptor)
.build();
return okHttpClient;
}
}
Then, where we are instantiating our Retrofit,
public static Retrofit getRetrofitInstance() {
if (retrofit == null) {
retrofit = new retrofit2.Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(AddLoggingInterceptor.setLogging()) // here the method is called inside client() method, with the name of class, since it is a static method.
.build();
}
return retrofit;
}
Now you can see log generated in your Android Studio, you may need to search, okHttp
for filtering process. It worked for me. If any issues you can text me here.
Even if your data falls within your specified limits (e.g. c(0, 335)
), adding a geom_jitter()
statement could push some points outside those limits, producing the same error message.
library(ggplot2)
range(mtcars$hp)
#> [1] 52 335
# No jitter -- no error message
ggplot(mtcars, aes(mpg, hp)) +
geom_point() +
scale_y_continuous(limits=c(0,335))
# Jitter is too large -- this generates the error message
ggplot(mtcars, aes(mpg, hp)) +
geom_point() +
geom_jitter(position = position_jitter(w = 0.2, h = 0.2)) +
scale_y_continuous(limits=c(0,335))
#> Warning: Removed 1 rows containing missing values (geom_point).

Look up NR
and FNR
in the awk manual and then ask yourself what is the condition under which NR==FNR
in the following example:
$ cat file1
a
b
c
$ cat file2
d
e
$ awk '{print FILENAME, NR, FNR, $0}' file1 file2
file1 1 1 a
file1 2 2 b
file1 3 3 c
file2 4 1 d
file2 5 2 e
Sometimes you don't have a local REF for pushing that branch back to the origin.
Try

std::atomic
exists because many ISAs have direct hardware support for it
What the C++ standard says about std::atomic
has been analyzed in other answers.
So now let's see what std::atomic
compiles to to get a different kind of insight.
The main takeaway from this experiment is that modern CPUs have direct support for atomic integer operations, for example the LOCK prefix in x86, and std::atomic
basically exists as a portable interface to those intructions: What does the "lock" instruction mean in x86 assembly? In aarch64, LDADD would be used.
This support allows for faster alternatives to more general methods such as std::mutex
, which can make more complex multi-instruction sections atomic, at the cost of being slower than std::atomic
because std::mutex
it makes futex
system calls in Linux, which is way slower than the userland instructions emitted by std::atomic
, see also: Does std::mutex create a fence?
Let's consider the following multi-threaded program which increments a global variable across multiple threads, with different synchronization mechanisms depending on which preprocessor define is used.
main.cpp
#include <atomic>
#include <iostream>
#include <thread>
#include <vector>
size_t niters;
#if STD_ATOMIC
std::atomic_ulong global(0);
#else
uint64_t global = 0;
#endif
void threadMain() {
for (size_t i = 0; i < niters; ++i) {
#if LOCK
__asm__ __volatile__ (
"lock incq %0;"
: "+m" (global),
"+g" (i) // to prevent loop unrolling
:
:
);
#else
__asm__ __volatile__ (
""
: "+g" (i) // to prevent he loop from being optimized to a single add
: "g" (global)
:
);
global++;
#endif
}
}
int main(int argc, char **argv) {
size_t nthreads;
if (argc > 1) {
nthreads = std::stoull(argv[1], NULL, 0);
} else {
nthreads = 2;
}
if (argc > 2) {
niters = std::stoull(argv[2], NULL, 0);
} else {
niters = 10;
}
std::vector<std::thread> threads(nthreads);
for (size_t i = 0; i < nthreads; ++i)
threads[i] = std::thread(threadMain);
for (size_t i = 0; i < nthreads; ++i)
threads[i].join();
uint64_t expect = nthreads * niters;
std::cout << "expect " << expect << std::endl;
std::cout << "global " << global << std::endl;
}

Conclusions:
the non-atomic version saves the global to a register, and increments the register.
Therefore, at the end, very likely four writes happen back to global with the same "wrong" value of 100000
.
std::atomic
compiles to lock addq
. The LOCK prefix makes the following inc
fetch, modify and update memory atomically.
our explicit inline assembly LOCK prefix compiles to almost the same thing as std::atomic
, except that our inc
is used instead of add
. Not sure why GCC chose add
, considering that our INC generated a decoding 1 byte smaller.

LDAP is trying to authenticate with AD when sending a transaction to another server DB. This authentication fails because the user has recently changed her password, although this transaction was generated using the previous credentials. This authentication will keep failing until ... unless you change the transaction status to Complete or Cancel in which case LDAP will stop sending these transactions.

There is a lot of confusion here, especially if you read outdated sources.
The basic one is Activity
, which can show Fragments. You can use this combination if you're on Android version > 4.
However, there is also a support library which encompasses the other classes you mentioned: FragmentActivity
, ActionBarActivity
and AppCompat
. Originally they were used to support fragments on Android versions < 4, but actually they're also used to backport functionality from newer versions of Android (material design for example).
The latest one is AppCompat
, the other 2 are older. The strategy I use is to always use AppCompat
, so that the app will be ready in case of backports from future versions of Android.

In my humble opinion, I understand this question in this way:
[CASE 1] When you start an absolute-import like
python -m test_A.test
or
import test_A.test
or
from test_A import test
you're actually setting the import-anchor to be test_A
, in other word, top-level package is test_A
. So, when we have test.py do from ..A import xxx
, you are escaping from the anchor, and Python does not allow this.
[CASE 2] When you do
python -m package.test_A.test
or
from package.test_A import test
your anchor becomes package
, so package/test_A/test.py
doing from ..A import xxx
does not escape the anchor(still inside package
folder), and Python happily accepts this.
In short:
Furthermore, we can use full-qualified module name(FQMN) to inspect this problem.
Check FQMN in each case:
test.__name__
= package.test_A.test
test.__name__
= test_A.test
So, for CASE2, an from .. import xxx
will result in a new module with FQMN=package.xxx
, which is acceptable.
While for CASE1, the ..
from within from .. import xxx
will jump out of the starting node(anchor) of test_A
, and this is NOT allowed by Python.
I notice that recent Oracle client installers change file permissions.
I had Oracle 12.0.1 32 bit client installed for a year. I recently installed Oracle 12.0.1 64 bit client. The Oracle install change ALL file permissions in the 32 bit folders.
My application suddenly failed to run.
I used PROCMON.EXE (https://docs.microsoft.com/en-us/sysinternals/downloads/) and noticed that permission was denied opening OCI.DLL
I changed the permissions for everything in the Oracle client folders and application works as expected.
You don't directly read a value. You can set it with .setValue()
, but there is no .getValue() on the reference object.
You have to use a listener. If you just want to read the value once, you use ref.addListenerForSingleValueEvent()
.
Example:
Firebase ref = new Firebase("YOUR-URL-HERE/PATH/TO/YOUR/STUFF");
ref.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
String value = (String) dataSnapshot.getValue();
// do your stuff here with value
}
@Override
public void onCancelled(FirebaseError firebaseError) {
}
});

You need to convert the string to date using the to_date()
function
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');
This will work only if OrderDate
is stored in Date format
. If it is Varchar
you should apply to_date()
func on that column also like
SELECT * FROM OrderArchive
WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');
Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:
$contents = (string) $response->getBody();
You can also do it with
$contents = $response->getBody()->getContents();
The difference between the two approaches is that getContents
returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind
or seek
.
$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents
Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.
$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents

One possible explanation is a database trigger that fires for each DROP TABLE
statement. To find the trigger, query the _TRIGGERS
dictionary views:
select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')
disable any suspicious trigger with
alter trigger <trigger_name> disable;
and try re-running your DROP TABLE
statement
You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:
# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful
On Ubuntu/Debian you can configure headers in the file
/etc/apache2/conf-enabled/security.conf
#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"
#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"
Note: This is the bottom part of the file. Only the last three entries are CSP settings.
The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.
Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.
While you're at it you could take a look at the other header settings and install mod_security

You'll have to pass the new ordinal position to insert
using len
in this case:
In [62]:
a=[1,2,3,4]
a.insert(len(a),5)
a
Out[62]:
[1, 2, 3, 4, 5]

For this, I installed an extension called TabOut. Pretty much does what the name suggests.
I just wanted to share my experience with you if someone might has the same problem with MOODLE.
Our moodle platform was suddenly very slowly, the dashboard took about 2-3 times longer to load (up to 6 seconds) then usual and from time to time some pages didn't get loaded at all (not a 404 error but a blank page). In the Developer Tools Console the following error was visible: net::ERR_INCOMPLETE_CHUNKED_ENCODING.
Searching for this error, it looks like Chrome is the issue, but we had the problem with various browsers. After hours of research and comparing the databases from the days before I finally found the problem, someone turned the Event Monitoring on. However, in the "Config changes" log, this change wasn't visible! Turning Event Monitoring off, finally solved the problem - we had no rules defined for event monitoring.
We're running Moodle 3.1.2+ with MariaDB and PHP 5.4.
The answer by @akrun certainly does the trick. For future googlers who want to understand why, here is an explanation...
The new variable needs to be created first.
The variable "valueBin" needs to be already in the df in order for the conditional assignment to work. Essentially, the syntax of the code is correct. Just add one line in front of the code chuck to create this name --
df$newVariableName <- NA
Then you continue with whatever conditional assignment rules you have, like
df$newVariableName[which(df$oldVariableName<=250)] <- "<=250"
I blame whoever wrote that package's error message... The debugging was made especially confusing by that error message. It is irrelevant information that you have two arrays in the df with different lengths. No. Simply create the new column first. For more details, consult this post https://www.r-bloggers.com/translating-weird-r-errors/
let df
be the name of the Pandas DataFrame and any value that is numpy.nan
is a null value.
If you want to see which columns has nulls and which do not(just True and False)
df.isnull().any()
If you want to see only the columns that has nulls
df.loc[:, df.isnull().any()].columns
If you want to see the count of nulls in every column
df.isna().sum()
If you want to see the percentage of nulls in every column
df.isna().sum()/(len(df))*100
If you want to see the percentage of nulls in columns only with nulls:
df.loc[:,list(df.loc[:,df.isnull().any()].columns)].isnull().sum()/(len(df))*100
EDIT 1:
If you want to see where your data is missing visually:
import missingno
missingdata_df = df.columns[df.isnull().any()].tolist()
missingno.matrix(df[missingdata_df])
If you're using jackson, better to convert directly to ObjectNode.
//not including SerializationFeatures for brevity
static final ObjectMapper mapper = new ObjectMapper();
//pass it your payload
public static ObjectNode convObjToONode(Object o) {
StringWriter stringify = new StringWriter();
ObjectNode objToONode = null;
try {
mapper.writeValue(stringify, o);
objToONode = (ObjectNode) mapper.readTree(stringify.toString());
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(objToONode);
return objToONode;
}
The T
doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.
The Z
stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).
Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime()
method. You could have used Q
or M
or Monty Python
and the method would have returned them unchanged as well; the method only looks for patterns starting with %
to replace those with information from the datetime
object.
First you need to start karma server with
karma start
Then, you can use grep to filter a specific test or describe block:
karma run -- --grep=testDescriptionFilter
I had the same issue after update on Android Studio 3.2.1 I had to re-import project, after that everything works
Try This :) I created my on model of count all results
in library_model
function count_all_results($column_name = array(),$where=array(), $table_name = array())
{
$this->db->select($column_name);
// If Where is not NULL
if(!empty($where) && count($where) > 0 )
{
$this->db->where($where);
}
// Return Count Column
return $this->db->count_all_results($table_name[0]);//table_name array sub 0
}
Your Controller will look like this
public function my_method()
{
$data = array(
$countall = $this->model->your_method_model()
);
$this->load->view('page',$data);
}
Then Simple Call The Library Model In Your Model
function your_method_model()
{
return $this->library_model->count_all_results(
['id'],
['where],
['table name']
);
}
I reworked the example you provided in the js fiddle : http://jsfiddle.net/zravs3hp/
I renamed your container
div to overlay
, as semantically this div is not a container, but an overlay. I also placed the loader div as a child of this overlay div.
The resulting html is :
<div class="overlay">
<div id="loading-img"></div>
</div>
<div class="content">
<div>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ea velit provident sint aliquid eos omnis aperiam officia architecto error incidunt nemo obcaecati adipisci doloremque dicta neque placeat natus beatae cupiditate minima ipsam quaerat explicabo non reiciendis qui sit. ...</div>
<button id="button">Submit</button>
</div>
The css of the overlay is the following
.overlay {
background: #e9e9e9; <- I left your 'gray' background
display: none; <- Not displayed by default
position: absolute; <- This and the following properties will
top: 0; make the overlay, the element will expand
right: 0; so as to cover the whole body of the page
bottom: 0;
left: 0;
opacity: 0.5;
}
I added some dummy text so as to have something to overlay.
Then, in the click
handler we just need to show the overlay :
$("#button").click(function () {
$(".overlay").show();
});
If you need to set the user header string in the curl request, you can use the -H
option to set user agent like:
curl -H "user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36" http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Using a proxy tool like Charles Proxy really helps make short work of something like what you are asking. Here is what I do, using this SO page as an example (as of July 2015 using Charles version 3.10):
You now have a cURL request you can run in a terminal that will mirror the request your browser made. Here is what my request to this page looked like (with the cookie header removed):
curl -H "Host: stackoverflow.com" -H "Cache-Control: max-age=0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" -H "HTTPS: 1" -H "DNT: 1" -H "Referer: https://www.google.com/" -H "Accept-Language: en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4" -H "If-Modified-Since: Thu, 23 Jul 2015 20:31:28 GMT" --compressed http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome
I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.
I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.
It is neither an API nor a framework. It is just an architectural concept. You can find more details here.
I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.
EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.
It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).
Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.
Here is a tidyverse
option that might work depending on the data, and some caveats on its usage:
library(tidyverse)
starting_df %>%
rownames_to_column() %>%
gather(variable, value, -rowname) %>%
spread(rowname, value)
rownames_to_column()
is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column()
and replace rowname
with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths
sample data would be:
smiths %>%
gather(variable, value, -subject) %>%
spread(subject, value)
Using the example starting_df
with the tidyverse
approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths
data will not give that warning because all columns except for subject
are doubles.
The earlier answer using as.data.frame(t())
will convert everything to a factor
if there are mixed column types unless stringsAsFactors = FALSE
is added,
whereas the tidyverse
option converts everything to a character by default if
there are mixed column types.
Here is an option for people who use DataBinding
for RecyclerView
.
I have var recyclerViewState: Parcelable?
in my adapter. And I use a BindingAdapter
with a variation of @DawnYu's answer to set and update data in the RecyclerView
:
@BindingAdapter("items")
fun setRecyclerViewItems(
recyclerView: RecyclerView,
items: List<RecyclerViewItem>?
) {
var adapter = (recyclerView.adapter as? RecyclerViewAdapter)
if (adapter == null) {
adapter = RecyclerViewAdapter()
recyclerView.adapter = adapter
}
adapter.recyclerViewState = recyclerView.layoutManager?.onSaveInstanceState()
// the main idea is in this call with a lambda. It allows to avoid blinking on data update
adapter.submitList(items.orEmpty()) {
adapter.recyclerViewState?.let {
recyclerView.layoutManager?.onRestoreInstanceState(it)
}
}
}
Finally, the XML part looks like:
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/possible_trips_rv"
android:layout_width="match_parent"
android:layout_height="0dp"
app:items="@{viewState.yourItems}"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"/>
First of all, the annotation doesn't annotate List
. It annotates the method, just as RequestMapping
does. Your code is equivalent to
@RequestMapping(value="/orders", method=RequestMethod.GET)
@ResponseBody
public List<Account> accountSummary() {
return accountManager.getAllAccounts();
}
Now what the annotation means is that the returned value of the method will constitute the body of the HTTP response. Of course, an HTTP response can't contain Java objects. So this list of accounts is transformed to a format suitable for REST applications, typically JSON or XML.
The choice of the format depends on the installed message converters, on the values of the produces
attribute of the @RequestMapping
annotation, and on the content type that the client accepts (that is available in the HTTP request headers). For example, if the request says it accepts XML, but not JSON, and there is a message converter installed that can transform the list to XML, then XML will be returned.
You can try/catch PDOException
s (your configs could differ but the important part is the try/catch):
try {
$dbh = new PDO(
DB_TYPE . ':host=' . DB_HOST . ';dbname=' . DB_NAME . ';charset=' . DB_CHARSET,
DB_USER,
DB_PASS,
[
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES ' . DB_CHARSET . ' COLLATE ' . DB_COLLATE
]
);
} catch ( PDOException $e ) {
echo 'ERROR!';
print_r( $e );
}
The print_r( $e );
line will show you everything you need, for example I had a recent case where the error message was like unknown database 'my_db'
.
I don't think you want the data from your Request, I think you want the data from your Response. The two are different. Also you should build your response correctly in your controller.
Looking at the class in edit #2, I would make it look like this:
class XmlController extends Controller
{
public function index()
{
$content = Request::all();
return Response::json($content);
}
}
Once you've gotten that far you should check the content of your response in your test case (use print_r if necessary), you should see the data inside.
More information on Laravel responses here:
It's the null conditional operator. It basically means:
"Evaluate the first operand; if that's null, stop, with a result of null. Otherwise, evaluate the second operand (as a member access of the first operand)."
In your example, the point is that if a
is null
, then a?.PropertyOfA
will evaluate to null
rather than throwing an exception - it will then compare that null
reference with foo
(using string's ==
overload), find they're not equal and execution will go into the body of the if
statement.
In other words, it's like this:
string bar = (a == null ? null : a.PropertyOfA);
if (bar != foo)
{
...
}
... except that a
is only evaluated once.
Note that this can change the type of the expression, too. For example, consider FileInfo.Length
. That's a property of type long
, but if you use it with the null conditional operator, you end up with an expression of type long?
:
FileInfo fi = ...; // fi could be null
long? length = fi?.Length; // If fi is null, length will be null
Following are the steps to push Docker Image to Private Repository of DockerHub
1- First check Docker Images using command
docker images
2- Check Docker Tag command Help
docker tag help
3- Now Tag a name to your created Image
docker tag localImgName:tagName DockerHubUser\Private-repoName:tagName(tag name is optional. Default name is latest)
4- Before pushing Image to DockerHub Private Repo, first login to DockerHub using command
docker login [provide dockerHub username and Password to login]
5- Now push Docker Image to your private Repo using command
docker push [options] ImgName[:tag] e.g docker push DockerHubUser\Private-repoName:tagName
6- Now navigate to the DockerHub Private Repo and you will see Docker image is pushed on your private Repository with name written as TagName in previous steps
I have encountered this problem twice. First time I used VS 2013 and the second time I used VS 2015 with different solution. The first solution on VS 2013 and python 2.7 is:
SET VS90COMNTOOLS=%VS120COMNTOOLS%
Now, one year later, I have found an easier method to fix it. This time I use VS 2015 and python 3.4.
VS100COMNTOOLS
to the variable nameVS140COMNTOOLS
to the new variable.Now I'm sure you will ask some question what is the VSXXXCOMNTOOLS
and what should I do if I use VS2008 or other compiler.
There is a file python\Lib\distutils\msvc9compiler.py, beginning on line 216 we see
def find_vcvarsall(version):
"""Find the vcvarsall.bat file
At first it tries to find the productdir of VS 2010 in the registry. If
that fails it falls back to the VS100COMNTOOLS env var.
"""
It means that you must give the productdir of VS 2010 for it, so if you are using python 2.x and
Visual Studio 2010 (VS10):SET VS90COMNTOOLS=%VS100COMNTOOLS%
Visual Studio 2012 (VS11):SET VS90COMNTOOLS=%VS110COMNTOOLS%
Visual Studio 2013 (VS12):SET VS90COMNTOOLS=%VS120COMNTOOLS%
Visual Studio 2015 (VS15):SET VS90COMNTOOLS=%VS140COMNTOOLS%
or if you are using python 3.x and
Visual Studio 2010 (VS10):SET VS100COMNTOOLS=%VS100COMNTOOLS%
Visual Studio 2012 (VS11):SET VS100COMNTOOLS=%VS110COMNTOOLS%
Visual Studio 2013 (VS12):SET VS100COMNTOOLS=%VS120COMNTOOLS%
Visual Studio 2015 (VS15):SET VS100COMNTOOLS=%VS140COMNTOOLS%
And it's the same as adding a new system variable. See the second ways.
Update:Sometimes,it still doesn't work.Check your path,ensure that contains VSxxxCOMNTOOLS
You can access the timezone by the following script:
SELECT * FROM pg_timezone_names WHERE name = current_setting('TIMEZONE');
output will be :

abbrev - CET,
utc_offset- 01:00:00,
is_dst- false
Just found an article from Anand Mani Sankar wich shows a simple way of using nginx upstream proxy with docker composer.
Basically one must configure the instance linking and ports at the docker-compose file and update upstream at nginx.conf accordingly.
- Where does
user.id
go afterpassport.serializeUser
has been called?
The user id (you provide as the second argument of the done
function) is saved in the session and is later used to retrieve the whole object via the deserializeUser
function.
serializeUser
determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}
. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}
- We are calling
passport.deserializeUser
right after it where does it fit in the workflow?
The first argument of deserializeUser
corresponds to the key of the user object that was given to the done
function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc).
In deserializeUser
that key is matched with the in memory array / database or any data resource.
The fetched object is attached to the request object as req.user
Visual Flow
passport.serializeUser(function(user, done) {
done(null, user.id);
}); ¦

});
Make sure the Docker daemon is running:
service docker start
That fixed it for me!
The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5
. From the comment you put this needed to be declared elsewhere in your code
$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider
The error was because you are trying to execute a method that does not exist.
PS C:\Users\Matt> $md5 | gm
TypeName: System.Security.Cryptography.MD5CryptoServiceProvider

Clear Method void Clear()
ComputeHash Method byte[] ComputeHash(System.IO.Stream inputStream), byte[] ComputeHash(byte[] buffer), byte[] ComputeHash(byte[] buffer, int offset, ...
The .ComputeHash()
of $md5.ComputeHash()
was the null valued expression. Typing in gibberish would create the same effect.
PS C:\Users\Matt> $bagel.MakeMeABagel()
You cannot call a method on a null-valued expression.

PowerShell by default allows this to happen as defined its StrictMode
When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.
The design guidelines defines two sizes and unless there is a strong reason to deviate from using either, the size can be controlled with the fabSize
XML attribute of the FloatingActionButton
component.
Consider specifying using either app:fabSize="normal"
or app:fabSize="mini"
, e.g.:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_done_white_24px"
app:fabSize="mini" />
This Should Work Fine
SELECT * FROM product
WHERE pdate BETWEEN datetime('now', '-30 days') AND datetime('now', 'localtime')
I have not worked on my answer but the way I know it StaggridLayoutManager with no. of grid 1 can solve your problem as StaggridLayout will automatically adjust its height and width on the size of the content. if it works dont forget to check it as a right answer.Cheers..

This error happens when you are trying to show popUpWindow too early ,to fix it, give Id to main layout as main_layout
and use below code
Java:
findViewById(R.id.main_layout).post(new Runnable() {
public void run() {
popupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
}
});
Kotlin:
main_layout.post {
popupWindow?.showAtLocation(main_layout, Gravity.CENTER, 0, 0)
}

It seems that NestedScrollView
does solve the problem. I've tested using this layout:
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/dummy_text"
/>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
>
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.v7.widget.CardView>
</LinearLayout>
And it works without issues
From Wikipedia http://en.wikipedia.org/wiki/Berkeley_sockets#bind.28.29
connect():
The connect() system call connects a socket, identified by its file descriptor, to a remote host specified by that host's address in the argument list.
Certain types of sockets are connectionless, most commonly user datagram protocol sockets. For these sockets, connect takes on a special meaning: the default target for sending and receiving data gets set to the given address, allowing the use of functions such as send() and recv() on connectionless sockets.
connect() returns an integer representing the error code: 0 represents success, while -1 represents an error.
bind():
bind() assigns a socket to an address. When a socket is created using socket(), it is only given a protocol family, but not assigned an address. This association with an address must be performed with the bind() system call before the socket can accept connections to other hosts. bind() takes three arguments:
sockfd, a descriptor representing the socket to perform the bind on. my_addr, a pointer to a sockaddr structure representing the address to bind to. addrlen, a socklen_t field specifying the size of the sockaddr structure. Bind() returns 0 on success and -1 if an error occurs.
Examples: 1.)Using Connect
#include <stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <string.h>
int main(){
int clientSocket;
char buffer[1024];
struct sockaddr_in serverAddr;
socklen_t addr_size;
/*---- Create the socket. The three arguments are: ----*/
/* 1) Internet domain 2) Stream socket 3) Default protocol (TCP in this case) */
clientSocket = socket(PF_INET, SOCK_STREAM, 0);
/*---- Configure settings of the server address struct ----*/
/* Address family = Internet */
serverAddr.sin_family = AF_INET;
/* Set port number, using htons function to use proper byte order */
serverAddr.sin_port = htons(7891);
/* Set the IP address to desired host to connect to */
serverAddr.sin_addr.s_addr = inet_addr("192.168.1.17");
/* Set all bits of the padding field to 0 */
memset(serverAddr.sin_zero, '\0', sizeof serverAddr.sin_zero);
/*---- Connect the socket to the server using the address struct ----*/
addr_size = sizeof serverAddr;
connect(clientSocket, (struct sockaddr *) &serverAddr, addr_size);
/*---- Read the message from the server into the buffer ----*/
recv(clientSocket, buffer, 1024, 0);
/*---- Print the received message ----*/
printf("Data received: %s",buffer);
return 0;
}
2.)Bind Example:
int main()
{
struct sockaddr_in source, destination = {}; //two sockets declared as previously
int sock = 0;
int datalen = 0;
int pkt = 0;
uint8_t *send_buffer, *recv_buffer;
struct sockaddr_storage fromAddr; // same as the previous entity struct sockaddr_storage serverStorage;
unsigned int addrlen; //in the previous example socklen_t addr_size;
struct timeval tv;
tv.tv_sec = 3; /* 3 Seconds Time-out */
tv.tv_usec = 0;
/* creating the socket */
if ((sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP)) < 0)
printf("Failed to create socket\n");
/*set the socket options*/
setsockopt(sock, SOL_SOCKET, SO_RCVTIMEO, (char *)&tv, sizeof(struct timeval));
/*Inititalize source to zero*/
memset(&source, 0, sizeof(source)); //source is an instance of sockaddr_in. Initialization to zero
/*Inititalize destinaton to zero*/
memset(&destination, 0, sizeof(destination));
/*---- Configure settings of the source address struct, WHERE THE PACKET IS COMING FROM ----*/
/* Address family = Internet */
source.sin_family = AF_INET;
/* Set IP address to localhost */
source.sin_addr.s_addr = INADDR_ANY; //INADDR_ANY = 0.0.0.0
/* Set port number, using htons function to use proper byte order */
source.sin_port = htons(7005);
/* Set all bits of the padding field to 0 */
memset(source.sin_zero, '\0', sizeof source.sin_zero); //optional
/*bind socket to the source WHERE THE PACKET IS COMING FROM*/
if (bind(sock, (struct sockaddr *) &source, sizeof(source)) < 0)
printf("Failed to bind socket");
/* setting the destination, i.e our OWN IP ADDRESS AND PORT */
destination.sin_family = AF_INET;
destination.sin_addr.s_addr = inet_addr("127.0.0.1");
destination.sin_port = htons(7005);
//Creating a Buffer;
send_buffer=(uint8_t *) malloc(350);
recv_buffer=(uint8_t *) malloc(250);
addrlen=sizeof(fromAddr);
memset((void *) recv_buffer, 0, 250);
memset((void *) send_buffer, 0, 350);
sendto(sock, send_buffer, 20, 0,(struct sockaddr *) &destination, sizeof(destination));
pkt=recvfrom(sock, recv_buffer, 98,0,(struct sockaddr *)&destination, &addrlen);
if(pkt > 0)
printf("%u bytes received\n", pkt);
}
I hope that clarifies the difference
Please note that the socket type that you declare will depend on what you require, this is extremely important
You can use FFserver to stream a video using RTSP.
Just change console syntax to something like this:
ffmpeg -i space.mp4 -vcodec libx264 -tune zerolatency -crf 18 http://localhost:1234/feed1.ffm
Create a ffserver.config
file (sample) where you declare HTTPPort
, RTSPPort
and SDP stream. Your config file could look like this (some important stuff might be missing):
HTTPPort 1234
RTSPPort 1235
<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 2M
ACL allow 127.0.0.1
</Feed>
<Stream test1.sdp>
Feed feed1.ffm
Format rtp
Noaudio
VideoCodec libx264
AVOptionVideo flags +global_header
AVOptionVideo me_range 16
AVOptionVideo qdiff 4
AVOptionVideo qmin 10
AVOptionVideo qmax 51
ACL allow 192.168.0.0 192.168.255.255
</Stream>
With such setup you can watch the stream with i.e. VLC by typing:
rtsp://192.168.0.xxx:1235/test1.sdp
Here is the FFserver documentation.
Use npm/bower to install bootstrap if you want to recompile it/change less files/test. With grunt it would be easier to do this, as shown on http://getbootstrap.com/getting-started/#grunt. If you only want to add precompiled libraries feel free to manually include files to project.
No, you have to do this by yourself or use separate grunt tool. For example 'grunt-contrib-concat' How to concatenate and minify multiple CSS and JavaScript files with Grunt.js (0.3.x)
Kubernetes is an open source project that brings 'Google style' cluster management capabilities to the world of virtual machines, or 'on the metal' scenarios. It works very well with modern operating system environments (like CoreOS or Red Hat Atomic) that offer up lightweight computing 'nodes' that are managed for you. It is written in Golang and is lightweight, modular, portable and extensible. We (the Kubernetes team) are working with a number of different technology companies (including Mesosphere who curate the Mesos open source project) to establish Kubernetes as the standard way to interact with computing clusters. The idea is to reproduce the patterns that we see people needing to build cluster applications based on our experience at Google. Some of these concepts include:
So with Kubernetes alone you will have something that is simple, easy to get up-and-running, portable and extensible that adds 'cluster' as a noun to the things that you manage in the lightest weight manner possible. Run an application on a cluster, and stop worrying about an individual machine. In this case, cluster is a flexible resource just like a VM. It is a logical computing unit. Turn it up, use it, resize it, turn it down quickly and easily.
With Mesos, there is a fair amount of overlap in terms of the basic vision, but the products are at quite different points in their lifecycle and have different sweet spots. Mesos is a distributed systems kernel that stitches together a lot of different machines into a logical computer. It was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application run well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps. It is somewhat more heavy weight than the Kubernetes project, but is getting easier and easier to manage thanks to the work of folks like Mesosphere.
Now what gets really interesting is that Mesos is currently being adapted to add a lot of the Kubernetes concepts and to support the Kubernetes API. So it will be a gateway to getting more capabilities for your Kubernetes app (high availability master, more advanced scheduling semantics, ability to scale to a very large number of nodes) if you need them, and is well suited to run production workloads (Kubernetes is still in an alpha state).
When asked, I tend to say:
Kubernetes is a great place to start if you are new to the clustering world; it is the quickest, easiest and lightest way to kick the tires and start experimenting with cluster oriented development. It offers a very high level of portability since it is being supported by a lot of different providers (Microsoft, IBM, Red Hat, CoreOs, MesoSphere, VMWare, etc).
If you have existing workloads (Hadoop, Spark, Kafka, etc), Mesos gives you a framework that let's you interleave those workloads with each other, and mix in a some of the new stuff including Kubernetes apps.
Mesos gives you an escape valve if you need capabilities that are not yet implemented by the community in the Kubernetes framework.
The reason your attempt wasn't working, is because the two animations (fade-in and fade-out) were working against each other.
Right before an object became visible, it was still invisible and so the animation for fading-out would run. Then, the fraction of a second later when that same object had become visible, the fade-in animation would try to run, but the fade-out was still running. So they would work against each other and you would see nothing.
Eventually the object would become visible (most of the time), but it would take a while. And if you would scroll down by using the arrow-button at the button of the scrollbar, the animation would sort of work, because you would scroll using bigger increments, creating less scroll-events.

if ($(this).css("opacity")==0) {...}
. This makes sure the object is only faded in when the opacity
is 0
. Same goes for fading out. And this prevents the fade-in and fade-out from working against each other, because now there's ever only one of the two running at one time on an object..animate()
to .fadeTo()
. It's jQuery's specialized function for opacity, a lot shorter to write and probably lighter than animate..position()
to .offset()
. This always calculates relative to the body, whereas position is relative to the parent. For your case I believe offset is the way to go.$(window).height()
to $(window).innerHeight()
. The latter is more reliable in my experience.$(window).scroll();
. Now you can give all desired objects on the page the .fade
class, and objects that should be invisible at page-load, will be faded out immediately.#container
from both HTML and CSS, because (at least for this answer) it isn't necessary. (I thought maybe you needed the height:2000px
because you used .position()
instead of .offset()
, otherwise I don't know. Feel free of course to leave it in your code.)If you want opacity values other than 0
and 1

threshold
and for min/max
at the start of the function. In the rest of the function these variables are referenced. This way, if you ever want to change the values again, you only have to do it in one place.|| pageLoad
to the if-clause. This was necessary to make sure all objects are faded to the correct opacity on page-load. pageLoad
is a boolean that is send along as an argument when fade()
is invoked.function fade() {...}
, in order to be able to send along the pageLoad
boolean when the scroll-handler is invoked.Explanation:
The reason the code in your fiddle didn't work, is because the actual opacity values are always a little off from the value you set it to. So if you set the opacity to 0.3
, the actual value (in this case) is 0.300000011920929
. That's just one of those little bugs you have to learn along the way by trail and error. That's why this if-clause won't work: if ($(this).css("opacity") == 0.3) {...}
.
I added a threshold, to take that difference into account: == 0.3
becomes <= 0.31
.
(I've set the threshold to 0.01
, this can be changed of course, just as long as the actual opacity will fall between the set value and this threshold.)
The operators are now changed from ==
to <=
and >=
.
If you want to fade the elements based on their visible percentage, use the following code:
$(window).on("load",function() {_x000D_
function fade(pageLoad) {_x000D_
var windowTop=$(window).scrollTop(), windowBottom=windowTop+$(window).innerHeight();_x000D_

_x000D_
/* Fade element in/out based on its visible percentage */_x000D_
if (objectTop < windowTop) {_x000D_

i=1
while(i<100) {
b<-i
l<-c(l,b)
i=i+1
}
Java also does not use line numbers, which is a necessity for a GOTO function. Unlike C/C++, Java does not have goto statement, but java supports label. The only place where a label is useful in Java is right before nested loop statements. We can specify label name with break to break out a specific outer loop.
In Centos 7 default filesystem is xfs.
xfs file system support only extend not reduce. So if you want to resize the filesystem use xfs_growfs rather than resize2fs.
xfs_growfs /dev/root_vg/root
Note: For ext4 filesystem use
resize2fs /dev/root_vg/root
In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("now:", now)
count := 10
then := now.Add(time.Duration(-count) * time.Minute)
// if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
// then := now.Add(-10 * time.Minute)
fmt.Println("10 minutes ago:", then)
}
Produces:
now: 2009-11-10 23:00:00 +0000 UTC
10 minutes ago: 2009-11-10 22:50:00 +0000 UTC
Not to mention, you can also use time.Hour
or time.Second
instead of time.Minute
as per your needs.

Although I prefer @Francescu's way (using a struct with static properties), you can also define global constants and variables:
let someNotification = "TEST"
Note however that differently from local variables/constants and class/struct properties, globals are implicitly lazy, which means they are initialized when they are accessed for the first time.
Suggested reading: Global and Local Variables, and also Global variables in Swift are not variables
As others have said problem is that script is executed before the page (and in particular the target element) is loaded.
But I don't like the solution of reordering the content.
Preferred solution is to put an event handler on page onload event and set the Listener there. That will ensure the page and the target element is loaded before the assignment is executed. eg
<script>
function onLoadFunct(){
// set Listener here, also using suggested test for null
}
....
</script>
<body onload="onLoadFunct()" ....>
.....
You don't need quotes around the variable, so simply change this:
Get-ADComputer -Filter {name -like '$nameregex' -and Enabled -eq "true"}
into this:
Get-ADComputer -Filter {name -like $nameregex -and Enabled -eq "true"}
Note, however, that the scriptblock notation for filter statements is misleading, because the statement is actually a string, so it's better to write it as such:
Get-ADComputer -Filter "name -like '$nameregex' -and Enabled -eq 'true'"
And FTR: you're using wildcard matching here (operator -like
), not regular expressions (operator -match
).
You can use the Java enum TimeUnit
to perform your math and avoid any hard coded values. Then we can use String.format(String, Object...)
and a pair of StringBuilder
(s) as well as a DecimalFormat
to build the requested output. Something like,
Scanner scanner = new Scanner(System.in);
System.out.println("Please enter a number of seconds:");
String str = scanner.nextLine().replace("\\,", "").trim();
long secondsIn = Long.parseLong(str);
long dayCount = TimeUnit.SECONDS.toDays(secondsIn);
long secondsCount = secondsIn - TimeUnit.DAYS.toSeconds(dayCount);
long hourCount = TimeUnit.SECONDS.toHours(secondsCount);
secondsCount -= TimeUnit.HOURS.toSeconds(hourCount);
long minutesCount = TimeUnit.SECONDS.toMinutes(secondsCount);
secondsCount -= TimeUnit.MINUTES.toSeconds(minutesCount);
StringBuilder sb = new StringBuilder();
sb.append(String.format("%d %s, ", dayCount, (dayCount == 1) ? "day"
: "days"));
StringBuilder sb2 = new StringBuilder();
sb2.append(sb.toString());
sb2.append(String.format("%02d:%02d:%02d %s", hourCount, minutesCount,
secondsCount, (hourCount == 1) ? "hour" : "hours"));
sb.append(String.format("%d %s, ", hourCount, (hourCount == 1) ? "hour"
: "hours"));
sb.append(String.format("%d %s and ", minutesCount,
(minutesCount == 1) ? "minute" : "minutes"));
sb.append(String.format("%d %s.", secondsCount,
(secondsCount == 1) ? "second" : "seconds"));
System.out.printf("You entered %s seconds, which is %s (%s)%n",
new DecimalFormat("#,###").format(secondsIn), sb, sb2);
Which, when I enter 500000
outputs the requested (manual line break added for post) -
You entered 500,000 seconds, which is 5 days, 18 hours,
53 minutes and 20 seconds. (5 days, 18:53:20 hours)
If you are using Gradle as a build tool and you get this error when executing a Gradle task i.e TomcatRun take a look to my other answer to the same question
You need to bind init before initialization.
$('.slider-for').on('init', function(event, slick){
$(this).append('<div class="slider-count"><p><span id="current">1</span> von <span id="total">'+slick.slideCount+'</span></p></div>');
});
$('.slider-for').slick({
slidesToShow: 1,
slidesToScroll: 1,
arrows: true,
fade: true
});
$('.slider-for')
.on('afterChange', function(event, slick, currentSlide, nextSlide){
// finally let's do this after changing slides
$('.slider-count #current').html(currentSlide+1);
});
Bearer token is one or more repetition of alphabet, digit, "-" , "." , "_" , "~" , "+" , "/" followed by 0 or more "=".
RFC 6750 2.1. Authorization Request Header Field (Format is ABNF (Augmented BNF))
The syntax for Bearer credentials is as follows:
b64token = 1*( ALPHA / DIGIT /
"-" / "." / "_" / "~" / "+" / "/" ) *"="
credentials = "Bearer" 1*SP b64token
It looks like Base64 but according to Should the token in the header be base64 encoded?, it is not.
Digging a bit deeper in to "HTTP/1.1, part 7: Authentication"**, however, I see that b64token is just an ABNF syntax definition allowing for characters typically used in base64, base64url, etc.. So the b64token doesn't define any encoding or decoding but rather just defines what characters can be used in the part of the Authorization header that will contain the access token.
This fully addresses the first 3 items in the OP question's list. So I'm extending this answer to address the 4th question, about whether the token must be validated, so @mon feel free to remove or edit:
The authorizer is responsible for accepting or rejecting the http request. If the authorizer says the token is valid, it's up to you to decide what this means:
json.loads
will load a json string into a python dict
, json.dumps
will dump a python dict
to a json string, for example:
>>> json_string = '{"favorited": false, "contributors": null}'
'{"favorited": false, "contributors": null}'
>>> value = json.loads(json_string)
{u'favorited': False, u'contributors': None}
>>> json_dump = json.dumps(value)
'{"favorited": false, "contributors": null}'
So that line is incorrect since you are trying to load
a python dict
, and json.loads
is expecting a valid json string
which should have <type 'str'>
.
So if you are trying to load the json, you should change what you are loading to look like the json_string
above, or you should be dumping it. This is just my best guess from the given information. What is it that you are trying to accomplish?
Also you don't need to specify the u
before your strings, as @Cld mentioned in the comments.
If you use the procedural style, you have to provide both a connection and a string:
$name = mysqli_real_escape_string($conn, $name);
Only the object oriented version can be done with just a string:
$name = $link->real_escape_string($name);
The documentation should hopefully make this clear.
You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.
You have two options:
Grant write permissions to the folder to the user or group you log in with (myuser
), or change the ownership of the folder to the user, or
Disable a transfer to temporary file.
In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:
I did it this way and it worked for me like a charm.

If you have a hard time remembering the default values (I know I have...) here's a short extract from BalusC's answer:

Buying a new processor is one solution, but for some of us that means buying other components as well. Alternatively you could just buy an Android phone that supports your lowest target API level and run your apps off the phone. You can find some of those phones on Amazon, Ebay, craigslist for pennies (sometimes). Plus this grants you the benefit of actually running on the minimum hardware you intend to support. While this may be a bit slower than installing your app on an emulated system, it will probably save you money.

Havengard's answer doesn't seem to be strictly true. I've found that vw fills the viewport width, but doesn't account for the scrollbars. So, if your content is taller than the viewport (so that your site has a vertical scrollbar), then using vw results in a small horizontal scrollbar. I had to switch out width: 100vw
for width: 100%
to get rid of the horizontal scrollbar.
You need to use the await keyword when use async and your function return type should be generic Here is an example with return value:
public async Task<object> MethodName()
{
return await Task.FromResult<object>(null);
}
Here is an example with no return value:
public async Task MethodName()
{
await Task.CompletedTask;
}

Ok i finally managed to do it without using the --privileged mode.
I'm running on ubuntu server 14.04 and i'm using the latest cuda (6.0.37 for linux 13.04 64 bits).
Install nvidia driver and cuda on your host. (it can be a little tricky so i will suggest you follow this guide https://askubuntu.com/questions/451672/installing-and-testing-cuda-in-ubuntu-14-04)
ATTENTION : It's really important that you keep the files you used for the host cuda installation
We need to run docker daemon using lxc driver to be able to modify the configuration and give the container access to the device.
One time utilization :
sudo service docker stop
sudo docker -d -e lxc
Permanent configuration Modify your docker configuration file located in /etc/default/docker Change the line DOCKER_OPTS by adding '-e lxc' Here is my line after modification
DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4 -e lxc"
Then restart the daemon using
sudo service docker restart
How to check if the daemon effectively use lxc driver ?
docker info
The Execution Driver line should look like that :
Execution Driver: lxc-1.0.5
Here is a basic Dockerfile to build a CUDA compatible image.

First you need to identify your the major number associated with your device. Easiest way is to do the following command :
ls -la /dev | grep nvidia
If the result is blank, use launching one of the samples on the host should do the trick. The result should look like that As you can see there is a set of 2 numbers between the group and the date. These 2 numbers are called major and minor numbers (wrote in that order) and design a device. We will just use the major numbers for convenience.
Why do we activated lxc driver? To use the lxc conf option that allow us to permit our container to access those devices. The option is : (i recommend using * for the minor number cause it reduce the length of the run command)
--lxc-conf='lxc.cgroup.devices.allow = c [major number]:[minor number or *] rwm'
So if i want to launch a container (Supposing your image name is cuda).
docker run -ti --lxc-conf='lxc.cgroup.devices.allow = c 195:* rwm' --lxc-conf='lxc.cgroup.devices.allow = c 243:* rwm' cuda
Compare the length using lengthB and length function in oracle.
SELECT * FROM test WHERE length(sampletext) <> lengthb(sampletext)
In SpringBoot 2.1, I found another solution. Extend standard factory class method getTomcatWebServer. And then return it as a bean from anywhere.
public class CustomTomcatServletWebServerFactory extends TomcatServletWebServerFactory {
@Override
protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
System.setProperty("catalina.useNaming", "true");
tomcat.enableNaming();
return new TomcatWebServer(tomcat, getPort() >= 0);
}
}
@Component
public class TomcatConfiguration {
@Bean
public ConfigurableServletWebServerFactory webServerFactory() {
TomcatServletWebServerFactory factory = new CustomTomcatServletWebServerFactory();
return factory;
}
Loading resources from context.xml doesn't work though. Will try to find out.
It IS possible, using something like the below example that I put together with the help of work from (https://gist.github.com/bitinn/1700068a276fb29740a7) that didn't quite work on iOS 11:
Here's the modified code that works on iOS 11.03, please comment if it worked for you.

As long as you override equals()
on each key and value contained in the map, then m1.equals(m2)
should be reliable to check for maps equality.
The same result can be obtained also by comparing toString()
of each map as you suggested, but using equals()
is a more intuitive approach.
May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals()
. More details about this see here.
Take for example a framework or a library you're designing for other users, these users eventually will have a main function
in their code in order to execute their app. If the user directly imports a sub-package of your library's project then the init
of that sub-package will be called(once) first of all. The same for the root package of the library, etc...
There are many times when you may want a code block to be executed without the existence of a main func
, directly or not.
If you, as the developer of the imaginary library, import your library's sub-package that has an init
function, it will be called first and once, you don't have a main func
but you need to make sure that some variables, or a table, will be initialized before the calls of other functions.
A good thing to remember and not to worry about, is that:
the init
always execute once per application.
init
execution happens:
init
function of the "caller" package,main func
,var = [...] or cost = [...]
, When you import a package it will run all of its init functions, by order.
I'll will give a very good example of an init function. It will add mime types to a standard go's library named mime
and a package-level function will use the mime
standard package directly to get the custom mime types that are already be initialized at its init
function:
package mime
import (
"mime"
"path/filepath"
)
var types = map[string]string{

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.
In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.
The client code must set the withCredentials
property on the XMLHttpRequest
to true
in order to give permission.
However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials
header. Responding with this header to true
means that the server allows cookies (or other user credentials) to be included on cross-origin requests.
You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.
Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).
From the documentation (help copy-item -full
):
-force <SwitchParameter>
Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.
Required? false
Position? named
Default value False
Accept pipeline input? false
Accept wildcard characters? false
user225312's answer is correct:
A. To count number of characters in str
object, you can use len()
function:
>>> print(len('please anwser my question'))
25
B. To get memory size in bytes allocated to store str
object, you can use sys.getsizeof()
function
>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50
It gets complicated for Python 2.
A. The len()
function in Python 2 returns count of bytes allocated to store encoded characters in a str
object.
Sometimes it will be equal to character count:
>>> print(len('abc'))
3
But sometimes, it won't:
>>> print(len('???')) # String contains Cyrillic symbols
6
That's because str
can use variable-length encoding internally. So, to count characters in str
you should know which encoding your str
object is using. Then you can convert it to unicode
object and get character count:
>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols
3
B. The sys.getsizeof()
function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object
>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32
Unless you're using spaces in there, you should be able to use | wc -w
on the first line.
wc
is "Word Count", which simply counts the words in the input file. If you send only one line, it'll tell you the amount of columns.
Try placing it on your body
body {
height: 100%;
background-image: url(../img/bg.svg);
background-size:100% 100%;
-o-background-size: 100% 100%;
-webkit-background-size: 100% 100%;
background-size:cover;
}
How about:
Random generator = new Random();
int i = 10 - generator.nextInt(10);
You don't need ng-checked
when you use ng-model
. If you're performing CRUD on your HTML Form, just create a model for CREATE
mode that is consistent with your EDIT
mode during the data-binding:
$scope.dataModel = {
isItemSelected: true,
isApproved: true,
somethingElse: "Your default value"
}
$scope.dataModel = getFromDatabaseWithSameStructure()
Then whether EDIT
or CREATE
mode, you can consistently make use of your ng-model
to sync with your database.

I encourage you to read the Maven Book about multi-module (reactor) builds.
I meant in particular the following:
<parent>
<artifactId>xyz-application</artifactId>
<groupId>com.xyz</groupId>
<version>2.50.0.g</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>com.xyz</groupId>
<artifactId>xyz-Library</artifactId>
<version>2.50.0.g</version>
should be changed into. Here take care about the not defined version only in parent part it is defined.
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>xyz-application</artifactId>
<groupId>com.xyz</groupId>
<version>2.50.0.g</version>
</parent>
<groupId>com.xyz</groupId>
<artifactId>xyz-Library</artifactId>
This is a better link.

Change
test=substring(i,j,*s);
to
test=substring(i,j,s);
Also, you need to forward declare substring:
char *substring(int i,int j,char *ch);
int main // ...
You can use the append()
function to insert items into vectors or lists (dataframes are lists). Simply:
df <- data.frame(a=c(1,2), b=c(3,4), c=c(5,6))
df <- as.data.frame(append(df, list(d=df$b+df$c), after=2))
Or, if you want to specify the position by name use which
:
df <- as.data.frame(append(df, list(d=df$b+df$c), after=which(names(df)=="b")))
It adds a horizontal divider to anywhere in your layout.
<TextView
style="?android:listSeparatorTextViewStyle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
This works for me
$('.someclass').click(function() {
$varName = $(this).data('fulltext');
console.log($varName);
});
If your machine is connected to the internet, going to smallestdotnet, downloading and executing the .NET Checker is probably the easiest way.
If you need the actual method to deterine the version look at its source on github, esp. the Constants.cs which will help you for .net 4.5 and later, where the Revision part is the relvant one:
{ int.MinValue, "4.5" },
{ 378389, "4.5" },
{ 378675, "4.5.1" },
{ 378758, "4.5.1" },
{ 379893, "4.5.2" },
{ 381029, "4.6 Preview" },
{ 393273, "4.6 RC1" },
{ 393292, "4.6 RC2" },
{ 393295, "4.6" },
{ 393297, "4.6" },
{ 394254, "4.6.1" },
{ 394271, "4.6.1" },
{ 394747, "4.6.2 Preview" },
{ 394748, "4.6.2 Preview" },
{ 394757, "4.6.2 Preview" },
{ 394802, "4.6.2" },
{ 394806, "4.6.2" },
Why not try IIF function (requires SQL Server 2012 and later)
IIF(a>b, a, b)
That's it.
(Hint: be careful about either would be null
, since the result of a>b
will be false whenever either is null. So b
will be the result in this case)
Error 0x80040154 is COM's REGDB_E_CLASSNOTREG, which means "Class not registered". Basically, a COM class is not declared in the installation registry.
If you get this error when trying to register a DLL, it may be possible that the registration code for this DLL is trying to instantiate another COM server (DLL or EXE) which is missing or not registered on this installation.
If you don't have access to the original DLL source, I would suggest to use SysInternal's Process Monitor tool to track COM registry lookups (there use to be a more simple RegMon tool but it may not work any more).
You should put a filter on the working process (here: Regsvr32.exe) to only capture what's interesting. Then you should look for queries on HKEY_CLASSES_ROOT\[a progid, a string] that fail (with the NAME_NOT_FOUND error for example), or queries on HKEY_CLASSES_ROOT\CLSID\[a guid] that fail.
PS: Unfortunately, there may be many thing that seem to fail on a perfectly working Windows system, so you'll have to study all errors carefully. Good luck :-)
Generally don't use any of these answers, they often won't scale (there's exceptions here and there, sure)
These approaches are incompatible with how GCD is intended to work and will end up either causing deadlocks and/or killing the battery by nonstop polling.
In other words, rearrange your code so that there is no synchronous waiting for a result, but instead deal with a result being notified of change of state (eg callbacks/delegate protocols, being available, going away, errors, etc.). (These can be refactored into blocks if you don't like callback hell.) Because this is how to expose real behavior to the rest of the app than hide it behind a false façade.
Instead, use NSNotificationCenter, define a custom delegate protocol with callbacks for your class. And if you don't like mucking with delegate callbacks all over, wrap them into a concrete proxy class that implements the custom protocol and saves the various block in properties. Probably also provide convenience constructors as well.
The initial work is slightly more but it will reduce the number of awful race-conditions and battery-murdering polling in the long-run.
(Don't ask for an example, because it's trivial and we had to invest the time to learn objective-c basics too.)

It's very simple. Git doesn't care about what's the name of its directory. It only cares what's inside. So you can simply do:
# copy the directory into newrepo dir that exists already (else create it)
$ cp -r gitrepo1 newrepo
# remove .git from old repo to delete all history and anything git from it
$ rm -rf gitrepo1/.git
Note that the copy is quite expensive if the repository is large and with a long history. You can avoid it easily too:
# move the directory instead
$ mv gitrepo1 newrepo
# make a copy of the latest version
# Either:
$ mkdir gitrepo1; cp -r newrepo/* gitrepo1/ # doesn't copy .gitignore (and other hidden files)
# Or:
$ git clone --depth 1 newrepo gitrepo1; rm -rf gitrepo1/.git
# Or (look further here: http://stackoverflow.com/q/1209999/912144)

Once you create newrepo
, the destination to put gitrepo1
could be anywhere, even inside newrepo
if you want it. It doesn't change the procedure, just the path you are writing gitrepo1
back.
This can now be done as of docker-compose v2+ as part of the build
object;
docker-compose.yml
version: '2'
services:
my_image_name:
build:
context: . #current dir as build context
args:
var1: 1
var2: c
In the above example "var1" and "var2" will be sent to the build environment.
Note: any env variables (specified by using the environment
block) which have the same name as args
variable(s) will override that variable.
I just wanted to add :--
Popping out from backstack using following
fragmentManager.popBackStack()
is just about removing the fragments from the transaction, no way it is going to remove the fragment from the screen. So ideally, it may not be visible to you but there may be two or three fragments stacked over each other, and on back key press the UI may look cluttered,stacked.
Just taking a simple example:-
Suppose you have a fragmentA which loads Fragmnet B using fragmentmanager.replace() and then we do addToBackStack, to save this transaction. So the flow is :--
STEP 1 -> FragmentA->FragmentB (we moved to FragmentB, but Fragment A is in background, not visible).
Now You do some work in fragmentB and press the Save button—which after saving should go back to fragmentA.
STEP 2-> On save of FragmentB, we go back to FragmentA.
STEP 3 ->So common mistake would be... in Fragment B,we will do fragment Manager.replace() fragmentB with fragmentA.
But what actually is happenening, we are loading Fragment A again, replacing FragmentB . So now there are two FragmentA (one from STEP-1, and one from this STEP-3).
Two instances of FragmentsA are stacked over each other, which may not be visible , but it is there.
So even if we do clear the backstack by above methods, the transaction is cleared but not the actual fragments. So ideally in such a particular case, on press of save button you simply need to go back to fragmentA by simply doing fm.popBackStack() or fm.popBackImmediate().
So correct Step3-> fm.popBackStack() go back to fragmentA, which is already in memory.
You can do this:
a = np.array([])
for x in y:
a = np.append(a, x)
I would suggest you to use a simple and easy plugin called as Quokka which is very popular these days and helps you debug your code on the go. Quokka.js. One biggest advantage in using this plugin is that you save a lot of time to go on web browser and evaluate your code, with help of this you can see everything happening in VS code, which saves a lot of time.
Some of the other answers are useless because as soon as you re-import the IntelliJ IDEA project from the maven project, all changes will be lost.
The building of the jar needs to be triggered by a run/debug configuration, not by the project settings.
Jetbrains has a nice description of how you can accomplish this here:
https://www.jetbrains.com/help/idea/maven.html
Scroll down to the section called "Configuring triggers for Maven goals".
(The only disadvantage of their description is that their screenshots are in the default black-on-white color scheme instead of the super-awesome darcula theme. Ugh!)
So, basically, what you do is that you open the "Maven Projects" panel, you find the project of interest, (in your case, the project that builds your jar,) underneath it you find the maven goal that you want to execute, (usually the "package" goal creates jars,) you open up the context menu on it, (right-click on a Windows machine,) and there will be an "Execute before Run/Debug..." option that you can select and it will take you by the hand from there. Really easy.
You can also use the carriage return:
sys.stdout.write("Download progress: %d%% \r" % (progress) )
sys.stdout.flush()
Using jQuery button click
$('#button_id').on('click',function(){
$('#form_id').submit();
});
The following answer is not exactly optimal by any measure, but I needed something that maintains its position within the container whilst it stretches the inner div fully.
https://jsfiddle.net/fah5axm5/
$(function() {
$(window).on('load resize', ppaFullWidth);
function ppaFullWidth() {
var $elements = $('[data-ppa-full-width="true"]');
$.each( $elements, function( key, item ) {
var $el = $(this);
var $container = $el.closest('.container');
var margin = parseInt($container.css('margin-left'), 10);
var padding = parseInt($container.css('padding-left'), 10)
var offset = margin + padding;
$el.css({
position: "relative",
left: -offset,
"box-sizing": "border-box",
width: $(window).width(),
"padding-left": offset + "px",
"padding-right": offset + "px"
});
});
}
});
I expand on spectra‘s answer so people don’t have to try it for themselves.
This was done on Oracle Database 11g Express Edition Release 11.2.0.2.0 - Production.
CREATE TABLE CUSTOMERS

Since iOS 6, UIKit supports drawing attributed strings, so no extension or replacement is needed.
From UILabel
:
@property(nonatomic, copy) NSAttributedString *attributedText;
You just need to build up your NSAttributedString
. There are basically two ways:
Append chunks of text with the same attributes - for each part create one NSAttributedString
instance and append them to one NSMutableAttributedString
Create attributed text from plain string and then add attributed for given ranges – find the range of your number (or whatever) and apply different color attribute on that.
In one of my machine, delimiting the word with "\b
" (without the quotes) did not work. The solution was to use "\<
" for starting delimiter and "\>
" for ending delimiter.
To explain with Joakim Lundberg's example:
$ echo "bar embarassment" | sed "s/\<bar\>/no bar/g"
no bar embarassment
You can use this for getting current and log times:
#!/bin/bash
log="log_file_name"
while read line
do
current_hours=`date | awk 'BEGIN{FS="[ :]+"}; {print $4}'`
current_minutes=`date | awk 'BEGIN{FS="[ :]+"}; {print $5}'`
current_seconds=`date | awk 'BEGIN{FS="[ :]+"}; {print $6}'`
log_file_hours=`echo $line | awk 'BEGIN{FS="[ [/:]+"}; {print $7}'`
log_file_minutes=`echo $line | awk 'BEGIN{FS="[ [/:]+"}; {print $8}'`
log_file_seconds=`echo $line | awk 'BEGIN{FS="[ [/:]+"}; {print $9}'`
done < $log
And compare log_file_*
and current_*
variables.
The word check_
in the name means that if the command (the shell in this case that returns the exit status of the last command (yum
in this case)) returns non-zero status then it raises CalledProcessError
exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_
methods. You could use subprocess.call
in your case because you are ignoring the captured output, e.g.:
import subprocess
rc = subprocess.call(['grep', 'pattern', 'file'],
stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
...
elif rc == 1: # not found
...
elif rc > 1: # error
...
You don't need shell=True
to run the commands from your question.
Path.GetDirectoryName(Application.ExecutablePath)
eg. value:
C:\Projects\ConsoleApplication1\bin\Debug
There's a native and less intrusive alternative, which works only for your call.
URL url = new URL(“location address”);
URLConnection uc = url.openConnection();
String userpass = username + ":" + password;
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userpass.getBytes()));
uc.setRequestProperty ("Authorization", basicAuth);
InputStream in = uc.getInputStream();
It should probably be noted that the for
loop is faster than the foreach
. So for the original post, if you are worried about performance on a critical component like a renderer, use a for
loop.
Reference: In .NET, which loop runs faster, 'for' or 'foreach'?
I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.
I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:
$('.start').keyup(function() {
var otherInputs = $(this).parents('td').siblings().find('input');
for(var i = 0; i < otherInputs.length; i++) {
alert($(otherInputs[i]).val());
}
return false;
});
I forgot to comment out a line with a MsgBox before executing my macro. Meaning I'd have to click OK over a hundred thousand times. The ESC key was just escaping the message box but not stopping the execution of the macro. Holding the ESC key continuously for a few seconds helped me stop the execution of the code.
Try this. Note there's no database specified - it just runs "on the server"
psql -U postgres -c "drop database databasename"
If that doesn't work, I have seen a problem with postgres holding onto orphaned prepared statements.
To clean them up, do this:
SELECT * FROM pg_prepared_xacts;
then for every id you see, run this:
ROLLBACK PREPARED '<id>';
#include <typeinfo>
...
string s = typeid(YourClass).name()
I use this to check for first launch:
- (NSInteger) checkForFirstLaunch
{
NSInteger result = 0; //no first launch
// Get current version ("Bundle Version") from the default Info.plist file
NSString *currentVersion = (NSString*)[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];
NSArray *prevStartupVersions = [[NSUserDefaults standardUserDefaults] arrayForKey:@"prevStartupVersions"];
if (prevStartupVersions == nil)
{
// Starting up for first time with NO pre-existing installs (e.g., fresh
// install of some version)
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:currentVersion] forKey:@"prevStartupVersions"];
result = 1; //first launch of the app
} else {
if (![prevStartupVersions containsObject:currentVersion])
{
// Starting up for first time with this version of the app. This
// means a different version of the app was alread installed once
// and started.
NSMutableArray *updatedPrevStartVersions = [NSMutableArray arrayWithArray:prevStartupVersions];
[updatedPrevStartVersions addObject:currentVersion];
[[NSUserDefaults standardUserDefaults] setObject:updatedPrevStartVersions forKey:@"prevStartupVersions"];
result = 2; //first launch of this version of the app
}
}
// Save changes to disk
[[NSUserDefaults standardUserDefaults] synchronize];
return result;
}
(if the user deletes the app and re-installs it, it counts like a first launch)
In the AppDelegate I check for first launch and create a navigation-controller with the login screens (login and register), which I put on top of the current main window:
[self.window makeKeyAndVisible];
if (firstLaunch == 1) {
UINavigationController *_login = [[UINavigationController alloc] initWithRootViewController:loginController];
[self.window.rootViewController presentViewController:_login animated:NO completion:nil];
}
As this is on top of the regular view controller it's independent from the rest of your app and you can just dismiss the view controller, if you don't need it anymore. And you can also present the view this way, if the user presses a button manually.
BTW: I save the login-data from my users like this:
KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:@"com.youridentifier" accessGroup:nil];
[keychainItem setObject:password forKey:(__bridge id)(kSecValueData)];
[keychainItem setObject:email forKey:(__bridge id)(kSecAttrAccount)];
For the logout: I switched away from CoreData (too slow) and use NSArrays and NSDictionaries to manage my data now. Logout just means to empty those arrays and dictionaries. Plus I make sure to set my data in viewWillAppear.
That's it.
Swift Solution
Follow these steps:
Set the height constraint for the table from the storyboard.
Drag the height constraint from the storyboard and create @IBOutlet
for it in the view controller file.
@IBOutlet var tableHeight: NSLayoutConstraint!
Then you can change the height for the table dynamicaly using this code:
override func viewWillLayoutSubviews() {
super.updateViewConstraints()
self.tableHeight?.constant = self.table.contentSize.height
}
If the last row is cut off, try to call viewWillLayoutSubviews()
in willDisplay cell
function:
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
self.viewWillLayoutSubviews()
}
I also had this issue and ended up using Andy's code to create a function to clean things up when multiple commands need to be run.
It'll return stderr, stdout, and exit codes as objects. One thing to note: the function won't accept .\
in the path; full paths must be used.
Function Execute-Command ($commandTitle, $commandPath, $commandArguments)
{
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = $commandPath
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = $commandArguments
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$p.WaitForExit()
[pscustomobject]@{
commandTitle = $commandTitle
stdout = $p.StandardOutput.ReadToEnd()
stderr = $p.StandardError.ReadToEnd()
ExitCode = $p.ExitCode
}
}
Here's how to use it:
$DisableACMonitorTimeOut = Execute-Command -commandTitle "Disable Monitor Timeout" -commandPath "C:\Windows\System32\powercfg.exe" -commandArguments " -x monitor-timeout-ac 0"
As the question and user3490026's answer are a top search hit, I have made a reproducible example and a brief illustration of the suggestions made so far, together with a solution that explicitly addresses the OP's question.
One of the things that ggplot2
does and which can be confusing is that it automatically blends certain legends when they are associated with the same variable. For instance, factor(gear)
appears twice, once for linetype
and once for fill
, resulting in a combined legend. By contrast, gear
has its own legend entry as it is not treated as the same as factor(gear)
. The solutions offered so far usually work well. But occasionally, you may need to override the guides. See my last example at the bottom.
# reproducible example:
library(ggplot2)
p <- ggplot(data = mtcars, aes(x = mpg, y = disp, group = gear)) +
geom_point(aes(color = vs)) +
geom_point(aes(shape = factor(cyl))) +
geom_line(aes(linetype = factor(gear))) +
geom_smooth(aes(fill = factor(gear), color = gear)) +
theme_bw()
Remove all legends: @user3490026
p + theme(legend.position = "none")
Remove all legends: @duhaime
p + guides(fill = FALSE, color = FALSE, linetype = FALSE, shape = FALSE)
Turn off legends: @Tjebo
ggplot(data = mtcars, aes(x = mpg, y = disp, group = gear)) +
geom_point(aes(color = vs), show.legend = FALSE) +
geom_point(aes(shape = factor(cyl)), show.legend = FALSE) +
geom_line(aes(linetype = factor(gear)), show.legend = FALSE) +
geom_smooth(aes(fill = factor(gear), color = gear), show.legend = FALSE) +
theme_bw()
Remove fill so that linetype becomes visible
p + guides(fill = FALSE)
Same as above via the scale_fill_ function:
p + scale_fill_discrete(guide = FALSE)
And now one possible answer to the OP's request
"to keep the legend of one layer (smooth) and remove the legend of the other (point)"
Turn some on some off ad-hoc post-hoc
p + guides(fill = guide_legend(override.aes = list(color = NA)),
color = FALSE,
shape = FALSE)
Changing the casing to all lowercases worked for me.
I think you summed it up quite well in your own answer.
In the process of UTF-8-ing(?) from end to end you might also want to make sure java itself is using UTF-8. Use -Dfile.encoding=utf-8 as parameter to the JVM (can be configured in catalina.bat).
You would just do the same thing, looping through the array to search for the term you want. Of course if it's a sorted array this would be much faster, so something similar to prehaps:
for(int i = 0; i < arraySize; i++){
if(array[i] == itemToFind){
break;
}
}
You can log all uncaught exceptions on the main thread by assigning a handler to sys.excepthook
, perhaps using the exc_info
parameter of Python's logging functions:
import sys
import logging
logging.basicConfig(filename='/tmp/foobar.log')
def exception_hook(exc_type, exc_value, exc_traceback):
logging.error(
"Uncaught exception",
exc_info=(exc_type, exc_value, exc_traceback)
)
sys.excepthook = exception_hook
raise Exception('Boom')
If your program uses threads, however, then note that threads created using threading.Thread
will not trigger sys.excepthook
when an uncaught exception occurs inside them, as noted in Issue 1230540 on Python's issue tracker. Some hacks have been suggested there to work around this limitation, like monkey-patching Thread.__init__
to overwrite self.run
with an alternative run
method that wraps the original in a try
block and calls sys.excepthook
from inside the except
block. Alternatively, you could just manually wrap the entry point for each of your threads in try
/except
yourself.

Open the file with open(filename, 'rb')
and:
def tail(f, window=20):
"""Returns the last `window` lines of file `f` as a list.

if window == 0:
return []
BUFSIZ = 1024
f.seek(0, 2)
remaining_bytes = f.tell()
size = window + 1
block = -1
data = []
while size > 0 and remaining_bytes > 0:
if remaining_bytes - BUFSIZ > 0:
# Seek back one whole BUFSIZ
f.seek(block * BUFSIZ, 2)
# read BUFFER
bunch = f.read(BUFSIZ)
else:
# file too small, start from beginning
f.seek(0, 0)
# only read what was not read
bunch = f.read(remaining_bytes)
bunch = bunch.decode('utf-8')
data.insert(0, bunch)
size -= bunch.count('\n')
remaining_bytes -= BUFSIZ
block -= 1
return ''.join(data).splitlines()[-window:]
This is working for me:
$user_info = DB::table('usermetas')
->select('browser', DB::raw('count(*) as total'))
->groupBy('browser')
->get();
function extract_ids($cats){
$res = array();
foreach($cats as $k=>$v) {
$res[]= $v->id;
}
return $res
}
and use it in one line:
$ids = extract_ids($cats);
You can use Sys.time()
. However, when you record the time difference in a table or a csv file, you cannot simply say end - start
. Instead, you should define the unit:
f_name <- function (args*){
start <- Sys.time()
""" You codes here """
end <- Sys.time()
total_time <- as.numeric (end - start, units = "mins") # or secs ...
}
Then you can use total_time
which has a proper format.

String class is FINAL
it mean you can't create any class to inherit it and change the basic structure and make the Sting mutable.
Another thing instance variable and methods of String class that are provided are such that you can't change String
object once created.
The reason what you have added doesn't make the String immutable at all.This all says how the String is stored in heap.Also string pool make the huge difference in performance
The problem is that you made a Tiny mistake!
This is the JS code I use:
var jobName = document.getElementById("txtJob").value;
You should not use name="". instead use id="".
Even if you've configured Apache to listen on another port, you will still get this error if another program is using the default SSL port 443.
What you also need to edit is the http-ssl.conf file and alter the line Listen 443 and change the port number there.
Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.

M.K. offered a great plugin in his answer. Plugin can be found here. However, for the sake of completion, I thought it'd be a good idea to put it together in one answer for AngularJS.
Start by injecting the bower or npm (whichever is preferred)
bower install jquery-scrollLock --save
npm install jquery-scroll-lock --save
Add the following directive. I am choosing to add it as an attribute
(function() {
'use strict';
angular
.module('app')
.directive('isolateScrolling', isolateScrolling);
function isolateScrolling() {
return {
restrict: 'A',
link: function(sc, elem, attrs) {
$('.scroll-container').scrollLock();
}
}
}
})();
And the important piece the plugin fails to document in their website is the HTML structure that it must follow.
<div class="scroll-container locked">
<div class="scrollable" isolate-scrolling>
... whatever ...
</div>
</div>
The attribute isolate-scrolling
must contain the scrollable
class and it all needs to be inside the scroll-container
class or whatever class you choose and the locked
class must be cascaded.

Edit: Added sample code for Python 3
Note: this other answer looks like it provides a much more complete implementation similar to the following (with more features).
First, make a metaclass:
class MetaConst(type):
def __getattr__(cls, key):
return cls[key]
def __setattr__(cls, key, value):
raise TypeError
This prevents statics properties from being changed. Then make another class that uses that metaclass:
class Const(object):
__metaclass__ = MetaConst
def __getattr__(self, name):
return self[name]
def __setattr__(self, name, value):
raise TypeError
Or, if you're using Python 3:
class Const(object, metaclass=MetaConst):
def __getattr__(self, name):
return self[name]
def __setattr__(self, name, value):
raise TypeError
This should prevent instance props from being changed. To use it, inherit:
class MyConst(Const):
A = 1
B = 2
Now the props, accessed directly or via an instance, should be constant:
MyConst.A
# 1
my_const = MyConst()
my_const.A
# 1

The answer was simply moving the PLSQL Developer folder from the "Program Files (x86) into the "Program Files" folder - weird!
You can use str.split
by whitespace (default separator) and parameter expand=True
for DataFrame
with assign to new columns:
df = pd.DataFrame({'row': ['00000 UNITED STATES', '01000 ALABAMA',
'01001 Autauga County, AL', '01003 Baldwin County, AL',
'01005 Barbour County, AL']})
print (df)
row
0 00000 UNITED STATES
1 01000 ALABAMA
2 01001 Autauga County, AL
3 01003 Baldwin County, AL
4 01005 Barbour County, AL
df[['a','b']] = df['row'].str.split(n=1, expand=True)
print (df)
row a b
0 00000 UNITED STATES 00000 UNITED STATES
1 01000 ALABAMA 01000 ALABAMA
2 01001 Autauga County, AL 01001 Autauga County, AL
3 01003 Baldwin County, AL 01003 Baldwin County, AL
4 01005 Barbour County, AL 01005 Barbour County, AL
Modification if need remove original column with DataFrame.pop
df[['a','b']] = df.pop('row').str.split(n=1, expand=True)
print (df)
a b
0 00000 UNITED STATES
1 01000 ALABAMA
2 01001 Autauga County, AL
3 01003 Baldwin County, AL
4 01005 Barbour County, AL
What is same like:
df[['a','b']] = df['row'].str.split(n=1, expand=True)
df = df.drop('row', axis=1)
print (df)
a b
0 00000 UNITED STATES
1 01000 ALABAMA
2 01001 Autauga County, AL
3 01003 Baldwin County, AL
4 01005 Barbour County, AL
If get error:
#remove n=1 for split by all whitespaces
df[['a','b']] = df['row'].str.split(expand=True)
ValueError: Columns must be same length as key
You can check and it return 4 column DataFrame
, not only 2:
print (df['row'].str.split(expand=True))
0 1 2 3
0 00000 UNITED STATES None
1 01000 ALABAMA None None
2 01001 Autauga County, AL
3 01003 Baldwin County, AL
4 01005 Barbour County, AL
Then solution is append new DataFrame
by join
:
df = pd.DataFrame({'row': ['00000 UNITED STATES', '01000 ALABAMA',
'01001 Autauga County, AL', '01003 Baldwin County, AL',
'01005 Barbour County, AL'],
'a':range(5)})
print (df)
a row
0 0 00000 UNITED STATES
1 1 01000 ALABAMA
2 2 01001 Autauga County, AL
3 3 01003 Baldwin County, AL
4 4 01005 Barbour County, AL
df = df.join(df['row'].str.split(expand=True))
print (df)
a row 0 1 2 3
0 0 00000 UNITED STATES 00000 UNITED STATES None
1 1 01000 ALABAMA 01000 ALABAMA None None
2 2 01001 Autauga County, AL 01001 Autauga County, AL
3 3 01003 Baldwin County, AL 01003 Baldwin County, AL
4 4 01005 Barbour County, AL 01005 Barbour County, AL
With remove original column (if there are also another columns):
df = df.join(df.pop('row').str.split(expand=True))
print (df)
a 0 1 2 3
0 0 00000 UNITED STATES None
1 1 01000 ALABAMA None None
2 2 01001 Autauga County, AL
3 3 01003 Baldwin County, AL
4 4 01005 Barbour County, AL
You can't.
ANYTHING that can be read by the browser can also be read by humans. If you want something hidden, don't send it to the user's browser.
You can add all sorts of gimmicks and tricks to disable right-click and disable ctrl+U
All a user has to do is add view-source:

Daniel LeCheminant's code didn't work for me after converting it from CoffeeScript to JavaScript (js2coffee). It kept bombing out on the _.defer()
line.
I assumed this was something to do with jQuery deferreds, so I changed it to $.Deferred()
and it's working now. I tested it in Internet Explorer 11, Firefox 35, and Chrome 39 with jQuery 2.1.1. The usage is the same as described in Daniel's post.
var TrelloClipboard;
TrelloClipboard = new ((function () {
function _Class() {
this.value = "";
$(document).keydown((function (_this) {
return function (e) {
var _ref, _ref1;

return;
}
if ($(e.target).is("input:visible,textarea:visible")) {
return;
}
if (typeof window.getSelection === "function" ? (_ref = window.getSelection()) != null ? _ref.toString() : void 0 : void 0) {
return;
}
if ((_ref1 = document.selection) != null ? _ref1.createRange().text : void 0) {
return;
}
return $.Deferred(function () {
var $clipboardContainer;
$clipboardContainer = $("#clipboard-container");
$clipboardContainer.empty().show();
return $("<textarea id='clipboard'></textarea>").val(_this.value).appendTo($clipboardContainer).focus().select();
});
};
})(this));
$(document).keyup(function (e) {

return $("#clipboard-container").empty().hide();
}
});
}
_Class.prototype.set = function (value) {
this.value = value;
};
return _Class;
})());
I think you want to specify
-H "Content-Type:text/xml"
with a colon, not an equals.
To make it more interesting and to hopefully enable less hair pulling for someone else. Using python, built dictionary for a device which we can use curl to configure.
Problem: {"timezone":"+5"} //throws an error " 5"
Solution: {"timezone":"%2B"+"5"} //Works
So, in a nutshell:
var = {"timezone":"%2B"+"5"}
json = JSONEncoder().encode(var)
subprocess.call(["curl",ipaddress,"-XPUT","-d","data="+json])
Thanks to this post!
We get around this problem by deploying a main jar file myapp.jar
which contains a manifest (Manifest.mf
) file specifying a classpath with the other required jars, which are then deployed alongside it. In this case, you only need to declare java -jar myapp.jar
when running the code.
So if you deploy the main jar
into some directory, and then put the dependent jars into a lib
folder beneath that, the manifest looks like:
Manifest-Version: 1.0
Implementation-Title: myapp
Implementation-Version: 1.0.1
Class-Path: lib/dep1.jar lib/dep2.jar
NB: this is platform-independent - we can use the same jars to launch on a UNIX server or on a Windows PC.
There are many answers here but I will put here the most important one which everyone should use.
1. Column
Column(
children: <Widget>[
Text('Widget A'), //Can be any widget
SizedBox(height: 20,), //height is space betweeen your top and bottom widget
Text('Widget B'), //Can be any widget
],
),
2. Wrap
Wrap(
direction: Axis.vertical, // We have to declare Axis.vertical, otherwise by default widget are drawn in horizontal order
spacing: 20, // Add spacing one time which is same for all other widgets in the children list
children: <Widget>[
Text('Widget A'), // Can be any widget
Text('Widget B'), // Can be any widget
]
)
<div class="tabbable">
<ul class="nav nav-tabs">
<li class="active"><a href="#aaa" data-toggle="tab">AAA</a></li>
<li><a href="#bbb" data-toggle="tab">BBB</a></li>
<li><a href="#ccc" data-toggle="tab">CCC</a></li>
</ul>
<div class="tab-content" id="tabs">
<div class="tab-pane fade active in" id="aaa">...Content...</div>
<div class="tab-pane" id="bbb">...Content...</div>
<div class="tab-pane" id="ccc">...Content...</div>
</div>
</div>
Add active class to any li element you want to be active after page load. And also adding active class to content div is needed ,fade in classes are useful for a smooth transition.
Some operations are quicker than java heap space manager. Delaying operations for some time can free memory space. You can use this method to escape heap size error:
waitForGarbageCollector(new Runnable() {
@Override
public void run() {
// Your operations.
}
});
/**
* Measure used memory and give garbage collector time to free up some
* of the space.
*
* @param callback Callback operations to be done when memory is free.
*/
public static void waitForGarbageCollector(final Runnable callback) {
Runtime runtime;
long maxMemory;
long usedMemory;
double availableMemoryPercentage = 1.0;
final double MIN_AVAILABLE_MEMORY_PERCENTAGE = 0.1;
final int DELAY_TIME = 5 * 1000;
runtime =
Runtime.getRuntime();
maxMemory =
runtime.maxMemory();
usedMemory =
runtime.totalMemory() -
runtime.freeMemory();
availableMemoryPercentage =
1 -
(double) usedMemory /
maxMemory;
if (availableMemoryPercentage < MIN_AVAILABLE_MEMORY_PERCENTAGE) {
try {
Thread.sleep(DELAY_TIME);
} catch (InterruptedException e) {
e.printStackTrace();
}
waitForGarbageCollector(
callback);
} else {
// Memory resources are available, go to next operation:
callback.run();
}
}
Pass in a regexp as the parameter:
js> "Hello awesome, world!".split(/[\s,]+/)
Hello,awesome,world!
Edited to add:
You can get the last element by selecting the length of the array minus 1:
>>> bits = "Hello awesome, world!".split(/[\s,]+/)
["Hello", "awesome", "world!"]
>>> bit = bits[bits.length - 1]
"world!"
... and if the pattern doesn't match:
>>> bits = "Hello awesome, world!".split(/foo/)
["Hello awesome, world!"]
>>> bits[bits.length - 1]
"Hello awesome, world!"
If your merge and the corresponding commits were not pushed yet, you can always switch to another branch, delete the original one and re-create it.
For example, I accidentally merged a develop branch into master and wanted to undo that. Using the following steps:
git checkout develop
git branch -D master
git branch -t master origin/master
Voila! Master is at the same stage as origin, and your mis-merged state is erased.
For me the only thing that worked 100% when spring security is used was to skip all the additional fluff of extra filters and beans and whatever indirect "magic" people kept suggesting that worked for them but not for me.
Instead just force it to write the headers you need with a plain StaticHeadersWriter
:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
// your security config here
.authorizeRequests()
.antMatchers(HttpMethod.TRACE, "/**").denyAll()
.antMatchers("/admin/**").authenticated()
.anyRequest().permitAll()
.and().httpBasic()
.and().headers().frameOptions().disable()
.and().csrf().disable()
.headers()
// the headers you want here. This solved all my CORS problems!
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Origin", "*"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Methods", "POST, GET"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Max-Age", "3600"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Credentials", "true"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Headers", "Origin,Accept,X-Requested-With,Content-Type,Access-Control-Request-Method,Access-Control-Request-Headers,Authorization"));
}
}
This is the most direct and explicit way I found to do it. Hope it helps someone.
UPDATE: The really awesome code posted by Gabe Sechan no longer works unless you explicitly request the user to grant the necessary permissions. Here is some code that you can place in your main activity to request these permissions:
if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
!= PackageManager.PERMISSION_GRANTED) {
// Permission has not been granted, therefore prompt the user to grant permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS},
MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
}
ALSO: As someone mentioned in a comment below Gabe's post, you have to add a little snippet of code, android:enabled="true
, to the receiver in order to detect incoming calls when the app is not currently running in the foreground:
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
Want zero warnings? Use it like this:
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));
Explanation: The default value of the extended
option has been deprecated, meaning you need to explicitly pass true or false value.
Try this:
public static void main(String[] args)
{
Pattern p = Pattern.compile("^\\d+$");
Scanner kb = new Scanner(System.in);
int num1;
int num2 = 0;
String temp;
Matcher numberMatcher;
System.out.print("Enter number 1: ");
try
{
num1 = kb.nextInt();
}
catch (java.util.InputMismatchException e)
{
System.out.println("Invalid Input");
//
return;
}
while(num2<num1)
{
System.out.print("Enter number 2: ");
temp = kb.next();
numberMatcher = p.matcher(temp);
if (numberMatcher.matches())
{
num2 = Integer.parseInt(temp);
}
else
{
System.out.println("Invalid Number");
}
}
}
You could try to parse the string into an int
as well, but usually people try to avoid throwing exceptions.
What I have done is that I have defined a regular expression that defines a number, \d
means a numeric digit. The +
sign means that there has to be one or more numeric digits. The extra \
in front of the \d
is because in java, the \
is a special character, so it has to be escaped.
In addition to labeling a directory as a Python package and defining __all__
, __init__.py
allows you to define any variable at the package level. Doing so is often convenient if a package defines something that will be imported frequently, in an API-like fashion. This pattern promotes adherence to the Pythonic "flat is better than nested" philosophy.
Here is an example from one of my projects, in which I frequently import a sessionmaker
called Session
to interact with my database. I wrote a "database" package with a few modules:
database/
__init__.py
schema.py
insertions.py
queries.py
My __init__.py
contains the following code:
import os
from sqlalchemy.orm import sessionmaker
from sqlalchemy import create_engine
engine = create_engine(os.environ['DATABASE_URL'])
Session = sessionmaker(bind=engine)
Since I define Session
here, I can start a new session using the syntax below. This code would be the same executed from inside or outside of the "database" package directory.
from database import Session
session = Session()
Of course, this is a small convenience -- the alternative would be to define Session
in a new file like "create_session.py" in my database package, and start new sessions using:
from database.create_session import Session
session = Session()
There is a pretty interesting reddit thread covering appropriate uses of __init__.py
here:
http://www.reddit.com/r/Python/comments/1bbbwk/whats_your_opinion_on_what_to_include_in_init_py/
The majority opinion seems to be that __init__.py
files should be very thin to avoid violating the "explicit is better than implicit" philosophy.
if you care for the whole page. you can use this:
document.body.getBoundingClientRect().top
_x000D_
If the structures are of compatible types, yes, you can, with something like:
memcpy (dest_struct, source_struct, sizeof (*dest_struct));
The only thing you need to be aware of is that this is a shallow copy. In other words, if you have a char *
pointing to a specific string, both structures will point to the same string.
And changing the contents of one of those string fields (the data that the char *
points to, not the char *
itself) will change the other as well.
If you want a easy copy without having to manually do each field but with the added bonus of non-shallow string copies, use strdup
:
memcpy (dest_struct, source_struct, sizeof (*dest_struct));
dest_struct->strptr = strdup (source_struct->strptr);
This will copy the entire contents of the structure, then deep-copy the string, effectively giving a separate string to each structure.
And, if your C implementation doesn't have a strdup
(it's not part of the ISO standard), get one from here.
A simple solution using fscanf
:
void read_ints (const char* file_name)
{
FILE* file = fopen (file_name, "r");
int i = 0;
fscanf (file, "%d", &i);
while (!feof (file))
{
printf ("%d ", i);
fscanf (file, "%d", &i);
}
fclose (file);
}
Try -
var monthNames = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
var newDate = new Date(form.startDate.value);
var formattedDate = monthNames[newDate.getMonth()] + ' ' + newDate.getFullYear();
I have encounter the same issue and found that i have forgot to prefix the commit message with project identifier. Project identifier is must in our case followed by the commit message. So at the server end it doesn't found the prefix and raised the issue.
well, this using lodash or vanilla javascript it depends on the situation.
but for just return the array that contains the duplicates it can be achieved by the following, offcourse it was taken from @1983
var result = result1.filter(function (o1) {
return result2.some(function (o2) {
return o1.id === o2.id; // return the ones with equal id
});
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));
Try This
if (($val >= 1 && $val <= 10) || ($val >= 20 && $val <= 40))
This will return the value between 1 to 10 & 20 to 40.
You could do
alert(document.getElementById('table1').rows[0].cells.length)
fiddle here http://jsfiddle.net/TEZ73/
alter table table_name rename column oldColumn to newColumn;
One thing that you need to be aware of when reflecting on private members is that if your application is running in medium trust (as, for instance, when you are running on a shared hosting environment), it won't find them -- the BindingFlags.NonPublic option will simply be ignored.
Your return data
approach is correct, that's an example of promise chaining. If you return a promise from your .then()
callback, JavaScript will resolve that promise and pass the data to the next then()
callback.
Just be careful and make sure you handle errors with .catch()
. Promise.all()
rejects as soon as one of the promises in the array rejects.
Quite a few applications seem to implement Steganography on JPEG, so it's feasible:
http://www.jjtc.com/Steganography/toolmatrix.htm
Here's an article regarding a relevant algorithm (PM1) to get you started:
http://link.springer.com/article/10.1007%2Fs00500-008-0327-7#page-1
I figured an easy way to do this was to use a BitSet
.
public static int find(int[] arr) {
BitSet b = new BitSet();
for (int i : arr) {
if (i > 0) {
b.set(i);
}
}
return b.nextClearBit(1);
}
Subtyping is invariant for parameterized types. Even tough the class Dog
is a subtype of Animal
, the parameterized type List<Dog>
is not a subtype of List<Animal>
. In contrast, covariant subtyping is used by arrays, so the array
type Dog[]
is a subtype of Animal[]
.
Invariant subtyping ensures that the type constraints enforced by Java are not violated. Consider the following code given by @Jon Skeet:
List<Dog> dogs = new ArrayList<Dog>(1);
List<Animal> animals = dogs;
animals.add(new Cat()); // compile-time error
Dog dog = dogs.get(0);
As stated by @Jon Skeet, this code is illegal, because otherwise it would violate the type constraints by returning a cat when a dog expected.
It is instructive to compare the above to analogous code for arrays.
Dog[] dogs = new Dog[1];
Object[] animals = dogs;
animals[0] = new Cat(); // run-time error
Dog dog = dogs[0];
The code is legal. However, throws an array store exception. An array carries its type at run-time this way JVM can enforce type safety of covariant subtyping.
To understand this further let's look at the bytecode generated by javap
of the class below:
import java.util.ArrayList;
import java.util.List;
public class Demonstration {
public void normal() {
List normal = new ArrayList(1);
normal.add("lorem ipsum");
}
public void parameterized() {
List<String> parameterized = new ArrayList<>(1);
parameterized.add("lorem ipsum");
}
}
Using the command javap -c Demonstration
, this shows the following Java bytecode:
Compiled from "Demonstration.java"
public class Demonstration {
public Demonstration();
Code:
0: aload_0
1: invokespecial #1 // Method java/lang/Object."<init>":()V
4: return
public void normal();
Code:
0: new #2 // class java/util/ArrayList
3: dup
4: iconst_1
5: invokespecial #3 // Method java/util/ArrayList."<init>":(I)V
8: astore_1
9: aload_1
10: ldc #4 // String lorem ipsum
12: invokeinterface #5, 2 // InterfaceMethod java/util/List.add:(Ljava/lang/Object;)Z
17: pop
18: return
public void parameterized();
Code:
0: new #2 // class java/util/ArrayList
3: dup
4: iconst_1
5: invokespecial #3 // Method java/util/ArrayList."<init>":(I)V
8: astore_1
9: aload_1
10: ldc #4 // String lorem ipsum
12: invokeinterface #5, 2 // InterfaceMethod java/util/List.add:(Ljava/lang/Object;)Z
17: pop
18: return
}
Observe that the translated code of method bodies are identical. Compiler replaced each parameterized type by its erasure. This property is crucial meaning that it did not break backwards compatibility.
In conclusion, run-time safety is not possible for parameterized types, since compiler replaces each parameterized type by its erasure. This makes parameterized types are nothing more than syntactic sugar.
pip install --user package_name
to install a package that should include CLI executables.import package_name
lib/python/...
occurs in the output and replace it all with bin
$HOME/Library/Python/2.7/bin
Because of the new System Integrity Protection in macOS 10.11 El Capitan, you can no longer sudo pip install
. We won't debate the merits of that here.
Another answer explains that you should pip install --user
which is correct. But they sent you to the back alleys to figure out what to do about your $PATH
so that you could get access to installed executables. Luckily, I've already solved a similar need for an unrelated question.
Here is a transcript of how I solved the problem on one of my systems. I'm including it all rather just than the $PATH
that worked for me, because your system may be different from mine. This process should work for everybody.

I was able to change the selected view color like this. I think this is the SIMPLE WAY (because you don't have to create instance of layouts and variables.
MAKE SURE YOU DONT GIVE ANY BACKGROUND COLOR INSIDE YOUR RECYCLER VIEW's TAG.
holder.itemView.setBackgroundColor(Color.parseColor("#8DFFFFFF"));
onBindViewHolder() method is given below
@Override
public void onBindViewHolder(@NonNull final MyViewHolder holder, final int position) {
holder.item_1.setText(list_items.get(position).item_1);
holder.item_2.setText(list_items.get(position).item_2);
holder.select_cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override

}else {
holder.itemView.setBackgroundColor(Color.parseColor("#FFFFFF"));

Just as an FYI, you can also specify those things as column attributes. For instance, I might have done:
.order_by(model.Entry.amount.desc())
This is handy since it avoids an import
, and you can use it on other places such as in a relation definition, etc.

You can also use this

Best answer is to use the from dateutil import parser
.
usage:
from dateutil import parser
datetime_obj = parser.parse('2018-02-06T13:12:18.1278015Z')
print datetime_obj
# output: datetime.datetime(2018, 2, 6, 13, 12, 18, 127801, tzinfo=tzutc())

will open a resource in the same directory as the file executing the command. In other words, if you're just running the file ~/test.php, your script will create ~/myText.txt.
This can get a little confusing if you're using any URL rewriting (such as in an MVC framework) as it will likely create the new file in whatever the directory contains the root index.php file.
Also, you must have correct permissions set and may want to test before writing to the file. The following would help you debug:
$fp = fopen("myText.txt","wb");
if( $fp == false ){
//do debugging or logging here
}else{
fwrite($fp,$content);
fclose($fp);
}
First thing first, button()
is a jQuery ui function to create a button widget which has nothing to do with jQuery core, it just styles the button.
So if you want to use the widget add jQuery ui's javascript and CSS files or alternatively remove it, like this:
$("#filter").click(function(){
alert('clicked!');
});
Another thing that might have caused you the problem is if you didn't wait for the input to be rendered and wrote the code before the input. jQuery has the ready function, or it's alias $(func)
which execute the callback once the DOM is ready.
Usage:
$(function(){
$("#filter").click(function(){
alert('clicked!');
});
});
So even if the order is this it will work:
$(function(){
$("#filter").click(function(){
alert('clicked!');
});
});
<input type="button" id="filter" name="filter" value="Filter" />
As many have said, you can't stop someone from downloading content. You just can't.
But you can make it harder.
You can overlay images with a transparent div
, which will prevent people from right clicking on them (or, setting the background of a div
to the image will have the same effect).
If you're worried about cross-linking (ie, other people linking to your images, you can check the HTTP referrer and redirect requests which come from a domain which isn't yours to "something else".

the solutions, maybe
You should use .Load

"The LoadXml method is for loading an XML string directly. You want to use the Load method instead."

I recently needed to provide a more mobile-friendly, responsive version of a .pdf document, because narrow phone screens required scrolling right and left a lot. To allow just vertical scrolling and avoid horizontal scrolling, the following steps worked for me:
The result looked good and was usable in both desktop and mobile environments.
One of the most interesting features in HTML5
is the ability to store data locally and to allow the application to run offline. There are three different APIs that deal with these features and choosing one depends on what exactly you want to do with the data you're planning to store locally:
For more reference see Introducing the HTML5 storage APIs
And how to use
http://cookbooks.adobe.com/post_Store_data_in_the_HTML5_SQLite_database-19115.html
if you like another alternate approach with up
and down
method try this:
def up
change_table :uploads do |t|
t.references :user, index: true
end
end
def down
change_table :uploads do |t|
t.remove_references :user, index: true
end
end
This post helped me today, but I had to experiment to do what I needed. Here is what I found.
Should you want to add more complex time periods, for example 1 year and 15 days, you can use
UPDATE tablename SET datefieldname = curdate() + INTERVAL 15 DAY + INTERVAL 1 YEAR;
I found that using DATE_ADD
doesn't allow for adding more than one interval. And there is no YEAR_DAYS interval keyword, though there are others that combine time periods. If you are adding times, use now()
rather than curdate()
.
To avoid confusion, paraphrasing both question and answer. I am assuming that user who posted this question wanted to save dictionary type object in JSON file format but when the user used json.dump
, this method dumped all its content in one line. Instead, he wanted to record each dictionary entry on a new line. To achieve this use:
with g as outfile:
json.dump(hostDict, outfile,indent=2)
Using indent = 2
helped me to dump each dictionary entry on a new line. Thank you @agf. Rewriting this answer to avoid confusion.
The error is because difference in datatypes of y_pred and y_true. y_true might be dataframe and y_pred is arraylist. If you convert both to arrays, then issue will get resolved.
According to bitbucket knowledgebase it may also be caused by the owner of the repository being over the plan limit.
If you look further down the page it seems to also be possible to trig this error by using a too old git version (1.7 is needed at the moment).
Another option is to ensure that the full qualified host name (FQDN) is listed in /etc/hosts. This worked for me on Ubuntu v11.10 without having to change the default Apache configuration.
I suggest to use
for string only state values
export default class Home extends React.Component<{}, { [key: string]: string }> { }
for string key and any type of state values
export default class Home extends React.Component<{}, { [key: string]: any}> { }
for any key / any values
export default class Home extends React.Component<{}, { [key: any]: any}> {}
You can do it like this:
In your main view controller:
func showModal() {
let modalViewController = ModalViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
presentViewController(modalViewController, animated: true, completion: nil)
}
In your modal view controller:
class ModalViewController: UIViewController {
override func viewDidLoad() {
view.backgroundColor = UIColor.clearColor()
view.opaque = false
}
}
If you are working with a storyboard:
Just add a Storyboard Segue with Kind
set to Present Modally
to your modal view controller and on this view controller set the following values:
As Crashalot pointed out in his comment: Make sure the segue only uses Default
for both Presentation
and Transition
. Using Current Context
for Presentation
makes the modal turn black instead of remaining transparent.
For infinite scrolling with days it's important you have the good fragment in the pager therefore I wrote my answer on this on page (Viewpager in Android to switch between days endlessly)
It's working very well! Above answers did not work for me as I wanted it to work.
You just need to create a deleter class:
struct BarDeleter {
void operator()(Bar* b) { destroy(b); }
};
and provide it as the template argument of unique_ptr
. You'll still have to initialize the unique_ptr in your constructors:
class Foo {
public:
Foo() : bar(create()), ... { ... }
private:
std::unique_ptr<Bar, BarDeleter> bar;
...
};
As far as I know, all the popular c++ libraries implement this correctly; since BarDeleter
doesn't actually have any state, it does not need to occupy any space in the unique_ptr
.
find . -name "*.java" -print | xargs javac
Kinda brutal, but works like hell. (Use only on small programs, it's absolutely not efficient)
Just add position:absolute; top:0; right:0;
to the CSS for your button.
#button {
line-height: 12px;
width: 18px;
font-size: 8pt;
font-family: tahoma;
margin-top: 1px;
margin-right: 2px;
position:absolute;
top:0;
right:0;
}
I think your problem is that the margin should be specified in the border tag and not in the grid.
With Jquery... You can add class to html elements like this:
$(".divclass").find("p,h1,h2,h3,figure,span,a").addClass('nameclassorid');
nameclassorid no point or # at the beginning
org.json.simple.JSONObject.escape() escapes quotes,\, /, \r, \n, \b, \f, \t and other control characters. It can be used to escape JavaScript codes.
import org.json.simple.JSONObject;
String test = JSONObject.escape("your string");
decimal
is a value type
in .NET. And value types can't be null
. But if you use nullable type
for your decimal
, then you can check your decimal
is null
or not. Like myDecimal?
Nullable types are instances of the System.Nullable struct. A nullable type can represent the normal range of values for its underlying value type, plus an additional null value.
if (myDecimal.HasValue)
But I think in your database, if this column contains nullable values, then it shouldn't be type of decimal
.
The most upvoted answer above is weird in a way that it simply clears the Clipboard and then gets the content (which is then empty). One could clear the clipboard to be sure that some clipboard content type like "formated text" does not "cover" your plain text content you want to save in the clipboard.
The following piece of code replaces all newlines in the clipboard by spaces, then removes all double spaces and finally saves the content back to the clipboard:
import win32clipboard
win32clipboard.OpenClipboard()
c = win32clipboard.GetClipboardData()
win32clipboard.EmptyClipboard()
c = c.replace('\n', ' ')
c = c.replace('\r', ' ')
while c.find(' ') != -1:
c = c.replace(' ', ' ')
win32clipboard.SetClipboardText(c)
win32clipboard.CloseClipboard()
Once I changed Options -Index
to Options +Index
in my conf file, I removed the welcome page and restarted services.

Actually without PDB files and symbolic information they have it would be impossible to create a successful crash report (memory dump files) and Microsoft would not have the complete picture what caused the problem.
And so having PDB improves crash reporting.
The following script removes quotation marks only from around the column value if table is called [Messages] and the column is called [Description].
-- If the content is in the form of "anything" (LIKE '"%"')
-- Then take the whole text without the first and last characters
-- (from the 2nd character and the LEN([Description]) - 2th character)
UPDATE [Messages]
SET [Description] = SUBSTRING([Description], 2, LEN([Description]) - 2)
WHERE [Description] LIKE '"%"'
use this filter:

You need to first transform data1, in your case by calling ToString()
on each element.
List<int> data1 = new List<int> {1,2,3,4,5};
List<string> data2 = new List<string>{"6","3"};
var newData = data1.Select(i => i.ToString()).Intersect(data2);
List<int> data1 = new List<int> {1,2,3,4,5};
List<string> data2 = new List<string>{"6","3"};
var newData = data1.Intersect(data2.Select(s => int.Parse(s));
Note that this will throw an exception if not all strings are numbers. So you could do the following first to check:
int temp;
if(data2.All(s => int.TryParse(s, out temp)))
{
// All data2 strings are int's
}
If you are using Python3.
then you can use Print Function :
your_data = {"Purchase Amount": 'TotalAmount'}
print(your_data, file=open('D:\log.txt', 'w'))
For python2
this is the example of Python Print String To Text File
def my_func():
"""
this function return some value
:return:
"""
return 25.256
def write_file(data):
"""
this function write data to file
:param data:
:return:
"""
file_name = r'D:\log.txt'
with open(file_name, 'w') as x_file:
x_file.write('{} TotalAmount'.format(data))
def run():
data = my_func()
write_file(data)
run()

Currently some people are facing the same issue because of using 12.0.0
version of AdMob lib.
Update it to 12.0.1
. This should fix it. You can read more here
I have been puzzled a lot with this problem, since I am relively new in Python. I cannot apply the solution to the code given by the questioned, since it's not self executable. So I bring a very simple code:
from turtle import *
ts = Screen(); tu = Turtle()
def move(x,y):
print "move()"
tu.goto(100,100)
ts.listen();
ts.onclick(move)
done()
As you can see, the solution consists in using two (dummy) arguments, even if they are not used either by the function itself or in calling it! It sounds crazy, but I believe there must be a reason for it (hidden from the novice!).
I have tried a lot of other ways ('self' included). It's the only one that works (for me, at least).
Another option is to use the Aggregate extension rather than Join:
String s = myDict.Select(x => x.Key + "=" + x.Value).Aggregate((s1, s2) => s1 + ";" + s2);
If you want to change imageview margin but leave all other margins intact.
Get MarginLayoutParameters of your image view in this case: myImageView
MarginLayoutParams marginParams = (MarginLayoutParams) myImageView.getLayoutParams();
Now just change the margin you want to change but leave the others as they are:
marginParams.setMargins(marginParams.leftMargin,
marginParams.topMargin,
150, //notice only changing right margin
marginParams.bottomMargin);
df.ix[10,:]
gives you all the columns from the 10th row. In your case you want everything up to the 10th row which is df.ix[:9,:]
. Note that the right end of the slice range is inclusive: http://pandas.sourceforge.net/gotchas.html#endpoints-are-inclusive
Use +
plus sign (Match one or more of the previous items),
var regexp = /^\S+$/
TrueY's answer seemed the most elegant solution, however, I had to do some messing around because I didn't understand what exactly was going on. Let me clear things up to hopefully save some time for the next person.
TrueY's modified Answer:
::Change the name of notepad.exe to the process .exe that you're trying to track
::Process names are CASE SENSITIVE, so notepad.exe works but Notepad.exe does NOT
::Do not change IMAGENAME
::You can Copy and Paste this into an empty batch file and change the name of
::notepad.exe to the process you'd like to track
::Also, some large programs take a while to no longer show as not running, so
::give this batch a few seconds timer to avoid a false result!!
@echo off
SETLOCAL EnableExtensions
set EXE=notepad.exe
FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto ProcessFound
goto ProcessNotFound
:ProcessFound
echo %EXE% is running
goto END
:ProcessNotFound
echo %EXE% is not running
goto END
:END
echo Finished!
Anyway, I hope that helps. I know sometimes reading batch/command-line can be kind of confusing sometimes if you're kind of a newbie, like me.
In this tutorial is explained how to consume a web api with C#, in this example a console application is used, but you can also use another web api to consume of course.
http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client
You should have a look at the HttpClient
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/yourwebapi");
Make sure your requests ask for the response in JSON using the Accept header like this:
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
Now comes the part that differs from the tutorial, make sure you have the same objects as the other WEB API
, if not, then you have to map the objects to your own objects. ASP.NET
will convert the JSON
you receive to the object you want it to be.
HttpResponseMessage response = client.GetAsync("api/yourcustomobjects").Result;
if (response.IsSuccessStatusCode)
{
var yourcustomobjects = response.Content.ReadAsAsync<IEnumerable<YourCustomObject>>().Result;
foreach (var x in yourcustomobjects)
{
//Call your store method and pass in your own object
SaveCustomObjectToDB(x);
}
}
else
{
//Something has gone wrong, handle it here
}
please note that I use .Result
for the case of the example. You should consider using the async
await
pattern here.
You could try:
alist[:] = []
Which means: Splice in the list []
(0 elements) at the location [:]
(all indexes from start to finish)
The [:] is the slice operator. See this question for more information.
The ISO C99 standard specifies that these macros must only be defined if explicitly requested.
#define __STDC_FORMAT_MACROS
#include <inttypes.h>
... now PRIu64 will work
If you want to run the script file then use below in cmd
sqlcmd -U user -P pass -S servername -d databasename -i "G:\Hiren\Lab_Prodution.sql"
You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.
from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] ) # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] ) # Creates a matrix (like a row vector).
print A.T # Transpose of A.
print A*x # Matrix multiplication of A and x.
print A.I # Inverse of A.
print linalg.solve(A, x) # Solve the linear equation system.
You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.
Would like to take credit for this but I found a solution here:
https://teamtreehouse.com/forum/how-do-you-make-a-svg-clickable
add the following to the css for the anchor:
a.svg {
position: relative;
display: inline-block;
}
a.svg:after {
content: "";
position: absolute;
top: 0;
right: 0;
bottom: 0;
left:0;
}
<a href="#" class="svg">
<object data="random.svg" type="image/svg+xml">
<img src="random.jpg" />
</object>
</a>
Link works on the svg and on the fallback.
The following solved my problem of converting string into date
package main
import (
"fmt"
"time"
)
func main() {
value := "Thu, 05/19/11, 10:47PM"
// Writing down the way the standard time would look like formatted our way
layout := "Mon, 01/02/06, 03:04PM"
t, _ := time.Parse(layout, value)
fmt.Println(t)
}
// => "Thu May 19 22:47:00 +0000 2011"
This is caused when your request response is not received in given time(by timeout
request module option).
Basically to catch that error first, you need to register a handler on error
, so the unhandled error won't be thrown anymore: out.on('error', function (err) { /* handle errors here */ })
. Some more explanation here.
In the handler you can check if the error is ETIMEDOUT and apply your own logic: if (err.message.code === 'ETIMEDOUT') { /* apply logic */ }
.
If you want to request for the file again, I suggest using node-retry or node-backoff modules. It makes things much simpler.
If you want to wait longer, you can set timeout
option of request yourself. You can set it to 0 for no timeout.

NumPy's main object is the homogeneous multidimensional array. In Numpy dimensions are called axes. The number of axes is rank. Numpy's array class is called ndarray. It is also known by the alias array. The more important attributes of an ndarray object are:
ndarray.ndim
the number of axes (dimensions) of the array. In the Python world, the number of dimensions is referred to as rank.ndarray.shape
the dimensions of the array. This is a tuple of integers indicating the size of the array in each dimension. For a matrix with n rows and m columns, shape will be (n,m). The length of the shape tuple is therefore the rank, or number of dimensions, ndim.ndarray.size
the total number of elements of the array. This is equal to the product of the elements of shape.

req.open("POST", url2get, false); // 3rd param is whether "async"
}
catch(err) {
alert("couldnt complete request. Is JS enabled for that domain?\\n\\n" + err.message);
return false;
}
req.send(sendstr); // param string only used for POST
if (req.readyState == 4) { // only if req is "loaded"
if (req.status == 200) // only if "OK"
{ return req.responseText ; }
else { return "XHR error: " + req.status +" "+req.statusText; }
}
}
alert("req for getAsync is undefined");
}
var var_str = "var1=" + var1 + "&var2=" + var2;
var ret = postAsync(url, var_str) ;
// hint: encodeURIComponent()
if (ret.match(/^XHR error/)) {

return;
}
In your case:
var var_str = "video_time=" + document.getElementById('video_time').value
+ "&video_id=" + document.getElementById('video_id').value;
It's simple to convert the Unix timestamp into the desired format. Lets suppose _ts is the Unix timestamp in long
let date = NSDate(timeIntervalSince1970: _ts)
let dayTimePeriodFormatter = NSDateFormatter()
dayTimePeriodFormatter.dateFormat = "MMM dd YYYY hh:mm a"
let dateString = dayTimePeriodFormatter.stringFromDate(date)
print( " _ts value is \(_ts)")
print( " _ts value is \(dateString)")
To understand how a docker image was built, use the
docker history --no-trunc
command.
You can build a docker file from an image, but it will not contain everything you would want to fully understand how the image was generated. Reasonably what you can extract is the MAINTAINER, ENV, EXPOSE, VOLUME, WORKDIR, ENTRYPOINT, CMD, and ONBUILD parts of the dockerfile.
The following script should work for you:
#!/bin/bash
docker history --no-trunc "$1" | \
sed -n -e 's,.*/bin/sh -c #(nop) \(MAINTAINER .*[^ ]\) *0 B,\1,p' | \
head -1
docker inspect --format='{{range $e := .Config.Env}}
ENV {{$e}}
{{end}}{{range $e,$v := .Config.ExposedPorts}}
EXPOSE {{$e}}
{{end}}{{range $e,$v := .Config.Volumes}}
VOLUME {{$e}}
{{end}}{{with .Config.User}}USER {{.}}{{end}}
{{with .Config.WorkingDir}}WORKDIR {{.}}{{end}}
{{with .Config.Entrypoint}}ENTRYPOINT {{json .}}{{end}}
{{with .Config.Cmd}}CMD {{json .}}{{end}}
{{with .Config.OnBuild}}ONBUILD {{json .}}{{end}}' "$1"
I use this as part of a script to rebuild running containers as images: https://github.com/docbill/docker-scripts/blob/master/docker-rebase
The Dockerfile is mainly useful if you want to be able to repackage an image.
The thing to keep in mind, is a docker image can actually just be the tar backup of a real or virtual machine. I have made several docker images this way. Even the build history shows me importing a huge tar file as the first step in creating the image...
Use an html button and javascript? in javascript, window.location
is used to change the url location of the current window, while window.open
will open a new one
<input type="button" onclick="window.open('newPage.aspx', 'newPage');" />
Edit: Ah, just found this: If the ID of your form tag is form1
, set this attribute in your asp button
OnClientClick="form1.target ='_blank';"
I had the same Error and my Problem was, that I had my php-file in my encrypted home-directory. And I run my fpm with the www-data user and this user can't read the php-files even if the permissions on the file were right. The solutioin was that I run fpm with the user who owns the home-directory. This can be changed in folowing file:
/etc/php5/fpm/pool.d/www.conf
hope this will help you :)
This Actually worked for me in chrome. I was pretty suprised.
jQuery(document).bind("keyup keydown", function(e){
if(e.ctrlKey && e.keyCode == 80){
Print(); e.preventDefault();
}
});
Where Print is a function I wrote that calls window.print(); It also works as a pure blocker if you disable Print();
As noted here by user3017502
window.print() will pause so you can add an onPrintFinish or onPrintBegin like this
function Print(){
onPrintBegin
window.print();
onPrintFinish();
}
You could use this to sort all kind of Objects
sort(T[] a, Comparator<? super T> c)
Arrays.sort(a, Collections.reverseOrder());
Arrays.sort()
cannot be used directly to sort primitive arrays in descending order. If you try to call the Arrays.sort()
method by passing reverse Comparator defined by Collections.reverseOrder()
, it will throw the error
no suitable method found for sort(int[],comparator)
That will work fine with 'Array of Objects' such as Integer array but will not work with a primitive array such as int array.
The only way to sort a primitive array in descending order is, first sort the array in ascending order and then reverse the array in place. This is also true for two-dimensional primitive arrays.
Johan is close - it depends on the hardware manufacturer. For example, Samsung Galaxy S phones uses Samsung RFS (proprietary). However, the Nexus S (also made by Samsung) with Android 2.3 uses Ext4 (presumably because Google told them to - the Nexus S is the current Google experience phone). Many community developers have also started moving to Ext4 because of this shift.
I ran into this issue also and my solution was to verify I was integrating the appropriate client code for the version I had selected.
In my case, I had selected reCAPTCHA v3 but was taking client integration code for v2.
V3 looks like this:
<script src="https://www.google.com/recaptcha/api.js?render=reCAPTCHA_site_key"></script>
<script>
grecaptcha.ready(function() {
grecaptcha.execute('reCAPTCHA_site_key', {action: 'homepage'}).then(function(token) {
...
});
});
</script>
V2 code looks like this:
<html>
<head>
<title>reCAPTCHA demo: Simple page</title>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<form action="?" method="POST">
<div class="g-recaptcha" data-sitekey="your_site_key"></div>
<br/>
<input type="submit" value="Submit">
</form>
</body>
</html>
As for which version you have, this will be what you decided at the start of your reCAPTCHA account setup.
Here are some ways to edit the text and the size of the box:
rows="insertNumber"
cols="insertNumber"
style="font-size:12pt"
Example:
<textarea rows="5" cols="30" style="font-size: 12pt" id="myText">Enter
Text Here</textarea>
You can declare an event with the following code:
public event EventHandler MyOwnEvent;
A custom delegate type instead of EventHandler can be used if needed.
You can find detailed information/tutorials on the use of events in .NET in the article Events Tutorial (MSDN).

var c = new C();_x000D_
c.modify = function(){_x000D_
c.x = 123;_x000D_

}_x000D_
c.sum();_x000D_

Yes, setState() is asynchronous.
From the link: https://reactjs.org/docs/react-component.html#setstate
- React does not guarantee that the state changes are applied immediately.
- setState() does not always immediately update the component.
- Think of setState() as a request rather than an immediate command to update the component.
Because they think
From the link: https://github.com/facebook/react/issues/11527#issuecomment-360199710
... we agree that setState() re-rendering synchronously would be inefficient in many cases
Asynchronous setState() makes life very difficult for those getting started and even experienced unfortunately:
- unexpected rendering issues: delayed rendering or no rendering (based on program logic)
- passing parameters is a big deal
among other issues.
Below example helped:
// call doMyTask1 - here we set state
// then after state is updated...
// call to doMyTask2 to proceed further in program
constructor(props) {
// ..
// This binding is necessary to make `this` work in the callback
this.doMyTask1 = this.doMyTask1.bind(this);
this.doMyTask2 = this.doMyTask2.bind(this);
}
function doMyTask1(myparam1) {
// ..
this.setState(
{
mystate1: 'myvalue1',
mystate2: 'myvalue2'
// ...
},
() => {
this.doMyTask2(myparam1);
}
);
}
function doMyTask2(myparam2) {
// ..
}
Hope that helps.
I used Mike Hansen's solution, it is great. I modified his solution in one point, instead of replacing parts of the string I modified the XML-attribute. Maybe it is too much of an effort when you can modify the string but anyway, here is my solution for that. This could easily be further modified to change the table etc. too, which is very nice imho.
What was helpful for me was a helper sub to write the XML to a file so I could check the structure and content of it:
Sub writeStringToFile(strPath As String, strText As String)
'#### writes a given string into a given filePath, overwriting a document if it already exists
Dim objStream
Set objStream = CreateObject("ADODB.Stream")
objStream.Charset = "utf-8"
objStream.Open
objStream.WriteText strText
objStream.SaveToFile strPath, 2
End Sub
The XML of an/my ImportExportSpecification for a table with 2 columns looks like this:
<?xml version="1.0"?>
<ImportExportSpecification Path="mypath\mydocument.xlsx" xmlns="urn:www.microsoft.com/office/access/imexspec">
<ImportExcel FirstRowHasNames="true" AppendToTable="myTableName" Range="myExcelWorksheetName">
<Columns PrimaryKey="{Auto}">
<Column Name="Col1" FieldName="SomeFieldName" Indexed="NO" SkipColumn="false" DataType="Double"/>
<Column Name="Col2" FieldName="SomeFieldName" Indexed="NO" SkipColumn="false" DataType="Text"/>
</Columns>
</ImportExcel>
</ImportExportSpecification>
Then I wrote a function to modify the path. I left out error-handling here:
Function modifyDataSourcePath(strNewPath As String, strXMLSpec As String) As String
'#### Changes the path-name of an import-export specification
Dim xDoc As MSXML2.DOMDocument60
Dim childNodes As IXMLDOMNodeList
Dim nodeImExSpec As MSXML2.IXMLDOMNode
Dim childNode As MSXML2.IXMLDOMNode
Dim attributesImExSpec As IXMLDOMNamedNodeMap
Dim attributeImExSpec As IXMLDOMAttribute
Set xDoc = New MSXML2.DOMDocument60
xDoc.async = False: xDoc.validateOnParse = False
xDoc.LoadXML (strXMLSpec)
Set childNodes = xDoc.childNodes
For Each childNode In childNodes
If childNode.nodeName = "ImportExportSpecification" Then
Set nodeImExSpec = childNode
Exit For
End If
Next childNode
Set attributesImExSpec = nodeImExSpec.Attributes
For Each attributeImExSpec In attributesImExSpec
If attributeImExSpec.nodeName = "Path" Then
attributeImExSpec.Value = strNewPath
Exit For
End If
Next attributeImExSpec
modifyDataSourcePath = xDoc.XML
End Function
I use this in Mike's code before the newSpec is executed and instead of the replace statement. Also I write the XML-string into an XML-file in a location relative to the database but that line is optional:
Set myNewSpec = CurrentProject.ImportExportSpecifications.item("TemporaryImport")
myNewSpec.XML = modifyDataSourcePath(myPath, myNewSpec.XML)
Call writeStringToFile(Application.CurrentProject.Path & "\impExpSpec.xml", myNewSpec.XML)
myNewSpec.Execute
@Html.CheckBox("yourId", true, new { value = Model.Ischecked })
This will certainly work
To build upon @6twenty's answer...I prefer panTo(LatLng) over setCenter(LatLng) as panTo animates for smoother transition to center "if the change is less than both the width and height of the map". https://developers.google.com/maps/documentation/javascript/reference#Map
The below uses Google Maps API v3.
var marker = new google.maps.Marker({
position: new google.maps.LatLng(latitude, longitude),
title: markerTitle,
map: map,
});
google.maps.event.addListener(marker, 'click', function () {
map.panTo(marker.getPosition());
//map.setCenter(marker.getPosition()); // sets center without animation
});
It is “old-fashioned” way to specify ranges of revisions you wish to merge. With 1.5+ you can use:
svn merge HEAD url/of/trunk path/to/branch/wc
You can use Android Intents library for opening your application page at Google Play like that:
Intent intent = IntentUtils.openPlayStore(getApplicationContext());
startActivity(intent);
Try this way:
<%= f.select(:object_field, ['Item 1', ...], {}, { :class => 'my_style_class' }) %>
select
helper takes two options hashes, one for select, and the second for html options. So all you need is to give default empty options as first param after list of items and then add your class to html_options
.

see this page Entity Framework and AsNoTracking
Entity Framework exposes a number of performance tuning options to help you optimise the performance of your applications. One of these tuning options is .AsNoTracking()
. This optimisation allows you to tell Entity Framework
not to track the results of a query. This means that Entity Framework
performs no additional processing or storage of the entities which are returned by the query. However, it also means that you can't update these entities without reattaching them to the tracking graph.
there are significant performance gains to be had by using AsNoTracking
add KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha??1 to your sshd_config on the server.
This worked, but make sure you restart sshd: sudo service sshd restart
-u: disabled by default. When activated, an error message is displayed when using an unconfigured variable.
-v: inactive by default. After activation, the original content of the information will be displayed (without variable resolution) before the information is output.
-x: inactive by default. If activated, the command content will be displayed before the command is run (after variable resolution, there is a ++ symbol).
Compare the following differences:
/ # set -v && echo $HOME
/root

in map.jsx
or map.js
file, if you exporting as default like:
export default MapComponent;
then you can import it like
import MapComponent from './map'
but if you do not export it as default like this one here
export const MapComponent = () => { ...whatever }
you need to import in inside curly braces like
import { MapComponent } from './map'
like below:
import './css/app.css'
if you are using sass all you need to do is just use sass loader with webpack!

There is also the possibility to use sufficientlysecure.htmltextview.HtmlTextView
Use like below in gradle files:
Project gradle file:
repositories {
jcenter()
}
App gradle file:
dependencies {
implementation 'org.sufficientlysecure:html-textview:3.9'
}
Inside xml file replace your textView with:
<org.sufficientlysecure.htmltextview.HtmlTextView
android:id="@+id/allNewsBlockTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:textColor="#000"
android:textSize="18sp"
app:htmlToString="@{detailsViewModel.selectedText}" />
Last line above is if you use Binding adapters where the code will be like:
@BindingAdapter("htmlToString")
fun bindTextViewHtml(textView: HtmlTextView, htmlValue: String) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setHtml(
htmlValue,
HtmlHttpImageGetter(textView, "n", true)
);
} else {
textView.setHtml(
htmlValue,
HtmlHttpImageGetter(textView, "n", true)
);
}
}

The problem is that your class contains a managed RAW pointer but does not implement the rule of three (five in C++11). As a result you are getting (expectedly) a double delete because of copying.
If you are learning you should learn how to implement the rule of three (five). But that is not the correct solution to this problem. You should be using standard container objects rather than try to manage your own internal container. The exact container will depend on what you are trying to do but std::vector is a good default (and you can change afterwords if it is not opimal).
#include <queue>
#include <vector>
class Test{
std::vector<int> myArray;
public:
Test(): myArray(10){
}
};
int main(){
queue<Test> q
Test t;
q.push(t);
}
The reason you should use a standard container is the separation of concerns
. Your class should be concerned with either business logic or resource management (not both). Assuming Test
is some class you are using to maintain some state about your program then it is business logic and it should not be doing resource management. If on the other hand Test
is supposed to manage an array then you probably need to learn more about what is available inside the standard library.
I've found a temporary solution that will at least let me process this job. I wrote a short AutoIt script that waits for the "Update Links" window to appear, then clicks the "Don't Update" button. Code is as follows:
while 1
if winexists("Microsoft Excel","This workbook contains links to other data sources.") Then
controlclick("Microsoft Excel","This workbook contains links to other data sources.",2)
EndIf
WEnd
So far this seems to be working. I'd really like to find a solution that's entirely VBA, however, so that I can make this a standalone application.
Here was my solution:
Markup:
<div id="name" disabled="disabled">
Javascript:
document.getElementById("name").disabled = true;
This the best solution for my applications - hope this helps!
you can use the new push/pop state functions in the history manipulation API.
The URI "file:///android_asset/"
points to YourProject/app/src/main/assets/
.
Note: android_asset/
uses the singular (asset) and src/main/assets
uses the plural (assets).
Suppose you have a file YourProject/app/src/main/assets/web_thing.html
that you would like to display in a WebView. You can refer to it like this:
WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/web_thing.html");
The snippet above could be located in your Activity class, possibly in the onCreate
method.
Here is a guide to the overall directory structure of an android project, that helped me figure out this answer.
You should be able to do this with the keyup event. To be specific, event.target
should point at the selected element and event.target.href
will give you the href-value of that element. See mdn for more information.
The following code is jQuery, but apart from the boilerplate code, the rest is the same in pure javascript. This is a keyup
handler that is bound to every link tag.
$('a').on( 'keyup', function( e ) {
if( e.which == 9 ) {
console.log( e.target.href );
}
} );

getDay()
returns the day of the week. To get the date, use date.getDate()
. getMonth()
retrieves the month, but month is zero based, so using getMonth()+1
should give you the right month. Time value seems to be ok here, albeit the hour is 23 here (GMT+1). If you want universal values, add UTC
to the methods (e.g. date.getUTCFullYear()
, date.getUTCHours()
)
var timestamp = 1301090400,
date = new Date(timestamp * 1000),
datevalues = [
date.getFullYear(),
date.getMonth()+1,
date.getDate(),
date.getHours(),
date.getMinutes(),
date.getSeconds(),
];
alert(datevalues); //=> [2011, 3, 25, 23, 0, 0]
If that <p>
tag is created from JavaScript, then you do have another option: use JSS to programmatically insert stylesheets into the document head. It does support '&:hover'
. https://cssinjs.org/
RFC 3339 is mostly a profile of ISO 8601, but is actually inconsistent with it in borrowing the "-00:00" timezone specification from RFC 2822. This is described in the Wikipedia article.
This also works if you are looping over an object.
unset($object->$key);
No need to use brackets.
