Another way to do this is to reassign df based on a cross section of df, using the .xs method.

>>> df

    a
    b   c
0   1   2
1   3   4

>>> df = df.xs('a', axis=1, drop_level=True)

    # 'a' : key on which to get cross section
    # axis=1 : get cross section of column
    # drop_level=True : returns cross section without the multilevel index

>>> df

    b   c
0   1   2
1   3   4

In my case, all console messages were not showing because I had left a string in the "filter" textbox.

Remove the filter it by clicking the X as shown:

I just wonder why nobody uses or recommends the way I prefer to debug an array:

error_log(json_encode($array));

Next to my browser I tail my server log in the console eg.

tail -f /var/log/apache2/error.log

Set environment variables and use headers to receive them:

You can create new environment variables with RewriteRule lines, as mentioned by OP:

RewriteRule ^(.*) - [E=TEST0:%{DOCUMENT_ROOT}/blog/html_cache/$1.html]

But if you can't get a server-side script to work, how can you then read this environment variable? One solution is to set a header:

Header set TEST_FOOBAR "%{REDIRECT_TEST0}e"

The value accepts format specifiers, including the %{NAME}e specifier for environment variables (don't forget the lowercase e). Sometimes, you'll need to add the REDIRECT_ prefix, but I haven't worked out when the prefix gets added and when it doesn't.

I needed a multilevel dropdown menu in css. I couldn't find an error-free menu that I searched. Then I created a menu instance using the Css hover transition effect.I hope it will be useful for users.

Css codes:

A very common usecase of calc is take 100% width and adding some margin around the element.

One can do so with:

@someMarginVariable = 15px;

margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);

I am using Windows 8.1 environment. I had the same problem while running my first java program after installing Eclipse recently. I had installed java on d drive at d:\java. But Eclipse was looking at the default installation c:\programfiles\java. I did the following:

1. Modified my eclipse.ini file and added the following after open:

   -vm
   d:\java\jdk1.8.0_161\bin 
   

2. While creating the java program I have to unselect default build path and then select d:\java.

After this, the program ran well and got the hello world to work.

this could be a solution?

declare @step2cmd nvarchar(200)
DECLARE @rcount NUMERIC(18,0)   
set @step2cmd = 'select count(*) from uat.ap.ztscm_protocollo' --+ @nometab
EXECUTE @rcount=sp_executesql @step2cmd
select @rcount

It looks like Google actively frowns on using IP-to-location mapping:

https://developers.google.com/maps/articles/geolocation?hl=en

That article encourages using the W3C geolocation API. I was a little skeptical, but it looks like almost every major browser already supports the geolocation API:

http://caniuse.com/geolocation

//This will sort your array
function SortByName(a, b){
  var aName = a.name.toLowerCase();
  var bName = b.name.toLowerCase(); 
  return ((aName < bName) ? -1 : ((aName > bName) ? 1 : 0));
}

array.sort(SortByName);

Hope this is helpfull

You're trying to use key functions with lambda functions.

Python and other languages like C# or F# use lambda functions.

Also, when it comes to key functions and according to the documentation

Both list.sort() and sorted() have a key parameter to specify a function to be called on each list element prior to making comparisons.

...

The value of the key parameter should be a function that takes a single argument and returns a key to use for sorting purposes. This technique is fast because the key function is called exactly once for each input record.

So, key functions have a parameter key and it can indeed receive a lambda function.

In Real Python there's a nice example of its usage. Let's say you have the following list

ids = ['id1', 'id100', 'id2', 'id22', 'id3', 'id30']

and want to sort through its "integers". Then, you'd do something like

sorted_ids = sorted(ids, key=lambda x: int(x[2:])) # Integer sort

and printing it would give

['id1', 'id2', 'id3', 'id22', 'id30', 'id100']

In your particular case, you're only missing to write key= before lambda. So, you'd want to use the following

a = sorted(a, key=lambda x: x.modified, reverse=True)

I can't say for sure what the problem is. Could be some bad character, could be the spaces you have left at the beginning and at the end, no idea.

Anyway, you shouldn't hardcode your JSON as strings as you have done. Instead the proper way to send JSON data to the server is to use a JSON serializer:

data: JSON.stringify({ name : "AA" }),

Now on the server also make sure that you have the proper view model expecting to receive this input:

public class UserViewModel
{
    public string Name { get; set; }
}

and the corresponding action:

[HttpPost]
public ActionResult SaveProduct(UserViewModel model)
{
    ...
}

Now there's one more thing. You have specified dataType: 'json'. This means that you expect that the server will return a JSON result. The controller action must return JSON. If your controller action returns a view this could explain the error you are getting. It's when jQuery attempts to parse the response from the server:

[HttpPost]
public ActionResult SaveProduct(UserViewModel model)
{
    ...
    return Json(new { Foo = "bar" });
}

This being said, in most cases, usually you don't need to set the dataType property when making AJAX request to an ASP.NET MVC controller action. The reason for this is because when you return some specific ActionResult (such as a ViewResult or a JsonResult), the framework will automatically set the correct Content-Type response HTTP header. jQuery will then use this header to parse the response and feed it as parameter to the success callback already parsed.

I suspect that the problem you are having here is that your server didn't return valid JSON. It either returned some ViewResult or a PartialViewResult, or you tried to manually craft some broken JSON in your controller action (which obviously you should never be doing but using the JsonResult instead).

One more thing that I just noticed:

async: false,

Please, avoid setting this attribute to false. If you set this attribute to false you are are freezing the client browser during the entire execution of the request. You could just make a normal request in this case. If you want to use AJAX, start thinking in terms of asynchronous events and callbacks.

As an alternative to using the import approach described in several answers, have a look a the configparser module.

The ConfigParser class implements a basic configuration file parser language which provides a structure similar to what you would find on Microsoft Windows INI files. You can use this to write Python programs which can be customized by end users easily.

Also if you want selected field from table and aggregated then as array .

SELECT json_agg(json_build_object('data_a',a,
                                  'data_b',b,
))  from t;

The result will come .

 [{'data_a':1,'data_b':'value1'}
  {'data_a':2,'data_b':'value2'}]

While this will render in a web browser, beware that:
??Nesting an html button in an html a (or vice-versa) is not valid html ??. If you want to keep your html semantic to screen readers, use another approach.

Do wrapping in the reverse way and you get the original button with the Link attached. No CSS changes required.

 <Link to="/dashboard">
     <button type="button">
          Click Me!
     </button>
 </Link>

Here button is HTML button. It is also applicable to the components imported from third party libraries like Semantic-UI-React.

 import { Button } from 'semantic-ui-react'
 ... 
 <Link to="/dashboard">
     <Button style={myStyle}>
        <p>Click Me!</p>
     </Button>
 </Link>

jQuery Mobile has a datepicker too. Source

Just include the following files,

  <script src="jQuery.ui.datepicker.js"></script>
  <script src="jquery.ui.datepicker.mobile.js"></script>

I use the lattice package for almost everything I plot in R and it has a corresponing plot to persp called wireframe. Let data be the way Sven defined it.

wireframe(z ~ x * y, data=data)

Or how about this (modification of fig 6.3 in Deepanyan Sarkar's book):

p <- wireframe(z ~ x * y, data=data)
npanel <- c(4, 2)
rotx <- c(-50, -80)
rotz <- seq(30, 300, length = npanel[1]+1)
update(p[rep(1, prod(npanel))], layout = npanel,
    panel = function(..., screen) {
        panel.wireframe(..., screen = list(z = rotz[current.column()],
                                           x = rotx[current.row()]))
    })

Update: Plotting surfaces with OpenGL

Since this post continues to draw attention I want to add the OpenGL way to make 3-d plots too (as suggested by @tucson below). First we need to reformat the dataset from xyz-tripplets to axis vectors x and y and a matrix z.

x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z

library(rgl)
persp3d(x, y, z, col="skyblue")

This image can be freely rotated and scaled using the mouse, or modified with additional commands, and when you are happy with it you save it using rgl.snapshot.

rgl.snapshot("myplot.png")

In the server, do something like this:

Suppose

String data = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAPAAAADwCAYAAAA+VemSAAAgAEl...=='

Then:

String base64Image = data.split(",")[1];
byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(base64Image);

Then you can do whatever you like with the bytes like:

BufferedImage img = ImageIO.read(new ByteArrayInputStream(imageBytes));

You can simply use datetime diff and format for calculating difference.

<?php
$datetime1 = new DateTime('2009-10-11 12:12:00');
$datetime2 = new DateTime('2009-10-13 10:12:00');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%Y-%m-%d %H:%i:%s');
?>

For more information OF DATETIME format, refer: here
You can change the interval format in the way,you want.

Here is the working example

P.S. These features( diff() and format()) work with >=PHP 5.3.0 only

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

As mentioned by @Brent in the comment of @maxymoo's answer, you can try

df.limit(10).toPandas()

to get a prettier table in Jupyter. But this can take some time to run if you are not caching the spark dataframe. Also, .limit() will not keep the order of original spark dataframe.

For a three dimensional array you could try:

for c in array.transpose(1, 0, 2):
    do_stuff(c)

See the docs on how array.transpose works. Basically you are specifying which dimension to shift. In this case we are shifting the second dimension (e.g. columns) to the first dimension.

XSLT 2

Date functions are available natively, such as:

<xsl:value-of  select="current-dateTime()"/>

There is also current-date() and current-time().

XSLT 1

Use the EXSLT date and times extension package.

1. Download the date and times package from GitHub.
2. Extract date.xsl to the location of your XSL files.
3. Set the stylesheet header.
4. Import date.xsl.

For example:

<xsl:stylesheet version="1.0" 
    xmlns:date="http://exslt.org/dates-and-times" 
    extension-element-prefixes="date"
    ...>

    <xsl:import href="date.xsl" />

    <xsl:template match="//root">
       <xsl:value-of select="date:date-time()"/>
    </xsl:template>
</xsl:stylesheet>

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

You are opening the file as "w", which stands for writable.

Using "w" you won't be able to read the file. Use the following instead:

file = open("File.txt","r")

Additionally, here are the other options:

"r"   Opens a file for reading only.
"r+"  Opens a file for both reading and writing.
"rb"  Opens a file for reading only in binary format.
"rb+" Opens a file for both reading and writing in binary format.
"w"   Opens a file for writing only.
"a"   Open for writing.  The file is created if it does not exist.
"a+"  Open for reading and writing.  The file is created if it does not exist.

An example of where the console will return ReferenceError is putting a function inside a JQuery document ready function

//this will fail
$(document).ready(function () {
          myFunction(alert('doing something!'));
          //other stuff
}

To succeed move the function outside the document ready function

//this will work
myFunction(alert('doing something!'));
$(document).ready(function () {

          //other stuff
}

Then in the console window, type the function name with the '()' to execute the function

myFunction()

Also of use is being able to print out the function body to remind yourself what the function does. Do this by leaving off the '()' from the function name

function myFunction(alert('doing something!'))

Of course if you need the function to be registered after the document is loaded then you couldn't do this. But you might be able to work around that.

If you're not too worried in accuracy after days, you can simply do the maths

function timeSince(when) { // this ignores months
    var obj = {};
    obj._milliseconds = (new Date()).valueOf() - when.valueOf();
    obj.milliseconds = obj._milliseconds % 1000;
    obj._seconds = (obj._milliseconds - obj.milliseconds) / 1000;
    obj.seconds = obj._seconds % 60;
    obj._minutes = (obj._seconds - obj.seconds) / 60;
    obj.minutes = obj._minutes % 60;
    obj._hours = (obj._minutes - obj.minutes) / 60;
    obj.hours = obj._hours % 24;
    obj._days = (obj._hours - obj.hours) / 24;
    obj.days = obj._days % 365;
    // finally
    obj.years = (obj._days - obj.days) / 365;
    return obj;
}

then timeSince(pastDate); and use the properties as you like.

Otherwise you can use .getUTC* to calculate it, but note it may be slightly slower to calculate

function timeSince(then) {
    var now = new Date(), obj = {};
    obj.milliseconds = now.getUTCMilliseconds() - then.getUTCMilliseconds();
    obj.seconds = now.getUTCSeconds() - then.getUTCSeconds();
    obj.minutes = now.getUTCMinutes() - then.getUTCMinutes();
    obj.hours = now.getUTCHours() - then.getUTCHours();
    obj.days = now.getUTCDate() - then.getUTCDate();
    obj.months = now.getUTCMonth() - then.getUTCMonth();
    obj.years = now.getUTCFullYear() - then.getUTCFullYear();
    // fix negatives
    if (obj.milliseconds < 0) --obj.seconds, obj.milliseconds = (obj.milliseconds + 1000) % 1000;
    if (obj.seconds < 0) --obj.minutes, obj.seconds = (obj.seconds + 60) % 60;
    if (obj.minutes < 0) --obj.hours, obj.minutes = (obj.minutes + 60) % 60;
    if (obj.hours < 0) --obj.days, obj.hours = (obj.hours + 24) % 24;
    if (obj.days < 0) { // months have different lengths
        --obj.months;
        now.setUTCMonth(now.getUTCMonth() + 1);
        now.setUTCDate(0);
        obj.days = (obj.days + now.getUTCDate()) % now.getUTCDate();
    }
    if (obj.months < 0)  --obj.years, obj.months = (obj.months + 12) % 12;
    return obj;
}

First, what you need to understand the relationships between components. Then you can choose the right method of communication. I will try to explain all the methods that I know and use in my practice for communication between components.

What kinds of relationships between components can there be?

1. Parent > Child

Sharing Data via Input

This is probably the most common method of sharing data. It works by using the @Input() decorator to allow data to be passed via the template.

parent.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'parent-component',
  template: `
    <child-component [childProperty]="parentProperty"></child-component>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent{
  parentProperty = "I come from parent"
  constructor() { }
}

child.component.ts

import { Component, Input } from '@angular/core';

@Component({
  selector: 'child-component',
  template: `
      Hi {{ childProperty }}
  `,
  styleUrls: ['./child.component.css']
})
export class ChildComponent {

  @Input() childProperty: string;

  constructor() { }

}

This is a very simple method. It is easy to use. We can also catch changes to the data in the child component using ngOnChanges.

But do not forget that if we use an object as data and change the parameters of this object, the reference to it will not change. Therefore, if we want to receive a modified object in a child component, it must be immutable.

2. Child > Parent

Sharing Data via ViewChild

ViewChild allows one component to be injected into another, giving the parent access to its attributes and functions. One caveat, however, is that child won’t be available until after the view has been initialized. This means we need to implement the AfterViewInit lifecycle hook to receive the data from the child.

parent.component.ts

import { Component, ViewChild, AfterViewInit } from '@angular/core';
import { ChildComponent } from "../child/child.component";

@Component({
  selector: 'parent-component',
  template: `
    Message: {{ message }}
    <child-compnent></child-compnent>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent implements AfterViewInit {

  @ViewChild(ChildComponent) child;

  constructor() { }

  message:string;

  ngAfterViewInit() {
    this.message = this.child.message
  }
}

child.component.ts

import { Component} from '@angular/core';

@Component({
  selector: 'child-component',
  template: `
  `,
  styleUrls: ['./child.component.css']
})
export class ChildComponent {

  message = 'Hello!';

  constructor() { }

}

Sharing Data via Output() and EventEmitter

Another way to share data is to emit data from the child, which can be listed by the parent. This approach is ideal when you want to share data changes that occur on things like button clicks, form entries, and other user events.

parent.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'parent-component',
  template: `
    Message: {{message}}
    <child-component (messageEvent)="receiveMessage($event)"></child-component>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent {

  constructor() { }

  message:string;

  receiveMessage($event) {
    this.message = $event
  }
}

child.component.ts

import { Component, Output, EventEmitter } from '@angular/core';

@Component({
  selector: 'child-component',
  template: `
      <button (click)="sendMessage()">Send Message</button>
  `,
  styleUrls: ['./child.component.css']
})
export class ChildComponent {

  message: string = "Hello!"

  @Output() messageEvent = new EventEmitter<string>();

  constructor() { }

  sendMessage() {
    this.messageEvent.emit(this.message)
  }
}

3. Siblings

Child > Parent > Child

I try to explain other ways to communicate between siblings below. But you could already understand one of the ways of understanding the above methods.

parent.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'parent-component',
  template: `
    Message: {{message}}
    <child-one-component (messageEvent)="receiveMessage($event)"></child1-component>
    <child-two-component [childMessage]="message"></child2-component>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent {

  constructor() { }

  message: string;

  receiveMessage($event) {
    this.message = $event
  }
}

child-one.component.ts

import { Component, Output, EventEmitter } from '@angular/core';

@Component({
  selector: 'child-one-component',
  template: `
      <button (click)="sendMessage()">Send Message</button>
  `,
  styleUrls: ['./child-one.component.css']
})
export class ChildOneComponent {

  message: string = "Hello!"

  @Output() messageEvent = new EventEmitter<string>();

  constructor() { }

  sendMessage() {
    this.messageEvent.emit(this.message)
  }
}

child-two.component.ts

import { Component, Input } from '@angular/core';

@Component({
  selector: 'child-two-component',
  template: `
       {{ message }}
  `,
  styleUrls: ['./child-two.component.css']
})
export class ChildTwoComponent {

  @Input() childMessage: string;

  constructor() { }

}

4. Unrelated Components

All the methods that I have described below can be used for all the above options for the relationship between the components. But each has its own advantages and disadvantages.

Sharing Data with a Service

When passing data between components that lack a direct connection, such as siblings, grandchildren, etc, you should be using a shared service. When you have data that should always be in sync, I find the RxJS BehaviorSubject very useful in this situation.

data.service.ts

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable()
export class DataService {

  private messageSource = new BehaviorSubject('default message');
  currentMessage = this.messageSource.asObservable();

  constructor() { }

  changeMessage(message: string) {
    this.messageSource.next(message)
  }

}

first.component.ts

import { Component, OnInit } from '@angular/core';
import { DataService } from "../data.service";

@Component({
  selector: 'first-componennt',
  template: `
    {{message}}
  `,
  styleUrls: ['./first.component.css']
})
export class FirstComponent implements OnInit {

  message:string;

  constructor(private data: DataService) {
      // The approach in Angular 6 is to declare in constructor
      this.data.currentMessage.subscribe(message => this.message = message);
  }

  ngOnInit() {
    this.data.currentMessage.subscribe(message => this.message = message)
  }

}

second.component.ts

import { Component, OnInit } from '@angular/core';
import { DataService } from "../data.service";

@Component({
  selector: 'second-component',
  template: `
    {{message}}
    <button (click)="newMessage()">New Message</button>
  `,
  styleUrls: ['./second.component.css']
})
export class SecondComponent implements OnInit {

  message:string;

  constructor(private data: DataService) { }

  ngOnInit() {
    this.data.currentMessage.subscribe(message => this.message = message)
  }

  newMessage() {
    this.data.changeMessage("Hello from Second Component")
  }

}

Sharing Data with a Route

Sometimes you need not only pass simple data between component but save some state of the page. For example, we want to save some filter in the online market and then copy this link and send to a friend. And we expect it to open the page in the same state as us. The first, and probably the quickest, way to do this would be to use query parameters.

Query parameters look more along the lines of /people?id= where id can equal anything and you can have as many parameters as you want. The query parameters would be separated by the ampersand character.

When working with query parameters, you don’t need to define them in your routes file, and they can be named parameters. For example, take the following code:

page1.component.ts

import {Component} from "@angular/core";
import {Router, NavigationExtras} from "@angular/router";

@Component({
    selector: "page1",
  template: `
    <button (click)="onTap()">Navigate to page2</button>
  `,
})
export class Page1Component {

    public constructor(private router: Router) { }

    public onTap() {
        let navigationExtras: NavigationExtras = {
            queryParams: {
                "firstname": "Nic",
                "lastname": "Raboy"
            }
        };
        this.router.navigate(["page2"], navigationExtras);
    }

}

In the receiving page, you would receive these query parameters like the following:

page2.component.ts

import {Component} from "@angular/core";
import {ActivatedRoute} from "@angular/router";

@Component({
    selector: "page2",
    template: `
         <span>{{firstname}}</span>
         <span>{{lastname}}</span>
      `,
})
export class Page2Component {

    firstname: string;
    lastname: string;

    public constructor(private route: ActivatedRoute) {
        this.route.queryParams.subscribe(params => {
            this.firstname = params["firstname"];
            this.lastname = params["lastname"];
        });
    }

}

NgRx

The last way, which is more complicated but more powerful, is to use NgRx. This library is not for data sharing; it is a powerful state management library. I can't in a short example explain how to use it, but you can go to the official site and read the documentation about it.

To me, NgRx Store solves multiple issues. For example, when you have to deal with observables and when responsibility for some observable data is shared between different components, the store actions and reducer ensure that data modifications will always be performed "the right way".

It also provides a reliable solution for HTTP requests caching. You will be able to store the requests and their responses so that you can verify that the request you're making does not have a stored response yet.

You can read about NgRx and understand whether you need it in your app or not:

• Angular Service Layers: Redux, RxJs and Ngrx Store - When to Use a Store And Why?
• Ngrx Store - An Architecture Guide

Finally, I want to say that before choosing some of the methods for sharing data you need to understand how this data will be used in the future. I mean maybe just now you can use just an @Input decorator for sharing a username and surname. Then you will add a new component or new module (for example, an admin panel) which needs more information about the user. This means that may be a better way to use a service for user data or some other way to share data. You need to think about it more before you start implementing data sharing.

We are using the following that works both python 2 and python 3

#Works in Python 2 and 3:
try: input = raw_input
except NameError: pass
print(input("Enter your name: "))

Your

$email_to = "[email protected], [email protected], [email protected]"

Needs to be a comma delimited list of email adrresses.

mail($email_to, $email_subject, $thankyou);

The short answer is no: MySQL does not allow you to add a WHERE clause to the TRUNCATE statement. Here's MySQL's documentation about the TRUNCATE statement.

But the good news is that you can (somewhat) work around this limitation.

Simple, safe, clean but slow solution using DELETE

First of all, if the table is small enough, simply use the DELETE statement (it had to be mentioned):

1. LOCK TABLE my_table WRITE;
2. DELETE FROM my_table WHERE my_date<DATE_SUB(NOW(), INTERVAL 1 MONTH);
3. UNLOCK TABLES;

The LOCK and UNLOCK statements are not compulsory, but they will speed things up and avoid potential deadlocks.

Unfortunately, this will be very slow if your table is large... and since you are considering using the TRUNCATE statement, I suppose it's because your table is large.

So here's one way to solve your problem using the TRUNCATE statement:

Simple, fast, but unsafe solution using TRUNCATE

1. CREATE TABLE my_table_backup AS
      SELECT * FROM my_table WHERE my_date>=DATE_SUB(NOW(), INTERVAL 1 MONTH);
2. TRUNCATE my_table;
3. LOCK TABLE my_table WRITE, my_table_backup WRITE;
4. INSERT INTO my_table SELECT * FROM my_table_backup;
5. UNLOCK TABLES;
6. DROP TABLE my_table_backup;

Unfortunately, this solution is a bit unsafe if other processes are inserting records in the table at the same time:

• any record inserted between steps 1 and 2 will be lost
• the TRUNCATE statement resets the AUTO-INCREMENT counter to zero. So any record inserted between steps 2 and 3 will have an ID that will be lower than older IDs and that might even conflict with IDs inserted at step 4 (note that the AUTO-INCREMENT counter will be back to it's proper value after step 4).

Unfortunately, it is not possible to lock the table and truncate it. But we can (somehow) work around that limitation using RENAME.

Half-simple, fast, safe but noisy solution using TRUNCATE

1. RENAME TABLE my_table TO my_table_work;
2. CREATE TABLE my_table_backup AS
     SELECT * FROM my_table_work WHERE my_date>DATE_SUB(NOW(), INTERVAL 1 MONTH);
3. TRUNCATE my_table_work;
4. LOCK TABLE my_table_work WRITE, my_table_backup WRITE;
5. INSERT INTO my_table_work SELECT * FROM my_table_backup;
6. UNLOCK TABLES;
7. RENAME TABLE my_table_work TO my_table;
8. DROP TABLE my_table_backup;

This should be completely safe and quite fast. The only problem is that other processes will see table my_table disappear for a few seconds. This might lead to errors being displayed in logs everywhere. So it's a safe solution, but it's "noisy".

Disclaimer: I am not a MySQL expert, so these solutions might actually be crappy. The only guarantee I can offer is that they work fine for me. If some expert can comment on these solutions, I would be grateful.

The easiest way to convert back it in PowerShell

[System.Net.NetworkCredential]::new("", $SecurePassword).Password

NSE website has changed and the older scripts are semi-optimum to current website. This snippet can gather daily details of security. Details include symbol, security type, previous close, open price, high price, low price, average price, traded quantity, turnover, number of trades, deliverable quantities and ratio of delivered vs traded in percentage. These conveniently presented as list of dictionary form.

Python 3.X version with requests and BeautifulSoup

Besides this is relatively modular and ready to use snippet.

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.

All of these solutions suffer from one of two problems. Either the solution isn't perfectly accurate due to rounding errors, leap days and seconds, etc. or you end up looping over the number of days in between your two unknown dates.

This solution solves the first problem, and improves the second by a factor of roughly 365, better if you know what your max range is.

/**
 * @param thisDate
 * @param thatDate
 * @param maxDays
 *            set to -1 to not set a max
 * @returns number of days covered between thisDate and thatDate, inclusive, i.e., counting both
 *          thisDate and thatDate as an entire day. Will short out if the number of days exceeds
 *          or meets maxDays
 */
public static int daysCoveredByDates(Date thisDate, Date thatDate, int maxDays) {
    //Check inputs
    if (thisDate == null || thatDate == null) {
        return -1;
    }

    //Set calendar objects
    Calendar startCal = Calendar.getInstance();
    Calendar endCal = Calendar.getInstance();
    if (thisDate.before(thatDate)) {
        startCal.setTime(thisDate);
        endCal.setTime(thatDate);
    }
    else {
        startCal.setTime(thatDate);
        endCal.setTime(thisDate);
    }

    //Get years and dates of our times.
    int startYear = startCal.get(Calendar.YEAR);
    int endYear = endCal.get(Calendar.YEAR);
    int startDay = startCal.get(Calendar.DAY_OF_YEAR);
    int endDay = endCal.get(Calendar.DAY_OF_YEAR);

    //Calculate the number of days between dates.  Add up each year going by until we catch up to endDate.
    while (startYear < endYear && maxDays >= 0 && endDay - startDay + 1 < maxDays) {
        endDay += startCal.getActualMaximum(Calendar.DAY_OF_YEAR); //adds the number of days in the year startDate is currently in
        ++startYear;
        startCal.set(Calendar.YEAR, startYear); //reup the year
    }
    int days = endDay - startDay + 1;

    //Honor the maximum, if set
    if (maxDays >= 0) {
        days = Math.min(days, maxDays);
    }
    return days;
}

If you need days between dates (uninclusive of the latter date), just get rid of the + 1 when you see endDay - startDay + 1.

We can also make use of below given dependency and plugin in your pom file - I make use of maven. With the use of these you can generate POJO's as per your JSON Schema and then make use of code given below to populate request JSON object via src object specified as parameter to gson.toJson(Object src) or vice-versa. Look at the code below:

Gson gson = new GsonBuilder().create();
String payloadStr = gson.toJson(data.getMerchant().getStakeholder_list());

Gson gson2 = new Gson();
Error expectederr = gson2.fromJson(payloadStr, Error.class);

And the Maven settings:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>1.7.1</version>
</dependency>

<plugin>
    <groupId>com.googlecode.jsonschema2pojo</groupId>
    <artifactId>jsonschema2pojo-maven-plugin</artifactId>
    <version>0.3.7</version>
    <configuration>
        <sourceDirectory>${basedir}/src/main/resources/schema</sourceDirectory>
        <targetPackage>com.example.types</targetPackage>
    </configuration>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Converting the Java project to Maven Project fixed the issue for me. The conversion was done on Eclipse by: Right Click Project -> Configure -> Convert to Maven Project

You could just use: {in and out function callback}

$(".result").hover(function () {
    $(this).toggleClass("result_hover");
 });

For your example, better will be to use CSS pseudo class :hover: {no js/jquery needed}

.result {
    height: 72px;
    width: 100%;
    border: 1px solid #000;
  }
  .result:hover {
    background-color: #000;
  }

SQL Server 2016 Answer

With SQL Server 2016 you can now do (MSDN Source):

DROP VIEW IF EXISTS dbo.MyView

Just create the database using createdb CLI tool:

PGHOST="my.database.domain.com"
PGUSER="postgres"
PGDB="mydb"
createdb -h $PGHOST -p $PGPORT -U $PGUSER $PGDB

If the database exists, it will return an error:

createdb: database creation failed: ERROR:  database "mydb" already exists

The following worked for me

$('.input-group.date').datepicker({
     format: 'dd/mm/yyyy',
     startDate: new Date()
});

if(list.ElementAtOrDefault(2) != null)
{
   // logic
}

ElementAtOrDefault() is part of the System.Linq namespace.

Although you have a List, so you can use list.Count > 2.

Try this

• 1) Window > Preferences > General > Content Types, set UTF-8 as the default encoding for all content types.

• 2) Window > Preferences > General > Workspace, set Text file encoding to Other : UTF-8

In this mode you can find all element which has class active and remove it

try this

$(document).ready(function() {
        $(this.attr('id')).click(function () {
           $(document).find('.active').removeClass('active');
           var DivId = $(this).attr('id');
           alert(DivId);
           $(this).addClass('active');
        });
  });

I also had this issue. I'm using IntelliJ IDEA. I was using src/main/java for configuration files and src/test/java for test files.
Because of this testNG couldn't find the class path. To prevent getting that error need to move all the files from src/main/java to src/test/java or vice versa.

Combining two highly rated answers here into a complete example that is hopefully useful and self-explanatory:

#!/bin/bash

intro="You know what,"
pet1="cat"
pet2="chicken"
pet3="cow"
pet4="dog"
pet5="pig"

# Setting and reading dynamic variables
for i in {1..5}; do
        pet="pet$i"
        declare "sentence$i=$intro I have a pet ${!pet} at home"
done

# Just reading dynamic variables
for i in {1..5}; do
        sentence="sentence$i"
        echo "${!sentence}"
done

echo
echo "Again, but reading regular variables:"
echo $sentence1
echo $sentence2

Internally, SQL Server treats an inline table valued function much like it would a view and treats a multi-statement table valued function similar to how it would a stored procedure.

When an inline table-valued function is used as part of an outer query, the query processor expands the UDF definition and generates an execution plan that accesses the underlying objects, using the indexes on these objects.

For a multi-statement table valued function, an execution plan is created for the function itself and stored in the execution plan cache (once the function has been executed the first time). If multi-statement table valued functions are used as part of larger queries then the optimiser does not know what the function returns, and so makes some standard assumptions - in effect it assumes that the function will return a single row, and that the returns of the function will be accessed by using a table scan against a table with a single row.

Where multi-statement table valued functions can perform poorly is when they return a large number of rows and are joined against in outer queries. The performance issues are primarily down to the fact that the optimiser will produce a plan assuming that a single row is returned, which will not necessarily be the most appropriate plan.

As a general rule of thumb we have found that where possible inline table valued functions should be used in preference to multi-statement ones (when the UDF will be used as part of an outer query) due to these potential performance issues.

NewScores is an alias to Scores table - it looks like you can combine the queries as follows:

SELECT 
    ROW_NUMBER() OVER( ORDER BY NETT) AS Rank, 
    Name, 
    FlagImg, 
    Nett, 
    Rounds 
FROM (
    SELECT 
        Members.FirstName + ' ' + Members.LastName AS Name, 
        CASE 
            WHEN MenuCountry.ImgURL IS NULL THEN 
                '~/images/flags/ismygolf.png' 
            ELSE 
                MenuCountry.ImgURL 
        END AS FlagImg, 
        AVG(CAST(NewScores.NetScore AS DECIMAL(18, 4))) AS Nett, 
        COUNT(Score.ScoreID) AS Rounds 
    FROM 
        Members 
        INNER JOIN 
        Score NewScores
            ON Members.MemberID = NewScores.MemberID 
        LEFT OUTER JOIN MenuCountry 
            ON Members.Country = MenuCountry.ID 
    WHERE 
        Members.Status = 1 
        AND NewScores.InsertedDate >= DATEADD(mm, -3, GETDATE())
    GROUP BY 
        Members.FirstName + ' ' + Members.LastName, 
        MenuCountry.ImgURL
    ) AS Dertbl 
ORDER BY;

I found another case and therefore I thing you are all wrong.

This is what I had:

/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: eggtrayicon.o: undefined reference to symbol 'XFlush'
/usr/lib64/libX11.so.6: error adding symbols: DSO missing from command line

The problem is that the command line DID NOT contain -lX11 - although the libX11.so should be added as a dependency because there were also GTK and GNOME libraries in the arguments.

So, the only explanation for me is that this message might have been intended to help you, but it didn't do it properly. This was probably simple: the library that provides the symbol was not added to the command line.

Please note three important rules concerning linkage in POSIX:

• Dynamic libraries have defined dependencies, so only libraries from the top-dependency should be supplied in whatever order (although after the static libraries)
• Static libraries have just undefined symbols - it's up to you to know their dependencies and supply all of them in the command line
• The order in static libraries is always: requester first, provider follows. Otherwise you'll get undefined symbol message, just like when you forgot to add the library to the command line
• When you specify the library with -l<name>, you never know whether it will take lib<name>.so or lib<name>.a. The dynamic library is preferred, if found, and static libraries only can be enforced by compiler option - that's all. And whether you have any problems as above, it depends on whether you had static or dynamic libraries
• Well, sometimes the dependencies may be lacking in dynamic libraries :D

You need to first transform data1, in your case by calling ToString() on each element.

Use this if you want to return strings.

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);

Use this if you want to return integers.

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
}

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

def plotFigure(data_plot,file_name,order):
    fig = plt.figure(order, figsize=(9, 6))
    ax = fig.add_subplot(111)
    bp = ax.boxplot(data_plot)
    fig.savefig(file_name, bbox_inches='tight')
    plt.close()

There is a JSONObject constructor to turn a String into a JSONObject:

If you're on .NET 3.5 or up, you can use the new System.DirectoryServices.AccountManagement (S.DS.AM) namespace which makes this a lot easier than it used to be.

Read all about it here: Managing Directory Security Principals in the .NET Framework 3.5

Update: older MSDN magazine articles aren't online anymore, unfortunately - you'll need to download the CHM for the January 2008 MSDN magazine from Microsoft and read the article in there.

Basically, you need to have a "principal context" (typically your domain), a user principal, and then you get its groups very easily:

public List<GroupPrincipal> GetGroups(string userName)
{
   List<GroupPrincipal> result = new List<GroupPrincipal>();

   // establish domain context
   PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain);

   // find your user
   UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, userName);

   // if found - grab its groups
   if(user != null)
   {
      PrincipalSearchResult<Principal> groups = user.GetAuthorizationGroups();

      // iterate over all groups
      foreach(Principal p in groups)
      {
         // make sure to add only group principals
         if(p is GroupPrincipal)
         {
             result.Add((GroupPrincipal)p);
         }
      }
   }

   return result;
}

and that's all there is! You now have a result (a list) of authorization groups that user belongs to - iterate over them, print out their names or whatever you need to do.

Update: In order to access certain properties, which are not surfaced on the UserPrincipal object, you need to dig into the underlying DirectoryEntry:

public string GetDepartment(Principal principal)
{
    string result = string.Empty;

    DirectoryEntry de = (principal.GetUnderlyingObject() as DirectoryEntry);

    if (de != null)
    {
       if (de.Properties.Contains("department"))
       {
          result = de.Properties["department"][0].ToString();
       }
    }

    return result;
}

Update #2: seems shouldn't be too hard to put these two snippets of code together.... but ok - here it goes:

public string GetDepartment(string username)
{
    string result = string.Empty;

    // if you do repeated domain access, you might want to do this *once* outside this method, 
    // and pass it in as a second parameter!
    PrincipalContext yourDomain = new PrincipalContext(ContextType.Domain);

    // find the user
    UserPrincipal user = UserPrincipal.FindByIdentity(yourDomain, username);

    // if user is found
    if(user != null)
    {
       // get DirectoryEntry underlying it
       DirectoryEntry de = (user.GetUnderlyingObject() as DirectoryEntry);

       if (de != null)
       {
          if (de.Properties.Contains("department"))
          {
             result = de.Properties["department"][0].ToString();
          }
       }
    }

    return result;
}

Make sure that you don't declare it as a integer, float, string or boolean before. http://php.net/manual/en/function.is-scalar.php

If anyone experiences this problem with an express server, add the following middleware

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  next();
});

This will fail (amongst other cases) when the target mailserver uses greylisting.

Greylisting: SMTP server refuses delivery the first time a previously unknown client connects, allows next time(s); this keeps some percentage of spambots out, while allowing legitimate use - as it is expected that a legitimate mail sender will retry, which is what normal mail transfer agents will do.

However, if your code only checks on the server once, a server with greylisting will deny delivery (as your client is connecting for the first time); unless you check again in a little while, you may be incorrectly rejecting valid e-mail addresses.

You can also download psftp.exe from:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

When you run it you type:

open "server name"

Then:

put "file name"

(Type help to get a full list of commands.)

You can also type get <file name> to download files from a remote machine to the local machine.

You can use guide=FALSE in scale_..._...() to suppress legend.

For your example you should use scale_colour_continuous() because length is continuous variable (not discrete).

(p3 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
   scale_colour_continuous(guide = FALSE) +
   geom_point()
)

Or using function guides() you should set FALSE for that element/aesthetic that you don't want to appear as legend, for example, fill, shape, colour.

p0 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
  geom_point()    
p0+guides(colour=FALSE)

UPDATE

Both provided solutions work in new ggplot2 version 2.0.0 but movies dataset is no longer present in this library. Instead you have to use new package ggplot2movies to check those solutions.

library(ggplot2movies)
data(movies)
mov <- subset(movies, length != "")

I'm using:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        const string DEFAULT_NAMESPACE = "http://www.something.org/schema";
        var serializer = new XmlSerializer(typeof(Person), DEFAULT_NAMESPACE);
        var namespaces = new XmlSerializerNamespaces();
        namespaces.Add("", DEFAULT_NAMESPACE);

        using (var stream = new MemoryStream())
        {
            var someone = new Person
            {
                FirstName = "Donald",
                LastName = "Duck"
            };
            serializer.Serialize(stream, someone, namespaces);
            stream.Position = 0;
            using (var reader = new StreamReader(stream))
            {
                Console.WriteLine(reader.ReadToEnd());
            }
        }
    }
}

To get the following XML:

<?xml version="1.0"?>
<Person xmlns="http://www.something.org/schema">
  <FirstName>Donald</FirstName>
  <LastName>Duck</LastName>
</Person>

If you don't want the namespace, just set DEFAULT_NAMESPACE to "".

I created a WSGI middleware that stores the raw body from the environ['wsgi.input'] stream. I saved the value in the WSGI environ so I could access it from request.environ['body_copy'] within my app.

This isn't necessary in Werkzeug or Flask, as request.get_data() will get the raw data regardless of content type, but with better handling of HTTP and WSGI behavior.

This reads the entire body into memory, which will be an issue if for example a large file is posted. This won't read anything if the Content-Length header is missing, so it won't handle streaming requests.

from io import BytesIO

class WSGICopyBody(object):
    def __init__(self, application):
        self.application = application

    def __call__(self, environ, start_response):
        length = int(environ.get('CONTENT_LENGTH') or 0)
        body = environ['wsgi.input'].read(length)
        environ['body_copy'] = body
        # replace the stream since it was exhausted by read()
        environ['wsgi.input'] = BytesIO(body)
        return self.application(environ, start_response)

app.wsgi_app = WSGICopyBody(app.wsgi_app)

request.environ['body_copy']

You can use yahoo to get daily data (a much more managable dataset) but you have to structure the urls. See this link. You are not making lots of little requests you are making a fewer large requests. Lot of free software uses this so they shouldn't shut you down.

EDIT: This guy does it, maybe you can have a look at the calls his software makes.

You can see the errors after stopping debbuging by choosing the option to display ASP.NET Core Web Server output in the output window. In my case I was pointing to a different templateUrl.

If it gets into the selinux arena you've got a much more complicated issue. It's not a good idea to remove the selinux protection but to embrace it and use the tools that were designed to manage it.

If you are serving content out of /var/www/abc, you can verify the selinux permissions with a Z appended to the normal ls -l command. i.e. ls -laZ will give the selinux context.

To add a directory to be served by selinux you can use the semanage command like this. This will change the label on /var/www/abc to httpd_sys_content_t

semanage fcontext -a -t httpd_sys_content_t /var/www/abc

this will update the label for /var/www/abc

restorecon /var/www/abc 

This answer was taken from unixmen and modified to fit this question. I had been searching for this answer for a while and finally found it so felt like I needed to share somewhere. Hope it helps someone.

just add your .jar file in applet tag as an attribute as shown below:

<applet
    code="file.class"
    archive="file.jar"
    height=550 
    width=1100>         
</applet>

You can use the CSS3 zoom function, but I have not tested it yet with jQuery. Will try now and let you know. UPDATE: tested it, works but it's fun

If you simply need to get the basic snapshot of the files + folders. Follow these baby steps:

• Press Windows + R
• Press Enter
• Type cmd
• Press Enter
• Type dir -s
• Press Enter

It worked with me like the following....

Lib1.js

//Any other private code here 

// Code you want to export
exports.function1 = function(params) {.......};
exports.function2 = function(params) {.......};

// Again any private code

now in the Main.js file you need to include Lib1.js

var mylib = requires('lib1.js');
mylib.function1(params);
mylib.function2(params);

Please remember to put the Lib1.js in node_modules folder.

Try to get your archive using wget, I had the same issue when I was downloading archive through browser. Than I just copy archive link and in terminal use the command:

wget http://PATH_TO_ARCHIVE

Here's another option:

df.replace(to_replace=[None], value=np.nan, inplace=True)

You can also do it in a three line method:

public static int gcd(int x, int y){
  return (y == 0) ? x : gcd(y, x % y);
}

Here, if y = 0, x is returned. Otherwise, the gcd method is called again, with different parameter values.

The Watcher method fires on every character input. So, I built this code based on onFocusChange method:

public static boolean comS(String s1,String s2){
    if (s1.length()==s2.length()){
        int l=s1.length();
        for (int i=0;i<l;i++){
            if (s1.charAt(i)!=s2.charAt(i))return false;
        }
        return true;
    }
    return false;
}

public void onChange(final EditText EdTe, final Runnable FRun){
    class finalS{String s="";}
    final finalS dat=new finalS();  
    EdTe.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {dat.s=""+EdTe.getText();}
            else if (!comS(dat.s,""+EdTe.getText())){(new Handler()).post(FRun);}       
        }
    });
}

To using it, just call like this:

onChange(YourEditText, new Runnable(){public void run(){
    // V  V    YOUR WORK HERE

    }}
);

You can ignore the comS function by replace the !comS(dat.s,""+EdTe.getText()) with !equal function. However the equal function itself some time work not correctly in run time.

The onChange listener will remember old data of EditText when user focus typing, and then compare the new data when user lose focus or jump to other input. If comparing old String not same new String, it fires the work.

If you only have 1 EditText, then u will need to make a ClearFocus function by making an Ultimate Secret Transparent Micro EditText outside the windows and request focus to it, then hide the keyboard via Import Method Manager.

I'm not sure about C++, but you can definitely code iPhone applications in C#, using a product called MonoTouch.

You can see this post for detailed discussion on MonoTouch Vs Obj-C: How to decide between MonoTouch and Objective-C?

The thread is old, but maybe someone is still interested. The shortest form I found is further improvement on the example from ?lex and bmargulies. The execution tag will look like:

<execution>
    <id>TheNameOfTheRelevantExecution</id>
    <phase/>
</execution>

2 points I want to highlight:

1. phase is set to nothing, which looks less hacky than 'none', though still a hack.
2. id must be the same as execution you want to override. If you don't specify id for execution, Maven will do it implicitly (in a way not expected intuitively by you).

After posting found it is already in stackoverflow: In a Maven multi-module project, how can I disable a plugin in one child?

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

You're almost all the way there.

Your first few lines, comparing the last name, are right on track. The compareTo() method on string will return a negative number for a string in alphabetical order before, and a positive number for one in alphabetical order after.

Now, you just need to do the same thing for your first name and score.

In other words, if Last Name 1 == Last Name 2, go on a check your first name next. If the first name is the same, check your score next. (Think about nesting your if/then blocks.)

The plug offered by Vinny is really close, but I found and fixed a couple of small issues.

1. It greedily targeted td elements beyond just the children of the row being hidden. This would have been kind of ok if it had then sought out those children when showing the row. While it got close, they all ended up with "display: none" on them, rendering them hidden.
2. It didn't target child th elements at all.

3. For table cells with lots of content (like a nested table with lots of rows), calling slideRow('up'), regardless of the slideSpeed value provided, it'd collapse the view of the row as soon as the padding animation was done. I fixed it so the padding animation doesn't trigger until the slideUp() method on the wrapping is done.

   (function($){
       var sR = {
           defaults: {

You are using wrong JSON. In this case you should use JSON that looks like this:

["orange", "apple"]

If you have to accept JSON in that form :

{"fruits":["apple","orange"]}

You'll have to create wrapper object:

public class FruitWrapper{

    List<String> fruits;

    //getter
    //setter
}

and then your controller method should look like this:

@RequestMapping(value = "/saveFruits", method = RequestMethod.POST, 
    consumes = "application/json")
@ResponseBody
public ResultObject saveFruits(@RequestBody FruitWrapper fruits){
...
}

Try using this: On the command line, in your home directory, create a directory for global installations:

mkdir ~/.npm-global

Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'

In your preferred text editor, open or create a ~/.profile file and add this line:

export PATH=~/.npm-global/bin:$PATH

On the command line, update your system variables:

source ~/.profile

Now use npm install it should work.

To say it differently: When you insert a key-value-pair into a HashMap where the key already exists (in a sense hashvalue() gives the same value und equal() is true, but the two objects can still differ in several ways), the key isn't replaced but the value is overwritten. The key is just used to get the hashvalue() and find the value in the table with it. Since HashSet uses the keys of a HashMap and sets arbitrary values which don't really matter (to the user) as a result the Elements of the Set aren't replaced either.

Your missing a ' after night. right here getElementById('Night

Explaining with Pictures :

Data-Binding needs a mapping

The reference in the scope is not exactly the reference in the template. When you data-bind two objects, you need a third one that listen to the first and modify the other.

Here, when you modify the <input>, you touch the data-ref3. And the classic data-bind mecanism will change data-ref4. So how the other {{data}} expressions will move ?

Events leads to $digest()

Angular maintains a oldValue and newValue of every binding. And after every Angular event, the famous $digest() loop will check the WatchList to see if something changed. These Angular events are ng-click, ng-change, $http completed ... The $digest() will loop as long as any oldValue differs from the newValue.

In the previous picture, it will notice that data-ref1 and data-ref2 has changed.

Conclusions

It's a little like the Egg and Chicken. You never know who starts, but hopefully it works most of the time as expected.

The other point is that you can understand easily the impact deep of a simple binding on the memory and the CPU. Hopefully Desktops are fat enough to handle this. Mobile phones are not that strong.

Here's a solution:

<style>
#firstDiv {
    position:absolute; top:100%;
}
#wrapper {
    position:relative; 
}

But I suspect you have some content that follows the wrapper div...

This is basically the same solution as @andy-wilkinson provided, but as of Spring Boot 1.0 the customize(...) method has a ConfigurableEmbeddedServletContainer parameter.

Another thing that is worth mentioning is that Tomcat only compresses content types of text/html, text/xml and text/plain by default. Below is an example that supports compression of application/json as well:

@Bean
public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer servletContainer) {
            ((TomcatEmbeddedServletContainerFactory) servletContainer).addConnectorCustomizers(
                    new TomcatConnectorCustomizer() {
                        @Override
                        public void customize(Connector connector) {
                            AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
                            httpProtocol.setCompression("on");
                            httpProtocol.setCompressionMinSize(256);
                            String mimeTypes = httpProtocol.getCompressableMimeTypes();
                            String mimeTypesWithJson = mimeTypes + "," + MediaType.APPLICATION_JSON_VALUE;
                            httpProtocol.setCompressableMimeTypes(mimeTypesWithJson);
                        }
                    }
            );
        }
    };
}

If you want to reset your table, you can do

truncate table TableName

truncate needs privileges, and you can't use it if your table has dependents (another tables that have FK of your table,

At first install necessary PDO parts by running the command

`sudo apt-get install php*-mysql` 

where * is a version name of php like 5.6, 7.0, 7.1, 7.2

After installation you need to mention these two statements

extension=pdo.so
extension=pdo_mysql.so

in your .ini file (uncomment if it is already there) and restart server by command

sudo service apache2 restart

Few hints to handle such error/exception for Android Apps:

1. Activities & Application have methods like:

   • onLowMemory
   • onTrimMemory Handle these methods to watch on memory usage.

2. tag in Manifest can have attribute 'largeHeap' set to TRUE, which requests more heap for App sandbox.

3. Managing in-memory caching & disk caching:

   • Images and other data could have been cached in-memory while app running, (locally in activities/fragment and globally); should be managed or removed.

4. Use of WeakReference, SoftReference of Java instance creation , specifically to files.

5. If so many images, use proper library/data structure which can manage memory, use samling of images loaded, handle disk-caching.

6. Handle OutOfMemory exception

7. Follow best practices for coding

   • Leaking of memory (Don't hold everything with strong reference)

8. Minimize activity stack e.g. number of activities in stack (Don't hold everything on context/activty)

   • Context makes sense, those data/instances not required out of scope (activity and fragments), hold them into appropriate context instead global reference-holding.

9. Minimize the use of statics, many more singletons.

10. Take care of OS basic memory fundametals

    • Memory fragmentation issues

11. Involk GC.Collect() manually sometimes when you are sure that in-memory caching no more needed.

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

http://schacon.github.com/git/gitignore.html

*.json
!spec/*.json

You can declare the macro NULL. Add that after your #includes:

#define NULL 0

or

#ifndef NULL
#define NULL 0
#endif

No ";" at the end of the instructions...

The # means that it matches the id of an element. The . signifies the class name:

<div id="myRedText">This will be red.</div>
<div class="blueText">this will be blue.</div>


#myRedText {
    color: red;
}
.blueText {
    color: blue;
}

Note that in a HTML document, the id attribute must be unique, so if you have more than one element needing a specific style, you should use a class name.

Strictly in reference to prefacing "transpose", by the book, either one will work; i.e., application.transpose() OR worksheetfunction.transpose(), and by experience, if you really like typing, application.WorksheetFunction.Transpose() will work also-

1. Check the latest Jest (v 0.22): https://github.com/facebook/jest

2. The Facebook team adds the Istanbul code coverage output as part of the coverage report and you can use it directly.

3. After executing Jest, you can get a coverage report in the console and under the root folder set by Jest, you will find the coverage report in JSON and HTML format.

4. FYI, if you install from npm, you might not get the latest version; so try the GitHub first and make sure the coverage is what you need.

Actually whether there are digits or not is irrelevant. The . (dot) is forbidden if you want to cast to int. Dot can't - logically - be part of Integer definition, so even:

select cast ('7.0' as int)
select cast ('7.' as int)

will fail but both are fine for floats.

You can of course use a loop, or you can insert them in a single statement, e.g.

Insert into db
(names,email,password) 
Values
('abc','def','mypassword')
,('ghi','jkl','mypassword2')
,('mno','pqr','mypassword3')

It really depends where you're getting your data from.

If you use a loop, wrapping it in a transaction will make it a bit faster.

UPDATE

What if i want to insert unique names?

If you want to insert unique names, then you need to generate data with unique names. One way to do this is to use Visual Studio to generate test data.

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

In my case, Dropbox overlays were starting with a " (quoted identifier) in the registry. I deleted all the " prefixes and restarted explorer.exe.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers

Edit: I installed Windows 10 and this solution didn't work for me. So I just went to the same registry location and deleted all Google and SkyDrive records and restarted explorer.exe.

Second edit: After installing TortoiseGit it fixed everything without any customisation.

Here's a simple function I made. It accepts a string CSV line and returns an array of fields:

It works well with Excel generated CSV files, and many other variations.

    public static string[] ParseCsvRow(string r)
    {

        string[] c;
        string t;
        List<string> resp = new List<string>();
        bool cont = false;
        string cs = "";

        c = r.Split(new char[] { ',' }, StringSplitOptions.None);

        foreach (string y in c)
        {
            string x = y;


            if (cont)
            {
                // End of field
                if (x.EndsWith("\""))
                {
                    cs += "," + x.Substring(0, x.Length - 1);
                    resp.Add(cs);
                    cs = "";
                    cont = false;
                    continue;

                }
                else
                {
                    // Field still not ended
                    cs += "," + x;
                    continue;
                }
            }

            // Fully encapsulated with no comma within
            if (x.StartsWith("\"") && x.EndsWith("\""))
            {
                if ((x.EndsWith("\"\"") && !x.EndsWith("\"\"\"")) && x != "\"\"")
                {
                    cont = true;
                    cs = x;
                    continue;
                }

                resp.Add(x.Substring(1, x.Length - 2));
                continue;
            }

            // Start of encapsulation but comma has split it into at least next field
            if (x.StartsWith("\"") && !x.EndsWith("\""))
            {
                cont = true;
                cs += x.Substring(1);
                continue;
            }

            // Non encapsulated complete field
            resp.Add(x);

        }

        return resp.ToArray();

    }

@IronMensan's format method answer is the way to go. But in the interest of answering your question about ljust:

>>> def printit():
...     print 'Location: 10-10-10-10'.ljust(40) + 'Revision: 1'
...     print 'District: Tower'.ljust(40) + 'Date: May 16, 2012'
...     print 'User: LOD'.ljust(40) + 'Time: 10:15'
...
>>> printit()
Location: 10-10-10-10                   Revision: 1
District: Tower                         Date: May 16, 2012
User: LOD                               Time: 10:15

Edit to note this method doesn't require you to know how long your strings are. .format() may also, but I'm not familiar enough with it to say.

>>> uname='LOD'
>>> 'User: {}'.format(uname).ljust(40) + 'Time: 10:15'
'User: LOD                               Time: 10:15'
>>> uname='Tiddlywinks'
>>> 'User: {}'.format(uname).ljust(40) + 'Time: 10:15'
'User: Tiddlywinks                       Time: 10:15'

This is pretty much as close as you'll get if you want to use the ActionBar APIs. I'm not sure you can place a colorstrip above the ActionBar without doing some weird Window hacking, it's not worth the trouble. As far as changing the MenuItems goes, you can make those tighter via a style. It would be something like this, but I haven't tested it.

<style name="MyTheme" parent="android:Theme.Holo.Light">
    <item name="actionButtonStyle">@style/MyActionButtonStyle</item>
</style>

<style name="MyActionButtonStyle" parent="Widget.ActionButton">
    <item name="android:minWidth">28dip</item>
</style>

Here's how to inflate and add the custom layout to your ActionBar.

    // Inflate your custom layout
    final ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(
            R.layout.action_bar,
            null);

    // Set up your ActionBar
    final ActionBar actionBar = getActionBar();
    actionBar.setDisplayShowHomeEnabled(false);
    actionBar.setDisplayShowTitleEnabled(false);
    actionBar.setDisplayShowCustomEnabled(true);
    actionBar.setCustomView(actionBarLayout);

    // You customization
    final int actionBarColor = getResources().getColor(R.color.action_bar);
    actionBar.setBackgroundDrawable(new ColorDrawable(actionBarColor));

    final Button actionBarTitle = (Button) findViewById(R.id.action_bar_title);
    actionBarTitle.setText("Index(2)");

    final Button actionBarSent = (Button) findViewById(R.id.action_bar_sent);
    actionBarSent.setText("Sent");

    final Button actionBarStaff = (Button) findViewById(R.id.action_bar_staff);
    actionBarStaff.setText("Staff");

    final Button actionBarLocations = (Button) findViewById(R.id.action_bar_locations);
    actionBarLocations.setText("HIPPA Locations");

Here's the custom layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:enabled="false"
    android:orientation="horizontal"
    android:paddingEnd="8dip" >

    <Button
        android:id="@+id/action_bar_title"
        style="@style/ActionBarButtonWhite" />

    <Button
        android:id="@+id/action_bar_sent"
        style="@style/ActionBarButtonOffWhite" />

    <Button
        android:id="@+id/action_bar_staff"
        style="@style/ActionBarButtonOffWhite" />

    <Button
        android:id="@+id/action_bar_locations"
        style="@style/ActionBarButtonOffWhite" />

</LinearLayout>

Here's the color strip layout: To use it, just use merge in whatever layout you inflate in setContentView.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/colorstrip"
    android:background="@android:color/holo_blue_dark" />

Here are the Button styles:

<style name="ActionBarButton">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:background">@null</item>
    <item name="android:ellipsize">end</item>
    <item name="android:singleLine">true</item>
    <item name="android:textSize">@dimen/text_size_small</item>
</style>

<style name="ActionBarButtonWhite" parent="@style/ActionBarButton">
    <item name="android:textColor">@color/white</item>
</style>

<style name="ActionBarButtonOffWhite" parent="@style/ActionBarButton">
    <item name="android:textColor">@color/off_white</item>
</style>

Here are the colors and dimensions I used:

<color name="action_bar">#ff0d0d0d</color>
<color name="white">#ffffffff</color>
<color name="off_white">#99ffffff</color>

<!-- Text sizes -->
<dimen name="text_size_small">14.0sp</dimen>
<dimen name="text_size_medium">16.0sp</dimen>

<!-- ActionBar color strip -->
<dimen name="colorstrip">5dp</dimen>

If you want to customize it more than this, you may consider not using the ActionBar at all, but I wouldn't recommend that. You may also consider reading through the Android Design Guidelines to get a better idea on how to design your ActionBar.

If you choose to forgo the ActionBar and use your own layout instead, you should be sure to add action-able Toasts when users long press your "MenuItems". This can be easily achieved using this Gist.

As others have pointed out, the % (remainder) operator is not the same as the mathematical mod modulus operation/function.

mod vs %

The x mod n function maps x to n in the range of [0,n).
Whereas the x % n operator maps x to n in the range of (-n,n).

In order to have a method to use the mathematical modulus operation and not care about the sign in front of x one can use:

((x % n) + n) % n

Maybe this picture helps understand it better (I had a hard time wrapping my head around this first)

An enum is implictly final, with a private constructors, all its values are of the same type or a sub-type, you can obtain all its values using values(), gets its name() or ordinal() value or you can look up an enum by number or name.

You can also define subclasses (even though notionally final, something you can't do any other way)

enum Runner implements Runnable {
    HI {
       public void run() {
           System.out.println("Hello");
       }
    }, BYE {
       public void run() {
           System.out.println("Sayonara");
       }
       public String toString() {
           return "good-bye";
       }
    }
 }

 class MYRunner extends Runner // won't compile.

well no need of passing the context and doing all that...simply do this

Context context = parent.getContext();

Edit: where parent is the ViewGroup

You can use : Query grouping allows you to create groups of WHERE clauses by enclosing them in parentheses. This will allow you to create queries with complex WHERE clauses. Nested groups are supported. Example:

$this->db->select('*')->from('my_table')
        ->group_start()
                ->where('a', 'a')
                ->or_group_start()
                        ->where('b', 'b')
                        ->where('c', 'c')
                ->group_end()
        ->group_end()
        ->where('d', 'd')
->get();

My situation was that I did not have a main function.

Since you add .. after cmake, it will jump up and up (just like cd ..) in the directory. But if you want to run cmake under the same folder with CMakeLists.txt, please use . instead of ...

'1' >>> Catchall for general errors

'2' >>> Misuse of shell builtins (according to Bash documentation)

'126'>>> Command invoked cannot execute

'127'>>>"command not found"

'128'>>> Invalid argument to exit

'128+n'>>>Fatal error signal "n"

'130'>>> Script terminated by Control-C

'255'>>>Exit status out of range

This is for bash. However, for other applications, there are different exit codes.

Most likely, cron is running in a very sparse environment. Check the environment variables cron is using by appending a dummy job which dumps env to a file like this:

* * * * * env > env_dump.txt

Compare that with the output of env in a normal shell session.

You can prepend your own environment variables to the local crontab by defining them at the top of your crontab.

Here's a quick fix to prepend $PATH to the current crontab:

# echo PATH=$PATH > tmp.cron
# echo >> tmp.cron
# crontab -l >> tmp.cron
# crontab tmp.cron

The resulting crontab will look similar to chrissygormley's answer, with PATH defined before the crontab rules.

This works in the note-taking Joplin:

<span style="color:red">text in red</span>

This works:

df['date'].dt.year

Now:

df['year'] = df['date'].dt.year
df['month'] = df['date'].dt.month

gives this data frame:

        date  Count  year  month
0 2010-06-30    525  2010      6
1 2010-07-30    136  2010      7
2 2010-08-31    125  2010      8
3 2010-09-30     84  2010      9
4 2010-10-29   4469  2010     10

With the update of Android Studio to 1.0, the NDK toolchain support improved immensely (note: please read my updates at the bottom of this post to see usage with the new experimental Gradle plugin and Android Studio 1.5).

Android Studio and the NDK are integrated well enough so that you just need to create an ndk{} block in your module's build.gradle, and set your source files into the (module)/src/main/jni directory - and you're done!

No more ndk-build from the command line.

I've written all about it in my blog post here: http://www.sureshjoshi.com/mobile/android-ndk-in-android-studio-with-swig/

The salient points are:

There are two things you need to know here. By default, if you have external libs that you want loaded into the Android application, they are looked for in the (module)/src/main/jniLibs by default. You can change this by using setting sourceSets.main.jniLibs.srcDirs in your module’s build.gradle. You’ll need a subdirectory with libraries for each architecture you’re targeting (e.g. x86, arm, mips, arm64-v8a, etc…)

The code you want to be compiled by default by the NDK toolchain will be located in (module)/src/main/jni and similarly to above, you can change it by setting sourceSets.main.jni.srcDirs in your module’s build.gradle

and put this into your module's build.gradle:

ndk {
  moduleName "SeePlusPlus" // Name of C++ module (i.e. libSeePlusPlus)
  cFlags "-std=c++11 -fexceptions" // Add provisions to allow C++11 functionality
  stl "gnustl_shared" // Which STL library to use: gnustl or stlport
}

That's the process of compiling your C++ code, from there you need to load it, and create wrappers - but judging from your question, you already know how to do all that, so I won't re-hash.

Also, I've placed a Github repo of this example here: http://github.com/sureshjoshi/android-ndk-swig-example

UPDATE: June 14, 2015

When Android Studio 1.3 comes out, there should be better support for C++ through the JetBrains CLion plugin. I'm currently under the assumption that this will allow Java and C++ development from within Android Studio; however I think we'll still need to use the Gradle NDK section as I've stated above. Additionally, I think there will still be the need to write Java<->C++ wrapper files, unless CLion will do those automatically.

UPDATE: January 5, 2016

I have updated my blog and Github repo (in the develop branch) to use Android Studio 1.5 with the latest experimental Gradle plugin (0.6.0-alpha3).

http://www.sureshjoshi.com/mobile/android-ndk-in-android-studio-with-swig/ http://github.com/sureshjoshi/android-ndk-swig-example

The Gradle build for the NDK section now looks like this:

android.ndk {
    moduleName = "SeePlusPlus" // Name of C++ module (i.e. libSeePlusPlus)
    cppFlags.add("-std=c++11") // Add provisions to allow C++11 functionality
    cppFlags.add("-fexceptions")
    stl = "gnustl_shared" // Which STL library to use: gnustl or stlport
}

Also, quite awesomely, Android Studio has auto-complete for C++-Java generated wrappers using the 'native' keyword:

However, it's not completely rosy... If you're using SWIG to wrap a library to auto-generate code, and then try to use the native keyword auto-generation, it will put the code in the wrong place in your Swig _wrap.cxx file... So you need to move it into the "extern C" block:

UPDATE: October 15, 2017

I'd be remiss if I didn't mention that Android Studio 2.2 onwards has essentially 'native' (no pun) support for the NDK toolchain via Gradle and CMake. Now, when you create a new project, just select C++ support and you're good to go.

You'll still need to generate your own JNI layer code, or use the SWIG technique I've mentioned above, but the scaffolding of a C++ in Android project is trivial now.

Changes in the CMakeLists file (which is where you place your C++ source files) will be picked up by Android Studio, and it'll automatically re-compile any associated libraries.

In my case, while playing video, I needed to call a function everytime currentTime of video updates. So I used timeupdate event of video and I came to know that it was fired at least 4 times a second (depends on the browser you use, see this). So I changed it to call a function every second like this:

var currentIntTime = 0;

var someFunction = function() {
    currentIntTime++;
    // Do something here
} 
vidEl.on('timeupdate', function(){
    if(parseInt(vidEl.currentTime) > currentIntTime) {
        someFunction();
    }
});

This reduces calls to someFunc by at least 1/3 and it may help your browser to behave normally. It did for me !!!

I had this problem when I reopened a project (which was developed on XCode 3.something on Leopard) after upgrading to Snow Leopard and XCode 3.2. Curious enough, it only affected some kinds of builds (emulator builds went fine, device ones gave me the error). And I have libxml2 at /usr/include, and it indeed contains libxml/tree.h.

Even the magic "Clean" did not work, but "Empty Caches..." under the "XCode" menu (between the Apple logo and File) did the trick (was that menu there in previous versions?). Beats me the reason, but after a clean there were no more complaints regarding libxml/tree.h

Nesting a stackpanel will cause the textbox to wrap properly:

<Viewbox Margin="120,0,120,0">
    <StackPanel Orientation="Vertical" Width="400">
        <TextBlock x:Name="subHeaderText" 
                   FontSize="20" 
                   TextWrapping="Wrap" 
                   Foreground="Black"
                   Text="Lorem ipsum dolor, lorem isum dolor,Lorem ipsum dolor sit amet, lorem ipsum dolor sit amet " />
    </StackPanel>
</Viewbox>

The recommended approach is to use fill constructor to initialize a two-dimensional vector with a given default value :

std::vector<std::vector<int>> fog(M, std::vector<int>(N, default_value));

where, M and N are dimensions for your 2D vector.

Try to add the code in wp-config.php:

define('FS_METHOD', 'direct');

I found a way to cover the shadow with ":after", here is my code:

#div:after {
    content:"";
    position:absolute;
    width:5px;
    background:#fff;
    height:38px;
    top:1px;
    right:-5px;
}

u should add a theme to ur all activities (u should add theme for all application in ur <application> in ur manifest) but if u have set different theme to ur activity u can use :

 android:theme="@style/Theme.AppCompat"

or each kind of AppCompat theme!

Not removing but creating a new List without that element with LINQ:

// remove
users = users.Where(u => u.userId != 123).ToList();

// new list
var modified = users.Where(u => u.userId == 123).ToList();

To crop retina images while keeping the same scale and orientation, use the following method in a UIImage category (iOS 4.0 and above):

- (UIImage *)crop:(CGRect)rect {
    if (self.scale > 1.0f) {
        rect = CGRectMake(rect.origin.x * self.scale,
                          rect.origin.y * self.scale,
                          rect.size.width * self.scale,
                          rect.size.height * self.scale);
    }

    CGImageRef imageRef = CGImageCreateWithImageInRect(self.CGImage, rect);
    UIImage *result = [UIImage imageWithCGImage:imageRef scale:self.scale orientation:self.imageOrientation];
    CGImageRelease(imageRef);
    return result;
}

You can achieve that by using positioning.

Try

position: absolute;

to get the 100% height.

Check whether a String contains at least one white space character:

public static boolean containsWhiteSpace(final String testCode){
    if(testCode != null){
        for(int i = 0; i < testCode.length(); i++){
            if(Character.isWhitespace(testCode.charAt(i))){
                return true;
            }
        }
    }
    return false;
}

Reference:

• Character.isWhitespace(char)

Using the Guava library, it's much simpler:

return CharMatcher.WHITESPACE.matchesAnyOf(testCode);

CharMatcher.WHITESPACE is also a lot more thorough when it comes to Unicode support.

The 'a' parameter signifies append mode. If you don't want to use with open each time, you can easily write a function to do it for you:

def append(txt='\nFunction Successfully Executed', file):
    with open(file, 'a') as f:
        f.write(txt)

If you want to write somewhere else other than the end, you can use 'r+'^†:

import os

with open(file, 'r+') as f:
    f.seek(0, os.SEEK_END)
    f.write("text to add")

Finally, the 'w+' parameter grants even more freedom. Specifically, it allows you to create the file if it doesn't exist, as well as empty the contents of a file that currently exists.

^† Credit for this function goes to @Primusa

It's called models.Model and not models.model (case sensitive). Fix your Poll model like this -

class Poll(models.Model):
    question = models.CharField(max_length=200) 
    pub_date = models.DateTimeField('date published')

you should try with figaspect. It works for me. From the docs:

Create a figure with specified aspect ratio. If arg is a number, use that aspect ratio. > If arg is an array, figaspect will determine the width and height for a figure that would fit array preserving aspect ratio. The figure width, height in inches are returned. Be sure to create an axes with equal with and height, eg

Example usage:

  # make a figure twice as tall as it is wide
  w, h = figaspect(2.)
  fig = Figure(figsize=(w,h))
  ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
  ax.imshow(A, **kwargs)

  # make a figure with the proper aspect for an array
  A = rand(5,3)
  w, h = figaspect(A)
  fig = Figure(figsize=(w,h))
  ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
  ax.imshow(A, **kwargs)

Edit: I am not sure of what you are looking for. The above code changes the canvas (the plot size). If you want to change the size of the matplotlib window, of the figure, then use:

In [68]: f = figure(figsize=(5,1))

this does produce a window of 5x1 (wxh).

You can also use AWK which can give you more flexibility to handle the file

awk '{ print "chmod 755 "$0"" | "/bin/sh"}' file.txt

if your file has a field separator like:

field1,field2,field3

To get only the first field you do

awk -F, '{ print "chmod 755 "$1"" | "/bin/sh"}' file.txt

For SQL Server 2008, I would imagine the procedure is similar...?

• open SQL Server Management Studio
• log in to a SQL Server instance, right click on "Databases", select "Restore Database"
• wizard appears, you want "from device" which allows you to select a .bak file

If the problem occurs after multi touch you can disable multi touch with

android:splitMotionEvents="false" 

in layout file.

In your httpd.conf make sure you have:

Listen *:80

And if you are using VirtualHosts then set them as given below:

NameVirtualHost *
<VirtualHost *>
   ...
</VirtualHost>

Do git status, this will show you what files have changed. Since you stated that you don't want to keep the changes you can do git checkout -- <file name> or git reset --hard to get rid of the changes.

For the most part, git will tell you what to do about changes. For example, your error message said to git stash your changes. This would be if you wanted to keep them. After pulling, you would then do git stash pop and your changes would be reapplied.

git status also has how to get rid of changes depending on if the file is staged for commit or not.

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

Now Update word-wrap is replace by :

overflow-wrap:break-word;

Compatible old navigator and css 3 it's good alternative !

it's evolution of word-wrap ( since 2012... )

See more information : https://www.w3.org/TR/css-text-3/#overflow-wrap

See compatibility full : http://caniuse.com/#search=overflow-wrap

I found that simply setting the line-height and height to the same pixel quantity produced the most consistent result. By "most consistent" I mean optimally consistent but of course it is not 100% "pixel-perfect" across browsers. Additionally I found that Firefox (v. 17.x) tends to crowd the option text to the right against the drop-down arrow; I alleviated this with a small amount of padding-right set on the OPTION element only. This setting does not affect appearance in IE 7-9.

My result:

select, option {
    font-size:10px;
    height:19px;
    line-height: 19px;
    padding:0;
    margin:0;
}

option {
    padding-right:6px; /* Firefox */
}

NOTE -- my SELECT element uses a smaller font, 10px. Obviously you will need to adjust proportions accordingly for your specific UI context.

The command (or the URL in it) to add the github repository as a remote isn't quite correct. If I understand your repository name correctly, it should be;

git remote add demo_app '[email protected]:levelone/demo_app.git'

For MYSQL

ALTER TABLE myTable MODIFY myColumn {DataType} NULL

check $this->upload->initialize($config); this works fine for me

    $new_image_name = "imgName".time() . str_replace(str_split(' ()\\/,:*?"<>|'), '', 
    $_FILES['userfile']['name']);
    $config = array();
    $config['upload_path'] = './uploads/'; 
    $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
    $config['file_name'] = $new_image_name;
    $config['max_size']  = '0';
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|mp4|jpeg';
    $config['file_name'] = url_title("imgsclogo");
    $config['max_size']      = '0';
    $config['overwrite']     = FALSE; 
    $this->upload->initialize($config);
    $this->upload->do_upload();
    $data = $this->upload->data();
}

ArrayList<Customer> custArr = new ArrayList<Customer>();
while(youWantToContinue) {
    //get a customerName
    //get an amount
    custArr.add(new Customer(customerName, amount);
}

For this to work... you'll have to fix your constructor...

Assuming your Customer class has variables called name and sale, your constructor should look like this:

public Customer(String customerName, double amount) {
    name = customerName;
    sale = amount;
}

Change your Store class to something more like this:

public class Store {

    private ArrayList<Customer> custArr;

    public new Store() {
        custArr = new ArrayList<Customer>();
    }

    public void addSale(String customerName, double amount) {
        custArr.add(new Customer(customerName, amount));
    }

    public Customer getSaleAtIndex(int index) {
        return custArr.get(index);
    }

    //or if you want the entire ArrayList:
    public ArrayList getCustArr() {
        return custArr;
    }
}

No need to code a lot... just follow the following steps:

<input id="input_search" type="text" class="fa" placeholder="&#xf002 Search">

Casting is necessary to tell that you are calling a child and not a parent method. So it's ever downward. However if the method is already defined in the parent class and overriden in the child class, you don't any cast. Here an example:

class Parent{
   void method(){ System.out.print("this is the parent"); }
}

class Child extends Parent{
   @override
   void method(){ System.out.print("this is the child"); }
}
...
Parent o = new Child();
o.method();
((Child)o).method();  

The two method call will both print : "this is the child".

Edit:

If you have snap or want to install it, just do:

$ sudo snap install postman

if you don't have it, install it as:

$ sudo apt update
$ sudo apt install snapd

Another way is create an script:

First create this script:

create a file install-postman.sh, inside of it add:

#!/bin/bash
cd /tmp || exit
echo "Downloading Postman ..."
wget -q https://dl.pstmn.io/download/latest/linux?arch=64 -O postman.tar.gz
tar -xzf postman.tar.gz
rm postman.tar.gz

echo "Installing to opt..."
if [ -d "/opt/Postman" ];then
    sudo rm -rf /opt/Postman
fi
sudo mv Postman /opt/Postman

echo "Creating symbolic link..."
if [ -L "/usr/bin/postman" ];then
    sudo rm -f /usr/bin/postman
fi
sudo ln -s /opt/Postman/Postman /usr/bin/postman

echo "Installation completed successfully."
echo "You can use Postman!"

run it in terminal with:

$ sh install-postman.sh

Then create the desktop launcher:

Postman.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Postman
Exec=postman
Icon=/opt/Postman/resources/app/assets/icon.png
Terminal=false
Type=Application
Categories=Development;

Put this file in your desktop if you want (don't forget give to it execution permissions). Double click, and that's it!

If you work with rails and you have the keys in a separate list, you can use the * notation:

keys = [:foo, :bar]
hash1 = {foo: 1, bar:2, baz: 3}
hash2 = hash1.slice(*keys)
=> {foo: 1, bar:2}

As other answers stated, you can also use slice! to modify the hash in place (and return the erased key/values).

Try

//re:*[. ='match']

By adding the external jar into your build path just adds the jar to your package, but it will not be available during runtime.

In order for the jar to be available at runtime, you need to:

• Put the jar under your assets folder
• Include this copy of the jar in your build path
• Go to the export tab on the same popup window
• Check the box against the newly added jar

Try this:

$(".use-address").click(function() {
   $(this).closest('tr').find('td').each(function() {
        var textval = $(this).text(); // this will be the text of each <td>
   });
});

This will find the closest tr (going up through the DOM) of the currently clicked button and then loop each td - you might want to create a string / array with the values.

It depends on what sender address you are talking about. The sender address visble in the recipients mailprogramm is extracted from the "From:" Header. which can probably easily be set from your program.

If you are talking about the SMTP envelope sender address, you can pass the -f argument to the sendmail binary. Depending on the server configuration you may not be allowed to do that with the apache user.

from the sendmail manpage :

   -f <address>
                 This  option  sets  the  address  of the envelope sender of a
                 locally-generated message (also known as  the  return  path).
                 The  option  can normally be used only by a trusted user, but
                 untrusted_set_sender can be set to allow untrusted  users  to
                 use it. [...]

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

After searching for an hour or two ,I've found a simple solution below.

const date = new Date(`${date from client} GMT`);

inside double ticks, there is a date from client side plust GMT.

I'm first time commenting, constructive criticism will be welcomed.

Add the "extern" keyword to the function definitions in point.h

The simplest way is just to accept the incoming request, and pull out the variables you want in the Controller:

Route::get('search', ['as' => 'search', 'uses' => 'SearchController@search']);

and then in SearchController@search:

class SearchController extends BaseController {

    public function search()
    {
        $category = Input::get('category', 'default category');
        $term = Input::get('term', false);

        // do things with them...
    }
}

Usefully, you can set defaults in Input::get() in case nothing is passed to your Controller's action.

As joe_archer says, it's not necessary to put these terms into the URL, and it might be better as a POST (in which case you should update your call to Form::open() and also your search route in routes.php - Input::get() remains the same)

You may use the following extension method:

public static class CharExtensions
    {
        public static int CharToInt(this char c)
        {
            if (c < '0' || c > '9')
                throw new ArgumentException("The character should be a number", "c");

            return c - '0';

TypeScript's relation to JavaScript

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript - typescriptlang.org.

JavaScript is a programming language that is developed by EMCA's Technical Committee 39, which is a group of people composed of many different stakeholders. TC39 is a committee hosted by ECMA: an internal standards organization. JavaScript has many different implementations by many different vendors (e.g. Google, Microsoft, Oracle, etc.). The goal of JavaScript is to be the lingua franca of the web.

TypeScript is a superset of the JavaScript language that has a single open-source compiler and is developed mainly by a single vendor: Microsoft. The goal of TypeScript is to help catch mistakes early through a type system and to make JavaScript development more efficient.

Essentially TypeScript achieves its goals in three ways:

1. Support for modern JavaScript features - The JavaScript language (not the runtime) is standardized through the ECMAScript standards. Not all browsers and JavaScript runtimes support all features of all ECMAScript standards (see this overview). TypeScript allows for the use of many of the latest ECMAScript features and translates them to older ECMAScript targets of your choosing (see the list of compile targets under the --target compiler option). This means that you can safely use new features, like modules, lambda functions, classes, the spread operator and destructuring, while remaining backwards compatible with older browsers and JavaScript runtimes.

2. Advanced type system - The type support is not part of the ECMAScript standard and will likely never be due to the interpreted nature instead of compiled nature of JavaScript. The type system of TypeScript is incredibly rich and includes: interfaces, enums, hybrid types, generics, union/intersection types, access modifiers and much more. The official website of TypeScript gives an overview of these features. Typescript's type system is on-par with most other typed languages and in some cases arguably more powerful.

3. Developer tooling support - TypeScript's compiler can run as a background process to support both incremental compilation and IDE integration such that you can more easily navigate, identify problems, inspect possibilities and refactor your codebase.

TypeScript's relation to other JavaScript targeting languages

TypeScript has a unique philosophy compared to other languages that compile to JavaScript. JavaScript code is valid TypeScript code; TypeScript is a superset of JavaScript. You can almost rename your .js files to .ts files and start using TypeScript (see "JavaScript interoperability" below). TypeScript files are compiled to readable JavaScript, so that migration back is possible and understanding the compiled TypeScript is not hard at all. TypeScript builds on the successes of JavaScript while improving on its weaknesses.

On the one hand, you have future proof tools that take modern ECMAScript standards and compile it down to older JavaScript versions with Babel being the most popular one. On the other hand, you have languages that may totally differ from JavaScript which target JavaScript, like CoffeeScript, Clojure, Dart, Elm, Haxe, Scala.js, and a whole host more (see this list). These languages, though they might be better than where JavaScript's future might ever lead, run a greater risk of not finding enough adoption for their futures to be guaranteed. You might also have more trouble finding experienced developers for some of these languages, though the ones you will find can often be more enthusiastic. Interop with JavaScript can also be a bit more involved, since they are farther removed from what JavaScript actually is.

TypeScript sits in between these two extremes, thus balancing the risk. TypeScript is not a risky choice by any standard. It takes very little effort to get used to if you are familiar with JavaScript, since it is not a completely different language, has excellent JavaScript interoperability support and it has seen a lot of adoption recently.

Optionally static typing and type inference

JavaScript is dynamically typed. This means JavaScript does not know what type a variable is until it is actually instantiated at run-time. This also means that it may be too late. TypeScript adds type support to JavaScript and catches type errors during compilation to JavaScript. Bugs that are caused by false assumptions of some variable being of a certain type can be completely eradicated if you play your cards right (how strict you type your code or if you type your code at all is up to you).

TypeScript makes typing a bit easier and a lot less explicit by the usage of type inference. For example: var x = "hello" in TypeScript is the same as var x : string = "hello". The type is simply inferred from its use. Even it you don't explicitly type the types, they are still there to save you from doing something which otherwise would result in a run-time error.

TypeScript is optionally typed by default. For example function divideByTwo(x) { return x / 2 } is a valid function in TypeScript which can be called with any kind of parameter, even though calling it with a string will obviously result in a runtime error. Just like you are used to in JavaScript. This works, because when no type was explicitly assigned and the type could not be inferred, like in the divideByTwo example, TypeScript will implicitly assign the type any. This means the divideByTwo function's type signature automatically becomes function divideByTwo(x : any) : any. There is a compiler flag to disallow this behavior: --noImplicitAny. Enabling this flag gives you a greater degree of safety, but also means you will have to do more typing.

Types have a cost associated with them. First of all, there is a learning curve, and second of all, of course, it will cost you a bit more time to set up a codebase using proper strict typing too. In my experience, these costs are totally worth it on any serious codebase you are sharing with others. A Large Scale Study of Programming Languages and Code Quality in Github suggests that "statically typed languages, in general, are less defect prone than the dynamic types, and that strong typing is better than weak typing in the same regard".

It is interesting to note that this very same paper finds that TypeScript is less error-prone than JavaScript:

For those with positive coefficients we can expect that the language is associated with, ceteris paribus, a greater number of defect fixes. These languages include C, C++, JavaScript, Objective-C, Php, and Python. The languages Clojure, Haskell, Ruby, Scala, and TypeScript, all have negative coefficients implying that these languages are less likely than the average to result in defect fixing commits.

Enhanced IDE support

The development experience with TypeScript is a great improvement over JavaScript. The IDE is informed in real-time by the TypeScript compiler on its rich type information. This gives a couple of major advantages. For example, with TypeScript, you can safely do refactorings like renames across your entire codebase. Through code completion, you can get inline help on whatever functions a library might offer. No more need to remember them or look them up in online references. Compilation errors are reported directly in the IDE with a red squiggly line while you are busy coding. All in all, this allows for a significant gain in productivity compared to working with JavaScript. One can spend more time coding and less time debugging.

There is a wide range of IDEs that have excellent support for TypeScript, like Visual Studio Code, WebStorm, Atom and Sublime.

Strict null checks

Runtime errors of the form cannot read property 'x' of undefined or undefined is not a function are very commonly caused by bugs in JavaScript code. Out of the box TypeScript already reduces the probability of these kinds of errors occurring, since one cannot use a variable that is not known to the TypeScript compiler (with the exception of properties of any typed variables). It is still possible though to mistakenly utilize a variable that is set to undefined. However, with the 2.0 version of TypeScript you can eliminate these kinds of errors all together through the usage of non-nullable types. This works as follows:

With strict null checks enabled (--strictNullChecks compiler flag) the TypeScript compiler will not allow undefined to be assigned to a variable unless you explicitly declare it to be of nullable type. For example, let x : number = undefined will result in a compile error. This fits perfectly with type theory since undefined is not a number. One can define x to be a sum type of number and undefined to correct this: let x : number | undefined = undefined.

Once a type is known to be nullable, meaning it is of a type that can also be of the value null or undefined, the TypeScript compiler can determine through control flow based type analysis whether or not your code can safely use a variable or not. In other words when you check a variable is undefined through for example an if statement the TypeScript compiler will infer that the type in that branch of your code's control flow is not anymore nullable and therefore can safely be used. Here is a simple example:

let x: number | undefined;
if (x !== undefined) x += 1; // this line will compile, because x is checked.
x += 1; // this line will fail compilation, because x might be undefined.

During the build, 2016 conference co-designer of TypeScript Anders Hejlsberg gave a detailed explanation and demonstration of this feature: video (from 44:30 to 56:30).

Compilation

To use TypeScript you need a build process to compile to JavaScript code. The build process generally takes only a couple of seconds depending of course on the size of your project. The TypeScript compiler supports incremental compilation (--watch compiler flag) so that all subsequent changes can be compiled at greater speed.

The TypeScript compiler can inline source map information in the generated .js files or create separate .map files. Source map information can be used by debugging utilities like the Chrome DevTools and other IDE's to relate the lines in the JavaScript to the ones that generated them in the TypeScript. This makes it possible for you to set breakpoints and inspect variables during runtime directly on your TypeScript code. Source map information works pretty well, it was around long before TypeScript, but debugging TypeScript is generally not as great as when using JavaScript directly. Take the this keyword for example. Due to the changed semantics of the this keyword around closures since ES2015, this may actually exists during runtime as a variable called _this (see this answer). This may confuse you during debugging but generally is not a problem if you know about it or inspect the JavaScript code. It should be noted that Babel suffers the exact same kind of issue.

There are a few other tricks the TypeScript compiler can do, like generating intercepting code based on decorators, generating module loading code for different module systems and parsing JSX. However, you will likely require a build tool besides the Typescript compiler. For example, if you want to compress your code you will have to add other tools to your build process to do so.

There are TypeScript compilation plugins available for Webpack, Gulp, Grunt and pretty much any other JavaScript build tool out there. The TypeScript documentation has a section on integrating with build tools covering them all. A linter is also available in case you would like even more build time checking. There are also a great number of seed projects out there that will get you started with TypeScript in combination with a bunch of other technologies like Angular 2, React, Ember, SystemJS, Webpack, Gulp, etc.

JavaScript interoperability

Since TypeScript is so closely related to JavaScript it has great interoperability capabilities, but some extra work is required to work with JavaScript libraries in TypeScript. TypeScript definitions are needed so that the TypeScript compiler understands that function calls like _.groupBy or angular.copy or $.fadeOut are not in fact illegal statements. The definitions for these functions are placed in .d.ts files.

The simplest form a definition can take is to allow an identifier to be used in any way. For example, when using Lodash, a single line definition file declare var _ : any will allow you to call any function you want on _, but then, of course, you are also still able to make mistakes: _.foobar() would be a legal TypeScript call, but is, of course, an illegal call at run-time. If you want proper type support and code completion your definition file needs to to be more exact (see lodash definitions for an example).

Npm modules that come pre-packaged with their own type definitions are automatically understood by the TypeScript compiler (see documentation). For pretty much any other semi-popular JavaScript library that does not include its own definitions somebody out there has already made type definitions available through another npm module. These modules are prefixed with "@types/" and come from a Github repository called DefinitelyTyped.

There is one caveat: the type definitions must match the version of the library you are using at run-time. If they do not, TypeScript might disallow you from calling a function or dereferencing a variable that exists or allow you to call a function or dereference a variable that does not exist, simply because the types do not match the run-time at compile-time. So make sure you load the right version of the type definitions for the right version of the library you are using.

To be honest, there is a slight hassle to this and it may be one of the reasons you do not choose TypeScript, but instead go for something like Babel that does not suffer from having to get type definitions at all. On the other hand, if you know what you are doing you can easily overcome any kind of issues caused by incorrect or missing definition files.

Converting from JavaScript to TypeScript

Any .js file can be renamed to a .ts file and ran through the TypeScript compiler to get syntactically the same JavaScript code as an output (if it was syntactically correct in the first place). Even when the TypeScript compiler gets compilation errors it will still produce a .js file. It can even accept .js files as input with the --allowJs flag. This allows you to start with TypeScript right away. Unfortunately, compilation errors are likely to occur in the beginning. One does need to remember that these are not show-stopping errors like you may be used to with other compilers.

The compilation errors one gets in the beginning when converting a JavaScript project to a TypeScript project are unavoidable by TypeScript's nature. TypeScript checks all code for validity and thus it needs to know about all functions and variables that are used. Thus type definitions need to be in place for all of them otherwise compilation errors are bound to occur. As mentioned in the chapter above, for pretty much any JavaScript framework there are .d.ts files that can easily be acquired with the installation of DefinitelyTyped packages. It might, however, be that you've used some obscure library for which no TypeScript definitions are available or that you've polyfilled some JavaScript primitives. In that case, you must supply type definitions for these bits for the compilation errors to disappear. Just create a .d.ts file and include it in the tsconfig.json's files array, so that it is always considered by the TypeScript compiler. In it declare those bits that TypeScript does not know about as type any. Once you've eliminated all errors you can gradually introduce typing to those parts according to your needs.

Some work on (re)configuring your build pipeline will also be needed to get TypeScript into the build pipeline. As mentioned in the chapter on compilation there are plenty of good resources out there and I encourage you to look for seed projects that use the combination of tools you want to be working with.

The biggest hurdle is the learning curve. I encourage you to play around with a small project at first. Look how it works, how it builds, which files it uses, how it is configured, how it functions in your IDE, how it is structured, which tools it uses, etc. Converting a large JavaScript codebase to TypeScript is doable when you know what you are doing. Read this blog for example on converting 600k lines to typescript in 72 hours). Just make sure you have a good grasp of the language before you make the jump.

Adoption

TypeScript is open-source (Apache 2 licensed, see GitHub) and backed by Microsoft. Anders Hejlsberg, the lead architect of C# is spearheading the project. It's a very active project; the TypeScript team has been releasing a lot of new features in the last few years and a lot of great ones are still planned to come (see the roadmap).

Some facts about adoption and popularity:

• In the 2017 StackOverflow developer survey TypeScript was the most popular JavaScript transpiler (9th place overall) and won third place in the most loved programming language category.
• In the 2018 state of js survey TypeScript was declared as one of the two big winners in the JavaScript flavors category (with ES6 being the other).
• In the 2019 StackOverlow deverloper survey TypeScript rose to the 9th place of most popular languages amongst professional developers, overtaking both C and C++. It again took third place amongst most the most loved languages.

Using the standard mysql.createPool(), connections are lazily created by the pool. If you configure the pool to allow up to 100 connections, but only ever use 5 simultaneously, only 5 connections will be made. However if you configure it for 500 connections and use all 500 they will remain open for the durations of the process, even if they are idle!

This means if your MySQL Server max_connections is 510 your system will only have 10 mySQL connections available until your MySQL Server closes them (depends on what you have set your wait_timeout to) or your application closes! The only way to free them up is to manually close the connections via the pool instance or close the pool.

mysql-connection-pool-manager module was created to fix this issue and automatically scale the number of connections dependant on the load. Inactive connections are closed and idle connection pools are eventually closed if there has not been any activity.

    // Load modules
const PoolManager = require('mysql-connection-pool-manager');

// Options
const options = {
  ...example settings
}

// Initialising the instance
const mySQL = PoolManager(options);

// Accessing mySQL directly
var connection = mySQL.raw.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
});

// Initialising connection
connection.connect();

// Performing query
connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
  if (error) throw error;
  console.log('The solution is: ', results[0].solution);
});

// Ending connection
connection.end();

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

You can use nircmd project here: http://www.nirsoft.net/utils/nircmd.html

Example code:

nircmd win move ititle "cmd.exe" 5 5 10 10
nircmd win setsize ititle "cmd.exe" 30 30 100 200
nircmd cmdwait 1000 win setsize ititle "cmd.exe" 30 30 1000 600

The output looks like this:

Here is one that works better for me (LINQPad version):

DateTime d;
DateTime.TryParseExact(
    "2010-08-20T15:00:00Z",
    @"yyyy-MM-dd\THH:mm:ss\Z",
    CultureInfo.InvariantCulture,
    DateTimeStyles.AssumeUniversal, 
    out d);
d.ToString()

produces

true

There's yet another way to do it using Shared Connections, ie: somebody initiates the connection, using a password, and every subsequent connection will multiplex over the same channel, negating the need for re-authentication. ( And its faster too )

# ~/.ssh/config 
ControlMaster auto
ControlPath ~/.ssh/pool/%r@%h

then you just have to log in, and as long as you are logged in, the bash script will be able to open ssh connections.

You can then stop your script from working when somebody has not already opened the channel by:

ssh ... -o KbdInteractiveAuthentication=no ....

So if someone else stumbles upon this here is a JavaScript solution to this problem:

Step 1: Hook your HTML number input box to an onchange event

myHTMLNumberInput.onchange = setTwoNumberDecimal;

or in the html code if you so prefer

<input type="number" onchange="setTwoNumberDecimal" min="0" max="10" step="0.25" value="0.00" />

Step 2: Write the setTwoDecimalPlace method

function setTwoNumberDecimal(event) {
    this.value = parseFloat(this.value).toFixed(2);
}

By changing the '2' in toFixed you can get more or less decimal places if you so prefer.

Yet another method - create a filter function that returns True for all desired tags:

def my_filter(tag):
    return (tag.name == 'a' and
        tag.parent.name == 'li' and
        'test' in tag.parent['class'])

Then just call find_all with the argument:

for a in soup(my_filter): # or soup.find_all(my_filter)
    print a

Or, create a new table as temp with the extra column, copy the data to this new table while manipulating it as necessary to fill the non-nullable new column, and then swap the table via a two-step name change.

Yes, it is more complicated, but you may need to do it this way if you don't want a big UPDATE on a live table.

I found two solution (both for SSH-Slave)

1. Go to the slave settings

2. Add a new environment variable

3. PATH
4. ${PATH}:${HOME}/.pub-cache/bin:${HOME}/.local/bin

The "${HOME}" part is important. This makes the additional PATH absolute. Relative path did not work for me.

Option II (pipeline-script)

Make sure that you have permissions to run the following commands.

If you check the man page of nginx from a terminal

man nginx

you can find this:

-V             Print the nginx version, compiler version, and configure script parameters.

-v             Print the nginx version.

Then type in terminal

nginx -v
nginx version: nginx/1.14.0

nginx -V
nginx version: nginx/1.14.0
built with OpenSSL 1.1.0g  2 Nov 2017
TLS SNI support enabled

If nginx is not installed in your system man nginx command can not find man page, so make sure you have installed nginx.

You can also find the version using this command:

Use one of the command to find the path of nginx

ps aux | grep nginx
ps -ef | grep nginx

root       883  0.0  0.3  44524  3388 ?        Ss   Dec07   0:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on

Then run from terminal:

/usr/sbin/nginx -v

nginx version: nginx/1.14.0

In PHP and JavaScript, it is a strict equality operator. Which means, it will compare both type and values.

The original ASCII table is encoded on 7 bits therefore it has 128 characters.

Nowadays most readers/editors use an "extended" ASCII table (from ISO 8859-1), which is encoded on 8 bits and enjoys 256 characters (including Á, Ä, Œ, é, è and other characters useful for european languages as well as mathematical glyphs and other symbols).

While UTF-8 uses the same encoding as the basic ASCII table (meaning 0x41 is A in both codes), it does not share the same encoding for the "Latin Extended-A" block. Which sometimes causes weird characters to appear in words like à la carte or piñata.

If None is a valid data value then you need to the variable another way. You could use:

var = object()

This sentinel is suggested by Nick Coghlan.

Stateless means the state of the service doesn’t persist between subsequent requests and response. Each request carries its own user credentials and is individually authenticated. But in stateful each request is known from any prior request. All stateful requests are session-oriented i.e. each request need to know and retain changes made in previous requests.

Banking application is an example of stateful application. Where user first login then make transaction and logs out. If after logout user will try to make the transaction, he will not be able to do so.

Yes, http protocol is essentially a stateless protocol but to make it stateful we make us of HTTP cookies. So, is SOAP by default. But it can be make stateful likewise, depends upon framework you are using.

HTTP is stateless but still we can maintain session in our java application by using different session tracking mechanism.

Yes, We can also maintain session in webservice whether it is REST or SOAP. It can be implemented by using any third party library or you can implement by our own.

In PHP:

$driver->navigate()->refresh();

Adding one more approach :

value = $(this).val().toLowerCase();
$("#product-search-result tr").filter(function () {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});

I have used the following two:

1 - select id from table_name where id = (select MAX(id) from table_name)
2 - select id from table_name order by id desc limit 0, 1

Try this:

Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

Range("A2:L" & Lastrow).Select

Let's pretend that the value of Lastrow is 50. When you use the following:

Range("A2:L2" & Lastrow).Select

Then it is selecting a range from A2 to L250.

The following works fine on my mac

sed -i.bak 's/foo/bar/g' sample

We are replacing foo with bar in sample file. Backup of original file will be saved in sample.bak

For editing inline without backup, use the following command

sed -i'' 's/foo/bar/g' sample

I would do something like this

<div class="container">
  <div class="text">
    <p>text yay!</p>
  </div>
</div>

CSS:

.container {
    position: relative;
}

.container::before {
    position: absolute;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
    background: url('/path/to/image.png');
    opacity: .4;
    content: "";
    z-index: -1;
}

It should work. This is assuming you are required to have a semi-transparent image BTW, and not a color (which you should just use rgba for). Also assumed is that you can't just alter the opacity of the image beforehand in Photoshop.

For new version instead of:

ipython nbconvert --to python <YourNotebook>.ipynb

You can use jupyter instend of ipython:

jupyter nbconvert --to python <YourNotebook>.ipynb

An alternative ugly method:

   String[] a ={"BLAH00001","DIK-11","DIK-2","MAN5"};
   String[] k=Arrays.toString(a).split(", ",2)[1].split("]")[0].split(", ");

For those who use mybatis, here is an example update statement:

<update id="saveAnswer">
    update quiz_execution set answer_data = jsonb_set(answer_data, concat('{', #{qid}, '}')::text[], #{value}::jsonb), updated_at = #{updatedAt}
    where id = #{id}
</update>

Params:

• qid, the key for field.
• value, is a valid json string, for field value,
  e.g converted from object to json string via jackson,

As someone who has been interested in this for a VERY LONG TIME. See from the manual:

$XDG_CONFIG_HOME/git/config - Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.

Which was only recently added. This dump is from 2.15.0.

Works for me.

What usually works for me is to first change the value of the dropdown, e.g.

$('#selectorForOption').attr('selected','selected')

and then trigger the a change

$('#selectorForOption').changed()

This way, any javascript that is wired to

Bootstrap 4 (update 2019)

A multi-item carousel can be accomplished in several ways as explained here. Another option is to use separate thumbnails to navigate the carousel slides.

Bootstrap 3 (original answer)

This can be done using the grid inside each carousel item.

       <div id="myCarousel" class="carousel slide">
                <div class="carousel-inner">
                    <div class="item active">
                        <div class="row">
                            <div class="col-sm-3">..
                            </div>
                            <div class="col-sm-3">..
                            </div>
                            <div class="col-sm-3">..
                            </div>
                            <div class="col-sm-3">..
                            </div>
                        </div>
                        <!--/row-->
                    </div>
                    ...add more item(s)
                 </div>
        </div>

UDP does have less overhead and is good for doing things like streaming real time data like audio or video, or in any case where it is ok if data is lost.

If all you are trying to do is capture the output from a command, then this will work well.

I use it for changing system time, as [timezoneinfo]::local always produces the same information, even after you have made changes to the system. This is the only way I can validate and log the change in time zone:

$NewTime = (powershell.exe -command [timezoneinfo]::local)
$NewTime | Tee-Object -FilePath $strLFpath\$strLFName -Append

Meaning that I have to open a new PowerShell session to reload the system variables.

You're HASHING, not ENCRYPTING!

What's the difference?

The difference is that hashing is a one way function, where encryption is a two-way function.

So, how do you ascertain that the password is right?

Therefore, when a user submits a password, you don't decrypt your stored hash, instead you perform the same bcrypt operation on the user input and compare the hashes. If they're identical, you accept the authentication.

Should you hash or encrypt passwords?

What you're doing now -- hashing the passwords -- is correct. If you were to simply encrypt passwords, a breach of security of your application could allow a malicious user to trivially learn all user passwords. If you hash (or better, salt and hash) passwords, the user needs to crack passwords (which is computationally expensive on bcrypt) to gain that knowledge.

As your users probably use their passwords in more than one place, this will help to protect them.

Simple reinstall xcode-select

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

The reason that MFC favors protected, is because it is a framework. You probably want to subclass the MFC classes and in that case a protected interface is needed to access methods that are not visible to general use of the class.

Use max-height:100%; max-width:100%; for the image inside the div.

Because these two lines ...

EmployeeService es = new EmployeeService();
CityService cs = new CityService();

... don't take a parameter in the constructor, I guess that you create a context within the classes. When you load the city1...

Payroll.Entities.City city1 = cs.SelectCity(...);

...you attach the city1 to the context in CityService. Later you add a city1 as a reference to the new Employee e1 and add e1 including this reference to city1 to the context in EmployeeService. As a result you have city1 attached to two different context which is what the exception complains about.

You can fix this by creating a context outside of the service classes and injecting and using it in both services:

EmployeeService es = new EmployeeService(context);
CityService cs = new CityService(context); // same context instance

Your service classes look a bit like repositories which are responsible for only a single entity type. In such a case you will always have trouble as soon as relationships between entities are involved when you use separate contexts for the services.

You can also create a single service which is responsible for a set of closely related entities, like an EmployeeCityService (which has a single context) and delegate the whole operation in your Button1_Click method to a method of this service.
