This might help someone:

I am installing the latest Java on my system for development, and currently it's Java SE 7. Now, let's dive into this "madness", as you put it...

All of these are the same (when developers are talking about Java for development):

• Java SE 7
• Java SE v1.7.0
• Java SE Development Kit 7

Starting with Java v1.5:

• v5 = v1.5.
• v6 = v1.6.
• v7 = v1.7.

And we can assume this will remain for future versions.

Next, for developers, download JDK, not JRE.

JDK will contain JRE. If you need JDK and JRE, get JDK. Both will be installed from the single JDK install, as you will see below.

As someone above mentioned:

• JDK = Java Development Kit (developers need this, this is you if you code in Java)
• JRE = Java Runtime Environment (users need this, this is every computer user today)
• Java SE = Java Standard Edition

Here's the step by step links I followed (one step leads to the next, this is all for a single download) to download Java for development (JDK):

1. Visit "Java SE Downloads": http://www.oracle.com/technetwork/java/javase/downloads/index.html
2. Click "JDK Download" and visit "Java SE Development Kit 7 Downloads": http://www.oracle.com/technetwork/java/javase/downloads/java-se-jdk-7-download-432154.html (note that following the link from step #1 will take you to a different link as JDK 1.7 updates, later versions, are now out)
3. Accept agreement :)
4. Click "Java SE Development Kit 7 (Windows x64)": http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-windows-x64.exe (for my 64-bit Windows 7 system)
5. You are now downloading (hopefully the latest) JDK for your system! :)

Keep in mind the above links are for reference purposes only, to show you the step by step method of what it takes to download the JDK.

And install with default settings to:

• “C:\Program Files\Java\jdk1.7.0\” (JDK)
• “C:\Program Files\Java\jre7\” (JRE) <--- why did it ask a new install folder? it's JRE!

Remember from above that JDK contains JRE, which makes sense if you know what they both are. Again, see above.

After your install, double check “C:\Program Files\Java” to see both these folders. Now you know what they are and why they are there.

I know I wrote this for newbies, but I enjoy knowing things in full detail, so I hope this helps.

I've installed and use VB6 for legacy projects many times on Windows 7.

What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

Download here: http://www.microsoft.com/en-us/download/details.aspx?id=5721

Bonus: Also once you install it and realize that scrolling doesn't work, use the below: http://www.joebott.com/vb6scrollwheel.htm

I would definitely suggest using element.getBoundingClientRect().

https://developer.mozilla.org/en-US/docs/Web/API/element.getBoundingClientRect

Summary

Returns a text rectangle object that encloses a group of text rectangles.

Syntax

var rectObject = object.getBoundingClientRect();

Returns

The returned value is a TextRectangle object which is the union of the rectangles returned by getClientRects() for the element, i.e., the CSS border-boxes associated with the element.

The returned value is a TextRectangle object, which contains read-only left, top, right and bottom properties describing the border-box, in pixels, with the top-left relative to the top-left of the viewport.

Here's a browser compatibility table taken from the linked MDN site:

+---------------+--------+-----------------+-------------------+-------+--------+
|    Feature    | Chrome | Firefox (Gecko) | Internet Explorer | Opera | Safari |
+---------------+--------+-----------------+-------------------+-------+--------+
| Basic support | 1.0    | 3.0 (1.9)       | 4.0               | (Yes) | 4.0    |
+---------------+--------+-----------------+-------------------+-------+--------+

It's widely supported, and is really easy to use, not to mention that it's really fast. Here's a related article from John Resig: http://ejohn.org/blog/getboundingclientrect-is-awesome/

You can use it like this:

var logo = document.getElementById('hlogo');
var logoTextRectangle = logo.getBoundingClientRect();

console.log("logo's left pos.:", logoTextRectangle.left);
console.log("logo's right pos.:", logoTextRectangle.right);

Here's a really simple example: http://jsbin.com/awisom/2 (you can view and edit the code by clicking "Edit in JS Bin" in the upper right corner).

Or here's another one using Chrome's console:

Note:

I have to mention that the width and height attributes of the getBoundingClientRect() method's return value are undefined in Internet Explorer 8. It works in Chrome 26.x, Firefox 20.x and Opera 12.x though. Workaround in IE8: for width, you could subtract the return value's right and left attributes, and for height, you could subtract bottom and top attributes (like this).

From XML

In case if you have the web-address/URL displayed on your view and you want it to make it clikable and direct user to particular website You can use:

android:autoLink="web"

In same way you can use different attributes of autoLink(email, phone, map, all) to accomplish your task...

You will need to convert your response to json before you can access response.body

From the docs

fetch(url)
  .then(response => response.json())
  .then(json => {
    console.log('parsed json', json) // access json.body here
  })

I needed a specific solution. I have got an edittext and textview in my layout. The textview is fixed height and width. When the user starts to type in the edittext, the text should immediately appear in the textview. The text in the textfield should auto - resize to fit the textview. So I updated Chase's solution to work for me. So when the text changes in the textview, resizing starts. The difference between mine and Chase's soluton: resizing is done even if the user DELETE some chars. I hope it can help someone.

public class TextFitTextView extends TextView {

// Minimum text size for this text view
public static final float MIN_TEXT_SIZE = 10;

// Maximum text size for this text view - if it is 0, then the text acts
// like match_parent
public static final float MAX_TEXT_SIZE = 0;

// Our ellipse string
private static final String mEllipsis = "...";

// Text size that is set from code. This acts as a starting point for
// resizing
private float mTextSize;

// Lower bounds for text size
private float mMinTextSize = MIN_TEXT_SIZE;

// Max bounds for text size

// Text view line spacing multiplier

// Text view additional line spacing

Another way assuming it's not server side code you want to comment out is...

<asp:panel runat="server" visible="false">
    html here
</asp:panel>

Yes, you can. Download the plugin (*.hpi file) and put it in the following directory:

<jenkinsHome>/plugins/

Afterwards you will need to restart Jenkins.

You can force it (browser permitting, I imagine) by inserting line breaks in the HTML source, like this:

<INPUT value="Line 1
Line 2">

Of course working out where to place the line breaks is not necessarily trivial...

If you can use an HTML <BUTTON> instead of an <INPUT>, such that the button label is the element's content rather than its value attribute, placing that content inside a <SPAN> with a width attribute that is a few pixels narrower than that of the button seems to do the trick (even in IE6 :-).

Josh's comments are spot on. If you are not super familiar with critical values I'd suggest playing with qt, reading the manual (?qt) in conjunction with looking at a look up table (LINK). When I first moved from SPSS to R I created a function that made critical t value look up pretty easy (I'd never use this now as it takes too much time and with the p values that are generally provided in the output it's a moot point). Here's the code for that:

critical.t <- function(){
    cat("\n","\bEnter Alpha Level","\n")
    alpha<-scan(n=1,what = double(0),quiet=T)
    cat("\n","\b1 Tailed or 2 Tailed:\nEnter either 1 or 2","\n")
    tt <- scan(n=1,what = double(0),quiet=T)
    cat("\n","\bEnter Number of Observations","\n")
    n <- scan(n=1,what = double(0),quiet=T)
    cat("\n\nCritical Value =",qt(1-(alpha/tt), n-2), "\n")
}

critical.t()

As an update, for Angular 7, a very good example, loading plus http interceptor, here: https://nezhar.com/blog/create-a-loading-screen-for-angular-apps/.

For version 6, you need a small adjustment when you use Subject. You need to add the generic type.

loadingStatus: Subject<boolean> = new Subject();

I'm using angular material, so instead of a loading text, you can use mat-spinner.

<mat-spinner></mat-spinner>

Update: the code from the previous page will not complete work (regarding the interceptor part), but here you have the complete solution: https://github.com/nezhar/snypy-frontend

And as Miranda recommended into comments, here is also the solution:

The loading screen component:

loading-screen.component.ts

    import { Component, ElementRef, ChangeDetectorRef, OnDestroy, AfterViewInit } from '@angular/core';
import { Subscription } from 'rxjs';
import { LoadingScreenService } from '../services/loading-screen.service';

@Component({
  selector: 'app-loading-screen',
  templateUrl: './loading-screen.component.html',
  styleUrls: ['./loading-screen.component.css']
})
export class LoadingScreenComponent implements AfterViewInit, OnDestroy {

  loading: boolean = false;
  loadingSubscription: Subscription;

  constructor(
    private loadingScreenService: LoadingScreenService,
    private _elmRef: ElementRef,
    private _changeDetectorRef: ChangeDetectorRef
  ) { }

  ngAfterViewInit(): void {
    this._elmRef.nativeElement.style.display = 'none';
    this.loadingSubscription = this.loadingScreenService.loadingStatus.pipe().subscribe(
      (status: boolean) => {
        this._elmRef.nativeElement.style.display = status ? 'block' : 'none';
        this._changeDetectorRef.detectChanges();
      }
    );
  }

  ngOnDestroy() {
    console.log("inside destroy loading component");
    this.loadingSubscription.unsubscribe();
  }

}

loading-screen.component.html

<div id="overlay">
  <mat-spinner class="content"></mat-spinner>
</div>

loading-screen.component.css

  #overlay {
      position: fixed; /* Sit on top of the page content */
      display: block; /* Hidden by default */
      width: 100%; /* Full width (cover the whole page) */
      height: 100%; /* Full height (cover the whole page) */
      top: 0;
      left: 0;
      right: 0;
      bottom: 0;
      background-color: rgba(60, 138, 255, 0.1); /* Black background with opacity */
      opacity: 0.5;
      z-index: 2; /* Specify a stack order in case you're using a different order for other elements */
      cursor: progress; /* Add a pointer on hover */
  }

  .content {
      position: absolute;
      top: 50%;
      left: 50%;
      font-size: 50px;
      color: white;
      transform: translate(-50%, -50%);
      -ms-transform: translate(-50%, -50%);
  }

Don't forget to add the component to your root component. In my case, AppComponent

app.component.html

<app-loading-screen></app-loading-screen>

The service that will manage the component: loading-screen.service.ts

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

@Injectable({
  providedIn: 'root'
})
export class LoadingScreenService {

  constructor() { }

  private _loading: boolean = false;
  loadingStatus: Subject<boolean> = new Subject();

  get loading(): boolean {
    console.log("get loading: " + this._loading);
    return this._loading;
  }

  set loading(value) {
    console.log("get loading: " + value);
    this._loading = value;
    this.loadingStatus.next(value);
  }

  startLoading() {
    console.log("startLoading");
    this.loading = true;
  }

  stopLoading() {
    console.log("stopLoading");
    this.loading = false;
  }
}

Here is the http interceptor, which will show/hide the component, using the previous service.

loading-screen-interceptor.ts

import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpRequest, HttpHandler, HttpEvent } from '@angular/common/http';
import { LoadingScreenService } from '../services/loading-screen.service';
import { Observable } from 'rxjs';
import { finalize } from 'rxjs/operators';

@Injectable()
export class LoadingScreenInterceptor implements HttpInterceptor {

    activeRequests: number = 0;

    constructor(
        private loadingScreenService: LoadingScreenService
    ) { }

    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

        console.log("inside interceptor");

        if (this.activeRequests === 0) {
            this.loadingScreenService.startLoading();
        }

        this.activeRequests++;

        return next.handle(request).pipe(
            finalize(() => {
                this.activeRequests--;
                if (this.activeRequests === 0) {
                    this.loadingScreenService.stopLoading();
                }
            })
        )
    };
}

And in your app.module.ts, don't forget to config the interceptor

providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: LoadingScreenInterceptor,
      multi: true
    }
  ]

You need to do this via an extension as of the version 1.8.1.

1. Go to View ? Extensions. This will open Extensions Panel.

2. Type bookmark to list all related extensions.

3. Install

I personally like "Numbered Bookmarks" - it is pretty simple and powerful.

Go to the line you need to create a bookmark.

Click Ctrl + Shift + [some number]

Ex: Ctrl + Shift + 2

Now you can jump to this line from anywhere by pressing Ctrl + number

Ex: Ctrl + 2

If you are using ContentProvider then you can use:

Cursor cursor = getContentResolver().query(CONTENT_URI, new String[] {"count(*)"},
            uname=" + loginname + " and pwd=" + loginpass, null, null);
    cursor.moveToFirst();
    int count = cursor.getInt(0);

var validation = {
    isEmailAddress:function(str) {
        var pattern =/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
        return pattern.test(str);  // returns a boolean
    },
    isNotEmpty:function (str) {
        var pattern =/\S+/;
        return pattern.test(str);  // returns a boolean
    },
    isNumber:function(str) {
        var pattern = /^\d+$/;
        return pattern.test(str);  // returns a boolean
    },
    isSame:function(str1,str2){
        return str1 === str2;
    }
};   

alert(validation.isNotEmpty("dff"));
alert(validation.isNumber(44));
alert(validation.isEmailAddress("[email protected]"));
alert(validation.isSame("sf","sf"));

R defines a ~ (tilde) operator for use in formulas. Formulas have all sorts of uses, but perhaps the most common is for regression:

library(datasets)
lm( myFormula, data=iris)

help("~") or help("formula") will teach you more.

@Spacedman has covered the basics. Let's discuss how it works.

First, being an operator, note that it is essentially a shortcut to a function (with two arguments):

> `~`(lhs,rhs)
lhs ~ rhs
> lhs ~ rhs
lhs ~ rhs

That can be helpful to know for use in e.g. apply family commands.

Second, you can manipulate the formula as text:

oldform <- as.character(myFormula) # Get components
myFormula <- as.formula( paste( oldform[2], "Sepal.Length", sep="~" ) )

Third, you can manipulate it as a list:

myFormula[[2]]
myFormula[[3]]

Finally, there are some helpful tricks with formulae (see help("formula") for more):

myFormula <- Species ~ . 

For example, the version above is the same as the original version, since the dot means "all variables not yet used." This looks at the data.frame you use in your eventual model call, sees which variables exist in the data.frame but aren't explicitly mentioned in your formula, and replaces the dot with those missing variables.

To print a vector which possibly has complex numbers-

fprintf('Answer: %s\n', sprintf('%d ', num2str(x)));

Just for the record, using H2 as testing database, and MySQL at runtime, this approach works (example is newest object in group):

@Query(value = "SELECT t.* FROM t LEFT JOIN t AS t_newer " +
        "ON t.object_id = t_newer.object_id AND t.id < t_newer.id AND o_newer.user_id IN (:user_ids) " +
        "WHERE t_newer.id IS NULL AND t.user_id IN (:user_ids) " +
        "ORDER BY t.id DESC \n-- #pageable\n",
        countQuery = "SELECT COUNT(1) FROM t WHERE t.user_id IN (:user_ids) GROUP BY t.object_id, t.user_id",
        nativeQuery = true)
Page<T> findByUserIdInGroupByObjectId(@Param("user_ids") Set<Integer> userIds, Pageable pageable);

Spring Data JPA 1.10.5, H2 1.4.194, MySQL Community Server 5.7.11-log (innodb_version 5.7.11).

Wouldn't it be better to "wrap" the String in order to memorize the hashCode. In the normal String class hashCode() is O(N) the first time and then it is O(1) since it is kept for future use.

public class HashWrap {
    private final String value;
    private final int hash;

    public String get() {
        return value;
    }

    public HashWrap(String value) {
        this.value = value;
        String lc = value.toLowerCase();
        this.hash = lc.hashCode();
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o instanceof HashWrap) {
            HashWrap that = (HashWrap) o;
            return value.equalsIgnoreCase(that.value);
        } else {
            return false;
        }
    }

    @Override
    public int hashCode() {
        return this.hash;
    }

    //might want to implement compare too if you want to use with SortedMaps/Sets.
}

This would allow you to use any implementation of Hashtable in java and to have O(1) hasCode().

Try this if other answers did not work for you.

For me This happened for API 27 Emulator.

API 26 Emulator worked just fine. So I started API 26 Emulator first and then closed it.

Then I started API 27 Emulator and It worked with No errors at all.

(2) Create a login for the non-sysadmin user that has public access to the master database

I went to my user's database list (server/security/connections/my user name/properties/user mapping, and wanted to check the box for master database. I got an error message telling that the user already exists in the master database. Went to master database, dropped the user, went back to "user mapping" and checked the box for master. Check the "public" box below.

After that, you need to re-issue the grant execute on xp_cmdshell to "my user name"

I came here looking for exporting blob into file with least effort. CLR functions is not something what I'd call least effort. Here described lazier one, using OLE Automation:

declare @init int
declare @file varbinary(max) = CONVERT(varbinary(max), N'your blob here')
declare @filepath nvarchar(4000) = N'c:\temp\you file name here.txt'

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1; 
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @file; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @filepath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources

You'll potentially need to allow to run OA stored procedures on server (and then turn it off, when you're done):

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

char_seen = []
for char in string:
    if char not in char_seen:
        char_seen.append(char)
print(''.join(char_seen))

This will preserve the order in which alphabets are coming,

output will be

abcd

It could be something as simple as setting a text field / label value or adding a subview inside a background thread, which may cause a field's layout to change. Make sure anything you do with the interface only happens in the main thread.

Below connection string is working

sql_conn = odbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER=SERVER_NAME;DATABASE=DATABASE_NAME;UID=USERNAME;PWD=PASSWORD;')

query = "SELECT * FROM admin.TABLE_NAME"
df = pd.read_sql(query, sql_conn)

This is a more modern awaitable, Task Parallel Library (TPL) based solution for .NET 4.5 and above.

Usage Example

try

    var exitCode = await StartProcess(
        "dotnet", 
        "--version", 
        @"C:\",
        10000, 
        Console.Out, 
        Console.Out);
    Console.WriteLine($"Process Exited with Exit Code {exitCode}!");
}
catch (TaskCanceledException)
{
    Console.WriteLine("Process Timed Out!");
}

In the meantime, result.fillna('') should do what you want

EDIT: in the development version (to be 0.8.0 final) if you specify an empty list of na_values, empty strings will stay empty strings in the result

The simplest way: just open the .dll in any text editor. Look at one of the last lines:

(function( $ ) {
  $.fn.keepRatio = function(which) {
      var $this = $(this);
      var w = $this.width();
      var h = $this.height();
      var ratio = w/h;
      $(window).resize(function() {
          switch(which) {
              case 'width':
                  var nh = $this.width() / ratio;
                  $this.css('height', nh + 'px');
                  break;
              case 'height':
                  var nw = $this.height() * ratio;
                  $this.css('width', nw + 'px');
                  break;
          }
      });

  }
})( jQuery );      

$(document).ready(function(){
    $('#foo').keepRatio('width');
});

ScrollView sView = (ScrollView)findViewById(R.id.deal_web_view_holder);

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

Axios does not support canceling requests at the moment. Please see this issue for details.

UPDATE: Cancellation support was added in axios v0.15.

EDIT: The axios cancel token API is based on the withdrawn cancelable promises proposal.

Example:

const cancelTokenSource = axios.CancelToken.source();

axios.get('/user/12345', {
  cancelToken: cancelTokenSource.token
});

// Cancel request
cancelTokenSource.cancel();

There's now add_row() from the tibble or tidyverse packages.

library(tidyverse)
df %>% add_row(hello = "hola", goodbye = "ciao")

Unspecified columns get an NA.

That is the HTML code. Anyone can use this:

<div class="card-header">Contact Information</div>
          <div class="card-body" formArrayName="funds">
            <div class="row">
              <div class="col-6" *ngFor="let contact of contactFormGroup.controls; let i = index;">
                <div [formGroupName]="i" class="row">
                  <div class="form-group col-6">
                    <label>Type of Contact</label>
                    <select class="form-control" formControlName="fundName" type="text">
                      <option value="01">Balance Fund</option>
                      <option value="02">Equity Fund</option>
                    </select> 
                  </div>
                  <div class="form-group col-12">
                    <label>Allocation</label>
                    <input class="form-control" formControlName="allocation" type="number">
                    <span class="text-danger" *ngIf="getContactsFormGroup(i).controls['allocation'].touched && 
                    getContactsFormGroup(i).controls['allocation'].hasError('required')">
                        Allocation % is required! </span>
                  </div>
                  <div class="form-group col-12 text-right">
                    <button class="btn btn-danger" type="button" (click)="removeContact(i)"> Remove </button>
                  </div>
                </div>
              </div>
            </div>

This might be completely off base, but can't you just copy the whole column into a new spreadsheet and then sort the column? I'm assuming that you don't need to maintain the order integrity.

1. Look at the folders drawable-hdpi, drawable-mdpi, drawable-xhdpi and so on.
2. If there is a wrong bitmap file, Delete it and resave.
3. Go to Build->Rebuild Project

The simplest way is:

const { exec } = require("child_process")
exec('yourApp').unref()

unref is necessary to end your process without waiting for "yourApp"

Here are the exec docs

Another option is to add style to div

<div style="position: absolute; height:somePercentage%; overflow:auto(or other overflow value)">
 //to be scrolled 
</div>

And it means that an element is positioned relative to the nearest positioned ancestor.

please try these

<form action="Delegate_update.php" method="post">
Name
<input type="text" name= "Name" value= "<?php echo $row['Name']; ?> "size=10>
Username
<input type="text" name= "User_name" value= "<?php echo $row['User_name']; ?> "size=10>
Password
<input type="text" name= "User_password" value= "<?php echo $row['User_password']; ?>" size=17>
<input type="submit" name= "submit" value="Update">
</form>

To achieve it, you have to modify the background-color of the element.

Ways to create a (semi-) transparent color:

• The CSS color name transparent creates a completely transparent color.

  Usage:

    .transparent{
      background-color: transparent;
    }
  

• Using rgba or hsla color functions, that allow you to add the alpha channel (opacity) to the rgb and hsl functions. Their alpha values range from 0 - 1.

  Usage:

    .semi-transparent-yellow{
      background-color: rgba(255, 255, 0, 0.5);
    }
    .transparent{
      background-color:  hsla(0, 0%, 0%, 0);
    }
  

• Besides the already mentioned solutions, you can also use the HEX format with alpha value (#RRGGBBAA or #RGBA notation).

  That's pretty new (contained by CSS Color Module Level 4), but already implemented in larger browsers (sorry, no IE).

  This differs from the other solutions, as this treats the alpha channel (opacity) as a hexadecimal value as well, making it range from 0 - 255 (FF).

  Usage:

    .semi-transparent-yellow{
      background-color: #FFFF0080;
    }
    .transparent{
      background-color: #0000;
    }
  

You can try them out as well:

• transparent:

div {
  position: absolute;
  top: 50px;
  left: 100px;
  height: 100px;
  width: 200px;
  text-align: center;
  line-height: 100px;
  border: 1px dashed grey;
  
  background-color: transparent;
}

<img src="https://via.placeholder.com/200x100">
<div>
  Using `transparent`
</div>

• rgba():

div {
  position: absolute;
  top: 50px;
  left: 100px;
  height: 100px;
  width: 200px;
  text-align: center;
  line-height: 100px;
  border: 1px dashed grey;
  
  background-color: rgba(0, 255, 0, 0.3);
}

<img src="https://via.placeholder.com/200x100">
<div>
  Using `rgba()`
</div>

• #RRGGBBAA:

div {
  position: absolute;
  top: 50px;
  left: 100px;
  height: 100px;
  width: 200px;
  text-align: center;
  line-height: 100px;
  border: 1px dashed grey;
  
  background-color: #FF000060
}

<img src="https://via.placeholder.com/200x100">
<div>
  Using `#RRGGBBAA`
</div>

Do something like this:

A <div> with ID of #imageDIV, another one with ID #download and a hidden <div> with ID #previewImage.

Include the latest version of jquery, and jspdf.debug.js from the jspdf CDN

Then add this script:

var element = $("#imageDIV"); // global variable
var getCanvas; // global variable
$('document').ready(function(){
  html2canvas(element, {
    onrendered: function (canvas) {
      $("#previewImage").append(canvas);
      getCanvas = canvas;
    }
  });
});
$("#download").on('click', function () {
  var imgageData = getCanvas.toDataURL("image/png");
  // Now browser starts downloading it instead of just showing it
  var newData = imageData.replace(/^data:image\/png/, "data:application/octet-stream");
  $("#download").attr("download", "image.png").attr("href", newData);
});

The div will be saved as a PNG on clicking the #download

If at all possible, use generics. This includes:

• List instead of ArrayList
• Dictionary instead of HashTable

UPDATE: For Bootstrap 5

The class name is now "float-end" instead of "pull-right"

<div class="alert alert-info clearfix">
    <a href="#" class="alert-link">
      Summary:Its some description.......testtesttest
    </a> 
    <button type="button" class="btn btn-primary btn-lg float-end">
      Large button
    </button>
</div>

For Bootstrap 4 and under

Just add a simple pull-right class to the button, and make sure the container div is clearfixed:

<div class="alert alert-info clearfix">
    <a href="#" class="alert-link">
      Summary:Its some description.......testtesttest
    </a> 
    <button type="button" class="btn btn-primary btn-lg pull-right">
      Large button
    </button>
</div>

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

from foo import * 

adds all the names without leading underscores (or only the names defined in the modules __all__ attribute) in foo into your current module.

In the above code with from socket import * you just want to catch timeout as you've pulled timeout into your current namespace.

from socket import * pulls in the definitions of everything inside of socket but doesn't add socket itself.

try:
    # socketstuff
except timeout:
    print 'caught a timeout'

Many people consider import * problematic and try to avoid it. This is because common variable names in 2 or more modules that are imported in this way will clobber one another.

For example, consider the following three python files:

# a.py
def foo():
    print "this is a's foo function"

# b.py
def foo():
    print "this is b's foo function"

# yourcode.py
from a import *
from b import *
foo()

If you run yourcode.py you'll see just the output "this is b's foo function".

For this reason I'd suggest either importing the module and using it or importing specific names from the module:

For example, your code would look like this with explicit imports:

import socket
from socket import AF_INET, SOCK_DGRAM

def main():
    client_socket = socket.socket(AF_INET, SOCK_DGRAM)
    client_socket.settimeout(1)
    server_host = 'localhost'
    server_port = 1234
    while(True):
        client_socket.sendto('Message', (server_host, server_port))
        try:
            reply, server_address_info = client_socket.recvfrom(1024)
            print reply
        except socket.timeout:
            #more code

Just a tiny bit more typing but everything's explicit and it's pretty obvious to the reader where everything comes from.

You can simply use the method change of JQuery to get the value of the current radio checked with the following code:

$(document).on('change', '[type="radio"]', function() {
    var currentlyValue = $(this).val(); // Get the radio checked value
        
    alert('Currently value: '+currentlyValue); // Show a alert with the current value
});

You can change the selector '[type="radio"]' for a class or id that you want.

Edit /etc/paths. Then close the terminal and reopen it.

$ sudo vi /etc/paths

Note: each entry is seperated by line breaks.

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

If the size of the list if fixed, then you can use an AtomicReferenceArray. This would allow you to perform indexed updates to a slot. You could write a List view if needed.

I spent about an hour looking for a more robust javascript option, and did not find one. It just so happens that in the past few days I've been fiddling with hammer.js (Hammer.js is a library that lets you manipulate all sorts of touch events easily) and mostly failing at what I was trying to do.

With that caveat, and understanding I am by no means a javascript expert, this is a solution I came up with that basically leverages hammer.js to capture the pinch-zoom and double-tap events and then log and discard them.

Make sure you include hammer.js in your page and then try sticking this javascript in the head somewhere:

< script type = "text/javascript" src="http://hammerjs.github.io/dist/hammer.min.js"> < /script >_x000D_
< script type = "text/javascript" >_x000D_
_x000D_
  // SPORK - block pinch-zoom to force use of tooltip zoom_x000D_
  $(document).ready(function() {_x000D_
_x000D_
    // the element you want to attach to, probably a wrapper for the page_x000D_
    var myElement = document.getElementById('yourwrapperelement');_x000D_
    // create a new hammer object, setting "touchAction" ensures the user can still scroll/pan_x000D_
    var hammertime = new Hammer(myElement, {_x000D_
      prevent_default: false,_x000D_
      touchAction: "pan"_x000D_
    });_x000D_
_x000D_
    // pinch is not enabled by default in hammer_x000D_
    hammertime.get('pinch').set({_x000D_
      enable: true_x000D_
    });_x000D_
_x000D_
    // name the events you want to capture, then call some function if you want and most importantly, add the preventDefault to block the normal pinch action_x000D_
    hammertime.on('pinch pinchend pinchstart doubletap', function(e) {_x000D_

I would advise reading Java puzzlers. It explains inheritance, generics, abstractions, and wildcards in declarations quite well. http://www.javapuzzlers.com/

I know it's 2 years late, but these answers helped me to formulate a filter function to output objects and trim the resulting strings. Since I have to format everything into a string in my final solution I went about things a little differently. Long-hand, my problem is very similar, and looks a bit like this

$verbosepreference="Continue"
write-verbose (ls | ft | out-string) # this generated too many blank lines

Here is my example:

ls | Out-Verbose # out-verbose formats the (pipelined) object(s) and then trims blanks

My Out-Verbose function looks like this:

filter Out-Verbose{
Param([parameter(valuefrompipeline=$true)][PSObject[]]$InputObject,
      [scriptblock]$script={write-verbose "$_"})
  Begin {
    $val=@()
  }
  Process {
    $val += $inputobject
  }
  End {
    $val | ft -autosize -wrap|out-string |%{$_.split("`r`n")} |?{$_.length} |%{$script.Invoke()}
  }
}

Note1: This solution will not scale to like millions of objects(it does not handle the pipeline serially)

Note2: You can still add a -noheaddings option. If you are wondering why I used a scriptblock here, that's to allow overloading like to send to disk-file or other output streams.

use the limit clausule, with the offset to choose the row number -1 so if u wanna get the number 8 row so use:

limit 1 offset 7

Add this two line in your style.xml

<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>

same here, updating to 0.4.2 also broke everything in my case... It has nothing to do with memory usage : I've got 8 gig of memory and I have 3.5 gig free atm, so not having enough memory to start up a JVM is bullocks...

Actually it might have something to do with Gradle versions, I looked into the error log and found this :

2014-01-14 09:00:30,918 [ 61112] WARN - nal.AbstractExternalSystemTask - Project is using an old version of the Android Gradle plug-in. The minimum supported version is 0.7.0. Please update the version of the dependency 'com.android.tools.build:gradle' in your build.gradle files.

-

You are using Gradle version 1.8, which is not supported. Please use version 1.9.

Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.)

OK, I fixed it myself... In the project directory go to /gradle/wrapper directory and edit the gradle-wrapper properties file to this :

distributionUrl=http\://services.gradle.org/distributions/gradle-1.9-all.zip

After open your project in Android Studio and select the build.gradle file in the /src directory and edit it to this :

dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }

After fixing it like this I discovered this article : http://tools.android.com/recent/androidstudio040released

You could use a "variable" inside the output filename, for example:

/tmp/FetchBlock-${current_date}.txt

current_date:

Returns the current system time formatted as yyyyMMdd_HHmm. An optional argument can be used to provide alternative formatting. The argument must be valid pattern for java.util.SimpleDateFormat.

Or you can also use a system_property or an env_var to specify something dynamic (either one needs to be specified as arguments)

Try:

SELECT MEMBSHIP_ID
  FROM user_payment
 WHERE user_id=1 
ORDER BY paym_date = (select MAX(paym_date) from user_payment and user_id=1);

Or:

SELECT MEMBSHIP_ID
FROM (
  SELECT MEMBSHIP_ID, row_number() over (order by paym_date desc) rn
      FROM user_payment
     WHERE user_id=1 )
WHERE rn = 1

This is a pretty old question, and while looking for Git libraries, I found one that was made this year (2013) called Gittle.

It worked great for me (where the others I tried were flaky), and seems to cover most of the common actions.

Some examples from the README:

from gittle import Gittle

# Clone a repository
repo_path = '/tmp/gittle_bare'
repo_url = 'git://github.com/FriendCode/gittle.git'
repo = Gittle.clone(repo_url, repo_path)

# Stage multiple files
repo.stage(['other1.txt', 'other2.txt'])

# Do the commit
repo.commit(name="Samy Pesse", email="[email protected]", message="This is a commit")

# Authentication with RSA private key
key_file = open('/Users/Me/keys/rsa/private_rsa')
repo.auth(pkey=key_file)

# Do push
repo.push()

If you are searching for the index of the last occurrence of myvalue in mylist:

len(mylist) - mylist[::-1].index(myvalue) - 1

You can do with little Trick: Suppose you have requirement of : ( Width,Height )

Wrap_content ,Wrap_content :

 //use this as child
 Wrap(
  children: <Widget>[*your_child*])

Match_parent,Match_parent:

 //use this as child
Container(
        height: double.infinity,
    width: double.infinity,child:*your_child*)

Match_parent,Wrap_content :

 //use this as child
Row(
  mainAxisSize: MainAxisSize.max,
  children: <Widget>[*your_child*],
);

Wrap_content ,Match_parent:

 //use this as child
Column(
  mainAxisSize: MainAxisSize.max,
  children: <Widget>[your_child],
);

The "best" answer has already been submitted, but I thought I would add that you can use nested list comprehensions, as seen in the Python Tutorial.

Here is how you could get a transposed array:

def matrixTranspose( matrix ):
    if not matrix: return []
    return [ [ row[ i ] for row in matrix ] for i in range( len( matrix[ 0 ] ) ) ]

You can do this with the "rebase" command. Let's call the branches "main" and "feature":

git checkout feature
git rebase main

The rebase command will replay all of the commits on "feature" as one commit with a parent equal to "main".

You might want to run git merge main before git rebase main if "main" has changed since "feature" was created (or since the most recent merge). That way, you still have your full history in case you had a merge conflict.

After the rebase, you can merge your branch to main, which should result in a fast-forward merge:

git checkout main
git merge feature

See the rebase page of Understanding Git Conceptually for a good overview

I solved this problem by adding another div as a sibling to the scrolling content div. It's height is set to the radius of the curved borders. There will be design issues if you have content that you want nudged to the very bottom, or text you want to flow into this new div, etc,. but for my UI this thin div is no problem.

The real trick is to have the following structure:

<div class="window">
 <div class="title">Some title text</div>
 <div class="content">Main content area</div>
 <div class="footer"></div>
</div>

Important CSS highlights:

• Your CSS would define the content region with a height and overflow to allow the scrollbar(s) to appear.
• The window class gets the same diameter corners as the title and footer
• The drop shadow, if desired, is only given to the window class
• The height of the footer div is the same as the radius of the bottom corners

Here's what that looks like:

This solution
a) is only MySQL, no other language needed, and
b) returns SQL results, ready for processing!

#Search multiple database tables and/or columns

The standard approach is to use sprintf(buffer, "%lu", value); to write a string rep of value to buffer. However, overflow is a potential problem, as sprintf will happily (and unknowingly) write over the end of your buffer.

This is actually a big weakness of sprintf, partially fixed in C++ by using streams rather than buffers. The usual "answer" is to allocate a very generous buffer unlikely to overflow, let sprintf output to that, and then use strlen to determine the actual string length produced, calloc a buffer of (that size + 1) and copy the string to that.

This site discusses this and related problems at some length.

Some libraries offer snprintf as an alternative which lets you specify a maximum buffer size.

Many solutions here did not account for rounding. For example:

Event happened at 3pm two days ago. If you are checking at 2pm, it will show one day ago. If you are checking at 4pm it will show two days ago.

If you are working with unix time, this helps:

// how long since event has passed in seconds
$secs = time() - $time_ago;

// how many seconds in a day
$sec_per_day = 60*60*24;

// days elapsed
$days_elapsed = floor($secs / $sec_per_day);

// how many seconds passed today
$today_seconds = date('G')*3600 + date('i') * 60 + date('s');

// how many seconds passed in the final day calculation
$remain_seconds = $secs % $sec_per_day;

if($today_seconds < $remain_seconds)
{
    $days_elapsed++;
}

echo 'The event was '.$days_ago.' days ago.';

It is not perfect if you are worried about leap seconds and daylight savings time.

Could you provide a whole makefile? But right now I can tell - you should check that "install" target already exists. So, check Makefile whether it contains a

install: (anything there)

line. If not, there is no such target and so make has right. Probably you should use just "make" command to compile and then use it as is or install yourself, manually.

Install is not any standard of make, it is just a common target, that could exists, but not necessary.

By selecting 'Class Library' you were accidentally telling it to make a .Net Library using the CLI (managed) extenstion of C++.

Instead, create a Win32 project, and in the Application Settings on the next page, choose 'DLL'.

You can also make an MFC DLL or ATL DLL from those library choices if you want to go that route, but it sounds like you don't.

you can also add inline css for adding image as a background as per below example

<div class="item active" style="background-image: url(../../foo.png);">

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

You've told jQuery to expect a JSONP response, which is why jQuery has added the callback=jQuery16406345664265099913_1319854793396&_=1319854793399 part to the URL (you can see this in your dump of the request).

What you're returning is JSON, not JSONP. Your response looks like

{"red" : "#f00"}

and jQuery is expecting something like this:

jQuery16406345664265099913_1319854793396({"red" : "#f00"})

If you actually need to use JSONP to get around the same origin policy, then the server serving colors.json needs to be able to actually return a JSONP response.

If the same origin policy isn't an issue for your application, then you just need to fix the dataType in your jQuery.ajax call to be json instead of jsonp.

Yet another solution. With True and False you get a little feedback about the test at the end.

data = {True: data[:75] + '..', False: data}[len(data) > 75]

You can add the index directly to your entry config and using a file-loader to load it

module.exports = {

  entry: [
    __dirname + "/index.html",
    .. other js files here
  ],

  module: {
    rules: [
      {
        test: /\.html/, 
        loader: 'file-loader?name=[name].[ext]', 
      },
      .. other loaders
    ]
  }

}

For Swift 3

UserDefaults.standard.setValue(token, forKey: "user_auth_token")
print("\(UserDefaults.standard.value(forKey: "user_auth_token")!)")

You would simply need to do this in your onClick:

AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Alert");
alertDialog.setMessage("Alert message to be shown");
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
alertDialog.show();

I don't know from where you saw that you need DialogFragment for simply showing an alert.

Hope this helps.

Another important consideration: The Elvis Operator breaks the Zend Opcache tokenization process. I found this the hard way! While this may have been fixed in later versions, I can confirm this problem exists in PHP 5.5.38 (with in-built Zend Opcache v7.0.6-dev).

If you find that some of your files 'refuse' to be cached in Zend Opcache, this may be one of the reasons... Hope this helps!

Is the ??? free to be defined by the user?

Yes.

or is it supplied by the HTML?

No. HTML has nothing to do with that. Read below.

Is it possible for me to define the ??? as abcdefg?

Yes.

If you want to send the following data to the web server:

name = John
age = 12

using application/x-www-form-urlencoded would be like this:

name=John&age=12

As you can see, the server knows that parameters are separated by an ampersand &. If & is required for a parameter value then it must be encoded.

So how does the server know where a parameter value starts and ends when it receives an HTTP request using multipart/form-data?

Using the boundary, similar to &.

For example:

--XXX
Content-Disposition: form-data; name="name"

John
--XXX
Content-Disposition: form-data; name="age"

12
--XXX--

In that case, the boundary value is XXX. You specify it in the Content-Type header so that the server knows how to split the data it receives.

So you need to:

• Use a value that won't appear in the HTTP data sent to the server.

• Be consistent and use the same value everywhere in the request message.

Sometimes depend and by git version and if you forget to do git add ..

To check about your change on repository use always git status that show all untracked and changed files. Because git diff show only added files.

Try printing out this way

printf("%%");

Didn't feel like doing it by hand as in bobince's answer, so I just completely ripped off jQuery's plugin options pattern.

Here's the constructor:

//default constructor for Preset 'class'
function Preset(params) {
    var properties = $.extend({
        //these are the defaults
        id: null,
        name: null,
        inItems: [],
        outItems: [],
    }, params);

    console.log('Preset instantiated');
    this.id = properties.id;
    this.name = properties.name;
    this.inItems = properties.inItems;
    this.outItems = properties.outItems;
}

Here's different ways of instantiation:

presetNoParams = new Preset(); 
presetEmptyParams = new Preset({});
presetSomeParams = new Preset({id: 666, inItems:['item_1', 'item_2']});
presetAllParams = new Preset({id: 666, name: 'SOpreset', inItems: ['item_1', 'item_2'], outItems: ['item_3', 'item_4']});

And here's what that made:

presetNoParams
Preset {id: null, name: null, inItems: Array[0], outItems: Array[0]}

presetEmptyParams
Preset {id: null, name: null, inItems: Array[0], outItems: Array[0]}

presetSomeParams
Preset {id: 666, name: null, inItems: Array[2], outItems: Array[0]}

presetAllParams
Preset {id: 666, name: "SOpreset", inItems: Array[2], outItems: Array[2]}

A common error that is the cause of this is when you add

@Model SampleModel

at the top of the page instead of

@model SampleModel

The regex you're looking for is ^[A-Za-z.\s_-]+$

• ^ asserts that the regular expression must match at the beginning of the subject
• [] is a character class - any character that matches inside this expression is allowed
• A-Z allows a range of uppercase characters
• a-z allows a range of lowercase characters
• . matches a period rather than a range of characters
• \s matches whitespace (spaces and tabs)
• _ matches an underscore
• - matches a dash (hyphen); we have it as the last character in the character class so it doesn't get interpreted as being part of a character range. We could also escape it (\-) instead and put it anywhere in the character class, but that's less clear
• + asserts that the preceding expression (in our case, the character class) must match one or more times
• $ Finally, this asserts that we're now at the end of the subject

When you're testing regular expressions, you'll likely find a tool like regexpal helpful. This allows you to see your regular expression match (or fail to match) your sample data in real time as you write it.

Looking at posted answers I think this code would be also an alternative for someone. Nobody above used .Shapes.AddPicture in their code, only .Pictures.Insert()

Dim myPic As Object
Dim picpath As String

picpath = "C:\Users\photo.jpg" 'example photo path

Set myPic = ws.Shapes.AddPicture(picpath, False, True, 20, 20, -1, -1)

With myPic
    .Width = 25
    .Height = 25
    .Top = xlApp.Cells(i, 20).Top 'according to variables from correct answer
    .Left = xlApp.Cells(i, 20).Left
    .LockAspectRatio = msoFalse
End With

I'm working in Excel 2013. Also realized that You need to fill all the parameters in .AddPicture, because of error "Argument not optional". Looking at this You may ask why I set Height and Width as -1, but that doesn't matter cause of those parameters are set underneath between With brackets.

Hope it may be also useful for someone :)

If you can pick a reasonable maximum line length, you can seek to nearly the end of the file before you start reading.

myfile.seek(-max_line_length, os.SEEK_END)
line = myfile.readlines()[-1]

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

You can also put resources which you do not want to translate to file called donottranslate.xml.

Example and explanation: http://tools.android.com/recent/non-translatablestrings

You are attempting to attach an event listener function before the element is loaded. Place fun() inside an onload event listener function. Call f1() within this function, as the onclick attribute will be ignored.

function f1() {
    alert("f1 called");
    //form validation that recalls the page showing with supplied inputs.    
}
window.onload = function() {
    document.getElementById("Save").onclick = function fun() {
        alert("hello");
        f1();
        //validation code to see State field is mandatory.  
    }
}

JSFiddle

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

You can do what you want if you use an iterator object to go over the elements in your set. You can remove them on the go an it's ok. However removing them while in a for loop (either "standard", of the for each kind) will get you in trouble:

Set<Integer> set = new TreeSet<Integer>();
    set.add(1);
    set.add(2);
    set.add(3);

    //good way:
    Iterator<Integer> iterator = set.iterator();
    while(iterator.hasNext()) {
        Integer setElement = iterator.next();
        if(setElement==2) {
            iterator.remove();
        }
    }

    //bad way:
    for(Integer setElement:set) {
        if(setElement==2) {
            //might work or might throw exception, Java calls it indefined behaviour:
            set.remove(setElement);
        } 
    }

As per @mrgloom's comment, here are more details as to why the "bad" way described above is, well... bad :

Without getting into too much details about how Java implements this, at a high level, we can say that the "bad" way is bad because it is clearly stipulated as such in the Java docs:

https://docs.oracle.com/javase/8/docs/api/java/util/ConcurrentModificationException.html

stipulate, amongst others, that (emphasis mine):

"For example, it is not generally permissible for one thread to modify a Collection while another thread is iterating over it. In general, the results of the iteration are undefined under these circumstances. Some Iterator implementations (including those of all the general purpose collection implementations provided by the JRE) may choose to throw this exception if this behavior is detected" (...)

"Note that this exception does not always indicate that an object has been concurrently modified by a different thread. If a single thread issues a sequence of method invocations that violates the contract of an object, the object may throw this exception. For example, if a thread modifies a collection directly while it is iterating over the collection with a fail-fast iterator, the iterator will throw this exception."

To go more into details: an object that can be used in a forEach loop needs to implement the "java.lang.Iterable" interface (javadoc here). This produces an Iterator (via the "Iterator" method found in this interface), which is instantiated on demand, and will contain internally a reference to the Iterable object from which it was created. However, when an Iterable object is used in a forEach loop, the instance of this iterator is hidden to the user (you cannot access it yourself in any way).

This, coupled with the fact that an Iterator is pretty stateful, i.e. in order to do its magic and have coherent responses for its "next" and "hasNext" methods it needs that the backing object is not changed by something else than the iterator itself while it's iterating, makes it so that it will throw an exception as soon as it detects that something changed in the backing object while it is iterating over it.

Java calls this "fail-fast" iteration: i.e. there are some actions, usually those that modify an Iterable instance (while an Iterator is iterating over it). The "fail" part of the "fail-fast" notion refers to the ability of an Iterator to detect when such "fail" actions happen. The "fast" part of the "fail-fast" (and, which in my opinion should be called "best-effort-fast"), will terminate the iteration via ConcurrentModificationException as soon as it can detect that a "fail" action has happen.

imwrite(A,filename) writes image data A to the file specified by filename, inferring the file format from the extension

I've created a version by using just a click event on the elements loaded and passing the value of the selection into the function "getSelection" and updating the model.

In your template:

<ul>
     <li *ngFor="let p of price"><input type="radio" name="price"      (click)="getValue(price.value)" value="{{p}}" #price> {{p}} 
     </li>
</ul>

Your class:

export class App {

  price:string;

  price = ["1000", "2000", "3000"];

  constructor() {   }

  model = new SomeData(this.price);

  getValue(price){
    this.model.price = price;
  }
}

See example: https://plnkr.co/edit/2Muje8yvWZVL9OXqG0pW?p=info

out has gotten a new more succint syntax in C#7 https://docs.microsoft.com/en-us/dotnet/articles/csharp/whats-new/csharp-7#more-expression-bodied-members and even more exciting is the C#7 tuple enhancements that are a more elegant choice than using ref and out IMHO.

In order for Webpack to return the correct asset paths, you need to use require('./relative/path/to/file.jpg'), which will get processed by file-loader and returns the resolved URL.

computed: {
  iconUrl () {
    return require('./assets/img.png')
    // The path could be '../assets/img.png', etc., which depends on where your vue file is
  }
}

See VueJS templates - Handling Static Assets

If you decorate the User class with the XmlType to match the required capitalization:

[XmlType("user")]
public class User
{
   ...
}

Then the XmlRootAttribute on the XmlSerializer ctor can provide the desired root and allow direct reading into List<>:

    // e.g. my test to create a file
    using (var writer = new FileStream("users.xml", FileMode.Create))
    {
        XmlSerializer ser = new XmlSerializer(typeof(List<User>),  
            new XmlRootAttribute("user_list"));
        List<User> list = new List<User>();
        list.Add(new User { Id = 1, Name = "Joe" });
        list.Add(new User { Id = 2, Name = "John" });
        list.Add(new User { Id = 3, Name = "June" });
        ser.Serialize(writer, list);
    }

...

Background You never ... really ... need to know the user's password. You just want to verify an incoming user knows the password for an account.

Hash It: Store user passwords hashed (one-way encryption) via a strong hash function. A search for "c# encrypt passwords" gives a load of examples.

See the online SHA1 hash creator for an idea of what a hash function produces (But don't use SHA1 as a hash function, use something stronger such as SHA256).

Now, a hashed passwords means that you (and database thieves) shouldn't be able to reverse that hash back into the original password.

How to use it: But, you say, how do I use this mashed up password stored in the database?

When the user logs in, they'll hand you the username and the password (in its original text) You just use the same hash code to hash that typed-in password to get the stored version.

So, compare the two hashed passwords (database hash for username and the typed-in & hashed password). You can tell if "what they typed in" matched "what the original user entered for their password" by comparing their hashes.

Extra credit:

Question: If I had your database, then couldn't I just take a cracker like John the Ripper and start making hashes until I find matches to your stored, hashed passwords? (since users pick short, dictionary words anyway ... it should be easy)

Answer: Yes ... yes they can.

So, you should 'salt' your passwords. See the Wikipedia article on salt

See "How to hash data with salt" C# example (archived)

There is also a convenient shortcut to get all elements of the array starting with specified index. For example "${A[@]:1}" would be the "tail" of the array, that is the array without its first element.

version=4.7.1
A=( ${version//\./ } )
echo "${A[@]}"    # 4 7 1
B=( "${A[@]:1}" )
echo "${B[@]}"    # 7 1

Try this:

select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;

Thank you all! i managed to do what i wanted :D http://jsfiddle.net/Tfc9j/42/ here take a look

i wanted to have the opacity of an outer div to be different from the opacity of the internal div and that change with a click somwewhere ;) Thanks!

The variable pCv is of type VARCHAR2 so when you concat the insert you aren't putting it inside single quotes:

 EXECUTE IMMEDIATE  'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('''||pCv||''', '||pSup||', '||pIdM||')';

Additionally the error ORA-06512 raise when you are trying to insert a value too large in a column. Check the definiton of the table M_pNum_GR and the parameters that you are sending. Just for clarify if you try to insert the value 100 on a NUMERIC(2) field the error will raise.

it seems the old's version's of jquery ui don't support select event anymore.

This code will work with new versions:

$('.selector').tabs({
                    activate: function(event ,ui){
                        //console.log(event);
                        console.log(ui.newTab.index());
                    }
});

First you need to create package:

com.myCompany.executabe (src > right click > new > package).

Follow these steps to move the Java files to your new package.

1. Select the Java files
2. Right click
3. Refactor
4. Move
5. Select your preferred package

import UIKit

class BorderImage: UIImageView {

    override func awakeFromNib() {
        self.layoutIfNeeded()
        layer.cornerRadius = self.frame.height / 10.0
        layer.masksToBounds = true
    }
}

Based on @DCDC's answer

You'll find the answer to your question in the help page for ?axis.

Here is one of the help page examples, modified with your data:

Option 1: use xaxp to define the axis labels

plot(x,y, xaxt="n")
axis(1, xaxp=c(10, 200, 19), las=2)

Option 2: Use at and seq() to define the labels:

plot(x,y, xaxt="n")
axis(1, at = seq(10, 200, by = 10), las=2)

Both these options yield the same graphic:

PS. Since you have a large number of labels, you'll have to use additional arguments to get the text to fit in the plot. I use las to rotate the labels.

I encountered this problem today and eventually I realize it was the comment on the line before the mysql dll's that was causing the problem.

This is what you should have in php.ini by default for PHP 5.5.16:

;extension=php_exif.dll       Must be after mbstring as it depends on it
;extension=php_mysql.dll
;extension=php_mysqli.dll

Besides removing the semi-colons, you also need to delete the line of comment that came after php_exif.dll. This leaves you with

extension=php_exif.dll      
extension=php_mysql.dll
extension=php_mysqli.dll

This solves the problem in my case.

Using io.Copy

package main

import (
    "io"
    "log"
    "os"
)

func main () {
    // open files r and w
    r, err := os.Open("input.txt")
    if err != nil {
        panic(err)
    }
    defer r.Close()

    w, err := os.Create("output.txt")
    if err != nil {
        panic(err)
    }
    defer w.Close()

    // do the actual work
    n, err := io.Copy(w, r)
    if err != nil {
        panic(err)
    }
    log.Printf("Copied %v bytes\n", n)
}

If you don't feel like reinventing the wheel, the io.Copy and io.CopyN may serve you well. If you check the source of the io.Copy function, it is nothing but one of the Mostafa's solutions (the 'basic' one, actually) packaged in the Go library. They are using a significantly larger buffer than he is, though.

implementation androidx.recyclerview:recyclerview:.... It is advised to update to the androidx libraries which are here:

The layout file Widget XML tag then must be updated to: androidx.recyclerview.widget.RecyclerView

In case you face the problem using TCPServer or SimpleHTTPServer, override SocketServer.TCPServer.allow_reuse_address (python 2.7.x) or socketserver.TCPServer.allow_reuse_address (python 3.x) attribute

class MyServer(SocketServer.TCPServer):
    allow_reuse_address = True

server = MyServer((HOST, PORT), MyHandler)
server.serve_forever()

With Protractor, you can use the following approach

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain newPageName
browser.wait(EC.urlContains('newPageName'), 10000);

So your code will look something like,

emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');

btnLoginEl.click();

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain efg
ptor.wait(EC.urlContains('efg'), 10000);

expect(ptor.getCurrentUrl()).toEqual(url + 'abc#/efg');

Note: This may not mean that new page has finished loading and DOM is ready. The subsequent 'expect()' statement will ensure Protractor waits for DOM to be available for test.

Reference: Protractor ExpectedConditions

In case anyone is looking for a solution without code, I created an example to do this completely in the storyboard, using Auto Layout.

You can get it from github.

Basically, to recreate the example (for vertical scrolling):

1. Create a UIScrollView, and set its constraints.
2. Add a UIStackView to the UIScrollView
3. Set the constraints: Leading, Trailing, Top & Bottom should be equal to the ones from UIScrollView
4. Set up an equal Width constraint between the UIStackView and UIScrollView.
5. Set Axis = Vertical, Alignment = Fill, Distribution = Equal Spacing, and Spacing = 0 on the UIStackView
6. Add a number of UIViews to the UIStackView
7. Run

Exchange Width for Height in step 4, and set Axis = Horizontal in step 5, to get a horizontal UIStackView.

func scrollToTop() {
        NSIndexPath *topItem = [NSIndexPath indexPathForItem:0 inSection:0];
        [tableView scrollToRowAtIndexPath:topItem atScrollPosition:UITableViewScrollPositionTop animated:YES];
}

call this function wherever you want UITableView scroll to top

'raw string' means it is stored as it appears. For example, '\' is just a backslash instead of an escaping.

Assuming headers are on the first row of the sheet starting at A1, and you know how many of them there are, this was my solution:

$header = array(
    'Header 1',
    'Header 2'
);

$objPHPExcel = new PHPExcel();
$objPHPExcelSheet = $objPHPExcel->getSheet(0);
$objPHPExcelSheet->fromArray($header, NULL);
$first_letter = PHPExcel_Cell::stringFromColumnIndex(0);
$last_letter = PHPExcel_Cell::stringFromColumnIndex(count($header)-1);
$header_range = "{$first_letter}1:{$last_letter}1";
$objPHPExcelSheet->getStyle($header_range)->getFont()->setBold(true);

yes you need to use a having clause after the Group by clause , as the where is just to filter the data on simple parameters , but group by followed by a Having statement is the idea to group the data and filter it on basis of some aggregate function......

It's maybe better to state this difference by the Mutability / Immutability notion that is the correct paradigm of values and instances changeability in Objects space which is larger than the only "constant / variable" usual notions. And furthermore this is closer to Objective C approach.

2 data types: value type and reference type.

In the context of Value Types:

'let' defines a constant value (immutable). 'var' defines a changeable value (mutable).

let aInt = 1   //< aInt is not changeable

var aInt = 1   //< aInt can be changed

In the context of Reference Types:

The label of a data is not the value but the reference to a value.

if aPerson = Person(name:Foo, first:Bar)

aPerson doesn't contain the Data of this person but the reference to the data of this Person.

let aPerson = Person(name:Foo, first:Bar)
               //< data of aPerson are changeable, not the reference

var aPerson = Person(name:Foo, first:Bar)
               //< both reference and data are changeable.

eg:

var aPersonA = Person(name:A, first: a)
var aPersonB = Person(name:B, first: b)

aPersonA = aPersonB

aPersonA now refers to Person(name:B, first: b)

and

let aPersonA = Person(name:A, first: a)
let aPersonB = Person(name:B, first: b)

let aPersonA = aPersonB // won't compile

but

let aPersonA = Person(name:A, first: a)

aPersonA.name = "B" // will compile

Like T.J. wrote: the order is defined (at least it's sequential when your browser is about to execute any JavaScript, even if it may download the scripts in parallel somehow). However, as apparently you're having trouble, maybe you're using third-party JavaScript libraries that yield some 404 Not Found or timeout? If so, then read Best way to use Google’s hosted jQuery, but fall back to my hosted library on Google fail.

Try converting to a string and then use "%4.4s" as the format specifier. This makes it a fixed width format.

Configure XCode project settings, it can solve your problem.

Runtime rt = Runtime.getRuntime();
rt.maxMemory()

value is b

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
am.getMemoryClass()

value is MB

$('input:radio[name="postage"]').change(function(){
    if($(this).val() === 'Yes'){
       // append stuff
    }
});

This will listen for a change event on the radio buttons. At the time the user clicks Yes, the event will fire and you will be able to append anything you like to the DOM.

I have created an illustration that explains better than words, in my opinion:

I had the same requirements and finally this Map converter worked for me. It is the best plugin for any map generation.

I'd certainly look to TomEE since the idea behind is to keep Tomcat bringing all the JavaEE 6 integration missing by default. That's a kind of very good compromise

Actually, in Bootstrap 4.0.0-Beta (as of October 2017) the input element isn't referenced by input[type="text"], all Bootstrap 4 properties for the input element are actually form based.

So it's using the .form-control:focus styles. The appropriate code for the "on focus" highlighting of an input element is the following:

.form-control:focus {
  color: #495057;
  background-color: #fff;
  border-color: #80bdff;
  outline: none;
}

Pretty easy to implement, just change the border-color property.

This is old thread but answer because if useful to anyone.

Step 1. Your Db Storage Engine set to InnoDB

Step 2. Create Primary Table

here customer is primary table and customer_id is primary key

Step 3. create foreign key table and give index

here we have customer_addresses as related table and store customer addresses, so here customer_id relation with customer table

we can select index directly when create table as below

If you forgot to give index when create a table, then you can give index from the structure tab of table as below.

Step 4. Once index give to the field, Go to structure tab and click on Relation View as shown in below pic

Step 5. Now select the ON DELETE and ON UPDATE what you want to do, Select column from current table, select DB (SAME DB), select relation table and primary key from that table as shown in below pic and Save it

Now check if relation are give successfully, go to foreign table data list and click on foreign key value, you will redirect to primary table record, then relation made successfully.

If you want to cut a string for a specifited length and add dots use

// Length to cut
var lengthToCut = 20;

// Sample text
var text = "The quick brown fox jumps over the lazy dog";

// We are getting 50 letters (0-50) from sample text
var cutted = text.substr(0, lengthToCut );
document.write(cutted+"...");

Or if you want to cut not by length but with words count use:

// Number of words to cut
var wordsToCut = 3;

// Sample text
var text = "The quick brown fox jumps over the lazy dog";

// We are splitting sample text in array of words
var wordsArray = text.split(" ");

// This will keep our generated text
var cutted = "";
for(i = 0; i < wordsToCut; i++)
 cutted += wordsArray[i] + " "; // Add to cutted word with space

document.write(cutted+"...");

Good luck...

The element.style property lets you know only the CSS properties that were defined as inline in that element (programmatically, or defined in the style attribute of the element), you should get the computed style.

Is not so easy to do it in a cross-browser way, IE has its own way, through the element.currentStyle property, and the DOM Level 2 standard way, implemented by other browsers is through the document.defaultView.getComputedStyle method.

The two ways have differences, for example, the IE element.currentStyle property expect that you access the CSS property names composed of two or more words in camelCase (e.g. maxHeight, fontSize, backgroundColor, etc), the standard way expects the properties with the words separated with dashes (e.g. max-height, font-size, background-color, etc). ......

function getStyle(el, styleProp) {
    var value, defaultView = (el.ownerDocument || document).defaultView;
    // W3C standard way:
    if (defaultView && defaultView.getComputedStyle) {
        // sanitize property name to css notation
        // (hyphen separated words eg. font-Size)
        styleProp = styleProp.replace(/([A-Z])/g, "-$1").toLowerCase();
        return defaultView.getComputedStyle(el, null).getPropertyValue(styleProp);
    } else if (el.currentStyle) { // IE
        // sanitize property name to camelCase
        styleProp = styleProp.replace(/\-(\w)/g, function(str, letter) {
            return letter.toUpperCase();
        });
        value = el.currentStyle[styleProp];
        // convert other units to pixels on IE
        if (/^\d+(em|pt|%|ex)?$/i.test(value)) { 
            return (function(value) {
                var oldLeft = el.style.left, oldRsLeft = el.runtimeStyle.left;
                el.runtimeStyle.left = el.currentStyle.left;
                el.style.left = value || 0;
                value = el.style.pixelLeft + "px";
                el.style.left = oldLeft;
                el.runtimeStyle.left = oldRsLeft;
                return value;
            })(value);
        }
        return value;
    }
}

Generally if something works on various computers but fails on only one computer, then there's something wrong with that computer. Here are a few things to check:
(1) Are you running the same stuff on that computer -- OS including patches, etc.
(2) Does the computer report problems? Where to look depends on the OS, but it looks like you're using linux, so check syslog
(3) Run hardware diagnostics, e.g. the ones recommended here. Start with memory and disk checks in particular.

If you can't turn up any issues, then search for a similar issue in the bug parade for whichever VM you're using. Unfortunately if you're already on the latest version of the VM, then you won't necessarily find a fix.

Finally, one more option is simply to try another VM -- e.g. OpenJDK or JRockit, instead of Oracle's standard.

If you really have:

var s = ['{"Select":"11", "PhotoCount":"12"}','{"Select":"21", "PhotoCount":"22"}'];

then simply:

var objs = $.map(s, $.parseJSON);

Here's a demo.

If you see your error message it says

Building in workspace /var/lib/jenkins/workspace/AutoScript

and as per your comments you have put urltest.sh in

/var/lib/jenkins

Hence Jenkins is not able to find the file. In your build step do this thing, it will work

cd             # which will point to /var/lib/jenkins
./urltest.sh   # it will run your script

If it still fails try to chown the file as jenkin user may not have file permission, but I think if you do above step you will be able to run.

According to other answers I am adding the parallel stages scenario:

    agent any
    stages {
        stage('some parallel stage') {
            parallel {
                stage('parallel stage 1') {
                    when {
                      expression { ENV == "something" }
                    }
                    steps {
                        echo 'something'
                    }
                }
                stage('parallel stage 2') {
                    steps {
                        echo 'something'
                    }
                }
            }
        }
    }

hey guys i think what you are looking for is this one using select command. With this you can specify a RANGE GREATER THAN(>) OR LESSER THAN(<) IN MySQL WITH THIS:::::

select* from <**TABLE NAME**> where year(**COLUMN NAME**) > **DATE** OR YEAR(COLUMN NAME )< **DATE**;

FOR EXAMPLE:

select name, BIRTH from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+------------+
| name     | BIRTH      |
+----------+------------+
| bowser   | 1979-09-11 |
| chirpy   | 1998-09-11 |
| whistler | 1999-09-09 |
+----------+------------+

FOR SIMPLE RANGE LIKE USE ONLY GREATER THAN / LESSER THAN

mysql> select COLUMN NAME from <TABLE NAME> where year(COLUMN NAME)> 1996;

FOR EXAMPLE mysql>

select name from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+
| name     |
+----------+
| bowser   |
| chirpy   |
| whistler |
+----------+

Be careful of what you want to convert. JPG doesn't support alpha-transparency while PNG does. You will lose that information.

To convert, you may use the following function:

// Quality is a number between 0 (best compression) and 100 (best quality)
function png2jpg($originalFile, $outputFile, $quality) {
    $image = imagecreatefrompng($originalFile);
    imagejpeg($image, $outputFile, $quality);
    imagedestroy($image);
}

This function uses the imagecreatefrompng() and the imagejpeg() functions from the GD library.

setting the overflow should take care of it, but you need to set the height of Content also. If the height attribute is not set, the div will grow vertically as tall as it needs to, and scrollbars wont be needed.

See Example: http://jsfiddle.net/ftkbL/1/

You need to access the underlying buffer:

printf("%s\n", someString.c_str());

Or better use cout << someString << endl; (you need to #include <iostream> to use cout)

Additionally you might want to import the std namespace using using namespace std; or prefix both string and cout with std::.

Updated 5 September 2010

Seeing as everyone seems to get directed here for this issue, I'm adding my answer to a similar question, which contains the same code as this answer but with full background for those who are interested:

IE's document.selection.createRange doesn't include leading or trailing blank lines

To account for trailing line breaks is tricky in IE, and I haven't seen any solution that does this correctly, including any other answers to this question. It is possible, however, using the following function, which will return you the start and end of the selection (which are the same in the case of a caret) within a <textarea> or text <input>.

Note that the textarea must have focus for this function to work properly in IE. If in doubt, call the textarea's focus() method first.

function getInputSelection(el) {
    var start = 0, end = 0, normalizedValue, range,
        textInputRange, len, endRange;

    if (typeof el.selectionStart == "number" && typeof el.selectionEnd == "number") {
        start = el.selectionStart;
        end = el.selectionEnd;
    } else {
        range = document.selection.createRange();

        if (range && range.parentElement() == el) {
            len = el.value.length;
            normalizedValue = el.value.replace(/\r\n/g, "\n");

            // Create a working TextRange that lives only in the input
            textInputRange = el.createTextRange();
            textInputRange.moveToBookmark(range.getBookmark());

            // Check if the start and end of the selection are at the very end
            // of the input, since moveStart/moveEnd doesn't return what we want
            // in those cases
            endRange = el.createTextRange();
            endRange.collapse(false);

            if (textInputRange.compareEndPoints("StartToEnd", endRange) > -1) {
                start = end = len;
            } else {
                start = -textInputRange.moveStart("character", -len);
                start += normalizedValue.slice(0, start).split("\n").length - 1;

                if (textInputRange.compareEndPoints("EndToEnd", endRange) > -1) {
                    end = len;
                } else {
                    end = -textInputRange.moveEnd("character", -len);
                    end += normalizedValue.slice(0, end).split("\n").length - 1;
                }
            }
        }
    }

    return {
        start: start,
        end: end
    };
}

IUSR permissions use on a folder if not under inetpub/wwwroot will be solution for some.

Nuget Gallery provides a GUI similar to the full Visual Studio. See below.

How To Use:

1. Install Nuget Gallery from extension marketplace.
2. Launch from the menu bar View > Command Palette or ??P (Ctrl+Shift+P on Windows and Linux). Type Nuget: Open Gallery.
3. The GUI above is displayed. You can filter just like in regular Visual Studio.
4. Make sure the .csproj file checkbox is selected, select version from dropdown, and click install button.

UPDATE

Earlier versions, as noted in the comments, had an issue where the .csproj checkbox was not visible when a package in the csproj file was missing a version number like below.

<PackageReference Include="Microsoft.AspNetCore.App" />

This has been fixed in newer versions of the extension so if you have an older version with this issue, please update it to the latest version.

If path is not hardcoded in any script then your websites should work seamlessly.

(?<=\[).+?(?=\])

Will capture content without brackets

• (?<=\[) - positive lookbehind for [

• .*? - non greedy match for the content

• (?=\]) - positive lookahead for ]

EDIT: for nested brackets the below regex should work:

(\[(?:\[??[^\[]*?\]))

Answering after long time but hope this will help somebody who looking for a simple solution and modern newbies.

Now we can achieve this using multiple libraries like lodash, underscore, etc. (These becomes part of the project nowadays due to simplicity, multiple features and high usage)

You can use intersection from lodash library.

_.intersection(['2-1', '1'], ['2-2', '3-1', '2-1']); 
// => ['2-1']

This will work for any data type..

If you want a condition to show elements, you can use something like this.

renderButton() {
    if (this.state.loading) {
        return <Spinner size="small" spinnerStyle={styles.spinnerStyle} />;
    }

    return (
        <Button onPress={this.onButtonPress.bind(this)}>
            Log In
        </Button>
    );
}

Then call the helping method inside render function.

<View style={styles.buttonStyle}>
      {this.renderButton()}
</View>

Or you can use another way of condition inside return.

{this.props.hasImage ? <element1> : <element2>}

From the code point of view, you need to implement the SensorListener:

public class ShakeActivity extends Activity implements SensorListener

You will need to acquire a SensorManager:

sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE);

And register this sensor with desired flags:

sensorMgr.registerListener(this,
SensorManager.SENSOR_ACCELEROMETER,
SensorManager.SENSOR_DELAY_GAME);

In your onSensorChange() method, you determine whether it’s a shake or not:

public void onSensorChanged(int sensor, float[] values) {
  if (sensor == SensorManager.SENSOR_ACCELEROMETER) {
    long curTime = System.currentTimeMillis();
    // only allow one update every 100ms.
    if ((curTime - lastUpdate) > 100) {
      long diffTime = (curTime - lastUpdate);
      lastUpdate = curTime;

      x = values[SensorManager.DATA_X];
      y = values[SensorManager.DATA_Y];
      z = values[SensorManager.DATA_Z];

      float speed = Math.abs(x+y+z - last_x - last_y - last_z) / diffTime * 10000;

      if (speed > SHAKE_THRESHOLD) {
        Log.d("sensor", "shake detected w/ speed: " + speed);
        Toast.makeText(this, "shake detected w/ speed: " + speed, Toast.LENGTH_SHORT).show();
      }
      last_x = x;
      last_y = y;
      last_z = z;
    }
  }
}

The shake threshold is defined as:

private static final int SHAKE_THRESHOLD = 800;

There are some other methods too, to detect shake motion. look at this link.(If that link does not work or link is dead, look at this web archive.).

Have a look at this example for android shake detect listener.

Note: SensorListener is deprecated. we can use SensorEventListener instead. Here is a quick example using SensorEventListener.

Thanks.

The problem was caused because the page was an intranet site, & IE had compatibility mode set to default for this. IE11 does support addEventListener()

You need to add:

 #include <cstdlib>

in order for the compiler to see the prototype for system().

One can import the package then consult its help

import statsmodels
help(sm)

At the very bottom of the help there is a section FILE that indicates where this package was installed.

This solution was tested with at least matplotlib (3.1.2) and statsmodels (0.11.1) (python 3.8.2).

Look at ?par for the various graphics parameters.

In general cex controls size, col controls colour. If you want to control the colour of a label, the par is col.lab, the colour of the axis annotations col.axis, the colour of the main text, col.main etc. The names are quite intuitive, once you know where to begin.

For example

x <- 1:10
y <- 1:10

plot(x , y,xlab="x axis", ylab="y axis",  pch=19, col.axis = 'blue', col.lab = 'red', cex.axis = 1.5, cex.lab = 2)

If you need to change the colour / style of the surrounding box and axis lines, then look at ?axis or ?box, and you will find that you will be using the same parameter names within calls to box and axis.

You have a lot of control to make things however you wish.

eg

plot(x , y,xlab="x axis", ylab="y axis",  pch=19,  cex.lab = 2, axes = F,col.lab = 'red')
box(col = 'lightblue')
axis(1, col = 'blue', col.axis = 'purple', col.ticks = 'darkred', cex.axis = 1.5, font = 2, family = 'serif')
axis(2, col = 'maroon', col.axis = 'pink', col.ticks = 'limegreen', cex.axis = 0.9, font =3, family = 'mono')

Which is seriously ugly, but shows part of what you can control

Sort the array just as before, but print the elements out in reverse order, using a loop that counts down rather than counting up.

Also, move the sort out of the loop - you are currently sorting the array over and over again when you only need to sort it once.

                Arrays.sort(arr);
                for(int i = 0; i < arr.length; i++){
                    //Arrays.sort(arr); // not here
                    System.out.print( " " +arr[i]);
                }
                for(int i = arr.length-1; i >= 0; i--){
                    //Arrays.sort(arr); // not here
                    System.out.print( " " +arr[i]);
                }

I have used this technique successfully in the past:

Using Excel to generate Inserts for SQL Server

(...) Skip a column (or use it for notes) and then type something like the following formula in it:

="insert into tblyourtablename (yourkeyID_pk, intmine, strval) values ("&A4&", "&B4&", N'"&C4&"')"

Now you’ve got your insert statement for a table with your primary key (PK), an integer and a unicode string. (...)

Might be useful to some : check for

pointer-events: none;

In the CSS. It prevents clicks from being caught by JS. I think it's relevant because the CSS might be the last place you'd look into in this kind of situation.

you must change php_admin_value max_execution_time in your Alias config (\XAMPP\alias\phpmyadmin.conf)

answer is here: WAMPServer phpMyadmin Maximum execution time of 360 seconds exceeded

Use Google Sheets instead of Excel - this feature is built in, so you can use regex right from the find and replace dialog.

To answer your question:

1. Copy the data from Excel and paste into Google Sheets
2. Use the find and replace dialog with regex
3. Copy the data from Google Sheets and paste back into Excel

Another solution not using IFS and still preserving the spaces:

$ var="a bc,def,ghij"
$ while read line; do echo line="$line"; done < <(echo "$var" | tr ',' '\n')
line=a bc
line=def
line=ghij

You just write this script. use input element for this.

$("input").val("valuesgoeshere"); 

or by id="fsd" you write this code.

$("input").val(document.getElementById("fsd").innerHTML);

Actually you can use a switch statement with Strings in Java...unfortunately this is a new feature of Java 7, and most people are not using Java 7 yet because it's so new.

Probably to guarantee that public webservices will be unique.

It always makes me think of delicious deep fried treats...

This will do what you want:

select * 
  from orders_products 
       INNER JOIN orders 
          ON orders_products.orders_id = orders.orders_id
 where products_id in (180, 181);

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

assertTrue()/assertFalse() : to use only to assert boolean result returned

assertTrue(Iterables.elementsEqual(argumentComponents, returnedComponents));

You want to use Assert.assertTrue() or Assert.assertFalse() as the method under test returns a boolean value.
As the method returns a specific thing such as a List that should contain some expected elements, asserting with assertTrue() in this way : Assert.assertTrue(myActualList.containsAll(myExpectedList) is an anti pattern.
It makes the assertion easy to write but as the test fails, it also makes it hard to debug because the test runner will only say to you something like :

expected true but actual is false

Assert.assertEquals(Object, Object) in JUnit4 or Assertions.assertIterableEquals(Iterable, Iterable) in JUnit 5 : to use only as both equals() and toString() are overrided for the classes (and deeply) of the compared objects

It matters because the equality test in the assertion relies on equals() and the test failure message relies on toString() of the compared objects.
As String overrides both equals() and toString(), it is perfectly valid to assert the List<String> with assertEquals(Object,Object). And about this matter : you have to override equals() in a class because it makes sense in terms of object equality, not only to make assertions easier in a test with JUnit.
To make assertions easier you have other ways (that you can see in the next points of the answer).

Is Guava a way to perform/build unit test assertions ?

Is Google Guava Iterables.elementsEqual() the best way, provided I have the library in my build path, to compare those two lists?

No it is not. Guava is not an library to write unit test assertions.
You don't need it to write most (all I think) of unit tests.

What's the canonical way to compare lists for unit tests?

As a good practice I favor assertion/matcher libraries.

I cannot encourage JUnit to perform specific assertions because this provides really too few and limited features : it performs only an assertion with a deep equals.
Sometimes you want to allow any order in the elements, sometimes you want to allow that any elements of the expected match with the actual, and so for...

So using a unit test assertion/matcher library such as Hamcrest or AssertJ is the correct way.
The actual answer provides a Hamcrest solution. Here is a AssertJ solution.

org.assertj.core.api.ListAssert.containsExactly() is what you need : it verifies that the actual group contains exactly the given values and nothing else, in order as stated :

Verifies that the actual group contains exactly the given values and nothing else, in order.

Your test could look like :

import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Test;

@Test
void ofComponent_AssertJ() throws Exception {
   MyObject myObject = MyObject.ofComponents("One", "Two", "Three");
   Assertions.assertThat(myObject.getComponents())
             .containsExactly("One", "Two", "Three");
}

A AssertJ good point is that declaring a List as expected is needless : it makes the assertion straighter and the code more readable :

Assertions.assertThat(myObject.getComponents())
         .containsExactly("One", "Two", "Three");

And if the test fails :

// Fail : Three was not expected 
Assertions.assertThat(myObject.getComponents())
          .containsExactly("One", "Two");

you get a very clear message such as :

java.lang.AssertionError:

Expecting:

<["One", "Two", "Three"]>

to contain exactly (and in same order):

<["One", "Two"]>

but some elements were not expected:

<["Three"]>

Assertion/matcher libraries are a must because these will really further

Suppose that MyObject doesn't store Strings but Foos instances such as :

public class MyFooObject {

    private List<Foo> values;
    @SafeVarargs
    public static MyFooObject ofComponents(Foo... values) {
        // ...
    }

    public List<Foo> getComponents(){
        return new ArrayList<>(values);
    }
}

That is a very common need. With AssertJ the assertion is still simple to write. Better you can assert that the list content are equal even if the class of the elements doesn't override equals()/hashCode() while JUnit ways require that :

import org.assertj.core.api.Assertions;
import static org.assertj.core.groups.Tuple.tuple;
import org.junit.jupiter.api.Test;

@Test
void ofComponent() throws Exception {
    MyFooObject myObject = MyFooObject.ofComponents(new Foo(1, "One"), new Foo(2, "Two"), new Foo(3, "Three"));

    Assertions.assertThat(myObject.getComponents())
              .extracting(Foo::getId, Foo::getName)
              .containsExactly(tuple(1, "One"),
                               tuple(2, "Two"),
                               tuple(3, "Three"));
}

Install playsound package using :

pip install playsound

Usage:

from playsound import playsound

(in answer to the second question) By only using a sign bit (and not 2's complement), you can end up with -0. Not very pretty.

// rename the .json file to .js and keep in src folder

Declare the json object as a variable

var customData = {
   "key":"value"

Export it using module.exports

module.exports = customData;

From the component that needs it, make sure to back out two folders deep

import customData from '../customData';

You are doing it wrong since you try to map WebForms in the MVC application.

There are no server side controlls in MVC. Only the View and the Controller on the back-end. You send the data from server to the client by means of initialization of the View with your model.

This is happening on the HTTP GET request to your resource.

[HttpGet]
public ActionResult Home() 
{
  var model = new HomeModel { Greeatings = "Hi" };
  return View(model);
}

You send data from client to server by means of posting data to server. To make that happen, you create a form inside your view and [HttpPost] handler in your controller.

// View

@using (Html.BeginForm()) {
  @Html.TextBoxFor(m => m.Name)
  @Html.TextBoxFor(m => m.Password)
}

// Controller

[HttpPost]
public ActionResult Home(LoginModel model) 
{
  // do auth.. and stuff
  return Redirect();
}

Code:

using System.Net.Mail

new SmtpClient("smtp.server.com", 25).send("[email protected]", 
                                           "[email protected]", 
                                           "subject", 
                                           "body");

Mass Emails:

SMTP servers usually have a limit on the number of connection hat can handle at once, if you try to send hundreds of emails you application may appear unresponsive.

Solutions:

• If you are building a WinForm then use a BackgroundWorker to process the queue.
• If you are using IIS SMTP server or a SMTP server that has an outbox folder then you can use SmtpClient().PickupDirectoryLocation = "c:/smtp/outboxFolder"; This will keep your system responsive.
• If you are not using a local SMTP server than you could build a system service to use Filewatcher to monitor a forlder than will then process any emails you drop in there.

There is already an AI implementation for this game here. Excerpt from README:

The algorithm is iterative deepening depth first alpha-beta search. The evaluation function tries to keep the rows and columns monotonic (either all decreasing or increasing) while minimizing the number of tiles on the grid.

There is also a discussion on Hacker News about this algorithm that you may find useful.

A more thorough solution

The core of this is the replace call. So far, I don't think any of the proposed solutions handle all of the following cases:

• Integers: 1000 => '1,000'
• Strings: '1000' => '1,000'
• For strings:
  • Preserves zeros after decimal: 10000.00 => '10,000.00'
  • Discards leading zeros before decimal: '01000.00 => '1,000.00'
  • Does not add commas after decimal: '1000.00000' => '1,000.00000'
  • Preserves leading - or +: '-1000.0000' => '-1,000.000'
  • Returns, unmodified, strings containing non-digits: '1000k' => '1000k'

The following function does all of the above.

addCommas = function(input){
  // If the regex doesn't match, `replace` returns the string unmodified
  return (input.toString()).replace(
    // Each parentheses group (or 'capture') in this regex becomes an argument 
    // to the function; in this case, every argument after 'match'
    /^([-+]?)(0?)(\d+)(.?)(\d+)$/g, function(match, sign, zeros, before, decimal, after) {

      // Less obtrusive than adding 'reverse' method on all strings
      var reverseString = function(string) { return string.split('').reverse().join(''); };

      // Insert commas every three characters from the right
      var insertCommas  = function(string) { 

        // Reverse, because it's easier to do things from the left
        var reversed           = reverseString(string);

        // Add commas every three characters
        var reversedWithCommas = reversed.match(/.{1,3}/g).join(',');

        // Reverse again (back to normal)
        return reverseString(reversedWithCommas);
      };

      // If there was no decimal, the last capture grabs the final digit, so
      // we have to put it back together with the 'before' substring
      return sign + (decimal ? insertCommas(before) + decimal + after : insertCommas(before + after));
    }
  );
};

You could use it in a jQuery plugin like this:

$.fn.addCommas = function() {
  $(this).each(function(){
    $(this).text(addCommas($(this).text()));
  });
};

In order to get rid of duplicates, you can group by drinks.id. But that way you'll get only one photo for each drinks.id (which photo you'll get depends on database internal implementation).

Though it is not documented, in case of MySQL, you'll get the photo with lowest id (in my experience I've never seen other behavior).

SELECT name, price, photo 
FROM drinks, drinks_photos 
WHERE drinks.id = drinks_id
GROUP BY drinks.id

One important fact about NVIDIA drivers that is not very well known is that its built is done by DKMS. This allows automatic rebuild in case of kernel upgrade, this happens on system startup. Because of that, it's quite easy to miss error messages, especially if you're working on cloud VM, or server without an additional IPMI/management interface. However, it's possible to trigger DKMS build just executing dkms autoinstall right after packages installation. If this fails then you'll have a meaningful error message about missing dependency or what so ever. If dkms autoinstall builds modules correctly you can simply load it by modprobe - there is no need to reboot the system (which is often used as a way to trigger DKMS rebuild). You can check an example here

There are two Things you can do

use

int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();

or

int noOfColumns = sh.getRow(0).getLastCellNum();

There is a fine difference between them

1. Option 1 gives the no of columns which are actually filled with contents(If the 2nd column of 10 columns is not filled you will get 9)
2. Option 2 just gives you the index of last column. Hence done 'getLastCellNum()'

You can simply use base64.urlsafe_b64decode(data) if you are trying to decode a web image. It will automatically take care of the padding.

You can use shorthand syntax as of Twig 1.12.0

{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}

chsh -s $(which zsh)

You'll be prompted for your password, but once you update your settings any new iTerm/Terminal sessions you start on that machine will default to zsh.

To add up to Louis answer:

Alternatively you can use the attribute ToolVersion="12.0" if you are using Visual Studio 2013 instead of using the ToolPath Attribute. Details visit http://msdn.microsoft.com/en-us/library/dd647548.aspx

So you are not forced to use absolute path.

If you are using Webpack 4, the answer is to use the ProvidePlugin. Their documentation specifically covers angular.js with jquery use case:

new webpack.ProvidePlugin({
  'window.jQuery': 'jquery'
});

The issue is that when using import syntax angular.js and jquery will always be imported before you have a chance to assign jquery to window.jQuery (import statements will always run first no matter where they are in the code!). This means that angular will always see window.jQuery as undefined until you use ProvidePlugin.

The answer for Swift 2.0 Alamofire 3.0 should actually look more like this:

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON
{ response in switch response.result {
                case .Success(let JSON):
                    print("Success with JSON: \(JSON)")

                    let response = JSON as! NSDictionary

                    //example if there is an id
                    let userId = response.objectForKey("id")!

                case .Failure(let error):
                    print("Request failed with error: \(error)")
                }
    }

UPDATE for Alamofire 4.0 and Swift 3.0 :

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
            .responseJSON { response in
                print(response)
//to get status code
                if let status = response.response?.statusCode {
                    switch(status){
                    case 201:
                        print("example success")
                    default:
                        print("error with response status: \(status)")
                    }
                }
//to get JSON return value
            if let result = response.result.value {
                let JSON = result as! NSDictionary
                print(JSON)
            }

        }

This worked for me:

SELECT user, time FROM 
(
    SELECT user, time FROM lms_attendance --where clause
) AS T 
WHERE (SELECT COUNT(0) FROM table WHERE user = T.user AND time > T.time) = 0
ORDER BY user ASC, time DESC

You can use psutil package:

Install

pip install psutil

Usage:

import psutil

process_name = "chrome"
pid = None

for proc in psutil.process_iter():
    if process_name in proc.name():
       pid = proc.pid

To make this work for a ForeignKey field, a few changes need to be made. Firstly, the SELECT HTML tag does not have the readonly attribute. We need to use disabled="disabled" instead. However, then the browser doesn't send any form data back for that field. So we need to set that field to not be required so that the field validates correctly. We then need to reset the value back to what it used to be so it's not set to blank.

So for foreign keys you will need to do something like:

class ItemForm(ModelForm):

    def __init__(self, *args, **kwargs):
        super(ItemForm, self).__init__(*args, **kwargs)
        instance = getattr(self, 'instance', None)
        if instance and instance.id:
            self.fields['sku'].required = False
            self.fields['sku'].widget.attrs['disabled'] = 'disabled'

    def clean_sku(self):
        # As shown in the above answer.
        instance = getattr(self, 'instance', None)
        if instance:
            return instance.sku
        else:
            return self.cleaned_data.get('sku', None)

This way the browser won't let the user change the field, and will always POST as it it was left blank. We then override the clean method to set the field's value to be what was originally in the instance.

Your example creates multiple key: value pairs if using fromkeys. If you don't want this, you can use one key and create an alias for the key. For example if you are using a register map, your key can be the register address and the alias can be register name. That way you can perform read/write operations on the correct register.

>>> mydict = {}
>>> mydict[(1,2)] = [30, 20]
>>> alias1 = (1,2)
>>> print mydict[alias1]
[30, 20]
>>> mydict[(1,3)] = [30, 30]
>>> print mydict
{(1, 2): [30, 20], (1, 3): [30, 30]}
>>> alias1 in mydict
True

There is a simpler solution to this. What you describe is the natural behavior of the & operator and can thus be done primatively:

> c(1,1,NA) & c(1,0,NA) & c(1,NA,NA)
[1]  TRUE FALSE    NA

If all are 1, then 1 is returned. If any are 0, then 0. If all are NA, then NA.

In your case, the code would be:

DF$Den<-DF$Denial1 & DF$Denial2 & DF$Denial3

In order for this to work, you will need to stop working in character and use numeric or logical types.

You can use System.IO.Path.GetFileName to do this.

E.g.,

string[] files = Directory.GetFiles(dir);
foreach(string file in files)
    Console.WriteLine(Path.GetFileName(file));

While you could use FileInfo, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFiles unless you need the additional functionality of the FileInfo class.

This fix no longer works after CTP5.

You have to do Database.SetInitializer<YourContext>(null);

Sub-pixel rendering in browsers

Sub-pixel rendering is tricky. You can't actually expect a monitor to render a less than a pixel thin line. But it's possible to provide sub-pixel dimensions. Depending on the browser they render these differently. Check this John Resig's blog post about it.

Basically if your monitor is an LCD and you're drawing vertical lines, you can easily draw a 1/3 pixel line. If your background is white, give your line colour of #f0f. To the eye this line will be 1/3 of pixel wide. Although it will be of some colour, if you'd magnify monitor, you'd see that only one segment of the whole pixel (consisting of RGB) will be dark. This is pretty much technique that's used for fine type hinting i.e. ClearType.

But horizontal lines can only be a full pixel high. That's technology limitation of LCD monitors. CRTs were even more complicated with their triangular phosphors (unless they were aperture grille type ie. Sony Trinitron) but that's a different story.

Basically providing a sub-pixel dimension and expecting it to render that way is same as expecting an integer variable to store a number of 1.2034759349. If you understand this is impossible, you should understand that monitors aren't able to render sub-pixel dimensions.

Cross browser safe style

But the way horizontal rules that blend in are usually done using colours. So if your background is for instance white (#fff) you can always make your HR very light. Like #eee.

The cross browser safe style for very light horizontal rule would be:

hr
{
    background-color: #eee;
    border: 0 none;
    color: #eee;
    height: 1px;
}

And use a CSS file instead of in-line styles. They provide a central definition for the whole site not just a particular element. It makes maintainability much better.

From websites, using Firefox, I use the CopyPlainText extension.
