First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.

If you would like to continue using the original auto-prefixed controller routing, you can simply set the value of the $namespace property within your RouteServiceProvider and update the route registrations within the boot method to use the $namespace property:

class RouteServiceProvider extends ServiceProvider
{
    /**
     * This namespace is applied to your controller routes.
     *
     * In addition, it is set as the URL generator's root namespace.
     *
     * @var string
     */
    protected $namespace = 'App\Http\Controllers';

    /**
     * Define your route model bindings, pattern filters, etc.
     *
     * @return void
     */
    public function boot()
    {
        $this->configureRateLimiting();

        $this->routes(function () {
            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/web.php'));

            Route::prefix('api')
                ->middleware('api')
                ->namespace($this->namespace)
                ->group(base_path('routes/api.php'));
    });
}

You can also download the correct chromedriver version from:

https://chromedriver.chromium.org/downloads https://chromedriver.storage.googleapis.com/index.html?path=81.0.4044.138/

This solution may help you if you know your problem is limited to Facades and you are running Laravel 5.5 or above.

Install laravel-ide-helper

composer require --dev barryvdh/laravel-ide-helper

Add this conditional statement in your AppServiceProvider to register the helper class.

public function register()
{
    if ($this->app->environment() !== 'production') {
        $this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
    }
    // ...
}

Then run php artisan ide-helper:generate to generate a file to help the IDE understand Facades. You will need to restart Visual Studio Code.

this worked for me but use wisely

happy learning :)

if you have everything correctly configured then try this:

adb reverse tcp:8081 tcp:8081

Why? "When the RN packager is running, there is an active web server accessible in your browser at 127.0.0.1:8081. It's from this server that the JS bundle for your application is served and refreshed as you make changes. Without the reverse proxy, your phone wouldn't be able to connect to that address."

There are many ways of doing it, I'm listing a few here:

1. Use SizedBox if you want to set some specific space

   Row(
     children: <Widget>[
       Text("1"),
       SizedBox(width: 50), // give it width
       Text("2"),
     ],
   )
   

   

2. Use Spacer if you want both to be as far apart as possible.

   Row(
     children: <Widget>[
       Text("1"),
       Spacer(), // use Spacer
       Text("2"),
     ],
   )
   

   

3. Use mainAxisAlignment according to your needs:

   Row(
     mainAxisAlignment: MainAxisAlignment.spaceEvenly, // use whichever suits your need
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

4. Use Wrap instead of Row and give some spacing

   Wrap(
     spacing: 100, // set spacing here
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

5. Use Wrap instead of Row and give it alignment

   Wrap(
     alignment: WrapAlignment.spaceAround, // set your alignment
     children: <Widget>[
       Text("1"),
       Text("2"),
     ],
   )
   

   

I got same problem. So I looked into the axios document. I found it. you can do it like this. this is easiest way. and super simple.

https://www.npmjs.com/package/axios#using-applicationx-www-form-urlencoded-format

var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);

You can use .then,.catch.

I was unable to find the root cause of the issue but got a workaround. I started by setting my the java home variable as such.

• vi ~/.bash_profile (this is for macs only. bash profiles are different on linux)
• type the letter i for insert and then set the JAVA_HOME variable as such
• export JAVA_HOME=/Applications/Android\Studio.app/Contents/jre/jdk/Contents/Home/
• quit the vi editor with esc then type :wq
• Restart the computer
• Voila! Your android studio projects should build without any qualms

For Angular Version 11+

Configuration

The styles and scripts options in your angular.json configuration now allow to reference a package directly:

before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]

          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","bootstrap/dist/css/bootstrap.min.css"

            ],
            "scripts": [
                       "jquery/dist/jquery.min.js",
                       "bootstrap/dist/js/bootstrap.min.js"
                       ]
          },

Angular Version 10 and below

Angular v6 Onwards

CLI projects in angular 6 onwards will be using angular.json instead of .angular-cli.json for build and project configuration.

Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs

. {
  "projects": {
    "my-project-name": {
      "projectType": "application",
      "architect": {
        "build": {
          "configurations": {
            "production": {},
            "demo": {},
            "staging": {},
          }
        },
        "serve": {},
        "extract-i18n": {},
        "test": {},
      }
    },
    "my-project-name-e2e": {}
  },
}

OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap are dependent on jQuery. So you need the jQuery JavaScript library file too.

In your angular.json add the file paths to the styles and scripts array in under build target
NOTE: Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json. As of v6 the location of the file changed to angular.json. Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash

i.e you can provide an absolute path instead of a relative path

In .angular-cli.json file Path was "../node_modules/"
In angular.json it is "node_modules/"

 "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"
               
            ],
            "scripts": ["node_modules/jquery/dist/jquery.min.js",
                       "node_modules/bootstrap/dist/js/bootstrap.min.js"]
          },

OPTION 2
Add files from CDN (Content Delivery Network) to your project CDN LINK

Open file src/index.html and insert

the <link> element at the end of the head section to include the Bootstrap CSS file
a <script> element to include jQuery at the bottom of the body section
a <script> element to include Popper.js at the bottom of the body section
a <script> element to include the Bootstrap JavaScript file at the bottom of the body section

  <!doctype html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Angular</title>
      <base href="/">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <link rel="icon" type="image/x-icon" href="favicon.ico">
      <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">
    </head>
    <body>
      <app-root>Loading...</app-root>
      <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

    </body>
    </html>

OPTION 3
Execute npm install bootstrap
In src/styles.css add the following line:

@import "~bootstrap/dist/css/bootstrap.css";

OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript

npm install --save @ng-bootstrap/ng-bootstrap

After Installation import it in your root module and register it in @NgModule imports` array

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

NOTE
ng-bootstrap requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save In your angular.json add the file paths to the styles array in under build target

   "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],

P.S Do Restart Your server

This would also work :

import 'package:http/http.dart' as http;

  sendRequest() async {

    Map data = {
       'apikey': '12345678901234567890'
    };

    var url = 'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
    http.post(url, body: data)
        .then((response) {
      print("Response status: ${response.statusCode}");
      print("Response body: ${response.body}");
    });  
  }

We have tried custom search box with the pasted snippet. This code will useful for all kind of TextFiled decoration in Flutter. Hope this snippet will helpful for others.

Container(
        margin: EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 10.0),
        child:  new Theme(
          data: new ThemeData(
           hintColor: Colors.white,
            primaryColor: Colors.white,
            primaryColorDark: Colors.white,
          ),
          child:Padding(
          padding: EdgeInsets.all(10.0),
          child: TextField(
            style: TextStyle(color: Colors.white),
            onChanged: (value) {
              filterSearchResults(value);
            },
            controller: editingController,
            decoration: InputDecoration(
                labelText: "Search",
                hintText: "Search",
                prefixIcon: Icon(Icons.search,color: Colors.white,),
                enabled: true,
                enabledBorder: OutlineInputBorder(
                  borderSide: BorderSide(color: Colors.white),
                    borderRadius: BorderRadius.all(Radius.circular(25.0))),
                border: OutlineInputBorder(
                    borderSide: const BorderSide(color: Colors.white, width: 0.0),
                    borderRadius: BorderRadius.all(Radius.circular(25.0)))),
          ),
        ),
        ),
      ),

I have the same problem, in build.gradle (Module:app) add the following line of code inside dependencies:

dependencies 
{
   ...
   compile 'com.android.support:support-annotations:27.1.1'
}

It worked for me perfectly

class MyApp2 extends StatelessWidget {

  @override
  Widget build(BuildContext context) { 
    return MaterialApp( 
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        appBarTheme: AppBarTheme(
          elevation: 0,
          color: Colors.blueAccent,
        )
      ),
      title: 'Welcome to flutter ',
      home: HomePage()
    );
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {

  int number = 0;
  void _increment(){
   setState(() {
      number ++;
   });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        backgroundColor: Colors.blueAccent,
        appBar: AppBar(
          title: Text('MyApp2'), 
          leading: Icon(Icons.menu),
          // backgroundColor: Colors.blueAccent,

          ),
        body: Container(
          decoration: BoxDecoration(
            borderRadius: BorderRadius.only(
              topLeft: Radius.circular(200.0),
              topRight: Radius.circular(200)
            ), 
            color: Colors.white,
          ),
        )
      );
  }
}

In my case the error was still there, because my system used upgraded Java. If you are using Java 10, modify the compileOptions:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_10
    targetCompatibility JavaVersion.VERSION_1_10

}

Pip 10.0.* doesn't support main.

You have to downgrade to pip 9.0.3.

Android Device Monitor was deprecated in Android Studio 3.1 and removed from Android Studio 3.2

Use Android Profiler introduced in Android Studio 3.0 to measure the cpu utilisation, network, memory etc,. To open Android Profiler: View -> Tool Windows -> Profiler.

Android Device Monitor has been replaced by some new feature which you can find here.

We have noticed that using the MediaQuery class can be a bit cumbersome, and it’s also missing a couple of key pieces of information.

Here We have a small Screen helper class, that we use across all our new projects:

class Screen {
  static double get _ppi => (Platform.isAndroid || Platform.isIOS)? 150 : 96;
  static bool isLandscape(BuildContext c) => MediaQuery.of(c).orientation == Orientation.landscape;
  //PIXELS
  static Size size(BuildContext c) => MediaQuery.of(c).size;
  static double width(BuildContext c) => size(c).width;
  static double height(BuildContext c) => size(c).height;
  static double diagonal(BuildContext c) {
    Size s = size(c);
    return sqrt((s.width * s.width) + (s.height * s.height));
  }
  //INCHES
  static Size inches(BuildContext c) {
    Size pxSize = size(c);
    return Size(pxSize.width / _ppi, pxSize.height/ _ppi);
  }
  static double widthInches(BuildContext c) => inches(c).width;
  static double heightInches(BuildContext c) => inches(c).height;
  static double diagonalInches(BuildContext c) => diagonal(c) / _ppi;
}

To use

bool isLandscape = Screen.isLandscape(context)
bool isLargePhone = Screen.diagonal(context) > 720;
bool isTablet = Screen.diagonalInches(context) >= 7;
bool isNarrow = Screen.widthInches(context) < 3.5;

urllib is a standard python library (built-in) so you don't have to install it. just import it if you need to use request by:

import urllib.request

if it's not work maybe you compiled python in wrong way, so be kind and give us more details.

working for me after turn off ads block extension in chrome, this error sometime appear because something that block http in browser

I recommend setting the display options inside a context manager so that it only affects a single output. I usually prefer "pretty" html-output, and define a function force_show_all(df) for displaying the DataFrame df:

from IPython.core.display import display, HTML

def force_show_all(df):
    with pd.option_context('display.max_rows', None, 'display.max_columns', None, 'display.width', None):

below solution worked for me, follow steps to resolve your issue:

Step 1: Cancel Running

Step 2 : open Window menu and select Devices and Simulators

Step 3 : Unpair the iPhone

Step 4 : Removed iPhone USB cable and reconnect to the system

Step 5 : Pair the iPhone when you connect then you will be asked to Trust or Don't Allow, Please click Truct on your iPhone and enter your passcode (Pin Code)

Note : I performed all the above steps they worked for me. The issue of my device debugger gone.

Below is the Screenshot of Devices and Simulators Menu

For express, upgrade your express library to 4.17.1 which is the latest stable version. Then;

In CorsOption: Set origin to your localhost url or your frontend production url and credentials to true e.g

  const corsOptions = {
    origin: config.get("origin"),
    credentials: true,
  };

I set my origin dynamically using config npm module.

Then , in res.cookie:

For localhost: you do not need to set sameSite and secure option at all, you can set httpOnly to true for http cookie to prevent XSS attack and other useful options depending on your use case.

For production environment, you need to set sameSite to none for cross-origin request and secure to true. Remember sameSite works with express latest version only as at now and latest chrome version only set cookie over https, thus the need for secure option.

Here is how I made mine dynamic

 res
    .cookie("access_token", token, {
      httpOnly: true,
      sameSite: app.get("env") === "development" ? true : "none",
      secure: app.get("env") === "development" ? false : true,
    })

Please note that this article: https://medium.com/the-web-tub/supporting-iphone-x-for-mobile-web-cordova-app-using-onsen-ui-f17a4c272fcd has different sizes than above and cordova plugin page:

Default@2x~iphone~anyany.png (= 1334x1334 = 667x667@2x)
Default@2x~iphone~comany.png (= 750x1334 = 375x667@2x)
Default@2x~iphone~comcom.png (= 750x750 = 375x375@2x)
Default@3x~iphone~anyany.png (= 2436x2436 = 812x812@3x)
Default@3x~iphone~anycom.png (= 2436x1242 = 812x414@3x)

Default@2x~ipad~comany.png (= 1278x2732 = 639x1366@2x)

I resized images as above and updated ios platform and cordova-plugin-splashscreen to latest and the flash to white screen after a second issue was fixed. However the initial spash image has a white border at bottom now.

You can do like this to detect iPhone X device according to dimension.

Swift

if UIDevice().userInterfaceIdiom == .phone && UIScreen.main.nativeBounds.height == 2436 {
   //iPhone X
}

Objective - C

if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone && UIScreen.mainScreen.nativeBounds.size.height == 2436)  {
  //iPhone X     
}

But,

This is not sufficient way. What if Apple announced next iPhone with same dimension of iPhone X. so the best way is to use Hardware string to detect the device.

For newer device Hardware string is as below.

iPhone 8 - iPhone10,1 or iPhone 10,4

iPhone 8 Plus - iPhone10,2 or iPhone 10,5

iPhone X - iPhone10,3 or iPhone10,6

Most likely missing node_modules package in the angular project, run:

npm install

inside the angular project folder.

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

To fix this specific error, CSP should include this:

font-src 'self' data:;

So, index.html meta should read:

<meta http-equiv="Content-Security-Policy" content="font-src 'self' data:; img-src 'self' data:; default-src 'self' http://121.0.0:3000/">

This one I found simple solutions:

row = myArray.map((cell, i) => {

    if (i == myArray.length - 1) {
      return <div> Test Data 1</div>;
    }
    return <div> Test Data 2</div>;
  });

For CUDA:

Right Click on your project.

Go to Properties->CUDA and set "CUDA Toolkit Custom Dir" to your CUDA toolkit directory.

For me it was: C:\\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0

This is neither an exact answer to the question nor a silver bullet. However, if nothing works for you e.g. Invalidate cache & restart, Checking build dependency, Disabling Instant Run (I never advise that) etc.

1. Add command-line option --stacktrace in Setting > Build, Execution, Deployment > Compiler
2. Now build/assemble gradle once again. You will have detailed information about the cause. e.g. in my case:

Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.squareup.okhttp3:logging-interceptor:3.9.1Net.

I have misspelled the dependency name in module level gradle file. Hope that help

You have to change

loadNavItems() {
        this.navItems = this.http.get("../data/navItems.json");
        console.log(this.navItems);
    }

for

loadNavItems() {
        this.navItems = this.http.get("../data/navItems.json")
                        .map(res => res.json())
                        .do(data => console.log(data));
                        //This is optional, you can remove the last line 
                        // if you don't want to log loaded json in 
                        // console.
    }

Because this.http.get returns an Observable<Response> and you don't want the response, you want its content.

The console.log shows you an observable, which is correct because navItems contains an Observable<Response>.

In order to get data properly in your template, you should use async pipe.

<app-nav-item-comp *ngFor="let item of navItems | async" [item]="item"></app-nav-item-comp>

This should work well, for more informations, please refer to HTTP Client documentation

Try using the @ symbol before the url string. Import your css in the following manner:

import Vue from 'vue'

require('@/assets/styles/main.css')

In your App.vue file you can do this to import a css file in the style tag

<template>
  <div>
  </div>
</template>

<style scoped src="@/assets/styles/mystyles.css">
</style>

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

Just kill all node process and start npm server and run application:

Step1: run command killall -9 node

For windows users, run: taskkill /im node.exe

Run taskkill /f /im node.exe if the process still persists.

Step2: run command npm start --reset-cache

Step3: run command react-native run-ios OR react-native run-android

React Native buttons are very limited in the option they provide.You can use TouchableHighlight or TouchableOpacity by styling these element and wrapping your buttons with it like this

             <TouchableHighlight 
                style ={{
                    height: 40,
                    width:160,
                    borderRadius:10,
                    backgroundColor : "yellow",
                    marginLeft :50,
                    marginRight:50,
                    marginTop :20
                }}>
            <Button onPress={this._onPressButton}            
            title="SAVE"
            accessibilityLabel="Learn more about this button"
          /> 
          </TouchableHighlight> 

You can also use react library for customised button .One nice library is react-native-button (https://www.npmjs.com/package/react-native-button)

--
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
---

@NgModule({
  declarations: [   --   ],
  imports: [BrowserAnimationsModule],
  providers: [],
  bootstrap: []
})

Update:

Chain

You can now use the chain feature in packed mode as describe in Eugene's answer.

Guideline

You can use a horizontal guideline at 50% position and add bottom and top (8dp) constraints to edittext and button:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="16dp"
    android:paddingRight="16dp">

    <android.support.design.widget.TextInputLayout
        android:id="@+id/client_id_input_layout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        app:layout_constraintBottom_toTopOf="@+id/guideline"
        android:layout_marginRight="8dp"
        app:layout_constraintRight_toRightOf="parent"
        android:layout_marginLeft="8dp"
        app:layout_constraintLeft_toLeftOf="parent">

        <android.support.design.widget.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/login_client_id"
            android:inputType="textEmailAddress"/>

    </android.support.design.widget.TextInputLayout>

    <android.support.v7.widget.AppCompatButton
        android:id="@+id/authenticate"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:text="@string/login_auth"
        app:layout_constraintTop_toTopOf="@+id/guideline"
        android:layout_marginTop="8dp"
        android:layout_marginRight="8dp"
        app:layout_constraintRight_toRightOf="parent"
        android:layout_marginLeft="8dp"
        app:layout_constraintLeft_toLeftOf="parent"/>

    <android.support.constraint.Guideline
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/guideline"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.5"/>

</android.support.constraint.ConstraintLayout>

headerLeft: null

This won't work in the latest react native version

It should be:

navigationOptions = {
 headerLeft:()=>{},
}

For Typescript:

navigationOptions = {
 headerLeft:()=>{return null},
}

The command above worked for me

C:\Users\marcelo\Downloads\vs_community.exe --lang en-en --layout C:\VisualStudio2017 --all

1- Just open https://developer.android.com/studio/index.html

2- scroll down to the bottom of that page

3- download last version of tools for your OS (for example tools_r25.2.3-windows.zip)

4- Unzip it

5- Delete folder tools from previous Android Sdk folder

6- Copy new folder tools to Android SDK Folder like this image:

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_
_x000D_
}

<h1 class="keyword-title">Search results for<span class="securitySearchQuery"> "hi".</span></h1>

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

I think You are trying to use the normal URL of video Like this :

Copying Direct URL from YouTube

That doesn't let you display the content on other domains.To Tackle this up , You should use the Copy Embed Code feature provided by the YouTube itself .Like this :

Copy Embed Code ( YouTube )

That would free you up from any issues .

For the above Scenario :

• Go to Youtube Video

• Copy Embed Code

• Paste that into your Code ( Make sure you Escape all the " ( Inverted Commas) by \" .

If you read the message carefully you will see that you are using the permissions like camera, Microphone, Contacts, Storage and Phone, etc. and you don't supply a privacy policy. you need to supply a privacy policy if you do that. you can find more information about the android privacy policy on google

To Add Privacy Policy In-Play Console,

1. Find and select All Apps.

2. Select the application you need to add your Privacy Policy to.

3. Find the Policy at the end of the page.

4. Click App content to edit the listing for your app.

5. Find the field labeled Privacy Policy and place the URL of the page of your Privacy Policy

6. Click Save and you are good to go.

Note: You need to have a public web page to host your Privacy Policy. Google Play Store won't host the policy for you.

You likely have Hyper-V enabled. The manual installer provides this detailed notice when it refuses to install on a Windows with it on.

For HttpEntity, the below answer works

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

Here's an updated answer for the latest Bootstrap 4.0.0. This version has classes that will help you create a sticky or fixed sidebar without the extra CSS....

Use sticky-top:

<div class="container">
    <div class="row py-3">
        <div class="col-3 order-2" id="sticky-sidebar">
            <div class="sticky-top">
                ...
            </div>
        </div>
        <div class="col" id="main">
            <h1>Main Area</h1>
            ...   
        </div>
    </div>
</div>

Demo: https://codeply.com/go/O9GMYBer4l

or, use position-fixed:

<div class="container-fluid">
    <div class="row">
        <div class="col-3 px-1 bg-dark position-fixed" id="sticky-sidebar">
            ...
        </div>
        <div class="col offset-3" id="main">
            <h1>Main Area</h1>
            ...
        </div>
    </div>
</div>

Here is the correct implementation using numpy (np.log() is the natural logarithm)

import numpy as np
p = 100
r = 0.06 / 12
FV = 4000

n = np.log(1 + FV * r/ p) / np.log(1 + r)

print ("Number of periods = " + str(n))

Output:

Number of periods = 36.55539635919235

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

To compare date only with year - month - day and without time for me worked like this:

     let order = Calendar.current.compare(self.startDate, to: compareDate!, toGranularity: .day)  

                      switch order {
                        case .orderedAscending:
                            print("\(gpsDate) is after \(self.startDate)")
                        case .orderedDescending:
                            print("\(gpsDate) is before \(self.startDate)")
                        default:
                            print("\(gpsDate) is the same as \(self.startDate)")
                        }

Unlike jQuery in order to read raw JSON you will need to decode it in PHP.

print_r(json_decode(file_get_contents("php://input"), true));

php://input is a read-only stream that allows you to read raw data from the request body.

$_POST is form variables, you will need to switch to form radiobutton in postman then use:

foo=bar&foo2=bar2

To post raw json with jquery:

$.ajax({
    "url": "/rest/index.php",
    'data': JSON.stringify({foo:'bar'}),
    'type': 'POST',
    'contentType': 'application/json'
});

This error is often caused by incompatible jQuery versions. I encountered the same error with a foundation 6 repository. My repository was using jQuery 3, but foundation requires an earlier version. I then changed it and it worked.

If you look at the version of jQuery required by the foundation 5 dependencies it states "jquery": "~2.1.0".

Can you confirm that you are loading the correct version of jQuery?

I hope this helps.

The quickest way, just to get this working is to use the web pack from another location, this will stop you having to install it globally or if npm run webpack fails.

When you install webpack with npm it goes inside the "node_modules\.bin" folder of your project.

in command prompt (as administrator)

1. go to the location of the project where your webpack.config.js is located.
2. in command prompt write the following

"C:\Users\..\ProjectName\node_modules\.bin\webpack" --config webpack.config.vendor.js

2018 now. You don't need any extensions for auto-imports in Javascript (as long as you have checkjs: true in your jsconfig.json file) and TypeScript.

There are two types of auto imports: the add missing import quick fix which shows up as a lightbulb on errors:

And the auto import suggestions. These show up a suggestion items as you type. Accepting an auto import suggestion automatically adds the import at the top of the file

Both should work out of the box with JavaScript and TypeScript. If auto imports still do not work for you, please open an issue

Don't worry... Its much easy to solve your problem. Just SET you SDK-LOCATION and JDK-LOCATION.

• Click on Configure ( As Soon Android studio open )
• Click Project Default
• Click Project Structure

• Clik Android Sdk Location

• Select & Browse your Android SDK Location (Like: C:\Android\sdk)

• Uncheck USE EMBEDDED JDK LOCATION

• Set & Browse JDK Location, Like C:\Program Files\Java\jdk1.8.0_121

If anyone facing similar type of error while adding ShimmerRecyclerView Loader in android , make sure to add maven { url "https://jitpack.io" } under allprojects like below.

    allprojects {
    repositories {
        google()
        jcenter()
        //add it here
        maven { url "https://jitpack.io" }
      }
   }

You must have either disabled, froze or uninstalled FaceProvider in settings>applications>all
This will only happen if it's frozen, either uninstall it, or enable it.

It's the last selected DOM node index. Chrome assigns an index to each DOM node you select. So $0 will always point to the last node you selected, while $1 will point to the node you selected before that. Think of it like a stack of most recently selected nodes.

As an example, consider the following

<div id="sunday"></div>
<div id="monday"></div>
<div id="tuesday"></div>

Now you opened the devtools console and selected #sunday, #monday and #tuesday in the mentioned order, you will get ids like:

$0 -> <div id="tuesday"></div> 
$1 -> <div id="monday"></div>
$2 -> <div id="sunday"></div>

Note: It Might be useful to know that the node is selectable in your scripts (or console), for example one popular use for this is angular element selector, so you can simply pick your node, and run this:

angular.element($0).scope()

Voila you got access to node scope via console.

I recommend using React.createRef() and ref=this.elementRef to get the DOM element reference instead of ReactDOM.findDOMNode(this). This way you can get the reference to the DOM element as an instance variable.

import React, { Component } from 'react';
import ReactDOM from 'react-dom';

class MenuItem extends Component {

  constructor(props) {
    super(props);

    this.elementRef = React.createRef();
  }

  handleNVFocus = event => {
      console.log('Focused: ' + this.props.menuItem.caption.toUpperCase());
  }
    
  componentDidMount() {
    this.elementRef.addEventListener('nv-focus', this.handleNVFocus);
  }

  componentWillUnmount() {
    this.elementRef.removeEventListener('nv-focus', this.handleNVFocus);
  }

  render() {
    return (
      <element ref={this.elementRef} />
    )
  }

}

export default MenuItem;

If it says:

The term 'gradlew' is not recognized

Then using following command

npm start -- --reset-cache

worked for me. cheers!

The way you should be doing it in React Native (as I understand it), is by saving your 'global' variable in your index.js, for example. From there you can then pass it down using props.

Example:

    class MainComponent extends Component {

        componentDidMount() {
            //Define some variable in your component
            this.variable = "What's up, I'm a variable";
        }
        ...
        render () {
            <Navigator
                renderScene={(() => {
                    return(
                        <SceneComponent
                                //Pass the variable you want to be global through here
                                myPassedVariable={this.variable}/>
                    );
                })}/>
        }
    }


    class SceneComponent extends Component {

        render() {
            return(
                <Text>{this.props.myPassedVariable}</Text>
            );
        }

    }

Update for Bootstrap 5 (2020)

Bootstrap 5 (currently alpha) has a new xxl breakpoint. Therefore display classes have a new tier to support this:

Hidden only on xxl: d-xxl-none
Visible only on xxl: d-none d-xxl-block

Bootstrap 4 (2018)

The hidden-* and visible-* classes no longer exist in Bootstrap 4. If you want to hide an element on specific tiers or breakpoints in Bootstrap 4, use the d-* display classes accordingly.

Remember that extra-small/mobile (formerly xs) is the default (implied) breakpoint, unless overridden by a larger breakpoint. Therefore, the -xs infix no longer exists in Bootstrap 4.

Show/hide for breakpoint and down:

• hidden-xs-down (hidden-xs) = d-none d-sm-block
• hidden-sm-down (hidden-sm hidden-xs) = d-none d-md-block
• hidden-md-down (hidden-md hidden-sm hidden-xs) = d-none d-lg-block
• hidden-lg-down = d-none d-xl-block
• hidden-xl-down (n/a 3.x) = d-none (same as hidden)

Show/hide for breakpoint and up:

• hidden-xs-up = d-none (same as hidden)
• hidden-sm-up = d-sm-none
• hidden-md-up = d-md-none
• hidden-lg-up = d-lg-none
• hidden-xl-up (n/a 3.x) = d-xl-none

Show/hide only for a single breakpoint:

• hidden-xs (only) = d-none d-sm-block (same as hidden-xs-down)
• hidden-sm (only) = d-block d-sm-none d-md-block
• hidden-md (only) = d-block d-md-none d-lg-block
• hidden-lg (only) = d-block d-lg-none d-xl-block
• hidden-xl (n/a 3.x) = d-block d-xl-none
• visible-xs (only) = d-block d-sm-none
• visible-sm (only) = d-none d-sm-block d-md-none
• visible-md (only) = d-none d-md-block d-lg-none
• visible-lg (only) = d-none d-lg-block d-xl-none
• visible-xl (n/a 3.x) = d-none d-xl-block

Demo of the responsive display classes in Bootstrap 4

Also, note that d-*-block can be replaced with d-*-inline, d-*-flex, d-*-table-cell, d-*-table etc.. depending on the display type of the element. Read more on the display classes

Yarn is a recent package manager that probably deserves to be mentioned.
So, here it is: https://yarnpkg.com/

As far as I know it can fetch both npm and bower dependencies and has other appreciated features.

You will have to provide a link to your file that is accessible through the browser, that is for instance:

<a href="http://my.domain.com/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

versus

<a href="C:/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

If you expose your "Projecten" folder directly to the public, then you may only have to provide the link as such:

<a href="/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

But beware, that your files can then be indexed by search engines, can be accessed by anybody having this link, etc.

Have you checked your hidden input field where the token is generated?

If it is null then your token is not returned by csrf_token function.You have to write your route that renders the form inside the middleware group provide by laravel as follows:

  Route::group(['middleware' => 'web'], function () {
Route::get('/', function () {
    return view('welcome');
});

Here root route contains my sign up page which requires csrf token. This token is managed by laravel 5.2.7 inside 'web' middleware in kernel.php.

Do not forget to insert {!! csrf_field() !!} inside the form..

I was facing the same issue. After many tries below solution worked for me.

The content inside strings in Golang can be compared using == operator. If the results are not as expected there may be some hidden characters like \n, \r, spaces, etc. So as a general rule of thumb, try removing those using functions provided by strings package in golang.

For Instance, spaces can be removed using strings.TrimSpace function. You can also define a custom function to remove any character you need. strings.TrimFunc function can give you more power.

open build.gradle file. just add a space or press enter. then sync project. it works...

You've another instance of Tomcat already running. You can confirm this by going to http://localhost:8080 in your webbrowser and check if you get the Tomcat default home page or a Tomcat-specific 404 error page. Both are equally valid evidence that Tomcat runs fine; if it didn't, then you would have gotten a browser specific HTTP connection timeout error message.

You need to shutdown it. Go to /bin subfolder of the Tomcat installation folder and execute the shutdown.bat (Windows) or shutdown.sh (Unix) script.

You can also use Microsoft Visual Studio compiler instead of Cygwin or MinGW in Windows environment as the compiler for CLion.

Just go to find Actions in Help and type "Registry" without " and enable CLion.enable.msvc Now configure toolchain with Microsoft Visual Studio Compiler. (You need to download it if not already downloaded)

follow this link for more details: https://www.jetbrains.com/help/clion/quick-tutorial-on-configuring-clion-on-windows.html

In my case helped delete .npmrc config file

rm ~/.npmrc

I faced the same problem. There are two types of permissions in Android:

• Dangerous (access to contacts, write to external storage...)
• Normal

Normal permissions are automatically approved by Android while dangerous permissions need to be approved by Android users.

Here is the strategy to get dangerous permissions in Android 6.0

1. Check if you have the permission granted
2. If your app is already granted the permission, go ahead and perform normally.
3. If your app doesn't have the permission yet, ask for user to approve
4. Listen to user approval in onRequestPermissionsResult

Here is my case: I need to write to external storage.

First, I check if I have the permission:

...
private static final int REQUEST_WRITE_STORAGE = 112;
...
boolean hasPermission = (ContextCompat.checkSelfPermission(activity,
            Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
if (!hasPermission) {
    ActivityCompat.requestPermissions(parentActivity,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_WRITE_STORAGE);
}

Then check the user's approval:

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode)
    {
        case REQUEST_WRITE_STORAGE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                //reload my activity with permission granted or use the features what required the permission
            } else
            {
                Toast.makeText(parentActivity, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
    }

}

You can read more about the new permission model here: https://developer.android.com/training/permissions/requesting.html

Done Building Project "T:\workspace\machine.engine\Machine.engine.Test\Machine.engine.Test.csproj" (default targets) -- FAILED

Cause

After spending some time, I was using an internal developed component that was using Microsoft.Net.Compilers. The reason the internal component was using Microsoft.Net.Compilers was to overcome this issue (C#: throw invalid expression compilation) and was solved this way (How to use C# 7 with Visual Studio 2015?). This result in, when I installed the component on the main program, the Microsoft.Net.Compilers get added it selves automatically.

Solution

My work around was, uninstall following from our internal component by (following @malikKhalil answer)

PM> Uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform
PM> Uninstall-package Microsoft.Net.Compilers

And chose C# 7 compiler in Jenkins instead of C# 6 and rebuild, this is to ensure everything is working and building correctly.

Than finally in my main program I tried to update my internal component. And everything than build again. It has built without any problems or issues.

For me, this occurred after updating to XCode 11, like the others have said, it is a signing issue. What fixed it for me was to go to Developer portal > Certificates & Identifiers Edit the provisioning profile you are using

List of certificates Screenshot

You'll see that there's certificate for XCode 11 (as seen on screenshot) Just tick that box, re download the profile, and update your projects signing with the new profile.

If you mean to change default directory for "Node.js command prompt", when you launch it, then (Windows case)

1. go the directory where NodeJS was installed
2. find file nodevars.bat
3. open it with editor as administrator

4. change the default path in the row which looks like

   if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
   

with your path. It could be for example

    if "%CD%\"=="%~dp0" cd /d "c://MyDirectory/"

if you mean to change directory once when you launched "Node.js command prompt", then execute the following command in the Node.js command prompt:

     cd c:/MyDirectory/

Bit counter-intuitive, but you must first setup a SDK for Java projects. On the bottom right of the IntelliJ welcome screen, select 'Configure > Project Defaults > Project Structure'.

The Project tab on the left will show that you have no SDK selected:

Therefore, you must click the 'New...' button on the right hand side of the dropdown and point it to your JDK. After that, you can go back to the import screen and it should be populated with your JAVA_HOME variable, providing you have this set.

Sometimes, patience is key.

I had the same problem with a java project with big node_modules / .m2 directories.
The indexing was very long so I paused it and it prevented me from using Run Configurations.

So I waited for the indexing to finish and only then I was able to run my main class.

You do not need to keep the system images unless you want to use the emulator on your desktop. Along with it you can remove other unwanted stuff to clear disk space.

Adding as an answer to my own question as I've had to narrate this to people in my team more than a few times. Hence this answer as a reference to share with other curious ones.

In the last few weeks there were several colleagues who asked me how to safely get rid of the unwanted stuff to release disk space (most of them were beginners). I redirected them to this question but they came back to me for steps. So for android beginners here is a step by step guide to safely remove unwanted stuff.

Note

• Do not blindly delete everything directly from disk that you "think" is not required occupying. I did that once and had to re-download.
• Make sure you have a list of all active projects with the kind of emulators (if any) and API Levels and Build tools required for those to continue working/compiling properly.

First, be sure you are not going to use emulators and will always do you development on a physical device. In case you are going to need emulators, note down the API Levels and type of emulators you'll need. Do not remove those. For the rest follow the below steps:

Steps to safely clear up unwanted stuff from Android SDK folder on the disk

1. Open the Stand Alone Android SDK Manager. To open do one of the following:

• Click the SDK Manager button on toolbar in android studio or eclipse
• In Android Studio, go to settings and search "Android SDK". Click Android SDK -> "Open Standalone SDK Manager"
• In Eclipse, open the "Window" menu and select "Android SDK Manager"
• Navigate to the location of the android-sdk directory on your computer and run "SDK Manager.exe"

.

2. Uncheck all items ending with "System Image". Each API Level will have more than a few. In case you need some and have figured the list already leave them checked to avoid losing them and having to re-download.

.

3. Optional (may help save a marginally more amount of disk space): To free up some more space, you can also entirely uncheck unrequired API levels. Be careful again to avoid re-downloading something you are actually using in other projects.

.

4. In the end make sure you have at least the following (check image below) for the remaining API levels to be able to seamlessly work with your physical device.

In the end the clean android sdk installed components should look something like this in the SDK manager.

This error occurs when the version of Xcode predates that of the device.

For example, attempting to run a build on a device running iOS 9.3 in Xcode 7.2 results in this error; Could not find Developer Disk Image.

Why an error message that actually describes what the hell is going on can't be provided is beyond me (Apple, I'm looking at you ).

Update to the latest version of Xcode through the App Store or via direct download to guarantee interoperability with connected iOS hardware.

There's elegant solution:

Just mount not whole directory, but only app directory. This way you'll you won't have troubles with npm_modules.

Example:

  frontend:
    build:
      context: ./ui_frontend
      dockerfile: Dockerfile.dev
    ports:
    - 3000:3000
    volumes:
    - ./ui_frontend/src:/frontend/src

Dockerfile.dev:

FROM node:7.2.0

#Show colors in docker terminal
ENV COMPOSE_HTTP_TIMEOUT=50000
ENV TERM="xterm-256color"

COPY . /frontend
WORKDIR /frontend
RUN npm install update
RUN npm install --global typescript
RUN npm install --global webpack
RUN npm install --global webpack-dev-server
RUN npm install --global karma protractor
RUN npm install
CMD npm run server:dev

Here are some things that can fix this (in increasing order of difficulty):

• Clean the project (Product > Clean)

• Manually paste in

  @IBOutlet weak var viewName: UIView!
  // or
  @IBAction func viewTapped(_ sender: Any) { }
  

  and control drag to it. (Change type as needed.) Also see this.

• Completely close Xcode and restart your project.

• Delete the Derived Data folder (Go to Xcode > Preferences > Locations and click the gray arrow by the Derived Data folder. Then delete your project folder.)
• Click delete on the class, remove reference (not Move to Trash), and add it back again. (see this answer)

I just re-import maven button, then the error disappeared.

For Some reason it is not working so we can do this by another way

just remove the line and add this :-

<a onclick="window.open ('http://www.foracure.org.au', ''); return false" href="javascript:void(0);"></a>

Good luck.

Simply go to project Explorer and change your View from Android to project from drop Down and you are good to go.There you can simply create folder like we do in Eclipse. And in android project view it is hidden but when you switch to project. You can create folder like drawable-hdpi,drawable-xhdpi.

Temporarily show Menu Bar on ATOM:

Press ALT Key to make the Menu bar appear but it is not permanent.

Always display the Menu Bar on ATOM:

To make the change permanent, press ALT + V and then select Toggle Menu Bar option from the "View" drop-down down.

[Tested on ATOM running on Ubuntu 16.04]

I was able to get this work. I added the following to my custom CSS:

.wpcf7-form textarea{ 
    width: 100% !important;
    height:50px;
}

It's quite late, but I'm still posting it as it may help someone else.

Use the code below as a reference to check a single item in RecyclerView:

/**
 * Created by subrahmanyam on 28-01-2016, 04:02 PM.
 */
public class SampleAdapter extends RecyclerView.Adapter<SampleAdapter.ViewHolder> {

    private final String[] list;
    private int lastCheckedPosition = -1;

    public SampleAdapter(String[] list) {
        this.list = list;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = View.inflate(parent.getContext(), R.layout.sample_layout, null);
        ViewHolder holder = new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.choiceName.setText(list[position]);
        holder.radioButton.setChecked(position == lastCheckedPosition);
    }

    @Override
    public int getItemCount() {
        return list.length;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        @Bind(R.id.choice_name)
        TextView choiceName;
        @Bind(R.id.choice_select)
        RadioButton radioButton;

        public ViewHolder(View itemView) {
            super(itemView);
            ButterKnife.bind(this, itemView);
            radioButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int copyOfLastCheckedPosition = lastCheckedPosition;
            lastCheckedPosition = getAdapterPosition();
            notifyItemChanged(copyOfLastCheckedPosition);
            notifyItemChanged(lastCheckedPosition);

                }
            });
        }
    }
}

Edit: Solution for L5.2+

There's a better and more straightforward solution.

Use Storage::url($filename) to get the full path/URL of a given file. Note that you need to set S3 as your storage filesystem in config/filesystems.php: 'default' => 's3'

Of course, you can also do Storage::disk('s3')->url($filename) in the same way.

As you can see in config/filesystems.php there's also a parameter 'cloud' => 's3' defined, that refers to the Cloud filesystem. In case you want to mantain the storage folder in the local server but retrieve/store some files in the cloud use Storage::cloud(), which also has the same filesystem methods, i.e. Storage::cloud()->url($filename).

The Laravel documentation doesn't mention this method, but if you want to know more about it you can check its source code here.

I managed to install a Python3 kernel besides the Python2. Here is the way I did it:

• open a new notebook in Jupyter
• copy and run the two cells here: Enable-Python-3-kernel

The latest working link can be found here.

The actual code is:

! mkdir -p ~/.ipython/kernels/python3
%%file ~/.ipython/kernels/python3/kernel.json

{
 "display_name": "IPython (Python 3)", 
 "language": "python", 
 "argv": [
  "python3", 
  "-c", "from IPython.kernel.zmq.kernelapp import main; main()", 
  "-f", "{connection_file}"
 ], 
 "codemirror_mode": {
  "version": 2, 
  "name": "ipython"
 }
}

To disable Screen Capture:

Add following line of code in onCreate() method:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,
                           WindowManager.LayoutParams.FLAG_SECURE);

To enable Screen Capture:

Find for LayoutParams.FLAG_SECURE and remove the line of code.

Swift 5 : For evenly distributed spaces between cells with dynamic cell width to make the best of container space you may use the code snippet below by providing a minimumCellWidth value.

private func collectionViewLayout() -> UICollectionViewLayout {
    
    let layout = UICollectionViewFlowLayout()
    layout.sectionHeadersPinToVisibleBounds = true
    // Important: if direction is horizontal use minimumItemSpacing instead. 
    layout.scrollDirection = .vertical
    
    let itemHeight: CGFloat = 240
    let minCellWidth :CGFloat = 130.0
    let minItemSpacing: CGFloat = 10
    let containerWidth: CGFloat = self.view.bounds.width
    let maxCellCountPerRow: CGFloat =  floor((containerWidth - minItemSpacing) / (minCellWidth+minItemSpacing ))
    
    let itemWidth: CGFloat = floor( ((containerWidth - (2 * minItemSpacing) - (maxCellCountPerRow-1) * minItemSpacing) / maxCellCountPerRow  ) )
    // Calculate the remaining space after substracting calculating cellWidth (Divide by 2 because of left and right insets)
    let inset = max(minItemSpacing, floor( (containerWidth - (maxCellCountPerRow*itemWidth) - (maxCellCountPerRow-1)*minItemSpacing) / 2 ) )

    
    layout.itemSize = CGSize(width: itemWidth, height: itemHeight)
    layout.minimumInteritemSpacing = min(minItemSpacing,inset)
    layout.minimumLineSpacing = minItemSpacing
    layout.sectionInset = UIEdgeInsets(top: minItemSpacing, left: inset, bottom: minItemSpacing, right: inset)

    
    return layout
}

Open the terminal and type :

export ANDROID_HOME=/Applications/ADT/sdk

Add this to the PATH environment variable

export PATH=$PATH:$ANDROID_HOME/platform-tools

If the terminal doesn't locate the added path(s) from the .bash_profile, please run this command

source ~/.bash_profile

Hope it works to you!

from Tkinter import *

app = Tk()

# Text Widget + Font Size
txt = Text(app, font=('Verdana',8))
txt.pack()

# Delete Button
btn = Button(app, text='Delete', command=lambda: txt.delete(1.0,END))
btn.pack()

app.mainloop()

Here's an example of txt.delete(1.0,END) as mentioned.

The use of lambda makes us able to delete the contents without defining an actual function.

it is different for different icons.(eg, diff sizes for action bar icons, laucnher icons, etc.) please follow this link icons handbook to learn more.

Sorry to tell you screencap just a simple command, only accept few arguments, but none of them can save time for you, here is the -h help output.

$ adb shell screencap -h
usage: screencap [-hp] [-d display-id] [FILENAME]
-h: this message
-p: save the file as a png.
-d: specify the display id to capture, default 0.
If FILENAME ends with .png it will be saved as a png.
If FILENAME is not given, the results will be printed to stdout.

Besides the command screencap, there is another command screenshot, I don't know why screenshot was removed from Android 5.0, but it's avaiable below Android 4.4, you can check the source from here. I didn't make my comparison which is faster between these two commands, but you can give your try in your real environment and make the final decision.

A solution for me was to create a UILabel and add it to the UIButton as a subview. Finally I added a constraint to center it within the button.

UILabel * myTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 75, 75)];
myTextLabel.text = @"Some Text";
myTextLabel.translatesAutoresizingMaskIntoConstraints = false;

[myButton addSubView:myTextLabel];

// Add Constraints
[[myTextLabel centerYAnchor] constraintEqualToAnchor:myButton.centerYAnchor].active = true;
[[myTextLabel centerXAnchor] constraintEqualToAnchor:myButton.centerXAnchor].active = true; 

FFMpeg can do this by seeking to the given timestamp and extracting exactly one frame as an image, see for instance:

ffmpeg -i input_file.mp4 -ss 01:23:45 -vframes 1 output.jpg

Let's explain the options:

-i input file           the path to the input file
-ss 01:23:45            seek the position to the specified timestamp
-vframes 1              only handle one video frame
output.jpg              output filename, should have a well-known extension

The -ss parameter accepts a value in the form HH:MM:SS[.xxx] or as a number in seconds. If you need a percentage, you need to compute the video duration beforehand.

The problem is that .form-control class renders like a DIV element which according to the normal-flow-of-the-page renders on a new line.

One way of fixing issues like this is to use display:inline property. So, create a custom CSS class with display:inline and attach it to your component with a .form-control class. You have to have a width for your component as well.

There are other ways of handling this issue (like arranging your form-control components inside any of the .col classes), but the easiest way is to just make your .form-control an inline element (the way a span would render)

The left inset is caused by Toolbar's contentInsetStart which by default is 16dp.

Change this to align to the keyline.

Update for support library v24.0.0:

To match the Material Design spec there's an additional attribute contentInsetStartWithNavigation which by default is 16dp. Change this if you also have a navigation icon.

It turned out that this is part of a new Material Design Specification introduced in version 24 of Design library.

https://material.google.com/patterns/navigation.html

However, it is possible to remove the extra space by adding the following property to Toolbar widget.

app:contentInsetStartWithNavigation="0dp"

Before :

After :

you may change your loop condition according to following code, when length of l is smaller than buffer size it means that it reached end of file

while (True):
    print "Receiving..."
    l = c.recv(1024)        
    f.write(l)
    if len(l) < 1024:
        break

I got this error briefly after renaming the App_Code folder. Actually, I accidentally dragged the whole folder to the App_data folder. VS 2015 didn't complain it was difficult to spot what had gone wrong.

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

Edit: See Jayprakash Dubey's answer for iTunes 12.7

From the menu shown in the following screenshot, choose Apps. You can drag and drop you IPA file in the next view.

After that, go to your device's page, you'll see the list of apps, install your app and press Apply from the bottom bar.

I know that there is already a solution to this question, but I found an alternative to this issue and maybe it could help someone.

I was having trouble with setting the frame of my sub view because certain values were referring to its position within the main view. So if you don't want to update your frame by changing the whole frame via CGRect, you can simply change a value of the frame and then update it.

// keep reference to you frames
var questionView = questionFrame.frame
var answerView = answerFrame.frame

// update the values of the copy        
questionView.size.height = CGFloat(screenSize.height * 0.70)
answerView.size.height = CGFloat(screenSize.height * 0.30)

// set the frames to the new frames
questionFrame.frame = questionView
answerFrame.frame = answerView

Per the developers, this error is not an actual failure, but rather "misleading error reports". This bug is fixed in version 40, which is available on the canary and dev channels as of 25 Oct.

Patch

This post helped me A LOT!

I added UIViewAlertForUnsatisfiableConstraints symbolic breakpoint with suggested action:

Obj-C project

po [[UIWindow keyWindow] _autolayoutTrace]

Swift project

expr -l objc++ -O -- [[UIWindow keyWindow] _autolayoutTrace]

With this hint, the log became more detailed, and It was easier for me identify which view had the constraint broken.

Then I paused execution and I changed problematic view's background color with the command (replacing 0x7f88a8cc2050 with the memory address of your object of course)...

Obj-C

expr ((UIView *)0x7f88a8cc2050).backgroundColor = [UIColor redColor]

Swift 3.0

expr -l Swift -- import UIKit
expr -l Swift -- unsafeBitCast(0x7f88a8cc2050, to: UIView.self).backgroundColor = UIColor.red

... and the result It was awesome!

Simply amazing! Hope It helps.

I also faced this same issue, I got a solution with this.

I did the following steps :

1. Open system properties
2. Environment variables
3. create a new system variable
4. name: ANDROID_HOME
5. value: copy your SDK path( Ex: my SDK path E:\SoftWares\Android-SDK)

close your current cmd, and restart it run flutter doctor

this should work on windows

When the length of v will be zero, it'll give you the value error.

You should check the length or you should check the list first whether it is none or not.

if list:
    k.index(max(list))

or

len(list)== 0

The answer I have finally found is that the SMTP service on the server is not using the same certificate as https.

The diagnostic steps I had read here make the assumption they use the same certificate and every time I've tried this in the past they have done and the diagnostic steps are exactly what I've done to solve the problem several times.

In this case those steps didn't work because the certificates in use were different, and the possibility of this is something I had never come across.

The solution is either to export the actual certificate from the server and then install it as a trusted certificate on my machine, or to get a different valid/trusted certificate for the SMTP service on the server. That is currently with our IT department who administer the servers to decide which they want to do.

I have the same issue. I click ok in xcode and when launching the app on my iPhone I'm asked if I want to trust this application. Doing it, the app runs and further build-and-run from xcode went without any issue until deleting the app from the iPhone and reinstalling it. Then goto first line ;-)

Predicted

According to the Apple website the iPhone 6 Plus will have 401 pixels-per-inch and be 1920 x 1080. The smaller version of the iPhone 6 will be 1334 x 750 with 326 PPI.

So, assuming that information is correct, we can write a media query for the iPhone 6:

@media screen 
    and (min-device-width : 1080px) 
    and (max-device-width : 1920px) 
    and (min-resolution: 401dpi) 
    and (device-aspect-ratio:16/9) 
{ }

@media screen 
    and (min-device-width : 750px) 
    and (max-device-width : 1334px) 
    and (min-resolution: 326dpi) 
{ }

Note that device-aspect-ratio will be deprecated in http://dev.w3.org/csswg/mediaqueries-4/ and replaced with aspect-ratio

Min-width and max-width may be something like 1704 x 960.

Apple Watch (speculative)

Specs on the Watch are still a bit speculative since (as far as I'm aware) there has been no official spec sheet yet. But Apple did mention in this press release that the Watch will be available in two sizes.. 38mm and 42mm.

Further assuming.. that those sizes refer to the screen size rather than the overall size of the Watch face these media queries should work.. And I'm sure you could give or take a few millimeters to cover either scenario without sacrificing any unwanted targeting because..

@media (!small) and (damn-small), (omfg) { }

or

@media 
    (max-device-width:42mm) 
    and (min-device-width:38mm) 
{ }

It's worth noting that Media Queries Level 4 from W3C currently only available as a first public draft, once available for use will bring with it a lot of new features designed with smaller wearable devices like this in mind.

Also - please note that you may have transparency set even if you don't actually have any transparency in your images. If you're using photoshop, 'save for web' and de-select 'transparency' or just convert your image to a .jpg. iTunes Connect seems to reject transparencies as well.

Here a single example using Duration and TimeUnit to get 'hh:mm:ss' format.

Duration dur = Duration.between(localDateTimeIni, localDateTimeEnd);
long millis = dur.toMillis();

String.format("%02d:%02d:%02d", 
        TimeUnit.MILLISECONDS.toHours(millis),
        TimeUnit.MILLISECONDS.toMinutes(millis) - 
        TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
        TimeUnit.MILLISECONDS.toSeconds(millis) - 
        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

In iOS 9.1 and lower, go to Settings - General - Profiles - tap on your Profile - tap on Trust button.

You question is a bit unclear as to what you want, but judging from your comments, I assume you want each bubble to cover the screen, both vertically and horizontally. In that case, the vertical part is the tricky part.

As many others have answered, you first need to make sure that you are setting the viewport meta tag to trigger mobile devices to use their "ideal" viewport instead of the emulated "desktop width" viewport. The easiest and most fool proof version of this tag is as follows:

<meta name="viewport" content="width=device-width, initial-scale=1">

Source: PPK, probably the leading expert on how this stuff works. (See http://quirksmode.org/presentations/Spring2014/viewports_jqueryeu.pdf).

Essentially, the above makes sure that media queries and CSS measurements correspond to the ideal display of a virtual "point" on any given device — instead of shrinking pages to work with non-optimized desktop layouts. You don't need to understand the details of it, but it's important.

Now that we have a correct (non-faked) mobile viewport to work with, adjusting to the height of the viewport is still a tricky subject. Generally, web pages are fine to expand vertically, but not horizontally. So when you set height: 100% on something, that measurement has to relate to something else. At the topmost level, this is the size of the HTML element. But when the HTML element is taller than the screen (and expands to contain the contents), your measurements in percentages will be screwed up.

Enter the vh unit: it works like percentages, but works in relation to the viewport, not the containing block. MDN info page here: https://developer.mozilla.org/en-US/docs/Web/CSS/length#Viewport-percentage_lengths

Using that unit works just like you'd expect:

.bubble { height: 100vh; } /* be as tall as the viewport height. Done. */

It works on a lot of browsers (IE9 and up, modern Firefox, Safari, Chrome, Opera etc) but not all (support info here: http://caniuse.com/#search=vh). The downside in the browsers where it does work is that there is a massive bug in iOS6-7 that makes this technique unusable for this very case (details here: https://github.com/scottjehl/Device-Bugs/issues/36). It will be fixed in iOS8 though.

Depending on the HTML structure of your project, you may get away with using height: 100% on each element that is supposed to be as tall as the screen, as long as the following conditions are met:

1. The element is a direct child element of <body>.
2. Both the html and body elements have a 100% height set.

I have used that technique in the past, but it was long ago and I'm not sure it works on most mobile devices. Try it and see.

The next choice is to use a JavaScript helper to resize your elements to fit the viewport. Either a polyfill fixing the vh issues or something else altogether. Sadly, not every layout is doable in CSS.

Most probably, you didn't install any SQL Server Engine service. If no SQL Server engine is installed, no service will appear in the SQL Server Configuration Manager tool. Consider that the packages SQLManagementStudio_Architecture_Language.exe and SQLEXPR_Architecture_Language.exe, available in the Microsoft site contain, respectively only the Management Studio GUI Tools and the SQL Server engine.

If you want to have a full featured SQL Server installation, with the database engine and Management Studio, download the installer file of SQL Server with Advanced Services. Moreover, to have a sample database in order to perform some local tests, use the Adventure Works database.

Considering the package of SQL Server with Advanced Services, at the beginning at the installation you should see something like this (the screenshot below is about SQL Server 2008 Express, but the feature selection is very similar). The checkbox next to "Database Engine Services" must be checked. In the next steps, you will be able to configure the instance settings and other options.

Execute again the installation process and select the database engine services in the feature selection step. At the end of the installation, you should be able to see the SQL Server services in the SQL Server Configuration Manager.

I was having trouble coloring rows in table using bootstrap table-striped class then realized delete table-striped class and do this in css file

tr:nth-of-type(odd)
{  
background-color: red;
}
tr:nth-of-type(even)
{  
background-color: blue;
}

The bootstrap table-striped class will over ride your selectors.

From Batch file, ping a ip only once using the following command:

Try first in Android Studio:

File -> Sync Project with Gradle Files

I tried the answer described here but it doesn´t worked for me. I have the last Android SDK tools ver. 23.0.2 and Android SDK Platform-tools ver. 20

The support library android-support-v4.jar is causing this conflict, just delete the library under /libs folder of your project, don´t be scared, the library is already contained in the library appcompat_v7, clean and build your project, and your project will work like a charm!

That's because you may using the repository cloned from the git or svn. Try to clone another new version and run it.

I did as how moplin mentioned .But in my case service send the JWT in response headers ,as a value under the key "Authorization".

Authorization ?Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJpbWFsIiwiZXhwIjoxNDk4OTIwOTEyfQ.dYEbf4x5TGr_kTtwywKPI2S-xYhsp5RIIBdOa_wl9soqaFkUUKfy73kaMAv_c-6cxTAqBwtskOfr-Gm3QI0gpQ

What I did was ,make a Global variable in postman as

key->jwt
value->blahblah

in login request->Tests Tab, add

postman.clearGlobalVariable("jwt");
postman.setGlobalVariable("jwt", postman.getResponseHeader("Authorization"));

in other requests select the Headers tab and give

key->Authorization

value->{{jwt}}

I got his error when i was trying to access UILabel. I forgot to connect the UILabel to IBOutlet in Storyboard and that was causing the app to crash with this error!!

Yes I got the trick.

public void onClick(View v) {

            if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH ){
                imgDisplay.setSystemUiVisibility( View.SYSTEM_UI_FLAG_HIDE_NAVIGATION );

            }
            else if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB )
                imgDisplay.setSystemUiVisibility( View.STATUS_BAR_HIDDEN );
            else{}

    }

But it didn't solve my problem completely. I want to hide the horizontal scrollview too, which is in front of the imageView (below), which can't be hidden in this.

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories, and it should work.

The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

Turn the Pluralization On. The problem is that you model object are using singular name (Pupil) convention, while in your database you are using pluralized names Pupils with s.

UPDATE

This post shows how can you turn it on or off. Some relevant excerpt of that post:

To turn pluralization on and off

• On the Tools menu, click Options.

• In the Options dialog box, expand Database Tools. Note: Select Show all settings if the Database Tools node is not visible.

• Click O/R Designer.

• Set Pluralization of names to Enabled = False to set the O/R Designer so that it does not change class names.

• Set Pluralization of names to Enabled = True to apply pluralization rules to the class names of objects added to the O/R Designer.

UPDATE 2

But note that, you should avoid pluralized names. You can read here how to do it (I'll cite it here, just in case the link gets broken).

(...) When you work with Entity Framework Code First approach, you are creating your database tables from your model classes. Usually Entity Framework will create tables with Pluralized names. that means if you have a model class called PhoneNumber, Entity framework will create a table for this class called “PhoneNumbers“. If you wish to avoid pluralized name and wants singular name like Customer , you can do it like this In your DBContext class, Override the “OnModelCreating” method like this (...)

(...) Having this Method Overriding will avoid creating tables with pluralized names. Now it will create a Table called “PhoneNumber” , Not “PhoneNumbers” (...)

After initial few days of struggle, I finally managed to successfully integrate Facebook signup to my iOS app. Here are the steps(I am assuming you have already installed Facebook SDK v4.1 or above in your machines):

1. Add the Facebook frameworks - FBSDKCoreKit,FBSDKLoginKit under your project.
2. Make no changes in the Build settings as FB SDK v4.1 and above doesn't need anymore bridging header files.
3. Import the FBSDKCorekit, FBSDKLoginKit in ViewController.swift, AppDelegate.swift files

4. Add informations in the pList as mentioned here

5. Build your app. And wohoo! no compile time errors.

The fact that GitHub changed master to main made me encounter this issue. So from now on, the solution to push to origin is:

git push -u origin main

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

I had the same problem, and a easy way i found to solve that was to make everything in the modal's body responsive(using boostrap classes) and my problem were solved.

In case this may be helpful for someone who just needs to show colors rather than output, as a hackish workaround (and FYI), since GitHub supports Unicode (as Unicode, numeric character references or HTML entities), you could try colored Unicode symbols, though it depends on the font rendering them in color (as it happens to be appearing for me on Windows 10 and Mac 10.12.5, at least, though on the Mac at least, the up/down-pointing small red triangles don't show in red):

After so many trials I stumbled on a solution to this. I generated and added both debug and release keys to the Facebook developer console and still got the error.

The only solution that worked for me was is to uninstall the OpenSSL program from Google and download from Win32/Win64 OpenSSL Installer for Windows

It really works like magic.

As of Chrome 52, the UI has changed. When the Developer Tools dialog is open, you select the vertical ellipsis and can then choose the docking position:

Select the icon on the left to open the Chrome Developer Tools in a new window:

Previously

Click and hold the button next to the close button of the Developer Tool in order to reveal the "Undock into separate window" option.

Note: A "press" is not enough in that state.

            protected void onPostExecute(Void result) {
                Log.d(TAG, "long thread onPostExecute");
                if (mProgressDialog != null && mProgressDialog.isShowing()) {
                    mProgressDialog.dismiss();
                    mProgressDialog = null;
                }
                Log.d(TAG, "long thread onPostExecute call dismiss");
            }
        }.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);

        new AsyncTask<Void, Void, Void>(){
            @Override
            protected Void doInBackground(Void... params) {
                try {
                    Log.d(TAG, "short thread doInBackground");
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                return null;
            }

            @Override
            protected void onPostExecute(Void aVoid) {
                super.onPostExecute(aVoid);
                Log.d(TAG, "short thread onPostExecute");
                finish();
                Log.d(TAG, "short thread onPostExecute call finish");
            }
        }.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        Log.d(TAG, "onDestroy");
    }
}

You can try this and find out what is the best way to fix this issue. From my study, there are at least 4 ways to fix it:

1. @erakitin's answer: call isFinishing() to check activity's state
2. @Kapé's answer: set flag to check activity's state
3. Use try/catch to handle it.
4. Call AsyncTask.cancel(false) in onDestroy(). It will prevent the asynctask to execute onPostExecute() but execute onCancelled() instead.
   Note: onPostExecute() will still execute even you call AsyncTask.cancel(false) on older Android OS, like Android 2.X.X.

You can choose the best one for you.

do you called the ViewTreeObserver and not remove it.

    mEtEnterlive.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
         // do nothing here can cause such problem
    });

Changing language-specific configuration

I changed the default tab settings, and it still did not impact when I was editing my files, which were Python files. It also did not change when I modified the "*" setting in ~/.atom/config.cson . I don't have a good explanation for either of those.

However, when I added the following to my config.cson, I was able to change the tab in my Python files to 2 spaces:

'.source.python':
  editor:
    tabLength: 2

Thanks to this resource for the solution: Tab key not respecting tab length

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

If you have pushed the commits upstream...

Select the commit you would like to roll back to and reverse the changes by clicking Reverse File, Reverse Hunk or Reverse Selected Lines. Do this for all the commits after the commit you would like to roll back to also.

If you have not pushed the commits upstream...

Right click on the commit and click on Reset current branch to this commit.

You can also do this:

//Get the current claims principal
var identity = (ClaimsPrincipal)Thread.CurrentPrincipal;
var claims = identity.Claims;

Update

To provide further explanation as per comments.

If you are creating users within your system as follows:

UserManager<applicationuser> userManager = new UserManager<applicationuser>(new UserStore<applicationuser>(new SecurityContext()));
ClaimsIdentity identity = userManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);

You should automatically have some Claims populated relating to you Identity.

To add customized claims after a user authenticates you can do this as follows:

var user = userManager.Find(userName, password);
identity.AddClaim(new Claim(ClaimTypes.Email, user.Email));

The claims can be read back out as Darin has answered above or as I have.

The claims are persisted when you call below passing the identity in:

AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = persistCookie }, identity);

Make Sure in left panel App review tab selected (Your app is currently live and available to the public.) tab is ON and App status is GREEN

Happy Programming

Into the Preferences > Setting - Default

You will have the next by default:

// Display file encoding in the status bar
    "show_encoding": false

You could change it or like cdesmetz said set your user settings.

A (partial) practical work-around is to put things into a throw-away function.

Pasting

x = 1
x += 1
print(x)

results in

>>> x = 1
x += 1
print(x)
  File "<stdin>", line 1
    x += 1
print(x)

    ^
SyntaxError: multiple statements found while compiling a single statement
>>>

However, pasting

def abc():
  x = 1
  x += 1
  print(x)

works:

>>> def abc():
  x = 1
  x += 1
  print(x)
>>> abc()
2
>>>

Of course, this is OK for a quick one-off, won't work for everything you might want to do, etc. But then, going to ipython / jupyter qtconsole is probably the next simplest option.

1. Go to Control panel.
2. Double click on Java.
3. Go to Security tab.
4. Change security from high to medium.

Your applets will run.

If they are still not running then you have to add that website name in exception site list of Security tab of Java in Control panel.

This is not issue but this is by design. The root cause is described in Microsoft Support Page.

The Response.End method ends the page execution and shifts the execution to the Application_EndRequest event in the application's event pipeline. The line of code that follows Response.End is not executed.

Pure CSS method

It is possible to center a video inside an element just like a cover sized background-image without JS using the object-fit attribute or CSS Transforms.

2021 answer: object-fit

As pointed in the comments, it is possible to achieve the same result without CSS transform, but using object-fit, which I think it's an even better option for the same result:

.video-container {
    height: 300px;
    width: 300px;
    position: relative;
}

.video-container video {
  width: 100%;
  height: 100%;
  position: absolute;
  object-fit: cover;
  z-index: 0;
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
    <video autoplay muted loop>
        <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
    </video>
    <div class="caption">
      <h2>Your caption here</h2>
    </div>
</div>

Previous answer: CSS Transform

You can set a video as a background to any HTML element easily thanks to transform CSS property.

Note that you can use the transform technique to center vertically and horizontally any HTML element.

.video-container {
  height: 300px;
  width: 300px;
  overflow: hidden;
  position: relative;
}

.video-container video {
  min-width: 100%;
  min-height: 100%;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translateX(-50%) translateY(-50%);
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
  <video autoplay muted loop>
    <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
  </video>
  <div class="caption">
    <h2>Your caption here</h2>
  </div>
</div>

To solve this problem just call jQuery file before the bootstrap file

in the header section you have to write

Authorization: Basic aG9sY67890vbGNpbQ==

where string after basic is the 64bit encoding value of your username:password. php example of getting the header values is: echo "Authorization: Basic " . base64_encode("myUser:myPassword");

n.b: I assumed your authentication method as basic. which can be different as well.

Your .mobile div has the following styles on it:

.mobile {
    display: none !important;
    visibility: hidden !important;
}

Therefore you need to override the visibility property with visible in addition to overriding the display property with block. Like so:

.visible-sm {
    display: block !important;
    visibility: visible !important;
}

Why I prefer Fragment over Activity in ALL CASES.

• Activity is expensive. In Fragment, views and property states are separated - whenever a fragment is in backstack, its views will be destroyed. So you can stack much more Fragments than Activity.

• Backstack manipulation. With FragmentManager, it's easy to clear all the Fragments, insert more than on Fragments and etcs. But for Activity, it will be a nightmare to manipulate those stuff.

• A much predictable lifecycle. As long as the host Activity is not recycled. the Fragments in the backstack will not be recycled. So it's possible to use FragmentManager::getFragments() to find specific Fragment (not encouraged).

Do not bind to element id, just use the 'previous' input element to clear.

CSS:

.clear-input > span {
    position: absolute;
    right: 24px;
    top: 10px;
    height: 14px;
    margin: auto;
    font-size: 14px;
    cursor: pointer;
    color: #AAA;
}

Javascript:

function $(document).ready(function() {
    $(".clear-input>span").click(function(){
        // Clear the input field before this clear button
        // and give it focus.

        $(this).prev().val('').focus();
    });
});

HTML Markup, use as much as you like:

<div class="clear-input">
    Pizza: <input type="text" class="form-control">
    <span class="glyphicon glyphicon-remove-circle"></span>
</div>

<div class="clear-input">
    Pasta: <input type="text" class="form-control">
    <span class="glyphicon glyphicon-remove-circle"></span>
</div>

Right Click on Project > Properties > Java Build Path > Add the Test folder as source folder.

All source folders including Test Classes need to be in Eclipse Java Build Path. So that the sources such as main and test classes can be compiled into the build directory (Eclipse default folder is bin).

1. Right click on your Project in the project explorer
2. Click on properties
3. Click on Run
4. Make sure your Main Class is the one you want to be the entry point. (Make sure to use the fully qualified name i.e. mypackage.MyClass)
5. Click OK.
6. Clean an build your project
7. Run Project :)

If you just want to run the file, right click on the class from the package explorer, and click Run File, or (Alt + R, F), or (Shift + F6)

Will something like this work for you? What this does is query the content resolver to find the file path data that is stored for that content entry

public static String getRealPathFromUri(Context context, Uri contentUri) {
    Cursor cursor = null;
    try {
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

This will end up giving you an absolute file path that you can construct a file uri from

I was interested in setting up graphics for Code Blocks when I ran into a this error: (took me 2 hrs to solve it)

I guess you need to have a bit of luck with this. In my case i just changed the order of contents in Settings menu->Compiler and Debugger->Global compiler settings->Linker settings->Other Linker Options: The working sequence is: -lmingw32 -lSDL -lSDLmain

Bootstrap 3

Using Bootstrap 3's grid system:

<div class="container">
  <div class="row">
    <div class="col-xs-4">Menu</div>
    <div class="col-xs-8">
      <div class="row">
        <div class="col-md-4 col-md-push-8">Right Content</div>
        <div class="col-md-8 col-md-pull-4">Content</div>
      </div>
    </div>
  </div>
</div>

Working example: http://bootply.com/93614

Explanation

First, we set two columns that will stay in place no matter the screen resolution (col-xs-*).

Next, we divide the larger, right hand column in to two columns that will collapse on top of each other on tablet sized devices and lower (col-md-*).

Finally, we shift the display order using the matching class (col-md-[push|pull]-*). You push the first column over by the amount of the second, and pull the second by the amount of the first.

I found this question as I had a similar problem. While data-backdrop does "solve" the issue; I found another problem in my markup.

I had the button which launched this modal and the modal dialog itself was in the footer. The problem is that the footer was defined as navbar_fixed_bottom, and that contained position:fixed.

After I moved the dialog outside of the fixed section, everything worked as expected.

Just use the Form Paint method and draw every Picturebox on it, it allows transparency :

    private void frmGame_Paint(object sender, PaintEventArgs e)
    {
        DoubleBuffered = true;
        for (int i = 0; i < Controls.Count; i++)
            if (Controls[i].GetType() == typeof(PictureBox))
            {
                var p = Controls[i] as PictureBox;
                p.Visible = false;
                e.Graphics.DrawImage(p.Image, p.Left, p.Top, p.Width, p.Height);
            }
    }

Add android:exported="true" in your 'com.example.lib.MainActivity' activity tag.

From the android:exported documentation,

android:exported Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.

From your logcat output, clearly a mismatch in uid is causing the issue. So adding the android:exported="true" should do the trick.

for who still having issues with 1.9.4 change

//oSettings.aoColumns[i].nTh.style.width = _fnStringToCss(oSettings.aoColumns[i].sWidth);
oSettings.aoColumns[i].nTh.style.minWidth = _fnStringToCss(oSettings.aoColumns[i].sWidth);

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

You can wrap the columns inside a div

<div class="row">
<div class="col-md-12>
  <div class="col-xs-12 col-sm-4 panel" style="background-color: red">
  some content
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: yellow">
  kittenz
  <img src="http://placekitten.com/100/100">
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: blue">
  some more content
  </div>
</div>
</div>

Select the option by CSS property

element(by.model("organization.parent_id")).element(by.css("[value='1']")).click();

or

element(by.css("#locregion")).element(by.css("[value='1']")).click();

Where locregion(id), organization.parent_id(model name) are the attributes of select element.

If you want to add multiple files in a given folder you can split them using {,}. This is awesome for not repeating long paths, e.g.

git add long/path/{file1,file2,...,filen}

Beware not to put spaces between the ,.

I had got the same error. Because of security reasons, I could not see option for allowing Apps downloaded from Anywhere in System preference-> Security Tab.

I removed the extended attribute from Zip file by below command.

xattr -d com.apple.quarantine [Zip file path] 

And then got below error:- org.eclipse.e4.core.di.InjectionException: java.lang.NoClassDefFoundError: javax/annotation/PostConstruct

Resolved it by uninstalling all different versions of java and installed just 1.8.0_231.

Worked finally.

For selectively hiding Actionbar in activities:

Add the following code to onCreate (preferably on the last line of the function)

Kotlin:

supportActionBar?.hide()

Java:

getSupportActionBar().hide();

With the help of what @EML has described above regarding popover on modal windows and also the code shown by @2called-chaos, this is how I solved the problem.

I have a icon on the modal which when clicked should the popup

My HTML

<i title="" class="glyphicon glyphicon-info-sign" rel="popover" data-title="Several Lines" data-content="A - First line<br />B - Second line - Long line <br />C - Third Line - Long Long Long Line"></i>

My Script

    $('[rel=popover]').popover({
        placement: 'bottom',
        html: 'true',
        container: '#name-of-modal-window .modal-body'
    }).on("show.bs.popover", function () { $(this).data("bs.popover").tip().css("max-width", "600px"); });

I had a couple of issues with the answers here, such as when you added in the padding, the width of the content was overflowing the box and that I wanted some corner radius. I solved this using the following subclass of UILabel:

#import "MyLabel.h"

#define PADDING 8.0
#define CORNER_RADIUS 4.0

@implementation MyLabel

- (void)drawRect:(CGRect)rect {
 self.layer.masksToBounds = YES;
 self.layer.cornerRadius = CORNER_RADIUS;
 UIEdgeInsets insets = {0, PADDING, 0, PADDING};
 return [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}
- (CGSize) intrinsicContentSize {
 CGSize intrinsicSuperViewContentSize = [super intrinsicContentSize] ;
 intrinsicSuperViewContentSize.width += PADDING * 2 ;
 return intrinsicSuperViewContentSize ;
}

@end

Hope that's helpful to someone! Note that if you wanted padding on the top and bottom, you would need to change this lines:

UIEdgeInsets insets = {0, PADDING, 0, PADDING};

To this:

UIEdgeInsets insets = {PADDING, PADDING, PADDING, PADDING};

And add this line underneath the similar one for width:

intrinsicSuperViewContentSize.height += PADDING * 2 ;

You could put "element 2" in a smaller column (ie: col-2) and then use push on larger screens only:

<div class="row">
    <div class="col-lg-6 col-xs-6">elements 1</div>
    <div class="col-lg-6 col-xs-6">
      <div class="row">
       <div class="col-lg-2 col-lg-push-10 col-md-2 col-md-push-0 col-sm-2 col-sm-push-0 col-xs-2 col-xs-push-0">
         <div class="pull-right">elements 2</div>
       </div>
      </div>
    </div>
</div>

Demo: http://bootply.com/88095

Another option is to override the float of .pull-right using a @media query..

@media (max-width: 1200px) {
    .row .col-lg-6 > .pull-right {
        float: none !important;
    }
}

Lastly, another option is to create your own .pull-right-lg CSS class..

@media (min-width: 1200px) {
    .pull-right-lg {
        float: right;
    }
}

UPDATE

Bootstrap 4 includes responsive floats, so in this case you'd just use float-lg-right.
No extra CSS is needed.

Bootstrap 4 Demo

Open Notepad++
Select Replace (Ctrl/H)
Find what: \x00
Replace with:
Click on radio button Regular expression
Click on Replace All

make the image float: left; and the text float: right;

Take a look at this fiddle I used a picture online but you can just swap it out for your picture.

In openCV whenever you try to display an oversized image or image bigger than your display resolution you get the cropped display. It's a default behaviour.
In order to view the image in the window of your choice openCV encourages to use named window. Please refer to namedWindow documentation

The function namedWindow creates a window that can be used as a placeholder for images and trackbars. Created windows are referred to by their names.

cv.namedWindow(name, flags=CV_WINDOW_AUTOSIZE) where each window is related to image container by the name arg, make sure to use same name

eg:

import cv2
frame = cv2.imread('1.jpg')
cv2.namedWindow("Display 1")
cv2.resizeWindow("Display 1", 300, 300)
cv2.imshow("Display 1", frame)

you can use flex box for it.. this will solve your problem

.image-parent 
{
     height:33px; 
     display:flex; 
}

It downloads the (debug) symbols from the device, so it becomes possible to debug on devices with that specific iOS version and also to symbolicate crash reports that happened on that iOS version.

Since symbols are CPU specific, the above only works if you have imported the symbols not only for a specific iOS device but also for a specific CPU type. The currently CPU types needed are armv7 (e.g. iPhone 4, iPhone 4s), armv7s (e.g. iPhone 5) and arm64 (e.g. iPhone 5s).

So if you want to symbolicate a crash report that happened on an iPhone 5 with armv7s and only have the symbols for armv7 for that specific iOS version, Xcode won't be able to (fully) symbolicate the crash report.

If you're looking to make the elements be 33.3% only on small devices and lower:

This is backwards from what Bootstrap is designed for, but you can do this:

<div class="row">
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
</div>

This will make each element 33.3% wide on small and extra small devices but 100% wide on medium and larger devices.

JSFiddle: http://jsfiddle.net/jdwire/sggt8/embedded/result/

If you're only looking to hide elements for smaller devices:

I think you're looking for the visible-xs and/or visible-sm classes. These will let you make certain elements only visible to small screen devices.

For example, if you want a element to only be visible to small and extra-small devices, do this:

<div class="visible-xs visible-sm">You're using a fairly small device.</div>

To show it only for larger screens, use this:

<div class="hidden-xs hidden-sm">You're probably not using a phone.</div>

See http://getbootstrap.com/css/#responsive-utilities-classes for more information.

It may be because of you assigned more than 50 % RAM memory to your emulator.

Put the iframe inside the <p> and make the iframe CSS

float:left;

display:inline-block;

For any view, the frame and its content's sizes are the same ie if you have some content (e.g. image) with the size of 200 * 800 then its frame is also 200 * 800.

This is NOT true for scrollview's contents. The content is usually bigger than the frame size of the scrollView. If content is same in width, then you only scroll vertically. If it's same height then you only scroll horizontally. Hence it's the only view that needs 6 constraints not 4. For any other view having more than 4 required constraints will cause a conflict.

To setup your scroll view, its contents and position of scrolling, you basically need to answer three questions:

1. How big is my frame? ie at any given moment how big should the scrollview be? e.g. I only want to use half of the screen's height so

scrollview.frame = (x: 0, y:0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height / 2)

2. How much scrolling space do I need? ie How big is the content? e.g. the frame can be just 500 points of width, but then you can set an image with 7000 points, which would take quite some time to scroll horizontally. Or let it be exactly 500 points of width which then means no horizontal scrolling can happen.

3. How much have you scrolled at the moment? Say your content's (or image) width was 7000 and the frame size is just 500. To get to the end of the image, you'd need to scroll 6500 points to the right. The 3rd part really doesn't affect the constraints. You can ignore that for now. Understanding it just helps how a scrollView works.

Solution

Basically if you leave out the 2 extra constraints (about the content size) then the layout engine will complain due to the ambiguity. It won't know what area of the content is hidden (not visible in the scrollView) and what area of the content is not (visible in scrollView) hidden.

So make sure you add size constraints for the content as well

But some times I don't add size constraints to my views and it just works. Why is that?

If all the contents you've added into the scrollview are constrained to the edges of the scrollview, then as the content grow the scrollview will add space to accommodate. It's just that you might be using UIViews where its intrinsicContentSize is 0 so the scrollView will still complain about ambiguity of its content. However if you've used a UILabel and it has a non-empty text, then its intrinsicContentSize is set (based on Font size and text length and line breaks, etc) so the scrollView won't complain about its ambiguity.

Same issue happened with me when i mistakenly added some text in front of the top directive of the master page all the controls across all the page included in my project started showing, does not exist in the current context. After spending much time across the forum and self analysis, i found the mistakenly added text and removed but it does not solved the problem. Then i had to click on each error to open the associated page so that VS can load the page and recognize it, once the code was loaded in VS, error from those particular page started disappearing because VS recognized it. clicking on each error, loading each page in VS editor did the trick for me and you have to do it only once because later it will be automatically recognized by VS. I would say it is a Visual Studio Glitch.

A related question has been asked before: What is “above-the-fold content” in Google Pagespeed?

Firstly you have to notice that this is all about 'mobile pages'.
So when I interpreted your question and screenshot correctly, then this is not for your site!

On the contrary - doing some of the things advised by Google in their guidelines will things make worse than better for 'normal' websites.
And not everything that comes from Google is the "holy grail" just because it comes from Google. And they themselves are not a good role model if you have a look at their HTML markup.

The best advice I could give you is:

• Set width and height on replaced elements in your CSS, so that the browser can layout the elements and doesn't have to wait for the replaced content!

Additionally why do you use different CSS files, rather than just one?
The additional request is worse than the small amount of data volume. And after the first request the CSS file is cached anyway.

The things one should always take care of are:

• reduce the number of requests as much as possible
• keep your overall page weight as low as possible

And don't puzzle your brain about how to get 100% of Google's PageSpeed Insights tool ...! ;-)

Addition 1: Here is the page on which Google shows us, what they recommend for Optimize CSS Delivery.

As said before, I don't think that this is neither realistic nor that it makes sense for a "normal" website! Because mainly when you have a responsive web design it is most certain that you use media queries and other layout styles. So if you are not gonna load your CSS first and in a blocking manner you'll get a FOUT (Flash Of Unstyled Text). I really do not believe that this is "better" than at least some more milliseconds to render the page!

Imho Google is starting a new "hype" (when I have a look at all the question about it here on Stackoverflow) ...!

Same issue, but I just cleared my settings. I went into Settings > Preferences and Clicked [Restore defaults and reload]. Just remember what your settings were.

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

You just need to set the table cell padding to zero. Here's a jsfiddle (using Bootstrap 2.3.2) with your code slightly modified:

This code works perfect if you need to see the brand centered and with auto width in toolbar. It contains the Wordpress function to get the image file from right path:

<a class="navbar-brand page-scroll" rel="home" 
    href="#page-top"  title="Title">
    <img style="height: 100%; width: auto;" 
          src="<?php echo get_template_directory_uri();?>/img/logo.png">

here is one line code

name = (city.getName() != null) ? city.getName() : "N/A";

here is example how it work, run below code in js file and understand the result. This ("Data" != null) is condition as we do in normal if() and "Data" is statement when this condition became true. this " : " act as else and "N/A" is statement for else condition. Hope this help you to understand the logic.

name = ("Data" != null) ? "Data" : "N/A";_x000D_

console.log(name);

A common way to approach this is to add your own ForEach generic method on IEnumerable<T>. Here's the one we've got in MoreLINQ:

public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)
{
    source.ThrowIfNull("source");
    action.ThrowIfNull("action");
    foreach (T element in source)
    {
        action(element);
    }
}

(Where ThrowIfNull is an extension method on any reference type, which does the obvious thing.)

It'll be interesting to see if this is part of .NET 4.0. It goes against the functional style of LINQ, but there's no doubt that a lot of people find it useful.

Once you've got that, you can write things like:

people.Where(person => person.Age < 21)
      .ForEach(person => person.EjectFromBar());

I checked the answer however, (for each) in PHP is deprecated and no longer work with the latest php versions.

Usually we would convert an array into a string to log it somewhere, perhaps debugging or test etc.

I would convert the array into a string by doing:

$Output = implode(",", $SourceArray);

Whereas:

$output is the result (where the string would be generated

",": is the separator (between each array field

$SourceArray: is your source array.

I hope this helps

The classes for the OOXML file formats (such as XSSF for .xlsx) are in a different Jar file. You need to include the poi-ooxml jar in your project, along with the dependencies for it

You can get a list of all the components and their dependencies on the POI website here.

What you probably want to do is download the 3.11 binary package, grab the poi-ooxml jar from it, and the dependencies in the ooxml-lib directory. Import these into your project and you'll be sorted.

Alternately, if you use Maven, you can see here for the list of the artificats you'll want to depend on, but it'd want to be something like:

<dependency>
   <groupId>org.apache.poi</groupId>
   <artifactId>poi-ooxml</artifactId>
   <version>3.11</version>
</dependency>

The poi-ooxml maven dependency will pull in the main POI jar and the dependencies for you automatically. If you want to work with the non-spreadsheet formats, you'd also want to depend on the poi-scratchpad artifact too, as detailed on the POI components page

You could try this: it's a very good tool, very fast and effective.

This one will only match the input field or string if there are no spaces. If there are any spaces, it will not match at all.

/^([A-z0-9!@#$%^&*().,<>{}[\]<>?_=+\-|;:\'\"\/])*[^\s]\1*$/

Matches from the beginning of the line to the end. Accepts alphanumeric characters, numbers, and most special characters.

If you want just alphanumeric characters then change what is in the [] like so:

/^([A-z])*[^\s]\1*$/

Another option, using the command module:

- name: Create file
  command: touch /path/to/file
  args:
    creates: /path/to/file

The 'creates' argument ensures that this action is not performed if the file exists.

Let PowerShell analyze and decide the data type. It internally uses a 'Variant' for this.

And generally it does a good job...

param($x)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
    $iTunes.PlayerPosition = $iTunes.PlayerPosition + $x
}

Or if you need to pass multiple parameters:

param($x1, $x2)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
    $iTunes.PlayerPosition = $iTunes.PlayerPosition + $x1
    $iTunes.<AnyProperty>  = $x2
}

Just in case someone stumbles upon this like I did and doesn't realise, the two variations above are for different use cases.

The following:

.blue-border, .background {
    border: 1px solid #00f;
    background: #fff;
}

is for when you want to add styles to elements that have either the blue-border or background class, for example:

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

would all get a blue border and white background applied to them.

However, the accepted answer is different.

.blue-border.background {
    border: 1px solid #00f;
    background: #fff;
}

This applies the styles to elements that have both classes so in this example only the <div> with both classes should get the styles applied (in browsers that interpret the CSS properly):

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

So basically think of it like this, comma separating applies to elements with one class OR another class and dot separating applies to elements with one class AND another class.

I wrote a cross-platform library color_ostream for this, with the support of ANSI color, 256 color and true color, all you have to do is directly including it and changing cout to rd_cout like this.
| std | basic color | 256 color | true color | | :----: | :----: | :----: | :----: | | std::cout | color_ostream::rd_cout | color_ostream::rd256_cout | color_ostream::rdtrue_cout | | std::wcout | color_ostream::rd_wcout | color_ostream::rd256_wcout | color_ostream::rdtrue_wcout | | std::cerr | color_ostream::rd_cerr | color_ostream::rd256_cerr | color_ostream::rdtrue_cerr | | std::wcerr | color_ostream::rd_wcerr | color_ostream::rd256_wcerr | color_ostream::rdtrue_wcerr | | std::clog | color_ostream::rd_clog | color_ostream::rd256_clog | color_ostream::rdtrue_clog | | std::wclog | color_ostream::rd_wclog | color_ostream::rd256_wclog | color_ostream::rdtrue_wclog |
Here is an simple example:

//hello.cpp
#include "color_ostream.h"

using namespace color_ostream;

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[]) {
    rd_wcout.imbue(std::locale(std::locale(),"",LC_CTYPE));
    rd_wcout << L"Hello world\n";
    rd_wcout << L"Hola Mundo\n";
    rd_wcout << L"Bonjour le monde\n";

    rd256_wcout << L"\n256 color" << std::endl;
    rd256_wcout << L"Hello world\n";
    rd256_wcout << L"Hola Mundo\n";
    rd256_wcout << L"Bonjour le monde\n";

    rdtrue_wcout << L"\ntrue color" << std::endl;
    rdtrue_wcout << L"Hello world\n";
    rdtrue_wcout << L"Hola Mundo\n";
    rdtrue_wcout << L"Bonjour le monde\n";
    return 0;
}

I've had this happen on VS after I changed the file's line endings. Changing them back to Windows CR LF fixed the issue.

Some additional advice for Windows(10) users:

1. If you are using Anaconda Prompt/PowerShell for the first time, type "Anaconda" in the search field of your Windows task bar and you will see the suggested software.
2. Make sure to open the Anaconda prompt as administrator.
3. Always navigate to your user directory or the directory with your Jupyter Notebook files first before running the command. Otherwise you might end up somewhere in your system files and be confused by an unfamiliar file tree.

The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:

(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

The nohup command only writes to nohup.out if the output would otherwise go to the terminal. If you have redirected the output of the command somewhere else - including /dev/null - that's where it goes instead.

 nohup command >/dev/null 2>&1   # doesn't create nohup.out

If you're using nohup, that probably means you want to run the command in the background by putting another & on the end of the whole thing:

 nohup command >/dev/null 2>&1 & # runs in background, still doesn't create nohup.out

On Linux, running a job with nohup automatically closes its input as well. On other systems, notably BSD and macOS, that is not the case, so when running in the background, you might want to close input manually. While closing input has no effect on the creation or not of nohup.out, it avoids another problem: if a background process tries to read anything from standard input, it will pause, waiting for you to bring it back to the foreground and type something. So the extra-safe version looks like this:

nohup command </dev/null >/dev/null 2>&1 & # completely detached from terminal 

Note, however, that this does not prevent the command from accessing the terminal directly, nor does it remove it from your shell's process group. If you want to do the latter, and you are running bash, ksh, or zsh, you can do so by running disown with no argument as the next command. That will mean the background process is no longer associated with a shell "job" and will not have any signals forwarded to it from the shell. (Note the distinction: a disowned process gets no signals forwarded to it automatically by its parent shell - but without nohup, it will still receive a HUP signal sent via other means, such as a manual kill command. A nohup'ed process ignores any and all HUP signals, no matter how they are sent.)

Explanation:

In Unixy systems, every source of input or target of output has a number associated with it called a "file descriptor", or "fd" for short. Every running program ("process") has its own set of these, and when a new process starts up it has three of them already open: "standard input", which is fd 0, is open for the process to read from, while "standard output" (fd 1) and "standard error" (fd 2) are open for it to write to. If you just run a command in a terminal window, then by default, anything you type goes to its standard input, while both its standard output and standard error get sent to that window.

But you can ask the shell to change where any or all of those file descriptors point before launching the command; that's what the redirection (<, <<, >, >>) and pipe (|) operators do.

The pipe is the simplest of these... command1 | command2 arranges for the standard output of command1 to feed directly into the standard input of command2. This is a very handy arrangement that has led to a particular design pattern in UNIX tools (and explains the existence of standard error, which allows a program to send messages to the user even though its output is going into the next program in the pipeline). But you can only pipe standard output to standard input; you can't send any other file descriptors to a pipe without some juggling.

The redirection operators are friendlier in that they let you specify which file descriptor to redirect. So 0<infile reads standard input from the file named infile, while 2>>logfile appends standard error to the end of the file named logfile. If you don't specify a number, then input redirection defaults to fd 0 (< is the same as 0<), while output redirection defaults to fd 1 (> is the same as 1>).

Also, you can combine file descriptors together: 2>&1 means "send standard error wherever standard output is going". That means that you get a single stream of output that includes both standard out and standard error intermixed with no way to separate them anymore, but it also means that you can include standard error in a pipe.

So the sequence >/dev/null 2>&1 means "send standard output to /dev/null" (which is a special device that just throws away whatever you write to it) "and then send standard error to wherever standard output is going" (which we just made sure was /dev/null). Basically, "throw away whatever this command writes to either file descriptor".

When nohup detects that neither its standard error nor output is attached to a terminal, it doesn't bother to create nohup.out, but assumes that the output is already redirected where the user wants it to go.

The /dev/null device works for input, too; if you run a command with </dev/null, then any attempt by that command to read from standard input will instantly encounter end-of-file. Note that the merge syntax won't have the same effect here; it only works to point a file descriptor to another one that's open in the same direction (input or output). The shell will let you do >/dev/null <&1, but that winds up creating a process with an input file descriptor open on an output stream, so instead of just hitting end-of-file, any read attempt will trigger a fatal "invalid file descriptor" error.

What does shapiro.test do?

shapiro.test tests the Null hypothesis that "the samples come from a Normal distribution" against the alternative hypothesis "the samples do not come from a Normal distribution".

How to perform shapiro.test in R?

The R help page for ?shapiro.test gives,

x - a numeric vector of data values. Missing values are allowed, 
    but the number of non-missing values must be between 3 and 5000.

That is, shapiro.test expects a numeric vector as input, that corresponds to the sample you would like to test and it is the only input required. Since you've a data.frame, you'll have to pass the desired column as input to the function as follows:

> shapiro.test(heisenberg$HWWIchg)
#   Shapiro-Wilk normality test

# data:  heisenberg$HWWIchg 
# W = 0.9001, p-value = 0.2528

Interpreting results from shapiro.test:

First, I strongly suggest you read this excellent answer from Ian Fellows on testing for normality.

As shown above, the shapiro.test tests the NULL hypothesis that the samples came from a Normal distribution. This means that if your p-value <= 0.05, then you would reject the NULL hypothesis that the samples came from a Normal distribution. As Ian Fellows nicely put it, you are testing against the assumption of Normality". In other words (correct me if I am wrong), it would be much better if one tests the NULL hypothesis that the samples do not come from a Normal distribution. Why? Because, rejecting a NULL hypothesis is not the same as accepting the alternative hypothesis.

In case of the null hypothesis of shapiro.test, a p-value <= 0.05 would reject the null hypothesis that the samples come from normal distribution. To put it loosely, there is a rare chance that the samples came from a normal distribution. The side-effect of this hypothesis testing is that this rare chance happens very rarely. To illustrate, take for example:

set.seed(450)
x <- runif(50, min=2, max=4)
shapiro.test(x)
#   Shapiro-Wilk normality test
# data:  runif(50, min = 2, max = 4) 
# W = 0.9601, p-value = 0.08995

So, this (particular) sample runif(50, min=2, max=4) comes from a normal distribution according to this test. What I am trying to say is that, there are many many cases under which the "extreme" requirements (p < 0.05) are not satisfied which leads to acceptance of "NULL hypothesis" most of the times, which might be misleading.

Another issue I'd like to quote here from @PaulHiemstra from under comments about the effects on large sample size:

An additional issue with the Shapiro-Wilk's test is that when you feed it more data, the chances of the null hypothesis being rejected becomes larger. So what happens is that for large amounts of data even very small deviations from normality can be detected, leading to rejection of the null hypothesis event though for practical purposes the data is more than normal enough.

Although he also points out that R's data size limit protects this a bit:

Luckily shapiro.test protects the user from the above described effect by limiting the data size to 5000.

If the NULL hypothesis were the opposite, meaning, the samples do not come from a normal distribution, and you get a p-value < 0.05, then you conclude that it is very rare that these samples do not come from a normal distribution (reject the NULL hypothesis). That loosely translates to: It is highly likely that the samples are normally distributed (although some statisticians may not like this way of interpreting). I believe this is what Ian Fellows also tried to explain in his post. Please correct me if I've gotten something wrong!

@PaulHiemstra also comments about practical situations (example regression) when one comes across this problem of testing for normality:

In practice, if an analysis assumes normality, e.g. lm, I would not do this Shapiro-Wilk's test, but do the analysis and look at diagnostic plots of the outcome of the analysis to judge whether any assumptions of the analysis where violated too much. For linear regression using lm this is done by looking at some of the diagnostic plots you get using plot(lm()). Statistics is not a series of steps that cough up a few numbers (hey p < 0.05!) but requires a lot of experience and skill in judging how to analysis your data correctly.

Here, I find the reply from Ian Fellows to Ben Bolker's comment under the same question already linked above equally (if not more) informative:

For linear regression,

1. Don't worry much about normality. The CLT takes over quickly and if you have all but the smallest sample sizes and an even remotely reasonable looking histogram you are fine.

2. Worry about unequal variances (heteroskedasticity). I worry about this to the point of (almost) using HCCM tests by default. A scale location plot will give some idea of whether this is broken, but not always. Also, there is no a priori reason to assume equal variances in most cases.

3. Outliers. A cooks distance of > 1 is reasonable cause for concern.

Those are my thoughts (FWIW).

Hope this clears things up a bit.

I was having a similar error, it seems that the compiler misunderstand the call to the constructor without arguments. I made it work by removing the parenthesis from the variable declaration, in your code something like this:

class Foo
{
  public:
    Foo() {};
    Foo(int a) {};
    void bar() {};
};

int main()
{
  // this works...
  Foo foo1(1);
  foo1.bar();

  // this does not...
  Foo foo2; // Without "()" 
  foo2.bar();

  return 0;
}

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

This should do the trick:

public int getNumberOfPdfPages(string fileName)
{
    using (StreamReader sr = new StreamReader(File.OpenRead(fileName)))
    {
        Regex regex = new Regex(@"/Type\s*/Page[^s]");
        MatchCollection matches = regex.Matches(sr.ReadToEnd());

        return matches.Count;
    }
}

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

Casting to an int truncates the value. Adding 0.5 causes it to do proper rounding.

int y = (int)(x + 0.5);

The sum function only gets the total of a column. In order to sum two values from different columns, convert the values to int and add them up using the +-Operator

Select (convert(int, col1)+convert(int, col2)) as summed from tbl1

Hope that helps.

To manually generate a Certificate, you need a Certificate Signing Request (CSR) file from your Mac. To create a CSR file, follow the instructions below to create one using Keychain Access.

Create a CSR file. In the Applications folder on your Mac, open the Utilities folder and launch Keychain Access.

Within the Keychain Access drop down menu, select Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority.

In the Certificate Information window, enter the following information: In the User Email Address field, enter your email address. In the Common Name field, create a name for your private key (e.g., John Doe Dev Key). The CA Email Address field should be left empty. In the "Request is" group, select the "Saved to disk" option. Click Continue within Keychain Access to complete the CSR generating process.

Please see my answer below, inspired by answers above but a bit more detailed...

// Get The Json Response (With Try Catch)
try {

    String s = null;

    if (response.body() != null) {

        s = response.body().string();

        JSONObject json = null;

For windows just do this:

import os
os.system("color 01")
print('hello friends')

Where it says "01" that is saying background black, and text color blue. Go into CMD Prompt and type color help for a list of colors.

Another approach would be to use a NOT EXISTS condition in your join condition to test for later purchases:

SELECT *
FROM customer c
LEFT JOIN purchase p ON (
       c.id = p.customer_id
   AND NOT EXISTS (
     SELECT 1 FROM purchase p1
     WHERE p1.customer_id = c.id
     AND p1.id > p.id
   )
)

Andy's answer helps but if you have concern on exposing your database password in your django setting, I suggest to follow django official configuration on mysql connection: https://docs.djangoproject.com/en/1.7/ref/databases/

Quoted here as:

# settings.py
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'OPTIONS': {
            'read_default_file': '/path/to/my.cnf',
        },
    }
}


# my.cnf
[client]
database = NAME
user = USER
password = PASSWORD
default-character-set = utf8

To replace 'HOST': '127.0.0.1' in setting, simply add it in my.cnf:

# my.cnf
[client]
database = NAME
host = HOST NAME or IP
user = USER
password = PASSWORD
default-character-set = utf8

Another OPTION that is useful, is to set your storage engine for django, you might want it in your setting.py:

'OPTIONS': {
   'init_command': 'SET storage_engine=INNODB',
}

In a conda environment, this is what solved my problem (I was missing cudart64-100.dll:

1. Downloaded it from dll-files.com/CUDART64_100.DLL

2. Put it in my conda environment at C:\Users\<user>\Anaconda3\envs\<env name>\Library\bin

That's all it took! You can double check if it's working:

import tensorflow as tf
tf.config.experimental.list_physical_devices('GPU')

I experienced this issue when calling my web api endpoint and solved it.

In my case it was an issue in the way the client was encoding the body content. I was not specifying the encoding or media type. Specifying them solved it.

Not specifying encoding type, caused 415 error:

var content = new StringContent(postData);
httpClient.PostAsync(uri, content);

Specifying the encoding and media type, success:

var content = new StringContent(postData, Encoding.UTF8, "application/json");
httpClient.PostAsync(uri, content);

Here is a simple Windows bat file to split incoming file into 50 parts. Each part has length 1 minute. Sorry for such dumb script. I hope it is better to have a dumb windows script instead of do not have it at all. Perhaps it help someone. (Based on "bat file for loop" from this site.)

Java doesn't have associative arrays like PHP does.

There are various solutions for what you are doing, such as using a Map, but it depends on how you want to look up the information. You can easily write a class that holds all your information and store instances of them in an ArrayList.

public class Foo{
    public String name, fname;

    public Foo(String name, String fname){
        this.name = name;
        this.fname = fname;
    }
}

And then...

List<Foo> foos = new ArrayList<Foo>();
foos.add(new Foo("demo","fdemo"));
foos.add(new Foo("test","fname"));

So you can access them like...

foos.get(0).name;
=> "demo"

You can search column before assignments:

Dim col_n as long
for i = 1 to NumCols
    if Cells(1, i).Value = "column header you are looking for" Then col_n = i
next

for i = 1 to NumRows
    Cells(i, col_n).Value = "PHEV"
next i

The most recent solution is right. You are reading solutions as a string, in which case the order is 1, then 100, then 104 followed by 2 then 21, then 2001001010, 3 and so forth.

You have to CAST your input as an int instead:

sorted strings:

stringList = (1, 10, 2, 21, 3)

sorted ints:

intList = (1, 2, 3, 10, 21)

To cast, just put the stringList inside int ( blahblah ).

Again:

stringList = (1, 10, 2, 21, 3)

newList = int (stringList)

print newList

=> returns (1, 2, 3, 10, 21) 

Whilst it is NOT possible to use HTML to format your email body you can add line breaks as has been previously suggested.

If you are able to use javascript then "encodeURIComponent()" might be of use like below...

var formattedBody = "FirstLine \n Second Line \n Third Line";
var mailToLink = "mailto:[email protected]?body=" + encodeURIComponent(formattedBody);
window.location.href = mailToLink;

Another option:

var dateTime = new Date();
var minutesTwoDigitsWithLeadingZero = ("0" + dateTime.getMinutes()).substr(-2);

I realize I'm late to the game, but here's a slightly Yum-style (Red Hat) one I wrote (not going for 100% accuracy here, but if you're using a progress bar for that level of accuracy, then you're WRONG anyway):

import sys

def cli_progress_test(end_val, bar_length=20):
    for i in xrange(0, end_val):
        percent = float(i) / end_val
        hashes = '#' * int(round(percent * bar_length))
        spaces = ' ' * (bar_length - len(hashes))
        sys.stdout.write("\rPercent: [{0}] {1}%".format(hashes + spaces, int(round(percent * 100))))
        sys.stdout.flush()

Should produce something looking like this:

Percent: [##############      ] 69%

... where the brackets stay stationary and only the hashes increase.

This might work better as a decorator. For another day...

Actually, I just figured it out:

In [20]: some_list[::len(some_list) - 1]
Out[20]: ['1', 'F']

You can't implicitly return with an if, you would need the braces:

let adults = family.filter(person => { if (person.age > 18) return person} );

It can be simplified though:

let adults = family.filter(person => person.age > 18);

@sarath how to overwrite the file if i want to run another select * command from a different table and write to same file ?

INSERT OVERWRITE LOCAL DIRECTORY '/home/training/mydata/outputs' SELECT expl , count(expl) as total
FROM ( SELECT explode(splits) as expl FROM ( SELECT split(words,' ') as splits FROM wordcount ) t2 ) t3 GROUP BY expl ;

This is an example to sarath's question

the above is a word count job stored in outputs file which is in local directory :)

Apart of directly writing HTML on the PrintWriter obtained from the response (which is the standard way of outputting HTML from a Servlet), you can also include an HTML fragment contained in an external file by using a RequestDispatcher:

public void doGet(HttpServletRequest request,
       HttpServletResponse response)
       throws IOException, ServletException {
   response.setContentType("text/html");
   PrintWriter out = response.getWriter();
   out.println("HTML from an external file:");     
   request.getRequestDispatcher("/pathToFile/fragment.html")
          .include(request, response); 
   out.close();
}

select to.chargeid,t0.po,i.chargetype from invoice i
inner join
(select chargeid,max(servicemonth)po from invoice 
group by chargeid)t0
on i.chargeid=t0.chargeid

The above query will work if the distinct charge id has different chargetype combinations.Hope this simple query helps with little performance time into consideration...

Your question almost spells the SQL for this:

DELETE FROM table WHERE id IN (1, 4, 6, 7)

In my case, I got this when trying to run Django tests through PyCharm. I think it is because PyCharm does not load the initial Django project settings, i.e. those that manage.py shell runs initially. One can add them to the start of the testing script or just run the tests using manage.py test.

Versions:

• Python 3.5 (in virtualenv)
• PyCharm 2016.3.2 Professional
• Django 1.10

A more complete answer would be it is not possible with ftp(at least the ftp program installed on centos 6).

Since you wanted an un-attended process, "pts"'s answer will work fine.

Do the unattended upload with curl instead of ftp:

curl -u user:password -T file ftp://server/dir/file

%40 doesn't appear to work.

[~]# ftp domain.com
ftp: connect: Connection refused
ftp> quit
[~]# ftp some_user%[email protected]
ftp: some_user%[email protected]: Name or service not known
ftp> quit

All I've got is to open the ftp program and use the domain and enter the user when asked. Usually, a password is required anyway, so the interactive nature probably isn't problematic.

[~]# ftp domain.com

You can add below answer to your _variable.scss file, no need to change the other outline or any thing. I'm sure this will work.

If you're curious which protocols .NET supports, you can try HttpClient out on https://www.howsmyssl.com/

// set proxy if you need to
// WebRequest.DefaultWebProxy = new WebProxy("http://localhost:3128");

File.WriteAllText("howsmyssl-httpclient.html", new HttpClient().GetStringAsync("https://www.howsmyssl.com").Result);

// alternative using WebClient for older framework versions
// new WebClient().DownloadFile("https://www.howsmyssl.com/", "howsmyssl-webclient.html");

The result is damning:

Your client is using TLS 1.0, which is very old, possibly susceptible to the BEAST attack, and doesn't have the best cipher suites available on it. Additions like AES-GCM, and SHA256 to replace MD5-SHA-1 are unavailable to a TLS 1.0 client as well as many more modern cipher suites.

As Eddie explains above, you can enable better protocols manually:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11; 

I don't know why it uses bad protocols out-the-box. That seems a poor setup choice, tantamount to a major security bug (I bet plenty of applications don't change the default). How can we report it?

I get this post is old but there have been changes to how select2 works now and the answer to this question is extremely simple.

To set the values in a multi select2 is as follows

$('#Books_Illustrations').val([1,2,3]).change();

There is no need to specify .select2 in jquery anymore, simply .val

Also there will be times you will not want to fire the change event because you might have some other code that will execute which is what will happen if you use the method above so to get around that you can change the value without firing the change event like so

$('#Books_Illustrations').select2([1,2,3], null, false);

In the interface, you specify the property:

public interface IResourcePolicy
{
   string Version { get; set; }
}

In the implementing class, you need to implement it:

public class ResourcePolicy : IResourcePolicy
{
   public string Version { get; set; }
}

This looks similar, but it is something completely different. In the interface, there is no code. You just specify that there is a property with a getter and a setter, whatever they will do.

In the class, you actually implement them. The shortest way to do this is using this { get; set; } syntax. The compiler will create a field and generate the getter and setter implementation for it.

If you're working with a BitmapSource:

var resizedBitmap = new TransformedBitmap(
    bitmapSource,
    new ScaleTransform(scaleX, scaleY));

If you want finer control over quality, run this first:

RenderOptions.SetBitmapScalingMode(
    bitmapSource,
    BitmapScalingMode.HighQuality);

(Default is BitmapScalingMode.Linear which is equivalent to BitmapScalingMode.LowQuality.)

This could help: http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=EURUSD=X,GBPUSD=X It will return csv file:

"EUR",1.2972
"GBP",1.6034

Or if you need json: Yahoo csv parser

Word of caution when coding with Visual Studio (2013)

I have wasted 4 to 5 hours trying to debug this error. I tried all the solutions that I found on StackOverflow by the letter and I still got this error: Can't bind to 'routerlink' since it isn't a known native property

Be aware, Visual Studio has the nasty habit of autoformatting text when you copy/paste code. I always got a small instantaneous adjustment from VS13 (camel case disappears).

This:

<div>
    <a [routerLink]="['/catalog']">Catalog</a>
    <a [routerLink]="['/summary']">Summary</a>
</div>

Becomes:

<div>
    <a [routerlink]="['/catalog']">Catalog</a>
    <a [routerlink]="['/summary']">Summary</a>
</div>

It's a small difference, but enough to trigger the error. The ugliest part is that this small difference just kept avoiding my attention every time I copied and pasted. By sheer chance, I saw this small difference and solved it.

You get the cursor position by calling GetCursorPos.

POINT p;
if (GetCursorPos(&p))
{
    //cursor position now in p.x and p.y
}

This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.

if (ScreenToClient(hwnd, &p))
{
    //p.x and p.y are now relative to hwnd's client area
}

You hide and show the cursor with ShowCursor.

ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again

You must ensure that every call to hide the cursor is matched by one that shows it again.

You can also select multiple files like this

git add folder/subfolder/*

This will add all the files in the specified subfolder. Very useful when you edit a bunch of files but you just want to commit some of them...

You can try with Picasso, it's really nice and easy. Don't forget to add the permissions in the manifest.

Picasso.with(context)
                     .load("http://ImageURL")
                     .resize(width,height)
                     .into(imageView );

You can also take a look at a tutorial here : Youtube / Github

Set your Textbox value in a string like:

string MySTring = textBox1.Text;

Then replace your string. For example, replace "Text" with "Hex":

MyString = MyString.Replace("Text", "Hex");

Or for your problem (replace "," with ;) :

MyString = MyString.Replace(@""",""", ",");

Note: If you have "" in your string you have to use @ in the back of "", like:

@"","";

In Chrome 8 the path is always 'C:\fakepath\' with the correct file name.

Edit: Hash versus Array

As cincodenada correctly pointed out in the comment, ysth gave a better answer: I should have answered your question with another question: "Do you really want to use a Perl array? A hash may be more appropriate."

An array allocates memory for all possible indices up to the largest used so-far. In your example, you allocate 24 cells (but use only 3). By contrast, a hash only allocates space for those fields that are actually used.

Array solution: scalar grep

Here are two possible solutions (see below for explanation):

print scalar(grep {defined $_} @a), "\n";  # prints 3
print scalar(grep $_, @a), "\n";            # prints 3

Explanation: After adding $a[23], your array really contains 24 elements --- but most of them are undefined (which also evaluates as false). You can count the number of defined elements (as done in the first solution) or the number of true elements (second solution).

What is the difference? If you set $a[10]=0, then the first solution will count it, but the second solution won't (because 0 is false but defined). If you set $a[3]=undef, none of the solutions will count it.

Hash solution (by yst)

As suggested by another solution, you can work with a hash and avoid all the problems:

$a{0}  = 1;
$a{5}  = 2;
$a{23} = 3;
print scalar(keys %a), "\n";  # prints 3

This solution counts zeros and undef values.

I know this topic is a bit old, but I think I did something that may be useful for someone, so I'm posting it.

I compiled suggestions from this thread's answers into a procedure:

CREATE OR REPLACE PROCEDURE create_table_if_doesnt_exist(
  p_table_name VARCHAR2,
  create_table_query VARCHAR2
) AUTHID CURRENT_USER IS
  n NUMBER;
BEGIN
  SELECT COUNT(*) INTO n FROM user_tables WHERE table_name = UPPER(p_table_name);
  IF (n = 0) THEN
    EXECUTE IMMEDIATE create_table_query;
  END IF;
END;

You can then use it in a following way:

call create_table_if_doesnt_exist('my_table', 'CREATE TABLE my_table (
        id NUMBER(19) NOT NULL PRIMARY KEY,
        text VARCHAR2(4000),
        modified_time TIMESTAMP
  )'
);

I know that it's kinda redundant to pass table name twice, but I think that's the easiest here.

Hope somebody finds above useful :-).

I follow it extremely rigorously. The only god before PEP-8 is existing code bases.

Use:

select * from mytest
EXEC sp_rename 'mytest.eid', 'id', 'COLUMN'
alter table mytest add id int not null identity(1,1)
update mytset set eid=id
ALTER TABLE mytest DROP COLUMN eid

ALTER TABLE [dbo].[yourtablename] ADD DEFAULT (getdate()) FOR [yourfieldname]

It's working 100%.

TypeError for Slice Notation str[a:b]

tl;dr: use a colon : instead of a comma in between the two indices a and b in str[a:b]

When working with strings and slice notation (a common sequence operation), it can happen that a TypeError is raised, pointing out that the indices must be integers, even if they obviously are.

Example

>>> my_string = "hello world"
>>> my_string[0,5]
TypeError: string indices must be integers

We obviously passed two integers for the indices to the slice notation, right? So what is the problem here?

This error can be very frustrating - especially at the beginning of learning Python - because the error message is a little bit misleading.

Explanation

We implicitly passed a tuple of two integers (0 and 5) to the slice notation when we called my_string[0,5] because 0,5 (even without the parentheses) evaluates to the same tuple as (0,5) would do.

A comma , is actually enough for Python to evaluate something as a tuple:

>>> my_variable = 0,
>>> type(my_variable)
<class 'tuple'>

So what we did there, this time explicitly:

>>> my_string = "hello world"
>>> my_tuple = 0, 5
>>> my_string[my_tuple]
TypeError: string indices must be integers

Now, at least, the error message makes sense.

Solution

We need to replace the comma , with a colon : to separate the two integers correctly:

>>> my_string = "hello world"
>>> my_string[0:5]
'hello'

A clearer and more helpful error message could have been something like:

TypeError: string indices must be integers (not tuple)

A good error message shows the user directly what they did wrong and it would have been more obvious how to solve the problem.

[So the next time when you find yourself responsible for writing an error description message, think of this example and add the reason or other useful information to error message to let you and maybe other people understand what went wrong.]

Lessons learned

• slice notation uses colons : to separate its indices (and step range, e.g. str[from:to:step])
• tuples are defined by commas , (e.g. t = 1,)
• add some information to error messages for users to understand what went wrong

Cheers and happy programming
winklerrr

[I know this question was already answered and this wasn't exactly the question the thread starter asked, but I came here because of the above problem which leads to the same error message. At least it took me quite some time to find that little typo.

So I hope that this will help someone else who stumbled upon the same error and saves them some time finding that tiny mistake.]

You can use binary literals. They are standardized in C++14. For example,

int x = 0b11000;

Support in GCC

Support in GCC began in GCC 4.3 (see https://gcc.gnu.org/gcc-4.3/changes.html) as extensions to the C language family (see https://gcc.gnu.org/onlinedocs/gcc/C-Extensions.html#C-Extensions), but since GCC 4.9 it is now recognized as either a C++14 feature or an extension (see Difference between GCC binary literals and C++14 ones?)

Support in Visual Studio

Support in Visual Studio started in Visual Studio 2015 Preview (see https://www.visualstudio.com/news/vs2015-preview-vs#C++).

@marius

Yes, you can use several namespaces at a time, eg:

using namespace boost;   
using namespace std;  

shared_ptr<int> p(new int(1));   // shared_ptr belongs to boost   
cout << "cout belongs to std::" << endl;   // cout and endl are in std

[Feb. 2014 -- (Has it really been that long?): This particular example is now ambiguous, as Joey points out below. Boost and std:: now each have a shared_ptr.]

in your view blade change to

{{ Form::open(['action' => 'postcontroller@edit', 'method' => 'PUT', 'class' = 'your class here']) }}

</div>

<div>
{{ Form::submit('Update', ['class' => 'btn class here'])}}
</div>

{{ Form::close() }}

actually you can use raw form like your question. but i dont recomended it. dan itulah salah satu alasan agan belajar framework, simple, dan cepat. so kenapa pake raw form kalo ada yang lebih mudah. hehe. proud to be indonesian.

You can either Drop the columns you do not need OR Select the ones you need

# Using DataFrame.drop
df.drop(df.columns[[1, 2]], axis=1, inplace=True)

# drop by Name
df1 = df1.drop(['B', 'C'], axis=1)

# Select the ones you want
df1 = df[['a','d']]

Add the following 2 lines

var regex = new Regex(Regex.Escape(","));
sb_trim = regex.Replace(sb_trim, " ", 1);

If sb_trim= John,Smith,100000,M the above code will return "John Smith,100000,M"

Checkout zirafa/bootstrap-grid-only. It contains only the bootstrap grid and responsive utilities that you need (no reset or anything), and simplifies the complexity of working directly with the LESS files.

The error means that the string you're trying to parse an integer from doesn't actually contain a valid integer.

It's extremely unlikely that the text boxes will contain a valid integer immediately when the form is created - which is where you're getting the integer values. It would make much more sense to update a and b in the button click events (in the same way that you are in the constructor). Also, check out the Int.TryParse method - it's much easier to use if the string might not actually contain an integer - it doesn't throw an exception so it's easier to recover from.

Since 2017 Wikipedia provides a REST API with better caching. In the documentation you can find the following API which perfectly fits your use case. (as it is used by the new Page Previews feature)

https://en.wikipedia.org/api/rest_v1/page/summary/Stack_Overflow returns the following data which can be used to display a summery with a small thumbnail:

Use Blazor http://learn-blazor.com/architecture/interop/

Here's the C#:

namespace BlazorDemo.Client
{
   public static class MyCSharpFunctions
   {
       public static void CsharpFunction()
       {
          // Notification.show();
       }
   }
}

Then the Javascript:

const CsharpFunction = Blazor.platform.findMethod(
"BlazorDemo.Client",
"BlazorDemo.Client",
"MyCSharpFunctions",
"CsharpFunction"
);
if (Javascriptcondition > 0) {
   Blazor.platform.callMethod(CsharpFunction, null)
}

For positive integers as arguments and where argument order doesn't matter:

1. Here's an unordered pairing function:

   <x, y> = x * y + trunc((|x - y| - 1)^2 / 4) = <y, x>
   

2. For x ? y, here's a unique unordered pairing function:

   <x, y> = if x < y:
              x * (y - 1) + trunc((y - x - 2)^2 / 4)
            if x > y:
              (x - 1) * y + trunc((x - y - 2)^2 / 4)
          = <y, x>
   

For reference purpose, for anyone searching how to change the path via code, I am quoting a useful post by a Delphi programmer from this web page: http://www.tek-tips.com/viewthread.cfm?qid=686382

TonHu (Programmer) 22 Oct 03 17:57 I found where I read the original posting, it's here: http://news.jrsoftware.org/news/innosetup.isx/msg02129....

The excerpt of what you would need is this:

You must specify the string "Environment" in LParam. In Delphi you'd do it this way:

 SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, Integer(PChar('Environment')));

It was suggested by Jordan Russell, http://www.jrsoftware.org, the author of (a.o.) InnoSetup, ("Inno Setup is a free installer for Windows programs. First introduced in 1997, Inno Setup today rivals and even surpasses many commercial installers in feature set and stability.") (I just would like more people to use InnoSetup )

Nothing an author can do can choose to open in a new tab instead of a new window; it is a user preference. (Note that the default user preference in most browsers is for new tabs, so a trivial test on a browser where that preference hasn't been changed will not demonstrate this.)

CSS3 proposed target-new, but the specification was abandoned.

The reverse is not true; by specifying certain window features for the window in the third argument of window.open(), you can trigger a new window when the preference is for tabs.

No need for css, you can just use the HR tag from HTML

<hr />

Use case match for early return purpose. It will force you to declare all return branches explicitly, preventing the careless mistake of forgetting to write return somewhere.

Was asked here before: Unix command to find lines common in two files

You could also try with perl (credit goes here)

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/'  file1 file2

Even icfantv's answer to this question is already perfect, I still have more findings in my test.

As a server socket in listening status, if it only in listening status, and even it accepts request and getting data from the client side, but without any data sending action. We still could restart the server at once after it's stopped. But if any data sending action happens in the server side to the client, the same service(same port) restart will have this error: (Address already in use).

I think this is caused by the TCP/IP design principles. When the server send the data back to client, it must ensure the data sending succeed, in order to do this, the OS(Linux) need monitor the connection even the server application closed this socket. But I still believe kernel socket designer could improve this issue.

Since FFT is symmetric over it's centre, half the values are just enough.

import numpy as np
import matplotlib.pyplot as plt

fs = 30.0
t = np.arange(0,10,1/fs)
x = np.cos(2*np.pi*10*t)

xF = np.fft.fft(x)
N = len(xF)
xF = xF[0:N/2]
fr = np.linspace(0,fs/2,N/2)

plt.ion()
plt.plot(fr,abs(xF)**2)

Perform rotation using transform: rotate(xdeg) and also apply overflow: hidden to the parent component to avoid overlapping effect

The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.

I think ADTC's solution is better, but mine's also works.

Here is the other solution I found

select p.name
from   person p
where  instr(p.name,chr(8211)) > 0; --contains the character chr(8211) 
                                    --at least 1 time

Center a div inside td using margin, the trick is to make the div width same as image width.

<td>
    <div style="margin: 0 auto; width: 130px">
          <img src="me.jpg" alt="me" style="width: 130px" />
    </div>
</td>

hash {}
hash[:a] = 'a'
hash[:b] = 'b'
hash = {:a => 'a' , :b = > b}

You might get your key and value from user input, so you can use Ruby .to_sym can convert a string to a symbol, and .to_i will convert a string to an integer.
For example:

movies ={}
movie = gets.chomp
rating = gets.chomp
movies[movie.to_sym] = rating.to_int
# movie will convert to a symbol as a key in our hash, and 
# rating will be an integer as a value.

Wrap each row of values to be inserted in brackets/parenthesis (value1, value2, value3) and separate the brackets/parenthesis by comma for as many as you wish to insert into the table.

INSERT INTO example
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

Common Resource Grep (crgrep) will search for string matches in tables/columns by name or content and supports a number of DBs, including SQLServer, Oracle and others. Full wild-carding and other useful options.

It's opensource (I'm the author).

You can look at the headers or libs installed. pkg-config can tell you where they are:

pkg-config --cflags opencv
pkg-config --libs opencv

Alternatively you can write a simple program and print the following defs:

CV_MAJOR_VERSION
CV_MINOR_VERSION

A similar question has been also asked here:

Not sure at what version this capability arrived, but you can use something like this to return all the properties of multiple child registry entries in an array:

$InstalledSoftware = Get-ChildItem "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | ForEach-Object {Get-ItemProperty "Registry::$_"}

Only adding this as Google brought me here for a relevant reason and I eventually came up with the above one-liner for dredging the registry.

Also you can do this with keypress event.

 private void textBox1_EnterKeyPress(object sender, KeyEventArgs e)

 {

  if (e.KeyCode == Keys.Enter)
   {
     // some code what you wanna do
   }


}

This will move foo.c to the new directory baz with the parent directory bar.

mv foo.c `mkdir -p ~/bar/baz/ && echo $_`

The -p option to mkdir will create intermediate directories as required.
Without -p all directories in the path prefix must already exist.

Everything inside backticks `` is executed and the output is returned in-line as part of your command.
Since mkdir doesn't return anything, only the output of echo $_ will be added to the command.

$_ references the last argument to the previously executed command.
In this case, it will return the path to your new directory (~/bar/baz/) passed to the mkdir command.

mv `ls -A | grep -v demo-app.zip` `mkdir -p demo-app && echo $_`

ls -A returns all file names including hidden files (except for the implicit . and ..).

The pipe symbol | is used to pipe the output of the ls command to grep (a command-line, plain-text search utility).
The -v flag directs grep to find and return all file names excluding demo-app.zip.
That list of files is added to our command-line as source arguments to the move command mv. The target argument is the path to the new directory passed to mkdir referenced using $_ and output using echo.

I suspect the problem is that you've put the "-D" after the -jar. Try this:

java -Dtest="true" -jar myApplication.jar

From the command line help:

java [-options] -jar jarfile [args...]

In other words, the way you've got it at the moment will treat -Dtest="true" as one of the arguments to pass to main instead of as a JVM argument.

(You should probably also drop the quotes, but it may well work anyway - it probably depends on your shell.)

You can use the slurp module to fetch a file from the remote host: (Thanks to @mlissner for suggesting it)

vars:
  amazon_linux_ami: "ami-fb8e9292"
  user_data_file: "base-ami-userdata.sh"
tasks:
- name: Load data
  slurp:
    src: "{{ user_data_file }}"
  register: slurped_user_data
- name: Decode data and store as fact # You can skip this if you want to use the right hand side directly...
  set_fact:
    user_data: "{{ slurped_user_data.content | b64decode }}"

implode(' ',$array);

I know it was asked over 6 years ago, but knowledge is still knowledge. This is different solution than all above, as I had to run it under SQL Server 2000:

DECLARE @TestData TABLE([ID] int, [SKU] char(6), [Product] varchar(15))
INSERT INTO @TestData values (1 ,'FOO-23', 'Orange')
INSERT INTO @TestData values (2 ,'BAR-23', 'Orange')
INSERT INTO @TestData values (3 ,'FOO-24', 'Apple')
INSERT INTO @TestData values (4 ,'FOO-25', 'Orange')

SELECT DISTINCT  [ID] = ( SELECT TOP 1 [ID]  FROM @TestData Y WHERE Y.[Product] = X.[Product])
                ,[SKU]= ( SELECT TOP 1 [SKU] FROM @TestData Y WHERE Y.[Product] = X.[Product])
                ,[PRODUCT] 
            FROM @TestData X  

I was able to overcome this issue with the following Visual Studio 2017 change:

1. In Team Explorer, go to Settings. Go to Global Settings to configure this option at the global level; go to Repository Settings to configure this option at the repo level.
2. Set Rebase local branch when pulling to the desired setting (for me it was True), and select Update to save.

See: https://docs.microsoft.com/en-us/vsts/git/concepts/git-config?view=vsts&tabs=visual-studio#rebase-local-branch-when-pulling

The answer, given by Alexandru is working quite nice. As he said, it is important that this "accessor"-view is added as the last element. Here is some code which did the trick for me:

        ...

        ...

            </LinearLayout>

        </LinearLayout>

    </FrameLayout>

</LinearLayout>

<!-- place a FrameLayout (match_parent) as the last child -->
<FrameLayout
    android:id="@+id/icon_frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

</TabHost>

in Java:

final MaterialDialog materialDialog = (MaterialDialog) dialogInterface;

FrameLayout frameLayout = (FrameLayout) materialDialog
        .findViewById(R.id.icon_frame_container);

frameLayout.setOnTouchListener(
        new OnSwipeTouchListener(ShowCardActivity.this) {

Profiling shows that statement: std::copy() is always as fast as memcpy() or faster is false.

Red Alert pointed out that the code uses memcpy from array to array and std::copy from array to vector. That coud be a reason for faster memcpy.

Since there is

v.reserve(sizeof(arr1));

there shall be no difference in copy to vector or array.

The code is fixed to use array for both cases. memcpy still faster:

{
    time_t t = time(NULL);
    for(uint32_t i = 0; i < iterations; ++i)
        memcpy(arr1, arr2, sizeof(arr1));

        std::copy(arr1, arr1 + sizeof(arr1), arr2);
    printf("std::copy() elapsed %ld s\n", time(NULL) - t);
}

memcpy()    elapsed 44 s
std::copy() elapsed 48 s 

The "logger.setLevel('ERROR');" is causing the problem. I do not understand why, but when I set it to anything other than "ALL", nothing gets printed in the file. I poked around a little bit and modified your code. It is working fine for me. I created two files.

logger.js

var log4js = require('log4js');
log4js.clearAppenders()
log4js.loadAppender('file');
log4js.addAppender(log4js.appenders.file('test.log'), 'test');
var logger = log4js.getLogger('test');
logger.setLevel('ERROR');

var getLogger = function() {
   return logger;
};

exports.logger = getLogger();

logger.test.js

var logger = require('./logger.js')

var log = logger.logger;

log.error("ERROR message");
log.trace("TRACE message");

When I run "node logger.test.js", I see only "ERROR message" in test.log file. If I change the level to "TRACE" then both lines are printed on test.log.

In SQLite the best you can do is use the integers 0 and 1 to represent false and true. You could declare the column type like this:

CREATE TABLE foo(mycolumn BOOLEAN NOT NULL CHECK (mycolumn IN (0,1)));

Omit the NOT NULL if you want to allow NULL in addition to 0 and 1.

The use of the type name BOOLEAN here is for readability, to SQLite it's just a type with NUMERIC affinity.

Note that CHECK constraints have been supported since SQLite 3.3.0 (2006).

Here are some example INSERTs that will work: (note how strings and floating point numbers are parsed as integers)

sqlite> INSERT INTO foo VALUES(0);
sqlite> INSERT INTO foo VALUES(1);
sqlite> INSERT INTO foo VALUES(0.0);
sqlite> INSERT INTO foo VALUES(1.0);
sqlite> INSERT INTO foo VALUES("0.0");
sqlite> INSERT INTO foo VALUES("1.0");
sqlite> select mycolumn, typeof(mycolumn) from foo;
0|integer
1|integer
0|integer
1|integer
0|integer
1|integer

and some that will fail:

sqlite> INSERT INTO foo VALUES("-1");
Error: constraint failed
sqlite> INSERT INTO foo VALUES(0.24);
Error: constraint failed
sqlite> INSERT INTO foo VALUES(100);
Error: constraint failed
sqlite> INSERT INTO foo VALUES(NULL);
Error: foo.mycolumn may not be NULL
sqlite> INSERT INTO foo VALUES("true");
Error: constraint failed
sqlite> INSERT INTO foo VALUES("false");
Error: constraint failed

You can go with option 3 if you modify your abstract base class to require the property value in the constructor, you won't miss any paths. I'd really consider this option.

abstract class Aunt
{
    protected int MyInt;
    protected Aunt(int myInt)
    {
        MyInt = myInt;
    }

}

Of course, you then still have the option of making the field private and then, depending on the need, exposing a protected or public property getter.

ADD go /usr/local/

will copy the contents of your local go directory in the /usr/local/ directory of your docker image.

To copy the go directory itself in /usr/local/ use:

ADD go /usr/local/go

or

COPY go /usr/local/go

You can do either…

$qb->where('e.fecha BETWEEN :monday AND :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

or…

$qb->where('e.fecha > :monday')
   ->andWhere('e.fecha < :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

The server.contextPath or server.context-path works if

in pom.xml

1. packing should be war not jar

2. Add following dependencies

   <dependency>
       <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <!-- Tomcat/TC server -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>
   

   In eclipse, right click on project --> Run as --> Spring Boot App.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Most IIS sections are locked by default but you can "unlock" them by setting the attribute overrideModeDefault from "Deny" to "Allow" for the relevant section group by modifying the ApplicationHost.config file located in %windir%\system32\inetsrv\config in Administrator mode

I'm guessing the question you really care about here is:

Is there a way to force Python to release all the memory that was used (if you know you won't be using that much memory again)?

No, there is not. But there is an easy workaround: child processes.

If you need 500MB of temporary storage for 5 minutes, but after that you need to run for another 2 hours and won't touch that much memory ever again, spawn a child process to do the memory-intensive work. When the child process goes away, the memory gets released.

This isn't completely trivial and free, but it's pretty easy and cheap, which is usually good enough for the trade to be worthwhile.

First, the easiest way to create a child process is with concurrent.futures (or, for 3.1 and earlier, the futures backport on PyPI):

with concurrent.futures.ProcessPoolExecutor(max_workers=1) as executor:
    result = executor.submit(func, *args, **kwargs).result()

If you need a little more control, use the multiprocessing module.

The costs are:

• Process startup is kind of slow on some platforms, notably Windows. We're talking milliseconds here, not minutes, and if you're spinning up one child to do 300 seconds' worth of work, you won't even notice it. But it's not free.
• If the large amount of temporary memory you use really is large, doing this can cause your main program to get swapped out. Of course you're saving time in the long run, because that if that memory hung around forever it would have to lead to swapping at some point. But this can turn gradual slowness into very noticeable all-at-once (and early) delays in some use cases.
• Sending large amounts of data between processes can be slow. Again, if you're talking about sending over 2K of arguments and getting back 64K of results, you won't even notice it, but if you're sending and receiving large amounts of data, you'll want to use some other mechanism (a file, mmapped or otherwise; the shared-memory APIs in multiprocessing; etc.).
• Sending large amounts of data between processes means the data have to be pickleable (or, if you stick them in a file or shared memory, struct-able or ideally ctypes-able).

Use regex pattern ^(?=.{8})(?=.*[^a-zA-Z])

Explanation:

^(?=.{8})(?=.*[^a-zA-Z])
¦+------++-------------+
¦   ¦           ¦
¦   ¦           + string contains some non-letter character
¦   ¦
¦   + string contains at least 8 characters
¦
+ begining of line/string

If you want to limit also maximum length (let's say 16), then use regex pattern:

^(?=.{8,16}$)(?=.*[^a-zA-Z])

3 steps:

1. Check the sorce code (HTML) of YouTube, you'll get the link like this (http%253A%252F%252Fo-o.preferred.telemar-cnf1.v18.lscache6.c.youtube.com%252Fvideoplayback ...);

2. Decode the url (remove the codes %2B,%25 etc), create a decoder with the codes: http://www.w3schools.com/tags/ref_urlencode.asp and use the function Uri.decode(url) to replace invalid escaped octets;

3. Use the code to download stream:

   URL u = null;
   InputStream is = null;  
   
   try {
       u = new URL(url);
       is = u.openStream(); 
       HttpURLConnection huc = (HttpURLConnection)u.openConnection(); //to know the size of video
       int size = huc.getContentLength();                 
   
       if(huc != null) {
           String fileName = "FILE.mp4";
           String storagePath = Environment.getExternalStorageDirectory().toString();
           File f = new File(storagePath,fileName);
   
           FileOutputStream fos = new FileOutputStream(f);
           byte[] buffer = new byte[1024];
           int len1 = 0;
           if(is != null) {
               while ((len1 = is.read(buffer)) > 0) {
                   fos.write(buffer,0, len1);  
               }
           }
           if(fos != null) {
               fos.close();
           }
       }                       
   } catch (MalformedURLException mue) {
       mue.printStackTrace();
   } catch (IOException ioe) {
       ioe.printStackTrace();
   } finally {
       try {               
           if(is != null) {
               is.close();
           }
       } catch (IOException ioe) {
           // just going to ignore this one
       }
   }
   

That's all, most of stuff you'll find on the web!!!

I use the following code to write raw text to files, to update my CPU-settings. Hope this helps out! Script:

#!/bin/sh

cat > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor <<EOF
performance
EOF

cat > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor <<EOF
performance
EOF

This writes the text "performance" to the two files mentioned in the script above. This example overwrite old data in files.

This code is saved as a file (cpu_update.sh) and to make it executable run:

chmod +x cpu_update.sh

After that, you can run the script with:

./cpu_update.sh

IF you do not want to overwrite the old data in the file, switch out

cat > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor <<EOF

with

cat >> /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor <<EOF

This will append your text to the end of the file without removing what other data already is in the file.

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

The only thin you have to change is to use property "params" rather than "data" when you create your $http object:

$http({
   method: 'POST',
   url: serviceUrl + '/ClientUpdate',
   params: { LangUserId: userId, clientJSON: clients[i] },
})

In the example above clients[i] is just JSON object (not serialized in any way). If you use "params" rather than "data" angular will serialize the object for you using $httpParamSerializer: https://docs.angularjs.org/api/ng/service/$httpParamSerializer

.csv or POI will certainly do it, but you should be aware of Andy Khan's JExcel. I think it's by far the best Java library for working with Excel there is.

A more naive version, at least you're sure that it'll work on all devices, without conversion and ES6 :

const children = parent.children;
for (var i = 0; i < children.length; i++){
    console.log(children[i]);
}

https://jsfiddle.net/swb12kqn/5/

Try this:

<!-- first page -->
<?php
  session_start(); 
  session_register('myvar');
  $_SESSION['myvar'] == 'myvalue';
?>

<!-- second page -->
<?php
    session_start();
    echo("1");
    if(session_is_registered('myvar'))
    {
        echo("2");
       if($_SESSION['myvar'] == 'myvalue')
       {
           echo("3");
           exit;
       }
    }
    ?>

Actually, you need to call SET SERVEROUTPUT ON; before the BEGIN call.

Everyone suggested this but offers no advice where to actually place the line:

SET SERVEROUTPUT ON;

BEGIN
    FOR rec in (SELECT * FROM EMPLOYEES) LOOP
        DBMS_OUTPUT.PUT_LINE(rec.EmployeeName);
    ENDLOOP;
END;

Otherwise, you won't see any output.

Or maybe even easier

grep -R put **/*bills*

The ** glob syntax means "any depth of directories". It will work in Zsh, and I think recent versions of Bash too.

For sentOs, it's works for me At first stop service by sudo service jenkins stop

Than remove by sudo yum remove jenkins

The most important thing you can do is to make sure that the people you are sending email to are not likely going to hit the "Spam" button when they receive your email. So, stick to the following rules of thumb:

• Make sure you have permission from the people you are sending email to. Don't ever send email to someone who did not request it from you.

• Clearly identify who you are right at the top of each message, and why the person is receiving the email.

• At least once a month, send out a reminder email to people on your list (if you are running a list), forcing them to opt back in to the list in order to keep receiving communications from you. Yes, this will mean your list gets shorter over time, but the up-side is that the people on your list are "bought in" and will be less likely to flag your email.

• Keep your content highly relevant and useful.

• Give people an easy way to opt out of further communications.

• Use an email sending service like SendGrid that works hard to maintain a good IP reputation.

• Avoid using short links - these are often blacklisted.

Following these rules of thumb will go a long way.

I guess there is a simple solution which I recently used after going through so many answers here.

with open(file_name) as f_in:   
    for line in f_in:
        if len(line.split()) == 0:
            continue

This just does the same work, ignoring all empty line.

I use a jQuery plugin called ColorBox, it is

1. Very easy to use
2. lightweight
3. customizable
4. the nicest popup dialog I have seen for jQuery yet

Sets are faster, morover you get more functions with sets, such as lets say you have two sets :

set1 = {"Harry Potter", "James Bond", "Iron Man"}
set2 = {"Captain America", "Black Widow", "Hulk", "Harry Potter", "James Bond"}

We can easily join two sets:

set3 = set1.union(set2)

Find out what is common in both:

set3 = set1.intersection(set2)

Find out what is different in both:

set3 = set1.difference(set2)

And much more! Just try them out, they are fun! Moreover if you have to work on the different values within 2 list or common values within 2 lists, I prefer to convert your lists to sets, and many programmers do in that way. Hope it helps you :-)

Use the .IndexOf() method of the list. Specs for the method can be found on MSDN.

EncodeAndSend is not a static function, which means it can be called on an instance of the class CPMSifDlg. You cannot write this:

 CPMSifDlg::EncodeAndSend(/*...*/);  //wrong - EncodeAndSend is not static

It should rather be called as:

 CPMSifDlg dlg; //create instance, assuming it has default constructor!
 dlg.EncodeAndSend(/*...*/);   //correct 

In the most languages, break does only cancel loops like for, while etc.

cat input.csv | sed 's/\r/\n/g' > output.csv

worked for me

You could test the url via AJAX and read the status code - that is if the URL is in the same domain.

If it's a remote domain, you could have a server script on your own domain check out a remote URL.

It's actually not PHP, it's apache using mod_rewrite. What happens is the person requests the link, www.example.com/profile/12345 and then apache chops it up using a rewrite rule making it look like this, www.example.com/profile.php?u=12345, to the server. You can find more here: Rewrite Guide

Yes not working! I spent whole day with this stupid phpMyAdmin. Just add a new user with a password

1 - Login to mysql or mariadb mysql -u root -p

2 - Run these SQL commands to create a new user with all permissions (or grant your custom permissions)

CREATE USER 'someone'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'someone'@'localhost';
FLUSH PRIVILEGES;

2 - Go to /etc/phpMyAdmin/config.inc.php and change this:

$cfg['Servers'][$i]['user']          = 'someone';
$cfg['Servers'][$i]['password']      = 'password';

WARNING: This config is for localhost development server only, If you're running a production server you must use strong credentials and not setting user pass in config.inc.php

The replace one liner is great but only works because XX and bar have the same lentgh

A good and general def would be:

def findN(s,sub,N,replaceString="XXX"):
    return s.replace(sub,replaceString,N-1).find(sub) - (len(replaceString)-len(sub))*(N-1)

var=$((count7 + count1))

Arithmetic in bash uses $((...)) syntax.

You do not need to $ symbol within the $(( ))

In my case I need to do

sudo npm install  

my project is inside /var/www so I also need to set proper permissions.

You put the declaration in a header file, e.g.

 extern int my_global;

In one of your .c files you define it at global scope.

int my_global;

Every .c file that wants access to my_global includes the header file with the extern in.

Here is one way to do it:

>>> n = 46
>>> (n + 9) // 10 * 10
50

views.py

from django.contrib import messages 

def view_name(request):
    if request.method == 'POST':
        form = form_class(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks'/)
        else:
            messages.error(request, "Error")
return render(request, 'page.html', {'form':form_class()})

If you want to show the errors of the form other than that not valid just put {{form.as_p}} like what I did below

page.html

<html>
    <head>
        <script>
            {% if messages %}
                {% for message in messages %}
                    alert('{{message}}')
                {% endfor %}
            {% endif %}
        </script>
    </head>
    <body>
        {{form.as_p}}
    </body>
</html> 

One Idea:

UPDATE tbl_ClientNotes
SET ordering=ISNULL(@ordering, ordering), 
    title=ISNULL(@title, title),  
    content=ISNULL(@content, content)
WHERE id=@id

You could try xmllint

The xmllint program parses one or more XML files, specified on the command line as xmlfile. It prints various types of output, depending upon the options selected. It is useful for detecting errors both in XML code and in the XML parser itse

It allows you select elements in the XML doc by xpath, using the --pattern option.

On Mac OS X (Yosemite), it is installed by default.
On Ubuntu, if it is not already installed, you can run apt-get install libxml2-utils

Instead of handcranking your models try using something like the Json2csharp.com website. Paste In an example JSON response, the fuller the better and then pull in the resultant generated classes. This, at least, takes away some moving parts, will get you the shape of the JSON in csharp giving the serialiser an easier time and you shouldnt have to add attributes.

Just get it working and then make amendments to your class names, to conform to your naming conventions, and add in attributes later.

EDIT: Ok after a little messing around I have successfully deserialised the result into a List of Job (I used Json2csharp.com to create the class for me)

public class Job
{
        public string id { get; set; }
        public string position_title { get; set; }
        public string organization_name { get; set; }
        public string rate_interval_code { get; set; }
        public int minimum { get; set; }
        public int maximum { get; set; }
        public string start_date { get; set; }
        public string end_date { get; set; }
        public List<string> locations { get; set; }
        public string url { get; set; }
}

And an edit to your code:

        List<Job> model = null;
        var client = new HttpClient();
        var task = client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs")
          .ContinueWith((taskwithresponse) =>
          {
              var response = taskwithresponse.Result;
              var jsonString = response.Content.ReadAsStringAsync();
              jsonString.Wait();
              model = JsonConvert.DeserializeObject<List<Job>>(jsonString.Result);

          });
        task.Wait();

This means you can get rid of your containing object. Its worth noting that this isn't a Task related issue but rather a deserialisation issue.

EDIT 2:

There is a way to take a JSON object and generate classes in Visual Studio. Simply copy the JSON of choice and then Edit> Paste Special > Paste JSON as Classes. A whole page is devoted to this here:

http://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special-JSON-And-Xml/

 date('Y-m-d',(strtotime ( '-1 day' , strtotime ( $date) ) ));

The default behaviour of Newtonsoft.Json is going to find the public constructors. If your default constructor is only used in containing class or the same assembly, you can reduce the access level to protected or internal so that Newtonsoft.Json will pick your desired public constructor.

Admittedly, this solution is rather very limited to specific cases.

internal Result() { }

public Result(int? code, string format, Dictionary<string, string> details = null)
{
    Code = code ?? ERROR_CODE;
    Format = format;

    if (details == null)
        Details = new Dictionary<string, string>();
    else
        Details = details;
}

Source: CodePath - UI Testing With Espresso

6. Finally, we need to pull in the Espresso dependencies and set the test runner in our app build.gradle:

// build.gradle
...
android {
    ...
    defaultConfig {
        ...
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
}

dependencies {
    ...
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
        // Necessary if your app targets Marshmallow (since Espresso
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test:runner:0.5') {
        // Necessary if your app targets Marshmallow (since the test runner
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
}

I've added that to my gradle file and the warning disappeared.

Also, if you get any other dependency listed as conflicting, such as support-annotations, try excluding it too from the androidTestCompile dependencies.

I decide to publish my example that I used in my case. I tried to replace content in div using a script. My problem was that Chrome did not recognized / did not run that script.

In more detail What I wanted to do: To click on a link, and that link to "read" an external html file, that it will be loaded in a div section.

• I found out that by placing the script before the DIV with ID that was called, the script did not work.
• If the script was in another DIV, also it does not work

• The script must be coded using document.addEventListener('DOMContentLoaded', function() as it was told

      <body>
      <a id=id_page href ="#loving"   onclick="load_services()"> loving   </a>
  
          <script>
                  // This script MUST BE under the "ID" that is calling
                  // Do not transfer it to a differ DIV than the caller "ID"
                  document.getElementById("id_page").addEventListener("click", function(){
                  document.getElementById("mainbody").innerHTML = '<object data="Services.html" class="loving_css_edit"; ></object>'; });
              </script>
      </body>
  
    <div id="mainbody" class="main_body">
          "here is loaded the external html file when the loving link will 
           be  clicked. "
    </div>
  

The following steps solved blank white screen problem on my Laravel 5.

• Go to your Laravel root folder
• Give write permission to bootstrap/cache and storage directories

sudo chmod -R 777 bootstrap/cache storage

• Rename .env.example to .env
• Generate application key with the following command in terminal/command-prompt from Laravel root:

php artisan key:generate

This will generate the encryption key and update the value of APP_KEY in .env file

This should solve the problem.

If the problem still exists, then update config/app.php with the new key generated from the above artisan key generate command:

'key' => env('APP_KEY', 'SomeRandomString'),

to

'key' => env('APP_KEY', 'KEY_GENERATED_FROM_ABOVE_COMMAND'),

Why don't these questions get answered with the obvious answer?

a = numpy.empty(n, dtype=object)

This creates an array of length n that can store objects. It can't be resized or appended to. In particular, it doesn't waste space by padding its length. This is the Python equivalent of Java's

Object[] a = new Object[n];

If you're really interested in performance and space and know that your array will only store certain numeric types then you can change the dtype argument to some other value like int. Then numpy will pack these elements directly into the array rather than making the array reference int objects.

box-sizing: border-box;
width: 100%;
padding: 5px;

box-sizing: border box; makes it so that padding, margin and border are included in the width calculations.

MDN

Use eval() instead of ast.literal_eval() if the input is trusted (which it is in your case).

raw_data = userfile.read().split('\n')
for a in raw_data : 
    print a
    btc_history.append(eval(a))

This works for me in Python 3.6.0

For anyone working with React and looking for solution. I’ve found out that easiest way is to use onWheelCapture prop in Input component like this:

onWheelCapture={e => { e.target.blur() }}

This is way too vague to give you an answer relevant to your specific case. It depends on a lot of things. Jeff Atwood (founder of this site) actually wrote about this. For the most part, though, if you have the right indexes and you properly do your JOINs it is usually going to be faster to do 1 trip than several.

I have found another reason: different versions used for icons in toolbox and references in the project. After inserting the objects in some form, the error started.

Please try CURRENT_TIME() or now() functions

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', NOW(), '$comments')"

OR

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', CURRENT_TIME(), '$comments')"

OR you could try with PHP date function here:

$date = date("Y-m-d H:i:s");

Try this way:

dataGridView.CurrentCell.Value = newValue;

dataGridView.EndEdit();

dataGridView.CurrentCell.Value = newValue;

dataGridView.EndEdit();

Need to write two times...

The problem here is that the rendering of a RadioButtonList wraps the individual radio buttons (ListItems) in span tags and even when you assign a client-side event handler to the list item directly using Attributes it assigns the event to the span. Assigning the event to the RadioButtonList assigns it to the table it renders in.

The trick here is to add the ListItems on the aspx page and not from the code behind. You can then assign the JavaScript function to the onClick property. This blog post; attaching client-side event handler to radio button list by Juri Strumpflohner explains it all.

This only works if you know the ListItems in advance and does not help where the items in the RadioButtonList need to be dynamically added using the code behind.

The solution i found was

const [files, setFiles] = useState([] as any);

First, let me fix a little bit your declaration:

List<Map<String, List<String>>> listOfMapOfList = 
    new HashList<Map<String, List<String>>>();

Please pay attention that I used concrete class (HashMap) only once. It is important to use interface where you can to be able to change the implementation later.

Now you want to add element to the list, don't you? But the element is a map, so you have to create it:

Map<String, List<String>> mapOfList = new HashMap<String, List<String>>();

Now you want to populate the map. Fortunately you can use utility that creates lists for you, otherwise you have to create list separately:

mapOfList.put("mykey", Arrays.asList("one", "two", "three"));

OK, now we are ready to add the map into the list:

listOfMapOfList.add(mapOfList);

BUT:

Stop creating complicated collections right now! Think about the future: you will probably have to change the internal map to something else or list to set etc. This will probably cause you to re-write significant parts of your code. Instead define class that contains you data and then add it to one-dimentional collection:

Let's call your class Student (just as example):

public Student {
    private String firstName;
    private String lastName;
    private int studentId;

    private Colectiuon<String> courseworks = Collections.emtpyList();

    //constructors, getters, setters etc
}

Now you can define simple collection:

Collection<Student> students = new ArrayList<Student>();

If in future you want to put your students into map where key is the studentId, do it:

Map<Integer, Student> students = new HashMap<Integer, Student>();

1. Same as Tim and Farhan wrote: Fork your own copy of the project:
2. After a few seconds, you'll be redirected to your own forked copy of the project:
3. Navigate to the file(s) you need to change and click "Edit this file" in the toolbar:
4. After editing, write a few words describing the changes and then "Commit changes", just as well to the master branch (since this is only your own copy and not the "main" project).
5. Repeat steps 3 and 4 for all files you need to edit, and then go back to the root of your copy of the project. There, click the green "Compare, review..." button:

A self-explanatory simple one-liner to extract token for kubernetes dashboard login.

kubectl describe secret -n kube-system | grep deployment -A 12

Copy the token and paste it on the kubernetes dashboard under token sign in option and you are good to use kubernetes dashboard

1. Java 8 Streams

public static String capitalizeAll(String str) {
    if (str == null || str.isEmpty()) {
        return str;
    }

    return Arrays.stream(str.split("\\s+"))
            .map(t -> t.substring(0, 1).toUpperCase() + t.substring(1))
            .collect(Collectors.joining(" "));
}

Examples:

System.out.println(capitalizeAll("jon skeet")); // Jon Skeet
System.out.println(capitalizeAll("miles o'Brien")); // Miles O'Brien
System.out.println(capitalizeAll("old mcdonald")); // Old Mcdonald
System.out.println(capitalizeAll(null)); // null

For foo bAR to Foo Bar, replace the map() method with the following:

.map(t -> t.substring(0, 1).toUpperCase() + t.substring(1).toLowerCase())

2. String.replaceAll() (Java 9+)

ublic static String capitalizeAll(String str) {
    if (str == null || str.isEmpty()) {
        return str;
    }

    return Pattern.compile("\\b(.)(.*?)\\b")
            .matcher(str)
            .replaceAll(match -> match.group(1).toUpperCase() + match.group(2));
}

Examples:

System.out.println(capitalizeAll("12 ways to learn java")); // 12 Ways To Learn Java
System.out.println(capitalizeAll("i am atta")); // I Am Atta
System.out.println(capitalizeAll(null)); // null

3. Apache Commons Text

System.out.println(WordUtils.capitalize("love is everywhere")); // Love Is Everywhere
System.out.println(WordUtils.capitalize("sky, sky, blue sky!")); // Sky, Sky, Blue Sky!
System.out.println(WordUtils.capitalize(null)); // null

For titlecase:

System.out.println(WordUtils.capitalizeFully("fOO bAR")); // Foo Bar
System.out.println(WordUtils.capitalizeFully("sKy is BLUE!")); // Sky Is Blue!

globbing **

Using grep -r works, but it may overkill, especially in large folders.

For more practical usage, here is the syntax which uses globbing syntax (**):

grep "texthere" **/*.txt

which greps only specific files with pattern selected pattern. It works for supported shells such as Bash +4 or zsh.

To activate this feature, run: shopt -s globstar.

See also: How do I find all files containing specific text on Linux?

git grep

For projects under Git version control, use:

git grep "pattern"

which is much quicker.

ripgrep

For larger projects, the quickest grepping tool is ripgrep which greps files recursively by default:

rg "pattern" .

It's built on top of Rust's regex engine which uses finite automata, SIMD and aggressive literal optimizations to make searching very fast. Check the detailed analysis here.

the equivalent to the batch program would be

#include<iostream>
int main()
{
    std::cout<<"Hello, World!\n";
    std::cin.get();
    return 0;
}

The additional line does exactly what PAUSE does, waits for a single character input

Use (LocalDB)\MSSQLLocalDB as the server name

I don't know if you managed to resolve this but I have recently experienced a similar problem where the For loop left one view each time. I found this was because the self.subviews was mutated (maybe) when the removeFromSuperview() was called.

To fix this I did:

let subViews: Array = self.subviews.copy()
for (var subview: NSView!) in subViews
{
    subview.removeFromSuperview()
}

By doing .copy(), I could perform the removal of each subview while mutating the self.subviews array. This is because the copied array (subViews) contains all of the references to the objects and is not mutated.

EDIT: In your case I think you would use:

let theSubviews: Array = container_view.subviews.copy()
for (var view: NSView!) in theSubviews
{
    view.removeFromSuperview()
}

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. (...)

The colClasses vector must have length equal to the number of imported columns. Supposing the rest of your dataset columns are 5:

colClasses=c("character",rep("numeric",5))

I found another server side solution for web dev using PHP to get the size of an iframe.

First is using server script PHP to an external call via internal function: (like a file_get_contents with but curl and dom).

function curl_get_file_contents($url,$proxyActivation=false) {
    global $proxy;
    $c = curl_init();
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
    curl_setopt($c, CURLOPT_REFERER, $url);
    curl_setopt($c, CURLOPT_URL, $url);
    curl_setopt($c, CURLOPT_FOLLOWLOCATION, 1);
    if($proxyActivation) {
        curl_setopt($c, CURLOPT_PROXY, $proxy);
    }
    $contents = curl_exec($c);
    curl_close($c);
    $dom = new DOMDocument();
    $dom->preserveWhiteSpace = false;
    @$dom->loadHTML($contents);
    $form = $dom->getElementsByTagName("body")->item(0);
    if ($contents) //si on a du contenu
        return $dom->saveHTML();
    else
        return FALSE;
}
$url = "http://www.google.com"; //Exernal url test to iframe
<html>
    <head>
    <script type="text/javascript">

    </script>
    <style type="text/css">
    #iframe_reserve {
        width: 560px;
        height: 228px
    }
    </style>
    </head>

    <body>
        <div id="iframe_reserve"><?php echo curl_get_file_contents($url); ?></div>

        <iframe id="myiframe" src="http://www.google.com" scrolling="no" marginwidth="0" marginheight="0" frameborder="0"  style="overflow:none; width:100%; display:none"></iframe>

        <script type="text/javascript">
            window.onload = function(){
            document.getElementById("iframe_reserve").style.display = "block";
            var divHeight = document.getElementById("iframe_reserve").clientHeight;
            document.getElementById("iframe_reserve").style.display = "none";
            document.getElementById("myiframe").style.display = "block";
            document.getElementById("myiframe").style.height = divHeight;
            alert(divHeight);
            };
        </script>
    </body>
</html>

You need to display under the div (iframe_reserve) the html generated by the function call by using a simple echo curl_get_file_contents("location url iframe","activation proxy")

After doing this a body event function onload with javascript take height of the page iframe just with a simple control of the content div (iframe_reserve)

So I used divHeight = document.getElementById("iframe_reserve").clientHeight; to get height of the page external we are going to call after masked the div container (iframe_reserve). After this we load the iframe with its good height that's all.

As per this example:

import numpy as np
import matplotlib.pyplot as plt

N = 50
x = np.random.rand(N)
y = np.random.rand(N)

plt.scatter(x, y)
plt.show()

will produce:

To unpack your data from pairs into lists use zip:

x, y = zip(*li)

So, the one-liner:

plt.scatter(*zip(*li))

Your response should be something like this to be qualified as Json Array.

{
  "songs":[
    {"2562862600": {"id":"2562862600", "pos":1}},  
    {"2562862620": {"id":"2562862620", "pos":1}},  
    {"2562862604": {"id":"2562862604", "pos":1}},  
    {"2573433638": {"id":"2573433638", "pos":1}}
  ]
}

You can parse your response as follows

String resp = ...//String output from your source
JSONObject ob = new JSONObject(resp);  
JSONArray arr = ob.getJSONArray("songs");

for(int i=0; i<arr.length(); i++){   
  JSONObject o = arr.getJSONObject(i);  
  System.out.println(o);  
}

On ubuntu

 sudo apt-get install librxtx-java then 

add RXTX jars to the project which are in

 usr/share/java

Check if .babelrc is inside your application root folder, not inside a subfolder. if that's the case move file to root.

The strpos() finds the offset of the underscore, then substr grabs everything from that index plus 1, onwards.

$data = "123_String";    
$whatIWant = substr($data, strpos($data, "_") + 1);    
echo $whatIWant;

If you also want to check if the underscore character (_) exists in your string before trying to get it, you can use the following:

if (($pos = strpos($data, "_")) !== FALSE) { 
    $whatIWant = substr($data, $pos+1); 
}

You need to remove the scanner closing lines: scan.close();

It happened to me before and that was the reason.

Wrapping can be done in various ways. I'll mention 2 of them:

1.) text wrapping - using white-space property http://www.w3schools.com/cssref/pr_text_white-space.asp

2.) word wrapping - using word-wrap property http://webdesignerwall.com/tutorials/word-wrap-force-text-to-wrap

By the way, in order to work using these 2 approaches, I believe you need to set the "display" property to block of the corresponding span element.

However, as Kirill already mentioned, it's a good idea to think about it for a moment. You're talking about forcing the text into a paragraph. PARAGRAPH. That should ring some bells in your head, shouldn't it? ;)

Use the -k option (or --key=POS1[,POS2]). It can appear multiple times and each key can have global options (such as n for numeric sort)

To view database roles assigned to users, you can use sys.database_role_members

The following query returns the members of the database roles.

SELECT DP1.name AS DatabaseRoleName,   
    isnull (DP2.name, 'No members') AS DatabaseUserName   
FROM sys.database_role_members AS DRM  
RIGHT OUTER JOIN sys.database_principals AS DP1  
    ON DRM.role_principal_id = DP1.principal_id  
LEFT OUTER JOIN sys.database_principals AS DP2  
    ON DRM.member_principal_id = DP2.principal_id  
WHERE DP1.type = 'R'
ORDER BY DP1.name;  

Just (array) is missing in your code before the simplexml object:

...

$xml   = simplexml_load_string($string, 'SimpleXMLElement', LIBXML_NOCDATA);

$array = json_decode(json_encode((array)$xml), TRUE);
                                 ^^^^^^^
...

Doesn't allow duplicates in the sense, It allow to add you but it does'nt care about this key already have a value or not. So at present for one key there will be only one value

It silently overrides the value for null key. No exception.

When you try to get, the last inserted value with null will be return.

That is not only with null and for any key.

Have a quick example

   Map m = new HashMap<String, String>();
   m.put("1", "a");
   m.put("1", "b");  //no exception
   System.out.println(m.get("1")); //b

You are missing a semicolon at the end of your 'struct' definition.

Also,

A problem that you get when you allow constructors in interfaces comes from the possibility to implement several interfaces at the same time. When a class implements several interfaces that define different constructors, the class would have to implement several constructors, each one satisfying only one interface, but not the others. It will be impossible to construct an object that calls each of these constructors.

Or in code:

interface Named { Named(String name); }
interface HasList { HasList(List list); }

class A implements Named, HasList {

  /** implements Named constructor.
   * This constructor should not be used from outside, 
   * because List parameter is missing
   */
  public A(String name)  { 
    ...
  }

  /** implements HasList constructor.
   * This constructor should not be used from outside, 
   * because String parameter is missing
   */
  public A(List list) {
    ...
  }

  /** This is the constructor that we would actually 
   * need to satisfy both interfaces at the same time
   */ 
  public A(String name, List list) {
    this(name);
    // the next line is illegal; you can only call one other super constructor
    this(list); 
  }
}

In jupyter notebook run:

!echo y | jupyter kernelspec uninstall unwanted-kernel 

In anaconda prompt run:

jupyter kernelspec uninstall unwanted-kernel

Example (junit version- 4.13)

import static org.assertj.core.api.Assertions.assertThat;
import org.junit.Test;

public class TestStr {

    String testStr = "hi,i am a test string";
    assertThat(testStr).contains("test");
 }

}

Your server is imposing some resource limit that your site is hitting. This is usually RAM, CPU, or INODES.

Ask your server administrator what the limits are and what it is you are hitting to solve.

If you use Node.JS, You can use the native Buffer module by doing :

const token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWUsImp0aSI6ImU3YjQ0Mjc4LTZlZDYtNDJlZC05MTZmLWFjZDQzNzhkM2U0YSIsImlhdCI6MTU5NTg3NzUxOCwiZXhwIjoxNTk1ODgxMTE4fQ.WXyDlDMMSJAjOFF9oAU9JrRHg2wio-WolWAkAaY3kg4';
const base64Url = token.split('.')[1];
const decoded = Buffer.from(base64Url, 'base64').toString();
console.log(decoded)

And you're good to go :-)

From a 'SQL the language' perspective the two constructs are equivalent and which one you choose is one of those 'lifestyle' choices we all have to make. I think there is a good case for DISTINCT being more explicit (and therefore is more considerate to the person who will inherit your code etc) but that doesn't mean the GROUP BY construct is an invalid choice.

I think this 'GROUP BY is for aggregates' is the wrong emphasis. Folk should be aware that the set function (MAX, MIN, COUNT, etc) can be omitted so that they can understand the coder's intent when it is.

The ideal optimizer will recognize equivalent SQL constructs and will always pick the ideal plan accordingly. For your real life SQL engine of choice, you must test :)

PS note the position of the DISTINCT keyword in the select clause may produce different results e.g. contrast:

SELECT COUNT(DISTINCT C) FROM myTbl;

SELECT DISTINCT COUNT(C) FROM myTbl;

For Ubuntu 20 it did help me to use my systems chromium driver instead of the downloaded one:

# chromium which
/snap/bin/chromium

driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
                          options=chrome_options)

And for the downloaded webdriver looks like it needs the remote debug port --remote-debugging-port=9222 to be set, as in one of the answers (by Soheil Pourbafrani):

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)

For Windows users:

To add onto @CoderSpeed's answer above (CoderSpeed's answer). Create a batch file (.bat) with the commands you would usually enter on the CLI, e.g.:

cd "C:\Program Files\MongoDB\Server\4.0\bin" mongod.exe

Windows Script Host’s Run Method allows you run a program or script in invisible mode. Here is a sample Windows script code that launches a batch file named syncfiles.bat invisibly.

Let’s say we have a file named syncfiles.bat in C:\Batch Files directory. Let’s launch it in hidden mode using Windows Scripting.

Copy the following lines to Notepad.

Set WshShell = CreateObject("WScript.Shell") WshShell.Run chr(34) & "C:\Batch Files\syncfiles.bat" & Chr(34), 0 Set WshShell = Nothing

Note: Replace the batch file name/path accordingly in the script according to your requirement. Save the file with .VBS extension, say launch_bat.vbs Edit the .BAT file name and path accordingly, and save the file. Double-click to run the launch_bat.vbs file, which in-turn launches the batch file syncfiles.bat invisibly.
