Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Quite a few applications seem to implement Steganography on JPEG, so it's feasible:

http://www.jjtc.com/Steganography/toolmatrix.htm

Here's an article regarding a relevant algorithm (PM1) to get you started:

http://link.springer.com/article/10.1007%2Fs00500-008-0327-7#page-1

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

This worked for me

Deactivate AdBlock.

Go to inspect -> settings gear -> Uncheck 'enable javascript source maps' and 'enable css source map'.

Refresh.

You Can Wrap your widget with Flexible Widget and than you can set property of Text using overflow property of Text Widget. you have to set TextOverflow.clip for example:-

Flexible
(child: new Text("This is Dummy Long Text",
 style: TextStyle(
 fontFamily: "Roboto",
 color: Colors.black,
 fontSize: 10.0,
 fontWeight: FontWeight.bold),
 overflow: TextOverflow.clip,),)

hope this help someone :)

try this in windows:

pip install -U <Package_Name>

In IntelliJ:

1. Open Project Structure (?;) > Modules > YOUR MODULE -> Language level: set 9, in your case.
2. Repeat for each module.

You can ignore the peer dependency warnings by using the --force flag with Angular cli when updating dependencies.

ng update @angular/cli @angular/core --force

For a full list of options, check the docs: https://angular.io/cli/update

Although most of these previous answers will work, I suggest you explore the provider or BloC architectures, both of which have been recommended by Google.

In short, the latter will create a stream that reports to widgets in the widget tree whenever a change in the state happens and it updates all relevant views regardless of where it is updated from.

Here is a good overview you can read to learn more about the subject: https://bloclibrary.dev/#/

the problem is in the MatInputModule:

exports: [
    MatInputModule
  ]

One of possible root causes: duplicate transient dependencies that weren't properly handled by Android Studio import of multi-module projects. Check your list and remove them. For me, the fix was literally this:

--- a/project/module/build.gradle
+++ b/project/module/build.gradle
@@ -21,5 +21,4 @@ android {
 dependencies {
     implementation project(':upstream-dependency-project')
     implementation 'com.android.support:support-v4:18.0.0'
-    implementation files('libs/slf4j-android-1.6.1-RC1.jar')
 }

For each error of the form:

npm WARN {something} requires a peer of {other thing} but none is installed. You must install peer dependencies yourself.

You should:

$ npm install --save-dev "{other thing}"

Note: The quotes are needed if the {other thing} has spaces, like in this example:

npm WARN [email protected] requires a peer of rollup@>=0.66.0 <2 but none was installed.

Resolved with:

$ npm install --save-dev "rollup@>=0.66.0 <2"

You need to check the keycloak admin console for fronted configuration. It must be wrongly configured for redirect url and web origins.

If you want to import all Material modules, create your own module i.e. material.module.ts and do something like the following:

import { NgModule } from '@angular/core';_x000D_
import * as MATERIAL_MODULES from '@angular/material';_x000D_
_x000D_
export function mapMaterialModules() {_x000D_
  return Object.keys(MATERIAL_MODULES).filter((k) => {_x000D_
    let asset = MATERIAL_MODULES[k];_x000D_
    return typeof asset == 'function'_x000D_
      && asset.name.startsWith('Mat')_x000D_
      && asset.name.includes('Module');_x000D_
  }).map((k) => MATERIAL_MODULES[k]);_x000D_
}_x000D_
const modules = mapMaterialModules();_x000D_
_x000D_
@NgModule({_x000D_
    imports: modules,_x000D_
    exports: modules_x000D_
})_x000D_
export class MaterialModule { }

Then import the module into your app.module.ts

Maybe this solution ? :)

function createEnum (array) {
  return Object.freeze(array
    .reduce((obj, item) => {
      if (typeof item === 'string') {
        obj[item.toUpperCase()] = Symbol(item)
      }
      return obj
    }, {}))
}

Example:

createEnum(['red', 'green', 'blue']);

> {RED: Symbol(red), GREEN: Symbol(green), BLUE: Symbol(blue)}

Quick and dirty: just use Redux + react-redux + redux-persist + AsyncStorage for react-native.

It fits almost perfectly the react native world and works like a charm for both android and ios. Also, there is a solid community around it, and plenty of information.

For a working example, see the F8App from Facebook.

What are the different options for data persistence?

With react native, you probably want to use redux and redux-persist. It can use multiple storage engines. AsyncStorage and redux-persist-filesystem-storage are the options for RN.

There are other options like Firebase or Realm, but I never used those on a RN project.

For each, what are the limits of that persistence (i.e., when is the data no longer available)? For example: when closing the application, restarting the phone, etc.

Using redux + redux-persist you can define what is persisted and what is not. When not persisted, data exists while the app is running. When persisted, the data persists between app executions (close, open, restart phone, etc).

AsyncStorage has a default limit of 6MB on Android. It is possible to configure a larger limit (on Java code) or use redux-persist-filesystem-storage as storage engine for Android.

For each, are there differences (other than general setup) between implementing in iOS vs Android?

Using redux + redux-persist + AsyncStorage the setup is exactly the same on android and iOS.

How do the options compare for accessing data offline? (or how is offline access typically handled?)

Using redux, offiline access is almost automatic thanks to its design parts (action creators and reducers).

All data you fetched and stored are available, you can easily store extra data to indicate the state (fetching, success, error) and the time it was fetched. Normally, requesting a fetch does not invalidate older data and your components just update when new data is received.

The same apply in the other direction. You can store data you are sending to server and that are still pending and handle it accordingly.

Are there any other considerations I should keep in mind?

React promotes a reactive way of creating apps and Redux fits very well on it. You should try it before just using an option you would use in your regular Android or iOS app. Also, you will find much more docs and help for those.

For me I solved this error just by adding this line inside repository

maven { url 'https://maven.google.com' }

This error occurs when the client URL and server URL don't match, including the port number. In this case you need to enable your service for CORS which is cross origin resource sharing.

If you are hosting a Spring REST service then you can find it in the blog post CORS support in Spring Framework.

If you are hosting a service using a Node.js server then

1. Stop the Node.js server.
2. npm install cors --save

3. Add following lines to your server.js

   var cors = require('cors')
   
   app.use(cors()) // Use this after the variable declaration
   

This exception message doesn't mean it requires a primary key to be defined in your database, it means it requires a primary key to be defined in your class.

Although you've attempted to do so:

private Guid _id;
[Key]
public Guid ID
{
    get { return _id; }
}

This has no effect, as Entity Framework ignores read-only properties. It has to: when it retrieves a Fruits record from the database, it constructs a Fruit object, and then calls the property setters for each mapped property. That's never going to work for read-only properties.

You need Entity Framework to be able to set the value of ID. This means the property needs to have a setter.

Same error, I upgrade my Junit and resolve it

org.junit.jupiter:junit-jupiter-api:5.0.0-M6

to

org.junit.jupiter:junit-jupiter-api:5.0.0

I've tried everything suggested here but didn't work for me. So in case I can help anyone with a similar issue, every single tutorial I've checked is not updated to work with version 4.

Here is what I've done to make it work

import React from 'react';
import App from './App';

import ReactDOM from 'react-dom';
import {
    HashRouter,
    Route
} from 'react-router-dom';


 ReactDOM.render((
        <HashRouter>
            <div>
                <Route path="/" render={()=><App items={temasArray}/>}/>
            </div>
        </HashRouter >
    ), document.getElementById('root'));

That's the only way I have managed to make it work without any errors or warnings.

In case you want to pass props to your component for me the easiest way is this one:

 <Route path="/" render={()=><App items={temasArray}/>}/>

In class file you can either use:

module.exports = class ClassNameHere {
 print() {
  console.log('In print function');
 }
}

or you can use this syntax

class ClassNameHere{
 print(){
  console.log('In print function');
 }
}

module.exports = ClassNameHere;

On the other hand to use this class in any other file you need to do these steps. First require that file using this syntax: const anyVariableNameHere = require('filePathHere');

Then create an object const classObject = new anyVariableNameHere();

After this you can use classObject to access the actual class variables

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

This solution worked for me:

• go to tsconfig.json and add "strictNullChecks":false

The expires and add_header directives have no impact on NGINX caching the files, those are purely about what the browser sees.

What you likely want instead is:

location stuffyoudontwanttocache {
    # don't cache it
    proxy_no_cache 1;
    # even if cached, don't try to use it
    proxy_cache_bypass 1; 
}

Though usually .js etc is the thing you would cache, so perhaps you should just disable caching entirely?

i have faced same problem

my initial json

{"items":

         [
           {"id":1,
            "Name":"test4"
           },
           {"id":2,
            "Name":"test1"
           }
         ]
}

i have changed my json inside []

[{"items":

         [
           {"id":1,
            "Name":"test4"
           },
           {"id":2,
            "Name":"test1"
           }
         ]
}]

I've found a solution for width: "100%", height: "auto" if you know the aspectRatio (width / height) of the image.

Here's the code:

import { Image, StyleSheet, View } from 'react-native';

const image = () => (
    <View style={styles.imgContainer}>
        <Image style={styles.image} source={require('assets/images/image.png')} />
    </View>
);

const style = StyleSheet.create({
    imgContainer: {
        flexDirection: 'row'
    },
    image: {
        resizeMode: 'contain',
        flex: 1,
        aspectRatio: 1 // Your aspect ratio
    }
});

This is the most simplest way I could get it to work without using onLayout or Dimension calculations. You can even wrap it in a simple reusable component if needed. Give it a shot if anyone is looking for a simple implementation.

I was facing this issue on Angular 7 and the problem was after creating the module, I did not perform ng build. So I performed -

• ng build
• ng serve

and it worked.

You can use ancestor. I find that this is easier to read because the element you are actually selecting is at the end of the path.

//span[contains(text(),'someText')]/ancestor::div[contains(@class, 'measure-tab')]

Plotly is missing in this list. I've linked the python binding page. It definitively has animated and interative 3D Charts. And since it is Open Source most of that is available offline. Of course it is working with Jupyter

I think it's possible in Java 9:

animalMap.entrySet().stream()
                .forEach(
                        pair -> Optional.ofNullable(pair.getValue())
                                .ifPresentOrElse(v -> myMap.put(pair.getKey(), v), v -> myList.add(pair.getKey())))
                );

Need the ifPresentOrElse for it to work though. (I think a for loop looks better.)

Considering all of your API requests located with a url pattern of /api/.. you can tell spring to secure only this url pattern by using below configuration. Which means that you are telling spring what to secure instead of what to ignore.

@Override
protected void configure(HttpSecurity http) throws Exception {
  http
    .csrf().disable()
     .authorizeRequests()
      .antMatchers("/api/**").authenticated()
      .anyRequest().permitAll()
      .and()
    .httpBasic().and()
    .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}

private void sendNotification(String message) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    int requestCode = 0;
    PendingIntent pendingIntent = PendingIntent.getActivity(this, requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.URI_COLUMN_INDEX);
    NotificationCompat.Builder noBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentText(message)
            .setColor(getResources().getColor(R.color.colorPrimaryDark))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle("FCM Message")
            .setContentText("hello").setLargeIcon(((BitmapDrawable) getResources().getDrawable(R.drawable.dog)).getBitmap())
            .setStyle(new NotificationCompat.BigPictureStyle()
                    .bigPicture(((BitmapDrawable) getResources().getDrawable(R.drawable.dog)).getBitmap()))
            .setAutoCancel(true)
            .setSound(sound)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, noBuilder.build());

If you use JDK 8+, there is a one line lambda solution:

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors().configurationSource(request -> new CorsConfiguration().applyPermitDefaultValues());
}

In android/app/build.gradle

android {

compileSdkVersion 23

 buildToolsVersion '23.0.0'

    defaultConfig {
        applicationId "com.dkm.example"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

Put this inside your defaultConfig:

multiDexEnabled true 

it works for me

Sometimes the "Bundle Identifier" in Xcode is changing due to some things that you made. Make sure the Bundle Identifier you defined in your Apple Developer account is exactly the same as the one in Xcode.

Perhaps I didn't see the answer, but this is how I do it.

1. .Net Core --> Properties --> launchSettings.json

You need to have change these values

"windowsAuthentication": true, // needs to be true
"anonymousAuthentication": false,  // needs to be false 

Startup.cs --> ConfigureServices(...)

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

MVC or Web Api Controller

private readonly IHttpContextAccessor _httpContextAccessor;
//constructor then
_httpContextAccessor = httpContextAccessor;

Controller method:

string userName = _httpContextAccessor.HttpContext.User.Identity.Name;

Result is userName e.g. = Domain\username

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

Alternative Solution:

This answer of Thierry Templier is an alternative way to get around the problem.

After some questions with Thierry Templier, I came to the following working example that meets my expectations as an alternative to inheritance limitation mentioned in this question:

1 - Create custom decorator:

export function CustomComponent(annotation: any) {
  return function (target: Function) {
    var parentTarget = Object.getPrototypeOf(target.prototype).constructor;
    var parentAnnotations = Reflect.getMetadata('annotations', parentTarget);

    var parentAnnotation = parentAnnotations[0];
    Object.keys(parentAnnotation).forEach(key => {
      if (isPresent(parentAnnotation[key])) {
        // verify is annotation typeof function
        if(typeof annotation[key] === 'function'){
          annotation[key] = annotation[key].call(this, parentAnnotation[key]);
        }else if(
        // force override in annotation base
        !isPresent(annotation[key])
        ){
          annotation[key] = parentAnnotation[key];
        }
      }
    });

    var metadata = new Component(annotation);

    Reflect.defineMetadata('annotations', [ metadata ], target);
  }
}

2 - Base Component with @Component decorator:

@Component({
  // create seletor base for test override property
  selector: 'master',
  template: `
    <div>Test</div>
  `
})
export class AbstractComponent {

}

3 - Sub component with @CustomComponent decorator:

@CustomComponent({
  // override property annotation
  //selector: 'sub',
  selector: (parentSelector) => { return parentSelector + 'sub'}
})
export class SubComponent extends AbstractComponent {
  constructor() {
  }
}

Plunkr with complete example.

Just to give some examples. Let's say you modify the password for an user called 'alex'. You can modify this password in several ways. For instance:

mysql> update* user set password=PASSWORD('test!23') where user='alex'; 
mysql> flush privileges;

Here you used UPDATE. If you use INSERT, UPDATE or DELETE on grant tables directly you need use FLUSH PRIVILEGES in order to reload the grant tables.

Or you can modify the password like this:

mysql> set password for 'alex'@'localhost'= password('test!24');

Here it's not necesary to use "FLUSH PRIVILEGES;" If you modify the grant tables indirectly using account-management statements such as GRANT, REVOKE, SET PASSWORD, or RENAME USER, the server notices these changes and loads the grant tables into memory again immediately.

You could just comment the maven dependency for a while:

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>
<!--        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>-->
</dependencies>

It worked fine for me

Disabling it from application.properties is deprecated for Spring Boot 2.0

Using the Cors option in the API gateway, I used the following settings shown above

Also, note, that your function must return a HTTP status 200 in response to an OPTIONS request, or else CORS will also fail.

I came upon a similar issue recently and following Fabian's advice actually led me to the solution. Turns out with client certs you have to ensure two things:

1. The private key is actually being exported as part of the cert.

2. The application pool identity running the app has access to said private key.

In our case I had to:

1. Import the pfx file into the local server store while checking the export checkbox to ensure the private key was sent out.
2. Using MMC console, grant the service account used access to the private key for the cert.

The trusted root issue explained in other answers is a valid one, it was just not the issue in our case.

EncodedParams variable is redefined as params variable will not work. You need to have same predefined call to variable, otherwise it looks possible with a little more work. Cheers! json is not used to its full capabilities in php there are better ways to call json which I don't recall at the moment.

I found that along with setting the -p port values, Docker for Windows uses vpnkit and inbound traffic for it was disabled by default on my host machine's firewall. After enabling the inbound TCP rules for vpnkit I was able to access my containers from other machines on the local network.

You opened the file in binary mode:

The following code will throw a TypeError: a bytes-like object is required, not 'str'.

for line in lines:
    print(type(line))# <class 'bytes'>
    if 'substring' in line:
       print('success')

The following code will work - you have to use the decode() function:

for line in lines:
    line = line.decode()
    print(type(line))# <class 'str'>
    if 'substring' in line:
       print('success')

Only allow numbers using a regular expression

<TextInput 
  keyboardType = 'numeric'
  onChangeText = {(e)=> this.onTextChanged(e)}
  value = {this.state.myNumber}
/> 

onTextChanged(e) {
  if (/^\d+$/.test(e.toString())) { 
    this.setState({ myNumber: e });
  }
}

You might want to have more than one validation

<TextInput 
  keyboardType = 'numeric'
  onChangeText = {(e)=> this.validations(e)}
  value = {this.state.myNumber}
/> 

numbersOnly(e) {
    return /^\d+$/.test(e.toString()) ? true : false
}

notZero(e) {
    return /0/.test(parseInt(e)) ? false : true
}

validations(e) {
    return this.notZero(e) && this.numbersOnly(e)
        ? this.setState({ numColumns: parseInt(e) })
        : false
}

This error also happens if you added a second "script" key in the package.json file. If you just leave one "script" key in the package.json the error disappears.

Go to laravelFolder/bootstrap/cache then rename config.php to anything you want eg. config.php_old and reload your site. That should work like voodoo.

For some projects it's easier to set your target to es6 in your tsconfig.json.

{
  "compilerOptions": {
    "target": "es6",
    ...

That version number (51.0) indicates that you are trying to run classes compiled for Java 7. You will need to recompile them for Java 6.

Note, however, that some features may no longer be compatible with Java 6, which is very old, and no longer (publicly) supported by Oracle.

Since the name is likely to change in future versions of Android (currently the latest is AppCompatActivity but it will probably change at some point), I believe a good thing to have is a class Activity that extends AppCompatActivity and then all your activities extend from that one. If tomorrow, they change the name to AppCompatActivity2 for instance you will have to change it just in one place.

For MacOS this worked for me without the need to hardcode a particular Java version:

launchctl setenv JAVA_HOME "$(jenv javahome)"

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:

• Start your intellij from terminal /Applications/IntelliJ IDEA 14.app/Contents/MacOS (this will pick your bash env variables)
• Add login env variable by executing: launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"

To directly answer your question, you can add launchctl line in your ~/.bash_profile

As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.

below is an generic example

    //base class
    class A {
        
        // The virtual method
        protected virtualStuff1?():void;
    
        public Stuff2(){
            //Calling overridden child method by parent if implemented
            this.virtualStuff1 && this.virtualStuff1();
            alert("Baseclass Stuff2");
        }
    }
    
    //class B implementing virtual method
    class B extends A{
        
        // overriding virtual method
        public virtualStuff1()
        {
            alert("Class B virtualStuff1");
        }
    }
    
    //Class C not implementing virtual method
    class C extends A{

I've been using Typescript in my current angular project for about a year and a half and while there are a few issues with definitions every now and then the DefinitelyTyped project does an amazing job at keeping up with the latest versions of most popular libraries.

Having said that there is a definite learning curve when transitioning from vanilla JavaScript to TS and you should take into account the ability of you and your team to make that transition. Also if you are going to be using angular 1.x most of the examples you will find online will require you to translate them from JS to TS and overall there are not a lot of resources on using TS and angular 1.x together right now.

If you plan on using angular 2 there are a lot of examples using TS and I think the team will continue to provide most of the documentation in TS, but you certainly don't have to use TS to use angular 2.

ES6 does have some nice features and I personally plan on getting more familiar with it but I would not consider it a production-ready language at this point. Mainly due to a lack of support by current browsers. Of course, you can write your code in ES6 and use a transpiler to get it to ES5, which seems to be the popular thing to do right now.

Overall I think the answer would come down to what you and your team are comfortable learning. I personally think both TS and ES6 will have good support and long futures, I prefer TS though because you tend to get language features quicker and right now the tooling support (in my opinion) is a little better.

I have faced the same issue. I have changed the maven-assembly-plugin to 3.1.1 from 2.5.3 in POM.xml

Proposed version should be done under plugin section. enter code here artifact Id for maven-assembly-plugin

Placing setOnClickListener in onStart method solved the problem for me. Checkout "Android Lifecycle concept" for further clarification

In CPython, range(...).__contains__ (a method wrapper) will eventually delegate to a simple calculation which checks if the value can possibly be in the range. The reason for the speed here is we're using mathematical reasoning about the bounds, rather than a direct iteration of the range object. To explain the logic used:

1. Check that the number is between start and stop, and
2. Check that the stride value doesn't "step over" our number.

For example, 994 is in range(4, 1000, 2) because:

1. 4 <= 994 < 1000, and
2. (994 - 4) % 2 == 0.

The full C code is included below, which is a bit more verbose because of memory management and reference counting details, but the basic idea is there:

static int
range_contains_long(rangeobject *r, PyObject *ob)
{
    int cmp1, cmp2, cmp3;
    PyObject *tmp1 = NULL;
    PyObject *tmp2 = NULL;
    PyObject *zero = NULL;
    int result = -1;

    zero = PyLong_FromLong(0);
    if (zero == NULL) /* MemoryError in int(0) */
        goto end;

    /* Check if the value can possibly be in the range. */

    cmp1 = PyObject_RichCompareBool(r->step, zero, Py_GT);
    if (cmp1 == -1)
        goto end;
    if (cmp1 == 1) { /* positive steps: start <= ob < stop */
        cmp2 = PyObject_RichCompareBool(r->start, ob, Py_LE);
        cmp3 = PyObject_RichCompareBool(ob, r->stop, Py_LT);
    }
    else { /* negative steps: stop < ob <= start */
        cmp2 = PyObject_RichCompareBool(ob, r->start, Py_LE);
        cmp3 = PyObject_RichCompareBool(r->stop, ob, Py_LT);
    }

    if (cmp2 == -1 || cmp3 == -1) /* TypeError */
        goto end;
    if (cmp2 == 0 || cmp3 == 0) { /* ob outside of range */
        result = 0;
        goto end;
    }

    /* Check that the stride does not invalidate ob's membership. */
    tmp1 = PyNumber_Subtract(ob, r->start);
    if (tmp1 == NULL)
        goto end;
    tmp2 = PyNumber_Remainder(tmp1, r->step);
    if (tmp2 == NULL)
        goto end;
    /* result = ((int(ob) - start) % step) == 0 */
    result = PyObject_RichCompareBool(tmp2, zero, Py_EQ);
  end:
    Py_XDECREF(tmp1);
    Py_XDECREF(tmp2);
    Py_XDECREF(zero);
    return result;
}

static int
range_contains(rangeobject *r, PyObject *ob)
{
    if (PyLong_CheckExact(ob) || PyBool_Check(ob))
        return range_contains_long(r, ob);

    return (int)_PySequence_IterSearch((PyObject*)r, ob,
                                       PY_ITERSEARCH_CONTAINS);
}

The "meat" of the idea is mentioned in the line:

/* result = ((int(ob) - start) % step) == 0 */ 

As a final note - look at the range_contains function at the bottom of the code snippet. If the exact type check fails then we don't use the clever algorithm described, instead falling back to a dumb iteration search of the range using _PySequence_IterSearch! You can check this behaviour in the interpreter (I'm using v3.5.0 here):

>>> x, r = 1000000000000000, range(1000000000000001)
>>> class MyInt(int):
...     pass
... 
>>> x_ = MyInt(x)
>>> x in r  # calculates immediately :) 
True
>>> x_ in r  # iterates for ages.. :(

I solved it putting a old version of maven (2.x), using brew:

brew uninstall maven
brew tap homebrew/versions 
brew install maven2

To fix this issue you would have to download the file locally and run a cron job to keep updating. Note: this doesn't make your website any faster at all so its best to just ignore it.

use .loc instead of apply.

it improves vectorization.

.loc works in simple manner, mask rows based on the condition, apply values to the freeze rows.

I faced with same problem. Solution that worked for me. If you use v7.Toolbar you must use theme extended from Theme.AppCompat.* You can't use theme extended from android:Theme.Material.* because they have different style attributes.

Hope it will helpful.

Is there any way that I can start android emulator for intel x86 atom Without hardware acceleration on windows 8

Not with the standard Android SDK emulator, as it requires Intel's HAXM, and HAXM wants virtualization extensions to be enabled.

Whether Genymotion or something else from another independent developer can support your desired combination, I cannot say.

Tried most of the things here to no avail, but finally found a fix for my machine, so thought I'd share it:

Following previous advice in another question, I had used netsh to add :: to iplisten. It turns out undoing that was my solution, by simply replacing add in their advice:

netsh http delete iplisten ipaddress=::

You can also do this manually by deleting HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\ListenOnlyList from the registry and restarting the service/your PC.

webpack solution

If you got this error while working in React with webpack and HMR.

You need to create template index.html and save it in src folder:

<html>
    <body>
       <div id="root"></root>
    </body>
</html>

Now when we have template with id="root" we need to tell webpack to generate index.html which will mirror our index.html file.

To do that:

plugins: [
    new HtmlWebpackPlugin({
        title: "Application name",
        template: './src/index.html'
    })
],

template property will tell webpack how to build index.html file.

I think what you want is something like:

=INDEX(B:B,MATCH(C2,A:A,0))  

I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B.

Initially ,I have commented my new fields which is causing those errors, and run python manage.py makemigrations and then python manage.py migrate to actually delete those new fields.

class FootballScore(models.Model):
    team = models.ForeignKey(Team, related_name='teams_football', on_delete=models.CASCADE)
    # match_played = models.IntegerField(default='0')
    # lose = models.IntegerField(default='0')
    win = models.IntegerField(default='0')
    # points = models.IntegerField(default='0')

class FootballScore(models.Model):
    team = models.ForeignKey(Team, related_name='teams_football', on_delete=models.CASCADE)
    match_played = models.IntegerField(default='0')
    lose = models.IntegerField(default='0')
    win = models.IntegerField(default='0')
    points = models.IntegerField(default='0')

Then i freshly uncommented them and run python manage.py makemigrations and python manage.py migrate and boom. It worked for me. :)

I am using Mac OS X 10.9.5. This is how I manage multiple JDK/JRE on my machine when I need one version to run application A and use another version for application B.

I created the following script after getting some help online.

#!bin/sh
function setjdk() {
  if [ $# -ne 0 ]; then
   removeFromPath '/Library/Java/JavaVirtualMachines/'
   if [ -n "${JAVA_HOME+x}" ]; then
    removeFromPath $JAVA_HOME
   fi
   export JAVA_HOME=/Library/Java/JavaVirtualMachines/$1/Contents/Home
   export PATH=$JAVA_HOME/bin:$PATH
  fi
 }
 function removeFromPath() {
  export PATH=$(echo $PATH | sed -E -e "s;:$1;;" -e "s;$1:?;;")
 }
#setjdk jdk1.8.0_60.jdk
setjdk jdk1.7.0_15.jdk

I put the above script in .profile file. Just open terminal, type vi .profile, append the script with the above snippet and save it. Once your out type source .profile, this will run your profile script without you having to restart the terminal. Now type java -version it should show 1.7 as your current version. If you intend to change it to 1.8 then comment the line setjdk jdk1.7.0_15.jdk and uncomment the line setjdk jdk1.8.0_60.jdk. Save the script and run it again with source command. I use this mechanism to manage multiple versions of JDK/JRE when I have to compile 2 different Maven projects which need different java versions.

Lodash _.isEqual allows you to do that:

var_x000D_
remoteJSON = {"allowExternalMembers": "false", "whoCanJoin": "CAN_REQUEST_TO_JOIN"},_x000D_
    localJSON = {"whoCanJoin": "CAN_REQUEST_TO_JOIN", "allowExternalMembers": "false"};_x000D_
    _x000D_
console.log( _.isEqual(remoteJSON, localJSON) );

curl -u username:password http://
curl -u username http://

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

http://curl.haxx.se/docs/manpage.html#-u

Note that you do not need --basic flag as it is the default.

Try this:

$NameRegex = "chalmw-dm"  
$NameR = "$($NameRegex)*"
Get-ADComputer -Filter {name -like $NameR -and Enabled -eq $True}

I coded up an equivalent C program to experiment, and I can confirm this strange behaviour. What's more, gcc believes the 64-bit integer (which should probably be a size_t anyway...) to be better, as using uint_fast32_t causes gcc to use a 64-bit uint.

I did a bit of mucking around with the assembly:
Simply take the 32-bit version, replace all 32-bit instructions/registers with the 64-bit version in the inner popcount-loop of the program. Observation: the code is just as fast as the 32-bit version!

This is obviously a hack, as the size of the variable isn't really 64 bit, as other parts of the program still use the 32-bit version, but as long as the inner popcount-loop dominates performance, this is a good start.

I then copied the inner loop code from the 32-bit version of the program, hacked it up to be 64 bit, fiddled with the registers to make it a replacement for the inner loop of the 64-bit version. This code also runs as fast as the 32-bit version.

My conclusion is that this is bad instruction scheduling by the compiler, not actual speed/latency advantage of 32-bit instructions.

(Caveat: I hacked up assembly, could have broken something without noticing. I don't think so.)

in my case, after encrypting password,I forgot to put settings-security.xml into ~/.m2?

Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.

in most cases, got no authentication method error when using the wrong username for logging in. But I do find something else if you still struggle with connection issue and you have tried all the options above.

I created couple Linux VM and try to reproduce such connection issue, one thing I found is, when AWS asked you name your key pair, DO NOT user blank space (" ") and dot (".") in key pair name, even AWS actually allow you to do so.

ex. when I named the key pair as "AWS.FREE.LINUX", connection always be refused. When I named as "AWS_FREE_LINUX", everything works fine.

Hope this will help a little bit.

Also simple and easy:

Start-Sleep 10

Using brew

brew install Caskroom/cask/java

You could also have embed all of your template views into your main html file. For Example:

<body ng-app="testApp">
  <h1>Test App</h1>
  <div ng-view></div>
  <script type = "text/ng-template" id = "index.html">
    <h1>Index Page</h1>
    <p>{{message}}</p>
  </script>
  <script type = "text/ng-template" id = "home.html">
    <h1>Home Page</h1>
    <p>{{message}}</p>
  </script>
</body>

This way if each template requires a different controller then you can still use the angular-router. See this plunk for a working example http://plnkr.co/edit/9X0fT0Q9MlXtHVVQLhgr?p=preview

This way once the application is sent from the server to your client, it is completely self contained assuming that it doesn't need to make any data requests, etc.

You can locate a file named listener.ora under the installation folder oraclexe\app\oracle\product\11.2.0\server\network\ADMIN It contains the following entries

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = Codemaker-PC)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

You should verify the HOST (Here it is Codemaker-PC) should be the computer name. If it's not correct the change it as computer name.

then try the following command on the command prompt run as administrator,

lsnrctl start

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

func partition(inout list : [Int], low: Int, high : Int) -> Int {
    let pivot = list[high]
    var j = low
    var i = j - 1
    while j < high {
        if list[j] <= pivot{
            i += 1
            (list[i], list[j]) = (list[j], list[i])
        }
        j += 1
    }
    (list[i+1], list[high]) = (list[high], list[i+1])
    return i+1
}

func quikcSort(inout list : [Int] , low : Int , high : Int) {

    if low < high {
        let pIndex = partition(&list, low: low, high: high)
        quikcSort(&list, low: low, high: pIndex-1)
        quikcSort(&list, low: pIndex + 1, high: high)
    }
}

var list = [7,3,15,10,0,8,2,4]
quikcSort(&list, low: 0, high: list.count-1)

var list2 = [ 10, 0, 3, 9, 2, 14, 26, 27, 1, 5, 8, -1, 8 ]
quikcSort(&list2, low: 0, high: list2.count-1)

var list3 = [1,3,9,8,2,7,5]
quikcSort(&list3, low: 0, high: list3.count-1) 

This is my Blog about Quick Sort- Github sample Quick-Sort

You can take a look at Lomuto's partitioning algorithm in Partitioning the list. Written in Swift.

You are doing a cartesian join. This means that if you wouldn't have even have the single where clause, the number of results you get would be book_customer size times books size times book_order size times publisher size.

In order words, the result set gets blown up because you didn't add meaningful join clauses. Your correct query should look something like this:

SELECT bc.firstname, bc.lastname, b.title, TO_CHAR(bo.orderdate, 'MM/DD/YYYY') "Order Date", p.publishername
FROM book_customer bc, books b, book_order bo, publisher p
WHERE bc.book_id = b.book_id
AND bo.book_id = b.book_id
(etc.)
AND publishername = 'PRINTING IS US';

Note: usually it is adviced to not use the implicit joins like in this query, but use the INNER JOIN syntax. I am assuming however, that this syntax is used in your study material so I've left it in.

There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

• With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.

  mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
  

• With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

  ## Prepare a temporary script that will serve as an editor.
  
  ## This script will be passed to ed.
  temp_script=$(mktemp)
  cat <<'EOF' >>"$temp_script"
  1a
  Content-Type: text/html
  .
  $r test.html
  w
  q
  EOF
  ## Call mailx, and tell it to invoke the editor script
  EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
  ~e
  .
  EOF
  rm -f "$temp_script"
  

• With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

• This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.

• When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html

EOF

One thing I mentioned in another thread that is worth pointing out -- if you are building different versions of your app for different densities, you should know about the "mipmap" resource directory. This is exactly like "drawable" resources, except it does not participate in density stripping when creating the different apk targets.

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:

function get-loggedonuser ($computername){

#mjolinor 3/17/10

$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'

$logontype = @{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}

$logon_sessions = @(gwmi win32_logonsession -ComputerName $computername)
$logon_users = @(gwmi win32_loggedonuser -ComputerName $computername)

$session_user = @{}

$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}


$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)

$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime

$loggedonuser
}

}

Just clear the plots and try executing the code again...It worked for me

Better you update your eclipse by clicking it on help >> check for updates, also you can start eclipse by entering command in command prompt eclipse -clean.
Hope this will help you.

You can sum up the values of a BigDecimal stream using a reusable Collector named summingUp:

BigDecimal sum = bigDecimalStream.collect(summingUp());

The Collector can be implemented like this:

public static Collector<BigDecimal, ?, BigDecimal> summingUp() {
    return Collectors.reducing(BigDecimal.ZERO, BigDecimal::add);
}

you put resource-ref in the description tag in web.xml

You could use: cordova plugins list | awk '{print $1}' | xargs cordova plugins rm

and use cordova plugins list to verify if plugins are all removed.

It occurred because you tried to create a foreign key from tblDomare.PersNR to tblBana.BanNR but/and the values in tblDomare.PersNR didn't match with any of the values in tblBana.BanNR. You cannot create a relation which violates referential integrity.

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }

It turns out, after messing around with all of the settings in the test business account, that one (or more) of the fraud related settings in the payment receiving preferences / security settings screens were causing the test payments to fail (without any useful error).

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

You can achieve this by adding border class of bootstrap

like for border left ,you can use border-left

working code

<div class="row">
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="one"><h5>Rich Media Ad Production</h5><img src="images/richmedia.png"></div>
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="two"><h5>Web Design & Development</h5> <img src="images/web.png" ></div>               
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="three"><h5>Mobile Apps Development</h5> <img src="images/mobile.png"></div>
    <div class="col-xs-6 col-sm-6 col-md-3 text-center rightspan  border-bottom" id="four"><h5>Creative Design</h5> <img src="images/mobile.png"> </div>

In my multi-module project, the problem was that version of "com.android.support:appcompat-v7" in module A was "22.0.0", but in B - "22.2.0".

Solution: make sure
1. version of common libraries is same among modules.
2. each of modules compiles without any errors (try to build each of them from CLI).

for me i solved it like the following In Visual Studio 2015 : From View menu click Other Windows then click Package Manager Console then run the following commands :

PM> enable-migrations

Migrations have already been enabled in project 'mvcproject'. To overwrite the existing migrations configuration, use the -Force parameter.

PM> enable-migrations -Force

Checking if the context targets an existing database... Code First Migrations enabled for project mvcproject.

then add the migration name under the migration folder it will add the class you need in Solution Explorer by run the following command

PM>Add-migration AddColumnUser

Finally update the database

PM> update-database 

In my case we were setting the div id as a number and setting the href="#123", this did not work.. adding a prefix to the id helped.

Example: This did not work-

<li> <a data-toggle="tab" href="#@i"> <li/>
...
<div class="tab-pane" id="#@i">

This worked:

<li><a data-toggle="tab" href="#prefix@i"><li/>
...
<div class="tab-pane" id="#prefix@i">

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

your approach is pretty good...

I created an arrayList from it and I somehow can't find a way to store this information into a JTable.

The DefaultTableModel doesn't support displaying custom Objects stored in an ArrayList. You need to create a custom TableModel.

You can check out the Bean Table Model. It is a reusable class that will use reflection to find all the data in your FootballClub class and display in a JTable.

Or, you can extend the Row Table Model found in the above link to make is easier to create your own custom TableModel by implementing a few methods. The JButtomTableModel.java source code give a complete example of how you can do this.

Eureka ! Finally I found a solution on this.

This is caused by Windows update that stops any 32-bit processes from consuming more than 1200 MB on a 64-bit machine. The only way you can repair this is by using the System Restore option on Win 7.

Start >> All Programs >> Accessories >> System Tools >> System Restore.

And then restore to a date on which your Java worked fine. This worked for me. What is surprising here is Windows still pushes system updates under the name of "Critical Updates" even when you disable all windows updates. ^&%)#* Windows :-)

For my situation, I switched the value of "fork" to false, such as <fork>false</fork>. I do not understand why, hope someone could explain to me. Thanks in advance.

Maven needs to be able to access various Maven repositories in order to download artifacts to the local repository. If your local system is accessing the Internet through a proxy host, you might need to explicitly specify the proxy settings for Maven by editing the Maven settings.xml file. Maven builds ignore the IDE proxy settings that are set in the Options window. For many common cases, just passing -Djava.net.useSystemProxies=true to Maven should suffice to download artifacts through the system's configured proxy. NetBeans 7.1 will offer to configure this flag for you if it detects a possible proxy problem. https://netbeans.org/bugzilla/show_bug.cgi?id=194916 has discussion.

In my case this fixed the issue

1. Go to Project Properties by clicking F4 on the project name
2. Set SSLEnabled = true

Project Properties Image

Is your NavigationDrawerFragment extending the android.support.v4.app.Fragment? In other words, are you importing the correct package?

import android.support.v4.app.Fragment;

set permission on application directory solve this issue with me

To set this permission, right click on the App_Data folder (or whichever other folder you have put the file in) and select Properties. Look for the Security tab. If you can't see it, you need to go to My Computer, then click Tools and choose Folder Options.... then click the View tab. Scroll to the bottom and uncheck "Use simple file sharing (recommended)". Back to the Security tab, you need to add the relevant account to the Group or User Names box. Click Add.... then click Advanced, then Find Now. The appropriate account should be listed. Double click it to add it to the Group or User Names box, then check the Modify option in the permissions. That's it. You are done.

To my humble understanding this error arises with different scenarios

1. you have selected the wrong port or you haven't at all. go to tools>ports ans select the com port with your Arduino connected to
2. you have selected the wrong board. go to tools>board and look for the right board
3. you have one of these arduino's replicas or you don't have the boot-loader installed on the micro-controller. I don't know the solution to this! if you know please edit my post and add the instructions.
4. (windows only) you don't have the right drivers installed. you need to update them manually.

5. sometimes when you have wires connected to the board this happens. you need to separate the board from any breadboard or wires you have installed and try uploading again. It seems pins 0 (RX) and 1 (TX), which can be used for serial communication, are problematic and better to be free while uploading the code.

6. Sometimes it happens randomly for no specific reasons!

There are all kind of solutions all over the internet, sometimes hard to tell the difference with magic! Maybe Arduino team should think of better compiler errors helping users differentiate between these different causes.

The same problem happened to me and none of the solutions above worked. What happened was that I was using an Arduino uno and everything was fine, but when I bough an Arduino Mega 2560, no matter what sketch I tried to upload I got the error:

avrdude: stk500v2_ReceiveMessage(): timeout

And it was just on one of my windows computers and the other one was just ok out of the box.

Solution:

What solved my problem was to go to tools>boards>Boards Manager... and then on top left of the opened windows select "updatable" in "Type" section. Then select the items in the list and press update on right.

I'm not sure if this will solve everyone problem, but it at least solved mine.

import csv
from sys import argv

d = open("mydata.csv", "r")

db = []

for line in csv.reader(d):
    db.append(line)

# the rest of your code with 'db' filled with your list of lists as rows and columbs of your csv file.

This problem becomes more complex when you give the user 2 possibilities to submit the form:

1. by clicking on an ad hoc button
2. by hitting Enter key

In such a case you will need a function which detects the pressed key in which you will submit the form if Enter key was hit.

And now comes the problem with IE (in any case version 11) Remark: This issue does not exist with Chrome nor with FireFox !

• When you click the submit button the form is submitted once; fine.
• When you hit Enter the form is submitted twice ... and your servlet will be executed twice. If you don't have PRG (post redirect get) architecture serverside the result might be unexpected.

Even though the solution looks trivial, it tooks me many hours to solve this problem, so I hope it might be usefull for other folks. This solution has been successfully tested, among others, on IE (v 11.0.9600.18426), FF (v 40.03) & Chrome (v 53.02785.143 m 64 bit)

The source code HTML & js are in the snippet. The principle is described there. Warning:

You can't test it in the snippet because the post action is not defined and hitting Enter key might interfer with stackoverflow.

If you faced this issue, then just copy/paste js code to your environment and adapt it to your context.

Quick Answer:

The simplest way to get row counts per group is by calling .size(), which returns a Series:

df.groupby(['col1','col2']).size()

Usually you want this result as a DataFrame (instead of a Series) so you can do:

df.groupby(['col1', 'col2']).size().reset_index(name='counts')

If you want to find out how to calculate the row counts and other statistics for each group continue reading below.

Detailed example:

Consider the following example dataframe:

In [2]: df
Out[2]: 
  col1 col2  col3  col4  col5  col6
0    A    B  0.20 -0.61 -0.49  1.49
1    A    B -1.53 -1.01 -0.39  1.82
2    A    B -0.44  0.27  0.72  0.11
3    A    B  0.28 -1.32  0.38  0.18
4    C    D  0.12  0.59  0.81  0.66
5    C    D -0.13 -1.65 -1.64  0.50
6    C    D -1.42 -0.11 -0.18 -0.44
7    E    F -0.00  1.42 -0.26  1.17
8    E    F  0.91 -0.47  1.35 -0.34
9    G    H  1.48 -0.63 -1.14  0.17

First let's use .size() to get the row counts:

In [3]: df.groupby(['col1', 'col2']).size()
Out[3]: 
col1  col2
A     B       4
C     D       3
E     F       2
G     H       1
dtype: int64

Then let's use .size().reset_index(name='counts') to get the row counts:

In [4]: df.groupby(['col1', 'col2']).size().reset_index(name='counts')
Out[4]: 
  col1 col2  counts
0    A    B       4
1    C    D       3
2    E    F       2
3    G    H       1

Including results for more statistics

When you want to calculate statistics on grouped data, it usually looks like this:

In [5]: (df
   ...: .groupby(['col1', 'col2'])
   ...: .agg({
   ...:     'col3': ['mean', 'count'], 
   ...:     'col4': ['median', 'min', 'count']
   ...: }))
Out[5]: 
            col4                  col3      
          median   min count      mean count
col1 col2                                   
A    B    -0.810 -1.32     4 -0.372500     4
C    D    -0.110 -1.65     3 -0.476667     3
E    F     0.475 -0.47     2  0.455000     2
G    H    -0.630 -0.63     1  1.480000     1

The result above is a little annoying to deal with because of the nested column labels, and also because row counts are on a per column basis.

To gain more control over the output I usually split the statistics into individual aggregations that I then combine using join. It looks like this:

In [6]: gb = df.groupby(['col1', 'col2'])
   ...: counts = gb.size().to_frame(name='counts')
   ...: (counts
   ...:  .join(gb.agg({'col3': 'mean'}).rename(columns={'col3': 'col3_mean'}))
   ...:  .join(gb.agg({'col4': 'median'}).rename(columns={'col4': 'col4_median'}))
   ...:  .join(gb.agg({'col4': 'min'}).rename(columns={'col4': 'col4_min'}))
   ...:  .reset_index()
   ...: )
   ...: 
Out[6]: 
  col1 col2  counts  col3_mean  col4_median  col4_min
0    A    B       4  -0.372500       -0.810     -1.32
1    C    D       3  -0.476667       -0.110     -1.65
2    E    F       2   0.455000        0.475     -0.47
3    G    H       1   1.480000       -0.630     -0.63

Footnotes

The code used to generate the test data is shown below:

In [1]: import numpy as np
   ...: import pandas as pd 
   ...: 
   ...: keys = np.array([
   ...:         ['A', 'B'],
   ...:         ['A', 'B'],
   ...:         ['A', 'B'],
   ...:         ['A', 'B'],
   ...:         ['C', 'D'],
   ...:         ['C', 'D'],
   ...:         ['C', 'D'],
   ...:         ['E', 'F'],
   ...:         ['E', 'F'],
   ...:         ['G', 'H'] 
   ...:         ])
   ...: 
   ...: df = pd.DataFrame(
   ...:     np.hstack([keys,np.random.randn(10,4).round(2)]), 
   ...:     columns = ['col1', 'col2', 'col3', 'col4', 'col5', 'col6']
   ...: )
   ...: 
   ...: df[['col3', 'col4', 'col5', 'col6']] = \
   ...:     df[['col3', 'col4', 'col5', 'col6']].astype(float)
   ...: 

Disclaimer:

If some of the columns that you are aggregating have null values, then you really want to be looking at the group row counts as an independent aggregation for each column. Otherwise you may be misled as to how many records are actually being used to calculate things like the mean because pandas will drop NaN entries in the mean calculation without telling you about it.

Another example. When building a complex map of maps, the computeIfAbsent() method is a replacement for map's get() method. Through chaining of computeIfAbsent() calls together, missing containers are constructed on-the-fly by provided lambda expressions:

  // Stores regional movie ratings
  Map<String, Map<Integer, Set<String>>> regionalMovieRatings = new TreeMap<>();

  // This will throw NullPointerException!
  regionalMovieRatings.get("New York").get(5).add("Boyhood");

  // This will work
  regionalMovieRatings
    .computeIfAbsent("New York", region -> new TreeMap<>())
    .computeIfAbsent(5, rating -> new TreeSet<>())
    .add("Boyhood");

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

I am looking for a way to create a select without repeating the conditional query.

I'm assuming that you don't want to repeat Foo-stuff+bar. You could put your calculation into a derived table:

SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END 
FROM (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable) AS a

A common table expression would work just as well:

WITH a AS (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable)
SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END    
FROM a

Also, each part of your switch should return the same datatype, so you may have to cast one or more cases.

I have a workaround that seems reasonably clean to me. So I'm answering my own question.

Since 0 as the first section header's height doesn't work, I return 1. Then I use the contentInset to hide that height underneath the navigation bar.

Objective-C:

- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    if (section == 0)
            return 1.0f;
    return 32.0f;
}

- (NSString*) tableView:(UITableView *) tableView titleForHeaderInSection:(NSInteger)section
{
    if (section == 0) {
        return nil;
    } else {
        // return some string here ...
    }
}

- (void) viewDidLoad
{
    [super viewDidLoad];

     self.tableView.contentInset = UIEdgeInsetsMake(-1.0f, 0.0f, 0.0f, 0.0);
}

Swift:

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return section == 0 ? 1.0 : 32
}

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.contentInset = UIEdgeInsets(top: -1, left: 0, bottom: 0, right: 0)
}

I experienced the System.TypeInitializationException due to a different error in my .NET framework 4 project's app.config. Thank you to pStan for getting me to look at the app.config. My configSections were properly defined. However, an undefined element within one of the sections caused the exception to be thrown.

Bottom line is that problems in the app.config can generated this very misleading TypeInitializationException.

A more meaningful ConfigurationErrorsException can be generated by the same error in the app.config by waiting to access the config values until you are within a method rather than at the class level of the code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;
using System.Collections.Specialized;

namespace ConfigTest
{
    class Program
    {
        public static string machinename;
        public static string hostname;
        public static NameValueCollection _AppSettings;

        static void Main(string[] args)
        {
            machinename = System.Net.Dns.GetHostName().ToLower();
            hostname = "abc.com";// System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).HostName.ToLower().Replace(machinename + ".", "");
            _AppSettings = ConfigurationManager.GetSection("domain/" + hostname) as System.Collections.Specialized.NameValueCollection;
        }
    }
}

Whenever you 'see' something in the GUI (SSMS) and you're like "that's what I need", you can always run Sql Profiler to fish for the query that was used.

Run Sql Profiler. Attach it to your database of course.

Then right click in the GUI (in SSMS) and click "Refresh".
And then go see what Profiler "catches".

I got the below when I was in MyDatabase / Security / Users and clicked "refresh" on the "Users".

Again, I didn't come up with the WHERE clause and the LEFT OUTER JOIN, it was a part of the SSMS query. And this query is something that somebody at Microsoft has written (you know, the peeps who know the product inside and out, aka, the experts), so they are familiar with all the weird "flags" in the database.

But the SSMS/GUI -> Sql Profiler tricks works in many scenarios.

SELECT
u.name AS [Name],
'Server[@Name=' + quotename(CAST(
        serverproperty(N'Servername')
       AS sysname),'''') + ']' + '/Database[@Name=' + quotename(db_name(),'''') + ']' + '/User[@Name=' + quotename(u.name,'''') + ']' AS [Urn],
u.create_date AS [CreateDate],
u.principal_id AS [ID],
CAST(CASE dp.state WHEN N'G' THEN 1 WHEN 'W' THEN 1 ELSE 0 END AS bit) AS [HasDBAccess]
FROM
sys.database_principals AS u
LEFT OUTER JOIN sys.database_permissions AS dp ON dp.grantee_principal_id = u.principal_id and dp.type = 'CO'
WHERE
(u.type in ('U', 'S', 'G', 'C', 'K' ,'E', 'X'))
ORDER BY
[Name] ASC

Turning my comment into an answer:

In case anyone did what I did, which was start by putting all the build files in the source directory:

cd src
cmake .

cmake will put a bunch of build files and cache files (CMakeCache.txt, CMakeFiles, cmake_install.cmake, etc) in the src dir.

To change to an out of source build, I had to remove all of those files. Then I could do what @Angew recommended in his answer:

mkdir -p src/build
cd src/build
cmake ..

I am late to this question, but I think the best way to handle JDK versions on MacOS is by using the script described at: http://www.jayway.com/2014/01/15/how-to-switch-jdk-version-on-mac-os-x-maverick/

You can create your own JsonDeserializer and annotate that property with @JsonDeserialize(as = DefaultZero.class)

For example: To configure BigDecimal to default to ZERO:

public static class DefaultZero extends JsonDeserializer<BigDecimal> {
    private final JsonDeserializer<BigDecimal> delegate;

    public DefaultZero(JsonDeserializer<BigDecimal> delegate) {
        this.delegate = delegate;
    }

    @Override
    public BigDecimal deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
        return jsonParser.getDecimalValue();
    }

    @Override
    public BigDecimal getNullValue(DeserializationContext ctxt) throws JsonMappingException {
        return BigDecimal.ZERO;
    }
}

And usage:

class Sth {

   @JsonDeserialize(as = DefaultZero.class)
   BigDecimal property;
 }

After spending few hours, adding the following css class fixed my issue.

Work with Bootstrap 3.0.*

.tnav .navbar .container { height: 28px; }

Work with Bootstrap 3.3.4

.navbar-nav > li > a, .navbar-brand {
    padding-top:4px !important; 
    padding-bottom:0 !important;
    height: 28px;
}
.navbar {min-height:28px !important;}

It would be helpful if you provided more information - e.g. what OS your using, what you want to accomplish, etc. But, generally speaking cURL is a very powerful command-line tool I frequently use (in linux) for imitating HTML requests:

For example:

curl --data "post1=value1&post2=value2&etc=valetc" http://host/resource

OR, for a RESTful API:

curl -X POST -d @file http://host/resource

You can check out more information here-> http://curl.haxx.se/

EDITs:

OK. So basically you're looking to stress test your REST server? Then cURL really isn't helpful unless you want to write your own load-testing program, even then sockets would be the way to go. I would suggest you check out Gatling. The Gatling documentation explains how to set up the tool, and from there your can run all kinds of GET, POST, PUT and DELETE requests.

Unfortunately, short of writing your own program - i.e. spawning a whole bunch of threads and inundating your REST server with different types of requests - you really have to rely on a stress/load-testing toolkit. Just using a REST client to send requests isn't going to put much stress on your server.

More EDITs

So in order to simulate a post request on a socket, you basically have to build the initial socket connection with the server. I am not a C# guy, so I can't tell you exactly how to do that; I'm sure there are 1001 C# socket tutorials on the web. With most RESTful APIs you usually need to provide a URI to tell the server what to do. For example, let's say your API manages a library, and you are using a POST request to tell the server to update information about a book with an id of '34'. Your URI might be

http://localhost/library/book/34

Therefore, you should open a connection to localhost on port 80 (or 8080, or whatever port your server is on), and pass along an HTML request header. Going with the library example above, your request header might look as follows:

POST library/book/34 HTTP/1.0\r\n
X-Requested-With: XMLHttpRequest\r\n
Content-Type: text/html\r\n
Referer: localhost\r\n
Content-length: 36\r\n\r\n
title=Learning+REST&author=Some+Name

From here, the server should shoot back a response header, followed by whatever the API is programed to tell the client - usually something to say the POST succeeded or failed. To stress test your API, you should essentially do this over and over again by creating a threaded process.

Also, if you are posting JSON data, you will have to alter your header and content accordingly. Frankly, if you are looking to do this quick and clean, I would suggest using python (or perl) which has several libraries for creating POST, PUT, GET and DELETE request, as well as POSTing and PUTing JSON data. Otherwise, you might end up doing more programming than stress testing. Hope this helps!

Does the class org.apache.maven.shared.filtering.MavenFilteringException exist in file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar?

The error message suggests that it doesn't. Maybe the JAR was corrupted somehow.

I'm also wondering where the version 1.0-beta-2 comes from; I have 1.0 on my disk. Try version 2.3 of the WAR plugin.

Most of the other answers point to eager loading, but I found another solution.

In my case I had an EF object InventoryItem with a collection of InvActivity child objects.

class InventoryItem {
...
   // EF code first declaration of a cross table relationship
   public virtual List<InvActivity> ItemsActivity { get; set; }

   public GetLatestActivity()
   {
       return ItemActivity?.OrderByDescending(x => x.DateEntered).SingleOrDefault();
   }
...
}

And since I was pulling from the child object collection instead of a context query (with IQueryable), the Include() function was not available to implement eager loading. So instead my solution was to create a context from where I utilized GetLatestActivity() and attach() the returned object:

using (DBContext ctx = new DBContext())
{
    var latestAct = _item.GetLatestActivity();

    // attach the Entity object back to a usable database context
    ctx.InventoryActivity.Attach(latestAct);

    // your code that would make use of the latestAct's lazy loading
    // ie   latestAct.lazyLoadedChild.name = "foo";
}

Thus you aren't stuck with eager loading.

I ran into similar issues whose cause and solution turned out both to be rather simple:

Main Cause: Did not import the proper cert using keytool

NOTE: Only import root CA (or your own self-signed) certificates

NOTE: don't import an intermediate, non certificate chain root cert

Solution Example for imap.gmail.com

1. Determine the root CA cert:

   openssl s_client -showcerts -connect imap.gmail.com:993
   

   in this case we find the root CA is Equifax Secure Certificate Authority

2. Download root CA cert.
3. Verify downloaded cert has proper SHA-1 and/or MD5 fingerprints by comparing with info found here

4. Import cert for javax.net.ssl.trustStore:

   keytool -import -alias gmail_imap -file Equifax_Secure_Certificate_Authority.pem
   

5. Run your java code

In Android Studio, click on the app folder, then the src folder, and then the main folder. Inside the main folder you can add the assets folder.

NodeJS answer:

In case you wanted to do it with NodeJS: make a GET to JSON endpoint with Authorization header and get a Promise back:

First

npm install --save request request-promise

(see on npm) and then in your .js file:

var requestPromise = require('request-promise');

var user = 'user';
var password = 'password';

var base64encodedData = Buffer.from(user + ':' + password).toString('base64');

requestPromise.get({
  uri: 'https://example.org/whatever',
  headers: {
    'Authorization': 'Basic ' + base64encodedData
  },
  json: true
})
.then(function ok(jsonData) {
  console.dir(jsonData);
})
.catch(function fail(error) {
  // handle error
});

Change:

using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))

To:

 using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\Wow6432Node\MySQL AB\MySQL Connector\Net"))

alternatively you can perform a fast export without using Office dll, as Excel can parse csv files without problems.

Doing something like this (for less than 65.536 rows with titles):

  Try

            If (p_oGrid.RowCount = 0) Then
                MsgBox("No data", MsgBoxStyle.Information, "App")
                Exit Sub
            End If

            Cursor.Current = Cursors.WaitCursor

            Dim sText As New System.Text.StringBuilder
            Dim sTmp As String
            Dim aVisibleData As New List(Of String)

            For iAuxRow As Integer = 0 To p_oGrid.Columns.Count - 1
                If p_oGrid.Columns(iAuxRow).Visible Then
                    aVisibleData.Add(p_oGrid.Columns(iAuxRow).Name)
                    sText.Append(p_oGrid.Columns(iAuxRow).HeaderText.ToUpper)
                    sText.Append(";")
                End If
            Next
            sText.AppendLine()

            For iAuxRow As Integer = 0 To p_oGrid.RowCount - 1
                Dim oRow As DataGridViewRow = p_oGrid.Rows(iAuxRow)
                For Each sCol As String In aVisibleData
                    Dim sVal As String
                    sVal = oRow.Cells(sCol).Value.ToString()
                    sText.Append(sVal.Replace(";", ",").Replace(vbCrLf, " ; "))
                    sText.Append(";")
                Next
                sText.AppendLine()
            Next

            sTmp = IO.Path.GetTempFileName & ".csv"
            IO.File.WriteAllText(sTmp, sText.ToString, System.Text.Encoding.UTF8)
            sText = Nothing

            Process.Start(sTmp)

        Catch ex As Exception
            process_error(ex)
        Finally
            Cursor.Current = Cursors.Default
        End Try

A reference is really a pointer with enough sugar to make it taste nice... ;)

But it also uses a different syntax to pointers, which makes it a bit easier to use references than pointers. Because of this, we don't need & when calling the function that takes the pointer - the compiler deals with that for you. And you don't need * to get the content of a reference.

To call a reference an alias is a pretty accurate description - it is "another name for the same thing". So when a is passed as a reference, we're really passing a, not a copy of a - it is done (internally) by passing the address of a, but you don't need to worry about how that works [unless you are writing your own compiler, but then there are lots of other fun things you need to know when writing your own compiler, that you don't need to worry about when you are just programming].

Note that references work the same way for int or a class type.

It seemed that a lot of dependencies were incorrect.

Download the whole POM here

A good place to look for the correct dependencies is the Maven Repository website.

The main difference between name() and toString() is that name() is a final method, so it cannot be overridden. The toString() method returns the same value that name() does by default, but toString() can be overridden by subclasses of Enum.

Therefore, if you need the name of the field itself, use name(). If you need a string representation of the value of the field, use toString().

For instance:

public enum WeekDay {
    MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY;

    public String toString() {
        return name().charAt(0) + name().substring(1).toLowerCase();
    }
}

In this example, WeekDay.MONDAY.name() returns "MONDAY", and WeekDay.MONDAY.toString() returns "Monday".

WeekDay.valueOf(WeekDay.MONDAY.name()) returns WeekDay.MONDAY, but WeekDay.valueOf(WeekDay.MONDAY.toString()) throws an IllegalArgumentException.

?hange USB connection mode from MTP to Camera (for Nexus 7) or, possibly, to Mass Storage or something else (for other devices). This option is usually under Settings -> Storage. Then connect the device again, you'll get the authorization dialog.

MTP has been known to interfere with USB debugging -- these two did not work together at all on majority of older devices. Nexus 7 and many newer devices do allow both to work alongside, but this particular issue suggests it's not all that smooth yet.

Bonus -- checklist for when adb is not behaving well:

• adb kill-server followed by adb start-server
• (on device) Settings -> Developer Options -> USB Debugging -- switch off and on
• [Windows] Make sure you have the proper driver (your best bet is Universal Adb Driver by Koushik Dutta -- will handle any device)
• [Windows] Try turning off all fancy on-the-fly anti-malware scanners/firewalls
• [Linux] Make sure you have the proper UDEV rule in /etc/udev/rules.d/51-android.rules (again, universal solution: https://github.com/snowdream/51-android)
• [Linux] Make sure everything under ~/.android is owned by you, not root (and upvote this answer)
• restart device (yes, surprisingly, this is a valid measure, too)
• (Obviously) replug cable, try different cable, different port, remove any extender cables

In Linux i want to add a daemon that cannot be stopped and which monitors filesystem changes. If any changes would be detected it should write the path to the console where it was started + a newline.

Daemons work in the background and (usually...) don't belong to a TTY that's why you can't use stdout/stderr in the way you probably want. Usually a syslog daemon (syslogd) is used for logging messages to files (debug, error,...).

Besides that, there are a few required steps to daemonize a process.

If I remember correctly these steps are:

• fork off the parent process & let it terminate if forking was successful. -> Because the parent process has terminated, the child process now runs in the background.
• setsid - Create a new session. The calling process becomes the leader of the new session and the process group leader of the new process group. The process is now detached from its controlling terminal (CTTY).
• Catch signals - Ignore and/or handle signals.
• fork again & let the parent process terminate to ensure that you get rid of the session leading process. (Only session leaders may get a TTY again.)
• chdir - Change the working directory of the daemon.
• umask - Change the file mode mask according to the needs of the daemon.
• close - Close all open file descriptors that may be inherited from the parent process.

To give you a starting point: Look at this skeleton code that shows the basic steps. This code can now also be forked on GitHub: Basic skeleton of a linux daemon

        break;
    }

    syslog (LOG_NOTICE, "First daemon terminated.");
    closelog();

    return EXIT_SUCCESS;
}

• Compile the code: gcc -o firstdaemon daemonize.c
• Start the daemon: ./firstdaemon

• Check if everything is working properly: ps -xj | grep firstdaemon

• The output should be similar to this one:

+------+------+------+------+-----+-------+------+------+------+-----+
| PPID | PID  | PGID | SID  | TTY | TPGID | STAT | UID  | TIME | CMD |
+------+------+------+------+-----+-------+------+------+------+-----+
|    1 | 3387 | 3386 | 3386 | ?   |    -1 | S    | 1000 | 0:00 | ./  |
+------+------+------+------+-----+-------+------+------+------+-----+

What you should see here is:

• The daemon has no controlling terminal (TTY = ?)
• The parent process ID (PPID) is 1 (The init process)
• The PID != SID which means that our process is NOT the session leader
  (because of the second fork())
• Because PID != SID our process can't take control of a TTY again

Reading the syslog:

• Locate your syslog file. Mine is here: /var/log/syslog

• Do a: grep firstdaemon /var/log/syslog

• The output should be similar to this one:

  firstdaemon[3387]: First daemon started.
  firstdaemon[3387]: First daemon terminated.

A note: In reality you would also want to implement a signal handler and set up the logging properly (Files, log levels...).

I've been there too and searched everywhere how /usr/libexec/java_home works but I couldn't find any information on how it determines the available Java Virtual Machines it lists.

I've experimented a bit and I think it simply executes a ls /Library/Java/JavaVirtualMachines and then inspects the ./<version>/Contents/Info.plist of all runtimes it finds there.

It then sorts them descending by the key JVMVersion contained in the Info.plist and by default it uses the first entry as its default JVM.

I think the only thing we might do is to change the plist: sudo vi /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Info.plist and then modify the JVMVersion from 1.8.0 to something else that makes it sort it to the bottom instead of the top, like !1.8.0.

Something like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    ...
    <dict>
            ...
            <key>JVMVersion</key>
            <string>!1.8.0</string>   <!-- changed from '1.8.0' to '!1.8.0' -->`

and then it magically disappears from the top of the list:

/usr/libexec/java_home -verbose
Matching Java Virtual Machines (3):
    1.7.0_45, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home
    1.7.0_09, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home
    !1.8.0, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home

Now you will need to logout/login and then:

java -version
java version "1.7.0_45"

:-)

Of course I have no idea if something else breaks now or if the 1.8.0-ea version of java still works correctly.

You probably should not do any of this but instead simply deinstall 1.8.0.

However so far this has worked for me.

My issue resolve via following Steps

1. File->Import (android-sdk\extras\android\support\v7\appcompat)

2. Right Click Project-> properties->Android. In the section library "Add" and choose library appcompat that's include in step 1

3. Delete all files from project's libs directory

4. add following file to project's libs directory <SDK-PATH>\extras\android\support\v13android-support-v13.jar

   Restart Eclipse if required. That's it. Your problem should be disappeared.

I would change the query in the following ways:

1. Do the aggregation in subqueries. This can take advantage of more information about the table for optimizing the group by.
2. Combine the second and third subqueries. They are aggregating on the same column. This requires using a left outer join to ensure that all data is available.
3. By using count(<fieldname>) you can eliminate the comparisons to is null. This is important for the second and third calculated values.
4. To combine the second and third queries, it needs to count an id from the mde table. These use mde.mdeid.

The following version follows your example by using union all:

SELECT CAST(Detail.ReceiptDate AS DATE) AS "Date",
       SUM(TOTALMAILED) as TotalMailed,
       SUM(TOTALUNDELINOTICESRECEIVED) as TOTALUNDELINOTICESRECEIVED,
       SUM(TRACEUNDELNOTICESRECEIVED) as TRACEUNDELNOTICESRECEIVED
FROM ((select SentDate AS "ReceiptDate", COUNT(*) as TotalMailed,
              NULL as TOTALUNDELINOTICESRECEIVED, NULL as TRACEUNDELNOTICESRECEIVED
       from MailDataExtract
       where SentDate is not null
       group by SentDate
      ) union all
      (select MDE.ReturnMailDate AS ReceiptDate, 0,
              COUNT(distinct mde.mdeid) as TOTALUNDELINOTICESRECEIVED,
              SUM(case when sd.ReturnMailTypeId = 1 then 1 else 0 end) as TRACEUNDELNOTICESRECEIVED
       from MailDataExtract MDE left outer join
            DTSharedData.dbo.ScanData SD
            ON SD.ScanDataID = MDE.ReturnScanDataID
       group by MDE.ReturnMailDate;
      )
     ) detail
GROUP BY CAST(Detail.ReceiptDate AS DATE)
ORDER BY 1;

The following does something similar using full outer join:

SELECT coalesce(sd.ReceiptDate, mde.ReceiptDate) AS "Date",
       sd.TotalMailed, mde.TOTALUNDELINOTICESRECEIVED,
       mde.TRACEUNDELNOTICESRECEIVED
FROM (select cast(SentDate as date) AS "ReceiptDate", COUNT(*) as TotalMailed
      from MailDataExtract
      where SentDate is not null
      group by cast(SentDate as date)
     ) sd full outer join
    (select cast(MDE.ReturnMailDate as date) AS ReceiptDate,
            COUNT(distinct mde.mdeID) as TOTALUNDELINOTICESRECEIVED,
            SUM(case when sd.ReturnMailTypeId = 1 then 1 else 0 end) as TRACEUNDELNOTICESRECEIVED
     from MailDataExtract MDE left outer join
          DTSharedData.dbo.ScanData SD
          ON SD.ScanDataID = MDE.ReturnScanDataID
     group by cast(MDE.ReturnMailDate as date)
    ) mde
    on sd.ReceiptDate = mde.ReceiptDate
ORDER BY 1;

At current, Android doesn't support Java 7, only Java 6. New features in Java 7 such as the diamond syntax are therefore not currently supported. Finding sources to support this isn't easy, but I could find that the Dalvic engine is built upon a subset of Apache Harmony which only ever supported Java up to version 6. And if you check the system requirements for developing Android apps it also states that at least JDK 6 is needed (though this of course isn't real proof, just an indication). And this says pretty much the same as I have. If I find anything more substancial, I'll add it.

Edit: It seems Java 7 support has been added since I originally wrote this answer; check the answer by Sergii Pechenizkyi.

Are you after something like this:

 <html>
 <head>
    <title>Z Test</title>
 </head>
 <body>

<div id="img_home"></div>

<button onclick="addimage()" type="button">Add an image</button>

<script>
function addimage() {
    var img = new Image();
    img.src = "https://www.google.com/images/srpr/logo4w.png"
    img_home.appendChild(img);
}
</script>
</body>

You do not define a binding in your service's config, so you are getting the default values for wsHttpBinding, and the default value for securityMode\transport for that binding is Message.

Try copying your binding configuration from the client's config to your service config and assign that binding to the endpoint via the bindingConfiguration attribute:

<bindings>
  <wsHttpBinding>
    <binding name="ota2010AEndpoint" 
             .......>
      <readerQuotas maxDepth="32" ... />
        <reliableSession ordered="true" .... />
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
                       realm="" />
            <message clientCredentialType="Windows" negotiateServiceCredential="true"
                     establishSecurityContext="true" />
          </security>
    </binding>
  </wsHttpBinding>
</bindings>    

(Snipped parts of the config to save space in the answer).

<service name="Synxis" behaviorConfiguration="SynxisWCF">
    <endpoint address="" name="wsHttpEndpoint" 
              binding="wsHttpBinding" 
              bindingConfiguration="ota2010AEndpoint"
              contract="Synxis" />

This will then assign your defined binding (with Transport security) to the endpoint.

I think you can use display: inline-block on the element you want to center and set text-align: center; on its parent. This definitely center the div on all screen sizes.

Here you can see a fiddle: http://jsfiddle.net/PwC4T/2/ I add the code here for completeness.

HTML

<div id="container">
    <div id="main">
        <div id="somebackground">
            Hi
        </div>
    </div>
</div>

CSS

#container
{
    text-align: center;
}
#main
{
    display: inline-block;
}
#somebackground
{
    text-align: left;
    background-color: red;
}

For vertical centering, I "dropped" support for some older browsers in favour of display: table;, which absolutely reduce code, see this fiddle: http://jsfiddle.net/jFAjY/1/

Here is the code (again) for completeness:

HTML

<body>
    <div id="table-container">
        <div id="container">
            <div id="main">
                <div id="somebackground">
                    Hi
                </div>
            </div>
        </div>
    </div>
</body>

CSS

body, html
{
    height: 100%;
}
#table-container
{
    display:    table;
    text-align: center;
    width:      100%;
    height:     100%;
}
#container
{
    display:        table-cell;
    vertical-align: middle;
}
#main
{
    display: inline-block;
}
#somebackground
{
    text-align:       left;
    background-color: red;
}

The advantage of this approach? You don't have to deal with any percantage, it also handles correctly the <video> tag (html5), which has two different sizes (one during load, one after load, you can't fetch the tag size 'till video is loaded).

The downside is that it drops support for some older browser (I think IE8 won't handle this correctly)

try jquery,

  <div>
        <a href="#" class="majorpoints" onclick="majorpointsexpand(" + $('.majorpointslegend').html() + ")"/>
        <legend class="majorpointslegend">Expand</legend>
        <div id="data" style="display:none" >
            <ul>
                <li></li>
                <li></li>
            </ul>
        </div>
    </div>


function majorpointsexpand(expand)
    {
        if (expand == "Expand")
            {
                $('#data').css("display","inherit");
                $(".majorpointslegend").html("Collapse");
            }
        else
            {
                $('#data').css("display","none");
                $(".majorpointslegend").html("Expand");
            }
    }

You can implement this way

$resource('http://localhost\\:3000/realmen/:entryId', {entryId: '@entryId'}, {
        UPDATE: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId' },
        ACTION: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId/action' }
    })

RealMen.query() //GET  /realmen/
RealMen.save({entryId: 1},{post data}) // POST /realmen/1
RealMen.delete({entryId: 1}) //DELETE /realmen/1

//any optional method
RealMen.UPDATE({entryId:1}, {post data}) // PUT /realmen/1

//query string
RealMen.query({name:'john'}) //GET /realmen?name=john

Is your SQL Server in 'mixed mode authentication' ? This is necessary to login with a SQL server account instead of a Windows login.

You can verify this by checking the properties of the server and then SECURITY, it should be in 'SQL Server and Windows Authentication Mode'

This problem occurs if the user tries to log in with credentials that cannot be validated. This problem can occur in the following scenarios:

Scenario 1: The login may be a SQL Server login but the server only accepts Windows Authentication.

Scenario 2: You are trying to connect by using SQL Server Authentication but the login used does not exist on SQL Server.

Scenario 3: The login may use Windows Authentication but the login is an unrecognized Windows principal. An unrecognized Windows principal means that Windows can't verify the login. This might be because the Windows login is from an untrusted domain.

It's also possible the user put in incorrect information.

I see there is a VBA solution and a non-VBA solution, which both are really good. I wanted to propose my Javascript solution.

There is an Excel add-in called Funfun that allows you to use javascript, HTML and css in Excel. It has an online editor with an embedded spreadsheet where you can build your chart.

I have written this code for you with Chart.js:

https://www.funfun.io/1/#/edit/5a61ed15404f66229bda3f44

To create this chart, I entered my data on the spreadsheet and read it with a json file, it is the short file.

I make sure to put it in the right format, in script.js, so I can add it to my chart:

var data = [];
var color = [];
var label = [];

for (var i = 1; i < $internal.data.length; i++)
{
    label.push($internal.data[i][0]);
    data.push([$internal.data[i][1], $internal.data[i][2]]);
    color.push($internal.data[i][3]);
}

I then create the scatter chart with each dot having his designated color and position:

 var dataset = [];
  for (var i = 0; i < data.length; i++) {   
    dataset.push({
      data: [{
        x: data[i][0],
        y: data[i][1] 
      }],
      pointBackgroundColor: color[i],
      pointStyle: "cercle",
      radius: 6  
    });
  }

After I've created my scatter chart I can upload it in Excel by pasting the URL in the funfun Excel add-in. Here is how it looks like with my example:

Once this is done You can change the color or the position of a dot instantly, in Excel, by changing the values in the spreadsheet.

If you want to add extra dots in the charts you just need to modify the radius of data in the short json file.

Hope this Javascript solution helps !

In Python, you can use urllib2 (http://docs.python.org/2/library/urllib2.html) to do all of that work for you.

Simply enough:

import urllib2
f =  urllib2.urlopen(url)
print f.read() 

Will print the received HTTP response.

To pass GET/POST parameters the urllib.urlencode() function can be used. For more information, you can refer to the Official Urllib2 Tutorial

To find which processes are creating threads try:

ps huH

I normally redirect output to a file and analysis the file offline (is thread count for each process is as expected or not)

In addition to install the build tools and restart the update manager I also had to restart Eclipse to make this work.

I'm new to shell scripting too, but I had this same issue. Make sure at the end of your script you have a blank line. Otherwise it won't work.

Your check should be:

if (Attachment != null  && Attachment.Length > 0)

First check if the Attachment is null and then lenght, since you are using && that will cause short-circut evaluation

&& Operator (C# Reference)

The conditional-AND operator (&&) performs a logical-AND of its bool operands, but only evaluates its second operand if necessary.

Previously you had the condition like: (Attachment.Length > 0 && Attachment != null), since the first condition is accessing the property Length and if Attachment is null, you end up with the exception, With the modified condition (Attachment != null && Attachment.Length > 0), it will check for null first and only moves further if Attachment is not null.

If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.

To trigger an event after ng-repeat has rendered try this directive:

var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
    restrict: 'A',
    link: function (scope, element, attr) {
        if (scope.$last === true) {
            $timeout(function () {
                scope.$emit('ngRepeatFinished');
            });
        }
    }
}
});

Complete example in angular: http://jsfiddle.net/ADukg/6880/

I got the directive from here: Use AngularJS just for routing purposes

Solution - Install any package by marking below hosts trusted

• pypi.python.org
• pypi.org
• files.pythonhosted.org

Temporary solution

pip install --trusted-host pypi.python.org --trusted-host pypi.org --trusted-host files.pythonhosted.org {package name}

Permanent solution - Update your PIP(problem with version 9.0.1) to latest.

pip install --trusted-host pypi.python.org --trusted-host pypi.org --trusted-host files.pythonhosted.org pytest-xdist

python -m pip install --trusted-host pypi.python.org --trusted-host pypi.org --trusted-host files.pythonhosted.org --upgrade pip

$('input[type="submit"]').click(function(){
$(this).css('color','red');
});

Use class, Demo:- http://jsfiddle.net/BX6Df/

   $('input[type="submit"]').click(function(){
          $(this).addClass('red');
});

if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/

$('input[type="submit"]').click(function(){
  $(this).toggleClass('red');
});


.red
{
    background-color:red;
}

Updated answer for your comment.

http://jsfiddle.net/H2Xhw/

$('input[type="submit"]').click(function(){
    $('input[type="submit"].red').removeClass('red')
        $(this).addClass('red');
});

Don't over complicate.

  document.addEventListener('keydown', logKey);
    function logKey(e) {

          if (`${e.code}` == "ArrowLeft") {
        //code here
      }
          if (`${e.code}` == "ArrowDown") {
        //code here
      }
          if (`${e.code}` == "ArrowUp") {

You can use java.util.concurrent.TimeUnit library which internally uses Thread.sleep. The syntax should look like this :

@Test
public void testExipres(){
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExipration("foo", 1000);

    TimeUnit.MINUTES.sleep(2);

    assertNull(sco.getIfNotExipred("foo"));
}

This library provides more clear interpretation for time unit. You can use 'HOURS'/'MINUTES'/'SECONDS'.

Turns out that I actually had the Java 7 JRE installed, not the JDK. The correct download link is here. After installing it, jdk1.7.0jdk appears in the JavaVirtualMachines directory.

In the thread dump you can find the Line Number as below.

ssize_t is not included in the standard and isn't portable. size_t should be used when handling the size of objects (there's ptrdiff_t too, for pointer differences).

    Arrays.sort(arr);
    int max=0,mode=0,count=0;
    for(int i=0;i<N;i=i+count) {
        count = 1;
        for(int j=i+1; j<N; j++) {
            if(arr[i] == arr[j])
                count++;
        }
        if(count>max) {
            max=count;
            mode = arr[i];
        }
    }

you should use position: relative; for one iframe and position:absolute; for the second;

Example: for first iframe use:

<div id="contentframe" style="position:relative; top: 100px; left: 50px;">

for second iframe use:

<div id="contentframe" style="position:absolute; top: 0px; left: 690px;">

Similar to Mike's and clacke's answers, here is the python one-liner (using python >= 2.5) to get the build version from a pom.xml file that gets around the fact that pom.xml files don't normally have a dtd or default namespace, so don't appear well-formed to libxml:

python -c "import xml.etree.ElementTree as ET; \
  print(ET.parse(open('pom.xml')).getroot().find('\
  {http://maven.apache.org/POM/4.0.0}version').text)"

Tested on Mac and Linux, and doesn't require any extra packages to be installed.

In addition to @Boaz's and @vegemite4me's answers....

By implementing ImplicitNamingStrategy you may create rules for automatically naming the constraints. Note you add your naming strategy to the metadataBuilder during Hibernate's initialization:

metadataBuilder.applyImplicitNamingStrategy(new MyImplicitNamingStrategy());

It works for @UniqueConstraint, but not for @Column(unique = true), which always generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).

There is a bug report to solve this issue, so if you can, please vote there to have this implemented. Here: https://hibernate.atlassian.net/browse/HHH-11586

Thanks.

It got deprecated in version 4.3-alpha1 which you use because of the LATEST version specification. If you take a look at the javadoc of the class, it tells you what to use instead: HttpClientBuilder.

In the latest stable version (4.2.3) the DefaultHttpClient is not deprecated yet.

If your constructor is similar to this one:

public Example(String example) {
    if (example == null) {
        throw new NullPointerException();
    }
    //do fun things with valid example here
}

Then, when you run this JUnit test you will get a green bar:

@Test(expected = NullPointerException.class)
public void constructorShouldThrowNullPointerException() {
    Example example = new Example(null);
}

I had the same issue, and the solution is very simple, just change to git bash from cmd or other windows command line tools. Windows sometimes does not work well with git npm dependencies.

Other possible solution:

tv.setText(Integer.toString(a1));  // where a1 - int value

use Procedure

Create proc MyView as begin SELECT TOP 99999999999999 Column1, Column2 FROM dbo.Table Order by Column1 end

execute procedure

exec MyView

The most important thing to know about async and await is that await doesn't wait for the associated call to complete. What await does is to return the result of the operation immediately and synchronously if the operation has already completed or, if it hasn't, to schedule a continuation to execute the remainder of the async method and then to return control to the caller. When the asynchronous operation completes, the scheduled completion will then execute.

The answer to the specific question in your question's title is to block on an async method's return value (which should be of type Task or Task<T>) by calling an appropriate Wait method:

public static async Task<Foo> GetFooAsync()
{
    // Start asynchronous operation(s) and return associated task.
    ...
}

public static Foo CallGetFooAsyncAndWaitOnResult()
{
    var task = GetFooAsync();
    task.Wait(); // Blocks current thread until GetFooAsync task completes
                 // For pedagogical use only: in general, don't do this!
    var result = task.Result;
    return result;
}

In this code snippet, CallGetFooAsyncAndWaitOnResult is a synchronous wrapper around asynchronous method GetFooAsync. However, this pattern is to be avoided for the most part since it will block a whole thread pool thread for the duration of the asynchronous operation. This an inefficient use of the various asynchronous mechanisms exposed by APIs that go to great efforts to provide them.

The answer at "await" doesn't wait for the completion of call has several, more detailed, explanations of these keywords.

Meanwhile, @Stephen Cleary's guidance about async void holds. Other nice explanations for why can be found at http://www.tonicodes.net/blog/why-you-should-almost-never-write-void-asynchronous-methods/ and https://jaylee.org/archive/2012/07/08/c-sharp-async-tips-and-tricks-part-2-async-void.html

[Test double types]

Mock vs Spy

Mock is a bare double object. This object has the same methods signatures but realisation is empty and return default value - 0 and null

Spy is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it

class A {
    String foo1() {
        foo2();
        return "RealString_1";
    }

    String foo2() {
        return "RealString_2";
    }

    void foo3() { foo4(); }

    void foo4() { }
}

@Test
public void testMockA() {
    //given
    A mockA = Mockito.mock(A.class);
    Mockito.when(mockA.foo1()).thenReturn("MockedString");

    //when
    String result1 = mockA.foo1();
    String result2 = mockA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals(null, result2);

    //Case 2
    //when
    mockA.foo3();

    //then
    verify(mockA).foo3();
    verify(mockA, never()).foo4();
}

@Test
public void testSpyA() {
    //given
    A spyA = Mockito.spy(new A());

    Mockito.when(spyA.foo1()).thenReturn("MockedString");

    //when
    String result1 = spyA.foo1();
    String result2 = spyA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals("RealString_2", result2);

    //Case 2
    //when
    spyA.foo3();

    //then
    verify(spyA).foo3();
    verify(spyA).foo4();
}

For example :

In MainActivity :

Intent intent = new Intent(this, OtherActivity.class);
intent.putExtra(OtherActivity.KEY_EXTRA, yourDataObject);
startActivity(intent);

In OtherActivity :

public static final String KEY_EXTRA = "com.example.yourapp.KEY_BOOK";

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  String yourDataObject = null;

  if (getIntent().hasExtra(KEY_EXTRA)) {
      yourDataObject = getIntent().getStringExtra(KEY_EXTRA);
  } else {
      throw new IllegalArgumentException("Activity cannot find  extras " + KEY_EXTRA);
  }
  // do stuff
}

but I don't see a problem on my browser (Google Chrome)

I was facing the same issue and found here useful steps which saved my time a lot. Hope so below attached image will help you a lot-

Window-> Preferences-> General-> Network Connection

Change Active Provider Native to Manual if problem is not resolved by using the steps mentioned in snapshot. Make sure HTTP/HTTPS should be checked and if any IP is required for your proxy settings then you should provide proxy IP in host and port number as well.

If you use jquery.validate.js and jquery.validate.unobtrusive.js for validating on client side, you should remember that you have to register any validation attribute of any DOM element on your request. Therefor you can use this code:

$.validator.unobtrusive.parse('your main element on layout');

to register all validation attributes. You can call this method on (for example) : $(document).ajaxSuccess() or $(document).ready() to register all of them and your validation can be occurred successfully instead of registering all js files on cshtml files.

Timer

As mentioned on the javadocs you are better off using a ScheduledThreadPoolExecutor.

ScheduledThreadPoolExecutor

Use this class when your use case requires multiple worker threads and the sleep interval is small. How small ? Well, I'd say about 15 minutes. The AlarmManager starts schedule intervals at this time and it seems to suggest that for smaller sleep intervals this class can be used. I do not have data to back the last statement. It is a hunch.

Service

Your service can be closed any time by the VM. Do not use services for recurring tasks. A recurring task can start a service, which is another matter entirely.

BroadcastReciever with AlarmManager

For longer sleep intervals (>15 minutes), this is the way to go. AlarmManager already has constants ( AlarmManager.INTERVAL_DAY ) suggesting that it can trigger tasks several days after it has initially been scheduled. It can also wake up the CPU to run your code.

You should use one of those solutions based on your timing and worker thread needs.

you need to add Content-Disposition header, smth like this (although I used mod-python here, but principle should be the same):

request.headers_out['Content-Disposition'] = 'attachment; filename=%s' % myfname

We were using an incompatible version of Ruby inside of Terminal (Mac), but once we used RVM to switch to Ruby 2.1.2, Cocoapods came back.

Try to change Java compiler settings in Properties in Eclipse-

Goto: Preferences->Java->Compiler->Compiler Compliance Level-> 1.7 Apply Ok

Restart IDE.

Confirm Compiler setting for project- Goto: Project Properties->Java Compiler-> Uncheck(Use Compliance from execution environment 'JavaSE-1.6' on the java Build path.) and select 1.7 from the dropdown. (Ignore if already 1.7)

Restart IDE.

If still the problem persist- Run individual test cases using command in terminal-

mvn -Dtest=<test class name> test

Yes you can! For a simple repository that only publish/retrieve artifacts, you can use nginx.

1. Make sure nginx has http dav module enabled, it should, but nonetheless verify it.

2. Configure nginx http dav module:

   In Windows: d:\servers\nginx\nginx.conf

   location / {
       # maven repository
       dav_methods  PUT DELETE MKCOL COPY MOVE;
       create_full_put_path  on;
       dav_access  user:rw group:rw all:r;
   }
   

   In Linux (Ubuntu): /etc/nginx/sites-available/default

   location / {
           # First attempt to serve request as file, then
           # as directory, then fall back to displaying a 404.
           # try_files $uri $uri/ =404;  # IMPORTANT comment this
           dav_methods  PUT DELETE MKCOL COPY MOVE;
           create_full_put_path  on;
           dav_access  user:rw group:rw all:r;
   }
   

   Don't forget to give permissions to the directory where the repo will be located:

   sudo chmod +777 /var/www/html/repository

3. In your project's pom.xml add the respective configuration:

   Retrieve artifacts:

   <repositories>
       <repository>
           <id>repository</id>
           <url>http://<your.ip.or.hostname>/repository</url>
       </repository>
   </repositories>
   

   Publish artifacts:

   <build>
       <extensions>
           <extension>
               <groupId>org.apache.maven.wagon</groupId>
               <artifactId>wagon-http</artifactId>
               <version>3.2.0</version>
           </extension>
       </extensions>
   </build>
   <distributionManagement>
       <repository>
           <id>repository</id>
           <url>http://<your.ip.or.hostname>/repository</url>
       </repository>
   </distributionManagement>
   

4. To publish artifacts use mvn deploy. To retrieve artifacts, maven will do it automatically.

And there you have it a simple maven repo.

Typically a .sh file is a shell script which you can execute in a terminal. Specifically, the script you mentioned is a bash script, which you can see if you open the file and look in the first line of the file, which is called the shebang or magic line.

I had the same issue. I solved it by using the following steps(Editor: IntelliJ):

1. View -> Tool Windows -> Maven Project. Opens your projects in a sub-window.
2. Click on the arrow next to your project.
3. Click on the lifecycle.
4. Click on clean.

It's to avoid a stack overflow. The Python interpreter limits the depths of recursion to help you avoid infinite recursions, resulting in stack overflows. Try increasing the recursion limit (sys.setrecursionlimit) or re-writing your code without recursion.

From the Python documentation:

sys.getrecursionlimit()

Return the current value of the recursion limit, the maximum depth of the Python interpreter stack. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. It can be set by setrecursionlimit().

Since version 3.4 Apache Common Lang 3 implement the containsAny method.

If you are like me just want to print a sequence within a lambda, without get the return value (list of None).

x = range(3)
from __future__ import print_function           # if not python 3
pra = lambda seq=x: map(print,seq) and None     # pra for 'print all'
pra()
pra('abc')

You can just use the output of is.na to replace directly with subsetting:

bothbeams.data[is.na(bothbeams.data)] <- 0

Or with a reproducible example:

dfr <- data.frame(x=c(1:3,NA),y=c(NA,4:6))
dfr[is.na(dfr)] <- 0
dfr
  x y
1 1 0
2 2 4
3 3 5
4 0 6

However, be careful using this method on a data frame containing factors that also have missing values:

> d <- data.frame(x = c(NA,2,3),y = c("a",NA,"c"))
> d[is.na(d)] <- 0
Warning message:
In `[<-.factor`(`*tmp*`, thisvar, value = 0) :
  invalid factor level, NA generated

It "works":

> d
  x    y
1 0    a
2 2 <NA>
3 3    c

...but you likely will want to specifically alter only the numeric columns in this case, rather than the whole data frame. See, eg, the answer below using dplyr::mutate_if.

The answer with screenshots (put the checkbox as in the second pic, then press OK):

Just use the following sql, you are done:

SELECT replace(CustomerName,' ', '') FROM Customers;

I've run into this need on several Joomla project. The simplest way I've found to address is to add a hidden input field to my template:

<input type="hidden" id="baseurl" name="baseurl" value="<?php echo $this->baseurl; ?>" />

When I need the value in JavaScript:

var baseurl = document.getElementById('baseurl').value;

Not as fancy as using pure JavaScript but simple and gets the job done.

insert into MyTable(field1, field2, id_backup)
    select field1, field2, uniqueId from MyTable where uniqueId = @Id;

PHPMailer handles errors nicely, also a good script to use for sending mail via SMTP...

if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
  echo "Message sent!";
}

The defer attribute is only for external scripts (should only be used if the src attribute is present).

Yes, you can find that under

Tools - > Options - > Projects and Solutions - > Track Active Item in Solution Explorer

It's off by default (as you've noticed), but once it's on, Solution Explorer will expand folders and highlight the current document as you switch between files.

You cannot pass primitives by reference in Java. All variables of object type are actually pointers, of course, but we call them "references", and they are also always passed by value.

In a situation where you really need to pass a primitive by reference, what people will do sometimes is declare the parameter as an array of primitive type, and then pass a single-element array as the argument. So you pass a reference int[1], and in the method, you can change the contents of the array.

Without using Collections in Java:

import java.util.Scanner;

public class SortingaString {
    public static String Sort(String s1)
    {
        char ch[]=s1.toCharArray();         
        String res=" ";
        
        for(int i=0; i<ch.length ; i++)
        {
            for(int j=i+1;j<ch.length; j++)
            {
                if(ch[i]>=ch[j])
                {
                    char m=ch[i];
                    ch[i]=ch[j];
                    ch[j]=m;
                }
            }
            
            res=res+ch[i];
            
        }

        return res;
    }

    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        System.out.println("enter the string");
        
        String s1=sc.next();
        String ans=Sort( s1);
        
        System.out.println("after sorting=="+ans);
    }
}

Output:

enter the string==

after sorting== ginorst

It is an SELinux issue.

You can temporarily issue

su -c "setenforce 0"

on the host to access or else add an SELinux rule by running

chcon -Rt svirt_sandbox_file_t /path/to/volume

I generally store files on the file-system, since that's what its there for, though there are exceptions. For files, the file-system is the most flexible and performant solution (usually).

There are a few problems with storing files on a database - files are generally much larger than your average row - result-sets containing many large files will consume a lot of memory. Also, if you use a storage engine that employs table-locks for writes (ISAM for example), your files table might be locked often depending on the size / rate of files you are storing there.

Regarding security - I usually store the files in a directory that is outside of the document root (not accessible through an http request) and serve them through a script that checks for the proper authorization first.

I would say that the specification does not prevent someone from creating an engine that runs javascript on multiple threads, requiring the code to perform synchronization for accessing shared object state.

I think the single-threaded non-blocking paradigm came out of the need to run javascript in browsers where ui should never block.

Nodejs has followed the browsers' approach.

Rhino engine however, supports running js code in different threads. The executions cannot share context, but they can share scope. For this specific case the documentation states:

..."Rhino guarantees that accesses to properties of JavaScript objects are atomic across threads, but doesn't make any more guarantees for scripts executing in the same scope at the same time.If two scripts use the same scope simultaneously, the scripts are responsible for coordinating any accesses to shared variables."

From reading Rhino documentation I conclude that that it can be possible for someone to write a javascript api that also spawns new javascript threads, but the api would be rhino-specific (e.g. node can only spawn a new process).

I imagine that even for an engine that supports multiple threads in javascript there should be compatibility with scripts that do not consider multi-threading or blocking.

Concearning browsers and nodejs the way I see it is:

• 1. Is all js code executed in a single thread? : Yes.
• 2. Can js code cause other threads to run? : Yes.
• 3. Can these threads mutate js execution context?: No. But they can (directly/indirectly(?)) append to the event queue from which listeners can mutate execution context. But don't be fooled, listeners run atomically on the main thread again.

So, in case of browsers and nodejs (and probably a lot of other engines) javascript is not multithreaded but the engines themselves are.

Update about web-workers:

The presence of web-workers justifies further that javascript can be multi-threaded, in the sense that someone can create code in javascript that will run on a separate thread.

However: web-workers do not curry the problems of traditional threads who can share execution context. Rules 2 and 3 above still apply, but this time the threaded code is created by the user (js code writer) in javascript.

The only thing to consider is the number of spawned threads, from an efficiency (and not concurrency) point of view. See below:

About thread safety:

The Worker interface spawns real OS-level threads, and mindful programmers may be concerned that concurrency can cause “interesting” effects in your code if you aren't careful.

However, since web workers have carefully controlled communication points with other threads, it's actually very hard to cause concurrency problems. There's no access to non-threadsafe components or the DOM. And you have to pass specific data in and out of a thread through serialized objects. So you have to work really hard to cause problems in your code.

P.S.

Besides theory, always be prepared about possible corner cases and bugs described on the accepted answer

MAT, jprofiler,jhat are possible options. since jhat comes with jdk, you can easily launch it to do some basic analysis. check this out

I could fix it using below steps.(GlassFish server3.1.2.2 and eclipse Luna 4.4.1)

1. Help > Eclipse Marketplace > Search GlassFish > you will see GlassFish Tools > Select appropriate one and install it.
2. Restart eclipse
3. Windows > Open Views > Other > Server > Servers > GlassFish 3.1
4. You will need jdk1.7.0 added to Installed JRE. Close the previous window to take effect of new default jdk1.7.0.

Example:

SELECT TRIM('   Sample   ');

Result: 'Sample'

UPDATE TableName SET ColumnName = TRIM(ColumnName)

Checking if v contains the element x:

#include <algorithm>

if(std::find(v.begin(), v.end(), x) != v.end()) {
    /* v contains x */
} else {
    /* v does not contain x */
}

Checking if v contains elements (is non-empty):

if(!v.empty()){
    /* v is non-empty */
} else {
    /* v is empty */
}

foreach(DataRow row in dt.Rows)
{
    string value = row[3].ToString();
}

Call the marker.setIcon('newImage.png')... Look here for the docs.

Are you asking about the actual way to do it? You could just create each div, and a add a mouseover and mouseout listener that would change the icon and back for the markers.

Shouldn't you be providing the credentials for your site, instead of passing the DefaultCredentials?

Something like request.Credentials = new NetworkCredential("UserName", "PassWord");

Also, remove request.UseDefaultCredentials = true; request.PreAuthenticate = true;

An update, several years later

This answer is old, and R has moved on. Tweaking read.table to run a bit faster has precious little benefit. Your options are:

1. Using vroom from the tidyverse package vroom for importing data from csv/tab-delimited files directly into an R tibble. See Hector's answer.

2. Using fread in data.table for importing data from csv/tab-delimited files directly into R. See mnel's answer.

3. Using read_table in readr (on CRAN from April 2015). This works much like fread above. The readme in the link explains the difference between the two functions (readr currently claims to be "1.5-2x slower" than data.table::fread).

4. read.csv.raw from iotools provides a third option for quickly reading CSV files.

5. Trying to store as much data as you can in databases rather than flat files. (As well as being a better permanent storage medium, data is passed to and from R in a binary format, which is faster.) read.csv.sql in the sqldf package, as described in JD Long's answer, imports data into a temporary SQLite database and then reads it into R. See also: the RODBC package, and the reverse depends section of the DBI package page. MonetDB.R gives you a data type that pretends to be a data frame but is really a MonetDB underneath, increasing performance. Import data with its monetdb.read.csv function. dplyr allows you to work directly with data stored in several types of database.

6. Storing data in binary formats can also be useful for improving performance. Use saveRDS/readRDS (see below), the h5 or rhdf5 packages for HDF5 format, or write_fst/read_fst from the fst package.

The original answer

There are a couple of simple things to try, whether you use read.table or scan.

1. Set nrows=the number of records in your data (nmax in scan).

2. Make sure that comment.char="" to turn off interpretation of comments.

3. Explicitly define the classes of each column using colClasses in read.table.

4. Setting multi.line=FALSE may also improve performance in scan.

If none of these thing work, then use one of the profiling packages to determine which lines are slowing things down. Perhaps you can write a cut down version of read.table based on the results.

The other alternative is filtering your data before you read it into R.

Or, if the problem is that you have to read it in regularly, then use these methods to read the data in once, then save the data frame as a binary blob with save saveRDS, then next time you can retrieve it faster with load readRDS.

I'm facing this from file://. I'd like to send queries to two servers from a local HTML file (a testbed).

This particular case should not be any safety concern, but only Safari allows this.

Here is the best discussion I've found of the issue.

Take a look into NSColorWell class reference.

Forget setAttribute(): it's badly broken and doesn't always do what you might expect in old IE (IE <= 8 and compatibility modes in later versions). Use the element's properties instead. This is generally a good idea, not just for this particular case. Replace your code with the following, which will work in all major browsers:

var hiddenInput = document.createElement("input");
hiddenInput.id = "uniqueIdentifier";
hiddenInput.type = "hidden";                     
hiddenInput.value = ID;
hiddenInput.className = "ListItem";

Update

The nasty hack in the second code block in the question is unnecessary, and the code above works fine in all major browsers, including IE 6. See http://www.jsfiddle.net/timdown/aEvUT/. The reason why you get null in your alert() is that when it is called, the new input is not yet in the document, hence the document.getElementById() call cannot find it.

I had the same problem, only need to show shortdate (without the time), moreover it was needed to have multi-language settings, so depends of the language, show dd-mm-yyyy or mm-dd-yyyy.

Finally using DataFormatString="{0:d}, all works fine and show only the date with culture format.

I had the same problem with a different and simple solution.

Problem

I installed PHP 5.6 following the accepted answer to this question on Ask Ubuntu. After using Virtualmin to switch a particular virtual server from PHP 5.5 to PHP 5.6, I received a 500 Internal Server Error and had the same entries in the apache error log:

[Tue Jul 03 16:15:22.131051 2018] [fcgid:warn] [pid 24262] (104)Connection reset by peer: [client 10.20.30.40:23700] mod_fcgid: error reading data from FastCGI server
[Tue Jul 03 16:15:22.131101 2018] [core:error] [pid 24262] [client 10.20.30.40:23700] End of script output before headers: index.php

Cause

Simple: I didn't install the php5.6-cgi packet.

Fix

Installing the packet and reloading apache solved the problem:

• sudo apt-get install php5.6-cgi if you are using PHP 5.6

• sudo apt-get install php5-cgi if you are using a different PHP 5 version

• sudo apt-get install php7.0-cgi if you are using PHP 7

Then use service apache2 reload to apply the configuration.

Would something like this work:

In [7]: df.groupby('dummy').returns.agg({'func1' : lambda x: x.sum(), 'func2' : lambda x: x.prod()})
Out[7]: 
              func2     func1
dummy                        
1     -4.263768e-16 -0.188565

This depends on the alphabet but for the english one, try this:

String input = "abc".toLowerCase(); //note the to lower case in order to treat a and A the same way
for( int i = 0; i < input.length(); ++i) {
   int position = input.charAt(i) - 'a' + 1;
}

Using Stream

private static void copyFileUsingStream(File source, File dest) throws IOException {
    InputStream is = null;
    OutputStream os = null;
    try {
        is = new FileInputStream(source);
        os = new FileOutputStream(dest);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = is.read(buffer)) > 0) {
            os.write(buffer, 0, length);
        }
    } finally {
        is.close();
        os.close();
    }
}

Using Channel

private static void copyFileUsingChannel(File source, File dest) throws IOException {
    FileChannel sourceChannel = null;
    FileChannel destChannel = null;
    try {
        sourceChannel = new FileInputStream(source).getChannel();
        destChannel = new FileOutputStream(dest).getChannel();
        destChannel.transferFrom(sourceChannel, 0, sourceChannel.size());
       }finally{
           sourceChannel.close();
           destChannel.close();
       }
}

Using Apache Commons IO lib:

private static void copyFileUsingApacheCommonsIO(File source, File dest) throws IOException {
    FileUtils.copyFile(source, dest);
}

Using Java SE 7 Files class:

private static void copyFileUsingJava7Files(File source, File dest) throws IOException {
    Files.copy(source.toPath(), dest.toPath());
}

A better way: custom template filter: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

such as get my_list[x] in templates:

in template

{% load index %}
{{ my_list|index:x }}

templatetags/index.py

from django import template
register = template.Library()

@register.filter
def index(indexable, i):
    return indexable[i]

if my_list = [['a','b','c'], ['d','e','f']], you can use {{ my_list|index:x|index:y }} in template to get my_list[x][y]

It works fine with "for"

{{ my_list|index:forloop.counter0 }}

Tested and works well ^_^

It is Safari specific, at least at time of writing, being introduced in Safari 9.0. From the "What's new in Safari?" documentation for Safari 9.0:

Viewport Changes

Viewport meta tags using "width=device-width" cause the page to scale down to fit content that overflows the viewport bounds. You can override this behavior by adding "shrink-to-fit=no" to your meta tag as shown below. The added value will prevent the page from scaling to fit the viewport.

<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">

In short, adding this to the viewport meta tag restores pre-Safari 9.0 behaviour.

Example

Here's a worked visual example which shows the difference upon loading the page in the two configurations.

The red section is the width of the viewport and the blue section is positioned outside the initial viewport (eg left: 100vw). Note how in the first example the page is zoomed to fit when shrink-to-fit=no is omitted (thus showing the out-of-viewport content) and the blue content remains off screen in the latter example.

The code for this example can be found at https://codepen.io/davidjb/pen/ENGqpv.

Without shrink-to-fit specified

With shrink-to-fit=no

I've been able to solve this by using a hack involving import *. It even works for both named and default exports!

For a named export:

// dependency.js
export const doSomething = (y) => console.log(y)

// myModule.js
import { doSomething } from './dependency';

export default (x) => {
  doSomething(x * 2);
}

// myModule-test.js
import myModule from '../myModule';
import * as dependency from '../dependency';

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    dependency.doSomething = jest.fn(); // Mutate the named export

    myModule(2);

    expect(dependency.doSomething).toBeCalledWith(4);
  });
});

Or for a default export:

// dependency.js
export default (y) => console.log(y)

// myModule.js
import dependency from './dependency'; // Note lack of curlies

export default (x) => {
  dependency(x * 2);
}

// myModule-test.js
import myModule from '../myModule';
import * as dependency from '../dependency';

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    dependency.default = jest.fn(); // Mutate the default export

    myModule(2);

    expect(dependency.default).toBeCalledWith(4); // Assert against the default
  });
});

As Mihai Damian quite rightly pointed out below, this is mutating the module object of dependency, and so it will 'leak' across to other tests. So if you use this approach you should store the original value and then set it back again after each test.

To do this easily with Jest, use the spyOn() method instead of jest.fn(), because it supports easily restoring its original value, therefore avoiding before mentioned 'leaking'.

You can do

ls -1 |xargs realpath

If you need to specify an absolute path or relative path You can do that as well

 ls -1 $FILEPATH |xargs realpath

mcc -?

explains that the syntax to make *.exe (Standalone Application) with *.m is:

 mcc -m <matlabFile.m> 

For example:

mcc -m file.m

will create file.exe in the curent directory.

Predicate falls under the category of generic delegates in C#. This is called with one argument and always return the boolean type. Basically, the predicate is used to test the condition - true/false. Many classes support predicate as an argument. For example, list.findall expects the parameter predicate. Here is an example of predicate.

Imagine a function pointer with the signature:

<modifier> bool delegate myDelegate<in T>(T match);

Here is the example:

Node.cs:

namespace PredicateExample
{
    class Node
    {
        public string Ip_Address { get; set; }
        public string Node_Name { get; set; }
        public uint Node_Area { get; set; }
    }
}

Main class:

using System;
using System.Threading;
using System.Collections.Generic;

namespace PredicateExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Predicate<Node> backboneArea = Node =>  Node.Node_Area == 0 ;
            List<Node> Nodes = new List<Node>();
            Nodes.Add(new Node { Ip_Address = "1.1.1.1", Node_Area = 0, Node_Name = "Node1" });
            Nodes.Add(new Node { Ip_Address = "2.2.2.2", Node_Area = 1, Node_Name = "Node2" });
            Nodes.Add(new Node { Ip_Address = "3.3.3.3", Node_Area = 2, Node_Name = "Node3" });
            Nodes.Add(new Node { Ip_Address = "4.4.4.4", Node_Area = 0, Node_Name = "Node4" });
            Nodes.Add(new Node { Ip_Address = "5.5.5.5", Node_Area = 1, Node_Name = "Node5" });
            Nodes.Add(new Node { Ip_Address = "6.6.6.6", Node_Area = 0, Node_Name = "Node6" });
            Nodes.Add(new Node { Ip_Address = "7.7.7.7", Node_Area = 2, Node_Name = "Node7" });

            foreach( var item in Nodes.FindAll(backboneArea))
            {
                Console.WriteLine("Node Name " + item.Node_Name + " Node IP Address " + item.Ip_Address);
            }

            Console.ReadLine();
        }
    }
}

It happens that I'm just starting to learn coding and I needed something similar as you have just asked in SQLite (I´m using [SQLiteStudio] (3.1.1)).

It happens that you must define the column's 'Constraint' as 'Not Null' then entering your desired definition using 'Default' 'Constraint' or it will not work (I don't know if this is an SQLite or the program requirment).

Here is the code I used:

CREATE TABLE <MY_TABLE> (
<MY_TABLE_KEY>       INTEGER    UNIQUE
                                PRIMARY KEY,
<MY_TABLE_SERIAL>    TEXT       DEFAULT (<MY_VALUE>) 
                                NOT NULL
<THE_REST_COLUMNS>
);

The location of the sitemap affects which URLs that it can include, but otherwise there is no standard. Here is a good link with more explaination: http://www.sitemaps.org/protocol.html#location

Just to add another example:

I was replacing src attr in img html tags, but i needed to replace only the src and keep any text between the img declaration and src attribute.

I used the find+replace tool (ctrl+h) as in the image:

There are two basic ways:

url(../../images/image.png)

or

url(/Web/images/image.png)

I prefer the latter, as it's easier to work with and works from all locations in the site (so useful for inline image paths too).

Mind you, I wouldn't do so much deep nesting of folders. It seems unnecessary and makes life a bit difficult, as you've found.

It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)

Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.

Use System.DateTime.DaysInMonth, from code sample:

const int July = 7;
const int Feb = 2;

// daysInJuly gets 31.
int daysInJuly = System.DateTime.DaysInMonth(2001, July);

// daysInFeb gets 28 because the year 1998 was not a leap year.
int daysInFeb = System.DateTime.DaysInMonth(1998, Feb);

// daysInFebLeap gets 29 because the year 1996 was a leap year.
int daysInFebLeap = System.DateTime.DaysInMonth(1996, Feb);

Keep it simple!

An AsyncTask is background task which runs in the background thread. It takes an Input, performs Progress and gives Output.

ie AsyncTask<Input,Progress,Output>.

In my opinion the main source of confusion comes when we try to memorize the parameters in the AsyncTask.
The key is Don't memorize.
If you can visualize what your task really needs to do then writing the AsyncTask with the correct signature would be a piece of cake.
Just figure out what your Input, Progress and Output are and you will be good to go.

For example:

Heart of the AsyncTask!

doInBackgound() method is the most important method in an AsyncTask because

• Only this method runs in the background thread and publish data to UI thread.
• Its signature changes with the AsyncTask parameters.

So lets see the relationship

doInBackground() and onPostExecute(),onProgressUpdate() are also related

Show me the code
So how will I write the code for DownloadTask?

DownloadTask extends AsyncTask<String,Integer,String>{

      @Override
      public void onPreExecute()
      {}

      @Override
      public String doInbackGround(String... params)
      {
               // Download code
               int downloadPerc = // calculate that
               publish(downloadPerc);

               return "Download Success";
      }

      @Override
      public void onPostExecute(String result)
      {
          super.onPostExecute(result);
      }

      @Override
      public void onProgressUpdate(Integer... params)
      {
             // show in spinner, access UI elements
      }

}

How will you run this Task

new DownLoadTask().execute("Paradise.mp3");

For example, a feature only works for api21 up the following we fix bugs in api21 down

    if(Build.VERSION.SDK_INT >= 21) {
    //only api 21 above
    }else{
   //only api 21 down
    }

If you're willing to transmit some data and that you don't need to be secured (any public infos) you can use a CORS proxy, it's very easy, you'll not have to change anything in your code or in server side (especially of it's not your server like the Yahoo API or OpenWeather). I've used it to fetch JSON files with an XMLHttpRequest and it worked fine.

Unix has a variable called PATH that is a list of directories where to find commands.

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/david/bin

If I type a command foo at the command line, my shell will first see if there's an executable command /usr/local/bin/foo. If there is, it will execute /usr/local/bin/foo. If not, it will see if there's an executable command /usr/bin/foo and if not there, it will look to see if /bin/foo exists, etc. until it gets to /Users/david/bin/foo.

If it can't find a command foo in any of those directories, it tell me command not found.

There are several ways I can handle this issue:

• Use the commandbash foo since foo is a shell script.
• Include the directory name when you eecute the command like /Users/david/foo or $PWD/foo or just plain ./foo.
• Change your $PATH variable to add the directory that contains your commands to the PATH.

You can modify $HOME/.bash_profile or $HOME/.profile if .bash_profile doesn't exist. I did that to add in /usr/local/bin which I placed first in my path. This way, I can override the standard commands that are in the OS. For example, I have Ant 1.9.1, but the Mac came with Ant 1.8.4. I put my ant command in /usr/local/bin, so my version of antwill execute first. I also added $HOME/bin to the end of the PATH for my own commands. If I had a file like the one you want to execute, I'll place it in $HOME/bin to execute it.

You typically do commit .gitignore. In fact, I personally go as far as making sure my index is always clean when I'm not working on something. (git status should show nothing.)

There are cases where you want to ignore stuff that really isn't project specific. For example, your text editor may create automatic *~ backup files, or another example would be the .DS_Store files created by OS X.

I'd say, if others are complaining about those rules cluttering up your .gitignore, leave them out and instead put them in a global excludes file.

By default this file resides in $XDG_CONFIG_HOME/git/ignore (defaults to ~/.config/git/ignore), but this location can be changed by setting the core.excludesfile option. For example:

git config --global core.excludesfile ~/.gitignore

Simply create and edit the global excludesfile to your heart's content; it'll apply to every git repository you work on on that machine.

I came across this question while searching for a way to pick out the first item in one array that does not match any of the values in another array and managed to sort it out eventually with array.find() and array.filter() like this

var carList= ['mercedes', 'lamborghini', 'bmw', 'honda', 'chrysler'];
var declinedOptions = ['mercedes', 'lamborghini'];

const nextOption = carList.find(car=>{
    const duplicate = declinedOptions.filter(declined=> {
      return declined === car
    })
    console.log('duplicate:',duplicate) //should list out each declined option
    if(duplicate.length === 0){//if theres no duplicate, thats the nextOption
      return car
    }
})

console.log('nextOption:', nextOption);
//expected outputs
//duplicate: mercedes
//duplicate: lamborghini
//duplicate: []
//nextOption: bmw

if you need to keep fetching an updated list before cross-checking for the next best option this should work well enough :)

Your requirements are all over the place, but this is the solution to my understanding of them:

To group by Reference property:

var refGroupQuery = (from m in context.Measurements
            group m by m.Reference into refGroup
            select refGroup);

Now you say you want to limit results by "most recent numOfEntries" - I take this to mean you want to limit the returned Measurements... in that case:

var limitedQuery = from g in refGroupQuery
                   select new
                   {
                       Reference = g.Key,
                       RecentMeasurements = g.OrderByDescending( p => p.CreationTime ).Take( numOfEntries )
                   }

To order groups by first Measurement creation time (note you should order the measurements; if you want the earliest CreationTime value, substitue "g.SomeProperty" with "g.CreationTime"):

var refGroupsOrderedByFirstCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.OrderBy( g => g.SomeProperty ).First().CreationTime );

To order groups by average CreationTime, use the Ticks property of the DateTime struct:

var refGroupsOrderedByAvgCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.Average( g => g.CreationTime.Ticks ) );

The problem with editing JavaScript like you can CSS and HTML is that there is no clean way to propagate the changes. JavaScript can modify the DOM, send Ajax requests, and dynamically modify existing objects and functions at runtime. So, once you have loaded a page with JavaScript, it might be completely different after the JavaScript has run. The browser would have to keep track of every modification your JavaScript code performs so that when you edit the JS, it rolls back the changes to a clean page.

But, you can modify JavaScript dynamically a few other ways:

• JavaScript injections in the URL bar: javascript: alert (1);
• Via a JavaScript console (there's one built into Firefox, Chrome, and newer versions of IE
• If you want to modify the JavaScript files as they are served to your browser (i.e. grabbing them in transit and modifying them), then I can't offer much help. I would suggest using a debugging proxy: http://www.fiddler2.com/fiddler2/

The first two options are great because you can modify any JavaScript variables and functions currently in scope. However, you won't be able to modify the code and run it with a "just-served" page like you can with the third option.

Other than that, as far as I know, there is no edit-and-run JavaScript editor in the browser. Hope this helps,

If the file that you want to open is in the same folder as your batch(.bat) file then you can simply try:

start filename.filetype

example: start image.png

A little late here, but I've found this to be a common problem worth a custom directive to handle. Here's how that might look:

  .directive('toggleOnHover', function(){
    return {
      restrict: 'A',
      link: link
    };

    function link(scope, elem, attrs){
      elem.on('mouseenter', applyToggleExp);
      elem.on('mouseleave', applyToggleExp);

      function applyToggleExp(){
        scope.$apply(attrs.toggleOnHover);
      }
    }

  });

You can use it like this:

<li toggle-on-hover="editableProp = !editableProp">edit</li> 

This code can be used with timezone

javascript:

let minToHm = (m) => {_x000D_
  let h = Math.floor(m / 60);_x000D_
  h += (h < 0) ? 1 : 0;_x000D_
  let m2 = Math.abs(m % 60);_x000D_
  m2 = (m2 < 10) ? '0' + m2 : m2;_x000D_
  return (h < 0 ? '' : '+') + h + ':' + m2;_x000D_
}_x000D_
_x000D_
console.log(minToHm(210)) // "+3:30"_x000D_
console.log(minToHm(-210)) // "-3:30"_x000D_
console.log(minToHm(0)) // "+0:00"

minToHm(210)
"+3:30"

minToHm(-210)
"-3:30"

minToHm(0)
"+0:00"

If the error you are facing is "unable to connect to remote server" as was mine, then it would benefit you to have this check as well in addition to the checks provided in the above comments.

I saw that there were 2 NUGET Package Sources from which the packages could be downloaded (within Tools->Nuget Package Manager->Packager Manager Settings). One of the Package Source's was not functioning and Nuget was trying to download from that source only.

Things fell into place once I changed the package source to download from: https://www.nuget.org/api/v2/ EXPLICTLY in the settings

Here is the typical structure of new Codeigniter project:

- application/
- system/
- user_guide/
- index.php <- this is the file you need to change

I usually use this code in my CI index.php. Just change local_server_name to the name of your local webserver.

With this code you can deploy your site to your production server without changing index.php each time.

// Domain-based environment
if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

/*
 *---------------------------------------------------------------
 * ERROR REPORTING
 *---------------------------------------------------------------
 *
 * Different environments will require different levels of error reporting.
 * By default development will show errors but testing and live will hide them.
 */

if (defined('ENVIRONMENT')) {
    switch (ENVIRONMENT) {
        case 'development':
            error_reporting(E_ALL);
            break;
        case 'testing':
        case 'production':
            error_reporting(0);
            ini_set('display_errors', 0);  
            break;
        default:
            exit('The application environment is not set correctly.');
    }
}

If Perl 5.10+ is not an option, here is a quick and dirty approximation. It's not exactly the same, since say has some magic when its first arg is a handle, but for printing to STDOUT:

sub say {print @_, "\n"}

say 'hello';

From the docs use sample():

In [79]: s = pd.Series([0,1,2,3,4,5])

# When no arguments are passed, returns 1 row.
In [80]: s.sample()
Out[80]: 
0    0
dtype: int64

# One may specify either a number of rows:
In [81]: s.sample(n=3)
Out[81]: 
5    5
2    2
4    4
dtype: int64

# Or a fraction of the rows:
In [82]: s.sample(frac=0.5)
Out[82]: 
5    5
4    4
1    1
dtype: int64

With the following extension method you can get away without reflection:

public static Type GetListType<T>(this List<T> _)
{
    return typeof(T);
}

Or more general:

public static Type GetEnumeratedType<T>(this IEnumerable<T> _)
{
    return typeof(T);
}

Usage:

List<string>        list    = new List<string> { "a", "b", "c" };
IEnumerable<string> strings = list;
IEnumerable<object> objects = list;

Type listType    = list.GetListType();           // string
Type stringsType = strings.GetEnumeratedType();  // string
Type objectsType = objects.GetEnumeratedType();  // BEWARE: object

If your values are non-null strings or numbers, you can use an object as a dictionary:

var map = {}, result = [], i;
for (i = 0; i < array1.length; ++i) {
    map[array1[i]] = 1;
}

for (i = 0; i < array2.length; ++i) {
    if (map[array2[i]] === 1) {
        result.push(array2[i]);

        // avoid returning a value twice if it appears twice in array 2
        map[array2[i]] = 0;
    }
}

return result;

Some extensions like blocksite use the accessibility service API to deploy extension like features to Chrome on Android. Might be worth a look through the play store. Otherwise, Firefox is your best bet, though many extensions don't work on mobile for some reason.

https://play.google.com/store/apps/details?id=co.blocksite&hl=en_US

In addition, you can simply convert byte array to Bitmap.

var bmp = new Bitmap(new MemoryStream(imgByte));

You can also get Bitmap from file Path directly.

Bitmap bmp = new Bitmap(Image.FromFile(filePath));

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

i used to do like this

inside view

<script type="text/javascript">

//will replace the '_transactionIds_' and '_payeeId_' 
var _addInvoiceUrl = '@(Html.Raw( Url.Action("PayableInvoiceMainEditor", "Payables", new { warehouseTransactionIds ="_transactionIds_",payeeId = "_payeeId_", payeeType="Vendor" })))';

on javascript file

var url = _addInvoiceUrl.replace('_transactionIds_', warehouseTransactionIds).replace('_payeeId_', payeeId);
        window.location.href = url;

in this way i can able to pass the parameter values on demand..

by using @Html.Raw, url will not get amp; for parameters

string str = Console.ReadLine(); //Reads a character from console
double a = double.Parse(str); //Converts str into the type double
double b = a * Math.PI; // Multiplies by PI
Console.WriteLine("{0}", b); // Writes the number to console

Console.Read() reads a string from console A SINGLE CHARACTER AT A TIME (but waits for an enter before going on. You normally use it in a while cycle). So if you write 25 + Enter, it will return the unicode value of 2 that is 50. If you redo a second Console.Read() it will return immediately with 53 (the unicode value of 5). A third and a fourth Console.Read() will return the end of line/carriage characters. A fifth will wait for new input.

Console.ReadLine() reads a string (so then you need to change the string to a double)

One way we do this in our application is using IDisposable and then with using(){} blocks to ensure the cursor is reset when done.

public class OverrideCursor : IDisposable
{

  public OverrideCursor(Cursor changeToCursor)
  {
    Mouse.OverrideCursor = changeToCursor;
  }

  #region IDisposable Members

  public void Dispose()
  {
    Mouse.OverrideCursor = null;
  }

  #endregion
}

and then in your code:

using (OverrideCursor cursor = new OverrideCursor(Cursors.Wait))
{
  // Do work...
}

The override will end when either: the end of the using statement is reached or; if an exception is thrown and control leaves the statement block before the end of the statement.

Update

To prevent the cursor flickering you can do:

public class OverrideCursor : IDisposable
{
  static Stack<Cursor> s_Stack = new Stack<Cursor>();

  public OverrideCursor(Cursor changeToCursor)
  {
    s_Stack.Push(changeToCursor);

    if (Mouse.OverrideCursor != changeToCursor)
      Mouse.OverrideCursor = changeToCursor;
  }

  public void Dispose()
  {
    s_Stack.Pop();

    Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;

    if (cursor != Mouse.OverrideCursor)
      Mouse.OverrideCursor = cursor;
  }

}

Not a lot to go on there, but I think what you're looking for is to flip the width and max-width values:

#container2 {
  width: 90%;
  max-width: 960px;
  /* etc, etc... */
}

That'll give you a container that's 90% of the width of the available space, up to a maximum of 960px, but that's dependent on its container being resizable itself. Responsive design is a whole big ball of wax though, so this doesn't even scratch the surface.

If you are using C99 just include stdint.h. BTW, the 64bit types are there iff the processor supports them.

this will work for u

   $("#button-name").click(function(){
        $('#toggle-id').slideToggle('slow');
    });

Go to Window -- Preferances - General -- Startup and Shutdown -Workspaces

Check box for Prompt for workspace on startup is there . Select it.

Then at start up eclipse will ask for workspace selection.

---- EDIT ----

On OSX the Eclipse(Juno) menu bar path is:

Eclipse - Preferences

In the preferences dialog box, I selected the tree node:

 General - Startup and Shutdown - Workspaces

From that panel, there was a check box labeled

**Prompt for workspace on startup** 

I checked it, then shut down eclipse and restarted it. It prompted me for a new workspace location.

You can get free Virtual Machine and many more things online for 3 months provided by Microsoft Azure. I guess you need VPN for learning purpose. For that it would suffice.

First if the object you're dealing with is a string then you need to parse it then figure out the length of the keys :

obj = JSON.parse(jsonString);
shareInfoLen = Object.keys(obj.shareInfo[0]).length;

how about complex types? when array contains objects... or any else

My variant:

Object.prototype.copy = function(){
    var v_newObj = {};
    for(v_i in this)
        v_newObj[v_i] = (typeof this[v_i]).contains(/^(array|object)$/) ? this[v_i].copy() : this[v_i];
    return v_newObj;
}

Array.prototype.copy = function(){
    var v_newArr = [];
    this.each(function(v_i){
        v_newArr.push((typeof v_i).contains(/^(array|object)$/) ? v_i.copy() : v_i);
    });
    return v_newArr;
}

It's not final version, just an idea.

PS: method each and contains are prototypes also.

Cursors are used when your select query returns multiple rows. So, rather using cursor in case when you want aggregates or single rowdata you could use a procedure/function without cursor as well like

  Create Procedure sample(id 
    varchar2(20))as 
    Select count(*) into x from table 
    where 
       Userid=id;
     End ;

And then simply call the procedure

   Begin
   sample(20);
   End

This is the actual use of procedure/function mostly wrapping and storing queries that are complex or that requires repeated manipulation with same logic but different data

npm config edit

Opens the config file in an editor. Use the --global flag to edit the global config. now you can delete what ever the registry's you don't want and save file.

npm config list will display the list of available now.

The ast.literal_eval function comes close, but it will expect the string to be properly quoted first.

Of course Python's interpretation of backslash escapes depends on how the string is quoted ("" vs r"" vs u"", triple quotes, etc) so you may want to wrap the user input in suitable quotes and pass to literal_eval. Wrapping it in quotes will also prevent literal_eval from returning a number, tuple, dictionary, etc.

Things still might get tricky if the user types unquoted quotes of the type you intend to wrap around the string.

Even shorter and with json-functions:

JSONObject songsObject = json.getJSONObject("songs");
JSONArray songsArray = songsObject.toJSONArray(songsObject.names());

Apply style="text-align: right" to the input tag. This will allow entry to be right-justified, and (at least in Firefox 3, IE 7 and Safari) will even appear to flow from the right.

1.1) First-level cache

First-level cache always Associates with the Session object. Hibernate uses this cache by default. Here, it processes one transaction after another one, means wont process one transaction many times. Mainly it reduces the number of SQL queries it needs to generate within a given transaction. That is instead of updating after every modification done in the transaction, it updates the transaction only at the end of the transaction.

1.2) Second-level cache

Second-level cache always associates with the Session Factory object. While running the transactions, in between it loads the objects at the Session Factory level, so that those objects will be available to the entire application, not bound to single user. Since the objects are already loaded in the cache, whenever an object is returned by the query, at that time no need to go for a database transaction. In this way the second level cache works. Here we can use query level cache also.

Building off of @gnovice's answer, you can actually create filled plots with shading only in the area between the two curves. Just use fill in conjunction with fliplr.

Example:

x=0:0.01:2*pi;                  %#initialize x array
y1=sin(x);                      %#create first curve
y2=sin(x)+.5;                   %#create second curve
X=[x,fliplr(x)];                %#create continuous x value array for plotting
Y=[y1,fliplr(y2)];              %#create y values for out and then back
fill(X,Y,'b');                  %#plot filled area

By flipping the x array and concatenating it with the original, you're going out, down, back, and then up to close both arrays in a complete, many-many-many-sided polygon.

You can't do this: {this.state.arrayFromJson} As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map to do that.

I am pasting a link from where you can learn how to render elements from an array with React.

See How to: Determine Which .NET Framework Versions Are Installed (MSDN).

MSDN proposes one function example that seems to do the job for version 1-4. According to the article, the method output is:

v2.0.50727  2.0.50727.4016  SP2
v3.0  3.0.30729.4037  SP2
v3.5  3.5.30729.01  SP1
v4
  Client  4.0.30319
  Full  4.0.30319

Note that for "versions 4.5 and later" there is another function.

extension Date {
    
    func get(_ type: Calendar.Component)-> String {
        let calendar = Calendar.current
        let t = calendar.component(type, from: self)
        return (t < 10 ? "0\(t)" : t.description)
    }
}

Usage:

print(Date().get(.year)) // => 2020
print(Date().get(.month)) // => 08
print(Date().get(.day)) // => 18

The move_uploaded_file will return false if the file was not successfully moved you can put something into your code to alert you in a log if that happens, that should help you figure out why your having trouble renaming the file

MyEclipse (eclipse based, subscription required) and Webclipse (an eclipse plug-in, currently free), from my company, Genuitec, have newly engineered (as of 2015) JavaScript debugging built in:

You can debug both generic web applications and Node.js files.

I had a ton of trouble with this and then found a great solution:

Create a file in a text editor called whoami.php with the below code as it's content, save the file and upload it to public_html (or whatever you root of your webserver directory is named). It should output a useful string that you can use to track down the user the webserver is running as, my output was "php is running as user: nt authority\iusr" which allowed me to track down the permissions I needed to modify to the user "IUSR".

<?php
  // outputs the username that owns the running php/httpd process
  // (on a system with the "whoami" executable in the path)
  echo 'php is running as user: ' . exec('whoami');
?>

You were just one step away from incorporating the row count into the base dataset.

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

@param won't affect the number. It's just for making javadocs.

Instead of saving it to a file, save it to php://output^­Docs:

$objWriter->save('php://output');

This will send it AS-IS to the browser.

You want to add some headers^­Docs first, like it's common with file downloads, so the browser knows which type that file is and how it should be named (the filename):

// We'll be outputting an excel file
header('Content-type: application/vnd.ms-excel');

// It will be called file.xls
header('Content-Disposition: attachment; filename="file.xls"');

// Write file to the browser
$objWriter->save('php://output');

First do the headers, then the save. For the excel headers see as well the following question: Setting mime type for excel document.

The behavior of defaultdict can be easily mimicked using dict.setdefault instead of d[key] in every call.

In other words, the code:

from collections import defaultdict

d = defaultdict(list)

print(d['key'])                        # empty list []
d['key'].append(1)                     # adding constant 1 to the list
print(d['key'])                        # list containing the constant [1]

is equivalent to:

d = dict()

print(d.setdefault('key', list()))     # empty list []
d.setdefault('key', list()).append(1)  # adding constant 1 to the list
print(d.setdefault('key', list()))     # list containing the constant [1]

The only difference is that, using defaultdict, the list constructor is called only once, and using dict.setdefault the list constructor is called more often (but the code may be rewriten to avoid this, if really needed).

Some may argue there is a performance consideration, but this topic is a minefield. This post shows there isn't a big performance gain in using defaultdict, for example.

IMO, defaultdict is a collection that adds more confusion than benefits to the code. Useless for me, but others may think different.

Well seeing this thread as a beginner got my head spinning. Hence came up with a simple shortcut.

Though str.strip() works to remove leading & trailing spaces it does nothing for spaces between characters.

words=input("Enter the word to test")
# If I have a user enter discontinous threads it becomes a problem
# input = "   he llo, ho w are y ou  "
n=words.strip()
print(n)
# output "he llo, ho w are y ou" - only leading & trailing spaces are removed 

Instead use str.replace() to make more sense plus less error & more to the point. The following code can generalize the use of str.replace()

def whitespace(words):
    r=words.replace(' ','') # removes all whitespace
    n=r.replace(',','|') # other uses of replace
    return n
def run():
    words=input("Enter the word to test") # take user input
    m=whitespace(words) #encase the def in run() to imporve usability on various functions
    o=m.count('f') # for testing
    return m,o
print(run())
output- ('hello|howareyou', 0)

Can be helpful while inheriting the same in diff. functions.

Use numbered items to prevent replacing again. eg

let str = "I have a %1, a %2, and a %3";
let pets = ["dog","cat", "goat"];

then

str.replace(/%(\d+)/g, (_, n) => pets[+n-1])

How it works:- %\d+ finds the numbers which come after a %. The brackets capture the number.

This number (as a string) is the 2nd parameter, n, to the lambda function.

The +n-1 converts the string to the number then 1 is subtracted to index the pets array.

The %number is then replaced with the string at the array index.

The /g causes the lambda function to be called repeatedly with each number which is then replaced with a string from the array.

In modern JavaScript:-

replace_n=(str,...ns)=>str.replace(/%(\d+)/g,(_,n)=>ns[n-1])

additionally to @franc's answer you can use this from sql interface:

select 
    prosrc
from pg_trigger, pg_proc
where
 pg_proc.oid=pg_trigger.tgfoid
 and pg_trigger.tgname like '<name>'

(taken from here: http://www.postgresql.org/message-id/Pine.BSF.4.10.10009140858080.28013-100000@megazone23.bigpanda.com)

I believe GUIDs are constrained to 16-byte lengths (or 32 bytes for an ASCII hex equivalent).

You can use a CROSS JOIN:

SELECT *
FROM (  SELECT SUM(Fdays) AS fDaysSum 
        FROM tblFieldDays 
        WHERE tblFieldDays.NameCode=35 
        AND tblFieldDays.WeekEnding=1) A -- use you real query here
CROSS JOIN (SELECT SUM(CHdays) AS hrsSum 
            FROM tblChargeHours 
            WHERE tblChargeHours.NameCode=35 
            AND tblChargeHours.WeekEnding=1) B -- use you real query here

I have come across this with the Hero, using what I thought was a published API. In the end, I used a test to see if the intent could be received:

private boolean isCallable(Intent intent) {
    List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent, 
        PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

In use when I would usually just start the activity:

final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");
if (isCallable(intent)) {
    // call the intent as you intended.
} else {
    // make alternative arrangements.
}

obvious: If you go down this route - using non-public APIs - you must absolutely provide a fallback which you know definitely works. It doesn't have to be perfect, it can be a Toast saying that this is unsupported for this handset/device, but you should avoid an uncaught exception. end obvious.

I find the Open Intents Registry of Intents Protocols quite useful, but I haven't found the equivalent of a TCK type list of intents which absolutely must be supported, and examples of what apps do different handsets.

The '\r' character is the carriage return, and the carriage return-newline pair is both needed for newline in a network virtual terminal session.

From the old telnet specification (RFC 854) (page 11):

The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").

However, from the latest specification (RFC5198) (page 13):

1. ...

2. In Net-ASCII, CR MUST NOT appear except when immediately followed by either NUL or LF, with the latter (CR LF) designating the "new line" function. Today and as specified above, CR should generally appear only when followed by LF. Because page layout is better done in other ways, because NUL has a special interpretation in some programming languages, and to avoid other types of confusion, CR NUL should preferably be avoided as specified above.

3. LF CR SHOULD NOT appear except as a side-effect of multiple CR LF sequences (e.g., CR LF CR LF).

So newline in Telnet should always be '\r\n' but most implementations have either not been updated, or keeps the old '\n\r' for backwards compatibility.

There are 3 problems.

1) Incorrect decimal separator

Different cultures use different decimal separators (namely , and .).

If you replace . with , it should work as expected:

Console.WriteLine(Convert.ToDouble("52,8725945"));

You can parse your doubles using overloaded method which takes culture as a second parameter. In this case you can use InvariantCulture (What is the invariant culture) e.g. using double.Parse:

double.Parse("52.8725945", System.Globalization.CultureInfo.InvariantCulture);

You should also take a look at double.TryParse, you can use it with many options and it is especially useful to check wheter or not your string is a valid double.

2) You have an incorrect double

One of your values is incorrect, because it contains two dots:

15.5859949000000662452.23862099999999

3) Your array has an empty value at the end, which is an incorrect double

You can use overloaded Split which removes empty values:

string[] someArray = a.Split(new char[] { '#' }, StringSplitOptions.RemoveEmptyEntries);

replaceAll(search, replaceWith) [MDN]

 ".a.b.c.".replaceAll('.', ' ')
 // result: " a b c "

 // Using RegEx. You MUST use a global RegEx.
 ".a.b.c.".replaceAll(/\./g, ' ')
 // result: " a b c "
    

replaceAll() replaces ALL occurrences of search with replaceWith.

It's actually the same as using replace() [MDN] with a global regex(*), merely replaceAll() is a bit more readable in my view.

(*) Meaning it'll match all occurrences.

Important(!) if you choose regex:

when using a regexp you have to set the global ("g") flag; otherwise, it will throw a TypeError: "replaceAll must be called with a global RegExp".

Your best bet is

$(document).keyup(function(e) { 
    if (e.which === 13) $('.save').click();   // enter 
    if (e.which === 27) $('.cancel').click(); // esc   

    /* OPTIONAL: Only if you want other elements to ignore event */
    e.preventDefault();
    e.stopPropagation();
});

Summary

• which is more preferable than keyCode because it is normalized
• keyup is more preferable than keydown because keydown may occur multiple times if user keeps it pressed.
• Do not use keypress unless you want to capture actual characters.

Interestingly Bootstrap uses keydown and keyCode in its dropdown component (as of 3.0.2)! I think it's probably poor choice there.

Related snippet from JQuery doc

While browsers use differing properties to store this information, jQuery normalizes the .which property so you can reliably use it to retrieve the key code. This code corresponds to a key on the keyboard, including codes for special keys such as arrows. For catching actual text entry, .keypress() may be a better choice.

After someone else's website crawl, I ended up with thousands of files missing the .html extension, across a wide tree of subdirectories.

To rename them all in one shot, except the files already having a .html extension (most of them had none at all), this worked for me:

cd wwwroot
find . -xtype f \! -iname *.html   -exec mv -iv "{}"  "{}.html"  \;  # batch rename files to append .html suffix IF MISSING

In the OP's case I might modify that slightly, to only rename *.txt files, like so:

find . -xtype f  -iname *.txt   -exec filename="{}"  mv -iv ${filename%.*}.{txt,html}  \; 

Broken down (hammertime!):

-iname *.txt
- Means consider ONLY files already ending in .txt

mv -iv "{}.{txt,html}" - When find passes a {} as the filename, ${filename%.*} extracts its basename without any extension to form the parameters to mv. bash takes the {txt,html} to rewrite it as two parameters so the final command runs as: mv -iv "filename.txt" "filename.html"

Fix needed though: dealing with spaces in filenames

async/await

const { promisify } = require("util")
const directory = path.join(__dirname, "/tmpl")
const pathnames = promisify(fs.readdir)(directory)

try {
  async function emitData(directory) {
    let filenames = await pathnames
    var ob = {}
    const data = filenames.map(async function(filename, i) {
      if (filename.includes(".")) {
        var storedFile = promisify(fs.readFile)(directory + `\\${filename}`, {
          encoding: "utf8",
        })
        ob[filename.replace(".js", "")] = await storedFile
        socket.emit("init", { data: ob })
      }
      return ob
    })
  }

  emitData(directory)
} catch (err) {
  console.log(err)
}

Who wants to try with generators?

Also you can try this, if you want to focus on same text after error.

If you wants to show this error message in a paragraph then you can use this one:

 $(document).ready(function () {
    $("#submit").click(function () {
        if($('#selBooks').val() === '') {
            $("#Paragraph_id").text("Please select a book and then proceed.").show();
            $('#selBooks').focus();
            return false;
        }
    });
 });

To check if a folder exists or not, you can simply use the exists() method:

// Create a File object representing the folder 'A/B'
def folder = new File( 'A/B' )

// If it doesn't exist
if( !folder.exists() ) {
  // Create all folders up-to and including B
  folder.mkdirs()
}

// Then, write to file.txt inside B
new File( folder, 'file.txt' ).withWriterAppend { w ->
  w << "Some text\n"
}

For Capitalisation in EditText you can choose the below two input types:

1. android:inputType="textCapSentences"
2. android:inputType="textCapWords"

textCapSentences
This will let the first letter of the first word as Capital in every sentence.

textCapWords This will let the first letter of every word as Capital.

If you want both the attributes just use | sign with both the attributes

android:inputType="textCapSentences|textCapWords"

I have run into problems in the past with IE and the css:hover selector so the approach that I have taken, is to use a custom directive.

.directive('hoverClass', function () {
    return {
        restrict: 'A',
        scope: {
            hoverClass: '@'
        },
        link: function (scope, element) {
            element.on('mouseenter', function() {
                element.addClass(scope.hoverClass);
            });
            element.on('mouseleave', function() {
                element.removeClass(scope.hoverClass);
            });
        }
    };
})

then on the element itself you can add the directive with the class names that you want enabled when the mouse is over the the element for example:

<li data-ng-repeat="item in social" hover-class="hover tint" class="social-{{item.name}}" ng-mouseover="hoverItem(true);" ng-mouseout="hoverItem(false);"
                index="{{$index}}"><i class="{{item.icon}}"
                box="course-{{$index}}"></i></li>

This should add the class hover and tint when the mouse is over the element and doesn't run the risk of a scope variable name collision. I haven't tested but the mouseenter and mouseleave events should still bubble up to the containing element so in the given scenario the following should still work

<div hover-class="hover" data-courseoverview data-ng-repeat="course in courses | orderBy:sortOrder | filter:search"
 data-ng-controller ="CourseItemController"
 data-ng-class="{ selected: isSelected }">

providing of course that the li's are infact children of the parent div

It was recently identified that Composer consumes high CPU + memory on packages that have a lot of historical tags. See composer/composer#7577

A workaround to this problem is using symfony/flex or https://github.com/rubenrua/symfony-clean-tags-composer-plugin

So here's what I did to make it dismiss after touching the background or return. I had to add the delegate = self in viewDidLoad and then also the delegate methods later in the .m files.

.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITextFieldDelegate>


@property (strong, atomic) UITextField *username;

@end

.m
- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    self.view.backgroundColor = [UIColor blueColor];
    self.username = [[UITextField alloc] initWithFrame:CGRectMake(100, 25, 80, 20)];
    self.username.placeholder = @"Enter your username";
    self.username.backgroundColor = [UIColor whiteColor];
    self.username.borderStyle = UITextBorderStyleRoundedRect;
    if (self.username.placeholder != nil) {
        self.username.clearsOnBeginEditing = NO;
    }
    self.username.delegate = self;
    [self.username resignFirstResponder];
    [self.view addSubview:self.username];


}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    return YES;
}



- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

@end

@Davy Ladman your solution with shift are corrent but only for ip starting with number less or equal 99, infact first octect must be cast up to long.

Anyway convert back with long type is quite difficult because store 64 bit (not 32 for Ip) and fill 4 bytes with zeroes

static uint ToInt(string addr)
{
   return BitConverter.ToUInt32(IPAddress.Parse(addr).GetAddressBytes(), 0);
}

static string ToAddr(uint address)
{
    return new IPAddress(address).ToString();
}

Enjoy!

Simple solution

setcookie("NAME", "VALUE", time()+3600, '/', EXAMPLE.COM);

Setcookie's 5th parameter determines the (sub)domains that the cookie is available to. Setting it to (EXAMPLE.COM) makes it available to any subdomain (eg: SUBDOMAIN.EXAMPLE.COM )

There is a new method what came with Angular 7.2.0

https://angular.io/api/router/NavigationExtras#state

Send:

this.router.navigate(['action-selection'], { state: { example: 'bar' } });

Receive:

constructor(private router: Router) {
  console.log(this.router.getCurrentNavigation().extras.state.example); // should log out 'bar'
}

You can find some additional info here:

https://github.com/angular/angular/pull/27198

The link above contains this example which can be useful: https://stackblitz.com/edit/angular-bupuzn

Try this : write below code on body & feel the magic :)

body oncontextmenu="return false"

The solution below was the best format I found.

The official docker answer to Run multiple services in a container.

It explains how you can do it with an init system (systemd, sysvinit, upstart) , a script (CMD ./my_wrapper_script.sh) or a supervisor like supervisord.

The && workaround can work only for services that starts in background (daemons) or that will execute quickly without interaction and release the prompt. Doing this with an interactive service (that keeps the prompt) and only the first service will start.

The others told you enough about your issue with multiple calls of readLine().

I just wanted to leave sth about code style: While you see this line = assignement and != null check together in one while condition in most examples (like @gotomanners example here) I prefer using a for for it.

It is much more readable in my opinion ...

for (String line = in.readLine(); line != null; line = in.readLine()) {
    ...
}

Another nice way to write it you see in @TheCapn's example. But when you write it that way you easily see that's what a for-loop is made for.

I do not like assignments scrambled with conditions in one line. It is bad style in my opinion. But because it is so MUCH popular for that special case here to do it that way I would not consider it really bad style. (But cannot understand who established this bad style to become that popular.)

Changing com.android.tools.build:gradle:2.2.0-beta1 to com.android.tools.build:gradle:2.1.2 fixed it for me.

My Android Studio version is 2.1.2, perhaps that's why

To me the key thing about this is: an InterruptedException is not anything going wrong, it is the thread doing what you told it to do. Therefore rethrowing it wrapped in a RuntimeException makes zero sense.

In many cases it makes sense to rethrow an exception wrapped in a RuntimeException when you say, I don't know what went wrong here and I can't do anything to fix it, I just want it to get out of the current processing flow and hit whatever application-wide exception handler I have so it can log it. That's not the case with an InterruptedException, it's just the thread responding to having interrupt() called on it, it's throwing the InterruptedException in order to help cancel the thread's processing in a timely way.

So propagate the InterruptedException, or eat it intelligently (meaning at a place where it will have accomplished what it was meant to do) and reset the interrupt flag. Note that the interrupt flag gets cleared when the InterruptedException gets thrown; the assumption the Jdk library developers make is that catching the exception amounts to handling it, so by default the flag is cleared.

So definitely the first way is better, the second posted example in the question is not useful unless you don't expect the thread to actually get interrupted, and interrupting it amounts to an error.

Here's an answer I wrote describing how interrupts work, with an example. You can see in the example code where it is using the InterruptedException to bail out of a while loop in the Runnable's run method.

The remove operation on a list is given a value to remove. It searches the list to find an item with that value and deletes the first matching item it finds. It is an error if there is no matching item, raises a ValueError.

>>> x = [1, 0, 0, 0, 3, 4, 5]
>>> x.remove(4)
>>> x
[1, 0, 0, 0, 3, 5]
>>> del x[7]
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    del x[7]
IndexError: list assignment index out of range

The del statement can be used to delete an entire list. If you have a specific list item as your argument to del (e.g. listname[7] to specifically reference the 8th item in the list), it'll just delete that item. It is even possible to delete a "slice" from a list. It is an error if there index out of range, raises a IndexError.

>>> x = [1, 2, 3, 4]
>>> del x[3]
>>> x
[1, 2, 3]
>>> del x[4]
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    del x[4]
IndexError: list assignment index out of range

The usual use of pop is to delete the last item from a list as you use the list as a stack. Unlike del, pop returns the value that it popped off the list. You can optionally give an index value to pop and pop from other than the end of the list (e.g listname.pop(0) will delete the first item from the list and return that first item as its result). You can use this to make the list behave like a queue, but there are library routines available that can provide queue operations with better performance than pop(0) does. It is an error if there index out of range, raises a IndexError.

>>> x = [1, 2, 3] 
>>> x.pop(2) 
3 
>>> x 
[1, 2]
>>> x.pop(4)
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    x.pop(4)
IndexError: pop index out of range

See collections.deque for more details.

This is the function I use in my JS:

function toArray(nl) {
    for(var a=[], l=nl.length; l--; a[l]=nl[l]);
    return a;
}

If you find yourself applying those 2 roles often you can wrap them in their own Authorize. This is really an extension of the accepted answer.

using System.Web.Mvc;

public class AuthorizeAdminOrMember : AuthorizeAttribute
{
    public AuthorizeAdminOrMember()
    {
        Roles = "members, admin";
    }
}

And then apply your new authorize to the Action. I think this looks cleaner and reads easily.

public class MyController : Controller
{
    [AuthorizeAdminOrMember]
    public ActionResult MyAction()
    {
        return null;
    }
}

OK, in case you want a normal remote repository, then create an extra branch and check it out. Push it into one branch (which is not checked out) and merge it with one which is currently active later after pushing from locally.

For example, on a remote server:

git branch dev
git checkout dev

On the local setup:

git push 

On remote server:

git merge dev

If your cascading deletes nuke a product because it was a member of a category that was killed, then you've set up your foreign keys improperly. Given your example tables, you should have the following table setup:

CREATE TABLE categories (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE products (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE categories_products (
    category_id int unsigned not null,
    product_id int unsigned not null,
    PRIMARY KEY (category_id, product_id),
    KEY pkey (product_id),
    FOREIGN KEY (category_id) REFERENCES categories (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE,
    FOREIGN KEY (product_id) REFERENCES products (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE
)Engine=InnoDB;

This way, you can delete a product OR a category, and only the associated records in categories_products will die alongside. The cascade won't travel farther up the tree and delete the parent product/category table.

e.g.

products: boots, mittens, hats, coats
categories: red, green, blue, white, black

prod/cats: red boots, green mittens, red coats, black hats

If you delete the 'red' category, then only the 'red' entry in the categories table dies, as well as the two entries prod/cats: 'red boots' and 'red coats'.

The delete will not cascade any farther and will not take out the 'boots' and 'coats' categories.

comment followup:

you're still misunderstanding how cascaded deletes work. They only affect the tables in which the "on delete cascade" is defined. In this case, the cascade is set in the "categories_products" table. If you delete the 'red' category, the only records that will cascade delete in categories_products are those where category_id = red. It won't touch any records where 'category_id = blue', and it would not travel onwards to the "products" table, because there's no foreign key defined in that table.

Here's a more concrete example:

categories:     products:
+----+------+   +----+---------+
| id | name |   | id | name    |
+----+------+   +----+---------+
| 1  | red  |   | 1  | mittens |
| 2  | blue |   | 2  | boots   |
+---++------+   +----+---------+

products_categories:
+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 1          | 2           | // blue mittens
| 2          | 1           | // red boots
| 2          | 2           | // blue boots
+------------+-------------+

Let's say you delete category #2 (blue):

DELETE FROM categories WHERE (id = 2);

the DBMS will look at all the tables which have a foreign key pointing at the 'categories' table, and delete the records where the matching id is 2. Since we only defined the foreign key relationship in products_categories, you end up with this table once the delete completes:

+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 2          | 1           | // red boots
+------------+-------------+

There's no foreign key defined in the products table, so the cascade will not work there, so you've still got boots and mittens listed. There's just no 'blue boots' and no 'blue mittens' anymore.

Run Xampp server.

1. Go to http://localhost which will open up xampp dashboard.

2. Go to PHPInfo link in the top navigation bar.

--- or directly type following url in the browser after run the XAMPP http://localhost/dashboard/phpinfo.php

This will open up php info page. There you can find "Loaded Configuration File /opt/lampp/etc/php.ini" which is the php.ini location.

If you want to pass some random text to your DropDownList, for example --Select-- you can easy do this using this code:

@Html.DropDownListFor(x => x.CategoryId, new SelectList(Model.Categories, "Id", "Name"), "--Select--", new { @class = "form-control" })

I'm a newbie to Python and the offhand comment about Python 3 in the accepted solution was confusing. For posterity, the code to do this in Python 3 is

import urllib.request
data = urllib.request.urlopen(target_url)

for line in data:
    ...

or alternatively

from urllib.request import urlopen
data = urlopen(target_url)

Note that just import urllib does not work.

It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.

I think is because you have try to persist an object that have a reference to another object that is not persist yet, and so it try in the "DB side" to put a reference to a row that not exists

I had the same problem when I was working on asp.net Mvc webApi because cors was not enabled. I solved this by enabling cors inside register method of webApiconfig

First install cors from here then

   public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        var cors = new EnableCorsAttribute("*", "*", "*");
        config.EnableCors(cors);



        config.EnableCors();
        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }

Should be in

Program Files>Microsoft SQL Server>MSSQL 1.0>MSSQL>BACKUP>

In my case it is

C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Backup

If you use the gui or T-SQL you can specify where you want it T-SQL example

BACKUP DATABASE [YourDB] TO  DISK = N'SomePath\YourDB.bak' 
WITH NOFORMAT, NOINIT,  NAME = N'YourDB Full Database Backup', 
SKIP, NOREWIND, NOUNLOAD,  STATS = 10
GO

With T-SQL you can also get the location of the backup, see here Getting the physical device name and backup time for a SQL Server database

SELECT          physical_device_name,
                backup_start_date,
                backup_finish_date,
                backup_size/1024.0 AS BackupSizeKB
FROM msdb.dbo.backupset b
JOIN msdb.dbo.backupmediafamily m ON b.media_set_id = m.media_set_id
WHERE database_name = 'YourDB'
ORDER BY backup_finish_date DESC

I try to set type of column as 'timestamp' and it works for me.

Not exactly in-place, but some idea to do it:

a = ['a', 'b']

def inplace(a):
    c = []
    while len(a) > 0:
        e = a.pop(0)
        if e == 'b':
            c.append(e)
    a.extend(c)

You can extend the function to call you filter in the condition.

You can always add this in any cell:

import pdb; pdb.set_trace()

and the debugger will stop on that line. For example:

In[1]: def fun1(a):
           def fun2(a):
               import pdb; pdb.set_trace() # debugging starts here
           return fun2(a)

In[2]: fun1(1)

Just download & install the following Access DB engine (X86 or X64: as per your machine configuration) and see the magic :)

You can use a simply bind on click and close, like this: (click)="drawer.close()

<a class="nav-link" [routerLink]="navItem.link" routerLinkActive="selected" (click)="drawer.close()">

The answer by Steve Jessop explains well, why you can't use std::map::operator[] on a const std::map. Gabe Rainbow's answer suggests a nice alternative. I'd just like to provide some example code on how to use map::at(). So, here is an enhanced example of your function():

void function(const MAP &map, const std::string &findMe) {
    try {
        const std::string& value = map.at(findMe);
        std::cout << "Value of key \"" << findMe.c_str() << "\": " << value.c_str() << std::endl;
        // TODO: Handle the element found.
    }
    catch (const std::out_of_range&) {
        std::cout << "Key \"" << findMe.c_str() << "\" not found" << std::endl;
        // TODO: Deal with the missing element.
    }
}

And here is an example main() function:

int main() {
    MAP valueMap;
    valueMap["string"] = "abc";
    function(valueMap, "string");
    function(valueMap, "strong");
    return 0;
}

Output:

Value of key "string": abc
Key "strong" not found

I had a similar issue following Firebase's online guide found here.

The section heading "Initialize multiple apps" is misleading as the first example under this heading actually demonstrates how to initialize a single, default app. Here's said example:

// Initialize the default app
var defaultApp = admin.initializeApp(defaultAppConfig);

console.log(defaultApp.name);  // "[DEFAULT]"

// Retrieve services via the defaultApp variable...
var defaultAuth = defaultApp.auth();
var defaultDatabase = defaultApp.database();

// ... or use the equivalent shorthand notation
defaultAuth = admin.auth();
defaultDatabase = admin.database();

If you are migrating from the previous 2.x SDK you will have to update the way you access the database as shown above, or you will get the, No Firebase App '[DEFAULT]' error.

Google has better documentation at the following:

1. INITIALIZE: https://firebase.google.com/docs/database/admin/start

2. SAVE: https://firebase.google.com/docs/database/admin/save-data

3. RETRIEVE: https://firebase.google.com/docs/database/admin/retrieve-data

There is actually a reason behind why all these are messed up. A little more digging deeper is done in this thread and might be helpful to understand the reason why "\\" behaves like this.

.project

When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.

.classpath

Classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.

It is easier to get a stack trace on Firefox than it is on IE but fundamentally here is what you want to do:

Wrap the "problematic" piece of code in a try/catch block:

try {
    // some code that doesn't work
    var t = null;
    var n = t.not_a_value;
}
    catch(e) {
}

If you will examine the contents of the "error" object it contains the following fields:

e.fileName : The source file / page where the issue came from e.lineNumber : The line number in the file/page where the issue arose e.message : A simple message describing what type of error took place e.name : The type of error that took place, in the example above it should be 'TypeError' e.stack : Contains the stack trace that caused the exception

I hope this helps you out.

As Chris suggested the reason you're using ViewModel doesn't stop you from using PagedList. You need to form a collection of your ViewModel objects that needs to be send to the view for paging over.

Here is a step by step guide on how you can use PagedList for your viewmodel data.

Your viewmodel (I have taken a simple example for brevity and you can easily modify it to fit your needs.)

public class QuestionViewModel
{
        public int QuestionId { get; set; }
        public string QuestionName { get; set; }
}

and the Index method of your controller will be something like

public ActionResult Index(int? page)
{
     var questions = new[] {
           new QuestionViewModel { QuestionId = 1, QuestionName = "Question 1" },
           new QuestionViewModel { QuestionId = 1, QuestionName = "Question 2" },
           new QuestionViewModel { QuestionId = 1, QuestionName = "Question 3" },
           new QuestionViewModel { QuestionId = 1, QuestionName = "Question 4" }
     };

     int pageSize = 3;
     int pageNumber = (page ?? 1);
     return View(questions.ToPagedList(pageNumber, pageSize));
}

And your Index view

@model PagedList.IPagedList<ViewModel.QuestionViewModel>
@using PagedList.Mvc; 
<link href="/Content/PagedList.css" rel="stylesheet" type="text/css" />


<table>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.QuestionId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.QuestionName)
        </td>
    </tr>
}

</table>

<br />

Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount
@Html.PagedListPager( Model, page => Url.Action("Index", new { page }) )

The answer is here: How to use C/Cpp extension and add includepath to configurations.

Click the light bulb and then edit the JSON file which is opened. Choose the right block corresponding to your platform (there are Mac, Linux, Win32 – ms-vscode.cpptools version: 3). Update paths in includePath (matters if you compile with VS Code) or browse.paths (matters if you navigate with VS Code) or both.

Thanks to @Francesco Borzì, I will append his answer here:

You have to Left click on the bulb next to the squiggled code line.

Edit your .bowerrc file ( should be next to your bower.json file ) and add the wanted proxy configuration

"proxy":"http://<host>:<port>",
"https-proxy":"http://<host>:<port>"

There are different ways to measure the height depending on what you need.

getTextBounds

If you are doing something like precisely centering a small amount of fixed text, you probably want getTextBounds. You can get the bounding rectangle like this

Rect bounds = new Rect();
mTextPaint.getTextBounds(mText, 0, mText.length(), bounds);
int height = bounds.height();

As you can see for the following images, different strings will give different heights (shown in red).

These differing heights could be a disadvantage in some situations when you just need a constant height no matter what the text is. See the next section.

Paint.FontMetrics

You can calculate the hight of the font from the font metrics. The height is always the same because it is obtained from the font, not any particular text string.

Paint.FontMetrics fm = mTextPaint.getFontMetrics();
float height = fm.descent - fm.ascent;

The baseline is the line that the text sits on. The descent is generally the furthest a character will go below the line and the ascent is generally the furthest a character will go above the line. To get the height you have to subtract ascent because it is a negative value. (The baseline is y=0 and y descreases up the screen.)

Look at the following image. The heights for both of the strings are 234.375.

If you want the line height rather than just the text height, you could do the following:

float height = fm.bottom - fm.top + fm.leading; // 265.4297

These are the bottom and top of the line. The leading (interline spacing) is usually zero, but you should add it anyway.

The images above come from this project. You can play around with it to see how Font Metrics work.

StaticLayout

For measuring the height of multi-line text you should use a StaticLayout. I talked about it in some detail in this answer, but the basic way to get this height is like this:

String text = "This is some text. This is some text. This is some text. This is some text. This is some text. This is some text.";

TextPaint myTextPaint = new TextPaint();
myTextPaint.setAntiAlias(true);
myTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
myTextPaint.setColor(0xFF000000);

int width = 200;
Layout.Alignment alignment = Layout.Alignment.ALIGN_NORMAL;
float spacingMultiplier = 1;
float spacingAddition = 0;
boolean includePadding = false;

StaticLayout myStaticLayout = new StaticLayout(text, myTextPaint, width, alignment, spacingMultiplier, spacingAddition, includePadding);

float height = myStaticLayout.getHeight(); 

NOTE: This answer is from 2011. It was a really good answer back then, but as of 2015, native HTML properties are supported by most browsers, so there's (usually) no need to implement such custom logic in JS. See Edi's answer and the docs.

Before the file is uploaded, you can check the file's extension using Javascript, and prevent the form being submitted if it doesn't match. The name of the file to be uploaded is stored in the "value" field of the form element.

Here's a simple example that only allows files that end in ".gif" to be uploaded:

<script type="text/javascript">
    function checkFile() {
        var fileElement = document.getElementById("uploadFile");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension.toLowerCase() == "gif") {
            return true;
        }
        else {
            alert("You must select a GIF file for upload");
            return false;
        }
    }
</script>

<form action="upload.aspx" enctype="multipart/form-data" onsubmit="return checkFile();">
    <input name="uploadFile" id="uploadFile" type="file" />

    <input type="submit" />
</form>

However, this method is not foolproof. Sean Haddy is correct that you always want to check on the server side, because users can defeat your Javascript checking by turning off javascript, or editing your code after it arrives in their browser. Definitely check server-side in addition to the client-side check. Also I recommend checking for size server-side too, so that users don't crash your server with a 2 GB file (there's no way that I know of to check file size on the client side without using Flash or a Java applet or something).

However, checking client side before hand using the method I've given here is still useful, because it can prevent mistakes and is a minor deterrent to non-serious mischief.

There is some flickering problem in {{ }} like when you refresh the page then for a short spam of time expression is seen.So we should use ng-bind instead of expression for data depiction.

NOLOCK makes most SELECT statements faster, because of the lack of shared locks. Also, the lack of issuance of the locks means that writers will not be impeded by your SELECT.

NOLOCK is functionally equivalent to an isolation level of READ UNCOMMITTED. The main difference is that you can use NOLOCK on some tables but not others, if you choose. If you plan to use NOLOCK on all tables in a complex query, then using SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED is easier, because you don't have to apply the hint to every table.

Here is information about all of the isolation levels at your disposal, as well as table hints.

Another solution not mentioned yet is by hooking the Writable streams in process.stdout and process.stderr. This way you don't need to override all the console functions that output to stdout and stderr. This implementation redirects both stdout and stderr to a log file:

var log_file = require('fs').createWriteStream(__dirname + '/log.txt', {flags : 'w'})

function hook_stream(stream, callback) {
    var old_write = stream.write

    stream.write = (function(write) {
        return function(string, encoding, fd) {
            write.apply(stream, arguments)  // comments this line if you don't want output in the console
            callback(string, encoding, fd)
        }
    })(stream.write)

    return function() {
        stream.write = old_write
    }
}

console.log('a')
console.error('b')

var unhook_stdout = hook_stream(process.stdout, function(string, encoding, fd) {
    log_file.write(string, encoding)
})

var unhook_stderr = hook_stream(process.stderr, function(string, encoding, fd) {
    log_file.write(string, encoding)
})

console.log('c')
console.error('d')

unhook_stdout()
unhook_stderr()

console.log('e')
console.error('f')

It should print in the console

a
b
c
d
e
f

and in the log file:

c
d

Here is the code (but not in C#):

Public ReadOnly Property CurrentUser As String
    Get
        If String.IsNullOrEmpty(m_CurUser) Then
            Dim who As System.Security.Principal.IIdentity = System.Security.Principal.WindowsIdentity.GetCurrent()

            If who Is Nothing Then
                m_CurUser = Environment.UserDomainName & "\" & Environment.UserName
            Else
                m_CurUser = who.Name
            End If
        End If
        Return m_CurUser
    End Get

In my case, I was on CentOS 7 and my php installation was pointing to a certificate that was being generated through update-ca-trust. The symlink was /etc/pki/tls/cert.pem pointing to /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem. This was just a test server and I wanted my self signed cert to work properly. So in my case...

# My root ca-trust folder was here. I coped the .crt file to this location
# and renamed it to a .pem
/etc/pki/ca-trust/source/anchors/self-signed-cert.pem

# Then run this command and it will regenerate the certs for you and
# include your self signed cert file.
update-ca-trust

Then some of my api calls started working as my cert was now trusted. Also if your ca-trust gets updated through yum or something, this will rebuild your root certificates and still include your self signed cert. Run man update-ca-trust for more info on what to do and how to do it. :)

1. You can remove brackets and line breaks.

if (city.getName() != null) name = city.getName(); else name = "N/A";

2. You can use ?: operators in java.

Syntax:

Variable = Condition ? BlockTrue : BlockElse;

So in your code you can do like this:

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

3. Assign condition result for Boolean

boolean hasName = city.getName() != null;

EXTRA: for curious

In some languages based in JAVA like Groovy, you can use this syntax:

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

The operator ?: assign the value returned from the variable which we are asking for. In this case, the value of city.getName() if it's not null.

You can use the username variable: %USERNAME%

ButterKnife is probably the best solution for the clutter problem. It uses annotation processors to generate the so called "old method" boilerplate code.

But the onClick method can still be used, with a custom inflator.

How to use

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup cnt, Bundle state) {
    inflater = FragmentInflatorFactory.inflatorFor(inflater, this);
    return inflater.inflate(R.layout.fragment_main, cnt, false);
}

Implementation

public class FragmentInflatorFactory implements LayoutInflater.Factory {

    private static final int[] sWantedAttrs = { android.R.attr.onClick };

    private static final Method sOnCreateViewMethod;
    static {
        // We could duplicate its functionallity.. or just ignore its a protected method.
        try {
            Method method = LayoutInflater.class.getDeclaredMethod(
                    "onCreateView", String.class, AttributeSet.class);
            method.setAccessible(true);
            sOnCreateViewMethod = method;
        } catch (NoSuchMethodException e) {

An EXC_BAD_ACCESS signal is the result of passing an invalid pointer to a system call. I got one just earlier today with a test program on OS X - I was passing an uninitialized variable to pthread_join(), which was due to an earlier typo.

I'm not familiar with iPhone development, but you should double-check all your buffer pointers that you're passing to system calls. Crank up your compiler's warning level all the way (with gcc, use the -Wall and -Wextra options). Enable as many diagnostics on the simulator/debugger as possible.

show alert box with use variable with message

<script>
$(document).ready(function() {
var total = 30 ;
alert("your total is :"+ total +"rs");
});
</script>

Here is a minimal example of how @property can be implemented:

class Thing:
    def __init__(self, my_word):
        self._word = my_word 
    @property
    def word(self):
        return self._word

>>> print( Thing('ok').word )
'ok'

Otherwise word remains a method instead of a property.

class Thing:
    def __init__(self, my_word):
        self._word = my_word
    def word(self):
        return self._word

>>> print( Thing('ok').word() )
'ok'

Define an interface, and implement it in the class that will receive the callback.

Have attention to the multi-threading in your case.

Code example from http://cleancodedevelopment-qualityseal.blogspot.com.br/2012/10/understanding-callbacks-with-java.html

interface CallBack {                   //declare an interface with the callback methods, so you can use on more than one class and just refer to the interface
    void methodToCallBack();
}

class CallBackImpl implements CallBack {          //class that implements the method to callback defined in the interface
    public void methodToCallBack() {
        System.out.println("I've been called back");
    }
}

class Caller {

    public void register(CallBack callback) {
        callback.methodToCallBack();
    }

    public static void main(String[] args) {
        Caller caller = new Caller();
        CallBack callBack = new CallBackImpl();       //because of the interface, the type is Callback even thought the new instance is the CallBackImpl class. This alows to pass different types of classes that have the implementation of CallBack interface
        caller.register(callBack);
    }
} 

In your case, apart from multi-threading you could do like this:

interface ServerInterface {
    void newSeverConnection(Socket socket);
}

public class Server implements ServerInterface {

    public Server(int _address) {
        System.out.println("Starting Server...");
        serverConnectionHandler = new ServerConnections(_address, this);
        workers.execute(serverConnectionHandler);
        System.out.println("Do something else...");
    }

    void newServerConnection(Socket socket) {
        System.out.println("A function of my child class was called.");
    }

}

public class ServerConnections implements Runnable {

    private ServerInterface serverInterface;

    public ServerConnections(int _serverPort, ServerInterface _serverInterface) {
      serverPort = _serverPort;
      serverInterface = _serverInterface;
    }

    @Override
    public void run() {
        System.out.println("Starting Server Thread...");

        if (serverInterface == null) {
            System.out.println("Server Thread error: callback null");
        }

        try {
            mainSocket = new ServerSocket(serverPort);

            while (true) {
                serverInterface.newServerConnection(mainSocket.accept());
            }
        } catch (IOException ex) {
            Logger.getLogger(Server.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

Multi-threading

Remember this does not handle multi-threading, this is another topic and can have various solutions depending on the project.

The observer-pattern

The observer-pattern does nearly this, the major difference is the use of an ArrayList for adding more than one listener. Where this is not needed, you get better performance with one reference.

The problem is with percentage sizing. You are not defining the size of the parent div (the new one), so the browser can not report the size to the Google Maps API. Giving the wrapper div a specific size, or a percentage size if the size of its parent can be determined, will work.

See this explanation from Mike Williams' Google Maps API v2 tutorial:

If you try to use style="width:100%;height:100%" on your map div, you get a map div that has zero height. That's because the div tries to be a percentage of the size of the <body>, but by default the <body> has an indeterminate height.

There are ways to determine the height of the screen and use that number of pixels as the height of the map div, but a simple alternative is to change the <body> so that its height is 100% of the page. We can do this by applying style="height:100%" to both the <body> and the <html>. (We have to do it to both, otherwise the <body> tries to be 100% of the height of the document, and the default for that is an indeterminate height.)

Add the 100% size to html and body in your css

    html, body, #map-canvas {
        margin: 0;
        padding: 0;
        height: 100%;
        width: 100%;
    }

Add it inline to any divs that don't have an id:

<body>
  <div style="height:100%; width: 100%;"> 
    <div id="map-canvas"></div>
  </div>
</body>

this issue can be resolved using 2 ways:

1. Kill application running on 8080

netstat -ao | find "8080"

Taskkill /PID 1342 /F

2. change spring server port in application.properties file

server.port=8081

If the assertion is false, the message is displayed. Specifically, if the first argument is false, the second argument (the string message) will be be logged in the developer tools console. If the first argument is true, basically nothing happens. A simple example – I’m using Google Developer Tools:

var isTrue = true;
var isFalse = false;
console.assert(isTrue, 'Equals true so will NOT log to the console.');
console.assert(isFalse, 'Equals false so WILL log to the console.');

You can use VLOOKUP, but this requires a wrapper function to return True or False. Not to mention it is (relatively) slow. Use COUNTIF or MATCH instead.

Fill down this formula in column K next to the existing values in column I (from I1 to I2691):

=COUNTIF(<entire column E range>,<single column I value>)>0
=COUNTIF($E$1:$E$99504,$I1)>0

You can also use MATCH:

=NOT(ISNA(MATCH(<single column I value>,<entire column E range>)))
=NOT(ISNA(MATCH($I1,$E$1:$E$99504,0)))

ansible -m setup hostname

Only gets the facts gathered by the setup module.

Gilles Cornu posted a template trick to list all variables for a specific host.

Template (later called dump_variables):

HOSTVARS (ANSIBLE GATHERED, group_vars, host_vars) :

{{ hostvars[inventory_hostname] | to_yaml }}

PLAYBOOK VARS:

{{ vars | to_yaml }}

Playbook to use it:

- hosts: all
  tasks:
  - template:
      src: templates/dump_variables
      dest: /tmp/ansible_variables
  - fetch:
      src: /tmp/ansible_variables
      dest: "{{inventory_hostname}}_ansible_variables"

After that you have a dump of all variables on every host, and a copy of each text dump file on your local workstation in your tmp folder. If you don't want local copies, you can remove the fetch statement.

This includes gathered facts, host variables and group variables. Therefore you see ansible default variables like group_names, inventory_hostname, ansible_ssh_host and so on.

my simple JavaScript library called FuncJS has a function called "strip_tags()" which does the task for you — without requiring you to enter any regular expressions.

For example, say that you want to remove tags from a sentence - with this function, you can do it simply like this:

strip_tags("This string <em>contains</em> <strong>a lot</strong> of tags!");

This will produce "This string contains a lot of tags!".

For a better understanding, please do read the documentation at GitHub FuncJS.

Additionally, if you'd like, please provide some feedback through the form. It would be very helpful to me!

It is a class that extends another class.

example taken from https://www.java-tips.org/java-se-tips-100019/24-java-lang/784-what-is-a-java-subclass.html, Cat is a sub class of Animal :-)

public class Animal {

    public static void hide() {
        System.out.println("The hide method in Animal.");
    }

    public void override() {
        System.out.println("The override method in Animal.");
    }
}

public class Cat extends Animal {

    public static void hide() {
        System.out.println("The hide method in Cat.");
    }

    public void override() {
        System.out.println("The override method in Cat.");
    }

    public static void main(String[] args) {
        Cat myCat = new Cat();
        Animal myAnimal = (Animal)myCat;
        myAnimal.hide();
        myAnimal.override();
    }
}

Tomcat 8 : After many searches this is only working code: in server.xml

<!-- Set /apple as default path -->
    <Host name="localhost"  appBase="webapps"
         unpackWARs="true" autoDeploy="true">
     <Context path="" docBase="apple">
         <!-- Default set of monitored resources -->
         <WatchedResource>WEB-INF/web.xml</WatchedResource>
     </Context>
    </Host>

Restart Tomcat, make sure when you access 127.0.0.1:8080, it will display the content in 127.0.0.1:8080/apple

My project was java web application witch created by netbeans ,I set context path in project configuration, no other thing, even I put apple.war in webapps folder.

If you want to change the session id on each log in, make sure to use session_regenerate_id(true) during the log in process.

<?php
session_start();
session_regenerate_id(true);
?> 

mp3 files sometimes throw strange mime types as per this answer: https://stackoverflow.com/a/2755288/14482130

If you are doing some user validation do not allow 'application/octet-stream' or 'application/x-zip-compressed' as suggested above since they can contain be .exe or other potentially dangerous files.

In order to validate when mime type gives a false negative you can use fleep as per this answer https://stackoverflow.com/a/52570299/14482130 to finish the validation.

The best answer I use to receive data from server and display it

 constructor(props){
            super(props);
            this.state = {
                items2 : [{}],
                isLoading: true
            }

        }

componentWillMount (){
 axios({
            method: 'get',
            responseType: 'json',
            url: '....',

        })
            .then(response => {
                self.setState({
                    items2: response ,
                    isLoading: false
                });
                console.log("Asmaa Almadhoun *** : " + self.state.items2);
            })
            .catch(error => {
                console.log("Error *** : " + error);
            });
    })}



    render() {
       return(
       { this.state.isLoading &&
                    <i className="fa fa-spinner fa-spin"></i>

                }
                { !this.state.isLoading &&
            //external component passing Server data to its classes
                     <TestDynamic  items={this.state.items2}/> 
                }
         ) }

Kotlin for XML

app:cardBackgroundColor="@android:color/red"

code

cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));

You can use issubclass() like this assert issubclass(suit, Suit).

add class inside oncreate() method

 setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

I am using httpclient 4.4.

For solr query I used the following way and it worked.

NameValuePair nv2 = new BasicNameValuePair("fq","(active:true) AND (category:Fruit OR category1:Vegetable)");
nvPairList.add(nv2);
NameValuePair nv3 = new BasicNameValuePair("wt","json");
nvPairList.add(nv3);
NameValuePair nv4 = new BasicNameValuePair("start","0");
nvPairList.add(nv4);
NameValuePair nv5 = new BasicNameValuePair("rows","10");
nvPairList.add(nv5);

HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(url);
URI uri = new URIBuilder(request.getURI()).addParameters(nvPairList).build();
            request.setURI(uri);

HttpResponse response = client.execute(request);    
if (response.getStatusLine().getStatusCode() != 200) {

}

BufferedReader br = new BufferedReader(
                             new InputStreamReader((response.getEntity().getContent())));

String output;
System.out.println("Output  .... ");
String respStr = "";
while ((output = br.readLine()) != null) {
    respStr = respStr + output;
    System.out.println(output);
}

You can also run this:

php artisan migrate:status

It makes a db connection connection to get migrations from migrations table. It'll throw an exception if the connection fails.

Write-through: Write is done synchronously both to the cache and to the backing store.

Write-back (or Write-behind): Writing is done only to the cache. A modified cache block is written back to the store, just before it is replaced.

Write-through: When data is updated, it is written to both the cache and the back-end storage. This mode is easy for operation but is slow in data writing because data has to be written to both the cache and the storage.

Write-back: When data is updated, it is written only to the cache. The modified data is written to the back-end storage only when data is removed from the cache. This mode has fast data write speed but data will be lost if a power failure occurs before the updated data is written to the storage.

There is also a smaller one yet called "input-mini".

Marknote is a nice lightweight cross-browser JavaScript XML parser. It's object-oriented and it's got plenty of examples, plus the API is documented. It's fairly new, but it has worked nicely in one of my projects so far. One thing I like about it is that it will read XML directly from strings or URLs and you can also use it to convert the XML into JSON.

Here's an example of what you can do with Marknote:

var str = '<books>' +
          '  <book title="A Tale of Two Cities"/>' +
          '  <book title="1984"/>' +
          '</books>';

var parser = new marknote.Parser();
var doc = parser.parse(str);

var bookEls = doc.getRootElement().getChildElements();

for (var i=0; i<bookEls.length; i++) {
    var bookEl = bookEls[i];
    // alerts "Element name is 'book' and book title is '...'"
    alert("Element name is '" + bookEl.getName() + 
        "' and book title is '" + 
        bookEl.getAttributeValue("title") + "'"
    );
}

Try this:

subset(studentdata, Drink=='water')

that should do it.

You can print in simple way.

Use below to print 2D array

int[][] array = new int[rows][columns];
System.out.println(Arrays.deepToString(array));

Use below to print 1D array

int[] array = new int[size];
System.out.println(Arrays.toString(array));

In [6]: x = -2
In [7]: x
Out[7]: -2

In [8]: abs(x)
Out[8]: 2

Actually abs will return the absolute value of any number. Absolute value is always a non-negative number.
