This issue is due to incompatible of your plugin Verison and required Gradle version; they need to match with each other. I am sharing how my problem was solved.

plugin version

Required Gradle version is here

more compatibility you can see from here. Android Plugin for Gradle Release Notes

if you have the android studio version 4.0.1

then your top level gradle file must be like this

buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.2'
    classpath 'com.google.firebase:firebase-crashlytics-gradle:2.4.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

and the gradle version should be

and your app gradle look like this

This is a popular question. If you do not use these methods, the solution is updating the libraries. Please update your kotlin version, and all your dependencies like fabric, protobuf etc. If you are sure that you have updated everything, try asking the author of the library.

Google has introduced new AndroidX dependencies. You need to migrate to AndroidX, it's simple.

I replaced all dependencies to AndroidX dependencies

Old design dependency

implementation 'com.android.support:design:28.0.0'

New AndroidX design dependency

implementation 'com.google.android.material:material:1.0.0-rc01'

you can find AndroidX dependencies here https://developer.android.com/jetpack/androidx/migrate

Automatic AndroidX migration option (supported on android studio 3.3+)

Migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

If you receive an error stating the library cannot be found, check the Google maven repo for your library and version. I had a version suddenly disappear and make my builds fail.

https://maven.google.com/web/index.html

Changed all dependencies to compile rather than implementation, then I rebuild the project without errors. Then I switched back to implementation rather than leaving it as compile.

If you are building DEBUG APK, just add:

debug {
            multiDexEnabled true
        }

inside buildTypes

and if you are building RELEASE APK, add multiDexEnabled true in release block as-

release {
                ...
                multiDexEnabled true
                ...
        }

I found the solution as Its problem with Android Studio 3.1 Canary 6

My backup of Android Studio 3.1 Canary 5 is useful to me and saved my half day.

Now My build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.2'
    defaultConfig {
        applicationId "com.example.demo"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    dataBinding {
        enabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:design:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:support-v4:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:recyclerview-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:cardview-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.squareup.retrofit2:retrofit:2.3.0"
    implementation "com.google.code.gson:gson:2.8.2"
    implementation "com.android.support.constraint:constraint-layout:1.0.2"
    implementation "com.squareup.retrofit2:converter-gson:2.3.0"
    implementation "com.squareup.okhttp3:logging-interceptor:3.6.0"
    implementation "com.squareup.picasso:picasso:2.5.2"
    implementation "com.dlazaro66.qrcodereaderview:qrcodereaderview:2.0.3"
    compile 'com.github.elevenetc:badgeview:v1.0.0'
    annotationProcessor 'com.github.elevenetc:badgeview:v1.0.0'
    testImplementation "junit:junit:4.12"
    androidTestImplementation("com.android.support.test.espresso:espresso-core:3.0.1", {
        exclude group: "com.android.support", module: "support-annotations"
    })
}

and My gradle is:

classpath 'com.android.tools.build:gradle:3.1.0-alpha06'

and its working finally.

I think there problem in Android Studio 3.1 Canary 6

Thank you all for your time.

possible issue related to this can be with your XML files. I have faced this when I deleted my unnecery xml files.

For remedy from this error in gradle.properties of the module, add this below line:

android.enableAapt2=false

after adding this line, restart the gradle.

and do once clean, rebuild your project.

Your android studio may be forgot to put : buildToolsVersion "26.0.0" you need 'buildTools' to develop related design and java file. And if there is no any buildTools are installed in Android->sdk->build-tools directory then download first.

Find root build.gradle file and add google maven repo inside allprojects tag

repositories {
        mavenLocal()
        mavenCentral()
        maven {                                  // <-- Add this
            url 'https://maven.google.com/' 
            name 'Google'
        }
    } 

It's better to use specific version instead of variable version

compile 'com.android.support:appcompat-v7:27.0.0'

If you're using Android Plugin for Gradle 3.0.0 or latter version

repositories {
      mavenLocal()
      mavenCentral()
      google()        //---> Add this
} 

and inject dependency in this way :

implementation 'com.android.support:appcompat-v7:27.0.0'

Simply try doing a "Build -> Clean Project". That solved the problem for me.

Make sure all same source library have same version number. In my case I was using different google api versions. I was using 11.6.0 for all google libraries but 10.4.0 for google place api. After updating google place api to 11.6.0, problem fixed.

Please note that my multidex is also enabled for the project.

angular 5 :

 getImage(id: string): Observable<Blob> {
    return this.httpClient.get('http://myip/image/'+id, {responseType: "blob"});
}

If you already use jitpack.io or any repository. You can add google repository like this:

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
        maven { url "https://maven.google.com" }
    }
}

See in your library projects make the compileSdkVersion and targetSdkVersion version to same level as your application is

android {
    compileSdkVersion 28

    defaultConfig {
        consumerProguardFiles 'proguard-rules.txt'
        minSdkVersion 14
        targetSdkVersion 28
    }
}

also make all dependencies to same level

you must add in your MODULE-LEVEL build.gradle file with:

//module-level build.gradle file
repositories {
    maven {
        url 'https://maven.google.com'

    }
}

see: Google's Maven repository

I have observed that when I use Android Studio 2.3.3 I MUST add repositories{maven{url 'https://maven.google.com'}} in MODULE-LEVEL build.gradle. In the case of Android Studio 3.0.0 there is no need for the addition in module-level build.gradle. It is enough the addition in project-level build.gradle which has been referred to in the other posts here, namely:

//project-level build.gradle file
allprojects {
 repositories {
    jcenter()
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
  }
}

UPDATE 11-14-2017: The solution, that I present, was valid when I did the post. Since then, there have been various updates (even with respect to the site I refer to), and I do not know if now is valid. For one month I did my work depending on the solution above, until I upgraded to Android Studio 3.0.0

Try to remove multidex from default config and check the build error log. If that log is some relatable with INotification class. Use this in android{}

configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

This helps me.

Just Change the Distribution url at gradle-wrapper.properties

Place it : https://services.gradle.org/distributions/gradle-4.10.1-all.zip

I got such error after a simple try of code refactoring. It has happened nor after some library was connected neither any changes in gradle. It looked like something in my code was wrong but the compiler could not found the issue. That's why I double checked all changes that I did and found that I had changed somehow method signature in the interface but had not changed it in class that implements it. I got this error twice during one day and decided to share my experience. I hope that it is a temporary compiler bug.

Solution 1 Possible solution is to go to File -> Settings -> Compiler -> and add "--stacktrace --debug" to Command-line Options. Read log and try to found the answer of what went wrong.

In new Android Studio 3.1.+, you can enable/disable console log details by pressing "Toggle View" on "Build" tab. There you can find the details. Pay attention that both modes can be useful for investigation of the problem's reason. See: https://stackoverflow.com/a/49717363/

Solution 2 Click on Gradle (on the right side bar) then under :app choose assembleDebug (or assembleYourFlavor if you use flavors). Error will show up in Run tab. See: https://stackoverflow.com/a/51022296

Solution 3 As a last resort. In the android studio, try Analyze -> Inspect Code -> Whole project. Wait until the inspection is over and then correct errors in "General" section and possible ones in other sections.

Note The kapt3 can be a source of such bugs. I removed apply plugin: 'kotlin-kapt' and added kapt { generateStubs = true } into android {} section of build.gradle. It seems that the previous version of the kapt generator is bugs free. (Update. It looks like a bug with kapt is gone on kotlin version 1.2.+)

Open gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

change it to

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

Import your company certificate at Tools->Android->SDK Manager->Tools->Server Certificates

Solution for me (Android Studio) :

1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure

2) and increase the level of SDK "Compile SDK Version".

I'm not sure about you, but I spent about 30 minutes troubleshooting the same issue here, until I realized that the line for app/build.gradle is:

apply plugin: 'com.google.gms.google-services'

and not:

apply plugin: 'com.google.gms:google-services'

Eg: I had copied that line from a tutorial, but when specifying the apply plugin namespace, no colon (:) is required. It's, in fact, a dot. (.).

Hey... it's easy to miss.

I had the same error and I solved it with MultiDex, like described on this link : https://developer.android.com/studio/build/multidex.html

Sometimes it is not enough just to enable MultiDex.

If any class that's required during startup is not provided in the primary DEX file, then your app crashes with the error java.lang.NoClassDefFoundError. https://developer.android.com/studio/build/multidex#keep

FirebaseInitProvider is required during startup.

So you must manually specify FirebaseInitProvider as required in the primary DEX file.

build.gradle file

android {
    buildTypes {
        release {
            multiDexKeepFile file('multidex-config.txt')
            ...
        }
    }
}

multidex-config.txt (in the same directory as the build.gradle file)

com/google/firebase/provider/FirebaseInitProvider.class

There are multiple possible causes for this error:

1) When you put the property 'x' inside brackets you are trying to bind to it. Therefore first thing to check is if the property 'x' is defined in your component with an Input() decorator

Your html file:

<body [x]="...">

Your class file:

export class YourComponentClass {

  @Input()
  x: string;
  ...
}

(make sure you also have the parentheses)

2) Make sure you registered your component/directive/pipe classes in NgModule:

@NgModule({
  ...
  declarations: [
    ...,
    YourComponentClass
  ],
  ...
})

See https://angular.io/guide/ngmodule#declare-directives for more details about declare directives.

3) Also happens if you have a typo in your angular directive. For example:

<div *ngif="...">
     ^^^^^

Instead of:

<div *ngIf="...">

This happens because under the hood angular converts the asterisk syntax to:

<div [ngIf]="...">

Actually you have a code compiled targeting a higher JDK (JDK 1.8 in your case) but at runtime you are supplying a lower JRE(JRE 7 or below).

you can fix this problem by adding target parameter while compilation
e.g. if your runtime target is 1.7, you should use 1.7 or below

javac -target 1.7 *.java

if you are using eclipse, you can sent this parameter at Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" = choose your runtime jre version or lower.

Well in my case i was accessing an static array of a class by reference of that class, but as we know we can directly access static member via class name. So when I replaced reference with class name where I was accessing that array. It fixed this error.

My Settings Screenshot:

Thanks to this post.

Just turn off instant run in your settings. You can easily search the keyword "instant" like I showed and it would switch to the window you want.

From Gradle Plugin User Guide:

When instrumentation tests are run, both the main APK and test APK share the same classpath. Gradle build will fail if the main APK and the test APK use the same library (e.g. Guava) but in different versions. If gradle didn't catch that, your app could behave differently during tests and during normal run (including crashing in one of the cases).

To make the build succeed, just make sure both APKs use the same version. If the error is about an indirect dependency (a library you didn't mention in your build.gradle), just add a dependency for the newer version to the configuration

Add this line to your build.gradle dependencies to use newer version for both APKs:

compile('com.google.code.findbugs:jsr305:2.0.1')

For future reference, you can check your Gradle Console and it will provide a helpful link next to the error to help with any gradle build errors.

Feb 25th 2021:

For me, after over 8 hours of trials and errors, it was the re-ordering of the repositories sources in the project-level build.gradle file that solved the issue for me. So, instead of:

buildscript {
  ...
  repositories {
        google()
        mavenCentral()
        maven { url "https://plugins.gradle.org/m2/" }
  }
  ...
}

I moved google() to the bottom:

buildscript {
  ...
  repositories {
        mavenCentral()
        maven { url "https://plugins.gradle.org/m2/" }
        google()
  }
  ...
}

Of course, be sure to update the gradle android plugin and the matching gradle-wrapper distribution versions too.

TL;DR: Check the path to your keystore.jks file.

In my case, here's what happened:

I moved the project folder of my entire app to another location on my PC. Much later, I wanted to generate a signed apk file. Unknown to me, the default location of the path to my keystore.jks had been reset to a wrong location and I had clicked okay. Since it could not find a keystore at the path I selected, I got that error.

The solution was to check whether the path to my keystore.jks file was correct.

I am having random issues with the latest AndroidStudio (3.2 B1) and tried all the solutions above. I got it working by disabling the "Zip Align Enabled" option in "Build Types"

Just migrate to Androidx as shown above and then set teh minimum sdk version to 26...with no doubts this works perfectly

Stopping OpenSdk Java process (inner to Android Studio process) worked.

This just happened to me. It turned out I was requesting ALL permissions, when I needed to filter to just DANGEROUS permissions, and it suddenly started working.

fun requestPermissions() {
    val missingDangerPermissions = PERMISSIONS
            .filter { ContextCompat.checkSelfPermission(this, it) != PackageManager.PERMISSION_GRANTED }
            .filter { this.getPackageManager().getPermissionInfo(it, PackageManager.GET_META_DATA).protectionLevel == PermissionInfo.PROTECTION_DANGEROUS } // THIS FILTER HERE!

    if (missingDangerPermissions.isNotEmpty()) {
        Log.i(TAG, "Requesting dangerous permission to $missingDangerPermissions.")
        ActivityCompat.requestPermissions(this,
                missingDangerPermissions.toTypedArray(),
                REQUEST_CODE_REQUIRED_PERMISSIONS);
        return
    } else {
        Log.i(TAG, "We had all the permissions we needed (yay!)")
    }
}

Open android/gradle/gradle-wrapper.properties and change this line: distributionUrl=

https\://services.gradle.org/distributions/gradle-4.1-all.zip

to this line:

distributionUrl=

https\://services.gradle.org/distributions/gradle-4.4-all.zip

Open android/build.gradle and change this line:

classpath 'com.android.tools.build:gradle:3.0.1'

to this:

classpath 'com.android.tools.build:gradle:3.1.2'

Keypoint

Your layout name is in snake_case.

activity_login.xml

Then your binding class name will be in CamelCase.

ActivityLoginBinding.java

Also build project after creating layout. Sometimes it is not generated automatically.

also try to increase gradle version in your project's build.gradle. It helped me

check that, in your "google-services.json" file your package_name is available or not

You can run this command in your project directory. Basically it just cleans the build and gradle.

   cd android && rm -R .gradle && cd app && rm -R build

In my case, I was using react-native using this as a script in package.json

"scripts": { "clean-android": "cd android && rm -R .gradle && cd app && rm -R build" }

Try

dexOptions {
    javaMaxHeapSize "4g"
    preDexLibraries = false
}

I don't know the reason. Something about preDexLibraries : https://sites.google.com/a/android.com/tools/tech-docs/new-build-system/tips

According to @lgdroid57 :

The following resource should help explain what this code does: link(http://google.github.io/android-gradle-dsl/current/com.android.build.gradle.internal.dsl.DexOptions.html) Property | Description javaMaxHeapSize | Sets the -JXmx* value when calling dx. Format should follow the 1024M pattern. preDexLibraries | Whether to pre-dex libraries. This can improve incremental builds, but clean builds may be slower.

check gradle.properties and add android.useAndroidX=true or you can also add android.enableJetifier=true or you can comment it by #

worked for me

Update: Does not apply to the Android Studio released after this answer (April 2016)

Note: I think this might be a bug in Android Studio.

1. Go to Project Structure
2. Select App Module
3. Under the first tab "Properties" change the Compile SDK Version to API XX from Google API xx (e.g. API 23 instead of Google API 23)
4. Press OK
5. Wait for the completion of on going process, in my case I did not get an error at this point.

Now revert Compiled Sdk Version back to Google API xx.

If this not work, then:

6. With Google API (Google API xx instead of API xx), lower the build tool version (e.g. Google API 23 and build tool version 23.0.1)
7. Press Ok and wait for completion of on going process
8. Revert back your build tool version to what it was before you changed
9. Press Ok
10. Wait for the completion of process.
11. Done!

In Android Studio open: File > Project Structure and check if JDK location points to your JDK 1.8 directory.

Note: you can use compileSdkVersion 24. It works trust me. For this to work first download latest JDK from Oracle.

All the above not working for me.. Because I am using Facebook Ad dependency..

Incase If anybody using this dependency compile 'com.facebook.android:audience-network-sdk:4.16.0'

Try this code instead of above

compile ('com.facebook.android:audience-network-sdk:4.16.0'){
exclude group: 'com.google.android.gms'
}

please add these codes to your dependencies. It will work.

implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    implementation 'com.android.support:appcompat-v7:23.1.0'
    implementation 'com.android.support:design:23.1.0'
    implementation 'com.android.support:cardview-v7:23.1.0'
    implementation 'com.android.support:recyclerview-v7:23.1.0'

    implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}

Just connect to Internet and start Android Studio and open your project. While Gradle Sync it will download the dependencies from Internet(All JAR Files). This solved it for me. No Editing in Gradle file ,all was done by Android Studio Automatically. Using Android Studio 2.2 :)

Also don't forget to install Java JDK 1.x(7 or 8 all works fine).

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

None if this worked for me. First of all I had to look at my provider to see how they activate SSL in .htaccess my provider gives

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteCond %{HTTP:HTTPS} !on
   RewriteRule (.*) https://%{SERVER_NAME}/$1 [QSA,L,R=301]
</IfModule>

But what took me days of research is I had to add to wp-config.php the following lines as my provided site is behind a proxy :

/**
 * Force le SSL
 */
define('FORCE_SSL_ADMIN', true);
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false) $_SERVER['HTTPS']='on';

API 23 provides the following method:

navigationView.setCheckedItem(R.id.nav_item_id);

However, for some reason this function did not cause the code behind the navigation item to run. The method certainly highlights the item in the navigation drawer, or 'checks' it, but it does not seem to call the OnNavigationItemSelectedListener resulting in a blank screen on start-up if your start-up screen depends on navigation drawer selections. It is possible to manually call the listener, but it seems hacky:

if (savedInstanceState == null) this.onNavigationItemSelected(navigationView.getMenu().getItem(0));

The above code assumes:

1. You have implemented NavigationView.OnNavigationItemSelectedListener in your activity
2. You have already called:
   navigationView.setNavigationItemSelectedListener(this);
3. The item you wish to select is located in position 0

The best solution is to change buildDir in build.gradle:

For example:

allprojects {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    repositories {
        jcenter()
    }
}

Rebuild and happy coding.

Add to your build.gradle:

test {
    useJUnitPlatform()
}

I was able to get build to work with Build Tools 23.0.0 rc1 if I also opened the project level build.gradle file and set the version of the android build plugin to 1.3.0-beta1. Also, I'm tracking the canary and preview builds and just updated a few seconds before, so perhaps that helped.

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0-beta1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

In my case, I got this error when there are 2 or more libraries conflict (same library but different versions). Check your app build.gradle in dependencies block.

In my case this error was caused by empty layout xml file.

I created the empty file but forgot to add any content to it. AndroidStudio gave this misleading error message, but when I executed the gradle build from command line I could see the real error like "Error parsing XML: no element found" and the file name.

Adding basic layout xml content fixed the error.

Check the latest version of Gradle Plugin Here:

You should change this in dependencies of app settings

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:[PLACE VERSION CODE HERE]'

}

}

Have you enabled multidexing?. Do extend your main Application class with MultiDexApplication. I have got additional exception mesage before the error. They are as follows.

Uncaught translation error: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: GC overhead limit exceeded

Uncaught translation error: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space
2 errors; aborting

This clearly tells that the error occurred due to out of memory. Try the following:

1. extend your main Application class with MultiDexApplication.
2. close unused applications from background and restart Android Studio.

This will do the trick ;)

I had faced this similar error too. In my case it was one of my picture files in my drawable folder. Removing the picture that was unused solved the problem for me. So, make sure to remove any unused items from drawable folder.

Try to put this line of code in your main projects gradle script:

configurations { all*.exclude group: 'com.android.support', module: 'support-v4' }

I have two libraries linked to my project and they where using 'com.android.support:support-v4:22.0.0'.

Hope it helps someone.

i had the same problem, i added the following lines in build.gradle

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

        maven {
            url 'http://dl.bintray.com/dev-fingerlinks/maven'
        }
        mavenCentral()

Try updating gradle dependency to 2.4. For that you need to go to File -> Project Structure -> Project -> Gradle version.

There you need to change from 2.2.1 to 2.4. Wait for new gradle version to be downloaded.

And you are ready to go.

By changing runProguard to minifyEnabled, part of the issue gets fixed.

But the fix can cause "Library Projects cannot set application Id" (you can find the fix for this here Android Studio 1.0 and error "Library projects cannot set applicationId").

By removing application Id in the build.gradle file, you should be good to go.

For me it worked after I did:

• Cleaning solution.
• Deleting the app from the phone I've debugged it at.
• Closing Visual Studio.
• Deleting folders /bin/ and /obj/ in android projects.
• Launching solution again.

The best way is using NotificationCenter to catch keyboard actions. You can follow the steps in this short article https://medium.com/@demirciy/keyboard-handling-deb1a96a8207

If you work on Windows , you must start Android Studio name by Administrator. It solved my problem

I fixed this problem. I just modified the compileSdk Version from android_L to 19 to target my nexus 4.4.4.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.2'
    }
}
apply plugin: 'com.android.application'

repositories {
    jcenter()
}

android {
    **compileSdkVersion 'android-L'** modified to 19
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.antwei.uiframework.ui"
        minSdkVersion 14
        targetSdkVersion 'L'
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    **compile 'com.android.support:support-v4:21.+'** modified to compile 'com.android.support:support-v4:20.0.0'
}

how to modified the value by ide.

select file->Project Structure -> Facets -> android-gradle and then modified the compile Sdk Version from android_L to 19

sorry I don't have enough reputation to add pictures

I used version 2.4.0 of socket.io in easyRTC and used the following code in server_ssl.js which worked for me

io = require("socket.io")(webServer, {
  handlePreflightRequest: (req, res) => {
    res.writeHead(200, {
      "Access-Control-Allow-Origin": req.headers.origin,
      "Access-Control-Allow-Methods": "GET,POST,OPTIONS",
      "Access-Control-Allow-Headers": "Origin, X-Requested-With, Content-Type, Accept, Referer, User-Agent, Host, Authorization",
      "Access-Control-Allow-Credentials": true,
      "Access-Control-Max-Age":86400
    });
    res.end();
  }
});

HERE ARE SIMPLE STEPS TO REMOVE PUBLIC IN URL (Laravel 5)

1: Copy all files form public folder and past them in laravel root folder

2: Open index.php and change

From

 require __DIR__.'/../bootstrap/autoload.php';

To

 require __DIR__.'/bootstrap/autoload.php';

And

$app = require_once __DIR__.'/../bootstrap/app.php';

To

$app = require_once __DIR__.'/bootstrap/app.php';

In laravel 4 path 2 is $app = require_once __DIR__.'/bootstrap/start.php'; instead of $app = require_once __DIR__.'/bootstrap/app.php';/app.php

That is it.

Your login root should be /usr/local/directadmin/conf/mysql.conf. Then try following

UPDATE mysql.user SET password=PASSWORD('$w0rdf1sh') WHERE user='tate256' AND Host='10.10.2.30';
FLUSH PRIVILEGES;

Host is your mysql host.

To diagnose this error quickly drop to a terminal or use the terminal built into Android Studio (accessible on in bottom status bar). Change to the main directory for your PROJECT (where settings.gradle is located).

1.) Check to make sure your settings.gradle includes the subproject. Something like this. This ensures your multi-project build knows about your library sub-project.

include ':apps:App1', ':apps:App2', ':library:Lib1'

Where the text between the colons are sub-directories.

2.) Run the following gradle command just see if Gradle can give you a list of tasks for the library. Use the same qualifier in the settings.gradle definition. This will uncover issues with the Library build script in isolation.

./gradlew :library:Lib1:tasks --info

3.) Make sure the output from the last step listed an "assembleDefault" task. If it didn't make sure the Library is including the Android Library plugin in build.gradle. Like this at the very top.

apply plugin: 'com.android.library'

I know the original poster's question was answered but I believe the answer has evolved over the past year and I think there are multiple reasons for the error. I think this resolution flow should assist those who run into the various issues.

Your module name must be camelCase eg. pdfLib. I had same issue because I my module name was 'PdfLib' and after renaming it to 'pdfLib'. It worked. The issue was not in my device but in jenkins server. So, check and see if you have such modulenames

You can try: right click on the project and then click clean. After this run the project.

It works for me.

Define versionName in AndroidManifest.xml

android:versionName="5.1.5"

Inside android{...} block in build.gradle of app level :

defaultConfig {
        applicationId "com.example.autoincrement"
        minSdkVersion 18
        targetSdkVersion 23
        multiDexEnabled true
        def version = getIncrementationVersionName()
        versionName version
}

Outside android{...} block in build.gradle of app level :

def getIncrementedVersionName() {
    List<String> runTasks = gradle.startParameter.getTaskNames();

    //find version name in manifest
    def manifestFile = file('src/main/AndroidManifest.xml')
    def matcher = Pattern.compile('versionName=\"(\\d+)\\.(\\d+)\\.(\\d+)\"').matcher(manifestFile.getText())
    matcher.find()

    //extract versionName parts
    def firstPart = Integer.parseInt(matcher.group(1))
    def secondPart = Integer.parseInt(matcher.group(2))
    def thirdPart = Integer.parseInt(matcher.group(3))

    //check is runTask release or not
    // if release - increment version
    for (String item : runTasks) {
        if (item.contains("assemble") && item.contains("Release")) {
            thirdPart++
            if (thirdPart == 10) {
                thirdPart = 0;
                secondPart++
                if (secondPart == 10) {
                    secondPart = 0;
                    firstPart++
                }
            }
        }
    }

    def versionName = firstPart + "." + secondPart + "." + thirdPart

    // update manifest
    def manifestContent = matcher.replaceAll('versionName=\"' + versionName + '\"')
    manifestFile.write(manifestContent)

    println "incrementVersionName = " + versionName

    return versionName
}

After create singed APK :

android:versionName="5.1.6"

Note : If your versionName different from my, you need change regex and extract parts logic.

Try this once and make sure you are not getting any error in project Structure saying that "ComGoogleAndroidGmsPlay not added"

Open File > Project Structure and check for below all. If error is shown click on Red bulb marked and click on "Add to dependency".

This is a bug in Android Studio and fixed for the next release(0.4.3)

Check Is Initial View Controller in the Attributes Inspector.

Important to know in what file it comes to this error (in you example it is META-INF/LICENSE.txt) , in my case it was in META-INF/LICENSE [without ".txt"], and then in the file META-INF/ASL2.0 so I added to my build.gradle this lines:

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/ASL2.0'
    }
}

Very important (!) -> add the name of the file in the same style, that you see it in the error message: the text is case sensitive, and there is a difference between *.txt and *(without "txt").

The most common reason could be the database connection string. You have to change the connection string attachDBFile=|DataDirectory|file_name.mdf. there might be problem in host name which would be (local),localhost or .\sqlexpress.

After compiling my code in Android Studio, I found it here:

~\MyApp_Name\app\build\outputs\apk\app-debug.apk

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

You do not include a <scope> tag in your dependency. If you add it, your dependency becomes something like:

<dependency>
     <groupId>org.openrdf.sesame</groupId>
     <artifactId>sesame-runtime</artifactId>
     <version>2.7.2</version>
     <scope> ... </scope>
</dependency>

The "scope" tag tells maven at which stage of the build your dependency is needed. Examples for the values to put inside are "test", "provided" or "runtime" (omit the quotes in your pom). I do not know your dependency so I cannot tell you what value to choose. Please consult the Maven documentation and the documentation of your dependency.

I was looking for caching for my phonegap app storage and I found the answer of @TecHunter which is great but done using localCache.

I found and come to know that localStorage is another alternative to cache the data returned by ajax call. So, I created one demo using localStorage which will help others who may want to use localStorage instead of localCache for caching.

Ajax Call:

$.ajax({
    type: "POST",
    dataType: 'json',
    contentType: "application/json; charset=utf-8",
    url: url,
    data: '{"Id":"' + Id + '"}',
    cache: true, //It must "true" if you want to cache else "false"
    //async: false,
    success: function (data) {
        var resData = JSON.parse(data);
        var Info = resData.Info;
        if (Info) {
            customerName = Info.FirstName;
        }
    },
    error: function (xhr, textStatus, error) {
        alert("Error Happened!");
    }
});

To store data into localStorage:

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
    var success = originalOptions.success || $.noop,
        url = originalOptions.url;

    options.cache = false; //remove jQuery cache as we have our own localStorage
    options.beforeSend = function () {
        if (localStorage.getItem(url)) {
            success(localStorage.getItem(url));
            return false;
        }
        return true;
    };
    options.success = function (data, textStatus) {
        var responseData = JSON.stringify(data.responseJSON);
        localStorage.setItem(url, responseData);
        if ($.isFunction(success)) success(responseJSON); //call back to original ajax call
    };
}
});

If you want to remove localStorage, use following statement wherever you want:

localStorage.removeItem("Info");

Hope it helps others!

Here's a gitHub project that does just that.

It records audio from the browser in mp3 format, and it automatically saves it to the webserver. https://github.com/Audior/Recordmp3js

You can also view a detailed explanation of the implementation: http://audior.ec/blog/recording-mp3-using-only-html5-and-javascript-recordmp3-js/

Here's how to do this with lxml without having to hard-code the namespaces or scan the text for them (as Martijn Pieters mentions):

from lxml import etree
tree = etree.parse("filename")
root = tree.getroot()
root.findall('owl:Class', root.nsmap)

UPDATE:

5 years later I'm still running into variations of this issue. lxml helps as I showed above, but not in every case. The commenters may have a valid point regarding this technique when it comes merging documents, but I think most people are having difficulty simply searching documents.

Here's another case and how I handled it:

<?xml version="1.0" ?><Tag1 xmlns="http://www.mynamespace.com/prefix">
<Tag2>content</Tag2></Tag1>

xmlns without a prefix means that unprefixed tags get this default namespace. This means when you search for Tag2, you need to include the namespace to find it. However, lxml creates an nsmap entry with None as the key, and I couldn't find a way to search for it. So, I created a new namespace dictionary like this

namespaces = {}
# response uses a default namespace, and tags don't mention it
# create a new ns map using an identifier of our choice
for k,v in root.nsmap.iteritems():
    if not k:
        namespaces['myprefix'] = v
e = root.find('myprefix:Tag2', namespaces)

the line below shows you haven't set an DataAttribute like required on AgreementNumber

<input id="AgreementNumber" name="AgreementNumber" size="30" type="text" value="387893" />

you need

[Required]
public String AgreementNumber{get;set;}

i have changed my old path: jdbc:odbc:thin:@localhost:1521:orcl

to new : jdbc:oracle:thin:@//localhost:1521/orcl

and it worked for me.....hurrah!! image

If you check the length seperately, you can do the following:

var regularExpression  = /^[a-zA-Z]$/;

if (regularExpression.test(newPassword)) {
    alert("password should contain atleast one number and one special character");
    return false;
} 

Another way to accomplish this is a combination of Justus Thane's and mklement0's answers. It doesn't make sense to do it this way when you look at a one liner example, but when you're trying to mass-edit a file or a bunch of filenames it comes in pretty handy:

$test = '   One      for the money   '
$option = [System.StringSplitOptions]::RemoveEmptyEntries
$($test.split(' ',$option)).foreach{$_}

This will come out as:

One
for
the
money

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

Have you tried upping the maxconnection attribute of your processModel setting?

I've been playing with this code for a while now and I have something that works well for me. Log files are numbered with leading '0' but retain their file extension. And I know everyone likes to make functions for everything but I started to remove functions that performed 1 simple task. Why use many word when few do trick? Will likely remove other functions and perhaps create functions out of other blocks. I keep the logger script in a central share and make a local copy if it has changed, or load it from the central location if needed.

First I import the logger:

#Change directory to the script root
cd $PSScriptRoot

#Make a local copy if changed then Import logger
if(test-path "D:\Scripts\logger.ps1"){
    if (Test-Path "\\<server>\share\DCS\Scripts\logger.ps1") {
        if((Get-FileHash "\\<server>\share\DCS\Scripts\logger.ps1").Hash -ne (Get-FileHash "D:\Scripts\logger.ps1").Hash){
            rename-Item -path "..\logger.ps1" -newname "logger$(Get-Date -format 'yyyyMMdd-HH.mm.ss').ps1" -force
            Copy-Item "\\<server>\share\DCS\Scripts\logger.ps1" -destination "..\" -Force 
        }
    }
}else{
    Copy-Item "\\<server>\share\DCS\Scripts\logger.ps1" -destination "..\" -Force
}
. "..\logger.ps1"

Define the log file:

$logfile = (get-location).path + "\Log\" + $QProfile.replace(" ","_") + "-$metricEnv-$ScriptName.log"

What I log depends on debug levels that I created:

if ($Debug -ge 1){
    $message = "<$pid>Debug:$Debug`-Adding tag `"MetricClass:temp`" to $host_name`:$metric_name"
    Write-Log $message $logfile "DEBUG"
}

I would probably consider myself a bit of a "hack" when it comes to coding so this might not be the prettiest but here is my version of logger.ps1:

Your example does work. Here's a simplified version.

package main

import "fmt"

func weird(i int) interface{} {
    if i < 0 {
        return "negative"
    }
    return i
}

func main() {
    var i = 42
    if w, ok := weird(7).(int); ok {
        i += w
    }
    if w, ok := weird(-100).(int); ok {
        i += w
    }
    fmt.Println("i =", i)
}

Output:
i = 49

It uses Type assertions.

While that particular idiom is common, even more common is for people to use = when they mean ==. The convention when you really mean the = is to use an extra layer of parentheses:

while ((list = list->next)) { // yes, it's an assignment

You have mixed 2 standard.

The error is in $header = "Content-Type: multipart/form-data; boundary='123456f'";

The function http_build_query($filedata) is only for "Content-Type: application/x-www-form-urlencoded", or none.

a simple way to do that

we can call all model first

@using project.Models

then send your model with viewbag

// for list
ViewBag.Name = db.YourModel.ToList();

// for one
ViewBag.Name = db.YourModel.Find(id);

and in view

// for list
List<YourModel> Name = (List<YourModel>)ViewBag.Name ;

//for one
YourModel Name = (YourModel)ViewBag.Name ;

then easily use this like Model

Don't use os.system. It has been deprecated in favor of subprocess. From the docs: "This module intends to replace several older modules and functions: os.system, os.spawn".

Like in your case:

bashCommand = "cwm --rdf test.rdf --ntriples > test.nt"
import subprocess
process = subprocess.Popen(bashCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()

Edit 2

I finally found a solution by implementing my forward action like that:

private void applyForward() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    // Find where to redirect the user.
    String redirect = getTheFromOutCome();

    // Change the Navigation context.
    NavigationHandler myNav = facesContext.getApplication().getNavigationHandler();
    myNav.handleNavigation(facesContext, null, redirect);

    // Update the view root
    UIViewRoot vr = facesContext.getViewRoot();
    if (vr != null) {
        // Get the URL where to redirect the user
        String url = facesContext.getExternalContext().getRequestContextPath();
        url = url + "/" + vr.getViewId().replace(".xhtml", ".jsf");
        Object obj = facesContext.getExternalContext().getResponse();
        if (obj instanceof HttpServletResponse) {
            HttpServletResponse response = (HttpServletResponse) obj;
            try {
                // Redirect the user now.
                response.sendRedirect(response.encodeURL(url));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

It works (at least regarding my first tests), but I still don't like the way it is implemented... Any better idea?

Edit This solution does not work. Indeed, when the doForward() function is called, the JSF lifecycle has already been started, and then recreate a new request is not possible.

One idea to solve this issue, but I don't really like it, is to force the doForward() action during one of the setBindedInputHidden() method:

private boolean actionDefined = false;
private boolean actionParamDefined = false;

public void setHiddenActionParam(HtmlInputHidden hiddenActionParam) {
    this.hiddenActionParam = hiddenActionParam;
    String actionParam = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("actionParam");
    this.hiddenActionParam.setValue(actionParam);
    actionParamDefined = true;
    forwardAction();
}

public void setHiddenAction(HtmlInputHidden hiddenAction) {
    this.hiddenAction = hiddenAction;
    String action = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("action");
    this.hiddenAction.setValue(action);
    actionDefined = true;
    forwardAction();
}

private void forwardAction() {
    if (!actionDefined || !actionParamDefined) {
        // As one of the inputHidden was not binded yet, we do nothing...
        return;
    }
    // Now, both action and actionParam inputHidden are binded, we can execute the forward...
    doForward(null);
}

This solution does not involve any Javascript call, and works does not work.

    public static string StringSha256Hash(string text) =>
        string.IsNullOrEmpty(text) ? string.Empty : BitConverter.ToString(new System.Security.Cryptography.SHA256Managed().ComputeHash(System.Text.Encoding.UTF8.GetBytes(text))).Replace("-", string.Empty);

NSArray *_returnedArguments = [serverOutput componentsSeparatedByString:@":"];

_returnedArguments is an array of NSStrings which the UITextField text property is expecting. No need to convert.

Syntax error:

[_appDelegate loggedIn:usernameField.text:passwordField.text:(int)[[_returnedArguments objectAtIndex:2] intValue]];

If your _appDelegate has a passwordField property, then you can set the text using the following

[[_appDelegate passwordField] setText:[_returnedArguments objectAtIndex:2]];

base64 encode/decode example:

import base64

mystr = 'O João mordeu o cão!'

# Encode
mystr_encoded = base64.b64encode(mystr.encode('utf-8'))
# b'TyBKb8OjbyBtb3JkZXUgbyBjw6NvIQ=='

# Decode
mystr_encoded = base64.b64decode(mystr_encoded).decode('utf-8')
# 'O João mordeu o cão!'

I've been reading that hashing functions like SHA256 weren't really intended for use with storing passwords: https://patrickmn.com/security/storing-passwords-securely/#notpasswordhashes

Instead adaptive key derivation functions like PBKDF2, bcrypt or scrypt were. Here is a PBKDF2 based one that Microsoft wrote for PasswordHasher in their Microsoft.AspNet.Identity library:

/* =======================
 * HASHED PASSWORD FORMATS
 * =======================
 * 
 * Version 3:
 * PBKDF2 with HMAC-SHA256, 128-bit salt, 256-bit subkey, 10000 iterations.
 * Format: { 0x01, prf (UInt32), iter count (UInt32), salt length (UInt32), salt, subkey }
 * (All UInt32s are stored big-endian.)
 */

public string HashPassword(string password)
{
    var prf = KeyDerivationPrf.HMACSHA256;
    var rng = RandomNumberGenerator.Create();
    const int iterCount = 10000;
    const int saltSize = 128 / 8;
    const int numBytesRequested = 256 / 8;

    // Produce a version 3 (see comment above) text hash.
    var salt = new byte[saltSize];
    rng.GetBytes(salt);
    var subkey = KeyDerivation.Pbkdf2(password, salt, prf, iterCount, numBytesRequested);

    var outputBytes = new byte[13 + salt.Length + subkey.Length];
    outputBytes[0] = 0x01; // format marker
    WriteNetworkByteOrder(outputBytes, 1, (uint)prf);
    WriteNetworkByteOrder(outputBytes, 5, iterCount);
    WriteNetworkByteOrder(outputBytes, 9, saltSize);
    Buffer.BlockCopy(salt, 0, outputBytes, 13, salt.Length);
    Buffer.BlockCopy(subkey, 0, outputBytes, 13 + saltSize, subkey.Length);
    return Convert.ToBase64String(outputBytes);
}

public bool VerifyHashedPassword(string hashedPassword, string providedPassword)
{
    var decodedHashedPassword = Convert.FromBase64String(hashedPassword);

    // Wrong version
    if (decodedHashedPassword[0] != 0x01)
        return false;

    // Read header information
    var prf = (KeyDerivationPrf)ReadNetworkByteOrder(decodedHashedPassword, 1);
    var iterCount = (int)ReadNetworkByteOrder(decodedHashedPassword, 5);
    var saltLength = (int)ReadNetworkByteOrder(decodedHashedPassword, 9);

    // Read the salt: must be >= 128 bits
    if (saltLength < 128 / 8)
    {
        return false;
    }
    var salt = new byte[saltLength];
    Buffer.BlockCopy(decodedHashedPassword, 13, salt, 0, salt.Length);

    // Read the subkey (the rest of the payload): must be >= 128 bits
    var subkeyLength = decodedHashedPassword.Length - 13 - salt.Length;
    if (subkeyLength < 128 / 8)
    {
        return false;
    }
    var expectedSubkey = new byte[subkeyLength];
    Buffer.BlockCopy(decodedHashedPassword, 13 + salt.Length, expectedSubkey, 0, expectedSubkey.Length);

    // Hash the incoming password and verify it
    var actualSubkey = KeyDerivation.Pbkdf2(providedPassword, salt, prf, iterCount, subkeyLength);
    return actualSubkey.SequenceEqual(expectedSubkey);
}

Note this requires Microsoft.AspNetCore.Cryptography.KeyDerivation nuget package installed which requires .NET Standard 2.0 (.NET 4.6.1 or higher). For earlier versions of .NET see the Crypto class from Microsoft's System.Web.Helpers library.

Update Nov 2015
Updated answer to use an implementation from a different Microsoft library which uses PBKDF2-HMAC-SHA256 hashing instead of PBKDF2-HMAC-SHA1 (note PBKDF2-HMAC-SHA1 is still secure if iterCount is high enough). You can check out the source the simplified code was copied from as it actually handles validating and upgrading hashes implemented from previous answer, useful if you need to increase iterCount in the future.

Since Java 8 you can use lambdas and achieve shorter code:

File dir = new File(xmlFilesDirectory);
File[] files = dir.listFiles((d, name) -> name.endsWith(".xml"));

There are graph databases like:

• Neo4j
• Sesame
• AllegroGraph
• different RDF/triplestores

A graph database stores data as nodes and relationships/edges.This is a good fit for semi-structured data, interconnected information and domains with deep relationships/traversal, for example social networks and knowledge representation. The data model is highly flexible and "whiteboard friendly". The underlying data model of the semantic web, RDF, is also a (labeled, directed multi-)graph.

Other stackoverflow threads with information on graph databases:

• The Next-gen Databases
• Non-Relational Database Design (listing some +/-)
• Have anyone used Graph based databases

The wildcard library efficiently does both glob and regex filename matching:

http://code.google.com/p/wildcard/

The implementation is succinct -- JAR is only 12.9 kilobytes.

python supports arbitrarily large integers naturally:

example:

>>> 10**1000
10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

You could even get, for example of a huge integer value, fib(4000000).

But still it does not (for now) supports an arbitrarily large float !!

If you need one big, large, float then check up on the decimal Module. There are examples of use on these foruns: OverflowError: (34, 'Result too large')

Another reference: http://docs.python.org/2/library/decimal.html

You can even using the gmpy module if you need a speed-up (which is likely to be of your interest): Handling big numbers in code

Another reference: https://code.google.com/p/gmpy/

In practical terms, the limit is usually determined by stack space. If each thread gets a 1MB stack (I can't remember if that is the default on Linux), then you a 32-bit system will run out of address space after 3000 threads (assuming that the last gb is reserved to the kernel).

However, you'll most likely experience terrible performance if you use more than a few dozen threads. Sooner or later, you get too much context-switching overhead, too much overhead in the scheduler, and so on. (Creating a large number of threads does little more than eat a lot of memory. But a lot of threads with actual work to do is going to slow you down as they're fighting for the available CPU time)

What are you doing where this limit is even relevant?

I had the same problem, but this worked for me:

<a ng-href="javascript:void(0);#tagId"></a>

The external file is the best and typical bulk-data

The term "bulk data" is related to "a lot of data", so it is natural to use original raw data, with no need to transform it into SQL. Typical raw data files for "bulk insert" are CSV and JSON formats.

Bulk insert with some transformation

In ETL applications and ingestion processes, we need to change the data before inserting it. Temporary table consumes (a lot of) disk space, and it is not the faster way to do it. The PostgreSQL foreign-data wrapper (FDW) is the best choice.

CSV example. Suppose the tablename (x, y, z) on SQL and a CSV file like

fieldname1,fieldname2,fieldname3
etc,etc,etc
... million lines ...

You can use the classic SQL COPY to load (as is original data) into tmp_tablename, them insert filtered data into tablename... But, to avoid disk consumption, the best is to ingested directly by

INSERT INTO tablename (x, y, z)
  SELECT f1(fieldname1), f2(fieldname2), f3(fieldname3) -- the transforms 
  FROM tmp_tablename_fdw
  -- WHERE condictions
;

You need to prepare database for FDW, and instead static tmp_tablename_fdw you can use a function that generates it:

CREATE EXTENSION file_fdw;
CREATE SERVER import FOREIGN DATA WRAPPER file_fdw;
CREATE FOREIGN TABLE tmp_tablename_fdw(
  ...
) SERVER import OPTIONS ( filename '/tmp/pg_io/file.csv', format 'csv');

JSON example. A set of two files, myRawData1.json and Ranger_Policies2.json can be ingested by:

INSERT INTO tablename (fname, metadata, content)
 SELECT fname, meta, j  -- do any data transformation here
 FROM jsonb_read_files('myRawData%.json')
 -- WHERE any_condiction_here
;

where the function jsonb_read_files() reads all files of a folder, defined by a mask:

CREATE or replace FUNCTION jsonb_read_files(
  p_flike text, p_fpath text DEFAULT '/tmp/pg_io/'
) RETURNS TABLE (fid int,  fname text, fmeta jsonb, j jsonb) AS $f$
  WITH t AS (
     SELECT (row_number() OVER ())::int id, 
           f as fname,
           p_fpath ||'/'|| f as f
     FROM pg_ls_dir(p_fpath) t(f)
     WHERE    f like p_flike
  ) SELECT id,  fname,
         to_jsonb( pg_stat_file(f) ) || jsonb_build_object('fpath',p_fpath),
         pg_read_file(f)::jsonb
    FROM t
$f$  LANGUAGE SQL IMMUTABLE;

Lack of gzip streaming

The most frequent method for "file ingestion" (mainlly in Big Data) is preserving original file on gzip format and transfering it with streaming algorithm, anything that can runs fast and without disc consumption in unix pipes:

 gunzip remote_or_local_file.csv.gz | convert_to_sql | psql 

So ideal (future) is a server option for format .csv.gz.

Update: created a js fiddle here to see it live: http://jsfiddle.net/HFMvX/

I went through tons of google searches and didn't find anything satisfying. i like how passpack have done it so essentially reverse-engineered their approach, here we go:

function scorePassword(pass) {
    var score = 0;
    if (!pass)
        return score;

    // award every unique letter until 5 repetitions
    var letters = new Object();
    for (var i=0; i<pass.length; i++) {
        letters[pass[i]] = (letters[pass[i]] || 0) + 1;
        score += 5.0 / letters[pass[i]];
    }

    // bonus points for mixing it up
    var variations = {
        digits: /\d/.test(pass),
        lower: /[a-z]/.test(pass),
        upper: /[A-Z]/.test(pass),
        nonWords: /\W/.test(pass),
    }

    var variationCount = 0;
    for (var check in variations) {
        variationCount += (variations[check] == true) ? 1 : 0;
    }
    score += (variationCount - 1) * 10;

    return parseInt(score);
}

Good passwords start to score around 60 or so, here's function to translate that in words:

function checkPassStrength(pass) {
    var score = scorePassword(pass);
    if (score > 80)
        return "strong";
    if (score > 60)
        return "good";
    if (score >= 30)
        return "weak";

    return "";
}

you might want to tune this a bit but i found it working for me nicely

if you overide the onKey method for the fragment view you're gonna need :

    view.setFocusableInTouchMode(true);
    view.requestFocus();
    view.setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                Log.i(tag, "keyCode: " + keyCode);
                if( keyCode == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) {
                    Log.i(tag, "onKey Back listener is working!!!");
                    getFragmentManager().popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
                    return true;
                } 
                return false;
            }
        });

Mine where all variable lengths and a set max width would not work for me so setting my css to 100% worked like a charm.

.tooltip-inner {
    max-width: 100%;
}

If someone wants to try a slightly different approach, they can use FLEX.

HTML

<div class="test">
    <div>Div 1</div>
    <div>Div 2</div>
    <div>Div 3</div>
    <div>Div 4</div>
</div>

CSS

.test {
    display: flex;
    flex-flow: row wrap;
    justify-content: space-around;
}
.test > div {
    margin-top: 10px;
    padding: 20px;
    background-color: #FF0000;
}

Here is the fiddle: http://jsfiddle.net/ynemh3c2/ (Try adding/removing divs as well)

Here is where I learned about this: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

Use a slice, not an arrray. Just create it using

reg := []string {"a","b","c"}

An alternative would have been to convert your array to a slice when joining :

fmt.Println(strings.Join(reg[:],","))

Read the Go blog about the differences between slices and arrays.

Store it in a cookie that only lasts for the current browsing session

I had this because something bad was in my vendor/bundle. Nothing to do with Apache, just in local dev env.

To fix, I deleted vendor\bundle, and also deleted the reference to it in my .bundle/config so it wouldn't get re-used.

Then, I re-bundled (which then installed to GEM_HOME instead of vendor/bundle and the problem went away.

In addition to Delan Azabani's answer, I like to share my console.js, and I use for the same purpose. I create a noop console using an array of function names, what is in my opinion a very convenient way to do this, and I took care of Internet Explorer, which has a console.log function, but no console.debug:

// Create a noop console object if the browser doesn't provide one...
if (!window.console){
  window.console = {};
}

// Internet Explorer has a console that has a 'log' function, but no 'debug'. To make console.debug work in Internet Explorer,
// We just map the function (extend for info, etc. if needed)
else {
  if (!window.console.debug && typeof window.console.log !== 'undefined') {
    window.console.debug = window.console.log;
  }
}

// ... and create all functions we expect the console to have (taken from Firebug).
var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
    "group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];

for (var i = 0; i < names.length; ++i){
  if(!window.console[names[i]]){
    window.console[names[i]] = function() {};
  }
}

you can use :target

or to filter by class name, use .classname:target

or filter by id name using #idname:target

#id01:target {      
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;

just wanted to add a pure javascript solution ( no JQuery )

function capitalize(str) {_x000D_
  strVal = '';_x000D_
  str = str.split(' ');_x000D_
  for (var chr = 0; chr < str.length; chr++) {_x000D_
    strVal += str[chr].substring(0, 1).toUpperCase() + str[chr].substring(1, str[chr].length) + ' '_x000D_
  }_x000D_
  return strVal_x000D_
}_x000D_
_x000D_
console.log(capitalize('hello world'));

When I did just a remove the option remained in the ddl on the view, but was gone in the html (if u inspect the page)

$("#ddlSelectList option[value='2']").remove(); //removes the option with value = 2
$('#ddlSelectList').val('').trigger('chosen:updated'); //refreshes the drop down list

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

I have a sample app where I prepare the intent and just pass the CITY_NAME in the intent to the maps marker activity which eventually calculates longitude and latitude by Geocoder using CITY_NAME.

Below is the code snippet of starting the maps marker activity and the complete MapsMarkerActivity.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    } else if (id == R.id.action_refresh) {
        Log.d(APP_TAG, "onOptionsItemSelected Refresh selected");
        new MainActivityFragment.FetchWeatherTask().execute(CITY, FORECAS_DAYS);
        return true;
    } else if (id == R.id.action_map) {
        Log.d(APP_TAG, "onOptionsItemSelected Map selected");
        Intent intent = new Intent(this, MapsMarkerActivity.class);
        intent.putExtra("CITY_NAME", CITY);
        startActivity(intent);
        return true;
    }

    return super.onOptionsItemSelected(item);
}

What solved my problem was to

1) Install the jdk under directory with no spaces:

C:/Java

Instead of

C:/Program Files/Java

This is a known issue in Windows. I fixed JAVA_HOME as well

2) I java 7 and java 8 on my laptop. So I defined the jvm using eclipse.ini. This is not a mandatory step if you don't have -vm entry in your eclipse.ini. I updated:

C:/Java/jdk1.7.0_79/jre/bin/javaw.exe

Instead of:

C:/Java/jdk1.7.0_79/bin/javaw.exe

Good luck

• A worker process runs as an executables file named W3wp.exe

• A Worker Process is user mode code whose role is to process requests, such as processing requests to return a static page.

• The worker process is controlled by the www service.

• worker processes also run application code, Such as ASP .NET applications and XML web Services.

• When Application pool receive the request, it simply pass the request to worker process (w3wp.exe) . The worker process“w3wp.exe” looks up the URL of the request in order to load the correct ISAPI extension. ISAPI extensions are the IIS way to handle requests for different resources. Once ASP.NET is installed, it installs its own ISAPI extension (aspnet_isapi.dll)and adds the mapping into IIS.

• When Worker process loads the aspnet_isapi.dll, it start an HTTPRuntime, which is the entry point of an application. HTTPRuntime is a class which calls the ProcessRequest method to start Processing.

For more detail refer URL http://aspnetnova.blogspot.in/2011/12/how-iis-process-for-aspnet-requests.html

In addition to toscho's answer I've noticed some webkit inconsistencies between Chrome 9-10 and Safari 5 with the CSS properties supported that are worth noting.

Specifically Chrome 9 and 10 do not support background-color, border, text-decoration and text-transform when styling the placeholder.

The full cross-browser comparison is here.

Microsoft have a proprietary CSS method of including embedded fonts (http://msdn.microsoft.com/en-us/library/ms533034(VS.85).aspx), but this probably shouldn't be recommended.

I've used sIFR before as this works great - it uses Javascript and Flash to dynamically replace normal text with some Flash containing the same text in the font you want (the font is embedded in a Flash file). This does not affect the markup around the text (it works by using a CSS class), you can still select the text, and if the user doesn't have Flash or has it disabled, it will degrade gracefully to the text in whatever font you specify in CSS (e.g. Arial).

You can also use CURRENT_TIMESTAMP, if you feel like being more ANSI compliant (though if you're porting code between database vendors, that'll be the least of your worries). It's exactly the same as GetDate() under the covers (see this question for more on that).

There's no ANSI equivalent for GetUTCDate(), however, which is probably the one you should be using if your app operates in more than a single time zone ...

compareTo() is called on one object, to compare it to another object. compare() is called on some object to compare two other objects.

The difference is where the logic that does actual comparison is defined.

Quick Answer

You should use the equals method since this is implemented to perform the comparison you want. toString() itself uses an iterator just like equals but it is a more inefficient approach. Additionally, as @Teepeemm pointed out, toString is affected by order of elements (basically iterator return order) hence is not guaranteed to provide the same output for 2 different maps (especially if we compare two different maps).

Note/Warning: Your question and my answer assume that classes implementing the map interface respect expected toString and equals behavior. The default java classes do so, but a custom map class needs to be examined to verify expected behavior.

See: http://docs.oracle.com/javase/7/docs/api/java/util/Map.html

boolean equals(Object o)

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.

Implementation in Java Source (java.util.AbstractMap)

Additionally, java itself takes care of iterating through all elements and making the comparison so you don't have to. Have a look at the implementation of AbstractMap which is used by classes such as HashMap:

 // Comparison and hashing

    /**
     * Compares the specified object with this map for equality.  Returns
     * <tt>true</tt> if the given object is also a map and the two maps
     * represent the same mappings.  More formally, two maps <tt>m1</tt> and
     * <tt>m2</tt> represent the same mappings if
     * <tt>m1.entrySet().equals(m2.entrySet())</tt>.  This ensures that the
     * <tt>equals</tt> method works properly across different implementations
     * of the <tt>Map</tt> interface.
     *
     * <p>This implementation first checks if the specified object is this map;
     * if so it returns <tt>true</tt>.  Then, it checks if the specified
     * object is a map whose size is identical to the size of this map; if
     * not, it returns <tt>false</tt>.  If so, it iterates over this map's
     * <tt>entrySet</tt> collection, and checks that the specified map
     * contains each mapping that this map contains.  If the specified map
     * fails to contain such a mapping, <tt>false</tt> is returned.  If the
     * iteration completes, <tt>true</tt> is returned.
     *
     * @param o object to be compared for equality with this map
     * @return <tt>true</tt> if the specified object is equal to this map
     */
    public boolean equals(Object o) {
        if (o == this)
            return true;

        if (!(o instanceof Map))
            return false;
        Map<K,V> m = (Map<K,V>) o;
        if (m.size() != size())
            return false;

        try {
            Iterator<Entry<K,V>> i = entrySet().iterator();
            while (i.hasNext()) {
                Entry<K,V> e = i.next();
                K key = e.getKey();
                V value = e.getValue();
                if (value == null) {
                    if (!(m.get(key)==null && m.containsKey(key)))
                        return false;
                } else {
                    if (!value.equals(m.get(key)))
                        return false;
                }
            }
        } catch (ClassCastException unused) {
            return false;
        } catch (NullPointerException unused) {
            return false;
        }

        return true;
    }

Comparing two different types of Maps

toString fails miserably when comparing a TreeMap and HashMap though equals does compare contents correctly.

Code:

public static void main(String args[]) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("2", "whatever2");
map.put("1", "whatever1");
TreeMap<String, Object> map2 = new TreeMap<String, Object>();
map2.put("2", "whatever2");
map2.put("1", "whatever1");

System.out.println("Are maps equal (using equals):" + map.equals(map2));
System.out.println("Are maps equal (using toString().equals()):"
        + map.toString().equals(map2.toString()));

System.out.println("Map1:"+map.toString());
System.out.println("Map2:"+map2.toString());
}

Output:

Are maps equal (using equals):true
Are maps equal (using toString().equals()):false
Map1:{2=whatever2, 1=whatever1}
Map2:{1=whatever1, 2=whatever2}

Wrap your two+ function calls in another function/method. Here are a couple variants of that idea:

1) Separate method

var Test = React.createClass({
   onClick: function(event){
      func1();
      func2();
   },
   render: function(){
      return (
         <a href="#" onClick={this.onClick}>Test Link</a>
      );
   }
});

or with ES6 classes:

class Test extends React.Component {
   onClick(event) {
      func1();
      func2();
   }
   render() {
      return (
         <a href="#" onClick={this.onClick}>Test Link</a>
      );
   }
}

2) Inline

<a href="#" onClick={function(event){ func1(); func2()}}>Test Link</a>

or ES6 equivalent:

<a href="#" onClick={() => { func1(); func2();}}>Test Link</a>

In case you have key value pairs in your input array, I used:

.filter(
          this.multi_items[0] != null && store.state.isSearchBox === false
            ? item =>
                _.map(this.multi_items, "value").includes(item["wijknaam"])
            : item => item["wijknaam"].includes("")
        );

where the input array is multi_items as: [{"text": "bla1", "value": "green"}, {"text": etc. etc.}]

_.map is a lodash function.

HTML
<img id="close" className="fa fa-close" src="" alt="" title="Close Me" />

CSS
#close[title]:hover:after {
  color: red;
  content: attr(title);
  position: absolute;
  left: 50px;
}

I think you're looking for;

  string[] skus = myLines.Select(x => x.Sku).ToArray();

However, if you're going to iterate over the sku's in subsequent code I recommend not using the ToArray() bit as it forces the queries execution prematurely and makes the applications performance worse. Instead you can just do;

  var skus = myLines.Select(x => x.Sku); // produce IEnumerable<string>

  foreach (string sku in skus) // forces execution of the query

In my experience over the past few months, I've realized that the best way to achieve this is:

class App extends React.Component{
  constructor(){
   super();
   this.state = {
    serverResponse: ''
   }
  }
  componentDidMount(){
     this.getData();
  }
  async getData(){
   const res = await axios.get('url-to-get-the-data');
   const { data } = await res;
   this.setState({serverResponse: data})
 }
 render(){
  return(
     <div>
       {this.state.serverResponse}
     </div>
  );
 }
}

If you are trying to make post request on events such as click, then call getData() function on the event and replace the content of it like so:

async getData(username, password){
 const res = await axios.post('url-to-post-the-data', {
   username,
   password
 });
 ...
}

Furthermore, if you are making any request when the component is about to load then simply replace async getData() with async componentDidMount() and change the render function like so:

render(){
 return (
  <div>{this.state.serverResponse}</div>
 )
}

If you need to do it manually, one time:

First, merge in a temporary table, with something like:

create table MERGED as select * from table 1 UNION select * from table 2

Then, identify the primary key constraints with something like

SELECT COUNT(*), PK from MERGED GROUP BY PK HAVING COUNT(*) > 1

Where PK is the primary key field...

Solve the duplicates.

Rename the table.

[edited - removed brackets in the UNION query, which was causing the error in the comment below]

In case of multi monitor and If you prefer to center on correct monitor/screen then you might like to try these lines:

// Save values for future(for example, to center a form on next launch)
int screen_x = Screen.FromControl(Form).WorkingArea.X;
int screen_y = Screen.FromControl(Form).WorkingArea.Y;

// Move it and center using correct screen/monitor
Form.Left = screen_x;
Form.Top = screen_y;
Form.Left += (Screen.FromControl(Form).WorkingArea.Width - Form.Width) / 2;
Form.Top += (Screen.FromControl(Form).WorkingArea.Height - Form.Height) / 2;

As of API 24, sending a file:// URI to another app will throw a FileUriExposedException. Instead, use FileProvider to send a content:// URI:

public File getFile(Context context, String fileName) {
    if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        return null;
    }

    File storageDir = context.getExternalFilesDir(null);
    return new File(storageDir, fileName);
}

public Uri getFileUri(Context context, String fileName) {
    File file = getFile(context, fileName);
    return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
}

You must also define the FileProvider in your manifest:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Example file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-files-path name="name" path="path" />
</paths>

Replace "name" and "path" as appropriate.

To give the PDF viewer access to the file, you also have to add the FLAG_GRANT_READ_URI_PERMISSION flag to the intent:

private void displayPdf(String fileName) {
    Uri uri = getFileUri(this, fileName);

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(uri, "application/pdf");

    // FLAG_GRANT_READ_URI_PERMISSION is needed on API 24+ so the activity opening the file can read it
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_GRANT_READ_URI_PERMISSION);

    if (intent.resolveActivity(getPackageManager()) == null) {
        // Show an error
    } else {
        startActivity(intent);
    }
}

See the FileProvider documentation for more details.

Normally, mutt sets the From: header based on the from configuration variable you set in ~/.muttrc:

set from="Fubar <foo@bar>"

If this is not set, mutt uses the EMAIL environment variable by default. In which case, you can get away with calling mutt like this on the command line (as opposed to how you showed it in your comment):

EMAIL="foo@bar" mutt -s '$MailSubject' -c "abc@def"

However, if you want to be able to edit the From: header while composing, you need to configure mutt to allow you to edit headers first. This involves adding the following line in your ~/.muttrc:

set edit_headers=yes

After that, next time you open up mutt and are composing an E-mail, your chosen text editor will pop up containing the headers as well, so you can edit them. This includes the From: header.

Another option is to take advantage of version-specific drawable (mipmap) directories to supply different graphics for Lollipop and above.

In my app, the "v21" directories contain icons with transparent text while the other directories contain non-transparent version (for versions of Android older than Lollipop).

Which should look something like this:

This way, you don't need to check for version numbers in code, e.g.

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.mipmap.ic_notification)
        .setContentTitle(title)
        .setContentText(message)
        .setAutoCancel(true)
        .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

Likewise, you can reference "ic_notification" (or whatever you choose to call it) in your GCM payload if you use the "icon" attribute.

The post is old but I found a perfect CSS for the purpose and I want to share it.

A sticky element toggles between relative and fixed, depending on the scroll position. It is positioned relative until a given offset position is met in the viewport - then it "sticks" in place (like position:fixed).

    div.sticky {
        position: -webkit-sticky; /* Safari */
        position: sticky;
        top: 0;
        background-color: green;
        border: 2px solid #4CAF50;
    }

Change your config.php:

$config['sess_use_database'] = TRUE;

To:

$config['sess_use_database'] = FALSE;

It works for me.

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

Just use GetDate() not Select GetDate()

DECLARE @LastChangeDate as date 
SET @LastChangeDate = GETDATE() 

but if it's SQL Server, you can also initialize in same step as declaration...

DECLARE @LastChangeDate date = getDate()

As an alternative, you could use the jQuery UI Position utility e.g.

$(".mytext").mouseover(function() {
    var target = $(this);
    $("#dialog").dialog("widget").position({
       my: 'left',
       at: 'right',
       of: target
    });
}

Originally ZIP files were created with MS-DOS command line software from PKWare, the two programs were PKZIP.EXE and PKUNZIP.EXE. I think you can still download PKUNZIP at the PKWare site here:

http://www.pkware.com/software-pkzip/dos-compression

The actual command line could look something like this:

C:\>pkunzip c:\myzipfile.zip c:\extracttothisfolder\

look at this : http://docs.oracle.com/javase/6/docs/api/java/util/Properties.html#load(java.io.Reader)

the properties accept an Reader object as arguments, which you can create from an InputStream.

at the create time, you can specify the encoding of the Reader:

InputStreamReader isr = new InputStreamReader(stream, "UTF-8");

then apply this Reader to the load method :

prop.load(isr);

BTW: get the stream from .properties file :

 InputStream stream = this.class.getClassLoader().getResourceAsStream("a.properties");

BTW: get resource bundle from InputStreamReader:

ResourceBundle rb = new PropertyResourceBundle(isr);

hope this can help you !

You can try using Scanner if you are using JDK5 or higher.

Scanner scan = new Scanner(file);  
scan.useDelimiter("\\Z");  
String content = scan.next(); 

Or you can also use Guava

String data = Files.toString(new File("path.txt"), Charsets.UTF8);

It may not be running.

try runnign /etc/init.d/asterisk status

If its not running, Start it using:

/etc/init.d/asterisk start

Or in RH 7:

Systemctl start asterisk

while loops check the condition before the loop, do...while loops check the condition after the loop. This is useful is you want to base the condition on side effects from the loop running or, like other posters said, if you want the loop to run at least once.

I understand where you're coming from, but the do-while is something that most use rarely, and I've never used myself. You're not doing it wrong.

You're not doing it wrong. That's like saying someone is doing it wrong because they've never used the byte primitive. It's just not that commonly used.

You could define a mapping of air pressure to servo angle, for example:

def calc_angle(pressure, min_p=1000, max_p=1200):     return 360 * ((pressure - min_p) / float(max_p - min_p))  angle = calc_angle(pressure) 

This will linearly convert pressure values between min_p and max_p to angles between 0 and 360 (you could include min_a and max_a to constrain the angle, too).

To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:

d = {1000:0, 1001: 1.8, ...}  angle = d[pressure] 

but this would be rather time-consuming to type out!

Current React Router Version 5.2.0

activeStyle is a default css property of NavLink component which is imported from react-router-dom

So that we can write our own custom css to make it active.In this example i made background transparent and text to be bold.And I store it on a constant named isActive

    import React from "react";
    import { NavLink} from "react-router-dom";

    function nav() {

          const isActive = {
            fontWeight: "bold",
            backgroundColor: "rgba(255, 255, 255, 0.1)",
          };
    
    return (
          <ul className="navbar-nav mr-auto">
            <li className="nav-item">
              <NavLink className="nav-link" to="/Shop" activeStyle={isActive}>
                Shop
              </NavLink>
            </li>
          </ul>
          );

    export default nav;

If you want to do this solely using javascript, I would do the following. Give the span an id attribute (so that it can easily be retrieved from the DOM) and place all the content in an attribute named 'content':

<span id='myDataId' style='text-overflow: ellipsis; overflow : hidden;
 white-space: nowrap; width: 71;' content='{$myData}'>${myData}</span>

Then, in your javascript, you can do the following after the element has been inserted into the DOM.

var elemInnerText, elemContent;
elemInnerText = document.getElementById("myDataId").innerText;
elemContent = document.getElementById("myDataId").getAttribute('content')
if(elemInnerText.length <= elemContent.length)
{
   document.getElementById("myDataId").setAttribute('title', elemContent); 
}

Of course, if you're using javascript to insert the span into the DOM, you could just keep the content in a variable before inserting it. This way you don't need a content attribute on the span.

There are more elegant solutions than this if you want to use jQuery.

If you're encoding a string to put in a URL component (a querystring parameter), you should call encodeURIComponent.

If you're encoding an existing URL, call encodeURI.

Don't use @@ERROR, use BEGIN TRY/BEGIN CATCH instead. See this article: Exception handling and nested transactions for a sample procedure:

create procedure [usp_my_procedure_name]
as
begin
    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

        -- Do the actual work here

lbexit:
        if @trancount = 0   
            commit;
    end try
    begin catch
        declare @error int, @message varchar(4000), @xstate int;
        select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
        if @xstate = -1
            rollback;
        if @xstate = 1 and @trancount = 0
            rollback
        if @xstate = 1 and @trancount > 0
            rollback transaction usp_my_procedure_name;

        raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
        return;
    end catch   
end

These options are suited for a development server. For a production server you should not display any error to the end user. So change the display flags to off.

Its a late answer, but as I can see most of the people mentioned about "refresh" method to redirect a webpage. As per W3C, we should not use "refresh" to redirect. Because it could break the "back" button. Imagine that the user presses the "back" button, the refresh would work again, and the user would bounce forward. The user will most likely get very annoyed, and close the window, which is probably not what you, as the author of this page, want.

Use HTTP redirects instead. One can refer the complete documentation here: W3C document

Method 1

Client : Send as JSON

$.ajax({
    url: 'example.com/ajax/',
    type: 'POST',
    contentType: 'application/json; charset=utf-8',
    processData: false,
    data: JSON.stringify({'name':'John', 'age': 42}),
    ...
});

//Sent as a JSON object {'name':'John', 'age': 42}

Server :

data = json.loads(request.body) # {'name':'John', 'age': 42}

Method 2

Client : Send as x-www-form-urlencoded
(Note: contentType & processData have changed, JSON.stringify is not needed)

$.ajax({
    url: 'example.com/ajax/',
    type: 'POST',    
    data: {'name':'John', 'age': 42},
    contentType: 'application/x-www-form-urlencoded; charset=utf-8',  //Default
    processData: true,       
});

//Sent as a query string name=John&age=42

Server :

data = request.POST # will be <QueryDict: {u'name':u'John', u'age': 42}>

Changed in 1.5+ : https://docs.djangoproject.com/en/dev/releases/1.5/#non-form-data-in-http-requests

Non-form data in HTTP requests :
request.POST will no longer include data posted via HTTP requests with non form-specific content-types in the header. In prior versions, data posted with content-types other than multipart/form-data or application/x-www-form-urlencoded would still end up represented in the request.POST attribute. Developers wishing to access the raw POST data for these cases, should use the request.body attribute instead.

Add a reference to the Microsoft Forms 2.0 Object Library and try this code. It only works with text, not with other data types.

Dim DataObj As New MSForms.DataObject

'Put a string in the clipboard
DataObj.SetText "Hello!"
DataObj.PutInClipboard

'Get a string from the clipboard
DataObj.GetFromClipboard
Debug.Print DataObj.GetText

Here you can find more details about how to use the clipboard with VBA.

You should use:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)  {
    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.ECLAIR
            && keyCode == KeyEvent.KEYCODE_BACK
            && event.getRepeatCount() == 0) {
        // Take care of calling this method on earlier versions of
        // the platform where it doesn't exist.
        onBackPressed();
    }

    return super.onKeyDown(keyCode, event);
}

@Override
public void onBackPressed() {
    // This will be called either automatically for you on 2.0
    // or later, or by the code above on earlier versions of the
    // platform.
    return;
}

As defined here: http://android-developers.blogspot.com/2009/12/back-and-other-hard-keys-three-stories.html

If you are using an older version to compile the code, replace android.os.Build.VERSION_CODES.ECLAIR by 5 (you can add a private int named ECLAIR for example)

If you happen to use DroidParts, I've just added ClearableEditText.

Here's what it looks like with a custom background & clear icon set to abs__ic_clear_holo_light from ActionBarSherlock:

you can use a Timer (System.Windows.Forms.Timer).

Hook it's Tick event, advance then progress bar until it reaches the max value. when it does (hit the max) and you didn't finish the job, reset the progress bar value back to minimum.

...just like Windows Explorer :-)

This maybe help somebody who is looking for the way to sort table by two columns, but in paralel way. This means to combine two sorts using aggregate sorting function. It's very useful when for example retrieving articles using fulltext search and also concerning the article publish date.

This is only example, but if you catch the idea you can find a lot of aggregate functions to use. You can even weight the columns to prefer one over second. The function of mine takes extremes from both sorts, thus the most valued rows are on the top.

Sorry if there exists simplier solutions to do this job, but I haven't found any.

SELECT
 `id`,
 `text`,
 `date`
 FROM
   (
   SELECT
     k.`id`,
     k.`text`,
     k.`date`,
     k.`match_order_id`,
     @row := @row + 1 as `date_order_id`
     FROM
     (
       SELECT
         t.`id`,
         t.`text`,
         t.`date`,
         @row := @row + 1 as `match_order_id`
         FROM
         (
           SELECT
             `art_id` AS `id`,
             `text`   AS `text`,
             `date`   AS `date`,
             MATCH (`text`) AGAINST (:string) AS `match`
             FROM int_art_fulltext
             WHERE MATCH (`text`) AGAINST (:string IN BOOLEAN MODE)
             LIMIT 0,101
         ) t,
         (
           SELECT @row := 0
         ) r
         ORDER BY `match` DESC
     ) k,
     (
       SELECT @row := 0
     ) l
     ORDER BY k.`date` DESC
   ) s
 ORDER BY (1/`match_order_id`+1/`date_order_id`) DESC

No comment on why you want to do this, or what might be a more standard practice: here is a solution to your question.... Keep in mind that the type of quotes required by your command line may vary.

In your db.js, export the init function. There are many ways, but for example:

module.exports.init = function () {
  console.log('hi');
};

Then call it like this, assuming your db.js is in the same directory as your command prompt:

node -e 'require("./db").init()'

To other readers, the OP's init function could have been called anything, it is not important, it is just the specific name used in the question.

It always best to start any custom PHP project with a bootstrap file where you define the most commonly used paths as constants, based on values extracted from $_SERVER. It should make migrating your projects or parts of your project to another server or to another directory on the server a hell of a lot easier.

This is how I define my root paths :

define("LOCAL_PATH_ROOT", $_SERVER["DOCUMENT_ROOT"]);
define("HTTP_PATH_ROOT", isset($_SERVER["HTTP_HOST"]) ? $_SERVER["HTTP_HOST"] : (isset($_SERVER["SERVER_NAME"]) ? $_SERVER["SERVER_NAME"] : '_UNKNOWN_'));

The path LOCAL_PATH_ROOT is the document root. The path HTTP_PATH_ROOT is the equivalent when accessing the same path via HTTP.

At that point, converting any local path to an HTTP path can be done with the following code :

str_replace(LOCAL_PATH_ROOT, RELATIVE_PATH_ROOT, $my_path)

If you want to ensure compatibility with Windows based servers, you'll need to replace the directory seperator with a URL seperator as well :

str_replace(LOCAL_PATH_ROOT, RELATIVE_PATH_ROOT, str_replace(DIRECTORY_SEPARATOR, '/', $my_path))

Here's the full bootstrap code that I'm using for the PHP PowerTools boilerplate :

I've seen it in coding standards for C++ that were a hang-over from C, as if you don't have RAII or other automatic memory management then you have to clean up for each return, which either means cut-and-paste of the clean-up or a goto (logically the same as 'finally' in managed languages), both of which are considered bad form. If your practices are to use smart pointers and collections in C++ or another automatic memory system, then there isn't a strong reason for it, and it become all about readability, and more of a judgement call.

foreach (ListItem item in CBLGold.Items)
{
    if (item.Selected)
    {
        string selectedValue = item.Value;
    }
}

You can use the return statement inside a stored procedure to return an integer status code (and only of integer type). By convention a return value of zero is used for success.

If no return is explicitly set, then the stored procedure returns zero.

   CREATE PROCEDURE GetImmediateManager
      @employeeID INT,
      @managerID INT OUTPUT
   AS
   BEGIN
     SELECT @managerID = ManagerID 
     FROM HumanResources.Employee 
     WHERE EmployeeID = @employeeID

     if @@rowcount = 0 -- manager not found?
       return 1;
   END

And you call it this way:

DECLARE @return_status int;
DECLARE @managerID int;

EXEC @return_status = GetImmediateManager 2, @managerID output;
if @return_status = 1
  print N'Immediate manager not found!';
else 
  print N'ManagerID is ' + @managerID;
go

You should use the return value for status codes only. To return data, you should use output parameters.

If you want to return a dataset, then use an output parameter of type cursor.

Besides all above solutions, check if you have the "id" or any custom defined parameter in the DELETE method is matching the route config.

public void Delete(int id)
{
 //some code here
}

If you hit with repeated 405 errors better reset the method signature to default as above and try.

The route config by default will look for id in the URL. So the parameter name id is important here unless you change the route config under App_Start folder.

You may change the data type of the id though.

For example the below method should work just fine:

public void Delete(string id)
{
 //some code here
}

Note: Also ensure that you pass the data over the url not the data method that will carry the payload as body content.

DELETE http://{url}/{action}/{id}

Example:

DELETE http://localhost/item/1

Hope it helps.

Try the keyboard shortcut Ctrl-Shift-Space. This corresponds to Edit.ParameterInfo, in case you've changed the default.

Example:

This is possible to do without an iframe specifically. jQuery is utilised since it's mentioned in the title.

File -> Open projects from File System

I firstly recommend you to read Hannes Dorfmann's great article about this topic.

When new view type comes, you have to edit your adapter and you have to handle so many mess things. Your adapter should be Open for extension but Closed for modification.

You may check this two project, they can give the idea about how to handle different ViewTypes in Adapter:

Here is a solution that defines a git alias, so you will be able use it like that :

git rblame -M -n -L '/REGEX/,+1' FILE

Output example :

00000000 18 (Not Committed Yet 2013-08-19 13:04:52 +0000 728) fooREGEXbar
15227b97 18 (User1 2013-07-11 18:51:26 +0000 728) fooREGEX
1748695d 23 (User2 2013-03-19 21:09:09 +0000 741) REGEXbar

You can define the alias in your .gitconfig or simply run the following command

git config alias.rblame !sh -c 'while line=$(git blame "$@" $commit 2>/dev/null); do commit=${line:0:8}^; [ 00000000^ == $commit ] && commit=$(git rev-parse HEAD); echo $line; done' dumb_param

This is an ugly one-liner, so here is a de-obfuscated equivalent bash function :

git-rblame () {
    local commit line
    while line=$(git blame "$@" $commit 2>/dev/null); do
        commit="${line:0:8}^"
        if [ "00000000^" == "$commit" ]; then
            commit=$(git rev-parse HEAD)
        fi
        echo $line
    done
}

The pickaxe solution ( git log --pickaxe-regex -S'REGEX' ) will only give you line additions/deletions, not the other alterations of the line containing the regular expression.

A limitation of this solution is that git blame only returns the 1st REGEX match, so if multiple matches exist the recursion may "jump" to follow another line. Be sure to check the full history output to spot those "jumps" and then fix your REGEX to ignore the parasite lines.

Finally, here is an alternate version that run git show on each commit to get the full diff :

git config alias.rblameshow !sh -c 'while line=$(git blame "$@" $commit 2>/dev/null); do commit=${line:0:8}^; [ 00000000^ == $commit ] && commit=$(git rev-parse HEAD); git show $commit; done' dumb_param

As the others have mentioned, useState works - here is how mobx-react-lite implements updates - you could do something similar.

Define a new hook, useForceUpdate -

import { useState, useCallback } from 'react'

export function useForceUpdate() {
  const [, setTick] = useState(0);
  const update = useCallback(() => {
    setTick(tick => tick + 1);
  }, [])
  return update;
}

and use it in a component -

const forceUpdate = useForceUpdate();
if (...) {
  forceUpdate(); // force re-render
}

See https://github.com/mobxjs/mobx-react-lite/blob/master/src/utils.ts and https://github.com/mobxjs/mobx-react-lite/blob/master/src/useObserver.ts

I had a scenario where nested JSON had to be serialised in a linear fashion while form data is constructed, since this is how server expects values. So, I wrote a small recursive function which translates the JSON which is like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress":{
      "city":"Wonderland",
      "code":"8796682911767",
      "firstname":"Raj Pawan",
      "lastname":"Gumdal",
      "line1":"Addr Line 1",
      "line2":null,
      "state":"US-AS",
      "region":{
         "isocode":"US-AS"
      },
      "zip":"76767-6776"
   }
}

Into something like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress.city":"Wonderland",
   "billingAddress.code":"8796682911767",
   "billingAddress.firstname":"Raj Pawan",
   "billingAddress.lastname":"Gumdal",
   "billingAddress.line1":"Addr Line 1",
   "billingAddress.line2":null,
   "billingAddress.state":"US-AS",
   "billingAddress.region.isocode":"US-AS",
   "billingAddress.zip":"76767-6776"
}

The server would accept form data which is in this converted format.

Here is the function:

function jsonToFormData (inJSON, inTestJSON, inFormData, parentKey) {
    // http://stackoverflow.com/a/22783314/260665
    // Raj: Converts any nested JSON to formData.
    var form_data = inFormData || new FormData();
    var testJSON = inTestJSON || {};
    for ( var key in inJSON ) {
        // 1. If it is a recursion, then key has to be constructed like "parent.child" where parent JSON contains a child JSON
        // 2. Perform append data only if the value for key is not a JSON, recurse otherwise!
        var constructedKey = key;
        if (parentKey) {
            constructedKey = parentKey + "." + key;
        }

        var value = inJSON[key];
        if (value && value.constructor === {}.constructor) {
            // This is a JSON, we now need to recurse!
            jsonToFormData (value, testJSON, form_data, constructedKey);
        } else {
            form_data.append(constructedKey, inJSON[key]);
            testJSON[constructedKey] = inJSON[key];
        }
    }
    return form_data;
}

Invocation:

        var testJSON = {};
        var form_data = jsonToFormData (jsonForPost, testJSON);

I am using testJSON just to see the converted results since I would not be able to extract the contents of form_data. AJAX post call:

        $.ajax({
            type: "POST",
            url: somePostURL,
            data: form_data,
            processData : false,
            contentType : false,
            success: function (data) {
            },
            error: function (e) {
            }
        });

Something like this ought to do:

$url = preg_replace("|^.+?://|", "", $url); 

Removes everything up to and including the ://

First you need to think off when you want to swap. For example you could switch everytime when its a div tag thats loaded. In my example i just used a extra data field "background" and whenever its set the image is applied as a background image.

Then you just have to load the Data with the created image tag. And not overwrite the img tag instead apply a css background image.

Here is a example of the code change:

if (settings.appear) {
    var elements_left = elements.length;
    settings.appear.call(self, elements_left, settings);
}
var loadImgUri;
if($self.data("background"))
    loadImgUri = $self.data("background");
else
    loadImgUri  = $self.data(settings.data_attribute);

$("<img />")
    .bind("load", function() {
        $self
            .hide();
        if($self.data("background")){
            $self.css('backgroundImage', 'url('+$self.data("background")+')');
        }else
            $self.attr("src", $self.data(settings.data_attribute))

        $self[settings.effect](settings.effect_speed);

        self.loaded = true;

        /* Remove image from array so it is not looped next time. */
        var temp = $.grep(elements, function(element) {
            return !element.loaded;
        });
        elements = $(temp);

        if (settings.load) {
            var elements_left = elements.length;
            settings.load.call(self, elements_left, settings);
        }
    })
    .attr("src", loadImgUri );
}

the loading stays the same

$("#divToLoad").lazyload();

and in this example you need to modify the html code like this:

<div data-background="http://apod.nasa.gov/apod/image/9712/orionfull_jcc_big.jpg" id="divToLoad" />?

but it would also work if you change the switch to div tags and then you you could work with the "data-original" attribute.

Here's an fiddle example: http://jsfiddle.net/dtm3k/1/

If you want to content to be scrollable, set the position of the content to absolute:

content {
   position: absolute;
   ...
}

I don't know if this was just for me, but if not that's the fix!

Also since the background is fixed, it means you have a "parallax" effect! So now, not only did this person teach you how to make a blurry background, but it is also a parallax background effect!

Using the example data set that Ananda dummied up, here's an example using aggregate(), which is part of core R. aggregate() just needs something to count as function of the different values of MONTH-YEAR. In this case, I used VALUE as the thing to count:

aggregate(cbind(count = VALUE) ~ MONTH.YEAR, 
          data = mydf, 
          FUN = function(x){NROW(x)})

which gives you..

  MONTH.YEAR count
1  FEB. 2012     2
2  JAN. 2012     2
3  MAR. 2012     1

I had the same error message. For me it was happening because I was trying to run the installer from the DVD rather than running the installer from Add/Remove programs.

In addition to above answers suggesting (1) the modification of the configuration files pg_hba.conf and (2) postgresql.conf and (3) restarting the PostgreSQL service, some Windows computers might also require incoming TCP traffic to be allowed on the port (usually 5432).

To do this, you would need to open Windows Firewall and add an inbound rule for the port (e.g. 5432).

Head to Control Panel\System and Security\Windows Defender Firewall > Advanced Settings > Actions (right tab) > Inbound Rules > New Rule… > Port > Specific local ports and type in the port your using, usually 5432 > (defaults settings for the rest and type any name you'd like)

Now, try connecting again from pgAdmin on the client computer. Restarting the service is not required.

A great substitute for np.isnan() and pd.isnull() is

for i in range(0,a.shape[0]):
    if(a[i]!=a[i]):
       //do something here
       //a[i] is nan

since only nan is not equal to itself.

If you are using Windows, open up a command prompt and type 'netstat -an'.

If your server is running, you should be able to see the port 1883.

If you cannot go to Task Manager > Services and start/restart the Mosquitto server from there. If you cannot find it here too, your installation of Mosquitto has not been successful.

A more detailed tutorial for setting up Mosquitto with Windows / is linked here.

I use to use the Do, Loop a lot but I have started using a Sub or a Function that I could exit out of instead. It just seemed cleaner to me. If any variables you need are not global you will need to pass them to the Sub also.

For i=1 to N
 DoWork i
Next

Sub DoWork(i)
    [Code]
    If Condition1 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

    [...]
End Sub

To make it simpler to follow, I will summarize the above answers:

Let`s say the table is called Customer it has 4 columns/less or more...

you want to add a new column to the table where every time when there is insert... then that column keeps a record of the time the event happened.

Solution:

add a new column, let`s say timepurchase is the new column, to the table with data type datetime.

Then run the following alter:

ALTER TABLE Customer ADD CONSTRAINT DF_Customer DEFAULT GETDATE() FOR timePurchase

From the dplyr package you can also use the mutate_all() function in combination with toupper(). This will affect both character and factor classes.

library(dplyr)
df <- mutate_all(df, funs=toupper)

var myNumber: number = 1200;_x000D_
//convert to hexadecimal value_x000D_
console.log(myNumber.toString(16)); //will return  4b0_x000D_
//Other way of converting to hexadecimal_x000D_
console.log(Math.abs(myNumber).toString(16)); //will return  4b0_x000D_
//convert to decimal value_x000D_
console.log(parseFloat(myNumber.toString()).toFixed(2)); //will return  1200.00

You could try something like this:

echo 'maps.google.com' | rev | cut -d'.' -f 1 | rev

Explanation

• rev reverses "maps.google.com" to be moc.elgoog.spam
• cut uses dot (ie '.') as the delimiter, and chooses the first field, which is moc
• lastly, we reverse it again to get com

$(document).ready(function() {
    //set initial state.
    $('#textbox1').val($(this).is(':checked'));

    $('#checkbox1').change(function() {
        $('#textbox1').val($(this).is(':checked'));
    });

    $('#checkbox1').click(function() {
        if (!$(this).is(':checked')) {
            if(!confirm("Are you sure?"))
            {
                $("#checkbox1").prop("checked", true);
                $('#textbox1').val($(this).is(':checked'));
            }
        }
    });
});

You can run that script as a service, restart every 30 seconds

I tried all the solutions above and in addition, those in related answers as well. Solutions including but not limited to passing the blob manually to a HTMLInputElement's file property, calling all the readAs* methods on FileReader, using a File instance as second argument for a FormData.append call, trying to get the blob data as a string by getting the values at URL.createObjectURL(myBlob) which turned out nasty and crashed my machine.

Now, if you happen to attempt those or more and still find you're unable to upload your blob, it could mean the problem is server-side. In my case, my blob exceeded the http://www.php.net/manual/en/ini.core.php#ini.upload-max-filesize and post_max_size limit in PHP.INI so the file was leaving the front end form but getting rejected by the server. You could either increase this value directly in PHP.INI or via .htaccess

The only reason to have a return in a void function would be to exit early due to some conditional statement:

void foo(int y)
{
    if(y == 0) return;

    // do stuff with y
}

As unwind said: when the code ends, it ends. No need for an explicit return at the end.

My Python version is Python 3.5.2 and the solution proposed in the accepted answer didn't work for me. I've still were given an error

FileNotFoundError: [Errno 2] No such file or directory

when I was running my_script.py from the terminal. Although it worked fine when I run it through Run/Debug Configurations from PyCharm IDE (PyCharm 2018.3.2 (Community Edition)).

Solution:

instead of using:

my_path = os.path.abspath(os.path.dirname(__file__)) + some_rel_dir_path 

as suggested in the accepted answer, I used:

my_path = os.path.abspath(os.path.dirname(os.path.abspath(__file__))) + some_rel_dir_path

Explanation: Changing os.path.dirname(__file__) to os.path.dirname(os.path.abspath(__file__)) solves the following problem:

When we run our script like that: python3 my_script.py the __file__ variable has a just a string value of "my_script.py" without path leading to that particular script. That is why method dirname(__file__) returns an empty string "". That is also the reson why my_path = os.path.abspath(os.path.dirname(__file__)) + some_rel_dir_path is actually the same thing as my_path = some_rel_dir_path. Consequently FileNotFoundError: [Errno 2] No such file or directory is given when trying to use open method because there is no directory like "some_rel_dir_path".

Running script from PyCharm IDE Running/Debug Configurations worked because it runs a command python3 /full/path/to/my_script.py (where "/full/path/to" is specified by us in "Working directory" variable in Run/Debug Configurations) instead of justpython3 my_script.py like it is done when we run it from the terminal.

Hope that will be useful.

No, this is not possible. In documents that make use of CSS, an inline style attribute can only contain property declarations; the same set of statements that appears in each ruleset in a stylesheet. From the Style Attributes spec:

The value of the style attribute must match the syntax of the contents of a CSS declaration block (excluding the delimiting braces), whose formal grammar is given below in the terms and conventions of the CSS core grammar:

declaration-list
  : S* declaration? [ ';' S* declaration? ]*
  ;

Neither selectors (including pseudo-elements), nor at-rules, nor any other CSS construct are allowed.

Think of inline styles as the styles applied to some anonymous super-specific ID selector: those styles only apply to that one very element with the style attribute. (They take precedence over an ID selector in a stylesheet too, if that element has that ID.) Technically it doesn't work like that; this is just to help you understand why the attribute doesn't support pseudo-class or pseudo-element styles (it has more to do with how pseudo-classes and pseudo-elements provide abstractions of the document tree that can't be expressed in the document language).

Note that inline styles participate in the same cascade as selectors in rule sets, and take highest precedence in the cascade (!important notwithstanding). So they take precedence even over pseudo-class states. Allowing pseudo-classes or any other selectors in inline styles would possibly introduce a new cascade level, and with it a new set of complications.

Note also that very old revisions of the Style Attributes spec did originally propose allowing this, however it was scrapped, presumably for the reason given above, or because implementing it was not a viable option.

'[{"event":"inbound","ts":1426249238}]' is a string, you cannot access any properties there. You will have to parse it to an object, with JSON.parse() and then handle it like a normal object

Maybe it is simple, try this if you have a DataFrame. then make sure that both matrices or vectros that you're trying to combine have the same rows_name/index

I had the same issue. I changed the name indices of the rows to make them match each other here is an example for a matrix (principal component) and a vector(target) have the same row indicies (I circled them in the blue in the leftside of the pic)

Before, "when it was not working", I had the matrix with normal row indicies (0,1,2,3) while I had the vector with row indices (ID0, ID1, ID2, ID3) then I changed the vector's row indices to (0,1,2,3) and it worked for me.

Jquery 3.0 has some breaking changes that remove certain methods due to conflicts. Your error is most likely due to one of these changes such as the removal of the .load() event.

Read more in the jQuery Core 3.0 Upgrade Guide

To fix this you either need to rewrite the code to be compatible with Jquery 3.0 or else you can use the JQuery Migrate plugin which restores the deprecated and/or removed APIs and behaviours.

In case of ActionLink, it generally uses HttpUtility.Encode on the link text. In that case you can use HttpUtility.HtmlDecode(myString) it worked for me when using HtmlActionLink to decode the string that I wanted to pass. eg:

The current windows installer from nodejs.org as of v0.6.11 (2012-02-20) will install NPM along with NodeJS.

NOTES:

• At this point, the 64-bit version is your best bet
• The install path for 32-bit node is "Program Files (x86)" in 64-bit windows.
• You may also need to add quotes to the path statement in environment variables, this only seems to be in some cases that I've seen.
• In Windows, the global install path is actually in your user's profile directory
  • %USERPROFILE%\AppData\Roaming\npm
  • %USERPROFILE%\AppData\Roaming\npm-cache
  • WARNING: If you're doing timed events or other automation as a different user, make sure you run npm install as that user. Some modules/utilities should be installed globally.
  • INSTALLER BUGS: You may have to create these directories or add the ...\npm directory to your users path yourself.

To change the "global" location for all users to a more appropriate shared global location %ALLUSERSPROFILE%\(npm|npm-cache) (do this as an administrator):

• create an [NODE_INSTALL_PATH]\etc\ directory
  • this is needed before you try npm config --global ... actions
• create the global (admin) location(s) for npm modules
  • C:\ProgramData\npm-cache - npm modules will go here
  • C:\ProgramData\npm - binary scripts for globally installed modules will go here
  • C:\ProgramData\npm\node_modules - globally installed modules will go here
  • set the permissions appropriately
    • administrators: modify
    • authenticated users: read/execute
• Set global configuration settings (Administrator Command Prompt)
  • npm config --global set prefix "C:\ProgramData\npm"
  • npm config --global set cache "C:\ProgramData\npm-cache"
• Add C:\ProgramData\npm to your System's Path environment variable

If you want to change your user's "global" location to %LOCALAPPDATA%\(npm|npm-cache) path instead:

• Create the necessary directories
  • C:\Users\YOURNAME\AppData\Local\npm-cache - npm modules will go here
  • C:\Users\YOURNAME\AppData\Local\npm - binary scripts for installed modules will go here
  • C:\Users\YOURNAME\AppData\Local\npm\node_modules - globally installed modules will go here
• Configure npm
  • npm config set prefix "C:\Users\YOURNAME\AppData\Local\npm"
  • npm config set cache "C:\Users\YOURNAME\AppData\Local\npm-cache"
• Add the new npm path to your environment's PATH.
  • setx PATH "%PATH%;C:\Users\YOURNAME\AppData\Local\npm"

For beginners, some of the npm modules I've made the most use of are as follows.

• axios - for more complex http posts/gets
• isomorphic-fetch - for http(s) post/get requests
• node-mailer - smtp client
• mssql - interface and driver library for querying MS SQL Server (wraps tedious)

More advanced JS options...

• async/await - async functions, supported via babel

For testing, I reach for the following tools...

• mocha - testing framework
• chai - assertion library, I like chai.expect
• sinon - spies and stubs and shims
• sinon-chai - extend chai with sinon's assertion tools
• babel-istanbul - coverage reports
• jest - parallel testing, assertions, mocking, coverage reports in one tool
• babel-plugin-rewire - slightly easier for some mocking conditions vs. jest

Web tooling.

• webpack - module bundler, package node-style modules for browser usage
• babel - convert modern JS (ES2015+) syntax for your deployment environment.

If you build it...

• shelljs - shell utilities for node scripts,. I used to use gulp/grunt, but these days will have a scripts directory that's referenced in package.json scripts via npm. You can use gulp tools inside plain scripts.

Java (at least 5 and 6, java 7 Paths solved most) has a problem with UNC and URI. Eclipse team wrapped it up here : http://wiki.eclipse.org/Eclipse/UNC_Paths

From java.io.File javadocs, the UNC prefix is "////", and java.net.URI handles file:////host/path (four slashes).

More details on why this happens and possible problems it causes in other URI and URL methods can be found in the list of bugs at the end of the link given above.

Using these informations, Eclipse team developed org.eclipse.core.runtime.URIUtil class, which source code can probably help out when dealing with UNC paths.

head or tail can do it as well:

head -c X

Prints the first X bytes (not necessarily characters if it's a UTF-16 file) of the file. tail will do the same, except for the last X bytes.

This (and cut) are portable.

Having seen simply too many edge cases, I went for a simpler check:

^(([0-9\ \+\_\-\,\.\^\*\?\$\^\#\(\)])|(ext|x)){1,20}$

The first thing one may point out is allowing repetition of "ext", but the purpose of this regex is to prevent users from accidentally entering email ids etc. instead of phone numbers, which it does.

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

Additional Resources:

• Configure PersistentVolume Guide

I think you want to print the name of the person or both the name and email :

const renObjData = this.props.data.map(function(data, idx) {
    return <p key={idx}>{data.name}</p>;
});

or :

const renObjData = this.props.data.map(function(data, idx) {
   return ([
       <p key={idx}>{data.name}</p>,
       <p key={idx}>{data.email}</p>,
   ]);
});

You can use [Adjacent sibling combinators] as described in the W3 CSS Selectors Recommendation1 So you can use a + sign (or even a ~ tilde) apply a padding to the nested ul tag, as you described in your question and you'll get the result you need. I also think what you want it to override the main css, locally. You can do this:

<style>
    li+ul {padding-left: 20px;}
</style>

This way the inner ul will be nested including the bullets of the li elements. I wish this was helpful! =)

This worked for me too. Later, I ended-up switching to the maven-antrun-plugin to avoid warnings in Eclipse. And I prefer using default plugins when possible. Example:

<plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>3.0.0</version>
    <executions>
        <execution>
            <id>get-the-hostname</id>
            <phase>package</phase>
            <configuration>
                <target>
                    <exec executable="bash">
                        <arg value="-c"/>
                        <arg value="hostname"/>
                    </exec>
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Another way in addition to the ones provided here for ES6

module.exports = class TEST{
    constructor(size) {
        this.map = new MAp();
        this.size = size;

    }

    get(key) {
        return this.map.get(key);
    }

    length() {
        return this.map.size;
    }    

}

and include the same as

var TEST= require('./TEST');
var test = new TEST(1);

A big part of the REST philosophy is to exploit as many standard features of the HTTP protocol as possible when designing your API. Applying that philosophy to authentication, client and server would utilize standard HTTP authentication features in the API.

Login screens are great for human user use cases: visit a login screen, provide user/password, set a cookie, client provides that cookie in all future requests. Humans using web browsers can't be expected to provide a user id and password with each individual HTTP request.

But for a REST API, a login screen and session cookies are not strictly necessary, since each request can include credentials without impacting a human user; and if the client does not cooperate at any time, a 401 "unauthorized" response can be given. RFC 2617 describes authentication support in HTTP.

TLS (HTTPS) would also be an option, and would allow authentication of the client to the server (and vice versa) in every request by verifying the public key of the other party. Additionally this secures the channel for a bonus. Of course, a keypair exchange prior to communication is necessary to do this. (Note, this is specifically about identifying/authenticating the user with TLS. Securing the channel by using TLS / Diffie-Hellman is always a good idea, even if you don't identify the user by its public key.)

An example: suppose that an OAuth token is your complete login credentials. Once the client has the OAuth token, it could be provided as the user id in standard HTTP authentication with each request. The server could verify the token on first use and cache the result of the check with a time-to-live that gets renewed with each request. Any request requiring authentication returns 401 if not provided.

I found this to work best for me https://jsfiddle.net/Lu92akv6/ [I found this to work for me try this fiddle][1]

In API level 29, WifiManager.enableNetwork() method is deprecated. As per Android API documentation(check here):

1. See WifiNetworkSpecifier.Builder#build() for new mechanism to trigger connection to a Wi-Fi network.
2. See addNetworkSuggestions(java.util.List), removeNetworkSuggestions(java.util.List) for new API to add Wi-Fi networks for consideration when auto-connecting to wifi. Compatibility Note: For applications targeting Build.VERSION_CODES.Q or above, this API will always return false.

From API level 29, to connect to WiFi network, you will need to use WifiNetworkSpecifier. You can find example code at https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier.Builder.html#build()

This will do the trick!

div {
  height: 100vh;

I'm surprised nobody has mentioned explicit conversion flag yet

>>> print('{!r}'.format('a word that needs quotation marks'))
'a word that needs quotation marks'

The flag !r is a shorthand of the repr() built-in function¹. It is used to print the object representation object.__repr__() instead of object.__str__().

There is an interesting side-effect though:

>>> print("{!r} \t {!r} \t {!r} \t {!r}".format("Buzz'", 'Buzz"', "Buzz", 'Buzz'))
"Buzz'"      'Buzz"'     'Buzz'      'Buzz'

Notice how different composition of quotation marks are handled differenty so that it fits a valid string representation of a Python object ².

^{1 Correct me if anybody knows otherwise.}

^{2 The question's original example " "word" " is not a valid representation in Python}

Look at this complete example https://github.com/marcindulak/python-mycli of a small python package. It is based on packaging recommendations from https://packaging.python.org/en/latest/distributing.html, uses setup.py with distutils and in addition shows how to create RPM and deb packages.

The project's setup.py is included below (see the repo for the full source):

        if '__init__.py' in filenames:

package_dir = {name: name}

# Data files used e.g. in tests
package_data = {name: [os.path.join(name, 'tests', 'prt.txt')]}

# The current version number - MSI accepts only version X.X.X

# Provide bat executables in the tarball (always for Win)
if 'sdist' in sys.argv or os.name in ['ce', 'nt']:
    for s in scripts[:]:
        scripts.append(s + '.bat')

        fileslist = []
        for filename in filenames:
            fullname = os.path.join(dirname, filename)

* Wed Jan 14 2015 Marcin Dulak <[email protected]> - 0.0.1-1
- initial version

I was not actually able to render an image without borders or axis data based on any of the code snippets here (even the one accepted at the answer). After digging through some API documentation, I landed on this code to render my image

plt.axis('off')
plt.tick_params(axis='both', left='off', top='off', right='off', bottom='off', labelleft='off', labeltop='off', labelright='off', labelbottom='off')
plt.savefig('foo.png', dpi=100, bbox_inches='tight', pad_inches=0.0)

I used the tick_params call to basically shut down any extra information that might be rendered and I have a perfect graph in my output file.

Try to login via the terminal using the following command:

mysql -u root -p

It will then prompt for your password. If this fails, then definitely the username or password is incorrect. If this works, then your database's password needs to be enclosed in quotes:

database_password: "0000"

var bs []byte
value, _ := strconv.ParseInt(string(bs), 10, 64)

The SQL command is:

ALTER TABLE <tablename> ADD CONSTRAINT
            <constraintname> UNIQUE NONCLUSTERED
    (
                <columnname>
    )

See the full syntax here.

If you want to do it from a Database Diagram:

• right-click on the table and select 'Indexes/Keys'
• click the Add button to add a new index
• enter the necessary info in the Properties on the right hand side:
  • the columns you want (click the ellipsis button to select)
  • set Is Unique to Yes
  • give it an appropriate name

If the first item is to be used as a placeholder (empty value) and your select is required then you can use the :invalid pseudo-class to target it.

select {_x000D_
  -webkit-appearance: menulist-button;_x000D_
  color: black;_x000D_
}_x000D_
_x000D_
select:invalid {_x000D_
  color: green;_x000D_
}

<select required>_x000D_
  <option value="">Item1</option>_x000D_
  <option value="Item2">Item2</option>_x000D_
  <option value="Item3">Item3</option>_x000D_
</select>

<button onclick=location=URL>Refresh</button>

Small hack.

Just lose the parenthesis:

var nameslist = new List<string> { "one", "two", "three" };

One possible solution is do the concatenation manually, here is some useful code:

import json
def append_to_json(_dict,path): 
    with open(path, 'ab+') as f:
        f.seek(0,2)                                #Go to the end of file    
        if f.tell() == 0 :                         #Check if file is empty
            f.write(json.dumps([_dict]).encode())  #If empty, write an array
        else :
            f.seek(-1,2)           
            f.truncate()                           #Remove the last character, open the array
            f.write(' , '.encode())                #Write the separator
            f.write(json.dumps(_dict).encode())    #Dump the dictionary
            f.write(']'.encode())                  #Close the array

You should be careful when editing the file outside the script not add any spacing at the end.

I'd suggest avoiding in-line JavaScript:

var aElems = document.getElementsByTagName('a');

for (var i = 0, len = aElems.length; i < len; i++) {
    aElems[i].onclick = function() {
        var check = confirm("Are you sure you want to leave?");
        if (check == true) {
            return true;
        }
        else {
            return false;
        }
    };
}?

JS Fiddle demo.

The above updated to reduce space, though maintaining clarity/function:

var aElems = document.getElementsByTagName('a');

for (var i = 0, len = aElems.length; i < len; i++) {
    aElems[i].onclick = function() {
        return confirm("Are you sure you want to leave?");
    };
}

JS Fiddle demo.

A somewhat belated update, to use addEventListener() (as suggested, by bažmegakapa, in the comments below):

function reallySure (event) {
    var message = 'Are you sure about that?';
    action = confirm(message) ? true : event.preventDefault();
}
var aElems = document.getElementsByTagName('a');

for (var i = 0, len = aElems.length; i < len; i++) {
    aElems[i].addEventListener('click', reallySure);
}

JS Fiddle demo.

The above binds a function to the event of each individual link; which is potentially quite wasteful, when you could bind the event-handling (using delegation) to an ancestor element, such as the following:

function reallySure (event) {
    var message = 'Are you sure about that?';
    action = confirm(message) ? true : event.preventDefault();
}

function actionToFunction (event) {
    switch (event.target.tagName.toLowerCase()) {
        case 'a' :
            reallySure(event);
            break;
        default:
            break;
    }
}

document.body.addEventListener('click', actionToFunction);

JS Fiddle demo.

Because the event-handling is attached to the body element, which normally contains a host of other, clickable, elements I've used an interim function (actionToFunction) to determine what to do with that click. If the clicked element is a link, and therefore has a tagName of a, the click-handling is passed to the reallySure() function.

You can easily customize the android Navigation drawer once you know how its implemented. here is a nice tutorial where you can set it up.

This will be the structure of your mainXML:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Listview to display slider menu -->
    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"        
        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>

You can customize this listview to your liking by adding the header. And radiobuttons.

What you want is not possible. You have to create two parameters, and bind them separately:

select p from Person p where p.forename = :forename and p.surname = :surname
...
query.setParameter("forename", name.getForename());
query.setParameter("surname", name.getSurname());

Thanks, this was very helpful. I also wanted something that would link things that looked like a URL -- as a basic requirement, it'd link something like www.yahoo.com, even if the http:// protocol prefix was not present. So basically, if "www." is present, it'll link it and assume it's http://. I also wanted emails to turn into mailto: links. EXAMPLE: www.yahoo.com would be converted to www.yahoo.com

Here's the code I ended up with (combination of code from this page and other stuff I found online, and other stuff I did on my own):

function Linkify(inputText) {
    //URLs starting with http://, https://, or ftp://
    var replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim;
    var replacedText = inputText.replace(replacePattern1, '<a href="$1" target="_blank">$1</a>');

    //URLs starting with www. (without // before it, or it'd re-link the ones done above)
    var replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim;
    var replacedText = replacedText.replace(replacePattern2, '$1<a href="http://$2" target="_blank">$2</a>');

    //Change email addresses to mailto:: links
    var replacePattern3 = /(\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,6})/gim;
    var replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>');

    return replacedText
}

In the 2nd replace, the (^|[^/]) part is only replacing www.whatever.com if it's not already prefixed by // -- to avoid double-linking if a URL was already linked in the first replace. Also, it's possible that www.whatever.com might be at the beginning of the string, which is the first "or" condition in that part of the regex.

This could be integrated as a jQuery plugin as Jesse P illustrated above -- but I specifically wanted a regular function that wasn't acting on an existing DOM element, because I'm taking text I have and then adding it to the DOM, and I want the text to be "linkified" before I add it, so I pass the text through this function. Works great.

You can make another class for doing this kind of activities.

public class Go {

   public void Setting(Context context)
    {
        Intent intent = new Intent(android.provider.Settings.ACTION_SETTINGS);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(intent);
    }
}

In the package explorer and the navigation screen you should now see the project you created. Note that eclipse will not copy your files, it will just allow you to use the existing source and edit it from eclipse.

For Swift 4:

@IBAction func myButton(sender: AnyObject) {
    sender.titleLabel?.textAlignment = NSTextAlignment.center
    sender.setTitle("Some centered String", for:UIControlState.normal)
}

The name of an array is the address of its first element, so name is a pointer to memory containing the string "siva".

Also you don't need a pointer to display a character; you are just electing to use it directly from the array in this case. You could do this instead:

char c = *name;
printf("%c\n", c);

If the data is in an UTF-8 compatible format, you can convert the bytes to a string.

>>> import curses
>>> print(str(curses.version, "utf-8"))
2.2

Optionally convert to hex first, if the data is not already UTF-8 compatible. E.g. when the data are actual raw bytes.

from binascii import hexlify
from codecs import encode  # alternative
>>> print(hexlify(b"\x13\x37"))
b'1337'
>>> print(str(hexlify(b"\x13\x37"), "utf-8"))
1337
>>>> print(str(encode(b"\x13\x37", "hex"), "utf-8"))
1337

Another Alternative for those who are probing around and/or in interactive mode:

$Error[0].Exception.LoaderExceptions

Note: [0] grabs the most recent Error from the stack

One more thing needed for my setup was to add

172.17.0.1  localhost

to /etc/hosts

so that Docker would point to 172.17.0.1 as the DB hostname, and not rely on a changing outer ip to find the DB. Hope this helps someone else with this issue!

Check your BuildPath, it could be that you are referencing a library that does not exist anymore.

You want to use:

Collections.<String>emptyList();

If you look at the source for what emptyList does you see that it actually just does a

return (List<T>)EMPTY_LIST;

As pointed out already, most standard implementations of List are serializable. However you have to ensure that the objects referenced/contained within the list are also serializable.

Most of the time you would create a list in groovy rather than an array. You could do it like this:

names = ["lucas", "Fred", "Mary"]

Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:

names = "lucas Fred Mary".split()

If you are working from a windows forms application this worked for me

"server=localhost; user id=dbuser; password=password; database=dbname; Use Procedure Bodies=false;"

Just add the "Use Procedure Bodies=false" at the end of your connection string.

I too got the similar problem and I did like below..
Rt click the project, navigate to Run As --> click 6 Maven Clean and your build will be success..

if the other div is sibling/child, or any combination of, of the parent yes

    .showme{ _x000D_
        display: none;_x000D_
    }_x000D_
    .showhim:hover .showme{_x000D_
        display : block;_x000D_
    }_x000D_
    .showhim:hover .hideme{_x000D_
        display : none;_x000D_
    }_x000D_
    .showhim:hover ~ .hideme2{ _x000D_
        display:none;_x000D_
    }

    <div class="showhim">_x000D_
        HOVER ME_x000D_
        <div class="showme">hai</div> _x000D_
        <div class="hideme">bye</div>_x000D_
    </div>_x000D_
    <div class="hideme2">bye bye</div>

Accepted answer is outdated.

If you use MySQL 5.5.3+, use utf8mb4_unicode_ci instead of utf8_unicode_ci to ensure the characters typed by your users won't give you errors.

utf8mb4 supports emojis for example, whereas utf8 might give you hundreds of encoding-related bugs like:

Incorrect string value: ‘\xF0\x9F\x98\x81…’ for column ‘data’ at row 1

.myDiv {
    background-color: red;
    width: 100%;
    min-height: 100vh;
    max-height: 100%;
    position: absolute;
    top: 0;
    left: 0;
    margin: 0 auto;
}

Basically, we're fixing the div's position regardless of it's parent, and then position it using margin: 0 auto; and settings its position at the top left corner.

MagicTextView is very useful to make stroke font, but in my case, it cause error like this this error caused by duplication background attributes which set by MagicTextView

so you need to edit attrs.xml and MagicTextView.java

attrs.xml

<attr name="background" format="reference|color" />
 ?
<attr name="mBackground" format="reference|color" />

MagicTextView.java 88:95

if (a.hasValue(R.styleable.MagicTextView_mBackground)) {
Drawable background = a.getDrawable(R.styleable.MagicTextView_mBackground);
if (background != null) {
    this.setBackgroundDrawable(background);
} else {
    this.setBackgroundColor(a.getColor(R.styleable.MagicTextView_mBackground, 0xff000000));
}
}

That question solved a quite similar question for me and I thought I should share :

In raw python you can use sum() to count True values in a list :

>>> sum([True,True,True,False,False])
3

But this won't work :

>>> sum([[False, False, True], [True, False, True]])
TypeError...

I think you mean the active state

 button:active{
  //some styling
 }

These are all the possible pseudo states a link can have in CSS:

a:link {color:#FF0000;}    /* unvisited link, same as regular 'a' */
a:hover {color:#FF00FF;}   /* mouse over link */
a:focus {color:#0000FF;}   /* link has focus */
a:active {color:#0000FF;}  /* selected link */
a:visited {color:#00FF00;} /* visited link */

It seems your makefile didn't include the appropriate .so file. You can correct this problem with the steps below:

1. Install sqlite-devel (or libsqlite3-dev on some Debian-based systems)
2. Re-configure and re-compiled Python with ./configure --enable-loadable-sqlite-extensions && make && sudo make install

Note

The sudo make install part will set that python version to be the system-wide standard, which can have unforseen consequences. If you run this command on your workstation, you'll probably want to have it installed alongside the existing python, which can be done with sudo make altinstall.

Most databases have a native UUID type these days to make working with them easier. If yours doesn't, they're just 128-bit numbers, so you can use BINARY(16), and if you need the text format frequently, e.g. for troubleshooting, then add a calculated column to generate it automatically from the binary column. There is no good reason to store the (much larger) text form.

The only way that worked for me was:

navigationController?.navigationBar.backItem?.title = ""

UPDATE:

When I changed the segue animation flag to true (It was false before), the only way that worked for me was:

navigationController?.navigationBar.topItem?.title = ""

Addition to Mark Byers answer :

Sometimes you also want to insert Hardcoded details else there may be Unique constraint fail etc. So use following in such situation where you override some values of the columns.

INSERT INTO matrimony_domain_details (domain, type, logo_path)
SELECT 'www.example.com', type, logo_path
FROM matrimony_domain_details
WHERE id = 367

Here domain value is added by me me in Hardcoded way to get rid from Unique constraint.

I had the same issue with the MVC template not appearing in VS2015.

I checked Web Developer Tools when originally installing. It was still checked when trying to Modify the install. I tried unchecking and updating the install but next time I went back to Modify, it was still checked. And still no MVC template.

I got it working by uninstalling: Microsoft ASP.NET Web Frameworks and Tools 2015 via the Programs and Features windows and re-installing. Here's the link for those who don't have it.

Don't do things like [A-Z] or [0-9]. Do \p{Lu} and \d instead. Of course, this is valid for perl based regex flavours. This includes java.

I would suggest that you don't make some huge regex. First split the text in sentences. then tokenize it (split into words). Use a regex to check each token/word. Skip the first token from sentence. Check if all tokens are uppercase beforehand and skip the whole sentence if so, or alter the regex in this case.

import pickle

dictobj = {'Jack' : 123, 'John' : 456}

filename = "/foldername/filestore"

fileobj = open(filename, 'wb')

pickle.dump(dictobj, fileobj)

fileobj.close()

This is the solution I found:

usedID = []

x = [
{'id':1,'name':'john', 'age':34},
{'id':1,'name':'john', 'age':34},
{'id':2,'name':'hanna', 'age':30},
]

for each in x:
    if each['id'] in usedID:
        x.remove(each)
    else:
        usedID.append(each['id'])

print x

Basically you check if the ID is present in the list, if it is, delete the dictionary, if not, append the ID to the list

There shouldn't be any LINQ magic keeping you from doing this. Don't use projection though that'll return an anonymous type.

User u = UserCollection.FirstOrDefault(u => u.Id == 1);
u.FirstName = "Bob"

That will modify the real object, as well as:

foreach (User u in UserCollection.Where(u => u.Id > 10)
{
    u.Property = SomeValue;
}

Just to complement the other answers as I don't think anyone mentioned this here: notifyDataSetChanged() should be executed on the main thread (other notify<Something> methods of RecyclerView.Adapter as well, of course)

From what I gather, since you have the parsing procedures and the call to notifyDataSetChanged() in the same block, either you're calling it from a worker thread, or you're doing JSON parsing on main thread (which is also a no-no as I'm sure you know). So the proper way would be:

protected void parseResponse(JSONArray response, String url) {
    // insert dummy data for demo
    // <yadda yadda yadda>
    mBusinessAdapter = new BusinessAdapter(mBusinesses);
    // or just use recyclerView.post() or [Fragment]getView().post()
    // instead, but make sure views haven't been destroyed while you were
    // parsing
    new Handler(Looper.getMainLooper()).post(new Runnable() {
        public void run() {
            mBusinessAdapter.notifyDataSetChanged();
        }
    });

}

PS Weird thing is, I don't think you get any indications about the main thread thing from either IDE or run-time logs. This is just from my personal observations: if I do call notifyDataSetChanged() from a worker thread, I don't get the obligatory Only the original thread that created a view hierarchy can touch its views message or anything like that - it just fails silently (and in my case one off-main-thread call can even prevent succeeding main-thread calls from functioning properly, probably because of some kind of race condition)

Moreover, neither the RecyclerView.Adapter api reference nor the relevant official dev guide explicitly mention the main thread requirement at the moment (the moment is 2017) and none of the Android Studio lint inspection rules seem to concern this issue either.

But, here is an explanation of this by the author himself

    self.navigationItem.rightBarButtonItem =[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refreshData)];



}

-(void)refreshData{
    progressHud= [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
    [progressHud setLabelText:@"?????..."];
    [self loadNetwork];
}

and if data in "age" column has similar records (i.e. many people are 25 years old, many others are 32 and so on), it causes confusion in aligning right count to each student. in order to avoid it, I joined the tables on student ID as well.

SELECT S.id, S.age, C.cnt
FROM Students S 
INNER JOIN (SELECT id, age, count(age) as cnt  FROM Students GROUP BY student,age) 
C ON S.age = C.age *AND S.id = C.id*

I think it depends on how you installed python. Note that you can have multiple installs of python, I do on my machine. However, if you install via an msi of a version of python 2.2 or above, I believe it creates a registry key like so:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Python.exe

which gives this value on my machine:

C:\Python25\Python.exe

You just read the registry key to get the location.

However, you can install python via an xcopy like model that you can have in an arbitrary place, and you just have to know where it is installed.

%matplotlib inline

For me working with notebook, adding the above line before the plot works.

Or, if you want to see output in the Output window of Visual Studio, System.Diagnostics.Debug.WriteLine(stuff)

It is amusing to return 418 I'm a teapot to requests that are obviously crafted or malicious and "can't happen", such as failing CSRF check or missing request properties.

2.3.2 418 I'm a teapot

Any attempt to brew coffee with a teapot should result in the error code "418 I'm a teapot". The resulting entity body MAY be short and stout.

To keep it reasonably serious, I restrict usage of funny error codes to RESTful endpoints that are not directly exposed to the user.

To learn what row was selected, add a ListSelectionListener, as shown in How to Use Tables in the example SimpleTableSelectionDemo. A JList can be constructed directly from the linked list's toArray() method, and you can add a suitable listener to it for details.

There is no i in xpath is not entirely true. You can still use the count() to find the index.

The page has 2 tables and has 6 columns each with unique column names and 6 rows with variable data. The last row has the Modify button in both the tables.

Assuming that the user has to select the 4th Modify button from the first table based on the heading

Use the xpath //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]/button

The count() operator comes in handy in situations like these.

Logic:

1. Find the header for the Modify button using //th[.='Heading 4']
2. Find the index of the header column using count(//tr/th[.='Heading 4']/preceding-sibling::th)+1

Note: Index starts at 0

3. Get the rows for the corresponding header using //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]

4. Get the Modify button from the extracted node list using //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]/button

I'm assuming each entry in "ips" can have multiple name value pairs - so it's nested. You can achieve this data structure as such:

var ips = {}

function addIpId(ipID, name, value) {
    if (!ips[ipID]) ip[ipID] = {};
    var entries = ip[ipID];
    // you could add a check to ensure the name-value par's not already defined here
    var entries[name] = value;
}

This works for me:

Click on Start and type in CMD
Right click and click on Run as administrator
Then from C:\windows\system32 type 
lodctr /R:PerfStringBackup.INI 

and press Enter
then restart the compurter and retry!

In my case, it happens with ADT 22.

After I remove the "appcompat_v7" as library project. I works.

My solution to do this:

li span.show::after{
  content: url("/sites/default/files/new5.gif");
  padding-left: 5px;
}

When a process uses fork(), it creates a duplicate copy of itself and this duplicates becomes the child of the process. The fork() is implemented using clone() system call in linux which returns twice from kernel.

• A non-zero value(Process ID of child) is returned to the parent.
• A value of zero is returned to the child.
• In case the child is not created successfully due to any issues like low memory, -1 is returned to the fork().

Let’s understand this with an example:

pid = fork(); 
// Both child and parent will now start execution from here.
if(pid < 0) {
    //child was not created successfully
    return 1;
}
else if(pid == 0) {
    // This is the child process
    // Child process code goes here
}
else {
    // Parent process code goes here
}
printf("This is code common to parent and child");

In the example, we have assumed that exec() is not used inside the child process.

But a parent and child differs in some of the PCB(process control block) attributes. These are:

1. PID - Both child and parent have a different Process ID.
2. Pending Signals - The child doesn’t inherit Parent’s pending signals. It will be empty for the child process when created.
3. Memory Locks - The child doesn’t inherit its parent’s memory locks. Memory locks are locks which can be used to lock a memory area and then this memory area cannot be swapped to disk.
4. Record Locks - The child doesn’t inherit its parent’s record locks. Record locks are associated with a file block or an entire file.
5. Process resource utilisation and CPU time consumed is set to zero for the child.
6. The child also doesn’t inherit timers from the parent.

But what about the child memory? Is a new address space created for a child?

The answers in no. After the fork(), both parent and child share the memory address space of parent. In linux, these address space are divided into multiple pages. Only when the child writes to one of the parent memory pages, a duplicate of that page is created for the child. This is also known as copy on write(Copy parent pages only when the child writes to it).

Let’s understand copy on write with an example.

int x = 2;
pid = fork();
if(pid == 0) {
    x = 10;
    // child is changing the value of x or writing to a page
    // One of the parent stack page will contain this local               variable. That page will be duplicated for child and it will store the value 10 in x in duplicated page.  
}
else {
    x = 4;
}

But why is copy on write necessary?

A typical process creation takes place through fork()-exec() combination. Let’s first understand what exec() does.

Exec() group of functions replaces the child’s address space with a new program. Once exec() is called within a child, a separate address space will be created for the child which is totally different from the parent’s one.

If there was no copy on write mechanism associated with fork(), duplicate pages would have created for the child and all the data would have been copied to child’s pages. Allocating new memory and copying data is a very expensive process(takes processor’s time and other system resources). We also know that in most cases, the child is going to call exec() and that would replace the child’s memory with a new program. So the first copy which we did would have been a waste if copy on write was not there.

pid = fork();
if(pid == 0) {
    execlp("/bin/ls","ls",NULL);
    printf("will this line be printed"); // Think about it
    // A new memory space will be created for the child and that   memory will contain the "/bin/ls" program(text section), it's stack, data section and heap section
else {
    wait(NULL);
    // parent is waiting for the child. Once child terminates, parent will get its exit status and can then continue
}
return 1; // Both child and parent will exit with status code 1.

Why does parent waits for a child process?

1. The parent can assign a task to it’s child and wait till it completes it’s task. Then it can carry some other work.
2. Once the child terminates, all the resources associated with child are freed except for the process control block. Now, the child is in zombie state. Using wait(), parent can inquire about the status of child and then ask the kernel to free the PCB. In case parent doesn’t uses wait, the child will remain in the zombie state.

Why is exec() system call necessary?

It’s not necessary to use exec() with fork(). If the code that the child will execute is within the program associated with parent, exec() is not needed.

But think of cases when the child has to run multiple programs. Let’s take the example of shell program. It supports multiple commands like find, mv, cp, date etc. Will be it right to include program code associated with these commands in one program or have child load these programs into the memory when required?

It all depends on your use case. You have a web server which given an input x that returns the 2^x to the clients. For each request, the web server creates a new child and asks it to compute. Will you write a separate program to calculate this and use exec()? Or you will just write computation code inside the parent program?

Usually, a process creation involves a combination of fork(), exec(), wait() and exit() calls.

This was a strange problem since my hosts IIS shouldn't complain that it requires integrated pipeline mode when it already is in that mode as I stated in my question as:

I have searched a lot and unable to find anything except for directing the reader to change the pipeline from classic mode to integrated mode that which I already did with no luck..

Using Levi's directions, I put <%: System.Web.Hosting.HttpRuntime.UsingIntegratedPipeline %> and <%: System.Web.Hosting.HttpRuntime.IISVersion %>* on an empty aspx page and told my host what going on and asked them to fix the problem and confirm the problem using the page I uploaded... I checked very often if something has changed at the state of the page and I can see that they struggled 3-4 hours to solve it...

When I asked what they have done to solve the problem, their answer was kind of 'classified', since they said:

Our team made the required changes on the server

The problem was all with my host.

* Update: As Ben stated in the comments

1. <%: System.Web.Hosting.HttpRuntime.UsingIntegratedPipeline %> and
2. <%: System.Web.Hosting.HttpRuntime.IISVersion %>

are no longer valid and they are now:

1. <%: System.Web.HttpRuntime.UsingIntegratedPipeline %> and
2. <%: System.Web.HttpRuntime.IISVersion %>

The easiest way I can think of is the following:

<?php

$selection = array('PHP', 'ASP');
echo '<select>
      <option value="0">Please Select Option</option>';

foreach ($selection as $selection) {
    $selected = ($options == $selection) ? "selected" : "";
    echo '<option '.$selected.' value="'.$selection.'">'.$selection.'</option>';
}

echo '</select>';

The code basically places all of your options in an array which are called upon in the foreach loop. The loop checks to see if your $options variable matches the current selection it's on, if it's a match then $selected will = selected, if not then it is set as blank. Finally the option tag is returned containing the selection from the array and if that particular selection is equal to your $options variable, it's set as the selected option.

This is easy all you need to do is something like this Grab your contents like this

  $result->get(filed1) = 'some modification';
  $result->get(filed2) = 'some modification2';

'use strict'
var fs = require("fs");

/***
 * implementation of readFileSync
 */
var data = fs.readFileSync('input.txt');
console.log(data.toString());
console.log("Program Ended");

/***
 * implementation of readFile 
 */
fs.readFile('input.txt', function (err, data) {
    if (err) return console.error(err);
   console.log(data.toString());
});

console.log("Program Ended");

For better understanding run the above code and compare the results..

There are many ways to exit after insert

When you insert data into a table, you can use the OUTPUT clause to return a copy of the data that’s been inserted into the table. The OUTPUT clause takes two basic forms: OUTPUT and OUTPUT INTO. Use the OUTPUT form if you want to return the data to the calling application. Use the OUTPUT INTO form if you want to return the data to a table or a table variable.

DECLARE @MyTableVar TABLE (id INT,NAME NVARCHAR(50));

INSERT INTO tableName
(
  NAME,....
)OUTPUT INSERTED.id,INSERTED.Name INTO @MyTableVar
VALUES
(
   'test',...
)

IDENT_CURRENT: It returns the last identity created for a particular table or view in any session.

SELECT IDENT_CURRENT('tableName') AS [IDENT_CURRENT]

SCOPE_IDENTITY: It returns the last identity from a same session and the same scope. A scope is a stored procedure/trigger etc.

SELECT SCOPE_IDENTITY() AS [SCOPE_IDENTITY];  

@@IDENTITY: It returns the last identity from the same session.

SELECT @@IDENTITY AS [@@IDENTITY];

To do this for multiple dataframes, you can do a for loop over them:

fig = plt.figure(num=None, figsize=(10, 8))
ax = dict_of_dfs['FOO'].column.plot()
for BAR in dict_of_dfs.keys():
    if BAR == 'FOO':
        pass
    else:
        dict_of_dfs[BAR].column.plot(ax=ax)

Try setting the charset on your Content-Type:

1. No, there isn't anything that should be avoided
2. The parameters related to performance are not in web.xml they are in the servlet container configuration files (server.xml on tomcat)

3. No. But the default servlet (mapped in a web.xml at a common location in your servlet container) should preferably disable file listings (so that users don't see the contents of your web folders):

   listings true

For 'd/m/Y' dates:

usort($array, function ($a, $b, $i = 'datetime') { 
    $t1 = strtotime(str_replace('/', '-', $a[$i]));
    $t2 = strtotime(str_replace('/', '-', $b[$i]));

    return $t1 > $t2;
});

where $i is the array index

Try this:

System.Windows.Forms.MessageBox.Show("Here's a message!");

This function works to arrays and objects. obs: it works like array_column php function. It means that an optional third parameter can be passed to define what column will correspond to the indices of return.

function array_column(list, column, indice){
    var result;

    if(typeof indice != "undefined"){
        result = {};

        for(key in list)
            result[list[key][indice]] = list[key][column];
    }else{
        result = [];

        for(key in list)
            result.push( list[key][column] );
    }

    return result;
}

This is a conditional version:

function array_column_conditional(list, column, indice){
    var result;

    if(typeof indice != "undefined"){
        result = {};

        for(key in list)
            if(typeof list[key][column] !== 'undefined' && typeof list[key][indice] !== 'undefined')
                result[list[key][indice]] = list[key][column];
    }else{
        result = [];

        for(key in list)
            if(typeof list[key][column] !== 'undefined')
                result.push( list[key][column] );
    }

    return result;
}

usability:

var lista = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

var obj_list = [
  {a: 1, b: 2, c: 3},
  {a: 4, b: 5, c: 6},
  {a: 8, c: 9}
];

var objeto = {
  d: {a: 1, b: 3},
  e: {a: 4, b: 5, c: 6},
  f: {a: 7, b: 8, c: 9}
};

var list_obj = {
  d: [1, 2, 3],
  e: [4, 5],
  f: [7, 8, 9]
};

console.log( "column list: ", array_column(lista, 1) );
console.log( "column obj_list: ", array_column(obj_list, 'b', 'c') );
console.log( "column objeto: ", array_column(objeto, 'c') );
console.log( "column list_obj: ", array_column(list_obj, 0, 0) );

console.log( "column list conditional: ", array_column_conditional(lista, 1) );
console.log( "column obj_list conditional: ", array_column_conditional(obj_list, 'b', 'c') );
console.log( "column objeto conditional: ", array_column_conditional(objeto, 'c') );
console.log( "column list_obj conditional: ", array_column_conditional(list_obj, 0, 0) );

Output:

/*
column list:  Array [ 2, 5, 8 ]
column obj_list:  Object { 3: 2, 6: 5, 9: undefined }
column objeto:  Array [ undefined, 6, 9 ]
column list_obj:  Object { 1: 1, 4: 4, 7: 7 }

column list conditional:  Array [ 2, 5, 8 ]
column obj_list conditional:  Object { 3: 2, 6: 5 }
column objeto conditional:  Array [ 6, 9 ]
column list_obj conditional:  Object { 1: 1, 4: 4, 7: 7 }

What you are looking for can be found here. It may exist a more elegant way to accomplish that, but one possible approach is

Option 1 (preferred):

final Duration timeout = Duration.ofSeconds(30);
ExecutorService executor = Executors.newSingleThreadExecutor();

final Future<String> handler = executor.submit(new Callable() {
    @Override
    public String call() throws Exception {
        return requestDataFromModem();
    }
});

try {
    handler.get(timeout.toMillis(), TimeUnit.MILLISECONDS);
} catch (TimeoutException e) {
    handler.cancel(true);
}

executor.shutdownNow();

Option 2:

final Duration timeout = Duration.ofSeconds(30);
ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);

final Future<String> handler = executor.submit(new Callable() {
    @Override
    public String call() throws Exception {
        return requestDataFromModem();
    }
});

executor.schedule(new Runnable() {
    @Override
    public void run(){
        handler.cancel(true);
    }      
}, timeout.toMillis(), TimeUnit.MILLISECONDS);

executor.shutdownNow();

Those are only a draft so that you can get the main idea.

To give margin to any control you could wrap the control with border like this

    <Border Padding="10">
            <AnyControl>

curl -s http://google.com > temp.html

works for curl version 7.19.5 on Ubuntu 9.10 (no progress bar). But if for some reason that does not work on your platform, you could always redirect stderr to /dev/null:

curl  http://google.com 2>/dev/null > temp.html

The easiest way to do achieve this is :

Add the following theme to your styles.xml

<style name="DialogTheme" parent="AppTheme">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">false</item>
    <item name="android:windowIsFloating">false</item>
</style>

and in your class extending DialogFragment, override

@Override
public int getTheme() {
    return R.style.DialogTheme;
}

This will work on Android OS 11(R) as well.

Don't know exactly what kind of dataset you have, so I provide general answer.

x <- c(1,2,NA,3,4,5)
y <- c(1,2,3,NA,6,8)
my.data <- data.frame(x, y)
> my.data
   x  y
1  1  1
2  2  2
3 NA  3
4  3 NA
5  4  6
6  5  8
# Exclude rows with NA values
my.data[complete.cases(my.data),]
  x y
1 1 1
2 2 2
5 4 6
6 5 8

But be VERY careful about letting a user select the file. You don't really want to allow them to get a file called, for example,

../../../../../../../../../../etc/passwd

or other sensitive system files.

(Sorry, it's been a while since I was a linux sysadmin, and I think this is a sensitive file, from what I remember)

You should be able to perform a select on the orders table, using a raw WHERE to find the max(id) in a subquery, like this:

 \DB::table('orders')->where('id', \DB::raw("(select max(`id`) from orders)"))->get();

If you want to use Eloquent (for example, so you can convert your response to an object) you will want to use whereRaw, because some functions such as toJSON or toArray will not work without using Eloquent models.

 $order = Order::whereRaw('id = (select max(`id`) from orders)')->get();

That, of course, requires that you have a model that extends Eloquent.

 class Order extends Eloquent {}

As mentioned in the comments, you don't need to use whereRaw, you can do the entire query using the query builder without raw SQL.

 // Using the Query Builder
 \DB::table('orders')->find(\DB::table('orders')->max('id'));

 // Using Eloquent
 $order = Order::find(\DB::table('orders')->max('id'));

(Note that if the id field is not unique, you will only get one row back - this is because find() will only return the first result from the SQL server.).

Use the in keyword without is.

if "x" in dog:
    print "Yes!"

If you'd like to check for the non-existence of a character, use not in:

if "x" not in dog:
    print "No!"

I don't know if it's a trick. But when I was a junior in university a friend of mine and I were completing a lab in our intro C++ course. We had to take a person's name and capitalize it, display it back, and then give them the option of displaying their name "last, first". For this lab we were prohibited from using array notation.

He showed me this code, I thought it was the coolest thing I'd seen at the time.

char * ptr = "first name";

//flies to the end of the array, regardless of length
while( *ptr++ );

Personally I'd go with AJAX.

If you cannot switch to @Ajax... helpers, I suggest you to add a couple of properties in your model

public bool TriggerOnLoad { get; set; }
public string TriggerOnLoadMessage { get; set: }

Change your view to a strongly typed Model via

@using MyModel

Before returning the View, in case of successfull creation do something like

MyModel model = new MyModel();
model.TriggerOnLoad = true;
model.TriggerOnLoadMessage = "Object successfully created!";
return View ("Add", model);

then in your view, add this

@{
   if (model.TriggerOnLoad) {
   <text>
   <script type="text/javascript">
     alert('@Model.TriggerOnLoadMessage');
   </script>
   </text>
   }
}

Of course inside the tag you can choose to do anything you want, event declare a jQuery ready function:

$(document).ready(function () {
   alert('@Model.TriggerOnLoadMessage');
});

Please remember to reset the Model properties upon successfully alert emission.

Another nice thing about MVC is that you can actually define an EditorTemplate for all this, and then use it in your view via:

@Html.EditorFor (m => m.TriggerOnLoadMessage)

But in case you want to build up such a thing, maybe it's better to define your own C# class:

class ClientMessageNotification {
    public bool TriggerOnLoad { get; set; }
    public string TriggerOnLoadMessage { get; set: }
}

and add a ClientMessageNotification property in your model. Then write EditorTemplate / DisplayTemplate for the ClientMessageNotification class and you're done. Nice, clean, and reusable.
