In my case, I was trying to connect from the Ubuntu app in Windows 10 and got the error above. It could be resolved without any permission changes by running sudo su in the Ubuntu console prior to the actual command

This worked for me in IDLE Python 3.8.2

print('''"A word with quotation marks"''')

Triple single quotes seem to allow you to include your double quotes as part of the string.

You've got two ways to go forward:

JSONP

If this API supports JSONP, the easiest way to fix this issue is to add &callback to the end of the URL. You can also try &callback=. If that doesn't work, it means the API does not support JSONP, so you must try the other solution.

Proxy Script

You can create a proxy script on the same domain as your website in order to avoid the cross-origin issues. This will only work with HTTP URLs, not HTTPS URLs, but it shouldn't be too difficult to modify if you need that.

<?php
// File Name: proxy.php
if (!isset($_GET['url'])) {
    die(); // Don't do anything if we don't have a URL to work with
}
$url = urldecode($_GET['url']);
$url = 'http://' . str_replace('http://', '', $url); // Avoid accessing the file system
echo file_get_contents($url); // You should probably use cURL. The concept is the same though

Then you just call this script with jQuery. Be sure to urlencode the URL.

$.ajax({
    url      : 'proxy.php?url=http%3A%2F%2Fapi.master18.tiket.com%2Fsearch%2Fautocomplete%2Fhotel%3Fq%3Dmah%26token%3D90d2fad44172390b11527557e6250e50%26secretkey%3D83e2f0484edbd2ad6fc9888c1e30ea44%26output%3Djson',
    type     : 'GET',
    dataType : 'json'
}).done(function(data) {
    console.log(data.results.result[1].category); // Do whatever you want here
});

The Why

You're getting this error because of XMLHttpRequest same origin policy, which basically boils down to a restriction of ajax requests to URLs with a different port, domain or protocol. This restriction is in place to prevent cross-site scripting (XSS) attacks.

More Information

Our solutions by pass these problems in different ways.

JSONP uses the ability to point script tags at JSON (wrapped in a javascript function) in order to receive the JSON. The JSONP page is interpreted as javascript, and executed. The JSON is passed to your specified function.

The proxy script works by tricking the browser, as you're actually requesting a page on the same origin as your page. The actual cross-origin requests happen server-side.

just do that

s = s.Replace("\n", String.Empty).Replace("\t", String.Empty).Replace("\r", String.Empty);

import os    
os.path.getsize(fullpathhere) > 0

I had encountered this same need, and I used a combination of Linq's Skip() and Take() methods. I multiply the number I take by the number of iterations this far, and that gives me the number of items to skip, then I take the next group.

        var categories = Properties.Settings.Default.MovementStatsCategories;
        var items = summariesWithinYear
            .Select(s =>  s.sku).Distinct().ToList();

        //need to run by chunks of 10,000
        var count = items.Count;
        var counter = 0;
        var numToTake = 10000;

        while (count > 0)
        {
            var itemsChunk = items.Skip(numToTake * counter).Take(numToTake).ToList();
            counter += 1;

            MovementHistoryUtilities.RecordMovementHistoryStatsBulk(itemsChunk, categories, nLogger);

            count -= numToTake;
        }

You can use input text with "list" attribute, which refers to the datalist of values.

<input type="text" name="city" list="cityname">_x000D_
    <datalist id="cityname">_x000D_
      <option value="Boston">_x000D_
      <option value="Cambridge">_x000D_
    </datalist>

This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist

simply use the Out-File cmd but DON'T forget to give an encoding type: -Encoding UTF8

so use it so:

$log | Out-File -Append C:\as\whatever.csv -Encoding UTF8

-Append is required if you want to write in the file more then once.

• Case classes define a compagnon object with apply and unapply methods
• Case classes extends Serializable
• Case classes define equals hashCode and copy methods
• All attributes of the constructor are val (syntactic sugar)

Another way of dealing with this situation if your files ARE already checked in, and your files have been merged (but not committed, so the merge conflicts are inserted into the file) is to run:

git reset

This will switch to HEAD, and tell git to forget any merge conflicts, and leave the working directory as is. Then you can edit the files in question (search for the "Updated upstream" notices). Once you've dealt with the conflicts, you can run

git add -p

which will allow you to interactively select which changes you want to add to the index. Once the index looks good (git diff --cached), you can commit, and then

git reset --hard

to destroy all the unwanted changes in your working directory.

In views with {{}} and/or ng-model, Angular is setting up $watch()es for you behind the scenes.

By default $watch compares by reference. If you set the third parameter to $watch to true, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:

$scope.$watch('myModel', function() { ... }, true);

Update: Angular v1.2 added a new method for this, `$watchCollection():

$scope.$watchCollection('myModel', function() { ... });

Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

Same thing, Just start the table name with # or ##:

CREATE TABLE #TemporaryTable          -- Local temporary table - starts with single #
(
    Col1 int,
    Col2 varchar(10)
    ....
);

CREATE TABLE ##GlobalTemporaryTable   -- Global temporary table - note it starts with ##.
(
    Col1 int,
    Col2 varchar(10)
    ....
);

Temporary table names start with # or ## - The first is a local temporary table and the last is a global temporary table.

Here is one of many articles describing the differences between them.

You basically have two choices:

1.Require an instance:

public Navigation(T t) {     this("", "", t); } 

2.Require a class instance:

public Navigation(Class<T> c) {     this("", "", c.newInstance()); } 

You could use a factory pattern, but ultimately you'll face this same issue, but just push it elsewhere in the code.

Try this:

$("#test-element").on("click" ,function() {
    alert("click");
});

The document way of doing it is weird too. That would make sense to me if used for a class selector, but in the case of an id you probably just have useless DOM traversing there. In the case of the id selector, you get that element instantly.

Please try below CLI command in current project directory. It will create dist folder bundle. so you can upload all files within dist folder for deployments.

ng build --prod --aot --base-href.

Try the clear property.

Remember that float removes an element from the document layout - so yes, in a way it is "interfering" with br and p tags, in the sense that it would basically be ignoring anything in the main flow layout.

slide to right

viewPager.arrowScroll(View.FOCUS_RIGHT);

slide to left

viewPager.arrowScroll(View.FOCUS_LEFT);

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

$each will work.. Another option is jQuery Ajax Callback for array result

function displayResultForLog(result) {
  if (result.hasOwnProperty("d")) {
    result = result.d
  }

  if (result !== undefined && result != null) {
    if (result.hasOwnProperty('length')) {
      if (result.length >= 1) {
        for (i = 0; i < result.length; i++) {
          var sentDate = result[i];
        }
      } else {
        $(requiredTable).append('Length is 0');
      }
    } else {
      $(requiredTable).append('Length is not available.');
    }

  } else {
    $(requiredTable).append('Result is null.');
  }
}

summation and your other functions are defined after they're used in main, and so the compiler has made a guess about it's signature; in other words, an implicit declaration has been assumed.

You should declare the function before it's used and get rid of the warning. In the C99 specification, this is an error.

Either move the function bodies before main, or include method signatures before main, e.g.:

#include <stdio.h>

int summation(int *, int *, int *);

int main()
{
    // ...

I have upvoted @dnuttle's answer, but ended up using the following strategy:

// On doc ready for modern browsers
document.addEventListener('DOMContentLoaded', (e) => {
  // Scope all logic related to what you want to achieve by using a function
  const waitForMyFunction = () => {
    // Use a timeout id to identify your process and purge it when it's no longer needed
    let timeoutID;
    // Check if your function is defined, in this case by checking its type
    if (typeof myFunction === 'function') {
      // We no longer need to wait, purge the timeout id
      window.clearTimeout(timeoutID);
      // 'myFunction' is defined, invoke it with parameters, if any
      myFunction('param1', 'param2');
    } else {
      // 'myFunction' is undefined, try again in 0.25 secs
      timeoutID = window.setTimeout(waitForMyFunction, 250);
    }
  };
  // Initialize
  waitForMyFunction();
});

It is tested and working! ;)

Take a backup of your htdocs and data folder (subfolder of MySQL folder), reinstall upgraded version and replace those folders.

Note: In case you have changed config files like PHP (php.ini), Apache (httpd.conf) or any other, please take back up of those files as well and replace them with newly installed version.

Probably my question should have been more specific. I actually know a base class for the string so solved it by:

ReportClass report = (ReportClass)Activator.CreateInstance(Type.GetType(reportClass));

The Activator.CreateInstance class has various methods to achieve the same thing in different ways. I could have cast it to an object but the above is of the most use to my situation.

The escape character in batch scripts is ^. But for double-quoted strings, double up the quotes:

"string with an embedded "" character"

Your second example is correct; you don't need to delete the monsters array itself, just the individual objects you created.

Extending on Adam Rosenfield's answer for Windows.

I tested this code with on both VS2013 Update 4 and VS2015 preview:

// test.c

#include <stdio.h>
#include <BaseTsd.h> // see the note below

int main()
{
    size_t x = 1;
    SSIZE_T y = 2;
    printf("%zu\n", x);  // prints as unsigned decimal
    printf("%zx\n", x);  // prints as hex
    printf("%zd\n", y);  // prints as signed decimal
    return 0;
}

VS2015 generated binary outputs:

1
1
2

while the one generated by VS2013 says:

zu
zx
zd

Note: ssize_t is a POSIX extension and SSIZE_T is similar thing in Windows Data Types, hence I added <BaseTsd.h> reference.

Additionally, except for the follow C99/C11 headers, all C99 headers are available in VS2015 preview:

C11 - <stdalign.h>
C11 - <stdatomic.h>
C11 - <stdnoreturn.h>
C99 - <tgmath.h>
C11 - <threads.h>

Also, C11's <uchar.h> is now included in latest preview.

In Netbeans 8.2

1. Dowload the binaries from the web source. The Apache Commos are in: [http://commons.apache.org/components.html][1] In this case, you must select the "Logging" in the Components menu and follow the link to downloads in the Releases part. Direct URL: [http://commons.apache.org/proper/commons-logging/download_logging.cgi][2] For me, the correct download was the file: commons-logging-1.2-bin.zip from the Binaries.

2. Unzip downloaded content. Now, you can see several jar files inside the directory created from the zip file.

3. Add the library to the project. Right click in the project, select Properties and click in Libraries (in the left side). Click the button "Add Jar/Folder". Go to the previously unzipped contents and select the properly jar file. Clic in "Open" and click in"Ok". The library has been loaded!

My code was broken because I was using a deprecated technique. It used to be this:

video.src = window.URL.createObjectURL(localMediaStream);
video.play();

Then I replaced that with this:

video.srcObject = localMediaStream;
video.play();

That worked beautifully.

EDIT: Recently localMediaStream has been deprecated and replaced with MediaStream. The latest code looks like this:

video.srcObject = new MediaStream();

References:

Use set or select

SET @counter := 100;
SELECT @variable_name := value;

example :

SELECT @price := MAX(product.price)
FROM product 

Put the database password in a file, make it read-only to the user serving the files.

Unless you have some means of only allowing the php server process to access the database, this is pretty much all you can do.

For those who want to use JavaMail with Kotlin in 2020:

First: Add these dependencies to your build.gradle file (official JavaMail Maven Dependencies)

implementation 'com.sun.mail:android-mail:1.6.5'

implementation 'com.sun.mail:android-activation:1.6.5'

implementation "org.bouncycastle:bcmail-jdk15on:1.65"

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.7"

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.7"

BouncyCastle is for security reasons.

Second: Add these permissions to your AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Third: When using SMTP, create a Config file

object Config {
    const val EMAIL_FROM = "[email protected]"
    const val PASS_FROM = "Your_Sender_Password"

    const val EMAIL_TO = "[email protected]"
}

Fourth: Create your Mailer Object

object Mailer {

init {
    Security.addProvider(BouncyCastleProvider())
}

private fun props(): Properties = Properties().also {
        // Smtp server
        it["mail.smtp.host"] = "smtp.gmail.com"
        // Change when necessary
        it["mail.smtp.auth"] = "true"
        it["mail.smtp.port"] = "465"
        // Easy and fast way to enable ssl in JavaMail
        it["mail.smtp.ssl.enable"] = true
    }

// Dont ever use "getDefaultInstance" like other examples do!
private fun session(emailFrom: String, emailPass: String): Session = Session.getInstance(props(), object : Authenticator() {
    override fun getPasswordAuthentication(): PasswordAuthentication {
        return PasswordAuthentication(emailFrom, emailPass)
    }
})

private fun builtMessage(firstName: String, surName: String): String {
    return """
            <b>Name:</b> $firstName  <br/>
            <b>Surname:</b> $surName <br/>
        """.trimIndent()
}

private fun builtSubject(issue: String, firstName: String, surName: String):String {
    return """
            $issue | $firstName, $surName
        """.trimIndent()
}

private fun sendMessageTo(emailFrom: String, session: Session, message: String, subject: String) {
    try {
        MimeMessage(session).let { mime ->
            mime.setFrom(InternetAddress(emailFrom))
            // Adding receiver
            mime.addRecipient(Message.RecipientType.TO, InternetAddress(Config.EMAIL_TO))
            // Adding subject
            mime.subject = subject
            // Adding message
            mime.setText(message)
            // Set Content of Message to Html if needed
            mime.setContent(message, "text/html")
            // send mail
            Transport.send(mime)
        }

    } catch (e: MessagingException) {
        Log.e("","") // Or use timber, it really doesn't matter
    }
}

fun sendMail(firstName: String, surName: String) {
        // Open a session
        val session = session(Config.EMAIL_FROM, Config.PASSWORD_FROM)

        // Create a message
        val message = builtMessage(firstName, surName)

        // Create subject
        val subject = builtSubject(firstName, surName)

        // Send Email
        CoroutineScope(Dispatchers.IO).launch { sendMessageTo(Config.EMAIL_FROM, session, message, subject) }
}

Note

• If you want a more secure way to send your email (and you want a more secure way!), use http as mentioned in the solutions before (I will maybe add it later in this answer)
• You have to properly check, if the users phone has internet access, otherwise the app will crash.
• When using gmail, enable "less secure apps" (this will not work, when you gmail has two factors enabled) https://myaccount.google.com/lesssecureapps?pli=1
• Some credits belong to: https://medium.com/@chetan.garg36/android-send-mails-not-intent-642d2a71d2ee (he used RxJava for his solution)

in my case, I just had to do something like this :

date1.toString().equals(date2.toString())

And it worked!

One way of doing this is using Html tags::

txtTitlevalue.setText(Html.fromHtml("Line1"+"<br>"+"Line2" + " <br>"+"Line3"));

\\. is the simple answer. Here is simple code for your help.

while (line != null) {
    //             
    String[] words = line.split("\\.");
    wr = "";
    mean = "";
    if (words.length > 2) {
        wr = words[0] + words[1];
        mean = words[2];

    } else {
        wr = words[0];
        mean = words[1];
    }
}

I'll tell you how it can be done in eclipse. My dev system - Windows 64bit, Eclipse Luna, Perlipse plugin for eclipse, Strawberry pearl installer. I use perl.exe as my interpreter.

Eclipse > create new perl project > right click project > build path > configure build path > libraries tab > add external source folder > go to the folder where all your perl modules are installed > ok > ok. Done !

In Java there is no direct way to get browser and OS related information.

But to get this few third-party tools are available.

Instead of trusting third-party tools, I suggest you to parse the user agent.

String  browserDetails  =   request.getHeader("User-Agent");

By doing this you can separate the browser details and OS related information easily according to your requirement. PFB the snippet for reference.

        String  browserDetails  =   request.getHeader("User-Agent");
        String  userAgent       =   browserDetails;
        String  user            =   userAgent.toLowerCase();

        String os = "";
        String browser = "";

        log.info("User Agent for the request is===>"+browserDetails);
        //=================OS=======================

$date = DateTime::createFromFormat('d/m/Y', "24/04/2012");
echo $date->format('Y-m-d');

Output

2012-04-24

EDIT:

If the date is 5/4/2010 (both D/M/YYYY or DD/MM/YYYY), this below method is used to convert 5/4/2010 to 2010-4-5 (both YYYY-MM-DD or YYYY-M-D) format.

$old_date = explode('/', '5/4/2010'); 
$new_data = $old_date[2].'-'.$old_date[1].'-'.$old_date[0];

OUTPUT:

2010-4-5

Java has a logical AND operator.
Java has a logical OR operator.

Wrong.

Java has

• two logical AND operators: normal AND is & and short-circuit AND is &&, and
• two logical OR operators: normal OR is | and short-circuit OR is ||.

XOR exists only as ^, because short-circuit evaluation is not possible.

I ran into this issue only to discover a disconnect in one of my library objects. For some reason the project was copying the dll from the old path and not from my development path with the changes. Keep an eye on what dll's are being copied when you compile.

Note: This answer is a pure Gradle answer, I use this in IntelliJ on a regular basis but I don't know how the integration is with Android Studio. I am a believer in knowing what is going on for me, so this is how I use Gradle and Android.

TL;DR Full Example - https://github.com/ethankhall/driving-time-tracker/

Disclaimer: This is a project I am/was working on.

Gradle has a defined structure ( that you can change, link at the bottom tells you how ) that is very similar to Maven if you have ever used it.

Project Root
+-- src
|   +-- main (your project)
|   |   +-- java (where your java code goes)
|   |   +-- res  (where your res go)
|   |   +-- assets (where your assets go)
|   |   \-- AndroidManifest.xml
|   \-- instrumentTest (test project)
|       \-- java (where your java code goes)
+-- build.gradle
\-- settings.gradle

If you only have the one project, the settings.gradle file isn't needed. However you want to add more projects, so we need it.

Now let's take a peek at that build.gradle file. You are going to need this in it (to add the android tools)

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.3'
    }
}

Now we need to tell Gradle about some of the Android parts. It's pretty simple. A basic one (that works in most of my cases) looks like the following. I have a comment in this block, it will allow me to specify the version name and code when generating the APK.

build.gradle

apply plugin: "android"
android {
        compileSdkVersion 17
        /*
        defaultConfig {
            versionCode = 1
            versionName = "0.0.0"
        }
        */
    }

Something we are going to want to add, to help out anyone that hasn't seen the light of Gradle yet, a way for them to use the project without installing it.

build.gradle

task wrapper(type: org.gradle.api.tasks.wrapper.Wrapper) {
    gradleVersion = '1.4'
}

So now we have one project to build. Now we are going to add the others. I put them in a directory, maybe call it deps, or subProjects. It doesn't really matter, but you will need to know where you put it. To tell Gradle where the projects are you are going to need to add them to the settings.gradle.

Directory Structure:

Project Root
+-- src (see above)
+-- subProjects (where projects are held)
|   +-- reallyCoolProject1 (your first included project)
|       \-- See project structure for a normal app
|   \-- reallyCoolProject2 (your second included project)
|       \-- See project structure for a normal app
+-- build.gradle
\-- settings.gradle

settings.gradle:

include ':subProjects:reallyCoolProject1'
include ':subProjects:reallyCoolProject2'

The last thing you should make sure of is the subProjects/reallyCoolProject1/build.gradle has apply plugin: "android-library" instead of apply plugin: "android".

Like every Gradle project (and Maven) we now need to tell the root project about it's dependency. This can also include any normal Java dependencies that you want.

build.gradle

dependencies{
    compile 'com.fasterxml.jackson.core:jackson-core:2.1.4'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.1.4'
    compile project(":subProjects:reallyCoolProject1")
    compile project(':subProjects:reallyCoolProject2')
}

I know this seems like a lot of steps, but they are pretty easy once you do it once or twice. This way will also allow you to build on a CI server assuming you have the Android SDK installed there.

NDK Side Note: If you are going to use the NDK you are going to need something like below. Example build.gradle file can be found here: https://gist.github.com/khernyo/4226923

build.gradle

task copyNativeLibs(type: Copy) {
    from fileTree(dir: 'libs', include: '**/*.so' )  into  'build/native-libs'
}
tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
  pkgTask.jniDir new File('build/native-libs')
}

As the others said, most of the time you won't want to do that because it doesn't copy the assembly to your project and it won't deploy with your project. However, if you're like me, and trying to add a reference that all target machines have in their GAC but it's not a .NET Framework assembly:

1. Open the windows Run dialog (Windows Key + r)
2. Type C:\Windows\assembly\gac_msil. This is some sort of weird hack that lets you browse your GAC. You can only get to it through the run dialog. Hopefully my spreading this info doesn't eventually cause Microsoft to patch it and block it. (Too paranoid? :P)
3. Find your assembly and copy its path from the address bar.
4. Open the Add Reference dialog in Visual Studio and choose the Browse tab.
5. Paste in the path to your GAC assembly.

I don't know if there's an easier way, but I haven't found it. I also frequently use step 1-3 to place .pdb files with their GAC assemblies to make sure they're not lost when I later need to use Remote Debugger.

If you search the first char of string in Sql string

SELECT CHARINDEX('char', 'my char')

=> return 4

From Database.
Blob blob = resultSet.getBlob("pictureBlob");               
byte [] data = blob.getBytes( 1, ( int ) blob.length() );
BufferedImage img = null;
try {
img = ImageIO.read(new ByteArrayInputStream(data));
} catch (IOException e) {
    e.printStackTrace();
}
drawPicture(img);  //  void drawPicture(Image img);

I rewrote David's answer using the with statement, it allows you do do this:

with timeout(seconds=3):
    time.sleep(4)

Which will raise a TimeoutError.

The code is still using signal and thus UNIX only:

import signal

class timeout:
    def __init__(self, seconds=1, error_message='Timeout'):
        self.seconds = seconds
        self.error_message = error_message
    def handle_timeout(self, signum, frame):
        raise TimeoutError(self.error_message)
    def __enter__(self):
        signal.signal(signal.SIGALRM, self.handle_timeout)
        signal.alarm(self.seconds)
    def __exit__(self, type, value, traceback):
        signal.alarm(0)

Running the following helped resolve the issue:

npm config set strict-ssl false

I cannot comment on whether it will cause any other issues at this point in time.

For someone looking for a NEST JS TYPESCRIPT version of the above:

        var scopeBucket: string = bucket ? bucket : this.defaultBucket;
        var params: any = {

fedorqui has a working solution but there is another way to do the same thing.

Chock if a variable is set

#!/bin/bash
amIEmpty='Hello'
# This will be true if the variable has a value
if [ $amIEmpty ]; then
    echo 'No, I am not!';
fi

Or to verify that a variable is empty

#!/bin/bash      
amIEmpty=''
# This will be true if the variable is empty
if [ ! $amIEmpty ]; then
    echo 'Yes I am!';
fi

tldp.org has good documentation about if in bash:
http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html

This error is caused by PDO not being available to PHP.

If you are getting the error on the command line, or not via the same interface your website uses for PHP, you are potentially invoking a different version of PHP, or utlising a different php.ini configuration file when checking phpinfo().

Ensure PDO is loaded, and the PDO drivers for your database are also loaded.

You need the secret string which was used to generate encrypt token. This code works for me:

protected string GetName(string token)
    {
        string secret = "this is a string used for encrypt and decrypt token"; 
        var key = Encoding.ASCII.GetBytes(secret);
        var handler = new JwtSecurityTokenHandler();
        var validations = new TokenValidationParameters
        {
            ValidateIssuerSigningKey = true,
            IssuerSigningKey = new SymmetricSecurityKey(key),
            ValidateIssuer = false,
            ValidateAudience = false
        };
        var claims = handler.ValidateToken(token, validations, out var tokenSecure);
        return claims.Identity.Name;
    }

 def hi():
     bye = 5
     return bye  

print hi()

I created a working demo of a landscape/portrait layout but the zoom must be disabled for it to work without JavaScript:

http://matthewjamestaylor.com/blog/ipad-layout-with-landscape-portrait-modes

Based on Farhan Sahibole's answer:

        header('Content-Disposition: attachment; filename=Image.png');
        header('Content-Type: application/octet-stream'); // Downloading on Android might fail without this
        ob_clean();

        readfile($file);

This is all I needed for this to work. I stripped off anything that isn't required for this to work.

Key is to use ob_clean();

Use dictionary views:

if x in d.viewvalues():
    dosomething()..

There should be only one localhost defined, check sites-enabled or nginx.conf.

var temp = data.oldKey; // or data['oldKey']
data.newKey = temp;
delete data.oldKey;

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Another Python PCA using numpy. The same idea as @doug but that one didn't run.

from numpy import array, dot, mean, std, empty, argsort
from numpy.linalg import eigh, solve
from numpy.random import randn
from matplotlib.pyplot import subplots, show

def cov(X):
    """
    Covariance matrix
    note: specifically for mean-centered data
    note: numpy's `cov` uses N-1 as normalization
    """
    return dot(X.T, X) / X.shape[0]
    # N = data.shape[1]
    # C = empty((N, N))
    # for j in range(N):
    #   C[j, j] = mean(data[:, j] * data[:, j])
    #   for k in range(j + 1, N):
    #       C[j, k] = C[k, j] = mean(data[:, j] * data[:, k])
    # return C

def pca(data, pc_count = None):
    """
    Principal component analysis using eigenvalues
    note: this mean-centers and auto-scales the data (in-place)
    """
    data -= mean(data, 0)
    data /= std(data, 0)
    C = cov(data)
    E, V = eigh(C)
    key = argsort(E)[::-1][:pc_count]
    E, V = E[key], V[:, key]
    U = dot(data, V)  # used to be dot(V.T, data.T).T
    return U, E, V

""" test data """
data = array([randn(8) for k in range(150)])
data[:50, 2:4] += 5
data[50:, 2:5] += 5

""" visualize """
trans = pca(data, 3)[0]
fig, (ax1, ax2) = subplots(1, 2)
ax1.scatter(data[:50, 0], data[:50, 1], c = 'r')
ax1.scatter(data[50:, 0], data[50:, 1], c = 'b')
ax2.scatter(trans[:50, 0], trans[:50, 1], c = 'r')
ax2.scatter(trans[50:, 0], trans[50:, 1], c = 'b')
show()

Which yields the same thing as the much shorter

from sklearn.decomposition import PCA

def pca2(data, pc_count = None):
    return PCA(n_components = 4).fit_transform(data)

As I understand it, using eigenvalues (first way) is better for high-dimensional data and fewer samples, whereas using Singular value decomposition is better if you have more samples than dimensions.

Open cmd type adb shell then press enter. Type ls to view files list.

You have to differenciate between file size and disk usage. The main difference between the two comes from the fact that files are "cut into pieces" and stored in blocks.

Modern block size is 4KiB, so files will use disk space multiple of 4KiB, regardless of how small they are.

If you use the command stat you can see both figures side by side.

stat file.c

If you want a more compact view for a directory, you can use ls -ls, which will give you usage in 1KiB units.

ls -ls dir

Also du will give you real disk usage, in 1KiB units, or dutree with the -u flag.

Example: usage of a 1 byte file

$ echo "" > file.c

$ ls -l file.c
-rw-r--r-- 1 nacho nacho 1 Apr 30 20:42 file.c

$ ls -ls file.c
4 -rw-r--r-- 1 nacho nacho 1 Apr 30 20:42 file.c

$ du file.c
4 file.c

$ dutree file.c
[ file.c 1 B ]

$ dutree -u file.c
[ file.c 4.00 KiB ]

$ stat file.c
 File: file.c

In addition, in modern filesystems we can have snapshots, sparse files (files with holes in them) that further complicate the situation.

You can see more details in this article: understanding file size in Linux

A linebreak in regex is \n, so your script would be

var test = 'this\nis\na\ntest\nwith\newlines';
console.log(test.replace(/\n/g, ' '));

You can make your div HTML code and set it directly into body(Or any element) with following code:

var divStr = '<div class="text-warning">Some html</div>';
document.getElementsByTagName('body')[0].innerHTML += divStr;

Well, one practical use I've found out is reducing boiler plate code. For example:

void process_z_vec(vector<int>& vec)
{
  auto print_2d = [](const vector<int>& board, int bsize)
  {
    for(int i = 0; i<bsize; i++)
    {
      for(int j=0; j<bsize; j++)
      {
        cout << board[bsize*i+j] << " ";
      }
      cout << "\n";
    }
  };
  // Do sth with the vec.
  print_2d(vec,x_size);
  // Do sth else with the vec.
  print_2d(vec,y_size);
  //... 
}

Without lambda, you may need to do something for different bsize cases. Of course you could create a function but what if you want to limit the usage within the scope of the soul user function? the nature of lambda fulfills this requirement and I use it for that case.

To set a class completely, instead of adding one or removing one, use this:

$(this).attr("class","newclass");

Advantage of this is that you'll remove any class that might be set in there and reset it to how you like. At least this worked for me in one situation.

I assume that you've run yum upgrade. That will in general update you to the newest minor release.

Your main resources for determining the version are /etc/redhat_release and lsb_release -a

<sup> and <sub> tags work and are your only good solution for arbitrary text. Other solutions include:

Unicode

If the superscript (or subscript) you need is of a mathematical nature, Unicode may well have you covered.

I've compiled a list of all the Unicode super and subscript characters I could identify in this gist. Some of the more common/useful ones are:

• ° SUPERSCRIPT ZERO (U+2070)
• ¹ SUPERSCRIPT ONE (U+00B9)
• ² SUPERSCRIPT TWO (U+00B2)
• ³ SUPERSCRIPT THREE (U+00B3)
• n SUPERSCRIPT LATIN SMALL LETTER N (U+207F)

People also often reach for <sup> and <sub> tags in an attempt to render specific symbols like these:

• ™ TRADE MARK SIGN (U+2122)
• ® REGISTERED SIGN (U+00AE)
• ? SERVICE MARK (U+2120)

Assuming your editor supports Unicode, you can copy and paste the characters above directly into your document.

Alternatively, you could use the hex values above in an HTML character escape. Eg, ² instead of ². This works with GitHub (and should work anywhere else your Markdown is rendered to HTML) but is less readable when presented as raw text/Markdown.

Images

If your requirements are especially unusual, you can always just inline an image. The GitHub supported syntax is:

![Alt text goes here, if you'd like](path/to/image.png) 

You can use a full path (eg. starting with https:// or http://) but it's often easier to use a relative path, which will load the image from the repo, relative to the Markdown document.

If you happen to know LaTeX (or want to learn it) you could do just about any text manipulation imaginable and render it to an image. Sites like Quicklatex make this quite easy.

Since explode() returns an array, you can add square brackets directly to the end of that function, if you happen to know the position of the last array item.

$email = '[email protected]';
$provider = explode('@', $email)[1];
echo $provider; // example.com

Or another way is list():

$email = '[email protected]';
list($prefix, $provider) = explode('@', $email);
echo $provider; // example.com

If you don't know the position:

$path = 'one/two/three/four';
$dirs = explode('/', $path);
$last_dir = $dirs[count($dirs) - 1];
echo $last_dir; // four

I don't mention basics like syntax highlighting as I expect these by default.

This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?

We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

From spark 3.0

data_cl = reg_data.exceptAll(data_fr)

first step: use all https://example.in or ssl certificate URL , dont use http://example.in

second step: faceboook application setting->basic setting->add your domain or subdomain

third step: faceboook application login setting->Valid OAuth Redirect URIs->add your all redirect url after login

fourth step: faceboook application setting->advance setting->Domain Manager->add your domain name

do all this step then use your application id, application version ,app secret for setup

one of the best things about git is that you can change the work flow that works best for you.. I do use http://nvie.com/posts/a-successful-git-branching-model/ most of the time but you can use any workflow that fits your needs

I searched quickly for you, and it brought me here. I quote:

You will get this message if you're trying to add a constraint with a name that's already used somewhere else

To check constraints use the following SQL query:

SELECT
    constraint_name,
    table_name
FROM
    information_schema.table_constraints
WHERE
    constraint_type = 'FOREIGN KEY'
AND table_schema = DATABASE()
ORDER BY
    constraint_name;

Look for more information there, or try to see where the error occurs. Looks like a problem with a foreign key to me.

This worked for me:

pip install psycopg2-binary

Quote_Month (Worksheet!$D:$D) contains a formula (=TEXT(Worksheet!$E:$E,"mmm-yy"))to convert a date/time number from another column into a text based month reference.

You can use OR by adding + in Sumproduct. See this

=SUMPRODUCT((Quote_Value)*(Salesman="JBloggs")*(Days_To_Close<=90)*((Quote_Month="Cond1")+(Quote_Month="Cond2")+(Quote_Month="Cond3")))

You can also use:

Get-WmiObject -Class "Win32_computersystem" | Select *

This will show the same result as Format-List * used in the other answers here.

A couple of examples:

infix fun Double.f(fmt: String) = "%$fmt".format(this)
infix fun Double.f(fmt: Float) = "%${if (fmt < 1) fmt + 1 else fmt}f".format(this)

val pi = 3.14159265358979323

println("""pi = ${pi f ".2f"}""")
println("pi = ${pi f .2f}")

I've checked DamienG's answer in LinqPad. Instead of

g.Group.Max(s => s.uid)

should be

g.Max(s => s.uid)

Thank you!

To show a problem is NP complete, you need to:

Show it is in NP

In other words, given some information C, you can create a polynomial time algorithm V that will verify for every possible input X whether X is in your domain or not.

Example

Prove that the problem of vertex covers (that is, for some graph G, does it have a vertex cover set of size k such that every edge in G has at least one vertex in the cover set?) is in NP:

• our input X is some graph G and some number k (this is from the problem definition)

• Take our information C to be "any possible subset of vertices in graph G of size k"

• Then we can write an algorithm V that, given G, k and C, will return whether that set of vertices is a vertex cover for G or not, in polynomial time.

Then for every graph G, if there exists some "possible subset of vertices in G of size k" which is a vertex cover, then G is in NP.

Note that we do not need to find C in polynomial time. If we could, the problem would be in `P.

Note that algorithm V should work for every G, for some C. For every input there should exist information that could help us verify whether the input is in the problem domain or not. That is, there should not be an input where the information doesn't exist.

Prove it is NP Hard

This involves getting a known NP-complete problem like SAT, the set of boolean expressions in the form:

(A or B or C) and (D or E or F) and ...

where the expression is satisfiable, that is there exists some setting for these booleans, which makes the expression true.

Then reduce the NP-complete problem to your problem in polynomial time.

That is, given some input X for SAT (or whatever NP-complete problem you are using), create some input Y for your problem, such that X is in SAT if and only if Y is in your problem. The function f : X -> Y must run in polynomial time.

In the example above, the input Y would be the graph G and the size of the vertex cover k.

For a full proof, you'd have to prove both:

• that X is in SAT => Y in your problem

• and Y in your problem => X in SAT.

marcog's answer has a link with several other NP-complete problems you could reduce to your problem.

Footnote: In step 2 (Prove it is NP-hard), reducing another NP-hard (not necessarily NP-complete) problem to the current problem will do, since NP-complete problems are a subset of NP-hard problems (that are also in NP).

As specified by the top answer, I used the following in the code behind the button control.

Private Sub btnClose_Click()
    Unload Me
End Sub

In doing so, it will not attempt to unload a control, but rather will unload the user form where the button control resides. The "Me" keyword refers to the user form object even when called from a control on the user form. If you are getting errors with this technique, there are a couple of possible reasons.

1. You could be entering the code in the wrong place (such as a separate module)

2. You might be using an older version of Office. I'm using Office 2013. I've noticed that VBA changes over time.

From my experience, the use of the the DoCmd.... method is more specific to the macro features in MS Access, but not commonly used in Excel VBA.

Under normal (out of the box) conditions, the code above should work just fine.

The following commands are available with .NET Core SDK 2.1 (v2.1.300):

To list all installed .NET Core SDKs use: dotnet --list-sdks

To list all installed .NET Core runtimes use dotnet --list-runtimes

(tested on Windows as of writing, 03 Jun 2018, and again on 23 Aug 2018)

Update as of 24 Oct 2018: Better option is probably now dotnet --info in a terminal or PowerShell window as already mentioned in other answers.

For frequent uses of this command I found it easy to add the location of C:\xampp\apache\bin to the PATH. Use whatever directory you have this installed in.

Then you can run from any directory in command line:

httpd -k restart

The answer above that suggests httpd -k -restart is actually a typo. You can see the commands by running httpd /?

Yes, you need to import the operator:

import 'rxjs/add/operator/catch';

Or import Observable this way:

import {Observable} from 'rxjs/Rx';

But in this case, you import all operators.

I've tried both these and still get failure due to conflicts. At the end of my patience, I cloned master in another location, copied everything into the other branch and committed it. which let me continue. The "-X theirs" option should have done this for me, but it did not.

For getting straight to "who is blocked/blocking" I combined/abbreviated sp_who and sp_lock into a single query which gives a nice overview of who has what object locked to what level.

NB the [Xclusive lock for command] column can be misleading -- it shows the current command for that spid; but the X lock could have been triggered by an earlier command in the transaction.

You should never use the unidirectional @OneToMany annotation because:

1. It generates inefficient SQL statements
2. It creates an extra table which increases the memory footprint of your DB indexes

Now, in your first example, both sides are owning the association, and this is bad.

While the @JoinColumn would let the @OneToMany side in charge of the association, it's definitely not the best choice. Therefore, always use the mappedBy attribute on the @OneToMany side.

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<APost> aPosts;

    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<BPost> bPosts;
}

public class BPost extends Post {

    @ManyToOne(fetch=FetchType.LAZY)    
    public User user;
}

public class APost extends Post {

     @ManyToOne(fetch=FetchType.LAZY) 
     public User user;
}

Here is the complete class which performs the required operation:

import java.util.Scanner;

public class App {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        final int valid = 6;

        Scanner one = new Scanner(System.in);
        System.out.println("Enter your username: ");
        String s = one.nextLine();

        if (s.length() < valid) {
            System.out.println("Enter a valid username");
            System.out.println(
                "User name must contain " + valid + " characters");
            System.out.println("Enter again: ");
            s = one.nextLine();
        }

        System.out.println("Username accepted: " + s);

        Scanner two = new Scanner(System.in);
        System.out.println("Enter your age: ");
        int a = two.nextInt();
        System.out.println("Age accepted: " + a);

        Scanner three = new Scanner(System.in);
        System.out.println("Enter your sex: ");
        String sex = three.nextLine();
        System.out.println("Sex accepted: " + sex);
    }
}

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/

It happens because you have not installed the minSdkVersion or targetSdkVersion in you’re computer. I've tested it right now.

For example, if you have those lines in your Manifest.xml:

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

And you have installed only the API17 in your computer, it will report you an error. If you want to test it, try installing the other API version (in this case, API 8).

Even so, it's not an important error. It doesn't mean that your app is wrong.

Sorry about my expression. English is not my language. Bye!

well,

I used System.setProperty("java.net.preferIPv4Stack" , "true"); and it works from JAVA, but it doesn't work on JBOSS AS7.

Here is my work around solution,

Add the below line to the end of the file ${JBOSS_HOME}/bin/standalone.conf.bat (just after :JAVA_OPTS_SET )

set "JAVA_OPTS=%JAVA_OPTS% -Djava.net.preferIPv4Stack=true"

Note: restart JBoss server

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

Just right click on a table and select "backup". The popup will show various options, including "Format", select "plain" and you get plain SQL.

pgAdmin is just using pg_dump to create the dump, also when you want plain SQL.

It uses something like this:

pg_dump --user user --password --format=plain --table=tablename --inserts --attribute-inserts etc.

fs/promises and fs.Dirent

Here's an efficient, non-blocking ls program using Node's fast fs.Dirent objects and fs/promises module. This approach allows you to skip wasteful fs.exist or fs.stat calls on every path -

// main.js
import { readdir } from "fs/promises"
import { join } from "path"

async function* ls (path = ".")
{ yield path
  for (const dirent of await readdir(path, { withFileTypes: true }))
    if (dirent.isDirectory())
      yield* ls(join(path, dirent.name))
    else
      yield join(path, dirent.name)
}

async function* empty () {}

async function toArray (iter = empty())
{ let r = []
  for await (const x of iter)
    r.push(x)
  return r
}

toArray(ls(".")).then(console.log, console.error)

Let's get some sample files so we can see ls working -

$ yarn add immutable     # (just some example package)
$ node main.js

[
  '.',
  'main.js',
  'node_modules',
  'node_modules/.yarn-integrity',

The answer is due to the fact that Google Chrome uses an SQLite file to save cookies. It resides under:

C:\Users\<your_username>\AppData\Local\Google\Chrome\User Data\Default\

inside Cookies file. (which is an SQLite database file)

So it's not a file stored on hard drive but a row in an SQLite database file which can be read by a third party program such as: SQLite Database Browser

EDIT: Thanks to @Chexpir, it is also good to know that the values are stored encrypted.

You don't have to click anything. Use find by xpath or whatever you choose and then use send keys

For your example: HTML:

<select id="fruits01" class="select" name="fruits">
    <option value="0">Choose your fruits:</option>
    <option value="1">Banana</option>
    <option value="2">Mango</option>
</select>

Python:

fruit_field = browser.find_element_by_xpath("//input[@name='fruits']")
fruit_field.send_keys("Mango")

That's it.

The fastest way, to get a hash string for password store purposes, is a following code:

    internal static string GetStringSha256Hash(string text)
    {
        if (String.IsNullOrEmpty(text))
            return String.Empty;

        using (var sha = new System.Security.Cryptography.SHA256Managed())
        {
            byte[] textData = System.Text.Encoding.UTF8.GetBytes(text);
            byte[] hash = sha.ComputeHash(textData);
            return BitConverter.ToString(hash).Replace("-", String.Empty);
        }
    }

Remarks:

• if the method is invoked often, the creation of sha variable should be refactored into a class field;
• output is presented as encoded hex string;

For Kotlin, You can use something like this :

object FileUtils {

   fun Context.getFileName(uri: Uri): String?
        = when (uri.scheme) {
            ContentResolver.SCHEME_FILE -> File(uri.path).name
            ContentResolver.SCHEME_CONTENT -> getCursorContent(uri)
            else -> null
        }

    private fun Context.getCursorContent(uri: Uri): String? 
        = try {
            contentResolver.query(uri, null, null, null, null)?.let { cursor ->
                cursor.run {
                    if (moveToFirst()) getString(getColumnIndex(OpenableColumns.DISPLAY_NAME))
                    else null
                }.also { cursor.close() }
            }
        } catch (e : Exception) { null }

I think there's cleaner way where you don't have to create a new webclient (and it'll work with 3rd party libraries as well)

internal static class MyWebRequestCreator
{
    private static IWebRequestCreate myCreator;

    public static IWebRequestCreate MyHttp
    {
        get
        {
            if (myCreator == null)
            {
                myCreator = new MyHttpRequestCreator();
            }
            return myCreator;
        }
    }

    private class MyHttpRequestCreator : IWebRequestCreate
    {
        public WebRequest Create(Uri uri)
        {
            var req = System.Net.WebRequest.CreateHttp(uri);
            req.CookieContainer = new CookieContainer();
            return req;
        }
    }
}

Now all you have to do is opt in for which domains you want to use this:

    WebRequest.RegisterPrefix("http://example.com/", MyWebRequestCreator.MyHttp);

That means ANY webrequest that goes to example.com will now use your custom webrequest creator, including the standard webclient. This approach means you don't have to touch all you code. You just call the register prefix once and be done with it. You can also register for "http" prefix to opt in for everything everywhere.

Step 1) Create Profile and Account

You need to create a profile and account using the Configure Database Mail Wizard which can be accessed from the Configure Database Mail context menu of the Database Mail node in Management Node. This wizard is used to manage accounts, profiles, and Database Mail global settings.

Step 2)

RUN:

sp_CONFIGURE 'show advanced', 1
GO
RECONFIGURE
GO
sp_CONFIGURE 'Database Mail XPs', 1
GO
RECONFIGURE
GO

Step 3)

USE msdb
GO
EXEC sp_send_dbmail @profile_name='yourprofilename',
@recipients='[email protected]',
@subject='Test message',
@body='This is the body of the test message.
Congrates Database Mail Received By you Successfully.'

To loop through the table

DECLARE @email_id NVARCHAR(450), @id BIGINT, @max_id BIGINT, @query NVARCHAR(1000)

SELECT @id=MIN(id), @max_id=MAX(id) FROM [email_adresses]

WHILE @id<=@max_id
BEGIN
    SELECT @email_id=email_id 
    FROM [email_adresses]

    set @query='sp_send_dbmail @profile_name=''yourprofilename'',
                        @recipients='''+@email_id+''',
                        @subject=''Test message'',
                        @body=''This is the body of the test message.
                        Congrates Database Mail Received By you Successfully.'''

    EXEC @query
    SELECT @id=MIN(id) FROM [email_adresses] where id>@id

END

For commenting out multiple lines of code in Python is to simply use a # single-line comment on every line:

# This is comment 1
# This is comment 2 
# This is comment 3

For writing “proper” multi-line comments in Python is to use multi-line strings with the """ syntax Python has the documentation strings (or docstrings) feature. It gives programmers an easy way of adding quick notes with every Python module, function, class, and method.

'''
This is
multiline
comment
'''

Also, mention that you can access docstring by a class object like this

myobj.__doc__

zip is its own inverse! Provided you use the special * operator.

>>> zip(*[('a', 1), ('b', 2), ('c', 3), ('d', 4)])
[('a', 'b', 'c', 'd'), (1, 2, 3, 4)]

The way this works is by calling zip with the arguments:

zip(('a', 1), ('b', 2), ('c', 3), ('d', 4))

… except the arguments are passed to zip directly (after being converted to a tuple), so there's no need to worry about the number of arguments getting too big.

I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:

My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.

private void startCreation(){
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_PICK);
    Uri startDir = Uri.fromFile(new File("/sdcard"));

    intent.setDataAndType(startDir,
            "vnd.android.cursor.dir/lysesoft.andexplorer.file");
    intent.putExtra("browser_filter_extension_whitelist", "*.csv");
    intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
    intent.putExtra("browser_title_background_color",
            getText(R.string.browser_title_background_color));
    intent.putExtra("browser_title_foreground_color",
            getText(R.string.browser_title_foreground_color));
    intent.putExtra("browser_list_background_color",
            getText(R.string.browser_list_background_color));
    intent.putExtra("browser_list_fontscale", "120%");
    intent.putExtra("browser_list_layout", "2");

    try{
         ApplicationInfo info = getPackageManager()
                                 .getApplicationInfo("lysesoft.andexplorer", 0 );

            startActivityForResult(intent, PICK_REQUEST_CODE);
    } catch( PackageManager.NameNotFoundException e ){
        showInstallResultMessage(R.string.error_install_andexplorer);
    } catch (Exception e) {
        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

If you are going to ALTER Table column and immediate UPDATE the table including the new column in the same script. Make sure that use GO command to after line of code of alter table as below.

ALTER TABLE Location 
ADD TransitionType SMALLINT NULL
GO   

UPDATE Location SET TransitionType =  4

ALTER TABLE Location 
    ALTER COLUMN TransitionType SMALLINT NOT NULL

Here's what I do:

echo $QUERY | \
  mysql -B  $MYSQL_OPTS | \
  perl -F"\t" -lane 'print join ",", map {s/"/""/g; /^[\d.]+$/ ? $_ : qq("$_")} @F ' | \
  mail -s 'report' person@address

The perl script (sniped from elsewhere) does a nice job of converting the tab spaced fields to CSV.

This does it:

Do
   c = c + 1
Loop While Cells(c, "A").Value <> ""

'prints the last empty row
Debug.Print c

I noticed that every now and then I need to Google fopen all over again, just to build a mental image of what the primary differences between the modes are. So, I thought a diagram will be faster to read next time. Maybe someone else will find that helpful too.

Generally speaking, this is the pattern I use:

• HTTP GET - SELECT/Request
• HTTP PUT - UPDATE
• HTTP POST - INSERT/Create
• HTTP DELETE - DELETE

var timeZoneInfos = TimeZoneInfo.GetSystemTimeZones();

The above gives you a list of timezones, which includes the ids.

//The IMPERATIVE way
int a = ...
int b = ...    

int c = 0; //1. there is mutable data
c = a+b;   //2. statements (our +, our =) are used to update existing data (variable c)

An imperative program = sequence of statements that change existing data.

Focus on WHAT = our mutating data (modifiable values aka variables).

To chain imperative statements = use procedures (and/or oop).

//The FUNCTIONAL way
const int a = ... //data is always immutable
const int b = ... //data is always immutable

//1. declare pure functions; we use statements to create "new" data (the result of our +), but nothing is ever "changed"
int add(x, y) 
{
   return x+y;
} 

//2. usage = call functions to get new data
const int c = add(a,b); //c can only be assigned (=) once (const)

A functional program = a list of functions "explaining" how new data can be obtained.

Focus on HOW = our function add.

To chain functional "statements" = use function composition.

These fundamental distinctions have deep implications.

Serious software has a lot of data and a lot of code.

So same data (variable) is used in multiple parts of the code.

A. In an imperative program, the mutability of this (shared) data causes issues

• code is hard to understand/maintain (since data can be modified in different locations/ways/moments)
• parallelizing code is hard (only one thread can mutate a memory location at the time) which means mutating accesses to same variable have to be serialized = developer must write additional code to enforce this serialized access to shared resources, typically via locks/semaphores

As an advantage: data is really modified in place, less need to copy. (some performance gains)

B. On the other hand, functional code uses immutable data which does not have such issues. Data is readonly so there are no race conditions. Code can be easily parallelized. Results can be cached. Much easier to understand.

As a disadvantage: data is copied a lot in order to get "modifications".

Ctrl + Shift + / works well for me on Windows.

If you've already assigned the variables using the npm module dotenv, then they should show up in your global variables. That module is here.

While running the debugger, go to your variables tab (right click to reopen if not visible) and then open "global" and then "process." There should then be an env section...

Donning asbestos longjohns...

Yesterday my title with Packt Publications, Reactive Programming with JavaScript. It isn't really a Node.js-centric title; early chapters are intended to cover theory, and later code-heavy chapters cover practice. Because I didn't really think it would be appropriate to fail to give readers a webserver, Node.js seemed by far the obvious choice. The case was closed before it was even opened.

I could have given a very rosy view of my experience with Node.js. Instead I was honest about good points and bad points I encountered.

Let me include a few quotes that are relevant here:

Warning: Node.js and its ecosystem are hot--hot enough to burn you badly!

When I was a teacher’s assistant in math, one of the non-obvious suggestions I was told was not to tell a student that something was “easy.” The reason was somewhat obvious in retrospect: if you tell people something is easy, someone who doesn’t see a solution may end up feeling (even more) stupid, because not only do they not get how to solve the problem, but the problem they are too stupid to understand is an easy one!

There are gotchas that don’t just annoy people coming from Python / Django, which immediately reloads the source if you change anything. With Node.js, the default behavior is that if you make one change, the old version continues to be active until the end of time or until you manually stop and restart the server. This inappropriate behavior doesn’t just annoy Pythonistas; it also irritates native Node.js users who provide various workarounds. The StackOverflow question “Auto-reload of files in Node.js” has, at the time of this writing, over 200 upvotes and 19 answers; an edit directs the user to a nanny script, node-supervisor, with homepage at http://tinyurl.com/reactjs-node-supervisor. This problem affords new users with great opportunity to feel stupid because they thought they had fixed the problem, but the old, buggy behavior is completely unchanged. And it is easy to forget to bounce the server; I have done so multiple times. And the message I would like to give is, “No, you’re not stupid because this behavior of Node.js bit your back; it’s just that the designers of Node.js saw no reason to provide appropriate behavior here. Do try to cope with it, perhaps taking a little help from node-supervisor or another solution, but please don’t walk away feeling that you’re stupid. You’re not the one with the problem; the problem is in Node.js’s default behavior.”

This section, after some debate, was left in, precisely because I don't want to give an impression of “It’s easy.” I cut my hands repeatedly while getting things to work, and I don’t want to smooth over difficulties and set you up to believe that getting Node.js and its ecosystem to function well is a straightforward matter and if it’s not straightforward for you too, you don’t know what you’re doing. If you don’t run into obnoxious difficulties using Node.js, that’s wonderful. If you do, I would hope that you don’t walk away feeling, “I’m stupid—there must be something wrong with me.” You’re not stupid if you experience nasty surprises dealing with Node.js. It’s not you! It’s Node.js and its ecosystem!

The Appendix, which I did not really want after the rising crescendo in the last chapters and the conclusion, talks about what I was able to find in the ecosystem, and provided a workaround for moronic literalism:

Another database that seemed like a perfect fit, and may yet be redeemable, is a server-side implementation of the HTML5 key-value store. This approach has the cardinal advantage of an API that most good front-end developers understand well enough. For that matter, it’s also an API that most not-so-good front-end developers understand well enough. But with the node-localstorage package, while dictionary-syntax access is not offered (you want to use localStorage.setItem(key, value) or localStorage.getItem(key), not localStorage[key]), the full localStorage semantics are implemented, including a default 5MB quota—WHY? Do server-side JavaScript developers need to be protected from themselves?

For client-side database capabilities, a 5MB quota per website is really a generous and useful amount of breathing room to let developers work with it. You could set a much lower quota and still offer developers an immeasurable improvement over limping along with cookie management. A 5MB limit doesn’t lend itself very quickly to Big Data client-side processing, but there is a really quite generous allowance that resourceful developers can use to do a lot. But on the other hand, 5MB is not a particularly large portion of most disks purchased any time recently, meaning that if you and a website disagree about what is reasonable use of disk space, or some site is simply hoggish, it does not really cost you much and you are in no danger of a swamped hard drive unless your hard drive was already too full. Maybe we would be better off if the balance were a little less or a little more, but overall it’s a decent solution to address the intrinsic tension for a client-side context.

However, it might gently be pointed out that when you are the one writing code for your server, you don’t need any additional protection from making your database more than a tolerable 5MB in size. Most developers will neither need nor want tools acting as a nanny and protecting them from storing more than 5MB of server-side data. And the 5MB quota that is a golden balancing act on the client-side is rather a bit silly on a Node.js server. (And, for a database for multiple users such as is covered in this Appendix, it might be pointed out, slightly painfully, that that’s not 5MB per user account unless you create a separate database on disk for each user account; that’s 5MB shared between all user accounts together. That could get painful if you go viral!) The documentation states that the quota is customizable, but an email a week ago to the developer asking how to change the quota is unanswered, as was the StackOverflow question asking the same. The only answer I have been able to find is in the Github CoffeeScript source, where it is listed as an optional second integer argument to a constructor. So that’s easy enough, and you could specify a quota equal to a disk or partition size. But besides porting a feature that does not make sense, the tool’s author has failed completely to follow a very standard convention of interpreting 0 as meaning “unlimited” for a variable or function where an integer is to specify a maximum limit for some resource use. The best thing to do with this misfeature is probably to specify that the quota is Infinity:

if (typeof localStorage === 'undefined' || localStorage === null)
  {      
  var LocalStorage = require('node-localstorage').LocalStorage;
  localStorage = new LocalStorage(__dirname + '/localStorage',
    Infinity);
  }

Swapping two comments in order:

People needlessly shot themselves in the foot constantly using JavaScript as a whole, and part of JavaScript being made respectable language was a Douglas Crockford saying in essence, “JavaScript as a language has some really good parts and some really bad parts. Here are the good parts. Just forget that anything else is there.” Perhaps the hot Node.js ecosystem will grow its own “Douglas Crockford,” who will say, “The Node.js ecosystem is a coding Wild West, but there are some real gems to be found. Here’s a roadmap. Here are the areas to avoid at almost any cost. Here are the areas with some of the richest paydirt to be found in ANY language or environment.”

Perhaps someone else can take those words as a challenge, and follow Crockford’s lead and write up “the good parts” and / or “the better parts” for Node.js and its ecosystem. I’d buy a copy!

And given the degree of enthusiasm and sheer work-hours on all projects, it may be warranted in a year, or two, or three, to sharply temper any remarks about an immature ecosystem made at the time of this writing. It really may make sense in five years to say, “The 2015 Node.js ecosystem had several minefields. The 2020 Node.js ecosystem has multiple paradises.”

This is a faster/simpler (and prototypical) variation of the function that Josh posted:

String.prototype.format = String.prototype.f = function() {
    var s = this,
        i = arguments.length;

    while (i--) {
        s = s.replace(new RegExp('\\{' + i + '\\}', 'gm'), arguments[i]);
    }
    return s;
};

Usage:

'Added {0} by {1} to your collection'.f(title, artist)
'Your balance is {0} USD'.f(77.7) 

I use this so much that I aliased it to just f, but you can also use the more verbose format. e.g. 'Hello {0}!'.format(name)

.html - DOS has been dead for a long time. But it doesn't really make much difference in the end.

In dash and other shells, you can use

printf "%d\n" (your hexadecimal number)

to convert a hexadecimal number to decimal. This is not bash, or ksh, specific.

Unfortunately, you don't. That is part of how the import syntax works and it is important that it does so -- remember def is actually something executed, if Python did not execute the import, you'd be, well, stuck without functions.

Since you probably have access to the file, though, you might be able to look and see what causes the error. It might be possible to modify your environment to prevent the error from happening.

Write a dict subclass that accepts a list of keys as an "item" and returns a "slice" of the dictionary:

class SliceableDict(dict):
    default = None
    def __getitem__(self, key):
        if isinstance(key, list):   # use one return statement below
            # uses default value if a key does not exist
            return {k: self.get(k, self.default) for k in key}
            # raises KeyError if a key does not exist
            return {k: self[k] for k in key}
            # omits key if it does not exist
            return {k: self[k] for k in key if k in self}
        return dict.get(self, key)

Usage:

d = SliceableDict({1:2, 3:4, 5:6, 7:8})
d[[1, 5]]   # {1: 2, 5: 6}

Or if you want to use a separate method for this type of access, you can use * to accept any number of arguments:

class SliceableDict(dict):
    def slice(self, *keys):
        return {k: self[k] for k in keys}
        # or one of the others from the first example

d = SliceableDict({1:2, 3:4, 5:6, 7:8})
d.slice(1, 5)     # {1: 2, 5: 6}
keys = 1, 5
d.slice(*keys)    # same

This time you found your problem. If next time you are less lucky and cannot figure it out, you can use plan freezing and stop worrying about wrong execution plan.

Try this:

def word(string, num)
    string = 'Smith'
    string[0..(num-1)]
end

Can't copy the icons here, but here are the descriptions:

• Show: Present the content in the detail or master area depending on the content of the screen.

  If the app is displaying a master and detail view, the content is pushed onto the detail area. If the app is only displaying the master or the detail, the content is pushed on top of the current view controller stack.

• Show Detail: Present the content in the detail area.

  If the app is displaying a master and detail view, the new content replaces the current detail. If the app is only displaying the master or the detail, the content replaces the top of the current view controller stack.

• Present Modally: Present the content modally.

• Present as Popover: Present the content as a popover anchored to an existing view.

• Custom: Create your own behaviors by using a custom segue.

Here is the changeLocation example from this article http://www.yearofmoo.com/2012/10/more-angularjs-magic-to-supercharge-your-webapp.html#apply-digest-and-phase

//be sure to inject $scope and $location
var changeLocation = function(url, forceReload) {
  $scope = $scope || angular.element(document).scope();
  if(forceReload || $scope.$$phase) {
    window.location = url;
  }
  else {
    //only use this if you want to replace the history stack
    //$location.path(url).replace();

    //this this if you want to change the URL and add it to the history stack
    $location.path(url);
    $scope.$apply();
  }
};

Here is a quick and simple solution using PowerShell:

powershell.exe -nologo -noprofile -command "& { $shell = New-Object -COM Shell.Application; $target = $shell.NameSpace('C:\extractToThisDirectory'); $zip = $shell.NameSpace('C:\extractThis.zip'); $target.CopyHere($zip.Items(), 16); }"

This uses the built-in extract functionality of the Explorer and will also show the typical extract progress window. The second parameter 16 to CopyHere answers all questions with yes.

The JSON format can contain only those types of value:

• string
• number
• object
• array
• true
• false
• null

An image is of the type "binary" which is none of those. So you can't directly insert an image into JSON. What you can do is convert the image to a textual representation which can then be used as a normal string.

The most common way to achieve that is with what's called base64. Basically, instead of encoding it as 1 and 0s, it uses a range of 64 characters which makes the textual representation of it more compact. So for example the number '64' in binary is represented as 1000000, while in base64 it's simply one character: =.

There are many ways to encode your image in base64 depending on if you want to do it in the browser or not.

Note that if you're developing a web application, it will be way more efficient to store images separately in binary form, and store paths to those images in your JSON or elsewhere. That also allows your client's browser to cache the images.

**The following method does the way you want. It filters the array based on all properties values. **

    var standardsList = [
  { "Grade": "Math K", "Domain": "Counting & Cardinality" },
  { "Grade": "Math K", "Domain": "Counting & Cardinality" },
  { "Grade": "Math K", "Domain": "Counting & Cardinality" },
  { "Grade": "Math K", "Domain": "Counting & Cardinality" },
  { "Grade": "Math K", "Domain": "Geometry" },
  { "Grade": "Math 1", "Domain": "Counting & Cardinality" },
  { "Grade": "Math 1", "Domain": "Counting & Cardinality" },
  { "Grade": "Math 1", "Domain": "Orders of Operation" },
  { "Grade": "Math 2", "Domain": "Geometry" },
  { "Grade": "Math 2", "Domain": "Geometry" }
];

const removeDupliactes = (values) => {
  let concatArray = values.map(eachValue => {
    return Object.values(eachValue).join('')
  })
  let filterValues = values.filter((value, index) => {
    return concatArray.indexOf(concatArray[index]) === index

  })
  return filterValues
}
removeDupliactes(standardsList) 

Results this

[{Grade: "Math K", Domain: "Counting & Cardinality"}

{Grade: "Math K", Domain: "Geometry"}

{Grade: "Math 1", Domain: "Counting & Cardinality"}

{Grade: "Math 1", Domain: "Orders of Operation"}

{Grade: "Math 2", Domain: "Geometry"}] 

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

It's better to create a new factor variable using cut(). I've added a few options using ggplot2 also.

df <- data.frame(
  X1=seq(0, 5, by=0.001),
  X2=rnorm(df$X1, mean = 3.5, sd = 1.5)
)

# Create new variable for plotting
df$Colour <- cut(df$X2, breaks = c(-Inf, 1, 3, +Inf), 
                 labels = c("low", "medium", "high"), 
                 right = FALSE)

### Base Graphics

plot(df$X1, df$X2, 
     col = df$Colour, ylim = c(0, 10), xlab = "POS", 
     ylab = "CS", main = "Plot Title", pch = 21)

plot(df$X1,df$X2, 
     col = df$Colour, ylim = c(0, 10), xlab = "POS", 
     ylab = "CS", main = "Plot Title", pch = 19, cex = 0.5)

# Using `with()` 

with(df, 
     plot(X1, X2, xlab="POS", ylab="CS", col = Colour, pch=21, cex=1.4)
     )

# Using ggplot2
library(ggplot2)

# qplot()
qplot(df$X1, df$X2, colour = df$Colour)

# ggplot()
p <- ggplot(df, aes(X1, X2, colour = Colour)) 
p <- p + geom_point() + xlab("POS") + ylab("CS")
p

p + facet_grid(Colour~., scales = "free")

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private static MainActivity instance;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        instance = this;
    }

    public static MainActivity getInstance() {
        return instance;
    }

    public void myMethod() {
       // do something...
    }
)

AnotherClass.java

public Class AnotherClass() {
     // call this method
     MainActivity.getInstance().myMethod();
}

You can easily write the method to do that :

  public static String toCamelCase(final String init) {
    if (init == null)
        return null;

    final StringBuilder ret = new StringBuilder(init.length());

    for (final String word : init.split(" ")) {
        if (!word.isEmpty()) {
            ret.append(Character.toUpperCase(word.charAt(0)));
            ret.append(word.substring(1).toLowerCase());
        }
        if (!(ret.length() == init.length()))
            ret.append(" ");
    }

    return ret.toString();
}

Once after we build the jar will have the resource files under BOOT-INF/classes or target/classes folder, which is in classpath, use the below method and pass the file under the src/main/resources as method call getAbsolutePath("certs/uat_staging_private.ppk"), even we can place this method in Utility class and the calling Thread instance will be taken to load the ClassLoader to get the resource from class path.

 public String getAbsolutePath(String fileName) throws IOException {
      return Thread.currentThread().getContextClassLoader().getResource(fileName).getFile();
  }

we can add the below tag to tag in pom.xml to include these resource files to build target/classes folder

<resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.ppk</include>
            </includes>
        </resource>
</resources>

This worked for me: Create a custom contract resolver which has a public property called AllowList of string array type. In your action, modify that property depending on what the action needs to return.

1. create a custom contract resolver:

public class PublicDomainJsonContractResolverOptIn : DefaultContractResolver
{
    public string[] AllowList { get; set; }

    protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
    {
        IList<JsonProperty> properties = base.CreateProperties(type, memberSerialization);

        properties = properties.Where(p => AllowList.Contains(p.PropertyName)).ToList();
        return properties;
    }
}

2. use custom contract resolver in action

[HttpGet]
public BinaryImage Single(int key)
{
    //limit properties that are sent on wire for this request specifically
    var contractResolver = Configuration.Formatters.JsonFormatter.SerializerSettings.ContractResolver as PublicDomainJsonContractResolverOptIn;
    if (contractResolver != null)
        contractResolver.AllowList = new string[] { "Id", "Bytes", "MimeType", "Width", "Height" };

    BinaryImage image = new BinaryImage { Id = 1 };
    //etc. etc.
    return image;
}

This approach allowed me to allow/disallow for specific request instead of modifying the class definition. And if you don't need XML serialization, don't forget to turn it off in your App_Start\WebApiConfig.cs or your API will return blocked properties if the client requests xml instead of json.

//remove xml serialization
var appXmlType = config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml");
config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType);

If you could not find Local DTC in the component services try to run this PowerShell script first:

$DTCSettings = @(
"NetworkDtcAccess",               # Network DTC Access
"NetworkDtcAccessClients",        # Allow Remote Clients        ( Client and Administration)
"NetworkDtcAccessAdmin",          # Allow Remote Administration ( Client and Administration)
"NetworkDtcAccessTransactions",   #                (Transaction Manager Communication )
"NetworkDtcAccessInbound",        # Allow Inbound  (Transaction Manager Communication )
"NetworkDtcAccessOutbound" ,      # Allow Outbound (Transaction Manager Communication )
"XaTransactions",                 # Enable XA Transactions
"LuTransactions"                  # Enable SNA LU 6.2 Transactions
)
foreach($setting in $DTCSettings)
{
Set-ItemProperty -Path HKLM:\Software\Microsoft\MSDTC\Security -Name $setting -Value 1
} 
Restart-Service msdtc

And it appears!

Simply mark any method you need to fake as virtual (and not private). Then you will be able to create a fake that can override the method.

If you use new Mock<Type> and you don't have a parameterless constructor then you can pass the parameters as the arguments of the above call as it takes a type of param Objects

I was having trouble with a local DB.

I was able to solve this problem by stopping SQL server, and then starting SQL server, and then using the SSMS UI to change the DB properties to Multi_User.

The DB went into "Single User" Mode when i was attempting to restore a backup. I hadn't created a backup of the target database before attempting to restore (SQL 2017). this will get you every time.

Stop SQL Server, Start SQL Server, then run the above Scripts or use the UI.

I did a quick test in both node and chrome and found in both cases += is faster:

var profile = func => { 
    var start = new Date();
    for (var i = 0; i < 10000000; i++) func('test');
    console.log(new Date() - start);
}
profile(x => "testtesttesttesttest");
profile(x => `${x}${x}${x}${x}${x}`);
profile(x => x + x + x + x + x );
profile(x => { var s = x; s += x; s += x; s += x; s += x; return s; });
profile(x => [x, x, x, x, x].join(""));
profile(x => { var a = [x]; a.push(x); a.push(x); a.push(x); a.push(x); return a.join(""); });

results in node: 7.0.10

• assignment: 8
• template literals: 524
• plus: 382
• plus equals: 379
• array join: 1476
• array push join: 1651

results from chrome 86.0.4240.198:

• assignment: 6
• template literals: 531
• plus: 406
• plus equals: 403
• array join: 1552

The method you're using to read the http body response returns a byte slice:

func ReadAll(r io.Reader) ([]byte, error)

official documentation

You can convert []byte to a string by using

body, err := ioutil.ReadAll(resp.Body)
bodyString := string(body)

Use the CX register to count the loops

mov cx, 3
startloop:
   cmp cx, 0
   jz endofloop
   push cx
loopy:
   Call ClrScr
   pop cx
   dec cx
   jmp startloop
endofloop:
   ; Loop ended
   ; Do what ever you have to do here

This simply loops around 3 times calling ClrScr, pushing the CX register onto the stack, comparing to 0, jumping if ZeroFlag is set then jump to endofloop. Notice how the contents of CX is pushed/popped on/off the stack to maintain the flow of the loop.

I suspect you are running Android 6.0 Marshmallow (API 23) or later. If this is the case, you must implement runtime permissions before you try to read/write external storage.

DBeaver allows you connect to a DB2 database, run a query, and export the result-set to a CSV file that can be opened and fine-tuned in MS Excel or LibreOffice Calc.

To do this, all you have to do (in DBeaver) is right-click on the results grid (after running the query) and select "Export Resultset" from the context-menu.

This produces the dialog below, where you can ultimately save the result-set to a file as CSV, XML, or HTML:

select partition_name,column_name,high_value,partition_position
from ALL_TAB_PARTITIONS a , ALL_PART_KEY_COLUMNS b 
where table_name='YOUR_TABLE' and a.table_name = b.name;

This query lists the column name used as key and the allowed values. make sure, you insert the allowed values(high_value). Else, if default partition is defined, it would go there.

EDIT:

I presume, your TABLE DDL would be like this.

CREATE TABLE HE0_DT_INF_INTERFAZ_MES
  (
    COD_PAIS NUMBER,
    FEC_DATA NUMBER,
    INTERFAZ VARCHAR2(100)
  )
  partition BY RANGE(COD_PAIS, FEC_DATA)
  (
    PARTITION PDIA_98_20091023 VALUES LESS THAN (98,20091024)
  );

Which means I had created a partition with multiple columns which holds value less than the composite range (98,20091024);

That is first COD_PAIS <= 98 and Also FEC_DATA < 20091024

Combinations And Result:

98, 20091024     FAIL
98, 20091023     PASS
99, ********     FAIL
97, ********     PASS
 < 98, ********     PASS

So the below INSERT fails with ORA-14400; because (98,20091024) in INSERT is EQUAL to the one in DDL but NOT less than it.

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
                                  VALUES(98, 20091024, 'CTA');  2
INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
            *
ERROR at line 1:
ORA-14400: inserted partition key does not map to any partition

But, we I attempt (97,20091024), it goes through

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
  2                                    VALUES(97, 20091024, 'CTA');

1 row created.

Simple answer is that: Go to your console app's properties(project's properties).In the "Application" tab, just change the "Output type" to "Windows Application". That's all.

In prototypeJS, we have method isJSON. You can try that. Even json might help.

"something".isJSON();
// -> false
"\"something\"".isJSON();
// -> true
"{ foo: 42 }".isJSON();
// -> false
"{ \"foo\": 42 }".isJSON();

In my case I had relocated Web Deploy to another port, which was also the IIS port (not 80). I didn't realize at first, but even though there were no errors running both under the same port, seems Web Deploy was most likely responding first instead of IIS for some reason, causing this error. I just moved my IIS binding to another port and all is well. ;)

I'm quite happy with my "make a weak pin storage program" solution. Maybe it will help people who need a very simple binary file IO example to follow.

$ ls
WeakPin  my_pin_code.pin  weak_pin.c
$ ./WeakPin
Pin: 45 47 49 32
$ ./WeakPin 8 2
$ Need 4 ints to write a new pin!
$./WeakPin 8 2 99 49
Pin saved.
$ ./WeakPin
Pin: 8 2 99 49
$
$ cat weak_pin.c
// a program to save and read 4-digit pin codes in binary format

#include <stdio.h>
#include <stdlib.h>

#define PIN_FILE "my_pin_code.pin"

typedef struct { unsigned short a, b, c, d; } PinCode;


int main(int argc, const char** argv)
{
    if (argc > 1)  // create pin
    {
        if (argc != 5)
        {
            printf("Need 4 ints to write a new pin!\n");
            return -1;
        }
        unsigned short _a = atoi(argv[1]);
        unsigned short _b = atoi(argv[2]);
        unsigned short _c = atoi(argv[3]);
        unsigned short _d = atoi(argv[4]);
        PinCode pc;
        pc.a = _a; pc.b = _b; pc.c = _c; pc.d = _d;
        FILE *f = fopen(PIN_FILE, "wb");  // create and/or overwrite
        if (!f)
        {
            printf("Error in creating file. Aborting.\n");
            return -2;
        }

        // write one PinCode object pc to the file *f
        fwrite(&pc, sizeof(PinCode), 1, f);  

        fclose(f);
        printf("Pin saved.\n");
        return 0;
    }

    // else read existing pin
    FILE *f = fopen(PIN_FILE, "rb");
    if (!f)
    {
        printf("Error in reading file. Abort.\n");
        return -3;
    }
    PinCode pc;
    fread(&pc, sizeof(PinCode), 1, f);
    fclose(f);

    printf("Pin: ");
    printf("%hu ", pc.a);
    printf("%hu ", pc.b);
    printf("%hu ", pc.c);
    printf("%hu\n", pc.d);
    return 0;
}

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

You can always give regular expression as string, i.e. "ReGeX" + testVar + "ReGeX". You'll possibly have to escape some characters inside your string (e.g., double quote), but for most cases it's equivalent.

You can also use RegExp constructor to pass flags in (see the docs).

If you need to know the default collation for a newly created database use:

SELECT SERVERPROPERTY('Collation')

This is the server collation for the SQL Server instance that you are running.

As already pointed out by Nico Huysamen, finding multiple mode in Java 1.8 can be done alternatively as below.

import java.util.ArrayList;
import java.util.List;
import java.util.HashMap;
import java.util.Map;

public static void mode(List<Integer> numArr) {
    Map<Integer, Integer> freq = new HashMap<Integer, Integer>();;
    Map<Integer, List<Integer>> mode = new HashMap<Integer, List<Integer>>();

    int modeFreq = 1; //record the highest frequence
    for(int x=0; x<numArr.size(); x++) { //1st for loop to record mode
        Integer curr = numArr.get(x); //O(1)
        freq.merge(curr, 1, (a, b) -> a + b); //increment the frequency for existing element, O(1)
        int currFreq = freq.get(curr); //get frequency for current element, O(1)

        //lazy instantiate a list if no existing list, then
        //record mapping of frequency to element (frequency, element), overall O(1)
        mode.computeIfAbsent(currFreq, k -> new ArrayList<>()).add(curr);

        if(modeFreq < currFreq) modeFreq = currFreq; //update highest frequency
    }
    mode.get(modeFreq).forEach(x -> System.out.println("Mode = " + x)); //pretty print the result //another for loop to return result
}

Happy coding!

@jmp242 - the generic System.Object type does not contain the CloseMainWindow method, but statically casting the System.Diagnostics.Process type when collecting the ProcessList variable works for me. Updated code (from this answer) with this casting (and looping changed to use ForEach-Object) is below.

function Stop-Processes {
    param(
        [parameter(Mandatory=$true)] $processName,
                                     $timeout = 5
    )
    [System.Diagnostics.Process[]]$processList = Get-Process $processName -ErrorAction SilentlyContinue

    ForEach ($Process in $processList) {
        # Try gracefully first
        $Process.CloseMainWindow() | Out-Null
    }

    # Check the 'HasExited' property for each process
    for ($i = 0 ; $i -le $timeout; $i++) {
        $AllHaveExited = $True
        $processList | ForEach-Object {
            If (-NOT $_.HasExited) {
                $AllHaveExited = $False
            }                    
        }
        If ($AllHaveExited -eq $true){
            Return
        }
        Start-Sleep 1
    }
    # If graceful close has failed, loop through 'Stop-Process'
    $processList | ForEach-Object {
        If (Get-Process -ID $_.ID -ErrorAction SilentlyContinue) {
            Stop-Process -Id $_.ID -Force -Verbose
        }
    }
}

A combination of the regex and SimpleDateFormat is the right answer i believe. SimpleDateFormat does not catch exception if the individual components are invalid meaning, Format Defined: yyyy-mm-dd input: 201-0-12 No exception will be thrown.This case should have been handled. But with the regex as suggested by Sok Pomaranczowy and Baby will take care of this particular case.

you could probably use the gzip -t option to test the files integrity

http://linux.about.com/od/commands/l/blcmdl1_gzip.htm

from: http://unix.ittoolbox.com/groups/technical-functional/shellscript-l/how-to-test-file-integrity-of-targz-1138880

To test the gzip file is not corrupt:

gunzip -t file.tar.gz

To test the tar file inside is not corrupt:

gunzip -c file.tar.gz | tar -t > /dev/null

As part of the backup you could probably just run the latter command and check the value of $? afterwards for a 0 (success) value. If either the tar or the gzip has an issue, $? will have a non zero value.

The following two facts definitely point to memory leaks:

1. The error appears at different lines in your code,
2. The error reports a relatively small memory allocation.

I would first single out PDO, disabling all the other extensions and let it run overnight using something like Siege / Apache Bench (ab). You could also try running it using the cli interface (just make sure you keep the same memory limits).

You could use the memory_get_peak_usage() function at the end of your script to see how much memory PHP thinks it has been using.

From your comment that's 800 kB, which is okay; definitely not the gigantic amount of memory that would cause an out-of-memory ;-)

Lastly, though I wouldn't recommend upgrading to 5.4 at this point, upgrading to the latest 5.3.x is probably worth it due to multiple vulnerabilities and leaks that have been addressed since 5.3.1

Ctrl+C sends a SIGINT signal.

kill -INT <pid> sends a SIGINT signal too:

# Terminates the program (like Ctrl+C)
kill -INT 888
# Force kill
kill -9 888

Assuming 888 is your process ID.

Note that kill 888 sends a SIGTERM signal, which is slightly different, but will also ask for the program to stop. So if you know what you are doing (no handler bound to SIGINT in the program), a simple kill is enough.

To get the PID of the last command launched in your script, use $! :

# Launch script in background
./my_script.sh &
# Get its PID
PID=$!
# Wait for 2 seconds
sleep 2
# Kill it
kill $PID

Capitalize the app to App will surely work.

You can use the following command on the command prompt (cmd) on Windows:

py -3.3 -m pip install opencv-python

I made a video on how to install OpenCV Python on Windows in 1 minute here:

Hope it helps!

As this is the first result on google and there's no C++20 answer yet, here's how to use std::chrono to do this:

#include <chrono>

//...

using namespace std::chrono;
int64_t timestamp = duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();

In versions of C++ before 20, system_clock's epoch being Unix epoch is a de-facto convention, but it's not standardized. If you're not on C++20, use at your own risk.

For testing I just run multiple instances of httpd on different IP addresses, so I have php7 running on 192.168.0.70 and php5.6 running on 192.168.0.56. In production I have a site running an old oscommerce running php5.3 and I just have a different conf file for the site

httpd -f /etc/apache2/php70.conf
httpd -f /etc/apache2/php53.conf

It's also a clean way to have different php.ini files for different sites. If you just have a couple of sites if a nice way to keep things organized and you don't have to worry about more then 1 site at a time when you upgrade something

According to the documentation you need to specify the key store:

Protocol authhttps = new Protocol("https",  
      new AuthSSLProtocolSocketFactory(
          new URL("file:my.keystore"), "mypassword",
          new URL("file:my.truststore"), "mypassword"), 443); 

 HttpClient client = new HttpClient();
 client.getHostConfiguration().setHost("localhost", 443, authhttps);

You can try https://rubygems.org/gems/dates_from_string:

Find date in structure:

text = "get car from repair 2015-02-02 23:00:10"
dates_from_string = DatesFromString.new
dates_from_string.find_date(text)

=> ["2015-02-02 23:00:10"]

More specific:

$("#id1 p:contains('dog')").text($("#id1 p:contains('dog')").text().replace('dog', 'doll'));

Up and coming to the HTML5 scene is the download attribute. It's supported in Firefox and Chrome, and soon to come to IE11. Depending on your needs, you could use it instead of an AJAX request (or using window.location) so long as the file you want to download is on the same origin as your site.

You could always make the AJAX request/window.location a fallback by using some JavaScript to test if download is supported and if not, switching it to call window.location.

Original answer

You can't have an AJAX request open the download prompt since you physically have to navigate to the file to prompt for download. Instead, you could use a success function to navigate to download.php. This will open the download prompt but won't change the current page.

$.ajax({
    url: 'download.php',
    type: 'POST',
    success: function() {
        window.location = 'download.php';
    }
});

Even though this answers the question, it's better to just use window.location and avoid the AJAX request entirely.

What only worked for me is actually adding the module name to the xib file...

Sooo, the xib files look like this:

mymodule.MyViewController.xib (Module being the name of the proyect, usually)

HORRIBLE solution in my opinion, but that is supposedly how Apple wants us to do it now.

This question shows 3 possible work arounds back in beta 4 ... apparently Apple has not been very helpful in this situation according to some because they call it "Working as intended."

just add different .gitignore files to mini project 1 and mini project 2. Each of the .gitignore files should /node_modules and you're good to go.

My guess is, somehow the document is not fully loaded by the time the method is called. Have your code executing after the document is ready event.

Both classes Rectangle and Ellipse need to override both of the abstract methods.

To work around this, you have 3 options:

• Add the two methods
• Make each class that extends Shape abstract

• Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:

  abstract class Shape {
      // ...
      void draw(Graphics g);
  }
  

And

    class Rectangle extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

Finally

    class Ellipse extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

And you can switch in between them, like so:

    Shape shape = new Ellipse();
    shape.draw(/* ... */);

    shape = new Rectangle();
    shape.draw(/* ... */);

Again, just an example.

TEXT is used for large pieces of string data. If the length of the field exceeed a certain threshold, the text is stored out of row.

VARCHAR is always stored in row and has a limit of 8000 characters. If you try to create a VARCHAR(x), where x > 8000, you get an error:

Server: Msg 131, Level 15, State 3, Line 1

The size () given to the type ‘varchar’ exceeds the maximum allowed for any data type (8000)

These length limitations do not concern VARCHAR(MAX) in SQL Server 2005, which may be stored out of row, just like TEXT.

Note that MAX is not a kind of constant here, VARCHAR and VARCHAR(MAX) are very different types, the latter being very close to TEXT.

In prior versions of SQL Server you could not access the TEXT directly, you only could get a TEXTPTR and use it in READTEXT and WRITETEXT functions.

In SQL Server 2005 you can directly access TEXT columns (though you still need an explicit cast to VARCHAR to assign a value for them).

TEXT is good:

• If you need to store large texts in your database
• If you do not search on the value of the column
• If you select this column rarely and do not join on it.

VARCHAR is good:

• If you store little strings
• If you search on the string value
• If you always select it or use it in joins.

By selecting here I mean issuing any queries that return the value of the column.

By searching here I mean issuing any queries whose result depends on the value of the TEXT or VARCHAR column. This includes using it in any JOIN or WHERE condition.

As the TEXT is stored out of row, the queries not involving the TEXT column are usually faster.

Some examples of what TEXT is good for:

• Blog comments
• Wiki pages
• Code source

Some examples of what VARCHAR is good for:

• Usernames
• Page titles
• Filenames

As a rule of thumb, if you ever need you text value to exceed 200 characters AND do not use join on this column, use TEXT.

Otherwise use VARCHAR.

P.S. The same applies to UNICODE enabled NTEXT and NVARCHAR as well, which you should use for examples above.

P.P.S. The same applies to VARCHAR(MAX) and NVARCHAR(MAX) that SQL Server 2005+ uses instead of TEXT and NTEXT. You'll need to enable large value types out of row for them with sp_tableoption if you want them to be always stored out of row.

As mentioned above and here, TEXT is going to be deprecated in future releases:

The text in row option will be removed in a future version of SQL Server. Avoid using this option in new development work, and plan to modify applications that currently use text in row. We recommend that you store large data by using the varchar(max), nvarchar(max), or varbinary(max) data types. To control in-row and out-of-row behavior of these data types, use the large value types out of row option.

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

ginalx's answer should be set as the default one imo: this method allows for many optimizations.

The problem

Say that we have a list of items and on every item we want to include a menu that needs to be toggled. We include a toggle on a button that listens for a click event on itself (click)="toggle()", but we also want to toggle the menu whenever the user clicks outside of it. If the list of items grows and we attach a @HostListener('document:click') on every menu, then every menu loaded within the item will start listening for the click on the entire document, even when the menu is toggled off. Besides the obvious performance issues, this is unnecessary.

You can, for example, subscribe whenever the popup gets toggled via a click and start listening for "outside clicks" only then.

isActive: boolean = false;

// to prevent memory leaks and improve efficiency, the menu
// gets loaded only when the toggle gets clicked
private _toggleMenuSubject$: BehaviorSubject<boolean>;
private _toggleMenu$: Observable<boolean>;

private _toggleMenuSub: Subscription;
private _clickSub: Subscription = null;


constructor(
 ...
 private _utilitiesService: UtilitiesService,
 private _elementRef: ElementRef,
){
 ...
 this._toggleMenuSubject$ = new BehaviorSubject(false);
 this._toggleMenu$ = this._toggleMenuSubject$.asObservable();

}

ngOnInit() {
 this._toggleMenuSub = this._toggleMenu$.pipe(
      tap(isActive => {
        logger.debug('Label Menu is active', isActive)
        this.isActive = isActive;

        // subscribe to the click event only if the menu is Active
        // otherwise unsubscribe and save memory
        if(isActive === true){
          this._clickSub = this._utilitiesService.documentClickedTarget
           .subscribe(target => this._documentClickListener(target));
        }else if(isActive === false && this._clickSub !== null){
          this._clickSub.unsubscribe();
        }

      }),
      // other observable logic
      ...
      ).subscribe();
}

toggle() {
    this._toggleMenuSubject$.next(!this.isActive);
}

private _documentClickListener(targetElement: HTMLElement): void {
    const clickedInside = this._elementRef.nativeElement.contains(targetElement);
    if (!clickedInside) {
      this._toggleMenuSubject$.next(false);
    }    
 }

ngOnDestroy(){
 this._toggleMenuSub.unsubscribe();
}

And, in *.component.html:

<button (click)="toggle()">Toggle the menu</button>

For texts in angular template (userType is property of $scope, like $scope.userType):

<span>
  {{userType=='admin' ? 'Edit' : 'Show'}}
</span>

This may be a bit of a hack, but you can cast the .DayOfWeek property to an int (it's an enum and since its not had its underlying data type changed it defaults to int) and use that to determine the previous start of the week.

It appears the week specified in the DayOfWeek enum starts on Sunday, so if we subtract 1 from this value that'll be equal to how many days the Monday is before the current date. We also need to map the Sunday (0) to equal 7 so given 1 - 7 = -6 the Sunday will map to the previous Monday:-

DateTime now = DateTime.Now;
int dayOfWeek = (int)now.DayOfWeek;
dayOfWeek = dayOfWeek == 0 ? 7 : dayOfWeek;
DateTime startOfWeek = now.AddDays(1 - (int)now.DayOfWeek);

The code for the previous Sunday is simpler as we don't have to make this adjustment:-

DateTime now = DateTime.Now;
int dayOfWeek = (int)now.DayOfWeek;
DateTime startOfWeek = now.AddDays(-(int)now.DayOfWeek);

I'm not familiar with ASP.NET but I guess you could use a split function to split it in an array using the / as delimiter, then grab the last element in the array (usually the array length -1) to get the extract you want.

Ok this does not seem to work for all the examples.

What about a regex?

.*(/|[a-zA-Z]+\?)(.*)

then get that last subexpression (.*), I believe it's $+ in .Net, I'm not sure

As odd as it sound when you want to permit nested attributes you do specify the attributes of nested object within an array. In your case it would be

Update as suggested by @RafaelOliveira

params.require(:measurement)
      .permit(:name, :groundtruth => [:type, :coordinates => []])

On the other hand if you want nested of multiple objects then you wrap it inside a hash… like this

params.require(:foo).permit(:bar, {:baz => [:x, :y]})

Rails actually have pretty good documentation on this: http://api.rubyonrails.org/classes/ActionController/Parameters.html#method-i-permit

For further clarification, you could look at the implementation of permit and strong_parameters itself: https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/metal/strong_parameters.rb#L246-L247

I had been having the same issues, And during my tests, I have faced both problems:

1º: "File not found"

and

2º: 404 Error page

And I found out that, in my case:

I had to mount volumes for my public folders both on the Nginx volumes and the PHP volumes.

If it's mounted in Nginx and is not mounted in PHP, it will give: "File not found"

Examples (Will show "File not found error"):

services:
  php-fpm:
    build:
      context: ./docker/php-fpm
  nginx:
    build:
      context: ./docker/nginx
    volumes:
        #Nginx Global Configurations
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/conf.d/:/etc/nginx/conf.d

        #Nginx Configurations for you Sites:

        # - Nginx Server block
      - ./sites/example.com/site.conf:/etc/nginx/sites-available/example.com.conf
        # - Copy Public Folder:
      - ./sites/example.com/root/public/:/var/www/example.com/public
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php-fpm
    restart: always

If it's mounted in PHP and is not mounted in Nginx, it will give a 404 Page Not Found error.

Example (Will throw 404 Page Not Found Error):

version: '3'

services:
  php-fpm:
    build:
      context: ./docker/php-fpm
    volumes:
      - ./sites/example.com/root/public/:/var/www/example.com/public
  nginx:
    build:
      context: ./docker/nginx
    volumes:
        #Nginx Global Configurations
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/conf.d/:/etc/nginx/conf.d

        #Nginx Configurations for you Sites:

        # - Nginx Server block
      - ./sites/example.com/site.conf:/etc/nginx/sites-available/example.com.conf
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php-fpm
    restart: always

And this would work just fine (mounting on both sides) (Assuming everything else is well configured and you're facing the same problem as me):

version: '3'

services:
  php-fpm:
    build:
      context: ./docker/php-fpm
    volumes:
      # Mount PHP for Public Folder
      - ./sites/example.com/root/public/:/var/www/example.com/public
  nginx:
    build:
      context: ./docker/nginx
    volumes:
        #Nginx Global Configurations
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/conf.d/:/etc/nginx/conf.d

        #Nginx Configurations for you Sites:

        # - Nginx Server block
      - ./sites/example.com/site.conf:/etc/nginx/sites-available/example.com.conf
        # - Copy Public Folder:
      - ./sites/example.com/root/public/:/var/www/example.com/public
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php-fpm
    restart: always

Also here's a Full working example project using Nginx/Php, for serving multiple sites: https://github.com/Pablo-Camara/simple-multi-site-docker-compose-nginx-alpine-php-fpm-alpine-https-ssl-certificates

I hope this helps someone, And if anyone knows more about this please let me know, Thanks!

Null OR an empty string?

if (!empty($user)) {}

Use empty().

After realizing that $user ~= $_POST['user'] (thanks matt):

var uservariable='<?php 
    echo ((array_key_exists('user',$_POST)) || (!empty($_POST['user']))) ? $_POST['user'] : 'Empty Username Input';
?>';

Try this:

SELECT
    'the sqlserver is ' + substring(@@VERSION, 21, 5) AS [sql version]

AllDogs.First(d => d.Id == "2").Name = "some value";

However, a safer version of that might be this:

var dog = AllDogs.FirstOrDefault(d => d.Id == "2");
if (dog != null) { dog.Name = "some value"; }

This error will happen too even if the FormsModule is imported directly or indirectly (from a shared module for example) in the feature module, if the imported component is not declared on declarations:

I followed Deborah Kurata's Angular Routing course. While I added the imported component ProductEditInfoComponent on Angular Route's component property, I forgot to add ProductEditInfoComponent on declarations property.

Adding the ProductEditInfoComponent on the declarations property would solve the NG8002: Can't bind to 'ngModel' since it isn't a known property of 'input'. problem:

Just try

git remote add origin <HTTP URL>

To ignore some folder from eslint rules we could create the file .eslintignore in root directory and add there the path to the folder we want omit (the same way as for .gitignore).

Here is the example from the ESLint docs on Ignoring Files and Directories:

# path/to/project/root/.eslintignore
# /node_modules/* and /bower_components/* in the project root are ignored by default

# Ignore built files except build/index.js
build/*
!build/index.js

It is so simple:

Example URL:

http://stackoverflow.com:3000/activate_accountid=3&activatekey=$2a$08$jvGevXUOvYxKsiBt.PpMs.zgzD4C/wwTsvjzfUrqLrgS3zXJVfVRK

You can print all the values of query string by using:

console.log("All query strings: " + JSON.stringify(req.query));

Output

All query strings : { "id":"3","activatekey":"$2a$08$jvGevXUOvYxKsiBt.PpMs.zgzD4C/wwTsvjz fUrqLrgS3zXJVfVRK"}

To print specific:

console.log("activatekey: " + req.query.activatekey);

Output

activatekey: $2a$08$jvGevXUOvYxKsiBt.PpMs.zgzD4C/wwTsvjzfUrqLrgS3zXJVfVRK

I'm using MAMP (downloaded today) and had this problem also. The issue is with this version of the MAMP stack's default httpd.conf directive around line 370. Look at httpd.conf down at around line 370 and you will find:

<Directory "/Applications/MAMP/bin/mamp">
    Options Indexes MultiViews
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

You need to change: AllowOverride None To: AllowOverride All

I am posting a way to use _netrc to download materials from the site www.course.com.

If someone is going to use the coursera-dl to download the open-class materials on www.coursera.com, and on the Windows OS someone wants to use a file like ".netrc" which is in like-Unix OS to add the option -n instead of -U <username> -P <password> for convenience. He/she can do it like this:

1. Check the home path on Windows OS: setx HOME %USERPROFILE%(refer to VonC's answer). It will save the HOME environment variable as C:\Users\"username".

2. Locate into the directory C:\Users\"username" and create a file name _netrc.NOTE: there is NOT any suffix. the content is like: machine coursera-dl login <user> password <pass>

3. Use a command like coursera-dl -n --path PATH <course name> to download the class materials. More coursera-dl options details for this page.

Try setting startDate to the current date. For example:

$('.date-pick').datePicker({startDate:'01/01/1996'});

The accepted answer (its image) is wrong, at least now in QT5. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow instead of centralWidget). Also note that you must have at least one QObject created beneath it for this to work. Do this and your ui will become responsive to window resizing.

    int  pos  = 0;
    yourSeekBar.setMax(mPlayer.getDuration());

After You start Your MediaPlayer i.e mplayer.start()

Try this code

while(mPlayer!=null){
         try {
                Thread.sleep(1000);
                pos  = mPlayer.getCurrentPosition();
            }  catch (Exception e) {
                //show exception in LogCat
            }
            yourSeekBar.setProgress(pos);

   }

Before you added this code you have to create xml resource for SeekBar and use it in Your Activity class of ur onCreate() method.

See the problem is with the extension. Depending upon the extension, spring could figure out the content-type. If your url ends with .com then it sends text/html as the content-type header. If you want to change this behavior of Spring, please use the below code:

@Configuration
@Import(HibernateConfig.class)
@EnableWebMvc
// @EnableAsync()
// @EnableAspectJAutoProxy
@ComponentScan(basePackages = "com.azim.web.service.*",  basePackageClasses = { WebSecurityConfig.class }, excludeFilters = { @ComponentScan.Filter(Configuration.class) })
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        configurer.favorPathExtension(false).favorParameter(true).parameterName("mediaType").ignoreAcceptHeader(true).useJaf(false)
                .defaultContentType(MediaType.APPLICATION_JSON).mediaType("xml", MediaType.APPLICATION_XML).mediaType("json", MediaType.APPLICATION_JSON);
    }

    @Bean(name = "validator")
    public Validator validator() {
        return new LocalValidatorFactoryBean();
    }
}

Here, we are setting favorPathExtension to false and Default Content-type to Application/json. Note: HibernateConfig class contains all the beans.

It seems like you need to use __init__ in Python if you want to correctly initialize mutable attributes of your instances.

See the following example:

>>> class EvilTest(object):
...     attr = []
... 
>>> evil_test1 = EvilTest()
>>> evil_test2 = EvilTest()
>>> evil_test1.attr.append('strange')
>>> 
>>> print "This is evil:", evil_test1.attr, evil_test2.attr
This is evil: ['strange'] ['strange']
>>> 
>>> 
>>> class GoodTest(object):
...     def __init__(self):
...         self.attr = []
... 
>>> good_test1 = GoodTest()
>>> good_test2 = GoodTest()
>>> good_test1.attr.append('strange')
>>> 
>>> print "This is good:", good_test1.attr, good_test2.attr
This is good: ['strange'] []

This is quite different in Java where each attribute is automatically initialized with a new value:

import java.util.ArrayList;
import java.lang.String;

class SimpleTest
{
    public ArrayList<String> attr = new ArrayList<String>();
}

class Main
{
    public static void main(String [] args)
    {
        SimpleTest t1 = new SimpleTest();
        SimpleTest t2 = new SimpleTest();

        t1.attr.add("strange");

        System.out.println(t1.attr + " " + t2.attr);
    }
}

produces an output we intuitively expect:

[strange] []

But if you declare attr as static, it will act like Python:

[strange] [strange]

You must write onActivityResult() in your FirstActivity.Java as follows

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    for (Fragment fragment : getSupportFragmentManager().getFragments()) {
        fragment.onActivityResult(requestCode, resultCode, data);
    }
}

This will trigger onActivityResult method of fragments on FirstActivity.java

just adding the dependency of Lombok is not enough. You'll have to install the plugin of Lombok too.

You can get your Lombok jar file in by navigating through (Only if you have added the dependency in any of the POM.)

m2\repository\org\projectlombok\lombok\1.18.12\lombok-1.18.12

Also, if Lombok could not find the IDE, manually specify the .exe of your IDE and click install.

Restart your IDE.

That's it.

If you face any problem,

Below is a beautiful and short video about how to install the plugin of Lombok.

Just to save your time, you can start from 1:40.

https://www.youtube.com/watch?v=5K6NNX-GGDI

If it still doesn't work,

Verify that lombok.jar is there in your sts.ini file (sts config file, present in sts folder.)

-javaagent:lombok.jar

Do an Alt+F5. This will update your maven.

Close your IDE and again start it.

Imagine you have have a Book model and a Page model,

1:N means:
One book can have **many** pages. One page can only be in **one** book.


N:N means:
One book can have **many** pages. And one page can be in **many** books.

In Swift 4.2

let redView = UIView()
redView.backgroundColor = .red

let blueView = UIView()
blueView.backgroundColor = .blue

let stackView = UIStackView(arrangedSubviews: [redView, blueView])
stackView.axis = .vertical
stackView.distribution = .fillEqually

view.addSubview(stackView)

// stackView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)

// autolayout constraint
stackView.translatesAutoresizingMaskIntoConstraints = false

NSLayoutConstraint.activate([
    stackView.topAnchor.constraint(equalTo: view.topAnchor),
    stackView.leftAnchor.constraint(equalTo: view.leftAnchor),
    stackView.rightAnchor.constraint(equalTo: view.rightAnchor),
    stackView.heightAnchor.constraint(equalToConstant: 200)
])

General Solution

We use object-scan for a lot of data processing. It has some nice properties, especially traversing in delete safe order. Here is how one could implement find, delete and replace for your question.

// const objectScan = require('object-scan');

const tool = (() => {
  const scanner = objectScan(['[*]'], {
    abort: true,
    rtn: 'bool',
    filterFn: ({
      value, parent, property, context
    }) => {
      if (value.id === context.id) {
        context.fn({ value, parent, property });
        return true;
      }
      return false;
    }
  });
  return {
    add: (data, id, obj) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property + 1, 0, obj) }),
    del: (data, id) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property, 1) }),
    mod: (data, id, prop, v = undefined) => scanner(data, {
      id,
      fn: ({ value }) => {
        if (value !== undefined) {
          value[prop] = v;
        } else {
          delete value[prop];
        }
      }
    })
  };
})();

// -------------------------------

const data = [ { id: 'one', pId: 'foo1', cId: 'bar1' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ];
const toAdd = { id: 'two', pId: 'foo2', cId: 'bar2' };

const exec = (fn) => {
  console.log('---------------');
  console.log(fn.toString());
  console.log(fn());
  console.log(data);
};

exec(() => tool.add(data, 'one', toAdd));
exec(() => tool.mod(data, 'one', 'pId', 'zzz'));
exec(() => tool.mod(data, 'one', 'other', 'test'));
exec(() => tool.mod(data, 'one', 'gone', 'delete me'));
exec(() => tool.mod(data, 'one', 'gone'));
exec(() => tool.del(data, 'three'));

// => ---------------
// => () => tool.add(data, 'one', toAdd)
// => true
// => [ { id: 'one', pId: 'foo1', cId: 'bar1' }, { id: 'two', pId: 'foo2', cId: 'bar2' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ]
// => ---------------
