For those who are still getting blank response with $request->getContent(), you can use:

$request->all()

e.g:

public function foo(Request $request){
   $bodyContent = $request->all();
}

Personally I like it this way:

DateTime.Now.ToString("yyyy-MM-dd HH.mm.ss")

Because it distinguishes between the date and the time.

use the pair long t = now.Ticks and DateTime Today = new DateTime(t)

unlink('path_to_filename'); will delete one file at a time.

If your whole files from directory is gone means you listed all files and deleted one by one in a loop.

Well you cannot de delete in the same page. You have to do with other page. create a page called deletepage.php which will contain script to delete and link to that page with 'file' as parameter.

foreach($FilesArray as $file)
{
    $FileLink = $Directory.'/'.$file['FileName'];

    if($OpenFileInNewTab) $LinkTarget = ' target="_blank"'; 
    else $LinkTarget = '';

    echo '<a href="'.$FileLink.'">'.$FileName.'</a>';
    echo '<a href="deletepage.php?file='.$fileName.'"><img src="images/icons/delete.gif"></a></td>';        
}

On the deletepage.php

//and also consider to check if the file exists as with the other guy suggested.
$filename = $_GET['file']; //get the filename
unlink('DIRNAME'.DIRECTORY_SEPARATOR.$filename); //delete it
header('location: backto prev'); //redirect back to the other page

If you don't want to navigate, then use ajax to make elegant.

With SQL Server you'd SELECT SCOPE_IDENTITY() to get the last identity value for the current process.

With SQlite, it looks like for an autoincrement you would do

SELECT last_insert_rowid()

immediately after your insert.

http://www.mail-archive.com/[email protected]/msg09429.html

In answer to your comment to get this value you would want to use SQL or OleDb code like:

using (SqlConnection conn = new SqlConnection(connString))
{
    string sql = "SELECT last_insert_rowid()";
    SqlCommand cmd = new SqlCommand(sql, conn);
    conn.Open();
    int lastID = (Int32) cmd.ExecuteScalar();
}

Great solution but for my Windows I need make a modifications. Below the modify code

function Zip($source, $destination){

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
    return false;
}

$source = str_replace('\\', '/', realpath($source));

if (is_dir($source) === true)
{
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    foreach ($files as $file)
    {
        $file = str_replace('\\', '/', $file);

        // Ignore "." and ".." folders
        if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
            continue;

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(str_replace($source . '/', '', $file));
        }
        else if (is_file($file) === true)
        {

            $str1 = str_replace($source . '/', '', '/'.$file);
            $zip->addFromString($str1, file_get_contents($file));

        }
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));
}

return $zip->close();
}

In bash, contrary to [, [[ prevents word splitting of variable values.

Installing through distributed JDK DMG from the Oracle site auto-updates everything for me. I have seen (in El Capitan) updating through System Preferences > Java do updates but that do not reflect to command line. Installing through DMG does the job.

If someone wants to transfer file from windows host to vagrant, then this solution worked for me.

1. Make sure to install **winscp** on your windows system
2. run **vagrant up** command
3. run **vagrant ssh-config** command and note down below details
4. Enter Hostname, Port, Username: vagrant, Password: vagrant in winscp and select **SCP**, file protocol 
5. In most cases, hostname: 127.0.0.1, port: 2222, username: vagrant, password: vagrant.

You should be able to see directories in your vagrant machine.

I faced this issue on Node 10.X version. below is my working code.

const https = require('https');

exports.handler = (event,context,callback) => {
    let body='';
    let jsonObject = JSON.stringify(event);

    // the post options
    var optionspost = {
      host: 'example.com', 
      path: '/api/mypath',
      method: 'POST',
      headers: {
      'Content-Type': 'application/json',
      'Authorization': 'blah blah',
    }
    };

    let reqPost =  https.request(optionspost, function(res) {
        console.log("statusCode: ", res.statusCode);
        res.on('data', function (chunk) {
            body += chunk;
        });
        res.on('end', function () {
           console.log("Result", body.toString());
           context.succeed("Sucess")
        });
        res.on('error', function () {
          console.log("Result Error", body.toString());
          context.done(null, 'FAILURE');
        });
    });
    reqPost.write(jsonObject);
    reqPost.end();
};

you have to add the missing local lang helper: for me the missing ones where de_LU de_LU.UTF-8 . Mongo 2.6.4 worked wihtout mongo 2.6.5 throw an error on this

Here's a a couple of useful link that I found when I started with JNI

http://en.wikipedia.org/wiki/Java_Native_Interface
http://download.oracle.com/javase/1.5.0/docs/guide/jni/spec/functions.html

concerning your problem you can use this

JNIEXPORT void JNICALL Java_ClassName_MethodName(JNIEnv *env, jobject obj, jstring javaString)   
{
   const char *nativeString = env->GetStringUTFChars(javaString, 0);

   // use your string

   env->ReleaseStringUTFChars(javaString, nativeString);
}

It is not allocating memory at assignment of value 12 to integer pointer. Therefore it crashes, because it's not finding any memory.

You can try this:

#include<stdio.h>
#include<stdlib.h>
int *fun();

int main()
{
    int *ptr;
    ptr=fun();
    printf("\n\t\t%d\n",*ptr);
}

int *fun()
{
    int ptr;
    ptr=12;
    return(&ptr);
}

This is the classroom problem called 'Longest sequence finder'. I have given some simple code that worked for me, also my inputs are lists of a sequence which can also be a string:

def longest_substring(list1,list2):
    both=[]
    if len(list1)>len(list2):
        small=list2
        big=list1
    else:
        small=list1
        big=list2
    removes=0
    stop=0
    for i in small:
        for j in big:
            if i!=j:
                removes+=1
                if stop==1:
                    break
            elif i==j:
                both.append(i)
                for q in range(removes+1):
                    big.pop(0)
                stop=1
                break
        removes=0
    return both

I think this site has the solution, i will test it now. It Seems like facebook has changed the parameters of share.php so, in order to customize share window text and images you have to put parameters in a "p" array.

Some sargable methods...

SELECT *
FROM #T
WHERE SomeCol = '' OR SomeCol IS NULL;

SELECT *
FROM #T
WHERE SomeCol = '' 
UNION ALL
SELECT *
FROM #T
WHERE  SomeCol IS NULL;

SELECT *
FROM #T
WHERE EXISTS ((SELECT NULL UNION SELECT '') INTERSECT SELECT SomeCol);

And some non-sargable ones...

SELECT *
FROM #T
WHERE IIF(SomeCol <> '',0,1) = 1;

SELECT *
FROM #T
WHERE NULLIF(SomeCol,'') IS NULL;

SELECT *
FROM #T
WHERE ISNULL(SomeCol,'') = '';

Just document it here on Windows you need to escape the \ character:

"e:\\directory\\-"

If you use native sql, you can refer to my code, otherwise just ignore my answer.

SELECT * FROM table WHERE tags LIKE "%banana%";

from sqlalchemy import text

bar_tags = "banana"

# '%' attention to spaces
query_sql = """SELECT * FROM table WHERE tags LIKE '%' :bar_tags '%'"""

# db is sqlalchemy session object
tags_res_list = db.execute(text(query_sql), {"bar_tags": bar_tags}).fetchall()

I was reading path from a properties file and didn't mention there was a space in the end. Make sure you don't have one.

using System;
using System.Threading;
using System.Threading.Tasks;

...

var cts = new CancellationTokenSource();
var task = Task.Run(() => { while (true) { } });
Parallel.Invoke(() =>
{
    task.Wait(cts.Token);
}, () =>
{
    Thread.Sleep(1000);
    cts.Cancel();
});

This is a simple snippet to abort a never-ending task with CancellationTokenSource.

Maybe useful for anyone else running into this issue: When setting the port on the properties:

props.put("mail.smtp.port", smtpPort);

..make sure to use a string object. Using a numeric (ie Long) object will cause this statement to seemingly have no effect.

When the servlet container (like Apache Tomcat) starts up, it will read from the web.xml file (only one per application) if anything goes wrong or shows up an error at container side console, otherwise, it will deploy and load all web applications by using web.xml (so named it as deployment descriptor).

During instantiation phase of the servlet, servlet instance is ready but it cannot serve the client request because it is missing with two pieces of information:
1: context information
2: initial configuration information

Servlet engine creates servletConfig interface object encapsulating the above missing information into it servlet engine calls init() of the servlet by supplying servletConfig object references as an argument. Once init() is completely executed servlet is ready to serve the client request.

Q) In the lifetime of servlet how many times instantiation and initialization happens ??

A)only once (for every client request a new thread is created) only one instance of the servlet serves any number of the client request ie, after serving one client request server does not die. It waits for other client requests ie what CGI (for every client request a new process is created) limitation is overcome with the servlet (internally servlet engine creates the thread).

Q)How session concept works?

A)whenever getSession() is called on HttpServletRequest object

Step 1: request object is evaluated for incoming session ID.

Step 2: if ID not available a brand new HttpSession object is created and its corresponding session ID is generated (ie of HashTable) session ID is stored into httpservlet response object and the reference of HttpSession object is returned to the servlet (doGet/doPost).

Step 3: if ID available brand new session object is not created session ID is picked up from the request object search is made in the collection of sessions by using session ID as the key.

Once the search is successful session ID is stored into HttpServletResponse and the existing session object references are returned to the doGet() or doPost() of UserDefineservlet.

Note:

1)when control leaves from servlet code to client don't forget that session object is being held by servlet container ie, the servlet engine

2)multithreading is left to servlet developers people for implementing ie., handle the multiple requests of client nothing to bother about multithread code

Inshort form:

A servlet is created when the application starts (it is deployed on the servlet container) or when it is first accessed (depending on the load-on-startup setting) when the servlet is instantiated, the init() method of the servlet is called then the servlet (its one and only instance) handles all requests (its service() method being called by multiple threads). That's why it is not advisable to have any synchronization in it, and you should avoid instance variables of the servlet when the application is undeployed (the servlet container stops), the destroy() method is called.

If there are are no duplicate elements or you don't care about them, then you can use the Set class:

a1 = Set.new [5, 1, 6, 14, 2, 8]
a2 = Set.new [2, 6, 15]
a1.subset?(a2)
=> false

Behind the scenes this uses

all? { |o| set.include?(o) }

You can use %p in C

In C:

printf("%p",p)

In C++:

cout<<"Address of pointer p is: "<<p

You can use any of the following:

\b      #A word break and will work for both spaces and end of lines.
(^|\s)  #the | means or. () is a capturing group. 


/\b(stackoverflow)\b/

Also, if you don't want to include the space in your match, you can use lookbehind/aheads.

(?<=\s|^)         #to look behind the match
(stackoverflow)   #the string you want. () optional
(?=\s|$)          #to look ahead.

you can simply write $('span#a').length to get the length.

Here is the Solution for your code:

console.log($('span#a').length);

try JSfiddle: https://jsfiddle.net/vickyfor2007/wcc0ab5g/2/

You can use StringBuffer or StringBuilder for this. Both are for dynamic string manipulation. StringBuffer is thread-safe where as StringBuilder is not.

Use StringBuffer in a multi-thread environment. But if it is single threaded StringBuilder is recommended and it is much faster than StringBuffer.

Adding to what b_levitt said, you can get the SSDT-BI plugin for Visual Studio 2013 here: http://www.microsoft.com/en-us/download/details.aspx?id=42313

I know the question is rather old but I believe this issue is still present.

Viewing databases from your browser

I created a development tool that you can integrate as a lib into your android app project. The tool opens a server socket in your app to communicate via web browser. You can browse through your whole database and download the database file directly through the browser.

Integration can be done via jitpack.io:

project build.gradle:

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

app build.gradle:

//...
dependencies {
    //...
    debugCompile 'com.github.sanidgmbh:debugghost:v1.1'
    //...
}
//...

Setup Application class

In order to only compile DebugGhostLib in certain build-types or product-flavours we need an abstract Application class which will be derived in the special flavours. Put the following class in your main folder (under java > your.app.package):

public class AbstractDebugGhostExampleApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        // Do your general application stuff
    }
}

Now, for your release build type (or product flavour), you add the following Application class to your release (or product-flavour) folder (also under java > your.app.package):

public class MyApp extends AbstractDebugGhostExampleApplication {
    @Override
    public void onCreate() {
        super.onCreate();
    }
}

This is the application class that will not reference DebugGhostLib.

Also tell your AndroidManifest.xml that you're using your own application class. This will be done in your main folder:

<manifest package="demo.app.android.sanid.com.debugghostexample" xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- permissions go here -->
    <application android:name=".MyApp"> <!-- register your own application class -->
        <!-- your activities go here -->
    </application>
</manifest>

Now, for your debug build type (or product flavour), you add the following Application class to your debug (or product-flavour) folder (also under java > your.app.package):

public class MyApp extends AbstractDebugGhostExampleApplication {
    private DebugGhostBridge mDebugGhostBridge;

    @Override
    public void onCreate() {
        super.onCreate();

        mDebugGhostBridge = new DebugGhostBridge(this, MyDatabaseHelper.DATABASE_NAME, MyDatabaseHelper.DATABASE_VERSION);
        mDebugGhostBridge.startDebugGhost();
    }
}

You can get the tool here.

It depends on your default version of python setup. You can query by Python Version:

python3 --version //to check which version of python3 is installed on your computer
python2 --version // to check which version of python2 is installed on your computer
python --version // it shows your default Python installed version.

Ok, here is a safe way of doing it.

with open('example.txt', 'w') as f:
 for i in range(10):
  f.write(str(i+1))
  f.write('\n')

This writes 1 to 10 each number on a new line.

This is a crappy technique, but it's pretty much guaranteed:

<img onerror="this.parentNode.removeChild(this);">

There is a library named Picasso which can efficiently load images from a URL. It can also load an image from a file.

Examples:

1. Load URL into ImageView without generating a bitmap:

   Picasso.with(context) // Context
          .load("http://abc.imgur.com/gxsg.png") // URL or file
          .into(imageView); // An ImageView object to show the loaded image
   

2. Load URL into ImageView by generating a bitmap:

   Picasso.with(this)
          .load(artistImageUrl)
          .into(new Target() {
              @Override
              public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
                  /* Save the bitmap or do something with it here */
   
                  // Set it in the ImageView
                  theView.setImageBitmap(bitmap)
              }
   
              @Override
              public void onBitmapFailed(Drawable errorDrawable) {
   
              }
   
              @Override
              public void onPrepareLoad(Drawable placeHolderDrawable) {
   
              }
          });
   

There are many more options available in Picasso. Here is the documentation.

This is the best way for me:

cat filename.tsv  |
    while read FILENAME
    do
    sudo find /PATH_FROM/  -name "$FILENAME" -maxdepth 4 -exec cp '{}' /PATH_TO/ \; ;
    done

you can do this too with animation, its very simple

$('html, body').animate({
   scrollTop: $('footer').offset().top
   //scrollTop: $('#your-id').offset().top
   //scrollTop: $('.your-class').offset().top
}, 'slow');

hope helps, thank you

The issue is fixed by adding repository url under distributionManagement tab in main pom.xml.

Jenkin maven goal : clean deploy -U -Dmaven.test.skip=true

    </repository>
    <snapshotRepository>

To get the current time in UTC in Python 3.2+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).isoformat()
'2015-01-27T05:57:31.399861+00:00'

To get local time in Python 3.3+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).astimezone().isoformat()
'2015-01-27T06:59:17.125448+01:00'

Explanation: datetime.now(timezone.utc) produces a timezone aware datetime object in UTC time. astimezone() then changes the timezone of the datetime object, to the system's locale timezone if called with no arguments. Timezone aware datetime objects then produce the correct ISO format automatically.

In Swift 4 tableview add, swipe to delete UITableViewCell

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .destructive, title: "delete") { (action, indexPath) in
        // delete item at indexPath

    }
    return [delete]
}

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.

NB - You need to do this first on a test copy of your table!

When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.

1. If you want to keep the row with the lowest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
   

2. If you want to keep the row with the highest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
   

I used this method in MySQL 5.1

Not sure about other versions.

Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.

INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
    SELECT DISTINCT cellId,attributeId,entityRowId,value
    FROM tableName;

Try using the type attribute selector to find buttons (maybe this'll fix it too):

input[type=button]
{
  background-color: #E3E1B8; 
}

input[type=button]:hover
{
  background-color: #46000D
}

here a quick script to test if a shell script is running

#!/bin/sh

scripToTest="your_script_here.sh"
scriptExist=$(pgrep -f "$scripToTest")
[ -z "$scriptExist" ] && echo "$scripToTest : not running" || echo "$scripToTest : runnning"

Big O is the upper bound, while Omega is the lower bound. Theta requires both Big O and Omega, so that's why it's referred to as a tight bound (it must be both the upper and lower bound).

For example, an algorithm taking Omega(n log n) takes at least n log n time, but has no upper limit. An algorithm taking Theta(n log n) is far preferential since it takes at least n log n (Omega n log n) and no more than n log n (Big O n log n).

Parameter Options FollowSymLinks enables you to have a symlink in your webroot pointing to some other file/dir. With this disabled, Apache will refuse to follow such symlink. More secure Options SymLinksIfOwnerMatch can be used instead - this will allow you to link only to other files which you do own.

If you use Options directive in .htaccess with parameter which has been forbidden in main Apache config, server will return HTTP 500 error code.

Allowed .htaccess options are defined by directive AllowOverride in the main Apache config file. To allow symlinks, this directive need to be set to All or Options.

Besides allowing use of symlinks, this directive is also needed to enable mod_rewrite in .htaccess context. But for this, also the more secure SymLinksIfOwnerMatch option can be used.

My solution is to use Split and Join and it is surprisingly fast, in fact the fastest of the top answers here.

str = string.Join("", str.Split(default(string[]), StringSplitOptions.RemoveEmptyEntries));

Timings for 10,000 loop on simple string with whitespace inc new lines and tabs

• split/join = 60 milliseconds
• linq chararray = 94 milliseconds
• regex = 437 milliseconds

Improve this by wrapping it up in method to give it meaning, and also make it an extension method while we are at it ...

public static string RemoveWhitespace(this string str) {
    return string.Join("", str.Split(default(string[]), StringSplitOptions.RemoveEmptyEntries));
}

Try this, it worked for me on Google Chrome:

<style media="print" type="text/css">
    .page {
        background-color: white !important;
    }
</style>

You can get every file, then filter the array:

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dirInfo, params string[] extensions)
{
    var allowedExtensions = new HashSet<string>(extensions, StringComparer.OrdinalIgnoreCase);

    return dirInfo.EnumerateFiles()
                  .Where(f => allowedExtensions.Contains(f.Extension));
}

This will be (marginally) faster than every other answer here.
In .Net 3.5, replace EnumerateFiles with GetFiles (which is slower).

And use it like this:

var files = new DirectoryInfo(...).GetFilesByExtensions(".jpg", ".mov", ".gif", ".mp4");

If you can supply a default value for your selects, then you can use the same approach for unchecked check boxes which requires a hidden input before the actual element, as these don't post a value if left unchecked:

<input type="hidden" name="myfield" value="default" />
<select name="myfield">
    <option value="default" selected="selected">Default</option>
    <option value="othervalue">Other value</option>
    <!-- ... //-->
</select>

This will actually post the value "default" (without quotes, obviously) if the select is disabled by javascript (or jQuery) or even if your code writes the html disabling the element itself with the attribute: disabled="disabled".

hashMaps can't have duplicate keys. That said, you can create a map with list values:

Map<Integer, List<String>>

However, using this approach will have performance implications.

For some reason Andrew method of creating the checkbox by hand didn't work for me using Mvc 5. Instead I used this

@Html.CheckBox("checkResp")

to create a checkbox that would play nice with the controller.

So I had a similar issue where I had a bean with some overloaded constructor. This bean also had Optional properties.

To resolve that I just removed the overloaded constructors and it worked.

example:

public class Bean{

Optional<String> string;
Optional<AnotherClass> object;

public Bean(Optional<String> str, Optional<AnotherClass> obj){
string = str;
object = obj;
}

///The problem was below constructor

public Bean(Optional<String> str){
string = str;
object = Optional.empty();
}



}

}

If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:

curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Doing this you'll force to use es without replicas

    myButton.frame = CGRectMake(15, 50, 300, 500)
    myButton.addTarget(self, action: "pressedAction:", forControlEvents: .TouchUpInside)

    self.view.addSubview( myButton)


func pressedAction(sender: UIButton!) {
   // do your stuff here 
  NSLog("you clicked on button %@", sender.tag)

    myButton.setTitle("Hi, Click me", for: .normal)
    myButton.setTitleColor(UIColor.blue, for: .normal)

A hook is functionality provided by software for users of that software to have their own code called under certain circumstances. That code can augment or replace the current code.

In the olden days when computers were truly personal and viruses were less prevalent (I'm talking the '80's), it was as simple as patching the operating system software itself to call your code. I remember writing an extension to the Applesoft BASIC language on the Apple II which simply hooked my code into the BASIC interpreter by injecting a call to my code before any of the line was processed.

Some computers had pre-designed hooks, one example being the I/O stream on the Apple II. It used such a hook to inject the whole disk sub-system (Apple II ROMs were originally built in the days where cassettes were the primary storage medium for PCs). You controlled the disks by printing the ASCII code 4 (CTRL-D) followed by the command you wanted to execute then a CR, and it was intercepted by the disk sub-system, which had hooked itself into the Apple ROM print routines.

So for example, the lines:

PRINT CHR(4);"CATALOG"
PRINT CHR(4);"IN#6"

would list the disk contents then re-initialize the machine. This allowed such tricks as protecting your BASIC programs by setting the first line as:

123 REM XIN#6

then using POKE to insert the CTRL-D character in where the X was. Then, anyone trying to list your source would send the re-initialize sequence through the output routines where the disk sub-system would detect it.

That's often the sort of trickery we had to resort to, to get the behavior we wanted.

Nowadays, with the operating system more secure, it provides facilities for hooks itself, since you're no longer supposed to modify the operating system "in-flight" or on the disk.

They've been around for a long time. Mainframes had them (called exits) and a great deal of mainframe software uses those facilities even now. For example, the free source code control system that comes with z/OS (called SCLM) allows you to entirely replace the security subsystem by simply placing your own code in the exit.

Use splatting.

$CurlArgument = '-u', '[email protected]:yyyy',

Here is my use case, which requires an exceptional amount of encoding. Maybe you think it contrived, but we run this on production. Coincidently, this covers every type of encoding, so I'm posting as a tutorial.

Use case description

Somebody just bought a prepaid gift card ("token") on our website. Tokens have corresponding URLs to redeem them. This customer wants to email the URL to someone else. Our web page includes a mailto link that lets them do that.

PHP code

// The order system generates some opaque token
$token = 'w%a&!e#"^2(^@azW';

// Here is a URL to redeem that token
$redeemUrl = 'https://httpbin.org/get?token=' . urlencode($token);

// Actual contents we want for the email
$subject = 'I just bought this for you';
$body = 'Please enter your shipping details here: ' . $redeemUrl;

// A URI for the email as prescribed
$mailToUri = 'mailto:?subject=' . rawurlencode($subject) . '&body=' . rawurlencode($body);

// Print an HTML element with that mailto link
echo '<a href="' . htmlspecialchars($mailToUri) . '">Email your friend</a>';

Note: the above assumes you are outputting to a text/html document. If your output media type is text/json then simply use $retval['url'] = $mailToUri; because output encoding is handled by json_encode().

Test case

1. Run the code on a PHP test site (is there a canonical one I should mention here?)
2. Click the link
3. Send the email
4. Get the email
5. Click that link

You should see:

"args": {
  "token": "w%a&!e#\"^2(^@azW"
}, 

And of course this is the JSON representation of $token above.

While joshperry's answer is correct, I find very annoying that it does not tell you the screen name (the one you set with -t option), that is actually what you use to identify a session. (not his fault, of course, that's a screen's flaw)

That's why I instead use a script such as this: ps auxw|grep -i screen|grep -v grep

Use commons-io IOUtils.toByteArray(URL):

Always google so you can locate the latest package for both NPP and NPP Plugins.

I googled "notepad++ 64bit". Downloaded the free latest version at Notepad++ (64-bit) - Free download and software. Installed notepad++ by double-click on npp.?.?.?.Installer.x64.exe, installed the .exe to default Windows 64bit path which is, "C:\Program Files".

Then, I googled "notepad++ 64 json viewer plug". Knowing SourceForge.Net is a renowned download site, downloaded JSToolNpp [email protected]. I unzipped and copied JSMinNPP.dll to notePad++ root dir.

I loaded my newly installed notepad++ 64bit. I went to Settings and selected [import plug-in]. I pointed to the location of JSMinNPP.dll and clicked open.

I reloaded notepad++, went to PlugIns menu. To format one-line json string to multi-line json doc, I clicked JSTool->JSFormat or reverse multi-line json doc to one-line json string by JSTool->JSMin (json-Minified)!

An approach using extension methods:

class Program
{
    static void Main(string[] args)
    {
        DateTime t = DateTime.Now;

        DateTime p = t.PreviousMonthFirstDay();
        Console.WriteLine( p.ToShortDateString() );

        p = t.PreviousMonthLastDay();
        Console.WriteLine( p.ToShortDateString() );


        Console.ReadKey();
    }
}


public static class Helpers
{
    public static DateTime PreviousMonthFirstDay( this DateTime currentDate )
    {
        DateTime d = currentDate.PreviousMonthLastDay();

        return new DateTime( d.Year, d.Month, 1 );
    }

    public static DateTime PreviousMonthLastDay( this DateTime currentDate )
    {
        return new DateTime( currentDate.Year, currentDate.Month, 1 ).AddDays( -1 );
    }
}

See this link http://www.codeplex.com/fluentdatetime for some inspired DateTime extensions.

You can use .rstrip('\n') to only remove newlines from the end of the string:

for i in contents:
    alist.append(i.rstrip('\n'))

This leaves all other whitespace intact. If you don't care about whitespace at the start and end of your lines, then the big heavy hammer is called .strip().

However, since you are reading from a file and are pulling everything into memory anyway, better to use the str.splitlines() method; this splits one string on line separators and returns a list of lines without those separators; use this on the file.read() result and don't use file.readlines() at all:

alist = t.read().splitlines()

You need an scp client. Putty is not one. You can use WinSCP or PSCP. Both are free software.

In which way do you want it dynamic? If you want the popup to successfully map to the background, you need to create two backgrounds. It requires both the use of element() or -moz-element() and a filter (for Firefox, use a SVG filter like filter: url(#svgBlur) since Firefox does not support -moz-filter: blur() as yet?). It only works in Firefox at the time of writing.

See demo here.

I still need to create a simple demo to show how it is done. You're welcome to view the source.

Roman Samoylenko's answer was correct except the function has changed. The correct answer is

Glide.with(context)
                .load(yourImage)
                .apply(RequestOptions.circleCropTransform())
                .into(imageView);

Use this to get the page scroll position.

var screenTop = $(document).scrollTop();

$('#content').css('top', screenTop);

Figured I'd post a project I recently came across to get dominant color:

Color Thief

A script for grabbing the dominant color or a representative color palette from an image. Uses javascript and canvas.

The other solutions mentioning and suggesting dominant color never really answer the question in proper context ("in javascript"). Hopefully this project will help those who want to do just that.

You can try Gson convertor, to get the exact conversion like json.stringify

val jsonString:String = jsonObject.toString()
val gson:Gson = GsonBuilder().setPrettyPrinting().create()
val json:JsonElement = gson.fromJson(jsonString,JsonElement.class)
val jsonInString:String= gson.toJson(json)
println(jsonInString)

Java converts Integer to int and back automatically (unless you are still with Java 1.4).

let dateVar = moment('any date value');
let newDateVar = dateVar.utc().format();

nice and clean!!!!

i know it's old, but too tempting. so, the answer is: you can't... but you kind of can. let's try this:

$IMG_WIDTH=1024
$IMG2_WIDTH=2048

$RATIO="$(( IMG_WIDTH / $IMG2_WIDTH )).$(( (IMG_WIDTH * 100 / IMG2_WIDTH) % 100 ))

like that you get 2 digits after the point, truncated (call it rounding to the lower, haha) in pure bash (no need to launch other processes). of course, if you only need one digit after the point you multiply by 10 and do modulo 10.

what this does:

• first $((...)) does integer division;
• second $((...)) does integer division on something 100 times larger, essentially moving your 2 digits to the left of the point, then (%) getting you only those 2 digits by doing modulo.

bonus track: bc version x 1000 took 1,8 seconds on my laptop, while the pure bash one took 0,016 seconds.

I get the same problem. I have used 10hrs to findout.

https://serverless.com/framework/docs/providers/aws/events/apigateway/

// handler.js

'use strict';

module.exports.hello = function(event, context, callback) {

const response = {
  statusCode: 200,
  headers: {
    "Access-Control-Allow-Origin" : "*", // Required for CORS support to work
    "Access-Control-Allow-Credentials" : true // Required for cookies, authorization headers with HTTPS 
  },
  body: JSON.stringify({ "message": "Hello World!" })
};

callback(null, response);
};

Here is one solution (single user):

GOROOT=$HOME/.local # your go executable is in $GOROOT/bin
GOPATH=$HOME/.gopath
PATH=$GOROOT/bin:$GOPATH/bin:$PATH

go complains if you change .gopath to .go.

I wish they went with how the rust/cargo guys did and just put everything at one place.

use window.location.href = url

<html>
<head>
    <title>Disable Back Button in Browser - Online Demo</title>
    <style type="text/css">
        body, input {
            font-family: Calibri, Arial;
        }
    </style>
    <script type="text/javascript">
        window.history.forward();
        function noBack() {
            window.history.forward();
        }
    </script>
</head>
<body onload="noBack();" onpageshow="if (event.persisted) noBack();" onunload="">
    <H2>Demo</H2>
    <p>This page contains the code to avoid Back button.</p>
    <p>Click here to Goto <a href="noback.html">NoBack Page</a></p>
</body>
</html>

This will also work:

c = (count - 1) / 10 + 1;

Like this:

public Sample(string str) : this(int.Parse(str)) { }

This should give the list of devices available for Tensorflow (under Py-3.6):

tf = tf.Session(config=tf.ConfigProto(log_device_placement=True))
tf.list_devices()
# _DeviceAttributes(/job:localhost/replica:0/task:0/device:CPU:0, CPU, 268435456)

It's empty by default. You'll find a bunch of settings in /etc/apache2/apache2.conf.

In there it does this:

# Include all the user configurations:
Include httpd.conf

When in Node.js or when using require.js in the browser, you can simply do:

let json = require('/Users/Documents/workspace/test.json');
console.log(json, 'the json obj');

Do note: the file is loaded once, subsequent calls will use the cache.

using System.Windows.Forms;
...
MessageBox.Show("Hello World!");

Python may be good, but it isn't God...

There are a few different ways to solve equations. SymPy has already been mentioned, if you're looking for analytic solutions.

If you're happy to just have a numerical solution, Numpy has a few routines that can help. If you're just interested in solutions to polynomials, numpy.roots will work. Specifically for the case you mentioned:

>>> import numpy
>>> numpy.roots([2,-6])
array([3.0])

For more complicated expressions, have a look at scipy.fsolve.

Either way, you can't escape using a library.

In Python 3.8+ you can do

import hashlib

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

On Python 3.7 and below:

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    chunk = f.read(8192)
    while chunk:
        file_hash.update(chunk)
        chunk = f.read(8192)

print(file_hash.hexdigest())

This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read() to use less memory.

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippets). It's cryptographically secure and faster than MD5.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

getWindow is a method defined for activities, and won't require you to find a View first.

What you want is lazy iteration over an object or array. This is not possible in ES5 (thus not possible in node.js). We will get this eventually.

The only solution is finding a node module that extends V8 to implement iterators (and probably generators). I couldn't find any implementation. You can look at the spidermonkey source code and try writing it in C++ as a V8 extension.

You could try the following, however it will also load all the keys into memory

Object.keys(o).forEach(function(key) {
  var val = o[key];
  logic();
});

However since Object.keys is a native method it may allow for better optimisation.

Benchmark

As you can see Object.keys is significantly faster. Whether the actual memory storage is more optimum is a different matter.

var async = {};
async.forEach = function(o, cb) {
  var counter = 0,
    keys = Object.keys(o),
    len = keys.length;
  var next = function() {
    if (counter < len) cb(o[keys[counter++]], next);
  };
  next();
};

async.forEach(obj, function(val, next) {
  // do things
  setTimeout(next, 100);
});

Usual way is to go with PHP and ajax. But for your requirement, below will work fine.

I'm sorry to say this and maybe I'm not solving your problem exactly but PostgreSQL is 10 years older than MySQL and is extremely advanced compared to MySQL and there's many ways to achieve this easily. Install PostgreSQL and execute this query

CREATE EXTENSION tablefunc;

then voila! And here's extensive documentation: PostgreSQL: Documentation: 9.1: tablefunc or this query

CREATE EXTENSION hstore;

then again voila! PostgreSQL: Documentation: 9.0: hstore

Macmade's solution doesn't work for me anymore on my Jekyll instance on Github Pages anymore but I found this solution on an issue for the kramdown github repo. For OP's example it would look like this:

Solved my issues handily.

I know that this is an old question but I wanted to write my answer for visual learners. I couldn't find any diagrams explaining output buffering on the worldwide-web so I made a diagram myself in Windows mspaint.exe.

If output buffering is turned off, then echo will send data immediately to the Browser.

If output buffering is turned on, then an echo will send data to the output buffer before sending it to the Browser.

phpinfo

To see whether Output buffering is turned on / off please refer to phpinfo at the core section. The output_buffering directive will tell you if Output buffering is on/off.

In this case the output_buffering value is 4096 which means that the buffer size is 4 KB. It also means that Output buffering is turned on, on the Web server.

php.ini

It's possible to turn on/off and change buffer size by changing the value of the output_buffering directive. Just find it in php.ini, change it to the setting of your choice, and restart the Web server. You can find a sample of my php.ini below.

; Output buffering is a mechanism for controlling how much output data
; (excluding headers and cookies) PHP should keep internally before pushing that
; data to the client. If your application's output exceeds this setting, PHP
; will send that data in chunks of roughly the size you specify.
; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance
; reasons.
; Note: Output buffering can also be controlled via Output Buffering Control
;   functions.
; Possible Values:
;   On = Enabled and buffer is unlimited. (Use with caution)
;   Off = Disabled
;   Integer = Enables the buffer and sets its maximum size in bytes.
; Note: This directive is hardcoded to Off for the CLI SAPI
; Default Value: Off
; Development Value: 4096
; Production Value: 4096
; http://php.net/output-buffering
output_buffering = 4096

The directive output_buffering is not the only configurable directive regarding Output buffering. You can find other configurable Output buffering directives here: http://php.net/manual/en/outcontrol.configuration.php

Example: ob_get_clean()

Below you can see how to capture an echo and manipulate it before sending it to the browser.

// Turn on output buffering  
ob_start();  

echo 'Hello World';  // save to output buffer

$output = ob_get_clean();  // Get content from the output buffer, and discard the output buffer ...
$output = strtoupper($output); // manipulate the output  

echo $output;  // send to output stream / Browser

// OUTPUT:  
HELLO WORLD

Examples: Hackingwithphp.com

More info about Output buffer with examples can be found here:

http://www.hackingwithphp.com/13/0/0/output-buffering

I like the following approach as it works for all situations:

$(':focus').blur();

if(typeof theObject['key'] != 'undefined'){
     //key exists, do stuff
}

//or

if(typeof theObject.key != 'undefined'){
    //object exists, do stuff
}

I'm writing here because no one seems to give the right answer..

I know it's old...

Somebody might question the same thing..

If someone was looking for a way to remove all instances of repeated values, see "How can I efficiently extract repeated elements in a Ruby array?".

a = [1, 2, 2, 3]
counts = Hash.new(0)
a.each { |v| counts[v] += 1 }
p counts.select { |v, count| count == 1 }.keys # [1, 3]

Here is some more cool knowledge to go with this:

I had a situation where I needed to be able to find folders based on a bit of criteria in the record and then open the folder(s) that were found. While doing work on finding a solution I created a small database that asks for a search starting folder gives a place for 4 pieces of criteria and then allows the user to do criteria matching that opens the 4 (or more) possible folders that match the entered criteria.

Here is the whole code on the form:

Option Compare Database
Option Explicit

Private Sub cmdChooseFolder_Click()

    Dim inputFileDialog As FileDialog
    Dim folderChosenPath As Variant

    If MsgBox("Clear List?", vbYesNo, "Clear List") = vbYes Then DoCmd.RunSQL "DELETE * FROM tblFileList"

The form has a subform based on the table, the form has 4 text boxes for the criteria, 2 buttons leading to the click procedures and 1 other text box to store the string for the start folder. There are 2 text boxes that are used to show the number of folders listed and the number processed when searching them for the criteria.

If I had the Rep I would post a picture... :/

I have some other things I wanted to add to this code but haven't had the chance yet. I want to have a way to store the ones that worked in another table or get the user to mark them as good to store.

I can not claim full credit for all the code, I cobbled some of it together from stuff I found all around, even in other posts on stackoverflow.

I really like the idea of posting questions here and then answering them yourself because as the linked article says, it makes it easy to find the answer for later reference.

When I finish the other parts I want to add I will post the code for that too. :)

Here is an article that explains it all, with their performance difference and usage over JOINS.

SQL Server CROSS APPLY and OUTER APPLY over JOINS

As suggested in this article, there is no performance difference between them for normal join operations (INNER AND CROSS).

The usage difference arrives when you have to do a query like this:

CREATE FUNCTION dbo.fn_GetAllEmployeeOfADepartment(@DeptID AS INT)  
RETURNS TABLE 
AS 
RETURN 
   ( 
   SELECT * FROM Employee E 
   WHERE E.DepartmentID = @DeptID 
   ) 
GO 
SELECT * FROM Department D 
CROSS APPLY dbo.fn_GetAllEmployeeOfADepartment(D.DepartmentID)

That is, when you have to relate with function. This cannot be done using INNER JOIN, which would give you the error "The multi-part identifier "D.DepartmentID" could not be bound." Here the value is passed to the function as each row is read. Sounds cool to me. :)

You can try the following code to convert the image to hex string

<?php
$image = 'sample.bmp';
$file = fopen($image, 'r') or die("Could not open $image");
while ($file && !feof($file)){
$chunk = fread($file, 1000000); # You can affect performance altering
this number. YMMV.
# This loop will be dog-slow, almost for sure...
# You could snag two or three bytes and shift/add them,
# but at 4 bytes, you violate the 7fffffff limit of dechex...
# You could maybe write a better dechex that would accept multiple bytes
# and use substr... Maybe.
for ($byte = 0; $byte < strlen($chunk); $byte++)){
echo dechex(ord($chunk[$byte]));
}
}
?>

There is a pretty simple fix for this, the border-spacing and border-collapse CSS attributes work on display: table.

You can use the following to get padding/margins in your cells.

.container {_x000D_
  width: 850px;_x000D_
  padding: 0;_x000D_
  display: table;_x000D_
  margin-left: auto;_x000D_
  margin-right: auto;_x000D_
  border-collapse: separate;_x000D_
  border-spacing: 15px;_x000D_
}_x000D_
_x000D_
.row {_x000D_
  display: table-row;_x000D_
}_x000D_
_x000D_
.home_1 {_x000D_
  width: 64px;_x000D_
  height: 64px;_x000D_
  padding-right: 20px;_x000D_
  margin-right: 10px;_x000D_
  display: table-cell;_x000D_
}_x000D_
_x000D_
.home_2 {_x000D_
  width: 350px;_x000D_
  height: 64px;_x000D_
  padding: 0px;_x000D_
  vertical-align: middle;_x000D_
  font-size: 150%;_x000D_
  display: table-cell;_x000D_
}_x000D_
_x000D_
.home_3 {_x000D_
  width: 64px;_x000D_
  height: 64px;_x000D_
  padding-right: 20px;_x000D_
  margin-right: 10px;_x000D_
  display: table-cell;_x000D_
}_x000D_
_x000D_
.home_4 {_x000D_
  width: 350px;_x000D_
  height: 64px;_x000D_
  padding: 0px;_x000D_
  vertical-align: middle;_x000D_
  font-size: 150%;_x000D_
  display: table-cell;_x000D_
}

<div class="container">_x000D_
  <div class="row">_x000D_
    <div class="home_1">Foo</div>_x000D_
    <div class="home_2">Foo</div>_x000D_
    <div class="home_3">Foo</div>_x000D_
    <div class="home_4">Foo</div>_x000D_
  </div>_x000D_
_x000D_
  <div class="row">_x000D_
    <div class="home_1">Foo</div>_x000D_
    <div class="home_2">Foo</div>_x000D_
  </div>_x000D_
</div>

Note that you have to have

border-collapse: separate;

Otherwise it will not work.

login in the terminal as a root and execute this command:

mysql_secure_installation

Type n in order to not change root password and hit enter, then type y to remove anonymous users and hit enter. Type n if you want to disallow root login remotely and hit enter. Now type y to remove test tables and databases and hit enter, then type y again and hit enter.

and you are good to go :)

I wanted a simple example of the use of case that I could play with, this doesn't even need a table. This returns odd or even depending whether seconds is odd or even

SELECT CASE MOD(SECOND(NOW()),2) WHEN 0 THEN 'odd' WHEN 1 THEN 'even' END;

Let me assume that you have done the 'this' binding of 'sendThru' function.

The below functions clears the input fields when the method is triggered.

sendThru() {
    this.inputTitle.value = "";
    this.inputEntry.value = "";
}

Refs can be written as inline function expression:

ref={el => this.inputTitle = el}

where el refers to the component.

When refs are written like above, React sees a different function object each time so on every update, ref will be called with null immediately before it's called with the component instance.

Read more about it here.

Evaluating the error response from another service invocated...

This was my solution for evaluating the error:

try {
        return authenticationFeign.signIn(userDto, dataRequest);
    }catch(FeignException ex){

        //ex.status();

        if(ex.status() == HttpStatus.UNAUTHORIZED.value()){
            System.out.println("is a error 401");
            return new ResponseEntity<>(HttpStatus.UNAUTHORIZED);
        }
        return new ResponseEntity<>(HttpStatus.OK);

    }

As of October 2014:

For latest remote version:

npm view <module_name> version  

Note, version is singular.

If you'd like to see all available (remote) versions, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

To get the version you actually have locally you could use:

npm list --depth=0 | grep <module_name>

Note, even with package.json declaring your versions, the installed version might actually differ slightly - for instance if tilda was used in the version declaration

Should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

return Redirect::away($url); should work to redirect

Also, return Redirect::to($url); to redirect inside the view.

ALTER TABLE Testing ALTER COLUMN TestDec decimal(16,1)

Just put decimal(precision, scale), replacing the precision and scale with your desired values.

I haven't done any testing with this with data in the table, but if you alter the precision, you would be subject to losing data if the new precision is lower.

When you log on Windows creates an access token. This identifies you, the groups you are a member of and your privileges. And note that whether a user is an administrator or not is determined by whether the user is a member of the Administrators group.

Without UAC, when you run a program it gets a copy of the access token, and this controls what the program can access.

With UAC, when you run a program it gets a restricted access token. This is the original access token with "Administrators" removed from the list of groups (and some other changes). Even though your user is a member of the Administrators group, the program can't use Administrator privileges.

When you select "Run as Administrator" and your user is an administrator the program is launched with the original unrestricted access token. If your user is not an administrator you are prompted for an administrator account, and the program is run under that account.

This is how I converted a number to an ASCII code. 0 though 9 in hex code is 0x30-0x39. 6 would be 0x36.

unsigned int temp = 6;
or you can use unsigned char temp = 6;
unsigned char num;
 num = 0x30| temp;

this will give you the ASCII value for 6. You do the same for 0 - 9

to convert ASCII to a numeric value I came up with this code.

unsigned char num,code;
code = 0x39; // ASCII Code for 9 in Hex
num = 0&0F & code;

have you tried this: https://github.com/v2tec/watchtower. it's a simple tool running in docker container watching other containers, if their base image changed, it will pull and redeploy.

Do it like this:

char s[256];
strcpy(s, "one two three");
char* token = strtok(s, " ");
while (token) {
    printf("token: %s\n", token);
    token = strtok(NULL, " ");
}

Note: strtok modifies the string its tokenising, so it cannot be a const char*.

This should refresh the data cached by Intellisense to provide typeahead support and pre-execution error detection.

<c:if test="${companies.size() > 0}">

</c:if>

This syntax works only in EL 2.2 or newer (Servlet 3.0 / JSP 2.2 or newer). If you're facing a XML parsing error because you're using JSPX or Facelets instead of JSP, then use gt instead of >.

<c:if test="${companies.size() gt 0}">

</c:if>

If you're actually facing an EL parsing error, then you're probably using a too old EL version. You'll need JSTL fn:length() function then. From the documentation:

length( java.lang.Object) - Returns the number of items in a collection, or the number of characters in a string.

Put this at the top of JSP page to allow the fn namespace:

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

Or if you're using JSPX or Facelets:

<... xmlns:fn="http://java.sun.com/jsp/jstl/functions">

And use like this in your page:

<p>The length of the companies collection is: ${fn:length(companies)}</p>

So to test with length of a collection:

<c:if test="${fn:length(companies) gt 0}">

</c:if>

Alternatively, for this specific case you can also simply use the EL empty operator:

<c:if test="${not empty companies}">

</c:if>

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

Argparse4j is best I have found. It mimics Python's argparse libary which is very convenient and powerful.

Maybe it is a better solution.

For those using CygWin on Vista, Win7, or above, the native git command can create "proper" symlinks that are recognized by Windows apps such as Android Studio. You just need to set the CYGWIN environment variable to include winsymlinks:native or winsymlinks:nativestrict as such:

export CYGWIN="$CYGWIN winsymlinks:native"

The downside to this (and a significant one at that) is that the CygWin shell has to be "Run as Administrator" in order for it to have the OS permissions required to create those kind of symlinks. Once they're created, though, no special permissions are required to use them. As long they aren't changed in the repository by another developer, git thereafter runs fine with normal user permissions.

Personally, I use this only for symlinks that are navigated by Windows apps (i.e. non-CygWin) because of this added difficulty.

For more information on this option, see this SO question: How to make symbolic link with cygwin in Windows 7

If you want to have a valid xhtml document then you cannot put a div inside of a paragraph.

Also, a div with the property display: inline-block works differently than a span. A span is by default an inline element, you cannot set the width, height, and other properties associated with blocks. On the other hand, an element with the property inline-block will still "flow" with any surrounding text but you may set properties such as width, height, etc. A span with the property display:block will not flow in the same way as an inline-block element but will create a carriage return and have default margin.

Note that inline-block is not supported in all browsers. For instance in Firefox 2 and less you must use:

display: -moz-inline-stack;

which displays slightly different than an inline block element in FF3.

There is a great article here on creating cross browser inline-block elements.

To get around the process launch failed: Security issue and immediately launch the app on your device, tap the app icon on your iOS device after running the app via Xcode.

This will allow you to immediately run the app. It may not actually "fix" the root issue that is causing these permission alerts.

Be sure to tap the app icon while the Xcode alert is still shown. Otherwise the app will not run. I continually forget this vital step and am unable to run the app on my device. Thus I am documenting it here for myself and everyone else :)

1. Run the app via Xcode. You will see the security alert below. Do not press OK.

2. On your iOS device, tap the newly installed app icon:

3. After tapping the icon, you should now see an alert asking you to "Trust" the Untrusted App Developer. After doing so the app will immediately run, unconnected to the Xcode debugger.

   • If you do not see this "Trust" alert, you likely pressed "OK" in Xcode too soon. Do not press "OK" on the Xcode alert until after trusting the developer.

4. Finally, go back and press "OK" on the Xcode alert. You will have to re-run the app to connect the running app on your iOS device to the Xcode debugger.

I also had this problem, but when using Apache and mod_mono. For anyone else in that situation, you need to restart Apache after changing web.config to force the new version to be read.

We released a new library: PySimpleSOAP, that provides support for simple and functional client/server. It goals are: ease of use and flexibility (no classes, autogenerated code or xml is required), WSDL introspection and generation, WS-I standard compliance, compatibility (including Java AXIS, .NET and Jboss WS). It is included into Web2Py to enable full-stack solutions (complementing other supported protocols such as XML_RPC, JSON, AMF-RPC, etc.).

If someone is learning SOAP or want to investigate it, I think it is a good choice to start.

Depending on what you want to do, you can try:

browser.waitForAngular();

or

btnLoginEl.click().then(function() {
  // do some stuff 
}); 

to solve the promise. It would be better if you can do that in the beforeEach.

NB: I noticed that the expect() waits for the promise inside (i.e. getCurrentUrl) to be solved before comparing.

You have installed the Java Runtime Environment(JRE) but it doesn't contain javac.

So on the terminal get access to the root user sudo -i and enter the password. Type yum install java-devel, hence it will install packages of javac in fedora.

I just had this problem myself, searched everywhere for a solution that didn't involve killing my cache or downloading a plugin.

I didn't see this thread immediately so I found something else instead which is an interesting fix and (I think) worthy of posting here:

$('.image').load(function(){
    // stuff
}).attr('src', 'new_src');

I actually got this idea from the comments here: http://www.witheringtree.com/2009/05/image-load-event-binding-with-ie-using-jquery/

I have no idea why it works but I have tested this on IE7 and where it broke before it now works.

Hope it helps,

Edit

The accepted answer actually explains why:

If the src is already set then the event is firing in the cache cased before you get the event handler bound.

The bold property of the font itself is read only, but the actual font property of the text box is not. You can change the font of the textbox to bold as follows:

  textBox1.Font = new Font(textBox1.Font, FontStyle.Bold);

And then back again:

  textBox1.Font = new Font(textBox1.Font, FontStyle.Regular);

Mongo includes a mongoexport utility (see docs) which can dump a collection. This utility uses the native libmongoclient and is likely the fastest method.

mongoexport -d <database> -c <collection_name>

Also helpful:

-o: write the output to file, otherwise standard output is used (docs)

--jsonArray: generates a valid json document, instead of one json object per line (docs)

--pretty: outputs formatted json (docs)

Simple solution which will work on,

• Input scroll events

• Copy paste via keyboard

• Copy paste via mouse

• Input type etc cases

  <input id="maxLengthCheck" 
         name="maxLengthCheck" 
         type="number" 
         step="1" 
         min="0" 
         oninput="this.value = this.value > 5 ? 5 : Math.abs(this.value)" />
  

See there is condition on this.value > 5, just update 5 with your max limit.

Explanation:

• If our input number is more then our limit update input value this.value with proper number Math.abs(this.value)

• Else just make it to your max limit which is again 5.

Here's how you can add additional certificates to your KeyStore to avoid this problem: Trusting all certificates using HttpClient over HTTPS

It won't prompt the user like you ask, but it will make it less likely that the user will run into a "Not trusted server certificate" error.

There are method join for string objects:

".".join(("a","b","c"))

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

Old code, but this is what I've been using:

    {
        var toReturn = new List<T>(max);
        foreach (var item in source)
        {
            toReturn.Add(item);
            if (toReturn.Count == max)
            {
                yield return toReturn;
                toReturn = new List<T>(max);
            }
        }
        if (toReturn.Any())
        {
            yield return toReturn;
        }
    }

This is what I got from the Spring 3.0.x Reference Manual :-

Tip

If you intend to express annotation-driven injection by name, do not primarily use @Autowired, even if is technically capable of referring to a bean name through @Qualifier values. Instead, use the JSR-250 @Resource annotation, which is semantically defined to identify a specific target component by its unique name, with the declared type being irrelevant for the matching process.

As a specific consequence of this semantic difference, beans that are themselves defined as a collection or map type cannot be injected through @Autowired, because type matching is not properly applicable to them. Use @Resource for such beans, referring to the specific collection or map bean by unique name.

@Autowired applies to fields, constructors, and multi-argument methods, allowing for narrowing through qualifier annotations at the parameter level. By contrast, @Resource is supported only for fields and bean property setter methods with a single argument. As a consequence, stick with qualifiers if your injection target is a constructor or a multi-argument method.

Have you read this :

Delegates are a useful construct in event-based systems. Essentially Delegates are objects that encode a method dispatch on a specified object. This document shows how java inner classes provide a more generic solution to such problems.

What is a Delegate? Really it is very similar to a pointer to member function as used in C++. But a delegate contains the target object alongwith the method to be invoked. Ideally it would be nice to be able to say:

obj.registerHandler(ano.methodOne);

..and that the method methodOne would be called on ano when some specific event was received.

This is what the Delegate structure achieves.

Java Inner Classes

It has been argued that Java provides this functionality via anonymous inner classes and thus does not need the additional Delegate construct.

obj.registerHandler(new Handler() {
        public void handleIt(Event ev) {
            methodOne(ev);
        }
      } );

At first glance this seems correct but at the same time a nuisance. Because for many event processing examples the simplicity of the Delegates syntax is very attractive.

General Handler

However, if event-based programming is used in a more pervasive manner, say, for example, as a part of a general asynchronous programming environment, there is more at stake.

In such a general situation, it is not sufficient to include only the target method and target object instance. In general there may be other parameters required, that are determined within the context when the event handler is registered.

In this more general situation, the java approach can provide a very elegant solution, particularly when combined with use of final variables:

void processState(final T1 p1, final T2 dispatch) { 
  final int a1 = someCalculation();

  m_obj.registerHandler(new Handler() {
    public void handleIt(Event ev) {
     dispatch.methodOne(a1, ev, p1);
    }
  } );
}

final * final * final

Got your attention?

Note that the final variables are accessible from within the anonymous class method definitions. Be sure to study this code carefully to understand the ramifications. This is potentially a very powerful technique. For example, it can be used to good effect when registering handlers in MiniDOM and in more general situations.

By contrast, the Delegate construct does not provide a solution for this more general requirement, and as such should be rejected as an idiom on which designs can be based.

Starting from Carra's solution you can also write it as:

foreach(var person in personList.Where(el => !myDictionary.ContainsKey(el.FirstAndLastName)))
{
    myDictionary.Add(person.FirstAndLastName, person);
}

This would redirect with posted data

$(function() {
       $('<form action="url.php" method="post"><input type="hidden" name="name" value="value1"></input></form>').appendTo('body').submit().remove();
    });

    }

the .submit() function does the submit to url automatically
the .remove() function kills the form after submitting

Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.

Do you have this:

use Cartalyst\Sentry\Sentry; 

In your code?

Ok, but if this line is working for you:

$user = $this->sentry->register(array(     'username' => e($data['username']),     'email' => e($data['email']),      'password' => e($data['password'])     )); 

So you already have it instantiated and you can surely do:

$adminGroup = $this->sentry->findGroupById(5); 

I had the same issue. I used the following steps to make it work

sudo pip uninstall virtualenv

sudo -H pip install virtualenv

That is it. It started working.

Usage of sudo -H----> sudo -H: set HOME variable to target user's home dir.

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

Better yet, consider sp_getapplock which is designed for this. Or use SET LOCK_TIMEOUT

Otherwise, you'd have to do something with sys.dm_tran_locks which I'd use only for DBA stuff: not for user defined concurrency.

UPDATED

For IntelliJ IDEA 12+ releases we can build automatically the edited sources if we are using the external compiler option. The only thing needed is to check the option "Build project automatically", located under "Compiler" settings:

Also, if you would like to hot deploy, while the application is running or if you are using spring boot devtools you should enable the compiler.automake.allow.when.app.running from registry too. This will automatically compile your changes.

Using Ctrl+Shift+A (or ?+Shift+A on Mac) type Registry once the registry windows is open, locate and enable compiler.automake.allow.when.app.running, see here:

For more tips see the "Migrating From Eclipse to IntelliJ IDEA" guide.

I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.

public List<User> getUser(int userId) {
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = createPreparedStatement(con, userId); 
         ResultSet rs = ps.executeQuery()) {

         // process the resultset here, all resources will be cleaned up

    } catch (SQLException e) {
        e.printStackTrace();
    }
}

private PreparedStatement createPreparedStatement(Connection con, int userId) throws SQLException {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    PreparedStatement ps = con.prepareStatement(sql);
    ps.setInt(1, userId);
    return ps;
}

<div id="elem" class="className"></div>

With Javascript

document.getElementById('elem').className;

With jQuery

$('#elem').attr('class');

OR

$('#elem').get(0).className;

This cannot be done with pure HTML. You must rely on JavaScript for this trick.

However, if you place two forms on the HTML page you can do this.

Form1 would have the previous button.

Form2 would have any user inputs + the next button.

When the user presses Enter in Form2, the Next submit button would fire.

A bash solution :

docker history --no-trunc $argv  | tac | tr -s ' ' | cut -d " " -f 5- | sed 's,^/bin/sh -c #(nop) ,,g' | sed 's,^/bin/sh -c,RUN,g' | sed 's, && ,\n  & ,g' | sed 's,\s*[0-9]*[\.]*[0-9]*\s*[kMG]*B\s*$,,g' | head -n -1

Step by step explanations:

tac : reverse the file

jQuery is JavaScript! It's just a JavaScript framework. So to find a random item, just use plain old JavaScript, for example,

var randomItem = items[Math.floor(Math.random()*items.length)]

.container-fluid {
    margin-right: auto;
    margin-left: auto;
    padding-left:0px;
    padding-right:0px;
}

If you're open to using jQuery:

<script type="text/javascript">
 function fncsave()
 {
    $('#<%= savebtn.ClientID %>').click();
 }
</script>

Also, if you are using .NET 4 or better you can make the ClientIDMode == static and simplify the code:

<script type="text/javascript">
 function fncsave()
 {
    $("#savebtn").click();
 }
</script>

Reference: MSDN Article for Control.ClientIDMode

An example of this exception being thrown is: When you are trying to check something, that is null.

For example:

string testString = null; //Because it doesn't have a value (i.e. it's null; "Length" cannot do what it needs to do)

if (testString.Length == 0) // Throws a nullreferenceexception
{
    //Do something
} 

The .NET runtime will throw a NullReferenceException when you attempt to perform an action on something which hasn't been instantiated i.e. the code above.

In comparison to an ArgumentNullException which is typically thrown as a defensive measure if a method expects that what is being passed to it is not null.

More information is in C# NullReferenceException and Null Parameter.

//Recursive solution
class SLL
{
   int data;
   SLL next;
}

SLL reverse(SLL head)
{
  //base case - 0 or 1 elements
  if(head == null || head.next == null) return head;

  SLL temp = reverse(head.next);
  head.next.next = head;
  head.next = null;
  return temp;
}

Try this:

var body = document.getElementsByTagName('BODY')[0];
// CONDITION DOES NOT WORK
if ((body && body.readyState == 'loaded') || (body &&  body.readyState == 'complete') ) {
    DoStuffFunction();
} else {
    // CODE BELOW WORKS
    if (window.addEventListener) {
        window.addEventListener('load', DoStuffFunction, false);
    } else {
        window.attachEvent('onload',DoStuffFunction);
    }
}

Curl has a specific option, --write-out, for this:

$ curl -o /dev/null --silent --head --write-out '%{http_code}\n' <url>
200

• -o /dev/null throws away the usual output
• --silent throws away the progress meter
• --head makes a HEAD HTTP request, instead of GET
• --write-out '%{http_code}\n' prints the required status code

To wrap this up in a complete Bash script:

#!/bin/bash
while read LINE; do
  curl -o /dev/null --silent --head --write-out "%{http_code} $LINE\n" "$LINE"
done < url-list.txt

(Eagle-eyed readers will notice that this uses one curl process per URL, which imposes fork and TCP connection penalties. It would be faster if multiple URLs were combined in a single curl, but there isn't space to write out the monsterous repetition of options that curl requires to do this.)

Well, I figured out the way and thought to share with the people out there who might run into the same problem.

Let me start with the problem I had been facing,

I had been trying to execute a Dynamic Sql Statement that used two temporary tables I declared at the top of my stored procedure, but because that dynamic sql statment created a new scope, I couldn't use the temporary tables.

Solution:

I simply changed them to Global Temporary Variables and they worked.

Find my stored procedure underneath.

CREATE PROCEDURE RAFCustom_Room_GetRelatedProducts
-- Add the parameters for the stored procedure here
@PRODUCT_SKU nvarchar(15) = Null

AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;

IF OBJECT_ID('tempdb..##RelPro', 'U') IS NOT NULL
BEGIN
    DROP TABLE ##RelPro
END

Create Table ##RelPro
(
    RowID int identity(1,1),
    ID int,
    Item_Name nvarchar(max),
    SKU nvarchar(max),
    Vendor nvarchar(max),
    Product_Img_180 nvarchar(max),
    rpGroup int,
    Assoc_Item_1 nvarchar(max),
    Assoc_Item_2 nvarchar(max),
    Assoc_Item_3 nvarchar(max),
    Assoc_Item_4 nvarchar(max),
    Assoc_Item_5 nvarchar(max),
    Assoc_Item_6 nvarchar(max),
    Assoc_Item_7 nvarchar(max),
    Assoc_Item_8 nvarchar(max),
    Assoc_Item_9 nvarchar(max),
    Assoc_Item_10 nvarchar(max)
);

Begin
    Insert ##RelPro(ID, Item_Name, SKU, Vendor, Product_Img_180, rpGroup)

    Select distinct zp.ProductID, zp.Name, zp.SKU,
        (Select m.Name From ZNodeManufacturer m(nolock) Where m.ManufacturerID = zp.ManufacturerID),
        'http://s0001.server.com/is/sw11/DG/' + 
        (Select m.Custom1 From ZNodeManufacturer m(nolock) Where m.ManufacturerID = zp.ManufacturerID) +
        '_' + zp.SKU + '_3?$SC_3243$', ep.RoomID
    From Product zp(nolock) Inner Join RF_ExtendedProduct ep(nolock) On ep.ProductID = zp.ProductID
    Where zp.ActiveInd = 1 And SUBSTRING(zp.SKU, 1, 2) <> 'GC' AND zp.Name <> 'PLATINUM' AND zp.SKU = (Case When @PRODUCT_SKU Is Not Null Then @PRODUCT_SKU Else zp.SKU End)
End

declare @curr_row int = 0,
        @tot_rows int= 0,
        @sku nvarchar(15) = null;

IF OBJECT_ID('tempdb..##TSku', 'U') IS NOT NULL
BEGIN
    DROP TABLE ##TSku
END
Create Table ##TSku (tid int identity(1,1), relsku nvarchar(15));

Select @curr_row = (Select MIN(RowId) From ##RelPro);
Select @tot_rows = (Select MAX(RowId) From ##RelPro);

while @curr_row <= @tot_rows
Begin
    select @sku = SKU from ##RelPro where RowID = @curr_row;

    truncate table ##TSku;

    Insert ##TSku(relsku)
    Select distinct top(10) tzp.SKU From Product tzp(nolock) INNER JOIN 
    [INTRANET].raf_FocusAssociatedItem assoc(nolock) ON assoc.associatedItemID = tzp.SKU
    Where (assoc.isActive=1) And (tzp.ActiveInd = 1) AND (assoc.productID = @sku)

    declare @curr_row1 int = (Select Min(tid) From ##TSku),
            @tot_rows1 int = (Select Max(tid) From ##TSku);

    If(@tot_rows1 <> 0)
    Begin
        While @curr_row1 <= @tot_rows1
        Begin
            declare @col_name nvarchar(15) = null,
                    @sqlstat nvarchar(500) = null;
            set @col_name =  'Assoc_Item_' + Convert(nvarchar(2), @curr_row1);
            set @sqlstat = 'update ##RelPro set ' + @col_name + ' = (Select relsku From ##TSku Where tid = ' + Convert(nvarchar(2), @curr_row1) + ') Where RowID = ' + Convert(nvarchar(2), @curr_row);
            Exec(@sqlstat);
            set @curr_row1 = @curr_row1 + 1;
        End
    End
    set @curr_row = @curr_row + 1;
End

Select * From ##RelPro;

END GO

You need to allow Allow USB debugging when the popup shows up when you first connect to the computer!

If you want to know whether an object is an Integer or something which can meaningfully be converted to an Integer (NOT including things like "hello", which to_i will convert to 0):

result = Integer(obj) rescue false

How about installing pyobdc from zip file? From How to connect to Microsoft Sql Server from Ubuntu using pyODBC:

Download source vs apt-get

The apt-get utility in Ubuntu does have a version of pyODBC. (version 2.1.7).
However, it is badly out-of-date (2.1.7 vs 3.0.6) and may not work well with the newer versions of unixODBC and freetds.
This is especially important if you are trying to connect to later versions of Microsoft Sql Server (2008 onwards).
It is recommended that you use the latest versions of unixODBC, freetds and pyODBC when working with the latest Microsoft Sql Server instead of relying on packages in apt-get.

I might be missing something, but afaik, you get undefined only

Update: Ok, I missed a lot, trying to complete:

You get undefined...

... when you try to access properties of an object that don't exist:

var a = {}
a.foo // undefined

... when you have declared a variable but not initialized it:

var a;
// a is undefined

... when you access a parameter for which no value was passed:

function foo (a, b) {
    // something
}

foo(42); // b inside foo is undefined

... when a function does not return a value:

function foo() {};
var a = foo(); // a is undefined

It might be that some built-in functions return null on some error, but if so, then it is documented. null is a concrete value in JavaScript, undefined is not.

Normally you don't need to distinguish between those. Depending on the possible values of a variable, it is sufficient to use if(variable) to test whether a value is set or not (both, null and undefined evaluate to false).

Also different browsers seem to be returning these differently.

Please give a concrete example.

I've had better luck with calling the gotoDate in the viewRender callback:

$('#calendar').fullCalendar({
  firstDay: 0,
  defaultView: 'basicWeek',
  header: {
    left: '',
    center: 'basicDay,basicWeek,month',
    right:  'today prev,next'
  },
  viewRender: function(view, element) {
    $('#calendar').fullCalendar( 'gotoDate', 2014, 4, 24 );
  }
});

Calling gotoDate outside of the callback didn't have the expected results due to a race condition.

Generally speaking, I tend to use path parameters when there is an obvious 'hierarchy' in the resource, such as:

/region/state/42

If that single resource has a status, one could:

/region/state/42/status

However, if 'region' is not really part of the resource being exposed, it probably belongs as one of the query parameters - similar to pagination (as you mentioned).

Ruby Shoes (by why) is intended to be a really simple GUI framework. I don't know how fully featured it is, though.

Some good code samples can be found in the tutorials.

Also, I think shoes powers hackety hack, a compelling programming learning environment for youngsters.

As Tyler points out, there's no way to do what you require "directly and reliably", since a given FD may correspond to 0 filenames (in various cases) or > 1 (multiple "hard links" is how the latter situation is generally described). If you do still need the functionality with all the limitations (on speed AND on the possibility of getting 0, 2, ... results rather than 1), here's how you can do it: first, fstat the FD -- this tells you, in the resulting struct stat, what device the file lives on, how many hard links it has, whether it's a special file, etc. This may already answer your question -- e.g. if 0 hard links you will KNOW there is in fact no corresponding filename on disk.

If the stats give you hope, then you have to "walk the tree" of directories on the relevant device until you find all the hard links (or just the first one, if you don't need more than one and any one will do). For that purpose, you use readdir (and opendir &c of course) recursively opening subdirectories until you find in a struct dirent thus received the same inode number you had in the original struct stat (at which time if you want the whole path, rather than just the name, you'll need to walk the chain of directories backwards to reconstruct it).

If this general approach is acceptable, but you need more detailed C code, let us know, it won't be hard to write (though I'd rather not write it if it's useless, i.e. you cannot withstand the inevitably slow performance or the possibility of getting != 1 result for the purposes of your application;-).

git will show changes in commits that affect the index, such as git rm. It does not store a log of all git commands you execute.

However, a large number of git commands affect the index in some way, such as creating a new branch. These changes will show up in the commit history, which you can view with git log.

However, there are destructive changes that git can't track, such as git reset.

So, to answer your question, git does not store an absolute history of git commands you've executed in a repository. However, it is often possible to interpolate what command you've executed via the commit history.

Count() is an extension method introduced by LINQ while the Count property is part of the List itself (derived from ICollection). Internally though, LINQ checks if your IEnumerable implements ICollection and if it does it uses the Count property. So at the end of the day, there's no difference which one you use for a List.

To prove my point further, here's the code from Reflector for Enumerable.Count()

public static int Count<TSource>(this IEnumerable<TSource> source)
{
    if (source == null)
    {
        throw Error.ArgumentNull("source");
    }
    ICollection<TSource> is2 = source as ICollection<TSource>;
    if (is2 != null)
    {
        return is2.Count;
    }
    int num = 0;
    using (IEnumerator<TSource> enumerator = source.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            num++;
        }
    }
    return num;
}

Yeah it suck to get stuck in Scale View.

Host+Home will popup the Virtual machine settings. (by default Host is Right Control)

From there you can change the view settings, as the Menu bar is hidden in Scale View.

Had the same issue, especially when you checked the box not to show the 'Switch to Scale view' dialog.

This you can do while the VM is running.

Now that Javascript has lookbehind (as of ES2018), on newer environments, you can avoid groups entirely in situations like these. Rather, lookbehind for what comes before the group you were capturing, and lookahead for what comes after, and replace with just !NEW_ID!:

const str = 'name="some_text_0_some_text"';
console.log(
  str.replace(/(?<=name="\w+)\d+(?=\w+")/, '!NEW_ID!')
);

With this method, the full match is only the part that needs to be replaced.

• (?<=name="\w+) - Lookbehind for name=", followed by word characters (luckily, lookbehinds do not have to be fixed width in Javascript!)
• \d+ - Match one or more digits - the only part of the pattern not in a lookaround, the only part of the string that will be in the resulting match
• (?=\w+") - Lookahead for word characters followed by " `

Keep in mind that lookbehind is pretty new. It works in modern versions of V8 (including Chrome, Opera, and Node), but not in most other environments, at least not yet. So while you can reliably use lookbehind in Node and in your own browser (if it runs on a modern version of V8), it's not yet sufficiently supported by random clients (like on a public website).

let dt = new Date('2013-03-10T02:00:00Z');

let mm = dt.getMonth() + 1;
let yyyy = dt.getFullYear();

    dd = '0' + dd;
}
if (mm<10) {
    mm = '0' + mm;
}
return yyyy + '-' + mm + '-' + dd;

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).

When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization can convert these complex objects into byte strings for such use. After the byte strings are transmitted, the receiver will have to recover the original object from the byte string. This is known as deserialization.

Say, you have an object:

{foo: [1, 4, 7, 10], bar: "baz"}

serializing into JSON will convert it into a string:

'{"foo":[1,4,7,10],"bar":"baz"}'

which can be stored or sent through wire to anywhere. The receiver can then deserialize this string to get back the original object. {foo: [1, 4, 7, 10], bar: "baz"}.

I recently had to resolve this issue and here's what I did :

First of all, this solution is around tuning Apache server.

Second main think is that there's a bug in the IE9 which means that the meta tag will not work, instead of this solution try this

On Windows 2008 R2, I have seen application crash dumps under either

C:\Users\[Some User]\Microsoft\Windows\WER\ReportArchive

or

C:\ProgramData\Microsoft\Windows\WER\ReportArchive

I don't know how Windows decides which directory to use.

I have seen some solutions here worth noting, as Omer Eldan posted. but here follows. ASP C#

using System.Data;
using System.Web.UI.HtmlControls;

public static Table DataTableToHTMLTable(DataTable dt, bool includeHeaders)
{
    Table tbl = new Table();
    TableRow tr = null;
    TableCell cell = null;

    int rows = dt.Rows.Count;
    int cols = dt.Columns.Count;

    if (includeHeaders)
    {
        TableHeaderRow htr = new TableHeaderRow();
        TableHeaderCell hcell = null;
        for (int i = 0; i < cols; i++)
        {
            hcell = new TableHeaderCell();
            hcell.Text = dt.Columns[i].ColumnName.ToString();
            htr.Cells.Add(hcell);
        }
        tbl.Rows.Add(htr);
    }

    for (int j = 0; j < rows; j++)
    {
        tr = new TableRow();
        for (int k = 0; k < cols; k++)
        {
            cell = new TableCell();
            cell.Text = dt.Rows[j][k].ToString();
            tr.Cells.Add(cell);
        }
        tbl.Rows.Add(tr);
    }
    return tbl;
}

why this solution? Because you can easily just add this to a panel ie:

panel.Controls.Add(DataTableToHTMLTable(dtExample,true));

Second question , why do you have one column datatables and not just array's? Are you sure that these DataTables are uniform, because if the data is jagged then it's no use. If You really have to join these DataTables, there is many examples of Linq operations, or just use (beware though of same name columns as this will conflict in both linq operations and this solution if not handled):

public DataTable joinUniformTable(DataTable dt1, DataTable dt2)
{
    int dt2ColsCount = dt2.Columns.Count;
    int dt1lRowsCount = dt1.Rows.Count;

    DataColumn column;
    for (int i = 0; i < dt2ColsCount; i++)
    {
        column = new DataColumn();
        string colName = dt2.Columns[i].ColumnName;
        System.Type colType = dt2.Columns[i].DataType;
        column.ColumnName = colName;
        column.DataType = colType;
        dt1.Columns.Add(column);

        for (int j = 0; j < dt1lRowsCount; j++)
        {
            dt1.Rows[j][colName] = dt2.Rows[j][colName];
        }
    }
    return dt1;
}

and your solution would look something like:

panel.Controls.Add(DataTableToHTMLTable(joinUniformTable(joinUniformTable(LivDT,BathDT),BedDT),true));

interpret the rest, and have fun.

Finally I got it to work. Steve's answer is right but not for all cases. It fails when that view is being executed from a third schema. For that to work you have to add the grant option:

GRANT SELECT ON [TABLE_NAME] TO [READ_USERNAME] WITH GRANT OPTION;

That way, [READ_USERNAME] can also grant select privilege over the view to another schema

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

Use this API in your code.. It will help u to insert event, event with reminder and event with meeting can be enabled... This api works for platform 2.1 and above Those who uses less then 2.1 instead of content://com.android.calendar/events use content://calendar/events

You can always use the definition of xor to compute it from other logical operations:

(a and not b) or (not a and b)

But this is a little too verbose for me, and isn't particularly clear at first glance. Another way to do it is:

bool(a) ^ bool(b)

The xor operator on two booleans is logical xor (unlike on ints, where it's bitwise). Which makes sense, since bool is just a subclass of int, but is implemented to only have the values 0 and 1. And logical xor is equivalent to bitwise xor when the domain is restricted to 0 and 1.

So the logical_xor function would be implemented like:

def logical_xor(str1, str2):
    return bool(str1) ^ bool(str2)

do this in two steps:

1. replace not letter characters with this regex:

   [\/\&%#\$]

2. replace quotes with this regex:

   [\"\']

and use preg_replace:

$stringWithoutNonLetterCharacters = preg_replace("/[\/\&%#\$]/", "_", $yourString);
$stringWithQuotesReplacedWithSpaces = preg_replace("/[\"\']/", " ", $stringWithoutNonLetterCharacters);

It shouldn't be your call to decide whether the link should open in a new tab or a new window, since ultimately this choice should be done by the settings of the user's browser. Some people like tabs; some like new windows.

Using _blank will tell the browser to use a new tab/window, depending on the user's browser configuration and how they click on the link (e.g. middle click, Ctrl+click, or normal click).

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

The following function comes in three forms:

method = "mode" [default]: calculates the mode for a unimodal vector, else returns an NA
method = "nmodes": calculates the number of modes in the vector
method = "modes": lists all the modes for a unimodal or polymodal vector

modeav <- function (x, method = "mode", na.rm = FALSE)
{
  x <- unlist(x)
  if (na.rm)
    x <- x[!is.na(x)]
  u <- unique(x)
  n <- length(u)
  #get frequencies of each of the unique values in the vector
  frequencies <- rep(0, n)
  for (i in seq_len(n)) {
    if (is.na(u[i])) {
      frequencies[i] <- sum(is.na(x))
    }
    else {
      frequencies[i] <- sum(x == u[i], na.rm = TRUE)
    }
  }
  #mode if a unimodal vector, else NA
  if (method == "mode" | is.na(method) | method == "")
  {return(ifelse(length(frequencies[frequencies==max(frequencies)])>1,NA,u[which.max(frequencies)]))}
  #number of modes
  if(method == "nmode" | method == "nmodes")
  {return(length(frequencies[frequencies==max(frequencies)]))}
  #list of all modes
  if (method == "modes" | method == "modevalues")
  {return(u[which(frequencies==max(frequencies), arr.ind = FALSE, useNames = FALSE)])}  
  #error trap the method
  warning("Warning: method not recognised.  Valid methods are 'mode' [default], 'nmodes' and 'modes'")
  return()
}

If it´s in the global scope it´s better to use:

function foo()
{
    alert('foo');
}

var a = 'foo';
window[a]();

than eval(). Because eval() is evaaaaaal.

Exactly like Nosredna said 40 seconds before me that is >.<

New in django 1.7

you could use JsonResponse objects.

from the docs:

from django.http import JsonResponse
return JsonResponse({'foo':'bar'})

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.

Abstract your initialization into a method, and call the method from mounted and wherever else you want.

new Vue({
  methods:{
    init(){
      //call API
      //Setup game
    }
  },
  mounted(){
    this.init()
  }
})

Then possibly have a button in your template to start over.

<button v-if="playerWon" @click="init">Play Again</button>

In this button, playerWon represents a boolean value in your data that you would set when the player wins the game so the button appears. You would set it back to false in init.

The accepted answer here does not work for my use case. I needed to be able to dynamically create parameters in one job and pass them into another. As Mark McKenna mentions there is seemingly no way to export a variable from a shell build step to the post build actions.

I achieved a workaround using the Parameterized Trigger Plugin by writing the values to a file and using that file as the parameters to import via 'Add post-build action' -> 'Trigger parameterized build...' then selecting 'Add Parameters' -> 'Parameters from properties file'.

While the above answers work but in case you have multiple devices connected to your computer then the following command can be used to remove the app from one of them:

adb -s <device-serial> shell pm uninstall <app-package-name>

If you want to find out the device serial then use the following command:

adb devices -l

This will give you a list of devices attached. The left column shows the device serials.

For a GOOD and definite solution see the Setting up Permissions section in Installing and Configuring Symfony section :

Setting up Permissions

One common issue when installing Symfony is that the app/cache and app/logs directories must be writable both by the web server and the command line user. On a UNIX system, if your web server user is different from your command line user, you can try one of the following solutions.

1. Use the same user for the CLI and the web server

In development environments, it is a common practice to use the same UNIX user for the CLI and the web server because it avoids any of these permissions issues when setting up new projects. This can be done by editing your web server configuration (e.g. commonly httpd.conf or apache2.conf for Apache) and setting its user to be the same as your CLI user (e.g. for Apache, update the User and Group values).

2. Using ACL on a system that supports chmod +a

Many systems allow you to use the chmod +a command. Try this first, and if you get an error - try the next method. This uses a command to try to determine your web server user and set it as HTTPDUSER:

$ rm -rf app/cache/*
$ rm -rf app/logs/*

$ HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
$ sudo chmod +a "$HTTPDUSER allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
$ sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs

3. Using ACL on a system that does not support chmod +a

Some systems don't support chmod +a, but do support another utility called setfacl. You may need to enable ACL support on your partition and install setfacl before using it (as is the case with Ubuntu). This uses a command to try to determine your web server user and set it as HTTPDUSER:

$ HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
$ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
$ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs

For Symfony 3 it would be:

$ HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\  -f1`
$ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX var/cache var/logs
$ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX var/cache var/logs

If this doesn't work, try adding -n option.

4. Without using ACL

If none of the previous methods work for you, change the umask so that the cache and log directories will be group-writable or world-writable (depending if the web server user and the command line user are in the same group or not). To achieve this, put the following line at the beginning of the app/console, web/app.php and web/app_dev.php files:

umask(0002); // This will let the permissions be 0775

// or

umask(0000); // This will let the permissions be 0777

Note that using the ACL is recommended when you have access to them on your server because changing the umask is not thread-safe.

If you are talking about actually compressing the text not just shortening then Deflate/gzip (wrapper around gzip), zip work well for smaller files and text. Other algorithms are highly efficient for larger files like bzip2 etc.

Wikipedia has a list of compression times. (look for comparison of efficiency)

The following page was useful https://blogs.msdn.microsoft.com/phkelley/2014/01/20/adding-a-corporate-or-self-signed-certificate-authority-to-git-exes-store/

To add the proxy, like the other threads I used

git config --global http.proxy proxy.company.net:8080
git config --global https.proxy proxy.company.net:8080

Monolithic kernel

All the parts of a kernel like the Scheduler, File System, Memory Management, Networking Stacks, Device Drivers, etc., are maintained in one unit within the kernel in Monolithic Kernel

Advantages

•Faster processing

Disadvantages

•Crash Insecure •Porting Inflexibility •Kernel Size explosion

Examples •MS-DOS, Unix, Linux

Micro kernel

Only the very important parts like IPC(Inter process Communication), basic scheduler, basic memory handling, basic I/O primitives etc., are put into the kernel. Communication happen via message passing. Others are maintained as server processes in User Space

Advantages

•Crash Resistant, Portable, Smaller Size

Disadvantages

•Slower Processing due to additional Message Passing

Examples •Windows NT

Same principle as other answers, just thought it was quicker than re-opening terminals :)

bash -l -c "rvm use 2.0.0"

If you are connecting to the server from Windows, the Putty version of scp ("pscp") lets you pass the password with the -pw parameter.

This is mentioned in the documentation here.

collecting from Mozilla Documentation:

The NodeSelector interface This specification adds two new methods to any objects implementing the Document, DocumentFragment, or Element interfaces:

querySelector

Returns the first matching Element node within the node's subtree. If no matching node is found, null is returned.

querySelectorAll

Returns a NodeList containing all matching Element nodes within the node's subtree, or an empty NodeList if no matches are found.

and

Note: The NodeList returned by querySelectorAll() is not live, which means that changes in the DOM are not reflected in the collection. This is different from other DOM querying methods that return live node lists.

This is a bit old but I want to add a thing I think is relevant.
(I meant to comment on one or 2 threads above but it seems I need reputation 50 and I have only 21 at the time I'm writing this. :) )
Just want to say that there are times when it's much better to access the elements of a form by name rather than by id. I'm not talking about the form itself. The form, OK, you can give it an id and then access it by it. But if you have a radio button in a form, it's much easier to use it as a single object (getting and setting its value) and you can only do this by name, as far as I know.

Example:

<form id="mainForm" name="mainForm">
    <input type="radio" name="R1" value="V1">choice 1<br/>
    <input type="radio" name="R1" value="V2">choice 2<br/>
    <input type="radio" name="R1" value="V3">choice 3
</form>

You can get/set the checked value of the radio button R1 as a whole by using
document.mainForm.R1.value
or
document.getElementById("mainForm").R1.value
So if you want to have a unitary style, you might want to always use this method, regardless of the type of form element. Me, I'm perfectly comfortable accessing radio buttons by name and text boxes by id.

The Solution on top won't work because a submit redirects the page to the endpoint of form and wait for response to redirect. I see that this is an old Question but Most Asked and even i came to know the answer.Still here is my solution what i am implementing. I tried to keep it secure with Nonce but if you don't care then not required.

Method 1: You need to Pop up the form.

document.getElementById('edit_info_button').addEventListener('click',function(){
        window.open('{% url "updateuserinfo" %}','newwindow', 'width=400,height=600,scrollbars=no');
    });

Then you have the form open.

Submit the form normally.

Then return an HTTPResponse in render to a template(HTML file) With a STRICT Content Security Policy. A Variable that contains the following script. Nonce contains a Base64 128bits or larger randomly generated string for every request made to server.

<script nonce="{{nonce}}">window.close()</script>

Method 2:

Or you can redirect to another Page which is suppose to close ... Which already Contains the window.close() script. This will close the pop up window.

Method 3:

Otherwise the simplest will be Use a Ajax call if you are comfortable with one.Use then() and check your condition to the httpresponse from the server.Close the window when success.

In dashboard you can see running word press version at "At a Glance"

I don't think it is possible to do what the questioner asks which is to avoid dll hell by merging all the project files into one .exe.

The framework issue is a red herring. The problem that occurs is that when you have multiple projects depending on one library it is a PITA to keep the libraries in sync. Each time the library changes, all the .exes that depend on it and are not updated will die horribly.

Telling people to learn C as one response did is arrogant and ignorant.

You could also create an ssh tunnel.

docker-compose.yml:

---

version: '2'

services:
  kibana:
    image: "kibana:4.5.1"
    links:
      - elasticsearch
    volumes:
      - ./config/kibana:/opt/kibana/config:ro

  elasticsearch:
    build:
      context: .
      dockerfile: ./docker/Dockerfile.tunnel
    entrypoint: ssh
    command: "-N elasticsearch -L 0.0.0.0:9200:localhost:9200"

docker/Dockerfile.tunnel:

FROM buildpack-deps:jessie

RUN apt-get update && \
    DEBIAN_FRONTEND=noninteractive \
    apt-get -y install ssh && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*

COPY ./config/ssh/id_rsa /root/.ssh/id_rsa
COPY ./config/ssh/config /root/.ssh/config
COPY ./config/ssh/known_hosts /root/.ssh/known_hosts
RUN chmod 600 /root/.ssh/id_rsa && \
    chmod 600 /root/.ssh/config && \
    chown $USER:$USER -R /root/.ssh

config/ssh/config:

# Elasticsearch Server
Host elasticsearch
    HostName jump.host.czerasz.com
    User czerasz
    ForwardAgent yes
    IdentityFile ~/.ssh/id_rsa

This way the elasticsearch has a tunnel to the server with the running service (Elasticsearch, MongoDB, PostgreSQL) and exposes port 9200 with that service.

I have used both timers and Thread.Sleep(x), or either, depending on the situation.

If I have a short piece of code that needs to run repeadedly, I probably use a timer.

If I have a piece of code that might take longer to run than the delay timer (such as retrieving files from a remote server via FTP, where I don't control or know the network delay or file sizes / count), I will wait for a fixed period of time between cycles.

Both are valid, but as pointed out earlier they do different things. The timer runs your code every x milliseconds, even if the previous instance hasn't finished. The Thread.Sleep(x) waits for a period of time after completing each iteration, so the total delay per loop will always be longer (perhaps not by much) than the sleep period.

Assuming that start_date is before end_date,

interval [start_date..end_date] NOT BETWEEN two dates simply means that either it starts before 2009-12-15 or it ends after 2010-01-02.

Then you can simply do

start_date<CAST('2009-12-15' AS DATE) or end_date>CAST('2010-01-02' AS DATE)

Here is a summary.

1. escape() will not encode @ * _ + - . /

   Do not use it.

2. encodeURI() will not encode A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

   Use it when your input is a complete URL like 'https://searchexample.com/search?q=wiki'

3. encodeURIComponent() will not encode A-Z a-z 0-9 - _ . ! ~ * ' ( ) Use it when your input is part of a complete URL e.g const queryStr = encodeURIComponent(someString)

Another solution: go through a filter with your inverted conditions : Example :

if(subscribtion.isOnce() && subscribtion.isCalled()){
                continue;
}

can be replaced with

.filter(s -> !(s.isOnce() && s.isCalled()))

The most straightforward approach seem to be using "return;" though.
