In case you only want to purge the queues which are not empty (a lot faster):

rabbitmqctl list_queues | awk '$2!=0 { print $1 }' | sed 's/Listing//' | xargs -L1 rabbitmqctl purge_queue

For me, it takes 2-3 seconds to purge a queue (both empty and non-empty ones), so iterating through 50 queues is such a pain while I just need to purge 10 of them (40/50 are empty).

Simplest way?

text = "This is a test from a test ok" 

firstTest = text.find('test')

print text.find('test', firstTest + 1)

You can pipe the source string to findstr and check the value of ERRORLEVEL to see if the pattern string was found. A value of zero indicates success and the pattern was found. Here is an example:

::
: Y.CMD - Test if pattern in string
: P1 - the pattern
: P2 - the string to check
::
@echo off

echo.%2 | findstr /C:"%1" 1>nul

if errorlevel 1 (
  echo. got one - pattern not found
) ELSE (
  echo. got zero - found pattern
)

When this is run in CMD.EXE, we get:

C:\DemoDev>y pqrs "abc def pqr 123"
 got one - pattern not found

C:\DemoDev>y pqr "abc def pqr 123" 
 got zero - found pattern

    public void Execute(object parameter)

I hope this will give you the idea.

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

From the npm-link documentation:

In the local module directory:

$ cd ./package-dir
$ npm link

In the directory of the project to use the module:

$ cd ./project-dir
$ npm link package-name

Or in one go using relative paths:

$ cd ./project-dir
$ npm link ../package-dir

This is equivalent to using two commands above under the hood.

You can determine if as certain word is found in a cell by using

If InStr(cell.Value, "Word1") > 0 Then

If Word1 is found in the string the InStr() function will return the location of the first character of Word1 in the string.

which <cmd>

also see options which supports for aliases if applicable to your case.

Example

$ which foobar
which: no foobar in (/usr/local/bin:/usr/bin:/cygdrive/c/Program Files (x86)/PC Connectivity Solution:/cygdrive/c/Windows/system32/System32/WindowsPowerShell/v1.0:/cygdrive/d/Program Files (x86)/Graphviz 2.28/bin:/cygdrive/d/Program Files (x86)/GNU/GnuPG
$ if [ $? -eq 0 ]; then echo "foobar is found in PATH"; else echo "foobar is NOT found in PATH, of course it does not mean it is not installed."; fi
foobar is NOT found in PATH, of course it does not mean it is not installed.
$

PS: Note that not everything that's installed may be in PATH. Usually to check whether something is "installed" or not one would use installation related commands relevant to the OS. E.g. rpm -qa | grep -i "foobar" for RHEL.

There's actually no need for visibility or opacity - you can simply use color, which has the upside of keeping any "blinking" to the text only:

blink {_x000D_
    display: inline;_x000D_
    color: inherit;_x000D_
    animation: blink 1s steps(1) infinite;_x000D_
    -webkit-animation: blink 1s steps(1) infinite;_x000D_
}_x000D_
@keyframes blink { 50% { color: transparent; } }_x000D_
@-webkit-keyframes blink { 50% { color: transparent; } }

Here is some text, <blink>this text will blink</blink>, this will not.

Ubuntu 20.04:

Option 1 - set up a gem installation directory for your user account

For bash (for zsh, we would use .zshrc of course)

echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
echo 'export GEM_HOME="$HOME/gems"' >> ~/.bashrc
echo 'export PATH="$HOME/gems/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Option 2 - use snap

Uninstall the apt-version (ruby-full) and reinstall it with snap

sudo apt-get remove ruby
sudo snap install ruby --classic

function millisecondsToTime(millisecs){
  var ms = Math.abs(millisecs) % 1000;
  var secs = (millisecs < 0 ? -1 : 1) * ((Math.abs(millisecs) - ms) / 1000);
  ms = '' + ms;
  ms = '000'.substring(ms.length) + ms;
  return secsToTime(secs) + '.' + ms;
}

You can use childNodes instead of children, childNodes is also more reliable considering browser compatibility issues, more info here:

parent.childNodes.forEach(function (child) {
    console.log(child)
});

or using spread operator:

[...parent.children].forEach(function (child) {
    console.log(child)
});

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

Open Vim, and in normal mode type:

:echo $VIM

In Spark 2.3 you need to just set the --jars option. The file path should be prepended with the scheme though ie file:///<absolute path to the jars> Eg : file:////home/hadoop/spark/externaljsrs/* or file:////home/hadoop/spark/externaljars/abc.jar,file:////home/hadoop/spark/externaljars/def.jar

You have to reset that file to the original state and commit it again using --amend. This is done easiest using git checkout HEAD^.

Prepare demo:

$ git init
$ date >file-a
$ date >file-b
$ git add .
$ git commit -m "Initial commit"
$ date >file-a
$ date >file-b
$ git commit -a -m "the change which should only be file-a"

State before:

$ git show --stat
commit 4aa38f84e04d40a1cb40a5207ccd1a3cb3a4a317 (HEAD -> master)
Date:   Wed Feb 7 17:24:45 2018 +0100

    the change which should only be file-a

 file-a | 2 +-
 file-b | 2 +-
 2 files changed, 2 insertions(+), 2 deletions(-)

Here it comes: restore the previous version

$ git checkout HEAD^ file-b

commit it:

$ git commit --amend file-b
[master 9ef8b8b] the change which should only be file-a
 Date: Wed Feb 7 17:24:45 2018 +0100
 1 file changed, 1 insertion(+), 1 deletion(-)

State after:

$ git show --stat

Date:   Wed Feb 7 17:24:45 2018 +0100

    the change which should only be file-a

If that suits your needs, I would simply use

Application.ScreenUpdating = False

with the added benefit of accelerating your code, instead of slowing it down by using a second instance of Excel.

It's not because you are using alert, it will happen when use document.write() too. This problem generally arises when you name your id or class of any tag as same as any variable which you are using in you javascript code. Try by changing either the javascript variable name or by changing your tag's id/class name.

My code example: bank.html

<!doctype html>
<html>
<head>
    <title>Transaction Tracker</title>
    <script src="bank.js"></script> 
</head>
    <body>
        <div><button onclick="bitch()">Press me!</button></div>
    </body>
</html>

Javascript code: bank.js

function bitch(){ amt = 0;
var a = Math.random(); ran = Math.floor(a * 100);
return ran; }

function all(){
amt = amt + bitch(); document.write(amt + "
"); } setInterval(all,2000);

you can have a look and understand the concept from my code. Here i have used a variable named 'amt' in JS. You just try to run my code. It will work fine but as you put an [id="amt"](without square brackets) (which is a variable name in JS code )for div tag in body of html you will see the same error that you are talking about. So simple solution is to change either the variable name or the id or class name.

typedef void (Dog::*memfun)();
memfun doSomething = &Dog::bark;
....
(pDog->*doSomething)(); // if pDog is a pointer
// (pDog.*doSomething)(); // if pDog is a reference

After replacing the character, you need to be asign to the variable.

var tt = "88,9827";
tt = tt.replace(/,/g, '.')
alert(tt)

In the alert box it will shows 88.9827

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

This is extremely easy to do in Sass! Don't delve into JavaScript for this. The & selector in sass does exactly this.

        });
    });

There are several valid ways already mentioned for locating the php.ini file, but if you came across this page because you want to do something with it in a bash script:

path_php_ini="$(php -i | grep 'Configuration File (php.ini) Path' | grep -oP '(?<=\=\>\s).*')" echo ${path_php_ini}

One con I can think of is if you need really fast access to your data in your view (for example, game animation data like bone positions.) It is very inefficient to keep a layer of separation in this case.

Otherwise, for most other applications which are more data driven than graphics driven, it seems like a logical way to drive a UI.

However, will it automatically remove these committed files from the repository?

No.

The 'best' recipe to do this is using git filter-branch as written about here:

• http://git-scm.com/book/en/Git-Internals-Maintenance-and-Data-Recovery#Removing-Objects

The man page for git-filter-branch contains comprehensive examples.

Note You'll be re-writing history. If you had published any revisions containing the accidentally added files, this could create trouble for users of those public branches. Inform them, or perhaps think about how badly you need to remove the files.

Note In the presence of tags, always use the --tag-name-filter cat option to git filter-branch. It never hurts and will save you the head-ache when you realize later taht you needed it

I had this same problem using the Windows XAMPP 1.7.4 -- after setting a password for mysql, I could no longer access phpMyAdmin. I changed the password in config.inc.php from ' ' to the new mysql password, and changed AllowNoPassword from true to false. I still couldn't log in.

However, I saw that there is also a config.inc.php.safe file, and when I also edited the password settings in THAT file I was subsequently able to log in to phpMyAdmin.

VLC should be able to do this.

The color and window sizing are defined by the shortcut LNK file. I think I found a way that will do what you need, try this:

explorer.exe "Windows PowerShell.lnk"

The LNK file is in the all user start menu which is located in different places depending whether your on XP or Windows 7. In 7 the LNK file is here:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows PowerShell

You can do something like this:

PIE.htc worked for me great (http://css3pie.com/), but with one issue:

You should write absolute path to PIE.htc. It hasn't worked for me when I used relative path.

#include <stdlib.h>

int main()
{
    int x;
    x = rand(6);
    printf("%d", x);
}

Especially as a beginner, you should ask your compiler to print every warning about bad code that it can generate. Modern compilers know lots of different warnings which help you to program better. For example, when you compile this program with the GNU C Compiler:

$ gcc -W -Wall rand.c
rand.c: In function `main':
rand.c:5: error: too many arguments to function `rand'
rand.c:6: warning: implicit declaration of function `printf'

You get two warnings here. The first one says that the rand function only takes zero arguments, not one as you tried. To get a random number between 0 and n, you can use the expression rand() % n, which is not perfect but ok for small n. The resulting random numbers are normally not evenly distributed; smaller values are returned more often.

The second warning tells you that you are calling a function that the compiler doesn't know at that point. You have to tell the compiler by saying #include <stdio.h>. Which include files are needed for which functions is not always simple, but asking the Open Group specification for portable operating systems works in many cases: http://www.google.com/search?q=opengroup+rand.

These two warnings tell you much about the history of the C programming language. 40 years back, the definition of a function didn't include the number of parameters or the types of the parameters. It was also ok to call an unknown function, which in most cases worked. If you want to write code today, you should not rely on these old features but instead enable your compiler's warnings, understand the warnings and then fix them properly.

While a regexp would suit here just fine, I'll present you with an alternative method. It might be a tad faster than the equivalent regexp, but life's all about choices (...or something).

$length = strlen($urlString);
for ($i=0; $i<$length; i++) {
  if ($urlString[$i] === '?') {
    $urlString[$i+1] = '';
    break;
  }
}

Weird, I know.

var text = 'price[5][68]';
var regex = /price\[(\d+)\]\[(\d+)\]/gi;
match = regex.exec(text);

match[1] and match[2] will contain the numbers you're looking for.

   For x = 1 To ActiveWorkbook.Sheets.Count
      'Loop through each of the sheets in the workbook
      'by using x as the sheet index number.
      ActiveWorkbook.Sheets(x).Copy _
         After:=ActiveWorkbook.Sheets(ActiveWorkbook.Sheets.Count)
         'Puts all copies after the last existing sheet.
   Next
End Sub

But the question, can we use it with following code to rename the sheets, if yes, how can we do so?

Sub CreateSheetsFromAList()
Dim MyCell As Range, MyRange As Range
Set MyRange = Sheets("Summary").Range("A10")
Set MyRange = Range(MyRange, MyRange.End(xlDown))
For Each MyCell In MyRange
Sheets.Add After:=Sheets(Sheets.Count) 'creates a new worksheet
Sheets(Sheets.Count).Name = MyCell.Value ' renames the new worksheet
Next MyCell
End Sub

What works for me is that:

• Stopped the ec2 instance
• detach the volume
• attach the volume with the old instance using the same key and was able to SSH
• mount the volume in some temp folder
• checked the file in the directory mount_point/home/ec2-user/.ssh/authorized_keys
  • Ideally, this file needs to have our key information but for me this file was empty
• copied the old instance authorized_keys file to the newly mounted volume
• unmount the device
• reattach to the original ec2 instance
• start it and let it pass the health checks

This time it works for me. But I don't know why it doesn't have my key file information at first when the instance was launched. Check this link too https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#TroubleshootingInstancesConnectingMindTerm

Your array is of byte primitives, but you're trying to call a method on them.

You don't need to do anything explicit to convert a byte to an int, just:

int i=rno[0];

...since it's not a downcast.

Note that the default behavior of byte-to-int conversion is to preserve the sign of the value (remember byte is a signed type in Java). So for instance:

byte b1 = -100;
int i1 = b1;
System.out.println(i1); // -100

If you were thinking of the byte as unsigned (156) rather than signed (-100), as of Java 8 there's Byte.toUnsignedInt:

byte b2 = -100; // Or `= (byte)156;`
int = Byte.toUnsignedInt(b2);
System.out.println(i2); // 156

Prior to Java 8, to get the equivalent value in the int you'd need to mask off the sign bits:

byte b2 = -100; // Or `= (byte)156;`
int i2 = (b2 & 0xFF);
System.out.println(i2); // 156

Just for completeness #1: If you did want to use the various methods of Byte for some reason (you don't need to here), you could use a boxing conversion:

Byte b = rno[0]; // Boxing conversion converts `byte` to `Byte`
int i = b.intValue();

Or the Byte constructor:

Byte b = new Byte(rno[0]);
int i = b.intValue();

But again, you don't need that here.

Just for completeness #2: If it were a downcast (e.g., if you were trying to convert an int to a byte), all you need is a cast:

int i;
byte b;

i = 5;
b = (byte)i;

This assures the compiler that you know it's a downcast, so you don't get the "Possible loss of precision" error.

public static boolean doCollectionsContainSameElements(
        Collection<Integer> c1, Collection<Integer> c2){

    if (c1 == null || c2 == null) {
        return false;
    }
    else if (c1.size() != c2.size()) {
        return false;
    } else {    
        return c1.containsAll(c2) && c2.containsAll(c1);
    }

• sort as requested
• save for int-keys (because of array_replace)
• don't return keys are not existing in inputArray
• (optionally) filter keys no existing in given keyList

Code:

 /**
 * sort keys like in key list
 * filter: remove keys are not listed in keyList
 * ['c'=>'red', 'd'=>'2016-12-29'] = sortAndFilterKeys(['d'=>'2016-12-29', 'c'=>'red', 'a'=>3 ]], ['c', 'd', 'z']){
 *
 * @param array $inputArray
 * @param string[]|int[] $keyList
 * @param bool $removeUnknownKeys
 * @return array
 */
static public function sortAndFilterKeys($inputArray, $keyList, $removeUnknownKeys=true){
    $keysAsKeys = array_flip($keyList);
    $result = array_replace($keysAsKeys, $inputArray); // result = sorted keys + values from input + 
    $result = array_intersect_key($result, $inputArray); // remove keys are not existing in inputArray 
    if( $removeUnknownKeys ){
        $result = array_intersect_key($result, $keysAsKeys); // remove keys are not existing in keyList 
    }
    return $result;
}

You need to add z-index to the divs, with a positive number for the top div and negative for the div below

example

The best and tested solution is to put the following small snippet which will collapse the accordion tab which is already open when you load. In my case the last sixth tab was open so I made it collapsed on page load.

 $(document).ready(){
      $('#collapseSix').collapse("hide");
 }

I solved this by uninstalling and then re-installing the dnspython module with PIP.

$ pip uninstall dnspython

After the long list of files within pycache, type y to continue with the uninstall. After complete type:

$ pip install dnspython

I then ran my script and the errors were resolved.

Mostly for my own reference, here's how you get it from a private key generated by ssh-keygen

openssl rsa -text -noout -in ~/.ssh/id_rsa

Of course, this only works with the private key.

We can export a jar file for Android library project without resource files by Android studio. It is also requirement what I met recently.

1. Config your build.gradle file

    // Task to delete old jar

    task clearJar(type: Delete){
       delete 'release/lunademo.jar'
    }

    // task to export contents as jar
    task makeJar(type: Copy) {
       from ('build/intermediates/bundles/release/')
       into ('build/libs/')
       include ('classes.jar')
       rename('classes.jar', 'lunademo.jar')
    }
    makeJar.dependsOn(clearJar, build)

2. Run gradlew makeJar under your project root

You will see your libs under dir as build/libs/ if you are luckily.

============================================================

If you met issue as "Socket timeout exception" on command line as below,

You can follow this steps to open Gradle window in the right part and click "makeJar" on Android studio like this,

Then go to build/libs dir, you will see your jar file.

Hope that it is helpful for u.

Good Luck @.@

RobW's way worked great for me. For people using jQuery here's a simplified version that I ended up using:

var iframe = $(video_player_div).find('iframe');

var src = $(iframe).attr('src');      

$(iframe).attr('src', '').attr('src', src);

In this example "video_player" is a parent div containing the iframe.

1st -- go get will refuse to authenticate on the command line. So you need to cache the credentials in git. Because I use osx I can use osxkeychain credential helper.

2nd For me, I have 2FA enabled and thus could not use my password to auth. Instead I had to generate a personal access token to use in place of the password.

1. setup osxkeychain credential helper https://help.github.com/articles/caching-your-github-password-in-git/
2. If using TFA instead of using your password, generate a personal access token with repo scope https://github.com/settings/tokens
3. git clone a private repo just to make it cache the password git clone https://github.com/user/private_repo and used your github.com username for username and the generated personal access token for password.

4. Removed the just cloned repo and retest to ensure creds were cached -- git clone https://github.com/user/private_repo and this time wasnt asked for creds.

   5. go get will work with any repos that the personal access token can access. You may have to repeat the steps with other accounts / tokens as permissions vary.

A GUID is a 16-byte (128-bit) number, typically represented by a 32-character hexadecimal string. A GUID (in hex form) need not contain any alpha characters, though by chance it probably would. If you are targeting a GUID in hex form, you can check that the string is 32-characters long (after stripping dashes and curly brackets) and has only letters A-F and numbers.

There is certain style of presenting GUIDs (dash-placement) and regular expressions can be used to check for this, e.g.,

@"^(\{{0,1}([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}\}{0,1})$"

from http://www.geekzilla.co.uk/view8AD536EF-BC0D-427F-9F15-3A1BC663848E.htm. That said, it should be emphasized that the GUID really is a 128-bit number and could be represented in a number of different ways.

Residuum did provide a correct answer to how you should get shell exec to find your script, but in regards to security, there are a couple of points.

I would imagine you don't want your shell script to be in your web root, as it would be visible to anyone with web access to your server.

I would recommend moving the shell script to outside of the webroot

    <?php
      $tempFolder = '/tmp';
      $webRootFolder = '/var/www';
      $scriptName = 'myscript.sh';
      $moveCommand = "mv $webRootFolder/$scriptName $tempFolder/$scriptName";
      $output = shell_exec($moveCommand);
    ?>

In regards to the:

i added www-data ALL=(ALL) NOPASSWD:ALL to /etc/sudoers works

You can modify this to only cover the specific commands in your script which require sudo. Otherwise, if none of the commands in your sh script require sudo to execute, you don't need to do this at all anyway.

Try running the script as the apache user (use the su command to switch to the apache user) and if you are not prompted for sudo or given permission denied, etc, it'll be fine.

ie:

sudo su apache (or www-data)
cd /var/www
sh ./myscript

Also... what brought me here was that I wanted to run a multi line shell script using commands that are dynamically generated. I wanted all of my commands to run in the same shell, which won't happen using multiple calls to shell_exec(). The answer to that one is to do it like Jenkins - create your dynamically generated multi line of commands, put it in a variable, save it to a file in a temp folder, execute that file (using shell_exec in() php as Jenkins is Java), then do whatever you want with the output, and delete the temp file

... voila

You can use setTimeout():

var addBg = function(e) {_x000D_
  e = e || window.event;_x000D_
  e.preventDefault();_x000D_
  var el = e.target || e.srcElement;_x000D_
  el.className = 'bg';_x000D_
  setTimeout(function() {_x000D_
    removeBg(el);_x000D_
  }, 10 * 1000); //<-- (in miliseconds)_x000D_
};_x000D_
_x000D_
var removeBg = function(el) {_x000D_
  el.className = '';_x000D_
};

div {_x000D_
  border: 1px solid grey;_x000D_
  padding: 5px 7px;_x000D_
  display: inline-block;_x000D_
  margin: 5px;_x000D_
}_x000D_
.bg {_x000D_
  background: orange;_x000D_
}

<body onclick='addBg(event);'>This is body_x000D_
  <br/>_x000D_
  <div onclick='addBg(event);'>This is div_x000D_
  </div>_x000D_
</body>

Using jQuery:

var addBg = function(e) {_x000D_
  e.stopPropagation();_x000D_
  var el = $(this);_x000D_
  el.addClass('bg');_x000D_
  setTimeout(function() {_x000D_
    removeBg(el);_x000D_
  }, 10 * 1000); //<-- (in miliseconds)_x000D_
};_x000D_
_x000D_
var removeBg = function(el) {_x000D_
  $(el).removeClass('bg');_x000D_
};_x000D_
_x000D_
$(function() {_x000D_
  $('body, div').on('click', addBg);_x000D_
});

div {_x000D_
  border: 1px solid grey;_x000D_
  padding: 5px 7px;_x000D_
  display: inline-block;_x000D_
  margin: 5px;_x000D_

Here's what I'm doing me, which is simpler to remove the title of back button

override func viewDidLoad() {
    super.viewDidLoad()
    navigationController?.navigationBar?.backItem?.title = ""
}

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

you need to take out the quotes:

soda = a + b

(You want to refer to the variables a and b, not the strings "a" and "b")

Unfortunately none of the above worked for me, so instead I added a label on top of the comboxbox that says "Please select". I used the following code to show and hide it:

1. When I initialise my combobox, if there is no selected value I bring it to the front and set the text:

   PleaseSelectValueLabel.BringToFront();
   PleaseSelectValueLabel.Text = Constants.AssessmentValuePrompt;
   

2. If there is a value selected I send it to the back:

   PleaseSelectValueLabel.SendToBack();
   

3. I then use the following events to move the label to the front or back depending on whether the user has selected a value:

   private void PleaseSelectValueLabel_Click(object sender, EventArgs e)
   {
       PleaseSelectValueLabel.SendToBack();
       AssessmentValue.Focus();
   }
   
   private void AssessmentValue_Click(object sender, EventArgs e)
   {
       PleaseSelectValueLabel.SendToBack();
   }
   
   //if the user hasnt selected an item, make the please select label visible again
   private void AssessmentValue_Leave(object sender, EventArgs e)
   {
       if (AssessmentValue.SelectedIndex < 0)
       {
           PleaseSelectValueLabel.BringToFront();
       }
   }
   

I had the same problem, because as soon as display: x; is in animation, it won't animate.

I ended up in creating custom keyframes, first changing the display value then the other values. May give a better solution.

Or, instead of using display: none; use position: absolute; visibility: hidden; It should work.

I had a directory of files that I wanted to check. I created an Excel macro to determine ANSI vs. UTF-8. This worked for me.

        Sub GetTextFileEncoding()
        Dim sFile As String
        Dim sPath As String
        Dim sTextLine As String
        Dim iRow As Integer

        'Set Defaults and Initial Values
        iRow = 1
        sPath = "C:textfiles\"
        sFile = Dir(sPath & "*.txt")

        Do While Len(sFile) > 0
            'Get FileType
            'Debug.Print sFile & " - " & FileEncodeType(sPath & sFile)

            'Show on Excel Worksheet
            Cells(iRow, 1).Value = sFile
            Cells(iRow, 2).Value = FileEncodeType(sPath & sFile)

            'Get next file
            sFile = Dir

            'Increment Row
            iRow = iRow + 1
        Loop
    End Sub

    Function FileEncodeType(sFile As String) As String
        Dim bEF As Boolean
        Dim bBB As Boolean
        Dim bBF As Boolean

        bEF = False
        bBB = False
        bBF = False

        Open sFile For Input As #1
            If Not EOF(1) Then
                'Read first line
                Line Input #1, textline
                'Debug.Print textline
                For i = 1 To 3
                    'Debug.Print Asc(Mid(textline, i, 1)) & " - " & Mid(textline, i, 1)
                    Select Case i
                        Case 1
                            If Asc(Mid(textline, i, 1)) = 239 Then
                                bEF = True
                            End If
                        Case 2
                             If Asc(Mid(textline, i, 1)) = 187 Then
                                bBB = True
                            End If
                        Case 3
                             If Asc(Mid(textline, i, 1)) = 191 Then
                                bBF = True
                            End If
                        Case 4

                    End Select
                Next
            End If
        Close #1

        If bEF And bBB And bBF Then
            FileEncodeType = "UTF-8"
        Else
            FileEncodeType = "ANSI"
        End If
    End Function

The difference is that in the first case the retrieved user is not tracked by the context so when you are going to save the user back to database you must attach it and set correctly state of the user so that EF knows that it should update existing user instead of inserting a new one. In the second case you don't need to do that if you load and save the user with the same context instance because the tracking mechanism handles that for you.

Its really working if we use Doctype on our web page jquery(window) will return the viewport height else it will return the complete document height.

Define the following tag on the top of your web page: <!DOCTYPE html>

I hope this will help. For details on how this code work you can check here

Note: this answer is only valid for git v1.8 and older.

Most of this has been said in the other answers and comments, but here's a concise explanation:

• git fetch fetches all branch heads (or all specified by the remote.fetch config option), all commits necessary for them, and all tags which are reachable from these branches. In most cases, all tags are reachable in this way.
• git fetch --tags fetches all tags, all commits necessary for them. It will not update branch heads, even if they are reachable from the tags which were fetched.

Summary: If you really want to be totally up to date, using only fetch, you must do both.

It's also not "twice as slow" unless you mean in terms of typing on the command-line, in which case aliases solve your problem. There is essentially no overhead in making the two requests, since they are asking for different information.

Invoking of validation on form element could be handled by triggering change event on this element:

a) exemple: trigger change on separated element in form

$scope.formName.elementName.$$element.change();

b) exemple: trigger change event for each of form elements for example on ng-submit, ng-click, ng-blur ...

vm.triggerChangeForFormElements = function() {
    // trigger change event for each of form elements
    angular.forEach($scope.formName, function (element, name) {
        if (!name.startsWith('$')) {
            element.$$element.change();
        }
    });
};

c) and one more way for that

    var handdleChange = function(form){
        var formFields = angular.element(form)[0].$$controls;
        angular.forEach(formFields, function(field){
            field.$$element.change();
        });
    };

If I understand your issue this should work

&emsp—the em space; this should be a very wide space, typically as much as four real spaces. &ensp—the en space; this should be a somewhat wide space, roughly two regular spaces. &thinsp—this will be a narrow space, even more narrow than a regular space.

public class FooBar {

You need to write the Class Name for the search.
from FooBar

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

From the Android documentation:

The CookieSyncManager is used to synchronize the browser cookie store between RAM and permanent storage. To get the best performance, browser cookies are saved in RAM. A separate thread saves the cookies between, driven by a timer.

To use the CookieSyncManager, the host application has to call the following when the application starts:

CookieSyncManager.createInstance(context)

To set up for sync, the host application has to call

CookieSyncManager.getInstance().startSync()

in Activity.onResume(), and call

 CookieSyncManager.getInstance().stopSync()

in Activity.onPause().

To get instant sync instead of waiting for the timer to trigger, the host can call

CookieSyncManager.getInstance().sync()

The sync interval is 5 minutes, so you will want to force syncs manually anyway, for instance in onPageFinished(WebView, String). Note that even sync() happens asynchronously, so don't do it just as your activity is shutting down.

Finally something like this should work:

// use cookies to remember a logged in status   
CookieSyncManager.createInstance(this);
CookieSyncManager.getInstance().startSync();
WebView webview = new WebView(this);
webview.getSettings().setJavaScriptEnabled(true);
setContentView(webview);      
webview.loadUrl([MY URL]);

When calling a function, the word "this" is a reference to the object that called the function.

In your example, it is a reference to the anchor element. At the other end, the function call then access member variables of the element through the parameter that was passed.

I needed to implement this in PowerShell, hope it can help someone else. Some notes about this method

1. Don't split any of the lines or the calculation will be wrong
2. To calculate in KM remove the * 1000 in the calculation of $distance
3. Change $earthsRadius = 3963.19059 and remove * 1000 in the calculation of $distance the to calulate the distance in miles

4. I'm using Haversine, as other posts have pointed out Vincenty's formulae is much more accurate

   Function MetresDistanceBetweenTwoGPSCoordinates($latitude1, $longitude1, $latitude2, $longitude2)  
   {  
     $Rad = ([math]::PI / 180);  
   
     $earthsRadius = 6378.1370 # Earth's Radius in KM  
     $dLat = ($latitude2 - $latitude1) * $Rad  
     $dLon = ($longitude2 - $longitude1) * $Rad  
     $latitude1 = $latitude1 * $Rad  
     $latitude2 = $latitude2 * $Rad  
   
     $a = [math]::Sin($dLat / 2) * [math]::Sin($dLat / 2) + [math]::Sin($dLon / 2) * [math]::Sin($dLon / 2) * [math]::Cos($latitude1) * [math]::Cos($latitude2)  
     $c = 2 * [math]::ATan2([math]::Sqrt($a), [math]::Sqrt(1-$a))  
   
     $distance = [math]::Round($earthsRadius * $c * 1000, 0) #Multiple by 1000 to get metres  
   
     Return $distance  
   }
   

As mentioned on a Atlassian blog page, generate a config file within the .ssh folder, including the following text:

#user1 account
 Host bitbucket.org-user1
     HostName bitbucket.org
     User git
     IdentityFile ~/.ssh/user1
     IdentitiesOnly yes

 #user2 account
 Host bitbucket.org-user2
     HostName bitbucket.org
     User git
     IdentityFile ~/.ssh/user2
     IdentitiesOnly yes

Then you can simply checkout with the suffix domain and within the projects you can configure the author names, etc. locally.

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

The constraints in the top-voted answer here worked for me, and I've pasted an image of the constraints below, as created in my storyboard.

I did hit two issues though that others should be aware of:

1. After adding constraints similar to those in in the accepted answer, I'd get the red autolayout error Need constraints for: X position or width. This was solved by adding a UILabel as a subview of the stack view.

   I'm adding the subviews programmatically, so I originally had no subviews on the storyboard. To get rid of the autolayout errors, add a subview to the storyboard, then remove it on load before adding your real subviews and constraints.

2. I originally attempted to add UIButtons to the UIStackView. The buttons and views would load, but the scroll view would not scroll. This was solved by adding UILabels to the Stack View instead of buttons. Using the same constraints, this view hierarchy with the UILabels scrolls but the UIButtons does not.

   I'm confused by this issue, as the UIButtons do seem to have an IntrinsicContentSize (used by the Stack View). If anyone knows why the buttons don't work, I'd love to know why.

Here is my view hierarchy and constraints, for reference:

TempData in Asp.Net MVC is one of the very useful feature. It is used to pass data from current request to subsequent request. In other words if we want to send data from one page to another page while redirection occurs, we can use TempData, but we need to do some consideration in code to achieve this feature in MVC. Because the life of TempData is very short and lies only till the target view is fully loaded. But, we can use Keep() method to persist data in TempData.

In your Startup.Auth.cs file add this line:

LoginPath = new PathString("/Account/Login"),

Example:

// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
    LoginPath = new PathString("/Account/Login"),
    Provider = new CookieAuthenticationProvider
    {
        // Enables the application to validate the security stamp when the user logs in.
        // This is a security feature which is used when you change a password or add an external login to your account.  
        OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
        validateInterval: TimeSpan.FromMinutes(30),
        regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
    }
});

You can use #stringify from query string

import { stringify } from 'query-string';

fetch(`https://example.org?${stringify(params)}`)

This one looks a bit nicer:

var rgb = $('#selector').css('backgroundColor').match(/\d+/g);
var r   = parseInt(rgb[0], 10);
var g   = parseInt(rgb[1], 10);
var b   = parseInt(rgb[2], 10);
var hex = '#'+ r.toString(16) + g.toString(16) + b.toString(16);

a more succinct one-liner:

var rgb = $('#selector').css('backgroundColor').match(/\d+/g);
var hex = '#'+ Number(rgb[0]).toString(16) + Number(rgb[1]).toString(16) + Number(rgb[2]).toString(16);

forcing jQuery to always return hex:

$.cssHooks.backgroundColor = {
    get: function(elem) {
        if (elem.currentStyle)
            var bg = elem.currentStyle["backgroundColor"];
        else if (window.getComputedStyle) {
            var bg = document.defaultView.getComputedStyle(elem,
                null).getPropertyValue("background-color");
        }
        if (bg.search("rgb") == -1) {
            return bg;
        } else {
            bg = bg.match(/\d+/g);
            function hex(x) {
                return ("0" + parseInt(x).toString(16)).slice(-2);
            }
            return "#" + hex(bg[0]) + hex(bg[1]) + hex(bg[2]);
        }
    }
}

You can think of Python global variables as "module" variables - and as such they are much more useful than the traditional "global variables" from C.

A global variable is actually defined in a module's __dict__ and can be accessed from outside that module as a module attribute.

So, in your example:

# ../myproject/main.py

# Define global myList
# global myList  - there is no "global" declaration at module level. Just inside
# function and methods
myList = []

# Imports
import subfile

# Do something
subfile.stuff()
print(myList[0])

And:

# ../myproject/subfile.py

# Save "hey" into myList
def stuff():
     # You have to make the module main available for the 
     # code here.
     # Placing the import inside the function body will
     # usually avoid import cycles - 
     # unless you happen to call this function from 
     # either main or subfile's body (i.e. not from inside a function or method)
     import main
     main.mylist.append("hey")

Be sure to configure the 'default' key in app/config/database.php

For postgres, this would be 'default' => 'postgres',

If you are receiving a [PDOException] could not find driver error, check to see if you have the correct PHP extensions installed. You need pdo_pgsql.so and pgsql.so installed and enabled. Instructions on how to do this vary between operating systems.

For Windows, the pgsql extensions should come pre-downloaded with the official PHP distribution. Just edit your php.ini and uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so

Also, in php.ini, make sure extension_dir is set to the proper directory. It should be a folder called extensions or ext or similar inside your PHP install directory.

Finally, copy libpq.dll from C:\wamp\bin\php\php5.*\ into C:\wamp\bin\apache*\bin and restart all services through the WampServer interface.

If you still get the exception, you may need to add the postgres \bin directory to your PATH:

1. System Properties -> Advanced tab -> Environment Variables
2. In 'System variables' group on lower half of window, scroll through and find the PATH entry.
3. Select it and click Edit
4. At the end of the existing entry, put the full path to your postgres bin directory. The bin folder should be located in the root of your postgres installation directory.
5. Restart any open command prompts, or to be certain, restart your computer.

This should hopefully resolve any problems. For more information see:

• http://php.net/manual/en/install.pecl.windows.php
• http://webcheatsheet.com/php/install_and_configure.php#extsetup

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

Edit: Here's a working ultra-minimalistic file sender and receiver. Make sure you understand what the code is doing on both sides.

Open up your git bash and type

echo $HOME

This shall be the same folder as you get when you open your command window (cmd) and type

echo %USERPROFILE%

And – of course – the .ssh folder shall be present on THAT directory.

If I understand what you're trying to do correctly, then I don't think this is possible with CSS while keeping the children absolutely positioned.

Absolutely positioned elements are completely removed from the document flow, and thus their dimensions cannot alter the dimensions of their parents.

If you really had to achieve this affect while keeping the children as position: absolute, you could do so with JavaScript by finding the height of the absolutely positioned children after they have rendered, and using that to set the height of the parent.

Alternatively, just use float: left/float:right and margins to get the same positioning effect while keeping the children in the document flow, you can then use overflow: hidden on the parent (or any other clearfix technique) to cause its height to expand to that of its children.

article {
    position: relative;
    overflow: hidden;
}

.one {
    position: relative;
    float: left;
    margin-top: 10px;
    margin-left: 10px;
    background: red;
    width: 30px;
    height: 30px;
}

.two {
    position: relative;
    float: right;
    margin-top: 10px;
    margin-right: 10px;
    background: blue;
    width: 30px;
    height: 30px;
}

Maybe this

$products = $art->products->take($limit)->skip($offset)->get();

I had this problem today. I'm using systemjs to load the dependencies.

I was loading the Rxjs like this:

...
    paths: {
        "rxjs/*": "node_modules/rxjs/bundles/Rx.umd.min.js"
    },
...

Instead of use paths use this:

var map = {
...
'rxjs':                       'node_modules/rxjs',
...
}

var packages = {
...
'rxjs': { main: 'bundles/Rx.umd.min.js', defaultExtension: 'js' }
...
}

This little change in the way systemjs loads the library fixed my problem.

I think the documentation is reasonably helpful!

If you read it again, it says that adding open graph elements on your website will make your website act as a facebook page and you'll get the ability to publish updates to them etc.

So I think it's up to you - you can either just have a page with no OG elements, which is less work but also less 'rewarding' for you.

If you do use og, then set type to: blog

Finally: fb:admins or fb:app_id - A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.

So just put your own fbid in there. As a tip, you can easily get this by looking at the url of your profile photo on facebook.

find <directory_path>  -type f -name "<wildcard-match>"

In the wildcard-match you can provide the string you wish to match e.g. *.c (for all c files)

The below seems to work for me.

using System;
using System.Reflection;

public class ReflectStatic
{
    private static int SomeNumber {get; set;}
    public static object SomeReference {get; set;}
    static ReflectStatic()
    {
        SomeReference = new object();
        Console.WriteLine(SomeReference.GetHashCode());
    }
}

public class Program
{
    public static void Main()
    {
        var rs = new ReflectStatic();
        var pi = rs.GetType().GetProperty("SomeReference",  BindingFlags.Static | BindingFlags.Public);
        if(pi == null) { Console.WriteLine("Null!"); Environment.Exit(0);}
        Console.WriteLine(pi.GetValue(rs, null).GetHashCode());


    }
}

I think this may be useful for those who would like attribute's value to be a function:

import { RNCamera } from 'react-native-camera';
[...]

export default class MyView extends React.Component {

    _myFunction = (myObject) => {
        console.log(myObject.type); //
    }

    render() {

        var scannerProps = Platform.OS === 'ios' ? 
        {
            onBarCodeRead : this._myFunction
        } 
        : 
        { 
            // here you can add attribute(s) for other platforms
        }

        return (
            // it is just a part of code for MyView's layout
            <RNCamera 
                ref={ref => { this.camera = ref; }}
                style={{ flex: 1, justifyContent: 'flex-end', alignItems: 'center', }}
                type={RNCamera.Constants.Type.back}
                flashMode={RNCamera.Constants.FlashMode.on}
                {...scannerProps}
            />
        );
    }
}

All you need is to make an ajax request to your pythoncode. You can do this with jquery http://api.jquery.com/jQuery.ajax/, or use just javascript

$.ajax({
  type: "POST",
  url: "~/pythoncode.py",
  data: { param: text}
}).done(function( o ) {
   // do something
});

l = [15, 18, 2, 36, 12, 78, 5, 6, 9]
sum(l) / len(l)

Here is a good article on creating and adding a class library. Even shows how to create Methods through the method wizard and how to use it in the application

You will need to define the repository outside of buildscript. The buildscript configuration block only sets up the repositories and dependencies for the classpath of your build script but not your application.

I ran into this problem with my new Nexus 4 and an APK built with Adobe AIR. I already had android:installLocation="preferExternal" in my manifest. I noticed I was also calling adb install with the -s option (Install package on the shared mass storage such as sdcard.) which seemed like overkill.

Removing the -s flag from adb install fixed the issue for me.

Just from reading that i would have never understood that "$@" expands into a list of separate parameters. Whereas, "$*" is one parameter consisting of all the parameters added together.

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

None of the existing answers worked for me. Having all the correct update sites in "available sites" was not enough to tell Eclipse how to find its dependencies.

Using Fedora 14 and Eclipse Indigo 3.7.1, I had to follow these steps to make the installation working:

1. Check and install "Linux Tools" from http://download.eclipse.org/releases/indigo
2. Check and install "Linux Tools" from http://download.eclipse.org/releases/indigo/201109230900

After restarting Eclipse, I was able to finaly install the Android SDK.

You can use closures to pass parameters:

iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);

However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):

document.getElementById("myFrame").contentDocument.addEventListener(...);

For loop is not officially supported yet by SQL server. Already there is answer on achieving FOR Loop's different ways. I am detailing answer on ways to achieve different types of loops in SQL server.

FOR Loop

DECLARE @cnt INT = 0;

WHILE @cnt < 10
BEGIN
   PRINT 'Inside FOR LOOP';
   SET @cnt = @cnt + 1;
END;

PRINT 'Done FOR LOOP';

If you know, you need to complete first iteration of loop anyway, then you can try DO..WHILE or REPEAT..UNTIL version of SQL server.

DO..WHILE Loop

DECLARE @X INT=1;

WAY:  --> Here the  DO statement

  PRINT @X;

  SET @X += 1;

IF @X<=10 GOTO WAY;

REPEAT..UNTIL Loop

DECLARE @X INT = 1;

WAY:  -- Here the REPEAT statement

  PRINT @X;

  SET @X += 1;

IFNOT(@X > 10) GOTO WAY;

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

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

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

iex $cmd1

parseInt will throw NumberFormatException if it cannot parse the integer. So doing this will answer your question

try{
Integer.parseInt(....)
}catch(NumberFormatException e){
//couldn't parse
}

[Hg Tortoise 4.6.1] If it's recent action, you can use "Rollback/Undo" action (Ctrl+U).

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

To add a row:

DataRow row = dt.NewRow();
row["Name"] = "Ravi";
row["Marks"] = 500;
dt.Rows.Add(row);

If i understand your question, you just want to be able to access items in a data frame (or list) by row:

x = matrix( ceiling(9*runif(20)), nrow=5  )   
colnames(x) = c("col1", "col2", "col3", "col4")
df = data.frame(x)      # create a small data frame

df[1,]                  # get the first row
df[3,]                  # get the third row
df[nrow(df),]           # get the last row

lf = as.list(df)        

lf[[1]]                 # get first row
lf[[3]]                 # get third row

etc.

I've lifted this from http://www.mail-archive.com/[email protected]/msg02716.html which is an explanation I wrote several years ago.

I'll use JavaScript in this example, but many other languages will work as well.

Our goal is to be able to write a recursive function of 1 variable using only functions of 1 variables and no assignments, defining things by name, etc. (Why this is our goal is another question, let's just take this as the challenge that we're given.) Seems impossible, huh? As an example, let's implement factorial.

Well step 1 is to say that we could do this easily if we cheated a little. Using functions of 2 variables and assignment we can at least avoid having to use assignment to set up the recursion.

// Here's the function that we want to recurse.
X = function (recurse, n) {
  if (0 == n)
    return 1;
  else
    return n * recurse(recurse, n - 1);
};

// This will get X to recurse.
Y = function (builder, n) {
  return builder(builder, n);
};

// Here it is in action.
Y(
  X,
  5
);

Now let's see if we can cheat less. Well firstly we're using assignment, but we don't need to. We can just write X and Y inline.

// No assignment this time.
function (builder, n) {
  return builder(builder, n);
}(
  function (recurse, n) {
    if (0 == n)
      return 1;
    else
      return n * recurse(recurse, n - 1);
  },
  5
);

But we're using functions of 2 variables to get a function of 1 variable. Can we fix that? Well a smart guy by the name of Haskell Curry has a neat trick, if you have good higher order functions then you only need functions of 1 variable. The proof is that you can get from functions of 2 (or more in the general case) variables to 1 variable with a purely mechanical text transformation like this:

// Original
F = function (i, j) {
  ...
};
F(i,j);

// Transformed
F = function (i) { return function (j) {
  ...
}};
F(i)(j);

where ... remains exactly the same. (This trick is called "currying" after its inventor. The language Haskell is also named for Haskell Curry. File that under useless trivia.) Now just apply this transformation everywhere and we get our final version.

// The dreaded Y-combinator in action!
function (builder) { return function (n) {
  return builder(builder)(n);
}}(
  function (recurse) { return function (n) {
    if (0 == n)
      return 1;
    else
      return n * recurse(recurse)(n - 1);
  }})(
  5
);

Feel free to try it. alert() that return, tie it to a button, whatever. That code calculates factorials, recursively, without using assignment, declarations, or functions of 2 variables. (But trying to trace how it works is likely to make your head spin. And handing it, without the derivation, just slightly reformatted will result in code that is sure to baffle and confuse.)

You can replace the 4 lines that recursively define factorial with any other recursive function that you want.

+1 Database

Forms in your app can even re-translate themselves on the fly if corrections are made to the database.

We used a system where all the controls were mapped in an XML file (one per form) to language resource IDs, but all the IDs were in the database.

Basically, instead of having each control hold the ID (implementing an interface, or using the tag property in VB6), we used the fact that in .NET, the control tree was easily discoverable through reflection. A process when the form loaded would build the XML file if it was missing. The XML file would map the controls to their resource IDs, so this simply needed to be filled in and mapped to the database. This meant that there was no need to change the compiled binary if something was not tagged, or if it needed to be split to another ID (some words in English which might be used as both nouns and verbs might need to translate to two different words in the dictionary and not be re-used, but you might not discover this during initial assignment of IDs). But the fact is that the whole translation process becomes completely independent of your binary (every form has to inherit from a base form which knows how to translate itself and all its controls).

The only ones where the app gets more involved is when a phase with insertion points is used.

The database translation software was your basic CRUD maintenance screen with various workflow options to facilitate going through the missing translations, etc.

If you are extending from an AppCompatActivity and are trying to get the ActionBar from the Fragment, you can do this:

ActionBar mActionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();

Embarrassingly, the problem in my case is that I haven't rebuilt the code after adding the controller.

So maybe the first thing to check is that your controller was built and is present (and public) in the binaries. It might save you few minutes of debugging if you're like me.

For me it was on line 183, but it only works after you reboot your computer. I wish there was a way to quickly change it without having to reboot each time, but for now that's the only way I know how.

To match pattern or an empty string, use

^$|pattern

Explanation

• ^ and $ are the beginning and end of the string anchors respectively.
• | is used to denote alternates, e.g. this|that.

References

• regular-expressions.info/Anchors and Alternation

On \b

\b in most flavor is a "word boundary" anchor. It is a zero-width match, i.e. an empty string, but it only matches those strings at very specific places, namely at the boundaries of a word.

That is, \b is located:

• Between consecutive \w and \W (either order):
  • i.e. between a word character and a non-word character
• Between ^ and \w
  • i.e. at the beginning of the string if it starts with \w
• Between \w and $
  • i.e. at the end of the string if it ends with \w

After you've run the Inspect by Name, select all the locations, and make use of the Apply quick fixes to all the problems drop-down, and use either (or both) of Delete unused parameter(s) and Safe Delete.

Don't forget to hit Do Refactor afterwards.

Then you'll need to run another analysis, as the refactored code will no doubt reveal more unused declarations.

I normally use another way to do the same

A simple way to enable to receive "text/plain" content type:

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];

Similarly if you wish to enable "text/html" content type:

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

Currency pipe uses the number one internally for number formatting. So you can use it like this:

I have detected something different from the other answers. Reaching this exception in my project was the result of a corrupt compilation. Without making any changes, just forcing rebuild, it was fixed.

The parameters of isset() should be separated by a comma sign (,) and not a dot sign (.). Your current code concatenates the variables into a single parameter, instead of passing them as separate parameters.

So the original code evaluates the variables as a unified string value:

isset($_POST['search_term'] . $_POST['postcode']) // Incorrect

While the correct form evaluates them separately as variables:

isset($_POST['search_term'], $_POST['postcode']) // Correct

If you want to give your user all read permissions, you could use:

EXEC sp_addrolemember N'db_datareader', N'your-user-name'

That adds the default db_datareader role (read permission on all tables) to that user.

There's also a db_datawriter role - which gives your user all WRITE permissions (INSERT, UPDATE, DELETE) on all tables:

EXEC sp_addrolemember N'db_datawriter', N'your-user-name'

If you need to be more granular, you can use the GRANT command:

GRANT SELECT, INSERT, UPDATE ON dbo.YourTable TO YourUserName
GRANT SELECT, INSERT ON dbo.YourTable2 TO YourUserName
GRANT SELECT, DELETE ON dbo.YourTable3 TO YourUserName

and so forth - you can granularly give SELECT, INSERT, UPDATE, DELETE permission on specific tables.

This is all very well documented in the MSDN Books Online for SQL Server.

And yes, you can also do it graphically - in SSMS, go to your database, then Security > Users, right-click on that user you want to give permissions to, then Properties adn at the bottom you see "Database role memberships" where you can add the user to db roles.

Use a computed column instead. It is almost always a better idea to use a computed column than a trigger.

See Example below of a computed column using the UPPER function:

create table #temp (test varchar (10), test2 AS upper(test))
insert #temp (test)
values ('test')
select * from #temp

And not to sound like a broken record or anything, but this is critically important. Never write a trigger that will not work correctly on multiple record inserts/updates/deletes. This is an extremely poor practice as sooner or later one of these will happen and your trigger will cause data integrity problems asw it won't fail precisely it will only run the process on one of the records. This can go a long time until someone discovers the mess and by themn it is often impossible to correctly fix the data.

  $("#form-field").val("5").trigger("change");

If javacpl does not open and gives you Could not find the main class:, it could be that Java is confused because of changes in deployment.properties (can be found in C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment on Win7). Delete that file and everything's fine.

This bug seems to be 6 years old, cf. An app should be able to ignore properties that have become obsolete over time, shouldn't it?

private String removeScript(String content) {
    Pattern p = Pattern.compile("<script[^>]*>(.*?)</script>",
            Pattern.DOTALL | Pattern.CASE_INSENSITIVE);
    return p.matcher(content).replaceAll("");
}

This is borderline programming, but look into using tr:

$ echo "this is just a test" | tr -s ' ' | tr ' ' '_'

Should do it. The first invocation squeezes the spaces down, the second replaces with underscore. You probably need to add TABs and other whitespace characters, this is for spaces only.

If you are looking to create an instant messenger for Android, this code should get you started somewhere.

Excerpt from the source :

This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.

EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.

There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!

*UPDATE : * Scringo services will be closed down on 15 February, 2015.

FOR ANGULAR 7+

Actually since Angular 7.2 there is not need to use a service for saving the previous url. You could just use the state object to set the last url before linking to the login page. Here is an example for a login scenario.

@Component({ ... })
class SomePageComponent {
  constructor(private router: Router) {}

  checkLogin() {
    if (!this.auth.loggedIn()) {
      this.router.navigate(['login'], { state: { redirect: this.router.url } });
    }
  }
}

@Component({...})
class LoginComponent {
  constructor(private router: Router) {}

  backToPreviousPage() {
    const { redirect } = window.history.state;

    this.router.navigateByUrl(redirect || '/homepage');
  }
}

Additionally you could also pass the data in the template:

@Component({
  template: '<a routerLink="/some-route" [state]="{ redirect: router.url}">Go to some route</a>'
})
class SomePageComponent {
  constructor(public router: Router) {}
}

This is the shared preferences code i use successfully, Refer this link:

  public class MainActivity extends Activity {

private static final int RESULT_SETTINGS = 1;
Button button;
public String a="dd";

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

 button = (Button) findViewById(R.id.btnoptions);


setContentView(R.layout.activity_main);

  // showUserSettings();
  }

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.settings, menu);
return true;
 }

@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {

case R.id.menu_settings:
 Intent i = new Intent(this, UserSettingActivity.class);
 startActivityForResult(i, RESULT_SETTINGS);
 break;

 }

return true;
}

@Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data)     {
  super.onActivityResult(requestCode, resultCode, data);

 switch (requestCode) {
 case RESULT_SETTINGS:
 showUserSettings();
 break;

 } 

  }

  private void showUserSettings() {
 SharedPreferences sharedPrefs = PreferenceManager
.getDefaultSharedPreferences(this);

 StringBuilder builder = new StringBuilder();

 builder.append("\n Pet: "
  + sharedPrefs.getString("prefpetname", "NULL"));

 builder.append("\n Address:"
 + sharedPrefs.getString("prefaddress","NULL" ));

 builder.append("\n Your name: "
 + sharedPrefs.getString("prefname", "NULL"));

 TextView settingsTextView = (TextView) findViewById(R.id.textUserSettings);


  settingsTextView.setText(builder.toString());


    }

   }

HAPPY CODING!

Try explicitly enumerating the results by calling ToList().

Change

foreach (var item in query)

to

foreach (var item in query.ToList())

Look at the getFragmentManager().popBackStack() methods (there are several to choose from)

I just met and solved this problem by myself. My problem is a little different. I'm using visual studio on Windows 10. When I create the project, the Target Platform Version was automatically set to 10.0.15063.0. But there is no kernel32.lib for this version of SDK, neither are other necessary header files and lib files. So I modified the Target Platform Version to 8.1. And it worked.

Environment:

• Windows 10
• Visual Studio 2015
• Visual C++

Solution:

1. Open the project's Property Page;
2. Navigate to General page;
3. Modify Target Platform Version to the desired target platform (e.g. 8.1).

Using furl, pip install furl it will be:

 furl.furl('/media/path/').add(path='js/foo.js')

For eslint:

"editor.codeActionsOnSave": { "source.fixAll.eslint": true }

In HTML:

<div ng-repeat="product in products | filter: colorFilter">

In Angular:

$scope.colorFilter = function (item) { 
  if (item.color === 'red' || item.color === 'blue') {
  return item;
 }
};

I will do something like this:

function findLongestWord(str) {
var array = str.split(" ");
var maxLength=array[0].length;
for(var i=0; i < array.length; i++ ) {
if(array[i].length > maxLength) maxLength = array[i].length}
return maxLength;}

findLongestWord("What if we try a super-long word such as otorhinolaryngology");

The code marked as the solution did not work for me. This was my solution.

It Seems fine to me (or raw_input() in Python 2.X). Alternatively, you could use time.sleep() if you want to pause for a certain number of seconds.

import time
print("something")
time.sleep(5.5)    # Pause 5.5 seconds
print("something")

There are many ways to do this, one way is:

sqlite3 auction.db

Followed by:

sqlite> .read create.sql

In general, the SQLite project has really fantastic documentation! I know we often reach for Google before the docs, but in SQLite's case, the docs really are technical writing at its best. It's clean, clear, and concise.

If the accepted answer isn't working right for you then you might try.

str.replace(new RegExp('\n','g'), '<br />')

It worked for me.

I was facing the same problem when I was trying to connect Mysql to a Remote Server. I had found out that I had to change the bind-address to the current private IP address of the DB server. But when I was trying to add the bind-address =0.0.0.0 line in my.cnf file, it was not understanding the line when I tried to create a DB.

Upon searching, I found out the original place where bind-address was declared.

The actual declaration is in : /etc/mysql/mariadb.conf.d/50-server.cnf

Therefore I changed the bind-address directly there and then all seems working.

This problem is just because you have declared the column in CHAR, VARCHAR or TEXT datatype. Just change the datatype to INT, BIGINT etc. This is will solved the problem of your custom ordering.

If @papigee does solution doesn't work, maybe you don't have the permissions.

I tried @papigee solution but does't work without sudo.

I did :

sudo docker exec -it <container id or name> /bin/sh

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

def plotFigure(data_plot,file_name,order):
    fig = plt.figure(order, figsize=(9, 6))
    ax = fig.add_subplot(111)
    bp = ax.boxplot(data_plot)
    fig.savefig(file_name, bbox_inches='tight')
    plt.close()

I prefer the OR form of command, as I find them the most readable (as opposed to having an if after each command). However, the naive way of doing this, command || exit /b %ERRORLEVEL% is wrong.

This is because batch expands variables when a line is first read, rather than when they are being used. This means that if the command in the line above fails, the batch file exits properly, but it exits with return code 0, because that is what the value of %ERRORLEVEL% was at the start of the line. Obviously, this is undesirable in our script, so we have to enable delayed expansion, like so:

SETLOCAL EnableDelayedExpansion

command-1 || exit /b !ERRORLEVEL!
command-2 || exit /b !ERRORLEVEL!
command-3 || exit /b !ERRORLEVEL!
command-4 || exit /b !ERRORLEVEL!

This snippet will execute commands 1-4, and if any of them fails, it will exit with the same exit code as the failing command did.

@Cyntech is right.

Incase your table is empty and you still need to get table column names you can get your column as type Vector,see the following:

ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int columnCount = rsmd.getColumnCount();

Vector<Vector<String>>tableVector = new Vector<Vector<String>>(); 
boolean isTableEmpty = true;
int col = 0;

 while(rs.next())
    {
      isTableEmpty = false;  //set to false since rs.next has data: this means the table is not empty
       if(col != columnCount)
          {
            for(int x = 1;x <= columnCount;x++){
                 Vector<String> tFields = new Vector<String>(); 
                 tFields.add(rsmd.getColumnName(x).toString());
                 tableVector.add(tFields);
             }
            col = columnCount;
          }
     } 


      //if table is empty then get column names only
  if(isTableEmpty){  
      for(int x=1;x<=colCount;x++){
           Vector<String> tFields = new Vector<String>(); 
           tFields.add(rsmd.getColumnName(x).toString());
           tableVector.add(tFields);
        }
      }

 rs.close();
 stmt.close();

 return tableVector; 

I had a similar problem and for my AspNetCore 3.1 application the other answers to this question were not working. I found that configuring a named HttpClient in my Startup.cs and using header propagation of the Cookie header worked perfectly. It also avoids all the concerns about proper disposition of your handler and client. Note if propagation of the request cookies is not what you need (sorry Op) you can set your own cookies when configuring the client factory.

• I used this guide from Microsoft - Make HTTP requests using IHttpClientFactory in ASP.NET Core
• Header propagation is covered in this section - Header propagation middleware

Configure Services with IServiceCollection

services.AddHttpClient("MyNamedClient").AddHeaderPropagation();
services.AddHeaderPropagation(options =>
{
    options.Headers.Add("Cookie");
});

Configure with IApplicationBuilder

builder.UseHeaderPropagation();

• Inject the IHttpClientFactory into your controller or middleware.
• Create your client using var client = clientFactory.CreateClient("MyNamedClient");

To install a specific python package version whether it is the first time, an upgrade or a downgrade use:

pip install --force-reinstall MySQL_python==1.2.4

MySQL_python version 1.2.2 is not available so I used a different version. To view all available package versions from an index exclude the version:

pip install MySQL_python==

Under the connection properties, uncheck "Enable background refresh". This will make the connection refresh when told to, not in the background as other processes happen.

With background refresh disabled, your VBA procedure will wait for your external data to refresh before moving to the next line of code.

Then you just modify the following code:

ActiveWorkbook.Connections("CONNECTION_NAME").Refresh
Sheets("SHEET_NAME").PivotTables("PIVOT_TABLE_NAME").PivotCache.Refresh

You can also turn off background refresh in VBA:

ActiveWorkbook.Connections("CONNECTION_NAME").ODBCConnection.BackgroundQuery = False

For Swift :

self.imageViews.contentMode = UIViewContentMode.ScaleToFill

I checked your XAML, it works fine - e.g. both labels have a gray foreground.
My guess is that you have some style which is affecting the way it looks...

Try moving your XAML to a brand-new window and see for yourself... Then, check if you have any themes or styles (in the Window.Resources for instance) which might be affecting the labels...

I was solving this algorithm and get stuck with the pairs part.

This explanation help me a lot https://betterexplained.com/articles/techniques-for-adding-the-numbers-1-to-100/

So to calculate the sum of series of numbers:

n(n+1)/2

But you need to calculate this

1 + 2 + ... + (n-1)

So in order to get this you can use

n(n+1)/2 - n

that is equal to

n(n-1)/2

Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/

The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.

Setting Up a Custom SSH Server

The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.

You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.

How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.

Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.

To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.

Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.

Example 10-1. sshserver.py

Convert timestamp to date in MYSQL

Make the table with an integer timestamp:

mysql> create table foo(id INT, mytimestamp INT(11));
Query OK, 0 rows affected (0.02 sec)

Insert some values

mysql> insert into foo values(1, 1381262848);
Query OK, 1 row affected (0.01 sec)

Take a look

mysql> select * from foo;
+------+-------------+
| id   | mytimestamp |
+------+-------------+
|    1 |  1381262848 |
+------+-------------+
1 row in set (0.00 sec)

Convert the number to a timestamp:

mysql> select id, from_unixtime(mytimestamp) from foo;
+------+----------------------------+
| id   | from_unixtime(mytimestamp) |
+------+----------------------------+
|    1 | 2013-10-08 16:07:28        |
+------+----------------------------+
1 row in set (0.00 sec)

Convert it into a readable format:

mysql> select id, from_unixtime(mytimestamp, '%Y %D %M %H:%i:%s') from foo;
+------+-------------------------------------------------+
| id   | from_unixtime(mytimestamp, '%Y %D %M %H:%i:%s') |
+------+-------------------------------------------------+
|    1 | 2013 8th October 04:07:28                       |

Here you will find the simplest possible example of using distutils and setup.py:

https://docs.python.org/2/distutils/introduction.html#distutils-simple-example

This assumes that all your code is in a single file and tells how to package a project containing a single module.

I found that, when you use EXTERNAL TABLE and LOCATION together, Hive creates table and initially no data will present (assuming your data location is different from the Hive 'LOCATION').

When you use 'LOAD DATA INPATH' command, the data get MOVED (instead of copy) from data location to location that you specified while creating Hive table.

If location is not given when you create Hive table, it uses internal Hive warehouse location and data will get moved from your source data location to internal Hive data warehouse location (i.e. /user/hive/warehouse/).

PEAR: Mail worked for me sending email messages from Gmail. Also, the instructions: How to Send Email from a PHP Script Using SMTP Authentication (Using PEAR::Mail) helped greatly. Thanks, CMS!

// Let's load the category Model and grab the product collection of that category

$product_collection = Mage::getModel('catalog/category')->load($categoryId)->getProductCollection();

// Now let's loop through the product collection and print the ID of every product 
foreach($product_collection as $product) {
  // Get the product ID

$product_id = $product->getId();

  // Load the full product model based on the product ID

$full_product = Mage::getModel('catalog/product')->load($product_id);

  // Now that we loaded the full product model, let's access all of it's data

  // Let's get the Product Name

  $product_name = $full_product->getName();

  // Let's get the Product URL path

  $product_url = $full_product->getProductUrl();

  // Let's get the Product Image URL

  $product_image_url = $full_product->getImageUrl();

  // Let's print the product information we gathered and continue onto the next one

 echo $product_name;

  echo $product_image_url;


}

I once ran into this situation and I had the dependencies in classpath. The solution was to include javax.mail and javax.activation libraries in the container's (eg. tomcat) lib folder. Using maven -set them to provided scope and it should work. You will have shared email libs in classpath for all projects.

This would be concise way in Kotlin.

    fun AssetManager.copyRecursively(assetPath: String, targetFile: File) {
        val list = list(assetPath)
        if (list.isEmpty()) { // assetPath is file
            open(assetPath).use { input ->
                FileOutputStream(targetFile.absolutePath).use { output ->
                    input.copyTo(output)
                    output.flush()
                }
            }

        } else { // assetPath is folder
            targetFile.delete()
            targetFile.mkdir()

            list.forEach {
                copyRecursively("$assetPath/$it", File(targetFile, it))
            }
        }
    }

Another interesting project is texlive.js.

It allows you to compile (La)TeX to PDF in the browser.

In SQL Server Import and Export Wizard you can adjust the source data types in the Advanced tab (these become the data types of the output if creating a new table, but otherwise are just used for handling the source data).

The data types are annoyingly different than those in MS SQL, instead of VARCHAR(255) it's DT_STR and the output column width can be set to 255. For VARCHAR(MAX) it's DT_TEXT.

So, on the Data Source selection, in the Advanced tab, change the data type of any offending columns from DT_STR to DT_TEXT (You can select multiple columns and change them all at once).

You have to manage client session on the client side. This means that you have to send authentication data with every request, and you probably, but not necessary have an in-memory cache on the server, which pairs auth data to user information like identity, permissions, etc...

This REST statelessness constraint is very important. Without applying this constraint, your server side application won't scale well, because maintaining every single client session will be its Achilles' heel.

Try this:

sudo apt-get install -y curl

If the verification logic is non-trivial, it will be messy to write a large lambda method (as your example shows). You could put all the test statements in a separate method, but I don't like to do this because it disrupts the flow of reading the test code.

Another option is to use a callback on the Setup call to store the value that was passed into the mocked method, and then write standard Assert methods to validate it. For example:

// Arrange
MyObject saveObject;
mock.Setup(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()))
        .Callback<int, MyObject>((i, obj) => saveObject = obj)
        .Returns("xyzzy");

// Act
// ...

// Assert
// Verify Method was called once only
mock.Verify(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()), Times.Once());
// Assert about saveObject
Assert.That(saveObject.TheProperty, Is.EqualTo(2));

You can simply get HQ youtube thumbnails..

If you write

a = [1, 2, 3, 4, 5]
print(*a, sep = ',')

You get this output: 1,2,3,4,5

To expand on some of the previous answers, I found that Oracle DATE objects behave different from Oracle TIMESTAMP objects. In particular, if you set your NLS_DATE_FORMAT to include fractional seconds, the entire time portion is omitted.

• Format "YYYY-MM-DD HH24:MI:SS" works as expected, for DATE and TIMESTAMP
• Format "YYYY-MM-DD HH24:MI:SSXFF" displays just the date portion for DATE, works as expected for TIMESTAMP

My personal preference is to set DATE to "YYYY-MM-DD HH24:MI:SS", and to set TIMESTAMP to "YYYY-MM-DD HH24:MI:SSXFF".

Actually the difference between hibernate save() and persist() methods is depends on generator class we are using.

If our generator class is assigned, then there is no difference between save() and persist() methods. Because generator ‘assigned’ means, as a programmer we need to give the primary key value to save in the database right [ Hope you know this generators concept ] In case of other than assigned generator class, suppose if our generator class name is Increment means hibernate it self will assign the primary key id value into the database right [ other than assigned generator, hibernate only used to take care the primary key id value remember ], so in this case if we call save() or persist() method then it will insert the record into the database normally But hear thing is, save() method can return that primary key id value which is generated by hibernate and we can see it by

long s = session.save(k);

In this same case, persist() will never give any value back to the client.

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;-).

The model (@Model) only exists while the page is being constructed. Once the page is rendered in the browser, all that exists is HTML, JavaScript and CSS.

What you will want to do is put the PostID in a hidden field. As the PostID value is fixed, there actually is no need for JavaScript. A simple @HtmlHiddenFor will suffice.

However, you will want to change your foreach loop to a for loop. The final solution will look something like this:

for (int i = 0 ; i < Model.Post; i++)
{
    <br/>
    <b>Posted by :</b> @Model.Post[i].Username <br/>
    <span>@Model.Post[i].Content</span> <br/>
    if(Model.loginuser == Model.username)
    {
        @Html.HiddenFor(model => model.Post[i].PostID)
        @Html.TextAreaFor(model => model.addcomment.Content)
        <button type="submit">Add Comment</button>
    }
}

Windows Server 2003 and later (i.e. anything after Windows XP 32 bit) provide the where.exe program which does some of what which does, though it matches all types of files, not just executable commands. (It does not match built-in shell commands like cd.) It will even accept wildcards, so where nt* finds all files in your %PATH% and current directory whose names start with nt.

Try where /? for help.

Note that Windows PowerShell defines where as an alias for the Where-Object cmdlet, so if you want where.exe, you need to type the full name instead of omitting the .exe extension.

form_for @user, :url => url_for(:controller => 'mycontroller', :action => 'myaction')

or

form_for @user, :url => whatever_path

The value you are setting in the timeout attribute is the one of the correct ways to set the session timeout value.

The timeout attribute specifies the number of minutes a session can be idle before it is abandoned. The default value for this attribute is 20.

By assigning a value of 1 to this attribute, you've set the session to be abandoned in 1 minute after its idle.

To test this, create a simple aspx page, and write this code in the Page_Load event,

Response.Write(Session.SessionID);

Open a browser and go to this page. A session id will be printed. Wait for a minute to pass, then hit refresh. The session id will change.

Now, if my guess is correct, you want to make your users log out as soon as the session times out. For doing this, you can rig up a login page which will verify the user credentials, and create a session variable like this -

Session["UserId"] = 1;

Now, you will have to perform a check on every page for this variable like this -

if(Session["UserId"] == null)
    Response.Redirect("login.aspx");

This is a bare-bones example of how this will work.

But, for making your production quality secure apps, use Roles & Membership classes provided by ASP.NET. They provide Forms-based authentication which is much more reliabletha the normal Session-based authentication you are trying to use.

try

if ($('#column-left form:visible').length > 0) { ...

You can get the milliseconds since 1/1/1970 using such code:

private static DateTime JanFirst1970 = new DateTime(1970, 1, 1);
public static long getTime()
{
    return (long)((DateTime.Now.ToUniversalTime() - JanFirst1970).TotalMilliseconds + 0.5);
}

A solution using the curses module. Printing a numeric value corresponding to each key pressed:

import curses

def main(stdscr):
    # do not wait for input when calling getch
    stdscr.nodelay(1)
    while True:
        # get keyboard input, returns -1 if none available
        c = stdscr.getch()
        if c != -1:
            # print numeric value
            stdscr.addstr(str(c) + ' ')
            stdscr.refresh()
            # return curser to start position
            stdscr.move(0, 0)

if __name__ == '__main__':
    curses.wrapper(main)

Adding this late answer to show a case most people will come across. If you only need to see what is the last item in the list, use the last key word:

<div *ngFor="let item of devcaseFeedback.reviewItems; let last = last">
  <divider *ngIf="!last"></divider>
</div>

This will add the divider component to every item except the last.

Because of the comment below, I will add the rest of the ngFor exported values that can be aliased to local variables (As are shown in the docs):

• $implicit: T: The value of the individual items in the iterable (ngForOf).
• ngForOf: NgIterable: The value of the iterable expression. Useful when the expression is more complex then a property access, for example when using the async pipe (userStreams | async).
• index: number: The index of the current item in the iterable.
• count: number: The length of the iterable.
• count: number: The length of the iterable.
• first: boolean: True when the item is the first item in the iterable.
• last: boolean: True when the item is the last item in the iterable.
• even: boolean: True when the item has an even index in the iterable.
• odd: boolean: True when the item has an odd index in the iterable.

Here is how you can handle this:

    var scrollStop = function (callback) {_x000D_
        if (!callback || typeof callback !== 'function') return;_x000D_
        var isScrolling;_x000D_
        window.addEventListener('scroll', function (event) {_x000D_
            window.clearTimeout(isScrolling);_x000D_
            isScrolling = setTimeout(function() {_x000D_
                callback();_x000D_
            }, 66);_x000D_
        }, false);_x000D_
    };_x000D_
    scrollStop(function () {_x000D_
        console.log('Scrolling has stopped.');_x000D_
    });
