Another way to do this in PHP 5.6+ would be to use the ... token

$a = array('a', 'b');
$b = array('c', 'd');

array_push($a, ...$b);

// $a is now equals to array('a','b','c','d');

This will also work with any Traversable

$a = array('a', 'b');
$b = new ArrayIterator(array('c', 'd'));

array_push($a, ...$b);

// $a is now equals to array('a','b','c','d');

A warning though:

• in PHP versions before 7.3 this will cause a fatal error if $b is an empty array or not traversable e.g. not an array
• in PHP 7.3 a warning will be raised if $b is not traversable

It's usually the metacharacter . when not inside a character class.

So use ^.{1,35}$. However, dot does not include newlines unless the dot-all modifier is applied against it.

You can use ^[\S\s]{1,35}$ without any modifiers, and this includes newlines as well.

To get it to work with FullScreen:

Use the ionic keyboard plugin. This allows you to listen for when the keyboard appears and disappears.

OnDeviceReady add these event listeners:

// Allow Screen to Move Up when Keyboard is Present
window.addEventListener('native.keyboardshow', onKeyboardShow);
// Reset Screen after Keyboard hides
window.addEventListener('native.keyboardhide', onKeyboardHide);

The Logic:

function onKeyboardShow(e) {
    // Get Focused Element
    var thisElement = $(':focus');
    // Get input size
    var i = thisElement.height();
    // Get Window Height
    var h = $(window).height()
    // Get Keyboard Height
    var kH = e.keyboardHeight
    // Get Focused Element Top Offset
    var eH = thisElement.offset().top;
    // Top of Input should still be visible (30 = Fixed Header)
    var vS = h - kH;
    i = i > vS ? (vS - 30) : i;
    // Get Difference
    var diff = (vS - eH - i);
    if (diff < 0) {
        var parent = $('.myOuter-xs.myOuter-md');
        // Add Padding
        var marginTop = parseInt(parent.css('marginTop')) + diff - 25;
        parent.css('marginTop', marginTop + 'px');
    }
}

function onKeyboardHide(e) {
  // Remove All Style Attributes from Parent Div
  $('.myOuter-xs.myOuter-md').removeAttr('style');
}

Basically if they difference is minus then that is the amount of pixels that the keyboard is covering of your input. So if you adjust your parent div by this that should counteract it.

Adding timeouts to the logic say 300ms should also optimise performance (as this will allow keyboard time to appear.

Use scrollTop() to get or set the scroll position.

Note: This applies to pre-4 VirtualBox. In VB4, HDD expansion has been introduced.

According to the VirtualBox documentation:

When creating an image, its size needs to be specified, which determines this fixed geometry. It is therefore not possible to change the size of the virtual hard disk later.

So, the easiest way to add additional space to an existing VM is to attach a second hard disk. Go to the VM Settings > Hard Disks > Add New. Then, click the "Select Hard Drive" button and click on "New". Follow the wizard to create a new virtual hard disk. It will then show up as D: or E: in your guest OS.

The oracle limit is 1000 parameters. The issue has been resolved by hibernate in version 4.1.7 although by splitting the passed parameter list in sets of 500 see JIRA HHH-1123

Take a peek at the ng-click directive source:

...
compile: function($element, attr) {
  var fn = $parse(attr[directiveName]);
  return function(scope, element, attr) {
    element.on(lowercase(name), function(event) {
      scope.$apply(function() {
        fn(scope, {$event:event});
      });
    });
  };
}

It shows how the event object is being passed on to the ng-click expression, using $event as a name of the parameter. This is done by the $parse service, which doesn't allow for the parameters to bleed into the target scope, which means the answer is no, you can't access the $event object any other way but through the callback parameter.

To pass/use the variables, first create parameters in the configure section of Jenkins. Parameters that you use can be of type text, String, file, etc.

After creating them, use the variable reference in the fields you want to.

For example: I have configured/created two variables for Email-subject and Email-recipentList, and I have used their reference in the EMail-ext plugin (attached screenshot).

I would imagine that this would be covered by CSS Tables, a specification which, while mentioned on the CSS homepage, appears to currently be at a state of "not yet published in any form"

In practical terms, you can't achieve this at present.

I installed npm after Visual studio code, closed all visual studio instances and opened again and it started working.

Try below for your query. where val is your string or column name.

CASE WHEN PATINDEX('%[a-z]%', REVERSE(val)) > 1
                THEN LEFT(val, LEN(val) - PATINDEX('%[a-z]%', REVERSE(val)) + 1)
            ELSE '' END

The question itself has already been addressed above. Just adding part of the default values.

As per http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionX.html

The default value of Xmx will depend on platform and amount of memory available in the system.

To do this you can use following git command.

 git rebase -i HEAD~n

n(=4 here) is the number of last commit. Then you got following options,

pick 01d1124 Message....
pick 6340aaa Message....
pick ebfd367 Message....
pick 30e0ccb Message....

Update like below pick one commit and squash the others into the most recent,

p 01d1124 Message....
s 6340aaa Message....
s ebfd367 Message....
s 30e0ccb Message....

Here's an implementation of the highest-voted answer that returns -1 when the item is not found:

public static int FindIndex<T>(this IEnumerable<T> items, Func<T, bool> predicate)
{
    var itemsWithIndices = items.Select((item, index) => new { Item = item, Index = index });
    var matchingIndices =
        from itemWithIndex in itemsWithIndices
        where predicate(itemWithIndex.Item)
        select (int?)itemWithIndex.Index;

    return matchingIndices.FirstOrDefault() ?? -1;
}

I found the easiest solution on Windows is to build from source.

You can pretty much follow this guide: http://spark.apache.org/docs/latest/building-spark.html

Download and install Maven, and set MAVEN_OPTS to the value specified in the guide.

But if you're just playing around with Spark, and don't actually need it to run on Windows for any other reason that your own machine is running Windows, I'd strongly suggest you install Spark on a linux virtual machine. The simplest way to get started probably is to download the ready-made images made by Cloudera or Hortonworks, and either use the bundled version of Spark, or install your own from source or the compiled binaries you can get from the spark website.

Here's an example using http://www.geoplugin.net/json.gp

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip={$ip}"));
echo $details;

Give them a trivial pom with these jars listed as dependencies and instructions to run:

mvn dependency:go-offline

This will pull the dependencies to the local repo.

A more direct solution is dependency:get, but it's a lot of arguments to type:

mvn dependency:get -DrepoUrl=something -Dartifact=group:artifact:version

It turns it into a bytes literal (or str in 2.x), and is valid for 2.6+.

The r prefix causes backslashes to be "uninterpreted" (not ignored, and the difference does matter).

$data = $this->db->get_where('columnname',array('code' => 'B'));
$this->db->where_in('columnname',$data);
$this->db->where('code !=','B');
$query =  $this->db->get();
return $query->result_array();

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

I usually read command output in to variables using the FOR command as it saves having to create temporary files. For example:

FOR /F "usebackq" %i IN (`hostname`) DO SET MYVAR=%i

Note, the above statement will work on the command line but not in a batch file. To use it in batch file escape the % in the FOR statement by putting them twice:

FOR /F "usebackq" %%i IN (`hostname`) DO SET MYVAR=%%i
ECHO %MYVAR%

There's a lot more you can do with FOR. For more details just type HELP FOR at command prompt.

For special permissions, such as android.Manifest.permission.PACKAGE_USAGE_STATS used AppOpsManager:
Kotlin

private fun hasPermission(permission:String, permissionAppOpsManager:String): Boolean {
    var granted = false
    if (VERSION.SDK_INT >= VERSION_CODES.M) {
        // requires kitkat
        val appOps = applicationContext!!.getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager

        // requires lollipop
        val mode = appOps.checkOpNoThrow(permissionAppOpsManager,
                              android.os.Process.myUid(), applicationContext!!.packageName)

        if (mode == AppOpsManager.MODE_DEFAULT) {
            granted = applicationContext!!.checkCallingOrSelfPermission(permission) == PackageManager.PERMISSION_GRANTED
        } else {
            granted = mode == AppOpsManager.MODE_ALLOWED
        }
    }

    return granted
}

and anywhere in code:

val permissionAppOpsManager = AppOpsManager.OPSTR_GET_USAGE_STATS
val permission = android.Manifest.permission.PACKAGE_USAGE_STATS
val permissionActivity = Settings.ACTION_USAGE_ACCESS_SETTINGS

if (hasPermission(permission, permissionAppOpsManager)) {
    Timber.i("has permission: $permission")
    // do here what needs permission
} else {
    Timber.e("has no permission: $permission")
    // start activity to get permission
    startActivity(Intent(permissionActivity))
}

Other permissions you can get with TedPermission library

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

dict.copy() is a shallow copy function for dictionary
id is built-in function that gives you the address of variable

First you need to understand "why is this particular problem is happening?"

In [1]: my_dict = {'a': [1, 2, 3], 'b': [4, 5, 6]}

In [2]: my_copy = my_dict.copy()

In [3]: id(my_dict)
Out[3]: 140190444167808

In [4]: id(my_copy)
Out[4]: 140190444170328

In [5]: id(my_copy['a'])
Out[5]: 140190444024104

In [6]: id(my_dict['a'])
Out[6]: 140190444024104

The address of the list present in both the dicts for key 'a' is pointing to same location.
Therefore when you change value of the list in my_dict, the list in my_copy changes as well.

Solution for data structure mentioned in the question:

In [7]: my_copy = {key: value[:] for key, value in my_dict.items()}

In [8]: id(my_copy['a'])
Out[8]: 140190444024176

Or you can use deepcopy as mentioned above.

Simple:

byte[] data = Convert.FromBase64String(encodedString);
string decodedString = Encoding.UTF8.GetString(data);

The bootstrap docs says about this:

Requires custom widths Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.

The default width of 100% as all form elements gets when they got the class form-control didn't apply if you use the form-inline class on your form.

You could take a look at the bootstrap.css (or .less, whatever you prefer) where you will find this part:

.form-inline {

  // Kick in the inline
  @media (min-width: @screen-sm-min) {
    // Inline-block all the things for "inline"
    .form-group {
      display: inline-block;
      margin-bottom: 0;
      vertical-align: middle;
    }

    // In navbar-form, allow folks to *not* use `.form-group`
    .form-control {
      display: inline-block;
      width: auto; // Prevent labels from stacking above inputs in `.form-group`
      vertical-align: middle;
    }
    // Input groups need that 100% width though
    .input-group > .form-control {
      width: 100%;
    }

    [...]
  }
}

Maybe you should take a look at input-groups, since I guess they have exactly the markup you want to use (working fiddle here):

<div class="row">
   <div class="col-lg-12">
    <div class="input-group input-group-lg">
      <input type="text" class="form-control input-lg" id="search-church" placeholder="Your location (City, State, ZIP)">
      <span class="input-group-btn">
        <button class="btn btn-default btn-lg" type="submit">Search</button>
      </span>
    </div>
  </div>
</div>

My suggestion to you is to write your own utility service. You can include the service in each controller or create a parent controller, assign the utility service to your scope and then every child controller will inherit this without you having to include it.

Example: http://plnkr.co/edit/NI7V9cLkQmEtWO36CPXy?p=preview

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, Utils) {
    $scope.utils = Utils;
});

app.controller('ChildCtrl', function($scope, Utils) {
   $scope.undefined1 = Utils.isUndefinedOrNull(1);  // standard DI
   $scope.undefined2 = $scope.utils.isUndefinedOrNull(1);  // MainCtrl is parent

});

app.factory('Utils', function() {
  var service = {
     isUndefinedOrNull: function(obj) {
         return !angular.isDefined(obj) || obj===null;
     }

  }

  return service;
});

Or you could add it to the rootScope as well. Just a few options for extending angular with your own utility functions.

A service creation example of using backslashes with many double quotes.

C:\Windows\system32>sc.exe create teagent binpath= "\"C:\Program Files\Tripwire\TE\Agent\bin\wrapper.exe\" -s \"C:\Program Files\Tripwire\TE\Agent\bin\agent.conf\"" DisplayName= "Tripwire Enterprise Agent"

[SC] CreateService SUCCESS

Try redirecting the output like this:

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose >$null 2>&1

You can pass this when you call the function

<button onclick="doSomething('param',this)" id="id_button">action</button>

<script>
    function doSomething(param,me){

    var source = me
    console.log(source);
}
</script>

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

  <input type="radio" name="radiobutton" value="B" onclick = "populateData(event)">

    <div id="content"></div>

-----------------JS- code------------

var targetDiv = document.getElementById('content');
    var htmlContent = '';

    function populateData(event){
      switch(event.target.value){
        case 'A':{
         htmlContent = 'Content for A';
          break;
        }
        case 'B':{
          htmlContent = "content for B";
break;
        }
      }
      targetDiv.innerHTML = htmlContent;
    }

Step1: on click of the radio button it calls function populate data, with event (an object that has event details such as name of the element, value etc..);

Step2: I extracted the value through event.target.value and then simple switch will give me freedom to add custom text.

Create a "jump link" using the following format:

http://www.somesite.com/somepage#anchor

Where anchor is the id of the element you wish to link to on that page. Use browser development tools / view source to find the id of the element you wish to link to.

If the element doesnt have an id and you dont control that site then you cant do it.

For your purposes, I recommend using SVG, since you get DOM events, like mouse handling, including drag and drop, included, you don't have to implement your own redraw, and you don't have to keep track of the state of your objects. Use Canvas when you have to do bitmap image manipulation and use a regular div when you want to manipulate stuff created in HTML. As to performance, you'll find that modern browsers are now accelerating all three, but that canvas has received the most attention so far. On the other hand, how well you write your javascript is critical to getting the most performance with canvas, so I'd still recommend using SVG.

Try using string.Contains () combined with EndsWith.

var results = from c in db.Customers
              where c.FullName.Contains (FirstName) && c.FullName.EndsWith (LastName)
              select c;

$('iframe').load(function(){
      $(".loading").remove();
    alert("iframe is done loading")
}).show();


<iframe src="http://www.google.com" style="display:none;" width="600" height="300"/>
<div class="loading" style="width:600px;height:300px;">iframe loading</div>

I think, this could be done without IIS URL Rewrite module. <httpRedirect> supports wildcards, so you can configure it this way:

  <system.webServer>
    <httpRedirect enabled="true">
      <add wildcard="/" destination="/menu_1/MainScreen.aspx" />
    </httpRedirect>
  </system.webServer>

Note that you need to have the "HTTP Redirection" feature enabled on IIS - see HTTP Redirects

Example: Suppose you have set some text in textview and you want to provide a link on a particular text expression: "Click on #facebook will take you to facebook.com"

In layout xml:

<TextView
            android:id="@+id/testtext"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

In Activity:

String text  =  "Click on #facebook will take you to facebook.com";
tv.setText(text);
Pattern tagMatcher = Pattern.compile("[#]+[A-Za-z0-9-_]+\\b");
String newActivityURL = "content://ankit.testactivity/";
Linkify.addLinks(tv, tagMatcher, newActivityURL);

Also create one tag provider as:

public class TagProvider extends ContentProvider {

    @Override
    public int delete(Uri arg0, String arg1, String[] arg2) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public String getType(Uri arg0) {
        return "vnd.android.cursor.item/vnd.cc.tag";
    }

    @Override
    public Uri insert(Uri arg0, ContentValues arg1) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public boolean onCreate() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public Cursor query(Uri arg0, String[] arg1, String arg2, String[] arg3,
                        String arg4) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public int update(Uri arg0, ContentValues arg1, String arg2, String[] arg3) {
        // TODO Auto-generated method stub
        return 0;
    }

}

In manifest file make as entry for provider and test activity as:

<provider
    android:name="ankit.TagProvider"
    android:authorities="ankit.testactivity" />

<activity android:name=".TestActivity"
    android:label = "@string/app_name">
    <intent-filter >
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="vnd.android.cursor.item/vnd.cc.tag" />
    </intent-filter>
</activity>

Now when you click on #facebook, it will invoke testactivtiy. And in test activity you can get the data as:

Uri uri = getIntent().getData();

Swift 5 answer based on @ZpaceZombor's excellent answer

If you have a UIImage, just use

var image: UIImage = .... 
image.draw(in: CGRect)

If you have a CGImage use my category below

Note: Unlike some other answers, this one takes into account that the rect you want to draw in might have y != 0. Those answers that don't take that into account are incorrect and won't work in the general case.

extension CGContext {
    final func drawImage(image: CGImage, inRect rect: CGRect) {

        //flip coords
        let ty: CGFloat = (rect.origin.y + rect.size.height)
        translateBy(x: 0, y: ty)
        scaleBy(x: 1.0, y: -1.0)

        //draw image
        let rect__y_zero = CGRect(x: rect.origin.x, y: 0, width: rect.width, height: rect.height)
        draw(image, in: rect__y_zero)

        //flip back
        scaleBy(x: 1.0, y: -1.0)
        translateBy(x: 0, y: -ty)

    }
} 

Use like this:

let imageFrame: CGRect = ...
let context: CGContext = ....
let img: CGImage = ..... 
context.drawImage(image: img, inRect: imageFrame)

I always include the js files in the head of the html document and them in the action just call the javascript function. Something like this:

action="javascript:checkout()"

You try this?

Don't forget include the script reference in the html head.

I don't know cause of that works in firefox. Regards.

Warning! chrome.tabs.getSelected is deprecated. Please use chrome.tabs.query as shown in the other answers.

First, you've to set the permissions for the API in manifest.json:

"permissions": [
    "tabs"
]

And to store the URL :

chrome.tabs.getSelected(null,function(tab) {
    var tablink = tab.url;
});

This code is for the headset profiles, probably it will work for other profiles too. First you need to provide profile listener (Kotlin code):

private val mProfileListener = object : BluetoothProfile.ServiceListener {
    override fun onServiceConnected(profile: Int, proxy: BluetoothProfile) {
        if (profile == BluetoothProfile.HEADSET) 
            mBluetoothHeadset = proxy as BluetoothHeadset            
    }

    override fun onServiceDisconnected(profile: Int) {
        if (profile == BluetoothProfile.HEADSET) {
            mBluetoothHeadset = null
        }
    }
}

Then while checking bluetooth:

mBluetoothAdapter.getProfileProxy(context, mProfileListener, BluetoothProfile.HEADSET)
if (!mBluetoothAdapter.isEnabled) {
    return Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)
}

It takes a bit of time until onSeviceConnected is called. After that you may get the list of the connected headset devices from:

mBluetoothHeadset!!.connectedDevices

After reading this tutorial, I tried to implement it to my program.

I have 4-5 files that contain addresses. Each file has approx 30 million records. I am using the same configuration that you are suggesting but my number of INSERTs per second is way low (~10.000 records per sec).

Here is where your suggestion fails. You use a single transaction for all the records and a single insert with no errors/fails. Let's say that you are splitting each record into multiple inserts on different tables. What happens if the record is broken?

The ON CONFLICT command does not apply, cause if you have 10 elements in a record and you need each element inserted to a different table, if element 5 gets a CONSTRAINT error, then all previous 4 inserts need to go too.

So here is where the rollback comes. The only issue with the rollback is that you lose all your inserts and start from the top. How can you solve this?

My solution was to use multiple transactions. I begin and end a transaction every 10.000 records (Don't ask why that number, it was the fastest one I tested). I created an array sized 10.000 and insert the successful records there. When the error occurs, I do a rollback, begin a transaction, insert the records from my array, commit and then begin a new transaction after the broken record.

This solution helped me bypass the issues I have when dealing with files containing bad/duplicate records (I had almost 4% bad records).

The algorithm I created helped me reduce my process by 2 hours. Final loading process of file 1hr 30m which is still slow but not compared to the 4hrs that it initially took. I managed to speed the inserts from 10.000/s to ~14.000/s

If anyone has any other ideas on how to speed it up, I am open to suggestions.

UPDATE:

In Addition to my answer above, you should keep in mind that inserts per second depending on the hard drive you are using too. I tested it on 3 different PCs with different hard drives and got massive differences in times. PC1 (1hr 30m), PC2 (6hrs) PC3 (14hrs), so I started wondering why would that be.

After two weeks of research and checking multiple resources: Hard Drive, Ram, Cache, I found out that some settings on your hard drive can affect the I/O rate. By clicking properties on your desired output drive you can see two options in the general tab. Opt1: Compress this drive, Opt2: Allow files of this drive to have contents indexed.

By disabling these two options all 3 PCs now take approximately the same time to finish (1hr and 20 to 40min). If you encounter slow inserts check whether your hard drive is configured with these options. It will save you lots of time and headaches trying to find the solution

In the AWS console, if you navigate to S3, you will see your folders listed. If you navigate to the folder, you will see the object (s) listed. right click and you can rename. OR, you can check the box in front of your object, then from the pull down menu named ACTIONS, you can select rename. Just worked for me, 3-31-2019

Where clause and args work together to form the WHERE statement of the SQL query. So say you looking to express

WHERE Column1 = 'value1' AND Column2 = 'value2'

Then your whereClause and whereArgs will be as follows

String whereClause = "Column1 =? AND Column2 =?";
String[] whereArgs = new String[]{"value1", "value2"};

If you want to select all table columns, i believe a null string passed to tableColumns will suffice.

It means you compiled with e.g. gcc -O3 and the gcc optimiser found that some of your variables were redundant in some way that allowed them to be optimised away. In this particular case you appear to have three variables a, b, c with the same value and presumably they can all be aliassed to a single variable. Compile with optimisation disabled, e.g. gcc -O0, if you want to see such variables (this is generally a good idea for debug builds in any case).

For performance, it usually best to make the code as simple and clear as possible and this will often perform well (as the JIT will optimise this code best). In your case, the simplest examples are also likely to be the fastest.

I would do either

int cmp = a > b ? +1 : a < b ? -1 : 0;

or a longer version

int cmp;
if (a > b)
   cmp = +1;
else if (a < b)
   cmp = -1;
else
   cmp = 0;

or

int cmp = Integer.compare(a, b); // in Java 7
int cmp = Double.compare(a, b); // before Java 7

It's best not to create an object if you don't need to.

Performance wise, the first is best.

If you know for sure that you won't get an overflow you can use

int cmp = a - b; // if you know there wont be an overflow.

you won't get faster than this.

I was having the issue previously in XAMPP localhost with phpmyadmin version 4.2.11.

Increasing the timeout in php.ini didn't helped either.

Then I edited xampp\phpMyAdmin\libraries\config.default.php to change the value of $cfg['ExecTimeLimit'], which was 300 by default.

That solved my issue.

To extend ko-dos' answer, here's an alias to list all container names and their IP addresses:

Here's a one-liner slim way for layering text on top of an input in jQuery using ES6 syntax.

$('.input-group > input').focus(e => $(e.currentTarget).parent().find('.placeholder').hide()).blur(e => { if (!$(e.currentTarget).val()) $(e.currentTarget).parent().find('.placeholder').show(); });

}

.input-group > .placeholder {

  transform: translateY(-50%);
  color: #929292;
}

There is a C# Google Voice API... there is limited documentation, however the download has an application that 'works' using the API that is included:

In order of preference:

1. If you are using a templating engine (e.g. Twig, Smarty, Blade), check that it offers context-sensitive escaping. I know from experience that Twig does. {{ var|e('html_attr') }}
2. If you want to allow HTML, use HTML Purifier. Even if you think you only accept Markdown or ReStructuredText, you still want to purify the HTML these markup languages output.
3. Otherwise, use htmlentities($var, ENT_QUOTES | ENT_HTML5, $charset) and make sure the rest of your document uses the same character set as $charset. In most cases, 'UTF-8' is the desired character set.

Also, make sure you escape on output, not on input.

In plain vanilla JavaScript, with no libraries? It's an error. $ is simply an identifier, and is undefined unless you define it.

jQuery defines $ as it's own "everything object" (also known as jQuery so you can use it without conflicting with other libraries). If you're not using jQuery (or some other library that defines it), then $ will not be defined.

Or are you asking what the equivalent is in plain JavaScript? In that case, you probably want window.onload, which isn't exactly equivalent, but is the quickest and easiest way to get close to the same effect in vanilla JavaScript.

First you have to change values in php.ini file as per your requirements.

post_max_size = 1024M 
upload_max_filesize = 1024M 
max_execution_time = 3600
max_input_time = 3600 
memory_limit = 1024M 

Note - Change these values carefully. These values will impact for all of your projects of that server.

Now, If above solutions are not working, kindly check your phpmyadmin.conf file. If you are using WAMP so you can find the file in "C:\wamp64\alias".

You have to change below values.

Values already in file are -

  php_admin_value upload_max_filesize 128M
  php_admin_value post_max_size 128M
  php_admin_value max_execution_time 360
  php_admin_value max_input_time 360

Change above code to -

#  php_admin_value upload_max_filesize 128M
#  php_admin_value post_max_size 128M
#  php_admin_value max_execution_time 360
#  php_admin_value max_input_time 360

Now just restart your server, to work with changed values. :)

Another possible cause of similar issue could be wrong processorArchitecture in the cx_freeze manifest, trying to load x86 common controls dll in x64 process - should be fixed by this patch:

According to the angularjs event docs the receiving end should be containing arguments with a structure like

@params

-- {Object} event being the event object containing info on the event

-- {Object} args that are passed by the callee (Note that this can only be one so better to send in a dictionary object always)

$scope.$on('fooEvent', function (event, args) { console.log(args) }); From your code

Also if you are trying to get a shared piece of information to be available accross different controllers there is an another way to achieve that and that is angular services.Since the services are singletons information can be stored and fetched across controllers.Simply create getter and setter functions in that service, expose these functions, make global variables in the service and use them to store the info

echo "text to echo" > file.txt

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

While many people will suggest more or less strict Hungarian notation variants (scary!), for naming suggestions I'd suggest you take a look at Google C++ Coding Guidelines. This may well be not the most popular naming conventions, but at least it's fairly complete. Apart from sound naming conventions, there's some useful guidelines there, however much of it should be taken with a grain of salt (exception ban for example, and the tendency to keep away from modern C++ coding style).

Although personally I like the extreme low-tech convention style of STL and Boost ;).

You can use -match instead -eq if you also want to exclude files that only contain whitespace characters:

@(gc c:\FileWithEmptyLines.txt) -match '\S'  | out-file c:\FileWithNoEmptyLines

The answer below is related to this deprecation warning occurring in the Fragments tutorial on the Android developer website and may not be related to the posts above.

I used this code on the tutorial lesson and it did worked.

public void onAttach(Context context){
    super.onAttach(context);

    Activity activity = getActivity();

I was worried that activity maybe null as what the documentation states.

getActivity

FragmentActivity getActivity () Return the FragmentActivity this fragment is currently associated with. May return null if the fragment is associated with a Context instead.

But the onCreate on the main_activity clearly shows that the fragment was loaded and so after this method, calling get activity from the fragment will return the main_activity class.

getSupportFragmentManager().beginTransaction() .add(R.id.fragment_container, firstFragment).commit();

I hope I am correct with this. I am an absolute newbie.

The simple solution using geom_abline:

geom_abline(slope = coef(data.lm)[[2]], intercept = coef(data.lm)[[1]])

Where data.lm is an lm object, and coef(data.lm) looks something like this:

> coef(data.lm)
(Intercept)    DepDelay 
  -2.006045    1.025109 

The numeric indexing assumes that (Intercept) is listed first, which is the case if the model includes an intercept. If you have some other linear model object, just plug in the slope and intercept values similarly.

Open the console and then enter:

• keys(window) to see variables
• dir(window) to see objects

SELECT x.name, x.summary, (x.summary / COUNT(*)) as percents_of_total
FROM tbl t
INNER JOIN 
(SELECT name, SUM(value) as summary
FROM tbl
WHERE year BETWEEN 2000 AND 2001
GROUP BY name) x ON x.name = t.name
GROUP BY x.name, x.summary

You can go to Design mode and select "Fix" at the bottom of the warning. Then a pop up will appear (seems like it's going to register the new string) and voila, the error is fixed.

You could try using the system stored procedure sp_help_job. This returns information on the job, its steps, schedules and servers. For example

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

SQL Books Online should contain lots of information about the records it returns.

For returning information on multiple jobs, you could try querying the following system tables which hold the various bits of information on the job

• msdb.dbo.SysJobs
• msdb.dbo.SysJobSteps
• msdb.dbo.SysJobSchedules
• msdb.dbo.SysJobServers
• msdb.dbo.SysJobHistory

Their names are fairly self-explanatory (apart from SysJobServers which hold information on when the job last run and the outcome).

Again, information on the fields can be found at MSDN. For example, check out the page for SysJobs

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

You can also accomplish this by breaking things up into separate logical statements by including & to separate the statements.

subset(my.df, my.df$v1 != "b" & my.df$v1 != "d" & my.df$v1 != "e")

This is not elegant and takes more code but might be more readable to newer R users. As pointed out in a comment above, subset is a "convenience" function that is best used when working interactively.

Connect to the server as "system" using SID. Execute this query:

select value from v$parameter where name like '%service_name%';

It worked for me.

BYTE

I am trying to answer this question from C++ perspective.

The C++ standard defines ‘byte’ as “Addressable unit of data large enough to hold any member of the basic character set of the execution environment.”

What this means is that the byte consists of at least enough adjacent bits to accommodate the basic character set for the implementation. That is, the number of possible values must equal or exceed the number of distinct characters. In the United States, the basic character sets are usually the ASCII and EBCDIC sets, each of which can be accommodated by 8 bits. Hence it is guaranteed that a byte will have at least 8 bits.

In other words, a byte is the amount of memory required to store a single character.

If you want to verify ‘number of bits’ in your C++ implementation, check the file ‘limits.h’. It should have an entry like below.

#define CHAR_BIT      8         /* number of bits in a char */

WORD

A Word is defined as specific number of bits which can be processed together (i.e. in one attempt) by the machine/system. Alternatively, we can say that Word defines the amount of data that can be transferred between CPU and RAM in a single operation.

The hardware registers in a computer machine are word sized. The Word size also defines the largest possible memory address (each memory address points to a byte sized memory).

Note – In C++ programs, the memory addresses points to a byte of memory and not to a word.

The best site to test website and see them realtime on MAC Safari is by using

I just get a warning (not an error) that the table exists;

You can combine both in the same date function call

date("d-m-Y H:i:s");

drpCategory.Items.Remove(removeItem);

Replace "TextToFind" with the item you want to remove.

If you check a cluster using NIS, the only way to see if a user has a crontab entry ist according to Matt's answer /var/spool/cron/tabs.

grep -v "#" -R  /var/spool/cron/tabs

inside the Form, You can use this code. Replace your variable name (i use $variable)

<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">

Report from the future: April 2018.

I wanted to normalize my local repos on my Mac and my Windows, which had ended up in different local folders.

The Windows 10 client made me go through the "Can't Find" > "Locate" routine, tedious but not terrible. Also need to update the local "Clone path" in Options for future use.

When I consolidated the mac folders, the Github client just found them again - I had to do nothing!

If you have a browser that doesn't support the calc expression, it's not hard to mimic with jQuery:

$('#yourEl').css('width', '100%').css('width', '-=100px');

It's much easier to let jQuery handle the relative calculation than doing it yourself.

If there is an on-screen keyboard, focusing a text field that is near the bottom of the viewport will cause Safari to scroll the text field into view. There might be some way to exploit this phenomenon to detect the presence of the keyboard (having a tiny text field at the bottom of the page which gains focus momentarily, or something like that).

SUBSTR will be better than FLOOR in some cases because FLOOR has a "bug" as follow:

SELECT 25 * 9.54 + 0.5 -> 239.00

SELECT FLOOR(25 * 9.54 + 0.5) -> 238  (oops!)

SELECT SUBSTR((25*9.54+0.5),1,LOCATE('.',(25*9.54+0.5)) - 1) -> 239

You can do it by making form and displaying it using ShowDialogBox....

Form.ShowDialog Method - Shows the form as a modal dialog box.

Example:

public void ShowMyDialogBox()
{
   Form2 testDialog = new Form2();

   // Show testDialog as a modal dialog and determine if DialogResult = OK.
   if (testDialog.ShowDialog(this) == DialogResult.OK)
   {
      // Read the contents of testDialog's TextBox.
      this.txtResult.Text = testDialog.TextBox1.Text;
   }
   else
   {
      this.txtResult.Text = "Cancelled";
   }
   testDialog.Dispose();
}

Example for Continue:

number = 0

for number in range(10):
   number = number + 1

   if number == 5:
      continue    # continue here

   print('Number is ' + str(number))

print('Out of loop')

Output:

Number is 1
Number is 2
Number is 3
Number is 4
Number is 6 # Note: 5 is skipped!!
Number is 7
Number is 8
Number is 9
Number is 10
Out of loop

For Next button you can use xpath or cssSelector as below:

xpath for Next button: //input[@value='Next']

cssPath for Next button: input[value=Next]

In simple words, dereferencing means accessing the value from a certain memory location against which that pointer is pointing.

Nowadays your compiler should do all the work for you. At least of what I know gcc is very efficient in optimizing calls to memset away (better check the assembler, though).

Then also, avoid memset if you don't have to:

• use calloc for heap memory
• use proper initialization (... = { 0 }) for stack memory

And for really large chunks use mmap if you have it. This just gets zero initialized memory from the system "for free".

When most people think of functions, they think of named functions:

function foo() { return "This string is returned from the 'foo' function"; }

These are called by name, of course:

foo(); //returns the string above

With lambda expressions, you can have anonymous functions:

 @foo = lambda() {return "This is returned from a function without a name";}

With the above example, you can call the lambda through the variable it was assigned to:

foo();

More useful than assigning anonymous functions to variables, however, are passing them to or from higher-order functions, i.e., functions that accept/return other functions. In a lot of these cases, naming a function is unecessary:

function filter(list, predicate) 
 { @filteredList = [];
   for-each (@x in list) if (predicate(x)) filteredList.add(x);
   return filteredList;
 }

//filter for even numbers
filter([0,1,2,3,4,5,6], lambda(x) {return (x mod 2 == 0)}); 

A closure may be a named or anonymous function, but is known as such when it "closes over" variables in the scope where the function is defined, i.e., the closure will still refer to the environment with any outer variables that are used in the closure itself. Here's a named closure:

@x = 0;

function incrementX() { x = x + 1;}

incrementX(); // x now equals 1

That doesn't seem like much but what if this was all in another function and you passed incrementX to an external function?

function foo()
 { @x = 0;

   function incrementX() 
    { x = x + 1;
      return x;
    }

   return incrementX;
 }

@y = foo(); // y = closure of incrementX over foo.x
y(); //returns 1 (y.x == 0 + 1)
y(); //returns 2 (y.x == 1 + 1)

This is how you get stateful objects in functional programming. Since naming "incrementX" isn't needed, you can use a lambda in this case:

function foo()
 { @x = 0;

   return lambda() 
           { x = x + 1;
             return x;
           };
 }

Just to spell out something explicitly:

The main thread is basically the UI thread.

So saying that you cannot do networking operations in the main thread means you cannot do networking operations in the UI thread, which means you cannot do networking operations in a *runOnUiThread(new Runnable() { ... }* block inside some other thread, either.

(I just had a long head-scratching moment trying to figure out why I was getting that error somewhere other than my main thread. This was why; this thread helped; and hopefully this comment will help someone else.)

The JQuery code is fine. You must execute in the ready handler not in the window load event.

<script type="text/javascript">
$(function(){
  var aspForm  = $("form#aspnetForm");
  var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm);
  firstInput.focus();
});
</script>

Update

I tried with the example of Karim79(thanks for the example) and it works fine: http://jsfiddle.net/2sMfU/

1. In my case I just close the app form emulator

2. Then run this again

react-native run-android

Or since Objective C is just C with some OO layer on top you can use the posix conterparts:

int execl(const char *path, const char *arg0, ..., const char *argn, (char *)0);
int execle(const char *path, const char *arg0, ..., const char *argn, (char *)0, char *const envp[]);
int execlp(const char *file, const char *arg0, ..., const char *argn, (char *)0);
int execlpe(const char *file, const char *arg0, ..., const char *argn, (char *)0, char *const envp[]);
int execv(const char *path, char *const argv[]);
int execve(const char *path, char *const argv[], char *const envp[]);
int execvp(const char *file, char *const argv[]);
int execvpe(const char *file, char *const argv[], char *const envp[]); 

They are included from unistd.h header file.

For AspNetCore, it looks like this:

if(s==r)
$(div).appendTo($(".target")); 
++S;
});

});

});

});

You can use the index method available on Array with a predicate (see Apple's documentation here).

func index(where predicate: (Element) throws -> Bool) rethrows -> Int?

For your specific example this would be:

Swift 5.0

if let i = array.firstIndex(where: { $0.name == "Foo" }) {
    return array[i]
}

Swift 3.0

if let i = array.index(where: { $0.name == Foo }) {
    return array[i]
}

Swift 2.0

if let i = array.indexOf({ $0.name == Foo }) {
    return array[i]
}

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)
                .OrderBy(w => w.Frequency);

For the distributed portion, you could check out DryadLINQ: http://research.microsoft.com/en-us/projects/dryadlinq/default.aspx

The error happens because of you are trying to map a numeric vector to data in geom_errorbar: GVW[1:64,3]. ggplot only works with data.frame.

In general, you shouldn't subset inside ggplot calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame and you will be able to plot everything in one call.

Here with a dplyr solution to summarise the data and compute the standard error beforehand.

library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
    summarise(mean = mean(value),se = sd(value) / sqrt(n()))

ggplot(d, aes(x = variable, y = mean, fill = Genotype)) + 
  geom_bar(position = position_dodge(), stat = "identity", 
      colour="black", size=.3) +
  geom_errorbar(aes(ymin = mean - se, ymax = mean + se), 
      size=.3, width=.2, position=position_dodge(.9)) +
  xlab("Time") +
  ylab("Weight [g]") +
  scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"), 
      labels = c("Knock-out", "Wild type")) +
  ggtitle("Effect of genotype on weight-gain") +
  scale_y_continuous(breaks = 0:20*4) +
  theme_bw()

if (string.IsNullOrWhiteSpace(fileName)) return Content("filename not present");

        var path = Path.Combine(your path, your filename);

        var stream = new FileStream(path, FileMode.Open);

        return File(stream, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);

Manually changing XML and/or settings is very dangerous in eclipse unless you know exactly what you're doing. In the other case you might end up finding your complete project is screwed. Taking a backup is very recommended!

How to do it just using Eclipse?

1. Select project.
2. Open the project properties through Project -> Properties.
3. Go to "Targetted Runtimes" and add the proper runtime. Click APPLY.
4. Go to "Project Facets" and select the JAVA facet which has appeared due to step 4. Click APPLY
5. Set your build path.
6. If it's a Maven project, you might want to select the project, click Maven -> Update Project configuration...

That did it for me. And Eclipse is configured correctly. Hope it'll work for you too.

I have answered this question here: https://stackoverflow.com/a/38238785/1773972

Basically use

StringUtils.substringBetween(str, "<%=", "%>");

This requirs using "Apache commons lang" library: https://mvnrepository.com/artifact/org.apache.commons/commons-lang3/3.4

This library has a lot of useful methods for working with string, you will really benefit from exploring this library in other areas of your java code !!!

Unfortunately I can't comment the answer from geza.

He is not just saying "put forward declarations into a separate header". He says that you have to spilt class definition headers and inline function definitions into different header files to allow "defered dependencies".

But his illustration is not really good. Because both classes (A and B) only need an incomplete type of each other (pointer fields / parameters).

To understand it better imagine that class A has a field of type B not B*. In addition class A and B want to define an inline function with parameters of the other type:

This simple code would not work:

// A.h
#pragme once
#include "B.h"

class A{
  B b;
  inline void Do(B b);
}

inline void A::Do(B b){
  //do something with B
}

// B.h
#pragme once
class A;

class B{
  A* b;
  inline void Do(A a);
}

#include "A.h"

inline void B::Do(A a){
  //do something with A
}

//main.cpp
#include "A.h"
#include "B.h"

It would result in the following code:

//main.cpp
//#include "A.h"

class A;

class B{
  A* b;
  inline void Do(A a);
}

inline void B::Do(A a){
  //do something with A
}

class A{
  B b;
  inline void Do(B b);
}

inline void A::Do(B b){
  //do something with B
}
//#include "B.h"

This code does not compile because B::Do needs a complete type of A which is defined later.

To make sure that it compiles the source code should look like this:

//main.cpp
class A;

class B{
  A* b;
  inline void Do(A a);
}

class A{
  B b;
  inline void Do(B b);
}

inline void B::Do(A a){
  //do something with A
}

inline void A::Do(B b){
  //do something with B
}

This is exactly possible with these two header files for each class wich needs to define inline functions. The only issue is that the circular classes can't just include the "public header".

To solve this issue I would like to suggest a preprocessor extension: #pragma process_pending_includes

This directive should defer the processing of the current file and complete all pending includes.

The way I figured this out was going through the example index.html/style.css that comes packaged with the Fancybox installation.

If you view the code that is used for the demo website and basically copy/paste, you'll be fine.

To get an inline Fancybox working, you will need to have this code present in your index.html file:

  <head>
    <link href="./fancybox/jquery.fancybox-1.3.4.css" rel="stylesheet" type="text/css" media="screen" />
    <script>!window.jQuery && document.write('<script src="jquery-1.4.3.min.js"><\/script>');</script>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
    <script type="text/javascript" src="./fancybox/jquery.fancybox-1.3.4.pack.js"></script>
    <script type="text/javascript">
    $(document).ready(function() {

    $("#various1").fancybox({
            'titlePosition'     : 'inside',
            'transitionIn'      : 'none',
            'transitionOut'     : 'none'
        });
    });
    </script>
  </head>

 <body>

    <a id="various1" href="#inline1" title="Put a title here">Name of Link Here</a>
    <div style="display: none;">
        <div id="inline1" style="width:400px;height:100px;overflow:auto;">
                   Write whatever text you want right here!!
        </div>
    </div> 

</body>

Remember to be precise about what folders your script files are placed in and where you are pointing to in the Head tag; they must correspond.

The answer is "no, you probably can't".

While there is stuff in there that might say who created a given object, there are a lot of "ifs" behind them. A quick (and not necessarily complete) review:

sys.objects (and thus sys.tables, sys.procedures, sys.views, etc.) has column principal_id. This value is a foreign key that relates to the list of database users, which in turn can be joined with the list of SQL (instance) logins. (All of this info can be found in further system views.)

But.

A quick check on our setup here and a cursory review of BOL indicates that this value is only set (i.e. not null) if it is "different from the schema owner". In our development system, and we've got dbo + two other schemas, everything comes up as NULL. This is probably because everyone has dbo rights within these databases.

This is using NT authentication. SQL authentication probably works much the same. Also, does everyone have and use a unique login, or are they shared? If you have employee turnover and domain (or SQL) logins get dropped, once again the data may not be there or may be incomplete.

You can look this data over (select * from sys.objects), but if principal_id is null, you are probably out of luck.

Test it yourself, but here's the output.

php -r '$a=array("a","b","c"); print_r($a); unset($a[1]); print_r($a);'
Array
(
    [0] => a
    [1] => b
    [2] => c
)
Array
(
    [0] => a
    [2] => c
)

Thanks for the tips guys. Will definitely keep them in mind when I need to rest the key pairs. However, in the interest of efficiency and laziness I've come up with something else:

1. Create your new key pair and download the credentials
2. Right-click your instance > Create AMI Once it is done
3. terminate your instance (or just stop it until you are sure you can create another one from your new shiny AMI)
4. Start a new EC2 instance from the AMI you just created and specify your new key pair created in step (1) above.

Hope this can be of use to you and save you some time as well as minimize the amount of white hair you get from stuff like this :)

Method 1 ( for multiserver )

First , lets make a backup of original config.

sudo cp /etc/phpmyadmin/config.inc.php      ~/ 

Now in /usr/share/doc/phpmyadmin/examples/ you will see a file config.manyhosts.inc.php. Just copy in to /etc/phpmyadmin/ using command bellow:

sudo cp /usr/share/doc/phpmyadmin/examples/config.manyhosts.inc.php \
        /etc/phpmyadmin/config.inc.php

Edit the config.inc.php

sudo nano /etc/phpmyadmin/config.inc.php 

Search for :

$hosts = array (
    "foo.example.com",
    "bar.example.com",
    "baz.example.com",
    "quux.example.com",
);

And add your ip or hostname array save ( in nano CTRL+X press Y ) and exit . Done

Method 2 ( single server ) Edit the config.inc.php

sudo nano /etc/phpmyadmin/config.inc.php 

Search for :

/* Server parameters */
if (empty($dbserver)) $dbserver = 'localhost';
$cfg['Servers'][$i]['host'] = $dbserver;

if (!empty($dbport) || $dbserver != 'localhost') {
    $cfg['Servers'][$i]['connect_type'] = 'tcp';
    $cfg['Servers'][$i]['port'] = $dbport;
}

And replace with:

$cfg['Servers'][$i]['host'] = '192.168.1.100';
$cfg['Servers'][$i]['port'] = '3306';

Remeber to replace 192.168.1.100 with your own mysql ip server.

Sorry for my bad English ( google translate have the blame :D )

Guido has a good explanation of this here. Here's the most relevant part:

I have never considered Python to be heavily influenced by functional languages, no matter what people say or think. I was much more familiar with imperative languages such as C and Algol 68 and although I had made functions first-class objects, I didn't view Python as a functional programming language. However, earlier on, it was clear that users wanted to do much more with lists and functions.

...

It is also worth noting that even though I didn't envision Python as a functional language, the introduction of closures has been useful in the development of many other advanced programming features. For example, certain aspects of new-style classes, decorators, and other modern features rely upon this capability.

Lastly, even though a number of functional programming features have been introduced over the years, Python still lacks certain features found in “real” functional programming languages. For instance, Python does not perform certain kinds of optimizations (e.g., tail recursion). In general, because Python's extremely dynamic nature, it is impossible to do the kind of compile-time optimization known from functional languages like Haskell or ML. And that's fine.

I pull two things out of this:

1. The language's creator doesn't really consider Python to be a functional language. Therefore, it's possible to see "functional-esque" features, but you're unlikely to see anything that is definitively functional.
2. Python's dynamic nature inhibits some of the optimizations you see in other functional languages. Granted, Lisp is just as dynamic (if not more dynamic) as Python, so this is only a partial explanation.

I didnt try Sumama Waheed's answer but what worked for me was replacing the bin/catalina.jar with a working jar (I disposed of an older tomcat) and after adding in NetBeans, I put the original catalina.jar again.

For some Distributions, Cauchy I think, I have found that trapz will overestimate the area, and so the pdf will change depending on the number of bins you select. In which case I do

[N,h]=hist(q_f./theta,30000); % there Is a large range but most of the bins will be empty
plot(h,N/(sum(N)*mean(diff(h))),'+r')

Try using following command it work.

mysql --user=root --password=root_password

dic0.update(dic1)

Note this doesn't actually return the combined dictionary, it just mutates dic0.

Since you installed a new OS you probably don't have any more of your private and public keys that you used to sign your app in to XCode before. You need to regenerate those keys on your machine by revoking your previous certificate and asking for a new one on the iOS development portal. As part of the process you will be asked to generate a Certificate Signing Request which is where you seem to have a problem.

You will find all you need there which consists of (from the official doc):

1.Open Keychain Access on your Mac (located in Applications/Utilities).

2.Open Preferences and click Certificates. Make sure both Online Certificate Status Protocol and Certificate Revocation List are set to Off.

3.Choose Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority.

Note: If you have a private key selected when you do this, the CSR won’t be accepted. Make sure no private key is selected. Enter your user email address and common name. Use the same address and name as you used to register in the iOS Developer Program. No CA Email Address is required.

4.Select the options “Saved to disk” and “Let me specify key pair information” and click Continue.

5.Specify a filename and click Save. (make sure to replace .certSigningRequest with .csr)

For the Key Size choose 2048 bits and for Algorithm choose RSA. Click Continue and the Certificate Assistant creates a CSR and saves the file to your specified location.

git pull origin master

this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.

How about formatting your configuration as JSON, and using a library like jsoncpp?

e.g.

{"url": "http://mysite dot com",
"file": "main.exe",
"true": 0}

You can then read it into named variables, or even store it all in a std::map, etc. The latter means you can add options without having to change and recompile your configuration parser.

Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()

    fmt.Println("now:", now)

    count := 10
    then := now.Add(time.Duration(-count) * time.Minute)
    // if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
    // then := now.Add(-10 * time.Minute)
    fmt.Println("10 minutes ago:", then)
}

Produces:

now: 2009-11-10 23:00:00 +0000 UTC
10 minutes ago: 2009-11-10 22:50:00 +0000 UTC

Not to mention, you can also use time.Hour or time.Second instead of time.Minute as per your needs.

Playground: https://play.golang.org/p/DzzH4SA3izp

In your eclipse.ini file simply put

–vm
/home/aniket/jdk1.7.0_11/bin(Your path to JDK 7)

before -vmargs line.

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

Another alternative way to achieve the same is to use the tail calls. But, we don’t have anything like that in JavaScript. So generally, the goto is accomplished in JS using the below two keywords. break and continue, reference: Goto Statement in JavaScript

Here is an example:

var number = 0;
start_position: while(true) {
document.write("Anything you want to print");
number++;
if(number < 100) continue start_position;
break;
}

Making a class abstract sends a message to the readers of your code that you want users of your abstract class to subclass it. However, this is not what you want then to do: a utility class should not be subclassed.

Therefore, adding a private constructor is a better choice here. You should also make the class final to disallow subclassing of your utility class.

CREATE TABLE some_table (
  field1 int(11) NOT NULL AUTO_INCREMENT,
  field2 varchar(10) NOT NULL,
  field3 varchar(10) NOT NULL,
  PRIMARY KEY (`field1`)
);

INSERT INTO `some_table` (field1, field2, field3) VALUES
(1, 'text one', 'foo'),
(2, 'text two', 'bar'),
(3, 'text three', 'data'),
(4, 'text four', 'magic');

This query is a bit strange but it does not need another query to initialize the variable; and it can be embedded in a more complex query. It returns all the 'field2's separated by a semicolon.

SELECT result
FROM   (SELECT @result := '',
               (SELECT result
                FROM   (SELECT @result := CONCAT_WS(';', @result, field2) AS result,
                               LENGTH(@result)                            AS blength
                        FROM   some_table
                        ORDER  BY blength DESC
                        LIMIT  1) AS sub1) AS result) AS sub2; 

I had the same problem as you a while back. I can't remember the details but the following code got things working for me. This code is used within a Spring Webflow flow, hence the RequestContext and ExternalContext classes. But the part that is most relevant to you is the doAutoLogin method.

public String registerUser(UserRegistrationFormBean userRegistrationFormBean,
                           RequestContext requestContext,
                           ExternalContext externalContext) {

    try {
        Locale userLocale = requestContext.getExternalContext().getLocale();
        this.userService.createNewUser(userRegistrationFormBean, userLocale, Constants.SYSTEM_USER_ID);
        String emailAddress = userRegistrationFormBean.getChooseEmailAddressFormBean().getEmailAddress();
        String password = userRegistrationFormBean.getChoosePasswordFormBean().getPassword();
        doAutoLogin(emailAddress, password, (HttpServletRequest) externalContext.getNativeRequest());
        return "success";

    } catch (EmailAddressNotUniqueException e) {
        MessageResolver messageResolvable 
                = new MessageBuilder().error()
                                      .source(UserRegistrationFormBean.PROPERTYNAME_EMAIL_ADDRESS)
                                      .code("userRegistration.emailAddress.not.unique")
                                      .build();
        requestContext.getMessageContext().addMessage(messageResolvable);
        return "error";
    }

}


private void doAutoLogin(String username, String password, HttpServletRequest request) {

    try {
        // Must be called from request filtered by Spring Security, otherwise SecurityContextHolder is not updated
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
        token.setDetails(new WebAuthenticationDetails(request));
        Authentication authentication = this.authenticationProvider.authenticate(token);
        logger.debug("Logging in with [{}]", authentication.getPrincipal());
        SecurityContextHolder.getContext().setAuthentication(authentication);
    } catch (Exception e) {
        SecurityContextHolder.getContext().setAuthentication(null);
        logger.error("Failure in autoLogin", e);
    }

}

DELETE FROM table WHERE date < '2011-09-21 08:21:22';

Use innerText/textContent:

  var el = document.getElementById('*spaM4');
  console.log(el.innerText || el.textContent);

Fiddle: http://jsfiddle.net/NeTgC/2/

What about:

def dict_merge_and_sum( d1, d2 ):
    ret = d1
    ret.update({ k:v + d2[k] for k,v in d1.items() if k in d2 })
    ret.update({ k:v for k,v in d2.items() if k not in d1 })
    return ret

A = {'a': 1, 'b': 2, 'c': 3}
B = {'b': 3, 'c': 4, 'd': 5}

print( dict_merge_and_sum( A, B ) )

Output:

{'d': 5, 'a': 1, 'c': 7, 'b': 5}

I've just succeeded!

1. Copy the mylib-0.1.aar file into the libs/ folder

2. Add these lines to the bottom of build.gradle (should be app, not project):

   repositories {
      flatDir {
          dirs 'libs'
      }
   }
   dependencies {
       compile 'com.example.lib:mylib:0.1@aar'
   }
   

3. So far so good. Here comes the most important point:

Gradle needs to access the network for dependencies unless offline mode is enabled.

Make sure that you have enabled Offline work via the checkbox in Project Structures/Gradle

-- OR --

Configure the proxy settings in order to access the network.

To configure the proxy settings you have to modify the project's gradle.properties file, configuring http and https separately as below:

systemProp.http.proxyHost=proxy.example.com
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=user
systemProp.http.proxyPassword=pass
systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=example <for NT auth>

systemProp.https.proxyHost=proxy.example.com
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=user
systemProp.https.proxyPassword=pass
systemProp.https.nonProxyHosts=localhost
systemProp.https.auth.ntlm.domain=example <for NT auth>

Hope this works.

You're almost there. Use the following regex (with multi-line option enabled)

\bObject Name:\s+(.*)$

The complete match would be

Object Name:   D:\ApacheTomcat\apache-tomcat-6.0.36\logs\localhost.2013-07-01.log

while the captured group one would contain

D:\ApacheTomcat\apache-tomcat-6.0.36\logs\localhost.2013-07-01.log

If you want to capture the file path directly use

(?m)(?<=\bObject Name:).*$

This doesn't need jquery, doesn't need to load the script async, needs no timer nor to have the loaded script set a value. I've tested it in FF, Chrome, and Safari.

<script>
        function loadScript(src) {
          return new Promise(function(resolve, reject) {

            let s = window.document.createElement("SCRIPT");

            s.onload = () => resolve(s);
            s.onerror = () => reject(new Error(src));
            s.src = src;
            // don't bounce to global handler on 404.
            s.addEventListener('error', function() {});

I haven't used it myself, but another free one that I've heard good thing about is Smultron.

In my own research on this, I found this interesting article: Faceoff: Which Is The Best Mac Text Editor Ever?

You can pass the tv_sec parameter to some of the formatting function. Have a look at gmtime, localtime(). Then look at snprintf.

An answer from 2020. The following code solves this. A lot of people new to selenium seem to have to get past this step. Install the chromedriver and put it inside a folder on your desktop. Also make sure to put the selenium python project in the same folder as where the chrome driver is located.

Change USER_NAME and FOLDER in accordance to your computer.

For Windows

driver = webdriver.Chrome(r"C:\Users\USER_NAME\Desktop\FOLDER\chromedriver")

For Linux/Mac

driver = webdriver.Chrome("/home/USER_NAME/FOLDER/chromedriver")

In C, this is done using arguments passed to your main() function:

int main(int argc, char *argv[])
{
    int i = 0;
    for (i = 0; i < argc; i++) {
        printf("argv[%d] = %s\n", i, argv[i]);
    }
    return 0;
}

More information can be found online such as this Arguments to main article.

One more solution: when the files get locked, blocking process is reported (something like "ServiceHub.Host.CLR.x64 (7764)") with it's id in parentheses. To get rid of the process, open PowerShell (x + Win + I) and type: "Stop-Process -Id idNumber".

Add multiple connection strings in your web.config or app.config.

Then you can get them as a string like :

System.Configuration.ConfigurationManager.
    ConnectionStrings["entityFrameworkConnection"].ConnectionString;

Then use the string to set :

Provider
Metadata
ProviderConnectionString

It is better explained here :

Read connection string from web.config

I'd use datediff, and not care about format conversions:

SELECT *
FROM   mytable
WHERE  DATEDIFF(MONTH, my_date_column, GETDATE()) <= 3

This is my working version. Note that the resolvers code is not shown but are a spin on my implementation which allows columns to be resolved even though they are named slightly differently in each worksheet.

public static IEnumerable<T> ToArray<T>(this ExcelWorksheet worksheet, List<PropertyNameResolver> resolvers) where T : new()
{

  // List of all the column names
  var header = worksheet.Cells.GroupBy(cell => cell.Start.Row).First();

  // Get the properties from the type your are populating
  var properties = typeof(T).GetProperties().ToList();


  var start = worksheet.Dimension.Start;
  var end = worksheet.Dimension.End;

  // Resulting list
  var list = new List<T>();

  // Iterate the rows starting at row 2 (ie start.Row + 1)
  for (int row = start.Row + 1; row <= end.Row; row++)
  {
    var instance = new T();
    for (int col = start.Column; col <= end.Column; col++)
    {
      object value = worksheet.Cells[row, col].Text;

      // Get the column name zero based (ie col -1)
      var column = (string)header.Skip(col - 1).First().Value;

      // Gets the corresponding property to set
      var property = properties.Property(resolvers, column);

      try
      {
        var propertyName = property.PropertyType.IsGenericType
          ? property.PropertyType.GetGenericArguments().First().FullName
          : property.PropertyType.FullName;


        // Implement setter code as needed. 
        switch (propertyName)
        {
          case "System.String":
            property.SetValue(instance, Convert.ToString(value));
            break;
          case "System.Int32":
            property.SetValue(instance, Convert.ToInt32(value));
            break;
          case "System.DateTime":
            if (DateTime.TryParse((string) value, out var date))
            {
              property.SetValue(instance, date);
            }
            property.SetValue(instance, FromExcelSerialDate(Convert.ToInt32(value)));
            break;
          case "System.Boolean":
            property.SetValue(instance, (int)value == 1);
            break;
        }
      }
      catch (Exception e)
      {
        // instance property is empty because there was a problem.
      }

    } 
    list.Add(instance);
  }
  return list;
}

// Utility function taken from the above post's inline function.
public static DateTime FromExcelSerialDate(int excelDate)
{
  if (excelDate < 1)
    throw new ArgumentException("Excel dates cannot be smaller than 0.");

  var dateOfReference = new DateTime(1900, 1, 1);

  if (excelDate > 60d)
    excelDate = excelDate - 2;
  else
    excelDate = excelDate - 1;
  return dateOfReference.AddDays(excelDate);
}

import java.io.*;

private void stringToFile( String text, String fileName )
 {
 try
 {
    File file = new File( fileName );

    // if file doesnt exists, then create it 
    if ( ! file.exists( ) )
    {
        file.createNewFile( );
    }

    FileWriter fw = new FileWriter( file.getAbsoluteFile( ) );
    BufferedWriter bw = new BufferedWriter( fw );
    bw.write( text );
    bw.close( );
    //System.out.println("Done writing to " + fileName); //For testing 
 }
 catch( IOException e )
 {
 System.out.println("Error: " + e);
 e.printStackTrace( );
 }
} //End method stringToFile

You can insert this method into your classes. If you are using this method in a class with a main method, change this class to static by adding the static key word. Either way you will need to import java.io.* to make it work otherwise File, FileWriter and BufferedWriter will not be recognized.

We can use summary on factor column:

summary(myDF$factorColumn)

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

Working demo: https://jsfiddle.net/jfriend00/t17vz506/

jQuery.val() and .text() will never return 'undefined' for an empty selection. It always returns an empty string (i.e. ""). .html() will return null if the element doesn't exist though.You need to do:

if(page_name != '')

For other variables that don't come from something like jQuery.val() you would do this though:

if(typeof page_name != 'undefined')

You just have to use the typeof operator.

I think what you want is this:

last_list=[]
if p.last_name != None and p.last_name != "":
    last_list.append(p.last_name)
print last_list

Your current if statement:

if p.last_name == None or p.last_name == "":
    pass

Effectively never does anything. If p.last_name is none or the empty string, it does nothing inside the loop. If p.last_name is something else, the body of the if statement is skipped.

Also, it looks like your statement pan_list.append(p.last) is a typo, because I see neither pan_list nor p.last getting used anywhere else in the code you have posted.

The syntax of if block is as below,

if(condition){
// Executes when condition evaluates to true.
}
else{
// Executes when condition evaluates to false.
}

In your case you are directly passing a boolean value so no evaluation is required.

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

Unfortunately, there is no good, portable way to do this that I know of. If you attempt to parse /etc/group, as others are suggesting, you will miss users who have that group as their primary group and anyone who has been added to that group via a mechanism other than UNIX flat files (i.e. LDAP, NIS, pam-pgsql, etc.).

If I absolutely had to do this myself, I'd probably do it in reverse: use id to get the groups of every user on the system (which will pull all sources visible to NSS), and use Perl or something similar to maintain a hash table for each group discovered noting the membership of that user.

Edit: Of course, this leaves you with a similar problem: how to get a list of every user on the system. Since my location uses only flat files and LDAP, I can just get a list from both locations, but that may or may not be true for your environment.

Edit 2: Someone in passing reminded me that getent passwd will return a list of all users on the system including ones from LDAP/NIS/etc., but getent group still will still miss users that are members only via the default group entry, so that inspired me to write this quick hack.

You cannot do this in any released version of C#, nor in the upcoming C# 4.0. It's not a C# limitation, either - there's no "interface" constraint in the CLR itself.

How about subtracting one and changing Sunday

IF(DAYOFWEEK() = 1, 7, DAYOFWEEK() - 1)

Of course you would have to do this for every query.

You can use a regex like this to extract normal url patterns.

(https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}|www\.[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}|https?:\/\/(?:www\.|(?!www))[a-zA-Z0-9]+\.[^\s]{2,}|www\.[a-zA-Z0-9]+\.[^\s]{2,})

If you need more sophisticated patterns, use a library like this.

It is possible to do (in the deployed repository)

git fetch
git checkout origin/master -- path/to/file

The fetch will download all the recent changes, but it will not put it in your current checked out code (working area).

The checkout will update the working tree with the particular file from the downloaded changes (origin/master).

At least this works for me for those little small typo fixes, where it feels weird to create a branch etc just to change one word in a file.

Sometimes Java generics just doesn't let you do what you want to, and you need to effectively tell the compiler that what you're doing really will be legal at execution time.

I usually find this a pain when I'm mocking a generic interface, but there are other examples too. It's usually worth trying to work out a way of avoiding the warning rather than suppressing it (the Java Generics FAQ helps here) but sometimes even if it is possible, it bends the code out of shape so much that suppressing the warning is neater. Always add an explanatory comment in that case!

The same generics FAQ has several sections on this topic, starting with "What is an "unchecked" warning?" - it's well worth a read.

When you add the const keyword to a method the this pointer will essentially become a pointer to const object, and you cannot therefore change any member data. (Unless you use mutable, more on that later).

The const keyword is part of the functions signature which means that you can implement two similar methods, one which is called when the object is const, and one that isn't.

#include <iostream>

class MyClass
{
private:
    int counter;
public:
    void Foo()
    { 
        std::cout << "Foo" << std::endl;    
    }

    void Foo() const
    {
        std::cout << "Foo const" << std::endl;
    }

};

int main()
{
    MyClass cc;
    const MyClass& ccc = cc;
    cc.Foo();
    ccc.Foo();
}

This will output

Foo
Foo const

In the non-const method you can change the instance members, which you cannot do in the const version. If you change the method declaration in the above example to the code below you will get some errors.

    void Foo()
    {
        counter++; //this works
        std::cout << "Foo" << std::endl;    
    }

    void Foo() const
    {
        counter++; //this will not compile
        std::cout << "Foo const" << std::endl;
    }

This is not completely true, because you can mark a member as mutable and a const method can then change it. It's mostly used for internal counters and stuff. The solution for that would be the below code.

#include <iostream>

class MyClass
{
private:
    mutable int counter;
public:

    MyClass() : counter(0) {}

    void Foo()
    {
        counter++;
        std::cout << "Foo" << std::endl;    
    }

    void Foo() const
    {
        counter++;    // This works because counter is `mutable`
        std::cout << "Foo const" << std::endl;
    }

    int GetInvocations() const
    {
        return counter;
    }
};

int main(void)
{
    MyClass cc;
    const MyClass& ccc = cc;
    cc.Foo();
    ccc.Foo();
    std::cout << "Foo has been invoked " << ccc.GetInvocations() << " times" << std::endl;
}

which would output

Foo
Foo const
Foo has been invoked 2 times

If you have to use the current image and get a darker image then you need to create a new one. Else you can simply reduce the opacity of the .image class and the in the .image:hover you can put a higher value for opacity. But then the image without hover would look pale.

The best way would be to create two images and add the following :

.image {
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook.png');
    width: 58px;
    height: 58px;
    opacity:0.9;   
}
.image:hover{
    background: url('http://cdn1.iconfinder.com/data/icons/round-simple-social-icons/58/facebook_hover.png');
}
}

I made this variation of gnarf's solution, so the call and the result is similar to PHP:

function S_GET(id){
    var a = new RegExp(id+"=([^&#=]*)");
    return decodeURIComponent(a.exec(window.location.search)[1]);
}

But as being called in a function slows the process, its better to use as global:

window['var_name'] = decodeURIComponent( /var_in_get=([^&#=]*)/.exec(window.location.search)[1] );

UPDATE

As I'm still learning JS, I created a better answer in a more JS behaviour:

Url = {
    get get(){
        var vars= {};
        if(window.location.search.length!==0)
            window.location.search.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value){
                key=decodeURIComponent(key);
                if(typeof vars[key]==="undefined") {vars[key]= decodeURIComponent(value);}
                else {vars[key]= [].concat(vars[key], decodeURIComponent(value));}
            });
        return vars;
    }
};

This allows to be called just using Url.get.

Example The url ?param1=param1Value&param2=param2Value can be called like:

Url.get.param1 //"param1Value"
Url.get.param2 //"param2Value"

here is a snipet:

// URL GET params_x000D_
url = "?a=2&a=3&b=2&a=4";_x000D_
_x000D_
Url = {_x000D_
    get get(){_x000D_
        var vars= {};_x000D_
        if(url.length!==0)_x000D_
            url.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value){_x000D_
                key=decodeURIComponent(key);_x000D_
                if(typeof vars[key]==="undefined") {vars[key]= decodeURIComponent(value);}_x000D_
                else {vars[key]= [].concat(vars[key], decodeURIComponent(value));}_x000D_
            });_x000D_
        return vars;_x000D_
    }_x000D_
};_x000D_
_x000D_
document.querySelector('log').innerHTML = JSON.stringify(Url.get);

<log></log>

The Array prototype's reverse method modifies the array and returns a reference to it, which means you can do this:

var sortedAsc = _.sortBy(collection, 'propertyName');
var sortedDesc = _.sortBy(collection, 'propertyName').reverse();

Also, the underscore documentation reads:

In addition, the Array prototype's methods are proxied through the chained Underscore object, so you can slip a reverse or a push into your chain, and continue to modify the array.

which means you can also use .reverse() while chaining:

var sortedDescAndFiltered = _.chain(collection)
    .sortBy('propertyName')
    .reverse()
    .filter(_.property('isGood'))
    .value();

I realize this is a very old question, but I stumbled across this problem today and I got it to work with

<div style="text-align:center;">
    <button>button1</button>
    <button>button2</button>
</div>

This answer supposes support for look around! This allowed me to identify all the text between pairs of opening and closing tags. That is all the text between the '>' and the '<'. It works because look around doesn't consume the characters it matches.

(?<=>)([\w\s]+)(?=<\/)

I tested it in https://regex101.com/ using this HTML fragment.

<table>
<tr><td>Cell 1</td><td>Cell 2</td><td>Cell 3</td></tr>
<tr><td>Cell 4</td><td>Cell 5</td><td>Cell 6</td></tr>
</table>

It's a game of three parts: the look behind, the content, and the look ahead.

(?<=>)    # look behind (but don't consume/capture) for a '>'
([\w\s]+) # capture/consume any combination of alpha/numeric/whitespace
(?=<\/)   # look ahead  (but don't consume/capture) for a '</'

I hope that serves as a started for 10. Luck.

We should also consider that the SVM system can be applied directly to non-metric spaces, such as the set of labeled graphs or strings. In fact, the internal kernel function can be generalized properly to virtually any kind of input, provided that the positive definiteness requirement of the kernel is satisfied. On the other hand, to be able to use an ANN on a set of labeled graphs, explicit embedding procedures must be considered.

M-x customize-face RET default will allow you to set the face default face, on which all other faces base on. There you can set the font-size.

Here is what is in my .emacs. actually, color-theme will set the basics, then my custom face setting will override some stuff. the custom-set-faces is written by emacs's customize-face mechanism:

;; my colour theme is whateveryouwant :)
(require 'color-theme)

(color-theme-whateveryouwant)

(custom-set-faces
  ;; custom-set-faces was added by Custom.

clone() was designed with several mistakes (see this question), so it's best to avoid it.

From Effective Java 2nd Edition, Item 11: Override clone judiciously

Given all of the problems associated with Cloneable, it’s safe to say that other interfaces should not extend it, and that classes designed for inheritance (Item 17) should not implement it. Because of its many shortcomings, some expert programmers simply choose never to override the clone method and never to invoke it except, perhaps, to copy arrays. If you design a class for inheritance, be aware that if you choose not to provide a well-behaved protected clone method, it will be impossible for subclasses to implement Cloneable.

This book also describes the many advantages copy constructors have over Cloneable/clone.

• They don't rely on a risk-prone extralinguistic object creation mechanism
• They don't demand unenforceable adherence to thinly documented conventions
• They don't conflict with the proper use of final fields
• They don't throw unnecessary checked exceptions
• They don't require casts.

All standard collections have copy constructors. Use them.

List<Double> original = // some list
List<Double> copy = new ArrayList<Double>(original);

This method zips a folder and adds all of the child files & folders (including empty folders) into the zip file.

void zipFolder(Path sourceDir, Path targetFile) throws IOException {
    ZipDirectoryVisitor zipVisitor = new ZipDirectoryVisitor(sourceDir);
    Files.walkFileTree(sourceDir, zipVisitor);
    FileOutputStream fos = new FileOutputStream(targetFile.toString());
    ZipOutputStream zos = new ZipOutputStream(fos);
    byte[] buffer = new byte[1024];
    for (ZipEntry entry : zipVisitor.getZipEntries()) {
        zos.putNextEntry(entry);
        Path curFile = Paths.get(sourceDir.getParent().toString(), entry.toString());
        if (!curFile.toFile().isDirectory()) {
            FileInputStream in = new FileInputStream(Paths.get(sourceDir.getParent().toString(), entry.toString()).toString());
            int len;
            while ((len = in.read(buffer)) > 0) {
                zos.write(buffer, 0, len);
            }
            in.close();
        }
        zos.closeEntry();
    }
    zos.close();

}

And here is the ZipDirectoryVisitor implementation:

The NVARCHAR2 datatype was introduced by Oracle for databases that want to use Unicode for some columns while keeping another character set for the rest of the database (which uses VARCHAR2). The NVARCHAR2 is a Unicode-only datatype.

One reason you may want to use NVARCHAR2 might be that your DB uses a non-Unicode character set and you still want to be able to store Unicode data for some columns without changing the primary character set. Another reason might be that you want to use two Unicode character set (AL32UTF8 for data that comes mostly from western Europe, AL16UTF16 for data that comes mostly from Asia for example) because different character sets won't store the same data equally efficiently.

Both columns in your example (Unicode VARCHAR2(10 CHAR) and NVARCHAR2(10)) would be able to store the same data, however the byte storage will be different. Some strings may be stored more efficiently in one or the other.

Note also that some features won't work with NVARCHAR2, see this SO question:

• Oracle Text will not work with NVARCHAR2. What else might be unavailable?

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

mdpi is the reference density -- that is, 1 px on an mdpi display is equal to 1 dip. The ratio for asset scaling is:

ldpi | mdpi | hdpi | xhdpi | xxhdpi | xxxhdpi
0.75 | 1    | 1.5  | 2     | 3      | 4

Although you don't really need to worry about tvdpi unless you're developing specifically for Google TV or the original Nexus 7 -- but even Google recommends simply using hdpi assets. You probably don't need to worry about xxhdpi either (although it never hurts, and at least the launcher icon should be provided at xxhdpi), and xxxhdpi is just a constant in the source code right now (no devices use it, nor do I expect any to for a while, if ever), so it's safe to ignore as well.

What this means is if you're doing a 48dip image and plan to support up to xhdpi resolution, you should start with a 96px image (144px if you want native assets for xxhdpi) and make the following images for the densities:

ldpi    | mdpi    | hdpi    | xhdpi     | xxhdpi    | xxxhdpi
36 x 36 | 48 x 48 | 72 x 72 | 96 x 96   | 144 x 144 | 192 x 192

And these should display at roughly the same size on any device, provided you've placed these in density-specific folders (e.g. drawable-xhdpi, drawable-hdpi, etc.)

For reference, the pixel densities for these are:

ldpi  | mdpi  | hdpi  | xhdpi  | xxhdpi  | xxxhdpi
120   | 160   | 240   | 320    | 480     | 640

I assume you want the DER encoded version of your PEM private key.

openssl rsa -outform der -in private.pem -out private.key

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

As answered but to save typing out "2006-01-02T15:04:05.000Z" for the layout, you could use the package's constant RFC3339.

str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(time.RFC3339, str)

if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

    catch (Exception ex)
    {
        obj = null;

If you work with large vectors (size > 100,000) and want to delete lots of elements, I would recommend to do something like this:

int main(int argc, char** argv) {

    vector <int> vec;
    vector <int> vec2;

    for (int i = 0; i < 20000000; i++){
        vec.push_back(i);}

    for (int i = 0; i < vec.size(); i++)
    {
        if(vec.at(i) %3 != 0)
            vec2.push_back(i);
    }

    vec = vec2;
    cout << vec.size() << endl;
}

The code takes every number in vec that can't be divided by 3 and copies it to vec2. Afterwards it copies vec2 in vec. It is pretty fast. To process 20,000,000 elements this algorithm only takes 0.8 sec!

I did the same thing with the erase-method, and it takes lots and lots of time:

Erase-Version (10k elements)  : 0.04 sec
Erase-Version (100k elements) : 0.6  sec
Erase-Version (1000k elements): 56   sec
Erase-Version (10000k elements): ...still calculating (>30 min)

With my T7300 2.0GHz and Kingston V100 64gb SSD the results are

Bitlocker off ? on

Sequential read 243 MB/s ? 140 MB/s

Sequential write 74.5 MB/s ? 51 MB/s

Random read 176 MB/s ? 100 MB/s

Random write, and the 4KB speeds are almost identical.

Clearly the processor is the bottleneck in this case. In real life usage however boot time is about the same, cold launch of Opera 11.5 with 79 tabs remained the same 4 seconds all tabs loaded from cache.

A small build in VS2010 took 2 seconds in both situations. Larger build took 2 seconds vs 5 from before. These are ballpark because I'm looking at my watch hand.

I guess it all depends on the combination of processor, ram, and ssd vs hdd. In my case the processor has no hardware AES so compilation is worst case scenario, needing cycles for both assembly and crypto.

A newer system with Sandy Bridge would probably make better use of a Bitlocker enabled SDD in a development environment.

Personally I'm keeping Bitlocker enabled despite the performance hit because I travel often. It took less than an hour to toggle Bitlocker on/off so maybe you could just turn it on when you are traveling then disable it afterwards.

I tried Ninh Pham's solution but it didn't work for me until I tweaked it - see below. Remove contentType and don't encode your json data

$.fn.postJSON = function(url, data) {
    return $.ajax({
            type: 'POST',
            url: url,
            data: data,
            dataType: 'json'
        });

The way you take a length of anything for which that makes sense (a list, dictionary, tuple, string, ...) is to call len on it.

l = [1,2,3,4]
s = 'abcde'
len(l) #returns 4
len(s) #returns 5

The reason for the "strange" syntax is that internally python translates len(object) into object.__len__(). This applies to any object. So, if you are defining some class and it makes sense for it to have a length, just define a __len__() method on it and then one can call len on those instances.

Not all parameters are supported by all cameras - actually, they are one of the most troublesome part of the OpenCV library. Each camera type - from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of them, but of course not all possibilities are covered.

What you can do is to investigate your camera driver, write a patch for OpenCV and send it to code.opencv.org. This way others will enjoy your work, the same way you enjoy others'.

There is also a possibility that your camera does not support your request - most USB cams are cheap and simple. Maybe that parameter is just not available for modifications.

If you are sure the camera supports a given param (you say the camera manufacturer provides some code) and do not want to mess with OpenCV, you can wrap that sample code in C++ with boost::python, to make it available in Python. Then, enjoy using it.

Perhaps you'll have to check the nodetype too:

if(element.nodeType == 1){//element of type html-object/tag
  if(element.tagName=="a"){
    //this is an a-element
  }
  if(element.tagName=="div"){
    //this is a div-element
  }
}

Edit: Corrected the nodeType-value

With recent changes in brew (deprecation of homebrew/php) you now install php with mcrypt with the following.

A static method belongs to the class itself and a non-static (aka instance) method belongs to each object that is generated from that class. If your method does something that doesn't depend on the individual characteristics of its class, make it static (it will make the program's footprint smaller). Otherwise, it should be non-static.

Example:

class Foo {
    int i;

    public Foo(int i) { 
       this.i = i;
    }

    public static String method1() {
       return "An example string that doesn't depend on i (an instance variable)";
    }

    public int method2() {
       return this.i + 1; // Depends on i
    }
}

You can call static methods like this: Foo.method1(). If you try that with method2, it will fail. But this will work: Foo bar = new Foo(1); bar.method2();

I had this error; it happened somewhat spontaneously, and the page would halt in the browser in the middle of an HTML tag (not a section of code). It was baffling!

Turns out, I let a variable go out of scope and the garbage collector swept it away and then I tried to use it. Thus the seemingly-random timing.

To give a more concrete example... Inside a method, I had something like:

Foo[] foos = new Foo[20];
// fill up the "foos" array...
return Arrays.asList(foos); // this returns type List<Foo>

Now in my JSP page, I called that method and used the List object returned by it. The List object is backed by that "foos" array; but, the array went out of scope when I returned from the method (since it is a local variable). So shortly after returning, the garbage collector swept away the "foos" array, and my access to the List caused a NullPointerException since its underlying array was now wiped away.

I actually wondered, as I wrote the above method, whether that would happen.

The even deeper underlying problem was premature optimization. I wanted a list, but I knew I would have exactly 20 elements, so I figured I'd try to be more efficient than new ArrayList<Foo>(20) which only sets an initial size of 20 but can possibly be less efficient than the method I used. So of course, to fix it, I just created my ArrayList, filled it up, and returned it. No more strange error.

There is a switch a^b/c

If you want to calculate

491 mod 12

then enter 491 press a^b/c then enter 12. Then you will get 40, 11, 12. Here the middle one will be the answer that is 11.

Similarly if you want to calculate 41 mod 12 then find 41 a^b/c 12. You will get 3, 5, 12 and the answer is 5 (the middle one). The mod is always the middle value.

If you are including a library which depends on another library, then the order of inclusion is also important:

g++ -o MyApp MyMain.o -lMyLib1 -lMyLib2

In this case, it is okay if MyLib1 depends on MyLib2. However, if there reverse is true, you will get undefined references.

you can use index to access list elements

List<string> list1 = new List<string>();
list1[0] //for getting the first element of the list

If you want to see the default browser errors being displayed, for example, those triggered by HTML attributes (showing up before any client-code JS treatment):

<input name="o" required="required" aria-required="true" type="text">

You should use the submit event instead of the click event. In this case a popup will be automatically displayed requesting "Please fill out this field". Even with preventDefault:

$('form').on('submit', function(event) {
   event.preventDefault();
   my_form_treatment(this, event);
}); // -> this will show up a "Please fill out this field" pop-up before my_form_treatment

As someone mentioned previously, return false would stop propagation (i.e. if there are more handlers attached to the form submission, they would not be executed), but, in this case, the action triggered by the browser will always execute first. Even with a return false at the end.

So if you want to get rid of these default pop-ups, use the click event on the submit button:

$('form input[type=submit]').on('click', function(event) {
   event.preventDefault();
   my_form_treatment(this, event);
}); // -> this will NOT show any popups related to HTML attributes

Django is designed to be easely used to deliver web pages. If you are not confortable with this perhaps you should use another solution.

I'm writting the root or common operations on the model (to have the same interface) and the others on the controller of the model. If I need an operation from other model I import its controller.

This approach it's enough for me and the complexity of my applications.

Hedde's response is an example that shows the flexibility of django and python itself.

Very interesting question anyway!

We can use case statement Like this

select Name,EmailId,gender=case 
when gender='M' then 'F'
when gender='F' then 'M'
end
 from [dbo].[Employees]

WE can also it as follow.

select Name,EmailId,case gender
when 'M' then 'F'
when 'F' then 'M'
end
 from [dbo].[Employees]

Following code shows current hour and minutes in 'Hour:Minutes' column for us.

SELECT  CONVERT(VARCHAR(5), GETDATE(), 108) + 
(CASE WHEN DATEPART(HOUR, GETDATE()) > 12 THEN ' PM'
    ELSE ' AM'
END) 'Hour:Minutes'

or

SELECT  Format(GETDATE(), 'hh:mm') + 
(CASE WHEN DATEPART(HOUR, GETDATE()) > 12 THEN ' PM'
    ELSE ' AM'
END) 'Hour:Minutes'

The go-uuid library is NOT RFC4122 compliant. The variant bits are not set correctly. There have been several attempts by community members to have this fixed but pull requests for the fix are not being accepted.

You can generate UUIDs using the Go uuid library I rewrote based on the go-uuid library. There are several fixes and improvements. This can be installed with:

go get github.com/twinj/uuid

You can generate random (version 4) UUIDs with:

import "github.com/twinj/uuid"

u := uuid.NewV4()

The returned UUID type is an interface and the underlying type is an array.

The library also generates v1 UUIDs and correctly generates v3 and 5 UUIDs. There are several new methods to help with printing and formatting and also new general methods to create UUIDs based off of existing data.

We can create static constructor

static class StaticParent 
{
  StaticParent() 
  {
    //write your initialization code here

  }

}

and it is always parameter less.

static class StaticParent
{
    static int i =5;
    static StaticParent(int i)  //Gives error
    {
      //write your initialization code here
    }
}

and it doesn't have the access modifier

Change your onCreateOptionsMenu method to return true. To quote the docs:

You must return true for the menu to be displayed; if you return false it will not be shown.

If your page is refreshed on submitting - yes, but only through the querystring: http://www.bloggingdeveloper.com/post/JavaScript-QueryString-ParseGet-QueryString-with-Client-Side-JavaScript.aspx (You must use method "GET" then). Else, you can return its value from the php script.
