Programs & Examples On #Setup deployment

Add the following property:

.c{
    ...
    overflow: hidden;
}

This will force the container to respect the height of all elements within it, regardless of floating elements.

UPDATE

Recently, I was working on a project that required this trick, but needed to allow overflow to show, so instead, you can use a pseudo-element to clear your floats, effectively achieving the same effect while allowing overflow on all elements.

.c:after{
    clear: both;
    content: "";
    display: block;
}

My first post... UDF I managed quickly to compile. Usage: Select 3D range as normal and enclose is into quotation marks like below...

=CountIf3D("'StartSheet:EndSheet'!G16:G878";"Criteria")

Advisably sheets to be adjacent to avoid unanticipated results.

Public Function CountIf3D(SheetstoCount As String, CriteriaToUse As Variant)

     Dim sStarSheet As String, sEndSheet As String, sAddress As String
     Dim lColonPos As Long, lExclaPos As Long, cnt As Long

    lColonPos = InStr(SheetstoCount, ":") 'Finding ':' separating sheets
    lExclaPos = InStr(SheetstoCount, "!") 'Finding '!' separating address from the sheets

    sStarSheet = Mid(SheetstoCount, 2, lColonPos - 2) 'Getting first sheet's name
    sEndSheet = Mid(SheetstoCount, lColonPos + 1, lExclaPos - lColonPos - 2) 'Getting last sheet's name

    sAddress = Mid(SheetstoCount, lExclaPos + 1, Len(SheetstoCount) - lExclaPos) 'Getting address

        cnt = 0
   For i = Sheets(sStarSheet).Index To Sheets(sEndSheet).Index
        cnt = cnt + Application.CountIf(Sheets(i).Range(sAddress), CriteriaToUse)
   Next

   CountIf3D = cnt

End Function

You can simply use replace() function,

with where clause-

update tabelName set columnName=REPLACE(columnName,'from','to') where condition;

without where clause-

update tabelName set columnName=REPLACE(columnName,'from','to');

Note: The above query if for update records directly in table, if you want on select query and the data should not be affected in table then can use the following query-

select REPLACE(columnName,'from','to') as updateRecord;

In my case I was missing "e" on the word "email" as Chad stated above but I see its not the case with you. Please hit the following command to see if everything is pulling as expected.

git config -l

Git has two types of branches: local and remote. To use git pull and git push as you'd like, you have to tell your local branch (my_test) which remote branch it's tracking. In typical Git fashion this can be done in both the config file and with commands.

Commands

Make sure you're on your master branch with

1)git checkout master

then create the new branch with

2)git branch --track my_test origin/my_test

and check it out with

3)git checkout my_test.

You can then push and pull without specifying which local and remote.

However if you've already created the branch then you can use the -u switch to tell git's push and pull you'd like to use the specified local and remote branches from now on, like so:

git pull -u my_test origin/my_test
git push -u my_test origin/my_test

Config

The commands to setup remote branch tracking are fairly straight forward but I'm listing the config way as well as I find it easier if I'm setting up a bunch of tracking branches. Using your favourite editor open up your project's .git/config and add the following to the bottom.

[remote "origin"]
    url = [email protected]:username/repo.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "my_test"]
    remote = origin
    merge = refs/heads/my_test

This specifies a remote called origin, in this case a GitHub style one, and then tells the branch my_test to use it as it's remote.

You can find something very similar to this in the config after running the commands above.

Some useful resources:

• http://www.kernel.org/pub/software/scm/git/docs/git-branch.html
• http://gitready.com/beginner/2009/03/09/remote-tracking-branches.html

You can do it using the plain JavaScript:

function trimString(str, maxLen) {
if (str.length <= maxLen) {
return str;
}
var trimmed = str.substr(0, maxLen);
return trimmed.substr(0, trimmed.lastIndexOf(' ')) + '…';
}

// Let's test it

sentenceOne = "too short";
sentencetwo = "more than the max length";

console.log(trimString(sentenceOne, 15));
console.log(trimString(sentencetwo, 15));

your validation should be occur before your event suppose you are going to submit your form.

anyway if you want this on onchange, so here is code.

function valid(id)
{
    var textVal=document.getElementById(id).value;
    if (!textVal.match(/\S/)) 
    {
        alert("Field is blank");
        return false;
    } 
    else 
    {
        return true;
    }
 }

Usually this is an error in your PHP configuration.

It's actually pretty easy to figure out what exactly is going on:

• Create a small file (test.php) with the standard phpinfo() script
• Open a command prompt
• Start php manually using the small file, e.g. '"\program files\php\php.exe" test.php
• Read the error messages :-)

Like this:

<video width="300" height="200" autoplay="autoplay">
  <source src="video/supercoolvideo.mp4" type="video/mp4" />
</video>

controls is a boolean attribute:

Note: The values "true" and "false" are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether.

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

Take a look at my jquery videoBG plugin

http://syddev.com/jquery.videoBG/

Make any HTML5 video a site background... has an image fallback for browsers that don't support html5

Really easy to use

Let me know if you need any help.

In my taste, it's also very concise to combine zip() with xrange(n) (or range(n) in Python3), which works nice on generators as well and seems to be more flexible for changes in general.

# Option #1: taking the first n elements as a list
[x for _, x in zip(xrange(n), generator)]

# Option #2, using 'next()' and taking care for 'StopIteration'
[next(generator) for _ in xrange(n)]

# Option #3: taking the first n elements as a new generator
(x for _, x in zip(xrange(n), generator))

# Option #4: yielding them by simply preparing a function
# (but take care for 'StopIteration')
def top_n(n, generator):
    for _ in xrange(n): yield next(generator)

this is the best way to solve this

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

With Java 8, the new java.time package should be used.

Objects are immutable, time zones and day light saving are taken into account.

You can create a ZonedDateTime object from an old java.util.Date object like this:

    Date date = new Date();
    ZonedDateTime zonedDateTime = date.toInstant().atZone(ZoneId.systemDefault());

Try this:

twoDec = Math.Round(val, 2)

You can use CFArray instead of NSArray. Here is an article explaining how.

CFMutableArrayRef ar = CFArrayCreateMutable(NULL, 0, NULL);
for (NSUInteger i = 0; i < 1000; i++)
{
  CFArrayAppendValue(ar, (void*)i);
}
CFRelease(ar); /* Releasing the array */

The same applies for the CoreFoundation version of the other containers too.

Other than the answers mentioned above. This will do it. Using Angular 5 and AngularFire2. or use firebase.firestore() instead of this.afs

  // say you have have the following object and 
  // database structure as you mentioned in your post
  data = { who: "[email protected]", when: new Date() };

  ...othercode


  addSharedWith(data) {

    const postDocRef = this.afs.collection('posts').doc('docID');

    postDocRef.subscribe( post => {

      // Grab the existing sharedWith Array
      // If post.sharedWith doesn`t exsit initiated with empty array
      const foo = { 'sharedWith' : post.sharedWith || []};

      // Grab the existing sharedWith Array
      foo['sharedWith'].push(data);

      // pass updated to fireStore
      postsDocRef.update(foo);
      // using .set() will overwrite everything
      // .update will only update existing values, 
      // so we initiated sharedWith with empty array
    });
 }  

OAuth 2.0 defines a protocol, i.e. specifies how tokens are transferred, JWT defines a token format.

OAuth 2.0 and "JWT authentication" have similar appearance when it comes to the (2nd) stage where the Client presents the token to the Resource Server: the token is passed in a header.

But "JWT authentication" is not a standard and does not specify how the Client obtains the token in the first place (the 1st stage). That is where the perceived complexity of OAuth comes from: it also defines various ways in which the Client can obtain an access token from something that is called an Authorization Server.

So the real difference is that JWT is just a token format, OAuth 2.0 is a protocol (that may use a JWT as a token format).

Simplest answer is the following.....

All members in C# always take the LEAST accessible modifier possible by default.

That is why all top level classes in an assembly are "internal" by default, which means they are public to the assembly they are in, but private or excluded from access to outside assemblies. The only other option for a top level class is public which is more accessible. For nested types its all private except for a few rare exceptions like members of enums and interfaces which can only be public. Some examples. In the case of top level classes and interfaces, the defaults are:

class Animal same as internal class Animal

interface Animal same as public interface Animal

In the case of nested classes and interfaces (inside types), the defaults are:

class Animal same as private class Animal

interface Animal same as private interface Animal

If you just assume the default is always the most private, then you do not need to use an accessors until you need to change the default. Easy.

this should work:

svn commit -m "<Your message here>" path/to/your/file

you can also add multiple files like this:

svn commit -m "<Your message here>" path/to/your/file [path/to/your/file] [path/to/your/file]

Updating the value of a field does not update its value attribute in the DOM so that's why your selector is always matching a field, even when it's not actually empty.

Instead use the invalid pseudo-class to achieve what you want, like so:

input:required {_x000D_
  border: 1px solid green;_x000D_
}_x000D_
input:required:invalid {_x000D_
  border: 1px solid red;_x000D_
}

<input required type="text" value="">_x000D_
_x000D_
<input required type="text" value="Value">

Type on sqlplus command prompt

SQL> select * from global_name;

then u will be see result on command prompt

SQL ORCL.REGRESS.RDBMS.DEV.US.ORACLE.COM

Here first one "ORCL" is database name,may be your system "XE" and other what was given on oracle downloading time.

Oracle stores only the fractions up to second in a DATE field.

Use TIMESTAMP instead:

SELECT  TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM    dual

, possibly casting it to a DATE then:

SELECT  CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM    dual

You do not need to use the while True: loop in this case. There is a much simpler way to use the time condition directly:

import time

# timeout variable can be omitted, if you use specific value in the while condition
timeout = 300   # [seconds]

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    test = 0
    if test == 5:
        break
    test -= 1

Change column position:

ALTER TABLE Employees 
   CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;

If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:

ALTER TABLE UserOrder 
   CHANGE order_id order_id INT(11) NOT NULL FIRST;

Use

System.getProperty("java.class.path")

see http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

You can also split it into it's elements easily

String classpath = System.getProperty("java.class.path");
String[] classpathEntries = classpath.split(File.pathSeparator);

In addition to Ishan's answer, if you want to draw programatically without user interaction, you can edit the class just a little like this.

public class DrawingCanvas extends View {

private Paint mPaint;
private Path mPath;
private boolean isUserInteractionEnabled = false;

public DrawingCanvas(Context context, AttributeSet attrs) {
    super(context, attrs);
    mPaint = new Paint();
    mPaint.setColor(Color.RED);
    mPaint.setStyle(Paint.Style.STROKE);
    mPaint.setStrokeJoin(Paint.Join.ROUND);
    mPaint.setStrokeCap(Paint.Cap.ROUND);
    mPaint.setStrokeWidth(10);
    mPath = new Path();
}


@Override
protected void onDraw(Canvas canvas) {
    canvas.drawPath(mPath, mPaint);
    super.onDraw(canvas);
}


@Override
public boolean onTouchEvent(MotionEvent event) {
    if (isUserInteractionEnabled) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                mPath.moveTo(event.getX(), event.getY());
                break;
            case MotionEvent.ACTION_MOVE:
                mPath.lineTo(event.getX(), event.getY());
                invalidate();
                break;
            case MotionEvent.ACTION_UP:
                break;
        }
    }

    return true;
}

public void moveCursorTo(float x, float y) {
    mPath.moveTo(x, y);
}

public void makeLine(float toX, float toY) {
    mPath.lineTo(toX, toY);
}

public void setUserInteractionEnabled(boolean userInteractionEnabled) {
    isUserInteractionEnabled = userInteractionEnabled;
}
}

And then use it like

drawingCanvas.setUserInteractionEnabled(true) // to enable user interaction
drawingCanvas.setUserInteractionEnabled(true) // to disable user interaction

To Draw programatically

drawingCanvas.moveCursorTo(70f, 70f) // Move the cursor (Define starting point)
drawingCanvas.makeLine(200f, 200f) // End point (To where you need to draw)

NextRow = Application.WorksheetFunction.CountA(Range("A:A")) + 1

I propose an alternative method using seaborn

Working code:

import pandas as pd
import seaborn as sns
data=np.random.rand(10,2)*100
df = pd.DataFrame(data, columns=['A', 'B'])
ax= sns.lineplot(data=df, markers= True)
ax.set(xlabel='xlabel', ylabel='ylabel', title='title')
#changing ylables ticks
y_value=['{:,.2f}'.format(x) + '%' for x in ax.get_yticks()]
ax.set_yticklabels(y_value)

Using environment variable is sometimes more convenient when you do not control the build scripts / process.

For C includes use C_INCLUDE_PATH.

For C++ includes use CPLUS_INCLUDE_PATH.

See this link for other gcc environment variables.

Example usage in MacOS / Linux

# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)

C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg

Example usage in Windows

set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"

pip install asyncpg

# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=

Android Studio 4.0.1

in my case when I press Alt + 6 it shows logcat with no problem but when I click to dismiss it will disappear again and will not be pinned at the bottom so I pressed this little button on the bottom left the screen it worked. hope it will help somebody :)

Most OLD c++ and c functions, when deal with strings, use const char*.
With STL and std::string, string.c_str() is introduced to be able to convert from std::string to const char*.

That means that if you promise not to change the buffer, you'll be able to use read only string contents. PROMISE = const char*

I suggest you to read the Enumeration: Traversing a Collection’s Elements part of the Collections Programming Guide for Cocoa. There is a sample code for your need.

This should solve your problem, you should try to run the following below:

Have you added the google maven endpoint?

Important: The support libraries are now available through Google's Maven repository. You do not need to download the support repository from the SDK Manager. For more information, see Support Library Setup.

Add the endpoint to your build.gradle file:

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com'
        }
    }
}

Which can be replaced by the shortcut google() since Android Gradle v3:

allprojects {
    repositories {
        jcenter()
        google()
    }
}

If you already have any maven url inside repositories, you can add the reference after them, i.e.:

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

I think its up to you. I certainly think the .HasValue approach is more readable, especially with developers not familiar with the ?? syntax.

The other point of a nullable boolean type is that it is tristate, so you may want to do something else when it is just null, and not default to false.

in my case it was just an intermittent issues it seems, didn't work for a few tries, then looked at https://registry.npmjs.org (webpage worked fine), tried again, tried again and then it worked.

To answer the question more generaly how to redirect standard output to a variable ?

do the following :

from io import StringIO
import sys

result = StringIO()
sys.stdout = result
result_string = result.getvalue()

If you need to do that only in some function do the following :

old_stdout = sys.stdout  

# your function containing the previous lines
my_function()

sys.stdout = old_stdout

You can use ListView to render a list of items. But if you don't want to use ListView, you can create a method which returns a list of Widgets (Texts in your case) like below:

var list = ["one", "two", "three", "four"];

    @override
    Widget build(BuildContext context) {
      return new MaterialApp(
          home: new Scaffold(
        appBar: new AppBar(
          title: new Text('List Test'),
        ),
        body: new Center(
          child: new Column( // Or Row or whatever :)
            children: createChildrenTexts(),
          ),
        ),
      ));
    }

     List<Text> createChildrenTexts() {
    /// Method 1
//    List<Text> childrenTexts = List<Text>();
//    for (String name in list) {
//      childrenTexts.add(new Text(name, style: new TextStyle(color: Colors.red),));
//    }
//    return childrenTexts;

    /// Method 2
    return list.map((text) => Text(text, style: TextStyle(color: Colors.blue),)).toList();
  }

I found that you can just do this in Chrome:

  $('.onload-fadein').each(function (k, v) {
    v.onload = function () {
        $(this).animate({opacity: 1}, 2000);
    };
    v.src = v.src;
});

Setting the .src to itself will trigger the onload event.

Make sure you are on the right directory where you have package.json

By adding using System.Timers; to your program you can use this function:

private static void delay(int Time_delay)
{
   int i=0;
  //  ameTir = new System.Timers.Timer();
    _delayTimer = new System.Timers.Timer();
    _delayTimer.Interval = Time_delay;
    _delayTimer.AutoReset = false; //so that it only calls the method once
    _delayTimer.Elapsed += (s, args) => i = 1;
    _delayTimer.Start();
    while (i == 0) { };
}

Delay is a function and can be used like:

delay(5000);

In java 5 new feature added that is Scanner method who gives the chance to read input character by character in java.

for instance; for use Scanner method import java.util.Scanner; after in main method:define

Scanner myScanner = new Scanner(System.in); //for read character

char anything=myScanner.findInLine(".").charAt(0);

you anything store single character, if you want more read more character declare more object like anything1,anything2... more example for your answer please check in your hand(copy/paste)

     import java.util.Scanner;
     class ReverseWord  {

    public static void main(String args[]){
    Scanner myScanner=new Scanner(System.in);
    char c1,c2,c3,c4;

    c1 = myScanner.findInLine(".").charAt(0);
        c2 = myScanner.findInLine(".").charAt(0);
    c3 = myScanner.findInLine(".").charAt(0);
    c4 = myScanner.findInLine(".").charAt(0);

    System.out.print(c4);
    System.out.print(c3);
    System.out.print(c2);
    System.out.print(c1);
    System.out.println();

   }
  }

try this one npm cache clean --force after that run npm cache verify

One way is to use the lattice package and xyplot():

R> DF <- data.frame(x=1:10, y=rnorm(10)+5, 
+>                  z=sample(letters[1:3], 10, replace=TRUE))
R> DF
    x       y z
1   1 3.91191 c
2   2 4.57506 a
3   3 3.16771 b
4   4 5.37539 c
5   5 4.99113 c
6   6 5.41421 a
7   7 6.68071 b
8   8 5.58991 c
9   9 5.03851 a
10 10 4.59293 b
R> with(DF, xyplot(y ~ x, group=z))

By giving explicit grouping information via variable z, you obtain different colors. You can specify colors etc, see the lattice documentation.

Because z here is a factor variable for which we obtain the levels (== numeric indices), you can also do

R> with(DF, plot(x, y, col=z))

but that is less transparent (to me, at least :) then xyplot() et al.

You may want to look into Maven release plugin's release:update-versions goal. It will update the parent's version as well as all the modules under it.

Update: Please note that the above is the release plugin. If you are not releasing, you may want to use versions:set

mvn versions:set -DnewVersion=1.2.3-SNAPSHOT

The Windows API has the functions UrlEscape/UrlUnescape, exported by shlwapi.dll, for this task.

The AngularJS way of calling $http would look like:

$http({
    url: "http://example.appspot.com/rest/app",
    method: "POST",
    data: {"foo":"bar"}
}).then(function successCallback(response) {
        // this callback will be called asynchronously
        // when the response is available
        $scope.data = response.data;
    }, function errorCallback(response) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
        $scope.error = response.statusText;
});

or could be written even simpler using shortcut methods:

$http.post("http://example.appspot.com/rest/app", {"foo":"bar"})
.then(successCallback, errorCallback);

There are number of things to notice:

• AngularJS version is more concise (especially using .post() method)
• AngularJS will take care of converting JS objects into JSON string and setting headers (those are customizable)
• Callback functions are named success and error respectively (also please note parameters of each callback) - Deprecated in angular v1.5
• use then function instead.
• More info of then usage can be found here

The above is just a quick example and some pointers, be sure to check AngularJS documentation for more: http://docs.angularjs.org/api/ng.$http

Put it as a background on your holder e.g.

<div style="background:url(path/to/image/myimage.jpg) center center; width:120px; height:120px;">
&nbsp;
</div>

This will center your image inside a 120x120 div chopping off any excess of the image

State machines can be very complex for a complex problem. They are also subject to unexpected bugs. They can turn into a nightmare if someone runs into a bug or needs to change the logic in the future. They are also difficult to follow and debug without the state diagram. Structured programming is much better (for example you would probably not use a state machine at mainline level). You can use structured programming even in interrupt context (which is where state machines are usually used). See this article "Macros to simulate multi-tasking/blocking code at interrupt level" found at codeproject.com.

QApplication is derived from QCoreApplication and thereby inherits quit() which is a public slot of QCoreApplication, so there is no difference between QApplication::quit() and QCoreApplication::quit().

As we can read in the documentation of QCoreApplication::quit() it "tells the application to exit with return code 0 (success).". If you want to exit because you discovered file corruption then you may not want to exit with return code zero which means success, so you should call QCoreApplication::exit() because you can provide a non-zero returnCode which, by convention, indicates an error.

It is important to note that "if the event loop is not running, this function (QCoreApplication::exit()) does nothing", so in that case you should call exit(EXIT_FAILURE).

You could implement it like this:

@SuppressWarnings("unchecked")
public <T extends Animal> T callFriend(String name) {
    return (T)friends.get(name);
}

(Yes, this is legal code; see Java Generics: Generic type defined as return type only.)

The return type will be inferred from the caller. However, note the @SuppressWarnings annotation: that tells you that this code isn't typesafe. You have to verify it yourself, or you could get ClassCastExceptions at runtime.

Unfortunately, the way you're using it (without assigning the return value to a temporary variable), the only way to make the compiler happy is to call it like this:

jerry.<Dog>callFriend("spike").bark();

While this may be a little nicer than casting, you are probably better off giving the Animal class an abstract talk() method, as David Schmitt said.

try this:

[self dismissViewControllerAnimated:true completion:nil];

In addition to Idriss answer:

CSS

In CSS we write code as depicted bellow, in full length.

body{
 width: 800px;
 color: #ffffff;
}
body content{
 width:750px;
 background:#ffffff;
}

SCSS

In SCSS we can shorten this code using a @mixin so we don’t have to write color and width properties again and again. We can define this through a function, similarly to PHP or other languages.

$color: #ffffff;
$width: 800px;

@mixin body{
 width: $width;
 color: $color;

 content{
  width: $width;
  background:$color;
 }
}

SASS

In SASS however, the whole structure is visually quicker and cleaner than SCSS.

• It is sensitive to white space when you are using copy and paste,

• It seems that it doesn't support inline CSS currently.

  $color: #ffffff
  $width: 800px
  $stack: Helvetica, sans-serif
  
  body
    width: $width
    color: $color
    font: 100% $stack
  
    content
      width: $width
      background:$color
  

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

How about?

<?php
   $queried_post = get_page_by_path('my_slug',OBJECT,'post');
?>

This can occur when Safari is in private mode browsing. While in private browsing, local storage is not available at all.

One solution is to warn the user that the app needs non-private mode to work.

UPDATE: This has been fixed in Safari 11, so the behaviour is now aligned with other browsers.

You can pass a numpy array or matrix as an argument when initializing a sparse matrix. For a CSR matrix, for example, you can do the following.

>>> import numpy as np
>>> from scipy import sparse
>>> A = np.array([[1,2,0],[0,0,3],[1,0,4]])
>>> B = np.matrix([[1,2,0],[0,0,3],[1,0,4]])

>>> A
array([[1, 2, 0],
       [0, 0, 3],
       [1, 0, 4]])

>>> sA = sparse.csr_matrix(A)   # Here's the initialization of the sparse matrix.
>>> sB = sparse.csr_matrix(B)

>>> sA
<3x3 sparse matrix of type '<type 'numpy.int32'>'
        with 5 stored elements in Compressed Sparse Row format>

>>> print sA
  (0, 0)        1
  (0, 1)        2
  (1, 2)        3
  (2, 0)        1
  (2, 2)        4

Look at stat for checking if the directory exists,

And mkdir, to create a directory.

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

struct stat st = {0};

if (stat("/some/directory", &st) == -1) {
    mkdir("/some/directory", 0700);
}

You can see the manual of these functions with the man 2 stat and man 2 mkdir commands.

The question is simply asked wrong. You don't make an alias that takes parameters because alias just adds a second name for something that already exists. The functionality the OP wants is the function command to create a new function. You do not need to alias the function as the function already has a name.

I think you want something like this :

function trash() { mv "$@" ~/.Trash; }

That's it! You can use parameters $1, $2, $3, etc, or just stuff them all with $@

Wait function using timers, no UI locks.

public void wait(int milliseconds)
{
    var timer1 = new System.Windows.Forms.Timer();
    if (milliseconds == 0 || milliseconds < 0) return;

    // Console.WriteLine("start wait timer");
    timer1.Interval = milliseconds;
    timer1.Enabled  = true;
    timer1.Start();

    timer1.Tick += (s, e) =>
    {
        timer1.Enabled = false;
        timer1.Stop();
        // Console.WriteLine("stop wait timer");
    };

    while (timer1.Enabled)
    {
        Application.DoEvents();
    }
}

Usage: just placing this inside your code that needs to wait:

wait(1000); //wait one second

Serializable is a standard Java interface. You simply mark a class Serializable by implementing the interface, and Java will automatically serialize it in certain situations.

Parcelable is an Android specific interface where you implement the serialization yourself. It was created to be far more efficient that Serializable, and to get around some problems with the default Java serialization scheme.

I believe that Binder and AIDL work with Parcelable objects.

However, you can use Serializable objects in Intents.

Here is a quick fix:

All the pros will probably hate me for this answer. But I got the same error on a server: Fatal error: Uncaught Error: Call to undefined function mysql_connect() that was using PHP 7. Did not have time to rewrite all the mysql code so a quick, temporary fix if anyone needs it is in CPANEL to look for PHP Configuration and change the version for that account to something like PHP 5.4 instead of PHP 7. Then the code worked fine without the above error.

It's go to newline then add spaces to start second line at end of first line

Output

Hello
     Goodbye

please note, if you use $filter like this:

$scope.failedSubjects = $filter('filter')($scope.results.subjects, {'grade':'C'});

and you happened to have another grade for, Oh I don't know, CC or AC or C+ or CCC it pulls them in to. you need to append a requirement for an exact match:

$scope.failedSubjects = $filter('filter')($scope.results.subjects, {'grade':'C'}, true);

This really killed me when I was pulling in some commission details like this:

var obj = this.$filter('filter')(this.CommissionTypes, { commission_type_id: 6}))[0];

only get called in for a bug because it was pulling in the commission ID 56 rather than 6.

Adding the true forces an exact match.

var obj = this.$filter('filter')(this.CommissionTypes, { commission_type_id: 6}, true))[0];

Yet still, I prefer this (I use typescript, hence the "Let" and =>):

let obj = this.$filter('filter')(this.CommissionTypes, (item) =>{ 
             return item.commission_type_id === 6;
           })[0];

I do that because, at some point down the road, I might want to get some more info from that filtered data, etc... having the function right in there kind of leaves the hood open.

 <?php
    $hostname_conn = "localhost";
    $database_conn = "user_id";
    $username_conn = "root";
    $password_conn = "";
     $conn = mysql_pconnect($hostname_conn, $username_conn,   $password_conn) or trigger_error(mysql_error(),E_USER_ERROR); 
   mysql_select_db($database_conn,$conn);
   // run an endless loop      
    while(1) {       
    $randomNumber = rand(1, 999999);// generate unique random number               
    $query = "SELECT * FROM tbl_rand WHERE the_number='".mysql_real_escape_string ($randomNumber)."'";  // check if it exists in database   
    $res =mysql_query($query,$conn);       
    $rowCount = mysql_num_rows($res);
     // if not found in the db (it is unique), then insert the unique number into data_base and break out of the loop
    if($rowCount < 1) {
    $con = mysql_connect ("localhost","root");      
    mysql_select_db("user_id", $con);       
    $sql = "insert into tbl_rand(the_number) values('".$randomNumber."')";      
    mysql_query ($sql,$con);        
    mysql_close ($con);
    break;
    }   
}
  echo "inserted unique number into Data_base. use it as ID";
   ?>

You might try a lazy unmount:

umount -l

Take a look at the Java standard API doc. Right next to LinkedHashMap, there is a LinkedHashSet. But note that the order in those is the insertion order, not the natural order of the elements. And you can only iterate in that order, not do random access (except by counting iteration steps).

There is also an interface SortedSet implemented by TreeSet and ConcurrentSkipListSet. Both allow iteration in the natural order of their elements or a Comparator, but not random access or insertion order.

For a data structure that has both efficient access by index and can efficiently implement the set criterium, you'd need a skip list, but there is no implementation with that functionality in the Java Standard API, though I am certain it's easy to find one on the internet.

I just created this and it looks easier. You get these 2 functions:

=GetColorIndex(E5)  <- returns color number for the cell

from (cell)

=CountColorIndexInRange(C7:C24,14) <- returns count of cells C7:C24 with color 14

from (range of cells, color number you want to count)

example shows percent of cells with color 14

=ROUND(CountColorIndexInRange(C7:C24,14)/18, 4 )

Create these 2 VBA functions in a Module (hit Alt-F11)

open + folders. double-click on Module1

Just paste this text below in, then close the module window (it must save it then):

Function GetColorIndex(Cell As Range)
  GetColorIndex = Cell.Interior.ColorIndex
End Function

Function CountColorIndexInRange(Rng As Range, TestColor As Long)
  Dim cnt
  Dim cl As Range
  cnt = 0

  For Each cl In Rng
    If GetColorIndex(cl) = TestColor Then
      Rem Debug.Print ">" & TestColor & "<"
      cnt = cnt + 1
    End If
  Next

  CountColorIndexInRange = cnt

End Function

I realize this is an old post but I find myself coming back to this thread a lot as it is one of the top search results when searching for this topic. However, I always leave more confused then when I came due to the conflicting information. Ultimately I always have to perform my own tests to figure it out. So this time I will post my findings.

TL;DR Most people will want to use Exit to terminate a running scripts. However, if your script is merely declaring functions to later be used in a shell, then you will want to use Return in the definitions of said functions.

Exit vs Return vs Break

• Exit: This will "exit" the currently running context. If you call this command from a script it will exit the script. If you call this command from the shell it will exit the shell.

  If a function calls the Exit command it will exit what ever context it is running in. So if that function is only called from within a running script it will exit that script. However, if your script merely declares the function so that it can be used from the current shell and you run that function from the shell, it will exit the shell because the shell is the context in which the function contianing the Exit command is running.

  Note: By default if you right click on a script to run it in PowerShell, once the script is done running, PowerShell will close automatically. This has nothing to do with the Exit command or anything else in your script. It is just a default PowerShell behavior for scripts being ran using this specific method of running a script. The same is true for batch files and the Command Line window.

• Return: This will return to the previous call point. If you call this command from a script (outside any functions) it will return to the shell. If you call this command from the shell it will return to the shell (which is the previous call point for a single command ran from the shell). If you call this command from a function it will return to where ever the function was called from.

  Execution of any commands after the call point that it is returned to will continue from that point. If a script is called from the shell and it contains the Return command outside any functions then when it returns to the shell there are no more commands to run thus making a Return used in this way essentially the same as Exit.

• Break: This will break out of loops and switch cases. If you call this command while not in a loop or switch case it will break out of the script. If you call Break inside a loop that is nested inside a loop it will only break out of the loop it was called in.

  There is also an interesting feature of Break where you can prefix a loop with a label and then you can break out of that labeled loop even if the Break command is called within several nested groups within that labeled loop.

  While ($true) {
      # Code here will run
  
      :myLabel While ($true) {
          # Code here will run
  
          While ($true) {
              # Code here will run
  
              While ($true) {
                  # Code here will run
                  Break myLabel
                  # Code here will not run
              }
  
              # Code here will not run
          }
  
          # Code here will not run
      }
  
      # Code here will run
  }
  

This is a new security feature of iOS 9. Watch WWDC 2015 Session 703 for more information.

Any app built with SDK 9 needs to provide a LSApplicationQueriesSchemes entry in its plist file, declaring which schemes it attempts to query.

<key>LSApplicationQueriesSchemes</key>
<array>
 <string>urlscheme</string>
 <string>urlscheme2</string>
 <string>urlscheme3</string>
 <string>urlscheme4</string>
</array> 

You can't change the color of the line (you can't specify different foreground colors for the same element, and the text and its decoration form a single element). However there are some tricks:

a:link, a:visited {text-decoration: none; color: red; border-bottom: 1px solid #006699; }
a:hover, a:active {text-decoration: none; color: red; border-bottom: 1px solid #1177FF; }

Also you can make some cool effects this way:

a:link {text-decoration: none; color: red; border-bottom: 1px dashed #006699; }

Hope it helps.

As others mentioned, it's only possible via reflection in certain circumstances.

If you really need the type, this is the usual (type-safe) workaround pattern:

public class GenericClass<T> {

     private final Class<T> type;

     public GenericClass(Class<T> type) {
          this.type = type;
     }

     public Class<T> getMyType() {
         return this.type;
     }
}

You can take update / pull on git branch you can use below command

git pull origin <branch-name>

The above command will take an update/pull from giving branch name

If you want to take pull from another branch, you need to go to that branch.

git checkout master

Than

git pull origin development

Hope that will work for you

A simple regex that will match, but I wouldn't recommend for validation of any sort is this:

([A-Fa-f0-9]{1,4}::?){1,7}[A-Fa-f0-9]{1,4}

Note this matches compression anywhere in the address, though it won't match the loopback address ::1. I find this a reasonable compromise in order to keep the regex simple.

I successfully use this in iTerm2 smart selection rules to quad-click IPv6 addresses.

Import mplot3d whole to use "projection = '3d'".

Insert the command below in top of your script. It should run fine.

from mpl_toolkits import mplot3d

byte[] bytes = File.ReadAllBytes(filename) 

or ...

var bytes = File.ReadAllBytes(filename) 

In some cases related with responsive layout $(document).height() can return wrong data that displays view port height only. For example when some div#wrapper has height:100%, that #wrapper can be stretched by some block inside it. But it's height still will be like viewport height. In such situation you might use

$('#wrapper').get(0).scrollHeight

That represents actual size of wrapper.

Try this function : mltiple queries and multiple values insertion.

function employmentStatus($Status) {
$pdo = PDO2::getInstance();

$sql_parts = array(); 
for($i=0; $i<count($Status); $i++){
    $sql_parts[] = "(:userID, :val$i)";
}

$requete = $pdo->dbh->prepare("DELETE FROM employment_status WHERE userid = :userID; INSERT INTO employment_status (userid, status) VALUES ".implode(",", $sql_parts));
$requete->bindParam(":userID", $_SESSION['userID'],PDO::PARAM_INT);
for($i=0; $i<count($Status); $i++){
    $requete->bindParam(":val$i", $Status[$i],PDO::PARAM_STR);
}
if ($requete->execute()) {
    return true;
}
return $requete->errorInfo();
}

One can also use the following class while using bootstrap modal class (v 3.3.7) ... help-inline and help-block did not work in modal.

<span class="error text-danger">Some Errors related to something</span>

Output looks like something below:

var today = new Date().toISOString().split('T')[0];
$("#datePicker").val(today);

Above code will work.

This is expected. Refer to Javadocs for split.

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

This SQL query gives output similar to \dx:

SELECT e.extname AS "Name", e.extversion AS "Version", n.nspname AS "Schema", c.description AS "Description" 
FROM pg_catalog.pg_extension e 
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = e.extnamespace 
LEFT JOIN pg_catalog.pg_description c ON c.objoid = e.oid AND c.classoid = 'pg_catalog.pg_extension'::pg_catalog.regclass 
ORDER BY 1;

Error in df %<>% mutate_if(is.character, as.numeric) : 
  could not find function "%<>%"

I did some quick research and found this note in Hadley's "The tidyverse style guide".

The magrittr package provides the %<>% operator as a shortcut for modifying an object in place. Avoid this operator.

# Good x <- x %>%
           abs() %>%    
           sort()

# Bad x %<>%   
          abs() %>%
          sort()

Solution

Based on that style guide:

df_clean <- df %>% mutate_if(is.character, as.numeric)

Working example

> df_clean <- df %>% mutate_if(is.character, as.numeric)

I need to decrypt a password. The password is crypted with password_hash function.

$password = 'examplepassword';
$crypted = password_hash($password, PASSWORD_DEFAULT);

Its not clear to me if you need password_verify, or you are trying to gain unauthorized access to the application or database. Other have talked about password_verify, so here's how you could gain unauthorized access. Its what bad guys often do when they try to gain access to a system.

First, create a list of plain text passwords. A plain text list can be found in a number of places due to the massive data breaches from companies like Adobe. Sort the list and then take the top 10,000 or 100,000 or so.

Second, create a list of digested passwords. Simply encrypt or hash the password. Based on your code above, it does not look like a salt is being used (or its a fixed salt). This makes the attack very easy.

Third, for each digested password in the list, perform a select in an attempt to find a user who is using the password:

$sql_script = 'select * from USERS where password="'.$digested_password.'"'

Fourth, profit.

So, rather than picking a user and trying to reverse their password, the bad guy picks a common password and tries to find a user who is using it. Odds are on the bad guy's side...

Because the bad guy does these things, it would behove you to not let users choose common passwords. In this case, take a look at ProCheck, EnFilter or Hyppocrates (et al). They are filtering libraries that reject bad passwords. ProCheck achieves very high compression, and can digest multi-million word password lists into a 30KB data file.

Starting with Sql Server 2012: string concatenation function CONCAT converts to string implicitly. Therefore, another option is

SELECT Id AS 'PatientId',
       CONCAT(ParentId,'') AS 'ParentId'
FROM Patients

CONCAT converts null values to empty strings.

Some will consider this hacky, because it merely exploits a side effect of a function while the function itself isn't required for the task in hand.

The following solution worked for me...

I tried everything mentioned above but still didn't get my app running. I have react-native app running on latest version of gradle 4+ and android studio.

I had the issue where if i run react-native run-android it was failing with issue saying its not able to find MainApplication class...i.e ClassNotFoundException

I was able to resolve the issue when I updated my gradle.properties to use the compiler D8.

I added:

android.enableD8=true

to my gradle.properties

There are JDK versions available from the base CentOS repositories. Depending on your version of CentOS, and the JDK you want to install, the following as root should give you what you want:

OpenJDK Runtime Environment (Java SE 6)

yum install java-1.6.0-openjdk

OpenJDK Runtime Environment (Java SE 7)

yum install java-1.7.0-openjdk

OpenJDK Development Environment (Java SE 7)

yum install java-1.7.0-openjdk-devel

OpenJDK Development Environment (Java SE 6)

yum install java-1.6.0-openjdk-devel

Update for Java 8

In CentOS 6.6 or later, Java 8 is available. Similar to 6 and 7 above, the packages are as follows:

OpenJDK Runtime Environment (Java SE 8)

yum install java-1.8.0-openjdk

OpenJDK Development Environment (Java SE 8)

yum install java-1.8.0-openjdk-devel

There's also a 'headless' JRE package that is the same as the above JRE, except it doesn't contain audio/video support. This can be used for a slightly more minimal installation:

OpenJDK Runtime Environment - Headless (Java SE 8)

yum install java-1.8.0-openjdk-headless

The following codes should give you the fastest speed for big data as long as you have many cores on your computer:

if (!require("pacman")) install.packages("pacman")
pacman::p_load(doParallel, data.table, stringr)

# get the file name
dir() %>% str_subset("\\.csv$") -> fn

# use parallel setting
(cl <- detectCores() %>%
  makeCluster()) %>%
  registerDoParallel()

# read and bind all files together
system.time({
  big_df <- foreach(
    i = fn,
    .packages = "data.table"
  ) %dopar%
    {
      fread(i, colClasses = "character")
    } %>%
    rbindlist(fill = TRUE)
})

# end of parallel work
stopImplicitCluster(cl)

Updated in 2020/04/16: As I find a new package available for parallel computation, an alternative solution is provided using the following codes.

if (!require("pacman")) install.packages("pacman")
pacman::p_load(future.apply, data.table, stringr)

# get the file name
dir() %>% str_subset("\\.csv$") -> fn

plan(multiprocess)

future_lapply(fn,fread,colClasses = "character") %>% 
  rbindlist(fill = TRUE) -> res

# res is the merged data.table

My suggestions :

• Keep the program modular. Keep the Calculate class in a separate Calculate.java file and create a new class that calls the main method. This would make the code readable.

• For setting the values in the number, use constructors. Do not use like the methods you have used above like :

  public void setNumber(double fnum, double snum){ this.fn = fnum; this.sn = snum; }

  Constructors exists to initialize the objects.This is their job and they are pretty good at it.

• Getters for members of Calculate class seem in place. But setters are not. Getters and setters serves as one important block in the bridge of efficient programming with java. Put setters for fnum and snum as well

• In the main class, create a Calculate object using the new operator and the constructor in place.

• Call the getAnswer() method with the created Calculate object.

Rest of the code looks fine to me. Be modular. You could read your program in a much better way.

Here is my modular piece of code. Two files : Main.java & Calculate.java

Calculate.java

public class Calculate {


private double fn;
private double sn;
private char op;

    public double getFn() {
        return fn;
    }

    public void setFn(double fn) {
        this.fn = fn;
    }

    public double getSn() {
        return sn;
    }

    public void setSn(double sn) {
        this.sn = sn;
    }

    public char getOp() {
        return op;
    }

    public void setOp(char op) {
        this.op = op;
    }



    public Calculate(double fn, double sn, char op) {
        this.fn = fn;
        this.sn = sn;
        this.op = op;
    }


public void getAnswer(){
    double ans;
    switch (getOp()){
        case '+': 
            ans = add(getFn(), getSn());
            ansOutput(ans);
            break;
        case '-': 
            ans = sub (getFn(), getSn());
            ansOutput(ans);
            break;
        case '*': 
            ans = mul (getFn(), getSn());
            ansOutput(ans);
            break;
        case '/': 
            ans = div (getFn(), getSn());
            ansOutput(ans);
            break;
        default:
            System.out.println("--------------------------");
            System.out.println("Invalid choice of operator");
            System.out.println("--------------------------");
        }
    }
    public static double add(double x,double y){
        return x + y;
    }
    public static double sub(double x, double y){
        return x - y;
    }
    public static double mul(double x, double y){
        return x * y;
    }
    public static double div(double x, double y){
        return x / y;
    }

    public static void ansOutput(double x){
        System.out.println("----------- -------");
        System.out.printf("the answer is %.2f\n", x);
        System.out.println("-------------------");
    }
}

Main.java

public class Main {
    public static void main(String args[])
    {
        Calculate obj = new Calculate(1,2,'+');
        obj.getAnswer();
    }
}

Modern javascript controls as well as JSON requests can be handled much easily using MVC. There we can use a lot of other mechanisms to post data from one action to another action. That's why we prefer MVC over web forms. Also we can build light weight pages.

I made some fixes for @Pinhassi solution. It handles some cases:

1.you can move cursor anywhere

2.minus sign handling

3.digitsbefore = 2 and digitsafter = 4 and you enter 12.4545. Then if you want to remove ".", it will not allow.

public class DecimalDigitsInputFilter implements InputFilter {
    private int mDigitsBeforeZero;
    private int mDigitsAfterZero;
    private Pattern mPattern;

    private static final int DIGITS_BEFORE_ZERO_DEFAULT = 100;
    private static final int DIGITS_AFTER_ZERO_DEFAULT = 100;

    public DecimalDigitsInputFilter(Integer digitsBeforeZero, Integer digitsAfterZero) {
    this.mDigitsBeforeZero = (digitsBeforeZero != null ? digitsBeforeZero : DIGITS_BEFORE_ZERO_DEFAULT);
    this.mDigitsAfterZero = (digitsAfterZero != null ? digitsAfterZero : DIGITS_AFTER_ZERO_DEFAULT);
    mPattern = Pattern.compile("-?[0-9]{0," + (mDigitsBeforeZero) + "}+((\\.[0-9]{0," + (mDigitsAfterZero)
        + "})?)||(\\.)?");
    }

    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    String replacement = source.subSequence(start, end).toString();
    String newVal = dest.subSequence(0, dstart).toString() + replacement
        + dest.subSequence(dend, dest.length()).toString();
    Matcher matcher = mPattern.matcher(newVal);
    if (matcher.matches())
        return null;

    if (TextUtils.isEmpty(source))
        return dest.subSequence(dstart, dend);
    else
        return "";
    }
}

You must change the cmake C/CXX default FLAGS .

According to CMAKE_BUILD_TYPE={DEBUG/MINSIZEREL/RELWITHDEBINFO/RELEASE} put in the main CMakeLists.txt one of :

For C

set(CMAKE_C_FLAGS_DEBUG "put your flags")
set(CMAKE_C_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_C_FLAGS_RELEASE "put your flags")

For C++

set(CMAKE_CXX_FLAGS_DEBUG "put your flags")
set(CMAKE_CXX_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_CXX_FLAGS_RELEASE "put your flags")

This will override the values defined in CMakeCache.txt

You can use the strtok() function to split a string (and specify the delimiter to use). Note that strtok() will modify the string passed into it. If the original string is required elsewhere make a copy of it and pass the copy to strtok().

EDIT:

Example (note it does not handle consecutive delimiters, "JAN,,,FEB,MAR" for example):

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

char** str_split(char* a_str, const char a_delim)
{
    char** result    = 0;
    size_t count     = 0;
    char* tmp        = a_str;
    char* last_comma = 0;
    char delim[2];
    delim[0] = a_delim;
    delim[1] = 0;

    /* Count how many elements will be extracted. */
    while (*tmp)
    {
        if (a_delim == *tmp)
        {
            count++;
            last_comma = tmp;
        }
        tmp++;
    }

    /* Add space for trailing token. */
    count += last_comma < (a_str + strlen(a_str) - 1);

    /* Add space for terminating null string so caller
       knows where the list of returned strings ends. */
    count++;

    result = malloc(sizeof(char*) * count);

    if (result)
    {
        size_t idx  = 0;
        char* token = strtok(a_str, delim);

        while (token)
        {
            assert(idx < count);
            *(result + idx++) = strdup(token);
            token = strtok(0, delim);
        }
        assert(idx == count - 1);
        *(result + idx) = 0;
    }

    return result;
}

int main()
{
    char months[] = "JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC";
    char** tokens;

    printf("months=[%s]\n\n", months);

    tokens = str_split(months, ',');

    if (tokens)
    {
        int i;
        for (i = 0; *(tokens + i); i++)
        {
            printf("month=[%s]\n", *(tokens + i));
            free(*(tokens + i));
        }
        printf("\n");
        free(tokens);
    }

    return 0;
}

Output:

$ ./main.exe
months=[JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC]

month=[JAN]
month=[FEB]
month=[MAR]
month=[APR]
month=[MAY]
month=[JUN]
month=[JUL]
month=[AUG]
month=[SEP]
month=[OCT]
month=[NOV]
month=[DEC]

You can initialise the whole result list in the top level call to mergesort:

result = [0]*len(x)   # replace 0 with a suitable default element if necessary. 
                      # or just copy x (result = x[:])

Then for the recursive calls you can use a helper function to which you pass not sublists, but indices into x. And the bottom level calls read their values from x and write into result directly.

That way you can avoid all that poping and appending which should improve performance.

The stack already exists, so you can assume that when writing your code. The stack contains the return addresses of the functions, the local variables and the variables which are passed between functions. There are also stack registers such as BP, SP (Stack Pointer) built-in that you can use, hence the built-in commands you have mentioned. If the stack wasn't already implemented, functions couldn't run, and code flow couldn't work.

There is a really nice, easy to use, lightweight (uses native browser events for detection) plugin for both basic JavaScript and for jQuery that was released this year. It performs perfectly:

https://github.com/sdecima/javascript-detect-element-resize

Surprised to see no one mentioned more capable, interactive and easier to use alternatives.

A) You can use plotly:

1. Just two lines and you get:

2. interactivity,

3. smooth scale,

4. colors based on whole dataframe instead of individual columns,

5. column names & row indices on axes,

6. zooming in,

7. panning,

8. built-in one-click ability to save it as a PNG format,

9. auto-scaling,

10. comparison on hovering,

11. bubbles showing values so heatmap still looks good and you can see values wherever you want:

import plotly.express as px
fig = px.imshow(df.corr())
fig.show()

B) You can also use Bokeh:

All the same functionality with a tad much hassle. But still worth it if you do not want to opt-in for plotly and still want all these things:

from bokeh.plotting import figure, show, output_notebook
from bokeh.models import ColumnDataSource, LinearColorMapper
from bokeh.transform import transform
output_notebook()
colors = ['#d7191c', '#fdae61', '#ffffbf', '#a6d96a', '#1a9641']
TOOLS = "hover,save,pan,box_zoom,reset,wheel_zoom"
data = df.corr().stack().rename("value").reset_index()
p = figure(x_range=list(df.columns), y_range=list(df.index), tools=TOOLS, toolbar_location='below',
           tooltips=[('Row, Column', '@level_0 x @level_1'), ('value', '@value')], height = 500, width = 500)

p.rect(x="level_1", y="level_0", width=1, height=1,
       source=data,
       fill_color={'field': 'value', 'transform': LinearColorMapper(palette=colors, low=data.value.min(), high=data.value.max())},
       line_color=None)
color_bar = ColorBar(color_mapper=LinearColorMapper(palette=colors, low=data.value.min(), high=data.value.max()), major_label_text_font_size="7px",
                     ticker=BasicTicker(desired_num_ticks=len(colors)),
                     formatter=PrintfTickFormatter(format="%f"),
                     label_standoff=6, border_line_color=None, location=(0, 0))
p.add_layout(color_bar, 'right')

show(p)

Fragmentation. Char reserves space and VarChar does not. Page split can be required to accommodate update to varchar.

To improve James' excellent answer:

It's better to put BINARY in front of the constant instead:

SELECT * FROM `table` WHERE `column` = BINARY 'value'

Putting BINARY in front of column will prevent the use of any index on that column.

I would consider this more of an old-school C style; it is not really good practice in JavaScript so you should avoid it.

In ascending order you can use:

sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]))

or in descending order you can use:

sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]),reverse=True)

I had to drop the extra quoting using msysGit on windows 7, not sure why.

git config --global merge.tool p4merge
git config --global mergetool.p4merge.cmd 'p4merge $BASE $LOCAL $REMOTE $MERGED'

HashMap<String, String> hashMap = new HashMap<>();
String[] stringValues= new String[hashMap.values().size()];
hashMap.values().toArray(stringValues);

skipUntil() with last()

skipUntil : ignore emitted items until another observable has emitted

last: emit last value from a sequence (i.e. wait until it completes then emit)

Note that anything emitted from the observable passed to skipUntil will cancel the skipping, which is why we need to add last() - to wait for the stream to complete.

main$.skipUntil(sequence2$.pipe(last()))

Official: https://rxjs-dev.firebaseapp.com/api/operators/skipUntil

Possible issue: Note that last() by itself will error if nothing is emitted. The last() operator does have a default parameter but only when used in conjunction with a predicate. I think if this situation is a problem for you (if sequence2$ may complete without emitting) then one of these should work (currently untested):

main$.skipUntil(sequence2$.pipe(defaultIfEmpty(undefined), last()))
main$.skipUntil(sequence2$.pipe(last(), catchError(() => of(undefined))

Note that undefined is a valid item to be emitted, but could actually be any value. Also note that this is the pipe attached to sequence2$ and not the main$ pipe.

df = df.merge(same.drop_duplicates(), on=['col1','col2'],

using System.Net;
using System.Net.Mail;

using(SmtpClient smtpClient = new SmtpClient())
{
    var basicCredential = new NetworkCredential("username", "password"); 
    using(MailMessage message = new MailMessage())
    {
        MailAddress fromAddress = new MailAddress("[email protected]"); 

        smtpClient.Host = "mail.mydomain.com";
        smtpClient.UseDefaultCredentials = false;
        smtpClient.Credentials = basicCredential;

        message.From = fromAddress;
        message.Subject = "your subject";
        // Set IsBodyHtml to true means you can send HTML email.
        message.IsBodyHtml = true;
        message.Body = "<h1>your message body</h1>";
        message.To.Add("[email protected]"); 

        try
        {
            smtpClient.Send(message);
        }
        catch(Exception ex)
        {
            //Error, could not send the message
            Response.Write(ex.Message);
        }
    }
}

You may use the above code.

CDATA is a better general solution.

There are many methods :

1. Center horizontal and vertical align of an element with fixed measure

CSS

 <div style="width:200px;height:100px;position:absolute;left:50%;top:50%;
margin-left:-100px;margin-top:-50px;">
<!–content–>
</div> 

2 . Center horizontally and vertically a single line of text

CSS

<div style="width:400px;height:200px;text-align:center;line-height:200px;">
<!–content–>
</div>  

3 . Center horizontal and vertical align of an element with no specific measure

CSS

<div style="display:table;height:300px;text-align:center;">
<div style="display:table-cell;vertical-align:middle;">
<!–content–>
</div>
</div>  

This happened to me while trying to copy over the PSPDFKIT demo library into my project. I followed all the instructions in the site + all the suggestions on this page.. for some reason it kept on giving the above error, the problem was that if i grepped the message in the error method.. it only appeared in the binary (obviously I have no access to the source code b/c I have to pay for it).

I noticed this in the instruction page though:

So I went to the guts of that config file and found this:

OTHER_LDFLAGS=$(inherited) -ObjC -fobjc-arc -lz -framework CoreText -framework CoreMedia -framework MediaPlayer -framework AVFoundation -framework ImageIO -framework MediaPlayer -framework MessageUI -framework CoreGraphics -framework Foundation -framework QuartzCore -framework AVFoundation -framework CFNetwork -framework MobileCoreServices -framework SystemConfiguration -weak_framework UIKit

Then I went to the sample project provided by the author of the said library.. and noticed that the previous flags where copied verbatim to the other linker flags in my build settings.. however in my project.. they were not!.. So i simply copied and pasted them into my project's build settings other linker flags and everything worked!

take away point: if you are relying on some .xcconfig file on your setup, double check with a sample code source or something and make sure that it has actually been applied.. it wasn't applied properly in my case

This looks like the kind of error that Maven generates when you don't have the compiler plugin configured correctly. Here's an example of a Java 8 compiler config.

And see dtoa_base.c for a demonstration of how to convert a double value to string form.

Furthermore, check out section 1.2.1.1.4.2 - Floating-Point Type Memory Layout of the C/CPP Reference Book, it explains super well and in simple terms the memory representation/layout of all the floating-point types and how to decode them (w/ illustrations) following the actually IEEE 754 Floating-Point specification.

It also has links to really really good ressources that explain even deeper.

Internet E-mail address format (RFC 822)

(,)comma separated sequence of addresses

javax.mail - 1.4.7 parse( String[] ) is not allowed. So we have to give comma separated sequence of addresses into InternetAddress objects. Addresses must follow RFC822 syntax.

String toAddress = "[email protected],[email protected]";
InternetAddress.parse( toAddress );

(;) semi-colon separated sequence of addresses « If group of address list is provided with delimeter as ";" then convert to String array using split method to use the following function.

String[] addressList = { "[email protected]", "[email protected]" };

String toGroup = "[email protected];[email protected]";
String[] addressList2 = toGroup.split(";");

setRecipients(message, addressList);

public static void setRecipients(Message message, Object addresslist) throws AddressException, MessagingException {
    if ( addresslist instanceof String ) { // CharSequence
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse( (String) addresslist  ));
    } else if ( addresslist instanceof String[] ) { // String[] « Array with collection of Strings/
        String[] toAddressList = (String[]) addresslist;
        InternetAddress[] mailAddress_TO = new InternetAddress[ toAddressList.length ];
        for (int i = 0; i < toAddressList.length; i++) {
            mailAddress_TO[i] = new InternetAddress( toAddressList[i] );
        }
        message.setRecipients(Message.RecipientType.TO, mailAddress_TO);
    }
}

Full Example:

public static Properties getMailProperties( boolean addExteraProps ) {
    Properties props = new Properties();
    props.put("mail.transport.protocol", MAIL_TRNSPORT_PROTOCOL);
    props.put("mail.smtp.host", MAIL_SERVER_NAME);
    props.put("mail.smtp.port", MAIL_PORT);

    // Sending Email to the GMail SMTP server requires authentication and SSL.
    props.put("mail.smtp.auth", true);
    if( ENCRYPTION_METHOD.equals("STARTTLS") ) {
        props.put("mail.smtp.starttls.enable", true);
        props.put("mail.smtp.socketFactory.port", SMTP_STARTTLS_PORT); // 587
    } else {
        props.put("mail.smtps.ssl.enable", true);
        props.put("mail.smtp.socketFactory.port", SMTP_SSL_PORT); // 465
    }
    props.put("mail.smtp.socketFactory", SOCKETFACTORY_CLASS);
    return props;
}

public static boolean sendMail(String subject, String contentType, String msg, Object recipients) throws Exception {

    Properties props = getMailProperties( false );
    Session mailSession = Session.getInstance(props, null);
    mailSession.setDebug(true);

    Message message = new MimeMessage( mailSession );
    message.setFrom( new InternetAddress( USER_NAME ) );

    setRecipients(message, recipients);

    message.setSubject( subject );

    String htmlData = "<h1>This is actual message embedded in HTML tags</h1>";
    message.setContent( htmlData, "text/html");

    Transport transport = mailSession.getTransport( MAIL_TRNSPORT_PROTOCOL );
    transport.connect(MAIL_SERVER_NAME, Integer.valueOf(MAIL_PORT), USER_NAME, PASSWORD);
    message.saveChanges(); // don't forget this

    transport.sendMessage(message, message.getAllRecipients());
    transport.close();
}

Using Appache SimpleEmail - commons-email-1.3.1

Example: email.addTo( addressList );

public static void sendSimpleMail() throws Exception {
    Email email = new SimpleEmail();
    email.setSmtpPort(587);

    DefaultAuthenticator defaultAuthenticator = new DefaultAuthenticator( USER_NAME, PASSWORD );

    email.setAuthenticator( defaultAuthenticator );
    email.setDebug(false);
    email.setHostName( MAIL_SERVER_NAME );
    email.setFrom( USER_NAME );
    email.setSubject("Hi");
    email.setMsg("This is a test mail ... :-)");

    //email.addTo( "[email protected]", "Yash" );
    String[] toAddressList = { "[email protected]", "[email protected]" }
    email.addTo( addressList );

    email.setTLS(true);
    email.setStartTLSEnabled( true );
    email.send();
    System.out.println("Mail sent!");
}

I am using the following

        ....
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.0.2</version>
            <configuration>
                <finalName>${project.groupId}/${project.artifactId}-${baseVersion}.${monthlyVersion}.${instanceVersion}</finalName>
            </configuration>
        </plugin>
        ....

This way you can define each value individually or pragmatically from Jenkins of some other system.

mvn package -DbaseVersion=1 -monthlyVersion=2 -instanceVersion=3

This will place a folder target\{group.id}\projectName-1.2.3.jar

A better way to save time might be

        ....
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.0.2</version>
            <configuration>
                <finalName>${project.groupId}/${project.artifactId}-${baseVersion}</finalName>
            </configuration>
        </plugin>
        ....

Like the same except I use on variable.

  mvn package -DbaseVersion=0.3.4

This will place a folder target\{group.id}\projectName-1.2.3.jar

you can also use outputDirectory inside of configuration to specify a location you may want the package to be located.

Select the range of cells, type in the value and press Ctrl + Enter.

This, of course, is true if you want to do it manually.

There are two best contenders:

1. Create a 1×1 image data, set the color, and putImageData at the location:

   var id = myContext.createImageData(1,1); // only do this once per page
   var d  = id.data;                        // only do this once per page
   d[0]   = r;
   d[1]   = g;
   d[2]   = b;
   d[3]   = a;
   myContext.putImageData( id, x, y );     
   

2. Use fillRect() to draw a pixel (there should be no aliasing issues):

   ctx.fillStyle = "rgba("+r+","+g+","+b+","+(a/255)+")";
   ctx.fillRect( x, y, 1, 1 );
   

You can test the speed of these here: http://jsperf.com/setting-canvas-pixel/9 or here https://www.measurethat.net/Benchmarks/Show/1664/1

I recommend testing against browsers you care about for maximum speed. As of July 2017, fillRect() is 5-6× faster on Firefox v54 and Chrome v59 (Win7x64).

Other, sillier alternatives are:

• using getImageData()/putImageData() on the entire canvas; this is about 100× slower than other options.

• creating a custom image using a data url and using drawImage() to show it:

  var img = new Image;
  img.src = "data:image/png;base64," + myPNGEncoder(r,g,b,a);
  // Writing the PNGEncoder is left as an exercise for the reader
  

• creating another img or canvas filled with all the pixels you want and use drawImage() to blit just the pixel you want across. This would probably be very fast, but has the limitation that you need to pre-calculate the pixels you need.

Note that my tests do not attempt to save and restore the canvas context fillStyle; this would slow down the fillRect() performance. Also note that I am not starting with a clean slate or testing the exact same set of pixels for each test.

Enclosed in {} represents an object; enclosed in [] represents an array, there can be multiple objects in the array
example object :

{
    "brand": "bwm", 
    "price": 30000
}


{
    "brand": "benz", 
    "price": 50000
}

example array:

[
    {
        "brand": "bwm", 
        "price": 30000
    }, 
    {
        "brand": "benz", 
        "price": 50000
    }
]

In order to use JSON more beautifully, you can go here JSON Viewer do format

int is the C# language's shortcut for System.Int32

Whilst this does mean that Microsoft could change this mapping, a post on FogCreek's discussions stated [source]

"On the 64 bit issue -- Microsoft is indeed working on a 64-bit version of the .NET Framework but I'm pretty sure int will NOT map to 64 bit on that system.

Reasons:

1. The C# ECMA standard specifically says that int is 32 bit and long is 64 bit.

2. Microsoft introduced additional properties & methods in Framework version 1.1 that return long values instead of int values, such as Array.GetLongLength in addition to Array.GetLength.

So I think it's safe to say that all built-in C# types will keep their current mapping."

Steps (in VS Code 1.29.x):

1. Add your JDK's /bin folder to the PATH environmental variable. You can do this under System settings > Environmental variables, or via CLI:

   set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
   

2. Close and reopen your CLI window

A dictionary is not indexed, but it is in some way, ordered. The following would give you the first existing key:

Building on Jared's answer, I had to enable and implement the action bar back button behavior in several activities and created this helper class to reduce code duplication.

public final class ActionBarHelper {
    public static void enableBackButton(AppCompatActivity context) {
        if(context == null) return;

        ActionBar actionBar = context.getSupportActionBar();
        if (actionBar == null) return;

        actionBar.setDisplayHomeAsUpEnabled(true);
    }
}

Usage in an activity:

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

    ActionBarHelper.enableBackButton(this);
}

Google Chrome now supports this (Developer Tools > Network > [XHR item in list] Preview).

In addition, you can use a third party tool to format the json content. Here's one that presents a tree view, and here's another that merely formats the text (and does validation).

In a new ASP.Net 5 MVC project in a controller action you can still do this.Context and this.Context.Request It looks like on the Request there is no longer a Url property but the child properties (schema, host, etc) are all on the request object directly.

 public IActionResult About()
    {
        ViewBag.Message = "Your application description page.";
        var schema = this.Context.Request.Scheme;

        return View();
    }

Rather or not you want to use this.Context or inject the property is another conversation. Dependency Injection in ASP.NET vNext

how to club the 4 query's as a single query

show below query

1. total number of cases pending + 2.cases filed during this month ( base on sysdate) + total number of cases (1+2) + no. cases disposed where nse= disposed + no. of cases pending (other than nse <> disposed)

nsc = nature of case

report is taken on 06th of every month

( monthly report will be counted from 05th previous month to 05th present of present month)

column(1) is your friend.

I had this problem too. I found setting the appearance to none helped.

.class {
    appearance:none;
    -moz-appearance:none;
    -webkit-appearance:none;

EDIT: The other answer is much better than mine.

I think df['word'].value_counts() should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count should be much slower than max. Both take some time to avoid missing values. (Compare with size.)

In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.

Your code looks fine, but there are a couple of things to be aware of:

Post::find($id); acts upon the primary key, if you have set your primary key in your model to something other than id by doing:

protected  $primaryKey = 'slug';

then find will search by that key instead.

Laravel also expects the id to be an integer, if you are using something other than an integer (such as a string) you need to set the incrementing property on your model to false:

public $incrementing = false;

Use datetime.datetime.fromtimestamp:

>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'

%f directive is only supported by datetime.datetime.strftime, not by time.strftime.

UPDATE Alternative using %, str.format:

>>> import time
>>> s, ms = divmod(1236472051807, 1000)  # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'

This question is old but as it comes up high on search results I will point out that scipy has two functions for computing the binomial coefficients:

1. scipy.special.binom()

2. scipy.special.comb()

   import scipy.special
   
   # the two give the same results 
   scipy.special.binom(10, 5)
   # 252.0
   scipy.special.comb(10, 5)
   # 252.0
   
   scipy.special.binom(300, 150)
   # 9.375970277281882e+88
   scipy.special.comb(300, 150)
   # 9.375970277281882e+88
   
   # ...but with `exact == True`
   scipy.special.comb(10, 5, exact=True)
   # 252
   scipy.special.comb(300, 150, exact=True)
   # 393759702772827452793193754439064084879232655700081358920472352712975170021839591675861424
   

Note that scipy.special.comb(exact=True) uses Python integers, and therefore it can handle arbitrarily large results!

Speed-wise, the three versions give somewhat different results:

num = 300

%timeit [[scipy.special.binom(n, k) for k in range(n + 1)] for n in range(num)]
# 52.9 ms ± 107 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

%timeit [[scipy.special.comb(n, k) for k in range(n + 1)] for n in range(num)]
# 183 ms ± 814 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)each)

%timeit [[scipy.special.comb(n, k, exact=True) for k in range(n + 1)] for n in range(num)]
# 180 ms ± 649 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

(and for n = 300, the binomial coefficients are too large to be represented correctly using float64 numbers, as shown above).

var option_user_selection = document.getElementById("maincourse").options[document.getElementById("maincourse").selectedIndex ].text

I'm developing an app that needs to look similar in all devices with >= API14 when it comes to actionbar and statusbar customization. I've finally found a solution and since it took a bit of my time I'll share it to save some of yours. We start by using an appcompat-21 dependency.

Transparent Actionbar:

values/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light">
...
</style>

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="android:windowContentOverlay">@null</item>
    <item name="windowActionBarOverlay">true</item>
    <item name="colorPrimary">@android:color/transparent</item>
</style>

<style name="AppTheme.ActionBar" parent="AppTheme">
    <item name="windowActionBarOverlay">false</item>
    <item name="colorPrimary">@color/default_yellow</item>
</style>

values-v21/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    ...
</style>

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="colorPrimary">@android:color/transparent</item>
</style>

<style name="AppTheme.ActionBar" parent="AppTheme">
    <item name="colorPrimaryDark">@color/bg_colorPrimaryDark</item>
    <item name="colorPrimary">@color/default_yellow</item>
</style>

Now you can use these themes in your AndroidManifest.xml to specify which activities will have a transparent or colored ActionBar:

    <activity
            android:name=".MyTransparentActionbarActivity"
            android:theme="@style/AppTheme.ActionBar.Transparent"/>

    <activity
            android:name=".MyColoredActionbarActivity"
            android:theme="@style/AppTheme.ActionBar"/>

Note: in API>=21 to get the Actionbar transparent you need to get the Statusbar transparent too, otherwise will not respect your colour styles and will stay light-grey.

Transparent Statusbar (only works with API>=19):
This one it's pretty simple just use the following code:

protected void setStatusBarTranslucent(boolean makeTranslucent) {
        if (makeTranslucent) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        } else {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

But you'll notice a funky result:

This happens because when the Statusbar is transparent the layout will use its height. To prevent this we just need to:

SOLUTION ONE:
Add this line android:fitsSystemWindows="true" in your layout view container of whatever you want to be placed bellow the Actionbar:

    ...
        <LinearLayout
                android:fitsSystemWindows="true"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
            ...
        </LinearLayout>
    ...

SOLUTION TWO:
Add a few lines to our previous method:

protected void setStatusBarTranslucent(boolean makeTranslucent) {
        View v = findViewById(R.id.bellow_actionbar);
        if (v != null) {
            int paddingTop = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT ? MyScreenUtils.getStatusBarHeight(this) : 0;
            TypedValue tv = new TypedValue();
            getTheme().resolveAttribute(android.support.v7.appcompat.R.attr.actionBarSize, tv, true);
            paddingTop += TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
            v.setPadding(0, makeTranslucent ? paddingTop : 0, 0, 0);
        }

        if (makeTranslucent) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        } else {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

Where R.id.bellow_actionbar will be the layout container view id of whatever we want to be placed bellow the Actionbar:

...
    <LinearLayout
            android:id="@+id/bellow_actionbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

So this is it, it think I'm not forgetting something. In this example I didn't use a Toolbar but I think it'll have the same result. This is how I customize my Actionbar:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        View vg = getActionBarView();
        getWindow().requestFeature(vg != null ? Window.FEATURE_ACTION_BAR : Window.FEATURE_NO_TITLE);

        super.onCreate(savedInstanceState);
        setContentView(getContentView());

        if (vg != null) {
            getSupportActionBar().setCustomView(vg, new ActionBar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            getSupportActionBar().setDisplayShowCustomEnabled(true);
            getSupportActionBar().setDisplayShowHomeEnabled(false);
            getSupportActionBar().setDisplayShowTitleEnabled(false);
            getSupportActionBar().setDisplayUseLogoEnabled(false);
        }
        setStatusBarTranslucent(true);
    }

Note: this is an abstract class that extends ActionBarActivity
Hope it helps!

Create your own custom IsEmpty TypeSafeMatcher:

Even if the generics problems are fixed in 1.3 the great thing about this method is it works on any class that has an isEmpty() method! Not just Collections!

For example it will work on String as well!

/* Matches any class that has an <code>isEmpty()</code> method
 * that returns a <code>boolean</code> */ 
public class IsEmpty<T> extends TypeSafeMatcher<T>
{
    @Factory
    public static <T> Matcher<T> empty()
    {
        return new IsEmpty<T>();
    }

    @Override
    protected boolean matchesSafely(@Nonnull final T item)
    {
        try { return (boolean) item.getClass().getMethod("isEmpty", (Class<?>[]) null).invoke(item); }
        catch (final NoSuchMethodException e) { return false; }
        catch (final InvocationTargetException | IllegalAccessException e) { throw new RuntimeException(e); }
    }

    @Override
    public void describeTo(@Nonnull final Description description) { description.appendText("is empty"); }
}

if you are using maven:

mvn eclipse:eclipse -DdownloadSources=true  -DdownloadJavadocs=true

It's also important to realize that simply moving the program break pointer around with brk and sbrk doesn't actually allocate the memory, it just sets up the address space. On Linux, for example, the memory will be "backed" by actual physical pages when that address range is accessed, which will result in a page fault, and will eventually lead to the kernel calling into the page allocator to get a backing page.

My personal favorite alias, via .gitconfig, is:

graph = log --graph --color --all --pretty=format:"%C(yellow)%H%C(green)%d%C(reset)%n%x20%cd%n%x20%cn%x20(%ce)%n%x20%s%n"

An example of Python's way of doing "ternary" expressions:

i = 5 if a > 7 else 0

translates into

if a > 7:
   i = 5
else:
   i = 0

This actually comes in handy when using list comprehensions, or sometimes in return statements, otherwise I'm not sure it helps that much in creating readable code.

The readability issue was discussed at length in this recent SO question better way than using if-else statement in python.

It also contains various other clever (and somewhat obfuscated) ways to accomplish the same task. It's worth a read just based on those posts.

First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.

if you need pass argument to update method you can do it like this

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }

and get these arguments inside update method

update(e, space, txt){
   console.log(e.target, space, txt);
}

Example

event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset

<button 
  data-space="home" 
  className="home" 
  data-txt="Home" 
  onClick={ this.props.onClick } 
/> 
  Button
</button>

onClick(e) {
   console.log(e.target.dataset.txt, e.target.dataset.space);
}

Example

you are a PyCharm User, its good easy to install Flask First open the pycharm press Open Settings(Ctrl+Alt+s) Goto Project Interpreter

Double click pip>>

We have the following benefits of using IHttpActionResult over HttpResponseMessage:

1. By using the IHttpActionResult we are only concentrating on the data to be send not on the status code. So here the code will be cleaner and very easy to maintain.
2. Unit testing of the implemented controller method will be easier.
3. Uses async and await by default.

You'd better create some class for each item instead of using anonymous objects. And in object you're serializing you should have array of those items. E.g.:

public class Item
{
    public string name { get; set; }
    public string index { get; set; }
    public string optional { get; set; }
}

public class RootObject
{
    public List<Item> items { get; set; }
}

Usage:

var objectToSerialize = new RootObject();
objectToSerialize.items = new List<Item> 
                          {
                             new Item { name = "test1", index = "index1" },
                             new Item { name = "test2", index = "index2" }
                          };

And in the result you won't have to change things several times if you need to change data-structure.

p.s. Here's very nice tool for complex jsons

In my case it was because I didn't connect to databases yet when first opened solution. click connection manager tab, establish connection to every datasource in that tab, run project

The code for percent sign in NSString format is %%. This is also true for NSLog() and printf() formats.

Thats an if/else statement equilavent to

if(row % 2 == 1){
  System.out.print("<");
}else{
  System.out.print("\r>");
}

For deep nested object you can use my snippet for lodash > 4

const removeObjectsWithNull = (obj) => {
    return _(obj)
      .pickBy(_.isObject) // get only objects
      .mapValues(removeObjectsWithNull) // call only for values as objects
      .assign(_.omitBy(obj, _.isObject)) // save back result that is not object
      .omitBy(_.isNil) // remove null and undefined from object
      .value(); // get value
};

Why do you need to state both 'x' and 'y' before the ':'?

Because a lambda is (conceptually) the same as a function, just written inline. Your example is equivalent to

def f(x, y) : return x + y

just without binding it to a name like f.

Also how do you make it return multiple arguments?

The same way like with a function. Preferably, you return a tuple:

lambda x, y: (x+y, x-y)

Or a list, or a class, or whatever.

The thing with self.entry_1.bind should be answered by Demosthenex.

I had problems with the mentioned methods when I use an array like

var array = ['foo', 'bar', 'foobar'];
var filled = array.fill(7);

//filled should be ['foo', 'bar', 'foobar', 'foo', 'bar', 'foobar', 'foo']

To get this I'm using:

Array.prototype.fill = function(val){
    var l = this.length;
    if(l < val){
        for(var i = val-1-l; i >= 0; i--){
            this[i+l] = this[i % l];
        }
    }
    return this;
};

We passed Json object by HttpPost method, and parse it in dynamic object. it works fine. this is sample code:

webapi:

[HttpPost]
public string DoJson2(dynamic data)
{
   //whole:
   var c = JsonConvert.DeserializeObject<YourObjectTypeHere>(data.ToString()); 

   //or 
   var c1 = JsonConvert.DeserializeObject< ComplexObject1 >(data.c1.ToString());

   var c2 = JsonConvert.DeserializeObject< ComplexObject2 >(data.c2.ToString());

   string appName = data.AppName;
   int appInstanceID = data.AppInstanceID;
   string processGUID = data.ProcessGUID;
   int userID = data.UserID;
   string userName = data.UserName;
   var performer = JsonConvert.DeserializeObject< NextActivityPerformers >(data.NextActivityPerformers.ToString());

   ...
}

The complex object type could be object, array and dictionary.

ajaxPost:
...
Content-Type: application/json,
data: {"AppName":"SamplePrice",
       "AppInstanceID":"100",
       "ProcessGUID":"072af8c3-482a-4b1c??-890b-685ce2fcc75d",
       "UserID":"20",
       "UserName":"Jack",
       "NextActivityPerformers":{
           "39??c71004-d822-4c15-9ff2-94ca1068d745":[{
                 "UserID":10,
                 "UserName":"Smith"
           }]
       }}
...

I'm going to give the short answer since everyone else gave the long one.

You'll get .select and .activate whenever you record macros and reuse them. When you .select a cell or sheet it just makes it active. From that point on whenever you use unqualified references like Range.Value they just use the active cell and sheet. This can also be problematic if you don't watch where your code is placed or a user clicks on the workbook.

So, you can eliminate these issues by directly referencing your cells. Which goes:

'create and set a range
Dim Rng As Excel.Range
Set Rng = Workbooks("Book1").Worksheets("Sheet1").Range("A1")
'OR
Set Rng = Workbooks(1).Worksheets(1).Cells(1, 1)

Or you could

'Just deal with the cell directly rather than creating a range
'I want to put the string "Hello" in Range A1 of sheet 1
Workbooks("Book1").Worksheets("Sheet1").Range("A1").value = "Hello"
'OR
Workbooks(1).Worksheets(1).Cells(1, 1).value = "Hello"

There are various combinations of these methods, but that would be the general idea expressed as shortly as possible for impatient people like me.

While this is definitely not the optimal solution to the problem, it is another potential solution which I thought some people might find interesting:

    Double kea = kElement2( t.getLeftSon(), k, treeSize, count );

    if ( kea != Double.POSITIVE_INFINITY )
        return kea;

You need to publish the exposed ports by using the following options:

-P (upper case) or --publish-all that will tell Docker to use random ports from your host and map them to the exposed container's ports.

-p (lower case) or --publish=[] that will tell Docker to use ports you manually set and map them to the exposed container's ports.

The second option is preferred because you already know which ports are mapped. If you use the first option then you will need to call docker inspect demo and check which random ports are being used from your host at the Ports section.

Just run the following command:

docker run -it -p 8080:8080 demo

After that your url will work.

I'm using get-json very simple to use:

$ npm install get-json --save

Import get-json

var getJSON = require('get-json')

To do a GET request you would do something like:

getJSON('http://api.listenparadise.org', function(error, response){
    console.log(response);
})

Here it is:

function call_func(input) {
    var evaled = eval('(' + input + ')');
    var newDiv = document.createElement('div');
    var id = evaled.id;
    var name = evaled.Student_name;
    var dob = evaled.student_dob;
    var html = '<b>ID:</b>';
    html += '<a href="/learningyii/index.php?r=student/view&amp; id=' + id + '">' + id + '</a>';
    html += '<br/>';
    html += '<b>Student Name:</b>';
    html += name;
    html += '<br/>';
    html += '<b>Student DOB:</b>';
    html += dob;
    html += '<br/>';
    newDiv.innerHTML = html;
    newDiv.setAttribute('class', 'view');
    $('#StudentGridViewId').find('.items').prepend(newDiv);
};

Even though du usually prints disk usage and not actual data size, GNU coreutils du can print file's "apparent size" in bytes:

du -b FILE

But it won't work under BSD, Solaris, macOS, ...

Try this code, it works perfectly.

var IDLE_TIMEOUT = 10; //seconds
var _idleSecondsCounter = 0;

document.onclick = function () {
    _idleSecondsCounter = 0;
};

document.onmousemove = function () {
    _idleSecondsCounter = 0;
};

document.onkeypress = function () {
    _idleSecondsCounter = 0;
};

window.setInterval(CheckIdleTime, 1000);

function CheckIdleTime() {
    _idleSecondsCounter++;
    var oPanel = document.getElementById("SecondsUntilExpire");
    if (oPanel)
        oPanel.innerHTML = (IDLE_TIMEOUT - _idleSecondsCounter) + "";
    if (_idleSecondsCounter >= IDLE_TIMEOUT) {
        alert("Time expired!");
        document.location.href = "SessionExpired.aspx";
    }
}

Arguably, it is an example of syntactic sugar, since it is implemented as an array anyways (which doesn't mean it's useless) - I prefer passing an array to keep it clear, and also declare methods with arrays of given type. Rather an opinion than an answer, though.

You may find an answer with this example : errorbar_demo_features.py

"""
Demo of errorbar function with different ways of specifying error bars.

Errors can be specified as a constant value (as shown in `errorbar_demo.py`),
or as demonstrated in this example, they can be specified by an N x 1 or 2 x N,
where N is the number of data points.

N x 1:
    Error varies for each point, but the error values are symmetric (i.e. the
    lower and upper values are equal).

2 x N:
    Error varies for each point, and the lower and upper limits (in that order)
    are different (asymmetric case)

In addition, this example demonstrates how to use log scale with errorbar.
"""
import numpy as np
import matplotlib.pyplot as plt

# example data
x = np.arange(0.1, 4, 0.5)
y = np.exp(-x)
# example error bar values that vary with x-position
error = 0.1 + 0.2 * x
# error bar values w/ different -/+ errors
lower_error = 0.4 * error
upper_error = error
asymmetric_error = [lower_error, upper_error]

fig, (ax0, ax1) = plt.subplots(nrows=2, sharex=True)
ax0.errorbar(x, y, yerr=error, fmt='-o')
ax0.set_title('variable, symmetric error')

ax1.errorbar(x, y, xerr=asymmetric_error, fmt='o')
ax1.set_title('variable, asymmetric error')
ax1.set_yscale('log')
plt.show()

Which plots this:

Extended sort key columns

The reason why what you want to do doesn't work is because of the logical order of operations in SQL, which, for your first query, is (simplified):

• FROM MonitoringJob
• SELECT Category, CreationDate i.e. add a so called extended sort key column
• ORDER BY CreationDate DESC
• SELECT Category i.e. remove the extended sort key column again from the result.

So, thanks to the SQL standard extended sort key column feature, it is totally possible to order by something that is not in the SELECT clause, because it is being temporarily added to it behind the scenes.

So, why doesn't this work with DISTINCT?

If we add the DISTINCT operation, it would be added between SELECT and ORDER BY:

• FROM MonitoringJob
• SELECT Category, CreationDate
• DISTINCT
• ORDER BY CreationDate DESC
• SELECT Category

But now, with the extended sort key column CreationDate, the semantics of the DISTINCT operation has been changed, so the result will no longer be the same. This is not what we want, so both the SQL standard, and all reasonable databases forbid this usage.

Workarounds

It can be emulated with standard syntax as follows

SELECT Category
FROM (
  SELECT Category, MAX(CreationDate) AS CreationDate
  FROM MonitoringJob
  GROUP BY Category
) t
ORDER BY CreationDate DESC

Or, just simply (in this case), as shown also by Prutswonder

SELECT Category, MAX(CreationDate) AS CreationDate
FROM MonitoringJob
GROUP BY Category
ORDER BY CreationDate DESC

I have blogged about SQL DISTINCT and ORDER BY more in detail here.

Accurate and fast will give output in seconds:

 let startDate = new Date()
 let endDate = new Date("yyyy-MM-dd'T'HH:mm:ssZ");
 let seconds = Math.round((endDate.getTime() - startDate.getTime()) / 1000);

My Code Is Very Easy To Understand

}

For anyone using Windows 10 and nothing else working for him/her:

In my case, I had to clone the repo with https instead of ssh and a window popped-up asking for my credentials. After that everything works fine.

If you are using oc4j to deploy the ear.

Make sure you set in the project the correct path for deploy.home=

You can fiind deploy.home in common.properties file

The oc4j needs to reload the new created class in the ear so that the server class and the client class have the same serialVersionUID

For me this started happening because on a project, I was using Docker image mysql:latest (which was version 5, and which was working fine), and during a later build, the latest version was switched to version 8, and stopped working. I changed my image to mysql:5 and I was no longer getting this error.

The following should be clean (using find_package) and work (the find module is called FindThreads):

cmake_minimum_required (VERSION 2.6) 
find_package (Threads)
add_executable (myapp main.cpp ...)
target_link_libraries (myapp ${CMAKE_THREAD_LIBS_INIT})

in my case, upgrading pip did the trick. Also, I've installed scipy with -U parameter (upgrade all packages to the last available version)

No matter what we tried we couldn't manage to get the timeout below 21 seconds when the server we were checking was down.

To work around this we combined a TcpClient check to see if the domain was alive followed by a separate check to see if the URL was active

public static bool IsUrlAlive(string aUrl, int aTimeoutSeconds)
{
    try
    {
        //check the domain first
        if (IsDomainAlive(new Uri(aUrl).Host, aTimeoutSeconds))
        {
            //only now check the url itself
            var request = System.Net.WebRequest.Create(aUrl);
            request.Method = "HEAD";
            request.Timeout = aTimeoutSeconds * 1000;
            var response = (HttpWebResponse)request.GetResponse();
            return response.StatusCode == HttpStatusCode.OK;
        }
    }
    catch
    {
    }
    return false;

}

private static bool IsDomainAlive(string aDomain, int aTimeoutSeconds)
{
    try
    {
        using (TcpClient client = new TcpClient())
        {
            var result = client.BeginConnect(aDomain, 80, null, null);

            var success = result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(aTimeoutSeconds));

            if (!success)
            {
                return false;
            }

            // we have connected
            client.EndConnect(result);
            return true;

SyntaxHighlighter is a fully functional self-contained code syntax highlighter developed in JavaScript. To get an idea of what SyntaxHighlighter is capable of, have a look at the demo page.

If you just want to access the last item in the list you can do

if(integerList.Count>0)
{
   var item = integerList[integerList.Count - 1];
}

to get the total number of items in the list you can use the Count property

var itemCount = integerList.Count;

I don't know if this has really been solved or not... but by looking at all the other answers, nothing seems quite clear. The best way I found to do this is to put the same code, that was used to populate your datagridview into a method and pass it your form's datagridview, as so:

public void ConnectAndPopulateDataGridView(DataGridView dataGridView)
{ }

The code within the method is the exact same as the code used to populate the datagirdview originally, except for the datagridview name changing to whatever you called it in your method.

Now this method is called in your parent form.

The child form is launched via a .ShowDialog() then the method is called after so that it is called right after the child for is closed... as so:

ChildForm.ShowDialog();

ConnectAndPopulateDataGridView(dataGridView1);

Here is yet another, compact version, with the generics syntax:

    public static IEnumerable<T> FindLogicalChildren<T>(DependencyObject obj) where T : DependencyObject
    {
        if (obj != null) {
            if (obj is T)
                yield return obj as T;

            foreach (DependencyObject child in LogicalTreeHelper.GetChildren(obj).OfType<DependencyObject>()) 
                foreach (T c in FindLogicalChildren<T>(child)) 
                    yield return c;
        }
    }

Write-Back is a more complex one and requires a complicated Cache Coherence Protocol(MOESI) but it is worth it as it makes the system fast and efficient.

The only benefit of Write-Through is that it makes the implementation extremely simple and no complicated cache coherency protocol is required.

Here are a couple of complete working examples that build on the @bendewey & @dommer examples. I needed to tweak each one a bit to get it to work, but in case another LINQ noob is looking for working examples, here you go:

//bendewey's example using data.xml from OP

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;

class loadXMLToLINQ1
{
    static void Main( )

        //Load xml
        XDocument xdoc = XDocument.Load(@"c:\\data.xml"); //you'll have to edit your path

        //Run query
        var lv1s = from lv1 in xdoc.Descendants("level1")
           select new 
           { 
               Header = lv1.Attribute("name").Value,
               Children = lv1.Descendants("level2")
            };

        StringBuilder result = new StringBuilder(); //had to add this to make the result work
        //Loop through results
        foreach (var lv1 in lv1s)
        {
            result.AppendLine("  " + lv1.Header);
            foreach(var lv2 in lv1.Children)
            result.AppendLine("    " + lv2.Attribute("name").Value);
        }
        Console.WriteLine(result.ToString()); //added this so you could see the output on the console
    }
}

And next:

//Dommer's example, using data.xml from OP
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;

class loadXMLToLINQ
{
static void Main( )
    {
        XElement rootElement = XElement.Load(@"c:\\data.xml"); //you'll have to edit your path
        Console.WriteLine(GetOutline(0, rootElement));  
    }

static private string GetOutline(int indentLevel, XElement element)
    {
        StringBuilder result = new StringBuilder();
        if (element.Attribute("name") != null)
        {
            result = result.AppendLine(new string(' ', indentLevel * 2) + element.Attribute("name").Value);
        }
        foreach (XElement childElement in element.Elements())
        {
            result.Append(GetOutline(indentLevel + 1, childElement));
        }
        return result.ToString();
    }
}

These both compile & work in VS2010 using csc.exe version 4.0.30319.1 and give the exact same output. Hopefully these help someone else who's looking for working examples of code.

EDIT: added @eglasius' example as well since it became useful to me:

//@eglasius example, still using data.xml from OP
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;

class loadXMLToLINQ2
{
    static void Main( )
    {
        StringBuilder result = new StringBuilder(); //needed for result below
        XDocument xdoc = XDocument.Load(@"c:\\deg\\data.xml"); //you'll have to edit your path
        var lv1s = xdoc.Root.Descendants("level1"); 
        var lvs = lv1s.SelectMany(l=>
             new string[]{ l.Attribute("name").Value }
             .Union(
                 l.Descendants("level2")
                 .Select(l2=>"   " + l2.Attribute("name").Value)
              )
            );
        foreach (var lv in lvs)
        {
           result.AppendLine(lv);
        }
        Console.WriteLine(result);//added this so you could see the result
    }
}

You could just use the bound ng-model (answers[item.questID]) value itself in your ng-change method to detect if it has been checked or not.

Example:-

<input type="checkbox" ng-model="answers[item.questID]" 
     ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->

and

$scope.stateChanged = function (qId) {
   if($scope.answers[qId]){ //If it is checked
       alert('test');
   }
}

On each of your buttons you could have the following;

<input type="button" name="newWin" onclick="frmSubmitSameWin();">
<input type="button" name="SameWin" onclick="frmSubmitNewWin();">

Then have a few small js functions;

<script type="text/javascript">
function frmSubmitSameWin() {
form.target = '';
form.submit();
}


function frmSubmitNewWin() {
form.target = '_blank';
form.submit();
}
</script>

That should do the trick.

I would have put this in a comment on the accepted answer, since that's where it belongs, but I can't. So, just in case anyone gets unreliable results, this could be why.

Be careful of the accepted answer, it fails if the time_point is before the epoch.

This line of code:

std::size_t fractional_seconds = ms.count() % 1000;

will yield unexpected values if ms.count() is negative (since size_t is not meant to hold negative values).

The full error message sounds:

ERROR 1075 (42000): Incorrect table definition; there can be only one auto column and it must be defined as a key

So add primary key to the auto_increment field:

CREATE TABLE book (
   id INT AUTO_INCREMENT primary key NOT NULL,
   accepted_terms BIT(1) NOT NULL,
   accepted_privacy BIT(1) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

In 2015, if you still getting this confusing error, blame python default setuptools that PIP uses.

1. Download and install minimal Microsoft Visual C++ Compiler for Python 2.7 required to compile python 2.7 modules from http://www.microsoft.com/en-in/download/details.aspx?id=44266
2. Update your setuptools - pip install -U setuptools
3. Install whatever python package you want that require C compilation. pip install blahblah

It will work fine.

UPDATE: It won't work fine for all libraries. I still get some error with few modules, that require lib-headers. They only thing that work flawlessly is Linux platform

Try with Resource

File file = new File("Foo.txt");
try (PrintStream ps = new PrintStream(file)) {
   ps.println("Bar");
}
response.setContentType("application/octet-stream");
response.setContentLength((int) file.length());
response.setHeader( "Content-Disposition",
         String.format("attachment; filename=\"%s\"", file.getName()));

OutputStream out = response.getOutputStream();
try (FileInputStream in = new FileInputStream(file)) {
    byte[] buffer = new byte[4096];
    int length;
    while ((length = in.read(buffer)) > 0) {
        out.write(buffer, 0, length);
    }
}
out.flush();

As Thomas says, the cin ignore is a good way. To always wait for user to press enter (even if exit is used), register a function atexit:

#include <iostream>

void pause()
{   ::std::cout<<"\nPress ENTER to exit.";
    ::std::cin.sync();
    if(::std::cin.get()!='\n')
        ::std::cin.ignore(0xFFFFFFFF,'\n');
}

int main()
{
    atexit(pause);

    // whatever

    return 0;
}

Some googling found this, where people had a discussion about this.

An unsigned char is basically a single byte. So, you would use this if you need one byte of data (for example, maybe you want to use it to set flags on and off to be passed to a function, as is often done in the Windows API).

It's a member initialization list. You should find information about it in any good C++ book.

You should, in most cases, initialize all member objects in the member initialization list (however, do note the exceptions listed at the end of the FAQ entry).

The takeaway point from the FAQ entry is that,

All other things being equal, your code will run faster if you use initialization lists rather than assignment.

You have to export it from your NgModule:

@NgModule({
  declarations: [TaskCardComponent],
  exports: [TaskCardComponent],
  imports: [MdCardModule],
  providers: []
})
export class TaskModule{}

Core of the static keyword that you will have only one copy at RAM of this (method /variable /class ) that's shared for all calling

Remove "SSLv2ClientHello" from the enabled protocols on the client SSLSocket or HttpsURLConnection.

$image is in your case the value of the item and not the key. Use the following syntax to get the key too:

foreach ($images as $key => $value) {
    /* … */
}

Now you can delete the item with unset($images[$key]).

Can be seen from UI as well. Go to overview tab on table, you will see item count. Hope it helps someone.
