function getParent(event)
{
   return event.target.parentNode;
}

Examples: 1. document.body.addEventListener("click", getParent, false); returns the parent element of the current element that you have clicked.

2. If you want to use inside any function then pass your event and call the function like this : function yourFunction(event){ var parentElement = getParent(event); }

Statements a == object2 and a.equals(object2) both will always return false because a is a string while object2 is an instance of MyClass

Here's a solution that fits entirely within integers and is within about 4% of optimal (i.e. uses 1.26 random numbers in {0..4} for every one in {0..6}). The code's in Scala, but the math should be reasonably clear in any language: you take advantage of the fact that 7^9 + 7^8 is very close to 5^11. So you pick an 11 digit number in base 5, and then interpret it as a 9 digit number in base 7 if it's in range (giving 9 base 7 numbers), or as an 8 digit number if it's over the 9 digit number, etc.:

abstract class RNG {
  def apply(): Int
}

class Random5 extends RNG {
  val rng = new scala.util.Random
  var count = 0
  def apply() = { count += 1 ; rng.nextInt(5) }
}

class FiveSevener(five: RNG) {
  val sevens = new Array[Int](9)
  var nsevens = 0
  val to9 = 40353607;
  val to8 = 5764801;
  val to7 = 823543;
  def loadSevens(value: Int, count: Int) {
    nsevens = 0;
    var remaining = value;
    while (nsevens < count) {
      sevens(nsevens) = remaining % 7
      remaining /= 7
      nsevens += 1
    }
  }
  def loadSevens {
    var fivepow11 = 0;
    var i=0
    while (i<11) { i+=1 ; fivepow11 = five() + fivepow11*5 }
    if (fivepow11 < to9) { loadSevens(fivepow11 , 9) ; return }
    fivepow11 -= to9
    if (fivepow11 < to8) { loadSevens(fivepow11 , 8) ; return }
    fivepow11 -= to8
    if (fivepow11 < 3*to7) loadSevens(fivepow11 % to7 , 7)
    else loadSevens
  }
  def apply() = {
    if (nsevens==0) loadSevens
    nsevens -= 1
    sevens(nsevens)
  }
}

If you paste a test into the interpreter (REPL actually), you get:

scala> val five = new Random5
five: Random5 = Random5@e9c592

scala> val seven = new FiveSevener(five)
seven: FiveSevener = FiveSevener@143c423

scala> val counts = new Array[Int](7)
counts: Array[Int] = Array(0, 0, 0, 0, 0, 0, 0)

scala> var i=0 ; while (i < 100000000) { counts( seven() ) += 1 ; i += 1 }
i: Int = 100000000

scala> counts
res0: Array[Int] = Array(14280662, 14293012, 14281286, 14284836, 14287188,
14289332, 14283684)

scala> five.count
res1: Int = 125902876

The distribution is nice and flat (within about 10k of 1/7 of 10^8 in each bin, as expected from an approximately-Gaussian distribution).

It's not your specific case, but it's worth noting for anybody else that this error can occur if you try to reference some fields in a table that are not the whole primary key of that table. Obviously this is not allowed.

You can't. With inline styles you are targeting the element directly. You can't use other selectors there.

What you can do however is define different classes in your stylesheet that define different colours and then add the class to the element.

Google Play Developers Console actually gives you the Stack traces from those apps that have crashed and had sent the reports, it has also a very good charts to help you see the information, see example below:

Add relative positioning to the wrapping div tag, then absolutely position the image within it like this:

CSS:

.div-wrapper {
    position: relative;
    height: 300px;
    width: 300px;
}

.div-wrapper img {
    position: absolute;
    left: 0;
    bottom: 0;
}

HTML:

<div class="div-wrapper">
    <img src="blah.png"/>
</div>

Now the image sits at the bottom of the div.

If you don't declare a function and it only appears after being called, it is automatically assumed to be int, so in your case, you didn't declare

void my_print (char *);
void my_print2 (char *);

before you call it in main, so the compiler assume there are functions which their prototypes are int my_print2 (char *); and int my_print2 (char *); and you can't have two functions with the same prototype except of the return type, so you get the error of conflicting types.

As Brian suggested, declare those two methods before main.

Here's one possible method.

function isMouseInBox(e) {
  var textbox = document.getElementById('textbox');

  // Box position & sizes
  var boxX = textbox.offsetLeft;
  var boxY = textbox.offsetTop;
  var boxWidth = textbox.offsetWidth;
  var boxHeight = textbox.offsetHeight;

  // Mouse position comes from the 'mousemove' event
  var mouseX = e.pageX;
  var mouseY = e.pageY;
  if(mouseX>=boxX && mouseX<=boxX+boxWidth) {
    if(mouseY>=boxY && mouseY<=boxY+boxHeight){
       // Mouse is in the box
       return true;
    }
  }
}

document.addEventListener('mousemove', function(e){
    isMouseInBox(e);
})

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

Edit Since version 26 of the support library (or androidx) you no longer need to implement a custom OnLongClickListener to display the tooltip. Simply call this:

TooltipCompat.setTooltipText(menu_hotlist, getString(R.string.hint_show_hot_message));

I'll just share my code in case someone wants something like this:

• layout/menu/menu_actionbar.xml

  <?xml version="1.0" encoding="utf-8"?>
  
  <menu xmlns:android="http://schemas.android.com/apk/res/android">

      ...
  </menu>
  

• layout/action_bar_notifitcation_icon.xml

  Note style and android:clickable properties. these make the layout the size of a button and make the background gray when touched.

  A 64x64 pixel image with 10 pixel wide paddings from all sides. You are supposed to have 8 pixel wide paddings, but I find most default items being slightly smaller than that. Of course, you'll want to use different sizes for different densities.

  Here we make it clickable and updatable! I created an abstract listener that provides Toast creation on onLongClick, the code was taken from from the sources of ActionBarSherlock.

  private int hot_number = 0;
  private TextView ui_hot = null;
  
  @Override public boolean onCreateOptionsMenu(final Menu menu) {
      MenuInflater menuInflater = getSupportMenuInflater();
      menuInflater.inflate(R.menu.menu_actionbar, menu);
      final View menu_hotlist = menu.findItem(R.id.menu_hotlist).getActionView();
      ui_hot = (TextView) menu_hotlist.findViewById(R.id.hotlist_hot);
      updateHotCount(hot_number);
      new MyMenuItemStuffListener(menu_hotlist, "Show hot message") {
          @Override
          public void onClick(View v) {
              onHotlistSelected();
          }
      };
      return super.onCreateOptionsMenu(menu);
  }
  
  // call the updating code on the main thread,
  // so we can call this asynchronously
  public void updateHotCount(final int new_hot_number) {
      hot_number = new_hot_number;
      if (ui_hot == null) return;
      runOnUiThread(new Runnable() {
          @Override
          public void run() {
              if (new_hot_number == 0)
                  ui_hot.setVisibility(View.INVISIBLE);
              else {
                  ui_hot.setVisibility(View.VISIBLE);
                  ui_hot.setText(Integer.toString(new_hot_number));
              }
          }
      });
  }
  
  static abstract class MyMenuItemStuffListener implements View.OnClickListener, View.OnLongClickListener {
      private String hint;
      private View view;
  
      MyMenuItemStuffListener(View view, String hint) {
          this.view = view;
          this.hint = hint;
          view.setOnClickListener(this);
          view.setOnLongClickListener(this);
      }
  
      @Override abstract public void onClick(View v);
  
      @Override public boolean onLongClick(View v) {
          final int[] screenPos = new int[2];
          final Rect displayFrame = new Rect();
          view.getLocationOnScreen(screenPos);
          view.getWindowVisibleDisplayFrame(displayFrame);
          final Context context = view.getContext();
          final int width = view.getWidth();
          final int height = view.getHeight();
          final int midy = screenPos[1] + height / 2;
          final int screenWidth = context.getResources().getDisplayMetrics().widthPixels;
          Toast cheatSheet = Toast.makeText(context, hint, Toast.LENGTH_SHORT);
          if (midy < displayFrame.height()) {
              cheatSheet.setGravity(Gravity.TOP | Gravity.RIGHT,
                      screenWidth - screenPos[0] - width / 2, height);

Generally, it is assumed that name is always superseded by id. This is true, to some extent, but not for form fields and frame names, practically speaking. For example, with form elements the name attribute is used to determine the name-value pairs to be sent to a server-side program and should not be eliminated. Browsers do not use id in that manner. To be on the safe side, you could use name and id attributes on form elements. So, we would write the following:

<form id="myForm" name="myForm">
     <input type="text" id="userName" name="userName" />
</form>

To ensure compatibility, having matching name and id attribute values when both are defined is a good idea. However, be careful—some tags, particularly radio buttons, must have nonunique name values, but require unique id values. Once again, this should reference that id is not simply a replacement for name; they are different in purpose. Furthermore, do not discount the old-style approach, a deep look at modern libraries shows such syntax style used for performance and ease purposes at times. Your goal should always be in favor of compatibility.

Now in most elements, the name attribute has been deprecated in favor of the more ubiquitous id attribute. However, in some cases, particularly form fields (<button>, <input>, <select>, and <textarea>), the name attribute lives on because it continues to be required to set the name-value pair for form submission. Also, we find that some elements, notably frames and links, may continue to use the name attribute because it is often useful for retrieving these elements by name.

There is a clear distinction between id and name. Very often when name continues on, we can set the values the same. However, id must be unique, and name in some cases shouldn’t—think radio buttons. Sadly, the uniqueness of id values, while caught by markup validation, is not as consistent as it should be. CSS implementation in browsers will style objects that share an id value; thus, we may not catch markup or style errors that could affect our JavaScript until runtime.

This is taken from the book JavaScript- The Complete Reference by Thomas-Powell

Same result you can achieve using the Splitter class.

var list = Splitter.on(",").splitToList(YourStringVariable)

(written in kotlin)

Maybe some AJAX page content injection could be used as an alternative, though I still can't get around why your teacher would refuse to rid the website of frames.

Additionally, is there any specific reason you personally want to us HTML5?

But if not, I believe <iframe>s are still around.

anytree

I recommend https://pypi.python.org/pypi/anytree

Example

from anytree import Node, RenderTree

udo = Node("Udo")
marc = Node("Marc", parent=udo)
lian = Node("Lian", parent=marc)
dan = Node("Dan", parent=udo)
jet = Node("Jet", parent=dan)
jan = Node("Jan", parent=dan)
joe = Node("Joe", parent=dan)

print(udo)
Node('/Udo')
print(joe)
Node('/Udo/Dan/Joe')

for pre, fill, node in RenderTree(udo):
    print("%s%s" % (pre, node.name))
Udo
+-- Marc
¦   +-- Lian
+-- Dan
    +-- Jet
    +-- Jan
    +-- Joe

print(dan.children)
(Node('/Udo/Dan/Jet'), Node('/Udo/Dan/Jan'), Node('/Udo/Dan/Joe'))

Features

anytree has also a powerful API with:

• simple tree creation
• simple tree modification
• pre-order tree iteration
• post-order tree iteration
• resolve relative and absolute node paths
• walking from one node to an other.
• tree rendering (see example above)
• node attach/detach hookups

It is actually very simple,

php -q /home/username/public_html/cron/cron.php

For those working on fragments and it disappeared after setting toolbar.getBackground().setAlpha(0); or any disappearance, i think you have to bring your AppBarLayout to the last in the xml, so its Fragment then AppBarLayout then relativelayout/constraint/linear whichever u use.

This should work

 <a href="#" onclick="function hi(){alert('Hi!')};hi()">click</a>

You may inline any javascript inside the onclick as if you were assigning the method through javascript. I think is just a matter of making code cleaner keeping your js inside a script block

export in sh and related shells (such as bash), marks an environment variable to be exported to child-processes, so that the child inherits them.

export is defined in POSIX:

The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.

Use Integer instead.

HashMap<Integer, MyObject> myMap = new HashMap<Integer, MyObject>();

Java will automatically autobox your int primitive values to Integer objects.

Read more about autoboxing from Oracle Java documentations.

select * from tblErrorLog
where errorDate BETWEEN '12/20/2008' AND DATEADD(DAY, 1, '12/20/2008')

How about using a COUNT OVER (PARTITION BY {column to group by}) partitioning function in SQL Server?

For example, if you want to group product sales by ItemID and you want a count of each distinct ItemID, simply use:

SELECT
{columns you want} ,
COUNT(ItemID) OVER (PARTITION BY ItemID) as BandedItemCount ,
{more columns you want}... ,
FROM {MyTable}

If you use this approach, you can leave the GROUP BY out of the picture -- assuming you want to return the entire list (as you might do report banding where you need to know the entire count of items you are going to band without having to display the entire set of data, i.e. Reporting Services).

You can also get the value of an item in the jObject like this:

JToken value;
if (json.TryGetValue(key, out value))
{
   DoSomething(value);
}

Recursion in Python works just as recursion in an other language, with the recursive construct defined in terms of itself:

For example a recursive class could be a binary tree (or any tree):

class tree():
    def __init__(self):
        '''Initialise the tree'''
        self.Data = None
        self.Count = 0
        self.LeftSubtree = None
        self.RightSubtree = None

    def Insert(self, data):
        '''Add an item of data to the tree'''
        if self.Data == None:
            self.Data = data
            self.Count += 1
        elif data < self.Data:
            if self.LeftSubtree == None:
                # tree is a recurive class definition
                self.LeftSubtree = tree()
            # Insert is a recursive function
            self.LeftSubtree.Insert(data)
        elif data == self.Data:
            self.Count += 1
        elif data > self.Data:
            if self.RightSubtree == None:
                self.RightSubtree = tree()
            self.RightSubtree.Insert(data)

if __name__ == '__main__':
    T = tree()
    # The root node
    T.Insert('b')
    # Will be put into the left subtree
    T.Insert('a')
    # Will be put into the right subtree
    T.Insert('c')

As already mentioned a recursive structure must have a termination condition. In this class, it is not so obvious because it only recurses if new elements are added, and only does it a single time extra.

Also worth noting, python by default has a limit to the depth of recursion available, to avoid absorbing all of the computer's memory. On my computer this is 1000. I don't know if this changes depending on hardware, etc. To see yours :

import sys
sys.getrecursionlimit()

and to set it :

import sys #(if you haven't already)
sys.setrecursionlimit()

edit: I can't guarentee that my binary tree is the most efficient design ever. If anyone can improve it, I'd be happy to hear how

Solution #1 (Older) (not recommended)

Firstly install ffmpeg-php project (http://ffmpeg-php.sourceforge.net/)

And then you can use of this simple code:

<?php
$frame = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$mov = new ffmpeg_movie($movie);
$frame = $mov->getFrame($frame);
if ($frame) {
    $gd_image = $frame->toGDImage();
    if ($gd_image) {
        imagepng($gd_image, $thumbnail);
        imagedestroy($gd_image);
        echo '<img src="'.$thumbnail.'">';
    }
}
?>

Description: This project use binary extension .so file, It's very old and last update was for 2008. So, maybe don't works with newer version of FFMpeg or PHP.

Solution #2 (Update 2018) (recommended)

Firstly install PHP-FFMpeg project (https://github.com/PHP-FFMpeg/PHP-FFMpeg)
(just run for install: composer require php-ffmpeg/php-ffmpeg)

And then you can use of this simple code:

<?php
require 'vendor/autoload.php';

$sec = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);
echo '<img src="'.$thumbnail.'">';

Description: It's newer and more modern project and works with latest version of FFMpeg and PHP. Note that it's required to proc_open() PHP function.

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

I think you are talking about ctrl + shift + F, by default it should be on "look in: entire solution" and there you go.

The simplest and easiest thing to do is simply delete the

node_modules

And make sure your internet is stable then run:

npm install @amcharts/amcharts4

OR, if you are using yarn

yarn add @amcharts/amcharts4

This worked for me seamlessly.

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

Because you send custom headers so your CORS request is not a simple request, so the browser first sends a preflight OPTIONS request to check that the server allows your request.

If you turn on CORS on the server then your code will work. You can also use JavaScript fetch instead (here)

IDLE's console does not support ANSI escape sequences, or any other form of escapes for coloring your output.

You can learn how to talk to IDLE's console directly instead of just treating it like normal stdout and printing to it (which is how it does things like color-coding your syntax), but that's pretty complicated. The idle documentation just tells you the basics of using IDLE itself, and its idlelib library has no documentation (well, there is a single line of documentation—"(New in 2.3) Support library for the IDLE development environment."—if you know where to find it, but that isn't very helpful). So, you need to either read the source, or do a whole lot of trial and error, to even get started.

Alternatively, you can run your script from the command line instead of from IDLE, in which case you can use whatever escape sequences your terminal handles. Most modern terminals will handle at least basic 16/8-color ANSI. Many will handle 16/16, or the expanded xterm-256 color sequences, or even full 24-bit colors. (I believe gnome-terminal is the default for Ubuntu, and in its default configuration it will handle xterm-256, but that's really a question for SuperUser or AskUbuntu.)

Learning to read the termcap entries to know which codes to enter is complicated… but if you only care about a single console—or are willing to just assume "almost everything handles basic 16/8-color ANSI, and anything that doesn't, I don't care about", you can ignore that part and just hardcode them based on, e.g., this page.

Once you know what you want to emit, it's just a matter of putting the codes in the strings before printing them.

But there are libraries that can make this all easier for you. One really nice library, which comes built in with Python, is curses. This lets you take over the terminal and do a full-screen GUI, with colors and spinning cursors and anything else you want. It is a little heavy-weight for simple uses, of course. Other libraries can be found by searching PyPI, as usual.

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

These answers are all way too complicated!

The way he wrote the method is fine. The problem is where he invoked the method. He did not include parentheses after the method name, so the compiler thought he was trying to get a value from a variable instead of a method.

In Visual Basic and Delphi, those parentheses are optional, but in C#, they are required. So, to correct the last line of the original post:

Console.WriteLine("{0}", x.fullNameMethod());

I think what BrandonS wants is not the position of the mouse relative to the root element, but rather the position of some descendant element.

For that, there is the TransformToAncestor method:

Point relativePoint = myVisual.TransformToAncestor(rootVisual)
                              .Transform(new Point(0, 0));

Where myVisual is the element that was just double-clicked, and rootVisual is Application.Current.MainWindow or whatever you want the position relative to.

You can't change img tag's src attribute using CSS. Possible using Javascript onmouseover() event handler.

HTML:

<img id="my-img" src="http://dummyimage.com/100x100/000/fff" onmouseover='hover()'/>

Javascript:

function hover() {
  document.getElementById("my-img").src = "http://dummyimage.com/100x100/eb00eb/fff";
}

It can be done using SQL Server Import and Export Wizard. But if you're familiar with SSIS and don't want to run the SQL Server Import and Export Wizard, create an SSIS package that uses the Excel Source and the SQL Server Destination in the data flow.

There's a few ways, the most prominent being getting form data, or getting the query string. Here's one method using JavaScript. When you click on a link it will call the _vals('mytarget', 'theval') which will submit the form data. When your page posts back you can check if this form data has been set and then retrieve it from the form values.

<script language="javascript" type="text/javascript">
 function _vals(target, value){
   form1.all("target").value=target;
   form1.all("value").value=value;
   form1.submit();
 }
</script>

Alternatively you can get it via the query string. PHP has your _GET and _SET global functions to achieve this making it much easier.

I'm sure there's probably more methods which are better, but these are just a few that spring to mind.

EDIT: Building on this from what others have said using the above method you would have an anchor tag like

<a onclick="_vals('name', 'val')" href="#">My Link</a>

And then in your PHP you can get form data using

$val = $_POST['value'];

So when you click on the link which uses JavaScript it will post form data and when the page posts back from this click you can then retrieve it from the PHP.

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

If you want to show the name of processes and kill them by the command of the kill, I recommended using this script to kill all python3 running process and set your ram memory free :

ps auxww | grep 'python3' | awk '{print $2}' | xargs kill -9

This should be working. Please have a look at this fiddle.

Make sure you're loading the libraries in this order: jQuery, jQuery UI CSS, jQuery UI, AngularJS.

You can delete the archive files and executable binaries that go install (or go get) produces for a package with go clean -i importpath.... These normally reside under $GOPATH/pkg and $GOPATH/bin, respectively.

Be sure to include ... on the importpath, since it appears that, if a package includes an executable, go clean -i will only remove that and not archive files for subpackages, like gore/gocode in the example below.

Source code then needs to be removed manually from $GOPATH/src.

go clean has an -n flag for a dry run that prints what will be run without executing it, so you can be certain (see go help clean). It also has a tempting -r flag to recursively clean dependencies, which you probably don't want to actually use since you'll see from a dry run that it will delete lots of standard library archive files!

A complete example, which you could base a script on if you like:

$ go get -u github.com/motemen/gore

$ which gore
/Users/ches/src/go/bin/gore

$ go clean -i -n github.com/motemen/gore...
cd /Users/ches/src/go/src/github.com/motemen/gore

I bought a MacBook Pro yesterday (Mac OS X v10.8 (Mountain Lion)) and there is no JDK installed by default...

As well as javac, I also found it didn't have packages such as SVN installed. It turns out you can get everything from the Apple developer page (you will need to register with your AppleID). SVN is part of the "Command Line Tools" package.

This is what happens on a fresh MacBook:

Hopefully this will help out other newbies like me ;)

I got it with an import loop:

}
@end

Yes, they can. If you do not have a rooted phone/tablet, then you could download c4droid here to compile your apps. Then, you could download Kevin Boone's KBOX here to run the program.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

Simple solution which worked for me.

1. Install Vim editor for windows.
2. Open VS 2012 project solution using Vim editor and modify the version targetting Visual studio solution 10.
3. Open solution with Visual studio 2010.. and continue with your work ;)

About the INT, TINYINT... These are different data types, INT is 4-byte number, TINYINT is 1-byte number. More information here - INTEGER, INT, SMALLINT, TINYINT, MEDIUMINT, BIGINT.

The syntax of TINYINT data type is TINYINT(M), where M indicates the maximum display width (used only if your MySQL client supports it).

Numeric Type Attributes.

Just use resize: none

textarea {
   resize: none;
}

You can also decide to resize your textareas only horizontal or vertical, this way:

textarea { resize: vertical; }

textarea { resize: horizontal; }

Finally, resize: both enables the resize grabber.

I think the hash-value is only used client-side, so you can't get it with php.

you could redirect it with javascript to php though.

I came across the same nagging error, which I realized has something to do with a cool feature PyCharm automatically detects...just add the @staticmethod decorator, and it will automatically remove that error where the method is used

We can't disable it directly but we can do the following:

1. add type="button".
2. remove the href="" attribute.
3. add disabled attribute so it shows that it's disabled by changing the cursor and it becomes dimmed.

example in PHP:

<?php
if($status=="Approved"){ 
?>
  <a type="button" class="btn btn-primary btn-xs" disabled> EDIT
     </a>
  <?php    
}else{
?>
  <a href="index.php" class="btn btn-primary btn-xs"> EDIT
    </a>
  <?php    
}
?>

Try this:

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:view.bounds];
view.layer.masksToBounds = NO;
view.layer.shadowColor = [UIColor blackColor].CGColor;
view.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
view.layer.shadowOpacity = 0.5f;
view.layer.shadowPath = shadowPath.CGPath;

First of all: The UIBezierPath used as shadowPath is crucial. If you don't use it, you might not notice a difference at first, but the keen eye will observe a certain lag occurring during events like rotating the device and/or similar. It's an important performance tweak.

Regarding your issue specifically: The important line is view.layer.masksToBounds = NO. It disables the clipping of the view's layer's sublayers that extend further than the view's bounds.

For those wondering what the difference between masksToBounds (on the layer) and the view's own clipToBounds property is: There isn't really any. Toggling one will have an effect on the other. Just a different level of abstraction.

Swift 2.2:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.blackColor().CGColor
    layer.shadowOffset = CGSizeMake(0.0, 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.CGPath
}

Swift 3:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.black.cgColor
    layer.shadowOffset = CGSize(width: 0.0, height: 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.cgPath
}

Create an array of object like this:

var nietos = [];
nietos.push({"01": nieto.label, "02": nieto.value});
return nietos;

First you create the object inside of the push method and then return the newly created array.

I usually do this and works always.

/try this/

for (i = res; i < *size-1; i++) { 

    arrb[i] = arrb[i + 1];
}

*size = *size - 1; /*in some ides size -- could give problems*/

This can be done with CSS3:

<input type="text" />

input
{
  -moz-border-radius: 15px;
 border-radius: 15px;
    border:solid 1px black;
    padding:5px;
}

However, an alternative would be to put the input inside a div with a rounded background, and no border on the input

If you're using Python3, you can try changing your (connection.json file) JSON to:

{
  "connection1": {
    "DSN": "con1",
    "UID": "abc",
    "PWD": "1234",
    "connection_string_python":"test1"
  }
  ,
  "connection2": {
    "DSN": "con2",
    "UID": "def",
    "PWD": "1234"
  }
}

Then using the following code:

connection_file = open('connection.json', 'r')
conn_string = json.load(connection_file)
conn_string['connection1']['connection_string_python'])
connection_file.close()
>>> test1

There is a way to do it slightly faster than in Yaroslav's answer by using get_operations. Here is a quick example:

import tensorflow as tf

a = tf.constant(1.3, name='const_a')
b = tf.Variable(3.1, name='variable_b')

I was facing this issue due to empty space at the end of the password(spring.rabbitmq.password=rabbit ) in spring boot application.properties got resolved on removing the empty space. Hope this checklist helps some one facing this issue.

In your first example, the C# compiler will actually translate the using statement to the following:

SqlConnection connection = new SqlConnection(connectionString));

try
{
    connection.Open();

    string storedProc = "GetData";
    SqlCommand command = new SqlCommand(storedProc, connection);
    command.CommandType = CommandType.StoredProcedure;
    command.Parameters.Add(new SqlParameter("@EmployeeID", employeeID));

    return (byte[])command.ExecuteScalar();
}
finally
{
    connection.Dispose();
}

Finally statements will always get called before a function returns and so the connection will be always closed/disposed.

So, in your second example the code will be compiled to the following:

try
{
    try
    {
        connection.Open();

        string storedProc = "GetData";
        SqlCommand command = new SqlCommand(storedProc, connection);
        command.CommandType = CommandType.StoredProcedure;
        command.Parameters.Add(new SqlParameter("@EmployeeID", employeeID));

        return (byte[])command.ExecuteScalar();
    }
    finally
    {
        connection.Dispose();
    }
}
catch (Exception)
{
}

The exception will be caught in the finally statement and the connection closed. The exception will not be seen by the outer catch clause.

As Except does not modify the list, you can use ForEach on List<T>:

list2.ForEach(item => list1.Remove(item));

It may not be the most efficient way, but it is simple, therefore readable, and it updates the original list (which is my requirement).

An Ad-Hoc Query is a query that cannot be determined prior to the moment the query is issued. It is created in order to get information when need arises and it consists of dynamically constructed SQL which is usually constructed by desktop-resident query tools.

Check: http://www.learn.geekinterview.com/data-warehouse/dw-basics/what-is-an-ad-hoc-query.html

for windows :

Ctrl + q and c for exit the running situation .

What about this.

var p = document.getElementById("p")_x000D_
p.innerText = p.innerText+" And this is addon."

<p id ="p">This is some text</p>

I came across this post w/a similar issue. My fix was to add a hidden field to hold my invalid state for me.

<input type="hidden" ng-model="vm.application.isValid" required="" />

In my case I had a nullable bool which a person had to select one of two different buttons. if they answer yes, an entity is added to the collection and the state of the button changes. Until all of the questions get answered, (one of the buttons in each of the pairs has a click) the form is not valid.

vm.hasHighSchool = function (attended) { 
  vm.application.hasHighSchool = attended;
  applicationSvc.addSchool(attended, 1, vm.application);
}

<input type="hidden" ng-model="vm.application.hasHighSchool" required="" />
<div class="row">
  <div class="col-lg-3"><label>Did You Attend High School?</label><label class="required" ng-hide="vm.application.hasHighSchool != undefined">*</label></div>
  <div class="col-lg-2">
    <button value="Yes" title="Yes" ng-click="vm.hasHighSchool(true)" class="btn btn-default" ng-class="{'btn-success': vm.application.hasHighSchool == true}">Yes</button>
    <button value="No" title="No" ng-click="vm.hasHighSchool(false)" class="btn btn-default" ng-class="{'btn-success':  vm.application.hasHighSchool == false}">No</button>
  </div>
</div>

If the column has a 0 value, you are fine, my guess is that you have a problem with a Null value, in that case you would need to use IsNull(Column, 0) to ensure it is always 0 at minimum.

You could just do it manually.

NB: might be better to use a HashMap instead of an inner class for the opts.

/** convenient "-flag opt" combination */
private class Option {
     String flag, opt;
     public Option(String flag, String opt) { this.flag = flag; this.opt = opt; }
}

static public void main(String[] args) {
    List<String> argsList = new ArrayList<String>();  
    List<Option> optsList = new ArrayList<Option>();
    List<String> doubleOptsList = new ArrayList<String>();

    for (int i = 0; i < args.length; i++) {
        switch (args[i].charAt(0)) {
        case '-':
            if (args[i].length < 2)
                throw new IllegalArgumentException("Not a valid argument: "+args[i]);
            if (args[i].charAt(1) == '-') {
                if (args[i].length < 3)
                    throw new IllegalArgumentException("Not a valid argument: "+args[i]);
                // --opt
                doubleOptsList.add(args[i].substring(2, args[i].length));
            } else {
                if (args.length-1 == i)
                    throw new IllegalArgumentException("Expected arg after: "+args[i]);
                // -opt
                optsList.add(new Option(args[i], args[i+1]));
                i++;
            }
            break;
        default:
            // arg
            argsList.add(args[i]);
            break;
        }
    }
    // etc
}

var day = value.Date; // a DateTime that will just be whole days
var time = value.TimeOfDay; // a TimeSpan that is the duration into the day

This is a generic compare method , that compares two objects of a same class for its values of it fields(keep in mind those are accessible by get method)

public static <T> void compare(T a, T b) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
    AssertionError error = null;
    Class A = a.getClass();
    Class B = a.getClass();
    for (Method mA : A.getDeclaredMethods()) {
        if (mA.getName().startsWith("get")) {
            Method mB = B.getMethod(mA.getName(),null );
            try {
                Assert.assertEquals("Not Matched = ",mA.invoke(a),mB.invoke(b));
            }catch (AssertionError e){
                if(error==null){
                    error = new AssertionError(e);
                }
                else {
                    error.addSuppressed(e);
                }
            }
        }
    }
    if(error!=null){
        throw error ;
    }
}

Edit: since you meant GOPATH, see fasmat's answer (upvoted)

As mentioned in "How do I make go find my package?", you need to put a package xxx in a directory xxx.

See the Go language spec:

package math

A set of files sharing the same PackageName form the implementation of a package.
An implementation may require that all source files for a package inhabit the same directory.

The Code organization mentions:

When building a program that imports the package "widget" the go command looks for src/pkg/widget inside the Go root, and then—if the package source isn't found there—it searches for src/widget inside each workspace in order.

(a "workspace" is a path entry in your GOPATH: that variable can reference multiple paths for your 'src, bin, pkg' to be)

(Original answer)

You also should set GOPATH to ~/go, not GOROOT, as illustrated in "How to Write Go Code".

The Go path is used to resolve import statements. It is implemented by and documented in the go/build package.

The GOPATH environment variable lists places to look for Go code.
On Unix, the value is a colon-separated string.
On Windows, the value is a semicolon-separated string.
On Plan 9, the value is a list.

That is different from GOROOT:

The Go binary distributions assume they will be installed in /usr/local/go (or c:\Go under Windows), but it is possible to install them in a different location.
If you do this, you will need to set the GOROOT environment variable to that directory when using the Go tools.

Here are 2 simple ways to calculate running total:

Approach 1: It can be written this way if your DBMS supports Analytical Functions

SELECT     id
           ,somedate
           ,somevalue
           ,runningtotal = SUM(somevalue) OVER (ORDER BY somedate ASC)
FROM       TestTable

Approach 2: You can make use of OUTER APPLY if your database version / DBMS itself does not support Analytical Functions

SELECT     T.id
           ,T.somedate
           ,T.somevalue
           ,runningtotal = OA.runningtotal
FROM       TestTable T
           OUTER APPLY (
                           SELECT   runningtotal = SUM(TI.somevalue)
                           FROM     TestTable TI
                           WHERE    TI.somedate <= S.somedate
                       ) OA;

Note:- If you have to calculate the running total for different partitions separately, it can be done as posted here: Calculating Running totals across rows and grouping by ID

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

I got this error because I didn't create my own test suite correctly:

Here is how I did it correctly:

Put this in Foobar.java:

public class Foobar{
    public int getfifteen(){
        return 15;
    }
}

Put this in FoobarTest.java:

import static org.junit.Assert.*;
import junit.framework.JUnit4TestAdapter;
import org.junit.Test;
public class FoobarTest {
    @Test
    public void mytest() {
        Foobar f = new Foobar();

        assert(15==f.getfifteen());
    }
    public static junit.framework.Test suite(){
       return new JUnit4TestAdapter(FoobarTest.class);
    }
}

Download junit4-4.8.2.jar I used the one from here:

http://www.java2s.com/Code/Jar/j/Downloadjunit4jar.htm

Compile it:

javac -cp .:./libs/junit4-4.8.2.jar Foobar.java FoobarTest.java

Run it:

el@failbox /home/el $ java -cp .:./libs/* org.junit.runner.JUnitCore FoobarTest
JUnit version 4.8.2
.
Time: 0.009    
OK (1 test)

One test passed.

Replace a string :

$str = str_replace("\n", '', $str);

u using also like, (%n, %t, All Special characters, numbers, char,. etc)

which means any thing u can replace in a string.

Do aman 2 sendfile. You only need to open the source file on the client and destination file on the server, then call sendfile and the kernel will chop and move the data.

git pull --rebase origin/master 

is a single command that can help you most of the time.

Edit: Pulls the commits from the origin/master and applies your changes upon the newly pulled branch history.

From Angular@6, you can have providedIn in an Injectable.

@Injectable({
  providedIn: 'root'
})
export class UserService {

}

Check the docs here

There are two ways to make a service a singleton in Angular:

1. Declare that the service should be provided in the application root.
2. Include the service in the AppModule or in a module that is only imported by the AppModule.

Beginning with Angular 6.0, the preferred way to create a singleton services is to specify on the service that it should be provided in the application root. This is done by setting providedIn to root on the service's @Injectable decorator:

It's an array, so you're looking for Count to test for contents.

I'd recommend

$foo.count -gt 0

The "why" of this is related to how PSH handles comparison of collection objects

Put this in C2 and copy down

=IF(ISNA(VLOOKUP(A2,$B$2:$B$65535,1,FALSE)),"not in B","")

Then if the value in A isn't in B the cell in column C will say "not in B".

The jQueryUI provides a extension to animate function that allows you to animate css class.

edit: Example here

There are also methods to add/remove/toggle class which you might also be interested in.

Assuming you do not want to restrict the rows that are returned because you are aggregating other values as well, you can do it like this:

select count(case when Position = 'Manager' then 1 else null end) as ManagerCount
from ...

Let's say within the same column you had values of Manager, Supervisor, and Team Lead, you could get the counts of each like this:

select count(case when Position = 'Manager' then 1 else null end) as ManagerCount,
    count(case when Position = 'Supervisor' then 1 else null end) as SupervisorCount,
    count(case when Position = 'Team Lead' then 1 else null end) as TeamLeadCount,
from ...

Here is a JavaScript Implementation that fakes Breadth First Traversal with Depth First recursion. I'm storing the node values at each depth inside an array, inside of a hash. If a level already exists(we have a collision), so we just push to the array at that level. You could use an array instead of a JavaScript object as well since our levels are numeric and can serve as array indices. You can return nodes, values, convert to a Linked List, or whatever you want. I'm just returning values for the sake of simplicity.

BinarySearchTree.prototype.breadthFirstRec = function() {

    var levels = {};

    var traverse = function(current, depth) {
        if (!current) return null;
        if (!levels[depth]) levels[depth] = [current.value];
        else levels[depth].push(current.value);
        traverse(current.left, depth + 1);
        traverse(current.right, depth + 1);
    };

    traverse(this.root, 0);
    return levels;
};


var bst = new BinarySearchTree();
bst.add(20, 22, 8, 4, 12, 10, 14, 24);
console.log('Recursive Breadth First: ', bst.breadthFirstRec());
/*Recursive Breadth First:  
{ '0': [ 20 ],
  '1': [ 8, 22 ],
  '2': [ 4, 12, 24 ],
  '3': [ 10, 14 ] } */

Here is an example of actual Breadth First Traversal using an iterative approach.

BinarySearchTree.prototype.breadthFirst = function() {

    var result = '',
        queue = [],
        current = this.root;

    if (!current) return null;
    queue.push(current);

    while (current = queue.shift()) {
        result += current.value + ' ';
        current.left && queue.push(current.left);
        current.right && queue.push(current.right);
    }
    return result;
};

console.log('Breadth First: ', bst.breadthFirst());
//Breadth First:  20 8 22 4 12 24 10 14

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

Output:

kothrud
katraj

Update #2:

for that true:

When TRUE, returned objects will be converted into associative arrays. for more information, click here

It's very simple. Git doesn't care about what's the name of its directory. It only cares what's inside. So you can simply do:

# copy the directory into newrepo dir that exists already (else create it)
$ cp -r gitrepo1 newrepo

# remove .git from old repo to delete all history and anything git from it
$ rm -rf gitrepo1/.git

Note that the copy is quite expensive if the repository is large and with a long history. You can avoid it easily too:

# move the directory instead
$ mv gitrepo1 newrepo

# make a copy of the latest version
# Either:
$ mkdir gitrepo1; cp -r newrepo/* gitrepo1/  # doesn't copy .gitignore (and other hidden files)

# Or:
$ git clone --depth 1 newrepo gitrepo1; rm -rf gitrepo1/.git

# Or (look further here: http://stackoverflow.com/q/1209999/912144)
$ git archive --format=tar --remote=<repository URL> HEAD | tar xf -

Once you create newrepo, the destination to put gitrepo1 could be anywhere, even inside newrepo if you want it. It doesn't change the procedure, just the path you are writing gitrepo1 back.

I used the code for the original basicAuth to find the answer:

app.use(function(req, res, next) {
    var user = auth(req);

    if (user === undefined || user['name'] !== 'username' || user['pass'] !== 'password') {
        res.statusCode = 401;
        res.setHeader('WWW-Authenticate', 'Basic realm="MyRealmName"');
        res.end('Unauthorized');
    } else {
        next();
    }
});

Another way is to use constant pattern matching:

if (nullableBool is true) {}
if (nullableBool is false) {}
if (nullableBool is null) {}

Unlike the operator ==, when reading the code, this will distinguish the nullable type check from ordinary "code with a smell".

This is an adaptation of the above answer, but should be more complete.

If you want to change the default for "git pull" and "git fetch" to only fetch specific branches then you can edit .git/config so that the remote config looks like:

[remote "origin"]
  fetch = +refs/heads/master:refs/remotes/origin/master

This will only fetch master from origin by default. See for more info: https://git-scm.com/book/en/v2/Git-Internals-The-Refspec

EDIT: Just realized this is the same thing that the -t option does for git remote add. At least this is a nice way to do it after the remote is added if you don't want ot delete the remote and add it again using -t.

Huffman coding generally works okay for this.

Google provides a library called the Room Persitence Library which provides a very clean way of writing SQL for Android Apps, basically an abstraction layer over underlying SQLite Database. Bellow is short code snippet from the official website:

@Dao
public interface UserDao {
    @Query("SELECT * FROM user")
    List<User> getAll();

    @Query("SELECT * FROM user WHERE uid IN (:userIds)")
    List<User> loadAllByIds(int[] userIds);

    @Query("SELECT * FROM user WHERE first_name LIKE :first AND "
           + "last_name LIKE :last LIMIT 1")
    User findByName(String first, String last);

    @Insert
    void insertAll(User... users);

    @Delete
    void delete(User user);
}

There are more examples and better documentation in the official docs for the library.

There is also one called MentaBean which is a Java ORM. It has nice features and seems to be pretty simple way of writing SQL.

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

import glob

pdf_dir = glob.glob(r'G:\personal\pdf\*')  #your pdf folder path
img_dir = "G:\\personal\\img\\"           #your dest img path

for pdf_ in pdf_dir:

        page.save(img_dir+pdf_.split("\\")[-1][:-3]+"jpg", 'JPEG')

Programs to monitor if a process on a system is running.

Script is stored in crontab and runs once every minute.

This works with if process is not running or process is running multiple times:

#! /bin/bash

case "$(pidof amadeus.x86 | wc -w)" in

0)  echo "Restarting Amadeus:     $(date)" >> /var/log/amadeus.txt
    /etc/amadeus/amadeus.x86 &
    ;;
1)  # all ok
    ;;
*)  echo "Removed double Amadeus: $(date)" >> /var/log/amadeus.txt
    kill $(pidof amadeus.x86 | awk '{print $1}')
    ;;
esac

0 If process is not found, restart it.
1 If process is found, all ok.
* If process running 2 or more, kill the last.

A simpler version. This just test if process is running, and if not restart it.

It just tests the exit flag $? from the pidof program. It will be 0 of process is running and 1 if not.

#!/bin/bash
pidof  amadeus.x86 >/dev/null
if [[ $? -ne 0 ]] ; then
        echo "Restarting Amadeus:     $(date)" >> /var/log/amadeus.txt
        /etc/amadeus/amadeus.x86 &
fi

And at last, a one liner

pidof amadeus.x86 >/dev/null ; [[ $? -ne 0 ]] && echo "Restarting Amadeus:     $(date)" >> /var/log/amadeus.txt && /etc/amadeus/amadeus.x86 &

Check that downloaded eclipse/JDK/JRE is compatible with your processor/OS architecture that is are they 32bit or 64bit?

you just need to have a wrapper for your <Text> with flex like below;

<View style={{ flex: 1 }}>

</View>

This would go up to the parent folder

cd ../

It seems to be a python bug (that works perfectly in vim). The source of the problem is the (\s*...)+ bit. Basically , you can't do (\s*)+ which make sense , because you are trying to repeat something which can be null.

>>> re.compile(r"(\s*)+")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 180, in compile

  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 233, in _compile
    raise error, v # invalid expression
sre_constants.error: nothing to repeat

However (\s*\1) should not be null, but we know it only because we know what's in \1. Apparently python doesn't ... that's weird.

I implemented this easy with a bit different approach.

My custom FragmentAdapter.getItem method returned not new MyFragment(), but the instance of MyFragment that was created in FragmentAdapter constructor.

In my activity I then got the fragment from the adapter, check if it is instanceOf needed Fragment, then cast and use needed methods.

I had this error because I wrote a wrong Class-Path in my MANIFEST.MF

I got this error on my ASP.Net 4.5 app on Windows Server 2012 R2.

Go to start menu -> "Turn windows features on or off". A wizard popped up for me.

Click Next to Server Roles

I had to check these to get this to work, located under Web Server IIS->Web Server-> Application Development (these are based on Jeremy Cook's answer above):

Then click next to Features and make sure the following is checked:

Then click next and Install. At this point, the error went away for me. Good luck!

Let's pretend you were to give me a potentially long-running task: get the names of the first five unique people you come across. This might take days if I'm in a sparsely populated area. You're not really interested in sitting on your hands while I'm running around so you say, "When you've got the list, call me on my cell and read it back to me. Here's the number.".

You've given me a callback reference--a function that I'm supposed to execute in order to hand off further processing.

In JavaScript it might look something like this:

var lottoNumbers = [];
var callback = function(theNames) {
  for (var i=0; i<theNames.length; i++) {
    lottoNumbers.push(theNames[i].length);
  }
};

db.executeQuery("SELECT name " +
                "FROM tblEveryOneInTheWholeWorld " +
                "ORDER BY proximity DESC " +
                "LIMIT 5", callback);

while (lottoNumbers.length < 5) {
  playGolf();
}
playLotto(lottoNumbers);

This could probably be improved in lots of ways. E.g., you could provide a second callback: if it ends up taking longer than an hour, call the red phone and tell the person that answers that you've timed out.

Use the CSS function from jQuery to set styles to your items :

$('#buttonId').css({ "background-color": 'brown'});

The problem was the table width. I had used width: 100% for the table. The table columns are adjusted automatically after removing the width tag.

All the previous answers are correct. Following is the little deep dive into the problem and solution.

The driver constructor in Selenium for example

WebDriver driver = new ChromeDriver();

searches for the driver executable, in this case the Google Chrome driver searches for a Chrome driver executable. In case the service is unable to find the executable, the exception is thrown.

This is where the exception comes from (note the check state method)

 /**
   *
   * @param exeName Name of the executable file to look for in PATH
   * @param exeProperty Name of a system property that specifies the path to the executable file
   * @param exeDocs The link to the driver documentation page
   * @param exeDownload The link to the driver download page
   *
   * @return The driver executable as a {@link File} object
   * @throws IllegalStateException If the executable not found or cannot be executed
   */
  protected static File findExecutable(
      String exeName,
      String exeProperty,
      String exeDocs,
      String exeDownload) {
    String defaultPath = new ExecutableFinder().find(exeName);
    String exePath = System.getProperty(exeProperty, defaultPath);
    checkState(exePath != null,
        "The path to the driver executable must be set by the %s system property;"
            + " for more information, see %s. "
            + "The latest version can be downloaded from %s",
            exeProperty, exeDocs, exeDownload);

    File exe = new File(exePath);
    checkExecutable(exe);
    return exe;
  }

The following is the check state method which throws the exception:

  /**
   * Ensures the truth of an expression involving the state of the calling instance, but not
   * involving any parameters to the calling method.
   *
   * <p>See {@link #checkState(boolean, String, Object...)} for details.
   */
  public static void checkState(
      boolean b,
      @Nullable String errorMessageTemplate,
      @Nullable Object p1,
      @Nullable Object p2,
      @Nullable Object p3) {
    if (!b) {
      throw new IllegalStateException(format(errorMessageTemplate, p1, p2, p3));
    }
  }

SOLUTION: set the system property before creating driver object as follows.

System.setProperty("webdriver.gecko.driver", "path/to/chromedriver.exe");
WebDriver driver = new ChromeDriver();

The following is the code snippet (for Chrome and Firefox) where the driver service searches for the driver executable:

Chrome:

   @Override
    protected File findDefaultExecutable() {
      return findExecutable("chromedriver", CHROME_DRIVER_EXE_PROPERTY,
          "https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver",
          "http://chromedriver.storage.googleapis.com/index.html");
    }

Firefox:

@Override
 protected File findDefaultExecutable() {
      return findExecutable(
        "geckodriver", GECKO_DRIVER_EXE_PROPERTY,
        "https://github.com/mozilla/geckodriver",
        "https://github.com/mozilla/geckodriver/releases");
    }

where CHROME_DRIVER_EXE_PROPERTY = "webdriver.chrome.driver" and GECKO_DRIVER_EXE_PROPERTY = "webdriver.gecko.driver"

Similar is the case for other browsers, and the following is the snapshot of the list of the available browser implementation:

By default, Windows makes the root of each drive available (provided you've got Administrator privileges) as (e.g.) \\server\c$. These are known as Administrative Shares.

You can use setTimeout to do this

function myFunction() {

// stop for sometime if needed
setTimeout(myFunction, 5000);

Well a cast from myObject to byte[] is never going to work unless you've got an explicit conversion or if myObject is a byte[]. You need a serialization framework of some kind. There are plenty out there, including Protocol Buffers which is near and dear to me. It's pretty "lean and mean" in terms of both space and time.

You'll find that almost all serialization frameworks have significant restrictions on what you can serialize, however - Protocol Buffers more than some, due to being cross-platform.

If you can give more requirements, we can help you out more - but it's never going to be as simple as casting...

EDIT: Just to respond to this:

I need my binary file to contain the object's bytes. Only the bytes, no metadata whatsoever. Packed object-to-object. So I'll be implementing custom serialization.

Please bear in mind that the bytes in your objects are quite often references... so you'll need to work out what to do with them.

I suspect you'll find that designing and implementing your own custom serialization framework is harder than you imagine.

I would personally recommend that if you only need to do this for a few specific types, you don't bother trying to come up with a general serialization framework. Just implement an instance method and a static method in all the types you need:

public void WriteTo(Stream stream)
public static WhateverType ReadFrom(Stream stream)

One thing to bear in mind: everything becomes more tricky if you've got inheritance involved. Without inheritance, if you know what type you're starting with, you don't need to include any type information. Of course, there's also the matter of versioning - do you need to worry about backward and forward compatibility with different versions of your types?

You should not wrap JavaScript expressions in quotes.

<option data-img-src={this.props.imageUrl} value="1">{this.props.title}</option>

Take a look at the JavaScript Expressions docs for more info.

Thanks for asking this question, simples solution is as:

// Color to Hex String

colorToHexString(Color color) {
  return '#FF${color.value.toRadixString(16).substring(2, 8)}';
}

// Hex String to Color

hexStringToColor(String hexColor) {
  hexColor = hexColor.toUpperCase().replaceAll("#", "");
  if (hexColor.length == 6) {
    hexColor = "FF" + hexColor;
  }
  return Color(int.parse(hexColor, radix: 16));
}

// How to call function

String hexCode = colorToHexString(Colors.green);
Color bgColor = hexStringToColor(hexCode);
print("$hexCode = $bgColor");

Enjoy code and help others :)

One workaround, though not a great one, is to use the new @facebook.com email address. There are a few downsides to this:

1) Not everyone (as of this posting) has the new messages application enabled in their account.

2) Not everyone will have setup their @facebook.com email in their messages app.

3) Not everyone will choose their username (if they even have a facebook username) as their email address.

I arrived to this question looking for the same but for Chromium (actually I'm using https://ungoogled-software.github.io). So in case anyone else is looking for the same:

1. Go to chrome://flags/
2. Search for Handling of extension MIME type requests
3. Select Always prompt for install
4. Search for an extension and copy its URL (something like https://chrome.google.com/webstore/detail/...)
5. Paste the URL in https://crxextractor.com/ and download the .CRX
6. Voilà, Chromium will prompt for installation

The three possible solutions suggested here have different use cases.

1. Use .equals when comparing ObjectID on two mongoDocuments like this

   results.userId.equals(AnotherMongoDocument._id)

2. Use .toString() when comparing a string representation of ObjectID to an ObjectID of a mongoDocument. like this

   results.userId === AnotherMongoDocument._id.toString()

The TableModel behind the JTable handles all of the data behind the table. In order to add and remove rows from a table, you need to use a DefaultTableModel

To create the table with this model:

JTable table = new JTable(new DefaultTableModel(new Object[]{"Column1", "Column2"}));

To add a row:

DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{"Column 1", "Column 2", "Column 3"});

You can also remove rows with this method.

Full details on the DefaultTableModel can be found here

I've had this error message show up, for completely unrelated reasons to the flags 0 or 1 mentionned in the other answers. You might be seeing it too because cv2.imread will not error out if the path string you pass it is not an image:

In [1]: import cv2
   ...: img = cv2.imread('asdfasdf')  # This is clearly not an image file
   ...: gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
   ...:

OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cv::cvtColor, file C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp, line 10638

error: C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp:10638: error: (-215) scn == 3 || scn == 4 in function cv::cvtColor

So you're seeing a cvtColor failure when it's in fact a silent imread error. Keep that in mind next time you go wasting an hour of your life with that cryptic metaphor.

You might need to check that your path string represents a valid file before passing it to cv2.imread:

import os


def read_img(path):
    """Given a path to an image file, returns a cv2 array

    str -> np.ndarray"""
    if os.path.isfile(path):
        return cv2.imread(path)
    else:
        raise ValueError('Path provided is not a valid file: {}'.format(path))


path = '2015-05-27-191152.jpg'
img = read_img(path)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Written this way, your code will fail gracefully.

In JavaScript this refers to the element containing the action. For example, if you have a function called hide():

function hide(element){
   element.style.display = 'none';
}

Calling hide with this will hide the element. It returns only the element clicked, even if it is similar to other elements in the DOM.

For example, you may have this clicking a number in the HTML below will only hide the bullet point clicked.

<ul>
  <li class="bullet" onclick="hide(this);">1</li>
  <li class="bullet" onclick="hide(this);">2</li>
  <li class="bullet" onclick="hide(this);">3</li>
  <li class="bullet" onclick="hide(this);">4</li>
</ul>

select to_number(exception_value) from exception where to_number(exception_value) = 105

Definition

A callback is executable code that is passed as an argument to other code.

Implementation

// Parent can Read
public class Parent
{
    public string Read(){ /*reads here*/ };
}

// Child need Info
public class Child
{
    private string information;
    // declare a Delegate
    delegate string GetInfo();
    // use an instance of the declared Delegate
    public GetInfo GetMeInformation;

    public void ObtainInfo()
    {
        // Child will use the Parent capabilities via the Delegate
        information = GetMeInformation();
    }
}

Usage

Parent Peter = new Parent();
Child Johny = new Child();

// Tell Johny from where to obtain info
Johny.GetMeInformation = Peter.Read;

Johny.ObtainInfo(); // here Johny 'asks' Peter to read

How about

with open(csv_input_path + file, 'r') as ft:
    header = ft.readline() # read only first line; returns string
    header_list = header.split(',') # returns list

I am assuming your input file is CSV format. If using pandas, it takes more time if the file is big size because it loads the entire data as the dataset.

Besides de color, my problem was that I was setting the text using textlabel

bt.titleLabel?.text = title

and I solved changing to:

bt.setTitle(title, for: .normal)

What Oracle version are you using? Check this page which refers to Oracle 10:

http://www.acs.ilstu.edu/docs/Oracle/server.101/b10752/stats.htm

It says:

The recommended approach to gathering statistics is to allow Oracle to automatically gather the statistics. Oracle gathers statistics on all database objects automatically and maintains those statistics in a regularly-scheduled maintenance job.

With Java8, non heap region no more contains PermGen but Metaspace, which is a major change in Java8, supposed to get rid of out of memory errors with java as metaspace size can be increased depending on the space required by jvm for class data.

Here is some pseudo-code to retrieve the following:

1. If a registry key exists
2. What the default value is for that registry key
3. What a string value is
4. What a DWORD value is

Example code:

Include the library dependency: Advapi32.lib

HKEY hKey;
LONG lRes = RegOpenKeyExW(HKEY_LOCAL_MACHINE, L"SOFTWARE\\Perl", 0, KEY_READ, &hKey);
bool bExistsAndSuccess (lRes == ERROR_SUCCESS);
bool bDoesNotExistsSpecifically (lRes == ERROR_FILE_NOT_FOUND);
std::wstring strValueOfBinDir;
std::wstring strKeyDefaultValue;
GetStringRegKey(hKey, L"BinDir", strValueOfBinDir, L"bad");
GetStringRegKey(hKey, L"", strKeyDefaultValue, L"bad");

LONG GetDWORDRegKey(HKEY hKey, const std::wstring &strValueName, DWORD &nValue, DWORD nDefaultValue)
{
    nValue = nDefaultValue;
    DWORD dwBufferSize(sizeof(DWORD));
    DWORD nResult(0);
    LONG nError = ::RegQueryValueExW(hKey,
        strValueName.c_str(),
        0,
        NULL,
        reinterpret_cast<LPBYTE>(&nResult),
        &dwBufferSize);
    if (ERROR_SUCCESS == nError)
    {
        nValue = nResult;
    }
    return nError;
}


LONG GetBoolRegKey(HKEY hKey, const std::wstring &strValueName, bool &bValue, bool bDefaultValue)
{
    DWORD nDefValue((bDefaultValue) ? 1 : 0);
    DWORD nResult(nDefValue);
    LONG nError = GetDWORDRegKey(hKey, strValueName.c_str(), nResult, nDefValue);
    if (ERROR_SUCCESS == nError)
    {
        bValue = (nResult != 0) ? true : false;
    }
    return nError;
}


LONG GetStringRegKey(HKEY hKey, const std::wstring &strValueName, std::wstring &strValue, const std::wstring &strDefaultValue)
{
    strValue = strDefaultValue;
    WCHAR szBuffer[512];
    DWORD dwBufferSize = sizeof(szBuffer);
    ULONG nError;
    nError = RegQueryValueExW(hKey, strValueName.c_str(), 0, NULL, (LPBYTE)szBuffer, &dwBufferSize);
    if (ERROR_SUCCESS == nError)
    {
        strValue = szBuffer;
    }
    return nError;
}

In my experience I have seen Enum usage sometimes cause systems to be very difficult to change. If you are using an Enum for a set of domain-specific values that change frequently, and it has a lot of other classes and components that depend on it, you might want to consider not using an Enum.

For example, a trading system that uses an Enum for markets/exchanges. There are a lot of markets out there and it's almost certain that there will be a lot of sub-systems that need to access this list of markets. Every time you want a new market to be added to your system, or if you want to remove a market, it's possible that everything under the sun will have to be rebuilt and released.

A better example would be something like a product category type. Let's say your software manages inventory for a department store. There are a lot of product categories, and many reasons why this list of categories could change. Managers may want to stock a new product line, get rid of other product lines, and possibly reorganize the categories from time to time. If you have to rebuild and redeploy all of your systems simply because users want to add a product category, then you've taken something that should be simple and fast (adding a category) and made it very difficult and slow.

Bottom line, Enums are good if the data you are representing is very static over time and has a limited number of dependencies. But if the data changes a lot and has a lot of dependencies, then you need something dynamic that isn't checked at compile time (like a database table).

Two options save vijay.sql

declare
begin
execute immediate 
'CREATE TABLE DMS_POP_WKLY_REFRESH_'||to_char(sysdate,'YYYYMMDD')||' NOLOGGING PARALLEL AS
SELECT wk.*,bbc.distance_km ,NVL(bbc.tactical_broadband_offer,0) tactical_broadband_offer ,
       sel.tactical_select_executive_flag,

AND    wk.mpn = sel.mpn (+)
AND    wk.mpn = res.mpn (+)
AND    wk.mpn = pclub.mpn (+)'
end;
/

The above will generate table names automatically based on sysdate. If you still need to pass as variable, then save vijay.sql as

declare

Use the following code:

System.out.println("\f");

'\f' is an escape sequence which represents FormFeed. This is what I have used in my projects to clear the console. This is simpler than the other codes, I guess.

I had the same issue. try this: copy to MemoryStream -> delete file -> download.

string absolutePath = "~/your path";
try {
    //copy to MemoryStream
    MemoryStream ms = new MemoryStream();
    using (FileStream fs = File.OpenRead(Server.MapPath(absolutePath))) 
    { 
        fs.CopyTo(ms); 
    }

    //Delete file
    if(File.Exists(Server.MapPath(absolutePath)))
       File.Delete(Server.MapPath(absolutePath))

    //Download file
    Response.Clear()
    Response.ContentType = "image/jpg";
    Response.AddHeader("Content-Disposition", "attachment;filename=\"" + absolutePath + "\"");
    Response.BinaryWrite(ms.ToArray())
}
catch {}

Response.End();

Formally, the correct answer is the @eumiro Solution. The problem of @HYRY solution is that when you have a sequence of numbers like [1,2,3,4] the solution is wrong, i. e., you don't have the mode. Example:

>>> import pandas as pd
>>> df = pd.DataFrame(
        {
            'client': ['A', 'B', 'A', 'B', 'B', 'C', 'A', 'D', 'D', 'E', 'E', 'E', 'E', 'E', 'A'], 
            'total': [1, 4, 3, 2, 4, 1, 2, 3, 5, 1, 2, 2, 2, 3, 4], 
            'bla': [10, 40, 30, 20, 40, 10, 20, 30, 50, 10, 20, 20, 20, 30, 40]
        }
    )

If you compute like @HYRY you obtain:

>>> print(df.groupby(['client']).agg(lambda x: x.value_counts().index[0]))
        total  bla
client            
A           4   30
B           4   40
C           1   10
D           3   30
E           2   20

Which is clearly wrong (see the A value that should be 1 and not 4) because it can't handle with unique values.

Thus, the other solution is correct:

>>> import scipy.stats
>>> print(df.groupby(['client']).agg(lambda x: scipy.stats.mode(x)[0][0]))
        total  bla
client            
A           1   10
B           4   40
C           1   10
D           3   30
E           2   20

From the looks of things you haven't passed enough data to Spring Boot to configure the datasource

Create/In your existing application.properties add the following

spring.datasource.driverClassName=
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=

making sure you append a value for each of properties.

You can find all sorts of professional code with 'break' statements in them. It perfectly make sense to use this whenever necessary. In your case this option is better than creating a separate variable just for the purpose of coming out of the loop.

$(document).ready(function(){
    var response = '';
    $.ajax({ type: "GET",   
         url: "Records.php",

         success : function(text)
         {
             response = text;
         }
    });

    alert(response);
});

needs to be:

$(document).ready(function(){

     $.ajax({ type: "GET",   
         url: "Records.php",   
         async: false,
         success : function(text)

From Java How to Program about abstract classes:

Because they’re used only as superclasses in inheritance hierarchies, we refer to them as abstract superclasses. These classes cannot be used to instantiate objects, because abstract classes are incomplete. Subclasses must declare the “missing pieces” to become “concrete” classes, from which you can instantiate objects. Otherwise, these subclasses, too, will be abstract.

To answer your question "What is the reason to use interfaces?":

An abstract class’s purpose is to provide an appropriate superclass from which other classes can inherit and thus share a common design.

As opposed to an interface:

An interface describes a set of methods that can be called on an object, but does not provide concrete implementations for all the methods... Once a class implements an interface, all objects of that class have an is-a relationship with the interface type, and all objects of the class are guaranteed to provide the functionality described by the interface. This is true of all subclasses of that class as well.

So, to answer your question "I was wondering when I should use interfaces", I think you should use interfaces when you want a full implementation and use abstract classes when you want partial pieces for your design (for reusability)

As the dictionary documentation for python 2 and python 3 would tell you, in python 2 items returns a list, while iteritems returns a iterator.

In python 3, items returns a view, which is pretty much the same as an iterator.

If you are using python 2, you may want to user iteritems if you are dealing with large dictionaries and all you want to do is iterate over the items (not necessarily copy them to a list)

To search and delete empty files in the current directory and subdirectories:

find . -type f -empty -delete

-type f is necessary because also directories are marked to be of size zero.

The dot . (current directory) is the starting search directory. If you have GNU find (e.g. not Mac OS), you can omit it in this case:

find -type f -empty -delete

From GNU find documentation:

If no files to search are specified, the current directory (.) is used.

I first tried docker and docker-compose via homebrew, but it had the problem listed here. I had to install docker's official install from https://docs.docker.com/docker-for-mac/install/ and then everything worked as expected.

To call a function inside a same controller in any laravel version follow as bellow

$role = $this->sendRequest('parameter');
// sendRequest is a public function

Unset is a function. Therefore you have to submit which variable has to be destroyed.

unset($var);

In your case

unset ($_SESSION["products"]);

If you need to reset whole session variable just call

session_destroy ();

Try to use ; instead of GO. It worked for me for 2008 R2 version

DECLARE @GLOBAL_VAR_1 INT = Value_1;

DECLARE @GLOBAL_VAR_2 INT = Value_2;

USE "DB_1";
SELECT * FROM "TABLE" WHERE "COL_!" = @GLOBAL_VAR_1 

AND "COL_2" = @GLOBAL_VAR_2;

USE "DB_2";

SELECT * FROM "TABLE" WHERE "COL_!" = @GLOBAL_VAR_2;

I would actually prefere the change event.

$('#isAgeSelected').change(function() {
    $("#txtAge").toggle(this.checked);
});

What fixed it for me: dig down to the specific solution for the project you want i.e NOT the overall solution file for all the projects.

No need to add commands anymore. For those who are new to Visual Studio Code and searching for an easy way to format code on saving, kindly follow the below steps.

1. Open Settings by pressing [Cmd+,] in Mac or using the below screenshot.

2. Type 'format' in the search box and enable the option 'Format On Save'.

You are done. Thank you.

You should use DateTime.TryParseExcact if you know the format, or if not and want to use the system settings DateTime.TryParse. And to print the date,DateTime.ToString with the right format in the argument. To get the year, month or day you have DateTime.Year, DateTime.Month or DateTime.Day.

See DateTime Structures in MSDN for additional references.

This is a well-known problem with Java type erasure: T is just a type variable, and you must indicate actual class, usually as Class argument. Without such information, best that can be done is to use bounds; and plain T is roughly same as 'T extends Object'. And Jackson will then bind JSON Objects as Maps.

In this case, tester method needs to have access to Class, and you can construct

JavaType type = mapper.getTypeFactory().
  constructCollectionType(List.class, Foo.class)

and then

List<Foo> list = mapper.readValue(new File("input.json"), type);

I know it's a bit late, but I've tried everything above and nothing worked. The real problem was that I'm using hibernate, so it was trying to connect to mysql but was not able, thats why it showed time out.

Just to let u guys know, I'm using RDS(Amazon), so just to make a test I changed to my local mysql and it worked perfectly.

Hope that this answer helps somebody.

Thanks.

A simple trick with "clearfix" CSS recommended by Bootstrap:

<div class="row">_x000D_
      <div ng-repeat-start="value in values" class="col-md-4">_x000D_
        {{value}}_x000D_
      </div>_x000D_
      <div ng-repeat-end ng-if="$index % 3 == 0" class="clearfix"></div>_x000D_
</div>

Many advantages: Efficient, fast, using Boostrap recommendations, avoiding possible $digest issues, and not altering Angular model.

Besides, multiline comments are a bitch. Sorry to say, but regardless of the language, I don't use them for anything else than debugging purposes. Say you have code like this:

void someFunction()
{
    Something
    /*Some comments*/
    Something else
}

Then you find out that there is something in your code you can't fix with the debugger, so you start manually debugging it by commenting out smaller and smaller chuncks of code with theese multiline comments. This would then give the function:

void someFunction()
{ /*
    Something
   /* Comments */
   Something more*/
}

This is really irritating.

Use this :

private string GetAlbumRSS(SyndicationItem album)
    {

        string url = "";
        foreach (SyndicationElementExtension ext in album.ElementExtensions)
            if (ext.OuterName == "itemRSS") url = ext.GetObject<string>();
        return (url);

    }
    protected void Page_Load(object sender, EventArgs e)
    {
        string albumRSS;
        string url = "http://www.SomeSite.com/rss?";
        XmlReader r = XmlReader.Create(url);
        SyndicationFeed albums = SyndicationFeed.Load(r);
        r.Close();
        foreach (SyndicationItem album in albums.Items)
        {

            cell.InnerHtml = cell.InnerHtml +string.Format("<br \'><a href='{0}'>{1}</a>", album.Links[0].Uri, album.Title.Text);
            albumRSS = GetAlbumRSS(album);

        }

    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}

If you need a 3 digit number and want 001-099 to be valid numbers you should still use randrange/randint as it is quicker than alternatives. Just add the neccessary preceding zeros when converting to a string.

import random
num = random.randrange(1, 10**3)
# using format
num_with_zeros = '{:03}'.format(num)
# using string's zfill
num_with_zeros = str(num).zfill(3)

Alternatively if you don't want to save the random number as an int you can just do it as a oneliner:

'{:03}'.format(random.randrange(1, 10**3))

python 3.6+ only oneliner:

f'{random.randrange(1, 10**3):03}'

Example outputs of the above are:

• '026'
• '255'
• '512'

Implemented as a function:

import random

def n_len_rand(len_, floor=1):
    top = 10**len_
    if floor > top:
        raise ValueError(f"Floor {floor} must be less than requested top {top}")
    return f'{random.randrange(floor, top):0{len_}}'

I was able to get rid of the message by using adding the attribute type="button" to the button element in vue.

This was considered a bug in 2013: https://jira.spring.io/browse/SPR-10180

and was fixed with version 3.2.2. Problem shouldn't occur in any versions after that and your code should work just fine.

You can use css or js for hiding a div. In else statement you can write it as:

else{
?>
<style type="text/css">#divId{
display:none;
}</style>
<?php
}

Or in jQuery

else{
?>
<script type="text/javascript">$('#divId').hide()</script>
<?php
}

Or in javascript

else{
?>
<script type="text/javascript">document.getElementById('divId').style.display = 'none';</script>
<?php
}

It's been the third time that I install Windows and npp and after some time I realize the tidy function no longer work. So I google for a solution, come to this thread, then with the help of few more so threads I finally fix it. I'll put a summary of all my actions once and for all.

1. Install TextFX plugin: Plugins -> Plugin Manager -> Show Plugin Manager. Select TextFX Characters and install. After a restart of npp, the menu 'TextFX' should be visible. (credits: @remipod).

2. Install libtidy.dll by pasting the Config folder from an old npp package: Follow instructions in this answer.

3. After having a Config folder in your latest npp installation destination (typically C:\Program Files (x86)\Notepad++\plugins), npp needs write access to that folder. Right click Config folder -> Properties -> Security tab -> select Users, click Edit -> check Full control to allow read/write access. Note that you need administrator privileges to do that.

4. Restart npp and verify TextFX -> TextFX HTML Tidy -> Tidy: Reindent XML works.

I found a way to automate running the clean before you debug your code. (Warning, this runs everytime you hit the button, even for hot restart)

1. First, find the Run > Edit Configurations Menu

2. Click the External tool '+' icon under Before launch: External tool, Activate tool window.

3. Run External Tool
4. Configure it like so. Put the working directory as a directory in your project.

      double value = 3.4555;
      String value1 =  String.format("% .3f", value) ;
      String value2 = value1.substring(0, value1.length() - 1);
      System.out.println(value2);         
      double doublevalue= Double.valueOf(value2);
      System.out.println(doublevalue);

def rescale_by_height(image, target_height, method=cv2.INTER_LANCZOS4):
    """Rescale `image` to `target_height` (preserving aspect ratio)."""
    w = int(round(target_height * image.shape[1] / image.shape[0]))
    return cv2.resize(image, (w, target_height), interpolation=method)

def rescale_by_width(image, target_width, method=cv2.INTER_LANCZOS4):
    """Rescale `image` to `target_width` (preserving aspect ratio)."""
    h = int(round(target_width * image.shape[0] / image.shape[1]))
    return cv2.resize(image, (target_width, h), interpolation=method)

If you want to do it via javascript rather than CSS you can use:

var link = document.getElementById('nav-ask');
link.style.display = 'none'; //or
link.style.visibility = 'hidden';

depending on what you want to do.

You can do it in the following way:

 myfxn <- function(var1,var2,var3){
      var1*var2*var3

    }

    lapply(1:3,myfxn,var2=2,var3=100)

and you will get the answer:

[[1]] [1] 200

[[2]] [1] 400

[[3]] [1] 600

To set to default Excel type Date (defaulted to OS level locale /-> i.e. xlsx will look different when opened by a German or British person/ and flagged with an asterisk if you choose it in Excel's cell format chooser) you should:

    CellStyle cellStyle = xssfWorkbook.createCellStyle();
    cellStyle.setDataFormat((short)14);
    cell.setCellStyle(cellStyle);

I did it with xlsx and it worked fine.

Try \vspace{-5mm} before the itemize.

Try below one:

svn copy http://svn.example.com/repos/calc/trunk@rev-no 
       http://svn.example.com/repos/calc/branches/my-calc-branch 
  -m "Creating a private branch of /calc/trunk."  --parents

No slash "\" between the svn URLs.

If you don't want use timer and check innerHTML you can try this event

$('mydiv').bind('DOMSubtreeModified', function(){
  console.log('changed');
});

More details and browser support datas are Here.

Attention: in newer jQuery versions bind() is deprecated, so you should use on() instead:

$('body').on('DOMSubtreeModified', 'mydiv', function(){
  console.log('changed');
});

Do you have multiple mongodb nodes in a replica set?

I found (I am using via Robomongo gui mongo shell, I guess same applies in other cases) that the correct remove syntax, i.e.

db.test_users.remove({"_id": ObjectId("4d512b45cc9374271b02ec4f")})

...does not work unless you are connected to the primary node of the replica set.

Here is an efficient solution for fast creation of a randomized array. After randomization you can simply pick the n-th element e of the array, increment n and return e. This solution has O(1) for getting a random number and O(n) for initialization, but as a tradeoff requires a good amount of memory if n gets large enough.

Apparently, your project is targeting Windows Phone 7.0. Unfortunately the constructors that accept IEnumerable<T> or List<T> are not available in WP 7.0, only the parameterless constructor. The other constructors are available in Silverlight 4 and above and WP 7.1 and above, just not in WP 7.0.

I guess your only option is to take your list and add the items into a new instance of an ObservableCollection individually as there are no readily available methods to add them in bulk. Though that's not to stop you from putting this into an extension or static method yourself.

var list = new List<SomeType> { /* ... */ };
var oc = new ObservableCollection<SomeType>();
foreach (var item in list)
    oc.Add(item);

But don't do this if you don't have to, if you're targeting framework that provides the overloads, then use them.

UPDATE FOR NEW VERSION

Glide.with(context.applicationContext)

OLD ANSWER

@outlyer's answer is correct, but there're some changes in new Glide version

My version: 4.7.1

Code:

 Glide.with(context.applicationContext)
                .asBitmap()
                .load(iconUrl)
                .into(object : SimpleTarget<Bitmap>(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL) {
                    override fun onResourceReady(resource: Bitmap, transition: com.bumptech.glide.request.transition.Transition<in Bitmap>?) {
                        callback.onReady(createMarkerIcon(resource, iconId))
                    }
                })

Note: this code run in UI Thread, thus you can use AsyncTask, Executor or somethings else for concurrency (like @outlyer's code) If you want to get original size, put Target.SIZE_ORIGINA as my code. Don't use -1, -1

iList.SelectMany(x => x).ToArray()

In python3, The way :

dict.keys() 

return a value in type : dict_keys(), we'll got an error when got 1st member of keys of dict by this way:

dict.keys()[0]
TypeError: 'dict_keys' object does not support indexing

Finally, I convert dict.keys() to list @1st, and got 1st member by list splice method:

list(dict.keys())[0]

Based on your description of what you want to do, the code seems to be correct as it is. ENDIF isn't a valid SQL loop control keyword. Are you sure that the INSERTS are actually pulling data to put into @Classes? In fact, if it was bad it just wouldn't run.

What you might want to try is to put a few PRINT statements in there. Put a PRINT above each of the INSERTS just outputting some silly text to show that that line is executing. If you get both outputs, then your SELECT...INSERT... is suspect. You could also just do the SELECT in place of the PRINT (that is, without the INSERT) and see exactly what data is being pulled.

Ternary Operator always returns a value. So in situation when you want some output value from result and there are only 2 conditions always better to use ternary operator. Use if-else if any of the above mentioned conditions are not true.

2020 solution:

I wrote a PHP function which uses the Vimeo Oembed API.

/**
 * Get Vimeo.com video thumbnail URL
 *
 * Set the referer parameter if your video is domain restricted.
 * 
 * @param  int    $videoid   Video id
 * @param  URL    $referer   Your website domain
 * @return bool/string       Thumbnail URL or false if can't access the video
 */
function get_vimeo_thumbnail_url( $videoid, $referer=null ){

    // if referer set, create context
    $ctx = null;
    if( isset($referer) ){
        $ctxa = array(
            'http' => array(
                'header' => array("Referer: $referer\r\n"),
                'request_fulluri' => true,
            ),
        );
        $ctx = stream_context_create($ctxa);
    }

    $resp = @file_get_contents("https://vimeo.com/api/oembed.json?url=https://vimeo.com/$videoid", False, $ctx);
    $resp = json_decode($resp, true);

return $resp["thumbnail_url"]??false;
}

Usage:

echo get_vimeo_thumbnail_url("1084537");

Go to the configuration file from the developer's site and paste it in the app level directory of your current project.

The Problem

RecyclerView is, by default, unaware of your dataset changes. This means that whenever you make a deletion/addition on your data list, those changes won't be reflected to your RecyclerView directly. (i.e. you remove the item at index 5, but the 6th element remains in your recycler view).

A "ok" Solution

RecyclerView exposes some methods for you to communicate your dataset changes, reflecting those changes directly on your list items. The standard Android APIs allow you to bind the process of data removal (for the purpose of the question) with the process of View removal.

The methods we talked about are:

notifyItemChanged(index: Int)
notifyItemInserted(index: Int)
notifyItemRemoved(index: Int)
notifyItemRangeChanged(startPosition: Int, itemCount: Int)
notifyItemRangeInserted(startPosition: Int, itemCount: Int)
notifyItemRangeRemoved(startPosition: Int, itemCount: Int)

Better Solution

If you don't properly specify what happens on each addition, change or removal of items, RecyclerView children are animated unresponsively because of a lack of information about how to move the different views around the list.

Instead, the following code will precisely play the animation, just on the child that is being removed (And as a side note, it fixed any IndexOutOfBoundExceptions, marked by the stacktrace as "data inconsistency").

void remove(position: Int) {
    dataset.removeAt(position)
    notifyItemChanged(position)
    notifyItemRangeRemoved(position, 1)
}

Under the hood, if we look into RecyclerView we can find documentation explaining that the second parameter we pass to notifyItemRangeRemoved is the number of items that are removed from the dataset, not the total number of items (As wrongly reported in some others information sources).

    /**
     * Notify any registered observers that the <code>itemCount</code> items previously
     * located at <code>positionStart</code> have been removed from the data set. The items
     * previously located at and after <code>positionStart + itemCount</code> may now be found
     * at <code>oldPosition - itemCount</code>.
     *
     * <p>This is a structural change event. Representations of other existing items in the data
     * set are still considered up to date and will not be rebound, though their positions
     * may be altered.</p>
     *
     * @param positionStart Previous position of the first item that was removed
     * @param itemCount Number of items removed from the data set
     */
    public final void notifyItemRangeRemoved(int positionStart, int itemCount) {
        mObservable.notifyItemRangeRemoved(positionStart, itemCount);
    }

Even Better Solution (Opinionated)

Do not use any of those functions. That's my personal view. They are counterintuitive, error-prone and they feel really verbose and unnecessary. Let a library like FastAdapter, Epoxy or Groupie take care of this business, or use an observable recycler view with data binding.

I solved my problem simply using ng-init for default selection instead of ng-checked

<div ng-init="person.billing=FALSE"></div>
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="FALSE" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="TRUE" />

The behaviour is different depending upon the database configuration. In the strict mode this would throw an error else a warning. Following query may be used for identifying the database configuration.

mysql> show variables like 'sql_mode';

Hmm.. what class is your constructor for? Probably some class extending JFrame? The window focus should be at the window, of course but I don't think that's the problem.

I expanded your code, tried to run it and it worked - the key presses resulted as print output. (run with Ubuntu through Eclipse):

public class MyFrame extends JFrame {
    public MyFrame() {
        System.out.println("test");
        addKeyListener(new KeyListener() {
            public void keyPressed(KeyEvent e) {
                System.out.println("tester");
            }

            public void keyReleased(KeyEvent e) {
                System.out.println("2test2");
            }

            public void keyTyped(KeyEvent e) {
                System.out.println("3test3");
            }
        });
    }

    public static void main(String[] args) {
        MyFrame f = new MyFrame();
        f.pack();
        f.setVisible(true);
    }
}

Wanted to ADD to the other answers described here an additional note, in the case of custom exceptions.

In the case where you create your own custom exception, that derives from std::exception, when you catch "all possible" exceptions types, you should always start the catch clauses with the "most derived" exception type that may be caught. See the example (of what NOT to do):

#include <iostream>
#include <string>

using namespace std;

class MyException : public exception
{
public:
    MyException(const string& msg) : m_msg(msg)
    {
        cout << "MyException::MyException - set m_msg to:" << m_msg << endl;
    }

   ~MyException()
   {
        cout << "MyException::~MyException" << endl;
   }

   virtual const char* what() const throw () 
   {
        cout << "MyException - what" << endl;
        return m_msg.c_str();
   }

   const string m_msg;
};

void throwDerivedException()
{
    cout << "throwDerivedException - thrown a derived exception" << endl;
    string execptionMessage("MyException thrown");
    throw (MyException(execptionMessage));
}

void illustrateDerivedExceptionCatch()
{
    cout << "illustrateDerivedExceptionsCatch - start" << endl;
    try 
    {
        throwDerivedException();
    }
    catch (const exception& e)
    {
        cout << "illustrateDerivedExceptionsCatch - caught an std::exception, e.what:" << e.what() << endl;
        // some additional code due to the fact that std::exception was thrown...
    }
    catch(const MyException& e)
    {
        cout << "illustrateDerivedExceptionsCatch - caught an MyException, e.what::" << e.what() << endl;
        // some additional code due to the fact that MyException was thrown...
    }

    cout << "illustrateDerivedExceptionsCatch - end" << endl;
}

int main(int argc, char** argv)
{
    cout << "main - start" << endl;
    illustrateDerivedExceptionCatch();
    cout << "main - end" << endl;
    return 0;
}

NOTE:

0) The proper order should be vice-versa, i.e.- first you catch (const MyException& e) which is followed by catch (const std::exception& e).

1) As you can see, when you run the program as is, the first catch clause will be executed (which is probably what you did NOT wanted in the first place).

2) Even though the type caught in the first catch clause is of type std::exception, the "proper" version of what() will be called - cause it is caught by reference (change at least the caught argument std::exception type to be by value - and you will experience the "object slicing" phenomena in action).

3) In case that the "some code due to the fact that XXX exception was thrown..." does important stuff WITH RESPECT to the exception type, there is misbehavior of your code here.

4) This is also relevant if the caught objects were "normal" object like: class Base{}; and class Derived : public Base {}...

5) g++ 7.3.0 on Ubuntu 18.04.1 produces a warning that indicates the mentioned issue:

In function ‘void illustrateDerivedExceptionCatch()’: item12Linux.cpp:48:2: warning: exception of type ‘MyException’ will be caught catch(const MyException& e) ^~~~~

item12Linux.cpp:43:2: warning: by earlier handler for ‘std::exception’ catch (const exception& e) ^~~~~

Again, I will say, that this answer is only to ADD to the other answers described here (I thought this point is worth mention, yet could not depict it within a comment).

Just for an updated answer here, there's a good js lib at http://www.datejs.com/

Datejs is an open source JavaScript Date library for parsing, formatting and processing.

SynchronizedMap and ConcurrentHashMap are both thread safe class and can be used in multithreaded application, the main difference between them is regarding how they achieve thread safety.

SynchronizedMap acquires lock on the entire Map instance , while ConcurrentHashMap divides the Map instance into multiple segments and locking is done on those.

This is how I did for my CRUDManager class initialized in Angular controller, which later passed over to jQuery button-click event defined outside the controller:

In Angular Controller:

        // Note that I can even pass over the $scope to my CRUDManager's constructor.
        var crudManager = new CRUDManager($scope, contextData, opMode);

        crudManager.initialize()
            .then(() => {
                crudManager.dataBind();
                $scope.crudManager = crudManager;
                $scope.$apply();
            })
            .catch(error => {
                alert(error);
            });

In jQuery Save button click event outside the controller:

    $(document).on("click", "#ElementWithNgControllerDefined #btnSave", function () {
        var ngScope = angular.element($("#ElementWithNgControllerDefined")).scope();
        var crudManager = ngScope.crudManager;
        crudManager.saveData()
            .then(finalData => {
               alert("Successfully saved!");
            })
            .catch(error => {
               alert("Failed to save.");
            });
    });

This is particularly important and useful when your jQuery events need to be placed OUTSIDE OF CONTROLLER in order to prevent it from firing twice.

You can use border-radius property, or make a div with fixed height and width and a background with png circle.

The following works from within the buttons click function:

$(function() {
    $("#dialog").dialog({
        height: 'auto', width: 700, modal: true,
        buttons: {
            'Add to request list': function(evt) {

                // get DOM element for button
                var buttonDomElement = evt.target;
                // Disable the button
                $(buttonDomElement).attr('disabled', true);

                $('form').submit();
            },
            'Cancel': function() {
                $(this).dialog('close');
            }
        }
    });
}

echo "text to echo" > file.txt

A generative algorithm model will learn completely from the training data and will predict the response.

A discriminative algorithm job is just to classify or differentiate between the 2 outcomes.

You can also try this.

 $(document).ready(function () {
            var url = "@(Html.Raw(Url.Action("ActionName", "ControllerName")))";
            $("#PartialViewDivId").load(url);
        setInterval(function () {
            var url = "@(Html.Raw(Url.Action("ActionName", "ControllerName")))";
            $("#PartialViewDivId").load(url);
        }, 30000); //Refreshes every 30 seconds

        $.ajaxSetup({ cache: false });  //Turn off caching
    });

It makes an initial call to load the div, and then subsequent calls are on a 30 second interval.

In the controller section you can update the object and pass the object to the partial view.

public class ControllerName: Controller
{
    public ActionResult ActionName()
    {
        .
        .   // code for update object
        .
        return PartialView("PartialViewName", updatedObject);
    }
}

Postgres started on Linux/Unix. I suspect that reversing the slash with fix it.

\i somedir/script2.sql 

If you need to fully qualify something

\i c:/somedir/script2.sql

If that doesn't fix it, my next guess would be you need to escape the backslash.

\i somedir\\script2.sql
