As the documentation says you can just use an URL like:

https://wa.me/15551234567

Where the last segment is the number in in E164 Format

Uri uri = Uri.parse("https://wa.me/15551234567");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

The page to do this is at https://developers.facebook.com/tools/debug/ and has changed slightly since some of the other answers.

Paste your URL in there and hit "Debug". Then hit the "Fetch new scrape information" button under the URL text field and you should be all set. It'll pull the fresh meta tags from your page, but they'll still cache so keep in mind you'll need to do this whenever you change them. This is really critical if you are playing with the meta tags to get FB Shared URLs to format the way you want them to inside of facebook.

I understand that you asked that you would like a CSS specific solution. To keep the aspect ratio, you would need to divide the height by the desired aspect ratio. 16:9 = 1.777777777778.

To get the correct height for the container, you would need to divide the current width by 1.777777777778. Since you can't check the width of the container with just CSS or divide by a percentage is CSS, this is not possible without JavaScript (to my knowledge).

I've written a working script that will keep the desired aspect ratio.

HTML

<div id="aspectRatio"></div>

CSS

body { width: 100%; height: 100%; padding: 0; margin: 0; }
#aspectRatio { background: #ff6a00; }

JavaScript

window.onload = function () {
    //Let's create a function that will scale an element with the desired ratio
    //Specify the element id, desired width, and height
    function keepAspectRatio(id, width, height) {
        var aspectRatioDiv = document.getElementById(id);
        aspectRatioDiv.style.width = window.innerWidth;
        aspectRatioDiv.style.height = (window.innerWidth / (width / height)) + "px";
    }

    //run the function when the window loads
    keepAspectRatio("aspectRatio", 16, 9);

    //run the function every time the window is resized
    window.onresize = function (event) {
        keepAspectRatio("aspectRatio", 16, 9);
    }
}

You can use the function again if you'd like to display something else with a different ratio by using

keepAspectRatio(id, width, height);

In addition to using Request.Form and Request.QueryString and depending on your specific scenario, it may also be useful to check the Page's IsPostBack property.

if (Page.IsPostBack)
{
  // HTTP Post
}
else
{
  // HTTP Get
}

Extracting the title is not difficult, and you have many options, search here on Stack Overflow for "Java HTML parsers". One of them is Jsoup.

You can navigate the page using DOM if you know the page structure, see http://jsoup.org/cookbook/extracting-data/dom-navigation

It's a good library and I've used it in my last projects.

If you don't have bs-config.json, you can change the port inside the lite-server module. Go to node_modules/lite-server/lib/config-defaults.js in your project, then add the port in "modules.export" like this.

module.export {
    port :8000, // to any available port
    ...
}

Then you can restart the server.

It's too late to answer this question now, but hope this helps someone.

@Eimantas has already given the best answer but the solution won't work if you have two or more tables by the same name under the same server.

I have slightly modified @Eimantas's answer to tackle the above problem.

select Auto_increment as id from information_schema.tables where table_name = 'table_name' and table_schema = 'database_name'

Just simply use r'string'. Hope this will help you as I see you haven't got your expected answer yet:

    test = 'C:\\Windows\Users\alexb\'
    rawtest = r'%s' %test

The options are the same as for the fopen function in the C standard library:

w truncates the file, overwriting whatever was already there

a appends to the file, adding onto whatever was already there

w+ opens for reading and writing, truncating the file but also allowing you to read back what's been written to the file

a+ opens for appending and reading, allowing you both to append to the file and also read its contents

Like the answer above but here is using bootstrap 3 names and colours:

/*css to add back colours for badges and make use of the colours*/_x000D_
.badge-default {_x000D_
  background-color: #999999;_x000D_
}_x000D_
_x000D_
.badge-primary {_x000D_
  background-color: #428bca;_x000D_
}_x000D_
_x000D_
.badge-success {_x000D_
  background-color: #5cb85c;_x000D_
}_x000D_
_x000D_
.badge-info {_x000D_
  background-color: #5bc0de;_x000D_
}_x000D_
_x000D_
.badge-warning {_x000D_
  background-color: #f0ad4e;_x000D_
}_x000D_
_x000D_
.badge-danger {_x000D_
  background-color: #d9534f;_x000D_
}

You can use a subquery. The subquery will get the Max(CompletedDate). You then take this value and join on your table again to retrieve the note associate with that date:

select ET1.TrainingID,
  ET1.CompletedDate,
  ET1.Notes
from HR_EmployeeTrainings ET1
inner join
(
  select Max(CompletedDate) CompletedDate, TrainingID
  from HR_EmployeeTrainings
  --where AvantiRecID IS NULL OR AvantiRecID = @avantiRecID
  group by TrainingID
) ET2
  on ET1.TrainingID = ET2.TrainingID
  and ET1.CompletedDate = ET2.CompletedDate
where ET1.AvantiRecID IS NULL OR ET1.AvantiRecID = @avantiRecID

It works for me when I set the delegate

self.navigationController.interactivePopGestureRecognizer.delegate = self;

and then implement

Swift

extension MyViewController:UIGestureRecognizerDelegate {
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldBeRequiredToFailBy otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }
}

Objective-C

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

here we console natural number 0 to ......n (next number print in console every 60 sec.) , using setInterval()

var count = 0;
function abc(){
    count ++;
    console.log(count);
}
setInterval(abc,60*1000);

By pressing one arrow key getch will push three values into the buffer:

• '\033'
• '['
• 'A', 'B', 'C' or 'D'

So the code will be something like this:

if (getch() == '\033') { // if the first value is esc
    getch(); // skip the [
    switch(getch()) { // the real value
        case 'A':
            // code for arrow up
            break;
        case 'B':
            // code for arrow down
            break;
        case 'C':
            // code for arrow right
            break;
        case 'D':
            // code for arrow left
            break;
    }
}

how about in vuejs how is it applicable?

  var pdf = new jsPDF('p', 'pt', 'letter');_x000D_

I was experiencing this same symptom - 404 on woff files in Chrome - and was running an application on a Windows Server with IIS 6.

If you are in the same situation you can fix it by doing the following:

Solution 1

"Simply add the following MIME type declarations via IIS Manager (HTTP Headers tab of website properties): .woff application/x-woff"

Update: according to MIME Types for woff fonts and Grsmto the actual MIME type is application/x-font-woff (for Chrome at least). x-woff will fix Chrome 404s, x-font-woff will fix Chrome warnings.

As of 2017: Woff fonts have now been standardised as part of the RFC8081 specification to the mime type font/woff and font/woff2.

Thanks to Seb Duggan: http://sebduggan.com/posts/serving-web-fonts-from-iis

Solution 2

You can also add the MIME types in the web config:

  <system.webServer>
    <staticContent>
      <remove fileExtension=".woff" /> <!-- In case IIS already has this mime type -->
      <mimeMap fileExtension=".woff" mimeType="font/woff" />
    </staticContent>    
  </system.webServer>

You don't really need to install or use any third party tools.

The drivers located in ...\Android\Sdk\extras\google\usb_driver work just fine.

Step 1: In Device Manager, Right click on the malfunctioning Android ADB Interface driver

Step 2: Select Update Driver Software

Step 3: Select Browse my computer for driver software

Step 4: Select Let me pick from a list of device drivers on my computer

Step 5: Select Have Disk

This window pops up:

Step 6: Copy the location of the Google USB Driver (...\Android\Sdk\extras\google\usb_driver) or browse to it.

Step 7: Click Ok

This window pops up:

Step 8: Select Android ADB Interface and click Next

The window below pops up with a warning:

That's it. You driver installation will start and in a few seconds, you should be able to see your device

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:

    bar <- foo[foo[ ,1] == "there", ]

This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).

This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:

    foo[foo[ ,c(1:N)], ]

Or specific columns, as you would expect.

    foo[foo[ ,c(1,5,9)], ]

I used tuples to do that, this is an example for two columns :

 var list= list1.Join(list2,
                       e1 => (e1.val1,e1.val2),
                       e2 => (e2.val1,e2.val2),
                       (e1, e2) => e1).ToList();

Old post, but I thought I'd weigh in, with a DataTable extension that can convert a single column at a time, to a given type:

public static class DataTableExt
{
    public static void ConvertColumnType(this DataTable dt, string columnName, Type newType)
    {
        using (DataColumn dc = new DataColumn(columnName + "_new", newType))
        {
            // Add the new column which has the new type, and move it to the ordinal of the old column
            int ordinal = dt.Columns[columnName].Ordinal;
            dt.Columns.Add(dc);
            dc.SetOrdinal(ordinal);

            // Get and convert the values of the old column, and insert them into the new
            foreach (DataRow dr in dt.Rows)
                dr[dc.ColumnName] = Convert.ChangeType(dr[columnName], newType);

            // Remove the old column
            dt.Columns.Remove(columnName);

            // Give the new column the old column's name
            dc.ColumnName = columnName;
        }
    }
}

It can then be called like this:

MyTable.ConvertColumnType("MyColumnName", typeof(int));

Of course using whatever type you desire, as long as each value in the column can actually be converted to the new type.

Heuristic, in a nutshell is an "Educated guess". Wikipedia explains it nicely. At the end, a "general acceptance" method is taken as an optimal solution to the specified problem.

Heuristic is an adjective for experience-based techniques that help in problem solving, learning and discovery. A heuristic method is used to rapidly come to a solution that is hoped to be close to the best possible answer, or 'optimal solution'. Heuristics are "rules of thumb", educated guesses, intuitive judgments or simply common sense. A heuristic is a general way of solving a problem. Heuristics as a noun is another name for heuristic methods.

In more precise terms, heuristics stand for strategies using readily accessible, though loosely applicable, information to control problem solving in human beings and machines.

While an algorithm is a method containing finite set of instructions used to solving a problem. The method has been proven mathematically or scientifically to work for the problem. There are formal methods and proofs.

Heuristic algorithm is an algorithm that is able to produce an acceptable solution to a problem in many practical scenarios, in the fashion of a general heuristic, but for which there is no formal proof of its correctness.

You only initialize the first N positions to the values in braces and all others are initialized to 0. In this case, N is the number of arguments you passed to the initialization list, i.e.,

float arr1[10] = { };       // all elements are 0
float arr2[10] = { 0 };     // all elements are 0
float arr3[10] = { 1 };     // first element is 1, all others are 0
float arr4[10] = { 1, 2 };  // first element is 1, second is 2, all others are 0

var Text = File.ReadAllLines("Path"); foreach (var i in Text) {    var SplitText = i.Split().Where(x=> x.Lenght>1).ToList();    //@Array1 add SplitText[0]    //@Array2 add SpliteText[1]   }  

HashMap that also works with keys other than strings and integers with O(1) read complexity (depending on quality of your own hash-function).

You can make a simple hashMap yourself. What a hashMap does is storing items in a array using the hash as index/key. Hash-functions give collisions once in a while (not often, but they may do), so you have to store multiple items for an entry in the hashMap. That simple is a hashMap:

class IEqualityComparer {
    public function equals($x, $y) {
        throw new Exception("Not implemented!");
    }
    public function getHashCode($obj) {
        throw new Exception("Not implemented!");
    }
}

class HashMap {
    private $map = array();
    private $comparer;

    public function __construct(IEqualityComparer $keyComparer) {
        $this->comparer = $keyComparer;
    }

    public function has($key) {
        $hash = $this->comparer->getHashCode($key);

        if (!isset($this->map[$hash])) {
            return false;
        }

        foreach ($this->map[$hash] as $item) {
            if ($this->comparer->equals($item['key'], $key)) {
                return true;
            }
        }

        return false;
    }

    public function get($key) {
        $hash = $this->comparer->getHashCode($key);

        if (!isset($this->map[$hash])) {
            return false;
        }

        foreach ($this->map[$hash] as $item) {
            if ($this->comparer->equals($item['key'], $key)) {
                return $item['value'];
            }
        }

        return false;
    }

    public function del($key) {
        $hash = $this->comparer->getHashCode($key);

        if (!isset($this->map[$hash])) {
            return false;
        }

        foreach ($this->map[$hash] as $index => $item) {
            if ($this->comparer->equals($item['key'], $key)) {
                unset($this->map[$hash][$index]);
                if (count($this->map[$hash]) == 0)
                    unset($this->map[$hash]);

                return true;
            }
        }

        return false;
    }

    public function put($key, $value) {
        $hash = $this->comparer->getHashCode($key);

        if (!isset($this->map[$hash])) {
            $this->map[$hash] = array();
        }

        $newItem = array('key' => $key, 'value' => $value);        

        foreach ($this->map[$hash] as $index => $item) {
            if ($this->comparer->equals($item['key'], $key)) {
                $this->map[$hash][$index] = $newItem;
                return;
            }
        }

        $this->map[$hash][] = $newItem;
    }
}

For it to function you also need a hash-function for your key and a comparer for equality (if you only have a few items or for another reason don't need speed you can let the hash-function return 0; all items will be put in same bucket and you will get O(N) complexity)

Here is an example:

class IntArrayComparer extends IEqualityComparer {
    public function equals($x, $y) {
        if (count($x) !== count($y))
            return false;

        foreach ($x as $key => $value) {
            if (!isset($y[$key]) || $y[$key] !== $value)
                return false;
        }

        return true;
    }

    public function getHashCode($obj) {
        $hash = 0;
        foreach ($obj as $key => $value)
            $hash ^= $key ^ $value;

        return $hash;
    }
}

$hashmap = new HashMap(new IntArrayComparer());

for ($i = 0; $i < 10; $i++) {
    for ($j = 0; $j < 10; $j++) {
        $hashmap->put(array($i, $j), $i * 10 + $j);
    }
}

echo $hashmap->get(array(3, 7)) . "<br/>";
echo $hashmap->get(array(5, 1)) . "<br/>";

echo ($hashmap->has(array(8, 4))? 'true': 'false') . "<br/>";
echo ($hashmap->has(array(-1, 9))? 'true': 'false') . "<br/>";
echo ($hashmap->has(array(6))? 'true': 'false') . "<br/>";
echo ($hashmap->has(array(1, 2, 3))? 'true': 'false') . "<br/>";

$hashmap->del(array(8, 4));
echo ($hashmap->has(array(8, 4))? 'true': 'false') . "<br/>";

Which gives as output:

37
51
true
false
false
false
false

Easy solution if you don't want to code manually using Google Sheets Power Tools:

1. Install Power Tools through the Add-ons panel (Add-ons -> Get add-ons)
2. From the Power Tools sidebar click on the S button and within that menu click on the "Sum by Color" menu item
3. Select the "Pattern cell" with the color markup you want to search for
4. Select the "Source range" for the cells you want to count
5. Use function should be set to "COUNTA"
6. Press "Insert function" and you're done :)

Another Solution : you get the marker by its title

public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity implements OnMarkerClickListener
{
      private Marker myMarker;    

      private void setUpMap()
      {
      .......
      googleMap.setOnMarkerClickListener(this);

      myMarker = googleMap.addMarker(new MarkerOptions()
                  .position(latLng)
                  .title("My Spot")
                  .snippet("This is my spot!")
                  .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
      ......
      }

  @Override
  public boolean onMarkerClick(final Marker marker) 
  {

     String name= marker.getTitle();

      if (name.equalsIgnoreCase("My Spot")) 
      {
          //write your code here
      }
  }
}

Building on the accepted answer, if you want the file to be checked for permissions on every run, and these changed accordingly if the file exists, or just create the file if it doesn't exist, you can use the following:

- stat: path=/etc/nologin
  register: p

- name: create fake 'nologin' shell
  file: path=/etc/nologin 
        owner=root
        group=sys
        mode=0555
        state={{ "file" if  p.stat.exists else "touch"}}

I have tested all of this examples, I did a benchmark, and finally I recommend you choose the shorter one, it doesn't affect in performance.

Here's a couple of pure css helper classes which lets you handle any kind of toggle content right in your html.

It works with any element you need to switch. Whatever your layout is you just put it inside a couple of elements with the .if-collapsed and .if-not-collapsed classes within the toggle element.

The only catch is that you have to make sure you put the desired initial state of the toggle. If it's initially closed, then put a collapsed class on the toggle.

It also requires the :not selector, it doesn't work on IE8.

HTML example:

<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
  <!--You can put any valid html inside these!-->
  <span class="if-collapsed">Open</span>
  <span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

Less version:

[data-toggle="collapse"] {
    &.collapsed .if-not-collapsed {
         display: none;
    }
    &:not(.collapsed) .if-collapsed {
         display: none;
    }
}

CSS version:

[data-toggle="collapse"].collapsed .if-not-collapsed {
  display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
  display: none;
}

Thanks to a related question, I found out that I need to "checkout" the remote branch as a new local branch, and specify a new local branch name.

git checkout -b newlocalbranchname origin/branch-name

Or you can do:

git checkout -t origin/branch-name

The latter will create a branch that is also set to track the remote branch.

Update: It's been 5 years since I originally posted this question. I've learned a lot and git has improved since then. My usual workflow is a little different now.

If I want to fetch the remote branches, I simply run:

git pull

This will fetch all of the remote branches and merge the current branch. It will display an output that looks something like this:

From github.com:andrewhavens/example-project
   dbd07ad..4316d29  master     -> origin/master
 * [new branch]      production -> origin/production
 * [new branch]      my-bugfix-branch -> origin/my-bugfix-branch
First, rewinding head to replay your work on top of it...
Fast-forwarded master to 4316d296c55ac2e13992a22161fc327944bcf5b8.

Now git knows about my new my-bugfix-branch. To switch to this branch, I can simply run:

git checkout my-bugfix-branch

Normally, I would need to create the branch before I could check it out, but in newer versions of git, it's smart enough to know that you want to checkout a local copy of this remote branch.

@tommasop's answer is good, and explains some of the mechanics of using data-only containers. But as someone who initially thought that data containers were silly when one could just bind mount a volume to the host (as suggested by several other answers), but now realizes that in fact data-only containers are pretty neat, I can suggest my own blog post on this topic: Why Docker Data Containers (Volumes!) are Good

See also: my answer to the question "What is the (best) way to manage permissions for Docker shared volumes?" for an example of how to use data containers to avoid problems like permissions and uid/gid mapping with the host.

To address one of the OP's original concerns: that the data container must not be deleted. Even if the data container is deleted, the data itself will not be lost as long as any container has a reference to that volume i.e. any container that mounted the volume via --volumes-from. So unless all the related containers are stopped and deleted (one could consider this the equivalent of an accidental rm -fr /) the data is safe. You can always recreate the data container by doing --volumes-from any container that has a reference to that volume.

As always, make backups though!

UPDATE: Docker now has volumes that can be managed independently of containers, which further makes this easier to manage.

Note: This answer is really old and things may have changed in WordPress land since.

I am guessing that you need to detect the WordPress root from your plugin or theme. I use the following code in FireStats to detect the root WordPress directory where FireStats is installed a a WordPress plugin.

function fs_get_wp_config_path()
{
    $base = dirname(__FILE__);
    $path = false;

    if (@file_exists(dirname(dirname($base))."/wp-config.php"))
    {
        $path = dirname(dirname($base))."/wp-config.php";
    }
    else
    if (@file_exists(dirname(dirname(dirname($base)))."/wp-config.php"))
    {
        $path = dirname(dirname(dirname($base)))."/wp-config.php";
    }
    else
        $path = false;

    if ($path != false)
    {
        $path = str_replace("\\", "/", $path);
    }
    return $path;
}

Use sum() in place of count()

Try below:

SELECT
    ccc_news . * , 
    SUM(if(ccc_news_comments.id = 'approved', 1, 0)) AS comments
FROM
    ccc_news
    LEFT JOIN
        ccc_news_comments
    ON
        ccc_news_comments.news_id = ccc_news.news_id
WHERE
    `ccc_news`.`category` = 'news_layer2'
    AND `ccc_news`.`status` = 'Active'
GROUP BY
    ccc_news.news_id
ORDER BY
    ccc_news.set_order ASC
LIMIT 20 

I know this thread is a little old but it came in handy for a specific scenario I had and I thought it worth while to note that there is another reason why System.Threading.Timer might be a good approach. When you have to periodically execute a Job that might take a long time and you want to ensure that the entire waiting period is used between jobs or if you don't want the job to run again before the previous job has finished in the case where the job takes longer than the timer period. You could use the following:

using System;
using System.ServiceProcess;
using System.Threading;

    public partial class TimerExampleService : ServiceBase
    {
        private AutoResetEvent AutoEventInstance { get; set; }
        private StatusChecker StatusCheckerInstance { get; set; }
        private Timer StateTimer { get; set; }
        public int TimerInterval { get; set; }

        public CaseIndexingService()
        {
            InitializeComponent();
            TimerInterval = 300000;
        }

        protected override void OnStart(string[] args)
        {
            AutoEventInstance = new AutoResetEvent(false);
            StatusCheckerInstance = new StatusChecker();

            // Create the delegate that invokes methods for the timer.
            TimerCallback timerDelegate =
                new TimerCallback(StatusCheckerInstance.CheckStatus);

            // Create a timer that signals the delegate to invoke 
            // 1.CheckStatus immediately, 
            // 2.Wait until the job is finished,
            // 3.then wait 5 minutes before executing again. 
            // 4.Repeat from point 2.
            Console.WriteLine("{0} Creating timer.\n",
                DateTime.Now.ToString("h:mm:ss.fff"));
            //Start Immediately but don't run again.
            StateTimer = new Timer(timerDelegate, AutoEventInstance, 0, Timeout.Infinite);
            while (StateTimer != null)
            {
                //Wait until the job is done
                AutoEventInstance.WaitOne();
                //Wait for 5 minutes before starting the job again.
                StateTimer.Change(TimerInterval, Timeout.Infinite);
            }
            //If the Job somehow takes longer than 5 minutes to complete then it wont matter because we will always wait another 5 minutes before running again.
        }

        protected override void OnStop()
        {
            StateTimer.Dispose();
        }
    }

    class StatusChecker
        {

            public StatusChecker()
            {
            }

            // This method is called by the timer delegate.
            public void CheckStatus(Object stateInfo)
            {
                AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
                Console.WriteLine("{0} Start Checking status.",
                    DateTime.Now.ToString("h:mm:ss.fff"));
                //This job takes time to run. For example purposes, I put a delay in here.
                int milliseconds = 5000;
                Thread.Sleep(milliseconds);
                //Job is now done running and the timer can now be reset to wait for the next interval
                Console.WriteLine("{0} Done Checking status.",
                    DateTime.Now.ToString("h:mm:ss.fff"));
                autoEvent.Set();
            }
        }

You will need to know something about the URLs, like do they have a specific directory or some query string element because you have to match for something. Otherwise you will have to redirect on the 404. If this is what is required then do something like this in your .htaccess:

ErrorDocument 404 /index.php

An error page redirect must be relative to root so you cannot use www.mydomain.com.

If you have a pattern to match too then use 301 instead of 302 because 301 is permanent and 302 is temporary. A 301 will get the old URLs removed from the search engines and the 302 will not.

To expand on Ryan's answer:

Whenever setStateValues is called, React re-renders your component, which means that the function body of the StateSelector component function gets re-executed.

React docs:

setState() will always lead to a re-render unless shouldComponentUpdate() returns false.

Essentially, you're setting state with:

setStateValues(allowedState);

causing a re-render, which then causes the function to execute, and so on. Hence, the loop issue.

To illustrate the point, if you set a timeout as like:

  setTimeout(
    () => setStateValues(allowedState),
    1000
  )

Which ends the 'too many re-renders' issue.

In your case, you're dealing with a side-effect, which is handled with UseEffectin your component functions. You can read more about it here.

Try using:

body {
  background-attachment: fixed;
  background-image: url(./Images/bg4.jpg);
}

Images being folder holding the picture that you want to post.

With ES6: This is now part of the language:

function myFunc(a, b = 0) {
   // function body
}

Please keep in mind that ES6 checks the values against undefined and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).

With ES5:

function myFunc(a,b) {
  b = b || 0;

  // b will be set either to b or to 0.
}

This works as long as all values you explicitly pass in are truthy. Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''

It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.

If you need to get quantity of selected checkboxes:

var selected = []; // initialize array
    $('div#checkboxes input[type=checkbox]').each(function() {
       if ($(this).is(":checked")) {
           selected.push($(this));
       }
    });
var selectedQuantity = selected.length;

The issue is with the facebook cache and solution is to refresh the facebook cache by going to the link. https://developers.facebook.com/tools/debug/og/object/

and pressing the button "Fetch New Scrape information".

Hope it helps

JavaScript has Maps, that provide O(1) insertion and lookup time. Therefore this can be solved in O(n) (and not O(n²) as all the other answers do). For that, it is necessary to generate a unique primitive (string / number) key for each object. One could JSON.stringify, but that's quite error prone as the order of elements could influence equality:

 JSON.stringify({ a: 1, b: 2 }) !== JSON.stringify({ b: 2, a: 1 })

Therefore, I'd take a delimiter that does not appear in any of the values and compose a string manually:

const toHash = value => value.value + "@" + value.display;

Then a Map gets created. When an element exists already in the Map, it gets removed, otherwise it gets added. Therefore only the elements that are included odd times (meaning only once) remain. This will only work if the elements are unique in each array:

const entries = new Map();

for(const el of [...firstArray, ...secondArray]) {
  const key = toHash(el);
  if(entries.has(key)) {
    entries.delete(key);
  } else {
    entries.set(key, el);
  }
}

const result = [...entries.values()];

const firstArray = [_x000D_
    { value: "0", display: "Jamsheer" },_x000D_
    { value: "1", display: "Muhammed" },_x000D_
    { value: "2", display: "Ravi" },_x000D_
    { value: "3", display: "Ajmal" },_x000D_
    { value: "4", display: "Ryan" }_x000D_
]_x000D_
_x000D_
const secondArray = [_x000D_
    { value: "0", display: "Jamsheer" },_x000D_
    { value: "1", display: "Muhammed" },_x000D_
    { value: "2", display: "Ravi" },_x000D_

Speaking for current (2021-2) Java versions there is still the old ISO-8859-1 function utils.Properties#load.

• If you use Properties.load you must use ISO-8859-1.
• If you use ResourceBundle than UTF-8 should be fine.

Allow me to quote from the official doc.

PropertyResourceBundle

PropertyResourceBundle can be constructed either from an InputStream or a Reader, which represents a property file. Constructing a PropertyResourceBundle instance from an InputStream requires that the input stream be encoded in UTF-8. By default, if a MalformedInputException or an UnmappableCharacterException occurs on reading the input stream, then the PropertyResourceBundle instance resets to the state before the exception, re-reads the input stream in ISO-8859-1, and continues reading. If the system property java.util.PropertyResourceBundle.encoding is set to either "ISO-8859-1" or "UTF-8", the input stream is solely read in that encoding, and throws the exception if it encounters an invalid sequence. If "ISO-8859-1" is specified, characters that cannot be represented in ISO-8859-1 encoding must be represented by Unicode Escapes as defined in section 3.3 of The Java™ Language Specification whereas the other constructor which takes a Reader does not have that limitation. Other encoding values are ignored for this system property. The system property is read and evaluated when initializing this class. Changing or removing the property has no effect after the initialization.

https://docs.oracle.com/en/java/javase/14/docs/api/java.base/java/util/PropertyResourceBundle.html

Properties#load

Reads a property list (key and element pairs) from the input byte stream. The input stream is in a simple line-oriented format as specified in load(Reader) and is assumed to use the ISO 8859-1 character encoding; that is each byte is one Latin1 character. Characters not in Latin1, and certain special characters, are represented in keys and elements using Unicode escapes as defined in section 3.3 of The Java™ Language Specification.

https://docs.oracle.com/en/java/javase/14/docs/api/java.base/java/util/Properties.html#load(java.io.InputStream)

You can try with following command:

sudo service mongod start

I've fixed this…by simply opening a new tab.

Why it wasn't working I'm not entirely sure, but it could have something to do with how Chrome deals with multiple downloads on a page, perhaps it thought they were spam and just ignored them.

1. Create a .gitignore file, so to do that, you just create any blank .txt file.

2. Then you have to change its name writing the following line on the cmd (where git.txt is the name of the file you've just created):

   rename git.txt .gitignore

3. Then you can open the file and write all the untracked files you want to ignore for good. For example, mine looks like this:

```

OS junk files
[Tt]humbs.db
*.DS_Store

#Visual Studio files
*.[Oo]bj
*.user
*.aps
*.pch
*.vspscc
*.vssscc
*_i.c
*_p.c
*.ncb
*.suo
*.tlb
*.tlh
*.bak
*.[Cc]ache
*.ilk
*.log
*.lib
*.sbr
*.sdf
*.pyc
*.xml
ipch/
obj/
[Bb]in
[Dd]ebug*/
[Rr]elease*/
Ankh.NoLoad

#Tooling
_ReSharper*/
*.resharper
[Tt]est[Rr]esult*

#Project files
[Bb]uild/

#Subversion files
.svn

# Office Temp Files
~$*

There's a whole collection of useful .gitignore files by GitHub

4. Once you have this, you need to add it to your git repository just like any other file, only it has to be in the root of the repository.

5. Then in your terminal you have to write the following line:

   git config --global core.excludesfile ~/.gitignore_global

From oficial doc:

You can also create a global .gitignore file, which is a list of rules for ignoring files in every Git repository on your computer. For example, you might create the file at ~/.gitignore_global and add some rules to it.

Open Terminal. Run the following command in your terminal: git config --global core.excludesfile ~/.gitignore_global

If the respository already exists then you have to run these commands:

git rm -r --cached .
git add .
git commit -m ".gitignore is now working"

If the step 2 doesn´t work then you should write the hole route of the files that you would like to add.

You are removing the item during a foreach, yes? Simply, you can't. There are a few common options here:

• use List<T> and RemoveAll with a predicate

• iterate backwards by index, removing matching items

  for(int i = list.Count - 1; i >= 0; i--) {
      if({some test}) list.RemoveAt(i);
  }
  

• use foreach, and put matching items into a second list; now enumerate the second list and remove those items from the first (if you see what I mean)

Modify your WHERE condition like this:

WHERE mycolumn LIKE '%\_%' ESCAPE '\'

This is one of the ways in which Oracle supports escape characters. Here you define the escape character with the escape keyword. For details see this link on Oracle Docs.

The '_' and '%' are wildcards in a LIKE operated statement in SQL.

The _ character looks for a presence of (any) one single character. If you search by columnName LIKE '_abc', it will give you result with rows having 'aabc', 'xabc', '1abc', '#abc' but NOT 'abc', 'abcc', 'xabcd' and so on.

The '%' character is used for matching 0 or more number of characters. That means, if you search by columnName LIKE '%abc', it will give you result with having 'abc', 'aabc', 'xyzabc' and so on, but no 'xyzabcd', 'xabcdd' and any other string that does not end with 'abc'.

In your case you have searched by '%_%'. This will give all the rows with that column having one or more characters, that means any characters, as its value. This is why you are getting all the rows even though there is no _ in your column values.

I would recommend using Git Graph extension.

you can just use post to post your json.

values := map[string]string{"username": username, "password": password}

jsonValue, _ := json.Marshal(values)

resp, err := http.Post(authAuthenticatorUrl, "application/json", bytes.NewBuffer(jsonValue))

This is the jQuery method. Looks like overkill but it calculates the offset.

I made the following little scss mixin to build for all the bootstrap breakpoints...

With it I get .col-xs-divider-left or col-lg-divider-right etc.

Note: this uses v4-alpha bootstrap syntax...

@import 'variables';

$divider-height: 100%;

@mixin make-column-dividers($breakpoints: $grid-breakpoints) {
    // Common properties for all breakpoints
    %col-divider {
        position: absolute;
        content: " ";
        top: (100% - $divider-height)/2;
        height: $divider-height;
        width: $hr-border-width;
        background-color: $hr-border-color;
    }
    @each $breakpoint in map-keys($breakpoints) {

    }

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

You're trying to return variable Labels of type ArtworkData instead of array, therefore this needs to be in the method signature as its return type. You need to modify your code as such:

public static ArtworkData[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels;
}

Array[] is actually an array of Array, if that makes sense.

If your computer is a 64bit, all you need to do is uninstall your Java x86 version and install a 64bit version. I had the same problem and this worked. Nothing further needs to be done.

$('#submit').click(function(){
   if($('#myMessage').val() == ''){
      alert('Input can not be left blank');
   }
});

Update

If you don't want whitespace also u can remove them using jQuery.trim()

Description: Remove the whitespace from the beginning and end of a string.

$('#submit').click(function(){
   if($.trim($('#myMessage').val()) == ''){
      alert('Input can not be left blank');
   }
});

The first time you click the link, the openSolution function is executed. That function binds the click event handler to the link, but it won't execute it. The second time you click the link, the click event handler will be executed.

What you are doing seems to kind of defeat the point of using jQuery in the first place. Why not just bind the click event to the elements in the first place:

$(document).ready(function() {
    $("#solTitle a").click(function() {
        //Do stuff when clicked
    });
});

This way you don't need onClick attributes on your elements.

It also looks like you have multiple elements with the same id value ("solTitle"), which is invalid. You would need to find some other common characteristic (class is usually a good option). If you change all occurrences of id="solTitle" to class="solTitle", you can then use a class selector:

$(".solTitle a")

Since duplicate id values is invalid, the code will not work as expected when facing multiple copies of the same id. What tends to happen is that the first occurrence of the element with that id is used, and all others are ignored.

window.alert = null;
alert('test'); // fail
delete window.alert; // true
alert('test'); // win

window is an instance of DOMWindow, and by setting something to window.alert, the correct implementation is being "shadowed", i.e. when accessing alert it is first looking for it on the window object. Usually this is not found, and it then goes up the prototype chain to find the native implementation. However, when manually adding the alert property to window it finds it straight away and does not need to go up the prototype chain. Using delete window.alert you can remove the window own property and again expose the prototype implementation of alert. This may help explain:

window.hasOwnProperty('alert'); // false
window.alert = null;
window.hasOwnProperty('alert'); // true
delete window.alert;
window.hasOwnProperty('alert'); // false

I'm following the spec here and I'm not sure whether it allows onFulfilled to be called with multiple arguments.

Nope, just the first parameter will be treated as resolution value in the promise constructor. You can resolve with a composite value like an object or array.

I don't care about how any specific promises implementation does it, I wish to follow the w3c spec for promises closely.

That's where I believe you're wrong. The specification is designed to be minimal and is built for interoperating between promise libraries. The idea is to have a subset which DOM futures for example can reliably use and libraries can consume. Promise implementations do what you ask with .spread for a while now. For example:

Promise.try(function(){
    return ["Hello","World","!"];
}).spread(function(a,b,c){
    console.log(a,b+c); // "Hello World!";
});

With Bluebird. One solution if you want this functionality is to polyfill it.

if (!Promise.prototype.spread) {
    Promise.prototype.spread = function (fn) {
        return this.then(function (args) {
            return Promise.all(args); // wait for all
        }).then(function(args){
         //this is always undefined in A+ complaint, but just in case
            return fn.apply(this, args); 
        });
    };
}

This lets you do:

Promise.resolve(null).then(function(){
    return ["Hello","World","!"]; 
}).spread(function(a,b,c){
    console.log(a,b+c);    
});

With native promises at ease fiddle. Or use spread which is now (2018) commonplace in browsers:

Promise.resolve(["Hello","World","!"]).then(([a,b,c]) => {
  console.log(a,b+c);    
});

Or with await:

let [a, b, c] = await Promise.resolve(['hello', 'world', '!']);

A Pythonic way to find the index of the maximum list element would be

position = max(enumerate(a), key=lambda x: x[1])[0]

Which does one pass. Yet, it is slower than the solution by @Silent_Ghost and, even more so, @nmichaels:

for i in s m j n; do echo $i;  python -mtimeit -s"import maxelements as me" "me.maxelements_${i}(me.a)"; done
s
100000 loops, best of 3: 3.13 usec per loop
m
100000 loops, best of 3: 4.99 usec per loop
j
100000 loops, best of 3: 3.71 usec per loop
n
1000000 loops, best of 3: 1.31 usec per loop

For those still getting this error, adding encode("utf-8") to soup will also fix this.

soup = BeautifulSoup(html_doc, 'html.parser').encode("utf-8")

Most of annotations in both versions are same, but few differs.

Reference

Order of Execution.

Dashed box -> optional annotation.

Open npm command prompt and -- cd solution folder and then just run npm link webpack in NPM cmd prommt and re build..

There is many way to do this.

1. Using MediaQuery : Its return fullscreen of your device including appbar,toolbar

 Container(
        width: MediaQuery.of(context).size.width * 0.50,
        height: MediaQuery.of(context).size.height*0.50, 
        color: Colors.blueAccent[400],
 )

2. Using Expanded : You can set width/height in ratio

 Container(
        height: MediaQuery.of(context).size.height * 0.50,
        child: Row(
          children: <Widget>[
            Expanded(
              flex: 70,
              child: Container(
                color: Colors.lightBlue[400],
              ),
            ),
            Expanded(
              flex: 30,
              child: Container(
                color: Colors.deepPurple[800],
              ),
            )
          ],
        ),
    )

3. Others Like Flexible and AspectRatio and FractionallySizedBox

Given that commonly 1 = true and 0 = false, all you need to do is count the number of rows, and cast to a boolean.

Hence, your posted code only needs a COUNT() function added:

SELECT CAST(COUNT(1) AS BIT) AS Expr1
FROM [User]
WHERE (UserID = 20070022)

Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:

s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum

Clear:both gives you that space between them.

For example your code:

  <div style="float:left">Hello</div>
  <div style="float:right">Howdy dere pardner</div>

Will currently display as :

Hello  ...................   Howdy dere pardner

If you add the following to above snippet,

  <div style="clear:both"></div>

In between them it will display as:

Hello ................ 
                       Howdy dere pardner

giving you that space between hello and Howdy dere pardner.

Hi if your are looking for simple android image sliding with circle indicator you can download the complete code from here http://javaant.com/viewpager-with-circle-indicator-in-android/#.VysQQRV96Hs . please check the live demo which will give the clear idea.

The working solution for Integer number to binary conversion is below.

int main()
{
    int num=241; //Assuming 16 bit integer
    for(int i=15; i>=0; i--) cout<<((num >> i) & 1);
    cout<<endl;
    for(int i=0; i<16; i++) cout<<((num >> i) & 1);
    cout<<endl;
    return 0;
}

You can capture the cout<< part based on your own requirement.

Installing cv2 or opencv-python using pip is sometimes a problem. I was having the same problem of installing cv2 with pip. The installation wasn't a problem the problem was to import cv2 after installation. I was getting an Import Error so to fix this i import main from pip to install opencv-python. Try to run the following code in your python file then opencv-python will be installed

from pip._internal import main as install
try:
    import cv2
except ImportError as e:
    install(["install", "opencv-python"])
finally:
    pass

If there's Lodash in your project, use upperFirst.

The best function to use for this is os.path.getmtime(). Internally, this just uses os.stat(filename).st_mtime.

The datetime module is the best manipulating timestamps, so you can get the modification date as a datetime object like this:

import os
import datetime
def modification_date(filename):
    t = os.path.getmtime(filename)
    return datetime.datetime.fromtimestamp(t)

Usage example:

>>> d = modification_date('/var/log/syslog')
>>> print d
2009-10-06 10:50:01
>>> print repr(d)
datetime.datetime(2009, 10, 6, 10, 50, 1)

If you have a text as

var sampleText ="ä_öü_ßÄ_ TESTED Ö_Ü!@#$%^&())(&&++===.XYZ"

To replace all special character (!@#$%^&())(&&++= ==.) without replacing the characters(including umlaut)

Use below regex

sampleText = sampleText.replace(/[`~!@#$%^&*()|+-=?;:'",.<>{}[]\/\s]/gi,'');

OUTPUT : sampleText = "ä_öü_ßÄ____TESTED_Ö_Ü_____________________XYZ"

This would replace all with an underscore which is provided as second argument to the replace function.You can add whatever you want as per your requirement

It could be quotes themselves that are the entire problem. I had a similar problem and it was due to quotes around the column name in the CREATE TABLE statement. Note there were no whitespace issues, just quotes causing problems.

The column looked like it was called anID but was really called "anID". The quotes don't appear in typical queries so it was hard to detect (for this postgres rookie). This is on postgres 9.4.1

Some more detail:

Doing postgres=# SELECT * FROM test; gave:

  anID | value 
 ------+-------
     1 | hello
     2 | baz
     3 | foo (3 rows)

but trying to select just the first column SELECT anID FROM test; resulted in an error:

ERROR:  column "anid" does not exist 
LINE 1: SELECT anID FROM test;
                ^

Just looking at the column names didn't help: postgres=# \d test;

          Table "public.test"
 Column |       Type        | Modifiers 
--------+-------------------+-----------
 anID   | integer           | not null
 value  | character varying | 
Indexes:
    "PK on ID" PRIMARY KEY, btree ("anID")

but in pgAdmin if you click on the column name and look in the SQL pane it populated with:

ALTER TABLE test ADD COLUMN "anID" integer;
ALTER TABLE test ALTER COLUMN "anID" SET NOT NULL;

and lo and behold there are the quoutes around the column name. So then ultimately postgres=# select "anID" FROM test; works fine:

Same moral, don't use quotes.

Just change the directory to another one and come back. Probably that one has been deleted or moved.

You would do:

char c = str[1];

Or even:

char c = "Hello"[1];

edit: updated to find the "E".

Try adding the profile attribute to your head tag and use "image/x-icon" for the type attribute:

<head profile="http://www.w3.org/2005/10/profile">
<link rel="icon" type="image/x-icon" href="img/favicon.ico">

If the above code doesn't work, try using the full icon path for the href attribute:

<head profile="http://www.w3.org/2005/10/profile">
<link rel="icon" type="image/x-icon" href="http://example.com/img/favicon.ico">

def norm(vector):
    return sqrt(sum(x * x for x in vector))    

def cosine_similarity(vec_a, vec_b):
        norm_a = norm(vec_a)
        norm_b = norm(vec_b)
        dot = sum(a * b for a, b in zip(vec_a, vec_b))
        return dot / (norm_a * norm_b)

This method seems to be somewhat faster than using sklearn's implementation if you pass in one pair of vectors at a time.

Once your stored procedure is imported in your model, you can right click in it (from the model browser, in the Context.Store/Stored Procedures section), and click Add Function Import. If you need a complex type as a result, you can create it right there.

GETDATE() returns current date and time.

If last year starts in midnight of current day last year (like in original example) you should use something like:

DECLARE @start datetime
SET @start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) --  getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= @start

PHP HAS multithreading, its just not enabled by default, there is an extension called pthreads which does exactly that. You'll need php compiled with ZTS though. (Thread Safe) Links:

Static memory allocation is allocated memory before execution pf program during compile time. Dynamic memory alocation is alocated memory during execution of program at run time.

PHPEclipse is as close to Eclipse java power as it could get. Eclipse PDT is much weaker (last time I checked).

In SQL server 2005 new datatypes were introduced: varchar(max) and nvarchar(max) They have the advantages of the old text type: they can contain op to 2GB of data, but they also have most of the advantages of varchar and nvarchar. Among these advantages are the ability to use string manipulation functions such as substring().

Also, varchar(max) is stored in the table's (disk/memory) space while the size is below 8Kb. Only when you place more data in the field, it's is stored out of the table's space. Data stored in the table's space is (usually) retrieved quicker.

In short, never use Text, as there is a better alternative: (n)varchar(max). And only use varchar(max) when a regular varchar is not big enough, ie if you expect teh string that you're going to store will exceed 8000 characters.

As was noted, you can use SUBSTRING on the TEXT datatype,but only as long the TEXT fields contains less than 8000 characters.

If you are creating a div and trying to add a title to it.

Try

var myDiv= document.createElement("div");
myDiv.setAttribute('title','mytitle');

Try doing a FLUSH PRIVILEGES;. This MySQL bug post on that error code appears to report some success in a case similar to yours after flushing privs. 

When comparing only the date of the datatimes, use the Date property. So this should work fine for you

datetime1.Date == datetime2.Date

Old question, but thought I'd share my solution anyway. Pretty simple.

dicta_set = set(dicta.items()) # creates a set of tuples (k/v pairs)
dictb_set = set(dictb.items())
setdiff = dictb_set.difference(dicta_set) # any set method you want for comparisons
for k, v in setdiff: # unpack the tuples for processing
    print(f"k/v differences = {k}: {v}")

This code creates two sets of tuples representing the k/v pairs. It then uses a set method of your choosing to compare the tuples. Lastly, it unpacks the tuples (k/v pairs) for processing.

Why not have a hidden anchor tag on the page with the target set as you need, then simulate clicking it when you need the pop out?

How can I simulate a click to an anchor tag?

This would work in the cases where the window.open did not work

• zz - move current line to the middle of the screen
  (Careful with zz, if you happen to have Caps Lock on accidentally, you will save and exit vim!)
• zt - move current line to the top of the screen
• zb - move current line to the bottom of the screen

as.character() would be the general way rather than use paste() for its side effect

> v <- 20081101
> date <- as.Date(as.character(v), format = "%Y%m%d")
> date
[1] "2008-11-01"

(I presume this is a simple example and something like this:

v <- "20081101"

isn't possible?)

If you want to generate a random float in a range, try a next solution.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>


float
random_float(const float min, const float max)
{
    if (max == min) return min;
    else if (min < max) return (max - min) * ((float)rand() / RAND_MAX) + min;

    // return 0 if min > max
    return 0;
}


int
main (const int argc, const char *argv[])
{
    srand(time(NULL));

    char line[] = "-------------------------------------------";

    float data[10][2] = {
        {-10, 10},
        {-5., 5},
        {-1, 1},
        {-0.25, -0.15},
        {1.5, 1.52},
        {-1700, 8000},
        {-0.1, 0.1},
        {-1, 0},
        {-1, -2},
        {1.2, 1.1}
    };

    puts(line);
    puts("     From    |    Result    |      To");
    puts(line);


    int i;
    for (i = 0; i < 10; ++i) {
        printf("%12f | %12f | %12f\n", data[i][0], random_float(data[i][0], data[i][1]), data[i][1]);
    }

    puts(line);

    return 0;
}

A result (values is fickle)

Direct Closure serialisation is not allowed by PHP. But you can use powefull class like PHP Super Closure : https://github.com/jeremeamia/super_closure

This class is really simple to use and is bundled into the laravel framework for the queue manager.

From the github documentation :

$helloWorld = new SerializableClosure(function ($name = 'World') use ($greeting) {
    echo "{$greeting}, {$name}!\n";
});

$serialized = serialize($helloWorld);

Let me know if this is what you need. Or some thing is missing. I went through the other answers and found that jquery has been used . I took it on assumption that you need css solution . If I am missing any more point please mention :)

I had the same problem, but found out that the dump file was actually a MSSQL Server backup, not MySQL.

Sometimes legacy backup files play tricks on us. Check your dump file.

On terminal window:

~$ cat mybackup.dmp 

The result was:

TAPE??G?"5,^}???Microsoft SQL ServerSPAD^LSFMB8..... etc...

To stop processing the cat command:

CTRL + C

The only way to pass values to a parent constructor is through an initialization list. The initilization list is implemented with a : and then a list of classes and the values to be passed to that classes constructor.

Class2::Class2(string id) : Class1(id) {
....
}

Also remember that if you have a constructor that takes no parameters on the parent class, it will be called automatically prior to the child constructor executing.

This should work:

window.onload = function() {
  document.getElementById('about').className = 'expand';
};

Or if you're using jQuery:

$(function() {
  $('#about').addClass('expand');
});

Here's the pseudo-code which should be convertible into any procedural language:

array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362]
number = 112
print closest (number, array)

def closest (num, arr):
    curr = arr[0]
    foreach val in arr:
        if abs (num - val) < abs (num - curr):
            curr = val
    return curr

It simply works out the absolute differences between the given number and each array element and gives you back one of the ones with the minimal difference.

For the example values:

number = 112  112  112  112  112  112  112  112  112  112
array  =   2   42   82  122  162  202  242  282  322  362
diff   = 110   70   30   10   50   90  130  170  210  250
                         |
                         +-- one with minimal absolute difference.

As a proof of concept, here's the Python code I used to show this in action:

def closest (num, arr):
    curr = arr[0]
    for index in range (len (arr)):
        if abs (num - arr[index]) < abs (num - curr):
            curr = arr[index]
    return curr

array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362]
number = 112
print closest (number, array)

And, if you really need it in Javascript, see below for a complete HTML file which demonstrates the function in action:

<html>
    <head></head>
    <body>
        <script language="javascript">
            function closest (num, arr) {
                var curr = arr[0];
                var diff = Math.abs (num - curr);
                for (var val = 0; val < arr.length; val++) {
                    var newdiff = Math.abs (num - arr[val]);
                    if (newdiff < diff) {
                        diff = newdiff;
                        curr = arr[val];
                    }
                }
                return curr;
            }
            array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362];
            number = 112;
            alert (closest (number, array));
        </script>
    </body>
</html>

Now keep in mind there may be scope for improved efficiency if, for example, your data items are sorted (that could be inferred from the sample data but you don't explicitly state it). You could, for example, use a binary search to find the closest item.

You should also keep in mind that, unless you need to do it many times per second, the efficiency improvements will be mostly unnoticable unless your data sets get much larger.

If you do want to try it that way (and can guarantee the array is sorted in ascending order), this is a good starting point:

<html>
    <head></head>
    <body>
        <script language="javascript">
            function closest (num, arr) {
                var mid;
                var lo = 0;
                var hi = arr.length - 1;
                while (hi - lo > 1) {
                    mid = Math.floor ((lo + hi) / 2);
                    if (arr[mid] < num) {
                        lo = mid;
                    } else {
                        hi = mid;
                    }
                }
                if (num - arr[lo] <= arr[hi] - num) {
                    return arr[lo];
                }
                return arr[hi];
            }
            array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362];
            number = 112;
            alert (closest (number, array));
        </script>
    </body>
</html>

It basically uses bracketing and checking of the middle value to reduce the solution space by half for each iteration, a classic O(log N) algorithm whereas the sequential search above was O(N):

0  1  2   3   4   5   6   7   8   9  <- indexes
2 42 82 122 162 202 242 282 322 362  <- values
L             M                   H  L=0, H=9, M=4, 162 higher, H<-M
L     M       H                      L=0, H=4, M=2, 82 lower/equal, L<-M
      L   M   H                      L=2, H=4, M=3, 122 higher, H<-M
      L   H                          L=2, H=3, difference of 1 so exit
          ^
          |
          H (122-112=10) is closer than L (112-82=30) so choose H

As stated, that shouldn't make much of a difference for small datasets or for things that don't need to be blindingly fast, but it's an option you may want to consider.

I think you were planning to use Angular template reference variable based on your html template.

 // in html
 <input #nameInput type="text" class="form-control" placeholder=''/>

 // in add-player.ts file
 import { OnInit, ViewChild, ElementRef } from '@angular/core';

 export class AddPlayerComponent implements OnInit {
   @ViewChild('nameInput') nameInput: ElementRef;

   constructor() { }

   ngOnInit() { }

   addPlayer() {
     // you can access the input value via the following syntax.
     console.log('player name: ', this.nameInput.nativeElement.value);
   }
 }

There are several ways to do an email from HTML. Typically you see people doing a mailto like so:

<a href="mailto:[email protected]">Click to email</a>

But if you are doing it from a button you may want to look into a javascript solution.

CSV isn't quite that simple. Depending on the limits of the data you have, you might have to worry about quoted values (which may contain commas and newlines) and escaping quotes.

So if your data are restricted enough can get away with simple comma-splitting fine, shell script can do that easily. If, on the other hand, you need to parse CSV ‘properly’, bash would not be my first choice. Instead I'd look at a higher-level scripting language, for example Python with a csv.reader.

It should be MM for months. You are asking for minutes.

DateTime.Now.ToString("dd/MM/yyyy");

See Custom Date and Time Format Strings on MSDN for details.

and awk as well

The obligatory answer using XSLT:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="no" encoding="UTF-8"/>

  <xsl:template match="/|comment()|processing-instruction()">
    <xsl:copy>
      <xsl:apply-templates/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*">
    <xsl:element name="{local-name()}">
      <xsl:apply-templates select="@*|node()"/>
    </xsl:element>
  </xsl:template>

  <xsl:template match="@*">
    <xsl:attribute name="{local-name()}">
      <xsl:value-of select="."/>
    </xsl:attribute>
  </xsl:template>

</xsl:stylesheet>

This seems to be the cleanest way to do

if (foo === 1) {

} else if (bar === 99) {

} else if (foo === 2) {

} else {

}

in the template:

<ng-container *ngIf="foo === 1; else elseif1">foo === 1</ng-container>
<ng-template #elseif1>
    <ng-container *ngIf="bar === 99; else elseif2">bar === 99</ng-container>
</ng-template>
<ng-template #elseif2>
    <ng-container *ngIf="foo === 2; else else1">foo === 2</ng-container>
</ng-template>
<ng-template #else1>else</ng-template>

Notice that it works like a proper else if statement should when the conditions involve different variables (only 1 case is true at a time). Some of the other answers don't work right in such a case.

aside: gosh angular, that's some really ugly else if template code...

Here's a fast one-line test for this:

if (length(max(abs(center - rect_mid) - rect_halves, 0)) <= radius ) {
  // They intersect.
}

This is the axis-aligned case where rect_halves is a positive vector pointing from the rectangle middle to a corner. The expression inside length() is a delta vector from center to a closest point in the rectangle. This works in any dimension.

Static variables (file scope and function static) are initialized to zero:

int x; // zero
int y = 0; // also zero

void foo() {
    static int x; // also zero
}

Non-static variables (local variables) are indeterminate. Reading them prior to assigning a value results in undefined behavior.

void foo() {
    int x;
    printf("%d", x); // the compiler is free to crash here
}

In practice, they tend to just have some nonsensical value in there initially - some compilers may even put in specific, fixed values to make it obvious when looking in a debugger - but strictly speaking, the compiler is free to do anything from crashing to summoning demons through your nasal passages.

As for why it's undefined behavior instead of simply "undefined/arbitrary value", there are a number of CPU architectures that have additional flag bits in their representation for various types. A modern example would be the Itanium, which has a "Not a Thing" bit in its registers; of course, the C standard drafters were considering some older architectures.

Attempting to work with a value with these flag bits set can result in a CPU exception in an operation that really shouldn't fail (eg, integer addition, or assigning to another variable). And if you go and leave a variable uninitialized, the compiler might pick up some random garbage with these flag bits set - meaning touching that uninitialized variable may be deadly.

The most recent versions of hibernate JPA provider applies the bean validation constraints (JSR 303) like @NotNull to DDL by default (thanks to hibernate.validator.apply_to_ddl property defaults to true). But there is no guarantee that other JPA providers do or even have the ability to do that.

You should use bean validation annotations like @NotNull to ensure, that bean properties are set to a none-null value, when validating java beans in the JVM (this has nothing to do with database constraints, but in most situations should correspond to them).

You should additionally use the JPA annotation like @Column(nullable = false) to give the jpa provider hints to generate the right DDL for creating table columns with the database constraints you want. If you can or want to rely on a JPA provider like Hibernate, which applies the bean validation constraints to DDL by default, then you can omit them.

Numpy will be suitable for most people, but you can also do matrices in Sympy

Try running these commands at http://live.sympy.org/

M = Matrix([[1, 3], [-2, 3]])
M
M**-1

For fun, try M**(1/2)

this is trivially easy, why are so many people making such bad suggestions? @Bora was the closest, but this is the most robust

/***
 * returns the month in words for a given month number
 */
date("F", strtotime(date("Y")."-".$month."-01"));

this is the way to do it

I like the previous 'git-interactive-merge' answer, but there's one easier. Let Git do this for you using a rebase combination of interactive and onto:

      A---C1---o---C2---o---o feature
     /
----o---o---o---o master

So the case is you want C1 and C2 from the 'feature' branch (branch point 'A'), but none of the rest for now.

# git branch temp feature
# git checkout master
# git rebase -i --onto HEAD A temp

Which, as in the previous answer, drops you in to the interactive editor where you select the 'pick' lines for C1 and C2 (as above). Save and quit, and then it will proceed with the rebase and give you branch 'temp' and also HEAD at master + C1 + C2:

      A---C1---o---C2---o---o feature
     /
----o---o---o---o-master--C1---C2 [HEAD, temp]

Then you can just update master to HEAD and delete the temp branch and you're good to go:

# git branch -f master HEAD
# git branch -d temp

Reloading the configuration file (my.cnf) cannot be done without restarting the mysqld server.

FLUSH LOGS only rotates a few log files.

SET @@...=... sets it for anyone not yet logged in, but it will go away after the next restart. But that gives a clue... Do the SET, and change my.cnf; that way you are covered. Caveat: Not all settings can be performed via SET.

New with MySQL 8.0...

SET PERSIST ... will set the global setting and save it past restarts. Nearly all settings can be adjusted this way.

You can't truly do it in "standard" C, because the size of an int and of a char aren't fixed. Let's say you are using a compiler under Windows or Linux on an intel PC...

int i = 5;
char a = ((char*)&i)[0];
char b = ((char*)&i)[1];

Remember of endianness of your machine! And that int are "normally" 32 bits, so 4 chars!

But you probably meant "i want to stringify a number", so ignore this response :-)

you just need to get the absolute-path of the file, since the file you are looking for doesnt exist in the eclipse's runtime workspace you can use - getProperty() or getLocationURI() methods to get the absolute-path of the file

LEA (Load Effective Address) is a shift-and-add instruction. It was added to 8086 because hardware is there to decode and calculate adressing modes.

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

You have to use the TO_NUMBER function:

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

In Laravel 7.x and above, you can just do:

$data = Images::all()->random(4);

public static List<HtmlNode> GetTagsWithClass(string html,List<string> @class)
    {
        // LoadHtml(html);           
        var result = htmlDocument.DocumentNode.Descendants()
            .Where(x =>x.Attributes.Contains("class") && @class.Contains(x.Attributes["class"].Value)).ToList();          
        return result;
    }      

"Map<String , String > map = new HapshMap<String , String>;
 map.add("one","java");
 map.add("two" ,"spring");
 Set<Entry<String,String>> set =  map.entrySet();
 List<Entry<String , String>> list = new ArrayList<Entry<String , String>>    (set);
 for(Entry<String , String> entry : list ) {
   System.out.println(entry.getKey());
   System.out.println(entry.getValue());
 } "

You are getting the error because $ret is not an array.

To get rid of the error, at the start of your function, define it with this line: $ret = array();

It appears that the get_tags() call is returning nothing, so the foreach is not run, which means that $ret isn't defined.

After instantiating a Formatter I usually set formatter.converter = gmtime. So in order for @unutbu's answer to work in this case you'll need:

class MyFormatter(logging.Formatter):
    def formatTime(self, record, datefmt=None):
        ct = self.converter(record.created)
        if datefmt:
            s = time.strftime(datefmt, ct)
        else:
            t = time.strftime("%Y-%m-%d %H:%M:%S", ct)
            s = "%s.%03d" % (t, record.msecs)
        return s

There is no difference at all!

1) git checkout -b branch origin/branch

If there is no --track and no --no-track, --track is assumed as default. The default can be changed with the setting branch.autosetupmerge.

In effect, 1) behaves like git checkout -b branch --track origin/branch.

2) git checkout --track origin/branch

“As a convenience”, --track without -b implies -b and the argument to -b is guessed to be “branch”. The guessing is driven by the configuration variable remote.origin.fetch.

In effect, 2) behaves like git checkout -b branch --track origin/branch.

As you can see: no difference.

But it gets even better:

3) git checkout branch

is also equivalent to git checkout -b branch --track origin/branch if “branch” does not exist yet but “origin/branch” does<sup>1</sup>.

All three commands set the “upstream” of “branch” to be “origin/branch” (or they fail).

Upstream is used as reference point of argument-less git status, git push, git merge and thus git pull (if configured like that (which is the default or almost the default)).

E.g. git status tells you how far behind or ahead you are of upstream, if one is configured.

git push is configured to push the current branch upstream by default<sup>2</sup> since git 2.0.

<sup>1 ...and if “origin” is the only remote having “branch”
2 the default (named “simple”) also enforces for both branch names to be equal</sup>

android:gravity can be used on a Layout to align its children.

android:layout_gravity can be used on any view to align itself in its parent.

NOTE: If self or children is not centering as expected, check if width/height is match_parent and change to something else

Here is a snippet from my perl script to do this:

print OUTPUT "set arrow from $x1,$y1 to $x1,$y2 nohead lc rgb \'red\'\n";

As you might guess from above, it's actually drawn as a "headless" arrow.

1. You need

   @ManagedBean(name="userBean")

2. Make sure you have getUser() method.

3. Type of setUser() method should be void.

4. Make sure that User class has proper setters and getters as well.

You cant access PHP session variables/values in JS, one is server side (PHP), the other client side (JS).

What you can do is pass or return the SESSION value to your JS, by say, an AJAX call. In your JS, make a call to a PHP script which simply outputs for return to your JS the SESSION variable's value, then use your JS to handle this returned information.

Alternatively store the value in a COOKIE, which can be accessed by either framework..though this may not be the best approach in your situation.

OR you can generate some JS in your PHP which returns/sets the variable, i.e.:

<? php
echo "<script type='text/javascript'>
    alert('".json_encode($_SESSION['msg'])."');
</script>";
?>

Given that a list can hold any type of object, there is no built in method which allows you to sum all the elements. You could do something like this:

int sum = 0;

for( Integer i : ( ArrayList<Integer> )tt ) {
  sum += i;
}

Alternatively you could create your own container type which inherits from ArrayList but also implements a method called sum() which implements the code above.

I easily solve this problem by right clicking on my solution and then clicking on the Enable NuGet Package Restore option

(P.S: Ensure that you have the Nuget Install From Tools--> Extensions and Update--> Nuget Package Manager for Visual Studio 2013. If not install this extention first)

Hope it helps.

There is another the error happening which related to the order when calling initializing global variables. I've had the sample of code has similar error FailedPreconditionError (see above for traceback): Attempting to use uninitialized value W

def linear(X, n_input, n_output, activation = None):
    W = tf.Variable(tf.random_normal([n_input, n_output], stddev=0.1), name='W')
    b = tf.Variable(tf.constant(0, dtype=tf.float32, shape=[n_output]), name='b')
    if activation != None:
        h = tf.nn.tanh(tf.add(tf.matmul(X, W),b), name='h')
    else:
        h = tf.add(tf.matmul(X, W),b, name='h')
    return h

from tensorflow.python.framework import ops
ops.reset_default_graph()
g = tf.get_default_graph()
print([op.name for op in g.get_operations()])
with tf.Session() as sess:
    # RUN INIT
    sess.run(tf.global_variables_initializer())
    # But W hasn't in the graph yet so not know to initialize 
    # EVAL then error
    print(linear(np.array([[1.0,2.0,3.0]]).astype(np.float32), 3, 3).eval())

You should change to following

from tensorflow.python.framework import ops
ops.reset_default_graph()
g = tf.get_default_graph()
print([op.name for op in g.get_operations()])
with tf.Session() as 
    # NOT RUNNING BUT ASSIGN
    l = linear(np.array([[1.0,2.0,3.0]]).astype(np.float32), 3, 3)
    # RUN INIT
    sess.run(tf.global_variables_initializer())
    print([op.name for op in g.get_operations()])
    # ONLY EVAL AFTER INIT
    print(l.eval(session=sess))

Not done this yet myself, but a quick bit of Google-Fu reveals a tech tip on blogs.oracle.com with examples of exactly what you ask for.

Example taken from the blog post:

MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("name1", "val1");
formData.add("name2", "val2");
ClientResponse response = webResource
    .type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
    .post(ClientResponse.class, formData);

That any help?

div:nth-child(4n+4) 

See: http://css-tricks.com/how-nth-child-works/

this is what i did

first execute create database x. x is the name of your old database eg the name of the mdf.

Then open sql sever configration and stop the sql sever.

There after browse to the location of your new created database it should be under program file, in my case is

C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQL\MSSQL\DATA

and repleace the new created mdf and Idf with the old files/database.

then simply restart the sql server and walla :)

For:

2 mod 4

We can use this little formula I came up with after thinking a bit, maybe it's already defined somewhere I don't know but works for me, and its really useful.

A mod B = C where C is the answer

K * B - A = |C| where K is how many times B fits in A

2 mod 4 would be:

0 * 4 - 2 = |C|

C = |-2| => 2

Hope it works for you :)

A solution that I like, because it keeps rspec output separate from actual rails log output, is to do the following:

• Open a second terminal window or tab, and arrange it so that you can see both the main terminal you're running rspec on as well as the new one.
• Run a tail command in the second window so you see the rails log in the test environment. By default this can be like $ tail -f $RAILS_APP_DIR/logs/test.log or tail -f $RAILS_APP_DIR\logs\test.log for Window users
• Run your rspec suites

If you are running a multi-pane terminal like iTerm, this becomes even more fun and you have rspec and the test.log output side by side.

Functionality is supposed to be broken in jQuery 1.5.

Since jQuery 1.5.1 you should use xhrFields param.

$.ajaxSetup({
    type: "POST",
    data: {},
    dataType: 'json',
    xhrFields: {
       withCredentials: true
    },
    crossDomain: true
});

You can use the react-moment package

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

Most of the answers suggest either using a loop with equals to check if the enum exists or using try/catch with enum.valueOf(). I wanted to know which method is faster and tried it. I am not very good at benchmarking, so please correct me if I made any mistakes.

Heres the code of my main class:

    package enumtest;

public class TestMain {

    static long timeCatch, timeIterate;
    static String checkFor;
    static int corrects;

    public static void main(String[] args) {
        timeCatch = 0;
        timeIterate = 0;
        TestingEnum[] enumVals = TestingEnum.values();
        String[] testingStrings = new String[enumVals.length * 5];
        for (int j = 0; j < 10000; j++) {
            for (int i = 0; i < testingStrings.length; i++) {
                if (i % 5 == 0) {
                    testingStrings[i] = enumVals[i / 5].toString();
                } else {
                    testingStrings[i] = "DOES_NOT_EXIST" + i;
                }
            }

            for (String s : testingStrings) {
                checkFor = s;
                if (tryCatch()) {
                    ++corrects;
                }
                if (iterate()) {
                    ++corrects;
                }
            }
        }

        System.out.println(timeCatch / 1000 + "us for try catch");
        System.out.println(timeIterate / 1000 + "us for iterate");
        System.out.println(corrects);
    }

    static boolean tryCatch() {
        long timeStart, timeEnd;
        timeStart = System.nanoTime();
        try {
            TestingEnum.valueOf(checkFor);
            return true;
        } catch (IllegalArgumentException e) {
            return false;
        } finally {
            timeEnd = System.nanoTime();
            timeCatch += timeEnd - timeStart;
        }

    }

    static boolean iterate() {
        long timeStart, timeEnd;
        timeStart = System.nanoTime();
        TestingEnum[] values = TestingEnum.values();
        for (TestingEnum v : values) {
            if (v.toString().equals(checkFor)) {
                timeEnd = System.nanoTime();
                timeIterate += timeEnd - timeStart;
                return true;
            }
        }
        timeEnd = System.nanoTime();
        timeIterate += timeEnd - timeStart;
        return false;
    }
}

This means, each methods run 50000 times the lenght of the enum I ran this test multiple times, with 10, 20, 50 and 100 enum constants. Here are the results:

• 10: try/catch: 760ms | iteration: 62ms
• 20: try/catch: 1671ms | iteration: 177ms
• 50: try/catch: 3113ms | iteration: 488ms
• 100: try/catch: 6834ms | iteration: 1760ms

These results were not exact. When executing it again, there is up to 10% difference in the results, but they are enough to show, that the try/catch method is far less efficient, especially with small enums.

Regular methods can be abstract when they are meant to be overridden by subclasses and provided with functionality. Imagine the class Foo is extended by Bar1, Bar2, Bar3 etc. So, each will have their own version of the abstract class according to their needs.

Now, static methods by definition belong to the class, they have nothing to do with the objects of the class or the objects of its subclasses. They don't even need them to exist, they can be used without instantiating the classes. Hence, they need to be ready-to-go and cannot depend on the subclasses to add functionality to them.

There are 3 relevant ways to send Data from client Side (HTML, Javascript, Vbscript ..etc) to Server Side (PHP, ASP, JSP ...etc)

1. HTML form Posting Request (GET or POST).
2. AJAX (This also comes under GET and POST)
3. Cookie

HTML form Posting Request (GET or POST)

This is most commonly used method, and we can send more Data through this method

AJAX

This is Asynchronous method and this has to work with secure way, here also we can send more Data.

Cookie

This is nice way to use small amount of insensitive data. this is the best way to work with bit of data.

In your case You can prefer HTML form post or AJAX. But before sending to server validate your json by yourself or use link like http://jsonlint.com/

If you have Json Object convert it into String using JSON.stringify(object), If you have JSON string send it as it is.

I should be like this:

$.post(submitAddress, { 'yourArrayName' : javaScriptArrayToSubmitToServer },
  function(response, status, xhr) {
    alert("POST returned: \n" + response + "\n\n");
  })

Let's try this way:

select 
    a.ip, 
    a.os, 
    a.hostname, 
    a.port, 
    a.protocol, 
    b.state
from a
left join b 
    on a.ip = b.ip 
        and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/

So, in where clause you can filter result set by column from right table only on this way:

...
where b.somecolumn <> (=) null

In your specific case, you can set the containing a element to be:

a {
    display: block;
    text-align: center;
}

JS Bin demo.

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

Follow these steps then you can create custom styles for your file upload form:

1.) This is the simple HTML form(please read the HTML comments I have written here bellow)

    <form action="#type your action here" method="POST" enctype="multipart/form-data">
    <div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" onclick="getFile()">Click to upload!</div>
    <!-- this is your file input tag, so i hide it!-->
    <div style='height: 0px;width: 0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>
    <!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
    <input type="submit" value='submit' >
    </form>

2.) Then use this simple script to pass the click event to file input tag.

    function getFile(){
        document.getElementById("upfile").click();
    }

Now you can use any type of a styling without worrying how to change default styles. I know this very well, because I have been trying to change the default styles for month and a half. believe me it's very hard because different browsers have different upload input tag. So use this one to build your custom file upload forms.Here is the full AUTOMATED UPLOAD code.

<html>
<style>
#yourBtn{
   position: relative;
   top: 150px;
   font-family: calibri;
   width: 150px;
   padding: 10px;
   -webkit-border-radius: 5px;
   -moz-border-radius: 5px;
   border: 1px dashed #BBB; 
   text-align: center;
   background-color: #DDD;
   cursor:pointer;
  }
</style>
<script type="text/javascript">
 function getFile(){
   document.getElementById("upfile").click();
 }
 function sub(obj){
    var file = obj.value;
    var fileName = file.split("\\");
    document.getElementById("yourBtn").innerHTML = fileName[fileName.length-1];
    document.myForm.submit();
    event.preventDefault();
  }
</script>
<body>
<center>
<form action="#type your action here" method="POST" enctype="multipart/form-data" name="myForm">
<div id="yourBtn" onclick="getFile()">click to upload a file</div>
<!-- this is your file input tag, so i hide it!-->
<!-- i used the onchange event to fire the form submission-->
<div style='height: 0px; width: 0px;overflow:hidden;'><input id="upfile" type="file" value="upload" onchange="sub(this)"/></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<!-- <input type="submit" value='submit' > -->
</form>
</center>
</body>
</html>

This question is quite old, but I have made it that way (in TYPO3).

Firstly, I have made a own accessible css-class which I can choose on every content element manually.

Then, I have made a outer three column element with 11 columns (1 - 9 - 1), finally, I have modified the column width of the first and third column with CSS to 12.499999995%.

Though the above answers have covered, I have just tried to add minute detail s which i see missing. The reason behind them(The Why).

Illustration:

Sample.java
---------------
    public class Sample{
        DependencyOne dependencyOne;
        DependencyTwo dependencyTwo;


        public SampleResponse methodOfSample(){
            dependencyOne.methodOne();
            dependencyTwo.methodTwo();

            ...

            return sampleResponse;
        }
    }

SampleTest.java
-----------------------
@RunWith(PowerMockRunner.class)
@PrepareForTest({ClassA.class})
public class SampleTest{

    @InjectMocks
    Sample sample;

    @Mock
    DependencyOne dependencyOne;

    @Mock
    DependencyTwo dependencyTwo;

    @Before
    public void init() {
        MockitoAnnotations.initMocks(this);
    }

    public void sampleMethod1_Test(){
        //Arrange the dependencies
        DependencyResponse dependencyOneResponse = Mock(sampleResponse.class);
        Mockito.doReturn(dependencyOneResponse).when(dependencyOne).methodOne();

        DependencyResponse dependencyTwoResponse = Mock(sampleResponse.class);
        Mockito.doReturn(dependencyOneResponse).when(dependencyTwo).methodTwo();

        //call the method to be tested
        SampleResponse sampleResponse = sample.methodOfSample() 

        //Assert
        <assert the SampleResponse here>
    }
}

Reference

You could make use of the Javascript DOM API. In particular, look at the createElement() method.

You could create a re-usable function that will create an image like so...

function show_image(src, width, height, alt) {
    var img = document.createElement("img");
    img.src = src;
    img.width = width;
    img.height = height;
    img.alt = alt;

    // This next line will just add it to the <body> tag
    document.body.appendChild(img);
}

Then you could use it like this...

<button onclick=

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

Just call die() without ever defining it. Your script will crash. :)

When I do this, I usually call discombobulate() instead, but the principle is the same.

(Actually, what this does is throw a ReferenceError, making it roughly the same as spudly's answer - but it's shorter to type, for debugging purposes.)

padding-right works for me in Firefox/Chrome on Windows but not in IE. Welcome to the wonderful world of IE standards non-compliance.

{ flex: 1, resizeMode: 'contain' } worked for me. I didn't need the aspectRatio

Below is one of the way by which you can achieve that, may not be an ideal way to do.

Have one method accepting both types of request, then check what type of request you received, is it of type "GET" or "POST", once you come to know that, do respective actions and the call one method which does common task for both request Methods ie GET and POST.

@RequestMapping(value = "/books")
public ModelAndView listBooks(HttpServletRequest request){
     //handle both get and post request here
     // first check request type and do respective actions needed for get and post.

    if(GET REQUEST){

     //WORK RELATED TO GET

    }else if(POST REQUEST){

      //WORK RELATED TO POST

    }

    commonMethod(param1, param2....);
}

I don't know if homework counts...

During my studies we rolled our own program to solve the Traveling Salesman problem.

The idea was to make a comparison on several criteria (difficulty to map the problem, performance, etc) and we also used other techniques such as Simulated annealing.

It worked pretty well, but it took us a while to understand how to do the 'reproduction' phase correctly: modeling the problem at hand into something suitable for Genetic programming really struck me as the hardest part...

It was an interesting course since we also dabbled with neural networks and the like.

I'd like to know if anyone used this kind of programming in 'production' code.

Try to check outline on button's focus:

button:focus {
    outline: blue auto 5px; 
}

If you have it, just set it to none.

Write a custom template filter:

from django.template.defaulttags import register
...
@register.filter
def get_item(dictionary, key):
    return dictionary.get(key)

(I use .get so that if the key is absent, it returns none. If you do dictionary[key] it will raise a KeyError then.)

usage:

{{ mydict|get_item:item.NAME }}

The problem

The problem is in the network layer. Here are the status codes explained:

• Connection refused: The peer is not listening on the respective network port you're trying to connect to. This usually means that either a firewall is actively denying the connection or the respective service is not started on the other site or is overloaded.

• Connection timed out: During the attempt to establish the TCP connection, no response came from the other side within a given time limit. In the context of urllib this may also mean that the HTTP response did not arrive in time. This is sometimes also caused by firewalls, sometimes by network congestion or heavy load on the remote (or even local) site.

In context

That said, it is probably not a problem in your script, but on the remote site. If it's occuring occasionally, it indicates that the other site has load problems or the network path to the other site is unreliable.

Also, as it is a problem with the network, you cannot tell what happened on the other side. It is possible that the packets travel fine in the one direction but get dropped (or misrouted) in the other.

It is also not a (direct) DNS problem, that would cause another error (Name or service not known or something similar). It could however be the case that the DNS is configured to return different IP addresses on each request, which would connect you (DNS caching left aside) to different addresses hosts on each connection attempt. It could in turn be the case that some of these hosts are misconfigured or overloaded and thus cause the aforementioned problems.

Debugging this

As suggested in the another answer, using a packet analyzer can help to debug the issue. You won't see much however except the packets reflecting exactly what the error message says.

To rule out network congestion as a problem you could use a tool like mtr or traceroute or even ping to see if packets get lost to the remote site. Note that, if you see loss in mtr (and any traceroute tool for that matter), you must always consider the first host where loss occurs (in the route from yours to remote) as the one dropping packets, due to the way ICMP works. If the packets get lost only at the last hop over a long time (say, 100 packets), that host definetly has an issue. If you see that this behaviour is persistent (over several days), you might want to contact the administrator.

Loss in a middle of the route usually corresponds to network congestion (possibly due to maintenance), and there's nothing you could do about it (except whining at the ISP about missing redundance).

If network congestion is not a problem (i.e. not more than, say, 5% of the packets get lost), you should contact the remote server administrator to figure out what's wrong. He may be able to see relevant infos in system logs. Running a packet analyzer on the remote site might also be more revealing than on the local site. Checking whether the port is open using netstat -tlp is definetly recommended then.

There is precedent for returning structures in the C (and hence C++) standard with the div, ldiv (and, in C99, lldiv) functions from <stdlib.h> (or <cstdlib>).

The 'mix of return value and return parameters' is usually the least clean.

Having a function return a status and return data via return parameters is sensible in C; it is less obviously sensible in C++ where you could use exceptions to relay failure information instead.

If there are more than two return values, then a structure-like mechanism is probably best.

Html Code:

 <select id="multiple" multiple="multiple" name="multiple">
  <option value=""> -- Select -- </option>
  <option value="1">Opt1</option>
  <option value="2">Opt2</option>
  <option value="3">Opt3</option>
  <option value="4">Opt4</option>
  <option value="5">Opt5</option>
 </select>   

JQuery Code:

$('#multiple :selected').each(function(i, sel){ 
    alert( $(sel).val() ); 

});

                           delimiter = delimiter,
                           quotechar = '"')
    data = [data for data in data_iter]
data_array = np.asarray(data, dtype = <whatever options>)

on 4.6 million rows with about 70 columns and found that the NumPy path took 2 min 16 secs and the csv-list comprehension method took 13 seconds.

I would recommend the csv-list comprehension method as it is most likely relies on pre-compiled libraries and not the interpreter as much as NumPy. I suspect the pandas method would have similar interpreter overhead.

    parentView.addConstraint(horizontalConstraint)

    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)

if you want to execute tasks parallel,you need call the method executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, "your task name") after Android version of 3.0; but this method is not exist before Android 3.0 and after 1.6 because it execute parallel by itself, So I suggest you customize your own AsyncTask class in your project,to avoid throw exception in different Android version.

I've found a way to pass parent data to component scope in Vue, i think it's a little a bit of a hack but maybe this will help you.

1) Reference data in Vue Instance as an external object (data : dataObj)

2) Then in the data return function in the child component just return parentScope = dataObj and voila. Now you cann do things like {{ parentScope.prop }} and will work like a charm.

Good Luck!

Using the solution showed in this question, System.Windows.Forms.Clipboard.SetText(...), results in the exception:

I am having the same problem. I also login using oauth (I am using RubyOnRails), but for logout, I do it with JavaScript using a link like this:

<a href="/logout" onclick="FB.logout();">Logout</a> 

This first calls the onclick function and performs a logout on facebook, and then the normal /logout function of my site is called.

Though I would prefer a serverside solution as well, but at least it does what I want, it logs me out on both sites.

I am also quite new to the Facebook integration stuff and played around the first time with it, but my general feeling is that the documentation is pretty spread all over the place with lots of outdated stuff.

That's definitely possible. We'll take a general case with Apache here.

Let's say you're a big Symfony2 fan and you would like to access your symfony website at http://symfony.local/ from 4 different computers (the main one hosting your website, as well as a Mac, a Windows and a Linux distro connected (wireless or not) to the main computer.

General Sketch:

1 Set up a virtual host:

You first need to set up a virtual host in your apache httpd-vhosts.conf file. On XAMP, you can find this file here: C:\xampp\apache\conf\extra\httpd-vhosts.conf. On MAMP, you can find this file here: Applications/MAMP/conf/apache/extra/httpd-vhosts.conf. This step prepares the Web server on your computer for handling symfony.local requests. You need to provide the name of the Virtual Host as well as the root/main folder of your website. To do this, add the following line at the end of that file. You need to change the DocumentRoot to wherever your main folder is. Here I have taken /Applications/MAMP/htdocs/Symfony/ as the root of my website.

<VirtualHost *:80>
    DocumentRoot "/Applications/MAMP/htdocs/Symfony/"
    ServerName symfony.local
</VirtualHost>

2 Configure your hosts file:

For the client (your browser in that case) to understand what symfony.local really means, you need to edit the hosts file on your computer. Everytime you type an URL in your browser, your computer tries to understand what it means! symfony.local doesn't mean anything for a computer. So it will try to resolve the name symfony.local to an IP address. It will do this by first looking into the hosts file on your computer to see if he can match an IP address to what you typed in the address bar. If it can't, then it will ask DNS servers. The trick here is to append the following to your hosts file.

• On MAC, this file is in /private/etc/hosts;
• On LINUX, this file is in /etc/hosts;
• On WINDOWS, this file is in \Windows\system32\private\etc\hosts;
• On WINDOWS 7, this file is in \Windows\system32\drivers\etc\hosts;
• On WINDOWS 10, this file is in \Windows\system32\drivers\etc\hosts;

Hosts file

##
# Host Database
# localhost is used to configure the loopback interface
##
#...
127.0.0.1           symfony.local

From now on, everytime you type symfony.local on this computer, your computer will use the loopback interface to connect to symfony.local. It will understand that you want to work on localhost (127.0.0.1).

3 Access symfony.local from an other computer:

We finally arrive to your main question which is:

How can I now access my website through an other computer?

Well this is now easy! We just need to tell the other computers how they could find symfony.local! How do we do this?

3a Get the IP address of the computer hosting the website:

We first need to know the IP address on the computer that hosts the website (the one we've been working on since the very beginning). In the terminal, on MAC and LINUX type ifconfig |grep inet, on WINDOWS type ipconfig. Let's assume the IP address of this computer is 192.168.1.5.

3b Edit the hosts file on the computer you are trying to access the website from.:

Again, on MAC, this file is in /private/etc/hosts; on LINUX, in /etc/hosts; and on WINDOWS, in \Windows\system32\private\etc\hosts (if you're using WINDOWS 7, this file is in \Windows\system32\drivers\etc\hosts).. The trick is now to use the IP address of the computer we are trying to access/talk to:

##
# Host Database
# localhost is used to configure the loopback interface
##
#...
192.168.1.5         symfony.local

4 Finally enjoy the results in your browser

You can now go into your browser and type http://symfony.local to beautifully see your website on different computers! Note that you can apply the same strategy if you are a OSX user to test your website on Internet Explorer via Virtual Box (if you don't want to use a Windows computer). This is beautifully explained in Crafting Your Windows / IE Test Environment on OSX.

You can also access your localhost from mobile devices

You might wonder how to access your localhost website from a mobile device. In some cases, you won't be able to modify the hosts file (iPhone, iPad...) on your device (jailbreaking excluded).

Well, the solution then is to install a proxy server on the machine hosting the website and connect to that proxy from your iphone. It's actually very well explained in the following posts and is not that long to set up:

On a Mac, I would recommend: Testing a Mac OS X web site using a local hostname on a mobile device: Using SquidMan as a proxy. It's a 100% free solution. Some people can also use Charles as a proxy server but it's 50$.

On Linux, you can adapt the Mac OS way above by using Squid as a proxy server.

On Windows, you can do that using Fiddler. The solution is described in the following post: Monitoring iPhone traffic with Fiddler

Edit 23/11/2017: Hey I don't want to modify my Hosts file

@Dre. Any possible way to access the website from another computer by not editing the host file manually? let's say I have 100 computers wanted to access the website

This is an interesting question, and as it is related to the OP question, let me help.

You would have to do a change on your network so that every machine knows where your website is hosted. Most everyday routers don't do that so you would have to run your own DNS Server on your network.

Let's pretend you have a router (192.168.1.1). This router has a DHCP server and allocates IP addresses to 100 machines on the network.

Now, let's say you have, same as above, on the same network, a machine at 192.168.1.5 which has your website. We will call that machine pompei.

$ echo $HOSTNAME
pompei

Same as before, that machine pompei at 192.168.1.5 runs an HTTP Server which serves your website symfony.local.

For every machine to know that symfony.local is hosted on pompei we will now need a custom DNS Server on the network which knows where symfony.local is hosted. Devices on the network will then be able to resolve domain names served by pompei internally.

3 simple steps.

Step 1: DNS Server

Set-up a DNS Server on your network. Let's have it on pompei for convenience and use something like dnsmasq.

Dnsmasq provides Domain Name System (DNS) forwarder, ....

We want pompei to run DNSmasq to handle DNS requests Hey, pompei, where is symfony.local and respond Hey, sure think, it is on 192.168.1.5 but don't take my word for it.

Go ahead install dnsmasq, dnsmasq configuration file is typically in /etc/dnsmasq.conf depending on your environment.

I personally use no-resolv and google servers server=8.8.8.8 server=8.8.8.4.

*Note:* ALWAYS restart DNSmasq if modifying /etc/hosts file as no changes will take effect otherwise.

Step 2: Firewall

To work, pompei needs to allow incoming and outgoing 'domain' packets, which are going from and to port 53. Of course! These are DNS packets and if pompei does not allow them, there is no way for your DNS server to be reached at all. Go ahead and open that port 53. On linux, you would classically use iptables for this.

Sharing what I came up with but you will very likely have to dive into your firewall and understand everything well.

#
# Allow outbound DNS port 53
#
 iptables -A INPUT -p tcp --dport 53 -j ACCEPT
 iptables -A INPUT -p udp --dport 53 -j ACCEPT

 iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT
 iptables -A OUTPUT -p udp --dport 53 -j ACCEPT

 iptables -A INPUT -p udp --sport 53 -j ACCEPT
 iptables -A INPUT -p tcp --sport 53 -j ACCEPT

 iptables -A OUTPUT -p tcp --sport 53 -j ACCEPT
 iptables -A OUTPUT -p udp --sport 53 -j ACCEPT

Step 3: Router

Tell your router that your dns server is on 192.168.1.5 now. Most of the time, you can just login into your router and change this manually very easily.

That's it, When you are on a machine and ask for symfony.local, it will ask your DNS Server where symfony.local is hosted, and as soon as it has received its answer from the DNS server, will then send the proper HTTP request to pompei on 192.168.1.5.

I let you play with this and enjoy the ride. These 2 steps are the main guidelines, so you will have to debug and spend a few hours if this is the first time you do it. Let's say this is a bit more advanced networking, there are primary DNS Server, secondary DNS Servers, etc.. Good luck!

The problem is that you remove the last comma in the string, not the comma if it's the last thing in the string. So you should put an if to check if the last char is ',' and change it if it is.

EDIT: Is it really that confusing?

'This, is a random string'

Your code finds the last comma from the string and stores only 'This, ' because, the last comma is after 'This' not at the end of the string.

In my case, setting httpErrors and the like in Web.config did not help to identify the issue.

Instead I did:

1. Activate "Failed Request Tracing" for the website with the error.
2. Configured a trace for HTTP errors 350-999 (just in case), although I suspected 500.
3. Called the erroneous URL again.
4. Watched in the log folder ("%SystemDrive%\inetpub\logs\FailedReqLogFiles" in my case).
5. Opened one of the XML files in Internet Explorer.

I then saw an entry with a detailed exception information. In my case it was

\?\C:\Websites\example.com\www\web.config ( 592) :Cannot add duplicate collection entry of type 'mimeMap' with unique key attribute 'fileExtension' set to '.json'

I now was able to resolve it and fix the error. After that I deactivated "Failed Request Tracing" again.

Imports VB = Microsoft.VisualBasic

End Sub

%0.1 cpu usage + high lag

Try the following:

echo a#b#c | awk -F"#" '{$1 = ""; $NF = ""; print}' OFS=""

This worked for me:

var start = new Date("2020-10-15T00:00:00.000+0000");
 //or
start = new date("2020-10-15T00:00:00.000Z");

collection.find({
    start_date:{
        $gte: start
    }
})...etc

Alternatively, if you want to solely obtain the current directory of the current NodeJS script, you could try something simple like this. Note that this will not work in the Node CLI itself:

var fs = require('fs'),
    path = require('path');

var dirString = path.dirname(fs.realpathSync(__filename));

// output example: "/Users/jb/workspace/abtest"
console.log('directory to start walking...', dirString);

If the javascript file is loaded from the admin dashboard, this javascript function will give you the root of your WordPress installation. I use this a lot when I'm building plugins that need to make ajax requests from the admin dashboard.

function getHomeUrl() {
  var href = window.location.href;
  var index = href.indexOf('/wp-admin');
  var homeUrl = href.substring(0, index);
  return homeUrl;
}

It depends where you put this initialisation.

If the array is static as in

char array[100] = {0};

int main(void)
{
...
}

then it is the compiler that reserves the 100 0 bytes in the data segement of the program. In this case you could have omitted the initialiser.

If your array is auto, then it is another story.

int foo(void)
{
char array[100] = {0};
...
}

In this case at every call of the function foo you will have a hidden memset.

The code above is equivalent to

int foo(void)
{ 
char array[100];

memset(array, 0, sizeof(array));
....
}

and if you omit the initializer your array will contain random data (the data of the stack).

If your local array is declared static like in

int foo(void)
{ 
static char array[100] = {0};
...
}

then it is technically the same case as the first one.

Whenever you 'see' something in the GUI (SSMS) and you're like "that's what I need", you can always run Sql Profiler to fish for the query that was used.

Run Sql Profiler. Attach it to your database of course.

Then right click in the GUI (in SSMS) and click "Refresh".
And then go see what Profiler "catches".

I got the below when I was in MyDatabase / Security / Users and clicked "refresh" on the "Users".

Again, I didn't come up with the WHERE clause and the LEFT OUTER JOIN, it was a part of the SSMS query. And this query is something that somebody at Microsoft has written (you know, the peeps who know the product inside and out, aka, the experts), so they are familiar with all the weird "flags" in the database.

But the SSMS/GUI -> Sql Profiler tricks works in many scenarios.

SELECT
u.name AS [Name],
'Server[@Name=' + quotename(CAST(
        serverproperty(N'Servername')
       AS sysname),'''') + ']' + '/Database[@Name=' + quotename(db_name(),'''') + ']' + '/User[@Name=' + quotename(u.name,'''') + ']' AS [Urn],
u.create_date AS [CreateDate],
u.principal_id AS [ID],
CAST(CASE dp.state WHEN N'G' THEN 1 WHEN 'W' THEN 1 ELSE 0 END AS bit) AS [HasDBAccess]
FROM
sys.database_principals AS u
LEFT OUTER JOIN sys.database_permissions AS dp ON dp.grantee_principal_id = u.principal_id and dp.type = 'CO'
WHERE
(u.type in ('U', 'S', 'G', 'C', 'K' ,'E', 'X'))
ORDER BY
[Name] ASC

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

You will find multiple different methods that people use and they each have there own place.

<?php if($first_condition): ?>
  /*$first_condition is true*/
<?php elseif ($second_condition): ?>
  /*$first_condition is false and $second_condition is true*/
<?php else: ?>
  /*$first_condition and $second_condition are false*/
<?php endif; ?>

If in your php.ini attribute short_open_tag = true (this is normally found on line 141 of the default php.ini file) you can replace your php open tag from <?php to <?. This is not advised as most live server environments have this turned off (including many CMS's like Drupal, WordPress and Joomla). I have already tested short hand open tags in Drupal and confirmed that it will break your site, so stick with <?php. short_open_tag is not on by default in all server configurations and must not be assumed as such when developing for unknown server configurations. Many hosting companies have short_open_tag turned off.

A quick search of short_open_tag in stackExchange shows 830 results. https://stackoverflow.com/search?q=short_open_tag That's a lot of people having problems with something they should just not play with.

with some server environments and applications, short hand php open tags will still crash your code even with short_open_tag set to true.

short_open_tag will be removed in PHP6 so don't use short hand tags.

all future PHP versions will be dropping short_open_tag

"It's been recommended for several years that you not use the short tag "short cut" and instead to use the full tag combination. With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context. But because this short cut has been a feature for such a long time, it's currently still supported for backwards compatibility, but we recommend you don't use them." – Jelmer Sep 25 '12 at 9:00 php: "short_open_tag = On" not working

Normally you write PHP like so: . However if allow_short_tags directive is enabled you're able to use: . Also sort tags provides extra syntax: which is equal to .

Short tags might seem cool but they're not. They causes only more problems. Oh... and IIRC they'll be removed from PHP6. Crozin answered Aug 24 '10 at 22:12 php short_open_tag problem

To answer the why part, I'd quote Zend PHP 5 certification guide: "Short tags were, for a time, the standard in the PHP world; however, they do have the major drawback of conflicting with XML headers and, therefore, have somewhat fallen by the wayside." – Fluffy Apr 13 '11 at 14:40 Are PHP short tags acceptable to use?

You may also see people use the following example:

<?php if($first_condition){ ?>
  /*$first_condition is true*/
<?php }else if ($second_condition){ ?>
  /*$first_condition is false and $second_condition is true*/
<?php }else{ ?>
  /*$first_condition and $second_condition are false*/
<?php } ?>

This will work but it is highly frowned upon as it's not considered as legible and is not what you would use this format for. If you had a PHP file where you had a block of PHP code that didn't have embedded tags inside, then you would use the bracket format.

The following example shows when to use the bracket method

<?php
if($first_condition){
   /*$first_condition is true*/
}else if ($second_condition){
   /*$first_condition is false and $second_condition is true*/
}else{
   /*$first_condition and $second_condition are false*/
}
?>

If you're doing this code for yourself you can do what you like, but if your working with a team at a job it is advised to use the correct format for the correct circumstance. If you use brackets in embedded html/php scripts that is a good way to get fired, as no one will want to clean up your code after you. IT bosses will care about code legibility and college professors grade on legibility.

UPDATE

based on comments from duskwuff its still unclear if shorthand is discouraged (by the php standards) or not. I'll update this answer as I get more information. But based on many documents found on the web about shorthand being bad for portability. I would still personally not use it as it gives no advantage and you must rely on a setting being on that is not on for every web host.

On Windows, you need to add the path %USERPROFILE%\AppData\Roaming\Python\Scripts to your path.

As a client-side developer I recommend to use blob URL, blob URL is a client-side URL which refers to a binary object

<video id="id" width="320" height="240"  type='video/mp4' controls  > </video>

in HTML leave your video src blank, and in JS fetch the video file using AJAX, make sure the response type is blob

window.onload = function() {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', 'mov_bbb.mp4', true);
    xhr.responseType = 'blob'; //important
    xhr.onload = function(e) {
        if (this.status == 200) {
            console.log("loaded");
            var blob = this.response;
            var video = document.getElementById('id');
            video.oncanplaythrough = function() {
                console.log("Can play through video without stopping");
                URL.revokeObjectURL(this.src);
            };
            video.src = URL.createObjectURL(blob);
            video.load();
        }
    };
    xhr.send();
}

Note: This method is not recommended for large file

EDIT

• Use cross-origin blocking for avoiding direct downloading

• if the video is delivered by an API Use different method (PUT/POST) instead of 'GET'

<td style="white-space: nowrap">

The nowrap attribute I believe is deprecated. The above is the preferred way.

I tried to uninstall/install and it did not work. I am running OSX 10.10.3 with Android Studio 1.2.1.1 on JDK 1.8.0_45-b14 and the solution I found to work is similar to Jorge Casariego's recommendation. Basically, out of the box you get a build error for a missing 'aidl' module so simply changing the Build Tools Version to not be version 23.0.0 rc1 will solve your problem. It appears to have a bug.

UPDATE After commenting on an Android issue on their tracker (https://code.google.com/p/android/issues/detail?id=175080) a project member from the Android Tools group commented that to use the Build Tools Version 23.0.0 rc1 you need to be using Android Gradle Plugin 1.3.0-beta1 (Android Studio comes configured with 1.2.3). He also noted (read the issue comments) that the IDE should have given an notification that you need to do this to make it work. For me I have not seen a notification and I've requested clarification from that project member. Nonetheless his guidance solved the issue perfectly so read on.

Solution: Open your build.gradle for your Project (not Module). Find the line classpath com.android.tools.build:gradle:xxx under dependencies where xxx is the Gradle Plugin version and make the update. Save and Rebuild your project. Here is the Android Gradle docs for managing your Gradle versions: https://developer.android.com/tools/revisions/gradle-plugin.html
