Try using an absolute path for the filename. And if you are using Windows, use getlasterror() to see the actual error message.

from sklearn import metrics              
import numpy as np
print(np.sqrt(metrics.mean_squared_error(y_test,y_predict)))

This is pretty easy with ProcessLifecycleOwner

Add these dependencies

implementation "android.arch.lifecycle:extensions:$project.archLifecycleVersion"
kapt "android.arch.lifecycle:compiler:$project.archLifecycleVersion"

In Kotlin:

class ForegroundBackgroundListener : LifecycleObserver {


    @OnLifecycleEvent(Lifecycle.Event.ON_START)
    fun startSomething() {
        Log.v("ProcessLog", "APP IS ON FOREGROUND")
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_STOP)
    fun stopSomething() {
        Log.v("ProcessLog", "APP IS IN BACKGROUND")
    }
}

Then in your base activity:

override fun onCreate() {
        super.onCreate()

        ProcessLifecycleOwner.get()
                .lifecycle
                .addObserver(
                        ForegroundBackgroundListener()
                                .also { appObserver = it })
    }

Private variables in python is more or less a hack: the interpreter intentionally renames the variable.

class A:
    def __init__(self):
        self.__var = 123
    def printVar(self):
        print self.__var

Now, if you try to access __var outside the class definition, it will fail:

 >>>x = A()
 >>>x.__var # this will return error: "A has no attribute __var"

 >>>x.printVar() # this gives back 123

But you can easily get away with this:

 >>>x.__dict__ # this will show everything that is contained in object x
               # which in this case is something like {'_A__var' : 123}

 >>>x._A__var = 456 # you now know the masked name of private variables
 >>>x.printVar() # this gives back 456

You probably know that methods in OOP are invoked like this: x.printVar() => A.printVar(x), if A.printVar() can access some field in x, this field can also be accessed outside A.printVar()...after all, functions are created for reusability, there is no special power given to the statements inside.

The game is different when there is a compiler involved (privacy is a compiler level concept). It know about class definition with access control modifiers so it can error out if the rules are not being followed at compile time

Made an improvement code by @Ipsita - for use asynchronous read\write file I/O

readonly string logPath = @"FilePath";
...
public async Task WriteToLogAsync(string dataToWrite)
{
    TextReader tr = new StreamReader(logPath);
    string data = await tr.ReadLineAsync();
    tr.Close();

    TextWriter tw = new StreamWriter(logPath);
    await tw.WriteLineAsync(data + dataToWrite);
    tw.Close();
}
...
await WriteToLogAsync("Write this to file");

Switch in combination with variable variables will give you more flexibility:

<?php
$p = 'home'; //For testing

$p = ( strpos($p, 'users') !== false? 'users': $p);
switch ($p) { 
    default:
        $varContainer = 'current_' . $p; //Stores the variable [$current_"xyORz"] into $varContainer
        ${$varContainer} = 'current'; //Sets the VALUE of [$current_"xyORz"] to 'current'
    break;

}
//For testing
echo $current_home;
?>

To learn more, checkout variable variables and the examples I submitted to php manual:
Example 1: http://www.php.net/manual/en/language.variables.variable.php#105293
Example 2: http://www.php.net/manual/en/language.variables.variable.php#105282

PS: This example code is SMALL AND SIMPLE, just the way I like it. It's tested and works too

Try to connect to repositroy with url: http://github.com/<user>/<project>.git (http except https)

In your case you should clone like this:

git clone http://github.com/<user>/<project>.git

If the following items meet your needs, you're in luck:

1. You want to convert an array of arrays like [['key','value1'], ['key2','value2'] (like what FormData gives you) into a key->value object like {key1: 'value1', key2: 'value2'} and the convert it to a JSON string.
2. You are targeting browsers/devices with the latest ES6 interpreter or are compiling with something like babel.
3. You want the tiniest way to accomplish this.

Here is the code you'll need:

const data = new FormData(document.querySelector('form'));
const json = JSON.stringify(Array.from(data).reduce((o,[k,v])=>(o[k]=v,o),{}));

Hope this helps someone.

git diff `git merge-base master branch`..branch

Merge base is the point where branch diverged from master.

Git diff supports a special syntax for this:

git diff master...branch

You must not swap the sides because then you would get the other branch. You want to know what changed in branch since it diverged from master, not the other way round.

Loosely related:

• Finding a branch point with Git?
• How can I see what branch another branch was forked from?

Note that .. and ... syntax does not have the same semantics as in other Git tools. It differs from the meaning specified in man gitrevisions.

Quoting man git-diff:

• git diff [--options] <commit> <commit> [--] [<path>…]

  This is to view the changes between two arbitrary <commit>.

• git diff [--options] <commit>..<commit> [--] [<path>…]

  This is synonymous to the previous form. If <commit> on one side is omitted, it will have the same effect as using HEAD instead.

• git diff [--options] <commit>...<commit> [--] [<path>…]

  This form is to view the changes on the branch containing and up to the second <commit>, starting at a common ancestor of both <commit>. "git diff A...B" is equivalent to "git diff $(git-merge-base A B) B". You can omit any one of <commit>, which has the same effect as using HEAD instead.

Just in case you are doing something exotic, it should be noted that all of the <commit> in the above description, except in the last two forms that use ".." notations, can be any <tree>.

For a more complete list of ways to spell <commit>, see "SPECIFYING REVISIONS" section in gitrevisions[7]. However, "diff" is about comparing two endpoints, not ranges, and the range notations ("<commit>..<commit>" and "<commit>...<commit>") do not mean a range as defined in the "SPECIFYING RANGES" section in gitrevisions[7].

I would go for substr() functionality in MySql.

Basically, this function takes account of three parameters i.e. substr(str,pos,len)

http://www.w3resource.com/mysql/string-functions/mysql-substr-function.php

SELECT * FROM artists 
WHERE lower(substr(name,1,1)) in ('a','b','c');

I tried adding dynamically created ListItem and assigning the selected value.

foreach(var item in yourListFromDB)
{
 ListItem listItem = new ListItem();
 listItem.Text = item.name;
 listItem.Value = Convert.ToString(item.value);
 listItem.Selected=item.isSelected;                 
  checkedListBox1.Items.Add(listItem);
}
checkedListBox1.DataBind();

avoid using binding the DataSource as it will not bind the checked/unchecked from DB.

Its possible you don't need to know depending on what you are doing with it.

String myString = object.toString();

or if object can be null

String myString = String.valueOf(object);

// file Foo.php
class Foo
{
  static function init() { /* ... */ }
}

Foo::init();

This way, the initialization happens when the class file is included. You can make sure this only happens when necessary (and only once) by using autoloading.

What are you trying to accomplish? If it's customization then you have a set of files to work with though that seems like a bad idea. Otherwise, I would suggest going with the full build of v4.1.x since that is the current release.

K8s completely works on the fundamental of the namespace. if you like to release all the resource related to specified namespace.

you can use the below mentioned :

kubectl delete namespace k8sdemo-app

Based on Doug Shore's method but make it more copy-paste friendly

You could manually set the cookie, but depending on your use case (and if you might want to add more types of persistent/session data in future) it might make more sense to use Django's sessions feature. This will let you get and set variables tied internally to the user's session cookie. Cool thing about this is that if you want to store a lot of data tied to a user's session, storing it all in cookies will add a lot of weight to HTTP requests and responses. With sessions the session cookie is all that is sent back and forth (though there is the overhead on Django's end of storing the session data to keep in mind).

Disable selection everywhere

input, textarea ,*[contenteditable=true] {
  -webkit-touch-callout:default;
  -webkit-user-select:text;
  -moz-user-select:text;
  -ms-user-select:text;
  user-select:text;
   }

 <BODY oncontextmenu="return false" onselectstart="return false" ondragstart="return false">

I think it would look better if we add border-color : transparent as per below:

<hr style="width: 100%; background-color: black; height: 1px; border-color : transparent;" />

If you don't put the border transparent it will be white and i don't think that is good all time.

Here is what I would do:

find /path/to/dir -type f -iname "*filename*" -print0 | xargs -0 sed -i '/searchstring/s/old/new/g'

this will look for all files containing filename in the file's name under the /path/to/dir, than for every file found, search for the line with searchstring and replace old with new.

Though if you want to omit looking for a specific file with a filename string in the file's name, than simply do:

find /path/to/dir -type f -print0 | xargs -0 sed -i '/searchstring/s/old/new/g'

This will do the same thing above, but to all files found under /path/to/dir.

I encourage you to try goMap jQuery plugin when working with Google Maps. For this kind of situation you can set hideByClick to true when creating markers:

$(function() { 
    $("#map").goMap({ 
        markers: [{  
            latitude: 56.948813, 
            longitude: 24.704004, 
            html: { 
                content: 'Click to marker', 
                popup:true 
            } 
        },{  
            latitude: 54.948813, 
            longitude: 21.704004, 
            html: 'Hello!' 
        }], 
        hideByClick: true 
    }); 
}); 

This is just one example, it has many features to offer like grouping markers and manipulating info windows.

A simpler way of doing it is:

var dictionary = list.GroupBy(it => it.Key).ToDictionary(dict => dict.Key, dict => dict.Select(item => item.value).ToList());

I would solve this problem simply by doing that:

numberText = {
    1: 'one', 2: 'two', 3: 'three', 4: 'four', 5: 'five',
    6: 'six', 7: 'seven', 8: 'eight', 9: 'nine', 10: 'ten',
    11: 'eleven', 12: 'twelve', 13: 'thirteen', 14: 'fourteen',
    15: 'fifteen', 16: 'sixteen', 17: 'seventeen', 18: 'eighteen',
    19: 'nineteen', 20: 'twenty',
    30: 'thirty', 40: 'forty', 50: 'fifty', 60: 'sixty',
    70: 'seventy', 80: 'eighty', 90: 'ninety',
    100: 'hundred', 1000: 'thousand', 1000000: 'million'
}


def numberToEnglishText(n):
    if n == 0:
        return 'zero'
    if n < 0:
        return 'negative ' + numberToEnglishText(-n)

    result = ''

    for num in sorted(numberText.keys(), reverse=True):
        count = int(n/num)

        if (count < 1):
            continue

        if (num >= 100):
            result += numberToEnglishText(count) + ' '

        result += numberText[num]
        n -= count * num
        if (n > 0):
            result += ' '

    return result

You have a number of problems:

• There's a problem with your indentation as others already pointed out.
• There's no need to have nested loops. Just one loop is enough.
• You're using char to mean two different things, but the char variable in the for loop will overwrite the data from the parameter.

This code fixes all these errors:

def count_letters(word, char):
    count = 0
    for c in word:
        if char == c:
            count += 1
    return count

A much more concise way to write this is to use a generator expression:

def count_letters(word, char):
    return sum(char == c for c in word)

Or just use the built-in method count that does this for you:

print 'abcbac'.count('c')

this works for me:

public static class eSound_Def
{
  private static Android.Media.MediaPlayer mpBeep;

  public static void InitSounds( Android.Content.Res.AssetManager Assets )
  {
    mpBeep = new Android.Media.MediaPlayer();

    InitSound_Beep( Assets );
  }

  private static void InitSound_Beep( Android.Content.Res.AssetManager Assets )
  {
    Android.Content.Res.AssetFileDescriptor AFD;

    AFD = Assets.OpenFd( "Sounds/beep-06.mp3" );
    mpBeep.SetDataSource( AFD.FileDescriptor, AFD.StartOffset, AFD.Length );
    AFD.Close();

    mpBeep.Prepare();
    mpBeep.SetVolume( 1f, 1f );
    mpBeep.Looping = false;
  }

  public static void PlaySound_Beep()
  {
    if (mpBeep.IsPlaying == true) 
    {
      mpBeep.Stop();
      mpBeep.Reset();
      InitSound_Beep(); 
    }
    mpBeep.Start();
  }
}

In main activity, on create:

protected override void OnCreate( Bundle savedInstanceState )
{
  base.OnCreate( savedInstanceState );
  SetContentView( Resource.Layout.lmain_activity );
  ...
  eSound_Def.InitSounds( Assets );
  ...
}

how to use in code (on button click):

private void bButton_Click( object sender, EventArgs e )
{
  eSound_Def.PlaySound_Beep();
}

If you are using any layout page then, move script sections from bottom to head section in layout page. bcz, javascript files should be loaded first. This worked for me

Your methods should be (something like)

public static int byteArrayToInt(byte[] b) 
{
    return   b[3] & 0xFF |
            (b[2] & 0xFF) << 8 |
            (b[1] & 0xFF) << 16 |
            (b[0] & 0xFF) << 24;
}

public static byte[] intToByteArray(int a)
{
    return new byte[] {
        (byte) ((a >> 24) & 0xFF),
        (byte) ((a >> 16) & 0xFF),   
        (byte) ((a >> 8) & 0xFF),   
        (byte) (a & 0xFF)
    };
}

These methods were tested with the following code :

Random rand = new Random(System.currentTimeMillis());
byte[] b;
int a, v;
for (int i=0; i<10000000; i++) {
    a = rand.nextInt();
    b = intToByteArray(a);
    v = byteArrayToInt(b);
    if (a != v) {
        System.out.println("ERR! " + a + " != " + Arrays.toString(b) + " != " + v);
    }
}
System.out.println("Done!");

In my case I had an empty line prior a drawable definition in xml. This was braking aapt essentially not allowing to generate R.java .

I use a List of NameValuePair and URLEncodedUtils to create the url string I want.

protected String addLocationToUrl(String url){
    if(!url.endsWith("?"))
        url += "?";

    List<NameValuePair> params = new LinkedList<NameValuePair>();

    if (lat != 0.0 && lon != 0.0){
        params.add(new BasicNameValuePair("lat", String.valueOf(lat)));
        params.add(new BasicNameValuePair("lon", String.valueOf(lon)));
    }

    if (address != null && address.getPostalCode() != null)
        params.add(new BasicNameValuePair("postalCode", address.getPostalCode()));
    if (address != null && address.getCountryCode() != null)
        params.add(new BasicNameValuePair("country",address.getCountryCode()));

    params.add(new BasicNameValuePair("user", agent.uniqueId));

    String paramString = URLEncodedUtils.format(params, "utf-8");

    url += paramString;
    return url;
}

No Go doesn't have a ternary operator, using if/else syntax is the idiomatic way.

Why does Go not have the ?: operator?

There is no ternary testing operation in Go. You may use the following to achieve the same result:

if expr {
    n = trueVal
} else {
    n = falseVal
}

The reason ?: is absent from Go is that the language's designers had seen the operation used too often to create impenetrably complex expressions. The if-else form, although longer, is unquestionably clearer. A language needs only one conditional control flow construct.

This worked for me:

.footer
{
  width: 100%;
  bottom: 0;
  clear: both;
}

$('#mytable tr').each(function() {
    var customerId = $(this).find("td:first").html();    
});

What you are doing is iterating through all the trs in the table, finding the first td in the current tr in the loop, and extracting its inner html.

To select a particular cell, you can reference them with an index:

$('#mytable tr').each(function() {
    var customerId = $(this).find("td").eq(2).html();    
});

In the above code, I will be retrieving the value of the third row (the index is zero-based, so the first cell index would be 0)

Here's how you can do it without jQuery:

var table = document.getElementById('mytable'), 
    rows = table.getElementsByTagName('tr'),
    i, j, cells, customerId;

for (i = 0, j = rows.length; i < j; ++i) {
    cells = rows[i].getElementsByTagName('td');
    if (!cells.length) {
        continue;
    }
    customerId = cells[0].innerHTML;
}

?

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }
                .AddBody(BODY);

var response = Client.Execute(request);

// Handle response errors
HandleResponseErrors(response);

if (Errors.Length == 0)
{ }
else
{ }

Hope this helps! (Although it is a bit late)

To use javascript api,

<script type="text/javascript" src="swfobject.js"></script>
  <div id="ytapiplayer">
    You need Flash player 8+ and JavaScript enabled to view this video.
  </div>

  <script type="text/javascript">

    var params = { allowScriptAccess: "always" };
    var atts = { id: "myytplayer" };
    swfobject.embedSWF("http://www.youtube.com/v/OyHoZhLdgYw?enablejsapi=1&playerapiid=ytplayer&version=3",
                       "ytapiplayer", "425", "356", "8", null, null, params, atts);

  </script>

To play the youtube with the id:

you need to use ++$counter, not $++counter, hence the reason it isn't working..

You must add "include fastcgi.conf" in

location ~ \.$php{
  #......
  include fastcgi.conf;
}

The point about generics is to give compile-time type safety - which means that types need to be known at compile-time.

You can call generic methods with types only known at execution time, but you have to use reflection:

// For non-public methods, you'll need to specify binding flags too
MethodInfo method = GetType().GetMethod("DoesEntityExist")
                             .MakeGenericMethod(new Type[] { t });
method.Invoke(this, new object[] { entityGuid, transaction });

Ick.

Can you make your calling method generic instead, and pass in your type parameter as the type argument, pushing the decision one level higher up the stack?

If you could give us more information about what you're doing, that would help. Sometimes you may need to use reflection as above, but if you pick the right point to do it, you can make sure you only need to do it once, and let everything below that point use the type parameter in a normal way.

If you are developing for Android, Color's method for this is rgb(int, int, int)

So you would do something like

myPaint.setColor(Color.rgb(int, int, int)); 

For retrieving the individual color values you can use the methods for doing so:

Color.red(int color) 
Color.blue(int color) 
Color.green(int color)

May be it look's like this:

Cache

var node = $('.selector')[0];
OR
var node = document.querySelector('.selector');

Set CSS

node.style.setProperty('width', '100px', 'important');

Remove CSS

node.style.removeProperty('width');
OR
node.style.width = '';

The trouble is that you can not return a value from an asynchronous call, like an AJAX request, and expect it to work.

The reason is that the code waiting for the response has already executed by the time the response is received.

The solution to this problem is to run the necessary code inside the success: callback. That way it is accessing the data only when it is available.

function isSession(selector) {
    $.ajax({
        type: "POST",
        url: '/order.html',
        data: ({ issession : 1, selector: selector }),
        dataType: "html",
        success: function(data) {
            // Run the code here that needs
            //    to access the data returned
            return data;
        },
        error: function() {
            alert('Error occured');
        }
    });
}

Another possibility (which is effectively the same thing) is to call a function inside your success: callback that passes the data when it is available.

function isSession(selector) {
    $.ajax({
        type: "POST",
        url: '/order.html',
        data: ({ issession : 1, selector: selector }),
        dataType: "html",
        success: function(data) {
                // Call this function on success
            someFunction( data );
            return data;
        },
        error: function() {
            alert('Error occured');
        }
    });
}

function someFunction( data ) {
    // Do something with your data
}

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.

So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.

Solution:

By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution

See This Demo

They've bundled all the target/build configuration/debugging options stuff into "schemes". The transition guide has a good explanation.

Edit:-

Note vim-airline is gaining some traction as the new vimscript option as powerline has gone python.

Seems powerline is where it is at these days:-

Normal status line

Customised status lines for other plugins (e.g. ctrlp)

This is somewhat related and might help others, I had a corrupt version of some of my plugins so I was able to just delete the entire contents of the plugins folder. Note, all references are still in the package.json and config.xml files to the plugins. So then when I removed and added the Android platform, it re-installed the uncorrupted versions of the plugins and fixed my problem.

I found a way to do it with plain old HTML and JavaScript/jQuery that degrades gracefully. Tested in IE7-10, Safari, Chrome, and FF:

HTML for download link:

<p>Thanks for downloading! If your download doesn't start shortly, 
<a id="downloadLink" href="...yourpdf.pdf" target="_blank" 
type="application/octet-stream" download="yourpdf.pdf">click here</a>.</p>

jQuery (pure JavaScript code would be more verbose) that simulates clicking on link after a small delay:

var delay = 3000;
window.setTimeout(function(){$('#downloadLink')[0].click();},delay);

To make this more robust you could add HTML5 feature detection and if it's not there then use window.open() to open a new window with the file.

This is a method which will work:

import java.awt.image.BufferedImage;
import java.awt.Rectangle;
import java.awt.Color;
import java.awt.Graphics;

public BufferedImage crop(BufferedImage src, Rectangle rect)
{
    BufferedImage dest = new BufferedImage(rect.getWidth(), rect.getHeight(), BufferedImage.TYPE_ARGB_PRE);
    Graphics g = dest.getGraphics();
    g.drawImage(src, 0, 0, rect.getWidth(), rect.getHeight(), rect.getX(), rect.getY(), rect.getX() + rect.getWidth(), rect.getY() + rect.getHeight(), null);
    g.dispose();
    return dest;
}

Of course you have to make your own JComponent:

import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
import java.awt.image.BufferedImage;
import java.awt.Rectangle;
import java.awt.Graphics;
import javax.swing.JComponent;

public class JImageCropComponent extends JComponent implements MouseListener, MouseMotionListener
{
   private BufferedImage img;
   private int x1, y1, x2, y2;

   public JImageCropComponent(BufferedImage img)
   {
       this.img = img;
       this.addMouseListener(this);
       this.addMouseMotionListener(this);
   }

   public void setImage(BufferedImage img)
   {
       this.img = img;
   }

   public BufferedImage getImage()
   {
       return this;
   }

   @Override
   public void paintComponent(Graphics g)
   {
      g.drawImage(img, 0, 0, this);
      if (cropping)
      {
          // Paint the area we are going to crop.
          g.setColor(Color.RED);
          g.drawRect(Math.min(x1, x2), Math.min(y1, y2), Math.max(x1, x2), Math.max(y1, y2));
      }
   }

   @Override
   public void mousePressed(MouseEvent evt)
   {
       this.x1 = evt.getX();
       this.y1 = evt.getY();
   }

   @Override
   public void mouseReleased(MouseEvent evt)
   {
       this.cropping = false;
       // Now we crop the image;
       // This is the method a wrote in the other snipped
       BufferedImage cropped = crop(new Rectangle(Math.min(x1, x2), Math.min(y1, y2), Math.max(x1, x2), Math.max(y1, y2));
       // Now you have the cropped image;
       // You have to choose what you want to do with it
       this.img = cropped;
   }

   @Override
   public void mouseDragged(MouseEvent evt)
   {
       cropping = true;
       this.x2 = evt.getX();
       this.y2 = evt.getY();
   }

   //TODO: Implement the other unused methods from Mouse(Motion)Listener

}

I didn't test it. Maybe there are some mistakes (I'm not sure about all the imports).

You can put the crop(img, rect) method in this class. Hope this helps.

Finally, the latest node.js release v10.3.0 has natively supported fs promises.

const fsPromises = require('fs').promises; // or require('fs/promises') in v10.0.0
fsPromises.writeFile(ASIN + '.json', JSON.stringify(results))
  .then(() => {
    console.log('JSON saved');
  })
  .catch(er => {
    console.log(er);
  });

You can check the official documentation for more details. https://nodejs.org/api/fs.html#fs_fs_promises_api

In SQL you can not have a variable array.
However, the best alternative solution is to use a temporary table.

It is hard to make a good timing, because the performance.dominteractive is miscalulated (anyway an interesting link for timing developers).

When dom is parsed it still may load and execute deferred scripts. And inline scripts waiting for css (css blocking dom) has to be loaded also until DOMContentloaded. So it is not yet parsed?

And we have readystatechange event where we can look at readyState that unfortunately is missing "dom is parsed" that happens somewhere between "loaded" and "interactive".

Everything becomes problematic when even not the Timing API gives us a time when dom stoped parsing HTML and starting The End process. This standard say the first point has to be that "interactive" fires precisely after dom parsed! Both Chrome and FF has implemented it when document has finished loading sometime after it has parsed. They seem to (mis)interpret the standars as parsing continues beyond deferred scripts executed while people misinterpret DOMContentLoaded as something hapen before defered executing and not after. Anyway...

My recommendation for you is to read about? Navigation Timing API. Or go the easy way and choose a oneliner of these, or run all three and look in your browsers console ...

  document.addEventListener('readystatechange', function() { console.log("Fiered '" + document.readyState + "' after " + performance.now() + " ms"); });

  document.addEventListener('DOMContentLoaded', function() { console.log("Fiered DOMContentLoaded after " + performance.now() + " ms"); }, false);

  window.addEventListener('load', function() { console.log("Fiered load after " + performance.now() + " ms"); }, false);

The time is in milliseconds after document started. I have verified with Navigation? Timing API.

To get seconds for exampe from the time you did var ti = performance.now() you can do parseInt(performance.now() - ti) / 1000

Instead of that kind of performance.now() subtractions the code get little shorter by User Timing API where you set marks in your code and measure between marks.

The column in the database is probably a DECIMAL. You should process it as a BigInteger, not an Integer, otherwise you are losing digits. Or else change the column to int.

I think you want to lowercase the checked value? Try:

var jIsHasKids = $('#chkIsHasKids:checked').val().toLowerCase();

or you want to check it, then get its value as lowercase:

var jIsHasKids = $('#chkIsHasKids').attr("checked", true).val().toLowerCase();

unsafe.park is pretty much the same as thread.wait, except that it's using architecture specific code (thus the reason it's 'unsafe'). unsafe is not made available publicly, but is used within java internal libraries where architecture specific code would offer significant optimization benefits. It's used a lot for thread pooling.

So, to answer your question, all the thread is doing is waiting for something, it's not really using any CPU. Considering that your original stack trace shows that you're using a lock I would assume a deadlock is going on in your case.

Yes I know you have almost certainly already solved this issue by now. However, you're one of the top results if someone googles sun.misc.unsafe.park. I figure answering the question may help others trying to understand what this method that seems to be using all their CPU is.

Reason of the error is wrong initialization of the mysqli object. True construction would be like this:

It separates Model and View controlled by a Controller, As far as Model is concerned, Your Models has to follow OO architecture, future enhancements and other maintenance of the code base should be very easy and the code base should be reusable.

Same model can have any no.of views e.g) same info can be shown in as different graphical views. Same view can have different no.of models e.g) different detailed can be shown as a single graph say as a bar graph. This is what is re-usability of both View and Model.

Enhancements in views and other support of new technologies for building the view can be implemented easily.

Guy who is working on view dose not need to know about the underlying Model code base and its architecture, vise versa for the model.

#include<algorithm>
#include<vector>
#include<iostream>
using namespace std;
int main()
{
    vector<int>v1;
    for(int i=0; i<5; i++)
        v1.push_back(i*2);
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];    //02468
    reverse(v1.begin(),v1.end());
    
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];   //86420
}

After insuring that the string "strOutput" has a correct XML structure, you can do this:

Matcher junkMatcher = (Pattern.compile("^([\\W]+)<")).matcher(strOutput);
strOutput = junkMatcher.replaceFirst("<");

If you don't feel like changing your MySQL configuration you could use an SQL profiler like "Neor Profile SQL" http://www.profilesql.com .

I have not used the CDT for eclipse but I do use Eclipse Java for Ubuntu 12.04 and it works wonders.

Just set the height and width where you are adding that logo. I tried and its working fine

You can use the Shiro library's (formerly JSecurity) implementation of what is described by OWASP.

It also looks like the JASYPT library has a similar utility.

You can use the readline module to read from stdin line by line:

var readline = require('readline');
var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  terminal: false
});

rl.on('line', function(line){
    console.log(line);
})

I tried the solutions above and none worked for me out of the box.

However http://www.baeldung.com/httpclient-post-http-request. Line 6 POST Multipart Request worked within seconds

I just ran a Monte-Carlo simulation on both comparators on double heap sort min max and they both came to the same result:

These are the max comparators I have used:

(A) Collections built-in comparator

 PriorityQueue<Integer> heapLow = new PriorityQueue<Integer>(Collections.reverseOrder());

(B) Custom comparator

PriorityQueue<Integer> heapLow = new PriorityQueue<Integer>(new Comparator<Integer>() {
    int compare(Integer lhs, Integer rhs) {
        if (rhs > lhs) return +1;
        if (rhs < lhs) return -1;
        return 0;
    }
});

This was close to working for me. Also had to add:

"changeOrigin": true,
"pathRewrite": {"^/proxy" : ""}

Full proxy.conf.json shown below:

{
    "/proxy/*": {
        "target": "https://url.com",
        "secure": false,
        "changeOrigin": true,
        "logLevel": "debug",
        "pathRewrite": {
            "^/proxy": ""
        }
    }
}

This is because in line

graph(x**3+2*x-4, range(-10, 11))

x is not defined.

The easiest way is to pass the function you want to plot as a string and use eval to evaluate it as an expression.

So your code with minimal modifications will be

import numpy as np  
import matplotlib.pyplot as plt  
def graph(formula, x_range):  
    x = np.array(x_range)  
    y = eval(formula)
    plt.plot(x, y)  
    plt.show()

and you can call it as

graph('x**3+2*x-4', range(-10, 11))

Issue: The Jet OLE DB provider reads a registry key to determine how many rows are to be read to guess the type of the source column. By default, the value for this key is 8. Hence, the provider scans the first 8 rows of the source data to determine the data types for the columns. If any field looks like text and the length of data is more than 255 characters, the column is typed as a memo field. So, if there is no data with a length greater than 255 characters in the first 8 rows of the source, Jet cannot accurately determine the nature of the data type. As the first 8 row length of data in the exported sheet is less than 255 its considering the source length as VARCHAR(255) and unable to read data from the column having more length.

Fix: The solution is just to sort the comment column in descending order. In 2012 onwards we can update the values in Advance tab in the Import wizard.

In MVC5 I'd use, if your model is the datetime

string dt = Model.ToString("dd/MM/yyy"); 

Or if your model contains the property of the datetime

string dt = Model.dateinModel.ToString("dd/MM/yyy"); 

Here's the official meaning of the Formats:

I would use a for loop to iterate over the lines in the text file:

for line in my_text:
    outputfile.writelines(data_parser(line, reps))

If you want to read the file line-by-line instead of loading the whole thing at the start of the script you could do something like this:

inputfile = open('test.dat')
outputfile = open('test.csv', 'w')

# sample text string, just for demonstration to let you know how the data looks like
# my_text = '"2012-06-23 03:09:13.23",4323584,-1.911224,-0.4657288,-0.1166382,-0.24823,0.256485,"NAN",-0.3489428,-0.130449,-0.2440527,-0.2942413,0.04944348,0.4337797,-1.105218,-1.201882,-0.5962594,-0.586636'

# dictionary definition 0-, 1- etc. are there to parse the date block delimited with dashes, and make sure the negative numbers are not effected
reps = {'"NAN"':'NAN', '"':'', '0-':'0,','1-':'1,','2-':'2,','3-':'3,','4-':'4,','5-':'5,','6-':'6,','7-':'7,','8-':'8,','9-':'9,', ' ':',', ':':',' }

for i in range(4): inputfile.next() # skip first four lines
for line in inputfile:
    outputfile.writelines(data_parser(line, reps))

inputfile.close()
outputfile.close()

It works by same principle of anonymous inner class where we can instantiate an interface without actually defining a class :

Ref: https://www.geeksforgeeks.org/anonymous-inner-class-java/

I use this script:

#!/bin/bash
topics=`kafka-topics --list --zookeeper zookeeper:2181`
for t in $topics; do 
    for p in retention.ms retention.bytes segment.ms segment.bytes; do
        kafka-topics --zookeeper zookeeper:2181 --alter --topic $t --config ${p}=100
    done
done
sleep 60
for t in $topics; do 
    for p in retention.ms retention.bytes segment.ms segment.bytes; do
        kafka-topics --zookeeper zookeeper:2181 --alter --topic $t --delete-config ${p}
    done
done

What i may add here is how to make it work together with DiffUtil and ListAdapter

You may note that calling recyclerView.scrollToPosition(pos) or (recyclerView.layoutManager as LinearLayoutManager).scrollToPositionWithOffset(pos, offset) wouldn't work if called straight after adapter.submitList. It is because the differ looks for changes in a background thread and then asynchronously notifies adapter about changes. On a SO i have seen several wrong answers with unnecessary delays & etc to solve this.

To handle the situation properly the submitList has a callback which is invoked when changes have applied.

So the proper kotlin implementations in this case are:

//memorise target item here and a scroll offset if needed
adapter.submitList(items) { 
    val pos = /* here you may find a new position of the item or just use just a static position. It depends on your case */
    recyclerView.scrollToPosition(pos) 
}
//or
adapter.submitList(items) { recyclerView.smoothScrollToPosition(pos) }
//or etc
adapter.submitList(items) { (recyclerView.layoutManager as LinearLayoutManager).scrollToPositionWithOffset(pos, offset) }

Inspired by writing this answer, I ended up later expanding and writing a blog post going over this in careful detail. I recommend checking that out if you want to develop a deeper understanding of how to think about this problem--I try to explain it piece by piece, and also give a JSperf comparison at the end, going over speed considerations.

That said, The tl;dr is this: To accomplish what you're asking for (filtering and mapping within one function call), you would use Array.reduce().

However, the more readable and (less importantly) usually significantly faster² approach is to just use filter and map chained together:

[1,2,3].filter(num => num > 2).map(num => num * 2)

What follows is a description of how Array.reduce() works, and how it can be used to accomplish filter and map in one iteration. Again, if this is too condensed, I highly recommend seeing the blog post linked above, which is a much more friendly intro with clear examples and progression.

You give reduce an argument that is a (usually anonymous) function.

That anonymous function takes two parameters--one (like the anonymous functions passed in to map/filter/forEach) is the iteratee to be operated on. There is another argument for the anonymous function passed to reduce, however, that those functions do not accept, and that is the value that will be passed along between function calls, often referred to as the memo.

Note that while Array.filter() takes only one argument (a function), Array.reduce() also takes an important (though optional) second argument: an initial value for 'memo' that will be passed into that anonymous function as its first argument, and subsequently can be mutated and passed along between function calls. (If it is not supplied, then 'memo' in the first anonymous function call will by default be the first iteratee, and the 'iteratee' argument will actually be the second value in the array)

In our case, we'll pass in an empty array to start, and then choose whether to inject our iteratee into our array or not based on our function--this is the filtering process.

Finally, we'll return our 'array in progress' on each anonymous function call, and reduce will take that return value and pass it as an argument (called memo) to its next function call.

This allows filter and map to happen in one iteration, cutting down our number of required iterations in half--just doing twice as much work each iteration, though, so nothing is really saved other than function calls, which are not so expensive in javascript.

For a more complete explanation, refer to MDN docs (or to my post referenced at the beginning of this answer).

Basic example of a Reduce call:

let array = [1,2,3];
const initialMemo = [];

array = array.reduce((memo, iteratee) => {
    // if condition is our filter
    if (iteratee > 1) {
        // what happens inside the filter is the map
        memo.push(iteratee * 2); 
    }

    // this return value will be passed in as the 'memo' argument
    // to the next call of this function, and this function will have
    // every element passed into it at some point.
    return memo; 
}, initialMemo)

console.log(array) // [4,6], equivalent to [(2 * 2), (3 * 2)]

more succinct version:

[1,2,3].reduce((memo, value) => value > 1 ? memo.concat(value * 2) : memo, [])

Notice that the first iteratee was not greater than one, and so was filtered. Also note the initialMemo, named just to make its existence clear and draw attention to it. Once again, it is passed in as 'memo' to the first anonymous function call, and then the returned value of the anonymous function is passed in as the 'memo' argument to the next function.

Another example of the classic use case for memo would be returning the smallest or largest number in an array. Example:

[7,4,1,99,57,2,1,100].reduce((memo, val) => memo > val ? memo : val)
// ^this would return the largest number in the list.

An example of how to write your own reduce function (this often helps understanding functions like these, I find):

test_arr = [];

// we accept an anonymous function, and an optional 'initial memo' value.
test_arr.my_reducer = function(reduceFunc, initialMemo) {
    // if we did not pass in a second argument, then our first memo value 
    // will be whatever is in index zero. (Otherwise, it will 
    // be that second argument.)
    const initialMemoIsIndexZero = arguments.length < 2;

    // here we use that logic to set the memo value accordingly.
    let memo = initialMemoIsIndexZero ? this[0] : initialMemo;

    // here we use that same boolean to decide whether the first
    // value we pass in as iteratee is either the first or second
    // element
    const initialIteratee = initialMemoIsIndexZero ? 1 : 0;

    for (var i = initialIteratee; i < this.length; i++) {
        // memo is either the argument passed in above, or the 
        // first item in the list. initialIteratee is either the
        // first item in the list, or the second item in the list.
           memo = reduceFunc(memo, this[i]);
        // or, more technically complete, give access to base array
        // and index to the reducer as well:
        // memo = reduceFunc(memo, this[i], i, this);
    }

    // after we've compressed the array into a single value,
    // we return it.
    return memo;
}

The real implementation allows access to things like the index, for example, but I hope this helps you get an uncomplicated feel for the gist of it.

While using backticks or popen is often what you really want, it doesn't actually answer the question asked. There may be valid reasons for capturing system output (maybe for automated testing). A little Googling turned up an answer I thought I would post here for the benefit of others.

Since I needed this for testing my example uses a block setup to capture the standard output since the actual system call is buried in the code being tested:

require 'tempfile'

def capture_stdout
  stdout = $stdout.dup
  Tempfile.open 'stdout-redirect' do |temp|
    $stdout.reopen temp.path, 'w+'
    yield if block_given?
    $stdout.reopen stdout
    temp.read
  end
end

This method captures any output in the given block using a tempfile to store the actual data. Example usage:

captured_content = capture_stdout do
  system 'echo foo'
end
puts captured_content

You can replace the system call with anything that internally calls system. You could also use a similar method to capture stderr if you wanted.

This did it for me...

//trim message to 100 characters, regardless of where it cuts off
$msgTrimmed = mb_substr($var,0,100);

//find the index of the last space in the trimmed message
$lastSpace = strrpos($msgTrimmed, ' ', 0);

//now trim the message at the last space so we don't cut it off in the middle of a word
echo mb_substr($msgTrimmed,0,$lastSpace)

Based on the docs, xhr Ajax event would fire when an Ajax request is completed. So you can do something like this:

let data_table = $('#example-table').dataTable({
        ajax: "data.json"
    });

data_table.on('xhr.dt', function ( e, settings, json, xhr ) {
        // Do some staff here...
        $('#status').html( json.status );
    } )

function to check undefined and null objects

function elementCheck(objarray, callback) {
        var list_undefined = "";
        async.forEachOf(objarray, function (item, key, next_key) {
            console.log("item----->", item);
            console.log("key----->", key);
            if (item == undefined || item == '') {
                list_undefined = list_undefined + "" + key + "!!  ";
                next_key(null);
            } else {
                next_key(null);
            }
        }, function (next_key) {
            callback(list_undefined);
        })
    }

here is an easy way to check whether object sent is contain undefined or null

var objarray={
"passenger_id":"59b64a2ad328b62e41f9050d",
"started_ride":"1",
"bus_id":"59b8f920e6f7b87b855393ca",
"route_id":"59b1333c36a6c342e132f5d5",
"start_location":"",
"stop_location":""
}
elementCheck(objarray,function(list){
console.log("list");
)

You can also use Prototype's Object.inspect() method, which "Returns the debug-oriented string representation of the object".

http://api.prototypejs.org/language/Object/inspect/

You don't need to convert it. List<T> implements the IEnumerable<T> interface so it is already an enumerable.

This means that it is perfectly fine to have the following:

public IEnumerable<Book> GetBooks()
{
    List<Book> books = FetchEmFromSomewhere();    
    return books;
}

as well as:

public void ProcessBooks(IEnumerable<Book> books)
{
    // do something with those books
}

which could be invoked:

List<Book> books = FetchEmFromSomewhere();    
ProcessBooks(books);

Both of your examples should behave pretty much the same.

A value returned inside a then() handler becomes the resolution value of the promise returned from that then(). If the value returned inside the .then is a promise, the promise returned by then() will "adopt the state" of that promise and resolve/reject just as the returned promise does.

In your first example, you return "bbb" in the first then() handler, so "bbb" is passed into the next then() handler.

In your second example, you return a promise that is immediately resolved with the value "bbb", so "bbb" is passed into the next then() handler. (The Promise.resolve() here is extraneous).

The outcome is the same.

If you can show us an example that actually exhibits different behavior, we can tell you why that is happening.

You can also try this if you are on linux:

system("rm -r path");

The answer proposed by others:

for line in sys.stdin:
  print line

is very simple and pythonic, but it must be noted that the script will wait until EOF before starting to iterate on the lines of input.

This means that tail -f error_log | myscript.py will not process lines as expected.

The correct script for such a use case would be:

while 1:
    try:
        line = sys.stdin.readline()
    except KeyboardInterrupt:
        break

    if not line:
        break

    print line

UPDATE
From the comments it has been cleared that on python 2 only there might be buffering involved, so that you end up waiting for the buffer to fill or EOF before the print call is issued.

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

.NET has spoiled us :) Your declaration is not valid for VBA.

Only constants can be given a value upon application load. You declare them like so:

Public Const APOSTROPHE_KEYCODE = 222

Here's a sample declaration from one of my vba projects:

If you're looking for something where you declare a public variable and then want to initialize its value, you need to create a Workbook_Open sub and do your initialization there. Example:

Private Sub Workbook_Open()
  Dim iAnswer As Integer

  InitializeListSheetDataColumns_S
  HideAllMonths_S

  If sheetSetupInfo.Range("D6").Value = "Enter Facility Name" Then
    iAnswer = MsgBox("It appears you have not yet set up this workbook.  Would you like to do so now?", vbYesNo)
    If iAnswer = vbYes Then
      sheetSetupInfo.Activate
      sheetSetupInfo.Range("D6").Select
      Exit Sub
    End If
  End If

  Application.Calculation = xlCalculationAutomatic
  sheetGeneralInfo.Activate
  Load frmInfoSheet
  frmInfoSheet.Show


End Sub

Make sure you declare the sub in the Workbook Object itself:

int sum = 0;
for(int i = 0; i < A.length; i++){
  sum += A[i];
}

In fact it is possible using Symbols and Proxies. You use the symbols in the class scope and set two traps in a proxy: one for the class prototype so that the Reflect.ownKeys(instance) or Object.getOwnPropertySymbols doesn't give your symbols away, the other one is for the constructor itself so when new ClassName(attrs) is called, the instance returned will be intercepted and have the own properties symbols blocked. Here's the code:

const Human = (function() {_x000D_
  const pet = Symbol();_x000D_
  const greet = Symbol();_x000D_
_x000D_
  const Human = privatizeSymbolsInFn(function(name) {_x000D_
    this.name = name; // public_x000D_
    this[pet] = 'dog'; // private _x000D_
  });_x000D_
_x000D_
  Human.prototype = privatizeSymbolsInObj({_x000D_
    [greet]() { // private_x000D_
      return 'Hi there!';_x000D_
    },_x000D_
    revealSecrets() {_x000D_
      console.log(this[greet]() + ` The pet is a ${this[pet]}`);_x000D_
    }_x000D_
  });_x000D_
_x000D_
  return Human;_x000D_
})();_x000D_
_x000D_
const bob = new Human('Bob');_x000D_
_x000D_
console.assert(bob instanceof Human);_x000D_
console.assert(Reflect.ownKeys(bob).length === 1) // only ['name']_x000D_
console.assert(Reflect.ownKeys(Human.prototype).length === 1 ) // only ['revealSecrets']_x000D_
_x000D_
_x000D_
// Setting up the traps inside proxies:_x000D_
function privatizeSymbolsInObj(target) { _x000D_
  return new Proxy(target, { ownKeys: Object.getOwnPropertyNames });_x000D_
}_x000D_
_x000D_
function privatizeSymbolsInFn(Class) {_x000D_
  function construct(TargetClass, argsList) {_x000D_
    const instance = new TargetClass(...argsList);_x000D_
    return privatizeSymbolsInObj(instance);_x000D_
  }_x000D_
  return new Proxy(Class, { construct });_x000D_
}

Reflect.ownKeys() works like so: Object.getOwnPropertyNames(myObj).concat(Object.getOwnPropertySymbols(myObj)) that's why we need a trap for these objects.

Neither code is always better. They do different things, so they are good at different things.

InvariantCultureIgnoreCase uses comparison rules based on english, but without any regional variations. This is good for a neutral comparison that still takes into account some linguistic aspects.

OrdinalIgnoreCase compares the character codes without cultural aspects. This is good for exact comparisons, like login names, but not for sorting strings with unusual characters like é or ö. This is also faster because there are no extra rules to apply before comparing.

Right click on the web page you want to use as the default page and choose "Set as Start Page" whenever you run the web application from Visual Studio, it will open the selected page.

If you didn't care about performance, you could try:

a.Any(item => b.Contains(item))
// or, as in the column using a method group
a.Any(b.Contains)

But I would try this first:

a.Intersect(b).Any()

I spent measurements (100000 iterations), what fastest way to glue an associative array?

Objective: To obtain a line of 1,000 items, in this format: "key:value,key2:value2"

We have array (for example):

$array = [
    'test0' => 344,
    'test1' => 235,
    'test2' => 876,
    ...
];

Test number one:

Use http_build_query and str_replace:

str_replace('=', ':', http_build_query($array, null, ','));

Average time to implode 1000 elements: 0.00012930955084904

Test number two:

Use array_map and implode:

implode(',', array_map(
        function ($v, $k) {
            return $k.':'.$v;
        },
        $array,
        array_keys($array)
    ));

Average time to implode 1000 elements: 0.0004890081976675

Test number three:

Use array_walk and implode:

array_walk($array,
        function (&$v, $k) {
            $v = $k.':'.$v;
        }
    );
implode(',', $array);

Average time to implode 1000 elements: 0.0003874126245348

Test number four:

Use foreach:

    $str = '';
    foreach($array as $key=>$item) {
        $str .= $key.':'.$item.',';
    }
    rtrim($str, ',');

Average time to implode 1000 elements: 0.00026632803902445

I can conclude that the best way to glue the array - use http_build_query and str_replace

I liked the "START /W" answer, though for my situation I found something even more basic. My processes were console applications. And in my ignorance I thought I would need something special in BAT syntax to make sure that the 1st one completed before the 2nd one started. However BAT appears to make a distinction between console apps and windows apps, and it executes them a little differently. The OP shows that window apps will get launched as an asynchronous call from BAT. But for console apps, that are invoked synchronously, inside the same command window as the BAT itself is running in.

For me it was actually better not to use "START /W", because everything could run inside one command window. The annoying thing about "START /W" is that it will spawn a new command window to execute your console application in.

Environment:Linux Error: "jenkins Failed to connect to repository : Error performing command: git ls-remote -h"

Solution : if repository URL and credential configured correctly ,problem on git installion and config a) make sure git installed on your linux machine. if git not installed , install it ("sudo yum install git") b) Goto to -> Manage Jenkins -> Global Tool Configuration ->Git->Path to Git executable make sure "git" command present.

Use set -e

#!/bin/bash

set -e

/bin/command-that-fails
/bin/command-that-fails2

The script will terminate after the first line that fails (returns nonzero exit code). In this case, command-that-fails2 will not run.

If you were to check the return status of every single command, your script would look like this:

#!/bin/bash

# I'm assuming you're using make

cd /project-dir
make
if [[ $? -ne 0 ]] ; then
    exit 1
fi

cd /project-dir2
make
if [[ $? -ne 0 ]] ; then
    exit 1
fi

With set -e it would look like:

#!/bin/bash

set -e

cd /project-dir
make

cd /project-dir2
make

Any command that fails will cause the entire script to fail and return an exit status you can check with $?. If your script is very long or you're building a lot of stuff it's going to get pretty ugly if you add return status checks everywhere.

1. Wrap the textbox inside asp:Panel tags

2. Hide a Button that has a click event that does what you want done and give the <asp:panel> a DefaultButton Attribute with the ID of the Hidden Button.

<asp:Panel runat="server" DefaultButton="Button1">
   <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>    
   <asp:Button ID="Button1" runat="server" style="display:none" OnClick="Button1_Click" />
</asp:Panel>

commons-collections4-x.x.jar definitely solve this problem but Apache has removed the Interface ListValuedMap from commons-Collections4-4.0.jar so use updated version 4.1 it has the required classes and Interfaces.

@media queries serve this purpose. Here's an example:

@media only screen and (max-width: 991px) and (min-width: 769px){
 /* CSS that should be displayed if width is equal to or less than 991px and larger 
  than 768px goes here */
}

@media only screen and (max-width: 991px){
 /* CSS that should be displayed if width is equal to or less than 991px goes here */
}

A bit late to the game but if I'm understanding your needs correctly this will help people with the same issue.

Two solutions with the same first step: First navigate to the location you keep your scripts in and copy the filepath to that directory.

First Solution:

• Click "Start"
• Right-click "Computer" (or "My Computer)
• Click "Properties"
• On the left, click "Advanced System Settings"
• Click "Environment Variables"
• In the "System Variables" Box, scroll down and select "PATH"
• Click "Edit"
• In the "Variable Value" field, scroll all the way to the right
• If there isn't a semi-colon (;) there yet, add it.
• Paste in the filepath you copied earlier.
• End with a semi-colon.
• Click "OK"
• Click "OK" again
• Click "OK" one last time

You can now use any of your scripts as if you were already that folder.

Second Solution: (can easily be paired with the first for extra usefulness)

On your desktop create a batch file with the following content.

@echo off
cmd /k cd "C:\your\file\path"

This will open a command window like what you tried to do.

OK, first of all I'm not sure how it works when you create a div using (document.createElement('div')), so I might be wrong now, but wouldn't it be possible to use the :target pseudo class selector for this?

If you look at the code below, you can se I've used a link to target the div, but in your case it might be possible to target #new from the script instead and that way make the div fade in without user interaction, or am I thinking wrong?

Here's the code for my example:

HTML

<a href="#new">Click</a> 
<div id="new">
    Fade in ... 
</div>

CSS

#new {
    width: 100px;
    height: 100px;
    border: 1px solid #000000;
    opacity: 0;    
}


#new:target {
    -webkit-transition: opacity 2.0s ease-in;
       -moz-transition: opacity 2.0s ease-in;
         -o-transition: opacity 2.0s ease-in;
                                  opacity: 1;
}

... and here's a jsFiddle

There are multiple false assumptions you're making here - First, function belong to a class and not to an instance, meaning the actual function involved is the same for any two instances of a class. Second, default parameters are evaluated at compile time and are constant (as in, a constant object reference - if the parameter is a mutable object you can change it). Thus you cannot access self in a default parameter and will never be able to.

Thinking about a Map with 2 keys immediately compelled me to use a user-defined key, and that would probably be a Class. Following is the key Class:

public class MapKey {
    private Object key1;
    private Object key2;

    public Object getKey1() {
        return key1;
    }

    public void setKey1(Object key1) {
        this.key1 = key1;
    }

    public Object getKey2() {
        return key2;
    }

    public void setKey2(Object key2) {
        this.key2 = key2;
    }
}


// Create first map entry with key <A,B>.
        MapKey mapKey1 = new MapKey();
        mapKey1.setKey1("A");
        mapKey1.setKey2("B");

You can get entire post body into a POJO. Following is something similar

@RequestMapping(
    value = { "/api/pojo/edit" }, 
    method = RequestMethod.POST, 
    produces = "application/json", 
    consumes = ["application/json"])
@ResponseBody
public Boolean editWinner( @RequestBody Pojo pojo) { 

Where each field in Pojo (Including getter/setters) should match the Json request object that the controller receives..

Above answers assume that UTF8 encoding can safely be used - this one is specifically targetted for Windows.

The Windows console normaly uses CP850 encoding and not utf-8, so if you try to use a source file utf8-encoded, you get those 2 (incorrect) characters -¦ instead of a degree °.

Demonstration (using python 2.7 in a windows console):

deg = u'\xb0`  # utf code for degree
print deg.encode('utf8')

effectively outputs -¦.

Fix: just force the correct encoding (or better use unicode):

local_encoding = 'cp850'    # adapt for other encodings
deg = u'\xb0'.encode(local_encoding)
print deg

or if you use a source file that explicitely defines an encoding:

# -*- coding: utf-8 -*-
local_encoding = 'cp850'  # adapt for other encodings
print " The current temperature in the country/city you've entered is " + temp_in_county_or_city + "°C.".decode('utf8').encode(local_encoding)

If you're checking for explicit types, why are you declaring those variables as T's?

T HowToCast<T>(T t)
{
    if (typeof(T) == typeof(string))
    {
        var newT1 = "some text";
        var newT2 = t;  //this builds but I'm not sure what it does under the hood.
        var newT3 = t.ToString();  //for sure the string you want.
    }

    return t;
}

Defining a custom __call__() method in the meta-class allows the class's instance to be called as a function, not always modifying the instance itself.

In [1]: class A:
   ...:     def __init__(self):
   ...:         print "init"
   ...:         
   ...:     def __call__(self):
   ...:         print "call"
   ...:         
   ...:         

In [2]: a = A()
init

In [3]: a()
call

I would do:

select DBMS_CRYPTO.HASH(rawtohex('foo') ,2) from dual;

output:

DBMS_CRYPTO.HASH(RAWTOHEX('FOO'),2)

I wrote this script to search for all .mkv files recursively renaming found files to .avi. You can customize it to your neeeds. I've added some other things such as getting file directory, extension, file name from a file path just incase you need to refer to something in the future.

find . -type f -name "*.mkv" | while read fp; do 
fd=$(dirname "${fp}");
fn=$(basename "${fp}");
ext="${fn##*.}";
f="${fn%.*}";
new_fp="${fd}/${f}.avi"
mv -v "$fp" "$new_fp" 
done;

Events bubble to the highest point in the DOM at which a click event has been attached. So in your example, even if you didn't have any other explicitly clickable elements in the div, every child element of the div would bubble their click event up the DOM to until the DIV's click event handler catches it.

There are two solutions to this is to check to see who actually originated the event. jQuery passes an eventargs object along with the event:

$("#clickable").click(function(e) {
    var senderElement = e.target;
    // Check if sender is the <div> element e.g.
    // if($(e.target).is("div")) {
    window.location = url;
    return true;
});

You can also attach a click event handler to your links which tell them to stop event bubbling after their own handler executes:

$("#clickable a").click(function(e) {
   // Do something
   e.stopPropagation();
});

SOLUTION 2019 (Windows, Android Studio 3.3, gradle 4.10):

This solution only works if "Remember password" checkbox was previously marked.

First of all taskArtifacts.bin don't exist for this version of gradle and idea.log shows asterisks for passwords. This was old days solutions that doesn't worked to me.

Where I found the clear text passwords: C:\Users\{username}\AndroidStudioProjects\{project}\app\build\intermediates\signing_config\release\out\signing-config.json

Keys: mStorePassword and mKeyPassword.

I really hope it helps someone else.

I just did this for fun

    >>> s = 'a,b,c,d'
    >>> [item[::-1] for item in s[::-1].split(',', 1)][::-1]
    ['a,b,c', 'd']

Caution: Refer to the first comment in below where this answer can go wrong.

You need to have cl.exe (the Microsoft C Compiler) installed on your computer and in your PATH. PATH is an environment variable that tells Windows where to find executable files.

First, ensure the C++ build tools for Visual Studio are installed. You can download Build Tools for Visual Studio separately from the Visual Studio downloads page, then choose C++ build tools from the installer. If you already have Visual Studio, you can also install Desktop development with C++ from the Visual Studio Installer which you should have in Start Menu.

Then, instead of the normal Command Prompt or PowerShell, use one of the special command prompts in the Visual Studio folder in Start Menu. For 32-bit Python, you're probably looking for x86 Native Tools Command Prompt. This sets up PATH automatically, so that cl.exe can be found.

Just to clarify -- as noted above when rebasing the sense is reversed, so if you see

<<<<<<< HEAD
        foo = 12;
=======
        foo = 22;
>>>>>>> [your commit message]

Resolve using 'mine' -> foo = 12

Resolve using 'theirs' -> foo = 22

An array is a structure with a certain size. You can use dynamic arrays in vba that you can shrink or grow using ReDim but you can't remove elements in the middle. It's not clear from your sample how your array functionally works or how you determine the index position (eachHdr) but you basically have 3 options

(A) Write a custom 'delete' function for your array like (untested)

Public Sub DeleteElementAt(Byval index As Integer, Byref prLst as Variant)
       Dim i As Integer

        ' Move all element back one position
        For i = index + 1 To UBound(prLst)
            prLst(i - 1) = prLst(i)
        Next

        ' Shrink the array by one, removing the last one
        ReDim Preserve prLst(Len(prLst) - 1)
End Sub

(B) Simply set a 'dummy' value as the value instead of actually deleting the element

If prLst(eachHdr) = "0" Then        
   prLst(eachHdr) = "n/a"
End If

(C) Stop using an array and change it into a VBA.Collection. A collection is a (unique)key/value pair structure where you can freely add or delete elements from

Dim prLst As New Collection

The Chosen plugin does not automatically update its list of options when the OPTION elements in the DOM change. You have to send it an event to trigger the update:

Pre Chosen 1.0: $('.chzn-select').trigger("liszt:updated");

Chosen 1.0 $('.chosen-select').trigger("chosen:updated");

If you are dynamically managing the OPTION elements, then you'll have to do this whenever the OPTIONs change. The way you do this will vary - in AngularJS, try something like this:

$scope.$watch(
  function() {
    return element.find('option').map(function() { return this.value }).get().join();
  }, 
  function() {
    element.trigger('liszt:updated');
  }
 }

I got a MD5 hash with different results for both key and certificate.

This says it all. You have a mismatch between your key and certificate.

The modulus should match. Make sure you have correct key.

== and != work on object identity. While the two Strings have the same value, they are actually two different objects.

use !"success".equals(statusCheck) instead.

For Angular 2 - 5 refer the article Multiple Environment in angular

For Angular 6 use ng serve --configuration=dev

Note: Refer the same article for angular 6 as well. But wherever you find --env instead use --configuration. That's works well for angular 6.

The best way in browsers that support it, is to send the file as a Blob, or using FormData if you want a multipart form. You do not need a FileReader for that. This is both simpler and more efficient than trying to read the data.

If you specifically want to send it as multipart/form-data, you can use a FormData object:

var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
var formData = new FormData();
// This should automatically set the file name and type.
formData.append("file", file);
// Sending FormData automatically sets the Content-Type header to multipart/form-data
xmlHttpRequest.send(formData);

You can also send the data directly, instead of using multipart/form-data. See the documentation. Of course, this will need a server-side change as well.

// file is an instance of File, e.g. from a file input.
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);

xmlHttpRequest.setRequestHeader("Content-Type", file.type);

// Send the binary data.
// Since a File is a Blob, we can send it directly.
xmlHttpRequest.send(file);

For browser support, see: http://caniuse.com/#feat=xhr2 (most browsers, including IE 10+).

I think you should only throw an exception when there's nothing you can do to get out of your current state. For example if you are allocating memory and there isn't any to allocate. In the cases you mention you can clearly recover from those states and can return an error code back to your caller accordingly.

You will see plenty of advice, including in answers to this question, that you should throw exceptions only in "exceptional" circumstances. That seems superficially reasonable, but is flawed advice, because it replaces one question ("when should I throw an exception") with another subjective question ("what is exceptional"). Instead, follow the advice of Herb Sutter (for C++, available in the Dr Dobbs article When and How to Use Exceptions, and also in his book with Andrei Alexandrescu, C++ Coding Standards): throw an exception if, and only if

• a precondition is not met (which typically makes one of the following impossible) or
• the alternative would fail to meet a post-condition or
• the alternative would fail to maintain an invariant.

Why is this better? Doesn't it replace the question with several questions about preconditions, postconditions and invariants? This is better for several connected reasons.

• Preconditions, postconditions and invariants are design characteristics of our program (its internal API), whereas the decision to throw is an implementation detail. It forces us to bear in mind that we must consider the design and its implementation separately, and our job while implementing a method is to produce something that satisfies the design constraints.
• It forces us to think in terms of preconditions, postconditions and invariants, which are the only assumptions that callers of our method should make, and are expressed precisely, enabling loose coupling between the components of our program.
• That loose coupling then allows us to refactor the implementation, if necessary.
• The post-conditions and invariants are testable; it results in code that can be easily unit tested, because the post-conditions are predicates our unit-test code can check (assert).
• Thinking in terms of post-conditions naturally produces a design that has success as a post-condition, which is the natural style for using exceptions. The normal ("happy") execution path of your program is laid out linearly, with all the error handling code moved to the catch clauses.

<a href="@Url.Action("DeleteBlog")" class="btn btn-sm btn-danger" onclick="return confirm ('Are you sure want to delete blog?');">

Something like this should work (untested code warning):

<?php

$html = '<p style="asd">qwe</p><br /><p class="qwe">qweqweqwe</p>';

$domd = new DOMDocument();
libxml_use_internal_errors(true);
$domd->loadHTML($html);
libxml_use_internal_errors(false);

$domx = new DOMXPath($domd);
$items = $domx->query("//p[@style]");

foreach($items as $item) {
  $item->removeAttribute("style");
}

echo $domd->saveHTML();

This can be achieved through LINQ with grouping, here a list of items pointed as a data source to the actual grid view. Sample pseudo code which could help coding the actual.

var tabelDetails =(from li in dc.My_table
    join m in dc.Table_One on li.ID equals m.ID
    join c in dc.Table_two on li.OtherID equals c.ID
    where //Condition
group new { m, li, c } by new
{
    m.ID,
    m.Name
} into g
select new
{
    g.Key.ID,
    Name = g.Key.FullName,
    sponsorBonus= g.Where(s => s.c.Name == "sponsorBonus").Count(),
    pairingBonus = g.Where(s => s.c.Name == "pairingBonus").Count(),
    staticBonus = g.Where(s => s.c.Name == "staticBonus").Count(),   
    leftBonus = g.Where(s => s.c.Name == "leftBonus").Count(),  
    rightBonus = g.Where(s => s.c.Name == "rightBonus").Count(),  
    Total = g.Count()  //Row wise Total
}).OrderBy(t => t.Name).ToList();

tabelDetails.Insert(tabelDetails.Count(), new  //This data will be the last row of the grid
{
    Name = "Total",  //Column wise total
    sponsorBonus = tabelDetails.Sum(s => s.sponsorBonus),
    pairingBonus = tabelDetails.Sum(s => s.pairingBonus),
    staticBonus = tabelDetails.Sum(s => s.staticBonus),
    leftBonus = tabelDetails.Sum(s => s.leftBonus),
    rightBonus = tabelDetails.Sum(s => s.rightBonus ),
    Total = tabelDetails.Sum(s => s.Total)
});

In your example, a browser isn't "supposed" to do anything. The HTML is invalid. Either error recovery is triggered, or the parser makes of it as it will.

In a valid instance, multiple stylesheets are just treated as appearing one after the other, the cascade is calculated as normal.

I wanted to ask the same question. Here is my current solution to obtain a string like this: 2013-02-07 09:24:40.749355372 I am not sure if there is a more straight forward solution than this, but at least the string format is freely configurable with this approach.

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

#define NANO 1000000000L

// buf needs to store 30 characters
int timespec2str(char *buf, uint len, struct timespec *ts) {
    int ret;
    struct tm t;

    tzset();
    if (localtime_r(&(ts->tv_sec), &t) == NULL)
        return 1;

    ret = strftime(buf, len, "%F %T", &t);
    if (ret == 0)
        return 2;
    len -= ret - 1;

    ret = snprintf(&buf[strlen(buf)], len, ".%09ld", ts->tv_nsec);
    if (ret >= len)
        return 3;

    return 0;
}

int main(int argc, char **argv) {
    clockid_t clk_id = CLOCK_REALTIME;
    const uint TIME_FMT = strlen("2012-12-31 12:59:59.123456789") + 1;
    char timestr[TIME_FMT];

    struct timespec ts, res;
    clock_getres(clk_id, &res);
    clock_gettime(clk_id, &ts);

    if (timespec2str(timestr, sizeof(timestr), &ts) != 0) {
        printf("timespec2str failed!\n");
        return EXIT_FAILURE;
    } else {
        unsigned long resol = res.tv_sec * NANO + res.tv_nsec;
        printf("CLOCK_REALTIME: res=%ld ns, time=%s\n", resol, timestr);
        return EXIT_SUCCESS;
    }
}

output:

gcc mwe.c -lrt 
$ ./a.out 
CLOCK_REALTIME: res=1 ns, time=2013-02-07 13:41:17.994326501

Generally speaking, don't. If you are nesting "ifs" and breaking from them, you are doing it wrong.

However, if you must:

if condition_a:
   def condition_a_fun():
       do_stuff()
       if we_wanna_escape:
           return
   condition_a_fun()
if condition_b:
   def condition_b_fun():
       do_more_stuff()
       if we_wanna_get_out_again:
           return
   condition_b_fun()

Note, the functions don't HAVE to be declared in the if statement, they can be declared in advance ;) This would be a better choice, since it will avoid needing to refactor out an ugly if/then later on.

start "" ExeToExecute

method does not work for me in the case of Xilinx xsdk, because as pointed out by @jeb in the comments below it is actaully a bat file.

so what does not work de-facto is

start "" BatToExecute

I am trying to open xsdk like that and it opens a separate cmd that needs to be closed and xsdk can run on its own

Before launching xsdk I run (source) the Env / Paths (with settings64.bat) so that xsdk.bat command gets recognized (simply as xsdk, withoitu the .bat)

what works with .bat

call BatToExecute

If you want to keep the row with the lowest id value:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MIN(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

If you want the id value that is the highest:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MAX(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

The subquery in a subquery is necessary for MySQL, or you'll get a 1093 error.

Pure CSS solution:

Use the :first-line pseudo-class.

display:block;
Width:40-100px; /* just enough for one word, depends on font size */
Overflow:visible; /* so longer words don't get clipped.*/
float:left; /* so it will flow with the paragraph. */
position:relative; /* for typeset adjustments. */

Didn't test that. Pretty sure it will work fine for you tho. I've applied block rules to pseudo-classes before. You might be stuck with a fixed width for every first word, so text-align:center; and give it a nice background or something to deal with the negative space.

Hope that works for you. :)

# direct evaluation of the return value

echo direct evaluations of the return value:

echo $dv
if (pass); then
  echo pass has no errors
else
  echo pass has errors
fi
if (fail); then
  echo fail has no errors

  echo fail has errors
fi

# this code results in error because of returned string (stdout)

JAX-WS - is Java API for the XML-Based Web Services - a standard way to develop a Web- Services in SOAP notation (Simple Object Access Protocol).

Calling of the Web Services is performed via remote procedure calls. For the exchange of information between the client and the Web Service is used SOAP protocol. Message exchange between the client and the server performed through XML- based SOAP messages.

Clients of the JAX-WS Web- Service need a WSDL file to generate executable code that the clients can use to call Web- Service.

JAX-RS - Java API for RESTful Web Services. RESTful Web Services are represented as resources and can be identified by Uniform Resource Identifiers (URI). Remote procedure call in this case is represented a HTTP- request and the necessary data is passed as parameters of the query. Web Services RESTful - more flexible, can use several different MIME- types. Typically used for XML data exchange or JSON (JavaScript Object Notation) data exchange...

Sometimes you can simply typecast:

// this is the value of my $xml
object(SimpleXMLElement)#10227 (1) {
  [0]=>
  string(2) "en"
}

$s = (string) $xml; // returns "en";

If you are using datetimepicker make sure you include the right CSS and JS files. datetimepicker uses(Take note of their names);

and

On the above question asked by @mindfreak,The main problem is due to the imported files.

You can define a global alias so you can invoke a short log in a more comfortable way:

git config --global alias.slog "log --pretty=oneline --abbrev-commit"

Then you can call it using git slog (it even works with autocompletion if you have it enabled).

Python doesn't have builtin unsigned types. You can use mathematical operations to compute a new int representing the value you would get in C, but there is no "unsigned value" of a Python int. The Python int is an abstraction of an integer value, not a direct access to a fixed-byte-size integer.

As @Musa comments it, it seems that the reason is that:

Postman doesn't care about SOP, it's a dev tool not a browser

By the way here's a chrome extension in order to make it work on your browser (this one is for chrome, but you can find either for FF or Safari).

Add to your activity theme, item colorControlActivated, for example:

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

    android:theme="@style/AppTheme.NoActionBar"/>

"I actually tried to had a normal objective discusssion over pros and cons of 1., using framework over pure javascript and 2., jquery vs. others, since jQuery seems to be easiest to work with with quickest learning curve."

Using any framework because you don't want to actually learn the underlying language is absolutely wrong not only for JavaScript, but for any other programming language.

"Is there any reason (besides browser sniffing and personal "hate" against John Resig) why jQuery is wrong?"

Most of the hate agains it comes from the exaggerated fanboyism which pollutes forums with "use jQuery" as an answer for every single JavaScript question and the overuse which produces code in which simple statements such as declaring a variable are done through library calls.

Nevertheless, there are also some legit technical issues such as the shared guilt in producing illegible code and overhead. Of course those two are aggravated by the lack of developer proficiency rather than the library itself.

As others have noted, not all decimal values can be represented as binary since decimal is based on powers of 10 and binary is based on powers of two.

If precision matters, use BigDecimal, but if you just want friendly output:

System.out.printf("%.2f\n", total);

Will give you:

What would be handy would be to apply the Camera position to a new plot. So I plot, then move the plot around with the mouse changing the distance. Then try to replicate the view including the distance on another plot. I find that axx.ax.get_axes() gets me an object with the old .azim and .elev.

IN PYTHON...

axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev
dst=axx.dist       # ALWAYS GIVES 10
#dst=ax1.axes.dist # ALWAYS GIVES 10
#dst=ax1.dist      # ALWAYS GIVES 10

Later 3d graph...

ax2.view_init(elev=ele, azim=azm) #Works!
ax2.dist=dst                       # works but always 10 from axx

EDIT 1... OK, Camera position is the wrong way of thinking concerning the .dist value. It rides on top of everything as a kind of hackey scalar multiplier for the whole graph.

This works for the magnification/zoom of the view:

xlm=ax1.get_xlim3d() #These are two tupples
ylm=ax1.get_ylim3d() #we use them in the next
zlm=ax1.get_zlim3d() #graph to reproduce the magnification from mousing
axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev

Later Graph...

ax2.view_init(elev=ele, azim=azm) #Reproduce view
ax2.set_xlim3d(xlm[0],xlm[1])     #Reproduce magnification
ax2.set_ylim3d(ylm[0],ylm[1])     #...
ax2.set_zlim3d(zlm[0],zlm[1])     #...

You could consider using CSS clip: rect(top, right, bottom, left); to clip a fixed positioned element to a parent. See demo at http://jsfiddle.net/lmeurs/jf3t0fmf/.

Beware, use with care!

Though the clip style is widely supported, main disadvantages are that:

1. The parent's position cannot be static or relative (one can use an absolutely positioned parent inside a relatively positioned container);
2. The rect coordinates do not support percentages, though the auto value equals 100%, ie. clip: rect(auto, auto, auto, auto);;
3. Possibillities with child elements are limited in at least IE11 & Chrome34, ie. we cannot set the position of child elements to relative or absolute or use CSS3 transform like scale.

See http://tympanus.net/codrops/2013/01/16/understanding-the-css-clip-property/ for more info.

EDIT: Chrome seems to handle positioning of and CSS3 transforms on child elements a lot better when applying backface-visibility, so just to be sure we added:

-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
backface-visibility: hidden;

to the main child element.

Also note that it's not fully supported by older / mobile browsers or it might take some extra effort. See our implementation for the menu at bellafuchsia.com.

1. IE8 shows the menu well, but menu links are not clickable;
2. IE9 does not show the menu under the fold;
3. iOS Safari <5 does not show the menu well;
4. iOS Safari 5+ repaints the clipped content on scroll after scrolling;
5. FF (at least 13+), IE10+, Chrome and Chrome for Android seem to play nice.

EDIT 2014-11-02: Demo URL has been updated.

First, try omitting the quotes from 12 and 24. Worth a shot.

Second, it's better to do this in CSS. See also http://www.w3schools.com/css/css_font.asp . Here is an inline style for a table tag:

<table style='font-family:"Courier New", Courier, monospace; font-size:80%' ...>...</table>

Better still, use an external style sheet or a style tag near the top of your HTML document. See also http://www.w3schools.com/css/css_howto.asp .

    return True;

Similar problem for me but a little different. I can compile and run the default CUDA 10 code with no problem, but there are a lots of error related to the stdio.h file show in the edit window. Which is annoying. I solve it by change the code file name from "kernel.cu" to "kernel.cpp". That is wired but works for me. And it runs well so far.

Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.

Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.

The answer to my question is at Ansible: best practice for maintaining list of sudoers.

The Ansible playbook code fragment looks like this from my problem:

- name: Make sure we have a 'wheel' group
  group:
    name: wheel
    state: present

- name: Allow 'wheel' group to have passwordless sudo
  lineinfile:
    dest: /etc/sudoers
    state: present
    regexp: '^%wheel'
    line: '%wheel ALL=(ALL) NOPASSWD: ALL'
    validate: 'visudo -cf %s'

- name: Add sudoers users to wheel group
  user:
    name=deployer
    groups=wheel
    append=yes
    state=present
    createhome=yes

- name: Set up authorized keys for the deployer user
  authorized_key: user=deployer key="{{item}}"
  with_file:
    - /home/railsdev/.ssh/id_rsa.pub

And the best part is that the solution is idempotent. It doesn't add the line

%wheel ALL=(ALL) NOPASSWD: ALL

to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.

To directly login to a remote mysql console, use the below command:

mysql -u {username} -p'{password}' \
    -h {remote server ip or name} -P {port} \
    -D {DB name}

For example

mysql -u root -p'root' \
        -h 127.0.0.1 -P 3306 \
        -D local

no space after -p as specified in the documentation

It will take you to the mysql console directly by switching to the mentioned database.

Use its value directly:

In [79]: df[df.c > 0.5][['b', 'e']].values
Out[79]: 
array([[ 0.98836259,  0.82403141],
       [ 0.337358  ,  0.02054435],
       [ 0.29271728,  0.37813099],
       [ 0.70033513,  0.69919695]])

Matthew Brindley, your code worked very good for some website I needed (with login), but I needed to change to HttpWebRequest and HttpWebResponse otherwise I get a 404 Bad Request from the remote server. Also I would like to share my workaround using your code, and is that I tried it to login to a website based on moodle, but it didn't work at your step "GETting the page behind the login form" because when successfully POSTing the login, the Header 'Set-Cookie' didn't return anything despite other websites does.

So I think this where we need to store cookies for next Requests, so I added this.


To the "POSTing to the login form" code block :

var cookies = new CookieContainer();
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(formUrl);
req.CookieContainer = cookies;

And To the "GETting the page behind the login form" :

HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(getUrl);
getRequest.CookieContainer = new CookieContainer();
getRequest.CookieContainer.Add(resp.Cookies);
getRequest.Headers.Add("Cookie", cookieHeader);

Doing this, lets me Log me in and get the source code of the "page behind login" (website based moodle) I know this is a vague use of the CookieContainer and HTTPCookies because we may ask first is there a previously set of cookies saved before sending the request to the server. This works without problem anyway, but here's a good info to read about WebRequest and WebResponse with sample projects and tutorial:
Retrieving HTTP content in .NET
How to use HttpWebRequest and HttpWebResponse in .NET

I had solved it on iPad. Try, if it works also on OSX.

body, html { position: fixed; }

Works only if you have content smaller then screen or you are using some layout framework (Angular Material in my case).

In Angular Material it is great, that you will disable over-scroll effect of whole page, but inner sections <md-content> can be still scrollable.

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

Create an output file and custom function:

outputFile = open('outputfile.log', 'w')

def printing(text):
    print(text)
    if outputFile:
        outputFile.write(str(text))

Then instead of print(text) in your code, call printing function.

printing("START")
printing(datetime.datetime.now())
printing("COMPLETE")
printing(datetime.datetime.now())

You can install directly from the repository (note the type="source"):

install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")

Wow, there are a lot of great answers to this question.

I didn't see one that takes a reduce approach so I'll add it in:

var searchForValue = 'pig';

var valueIsInArray = ['horse', 'cat', 'dog'].reduce(function(previous, current){
    return previous || searchForValue === current ? true : false;
}, false);

console.log('The value "' + searchForValue + '" is in the array: ' + valueIsInArray);

Here's a fiddle of it in action.

Suppose we have a collection like below:

{ 
  "_id":"1234"
  "open":"Yes"
  "things":{
             "paper":1234
             "bottle":"Available"
             "bottle_count":40
            } 
}

We want to know if the bottle field is present or not?

Ans:

db.products.find({"things.bottle":{"$exists":true}})

Consider Moshi's JsonWriter class. It has a wonderful API and it reduces copying to a minimum, everything can be nicely streamed to a filed, OutputStream, etc.

OutputStream os = ...;
JsonWriter json = new JsonWriter(Okio.buffer(Okio.sink(os)));
json.beginObject();
json.name("id").value(getId());
json.name("scores");
json.beginArray();
for (Double score : getScores()) {
  json.value(score);
}
json.endArray();
json.endObject();

If you want the string in hand:

Buffer b = new Buffer(); // okio.Buffer
JsonWriter writer = new JsonWriter(b);
//...
String jsonString = b.readUtf8();

To get all the messages stored for the topic you can seek the consumer to the beginning and end of the stream for each partition and sum the results

List<TopicPartition> partitions = consumer.partitionsFor(topic).stream()
        .map(p -> new TopicPartition(topic, p.partition()))
        .collect(Collectors.toList());
    consumer.assign(partitions); 
    consumer.seekToEnd(Collections.emptySet());
Map<TopicPartition, Long> endPartitions = partitions.stream()
        .collect(Collectors.toMap(Function.identity(), consumer::position));
    consumer.seekToBeginning(Collections.emptySet());
System.out.println(partitions.stream().mapToLong(p -> endPartitions.get(p) - consumer.position(p)).sum());

Try this:

I used for Update and Delete buttons. It doesn't touch Edit button. You can use auto generated buttons.

  protected void gvOperators_OnRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType != DataControlRowType.DataRow) return;
        var updateButton = (LinkButton)e.Row.Cells[0].Controls[0];
        if (updateButton.Text == "Update")
        {
            updateButton.OnClientClick = "return confirm('Do you really want to update?');";
        }
        var deleteButton = (LinkButton)e.Row.Cells[0].Controls[2];
        if (deleteButton.Text == "Delete")
        {
            deleteButton.OnClientClick = "return confirm('Do you really want to delete?');";
        }

    }

Personally,I prefer to use preg_match() function:

if(preg_match("/\.(gif|png|jpg)$/", $filename))

or in_array()

$exts = array('gif', 'png', 'jpg'); 
if(in_array(end(explode('.', $filename)), $exts)

With in_array() can be useful if you have a lot of extensions to validate and perfomance question. Another way to validade file images: you can use @imagecreatefrom*(), if the function fails, this mean the image is not valid.

For example:

function testimage($path)
{
   if(!preg_match("/\.(png|jpg|gif)$/",$path,$ext)) return 0;
   $ret = null;
   switch($ext)
   {
       case 'png': $ret = @imagecreatefrompng($path); break;
       case 'jpeg': $ret = @imagecreatefromjpeg($path); break;
       // ...
       default: $ret = 0;
   }

   return $ret;
}

then:

$valid = testimage('foo.png');

Assuming that foo.png is a PHP-script file with .png extension, the above function fails. It can avoid attacks like shell update and LFI.

Try this:

val rccJoin=dfRccDeuda.as("dfdeuda")
.join(dfRccCliente.as("dfcliente")
,col("dfdeuda.etarcid")===col("dfcliente.etarcid") 
&& col("dfdeuda.etarcid")===col("dfcliente.etarcid"),"inner")

This is the modern way to change URL parameters:

function setGetParam(key,value) {
  if (history.pushState) {
    var params = new URLSearchParams(window.location.search);
    params.set(key, value);
    var newUrl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?' + params.toString();
    window.history.pushState({path:newUrl},'',newUrl);
  }
}

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End

Here's a shell script I made for myself:

#! /bin/sh

for device in `adb devices | awk '{print $1}'`; do
  if [ ! "$device" = "" ] && [ ! "$device" = "List" ]
  then
    echo " "
    echo "adb -s $device $@"
    echo "------------------------------------------------------"
    adb -s $device $@
  fi
done

I dont have a direct answer, but you might want to look into these things:

• Recoil project - https://github.com/recoilphp/recoil
• php's LibEvent extension? http://www.php.net/manual/en/book.libevent.php
• process forking http://www.php.net/manual/en/function.pcntl-fork.php
• message brokers, i.e. you could start workers to make the HTTP calls and once that job is done, insert a new job describing the work that needs to be done in order to process the cached HTTP response body.

Delimiters other than the default ; are typically used when defining functions, stored procedures, and triggers wherein you must define multiple statements. You define a different delimiter like $$ which is used to define the end of the entire procedure, but inside it, individual statements are each terminated by ;. That way, when the code is run in the mysql client, the client can tell where the entire procedure ends and execute it as a unit rather than executing the individual statements inside.

Note that the DELIMITER keyword is a function of the command line mysql client (and some other clients) only and not a regular MySQL language feature. It won't work if you tried to pass it through a programming language API to MySQL. Some other clients like PHPMyAdmin have other methods to specify a non-default delimiter.

Example:

DELIMITER $$
/* This is a complete statement, not part of the procedure, so use the custom delimiter $$ */
DROP PROCEDURE my_procedure$$

/* Now start the procedure code */
CREATE PROCEDURE my_procedure ()
BEGIN    
  /* Inside the procedure, individual statements terminate with ; */
  CREATE TABLE tablea (
     col1 INT,
     col2 INT
  );

  INSERT INTO tablea
    SELECT * FROM table1;

  CREATE TABLE tableb (
     col1 INT,
     col2 INT
  );
  INSERT INTO tableb
    SELECT * FROM table2;
  
/* whole procedure ends with the custom delimiter */
END$$

/* Finally, reset the delimiter to the default ; */
DELIMITER ;

Attempting to use DELIMITER with a client that doesn't support it will cause it to be sent to the server, which will report a syntax error. For example, using PHP and MySQLi:

$mysqli = new mysqli('localhost', 'user', 'pass', 'test');
$result = $mysqli->query('DELIMITER $$');
echo $mysqli->error;

Errors with:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER $$' at line 1

A better fix than setting PYTHONPATH is to use python -m module.path

This will correctly set sys.path[0] and is a more reliable way to execute modules.

I have a quick writeup about this problem, as other answerers have mentioned the reason for this is python path/to/file.py puts path/to on the beginning of the PYTHONPATH (sys.path).

Had similar problems recently. Would suggest you carefully check if the user you're connecting with has proper authorizations on the remote machine.

You can review permissions using the following command.

Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell

Found this tip here (updated link, thanks "unbob"):

https://devblogs.microsoft.com/scripting/configure-remote-security-settings-for-windows-powershell/

It fixed it for me.

You can save this in your shell.rc or just put in console

function absolute_path { echo "$PWD/$1"; }
alias ap="absolute_path"

example:

ap somefile.txt

will output

/home/user/somefile.txt

If you can possibly help it, DO NOT USE .scrollHeight.

.scrollHeight does not yield the same kind of results in different browsers in certain circumstances (most prominently while scrolling).

For example:

<div id='outer' style='width:100px; height:350px; overflow-y:hidden;'>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
<div style='width:100px; height:150px;'></div>
</div>

If you do

console.log($('#outer').scrollHeight);

you'll get 900px in Chrome, FireFox and Opera. That's great.

But, if you attach a wheelevent / wheel event to #outer, when you scroll it, Chrome will give you a constant value of 900px (correct) but FireFox and Opera will change their values as you scroll down (incorrect).

A very simple way to do this is like so (a bit of a cheat, really). (This example works while dynamically adding content to #outer as well):

$('#outer').css("height", "auto");
var outerContentsHeight = $('#outer').height();
$('#outer').css("height", "350px");

console.log(outerContentsHeight); //Should get 900px in these 3 browsers

The reason I pick these three browsers is because all three can disagree on the value of .scrollHeight in certain circumstances. I ran into this issue making my own scrollpanes. Hope this helps someone.

Use

//$arr should be array as you mentioned as below
foreach($arr as $key=>$value){
  echo $value->sm_id;
}

OR

//$arr should be array as you mentioned as below
foreach($arr as $value){
  echo $value->sm_id;
}

I was also having same issue and stuck for some days, but after some research i figured out that we can actually use chrome's "--remote-debugging-port" to intercept requests in conjunction with selenium web driver. Use following Pseudocode as a reference:-

create instance of chrome driver with remote debugging

int freePort = findFreePort();

chromeOptions.addArguments("--remote-debugging-port=" + freePort);

ChromeDriver driver = new ChromeDriver(chromeOptions);`

make a get call to http://127.0.0.1:freePort

String response = makeGetCall( "http://127.0.0.1" + freePort  + "/json" );

Extract chrome's webSocket Url to listen, you can see response and figure out how to extract

String webSocketUrl = response.substring(response.indexOf("ws://127.0.0.1"), response.length() - 4);

Connect to this socket, u can use asyncHttp

socket = maketSocketConnection( webSocketUrl );

Enable network capture

socket.send( { "id" : 1, "method" : "Network.enable" } );

Now chrome will send all network related events and captures them as follows

socket.onMessageReceived( String message ){

    Json responseJson = toJson(message);
    if( responseJson.method == "Network.responseReceived" ){
       //extract status code
    }
}

driver.get("http://stackoverflow.com");

you can do everything mentioned in dev tools site. see https://chromedevtools.github.io/devtools-protocol/ Note:- use chromedriver 2.39 or above.

I hope it helps someone.

A simple tip: A simple space (or invisible special char) in your script, right before the very first <?php tag, can cause this ! Especially when you are working in a team and somebody is using a "weak" IDE or has messed around in the files with strange text editors.

I have seen these things ;)

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.
