Run the cmd as run as administrator this worked for me

When I am developing, I prefer to use this practical class to configure Migrations.

Hope it helps.

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
        this.Configuration.LazyLoadingEnabled = false;
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();

        Database.SetInitializer(new StackOverflowInitializer());
    }

    public class StackOverflowInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext>
    {
        public StackOverflowInitializer()
        {
            // TODO NOTHING, COMMENT ALL

            // IF CHANGES, RECREATE
            Database.SetInitializer(new DropCreateDatabaseIfModelChanges<ApplicationDbContext>());

            // CREATE ONLY NOT EXITS
            //Database.SetInitializer<Context>(new CreateDatabaseIfNotExists<ApplicationDbContext>());
        }

    }

    public System.Data.Entity.DbSet<stackoverflow.Models.Company> Companies { get; set; }

}

Those who still have the problem with onAttach(Activity activity), Its just changed to Context -

    @Override
public void onAttach(Context context) {
    super.onAttach(context);
    this.context = context;
}

In most cases saving the context will be enough for you - for example if you want to do getResources() you can do it straight from the context. If you still need to make the context into your Activity do so -

 @Override
public void onAttach(Context context) {
    super.onAttach(context);
    mActivity a; //Your activity class - will probably be a global var.
    if (context instanceof mActivity){
        a=(mActivity) context;
    }
}

What exactly are the rules for requesting retransmission of lost data?

The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.

Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ

are detailed in the RFC 3366.

At what time frequency are the retransmission requests performed?

The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)

The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.

Is there an upper bound on the number?

Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.

Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?

The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

You could use Universal Encoding Detector, but be aware that it will just give you best guess, not the actual encoding, because it's impossible to know encoding of a string "abc" for example. You will need to get encoding information elsewhere, eg HTTP protocol uses Content-Type header for that.

Your query would work already - except that you are running into naming conflicts or just confusing the output column (the CASE expression) with source column result, which has different content.

...
GROUP BY model.name, attempt.type, attempt.result
...

You need to GROUP BY your CASE expression instead of your source column:

...
GROUP BY model.name, attempt.type
       , CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END
...

Or provide a column alias that's different from any column name in the FROM list - or else that column takes precedence:

SELECT ...
     , CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END AS result1
...
GROUP BY model.name, attempt.type, result1
...

The SQL standard is rather peculiar in this respect. Quoting the manual here:

An output column's name can be used to refer to the column's value in ORDER BY and GROUP BY clauses, but not in the WHERE or HAVING clauses; there you must write out the expression instead.

And:

If an ORDER BY expression is a simple name that matches both an output column name and an input column name, ORDER BY will interpret it as the output column name. This is the opposite of the choice that GROUP BY will make in the same situation. This inconsistency is made to be compatible with the SQL standard.

Bold emphasis mine.

These conflicts can be avoided by using positional references (ordinal numbers) in GROUP BY and ORDER BY, referencing items in the SELECT list from left to right. See solution below.
The drawback is, that this may be harder to read and vulnerable to edits in the SELECT list (one might forget to adapt positional references accordingly).

But you do not have to add the column day to the GROUP BY clause, as long as it holds a constant value (CURRENT_DATE-1).

Rewritten and simplified with proper JOIN syntax and positional references it could look like this:

SELECT m.name
     , a.type
     , CASE WHEN a.result = 0 THEN 0 ELSE 1 END AS result
     , CURRENT_DATE - 1 AS day
     , count(*) AS ct
FROM   attempt    a
JOIN   prod_hw_id p USING (hard_id)
JOIN   model      m USING (model_id)
WHERE  ts >= '2013-11-06 00:00:00'  
AND    ts <  '2013-11-07 00:00:00'
GROUP  BY 1,2,3
ORDER  BY 1,2,3;

Also note that I am avoiding the column name time. That's a reserved word and should never be used as identifier. Besides, your "time" obviously is a timestamp or date, so that is rather misleading.

You need to create another migration file - and place it in there:

Run

Laravel 4:    php artisan migrate:make rename_stnk_column
Laravel 5:    php artisan make:migration rename_stnk_column

Then inside the new migration file place:

class RenameStnkColumn extends Migration
{

    public function up()
    {
        Schema::table('stnk', function(Blueprint $table) {
            $table->renameColumn('id', 'id_stnk');
        });
    }


    public function down()
    {
        Schema::table('stnk', function(Blueprint $table) {
            $table->renameColumn('id_stnk', 'id');
        });
    }

}

((portion/total) * 100).toFixed(2) + '%'

I'm having a problem with your script in Firefox. When I scroll down, the script continues to add a margin to the page and I never reach the bottom of the page. This occurs because the ActionBox is still part of the page elements. I posted a demo here.

• One solution would be to add a position: fixed to the CSS definition, but I see this won't work for you
• Another solution would be to position the ActionBox absolutely (to the document body) and adjust the top.
• Updated the code to fit with the solution found for others to benefit.

UPDATED:

CSS

#ActionBox {
 position: relative;
 float: right;
}

Script

var alert_top = 0;
var alert_margin_top = 0;

$(function() {
  alert_top = $("#ActionBox").offset().top;
  alert_margin_top = parseInt($("#ActionBox").css("margin-top"),10);

  $(window).scroll(function () {
    var scroll_top = $(window).scrollTop();
    if (scroll_top > alert_top) {
      $("#ActionBox").css("margin-top", ((scroll_top-alert_top)+(alert_margin_top*2)) + "px");
      console.log("Setting margin-top to " + $("#ActionBox").css("margin-top"));
    } else {
      $("#ActionBox").css("margin-top", alert_margin_top+"px");
    };
  });
});

Also it is important to add a base (10 in this case) to your parseInt(), e.g.

parseInt($("#ActionBox").css("top"),10);

Unfortunately there is no perfect way, unless you use _proto_ recursively and access all non-enumerable properties, but this works in Firefox only.

So the best I can do is to guess usage scenarios.

1) Fast and limited.

Works when you have simple JSON-style objects without methods and DOM nodes inside:

 JSON.stringify(obj1) === JSON.stringify(obj2) 

The ORDER of the properties IS IMPORTANT, so this method will return false for following objects:

 x = {a: 1, b: 2};
 y = {b: 2, a: 1};

2) Slow and more generic.

Compares objects without digging into prototypes, then compares properties' projections recursively, and also compares constructors.

This is almost correct algorithm:

function deepCompare () {
  var i, l, leftChain, rightChain;

  function compare2Objects (x, y) {
    var p;

    // remember that NaN === NaN returns false
    // and isNaN(undefined) returns true
    if (isNaN(x) && isNaN(y) && typeof x === 'number' && typeof y === 'number') {
         return true;
    }

    // Compare primitives and functions.     
    // Check if both arguments link to the same object.
    // Especially useful on the step where we compare prototypes
    if (x === y) {
        return true;
    }

    // Works in case when functions are created in constructor.
    // Comparing dates is a common scenario. Another built-ins?
    // We can even handle functions passed across iframes
    if ((typeof x === 'function' && typeof y === 'function') ||
       (x instanceof Date && y instanceof Date) ||
       (x instanceof RegExp && y instanceof RegExp) ||
       (x instanceof String && y instanceof String) ||
       (x instanceof Number && y instanceof Number)) {
        return x.toString() === y.toString();
    }

    // At last checking prototypes as good as we can
    if (!(x instanceof Object && y instanceof Object)) {
        return false;
    }

    if (x.isPrototypeOf(y) || y.isPrototypeOf(x)) {
        return false;
    }

    if (x.constructor !== y.constructor) {
        return false;
    }

    if (x.prototype !== y.prototype) {
        return false;
    }

    // Check for infinitive linking loops
    if (leftChain.indexOf(x) > -1 || rightChain.indexOf(y) > -1) {
         return false;
    }

    // Quick checking of one object being a subset of another.
    // todo: cache the structure of arguments[0] for performance
    for (p in y) {
        if (y.hasOwnProperty(p) !== x.hasOwnProperty(p)) {
            return false;
        }
        else if (typeof y[p] !== typeof x[p]) {
            return false;
        }
    }

    for (p in x) {
        if (y.hasOwnProperty(p) !== x.hasOwnProperty(p)) {
            return false;
        }
        else if (typeof y[p] !== typeof x[p]) {
            return false;
        }

        switch (typeof (x[p])) {
            case 'object':
            case 'function':

                leftChain.push(x);
                rightChain.push(y);

                if (!compare2Objects (x[p], y[p])) {
                    return false;
                }

                leftChain.pop();
                rightChain.pop();
                break;

            default:
                if (x[p] !== y[p]) {
                    return false;
                }
                break;
        }
    }

    return true;
  }

  if (arguments.length < 1) {
    return true; //Die silently? Don't know how to handle such case, please help...
    // throw "Need two or more arguments to compare";
  }

  for (i = 1, l = arguments.length; i < l; i++) {

      leftChain = []; //Todo: this can be cached
      rightChain = [];

      if (!compare2Objects(arguments[0], arguments[i])) {
          return false;
      }
  }

  return true;
}

Known issues (well, they have very low priority, probably you'll never notice them):

• objects with different prototype structure but same projection
• functions may have identical text but refer to different closures

Tests: passes tests are from How to determine equality for two JavaScript objects?.

If your IEnumerable doesn't expose it's <T> and Linq fails, you can write a method using reflection:

public static T GetEnumeratedItem<T>(Object items, int index) where T : class
{
  T item = null;
  if (items != null)
  {
    System.Reflection.MethodInfo mi = items.GetType()
      .GetMethod("GetEnumerator");
    if (mi != null)
    {
      object o = mi.Invoke(items, null);
      if (o != null)
      {
        System.Reflection.MethodInfo mn = o.GetType()
          .GetMethod("MoveNext");
        if (mn != null)
        {
          object next = mn.Invoke(o, null);
          while (next != null && next.ToString() == "True")
          {
            if (index < 1)
            {
              System.Reflection.PropertyInfo pi = o
                .GetType().GetProperty("Current");
              if (pi != null) item = pi
                .GetValue(o, null) as T;
              break;
            }
            index--;
          }
        }
      }
    }
  }
  return item;
}

Short and simple:

new DirectoryInfo(path).GetFiles().OrderByDescending(o => o.LastWriteTime).FirstOrDefault();

This is completely possible with just CSS-- no JavaScript needed: Here's an example

If you launch the VM with the the launchpad (genymotion binary where you download the VMs) and you set the Android SDK path into the application parameters the connection is automatic and you don't need to run adb connect

You can find the information in the Genymotion Docs.

It depends what kind of UUID you want.

• The standard Java UUID class generates Version 4 (random) UUIDs. (UPDATE - Version 3 (name) UUIDs can also be generated.) It can also handle other variants, though it cannot generate them. (In this case, "handle" means construct UUID instances from long, byte[] or String representations, and provide some appropriate accessors.)

• The Java UUID Generator (JUG) implementation purports to support "all 3 'official' types of UUID as defined by RFC-4122" ... though the RFC actually defines 4 types and mentions a 5th type.

For more information on UUID types and variants, there is a good summary in Wikipedia, and the gory details are in RFC 4122 and the other specifications.

When making many plots, it makes sense to set it globally (relevant part is the second line, three lines together are a working example):

   library('ggplot2')
   theme_update(text = element_text(size=20))
   ggplot(mpg, aes(displ, hwy, colour = class)) + geom_point()

The .NET framework has some built-in classes which allows you to send e-mail via your app.

You should take a look in the System.Net.Mail namespace, where you'll find the MailMessage and SmtpClient classes. You can set the BodyFormat of the MailMessage class to MailFormat.Html.

It could also be helpfull if you make use of the AlternateViews property of the MailMessage class, so that you can provide a plain-text version of your mail, so that it can be read by clients that do not support HTML.

Maybe try this?

SELECT * INTO tmpFerdeen (

Here's a brief tutorial on how __doPostBack() works.

To be honest, I don't use it much; at least directly. Many server controls, (e.g., Button, LinkButton, ImageButton, parts of the GridView, etc.) use __doPostBack as their post back mechanism.

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

answer to your question is simple order is not a object make it an array. var order = new Array(); order.push(/item to push/); when ever this error appears just check the left of which property the error is in this case it is push which is order[] so it is undefined.

I am aware that there's already an accepted answer but would like to add my two cents nevertheless:

TLDR: Future and Promise are the two sides of an asynchronous operation: consumer/caller vs. producer/implementor.

As a caller of an asynchronous API method, you will get a Future as a handle to the computation's result. You can e.g. call get() on it to wait for the computation to complete and retrieve the result.

Now think of how this API method is actually implemented: The implementor must return a Future immediately. They are responsible for completing that future as soon as the computation is done (which they will know because it is implementing the dispatch logic ;-)). They will use a Promise/CompletableFuture to do just that: Construct and return the CompletableFuture immediately, and call complete(T result) once the computation is done.

Python 2, using lambda

>>> head, tail = (lambda lst: (lst[0], lst[1:]))([1, 1, 2, 3, 5, 8, 13, 21, 34, 55])
>>> head
1
>>> tail
[1, 2, 3, 5, 8, 13, 21, 34, 55]

TL;DR Make a copy or alias of your python.exe with name python2.7.exe

My python 2.7 was installed as

D:\app\Python27\python.exe

I always got this error no matter how I set (and verified) PYTHON env variable:

gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable.
gyp ERR! stack     at failNoPython (C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\lib\configure.js:103:14)

The reason for this was that in node-gyp's configure.js the python executable was resolved like:

var python = gyp.opts.python || process.env.PYTHON || 'python'

And it turned out that gyp.opts.python had value 'python2.7' thus overriding process.env.PYTHON.

I resolved this by creating an alias for python.exe executable with name node-gyp was looking for:

D:\app\Python27>mklink python2.7.exe python.exe

You need admin rights for this operation.

For me it was changing.

this.name = response.data;

To what computed returns so;

this.$store.state.name = response.data;

function getBackgroundPositionX(sel) {
    pos = $(sel).css('backgroundPosition').split(' ');
    return parseFloat(pos[0].substring(0, pos[0].length-2));
}

This returns [x] value. Length of number has no matter. Could be e.g. 9999 or 0.

The problem is WHEN the event is added and EXECUTED via triggering (the document onload property modification can be verified by examining the properties list).

When does this execute and modify onload relative to the onload event trigger:

document.addEventListener('load', ... );

before, during or after the load and/or render of the page's HTML?
This simple scURIple (cut & paste to URL) "works" w/o alerting as naively expected:

data:text/html;charset=utf-8,
    <html content editable><head>
          <script>
                document.addEventListener('load', function(){ alert(42) } );
          </script>
          </head><body>goodbye universe - hello muiltiverse</body>
    </html>

Does loading imply script contents have been executed?

A little out of this world expansion ...
Consider a slight modification:

data:text/html;charset=utf-8,
    <html content editable><head>
          <script>
              if(confirm("expand mind?"))document.addEventListener('load', function(){ alert(42) } );
          </script>
        </head><body>goodbye universe - hello muiltiverse</body>
    </html>

and whether the HTML has been loaded or not.

Rendering is certainly pending since goodbye universe - hello muiltiverse is not seen on screen but, does not the confirm( ... ) have to be already loaded to be executed? ... and so document.addEventListener('load', ... ) ... ?

In other words, can you execute code to check for self-loading when the code itself is not yet loaded?

Or, another way of looking at the situation, if the code is executable and executed then it has ALREADY been loaded as a done deal and to retroactively check when the transition occurred between not yet loaded and loaded is a priori fait accompli.

So which comes first: loading and executing the code or using the code's functionality though not loaded?

onload as a window property works because it is subordinate to the object and not self-referential as in the document case, ie. it's the window's contents, via document, that determine the loaded question err situation.

PS.: When do the following fail to alert(...)? (personally experienced gotcha's):

caveat: unless loading to the same window is really fast ... clobbering is the order of the day
so what is really needed below when using the same named window:

window.open(URIstr1,"w") .
   addEventListener('load', 
      function(){ alert(42); 
         window.open(URIstr2,"w") .
            addEventListener('load', 
               function(){ alert(43); 
                  window.open(URIstr3,"w") .
                     addEventListener('load', 
                        function(){ alert(44); 
                 /*  ...  */
                        } )
               } )
      } ) 

alternatively, proceed each successive window.open with:
alert("press Ok either after # alert shows pending load is done or inspired via divine intervention" );

data:text/html;charset=utf-8,
    <html content editable><head><!-- tagging fluff --><script>

        window.open(
            "data:text/plain, has no DOM or" ,"Window"
         ) . addEventListener('load', function(){ alert(42) } )

        window.open(
            "data:text/plain, has no DOM but" ,"Window"
         ) . addEventListener('load', function(){ alert(4) } )

        window.open(
            "data:text/html,<html><body>has DOM and", "Window"
         ) . addEventListener('load', function(){ alert(2) } )

        window.open(
            "data:text/html,<html><body>has DOM and", "noWindow"
         ) . addEventListener('load', function(){ alert(1) } )

        /* etc. including where body has onload=... in each appropriate open */

    </script><!-- terminating fluff --></head></html>

which emphasize onload differences as a document or window property.

Another caveat concerns preserving XSS, Cross Site Scripting, and SOP, Same Origin Policy rules which may allow loading an HTML URI but not modifying it's content to check for same. If a scURIple is run as a bookmarklet/scriplet from the same origin/site then there maybe success.

ie. From an arbitrary page, this link will do the load but not likely do alert('done'):

    <a href="javascript:window.open('view-source:http://google.ca') . 
                   addEventListener( 'load',  function(){ alert('done') }  )"> src. vu </a>

but if the link is bookmarked and then clicked when viewing a google.ca page, it does both.

You can find it at the localhost main page at Your Aliases section.

The below code works fine but I am not sure about the radio button and dropdown list

$( '#form_id' ).submit( function( event ) {
    event.preventDefault();

    //validate fields
    var fail = false;
    var fail_log = '';
    var name;
    $( '#form_id' ).find( 'select, textarea, input' ).each(function(){
        if( ! $( this ).prop( 'required' )){

        } else {
            if ( ! $( this ).val() ) {
                fail = true;
                name = $( this ).attr( 'name' );
                fail_log += name + " is required \n";
            }

        }
    });

    //submit if fail never got set to true
    if ( ! fail ) {
        //process form here.
    } else {
        alert( fail_log );
    }

});

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

Check out this MD5 implementation for JavaScript. Its BSD Licensed and really easy to use. Example:

md5 = hex_md5("message to digest")

I had the same problem because i had an old version of Virtual Box (4.0.0).
So, I uninstalled genymotion and the old version of VB,
and I installed genymotion with virtual box (5.0.28).
And Its worked fine.

Html.DisplayFor() will render the DisplayTemplate that matches the property's type.

If it can't find any, I suppose it invokes .ToString().

If you don't know about display templates, they're partial views that can be put in a DisplayTemplates folder inside the view folder associated to a controller.

Example:

If you create a view named String.cshtml inside the DisplayTemplates folder of your views folder (e.g Home, or Shared) with the following code:

@model string

@if (string.IsNullOrEmpty(Model)) {
   <strong>Null string</strong>
}
else {
   @Model
}

Then @Html.DisplayFor(model => model.Title) (assuming that Title is a string) will use the template and display <strong>Null string</strong> if the string is null, or empty.

This is not something that SVG 1.1 supports. SVG 1.2 does have the textArea element, with automatic word wrapping, but it's not implemented in all browsers. SVG 2 does not plan on implementing textArea, but it does have auto-wrapped text.

However, given that you already know where your linebreaks should occur, you can break your text into multiple <tspan>s, each with x="0" and dy="1.4em" to simulate actual lines of text. For example:

<g transform="translate(123 456)"><!-- replace with your target upper left corner coordinates -->
  <text x="0" y="0">
    <tspan x="0" dy="1.2em">very long text</tspan>
    <tspan x="0" dy="1.2em">I would like to linebreak</tspan>
  </text>
</g>

Of course, since you want to do that from JavaScript, you'll have to manually create and insert each element into the DOM.

Finally found a solution for this by adding this line to gradle.properties.

org.gradle.jvmargs=-Xmx4608m

Here is yet another one-liner for you:

your_array.sort((a, b) => a.distance === b.distance ? 0 : a.distance > b.distance || -1);

You can draw the image on the canvas and let the user draw on top of that.

The drawImage() function will help you with that, see https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Canvas_tutorial/Using_images

If you get the server response as a String, without using a third party library you can do

JSONObject json = new JSONObject(response);
JSONObject jsonResponse = json.getJSONObject("response");
String team = jsonResponse.getString("Team");

Here is the documentation

Otherwise to parse json you can use Gson or Jackson

EDIT without libraries (not tested)

class retrievedata extends AsyncTask<Void, Void, String>{
    @Override
    protected String doInBackground(Void... params) {

        HttpURLConnection urlConnection = null;
        BufferedReader reader = null;

        URL url;
        try {
            url = new URL("http://myurlhere.com");
            urlConnection.setRequestMethod("GET"); //Your method here 
            urlConnection.connect();

            InputStream inputStream = urlConnection.getInputStream();
            StringBuffer buffer = new StringBuffer();
            if (inputStream == null) {
                return null;
            }
            reader = new BufferedReader(new InputStreamReader(inputStream));

            String line;
            while ((line = reader.readLine()) != null)
                buffer.append(line + "\n");

            if (buffer.length() == 0)
                return null;

            return buffer.toString();
        } catch (IOException e) {
            Log.e(TAG, "IO Exception", e);
            exception = e;
            return null;
        } finally {
            if (urlConnection != null) {
                urlConnection.disconnect();
            }
            if (reader != null) {
                try {
                    reader.close();
                } catch (final IOException e) {
                    exception = e;
                    Log.e(TAG, "Error closing stream", e);
                }
            }
        }
    }

    @Override
    protected void onPostExecute(String response) {
        if(response != null) {
            JSONObject json = new JSONObject(response);
            JSONObject jsonResponse = json.getJSONObject("response");
            String team = jsonResponse.getString("Team");
        }
    }
}

Add display:block; to your iframe css.

div, iframe {
    width: 100px;
    height: 50px;
    margin: 0 auto;
    background-color: #777;
}

iframe {
    display: block;
    border-style:none;
}

<div>div</div>
<iframe src="data:,iframe"></iframe>

You can create your view directly from the Layout Inflater, you only need to use the name of your layout XML file and the ID of the layout in file.

Your XML file should have an ID like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/dialog_layout_root"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:padding="10dp"
              />

And then you can set your layout on the builder with the following code:

LayoutInflater inflater = getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.dialog_layout, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

In addition to the answer of @teylyn, I would like to add that you can put the string of multiple search terms inside a SINGLE cell (as opposed to using a different cell for each term and then using that range as argument to SEARCH), using named ranges and the EVALUATE function as I found from this link.

For example, I put the following terms as text in a cell, $G$1:

"PRB", "utilization", "alignment", "spectrum"

Then, I defined a named range named search_terms for that cell as described in the link above and shown in the figure below:

In the Refers to: field I put the following:

=EVALUATE("{" & TDoc_List!$G$1 & "}")

The above EVALUATE expression is simple used to emulate the literal string

{"PRB", "utilization", "alignment", "spectrum"}

to be used as input to the SEARCH function: using a direct reference to the SINGLE cell $G$1 (augmented with the curly braces in that case) inside SEARCH does not work, hence the use of named ranges and EVALUATE.

The trick now consists in replacing the direct reference to $G$1 by the EVALUATE-augmented named range search_terms.

It really works, and shows once more how powerful Excel really is!

Hope this helps.

If you're willing to transmit some data and that you don't need to be secured (any public infos) you can use a CORS proxy, it's very easy, you'll not have to change anything in your code or in server side (especially of it's not your server like the Yahoo API or OpenWeather). I've used it to fetch JSON files with an XMLHttpRequest and it worked fine.

You can use this, it works fine:

<input type="date" class="form1"  
  value="{{date | date:MM/dd/yyyy}}"
  ng-model="date" 
  name="id" 
  validatedateformat 
  data-date-format="mm/dd/yyyy"
  maxlength="10" 
  id="id" 
  calendar 
  maxdate="todays"
  ng-click="openCalendar('id')">
    <span class="input-group-addon">
      <span class="glyphicon glyphicon-calendar" ng-click="openCalendar('id')"></span>
    </span>
</input>

Get rid of the values keyword and the parens. You can see an example here.

This is basic INSERT syntax:

INSERT INTO "table_name" ("column1", "column2", ...)
VALUES ("value1", "value2", ...);

This is the INSERT SELECT syntax:

INSERT INTO "table1" ("column1", "column2", ...)
SELECT "column3", "column4", ...
FROM "table2";

When one should inline :

1.When one want to avoid overhead of things happening when function is called like parameter passing , control transfer, control return etc.

2.The function should be small,frequently called and making inline is really advantageous since as per 80-20 rule,try to make those function inline which has major impact on program performance.

As we know that inline is just a request to compiler similar to register and it will cost you at Object code size.

// The below C++ function checks for a palindrome and 
// returns true if it is a palindrome and returns false otherwise

bool checkPalindrome ( string s )
{
    // This calculates the length of the string

    int n = s.length();

    // the for loop iterates until the first half of the string
    // and checks first element with the last element,
    // second element with second last element and so on.
    // if those two characters are not same, hence we return false because
    // this string is not a palindrome 

    for ( int i = 0; i <= n/2; i++ ) 
    {
        if ( s[i] != s[n-1-i] )
            return false;
    }
    
    // if the above for loop executes completely , 
    // this implies that the string is palindrome, 
    // hence we return true and exit

    return true;
}

use this filter:

(dns.flags.response == 0) and (ip.src == 159.25.78.7)

what this query does is it only gives dns queries originated from your ip

Instance variables are common to every object that you creating. say, there is two instance variables

class ExpThisKeyWord{
int x;
int y;

public void setMyInstanceValues(int a, int b) {
    x= a;
    y=b;

    System.out.println("x is ="+x);
    System.out.println("y is ="+y);
}

}




class Demo{
public static void main(String[] args){

ExpThisKeyWord obj1 = new ExpThisKeyWord();
ExpThisKeyWord obj2 = new ExpThisKeyWord();
ExpThisKeyWord obj3 = new ExpThisKeyWord();

obj1.setMyInstanceValues(1, 2);
obj2.setMyInstanceValues(11, 22);
obj3.setMyInstanceValues(111, 222);



}
}

if you noticed above code, we have initiated three objects and three objects are calling SetMyInstanceValues method. How do you think JVM correctly assign the values for every object? there is the trick, JVM will not see this code how it is showed above. instead of that, it will see like below code;

public void setMyInstanceValues(int a, int b) {
    this.x= a; //Answer: this keyword denotes the current object that is handled by JVM.
    this.y=b;

    System.out.println("x is ="+x);
    System.out.println("y is ="+y);
}

Array notation and pointer arithmetic can be used interchangeably in C/C++ (this is not true for ALL the cases but by the time you get there, you will find the cases yourself). So although str is a pointer, you can use it as if it were an array like so:

char char_E = str[1];
char char_L1 = str[2];
char char_O = str[4];

...and so on. What you could also do is "add" 1 to the value of the pointer to a character str which will then point to the second character in the string. Then you can simply do:

str = str + 1; // makes it point to 'E' now
char myChar =  *str;

I hope this helps.

def oneFunction(lists):
    category=random.choice(list(lists.keys()))
    word=random.choice(lists[category])
    return word

def anotherFunction():
    for letter in word:             
        print("_",end=" ")

Correct answer is simply:

SELECT a.group_id
FROM a 
LEFT JOIN b ON a.group_id=b.group_id  and b.user_id = 4
where b.user_id is null
  and a.keyword like '%keyword%'

Here we are checking user_id = 4 (your user id from the session). Since we have it in the join criteria, it will return null values for any row in table b that does not match the criteria - ie, any group that that user_id is NOT in.

From there, all we need to do is filter for the null values, and we have all the groups that your user is not in.

demo here

puts true ? "true" : "false"
=> "true"


puts false ? "true" : "false"
=> "false"

yourArray.indexOf(yourArrayKeyName) > -1

fruit = ['apple', 'grapes', 'banana']

fruit.indexOf('apple') > -1

true

fruit = ['apple', 'grapes', 'banana']

fruit.indexOf('apple1') > -1

false

You can also run conditional statements on the Postion() which can be really helpful in many scenarios.

for eg.

 <xsl:if test="(position( )) = 1">
     //Show header only once
    </xsl:if>

At this time, the only video codec that truly supports an alpha channel is VP8, which Flash uses. MP4 would probably support it if the video was exported as an image sequence, but I'm fairly certain Ogg video files have no support whatsoever for an alpha channel. This might be one of those rare instances where sticking with Flash would serve you better.

volatile is a field modifier, while synchronized modifies code blocks and methods. So we can specify three variations of a simple accessor using those two keywords:

    int i1;
    int geti1() {return i1;}

    volatile int i2;
    int geti2() {return i2;}

    int i3;
    synchronized int geti3() {return i3;}

geti1() accesses the value currently stored in i1 in the current thread. Threads can have local copies of variables, and the data does not have to be the same as the data held in other threads.In particular, another thread may have updated i1 in it's thread, but the value in the current thread could be different from that updated value. In fact Java has the idea of a "main" memory, and this is the memory that holds the current "correct" value for variables. Threads can have their own copy of data for variables, and the thread copy can be different from the "main" memory. So in fact, it is possible for the "main" memory to have a value of 1 for i1, for thread1 to have a value of 2 for i1 and for thread2 to have a value of 3 for i1 if thread1 and thread2 have both updated i1 but those updated value has not yet been propagated to "main" memory or other threads.

On the other hand, geti2() effectively accesses the value of i2 from "main" memory. A volatile variable is not allowed to have a local copy of a variable that is different from the value currently held in "main" memory. Effectively, a variable declared volatile must have it's data synchronized across all threads, so that whenever you access or update the variable in any thread, all other threads immediately see the same value. Generally volatile variables have a higher access and update overhead than "plain" variables. Generally threads are allowed to have their own copy of data is for better efficiency.

There are two differences between volitile and synchronized.

Firstly synchronized obtains and releases locks on monitors which can force only one thread at a time to execute a code block. That's the fairly well known aspect to synchronized. But synchronized also synchronizes memory. In fact synchronized synchronizes the whole of thread memory with "main" memory. So executing geti3() does the following:

1. The thread acquires the lock on the monitor for object this .
2. The thread memory flushes all its variables, i.e. it has all of its variables effectively read from "main" memory .
3. The code block is executed (in this case setting the return value to the current value of i3, which may have just been reset from "main" memory).
4. (Any changes to variables would normally now be written out to "main" memory, but for geti3() we have no changes.)
5. The thread releases the lock on the monitor for object this.

So where volatile only synchronizes the value of one variable between thread memory and "main" memory, synchronized synchronizes the value of all variables between thread memory and "main" memory, and locks and releases a monitor to boot. Clearly synchronized is likely to have more overhead than volatile.

To add a small bit to Sydius' answer, smart pointers will often provide a more stable solution by catching many easy to make errors. Raw pointers will have some perfromance advantages and can be more flexible in certain circumstances. You may also be forced to use raw pointers when linking into certain 3rd party libraries.

I checked all the solutions on this post and the post that @kenorb referenced above, and I did not find any solution that worked for me.

I am using Git 1.9.5 Preview on Windows 7 with the following configuration: - Run Git from the Windows Command Prompt - Checkout Windows-style, commit Unix-style line endings

I used the 'Git Bash' console for everything... And all was well until I tried to install the SSH keys. GitHub's documentation says to do the following (don't run these commands until you finish reading the post):

Ensure ssh-agent is enabled:

If you are using Git Bash, turn on ssh-agent:

# start the ssh-agent in the background
ssh-agent -s
# Agent pid 59566

If you are using another terminal prompt, such as msysgit, turn on ssh-agent:

# start the ssh-agent in the background
eval $(ssh-agent -s)
# Agent pid 59566

Now of course I missed the fact that you were supposed to do one or the other. So, I ran these commands multiple times because the later ssh-add command was failing, so I returned to this step, and continued to retry over and over.

This results in 1 Windows 'ssh-agent' process being created every single time you run these commands (notice the new PID every time you enter those commands?)

So, Ctrl+Alt+Del and hit End Process to stop each 'ssh-agent.exe' process.

Now that all the messed up stuff from the failed attempts is cleaned up, I will tell you how to get it working...

In 'Git Bash':

Start the 'ssh-agent.exe' process

eval $(ssh-agent -s)

And install the SSH keys

ssh-add "C:\Users\MyName\.ssh\id_rsa"

* Adjust the path above with your username, and make sure that the location of the* /.ssh directory is in the correct place. I think you choose this location during the Git installation? Maybe not...

The part I was doing wrong before I figured this out was I was not using quotes around the 'ssh-add' location. The above is how it needs to be entered on Windows.

I solved this problem :

> Preferences –> Browse Packages –> Default 

Open the exec.py file, near line 41-42, the code should look like this :

for k, v in proc_env.iteritems():
    proc_env[k] = os.path.expandvars(v).encode(sys.getfilesystemencoding())

then delete it or edit it as :

try:    
    for k, v in proc_env.iteritems():
        proc_env[k] = os.path.expandvars(v).encode(sys.getfilesystemencoding())
except:
    print 'foobar'

Wonder why nobody said it here earlier: to prevent <a href="#"> from scrolling document position to the top, simply use <a href="#/"> instead. That's mere HTML, no JQuery needed. Using event.preventDefault(); is just too much!

ApplicationId must be of type UniqueIdentifier. Your code works fine if you do:

DECLARE @TTEST TABLE
(
  TEST UNIQUEIDENTIFIER
)

DECLARE @UNIQUEX UNIQUEIDENTIFIER
SET @UNIQUEX = NEWID();

INSERT INTO @TTEST
(TEST)
VALUES
(@UNIQUEX);

SELECT * FROM @TTEST

Therefore I would say it is safe to assume that ApplicationId is not the correct data type.

This isn't appropriate in all situations but you can conditionally return false inside the component itself if a certain criteria is or isn't met.

It doesn't unmount the component, but it removes all rendered content. This would only be bad, in my mind, if you have event listeners in the component that should be removed when the component is no longer needed.

import React, { Component } from 'react';

export default class MyComponent extends Component {
    constructor(props) {
        super(props);

        this.state = {
            hideComponent: false
        }
    }

    closeThis = () => {
        this.setState(prevState => ({
            hideComponent: !prevState.hideComponent
        })
    });

    render() {
        if (this.state.hideComponent === true) {return false;}

        return (
            <div className={`content`} onClick={() => this.closeThis}>
                YOUR CODE HERE
            </div>
        );
    }
}

The best way is set this two events to all of windows of your app:

GotKeyboardFocus
LostKeyboardFocus

in this way:

WiondowOfMyApp_GotKeyboardFocus(object sender, System.Windows.Input.KeyboardFocusChangedEventArgs e)
{
    windowThatShouldBeTopMost.TopMost = true;
}

WiondowOfMyApp_LostKeyboardFocus(object sender, System.Windows.Input.KeyboardFocusChangedEventArgs e)
{
    windowThatShouldBeTopMost.TopMost = false;
}

• and surely all of the windows that you wanted to be top, should be accessible from other windows of your app. in my case I have a base window and another some windows that should be top of my base window, so this was not bad to my base window has instance of each another windows.

try

time="12:12:12";
tt=time.split(":");
sec=tt[0]*3600+tt[1]*60+tt[2]*1;

The reason the code in your question does not authenticate is because you are sending the auth in the data object, not in the config, which will put it in the headers. Per the axios docs, the request method alias for post is:

axios.post(url[, data[, config]])

Therefore, for your code to work, you need to send an empty object for data:

var session_url = 'http://api_address/api/session_endpoint';
var username = 'user';
var password = 'password';
var basicAuth = 'Basic ' + btoa(username + ':' + password);
axios.post(session_url, {}, {
  headers: { 'Authorization': + basicAuth }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

The same is true for using the auth parameter mentioned by @luschn. The following code is equivalent, but uses the auth parameter instead (and also passes an empty data object):

var session_url = 'http://api_address/api/session_endpoint';
var uname = 'user';
var pass = 'password';
axios.post(session_url, {}, {
  auth: {
    username: uname,
    password: pass
  }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

You could use reinterprete_cast to check inheritance at compile time.

You can use setBounds(x, y, width, height) to specify the position and size of a GUI component if you set the layout to null. Then (x, y) is the coordinate of the upper-left corner of that component.

Easier method is window.location.href = "http://example.com/new_url";

But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database. You can do this easily following this code.

html form -

<form name="myForm" onsubmit="return validateForm()" method="POST" action="login.php" >         
    <input type="text" name="username" id="username" />
    <input type="password" name="password" id="password" />
    <input type="submit" name="submitBt"value="LogIn" />
</form>

javascript validation-

function validateForm(){
    var uname = document.forms["myForm"]["username"].value;
    var pass = document.forms["myForm"]["password"].value;

    if((!isEmpty(uname, "Log In")) && (!isEmpty(pass, "Password"))){

        return true;
    }else{
        return false;
    }
}

function isEmpty(elemValue, field){
    if((elemValue == "") || (elemValue == null)){
        alert("you can not have "+field+" field empty");
        return true;
    }else{
        return false;
    }
}

check if user in the database using php

<?php
    $con = mysqli_connect("localhost","root","1234","users");

    if(mysqli_connect_errno()){
        echo "Couldn't connect ".mysqli_connect_error();
    }else{
        //echo "connection successful <br />";
    }

    $uname_tb = $_POST['username'];
    $pass_tb = $_POST['password'];

    $query ="SELECT * FROM user";
    $result = mysqli_query($con,$query);

    while($row = mysqli_fetch_array($result)){
        if(($row['username'] == $uname_tb) && ($row['password'] == $pass_tb)){
            echo "Login Successful";
            header('Location: dashbord.php');
            exit();
        }else{
            echo "You are not in our database".mysqli_connect_error();
        }
    }
    mysqli_close($con);
?>

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

Try this one

UPDATE employee 
set EMPLOYEE.MAIDEN_NAME = 
  (SELECT ADD1 
   FROM EMPS 
   WHERE EMP_CODE=EMPLOYEE.EMP_CODE);
WHERE EMPLOYEE.EMP_CODE >='00' 
AND EMPLOYEE.EMP_CODE <='ZZ';

If all fails, simply put the DLL in the windows\system32 folder . The compiler will find it. Specify the DLL to load from with: DllImport("user32.dll"..., set EntryPoint = "my_unmanaged_function" to import your desired unmanaged function to your C# app:

 using System;
using System.Runtime.InteropServices;

class Example
{
   // Use DllImport to import the Win32 MessageBox function.

   [DllImport ("user32.dll", CharSet = CharSet.Auto)]
   public static extern int MessageBox 
      (IntPtr hWnd, String text, String caption, uint type);

   static void Main()
   {
      // Call the MessageBox function using platform invoke.
      MessageBox (new IntPtr(0), "Hello, World!", "Hello Dialog", 0);    
   }
}

This seems to be the best solution as it takes multiple parameters of the same name into consideration.

    function paramsToJSON(str) {
        var pairs = str.split('&');
        var result = {};
        pairs.forEach(function(pair) {
            pair = pair.split('=');
            var name = pair[0]
            var value = pair[1]
            if( name.length )
                if (result[name] !== undefined) {
                    if (!result[name].push) {
                        result[name] = [result[name]];
                    }
                    result[name].push(value || '');
                } else {
                    result[name] = value || '';
                }
        });
        return( result );
    }

<a href="index.html?x=1&x=2&x=3&y=blah">something</a>
paramsToJSON("x=1&x=2&x=3&y=blah"); 

console yields => {x: Array[3], y: "blah"} where x is an array as is proper JSON

I later decided to convert it to a jQuery plugin too...

$.fn.serializeURLParams = function() {
    var result = {};

    if( !this.is("a") || this.attr("href").indexOf("?") == -1 ) 
        return( result );

    var pairs = this.attr("href").split("?")[1].split('&');
    pairs.forEach(function(pair) {
        pair = pair.split('=');
        var name = decodeURI(pair[0])
        var value = decodeURI(pair[1])
        if( name.length )
            if (result[name] !== undefined) {
                if (!result[name].push) {
                    result[name] = [result[name]];
                }
                result[name].push(value || '');
            } else {
                result[name] = value || '';
            }
    });
    return( result )
}

<a href="index.html?x=1&x=2&x=3&y=blah">something</a>
$("a").serializeURLParams(); 

console yields => {x: Array[3], y: "blah"} where x is an array as is proper JSON

Now, the first will accept the parameters only but the jQuery plugin will take the whole url and return the serialized parameters.

You should use querySelectorAll. It returns NodeList, however querySelector returns only the first found element:

var deleteLink = document.querySelectorAll('.delete');

Then you would loop:

for (var i = 0; i < deleteLink.length; i++) {
    deleteLink[i].addEventListener('click', function(event) {
        if (!confirm("sure u want to delete " + this.title)) {
            event.preventDefault();
        }
    });
}

Also you should preventDefault only if confirm === false.

It's also worth noting that return false/true is only useful for event handlers bound with onclick = function() {...}. For addEventListening you should use event.preventDefault().

Demo: http://jsfiddle.net/Rc7jL/3/

ES6 version

You can make it a little cleaner (and safer closure-in-loop wise) by using Array.prototype.forEach iteration instead of for-loop:

var deleteLinks = document.querySelectorAll('.delete');

Array.from(deleteLinks).forEach(link => {
    link.addEventListener('click', function(event) {
        if (!confirm(`sure u want to delete ${this.title}`)) {
            event.preventDefault();
        }
    });
});

_{Example above uses Array.from and template strings from ES2015 standard.}

This is for the text form of a timestamp that can be used in your text files. (The title of the question was different in the past, so the introduction to this answer was changed to clarify how it could be interpreted as the time. [updated 2016-01-14])

You can get the timestamp as a string using the .now() or .utcnow() of the datetime.datetime:

>>> import datetime
>>> print datetime.datetime.utcnow()
2012-12-15 10:14:51.898000

The now differs from utcnow as expected -- otherwise they work the same way:

>>> print datetime.datetime.now()
2012-12-15 11:15:09.205000

You can render the timestamp to the string explicitly:

>>> str(datetime.datetime.now())
'2012-12-15 11:15:24.984000'

Or you can be even more explicit to format the timestamp the way you like:

>>> datetime.datetime.now().strftime("%A, %d. %B %Y %I:%M%p")
'Saturday, 15. December 2012 11:19AM'

If you want the ISO format, use the .isoformat() method of the object:

>>> datetime.datetime.now().isoformat()
'2013-11-18T08:18:31.809000'

You can use these in variables for calculations and printing without conversions.

>>> ts = datetime.datetime.now()
>>> tf = datetime.datetime.now()
>>> te = tf - ts
>>> print ts
2015-04-21 12:02:19.209915
>>> print tf
2015-04-21 12:02:30.449895
>>> print te
0:00:11.239980

mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(currentPlace,15)); This is will not have animation effect.

I'm calling scatter inside a loop and want each plot in a different color.

Based on that, and on your answer: It seems to me that you actually want n distinct colors for your datasets; you want to map the integer indices 0, 1, ..., n-1 to distinct RGB colors. Something like:

Here is the function to do it:

import matplotlib.pyplot as plt

def get_cmap(n, name='hsv'):
    '''Returns a function that maps each index in 0, 1, ..., n-1 to a distinct 
    RGB color; the keyword argument name must be a standard mpl colormap name.'''
    return plt.cm.get_cmap(name, n)

Usage in your pseudo-code snippet in the question:

cmap = get_cmap(len(data))
for i, (X, Y) in enumerate(data):
   scatter(X, Y, c=cmap(i))

I generated the figure in my answer with the following code:

import matplotlib.pyplot as plt

def get_cmap(n, name='hsv'):
    '''Returns a function that maps each index in 0, 1, ..., n-1 to a distinct 
    RGB color; the keyword argument name must be a standard mpl colormap name.'''
    return plt.cm.get_cmap(name, n)

def main():
    N = 30
    fig=plt.figure()
    ax=fig.add_subplot(111)   
    plt.axis('scaled')
    ax.set_xlim([ 0, N])
    ax.set_ylim([-0.5, 0.5])
    cmap = get_cmap(N)
    for i in range(N):
        rect = plt.Rectangle((i, -0.5), 1, 1, facecolor=cmap(i))
        ax.add_artist(rect)
    ax.set_yticks([])
    plt.show()

if __name__=='__main__':
    main()

Tested with both Python 2.7 & matplotlib 1.5, and with Python 3.5 & matplotlib 2.0. It works as expected.

I've actually resorted to a bit of trickery to deal with this at times. I developed a jQuery scrollbar widget where I encountered the problem that I don't know ahead of time if the scrollable content is a part of a hidden piece of markup or not. Here's what I did:

// try to grab the height of the elem
if (this.element.height() > 0) {
    var scroller_height = this.element.height();
    var scroller_width = this.element.width();

// if height is zero, then we're dealing with a hidden element
} else {
    var copied_elem = this.element.clone()
                      .attr("id", false)
                      .css({visibility:"hidden", display:"block", 
                               position:"absolute"});
    $("body").append(copied_elem);
    var scroller_height = copied_elem.height();
    var scroller_width = copied_elem.width();
    copied_elem.remove();
}

This works for the most part, but there's an obvious problem that can potentially come up. If the content you are cloning is styled with CSS that includes references to parent markup in their rules, the cloned content will not contain the appropriate styling, and will likely have slightly different measurements. To get around this, you can make sure that the markup you are cloning has CSS rules applied to it that do not include references to parent markup.

Also, this didn't come up for me with my scroller widget, but to get the appropriate height of the cloned element, you'll need to set the width to the same width of the parent element. In my case, a CSS width was always applied to the actual element, so I didn't have to worry about this, however, if the element doesn't have a width applied to it, you may need to do some kind of recursive traversal of the element's DOM ancestry to find the appropriate parent element's width.

Use the DEFAULT keyword:

$query = "INSERT INTO myTable VALUES (DEFAULT,'Fname', 'Lname', 'Website')";

Also, you can specify the columns, (which is better practice):

$query = "INSERT INTO myTable
          (fname, lname, website)
          VALUES
          ('fname', 'lname', 'website')";

Reference:

• http://dev.mysql.com/doc/refman/5.6/en/data-type-defaults.html

You can combine this all into one formula, but you need to use a regular IF first to find out if the VLOOKUP came back with something, then use your COUNTIF if it did.

=IF(ISERROR(VLOOKUP(B1,Sheet2!A1:A9,1,FALSE)),"Not there",COUNTIF(Sheet2!A1:A9,B1))

In this case, Sheet2-A1:A9 is the range I was searching, and Sheet1-B1 had the value I was looking for ("To retire" in your case).

dtypes is a Pandas Series. That means it contains index & values attributes. If you only need the column names:

headers = df.dtypes.index

it will return a list containing the column names of "df" dataframe.

Passing Parameters in Stored Procedure and calling it in C# Code behind as shown below?

SqlConnection conn = new SqlConnection(func.internalConnection);
var cmd = new SqlCommand("usp_CustomerPortalOrderDetails", conn);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.Parameters.Add("@CustomerId", SqlDbType.Int).Value = customerId;
cmd.Parameters.Add("@Qid", SqlDbType.VarChar).Value = qid;
conn.Open();

// Populate Production Panels
DataTable listCustomerJobDetails = new DataTable();
listCustomerJobDetails.Load(cmd.ExecuteReader());
conn.Close();

I like this better:

public String join(Collection<String> strCollection, String delimiter) {
    String joined = "";
    int noOfItems = 0;
    for (String item : strCollection) {
        joined += item;
        if (++noOfItems < strCollection.size())
            joined += delimiter;
    }
    return joined;
}

It is the neatest solution I have found so far. (Don't worry about the use of raw String objects instead of StringBuilder. Modern Java compilers use StringBuilder anyway, but this code is more readable).

I tried many solutions include Joseph Johnson's and Johan Stuyts's. But as a result I got a white space between content and keyboard on some devices (like Lenovo s820) in all cases. So I made some changes to their codes and finally got working solution.

My idea based on adding margin to top of content when keyboard is showing.

contentContainer.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds);
    int usableHeightNow = contentAreaOfWindowBounds.height();

    if (usableHeightNow != usableHeightPrevious) {

        int difference = usableHeightNow - usableHeightPrevious;

        if (difference < 0 && difference < -150) {
            keyboardShowed = true;
            rootViewLayout.topMargin -= difference + 30;
            rootViewLayout.bottomMargin += 30;
        }
        else if (difference < 0 && difference > -150){
            rootViewLayout.topMargin -= difference + 30;
        }
        else if (difference > 0 && difference > 150) {
            keyboardShowed = false;
            rootViewLayout.topMargin = 0;
            rootViewLayout.bottomMargin = 0;
        }

        rootView.requestLayout();

        Log.e("Bug Workaround", "Difference: " + difference);

        usableHeightPrevious = usableHeightNow;
}

As you can see, I add 30 px to difference because there is a small white space between top of the screen and content zone with margin. And I dont know whence it appears so I decided just make margins smaller and now it works exactly how I needed.

go to the AndroidManifest.xml and replace

android:theme="@style/AppTheme"

by 

android:theme="@android:style/Theme.Holo.Light.DarkActionBar"

Try do this:

EXEC @SelectedValue = GetMyInt

This should work if the date format is consistent:

select SUBSTRING_INDEX( subdateshow,"/",-1 ) from table 

When you say #include "foop.cpp", it is as if you had copied the entire contents of foop.cpp and pasted it into main.cpp.

So when you compile main.cpp, the compiler emits a main.obj that contains the executable code for two functions: main and foo.

When you compile foop.cpp itself, the compiler emits a foop.obj that contains the executable code for function foo.

When you link them together, the compiler sees two definitions for function foo (one from main.obj and the other from foop.obj) and complains that you have multiple definitions.

You need to define MyMessageBox before User -- because User include object of MyMessageBox by value (and so compiler should know its size).

Also you'll need to forward declare User befor MyMessageBox -- because MyMessageBox include member of User* type.

In swift you can do it like this:

let isPointInFrame = frame.contains(point)

"frame" is a CGRect and "point" is a CGPoint

import java.lang.String; //contains equalsIgnoreCase()
/*
*
*/
String s1 = "Hello";
String s2 = "hello";

if (s1.equalsIgnoreCase(s2)) {
System.out.println("hai");
} else {
System.out.println("welcome");
}

Now it will output : hai

Modification of a Collection while iterating through that Collection using an Iterator is not permitted by most of the Collection classes. The Java library calls an attempt to modify a Collection while iterating through it a "concurrent modification". That unfortunately suggests the only possible cause is simultaneous modification by multiple threads, but that is not so. Using only one thread it is possible to create an iterator for the Collection (using Collection.iterator(), or an enhanced for loop), start iterating (using Iterator.next(), or equivalently entering the body of the enhanced for loop), modify the Collection, then continue iterating.

To help programmers, some implementations of those Collection classes attempt to detect erroneous concurrent modification, and throw a ConcurrentModificationException if they detect it. However, it is in general not possible and practical to guarantee detection of all concurrent modifications. So erroneous use of the Collection does not always result in a thrown ConcurrentModificationException.

The documentation of ConcurrentModificationException says:

This exception may be thrown by methods that have detected concurrent modification of an object when such modification is not permissible...

Note that this exception does not always indicate that an object has been concurrently modified by a different thread. If a single thread issues a sequence of method invocations that violates the contract of an object, the object may throw this exception...

Note that fail-fast behavior cannot be guaranteed as it is, generally speaking, impossible to make any hard guarantees in the presence of unsynchronized concurrent modification. Fail-fast operations throw ConcurrentModificationException on a best-effort basis.

Note that

• the exception may be throw, not must be thrown
• different threads are not required
• throwing the exception cannot be guaranteed
• throwing the exception is on a best-effort basis
• throwing the exception happens when the concurrent modification is detected, not when it is caused

The documentation of the HashSet, HashMap, TreeSet and ArrayList classes says this:

The iterators returned [directly or indirectly from this class] are fail-fast: if the [collection] is modified at any time after the iterator is created, in any way except through the iterator's own remove method, the Iterator throws a ConcurrentModificationException. Thus, in the face of concurrent modification, the iterator fails quickly and cleanly, rather than risking arbitrary, non-deterministic behavior at an undetermined time in the future.

Note that the fail-fast behavior of an iterator cannot be guaranteed as it is, generally speaking, impossible to make any hard guarantees in the presence of unsynchronized concurrent modification. Fail-fast iterators throw ConcurrentModificationException on a best-effort basis. Therefore, it would be wrong to write a program that depended on this exception for its correctness: the fail-fast behavior of iterators should be used only to detect bugs.

Note again that the behaviour "cannot be guaranteed" and is only "on a best-effort basis".

The documentation of several methods of the Map interface say this:

Non-concurrent implementations should override this method and, on a best-effort basis, throw a ConcurrentModificationException if it is detected that the mapping function modifies this map during computation. Concurrent implementations should override this method and, on a best-effort basis, throw an IllegalStateException if it is detected that the mapping function modifies this map during computation and as a result computation would never complete.

Note again that only a "best-effort basis" is required for detection, and a ConcurrentModificationException is explicitly suggested only for the non concurrent (non thread-safe) classes.

Debugging ConcurrentModificationException

So, when you see a stack-trace due to a ConcurrentModificationException, you can not immediately assume that the cause is unsafe multi-threaded access to a Collection. You must examine the stack-trace to determine which class of Collection threw the exception (a method of the class will have directly or indirectly thrown it), and for which Collection object. Then you must examine from where that object can be modified.

• The most common cause is modification of the Collection within an enhanced for loop over the Collection. Just because you do not see an Iterator object in your source code does not mean there is no Iterator there! Fortunately, one of the statements of the faulty for loop will usually be in the stack-trace, so tracking down the error is usually easy.
• A trickier case is when your code passes around references to the Collection object. Note that unmodifiable views of collections (such as produced by Collections.unmodifiableList()) retain a reference to the modifiable collection, so iteration over an "unmodifiable" collection can throw the exception (the modification has been done elsewhere). Other views of your Collection, such as sub lists, Map entry sets and Map key sets also retain references to the original (modifiable) Collection. This can be a problem even for a thread-safe Collection, such as CopyOnWriteList; do not assume that thread-safe (concurrent) collections can never throw the exception.
• Which operations can modify a Collection can be unexpected in some cases. For example, LinkedHashMap.get() modifies its collection.
• The hardest cases are when the exception is due to concurrent modification by multiple threads.

Programming to prevent concurrent modification errors

When possible, confine all references to a Collection object, so its is easier to prevent concurrent modifications. Make the Collection a private object or a local variable, and do not return references to the Collection or its iterators from methods. It is then much easier to examine all the places where the Collection can be modified. If the Collection is to be used by multiple threads, it is then practical to ensure that the threads access the Collection only with appropriate synchonization and locking.

You haven't mentioned the DBMS. Assuming you are using MS SQL-Server, I've found a T-SQL Error message that is self-explanatory:

"An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference"

http://www.sql-server-performance.com/

And an example that it is possible in a subquery.

Show all customers and smallest order for those who have 5 or more orders (and NULL for others):

SELECT a.lastname
     , a.firstname
     , ( SELECT MIN( o.amount )
         FROM orders o
         WHERE a.customerid = o.customerid
           AND COUNT( a.customerid ) >= 5
        )
        AS smallestOrderAmount
FROM account a
GROUP BY a.customerid
       , a.lastname
       , a.firstname ;

UPDATE.

The above runs in both SQL-Server and MySQL but it doesn't return the result I expected. The next one is more close. I guess it has to do with that the field customerid, GROUPed BY and used in the query-subquery join is in the first case PRIMARY KEY of the outer table and in the second case it's not.

Show all customer ids and number of orders for those who have 5 or more orders (and NULL for others):

SELECT o.customerid
     , ( SELECT COUNT( o.customerid )
         FROM account a
         WHERE a.customerid = o.customerid
           AND COUNT( o.customerid ) >= 5
        )
        AS cnt
FROM orders o
GROUP BY o.customerid ;

The following code is my WCF named pipes solution to register a single-instance application. It's nice because it also raises an event when another instance attempts to start, and receives the command line of the other instance.

It's geared toward WPF because it uses the System.Windows.StartupEventHandler class, but this could be easily modified.

This code requires a reference to PresentationFramework, and System.ServiceModel.

Usage:

class Program
{
    static void Main()
    {
        var applicationId = new Guid("b54f7b0d-87f9-4df9-9686-4d8fd76066dc");

        if (SingleInstanceManager.VerifySingleInstance(applicationId))
        {
            SingleInstanceManager.OtherInstanceStarted += OnOtherInstanceStarted;

            // Start the application
        }
    }

    static void OnOtherInstanceStarted(object sender, StartupEventArgs e)
    {
        // Do something in response to another instance starting up.
    }
}

In the first case you are declaring "int a" as a local variable(as declared inside a method) and local varible do not get default value.

But instance variable are given default value both for static and non-static.

Default value for instance variable:

int = 0

float,double = 0.0

reference variable = null

char = 0 (space character)

boolean = false

use ArrayUtils.addAll(T[], T...):

import org.apache.commons.lang3.ArrayUtils;

AnyObject[] array1 = ...;
AnyObject[] array2 = ...;
AnyObject[] mergedArray = ArrayUtils.addAll(array1, array2);

/* The algorithm is from the book "Discrete Mathematics and Its
   Applications 5th Edition" by Kenneth H. Rosen.

int modular(int base, unsigned int exp, unsigned int mod)
{
    int x = 1;
    int power = base % mod;

    for (int i = 0; i < sizeof(int) * 8; i++) {
        int least_sig_bit = 0x00000001 & (exp >> i);
        if (least_sig_bit)
            x = (x * power) % mod;
        power = (power * power) % mod;
    }

    return x;
}

Try this regex:

^(\+?\d{1,4}[\s-])?(?!0+\s+,?$)\d{10}\s*,?$

Explanation of the regex using Perl's YAPE is as below:

Use the following code to check if a folder exists. It works on both Windows & Linux platforms.

#include <stdio.h>
#include <sys/stat.h>

int main(int argc, char* argv[])
{
    const char* folder;
    //folder = "C:\\Users\\SaMaN\\Desktop\\Ppln";
    folder = "/tmp";
    struct stat sb;

    if (stat(folder, &sb) == 0 && S_ISDIR(sb.st_mode)) {
        printf("YES\n");
    } else {
        printf("NO\n");
    }
}

If you have GDAL/OGR compiled with the against the Expat library, you can use the XLSX driver to read .xlsx files, and run SQL expressions from a command prompt. For example, from a osgeo4w shell in the same directory as the spreadsheet, use the ogrinfo utility:

ogrinfo -dialect sqlite -sql "SELECT name, count(*) FROM sheet1 GROUP BY name" Book1.xlsx

will run a SQLite query on sheet1, and output the query result in an unusual form:

INFO: Open of `Book1.xlsx'
      using driver `XLSX' successful.

Layer name: SELECT
Geometry: None
Feature Count: 36
Layer SRS WKT:
(unknown)
name: String (0.0)
count(*): Integer (0.0)
OGRFeature(SELECT):0
  name (String) = Red
  count(*) (Integer) = 849

OGRFeature(SELECT):1
  name (String) = Green
  count(*) (Integer) = 265
...

Or run the same query using ogr2ogr to make a simple CSV file:

$ ogr2ogr -f CSV out.csv -dialect sqlite \
          -sql "SELECT name, count(*) FROM sheet1 GROUP BY name" Book1.xlsx

$ cat out.csv
name,count(*)
Red,849
Green,265
...

To do similar with older .xls files, you would need the XLS driver, built against the FreeXL library, which is not really common (e.g. not from OSGeo4w).

This is an old question, but I'd say none of the answers really fits the OP's question. All he wanted/needed to do is this:

char c = std::fgetc(fp);
std::strcpy(buffer, &c);

The relevant aspect here is the fact, that the second argument of strcpy() doesn't need to be a char array / c-string. In fact, none of the arguments is a char or char array at all. They are both char pointers:

strcpy(char* dest, const char* src);

dest : A non-const char pointer

Its value has to be the memory address of an element of a writable char array (with at least one more element after that).

src : A const char pointer

Its value can be the address of a single char, or of an element in a char array. That array must contain the special character \0 within its remaining elements (starting with src), to mark the end of the c-string that should be copied.

This is how I solved my problem

Let's assume the upstream branch is the one that you forked from and origin is your repo and you want to send an MR/PR to the upstream branch.

You already have let's say about 4 commits and you are getting Updates were rejected because the tip of your current branch is behind.

Here is what I did

First, squash all your 4 commits

git rebase -i HEAD~4

You'll get a list of commits with pick written on them. (opened in an editor)

example

pick fda59df commit 1
pick x536897 commit 2
pick c01a668 commit 3
pick c011a77 commit 4

to

pick fda59df commit 1
squash x536897 commit 2
squash c01a668 commit 3
squash c011a77 commit 4

After that, you can save your combined commit

Next

You'll need to stash your commit

Here's how

git reset --soft HEAD~1
git stash

now rebase with your upstream branch

git fetch upstream beta && git rebase upstream/beta

Now pop your stashed commit

git stash pop

commit these changes and push them

git add -A
git commit -m "[foo] - foobar commit"
git push origin fix/#123 -f

Using the title attribute:

<a href="#" title="Tooltip here">Link</a>

In my case only deleting of the local version and re checkout of fresh copy was a solution.

The basic setup of decorators is like this:

InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);

The key issue in this snippet is the value of encoding. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.

For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.

Most network protocols use a header or other metadata to explicitly note the character encoding.

In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.

Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!

1. Install Style Loader and CSS Loader:

   npm install --save-dev style-loader
   npm install --save-dev css-loader
   

2. Configure webpack

   module: {
           loaders: [
               {
                   test: /\.css$/,
                   loader: 'style-loader'
               }, {
                   test: /\.css$/,
                   loader: 'css-loader',
                   query: {
                       modules: true,
                       localIdentName: '[name]__[local]___[hash:base64:5]'
                   }
               }
           ]
       }
   

You can easily append to the end of a file, by using the redirection char twice (>>).

This will copy source.txt to destination.txt, overwriting destination in the process:

type source.txt > destination.txt

This will copy source.txt to destination.txt, appending to destination in the process:

type source.txt >> destination.txt

I can't comment on how efficient this is, but here's a solution:

applyToGivenRow = @(func, matrix) @(row) func(matrix(row, :))
applyToRows = @(func, matrix) arrayfun(applyToGivenRow(func, matrix), 1:size(matrix,1))'

% Example
myMx = [1 2 3; 4 5 6; 7 8 9];
myFunc = @sum;

applyToRows(myFunc, myMx)

Type safety means that the compiler will validate types while compiling, and throw an error if you try to assign the wrong type to a variable.

Some simple examples:

// Fails, Trying to put an integer in a string
String one = 1;
// Also fails.
int foo = "bar";

This also applies to method arguments, since you are passing explicit types to them:

int AddTwoNumbers(int a, int b)
{
    return a + b;
}

If I tried to call that using:

int Sum = AddTwoNumbers(5, "5");

The compiler would throw an error, because I am passing a string ("5"), and it is expecting an integer.

In a loosely typed language, such as javascript, I can do the following:

function AddTwoNumbers(a, b)
{
    return a + b;
}

if I call it like this:

Sum = AddTwoNumbers(5, "5");

Javascript automaticly converts the 5 to a string, and returns "55". This is due to javascript using the + sign for string concatenation. To make it type-aware, you would need to do something like:

function AddTwoNumbers(a, b)
{
    return Number(a) + Number(b);
}

Or, possibly:

function AddOnlyTwoNumbers(a, b)
{
    if (isNaN(a) || isNaN(b))
        return false;
    return Number(a) + Number(b);
}

if I call it like this:

Sum = AddTwoNumbers(5, " dogs");

Javascript automatically converts the 5 to a string, and appends them, to return "5 dogs".

Not all dynamic languages are as forgiving as javascript (In fact a dynamic language does not implicity imply a loose typed language (see Python)), some of them will actually give you a runtime error on invalid type casting.

While its convenient, it opens you up to a lot of errors that can be easily missed, and only identified by testing the running program. Personally, I prefer to have my compiler tell me if I made that mistake.

Now, back to C#...

C# supports a language feature called covariance, this basically means that you can substitute a base type for a child type and not cause an error, for example:

 public class Foo : Bar
 {
 }

Here, I created a new class (Foo) that subclasses Bar. I can now create a method:

 void DoSomething(Bar myBar)

And call it using either a Foo, or a Bar as an argument, both will work without causing an error. This works because C# knows that any child class of Bar will implement the interface of Bar.

However, you cannot do the inverse:

void DoSomething(Foo myFoo)

In this situation, I cannot pass Bar to this method, because the compiler does not know that Bar implements Foo's interface. This is because a child class can (and usually will) be much different than the parent class.

Of course, now I've gone way off the deep end and beyond the scope of the original question, but its all good stuff to know :)

Another mac solution similar to osxfuse is to just use Transmit FTP client from Panic Software, which allows you to mount a remote folder as a local disk. It supports SFTP, which is very secure.

If you have no permissions or access to the command line directly, you can do e.g. one of the following:

1. Create a job with shell/batch step that will trigger a restart from the Jenkins installation folder
2. Install/update some plugin while checking "restart after installation" (at least this works in old versions)

Both above are hacks, but I actively used them in a very restricted environment where no one wanted me to restart Jenkins, huh.

check out distributionUrl setting in gradle-wrapper.properties. I changed https to http, then my problem was solved.

As per java doc's

Hashtable and Collections.synchronizedMap(new HashMap()) are synchronized. But ConcurrentHashMap is "concurrent".

A concurrent collection is thread-safe, but not governed by a single exclusion lock.

In the particular case of ConcurrentHashMap, it safely permits any number of concurrent reads as well as a tunable number of concurrent writes. "Synchronized" classes can be useful when you need to prevent all access to a collection via a single lock, at the expense of poorer scalability.

In other cases in which multiple threads are expected to access a common collection, "concurrent" versions are normally preferable. And unsynchronized collections are preferable when either collections are unshared, or are accessible only when holding other locks.

This query gets the columns name

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'YourTableName'

And this one gets the count

SELECT Count(*) FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'YourTableName'

If you can have your quote delimiter be double quotes, then this is a duplicate of Example JavaScript code to parse CSV data.

You can either translate all single-quotes to double-quotes first:

string = string.replace( /'/g, '"' );

...or you can edit the regex in that question to recognize single-quotes instead of double-quotes:

// Quoted fields.
"(?:'([^']*(?:''[^']*)*)'|" +

However, this assumes certain markup that is not clear from your question. Please clarify what all the various possibilities of markup can be, per my comment on your question.

The following function should do what you want exactly:

hush=function(code){
  sink("NUL") # use /dev/null in UNIX
  tmp = code
  sink()
  return(tmp)
}

For example with the function here:

foo=function(){
  print("BAR!")
  return(42)
}

running

x = hush(foo())

Will assign 42 to x but will not print "BAR!" to STDOUT

Note than in a UNIX OS you will need to replace "NUL" with "/dev/null"

We can use java streams to implement this in O(sqrt(n)); Consider that noneMatch is a shortCircuiting method that stops the operation when finds it unnecessary for determining the result:

Scanner in = new Scanner(System.in);
int n = in.nextInt();
System.out.println(n == 2 ? "Prime" : IntStream.rangeClosed(2, ((int)(Math.sqrt(n)) + 1)).noneMatch(a -> n % a == 0) ? "Prime" : "Not Prime");

I simply used new java version and it worked for me.

You can also remove the line

  require: 'ngModel',

if you don't need ngModel in this directive. Removing ngModel will allow you to make a directive without thatngModel error.

Doing this asynchronously is quite easy. It's particularly useful if you're concerned for blocking the thread (likely).

const fs = require('fs');
const fileName = './file.json';
const file = require(fileName);
    
file.key = "new value";
    
fs.writeFile(fileName, JSON.stringify(file), function writeJSON(err) {
  if (err) return console.log(err);
  console.log(JSON.stringify(file));
  console.log('writing to ' + fileName);
});

The caveat is that json is written to the file on one line and not prettified. ex:

{
  "key": "value"
}

will be...

{"key": "value"}

To avoid this, simply add these two extra arguments to JSON.stringify

JSON.stringify(file, null, 2)

null - represents the replacer function. (in this case we don't want to alter the process)

2 - represents the spaces to indent.

If you have virtualmin try to comment out these lines in your apache configuration in /etc/apache2/sites-available

  #RemoveHandler .php
  #RemoveHandler .php7.0
  #php_admin_value engine Off

if your SQL query is this

SELECT id,name,roll FROM student WHERE name='Amit' AND roll='7'

then rawQuery will be

String query="SELECT id, name, roll FROM student WHERE name = ? AND roll = ?";
String[] selectionArgs = {"Amit","7"} 
db.rawQuery(query, selectionArgs);

For Kotling here is what I used lately:

// src/main/com.blabla/ShellApplication.kt

/**
 * Main entry point for the shell application.
 */
@SpringBootApplication
public class ShellApplication : CommandLineRunner {
    companion object {
        @JvmStatic
        fun main(args: Array<String>) {
            val application = SpringApplication(ShellApplication::class.java)
            application.webApplicationType = WebApplicationType.NONE
            application.run(*args);
        }
    }

    override fun run(vararg args: String?) {}
}

// src/main/com.blabla/command/CustomCommand.kt

@ShellComponent
public class CustomCommand {
    private val logger = KotlinLogging.logger {}

    @ShellMethod("Import, create and update data from CSV")
    public fun importCsv(@ShellOption() file: String) {
        logger.info("Hi")
    }
}

And everything boot normally ending up with a shell with my custom command available.

The issue with the conversion (the reason it's giving you a ffffff at the end) is because your hex integer (that you are using the & binary operator with) is interpreted as being signed. Cast it to an unsigned integer, and you'll be fine.

Hack grep's color function, and count how many color tags it prints out:

        }

        public void onFinish() {

            txtcounter.setText(" TimeOut  ");
            Main2Activity.ShowPayment = false;
            EventBus.getDefault().post("go-main");

        }

    }.start();

For me in datetimepicker jquery plugin format:'d/m/Y' option is worked

$("#dobDate").datetimepicker({
lang:'en',
timepicker:false,
autoclose: true,
format:'d/m/Y',
onChangeDateTime:function( ct ){
   $(".xdsoft_datetimepicker").hide();
}
});

When I got the same error on my machine ("connection is refused"), the reason was that I had defined the following on the server side:

 Naming.rebind("rmi://localhost:8080/AddService"
   ,addService); 

Thus the server binds both the IP = 127.0.0.1 and the port 8080.

But on the client side I had used:

AddServerInterface st = (AddServerInterface)Naming.lookup("rmi://localhost"
                        +"/AddService");

Thus I forgot to add the port number after the localhost, so I rewrote the above command and added the port number 8080 as follows:

AddServerInterface st = (AddServerInterface)Naming.lookup("rmi://localhost:8080"
                        +"/AddService");

and everything worked fine.

Here is my 3 cents ...
This demonstrates explicit json serialization for a tree-like python object.
Note: If you actually wanted some code like this you could use the twisted FilePath class.

import json, sys, os

class File:
    def __init__(self, path):
        self.path = path

    def isdir(self):
        return os.path.isdir(self.path)

    def isfile(self):
        return os.path.isfile(self.path)

    def children(self):        
        return [File(os.path.join(self.path, f)) 
                for f in os.listdir(self.path)]

    def getsize(self):        
        return os.path.getsize(self.path)

    def getModificationTime(self):
        return os.path.getmtime(self.path)

def _default(o):
    d = {}
    d['path'] = o.path
    d['isFile'] = o.isfile()
    d['isDir'] = o.isdir()
    d['mtime'] = int(o.getModificationTime())
    d['size'] = o.getsize() if o.isfile() else 0
    if o.isdir(): d['children'] = o.children()
    return d

folder = os.path.abspath('.')
json.dump(File(folder), sys.stdout, default=_default)

The basic problem here is that you are mistaking System.Environment.Exit for return.

I personally dislike the "pass by reference" functionality offered by various programming languages. Perhaps that's because I am just discovering the concepts of functional programming, but I always get goosebumps when I see functions that cause side effects (like manipulating parameters passed by reference). I personally strongly embrace the "single responsibility" principle.

IMHO, a function should return just one result/value using the return keyword. Instead of modifying a parameter/argument, I would just return the modified parameter/argument value and leave any desired reassignments up to the calling code.

But sometimes (hopefully very rarely), it is necessary to return two or more result values from the same function. In that case, I would opt to include all those resulting values in a single structure or object. Again, processing any reassignments should be up to the calling code.

Example:

Suppose passing parameters would be supported by using a special keyword like 'ref' in the argument list. My code might look something like this:

//The Function
function doSomething(ref value) {
    value = "Bar";
}

//The Calling Code
var value = "Foo";
doSomething(value);
console.log(value); //Bar

Instead, I would actually prefer to do something like this:

//The Function
function doSomething(value) {
    value = "Bar";
    return value;
}

//The Calling Code:
var value = "Foo";
value = doSomething(value); //Reassignment
console.log(value); //Bar

When I would need to write a function that returns multiple values, I would not use parameters passed by reference either. So I would avoid code like this:

//The Function
function doSomething(ref value) {
    value = "Bar";

    //Do other work
    var otherValue = "Something else";

    return otherValue;
}

//The Calling Code
var value = "Foo";
var otherValue = doSomething(value);
console.log(value); //Bar
console.log(otherValue); //Something else

Instead, I would actually prefer to return both new values inside an object, like this:

//The Function
function doSomething(value) {
    value = "Bar";

    //Do more work
    var otherValue = "Something else";

    return {
        value: value,
        otherValue: otherValue
    };
}

//The Calling Code:
var value = "Foo";
var result = doSomething(value);
value = result.value; //Reassignment
console.log(value); //Bar
console.log(result.otherValue);

These code examples are quite simplified, but it roughly demonstrates how I personally would handle such stuff. It helps me to keep various responsibilities in the correct place.

Happy coding. :)

Starting from Rob's answer, I am currently using the following syntax.Since the question has received a lot of attention,I decided to share it with you :

var requrl = '@Url.Action("Action", "Controller", null, Request.Url.Scheme, null)';
  $.ajax({
   type: "POST",
   url: requrl,
   data: "{queryString:'" + searchVal + "'}",
   contentType: "application/json; charset=utf-8",
   dataType: "html",
   success: function (data) {
   alert("here" + data.d.toString());
   }
  });

OK, this is a bad thing to be doing. Don't mock a list; instead, mock the individual objects inside the list. See Mockito: mocking an arraylist that will be looped in a for loop for how to do this.

Also, why are you using PowerMock? You don't seem to be doing anything that requires PowerMock.

But the real cause of your problem is that you are using when on two different objects, before you complete the stubbing. When you call when, and provide the method call that you are trying to stub, then the very next thing you do in either Mockito OR PowerMock is to specify what happens when that method is called - that is, to do the thenReturn part. Each call to when must be followed by one and only one call to thenReturn, before you do any more calls to when. You made two calls to when without calling thenReturn - that's your error.

Dumping a database with a specific encoding and try to restore it on another database with a different encoding could result in data corruption. Data encoding must be set BEFORE any data is inserted into the database.

Check this : When copying any other database, the encoding and locale settings cannot be changed from those of the source database, because that might result in corrupt data.

And this : Some locale categories must have their values fixed when the database is created. You can use different settings for different databases, but once a database is created, you cannot change them for that database anymore. LC_COLLATE and LC_CTYPE are these categories. They affect the sort order of indexes, so they must be kept fixed, or indexes on text columns would become corrupt. (But you can alleviate this restriction using collations, as discussed in Section 22.2.) The default values for these categories are determined when initdb is run, and those values are used when new databases are created, unless specified otherwise in the CREATE DATABASE command.

I would rather rebuild everything from the begining properly with a correct local encoding on your debian OS as explained here :

su root

Reconfigure your local settings :

dpkg-reconfigure locales

Choose your locale (like for instance for french in Switzerland : fr_CH.UTF8)

Uninstall and clean properly postgresql :

apt-get --purge remove postgresql\*
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

Re-install postgresql :

aptitude install postgresql-9.1 postgresql-contrib-9.1 postgresql-doc-9.1

Now any new database will be automatically be created with correct encoding, LC_TYPE (character classification), and LC_COLLATE (string sort order).

Use DateFormat.getDateInstance(int style, Locale locale) instead of creating your own patterns with SimpleDateFormat.

You could embed the '' default in your regex by adding |$:

>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''

Also works with re.search pointed out by others:

>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''

In the Heroku documentation; Getting started whit rails 4, they say:

You will also need to remove the username field in your database.yml if there is one so: In file config/database.yml remove: username: myapp

Then you just delete that line in "development:", if you don't pg tells to the database that works under role "myapp"

This line tells rails that the database myapp_development should be run under a role of myapp. Since you likely don’t have this role in your database we will remove it. With the line remove Rails will try to access the database as user who is currently logged into the computer.

Also remember to create the database for development:

$createdb myapp_development

Repleace "myapp" for your app name

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

When you store something in an array , its size needs to be known (since array indexing relies on the size). Per the C++ standard It is unspecified whether or not a reference requires storage, as a result indexing an array of references would not be possible.

Another solution is to search for mvc in nuget (right click on your MVC project in visual studio and select "Manage Nuget Packages").

This will show you the version currently installed -

And it'll also allow you to update the MVC version -

There is no need for any External libraries, the JRE System libraries provide all you need.

I am infering that you have a org.w3c.dom.Document object you would like to write to a file

To do that, you use a javax.xml.transform.Transformer:

import org.w3c.dom.Document

import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.stream.StreamResult; 

public class XMLWriter {
    public static void writeDocumentToFile(Document document, File file) {

        // Make a transformer factory to create the Transformer
        TransformerFactory tFactory = TransformerFactory.newInstance();

        // Make the Transformer
        Transformer transformer = tFactory.newTransformer();

        // Mark the document as a DOM (XML) source
        DOMSource source = new DOMSource(document);

        // Say where we want the XML to go
        StreamResult result = new StreamResult(file);

        // Write the XML to file
        transformer.transform(source, result);
    }
}

I have wrote a generic function in which you can pass context, icon is id drawable/mipmap image icon and new color which you need for that icon.

This function returns a drawable.

public static Drawable changeDrawableColor(Context context,int icon, int newColor) {
    Drawable mDrawable = ContextCompat.getDrawable(context, icon).mutate(); 
    mDrawable.setColorFilter(new PorterDuffColorFilter(newColor, PorterDuff.Mode.SRC_IN)); 
    return mDrawable;
} 

changeDrawableColor(getContext(),R.mipmap.ic_action_tune, Color.WHITE);

Basic and simple.

In your adapter simply use this.

((YourParentClass) context).functionToRun();

Change your table declaration to:

<table style="border: 1px dashed; width: 500px;">

Here is the sample in action: http://jsfiddle.net/kc48k/

A statement contains a keyword.

An expression does not contain a keyword.

print "hello" is statement, because print is a keyword.

"hello" is an expression, but list compression is against this.

The following is an expression statement, and it is true without list comprehension:

(x*2 for x in range(10))

User.hasMany(Post, {foreignKey: 'user_id'})
Post.belongsTo(User, {foreignKey: 'user_id'})

Post.find({ where: { ...}, include: [User]})

Which will give you

SELECT
  `posts`.*,
  `users`.`username` AS `users.username`, `users`.`email` AS `users.email`,
  `users`.`password` AS `users.password`, `users`.`sex` AS `users.sex`,
  `users`.`day_birth` AS `users.day_birth`,
  `users`.`month_birth` AS `users.month_birth`,
  `users`.`year_birth` AS `users.year_birth`, `users`.`id` AS `users.id`,
  `users`.`createdAt` AS `users.createdAt`,
  `users`.`updatedAt` AS `users.updatedAt`
FROM `posts`
  LEFT OUTER JOIN `users` AS `users` ON `users`.`id` = `posts`.`user_id`;

The query above might look a bit complicated compared to what you posted, but what it does is basically just aliasing all columns of the users table to make sure they are placed into the correct model when returned and not mixed up with the posts model

Other than that you'll notice that it does a JOIN instead of selecting from two tables, but the result should be the same

    var outerHTML = function(el){
      var clone = el.cloneNode(true);
      temp_container.appendChild(clone);
      outerhtml = temp_container.innerHTML;
      temp_container.removeChild(clone);
      return outerhtml;

If you want to change the size of plot the use arg figsize

df.groupby(['NFF', 'ABUSE']).size().unstack()
      .plot(kind='bar', stacked=True, figsize=(15, 5))

The above responses are the better, but just for completeness, when you are in a component you can access the history object inside the VueRouter with: this.$router.history. That means we can listen to changes with:

this.$router.listen((newLocation) =>{console.log(newLocation);})

I think this is mainly useful when used along with this.$router.currentRoute.path You can check what I am talking about placing a debugger

Have you tried renaming the new version of your CSS to CSSv2.css and then directing your page to use that? If that solves the stale-file issue, then you're just experiencing non-refreshing files. If not, you've got bigger issues.

Looks like I'm late to the game, but this is a common question...

This is probably the code you want.

Please note that this code is in the public domain, from Usenet, MSDN, and the Excellerando blog.

Public Function ComputerName() As String
'' Returns the host name

'' Uses late-binding: bad for performance and stability, useful for 
'' code portability. The correct declaration is:

'   Dim objNetwork  As IWshRuntimeLibrary.WshNetwork
'   Set objNetwork = New IWshRuntimeLibrary.WshNetwork

    Dim objNetwork As Object
    Set objNetwork = CreateObject("WScript.Network")

    ComputerName = objNetwork.ComputerName
    
    Set objNetwork = Nothing

End Function

You'll probably need this, too:

Public Function UserName(Optional WithDomain As Boolean = False) As String
'' Returns the user's network name

'' Uses late-binding: bad for performance and stability, useful for
'' code portability. The correct declaration is:

'   Dim objNetwork  As IWshRuntimeLibrary.WshNetwork
'   Set objNetwork = New IWshRuntimeLibrary.WshNetwork


    Dim objNetwork As Object
    Set objNetwork = CreateObject("WScript.Network")

    If WithDomain Then
        UserName = objNetwork.UserDomain & "\" & objNetwork.UserName
    Else
        UserName = objNetwork.UserName
    End If
    
    Set objNetwork = Nothing

End Function

If the adb connection is ever lost:

Make sure that your host is still connected to the same Wi-Fi network your Android device is. Reconnect by executing the "adb connect IP" step. (IP is obviously different when you change location.) Or if that doesn't work, reset your adb host: adb kill-server and then start over from the beginning.

There is a quick way I found. Go to your .git folder, open the HEAD file and change whatever branch you were on back to master. E.g. ref: refs/heads/master

...but... wouldn't it be better to adjust the image size on the server side rather than transmitting the bytes to the browser and doing it there?

When I say adjust the image size, I don't mean set the height and width in the HTML image tag. If you do that, you are still shipping a large number of bytes from server to client. I mean, actually manipulate the image itself server side.

I have .NET C# code here that takes that approach, but there must be a php way to do it too: http://ifdefined.com/www/gallery.html

Also, by doing it server side, that opens up the possibility of doing the adjustment just once and then saving the adjusted image, which would be very fast.

The obvious solution is a function to map a digit to a list of keys, and then a function that would generate the possible combinations:

The first is obvious, the second is more problematic because you have around 3^number of digits combinations, which can be a very large number.

One way to do it is to look at each possibility for digit matching as a digit in a number (on base 4) and implement something close to a counter (jumping over some instances, since there are usually less than 4 letters mappable to a digit).

The more obvious solutions would be nested loops or recursion, which are both less elegant, but in my opinion valid.

Another thing for which care must be taken is to avoid scalability issues (e.g. keeping the possibilities in memory, etc.) since we are talking about a lot of combinations.

P.S. Another interesting extension of the question would be localization.

testCompile is deprecated. Gradle 7 compatible:

dependencies {
...
   testImplementation 'junit:junit:4.13'
}

and if you use the default folder structure (src/test/java/...) the test section is simply:

test {
    useJUnit()
}

Finally:

gradlew clean test

Using the csv module:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = list(reader)

print(data)

Output:

[['This is the first line', 'Line1'], ['This is the second line', 'Line2'], ['This is the third line', 'Line3']]

If you need tuples:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = [tuple(row) for row in reader]

print(data)

Output:

[('This is the first line', 'Line1'), ('This is the second line', 'Line2'), ('This is the third line', 'Line3')]

Old Python 2 answer, also using the csv module:

import csv

    your_list = list(reader)

print your_list
# [['This is the first line', 'Line1'],
#  ['This is the second line', 'Line2'],
#  ['This is the third line', 'Line3']]

from php 7 u can use

I am wondering if anyone uses (2)?

Yes. But rarely for a sound reason (IMO).

And people get burned because they used ArrayList when they should have used List:

• Utility methods like Collections.singletonList(...) or Arrays.asList(...) don't return an ArrayList.

• Methods in the List API don't guarantee to return a list of the same type.

For example of someone getting burned, in https://stackoverflow.com/a/1481123/139985 the poster had problems with "slicing" because ArrayList.sublist(...) doesn't return an ArrayList ... and he had designed his code to use ArrayList as the type of all of his list variables. He ended up "solving" the problem by copying the sublist into a new ArrayList.

The argument that you need to know how the List behaves is largely addressed by using the RandomAccess marker interface. Yes, it is a bit clunky, but the alternative is worse.

Also, how often does the situation actually require using (1) over (2) (i.e. where (2) wouldn't suffice..aside 'coding to interfaces' and best practices etc.)

The "how often" part of the question is objectively unanswerable.

(and can I please get an example)

Occasionally, the application may require that you use methods in the ArrayList API that are not in the List API. For example, ensureCapacity(int), trimToSize() or removeRange(int, int). (And the last one will only arise if you have created a subtype of ArrayList that declares the method to be public.)

That is the only sound reason for coding to the class rather than the interface, IMO.

(It is theoretically possible that you will get a slight improvement in performance ... under certain circumstances ... on some platforms ... but unless you really need that last 0.05%, it is not worth doing this. This is not a sound reason, IMO.)

You can’t write efficient code if you don’t know whether random access is efficient or not.

That is a valid point. However, Java provides better ways to deal with that; e.g.

public <T extends List & RandomAccess> void test(T list) {
    // do stuff
}

If you call that with a list that does not implement RandomAccess you will get a compilation error.

You could also test dynamically ... using instanceof ... if static typing is too awkward. And you could even write your code to use different algorithms (dynamically) depending on whether or not a list supported random access.

Note that ArrayList is not the only list class that implements RandomAccess. Others include CopyOnWriteList, Stack and Vector.

I've seen people make the same argument about Serializable (because List doesn't implement it) ... but the approach above solves this problem too. (To the extent that it is solvable at all using runtime types. An ArrayList will fail serialization if any element is not serializable.)

The argument is of length zero takes places when you get an output as an integer of length 0 and not a NULL output.i.e., integer(0).

You can further verify my point by finding the class of your output- >class(output) "integer"

I believe this is the easiest way to do it, also possible using through the inline style attribute within the <img> tag.

}

I am posting this answer so the topmost answer (when sorted by activity) is not one that is just plain wrong.

What is a Stacktrace?

A stacktrace is a very helpful debugging tool. It shows the call stack (meaning, the stack of functions that were called up to that point) at the time an uncaught exception was thrown (or the time the stacktrace was generated manually). This is very useful because it doesn't only show you where the error happened, but also how the program ended up in that place of the code. This leads over to the next question:

What is an Exception?

An Exception is what the runtime environment uses to tell you that an error occurred. Popular examples are NullPointerException, IndexOutOfBoundsException or ArithmeticException. Each of these are caused when you try to do something that is not possible. For example, a NullPointerException will be thrown when you try to dereference a Null-object:

Object a = null;
a.toString();                 //this line throws a NullPointerException

Object[] b = new Object[5];
System.out.println(b[10]);    //this line throws an IndexOutOfBoundsException,
                              //because b is only 5 elements long
int ia = 5;
int ib = 0;
ia = ia/ib;                   //this line throws an  ArithmeticException with the 
                              //message "/ by 0", because you are trying to
                              //divide by 0, which is not possible.

How should I deal with Stacktraces/Exceptions?

At first, find out what is causing the Exception. Try googleing the name of the exception to find out, what is the cause of that exception. Most of the time it will be caused by incorrect code. In the given examples above, all of the exceptions are caused by incorrect code. So for the NullPointerException example you could make sure that a is never null at that time. You could, for example, initialise a or include a check like this one:

if (a!=null) {
    a.toString();
}

This way, the offending line is not executed if a==null. Same goes for the other examples.

Sometimes you can't make sure that you don't get an exception. For example, if you are using a network connection in your program, you cannot stop the computer from loosing it's internet connection (e.g. you can't stop the user from disconnecting the computer's network connection). In this case the network library will probably throw an exception. Now you should catch the exception and handle it. This means, in the example with the network connection, you should try to reopen the connection or notify the user or something like that. Also, whenever you use catch, always catch only the exception you want to catch, do not use broad catch statements like catch (Exception e) that would catch all exceptions. This is very important, because otherwise you might accidentally catch the wrong exception and react in the wrong way.

try {
    Socket x = new Socket("1.1.1.1", 6789);
    x.getInputStream().read()
} catch (IOException e) {
    System.err.println("Connection could not be established, please try again later!")
}

Why should I not use catch (Exception e)?

Let's use a small example to show why you should not just catch all exceptions:

int mult(Integer a,Integer b) {
    try {
        int result = a/b
        return result;
    } catch (Exception e) {
        System.err.println("Error: Division by zero!");
        return 0;
    }
}

What this code is trying to do is to catch the ArithmeticException caused by a possible division by 0. But it also catches a possible NullPointerException that is thrown if a or b are null. This means, you might get a NullPointerException but you'll treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.

TLDR

1. Figure out what is the cause of the exception and fix it, so that it doesn't throw the exception at all.

2. If 1. is not possible, catch the specific exception and handle it.

   • Never just add a try/catch and then just ignore the exception! Don't do that!
   • Never use catch (Exception e), always catch specific Exceptions. That will save you a lot of headaches.

you can add the selected values in an array and set it as the value for default selection

eg:

var selectedItems =[];
selectedItems.push("your selected items");
..
$('#drp_Books_Ill_Illustrations').select2('val',selectedItems );

Try this, this should definitely work!

It really depends on where your JavaScript code is located.

The problem is probably caused by the DOM not being loaded when the line

var systemStatus = document.getElementById("system-status");

is executed. You could try calling this in an onload event, or ideally use a DOM ready type event from a JavaScript framework.

I would suggest reading some Microsoft documentation on what you can do with CSOM. This might be one example of what you are looking for, but there is a huge API documented in msdn.

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// Assume that the web has a list named "Announcements". 
List announcementsList = context.Web.Lists.GetByTitle("Announcements"); 

// Assume there is a list item with ID=1. 
ListItem listItem = announcementsList.Items.GetById(1); 

// Write a new value to the Body field of the Announcement item.
listItem["Body"] = "This is my new value!!"; 
listItem.Update(); 

context.ExecuteQuery();

no that cannot work(not with real data):

String sql = "INSERT INTO course " +
        "VALUES (course_code, course_desc, course_chair)";
    stmt.executeUpdate(sql);

change it to:

String sql = "INSERT INTO course (course_code, course_desc, course_chair)" +
        "VALUES (?, ?, ?)";

Create a PreparedStatment with that sql and insert the values with index:

PreparedStatement preparedStatement = conn.prepareStatement(sql);
preparedStatement.setString(1, "Test");
preparedStatement.setString(2, "Test2");
preparedStatement.setString(3, "Test3");
preparedStatement.executeUpdate(); 

AND is && and OR is || like in C.

1. install json-loader:

   npm i json-loader --save

2. create data folder in src:

   mkdir data

3. put your file(s) there

4. load your file

   var data = require('json!../data/yourfile.json');

Best Practice - use singular. You have a list of items that make up an Enum. Using an item in the list sounds strange when you say Versions.1_0. It makes more sense to say Version.1_0 since there is only one 1_0 Version.

std::fill(v.begin(), v.end(), 0);

You need to fill the value for Website with Facebook Login with the value http://localhost/OfferDrive/ to allow Facebook to authenticate that the requests from JavaScript SDK are coming from right place

Is there a way to have placeholders, like ? for column names? For example SELECT ? FROM TABLEA GROUP BY ?

Use dynamic query as below:

String queryString = "SELECT "+ colName+ " FROM TABLEA GROUP BY "+ colName;

If I want to simply run the above query and get a List what is the best way?

List<String> data = getJdbcTemplate().query(query, new RowMapper<String>(){
                            public String mapRow(ResultSet rs, int rowNum) 
                                                         throws SQLException {
                                    return rs.getString(1);
                            }
                       });

EDIT: To Stop SQL Injection, check for non word characters in the colName as :

          Pattern pattern = Pattern.compile("\\W");
          if(pattern.matcher(str).find()){
               //throw exception as invalid column name
          }

For your example, this will do the magic in Java 8

List<Double> testList = new ArrayList();
testList.sort(Comparator.naturalOrder());

But if you want to sort by some of the fields of the object you are sorting, you can do it easily by:

testList.sort(Comparator.comparing(ClassName::getFieldName));

or

 testList.sort(Comparator.comparing(ClassName::getFieldName).reversed());

or

 testList.stream().sorted(Comparator.comparing(ClassName::getFieldName).reversed()).collect(Collectors.toList());

Yes basically this is what virtualenv do , and this is what the activate command is for, from the doc here:

activate script

In a newly created virtualenv there will be a bin/activate shell script, or a Scripts/activate.bat batch file on Windows.

This will change your $PATH to point to the virtualenv bin/ directory. Unlike workingenv, this is all it does; it's a convenience. But if you use the complete path like /path/to/env/bin/python script.py you do not need to activate the environment first. You have to use source because it changes the environment in-place. After activating an environment you can use the function deactivate to undo the changes.

The activate script will also modify your shell prompt to indicate which environment is currently active.

so you should just use activate command which will do all that for you:

> \path\to\env\bin\activate.bat

Answer to the question

As pointed out in another answer and as you can read in PEP 3140, str on a list calls for each item __repr__. There is not much you can do about that part.

If you implement __repr__, you will get something more descriptive, but if implemented correctly, not exactly what you expected.

Proper implementation

The fast, but wrong solution is to alias __repr__ to __str__.

__repr__ should not be set to __str__ unconditionally. __repr__ should create a representation, that should look like a valid Python expression that could be used to recreate an object with the same value. In this case, this would rather be Node(2) than 2.

A proper implementation of __repr__ makes it possible to recreate the object. In this example, it should also contain the other significant members, like neighours and distance.

An incomplete example:

class Node:

    def __init__(self, id, neighbours=[], distance=0):
        self.id = id
        self.neighbours = neighbours
        self.distance = distance


    def __str__(self):
        return str(self.id)


    def __repr__(self):
        return "Node(id={0.id}, neighbours={0.neighbours!r}, distance={0.distance})".format(self)
        # in an elaborate implementation, members that have the default
        # value could be left out, but this would hide some information


uno = Node(1)    
due = Node(2)    
tri = Node(3)    
qua = Node(4)

print uno
print str(uno)
print repr(uno)

uno.neighbours.append([[due, 4], [tri, 5]])

print uno
print uno.neighbours
print repr(uno)

Note: print repr(uno) together with a proper implementation of __eq__ and __ne__ or __cmp__ would allow to recreate the object and check for equality.

It doesn't make sense to ask for the "last" key in a dictionary, because dictionary keys are unordered. You can get the list of keys and get the last one if you like, but that's not in any sense the "last key in a dictionary".

First,

1. always define certificates with CURLOPT_CAPATH option,

2. decide how your POSTed data will be transfered.

1 Certificates

By default:

• CURLOPT_SSL_VERIFYHOST == 2 which "checks the existence of a common name and also verify that it matches the hostname provided" and

• CURLOPT_VERIFYPEER == true which "verifies the peer's certificate".

So, all you have to do is:

const CAINFO = SERVER_ROOT . '/registry/cacert.pem';
...
\curl_setopt($ch, CURLOPT_CAINFO, self::CAINFO);

taken from a working class where SERVER_ROOT is a constant defined during application bootstraping like in a custom classloader, another class etc.

Forget things like \curl_setopt($handler, CURLOPT_SSL_VERIFYHOST, 0); or \curl_setopt($handler, CURLOPT_SSL_VERIFYPEER, 0);.

Find cacert.pem there as seen in this question.

2 POST modes

There are actually 2 modes when posting data:

• the data is transfered with Content-Type header set to multipart/form-data or,

• the data is a urlencoded string with application/x-www-form-urlencoded encoding.

In the first case you pass an array while in the second you pass a urlencoded string.

multipart/form-data ex.:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

application/x-www-form-urlencoded ex.:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, \http_build_query($fields));

http_build_query:

Test it at your command line as

user@group:$ php -a
php > $fields = array('a' => 'sth', 'b' => 'else');
php > echo \http_build_query($fields);
a=sth&b=else

The other end of the POST request will define the appropriate mode of connection.

Linux users can find the locations of all the installed packages like this:

pip list | xargs -exec pip show

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

Since image is deprecated, you should use varbinary.

per Microsoft (thanks for the link @Christopher)

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.

...which kind makes me thing that perhaps you could benefit from a lookup table to which you can JOIN to eliminate the CASE expression entirely.

Daniel's script appears to be a good all encompassing solution, but even he admitted that his laptop ran out of memory. Here is an option I came up with. I based my procedure off of Mohammad Nizamuddin's post on TechNet. I added an initial cursor loop that pulls all the database names into a temporary table and then uses that to pull all the base table names from each of those databases.

You can optionally pass the fill factor you would prefer and specify a target database if you do not want to re-index all databases.

--===============================================================
-- Name:  sp_RebuildAllIndexes
-- Arguements:  [Fill Factor], [Target Database name]
-- Purpose:  Loop through all the databases on a server and
--           compile a list of all the table within them.
--           This list is then used to rebuild indexes for
--           all the tables in all the database.  Optionally,
--           you may pass a specific database name if you only
--           want to reindex that target database.
--================================================================
CREATE PROCEDURE sp_RebuildAllIndexes(
    @FillFactor     INT = 90,
    @TargetDatabase NVARCHAR(100) = NULL)

    BEGIN
        DECLARE @TablesToReIndex TABLE (
            TableName VARCHAR(200)
        );
        DECLARE @DbName VARCHAR(50);
        DECLARE @TableSelect VARCHAR(MAX);
        DECLARE @DatabasesToIndex CURSOR;

        IF ISNULL( @TargetDatabase, '' ) = ''
          SET @DatabasesToIndex = CURSOR
          FOR SELECT NAME
              FROM   master..sysdatabases
        ELSE
          SET @DatabasesToIndex = CURSOR
