Solution for safe and high secured encode anyone file in OpenSSL and command-line:

You should have ready some X.509 certificate for encrypt files in PEM format.

Encrypt file:

openssl smime -encrypt -binary -aes-256-cbc -in plainfile.zip -out encrypted.zip.enc -outform DER yourSslCertificate.pem

What is what:

• smime - ssl command for S/MIME utility (smime(1))
• -encrypt - chosen method for file process
• -binary - use safe file process. Normally the input message is converted to "canonical" format as required by the S/MIME specification, this switch disable it. It is necessary for all binary files (like a images, sounds, ZIP archives).
• -aes-256-cbc - chosen cipher AES in 256 bit for encryption (strong). If not specified 40 bit RC2 is used (very weak). (Supported ciphers)
• -in plainfile.zip - input file name
• -out encrypted.zip.enc - output file name
• -outform DER - encode output file as binary. If is not specified, file is encoded by base64 and file size will be increased by 30%.
• yourSslCertificate.pem - file name of your certificate's. That should be in PEM format.

That command can very effectively a strongly encrypt big files regardless of its format.
Known issue: Something wrong happens when you try encrypt huge file (>600MB). No error thrown, but encrypted file will be corrupted. Always verify each file! (or use PGP - that has bigger support for files encryption with public key)

Decrypt file:

openssl smime -decrypt -binary -in encrypted.zip.enc -inform DER -out decrypted.zip -inkey private.key -passin pass:your_password

What is what:

• -inform DER - same as -outform above
• -inkey private.key - file name of your private key. That should be in PEM format and can be encrypted by password.
• -passin pass:your_password - your password for private key encrypt. (passphrase arguments)

EDIT: I tried using a CTE on my previous answer which was incorrect, as pointed out by @bummi. This option should work instead:

Here's one option using a CROSS APPLY, to kind of work around this problem:

SELECT st.Value, Constants.CONSTANT_ONE, Constants.CONSTANT_TWO
FROM SomeTable st
CROSS APPLY (
    SELECT 'Value1' AS CONSTANT_ONE,
           'Value2' AS CONSTANT_TWO
) Constants

I downloaded a different installer "SQL Server 2014 Express with Advanced Services" and found Instance Features in it. Thanks for Alberto Solano's answer, it was really helpful.

My first installer was "SQL Server 2014 Express". It installed only SQL Management Studio and tools without Instance features. After installation "SQL Server 2014 Express with Advanced Services" my LocalDB is now alive!!!

IIRC they suggest using the preg_ functions instead (in this case, preg_replace).

Sometimes what you're seeing is a box shadow, not a text underline.

Try this (using whatever CSS selectors are appropriate for you):

a:hover, a:visited, a:link, a:active {

    text-decoration: none!important;

    -webkit-box-shadow: none!important;
    box-shadow: none!important;
}

Yes, you may use both ways. If you just want to separate the elements and show they in separated lines, a list is simpler:

set list=A B C D

A list of values separated by space may be easily processed by for command:

(for %%a in (%list%) do (
   echo %%a
   echo/
)) > theFile.txt

You may also create an array this way:

setlocal EnableDelayedExpansion
set n=0
for %%a in (A B C D) do (
   set vector[!n!]=%%a
   set /A n+=1
)

and show the array elements this way:

(for /L %%i in (0,1,3) do (
   echo !vector[%%i]!
   echo/
)) > theFile.txt

For further details about array management in Batch files, see: Arrays, linked lists and other data structures in cmd.exe (batch) script

ATTENTION! You must know that all characters included in set command are inserted in the variable name (at left of equal sign), or in the variable value. For example, this command:

set list = "A B C D"

create a variable called list (list-space) with the value "A B C D" (space, quote, A, etc). For this reason, it is a good idea to never insert spaces in set commands. If you need to enclose the value in quotes, you must enclose both the variable name and its value:

set "list=A B C D"

PS - You should NOT use ECHO. in order to left blank lines! An alternative is ECHO/. For further details about this point, see: http://www.dostips.com/forum/viewtopic.php?f=3&t=774

Just to complement m59's correct answer, here is a working jsfiddle:

<body ng-app='myApp'>
    <div>
        <button my-directive>Click Me!</button>
    </div>
     <h1>{{2+3}}</h1>

</body>

$(".list-toggle").click(function() {
    $(this).hasAttr('colspan') ? 
        $(this).removeAttr('colspan') : $(this).attr('colspan', 6);
});

Try as follows:

public function funcname($id)
{
    $this->db->select('*');
    $this->db->from('Album a'); 
    $this->db->join('Category b', 'b.cat_id=a.cat_id', 'left');
    $this->db->join('Soundtrack c', 'c.album_id=a.album_id', 'left');
    $this->db->where('c.album_id',$id);
    $this->db->order_by('c.track_title','asc');         
    $query = $this->db->get(); 
    return $query->result_array();
}

If no result found CI returns false otherwise true

Of course the .gitignore file is showing up on the status, because it's untracked, and git sees it as a tasty new file to eat!

Since .gitignore is an untracked file however, it is a candidate to be ignored by git when you put it in .gitignore!

So, the answer is simple: just add the line:

.gitignore # Ignore the hand that feeds!

to your .gitignore file!

And, contrary to August's response, I should say that it's not that the .gitignore file should be in your repository. It just happens that it can be, which is often convenient. And it's probably true that this is the reason .gitignore was created as an alternative to .git/info/exclude, which doesn't have the option to be tracked by the repository. At any rate, how you use your .gitignore file is totally up to you.

For reference, check out the gitignore(5) manpage on kernel.org.

select top 10 p.id from(select distinct p.id  from tablename)tablename

How about this...?

TextReader tr = new StringReader("<Root>Content</Root>");
XDocument doc = XDocument.Load(tr);
Console.WriteLine(doc);

There are 3 ways of doing this:

1. By changing your 404.php code.
2. By using wordpress plugins.
3. By editing your .htaccess file.

Complete tutorial given at http://bornvirtual.com/wordpress/redirect-404-error-in-wordpress/906/

For the following HTML document:

<html>
  <body>
    <a href="http://www.example.com">Example</a> 
    <a href="http://www.stackoverflow.com">SO</a> 
  </body>
</html>

The xpath query /html/body//a/@href (or simply //a/@href) will return:

    http://www.example.com
    http://www.stackoverflow.com

To select a specific instance use /html/body//a[N]/@href,

    $ /html/body//a[2]/@href
    http://www.stackoverflow.com

To test for strings contained in the attribute and return the attribute itself place the check on the tag not on the attribute:

    $ /html/body//a[contains(@href,'example')]/@href
    http://www.example.com

Mixing the two:

    $ /html/body//a[contains(@href,'com')][2]/@href
    http://www.stackoverflow.com

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

Array instantiation performance

If you wish to create an array with no length:

var arr = []; is faster than var arr = new Array();

If you wish to create an empty array with a certain length:

var arr = new Array(x); is faster than var arr = []; arr[x-1] = undefined;

For benchmarks click the following: https://jsfiddle.net/basickarl/ktbbry5b/

I do not however know the memory footprint of both, I can imagine that new Array() takes up more space.

So, I had this code:

<div class="dropdown-select-wrapper" *ngIf="contentData">
    <button mat-stroked-button [disableRipple]="true" class="mat-button" (click)="openSelect()" [ngClass]="{'only-icon': !contentData?.buttonText?.length}">
      <i *ngIf="contentData.iconClassInfo" class="dropdown-icon {{contentData.iconClassInfo.name}}"></i>
      <span class="button-text" *ngIf="contentData.buttonText">{{contentData.buttonText}}</span>
    </button>
    <mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();">
      <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
        {{option[contentData.optionsStructure.keyName]}}
      </mat-option>
    </mat-select>
  </div>

Here I was using standalone formControl, and I was getting the error we are talking about, which made no sense for me, since I wasn't working with formgroups or formarrays... it only disappeared when I added the *ngIf to the select it self, so is not being used before it actually exists. That's what solved the issue in my case.

<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();" *ngIf="theFormControl">
          <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
            {{option[contentData.optionsStructure.keyName]}}
          </mat-option>
        </mat-select>

Use either of the two commands below. Everything must be in uppercase. The table name must be wrapped in quotation marks:

--SEE THE CONSTRAINTS ON A TABLE
SELECT COLUMN_NAME, CONSTRAINT_NAME FROM USER_CONS_COLUMNS WHERE TABLE_NAME = 'TBL_CUSTOMER';

--OR FOR LESS DETAIL
SELECT CONSTRAINT_NAME FROM USER_CONSTRAINTS WHERE TABLE_NAME = 'TBL_CUSTOMER';

Yes, StringBuilder gives better performance while performing repeated operation over a string. It is because all the changes are made to a single instance so it can save a lot of time instead of creating a new instance like String.

String Vs Stringbuilder

• String

  1. under System namespace
  2. immutable (read-only) instance
  3. performance degrades when continuous change of value occures
  4. thread safe

• StringBuilder (mutable string)

  1. under System.Text namespace
  2. mutable instance
  3. shows better performance since new changes are made to existing instance

Strongly recommend dotnet mob article : String Vs StringBuilder in C#.

Related Stack Overflow question: Mutability of string when string doesn't change in C#?.

Well I can see two solutions here:

1) Follow the Docs-Tkinter install for Python (for Windows):

Tkinter (and, since Python 3.1, ttk) are included with all standard Python distributions. It is important that you use a version of Python supporting Tk 8.5 or greater, and ttk. We recommend installing the "ActivePython" distribution from ActiveState, which includes everything you'll need.

In your web browser, go to Activestate.com, and follow along the links to download the Community Edition of ActivePython for Windows. Make sure you're downloading a 3.1 or newer version, not a 2.x version.

Run the installer, and follow along. You'll end up with a fresh install of ActivePython, located in, e.g. C:\python32. From a Windows command prompt, or the Start Menu's "Run..." command, you should then be able to run a Python shell via:

% C:\python32\python

This should give you the Python command prompt. From the prompt, enter these two commands:

>>> import tkinter
>>> tkinter._test()

This should pop up a small window; the first line at the top of the window should say "This is Tcl/Tk version 8.5"; make sure it is not 8.4!

2) Uninstall 64-bit Python and install 32 bit Python.

I have experienced this exact problem and found, on the users machine, one of the libraries I depended on was marked as "MISSING" in the references dialog. In that case it was some office font library that was available in my version of Office 2007, but not on the client desktop.

The error you get is a complete red herring (as pointed out by divo).

Fortunately I wasn't using anything from the library, so I was able to remove it from the XLA references entirely. I guess, an extension of divo' suggested best practice would be for testing to check the XLA on all the target Office versions (not a bad idea in any case).

I used code that was published on CodeProject.com. If you want to use POP3, it is one of the better solutions that I have found.

Using description as many of these answers suggest is the wrong approach - even if you get it to work, it will break in iOS 13+.

Instead you should ensure you use the actual binary data, not simply a description of it. Andrey Gagan addressed the Objective C solution quite well, but fortunately it's much simpler in swift:

Swift 4.2 works in iOS 13+

// credit to NSHipster (see link above)
// format specifier produces a zero-padded, 2-digit hexadecimal representation
let deviceTokenString = deviceToken.map { String(format: "%02x", $0) }.joined()

First, Set :
ALTER TABLE person ALTER COLUMN phone DROP NOT NULL;

As shown in this example, you can apply a background to a canvas element through CSS and this background will not be considered part the image, e.g. when fetching the contents through toDataURL().

Here are the contents of the example, for Stack Overflow posterity:

<!DOCTYPE HTML>
<html><head>
  <meta charset="utf-8">
  <title>Canvas Background through CSS</title>
  <style type="text/css" media="screen">
    canvas, img { display:block; margin:1em auto; border:1px solid black; }
    canvas { background:url(lotsalasers.jpg) }
  </style>
</head><body>
<canvas width="800" height="300"></canvas>
<img>
<script type="text/javascript" charset="utf-8">
  var can = document.getElementsByTagName('canvas')[0];
  var ctx = can.getContext('2d');
  ctx.strokeStyle = '#f00';
  ctx.lineWidth   = 6;
  ctx.lineJoin    = 'round';
  ctx.strokeRect(140,60,40,40);
  var img = document.getElementsByTagName('img')[0];
  img.src = can.toDataURL();
</script>
</body></html>

Can place code anywhere

<input class="my_<? print 'test' ?>"  />

The only way to have multiple, separately accessible functions in a single file is to define STATIC METHODS using object-oriented programming. You'd access the function as myClass.static1(), myClass.static2() etc.

OOP functionality is only officially supported since R2008a, so unless you want to use the old, undocumented OOP syntax, the answer for you is no, as explained by @gnovice.

EDIT

One more way to define multiple functions inside a file that are accessible from the outside is to create a function that returns multiple function handles. In other words, you'd call your defining function as [fun1,fun2,fun3]=defineMyFunctions, after which you could use out1=fun1(inputs) etc.

I take it you're not on a Mac. Use insert key.

That's not possible with CSS, you will have to use the Javascript for that. Although you can set the width of the p to as much as 30 characters and next letters will automatically come down but again this won't be that accurate and will vary if the characters are in capital.

This should be a comment, but comments don't allow multi-line code.

Here's what's happening:

in Event.cpp

#include "Event.h"

preprocessor starts processing Event.h

#ifndef EVENT_H_

it isn't defined yet, so keep going

#define EVENT_H_
#include "common.h"

common.h gets processed ok

#include "Item.h"

Item.h gets processed ok

#include "Flight.h"

Flight.h gets processed ok

#include "Landing.h"

preprocessor starts processing Landing.h

#ifndef LANDING_H_

not defined yet, keep going

#define LANDING_H_

#include "Event.h"

preprocessor starts processing Event.h

#ifndef EVENT_H_

This IS defined already, the whole rest of the file gets skipped. Continuing with Landing.h

class Landing: public Event {

The preprocessor doesn't care about this, but the compiler goes "WTH is Event? I haven't heard about Event yet."

This is a simplified variation of Fernando's answer. This is for Linux and either Python 2 or 3. No external library is needed, and no external process is run.

import glob

def get_command_pid(command):
    for path in glob.glob('/proc/*/comm'):
        if open(path).read().rstrip() == command:
            return path.split('/')[2]

Only the first matching process found will be returned, which works well for some purposes. To get the PIDs of multiple matching processes, you could just replace the return with yield, and then get a list with pids = list(get_command_pid(command)).

Alternatively, as a single expression:

For one process:

next(path.split('/')[2] for path in glob.glob('/proc/*/comm') if open(path).read().rstrip() == command)

For multiple processes:

[path.split('/')[2] for path in glob.glob('/proc/*/comm') if open(path).read().rstrip() == command]

Dim fileEntries As String() = Directory.GetFiles("YourPath", "*.txt")
' Process the list of .txt files found in the directory. '
Dim fileName As String

For Each fileName In fileEntries
    If (System.IO.File.Exists(fileName)) Then
        'Read File and Print Result if its true
        ReadFile(fileName)
    End If
    TransfereFile(fileName, 1)
Next

This is expected behavior for an uncaught exception with display_errors off.

Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.

 ini_set("display_errors", 1);

or

 try{
     // code that may throw an exception
 } catch(Exception $e){
     echo $e->getMessage();
 }

If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).

Another option for you would be to use set_exception_handler to set a default error handler for your script.

 function default_exception_handler(Exception $e){
          // show something to the user letting them know we fell down
          echo "<h2>Something Bad Happened</h2>";
          echo "<p>We fill find the person responsible and have them shot</p>";
          // do some logging for the exception and call the kill_programmer function.
 }
 set_exception_handler("default_exception_handler");

try it, maybe useful...

box-shadow: 0 0 0 3px rgb(255,255,255), 0 7px 3px #cbc9c9;
                    -webkit-box-shadow: 0 0 0 3px rgb(255,255,255), 0 7px 5px #cbc9c9;
                    -o-box-shadow: 0 0 0 3px rgb(255,255,255), 0 7px 5px #cbc9c9;
                    -moz-box-shadow: 0 0 0 3px rgb(255,255,255), 0 7px 5px #cbc9c9;  

above CSS cause you have a box shadow in bottom.
you can red more Here

Okay, so you've got two options here :

1. Use jQuery UI's accordion - its nice, easy and fast. See more info here
2. Or, if you still wanna do this by yourself, you could remove the fieldset (its not semantically right to use it for this anyway) and create a structure by yourself.

Here's how you do that. Create a HTML structure like this :

<div class="container">
    <div class="header"><span>Expand</span>

    </div>
    <div class="content">
        <ul>
            <li>This is just some random content.</li>
            <li>This is just some random content.</li>
            <li>This is just some random content.</li>
            <li>This is just some random content.</li>
        </ul>
    </div>
</div>

With this CSS: (This is to hide the .content stuff when the page loads.

.container .content {
    display: none;
    padding : 5px;
}

Then, using jQuery, write a click event for the header.

$(".header").click(function () {

    $header = $(this);
    //getting the next element
    $content = $header.next();
    //open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
        //change text of header based on visibility of content div
        $header.text(function () {
            //change text based on condition
            return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });

});

Here's a demo : http://jsfiddle.net/hungerpain/eK8X5/7/

SVN seems to handle binary deltas more efficiently than Git.

I had to decide on a versioning system for documentation (JPEG files, PDF files, and .odt files). I just tested adding a JPEG file and rotating it 90 degrees four times (to check effectiveness of binary deltas). Git's repository grew 400%. SVN's repository grew by only 11%.

So it looks like SVN is much more efficient with binary files.

So my choice is Git for source code and SVN for binary files like documentation.

See the github help on cloning URL. With HTTPS, if you are not authorized to push, you would basically have a read-only access. So yes, you need to ask the author to give you permission.

If the author doesn't give you permission, you can always fork (clone) his repository and work on your own. Once you made a nice and tested feature, you can then send a pull request to the original author.

In their book The Practice of Programming (which is well worth reading), Kernighan and Pike discuss this problem, and they solve it by using snprintf() to create the string with the correct buffer size for passing to the scanf() family of functions. In effect:

int scanner(const char *data, char *buffer, size_t buflen)
{
    char format[32];
    if (buflen == 0)
        return 0;
    snprintf(format, sizeof(format), "%%%ds", (int)(buflen-1));
    return sscanf(data, format, buffer);
}

Note, this still limits the input to the size provided as 'buffer'. If you need more space, then you have to do memory allocation, or use a non-standard library function that does the memory allocation for you.

Note that the POSIX 2008 (2013) version of the scanf() family of functions supports a format modifier m (an assignment-allocation character) for string inputs (%s, %c, %[). Instead of taking a char * argument, it takes a char ** argument, and it allocates the necessary space for the value it reads:

char *buffer = 0;
if (sscanf(data, "%ms", &buffer) == 1)
{
    printf("String is: <<%s>>\n", buffer);
    free(buffer);
}

If the sscanf() function fails to satisfy all the conversion specifications, then all the memory it allocated for %ms-like conversions is freed before the function returns.

A very important place where it is REQUIRED to use the key => value pair in foreach loop is to be mentioned. Suppose you would want to add a new/sub-element to an existing item (in another key) in the $features array. You should do the following:

foreach($features as $key => $feature) {
    $features[$key]['new_key'] = 'new value';  
} 

Instead of this:

foreach($features as $feature) {
    $feature['new_key'] = 'new value';  
} 

The big difference here is that, in the first case you are accessing the array's sub-value via the main array itself with a key to the element which is currently being pointed to by the array pointer.

While in the second (which doesn't work for this purpose) you are assigning the sub-value in the array to a temporary variable $feature which is unset after each loop iteration.

[2,3,5].filter(i => ![5].includes(i))

As soon as question is about dynamic array you may want not just to create array with variable size, but also to change it's size during runtime. Here is an example with memcpy, you can use memcpy_s or std::copy as well. Depending on compiler, <memory.h> or <string.h> may be required. When using this functions you allocate new memory region, copy values of original memory regions to it and then release them.

//    create desired array dynamically
size_t length;
length = 100; //for example
int *array = new int[length];

//   now let's change is's size - e.g. add 50 new elements
size_t added = 50;
int *added_array = new int[added];

/*   
somehow set values to given arrays
*/ 

//    add elements to array
int* temp = new int[length + added];
memcpy(temp, array, length * sizeof(int));
memcpy(temp + length, added_array, added * sizeof(int));
delete[] array;
array = temp;

You may use constant 4 instead of sizeof(int).

Also you are trying to set value2 using Set keyword, which is not required. You can directly use rng.value2 = 1

below test code for ref.

Sub test()
    Dim rng As Range
    Set rng = Range("A1")
    rng.Value2 = 1
End Sub

Maybe you can wrap the PowerShell invocation in a .bat file like so:

rem ps.bat
@echo off
powershell.exe -command "%*"

If you then placed this file under a folder in your PATH, you could call PowerShell scripts like this:

ps foo 1 2 3

Quoting can get a little messy, though:

Now you can use https://sites.google.com

Build internal project hubs, team sites, public-facing websites, and more—all without designer, programmer, or IT help. With the new Google Sites, building websites is easy. Just drag content where you need it.

You can use LIKE statement instead of =. But to do this with DateStamp you need to CONVERT it first to VARCHAR:

SELECT * 
FROM [User] U
WHERE CONVERT(VARCHAR, U.DateCreated, 120) LIKE '2014-02-07%'

If you do not increase the height of navbar..

mine was strange... IntelliJ specific quirk.

I looked at my output classes and there was a folder:

x.y.z

instead of

x/y/z

but if you have certain options set in IntelliJ, in the navigator they will both look like x.y.z

so check your output folder if you're scratching your head

System.currentTimeMillis() does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date instance to a string before using it. You can use DateFormats to convert Dates to Strings in any timezone:

DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());

Also see this related question.

Html.Raw() returns IHtmlString, not the ordinary string. So, you cannot write them in opposite sides of : operator. Remove that .ToString() calling

@{int count = 0;}
@foreach (var item in Model.Resources)
{
    @(count <= 3 ? Html.Raw("<div class=\"resource-row\">"): Html.Raw("")) 
    // some code
    @(count <= 3 ? Html.Raw("</div>") : Html.Raw("")) 
    @(count++)

}

By the way, returning IHtmlString is the way MVC recognizes html content and does not encode it. Even if it hasn't caused compiler errors, calling ToString() would destroy meaning of Html.Raw()

The reason I used a + instead of a '*' is because a plus is defined as one or more of the preceding element, where an asterisk is zero or more. In this case we want a delimiter that's a little more concrete, so "one or more" spaces.

word[Aa]\s+word[Bb]\s+word[Cc]

will match:

wordA wordB     wordC
worda wordb wordc
wordA   wordb   wordC

The words, in this expression, will have to be specific, and also in order (a, b, then c)

You have two options:

Either use:

sb.setLength(0);  // It will just discard the previous data, which will be garbage collected later.  

Or use:

sb.delete(0, sb.length());  // A bit slower as it is used to delete sub sequence.  

NOTE

Avoid declaring StringBuffer or StringBuilder objects within the loop else it will create new objects with each iteration. Creating of objects requires system resources, space and also takes time. So for long run, avoid declaring them within a loop if possible.

Use ast.literal_eval to evaluate Python literals. However, what you have is JSON (note "true" for example), so use a JSON deserializer.

>>> import json
>>> s = """{"id":"123456789","name":"John Doe","first_name":"John","last_name":"Doe","link":"http:\/\/www.facebook.com\/jdoe","gender":"male","email":"jdoe\u0040gmail.com","timezone":-7,"locale":"en_US","verified":true,"updated_time":"2011-01-12T02:43:35+0000"}"""
>>> json.loads(s)
{u'first_name': u'John', u'last_name': u'Doe', u'verified': True, u'name': u'John Doe', u'locale': u'en_US', u'gender': u'male', u'email': u'[email protected]', u'link': u'http://www.facebook.com/jdoe', u'timezone': -7, u'updated_time': u'2011-01-12T02:43:35+0000', u'id': u'123456789'}

The IntelliJ debugger has a very handy feature called "Evaluate Expression", that is by far better than eclipses pendant. It has full code-completion and i concider it to be generally "more useful".

Here is a random alpha numeric generator

print left(replace(newid(),'-',''),@length) //--@length is the length of random Num.

argv and argc are how command line arguments are passed to main() in C and C++.

argc will be the number of strings pointed to by argv. This will (in practice) be 1 plus the number of arguments, as virtually all implementations will prepend the name of the program to the array.

The variables are named argc (argument count) and argv (argument vector) by convention, but they can be given any valid identifier: int main(int num_args, char** arg_strings) is equally valid.

They can also be omitted entirely, yielding int main(), if you do not intend to process command line arguments.

Try the following program:

#include <iostream>

int main(int argc, char** argv) {
    std::cout << "Have " << argc << " arguments:" << std::endl;
    for (int i = 0; i < argc; ++i) {
        std::cout << argv[i] << std::endl;
    }
}

Running it with ./test a1 b2 c3 will output

Have 4 arguments:
./test
a1
b2
c3

I don't think it's a matter of being Pythonic or elegant. It's a matter of preventing exceptions as much as you can. Exceptions are meant to handle errors that might occur in code or events you have no control over.

In this case, you have full control when checking if an item is an attribute or in a dictionary, so avoid nested exceptions and stick with your second attempt.

I have read all the answers above, and some directed me to the problem, but not to the solution for the problem.

The root cause of the problem is disableSelection(). It is causing all the problems, but removing it is not a solution, as (at least in 2016 or slightly before), on touch-screen devices, you "have" to use this if you want to be able to move objects with jQuery.

The solution was to leave the disableSelection() to the sortable element, but also add a binding action just above:

 $('#your_selector_id form').bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(event) {
    event.stopImmediatePropagation();
 })

The form in the jQuery element is just to stop propagation on the form, as you might need propagation on some elements.

I read all replies in this thread and some referred also to this thread: Remove empty dicts in nested dictionary with recursive function

I originally used solution here and it worked great:

Attempt 1: Too Hot (not performant or future-proof):

def scrub_dict(d):
    if type(d) is dict:
        return dict((k, scrub_dict(v)) for k, v in d.iteritems() if v and scrub_dict(v))
    else:
        return d

But some performance and compatibility concerns were raised in Python 2.7 world:

1. use isinstance instead of type
2. unroll the list comp into for loop for efficiency
3. use python3 safe items instead of iteritems

Attempt 2: Too Cold (Lacks Memoization):

def scrub_dict(d):
    new_dict = {}
    for k, v in d.items():
        if isinstance(v,dict):
            v = scrub_dict(v)
        if not v in (u'', None, {}):
            new_dict[k] = v
    return new_dict

DOH! This is not recursive and not at all memoizant.

Attempt 3: Just Right (so far):

def scrub_dict(d):
    new_dict = {}
    for k, v in d.items():
        if isinstance(v,dict):
            v = scrub_dict(v)
        if not v in (u'', None, {}):
            new_dict[k] = v
    return new_dict

You need to return a view which has a friendly error message to the user

catch (Exception ex)
{
   // to do :log error
   return View("Error");
}

You should not be showing the internal details of your exception(like exception stacktrace etc) to the user. You should be logging the relevant information to your error log so that you can go through it and fix the issue.

If your request is an ajax request, You may return a JSON response with a proper status flag which client can evaluate and do further actions

[HttpPost]
public ActionResult Create(CustomerVM model)
{
  try
  {
   //save customer
    return Json(new { status="success",message="customer created"});
  }
  catch(Exception ex)
  {
    //to do: log error
   return Json(new { status="error",message="error creating customer"});
  }
} 

If you want to show the error in the form user submitted, You may use ModelState.AddModelError method along with the Html helper methods like Html.ValidationSummary etc to show the error to the user in the form he submitted.

Take a look at Traverse. It will recursively walk an object tree for you and at every node you have a number of different objects you can access - key of current node, value of current node, parent of current node, full key path of current node, etc. https://github.com/substack/js-traverse. I've used it to good effect on objects that I wanted to scrub circular references to and when I need to do a deep clone while transforming various data bits. Here's some code pulled form their samples to give you a flavor of what it can do.

var id = 54;
var callbacks = {};
var obj = { moo : function () {}, foo : [2,3,4, function () {}] };

var scrubbed = traverse(obj).map(function (x) {
    if (typeof x === 'function') {
        callbacks[id] = { id : id, f : x, path : this.path };
        this.update('[Function]');
        id++;
    }
});

console.dir(scrubbed);
console.dir(callbacks);

I think it is implemented in the engine as Matthias said: WHERE, GROUP BY, HAVING

I found the tutorial Working with UIGestureRecognizers, and I think that is what I am looking for. It helped me come up with the following solution:

-(IBAction) someMethod {
    UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)];
    [panRecognizer setMinimumNumberOfTouches:1];
    [panRecognizer setMaximumNumberOfTouches:1];
    [ViewMain addGestureRecognizer:panRecognizer];
    [panRecognizer release];
}

-(void)move:(UIPanGestureRecognizer*)sender {
    [self.view bringSubviewToFront:sender.view];
    CGPoint translatedPoint = [sender translationInView:sender.view.superview];

    if (sender.state == UIGestureRecognizerStateBegan) {
        firstX = sender.view.center.x;
        firstY = sender.view.center.y;
    }


    translatedPoint = CGPointMake(sender.view.center.x+translatedPoint.x, sender.view.center.y+translatedPoint.y);

    [sender.view setCenter:translatedPoint];
    [sender setTranslation:CGPointZero inView:sender.view];

    if (sender.state == UIGestureRecognizerStateEnded) {
        CGFloat velocityX = (0.2*[sender velocityInView:self.view].x);
        CGFloat velocityY = (0.2*[sender velocityInView:self.view].y);

        CGFloat finalX = translatedPoint.x + velocityX;
        CGFloat finalY = translatedPoint.y + velocityY;// translatedPoint.y + (.35*[(UIPanGestureRecognizer*)sender velocityInView:self.view].y);

        if (finalX < 0) {
            finalX = 0;
        } else if (finalX > self.view.frame.size.width) {
            finalX = self.view.frame.size.width;
        }

        if (finalY < 50) { // to avoid status bar
            finalY = 50;
        } else if (finalY > self.view.frame.size.height) {
            finalY = self.view.frame.size.height;
        }

        CGFloat animationDuration = (ABS(velocityX)*.0002)+.2;

        NSLog(@"the duration is: %f", animationDuration);

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:animationDuration];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDidStopSelector:@selector(animationDidFinish)];
        [[sender view] setCenter:CGPointMake(finalX, finalY)];
        [UIView commitAnimations];
    }
}

There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:

function get-loggedonuser ($computername){

#mjolinor 3/17/10

$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'

$logontype = @{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}

$logon_sessions = @(gwmi win32_logonsession -ComputerName $computername)
$logon_users = @(gwmi win32_loggedonuser -ComputerName $computername)

$session_user = @{}

$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}


$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)

$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime

$loggedonuser
}

}

This answer is for SO users who browse here after searching for the error.

• Terminal will not accept your Bitbucket or Atlassian web app password if
  your account is associated with an Atlassian (Jira) account. If this is your case, you have a giant string generated for you that you can find in your MacOSX keychain app. This is the password Terminal accepts.
• It is not clear how to re-generate this password or re-set it to match what Bitbucket will accept.
• Changing password in SourceTree's settings did not work for me.
• Changing password in Atlassian account profile did not work for me.
• Bitbucket does not have a link or interface to change password for this case in the Bitbucket account profile - user has to go to Atlassian account profile.

In my case, nothing worked because I changed my username in Bitbucket.

Atlassian and Bitbucket are not completely integrated. Bitbucket uses the Atlassian user email and web app password, but allows you to have a different username.

There seems to be a bug in this process, especially since it's not clear which application or process is generating the authentication and where it's stored or editable. Changing the username breaks authentication.

There may be a way to update the username used by the credentials and Bitbucket, but I was already several hours behind when I discovered that changing my username back to what it was before restored authentication.

It sounds like you are almost definitely behind a proxy server.

Where this does not work for me behind my proxy:

svn checkout http://v8.googlecode.com/svn/trunk/ v8-read-only

this does:

svn --config-option servers:global:http-proxy-host=MY_PROXY_HOST --config-option servers:global:http-proxy-port=MY_PROXY_PORT checkout http://v8.googlecode.com/svn/trunk/ v8-read-only

UPDATE I forgot to quote my source :-)

This will not only change the max_retries but also enable a backoff strategy which makes requests to all http:// addresses sleep for a period of time before retrying (to a total of 5 times):

import requests
from urllib3.util.retry import Retry
from requests.adapters import HTTPAdapter

s = requests.Session()

retries = Retry(total=5,
                backoff_factor=0.1,
                status_forcelist=[ 500, 502, 503, 504 ])

s.mount('http://', HTTPAdapter(max_retries=retries))

s.get('http://httpstat.us/500')

As per documentation for Retry: if the backoff_factor is 0.1, then sleep() will sleep for [0.1s, 0.2s, 0.4s, ...] between retries. It will also force a retry if the status code returned is 500, 502, 503 or 504.

Various other options to Retry allow for more granular control:

• total – Total number of retries to allow.
• connect – How many connection-related errors to retry on.
• read – How many times to retry on read errors.
• redirect – How many redirects to perform.
• method_whitelist – Set of uppercased HTTP method verbs that we should retry on.
• status_forcelist – A set of HTTP status codes that we should force a retry on.
• backoff_factor – A backoff factor to apply between attempts.
• raise_on_redirect – Whether, if the number of redirects is exhausted, to raise a MaxRetryError, or to return a response with a response code in the 3xx range.
• raise_on_status – Similar meaning to raise_on_redirect: whether we should raise an exception, or return a response, if status falls in status_forcelist range and retries have been exhausted.

NB: raise_on_status is relatively new, and has not made it into a release of urllib3 or requests yet. The raise_on_status keyword argument appears to have made it into the standard library at most in python version 3.6.

To make requests retry on specific HTTP status codes, use status_forcelist. For example, status_forcelist=[503] will retry on status code 503 (service unavailable).

By default, the retry only fires for these conditions:

• Could not get a connection from the pool.
• TimeoutError
• HTTPException raised (from http.client in Python 3 else httplib). This seems to be low-level HTTP exceptions, like URL or protocol not formed correctly.
• SocketError
• ProtocolError

Notice that these are all exceptions that prevent a regular HTTP response from being received. If any regular response is generated, no retry is done. Without using the status_forcelist, even a response with status 500 will not be retried.

To make it behave in a manner which is more intuitive for working with a remote API or web server, I would use the above code snippet, which forces retries on statuses 500, 502, 503 and 504, all of which are not uncommon on the web and (possibly) recoverable given a big enough backoff period.

EDITED: Import Retry class directly from urllib3.

Okay, looks like big solutions.

Why not to add width: 100%; directly in your iframe. ;)

So your code would looks something like <iframe style="width: 100%;" ...></iframe>

Try this it'll work as it worked in my case.

Enjoy! :)

You are looking for the update method

dic0.update( dic1 )
print( dic0 ) 

gives

{'dic0': 0, 'dic1': 1}

>>> source_list = ('1','a'),('2','b'),('3','c'),('4','d')
>>> list1, list2 = zip(*source_list)
>>> list1
('1', '2', '3', '4')
>>> list2
('a', 'b', 'c', 'd')

Edit: Note that zip(*iterable) is its own inverse:

>>> list(source_list) == zip(*zip(*source_list))
True

When unpacking into two lists, this becomes:

>>> list1, list2 = zip(*source_list)
>>> list(source_list) == zip(list1, list2)
True

Addition suggested by rocksportrocker.

It's because the in.nextInt() doesn't change line. So you first "enter" (after you press 3 ) cause the endOfLine read by your in.nextLine() in your loop.

Here a small change that you can do:

int nnames;
    String names[];

    System.out.print("How many names are you going to save: ");
    Scanner in = new Scanner(System.in);
    nnames = Integer.parseInt(in.nextLine());
    names = new String[nnames];

    for (int i = 0; i < names.length; i++){
            System.out.print("Type a name: ");
            names[i] = in.nextLine();
    }

Below is the easy one -

cat countvariable.sh

echo "$@" |awk '{for(i=0;i<=NF;i++); print i-1 }'

Output :

#./countvariable.sh 1 2 3 4 5 6
6
#./countvariable.sh 1 2 3 4 5 6 apple orange
8

IF d was created by Newtonsoft you can use this to read property names and values:

    foreach (JProperty property in d)
    {
        DoSomething(property.Name, property.Value);
    }

JDBC uses a so-called "connection URL", so you can escape "+" by "%2B", that is

useTimezone=true&serverTimezone=GMT%2B8

I noticed that Eemuli said that you can't change the log level after they are created - and while that might be the design, it isn't entirely true.

I ran into a situation where I was using a library that logged to slf4j - and I was using the library while writing a maven mojo plugin.

Maven uses a (hacked) version of the slf4j SimpleLogger, and I was unable to get my plugin code to reroute its logging to something like log4j, which I could control.

And I can't change the maven logging config.

So, to quiet down some noisy info messages, I found I could use reflection like this, to futz with the SimpleLogger at runtime.

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.spi.LocationAwareLogger;
    try
    {
        Logger l = LoggerFactory.getLogger("full.classname.of.noisy.logger");  //This is actually a MavenSimpleLogger, but due to various classloader issues, can't work with the directly.
        Field f = l.getClass().getSuperclass().getDeclaredField("currentLogLevel");
        f.setAccessible(true);
        f.set(l, LocationAwareLogger.WARN_INT);
    }
    catch (Exception e)
    {
        getLog().warn("Failed to reset the log level of " + loggerName + ", it will continue being noisy.", e);
    }

Of course, note, this isn't a very stable / reliable solution... as it will break the next time the maven folks change their logger.

You should do

alert(data[0].name); //Take the property name of the first array

and not

 alert(data.myName)

jQuery should be able to sniff the dataType for you even if you don't set it so no need for JSON.parse.

According to the documentation, use a relative path for a local jar dependency as follows:

}

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

#include <iostream>

using namespace std;

string getWord(istream& in) 
{
    int c;

    string word;

    // TODO: remove whitespace from begining of stream ?

    while( !in.eof() ) 
    {

        c = in.get();

        if( c == ' ' || c == '\t' || c == '\n' ) break;

        word += c;
    }

    return word;
}

int main()
{
    string word;

    do {

        word = getWord(cin);

        cout << "[" << word << "]";

    } while( word != "#");

    return 0;
}

What you are possibly looking for is map(). You can "convert" the objects in a stream to another by mapping this way:

...
 .map(userMeal -> new UserMealExceed(...))
...

Well one of the option is to goto your workspace, your project folder, then bin copy and paste the log4j properites file. it would be better to paste the file also in source folder.

Now you may want to know from where to get this file, download smslib, then extract it, then smslib->misc->log4j sample configuration -> log4j here you go.

This what helped,me so just wanted to know.

You can also use pytiff of which I'm the author.

    import pytiff

    with pytiff.Tiff("filename.tif") as handle:
        part = handle[100:200, 200:400]

    # multipage tif
    with pytiff.Tiff("multipage.tif") as handle:
        for page in handle:
            part = page[100:200, 200:400]

It's a fairly small module and may not have as many features as other modules, but it supports tiled tiffs and bigtiff, so you can read parts of large images.

If you're using Visual Studio 2015 and you're encountering this problem, you can install MS Office Developer Tools for VS2015 here.

Alternative using the Stream API:

list.stream().reduce((first, second) -> second)

Results in an Optional of the last element.

and take a look at this http://requirejs.org/docs/api.html

Use Cython to convert to C, compile, and link with GCC.

Another could be, make the core functions in C (the ones you want to make hard to reverse), compile them and use Boost.Python to import the compiled code (plus you get a much faster code execution). Then use any tool mentioned to distribute.

Let's say for instance you want to get a list of all your customers:

var customers = context.Customers.ToList();

And let's assume that each Customer object has a reference to its set of Orders, and that each Order has references to LineItems which may also reference a Product.

As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include() allows you to indicate which related entities should be read from the database as part of the same query.

Using the same example, this might bring in all of the related order headers, but none of the other records:

var customersWithOrderDetail = context.Customers.Include("Orders").ToList();

As a final point since you asked for SQL, the first statement without Include() could generate a simple statement:

SELECT * FROM Customers;

The final statement which calls Include("Orders") may look like this:

SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;

This is also known as the "inline if", or as above the ternary operator. https://en.wikipedia.org/wiki/%3F:

It's used to reduce code, though it's not recommended to use a lot of these on a single line as it may make maintaining code quite difficult. Imagine:

a = b?c:(d?e:(f?g:h));

and you could go on a while.

It ends up basically the same as writing:

if(b)
  a = c;
else if(d)
  a = e;
else if(f)
  a = g;
else
  a = h;

In your case, "string requestUri = _apiURL + "?e=" + OperationURL[0] + ((OperationURL[1] == "GET") ? GetRequestSignature() : "");"

Can also be written as: (omitting the else, since it's an empty string)

string requestUri = _apiURL + "?e=" + OperationURL[0];
if((OperationURL[1] == "GET")
    requestUri = requestUri + GetRequestSignature();

or like this:

string requestUri;
if((OperationURL[1] == "GET")
    requestUri = _apiURL + "?e=" + OperationURL[0] + GetRequestSignature();
else
    requestUri = _apiURL + "?e=" + OperationURL[0];

Depending on your preference / the code style your boss tells you to use.

this is useful in the builder pattern.

public class User {

    private String firstName;
    private String surname;

    public User(Builder builder){
        firstName = builder.firstName;
        surname = builder.surname;
    }

    public String getFirstName(){
        return firstName;
    }

    public String getSurname(){
        return surname;
    }

    public static class Builder {
        private String firstName;
        private String surname;

        public Builder setFirstName(String firstName) {
            this.firstName = firstName;
            return this;
        }

        public Builder setSurname(String surname) {
            this.surname = surname;
            return this;
        }

        public User build(){
            return new User(this);
        }

    }

    public static void main(String[] args) {
        User.Builder builder = new User.Builder();
        User user = builder.setFirstName("John").setSurname("Doe").build();
    }

}

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.

Usage is simple.

string directoryPath = Path.GetDirectoryName(filePath);

This script will convert, to UTF-8 without BOM, all .txt files in DIRECTORY1 and output them to DIRECTORY2

foreach ($i in ls -name DIRECTORY1\*.txt)
{
    $file_content = Get-Content "DIRECTORY1\$i";
    [System.IO.File]::WriteAllLines("DIRECTORY2\$i", $file_content);
}

In order to sync multiple models along with custom pivot data, you need this:

$user->roles()->sync([ 
    1 => ['expires' => true],
    2 => ['expires' => false],
    ...
]);

Ie.

sync([
    related_id => ['pivot_field' => value],
    ...
]);

edit

Answering the comment:

$speakers  = (array) Input::get('speakers'); // related ids
$pivotData = array_fill(0, count($speakers), ['is_speaker' => true]);
$syncData  = array_combine($speakers, $pivotData);

$user->roles()->sync($syncData);

select * from Table ORDER BY id LIMIT 30

Notes: * id should be unique. * You can control the numbers of rows returned by replacing the 30 in the query

I have gone through this question earlier but did not found complete gui based solution.Today I got a GUI based solution provided by spring.

In short we need to do only that much:

1.Install plugin in eclipse from update site: site link

2.Import project as gradle and browse the .gradle file..that's it.

Complete documentation is here

I'm afraid there is no "better" way to get this size, however it's not that much pain.

Of course your code should be safe for both binary/mono images as well as multi-channel ones, but the principal dimensions of the image always come first in the numpy array's shape. If you opt for readability, or don't want to bother typing this, you can wrap it up in a function, and give it a name you like, e.g. cv_size:

import numpy as np
import cv2

# ...

def cv_size(img):
    return tuple(img.shape[1::-1])

If you're on a terminal / ipython, you can also express it with a lambda:

>>> cv_size = lambda img: tuple(img.shape[1::-1])
>>> cv_size(img)
(640, 480)

Writing functions with def is not fun while working interactively.

Edit

Originally I thought that using [:2] was OK, but the numpy shape is (height, width[, depth]), and we need (width, height), as e.g. cv2.resize expects, so - we must use [1::-1]. Even less memorable than [:2]. And who remembers reverse slicing anyway?

file() is not supported in Python 3

Use open() instead; see Built-in Functions - open().

Supposing you use sql server:

WHERE StartTime BETWEEN DATEADD(HOUR, -1, GetDate())
                    AND DATEADD(HOUR, 1, GetDate())

This is my nginx config file and iosocket code. Server(express) is listening on port 9191. It works well: nginx config file:

server {
    listen       443 ssl;
    server_name  localhost;
    root   /usr/share/nginx/html/rdist;

    location /user/ {
        proxy_pass   http://localhost:9191;
    }
    location /api/ {
        proxy_pass   http://localhost:9191;
    }
    location /auth/ {
        proxy_pass   http://localhost:9191;
    }

    location / {
        index  index.html index.htm;
        if (!-e $request_filename){
          rewrite ^(.*)$ /index.html break;
        }
    }
    location /socket.io/ {
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass   http://localhost:9191/socket.io/;
    }


    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    ssl_certificate /etc/nginx/conf.d/sslcert/xxx.pem;
    ssl_certificate_key /etc/nginx/conf.d/sslcert/xxx.key;

}

Server:

const server = require('http').Server(app)
const io = require('socket.io')(server)
io.on('connection', (socket) => {
    handleUserConnect(socket)

  socket.on("disconnect", () => {
   handleUserDisConnect(socket)
  });
})

server.listen(9191, function () {
  console.log('Server listening on port 9191')
})

Client(react):

    const socket = io.connect('', { secure: true, query: `userId=${this.props.user._id}` })

        socket.on('notifications', data => {
            console.log('Get messages from back end:', data)
            this.props.mergeNotifications(data)
        })

As answered in other posts, you have two different options for different platforms. What I do is:

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady() {

    // Mock device.platform property if not available
    if (!window.device) {
        window.device = { platform: 'Browser' };
    }

    handleExternalURLs();
}

function handleExternalURLs() {
    // Handle click events for all external URLs
    if (device.platform.toUpperCase() === 'ANDROID') {
        $(document).on('click', 'a[href^="http"]', function (e) {
            var url = $(this).attr('href');
            navigator.app.loadUrl(url, { openExternal: true });
            e.preventDefault();
        });
    }
    else if (device.platform.toUpperCase() === 'IOS') {
        $(document).on('click', 'a[href^="http"]', function (e) {
            var url = $(this).attr('href');
            window.open(url, '_system');
            e.preventDefault();
        });
    }
    else {
        // Leave standard behaviour
    }
}

So as you can see I am checking the device platform and depending on that I am using a different method. In case of a standard browser, I leave standard behaviour. From now on the solution will work fine on Android, iOS and in a browser, while HTML page won't be changed, so that it can have URLs represented as standard anchor

The solution requires InAppBrowser and Device plugins

At first I wondered why the OP hadn't already marked one of the responses as the answer, but after trying it myself and still have it not work, I dug a little deeper and found there's much more to this issue then I'd first supposed.

A better understanding can be gained by reading from a similar question: Why won't control update/refresh mid-process

Lastly, for the record, I was able to get my label to update by doing the following:

private void SetStatus(string status) 
{
    lblStatus.Text = status;
    lblStatus.Invalidate();
    lblStatus.Update();
    lblStatus.Refresh();
    Application.DoEvents();
}

Though from what I understand this is far from an elegant and correct approach to doing it. It's a hack that may or may not work depending upon how busy the thread is.

The issue you're encountering is that even though the method emptyList() returns List<T>, you haven't provided it with the type, so it defaults to returning List<Object>. You can supply the type parameter, and have your code behave as expected, like this:

public Person(String name) {
  this(name,Collections.<String>emptyList());
}

Now when you're doing straight assignment, the compiler can figure out the generic type parameters for you. It's called type inference. For example, if you did this:

public Person(String name) {
  List<String> emptyList = Collections.emptyList();
  this(name, emptyList);
}

then the emptyList() call would correctly return a List<String>.

This will surely help on bootstrap timepicker

format :"DD:MM:YYYY HH:mm"

SELECT column1 FROM table WHERE column1 not like '%[0-9]%'

Removing the '^' did it for me. I'm looking at a varchar field and when I included the ^ it excluded all of my non-numerics which is exactly what I didn't want. So, by removing ^ I only got non-numeric values back.

It depends on whether you are submitting the form normally or via an AJAX call. You can find lots of information at jquery.com, including documentation with examples. For submitting a form normally, check out the submit() method to at that site. For AJAX, there are many different possibilities, though you probably want to use either the ajax() or post() methods. Note that post() is really just a convenient way to call the ajax() method with a simplified, and limited, interface.

A critical resource, one I use every day, that you should bookmark is How jQuery Works. It has tutorials on using jQuery and the left-hand navigation gives access to all of the documentation.

Examples:

Normal

$('form#myForm').submit();

AJAX

$('input#submitButton').click( function() {
    $.post( 'some-url', $('form#myForm').serialize(), function(data) {
         // ... do something with response from server
       },
       'json' // I expect a JSON response
    );
});

$('input#submitButton').click( function() {
    $.ajax({
        url: 'some-url',
        type: 'post',
        dataType: 'json',
        data: $('form#myForm').serialize(),
        success: function(data) {
                   // ... do something with the data...
                 }
    });
});

Note that the ajax() and post() methods above are equivalent. There are additional parameters you can add to the ajax() request to handle errors, etc.

findAny & orElse

By using findAny() and orElse():

Person matchingObject = objects.stream().
filter(p -> p.email().equals("testemail")).
findAny().orElse(null);

Stops looking after finding an occurrence.

findAny

Optional<T> findAny()

Returns an Optional describing some element of the stream, or an empty Optional if the stream is empty. This is a short-circuiting terminal operation. The behavior of this operation is explicitly nondeterministic; it is free to select any element in the stream. This is to allow for maximal performance in parallel operations; the cost is that multiple invocations on the same source may not return the same result. (If a stable result is desired, use findFirst() instead.)

if you are using IIS, maybe you should try
"application pools" --> "DefaultAppPool" --> "application pools default value" --> "32-Bit-application-activ" --> set false

well, I know this is pretty old but I think that what you might need is:

var one = someObservable.take(1);

var two = someOtherObservable.pipe(
  concatMap((twoRes) => one.pipe(mapTo(twoRes))),
  take(1)
).subscribe((twoRes) => {
   // one is completed and we get two's subscription.
})

In JavaScript, most functions are both callable and instantiable: they have both a [[Call]] and [[Construct]] internal methods.

As callable objects, you can use parentheses to call them, optionally passing some arguments. As a result of the call, the function can return a value.

var player = makeGamePlayer("John Smith", 15, 3);

The code above calls function makeGamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function makeGamePlayer(name, totalScore, gamesPlayed) {
  // Define desired object
  var obj = {
    name:  name,
    totalScore: totalScore,
    gamesPlayed: gamesPlayed
  };
  // Return it
  return obj;
}

Additionally, when you call a function you are also passing an additional argument under the hood, which determines the value of this inside the function. In the case above, since makeGamePlayer is not called as a method, the this value will be the global object in sloppy mode, or undefined in strict mode.

As constructors, you can use the new operator to instantiate them. This operator uses the [[Construct]] internal method (only available in constructors), which does something like this:

1. Creates a new object which inherits from the .prototype of the constructor
2. Calls the constructor passing this object as the this value
3. It returns the value returned by the constructor if it's an object, or the object created at step 1 otherwise.

var player = new GamePlayer("John Smith", 15, 3);

The code above creates an instance of GamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function GamePlayer(name,totalScore,gamesPlayed) {
  // `this` is the instance which is currently being created
  this.name =  name;
  this.totalScore = totalScore;
  this.gamesPlayed = gamesPlayed;
  // No need to return, but you can use `return this;` if you want
}

By convention, constructor names begin with an uppercase letter.

The advantage of using constructors is that the instances inherit from GamePlayer.prototype. Then, you can define properties there and make them available in all instances

You can template a struct as well as a class. However you can't template a typedef. So template<typename T> struct array {...}; works, but template<typename T> typedef struct {...} array; does not. Note that there is no need for the typedef trick in C++ (you can use structs without the struct modifier just fine in C++).

You can set events on a combination of key and mouse events, and onblur as well, to be sure. In that event, store the value of the input. In the next call, compare the current value with the lastly stored value. Only do your magic if it has actually changed.

To do this in a more or less clean way:

You can associate data with a DOM element (lookup api.jquery.com/jQuery.data ) So you can write a generic set of event handlers that are assigned to all elements in the form. Each event can pass the element it was triggered by to one generic function. That one function can add the old value to the data of the element. That way, you should be able to implement this as a generic piece of code that works on your whole form and every form you'll write from now on. :) And it will probably take no more than about 20 lines of code, I guess.

An example is in this fiddle: http://jsfiddle.net/zeEwX/

Whatever algebra you are doing in Excel to create the new column could probably be done more effectively in R.

Please try the following: Read the raw file (before any excel manipulation) into R using read.csv(... stringsAsFactors=FALSE). [If that does not work, please take a look at ?read.table (which read.csv wraps), however there may be some other underlying issue].

For example:

   delim = ","  # or is it "\t" ?
   dec = "."    # or is it "," ?
   myDataFrame <- read.csv("path/to/file.csv", header=TRUE, sep=delim, dec=dec, stringsAsFactors=FALSE)

Then, let's say your numeric columns is column 4

   myDataFrame[, 4]  <- as.numeric(myDataFrame[, 4])  # you can also refer to the column by "itsName"

You can grant permissions on a view and not the base table. This is one of the reasons people like using views.

Have a look here: GRANT Object Permissions (Transact-SQL)

While the instructions on the Boost web site are helpful, here is a condensed version that also builds x64 libraries.

• You only need to do this if you are using one of the libraries mentioned in section 3 of the instructions page. (E.g., to use Boost.Filesystem requires compilation.) If you are not using any of those, just unzip and go.

Build the 32-bit libraries

This installs the Boost header files under C:\Boost\include\boost-(version), and the 32-bit libraries under C:\Boost\lib\i386. Note that the default location for the libraries is C:\Boost\lib but you’ll want to put them under an i386 directory if you plan to build for multiple architectures.

1. Unzip Boost into a new directory.
2. Start a 32-bit MSVC command prompt and change to the directory where Boost was unzipped.
3. Run: bootstrap

4. Run: b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\i386 install

   • For Visual Studio 2012, use toolset=msvc-11.0
   • For Visual Studio 2010, use toolset=msvc-10.0
   • For Visual Studio 2017, use toolset=msvc-14.1

5. Add C:\Boost\include\boost-(version) to your include path.

6. Add C:\Boost\lib\i386 to your libs path.

Build the 64-bit libraries

This installs the Boost header files under C:\Boost\include\boost-(version), and the 64-bit libraries under C:\Boost\lib\x64. Note that the default location for the libraries is C:\Boost\lib but you’ll want to put them under an x64 directory if you plan to build for multiple architectures.

1. Unzip Boost into a new directory.
2. Start a 64-bit MSVC command prompt and change to the directory where Boost was unzipped.
3. Run: bootstrap
4. Run: b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\x64 architecture=x86 address-model=64 install
   • For Visual Studio 2012, use toolset=msvc-11.0
   • For Visual Studio 2010, use toolset=msvc-10.0
5. Add C:\Boost\include\boost-(version) to your include path.
6. Add C:\Boost\lib\x64 to your libs path.

SOLUTION

As stated by others very well, HTTP_REFERER is set by the local machine of the user, specifically the browser, which means it's not reliable for security. However, this still is entirely the way in which Google Analytics monitors where you're getting your visitors from, so, it can actually be useful to check, exclude, include, etc..

If you think you should see an HTTP_REFERER and do not, add this to your PHP code, preferably at the top:

ini_set('session.referer_check', 'TRUE');

A more appropriate long-term solution, of course, is to actually update your php.ini or equivalent file. This is a nice and quick way of verifying, though.

TESTING

Run print($_SERVER['HTTP_REFERER']); on your site, go to google.com, inspect some text, edit it to be <a href="https://example.com">LINK!</a>, apply the change, then click the link. If it works, all is well and running precisely!

But maybe $_SERVER is wrong, or the test above says it's broken. Update your page with this, and then test again...

<script type="text/javascript">
    console.log("REFER!" + document.referrer + "|" + location.referrer + "|");
</script>

USES

I use HTTP REFERER to block spam sites in GoogleAnalytics. Below is a graph focusing on one particular website's referrals. From 0 to 44 in one day, it wasn't caused by real users. It was caused by a botted site trying to get my attention to buy their services. But it just started because php.ini was updated to ignore the referer, which meant these spam, junk garbage sites were not getting their appropriate ERROR 403, "Access Denied."

Using the pairwise itertools recipe:

import itertools
def pairwise(iterable):
    "s -> (s0,s1), (s1,s2), (s2, s3), ..."
    a, b = itertools.tee(iterable)
    next(b, None)
    return itertools.izip(a, b)

def pair_averages(seq):
    return ( (a+b)/2 for a, b in pairwise(seq) )

you can try

"str".charCodeAt(0)

Sass is a CSS pre-processor with syntax advancements. Style sheets in the advanced syntax are processed by the program, and turned into regular CSS style sheets. However, they do not extend the CSS standard itself.

CSS variables are supported and can be utilized but not as well as pre-processor variables.

For the difference between SCSS and Sass, this text on the Sass documentation page should answer the question:

There are two syntaxes available for Sass. The first, known as SCSS (Sassy CSS) and used throughout this reference, is an extension of the syntax of CSS. This means that every valid CSS stylesheet is a valid SCSS file with the same meaning. This syntax is enhanced with the Sass features described below. Files using this syntax have the .scss extension.

The second and older syntax, known as the indented syntax (or sometimes just “Sass”), provides a more concise way of writing CSS. It uses indentation rather than brackets to indicate nesting of selectors, and newlines rather than semicolons to separate properties. Files using this syntax have the .sass extension.

However, all this works only with the Sass pre-compiler which in the end creates CSS. It is not an extension to the CSS standard itself.

for ( i = 0; i < total.length; i++ );
                                    ^-- remove the semi-colon here

With this semi-colon, the loop loops until i == total.length, doing nothing, and then what you thought was the body of the loop is executed.

I was working with Jupyter-Notebook when I encountered this deceptive error.

I wasn't able to resolve through the solutions provided above as I neither had a detached head nor did I have different names for my local and remote repo.

But what I did have was my file sizes were slightly greater than 1MB and the largest was almost ~2MB.

I reduced the file size of each of the file using https://stackoverflow.com/questions/37807308/[][1] technique.

It helped reduce my file size by clearing the outputs. I was able to push the code, henceforth as it brought my file size in KBs.

Index is actually available like;

_.sortBy([1, 4, 2, 66, 444, 9], function(num, index){  });

I made the following code so that even beginners can understand. Just copy the code and read comments. Note that message to be send is declared as a global variable which you can change just before sending the message. General changes can be done in Handler function.

If you are using graphLab, you can use this function. It is really powerfull

products['word_count'] = graphlab.text_analytics.count_words(your_text)

For Android Studio 3.5, fount it using instructions here: https://developer.android.com/studio/debug/device-file-explorer (View -> Tool Windows -> Device File Explorer -> -> databases

You get this error when declaring a forward reference inside the wrong namespace thus declaring a new type without defining it. For example:

namespace X
{
  namespace Y
  {
    class A;

    void func(A* a) { ... } // incomplete type here!
  }
}

...but, in class A was defined like this:

namespace X
{
  class A { ... };
}

Thus, A was defined as X::A, but I was using it as X::Y::A.

The fix obviously is to move the forward reference to its proper place like so:

namespace X
{
  class A;
  namespace Y
  {
    void func(X::A* a) { ... } // Now accurately referencing the class`enter code here`
  }
}

Often the order of the processing does not matter. GNU Parallel is made for this situation:

grep xyz abc.txt | parallel echo do stuff to {}

If you processing is more like:

grep xyz abc.txt | myprogram_reading_from_stdin

and myprogram is slow then you can run:

grep xyz abc.txt | parallel --pipe myprogram_reading_from_stdin

You can use this function in your application to add keys to indexed array.

public static function convertIndexedArrayToAssociative($indexedArr, $keys)
{
    $resArr = array();
    foreach ($indexedArr as $item)
    {
        $tmpArr = array();
        foreach ($item as $key=>$value)
        {
            $tmpArr[$keys[$key]] = $value;
        }
        $resArr[] = $tmpArr;
    }
    return $resArr;
}

Suppose you have a suite with 10 tests. 8 of the tests share the same setup/teardown code. The other 2 don't.

setup and teardown give you a nice way to refactor those 8 tests. Now what do you do with the other 2 tests? You'd move them to another testcase/suite. So using setup and teardown also helps give a natural way to break the tests into cases/suites

make sure your properties file exist in classpath directory but not in sub folder of your classpath directory. if it is exist in sub folder then write as below classpath:subfolder/idm.properties

You can do with Very Simple Step

$(':radio[id=radio1]').change(function() {
   $("#yes").removeClass("none");
   $("#no").addClass("none");


});
$(':radio[id=radio2]').change(function() {
   $("#no").removeClass("none");
   $("#yes").addClass("none");

});

The code below demonstrates 3 different ways of doing it:

• virtual function
• typeid
• dynamic_cast

#include <iostream>
#include <typeinfo>
#include <typeindex>

enum class Type {Base, A, B};

class Base {
public:
    virtual ~Base() = default;
    virtual Type type() const {
        return Type::Base;
    }
};

class A : public Base {
    Type type() const override {
        return Type::A;
    }
};

class B : public Base {
    Type type() const override {
        return Type::B;
    }
};

int main()
{
    const char *typemsg;
    A a;
    B b;
    Base *base = &a;             // = &b;    !!!!!!!!!!!!!!!!!
    Base &bbb = *base;

    // below you can replace    base    with  &bbb    and get the same results

    // USING virtual function
    // ======================
    // classes need to be in your control
    switch(base->type()) {
    case Type::A:
        typemsg = "type A";
        break;
    case Type::B:
        typemsg = "type B";
        break;
    default:
        typemsg = "unknown";
    }
    std::cout << typemsg << std::endl;

    // USING typeid
    // ======================
    // needs RTTI. under gcc, avoid -fno-rtti
    std::type_index ti(typeid(*base));
    if (ti == std::type_index(typeid(A))) {
        typemsg = "type A";
    } else if (ti == std::type_index(typeid(B))) {
        typemsg = "type B";
    } else {
        typemsg = "unknown";
    }
    std::cout << typemsg << std::endl;

    // USING dynamic_cast
    // ======================
    // needs RTTI. under gcc, avoid -fno-rtti
    if (dynamic_cast</*const*/ A*>(base)) {
        typemsg = "type A";
    } else if (dynamic_cast</*const*/ B*>(base)) {
        typemsg = "type B";
    } else {
        typemsg = "unknown";
    }
    std::cout << typemsg << std::endl;
}

The program above prints this:

type A
type A
type A

It's simple .First you should clear your collection and after clear list like this code :

 yourCollection.clear();
 setListAdapter(null);

you can simple use this following code

train_data['labels']= train_data[["LABEL1","LABEL1","LABEL2","LABEL3","LABEL4","LABEL5","LABEL6","LABEL7"]].values.tolist()
train_df = pd.DataFrame(train_data, columns=['text','labels'])

On Android, I tried using @diyism answer but I encountered the space character issue raised by @rpetrich, for example: I fill out a form where username = "us+us" and password = "pw pw" causing a URL string to look like:

http://somewhere?username=us%2Bus&password=pw+pw

However, @diyism code returns "us+us" and "pw+pw", i.e. it doesn't detect the space character. If the URL was rewritten with %20 the space character gets identified:

http://somewhere?username=us%2Bus&password=pw%20pw

This leads to the following fix:

Uri uri = Uri.parse(url_string.replace("+", "%20"));
uri.getQueryParameter("para1");

Get rid of the position:relative; and replace it with float:left; and float:right;.

Example in jsfiddle: http://jsfiddle.net/d9fHP/1/

        <html>
<title>
Website Title </title>
<div id="the whole thing" style="float:left; height:100%; width:100%">
    <div id="leftThing" style="float:left; width:25%; background-color:blue;">
         Left Side Menu
    </div>
    <div id="content" style="float:left; width:50%; background-color:green;">
         Random Content
    </div>
    <div id="rightThing" style="float:right; width:25%; background-color:yellow;">
         Right Side Menu
    </div>
</div>
</html>?

With versions of cut I know of, no, this is not possible. cut is primarily useful for parsing files where the separator is not whitespace (for example /etc/passwd) and that have a fixed number of fields. Two separators in a row mean an empty field, and that goes for whitespace too.

Another suggestion is to use imagesLoaded plugin.

$("img").imagesLoaded(function(){
alert( $(this).width() );
alert( $(this).height() );
});

Steps to get this error ;

1. Clone a repo (for eg take name as xyz)in a folder
2. Not try to clone again in the same folder . Even after deleting the folder manually this error will come since deleting folder doesn't delete git info .

Solution : rm -rf "name of repo folder which in out case is xyz" . So

rm -rf xyz

In a ColdFusion environment, one thing that will cause an error, even with well-formed JSON, is having Enable Request Debugging Output turned on in the ColdFusion Administrator (under Debugging & Logging > Debug Output Settings). Debugging information will be returned with the JSON data and will thus make it invalid.

[+]is simpler

    String s = "ddjdjdj+kfkfkf";

    if(s.contains ("+"))
    {
        String parts[] = s.split("[+]");
        s =  parts[0]; // i want to strip part after  +
    }
    System.out.println(s);

This works for me.

@Test
public void cloneTest() {
    List<Part> parts = new ArrayList<Part>();
    Part part1 = new Part(1);
    parts.add(part1);
    Part part2 = new Part(2);
    parts.add(part2);
    try {
        ObjectMapper objectMapper = new ObjectMapper();
        String jsonStr = objectMapper.writeValueAsString(parts);

        List<Part> cloneParts = objectMapper.readValue(jsonStr, new TypeReference<ArrayList<Part>>() {});
    } catch (Exception e) {
        //fail("failed.");
        e.printStackTrace();
    }

    //TODO: Assert: compare both list values.
}

You can use .indexOf() and .substr() like this:

var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)

You can test it out here. If you're sure of the format and there's only one question mark, you can just do this:

var myString = $("input").val().split("?").pop();

For me this error was due to the command prompt, which was not running under administrator privileges. You need to right click on the command prompt and say "Run as administrator".

You need administrator role to install or uninstall a service.

You can accomplish this with pure CSS and complete browser support, both for vertically-long and horizontally-long images at the same time.

Here's a snippet which works in Chrome, Firefox, and Safari (both using object-fit: scale-down, and without using it):

If for whatever reason you'd like to catch the output of Console.WriteLine, you CAN do this:

protected void Application_Start(object sender, EventArgs e)
{
    var writer = new LogWriter();
    Console.SetOut(writer);
}

public class LogWriter : TextWriter
{
    public override void WriteLine(string value)
    {
        //do whatever with value
    }

    public override Encoding Encoding
    {
        get { return Encoding.Default; }
    }
}

I know this post is a bit old, but thought I would add the functions I use that take into account any filters and any <![CDATA[some stuff]]> content you want to safely exclude.

Simply add to your functions.php file and use anywhere you would like, such as:

content(53);

or

excerpt(27);

Enjoy!

//limit excerpt
function excerpt($limit) {
  $excerpt = explode(' ', get_the_excerpt(), $limit);
  if (count($excerpt)>=$limit) {
    array_pop($excerpt);
    $excerpt = implode(" ",$excerpt).'...';
  } else {
    $excerpt = implode(" ",$excerpt);
  } 
  $excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt);
  return $excerpt;
}

//limit content 
function content($limit) {
  $content = explode(' ', get_the_content(), $limit);
  if (count($content)>=$limit) {
    array_pop($content);
    $content = implode(" ",$content).'...';
  } else {
    $content = implode(" ",$content);
  } 
  $content = preg_replace('/\[.+\]/','', $content);
  $content = apply_filters('the_content', $content); 
  $content = str_replace(']]>', ']]>', $content);
  return $content;
}

Dynamic resources can only be used when property being set is on object which is derived from dependency object or freezable where as static resources can be used anywhere. You can abstract away entire control using static resources.

Static resources are used under following circumstances:

1. When reaction resource changes at runtime is not required.
2. If you need a good performance with lots of resources.
3. While referencing resources within the same dictionary.

Dynamic resources:

1. Value of property or style setter theme is not known until runtime
   • This include system, aplication, theme based settings
   • This also includes forward references.
2. Referencing large resources that may not load when page, windows, usercontrol loads.
3. Referencing theme styles in a custom control.

One additional hint. Place the '-P' option after the scp command, no matter whether the machine you are ssh-ing into is the second one (aka destination). Example:

scp -P 2222 /absolute_path/source-folder/some-file [email protected]:/absolute_path/destination-folder

For the second part of your question, you can also use shift, for example:

df['t-1'] = df['t'].shift(1)

t-1 would then contain the values from t one row above.

I have a case scenario and I tried all the answers from above, but always new image was created on top of the old one. The solution that worked for me is:

imageView.setImageResource(R.drawable.image);

Suppose your project has the following structure and you want to do imports in the notebook.ipynb:

/app
  /mypackage
    mymodule.py
  /notebooks
    notebook.ipynb

If you are running Jupyter inside a docker container without any virtualenv it might be useful to create Jupyter (ipython) config in your project folder:

/app
  /profile_default
    ipython_config.py

Content of ipython_config.py:

c.InteractiveShellApp.exec_lines = [
    'import sys; sys.path.append("/app")'

Open the notebook and check it out:

print(sys.path)

['', '/usr/local/lib/python36.zip', '/usr/local/lib/python3.6', '/usr/local/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages/IPython/extensions', '/root/.ipython', '/app']

Now you can do imports in your notebook without any sys.path appending in the cells:

from mypackage.mymodule import myfunc

DateTime.Now.ToShortTimeString().ToString()

This Will give you DateTime as 10:50PM

Here's how I successfully upgraded from v0.8.18 to v0.10.20 without any other requirements like brew etc, (type these commands in the terminal):

1. sudo npm cache clean -f (force) clear you npm cache
2. sudo npm install -g n install n (this might take a while)
3. sudo n stable upgrade to the current stable version

Note that sudo might prompt your password.

Additional note regarding step 3: stable can be exchanged for latest, lts (long term support) or any specific version number such as 0.10.20.

If the version number doesn't show up when typing node -v, you might have to reboot.

These instructions are found here as well: davidwalsh.name/upgrade-nodejs
More info about the n package found here: npmjs.com/package/n
More info about Node.js' release schedule: github.com/nodejs/Release

I got the same problem also. Here's what I did:

If you're already done granting the user/group the rights to use the profile name.

1. Go to the configuration Wizard of Database Mail
2. Tick Manage profile security
3. On public profiles tab, check your profile name
4. On private profiles tab, select NT AUTHORITY\NETWORK SERVICE for user name and check your profile name
5. Do #4 this time for NT AUTHORITY\SYSTEM user name
6. Click Next until Finish.

string input = "OneTwoThree";
(if input.length >5)
{
string str=input.substring(input.length-5,5);
}

Numeric primitives in class scope are initialized to zero when not explicitly initialized.

Numeric primitives in local scope (variables in methods) must be explicitly initialized.

If you are only worried about division by zero exceptions, checking that your double is not exactly zero works great.

if(value != 0)
    //divide by value is safe when value is not exactly zero.

Otherwise when checking if a floating point value like double or float is 0, an error threshold is used to detect if the value is near 0, but not quite 0.

public boolean isZero(double value, double threshold){
    return value >= -threshold && value <= threshold;
}

Or you can use relative units, e.g.

#thing {
    position: absolute;
    width: 50vw;
    right: 25vw;
}

You can access the data-type of a column with dtype:

for y in agg.columns:
    if(agg[y].dtype == np.float64 or agg[y].dtype == np.int64):
          treat_numeric(agg[y])
    else:
          treat_str(agg[y])

1. Open your favorite text editor
2. Create a new file named whatever.h
3. Put your function prototypes in it

DONE.

Example whatever.h

#ifndef WHATEVER_H_INCLUDED
#define WHATEVER_H_INCLUDED
int f(int a);
#endif

Note: include guards (preprocessor commands) added thanks to luke. They avoid including the same header file twice in the same compilation. Another possibility (also mentioned on the comments) is to add #pragma once but it is not guaranteed to be supported on every compiler.

Example whatever.c

#include "whatever.h"

int f(int a) { return a + 1; }

And then you can include "whatever.h" into any other .c file, and link it with whatever.c's object file.

Like this:

sample.c

#include "whatever.h"

int main(int argc, char **argv)
{
    printf("%d\n", f(2)); /* prints 3 */
    return 0;
}

To compile it (if you use GCC):

$ gcc -c whatever.c -o whatever.o
$ gcc -c sample.c -o sample.o

To link the files to create an executable file:

$ gcc sample.o whatever.o -o sample

You can test sample:

$ ./sample

$

Diff command in Unix is used to find the differences between files(all types). Since directory is also a type of file, the differences between two directories can easily be figure out by using diff commands. For more option use man diff on your unix box.

 -b              Ignores trailing blanks  (spaces  and  tabs)
                 and   treats  other  strings  of  blanks  as
                 equivalent.

 -i              Ignores the case of  letters.  For  example,
                 `A' will compare equal to `a'.
 -t              Expands <TAB> characters  in  output  lines.
                 Normal or -c output adds character(s) to the
                 front of each line that may adversely affect
                 the indentation of the original source lines
                 and  make  the  output  lines  difficult  to
                 interpret.  This  option  will  preserve the
                 original source's indentation.

 -w              Ignores all blanks (<SPACE> and <TAB>  char-
                 acters)  and  treats  all  other  strings of
                 blanks   as   equivalent.    For    example,
                 `if ( a == b )'   will   compare   equal  to
                 `if(a==b)'.

and there are many more.

Edit: Although this question has been marked as a duplicate, it has still been getting attention. The answer provided by @JaKXz is correct and should be the accepted answer.

You'll need to check for the existence of the view. Then do a CREATE VIEW or ALTER VIEW depending on the result.

IF OBJECT_ID('dbo.data_VVVV') IS NULL
BEGIN
    CREATE VIEW dbo.data_VVVV
    AS
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
END
ELSE
    ALTER VIEW dbo.data_VVVV
    AS
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
BEGIN
END

Simple INNER JOIN VIEW code....

CREATE VIEW room_view
AS SELECT a.*,b.*
FROM j4_booking a INNER JOIN j4_scheduling b
on a.room_id = b.room_id;

If using getline is an option - Not neglecting its security issues and if you wish to brace pointers - you can avoid string functions as the getline returns the number of characters. Something like below

#include <stdio.h>
#include <stdlib.h>
int main()
{
    char *fname, *lname;
    size_t size = 32, nchar; // Max size of strings and number of characters read
    fname = malloc(size * sizeof *fname);
    lname = malloc(size * sizeof *lname);
    if (NULL == fname || NULL == lname)
    {
        printf("Error in memory allocation.");
        exit(1);
    }
    printf("Enter first name ");
    nchar = getline(&fname, &size, stdin);
    if (nchar == -1) // getline return -1 on failure to read a line.
    {
        printf("Line couldn't be read..");
        // This if block could be repeated for next getline too
        exit(1);
    }
    printf("Number of characters read :%zu\n", nchar);
    fname[nchar - 1] = '\0';
    printf("Enter last name ");
    nchar = getline(&lname, &size, stdin);
    printf("Number of characters read :%zu\n", nchar);
    lname[nchar - 1] = '\0';
    printf("Name entered %s %s\n", fname, lname);
    return 0;
}

^{Note: The [ security issues ] with getline shouldn't be neglected though.}

a simple img-element is not very flexible so i combined it with a picture-element. this way no CSS is needed. when an error occurs, all srcset's are set to the fallback version. a broken link image is not showing up. it does not load unneeded image versions. the picture-element supports responsive design and multiple fallbacks for types that are not supported by the browser.

<picture>
    <source id="s1" srcset="image1_not_supported_by_browser.webp" type="image/webp">
    <source id="s2" srcset="image2_broken_link.png" type="image/png">
    <img src="image3_fallback.jpg" alt="" onerror="this.onerror=null;document.getElementById('s1').srcset=document.getElementById('s2').srcset=this.src;">
</picture>

Please set this in root vc:

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];
    self.navigationController.interactivePopGestureRecognizer.enabled = NO;

}

-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:YES];
    self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}

If you like to manually manage your profiles (mostly to clean up):

• Open Windows/Devices in Xcode 6
• Select your device
• Show Provisioning Profiles:
• 
• You'll get + and - buttons to add/remove profiles:
• 

No longer supported ... you can also download Apple's iPhone Configuration Utility 3.5 for Mac OS X, it still has "Provisioning Profiles" and works with Xcode 5 -- it's now gone from Apples site but you can find an alternative download link in @suda's comment.

yes, we can declare an abstract class without any abstract method. the purpose of declaring a class as abstract is not to instantiate the class.

so two cases

1) abstract class with abstract methods.

these type of classes, we must inherit a class from this abstract class and must override the abstract methods in our class, ex: GenricServlet class

2) abstract class without abstract methods.

these type of classes, we must inherit a class from this abstract class, ex: HttpServlet class purpose of doing is although you if you don't implement your logic in child class you can get the parent logic

please check the HttpServlet source code

Create a .c file containing just the line:

_MSC_VER

or

CompilerVersion=_MSC_VER

then pre-process with

cl /nologo /EP <filename>.c

It is easy to parse the output.

you can use $.param to assign data :

 $http({
  url: "http://example.appspot.com/rest/app",
  method: "POST",
  data: $.param({"foo":"bar"})
  }).success(function(data, status, headers, config) {
   $scope.data = data;
  }).error(function(data, status, headers, config) {
   $scope.status = status;
 });

look at this : AngularJS + ASP.NET Web API Cross-Domain Issue

You can do it even without the HTTP_PROXY environment variable. Try this sample:

import urllib2

proxy_support = urllib2.ProxyHandler({"http":"http://61.233.25.166:80"})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)

html = urllib2.urlopen("http://www.google.com").read()
print html

In your case it really seems that the proxy server is refusing the connection.

Something more to try:

import urllib2

#proxy = "61.233.25.166:80"
proxy = "YOUR_PROXY_GOES_HERE"

proxies = {"http":"http://%s" % proxy}
url = "http://www.google.com/search?q=test"
headers={'User-agent' : 'Mozilla/5.0'}

proxy_support = urllib2.ProxyHandler(proxies)
opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler(debuglevel=1))
urllib2.install_opener(opener)

req = urllib2.Request(url, None, headers)
html = urllib2.urlopen(req).read()
print html

Edit 2014: This seems to be a popular question / answer. However today I would use third party requests module instead.

For one request just do:

import requests

r = requests.get("http://www.google.com", 
                 proxies={"http": "http://61.233.25.166:80"})
print(r.text)

For multiple requests use Session object so you do not have to add proxies parameter in all your requests:

import requests

s = requests.Session()
s.proxies = {"http": "http://61.233.25.166:80"}

r = s.get("http://www.google.com")
print(r.text)

1. We need Git Bash
2. In Git Bash Command Section::

1.1 ls

It will show you default location.

1.2 CD "C:\Users\user\Desktop\HTML" We need to assign project path

1.3 git init It will initialize the empty git repository in C:\Users\user\Desktop\HTML

1.4 ls It will list all files name

1.5 git remote add origin https://github.com/repository/test.git it is your https://github.com/repository/test.git is your repository path

1.6 git remote -v To check weather we have fetch or push permisson or not

1.7 git add . If you put . then it mean whatever we have in perticular folder publish all.

1.8 git commit -m "First time"

1.9 git push -u origin master

  public List<int> ConvertStringListToIntList(List<string> list) 
  {
     List<int> resultList = new List<int>();
     for (int i = 0; i < list.Count; i++)
        resultList.Add(Convert.ToInt32(list[i]));

     return resultList;
  }

I'm guessing you don't have a jquery form plugin included. ajaxSubmit isn't a core jquery function, I believe.

Something like this : http://jquery.malsup.com/form/

UPD

<script src="http://malsup.github.com/jquery.form.js"></script> 

Use this :

public View getViewByPosition(int pos, ListView listView) {
    final int firstListItemPosition = listView.getFirstVisiblePosition();
    final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;

    if (pos < firstListItemPosition || pos > lastListItemPosition ) {
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        final int childIndex = pos - firstListItemPosition;
        return listView.getChildAt(childIndex);
    }
}

This can be done using HTML5's placeHolder or using JavaScript. Checkout this post.

I have this setup in my Ubuntu .vimrc. I don't see any swap files in my project files.

set undofile
set undolevels=1000         " How many undos
set undoreload=10000        " number of lines to save for undo

set backup                        " enable backups
set swapfile                      " enable swaps
set undodir=$HOME/.vim/tmp/undo     " undo files
set backupdir=$HOME/.vim/tmp/backup " backups
set directory=$HOME/.vim/tmp/swap   " swap files

" Make those folders automatically if they don't already exist.
if !isdirectory(expand(&undodir))
    call mkdir(expand(&undodir), "p")
endif
if !isdirectory(expand(&backupdir))
    call mkdir(expand(&backupdir), "p")
endif
if !isdirectory(expand(&directory))
    call mkdir(expand(&directory), "p")
endif

Just wanted to point out one thing missing in LazyOne's answer (I would have just commented under the answer but don't have enough rep)

In rule #2 for permanent redirect there is thing missing:

redirectType="Permanent"

So rule #2 should look like this:

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" redirectType="Permanent" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Edit

For more information on how to use the URL Rewrite Module see this excellent documentation: URL Rewrite Module Configuration Reference

In response to @kneidels question from the comments; To match the url: topic.php?id=39 something like the following could be used:

<system.webServer>
  <rewrite>
    <rules>
      <rule name="SpecificRedirect" stopProcessing="true">
        <match url="^topic.php$" />
        <conditions logicalGrouping="MatchAll">
          <add input="{QUERY_STRING}" pattern="(?:id)=(\d{2})" />
        </conditions>
        <action type="Redirect" url="/newpage/{C:1}" appendQueryString="false" redirectType="Permanent" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>

This will match topic.php?id=ab where a is any number between 0-9 and b is also any number between 0-9. It will then redirect to /newpage/xy where xy comes from the original url. I have not tested this but it should work.

for i in iterator:
    try:
        # Do something.
        pass
    except:
        # Continue to next iteration.
        continue

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

Go to the Ant website and download. This way, you have a copy of Ant outside of Eclipse. I recommend to put it under the C:\ant directory. This way, it doesn't have any spaces in the directory names. In your System Control Panel, set the Environment Variable ANT_HOME to this directory, then pre-pend to the System PATHvariable, %ANT_HOME%\bin. This way, you don't have to put in the whole directory name.

Assuming you did the above, try this:

C:\> cd \Silk4J\Automation\iControlSilk4J
C:\Silk4J\Automation\iControlSilk4J> ant -d build

This will do several things:

• It will eliminate the possibility that the problem is with Eclipe's version of Ant.
• It is way easier to type
• Since you're executing the build.xml in the directory where it exists, you don't end up with the possibility that your Ant build can't locate a particular directory.

The -d will print out a lot of output, so you might want to capture it, or set your terminal buffer to something like 99999, and run cls first to clear out the buffer. This way, you'll capture all of the output from the beginning in the terminal buffer.

Let's see how Ant should be executing. You didn't specify any targets to execute, so Ant should be taking the default build target. Here it is:

<target depends="build-subprojects,build-project" name="build"/>

The build target does nothing itself. However, it depends upon two other targets, so these will be called first:

The first target is build-subprojects:

<target name="build-subprojects"/>

This does nothing at all. It doesn't even have a dependency.

The next target specified is build-project does have code:

<target depends="init" name="build-project">

This target does contain tasks, and some dependent targets. Before build-project executes, it will first run the init target:

<target name="init">
    <mkdir dir="bin"/>
    <copy includeemptydirs="false" todir="bin">
        <fileset dir="src">
            <exclude name="**/*.java"/>
        </fileset>
    </copy>
</target>

This target creates a directory called bin, then copies all files under the src tree with the suffix *.java over to the bin directory. The includeemptydirs mean that directories without non-java code will not be created.

Ant uses a scheme to do minimal work. For example, if the bin directory is created, the <mkdir/> task is not executed. Also, if a file was previously copied, or there are no non-Java files in your src directory tree, the <copy/> task won't run. However, the init target will still be executed.

Next, we go back to our previous build-project target:

<target depends="init" name="build-project">
    <echo message="${ant.project.name}: ${ant.file}"/>
    <javac debug="true" debuglevel="${debuglevel}" destdir="bin" source="${source}" target="${target}">
        <src path="src"/>
        <classpath refid="iControlSilk4J.classpath"/>
    </javac>
</target>

Look at this line:

<echo message="${ant.project.name}: ${ant.file}"/>

That should have always executed. Did your output print:

[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

Maybe you didn't realize that was from your build.

After that, it runs the <javac/> task. That is, if there's any files to actually compile. Again, Ant tries to avoid work it doesn't have to do. If all of the *.java files have previously been compiled, the <javac/> task won't execute.

And, that's the end of the build. Your build might not have done anything simply because there was nothing to do. You can try running the clean task, and then build:

C:\Silk4J\Automation\iControlSilk4J> ant -d clean build

However, Ant usually prints the target being executed. You should have seen this:

init:

build-subprojects:

build-projects:

    [echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

build:

Build Successful

Note that the targets are all printed out in order they're executed, and the tasks are printed out as they are executed. However, if there's nothing to compile, or nothing to copy, then you won't see these tasks being executed. Does this look like your output? If so, it could be there's nothing to do.

• If the bin directory already exists, <mkdir/> isn't going to execute.
• If there are no non-Java files in src, or they have already been copied into bin, the <copy/> task won't execute.
• If there are no Java file in your src directory, or they have already been compiled, the <java/> task won't run.

If you look at the output from the -d debug, you'll see Ant looking at a task, then explaining why a particular task wasn't executed. Plus, the debug option will explain how Ant decides what tasks to execute.

See if that helps.

Simple, for python 3.4 and above

print (type(variable_name))

Python 2.7 and above

print type(variable_name)

This is the most efficient way to see if a number is prime, if you only have a few query. If you ask a lot of numbers if they are prime try Sieve of Eratosthenes.

import math

def is_prime(n):
    if n == 2:
        return True
    if n % 2 == 0 or n <= 1:
        return False

    sqr = int(math.sqrt(n)) + 1

    for divisor in range(3, sqr, 2):
        if n % divisor == 0:
            return False
    return True

A little late the the party, but I figured I'd throw my hat in the ring as my solution seems to run faster than OP's (on my machine, anyway):

# [Python 3]
def merge_sort(arr):
    if len(arr) < 2:
        return arr
    half = len(arr) // 2
    left = merge_sort(arr[:half])
    right = merge_sort(arr[half:])
    out = []
    li = ri = 0  # index of next element from left, right halves
    while True:
        if li >= len(left):  # left half is exhausted
            out.extend(right[ri:])
            break
        if ri >= len(right): # right half is exhausted
            out.extend(left[li:])
            break
        if left[li] < right[ri]:
            out.append(left[li])
            li += 1
        else:
            out.append(right[ri])
            ri += 1
    return out

This doesn't have any slow pop()s, and once one of the half-arrays is exhausted, it immediately extends the other one onto the output array rather than starting a new loop.

I know it's machine dependent, but for 100,000 random elements (above merge_sort() vs. Python built-in sorted()):

merge sort: 1.03605 seconds
Python sort: 0.045 seconds
Ratio merge / Python sort: 23.0229

In order to use my example,Your file "abc.txt" needs to look like:

[your-config]
path1 = "D:\test1\first"
path2 = "D:\test2\second"
path3 = "D:\test2\third"

Then in your software you can use the config parser:

import ConfigParser

and then in you code:

 configParser = ConfigParser.RawConfigParser()   
 configFilePath = r'c:\abc.txt'
 configParser.read(configFilePath)

Use case:

self.path = configParser.get('your-config', 'path1')

*Edit (@human.js)

in python 3, ConfigParser is renamed to configparser (as described here)

You can't wrap that text as it's unbroken without any spaces. You need a JavaScript or server side solution which splits the string after a few characters.

EDIT

You need to add this property in CSS.

word-wrap: break-word;

System.Diagnostics.Process.Start("c:\\batchfilename.bat");

this simple line will execute the batch file.

Short version for easy use:

SELECT * 
FROM [TableName] t
WHERE t.[DateColumnName] >= DATEADD(month, -1, GETDATE())

DATEADD and GETDATE are available in SQL Server starting with 2008 version. MSDN documentation: GETDATE and DATEADD.

Regex : ^[\\w!#$%&’*+/=?{|}~^-]+(?:\.[\w!#$%&’*+/=?{|}~^-]+)*@(?:[a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$

public static boolean isValidEmailId(String email) {
        String emailPattern = "^[\\w!#$%&’*+/=?`{|}~^-]+(?:\\.[\\w!#$%&’*+/=?`{|}~^-]+)*@(?:[a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$";
        Pattern p = Pattern.compile(emailPattern);
        Matcher m = p.matcher(email);
        return m.matches();
    }

To see the window height while (or after) it is resized, try it:

$(window).resize(function() {
$('body').prepend('<div>' + $(window).height() - 46 + '</div>');
});

Just found sys.executable - the full path to the current Python executable, which can be used to run the script (instead of relying on the shbang, which obviously doesn't work on Windows)

import sys
import subprocess

theproc = subprocess.Popen([sys.executable, "myscript.py"])
theproc.communicate()

I know it's an old Question, but i think some one can benefit from my solution.

Advantages:

• It separates all the 3 sub-strings deliminator by ' '.
• One must not use while loop, as it decreases the performance.
• No need to Pivot as all the resultant sub-string will be displayed in one Row

Limitations:

• One must know the total no. of spaces (sub-string).

Note: the solution can give sub-string up to to N.

To overcame the limitation we can use the following ref.

But again the above solution can't be use in a table (Actaully i wasn't able to use it).

Again i hope this solution can help some-one.

Update: In case of Records > 50000 it is not advisable to use LOOPS as it will degrade the Performance

If you know your current password, you don't have to stop mysql server. Open the ubuntu terminal. Login to mysql using:

mysql - username -p

Then type your password. This will take you into the mysql console. Inside the console, type:

> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

Then flush privileges using:

> flush privileges;

Then you are all done.

Just like leonbloy suggested, using two schemas in a database is the way to go. Suppose a source schema (old DB) and a target schema (new DB), you can try something like this (you should consider column names, types, etc.):

INSERT INTO target.Awards SELECT * FROM source.Nominations;

How about using sed? It comes standard with most (all?) Linux OS.

sed 's/\t/<your_field_delimiter>/g'.

This example uses GNU sed (Linux). For POSIX sed (AIX/Solaris)I believe you would type a literal TAB instead of \t

Example (for CSV output):

#mysql mysql -B -e "select * from user" | while read; do sed 's/\t/,/g'; done

You can get an idea, how to implement an efficient one, if you don't have any in the library, from here

It use a table for all 256 chars.

• in that table for all chars, except letters - used its ascii codes.
• for upper case letter codes - the table list codes of lower cased symbols.

then we just need to traverse a strings and compare our table cells for a given chars:

const char *cm = charmap,
        *us1 = (const char *)s1,
        *us2 = (const char *)s2;
while (cm[*us1] == cm[*us2++])
    if (*us1++ == '\0')
        return (0);
return (cm[*us1] - cm[*--us2]);
