• go to dosbox installation directory (on my machine that is C:\Program Files (x86)\DOSBox-0.74 ) as you see the version number is part of the installation directory name.

• run "DOSBox 0.74 Options.bat"

• the script starts notepad with configuration file: here change

  windowresolution=1600x800

  output=ddraw

(the resolution can't be changed if output=surface - that's the default).

• safe configuration file changes.

I know that is a old question, but...

You can also use this in your class:

@Autowired
private HttpServletRequest context;

And this will provide the current instance of HttpServletRequest for you use on your method.

We can use odd and even CSS rules and jQuery method for alternate row colors

Using CSS

table tr:nth-child(odd) td{
           background:#ccc;
}
table tr:nth-child(even) td{
            background:#fff;
}

Using jQuery

$(document).ready(function()
{
  $("table tr:odd").css("background", "#ccc");
  $("table tr:even").css("background", "#fff");
});

table tr:nth-child(odd) td{_x000D_
           background:#ccc;_x000D_
}_x000D_
table tr:nth-child(even) td{_x000D_
            background:#fff;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>One</td>_x000D_
    <td>one</td>_x000D_
   </tr>_x000D_
  <tr>_x000D_
    <td>Two</td>_x000D_
    <td>two</td>_x000D_
  </tr>_x000D_
</table>

Whenever I do a merge, I get into the branch I want to merge into (e.g. "git checkout branch-i-am-working-in") and then do the following:

git merge origin/branch-i-want-to-merge-from

You can save the best model using keras.callbacks.ModelCheckpoint()

Example:

model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
model_checkpoint_callback = keras.callbacks.ModelCheckpoint("best_Model.h5",save_best_only=True)
history = model.fit(x_train,y_train,
          epochs=10,
          validation_data=(x_valid,y_valid),
          callbacks=[model_checkpoint_callback])

This will save the best model in your working directory.

You can press q to exit.

git hist is using a pager tool so you can scroll up and down the results before returning to the console.

I am a little late for the show but in case the above answer didn't solve the query then I found another way. Simply remove the specific large file from .pack. I had this issue where I checked in a large 2GB file accidentally. I followed the steps explained in this link: http://www.ducea.com/2012/02/07/howto-completely-remove-a-file-from-git-history/

These posts helped me get past a couple of issues I had creating a CLR Stored Procedure with Restful API call against Infor M3 API.

The XML Result from these API's look like this for my code below:

miResult xmlns="http://lawson.com/m3/miaccess">
    <Program>MMS200MI</Program>
    <Transaction>Get</Transaction>
    <Metadata>...</Metadata>
    <MIRecord>
        <RowIndex>0</RowIndex>
        <NameValue>
            <Name>STAT</Name>
            <Value>20</Value>
        </NameValue>
        <NameValue>
            <Name>ITNO</Name>
            <Value>ITEM123</Value>
        </NameValue>
        <NameValue>
            <Name>ITDS</Name>
            <Value>ITEM DESCRIPTION 123 </Value>
        </NameValue>
...

The CLR C# Code to accomplish listing out the Resultset from the API works as shown below:

Hopefully this provides helpful.

Here's a solution I just came up with for this problem

Original code:

int index=0;
foreach (var item in enumerable)
{
    blah(item, index); // some code that depends on the index
    index++;
}

Updated code

enumerable.ForEach((item, index) => blah(item, index));

Extension Method:

    public static IEnumerable<T> ForEach<T>(this IEnumerable<T> enumerable, Action<T, int> action)
    {
        var unit = new Unit(); // unit is a new type from the reactive framework (http://msdn.microsoft.com/en-us/devlabs/ee794896.aspx) to represent a void, since in C# you can't return a void
        enumerable.Select((item, i) => 
            {
                action(item, i);
                return unit;
            }).ToList();

        return pSource;
    }

According to this article application/xml is preferred.

EDIT

I did a little follow-up on the article.

The author claims that the encoding declared in XML processing instructions, like:

<?xml version="1.0" encoding="UTF-8"?>

can be ignored when text/xml media type is used.

They support the thesis with the definition of text/* MIME type family specification in RFC 2046, specifically the following fragment:

4.1.2.  Charset Parameter

   A critical parameter that may be specified in the Content-Type field
   for "text/plain" data is the character set.  This is specified with a
   "charset" parameter, as in:

     Content-type: text/plain; charset=iso-8859-1

   Unlike some other parameter values, the values of the charset
   parameter are NOT case sensitive.  The default character set, which
   must be assumed in the absence of a charset parameter, is US-ASCII.

   The specification for any future subtypes of "text" must specify
   whether or not they will also utilize a "charset" parameter, and may
   possibly restrict its values as well.  For other subtypes of "text"
   than "text/plain", the semantics of the "charset" parameter should be
   defined to be identical to those specified here for "text/plain",
   i.e., the body consists entirely of characters in the given charset.
   In particular, definers of future "text" subtypes should pay close
   attention to the implications of multioctet character sets for their
   subtype definitions.

According to them, such difficulties can be avoided when using application/xml MIME type. Whether it's true or not, I wouldn't go as far as to avoid text/xml. IMHO, it's best just to follow the semantics of human-readability(non-readability) and always remember to specify the charset.

Here's a few variations that will work.

const oneLiner = (hour = "00", min = "00", sec = "00") => `${(hour % 12) || 12}:${("0" + min).slice(-2)}:${sec} ${(hour < 12) ? 'am' : 'pm'}`_x000D_

Great Example to check the Width and Height using Javascript

https://github.com/AzizAK/ImageRealSize

---Edited is requested from some comments ..

Javascript code:

 function CheckImageSize(){
var image = document.getElementById("Image").files[0];
           createReader(image, function (w, h) {

                alert("Width is: " + w + " And Height is: "+h);
});            
}


  function  createReader(file, whenReady) {
        var reader = new FileReader;
        reader.onload = function (evt) {
            var image = new Image();
            image.onload = function (evt) {
                var width = this.width;
                var height = this.height;
                if (whenReady) whenReady(width, height);
            };
            image.src = evt.target.result;
        };
        reader.readAsDataURL(file);
    }

and HTML code :

<html>
<head>
<title>Image Real Size</title>
<script src="ImageSize.js"></script>
</head>
<body>
<input type="file" id="Image"/>
<input type="button" value="Find the dimensions" onclick="CheckImageSize()"/>
</body>
<html>

Both contain the same functionality but the .min.js equivalent has been optimized in size. You can open both files and take a look at them. In the .min.js file you'll notice that all variables names have been reduced to short names and that most whitespace & comments have been taken out.

As an alternative to the PROGRA~2 method (which is not working for example in IntelliJ IDEA), you can create a symbolic link.

It can be named, for example, prg to Program Files (run mklink /? from the command line to learn how to do it). Then run the emulator as C:\prg\Android\android-sdk\tools\emulator.exe. Also change the path to SDK/emulator in your IDE.

Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).

javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456

Then load the properties to your environment from your code. This makes your application configurable.

FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);

The key information in this error is this line:

This error can be caused by a virtual directory not being configured as an application in IIS.

In IIS, you can have several applications, but they must be configured as an application. Generally, when you create a web project it maps directly to an IIS application.

Check with your hosting service on how to create an IIS application for your web app.

Edit - added If this is on your server, you can set this up yourself following the instructions in @Frazell Thomas's answer. He beat me to finding that link. To save yourself some reading, you should be able to focus in on the Creating Virtual Directories and Local Web Sites section.

if what you need to do is specific only for 1 or 2 pages i suggest to use set_time_limit so it did not affect the whole application.

set_time_limit(some_values);

but ofcourse these 2 values (post_max_size & upload_max_filesize) are subject to investigate.

you either can set it via ini_set function

ini_set('post_max_size','20M');
ini_set('upload_max_filesize','2M');

or directly in php.ini file like response above by Hannes, or even set it iin .htaccess like below

php_value upload_max_filesize 2M
php_value post_max_size 20M

It's called designated initializer which is introduced in C99. It's used to initialize struct or arrays, in this example, struct.

Given

struct point { 
    int x, y;
};

the following initialization

struct point p = { .y = 2, .x = 1 };

is equivalent to the C89-style

struct point p = { 1, 2 };

Your code works fine for me. It replaced the text in the file as expected and didn't append.

If you wanted to append, you set the second parameter in

new FileWriter(fnew,false);

to true;

This solved it for me. easy.

I've added a max validation to amd's great answer.

import { Directive, Input, forwardRef } from '@angular/core'
import { NG_VALIDATORS, Validator, AbstractControl, Validators } from '@angular/forms'

/*
 * This is a wrapper for [min] and [max], used to work with template driven forms
 */

@Directive({
  selector: '[min]',
  providers: [{ provide: NG_VALIDATORS, useExisting: MinNumberValidator, multi: true }]
})
export class MinNumberValidator implements Validator {

  @Input() min: number;

  validate(control: AbstractControl): { [key: string]: any } {
    return Validators.min(this.min)(control)
  }
}

@Directive({
  selector: '[max]',
  providers: [{ provide: NG_VALIDATORS, useExisting: MaxNumberValidator, multi: true }]
})
export class MaxNumberValidator implements Validator {

  @Input() max: number;

  validate(control: AbstractControl): { [key: string]: any } {
    return Validators.max(this.max)(control)
  }
}

not Error:

JSONObject json1 = getJsonX();

Error:

JSONObject json2 = null;
if(x == y)
   json2 = getJSONX();

Error: Local variable statement defined in an enclosing scope must be final or effectively final.

But you can write:

JSONObject json2 = (x == y) ? json2 = getJSONX() : null;

In mij case the ViewController.h/m where in a lib. The projects still builds but since Xcode 6.3 the above error was shown at run-time. Moving both files back into the project solved the issue.

Facebook use the following algorithm to position their login popup window:

function PopupCenter(url, title, w, h) {
  var userAgent = navigator.userAgent,
      mobile = function() {
        return /\b(iPhone|iP[ao]d)/.test(userAgent) ||
          /\b(iP[ao]d)/.test(userAgent) ||
          /Android/i.test(userAgent) ||
          /Mobile/i.test(userAgent);
      },
      screenX = typeof window.screenX != 'undefined' ? window.screenX : window.screenLeft,
      screenY = typeof window.screenY != 'undefined' ? window.screenY : window.screenTop,
      outerWidth = typeof window.outerWidth != 'undefined' ? window.outerWidth : document.documentElement.clientWidth,
      outerHeight = typeof window.outerHeight != 'undefined' ? window.outerHeight : document.documentElement.clientHeight - 22,
      targetWidth = mobile() ? null : w,
      targetHeight = mobile() ? null : h,
      V = screenX < 0 ? window.screen.width + screenX : screenX,

}

There is a jQuery plugin for this exact purpose: https://github.com/dubbs/equal-height

If you want to make all columns the same height, use:

$('.columns').equalHeight();

If you want to group them by their top position, eg. within each container:

$('.columns').equalHeight({ groupByTop: true });

Eric Petroelje almost has it right:

SELECT * FROM TableA
WHERE ROWID IN ( SELECT MAX(ROWID) FROM TableA GROUP BY Language )

Note: using ROWID (row unique id), not ROWNUM (which gives the row number within the result set)

I would use Pandas with col number

f = pd.read_csv("test.csv", usecols=[0,1,3,4])

f.to_csv("test.csv", index=False)

There's also the DateTime class which implements a function for comparison operators.

// $now = new DateTime();
$dtA = new DateTime('05/14/2010 3:00PM');
$dtB = new DateTime('05/14/2010 4:00PM');

if ( $dtA > $dtB ) {
  echo 'dtA > dtB';
}
else {
  echo 'dtA <= dtB';
}

No need for a regex here, if you just want to replace a piece of string by another: using str_replace() should be more than enough :

$new = str_replace(' ', '%20', $your_string);

But, if you want a bit more than that, and you probably do, if you are working with URLs, you should take a look at the urlencode() function.

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

Turned out there was some extra code in the AppModel that was messing things up:

in beforeFind and afterFind:

App::Import("Session");
$session = new CakeSession();
$sim_id = $session->read("Simulation.id");

I don't know why, but that was what the problem was. Removing those lines fixed the issue I was having.

This not the best way to manage session in react you can use web tokens to encrypt your data that you want save,you can use various number of services available a popular one is JSON web tokens(JWT) with web-tokens you can logout after some time if there no action from the client And after creating the token you can store it in your local storage for ease of access.

jwt.sign({user}, 'secretkey', { expiresIn: '30s' }, (err, token) => {
    res.json({
      token
  });

user object in here is the user data which you want to keep in the session

localStorage.setItem('session',JSON.stringify(token));

You override $today in the if statement.

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

It is then not a Date() object anymore - hence the error.

If using java8, just convert array to stream, sort and convert back. All of the tasks can be done just in one line, so I feel this way is not too bad.

double[] nums = Arrays.stream(nums).boxed().
        .sorted((i1, i2) -> Double.compare(i2, i1))
        .mapToDouble(Double::doubleValue)
        .toArray();

Your best option will be to create a simple data structure to model what you have. Then you can store these objects in a simple list and sort/retrieve them any way you wish.

For this case, I'd use the following class:

class Fruit:
    def __init__(self, name, color, quantity): 
        self.name = name
        self.color = color
        self.quantity = quantity

    def __str__(self):
        return "Name: %s, Color: %s, Quantity: %s" % \
     (self.name, self.color, self.quantity)

Then you can simply construct "Fruit" instances and add them to a list, as shown in the following manner:

fruit1 = Fruit("apple", "red", 12)
fruit2 = Fruit("pear", "green", 22)
fruit3 = Fruit("banana", "yellow", 32)
fruits = [fruit3, fruit2, fruit1] 

The simple list fruits will be much easier, less confusing, and better-maintained.

Some examples of use:

All outputs below is the result after running the given code snippet followed by:

for fruit in fruits:
    print fruit

Unsorted list:

Displays:

Name: banana, Color: yellow, Quantity: 32
Name: pear, Color: green, Quantity: 22
Name: apple, Color: red, Quantity: 12

Sorted alphabetically by name:

fruits.sort(key=lambda x: x.name.lower())

Displays:

Name: apple, Color: red, Quantity: 12
Name: banana, Color: yellow, Quantity: 32
Name: pear, Color: green, Quantity: 22

Sorted by quantity:

fruits.sort(key=lambda x: x.quantity)

Displays:

Name: apple, Color: red, Quantity: 12
Name: pear, Color: green, Quantity: 22
Name: banana, Color: yellow, Quantity: 32

Where color == red:

red_fruit = filter(lambda f: f.color == "red", fruits)

Displays:

Name: apple, Color: red, Quantity: 12

Simple like that:

date("Y-m-d", strtotime("-1 day"));

date("Y-m-d", strtotime("-1 months"))

For a bit more flexibility than with micronyks answer, you can do it like that:

1. In your template, add #myIdentifier to the element you want to obtain the width from. Example:

<p #myIdentifier>
  my-component works!
</p>

2. In your controller, you can use this with @ViewChild('myIdentifier') to get the width:

import {AfterViewInit, Component, ElementRef, OnInit, ViewChild} from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})
export class MyComponentComponent implements AfterViewInit {

  constructor() { }

  ngAfterViewInit() {
    console.log(this.myIdentifier.nativeElement.offsetWidth);
  }

  @ViewChild('myIdentifier')
  myIdentifier: ElementRef;

}

Security

About the security risk with ElementRef, like this, there is none. There would be a risk, if you would modify the DOM using an ElementRef. But here you are only getting DOM Elements so there is no risk. A risky example of using ElementRef would be: this.myIdentifier.nativeElement.onclick = someFunctionDefinedBySomeUser;. Like this Angular doesn't get a chance to use its sanitisation mechanisms since someFunctionDefinedBySomeUser is inserted directly into the DOM, skipping the Angular sanitisation.

I posted an answer a while back here that you could use here. The outline is:

• Create a temp table
• Call sp_msForEachDb
• The query run against each DB stores the data in the temp table
• When done, query the temp table

In our case we had a query which loads multiple items with select * from x where something in (...) The in part was so long for benchmark test.(17mb as text query). Query is valid but text so long. Shortening the query solved the problem.

Don't run it though addslashes(); if you're in the context of the HTML page, the HTML parser can still see the </script> tag, even mid-string, and assume it's the end of the JavaScript:

<?php
    $value = 'XXX</script><script>alert(document.cookie);</script>';
?>

<script type="text/javascript">
    var foo = <?= json_encode($value) ?>; // Use this
    var foo = '<?= addslashes($value) ?>'; // Avoid, allows XSS!
</script>

Try something like this:

<form action="/" id="searchForm">
<input type="text" name="s" placeholder="Search...">
<input type="submit" value="Search">
</form>
<!-- the result of the search will be rendered inside this div -->
<div id="result"></div>

<script>
// Attach a submit handler to the form
$( "#searchForm" ).submit(function( event ) {

  // Stop form from submitting normally
event.preventDefault();

// Get some values from elements on the page:
var $form = $( this ),
term = $form.find( "input[name='s']" ).val(),
url = $form.attr( "action" );

// Send the data using post
var posting = $.post( url, { s: term } );

// Put the results in a div
posting.done(function( data ) {
  var content = $( data ).find( "#content" );
  $( "#result" ).empty().append( content );
    });
  });
</script>

Note the use of input[]

Func - When you want a delegate for a function that may or may not take parameters and returns a value. The most common example would be Select from LINQ:

var result = someCollection.Select( x => new { x.Name, x.Address });

Action - When you want a delegate for a function that may or may not take parameters and does not return a value. I use these often for anonymous event handlers:

button1.Click += (sender, e) => { /* Do Some Work */ }

Predicate - When you want a specialized version of a Func that evaluates a value against a set of criteria and returns a boolean result (true for a match, false otherwise). Again, these are used in LINQ quite frequently for things like Where:

var filteredResults = 
    someCollection.Where(x => x.someCriteriaHolder == someCriteria);

I just double checked and it turns out that LINQ doesn't use Predicates. Not sure why they made that decision...but theoretically it is still a situation where a Predicate would fit.

I did this

~]$ export A=g

~]$ export B=!

~]$ export C=nger


   curl http://<>USERNAME<>1:$A$B$C@<>URL<>/<>PATH<>/

In Windows, you can use any combination of red green and blue on the foreground (text) and the background.

/* you can use these constants
FOREGROUND_BLUE
FOREGROUND_GREEN
FOREGROUND_RED
FOREGROUND_INTENSITY
BACKGROUND_BLUE
BACKGROUND_GREEN
BACKGROUND_RED
BACKGROUND_INTENSITY
*/

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
std::cout << "I'm cyan! Who are you?" << std::endl;

Try just this without the span tag:

<option selected="selected" class="grey_color">select one option</option>

For bigger flexibility you can use any JS widget.

<div ng-hide="myvar == null"></div>

or

<div ng-show="myvar != null"></div>

sys.argv represents the command line options you execute a script with.

sys.argv[0] is the name of the script you are running. All additional options are contained in sys.argv[1:].

You are attempting to open a file that uses sys.argv[1] (the first argument) as what looks to be the directory.

Try running something like this:

python ConcatenateFiles.py /tmp

After struggling with this issue for some time and researching about it, I finally managed to solve it following these steps:

1) install jdk version 12
2) Create new variable in systems variable
3) Name it as JAVA_HOME and give jdk installation path
4) add this variable in path and move it to top.
5) go to C:\Program Files (86)\Common Files\Oracle\Java\javapath and replace java.exe and javaw.exe with the corresponding files with the same names from the pathtojavajdk/bin folder

Finally, I checked the default version of java in cmd with "java -version" and it worked!

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

This worked fine for me

int  max = Convert.ToInt32(datatable_name.AsEnumerable()
                        .Max(row => row["column_Name"]));

Modernizr.js will remove the no-js class.

This allows you to make CSS rules for .no-js something to apply them only if Javascript is disabled.

All the technical talking is overcomplicating the concept.

If you put GC into C++ for all the memory automatically then consider something like a web browser. The web browser must load a full web document AND run web scripts. You can store web script variables in the document tree. In a BIG document in a browser with lots of tabs open, it means that every time the GC must do a full collection it must also scan all the document elements.

On most computers this means that PAGE FAULTS will occur. So the main reason, to answer the question is that PAGE FAULTS will occur. You will know this as when your PC starts making lots of disk access. This is because the GC must touch lots of memory in order to prove invalid pointers. When you have a bona fide application using lots of memory, having to scan all objects every collection is havoc because of the PAGE FAULTS. A page fault is when virtual memory needs to get read back into RAM from disk.

So the correct solution is to divide an application into the parts that need GC and the parts that do not. In the case of the web browser example above, if the document tree was allocated with malloc, but the javascript ran with GC, then every time the GC kicks in it only scans a small portion of memory and all PAGED OUT elements of the memory for the document tree does not need to get paged back in.

To further understand this problem, look up on virtual memory and how it is implemented in computers. It is all about the fact that 2GB is available to the program when there is not really that much RAM. On modern computers with 2GB RAM for a 32BIt system it is not such a problem provided only one program is running.

As an additional example, consider a full collection that must trace all objects. First you must scan all objects reachable via roots. Second scan all the objects visible in step 1. Then scan waiting destructors. Then go to all the pages again and switch off all invisible objects. This means that many pages might get swapped out and back in multiple times.

So my answer to bring it short is that the number of PAGE FAULTS which occur as a result of touching all the memory causes full GC for all objects in a program to be unfeasible and so the programmer must view GC as an aid for things like scripts and database work, but do normal things with manual memory management.

And the other very important reason of course is global variables. In order for the collector to know that a global variable pointer is in the GC it would require specific keywords, and thus existing C++ code would not work.

Following are the steps to push Docker Image to Private Repository of DockerHub

1- First check Docker Images using command

docker images

2- Check Docker Tag command Help

docker tag help

3- Now Tag a name to your created Image

docker tag localImgName:tagName DockerHubUser\Private-repoName:tagName(tag name is optional. Default name is latest)

4- Before pushing Image to DockerHub Private Repo, first login to DockerHub using command

docker login [provide dockerHub username and Password to login]

5- Now push Docker Image to your private Repo using command

docker push [options] ImgName[:tag] e.g docker push DockerHubUser\Private-repoName:tagName

6- Now navigate to the DockerHub Private Repo and you will see Docker image is pushed on your private Repository with name written as TagName in previous steps

With CentOS, you can do it using a combination of fastcgi for one version of PHP, and php-fpm for the other, as described here:

https://web.archive.org/web/20130707085630/http://linuxplayer.org/2011/05/intall-multiple-version-of-php-on-one-server

Based on CentOS 5.6, for Apache only

1. Enable rpmforge and epel yum repository

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
wget http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
sudo rpm -ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
sudo rpm -ivh epel-release-5-4.noarch.rpm

2. Install php-5.1

CentOS/RHEL 5.x series have php-5.1 in box, simply install it with yum, eg:

sudo yum install php php-mysql php-mbstring php-mcrypt

3. Compile and install php 5.2 and 5.3 from source

For php 5.2 and 5.3, we can find many rpm packages on the Internet. However, they all conflict with the php which comes with CentOS, so, we’d better build and install them from soure, this is not difficult, the point is to install php at different location.

However, when install php as an apache module, we can only use one version of php at the same time. If we need to run different version of php on the same server, at the same time, for example, different virtual host may need different version of php. Fortunately, the cool FastCGI and PHP-FPM can help.

Build and install php-5.2 with fastcgi enabled

1) Install required dev packages

yum install gcc libxml2-devel bzip2-devel zlib-devel \
    curl-devel libmcrypt-devel libjpeg-devel \
    libpng-devel gd-devel mysql-devel

2) Compile and install

wget http://cn.php.net/get/php-5.2.17.tar.bz2/from/this/mirror
tar -xjf php-5.2.17.tar.bz2
cd php-5.2.17
./configure --prefix=/usr/local/php52 \
    --with-config-file-path=/etc/php52 \
    --with-config-file-scan-dir=/etc/php52/php.d \
    --with-libdir=lib64 \
    --with-mysql \
    --with-mysqli \
    --enable-fastcgi \
    --enable-force-cgi-redirect \
    --enable-mbstring \
    --disable-debug \
    --disable-rpath \
    --with-bz2 \
    --with-curl \
    --with-gettext \
    --with-iconv \
    --with-openssl \
    --with-gd \
    --with-mcrypt \
    --with-pcre-regex \
    --with-zlib
make -j4 > /dev/null
sudo make install
sudo mkdir /etc/php52
sudo cp php.ini-recommended /etc/php52/php.ini

3) create a fastcgi wrapper script

create file /usr/local/php52/bin/fcgiwrapper.sh

#!/bin/bash
PHP_FCGI_MAX_REQUESTS=10000
export PHP_FCGI_MAX_REQUESTS
exec /usr/local/php52/bin/php-cgi
chmod a+x /usr/local/php52/bin/fcgiwrapper.sh
Build and install php-5.3 with fpm enabled

wget http://cn.php.net/get/php-5.3.6.tar.bz2/from/this/mirror
tar -xjf php-5.3.6.tar.bz2 
cd php-5.3.6
./configure --prefix=/usr/local/php53 \
    --with-config-file-path=/etc/php53 \
    --with-config-file-scan-dir=/etc/php53/php.d \
    --enable-fpm \
    --with-fpm-user=apache \
    --with-fpm-group=apache \
    --with-libdir=lib64 \
    --with-mysql \
    --with-mysqli \
    --enable-mbstring \
    --disable-debug \
    --disable-rpath \
    --with-bz2 \
    --with-curl \
    --with-gettext \
    --with-iconv \
    --with-openssl \
    --with-gd \
    --with-mcrypt \
    --with-pcre-regex \
    --with-zlib 

make -j4 && sudo make install
sudo mkdir /etc/php53
sudo cp php.ini-production /etc/php53/php.ini

sed -i -e 's#php_fpm_CONF=\${prefix}/etc/php-fpm.conf#php_fpm_CONF=/etc/php53/php-fpm.conf#' \
    sapi/fpm/init.d.php-fpm
sudo cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
sudo chmod a+x /etc/init.d/php-fpm
sudo /sbin/chkconfig --add php-fpm
sudo /sbin/chkconfig php-fpm on

sudo cp sapi/fpm/php-fpm.conf /etc/php53/

Configue php-fpm

Edit /etc/php53/php-fpm.conf, change some settings. This step is mainly to uncomment some settings, you can adjust the value if you like.

pid = run/php-fpm.pid
listen = 127.0.0.1:9000
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 20

Then, start fpm

sudo /etc/init.d/php-fpm start

Install and setup mod_fastcgi, mod_fcgid

sudo yum install libtool httpd-devel apr-devel
wget http://www.fastcgi.com/dist/mod_fastcgi-current.tar.gz
tar -xzf mod_fastcgi-current.tar.gz
cd mod_fastcgi-2.4.6
cp Makefile.AP2 Makefile
sudo make top_dir=/usr/lib64/httpd/ install
sudo sh -c "echo 'LoadModule fastcgi_module modules/mod_fastcgi.so' > /etc/httpd/conf.d/mod_fastcgi.conf"
yum install mod_fcgid

Setup and test virtual hosts

1) Add the following line to /etc/hosts

127.0.0.1 web1.example.com web2.example.com web3.example.com

2) Create web document root and drop an index.php under it to show phpinfo switch to user root, run

mkdir /var/www/fcgi-bin
for i in {1..3}; do
    web_root=/var/www/web$i
    mkdir $web_root
    echo "<?php phpinfo(); ?>" > $web_root/index.php
done

Note: The empty /var/www/fcgi-bin directory is required, DO NOT REMOVE IT LATER

3) Create Apache config file(append to httpd.conf)

NameVirtualHost *:80

# module settings
# mod_fcgid
<IfModule mod_fcgid.c>
        idletimeout 3600
        processlifetime 7200

4) restart apache. visit the 3 sites respectly to view phpinfo and validate the result. ie:

If all OK, you can use one of the 3 virtual host as template to create new virtual host, with the desired php version.

Difference between Bean and Component:

The answer given by deepak goel does not work for me because I always get null from entry.getName();

What I do is to set a Tag to the fragment this way:

ft.add(R.id.fragment_container, fragmentIn, FRAGMENT_TAG);

Where ft is my fragment transaction and FRAGMENT_TAG is the tag. Then I use this code to get the fragment:

Fragment prev_fragment = fragmentManager.findFragmentByTag(FRAGMENT_TAG);

As noted in the accepted answer - you can use the special { props.children } property. However - you can just pass a component as a prop as the title requests. I think this is cleaner sometimes as you might want to pass several components and have them render in different places. Here's the react docs with an example of how to do it:

https://reactjs.org/docs/composition-vs-inheritance.html

Make sure you are actually passing a component and not an object (this tripped me up initially).

The code is simply this:

const Parent = () => { 
  return (
    <Child  componentToPassDown={<SomeComp />}  />
  )
}

const Child = ({ componentToPassDown }) => { 
  return (
    <>
     {componentToPassDown}  
    </>
  )
}

If you're registering a domain and the termination (ex .com) it is not IDN, as Aaron Hathaway said: Hostnames are composed of series of labels concatenated with dots, as are all domain names. For example, en.wikipedia.org is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname (including the delimiting dots but not a trailing dot) has a maximum of 253 ASCII characters.

The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters a through z (in a case-insensitive manner), the digits 0 through 9, and the hyphen -. The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.

Later, Spain with it's .es, .com.es, .org.es, .nom,es, .gob.es and .edu.es introduced IDN tlds, if your tld is one of .es or any other that supports it, any character can be used, but you can't combine alphabets like Latin, Greek or Cyril in one hostname, and that it respects the things that can't go at the start or at the end.

If you're using non-registered tlds, just for local networking, like with local DNS or with hosts files, you can treat them all as IDN.

Keep in mind some programs could not work well, especially old, outdated and unpopular ones.

Maybe this small Typescript code example will help.

private getAccount(id: Id) : Account {
    let account = Account.empty();
    this.repository.get(id)
        .then(res => account = res)
        .catch(e => Notices.results(e));
    return account;
}

Here the repository.get(id) returns a Promise<Account>. I assign it to the variable account within the then statement.

Go to [Tool Window\Project] by Alt+1, and change the level on the top-left corner of this window to Project (the other two are Packages and Android), then you can rename the Project name by Shift+F6. Type in the new name and press OK.

If you just want to change the app name which appears in the system, you can modify the android:title in the manifest.xml.

Try to locate the bin>www location and try to change the port number...

That's an easy one:

[aView convertPoint:localPosition toView:nil];

... converts a point in local coordinate space to window coordinates. You can use this method to calculate a view's origin in window space like this:

[aView.superview convertPoint:aView.frame.origin toView:nil];

2014 Edit: Looking at the popularity of Matt__C's comment it seems reasonable to point out that the coordinates...

1. don't change when rotating the device.
2. always have their origin in the top left corner of the unrotated screen.
3. are window coordinates: The coordinate system ist defined by the bounds of the window. The screen's and device coordinate systems are different and should not be mixed up with window coordinates.

You can also let Square's Picasso library do the heavy lifting:

Picasso
    .get()
    .load("http://...")
    .into(imageView);

As a bonus, you get caching, transformations, and more.

If you want to do something like the following example, you'd have to use nested ifs.

If percentage is greater than or equal to 93%, then corresponding value in B should be 4 and if the percentage is greater than or equal to 90% and less than 92%, then corresponding value in B to be 3.7, etc.

Here's how you'd do it:

=IF(A2>=93%, 4, IF(A2>=90%, 3.7,IF(A2>=87%,3.3,0)))

In your .m file, declare a file global variable:

static int currentID = 1;

then in your init routine, refernce that:

- (id) init
{
    self = [super init];
    if (self != nil) {
        _myID = currentID++; // not thread safe
    }
    return self;
}

or if it needs to change at some other time (eg in your openConnection method), then increment it there. Remember it is not thread safe as is, you'll need to do syncronization (or better yet, use an atomic add) if there may be any threading issues.

Another way to deal with this kind of problem is to use Exception().

for ii in range(200):
    try:
        for jj in range(200, 400):
            ...block0...
            if something:
                raise Exception()
    except Exception:
        continue
    ...block1...

For example:

for n in range(1,4):
    for m in range(1,4):
        print n,'-',m

result:

    1-1
    1-2
    1-3
    2-1
    2-2
    2-3
    3-1
    3-2
    3-3

Assuming we want to jump to the outer n loop from m loop if m =3:

for n in range(1,4):
    try:
        for m in range(1,4):
            if m == 3:
                raise Exception()            
            print n,'-',m
    except Exception:
        continue

result:

    1-1
    1-2
    2-1
    2-2
    3-1
    3-2

Using Accept header is really easy to get the format json or xml from the REST service.

This is my Controller, take a look produces section.

@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
    public UIProperty getProperties() {
        return uiProperty;
    }

In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE

HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);

HttpEntity entity = new HttpEntity(headers);

RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();

Edit 01:

In order to work with application/xml, add this dependency

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>

This is how I implemented my strcmp: it works like this: it compares first letter of the two strings, if it is identical, it continues to the next letter. If not, it returns the corresponding value. It is very simple and easy to understand: #include

//function declaration:
int strcmp(char string1[], char string2[]);

int main()
{
    char string1[]=" The San Antonio spurs";
    char string2[]=" will be champins again!";
    //calling the function- strcmp
    printf("\n number returned by the strcmp function: %d", strcmp(string1, string2));
    getch();
    return(0);
}

/**This function calculates the dictionary value of the string and compares it to another string.
it returns a number bigger than 0 if the first string is bigger than the second
it returns a number smaller than 0 if the second string is bigger than the first
input: string1, string2
output: value- can be 1, 0 or -1 according to the case*/
int strcmp(char string1[], char string2[])
{
    int i=0;
    int value=2;    //this initialization value could be any number but the numbers that can be      returned by the function
    while(value==2)
    {
        if (string1[i]>string2[i])
        {
            value=1;
        }
        else if (string1[i]<string2[i])
        {
            value=-1;
        }
        else
        {
            i++;
        }
    }
    return(value);
}

You can use:

sc.sparkContext.getConf.getAll

For example, I often have the following at the top of my Spark programs:

logger.info(sc.sparkContext.getConf.getAll.mkString("\n"))

The quick answer is User = System.Web.HttpContext.Current.User

Ensure your web.config has the following authentication element.

<configuration>
    <system.web>
        <authentication mode="Windows" />
        <authorization>
            <deny users="?"/>
        </authorization>
    </system.web>
</configuration>

yes, you can swap these 2 queries

select * from table limit 5, 5

select * from table limit 0, 5

Ok. So, I know this is an old post, but perhaps this can help someone else. This is not backwards compatible, but that's almost irrelevant since Internet Explorer is being made redundant.

Easiest way to do exactly what is wanted:

function findInJson(objJsonResp, key, value, aType){        
     if(aType=="edit"){
        return objJsonResp.find(x=> x[key] == value);
     }else{//delete
         var a =objJsonResp.find(x=> x[key] == value);
         objJsonResp.splice(objJsonResp.indexOf(a),1);
     }
}

It will return the item you want to edit if you supply 'edit' as the type. Supply anything else, or nothing, and it assumes delete. You can flip the conditionals if you'd prefer.

ViewBag is a dynamic type that allow you to dynamically set or get values and allow you to add any number of additional fields without a strongly-typed class They allow you to pass data from controller to view. In controller......

public ActionResult Index()
{
    ViewBag.victor = "My name is Victor";
    return View();
}

In view

@foreach(string a in ViewBag.victor)
{
     .........
}

What I have learnt is that both should have the save dynamic name property ie ViewBag.victor

this query return last record for every Form_id:

    SELECT m1.*
     FROM messages m1 LEFT JOIN messages m2
     ON (m1.Form_id = m2.Form_id AND m1.id < m2.id)
     WHERE m2.id IS NULL;

First of all you have to include your font in your website (or your CSS, to be more specific) using an appropriate @font-face rule.
From here on there are multiple ways to proceed. One thing I would not do is to edit the bootstrap.css directly - since once you get a newer version your changes will be lost. You do however have the possibility to customize your bootstrap files (there's a customize page on their website). Just enter the name of your font with all the fallback names into the corresponding typography textbox. Of course you will have to do this whenever you get a new or updated version of your bootstrap files.
Another chance you have is to overwrite the bootstrap rules within a different stylesheet. If you do this you just have to use selectors that are as specific as (or more specific than) the bootstrap selectors.
Side note: If you care about browser support a single EOT version of your font might not be sufficient. See http://caniuse.com/eot for a support table.

INSERT INTO `table` ( `data` , `date` ) VALUES('".$data."',NOW()+INTERVAL 1 DAY);

For a dummy programming analogy, you can think of Docker has a abstract ImageFactory which holds ImageFactories they come from store.

Then once you want to create an app out of that ImageFactory, you will have a new container, and you can modify it as you want. DotNetImageFactory will be immutable, because it acts as a abstract factory class, where it only delivers instances you desire.

IContainer newDotNetApp = ImageFactory.DotNetImageFactory.CreateNew(appOptions);
newDotNetApp.ChangeDescription("I am making changes on this instance");
newDotNetApp.Run();

Following piece of code, I have prepared for generating the HTML file for documentation which includes Table Name and Purpose in each table and Table Metadata information. It might be helpful!

Consider a solution that will neatly handle arbitrarily many tables.

//ASSUMPTION: All tables must have the same columns
var tables = new List<DataTable>();
tables.Add(oneTableToRuleThemAll);
tables.Add(oneTableToFindThem);
tables.Add(oneTableToBringThemAll);
tables.Add(andInTheDarknessBindThem);
//Or in the real world, you might be getting a collection of tables from some abstracted data source.

//behold, a table too great and terrible to imagine
var theOneTable = tables.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();

Encapsulated into a helper for future reuse:

public static DataTable CombineDataTables(params DataTable[] args)
{
    return args.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();
}

Just have a few tables declared in code?

var combined = CombineDataTables(dt1,dt2,dt3);

Want to combine into one of the existing tables instead of creating a new one?

dt1 = CombineDataTables(dt1,dt2,dt3);

Already have a collection of tables, instead of declared one by one?

//Pretend variable tables already exists
var tables = new[] { dt1, dt2, dt3 };
var combined = CombineDataTables(tables);

The CORS spec is all-or-nothing. It only supports *, null or the exact protocol + domain + port: http://www.w3.org/TR/cors/#access-control-allow-origin-response-header

Your server will need to validate the origin header using the regex, and then you can echo the origin value in the Access-Control-Allow-Origin response header.

mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

You can use the

jar tf example.jar

The presence of the n option attached to the -k5 causes the global -r option to be ignored for that field. You have to specify both n and r at the same level (globally or locally).

sort -t $'\t' -k5,5rn

or

sort -rn -t $'\t' -k5,5

Actually the list of parameters could be accessed with $1 $2 ... etc.
Which is exactly equivalent to:

${!i}

So, the list of parameters could be changed with set,
and ${!i} is the correct way to access them:

$ set -- aa bb cc dd 55 ff gg hh ii jjj kkk lll
$ for ((i=0;i<=$#;i++)); do echo "$#" "$i" "${!i}"; done

12 1 aa
12 2 bb
12 3 cc
12 4 dd
12 5 55
12 6 ff
12 7 gg
12 8 hh
12 9 ii
12 10 jjj
12 11 kkk
12 12 lll

For your specific case, this could be used (without the need for arrays), to set the list of arguments when none was given:

if [ "$#" -eq 0 ]; then
    set -- defaultarg1 defaultarg2
fi

which translates to this even simpler expression:

[ "$#" == "0" ] && set -- defaultarg1 defaultarg2

Check the below code hope that you get your parameter

echo $this->uri->segment('3');

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

div {_x000D_
    width: 200px;_x000D_
    height: 50px;_x000D_
    line-height: 50px;_x000D_
    text-align: center;_x000D_
    color: white;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
}_x000D_
_x000D_
div.a {_x000D_
  box-shadow: 10px 10px 10px #000;_x000D_
}_x000D_
_x000D_
div.b {_x000D_
  box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);_x000D_
}

<div class="a">100% black shadow</div>_x000D_
<div class="b">50% black shadow</div>

I would use

x = 'default' if not x else x

Much shorter than all of your alternatives suggested here, and straight to the point. Read, "set x to 'default' if x is not set otherwise keep it as x." If you need None, 0, False, or "" to be valid values however, you will need to change this behavior, for instance:

valid_vals = ("", 0, False) # We want None to be the only un-set value

x = 'default' if not x and x not in valid_vals else x

This sort of thing is also just begging to be turned into a function you can use everywhere easily:

setval_if = lambda val: 'default' if not val and val not in valid_vals else val

at which point, you can use it as:

>>> x = None # To set it to something not valid
>>> x = setval_if(x) # Using our special function is short and sweet now!
>>> print x # Let's check to make sure our None valued variable actually got set
'default'

Finally, if you are really missing your Ruby infix notation, you could overload ||=| (or something similar) by following this guy's hack: http://code.activestate.com/recipes/384122-infix-operators/

Create a configuration file and put your entries there.

SERVER_PORT=10000     
THREAD_POOL_COUNT=3     
ROOT_DIR=/home/   

You can load this file using Properties.load(fileName) and retrieved values you get(key);

You are looking for the cp command. You need to change directories so that you are outside of the directory you are trying to copy.

If the directory you're copying is called dir1 and you want to copy it to your /home/Pictures folder:

cp -r dir1/ ~/Pictures/

Linux is case-sensitive and also needs the / after each directory to know that it isn't a file. ~ is a special character in the terminal that automatically evaluates to the current user's home directory. If you need to know what directory you are in, use the command pwd.

When you don't know how to use a Linux command, there is a manual page that you can refer to by typing:

man [insert command here]

at a terminal prompt.

Also, to auto complete long file paths when typing in the terminal, you can hit Tab after you've started typing the path and you will either be presented with choices, or it will insert the remaining part of the path.

To merge the sets in the array Sets, you can do

var Sets = [set1, set2, set3];

var merged = new Set([].concat(...Sets.map(set => Array.from(set))));

It is slightly mysterious to me why the following, which should be equivalent, fails at least in Babel:

var merged = new Set([].concat(...Sets.map(Array.from)));

Use Keystore Explorer gui - http://keystore-explorer.sourceforge.net/ - allows you to extract the private key from a .jks in various formats.

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

To compile you could just initiate a shell call to the csc compiler. You may have a headache trying to keep your paths and switches straight but it certainly can be done.

C# Corner Shell Examples

EDIT: Or better yet, use the CodeDOM as Noldorin suggested...

So that I can ask it to get me the content/text in the div tag with class='container' contained within the body tag, Or something similar.

try: 
    from BeautifulSoup import BeautifulSoup
except ImportError:
    from bs4 import BeautifulSoup
html = #the HTML code you've written above
parsed_html = BeautifulSoup(html)
print(parsed_html.body.find('div', attrs={'class':'container'}).text)

You don't need performance descriptions I guess - just read how BeautifulSoup works. Look at its official documentation.

You shall pass a this pointer to tell the function which object to work on because it relies on that as opposed to a static member function.

If nodejs and using express the below code works...

res.set('Content-Type', 'text/css');

<a href="file://server/directory/file.xlsx" target="_blank"> if I remember correctly.

If you only need to look at the cells that are in use you can use:

sub IterateCells()

   For Each Cell in ActiveSheet.UsedRange.Cells
      'do some stuff
   Next

End Sub

that will hit everything in the range from A1 to the last cell with data (the bottom right-most cell)

It will redirect your store page to your contact page

    <IfModule mod_rewrite.c>
    RewriteEngine On 
    RewriteBase /
    Redirect 301 /storepage /contactpage
    </IfModule>

Assuming you are using ssh to connect rsync, what about to send a ssh command before:

ssh user@server mkdir -p existingdir/newdir

if it already exists, nothing happens

Value of %TEMP% environment variable is often user-specific and Windows sets it up with regard to currently logged in user account. Some user accounts may have no user profile, for example when your process runs as a service on SYSTEM, LOCALSYSTEM or other built-in account, or is invoked by IIS application with AppPool identity with Create user profile option disabled. So even when you do not overwrite %TEMP% variable explicitly, Windows may use c:\temp or even c:\windows\temp folders for, lets say, non-usual user accounts. And what's more important, process might have no access rights to this directory!

Xcode 8.2.1 • Swift 3.0.2

let documentDirectoryURL =  try! FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)

let documentDirectoryURL =  try! NSFileManager.defaultManager().URLForDirectory(.DocumentDirectory, inDomain: .UserDomainMask, appropriateForURL: nil, create: true)

The transition component of this function worked really poorly for me in Chrome (didn't test elsewhere). I would resize the window a bunch and my element would sort of scoot around slowly, trying to catch up.

So the following function comments that part out. In addition, I added parameters for passing in optional x & y booleans, if you want to center vertically but not horizontally, for example:

// Center an element on the screen
(function($){
  $.fn.extend({
    center: function (x,y) {
      // var options =  $.extend({transition:300, minX:0, minY:0}, options);
      return this.each(function() {
                if (x == undefined) {
                    x = true;
                }
                if (y == undefined) {
                    y = true;
                }
                var $this = $(this);
                var $window = $(window);
                $this.css({
                    position: "absolute",
                });
                if (x) {
                    var left = ($window.width() - $this.outerWidth())/2+$window.scrollLeft();
                    $this.css('left',left)
                }
                if (!y == false) {
            var top = ($window.height() - $this.outerHeight())/2+$window.scrollTop();   
                    $this.css('top',top);
                }
        // $(this).animate({
        //   top: (top > options.minY ? top : options.minY)+'px',
        //   left: (left > options.minX ? left : options.minX)+'px'
        // }, options.transition);
        return $(this);
      });
    }
  });
})(jQuery);

If I recall correctly, gcc determines the filetype from the suffix. So, make it foo.cc and it should work.

And, to answer your other question, that is the difference between "gcc" and "g++". gcc is a frontend that chooses the correct compiler.

You can create Activity and extends AppCompatActivity. Then in the Manifest put next style:

<activity android:name=".YourCustomDialog"
            android:theme="Theme.AppCompat.Light.Dialog">
</activity>

Inflate it by Buttons and TextViews

Then use this like a dialog.

For example, in the linearLayout I fill next parameters:

android:layout_width="300dp"
android:layout_height="wrap_content"

You might want to look into this C# function to escape the string:

http://www.aspcode.net/C-encode-a-string-for-JSON-JavaScript.aspx

public static string Enquote(string s)  
{ 
    if (s == null || s.Length == 0)  
    { 
        return "\"\""; 
    } 
    char         c; 
    int          i; 
    int          len = s.Length; 
    StringBuilder sb = new StringBuilder(len + 4); 
    string       t; 

    sb.Append('"'); 
    for (i = 0; i < len; i += 1)  
    { 
        c = s[i]; 
        if ((c == '\\') || (c == '"') || (c == '>')) 
        { 
            sb.Append('\\'); 
            sb.Append(c); 
        } 
        else if (c == '\b') 
            sb.Append("\\b"); 
        else if (c == '\t') 
            sb.Append("\\t"); 
        else if (c == '\n') 
            sb.Append("\\n"); 
        else if (c == '\f') 
            sb.Append("\\f"); 
        else if (c == '\r') 
            sb.Append("\\r"); 
        else 
        { 
            if (c < ' ')  
            { 
                //t = "000" + Integer.toHexString(c); 
                string t = new string(c,1); 
                t = "000" + int.Parse(tmp,System.Globalization.NumberStyles.HexNumber); 
                sb.Append("\\u" + t.Substring(t.Length - 4)); 
            }  
            else  
            { 
                sb.Append(c); 
            } 
        } 
    } 
    sb.Append('"'); 
    return sb.ToString(); 
} 

I dont exactly know what you want to do.But you cant send data of one form using a submit button of another form.

You could do one thing either use sessions or use hidden fields that has the submit button. You could use javascript/jquery to pass the values from the first form to the hidden fields of the second form.Then you could submit the form.

Or else the easiest you could do is use sessions.

<form>
<input type="text" class="input-text " value="" size="32" name="user_data[firstname]" id="elm_6">
<input type="text" class="input-text " value="" size="32" name="user_data[lastname]" id="elm_7">
</form>

<form action="#">
<input type="text" class="input-text " value="" size="32" name="user_data[b_firstname]" id="elm_14">
<input type="text" class="input-text " value="" size="32" name="user_data[s_firstname]" id="elm_16">

<input type="submit" value="Continue" name="dispatch[checkout.update_steps]">
</form>


$('input[type=submit]').click(function(){
$('#elm_14').val($('#elm_6').val());
$('#elm_16').val($('#elm_7').val());
});

This is the jsfiddle for it http://jsfiddle.net/FPsdy/102/

Some points to note when working with foreach():

a) foreach works on the prospected copy of the original array. It means foreach() will have SHARED data storage until or unless a prospected copy is not created foreach Notes/User comments.

b) What triggers a prospected copy? A prospected copy is created based on the policy of copy-on-write, that is, whenever an array passed to foreach() is changed, a clone of the original array is created.

c) The original array and foreach() iterator will have DISTINCT SENTINEL VARIABLES, that is, one for the original array and other for foreach; see the test code below. SPL , Iterators, and Array Iterator.

Stack Overflow question How to make sure the value is reset in a 'foreach' loop in PHP? addresses the cases (3,4,5) of your question.

The following example shows that each() and reset() DOES NOT affect SENTINEL variables (for example, the current index variable) of the foreach() iterator.

$array = array(1, 2, 3, 4, 5);

list($key2, $val2) = each($array);
echo "each() Original (outside): $key2 => $val2<br/>";

foreach($array as $key => $val){
    echo "foreach: $key => $val<br/>";

    list($key2,$val2) = each($array);
    echo "each() Original(inside): $key2 => $val2<br/>";

    echo "--------Iteration--------<br/>";
    if ($key == 3){
        echo "Resetting original array pointer<br/>";
        reset($array);
    }
}

list($key2, $val2) = each($array);
echo "each() Original (outside): $key2 => $val2<br/>";

Output:

each() Original (outside): 0 => 1
foreach: 0 => 1
each() Original(inside): 1 => 2
--------Iteration--------
foreach: 1 => 2
each() Original(inside): 2 => 3
--------Iteration--------
foreach: 2 => 3
each() Original(inside): 3 => 4
--------Iteration--------
foreach: 3 => 4
each() Original(inside): 4 => 5
--------Iteration--------
Resetting original array pointer
foreach: 4 => 5
each() Original(inside): 0=>1
--------Iteration--------
each() Original (outside): 1 => 2

If you are testing on localhost and you have no control of the response headers, you can disable it with a chrome flag.

Visit the url and disable it: chrome://flags/#same-site-by-default-cookies

I need to disable it because Chrome Canary just started enforcing this rule as of approximately V 82.0.4078.2 and now it's not setting these cookies.

Note: I only turn this flag on in Chrome Canary that I use for development. It's best not to turn the flag on for everyday Chrome browsing for the same reasons that google is introducing it.

Sure is:

@media screen and (-webkit-min-device-pixel-ratio:0)
{ 
    #element { properties:value; } 
}

And a little fiddle to see it in action - http://jsfiddle.net/Hey7J/

Must add tho... this is generally bad practice, you shouldn't really be at the point where you start to need individual browser hacks to make you CSS work. Try using reset style sheets at the start of your project, to help avoid this.

Also, these hacks may not be future proof.

Server-side, write:

if(IsPostBack)
{
   // NOTE: the following uses an overload of RegisterClientScriptBlock() 
   // that will surround our string with the needed script tags 
   ClientScript.RegisterClientScriptBlock(GetType(), "IsPostBack", "var isPostBack = true;", true);
}

Then, in your script which runs for the onLoad, check for the existence of that variable:

if(isPostBack) {
   // do your thing
}

You don't really need to set the variable otherwise, like Jonathan's solution. The client-side if statement will work fine because the "isPostBack" variable will be undefined, which evaluates as false in that if statement.

I have found a solution how to style just the component element. I have not found any documentation how it works, but you can put attributes values into the component directive, under the 'host' property like this:

@Component({
    ...
    styles: [`
      :host {
        'style': 'display: table; height: 100%',
        'class': 'myClass'
      }`
})
export class MyComponent
{
    constructor() {}

    // Also you can use @HostBinding decorator
    @HostBinding('style.background-color') public color: string = 'lime';
    @HostBinding('class.highlighted') public highlighted: boolean = true;
}

UPDATE: As Günter Zöchbauer mentioned, there was a bug, and now you can style the host element even in css file, like this:

:host{ ... }

his example will tell you how to pass input value to parent on submit button.

First define eventBus as new Vue.

//main.js
import Vue from 'vue';
export const eventBus = new Vue();

Pass your input value via Emit.
//Sender Page
import { eventBus } from "../main";
methods: {
//passing data via eventbus
    resetSegmentbtn: function(InputValue) {
        eventBus.$emit("resetAllSegment", InputValue);
    }
}

//Receiver Page
import { eventBus } from "../main";

created() {
     eventBus.$on("resetAllSegment", data => {
         console.log(data);//fetching data
    });
}

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

If you create a new database it's good to create user with permissions only for this database (if anything goes wrong you won't compromise root user login and password). So everything together will look like this:

mysql -u base_user -pbase_user_pass -e "create database new_db; GRANT ALL PRIVILEGES ON new_db.* TO new_db_user@localhost IDENTIFIED BY 'new_db_user_pass'"

Where:
base_user is the name for user with all privileges (probably the root)
base_user_pass it's the password for base_user (lack of space between -p and base_user_pass is important)
new_db is name for newly created database
new_db_user is name for the new user with access only for new_db
new_db_user_pass it's the password for new_db_user

Why can't you use it in MVC?

Rather than using the body load method use jQuery and wait for the the document onready function to complete.

When you are thinking of access modifiers just think of it in this way (applies to both variables and methods):

public --> accessible from every where
private --> accessible only within the same class where it is declared

Now the confusion arises when it comes to default and protected

default --> No access modifier keyword is present. This means it is available strictly within the package of the class. Nowhere outside that package it can be accessed.

protected --> Slightly less stricter than default and apart from the same package classes it can be accessed by sub classes outside the package it is declared.

Behaviour subjects. I wrote a blog about that.

import { BehaviorSubject } from 'rxjs/BehaviorSubject';
private noId = new BehaviorSubject<number>(0); 
  defaultId = this.noId.asObservable();

newId(urlId) {
 this.noId.next(urlId); 
 }

In this example i am declaring a noid behavior subject of type number. Also it is an observable. And if "something happend" this will change with the new(){} function.

So, in the sibling's components, one will call the function, to make the change, and the other one will be affected by that change, or vice-versa.

For example, I get the id from the URL and update the noid from the behavior subject.

public getId () {
  const id = +this.route.snapshot.paramMap.get('id'); 
  return id; 
}

ngOnInit(): void { 
 const id = +this.getId ();
 this.taskService.newId(id) 
}

And from the other side, I can ask if that ID is "what ever i want" and make a choice after that, in my case if i want to delte a task, and that task is the current url, it have to redirect me to the home:

delete(task: Task): void { 
  //we save the id , cuz after the delete function, we  gonna lose it 
  const oldId = task.id; 
  this.taskService.deleteTask(task) 
      .subscribe(task => { //we call the defaultId function from task.service.
        this.taskService.defaultId //here we are subscribed to the urlId, which give us the id from the view task 
                 .subscribe(urlId => {
            this.urlId = urlId ;
                  if (oldId == urlId ) { 
                // Location.call('/home'); 
                this.router.navigate(['/home']); 
              } 
          }) 
    }) 
}

For this , In C++ you can use itoa() function .This function convert any Decimal integer to binary, decimal , hexadecimal and octal number.

#include<bits/stdc++.h>
using namespace std;
int main(){
 int a;    
 char res[1000];
 cin>>a;
 itoa(a,res,10);
 cout<<"Decimal- "<<res<<endl;
 itoa(a,res,2);
 cout<<"Binary- "<<res<<endl;
 itoa(a,res,16);
 cout<<"Hexadecimal- "<<res<<endl;
 itoa(a,res,8);
 cout<<"Octal- "<<res<<endl;return 0;
}

However, it is only supported by specific compilers.

You can see also: itoa - C++ Reference

            if (header.getKey() == null || header.getKey().trim().isEmpty()) {
                continue;
            }
            if (header.getValue() == null || header.getValue().trim().isEmpty()) {
                builder.removeHeader(header.getKey());
            } else {
                builder.header(header.getKey(), header.getValue());
            }
        }
        return chain.proceed(builder.build());
    }

}

Example of usage:

httpClientBuilder.networkInterceptors().add(new RequestHeadersNetworkInterceptor(new HashMap<String, String>()
{
    {
        put("User-Agent", getUserAgent());
        put("Accept", "application/json");
    }
}));

Another way to reverse array

public static int []reversing(int[] array){
    int arraysize = array.length;
    int[] reverse = new int [arraysize+1];
    for(int i=1; i <= arraysize ; i++){
        int dec= arraysize -i;
        reverse[i] = array[dec];
    }
    return reverse;
}

"Book Author Title".parameterize('_').to_sym
=> :book_author_title

http://api.rubyonrails.org/classes/ActiveSupport/Inflector.html#method-i-parameterize

parameterize is a rails method, and it lets you choose what you want the separator to be. It is a dash "-" by default.

In addition to this, due to some recent website hacks we had to secure our sites more. In doing so, we discovered that file_get_contents failed to work, where curl still would work.

Not 100%, but I believe that this php.ini setting may have been blocking the file_get_contents request.

; Disable allow_url_fopen for security reasons
allow_url_fopen = 0

Either way, our code now works with curl.

These two tips can help you to decide whether to use a Map or an Object:

• Use maps over objects when keys are unknown until run time, and when all keys are the same type and all values are the same type.

• Use maps in case if there is a need to store primitive values as keys because object treats each key as a string either its a number value, boolean value or any other primitive value.

• Use objects when there is logic that operates on individual elements.

Alternatively, if using Sass, one can "extend" FA icons to display them:

.mytextwithicon:before {
  @extend .fas, .fa-angle-double-right;

  @extend .mr-2; // using bootstrap to add a small gap
                 // between the icon and the text.
}

The warning is due to you attempting to add an integer (int shift = 3) to a character value. You can change the data type to char if you want to avoid that.

A char is 16 bits, an int is 32.

char shift = 3;
// ...
eMessage[i] = (message[i] + shift) % (char)letters.length;

As an aside, you can simplify the following:

char[] message = {'o', 'n', 'c', 'e', 'u', 'p', 'o', 'n', 'a', 't', 'i', 'm', 'e'}; 

To:

char[] message = "onceuponatime".toCharArray();

As of .NET 4.6, there is DateTimeOffset.ToUnixTimeSeconds.

This is an instance method, so you are expected to call it on an instance of DateTimeOffset. You can also cast any instance of DateTime, though beware the timezone. To get the current timestamp:

DateTimeOffset.Now.ToUnixTimeSeconds()

To get the timestamp from a DateTime:

DateTime foo = DateTime.Now;
long unixTime = ((DateTimeOffset)foo).ToUnixTimeSeconds();

In Python 3, you can use

"one" in d.values()

to test if "one" is among the values of your dictionary.

In Python 2, it's more efficient to use

"one" in d.itervalues()

instead.

Note that this triggers a linear scan through the values of the dictionary, short-circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present.

how about something along these lines

<style type="text/css">
  #container {
    margin: 0 auto;
    text-align: center; /* for IE */
  }

  #yourdiv {
    width: 400px;
    border: 1px solid #000;
  }
</style>

....

<div id="container">
  <div id="yourdiv">
    weee
  </div>
</div>

You can also just open synaptic and search for libgtk, it will show you exactly which lib is installed.

Swift 3.0 in Xcode 8

Swift 3.0 has replaced many "stringly-typed" APIs with struct "wrapper types", as is the case with NotificationCenter. Notifications are now identified by a struct Notfication.Name rather than by String. See the Migrating to Swift 3 guide.

Previous usage:

// Define identifier
let notificationIdentifier: String = "NotificationIdentifier"

// Register to receive notification
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification(_:)), name: notificationIdentifier, object: nil)

// Post a notification
NSNotificationCenter.defaultCenter().postNotificationName(notificationIdentifier, object: nil)

New Swift 3.0 usage:

// Define identifier
let notificationName = Notification.Name("NotificationIdentifier")

// Register to receive notification
NotificationCenter.default.addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification), name: notificationName, object: nil)

// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)

All of the system notification types are now defined as static constants on Notification.Name; i.e. .UIDeviceBatteryLevelDidChange, .UIApplicationDidFinishLaunching, .UITextFieldTextDidChange, etc.

You can extend Notification.Name with your own custom notifications in order to stay consistent with the system notifications:

// Definition:
extension Notification.Name {
    static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}

// Usage:
NotificationCenter.default.post(name: .yourCustomNotificationName, object: nil)

Or use this code; ( same : new String[] )

.Split(new[] { "Test Test" }, StringSplitOptions.None)

Too late, just in case some one is looking for another way:

void Main()
{
    string jsonString = @"{
  'Stores': [
    'Lambton Quay',
    'Willis Street'
  ],
  'Manufacturers': [
    {
      'Name': 'Acme Co',
      'Products': [
        {
          'Name': 'Anvil',
          'Price': 50
        }
      ]
    },
    {
      'Name': 'Contoso',
      'Products': [
        {
          'Name': 'Elbow Grease',
          'Price': 99.95
        },
        {
          'Name': 'Headlight Fluid',
          'Price': 4
        }
      ]
    }
  ]
}";

    Product product = new Product();
    //Serializing to Object
    Product obj = JObject.Parse(jsonString).SelectToken("$.Manufacturers[?(@.Name == 'Acme Co' && @.Name != 'Contoso')]").ToObject<Product>();

    Console.WriteLine(obj);
}


public class Product
{
    public string Name { get; set; }
    public decimal Price { get; set; }
}

I also had the same issue, trying to run a unit test calling code that uses readEntity. Can't use getEntity in production code because that just returns a ByteInputStream and not the content of the body and there is no way I am adding production code that is hit only in unit tests.

My solution was to create a response and then use a Mockito spy to mock out the readEntity method:

Response error = Response.serverError().build();
Response mockResponse = spy(error);
doReturn("{jsonbody}").when(mockResponse).readEntity(String.class);

Note that you can't use the when(mockResponse.readEntity(String.class) option because that throws the same IllegalStateException.

Hope this helps!

Easy to explain:

Lets assume the following

URI is your Name

URL is your address with your name in-order to communicate with you.

• my name is Loyola

  Loyola is URI

• my address is TN, Chennai 600001.

TN, Chennai 600 001, Loyola is URL

Hope you understand,

Now lets see a precise example

http://www.google.com/fistpage.html

in the above you can communicate with a page called firstpage.html (URI) using following http://www.google.com/fistpage.html(URL).

Hence URI is subset of URL but not vice-versa.

Here's a workaround for installing the 64-bit version of the Microsoft Access Database Engine 2010 redistributable on a system with a 32-bit MS Office version installed:

• Check the 64-bit registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths" before installing the 64-bit version of the Microsoft Access Database Engine 2010 redistributable.
• If it does not contain the "mso.dll" registry value, then you will need to rename or delete the value after installing the 64-bit version of the Microsoft Access Database Engine 2010 redistributable on a system with a 32-bit version of MS Office installed.
• Use the "/passive" command line parameter to install the redistributable, e.g. "C:\directory path\AccessDatabaseEngine_x64.exe" /passive
• Delete or rename the "mso.dll" registry value, which contains the path to the 64-bit version of MSO.DLL (and should not be used by 32-bit MS Office versions).

Now you can start a 32-bit MS Office application without the "re-configuring" issue. Note that the "mso.dll" registry value will already be present if a 64-bit version of MS Office is installed. In this case the value should not be deleted or renamed.

Also if you do not want to use the "/passive" command line parameter you can edit the AceRedist.msi file to remove the MS Office architecture check:

• download and install Microsoft Orca: http://msdn.microsoft.com/en-us/library/windows/desktop/aa370557(v=vs.85).aspx
• unzip the AccessDatabaseEngine.exe or AccessDatabaseEngine_x64.exe file
• open the AceRedist.msi file in Orca
• search for two table rows containing the "CheckOfficeArchitecture" action and drop these rows
• save the updated AceRedist.msi file

You can now use this file to install the Microsoft Access Database Engine 2010 redistributable on a system where a "conflicting" version of MS Office is installed (e.g. 64-bit version on system with 32-bit MS Office version) Make sure that you rename the "mso.dll" registry value as explained above (if needed).

jQuery 3

As of jQuery 3, removeAttr does not set the corresponding property to false anymore:

Prior to jQuery 3.0, using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.

Changelog

Hence only .prop('checked',false) is correct way when using this version.

Original answer (from 2011):

For attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).

So, either will work... but the second example you gave (using prop) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr to do that.

A CRC is pretty simple; you take a polynomial represented as bits and the data, and divide the polynomial into the data (or you represent the data as a polynomial and do the same thing). The remainder, which is between 0 and the polynomial is the CRC. Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the algorithm.

The way to understand CRCs is to try to compute a few using a short piece of data (16 bits or so) with a short polynomial -- 4 bits, perhaps. If you practice this way, you'll really understand how you might go about coding it.

If you're doing it frequently, a CRC is quite slow to compute in software. Hardware computation is much more efficient, and requires just a few gates.

above mention, code works and my problem solved.

Wikipedia, of all places, actually discusses this.

The idea is to make sure all package names are unique world-wide, by having authors use a variant of a DNS name they own to name the package. For example, the owners of the domain name joda.org created a number of packages whose names begin with org.joda, for example:

• org.joda.time
• org.joda.time.base
• org.joda.time.chrono
• org.joda.time.convert
• org.joda.time.field
• org.joda.time.format

1. use .any()

   if numpy.isnan(myarray).any()

2. numpy.isfinite maybe better than isnan for checking

   if not np.isfinite(prop).all()

Internet Explorer (IE8 and lower) doesn't support addEventListener(...). It has its own event model using the attachEvent method. You could use some code like this:

var element = document.getElementById('container');
if (document.addEventListener){
    element .addEventListener('copy', beforeCopy, false); 
} else if (el.attachEvent){
    element .attachEvent('oncopy', beforeCopy);
}

Though I recommend avoiding writing your own event handling wrapper and instead use a JavaScript framework (such as jQuery, Dojo, MooTools, YUI, Prototype, etc) and avoid having to create the fix for this on your own.

By the way, the third argument in the W3C model of events has to do with the difference between bubbling and capturing events. In almost every situation you'll want to handle events as they bubble, not when they're captured. It is useful when using event delegation on things like "focus" events for text boxes, which don't bubble.

For python3.5, you can use the following code:

import urllib.request
res = urllib.request.urlopen(starturl)
finalurl = res.geturl()
print(finalurl)

<%= Html.TextBoxFor(model => model.EndDate, new { @class = "jquery_datepicker", @Value = Model.EndDate.ToString("dd.MM.yyyy") })%>

Some dtype are not supported by specific OpenCV functions. For example inputs of dtype np.uint32 create this error. Try to convert the input to a supported dtype (e.g. np.int32 or np.float32)

DC is your domain. If you want to connect to the domain example.com than your dc's are: DC=example,DC=com

You actually don't need any hostname or ip address of your domain controller (There could be plenty of them).

Just imagine that you're connecting to the domain itself. So for connecting to the domain example.com you can simply write

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");

And you're done.

You can also specify a user and a password used to connect:

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com", "username", "password");

Also be sure to always write LDAP in upper case. I had some trouble and strange exceptions until I read somewhere that I should try to write it in upper case and that solved my problems.

The directoryEntry.Path Property allows you to dive deeper into your domain. So if you want to search a user in a specific OU (Organizational Unit) you can set it there.

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
directoryEntry.Path = "LDAP://OU=Specific Users,OU=All Users,OU=Users,DC=example,DC=com";

This would match the following AD hierarchy:

• com
  • example
    • Users
      • All Users
        • Specific Users

Simply write the hierarchy from deepest to highest.

Now you can do plenty of things

For example search a user by account name and get the user's surname:

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
DirectorySearcher searcher = new DirectorySearcher(directoryEntry) {
    PageSize = int.MaxValue,
    Filter = "(&(objectCategory=person)(objectClass=user)(sAMAccountName=AnAccountName))"
};

searcher.PropertiesToLoad.Add("sn");

var result = searcher.FindOne();

if (result == null) {
    return; // Or whatever you need to do in this case
}

string surname;

if (result.Properties.Contains("sn")) {
    surname = result.Properties["sn"][0].ToString();
}

If you need to initialize an array fast, you might do it by blocks instead of with a generator initializer, and it's going to be much faster. Creating a list by [0]*count is just as fast, still.

import array

def zerofill(arr, count):
    count *= arr.itemsize
    blocksize = 1024
    blocks, rest = divmod(count, blocksize)
    for _ in xrange(blocks):
        arr.fromstring("\x00"*blocksize)
    arr.fromstring("\x00"*rest)

def test_zerofill(count):
    iarr = array.array('i')
    zerofill(iarr, count)
    assert len(iarr) == count

def test_generator(count):
    iarr = array.array('i', (0 for _ in xrange(count)))
    assert len(iarr) == count

def test_list(count):
    L = [0]*count
    assert len(L) == count

if __name__ == '__main__':
    import timeit
    c = 100000
    n = 10
    print timeit.Timer("test(c)", "from __main__ import c, test_zerofill as test").repeat(number=n)
    print timeit.Timer("test(c)", "from __main__ import c, test_generator as test").repeat(number=n)
    print timeit.Timer("test(c)", "from __main__ import c, test_list as test").repeat(number=n)

Results:

(array in blocks) [0.022809982299804688, 0.014942169189453125, 0.014089107513427734]

  <%= label :contactmethod_sms, 'SMS' %>
<% end %>

Another possible cause is that your architecture is not supported. I ran into this because I was provided with a CentOS VM, wanted to install EPEL and couldn't for the life of me get it done.

Turns out the VM was CentOS 7 i386, which is an architecture that is apparently no longer supported by EPEL. I guess the only remedy in this case is to reinstall.

in laravel 5 first we need to create migration and then run the migration

Step 1.

php artisan make:migration create_users_table --create=users

Step 2.

php artisan migrate

I'll post my solution as it it subtly different from others and also took me a solid day to get right, with the assistance of the existing answers.

For a multi-module Maven project:

ROOT
|--WAR
|--LIB-1
|--LIB-2
|--TEST

Where the WAR project is the main web app, LIB 1 and 2 are additional modules the WAR depends on and TEST is where the integration tests live. TEST spins up an embedded Tomcat instance (not via Tomcat plugin) and runs WAR project and tests them via a set of JUnit tests. The WAR and LIB projects both have their own unit tests.

The result of all this is the integration and unit test coverage being separated and able to be distinguished in SonarQube.

I got same error after publish my project to my physical server. My web application works perfectly on my computer when I compile on VS2013. When I checked connection string on sql server manager, everything works perfect on server too. I also checked firewall (I switched it off). But still didn't work. I remotely try to connect database by SQL Manager with exactly same user/pass and instance name etc with protocol pipe/tcp and I saw that everything working normally. But when I try to open website I'm getting this error. Is there anyone know 4th option for fix this problem?.

NOTE: My App: ASP.NET 4.5 (by VS2013), Server: Windows 2008 R2 64bit, SQL: MS-SQL WEB 2012 SP1 Also other web applications works great at web browsers with their database on same server.

After one day suffering I found the solution of my issue:

First I checked all the logs and other details but i could find nothing. Suddenly I recognize that; when I try to use connection string which is connecting directly to published DB and run application on my computer by VS2013, I saw that it's connecting another database file. I checked local directories and I found it. ASP.NET Identity not using my connection string as I wrote in web.config file. And because of this VS2013 is creating or connecting a new database with the name "DefaultConnection.mdf" in App_Data folder. Then I found the solution, it was in IdentityModel.cs.

I changed code as this:

public class ApplicationUser : IdentityUser
{
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    //public ApplicationDbContext() : base("DefaultConnection") ---> this was original
    public ApplicationDbContext() : base("<myConnectionStringNameInWebConfigFile>") //--> changed
    {
    }
}

So, after all, I re-builded and published my project and everything works fine now :)

I've had issues with using SELECT last_insert_rowid() in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.

Here's where they state that in the doco:

If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.

That's from sqlite.org doco

@jk1 answer is perfect, since @igor Ganapolsky asked, why can't we use Mockito.mock here? i post this answer.

For that we have provide one setter method for myobj and set the myobj value with mocked object.

class MyClass {
    MyInterface myObj;

    public void abc() {
        myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }

    public void setMyObj(MyInterface obj)
    {
        this.myObj=obj;
    }
}

In our Test class, we have to write below code

class MyClassTest {

MyClass myClass = new MyClass();

    @Mock
    MyInterface myInterface;

I just wanted to add a solution for Mac users since this is the top article that comes up for searches related to this issue. If you have macOS 10.13 or later you can make use of APFS Space Sharing.

• Open Disk Utility
• Click Partition
• Click Add Volume -- no need to Partition as we are adding an APFS volume which shares space within the current partition/container)
• Give the volume a name (without spaces)
• Click Add
• You can now mount this drive like any other via Terminal: cd /Volumes/<your_volume_name>
• Create an empty folder in the new volume -- I called mine sdk
• You can now select the volume and directory while installing Android Studio

Is there maybe a way to grab the rendered page from the internet explorer rendering engine and send it to a PDF-Printer tool automatically?

This is how ActivePDF works, which is good means that you know what you'll get, and it actually has reasonable styling support.

It is also one of the few packages I found (when looking a few years back) that actually supports the various page-break CSS commands.

Unfortunately, the ActivePDF software is very frustrating - since it has to launch the IE browser in the background for conversions it can be quite slow, and it is not particularly stable either.

There is a new version currently in Beta which is supposed to be much better, but I've not actually had a chance to try it out, so don't know how much of an improvement it is.

If you also want to match newlines, then you might want to use "^[\s\S]{1,35}$" (depending on the regex engine). Otherwise, as others have said, you should used "^.{1,35}$"

To enable/disable draggable in jQuery I used:

$("#draggable").draggable({ disabled: true });          

$("#draggable").draggable({ disabled: false });

@Calciphus answer didn't work for me with the opacity problem, so I used:

div.ui-state-disabled.ui-draggable-disabled {opacity: 1;}

Worked on mobile devices either.

Here is the code: http://jsfiddle.net/nn5aL/1/

How about

sudo yum install php-mysql

or

sudo apt-get install php5-mysql

As some said basename($_SERVER["SCRIPT_FILENAME"], '.php') and basename( __FILE__, '.php') are good ways to test this.

To me using the second was the solution for some validation instructions I was making

Correct me if I am wrong, but getClass() will be useful when you want to make sure your instance is NOT a subclass of the class you are comparing with. If you use instanceof in that situation you can NOT know that because:

class A { }

class B extends A { }

Object oA = new A();
Object oB = new B();

oA instanceof A => true
oA instanceof B => false
oB instanceof A => true // <================ HERE
oB instanceof B => true

oA.getClass().equals(A.class) => true
oA.getClass().equals(B.class) => false
oB.getClass().equals(A.class) => false // <===============HERE
oB.getClass().equals(B.class) => true

I was having a similar problem. PHP was working on my sites configured by virtualmin but not for phpmyadmin. PHPMyAdmin would not execute and the file was being downloaded by the browser. Everything I was reading was saying that libapache2-mod-php5 was not installed but I knew it was... so the thing to do was to purge it and reinstall.

sudo apt-get purge libapache2-mod-php5

sudo apt-get install libapache2-mod-php5

sudo apt-get purge phpmyadmin

sudo apt-get install phpmyadmin

sudo /etc/init.d/apache2 restart

If you disable the button, then its name=value pair will indeed not be sent as parameter. But the remnant of the parameters should be sent (as long as their respective input elements and the parent form are not disabled). Likely you're testing the button only or the other input fields or even the form are disabled?

REASON WHY THIS HAPPENS (EXPLANATION)

suppose we have 2 tables users and subscription.

1 user has 1 subscription

IN USER MODEL, we have

public function subscription()
{
    return $this->hasOne('App\Subscription','user_id');
}

we can access subscription details as follows

$users = User:all();

foreach($users as $user){
    echo $user->subscription;
}

if any of the user does not have a subscription, which can be a case. we cannot use arrow function further after subscription like below

$user->subscription->abc   [this will not work] 
$user->subscription['abc']  [this will work]

but if the user has a subscription

$user->subscription->abc   [this will work] 

NOTE: try putting a if condition like this

if($user->subscription){
 return $user->subscription->abc;
}

Do you want the JDK or the JRE? Anyways, I had this problem too, a few weeks ago. I followed the instructions here and it worked:

http://www.backtrack-linux.org/wiki/index.php/Java_Install

NOTE: Before installing Java make sure you kill Firefox.

root@bt:~# killall -9 /opt/firefox/firefox-bin

You can download java from the official website. (Download tar.gz version)

We first create the directory and place java there:

root@bt:~# mkdir /opt/java

root@bt:~# mv -f jre1.7.0_05/ /opt/java/

Final changes.

root@bt:~# update-alternatives --install /usr/bin/java java /opt/java/jre1.7.0_05/bin/java 1

root@bt:~# update-alternatives --set java /opt/java/jre1.7.0_05/bin/java

root@bt:~# export JAVA_HOME="/opt/java/jre1.7.0_05"

Adding the plugin to Firefox.

For Java 7 (32 bit)

root@bt:~# ln -sf $JAVA_HOME/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

For Java 8 (64 bit)

root@bt:~# ln -sf $JAVA_HOME/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/

Testing the plugin.

root@bt:~# firefox http://java.com/en/download/testjava.jsp

Try if this works:

Panel2.Style.Add("display", "none");

Java 1.8 (as well as Groovy and Scala) has a thing called "Interface Defender Methods", which are interfaces with pre-defined default method bodies. By implementing multiple interfaces that use defender methods, you could effectively, in a way, extend the behavior of two interface objects.

Also, in Groovy, using the @Delegate annotation, you can extend behavior of two or more classes (with caveats when those classes contain methods of the same name). This code proves it:

class Photo {
    int width
    int height
}    
class Selection {
    @Delegate Photo photo    
    String title
    String caption
}    
def photo = new Photo(width: 640, height: 480)
def selection = new Selection(title: "Groovy", caption: "Groovy", photo: photo)
assert selection.title == "Groovy"
assert selection.caption == "Groovy"    
assert selection.width == 640
assert selection.height == 480

The traceback module provides methods for formatting and printing exceptions and their tracebacks, e.g. this would print exception like the default handler does:

import traceback

try:
    1/0
except Exception:
    traceback.print_exc()

Output:

Traceback (most recent call last):
  File "C:\scripts\divide_by_zero.py", line 4, in <module>
    1/0
ZeroDivisionError: division by zero

You can use the selected attribute for the option element to select a choice by default. You can use the required attribute for the select element to ensure that the user selects something.

In Javascript, you can check the selectedIndex property to get the index of the selected option, or you can check the value property to get the value of the selected option.

According to the HTML5 spec, selectedIndex "returns the index of the first selected item, if any, or -1 if there is no selected item. And value "returns the value of the first selected item, if any, or the empty string if there is no selected item." So if selectedIndex = -1, then you know they haven't selected anything.

<button type="button" onclick="displaySelection()">What did I pick?</button>
<script>
    function displaySelection()
    {
        var mySelect = document.getElementById("someSelectElement");
        var mySelection = mySelect.selectedIndex;
        alert(mySelection);
    }
</script>

All of the answers so far involve completely replacing the default button behavior with something else. However, IMHO it is useful and important to understand that it's possible to change just the part you care about, by editing the existing, default template for a XAML element.

In the case of dealing with the hover effect on a WPF button, the change in appearance in a WPF Button element is caused by a Trigger in the default style for the Button, which is based on the IsMouseOver property and sets the Background and BorderBrush properties of the top-level Border element in the control template. The Button element's background is underneath the Border element's background, so changing the Button.Background property doesn't prevent the hover effect from being seen.

With some effort, you could override this behavior with your own setter, but because the element you need to affect is in the template and not directly accessible in your own XAML, that approach would be difficult and IMHO overly complex.

Another option would be to make use the graphic as the Content for the Button rather than the Background. If you need additional content over the graphic, you can combine them with a Grid as the top-level object in the content.

However, if you literally just want to disable the hover effect entirely (rather than just hiding it), you can use the Visual Studio XAML Designer:

1. While editing your XAML, select the "Design" tab.
2. In the "Design" tab, find the button for which you want to disable the effect.
3. Right-click that button, and choose "Edit Template/Edit a Copy...". Select in the prompt you get where you want the new template resource to be placed. This will appear to do nothing, but in fact the Designer will have added new resources where you told it, and changed your button element to reference the style that uses those resources as the button template.
4. Now, you can go edit that style. The easiest thing is to delete or comment-out (e.g. Ctrl+E, C) the <Trigger Property="IsMouseOver" Value="true">...</Trigger> element. Of course, you can make any change to the template you want at that point.

When you're done, the button style will look something like this:

<p:Style x:Key="FocusVisual">
  <Setter Property="Control.Template">
    <Setter.Value>
      <ControlTemplate>
        <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>

        </Border>
        <ControlTemplate.Triggers>

            <Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
          </Trigger>
          <!--<Trigger Property="IsMouseOver" Value="true">

            <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
          </Trigger>-->
          <Trigger Property="IsPressed" Value="true">
            <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
            <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
          </Trigger>
          <Trigger Property="IsEnabled" Value="false">

            <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
            <Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</p:Style>

(Note: you can omit the p: XML namespace qualifications in the actual code…I provide them here only because the Stack Overflow XML code formatter gets confused by <Style/> elements that don't have a fully-qualified name with XML namespace.)

If you want to apply the same style to other buttons, you can just right-click them and choose "Edit Template/Apply Resource" and select the style you just added for the first button. You can even make that style the default style for all buttons, using the normal techniques for applying a default style to elements in XAML.

If all else fails, you can always submit a query, limiting the return rows to none:

select * from MYTABLENAME limit 0

bool? a = null;
bool b = Convert.toBoolean(a); 

I made a small variation to include all tables, also for non-public tables.

CREATE TYPE table_count AS (table_schema TEXT,table_name TEXT, num_rows INTEGER); 

CREATE OR REPLACE FUNCTION count_em_all () RETURNS SETOF table_count  AS '
DECLARE 
    the_count RECORD; 
    t_name RECORD; 
    r table_count%ROWTYPE; 

BEGIN
    FOR t_name IN 
        SELECT table_schema,table_name
        FROM information_schema.tables
        where table_schema !=''pg_catalog''
          and table_schema !=''information_schema''
        ORDER BY 1,2
        LOOP
            FOR the_count IN EXECUTE ''SELECT COUNT(*) AS "count" FROM '' || t_name.table_schema||''.''||t_name.table_name
            LOOP 
            END LOOP; 

            r.table_schema := t_name.table_schema;
            r.table_name := t_name.table_name; 
            r.num_rows := the_count.count; 
            RETURN NEXT r; 
        END LOOP; 
        RETURN; 
END;
' LANGUAGE plpgsql; 

use select count_em_all(); to call it.

Hope you find this usefull. Paul

It is better to use an HTML character

{{ entity.text[:50] }}…

It's already 2019, I can't believe still no easiest and conveniencest way to convert the most popular Micro$oft Word document to Adobe PDF format in Java world.

I almost tried every method the above answers mentioned, and I found the best and the only way can satisfy my requirement is by using OpenOffice or LibreOffice. Actually I am not exactly know the difference between them, seems both of them provide soffice command line.

My requirement is:

1. It must run on Linux, more specifically CentOS, not on Windows, thus we cannot install Microsoft Office on it;
2. It must support Chinese character, so ISO-8859-1 character encoding is not a choice, it must support Unicode.

First thing came in mind is doc-to-pdf-converter, but it lacks of maintenance, last update happened 4 years ago, I will not use a nobody-maintain-solution. Xdocreport seems a promising choice, but it can only convert docx, but not doc binary file which is mandatory for me. Using Java to call OpenOffice API seems good, but too complicated for such a simple requirement.

Finally I found the best solution: use OpenOffice command line to finish the job:

Runtime.getRuntime().exec("soffice --convert-to pdf -outdir . /path/some.doc");

I always believe the shortest code is the best code (of course it should be understandable), that's it.

From http://docs.python.org/library/csv.html#csv.writer:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

In other words, when opening the file you pass 'wb' as opposed to 'w'.
You can also use a with statement to close the file when you're done writing to it.
Tested example below:

from __future__ import with_statement # not necessary in newer versions
import csv
headers=['id', 'year', 'activity', 'lineitem', 'datum']
with open('file3.csv','wb') as fou: # note: 'wb' instead of 'w'
    output = csv.DictWriter(fou,delimiter=',',fieldnames=headers)
    output.writerow(dict((fn,fn) for fn in headers))
    output.writerows(rows)

You could use AJAX to send a POST request if you don't want forms.

Using jquery $.post method it is pretty simple:

$.post('/foo.php', { key1: 'value1', key2: 'value2' }, function(result) {
    alert('successfully posted key1=value1&key2=value2 to foo.php');
});

Encountered this error while using maven-shade-plugin, the solution was including:

META-INF/spring.schemas

and

Another thing which worked was -

1. Manually delete & then Create a designer file in filesystem.
2. Edit Project file.
3. Add code to include designer
   Eg: <Compile Include="<Path>\FileName.ascx.designer.cs"> <DependentUpon>FileName.ascx</DependentUpon> </Compile>
4. Reload Project
5. Open as(c/p)x file in design/view mode & save it.
6. Check designer file. Code will be there.

<script type="text/javascript">
     function SelectAnimal(){
         //Set selected option of Animals based on AnimalToFind value...
         var animalTofind = document.getElementById('AnimalToFind');
         var selection = document.getElementById('Animals');

        // select element
        for(var i=0;i<selection.options.length;i++){
            if (selection.options[i].innerHTML == animalTofind.value) {
                selection.selectedIndex = i;
                break;
            }
        }
     }
</script>

setting the selectedIndex property of the select tag will choose the correct item. it is a good idea of instead of comparing the two values (options innerHTML && animal value) you can use the indexOf() method or regular expression to select the correct option despite casing or presense of spaces

selection.options[i].innerHTML.indexOf(animalTofind.value) != -1;

or using .match(/regular expression/)

<?php echo substr("abcabcabc", 0, -3); ?>

I was missing this authenticator object argument in the below line

Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

This line solved my problem now I can send mail through my Java application. Rest of the code is simple just like above.

The underlying MD5 algorithm is no longer deemed secure, thus while md5sum is well-suited for identifying known files in situations that are not security related, it should not be relied on if there is a chance that files have been purposefully and maliciously tampered. In the latter case, the use of a newer hashing tool such as sha256sum is highly recommended.

So, if you are simply looking to check for file corruption or file differences, when the source of the file is trusted, MD5 should be sufficient. If you are looking to verify the integrity of a file coming from an untrusted source, or over from a trusted source over an unencrypted connection, MD5 is not sufficient.

Another commenter noted that Ubuntu and others use MD5 checksums. Ubuntu has moved to PGP and SHA256, in addition to MD5, but the documentation of the stronger verification strategies are more difficult to find. See the HowToSHA256SUM page for more details.

You can do something like this:

 (SELECT
    name, games, goals
    FROM tblMadrid WHERE name = 'ronaldo')
 UNION
 (SELECT
    name, games, goals
    FROM tblBarcelona WHERE name = 'messi')
ORDER BY goals;

See, for example: https://dev.mysql.com/doc/refman/5.0/en/union.html

No, its easy to do this. In Xcode, set the Active Configuration to Release. Change the device from Simulator to Device - whatever SDK. If you want to directly export to your iPhone, connect it to your computer. Press Build and Go. If your iPhone is not connected to your computer, a message will come up saying that your iPhone is not connected.

If this applies to you: (iPhone was not connected)

Go to your projects folder and then to the build folder inside. Go to the Release-iphoneos folder and take the app inside, drag and drop on iTunes icon. When you sync your iTouch device, it will copy it to your device. It will also show up in iTunes as a application for the iPhone.

Hope this helps!

P.S.: If it says something about a certificate not being valid, just click on the project in Xcode, the little project icon in the file stack to the left, and press Apple+I, or do Get Info from the menu bar. Click on Build at the top. Under Code Signing, change Code Signing Identity - Any iPhone OS Device to be Don't Sign.
