The solution is this:

  <input (click)="focusOut()" type="text" matInput [formControl]="inputControl"
  [matAutocomplete]="auto">
   <mat-autocomplete #auto="matAutocomplete" [displayWith]="displayFn" >
     <mat-option (onSelectionChange)="submitValue($event)" *ngFor="let option of 
      options | async" [value]="option">
      {{option.name | translate}}
     </mat-option>
  </mat-autocomplete>

TS
focusOut() {
this.inputControl.disable();
this.inputControl.enable();
}

Actually, in iOS development by react-native when I use display: 'none' or something like below:

const styles = StyleSheet.create({
  disappearImage: {
    width: 0,
    height: 0
  }
});

The iOS doesn't load anything else of the Image component like onLoad or etc, so I decided to use something like below:

const styles = StyleSheet.create({
  disappearImage: {
    width: 1,
    height: 1,
    position: 'absolute',
    top: -9000,
    opacity: 0
  }
});

This validates dd/mm/yyy dates. Edit your jquery.validate.js and add these.

Reference(Regex): Regex to validate date format dd/mm/yyyy

dateBR: function( value, element ) {
    return this.optional(element) || /^(?:(?:31(\/|-|\.)(?:0?[13578]|1[02]))\1|(?:(?:29|30)(\/|-|\.)(?:0?[1,3-9]|1[0-2])\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:29(\/|-|\.)0?2\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\d|2[0-8])(\/|-|\.)(?:(?:0?[1-9])|(?:1[0-2]))\4(?:(?:1[6-9]|[2-9]\d)?\d{2})$/.test(value);
}

messages: {
    dateBR: "Invalid date."
}

classRuleSettings: {
    dateBR: {dateBR: true}
}

Usage:

$( "#myForm" ).validate({
    rules: {
        field: {
            dateBR: true
        }
    }

Removing the outline is an accessibility nightmare. People tabbing using keyboards will never know what item they're on.

Best to leave it, as most clicked buttons will take you somewhere anyway, or if you HAVE to remove the outline then isolate it a specific class name.

.no-outline {
  outline: none;
}

Then you can apply that class whenever you need to.

<input type="text" name="name" id="event" onkeydown="return alphaOnly(event);"   required />


function alphaOnly(event) {
  var key = event.keyCode;`enter code here`
  return ((key >= 65 && key <= 90) || key == 8);
};

This may be what you want:

Working jsFiddle here

• This code places a default text string Enter your name here inside the <input> textbox, and colorizes the text to light grey.

• As soon as the box is clicked, the default text is cleared and text color set to black.

• If text is erased, the default text string is replaced and light grey color reset.

HTML:

<input id="fname" type="text" />

jQuery/javascript:

$(document).ready(function() {

    var curval;
    var fn = $('#fname');
    fn.val('Enter your name here').css({"color":"lightgrey"});

    fn.focus(function() {
        //Upon ENTERING the field
        curval = $(this).val();
        if (curval == 'Enter your name here' || curval == '') {
            $(this).val('');
            $(this).css({"color":"black"});
        }
    }); //END focus()

    fn.blur(function() {
        //Upon LEAVING the field
        curval = $(this).val();
        if (curval != 'Enter your name here' && curval != '') {
            $(this).css({"color":"black"});
        }else{
            fn.val('Enter your name here').css({"color":"lightgrey"});
        }
    }); //END blur()

}); //END document.ready

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:

<script type="text/javascript">
$(function() {
  $('form').submit(function(){
    $.post('http://example.com/upload', function() {
      window.location = 'http://google.com';
    });
    return false;
  });
});
</script>

you can use attribute placeholder

<input type="text" name="email" placeholder="[email protected]" size="30" />

or try this for older browsers

<input type="text" name="email" value="[email protected]" size="30" onblur="if(this.value==''){this.value='[email protected]';}" onfocus="if(this.value=='[email protected]'){this.value='';}">

you need to include the Wordpress loop in your search.php this is example

search.php template file:

<?php get_header(); ?>
<?php
$s=get_search_query();
$args = array(
                's' =>$s
            );
    // The Query
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) {
        _e("<h2 style='font-weight:bold;color:#000'>Search Results for: ".get_query_var('s')."</h2>");
        while ( $the_query->have_posts() ) {
           $the_query->the_post();
                 ?>
                    <li>
                        <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
                    </li>
                 <?php
        }
    }else{
?>
        <h2 style='font-weight:bold;color:#000'>Nothing Found</h2>
        <div class="alert alert-info">
          <p>Sorry, but nothing matched your search criteria. Please try again with some different keywords.</p>
        </div>
<?php } ?>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

For Xamarin.Android I have created this extension.

public static class ViewExtensions
{
    public static void FocusEditText(this EditText editText, Activity activity)
    {
        if (editText.RequestFocus())
        {
            InputMethodManager imm = (InputMethodManager)activity.GetSystemService(Context.InputMethodService);
            imm.ShowSoftInput(editText, ShowFlags.Implicit);
        }
    }
}

You may use this..

<body>
    <form method="" action="">
        <input type="text" name="email" class="input" />
        <input type="submit" value="Sign Up" class="button" />
    </form>
</body>

<script>
    $(document).ready(function() {
        $(".input").val("Email Address");
        $(".input").on("focus", function() {
            $(".input").val("");
        });
        $(".button").on("click", function(event) {
            $(".input").val("");
        });
    });
</script>

Talking of your own code, the problem is that the attr api of jquery is set by

$('.input').attr('value','Email Adress');

and not as you have done:

$('.input').attr('value') = 'Email address';

Using Java 8 lambda expression:

editText.setOnFocusChangeListener((v, hasFocus) -> {
    if(!hasFocus) {
        String value = String.valueOf( editText.getText() );
    }        
});

Use the following code, write it under onCreate()

InputMethodManager inputManager = (InputMethodManager)
                                   getSystemService(Context.INPUT_METHOD_SERVICE); 
inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),
                                   InputMethodManager.HIDE_NOT_ALWAYS);         
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

Surprising to see nobody mentioned document.hasFocus

if (document.hasFocus()) console.log('Tab is active')

MDN has more information.

It seems that you can check the tabIndex property of an element to determine if it is focusable. An element that is not focusable has a tabindex of "-1".

Then you just need to know the rules for tab stops:

• tabIndex="1" has the highest priorty.
• tabIndex="2" has the next highest priority.
• tabIndex="3" is next, and so on.
• tabIndex="0" (or tabbable by default) has the lowest priority.
• tabIndex="-1" (or not tabbable by default) does not act as a tab stop.
• For two elements that have the same tabIndex, the one that appears first in the DOM has the higher priority.

Here is an example of how to build the list of tab stops, in sequence, using pure Javascript:

function getTabStops(o, a, el) {
    // Check if this element is a tab stop
    if (el.tabIndex > 0) {
        if (o[el.tabIndex]) {
            o[el.tabIndex].push(el);
        } else {
            o[el.tabIndex] = [el];
        }
    } else if (el.tabIndex === 0) {
        // Tab index "0" comes last so we accumulate it seperately
        a.push(el);
    }
    // Check if children are tab stops
    for (var i = 0, l = el.children.length; i < l; i++) {
        getTabStops(o, a, el.children[i]);
    }
}

var o = [],
    a = [],
    stops = [],
    active = document.activeElement;

getTabStops(o, a, document.body);

// Use simple loops for maximum browser support
for (var i = 0, l = o.length; i < l; i++) {
    if (o[i]) {
        for (var j = 0, m = o[i].length; j < m; j++) {
            stops.push(o[i][j]);
        }
    }
}
for (var i = 0, l = a.length; i < l; i++) {
    stops.push(a[i]);
}

We first walk the DOM, collecting up all tab stops in sequence with their index. We then assemble the final list. Notice that we add the items with tabIndex="0" at the very end of the list, after the items with a tabIndex of 1, 2, 3, etc.

For a fully working example, where you can tab around using the "enter" key, check out this fiddle.

You can add color in the style rule of your input: color:#ccc;

For the Submit button, add this code and then set your form target="newwin"

onclick=window.open("about:blank","newwin") 

you can try this HTML

<input id="pan" onkeyup="inUpper()" />

javaScript

function _( x ) {
  return document.getElementById( x );
}
  // convert text in upper case
  function inUpper() {
    _('pan').value = _('pan').value.toUpperCase();
  }

It doesn't work because you are using fill_parent as the width. The weight is used to distribute the remaining empty space or take away space when the total sum is larger than the LinearLayout. Set your widths to 0dip instead and it will work.

Quick fix:

position: relative;
top: -12px;
left: -2px;

this should balance out those offsets, but maybe you should take a look at your whole layout and see how that box interacts with other boxes.

As for terminology, left, right, top and bottom are CSS offset properties. They are used for positioning elements at a specific location (when used with absolute or fixed positioning), or to move them relative to their default location (when used with relative positioning). Margins on the other hand specify gaps between boxes and they sometimes collapse, so they can't be reliably used as offsets.

But note that in your case that offset may not be computed (solely) from CSS offsets.

Have you tried using an iFrame? No ajax, and the original page will not load.

You can display the submit form as a separate page inside the iframe, and when it gets submitted the outer/container page will not reload. This solution will not make use of any kind of ajax.

If you want nice validation popups and images when an error occurs you can use the setError method of the EditText class as I describe here

Suppose access a proxy server A(eg. nginx), and the server A forwards the request to another server B(eg. tomcat).

If this process continues for a long time (more than the proxy server read timeout setting), A still did not get a completed response of B. It happens.

for nginx, You can configure the proxy_read_timeout(in location) property to solve his.But this is usually not a good idea, if you set the value too high. This may hide the real error.You'd better improve the design to really solve this problem.

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //

    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

Install a JDK.

It's possible to get Eclipse to run with a JRE, or at least it used to be, but why bother? Eclipse is much happier with a JDK.

Remember that the JRE that is used to run Eclipse does not have to be the JRE that Eclipse uses to run an application.

PS. I'm assuming here that the original poster's problem was getting Eclipse to start, and not (as some other Answers seem to address) getting Eclipse to start an application.

You just use this: if not exist "C:\VTS\" mkdir C:\VTS it wll create a directory only if the folder does not exist.

Note that this existence test will return true only if VTS exists and is a directory. If it is not there, or is there as a file, the mkdir command will run, and should cause an error. You might want to check for whether VTS exists as a file as well.

The default Nginx directory on Debian is /var/www/nginx-default.

You can check the file: /etc/nginx/sites-enabled/default

and find

server {
        listen   80 default;

        access_log  /var/log/nginx/localhost.access.log;

Check out some of the answers to this question - I think it might apply to yours:

how to run click function after default behaviour of a element

I think you're running into an inconsistency in the browser implementation of the onclick function. Some choose to toggle the checkbox before the event is fired and some after.

And for all SQL Server versions

SELECT CAST(0.973684210526315789 * 100 AS DECIMAL(18, 2))

For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.

I found that setting the datasource to null removes the columns. This is what works for me:

c#:

VB:

Call CType(myDataGrid.DataSource, DataTable).Rows.Clear()

This should solve your problem, please feel free to offer fixes. This method will account also for daylight saving time for the given date.

  let utcDate = new Date(date.toLocaleString('en-US', { timeZone: "UTC" }));
  let tzDate = new Date(date.toLocaleString('en-US', { timeZone: timeZone }));
  let offset = utcDate.getTime() - tzDate.getTime();

  date.setTime( date.getTime() + offset );

  return date;

AFAIK, you don't need to map the UNC path to a drive letter in order to establish credentials for a server. I regularly used batch scripts like:

net use \\myserver /user:username password

:: do something with \\myserver\the\file\i\want.xml

net use /delete \\my.server.com

However, any program running on the same account as your program would still be able to access everything that username:password has access to. A possible solution could be to isolate your program in its own local user account (the UNC access is local to the account that called NET USE).

Note: Using SMB accross domains is not quite a good use of the technology, IMO. If security is that important, the fact that SMB lacks encryption is a bit of a damper all by itself.

in my case I have used - (Hyphen) in my script name in case of Jenkinsfile Library. Got resolved after replacing Hyphen(-) with Underscore(_)

The compareTo method is described as follows:

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Let's say we would like to compare Jedis by their age:

class Jedi implements Comparable<Jedi> {

    private final String name;
    private final int age;
        //...
}

Then if our Jedi is older than the provided one, you must return a positive, if they are the same age, you return 0, and if our Jedi is younger you return a negative.

public int compareTo(Jedi jedi){
    return this.age > jedi.age ? 1 : this.age < jedi.age ? -1 : 0;
}

By implementing the compareTo method (coming from the Comparable interface) your are defining what is called a natural order. All sorting methods in JDK will use this ordering by default.

There are ocassions in which you may want to base your comparision in other objects, and not on a primitive type. For instance, copare Jedis based on their names. In this case, if the objects being compared already implement Comparable then you can do the comparison using its compareTo method.

public int compareTo(Jedi jedi){
    return this.name.compareTo(jedi.getName());
}

It would be simpler in this case.

Now, if you inted to use both name and age as the comparison criteria then you have to decide your oder of comparison, what has precedence. For instance, if two Jedis are named the same, then you can use their age to decide which goes first and which goes second.

public int compareTo(Jedi jedi){
    int result = this.name.compareTo(jedi.getName());
    if(result == 0){
        result = this.age > jedi.age ? 1 : this.age < jedi.age ? -1 : 0;
    }
    return result;
}

If you had an array of Jedis

Jedi[] jediAcademy = {new Jedi("Obiwan",80), new Jedi("Anakin", 30), ..}

All you have to do is to ask to the class java.util.Arrays to use its sort method.

Arrays.sort(jediAcademy);

This Arrays.sort method will use your compareTo method to sort the objects one by one.

If you are in the folder which contains the file

git commit -m 'my notes' ./name_of_file.ext

You could probably use std::transform for that purpose. I would maybe prefer Neils version though, depending on what is more readable.

Example by xtofl (see comments):

#include <map>
#include <vector>
#include <algorithm>
#include <iostream>

template< typename tPair >
struct second_t {
    typename tPair::second_type operator()( const tPair& p ) const { return p.second; }
};

template< typename tMap > 
second_t< typename tMap::value_type > second( const tMap& m ) { return second_t< typename tMap::value_type >(); }


int main() {
    std::map<int,bool> m;
    m[0]=true;
    m[1]=false;
    //...
    std::vector<bool> v;
    std::transform( m.begin(), m.end(), std::back_inserter( v ), second(m) );
    std::transform( m.begin(), m.end(), std::ostream_iterator<bool>( std::cout, ";" ), second(m) );
}

Very generic, remember to give him credit if you find it useful.

In addition to the accepted answer. You can use a lambda instead of regex:

from bs4 import BeautifulSoup

html = """<p>test python</p>"""

soup = BeautifulSoup(html, "html.parser")

print(soup(text="python"))
print(soup(text=lambda t: "python" in t))

Output:

[]
['test python']

Create a new 640x480 image and fill it with purple (red+blue):

cv::Mat mat(480, 640, CV_8UC3, cv::Scalar(255,0,255));

Note:

• height before width
• type CV_8UC3 means 8-bit unsigned int, 3 channels
• colour format is BGR

Aggregate can also be used for same.

string[] test = new string[2];
test[0] = "Hello ";
test[1] = "World!";
string joinedString = test.Aggregate((prev, current) => prev + " " + current);

Try this one..

var listCheck = [];
console.log($("input[name='YourCheckBokName[]']"));
$("input[name='YourCheckBokName[]']:checked").each(function() {
     console.log($(this).val());
     listCheck .push($(this).val());
});
console.log(listCheck);

In python 2.6 the '%' operator performed a modulus. I don't think they changed it in 3.0.1

The modulo operator tells you the remainder of a division of two numbers.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

This is a bug in the Eclipse Android tools.

To fix: Right click on the project, go to Android tools -> Rename application package.

And also check AndroidManifest.xml if it updated correctly. In my case it didn't, and that should solve this problem.

Just turn off your WiFi in Mac OSX this works a treat!

When you create a thread, you need an instance of Runnable. The easiest way to pass in a parameter would be to pass it in as an argument to the constructor:

public class MyRunnable implements Runnable {

    private volatile String myParam;

    public MyRunnable(String myParam){
        this.myParam = myParam;
        ...
    }

    public void run(){
        // do something with myParam here
        ...
    }

}

MyRunnable myRunnable = new myRunnable("Hello World");
new Thread(myRunnable).start();

If you then want to change the parameter while the thread is running, you can simply add a setter method to your runnable class:

public void setMyParam(String value){
    this.myParam = value;
}

Once you have this, you can change the value of the parameter by calling like this:

myRunnable.setMyParam("Goodbye World");

Of course, if you want to trigger an action when the parameter is changed, you will have to use locks, which makes things considerably more complex.

I am pretty sure this is a duplicate. Anyway, have a look at the following piece of code

x <- seq(5, 15, length=1000)
y <- dnorm(x, mean=10, sd=3)
plot(x, y, type="l", lwd=1)

I'm sure you can work the rest out yourself, for the title you might want to look for something called main= and y-axis labels are also up to you.

If you want to see more of the tails of the distribution, why don't you try playing with the seq(5, 15, ) section? Finally, if you want to know more about what dnorm is doing I suggest you look here

Actually I used my script in html directly. But in javascript when you add oninput event listener for this event it gives the data automatically.You just need to assign the value as per your requirement.

another option would be to give the span display:table; and center it via margin:0 auto;

span {
display:table;
margin:0 auto;
}

Based on @Stoyan I came up with the following solution:

app.run(function($location, $anchorScroll){
    var uri = window.location.href;

    if(uri.length >= 4){

        var parts = uri.split('#!#');
        if(parts.length > 1){
            var anchor = parts[parts.length -1];
            $location.hash(anchor);
            $anchorScroll();
        }
    }
});

Use execfile for Python 2:

>>> execfile('C:\\test.py')

Use exec for Python 3

>>> exec(open("C:\\test.py").read())

A simple way is to check the version by typing psql --version in terminal

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

As nobody published a solution with CountDownLatch. What about:

public class Lockeable {
    private final CountDownLatch countDownLatch = new CountDownLatch(1);

    public void doAfterEvent(){
        countDownLatch.await();
        doSomething();
    }

    public void reportDetonatingEvent(){
        countDownLatch.countDown();
    }
}

The ES6 way of doing it would be by using template literals:

const str = `This 

is 

a

multiline text`; 

console.log(str);

More reference here

The same may be achieved with the stringi package:

library('stringi')
char_array <- c("foo_bar","bar_foo","apple","beer")
a <- data.frame("data"=char_array, "data2"=1:4)
(a$data <- stri_sub(a$data, 1, -4)) # from the first to the last but 4th char
## [1] "foo_" "bar_" "ap"   "b" 

String name = "Vikash";
String upperCase = name.toUpperCase();
String lowerCase = name.toLowerCase();

your panel class don't have a constructor that accepts a string

try change

RLS_strid_panel p = new RLS_strid_panel(namn1);

to

RLS_strid_panel p = new RLS_strid_panel();
p.setName1(name1);

Just uninstall whatever node version you have in your system. Then go to this site https://nodejs.org/download/release/ and choose your desired version like for me its like v7.0.0/ and click on that go get .msi file of that. Finally you will get installer in your system, so install it. It will solve all your problems.

When a JSON start's with {} it is a ObjectJSON object and when it start's with [] it is an Array JOSN Array

An JSON array can consist of a/many objects and that is called an array of objects

As Peter already pointed out:

In [1]: import requests

In [2]: r = requests.get('https://api.github.com/events')

In [3]: type(r)
Out[3]: requests.models.Response

In [4]: type(r.content)
Out[4]: str

You may also want to check r.text.

You can trigger the mouseLeave event whenever you touch an element on touchscreen. Here is a solution for all <a> tags:

function removeHover() {
    var anchors = document.getElementsByTagName('a');
    for(i=0; i<anchors.length; i++) {
        anchors[i].addEventListener('touchstart', function(e){
            $('a').mouseleave();
        }, false);
    }
}

If you have intl extension installed, you can use Transliterator::transliterate function to create a slug easily.

<?php
$string = 'Namnet på bildtävlingen';
$slug = \Transliterator::createFromRules(
    ':: Any-Latin;'
    . ':: NFD;'
    . ':: [:Nonspacing Mark:] Remove;'
    . ':: NFC;'
    . ':: [:Punctuation:] Remove;'
    . ':: Lower();'
    . '[:Separator:] > \'-\''
)
    ->transliterate( $string );
echo $slug; // namnet-pa-bildtavlingen
?>

Ubuntu/Debian distros have the start-stop-daemon tool which is for the same purpose you describe. See also /etc/init.d/skeleton to see how it is used in writing start/stop scripts.

Indeed, you can leave it empty (W3 validator doesn't complain).

Taking the idea one step further: leave out the ="". The advantage of this is that the link isn't treated as an anchor to the current page.

In addition to setting default_charset in php.ini, you can send the correct charset using header() from within your code, before any output:

header('Content-Type: text/html; charset=utf-8');

Working with Unicode in PHP is easy as long as you realize that most of the string functions don't work with Unicode, and some might mangle strings completely. PHP considers "characters" to be 1 byte long. Sometimes this is okay (for example, explode() only looks for a byte sequence and uses it as a separator -- so it doesn't matter what actual characters you look for). But other times, when the function is actually designed to work on characters, PHP has no idea that your text has multi-byte characters that are found with Unicode.

A good library to check into is phputf8. This rewrites all of the "bad" functions so you can safely work on UTF8 strings. There are extensions like the mbstring extension that try to do this for you, too, but I prefer using the library because it's more portable (but I write mass-market products, so that's important for me). But phputf8 can use mbstring behind the scenes, anyway, to increase performance.

I use that for all status (update, insert and delete)

Try removing all previous architectures (i.e. remove the ARCHS_STANDARD setting) at the same time as you add i386 to the Architectures. This should change the active architecture to i386. I encountered a similar issue when I tried to build for armv7 by default, but it kept trying to build for arm64. I changed ARCHS_STANDARD to ARCHS_STANDARD_32_BIT, and this changed the active architecture chosen.

Remember that HTML and XML are two distinct concepts in the tree of markup languages. You can't exactly replace HTML with XML . XML can be viewed as a generalized form of HTML, but even that is imprecise. You mainly use HTML to display data, and XML to carry(or store) the data.

This link is helpful: How to read HTML as XML?

More here - difference between HTML and XML

If you are storing values via any programming language

Here is an example in C#

To store date you have to convert it first and then store it

insert table1 (foodate)
   values (FooDate.ToString("MM/dd/yyyy"));

FooDate is datetime variable which contains your date in your format.

This selector should work but will be more efficient if you replace it with your suited markup:

//*[contains(@class, 'Test')]

Or, since we know the sought element is a div:

//div[contains(@class, 'Test')]

But since this will also match cases like class="Testvalue" or class="newTest", @Tomalak's version provided in the comments is better:

//div[contains(concat(' ', @class, ' '), ' Test ')]

If you wished to be really certain that it will match correctly, you could also use the normalize-space function to clean up stray whitespace characters around the class name (as mentioned by @Terry):

//div[contains(concat(' ', normalize-space(@class), ' '), ' Test ')]

Note that in all these versions, the * should best be replaced by whatever element name you actually wish to match, unless you wish to search each and every element in the document for the given condition.

Do this:

<ToggleButton 
        android:id="@+id/toggle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/check"   <!--check.xml-->
        android:layout_margin="10dp"
        android:textOn=""
        android:textOff=""
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_centerVertical="true"/>

create check.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/selected_image"
          android:state_checked="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/unselected_image"
        android:state_checked="false"/>

 </selector>

You need to give required = false for name and password request parameters as well. That's because, when you provide just the logout parameter, it actually expects for name and password as well as they are still mandatory.

It worked when you just gave name and password because logout wasn't a mandatory parameter thanks to required = false already given for logout.

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

Try

<p>Click on <img src="/storage/help/button2.1.png" width="auto" 
height="28"align="middle"/> button will show a page as bellow</p>

It works for me

You're trying to declare strategy twice, and that's why you're getting the above error. The following works without any complaints (compiled with gcc -ansi -pedantic -Wall):

#include <stdio.h>

enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;

int main(int argc, char** argv){
    printf("strategy: %d\n", strategy);

    return 0;
}

If instead of the above, the second line were changed to:

...
enum { RANDOM, IMMEDIATE, SEARCH } strategy;
strategy = IMMEDIATE;
...

From the warnings, you could easily see your mistake:

enums.c:5:1: warning: data definition has no type or storage class [enabled by default]
enums.c:5:1: warning: type defaults to ‘int’ in declaration of ‘strategy’ [-Wimplicit-int]
enums.c:5:1: error: conflicting types for ‘strategy’
enums.c:4:36: note: previous declaration of ‘strategy’ was here

So the compiler took strategy = IMMEDIATE for a declaration of a variable called strategy with default type int, but there was already a previous declaration of a variable with this name.

However, if you placed the assignment in the main() function, it would be a valid code:

#include <stdio.h>

enum { RANDOM, IMMEDIATE, SEARCH } strategy = IMMEDIATE;

int main(int argc, char** argv){
    strategy=SEARCH;
    printf("strategy: %d\n", strategy);

    return 0;
}

Use an outer wrapper div set to 100% and then your inner wrapper div 100% should be now relative to that.

I thought for sure this used to work for me, but apparently not:

<html>
<body>
<div id="outerwrapper" style="border : 1px solid red ; height : 100%">
<div id="header" style="border : 1px solid blue ; height : 60px"></div>
<div id="wrapper"  style="border : 1px solid green ; height : 100% ; overflow : scroll ;">
  <div id="left" style="height : 100% ; width : 50% ; overflow : scroll; float : left ; clear : left ;">Some text 

on the left</div>
  <div id="right" style="height : 100% ; width 50% ; overflow : scroll; float : left ;">Some Text on the 

right</div>
</div>
</div>
</body>
</html>

As for least squares fit, here are a couple other things to experiment with:

1. Just because it's least squares fit doesn't mean that it has to be linear. You can least-squares-fit a quadratic curve to the data, then this would fit a scenario in which the user is accelerating. (Note that by least squares fit I mean using the coordinates as the dependent variable and time as the independent variable.)

2. You could also try weighting the data points based on reported accuracy. When the accuracy is low weight those data points lower.

3. Another thing you might want to try is rather than display a single point, if the accuracy is low display a circle or something indicating the range in which the user could be based on the reported accuracy. (This is what the iPhone's built-in Google Maps application does.)

I don't use Retrofit and for OkHttp here is the only solution for self-signed certificate that worked for me:

   echo -n | openssl s_client -connect elkews.com:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ./res/raw/elkews_cert.crt
   

2. Use Paulo answer to set ssl factory (nowadays using OkHttpClient.Builder()) but without RestAdapter creation.

3. Then add the following solution to fix: SSLPeerUnverifiedException: Hostname not verified

So the end of Paulo's code (after sslContext initialization) that is working for me looks like the following:

...
OkHttpClient.Builder builder = new OkHttpClient.Builder().sslSocketFactory(sslContext.getSocketFactory());
builder.hostnameVerifier(new HostnameVerifier() {
  @Override
  public boolean verify(String hostname, SSLSession session) {
    return "secure.elkews.com".equalsIgnoreCase(hostname);
});
OkHttpClient okHttpClient = builder.build();

I will repeat what the others said, but will just try to make it simpler...

First, just create the Interface class

public interface PostTaskListener<K> {
    // K is the type of the result object of the async task 
    void onPostTask(K result);
}

Second, create the AsyncTask (which can be an inner static class of your activity or fragment) that uses the Interface, by including a concrete class. In the example, the PostTaskListener is parameterized with String, which means it expects a String class as a result of the async task.

public static class LoadData extends AsyncTask<Void, Void, String> {

    private PostTaskListener<String> postTaskListener;

    protected LoadData(PostTaskListener<String> postTaskListener){
        this.postTaskListener = postTaskListener;
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);

        if (result != null && postTaskListener != null)
            postTaskListener.onPostTask(result);
    }
}

Finally, the part where your combine your logic. In your activity / fragment, create the PostTaskListener and pass it to the async task. Here is an example:

...
PostTaskListener<String> postTaskListener = new PostTaskListener<String>() {
    @Override
    public void onPostTask(String result) {
        //Your post execution task code
    }
}

// Create the async task and pass it the post task listener.
new LoadData(postTaskListener);

Done!

You can just use the Paths class:

Path path = Paths.get(textPath);

... assuming you want to use the default file system, of course.

This may or may not help you address your problem, OP, but to get the timezone of the current server relative to UTC (UT1, technically), do:

SELECT EXTRACT(TIMEZONE FROM now())/3600.0;

The above works by extracting the UT1-relative offset in minutes, and then converting it to hours using the factor of 3600 secs/hour.

Example:

SET SESSION timezone TO 'Asia/Kabul';
SELECT EXTRACT(TIMEZONE FROM now())/3600.0;
-- output: 4.5 (as of the writing of this post)

(docs).

The following query gives names of all sequences.

SELECT c.relname FROM pg_class c WHERE c.relkind = 'S';

Typically a sequence is named as ${table}_id_seq. Simple regex pattern matching will give you the table name.

To get last value of a sequence use the following query:

SELECT last_value FROM test_id_seq;

Editing Dialogs

One good ability to edit dialogs is using SharpDevelop in a version 4.0.1.7090 (or higher). With help of this tool a standalone dialog (wxs files from WiX sources like e.g. InstallDirDlg.wxs) can be opened, previewed and edited in Design view.

Use mapply

> df <- data.frame(x=c(1,2), y=c(3,4), z=c(5,6))
> df
  x y z
1 1 3 5
2 2 4 6
> mapply(function(x,y) x+y, df$x, df$z)
[1] 6 8

> cbind(df,f = mapply(function(x,y) x+y, df$x, df$z) )
  x y z f
1 1 3 5 6
2 2 4 6 8

Your code makes no sense, maybe because it's out of context.

If you mean code like this:

$('a').click(function () {
    callFunction();
    return false;
});

The return false will return false to the click-event. That tells the browser to stop following events, like follow a link. It has nothing to do with the previous function call. Javascript runs from top to bottom more or less, so a line cannot affect a previous line.

Based on @ionden's answer, the call to the delegate could be simplified using null propagation since C# 6.0.

Your code would simply be:

class MyClass {
    public event EventHandler MyEvent;

    public void Method() {
        MyEvent?.Invoke(this, EventArgs.Empty);
    }
}

Use it like this:

MyClass myObject = new MyClass();
myObject.MyEvent += new EventHandler(myObject_MyEvent);
myObject.Method();

Drop the hash - that's for identifying the id attribute.

I don't remember the specific source, but I am using:

    /* Number of Cards by Row based on Viewport */
    @media (min-width: 576px) {
        .card-deck .card {
            min-width: 50.1%; /* 1 Column */
            margin-bottom: 12px;
        }
    }
    @media (min-width: 768px) {
        .card-deck .card {
            min-width: 33.4%;  /* 2 Columns */
        }
    }
    @media (min-width: 1200px) {
        .card-deck .card {
            min-width: 25.1%;  /* 3 Columns */
        }
    }

You may want to tinker with the specific values to fit your needs.

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

I came across this one that is written in java javaANPR, I am looking for a c# library as well.

I would like a system where I can point a video camera at some sailing boats, all of which have large, identifiable numbers on them, and have it identify the boats and send a tweet when they sail past a video camera.

This works for me:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- NOTE: order is important (the first matching state(s) is what is rendered) -->
    <item 
        android:state_selected="true" 
        android:drawable="@drawable/info_icon_solid_with_shadow" />
    <item 
        android:drawable="@drawable/info_icon_outline_with_shadow" />
 </selector>

And then in java:

//assign the image in code (or you can do this in your layout xml with the src attribute)
imageButton.setImageDrawable(getBaseContext().getResources().getDrawable(R.drawable....));

//set the click listener
imageButton.setOnClickListener(new OnClickListener() {

    public void onClick(View button) {
        //Set the button's appearance
        button.setSelected(!button.isSelected());

        if (button.isSelected()) {
            //Handle selected state change
        } else {
            //Handle de-select state change
        }

    }

});

For smooth transition you can also mention animation time:

<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="@android:integer/config_mediumAnimTime">

like '%[\_]%'

Add [ ] did the job for me

If you are on mac, Use rvm to install your specific version of ruby. See https://owanateamachree.medium.com/how-to-install-ruby-using-ruby-version-manager-rvm-on-macos-mojave-ab53f6d8d4ec

Make sure you follow all the steps. This worked for me.

A practical example when name() and toString() make sense to be different is a pattern where single-valued enum is used to define a singleton. It looks surprisingly at first but makes a lot of sense:

enum SingletonComponent {
    INSTANCE(/*..configuration...*/);

    /* ...behavior... */

    @Override
    String toString() {
      return "SingletonComponent"; // better than default "INSTANCE"
    }
}

In such case:

SingletonComponent myComponent = SingletonComponent.INSTANCE;
assertThat(myComponent.name()).isEqualTo("INSTANCE"); // blah
assertThat(myComponent.toString()).isEqualTo("SingletonComponent"); // better

function getYearDiff(startDate, endDate) {
    let yearDiff = endDate.getFullYear() - startDate.getFullYear();
    if (startDate.getMonth() > endDate.getMonth()) {
        yearDiff--;
    } else if (startDate.getMonth() === endDate.getMonth()) {
        if (startDate.getDate() > endDate.getDate()) {
            yearDiff--;
        } else if (startDate.getDate() === endDate.getDate()) {
            if (startDate.getHours() > endDate.getHours()) {
                yearDiff--;
            } else if (startDate.getHours() === endDate.getHours()) {
                if (startDate.getMinutes() > endDate.getMinutes()) {
                    yearDiff--;
                }
            }
        }
    }
    return yearDiff;
}

alert(getYearDiff(firstDate, secondDate));

This can also happen if you have this restriction:

Please enter the commit message for your changes. Lines starting with '#' will be ignored, and an empty message aborts the commit.

and you do like me: write a commit message starting with "#" .....

I had the same error, but I already had the commit-msg and did the rebase and everything. Very silly mistake though :D

I had the same issue and tried everything. This 400 happened for an upstream proxy. Debug logged showed absolutely nothing.

The problem was in duplicate proxy_set_header Host $http_host directive, which I didn't notice initially. Removing duplicate one solved the issue immediately. I wish nginx was saying something other than 400 in this scenario, as nginx -t didn't complain at all.

P.S. this happened while migrating from older nginx 1.10 to the newer 1.19. Before it was tolerated apparently.

SELECT sal FROM (
    SELECT sal, row_number() OVER (order by sal desc) AS rn FROM emp
)
WHERE rn = 3

Yes, it will take longer to execute if the table is big. But for "N-th row" queries the only way is to look through all the data and sort it. It will be definitely much faster if you have an index on sal.

1. My experimenting indicates that the runas command must include the admin user's domain (at least it does in my organization's environmental setup):

   runas /user:AdminDomain\AdminUserName ExampleScript.bat
   

   If you don’t already know the admin user's domain, run an instance of Command Prompt as the admin user, and enter the following command:

   echo %userdomain%
   

2. The answers provided by both Kerrek SB and Ed Greaves will execute the target file under the admin user but, if the file is a Command script (.bat file) or VB script (.vbs file) which attempts to operate on the normal-login user’s environment (such as changing registry entries), you may not get the desired results because the environment under which the script actually runs will be that of the admin user, not the normal-login user! For example, if the file is a script that operates on the registry’s HKEY_CURRENT_USER hive, the affected “current-user” will be the admin user, not the normal-login user.

the different log levels are helpful for tools, whose can anaylse you log files. Normally a logfile contains lots of information. To avoid an information overload (or here an stackoverflow^^) you can use the log levels for grouping the information.

Before the days of jQuery you would use:

   document.getElementById('findmebyid');

If this one line will save you an entire jQuery library, it might be worth while using it instead.

For those concerned about performance: Beginning your selector with an ID is always best as it uses native function document.getElementById.

// Fast:
$( "#container div.robotarm" );

// Super-fast:
$( "#container" ).find( "div.robotarm" );

Take a look at the Java™ Tutorials by Oracle.

But basically, as dacwe said, use break.

If you can it is often clearer to avoid using break and put the check as a condition of the while loop, or using something like a do while loop. This isn't always possible though.

Naive question: Is it possible to somehow download GLIBC 2.15, put it in any folder (e.g. /tmp/myglibc) and then point to this path ONLY when executing something that needs this specific version of glibc?

Yes, it's possible.

The default value is indeed false.

However you can't use a local variable is it's not been assigned first.

You can use the default keyword to verify:

bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }

I used the instructions in this step-by-step and it worked.

Labeeb is right about why you need to set image using path if your resources are already laying inside the resource folder ,

This kind of path is needed only when your images are stored in SD-Card .

And try the below code to set Bitmap images from a file stored inside a SD-Card .

File imgFile = new  File("/sdcard/Images/test_image.jpg");

if(imgFile.exists()){

    Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

    ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);

    myImage.setImageBitmap(myBitmap);

}

And include this permission in the manifest file:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I think the others have answered your second question. As for the first, the "Hello World" of CUDA, I don't think there is a set standard, but personally, I'd recommend a parallel adder (i.e. a programme that sums N integers).

If you look the "reduction" example in the NVIDIA SDK, the superficially simple task can be extended to demonstrate numerous CUDA considerations such as coalesced reads, memory bank conflicts and loop unrolling.

See this presentation for more info:

http://www.gpgpu.org/sc2007/SC07_CUDA_5_Optimization_Harris.pdf

I'm not sure I fully understand the question but I'll attempt to answer by providing a few details about profiles in Spring Boot.

For your #1 example, according to the docs you can select the profile using the Spring Boot Maven plugin using -Drun.profiles.

Edit: For Spring Boot 2.0+ run has been renamed to spring-boot.run and run.profiles has been renamed to spring-boot.run.profiles

mvn spring-boot:run -Dspring-boot.run.profiles=dev

https://docs.spring.io/spring-boot/docs/2.0.1.RELEASE/maven-plugin/examples/run-profiles.html

From your #2 example, you are defining the active profile after the name of the jar. You need to provide the JVM argument before the name of the jar you are running.

java -jar -Dspring.profiles.active=dev XXX.jar

General info:

You mention that you have both an application.yml and a application-dev.yml. Running with the dev profile will actually load both config files. Values from application-dev.yml will override the same values provided by application.yml but values from both yml files will be loaded.

There are also multiple ways to define the active profile.

You can define them as you did, using -Dspring.profiles.active when running your jar. You can also set the profile using a SPRING_PROFILES_ACTIVE environment variable or a spring.profiles.active system property.

More info can be found here: https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-set-active-spring-profiles

the short term solution is to use the default iis host and port normally 120.0.0.1 and 80 respectively. However am still looking for a more versatile solution.

string StringFold(string input, Func<char, string> proc)
{
  return string.Concat(input.Select(proc).ToArray());
}

string FoldProc(char input)
{
  if (input >= 128)
  {
    return string.Format(@"\u{0:x4}", (int)input);
  }
  return input.ToString();
}

string EscapeToAscii(string input)
{
  return StringFold(input, FoldProc);
}

Here is my solution with reduce and Optional:

private Optional<SimpleImmutableEntry<String, String>> splitKeyValue(String text) {
    String[] v = text.split("=");
    if (v.length == 1 || v.length == 2) {
        String key = URLDecoder.decode(v[0], StandardCharsets.UTF_8);
        String value = v.length == 2 ? URLDecoder.decode(v[1], StandardCharsets.UTF_8) : null;
        return Optional.of(new SimpleImmutableEntry<String, String>(key, value));
    } else
        return Optional.empty();
}

private HashMap<String, String> parseQuery(URI uri) {
    HashMap<String, String> params = Arrays.stream(uri.getQuery()
            .split("&"))
            .map(this::splitKeyValue)
            .filter(Optional::isPresent)
            .map(Optional::get)
            .reduce(
                // initial value
                new HashMap<String, String>(), 
                // accumulator
                (map, kv) -> {
                     map.put(kv.getKey(), kv.getValue()); 
                     return map;
                }, 
                // combiner
                (a, b) -> {
                     a.putAll(b); 
                     return a;
                });
    return params;
}

• I ignore duplicate parameters (I take the last one).
• I use Optional<SimpleImmutableEntry<String, String>> to ignore garbage later
• The reduction start with an empty map, then populate it on each SimpleImmutableEntry

In case you ask, reduce requires this weird combiner in the last parameter, which is only used in parallel streams. Its goal is to merge two intermediate results (here HashMap).

One another way without regex:

function trimLeadingZerosSubstr(str) {
    var xLastChr = str.length - 1, xChrIdx = 0;
    while (str[xChrIdx] === "0" && xChrIdx < xLastChr) {
        xChrIdx++;
    }
    return xChrIdx > 0 ? str.substr(xChrIdx) : str;
}

With short string it will be more faster than regex (jsperf)

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

An old post but thought i would share an answer for anyone looking. And because when you use absolute things can go wrong. What I would do is

HTML

<div id="parentDiv"></div>
<div class="childDiv"></div>

The Css

parentDiv{

}
childDiv{
    height:40px;
    margin-top:-20px;
}

And that would just sit that bottom div back up into the parent div. safe for most browsers too

One solution to this problem is to use the Handler.postDelayed() method. Some Google training materials suggest the same solution.

public void onClick(View v) {
    my_button.setBackgroundResource(R.drawable.icon);

    Handler handler = new Handler(); 
    handler.postDelayed(new Runnable() {
         @Override 
         public void run() { 
              my_button.setBackgroundResource(R.drawable.defaultcard); 
         } 
    }, 2000); 
}

However, some have pointed out that the solution above causes a memory leak because it uses a non-static inner and anonymous class which implicitly holds a reference to its outer class, the activity. This is a problem when the activity context is garbage collected.

A more complex solution that avoids the memory leak subclasses the Handler and Runnable with static inner classes inside the activity since static inner classes do not hold an implicit reference to their outer class:

private static class MyHandler extends Handler {}
private final MyHandler mHandler = new MyHandler();

public static class MyRunnable implements Runnable {
    private final WeakReference<Activity> mActivity;

    public MyRunnable(Activity activity) {
        mActivity = new WeakReference<>(activity);
    }

    @Override
    public void run() {
        Activity activity = mActivity.get();
        if (activity != null) {
            Button btn = (Button) activity.findViewById(R.id.button);
            btn.setBackgroundResource(R.drawable.defaultcard);
        }
    }
}

private MyRunnable mRunnable = new MyRunnable(this);

public void onClick(View view) {
    my_button.setBackgroundResource(R.drawable.icon);

    // Execute the Runnable in 2 seconds
    mHandler.postDelayed(mRunnable, 2000);
}

Note that the Runnable uses a WeakReference to the Activity, which is necessary in a static class that needs access to the UI.

Jonty, I'm struggling with this too.

I think there's a clue in here:

otool -L /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle

/Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle:
    /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/libruby.1.dylib (compatibility version 1.8.0, current version 1.8.7)
    libmysqlclient.16.dylib (compatibility version 16.0.0, current version 16.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.1)

Notice the path to the dylib is, uh, rather short?

I'm trying to figure out where the gem install instructions are leaving off the dylib path, but it's slow going as I have never built a gem myself.

I'll post more if I find more!

You don't have to use CASE...WHEN, you could use an OR condition, like this:

WHERE
  pw='correct'
  AND (id>=800 OR success=1) 
  AND YEAR(timestamp)=2011

this means that if id<800, success has to be 1 for the condition to be evaluated as true. Otherwise, it will be true anyway.

It is less common, however you could still use CASE WHEN, like this:

WHERE
  pw='correct'
  AND CASE WHEN id<800 THEN success=1 ELSE TRUE END 
  AND YEAR(timestamp)=2011

this means: return success=1 (which can be TRUE or FALSE) in case id<800, or always return TRUE otherwise.

I solved changing

readable_json['firstName']

by

readable_json[0]['firstName']

see my answer here:

How can I get the current date and time in UTC or GMT in Java?

I've fully tested it by changing the timezones on the emulator

You should use textView.setGravity(Gravity.CENTER_HORIZONTAL);.

Remember that using

LinearLayout.LayoutParams layoutParams =new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
layoutParams2.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;

won't work. This will set the gravity for the widget and not for it's text.

Use str.replace.

>>> papa.replace('papa', '')
' is a good man'
>>> app.replace('papa', '')
'app is important'

Alternatively use re and use regular expressions. This will allow the removal of leading/trailing spaces.

>>> import re
>>> papa = 'papa is a good man'
>>> app = 'app is important'
>>> papa3 = 'papa is a papa, and papa'
>>>
>>> patt = re.compile('(\s*)papa(\s*)')
>>> patt.sub('\\1mama\\2', papa)
'mama is a good man'
>>> patt.sub('\\1mama\\2', papa3)
'mama is a mama, and mama'
>>> patt.sub('', papa3)
'is a, and'

The current (as of version 0.20) method for changing column names after a groupby operation is to chain the rename method. See this deprecation note in the documentation for more detail.

Deprecated Answer as of pandas version 0.20

This is the first result in google and although the top answer works it does not really answer the question. There is a better answer here and a long discussion on github about the full functionality of passing dictionaries to the agg method.

These answers unfortunately do not exist in the documentation but the general format for grouping, aggregating and then renaming columns uses a dictionary of dictionaries. The keys to the outer dictionary are column names that are to be aggregated. The inner dictionaries have keys that the new column names with values as the aggregating function.

Before we get there, let's create a four column DataFrame.

df = pd.DataFrame({'A' : list('wwwwxxxx'), 
                   'B':list('yyzzyyzz'), 
                   'C':np.random.rand(8), 
                   'D':np.random.rand(8)})

   A  B         C         D
0  w  y  0.643784  0.828486
1  w  y  0.308682  0.994078
2  w  z  0.518000  0.725663
3  w  z  0.486656  0.259547
4  x  y  0.089913  0.238452
5  x  y  0.688177  0.753107
6  x  z  0.955035  0.462677
7  x  z  0.892066  0.368850

Let's say we want to group by columns A, B and aggregate column C with mean and median and aggregate column D with max. The following code would do this.

df.groupby(['A', 'B']).agg({'C':['mean', 'median'], 'D':'max'})

            D         C          
          max      mean    median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This returns a DataFrame with a hierarchical index. The original question asked about renaming the columns in the same step. This is possible using a dictionary of dictionaries:

df.groupby(['A', 'B']).agg({'C':{'C_mean': 'mean', 'C_median': 'median'}, 
                            'D':{'D_max': 'max'}})

            D         C          
        D_max    C_mean  C_median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This renames the columns all in one go but still leaves the hierarchical index which the top level can be dropped with df.columns = df.columns.droplevel(0).

Try this

If @NewStatus  = 'InOffice' 
BEGIN
     Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'OutOffice'
BEGIN
    Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'Home'
BEGIN
    Update tblEmployee set Home = -1 where EmpID = @EmpID
END

This should work...

JavaScriptSerializer ser = new JavaScriptSerializer();

BigDecimal can be used, good explanation of why to not use Float or Double can be seen here: Why not use Double or Float to represent currency?

I made this useful table with all the cases:

blank?, present? are provided by Rails.

In recent versions of python, you can use marshmallow-dataclass:

from marshmallow_dataclass import dataclass

@dataclass
class Payload
    action:str
    method:str
    data:str

Payload.Schema().load({"action":"print","method":"onData","data":"Madan Mohan"})

Your code should be something like

require_once('class.twitter.php');

$t = new twitter;
$t->username = 'user';
$t->password = 'password';

$data = $t->publicTimeline();

Regex:

[RegularExpression(@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", ErrorMessage = "Please enter a valid e-mail adress")]

Or you can use just:

    [DataType(DataType.EmailAddress)]
    public string Email { get; set; }

I already wrote up the answer to this but it seems to have been deleted. The issue was that YUI added background-color:white to the HTML element. I overwrote that and everything was easy to handle from there.

You can use either textBox1.select(); or the TabIndex in textbox setting. TabIndex=0 focoused first.

I got same issue on Catalina mac. I also installed the R from the source in following diretory. ./Documents/R-4.0.3

Now from the terminal type

 ls -a 

and open

 vim .bash_profile 

type

export LANG="en_US.UTF-8"

save with :wq

then type

source .bash_profile 

and then open

./Documents/R-4.0.3/bin/R 
./Documents/R-4.0.3/bin/Rscript 

I always have to run "source /Users/yourComputerName/.bash_profile" before running R scripts.

You can use awk:

awk '{ sum += $1 } END { print sum }' file

I'm sure git subtree is all fine and wonderful, but my subdirectories of git managed code that I wanted to move was all in eclipse. So if you're using egit, it's painfully easy. Take the project you want to move and team->disconnect it, and then team->share it to the new location. It will default to trying to use the old repo location, but you can uncheck the use-existing selection and pick the new place to move it. All hail egit.

I had also the same problem and fix it via Jenkins Console.

Go to "Manage Jenkins" > "Script Console" and run a script:

 Jenkins .instance.getItemByFullName("JobName")
        .getBuildByNumber(JobNumber)
        .finish(hudson.model.Result.ABORTED, new java.io.IOException("Aborting build")); 

You'll have just specify your JobName and JobNumber.

We're using Install4J to build installers for windows or unix environments.

It's easily customizable up to the point where you want to write scripts for special actions that cannot be done with standard dialogues. But even though we're setting up windows services with it, we're only using standard components.

• installer + launcher
• windows or unix
• scriptable in Java
• ant task
• lots of customizable standard panels and actions
• optionally includes or downloads a JRE
• can also launch windows services
• multiple languages

I think Launch4J is from the same company (just the launcher - no installer).

PS: sadly i'm not getting paid for this endorsement. I just like that tool.

You have more than one form tags with runat="server" on your template, most probably you have one in your master page, remove one on your aspx page, it is not needed if already have form in master page file which is surrounding your content place holders.

Try to remove that tag:

<form id="formID" runat="server">

and of course closing tag:

</form>

Convert.ToInt32(myobject);

This will handle the case where myobject is null and return 0, instead of throwing an exception.

I used the following code to listen to changes to an array.

/* @arr array you want to listen to
   @callback function that will be called on any change inside array
 */
function listenChangesinArray(arr,callback){
     // Add more methods here if you want to listen to them
    ['pop','push','reverse','shift','unshift','splice','sort'].forEach((m)=>{
        arr[m] = function(){
                     var res = Array.prototype[m].apply(arr, arguments);  // call normal behaviour
                     callback.apply(arr, arguments);  // finally call the callback supplied
                     return res;
                 }
    });
}

Hope this was useful :)

You'll need a using System.Net.Http at the top.

You don't need to use a type assertion, instead just use the %v format specifier with Sprintf:

hostAndPort := fmt.Sprintf("%v:%v", arguments["<host>"], arguments["<port>"])

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

Use HH for 24 hour hours format:

DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")

Or the tt format specifier for the AM/PM part:

DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")

Take a look at the custom Date and Time format strings documentation.

Use --build-arg in lower case environment variable:

docker build --build-arg http_proxy=http://proxy:port/ --build-arg https_proxy=http://proxy:port/ --build-arg ftp_proxy=http://proxy:port --build-arg no_proxy=localhost,127.0.0.1,company.com -q=false .

HTML:

<div class="item row">
    <div class="col-xs-12 col-sm-6"><h4>This is some text.</h4></div>
    <div class="col-xs-12 col-sm-6"><h4>This is some more.</h4></div>
</div>

CSS:

div.item div h4 {
    height: 60px;
    vertical-align: middle;    
    display: table-cell;
}

Important notes:

• The vertical-align: middle; display: table-cell; must be applied to a tag that has no Bootstrap classes applied; it cannot be a col-*, a row, etc.
• This can't be done without this extra, possibly pointless tag in your HTML, unfortunately.
• The backgrounds are unnecessary - they're just there for demo purposes. So, you don't need to apply any special rules to the row or col-* tags.
• It is important to notice the inner tag does not stretch to 100% of the width of its parent; in our scenario this didn't matter but it may to you. If it does, you end up with something closer to some of the other answers here:

http://jsfiddle.net/b9chris/zN39r/1/

CSS:

div.item div {
    background: #fdd;
    table-layout: fixed;
    display: table;
}
div.item div h4 {
    height: 60px;
    vertical-align: middle;    
    display: table-cell;
    background: #eee;
}

Notice the added table-layout and display properties on the col-* tags. This must be applied to the tag(s) that have col-* applied; it won't help on other tags.

Question is a little vague.

list_of_lines = multiple_lines.split("\n")
for line in list_of_lines:
    list_of_items_in_line = line.split(",")
    first_int = int(list_of_items_in_line[0])

etc.

DateTime dt1 = new DateTime(2009, 3, 14);
DateTime dt2 = new DateTime(2008, 3, 15);

int diffMonth = Math.Abs((dt2.Year - dt1.Year)*12 + dt1.Month - dt2.Month)

You can use the python-n2w library, Just do

pip install n2w

then simply

print(n2w.convert(your-number-here))

This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.

If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.

Look at here for a similar problem that occured Silverlight: Value does not fall within the expected range exception

Cheers,

First you must test the query list size; here a example:

long count;
if (query.list().size() > 0)
    count=(long) criteria.list().get(0);   
else
    count=0;            
return count;

If you have the sqlite database, use the sqlite3 command line program and these commands:

To list all the tables in the database:

.tables

To show the schema for a given tablename:

.schema tablename

Since PostgreSQL 10

CREATE TABLE test_new (
    id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
    payload text
);

A simple way would be to use

Math.max(min, Math.min(number, max));

and you can obviously define a function that wraps this:

function clamp(number, min, max) {
  return Math.max(min, Math.min(number, max));
}

Originally this answer also added the function above to the global Math object, but that's a relic from a bygone era so it has been removed (thanks @Aurelio for the suggestion)

Follow a few steps:-
1) Clean Project
If 1 doesn't work then
2) Invalidate cache and restart 
If 2 doesn't work then 
3) run command in the project folder rm -r .idea

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

If you're trying to find the first count multiples of m, something like this would work:

def multiples(m, count):
    for i in range(count):
        print(i*m)

Alternatively, you could do this with range:

def multiples(m, count):
    for i in range(0,count*m,m):
        print(i)

Note that both of these start the multiples at 0 - if you wanted to instead start at m, you'd need to offset it by that much:

range(m,(count+1)*m,m)

The ZingChart library has an AngularJS directive that was built in-house. Features include:

• Full access to the entire ZingChart library (all charts, maps, and features)
• Takes advantage of Angular's 2-way data binding, making data and chart elements easy to update

• Support from the development team

  ...
  $scope.myJson = {
  type : 'line',
     series : [
        { values : [54,23,34,23,43] },{ values : [10,15,16,20,40] }
     ]
  };
  ...
  
  <zingchart id="myChart" zc-json="myJson" zc-height=500 zc-width=600></zingchart>

If you don't want to import csv module for that, you can write a list of lists to a csv file using only Python built-ins

with open("output.csv", "w") as f:
    for row in a:
        f.write("%s\n" % ','.join(str(col) for col in row))

User JQuery is EmptyObject to check whether array is contains elements or not.

var testArray=[1,2,3,4,5];
var testArray1=[];
console.log(jQuery.isEmptyObject(testArray)); //false
console.log(jQuery.isEmptyObject(testArray1)); //true

I had a requirement to take values from text file and use as key value pair. i have content in text file as key = value, so i have used split method with separator as "=" and wrote below code

d = {}
file = open("filename.txt")
for x in file:
    f = x.split("=")
    d.update({f[0].strip(): f[1].strip()})

By using strip method any spaces before or after the "=" separator are removed and you will have the expected data in dictionary format

I need to do this and have the <dt> content vertically centered, relative to the <dd> content. I used display: inline-block, together with vertical-align: middle

See full example on Codepen here

.dl-horizontal {
  font-size: 0;
  text-align: center;

  dt, dd {
    font-size: 16px;
    display: inline-block;
    vertical-align: middle;
    width: calc(50% - 10px);
  }

  dt {
    text-align: right;
    padding-right: 10px;
  }

  dd {
    font-size: 18px;
    text-align: left;
    padding-left: 10px;
  } 
}

You can use <LinearLayout> to group elements horizontaly. Also you should use style to set margins, background and other properties. This will allow you not to repeat code for every label you use. Here is an example:

<LinearLayout
                    style="@style/FormItem"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="horizontal">
                <TextView
                        style="@style/FormLabel"
                        android:layout_width="wrap_content"
                        android:layout_height="@dimen/default_element_height"
                        android:text="@string/name_label"
                        />

                <EditText
                        style="@style/FormText.Editable"
                        android:id="@+id/cardholderName"
                        android:layout_width="wrap_content"
                        android:layout_height="@dimen/default_element_height"
                        android:layout_weight="1"
                        android:gravity="right|center_vertical"
                        android:hint="@string/card_name_hint"
                        android:imeOptions="actionNext"
                        android:singleLine="true"
                        />
            </LinearLayout>

Also you can create a custom view base on the layout above. Have you looked at Creating custom view ?

You've already got it: A if test else B is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:

{ (some_key if condition else default_key):(something_if_true if condition
          else something_if_false) for key, value in dict_.items() }

The final if clause acts as a filter, which is different from having the conditional expression.

There's only one registered mediatype for SVG, and that's the one you listed, image/svg+xml. You can of course serve SVG as XML too, though browsers tend to behave differently in some scenarios if you do, for example I've seen cases where SVG used in CSS backgrounds fail to display unless served with the image/svg+xml mediatype.

hash_items = {:item => 1}
puts hash_items 
#hash_items will give you {:item => 1}

hash_items.merge!({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}

hash_items.merge({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}, but the original variable will be the same old one.

In case someone had this issue using React, this is how I solved it.

scss:

#loginBackdrop {
position: absolute;
width: 100% !important;
height: 100% !important;
top:0px;
left:0px;
z-index: 9; }

#loginFrame {
width: $iFrameWidth;
height: $iFrameHeight;
background-color: $mainColor;
position: fixed;
z-index: 10;
top: 50%;
left: 50%;
margin-top: calc(-1 * #{$iFrameHeight} / 2);
margin-left: calc(-1 * #{$iFrameWidth} / 2);
border: solid 1px grey;
border-radius: 20px;
box-shadow: 0px 0px 90px #545454; }

Component's render():

render() {
    ...
    return (
        <div id='loginBackdrop' onClick={this.props.closeLogin}>
            <div id='loginFrame' onClick={(e)=>{e.preventDefault();e.stopPropagation()}}>
             ... [modal content] ...
            </div>
        </div>
    )
}

By a adding an onClick function for the child modal (content div) mouse click events are prevented to reach the 'closeLogin' function of the parent element.

This did the trick for me and I was able to create a modal effect with 2 simple divs.

Something like this?

public static T ConvertValue<T>(string value)
{
    return (T)Convert.ChangeType(value, typeof(T));
}

You can then use it like this:

int val = ConvertValue<int>("42");

Edit:

You can even do this more generic and not rely on a string parameter provided the type U implements IConvertible - this means you have to specify two type parameters though:

public static T ConvertValue<T,U>(U value) where U : IConvertible
{
    return (T)Convert.ChangeType(value, typeof(T));
}

I considered catching the InvalidCastException exception that might be raised by Convert.ChangeType() - but what would you return in this case? default(T)? It seems more appropriate having the caller deal with the exception.

In older versions of jquery you'll have to do it the "javascript way" using settimeout

setTimeout( function(){$('div').hide();} , 4000);

or

setTimeout( "$('div').hide();", 4000);

Recently with jquery 1.4 this solution has been added:

$("div").delay(4000).hide();

Of course replace "div" by the correct element using a valid jquery selector and call the function when the document is ready.

Looks like you forgot adding correct headers to your get request (ask the REST API developer or you specific API description):

HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.header("Accept", "application/xml")
connection.setRequestMethod("GET");
connection.connect();

or

connection.header("Accept", "application/xml;version=1")

I am not sure what you really want here. If you want to see the .NET framework source code, you may try Netmassdownloader. It's free.

If you want to see any assembly's code (not just .NET), you can use ReSharper. Although it's not free.

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

Sure it is OK. Actually you can see for yourself easily:

l = range(12000)
l = sorted(l, reverse=True)

Running the those lines on my machine took:

real    0m0.036s
user    0m0.024s
sys  0m0.004s

But sure as everyone else said. The larger the array the slower the operations will be.

You do it exactly as you showed with this line:

get.setHeader("Content-Type", "application/x-zip");

So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.

on the server side in node.js I just added this and it worked. reactjs front end on my local machine can access api backend hosted on azure:

// Enables CORS
const cors = require('cors');
app.use(cors({ origin: true }));

Given you're looking for a simple formula, this is probably the simplest way to do it, assuming that the Earth is a sphere with a circumference of 40075 km.

Length in meters of 1° of latitude = always 111.32 km

Length in meters of 1° of longitude = 40075 km * cos( latitude ) / 360

According to the RFC7231 - page59(https://tools.ietf.org/html/rfc7231#page-59) the definition of 404 status code response is:

6.5.4. 404 Not Found The 404 (Not Found) status code indicates that the origin server did not find a current representation for the target resource or is not willing to disclose that one exists. A 404 status code does not indicate whether this lack of representation is temporary or permanent; the 410 (Gone) status code is preferred over 404 if the origin server knows, presumably through some configurable means, that the condition is likely to be permanent. A 404 response is cacheable by default; i.e., unless otherwise indicated by the method definition or explicit cache controls (see Section 4.2.2 of [RFC7234]).

And the main thing that brings doubts is the definition of resource in the context above. According the same RFC(7231) the definition of resource is:

Resources: The target of an HTTP request is called a "resource". HTTP does not limit the nature of a resource; it merely defines an interface that might be used to interact with resources. Each resource is identified by a Uniform Resource Identifier (URI), as described in Section 2.7 of [RFC7230]. When a client constructs an HTTP/1.1 request message, it sends the target URI in one of various forms, as defined in (Section 5.3 of [RFC7230]). When a request is received, the server reconstructs an effective request URI for the target resource (Section 5.5 of [RFC7230]). One design goal of HTTP is to separate resource identification from request semantics, which is made possible by vesting the request semantics in the request method (Section 4) and a few request-modifying header fields (Section 5). If there is a conflict between the method semantics and any semantic implied by the URI itself, as described in Section 4.2.1, the method semantics take precedence.

So in my understand 404 status code should not be used on successful GET request with empty result.(example: a list with no result for specific filter)

If you're looking to put line breaks into the tooltip that appears on mouseover, there's no reliable crossbrowser way to do that. You'd have to fall back to one of the many Javascript tooltip code samples

Cookie-Based Authentication

Cookies based Authentication works normally in these 4 steps-

1. The user provides a username and password in the login form and clicks Log In.
2. After the request is made, the server validate the user on the backend by querying in the database. If the request is valid, it will create a session by using the user information fetched from the database and store them, for each session a unique id called session Id is created ,by default session Id is will be given to client through the Browser.

3. Browser will submit this session Id on each subsequent requests, the session ID is verified against the database, based on this session id website will identify the session belonging to which client and then give access the request.

4. Once a user logs out of the app, the session is destroyed both client-side and server-side.

A few points:

1) "DataBind()" is only for web apps (not windows apps).

2) Your code looks very 'JAVAish' (not a bad thing, just an observation).

Try this:

mnuActionLanguage.ComboBox.DataSource = languages;

If that doesn't work... then I'm assuming that your datasource is being stepped on somewhere else in the code.

Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7.

In versions pre-G++ 4.7, you'll have to use -std=c++0x, for more recent versions you can use -std=c++11.

Simply use

JSON.stringify(obj)

Example

var args_string = JSON.stringify(obj);
console.log(args_string);

Or

alert(args_string);

Also, note in javascript functions are considered as objects.

As an extra note :

Actually you can assign new property like this and access it console.log or display it in alert

foo.moo = "stackoverflow";
console.log(foo.moo);
alert(foo.moo);

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

Your code is correct. Kindly mark small correction.

A correct way to do basic auth in Python3 urllib.request with certificate validation follows.

Note that certifi is not mandatory. You can use your OS bundle (likely *nix only) or distribute Mozilla's CA Bundle yourself. Or if the hosts you communicate with are just a few, concatenate CA file yourself from the hosts' CAs, which can reduce the risk of MitM attack caused by another corrupt CA.

#!/usr/bin/env python3


import urllib.request
import ssl

import certifi


context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_REQUIRED
context.load_verify_locations(certifi.where())
httpsHandler = urllib.request.HTTPSHandler(context = context)

manager = urllib.request.HTTPPasswordMgrWithDefaultRealm()
manager.add_password(None, 'https://domain.com/', 'username', 'password')
authHandler = urllib.request.HTTPBasicAuthHandler(manager)

opener = urllib.request.build_opener(httpsHandler, authHandler)

# Used globally for all urllib.request requests.
# If it doesn't fit your design, use opener directly.
urllib.request.install_opener(opener)

response = urllib.request.urlopen('https://domain.com/some/path')
print(response.read())

This method works for Excel 2016, and calculates on cell value, so can be used on formula arrays (i.e. it will ignore blank cells that contain a formula).

• Highlight the range.
• Home > Conditional Formatting > New Rule > Use a Formula.
• Enter "=LEN(#)>0" (where '#' is the upper-left-most cell in your range).
• Alter the formatting to suit your preference.

Note: Len(#)>0 be altered to only select cell values above a certain length.

Note 2: '#' must not be an absolute reference (i.e. shouldn't contain '$').

You want to use:

git checkout --ours foo/bar.java
git add foo/bar.java

If you rebase a branch feature_x against main (i.e. running git rebase main while on branch feature_x), during rebasing ours refers to main and theirs to feature_x.

As pointed out in the git-rebase docs:

Note that a rebase merge works by replaying each commit from the working branch on top of the branch. Because of this, when a merge conflict happens, the side reported as ours is the so-far rebased series, starting with <upstream>, and theirs is the working branch. In other words, the sides are swapped.

You need to install django rest framework using pip3 (pip for python 3):

pip3 install djangorestframework

Instructions on how to install pip3 can be found here

A simple way to do this is

compile fileTree(include: ['*.jar'], dir: 'libs')

it will compile all the .jar files in your libs directory in App.

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

http://127.0.0.1:3000/api/v1/tours/5/10
//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987

Not spectacular different than the answers already given, but more generic is :

sortArrayOfObjects = (arr, key) => {
    return arr.sort((a, b) => {
        return a[key] - b[key];
    });
};

sortArrayOfObjects(yourArray, "distance");

For Java users write this line above your setContentView(R.layout.activity_main);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE);

For kotlin users

window.setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE)

$(this).find(".bgHeaderH2").html();

or

$(this).find(".bgHeaderH2").text();

I downloaded and installed the JDK 1.7 from Oracle. In the console / in Terminal Java 7 works fine.

When I start a Java program (like Eclipse) via the GUI, I get:

To open "Eclipse.app" you need a Java SE 6 runtime. Would you like to install one now?

Because I did not want to install old Java version, I used the following workaround:

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

C++14 lets you do static constexpr auto pi = acos(-1);

You need to use regular expressions in your custom validator. For example, here's the code that allows only 9 digits in the input fields:

function ssnValidator(control: FormControl): {[key: string]: any} {
  const value: string = control.value || '';
  const valid = value.match(/^\d{9}$/);
  return valid ? null : {ssn: true};
}

Take a look at a sample app here:

https://github.com/Farata/angular2typescript/tree/master/Angular4/form-samples/src/app/reactive-validator

If you use jQuery and would need an inline solution, this would work very well;

<a href="#" onclick="$(this).closest('form').submit();">submit form</a>

Also, you might want to replace

<a href="#">text</a>

with

<a href="javascript:void(0);">text</a>

so the user does not scroll to the top of your page when clicking the link.

For some people, the accepted answer is not working, I found this other answer and it is working for me: How can I pass a parameter to a setTimeout() callback?

var hello = "Hello World";
setTimeout(alert, 1000, hello); 

'hello' is the parameter being passed, you can pass all the parameters after the timeout time. Thanks to @Fabio Phms for the answer.

Another variation you can try is(expanding @mnel's answer) if you have many temp'x'.

here "n" could be the number of temp variables present

rm(list = c(paste("temp",c(1:n),sep="")))

I have been load testing a server application (on linux) by using a test program with 20 threads.

In 959,000 connect / close cycles I had 44,000 failed connections and many thousands of sockets in TIME_WAIT.

I set SO_LINGER to 0 before the close call and in subsequent runs of the test program had no connect failures and less than 20 sockets in TIME_WAIT.

Firefox 3 doesn't seem to have a problem with huge numbers.

1e+200 * 1e+100 will calculate fine to 1e+300.

Safari seem to have no problem with it as well. (For the record, this is on a Mac if anyone else decides to test this.)

Unless I lost my brain at this time of day, this is way bigger than a 64-bit integer.

To do this with user input:

public static void getPow(){
    Scanner sc = new Scanner(System.in);
    System.out.println("Enter first integer: ");    // 3
    int first = sc.nextInt();
    System.out.println("Enter second integer: ");    // 2
    int second = sc.nextInt();
    System.out.println(first + " to the power of " + second + " is " + 
        (int) Math.pow(first, second));    // outputs 9

I'm not a huge fan of the [EDIT: original versions of the] existing answers, because disabling security checks should be a last resort, not the first solution offered. Even though you cannot trust self-signed certificates on first receipt without some additional method of verification, using the certificate for subsequent git operations at least makes life a lot harder for attacks which only occur after you have downloaded the certificate. In other words, if the certificate you downloaded is genuine, then you're good from that point onwards. In contrast, if you simply disable verification then you are wide open to any kind of man-in-the-middle attack at any point.

To give a specific example: the famous repo.or.cz repository provides a self-signed certificate. I can download that file, place it somewhere like /etc/ssl/certs, and then do:

# Initial clone
GIT_SSL_CAINFO=/etc/ssl/certs/rorcz_root_cert.pem \
    git clone https://repo.or.cz/org-mode.git

# Ensure all future interactions with origin remote also work
cd org-mode
git config http.sslCAInfo /etc/ssl/certs/rorcz_root_cert.pem

Note that using local git config here (i.e. without --global) means that this self-signed certificate is only trusted for this particular repository, which is nice. It's also nicer than using GIT_SSL_CAPATH since it eliminates the risk of git doing the verification via a different Certificate Authority which could potentially be compromised.

A straight forward way, that iterates through all the chidren of the contenteditable div until it hits the endContainer. Then I add the end container offset and we have the character index. Should work with any number of nestings. uses recursion.

Note: requires a poly fill for ie to support Element.closest('div[contenteditable]')

https://codepen.io/alockwood05/pen/vMpdmZ

function caretPositionIndex() {
    const range = window.getSelection().getRangeAt(0);
    const { endContainer, endOffset } = range;

    // get contenteditableDiv from our endContainer node
    let contenteditableDiv;
    const contenteditableSelector = "div[contenteditable]";
    switch (endContainer.nodeType) {
      case Node.TEXT_NODE:
        contenteditableDiv = endContainer.parentElement.closest(contenteditableSelector);
        break;
      case Node.ELEMENT_NODE:
        contenteditableDiv = endContainer.closest(contenteditableSelector);
        break;
    }
    if (!contenteditableDiv) return '';


    const countBeforeEnd = countUntilEndContainer(contenteditableDiv, endContainer);
    if (countBeforeEnd.error ) return null;
    return countBeforeEnd.count + endOffset;

    function countUntilEndContainer(parent, endNode, countingState = {count: 0}) {
      for (let node of parent.childNodes) {
        if (countingState.done) break;
        if (node === endNode) {
          countingState.done = true;
          return countingState;
        }
        if (node.nodeType === Node.TEXT_NODE) {
          countingState.count += node.length;
        } else if (node.nodeType === Node.ELEMENT_NODE) {
          countUntilEndContainer(node, endNode, countingState);
        } else {
          countingState.error = true;
        }
      }
      return countingState;
    }
  }
