In IntelliJ IDEA, you can switch the selection mode with Alt + Shift + Insert combination. You can also column select by keeping the middle mouse button (i.e. the scroll wheel button) pressed and dragging.

Why does the error mention tuples?

Others have explained that the problem was the missing ,, but the final mystery is why does the error message talk about tuples?

The reason is that your:

["pennies", '2.5', '50.0', '.01'] 
["nickles", '5.0', '40.0', '.05']

can be reduced to:

[][1, 2]

as mentioned by 6502 with the same error.

But then __getitem__, which deals with [] resolution, converts object[1, 2] to a tuple:

class C(object):
    def __getitem__(self, k):
        return k

# Single argument is passed directly.
assert C()[0] == 0

# Multiple indices generate a tuple.
assert C()[0, 1] == (0, 1)

and the implementation of __getitem__ for the list built-in class cannot deal with tuple arguments like that.

More examples of __getitem__ action at: https://stackoverflow.com/a/33086813/895245

If you are using PyQt, then for normal work, you should add "shell":"true" value, this looks like:

{
  "cmd": ["c:/Python32/python.exe", "-u", "$file"],
  "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
  "selector": "source.python",
  "shell":"true"
}

<style="text-decoration: none">

The above code will be enough.Just paste this into the link you want to remove underline from.

You can easily draw simple svgs onto a canvas by:

1. Assigning the source of the svg to an image in base64 format
2. Drawing the image onto a canvas

Note: The only drawback of the method is that it cannot draw images embedded in the svg. (see demo)

Demonstration:

(Note that the embedded image is only visible in the svg)

var svg = document.querySelector('svg');_x000D_
var img = document.querySelector('img');_x000D_
var canvas = document.querySelector('canvas');_x000D_
_x000D_
// get svg data_x000D_
var xml = new XMLSerializer().serializeToString(svg);_x000D_
_x000D_
// make it base64_x000D_
var svg64 = btoa(xml);_x000D_
var b64Start = 'data:image/svg+xml;base64,';_x000D_
_x000D_
// prepend a "header"_x000D_
var image64 = b64Start + svg64;_x000D_
_x000D_
// set it as the source of the img element_x000D_
img.src = image64;_x000D_
_x000D_
// draw the image onto the canvas_x000D_
canvas.getContext('2d').drawImage(img, 0, 0);

svg, img, canvas {_x000D_
  display: block;_x000D_
}

SVG_x000D_
_x000D_
<svg height="40">_x000D_
  <rect width="40" height="40" style="fill:rgb(255,0,255);" />_x000D_
  <image xlink:href="https://en.gravatar.com/userimage/16084558/1a38852cf33713b48da096c8dc72c338.png?size=20" height="20px" width="20px" x="10" y="10"></image>_x000D_

So I did mine with the full styling and border colors like this:

new OutlineButton(
    shape: StadiumBorder(),
    textColor: Colors.blue,
    child: Text('Button Text'),
    borderSide: BorderSide(
        color: Colors.blue, style: BorderStyle.solid, 
        width: 1),
    onPressed: () {},
)

If you want to detect class change, best way is to use Mutation Observers, which gives you complete control over any attribute change. However you need to define listener yourself, and append it to element you are listening. Good thing is that you don't need to trigger anything manually once listener is appended.

$(function() {
(function($) {
    var MutationObserver = window.MutationObserver || window.WebKitMutationObserver || window.MozMutationObserver;

    $.fn.attrchange = function(callback) {
        if (MutationObserver) {
            var options = {
                subtree: false,
                attributes: true
            };

            var observer = new MutationObserver(function(mutations) {
                mutations.forEach(function(e) {
                    callback.call(e.target, e.attributeName);
                });
            });

            return this.each(function() {
                observer.observe(this, options);
            });

        }
    }
})(jQuery);

//Now you need to append event listener
$('body *').attrchange(function(attrName) {

    if(attrName=='class'){
            alert('class changed');
    }else if(attrName=='id'){
            alert('id changed');
    }else{
        //OTHER ATTR CHANGED
    }

});
});

In this example event listener is appended to every element, but you don't want that in most cases (save memory). Append this "attrchange" listener to element you want observe.

This will give you a callable function when the user presses the return key.

fun EditText.setLineBreakListener(onLineBreak: () -> Unit) {
    val lineBreak = "\n"
    doOnTextChanged { text, _, _, _ ->
        val currentText = text.toString()

        // Check if text contains a line break
        if (currentText.contains(lineBreak)) {

            // Uncommenting the lines below will remove the line break from the string
            // and set the cursor back to the end of the line

            // val cleanedString = currentText.replace(lineBreak, "")
            // setText(cleanedString)
            // setSelection(cleanedString.length)

            onLineBreak()
        }
    }
}

Usage

editText.setLineBreakListener {
    doSomething()
}

Use CSS background-image in a case of multiple skins or versions of design. Javascript can be used to dynamically change a class of an element, which will force it to render a different image. With an IMG tag, it may be more tricky.

Create a plain text file (using notepad) and type the exact line you would use to run your Java file with the command prompt. Then change the extension to .bat and you're done.

Double clicking on this file would run your java program.

I reccommend one file for javac, one for java so you can troubleshoot if anything is wrong.

• Make sure java is in your path, too.. IE typing java in a Dos windows when in your java workspace should bring up the java version message. If java is not in your path the batch file won't work unless you use absolut path to the java binary.

I was looking for same thing but in number, means from integer xx hour, xx minutes and AM/PM to 24 hour format xx hour and xx minutes, so here what i have done:

private static final int AM = 0;
private static final int PM = 1;
/**
   * Based on concept: day start from 00:00AM and ends at 11:59PM, 
   * afternoon 12 is 12PM, 12:xxAM is basically 00:xxAM
   * @param hour12Format
   * @param amPm
   * @return
   */
  private int get24FormatHour(int hour12Format,int amPm){
    if(hour12Format==12 && amPm==AM){
      hour12Format=0;
    }
    if(amPm == PM && hour12Format!=12){
      hour12Format+=12;
    }
    return hour12Format;
  }`

    private int minutesTillMidnight(int hour12Format,int minutes, int amPm){
        int hour24Format=get24FormatHour(hour12Format,amPm);
        System.out.println("24 Format :"+hour24Format+":"+minutes); 
        return (hour24Format*60)+minutes;
      }

If you rotate point (px, py) around point (ox, oy) by angle theta you'll get:

p'x = cos(theta) * (px-ox) - sin(theta) * (py-oy) + ox

p'y = sin(theta) * (px-ox) + cos(theta) * (py-oy) + oy

this is an easy way to rotate a point in 2D.

I came here to find out how to make VSCode (Mac OS) create a new window when a file or folder is opened and VSCode is already running. The same as GitHub Atom does. The answers above haven't answered my query, bit I've found answer myself so will share.

Setting: window.openFilesInNewWindow - if set to on, files will open in a new window. window.openFoldersInNewWindow - if set to on, folders will open in a new window.

Bonus to make it behave like Atom: Set window.newWindowDimensions to maximised.

Using " is the way to do it. I tried your second code snippet, and it works in both Firefox and Internet Explorer.

As of October 2014:

For latest remote version:

npm view <module_name> version  

Note, version is singular.

If you'd like to see all available (remote) versions, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

To get the version you actually have locally you could use:

npm list --depth=0 | grep <module_name>

Note, even with package.json declaring your versions, the installed version might actually differ slightly - for instance if tilda was used in the version declaration

Should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

Add this to an htaccess file (and see edit notes added below):

<IfModule mod_php5.c>
   php_value post_max_size 200M
   php_value upload_max_filesize 200M
   php_value memory_limit 300M
   php_value max_execution_time 259200
   php_value max_input_time 259200
   php_value session.gc_maxlifetime 1200

2021 EDIT:

As PHP and Apache evolve and grow, I think it is important for me to take a moment to mention a few things to consider and possible "gotchas" to consider:

• PHP can be run as a module or as CGI. It is not recommended to run as CGI as it creates a lot of opportunities for attack vectors [Read More]. Running as a module (the safer option) will trigger the settings to be used if the specific module from <IfModule is loaded.
• The answer indicates to write mod_php5.c in the first line. If you are using PHP 7, you would replace that with mod_php7.c.
• Sometimes after you make changes to your .htaccess file, restarting Apache or NGINX will not work. The most common reason for this is you are running PHP-FPM, which runs as a separate process. You need to restart that as well.
• Remember these are settings that are normally defined in your php.ini config file(s). This method is usually only useful in the event your hosting provider does not give you access to change those files. In circumstances where you can edit the PHP configuration, it is recommended that you apply these settings there.
• Finally, it's important to note that not all php.ini settings can be configured via an .htaccess file. A file list of php.ini directives can be found here, and the only ones you can change are the ones in the changeable column with the modes PHP_INI_ALL or PHP_INI_PERDIR.

When you apply your own function, there is not automatic exclusions of non-numeric columns. This is slower, though, than the application of .sum() to the groupby

In [8]: df.groupby('A').apply(lambda x: x.sum())

sum by default concatenates

In [9]: df.groupby('A')['C'].apply(lambda x: x.sum())

A

You can do pretty much what you want

In [11]: df.groupby('A')['C'].apply(lambda x: "{%s}" % ', '.join(x))
Out[11]:

Doing this on a whole frame, one group at a time. Key is to return a Series

def f(x):
     return Series(dict(A = x['A'].sum(), 
                        B = x['B'].sum(), 
                        C = "{%s}" % ', '.join(x['C'])))

Using plain javascript:

In jQuery:

I believe TLSV1_ALERT_PROTOCOL_VERSION is alerting you that the server doesn't want to talk TLS v1.0 to you. Try to specify TLS v1.2 only by sticking in these lines:

import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)

# Create HTTPS connection
c = HTTPSConnection("0.0.0.0", context=context)

Note, you may need sufficiently new versions of Python (2.7.9+ perhaps?) and possibly OpenSSL (I have "OpenSSL 1.0.2k 26 Jan 2017" and the above seems to work, YMMV)

To add color to an input, Use the following css code:

input{

}

For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:

composer require phpseclib/phpseclib

Next, simply use it as follows:

use phpseclib\Net\SSH2;

// Within a controller for example:
$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
    // Login failed, do something
}

$return_value = $ssh->exec('command');

Using constraints layout

1. Add a Guideline
2. Set the percentage to 50%
3. Constrain your view to the Guideline and the parent.

If you are having trouble changing it to a percentage, then see this answer.

This is more or less lifted from the Matlab manual; I've only got passing experience...

function my_output = wave ( a, b, n, k, T, f, flag, varargin )
  optargin = numel(varargin);
  fTrue = inline('0');
  if optargin > 0
    fTrue = varargin{1};
  end
  % code ...
end

From what I know

3 one-liners

1. a = 10 if <condition>

example:

a = 10 if true # a = 10
b = 10 if false # b = nil

2. a = 10 unless <condition>

example:

a = 10 unless false # a = 10
b = 10 unless true # b = nil

3. a = <condition> ? <a> : <b>

example:

a = true ? 10 : 100 # a = 10
a = false ? 10 : 100 # a = 100

I hope it helps.

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

In my case, I need to dump the sql result into a file on the client side. This is the most typical use case to off load data from the database. In many situations, you don't have access to the server or don't want to write your result to the server.

mysql -h hostname -u username -ppwd -e "mysql simple sql statement that last for less than a line" DATABASE_NAME > outputfile_on_the.client

The problem comes when you have a complicated query that last for several lines; you cannot use the command line to dump the result to a file easily. In such cases, you can put your complicated query into a file, such as longquery_file.sql, then execute the command.

mysql -h hn -u un -ppwd < longquery_file.sql DBNAME > output.txt

This worked for me. The only difficulty with me is the tab character; sometimes I use for group_cancat(foo SEPARATOR 0x09) will be written as '\t' in the output file. The 0x09 character is ASCII TAB. But this problem is not particular to the way we dump sql results to file. It may be related to my pager. Let me know when you find an answer to this problem. I will update this post.

If you want logs in a separate file other than the console: Double click on the server--> Open Launch Configuration--> Arguments --> add -Dlog.dir = "Path where you want to store this file" and restart the server.

Tip: Make sure that the server is not running when you are trying to add the argument. You should have log4j or similar logging framework in place.

Also check to see if you are missing the www in the url which was on my case

i was testing on http://www.mywebsite.com and in the facebook app i had set http://mywebsite.com

Can do the following

PRINT dbo.[FunctionName] ( [Parameter/Argument] )

E.g.:

PRINT dbo.StringSplit('77,54')

@HostListener is a decorator for the callback/event handler method, so remove the ; at the end of this line:

@HostListener('click', ['$event.target']);

Here's a working plunker that I generated by copying the code from the API docs, but I put the onClick() method on the same line for clarity:

import {Component, HostListener, Directive} from 'angular2/core';

@Directive({selector: 'button[counting]'})
class CountClicks {
  numberOfClicks = 0;
  @HostListener('click', ['$event.target']) onClick(btn) {
    console.log("button", btn, "number of clicks:", this.numberOfClicks++);
  }
}
@Component({
  selector: 'my-app',
  template: `<button counting>Increment</button>`,
  directives: [CountClicks]
})
export class AppComponent {
  constructor() { console.clear(); }
}

Host binding can also be used to listen to global events:

To listen to global events, a target must be added to the event name. The target can be window, document or body (reference)

@HostListener('document:keyup', ['$event'])
handleKeyboardEvent(kbdEvent: KeyboardEvent) { ... }

You should specially have a look on your global or static data (long living data).

When this data grows without restriction, you can also get troubles in Python.

The garbage collector can only collect data, that is not referenced any more. But your static data can hookup data elements that should be freed.

Another problem can be memory cycles, but at least in theory the Garbage collector should find and eliminate cycles -- at least as long as they are not hooked on some long living data.

What kinds of long living data are specially troublesome? Have a good look on any lists and dictionaries -- they can grow without any limit. In dictionaries you might even don't see the trouble coming since when you access dicts, the number of keys in the dictionary might not be of big visibility to you ...

An enum declares a set of ordered values - the typedef just adds a handy name to this. The 1st element is 0 etc.

typedef enum {
Monday=1,
...
} WORKDAYS;

WORKDAYS today = Monday;

The above is just an enumeration of shapeType tags.

You can use $(window).resize() to detect if the viewport is resized.

jQuery does not have any function to consistently detect the correctly width and height of the viewport[1] when there is a scroll bar present.

I found a solution that uses the Modernizr library and specifically the mq function which opens media queries for javascript.

Here is my solution:

// A function for detecting the viewport minimum width.
// You could use a similar function for minimum height if you wish.
var min_width;
if (Modernizr.mq('(min-width: 0px)')) {
    // Browsers that support media queries
    min_width = function (width) {
        return Modernizr.mq('(min-width: ' + width + ')');
    };
}
else {
    // Fallback for browsers that does not support media queries
    min_width = function (width) {
        return $(window).width() >= width;
    };
}

var resize = function() {
    if (min_width('768px')) {
        // Do some magic
    }
};

$(window).resize(resize);
resize();

My answer will probably not help resizing a iframe to 100% viewport width with a margin on each side, but I hope it will provide solace for webdevelopers frustrated with browser incoherence of javascript viewport width and height calculation.

Maybe this could help with regards to the iframe:

$('iframe').css('width', '100%').wrap('<div style="margin:2em"></div>');

[1] You can use $(window).width() and $(window).height() to get a number which will be correct in some browsers, but incorrect in others. In those browsers you can try to use window.innerWidth and window.innerHeight to get the correct width and height, but i would advice against this method because it would rely on user agent sniffing.

Usually the different browsers are inconsistent about whether or not they include the scrollbar as part of the window width and height.

Note: Both $(window).width() and window.innerWidth vary between operating systems using the same browser. See: https://github.com/eddiemachado/bones/issues/468#issuecomment-23626238

Surely using array_map and if using a container implementing ArrayAccess to derive objects is just a smarter, semantic way to go about this?

Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.

For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN() clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.

<?php

$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);

vs

<?php

$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
    $arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);

If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr you could always $arr = array_map and be explicit.

I had a similar issue, but in my case, it was my CSS file.

I had loaded my CSS file before the JQuery library, since my jquery function was interaction with my css file, my jquery function wasn't working. I found this weird, but when I loaded the CSS file after loading the JQuery library, it worked.

This might not be directly related to the Question, but it may help others who might be facing a similar problem.

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

DECLARE
   PROD_ROW_ID   VARCHAR (10) := NULL;
   VIS_ROW_ID    NUMBER;
   DSC           VARCHAR (512);

April 2020 Answer

In Chromium 81+, I have found the answer to be: go to chrome://extensions/, click to enable Developer Mode on the top right corner, then drag and drop your .user.js script.

From the Sonatype doc:

The answer to this question depends on your own perspective. The great majority of Maven users are going to call Maven a “build tool”: a tool used to build deployable artifacts from source code. Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is focused solely on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team.

I'd strongly recommend looking at the Sonatype doc and spending some time looking at the available plugins to understand the power of Maven.

Very briefly, it operates at a higher conceptual level than (say) Ant. With Ant, you'd specify the set of files and resources that you want to build, then specify how you want them jarred together, and specify the order that should occur in (clean/compile/jar). With Maven this is all implicit. Maven expects to find your files in particular places, and will work automatically with that. Consequently setting up a project with Maven can be a lot simpler, but you have to play by Maven's rules!

The only things I can think of are

1. including files
2. replacing elements within files using preg_match_all
3. using assigned variables

I have recently been using str_replace and setting text in the HTML portion like so

{{TEXT_TO_REPLACE}}

using file_get_contents() you can grab html data and then organise it how you like.

here is a demo

myReplacementCodeFunction(){
  $text = '<img src="'.$row['name'].'" />'; 
  $text .= "<div>".$row['name']."</div>";
  $text .= "<div>".$row['title']."</div>";
  $text .= "<div>".$row['description']."</div>";
  $text .= "<div>".$row['link']."</div>";
  $text .= "<br />";
  return $text;
}

$htmlContents = file_get_contents("myhtmlfile.html");
$htmlContents = str_replace("{{TEXT_TO_REPLACE}}", myReplacementCodeFunction(), $htmlContents);
echo $htmlContents;

and now a demo html file:

<html>
<head>
   <style type="text/css">
      body{background:#666666;}
      div{border:1px solid red;}
   </style>
  </head>
  <body>
    {{TEXT_TO_REPLACE}}
  </body>
</html>

A common property of Java Web-apps is that they usually use servlets which usually means the web server also runs Java. This contributes to the perceived complexity, IMHO. But you can build Java apps in the traditional Unix-style of "do one thing and do it well" without having performance suffer.

You can also use SCGI, it is a lot simpler than FastCGI. I'd try that first. But if it doesn't work out:

How to write a FastCGI application in Java

1. Make an empty working directory and enter it
2. Download the FastCGI devkit: wget --quiet --recursive --no-parent --accept=java --no-directories --no-host-directories "http://www.fastcgi.com/devkit/java/"
3. mkdir -p com/fastcgi
4. mv *.java com/fastcgi

5. Now you need to apply a tiny patch to the devkit (replace operator == with <= on line 175 or use this script to do it):

   echo -e "175c\nif (count <= 0) {\n.\nw\nn\nq" | ed -s com/fastcgi/FCGIInputStream.java

6. Create a test app, TinyFCGI.java (source below)
7. Compile everything: javac **/*.java (** will probably only work in zsh)
8. Start the FastCGI server: java -DFCGI_PORT=9884 TinyFCGI (leave it running in the background)

9. Now set up e.g. Apache to use the server:

   • Using Apache 2.4, you can use mod_proxy_fcgi like this:
     1. Using Ubuntu, upgrade to Apache 2.4 using i.e. this PPA
     2. Enable the mod: sudo a2enmod proxy_fcgi
     3. Create /etc/apache2/conf-enabled/your_site.conf with the content below
     4. Restart Apache: sudo apache2ctl restart

10. Now you can access the webapp at http://localhost/your_site

11. Benchmark results below

TinyFCGI.java

import com.fastcgi.FCGIInterface;
import java.io.*;
import static java.lang.System.out;

class TinyFCGI {
    public static void main (String args[]) {
        int count = 0;
        FCGIInterface fcgiinterface = new FCGIInterface();
        while(fcgiinterface.FCGIaccept() >= 0) {
            count++;
            out.println("Content-type: text/html\n\n");
            out.println("<html>");
            out.println(
                "<head><TITLE>FastCGI-Hello Java stdio</TITLE></head>");
            out.println("<body>");
            out.println("<H3>FastCGI-HelloJava stdio</H3>");
            out.println("request number " + count +
                               " running on host "
                               + System.getProperty("SERVER_NAME"));
            out.println("</body>");
            out.println("</html>");

The Java keyword list specifies the goto keyword, but it is marked as "not used".

This was probably done in case it were to be added to a later version of Java.

If goto weren't on the list, and it were added to the language later on, existing code that used the word goto as an identifier (variable name, method name, etcetera) would break. But because goto is a keyword, such code will not even compile in the present, and it remains possible to make it actually do something later on, without breaking existing code.

This is how to change it :

Step 1 :

Open a Terminal / CMD As Administrator (Right-click on cmd and click "Run as Administrator")

Step 2:

type in " set ANDROID_SDK_ROOT=E:\Android\sdk\ " (type it without the quotes and replace "E:\Android\sdk" with your actual sdk file path location - Mine was : C:\Users\YOUR_ACCOUNT\AppData\Local\Android\Sdk

step 3:

Press "Enter" and i noticed nothing happened

Step 4:

Build your app again and it should reflect your file path. For me it doisplayed as :

Preparing Firebase on Android Checking Java JDK and Android SDK versions ANDROID_SDK_ROOT=C:\Users\Kurt\AppData\Local\Android\Sdk (recommended setting) ANDROID_HOME=C:\Users\Kurt\AppData\Local\Android\Sdk (DEPRECATED) Subproject Path: CordovaLib Subproject Path: app

I got that info from this site :

https://developer.android.com/studio/command-line/variables#android_sdk_root

Check it out for more information Have Fun!!

I'm late to the party, but this solution worked for me quite well. Based on this library, you can use a function lik this - setting the image, quality, max-width, and output format (jepg,png):

function compress(source_img_obj, quality, maxWidth, output_format){
    var mime_type = "image/jpeg";
    if(typeof output_format !== "undefined" && output_format=="png"){
        mime_type = "image/png";
    }

    maxWidth = maxWidth || 1000;
    var natW = source_img_obj.naturalWidth;
    var natH = source_img_obj.naturalHeight;
    var ratio = natH / natW;
    if (natW > maxWidth) {
        natW = maxWidth;
        natH = ratio * maxWidth;
    }

    var cvs = document.createElement('canvas');
    cvs.width = natW;
    cvs.height = natH;

    var ctx = cvs.getContext("2d").drawImage(source_img_obj, 0, 0, natW, natH);
    var newImageData = cvs.toDataURL(mime_type, quality/100);
    var result_image_obj = new Image();
    result_image_obj.src = newImageData;
    return result_image_obj;
}

Using the query parameter won't work, Google will try to approximate the location.

The location I want : http://maps.google.com/maps?ll=43.7920533400153,6.37761393942265

The approximate location (west of the actual location) : http://maps.google.com/?q=43.7920533400153,6.37761393942265

Following from Ryan's answer, I think that the interface you are looking for is defined as follows:

interface Param {
    title: string;
    callback: () => void;
}

Its a very old question but I think it will help newbies line me who are learning python. If you have Python 3.4 or above, the pathlib library comes with the default distribution.

To use it, you just pass a path or filename into a new Path() object using forward slashes and it handles the rest. To indicate that the path is a raw string, put r in front of the string with your actual path.

For example,

from pathlib import Path

dataFolder = Path(r'D:\Desktop dump\example.txt')

I did it for Windows too. Full answer here

For Windows: Filemon from SysInternals will show you what files are being accessed.

Remember to set your filters so you are not overwhelmed by the chatty file system traffic.

Added: Filemon does not work with newer Windows versions, so you might have to use Process Monitor.

From the AWS documentation:

Amazon SNS allows applications to send time-critical messages to multiple subscribers through a “push” mechanism, eliminating the need to periodically check or “poll” for updates.

Amazon SQS is a message queue service used by distributed applications to exchange messages through a polling model, and can be used to decouple sending and receiving components—without requiring each component to be concurrently available.

Fanout to Amazon SQS queues

I've solved the endless fight with Google Chrome with the use of random characters. When you always render autocomplete with random string, it will never remember anything.

<input name="name" type="text" autocomplete="rutjfkde">

Hope that it will help to other people.

Rahul's answer gives me an error: You seem to be trying to send a WhatsApp message to a phone number that is not registered with WhatsApp..., even though I'm sending it to a registered WhatsApp number.

This, however works:

<li><a href="intent:0123456789#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end"><i class="fa fa-whatsapp"></i>+237 655 421 621</li>

To insert a sleep command you can use Thread.sleep(2000). So the code would be:

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
Iterator<Integer> myListIterator = someList.iterator(); 
while (myListIterator.hasNext()) {
    Integer coord = myListIterator.next();    
    System.out.println(coord);
    Thread.Sleep(2000);
}

This would output: 10 20 30 40 50

If you want the numbers after each other you could use: System.out.print(coord +" " ); and if you want to repeat the section you can put it in another while loop.

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
    Iterator<Integer> myListIterator = someList.iterator(); 
    while (myListIterator.hasNext()) {
        Integer coord = myListIterator.next();    
        System.out.print(coord + " ");
        Thread.Sleep(2000);
    }
}

This would output: 10 20 30 40 50 10 20 30 40 50 ... and never stop until you kill the program.

Edit: You do have to put the sleep command in a try catch block

Just add this one-line class in your CSS, and use the bootstrap label component.

.label-as-badge {
    border-radius: 1em;
}

Compare this label and badge side by side:

<span class="label label-default label-as-badge">hello</span>
<span class="badge">world</span>

They appear the same. But in the CSS, label uses em so it scales nicely, and it still has all the "-color" classes. So the label will scale to bigger font sizes better, and can be colored with label-success, label-warning, etc. Here are two examples:

<span class="label label-success label-as-badge">Yay! Rah!</span>

Or where things are bigger:

<div style="font-size: 36px"><!-- pretend an enclosing class has big font size -->
    <span class="label label-success label-as-badge">Yay! Rah!</span>
</div>

11/16/2015: Looking at how we'll do this in Bootstrap 4

Looks like .badge classes are completely gone. But there's a built-in .label-pill class (here) that looks like what we want.

.label-pill {
  padding-right: .6em;
  padding-left: .6em;
  border-radius: 10rem;
}

In use it looks like this:

<span class="label label-pill label-default">Default</span>
<span class="label label-pill label-primary">Primary</span>
<span class="label label-pill label-success">Success</span>
<span class="label label-pill label-info">Info</span>
<span class="label label-pill label-warning">Warning</span>
<span class="label label-pill label-danger">Danger</span>

11/04/2014: Here's an update on why cross-pollinating alert classes with .badge is not so great. I think this picture sums it up:

Those alert classes were not designed to go with badges. It renders them with a "hint" of the intended colors, but in the end consistency is thrown out the window and readability is questionable. Those alert-hacked badges are not visually cohesive.

The .label-as-badge solution is only extending the bootstrap design. We are keeping intact all the decision making made by the bootstrap designers, namely the consideration they gave for readability and cohesion across all the possible colors, as well as the color choices themselves. The .label-as-badge class only adds rounded corners, and nothing else. There are no color definitions introduced. Thus, a single line of CSS.

Yep, it is easier to just hack away and drop in those .alert-xxxxx classes -- you don't have to add any lines of CSS. Or you could care more about the little things and add one line.

There are several methods you could use that exist in the System.IO namespace:

Directory.GetLogicalDrives() // Returns an array of strings like "c:\"
Path.GetInvalidFileNameChars() // Returns an array of characters that cannot be used in a file name
Path.GetInvalidPathChars() // Returns an array of characters that cannot be used in a path.

As suggested you could then do this:

bool IsValidFilename(string testName) {
    string regexString = "[" + Regex.Escape(Path.GetInvalidPathChars()) + "]";
    Regex containsABadCharacter = new Regex(regexString);
    if (containsABadCharacter.IsMatch(testName)) {
        return false;
    }

    // Check for drive
    string pathRoot = Path.GetPathRoot(testName);
    if (Directory.GetLogicalDrives().Contains(pathRoot)) {
        // etc
    }

    // other checks for UNC, drive-path format, etc

    return true;
}

Update: As of November 6, 2012, console.clear() is now available in Chrome Canary.

If you type clear() into the console it clears it.

I don't think there is a way to programmatically do it, as it could be misused. (console is cleared by some web page, end user can't access error information)

one possible workaround:

in the console type window.clear = clear, then you'll be able to use clear in any script on your page.

What I need is a function which prints an object (obj), but only if global variable verbose is true, else it does nothing.

I want to be able to change the global parameter "verbose" at any time. Simplicity and readability to me are of paramount importance. So I would proceed as the following lines indicate:

ak@HP2000:~$ python3
Python 3.4.3 (default, Oct 14 2015, 20:28:29) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> verbose = True
>>> def vprint(obj):
...     if verbose:
...         print(obj)
...     return
... 
>>> vprint('Norm and I')
Norm and I
>>> verbose = False
>>> vprint('I and Norm')
>>> 

Global variable "verbose" can be set from the parameter list, too.

mkdir [-switch] foldername

-p is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.

From the man page:

-p, --parents no error if existing, make parent directories as needed

Example:

mkdir -p storage/framework/{sessions,views,cache}

This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.

Since ant 1.9.1 you can use a if:set condition : https://ant.apache.org/manual/ifunless.html

Use it in XML like

 <...CurrencyEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

You should edit 2 constant below for suitable for your project

private static String prefix = "VND ";
private static final int MAX_DECIMAL = 3;

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

Neither main() or void main() are standard C. The former is allowed as it has an implicit int return value, making it the same as int main(). The purpose of main's return value is to return an exit status to the operating system.

In standard C, the only valid signatures for main are:

int main(void)

and

int main(int argc, char **argv)

The form you're using: int main() is an old style declaration that indicates main takes an unspecified number of arguments. Don't use it - choose one of those above.

The focus only works if the window is focused.

Use ((JavascriptExecutor)webDriver).executeScript("window.focus();"); to be sure.

You may have to concatenate the % signs with your parameter, e.g.:

LIKE '%' || @query || '%'

Edit: Actually, that may not make any sense at all. I think I may have misunderstood your problem.

There's a problem with immediate asynchronous call of your function, because standard setTimeout/setInterval has a minimal timeout about several milliseconds even if you directly set it to 0. It caused by a browser specific work.

An example of code with a REAL zero delay wich works in Chrome, Safari, Opera

function setZeroTimeout(callback) {
var channel = new MessageChannel();
channel.port1.onmessage = callback;
channel.port2.postMessage('');
}

You can find more information here

And after the first manual call you can create an interval with your function.

Pass in the straight XML instead of a dictionary.

I recommend Charles Web Proxy

Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).

• SSL Proxying – view SSL requests and responses in plain text
• Bandwidth Throttling to simulate slower Internet connections including latency
• AJAX debugging – view XML and JSON requests and responses as a tree or as text
• AMF – view the contents of Flash Remoting / Flex Remoting messages as a tree
• Repeat requests to test back-end changes, Edit requests to test different inputs
• Breakpoints to intercept and edit requests or responses
• Validate recorded HTML, CSS and RSS/atom responses using the W3C validator

It's cross-platform, written in JAVA, and pretty good. Not nearly as overwhelming as Wireshark, and does a lot of the annoying stuff like setting up the proxies, etc. for you. The only bad part is that it costs money, $50 at that. Not cheap, but a useful tool.

Read more about Charles's features.

Maybe you been given sudo access to only some programs/paths? Then there is no way to do what you want. (unless you will hack it somehow)

If it is not the case then maybe you can write bash script:

cat > myscript.sh
#!/bin/sh
ls -hal /root/ > /root/test.out 

Press ctrl + d :

chmod a+x myscript.sh
sudo myscript.sh

Hope it help.

When running the python file, you would normally do this

python app.py

To avoid these messsages. Inside the CLI (Command Line Interface), run these commands.

export FLASK_APP=app.py
export FLASK_RUN_HOST=127.0.0.1
export FLASK_ENV=development
export FLASK_DEBUG=0
flask run

This should work perfectlly. :) :)

It appears that your format is incorrect:

If you want to share a locally created repository, or you want to take contributions from someone elses repository - if you want to interact in any way with a new repository, it's generally easiest to add it as a remote. You do that by running git remote add [alias] [url]. That adds [url] under a local remote named [alias].

#example
$ git remote
$ git remote add github [email protected]:schacon/hw.git
$ git remote -v

http://gitref.org/remotes/#remote

Simple copy & paste example with subqueries, Note, that both queries should return 1 row:

select
(select sum(items_1) from items_table_1 where ...)
-
(select count(items_2) from items_table_1 where ...) 

as difference

The short answer is, you have to loop.

It's simple: declare the widget variables (editText, textView, button etc.) in class but initialize it in onCreate after setContentView.

The problem is when you try to access a widget of a layout first you have to declare the layout. Declaring the layout is setContentView. And when you initialize the widget variable via findViewById you are accessing the id of the widget in the main layout in the setContentView.

I hope you get it!

An empty static class is appropriate. Consider using several classes, so that you end up with good groups of related constants, and not one giant Globals.cs file.

Additionally, for some int constants, consider the notation:

[Flags]
enum Foo
{
}

As this allows for treating the values like flags.

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.

Quick and dirty:

#!/usr/bin/perl -w

use strict;

open(FILE, "</tmp/yourfile.txt") || die "File not found";
my @lines = <FILE>;
close(FILE);

foreach(@lines) {
   $_ =~ s/<PREF>/ABCD/g;
}

open(FILE, ">/tmp/yourfile.txt") || die "File not found";
print FILE @lines;
close(FILE);

Perhaps it i a good idea not to write the result back to your original file; instead write it to a copy and check the result first.

Easy, you can use a Post request and submit your file as binary (byte array).

String url = "http://yourserver";
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath(),
        "yourfile");
try {
    HttpClient httpclient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost(url);

    InputStreamEntity reqEntity = new InputStreamEntity(
            new FileInputStream(file), -1);
    reqEntity.setContentType("binary/octet-stream");
    reqEntity.setChunked(true); // Send in multiple parts if needed
    httppost.setEntity(reqEntity);
    HttpResponse response = httpclient.execute(httppost);
    //Do something with response...

} catch (Exception e) {
    // show error
}

Try this in your css:

.a {
    transition: color 0.3s ease-in-out;
}
.a {
    color:turquoise;
}
.a:hover {
    color: #454545;
}

I cringe every time I use create_function() in php.

Parameters are a coma separated string, the whole function body in a string... Argh... I think they could not have made it uglier even if they tried.

Unfortunately, it is the only choice when creating a named function is not worth the trouble.

Your operator is incorrect. Should be if number >= 10000 and number <= 30000:. Additionally, Python has a shorthand for this sort of thing, if 10000 <= number <= 30000:.

$request->route()->getName();

If you are doing a lot of functionality based on scroll position, Scroll magic (http://scrollmagic.io/) is built entirely for this purpose.

It makes it easy to trigger JS based on when the user reaches certain elements when scrolling. It also integrates with the GSAP animation engine (https://greensock.com/) which is great for parallax scrolling websites

Idisposable is implement whenever you want a deterministic (confirmed) garbage collection.

class Users : IDisposable
    {
        ~Users()
        {
            Dispose(false);
        }

        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
            // This method will remove current object from garbage collector's queue 
            // and stop calling finilize method twice 
        }    

        public void Dispose(bool disposer)
        {
            if (disposer)
            {
                // dispose the managed objects
            }
            // dispose the unmanaged objects
        }
    }

When creating and using the Users class use "using" block to avoid explicitly calling dispose method:

using (Users _user = new Users())
            {
                // do user related work
            }

end of the using block created Users object will be disposed by implicit invoke of dispose method.

Here is another approach...

When I've got to the same problem, I didn't like the suggested solutions here. So, I've come up with another way: I've inserted a TextView in the XML file between the two fields I wanted to separate with two important fields:

1. visibility set to "GONE" (doesn't occupy any space..)

2. height is set to whatever I needed the separation to be.

   XML:
   ...//some view up here
   <TextView
       android:id="@+id/dialogSeparator"
       android:layout_width="match_parent"
       android:layout_height="30dp"
       android:visibility="gone"/>
   ...//some view down here
   

Now, I the code, all I needed to do it simple change the visibility to invisible (i.e. it's there, and taking the needed space, but it's unseen)

    JAVA:

    TextView tvSeparator = (TextView)activity.findViewById(R.id.dialogSeparator);
    tvSeparator.setVisibility(View.INVISIBLE);
    //Inside an activity extended class I can use 'this' instead of 'activity'.

Viola...I got the needed margin. BTW, This solution is for LinearLayout with vertical orientation, but you can do it with different layouts.

Hope this helps.

I would use "wkhtmltopdf". It just work great. It uses webkit engine (used in Chrome, Safari, etc.), and it is very easy to use:

wkhtmltopdf stackoverflow.com/questions/923885/ this_question.pdf

That's it!

Try it

I don't know what you consider pathological, but let me provide some alternatives you could have not seen before:

List<E> sl= list ;
while( ! sl.empty() ) {
    E element= sl.get(0) ;
    .....
    sl= sl.subList(1,sl.size());
}

Or its recursive version:

void visit(List<E> list) {
    if( list.isEmpty() ) return;
    E element= list.get(0) ;
    ....
    visit(list.subList(1,list.size()));
}

Also, a recursive version of the classical for(int i=0... :

void visit(List<E> list,int pos) {
    if( pos >= list.size() ) return;
    E element= list.get(pos) ;
    ....
    visit(list,pos+1);
}

I mention them because you are "somewhat new to Java" and this could be interesting.

Say your variable is myNode, you can do myNode.value to retrieve the value of input elements.

Firebug has a "DOM" tab which shows useful DOM attributes.

Looks like YouTube has updated their JS API so this is available by default! You can use an existing YouTube iframe's ID...

<iframe id="player" src="http://www.youtube.com/embed/M7lc1UVf-VE?enablejsapi=1&origin=http://example.com" frameborder="0"></iframe>

...in your JS...

var player;
function onYouTubeIframeAPIReady() {
  player = new YT.Player('player', {
    events: {
      'onStateChange': onPlayerStateChange
    }
  });
}

function onPlayerStateChange() {
  //...
}

...and the constructor will use your existing iframe instead of replacing it with a new one. This also means you don't have to specify the videoId to the constructor.

Is there a way to convert an Integer[] array to an int[] array?

This gross omission from the Java core libraries seems to come up on pretty much every project I ever work on. And as convenient as the Trove library might be, I am unable to parse the precise requirements to meet LPGL for an Android app that statically links an LGPL library (preamble says ok, body does not seem to say the same). And it's just plain inconvenient to go rip-and-stripping Apache sources to get these classes. There has to be a better way.

Use F string if you are using python v3.7

xstr = F"{s}"

The best "Pythonic" way to do this, exploiting the with statement, is listed as Example #6 in PEP 343, which gives the background of the statement.

@contextmanager
def opened_w_error(filename, mode="r"):
    try:
        f = open(filename, mode)
    except IOError, err:
        yield None, err
    else:
        try:
            yield f, None
        finally:
            f.close()

Used as follows:

with opened_w_error("/etc/passwd", "a") as (f, err):
    if err:
        print "IOError:", err
    else:
        f.write("guido::0:0::/:/bin/sh\n")

This is implementation dependent, as the C standard does NOT define the signed-ness of char. Depending on the platform, char may be signed or unsigned, so you need to explicitly ask for signed char or unsigned char if your implementation depends on it. Just use char if you intend to represent characters from strings, as this will match what your platform puts in the string.

The difference between signed char and unsigned char is as you'd expect. On most platforms, signed char will be an 8-bit two's complement number ranging from -128 to 127, and unsigned char will be an 8-bit unsigned integer (0 to 255). Note the standard does NOT require that char types have 8 bits, only that sizeof(char) return 1. You can get at the number of bits in a char with CHAR_BIT in limits.h. There are few if any platforms today where this will be something other than 8, though.

There is a nice summary of this issue here.

As others have mentioned since I posted this, you're better off using int8_t and uint8_t if you really want to represent small integers.

useStyles is a React hook which are meant to be used in functional components and can not be used in class components.

From React:

Hooks let you use state and other React features without writing a class.

Also you should call useStyles hook inside your function like;

function Welcome() {
  const classes = useStyles();
...

If you want to use hooks, here is your brief class component changed into functional component;

import React from "react";
import { Container, makeStyles } from "@material-ui/core";

const useStyles = makeStyles({
  root: {
    background: "linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)",
    border: 0,
    borderRadius: 3,
    boxShadow: "0 3px 5px 2px rgba(255, 105, 135, .3)",
    color: "white",
    height: 48,
    padding: "0 30px"
  }
});

function Welcome() {
  const classes = useStyles();
  return (
    <Container className={classes.root}>
      <h1>Welcome</h1>
    </Container>
  );
}

export default Welcome;

If you have more than one network adapter and more than one adapter is active (f.e WLAN + VPN) you need a bit more complex check. You can use this one-liner:

[System.Net.DNS]::GetHostByAddress(([System.Net.DNS]::GetHostAddresses([System.Environment]::MachineName) | Where-Object { $_.AddressFamily -eq "InterNetwork" } | Select-Object IPAddressToString)[0].IPAddressToString).HostName.ToLower()

The first answer doesn't reflect the current Container vs Presenter paradigm.

If you need to do something, like validate a password, you'd likely have a function that does it. You'd be passing that function to your reusable view as a prop.

Containers

So, the correct way to do it is to write a ValidatorContainer, which will have that function as a property, and wrap the form in it, passing the right props in to the child. When it comes to your view, your validator container wraps your view and the view consumes the containers logic.

Validation could be all done in the container's properties, but it you're using a 3rd party validator, or any simple validation service, you can use the service as a property of the container component and use it in the container's methods. I've done this for restful components and it works very well.

Providers

If there's a bit more configuration necessary, you can use a Provider/Consumer model. A provider is a high level component that wraps somewhere close to and underneath the top application object (the one you mount) and supplies a part of itself, or a property configured in the top layer, to the context API. I then set my container elements to consume the context.

The parent/child context relations don't have to be near each other, just the child has to be descended in some way. Redux stores and the React Router function in this way. I've used it to provide a root restful context for my rest containers (if I don't provide my own).

(note: the context API is marked experimental in the docs, but I don't think it is any more, considering what's using it).

//An example of a Provider component, takes a preconfigured restful.js_x000D_
//object and makes it available anywhere in the application_x000D_
export default class RestfulProvider extends React.Component {_x000D_
 constructor(props){_x000D_
  super(props);_x000D_
_x000D_
  if(!("restful" in props)){_x000D_

Middleware

A further way I haven't tried, but seen used, is to use middleware in conjunction with Redux. You define your service object outside the application, or at least, higher than the redux store. During store creation, you inject the service into the middleware and the middleware handles any actions that affect the service.

In this way, I could inject my restful.js object into the middleware and replace my container methods with independent actions. I'd still need a container component to provide the actions to the form view layer, but connect() and mapDispatchToProps have me covered there.

The new v4 react-router-redux uses this method to impact the state of the history, for example.

//Example middleware from react-router-redux_x000D_
//History is our service here and actions change it._x000D_
_x000D_
import { CALL_HISTORY_METHOD } from './actions'_x000D_
_x000D_
/**_x000D_
 * This middleware captures CALL_HISTORY_METHOD actions to redirect to the_x000D_
 * provided history object. This will prevent these actions from reaching your_x000D_
 * reducer or any middleware that comes after this one._x000D_
 */_x000D_
export default function routerMiddleware(history) {_x000D_
  return () => next => action => {_x000D_
    if (action.type !== CALL_HISTORY_METHOD) {_x000D_
      return next(action)_x000D_
    }_x000D_
_x000D_
    const { payload: { method, args } } = action_x000D_
    history[method](...args)_x000D_
  }_x000D_
}

In the command prompt, type the command below and press Enter.

bcdedit /enum

Under the Windows Boot Loader sections, make note of the identifier value.

To start in safe mode from command prompt :

bcdedit /set {identifier} safeboot minimal 

Then enter the command line to reboot your computer.

You have to add the following code in the manifest.xml file. The activity for which it should not rotate, in that activity add this element

android:screenOrientation="portrait"

Then it will not rotate.

uh? imo this is much simpler

  set /p texte=< file.txt  
  echo %texte%

Looks like the secret key isn't on the other machine, so even with the right passphrase (read from a file) it wouldn't work.

These options should work, to

• Either copy the keyrings (maybe only secret keyring required, but public ring is public anyway) over to the other machine
• Or export the secret key & then import it on the other machine

A few useful looking options from man gpg:

--export
Either export all keys from all keyrings (default keyrings and those registered via option --keyring), or if at least one name is given, those of the given name. The new keyring is written to STDOUT or to the file given with option --output. Use together with --armor to mail those keys.

--export-secret-keys
Same as --export, but exports the secret keys instead.

--import
--fast-import
Import/merge keys. This adds the given keys to the keyring. The fast version is currently just a synonym.

And maybe

--keyring file
Add file to the current list of keyrings. If file begins with a tilde and a slash, these are replaced by the $HOME directory. If the file- name does not contain a slash, it is assumed to be in the GnuPG home directory ("~/.gnupg" if --homedir or $GNUPGHOME is not used).

Note that this adds a keyring to the current list. If the intent is to use the specified keyring alone, use --keyring along with --no-default-keyring.

--secret-keyring file
Same as --keyring but for the secret keyrings.

you can use the identity

            log[a]x
 log[b]x = ---------
            log[a]b

so this would be applicable for log2.

            log[10]x
 log[2]x = ----------
            log[10]2

just plug this into the java Math log10 method....

You're calling write_file with arguments like this:

write_file(foo, bar)

But you haven't defined 'foo' correctly, or you have a typo in your code so that it's creating a new empty variable and passing it in.

Empty lists evaluate to False in boolean contexts (such as if some_list:).

Didn't wan to mess with carbon. So here's my solution

$start = new \DateTime('now');
$start->modify('first day of this month');
$end = new \DateTime('now');
$end->modify('last day of this month');

$new_releases = Game::whereBetween('release', array($start, $end))->get();

Look at this paper, "Learning the k in k-means" by Greg Hamerly, Charles Elkan. It uses a Gaussian test to determine the right number of clusters. Also, the authors claim that this method is better than BIC which is mentioned in the accepted answer.

The Html.TextboxFor always creates a textbox (<input type="text" ...).

While the EditorFor looks at the type and meta information, and can render another control or a template you supply.

For example for DateTime properties you can create a template that uses the jQuery DatePicker.

I think you misunderstood some core concepts about iOS modal view controllers. When you dismiss VC1, any presented view controllers by VC1 are dismissed as well. Apple intended for modal view controllers to flow in a stacked manner - in your case VC2 is presented by VC1. You are dismissing VC1 as soon as you present VC2 from VC1 so it is a total mess. To achieve what you want, buttonPressedFromVC1 should have the mainVC present VC2 immediately after VC1 dismisses itself. And I think this can be achieved without delegates. Something along the lines:

UIViewController presentingVC = [self presentingViewController];
[self dismissViewControllerAnimated:YES completion:
 ^{
    [presentingVC presentViewController:vc2 animated:YES completion:nil];
 }];

Note that self.presentingViewController is stored in some other variable, because after vc1 dismisses itself, you shouldn't make any references to it.

I got this working by hard setting the attribute. And controlling the attribute applicability using the boolean value for the attribute.

Here is the code snippet:

<div contenteditable="{{ condition ? 'true' : 'false'}}"></div>

I hope this helps.

The preferred approach should be:

Double.valueOf(d).longValue()

From the Double (Java Platform SE 7) documentation:

Double.valueOf(d)

Returns a Double instance representing the specified double value. If a new Double instance is not required, this method should generally be used in preference to the constructor Double(double), as this method is likely to yield significantly better space and time performance by caching frequently requested values.

Method 1:USE PDO query method

$stmt = $db->query('SELECT id FROM Employee where name ="'.$name.'"');
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

Getting Row Count

$stmt = $db->query('SELECT id FROM Employee where name ="'.$name.'"');
$row_count = $stmt->rowCount();
echo $row_count.' rows selected';

Method 2: Statements With Parameters

$stmt = $db->prepare("SELECT id FROM Employee WHERE name=?");
$stmt->execute(array($name));
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

Method 3:Bind parameters

$stmt = $db->prepare("SELECT id FROM Employee WHERE name=?");
$stmt->bindValue(1, $name, PDO::PARAM_STR);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

**bind with named parameters**
$stmt = $db->prepare("SELECT id FROM Employee WHERE name=:name");
$stmt->bindValue(':name', $name, PDO::PARAM_STR);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

or
$stmt = $db->prepare("SELECT id FROM Employee WHERE name=:name");
$stmt->execute(array(':name' => $name));
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

Want to know more look at this link

Iterator<JSONObject> iterator = jsonObject.values().iterator();

while (iterator.hasNext()) {
 jsonChildObject = iterator.next();

 // Do whatever you want with jsonChildObject 

  String id = (String) jsonChildObject.get("id");
}

In the google io session about NFC, qa section. There was such a question:

card emulation? No API support for card emulation No consistent user experience when doing card emulation and no compelling story

I resolve this problem on NodeJS like this:

var util = require('util');

// Our circular object
var obj = {foo: {bar: null}, a:{a:{a:{a:{a:{a:{a:{hi: 'Yo!'}}}}}}}};
obj.foo.bar = obj;

// Generate almost valid JS object definition code (typeof string)
var str = util.inspect(b, {depth: null});

// Fix code to the valid state (in this example it is not required, but my object was huge and complex, and I needed this for my case)
str = str
    .replace(/<Buffer[ \w\.]+>/ig, '"buffer"')
    .replace(/\[Function]/ig, 'function(){}')
    .replace(/\[Circular]/ig, '"Circular"')
    .replace(/\{ \[Function: ([\w]+)]/ig, '{ $1: function $1 () {},')
    .replace(/\[Function: ([\w]+)]/ig, 'function $1(){}')
    .replace(/(\w+): ([\w :]+GMT\+[\w \(\)]+),/ig, '$1: new Date("$2"),')
    .replace(/(\S+): ,/ig, '$1: null,');

// Create function to eval stringifyed code
var foo = new Function('return ' + str + ';');

// And have fun
console.log(JSON.stringify(foo(), null, 4));

Another solution is to use "offsetTop", like this:

var elementPosition = document.getElementById('id').offsetTop;

window.scrollTo({
  top: elementPosition - 10, //add your necessary value
  behavior: "smooth"  //Smooth transition to roll
});

 //How to start another application from the current application
 Process runProg = new Process();
 runProg.StartInfo.FileName = pathToFile; //the path of the application
 runProg.StartInfo.Arguments = genArgs; //any arguments you want to pass
 runProg.StartInfo.CreateNoWindow = true;
 runProg.Start();

 //How to end the same application from the current application
 int IDstring = System.Convert.ToInt32(runProg.Id.ToString());
 Process tempProc = Process.GetProcessById(IDstring);
 tempProc.CloseMainWindow();
 tempProc.WaitForExit();

You're trying to create a tuple, but you're just parenthesizing a string :)

Add an extra ',':

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,))  # <- note extra ','
processThread.start()

Or use brackets to make a list:

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved])  # <- 1 element list
processThread.start()

If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)

The *self.__args turns your string into a list of characters, passing them to the processLine function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.

You can also use TempVars - note '!' syntax is essential

It's not the most efficient solution but the most terse code would be:

boolean equalLists = listA.size() == listB.size() && listA.containsAll(listB);

Update:

@WesleyPorter is right. The solution above will not work if duplicate objects are in the collection.
For a complete solution you need to iterate over a collection so duplicate objects are handled correctly.

private static boolean cmp( List<?> l1, List<?> l2 ) {
    // make a copy of the list so the original list is not changed, and remove() is supported
    ArrayList<?> cp = new ArrayList<>( l1 );
    for ( Object o : l2 ) {
        if ( !cp.remove( o ) ) {
            return false;
        }
    }
    return cp.isEmpty();
}

Update 28-Oct-2014:

@RoeeGavriel is right. The return statement needs to be conditional. The code above is updated.

public static Date convertTimestampToDate(Timestamp timestamp)  {
        Instant ins=timestamp.toLocalDateTime().atZone(ZoneId.systemDefault()).toInstant();
        return  Date.from(ins);
}

I think you may be able to do this with the metaclass. Since the metaclass can be like a class for the class (if that makes sense). I know you can assign a __call__() method to the metaclass to override calling the class, MyClass(). I wonder if using the property decorator on the metaclass operates similarly. (I haven't tried this before, but now I'm curious...)

[update:]

Wow, it does work:

class MetaClass(type):    
    def getfoo(self):
        return self._foo
    foo = property(getfoo)

    @property
    def bar(self):
        return self._bar

class MyClass(object):
    __metaclass__ = MetaClass
    _foo = 'abc'
    _bar = 'def'

print MyClass.foo
print MyClass.bar

Note: This is in Python 2.7. Python 3+ uses a different technique to declare a metaclass. Use: class MyClass(metaclass=MetaClass):, remove __metaclass__, and the rest is the same.

I think you can use MDC to change logging level programmatically. The code below is an example to change logging level on current thread. This approach does not create dependency to logback implementation (SLF4J API contains MDC).

<configuration>
  <turboFilter class="ch.qos.logback.classic.turbo.DynamicThresholdFilter">
    <Key>LOG_LEVEL</Key>
    <DefaultThreshold>DEBUG</DefaultThreshold>
    <MDCValueLevelPair>
      <value>TRACE</value>
      <level>TRACE</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>DEBUG</value>
      <level>DEBUG</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>INFO</value>
      <level>INFO</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>WARN</value>
      <level>WARN</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>ERROR</value>
      <level>ERROR</level>
    </MDCValueLevelPair>
  </turboFilter>
  ......
</configuration>

MDC.put("LOG_LEVEL", "INFO");

just add them like this :

        String character = "a";
        String otherString = "helen";
        otherString=otherString+character;
        System.out.println(otherString);

Just recently experienced this:

System.ServiceModel.CommunicationException:

An error occurred while making the HTTP request to http://example.com/WebServices/SomeService.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send.

---> System.IO.IOException: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.

I found out from an administrator that the IIS application pool that was hosting the web service recycled automatically after running out of memory. The error on the client occurred when the application pool recycled.

Increasing the memory available to the application pool resolved the immediate issue.

To print the content of Root store:

certutil -store Root

To output content to a file:

certutil -store Root > root_content.txt

To add certificate to Root store:

certutil -addstore -enterprise Root file.cer

Love VonC's answer. Here's an easy version of it for beginners.

There is a git remote called origin which I am sure you are all aware of. Basically, you can add as many remotes to a git repo as you want. So, what we can do is introduce a new remote which is the original repo not the fork. I like to call it original

Let's add original repo's to our fork as a remote.

git remote add original https://git-repo/original/original.git

Now let's fetch the original repo to make sure we have the latest coded

git fetch original

As, VonC suggested, make sure we are on the master.

git checkout master

Now to bring our fork up to speed with the latest code on original repo, all we have to do is hard reset our master branch in accordance with the original remote.

git reset --hard original/master

And you are done :)

androidx will replace support library after 28.0.0. You should migrate your project to use it. androidx uses Semantic Versioning. Using AndroidX will not be confused by version that is presented in library name and package name. Life becomes easier

add {3,5} to your expression which means length between 3 to 5

/^([a-zA-Z0-9_-]){3,5}$/

You can just pass the column names as a list with specifying the axis as 0 or 1

• axis=1: Along the Rows
• axis=0: Along the Columns

• By default axis=0

  data.drop(["Colname1","Colname2","Colname3","Colname4"],axis=1)

..extending Mikaels' answers

SELECT
  CASE WHEN ISNUMERIC(QTY + 'e0') = 1 THEN CAST(QTY AS float) ELSE null END AS MyFloat
  CASE WHEN ISNUMERIC(QTY + 'e0') = 0 THEN QTY ELSE null END AS MyVarchar
FROM
  ...

• Two data types requires two columns
• Adding e0 fixes some ISNUMERIC issues (such as + - . and empty string being accepted)

A different approach is to refactor the code from two for loops into a for loop and one manual loop. That way the break in the manual loop applies to the outer loop. I used this once in a Gauss-Jordan Elimination which required three nested loops to process.

for (int i = 0; i < 1000; i++)
{
    int j = 0;

MANUAL_LOOP:;

    if (j < 1000)
    {
       if (condition)
       {
           break;
       }

       j++;
       goto MANUAL_LOOP;
    }
}

This query uses DMV's to identify the most costly queries by CPU

        qs.total_worker_time/1000000,
    average_CPU_inSeconds = --Converted from microseconds
        (qs.total_worker_time/1000000) / qs.execution_count,
    qs.total_elapsed_time,
    total_elapsed_time_inSeconds = --Converted from microseconds

Simplest solution seems to be specifying the ylim range. Here is some code to do this automatically (left default, right - adjusted):

# default y-axis
barplot(dat, beside=TRUE)

# automatically adjusted y-axis
barplot(dat, beside=TRUE, ylim=range(pretty(c(0, dat))))

The trick is to use pretty() which returns a list of interval breaks covering all values of the provided data. It guarantees that the maximum returned value is 1) a round number 2) greater than maximum value in the data.

In the example 0 was also added pretty(c(0, dat)) which makes sure that axis starts from 0.

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.

Using a single for loop:

var table = document.getElementById('tableID');  
var count = table.rows.length;  
for(var i=0; i<count; i++) {    
    console.log(table.rows[i]);    
}

Mostly, I prefer to use this syntax :

if ($('#MyId')!= null) {
    // dostuff
}

Even if this code is not commented, the functionality is obvious.

<div>
    <iframe id="myFrame" src="https://player.vimeo.com/video/12345678?autoplay=1" width="640" height="360" frameborder="0" allowfullscreen> . 
    </iframe>
</div>

<script>
    function myFunction() {
        var wscreen = window.innerWidth;
        var hscreen = window.innerHeight;

        document.getElementById("myFrame").width = wscreen ;
        document.getElementById("myFrame").height = hscreen ;
    }

    myFunction();

    window.addEventListener('resize', function(){ myFunction(); });
</script>

this works on Vimeo adding an id myFrame to the iframe

Double click on it and you're good to go.

You might be interested in the SciPy Stats package. It has the percentile function you're after and many other statistical goodies.

percentile() is available in numpy too.

import numpy as np
a = np.array([1,2,3,4,5])
p = np.percentile(a, 50) # return 50th percentile, e.g median.
print p
3.0

This ticket leads me to believe they won't be integrating percentile() into numpy anytime soon.

You can use the following for an awk solution -

awk '/^#/ {sub(/#.*/,"");getline;}1' inputfile

No. You have to make your own like this:

boolean tryParseInt(String value) {  
     try {  
         Integer.parseInt(value);  
         return true;  
      } catch (NumberFormatException e) {  
         return false;  
      }  
}

...and you can use it like this:

if (tryParseInt(input)) {  
   Integer.parseInt(input);  // We now know that it's safe to parse
}

EDIT (Based on the comment by @Erk)

Something like follows should be better

public int tryParse(String value, int defaultVal) {
    try {
        return Integer.parseInt(value);
    } catch (NumberFormatException e) {
        return defaultVal;
    }
}

When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.

public int tryParse(String value) {
    return tryParse(value, 0)
}

There are instructions on how to install sshpass here:

https://gist.github.com/arunoda/7790979

For Mac you will need to install xcode and command line tools then use the unofficial Homewbrew command:

brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

To add MP3 reading support to Java Sound, add the mp3plugin.jar of the JMF to the run-time class path of the application.

Note that the Clip class has memory limitations that make it unsuitable for more than a few seconds of high quality sound.

What worked for me was:

<div style='display: inline-flex; width: 80px; height: 80px;'>
<img style='max-width: 100%; max-height: 100%' src='image file'>
</div>

inline-flex was required to keep the images from going outside of the div.

$sqlquery = "SELECT field1, field2 FROM table WHERE columnA <> 'x' AND columbB <> 'y'";

I'd suggest using the diamond operator (<>) in favor of != as the first one is valid SQL and the second one is a MySQL addition.

ggplot2 and scales packages can do that:

y <- c(12, 20)/100
x <- c(1, 2)

library(ggplot2)
library(scales)
myplot <- qplot(as.factor(x), y, geom="bar")
myplot + scale_y_continuous(labels=percent)

It seems like the stat() option has been taken off, causing the error message. Try this:

library(scales)

myplot <- ggplot(mtcars, aes(factor(cyl))) + 
          geom_bar(aes(y = (..count..)/sum(..count..))) + 
          scale_y_continuous(labels=percent)

Specifically regarding "Can I rely completely upon jquery html() method that it'll perform like innerHTML" my answer is NO!

Run this in internet explorer 7 or 8 and you'll see.

jQuery produces bad HTML when setting HTML containing a <FORM> tag nested within a <P> tag where the beginning of the string is a newline!

There are several test cases here and the comments when run should be self explanatory enough. This is quite obscure, but not understanding what's going on is a little disconcerting. I'm going to file a bug report.

I found a interesting library on npm that might be of some use to you. It's called mime(npm install mime or https://github.com/broofa/node-mime) and it can determine the mime type of a file. Here's an example of a webserver I wrote using it:

var mime = require("mime"),http = require("http"),fs = require("fs");
http.createServer(function (req, resp) {
path  = unescape(__dirname + req.url)
var code = 200
 if(fs.existsSync(path)) {
    if(fs.lstatSync(path).isDirectory()) {
        if(fs.existsSync(path+"index.html")) {
        path += "index.html"
        } else {
            code = 403
            resp.writeHead(code, {"Content-Type": "text/plain"});
            resp.end(code+" "+http.STATUS_CODES[code]+" "+req.url);
        }
    }
    resp.writeHead(code, {"Content-Type": mime.lookup(path)})
    fs.readFile(path, function (e, r) {
    resp.end(r);

})
} else {
    code = 404
    resp.writeHead(code, {"Content-Type":"text/plain"});
    resp.end(code+" "+http.STATUS_CODES[code]+" "+req.url);
}
console.log("GET "+code+" "+http.STATUS_CODES[code]+" "+req.url)
}).listen(9000,"localhost");
console.log("Listening at http://localhost:9000")

This will serve any regular text or image file (.html, .css, .js, .pdf, .jpg, .png, .m4a and .mp3 are the extensions I've tested, but it theory it should work for everything)

Developer Notes

Here is an example of output that I got with it:

Notice the unescape function in the path construction. This is to allow for filenames with spaces and encoded characters.

I assume that you're running a Linux, and you're using gEdit to edit your files. In the /etc/nginx/sites-enabled, it may have left a temp file e.g. default~ (watch the ~).

Depending on your editor, the file could be named .save or something like it. Just run $ ls -lah to see which files are unintended to be there and remove them (Thanks @Tisch for this).

Delete this file, and it will solve your problem.

Executing PHP functions by the onclick event is a cumbersome task and near impossible.

Instead you can redirect to another PHP page.

Say you are currently on a page one.php and you want to fetch some data from this php script process the data and show it in another page i.e. two.php you can do it by writing the following code <button onclick="window.location.href='two.php'">Click me</button>

You don't need error handling in order to accomplish this. All you have to do is iterate over all of the Worksheets and check if the specified name exists:

For i = 1 To Worksheets.Count
    If Worksheets(i).Name = "MySheet" Then
        exists = True
    End If
Next i

If Not exists Then
    Worksheets.Add.Name = "MySheet"
End If

This is mainly due to the connection not been closed in the application. Use "MinPoolSize" and "MaxPoolSize" in the connection string.

if you use mdb use this code

    var visible_modal = $('.modal.show').attr('id'); // modalID or undefined
    if (visible_modal) { // modal is active
        $('#' + visible_modal).modal('hide'); // close modal
    }

Query for the last weeks:

SELECT *
FROM dual
WHERE search_date BETWEEN SUBDATE(CURDATE(), 7) AND CURDATE()

Try this

hasName = name ? 'Y' : 'N';

You can use the * operator before an iterable to expand it within the function call. For example:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

From the python documentation:

If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the ** operator.

TL;DR

Correct way to do this in mongo

Do not Use RegExp

Go natural And use mongodb's inbuilt indexing , search

Step 1 :

db.articles.insert(
   [
     { _id: 1, subject: "coffee", author: "xyz", views: 50 },
     { _id: 2, subject: "Coffee Shopping", author: "efg", views: 5 },
     { _id: 3, subject: "Baking a cake", author: "abc", views: 90  },
     { _id: 4, subject: "baking", author: "xyz", views: 100 },
     { _id: 5, subject: "Café Con Leche", author: "abc", views: 200 },
     { _id: 6, subject: "???????", author: "jkl", views: 80 },
     { _id: 7, subject: "coffee and cream", author: "efg", views: 10 },
     { _id: 8, subject: "Cafe con Leche", author: "xyz", views: 10 }
   ]
)
 

Step 2 :

Need to create index on whichever TEXT field you want to search , without indexing query will be extremely slow

db.articles.createIndex( { subject: "text" } )

step 3 :

db.articles.find( { $text: { $search: "coffee",$caseSensitive :true } } )  //FOR SENSITIVITY
db.articles.find( { $text: { $search: "coffee",$caseSensitive :false } } ) //FOR INSENSITIVITY


 

If you're meaning to make a server call from the client, you should use Ajax - look at something like Jquery and use $.Ajax() or $.getJson() to call the server function, depending on what kind of return you're after or action you want to execute.

This does the trick, without the need to add an inline style

<div class="row-fluid">
    <div class="span6">
        <p>text left</p>
    </div>
    <div class="span6">
        <div class="pull-right">
            <p>text right</p>
        </div>
    </div>
</div>

The answer is in nesting another <div> with the "pull-right" class. Combining the two classes won't work.

>>> "    xyz     ".rstrip()
'    xyz'

There is more about rstrip in the documentation.

You shouldn't change the stack. Android back button should work as in a web browser.

I can think of a way to do it, but it's quite a hack.

• Make your Activities singleTask by adding it to the AndroidManifest Example:

  <activity android:name=".activities.A"
            android:label="@string/A_title"
            android:launchMode="singleTask"/>
  
  <activity android:name=".activities.B"
            android:label="@string/B_title"
            android:launchMode="singleTask"/>
  

• Extend Application which will hold the logic of where to go.

Example:

public class DontHackAndroidLikeThis extends Application {

  private Stack<Activity> classes = new Stack<Activity>();

  public Activity getBackActivity() {
    return classes.pop();
  }

  public void addBackActivity(Activity activity) {
    classes.push(activity);
  }
}

From A to B:

DontHackAndroidLikeThis app = (DontHackAndroidLikeThis) getApplication();
app.addBackActivity(A.class); 
startActivity(this, B.class);

From B to C:

DontHackAndroidLikeThis app = (DontHackAndroidLikeThis) getApplication();
app.addBackActivity(B.class); 
startActivity(this, C.class);

In C:

If ( shouldNotGoBackToB() ) {
  DontHackAndroidLikeThis app = (DontHackAndroidLikeThis) getApplication();
  app.pop();
}

and handle the back button to pop() from the stack.

Once again, you shouldn't do this :)

To add on to others' answers, if you don't have access to that private key anymore it's fairly simple to get back up and running:

1. revoke your active certificate in the provisioning portal
2. create new developer certificate (keychain access/.../request for csr...etc.)
3. download and install a new certificate
4. create a new provisioning profile for existing app id (on provisioning portal)
5. download and install new provisioning profile and in the build, settings set the appropriate code signing identities

It worked for me with low_memory = False while importing a DataFrame. That is all the change that worked for me:

df = pd.read_csv('export4_16.csv',low_memory=False)

Maybe this code helps:

var chunk_size = 10;_x000D_
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];_x000D_
var groups = arr.map( function(e,i){ _x000D_
     return i%chunk_size===0 ? arr.slice(i,i+chunk_size) : null; _x000D_
}).filter(function(e){ return e; });_x000D_
console.log({arr, groups})

You could do this, which facilitates reading:

>&2 echo "error"

>&2 copies file descriptor #2 to file descriptor #1. Therefore, after this redirection is performed, both file descriptors will refer to the same file: the one file descriptor #2 was originally referring to. For more information see the Bash Hackers Illustrated Redirection Tutorial.

QUICK SOLUTION EVERY STEP:

Fixed error in VMware Workstation on Windows 10 host Transport (VMDB) error -14: Pipe connection has been broken.

Today we will be fixing VMWare error on a windows 10 computer.

1. In RUN box type "gpedit" then Goto [ERROR SEE POINT 3]

1- Computer Configuration

2- Administrative Templates

3- System - Device Guard : IF NO DEVICE GUARD : (DOWNLOAD https://www.microsoft.com/en-us/download/100591 install this "c:\Program Files (x86)\Microsoft Group Policy\Windows 10 November 2019 Update (1909)\PolicyDefinitions" COPY to c:\windows\PolicyDefinitions )

4- Turn on Virtualization Based Security. Now Double click that and "Disable"

2. Open Command Prompt as Administrator and type the following gpupdate /force [DONT DO IF YOU DONT HAVE DEVICE GUARD ELSE IT WILL GO AGAIN]

3. Open Registry Editor, now Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceGuard. Add a new DWORD value named EnableVirtualizationBasedSecurity and set it to 0 to disable it. Next Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA. Add a new DWORD value named LsaCfgFlags and set it to 0 to disable it.

4. In RUN box, type Turn Windows features on or off, now uncheck Hyper-V and restart system.

5. Open command prompt as a administrator and type the following commands

    bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader

    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"

    bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
    
    bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS

    bcdedit /set hypervisorlaunchtype off

Now, Restart your system

PHPmyadmin also accepts compressed files in gzip format, so you can gzip the file (Use 7Zip if you don't have any) and upload the zipped file. Since its a text file, it will have a good compress ratio.

Probably the most elegant way of doing this is to do it in one step. See val().

$("#text").val(function(i, val) {
  return val.replace('.', ':');
});

compared to:

var val = $("#text").val();
$("#text").val(val.replace('.', ':'));

From the docs:

.val( function(index, value) )

function(index, value)A function returning the value to set.

This method is typically used to set the values of form fields. For <select multiple="multiple"> elements, multiple s can be selected by passing in an array.

The .val() method allows us to set the value by passing in a function. As of jQuery 1.4, the function is passed two arguments, the current element's index and its current value:

$('input:text.items').val(function(index, value) {
  return value + ' ' + this.className;
});

This example appends the string " items" to the text inputs' values.

This requires jQuery 1.4+.

For those using CodeIgniter, there's a built-in Date Helper function called timezone_menu. These:

$this->load->helper('date');
echo timezone_menu('GMT', 'form-control', 'dropdown-name', ['id' => 'ci-timezone']);

Produce the following output:

I use a function to echo and run the command:

#!/bin/bash
# Function to display commands
exe() { echo "\$ $@" ; "$@" ; }

exe echo hello world

Which outputs

$ echo hello world
hello world

For more complicated commands pipes, etc., you can use eval:

#!/bin/bash
# Function to display commands
exe() { echo "\$ ${@/eval/}" ; "$@" ; }

exe eval "echo 'Hello, World!' | cut -d ' ' -f1"

Which outputs

$  echo 'Hello, World!' | cut -d ' ' -f1
Hello

Try using another temporary pair:

pair<string,double> temp;
vector<pair<string,double>> revenue;

// Inside the loop
temp.first = "string";
temp.second = map[i].second;
revenue.push_back(temp);

Riffing on the snippet provided as an alternative to hurry.filesize(), here is a snippet that gives varying precision numbers based on the prefix used. It isn't as terse as some snippets, but I like the results.

    """
    if size_bytes == 1:
        # because I really hate unnecessary plurals
        return "1 byte"

I think to be consistant it's nicer to use @throw with your own class that extends NSException. Then you use the same notations for try catch finally:

@try {
.....
}
@catch{
...
}
@finally{
...
}

Apple explains here how to throw and handle exceptions: Catching Exceptions Throwing Exceptions

As TASKKILL might be unavailable on some Home/basic editions of windows here some alternatives:

TSKILL processName

or

TSKILL PID

Have on mind that processName should not have the .exe suffix and is limited to 18 characters.

Another option is WMIC :

wmic Path win32_process Where "Caption Like 'MyProcess.exe'" Call Terminate

wmic offer even more flexibility than taskkill .With wmic Path win32_process get you can see the available fileds you can filter.

If you have a table with an IDENTITY column that you want to reset the next value for you can use the following command:

ALTER TABLE <table name> 
    ALTER COLUMN <column name> 
        RESTART WITH <new value to restart with>;

Here's a solution for those that may still be struggling. You want to add a mouseover event on the 'parent' element of the child element(s) you want detected. The below code shows you how to go about it.

const wrapper = document.getElementById('wrapper') //parent element
const position = document.getElementById("displaySelection")

wrapper.addEventListener('mousemove', function(e) {
  let elementPointed = document.elementFromPoint(e.clientX, e.clientY)

  console.log(elementPointed)
});

In C you can use memcpy. In C++ use std::copy from the <algorithm> header.

• For all object changes that need reactivity use Vue.set(object, prop, value)
• For array mutations, you can look at the currently supported list here

EDIT 1

For vuex you will want to do Vue.set(state.object, key, value)

So just for others who come to this question. It appears at some point in Vue 2.* they removed this.items.$set(index, val) in favor of this.$set(this.items, index, val).

Splice is still available and here is a link to array mutation methods available in vue link.

Sign-off is a line at the end of the commit message which certifies who is the author of the commit. Its main purpose is to improve tracking of who did what, especially with patches.

Example commit:

Add tests for the payment processor.

Signed-off-by: Humpty Dumpty <[email protected]>

It should contain the user real name if used for an open-source project.

If branch maintainer need to slightly modify patches in order to merge them, he could ask the submitter to rediff, but it would be counter-productive. He can adjust the code and put his sign-off at the end so the original author still gets credit for the patch.

Try this:

<div class="rmz-srchbg">
    <input type="text" id="globalsearchstr" name="search" value="" class="rmz-txtbox">
    <input type="submit" value="&nbsp;" id="srchbtn" class="rmz-srchico">
    <br style="clear:both;">
</div>
<script>
$(function(){
   $('#globalsearchstr').on('focus mouseenter', function(){
    $(this).parent().css("background", "url(/images/r-srchbg_white.png) no-repeat");
   });
});
</script>

var thisList = new List<string>{ "a", "b", "c" };
var otherList = new List<string> {"a", "b"};

var theOnesThatDontMatch = thisList
        .Where(item=> otherList.All(otherItem=> item != otherItem))
        .ToList();

var theOnesThatDoMatch = thisList
        .Where(item=> otherList.Any(otherItem=> item == otherItem))
        .ToList();

Console.WriteLine("don't match: {0}", string.Join(",", theOnesThatDontMatch));
Console.WriteLine("do match: {0}", string.Join(",", theOnesThatDoMatch));

//Output:
//don't match: c
//do match: a,b

Adapt the list types and lambdas accordingly, and you can filter out anything.

Well, PHP can do this easily.

It can be done with the PHP mail() function. Here's what a simple function would look like:

<?php     
$to_email = '[email protected]';
$subject = 'Testing PHP Mail';
$message = 'This mail is sent using the PHP mail function';
$headers = 'From: [email protected]';
mail($to_email,$subject,$message,$headers);
?>

This will send a background e-mail to the recipient specified in the $to_email.

The above example uses hard coded values in the source code for the email address and other details for simplicity.

Let’s assume you have to create a contact us form for users fill in the details and then submit.

1. Users can accidently or intentional inject code in the headers which can result in sending spam mail
2. To protect your system from such attacks, you can create a custom function that sanitizes and validates the values before the mail is sent.

Let’s create a custom function that validates and sanitizes the email address using the filter_var() built in function.

Here's an example code:

<?php 
function sanitize_my_email($field) {
    $field = filter_var($field, FILTER_SANITIZE_EMAIL);
    if (filter_var($field, FILTER_VALIDATE_EMAIL)) {
        return true;
    } else {
        return false;
    }
}
$to_email = '[email protected]';
$subject = 'Testing PHP Mail';
$message = 'This mail is sent using the PHP mail ';
$headers = 'From: [email protected]';
//check if the email address is invalid $secure_check
$secure_check = sanitize_my_email($to_email);
if ($secure_check == false) {
    echo "Invalid input";
} else { //send email 
    mail($to_email, $subject, $message, $headers);
    echo "This email is sent using PHP Mail";
}
?>

We will now let this be a separate PHP file, for example sendmail.php.

Then, will use this file on form submission, using the action attribute of the form, like:

<form action="sendmail.php" method="post">
   <input type="text" value="Your Name: ">
   <input type="password" value="Set Up A Passworrd">
   <input type="submit" value="Signup">
   <input type="reset" value="Reset Form">
</form>

Hope I could help

Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

You can set the hours, minutes, seconds and microseconds to whatever you like

datetime.datetime.today().replace(hour=0, minute=0, second=0, microsecond=0)

but trutheality's answer is probably best when they are all to be zero and you can just compare the .date()s of the times

Maybe it is faster though if you have to compare hundreds of datetimes because you only need to do the replace() once vs hundreds of calls to date()

SELECT COUNT(1) FROM MyTable WHERE ...

will loop thru all the records. This is the reason it is bad to use for record existence.

I would use

SELECT TOP 1 * FROM MyTable WHERE ...

After finding 1 record, it will terminate the loop.

Try docker logout first, then relogin with docker login

Your worker method needs 'self' as a parameter, since it is a class method and not a function. Adding that should make it work fine.

I can't say it's an appropriate solution but you can try this.

Steps

• I am hoping that you have already cloned your repo.
• Now copy the file somewhere outside of your project.
• Add that filename with a location in gitigonre file.
• Remove that file from your local project.
• Push your code to remote origin.
• And now add that copied file into your project it'll be ignored.

This is just a hack solution if you want to maintain the history and don't to create mass in it.

If you don't want to use this solution please kindly ignore and try to avoid devote it. Because I am really trying to increase my score on this side

Found this post on a Google search, and it solved my issue thanks to @jwal reply, but I made one addition to his solution.

img.content.x700 {
  width: auto !important; /*override the width below*/
  width: 100%;
  max-width: 678px;
  float: left;
  clear: both;
}

With the above I changed the max-width to the dimensions of the content container that my image is in. In this case it is: container width - padding - boarder = max width

This way my image won't break out of the containing div, and I can still float the image within the content div.

I've tested in IE 9, FireFox 18.0.2 and Chrome 25.0.1364.97, Safari iOS and seems to work.

Additional: I tested this on an image 1024px wide displayed at 678px (the max width), and an image 500px wide displayed at 500px (width of the image).
