//global savedrange variable to store text range in
var savedrange = null;

function getSelection()
{
    var savedRange;
    if(window.getSelection && window.getSelection().rangeCount > 0) //FF,Chrome,Opera,Safari,IE9+
    {
        savedRange = window.getSelection().getRangeAt(0).cloneRange();
    }
    else if(document.selection)//IE 8 and lower
    { 
        savedRange = document.selection.createRange();
    }
    return savedRange;
}

$('#contentbox').keyup(function() { 
    var currentRange = getSelection();
    if(window.getSelection)
    {
        //do stuff with standards based object
    }
    else if(document.selection)
    { 
        //do stuff with microsoft object (ie8 and lower)
    }
});

Note: the range object its self can be stored in a variable, and can be re-selected at any time unless the contents of the contenteditable div change.

Reference for IE 8 and lower: http://msdn.microsoft.com/en-us/library/ms535872(VS.85).aspx

Reference for standards (all other) browsers: https://developer.mozilla.org/en/DOM/range (its the mozilla docs, but code works in chrome, safari, opera and ie9 too)

I had a related situation, where I specifically needed to set the cursor position to the END of a contenteditable div. I didn't want to use a full fledged library like Rangy, and many solutions were far too heavyweight.

In the end, I came up with this simple jQuery function to set the carat position to the end of a contenteditable div:

$.fn.focusEnd = function() {
    $(this).focus();
    var tmp = $('<span />').appendTo($(this)),
        node = tmp.get(0),
        range = null,
        sel = null;

    if (document.selection) {
        range = document.body.createTextRange();
        range.moveToElementText(node);
        range.select();
    } else if (window.getSelection) {
        range = document.createRange();
        range.selectNode(node);
        sel = window.getSelection();
        sel.removeAllRanges();
        sel.addRange(range);
    }
    tmp.remove();
    return this;
}

The theory is simple: append a span to the end of the editable, select it, and then remove the span - leaving us with a cursor at the end of the div. You could adapt this solution to insert the span wherever you want, thus putting the cursor at a specific spot.

Usage is simple:

$('#editable').focusEnd();

That's it!

In most browsers, you need the Range and Selection objects. You specify each of the selection boundaries as a node and an offset within that node. For example, to set the caret to the fifth character of the second line of text, you'd do the following:

function setCaret() {
    var el = document.getElementById("editable")
    var range = document.createRange()
    var sel = window.getSelection()
    
    range.setStart(el.childNodes[2], 5)
    range.collapse(true)
    
    sel.removeAllRanges()
    sel.addRange(range)
}

<div id="editable" contenteditable="true">
  text text text<br>text text text<br>text text text<br>
</div>

<button id="button" onclick="setCaret()">focus</button>

IE < 9 works completely differently. If you need to support these browsers, you'll need different code.

jsFiddle example: http://jsfiddle.net/timdown/vXnCM/

Try like below... it will help you...

Some time in Window Form Focus() doesn't work correctly. So better you can use Select() to focus the textbox.

txtbox.Select(); // to Set Focus
txtbox.Select(txtbox.Text.Length, 0); //to set cursor at the end of textbox

A warning about the Jquery Caret plugin.

It will conflict with the Masked Input plugin (or vice versa). Fortunately the Masked Input plugin includes a caret() function of its own, which you can use very similarly to the Caret plugin for your basic needs - $(element).caret().begin or .end

I wrote a plugin which enables me to navigate the file without moving the cursor position. It's based on folding the lines between your position and your target position and then jumping over the fold, or abort it and don't move at all.

It's also easy to fast-switch between the cursor on the first line, the last line and cursor in the middle by just clicking j, k or l when you are in the mode of the plugin.

I guess it would be a good fit here.

All the other answers are just focus on the IDE level, these are not the most effective and elegant way to generate getters and setters. If you have tens of attributes, the relevant getters and setters methods will make your class code very verbose.

The best way I ever used to generate getters and setters automatically is using project lombok annotations in your java project, lombok.jar will generate getter and setter method when you compile java code.

You just focus on class attributes/variables naming and definition, lombok will do the rest. This is easy to maintain your code.

For example, if you want to add getter and setter method for age variable, you just add two lombok annotations:

@Getter @Setter 
public int age = 10;

This is equal to code like that:

private int age = 10;
public int getAge() {
    return age;
}
public void setAge(int age) {
    this.age = age;
}

You can find more details about lombok here: Project Lombok

You can add as many classes to an element, but you can add only one id per element.

<div id="unique" class="class1 class2 class3 class4"></div>

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

I would vote for ServiceStack's JSON Serializer:

using ServiceStack;

string jsonString = new { FirstName = "James" }.ToJson();

It is also the fastest JSON serializer available for .NET: http://www.servicestack.net/benchmarks/

Use FileSaver.js. It supports Chrome, Edge, Firefox, and IE 10+ (and probably IE < 10 with a few "polyfills" - see Note 4). FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it:
     https://github.com/eligrey/FileSaver.js

Minified version is really small at < 2.5KB, gzipped < 1.2KB.

Usage:

/* TODO: replace the blob content with your byte[] */
var blob = new Blob([yourBinaryDataAsAnArrayOrAsAString], {type: "application/octet-stream"});
var fileName = "myFileName.myExtension";
saveAs(blob, fileName);

You might need Blob.js in some browsers (see Note 3). Blob.js implements the W3C Blob interface in browsers that do not natively support it. It is a cross-browser implementation:
     https://github.com/eligrey/Blob.js

Consider StreamSaver.js if you have files larger than blob's size limitations.

If you look at the down arrow in environment tab. The attached file can appear multiple times. You may need to highlight and run detach(filename) several times until all cases are gone then attach(newfilename) should have no output message.

More generally, you can also convert the new data into an array and use something like concat:

var newData = this.state.data.concat([data]);  
this.setState({data: newData})

Inside container(in docker, not in VM), by default these are not installed. Even apt-get, wget will not work. My VM is running on Ubuntu 17.10. For me yum package manaager worked.

Yum is not part of debian or ubuntu. It is part of red-hat. But, it works in Ubuntu and it is installed by default like apt-get

Tu install vim, use this command

yum install -y vim-enhanced 

To uninstall vim :

yum uninstall -y vim-enhanced 

Similarly,

yum install -y wget 
yum install -y sudo 

-y is for assuming yes if prompted for any qustion asked after doing yum install packagename

Bootstrap 4 has many different ways to align navbar items. float-right won't work because the navbar is now flexbox.

You can use mr-auto for auto right margin on the 1st (left) navbar-nav. Alternatively, ml-auto could be used on the 2nd (right) navbar-nav , or if you just have a single navbar-nav.

    <div class="collapse navbar-collapse justify-content-end" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Contact</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>

        </li>
      </ul>
    </div>
  </div>
</nav>

Or when you have 2 navbar-navs, use justify-content-between in navbar-collapse would work to even the space between the navbar-navs:

 <div class="navbar-collapse collapse justify-content-between">
     <ul class="navbar-nav mr-auto">
               ..
     </ul>
     <ul class="navbar-nav">
           ..
     </ul>
 </div>

Update for Bootstrap 4.0 and newer

As of Bootstrap 4 beta, ml-auto will still work to push items to the right. Just be aware the the navbar-toggleable- classes have changed to navbar-expand-*

Updated navbar right for Bootstrap 4

Another frequent Bootstrap 4 Navbar right alignment scenario includes a button on the right that remains outside the mobile collapse nav so that it is always shown at all widths.

Right align button that is always visible

Related: Bootstrap NavBar with left, center or right aligned items

Update for Bootstrap 5 (see this question). ml-auto has been replaced with ms-auto to represent start instead of left.

Use a static AutoResetEvent in your spawned threads to call back to the main thread using the Set() method. This guy has a fairly good demo in SO on how to use it.

AutoResetEvent clarification

Download the file and from the same directory run docker build -t nodebb .

This will give you an image on your local machine that's named nodebb that you can launch an container from with docker run -d nodebb (you can change nodebb to your own name).

Vlad's code is overquoted. Should be:

MY_PATH=`dirname "$0"`
MY_PATH=`( cd "$MY_PATH" && pwd )`

The topic is quite old but still relevant in enterprise business contexts. I tried to avoid to touch the xsds in order to easily update them in the future. Here are my solutions..

1. Mostly xjc:simple is sufficient

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jxb:bindings version="2.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    jxb:extensionBindingPrefixes="xjc">

    <jxb:globalBindings>
        <xjc:simple/> <!-- adds @XmlRootElement annotations -->
    </jxb:globalBindings>

</jxb:bindings>

It will mostly create XmlRootElements for importing xsd definitions.

2. Divide your jaxb2-maven-plugin executions

I have encountered that it makes a huge difference if you try to generate classes from multiple xsd definitions instead of a execution definition per xsd.

So if you have a definition with multiple <source>'s, than just try to split them:

          <execution>
            <id>xjc-schema-1</id>
            <goals>
              <goal>xjc</goal>
            </goals>
            <configuration>
              <xjbSources>
                <xjbSource>src/main/resources/xsd/binding.xjb</xjbSource>
              </xjbSources>
              <sources>
                <source>src/main/resources/xsd/definition1/</source>
              </sources>
              <clearOutputDir>false</clearOutputDir>
            </configuration>
          </execution>

          <execution>
            <id>xjc-schema-2</id>
            <goals>
              <goal>xjc</goal>
            </goals>
            <configuration>
              <xjbSources>
                <xjbSource>src/main/resources/xsd/binding.xjb</xjbSource>
              </xjbSources>
              <sources>
                <source>src/main/resources/xsd/definition2/</source>
              </sources>
              <clearOutputDir>false</clearOutputDir>
            </configuration>
          </execution>

The generator will not catch the fact that one class might be sufficient and therefore create custom classes per execution. And thats exactly what I need ;).

Knowing the differences between SVG and Canvas would be helpful in selecting the right one.

Canvas

• Resolution dependent
• No support for event handlers
• Poor text rendering capabilities
• You can save the resulting image as .png or .jpg
• Well suited for graphic-intensive games

SVG

• Resolution independent
• Support for event handlers
• Best suited for applications with large rendering areas (Google Maps)
• Slow rendering if complex (anything that uses the DOM a lot will be slow)
• Not suited for game application

Two warnings

Avoid 301 and prefer modern 303 or 307 response status codes.

Avoid 301

Think carefully if you really need the permanent redirect indicated as [R=301] because if you decide to change it later, then the previous visitors of the page will continue to see the page of the original redirection.

The permanent redirection information is frequently stored in the browser's cache and, in general, it is difficult to eliminate (reload the page do not solve the problem). Your website visitors will be stuck in the previous redirect "forever".

Avoid 302 too

The new version of the HTTP protocol (v1.1) added two new response status codes that can be used instead of 302.

• 303 URL redirection but demanding to change the type of request to GET.
• 307 URL Redirection but demanding to keep the type of request as initially sent.

You can still use the code 302 (non-permanent redirection) although it is considered ambiguous. In any case, most browsers implement 302 in the same way the new 303 code instructs.

You can check Long object for null value with longValue == null , you can use longValue == 0L for long (primitive), because default value of long is 0L, but it's result will be true if longValue is zero too

I think you should be able to follow the method used in this post. It looks really ugly, but I would think you could do it twice and get the result you want.

I wonder if this is actually a case where you'd be better off using DataContext.ExecuteCommand(...) instead of converting to linq.

When I was learning venv I created a script to remind me how to activate it.

#!/bin/sh
# init_venv.sh
if [ -d "./bin" ];then
  echo "[info] Ctrl+d to deactivate"
  bash -c ". bin/activate; exec /usr/bin/env bash --rcfile <(echo 'PS1=\"(venv)\${PS1}\"') -i"
fi

This has the advantage that it changes the prompt.

[Edit]

As noted in comments above, while still on some UA implementations, readAsBinaryString method didn't made its way to the specs and should not be used in production. Instead, use readAsArrayBuffer and loop through it's buffer to get back the binary string :

document.querySelector('input').addEventListener('change', function() {_x000D_
_x000D_
  var reader = new FileReader();_x000D_
  reader.onload = function() {_x000D_
_x000D_
    var arrayBuffer = this.result,_x000D_
      array = new Uint8Array(arrayBuffer),_x000D_
      binaryString = String.fromCharCode.apply(null, array);_x000D_
_x000D_
    console.log(binaryString);_x000D_
_x000D_
  }_x000D_
  reader.readAsArrayBuffer(this.files[0]);_x000D_
_x000D_
}, false);

<input type="file" />_x000D_
<div id="result"></div>

For a more robust way to convert your arrayBuffer in binary string, you can refer to this answer.

[old answer] _(modified)

Yes, the file API does provide a way to convert your File, in the <input type="file"/> to a binary string, thanks to the FileReader Object and its method readAsBinaryString.
[But don't use it in production !]

document.querySelector('input').addEventListener('change', function(){_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
        var binaryString = this.result;_x000D_
        document.querySelector('#result').innerHTML = binaryString;_x000D_
        }_x000D_
    reader.readAsBinaryString(this.files[0]);_x000D_
  }, false);

<input type="file"/>_x000D_
<div id="result"></div>

If you want an array buffer, then you can use the readAsArrayBuffer() method :

document.querySelector('input').addEventListener('change', function(){_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
        var arrayBuffer = this.result;_x000D_
      console.log(arrayBuffer);_x000D_
        document.querySelector('#result').innerHTML = arrayBuffer + '  '+arrayBuffer.byteLength;_x000D_
        }_x000D_
    reader.readAsArrayBuffer(this.files[0]);_x000D_
  }, false);

<input type="file"/>_x000D_
<div id="result"></div>

unsorted_list.sort(key=lambda x: x[3])

This problem can occur if you have altogether too much stuff being started when the server is started -- or if you are in debug mode and stepping through the initialization sequence. In eclipse, changing the start-timeout by 'opening' the tomcat server entry 'Servers view' tab of the Debug Perspective is convenient. In some situations it is useful to know where this setting is 'really' stored.

Tomcat reads this setting from the element in the element in the servers.xml file. This file is stored in the .metatdata/.plugins/org.eclipse.wst.server.core directory of your eclipse workspace, ie:

//.metadata/.plugins/org.eclipse.wst.server.core/servers.xml

There are other juicy configuration files for Eclipse plugins in other directories under .metadata/.plugins as well.

Here's an example of the servers.xml file, which is what is changed when you edit the tomcat server configuration through the Eclipse GUI:

Note the 'start-timeout' property that is set to a good long 1200 seconds above.

If you are using Bootstrap you can also use a responsive embed. This will fully automate making the video(s) responsive.

http://getbootstrap.com/components/#responsive-embed

There's some example code below.

<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

You guys are completely right numbers can only go in the numeric field. I use the exact same thing as already listed with a bit of css styling on a span tag:

<span>$</span><input type="number" min="0.01" step="0.01" max="2500" value="25.67">

Then add a bit of styling magic:

span{
  position:relative;
  margin-right:-20px
}
input[type='number']{
  padding-left:20px;
  text-align:left;
}

I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application

Excerpt from the linked page:

Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:

Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.

Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the Include method.

Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace Collection(x => x.Courses) with Reference(x => x.Administrator).) Typically you'd use explicit loading only when you've turned lazy loading off.

Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.

For me, I had side-sync enabled and active. Closing it imediately made the issue go away. It might be worth closing this or any other communication between PC and device

The string created by calling Hash#inspect can be turned back into a hash by calling eval on it. However, this requires the same to be true of all of the objects in the hash.

If I start with the hash {:a => Object.new}, then its string representation is "{:a=>#<Object:0x7f66b65cf4d0>}", and I can't use eval to turn it back into a hash because #<Object:0x7f66b65cf4d0> isn't valid Ruby syntax.

However, if all that's in the hash is strings, symbols, numbers, and arrays, it should work, because those have string representations that are valid Ruby syntax.

Just wanted to throw out a real use case that demonstrates idempotence. In JavaScript, say you are defining a bunch of model classes (as in MVC model). The way this is often implemented is functionally equivalent to something like this (basic example):

function model(name) {
  function Model() {
    this.name = name;
  }

  return Model;
}

You could then define new classes like this:

var User = model('user');
var Article = model('article');

But if you were to try to get the User class via model('user'), from somewhere else in the code, it would fail:

var User = model('user');
// ... then somewhere else in the code (in a different scope)
var User = model('user');

Those two User constructors would be different. That is,

model('user') !== model('user');

To make it idempotent, you would just add some sort of caching mechanism, like this:

var collection = {};

function model(name) {
  if (collection[name])
    return collection[name];

  function Model() {
    this.name = name;
  }

  collection[name] = Model;
  return Model;
}

By adding caching, every time you did model('user') it will be the same object, and so it's idempotent. So:

model('user') === model('user');

Just do Ctrl + Enter inside the text box

Try this:

var obj = {
    a: "foo",
    b: obj
};

var circular_replacer = (value) => {
    var seen = [];
    if (value != null && typeof value == "object") {
        if (seen.indexOf(value) >= 0) return;
        seen.push(value);
    }
    return value;
};

obj = circular_replacer(obj);

First install TortoiseSVN. During installation follow this steps

1.Run the the TortoiseSVN Installer.

2.If you have already installed svn, "Select the option to Modify".

3.select the check box "Install Command line client tools on to the local harddrive".

4.Add C:\Program Files\TortoiseSVN\bin to your Path environment variable or press CTRL+ALT+S in android studio. Then go to "Version Control"-> Subversion -> General -> Check the Checkbox "use commmand line client" and set the path to C:\Program Files\TortoiseSVN\bin\svn.exe

5.Restart IntelliJ.

In Android studio1.5 version when you try to add the file in your project,
android studio will ask for a pop like "schedule for Addition"
to subversion?. select the check box (Remember, don't ask again) and click "yes". 
After this whatever the file you add or remove to your project it will automatically
synced to your svn repository. suppose if you didn't get that dialog, but you want to
add the newly added .png or xml file to svn means you can manually select those files 
which you have added (the newly added file will be in red color) right click 
on that file -> subversion -> Add to VCS or simply select the file and use (CTRL+ALT+A).

In the image green color(logo_actionbar) represents to file was already added to svn, red represents yet to add in svn. cool..!

If you want to change the "Schedule for Addition" setting means, Go to Settings -> Version Control -> Confirmation -> When files are created
Choose Show options before adding to version control

http sends/receives data as strings... this is just the way things are. You are looking to parse the string as json.

var jsonObject = JSON.parse(data);

How to parse JSON using Node.js?

try

with open(f"{os.path.dirname(sys.argv[0])}/data/test.csv", newline='') as f:

psexec \\RemoteComputer cmd.exe

or use ssh or TeamViewer or RemoteDesktop!

Inject custom postgresql.conf into postgres Docker container

The default postgresql.conf file lives within the PGDATA dir (/var/lib/postgresql/data), which makes things more complicated especially when running postgres container for the first time, since the docker-entrypoint.sh wrapper invokes the initdb step for PGDATA dir initialization.

To customize PostgreSQL configuration in Docker consistently, I suggest using config_file postgres option together with Docker volumes like this:

Production database (PGDATA dir as Persistent Volume)

docker run -d \
-v $CUSTOM_CONFIG:/etc/postgresql.conf \
-v $CUSTOM_DATADIR:/var/lib/postgresql/data \
-e POSTGRES_USER=postgres \
-p 5432:5432 \
--name postgres \
postgres:9.6 postgres -c config_file=/etc/postgresql.conf

Testing database (PGDATA dir will be discarded after docker rm)

docker run -d \
-v $CUSTOM_CONFIG:/etc/postgresql.conf \
-e POSTGRES_USER=postgres \
--name postgres \
postgres:9.6 postgres -c config_file=/etc/postgresql.conf

Debugging

1. Remove the -d (detach option) from docker run command to see the server logs directly.

2. Connect to the postgres server with psql client and query the configuration:

   docker run -it --rm --link postgres:postgres postgres:9.6 sh -c 'exec psql -h $POSTGRES_PORT_5432_TCP_ADDR -p $POSTGRES_PORT_5432_TCP_PORT -U postgres'
   
   psql (9.6.0)
   Type "help" for help.
   
   postgres=# SHOW all;
   

As a late corolloary to the earlier answers here, you probably end up in situations where you want some but not all variables to be interpolated. You can solve that by using backslashes to escape dollar signs and backticks; or you can put the static text in a variable.

Name='Rich Ba$tard'
dough='$$$dollars$$$'
cat <<____HERE
$Name, you can win a lot of $dough this week!
Notice that \`backticks' need escaping if you want
literal text, not `pwd`, just like in variables like
\$HOME (current value: $HOME)
____HERE

Demo: https://ideone.com/rMF2XA

Note that any of the quoting mechanisms -- \____HERE or "____HERE" or '____HERE' -- will disable all variable interpolation, and turn the here-document into a piece of literal text.

A common task is to combine local variables with script which should be evaluated by a different shell, programming language, or remote host.

local=$(uname)
ssh -t remote <<:
    echo "$local is the value from the host which ran the ssh command"
    # Prevent here doc from expanding locally; remote won't see backslash
    remote=\$(uname)
    # Same here
    echo "\$remote is the value from the host we ssh:ed to"
:

I used the command pattern that @jk. mentioned, adding a return type:

public interface Callable<I, O> {

    public O call(I input);   
}

Here is the BESTEST way to send emails using PHPmailer library, this is the only method that works for me.

require_once 'mailer/class.phpmailer.php';
    $mail = new PHPMailer(); // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true; // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465; // or 587
    $mail->IsHTML(true);
    $mail->Username = "[email protected]";
    $mail->Password = "xxxxxxx";
    $mail->SetFrom("[email protected]");
    $mail->AddAddress($to);
    $logfile = dirname(dirname(__FILE__)) . '/mail.log';
    try {
        $mail->Body = $message;
        $mail->Subject = $subject;


        file_put_contents($logfile, "Content: \n", FILE_APPEND);
        file_put_contents($logfile, $message . "\n\n", FILE_APPEND);

        if(!$mail->Send()) {
            echo "Mailer Error: " . $mail->ErrorInfo;
        } else {
            echo "Email has been sent";
        }
    } catch (Exception $e) {
        #print_r($e->getMessage());
        file_put_contents($logfile, "Error: \n", FILE_APPEND);
        file_put_contents($logfile, $e->getMessage() . "\n", FILE_APPEND);
        file_put_contents($logfile, $e->getTraceAsString() . "\n\n", FILE_APPEND);
    }

By definition a segue can't really exist independently of a storyboard. It's even there in the name of the class: UIStoryboardSegue. You don't create segues programmatically - it is the storyboard runtime that creates them for you. You can normally call performSegueWithIdentifier: in your view controller's code, but this relies on having a segue already set up in the storyboard to reference.

What I think you are asking though is how you can create a method in your common view controller (base class) that will transition to a new view controller, and will be inherited by all derived classes. You could do this by creating a method like this one to your base class view controller:

- (IBAction)pushMyNewViewController
{
    MyNewViewController *myNewVC = [[MyNewViewController alloc] init];

    // do any setup you need for myNewVC

    [self presentModalViewController:myNewVC animated:YES];
}

and then in your derived class, call that method when the appropriate button is clicked or table row is selected or whatever.

I liked Alex's answer, because a filter is exactly an if applied to a list, so if you want to explore a subset of a list given a condition, this seems to be the most natural way

mylist = [1,2,3,4,5]
another_list = [2,3,4]

wanted = lambda x:x in another_list

for x in filter(wanted, mylist):
    print(x)

this method is useful for the separation of concerns, if the condition function changes, the only code to fiddle with is the function itself

mylist = [1,2,3,4,5]

wanted = lambda x:(x**0.5) > 10**0.3

for x in filter(wanted, mylist):
    print(x)

The generator method seems better when you don't want members of the list, but a modification of said members, which seems more fit to a generator

mylist = [1,2,3,4,5]

wanted = lambda x:(x**0.5) > 10**0.3

generator = (x**0.5 for x in mylist if wanted(x))

for x in generator:
    print(x)

Also, filters work with generators, although in this case it isn't efficient

mylist = [1,2,3,4,5]

wanted = lambda x:(x**0.5) > 10**0.3

generator = (x**0.9 for x in mylist)

for x in filter(wanted, generator):
    print(x)

But of course, it would still be nice to write like this:

mylist = [1,2,3,4,5]

wanted = lambda x:(x**0.5) > 10**0.3

# for x in filter(wanted, mylist):
for x in mylist if wanted(x):
    print(x)

This works across year and month changes.

Date.prototype.GetFirstDayOfWeek = function() {
    return (new Date(this.setDate(this.getDate() - this.getDay())));
}

Date.prototype.GetLastDayOfWeek = function() {
    return (new Date(this.setDate(this.getDate() - this.getDay() +6)));
}

var today = new Date();

alert(today.GetFirstDayOfWeek());

alert(today.GetLastDayOfWeek());

You have entered wrong port number 3360 instead of 3306. You dont need to write database port number if you are using daefault (3306 in case of MySQL)

First import NumberFormat. Then add this:

NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();

This will give you two decimal places and put a dollar sign if it's dealing with currency.

import java.text.NumberFormat;
public class Payroll 
{
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) 
    {
    int hoursWorked = 80;
    double hourlyPay = 15.52;

    double grossPay = hoursWorked * hourlyPay;
    NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();

    System.out.println("Your gross pay is " + currencyFormatter.format(grossPay));
    }

}

A checksum comparison will most likely be slower than a byte-by-byte comparison.

In order to generate a checksum, you'll need to load each byte of the file, and perform processing on it. You'll then have to do this on the second file. The processing will almost definitely be slower than the comparison check.

As for generating a checksum: You can do this easily with the cryptography classes. Here's a short example of generating an MD5 checksum with C#.

However, a checksum may be faster and make more sense if you can pre-compute the checksum of the "test" or "base" case. If you have an existing file, and you're checking to see if a new file is the same as the existing one, pre-computing the checksum on your "existing" file would mean only needing to do the DiskIO one time, on the new file. This would likely be faster than a byte-by-byte comparison.

In Python 3.8, you can print out the contents of an object by using the __dict__. For example,

class Person():
   pass

person = Person()

## set attributes
person.first = 'Oyinda'
person.last = 'David'

## to see the content of the object
print(person.__dict__)  

{"first": "Oyinda", "last": "David"}

If you really need the SelectionChanged event, then the best answer is SwDevMan81's answer. However, if you are starting with WPF, then you might want to learn how to do things the WPF way, which is different than the old Windows Forms days that used to rely on events like SelectionChanged, with WPF and Model View ViewModel pattern, you should use bindings. Here is a code example:

// In the Views folder: /Views/MyWindow.xaml:
// ...
<ComboBox ItemsSource="{Binding MyViewModel.MyProperties, RelativeSource={RelativeSource AncestorType=Window}}"
         SelectedItem="{Binding MyViewModel.MyProperty  , RelativeSource={RelativeSource AncestorType=Window}}" />
// ...



// In the Views folder: /Views/MyWindow.xaml.cs:

HTTP version 1.1 added a special HTTP method, CONNECT - intended to create the SSL tunnel, including the necessary protocol handshake and cryptographic setup.
The regular requests thereafter all get sent wrapped in the SSL tunnel, headers and body inclusive.

ThiefMaster's answer is 100% correct, although I came across a similar problem where I needed to fetch a property from a nested object (object within an object), so as an alternative to his answer, you can create a recursive solution that will allow you to define a nomenclature to grab any property, regardless of depth:

function fetchFromObject(obj, prop) {

    if(typeof obj === 'undefined') {
        return false;
    }

    var _index = prop.indexOf('.')
    if(_index > -1) {
        return fetchFromObject(obj[prop.substring(0, _index)], prop.substr(_index + 1));
    }

    return obj[prop];
}

Where your string reference to a given property ressembles property1.property2

The amount of memory allocated for the Java process is pretty much on-par with what I would expect. I've had similar problems running Java on embedded/memory limited systems. Running any application with arbitrary VM limits or on systems that don't have adequate amounts of swap tend to break. It seems to be the nature of many modern apps that aren't design for use on resource-limited systems.

You have a few more options you can try and limit your JVM's memory footprint. This might reduce the virtual memory footprint:

-XX:ReservedCodeCacheSize=32m Reserved code cache size (in bytes) - maximum code cache size. [Solaris 64-bit, amd64, and -server x86: 48m; in 1.5.0_06 and earlier, Solaris 64-bit and and64: 1024m.]

-XX:MaxPermSize=64m Size of the Permanent Generation. [5.0 and newer: 64 bit VMs are scaled 30% larger; 1.4 amd64: 96m; 1.3.1 -client: 32m.]

Also, you also should set your -Xmx (max heap size) to a value as close as possible to the actual peak memory usage of your application. I believe the default behavior of the JVM is still to double the heap size each time it expands it up to the max. If you start with 32M heap and your app peaked to 65M, then the heap would end up growing 32M -> 64M -> 128M.

You might also try this to make the VM less aggressive about growing the heap:

-XX:MinHeapFreeRatio=40 Minimum percentage of heap free after GC to avoid expansion.

Also, from what I recall from experimenting with this a few years ago, the number of native libraries loaded had a huge impact on the minimum footprint. Loading java.net.Socket added more than 15M if I recall correctly (and I probably don't).

Replace your jquery files with followings :

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script> <script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script>

strchr for searching a char from start (strrchr from the end):

  char str[] = "This is a sample string";

  if (strchr(str, 'h') != NULL) {
      /* h is in str */
  }

In Angular 2+, try the @Input decorator

It allows for some nice property binding between parent and child components.

First create a global variable in the parent to hold the object/property that will be passed to the child.

Next create a global variable in the child to hold the object/property passed from the parent.

Then in the parent html, where the child template is used, add square brackets notation with the name of the child variable, then set it equal to the name of the parent variable. Example:

<child-component-template [childVariable] = parentVariable>
</child-component-template>

Finally, where the child property is defined in the child component, add the Input decorator:

@Input()
public childVariable: any

When your parent variable is updated, it should pass the updates to the child component, which will update its html.

Also, to trigger a function in the child component, take a look at ngOnChanges.

This exception may also occur if you are using Sockets on one side and SSLSockets on the other. Consistency is important.

Check the below lines are present in your web.config file

<system.web> <httpRuntime requestPathInvalidCharacters="" /> </system.web>

One way is to convert your array to an object and use it in scope (simulation of an array). This way has the benefit of maintaining the template.

$scope.telephone = {};
for (var i = 0, l = $scope.phones.length; i < l; i++) {
  $scope.telephone[i.toString()] = $scope.phone[i];
}

<input type="text" ng-model="telephone[0.toString()]" />
<input type="text" ng-model="telephone[1.toString()]" />

and on save, change it back.

$scope.phones = [];
for (var i in $scope.telephone) {
  $scope.phones[parseInt(i)] = $scope.telephone[i];
}

Dim strPath As String = System.IO.Path.GetDirectoryName( _
    System.Reflection.Assembly.GetExecutingAssembly().CodeBase)

A small note on custom attributes: HTML5 allows all kind of custom attributes, as long as they are prefixed with the particle data-, i.e. data-my-attribute="true".

I think there must have been some change in AD group used to authenticate against the database. Add the web server name, in the format domain\webservername$, to the AD group that had access to the database. In addition, also try to set the web.config attribute to "false". Hope it helps.

EDIT: Going by what you have edited.. it most probably indicate that the authentication protocol of your SQL Server has fallen back from Kerberos(Default, if you were using Windows integrated authentication) to NTLM. For using Kerberos service principal name (SPN) must be registered in the Active Directory directory service. Service Principal Name(SPNs) are unique identifiers for services running on servers. Each service that will use Kerberos authentication needs to have an SPN set for it so that clients can identify the service on the network. It is registered in Active Directory under either a computer account or a user account. Although the Kerberos protocol is the default, if the default fails, authentication process will be tried using NTLM.

In your scenario, client must be making tcp connection, and it is most likely running under LocalSystem account, and there is no SPN registered for SQL instance, hence, NTLM is used, however, LocalSystem account inherits from System Context instead of a true user-based context, thus, failed as 'ANONYMOUS LOGON'.

To resolve this ask your domain administrator to manually register SPN if your SQL Server running under a domain user account. Following links might help you more:

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

Here is example of using aggregation API. To complicate the case we're grouping by case-insensitive words from array property of the document.

db.articles.aggregate([
    {
        $match: {
            keywords: { $not: {$size: 0} }
        }
    },
    { $unwind: "$keywords" },
    {
        $group: {
            _id: {$toLower: '$keywords'},
            count: { $sum: 1 }
        }
    },
    {
        $match: {
            count: { $gte: 2 }
        }
    },
    { $sort : { count : -1} },
    { $limit : 100 }
]);

that give result such as

{ "_id" : "inflammation", "count" : 765 }
{ "_id" : "obesity", "count" : 641 }
{ "_id" : "epidemiology", "count" : 617 }
{ "_id" : "cancer", "count" : 604 }
{ "_id" : "breast cancer", "count" : 596 }
{ "_id" : "apoptosis", "count" : 570 }
{ "_id" : "children", "count" : 487 }
{ "_id" : "depression", "count" : 474 }
{ "_id" : "hiv", "count" : 468 }
{ "_id" : "prognosis", "count" : 428 }

A multiple extension aware procedure. Works for str and unicode paths. Works in Python 2 and 3.

import os

def file_base_name(file_name):
    if '.' in file_name:
        separator_index = file_name.index('.')
        base_name = file_name[:separator_index]
        return base_name
    else:
        return file_name

def path_base_name(path):
    file_name = os.path.basename(path)
    return file_base_name(file_name)

Behavior:

>>> path_base_name('file')
'file'
>>> path_base_name(u'file')
u'file'
>>> path_base_name('file.txt')
'file'
>>> path_base_name(u'file.txt')
u'file'
>>> path_base_name('file.tar.gz')
'file'
>>> path_base_name('file.a.b.c.d.e.f.g')
'file'
>>> path_base_name('relative/path/file.ext')
'file'
>>> path_base_name('/absolute/path/file.ext')
'file'
>>> path_base_name('Relative\\Windows\\Path\\file.txt')
'file'
>>> path_base_name('C:\\Absolute\\Windows\\Path\\file.txt')
'file'
>>> path_base_name('/path with spaces/file.ext')
'file'
>>> path_base_name('C:\\Windows Path With Spaces\\file.txt')
'file'
>>> path_base_name('some/path/file name with spaces.tar.gz.zip.rar.7z')
'file name with spaces'

You can try as.vector(t(test)). Please note that, if you want to do it by columns you should use unlist(test).

Here's the result I finally ended up using. It's a modified version of the classes by dgorissen above.

Are you targeting the .NET 4 framework or the .NET 4 Client Profile?

If you're targeting the latter, you won't find that class. You also may be missing a reference, likely to an extensions dll.

As your edit points out, you can use two separate branches to store the two separate directories. This does keep them both in the same repository, but you still can't have commits spanning both directory trees. If you have a change in one that requires a change in the other, you'll have to do those as two separate commits, and you open up the possibility that a pair of checkouts of the two directories can go out of sync.

If you want to treat the pair of directories as one unit, you can use 'wordpress/wp-content' as the root of your repo and use .gitignore file at the top level to ignore everything but the two subdirectories of interest. This is probably the most reasonable solution at this point.

Sparse checkouts have been allegedly coming for two years now, but there's still no sign of them in the git development repo, nor any indication that the necessary changes will ever arrive there. I wouldn't count on them.

All solutions work great, except when applied in programming languages that closures (e.g. Coda, Excel, Spreadsheet's REGEXREPLACE).

Two original solutions of mine below use only 1 concatenation and 1 regex.

Method #1: Lookup for replacement values

The idea is to append replacement values if they are not already in the string. Then, using a single regex, we perform all needed replacements:

var str = "I have a cat, a dog, and a goat.";
str = (str+"||||cat,dog,goat").replace(
   /cat(?=[\s\S]*(dog))|dog(?=[\s\S]*(goat))|goat(?=[\s\S]*(cat))|\|\|\|\|.*$/gi, "$1$2$3");
document.body.innerHTML = str;

Explanations:

• cat(?=[\s\S]*(dog)) means that we look for "cat". If it matches, then a forward lookup will capture "dog" as group 1, and "" otherwise.
• Same for "dog" that would capture "goat" as group 2, and "goat" that would capture "cat" as group 3.
• We replace with "$1$2$3" (the concatenation of all three groups), which will always be either "dog", "cat" or "goat" for one of the above cases
• If we manually appended replacements to the string like str+"||||cat,dog,goat", we remove them by also matching \|\|\|\|.*$, in which case the replacement "$1$2$3" will evaluate to "", the empty string.

Method #2: Lookup for replacement pairs

One problem with Method #1 is that it cannot exceed 9 replacements at a time, which is the maximum number of back-propagation groups. Method #2 states not to append just replacement values, but replacements directly:

var str = "I have a cat, a dog, and a goat.";
str = (str+"||||,cat=>dog,dog=>goat,goat=>cat").replace(
   /(\b\w+\b)(?=[\s\S]*,\1=>([^,]*))|\|\|\|\|.*$/gi, "$2");
document.body.innerHTML = str;

Explanations:

• (str+"||||,cat=>dog,dog=>goat,goat=>cat") is how we append a replacement map to the end of the string.
• (\b\w+\b) states to "capture any word", that could be replaced by "(cat|dog|goat) or anything else.
• (?=[\s\S]*...) is a forward lookup that will typically go to the end of the document until after the replacement map.
  • ,\1=> means "you should find the matched word between a comma and a right arrow"
  • ([^,]*) means "match anything after this arrow until the next comma or the end of the doc"
• |\|\|\|\|.*$ is how we remove the replacement map.

The best and simplest way to read a line from a console is using the getchar() function, whereby you will store one character at a time in an array.

{
char message[N];        /* character array for the message, you can always change the character length */
int i = 0;          /* loop counter */

printf( "Enter a message: " );
message[i] = getchar();    /* get the first character */
while( message[i] != '\n' ){
    message[++i] = getchar(); /* gets the next character */
}

printf( "Entered message is:" );
for( i = 0; i < N; i++ )
    printf( "%c", message[i] );

return ( 0 );

}

Are we talking about standard java.io.FileReader? Won't work, but it's not hard without it.

/src/main/resources maven directory contents are placed in the root of your CLASSPATH, so you can simply retrieve it using:

InputStream is = getClass().getResourceAsStream("/storedProcedures.sql");

If the result is not null (resource not found), feel free to wrap it in a reader:

Reader reader = new InputStreamReader(is);

I don't try changing sequence via setval. But using ALTER I was issued how to write sequence name properly. And this only work for me:

1. Check required sequence name using SELECT * FROM information_schema.sequences;

2. ALTER SEQUENCE public."table_name_Id_seq" restart {number};

   In my case it was ALTER SEQUENCE public."Services_Id_seq" restart 8;

Also there is a page on wiki.postgresql.org where describes a way to generate sql script to fix sequences in all database tables at once. Below the text from link:

Save this to a file, say 'reset.sql'

SELECT 'SELECT SETVAL(' ||
       quote_literal(quote_ident(PGT.schemaname) || '.' || quote_ident(S.relname)) ||
       ', COALESCE(MAX(' ||quote_ident(C.attname)|| '), 1) ) FROM ' ||
       quote_ident(PGT.schemaname)|| '.'||quote_ident(T.relname)|| ';'
FROM pg_class AS S,
     pg_depend AS D,
     pg_class AS T,
     pg_attribute AS C,
     pg_tables AS PGT
WHERE S.relkind = 'S'
    AND S.oid = D.objid
    AND D.refobjid = T.oid
    AND D.refobjid = C.attrelid
    AND D.refobjsubid = C.attnum
    AND T.relname = PGT.tablename
ORDER BY S.relname;

Run the file and save its output in a way that doesn't include the usual headers, then run that output. Example:

psql -Atq -f reset.sql -o temp
psql -f temp
rm temp

And the output will be a set of sql commands which look exactly like this:

SELECT SETVAL('public."SocialMentionEvents_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."SocialMentionEvents";
SELECT SETVAL('public."Users_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."Users";

I try to explain it more understandably than the referred PostgreSQL documentation.

Neither TIMESTAMP variants store a time zone (or an offset), despite what the names suggest. The difference is in the interpretation of the stored data (and in the intended application), not in the storage format itself:

• TIMESTAMP WITHOUT TIME ZONE stores local date-time (aka. wall calendar date and wall clock time). Its time zone is unspecified as far as PostgreSQL can tell (though your application may knows what it is). Hence, PostgreSQL does no time zone related conversion on input or output. If the value was entered into the database as '2011-07-01 06:30:30', then no mater in what time zone you display it later, it will still say year 2011, month 07, day 01, 06 hours, 30 minutes, and 30 seconds (in some format). Also, any offset or time zone you specify in the input is ignored by PostgreSQL, so '2011-07-01 06:30:30+00' and '2011-07-01 06:30:30+05' are the same as just '2011-07-01 06:30:30'. For Java developers: it's analogous to java.time.LocalDateTime.

• TIMESTAMP WITH TIME ZONE stores a point on the UTC time line. How it looks (how many hours, minutes, etc.) depends on your time zone, but it always refers to the same "physical" instant (like the moment of an actual physical event). The input is internally converted to UTC, and that's how it's stored. For that, the offset of the input must be known, so when the input contains no explicit offset or time zone (like '2011-07-01 06:30:30') it's assumed to be in the current time zone of the PostgreSQL session, otherwise the explicitly specified offset or time zone is used (as in '2011-07-01 06:30:30+05'). The output is displayed converted to the current time zone of the PostgreSQL session. For Java developers: It's analogous to java.time.Instant (with lower resolution though), but with JDBC and JPA 2.2 you are supposed to map it to java.time.OffsetDateTime (or to java.util.Date or java.sql.Timestamp of course).

Some say that both TIMESTAMP variations store UTC date-time. Kind of, but it's confusing to put it that way in my opinion. TIMESTAMP WITHOUT TIME ZONE is stored like a TIMESTAMP WITH TIME ZONE, which rendered with UTC time zone happens to give the same year, month, day, hours, minutes, seconds, and microseconds as they are in the local date-time. But it's not meant to represent the point on the time line that the UTC interpretation says, it's just the way the local date-time fields are encoded. (It's some cluster of dots on the time line, as the real time zone is not UTC; we don't know what it is.)

As already stated this is not something that browsers support.

If you aren't coming up with the styles dynamically (i.e. pulling them out of a database or something) you should be able to work around this by adding a class to the body of the page.

The css would look something like:

a:hover { background: red; }
.theme1 a:hover { background: blue; }

And the javascript to change this would be something like:

// Look up some good add/remove className code if you want to do this
// This is really simplified

document.body.className += " theme1";  

this is my first code on this site try this

import java.util.Scanner;
public class BATM {

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    String username;
    String password;

    System.out.println("Log in:");
    System.out.println("username: ");
    username = input.next();

    System.out.println("password: ");
    password = input.next();

    //users check = new users(username, password);

    if(username.equals(username) && password.equals(password)) 
        System.out.println("You are logged in");



}

}

Just tested and this works:

public class Coordinates {
    byte red;

    @JsonProperty("r")
    public byte getR() {
      return red;
    }

    @JsonProperty("red")
    public void setRed(byte red) {
      this.red = red;
    }
}

The idea is that method names should be different, so jackson parses it as different fields, not as one field.

Here is test code:

Coordinates c = new Coordinates();
c.setRed((byte) 5);

ObjectMapper mapper = new ObjectMapper();
System.out.println("Serialization: " + mapper.writeValueAsString(c));

Coordinates r = mapper.readValue("{\"red\":25}",Coordinates.class);
System.out.println("Deserialization: " + r.getR());

Result:

Serialization: {"r":5}
Deserialization: 25

You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg

public class MyResult {
    int returnCode;
    String errorMessage;
    // etc
}

public MyResult someMethod() {
    // impl here
}

In case you were struggling to change linetypes, the following answer should be helpful. (This is an addition to the solution by Andy W.)

We will try to extend the learned pattern:

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) +           #red
  geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) +           #blue
  scale_colour_manual(name="Error Bars",values=cols, 
                  guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_linetype_manual(values=line_types)+
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

However, what we get is the following result:

The problem is that the linetype is not merged in the main legend. Note that we did not give any name to the method scale_linetype_manual. The trick which works here is to give it the same name as what you used for naming scale_colour_manual. More specifically, if we change the corresponding line to the following we get the desired result:

scale_linetype_manual(name="Error Bars",values=line_types)

Now, it is easy to change the size of the line with the same idea.

Note that the geom_bar has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.

All of these answers are simple and good. However, I always like to add an interactive mode to these scripts so that I can find false positives.

if [[ -n $inInteractiveMode ]]
then
  echo -e -n "$oldFileName => $newFileName\nDo you want to do this change? [Y/n]: "
  read run

  [[ -z $run || "$run" == "y" || "$run" == "Y" ]] && mv "$oldFileName" "$newFileName"
fi

Or make interactive mode the default and add a force flag (-f | --force) for automated scripts or if you're feeling daring. And this doesn't slow you down too much: the default response is "yes, I do want to rename" so you can just hit the enter key at each prompt (because of the ``-z $run\ test.

The component solution and deep-clone solution have their advantages, but also have issues:

1. Sometimes you want to track changes in abstract data - it doesn't always make sense to build components around that data.

2. Deep-cloning your entire data structure every time you make a change can be very expensive.

I think there's a better way. If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
  },
  methods: {
    handleChange (newVal) {
      // Handle changes here!
      console.log(newVal);
    },
  },
  created () {
    this.list.forEach((val) => {
      this.$watch(() => val, this.handleChange, {deep: true});
    });
  },
});

With this structure, handleChange() will receive the specific list item that changed - from there you can do any handling you like.

I have also documented a more complex scenario here, in case you are adding/removing items to your list (rather than only manipulating the items already there).

What about something like this:

for /f %%f in ('curl -s -l -u user:pass ftp://ftp.myftpsite.com/') do curl -O -u user:pass ftp://ftp.myftpsite.com/%%f

Show whitespace characters in Visual Studio Code

change the setting.json, by adding the following codes!

// Place your settings in this file to overwrite default and user settings.
{
    "editor.renderWhitespace": "all"
}

just like this!
(PS: there is no "true" option!, even it also works.)

In additional to the existing answers which suggests using (to show the diff of the third-to-last stash)

git stash show -p stash@{2}

Note that in the git-stash documentation, it is written that

Stashes may also be referenced by specifying just the stash index (e.g. the integer n is equivalent to stash@{n}).

Therefore it's also possible to use (this is equivalent to the command above)

git stash show -p 2

Which should also avoid some Powershell issues.

2nd October 2020: note that many bare-bones approaches are fraught with subtle bugs (eg. whitespace, implicit partial parsing, radix, coercion of arrays etc.) that many of the answers here fail to take into account. The following implementation might work for you, but note that it does not cater for number separators other than the decimal point ".":

function isNumeric(str) {
  if (typeof str != "string") return false // we only process strings!  
  return !isNaN(str) && // use type coercion to parse the _entirety_ of the string (`parseFloat` alone does not do this)...
         !isNaN(parseFloat(str)) // ...and ensure strings of whitespace fail
}

To check if a variable (including a string) is a number, check if it is not a number:

This works regardless of whether the variable content is a string or number.

isNaN(num)         // returns true if the variable does NOT contain a valid number

Examples

isNaN(123)         // false
isNaN('123')       // false
isNaN('1e10000')   // false (This translates to Infinity, which is a number)
isNaN('foo')       // true
isNaN('10px')      // true

Of course, you can negate this if you need to. For example, to implement the IsNumeric example you gave:

function isNumeric(num){
  return !isNaN(num)
}

To convert a string containing a number into a number:

Only works if the string only contains numeric characters, else it returns NaN.

+num               // returns the numeric value of the string, or NaN 
                   // if the string isn't purely numeric characters

Examples

+'12'              // 12
+'12.'             // 12
+'12..'            // NaN
+'.12'             // 0.12
+'..12'            // NaN
+'foo'             // NaN
+'12px'            // NaN

To convert a string loosely to a number

Useful for converting '12px' to 12, for example:

parseInt(num)      // extracts a numeric value from the 
                   // start of the string, or NaN.

Examples

parseInt('12')     // 12
parseInt('aaa')    // NaN
parseInt('12px')   // 12
parseInt('foo2')   // NaN      These last two may be different
parseInt('12a5')   // 12       from what you expected to see. 

Floats

Bear in mind that, unlike +num, parseInt (as the name suggests) will convert a float into an integer by chopping off everything following the decimal point (if you want to use parseInt() because of this behaviour, you're probably better off using another method instead):

+'12.345'          // 12.345
parseInt(12.345)   // 12
parseInt('12.345') // 12

Empty strings

Empty strings may be a little counter-intuitive. +num converts empty strings or strings with spaces to zero, and isNaN() assumes the same:

+''                // 0
+'   '             // 0
isNaN('')          // false
isNaN('   ')       // false

But parseInt() does not agree:

parseInt('')       // NaN
parseInt('   ')    // NaN

Refer from the answer @user187291, add "isArray" as parameter to make the json nested array to be converted.

data : {
                    staffId : "00000001",
                    Detail : [ {
                        "identityId" : "123456"
                    }, {
                        "identityId" : "654321"
                    } ],

                }

To make the result :

staffId=00000001&Detail[0].identityId=123456&Detail[1].identityId=654321

serialize = function(obj, prefix, isArray) {
        var str = [],p = 0;
        for (p in obj) {
            if (obj.hasOwnProperty(p)) {
                var k, v;
                if (isArray)
                    k = prefix ? prefix + "[" + p + "]" : p, v = obj[p];
                else
                    k = prefix ? prefix + "." + p + "" : p, v = obj[p];

                if (v !== null && typeof v === "object") {
                    if (Array.isArray(v)) {
                        serialize(v, k, true);
                    } else {
                        serialize(v, k, false);
                    }
                } else {
                    var query = k + "=" + v;
                    str.push(query);
                }
            }
        }
        return str.join("&");
    };

    serialize(data, "prefix", false);

Media queries are not supported at all in IE8 and below.

A Javascript based workaround

To add support for IE8, you could use one of several JS solutions. For example, Respond can be added to add media query support for IE8 only with the following code :

<!--[if lt IE 9]>
<script 
   src="respond.min.js">
</script>
<![endif]-->

CSS Mediaqueries is another library that does the same thing. The code for adding that library to your HTML would be identical :

<!--[if lt IE 9]>
<script 
   src="css3-mediaqueries.js">
</script>
<![endif]-->

The alternative

If you don't like a JS based solution, you should also consider adding an IE<9 only stylesheet where you adjust your styling specific to IE<9. For that, you should add the following HTML to your code:

<!--[if lt IE 9]>
<link rel="stylesheet" type="text/css" media="all" href="style-ielt9.css"/>
<![endif]-->

Note :

Technically it's one more alternative: using CSS hacks to target IE<9. It has the same impact as an IE<9 only stylesheet, but you don't need a seperate stylesheet for that. I do not recommend this option, though, as they produce invalid CSS code (which is but one of several reasons why the use of CSS hacks is generally frowned upon today).

Ok guys it can be done easy in photoshop.

Open png photo and then check image -> mode value(i had indexed color). Go image -> mode and check rgb color. Now change your color EASY.

Your groups_main table has a key column named id. I believe you can only use the USING syntax for the join if the groups_fans table has a key column with the same name, which it probably does not. So instead, try this:

LEFT JOIN groups_fans AS m ON m.group_id = g.id

Or replace group_id with whatever the appropriate column name is in the groups_fans table.

This will work:

>>> t = [1,1,2,2,3,3,4,5]
>>> print list(set(t))
[1,2,3,4,5]

However, if you have used "list" or "set" as a variable name you will get the:

TypeError: 'set' object is not callable

eg:

>>> set = [1,1,2,2,3,3,4,5]
>>> print list(set(set))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable

Same error will occur if you have used "list" as a variable name.

Figured it out. Used this instead.

$('.div_class').load('http://en.wikipedia.org/wiki/Cross-origin_resource_sharing #toctitle');

Are you using virtualenv? If yes, deactivate the virtualenv. If you are not using, it is already installed widely (system level). Try to upgrade package.

pip install flake8 --upgrade

The correct function to use is flush().

<html>
<body>
<p>
Hello! I am waiting for the next message...<br />
<?php flush(); sleep(5); ?>
I am the next message!<br />
<?php flush(); sleep(5); ?>
And I am the last message. Good bye.
</p>
</body>
</html>

Please note that there is a "problem" with IE, which only outputs the flushed content when it is at least 256 byte, so your first part of the page needs to be at least 256 byte.

library(lubridate) if your date format is like this '04/24/2017 05:35:00'then change it like below prods.all$Date2<-gsub("/","-",prods.all$Date2) then change the date format parse_date_time(prods.all$Date2, orders="mdy hms")

ALTER PROCEDURE POSMAST

AS
SELECT * FROM TABLE_NAME
WHERE

No, you're not on the right track. A good rule of thumb is: make everything as private as possible. This makes your class more encapsulated, and allows for changing the internals of the class without affecting the code using your class.

If you design your class to be inheritable, then carefully choose what may be overridden and accessible from subclasses, and make that protected (and final, talking of Java, if you want to make it accessible but not overridable). But be aware that, as soon as you accept to have subclasses of your class, and there is a protected field or method, this field or method is part of the public API of the class, and may not be changed later without breaking subclasses.

A class that is not intended to be inherited should be made final (in Java). You might relax some access rules (private to protected, final to non-final) for the sake of unit-testing, but then document it, and make it clear that although the method is protected, it's not supposed to be overridden.

I tried the steps that @KannarKK suggested on ES 2.0.2, however, I could not bring the cluster up and running. Evidently, I figured out something, as I had set tcp port number on Master, on the Slave configuration discovery.zen.ping.unicast.hosts needs Master's port number along with IP address ( tcp port number ) for discovery. So when I try following configuration it works for me.

Node 1

cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
http.port : 9200
tcp.port : 9300
discovery.zen.ping.multicast.enabled: false
# I think unicast.host on master is redundant.
discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2

cluster.name: mycluster
node.name: "node2"
node.master: false
node.data: true
http.port : 9201
tcp.port : 9301
discovery.zen.ping.multicast.enabled: false
# The port number of Node 1
discovery.zen.ping.unicast.hosts: ["node1.example.com:9300"]

When your first argument is null, they're basically the same except that the null coalescing won't output an E_NOTICE when you have an undefined variable. The PHP 7.0 migration docs has this to say:

The null coalescing operator (??) has been added as syntactic sugar for the common case of needing to use a ternary in conjunction with isset(). It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

Here's some example code to demonstrate this:

<?php

$a = null;

print $a ?? 'b'; // b
print "\n";

print $a ?: 'b'; // b
print "\n";

print $c ?? 'a'; // a
print "\n";

print $c ?: 'a'; // Notice: Undefined variable: c in /in/apAIb on line 14
print "\n";

$b = array('a' => null);

print $b['a'] ?? 'd'; // d
print "\n";

print $b['a'] ?: 'd'; // d
print "\n";

print $b['c'] ?? 'e'; // e
print "\n";

print $b['c'] ?: 'e'; // Notice: Undefined index: c in /in/apAIb on line 33
print "\n";

The lines that have the notice are the ones where I'm using the shorthand ternary operator as opposed to the null coalescing operator. However, even with the notice, PHP will give the same response back.

Execute the code: https://3v4l.org/McavC

Of course, this is always assuming the first argument is null. Once it's no longer null, then you end up with differences in that the ?? operator would always return the first argument while the ?: shorthand would only if the first argument was truthy, and that relies on how PHP would type-cast things to a boolean.

So:

$a = false ?? 'f'; // false
$b = false ?: 'g'; // 'g'

would then have $a be equal to false and $b equal to 'g'.

i also got same error , i just change the java version in pom.xml from 11 to 1.8 and it's work fine.

This is a step-by-step procedure to get pkg-config working on Windows, based on my experience, using the info from Oliver Zendel's comment.

I assume here that MinGW was installed to C:\MinGW. There were multiple versions of the packages available, and in each case I just downloaded the latest version.

1. go to http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
2. download the file pkg-config_0.26-1_win32.zip
3. extract the file bin/pkg-config.exe to C:\MinGW\bin
4. download the file gettext-runtime_0.18.1.1-2_win32.zip
5. extract the file bin/intl.dll to C:\MinGW\bin
6. go to http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28
7. download the file glib_2.28.8-1_win32.zip
8. extract the file bin/libglib-2.0-0.dll to C:\MinGW\bin

Now CMake will be able to use pkg-config if it is configured to use MinGW.

There is a helpful function in the psych package.

You should try the following implementation:

psych::describeBy(data$dependentvariable, group = data$groupingvariable)

There are two directories that looks like JDK.

  C:\Program Files\Java\jdk1.7.0_02
  C:\Program Files (x86)\Java\jdk1.7.0_02\

This may be due to both 64 bit and 32 bit JDK installed? What ever may be the case, the java.exe seen by ant.bat should from the JDK. If the JRE's java.exe comes first in the path, that will be used to guess the JDK location.

Put 'C:\Program Files (x86)\Java\jdk1.7.0_02\bin' or 'C:\Program Files\Java\jdk1.7.0_02' as the first argument in the path.

Further steps:

You can take output of ant -diagnostics and look for interesting keys. (assuming Sun/Oracle JDK).

 java.class.path 
 java.library.path
 sun.boot.library.path

(in my case tools.jar appears in java.class.path)

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

I don't think you can at present: see this article on the Postgresql wiki.

The three workarounds from this article are:

1. Recreate the table
2. Add columns and move data
3. Hide the differences with a view.

One thing that jumps out is the operator * overload (returning 0 is a lot friendlier than segfaulting...). Another thing is it doesn't look compatible with storing an address at all. Which, compared to how it goes slinging void*'s and passing NULL results to normal pointers as sentinel values, would obviously reduce the "never forget, it might be a bomb" factor.

try this:

var count_element = $('.element').length

fd.append("image", dataurl);

This will not work. On PHP side you can not save file with this.

Use this code instead:

var blobBin = atob(dataurl.split(',')[1]);
var array = [];
for(var i = 0; i < blobBin.length; i++) {
  array.push(blobBin.charCodeAt(i));
}
var file = new Blob([new Uint8Array(array)], {type: 'image/png', name: "avatar.png"});

fd.append("image", file); // blob file

You need to add the content-disposition header to the response:

 response.StatusCode = HttpStatusCode.OK;
 response.Content = new StreamContent(result);
 response.AppendHeader("content-disposition", "attachment; filename=" + fileName);
 return response;

It solved for me using

                    $class: 'GitSCM',
                    userRemoteConfigs: [[credentialsId: '******',url: ${project_url}]],

            ])

Using virtualenvwrapper function:

wipeenv

See wipeenv documentation

use the nextSibling and previousSibling properties:

<div id="foo1"></div>
<div id="foo2"></div>
<div id="foo3"></div>

document.getElementById('foo2').nextSibling; // #foo3
document.getElementById('foo2').previousSibling; // #foo1

However in some browsers (I forget which) you also need to check for whitespace and comment nodes:

var div = document.getElementById('foo2');
var nextSibling = div.nextSibling;
while(nextSibling && nextSibling.nodeType != 1) {
    nextSibling = nextSibling.nextSibling
}

Libraries like jQuery handle all these cross-browser checks for you out of the box.

I found several functions defined in http://tw1.php.net/unpack are very useful.
They can covert string to byte array and vice versa.

Take byteStr2byteArray() as an example:

<?php
function byteStr2byteArray($s) {
    return array_slice(unpack("C*", "\0".$s), 1);
}

$msg = "abcdefghijk";
$byte_array = byteStr2byteArray($msg);

for($i=0;$i<count($byte_array);$i++)
{
   printf("0x%02x ", $byte_array[$i]);
}
?>

I did something like this. The first 2 zeros are because I don't know what kind of ascii type things this command wants from me. The general feeling I had was to create a temp char array. pass in the wide char array. boom. it works. The +1 ensures that the null terminating character is in the right place.

char tempFilePath[MAX_PATH] = "I want to convert this to wide chars";

int len = strlen(tempFilePath);

// Converts the path to wide characters
    int needed = MultiByteToWideChar(0, 0, tempFilePath, len + 1, strDestPath, len + 1);

When you "call" a function you are basically just telling the program to execute that function. So if you had a function that added two numbers such as:

def add(a,b):
    return a + b

you would call the function like this:

add(3,5)

which would return 8. You can put any two numbers in the parentheses in this case. You can also call a function like this:

answer = add(4,7)

Which would set the variable answer equal to 11 in this case.

Use toString when you need to display the name to the user.

Use name when you need the name for your program itself, e.g. to identify and differentiate between different enum values.

Couple updates to add after working on this subject for a while:

1. all solutions with .is(":hover") break on jQuery 1.9.1
2. The most likely reason to check if the mouse is still over an element is to attempt to prevent events firing over each other. For example, we were having issues with our mouseleave being triggered and completed before our mouseenter event even completed. Of course this was because of a quick mouse movement.

We used hoverIntent https://github.com/briancherne/jquery-hoverIntent to solve the issue for us. Essentially it triggers if the mouse movement is more deliberate. (one thing to note is that it will trigger on both mouse entering an element and leaving - if you only want to use one pass the constructor an empty function )

My minimal approach

For converting negative number to positive & vice-versa

var num = -24;_x000D_
num -= num*2;_x000D_
console.log(num)_x000D_
// result = 24

Sometimes, I wonder why people compare AWS to Heroku. AWS is an IAAS( infrastructure as a service) it clearly speaks how robust and calculative the system is. Heroku, on the other hand, is just a SAAS, it is basically just one fraction of AWS services. So why struggle with setting up AWS when you can ship your first product to the prime using Heroku.

Heroku is free, simple and easy to deploy almost all types of stacks to the web. Heroku is specifically built to bypass all the hassles of shipping your application to a live server in less than no time.

Nevertheless, you may want to deploy your application using any of the tutorials from both parties and compare

Linked list is guaranteed to act in sequential order.

From the documentation

An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted. The user can access elements by their integer index (position in the list), and search for elements in the list.

iterator() Returns an iterator over the elements in this list in proper sequence.

Split your date into year, month, and day components then use Date:

var d = new Date(year, month, day);
d.setMonth(d.getMonth() + 8);

Date will take care of fixing the year.

(This is my third answer because I misunderstood what your code was doing in my original, and then made a small but crucial mistake in my second—hopefully three's a charm.

Edits: Since this seems to be a popular answer, I've made a few modifications to improve its implementation over the years—most not too major. This is so if folks use it as template, it will provide an even better basis.

As others have pointed out, your MemoryError problem is most likely because you're attempting to read the entire contents of huge files into memory and then, on top of that, effectively doubling the amount of memory needed by creating a list of lists of the string values from each line.

Python's memory limits are determined by how much physical ram and virtual memory disk space your computer and operating system have available. Even if you don't use it all up and your program "works", using it may be impractical because it takes too long.

Anyway, the most obvious way to avoid that is to process each file a single line at a time, which means you have to do the processing incrementally.

To accomplish this, a list of running totals for each of the fields is kept. When that is finished, the average value of each field can be calculated by dividing the corresponding total value by the count of total lines read. Once that is done, these averages can be printed out and some written to one of the output files. I've also made a conscious effort to use very descriptive variable names to try to make it understandable.

try:
    from itertools import izip_longest
except ImportError:    # Python 3
    from itertools import zip_longest as izip_longest

GROUP_SIZE = 4
input_file_names = ["A1_B1_100000.txt", "A2_B2_100000.txt", "A1_B2_100000.txt",
                    "A2_B1_100000.txt"]
file_write = open("average_generations.txt", 'w')
mutation_average = open("mutation_average", 'w')  # left in, but nothing written

for file_name in input_file_names:
    with open(file_name, 'r') as input_file:
        print('processing file: {}'.format(file_name))

        totals = []
        for count, fields in enumerate((line.split('\t') for line in input_file), 1):
            totals = [sum(values) for values in
                        izip_longest(totals, map(float, fields), fillvalue=0)]
        averages = [total/count for total in totals]

        for print_counter, average in enumerate(averages):
            print('  {:9.4f}'.format(average))
            if print_counter % GROUP_SIZE == 0:
                file_write.write(str(average)+'\n')

file_write.write('\n')
file_write.close()
mutation_average.close()

You can also use the regex,

import re

eg:-1) word = "3487954"

re.match('^[0-9]*$',word)

eg:-2) word = "3487.954"

re.match('^[0-9\.]*$',word)

eg:-3) word = "3487.954 328"

re.match('^[0-9\.\ ]*$',word)

As you can see all 3 eg means that there is only no in your string. So you can follow the respective solutions given with them.

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

You need to wait for the emulator to full start - takes a few minutes. Once it is fully started (UI on the emulator will change), it should work.

You will need to restart the app after the emulator is running and choose the running emulator when prompted.

You can directly export the query result with export option in the result grig. This export has various options to export. I think this will work.

If you look at the source code for the String class, it actually calls Integer.toString() when you call valueOf().

That being said, Integer.toString() might be a tad faster if the method calls aren't optimized at compile time (which they probably are).

You can define a component and use it wherever.

import React from 'react';
import PropTypes from 'prop-types';

  );
};


DownloadLink.propTypes = {

I tried to update a field with

$table->update(['field' => 'val']);

But it wasn't working, i had to modify my table Model to authorize this field to be edited : add 'field' in the array "protected $fillable"

Hope it will help someone :)

Because you say

struct arg_struct *args = (struct arg_struct *)args;

instead of

struct arg_struct *args = arguments;

It is in the dist folder inside of the project, but only if "Compress WAR File" in the project settings dialog ( build / packaging) ist checked. Before I checked this checkbox there was no dist folder.

You can add values to the HttpWebRequest.Headers collection.

Save it as a .ps1 file and then execute

It took me a while, but I discovered that including the following was what made it possible to change the navbar color:

}

An asynchronously loaded script is likely going to run AFTER the document has been fully parsed and closed. Thus, you can't use document.write() from such a script (well technically you can, but it won't do what you want).

You will need to replace any document.write() statements in that script with explicit DOM manipulations by creating the DOM elements and then inserting them into a particular parent with .appendChild() or .insertBefore() or setting .innerHTML or some mechanism for direct DOM manipulation like that.

For example, instead of this type of code in an inline script:

<div id="container">
<script>
document.write('<span style="color:red;">Hello</span>');
</script>
</div>

You would use this to replace the inline script above in a dynamically loaded script:

var container = document.getElementById("container");
var content = document.createElement("span");
content.style.color = "red";
content.innerHTML = "Hello";
container.appendChild(content);

Or, if there was no other content in the container that you needed to just append to, you could simply do this:

var container = document.getElementById("container");
container.innerHTML = '<span style="color:red;">Hello</span>';

❌

looks like:

?

its good for me :)

You can use the approach @Ken Chan mentions, and add a single line of code after that if you want a specific list of Objects, example:

    session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).setResultTransformer(Transformers.aliasToBean(SomeClazz.class));

List<SomeClazz> objectList = (List<SomeClazz>) criteria.list();

To specifically answer your question Why is the code1 used if we can use code2? I might suggest that the programmer was thinking in a mathematically broader sense. Specifically, perhaps the broader equation is a power equation, and the fact that both first numbers are "2" is more coincidence than mathematical reality. I'd want to make sure that the broader context of the code supports it being

var = x * x * y

In mi and vivo - Using the above solution is not enough. You must also tell the user to add permission manually. You can help them by opening the right location inside phone settings. Varies for different phone models.

If there are multiple certificates in a pfx file (key + corresponding certificate and a CA certificate) then this command worked well for me:

certutil -importpfx c:\somepfx.pfx this works but still a password is needed to be typed in manually for private key. Including -p and "password" cause error too many arguments for certutil on XP

Without explicitly defining the height I determined I need to apply the flex value to the parent and grandparent div elements...

<div style="display: flex;">
<div style="display: flex;">
 <img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>

If you're using a single element (e.g. dead-centered text in a single flex element) use the following:

align-items: center;
display: flex;
justify-content: center;

The vector you are creating is neither row nor column. It actually has 1 dimension only. You can verify that by

• checking the number of dimensions myvector.ndim which is 1
• checking the myvector.shape, which is (3,) (a tuple with one element only). For a row vector is should be (1, 3), and for a column (3, 1)

Two ways to handle this

• create an actual row or column vector
• reshape your current one

You can explicitly create a row or column

row = np.array([    # one row with 3 elements
   [1, 2, 3]
]
column = np.array([  # 3 rows, with 1 element each
    [1],
    [2],
    [3]
])

or, with a shortcut

row = np.r_['r', [1,2,3]]     # shape: (1, 3)
column = np.r_['c', [1,2,3]]  # shape: (3,1)

Alternatively, you can reshape it to (1, n) for row, or (n, 1) for column

row = my_vector.reshape(1, -1)
column = my_vector.reshape(-1, 1)

where the -1 automatically finds the value of n.

Try this:

{
    "ACCOUNT_EXIST": true,
    "MultipleContacts": false
}

This is not an answer, but it's hard to read if I put results in comment.

I get these results with a Mac Pro (Westmere 6-Cores Xeon 3.33 GHz). I compiled it with clang -O3 -msse4 -lstdc++ a.cpp -o a (-O2 get same result).

clang with uint64_t size=atol(argv[1])<<20;

unsigned    41950110000 0.811198 sec    12.9263 GB/s
uint64_t    41950110000 0.622884 sec    16.8342 GB/s

clang with uint64_t size=1<<20;

unsigned    41950110000 0.623406 sec    16.8201 GB/s
uint64_t    41950110000 0.623685 sec    16.8126 GB/s

I also tried to:

1. Reverse the test order, the result is the same so it rules out the cache factor.
2. Have the for statement in reverse: for (uint64_t i=size/8;i>0;i-=4). This gives the same result and proves the compile is smart enough to not divide size by 8 every iteration (as expected).

Here is my wild guess:

The speed factor comes in three parts:

• code cache: uint64_t version has larger code size, but this does not have an effect on my Xeon CPU. This makes the 64-bit version slower.

• Instructions used. Note not only the loop count, but the buffer is accessed with a 32-bit and 64-bit index on the two versions. Accessing a pointer with a 64-bit offset requests a dedicated 64-bit register and addressing, while you can use immediate for a 32-bit offset. This may make the 32-bit version faster.

• Instructions are only emitted on the 64-bit compile (that is, prefetch). This makes 64-bit faster.

The three factors together match with the observed seemingly conflicting results.

Using awk

echo $STRING | awk -v N=$N '{print $N}'

You might looking for the placeholder attribute which will display a grey text in the input field while empty.

From Mozilla Developer Network:

A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the type attribute is text, search, tel, url or email; otherwise it is ignored.

However as it's a fairly 'new' tag (from the HTML5 specification afaik) you might want to to browser testing to make sure your target audience is fine with this solution.
(If not tell tell them to upgrade browser 'cause this tag works like a charm ;o) )

And finally a mini-fiddle to see it directly in action: http://jsfiddle.net/LnU9t/

Edit: Here is a plain jQuery solution which will also clear the input field if an escape keystroke is detected: http://jsfiddle.net/3GLwE/

Not very clean but it works :)

Dim arr As Integer() = {1, 2, 3}
Dim newItem As Integer = 4

arr = arr.Concat({newItem}).ToArray

You want a geocoding application. These are available either online or as an application backend.

• Online applications:

  • Google has a geocoding API

• Backend applications:

  • GeoStan

You need to add a return to the index.html file.

app.use(express.static(path.join(__dirname, 'build')));

app.get('*', function(req, res) {res.sendFile(path.join(__dirname + '/build/index.html')); });

Your using declaration is in game.cpp, not game.h where you actually declare string variables. You intended to put using namespace std; into the header, above the lines that use string, which would let those lines find the string type defined in the std namespace.

As others have pointed out, this is not good practice in headers -- everyone who includes that header will also involuntarily hit the using line and import std into their namespace; the right solution is to change those lines to use std::string instead

The code should be like given below

String selectSQL = "SELECT IFNULL(tbl.column, \"\") AS column FROM MySQL_table AS tbl";
Statement st = ...;
Result set rs = st.executeQuery(selectSQL);

You mean this?

<style type="text/css">
.bgimg {
    background-image: url('../images/divbg.png');
}
</style>

...

<div class="bgimg">
    div with background
</div>

Instead of putting the listview inside Scrollview, put the rest of the content between listview and the opening of the Scrollview as a separate view and set that view as the header of the listview. So you will finally end up only list view taking charge of Scroll.

This is a feature of C# 4.0, but was not possible without using function overload prior to that version.

My experience when working with large & complicated XML files is that sometimes neither Elements nor Descendants seem to work in retrieving a specific Element (and I still do not know why).

In such cases, I found that a much safer option is to manually search for the Element, as described by the following MSDN post:

https://social.msdn.microsoft.com/Forums/vstudio/en-US/3d457c3b-292c-49e1-9fd4-9b6a950f9010/how-to-get-tag-name-of-xml-by-using-xdocument?forum=csharpgeneral

In short, you can create a GetElement function:

private XElement GetElement(XDocument doc,string elementName)
{
    foreach (XNode node in doc.DescendantNodes())
    {
        if (node is XElement)
        {
            XElement element = (XElement)node;
            if (element.Name.LocalName.Equals(elementName))
                return element;
        }
    }
    return null;
}

Which you can then call like this:

XElement element = GetElement(doc,"Band");

Note that this will return null if no matching element is found.

Class Names. For test fixture names, I find that "Test" is quite common in the ubiquitous language of many domains. For example, in an engineering domain: StressTest, and in a cosmetics domain: SkinTest. Sorry to disagree with Kent, but using "Test" in my test fixtures (StressTestTest?) is confusing.

"Unit" is also used a lot in domains. E.g. MeasurementUnit. Is a class called MeasurementUnitTest a test of "Measurement" or "MeasurementUnit"?

Therefore I like to use the "Qa" prefix for all my test classes. E.g. QaSkinTest and QaMeasurementUnit. It is never confused with domain objects, and using a prefix rather than a suffix means that all the test fixtures live together visually (useful if you have fakes or other support classes in your test project)

Namespaces. I work in C# and I keep my test classes in the same namespace as the class they are testing. It is more convenient than having separate test namespaces. Of course, the test classes are in a different project.

Test method names. I like to name my methods WhenXXX_ExpectYYY. It makes the precondition clear, and helps with automated documentation (a la TestDox). This is similar to the advice on the Google testing blog, but with more separation of preconditions and expectations. For example:

WhenDivisorIsNonZero_ExpectDivisionResult
WhenDivisorIsZero_ExpectError
WhenInventoryIsBelowOrderQty_ExpectBackOrder
WhenInventoryIsAboveOrderQty_ExpectReducedInventory

This happened to me also. And I found the javaw.exe in C:\Windows\System32 got deleted after the windows update. Copied one more time and Eclipse started all fine.

Use LINQ Aggregate method to convert array of integers to a comma separated string

var intArray = new []{1,2,3,4};
string concatedString = intArray.Aggregate((a, b) =>Convert.ToString(a) + "," +Convert.ToString( b));
Response.Write(concatedString);

output will be

1,2,3,4

This is one of the solution you can use if you have not .net 4 installed.

The issue was that the file I was trying to import was so large that IntelliJ wouldn't run any CodeInsights on it.

Setting the idea.max.intellisense.filesize option to a higher value as per the instructions on this answer resolved my issue.

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

The common practice is to put scripts in a discrete folder, typically at the root of the site. So, if clock.js lived here:

/js/clock.js

then you could add this code to the top of any page in your site and it would just work:

<script src="/js/clock.js" type="text/javascript"></script>

Try:

adb shell pidof <myPackageName>

Standard output will be empty if the Application is not running. Otherwise, it will output the PID.

You can use the re module:

import re
re.sub(r'\D', '', '+123-456-7890')

This will replace all non-digits with ''.

Hardware

If a GPU device has, for example, 4 multiprocessing units, and they can run 768 threads each: then at a given moment no more than 4*768 threads will be really running in parallel (if you planned more threads, they will be waiting their turn).

Software

threads are organized in blocks. A block is executed by a multiprocessing unit. The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).

Obviously, if you need more than those 4*768 threads you need more than 4 blocks. Blocks may be also indexed 1D, 2D or 3D. There is a queue of blocks waiting to enter the GPU (because, in our example, the GPU has 4 multiprocessors and only 4 blocks are being executed simultaneously).

Now a simple case: processing a 512x512 image

Suppose we want one thread to process one pixel (i,j).

We can use blocks of 64 threads each. Then we need 512*512/64 = 4096 blocks (so to have 512x512 threads = 4096*64)

It's common to organize (to make indexing the image easier) the threads in 2D blocks having blockDim = 8 x 8 (the 64 threads per block). I prefer to call it threadsPerBlock.

dim3 threadsPerBlock(8, 8);  // 64 threads

and 2D gridDim = 64 x 64 blocks (the 4096 blocks needed). I prefer to call it numBlocks.

dim3 numBlocks(imageWidth/threadsPerBlock.x,  /* for instance 512/8 = 64*/
              imageHeight/threadsPerBlock.y); 

The kernel is launched like this:

myKernel <<<numBlocks,threadsPerBlock>>>( /* params for the kernel function */ );       

Finally: there will be something like "a queue of 4096 blocks", where a block is waiting to be assigned one of the multiprocessors of the GPU to get its 64 threads executed.

In the kernel the pixel (i,j) to be processed by a thread is calculated this way:

uint i = (blockIdx.x * blockDim.x) + threadIdx.x;
uint j = (blockIdx.y * blockDim.y) + threadIdx.y;

Note that Robert's answer is correct, and it works in sh as well. You can (portably) simplify it even further:

for i in "$@"

is equivalent to:

for i

I.e., you don't need anything!

Testing ($ is command prompt):

$ set a b "spaces here" d
$ for i; do echo "$i"; done
a
b
spaces here
d
$ for i in "$@"; do echo "$i"; done
a
b
spaces here
d

I first read about this in Unix Programming Environment by Kernighan and Pike.

In bash, help for documents this:

for NAME [in WORDS ... ;] do COMMANDS; done

If 'in WORDS ...;' is not present, then 'in "$@"' is assumed.

New, resurrected project site (Win7 compability and more!): http://sshwindows.sourceforge.net

1st January 2012

• OpenSSH for Windows 5.6p1-2 based release created!!
• Happy New Year all! Since COpSSH has started charging I've resurrected this project
• Updated all binaries to current releases
• Added several new supporting DLLs as required by all executables in package
• Renamed switch.exe to bash.exe to remove the need to modify and compile mkpasswd.exe each build
• Please note there is a very minor bug in this release, detailed in the docs. I'm working on fixing this, anyone who can code in C and can offer a bit of help it would be much appreciated

You can write your own extension method

public static class IntegerExtensions
{
    public static int ParseInt(this string value, int defaultValue = 0)
    {
        int parsedValue;
        if (int.TryParse(value, out parsedValue))
        {
            return parsedValue;
        }

        return defaultValue;
    }

    public static int? ParseNullableInt(this string value)
    {
        if (string.IsNullOrEmpty(value))
        {
            return null;
        }

        return value.ParseInt();
    }
}

And wherever in code just call

int myNumber = someString.ParseInt(); // Returns value or 0
int age = someString.ParseInt(18); // With default value 18
int? userId = someString.ParseNullableInt(); // Returns value or null

In this concrete case

int yourValue = TextBoxD1.Text.ParseInt();

Try downgrading to Virtual Box 4.2.18, if you are using 4.3.X.

I had a similar situation to yours.

I was using Genymotion 1.3.0 on Win7, with latest Virtual Box 4.3.2. Genymotion broke down after a computer shutdown, and never worked again.

I kinda stumbled onto this solution. After downgrading, Genymotion survived one shutdown now.

P.S. Changing network/resources settings in Virtual Box didn't help me, so I'm putting this up and hope it helps.

You could use the built-in exec statement, eg.:

exec("try: \n \t if sam[0] != 'harry': \n \t\t print('hello',  sam) \nexcept: pass")

Where \n is a newline and \t is used as indentation (a tab).
Also, you should count the spaces you use, so your indentation matches exactly.

However, as all the other answers already said, this is of course only to be used when you really have to put it on one line.

exec is quite a dangerous statement (especially when building a webapp) since it allows execution of arbitrary Python code.

it doenst work for me but it prints the correct element to the console

this is the code:

function click(x, y)
{
    var ev = new MouseEvent('click', {
        'view': window,
        'bubbles': true,
        'cancelable': true,
        'screenX': x,
        'screenY': y
    });

    var el = document.elementFromPoint(x, y);
    console.log(el); //print element to console
    el.dispatchEvent(ev);
}
click(400, 400);

Not a perfect solution, but this CSS might help. The zoom is what makes this code work, and the factor should theoretically be infinite to work ideally for small images - but 2, 4, or 8 works fine in most cases.

#myImage {
    zoom: 2;  //increase if you have very small images

    display: block;

Well i know i am late to the party, but logging my answer here , incase, someone is facing similar issue as mine. I have faced this issue many times. 90% it gets solved by these two steps

project > properties > Build > Platform target > x64 (x32)

Test -> Test Settings > Default Processor Architecture > X64 (x32)

However i found one more common cause. The Solution files often change developer systems and they start pointing to wrong MSTest.TestAdapter. Especially if you are using custom path of nuget packages. I solved this issue by

1. Opening the .csproj file in notepad.

2. Manually correcting reference to MSTest.TestAdapter in import instructions like this.

As of 2015, it now just works.

<input type="file">

This will ask user for the upload of any file. On iOS 8.x this can be a camera video, camera photo, or a photo/video from Photo Library.

<input type="file" accept="image/*">

This is as above, but limits the uploads to photos only from camera or library, no videos.

This should work:

if (variable === "") {

}

package name with 0 may cause problem for sharedPreference.

(OK) con = createPackageContext("com.example.android.sf1", 0);

(Problem but no error)

con = createPackageContext("com.example.android.sf01", 0);

Create an integer random between e.g. 1-11 and multiply it by 5. Simple math.

import random
for x in range(20):
  print random.randint(1,11)*5,
print

produces e.g.

5 40 50 55 5 15 40 45 15 20 25 40 15 50 25 40 20 15 50 10

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

File FileOne.js:

module.exports = { ClientIDUnsplash : 'SuperSecretKey' };

File FileTwo.js:

var { ClientIDUnsplash } = require('./FileOne');

This example works best for React.

select * from left table where key field not in (select key field from right table)

contents = open(filename)

This gives you generator so you must save somewhere the values though, or

contents = [line for line in open(filename)]

This does the saving to list explicit close is not then possible (at least with my knowledge of Python).

Or :

    var _ = require('underscore')._;

This is what I managed to do so far. I guess this is kind of what you're trying to pull out. The only thing is that I can still not manage to assign the proper height to the container DIV.

JSFIDDLE

The HTML:

<div id="container">
    <div id="header">HEADER</div>
    <div id="fixeddiv-top">FIXED DIV (TOP)</div>
    <div id="content-container">
        <div id="content">CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT<br>CONTENT</div>
    </div>
    <div id="fixeddiv-bottom">FIXED DIV (BOTTOM)</div>
</div>

And the CSS:

html {
    height:100%;
}
body {
    height:100%;
    margin:0;
    padding:0;
}
#container {
    width:600px;
    height:50%;
    text-align:center;
    display:block;
    position:relative;
}
#header {
    background:#069;
    text-align:center;
    width:100%;
    height:80px;
}
#fixeddiv-top {
    background:#AAA;
    text-align:center;
    width:100%;
    height:20px;
}
#content-container {
    height:100%;
}
#content {
    text-align:center;
    height:100%;
    background:#F00;
    margin:0 auto;
    overflow:auto;
}
#fixeddiv-bottom {
    background:#AAA;
    text-align:center;
    width:100%;
    height:20px;
}

There is some performance issue regarding to marshaling and unmarshaling. Parcelable is twice faster than Serializable.

Please go through the following link:

var Test = React.createClass({
     add: function(event){
         if(event.key === 'Enter'){
            alert('Adding....');
         }
     },
     render: function(){
        return(
           <div>
            <input type="text" id="one" onKeyPress={(event) => this.add(event)}/>    
          </div>
        );
     }
});

Attach with jvisualvm from Sun Java 6 JDK. Startup flags are listed.

well, this using lodash or vanilla javascript it depends on the situation.

but for just return the array that contains the duplicates it can be achieved by the following, offcourse it was taken from @1983

var result = result1.filter(function (o1) {
    return result2.some(function (o2) {
        return o1.id === o2.id; // return the ones with equal id
   });
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));

For CentOS: When installing php-gd you need to specify the version. I fixed it by running: sudo yum install php55-gd

In bootstrap 4 it is much easier to have a border on the fieldset that blends with the legend. You don't need custom css to achieve it, it can be done like this:

<fieldset class="border p-2">
   <legend  class="w-auto">Your Legend</legend>
</fieldset>

which looks like this:

You simply cannot get PowerShell to ommit those pesky newlines. There is no script or cmdlet that does this.

Of course Write-Host is absolute nonsense because you can't redirect/pipe from it! You simply have to write your own:

using System;

namespace WriteToStdout
{
    class Program
    {
        static void Main(string[] args)
        {
            if (args != null)
            {
                Console.Write(string.Join(" ", args));
            }
        }
    }
}

E.g.

PS C:\> writetostdout finally I can write to stdout like echo -n
finally I can write to stdout like echo -nPS C:\>

Here is another way to loop through XML elements using JDOM.

        List<Element> nodeNodes = inputNode.getChildren();
        if (nodeNodes != null) {
            for (Element nodeNode : nodeNodes) {
                List<Element> elements = nodeNode.getChildren(elementName);
                if (elements != null) {
                    elements.size();
                    nodeNodes.removeAll(elements);
                }
            }

Numpy arrays have an astype method. Just do y.astype(int).

Note that it might not even be necessary to do this, depending on what you're using the array for. Bool will be autopromoted to int in many cases, so you can add it to int arrays without having to explicitly convert it:

>>> x
array([ True, False,  True], dtype=bool)
>>> x + [1, 2, 3]
array([2, 2, 4])

Dir.foreach("/home/mydir") do |fname|
  puts fname
end

There's no built-in function for this.

Function SheetExists(SheetName As String, Optional wb As Excel.Workbook)
   Dim s As Excel.Worksheet
   If wb Is Nothing Then Set wb = ThisWorkbook
   On Error Resume Next
   Set s = wb.Sheets(SheetName)
   On Error GoTo 0
   SheetExists = Not s Is Nothing
End Function

A different approach.
On the figure() call specify properties or modify the figure handle properties after h = figure().

This creates a full screen figure based on normalized units.
figure('units','normalized','outerposition',[0 0 1 1])

The units property can be adjusted to inches, centimeters, pixels, etc.

See figure documentation.
