I believe in your case something like

sort -t@ -k1.1,1.4 -k1.5,1.7 ... <inputfile

will work better. @ is the field separator, make sure it is a character that appears nowhere. then your input is considered as consisting of one column.

Edit: apparently clintp already gave a similar answer, sorry. As he points out, the flags 'n' and 'r' can be added to every -k.... option.

Im not a java developer but was using a java app to test a RESTful API. In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.

• CA.crt
• UTNAddTrustServer_CA.crt
• AddTrustExternalCARoot.crt

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

Specification

In the SVG specification version 1.1 the rendering order is based on the document order:

first element -> "painted" first

Reference to the SVG 1.1. Specification

3.3 Rendering Order

Elements in an SVG document fragment have an implicit drawing order, with the first elements in the SVG document fragment getting "painted" first. Subsequent elements are painted on top of previously painted elements.

Solution (cleaner-faster)

You should put the green circle as the latest object to be drawn. So swap the two elements.

<svg xmlns="http://www.w3.org/2000/svg" viewBox="30 70 160 120"> _x000D_
   <!-- First draw the orange circle -->_x000D_
   <circle fill="orange" cx="100" cy="95" r="20"/> _x000D_
_x000D_
   <!-- Then draw the green circle over the current canvas -->_x000D_
   <circle fill="green" cx="100" cy="105" r="20"/> _x000D_
</svg>

Here the fork of your jsFiddle.

Solution (alternative)

The tag use with the attribute xlink:href and as value the id of the element. Keep in mind that might not be the best solution even if the result seems fine. Having a bit of time, here the link of the specification SVG 1.1 "use" Element.

Purpose:

To avoid requiring authors to modify the referenced document to add an ID to the root element.

<svg xmlns="http://www.w3.org/2000/svg" viewBox="30 70 160 120">_x000D_
    <!-- First draw the green circle -->_x000D_
    <circle id="one" fill="green" cx="100" cy="105" r="20" />_x000D_
    _x000D_
    <!-- Then draw the orange circle over the current canvas -->_x000D_
    <circle id="two" fill="orange" cx="100" cy="95" r="20" />_x000D_
    _x000D_
    <!-- Finally draw again the green circle over the current canvas -->_x000D_
    <use xlink:href="#one"/>_x000D_
</svg>

Notes on SVG 2

SVG 2 Specification is the next major release and still supports the above features.

3.4. Rendering order

Elements in SVG are positioned in three dimensions. In addition to their position on the x and y axis of the SVG viewport, SVG elements are also positioned on the z axis. The position on the z-axis defines the order that they are painted.

Along the z axis, elements are grouped into stacking contexts.

3.4.1. Establishing a stacking context in SVG

...

Stacking contexts are conceptual tools used to describe the order in which elements must be painted one on top of the other when the document is rendered, ...

In short, it lets you assign values to a variable in an outer (but non-global) scope. See PEP 3104 for all the gory details.

As the others say, there is a MessageBox in the WPF namespace (System.Windows).

The problem is that it is the same old messagebox with OK, Cancel, etc. Windows Vista and Windows 7 have moved on to use Task Dialogs instead.

Unfortunately there is no easy standard interface for task dialogs. I use an implementation from CodeProject KB.

Today, in Office 365, Excel has so called 'array functions'. The filter function does exactly what you want. No need to use CTRL+SHIFT+ENTER anymore, a simple enter will suffice.

In Office 365, your problem would be simply solved by using:

=VLOOKUP(A3, FILTER(A2:C6, B2:B6="B"), 3, FALSE)

must separate this code to work well, or it well pause and play in one click !

 $('video').click(function(){this.played ? this.pause() ;});
  $('video').click(function(){this.paused ? this.play() ;});

Yahoo! This is really possible. I found it.

For Bottom Border:

div {box-shadow: 0px -3px 0px red inset; }

For Top Border:

div {box-shadow: 0px 3px 0px red inset; }

Actually the ng-disabled directive works with the " || " logical operator for me. The " && " evaluate only one condition.

PHP's mail() function does not have support for SMTP. You're going to need to use something like the PEAR Mail package.

Here is a sample SMTP mail script:

<?php
require_once("Mail.php");

$from = "Your Name <[email protected]>";
$to = "Their Name <[email protected]>";
$subject = "Subject";
$body = "Lorem ipsum dolor sit amet, consectetur adipiscing elit...";

$host = "mailserver.blahblah.com";
$username = "smtp_username";
$password = "smtp_password";

$headers = array('From' => $from, 'To' => $to, 'Subject' => $subject);

$smtp = Mail::factory('smtp', array ('host' => $host,
                                     'auth' => true,
                                     'username' => $username,
                                     'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if ( PEAR::isError($mail) ) {
    echo("<p>Error sending mail:<br/>" . $mail->getMessage() . "</p>");
} else {
    echo("<p>Message sent.</p>");
}
?>

Thx Burhan Khalid, I overlooked your "You need to be root" quote, but found the way when you are not the root here.

At point 7 you need to use:

sudo env ORACLE_HOME=$ORACLE_HOME python setup.py install 

Or

sudo env ORACLE_HOME=/path/to/instantclient python setup.py install

Also, be sure, that two-factor authentication is off, otherwise use personal access tokens

innerHTML sets the text (including html elements) inside an element. Normally we use it for elements like div, span etc to insert other html elements inside it.

For your case you want to set the value of an input element. So you should use the value attribute.

Change innerHTML to value

document.getElementById('add').value = sum;

Use the display property

a{
    display: block;
}

This will make the link to display in new line

If you want to remove list styling, use

li{
    list-style: none;
}

In some cases where tools like curl, telnet, nc o nmap are unavailable you still have a chance with wget

if [[ $(wget -q -t 1 --spider --dns-timeout 3 --connect-timeout 10  host:port; echo $?) -eq 0 ]]; then echo "OK"; else echo "FAIL"; fi

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

I had multiple versions of the gcc compiler installed and needed to use a more recent version than the default installation. Since I am not a system administrator for our Linux systems, I cannot just change /usr/lib or many of the other suggestions above. I was encountering this problem and eventually tracked it down to setting my path to the 32-bit library directory instead of the 64-bit library (lib64) directory. Since the libraries in the 32-bit directory were incompatible, the system defaulted to the older version which was out of date.

Using -L to the path I was referencing gave warnings about "skipping incompatible libstdc++.so when searching for -lstdc++". This was the hint that helped me finally resolve the problem.

You can change the level to OFF which should get rid of all logging. According to the log4j website, valid levels in order of importance are TRACE, DEBUG, INFO, WARN, ERROR, FATAL. There is one undocumented level called OFF which is a higher level than FATAL, and turns off all logging.

You can also create an extra root logger to log nothing (level OFF), so that you can switch root loggers easily. Here's a post to get you started on that.

You might also want to read the Log4J FAQ, because I think turning off all logging may not help. It will certainly not speed up your app that much, because logging code is executed anyway, up to the point where log4j decides that it doesn't need to log this entry.

Collation can be simply thought of as sort order.

In English (and it's strange cousin, American), collation may be a pretty simple matter consisting of ordering by the ASCII code.

Once you get into those strange European languages with all their accents and other features, collation changes. For example, though the different accented forms of a may exist at disparate code points, they may all need to be sorted as if they were the same letter.

I know that is late to answer but could be useful for someone else You can use sub-query and convert the null to 0

SELECT *
FROM (SELECT CASE WHEN id_field IS NULL 
                THEN 0 
                ELSE id_field 
            END AS id_field
      FROM tbl_name) AS tbl
WHERE tbl.id_field IN ('value1', 'value2', 'value3', 0)

It usually happens when the certificate does not match with the host name.

The solution would be to contact the host and ask it to fix its certificate.
Otherwise you can turn off cURL's verification of the certificate, use the -k (or --insecure) option.
Please note that as the option said, it is insecure. You shouldn't use this option because it allows man-in-the-middle attacks and defeats the purpose of HTTPS.

If I understand correctly then it would be easier if you gave your image a transparent background and set the background container's background-color property without having to use filters and so on.

http://www.ajaxblender.com/howto-convert-image-to-grayscale-using-javascript.html

Shows you how to use filters in IE. Maybe if you leverage something from that. Not very cross-browser compatible though. Another option might be to have two images and use them as background-images (rather than img tags), swap one out after another using the :hover pseudo selector.

Use debug_backtrace to get a backtrace of what functions and methods had been called and what files had been included that led to the point where debug_backtrace has been called.

This answer will demonstrate the difference between implementation, api, and compile on a project.

Let's say I have a project with three Gradle modules:

• app (an Android application)
• myandroidlibrary (an Android library)
• myjavalibrary (a Java library)

app has myandroidlibrary as dependencies. myandroidlibrary has myjavalibrary as dependencies.

myjavalibrary has a MySecret class

public class MySecret {

    public static String getSecret() {
        return "Money";
    }
}

myandroidlibrary has MyAndroidComponent class that manipulate value from MySecret class.

public class MyAndroidComponent {

    private static String component = MySecret.getSecret();

    public static String getComponent() {
        return "My component: " + component;
    }    
}

Lastly, app is only interested in the value from myandroidlibrary

TextView tvHelloWorld = findViewById(R.id.tv_hello_world);
tvHelloWorld.setText(MyAndroidComponent.getComponent());

Now, let's talk about dependencies...

app need to consume :myandroidlibrary, so in app build.gradle use implementation.

(Note: You can use api/compile too. But hold that thought for a moment.)

dependencies {
    implementation project(':myandroidlibrary')      
}

What do you think myandroidlibrary build.gradle should look like? Which scope we should use?

We have three options:

dependencies {
    // Option #1
    implementation project(':myjavalibrary') 
    // Option #2
    compile project(':myjavalibrary')      
    // Option #3
    api project(':myjavalibrary')           
}

What's the difference between them and what should I be using?

Compile or Api (option #2 or #3)

If you're using compile or api. Our Android Application now able to access myandroidcomponent dependency, which is a MySecret class.

TextView textView = findViewById(R.id.text_view);
textView.setText(MyAndroidComponent.getComponent());
// You can access MySecret
textView.setText(MySecret.getSecret());

Implementation (option #1)

If you're using implementation configuration, MySecret is not exposed.

TextView textView = findViewById(R.id.text_view);
textView.setText(MyAndroidComponent.getComponent());
// You can NOT access MySecret
textView.setText(MySecret.getSecret()); // Won't even compile

So, which configuration you should choose? That really depends on your requirement.

If you want to expose dependencies use api or compile.

If you don't want to expose dependencies (hiding your internal module) then use implementation.

Note:

This is just a gist of Gradle configurations, refer to Table 49.1. Java Library plugin - configurations used to declare dependencies for more detailed explanation.

Create a role add this role to users, and then you can grant execute to all the routines in one shot to this role.

CREATE ROLE <abc>
GRANT EXECUTE TO <abc>

EDIT
This works in SQL Server 2005, I'm not sure about backward compatibility of this feature, I'm sure anything later than 2005 should be fine.

The os.exec*() functions replace the current programm with the new one. When this programm ends so does your process. You probably want os.system().

You specify the escape character. Documentation here:
http://msdn.microsoft.com/en-us/library/ms179859.aspx

You can try the some thing like the below LINQ snippet.

string[] allLines = File.ReadAllLines(@"E:\Temp\data.csv");

    var query = from line in allLines
                let data = line.Split(',')
                select new
                {
                    Device = data[0],
                    SignalStrength = data[1],
                    Location = data[2], 
                    Time = data[3],
                    Age = Convert.ToInt16(data[4])
                };

UPDATE: Over a period of time, things evolved. As of now, I would prefer to use this library http://www.aspnetperformance.com/post/LINQ-to-CSV-library.aspx

As biziclop mentioned, some sort of metric space tree would probably be your best option. I have experience using kd-trees and quad trees to do these sorts of range queries and they're amazingly fast; they're also not that hard to write. I'd suggest looking into one of these structures, as they also let you answer other interesting questions like "what's the closest point in my data set to this other point?"

Encountered this issue in chrome. Resolved by cleaning up related cookies. Note that you don't have to cleanup ALL your cookies.

I did this.

class Circle
{
    constuctor(radius)
    {
        this.radius = radius;
    }
    static get PI()
    {
        return 3.14159;
    }
}

The value of PI is protected from being changed since it is a value being returned from a function. You can access it via Circle.PI. Any attempt to assign to it is simply dropped on the floor in a manner similar to an attempt to assign to a string character via [].

It is not safe to modify the sequence being iterated over in the loop (this can only happen for mutable sequence types, such as lists). If you need to modify the list you are iterating over (for example, to duplicate selected items) you must iterate over a copy.

In my case, I wanted to enable/disable the cursor when the edit is focused.

In your Activity:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN) {
        View v = getCurrentFocus();
        if (v instanceof EditText) {
            EditText edit = ((EditText) v);
            Rect outR = new Rect();
            edit.getGlobalVisibleRect(outR);
            Boolean isKeyboardOpen = !outR.contains((int)ev.getRawX(), (int)ev.getRawY());
            System.out.print("Is Keyboard? " + isKeyboardOpen);
            if (isKeyboardOpen) {
                System.out.print("Entro al IF");
                edit.clearFocus();
                InputMethodManager imm = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(edit.getWindowToken(), 0);
            }

            edit.setCursorVisible(!isKeyboardOpen);

        }
    }
    return super.dispatchTouchEvent(ev);
}

There is a plugin, flutter_launcher_name.

Write file pubspec.yaml:

dev_dependencies:
  flutter_launcher_name: "^0.0.1"

flutter_launcher_name:
  name: "yourNewAppLauncherName"

And run:

flutter pub get
flutter pub run flutter_launcher_name:main

You can get the same result as editing AndroidManifes.xml and Info.plist.

I dont think you can, Java uses type erasure when compiling so your code is compatible with applications and libraries that were created pre-generics.

From the Oracle Docs:

Type Erasure

Generics were introduced to the Java language to provide tighter type checks at compile time and to support generic programming. To implement generics, the Java compiler applies type erasure to:

Replace all type parameters in generic types with their bounds or Object if the type parameters are unbounded. The produced bytecode, therefore, contains only ordinary classes, interfaces, and methods. Insert type casts if necessary to preserve type safety. Generate bridge methods to preserve polymorphism in extended generic types. Type erasure ensures that no new classes are created for parameterized types; consequently, generics incur no runtime overhead.

http://docs.oracle.com/javase/tutorial/java/generics/erasure.html

Using the generified version of class Class allows you, among other things, to write things like

Class<? extends Collection> someCollectionClass = someMethod();

and then you can be sure that the Class object you receive extends Collection, and an instance of this class will be (at least) a Collection.

Yes, as long as the url you type into the browser www.someshopping.com and you aren't using url rewriting then

string currentURL = HttpContext.Current.Request.Url.Host;

will return www.someshopping.com

Note the difference between a local debugging environment and a production environment

Make a png image with same name (favicon.png) and change the name in these files:

index.html:

<link rel="icon" type="image/x-icon" href="favicon.png" />

angular-cli.json:

"assets": [
    "assets",
    "favicon.png" 
],

And you will never see the angular default icon again.

Size should be 32x32, if more than this it will not display.

NOTE: This will not work with Angular 9

For angular 9 you have to put favicon inside assets then give path like

<link rel="icon" type="image/x-icon" href="assets/favicon.png">

There are two issues here.

Firstly, you can't use the [] syntax like you may be able to in other languages. Square brackets only apply to arrays in Java, and so can only be used with integer indexes.

data.put is correct but that is a statement and so must exist in a method block. Only field declarations can exist at the class level. Here is an example where everything is within the local scope of a method:

public class Data {
     public static void main(String[] args) {
         Map<String, String> data = new HashMap<String, String>();
         data.put("John", "Taxi Driver");
         data.put("Mark", "Professional Killer");
     }
 }

If you want to initialize a map as a static field of a class then you can use Map.of, since Java 9:

public class Data {
    private static final Map<String, String> DATA = Map.of("John", "Taxi Driver");
}

Before Java 9, you can use a static initializer block to accomplish the same thing:

public class Data {
    private static final Map<String, String> DATA = new HashMap<>();

    static {
        DATA.put("John", "Taxi Driver");
    }
}

<img src='thumb.gif' onclick='this.src="full_size.gif"' />

Of course you can change the onclick event to load the image wherever you want.

Use port number 22 (for sftp) instead of 21 (normal ftp). Solved this problem for me.

In some cases String.length might return a value which is different from the actual number of characters visible on the screen (e.g. some emojis are encoded by 2 UTF-16 units):

MDN says: This property returns the number of code units in the string. UTF-16, the string format used by JavaScript, uses a single 16-bit code unit to represent the most common characters, but needs to use two code units for less commonly-used characters, so it's possible for the value returned by length to not match the actual number of characters in the string.

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }

  <?php
    if( $posted ) {
      if( $result )

      else
        echo "<script type='text/javascript'>alert('failed!')</script>";

  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

Here is an example straight from PHP.net

$a = array(
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => 17
);

foreach ($a as $k => $v) {
    echo "\$a[$k] => $v.\n";
}

in the foreach you can do a comparison of each key to something that you are looking for

In response to @A.M.K's question about how to do transitions without jQuery. A very simple example I threw together. If I had time to think this through some more, I might be able to eliminate the JavaScript code altogether:

<style>
    body {
        background-color: red;
        transition: background-color 2s ease-in;
    }
</style>

<script>
    window.onload = function() {
        document.body.style.backgroundColor = '#00f';
    }
</script>

<body>
    <p>test</p>
</body>

On the client side you can add and remove websites to be displayed in Compatibility View from Compatibility View Settings window of IE:

Tools-> Compatibility View Settings

The static keyword, when applied to a class, tells the compiler to create a single instance of that class. It is not then possible to 'new' one or more instance of the class. All methods in a static class must themselves be declared static.

It is possible, And often desirable, to have static methods of a non-static class. For example a factory method when creates an instance of another class is often declared static as this means that a particular instance of the class containing the factor method is not required.

For a good explanation of how, when and where see MSDN

Not only can you, but you have to make a special effort not to if you don't want to. :-)

When the browser encounters a classic script tag when parsing the HTML, it stops parsing and hands over to the JavaScript interpreter, which runs the script. The parser doesn't continue until the script execution is complete (because the script might do document.write calls to output markup that the parser should handle).

That's the default behavior, but you have a few options for delaying script execution:

1. Use JavaScript modules. A type="module" script is deferred until the HTML has been fully parsed and the initial DOM created. This isn't the primary reason to use modules, but it's one of the reasons:

   <script type="module" src="./my-code.js"></script>
   <!-- Or -->
   <script type="module">
   // Your code here
   </script>
   

   The code will be fetched (if it's separate) and parsed in parallel with the HTML parsing, but won't be run until the HTML parsing is done. (If your module code is inline rather than in its own file, it is also deferred until HTML parsing is complete.)

   This wasn't available when I first wrote this answer in 2010, but here in 2020, all major modern browsers support modules natively, and if you need to support older browsers, you can use bundlers like Webpack and Rollup.js.

2. Use the defer attribute on a classic script tag:

   <script defer src="./my-code.js"></script>
   

   As with the module, the code in my-code.js will be fetched and parsed in parallel with the HTML parsing, but won't be run until the HTML parsing is done. But, defer doesn't work with inline script content, only with external files referenced via src.

3. I don't think it's what you want, but you can use the async attribute to tell the browser to fetch the JavaScript code in parallel with the HTML parsing, but then run it as soon as possible, even if the HTML parsing isn't complete. You can put it on a type="module" tag, or use it instead of defer on a classic script tag.

4. Put the script tag at the end of the document, just prior to the closing </body> tag:

   <!doctype html>
   <html>
   <!-- ... -->
   <body>
   <!-- The document's HTML goes here -->
   <script type="module" src="./my-code.js"></script><!-- Or inline script -->
   </body>
   </html>
   

   That way, even though the code is run as soon as its encountered, all of the elements defined by the HTML above it exist and are ready to be used.

   It used to be that this caused an additional delay on some browsers because they wouldn't start fetching the code until the script tag was encountered, but modern browsers scan ahead and start prefetching. Still, this is very much the third choice at this point, both modules and defer are better options.

The spec has a useful diagram showing a raw script tag, defer, async, type="module", and type="module" async and the timing of when the JavaScript code is fetched and run:

Here's an example of the default behavior, a raw script tag:

.found {_x000D_
    color: green;_x000D_
}

<p>Paragraph 1</p>_x000D_
<script>_x000D_
    if (typeof NodeList !== "undefined" && !NodeList.prototype.forEach) {_x000D_
        NodeList.prototype.forEach = Array.prototype.forEach;_x000D_
    }_x000D_
    document.querySelectorAll("p").forEach(p => {_x000D_
        p.classList.add("found");_x000D_
    });_x000D_
</script>_x000D_
<p>Paragraph 2</p>

(See my answer here for details around that NodeList code.)

When you run that, you see "Paragraph 1" in green but "Paragraph 2" is black, because the script ran synchronously with the HTML parsing, and so it only found the first paragraph, not the second.

In contrast, here's a type="module" script:

.found {_x000D_
    color: green;_x000D_
}

<p>Paragraph 1</p>_x000D_
<script type="module">_x000D_
    document.querySelectorAll("p").forEach(p => {_x000D_
        p.classList.add("found");_x000D_
    });_x000D_
</script>_x000D_
<p>Paragraph 2</p>

Notice how they're both green now; the code didn't run until HTML parsing was complete. That would also be true with a defer script with external content (but not inline content).

(There was no need for the NodeList check there because any modern browser supporting modules already has forEach on NodeList.)

In this modern world, there's no real value to the DOMContentLoaded event of the "ready" feature that PrototypeJS, jQuery, ExtJS, Dojo, and most others provided back in the day (and still provide); just use modules or defer. Even back in the day, there wasn't much reason for using them (and they were often used incorrectly, holding up page presentation while the entire jQuery library was loaded because the script was in the head instead of after the document), something some developers at Google flagged up early on. This was also part of the reason for the YUI recommendation to put scripts at the end of the body, again back in the day.

I experienced this issue and I preferred to free up the port .80 and my XAMPP/Apache restarted again. This is how I made the port .80 free. First: -Open a command prompt and type this :

netstat -aon | findstr :80

You'll get this display:

Then type this command:

tasklist /fi "pid eq 4"

You'll get the name of the process using the is displayed. Now, press: Win+R services.msc in the invite, then press Ok. Now you can start stopping all services which can use the port .80.

Find some of them here: W3SVC,WAS,SSRS,PeerDistSvc,NcbService.

It means "don't echo the command to standard output".

Rather strangely,

echo off

will send echo off to the output! So,

@echo off

sets this automatic echo behaviour off - and stops it for all future commands, too.

Something like this:

setUsers = function (data) {
    for (k in data) {
        user[k] = data[k];
    }
}

You can do something like that in pure html using an <object> tag:
<div><object data="file.txt"></object></div>

This method has some limitations though, like, it won't fit size of the block to the content - you have to specify width and height manually. And styles won't be applied to the text.

function range(start, end) {
    var foo = [];
    for (var i = start; i <= end; i++) {
        foo.push(i);
    }
    return foo;
}

Then called by

var foo = range(1, 5);

There is no built-in way to do this in Javascript, but it's a perfectly valid utility function to create if you need to do it more than once.

Edit: In my opinion, the following is a better range function. Maybe just because I'm biased by LINQ, but I think it's more useful in more cases. Your mileage may vary.

function range(start, count) {
    if(arguments.length == 1) {
        count = start;
        start = 0;
    }

    var foo = [];
    for (var i = 0; i < count; i++) {
        foo.push(start + i);
    }
    return foo;
}

I believe you are looking for the query functions, isBefore, isSame, and isAfter.

But it's a bit difficult to tell exactly what you're attempting. Perhaps you are just looking to get the difference between the input time and the current time? If so, consider the difference function, diff. For example:

moment().diff(date_time, 'minutes')

A few other things:

• There's an error in the first line:

    var date_time = 2013-03-24 + 'T' + 10:15:20:12 + 'Z'
  

  That's not going to work. I think you meant:

    var date_time = '2013-03-24' + 'T' + '10:15:20:12' + 'Z';
  

  Of course, you might as well:

    var date_time = '2013-03-24T10:15:20:12Z';
  

• You're using: .tz('UTC') incorrectly. .tz belongs to moment-timezone. You don't need to use that unless you're working with other time zones, like America/Los_Angeles.

  If you want to parse a value as UTC, then use:

    moment.utc(theStringToParse)
  

  Or, if you want to parse a local value and convert it to UTC, then use:

    moment(theStringToParse).utc()
  

  Or perhaps you don't need it at all. Just because the input value is in UTC, doesn't mean you have to work in UTC throughout your function.

• You seem to be getting the "now" instance by moment(new Date()). You can instead just use moment().

Updated

Based on your edit, I think you can just do this:

var date_time = req.body.date + 'T' + req.body.time + 'Z';
var isafter = moment(date_time).isAfter('2014-03-24T01:14:00Z');

Or, if you would like to ensure that your fields are validated to be in the correct format:

var m = moment.utc(req.body.date + ' ' + req.body.time, "YYYY-MM-DD  HH:mm:ss");
var isvalid = m.isValid();
var isafter = m.isAfter('2014-03-24T01:14:00Z');

Just to give my 2 cents to this answer, there have been some other clients born since the raise of Postman that worth mentioning here:

• Insomnia: with both desktop app and chrome plugin
• Hoppscotch: previously known as Postwoman, and with a chrome plugin available as well. You can also make it work locally with docker if you want to get funny
• Paw: if you are on Mac
• Advanced Rest Client: already mentioned as a chrome plugin, but worth pointing out that it also has a desktop app
• soapUI: written in java and with lots of testing functionality
• Boomerang: yet another way to test APIs. It comes with SOAP integration and it also has a chrome plugin available

According to 'Getting Started With LLVM Core Libraries' book (c):

In fact, the name LLVM might refer to any of the following:

• The LLVM project/infrastructure: This is an umbrella for several projects that, together, form a complete compiler: frontends, backends, optimizers, assemblers, linkers, libc++, compiler-rt, and a JIT engine. The word "LLVM" has this meaning, for example, in the following sentence: "LLVM is comprised of several projects".

• An LLVM-based compiler: This is a compiler built partially or completely with the LLVM infrastructure. For example, a compiler might use LLVM for the frontend and backend but use GCC and GNU system libraries to perform the final link. LLVM has this meaning in the following sentence, for example: "I used LLVM to compile C programs to a MIPS platform".

• LLVM libraries: This is the reusable code portion of the LLVM infrastructure. For example, LLVM has this meaning in the sentence: "My project uses LLVM to generate code through its Just-in-Time compilation framework".

• LLVM core: The optimizations that happen at the intermediate language level and the backend algorithms form the LLVM core where the project started. LLVM has this meaning in the following sentence: "LLVM and Clang are two different projects".

• The LLVM IR: This is the LLVM compiler intermediate representation. LLVM has this meaning when used in sentences such as "I built a frontend that translates my own language to LLVM".

Math.floor(n)

where n is a double. This'll actually return a double, it seems, so make sure that you typecast it after.

The easiest way to solve this in pure HTML is to use the <base href="…"> element like so:

<base href="http://localhost/mywebsite/" />

Then all of the URLs in your HTML can just be this:

<a href="images/example.png">Link To Image</a>

Just change the <base href="…"> to match your server. The rest of the HTML paths will just fall in line and will be appended to that.

transferring file from local to remote host

scp -i (path of your key) (path for your file to be transferred) (username@ip):(path where file to be copied)

e.g scp -i aws.pem /home/user1/Desktop/testFile   ec2-user@someipAddress:/home/ec2-user/

P.S. - ec2-user@someipAddress of this ip address should have access to the destination folder in my case /home/ec2-user/

Just use Val():

currentLoad = Int(Val([f4]))

Now currentLoad has a integer value, zero if [f4] is not numeric.

Actually using 100% will not make the image bigger if the image is smaller than the div size you specified. You need to set one of the dimensions, height or width in order to have all images fill the space. In my experience it's better to have the height set so each row is the same size, then all items wrap to next line properly. This will produce an output similar to fotolia.com (stock image website)

with css:

parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 42px;
}

without:

<div style="height:42px;width:42px">
    <img style="height:42px" src="http://someimage.jpg">
</div>

Using javascript seems to be unnecessary if you choose CSS3.

By using :before selector, you can do this in two lines of CSS. (no script involved).

Another advantage of this approach is that it does not rely on <label> tag and works even it is missing.

Note: in browsers without CSS3 support, checkboxes will look normal. (backward compatible).

input[type=checkbox]:before { content:""; display:inline-block; width:12px; height:12px; background:red; }
input[type=checkbox]:checked:before { background:green; }?

1. Temp table: A Temp table is easy to create and back up data.

   Table variable: But the table variable involves the effort when we usually create the normal tables.

2. Temp table: Temp table result can be used by multiple users.

   Table variable: But the table variable can be used by the current user only. 

3. Temp table: Temp table will be stored in the tempdb. It will make network traffic. When we have large data in the temp table then it has to work across the database. A Performance issue will exist.

   Table variable: But a table variable will store in the physical memory for some of the data, then later when the size increases it will be moved to the tempdb.

4. Temp table: Temp table can do all the DDL operations. It allows creating the indexes, dropping, altering, etc..,

   Table variable: Whereas table variable won't allow doing the DDL operations. But the table variable allows us to create the clustered index only.

5. Temp table: Temp table can be used for the current session or global. So that a multiple user session can utilize the results in the table.

   Table variable: But the table variable can be used up to that program. (Stored procedure)

6. Temp table: Temp variable cannot use the transactions. When we do the DML operations with the temp table then it can be rollback or commit the transactions.

   Table variable: But we cannot do it for table variable.

7. Temp table: Functions cannot use the temp variable. More over we cannot do the DML operation in the functions .

   Table variable: But the function allows us to use the table variable. But using the table variable we can do that.

8. Temp table: The stored procedure will do the recompilation (can't use same execution plan) when we use the temp variable for every sub sequent calls.

   Table variable: Whereas the table variable won't do like that.

Yes, it's possible to use inline if-expressions:

{{ 'Update' if files else 'Continue' }}

It is better to use .Value2() instead of .Value(). This is faster and gives the exact value in the cell. For certain type of data, truncation can be observed when .Value() is used.

you can use:

define("PATH_ROOT", dirname(__FILE__));
include_once PATH_ROOT . "/PoliticalForum/headerSite.php";

This is a nice way to do it:

Double d = 0.5;
float f = d.floatValue();

if you have d as a primitive type just add one line:

double d = 0.5;
Double D = Double.valueOf(d);
float f = D.floatValue();

Can use it in the way like this:

//! Define:
#define F_NUM 3
int (*pFunctions[F_NUM])(void * arg);

//! Initialise:
int someFunction(void * arg) {
    int a= *((int*)arg);
    return a*a;
}

pFunctions[0]= someFunction;

//! Use:
int someMethod(int idx, void * arg, int * result) {
    int done= 0;
    if (idx < F_NUM && pFunctions[idx] != NULL) {
        *result= pFunctions[idx](arg);
        done= 1;
    }
    return done;
}

int x= 2;
int z= 0;
someMethod(0, (void*)&x, &z);
assert(z == 4);

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;

I apologize for promoting myself, but I have a jQuery plugin to launch native apps from web links https://github.com/eusonlito/jquery.applink

You can use it easy:

<script>
$('a[data-applink]').applink();
</script>

<a href="https://facebook.com/me" data-applink="fb://profile">My Facebook Profile</a>

You can also take a look on library Seismic

public class Demo extends Activity implements ShakeDetector.Listener {
  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SensorManager sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    ShakeDetector sd = new ShakeDetector(this);
    sd.start(sensorManager);

    TextView tv = new TextView(this);
    tv.setGravity(CENTER);
    tv.setText("Shake me, bro!");
    setContentView(tv, new LayoutParams(MATCH_PARENT, MATCH_PARENT));
  }

  @Override public void hearShake() {
    Toast.makeText(this, "Don't shake me, bro!", Toast.LENGTH_SHORT).show();
  }
}

When a and b are 1-dimensional sequences, numpy.cov(a,b)[0][1] is equivalent to your cov(a,b).

The 2x2 array returned by np.cov(a,b) has elements equal to

cov(a,a)  cov(a,b)

cov(a,b)  cov(b,b)

(where, again, cov is the function you defined above.)

Assume you want to install package MySQL-python on Windows, maybe try pip install command with --global-option. See the example command below:

pip install MySQL-python ^
 --force-reinstall --no-cache-dir ^
 --global-option=build_ext ^
 --global-option="-IC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\include" ^
 --global-option="-LC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\lib\opt" ^
 --verbose

For this example, I fully installed 64-bit version of MySQL Connector C in customized location of C:\my\install\MySQL-x64\MySQL Connector C 6.0.2\.

By the way, I noticed that pip install MySQL-python by default always looks into directory C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2\include, even if you're using 64-bit and/or have installed the driver at a different location. I tested on Python-2.7, and I guess this is a bug of either Python or MySQL-python.

Hope the above might be of some help.

I guess there is no white list in whatsapp, as I found a solution that worked for me. Do as follows. insert 3 meta tags:

<meta property="og:image" content="http://yourimage_with_complete_URL.png"/>  
<meta property="og:title" content="Your Title"/>  
<meta property="og:description" content="Your description."/>  

Your image must be in .png format and 600x600px dimension and must be named 'logo-yoursite.png' (once it worked for me JUST LIKE THAT)

Dont forget to insert the link to whatsapp in your website:

<a href='whatsapp://send?text=Text to send withe message: http://www.yoursite.com'>whatsApp</a>

Do this and you'll be well done!

            zippy.zipDir("folderName","test.zip");
        } catch(IOException e2) {

Changing the current directory is not the way to deal with finding modules in Python.

Rather, see the docs for The Module Search Path for how Python finds which module to import.

Here is a relevant bit from Standard Modules section:

The variable sys.path is a list of strings that determines the interpreter’s search path for modules. It is initialized to a default path taken from the environment variable PYTHONPATH, or from a built-in default if PYTHONPATH is not set. You can modify it using standard list operations:

>>> import sys
>>> sys.path.append('/ufs/guido/lib/python')

In answer your original question about getting and setting the current directory:

>>> help(os.getcwd)

getcwd(...)
    getcwd() -> path

    Return a string representing the current working directory.

>>> help(os.chdir)

chdir(...)
    chdir(path)

    Change the current working directory to the specified path.

If your business class is directly used by your UI is preferrable to use IDataErrorInfo because it put logic closer to their owner.

If your business class is a stub class created by a reference to an WCF/XmlWeb service then you can not/must not use IDataErrorInfo nor throw Exception for use with ExceptionValidationRule. Instead you can:

• Use custom ValidationRule.
• Define a partial class in your WPF UI project and implements IDataErrorInfo.

I handle it in the following way:

Python Code :

    from flask import Flask, render_template, request
    
    
    app = Flask(__name__)
    
    
    @app.route("/", methods=['GET', 'POST'])
    def index():
        print(request.method)
        if request.method == 'POST':
            if request.form.get('Encrypt') == 'Encrypt':
                # pass
                print("Encrypted")
            elif  request.form.get('Decrypt') == 'Decrypt':
                # pass # do something else
                print("Decrypted")
            else:
                # pass # unknown
                return render_template("index.html")
        elif request.method == 'GET':
            # return render_template("index.html")
            print("No Post Back Call")
        return render_template("index.html")
    
    
    if __name__ == '__main__':
        app.run()

A workaround is to:

write a counter in a firebase doc, which you increment within a transaction everytime you create a new entry

You store the count in a field of your new entry (i.e: position: 4).

Then you create an index on that field (position DESC).

You can do a skip+limit with a query.Where("position", "<" x).OrderBy("position", DESC)

Hope this helps!

It should work with:

.modal:before{
   opacity:0.001 !important;
}

I fixed this by simply restarting Visual Studio - I had just run dotnet tool install xxx in a console window and VS hadn't yet picked up the new environment variables and/or path settings that were changed, so a quick restart fixed the issue.

Here's an example of how to create a ColorList programmatically in Kotlin:

val colorList = ColorStateList(
        arrayOf(
                intArrayOf(-android.R.attr.state_enabled),  // Disabled
                intArrayOf(android.R.attr.state_enabled)    // Enabled
        ),
        intArrayOf(
                Color.BLACK,     // The color for the Disabled state
                Color.RED        // The color for the Enabled state
        )
)

if you are building a maven project through a command console, make sure the following is at the end of the command:

eclipse:eclipse -Dwtpversion=2.0

There are many answers which explain more detailed on the differences, but here is my very brief explanation.

One important difference is that VMs use a separate kernel to run the OS. That's the reason it is heavy and takes time to boot, consuming more system resources.

In Docker, the containers share the kernel with the host; hence it is lightweight and can start and stop quickly.

In Virtualization, the resources are allocated in the beginning of set up and hence the resources are not fully utilized when the virtual machine is idle during many of the times. In Docker, the containers are not allocated with fixed amount of hardware resources and is free to use the resources depending on the requirements and hence it is highly scalable.

Docker uses UNION File system .. Docker uses a copy-on-write technology to reduce the memory space consumed by containers. Read more here

You can also install simplejson.

If you have pip (see https://pypi.python.org/pypi/pip) as your Python package manager you can install simplejson with:

 pip install simplejson

This is similar to the comment of installing with easy_install, but I prefer pip to easy_install as you can easily uninstall in pip with "pip uninstall package".

The gradle included with Android Studio is located in /Applications/Android Studio.app/plugins/gradle/lib

To go into the Android Studio.app directory I did cd "Android Studio.app"

or you could just do cd /Applications/Android\ Studio.app/plugins/gradle/lib

In some circumstances it might be useful to simply remove the bindings and then re-apply:

ko.cleanNode(document.getElementById(element_id))
ko.applyBindings(viewModel, document.getElementById(element_id))

I had the same problem. I think the best solution is to use log.exception, which will automatically print out stack trace and error message, such as:

try:
    pass
    log.info('Success')
except:
    log.exception('Failed')

The Write-host work fine.

$Filesize = (Get-Item $filepath).length;
Write-Host "FileSize= $filesize";

1. Object* o; o = new Object();

2. Object* o = new Object();

Both these statement creates the object in the heap memory since you are creating the object using "new".

To be able to make the object creation happen in the stack, you need to follow this:

Object o;
Object *p = &o;

A bracket - [ or ] - means that end of the range is inclusive -- it includes the element listed. A parenthesis - ( or ) - means that end is exclusive and doesn't contain the listed element. So for [first1, last1), the range starts with first1 (and includes it), but ends just before last1.

Assuming integers:

• (0, 5) = 1, 2, 3, 4
• (0, 5] = 1, 2, 3, 4, 5
• [0, 5) = 0, 1, 2, 3, 4
• [0, 5] = 0, 1, 2, 3, 4, 5

I prefer Serializable = no boilerplate code. For passing data to other Fragments or Activities the speed difference to a Parcelable does not matter.

I would also always provide a helper method for a Fragment or Activity, this way you always know, what data has to be passed. Here an example for your ListMusicFragment:

private static final String EXTRA_MUSIC_LIST = "music_list";

public static ListMusicFragment createInstance(List<Music> music) {
    ListMusicFragment fragment = new ListMusicFragment();
    Bundle bundle = new Bundle();
    bundle.putSerializable(EXTRA_MUSIC_LIST, music);
    fragment.setArguments(bundle);
    return fragment;
}

@Override
public View onCreateView(...) { 
    ...
    Bundle bundle = intent.getArguments();
    List<Music> musicList = (List<Music>)bundle.getSerializable(EXTRA_MUSIC_LIST);
    ...
}

I'd like to point out few more solutions to transposing columns and rows in SQL.

The first one is - using CURSOR. Although the general consensus in the professional community is to stay away from SQL Server Cursors, there are still instances whereby the use of cursors is recommended. Anyway, Cursors present us with another option to transpose rows into columns.

• Vertical expansion

  Similar to the PIVOT, the cursor has the dynamic capability to append more rows as your dataset expands to include more policy numbers.

• Horizontal expansion

  Unlike the PIVOT, the cursor excels in this area as it is able to expand to include newly added document, without altering the script.

• Performance breakdown

  The major limitation of transposing rows into columns using CURSOR is a disadvantage that is linked to using cursors in general – they come at significant performance cost. This is because the Cursor generates a separate query for each FETCH NEXT operation.

Another solution of transposing rows into columns is by using XML.

The XML solution to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation.

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

• Vertical expansion

  Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

• Horizontal expansion

  Unlike the PIVOT, newly added documents can be displayed without altering the script.

• Performance breakdown

  In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

You don't need the date validator. It doesn't support dd/mm/yyyy format, and that's why you are getting "Please enter a valid date" message for input like 13/01/2014. You already have the dateITA validator, which uses dd/mm/yyyy format as you need.

Just like the date validator, your code for dateGreaterThan and dateLessThan calls new Date for input string and has the same issue parsing dates. You can use a function like this to parse the date:

function parseDMY(value) {
    var date = value.split("/");
    var d = parseInt(date[0], 10),
        m = parseInt(date[1], 10),
        y = parseInt(date[2], 10);
    return new Date(y, m - 1, d);
}

A void* can point to anything (it's a raw pointer without any type info).

Okay, this is still not the best possible solution, but a nice point to start. I wrote a little Java app that calculates the contrast ratio of two colors and only processes colors with a ratio of 5:1 or better - this ratio and the formula I use has been released by the W3C and will probably replace the current recommendation (which I consider very limited). It creates a file in the current working dir named "chosen-font-colors.html", with the background color of your choice and a line of text in every color that passed this W3C test. It expects a single argument, being the background color.

E.g. you can call it like this

java FontColorChooser 33FFB4

then just open the generated HTML file in a browser of your choice and choose a color from the list. All colors given passed the W3C test for this background color. You can change the cut off by replacing 5 with a number of your choice (lower numbers allow weaker contrasts, e.g. 3 will only make sure contrast is 3:1, 10 will make sure it is at least 10:1) and you can also cut off to avoid too high contrasts (by making sure it is smaller than a certain number), e.g. adding

|| cDiff > 18.0

to the if clause will make sure contrast won't be too extreme, as too extreme contrasts can stress your eyes. Here's the code and have fun playing around with it a bit :-)

import java.io.*;

/* For text being readable, it must have a good contrast difference. Why?
 * Your eye has receptors for brightness and receptors for each of the colors
 * red, green and blue. However, it has much more receptors for brightness
 * than for color. If you only change the color, but both colors have the
 * same contrast, your eye must distinguish fore- and background by the
 * color only and this stresses the brain a lot over the time, because it
 * can only use the very small amount of signals it gets from the color
 * receptors, since the breightness receptors won't note a difference.
 * Actually contrast is so much more important than color that you don't
 * have to change the color at all. E.g. light red on dark red reads nicely
 * even though both are the same color, red.

dt.Rows[1].ItemArray gives you a copy of item arrays. When you modify it, you're not modifying the original.

You can simply do this:

dt.Rows[1][3] = "Value";

ItemArray property is used when you want to modify all row values.

ex.:

dt.Rows[1].ItemArray = newItemArray;

A similar dex issue resolved method

gradle.build was containing:

compile files('libs/httpclient-4.2.1.jar')
compile 'org.apache.httpcomponents:httpclient:4.5'
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'

The issue was resolved when i removed

compile files('libs/httpclient-4.2.1.jar') 

My gradle now looks like:

apply plugin: 'com.android.application'

android {

compileSdkVersion 24
buildToolsVersion "24.0.3"

defaultConfig {
    applicationId "com.mmm.ll"
    minSdkVersion 16

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}
}

There was a redundancy in the JAR file and the compiled gradle project

So keenly look for dependency and jar files having same classes.

And remove redundancy.
This worked for me.

Swift 3.0 Full source code:

You should do mkdir build and cd build while inside opencv folder, not the opencv-contrib folder. The CMakeLists.txt is there.

As you can read before, the ?v=1 ensures that your browser gets the version 1 of the file. When you have a new version, you just have to append a different version number and the browser will forget about the old version and loads the new one.

There is a gulp plugin which takes care of version your files during the build phase, so you don't have to do it manually. It's handy and you can easily integrate it in you build process. Here's the link: gulp-annotate

Figured this out. Pretty simple:

 new PDO("sqlsrv:server=[sqlservername];Database=[sqlserverdbname]",  "[username]", "[password]");

you can put your elements into an array and hash at the same time.

var value = [1,2,3];
ahash = {"one": value};
array.push(value);

array can be used to get values by their order and hash could be used to get values by their key. just be be carryfull when you remove and add elements.

You can also delegate:

class Company < ActiveRecord::Base
  has_many :employees
  has_many :dogs, :through => :employees
end

class Employee < ActiveRescord::Base
  belongs_to :company
  has_many :dogs
end

class Dog < ActiveRecord::Base
  belongs_to :employee

  delegate :company, :to => :employee, :allow_nil => true
end

Like what has been mentioned before, pandas object is most efficient when process the whole array at once. However for those who really need to loop through a pandas DataFrame to perform something, like me, I found at least three ways to do it. I have done a short test to see which one of the three is the least time consuming.

t = pd.DataFrame({'a': range(0, 10000), 'b': range(10000, 20000)})
B = []
C = []
A = time.time()
for i,r in t.iterrows():
    C.append((r['a'], r['b']))
B.append(time.time()-A)

C = []
A = time.time()
for ir in t.itertuples():
    C.append((ir[1], ir[2]))    
B.append(time.time()-A)

C = []
A = time.time()
for r in zip(t['a'], t['b']):
    C.append((r[0], r[1]))
B.append(time.time()-A)

print B

Result:

[0.5639059543609619, 0.017839908599853516, 0.005645036697387695]

This is probably not the best way to measure the time consumption but it's quick for me.

Here are some pros and cons IMHO:

• .iterrows(): return index and row items in separate variables, but significantly slower
• .itertuples(): faster than .iterrows(), but return index together with row items, ir[0] is the index
• zip: quickest, but no access to index of the row

Elaborating on the answer provided by Brian R. Bondy: Here's an example that shows why you can't simply size the output buffer to the number of wide characters in the source string:

#include <windows.h>
#include <stdio.h>
#include <wchar.h>
#include <string.h>

/* string consisting of several Asian characters */
wchar_t wcsString[] = L"\u9580\u961c\u9640\u963f\u963b\u9644";

int main() 
{

    size_t wcsChars = wcslen( wcsString);

    size_t sizeRequired = WideCharToMultiByte( 950, 0, wcsString, -1, 
                                               NULL, 0,  NULL, NULL);

    printf( "Wide chars in wcsString: %u\n", wcsChars);
    printf( "Bytes required for CP950 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);

    sizeRequired = WideCharToMultiByte( CP_UTF8, 0, wcsString, -1,
                                        NULL, 0,  NULL, NULL);
    printf( "Bytes required for UTF8 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);
}

And the output:

Wide chars in wcsString: 6
Bytes required for CP950 encoding (excluding NUL terminator): 12
Bytes required for UTF8 encoding (excluding NUL terminator): 18

I just ran into a similar issue when I tried to commit to a newly created repo with a "." in it's name. I've seen several others have different issues with putting a "." in the repo name.

I just re-created the repo and

replaced "." with "-"

There may be other ways to resolve this, but this was a quick fix for me since it was a new repo.

There is actually special command for this job

npm ci

It will delete node_modules directory and will install packages with respect your package-lock.json file

More info: https://docs.npmjs.com/cli/ci.html

string(byteslice) will convert byte slice to string, just know that it's not only simply type conversion, but also memory copy.

You could float it, then it will only be as wide as its contents, but you'll have to make sure you clear those floats.

The envdir utility provides an easy way to do this. envdir uses files to represent environment variables, with file names mapping to env var names, and file contents mapping to env var values. If the file contents contain newlines, so will the env var.

See https://pypi.python.org/pypi/envdir

Detailed Answer

Problem

• Context: Python 2.x
• Scenario: Developer wishes modify a dictionary to exclude blank values
  • aka remove empty values from a dictionary
  • aka delete keys with blank values
  • aka filter dictionary for non-blank values over each key-value pair

Solution

• example01 use python list-comprehension syntax with simple conditional to remove "empty" values

Pitfalls

• example01 only operates on a copy of the original dictionary (does not modify in place)
• example01 may produce unexpected results depending on what developer means by "empty"
  • Does developer mean to keep values that are falsy?
  • If the values in the dictionary are not gauranteed to be strings, developer may have unexpected data loss.
  • result01 shows that only three key-value pairs were preserved from the original set

Alternate example

• example02 helps deal with potential pitfalls
• The approach is to use a more precise definition of "empty" by changing the conditional.
• Here we only want to filter out values that evaluate to blank strings.
• Here we also use .strip() to filter out values that consist of only whitespace.

Example02

### example02 -------------------

mydict  =   { "alpha":0,
              "bravo":"0",
              "charlie":"three",
              "delta":[],
              "echo":False,
              "foxy":"False",
              "golf":"",
              "hotel":"   ",
            }
newdict =   dict([(vkey, vdata) for vkey, vdata in mydict.iteritems() if(str(vdata).strip()) ])
print newdict

### result02 -------------------
result02 ='''
{'alpha': 0,
  'bravo': '0', 
  'charlie': 'three', 
  'delta': [],
  'echo': False,
  'foxy': 'False'
  }

That message isn't actually an error - it's just a warning that the file in question isn't of the right architecture (e.g. 32-bit vs 64-bit, wrong CPU architecture). The linker will keep looking for a library of the right type.

Of course, if you're also getting an error along the lines of can't find lPI-Http then you have a problem :-)

It's hard to suggest what the exact remedy will be without knowing the details of your build system and makefiles, but here are a couple of shots in the dark:

1. Just to check: usually you would add flags to CFLAGS rather than CTAGS - are you sure this is correct? (What you have may be correct - this will depend on your build system!)
2. Often the flag needs to be passed to the linker too - so you may also need to modify LDFLAGS

If that doesn't help - can you post the full error output, plus the actual command (e.g. gcc foo.c -m32 -Dxxx etc) that was being executed?

Made up example

Imagine that you want to create the following sequence: 1, 2, 2, 3, 3, 3, 4, 4, 4, 4 etc. (in other words: 1x1, 2x2, 3x3 etc.)

With flatMap it could look like:

IntStream sequence = IntStream.rangeClosed(1, 4)
                          .flatMap(i -> IntStream.iterate(i, identity()).limit(i));
sequence.forEach(System.out::println);

where:

• IntStream.rangeClosed(1, 4) creates a stream of int from 1 to 4, inclusive
• IntStream.iterate(i, identity()).limit(i) creates a stream of length i of int i - so applied to i = 4 it creates a stream: 4, 4, 4, 4
• flatMap "flattens" the stream and "concatenates" it to the original stream

With Java < 8 you would need two nested loops:

List<Integer> list = new ArrayList<>();
for (int i = 1; i <= 4; i++) {
    for (int j = 0; j < i; j++) {
        list.add(i);
    }
}

Real world example

Let's say I have a List<TimeSeries> where each TimeSeries is essentially a Map<LocalDate, Double>. I want to get a list of all dates for which at least one of the time series has a value. flatMap to the rescue:

list.stream().parallel()
    .flatMap(ts -> ts.dates().stream()) // for each TS, stream dates and flatmap
    .distinct()                         // remove duplicates
    .sorted()                           // sort ascending
    .collect(toList());

Not only is it readable, but if you suddenly need to process 100k elements, simply adding parallel() will improve performance without you writing any concurrent code.

The problem is actually that you need to double-escape backslashes in the replacement string. You see, "\\/" (as I'm sure you know) means the replacement string is \/, and (as you probably don't know) the replacement string \/ actually just inserts /, because Java is weird, and gives \ a special meaning in the replacement string. (It's supposedly so that \$ will be a literal dollar sign, but I think the real reason is that they wanted to mess with people. Other languages don't do it this way.) So you have to write either:

"Hello/You/There".replaceAll("/", "\\\\/");

or:

"Hello/You/There".replaceAll("/", Matcher.quoteReplacement("\\/"));

(Using java.util.regex.Matcher.quoteReplacement(String).)

If you wish to have an GUI based broker testing without installing any tool you can use Hive Mqtt web socket for testing your Mosquitto server

just visit http://www.hivemq.com/demos/websocket-client/ and enter server connection details.

If you got connected means your server is configured properly.

You can also test publish and subscribe of messages using this mqtt web socket

In PHP5, you should use the Document Object Model class instead. Example:

$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);

$subElt = $domDoc->createElement('foo');
$attr = $domDoc->createAttribute('ah');
$attrVal = $domDoc->createTextNode('OK');
$attr->appendChild($attrVal);
$subElt->appendChild($attr);
$subNode = $rootNode->appendChild($subElt);

$textNode = $domDoc->createTextNode('Wow, it works!');
$subNode->appendChild($textNode);

echo htmlentities($domDoc->saveXML());

AppStore will reject it, as it's reaching outside of application container.

Apps should be self-contained in their bundles, and may not read or write data outside the designated container area

Used Rn222's answer and aknuds1's answer to use an ISearchContext that returns either a single element, or a list. And a minimum number of elements can be specified:

public static class SearchContextExtensions
{
    /// <summary>
    ///     Method that finds an element based on the search parameters within a specified timeout.
    /// </summary>
    /// <param name="context">The context where this is searched. Required for extension methods</param>
    /// <param name="by">The search parameters that are used to identify the element</param>
    /// <param name="timeOutInSeconds">The time that the tool should wait before throwing an exception</param>
    /// <returns> The first element found that matches the condition specified</returns>
    public static IWebElement FindElement(this ISearchContext context, By by, uint timeOutInSeconds)
    {
        if (timeOutInSeconds > 0)
        {
            var wait = new DefaultWait<ISearchContext>(context);
            wait.Timeout = TimeSpan.FromSeconds(timeOutInSeconds);
            return wait.Until<IWebElement>(ctx => ctx.FindElement(by));
        }
        return context.FindElement(by);
    }
    /// <summary>
    ///     Method that finds a list of elements based on the search parameters within a specified timeout.
    /// </summary>
    /// <param name="context">The context where this is searched. Required for extension methods</param>
    /// <param name="by">The search parameters that are used to identify the element</param>
    /// <param name="timeoutInSeconds">The time that the tool should wait before throwing an exception</param>
    /// <returns>A list of all the web elements that match the condition specified</returns>
    public static IReadOnlyCollection<IWebElement> FindElements(this ISearchContext context, By by, uint timeoutInSeconds)
    {

        if (timeoutInSeconds > 0)
        {
            var wait = new DefaultWait<ISearchContext>(context);
            wait.Timeout = TimeSpan.FromSeconds(timeoutInSeconds);
            return wait.Until<IReadOnlyCollection<IWebElement>>(ctx => ctx.FindElements(by));
        }
        return context.FindElements(by);
    }
    /// <summary>
    ///     Method that finds a list of elements with the minimum amount specified based on the search parameters within a specified timeout.<br/>
    /// </summary>

    ///     If this number is not met, an exception will be thrown and no elements will be returned
    ///     even if some did meet the criteria
    /// </param>
    /// <returns>A list of all the web elements that match the condition specified</returns>
    public static IReadOnlyCollection<IWebElement> FindElements(this ISearchContext context, By by, uint timeoutInSeconds, int minNumberOfElements)
    {
        var wait = new DefaultWait<ISearchContext>(context);
        if (timeoutInSeconds > 0)
        {
            wait.Timeout = TimeSpan.FromSeconds(timeoutInSeconds);
        }

        // Wait until the current context found the minimum number of elements. If not found after timeout, an exception is thrown
        wait.Until<bool>(ctx => ctx.FindElements(by).Count >= minNumberOfElements);

        // If the elements were successfuly found, just return the list
        return context.FindElements(by);
    }

}

Example usage:

var driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://localhost");
var main = driver.FindElement(By.Id("main"));
// It can be now used to wait when using elements to search
var btn = main.FindElement(By.Id("button"), 10);
btn.Click();
// This will wait up to 10 seconds until a button is found
var button = driver.FindElement(By.TagName("button"), 10)
// This will wait up to 10 seconds until a button is found, and return all the buttons found
var buttonList = driver.FindElements(By.TagName("button"), 10)
// This will wait for 10 seconds until we find at least 5 buttons
var buttonsMin = driver.FindElements(By.TagName("button"), 10, 5);
driver.Close();

After looking for so many answers on StackOverflow, I haven't seen an answer to fit my needs.

That is, to make top command to keep refreshing with given keyword, and we don't have to CTRL+C / top again and again when new processes spawn.

Thus I make a new one...

Here goes the no-restart-needed version.

__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; sleep 1; done;)

Modify the __keyword and it should works. (Ubuntu 2.6.38 tested)

2.14.2015 added: The system workload part is missing with the code above. For people who cares about the "load average" part:

__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; uptime; sleep 1; done;)

A solution for the related case where you have an include file A that you can edit and want to override some of its functions in an include file B (or the main file):

Main File:

<?php
$Override=true; // An argument used in A.php
include ("A.php");
include ("B.php");
F1();
?>

Include File A:

<?php
if (!@$Override) {
   function F1 () {echo "This is F1() in A";}
}
?>

Include File B:

<?php
   function F1 () {echo "This is F1() in B";}
?>

Browsing to the main file displays "This is F1() in B".

A shorter version of the accepted answer using Guava:

.getMap(Iterables.toArray(locations, WorldLocation.class));

can be shortened further by statically importing toArray:

import static com.google.common.collect.toArray;
// ...

    .getMap(toArray(locations, WorldLocation.class));

I would do that like this. It's a lot of code but it ensures, that the textField currently in focus is is vertically centered in the 'available space':

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

- (void)keyboardWillShow:(NSNotification *)notification {
    NSDictionary *info = [notification userInfo];
    NSValue *keyBoardEndFrame = [info objectForKey:UIKeyboardFrameEndUserInfoKey];
    CGSize keyboardSize = [keyBoardEndFrame CGRectValue].size;
    self.keyboardSize = keyboardSize;

    [self adjustScrollViewOffsetToCenterTextField:self.currentTextField];
}

- (void)keyboardWillHide:(NSNotification *)notification {
    self.keyboardSize = CGSizeZero;
}

- (IBAction)textFieldGotFocus:(UITextField *)sender {
    sender.inputAccessoryView = self.keyboardAccessoryView;
    self.currentTextField = sender;
    [self adjustScrollViewOffsetToCenterTextField:sender];    
}

- (void)adjustScrollViewOffsetToCenterTextField:(UITextField *)textField
{
    CGRect textFieldFrame = textField.frame;
    float keyboardHeight = MIN(self.keyboardSize.width, self.keyboardSize.height);

    float visibleScrollViewHeight = self.scrollView.frame.size.height - keyboardHeight;
    float offsetInScrollViewCoords = (visibleScrollViewHeight / 2) - (textFieldFrame.size.height / 2);

    float scrollViewOffset = textFieldFrame.origin.y - offsetInScrollViewCoords;


    [UIView animateWithDuration:.3 delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:^{
        self.scrollView.contentOffset = CGPointMake(self.scrollView.contentOffset.x, scrollViewOffset);
    }completion:NULL];

}

you'll need these two properties in your @interface...
@property (nonatomic, assign) CGSize keyboardSize;
@property (nonatomic, strong) UITextField *currentTextField;

Note that the - (IBAction)textFieldGotFocus: action is hooked up to the every textField's DidBeginEditing state.

Also it would be a little better to get the animation duration from the keyboard notification and use that for the scrollview animation instead of a fixed value, but sue me, this was good enough for me ;)

If it is related to the SSIS Package check may be possible that your source db contains few null rows. After removing them this issue will not appear any more.

The only software that I found that already exists is Matrox PowerDesk. Among other things it lets you split a monitor into 2 virtual desktops. You have to have a compatible matrox video card though. It also does a bunch of other multi-monitor functions.

another great and easy way is to have a blind modal in your layout and call it if neccessary.

JS

  var remote_modal = function(url) {
    // reset modal body with a spinner or empty content
    spinner = "<div class='text-center'><i class='fa fa-spinner fa-spin fa-5x fa-fw'></i></div>"

    $("#remote-modal .modal-body").html(spinner)
    $("#remote-modal .modal-body").load(url);
    $("#remote-modal").modal("show");
  }

and your HTML

 <div class='modal fade' id='remote-modal'>
    <div class='modal-dialog modal-lg'>
      <div class='modal-content'>
        <div class='modal-body'></div>
        <div class='modal-footer'>
          <button class='btn btn-default'>Close</button>
        </div>
      </div>
    </div>
  </div>
</body>

now you can simply call remote_modal('/my/url.html') and the content gets displayed inside of the modal

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

Got around this issue by using the moment.js library (the non-timezone version).

var newMinDate = moment(datePicker.selectedDates[0]);
var newMaxDate = moment(datePicker.selectedDates[1]);

// Define the data to ask the server for

Adding libraries with resources To add a Support Library with resources (such as v7 appcompat for action bar) to your application project:

Using Eclipse

Create a library project based on the support library code:

• Make sure you have downloaded the Android Support Library using the SDK Manager.

• Create a library project and ensure the required JAR files are included in the project's build path:

• Select File > Import.

• Select Existing Android Code Into Workspace and click Next.

• Browse to the SDK installation directory and then to the Support Library folder. For example, if you are adding the appcompat project, browse to /extras/android/support/v7/appcompat/.

• Click Finish to import the project. For the v7 appcompat project, you should now see a new project titled android-support-v7-appcompat.

• In the new library project, expand the libs/ folder, right-click each .jar file and select Build

• Path > Add to Build Path. For example, when creating the the v7 appcompat project, add both the android-support-v4.jar and android-support-v7-appcompat.jar files to the build path.

• Right-click the library project folder and select Build Path > Configure Build Path.

• In the Order and Export tab, check the .jar files you just added to the build path, so they are available to projects that depend on this library project. For example, the appcompat project requires you to export both the android-support-v4.jar and android-support-v7-appcompat.jar files.

• Uncheck Android Dependencies.

• Click OK to complete the changes.

• You now have a library project for your selected Support Library that you can use with one or more application projects.

• Add the library to your application project:

• In the Project Explorer, right-click your project and select Properties.

• In the category panel on the left side of the dialog, select Android.

• In the Library pane, click the Add button.

• Select the library project and click OK. For example, the appcompat project should be listed as android-support-v7-appcompat.

• In the properties window, click OK.

Wrapping your list of objects with another object containing a property that matches the name of the parameter which is expected by the MVC controller works. The important bit being the wrapper around the object list.

$(document).ready(function () {
    var employeeList = [
        { id: 1, name: 'Bob' },
        { id: 2, name: 'John' },
        { id: 3, name: 'Tom' }
    ];      

    var Employees = {
      EmployeeList: employeeList
    }

    $.ajax({
        dataType: 'json',
        type: 'POST',
        url: '/Employees/Process',
        data: Employees,
        success: function () {          
            $('#InfoPanel').html('It worked!');
        },
        failure: function (response) {          
            $('#InfoPanel').html(response);
        }
    }); 
});


public void Process(List<Employee> EmployeeList)
{
    var emps = EmployeeList;
}

public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
}

Quick-to-write alterantive

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

Review the pom.xml file inside of target/checkout/. Chances are, the pom.xml in your trunk or master branch does not have the distributionManagement tag.

ASP.NET Web API uses Json.Net as default formatter, so if your application just only uses JSON as data format, you can use [JsonIgnore] to ignore property for serialization:

public class Foo
{
    public int Id { get; set; }
    public string Name { get; set; }

    [JsonIgnore]
    public List<Something> Somethings { get; set; }
}

But, this way does not support XML format. So, in case your application has to support XML format more (or only support XML), instead of using Json.Net, you should use [DataContract] which supports both JSON and XML:

[DataContract]
public class Foo
{
    [DataMember]
    public int Id { get; set; }
    [DataMember]
    public string Name { get; set; }

    //Ignore by default
    public List<Something> Somethings { get; set; }
}

For more understanding, you can read the official article.

1. Generate a random number using your favourite random-number generator
2. Multiply and divide it to get a number matching the number of characters in your code alphabet
3. Get the item at that index in your code alphabet.
4. Repeat from 1) until you have the length you want

e.g (in pseudo code)

int myInt = random(0, numcharacters)
char[] codealphabet = 'ABCDEF12345'
char random = codealphabet[i]
repeat until long enough

There are lot of incomplete answers here. Since you cannot apply a border to tr tag, you need to apply it to the td or th tags like so:

td {
  border-bottom: 1pt solid black;
}

Doing this will leave a small space between each td, which is likely not desirable if you want the border to appear as though it is the tr tag. In order to "fill in the gaps" so to speak, you need to utilize the border-collapse property on the table element and set its value to collapse, like so:

table {
  border-collapse: collapse;
}

A Type agnostic solution:

for _, key := range reflect.ValueOf(yourMap).MapKeys() {
    value := s.MapIndex(key).Interface()
    fmt.Println("Key:", key, "Value:", value)
}  

Here's a simpler(short) solution to check for empty variables. This function checks if a variable is empty. The variable provided may contain mixed values (null, undefined, array, object, string, integer, function).

function empty(mixed_var) {
 if (!mixed_var || mixed_var == '0') {
  return true;
 }
 if (typeof mixed_var == 'object') {
  for (var k in mixed_var) {
   return false;
  }
  return true;
 }
 return false;
}

//   example 1: empty(null);
//   returns 1: true

//   example 2: empty(undefined);
//   returns 2: true

//   example 3: empty([]);
//   returns 3: true

//   example 4: empty({});
//   returns 4: true

//   example 5: empty(0);
//   returns 5: true

//   example 6: empty('0');
//   returns 6: true

//   example 7: empty(function(){});
//   returns 7: false

The following solution is inspired by the SocketUtils implementation of Spring-core (Apache license).

Compared to other solutions using Socket(...) it is pretty fast (testing 1000 TCP ports in less than a second):

public static boolean isTcpPortAvailable(int port) {
    try (ServerSocket serverSocket = new ServerSocket()) {
        // setReuseAddress(false) is required only on OSX, 
        // otherwise the code will not work correctly on that platform          
        serverSocket.setReuseAddress(false);
        serverSocket.bind(new InetSocketAddress(InetAddress.getByName("localhost"), port), 1);
        return true;
    } catch (Exception ex) {
        return false;
    }
}       

#include <iostream>
#include <string>
#include <sstream>
int main(){
    std::string myText("some-text-to-tokenize");
    std::istringstream iss(myText);
    std::string token;
    while (std::getline(iss, token, '-'))
    {
        std::cout << token << std::endl;
    }
    return 0;
}

Or, as mentioned, use boost for more flexibility.

In my instance of the problem, the solution was to replace german umlauts (äöü) with their HTML-equivalents...

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

pip has a --no-dependencies switch. You should use that.

For more information, run pip install -h, where you'll see this line:

--no-deps, --no-dependencies
                        Ignore package dependencies

You can create a symbolic link with a shorter directory. First open command line for example by Shift + RightClick in your desired folder with a shorter path (you may have to run it as administrator).

Then type with relative or absolute paths:

mklink ShortPath\To\YourLinkedSolution C:\Path\To\Your\Solution /D

And then start the Solution from the shorter path. The advantage here is: You don't have to move anything.

I would suggest looking into javax.swing.JFileChooser

Here is a site with some examples in using as both 'Open' and 'Save'. http://www.java2s.com/Code/Java/Swing-JFC/DemonstrationofFiledialogboxes.htm

Your @Entity class has a String type for its @Id field, so it can't generate ids for you.

If you change it to an auto increment in the DB and a Long in java, and add the @GeneratedValue annotation:

@Id
@Column(name="U_id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long U_id;

it will handle incrementing id generation for you.

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Example

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

Available on npm as escape-string-regexp

npm install --save escape-string-regexp

See MDN: Javascript Guide: Regular Expressions

Other symbols (~`!@# ...) MAY be escaped without consequence, but are not required to be.

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

You do cls.isFilled = True. That overwrites the method called isFilled and replaces it with the value True. That method is now gone and you can't call it anymore. So when you try to call it again you get an error, since it's not there anymore.

The solution is use a different name for the variable than you do for the method.

create a class create a object globally and call this

using System.IO;
using System.Reflection;


   public class LogWriter
{
    private string m_exePath = string.Empty;
    public LogWriter(string logMessage)
    {
        LogWrite(logMessage);
    }
    public void LogWrite(string logMessage)
    {
        m_exePath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
        try
        {
            using (StreamWriter w = File.AppendText(m_exePath + "\\" + "log.txt"))
            {

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

@Marcin: awk example non-greedy:

awk '{if ($0 ~ /Start pattern/) {triggered=1;}if (triggered) {print; if ($0 ~ /End pattern/) { exit;}}}' filename

My requirements included:

• must honor the dataContracts
• must deserialize dates in the format received in service
• must handle colelctions
• must target 3.5
• must NOT add an external dependency, especially not Newtonsoft (I'm creating a distributable package myself)
• must not be deserialized by hand

My solution in the end was to use SimpleJson(https://github.com/facebook-csharp-sdk/simple-json).

Although you can install it via a nuget package, I included just that single SimpleJson.cs file (with the MIT license) in my project and referenced it.

I hope this helps someone.

To execute 'php' code inside 'html' or 'htm', for 'apache version 2.4.23'

Go to '/etc/apache2/mods-enabled' edit '@mime.conf'

Go to end of file and add the following line:

 "AddType application/x-httpd-php .html .htm"

BEFORE tag '< /ifModules >' verified and tested with 'apache 2.4.23' and 'php 5.6.17-1' under 'debian'

Let's suppose these values for common_id:

Common - 1
Table1 - 2
Table2 - 3, null

We want the row in Common to return, because it doesn't exist in any of the other tables. However, the null throws in a monkey wrench.

With those values, the query is equivalent to:

select *
from Common
where 1 not in (2)
and 1 not in (3, null)

That is equivalent to:

select *
from Common
where not (1=2)
and not (1=3 or 1=null)

This is where the problem starts. When comparing with a null, the answer is unknown. So the query reduces to

select *
from Common
where not (false)
and not (false or unkown)

false or unknown is unknown:

select *
from Common
where true
and not (unknown)

true and not unkown is also unkown:

select *
from Common
where unknown

The where condition does not return records where the result is unkown, so we get no records back.

One way to deal with this is to use the exists operator rather than in. Exists never returns unkown because it operates on rows rather than columns. (A row either exists or it doesn't; none of this null ambiguity at the row level!)

select *
from Common
where not exists (select common_id from Table1 where common_id = Common.common_id)
and not exists (select common_id from Table2 where common_id = Common.common_id)

The PHP equivalent is time(): http://php.net/manual/en/function.time.php

What does copying an object mean? There are a few ways you can copy objects--let's talk about the 2 kinds you're most likely referring to--deep copy and shallow copy.

Since we're in an object-oriented language (or at least are assuming so), let's say you have a piece of memory allocated. Since it's an OO-language, we can easily refer to chunks of memory we allocate because they are usually primitive variables (ints, chars, bytes) or classes we defined that are made of our own types and primitives. So let's say we have a class of Car as follows:

class Car //A very simple class just to demonstrate what these definitions mean.
//It's pseudocode C++/Javaish, I assume strings do not need to be allocated.
{
private String sPrintColor;
private String sModel;
private String sMake;

public changePaint(String newColor)
{
   this.sPrintColor = newColor;
}

public Car(String model, String make, String color) //Constructor
{
   this.sPrintColor = color;
   this.sModel = model;
   this.sMake = make;
}

public ~Car() //Destructor
{
//Because we did not create any custom types, we aren't adding more code.
//Anytime your object goes out of scope / program collects garbage / etc. this guy gets called + all other related destructors.
//Since we did not use anything but strings, we have nothing additional to handle.
//The assumption is being made that the 3 strings will be handled by string's destructor and that it is being called automatically--if this were not the case you would need to do it here.
}

public Car(const Car &other) // Copy Constructor
{
   this.sPrintColor = other.sPrintColor;
   this.sModel = other.sModel;
   this.sMake = other.sMake;
}
public Car &operator =(const Car &other) // Assignment Operator
{
   if(this != &other)
   {
      this.sPrintColor = other.sPrintColor;
      this.sModel = other.sModel;
      this.sMake = other.sMake;
   }
   return *this;
}

}

A deep copy is if we declare an object and then create a completely separate copy of the object...we end up with 2 objects in 2 completely sets of memory.

Car car1 = new Car("mustang", "ford", "red");
Car car2 = car1; //Call the copy constructor
car2.changePaint("green");
//car2 is now green but car1 is still red.

Now let's do something strange. Let's say car2 is either programmed wrong or purposely meant to share the actual memory that car1 is made of. (It's usually a mistake to do this and in classes is usually the blanket it's discussed under.) Pretend that anytime you ask about car2, you're really resolving a pointer to car1's memory space...that's more or less what a shallow copy is.

//Shallow copy example
//Assume we're in C++ because it's standard behavior is to shallow copy objects if you do not have a constructor written for an operation.
//Now let's assume I do not have any code for the assignment or copy operations like I do above...with those now gone, C++ will use the default.

 Car car1 = new Car("ford", "mustang", "red"); 
 Car car2 = car1; 
 car2.changePaint("green");//car1 is also now green 
 delete car2;/*I get rid of my car which is also really your car...I told C++ to resolve 
 the address of where car2 exists and delete the memory...which is also
 the memory associated with your car.*/
 car1.changePaint("red");/*program will likely crash because this area is
 no longer allocated to the program.*/

So regardless of what language you're writing in, be very careful about what you mean when it comes to copying objects because most of the time you want a deep copy.

What are the copy constructor and the copy assignment operator? I have already used them above. The copy constructor is called when you type code such as Car car2 = car1; Essentially if you declare a variable and assign it in one line, that's when the copy constructor is called. The assignment operator is what happens when you use an equal sign--car2 = car1;. Notice car2 isn't declared in the same statement. The two chunks of code you write for these operations are likely very similar. In fact the typical design pattern has another function you call to set everything once you're satisfied the initial copy/assignment is legitimate--if you look at the longhand code I wrote, the functions are nearly identical.

When do I need to declare them myself? If you are not writing code that is to be shared or for production in some manner, you really only need to declare them when you need them. You do need to be aware of what your program language does if you choose to use it 'by accident' and didn't make one--i.e. you get the compiler default. I rarely use copy constructors for instance, but assignment operator overrides are very common. Did you know you can override what addition, subtraction, etc. mean as well?

How can I prevent my objects from being copied? Override all of the ways you're allowed to allocate memory for your object with a private function is a reasonable start. If you really don't want people copying them, you could make it public and alert the programmer by throwing an exception and also not copying the object.

Technical differences are a consequence of the goal of each one (OpenJDK is meant to be the reference implementation, open to the community, while Oracle is meant to be a commercial one)

They both have "almost" the same code of the classes in the Java API; but the code for the virtual machine itself is actually different, and when it comes to libraries, OpenJDK tends to use open libraries while Oracle tends to use closed ones; for instance, the font library.

Despite all the great answers above and due to me being new to Django, I was still stuck. Here's my explanation from a very newbie perspective.

models.py

class Author(models.Model):
    name = models.CharField(max_length=255)

class Book(models.Model):
    author = models.ForeignKey(Author)
    title = models.CharField(max_length=255)

admin.py (Incorrect Way) - you think it would work by using 'model__field' to reference, but it doesn't

class BookAdmin(admin.ModelAdmin):
    model = Book
    list_display = ['title', 'author__name', ]

admin.site.register(Book, BookAdmin)

admin.py (Correct Way) - this is how you reference a foreign key name the Django way

class BookAdmin(admin.ModelAdmin):
    model = Book
    list_display = ['title', 'get_name', ]

    def get_name(self, obj):
        return obj.author.name
    get_name.admin_order_field  = 'author'  #Allows column order sorting
    get_name.short_description = 'Author Name'  #Renames column head

    #Filtering on side - for some reason, this works
    #list_filter = ['title', 'author__name']

admin.site.register(Book, BookAdmin)

For additional reference, see the Django model link here

None of these answers worked for me, I had to do the following:

1. Start Menu > type 'Internet Options'.
2. Select Local intranet zone on the Security tab then click the Sites button
3. Click Advanced button
4. Enter file://[computer name]
5. Make sure 'Require server verification...' is unticked

Just wanted to add some info that, we can check this info whether git pull automatically refers to any branch or not.

If you run the command, git remote show origin, (assuming origin as the short name for remote), git shows this info, whether any default reference exists for git pull or not.

Below is a sample output.(taken from git documentation).

$ git remote show origin
* remote origin
  Fetch URL: https://github.com/schacon/ticgit
  Push  URL: https://github.com/schacon/ticgit
  HEAD branch: master
  Remote branches:
    master                               tracked
    dev-branch                           tracked
  Local branch configured for 'git pull':
    master merges with remote master
  Local ref configured for 'git push':
    master pushes to master (up to date)

Please note the part where it shows, Local branch configured for git pull.

In this case, git pull will refer to git pull origin master

Initially, if you have cloned the repository, using git clone, these things are automatically taken care of. But if you have added a remote manually using git remote add, these are missing from the git config. If that is the case, then the part where it shows "Local branch configured for 'git pull':", would be missing from the output of git remote show origin.

The next steps to follow if no configuration exists for git pull, have already been explained by other answers.

Try to get using:

var count = $("ul > li").size();
alert(count);

[System.Security.Principal.WindowsIdentity]::GetCurrent().Name

I don't like absolute positioning, either, because there is almost always some collateral damage, i.e. unintended side effects. Especially when you are working with a responsive design. There seems to be an alternative - the sandbag technique. By inserting a "helper" element, either in the markup of via CSS, we can push elements down to the bottom of the container. See http://community.sitepoint.com/t/css-floating-divs-to-the-bottom-inside-a-div/20932 for examples.

You can use scriptlets, however, this is not the way to go. Nowdays inline scriplets or JAVA code in your JSP files is considered a bad habit.

You should read up on JSTL a bit more. If the ansokanInfo object is in your request or session scope, printing the object (toString() method) like this: ${ansokanInfo} can give you some base information. ${ansokanInfo.pSystem} should call the object getter method. If this all works, you can use this:

<c:if test="${ ansokanInfo.pSystem  == 'NAT'}"> tataa </c:if>

I have the same problem. I use DateTime.Parse Method. and in the URL use this format to pass my DateTime parameter 2018-08-18T07:22:16

for more information about using DateTime Parse method refer to this link : DateTime Parse Method

string StringDateToDateTime(string date)
    {
        DateTime dateFormat = DateTime.Parse(date);
        return dateFormat ;
    }

I hope this link helps you.

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

To check if a grammar is LL(1), one option is to construct the LL(1) parsing table and check for any conflicts. These conflicts can be

• FIRST/FIRST conflicts, where two different productions would have to be predicted for a nonterminal/terminal pair.
• FIRST/FOLLOW conflicts, where two different productions are predicted, one representing that some production should be taken and expands out to a nonzero number of symbols, and one representing that a production should be used indicating that some nonterminal should be ultimately expanded out to the empty string.
• FOLLOW/FOLLOW conflicts, where two productions indicating that a nonterminal should ultimately be expanded to the empty string conflict with one another.

Let's try this on your grammar by building the FIRST and FOLLOW sets for each of the nonterminals. Here, we get that

FIRST(X) = {a, b, z}
FIRST(Y) = {b, epsilon}
FIRST(Z) = {epsilon} 

We also have that the FOLLOW sets are

FOLLOW(X) = {$}
FOLLOW(Y) = {z}
FOLLOW(Z) = {z}

From this, we can build the following LL(1) parsing table:

    a    b    z   $
X   a    Yz   Yz  
Y        bZ   eps
Z             eps

Since we can build this parsing table with no conflicts, the grammar is LL(1).

To check if a grammar is LR(0) or SLR(1), we begin by building up all of the LR(0) configurating sets for the grammar. In this case, assuming that X is your start symbol, we get the following:

(1)
X' -> .X
X -> .Yz
X -> .a
Y -> .
Y -> .bZ

(2)
X' -> X.

(3)
X -> Y.z

(4)
X -> Yz.

(5)
X -> a.

(6)
Y -> b.Z
Z -> .

(7)
Y -> bZ.

From this, we can see that the grammar is not LR(0) because there are shift/reduce conflicts in states (1) and (6). Specifically, because we have the reduce items Z → . and Y → ., we can't tell whether to reduce the empty string to these symbols or to shift some other symbol. More generally, no grammar with ε-productions is LR(0).

However, this grammar might be SLR(1). To see this, we augment each reduction with the lookahead set for the particular nonterminals. This gives back this set of SLR(1) configurating sets:

(1)
X' -> .X
X -> .Yz [$]
X -> .a  [$]
Y -> .   [z]
Y -> .bZ [z]

(2)
X' -> X.

(3)
X -> Y.z [$]

(4)
X -> Yz. [$]

(5)
X -> a.  [$]

(6)
Y -> b.Z [z]
Z -> .   [z]

(7)
Y -> bZ. [z]

Now, we don't have any more shift-reduce conflicts. The conflict in state (1) has been eliminated because we only reduce when the lookahead is z, which doesn't conflict with any of the other items. Similarly, the conflict in (6) is gone for the same reason.

Hope this helps!

Now in rails 5 yu can do:

rails restart

This print by rails --tasks

Restart app by touching tmp/restart.txt

I think that is usefully if you run rails as a demon

$web_url = 'http://www.writephponline.com?name=shubham&[email protected]';
$query = parse_url($web_url, PHP_URL_QUERY);
parse_str($query, $queryArray);

echo "Name: " . $queryArray['name'];  // Result: shubham
echo "EMail: " . $queryArray['email']; // Result:[email protected]

You are looking for str.rsplit(), with a limit:

print x.rsplit('-', 1)[0]

.rsplit() searches for the splitting string from the end of input string, and the second argument limits how many times it'll split to just once.

Another option is to use str.rpartition(), which will only ever split just once:

print x.rpartition('-')[0]

For splitting just once, str.rpartition() is the faster method as well; if you need to split more than once you can only use str.rsplit().

Demo:

>>> x = 'http://test.com/lalala-134'
>>> print x.rsplit('-', 1)[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rsplit('-', 1)[0]
'something-with-a-lot-of'

and the same with str.rpartition()

>>> print x.rpartition('-')[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rpartition('-')[0]
'something-with-a-lot-of'

you need to replace "/" with "7", it works on non english keyboard layout.

Assuming you have Python2.7 installed

1. Goto the Start Menu

2. Right Click "Computer"

3. Select "Properties"

4. A dialog should pop up with a link on the left called "Advanced system settings". Click it.

5. In the System Properties dialog, click the button called "Environment Variables".

6. In the Environment Variables dialog look for "Path" under the System Variables window.

7. Add ";C:\Python27" to the end of it. The semicolon is the path separator on windows.

8. Click Ok and close the dialogs.

9. Now open up a new command prompt and type "python"

It should work.

h5py provides a model of datasets and groups. The former is basically arrays and the latter you can think of as directories. Each is named. You should look at the documentation for the API and examples:

http://docs.h5py.org/en/latest/quick.html

A simple example where you are creating all of the data upfront and just want to save it to an hdf5 file would look something like:

In [1]: import numpy as np
In [2]: import h5py
In [3]: a = np.random.random(size=(100,20))
In [4]: h5f = h5py.File('data.h5', 'w')
In [5]: h5f.create_dataset('dataset_1', data=a)
Out[5]: <HDF5 dataset "dataset_1": shape (100, 20), type "<f8">

In [6]: h5f.close()

You can then load that data back in using: '

In [10]: h5f = h5py.File('data.h5','r')
In [11]: b = h5f['dataset_1'][:]
In [12]: h5f.close()

In [13]: np.allclose(a,b)
Out[13]: True

Definitely check out the docs:

http://docs.h5py.org

Writing to hdf5 file depends either on h5py or pytables (each has a different python API that sits on top of the hdf5 file specification). You should also take a look at other simple binary formats provided by numpy natively such as np.save, np.savez etc:

http://docs.scipy.org/doc/numpy/reference/routines.io.html

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

Just Cast Column As Varchar(Size)

If both Column are numeric then use code below.

Example:

Select (Cast(Col1 as Varchar(20)) + '-' + Cast(Col2 as Varchar(20))) As Col3 from Table

What will be the size of col3 it will be 40 or something else

This approach, fixed up, will give the correct output (it's highly inefficient, but that's not a problem unless you're scaling up dramatically.)

int[] array = { 10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12 };
for (int i = 0; i < array.Length; i++)
{
    int count = 0;
    for (int j = 0; j < array.Length ; j++)
    {
       if(array[i] == array[j])
          count = count + 1;
    }
    Console.WriteLine("\t\n " + array[i] + " occurs " + count);
    Console.ReadKey();
}

I counted 5 errors in the OP code, noted below.

int[] array = { 10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12 };
int count = 1;                                   // 1. have to put "count" in the inner loop so it gets reset
                                                 // 2. have to start count at 0
for (int i = 0; i < array.Length; i++)
{
    for (int j = i; j < array.Length - 1 ; j++)  // 3. have to cover the entire loop
                                                 // for (int j=0 ; j<array.Length ; j++)
    {
       if(array[j] == array[j+1])                // 4. compare outer to inner loop values
                                                 // if (array[i] == array[j])
          count = count + 1;
    }
    Console.WriteLine("\t\n " + array[i] + "occurse" + count);
                                                 // 5. It's spelled "occurs" :)
    Console.ReadKey();
}

Edit

For a better approach, use a Dictionary to keep track of the counts. This allows you to loop through the array just once, and doesn't print duplicate counts to the console.

var counts = new Dictionary<int, int>();
int[] array = { 10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12 };
for (int i = 0; i < array.Length; i++)
{
    int currentVal = array[i];
    if (counts.ContainsKey(currentVal))
        counts[currentVal]++;
    else
        counts[currentVal] = 1;
}
foreach (var kvp in counts)
    Console.WriteLine("\t\n " + kvp.Key + " occurs " + kvp.Value);

your exists syntax is wrong and you should seperate DDL with go like below

if exists(select 1 from sys.views where name='tst' and type='v')
drop view tst;
go

create view tst
as
select * from test

you also can check existence test, with object_id like below

if object_id('tst','v') is not null
drop view tst;
go

create view tst
as
select * from test

In SQL 2016,you can use below syntax to drop

Drop view  if exists dbo.tst

From SQL2016 CU1,you can do below

create or alter view vwTest
as
 select 1 as col;
go

1. Navigate to C:\Users\username\Documents\IISExpress\config
2. Open applicationhost.config with Visual Studio or your favorite text-editor.
3. Search for the word mimeMap, you should find lots of 'em.
4. Add the following line to the top of the list: .

To upgrade all local packages; you could use pip-review:

$ pip install pip-review
$ pip-review --local --interactive

pip-review is a fork of pip-tools. See pip-tools issue mentioned by @knedlsepp. pip-review package works but pip-tools package no longer works.

pip-review works on Windows since version 0.5.
