If, like me, you can't find a datetime under date or time in the format dialog, you should be able to find it in 'Custom'.

I just selected 'dd/mm/yyyy hh:mm' from 'Custom' and am happy with the results.

You can use also the Insert/update/delete datagrid of my MVC Controls Toolkit available here on codeplex: http://mvccontrolstoolkit.codeplex.com/. Here you can download a complete example, here the datagrid working and here and here tutorials. The DataGrid works completely client side and mantains thechange set between posts. Yes it mantains Changeset, this means, you can access both old version and modified version of each record to see what changes to pass to the DB(what need to be modified deleted or inserted). This Changeset is mantained after several posts till you either confirm or cancel the modifications on the server side.

A technique I use is something like the following. Define a global variable that you can use for one or multiple try catch blocks depending on what you're trying to debug and use the following structure:

if(!GlobalTestingBool)
{
   try
   {
      SomeErrorProneMethod();
   }
   catch (...)
   {
      // ... Error handling ...
   }
}
else
{
   SomeErrorProneMethod();
}

I find this gives me a bit more flexibility in terms of testing because there are still some exceptions I don't want the IDE to break on.

Simple SQL triggered API call without building a code project

I know this is far from perfect or architectural purity, but I had a customer with a short term, critical need to integrate with a third party product via an immature API (no wsdl) I basically needed to call the API when a database event occurred. I was given basic call info - URL, method, data elements and Token, but no wsdl or other start to import into a code project. All recommendations and solutions seemed start with that import.

I used the ARC (Advanced Rest Client) Chrome extension and JaSON to test the interaction with the Service from a browser and refine the call. That gave me the tested, raw call structure and response and let me play with the API quickly. From there, I started trying to generate the wsdl or xsd from the json using online conversions but decided that was going to take too long to get working, so I found cURL (clouds part, music plays). cURL allowed me to send the API calls to a local manager from anywhere. I then broke a few more design rules and built a trigger that queued the DB events and a SQL stored procedure and scheduled task to pass the parameters to cURL and make the calls. I initially had the trigger calling XP_CMDShell (I know, booo) but didn't like the transactional implications or security issues, so switched to the Stored Procedure method.

In the end, DB insert matching the API call case triggers write to Queue table with parameters for API call Stored procedure run every 5 seconds runs Cursor to pull each Queue table entry, send the XP_CMDShell call to the bat file with parameters Bat file contains Curl call with parameters inserted sending output to logs. Works well.

Again, not perfect, but for a tight timeline, and a system used short term, and that can be closely monitored to react to connectivity and unforeseen issues, it worked.

Hope that helps someone struggling with limited API info get a solution going quickly.

I didn't apply paging on my gridview and it extends to more than 600 records (with checkbox, buttons, etc.) and the value of 2001 didn't work. You may increase the value, say 10000 and test.

<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="10000" />
</appSettings>

The simplest solution to navigate to another component is( Example navigates to mails component by click on icon):

<MailIcon 
  onClick={ () => { this.props.history.push('/mails') } }
/>

I have try this my new code and it might be helpful to you, it works perfectly in google chromr

hr {
     color: #f00;
     background: #f00; 
     width: 75%; 
     height: 5px;
}

Here's a cross-post to a solution to the same problem. More robust than reserved delimiters - includes escaping and nested arrays, and understands NULLs and empty arrays.

C# & T-SQL string[] Pack/Unpack utility functions

You can then join to the table-valued function.

You could use String.prototype.indexOf to accomplish that. Try something like this:

$('.type').keyup(function() {_x000D_
  var v = $(this).val();_x000D_
  if (v.indexOf('> <') !== -1) {_x000D_
    console.log('contains > <');_x000D_
  }_x000D_
  console.log(v);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<textarea class="type"></textarea>

Update

Modern browsers also have a String.prototype.includes method.

This code is based on the most voted question but I might be easier to use

public enum OS {

    WINDOWS,
    MAC,
    LINUX,
    ANDROID,
    IPHONE,
    UNKNOWN;

    public static OS valueOf(HttpServletRequest request) {

        final String userAgent = request.getHeader("User-Agent");
        final OS toReturn;

        if (userAgent == null || userAgent.isEmpty()) {
            toReturn = UNKNOWN;
        } else if (userAgent.toLowerCase().contains("windows")) {
            toReturn = WINDOWS;
        } else if (userAgent.toLowerCase().contains("mac")) {
            toReturn = MAC;
        } else if (userAgent.toLowerCase().contains("x11")) {
            toReturn = LINUX;
        } else if (userAgent.toLowerCase().contains("android")) {
            toReturn = ANDROID;
        } else if (userAgent.toLowerCase().contains("iphone")) {
            toReturn = IPHONE;
        } else {
            toReturn = UNKNOWN;
        }

        return toReturn;
    }

}

A web app can request access to a sandboxed file system by calling window.requestFileSystem(). Works in Chrome.

window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
var fs = null;

window.requestFileSystem(window.TEMPORARY, 1024 * 1024, function (filesystem) {
    fs = filesystem;
}, errorHandler);

fs.root.getFile('Hello.txt', {
    create: true
}, null, errorHandler);

function errorHandler(e) {
  var msg = '';

  switch (e.code) {
    case FileError.QUOTA_EXCEEDED_ERR:
      msg = 'QUOTA_EXCEEDED_ERR';
      break;
    case FileError.NOT_FOUND_ERR:
      msg = 'NOT_FOUND_ERR';
      break;
    case FileError.SECURITY_ERR:
      msg = 'SECURITY_ERR';
      break;
    case FileError.INVALID_MODIFICATION_ERR:
      msg = 'INVALID_MODIFICATION_ERR';
      break;
    case FileError.INVALID_STATE_ERR:
      msg = 'INVALID_STATE_ERR';
      break;
    default:
      msg = 'Unknown Error';
      break;
  };

  console.log('Error: ' + msg);
}

About the most compact way to do this is:

Double array[] = { 1.0, 2.0, 3.0};
List<Double> list = Arrays.asList(array);

 <button onClick="abrirOpen()">Open Dialog</button>

<script type="text/javascript">
var $dialogo = $("<div></div>").html("Aqui tu contenido(here your content)").dialog({

To make more than one element fade in/out sequentially such as 5 elements fade each 4s,

1- make unique animation for each element with animation-duration equal to [ 4s (duration for each element) * 5 (number of elements) ] = 20s

animation-name: anim1 , anim2, anim3 ... 
animation-duration : 20s, 20s, 20s ... 

2- get animation keyframe for each element.

100% (keyframes percentage) / 5 (elements) = 20% (frame for each element)

3- define starting and ending point for each animation:

each animation has 20% frame length and @keyframes percentage always starts from 0%, so first animation will start from 0% and end in his frame(20%), and each next animation will starts from previous animation ending point and end when it reach his frame (+20% ),

@keyframes animation1 { 0% {}, 20% {}}
@keyframes animation2 { 20% {}, 40% {}}
@keyframes animation3 { 40% {}, 60% {}}
and so on

now we need to make each animation fade in from 0 to 1 opacity and fade out from 1 to 0,

so we will add another 2 points (steps) for each animation after starting and before ending point to handle the full opacity(1)

If it is not your build tools, check your strings, styles, attrs, ... XML files and ensure they are correct. For example a string with an empty name-attribute

<string name="">Test"</string>

or a previously undefined attr without a format specified (attrs.xml):

<declare-styleable name="MediaGridView">
    <attr name="allowVideo"/>
</declare-styleable>

I implemented something similar with Horizontal Variable ListView The only drawback is, it works only with Android 2.3 and later.

Using this library is as simple as implementing a ListView with a corresponding Adapter. The library also provides an example

The best solution is just not to use anonymous classes.

public class Test
{
    class DummyInterfaceImplementor : IDummyInterface
    {
        public string A { get; set; }
        public string B { get; set; }
    }

    public void WillThisWork()
    {
        var source = new DummySource[0];
        var values = from value in source
                     select new DummyInterfaceImplementor()
                     {
                         A = value.A,
                         B = value.C + "_" + value.D
                     };

        DoSomethingWithDummyInterface(values.Cast<IDummyInterface>());

    }

    public void DoSomethingWithDummyInterface(IEnumerable<IDummyInterface> values)
    {
        foreach (var value in values)
        {
            Console.WriteLine("A = '{0}', B = '{1}'", value.A, value.B);
        }
    }
}

Note that you need to cast the result of the query to the type of the interface. There might be a better way to do it, but I couldn't find it.

One of the best explanations I have read comes from the great book Code Complete, which I now quote:

A heuristic is a technique that helps you look for an answer. Its results are subject to chance because a heuristic tells you only how to look, not what to find. It doesn’t tell you how to get directly from point A to point B; it might not even know where point A and point B are. In effect, a heuristic is an algorithm in a clown suit. It’s less predict- able, it’s more fun, and it comes without a 30-day, money-back guarantee.

Here is an algorithm for driving to someone’s house: Take Highway 167 south to Puy-allup. Take the South Hill Mall exit and drive 4.5 miles up the hill. Turn right at the light by the grocery store, and then take the first left. Turn into the driveway of the large tan house on the left, at 714 North Cedar.

Here’s a heuristic for getting to someone’s house: Find the last letter we mailed you. Drive to the town in the return address. When you get to town, ask someone where our house is. Everyone knows us—someone will be glad to help you. If you can’t find anyone, call us from a public phone, and we’ll come get you.

The difference between an algorithm and a heuristic is subtle, and the two terms over-lap somewhat. For the purposes of this book, the main difference between the two is the level of indirection from the solution. An algorithm gives you the instructions directly. A heuristic tells you how to discover the instructions for yourself, or at least where to look for them.

You can find online tools that use a dictionary to retrieve the original message.

In some cases, the dictionary method might just be useless:

• if the message is hashed using a SALT message
  
• if the message is hash more than once
  

For example, here is one MD5 decrypter online tool.

This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)

turning it back to 1.0.7 solved the problem instantly.

have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.

anyway, this problem is fixed when using AngularJS vs 1.0.7.

$ bash --init-file <(echo 'some_command')
$ bash --rcfile <(echo 'some_command')

In case you can't or don't want to use process substitution:

$ cat script
some_command
$ bash --init-file script

Another way:

$ bash -c 'some_command; exec bash'
$ sh -c 'some_command; exec sh'

sh-only way (dash, busybox):

$ ENV=script sh

For people getting the windows store window when writing python in the console, all you have to do is go to configuration -> Manage app execution aliases and disable the toggles that say python.

then, add the following folders to the PATH.

Peter's Regex doesn't look right to me for many reasons. It allows all kinds of special characters in the domain name and doesn't test for much.

Frankie's function looks good to me and you can build a good regex from the components if you don't want a function, like so:

^(http://|https://)(([a-z0-9]([-a-z0-9]*[a-z0-9]+)?){1,63}\.)+[a-z]{2,6}

Untested but I think that should work.

Also, Owen's answer doesn't look 100% either. I took the domain part of the regex and tested it on a Regex tester tool http://erik.eae.net/playground/regexp/regexp.html

I put the following line:

(\S*?\.\S*?)

in the "regexp" section and the following line:

-hello.com

under the "sample text" section.

The result allowed the minus character through. Because \S means any non-space character.

Note the regex from Frankie handles the minus because it has this part for the first character:

[a-z0-9]

Which won't allow the minus or any other special character.

If you $ is defined then You can iterate

var data={"id" : 1, "second" : "abcd"};
$.each(data, function() {
  var key = Object.keys(this)[0];
  var value = this[key];
  //do something with value;
}); 

You can access it by following way If you know the values of keys

data.id

or

data["id"]

After adding a resource folder try this :

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("test.png");

try {
    image = ImageIO.read(input);
} catch (IOException e) {
    e.printStackTrace();
}

Ok, I'll take a stab at this. If you want to work with PHP, you will need to install and configure both PHP and a webserver on your machine. This article might get you started: PHP Manual: Installation on Windows systems

Once you have your environment setup, you can start working with webforms. Directly From the article: Processing form data with PHP:

For this example you will need to create two pages. On the first page we will create a simple HTML form to collect some data. Here is an example:

<html>   
<head>
 <title>Test Page</title>
</head>   
<body>   
    <h2>Data Collection</h2><p>
    <form action="process.php" method="post">  
        <table>
            <tr>
                <td>Name:</td>
                <td><input type="text" name="Name"/></td>
            </tr>   
            <tr>
                <td>Age:</td>
                <td><input type="text" name="Age"/></td>
            </tr>   
            <tr>
                <td colspan="2" align="center">
                <input type="submit"/>
                </td>
            </tr>
        </table>
    </form>
</body>
</html>

This page will send the Name and Age data to the page process.php. Now lets create process.php to use the data from the HTML form we made:

<?php   
    print "Your name is ". $Name;   
    print "<br />";   
    print "You are ". $Age . " years old";   
    print "<br />";   $old = 25 + $Age;
    print "In 25 years you will be " . $old . " years old";   
?>

As you may be aware, if you leave out the method="post" part of the form, the URL with show the data. For example if your name is Bill Jones and you are 35 years old, our process.php page will display as http://yoursite.com/process.php?Name=Bill+Jones&Age=35 If you want, you can manually change the URL in this way and the output will change accordingly.

Additional JavaScript Example

This single file example takes the html from your question and ties the onSubmit event of the form to a JavaScript function that pulls the values of the 2 textboxes and displays them in an alert box.

Note: document.getElementById("fname").value gets the object with the ID tag that equals fname and then pulls it's value - which in this case is the text in the First Name textbox.

 <html>
    <head>
     <script type="text/javascript">
     function ExampleJS(){
        var jFirst = document.getElementById("fname").value;
        var jLast = document.getElementById("lname").value;
        alert("Your name is: " + jFirst + " " + jLast);
     }
     </script>

    </head>
    <body>
        <FORM NAME="myform" onSubmit="JavaScript:ExampleJS()">

             First name: <input type="text" id="fname" name="firstname" /><br />
             Last name:  <input type="text" id="lname" name="lastname" /><br />
            <input name="Submit"  type="submit" value="Update" />
        </FORM>
    </body>
</html>

I would like to give example rather than the formal definition.

var originalObject = { 
    a : 1, 
    b : 2, 
    c : 3,
};

This code shows a shallow copy:

var copyObject1 = originalObject;

console.log(copyObject1.a);         // it will print 1 
console.log(originalObject.a);       // it will also print 1 
copyObject1.a = 4; 
console.log(copyObject1.a);           //now it will print 4 
console.log(originalObject.a);       // now it will also print 4

var copyObject2 = Object.assign({}, originalObject);

console.log(copyObject2.a);        // it will print 1 
console.log(originalObject.a);      // it will also print 1 
copyObject2.a = 4; 
console.log(copyObject2.a);        // now it will print 4 
console.log(originalObject.a);      // now it will print 1

This code shows a deep copy:

var copyObject2 = Object.assign({}, originalObject);

console.log(copyObject2.a);        // it will print 1 
console.log(originalObject.a);      // it will also print 1 
copyObject2.a = 4; 
console.log(copyObject2.a);        // now it will print 4 
console.log(originalObject.a);      // !! now it will print 1 !!

Just do:

$object = new stdClass();
$object->name = "My name";
$myArray[] = $object;

You need to create the object first (the new line) and then push it onto the end of the array (the [] line).

You can also do this:

$myArray[] = (object) ['name' => 'My name'];

However I would argue that's not as readable, even if it is more succinct.

for example you have this pdo statement :

$query="insert into tblTest (field1, field2, field3)
values (:val1, :val2, :val3)";
$res=$db->prepare($query);
$res->execute(array(
  ':val1'=>$val1,
  ':val2'=>$val2,
  ':val3'=>$val3,
));

now you can get the executed query by defining an array like this :

$assoc=array(
  ':val1'=>$val1,
  ':val2'=>$val2,
  ':val3'=>$val3,
);
$exQuery=str_replace(array_keys($assoc), array_values($assoc), $query);
echo $exQuery;

You can do

[5, 10].min

or

[4, 7].max

They come from the Enumerable module, so anything that includes Enumerable will have those methods available.

v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.

@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].

[4, 5, 7, 10].minmax
=> [4, 10]

If the row contains some leading (or trailing) th tags before the td you should use the :first-of-type and the :last-of-type selectors. Otherwise the first td won't be selected if it's not the first element of the row.

This gives:

td:first-of-type, td:last-of-type {
    /* styles */
}

First, you need to obtain the public certificate from the server you're trying to connect to. That can be done in a variety of ways, such as contacting the server admin and asking for it, using OpenSSL to download it, or, since this appears to be an HTTP server, connecting to it with any browser, viewing the page's security info, and saving a copy of the certificate. (Google should be able to tell you exactly what to do for your specific browser.)

Now that you have the certificate saved in a file, you need to add it to your JVM's trust store. At $JAVA_HOME/jre/lib/security/ for JREs or $JAVA_HOME/lib/security for JDKs, there's a file named cacerts, which comes with Java and contains the public certificates of the well-known Certifying Authorities. To import the new cert, run keytool as a user who has permission to write to cacerts:

keytool -import -file <the cert file> -alias <some meaningful name> -keystore <path to cacerts file>

It will most likely ask you for a password. The default password as shipped with Java is changeit. Almost nobody changes it. After you complete these relatively simple steps, you'll be communicating securely and with the assurance that you're talking to the right server and only the right server (as long as they don't lose their private key).

I think you should understand what delayed expansion is. The existing answers don't explain it (sufficiently) IMHO.

Typing SET /? explains the thing reasonably well:

Delayed environment variable expansion is useful for getting around the limitations of the current expansion which happens when a line of text is read, not when it is executed. The following example demonstrates the problem with immediate variable expansion:

set VAR=before
if "%VAR%" == "before" (
    set VAR=after
    if "%VAR%" == "after" @echo If you see this, it worked
)

would never display the message, since the %VAR% in BOTH IF statements is substituted when the first IF statement is read, since it logically includes the body of the IF, which is a compound statement. So the IF inside the compound statement is really comparing "before" with "after" which will never be equal. Similarly, the following example will not work as expected:

set LIST=
for %i in (*) do set LIST=%LIST% %i
echo %LIST%

in that it will NOT build up a list of files in the current directory, but instead will just set the LIST variable to the last file found. Again, this is because the %LIST% is expanded just once when the FOR statement is read, and at that time the LIST variable is empty. So the actual FOR loop we are executing is:

for %i in (*) do set LIST= %i

which just keeps setting LIST to the last file found.

Delayed environment variable expansion allows you to use a different character (the exclamation mark) to expand environment variables at execution time. If delayed variable expansion is enabled, the above examples could be written as follows to work as intended:

set VAR=before
if "%VAR%" == "before" (
    set VAR=after
    if "!VAR!" == "after" @echo If you see this, it worked
)

set LIST=
for %i in (*) do set LIST=!LIST! %i
echo %LIST%

Another example is this batch file:

@echo off
setlocal enabledelayedexpansion
set b=z1
for %%a in (x1 y1) do (
 set b=%%a
 echo !b:1=2!
)

This prints x2 and y2: every 1 gets replaced by a 2.

Without setlocal enabledelayedexpansion, exclamation marks are just that, so it will echo !b:1=2! twice.

Because normal environment variables are expanded when a (block) statement is read, expanding %b:1=2% uses the value b has before the loop: z2 (but y2 when not set).

In order to encode + value using JavaScript, you can use encodeURIComponent function.

Example:

var url = "+11";
var encoded_url = encodeURIComponent(url);
console.log(encoded_url)

A char consists of a single character and should be specified in single quotes. It can contain an alphabetic, numerical or even special character. below are a few examples:

char a = '4';
char b = '$';
char c = 'B';

A String defines a line can be used which is specified in double quotes. Below are a few examples:

String a = "Hello World";
String b = "1234";
String c = "%%";

tl;dr

Instant.now()                           // Capture the current moment in UTC.
.atZone( ZoneId.systemDefault() )       // Adjust into the JVM's current default time zone. Same moment, different wall-clock time. Produces a `ZonedDateTime` object.
.toInstant()                            // Extract a `Instant` (always in UTC) object from the `ZonedDateTime` object.
.atZone( ZoneId.of( "Europe/Paris" ) )  // Adjust the `Instant` into a specific time zone. Renders a `ZonedDateTime` object. Same moment, different wall-clock time.
.toInstant()                            // And back to UTC again.

java.time

The modern approach uses the java.time classes that supplanted the troublesome old legacy date-time classes (Date, Calendar, etc.).

Your use of the word "local" contradicts the usage in the java.time class. In java.time, "local" means any locality or all localities, but not any one particular locality. The java.time classes with names starting with "Local…" all lack any concept of time zone or offset-from-UTC. So they do not represent a specific moment, they are not a point on the timeline, whereas your Question is all about moments, points on the timeline viewed through various wall-clock times.

Get the current system time (local time)

If you want to capture the current moment in UTC, use Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = Instant.now() ;  // Capture the current moment in UTC.

Adjust into a time zone by applying a ZoneId to get a ZonedDateTime. Same moment, same point on the timeline, different wall-clock time.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;  // Same moment, different wall-clock time.

As a shortcut, you can skip the usage of Instant to get a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ) ;

Convert Local time to UTC // Works Fine Till here

You can adjust from the zoned date-time to UTC by extracting an Instant from a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ) ;
Instant instant = zdt.toInstant() ;

Reverse the UTC time, back to local time.

As shown above, apply a ZoneId to adjust the same moment into another wall-clock time used by the people of a certain region (a time zone).

Instant instant = Instant.now() ;  // Capture current moment in UTC.

ZoneId zDefault = ZoneId.systemDefault() ;  // The JVM's current default time zone.
ZonedDateTime zdtDefault = instant.atZone( zDefault ) ;

ZoneId zTunis = ZoneId.of( "Africa/Tunis" ) ;  // The JVM's current default time zone.
ZonedDateTime zdtTunis = instant.atZone( zTunis ) ;

ZoneId zAuckland = ZoneId.of( "Pacific/Auckland" ) ;  // The JVM's current default time zone.
ZonedDateTime zdtAuckland = instant.atZone( zAuckland ) ;

Going back to UTC from a zoned date-time, call ZonedDateTime::toInstant. Think of it conceptually as: ZonedDateTime = Instant + ZoneId.

Instant instant = zdtAuckland.toInstant() ;

All of these objects, the Instant and the three ZonedDateTime objects all represent the very same simultaneous moment, the same point in history.

Followed 3 different approaches (listed below) but all the 3 approaches retains the time in UTC only.

Forget about trying to fix code using those awful Date, Calendar, and GregorianCalendar classes. They are a wretched mess of bad design and flaws. You need never touch them again. If you must interface with old code not yet updated to java.time, you can convert back-and-forth via new conversion methods added to the old classes.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

A sample using C# is here.

public static void Main()
{
    Console.WriteLine("Hello World " + LevenshteinDistance("Hello","World"));
    Console.WriteLine("Choice A " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED COW JUMPED OVER THE GREEN CHICKEN"));
    Console.WriteLine("Choice B " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED COW JUMPED OVER THE RED COW"));
    Console.WriteLine("Choice C " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED FOX JUMPED OVER THE BROWN COW"));
}

public static float LevenshteinDistance(string a, string b)
{
    var rowLen = a.Length;
    var colLen = b.Length;
    var maxLen = Math.Max(rowLen, colLen);

    // Step 1
    if (rowLen == 0 || colLen == 0)
    {
        return maxLen;
    }

    /// Create the two vectors
    var v0 = new int[rowLen + 1];
    var v1 = new int[rowLen + 1];

    /// Step 2
    /// Initialize the first vector
    for (var i = 1; i <= rowLen; i++)
    {
        v0[i] = i;
    }

    // Step 3
    /// For each column
    for (var j = 1; j <= colLen; j++)
    {
        /// Set the 0'th element to the column number
        v1[0] = j;

        // Step 4
        /// For each row
        for (var i = 1; i <= rowLen; i++)
        {
            // Step 5
            var cost = (a[i - 1] == b[j - 1]) ? 0 : 1;

            // Step 6
            /// Find minimum
            v1[i] = Math.Min(v0[i] + 1, Math.Min(v1[i - 1] + 1, v0[i - 1] + cost));
        }

        /// Swap the vectors
        var vTmp = v0;
        v0 = v1;
        v1 = vTmp;
    }

    // Step 7
    /// The vectors were swapped one last time at the end of the last loop,
    /// that is why the result is now in v0 rather than in v1
    return v0[rowLen];
}

The output is:

Hello World 4
Choice A 15
Choice B 6
Choice C 8

I'm exceptionally new to VBScript, so this may not be considered best practice or there may be a reason it shouldn't be done this that way I'm not yet aware of, but this is the solution I came up with to trim down the amount of error logging code in my main code block.

Dim oConn, connStr
Set oConn = Server.CreateObject("ADODB.Connection")
connStr = "Provider=SQLOLEDB;Server=XX;UID=XX;PWD=XX;Databse=XX"

ON ERROR RESUME NEXT

oConn.Open connStr
If err.Number <> 0 Then : showError() : End If


Sub ShowError()

    'You could write the error details to the console...
    errDetail = "<script>" & _
    "console.log('Description: " & err.Description & "');" & _
    "console.log('Error number: " & err.Number & "');" & _
    "console.log('Error source: " & err.Source & "');" & _
    "</script>"

    Response.Write(errDetail)       

    '...you could display the error info directly in the page...
    Response.Write("Error Description: " & err.Description)
    Response.Write("Error Source: " & err.Source)
    Response.Write("Error Number: " & err.Number)

    '...or you could execute additional code when an error is thrown...
    'Insert error handling code here

    err.clear
End Sub

Simplest solution I have seen

Here is a detail for int.Parse and Convert.ToInt32: Say, you have a char array, char[] a=['1','2','3','4'] and want to convert each element into an integer. The Convert.ToInt32(a[0]) will give you a number of 49. It treats it as ASCII code The int.Parse(a[0]) will give you the right output which is 1

If you have a string array string[] b=['1','2','3','4'], then Convert.ToInt32 and int.Parse will have no difference in output. Both return the right integer.

I've used this function several times:

public static bool IsNumeric(object Expression)
{
    double retNum;

    bool isNum = Double.TryParse(Convert.ToString(Expression), System.Globalization.NumberStyles.Any, System.Globalization.NumberFormatInfo.InvariantInfo, out retNum);
    return isNum;
}

But you can also use;

bool b1 = Microsoft.VisualBasic.Information.IsNumeric("1"); //true
bool b2 = Microsoft.VisualBasic.Information.IsNumeric("1aa"); // false

Rather than placing an extra scanner.nextLine() each time you want to read something, since it seems you want to accept each input on a new line, you might want to instead changing the delimiter to actually match only newlines (instead of any whitespace, as is the default)

import java.util.Scanner;

class ScannerTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        scanner.useDelimiter("\\n");

        System.out.print("Enter an index: ");
        int index = scanner.nextInt();

        System.out.print("Enter a sentence: ");
        String sentence = scanner.next();

        System.out.println("\nYour sentence: " + sentence);
        System.out.println("Your index: " + index);
    }
}

Thus, to read a line of input, you only need scanner.next() that has the same behavior delimiter-wise of next{Int, Double, ...}

The difference with the "nextLine() every time" approach, is that the latter will accept, as an index also <space>3, 3<space> and 3<space>whatever while the former only accepts 3 on a line on its own

You can use .filter() with boolean operators ie &&:

     var find = my_array.filter(function(result) {
       return result.param1 === "srting1" && result.param2 === 'string2';
     });
     
     return find[0];

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

These look the same as their real counterparts in Safari, Chrome, and Firefox. They degrade gracefully and look OK in Opera and IE9, too.

Your C# action "Save" doesn't execute because your AJAX url is pointing to "/Home/SaveDetailedInfo" and not "/Home/Save".

To call another action from within an action you can maybe try this solution: link

Here's another better solution : link

[HttpPost]
public ActionResult SaveDetailedInfo(Option[] Options)
{
    return Json(new { status = "Success", message = "Success" });
}

[HttpPost]
public ActionResult Save()
{ 
    return RedirectToAction("SaveDetailedInfo", Options);
}

AJAX:

Initial ajax call url: "/Home/Save"
on success callback: 
   make new ajax url: "/Home/SaveDetailedInfo"

The double arrow operator, =>, is used as an access mechanism for arrays. This means that what is on the left side of it will have a corresponding value of what is on the right side of it in array context. This can be used to set values of any acceptable type into a corresponding index of an array. The index can be associative (string based) or numeric.

$myArray = array(
    0 => 'Big',
    1 => 'Small',
    2 => 'Up',
    3 => 'Down'
);

The object operator, ->, is used in object scope to access methods and properties of an object. It’s meaning is to say that what is on the right of the operator is a member of the object instantiated into the variable on the left side of the operator. Instantiated is the key term here.

// Create a new instance of MyObject into $obj
$obj = new MyObject();
// Set a property in the $obj object called thisProperty
$obj->thisProperty = 'Fred';
// Call a method of the $obj object named getProperty
$obj->getProperty();

If you return "false" from your function it'll stop the event bubbling, so only your first event handler will get triggered (ie. your anchor will not see the click).

$("div.clickable").click(
function()
{
    window.location = $(this).attr("url");
    return false;
});

See event.preventDefault() vs. return false for details on return false vs. preventDefault.

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

So if you are using Moq, and want to mock the result of an Extension method, then you can use SetupReturnsDefault<ReturnTypeOfExtensionMethod>(new ConcreteInstanceToReturn()) on the instance of the mock class that has the extension method you are trying to mock.

It is not perfect, but for unit testing purposes it works well.

For using DOSBox with SDL, you will need to set or change the following:

[sdl]
windowresolution=1280x960
output=opengl

Here is three options to put those settings:

1. Edit user's default configuration, for example, using vi:

   $ dosbox -printconf
   /home/USERNAME/.dosbox/dosbox-0.74.conf
   $ vi "$(dosbox -printconf)"
   $ dosbox
   

2. For temporary resize, create a new configuration with the three lines above, say newsize.conf:

   $ dosbox -conf newsize.conf
   

   You can use -conf to load multiple configuration and/or with -userconf for default configuration, for example:

   $ dosbox -userconf -conf newsize.conf 
   [snip]
   ---
   CONFIG:Loading primary settings from config file /home/USERNAME/.dosbox/dosbox-0.74.conf
   CONFIG:Loading additional settings from config file newsize.conf
   [snip]
   

3. Create a dosbox.conf under current directory, DOSBox loads it as default.

DOSBox should start up and resize to 1280x960 in this case.

Note that you probably would not get any size you desired, for instance, I set 1280x720 and I got 1152x720.

To install the 3rd party jar which is not in maven repository use maven-install-plugin.

Below are steps:

1. Download the jar file manually from the source (website)
2. Create a folder and place your jar file in it
3. Run the below command to install the 3rd party jar in your local maven repository

mvn install:install-file -Dfile= -DgroupId= -DartifactId= -Dversion= -Dpackaging=

Below is the e.g one I used it for simonsite log4j

mvn install:install-file -Dfile=/Users/athanka/git/MyProject/repo/log4j-rolling-appender.jar -DgroupId=uk.org.simonsite -DartifactId=log4j-rolling-appender -Dversion=20150607-2059 -Dpackaging=jar

4. In the pom.xml include the dependency as below

     <dependency> 
           <groupId>uk.org.simonsite</groupId>
           <artifactId>log4j-rolling-appender</artifactId>
           <version>20150607-2059</version> 
     </dependency>
   

5. Run the mvn clean install command to create your packaging

Below is the reference link:

https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html

The server.contextPath or server.context-path works if

in pom.xml

1. packing should be war not jar

2. Add following dependencies

   <dependency>
       <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <!-- Tomcat/TC server -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>
   

   In eclipse, right click on project --> Run as --> Spring Boot App.

Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this

String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");

and now you have a String which can be parsed back to java.lang.Number, for example,

long veryLongNumber = Long.parseLong(intStr);

Or you can use the java 8 streams, if you hate regex,

String strOfInts = Arrays
            .stream(intArray)
            .mapToObj(String::valueOf)
            .reduce((a, b) -> a.concat(",").concat(b))
            .get();

If you want to pass just the index.php ( no other php file will be passed to fastcgi ) to fastcgi in case you have routes like this in a framework like codeigniter

$route["/download.php"] = "controller/method";

One better check that can be done if you get such error while accessing a file is to use the file.exists("file_path/file_name") function. This function will return TRUE if the file is existing and accessible, else False.

DATEADD (datepart , number , date )

declare @num_hours int; 
    set @num_hours = 5; 

select dateadd(HOUR, @num_hours, getdate()) as time_added, 
       getdate() as curr_date  

Personally, I would prefer

<IF>
  <TIME from="5pm" to="9pm" />
  <THEN>
    <!-- action -->
  </THEN>
  <ELSE>
    <!-- action -->
  </ELSE>
</IF>

In this way you don't need an id attribute to tie together the IF, THEN, ELSE tags

Python 2

What you're looking for is urllib.quote_plus:

>>> urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')
'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'

Python 3

In Python 3, the urllib package has been broken into smaller components. You'll use urllib.parse.quote_plus (note the parse child module)

import urllib.parse
urllib.parse.quote_plus(...)

The map method takes an enumerable object and a block, and runs the block for each element, outputting each returned value from the block (the original object is unchanged unless you use map!):

[1, 2, 3].map { |n| n * n } #=> [1, 4, 9]

Array and Range are enumerable types. map with a block returns an Array. map! mutates the original array.

Where is this helpful, and what is the difference between map! and each? Here is an example:

names = ['danil', 'edmund']

# here we map one array to another, convert each element by some rule
names.map! {|name| name.capitalize } # now names contains ['Danil', 'Edmund']

names.each { |name| puts name + ' is a programmer' } # here we just do something with each element

The output:

Danil is a programmer
Edmund is a programmer

I try to explain this problem step by step in following example.

0) Question

I try to ask you like this :

i want to open page like facebook profile www.facebook.com/kaila.piyush

it get id from url and parse it to profile.php file and return featch data from database and show user to his profile

normally when we develope any website its link look like www.website.com/profile.php?id=username example.com/weblog/index.php?y=2000&m=11&d=23&id=5678

now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink

http://example.com/profile/userid (get a profile by the ID) 
http://example.com/profile/username (get a profile by the username) 
http://example.com/myprofile (get the profile of the currently logged-in user)

1) .htaccess

Create a .htaccess file in the root folder or update the existing one :

Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
#  Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php

What does that do ?

If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.

2) index.php

Now, we want to know what action to trigger, so we need to read the URL :

In index.php :

// index.php    

// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);

for ($i= 0; $i < sizeof($scriptName); $i++)
{
    if ($requestURI[$i] == $scriptName[$i])
    {
        unset($requestURI[$i]);
    }
}

$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :

$command = array(
    [0] => 'profile',
    [1] => 19837,
    [2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :

// index.php

require_once("profile.php"); // We need this file
switch($command[0])
{
    case ‘profile’ :
        // We run the profile function from the profile.php file.
        profile($command([1]);
        break;
    case ‘myprofile’ :
        // We run the myProfile function from the profile.php file.
        myProfile();
        break;
    default:
        // Wrong page ! You could also redirect to your custom 404 page.
        echo "404 Error : wrong page.";
        break;
}

2) profile.php

Now in the profile.php file, we should have something like this :

// profile.php

function profile($chars)
{
    // We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)

    if (is_int($chars)) {
        $id = $chars;
        // Do the SQL to get the $user from his ID
        // ........
    } else {
        $username = mysqli_real_escape_string($char);
        // Do the SQL to get the $user from his username
        // ...........
    }

    // Render your view with the $user variable
    // .........
}

function myProfile()
{
    // Get the currently logged-in user ID from the session :
    $id = ....

    // Run the above function :
    profile($id);
}

For me, with Homebrew 1.6.7, the following worked:

brew upgrade git

So, after update I had the same issue. I was using PEM key_file without extension and simply adding .pem fixed my issue. Now the file is key_file.pem.

It's a C trigraph. ??! is |, so ??!??! is the operator ||

Using this HTML:

<div id="myElement" style="position: absolute">This stays at the top</div>

This is the javascript you want to use. It attaches an event to the window's scroll and moves the element down as far as you've scrolled.

$(window).scroll(function() {
    $('#myElement').css('top', $(this).scrollTop() + "px");
});

As pointed out in the comments below, it's not recommended to attach events to the scroll event - as the user scrolls, it fires A LOT, and can cause performance issues. Consider using it with Ben Alman's debounce/throttle plugin to reduce overhead.

summation and your other functions are defined after they're used in main, and so the compiler has made a guess about it's signature; in other words, an implicit declaration has been assumed.

You should declare the function before it's used and get rid of the warning. In the C99 specification, this is an error.

Either move the function bodies before main, or include method signatures before main, e.g.:

#include <stdio.h>

int summation(int *, int *, int *);

int main()
{
    // ...

If it's in a class, you can use getattr:

class MyClass(object):
    def install(self):
          print "In install"

method_name = 'install' # set by the command line options
my_cls = MyClass()

method = None
try:
    method = getattr(my_cls, method_name)
except AttributeError:
    raise NotImplementedError("Class `{}` does not implement `{}`".format(my_cls.__class__.__name__, method_name))

method()

or if it's a function:

def install():
       print "In install"

method_name = 'install' # set by the command line options
possibles = globals().copy()
possibles.update(locals())
method = possibles.get(method_name)
if not method:
     raise NotImplementedError("Method %s not implemented" % method_name)
method()

If you are using SQL Server 2008 or later

select convert(date, getdate())

Otherwise

select convert(varchar(10), getdate(),120)

in HQL you can use query parameter and set Collection with setParameterList method.

    Query q = session.createQuery("SELECT entity FROM Entity entity WHERE name IN (:names)");
    q.setParameterList("names", names);

sys.maxint is not the largest integer supported by python. It's the largest integer supported by python's regular integer type.

1. Change to folder %PROGRAMFILES%\Git\etc
2. Edit file profile
3. Add to first line HOME="c:\location_were_you_want_gitconfig"
4. Done

Note: The file permissions are usually restricted, so change them accordingly or you won't be able to save your changes.

You could use XDocument:

new XDocument(
    new XElement("root", 
        new XElement("someNode", "someValue")    
    )
)
.Save("foo.xml");

If the file you want to create is very big and cannot fit into memory you might use XmlWriter.

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

I'm late to the party, here is an Excel VBA script I wrote years ago for Australia. It can be easily modified to support other Countries. I've made a GitHub repository of the C# code here. I've hosted it on my site and you can download it here: http://jeremythompson.net/rocks/ParseAddress.xlsm

Strategy

For any country with a PostCode that's numeric or can be matched with a RegEx my strategy works very well:

1. First we detect the First and Surname which are assumed to be the top line. Its easy to skip the name and start with the address by unticking the checkbox (called 'Name is top row' as shown below).

2. Next its safe to expect the Address consisting of the Street and Number come before the Suburb and the St, Pde, Ave, Av, Rd, Cres, loop, etc is a separator.

3. Detecting the Suburb vs the State and even Country can trick the most sophisticated parsers as there can be conflicts. To overcome this I use a PostCode look up based on the fact that after stripping Street and Apartment/Unit numbers as well as the PoBox,Ph,Fax,Mobile etc, only the PostCode number will remain. This is easy to match with a regEx to then look up the suburb(s) and country.

Your National Post Office Service will provide a list of post codes with Suburbs and States free of charge that you can store in an excel sheet, db table, text/json/xml file, etc.

4. Finally, since some Post Codes have multiple Suburbs we check which suburb appears in the Address.

Example

VBA Code

DISCLAIMER, I know this code is not perfect, or even written well however its very easy to convert to any programming language and run in any type of application.The strategy is the answer depending on your country and rules, take this code as an example:

I resolved this issue as I was typing the question. I figured I'd answer my question and leave it here for anyone else who may face this issue when using Xcode 6 beta 4.

To resolve this issue, you need to select each of your custom class objects in Storyboard (this includes any custom views, even the custom view controllers themselves).

Then with those objects selected, open the identity inspector and under "Custom Class" you should see the Module option. Click inside the Module text box, and press enter.

That's it! The current module for all of my custom objects must have been internally incorrectly set somehow in Xcode 6 beta 4. But there was no visual indication of this in the inspector.

Note that if pressing enter inside the Module text box doesn't work, try selecting the arrow to the right and manually select your current module, then clear the text box and press enter. You can also try pressing enter inside the class text box (although this usually is to resolve a different issue).

Here is an image to make things more clear:

Alright I had some issues getting this to work using a self signed cert for testing so I am going to copy my setup that worked for me. If your not using a self signed cert you probably wont have these issues, hopefully!

To start off depending on your browser Firefox or Chrome you may have different issues and I'll explain in a minute.

First the Setup:

Client

// May need to load the client script from a Absolute Path
<script src="https://www.YOURDOMAIN.com/node/node_modules/socket.io-client/dist/socket.io.js"></script>
<script>
var options = {
          rememberUpgrade:true,
          transports: ['websocket'],
          secure:true, 
          rejectUnauthorized: false
              }
var socket = io.connect('https://www.YOURDOMAIN.com:PORT', options);

// Rest of your code here
</script>

Server

var fs = require('fs');

var options = {
  key: fs.readFileSync('/path/to/your/file.pem'),
  cert: fs.readFileSync('/path/to/your/file.crt'),

};
var origins = 'https://www.YOURDOMAIN.com:*';
var app = require('https').createServer(options,function(req,res){

    // Set CORS headers
    res.setHeader('Access-Control-Allow-Origin', 'https://www.YOURDOMAIN.com:*');
    res.setHeader('Access-Control-Request-Method', '*');
    res.setHeader('Access-Control-Allow-Methods', 'OPTIONS, GET');
    res.setHeader('Access-Control-Allow-Headers', '*');
    if ( req.method === 'OPTIONS' || req.method === 'GET' ) {
        res.writeHead(200);
        res.end();
        return;
            }

});

var io = require('socket.io')(app);

app.listen(PORT);

For development the options used on the client side are ok in production you would want the option:

 rejectUnauthorized: false

You would more than likely want set to "true"

Next thing is if its a self signed cert you will need to vist your server in a separate page/tab and accept the cert or import it into your browser.

For Firefox I kept getting the error

MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

The solution for me was to add the following options and accepting the cert in a different page/tab.

{ 
rejectUnauthorized: false
} 

In Chrome I had to open another page and accept the cert but after that everything worked fine with out having to add any options.

Hope this helps.

Thanks for your answers. I didn't understand what type of object "MyTable" was (in your answers) and the following code gave me the error shown below.

DataTable dt = ds.Tables[0];
var name = from r in dt
           where r.ID == 0
           select r.Name;

Could not find an implementation of the query pattern for source type 'System.Data.DataTable'. 'Where' not found

So I continued my googling and found something that does work:

var rowColl = ds.Tables[0].AsEnumerable();
string name = (from r in rowColl
              where r.Field<int>("ID") == 0
              select r.Field<string>("NAME")).First<string>();

What do you think?

For those who prefer using the Task Scheduler, it's possible to schedule a task to run after a restart / shutdown has been initiated by setting the task to run after event 1074 in the System log in the Event Viewer has been logged. However, it's only good for very short task, which will run as long as the system is restarting / shutting down, which is usually only a few seconds.

• From the Task Scheduler:
  

  Begin the task: On an event
  Log: System
  Source: USER32
  EventID: 1074

• From the command prompt:
  

  schtasks /create /tn "taskname" /tr "task file" /sc onevent /ec system /mo *[system/eventid=1074]

Comment: the /ec option is available from Windows Vista and above. (thank you @t2d)

Please note that the task status can be:

The operation being requested was not performed because the user has not logged on to the network. The specified service does not exist. (0x800704DD)

However, it doesn't mean that it didn't run.

If it IS a foreach loop as you have described in the question, using $key => $value is fast and efficient.

This thread has some great tips. However....

@GirishB's answer isn't correct - sorry. Jartender's is best.

Also, every post in here seems to assume you're logging in to the Linux guest as root, except for @tomoguisuru. Yuck! Don't use root, use a separate user account and "sudo" when you need root privileges. Then this user (or any other user who needs the shared folder) should have membership in the vboxsf group, and @tomoguisuru's command is perfect, even terser than what I use.

Forget running mount yourself. Set up the shared folder to auto mount and you'll find the shared folder - it's under /media in my OEL (RH and Centos probably the same). If it's not there, just run "mount" with no arguments and look for the mounted directory of type vboxsf.

PowerShell Core (v6+) now has a Remove-Service cmdlet.

I don't know about plans to back-port it to Windows PowerShell, where it is not available as of v5.1.

Example:

# PowerShell *Core* only (v6+)
Remove-Service someservice

Note that invocation fails if the service doesn't exist, so to only remove it if it currently exists, you could do:

# PowerShell *Core* only (v6+)
$name = 'someservice'
if (Get-Service $name -ErrorAction Ignore) {
  Remove-Service $name
}

Most languages have path parsing functions that will give you this already. If you have the ability, I'd recommend using what comes to you for free out-of-the-box.

Assuming / is the path delimiter...

^(.*/)([^/]*)$

The first group will be whatever the directory/path info is, the second will be the filename. For example:

• /foo/bar/baz.log: "/foo/bar/" is the path, "baz.log" is the file
• foo/bar.log: "foo/" is the path, "bar.log" is the file
• /foo/bar: "/foo/" is the path, "bar" is the file
• /foo/bar/: "/foo/bar/" is the path and there is no file.

In addition to @Malk, I wanted to clear all fields in the popup, except the hidden fields. To do that just use this:

$('.modal').on('hidden.bs.modal', function () {
    $(this)
        .find("input:not([type=hidden]),textarea,select")
        .val('')
        .end()
        .find("input[type=checkbox], input[type=radio]")
        .prop("checked", "")
        .end();
});

This will clear all fields, except the hidden ones.

Task.WaitAll blocks the current thread until everything has completed.

Task.WhenAll returns a task which represents the action of waiting until everything has completed.

That means that from an async method, you can use:

await Task.WhenAll(tasks);

... which means your method will continue when everything's completed, but you won't tie up a thread to just hang around until that time.

 function uploadFile() {
     var fileElement = document.getElementById("fileToUpload");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension == "odx-d"||fileExtension == "odx"||fileExtension == "pdx"||fileExtension == "cmo"||fileExtension == "xml") {
         var fd = new FormData();
        fd.append("fileToUpload", document.getElementById('fileToUpload').files[0]);
        var xhr = new XMLHttpRequest();
        xhr.upload.addEventListener("progress", uploadProgress, false);
        xhr.addEventListener("load", uploadComplete, false);
        xhr.addEventListener("error", uploadFailed, false);
        xhr.addEventListener("abort", uploadCanceled, false);
        xhr.open("POST", "/post_uploadReq");
        xhr.send(fd);
        }
        else {
            alert("You must select a valid odx,pdx,xml or cmo file for upload");
            return false;
        }
       
      }

tried this , works very well

This is a gem:

https://www.digitalocean.com/community/tutorials/an-introduction-to-oauth-2

Very brief summary:

OAuth defines four roles:

1. Resource Owner
2. Client
3. Resource Server
4. Authorization Server

You (Resource Owner) have a mobile phone. You have several different email accounts, but you want all your email accounts in one app, so you don't need to keep switching. So your GMail (Client) asks for access (via Yahoo's Authorization Server) to your Yahoo emails (Resource Server) so you can read both emails on your GMail application.

The reason OAuth exists is because it is unsecure for GMail to store your Yahoo username and password.

It's the ternary form of the if-else operator. The above statement basically reads like this:

if ($add_review) then {
    return FALSE; //$add_review evaluated as True
} else {
    return $arg //$add_review evaluated as False
}

See here for more details on ternary op in PHP: http://www.addedbytes.com/php/ternary-conditionals/

Non-const and const reference binding follow different rules

These are the rules of the C++ language:

• an expression consisting of a literal number (12) is a "rvalue"
• it is not permitted to create a non-const reference with a rvalue: int &ri = 12; is ill-formed
• it is permitted to create a const reference with a rvalue: in this case, an unnamed object is created by the compiler; this object will persist as long as the reference itself exist.

You have to understand that these are C++ rules. They just are.

It is easy to invent a different language, say C++', with slightly different rules. In C++', it would be permitted to create a non-const reference with a rvalue. There is nothing inconsistent or impossible here.

But it would allow some risky code where the programmer might not get what he intended, and C++ designers rightly decided to avoid that risk.

You can also make it work with RelativeLayout. This reduces layout nesting a little bit ;)

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/toolbar" />

    <View
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:layout_below="@id/toolbar"
        android:background="@drawable/toolbar_shadow" />
</RelativeLayout>

I got the very easy solution for this - setting different width for column in style sheet by overriding the both cell and header cell:

Example - setting custom width for 1st and 5th column:

.mat-cell:nth-child(1),
.mat-header-cell:nth-child(1) {
  flex: 0 0 5%;
}
.mat-cell:nth-child(5),
.mat-header-cell:nth-child(5) {
  flex: 0 0 10%;
}

The JWT is stored on browser, so remove the token deleting the cookie at client side

If you need also to invalidate the token from server side before its expiration time, for example account deleted/blocked/suspended, password changed, permissions changed, user logged out by admin, take a look at Invalidating JSON Web Tokens for some commons techniques like creating a blacklist or rotating tokens

My understanding is that this question is better answered over in this post.

But briefly, the answer to the OP with this method is simply:

s1 = pd.merge(df1, df2, how='inner', on=['user_id'])

Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.

Change:

x.length

to:

x.options.length

Link to fiddle

And I agree with Abraham - you might want to use text instead of value

Update
The reason your fiddle didn't work was because you chose the option: "onLoad" instead of: "No wrap - in "

In Swift 4, I had used the locationManager delegate function as defined above ..

func locationManager(manager: CLLocationManager!, 
    didUpdateLocations locations: [AnyObject]!) {

.. but this needed to be changed to ..

func locationManager(_ manager: CLLocationManager,
    didUpdateLocations locations: [CLLocation]) {

This came from .. https://github.com/lotfyahmed/MyLocation/blob/master/MyLocation/ViewController.swift - thanks!

This error is caused by:

Y = Dataset.iloc[:,18].values

Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn't use Y at all, so you can just comment out this line for now.

There are actually people wanting to write with two-way binding, but React does not work in that way.

That's true, there are people who want to write with two-way data binding. And there's nothing fundamentally wrong with React preventing them from doing so. I wouldn't recommend them to use deprecated React mixin for that, though. Because it looks so much better with some third-party packages.

import { LinkedComponent } from 'valuelink'

class Test extends LinkedComponent {
    state = { a : "Hi there! I'm databinding demo!" };

    render(){
        // Bind all state members...
        const { a } = this.linkAll();

        // Then, go ahead. As easy as that.
        return (
             <input type="text" ...a.props />
        )
    }
}

The thing is that the two-way data binding is the design pattern in React. Here's my article with a 5-minute explanation on how it works

You can include the hidden directories by going back a directory and doing:

cd ..
tar czf workspace.tar.gz workspace

Assuming the directory you wanted to gzip was called workspace.

NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:@"First",@"Second", nil];
NSMutableArray *copiedArray = [array mutableCopy];
NSMutableArray *retainedArray = [array retain];

[retainedArray addObject:@"Retained Third"];
[copiedArray addObject:@"Copied Third"];

NSLog(@"array = %@",array);
NSLog(@"Retained Array = %@",retainedArray);
NSLog(@"Copied Array = %@",copiedArray);

array = (
    First,
    Second,
    "Retained Third"
)
Retained Array = (
    First,
    Second,
    "Retained Third"
)
Copied Array = (
    First,
    Second,
    "Copied Third"
)

Solution 1: Log stdout AND stderr concurrently in realtime

A simple solution which logs both stdout AND stderr concurrently, line-by-line in realtime into a log file.

import subprocess as sp
from concurrent.futures import ThreadPoolExecutor


def log_popen_pipe(p, stdfile):

    with open("mylog.txt", "w") as f:

        while p.poll() is None:
            f.write(stdfile.readline())
            f.flush()

        # Write the rest from the buffer
        f.write(stdfile.read())


with sp.Popen(["ls"], stdout=sp.PIPE, stderr=sp.PIPE, text=True) as p:

    with ThreadPoolExecutor(2) as pool:
        r1 = pool.submit(log_popen_pipe, p, p.stdout)
        r2 = pool.submit(log_popen_pipe, p, p.stderr)
        r1.result()
        r2.result()

Solution 2: A function read_popen_pipes() that allows you to iterate over both pipes (stdout/stderr), concurrently in realtime

import subprocess as sp
from queue import Queue, Empty
from concurrent.futures import ThreadPoolExecutor


def enqueue_output(file, queue):
    for line in iter(file.readline, ''):
        queue.put(line)
    file.close()


def read_popen_pipes(p):

    with ThreadPoolExecutor(2) as pool:
        q_stdout, q_stderr = Queue(), Queue()

        pool.submit(enqueue_output, p.stdout, q_stdout)
        pool.submit(enqueue_output, p.stderr, q_stderr)

        while True:

            if p.poll() is not None and q_stdout.empty() and q_stderr.empty():
                break

            out_line = err_line = ''

            try:
                out_line = q_stdout.get_nowait()
                err_line = q_stderr.get_nowait()
            except Empty:
                pass

            yield (out_line, err_line)

# The function in use:

with sp.Popen(["ls"], stdout=sp.PIPE, stderr=sp.PIPE, text=True) as p:

    for out_line, err_line in read_popen_pipes(p):
        print(out_line, end='')
        print(err_line, end='')

    p.poll()

I had this error because I was providing a string of arguments to subprocess.call instead of an array of arguments. To prevent this, use shlex.split:

import shlex, subprocess
command_line = "ls -a"
args = shlex.split(command_line)
p = subprocess.Popen(args)

the worked proposition for me is __call__ on class who create list of little numbers:

import itertools
    
class SmallNumbers:
    def __init__(self, how_much):
        self.how_much = int(how_much)
        self.work_list = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
        self.generated_list = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
        start = 10
        end = 100
        for cmb in range(2, len(str(self.how_much)) + 1):
            self.ListOfCombinations(is_upper_then=start, is_under_then=end, combinations=cmb)
            start *= 10
            end *= 10

    def __call__(self, number, *args, **kwargs):
        return self.generated_list[number]

    def ListOfCombinations(self, is_upper_then, is_under_then, combinations):
        multi_work_list = eval(str('self.work_list,') * combinations)
        nbr = 0
        for subset in itertools.product(*multi_work_list):
            if is_upper_then <= nbr < is_under_then:
                self.generated_list.append(''.join(subset))
                if self.how_much == nbr:
                    break
            nbr += 1

and to run it:

if __name__ == '__main__':
        sm = SmallNumbers(56)
        print(sm.generated_list)
        print(sm.generated_list[34], sm.generated_list[27], sm.generated_list[10])
        print('The Best', sm(15), sm(55), sm(49), sm(0))

result

['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50', '51', '52', '53', '54', '55', '56']

You can use substr:

echo substr('a,b,c,d,e,', 0, -1);
# => 'a,b,c,d,e'

Just Run MySQL Server Installer and Reconfigure the My SQL Server...This worked for me.

Lots of choices here, but figured I'd toss mine on the heap. It is perl based, only targets variables of the form ${...}, takes the file to process as an argument and outputs the converted file on stdout:

use Env;
Env::import();

while(<>) { $_ =~ s/(\${\w+})/$1/eeg; $text .= $_; }

print "$text";

Of course I'm not really a perl person, so there could easily be a fatal flaw (works for me though).

Its not possible as you are expecting. But you can do something like this. Pass the your java script value to the servlet/controller, do your processing and then pass this value to the jsp page by putting it into some object's as your requirement. Then you can use this value as you want.

to find elements from last, use

<style>
ul li:nth-last-of-type(3n){ color:#a94442}  /**/
</style>

Use GETDATE()

Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running.

UPDATE table SET date = GETDATE()

You can hide a JPanel by calling setVisible(false). For example:

public static void main(String args[]){
    JFrame f = new JFrame();
    f.setLayout(new BorderLayout());
    final JPanel p = new JPanel();
    p.add(new JLabel("A Panel"));
    f.add(p, BorderLayout.CENTER);

    //create a button which will hide the panel when clicked.
    JButton b = new JButton("HIDE");
    b.addActionListener(new ActionListener(){
        public void actionPerformed(ActionEvent e){
                p.setVisible(false);
        }
    });

    f.add(b,BorderLayout.SOUTH);
    f.pack();
    f.setVisible(true);
}

Stored procedures:

(+)

• Great flexibility
• Full control over SQL
• The highest performance available

(-)

• Requires knowledge of SQL
• Stored procedures are out of source control
• Substantial amount of "repeating yourself" while specifying the same table and field names. The high chance of breaking the application after renaming a DB entity and missing some references to it somewhere.
• Slow development

ORM:

(+)

• Rapid development
• Data access code now under source control
• You're isolated from changes in DB. If that happens you only need to update your model/mappings in one place.

(-)

• Performance may be worse
• No or little control over SQL the ORM produces (could be inefficient or worse buggy). Might need to intervene and replace it with custom stored procedures. That will render your code messy (some LINQ in code, some SQL in code and/or in the DB out of source control).
• As any abstraction can produce "high-level" developers having no idea how it works under the hood

The general tradeoff is between having a great flexibility and losing lots of time vs. being restricted in what you can do but having it done very quickly.

There is no general answer to this question. It's a matter of holy wars. Also depends on a project at hand and your needs. Pick up what works best for you.

Probably the only choice is to read it on the client side and transfer it manually to the server (GET/POST/AJAX). Regards Artur

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

You'll probably want to try textContent instead of innerHTML.

Given innerHTML will return DOM content as a String and not exclusively the "text" in the div. It's fine if you know that your div contains only text but not suitable if every use case. For those cases, you'll probably have to use textContent instead of innerHTML

For example, considering the following markup:

<div id="test">
  Some <span class="foo">sample</span> text.
</div>

You'll get the following result:

var node = document.getElementById('test'),

htmlContent = node.innerHTML,
// htmlContent = "Some <span class="foo">sample</span> text."

textContent = node.textContent;
// textContent = "Some sample text."

See MDN for more details:

• textContent
• innerHTML

I find answer. Thanks all but right answer next:

$("#myModal").on("hidden", function () {
  $('#result').html('yes,result');
});

Events here http://bootstrap-ru.com/javascript.php#modals

UPD

For Bootstrap 3.x need use hidden.bs.modal:

$("#myModal").on("hidden.bs.modal", function () {
  $('#result').html('yes,result');
});

Have a look at Cassini. This is basically what Visual Studio uses for its built-in debug web server. I've used it with Umbraco and it seems quite good.

$.ajax({
        url: 'http://url.of.my.server/submit',
        dataType: "jsonp",
        jsonp: 'callback',
        jsonpCallback: 'jsonp_callback'
    });

jsonp is the querystring parameter name that is defined to be acceptable by the server while the jsonpCallback is the javascript function name to be executed at the client.
When you use such url:

url: 'http://url.of.my.server/submit?callback=?'

the question mark ? at the end instructs jQuery to generate a random function while the predfined behavior of the autogenerated function will just invoke the callback -the sucess function in this case- passing the json data as a parameter.

$.ajax({
        url: 'http://url.of.my.server/submit?callback=?',
        success: function (data, status) {
            mySurvey.closePopup();
        },
        error: function (xOptions, textStatus) {
            mySurvey.closePopup();
        }
    });

The same goes here if you are using $.getJSON with ? placeholder it will generate a random function while the predfined behavior of the autogenerated function will just invoke the callback:

$.getJSON('http://url.of.my.server/submit?callback=?',function(data){
//process data here
});

This is very helpful since that API's will change for sure and you can refactor once and very fast!

Don't get confused with the concepts of Angular and RxJS

We have pipes concept in Angular and pipe() function in RxJS.

1) Pipes in Angular: A pipe takes in data as input and transforms it to the desired output
https://angular.io/guide/pipes

2) pipe() function in RxJS: You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.
https://angular.io/guide/rx-library (search for pipes in this URL, you can find the same)

So according to your question, you are referring pipe() function in RxJS

@Nishit, JSONObject does not natively understand how to parse through a StringBuilder; instead you appear to be using the JSONObject(java.lang.Object bean) constructor to create the JSONObject, however passing it a StringBuilder.

See this link for more information on that particular constructor.

http://www.json.org/javadoc/org/json/JSONObject.html#JSONObject%28java.lang.Object%29

When a constructor calls for a java.lang.Object class, more than likely it's really telling you that you're expected to create your own class (since all Classes ultimately extend java.lang.Object) and that it will interface with that class in a specific way, albeit normally it will call for an interface instead (hence the name) OR it can accept any class and interface with it "abstractly" such as calling .toString() on it. Bottom line, you typically can't just pass it any class and expect it to work.

At any rate, this particular constructor is explained as such:

Construct a JSONObject from an Object using bean getters. It reflects on all of the public methods of the object. For each of the methods with no parameters and a name starting with "get" or "is" followed by an uppercase letter, the method is invoked, and a key and the value returned from the getter method are put into the new JSONObject. The key is formed by removing the "get" or "is" prefix. If the second remaining character is not upper case, then the first character is converted to lower case. For example, if an object has a method named "getName", and if the result of calling object.getName() is "Larry Fine", then the JSONObject will contain "name": "Larry Fine".

So, what this means is that it's expecting you to create your own class that implements get or is methods (i.e.

public String getName() {...}

or

public boolean isValid() {...}

So, to solve your problem, if you really want that higher level of control and want to do some manipulation (e.g. modify some values, etc.) but still use StringBuilder to dynamically generate the code, you can create a class that extends the StringBuilder class so that you can use the append feature, but implement get/is methods to allow JSONObject to pull the data out of it, however this is likely not what you want/need and depending on the JSON, you might spend a lot of time and energy creating the private fields and get/is methods (or use an IDE to do it for you) or it might be all for naught if you don't necessarily know the breakdown of the JSON string.

So, you can very simply call toString() on the StringBuilder which will provide a String representation of the StringBuilder instance and passing that to the JSONObject constructor, such as below:

...
StringBuilder jsonString = new StringBuilder();
while((readAPIResponse = br.readLine()) != null){
    jsonString.append(readAPIResponse);
}
JSONObject jsonObj = new JSONObject(jsonString.toString());
...

This error comes when using the following command in Windows. You can simply run the following command by removing the dot '.' and the slash '/'.

Instead of writing:

D:\Gesture Recognition\Gesture Recognition\Debug>./"Gesture Recognition.exe"

Write:

D:\Gesture Recognition\Gesture Recognition\Debug>"Gesture Recognition.exe"

var x = '<p>blah</p><div><a href="http://bs.serving-sys.com/BurstingPipe/adServer.bs?cn=brd&FlightID=2997227&Page=&PluID=0&Pos=9088" target="_blank"><img src="http://bs.serving-sys.com/BurstingPipe/adServer.bs?cn=bsr&FlightID=2997227&Page=&PluID=0&Pos=9088" border=0 width=300 height=250></a></div>';

Here is a non-numpy solution:

>>> a = [[40, 10], [50, 11]]
>>> [float(sum(l))/len(l) for l in zip(*a)]
[45.0, 10.5]

Note that callback syntax is deprecated:

Deprecation Notice

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

Here a modernized solution using the promise interface

$.ajax({url: "...", cache: false}).done(function( data ) {
    // data contains result
}).fail(function(err){
    // error
});

If you want to use asyncio, then requests-async provides async/await functionality for requests - https://github.com/encode/requests-async

As mentioned by @Brent in the comment of @maxymoo's answer, you can try

df.limit(10).toPandas()

to get a prettier table in Jupyter. But this can take some time to run if you are not caching the spark dataframe. Also, .limit() will not keep the order of original spark dataframe.

I created this toy example in scala, my_file.scala:

object MyObject {

    def main(args: Array[String]) {
        var ab = ArrayBuffer.empty[Int]

        for (i <- 0 to 100 * 1000 * 1000) {
            ab += i
            if (i % 10000 == 0) {
                println("On : %s".format(i))
            }
        }
    }
}

I ran it with:

scala -J-Xms500m -J-Xmx7g my_file.scala

and

scala -J-Xms7g -J-Xmx7g my_file.scala

There are certainly noticeable pauses in -Xms500m version. I am positive that the short pauses are garbage collection runs, and the long ones are heap allocations.

ptomato's code can also be written in a cleaner manner like:

ifeq ($(TARGET_CPU),x86)
  TARGET_CPU_IS_X86 := 1
else ifeq ($(TARGET_CPU),x86_64)
  TARGET_CPU_IS_X86 := 1
else
  TARGET_CPU_IS_X86 := 0
endif

This doesn't answer OP's question but as it's the top result on google, I'm adding it here in case it's useful to anyone else.

You could use jQuery's grep method:

$.grep(carBrands, function(obj) { return obj.name == "ford"; });

But as you specify no jQuery, you could just make a derivative of the function. From the source code:

function grepArray( elems, callback, inv ) {  
    var ret = [];  

    // Go through the array, only saving the items  
    // that pass the validator function  
    for ( var i = 0, length = elems.length; i < length; i++ ) {  
        if ( !inv !== !callback( elems[ i ], i ) ) {  
            ret.push( elems[ i ] );  
        }  
    }  

    return ret;  
}  

grepArray(carBrands, function(obj) { return obj.name == "ford"; });

Extending on Tadeck's Django answer above, the use of 'class Meta:' in Django is just normal Python too.

The internal class is a convenient namespace for shared data among the class instances (hence the name Meta for 'metadata' but you can call it anything you like). While in Django it's generally read-only configuration stuff, there is nothing to stop you changing it:

In [1]: class Foo(object):
   ...:     class Meta:
   ...:         metaVal = 1
   ...:         
In [2]: f1 = Foo()
In [3]: f2 = Foo()
In [4]: f1.Meta.metaVal
Out[4]: 1
In [5]: f2.Meta.metaVal = 2
In [6]: f1.Meta.metaVal
Out[6]: 2
In [7]: Foo.Meta.metaVal
Out[7]: 2

You can explore it in Django directly too e.g:

In [1]: from django.contrib.auth.models import User
In [2]: User.Meta
Out[2]: django.contrib.auth.models.Meta
In [3]: User.Meta.__dict__
Out[3]: 
{'__doc__': None,
 '__module__': 'django.contrib.auth.models',
 'abstract': False,
 'verbose_name': <django.utils.functional.__proxy__ at 0x26a6610>,
 'verbose_name_plural': <django.utils.functional.__proxy__ at 0x26a6650>}

However, in Django you are more likely to want to explore the _meta attribute which is an Options object created by the model metaclass when a model is created. That is where you'll find all of the Django class 'meta' information. In Django, Meta is just used to pass information into the process of creating the _meta Options object.

The answer above didn't work for me, what did eventually was this syntax:

curl https://${URL} &> /dev/stdout | tee -a ${LOG}

tee puts the output on the screen, but also appends it to my log.

To avoid this - one can use the GUI for entering permissions. Eclipse take care of where to insert the permission tag and more often then not is correct

What I'm currently doing Dec 2012 (combines most of these answers):

oldPath="vendor/example"
git config -f .git/config --remove-section "submodule.${oldPath}"
git config -f .gitmodules --remove-section "submodule.${oldPath}"
git rm --cached "${oldPath}"
rm -rf "${oldPath}"              ## remove src (optional)
rm -rf ".git/modules/${oldPath}" ## cleanup gitdir (optional housekeeping)
git add .gitmodules
git commit -m "Removed ${oldPath}"

In PHP DateTime (PHP >= 5.3)

$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->getTimestamp();

.git/HEAD contains the path of the current ref, the working directory is using as HEAD.

This

url = new URL("http://10.0.2.2:8080/HelloServlet/PDRS?param1="+lat+"&param2="+lon);

must work. For whatever strange reason¹, you need ? before the first parameter and & before the following ones.

Using a compound parameter like

url = new URL("http://10.0.2.2:8080/HelloServlet/PDRS?param1="+lat+"_"+lon);

would work, too, but is surely not nice. You can't use a space there as it's prohibited in an URL, but you could encode it as %20 or + (but this is even worse style).

^{1 Stating that ? separates the path and the parameters and that & separates parameters from each other does not explain anything about the reason. Some RFC says "use ? there and & there", but I can't see why they didn't choose the same character.}

The :: is called scope resolution operator. Can be used like this:

:: identifier
class-name :: identifier
namespace :: identifier

You can read about it here
https://docs.microsoft.com/en-us/cpp/cpp/scope-resolution-operator?view=vs-2017

I think this need to be run from the Management Shell rather than the console, it sounds like the module isn't being imported into the Powershell console. You can add the module by running:

Add-PSSnapin Microsoft.Sharepoint.Powershell

in the Powershell console.

setRetaininstance is only useful when your activity is destroyed and recreated due to a configuration change because the instances are saved during a call to onRetainNonConfigurationInstance. That is, if you rotate the device, the retained fragments will remain there(they're not destroyed and recreated.) but when the runtime kills the activity to reclaim resources, nothing is left. When you press back button and exit the activity, everything is destroyed.

Usually I use this function to saved orientation changing Time.Say I have download a bunch of Bitmaps from server and each one is 1MB, when the user accidentally rotate his device, I certainly don't want to do all the download work again.So I create a Fragment holding my bitmaps and add it to the manager and call setRetainInstance,all the Bitmaps are still there even if the screen orientation changes.

On Mac you need cmd + / to comment and uncomment.

You declare the variable as extern in a common header:

//globals.h
extern int x;

And define it in an implementation file.

//globals.cpp
int x = 1337;

You can then include the header everywhere you need access to it.

I suggest you also wrap the variable inside a namespace.

All the other answers are pretty good. But there’s an important usability detail about how ghc treats $, that the ghc type checker allows for instatiarion with higher rank/ quantified types. If you look at the type of $ id for example you’ll find it’s gonna take a function whose argument is itself a polymorphic function. Little things like that aren’t given the same flexibility with an equivalent upset operator. (This actually makes me wonder if $! deserves the same treatment or not )

In Ubuntu it looks like this :

 $ sudo apt-get install python-dev libldap2-dev libsasl2-dev libssl-dev
 $ sudo pip install python-ldap

If your XML goes quite deep, you might want to consider using XPath, which comes with your JRE, so you can access the contents far more easily using:

String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()", 
    document.getDocumentElement());

Full example:

import static org.junit.Assert.assertEquals;
import java.io.StringReader;    
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;    
import org.junit.Before;
import org.junit.Test;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;

public class XPathTest {

    private Document document;

    @Before
    public void setup() throws Exception {
        String xml = "<add job=\"351\"><tag>foobar</tag><tag>foobar2</tag></add>";
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        document = db.parse(new InputSource(new StringReader(xml)));
    }

    @Test
    public void testXPath() throws Exception {
        XPathFactory xpf = XPathFactory.newInstance();
        XPath xp = xpf.newXPath();
        String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
                document.getDocumentElement());
        assertEquals("foobar", text);
    }
}

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

https://github.com/networknt/jsontoken

This is a fork of original google jsontoken

It has not been updated since Sep 11, 2012 and depends on some old packages.

What I have done:

Convert from Joda time to Java 8 time. So it requires Java 8.
Covert Json parser from Gson to Jackson as I don't want to include two Json parsers to my projects.
Remove google collections from dependency list as it is stopped long time ago.
Fix thread safe issue with Java Mac.doFinal call.

All existing unit tests passed along with some newly added test cases.

Here is a sample to generate token and verify the token. For more information, please check https://github.com/networknt/light source code for usage.

I am the author of both jsontoken and Omni-Channel Application Framework.

GROUP BY 1

I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).

There's no need to run GROUP BY on the contents when you're using UNION - UNION ensures that duplicates are removed; UNION ALL is faster because it doesn't - and in that case you would need the GROUP BY...

Your query only needs to be:

SELECT a.id,
       a.time
  FROM dbo.TABLE_A a
UNION
SELECT b.id,
       b.time
  FROM dbo.TABLE_B b

global $wpdb;
$insert = $wpdb->query("INSERT INTO `front-post`(`id`, `content`) VALUES ('$id', '$content')");

It is good programming practice to return an empty array [] if the expected return type is an array. This makes sure that the receiver of the json can treat the value as an array immediately without having to first check for null. It's the same way with empty objects using open-closed braces {}.

Strings, Booleans and integers do not have an 'empty' form, so there it is okay to use null values.

This is also addressed in Joshua Blochs excellent book "Effective Java". There he describes some very good generic programming practices (often applicable to other programming langages as well). Returning empty collections instead of nulls is one of them.

Here's a link to that part of his book:

http://jtechies.blogspot.nl/2012/07/item-43-return-empty-arrays-or.html

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

craz demo

in regard of answer from @Perception, its true to be very memory-consuming when working with byte arrays, but you could also simply write back into the outputstream

@Path("/picture")
public class ProfilePicture {
  @GET
  @Path("/thumbnail")
  @Produces("image/png")
  public StreamingOutput getThumbNail() {
    return new StreamingOutput() {
      @Override
      public void write(OutputStream os) throws IOException, WebApplicationException {
        //... read your stream and write into os
      }
    };
  }
}

Well, if you are writing to a CSV file, then why do you use space as a delimiter? CSV files use commas or semicolons (in Excel) as cell delimiters, so if you use delimiter=' ', you are not really producing a CSV file. You should simply construct csv.writer with the default delimiter and dialect. If you want to read the CSV file later into Excel, you could specify the Excel dialect explicitly just to make your intention clear (although this dialect is the default anyway):

example = csv.writer(open("test.csv", "wb"), dialect="excel")

It was removed on purpose and it won't be coming back.

Both chrome://cache and chrome://view-http-cache have been removed starting chrome 66. They work in version 65.

Workaround

You can check the chrome://chrome-urls/ for complete list of internal Chrome URLs.

The only workaround that comes into my mind is to use menu/more tools/developer tools and having a Network tab selected.

The reason why it was removed is this bug:

You can convert a number to a string with n decimal places using the SPRINTF command:

>> x = 1.23;
>> sprintf('%0.6f', x)

ans =

1.230000

>> x = 1.23456789;
>> sprintf('%0.6f', x)

ans =

1.234568

What about using Excel Data Reader (previously hosted here) an open source project on codeplex? Its works really well for me to export data from excel sheets.

The sample code given on the link specified:

FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);

//1. Reading from a binary Excel file ('97-2003 format; *.xls)
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
//...
//2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
//...
//3. DataSet - The result of each spreadsheet will be created in the result.Tables
DataSet result = excelReader.AsDataSet();
//...
//4. DataSet - Create column names from first row
excelReader.IsFirstRowAsColumnNames = true;
DataSet result = excelReader.AsDataSet();

//5. Data Reader methods
while (excelReader.Read())
{
//excelReader.GetInt32(0);
}

//6. Free resources (IExcelDataReader is IDisposable)
excelReader.Close();

UPDATE

After some search around, I came across this article: Faster MS Excel Reading using Office Interop Assemblies. The article only uses Office Interop Assemblies to read data from a given Excel Sheet. The source code is of the project is there too. I guess this article can be a starting point on what you trying to achieve. See if that helps

UPDATE 2

The code below takes an excel workbook and reads all values found, for each excel worksheet inside the excel workbook.

private static void TestExcel()
    {
        ApplicationClass app = new ApplicationClass();
        Workbook book = null;
        Range range = null;

        try
        {
            app.Visible = false;
            app.ScreenUpdating = false;
            app.DisplayAlerts = false;

            string execPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().CodeBase);

            book = app.Workbooks.Open(@"C:\data.xls", Missing.Value, Missing.Value, Missing.Value
                                              , Missing.Value, Missing.Value, Missing.Value, Missing.Value
                                             , Missing.Value, Missing.Value, Missing.Value, Missing.Value
                                            , Missing.Value, Missing.Value, Missing.Value);
            foreach (Worksheet sheet in book.Worksheets)
            {

                Console.WriteLine(@"Values for Sheet "+sheet.Index);

                // get a range to work with
                range = sheet.get_Range("A1", Missing.Value);
                // get the end of values to the right (will stop at the first empty cell)
                range = range.get_End(XlDirection.xlToRight);
                // get the end of values toward the bottom, looking in the last column (will stop at first empty cell)
                range = range.get_End(XlDirection.xlDown);

                // get the address of the bottom, right cell
                string downAddress = range.get_Address(
                    false, false, XlReferenceStyle.xlA1,
                    Type.Missing, Type.Missing);

                // Get the range, then values from a1
                range = sheet.get_Range("A1", downAddress);
                object[,] values = (object[,]) range.Value2;

                // View the values
                Console.Write("\t");
                Console.WriteLine();
                for (int i = 1; i <= values.GetLength(0); i++)
                {
                    for (int j = 1; j <= values.GetLength(1); j++)
                    {
                        Console.Write("{0}\t", values[i, j]);
                    }
                    Console.WriteLine();
                }
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e);
        }
        finally
        {
            range = null;
            if (book != null)
                book.Close(false, Missing.Value, Missing.Value);
            book = null;
            if (app != null)
                app.Quit();
            app = null;
        }
    }

In the above code, values[i, j] is the value that you need to be added to the dataset. i denotes the row, whereas, j denotes the column.

I use this this code and works fine for me:

-(void)zoomToFitMapAnnotations:(MKMapView*)aMapView
{
    if([aMapView.annotations count] == 0)
        return;

    CLLocationCoordinate2D topLeftCoord;
    topLeftCoord.latitude = -90;
    topLeftCoord.longitude = 180;

    CLLocationCoordinate2D bottomRightCoord;
    bottomRightCoord.latitude = 90;
    bottomRightCoord.longitude = -180;

    for(MapViewAnnotation *annotation in mapView.annotations)
    {
        topLeftCoord.longitude = fmin(topLeftCoord.longitude, annotation.coordinate.longitude);
        topLeftCoord.latitude = fmax(topLeftCoord.latitude, annotation.coordinate.latitude);

        bottomRightCoord.longitude = fmax(bottomRightCoord.longitude, annotation.coordinate.longitude);
        bottomRightCoord.latitude = fmin(bottomRightCoord.latitude, annotation.coordinate.latitude);
    }

    MKCoordinateRegion region;
    region.center.latitude = topLeftCoord.latitude - (topLeftCoord.latitude - bottomRightCoord.latitude) * 0.5;
    region.center.longitude = topLeftCoord.longitude + (bottomRightCoord.longitude - topLeftCoord.longitude) * 0.5;
    region.span.latitudeDelta = fabs(topLeftCoord.latitude - bottomRightCoord.latitude) * 1.1; // Add a little extra space on the sides
    region.span.longitudeDelta = fabs(bottomRightCoord.longitude - topLeftCoord.longitude) * 1.1; // Add a little extra space on the sides

    region = [aMapView regionThatFits:region];
    [mapView setRegion:region animated:YES];
}

This did it for me...

//trim message to 100 characters, regardless of where it cuts off
$msgTrimmed = mb_substr($var,0,100);

//find the index of the last space in the trimmed message
$lastSpace = strrpos($msgTrimmed, ' ', 0);

//now trim the message at the last space so we don't cut it off in the middle of a word
echo mb_substr($msgTrimmed,0,$lastSpace)

You can add hash info in next page url to move browser at specific position(any html element), after page is loaded.

This is can done in this way:

add hash in the url of next_page : example.com#hashkey

$( document ).ready(function() {

  ##get hash code at next page
  var hashcode = window.location.hash;

  ## move page to any specific position of next page(let that is div with id "hashcode")
  $('html,body').animate({scrollTop: $('div#'+hascode).offset().top},'slow');

});

With VS 2017, debugging ASP.NET project with Chrome doesn't sign you in with your Google account.

To fix that go to Tools -> Options -> Debugging -> General and turn off the setting Enable JavaScript Debugging for ASP.NET (Chrome and IE).

If you used any plugin for seo then Check 1st your seo plugin settings.Then find out Noindex setting if Enable Media for Noindex then disable it.

Alternatively, you can also delete a Foreign Key Constraint from the SQL Server Management Studio itself. You can try it if the commands do not work.

1. Expand your database view.
2. Right Click on Table which has foreign key constraint. Choose Design. A tab with the information about table columns will open.
3. Right click on the column which has the foreign key reference. Or you can right click on any column. Choose Relationships.
4. A list of relationships will appear (if you have one) in a pop up window.
5. From there you can delete the foreign key constraint.

I hope that helps

Ahh. Because I missed the point of you initial post, here is an example which also ITERATES. The first example did not. In this case, I retreive an ADODB recordset, then load the data into a collection, which is returned by the function to client code:

EDIT: Not sure what I screwed up in pasting the code, but the formatting is a little screwball. Sorry!

Public Function StatesCollection() As Collection
Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim rs As ADODB.Recordset
Dim colReturn As New Collection

Set colReturn = New Collection

Dim SQL As String
SQL = _
    "SELECT tblState.State, tblState.StateName " & _
    "FROM tblState"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

With cn
    .Provider = DataConnection.MyADOProvider
    .ConnectionString = DataConnection.MyADOConnectionString
    .Open
End With

With cmd
    .CommandText = SQL
    .ActiveConnection = cn
End With

Set rs = cmd.Execute

With rs
    If Not .EOF Then
    Do Until .EOF
        colReturn.Add Nz(!State, "")
        .MoveNext
    Loop
    End If
    .Close
End With
cn.Close

Set rs = Nothing
Set cn = Nothing

Set StatesCollection = colReturn

End Function

One more version... (I think this one is pretty good)

static float NextFloat(Random random)
{
    (float)(float.MaxValue * 2.0 * (rand.NextDouble()-0.5));
}

//inline version
float myVal = (float)(float.MaxValue * 2.0 * (rand.NextDouble()-0.5));

I think this...

• is the 2nd fastest (see benchmarks)
• is evenly distributed

And One more version...(not as good but posting anyway)

static float NextFloat(Random random)
{
    return float.MaxValue * ((rand.Next() / 1073741824.0f) - 1.0f);
}

//inline version
float myVal = (float.MaxValue * ((rand.Next() / 1073741824.0f) - 1.0f));

I think this...

• is the fastest (see benchmarks)
• is evenly distributed however because Next() is a 31 bit random value it will only return 2^31 values. (50% of the neighbor values will have the same value)

...and when I got one how to process it (do I need to use Fourier Transform like it was instructed in the above post)?

If you want a "tap" then I think you are interested in amplitude more than frequency. So Fourier transforms probably aren't useful for your particular goal. You probably want to make a running measurement of the short-term (say 10 ms) amplitude of the input, and detect when it suddenly increases by a certain delta. You would need to tune the parameters of:

• what is the "short-term" amplitude measurement
• what is the delta increase you look for
• how quickly the delta change must occur

Although I said you're not interested in frequency, you might want to do some filtering first, to filter out especially low and high frequency components. That might help you avoid some "false positives". You could do that with an FIR or IIR digital filter; Fourier isn't necessary.

You can use useImmer opposed to useState and access the state. Example: https://css-tricks.com/build-a-chat-app-using-react-hooks-in-100-lines-of-code/

Here is my way:

function xml2array($xml_data)
{
    $xml_to_array = [];

    if(isset($xml_data))
    {
        if(is_iterable($xml_data))
        {
            foreach($xml_data as $key => $value)
            {
                if(is_object($value))
                {
                    if(empty((array)$value))
                    {
                        $value = (string)$value;
                    }
                    else
                    {
                        $value = (array)$value;
                    }
                    $value = xml2array($value);
                }
                $xml_to_array[$key] = $value;
            }
        }
        else
        {
            $xml_to_array = $xml_data;
        }
    }

    return $xml_to_array;
}

Use onkeyup on the text box and check the keycode of the key pressed, if its between 65 and 90, allow else empty the text box.

We of course all understand that there's no perfect way to solve this problem, but some solutions can get you farther than others.

In particular, it's pretty easy to go beyond simple whitespace-splitters if you just have some lists of common prefixes (Mr, Dr, Mrs, etc.), infixes (von, de, del, etc.), suffixes (Jr, III, Sr, etc.) and so on. It's also helpful if you have some lists of common first names (in various languages/cultures, if your names are diverse) so that you can guess whether a word in the middle is likely to be part of the last name or not.

BibTeX also implements some heuristics that get you part of the way there; they're encapsulated in the Text::BibTeX::Name perl module. Here's a quick code sample that does a reasonable job.

use Text::BibTeX;
use Text::BibTeX::Name;
$name = "Dr. Mario Luis de Luigi Jr.";
$name =~ s/^\s*([dm]rs?.?|miss)\s+//i;
$dr=$1;
$n=Text::BibTeX::Name->new($name);
print join("\t", $dr, map "@{[ $n->part($_) ]}", qw(first von last jr)), "\n";

If you have already installed app on your device, try to change bundle identifer on the web .plist (not app plist) with something else like "com.vistair.docunet-test2", after that refresh webpage and try to reinstall... It works for me

This is really handy, but I wanted a way to show all user objects, not just tables, so I adapted it to use sys.objects instead of sys.tables

SET NOCOUNT ON
DECLARE @AllTables table (DbName sysname,SchemaName sysname, ObjectType char(2), ObjectName sysname)
DECLARE
     @SearchDb nvarchar(200)
    ,@SearchSchema nvarchar(200)
    ,@SearchObject nvarchar(200)
    ,@SQL nvarchar(4000)
SET @SearchDb='%'
SET @SearchSchema='%'
SET @SearchObject='%Something%'
SET @SQL='select ''?'' as DbName, s.name as SchemaName, t.type as ObjectType, t.name as ObjectName 
from [?].sys.objects t inner join sys.schemas s on t.schema_id=s.schema_id 
WHERE t.type in (''FN'',''IF'',''U'',''V'',''P'',''TF'') 
AND ''?'' LIKE '''+@SearchDb+''' 
AND s.name LIKE '''+@SearchSchema+''' 
AND t.name LIKE '''+@SearchObject+''''

INSERT INTO @AllTables (DbName, SchemaName, ObjectType, ObjectName)
    EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY DbName, SchemaName, ObjectType, ObjectName

I was getting this problem when using IBM RSA 9.6.1 when building a brand new development machine. The problem for me ended up being because of HTTPS on the Global Maven repository. My solution was to create a Maven settings.xml that forced it to use HTTP.

The key to me was that the central repository was empty when I exploded it under Maven Repositories -- > Global Repositories

Using the following settings file worked for me:

<settings>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>insecurecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>insecurecentral</id>
      <!--Override the repository (and pluginRepository) "central" from the Maven Super POM -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>

I got the idea from this stackoverflow question.

Works on Swift 5+

import Foundation

let myString:String = "50"
let temp = myString as NSString
let myFloat = temp.floatValue
print(myFloat)  //50.0
print(type(of: myFloat)) // Float

// Also you can guard your value in order to check what is happening whenever your app crashes.

guard let myFloat = temp.floatValue else {
fatalError(" fail to change string to float value.")
}

An example of adaptive mergesort (optimized).

Adds support code and modifications to accelerate the merge when an auxiliary buffer of any size is available (still works without additional memory). Uses forward and backward merging, ring rotation, small sequence merging and sorting, and iterative mergesort.

Looks like the inner JSON struct is passed along as a string. You'll have to JSON.parse() it once more to get that data as an object.

try {
  responseData = JSON.parse(responseData);
}
catch (e) {}

Edit: Try the following:

$.ajax({
    type: 'GET',
    dataType: "json",
    url: "http://someotherdomain.com/service.svc",
    success: function (responseData, textStatus, jqXHR) {
        console.log("in");
        var data = JSON.parse(responseData['AuthenticateUserResult']);
        console.log(data);
    },
    error: function (responseData, textStatus, errorThrown) {
        alert('POST failed.');
    }
});

I couldn't import a different file.json too. But I resolved it like this

const swaggerDoc = require('../swagger.json')

try this :

public class FileStore
 {
   [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
   public Guid Id { get; set; }
   public string Name { get; set; }
   public string Path { get; set; }
 }

You can check this SO post.

There's no way you can do that changing only that line. You can do:

a = [1]
b = a
a[0] = 2
b[0]

That creates a list, assigns the reference to a, then b also, uses the a reference to set the first element to 2, then accesses using the b reference variable.

TOP (100) PERCENT is completely meaningless in recent versions of SQL Server, and it (along with the corresponding ORDER BY, in the case of a view definition or derived table) is ignored by the query processor.

You're correct that once upon a time, it could be used as a trick, but even then it wasn't reliable. Sadly, some of Microsoft's graphical tools put this meaningless clause in.

As for why this might appear in dynamic SQL, I have no idea. You're correct that there's no reason for it, and the result is the same without it (and again, in the case of a view definition or derived table, without both the TOP and ORDER BY clauses).

The key elements include:

1. the class="nav nav-tabs" and data-tabs="tabs" of ul
2. the data-toggle="tab" and href="#orange" of the a
3. the class="tab-content" of the div of the content
4. the class="tab-pane" and id of the div of the items

The complete code is as below:

<ul class="nav nav-tabs" data-tabs="tabs">
    <li class="active"><a data-toggle="tab" href="#red">Red</a></li>
    <li><a data-toggle="tab" href="#orange">Orange</a></li>
    <li><a data-toggle="tab" href="#yellow">Yellow</a></li>
    <li><a data-toggle="tab" href="#green">Green</a></li>
    <li><a data-toggle="tab" href="#blue">Blue</a></li>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="red">
        <h1>Red</h1>
        <p>red red red red red red</p>
    </div>
    <div class="tab-pane" id="orange">
        <h1>Orange</h1>
        <p>orange orange orange orange orange</p>
    </div>
    <div class="tab-pane" id="yellow">
        <h1>Yellow</h1>
        <p>yellow yellow yellow yellow yellow</p>
    </div>
    <div class="tab-pane" id="green">
        <h1>Green</h1>
        <p>green green green green green</p>
    </div>
    <div class="tab-pane" id="blue">
        <h1>Blue</h1>
        <p>blue blue blue blue blue</p>
    </div>
</div>

It depends..

SELECT x.col
FROM big_table x
WHERE x.key IN( SELECT key FROM really_big_table );

would not be relatively slow the isn't much to limit size of what the query check to see if they key is in. EXISTS would be preferable in this case.

But, depending on the DBMS's optimizer, this could be no different.

As an example of when EXISTS is better

SELECT x.col
FROM big_table x
WHERE EXISTS( SELECT key FROM really_big_table WHERE key = x.key);
  AND id = very_limiting_criteria

select fields FROM table WHERE date_created LIKE concat(LEFT(DATE_SUB(NOW(), interval 1 month),7),'%');

this one will be able to take advantage of an index if your date_created is indexed, because it doesn't apply any transformation function to the field value.

For me, this issue occurred after updating Google Play Services. One of the libraries I was using incorporated this library using the "+" in its gradel reference, like

compile 'com.google.android.gms:play-services:+'

This created an issue because the min version targeted by that library was less than what was targeted by the current version of Google Play Services. I found this by simply looking in the logs.

You can do something like this:

HTML:

<div class='div'>
<label>Something</label>
<input type='text' class='input'/>
<div>

CSS:

.div{
      margin-bottom: 10px;
      display: grid;
      grid-template-columns: 1fr 4fr;
}

.input{
       width: 50%;
}

Hope this helps ! :)
