The [fantastic microbenchmark tool][1] created by MarkdownPapers&#39; author compares the performance for the following implementations:

  - MarkdownPapers
  - PegDown
  - Knockoff
  - MarkdownJ
  - TxtMark

TxtMark far exceeds the performance of the other tools, as shown in the following graph:

![Performance comparisons of markdown implementations][3]

PegDown, which supports many GitHub extensions and others, is far more fully featured. Custom plugins or extensions are also possible.

My use case involved processing markdown from an administrative screen where performance was less impactful than a rich feature set, which meant PegDown won over TxtMark.

I am using the select2 control, [loading data][1] via ajax. This requires the use of the `&lt;input type=hidden..&gt;` tag.

Now, I want to retrieve the selected text. (The `value` property in the `data-bind` expression sotres the `id` only)

I have tried `$(&quot;.select2-chosen&quot;).text()`, but this breaks when I have multiple select2 controls on the page.

I&#39;m trying to import a .sql file through PHP code. However, my code shows this error:


    There was an error during import. Please make sure the import file is saved in the same folder as this script and check your values:
    
    MySQL Database Name:	test
    MySQL User Name:	root
    MySQL Password:	NOTSHOWN
    MySQL Host Name:	localhost
    MySQL Import Filename:	dbbackupmember.sql

And this is my code:

    &lt;?php
    //ENTER THE RELEVANT INFO BELOW
    $mysqlDatabaseName =&#39;test&#39;;
    $mysqlUserName =&#39;root&#39;;
    $mysqlPassword =&#39;&#39;;
    $mysqlHostName =&#39;localhost&#39;;
    $mysqlImportFilename =&#39;dbbackupmember.sql&#39;;
    //DONT EDIT BELOW THIS LINE
    //Export the database and output the status to the page
    $command=&#39;mysql -h&#39; .$mysqlHostName .&#39; -u&#39; .$mysqlUserName .&#39; -p&#39; .$mysqlPassword .&#39; &#39; .$mysqlDatabaseName .&#39; &lt; &#39; .$mysqlImportFilename;

            break;
        case 1:

I&#39;m working on a Java EE web application with the following source code directory structure:

&lt;!-- language: lang-none --&gt;

    src/main/java                 &lt;-- multiple packages containing Java classes
    src/test/java                 &lt;-- multiple packages containing JUnit tests
    src/main/resources            &lt;-- includes properties files for textual messages
    src/main/webapp/resources     &lt;-- includes CSS, images and all Javascript files
    src/main/webapp/WEB-INF
    src/main/webapp/WEB-INF/tags
    src/main/webapp/WEB-INF/views

The folder I&#39;m interested in is `WEB-INF`: It contains `web.xml`, XML files for setting up servlets, Spring bean wiring contexts and JSP tags and views. I&#39;m trying to understand what constrains/defines this structure. E.g. do JSP files always have to be within `WEB-INF` or could they be somewhere else? And is there anything else that might go in `WEB-INF`? Wikipedia&#39;s [WAR files](http://en.wikipedia.org/wiki/WAR_file_format_%28Sun%29) entry mentions `classes` for Java classes and `lib` for JAR files - not sure I&#39;ve fully grasped when these would be needed in addition to the other source file locations.

What is WEB-INF used for in a Java EE web application?

Am I correct in thinking that the goodness of Cloud Endpoints comes with the following limitations:

 1. The REST Api cannot be deployed to a custom domain (it&#39;ll remain on appspot.com).
 2. The only authentication supported is OAuth against Google accounts.
  1. Corollary: it isn&#39;t currently possible to create a user login/session-tracking mechanism that is Google-accounts-agnostic (e.g., with email as username and a password).

Is there any plan to do away with these limitations and if so, what is the ETA?

For what function I can use in android to display the number into different formats.

For eg: 
If I enter 1000 then it should display like this 1,000.
If I enter 10000 then it should display like this 10,000.
If I enter 1000000 then it should display like this 1,000,000.

Please guide me.

I try files writer as follows: 

    String content = &quot;Test File Content&quot;;

* I used as like : `Files.write(path, content.getBytes(), StandardOpenOption.CREATE);`

If file is not create, file is created and content is written. But If file available , the file content is `Test File ContentTest File Content` and if the code is run repeat, the file content is `Test File ContentTest File ContentTest File Content` ...


* I used as like : `Files.write(path, content.getBytes(), StandardOpenOption.CREATE_NEW);` , 

If file is not create, file is created and than thow an exception as follow:

Can somebody please explain to me why this feature was added in JDK 7 and how it works?

While going through the new features of JDK 7, I found following code.

    int i;
    //Java 7 allows underscore in integer
    i=3455_11_11;

I know that `Monad` can be expressed in Scala as follows:

    trait Monad[F[_]] {
      def flatMap[A, B](f: A =&gt; F[B]): F[A] =&gt; F[B]
    }

I see why it is useful. For example, given two functions:

    getUserById(userId: Int): Option[User] = ...
    getPhone(user: User): Option[Phone] = ...

I can easily write function `getPhoneByUserId(userId: Int)` since `Option` is a monad:

    def getPhoneByUserId(userId: Int): Option[Phone] = 
      getUserById(userId).flatMap(user =&gt; getPhone(user))

...

Now I see `Applicative Functor` in Scala:

    trait Applicative[F[_]] {
      def apply[A, B](f: F[A =&gt; B]): F[A] =&gt; F[B]
    }

I wonder when I should use it _instead of_ monad . I guess both Option and List are `Applicatives`. Could you give simple examples of using `apply` with Option and List and explain _why_ I should use it _instead of_ `flatMap` ?

When and why should one use Applicative Functors in Scala

So, if I have an actor, I can give it a name. But, can I access that name internally? Example:

    class Actorz extends Actor with ActorLogging {
       val actorName = //??What function

       def receive = {
         case x =&gt; log.debug(actorName+&quot;: Received Message: &quot;+x)
       }
    }

    val actor = system.actorOf(Props[Actorz], &quot;named&quot;)
    actor ! &quot;dogs&quot;

Now, I can pass its name as a constructor parameter. But, that seems like unnecessary duplication if there is a way to get the name internally... as it was set when I instantiated the actor using `system.actorOf`. API docs didn&#39;t seem to have anything.

How can I get the name of an Akka actor from within the actor itself?

How can I merge maps like below:

    Map1 = Map(1 -&gt; Class1(1), 2 -&gt; Class1(2))
    Map2 = Map(2 -&gt; Class2(1), 3 -&gt; Class2(2))
    
After merged.
    
    Merged = Map( 1 -&gt; List(Class1(1)), 2 -&gt; List(Class1(2), Class2(1)), 3 -&gt; Class2(2))

Can be List, Set or any other collection who has size attribute.

I&#39;m using IntelliJ IDEA 13 (Community Edition) with the Scala plugin.

My initial import of an existing Scala project with a `build.sbt` worked fine.  The library dependencies were picked up by IDEA. Additional dependencies added after the initial import were not picked up, although I had checked the `auto-import` option.

Can one create a list (bullets, numbered or not) inside a markdown table.

A table looks like this:

    | Tables        | Are           | Cool  |
    | ------------- |:-------------:| -----:|
    | col 3 is      | right-aligned | $1600 |
    | col 2 is      | centered      |   $12 |
    | zebra stripes | are neat      |    $1 |

A list looks like this:

    * one
    * two
    * three

Can I merge them somehow?
