Another relatively quick option is 

    str = &#39;%0999999d&#39; % 0

Though benchmarking

    require &#39;benchmark&#39;
    Benchmark.bm(9)  do |x|
      x.report(&#39;format  :&#39;) { &#39;%099999999d&#39; % 0 }
      x.report(&#39;multiply:&#39;) { &#39;0&#39; * 99999999 }
    end

Shows that multiplication is still faster

                   user     system      total        real
    format  :  0.300000   0.080000   0.380000 (  0.405345)
    multiply:  0.080000   0.080000   0.160000 (  0.172504)


How can I get the domain name with jquery ?? 



jquery, domain, get URL

Our company is developing an API for our products and we are thinking about using ASP.NET MVC.  While designing our API, we decided to use calls like the one below for the user to request information from the API in XML format:

[http://ws.audioscrobbler.com/2.0/?method=artist.getimages&amp;artist=cher&amp;api_key=b25b959554ed76058ac220b7b2e0a026][1]

As you can see, multiple parameters are passed (i.e. `artist` and `api_key`).  In ASP.NET MVC, `artist` would be the `controller`, `getImages` the action, but how would I pass multiple parameters to the action?  

Is this even possible using the format above?

What is the best way to generate a long string quickly in ruby?  This works, but is very slow:

    str = &quot;&quot;
    length = 100000
    (1..length).each {|i| str += &quot;0&quot;}

I&#39;ve also noticed that creating a string of a decent length and then appending that to an existing string up to the desired length works much faster:

    str = &quot;&quot;
    incrementor = &quot;&quot;
    length = 100000
    (1..1000).each {|i| incrementor += &quot;0&quot;}
    (1..100).each {|i| str += incrementor}

Any other suggestions?

I have a rake task where I do some checks at the beginning, if one of the checks fails I would like to return early from the rake task, I don&#39;t want to execute any of the remaining code.

I thought the solution would be to place a return where I wanted to return from the code but I get the following error

    unexpected return

How do I return early from a rake task?

I&#39;m trying to use Ruby 1.9.1 for an embedded scripting language, so that &quot;end-user&quot; code gets written in a Ruby block.  One issue with this is that I&#39;d like the users to be able to use the &#39;return&#39; keyword in the blocks, so they don&#39;t need to worry about implicit return values.  With this in mind, this is the kind of thing I&#39;d like to be able to do:

    def thing(*args, &amp;block)
      value = block.call
      puts &quot;value=#{value}&quot;
    end

    thing {
      return 6 * 7
    }

If I use &#39;return&#39; in the above example, I get a LocalJumpError.  I&#39;m aware that this is because the block in question is a Proc and not a lambda.  The code works if I remove &#39;return&#39;, but I&#39;d really prefer to be able to use &#39;return&#39; in this scenario.  Is this possible?  I&#39;ve tried converting the block to a lambda, but the result is the same.

In JavaScript this is how we can split a string at every 3-rd character

    &quot;foobarspam&quot;.match(/.{1,3}/g)

I am trying to figure out how to do this in Java. Any pointers?

Splitting a string at every n-th character

I noticed in the Java 6 source code for String that hashCode only caches values other than 0. The difference in performance is exhibited by the following snippet:

    public class Main{
       static void test(String s) {
          long start = System.currentTimeMillis();
          for (int i = 0; i &lt; 10000000; i++) {
             s.hashCode();
          }
          System.out.format(&quot;Took %d ms.%n&quot;, System.currentTimeMillis() - start);
       }
       public static void main(String[] args) {
          String z = &quot;Allocator redistricts; strict allocator redistricts strictly.&quot;;
          test(z);
          test(z.toUpperCase());
       }
    }

&lt;a href=&quot;https://web.archive.org/web/20000000000000/http://www.ideone.com/Ho9lfOKy&quot;&gt;Running this in ideone.com&lt;/a&gt; gives the following output:

    Took 1470 ms.
    Took 58 ms.

So my questions are:

 * Why doesn&#39;t String&#39;s hashCode() cache 0?
 * What is the probability that a Java string hashes to 0?
 * What&#39;s the best way to avoid the performance penalty of recomputing the hash value every time for strings that hash to 0?
 * Is this the best-practice way of caching values? (i.e. cache all except one?)

I&#39;m getting `$row[&#39;message&#39;]` from a MySQL database and I need to remove all whitespace like `\n` `\t` and so on.

    $row[&#39;message&#39;] = &quot;This is   a Text \n and so on \t     Text text.&quot;;

should be formatted to:

    $row[&#39;message&#39;] = &#39;This is a Text and so on Text text.&#39;;


I tried:

     $ro = preg_replace(&#39;/\s\s+/&#39;, &#39; &#39;,$row[&#39;message&#39;]);
     echo $ro;

but it doesn&#39;t remove `\n` or `\t`, just single spaces. Can anyone tell me how to do that?
