Using a Function to create an Object in actionscript 3.0 <p>Since actionscript 3.0 is based on ECMAscript it shares some similarities with javascript. One such similarity that I have been playing around with is creating Objects from functions. </p>

<p>And can it be triggered via web requests as opposed to the command line? Or do I need to fake whatever $ENV variables and query strings and cookies that my script ... | <p>Assuming you want to profile your perl code, and not the server itself, the profilers generally do not care if it's mod_perl or mod_perl2, the major difference is in the apache API modules and what you can get apache to do for you using perl.</p>

java.util.logging.Logger doesn't respect java.util.logging.Level? <p>In plain Java SE 6 environment:</p>
<pre><code>Logger l = Logger.getLogger("nameless");
l.setLevel(Level.ALL);
l.fine("somemessage");
