increasing java heap size in build file

I recently had to increase the java heap size for running my program. This did not seem obvious in the first few hits from google


<target name="run" depends="compile">
<java fork="true" classname="your.class.name">
<classpath>
<path refid="classpath" />
<path location="${dist}/parallelImpl.jar" />
</classpath>
<jvmarg line="-Xms256m -Xmx3000m" />
</java>
</target>

This specifies a minimum size of 256 MB and a maximum size of 3000MB.

A good article about java memory management

Using Zend Picasa API for getting details for last 10 public images

Here is some php code
This PHP code can be used to get

• The last 10 public pics for a user
• The URL's to the original images
• The URL's to the thumbnails
• The URL's to the original Picasa page where the images are hosted.

(please pardon the formatting)
<?php

/*
display the last 10 public picasa pics for the user

require_once 'Zend/Loader.php';
