Customizable recursive directory scanner.

This code illustrates using ruby REXML package. It converts J2EE web application deployment descriptor web.xml into Freemind mindmap document.

Genetic Algorithm implementation.

When doing a lot of testing in script/console, you often have to reload to pickup changes in DB schema, models and libs. The process of quitting the console and restarting it can become incredibly tedious amidst bugtracking.

note: I don't believe this reloads items in the libs dir

Weighted random selection from the list.

Don't forget to call itemsChanged after updating list content.

This snippet illustrates using Genetic Algorithm for the hardware optimization.

This class intended to collect TODO comments from java/c++/etc source files.

Example:

protected readFileData (String path) throws IOException {
// TODO: add try...catch block for IOException
InputStream is = new FileInputStream(path);
...
}

This class illustrates mixed GUI/command line parameters passing. Any parameter may be specified in the command line. All unspecified parameters will be read using GUI dialog box.

This snippet illustrates following:

1. Using http request to get the data
2. Parsing RSS feeds
3. Sending email

I'm in the process of writing test fixtures for our rails site. A lot of my tests require authentication, so I've had to port our permissions system into a fixture. Rather than type out all of the information for the fixture, I decided to create a nested loop that will take care of this for me.

There's probably a rake task for this, but I wasn't able to find it, so I came up with my own solution. You'll have to do a little cleanup when it's done, however some slight mods to this loop could even eliminate that.
