A simple algorithm to convert decimal numbers to binary; pointless since most languages have an inbuilt function but was used for learning about algorithm design.

The decrypter for the simple encrypter I posted earlier - Takes the encrypted text from a text file - "encrypt.txt" which the encrypter automatically writes to.

A quick implementation of an encrypter which can't be cracked by frequency analysis.

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.

This module is a Python Library to support all IP2Location™ database products. It has been optimized for speed and memory utilization. Developers can use the API to qeury all IP2Location™ binary databases for applications written in Python.

This snippet illustrates using Genetic Algorithm for the hardware optimization.

Genetic Algorithm implementation.

Weighted random selection from the list.

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

This snippet illustrates following:

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

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