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.

IP2Location is a Ruby library that enables the user to find the country, region, city, coordinates, zip code, ISP and domain name that any IP address or hostname originates from. It has been optimized for speed and memory utilization. Developers can use the API to query all IP2Location™ binary databases for applications written in C or supporting static/dynamic library.

This snippet illustrates using Genetic Algorithm for the hardware optimization.

Genetic Algorithm implementation.

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.

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.
