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.

Search file directory (recursive method) with java language

This is a Tiny PHP Uploading script. It SHOULD be safe from both really large files and non-image files.

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.

Use this utility to grab lines from a file. Arguments are the input file, starting ling number and ending line number.

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 function simply splits a file based on the splitter supplied and returns an array with the values. It's pretty much like the file() function. This script could be helpful in section editings.

This snippet illustrates using Genetic Algorithm for the hardware optimization.
