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

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

From time to time you may have reasons to override the default find method that ActiveRecord provides. In this example, we'll store a side-copy of the record attributes so that we have some basis for discovering changes to the data.

note: this will not override dynamic finders such as find_by_id

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

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.

A very simple script to generate random hexa colors.
