Note Taker

Seemingly pointless note taking day after day prompted me to write this program:

There's nothing magical about it - it simply ranks all the sentences in the input text and filters them accordingly. It's far from perfect, but its a useful little app anyway...

Sudoku I

Here is the first version of my Sudoku solver! It only solves very simple sudokus, otherwise it gives partial solutions.

It was originally supposed to be a program for my CASIO calculator, but BASIC tends to be a fickle language and it doesn't help that I get only 6 lines of code per screen.

So I ended up implementing it in C++ instead - click below for source and executable!

Naughts and Crosses

Tic-tac-toe games have been a common computer science exercise since the 50's, so I thought, why not?

This is an associative learning tic-tac-toe AI, based on positive feedback (check back later for a complete version with negative feedback as well). After a few thousand plays, the AI should be smart enough to beat you most of the time...

MD5 Rainbow Tables

A few assorted MD5 brute-forcing tools:
MD5 Hash: generates an md5 digest from ASCII string.
MD5 Rainbow: generates an md5 "rainbow table".
MD5 Lookup: uses an md5 "rainbow table" to reverse lookup a string from its hash.

MD5Rainbow asks for a string length and a character set, for example, to generate a rainbow table for 4-letter lowercase strings:

MD5 Rainbow Generator
Length of string: 4
Character set: abcdefghijklmnopqrstuvwxyz

FLV Audio Extractor

Many programs that download videos from, say, YouTube or Google Video to your computer, often download them in the form of a .FLV file. A lot of times, though, we want to rip the music from that video into MP3 form, etc... so the following program does just that - extracts audio from FLV's into separate files. This is far from a consumer version, first of all it is a command-line tool!

Usage is:
FLV_AudioExtract [input] [output].

For example:
FLV_AudioExtract sample_video.flv sample_video_music.mp3

The audio format may not always be MP3 - be sure to check the "Dominant format: ..." field, it will have something like mono 22 kHz mp3, which is the audio format.

Without further ado: http://www.box.net/public/dbzb0th7qt

Also included is a tag viewer for FLV files. I'm sure it will be self-explanatory. Big thanks to http://www.osflash.org for reverse engineering the FLV format!

Yahoo! Widgets Issue

I was logging into my Yahoo! Widgets(r) notepad one day when this happened... looks like someone forgot to fill in the default names!

Actually, this has never happened again, so I suppose it was due to my choppy internet connection... oh well.

Amino Acid Translation

While browsing NCBI's protein section of genome sequences, many of the protein amino acid sequences are in a cryptic one-letter code form, for example:

mapkksttkt

So, in order to make my reading experience a little more enjoyable, I've created a small program to translate that into a more readable sequence form, i.e.:

met- ala- pro- lys- lys-

Fruity Loops

I'm back again! A bit of fooling around with FL Studio 6 came up with the following clips:

Adelix's Nightmare
Sum Of Lore

I'll admit, they're both pretty mediocre, but...

Linear Regression

Another proof-of-concept application involving a form of statistical line-fitting. Once again, you'll need the .NET 2.0 Framework to run this.

Update 11/30: program now includes correlation calculations

Chaos Theory

Simple population growth isn't so simple if you extrapolate far enough! Chaos Theory is a small experiment to test out a common growth equation. Turn up the grwoth rate and be amazed (if you don't already know what Chaos Theory is!).

It may ask you for VB300.DLL (or something similar like that) to run depending on your system, a quick Google search will yield several downloads for that file.

Automated Spanish Homework

To save a bit of time looking up my Spanish homework, I wrote a program to do it automatically for the current day.

Not portable - if my Spanish teacher decides in any way to change the way she lists her homework, the program will be broken; requires Windows XP or 2000 with .NET Framework 2.0 to run.

Fourier Transform

Fourier Transform Experiment is a small program written a while back. It's never been finished (in the sense that some of the buttons/commands have not yet been implemented), but the basic bare-bones DFT works at least.

No manual, no instructions; proof-of-concept application only.

Source code is C# 1.1 using .NET 2.0; unchanged project directory can be downloaded here: http://www.box.net/public/lkphdpe918
