The Abs Diet
Yeah! I did the abs diet and I can tell that was an enjoyable process. It isn’t a radical program to cut everything you eat. No, it is not. It is a program to help you learn how to eat properly.

Software

Fixed income and interest rate calculations made easy. It also comes in 2 flavours: R-fixedincome and python-fixedincome.
Sequela
Sequela is a web frontend for SQLite. It started as a Python project but at some point it turned into a JavaScript project. That was a great opportunity to learn JavaScript, Bootstrap and Jasmine (for unit testing).
csvgrep
A small Perl script that has been growing since its inception. The original purpouse was to help me handling csv files in command line. Surprisingly it has evolved to a tiny DSL. I have a lot of plans to improve it, but I can’t do in Perl, I can’t go that far. So, I’m always trying to write the Python version. Maybe someday.
easycsv
One more point in my track to make csv a useful format. Easycsv is a Python module that wraps the NoSQL library Storm. It processes the csv file and manage to execute some actions into a database table.
pyga
That is my first implementation of a Genetic Algorithm and it is in Python. This code has many flaws and I am trying to find some time to make it useful. Now the code is totally experimental so that it can only help others to implement a Genetic Algorithm from scratch.
