Felix has now a working progotype of a program that makes xturtle patterns and improve those patterns based on hte patterns that get most votes from the user.

By using (simple) Genetic_algorithm code, each pattern can pass sequences of "DNA" (tuples with xturtle-commands) to the "Child" pattern of the next generation. If the population maximum is reached, old (and ugly) patterns "die" to make room for younger -hopefully more pretty- "child" patterns.

While the program runs, the user(s) should express their opinion about the pattern by pressing the function keys several times. (F1 for ugly pattern, F8 for fantastic pretty pattern, F2 until F7 for in-between).

The program is best suited for run in a public spot with lots of users.

The program will run until the key "q" is pressed.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.
