Felix moves the xturtle program now in the direction of genetic programming to make even more randomized patterns.

Thanks to the help of the xturtle author Gregor Lingl, the program runs now in an infinite loop until the mouse is clicked.

Also thanks to Gregor, if the xturtle leaves the screen she is re-teleported into the middle of the screen.

this is a terrible tutorial ! it's not a tutorial at all , it's a boy showing something that he made ! where is an explanation of what is going on ? where is an explanation of genetic programming ? this is supposed to be a python beginners tutorial so the expectation is that new concepts will be explained and their workings shown in some detail , not just a bunch of pretty colors on the screen and unknown code doing unknown things with no explanation of how it's done

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.



Showmedo's development is fairly rapid and bugs will inevitably creep in. If you have any problems please drop us a line using the contact address below. Likewise, any suggestions for improvements to the site are gratefully received.
