Here you'll find some development projects mostly done by me to learn a specific subject. You can freely use, modify, rewrite, redistribute all the material. The only thing you can't do is to claim that you are the creator of them. All this is covered in GPL license which is applied to almost all material in this site.
I hope you find this site useful and feel free to send any suggestions and comments.
