### Activities

#### Cg Programming

After having spent quite a bit of time on the GLSL wikibook, I started a wikibook on Cg; mainly in order to provide students with appropriate learning material.

#### GLSL Programming

I've started a wikibook on GLSL (OpenGL Shading Language) programming to support a course that I'm teaching in October 2011. One of the basic ideas is to introduce learners to the way GLSL is used in context, e.g. in Unity, Blender, OpenGL+GLUT, HTML5, Android, PowerVR, iOS, instead of focussing on some standard that appears irrelevant to learners. If you want to learn Portuguese as it is spoken in Brazil, you shouldn't learn the Portuguese spoken in Portugal. It might help, but why waste your time?

#### German

I've been working a bit on reorganizing German, making the Level II levels accessible again and trying to integrate the exercises in the Level I lessons. There is still a lot of work to do on this book but I'm not really finding the time or motivation to do it.

#### Spanish by Choice

I'm the main author of Spanish by Choice, a collection of wikibooklets for everyone who wants to learn Spanish. With this wikibook I'm also trying to better understand the possibilities of wikibooks in general. There could be a lot of stuff done with the Novelas Cortas because there are excellent open-source audio recordings available but I'm not quite sure how to do it with reasonable effort.

 Here are some open Spanish by Choice tasks: SHORT TERM: currently none MIDDLE TERM: Edit: change copyright notice hyperlinks for notes in Spanish by Choice/Novelas Cortas add links to some dictionaries in the vocabulary list of Spanish by Choice/Novelas Cortas Add: PDF version of Spanish by Choice/Novelas Cortas LONG TERM: Add: translation of Spanish by Choice/Novelas Cortas Feel free to edit this list or discuss these tasks.
