Activities

Canvas 2D Web Apps

I've been thinking about how to teach programming web apps for some years. What is the best technology? What are the best tools? What is the best literature? I'm still not sure; thus, I'm writing a wikibook to try one approach. So far, I'm quite happy with the results: the book uses JavaScript and the HTML Canvas 2D Context and shows how to use this for a combination of automata-based programming and reactive programming. The resulting web apps can be used in desktop and mobile web browsers as well as in iBooks.

Cg Programming

After having spent quite a bit of time on the GLSL wikibook, I adapted it to Cg (and slightly extended it); mainly in order to provide students with more suitable learning material.

GLSL Programming

I've written a wikibook on GLSL (OpenGL Shading Language) programming to support a course that I've been teaching in October 2011. One of the basic ideas is to introduce learners to the way GLSL is used in context, in particular in Unity, Blender, and OpenGL+GLUT. This could be extended to WebGL, Android, and iOS. Notable feature: section numbers in the PDF version.

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've also been trying to better understand the possibilities of wikibooks in general.
