Any article in *Ultrastudio.org* is partially a programming article, as the applet source code is available. This is especially true for bioinformatical or physical applets, as well as some mathematical applets like Matrix. However this additional category groups articles that have primary focus on the software developer, mainly describing some algorithms.
