Informatics (mainly Computer Science) is currently one of my strongest interests, as it spans several interesting topics.  At the most theoretical, computer science topics can be incredibly tricky and abstract with, in some cases, extremely elegant solutions.  At the most practical, computer science is applied in the form of applications and programs that are useful for all sorts of purposes.  I find both extremes to be very interesting, and as such, will try to cover both sides.  The “theoretical topics” will mainly be a reference for all sorts of moderate and advanced topics, while “programs” will be for specific applications that I have written.
