This was intended to be a page holding tutorials that were different from most others. I meant to explain various topics which interested me and which I had previously had trouble finding good introductions to. The reality is that it takes a lot of time to actually explain things in detail, so this page is currently not all that I intended it to be. I will try to get around to writing some more in the, hopefully, near future.
There may be errors in my texts. Consider what I write just another source of potential usefull information. Maybe a slightly different view on things than what most other, more detailed texts, provide. If you find actual errors, please let me know.
