How can we compute the -neighbourhood of a point ? Mathematically it’s no problem, we can just write The first idea would be to exploit Haskell’s math friendly syntactic feature calld list comprehension which would yield neigh :: Int -> Searchpoint -> [Searchpoint] neigh d x = [y | y Searchpoint -> [Searchpoint] neigh d [...]
This week, the discounter Lidl sold Bresser USB microscopes for only 29,99EUR, so i got myself one, knowing that the quality would be rather poor. Provided I’ll have 10h of fun with it, that makes 3EUR/h, which is a good deal. As expected, Linux supports the microscope via the UCV drivers, so it’s literally plug [...]
Actually I wanted to build a hydrophone, but making a stethophone is just too easy. Besides: I gave my niece a stethoscope for Christmas, because we happen to play doctor fairly often and she has two “fake” stehoscopes for children that actually serve no purpose but being an ugly dummy. I got myself one, too, [...]
I like tweaking my config files in a lot so keeping /etc under revision control makes sense. My weapon of choice is git without any special reason. I’m actually used to svn but I don’t see the point in a central repository which leaves git and mercurial and this site nails it. So what’s actually [...]
I’ve been running Debian/testing on my desktop PC since 2004 without reinstalling anything and it has served me very well. Besides some minor problems, mostly with frustrating software like wine and Exim4, I’ve never ran into any serious problems. Debian is just great, but there are some reasons why Archlinux is better for me: Arch [...]

In my last blog I mentioned how baffled I was about the effectiveness of a very basic strategy for the mentioned dice game. I admit I’m not a coding nerd, quite the contrary: I made a grave mistake in the implementation and the results presented in my test runs represent a slightly different strategy. The [...]
