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 [...]
Everyone with a DVB-T receiver knows that the tuner signal can get corrupted by the weather or in my case the bus which stops in front of the house I live in. Some DVB-T receivers display the tuner signal in an OSD of your TV. Since I’m using a DVB-T card in my PC with [...]
I’ve gathered a lot of sci-fi books in 2010, mostly from flea markets for around about 50c each. The publisher Heyne has its own science fiction series and makes it easy for scifi-nerds to find by printing white “SF” letters onto the black back of the book. If you happen to pile up a certain [...]
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 finally added autocompletion for my TV channels for mplayer which is far superior to my previous method of looking up the exact channel’s name in my channels.conf and typing mplayer dvb://”channel’s name” in a terminal. I just added this very simple script to /etc/bash-completion.d/ _channel() { local cur COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}" local chans=$(cat .mplayer/channels.conf |sed [...]
Every time i listen to this it gets scarier… Mau!
Okay, this is pure nonsense, but anyway, I’d like to share some thoughts in order to quantify and in some way “locate” god. The whole idea is to work with distances, everyone can measure his or her felt distance to some objects, things or even thoughts. While it’s hard to actually give numbers to those [...]
I have an account at dimeadozen, a torrent tracker “for audio and video recordings of independent origin (ROIO) which have not been officially released“. If you know me you’re aware of my hobby of recording concerts. Dime is by far the best resource to share those recordings although I appreciate archive.org‘s approach, too. I don’t [...]
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 [...]
