Inkscape SVG-File
Sometimes I'd like to accidentally leave my homework somewhere on the bus, just to scare people. What you see opposite is actually not a black hole bomb but, well... a deterministic finite state automaton, which accepts binary numbers, divisable by five. But of course you recognized that yourself ;-)

Simple, eh?

Addendum 2009-5-26
Because some people asked me for it, here's the task:
Construct a deterministic finite state automaton which accepts all binary numbers divisable by five. The low-order bit is read first.

I've done the task three hours before the deadline and I do not insist, that this is the best solution. If you send me your smaller automata (under GFDL or CC-by-sa or any license with even lesser restrictions) I will put them on this site too. I will even inkscape the first automata you send me.

PS: Yes, thats my actual e-mail-address, you got a problem with that?

Upgraded my homeserver today from an old Ubuntu LTS to Debian Lenny. Hack, the installer is beautyful!
I've been delaying the upgrade for a while now because I was really frightened to screw my software RAID- and LVM-setup. But that didn't happen. The installer perfectly detected the md-RAID as well as the LVM-Partitions and included everything in its nice partition setup tool. There were no problems booting the system with the whole setup. That was different from Ubuntu where I had to tinker around for a week to get the thing running.

Excelent work by The Debian pals.

Something funny happened to me today. I was sitting in a public train and beneath me sat a young man and a woman, they were talking about her computer. He mentioned that she would also need an operating system on her new machine, and asked what she's going to install and she answered that she doesn't care so much about that topic and will probably "just install an Ubuntu or something". He gave her a confused look and in an attempt to make her insecure about her excelent choice he began talking like: "but there is nothing you can run on it", "nobody uses it anyway", etc..., heard it a thousand times.
Before he could really get into it I raised up from my seat produced a flyer of LinuxWorks! and gave it to him wordlessly. Man, you should have seen his face.

Got another one! ;-)

Recently I had to listen, once more, to anxious and uninformed worries concerning the use of wireless network technology. I do not generally think that electromagnetic radiation is harmless in any case, and I believe that everyone should come to own conclusions about the pros and cons of radio technology. Therefore I want to support people in thinking about WIFI radiation for themselfes by giving a commonly understandable explanation of the technical part behind this ecological discussion...
