who am i? a bit of a, a bit of b, or maybe c?

c# doesnt allow multiple inheritance because of all the mess which can be caused by it.. however i was really fascinated by an article on codeproject, describing some workarounds. i'm still not convinced that i ever will apply their solution, but i still enjoyed the read ;)

do your maths

you WILL need it in some unexpected moments... it just will creep around in the darkness and suddenly jump in your face! especially these matrix transformations, they seem to love playing these games...

my math teacher would feel touched by how much i now try to remember her explanations ;)

one night and one day of real holiday

today i had one of the most wonderful days in a long time at the former place of my grandparents. the setting was as follows:

no mobile phone





no internet or computer






thanks to these uncommon surroundings i've been experiencing a whole set of things which not usually come my way:


sleeping on a bag full of hay, which was quite strange at first, but had a really nice odour, which made me sleep soo well :)


with a very nice sight when waking up (and having breakfast outside ;)


i went strolling round the village,


playing with some calves


and then heated the oven - yes, with a proper fire!


on which we were baking our own bread, some even with fresh herbs.








apart from all these things, i've been re-exploring all the things which i knew as a kid - the whole place is so much smaller now! but it was perfect to be there, enjoy the beauty of it as well as a lot of nice memories of long gone times.

Airborne Ultrasound Tactile Display

Airborne Ultrasound Tactile Display is a display technology for creating holograms one can actually 'touch' and manipulate with hands.
i'm really impressed with what one can construct with some wii-motes and ultrasound.. but see for yourself!

everyday things

some news make the world seem like an economy strategic game, where after a bad strategy a message turns up telling: "your toilet paper supplies are running low"

friday, 2pm

i wonder if there is a worse time for working in an office. lunch is just over, the stomach is full, it is hot outside, i am feeling totally sleepy. then, it's not even enough time for seriously starting a new task, as till monday i will have forgotten what i could not finish.
apart from that, outside the lake is waiting for visitors..

munich

here's a short movie presenting the city. i'm not so happy about the music, but some of the places are well worth visiting and as nice as on the video ;)
