“Die Erde ist ein Irrenhaus. Dabei könnte das bis heute erreichte Wissen der Menschheit aus ihr ein Paradies machen. Dafür müsste die weltweite Gesellschaft allerdings zur Vernunft kommen.”

processing applets on playstation 3

i finally got ubuntu gutsy 7.10 working on my playstation 3. the current firmware 2.10 made some problems with the wireless connection. but i found a fixed kernel on the only problem now is the poor performance because of the 256 mb ram of the ps3 and the software rendering.

processing itself does not work yet. but with ibm’s java i got my processing applets working by calling them via appletviewer in the shell.

appletviewer index.html (it works with urls, too)


instantplayer and opensg did not compile yet. i tried to build opensg via deb source packages. but johannes will set up a build system for me next week.

give one – get one

i just ordered my XO laptop and donated one to a student in the third world. unfortunately they do not deliver it to germany. a friend in the usa will send it to me after it arrives. let’s see when i will reveice it and what it will cost me in the end. the dollar is low but shipping and customs are expensive..



i stranded with a rental car in the center of germany in a small village near the A7. the next morning a powerline crashed, the whole village was without energy and i had only credit cards with me. it was unbelievable that you could not even buy a coffee and get money from the bank. future!

the ec cashpoint tried to boot over and over again. it revealed that it’s running windows xp. is there an operation system with more vulnerable points for this purpose? unbelievable.


never use windows for installations..

.. unless you want to be embarrassed from time to time. i fought hard for only using linux and macs for installations at igd. normally drivers or a claimed ease of use are the arguments for windows. but you are paying the price soon.

in this example the public screens at the adidas store are showing a windows logo for several hours. whatever happened – a restart or an update – nobody reconized it.


windows embarrassed me several times, too. at a talk in ascona i had to present under windows because the projector did not work with linux. the antivirus software started scanning during the presentation. it took about 20 seconds to switch between the slides. last week i showed an augmented reality demonstration to european reviewers at a cultural heritage site in italy on a sony ux micro pc with windows vista. it worked great but when i restarted the computer afterwards microsoft’s wga thought i do not have a license anymore and shut it down. that was close.


the coperion installation – a multitouch table and a 8 meter wide hd projection – ran on ubuntu linux. it worked like a charm for 10 days.

broken macbook (literally)

i really like my macbook. unfortunately it literally breaks apart. there are long cracks around the case and around the ports. after 8 month it holds together with scotch tape. and it suffers the bluetooth / sleep problem apple denies.
