superplonk

Sunday, January 27th, 2008

in accelerando charles stross’ writes about alot of interesting concepts we are just starting to work on and i am covering in my dissertation. it was one of the most important books for me in 2007. it shows how close science fiction and science get in these days.

my favorite feature is superplonk. it remixes the environment and filters annoying persons, objects and sounds. that’s an augmented reality version of what i practice today with special earplugs. but soon that should be possible with modified hearing devices and slim head mounted displays.

one experiment in my ongoing surveillance series simulates superplonk with images of network cameras. via motion detection i am reconstructing a place’s image without people and cars. all moving objects are becoming ghosts. only people and cars who are standing still are becoming visible. movement makes you invisible. jan covers this topic in his master thesis, too.

surveillance update

Sunday, January 27th, 2008

SurveillanceSaver:
dan joined the development and started the windows version of the screen saver. it is quite finished yet. unfortunately he is offline during the week due to his job. but it should be released soon.

i added a lot of new cameras. not only axis but mobotix, panasonic, etc are in the list right now. it was not easy to get the urls of the cameras because google kicked my bot after some requests. inurl requests are blocked by google after the 12th page and limited to 1000 results. i found a nice workaround that gave me some more results but not all of them.

the new version of the mac version will be delayed thanks to apple and gravis. my macbook is broke since more than one month. they sent it back twice with defect logic boards. now they are trying again to repair it and refuse to give me a new one. that’s so annoying.

cameras in google earth
i processed a kml file of the geolocalized camera urls:

processing applets on playstation 3

Saturday, January 5th, 2008

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 psubuntu.com. 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.
