Just a quick note on audio editing under Ubuntu. I just wanted to cut and reassemble different songs. At first I tried Audiacity. Maybe I did not give it enough process priority or I missed some settings, but it kind of lagged and the playback was somewhat indeterministic. A very well working alternative is Ardour.

This is how to input ASCII codes in Ubuntu: http://wiki.ubuntuusers.de/Sonderzeichen. Basically use the Alt Gr and Alt Gr + Shift with some keys
I am probably just stupid, but I could not for the live of me find well-known text representations of the world's continents. I finally did it myself. Very, VERY coarse, mind you using the OpenLayers WKT Example and Wikipedia as a reference. This works for my purposes. Feel free to tell me were I can Continue reading →
I tried to put float environments into framed box environments. All my attempts failed though. In the end I had to do it the other way around and put the boxes into the float.

I have a friend who wanted to get to work the program "Orbital" (http://www.itp.tu-berlin.de/menue/lehre/owl/quantenmechanik/wasserstoff-orbitale/parameter/maxhilfe/). The problem was that Orbital uses JOGL 1.1.1 (http://en.wikipedia.org/wiki/Java_OpenGL) in order to run the Webstart application. Webstart requires signed dependencies (JAR files) to be signed. Yet JOGL 1.1.1 is old and is not signed anymore by Oracle (http://www.java-gaming.org/index.php?topic=24806.0). There are two Continue reading →
