list the type of files in a directory. Usually quite useful information:

 file * 

go to the previous working directory:

cd -

also, bash has built in a stack for directories:

popdir

pushdir

Search the bash command history:

ctrl-r

List the bash command history:

then type !512 for command number 512.

There will be two pieces playing in the STRP festival featuring my work. One solo piece, Subjective referral backwards in time, and a collaboration piece with Bjarni Gunnarsson, Fallacies. They are both pieces for the Wave Field Synthesis, 192 speaker system of the Game Of Life Foundation. The pieces will be played automated during the days of the festival.

The time schedules will be:

18 November

• 20:00 –  Subjective referral backwards in time

19 November

• 17:15 – Subjective referral backwards in time

20 November

• 14:15 – Fallacies
• 17:45 – Fallacies

21 November

• 16:20 –  Subjective referral backwards in time

22 November

• 13:15 – Subjective referral backwards in time

23 November

• 10:00 – Subjective referral backwards in time

24 November

• 10:15 – Fallacies

• Cluster – a library for addressing multiple supercollider servers at the same time.
• SC-Wonder classes for interfacing between supercollider and the WONDER WFS system in Berlin.

Playing next week in Berlin at the SuperCollider symposium !

After seeing some benefits of it and listening to a lecture by Linus Torvalds on Git I was persuaded to switch to Git, at least to try it out in one project. I’m using GitX as a GUI, and I’m quite liking the process. It’s very easy to create branches, and to save the current working condition and go back to the previous state (git stash).

After all the exams are finished I will be posting the thesis here, together with some SuperCollider code.

Everyday Life

Everyday Life was made during a field recording workshop led by Justin Bennett at the Institute for Sonology in Den Haag, December 2009. The assignment was for the participants to document the sounds from their personal environment during a period of 24 hours. A group of the participants “reconstructed” their day by playing back the recordings according to an accelerated clock that counted through the 24 hours in about 30 minutes.

The DVD in Geluidpost is a live recording of the performance.

Performed / Recorded by: Gerben Kokmeijer, Tania Sikelianou, Yiannis Tsirkoglou, Pablo Sanz, Lucas Sancho, Matteo Marangoni, Miguel Negrao, Juan Cantizanni, Belinda Li, Bjarni Gunnarson, Baldur Bjornsson, Jakob Leben, Jasper Braet, Jasper Vanpaemel, Anna Mikhaylova, Jan Nieuwenhuis

IPv6 would solve all this, because there are almost an unlimited number of IPv6 adresses and each computer could have it’s own, becoming a first class citizen in the internet.

Now let’s think for a moment, who wouldn’t want what ? But off course, all the business operating on the internet that are based on the centralized model (such as the media industry, etc.). It’s not in their interest to adopt IPv6, because it’s not in their interest to have end users be in parity with the big business. And thus a whole bunch of excuses are being made to keep on using IPv4, and to cripple even more the capabilities of p2p traffic.
