Okay, the weather here is really terrible, it's switching between raining and very hot sun weather. So yesterday I wasn't motivated to watch many talks.
In the evening there was a very interesting talk
from John Gilmore about drugs and medical research. He is working on a project to find out if MDMA (Ecstasy) and other illegal drugs could be used as a legal medicament for certain issues. He's a very impressing person. At the end, the discussion turned from the medical view to drug politics in general.
This morning I was watching a talk about hashing functions, which again stated that it's no good idea to use SHA-1 and MD5 any more.
