22C3: #1 day
December 28th, 2005 by teemowA short summary of my first day at 22c3:
libavg is a python library for easy media system development. Nice alternative not to use flash or director. It’’s already capable of video and 3d sound. Image editing will come soon…
I also watched three interesting talks about p2p algorithms, intelligent search engines and applied machine learning.
At first David Göthberg from randpeer described algorithms for node discovery and distributed hash tables to make an index available in serverless networks.
Isabel Drost (Humboldt Universität Berlin) first talked about search engine basics like in-/outlinks, pagerank and idf/tf. But she got a bit more into details when she explained how to remove spam from your search results (Support Vectors). It’’s a neverending game between spammer and spam filter so the best way to fight spam is to use machine learning. She also talked about search clustering (vivissimo), YaCy (p2p search engine) and Nutch (Java search engine based and written by the author of the already famous indexer lucene).
So it was perfect to stay in the same room and wait for the next talk about machine learning. The guys from the ”Intelligent Data Analysis Group” of Fraunhofer showed us some of their projects. Separating source code files from different authors in a project is not that complicated 
Afterwards I talked a little with Timon Schroeter from IDAG and Heiko Haller from AIFB Karlsruhe about machine learning and the categorization of texts with topic maps. Also someone (sorry I lost the name) from Leipzig University told me something about LSAwhich seems interesting.
Michael (the gentoo developer with an ubuntu notebook, ups didn”t want to make this public 
) also told me about SemperWiki, a Gnome desktop semantic wiki, which I am currently installing
