Searching and Sorting - CH Ting
"Genome files are getting more numerous and larger. As a consequence searching them for specific patterns takes more time. I tried to optimize string compare and string search, with the machine instruction cmpsb. There are other strategies to reduce searching time for specific tasks such as Data Mining."

Paper & Pencil Electronics - Andreas Wagner
"I will briefly demonstrate my experiments with paper dielectric and pencil graphite capacitor, antenna, geometric diode, etc on my oscilloscope, and show a transistor that someone else got working. I don't have much to say about optimizing the geometry yet, but it's a step towards a (possible) from-scratch Forth computer."
