Linux at CS Department

one of our most "visible" graduates: Dr. Linus Torvalds, who graduated from our NODES group


concerning sport, I am a Point Guard (PG) since age 10, representing high school and faculty of science at college. After moving to Helsinki, I've also played with many Finnish and European players. My PG role model is John Stockton.

a quote from my coach about PG, "reading a game well is really hard, but extremely fun, especially for those who understand the beauty of teamwork and the opportunity behind every move."


Aaron is from city Changsha, the capital of Hunan province (of similar size and population to UK)
