Back to work

I had a good lecture a while ago on Threads. It feels good because I feel like it's been a while that I really haven't been "teaching". Anyway, I'll try my best to do better. Research, research, research..

Zen asked me about hyperthreading. I don't know much about the subject but I found this nice article that explains the topic quite well.

I also found a good article about multithreading in Java, which would be very beneficial to you, dear student, if you only take time to read it. =)
