http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-sience/index.htm#Undergraduate provides a lot of materials of undergraute courses taught in MIT.
Another place is http://webcast.berkeley.edu/, which contains some realtime videos of the lectures in UC Berkeley.
From today on I will start to utilize these resources to find the entrance to the Computer Science area. Although programming is a kind of technical work, it can be scientific if you delve into it.
Hopefully I will start a brand new future.
Besides, this is my first personal blog. It doesn't matter whether there's any surfer would like to read. The important thing is, I am glad to write my feelings and share them on the internet.
