Keep posting until habit becomes self-sustaining
I'm trying to turn this posting thing into a habit. A habit is something that you do naturally without having to set reminders. Basically, I want writing to become compulsive. For example, I love playing basketball, if I don't do it for too long, I start feeling weird and uncomfortable. Same with dancing, if I don't go out for too long, then I start feeling weird, stressed, overwhelmed. Same with reading, if I don't read, I start feeling like I'm getting dumber and losing touch with the world. I want writing to become just like that. I don't want to have to remind myself to post, I want to just post and feel weird when I don't. I'm doing it because I realize that information is best past down through writing and reading. I want writing to become second nature so that when I need to pass down information (some call it publishing research) that I don't have to deal with the sense of burden that comes with writing. That's it, just keeping it short.

Today I learned about TCP
I just read the TCP segment of my computer networks book and it's amazing how much more you can learn by re-reading something. I learned about TCP congestion control and TCP fairness. I think the most important thing that I learned is that TCP is not really fair after all. Since TCP fairness is based on TCP connections not hosts. What does that mean? It simply means that if my computer has 5 concurrent TCP connections and your computer has one and the bandwidth is evenly shared across the six connection, meaning I get 5 times more TCP bandwidth than your computer. This explain why torrent downloads slows down Web browsing traffic because these clients usually have 20 to 30 simultaneous TCP connections being shared by the bandwidth. The other thing is that UDP has no concept of fairness, so it can consume all of your bandwidth and not leave any space for TCP. I'm glad I read today, I hope I can read some more tomorrow.
