beyond expectation

waktu fall semester 2008 lalu saya habiskan di UCLA.
saya kira waktu ambil tutorial interdomain routing (BGP) bakal dapat hal hal-hal baru mengenai interdomain routing tapi harapan tinggal harapan ternyata hanya pertemuan pertama saja membahas interdomain routing (BGP) pertemuan-pertemuan selanjutnya malah berisi abstract algebra: ring theory, group theory, semi ring theory.
ini dia buku pegangannya:

Graphs, Dioids and Semirings

New Models and Algorithms
Series: Operations Research/Computer Science Interfaces Series , Vol. 41
Gondran, Michel, Minoux, Michel
2008, XX, 388 p. 26 illus., Hardcover
ISBN: 978-0-387-75449-9


Wolfram Research has worked with the CBS/Paramount show NUMB3RS since its first season. Now in the fifth season, it remains the most popular show of Friday nights. “The Math behind NUMB3RS” gives a more in-depth look at some of the mathematics in each episode. With season 5, we’ve added a math puzzle to go with each episode. Fifteen episodes into season 5, there are fifteen puzzles available.

arrgh!!! baru tau kalau Wolfram punya serial TV.
let's work on bittorrent
