CSE 80 -- Lecture 13 -- Feb 18

I gave out the take-home midterm. This is due in class Feb 20.

I finished going over the ra_no_ads script, especially the tricky I/O descriptor stuff on the xterm line.

I started to talk about TCP/IP networking and mentioned the HTTP protocol, and the reason why RealAudio uses UDP datagrams (a simple interface to IP, but with some restrictions so normal users can't spoof packets etc.)
