I have been adding interesting articles to the reference list. I have not made copies of most of the articles, but at least there are some new references. There are some new articles on caching and I/O will be the next subject. Suggestions:

• Read something about Computer Architecture. The CACM or the SigArch (ACM special interest group on Architecture) or IEEE Micro are good places to look.
• Read something on I/O. There are a couple of historical articles on I/O performance in the reading list.
• I put a few Usenix conference proceedings in the cs terminal room - please return the proceedings.
• Also, on the Sun web pages are some whitepapers on semaphores, threads, etc.
