Big Numbers, Steep Slopes · Check out these numbers and graphs from Dave Sifry. Like I keep saying, I’ve seen this movie before, and it was ten years ago, and it was called The Web then.
Latency · [For Java/networking geeks only.] I have these two Java programs, talking through an ordinary TCP/IP socket. The client sends a (medium-sized) serialized object to the server, which does a little bit of computation and acknowledges by sending a (small) object back. Straight
writeObject()/readObject() calls with setTcpNoDelay(true) in effect. When both of them are running on my 1.25Ghz PowerBook here, the latency required for the whole transaction is like 190msec, which is horrible. So I moved the server code down to the mouldy old P300 Debian box in the basement, talking to it over two or three legs of WiFi and Ethernet switches, and the latency dropped to around 33msec; still not great, but the difference is instructive.California Wedding · Last weekend we went to a wedding in Santa Clara and had fun and took pictures. Best wishes to Rohit and Smruti! ...
