The water is at least a foot lower than before and the small pool in the background is about the only water in that section of the creek. Here is the creek bed away from the dam site.

Monday, October 1st, 2007

I finally got around to running my matrix multiply microbenchmarks on Windows as well as Mac. Here’s the summary of times on Mac OS X and Windows XP on the same Mac Book Pro.

(Though not a big table, I’m using it to test out support for HTML 4 (ca. 1999) table elements like THEAD.)
