Photoworld · Here’s some reportage from the photoenthusiast side of the brain, including a shot by an actual real professional (and the difference shows), Ricoh rumblings, calibration, conversation, pictures by four different cameras, and two pictures of camera gear. I can gang together nearly-unrelated topics in a great big post like this because photo-hounds will read all of it and nobody else will read any; so efficiency is maximized ...

Slow Bonnie · I’ve been noticing that it takes longer and longer to get a meaningful Bonnie run. To make sure you’ve busted the filesystem caching and are actually doing I/O, you need to use a test file two or three times the size of system memory. Which can easily get into a couple of hundred gigs on a serious server these days. And while I/O has been getting faster, it still takes a while to process that much data; and Bonnie does it five times. So, the ratio that governs Bonnie testing time is something like memory-size over I/O-performance. Thus we observe that, proportionately, memory size has grown faster than I/O speed. Thus, memcached and friends.
