The Mandate Of Heaven

Rode Jacobsburg last night on the singlespeed, had the place pretty much to myself though Lee rode in on his motorcycle to say hi. He'd taken the day off & did a bike ride earlier in the afternoon -- the bum! Saw a few Blue Mtn Ski Club riders out there, but the parking lot was almost empty (rather than the usual filled-to-capacity Thursday scene), and none of the usual crew was there.
After that was a Team in Training fundraiser at Which Brew: one of Margarita's friends/co-workers will be running a marathon in San Francisco, in memory of another co-worker who died of lymphoma. They had arranged to have some friend's band play at WB, and also to have raffles with cash and merchandise prizes. I missed the raffles, but gave a $15 donation and got a soft-pack cooler -- sweet!
Geeking Out, or, Evolution in (Virtual) Action: I took a grad-level "Computer-Aided Engineering" course in college, and one of my favorite parts was the section on nonlinear optimization and mathematical programming. I still keep my dilettante's eye on the field, and a few years ago ran into a really cool new technique called "genetic algorithms," which use data structures and mechanisms analogous to genes, mutation etc in biological systems, to allow evolutionary forces to select the optimum design. I got some killer C programs from a Navy research site, but here is a good introductory page.
Slipping is Crash's Law: The old Chinese Empire used to go through an approximately 300-year dynastic cycle (on average), ending with stagnation, revolution and the establishment of a new dynasty. The cycle was pretty much caused by the rules of inheritance, which slowly screwed up the system until it was paralyzed -- then the society rebooted, land and wealth were redistributed and the cycle started again but the Chinese explanation was that the previous dynasty lost "the mandate of heaven;" the divine universal force showing its displeasure and withdrawal of support through natural disasters etc. The number of disasters per year didn't actually rise, but what happened was that the Imperial ability (or will) to prepare for and ameliorate them had collapsed. Sound familiar?
UPDATE: forgot to post this Friday.
