Happy Cavity Day! (Oct 31 2007)

Happy Halloween! We celebrated here in the Bay Area by having a 5.6 earthquake last night. No big shakes (ha ha) considering the relatively high magnitude. Anybody thinking Californians are crazy for living in such a seismic zone should remember the top two recorded earthquakes in the contiguous US were both in Missouri. I also grew up across the river from the Indian Point nuclear reactor, just outside NYC, which lies right next to a very active fault. Anyway...

Somebody complained about the weekly outage time notices on the web being off from reality. They are semi-automated, and one mechanism was created during PST and the other during PDT. As well, we haven't been sticking to exact times lately as we've come to rely heavily on BOINC's fault tolerance, i.e. if it's convenient to bring down servers a half hour early then it's no big deal - the clients should fail to connect and back off gracefully. So those messages are under the category of "vaguely informative" or "better than nothing" but at some point I'll tighten up their accuracy.

Jeff and I spent a chunk of time finally getting some reasonable load balancing to work such that we don't have to worry about feeder mod polarity issues (see older tech notes - basically round robin DNS doesn't work as expected and one server runs out of work faster than the other). We were lagging on this as actual requester IPs weren't showing up in the apache logs as the proxy was in the way. We discovered "mod_extract_forwarded" but we were using the wonderfully simple and effective "balance" utility which doesn't pass the expected "X-Forwarded-For" header to this module. Then I discovered "pound" which is like "balance" but does add the right headers to make this happen. Long story short: we're currently up with hopefully more equitable load balancing.

Outside of that: messing around with beta splitters again this morning (the beta project is mostly Eric's domain which I try to avoid as much as possible) to keep work generation going and test out the new splitter compile. And working on skymap stuff for public web consumption.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind

I just hope that we can keep phoenix at bay after we pass them. I've never seen us at 171k before, this is great!

Thanks for the stats, Rattledagger! :D

Really nice production - probably a result of the tuesday - outage and the preparations for the Gauntlet race ... :)
