Technical news and SETI@home daily stats for 23.03.2007.

[Rattledagger]

Yesterday afternoon we had to reboot kryten/penguin to flush their pipes. Sigh. Bruno is well on its way towards becoming a full fledged upload server, but the sooner we get bruno to be the download server the better. The major gating item on that is the need for a new 24 port gigabit switch for our closet. Long story.

Meanwhile many clients are still connecting to kryten for uploads. This is thanks to the wacky unpredictable internet while trickles out DNS changes at surprisingly slow rates. While diagnosing this I wrote a script to show me a sample of the most recent client version types to connect to our servers. I then made it into a web page (there's a link on the server status page as well). Yup - we're dominated by Windows, but they're not to blame for any DNS-related issues. Anyway kryten will probably completely free of upload traffic within a week or so.

I just heard cheers from Jeff's desk - he compiled an assimilator on bruno. He's now working on the validator - linking issues.

Bob worked some magic and got sidious back on track today without having to do a full restore. So it's acting as a replica again. We're still not exactly sure why, but we found the MYD files zeroed out within the past week (and was only exercised upon stopping/restarting the database on Tuesday). Some research shows this may be a bug when replicating a mysql version 4.1 database to version 5.0, which is exactly what we're doing. We're planning on upgrading the 4.1 soon, so maybe this problem will disappear.

Oh yeah - there was a network blip this morning around 6am. Not us. It was campus working routers further up the pike. And we had a minor blip around noon. That was me screwing around trying to get the beta project working again. I think Eric is ironing out the last remaining details on that as I type.

There is some concern that results got munged during all this switching around. Probably so, and we're sorry if this happened to you. We'll try to clean it up and get people their credit as best we can.

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...

No, it's not "sudden", they'll been slowly working their way up from #49 at 01.04.2006, when their predicted overtake was 761 days...
