Hello again. So it seems we have the lab-wide (actually hill-wide) power issues behind us. The bottom line is the short circuit (in a major underground line that brings power to several buildings) was found, and fixed, and we are back in action. That sure ate up a lot of our time. This is also proposal season, so I've been lost in some paperwork as well.

Some minor issues also caused some bumps in the road. Dan's new-ish desktop has been crashing at random. I'm still trying to diagnose that. This would normally be no problem except as it happened I was keeping a database on that system which helped serve the seti.berkeley.edu web site. So for a couple days that site was getting all messed up until I finally moved that database elsewhere. The machine is still crashing, I have no idea why (it isn't temperature - I'm guessing it's a software issue but not sure what). At least the seti.berkeley.edu web site is stable.

Also had one, maybe two, disk failures in synergy. Not that big a deal since the RAID protected the data thus far but I'll need to procure some disk replacements soon for that. They're 1TB SAS drives, so we don't have any spares kicking around (unlike SATA drives, of which we have plenty at the moment).

Outside of that I've been helping Andrew sort out and archive 13TB of data he recently collected at Green Bank, while using paddym as temporary storage for that. Once we're done with that I can then reconfigure paddym and we can start making it a master science database!

As always, thanks for the news.

An speaking of random re-boots, a somewhat newish machine of mine is also giving me fits and it isn't temperature or software.

Thanks for the update Matt,

Have you tried substituting the RAM in dan's desktop?

You have already tried these, but in order.

Bad Driver.
Failing memory.
Failing Power Supply (possibly fried by a spike from the recent power problems).
Failing video card.
