The recovery went rather well yesterday, considering its extended length. Bob made some mysql tweaks to perhaps better use the memory on jocelyn (allow more protected space for query sorting, for example).

Vexing time-sinks: I spent 45 minutes this morning trying to figure out why one of the download servers (bane) was have autofs problems. Long story short: the route map was ever-so-slightly messed up so that it couldn't mount a single particular machine on a different subnet in our lab (why it needed to mount this machine was due to an "ls" command in a script - which by default displays color, so ls will traverse sym links to see if they are broken or not in order to select the proper color scheme, and in this case one sym link was on this remote machine). Also: the new donated server came with rails! As some of you know we have hilariously bad luck with rack rails of infinitely different (and useless) non standard sizes, and this time is no different. We needed to shrink the rail depth which should be easy. I did this to one and it fit! I did this to the other and, due to different screw hole location, it remains 1 cm too deep and unable to get any smaller. Ha ha ha (sob). Bottom line: useless rails, yet AGAIN.

But that's just a minor detail really - no need to rant and I don't want to seem ungrateful to our generous donor! We ended up putting the thing in the closet flat on top of the whole rack chassis. Works for me. We now have a new server called "thinman" (dual opteron, 16GB RAM) to help bolster the BOINC back-end! Woo-hoo! We'll update the server-wish-list with routers, servers, kvms, etc. soon.

Other vexing time-sink: Bogus news reports that we found a "mystery" signal should be summarily ignored. This was a gross misinterpretation by a reporter of an quick comment Dan made off the record about AstroPulse progress and recently published millisecond pulsar findings by another group. These are new stellar phenomena which are astronomically interesting (and AstroPulse hopes to find many of) but not ET. Sigh.

Here's hoping that Matt didn't really get "bloody" - sometimes those rails (particularly if you cut them!) have sharp edges on them.

I carry a scar on my right thumb from a rack-mount power supply that had such a sharp edge. (still have the p/s, too! - it puts out 12v at 25 Amps, NTM several other computer-type voltages at lower amperage)

hey sorry to hear about the rails, i just got a job helping set up a new schools network, looks like i get to play with racks now.

on a side note, what will that new server, "thinman", be running?

My SETI@home is still crunching away but the screensaver has changed to just the boinc logo and messing with preferences and updating it does not seem to help. I am not sure if this is an error on my end or you guys are in the process of updating the graphics or something but I am bit confused and I want my graphics back! Also I wish I could see where I rate compared to other people as far as credit goes, not that this is a compeition or anything but I wonder what kind of resources other people devote to this project respectfully.

Also, while you are in there you should also see a link to that person's computers. That gives you the a lot more information.

The Bad Astronomy Blog seems to have it right …
