Not much going on (SETI@home-wise) over the weekend. The fallout from those traffic woes over a week ago are pretty much all behind us (I think completely after we do the database compression tomorrow). The average temperature in the server closet has risen slightly, but we think this is mostly a function of current weather (it seems that during rainy/foggy periods the air conditioner is less efficient).

I did get another server online - something donated by Intel a while ago but only now found the time to set it up, add more memory, etc. It's going to mostly used as a compute server for Eric's hydrogen study project, which is good for SETI as that means his IDL processes won't be competing with our NTPCkr/radar blanking tests.

We continue to have raw data drive enclosure problems. This time the set down at Arecibo is getting funky. Very hard to debug remotely.

Thanks for the update as ever Matt.

Yes, the latent heat of vaporisation is what's causing the extra load on the air conditioner. At 640 calories per gram of water, it's much higher than what's needed to chill the air.
