We're about to enter the first of two long holiday weekends. I'm not going anywhere - I'll be around checking in from time to time. To reduce the impact of unexpected problems I reverted the web servers back to round-robin'ing between kosh, penguin, and the new bane, and also (thanks to the recent increase in storage capacity) doubled the size of our ready-to-send queue. That should fill up nicely this afternoon and give us a happy, healthy cushion.

There was a blip yesterday afternoon due to our daily "cleanup" query to revalidate workunits that failed validation due to some transient error. Such a query hogs database resources and can cause a dip of arbitrary size in our upload/download I/O. We made an optimization this morning to hopefully mitigate such impacts in the future.

Eric discovered yesterday that we were actually precessing our multi-beam data twice. Not a big deal as it's easy to correct, and we would have discovered this immediately once the nitpicker got rolling, but it's better we discovered this sooner than later as cleanup will be faster. Pretty much we just have to determine which signals in our database were found via the multi-beam clients (as opposed to the classic/enhanced clients) and unprecess them. (What is precessing?)

Hah! Extra wobble! No wonder we're getting storms in Australia in the middle of summer! Keep it up we need the water! :D

Happy Holidays to you all at Berkley!

I wish someone would come up with a method of easy snow removal via a computer controlled snow shovel/blower. We got way too much snow up here near Montreal, it's not nice shoveling it anymore.

Enjoy the relative California warmth and hope everything runs smoothly over the holidays.

Will 2008 be the year when E.T phones earth? who knows but one thing is for sure, you guys need a decent break!
