And now, your moment of Zen
Due to some additions to the household (both structural and, er, genetic?) I've moved the home office into the 18th floor of a bonafide office building for a few months. That in itself was not really blog-worthy, but as I was leaving yesterday I noticed there were a couple birds on the ledge outside my window. At first I thought they were pigeons, but realized they were a bit bigger. Much bigger. It was actually two red-tailed hawks giving me the eye from the ledge outside my window.
I had just hit "Shutdown" on my pc, otherwise I would have had some amazing webcam footage. I was bummed to miss this once-in-a-blue-moon photo op, but seeing the pair base-jump off the 200ft ledge cheered me up.

Meiosys ...
is a company just purchased by IBM. They sell a product called MetaCluster, which is a virtualization tool that limits itself to taking a snapshot of system state so that it can be restarted and/or migrated to a new system (possible with a different CPU). VMWare's ESX server can do this, as can Xen (if not now, then soon IIRC), but by focusing just on persisting the systems they save a lot on overhead:
Because we provide a fine-grained virtualization at the application layer, our overhead is under 1%, compared to 15% to 40% overhead for some other technologies which enable mobility.
A lot of what open source databases don't have and commercial db's do is this type of clustering/ha. It will be interesting to see if projects like Xen can close the HA feature gap orthogonally for projects like MySQL and Postgresql.
