Oracle To Buy Sun For Approximately $7.4 Billion – Hold On To Your Hats .
If the past few years of history with InnoDB are any indication this is terrible news for MySQL. Percona stepped up to solve that with XtraDB, now I’m hoping they take the lead on drizzle (which may mean forking and staff pilfering) and give us the drizzle+xtradb combo that we’d all love to see.
I wonder what they’d call it… PercizzleDB?

Doesn’t show my personal favorite though, 99.95, or 20-minutes/month. Its nice to work in the media industry.
Over the last two weeks I’ve had a number of confrence calls with my Dell sales rep and some engineers about the new Xeon 5500 / “Nehalem” based blade servers, and specifically over the memory configurations thereof. I have learned one thing for certain, this shit is impossible to explain without pictures.
The good news is, eventually I stumbeled across this great writeup with pictures on the Dell TechCenter Wiki: Nehalem and Memory Configurations
However its still a lot of words, and requires some intepretation to adapt to the M610, so with that in mind here is my explanation in ms-paint form:
Read the linked article for why, but the short of it is:
6×8GB for 48GB is probably the sweet spot. It gives the best memory bandwidth performance and a 6GB-per-core ratio thats a good midrange for virtualization.
NOTE: HUGE CAVEAT! – 8GB sticks aren’t available for purchase yet. So if you plan on running vmware on these, you have a two month wait ahead of you.

Just had to do a “live” default route cutover and while I was mostly sure it was gonna work its nice to have it definatively proven now. You can add the second default gateway, then remove the first, so there’s never not a default route. I’m not sure which one it kept using while they were both there, or if it per-packet loadbalances or what, but my ssh sessions didn’t even hiccup so at the very least it won’t knock you offline or interupt connections. Of course this is assuming your upstream devices aren’t doing any nat/firewall stuff to complicate things.
