I'm - happy? chuffed? not surprised? interested? - to see one of the last bastions of RISC fall down. Fujitsu has added an instruction prefix. Albeit a 32 bit instruction prefix, not an 8 bit prefix like the amd x86-64 REX byte. But same idea. New register for ... 24 Dec 2009 17:18

Speech vs pen vs keyboard vs ALPs pad Last Friday I posted to Facebook about how happy I was with my end of week Seattle to Portland commute. I was only person in the van, so I plugged in my headset mike and started dictating via Vista's built-in speech recognition. Sweet! Most productive 4 hour van ride I have yet had.

Xeon 3460 SMT power consumption and performance We recently got a new server that uses the Xeon 3460 (2.8GHz Lynnfield, like a Core i7-860). We use that with an Intel S3420GPLC server board. The other components relevant for power consumption are 1 2GB DDR3 ECC DIMM (the working configuration will have 2 4GB DIMMs, but that's only going to add a few W of power... 21 Dec 2009 15:49 |
