I still do not understand why the mac web went absolutely NUTS here and for no reason whatsoever decided to start questioning whether or not the iBook was a "real" G4. Was it that surprising? Did people not believe that...

Uh, no. The problem is that the Athlon 64 / Opteron are NUMA systems, which work great for massive scalability but run into some bottlenecks on a 1-processor system - and some worse issues on 2P systems. One of the goals of system...

Mathematica has not yet been optimized for the G5 (or rather it has not yet been released in optimized form). The autovectorization capacity of IBM's compiler is still limited. The rest of those numbers are even more meaningless as...

Mike Z sucks. He's made negligible progress with the cell phone division and is a Galvin lackey. Let's hope the board brings in someone from the outside who is willing to shake up the Old Boys' Club.
