Now we can have a willy-waving contest!

I bet I'm an older fart than you are! nya-nya-nya-naaaaaa! <sung to the

Nah, the specs need replacing. There are some funky tri-focal jobs that
distort my depth vision, and I have to turn my head straight to look at
anything (no more looking out of the corner of my eyes). Makes
motorcycle riding a real pain

I'm waiting for our approved hardware suppliers to come out with a range
of 1U pizza box ARM servers that management will buy into. But first
they need to lose the idea that virtualization is the go-fast solution
for anything.

Almost every single machine I run except the database servers will fly
along on ARM. I'm especially eager to see what ARM does with high
traffic DNS caches. Intuition tells me they will handle 20,000
queries/sec without breaking a sweat and the Gig ethernet will max out
long before the cpu does; all at 1/4 of the price
