So I was reading up a little about Dtrace, and got digging around
Sun's web page a little. Eventually I ended up googling for the names
of the folks behind it. Got amused when I found one of the
'dtrace three', Bryan Cantrill was the same person in
this old thread.
Davem's follow-up
was equally as amusing. There's even an insight from a

pre-gnome Miguel in there. (Though he doesn't say 'dude' once, which
is somewhat suspicious).

My memory upgrade for my Compaq Evo turned up. With 768MB, its a lot
more snappy than it was with 256. Now things don't quite grind
the disk so much when I'm really pushing it.

Fallout from the kernel updates for FC2/FC3 doesn't seem too bad.
A few indications that SATA is broken for some users.
That really needs fixing, so it's possible there'll be another
update out in a day or two.
