National Semiconductor, which bought the line from Cyrix. I edited
several of the pin- and register-level manuals for various chips for
them more than ten years ago, and updates of my work are still online
on the AMD Web site. OLPC has educated AMD on how to use the
power-management registers to do things that nobody previously knew
were possible.

I am delighted that this premature obituary also turns out to be
greatly exaggerated.

Marvell has bought XScale from Intel. That may be the principal
alternative. The Encore Mobilis being bought by Brazil for its schools
uses an XScale processor and MontaVista Linux, so Sugar Labs should be
working on an XScale port of Sugar soon.

Alan Kay loves to ask how Doug Engelbart and his team managed to
shoehorn all of the Online System (NLS) in The Mother of All Demos
into 192K in 1968.This included realtime videoconferencing and
instantaneous, seamless crash recovery. People come up with all sorts
of technical theories, but Alan's answer is, "Because they wanted to
badly enough."

Silent Thunder (默雷/धर्ममेघशब्दगर्ज/دھرممیگھشبدگر ج) is my name
And Children are my nation.
The Cosmos is my dwelling place, The Truth my destination.
