Please see a new version here. I am continuing to try to develop a practical engineering mathematics for operating system and other complex system code.
operating systems are harder than quantum physics
Went to hear Tilak Agerwala talk on the “Future of Data Centers” and was struck again by the way in which system developers and chip architects find solving problems like quantum power leakage and manufacturing devices with 100 angstrom feature
clouds versus pcs
George Gilder had an article in Wired on data centers as clouds. My instinct is to dismiss anything Gilder writes because of his track record of wacky ideas (e.g. feminism is destroying civilization and supply side economics makes sense). But,
linux kernel

we uh, threw those disk drives away, your honor.
“When workstations are at the end of their lifecycle and retired … the hard drives are generally sent offsite to another government entity for physical destruction,” the White House said in a sworn declaration filed with U.S. Magistrate Judge John
South by Southwest and Apple versus Dell
An old friend in the music business was visiting and we wandered around Austin’s gigantic South by Southwest music and film extravaganza and, of course, I was struck by the effects of Apple’s brilliant product design and marketing. IPods and
Sorcerers apprentice at ATT: Security and privacy and reliability collide again
AT&T considers reading all the packets that cross its lines. Quite an interesting proposal. Tim Wu’s take The prospect of AT&T, already accused of spying on our telephone calls, now scanning every e-mail and download for outlawed content is way
Yale Patt on Abstraction
Abstraction’s a good thing? Abstraction is a good thing if you don’t care about the performance of the underlying entities. You know, so many schools teach freshmen programming in Java. So what’s a data structure? Who cares? My hero is
