Er, an article in last Friday's Seattle Times, sourced from the AP,
said that there are 4,296 megawatts installed in Texas alone, and a map
shows that Washington, California, Colorado, Minnesota, and Iowa all
have more than 1000 megawatts installed. And there are plans in Texas
for 18,000 megawatts. And the power lines to carry it.

Nope. Psychology and Political Science. (One trip out to the University
of Washington main library, I searched the stacks for his thesis, but
it wasn't there).

It was probably on the Epson QX-10 and a dig at Valdocs.
I liked some of his SciFi, but his technical commentary always
left me cold.

Jerry Pournell used to write a column for BYTE, and he was a whining
