Not posted anything for a while, I kind of forgot/gave up on blogger for a bit. Might start using it again now though. Anyway, here
is an interview with Rich Wareham, who wrote the very handy and open source Desktop Manager
for Mac OSX, which adds UNIX-style virtual desktops to the Mac. I like it a lot.
At one point in the interview he describes the UI on the computer as doing "impedance matching" between the way the computer works and the way the users think. I think that's a cool description - the GUI becomes like a DI box or something. :)
