To answer Partha's question -- though the answer can be found elsewhere now -- it's not just Partha's computer. YACC, who provides our commenting service, is down, and will be down through the weekend. I would do something about substituting another service for YACC, but we're planning some big changes behind the scenes which will be unveiled shortly and make it unnecessary, so I see no great urgency to act right now. So if you want to complain about something Partha wrote (and who doesn't?) you'll have to respond to us via email.
