I do my best stuff midmorning and superlate at night, from 1 to 5 in the morning. Some people don't need sleep. I actually do need sleep. I just sleep all the time. I'll catch naps in the afternoon, or I'll take a 20-minute snooze in the office - just all the time. Our business is 24 hours. Our guys in Europe come online at midnight.

Jeffrey Zeldman had an astonishing ability to craft a seductive coolness using educated references, dry humor, and retro/organic imagery.

There are two main methodologies of open source development. There's the Apache model, which is design by committee - great for things like web servers. Then you have the benevolent dictator model. That's what Ubuntu is doing, with Mark Shuttleworth.
