Joel Spolsky – The new Fog Creek office:

"Private offices with doors that close prevent programmers from interruptions allowing them to concentrate on code without being forced to stop and listen to every interesting conversation in the room.

[…] Long, straight desks include a motorized height-adjustable work surface for maximal ergonomics and comfort, and so you can stand up for part of the day if you want. Standard 30” monitors. Desks are straight instead of L-shaped to make pair programming and code reviews more comfortable. There are 20 electrical outlets behind every desk and most developers have small hubs for extra computers. Our standard-issue chair is the Herman Miller Aeron."
