More from the vaults: In 2002, for Unix.se, I asked a number of developers/Unix people for screenshots of their desktops. Sort of like a crude usesthis.com-style thing. Here’s what I received.
The underlying OS is WNT 4, as might be guessed from the desktop display on the left. Almost all the space is taken up by a super-window running the drawterm program, an (approximate) analog of X server that’s connected to a Plan 9 CPU server (over ISDN; the server is at the main Bell Labs location, and I’m at home).
The biggest (pale yellow) window is a Plan 9 application called acme, which includes a mail utility showing your message. Smaller subwindows within the drawterm display are the mail-notifier program, and a shell window whose latest output is from our dictionary utility.
my desktop is pretty boring, since it consists of xterm windows to whatever unix system i am using at the moment. the machine itself is likely to be running some x-window server like exceed on some flavor of windows, though for many years i just used an x terminal.
