Honestly I'm kinda down on most of FB's tech, but them pioneering Scuba was pretty sick. It has all the wide logging/apm/tracing/etc, and it's hard to describe how useful it is if you haven't seen it in action.
I'm with you on this one. Back in college I used to spend an absurd amount of time tinkering with XMonad, rainmeter, custom themes, but now my requirements for a computer are:
- it has a basic window manager (half screen left/right, full screen)
- it has emacs
- it has Firefox
- it has tmux
- (if the computer is really fancy) it has a calendar application
Software consultant, solution architect, solutions eng, all do what an "FDE" does without having the weirdly cringe palantir branding.
