I imagine in any situation you have an ELF binary you need to analyse but have no source for it. Reverse-engineering and forensics come to mind.

This is anecdotal, but when I don't floss my teeth hurt.

Probably poor technique. When the oral hygienist flosses my teeth it doesn't hurt at all but I can't replicate the pain free flossing at home.

You _can_ use the GNU Autotools on Windows, though you need a shell installed (and a vaguely sane POSIX environment). CMake does a good job targeting a bunch of environments, including Windows.

I'm not really sure how to benchmark it myself, those are from 2012 and I'm sure things have improved since then.

True, but they're one of a few investigating new ways of launching rockets without having to go through the thick lower atmosphere and from stationary. Everything they're learning could be used to build a launch system that drops rockets from very high in the atmosphere -- imagine how much more efficient they'll be.
