Coding on tealeaves today was mostly pulling interesting bits out of ssh keys. Misc things discovered

I also was struggling with tooling, which I guess is the name of the game in lower-level systems programming, and I ended up writing a little rust unix utility to hard wrap files at 32 characters after stripping whitespace so I can pipe hex dumps into it and get nice column widths. That was actually fairly fast and easy to do so for simple things it feels like once you're over the learning curve rust might actually deliver on its promise of scripting language ease with no-compromise performance at runtime.

Later I paired with one of the RC mini-batchers who taught me about fold -w 32 which is a standard unix tool that can do most of the same thing.
