The problem with Cargo is it only builds rust. I agree it's the best language-specific build tool, but I love the monorepo pattern and future proofing insurances that modern language agnostic build systems like Bazel enable / provide.
Yep I bet she could - don't let the way I described my use of it as a 'poweruser' (via the cli) scare you off...the browser extensions are very user friendly, just ctrl-shift-L and fill out a few inputs
Lesspass generates reproducible unique passwords from inputs (username, domain, masterpassword). It works without an internet connection and is open source. You only need their cloud storage if you want to backup metadata about the password requirements for specific sites (i.e, no special chars allowed by foo.com, bar.com requires a capital letter and a number, etc.) This metadata can also be stored locally. The command line utility is great, they also offer Mozilla / chrome extensions and mobile apps. I bash alias the command line command to copy the password into clipboard so when I navigate to a site on my laptop, I run genp chase or genp amazon and quickly have the pw ready to go in my clipboard. The apps / extensions and even the cli uses emojis as a visual cue to let you know you typed in the correct masterpassword (since it's masked)
