  3. It would be nice to have a Github repo where you can browse the history like for Unix at https://github.com/dspinellis/unix-history-repo . Not going to happen, of course.

  17. https://github.com/dspinellis/unix-history-repo is a project that attempts to document Unix from its very first line all the way up to FreeBSDs HEAD (at least whenever it's imported, which might only be once a year). There's even a gource…
