This doesn't have all architectures, but I care about all
architectures here in some capacity. In particular, I personally own
computers that have can run NetBSD that are amd64, aarch64, i386,
sparc64, and powerpc. It's also trivial to emulate m68k and vax.

I find it rather interesting that the major scripting languages are
the easiest to get running on most architectures.

As per the source, any base Unix language (C, sh, awk, etc.), C++,
and Lua are available on all architectures due to being in NetBSD's
base system.

If a language supports NetBSD/vax, it belongs on my toolbelt. I have
some degree of familiarity with all languages NetBSD/vax supports.

If it supports NetBSD/sparc64, it also probably belongs in my
toolbelt. I've never really used Fortran or OCaml (though with the
latter I have touched F# a bit, and I find ML family languages to be
aesthetically pleasing), but it does interest me.

In particular, this document is probably the best argument for me to
seriously get into Rust or OCaml.
