There are also a whole bunch of languages for:

- Describing levels in video games, which are primarily data with code mixed in

- Describing transformations of different sorts (e.g. the types of languages used in compilers for specifying a programming language parser, and then optimizations)

- Defining hardware (analogues to Spice, Verilog, and VHDL). Hardware can also include mechanical objects, as well more broadly, wetware (e.g. custom bacteria, a la Ginko Bioworks)

- Run on custom hardware (e.g. SIMD and MIMD platforms, similar to GPGPU)

- Are primarily mathematical (e.g. for describing control systems, neural network architectures, etc.)

... and so on.

Not all of this is a DOD/medical mess. A lot of DSLs are REALLY REALLY FUN.

My guess based in my experience would a MUMPS developer for someone like Epic or Meditech. That code gives me nightmares whenever I see it.

Still can barely believe MUMPS is real tbh, first saw it on TDWTF and I thought it was a joke at first.

Coming from today's world, sure. But in 1966, a language with a built-in database was a godsend and there were no standard language conventions to adopt (C was still several years away and only COBOL and Fortran were in wide use).

What, like $$foo(3,4,@bar,"baz")?

A brainfuck developer?

Writing DSLs is not uncommon among Lisp developers.

im guessing a very loyal employee to an enterprise company outside of tech - probably logistics

Retired? Or in Academia?

DoD?

The name is Den. Snow Den.
