Also forgot the +- thingy 🙄

Python (lots during time at Mozilla and a little bit now) +

@GeePawHill I try and learn a new language every year even if I keep coming back to Ruby for day to day. Too many to list but I’ll hit the highlights of the ones I feel like have made me a better dev overall.

@GeePawHill

++ awk
++ C
++ C++

+ python

I might be missing a couple.

I still write the occasional python script. The latest was to add an image to the fore-edge (opposite the spine) of a book by printing a slice on the edge of each page of the pdf.

@GeePawHill As I can reconstruct it and not counting 'one course in university':

-Concurrent Euclid (UofT research language)
+C and 68K assembler

more or less at the same time:

@GeePawHill For work, I came up with the following list. I've also toyed briefly with some others, but not seriously enough to add them to the list.

Also, this list is not strictly chronological. There's too many loopbacks to do that.

I recently wrote a post about my career trajectory (https://hectorcorrea.com/blog/2026-01-12/career-in-software-development) and one of the things I highlighted for newcomers was the discrepancy in the tech stack at school vs tech stack at work and that in the long run it does not matter that much because our tech stack will eventually evolve no matter where we start.

@GeePawHill
++ BASIC (HP 2100 & Apple dialects)

- Prolog
++ Java (longest 'in anger')

Those represent use within my work (though not always for end-product; and I've probably forgotten some). [I've a particular personal interest in languages, so I've also learned the basics of many others along the way.]

@GeePawHill

1/2
Started as scientist programmer, then paid developer/tech Architect and now UX Designer/Architect. I’ve always taken a “toolbox approach” to digital dev tools-
1. Know at least 2 tools that do the same job, pick your preferred & master it.
2. Check out new variants & update “toolbox” accordingly.
3. Regularly practice tasks, methods & techniques.
4. Regularly share, explain and teach tasks, methods & techniques.
5. Pick the right tool for the job, not default to your preferred.

I remember reading a book about OO programming in the 90s that was about message passing

The only languages I learned in a formal academic setting were FORTRAN, Pascal, and VAX assembly. I have two degrees in nuclear engineering and none in computer science.

Of all those, Perl 5 and Modern Fortran are the least awful or at least where I felt most comfortable. I wouldn't choose Perl for a modern project. Too much I work on ought to be written in Modern Fortran instead of Python. APL is alternately genius and demented - fascinating language! I first encountered Javascript in 1997-8 in the 2.0 browser era - all I remember was it was hideous and broken and I disavow any knowledge of it (same for anything related to Oracle and RMAN). Lisp & Scheme elude me, SICM is impenetrable, dense, and unmemorable - none of it sticks. I have a wall of computer language texts - Prolog, COBOL, MUMPS, SNOBOL4, ALGOL, C++, D, Forth, Julia, Fortran texts spanning 60 years including F, along with fictional teaching languages like MIX and TYDAC. Occasionally I'll dig into an older language (I need to get back to Forth and dig more into 6502 assembly. Maybe add JOVIAL).
