I just wrote a little script to give me some model geometry numbers. I'm sure others could use this, I wrote mine because all that exists online is half-ass Jskirpt pages that are covered in ads and offer a slightly different form of this calculation than I want.
Once upon a time I would've published this somewhere and let anyone else who wanted those numbers for a project of their own at least have a chance at finding and using my code for it.
Today, I don't have a place for that kind of thing (someone took offense to my presence last year and got me booted from several platforms). Even if I did, I wouldn't want to undertake the burden of having published something others might find useful, even in an utterly trivial context like "where do I put supports on a model railroad spiral ramp?"
Im too old, too ill, and too weird to get hired anywhere, so any code I write now is just for me. Its liberating. I no longer care about things like CamelCase vs under_score_debates and can set m y text lines at 300 char wide if i want to.
