November 27, 2025 Sub-Etha Software

Obviously, things done “today” can be quite different than how things were done 30 years ago, especially in regards to computers. Is it strange that out of all the places I’ve worked where I wrote code that only one of them had an actual “coding standard” we had to follow? …
