It’s definitely not required, but people can get a lot more done if they have some knowledge, whether from enthusiast or professional work.
Much more than just programming is useful, too - you learn a ton building structured information management systems, for example, so the barrier to working effectively with programmers and then learning to program yourself on the job is much lower.
Got it. That's rather lovely.
Thank you, that's very helpful. I've found the cepl videos instructive in a simlar area https://www.youtube.com/user/CBaggers/videos
I hadn't appreciated that level of thread isolation was possible in SBCL, but of course it makes sense. Presumably you had some kind of instrumentation to let you know if a stray syscall had slipped in?
This is fascinating. Did you come across any good resources to help learn how to optimise aggressively on SBCL, as you're describing?
