When I started at my current employer (about 18 months ago), I got it in my head I should take advantage of their training budget and proximity to uWaterloo (like the kids are calling it now) and take a course.
For one reason or another (sanity, mostly; also scheduling), I wasn’t able to take the compilers course in my 4th year. Compilers is one of the big project courses. In terms of workload, it’s well behind real time (the train course) and graphics, but it’s still nothing to sneeze at.
When I was an undergrad, I think I would have probably preferred to take graphics. But as you get older, you mature. Or something. Yeah, graphics is cool and fun, but I think it would be a harder sell to get my employer to pay for it. Particularly when your employer has its own proprietary language to maintain.
For my part, I want to encourage people to make their own languages, because doing it makes you a world-class programmer. Seriously. Not just a better programmer, but a best programmer. I’ve said it before, and I’m sticking with it: having a deep understanding of compilers is what separates the wheat from the chaff. I say that without having the slightest frigging clue what “chaff” is, but let’s assume it’s some sort of inferior wheat substitute, possibly made from tofu. –Steve Yegge, The Next Big Language.
I don’t know if I’ll actually make my own language, or move to the compiler team at work, but I do know that understanding this stuff is really, really useful and fundamental to software development. There’s a lot of computer science-y stuff that’s not especially useful, but compilers are everywhere.
