I've been meaning to pick up a breathalyzer.. but that's just asking for trouble if you've ever read that Tucker Max post about them.
I've experienced this, but there's a problem. I don't remember where I read it, but there's a programming rule I picked up somewhere. It's something along the lines of, "Debugging is harder than programming, so if you program the cleverest code you can, you won't be able to debug it." I've written killer code while moderately drunk, but if you need to modify or fix any, you may as well just do a rewrite. It'll save time.
That's nonsense, though. Debugging is much, much easier than programming.
Debugging is tedious, non-determinate, and requires a lot of knowledge recall. Not usually "requiring creativity or higher level thought"
Contradiction, there. If you can't modify or fix the code, it's not "killer".
It might be an overloaded "killer", with both the idiomatic and literal senses in mind.
