> and encouraging people to be discontent with multi-minute long build-test-debug (BTD) loop.

The ole eyebrow started twitching when I read this. I once had a 6 month contract with a RoR shop where they had such bad performance issues they started developing in production mode so it wouldn't reload everything constantly. This allowed you to make some changes quickly, but 90% of everything required you to restart the web server and it literally took minutes for it to load everything. They had close to 200 rubygems, and I've always guessed that was the core of the issue.

When I suggested we need to fix that issue, the senior did-an-internship-here-last-summer developer got extremely passive aggressive with me (I didn't renew that contract). This guy thought he was amazing, I remember him arguing with me about a bug where they were storing decimal numbers as float in MySQL. I seriously had a 30 minute long conversation where he told me repeatedly I was wrong until I finally got exasperated, made the changes, and it fixed the bug. The guy was couldn't believe it fixed the issue and spent another couple of hours looking for why I was wrong.

I've never touched RoR again, that experience was horrific.

Sometimes you can't help the slowness, but I know I seriously dislike header-only libraries in C++ specifically because of their effect on the BTD loop. I have no idea how people can tolerate working like that, it's a slow hell for me.
