A lot of this is good sense for any application, and a lot of it is the stuff I’ve been advocating and implementing (where permitted) for years. I’m interested in the idea of environment variables instead of config files. I’ve always been uncomfortable with the ‘config not checked in’ idea, and I’ve suffered from the flaws, but I’m still not sure env vars are the answer. Given the quality of most of the rest of the site though, I’m prepared to look into it.
