14: TIL database connections aren't cheap
A background job should be a function. So, putting more things in it is always a good idea! Sean announced that he shipped background jobs for crates.io. It's been in production for more than two weeks, and no issues have been reported. It's made life much easier because he no longer needs to spend time manually cleaning or cloning the index before changing a config bar. Now, he's working on librafying "Swirl." Also, Sam expressed frustration with his decision to use heredocs and block local variables in his Ruby autoformatter (Rubyfmt) - big mistake that caused big problems.
