Answer A: Automated Git bisect
One great power of `git bisect`, and bisection search in general, is that automation is often not required. If you the bug loiters among 128 commits, you should only need seven tests to find it. It's great that one can automate this search. Sometimes it's even better that you don't need to.

Clear rules for how well-administered Mail Transport Agents should be configured is something that gmail (in my experience) has provided. That's a different thing,...

Comment Post #293715 Yes, I've been there. The errors from gmail were probably phased in gently over months at some point, but I didn't send often enough for that to be very clear to me. I got my SPF set up, and that makes me a better mail administrator. Importantly, it is **harder for the spammers to forge my address...

Comment Post #293715 They are certainly seem too big to have time to care about individuals' mail problems. Also being leaders on the tech adoption front, they seem to be more aggressive than other webmail providers in pushing for SPF adoption - and I think that is a positive thing.
