Talking about self-sufficent commits, just today I was asked about something I did a few months ago. Thanks to infrastructure as code and self-sufficent commits, it took me less than 2 minutes (including 2 logins) to find the commits that was in charge of the change why it was done and the related ticket, which triggered the whole action.
The first day it might be a bit tedious, but in the long term, it really pays off.
This is my personal microblog. It's filled with my fun, joy and silliness.
