Be kind (2016)
Disappointed that one of the lessons was not “don’t deploy on Friday and then immediately run out the door.”  I know most of you will say that that shouldn’t be an issue if you have proper tests, devops, etc., but this type of thing is the reason that Ops usually controls the releases. Yes, I know, Ops is obsolete and can go suck a lemon, but it’s stuff like this that shows the wisdom of the older ways.<p>So yeah, be nice to Ops too, because they actually have experience in stuff like this and one weekend of downtime is not an appropriate price to pay for every developer to learn a lesson.
