While I agree with having an immutable arch is preferable but in some cases it's not viable. In one of our projects we re-use the instances like in the article since we deploy multiple times an hour. In AWS you are billed for each started hour which in this case would mean that we would pay a lot extra if we created new instances for each deploy.
That's totally unrealistic. Often it's not the dev. that changes his mind, but the client. And since they have the $$$ you will be "undoing" previous work.
This so much. People consistently complain about PHPs' stdlib and how the naming and parameter order are not streamlined. Git is very similar to PHP in this case. It's not something that's going to keep people from using it but it is one of those warts that people just have accepted.
The first comment (as of right now) makes me sick to my stomach:
"Why are we providing a platform for families of terrorists to advocate against American national interests? They should have considered the consequences of targeting the United States and its citizens with violence before they walked down that path.
Our intelligence services and armed forces have done a commendable job keeping Americans safe. I thank them for their service, and for keeping my family safe.
I have no time or desire to listen to this sorry speech about human and civil rights from someone who did not stop his son from advocating violence."
