The whole point of Scrum is to use the retrospective to stop doing what doesn’t work and start doing what does.

That is only something useful if you can use the retrospective to through out Scrum. Otherwise it is yet another Scrum timewaster.

you should keep the rituals that help you work better and discard the rest.

For those using Scrum, that means keep backlog list and discard everything else.

Unix loves to fork processes. So you get lots and lots of processes.

Well that sucks. At least Bill Joy, creator of VI, is still with us.
