I think this was linked on HN the other day, and it basically covers anyone using RHEL: https://boringtechnology.club/

God, I think you can tell the real engineers that have gone through the trial by fire and the ones that haven't simply by how much they agree with that presentation. At some point in your career, at 2AM when your debugging that fantastic new opensource library, for the 10th time, that you rewrote everything because it did exactly what you needed, and made you a hero for a week, you switch from gabbing the latest cool thing to picking those old technologies that everyone knows why they suck.

Because knowing why something sucks when you pick it, is more important than knowing why its good.

RHEL sucks because in 10 years you will be running some horrendously "outdated" software. Its fantastic because over those 10 years you will have made a pile of money selling your product and adding features rather than spending cycles being an upgrade monkey for things you didn't know you needed until someone sold them to you. And your customers, they don't care what OS your running as long as its reliable. Which is something RH provides in spades.
