There's nothing to gain in punching down

They made a mistake and are sharing it for the whole word to see in order to help others avoid making it.

It's brave.

Unlike punching down.

This has nothing about punching down. Writing a blog about this basic mistake, and presenting as advice shows a strong lack of self awareness. Its like when Google bought thousands of servers without ECC memory, but felt they were so smart they could not resist telling the world how bad that was and writing a paper about it...Or they could have hired some real hardware engineers from IBM or Sun...

		> Writing a blog about this basic mistake, and presenting as advice shows a strong lack of self awareness. You realize they didn’t ask you to read their article right? They didn’t put it on your fridge or in your sandwich. Policing who writes what honest personal experience on the Internet is not a job that needs doing. But if you do feel the need to police, don’t critique the writer, but HN for letting interested readers upvote the article here, where it is of course, strictly required reading. I mean, drill down to the real perpetrators of this important “problem”!
