How Precision Time Protocol is being deployed at Meta

Why do so many tech companies seem to be releasing “secret sauce” for free lately? I see a lot of posts lately detailing how inner production systems work at large companies, and while I’m grateful, I’m curious why the higher ups think it’s worthwhile to release this information.

It's an effective marketing campaign for "you should work here" - VERY effective.

And lots of this stuff is NOT secret sauce, it's basic business building-blocks that they need. It's not the advertising formulas.

I'm sure FAANG is very VERY happy that they can just run Linux everywhere and don't have to pay Sun or Microsoft a massive per-CPU fee for everything they do.

I think you'd normally be right, but Meta just laid off 10k+ people, and is currently in a company wide hiring freeze until at least Q1 of 2023. Much of the rest of FAANG is either doing one or both as well.

In Meta's case, they fired a lot of "boot campers" as well, some only a few days into their job and before they had a team. Some returning interns even had their offers rescinded.

Not to sound cynical, but this article feels more like "let us release this to show impact and keep our jobs." Or damage control for their engineering hiring image.
