Discussion on: Do software engineers at the largest tech companies (i.e. Google, Facebook, Apple, etc.) use Github for version control?

I've read about Facebook's use of Mercurial, so as of the last I've read they don't even use git. But I'd guess all of these companies use GitHub on some level. FB, for example does all of that open source stuff with GitHub, so I'd be curious about where they draw lines and choose where to do what.

Thanks so much for the Facebook intel. Interesting read for sure.

Didn't Facebook write the phabricator platform? It'd make sense for them to be using that.
