On “React Native for Android”

I think the best part of this article was the small link to the F8 2015 "Big Code" video 0 where they go into detail about switching from Git to Mercurial, building their own IDE around Atom, and detailing their continuous integration process. It's a long video but it's very watchable using the YouTube speed multiplier. :) 0 link to this video

On “Fighting spam with Haskell”

All correct, but I don't think Bryan O'Sullivan does much haskell these days. He's the manager of some sort of "Developer productivity" team. The Hack programming language came out of his team 1 (tho he wrote a blog post to contrast all the media coverage and say "my people did it, not me! 2); he spoke about his activity at the last F8 3. But he does teach Haskell at Facebook after work :) 4 1 link 2 link 3 link to this video 4 link EDIT: spelling

On “TTNT: Test This, Not That”

Facebook does this to scale their tests, you can hear Katie Coons talking about it in CI at the end of link to this video . There are also rules that say "if you changed this file, run all tests" for things like CI config and such. Also, the build tool Buck ( link ) enables this because it knows the graph and associates tests with the code they test...so you even get this test minimization locally as a developer (that is, outside CI) for free. I'm sure Bazel likely has a similar feature too.

On “Continuous Deployment at Instagram”

It's an internal system, but it was discussed at F8 last year. Here's the video ( link to this video ) and someone's notes on it ( link ).
