F8 2015 - Big Code: Developer Infrastructure at Facebook's Scale

What is it like to build mobile apps at Facebook? Join us as we tour the tool-chain that allows thousands of engineers to build apps faster - and for more platforms - than ever before.

For their developers they transition
A) from Git to Mercurial with a single repository for everything (future)
B) from IDE/Editors to Atom with Nuclide for all sources (ongoing, planned opensource)
C) from Buildbot to Sandcastle for better scaling (internal)

Must be fun... They seem to mature their development significantly.

I have so much more respect for Facebook than I used to. Good job guys!

Atom + Nuclide is extremely buggy at the moment. 100+% CPU usage on a new top spec iMac renders Atom really slow and at times unresponsive for minutes. Will we see any fixes soon?

"... so we measured. And it turns out, it takes three and a half minutes for a developer to start up Xcode and load Facebook for iOS, plus it's dependencies, and it's tests... that's not great and that's 3.5 minutes that the developer is not writing code." - Henry Ford

Doesn't git have sparse checkouts and shallow history? Why the switch to Mercurial?

[macohcoding]

sandcastle... what a name... what happens when the tide raises.... or when it rains to that castle?

I would like to start a little app to coordinate grocery-shopping with my flatmates and near neighbours.

Users can use the app to bring each other groceries to save time. Users should be able to type in when they have time to bring groceries for others. On the other hand, Users should be able to type in, which groceries at which time they want to be brought from other users.

So does anybody know what the fasted way to build such a system? Could it be done with facebook apps or would you recommend another way?

Your help is much appreciated and would help me, me neighbours (and much more people, if the system spreads) to save a lot of time and hassle!

cheers, kampfkegel

How come no one mentions this idea: Just stop coding. No infrastructure. Fast. simple
