That is interesting. I wondering how the 15 people that had created the ~600K c++ codebase I’m talking about compares to the FB headcount on android Messanger, does anyone know how big that team is? loc/head is a curious measure.

Regardless it’s a bit concerning that it takes 10M loc for a messaging app.

Does lines of code have any meaningful use as a statistic when I can simply include a bunch of libraries and headers to inflate it?

Not forgetting of course that Twitter almost certainly uses several languages on the backend, and has it entwined in their infrastructure. As TFA says:

"One former Tesla engineer, who spoke on the condition of anonymity to candidly describe the matter but was not involved, said Tesla engineers would have trouble capably assessing Twitter’s code. Distributed systems, the large-scale and spread-out network that Twitter is composed of, are not the automaker’s specialty, the person said."

9M of that is probably localization files, 500k licenses

:P

A lot of the android code at Facebook is auto generated boiler plate.
