  • Facebook does not use Git due to scale issues with their large monorepo, instead opting for Mercurial.
  • Mercurial may be a better option for large monorepos, but Git has made improvements to support them better.
  • Despite some drawbacks, Git usage remains dominant with 93.87% share, due to familiarity, additional tools, and industry trends.

Speaking from my own experience and a few other seniors I work with, you try to recreate solutions you like at those smaller shops. It may not be identical, but you know what's possible.

I came into a company that didn't have a system to manage errors. At my old job, errors would get grouped automatically and work can be prioritized through the groupings. The new company only handled errors when they saw it, by word of mouth.

Immediately went to work setting up a similar system.

There’s also a whole industry of ex-Googlers reimplementing Google tooling as SaaS services to sell to other ex-Googlers at other companies.

There’s even a lookup table: https://github.com/jhuangtw/xg2xg

(some of those are open source projects, some are SaaS services)
