Some greatest hits:
- CoreAudio, Mac OS memory management, kernel in general, and many other decisions
- Google's internal dev tooling, Go, and Chrome (at least, in its day)
- C#, .NET, and Typescript (even Microsoft does good work)
One of the hallmarks of heroic engineering work is that everyone takes it for granted afterward. Open source browsers that work, audio that just works, successors to C/C++ with actual support and adoption, operating systems that respond gracefully under load, etc. ... none of these things were guaranteed, or directly aligned with short-term financial incentives. Now, we just assume they're a requirement.
Part of the "sensibility" I'm talking about is seeking to build things that are so boring and reliable that nobody notices them anymore.
