This is why Spack was created:
> Spack is a package management tool designed to support multiple versions and configurations of software on a wide variety of platforms and environments. It was designed for large supercomputing centers, where many users and application teams share common installations of software on clusters with exotic architectures, using libraries that do not have a standard ABI. Spack is non-destructive: installing a new version does not break existing installations, so many configurations can coexist on the same system.

> Spack is a package manager for supercomputers, Linux, and macOS. It makes installing scientific software easy. Spack isn’t tied to a particular language; you can build a software stack in Python or R, link to libraries written in C, C++, or Fortran, and easily swap compilers or target specific microarchitectures.

Very similar to (home)brew, MacPorts, etc, with more of a focus on HPC so you can have multiple versions of a particular piece of software, made with different compiles and linked against different library version.
It’s worth noting that one of the paper’s authors is Todd Gamblin, the Spack project lead.
ajdecon commented on Ask HN: Is there any book like: from ohms law to 8 bit computer · Posted by u/deepbluesome
“The Elements of Computing Systems”, by Nisan and Schocken, starts at logic gates and works up to a functional computer that can play Tetris. So not quite Ohm’s Law, but close.

I’ve seen most of these recommendations before, but the “mic-drowning case” to muffle room audio is new to me. Certainly makes sense, but are there any common commercial phone cases that advertise this feature?
I was already remote, but I’m moving from Seattle to Denver.
Combination of family and a more favorable climate. The somewhat lower cost of living doesn’t hurt, but it’s not like Denver is cheap.

On mentors, is it true that you’d be better off at a big company?
I’ve been looking for good mentors for years but have been stuck at startups. I worry that mentorship will escape me if I get on the wrong team at FAANG. I feel like this is the #1 thing limiting in my career. (Good guidance) I can’t imagine having a mentor who isn’t on my team who would actually want to mentor me.
Many large companies have structured mentorship programs, but this is mostly for onboarding. Your mentor will help you learn about the company itself, e.g. all the different internal practices, tooling, teams, etc. (This is nothing to sneeze at, given how big these orgs can be!) It may include some more general career development but this is often aimed at early-career folks.
For more general mentorship, especially as your career develops, it’s the same as anywhere, you have to find someone you get along with and who can help you learn. The advantage at a big company is that there’s a huge pool of potential mentors, and you can see their calendars and coordinate more easily than if you were hunting in the community. :)
While the underlying model is certainly different, and my understanding is that current LLMs don’t learn “live”, the principle seems worth keeping in mind.
