Damn, how did you survive the 80s/90s!

(I think I can guess the answer).

Things could always be better, but at least it's routine now for stuff like Swift, GoLang, Rust, Protobufs, Cassandra, etc. to get built for internal use and then shared with the world. A far cry from software's dark ages.

Using Cython means you don't/can't use Pypy? Was that something you considered, e.g. with psycopg2cffi or a pure-python driver? It seems to be the defacto performant runtime for Python, and since performance is something you guys obviously care a lot about, I'm surprised it hasn't been mentioned in this thread.

Very excited to try out your code - thanks for sharing it.

Consider the broad category of physical pursuits that capture your complete attention. I don't include cycling, running or lifting in this category because it's easy to stew about problems at work/home while you're engaged in those pursuits.

Mountain biking is a great example - at a sufficient level of difficulty, it really pushes everything else out of your brain and forces you to be in the moment (or crash). As you note, that's not an "every evening" option, so -

Maybe consider Brazilian Jiu Jitsu?

  - Every session is a holiday from whatever bullshit you've got going on.
  - It's a great antidote to sitting in a chair all day.
  - There's a strong problem-solving aspect to it, which can be attractive to hackers.
  - You'll immediately be physical with strangers which is a great ice breaker/trust builder.
  - Great for self-defence (and confidence), but there's no striking. (Important if you're pretty like me).
  - It may seem like an individual pursuit, but there is a strong team culture in good academies.
  - Macho douchebros don't last long in BJJ. It punishes ego. The culture is supportive/encouraging.
  - Most academies welcome drop-ins; it's a great way when travelling to meet some locals.
  - It's a great way to get to make friends of different age, sex, ethnicity, income, status, etc.
  - Competing is encouraged, but optional.
  - It's inexpensive, IMHO.
  - You're never too old or too out of shape to get started.
  - Most academies will let you try them out for free for a week or two.
  - Although it's a group activity, busy academies will have a class or two each evening.
Downsides:

  - Nobody will bother remembering your name until you've been around for a couple months.
  - You'll often be carrying some stubbed-toe level injury around (but you won't mind because...).
  - BJJ is addictive AF.
