• Learn Rust on a hardcore pro level. I am already quite good there but with Rust you have much more levels between “newbie” and “pro” compared to every other language I ever worked with. The learning curve to being really good is steep. I don’t mind. It’s a very enjoyable, if taxing, journey.
• Learn or maybe even author more Elixir tooling. As mentioned in other threads, I am mostly interested in having tools that change an Elixir project with minimal human interference. Especially in Phoenix and/or Absinthe projects I feel there’s a plethora of activities that can be automated. Additional point: maybe automatically generate controller and/or property tests based on what such a tool can “understand” about the current project’s code?
• Follow OCaml’s multicore saga. When it reaches maturity, make it my Python-like and bash-like language of choice. It always seemed like it’s very well-suited for such tasks. BTW, OCaml 5.0 is scheduled for the end of 2021 or start of 2022 and it will have multicore support out of the box, so it’s very likely I’ll just wait for that. Mentioning @OvermindDL1 here in case he has insights on the matter.
• Learn a LISP Scheme dialect – in this case Gerbil, mostly because it also has an actor library akin to Erlang (although I am not sure if its runtime guarantees are the same as Erlang’s OTP).
• Maybe gather some money to buy a very serious Linux workstation using the Threadripper 3970X – or ideally, the Threadripper Pro 3975WX, but that’s only sold in OEM worksations; still want it though! – because working on a Mac has some limitations. Mostly Docker and k8s but, using Hashicorp’s Nomad and various emerging tools that step on macOS’ newly introduced Virtualization.framework could compensate. But that’s highly optional; I haven’t met a workflow that would mandate such a monstrous power so I’d be content with abusing my iMac Pro for years to come still. But, I’d like to settle down and stop buying tech for 5+ years and I feel that investing in what’s best-in-class at the time of the purchase is a very strong guarantee that my plan will work and I won’t get tempted by new shinies for a while (hopefully!).
• Learn 1 or 2 non-programming crafts. Long-term goal, might last me until my grave even, but I feel that branching out of programming also makes you a better programmer.
• Claim back my health! This probably should have been on top.

We are, yes! A new-ish Rails app running Rails 6.0.0 (soon to be upgraded) with Ruby 2.7.2. The app is split into an front end app (build with React) and an API utilizing ActiveModel serializers to do all the heavy work.

Be able to start side projects is my plan this year.
