Advent of Code in Unison, Day 7

share.unison-lang.org/@nathanielkn...

This was _much_ smoother than day 6 for me. The solid block of characters made for an easy parser and the data structure I used for part 1 transitioned nicely into part 2.

Advent of Code in Unison, Day 6

I made bad choices (or got unlucky) with my parser for this one and had to re-work it substantially for part 2, which is a shame because the parsing is the hard part on this one.

Advent of Code in Unison, Day 4!

share.unison-lang.org/@nathanielkn...

Grid based puzzles are always a good time. My favourite trick for these is to use an associative data structure for the board instead of a nested array.

Day03 of Advent of Code: the return of Joltage!

A few hurdles dealing with List functions, but otherwise a pretty straightforward puzzle.

🎄 Day 02 #adventofcode

I tried to stick to solve without resorting to text conversion and purely with arithmetic means. I am sure there are more optimisations possible, but it's been fun. #adventofcode #aoc #unisonlang

Since BYOC solves the data residency concerns that come up with EU companies, I am planning to experiment with it next week.

Coming from AWS Serverless (Rust/TypeScript) and Elixir/OTP, I'm curious how Unison's approach to distributed computing feels in practice.

More to come :)

Finally had time to get my index.html into #unisonlang and serve it locally. I haven't been super motivated to work on this project but making some progress!

This is a really neat library share.unison-lang.org/@systemfw/vo... #unisonlang. Pretty tempted to use this for my Erlang -> Unison re-write project. It would be a great opportunity to learn more about event streams.

#unisonlang this has a good tip www.unison.cloud/learn/microb... related to the Storage versus Cloud ability. I hadn't realized I couldn't just create my database deep within my app. I _do_ need to pass this down into my application code.

#unisonlang tip: if you are doing HTTP client requests on Unison cloud make sure to use the `Http` ability and don't use the `IO` ability (i.e. you don't use `Http.run do ...` to interpret your effect). The `Cloud.main` function will interpret your `Http` abilities.

#unisonlang tip: `lib.install` will get you the latest version of a library. You can then upgrade with `upgrade {old} {new}`. Use `ls lib` to see the names (ucm has autocomplete and fzf too). If you don’t need a lib, use `delete.namespace lib.{unused}`.
