Parser combinators in #Haskell are like the cool kids at school , effortlessly solving Advent of Code problems while #regexes are stuck in detention . Who knew regexes were still a thing in 2025? In Haskell, we leave those relics to flounder in the past while we flex our combinator muscles .

I just completed day 1 of #AoC 2024, I know, I'm late to the party but I am learning #clojure so thought I would learn better if I did something with it.

I will be uploading my solutions to github as I go forward, And I will probably be using multiple languages to solve the puzzles, to get better practice with different langs and also compare them.

I just completed "Mull It Over" - Day 3 - Advent of Code 2024 #AdventOfCode https://adventofcode.com/2024/day/3

At last night’s @mug meeting we looked at a lot of different solutions to #adventofcode day 1 in many different languages. Two that were very interesting to me were #Zig and #haskell. The way these two languages worked was really quite fascinating. After seeing real code in these two languages, I can tell they are not for me; but they were interesting and illuminating nonetheless.

There was a solution entirely in #SQL. Another in #vim9script. Another in #swiftlang #swift (I don’t think that one’s in the repo yet). I wrote several implementations myself. The one I felt most proud of is #Python with the core written in #rustlang #rust tied together with #PyO3. The one I felt was maybe the best tool for the job was entirely based on #pandas. As I said in a previous post, I tried to solve it in #polars, but the API exposed by Polars at least as far as I could tell, made it no better than simple lists in Python. I need to get deeper knowledge here.

The repo lives here: https://github.com/MichiganUnixUserGroup/MUG-2025-03-11-Advent-of-Code.

I solved a small problem trying to do it using only #pandas (it was #adventofcode day 1). I know Pandas pretty well. The solution to both parts together turned out to be very short.

Tried to do the same thing in #polars. Way harder. Didn’t get to leverage DataFrames. Basically just used Series and they were just glorified lists. This was my first experience with Polars. So my ignorance was certainly a factor. But wow. Pandas just did the job better. I’m sure Polars is still growing. I really want to like it!

I want to go for an easy language for the next #AdventOfCode. The obvious choice being Python. And I really liked using my old PC in 2024, soooo I’m thinking about doing that again to get a proper #RetroComputing theme.

And I would also love to have a UNIX shell this time.

So, how about going for SuSE Linux 6.4 and Python 1.5?

(Yes, I’m planning ahead. )

I put off writing this for two months, and I am not happy with how it came out but I am trying to blog more regularly so here's an article on how to write a defmemo macro in #elixir which I did during the 2024 #adventofcode

I just completed all 25 days of Advent of Code 2024! #AdventOfCode #python https://adventofcode.com/

I returned to Day 21 Part 2 last week, finally got the 'shape' of the problem but failed to solve it again. Yesterday I restarted from my Part 1 solution and after some toe-stubbing it finally works! (silly mistakes are more obvious the next day)

AOC has been great for levelling up my Python skills and reminding me this is fun...sometimes.

Thank you @ericwastl !

New instance, new introduction!
I'm a late (mostly self) diagnosed autistic in recovery from autistic burnout. In spring 2024 I left a career at Apple Retail and have been finding myself since. I'm deeply passionate about and experienced with Apple tech. I also love Sci-Fi and Fantasy, mostly TV and movies these days. I'm a gamer, mostly playing on Mac, iPad, and Switch. I was once a software engineer and still pursue it as a hobby, mostly developing small projects for the Apple ecosystem in Swift.

@ericwastl I just completed #AdventOfCode 2019 and my goodness, what a masterpiece!

I really loved the Intcode interpreter and day 25 was a wonderful star at the top of the tree. Thank you so much!

I just completed "Garden Groups" - Day 12 - Advent of Code 2024 #AdventOfCode https://adventofcode.com/2024/day/12

Casually working through #AdventOfCode 2019 and reached a problem that has a natural solution involving affine transformations in modular arithmetic so in 40 lines of code (including pretty printing) I implemented a fairly complete system in #JuliaLang.

Truly a joy to work with
