#adventofcode2023

@monkey1 yeah, I found out about #guile and got curios about #scheme when I researched #guix .
I appreciate #clojure more after the small amount of time I spent on scheme. Especially tooling. #Calva is awesome for Clojure! So far I failed to replicate even a small part with #Emacs (which I am also learning as I go)

Doing #AdventOfCode2023 in scheme and learning as I go. Did not reach continuations yet. Heard a lot about them.

@abcdw I'm doing #adventofcode2023 in #guile and I miss (comment ) blocks and rich-comment-test github.com/matthewdowney/rich-

That would be great to have in #guile #scheme . I don't know how people develop without them :)

A few weeks ago I decided to start doing the #AdventOfCode2023 exercises in #CommonLisp. Despite barely knowing anything about Lisp I managed the first star without too much trouble beyond having to look a lot of things up. Then for the second star I almost immediately figured out how to do it but spent several days finding out how to express that solution in Lisp without making it too confusing.

I'm super stuck with part 2 of Day 10 of #AdventOfCode2023 but at least I created this cool visualisation of the pipes loop/labyrinth I got in Part 1

I've almost completed all of Advent of Code 2015 (only 9 years too late!). Day 21 was super fun, but Day 22 is possibly going to be oof.

Crazy how much difference the right data structure / #algorithm for a task makes.

This week I learned about #Deterministic #Finite #Automata and #Nondeterministic Finite Automata just to redo my clunky #AdventOfCode2023 day 12 challenge, written in #Rust #RustLang

Runtime for part 1 dropped from 1-2secs to milliseconds. Part 2 also milliseconds 😮

Are there any good Rust crates for DFAs/NFAs?

Many people solved that problem with #Dynamic #Programming - something else for the learn list 😉

On the Criteo Engineering blog, I shared, along others, my experience of participating in Advent of Code 2023.

finally I completed advent of code better late than never 🙂 #AdventOfCode2023 #AdventOfCode

You supply all fifty stars and restart global snow production!

As you reach the edge of Snow Island, you can already tell from way up here that everyone will have a white Christmas this year after all.

Congratulations! You've finished every puzzle in Advent of Code 2023! I hope you had as much fun solving them as I had making them for you. I'd love to hear about your adventure; you can get in touch with me via contact info on my website or through Twitter or Mastodon.

Advent of Code 2023 recap blog post dan-schreiber.com/blog/2024/1/. Thanks to Eric Wastl and @adventofcode for another great year.

Trying to do #AdventOfCode2023 Day 25 to be close to wrapping it up.

Apparently the "Stoer–Wagner algorithm" finds the minimum cut to split a graph.

Except the Wikipedia example code is apparently broken, and all of the other examples I've found are REALLY shit with their naming.

It's easier to teach a mathematician to code than it is to teach a programmer maths. But that doesn't mean the mathematician can be trusted to write readable code with sensible variables 😐

On to Day 24 of #AdventOfCode2023 and… UGH! Is there any way to make this not horribly maths-y? I've yet to find anyone online giving a clear approach (and I took maths through to A Level… 20 years ago!)

None of this is made easier by Google being "helpful" and putting lots of "intersection of sets/arrays" content at the top when searching for intersection of vectors in a given programming language 🧐

Hey, look! It's another #AdventOfCode2023 where the sample is correct, everything seems to make sense, and yet my answer is too high. But the full input is so complex and there's no ground truth and so I have no way of finding out which corner case I'm apparently not handling 😐

2024-01-03

I think I've worked out where my limit is with #AdventOfCode2023.

Got to optimise an implementation and use the right data structures? Fine.

Got to plot things out to find patterns and mathematical shortcuts (especially if it's a shortcut that you've got to know rather than find)? Screw that and leave the boredom for the mathematicians!

Advent of Code 2023, Day 25

Time to wrap up last year's #AdventOfCode. It was a lot of fun, I learned a lot of new thing and finished with 36/50 stars.

I solved puzzles with #Python, writing explanations and educational tidbits along the way while discussing them and reading solutions from a wide variety of people using different programming languages.

This retrospective includes a couple of spoilers but is mostly conversational and not about the solutions directly.

Advent of Code 2023, Day 24

Yes, I'm a bit late. Holiday travels put a pause on my #adventofcode activities for the year, but here's my AI image for Day 24.

#adventofcode2023

Day 19 of #AdventOfCode2023 wasn't too bad. I even found a generalised way to turn "<" and ">" into operations and call them in Ruby!

But I'm just glazing over on Day 20. As much as I hate being defeated by coding challenges, and as much as I enjoyed doing Seven Languages in Seven Weeks, I think I need to call it quits with this.

It has gone from "interesting distraction and challenge" to "you're being so obscure that I just can't bring myself to care".

2024-01-02

Trying to catch up on #AdventOfCode2023. Working on Day 18. Almost had it, but the inside count was missing some conditions. Restructured it so it worked with Day 10s "inside the loop" area finding algorithm. Success!

Then got to part 2. Parsing is trivial. The sample took impossibly long, so the full input is right out.

Read up online. Shoelaces and Pick's theorem? WTF? I'm a programmer, not a bloody mathematician 😐

There's "interesting challenge" and there's "teaches you nothing useful".

After regularly switching between , , , , and to solve puzzles, my head is mush about syntax. Could it have been more worse if I had used more languages, e.g., , , ? 🤷‍♂️
