#AdventOfCode2022

2022 Day 20: Grove Positioning System
2022 Day 21: Monkey Math
2022 Day 22: Monkey Map

I did get stuck on day 19 of last year's AoC and never finished the remaining days.

While I am waiting for day 4 of this year, I had a go at days 20 - 22 of last year.

20 and 21 were not that hard.
But part 2 of day 22 was a bit tricky. Took me some time to figure out all the tile jumps and direction changes when crossing the cube edges.

The code is not very pretty. And the edge traversal stuff only works for a flattened cube pattern which is the same as my input 🤮​.

Code is here:

@ibboard I'm thinking of going with Python, as I did for the half a dozen exercises from #AdventOfCode2022
It's sort of my comfort language, it seems :blobfoxfloofcofe:

#30DayMapChallenge Day 28: Is this a chart or a map? Hypothetical trees in a grid, colored by height. Data from the #AdventOfCode2022 Day 8 challenge. Excited for #adventofcode2023 which starts December 1! Made with Python and GeoPandas.

I wrote this blog post about my #AdventOfCode2022 foray into #FunctionalProgramming using the #Elm 🌳 language and then completely forgot to share it! It was an interesting experience, with the main conclusion that I won't continue using Elm but that I want to keep investigating functional programming patterns and design.

Thoughts welcome 😁

Thought about solving old Advent of Code puzzles, but don't have the motivation? Me too! Here's an idea: let's do one puzzle a week.

Solving #AdventOfCode2022 day 15 in #golang with An Algorithm I Found on the Internet™ runs in 1700ms. Simplified based on the specific case (biggish change) -> 900ms. Split work into goroutines (easy) -> 300ms. Moved array allocation out of loop (easiest) -> 170ms. That'll do!

I decided to visualize the rope simulation from Advent of Code, day 9 on CodePen: https://codepen.io/DonKarlssonSan/full/wvxXVjp

It's movement is a bit weird in a fun way and the elasticity is very cool. Try it! (mouse or touch)

During #adventofcode2022, I became aware of Stable Diffusion [https://lnkd.in/eMZ-JzDD], despite not being at all interested in #generativeai #ai. After tinkering, the following are 2 images it generated in response to a concept I gave it from a particular song.
If you can tell me which song is behind the seed I gave Stable Diffusion, you win ... err... something.

My solution for day 21... Did part 2 by solving one of the Root-monkeys values and then solving the reversed of the leftover-operations with it. Runs in <50ms.

@RonJeffries Did you take a look at #AdventOfCode2022 in #Kotlin ? I’m on day 13 and I am loving a) how natural I am finding it to “think in Kotlin” for the puzzles, and b) how I am discovering language and library features as I go along by trying to solve the puzzles and then simplify them into idiomatic Kotlin. Would love to compare notes.

My solution for day 19...

Solved by checking all possible states the mining-process can be in during a given number of minutes and find the maximum number of geodes in all 'endstates' + optimizations to reduce number of states. #AdventOfCode2022 #AoC22 #Kotlin

After having spent #AdventOfCode2022 solving problems in C, I definitely feel like I have a much better understanding of the language. It was definitely interesting coding while trying to avoid unsafe functions so as not to pick up bad habits. I still can't believe I implemented a hash table for the first time without too much trouble. Still need to finish the last 9 remaining, but definitely have noticed an improvement since day 1!

My To-Do list has grown so much in December, but I haven't actually managed to do anything.

Rough To-Do list for January and February (in no particular order):
1. Spiderfire Rewrite Merge + Lots of Documentation
2. Upgrade to Iced 0.5 for die-yield-calculator
3. Finish Day 21 to 25 of #AdventOfCode2022
4. Try SvelteKit out for https://silicon.redfire.dev/ (Currently using Gatsby)
5. Improve the UI and UX of a (private) GUI software
6. Learn some HDL, either Verilog or (higher-level) Chisel

My solution for day 18...
Solved by refactoring Dijkstra-algorithm from day 12 to count where all empty spots in a path in an enclosing cube, starting outside the droplet, have sides touching the droplet. Part 2 in 1,5 sec. #AdventOfCode2022 #Kotlin

Lol #AdventOfCode2022 day 7 has been kicking my butt. Figured out how to do tree recursion in a #Scheme though (apparently you still need to use a loop in your recursive function)

My solution for day 17...
Solved by using a tower of lists of booleans. Solved part 2 by looking for a pattern and using that to calculate the total height after 1 trillions rocks. Part 2 in < 100ms
