don’t want to look at today’s 🧵 and have it spoiled, so i’m just gonna ask those who have finished it something in this 🧵 :

What a pain

I'm currently using IntelliJ Idea - Edu version for doing the AOC. Most of my work mates are using Android studio by default and it would be a barrier for them to join AOC, by installing other IDE. I made a small project in Android Studio, with unit test configured to read input txt from resource folder. Hope it is helpful. (Any suggestions to make it better are welcome) https://github.com/monsterbrain/advent-of-code-android-studio-template

🔥 Get ready for a very special Day 8 of Advent of Code! Kotlin Project Lead and competitive programming champion @elizarov will be joining us for today’s livestream. Let’s dive into Kotlin and solve the puzzle together. Don’t miss it!

I just completed day 5, and I realized that day 5 input was one of the hardest inputs that you can have to parse and read in the challenges.. especially the column things in the beginning...🥴

Part 1 (initial)

A question about example in day9: 🧵

🎄 Tune in to our today’s livestream with @ilya.gorbunov, one of the engineers working on Kotlin’s standard library, for a fun chat – and the solution to today’s puzzle, of course!

👋 Hello, team!

Is there a way to get something like this

abstract class AdventDay(input) { abstract fun test(input: Something): Int }

so that Something is either List<String> or Sequence<String> or String? And you can decide in the implementation which one you choose?

Mutable state machine for me again 🤣

Does everyone have super large monitors to take screenshots of their code windows with and I'm the only one typing away on a 15" laptop, or is there a plugin or something that generates pretty screenshots?

🎁 Get into the holiday spirit and join us for Advent of Code Day 10! Tune in now for a livestream hosted by the amazing @Sebastian Aigner, with special guest Nicole Terc!

Has anyone built any visualisations with Desktop Compose?

Can anyone who has implemented JMH or kotlinx.Benchmark answer a question for me? Documentation for kotlinx.Benchmark beyond the Readme seems to be nonexistent, and the Readme is out of date, incomplete, and assumes more knowledge of Gradle than I have. There don't seem to be any YouTube videos about it and discussion in the kotlinlang Slack is old and minimal. I tried to figure it out and finally got to the point where I could create an annotated Benchmark class without the linter screaming at me. And then... nothing. I have no idea how to actually run the benchmark! How do I do that?

That was easy thanks to kotlin's lambdas

So, I’m currently at day 5, can I just hardcord the inputs only for stacks? 😅 Parsing the input seems to be a nightmare 👻 Edit: I parsed it

❄️ Day 11 of Advent of Code is here! Join us as we discuss the puzzle of the day with @Olaf Gottschalk.

The fastest way to code part 2 with my utils, was to make it off by one (having it take a step from 'initial' to all possible first locations) but the path of part 2 was only 1 cell shorter than part 1 so they were giving the same value and I thought intellij was just bugged and running my part 1 code instead of part 2

⭐ Join us for the final livestream of Advent of Code in Kotlin! Day 12 will be hosted by the wonderful @Sebastian Aigner, with guest @Dave Leeds, who creates cartoons about Kotlin. Don’t miss out on today’s fun at 5 pm UTC!

Tonight we will cross the 50% mark!

Not mine, but I definitely relate: https://www.reddit.com/r/adventofcode/comments/zjwovn/so_youre_trying_to_get_onto_the_leaderboard_huh/

Think i’m misunderstanding a rule from today… 🧵

if i put my input for day 12 in a thread, can people take a look and tell me if i'm losing it? 🧵 to avoid spoilers

Wow do I love Kotlin!

hm - the test set work for part 2, but not my input - any obvious low-hanging hints I probably have forgot? 🧵

So I revisited Day 13 to commit some crimes against Kotlin today. I wondered what would happen if instead of parsing the input "properly" (which I did on the day, and took me far too long), I instead turned it into some Kotlin code with simple string replacements and then tried to dynamically load the result into the running process (like calling

eval

in Python). TL;DR is that it works, but it ain't pretty 😂 Details in 🧵

Here comes today’s solution 😁
