AdventOfCode2019 VS aoc

The field is called "compiler design". Consider taking a course [1] or buying a book?

A somewhat more playful approach might be to complete the 2019 edition of Advent of Code [2], where you'll learn some preliminaries while implementing the Intcode interpreter.

The ending of Advent of Code 2019 was amazing. Well, the whole season was awesome, but the ending was amazing.

2019 in Rust

This is the seventh year puzzles, if you want to check out previous years take a look at: 2015, 2016, 2017, 2018, 2019, 2020

I believe this is the direct link to the mentioned challenges: https://adventofcode.com/2019

If you want to get started, I would recommend doing Advent of Code 2019 https://adventofcode.com/2019. It goes through and shows how to implement a basic VM. 0x10c / DCPU-16 is also a good place to start. Such simplified CPU-s help you get started and understand the basics without overwhelming you with the complexity :D.

Overall, I think this year felt a lot easier than the last one. Almost no graph problems, no path finding algorithms, and no insane math problems like day 22, 2019. It's really hard finding the right balance. I think 2019 was maybe a bit too hard and discouraged a lot of people. I like that this year was more approachable but perhaps it was a bit too easy towards the end.

Thanks for an amazing year! Definitely a lot easier this year than last one, which was a bit sad. No hard graph problems, requiring path finding algorithms, no insane math problems like day 22 last year. It's hard finding the right balance. I think 2019 was maybe a bit too hard and this year maybe too easy.

Code, such as it is, is checked in here.

Merry Christmas! As a simple Christmas Card, here's an input file for day 9's decoder that produces this scene.

Watching the Elves dance around till they all find a little space they can be happy in. Code's here on github

Probably not the most useful visualization, but I wanted to see what was going on. Lines represent the nodes being moved along the circular buffer, and the color of each node is the final position along the node. Code's here on github.

Took a stab at making a little compiler for Day 10 so I could draw my own messages. This is the result, though in theory it can draw out any 8 character message, within some limits. Code's here on github

Like most days the solution for this day is mostly stand alone Python code. For days that involve a visualization, there are two important caveats:

Watching a madman drag a rope around. Code is on github

Just some fun looking at a visualization of the size of the file system presented in the puzzle input, using a tool meant to help you visualize AWS S3 buckets. The code to dump out the input is a small addition to my puzzle solver.
