I just completed all 12 days of Advent of Code 2025! #AdventOfCode adventofcode.com Don't spend much time thinking about day 12; try the simplest option first. I did this as a gut check to trim out unnecessary trials; on a chance, I submitted the answer - it was correct. github.com/ymiseddy/Adv...

I've completed "Reactor" - Day 11 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/11 First directed graph. I was overthinking it and got some outrageous answers for Part 2. github.com/ymiseddy/Adv...

I just completed "Factory" - Day 10 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/10 Part 1 - tried Dijkstra's, but was too lazy to implement a cost function, so it degraded to BFS. Part 2 - was crazy - tried A*, linalg solver, ended up with linprog FTW. github.com/ymiseddy/Adv...

I've completed "Movie Theater" - Day 9 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/9 It took a bit to find a reasonably efficient algorithm for part 2. I'm still not convinced it is the best. github.com/ymiseddy/Adv...

I've completed "Playground" - Day 8 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/8 This is my favorite so far! Messy code - I may do some cleanup later. Solution is here: github.com/ymiseddy/Adv...

I just completed "Laboratories" - Day 7 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/7 Solution is here: github.com/ymiseddy/Adv... Part 2 - first attempt grew exponentially, so I had to find a better way.

I just completed "Trash Compactor" - Day 6 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/6 I spent too much time trying for a pure-math solution to part 2 before realizing that the padding made that impossible. github.com/ymiseddy/Adv...

I've completed "Cafeteria" - Day 5 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/5 Be careful with those overlaps! Here's my solution: github.com/ymiseddy/Adv...

I just completed "Printing Department" - Day 4 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/4 The Part 1 solution is easy to reuse for Part 2 - I was even building a new map so I could display it for debugging. Solution code is here: github.com/ymiseddy/Adv...

I just completed "Lobby" - Day 3 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/3 I went with the direct solution for both parts. github.com/ymiseddy/Adv...

I just completed "Gift Shop" - Day 2 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/2 I just went with the messy, obvious solution for both - I'm certain there were some optimizations to be had: github.com/ymiseddy/Adv...

I just completed "Secret Entrance" - Day 1 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/1 This year, I'm doing solutions in Python. Here is a link to today's solution on GitHub: github.com/ymiseddy/Adv...

If you go many years with a hammer as your only tool, you get really good at pounding things.

I'm impressed with the responses I get from my local Deepseek instance. It is reasonably performant and gives excellent responses. I also like reading through the thinking sections to see how it reasons about its response.

I just completed all 25 days of Advent of Code 2024! #AdventOfCode adventofcode.com I have to say, the past 25 days were adventurous! Long time SWE, first time doing AoC. I am currently going through the Easter Eggs in the earlier problems. github.com/ymiseddy/Adv...

I just completed "Crossed Wires" - Day 24 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/24 This one was a complete pain; I haven't worked with binary adders in decades. I resorted to flat rule checking on this, and surprisingly, it worked. github.com/ymiseddy/Adv...

I just completed "LAN Party" - Day 23 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/23 Part two took abnormally long because I got burned by one of Go's footguns in how it handles slices. github.com/ymiseddy/Adv...

I just completed "Monkey Market" - Day 22 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/22 Ok, I stayed up for this one. The hardest part was parsing what the heck these monkeys were doing. 🐒🍌🍌🍌🍌🐒

I just completed "Keypad Conundrum" - Day 21 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/21 I've decided not to stay up late to try to solve these. I'm glad I didn't for this one; it took me quite some time.

I just completed "Race Condition" - Day 20 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/20 I tried a few dumb ways before stumbling on a reasonable way to find cheats. BFS is overkill for finding the initial path since it doesn't branch. github.com/ymiseddy/Adv...

I just completed "Linen Layout" - Day 19 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/19 I would have finished this one faster if I hadn't written bugs early on. github.com/ymiseddy/Adv...

I just completed "RAM Run" - Day 18 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/18 Today, I made it hard for myself, thinking I had to compute the path while the rocks were falling on part 1. After I figured out that mistake, it was straightforward. github.com/ymiseddy/Adv...

I just completed "Chronospatial Computer" - Day 17 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/17 Both parts were interesting - implementing a small assembly language and figuring out how to generate a specific output. I'm surprised my solution worked! github.com/ymiseddy/Adv...

I just completed "Reindeer Maze" - Day 16 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/16 Finding Go's heap structure and building a priority queue to implement part 1 took me forever.

I just completed "Warehouse Woes" - Day 15 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/15 I got both of these on the first try tonight. Both parts were straightforward, with no particular tricks involved.

I just completed "Restroom Redoubt" - Day 14 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/14 Part 1 was not too hard; Part 2 took a bit of ingenuity since you don't know what the image is supposed to look like. See comment on line 140. github.com/ymiseddy/Adv...

I just completed "Claw Contraption" - Day 13 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/13 I dipped into Python for this one because I don't know the Go version of numerics well enough to solve this. I may go back later on today (after some sleep) to figure this one out in Go.

I just completed "Garden Groups" - Day 12 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/12 I started today's problem late and floundered quite a bit on part 2. github.com/ymiseddy/Adv...

I've completed "Plutonian Pebbles" - Day 11 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/11 It was a real head-scratcher trying to figure out a "fast" path for part 2 🤔. It took a single realization, though. If you give up, see my comment on line 24 🤷‍♀️. github.com/ymiseddy/Adv...

I just completed "Hoof It" - Day 10 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/10 Another dynamic programming solution. I accidentally got the answer to part 2 first because I was counting distinct paths. 😀 github.com/ymiseddy/Adv...
