My favorite part of the marathon is the view from Eden Park. Helps that you only get here by conquering a mile of hills

Advent of Code 2025 done! 🥳 I'm actually glad this year was shorter, made it way less stressful. Got trolled a bit on the final problem, but this was a lot of fun :)

Advent of Code 2025 Days 10/11 blog posts now up! Day 10 Part 2 sucked, I hate that the standard solution for those problems is "just use z3". But glad I could do something fun at least Day 11 was the first time I nailed using a recursive CTE with zero assistance, very happy about that! 😁

Advent of Code Day 11 Part 1 solution, using a recursive CTE to calculate paths between nodes.

Advent of Code 2025 Day 11 done! Part 2 just required memoization 🤦‍♂️ took way longer than it should have, but at least Part 1 was easy!! Still drained from Day 10, gonna chill for tonight and do a write-up tomorrow

LETS FUCKING GOOOOOOOOOO

Advent of Code 2025 personal times, with Day 10 at the top. My Part 1 time for Day 10 is 1 hour, 16 minutes, 13 seconds. My Part 2 time for Day 10 is 23 hours, 54 minutes, 24 seconds.

Not thrilled about it but did find a workaround 😝

First night I'm not solving both parts in one go 😭 Part 1 was a bit challenging but my brute-force solution worked. I seemingly can't get a fast enough BFS solution for Part 2, so matter what I do

Fletcher @fletcheaston.com · 09/12/2025

Advent of Code 2025 Day 9 done! I knew exactly what Part 2 would be as soon as I saw Part 1. I didn't bother coming up with a general solution, just wrote a quick and dirty query with some shortcuts Plotted the points in Desmos to help find those shortcuts 😎

Advent of Code 2025 Day 8 done! It took me way too long to figure out what the prompt was even asking me for Part 1 😭 And of course there was an edge case that I hadn't accounted for Part 2 was relatively easy though!!

SQL query calculating the final result for my Advent of Code 2025 Day 8 Part 2 solution. The query selects the last member from the "circuit members" table, finds the closest node to it, and returns the x-coordinates of the two nodes multiplied together.

Sucked but eventually got it. Bedtime, posting about it tomorrow ¯\_(ツ)_/¯

Advent of Code 2025 Day 6 done! Calculating the result was easy, it's just the complex string manipulation that's really really hard

Advent of Code 2025 Day 5 done! The Postgres range types are so good, 10/10 made my life very easy tonight. Also enjoyed using the CTE trick to read, delete, and write data to a table in a single statement Also forgot to post about Day 4, but finished that last night after a bit of tinkering 😰

Fletcher @fletcheaston.com · 03/12/2025

Advent of Code 2025 Day 3 done! My Part 1 Solution is extremely fugly, but made good use of a helper function in Part 2 for a more verbose but much cleaner solution

Screenshot of a helper function in Postgres. The function is called "largest_index", and it calculates the index of the largest value in an array given exclusive start/end positions.

"give us 15-20 minutes" and then it's still not ready 40+ minutes later. Like it's cool if y'all are busy, just give me a realistic time to come pick it up 😭

My local Main Hot Chicken store has updated take-out packaging and it's SO MUCH BETTER than the old packaging. There's a functional lid, the fries come in a bag, and the box no longer leaks. Amazing

14 miles at ~10 min/mile. Not particularly fast, but I felt really good the whole run! Carrying water sorta sucks until you're a mile away from any pubic water fountain and you've still got a liter of cool water on your back

40 miles a week for the next month, trying to build a bit of speed instead of pure volume. Then back to 10% week over week increases for awhile
