A strange package has arrived. Received for my outstanding performance on last year's #AdventOfCode. Except the year is wrong on the shirt :) I suppose it's a prediction for this year's event ;-p

#Kotlin #Kodee #AoC25 #AoC26

@blinry and I are still trying to solve last year's #adventOfCode. We're stuck on day 10, and we're out of ideas – except using linear optimization algorithms, but that feels like overkill... Has anyone of you solved day 10 and has a tip for us – do we really need to implement linear optimization?

Please use a spoiler for your answers ^^'

Aaaaah, the horrors, what a nice evening! @blinry and I finished day 2 of the advent of code in sqlite.

As you probably guessed, the screenshot only shows the lower third of the program, there's more "with recursive" where that came from :>

This is not good code, don't try this at home. We wanted the pain.

Advent of Code Day 5: Iterates over RAM holding fresh ID ranges. Autopipeline checks N IDs against M ranges each cycle. Easily does N=3,M=2 at ~235MHz, ~1.4 billion ID-in-range checks computed per sec 😎

Advent of Code Day 7: very simple design, good intro to #pipelinec. processing all ~hundreds of elements of an entire line each cycle. ~600 million to ~5.3 billion tachyon beams splitting per second. 😎

Advent of Code Day 4: video-like stream of 'pixel' data to a sliding 3x3 window via line buffer fifos. Auto pipeline for kernel function (counting neighbors), ~150M windows per sec. https://github.com/JulianKemmerer/PipelineC/blob/master/examples/aof25/day4.c

Advent of Code Day 9: Iterates over RAM holding points. Autopipeline computes N rectangle areas per clock cycle and finds max. Easily does N=4 at ~100MHz with few pipeline stages, ~400M rect areas computed per sec 🎄
