AGI finally achieved: Gemini uses the "works on my machine" argument

Finishing the year strong with a new project with which I MIGHT have finally figured out running modded games on Proton

(copium)

I've completed "Movie Theater" - Day 9 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/9

Not particularly fancy, but I'd have given myself nightmares if I tried doing p2 with simd.

I just completed "Playground" - Day 8 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/8

No SIMD for this one, and it's slow as heck :') But at least it's concise.

I've completed "Laboratories" - Day 7 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/7

Lol, my almost branchless SIMD solution's speed is statistically indistinguishable from the naive loop

I just completed "Trash Compactor" - Day 6 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/6

Part 1 was fun with SIMD but with the parsing and allocations it took 3x as long as part 2, which was a very brutal u8 twiddling. Oneshot both anyway!

I just completed "Cafeteria" - Day 5 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/5

I'm not sure if it's because SIMD is my current hammer, but this one looked an awful lot like a nail

I just completed "Printing Department" - Day 4 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/4

So satisfied with my `portable-simd` based solution today. I have no idea if it's even faster, but I don't care, it was so much fun!

github.com/veeenu/adven...

I've completed "Lobby" - Day 3 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/3

I ran out of time and patience to do the SIMD thing in C so I just did what you can readily imagine.

Surely it's 100% skill issue and I'm missing something incredibly obvious that leads gcc to think that (32 == 32) is false

I've completed "Secret Entrance" - Day 1 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/1

I'm SO going to regret this
github.com/veeenu/adven...

I had a thing in my shell init that read the mode and set an env variable, which I'd then use to set the theme in the neovim config. Had to reopen the terminal for switching though, which was annoying, and never bothered finding a better solution.

Please enjoy this inverse kinematics simulation I made with Bevy!

I'm building a robot arm as a toy project and was looking for a way of controlling it via translating x/y/z rather than changing angles directly.

This seems promising. Maybe with some CV I could make it e.g. grab stuff autonomously.

Every time I try a new thing and it works out ok it feels like I cracked another secret of the universe even if it's the silliest thing

Unless you want all sorts of different vehicles you could just make that into an enum. Of course then your kick scooter is going to take as much space as a Harley-Davidson but at least you don't have to allocate on the heap.

I'm this 🤏 close to raising a series A for my up-and-coming hardware AI blockchain web 4.2.15-alpha1 startup

I discovered Niri yesterday and I can't understand why this is not the de facto mandatory standard of interacting with computers already. This is SO GOOD

I did all my teenage years with open source msn clients that lacked most features and in doing so locked myself out of the vibe of the generation, so it was a knife that cut both ways

I also have all those disks myself, and no single piece of hardware capable of reading them 🥲

It is with deep regret that I must announce: I am old as HECK

I was moving boxes of magazines/books I had when I was a kid into the attic and accidentally found my villain origin story

Tail call optimization just landed in rust nightly! github.com/rust-lang/ru...

This completely blindsided me. I remember discovering Rust didn't have tco in like 2018 and never thought anyone was working on it. Amazing

I feel that. When I started out it crashed all the time and the user experience didn't make a whole lot of sense. But at this point I've grinded enough that I rarely ever run into issues anymore 😅 and am grateful for all the community effort that has gone into it.

I landed on FreeCAD after finding everything else grossly inadequate. FreeCAD has made leaps and bounds recently; it is still kinda hard to get into, but I recommend watching MangoJelly's tutorials as they make it a relative breeze.

gives me fond memories of that time I spent a week trying to troubleshoot a Python data pipeline taking literal minutes to start, and in the end it was the company antivirus checking numpy's DLLs over and over

My second-try Heolstor solo. I played it like a donkey but hey, at least I got a flashy start of phase2.

I didn't really like the art style, but the story is great.

I engineed the enginee that was engineered today

it doesn't work, I haven't written the firmware yet and the front wheels are all wobbly as heck but ehhh it's still a zero-to-irl-thing in a handful of hours
