Day 29: • More bugfixing on Milkyway Pets. I need to be testing builds via WINE or my vm because otherwise stuff keeps breaking in production which is not a good look. Worked on Burning Rain in a huddle. • Got one :aoc: from day 6. It's not much but it was fun • Made some drawings for my website! • I downloaded the demo for UNBREAKABLE after Hex4 linked it and wow. I only played for like half an hour, but it felt like style was being injected directly into my veins. That's the level of cool I aspire to have in my games one day. Thinking a lot about the interactions between setting/aesthetics and story. • Also found the phone that I've been missing for most of the year. Turns out my mum put it in the back of a drawer and forgot about it :skulk: There's a few 2FA things it'll be nice to get back, but I don't really have a use for it now (especially as it's missing a power button)

:50days: Day 28/50 Today's AoC may be the slowest I've ever done... with part 1 only takes 8ms takes up to 20s :skulk: (depending on if I use pypy or python) I installed pypy on my laptop but it's kinda weird cuz sometimes it's faster (part 1) sometimes it's not (part 2) probably because i'm using a library for polygons of part 2 and not on part 1 :shrug3d: I've also started to read an scientific article

day 28 of 50 days to 2026!!! I got to do a long study sesh with a few friends focusing on Calc and C++ which was fun. One of my friends ended up writing out a hilarious short story prompt for a program that we wrote to test all of our concepts. I also released bore today with a youtube video for it! It is a super fancy reverse proxy tunnel manager like ngrok but running entirely on my own infra! It is based around the open source frp software which is great on its own but a bit annoying to use in the oneshot command type way I was used to with ngrok. I wrapped the client cli in a nice gum interface and used nix to package it with a super fancy man page and shell completions! Bore also has a really cool dashboard at bore.dunkirk.sh which shows active tunnels and how much data has been transferred along them as well as a few other stats. It also has a really fancy 404 page which I'm quite proud of. Also working on my shell config I setup zmx which is a light weight tmux alternative that just keeps persistant sessions. It works quite well for my needs and I also set up ssh pooling so connections are next to instant now! I also did a bit of work on crush adding support for refreshing api keys whenever encountering 401 errors. I also whipped up a quick nix flake for it as well and got that working! www.youtube.com/watch?v=4ztWxaYOL7E

Cupboard door knobs are the singular, defining elements that provide both functional access and crucial aesthetic detail to cabinetry throughout the home—from kitchens and linen closets to built-in storage. While often used interchangeably with "cabinet knobs," focusing on cupboard door knobs emphasizes their role in various rooms beyond the main kitchen, including utility rooms and wardrobes, where durability and style continuity are paramount. http://infinitydecor.co.uk/collections/cupboard-knobs

days 26 and 27 of 50 days to 2026 Yesterday was a long day of work so I was sadly not able to get much done beyond AoC but I did get a nice visualization done for day 6 as well as a visualization contributed by one of my friends jasper which looks amazing! Over the last couple of days I've been refining a script to take incoming college emails which are mostly spam and filter out just the important ones. So far its working fairly well and I'm happy with how reliable its been. If you want to run your own then the code is over at tangled.org/dunkirk.sh/filter-college-spam
