 I'd done microcontroller work on dev boards before and it always felt like I was renting the hardware. As soon as I had a real board with my own soldering on it, bugs stopped feeling like software inconveniences and started feeling like consequences of choices I'd made in KiCad. That shift was most of the value of doing it this way. Four years on from [my first hardware project](/articles/lights-synchronized-to-music/), the lesson was that owning the whole stack down to the copper changes how you debug.

 Keeping it here because pretending the older work didn't happen would be dishonest. The first browser game I wrote, January 2018. It isn't good, but it was the moment a `<canvas>` element stopped being mysterious.

 Once you self-host a few services with live databases, the backup question stops being theoretical. A Postgres or SQLite file half-written when `tar` reads it goes into the archive in a state nothing on Earth will replay; you just don't find out until the restore. Two years in, with multiple incidents I had to actually recover from (including the photos behind the [e-ink frame](/articles/frame-eink-photo-display/)), I trust this stack precisely because the correctness argument is short: BTRFS gives me an atomic snapshot, and everything above it can be a shell script. One Alpine container, ~75 lines of Bash, pushes that snapshot to one or more [Borg](https://borgbackup.readthedocs.io/) repositories on a fixed interval. Multi-target is numeric env vars (`BORG_REPO_0`, `BORG_REPO_1`, ...). No config format, no DSL; the env file is the configuration.

 Most security challenges punish wrong answers with a red "incorrect." This one punished them with car wrecks, and people learned faster. A PLC cybersecurity event in the summer of 2018 needed something visceral; I built a small Unity city where the traffic lights were driven by a REST API and contestants wrote the control logic.

 My thesis was a renderer; proving it in a real multiplayer loop was the point. A real game loop is a worse audience than a tech demo. That's the point. So through autumn 2020 I built decla.red on top of [SDF-2D](/articles/sdf-2d-ray-tracing/): a conquest-style space shooter, two teams, small planets, ray-traced 2D rendering, browser and mobile. The architecture decision worth remembering came out of needing the server and the client to stop lying to each other: one TypeScript module containing the game rules, linked by both sides of the wire.

 I needed it. In my last year of high school I was about to sit the _emelt szintű_ (advanced-level) physics érettségi, and the practice material I could find online was either paywalled or scattered across PDFs that wouldn't tell you whether your answer was right. So one evening I started typing past exam questions into a JSON file. A few weeks later I had something resembling a study tool, and a few weeks after that I had 659 questions covering more than a decade of past papers.

 Nine numbers in `{-1, 0, 1}` arranged in a 3×3 matrix decide an entire vibe's personality. That constraint is what kept me up: proving simplicity can be expressive, that you don't need a behaviour function per preset. A WebGPU drawing toy where you stroke a colour, agents spawn along it, and the garden slowly overwrites the patch you laid down. One static HTML file, six compute stages, none of them skippable.

 In the autumn of 2019 I was an undergrad with a few weekends free and the quiet conviction that I could find a small edge on EUR/USD. The screenshots were flattering: the prediction (blue) hugged the actual rate (green) in a way that looked like skill. A linear regression in the frequency domain, dressed up. I did not trade real money with it, and that restraint is the only thing about the project that aged well.

 In 2024, researchers found family-blog photos of Brazilian children inside the LAION training set. Self-hosting your photos used to be a preference; it's a safeguarding decision now. Nixplay's cloud-tied frames have bricked. Funimation deleted libraries people had paid for. I wanted a photo frame on the hallway wall, and I wasn't going to hand the family album to a vendor who could close the doors on it.

 Non-technical event organisers needed to rewire a cooling plant in real time without me hovering. That was the brief, and it ruled out every interface I'd have enjoyed writing. The [cooling system sim](/articles/nuclear-cooling-simulation/) was only as useful as the tool that fed it, so in late 2018 I built a JavaFX desktop editor: lay out the plant as a graph, edit each element's parameters in a side panel, export JSON, or upload straight to the backend.

 By the end of 2021 I had stopped believing the people skipping ML deployment best practices were the problem. They knew the list. They agreed with the list. They had a deadline, and every item on the list cost five lines of glue. My MSc thesis turned that into the actual research question: not "what should engineers do" but "what API shape makes doing the right thing cheaper than not." The framework that fell out, `great-ai`, is a decorator on a plain Python function. The thesis behind it is the part worth reading.

 In August 2019 I wanted a goal tracker I'd actually open, on whichever device was nearest, without watching it disagree with itself. Nothing off the shelf fit, so I built one over a couple of weekends. The tower metaphor was the part friends saw; the part that aged well was the sync model that fell out of needing the same state in three places at once.

 Spring 2016. I had a Raspberry Pi, a couple of 12V RGB LED strips someone had given me, a handful of MOSFETs from an electronics kit, and zero idea what I was doing. I wired one of the MOSFETs backwards and it got hot enough to leave a small mark on the breadboard. I learned to read a datasheet, slowly, by needing one. This was the first thing I started and actually finished.

 In November 2019 I wrote my own notes app for Android, used it daily for a while, and then it lost a long battle with Obsidian. The loss was the lesson: I learned what I actually wanted from a notes app by watching mine fail to be it. Years later that same itch is why I wrote [reconcile-text](/articles/reconcile-text-3-way-merge/); by then I was editing the same notes in Vim, VS Code, and Obsidian, and nothing existed to merge three independently-edited copies back into one.

 Trying to solve flow and heat as a coupled system would have been a real CFD problem and I had two weeks. A cybersecurity event in late 2018 needed a cooling-system simulator that contestants could poke at through PLCs over a weekend, and the deadline shaped every decision after it: cheap to compute, plausible to a non-specialist, runs all weekend on one server. The useful design move was modelling flow and heat as **two separate graph passes**, not one combined PDE.

 A user told me the map felt sluggish when they dragged it across Manchester with four filters on. They were right. The previous version round-tripped to a database, decoded floats, and lost the budget for a single pan inside the first filter. The rewrite is one Rust binary that holds the entire UK property history in RAM and treats every filter as three integer compares. Everything else in this post is the consequence of refusing to break that latency again.

Distance in colour space, not a brush. So I built the proof.

 I take walks with a camera. Most of what I shoot isn't good, but the act of walking slowly with a frame to think about is the most reliable way I know to come back with an idea for whatever I'm working on. In the summer of 2016 I wanted somewhere to put the few frames that survived, and I wasn't going to maintain a CMS for it.

 Autumn 2017, Basics of Programming, a deadline that forced me to learn C the hard way. I'd write almost none of it the same way today, and I'd defend every choice in it anyway. A 3D voxel platformer in pure C with SDL 1.2. No engine, no scripting layer.

 Winter 2020, BSc thesis deadline closing in, and the thing had to run acceptably on my advisor's laptop the day he graded it. That single shipping pressure exposed every lazy assumption in the architecture and picked the design: tile-based passes, deferred shading, shaders generated per scene and per device. A 2D ray tracer in the browser via signed distance fields: soft shadows, smooth reflections, no triangle mesh. The other half of the thesis was [decla.red](/articles/declared-shared-simulation-code/), the multiplayer game that proved the renderer survived a real game loop.

 I refuse to give up the editor. Obsidian on the phone, Vim on the laptop, VS Code at work, the occasional headless `sed` across the whole vault. None of them know about each other, none of them are going to learn to, and I'm not switching to whichever sync product picks a favourite. VaultLink is the architecture that falls out of that refusal: one Rust server, one TypeScript sync engine, an Obsidian plugin, a CLI, and two test harnesses. The merge primitive underneath it all is [reconcile-text](/articles/reconcile-text-3-way-merge/), which I wrote first. VaultLink is the question that made it worth writing, finally asked in earnest.
