My prépa TIPE in 2009 was about surface acoustic wave touchscreens, with two simulators (a CUDA version on the GPU and a C plus SDL plus OpenMP version on the CPU) and a real experimental rig that classified 9 positions out of 9 with a centimetre of precision. In April 2026 I dug through a NAS backup of my old XPS desktop. The CUDA half is gone. The CPU half survived. This post is the post-mortem: what the project was, what was built, what was lost, and what it took to bring the surviving half back to life on SDL 2.

Why I built a Tauri 2 app to drill the 40 Gokyo no Waza on my phone every morning. I did judo as a kid, stopped for twenty years, restarted in a club in Canada, and discovered that my body remembered the throws while my mouth had forgotten the names. So I shipped a quiz I would actually open daily, the way I have been shipping software for ten years.

Turning a 1.91 inch AMOLED dev board into a multi-page bathroom display for weather, power, and (yes) my toothbrush. Driven by ESPHome, a mmWave presence sensor that also runs the lights, and a handful of I2C sensors.

Touch is one of our earliest and most intimate senses, yet we know remarkably little about its quirks. Optical illusions have entire museums. Haptic illusions have a GitHub repo and a 3D printer.

A complete breakdown of every service running in my homelab, organized by category. Over 40 services covering productivity, media, home automation, AI, monitoring, and more.

How I use Komodo as a self-hosted GitOps control plane to orchestrate 30+ Docker stacks across a Proxmox cluster, with automatic deployments from a self-hosted Gitea instance, network segmentation via OPNsense, and a NAS that doubles as an AI compute node.

How I replaced cloud-dependent security cameras with a self-hosted setup using Frigate, Tapo cameras, and an Intel Arc B580 GPU. No more false positives, no subscriptions, full data sovereignty.

Even if your company builds physical products, modern software delivery matters. Here’s how we use GitLab CI/CD with local runners across Linux, macOS, and Windows to ship faster, more reliably, and for every platform.
