I occasionally use mouse keys, but they're not good for rapid movements. I've always thought that I'd like eye tracking to quickly move my cursor. A few years ago, I bought a cheap Tobii Eye Tracker 5 on eBay. I assumed there would be a Linux driver for this, it's the 2020s! The future is not evenly distributed.

The device has two parts: an IR camera for head pose detection, and a built-in "EyeChip" which detects eyes and predicts where you're looking.

I've finally got both reverse engineered!

@timschupp I use Robotnix to build a GrapheneOS for my phone
I'm now trying to keep a branch active with the latest #NixOnWindows. I've got a demo here, which starts a tiny Windows VM with a cross-compiled Nix installed, from Linux: https://github.com/nix-windows/nix-windows-demo

@leonlion agenix and sops-nix provide a solution
Been using a branch of Battery Emulator for my home battery. It provides a totally new UI, which is powered via JSON and not hundreds of HTML strings concatenated together. Way faster. I'm more confident in this branch than the main one.
@deech I've compiled lots of things recently with Cygwin and MinGW (e.g. Nix, Bash, coreutils, etc) - I haven't had anything flagged.
Nix's CI now runs a few basic unit tests on Wine, ensuring progress to #NixOnWindows is not regressed! https://github.com/NixOS/nix/blob/ee955b3206ee3ef6e811a4960c2c15e5f1b5d09d/ci/gha/tests/windows.nix

I stayed back after work with two other people at Obsidian Systems to continue work on #NixOnWindows. It's so close to being useful! Most unit tests passing, I've even managed to do a few actual builds!
@tpolecat @arosien I've been running Meshtastic for a long time. It's only useful to myself because nobody is running nodes anywhere close to me, but it's good during outages and camping.

NEW: A Queensland software engineer has been in a four-and-a-half year long battle with Services Australia to get a look at a MyGov app's source code.

He says we should be able to scrutinise it to make sure it's secure. Services Australia says it's a national security risk.
