Claude writing a macOS driver for my obscure HP printer built only for Windows

I have another controller-related anecdote.

I have a Razer Wolverine Xbox controller that has extra back paddle buttons. The controller doesn't expose the paddles directly to PC's over USB. You have to use button remapping on the controller to map them to 'real' Xbox buttons for the PC to see them. But I wanted to use the back paddle buttons on Steam as separate controls.

So I downloaded the latest firmware update off the internet (because what device doesn't have firmware updates these days), installed Ghidra and an MCP server for it, and told Sol to look for how I can expose these extra buttons to a PC host. Maybe we could write a firmware patch?

Turns out the controller already has a special mode to expose those buttons, possibly as a hardware test. But it was enough to write a Linux driver to put the controller into that mode, and a little bit of extra driver code to map the paddles to a Linux controller button, and voila. Paddles working in Steam.

And it only took a few hours to do, too. I spent more time making an open source repository out of the concept than I spent making it work.

Recently, I had bizarre situation: I wanted to play a game from my childhood on Windows 11, but, without changing two booleans in the settings, I could not reliably move my in-game cursor. The catch is that to change those values in the settings, I needed to move my in-game cursor. So I was stuck.

After digging around, I found a file that looked like it could be the settings file, but it was not plaintext.

Naturally, I told Claude all the options I knew existed in the settings and told it what I needed it to change.

After about 10 minutes poking around my system and the file, it correctly identified the bits (not bytes!) that corresponded to the two settings, and flipped them on. It. Just. Worked!

(Well, then I found out I actually needed to do quite a lot more than flipping those bits, but I still found it worth sharing).

I have many more experiences similar to these. LLMs are an amazing superpower.

I have a similar experience. I'm playing minecraft lately and I have patched already like 5 issues in the server that I would never put together time to trace/debug/understand/fix, including some o(n^3) integration between mods that was lagging the server. Same thing for utilities, managing backups, etc.

I love seeing things like this. Is it not kind of a magical thing to see AI make stuff like this reality? This was always possible but not worth a human’s time. Now this guy has a working printer again. That’s pretty doggone neat.
