I used plenty of non-agentic AI to help understand the XNU codebase, and also research various topics. It wasn't always correct, but it certainly helped at times! My philosophy for this project was to use it as a learning tool - since that was kind of the whole point of me attempting this :)

looks like they did use AI, swing and a miss for the luddites once again!

Ah, the Procrustian definition of "real hacker", where using AI disqualifies you but using Github pages is considered only a minor infraction.

The build-in-public era of hacking has really turned this field into an influencer economy.

I probably have rose colored glasses, but this is what I associate with Hacker News when I first started coming to this site. Truly absurd projects for no reason other than the love of the game and detailed write ups.

I'm not an LLM post hater, but it definitely has been a bit draining lately. This is exactly what I love to see here.

Get to submitting! Be the change you want to see.

I’m SOO happy but also wistfully sad when I open a post like this that I am desperately excited to read and it’s not muddled-thinking- and LinkedInese-riddled slop.

I bet there's some way to make the GPU do the color conversion. It's not like it's doing much otherwise...

Last I checked, the 60fps frame buffer conversion resulted in the system idling at 18% CPU. Certainly not ideal. I'd love to optimize this further.

This solution’s COU cost can be significantly improved by using memory protection. You protect the frame buffer from writes. The first time it is written, you take a fault, and start refreshing every 60 Hz and leave it writeable. After some number of refreshes, you protect it again, the idea being is that the UI may now be quiescent. I do this in my Palm OS port for the same reason.
