Just a little play on the recent HN post: https://news.ycombinator.com/item?id=46016902

Project that I did a few years ago. You might also be interested in the retrospective where I detail what all went wrong: https://blog.nns.ee/2025/04/01/modem-blog-retrospective/

That’s pretty awesome

Isn’t such an old kernel dangerous for hosting though?

There was also work to replace the modem OS wholesale: https://hackaday.com/2022/07/12/open-firmware-for-pinephone-...

That would, I expect, help with the unfortunately old kernel version and generally give greater confidence in what's running on the second computer inside the computer.
