Live Streaming a Macintosh Plus (or Any Compact Mac)

posted on feb 21st, 2022 with tags openbsd and retrocomputing, and last updated on mar 26th, 2022

Since recording a handful of C Programming on System 6 videos, I’ve occasionally wanted to live-stream the more casual daily programming being done on my Macintosh Plus. After getting all of the pieces together, I now have a working self-hosted broadcasting setup.

If I happen to be programming on my Mac right now, you can watch here at my website.

Debugging an ioctl Problem on OpenBSD

posted on feb 16th, 2022 with tags debugging and openbsd

I was trying to use a V4L2 Ruby module on my OpenBSD laptop but ran into a problem where sending the V4L2 ioctls from this module would fail, while other V4L2 programs on OpenBSD worked fine.

Since I got a few questions recently about kernel development and debugging, I thought I’d write up how I finally tracked it down and fixed it. (Spoiler: it was not an OpenBSD problem.)

It’s a new year and my old computer is still old.

A bug in Amend caused it to crash during a commit, which corrupted the repo beyond repair. I quickly came to realize that using resource files as a database for Amend and my new BBS was a bad idea. I NIH’d the problem and created my own file format that will be a bit more resilient to crashes and partial writes.

OpenBSD on the Huawei MateBook X (2020)

My old 2017 Huawei MateBook X has been my most reliable laptop and continued to be my daily-use workstation despite trying half a dozen others (and a desktop or two) in the past four years. Every time I’d try a new laptop, certain components wouldn’t work properly, or the keyboard would feel strange, or the screen quality would be poor, or a constantly-running fan or some coil-whine noise would drive me nuts. And every time, I’d return to my trusty MateBook X and everything would just work silently.

I finally have a newer model of the MateBook X and I’m happy to say it lives up to its predecessor and has replaced my 2017 model.
