My old 2017 Huawei MateBook X has been my most reliable laptop and has 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 would look bad, or the fan or some coil-whine noise would drive me nuts. And every time, I’d return to my MateBook X and everything would just work silently. ⌘ [Read more](https://jcs.org/2021/08/20/matebook) 2021-10-22T05:00:00Z **Video: C Programming on System 6 - Amend Revision Control System**

I started using the Tindie platform in April to sell my WiFiStation kits. I’ve now sold out all of my initial inventory and am not planning on making any more, so I thought I’d offer my opinions of Tindie as a platform for selling things. ⌘ [Read more](https://jcs.org/2021/11/15/tindie) 2021-12-01T06:00:00Z **Video: C Programming on System 6 - A Cooperative Threading Library**

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.
