I made a WiFi module for the Cidco MailStation Z80 computer

Also, I don't get why Microsoft limits AMD models to the Ryzen 5 with only one color and small SSD, but if you just go through their small business store, you can opt for Ryzen 7 and 1Tb SSD

It seems weird to me that it has an AMD CPU/GPU but the WiFi is still Intel

With SMT enabled, you get 16 cpu devices which seems kinda crazy on a laptop:

cpu15: AMD Ryzen 7 Microsoft Surface (R) Edition, 1996.25 MHz, 17-60-01

Surface Laptop 4 Ryzen 7 (16Gb/1Tb) review after 15 minutes:
- Feels very MacBook Pro 2015; larger/heavier than it should be, big bezel, but good keyboard and quiet touchpad
- OpenBSD compatibility is nil; no keyboard, no battery status, no S3, amdgpu bombs, but iwx wifi works

I needed to monitor how far `gzip -d dump.sql.gz` was, long after I started it (without pv):

$ ruby -e 'loop do n = `fstat -o dump.sql.gz`.split("\n").last.split(" ")[8].split(":").map(&:to_i); printf("%0.2f%%\n", (n[1] / n[0].to_f) * 100.0); sleep 1; end'
50.68%

I guess if you don't update your app in many years, Apple will do an update for you to keep it running.

It took a while but I've finished adding closed captions to all of my C Programming on System 6 videos at
https://jcs.org/system6c for those that need them or just can't understand my mumbling.

WebVTT allows captions to be added to HTML video without Javascript, which is nice.

The spacebar on my X1 Nano was not always registering so I sent it in for repair on the 10th. I got it back today and they also replaced the battery and entire upper lid with display (including my rad OpenBSD sticker) despite these things working fine when I sent it in. Weird.

I've added a section to this article documenting how to use usbhidctl(1) and usbhidaction(1) to respond to Bluetooth headphone buttons which are passed through the BT-W3 as USB HID input reports

"We have the user-maintained programs directory. And there was even a mechanism to force their documentation. There was a cron script that was running and for any command that appeared there in binary that didn't have a manual page, it was deleted."
