Did you ever waste a whole day tearing apart hardware and rewriting your drivers to figure out why your firmware was getting corrupted when transferring it to your hardware device, only to discover it was a broken compiler on the host generating garbage and everything was transferring that garbage just fine all along...

I discovered by accident that Thunderbolt 3 magically works in OpenBSD on my X1 Nano.

I plugged in a Thunderbolt NVMe enclosure to check whether it would fall back to USB attachment, but ppb, pci, and nvme devices attached. I verified with an Apple Thunderbolt 2 ethernet device (through a Thunderbolt 2 to 3 adapter) and it also attached as bge0 as expected, and detached properly when unplugging.

My previous tests with Thunderbolt on other OpenBSD laptops only worked when the devices were plugged in at boot time, since the firmware had to setup the device. I'm not sure whether something changed in OpenBSD or the EFI firmware that makes hotplugging work now without a Thunderbolt NHI driver, but I'll take it.

The best kind of drivers are the ones that don't have to be written :)

I've used Reddit for 17 years and was on Twitter for 15 years and it's surprising how quickly they both imploded relative to their lifetimes, but also how little it bothers me to suddenly stop using either of them.

That's probably a good indication that I was consuming too much wasteful content on them every day and this is for the better.

Though I'm really sad to see @christianselig have his hard work shut down with no recourse, especially seeing how much he enjoyed working on Apollo over the years.

I wonder how big of a project it would be to replace the guts of the Palm Modem with an ESP8266 and have it do PPP back to the Palm for WiFi

The software would be easy but I am not so good with the hardware side
