It’s pretty simple to do this with tailscale + x11vnc. SSH keys On local: ssh-copy-id remote and enter the… Read More

A story about a raspberry pi laptop Once upon a time I was excited about typewriters. Wait a minute, I am still excited about typewriters. Once I was excited about typewriters, but also computers. I knew I liked the immediate typing experience and the “nothing can interrupt me now” flow of having one and only… Read More

On my new pi laptop (to be described in a later post) it always boots to console without numlock. I would prefer numlock to be ON always. Raspbian GNU/Linux 10 (buster) Working directory /home/pi/Dev/ Script setNumLockOn INITTY=/dev/tty[1-8] for tty in $INITTY; do setleds -D +num < $tty done Service setNumlock.service [Unit] Description = Set numlock… Read More

But sometimes it hangs and then tells you that the packages you are trying to install won’t work together–but not exactly WHY. I spent much of the day trying to debug a… Read More

I have wanted to try blacksmithing since I was a kid. Yesterday I finally got a chance to do that. My setup is a propane tank, 6 firebricks, and a piece of railroad track. I had to cut one of the bricks. I scored it with the angle grinder and then snapped it over the… Read More

I previously built a Roubo phone stand that gets used all the time. But phonestands are so useful that I have more. A lot more. I designed this one in OpenSCAD, a free text-based CAD program, and it is fully parametric. You can adjust the size and the angles to ridiculous degrees. But this is… Read More
