Oh, man - Jeff is a giant in the raspberry pi and adjacent homelab and NAS spaces. I met him at events in the Drupal space, where he was a maintainer at the time, just showing off his first "bramble" (pi based kubernetes cluster). He is my favorite kind of open sourcer: genuinely curious with a love for explaining/helping people. Oh, and he's often on HN. Hi, Jeff!
I also knew him from then, back in my days of administering thousands of macs, his roles were a godsend.
Now I see him here all the time doing cool stuff with Pis and drives. I hope I bump into him one day, as our interests heavily cross, and he seems like a really nice guy.
