I BOUGHT EVERY HORSE I'VE EVER SEEN
Up over 250 miles on the e-bike in the less than month since I got it, with stuff like this today. 😅
Very excited to get involved with Compu-Global-Hyper-Mega-Net as shown off by @CursedSilicon this past weekend at #teardown2026.

Come to this August 8! I'm *probably* going to bring my 1989 computer running a web editor, server, and browser again. https://pdx.social/@courtney/116977135325109506
Excited to be attending #teardown2026 here in Portland as usual. So lucky to have such a great conference and community right here at home. And major kudos to @helenleigh already for the work.

SUMMER 😍
Sorry to those affected by the wildfire smoke. It sucks. Real bad. Last year one of the times it hit us was my mom’s visit, when we had all sorts of summer outdoor plans. At least it’s making national news now.
So I've put 50 miles around town on my e-bike since picking it up one week ago, and most of that unassisted. To say it's a game-changer is an understatement.
Sold this today to a wonderful little family. Bittersweet, but too many wheeled vehicles, too many toys, and ten years was a great run. ✨
OK, now these catfishing attempts are just getting nasty.
