@[email protected]Interested in All Of The Things.
Things I do: landscape, storm and protest photography, paragliding, climbing, border and human rights activism.
Intellectual hobbies I watch from the sidelines: science, security/privacy, online sociality and general internet theorizing.
You can write to me via my website, though Signal gets the quickest response.
Welcome newcomers. You'll like it here, but give it some time.

I once worked with goats. I moved into tech.This was a mistake.
Expect sheep, wool, and textile history. Also birbs. Infosec on occasion.
I use content warnings for topics and images that can trigger PTSD. I do not use them to shield people ***without*** trauma from experiencing racism, sexism, transphobia, and other forms of discrimination. If you can ignore politics, you’re not likely in need of content warnings for much of anything, really.

@[email protected]Header image is a novelty desk sign that, instead of a name or title, reads "Welcome to the shitshow," nicked from someone here. Avatar is a selfie of me standing up, outside, with a neighborhood of palm trees and stucco houses behind me. I'm wearing light sunglasses, red lipstick, and a sleeveless shirt with a balloon animal print. Not shown: my walker. #IIH #IdiopathicIntracranialHypertension #fibromyalgia #disability #TransRights

Huge SciFi fan 🖖
Just a cold robot on the internet hacking, shitposting, helping and doing things
I joke. A lot.
I post about planes and ATC stuff. A lot.
Pretty unfiltered, thoughts/opinions my own not my employers. Probably overanalyzing things... Or am I? What does that really mean? Maybe if I calculate the optimal amount of analysis...
