She/her/they
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.

Header image is a yellow selection button that reads "I'm looking for potatoes to eat," nicked from someone here. Avatar is me, a middle-aged cis white woman dressed in all black, sitting in a sauropod footprint fossil at the Carnegie Museum in Pittsburgh. I'm kicking up one leg straight out, and smiling hard with my white teeth showing and my dark eyes bugged out behind my dark-rimmed glasses.

Most posts auto-delete after 3 months, so grab that meme when you see it! :)

Infosec, Psychology+SE, OSINT, Privacy, Planes (#EWR), NJ/Lenapehoking, Linux, Geopolitics and Environmentalism etc.

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...
