Infosec, Psychology+SE, OSINT, Privacy, Planes (), NJ, 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...
