I'm spending most of my time lately helping others with Linux #Kernel problems; previously for a wide variety of SMBs, ISPs, several #HFT firms, and a dozen state and national #USPol campaigns.

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...

Rust 🦀 | Linux 🐧 | Python 🐍 | Embedded ⏚
I’m an engineer currently writing and shipping production Rust for an anti-ransomware company.
I drink a LOT of tea, and read a lot of Sci-fi. I used to have many many hobbies including metal working, wood working, circuit design, 3d printing, you name it, but these days my most prominent hobby is anxiety.
I’m an American *and* an anti-fascist.
My avatar is a humanoid robot with a sword sheathed behind its back.

@[email protected]community. bikes. despair. send help
Give the land back. Back to the commoners and the commons.
Professionally:
EDU infosec. terrified. send thoughts and or prayers.
Previously: Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA). I know some stuff about how fresh water gets to your house, and how the poops escape.
Personally: read the toots.
i live on Payómkowishum land. What does it mean to acknowledge this? Where are the Payómkowishum? Is a relationship with them possible?
if i interact with you, its because i find you or what you post interesting, and want to be your friend. sometimes jokes dont land, or nuance is lost. we all deserve as much grace as can be given- at least until we are revealed to be monsters.
