Cybersecurity weather person and award winning shitposter. Shitposting is an anagram of Top Insights. You may be surprised to know I am not representing my employer here and these are not their opinions.

I have Direct Messages disabled - you can send them, but I will never receive them.

Used to help run Fosstodon. These days, I just hang out here.

I work in InfoSec and live with two kids, one wife, two dogs, a blind cat, a flock of 25 chickens, 8 goats, and more fish than I can count.

Also into watches and motorbikes — both riding and wrenching.

I also run @purecommons.
