Ryan Castellucci (they/them) nonbinary_flag (32)

At I used

✅ Toilet for Women only
✅ Toilet for Men only
✅ Toilet for trans/nonbinary/intersex only
✅ Toilet for all genders

and nobody noticed or cared 🤷

(for those who did not attend, the vast majority of the toilets were "for all genders")

To round off my experience, I ended up on the same flight as a friend, and another Congress attendee who was with that friend ended up next to me. Now I have a new friend!

My Star Trek uniform was a bit too warm, so today I'll be wearing my purple "Fuck Bitcoin" tshirt.

I still have hexadecimal dice for anyone who wants one and talks to me. I will probably mostly be near the hall h sos stage in a bean bag chair after this talk, though might divert for a bit for the cheating at ctf talk.

I do network forensics and bot detection professionally, and otherwise a bit of applied cryptography (build and break), bureaucramancy (gdpr application, taking the british government to the european court of human rights for gender, basic stuff), cursed hacks, computer adjacent art, and queer stuff.

Wearing my starfleet uniform (tng, operations gold) until it gets too warm, and a red eff tshirt.
