It was great attending the 2025 National Security Hackathon with team AMIS. Want to thank @cerebral_valley for hosting at @SHACK15sf, and the sponsors @StanfordGKC, @ShieldCapVC, IQT (In-Q-Tel), @scale_AI, @VannevarLabs, @NATO's innovation fund (NIF) as well as the data/compute sponsors our team used: @AnthropicAI, Code Metal, and @Maxar. I also want to thank all of the mentors that were there to help us define our project: a Maritime Intelligence System for anomaly detection using AIS data which we are currently building upon with other sources to detect AIS spoofing (ex. the Tae Yang incident), resource smuggling (ex. Houthi fuel smuggling before the Ras Isa strike), and other foreign Maritime activity.

I turned a dream that would’ve taken me 40 years to even start into a reality for my 21 y/o self in 3 months.

A thread on @elsewhere_today from idea to launch ⬇️

[Samantha Ouyang @samanthaaouyang]

When I moved to SF I was fed up with how every cafe was closed by 5

So we're building a place for the dreamers & doers after dark

Those who don't fit the conventional 9-5

It's slow but not enough for me to want to spin up a cluster.

They should make ASICs for builds.
