Ask HN: Can you recommend some 33c3 talks?

I found this one very interesting, about using ultrasound for tracking

I think it was also on HN a few days ago..

In no particular order I found these quite I interesting:

Dieselgate – A year later

Where in the World Is Carmen Sandiego? (Hacking flight tickets)

Visiting The Bear Den (cyber espionage)

Welcome to the Anthropocene

Shining some light on the Amazon Dash button (Super advanced Hardware hacking skills on the dash button)

I liked and recommend "The Transhumanist Paradox"
