I attended the H.O.P.E (Hackers On Planet Earth) conference this past July in New York. Interesting speakers with talks on a wide range of subjects including : Smart Cities and Blockchains: New Techno-Utopian Dreams or Nightmares?, Chinese Mechanical Locks – Insight into a Hidden World of Locks, Crypto War II: Updates from the Trenches and many more. I recommend a trip to the next HOPE conference in 2018. If interested in the subject matter I suggest taking a look at 2600 magazine and a listen to Off the Hook. The magazine and radio show of the organizers of the event.
