eta is a phenomenally talented polymath, hacker, and computer programmer from the UK. Today eta joined us to discuss her very fun project reverse engineering UK rail tickets. This was a fun event with a reasonably big audience and lots of Q&A, and we really enjoyed it! It was also a good example of the best possible outcome in hacking: you break something, you tell the people who made the thing, and they give you a high-five and fix it. Thank you so much eta for speaking to us! To learn more about eta's work, refer to her website here: https://eta.st/
