Hacker News Discussion

📝 Discussion Summary (Click to expand)

Four prevalent themes in the discussion

  1. Perception of DefCon’s political culture
  2. Schlagbohrer called DefCon “extremely right wing misogynism,” while many respondents disputed that characterization.

  3. “Having been to defcon a number of times, I truly have no idea what you're talking about.” – FL410

  4. “Can you elaborate? I thought a lot of LGBT people attend regularly?” – drbscl

  5. Ticket accessibility and event logistics for CCC

  6. Commenters noted the difficulty of obtaining tickets to the main congress, the ease of smaller local events, and the reliance on volunteers or hackerspace allocations.

  7. “Nowadays, most tickets go to hackerspaces and volunteers but the open sale sells out in seconds.” – pepperoni_pizza

  8. “If you live in Germany and would like to experience this on a smaller scale THIS WEEKEND, come to the CCC conference in Dresden… Entry is completely free of charge.” – pid0x17

  9. Inclusivity versus exclusivity of the CCC community

  10. The scene was praised as family‑friendly and artist‑rich, yet also described as a closed circle with longtime “old‑schoolers” benefiting from backchannels.

  11. “It is a beautiful and inclusive environment that highlights not only a lot local hackers, but also a lot of artists.” – pid0x17

  12. “There are some token newcomers, but overall it is a very closed community.” – pepperoni_pizza

  13. German/European privacy and photography norms vs. US expectations

  14. A lengthy subthread debated the legality and etiquette of photographing people at CCC, contrasting German sensitivity to public‑sphere photography with a more permissive US attitude.

  15. “Just remind them, public photography is not a crime, and that there is no right to privacy in the public sphere…” – MomsAVoxell

  16. “Photographing at CCC events… is permitted only if you get permission from all the people depicted on the photo.” – seba_dos1

  17. “Yes, Germany absolutely has a right to privacy in the public sphere… if you point the camera at a person you need their consent.” – wongarsu
