Train Rule
  • I was slightly wrong. From page 237 of Algorithms to Live By, The Computer Science of Human Decisions by Brian Christian and Tom Griffiths, further referencing the paper How Bad is Selfish Routing? by Roughgarden and Tardos, it says that

    "...the "selfish routing" approach [of cars] has a price of anarchy that's a mere 4/3. That is, a free-for-all is only 33% worse than perfect top-down coordination."

    Anyways, the way they got to that number is mathematical game theory. In this case people will choose the fastest route which happens to not be so bad.

    It's also very possible that what they're concluding is significantly abstracted, but I haven't read the source reference to know for sure.

  • I read in a book that the current system of drivers acting on their own without something coordinating their every move is actually 75% as efficient as a fully coordinated system.

    Therefore, the benefit obtained with all people using self driving cars is nothing compared to just improving public transit or improving car infrastructure.

  • Suddenly seeing more hexbear posts. Did we re-federate with them?
  • I think this is a great example of how federation allows you to make an account somewhere else....

    Just make an account in an instance that defederated hexbear. Even if an admin is an idiot they'll know to take action if the user count begins to stagnate or fall.

  • Megathread for Reddit Blackouts and News - Day 2
  • Not to mention, it doesn't feel like the blackout did anything either. I opened up r/all on Sync just now and it didn't feel any different than it did a week ago besides a bunch of posts that say that Reddit is killing 3rd-party apps.

    I really hope that spez stops being such a dickwad. I mean, I understand that Reddit is probably in the red but you can charge more for API usage without accusing a 3rd-party dev of blackmailing you and outpricing literally everyone.
