  • I don’t know. I’m thinking if you have one environment that’s cold, and one that’s hot, and interaction between them, then you have a cline extending between two extremes and therefore somewhere along that cline, you have the right amount of change for life to evolve.

    It’s basically the mean value theorem or something like that.

  • Skateboarding on multilevel o'neill cylinders is gonna be sick

    O’Neill cylinder is that big rotating cylinder space station format that uses the spin for artificial gravity.

    At higher elevations the gravity will be lower. BMX bikes will be fun too. Make a big jump and you can go across the center and land on the other side, or go into a zero-gee part in the middle, which works out if you’re always inside a curve.

    Sleep is when your brain's LLM retrains on the day's conversation

    I’ve noticed ChatGPT gets less able to do precise reasoning or respond to instructions, the longer the conversation gets.

    It felt exactly like working with a student who was getting tired and needed to rest.

    Then I had above shower thought. Pretty cool right?

    Every few months a new ChatGPT v4 is deployed. It’s got new training data, up through X date. They train up a new model on the new content in the world, including ChatGPT conversations from users who’ve opted into that (or didn’t opt out, can’t remember how it’s presented).

    It’s like GPT is “sleeping”, to consolidate “the day’s” knowledge into long term memory. All the data in the current conversation is its short term memory. After handling a certain amount of complexity in one conversation, the coherence of responses breaks down, becomes more habitual and less responsive to nuance. It gets tired and can’t go much further.

    McDonalds hasbrowns

    I just stopped at McDonalds and ordered two orders of hash browns. I expected to get four “patties” of hash browns, but only got two. Each order has one big oval shaped chunk of hash browns.

    I asked the guy about it, asked when it had changed, and he said it’s always been that way. I searched google images, and all the pictures show a single chunk to an order.

    Does anyone else remember an order of hash browns being two separate pieces?

    For me this changed in like the last week because the last time I got an order with two in it was a week or two ago.
