  • I’m not sure that’s even a valid comparison? I’d love to know where you got that data point.

    LLMs run until they decide to output an end-of-text token. So the amount of power used will vary massively depending on the prompt.

    Search results on the other hand run nearly instantaneously, and can cache huge amounts of data between requests, unlike LLMs where they need to run every request individually.

    I’d estimate responding to a typical ChatGPT query uses at least 100x the power of a single Google search, based on my knowledge of databases and running LLMs at home.



  • A quadratic function is just one possible polynomial. They’re also not really related to big-O complexity, where you mostly just care about what the highest exponent is: O(n^2) vs O(n^3).

    For most short programs it’s fairly easy to determine the complexity. Just count how many nested loops you have. If there’s no loops, it’s probably O(1) unless you’re calling other functions that hide the complexity.

    If there’s one loop that runs N times, it’s O(n), and if you have a nested loop, it’s likely O(n^2).

    You throw out any constant-time portion, so your function’s actual runtime might be the polynomial: 5n^3 + 2n^2 + 6n + 20. But the big-O notation would simply be O(n^3) in that case.

    I’m simplifying a little, but that’s the overview. I think a lot of people just memorize that certain algorithms have a certain complexity, like binary search being O(log n) for example.








  • That doesn’t seem worth it when you can fit that amount of storage in about 20 L with lithium ion cells (think a small PC case), or something like 40 L if you used sodium ion cells, which are looking like a new alternative.

    Concrete offgassing of CO2 is already a big contributor to greenhouse gasses, so I can’t imagine this battery version is improving things there. You’d probably have to wire your whole basement with electrodes to even access the stored energy.

    I’ve had the audio desync in cutscenes after leaving a game open in sleep for a week or two. I think it’s an issue with how the game timers work. If they’re counting since the game started, any slightly inaccuracy will become more obvious as the game is left open, regardless of sleep.
