  • It’s semantics, but I think the person above is just pointing out that “AI” is an old umbrella term that refers to a lot of technologies that include previous current and future work, and shouldn’t necessarily be bound forever to one era’s misapprehension and misuse of a particular subset of those technologies.

    Prior examples of AI included early work by Alan Turing. Current examples include tools that enable people with disabilities. Future examples might offer solutions to major problems we face as a society. It would be a shame if use of a term as a buzzword was all it took to kill a discipline.


  • That’s an apt example from English, especially given the visual similarity of the error.

    It’s the kind of error we would expect AI to be especially resilient against, since the phrase “corner cube” probably appears many times in the training dataset.

    Likewise scanning electron microscopes are common instruments in many schools and commercial labs, so an AI writing tool is likely to infer a correction needed given the close similarity.

    Transcription errors by human authors, however, have been dutifully copied into future works since we began writing stuff down.


  • There was a comment yesterday that offered a simpler explanation than the headline’s conclusion.

    The papers were published by Iranian researchers and in Farsi “scanning” (روبشی) and “vegetative” (رويشی) differ only by one character (ب and یـ) which also happen to be adjacent on the keyboard.

    That is, there’s some evidence that this is a typo or mistranslation that has been reused among non-native speakers, as opposed to a hallucination. If so, it could still be a LM replicating the error, but I’ve definitely seen humans do the exact same thing, especially when there’s a strong language barrier.

    Edit: brevity




  • The difficulty was drainage. Isolated steam systems in steam era construction were designed to use gravity for condensate collection. It’s one of the reasons boilers are always in the basement of old buildings.

    Steam system engineering was a well-compensated profession. A well-designed system would accurately predict the rate of condensate flow for every part of the building, prior to construction, and reflect these predictions in the slope/grade and diameter of the steam pipes. Inaccurate predictions resulted in problems like pipe knock (aka steam hammer) which you can often hear when you or a nearby neighbor partially close the shut-off valve of a radiator.

    Since construction in the city had many elevations and could not be predicted in advance, there was no equivalent solution to facilitate condensate collection. The system had to be one way. And yes, it’s inefficient compared to modern systems, but was innovative in its day.




  • That’s a good idea! My understanding is that the old steam network is slated for decommission and replacement by this program, basically a large distributed geothermal heat pump network that also harvests from major heat producers like data centers and provides both heating and cooling.

    It will end the era of the steamy-street Sin City aesthetic but should be many, many times more efficient than the old steam system. Phase-change thermal transfer in HVAC systems is nearing 400% efficiency, so 4 times more efficient than the theoretical limit of direct heating, because it only uses the energy necessary to move heat from one place to another rather than produce it, and it works for both heating and cooling.

    Right now I believe they’re piloting the system in NYCHA buildings (public housing) of neighborhoods outside the old steam network, like Chelsea and Hell’s Kitchen, but supposedly the plan is to expand to the rest of Manhattan.

    Edit: corrected coefficient of performance







  • He’s making a point about instantaneous versus overall energy use, which it sounds like you already understand. “Power” and “energy” are kind of loose terms IMO, which could confuse that conversation a bit.

    But for anyone still scratching their head:

    The typical energy consumer need only consider watts (w, kw) when accounting for circuit capacity. For example, if your hair dryer pulls 1600 watts, don’t use it on a 1500 watt outlet, or you will likely trip the circuit breaker.

    Otherwise “watt-hours” (wh, kwh) is likely the metric you’re looking for when considering energy use. This is a certain amount of power drawn over a period of time, where 1 watt over 1000 hours and 1000 watts over 1 hour are both equal to 1 kilowatt-hour (kwh), which is the standard unit you likely see in your electric bill.

    It’s why low but constant power draw can significantly impact energy use. For example, a typical laptop pulls fewer than 100 watts, lower than many appliances in your house, but if it draws that much power all the time, it might significantly impact your electric bill. Conversely, an electric kettle / coffee maker might pull as much as 1300 watts while in use, more than most appliances in your house, yet it probably represents a minuscule portion of your electric bill, since it only runs long enough to boil a small amount of water with each use.

    Edit: include tea drinkers, add more concrete examples






  • Edit: preemptive “no you”lol

    To be understood, I’d probably just say projection, but if you need to emphasize a specific aspect of the behavior, we could break it down as:

    1. an existing insecurity or shame that
    2. prompts momentary social anxiety
    3. evidenced by a defensive impulse
    4. to preemptively introject

    Explanation: introjection refers to a mirroring behavior, the kind often seen in children. In this case, the accuser anticipates an accusation from you which threatens or hurts them. To defend themselves, they hurl the accusation right back at you. But of course the first accusation only happened in their head, so all we witness is someone wildly accusing someone else of having their own flaw without any justification.
