  • Cast iron is pretty good at almost everything, but isn’t the best at anything.

    For searing meat at high temps, I’ve settled on stainless steel. It’s easy to clean and maintain, and the typical 3-ply or 5-ply cladding has much better heat transfer characteristics than cast iron (which is a mediocre heat conductor masked by the fact that it’s so heavy and thick that it takes on a lot of thermal mass to aid in searing). You don’t have to worry about metal utensils or harsh scrubbers scratching the surface. And you don’t have to worry about acidic ingredients messing with the surface, either.

    For things that need nonstick characteristics, like eggs, I cycle through nonstick on a short replacement cycle (once every 2 or 3 years). I might get a carbon steel one day but I’m not in a hurry.



  • Does that actually add up, though?

    Google released stats recently that the median Gemini prompt consumes about 0.24 watt hours of electricity.

    For humans performing knowledge based labor, how many prompts is that worth per hour? Let’s say that the average knowledge worker is about as productive as one good prompt every 5 minutes, so 12 per hour or 96 per 8-hour workday.

    Let’s also generously assume that about 25% of the prompts’ output are actually useful, and that the median is actually close to the mean (in real life, I would expect both to be significantly worse for the LLM, but let’s go with those assumptions for now).

    So on the one hand, we have a machine doing 384 prompts (75% of which are discarded), for 92 watt hours of energy, which works out to be 80 kilocalories.

    On the other hand, we have a human doing 8 hours of knowledge work, probably burning about 500 calories worth of energy during that sedentary shift.

    You can probably see that the specific tasks can be worked through so that some classes of workers might be worth many, many LLM prompts, and some people might be worth more or less energy.

    But if averages are within an order of magnitude, we should see that plenty of people are still more energy efficient than the computers. And plenty aren’t.










  • Generally speaking, health insurance through employment are priced at 3 levels of service:

    1. Self
    2. Self plus one
    3. Entire household

    Generally speaking, each additional person is cheaper than the last additional person. So option 3 is almost always the cheapest per person, with option 2 being pretty cheap per person, and option 1 being the most expensive per person.

    That fact is obscured by the fact that generally speaking, employers only give a diminishing subsidy so that they’re covering less and less as you add more people to the plan.

    So if option 1 is $250, and option 2 is $400, and option 3 is $500, maybe the employer will contribute $200 for option 1, $250 for option 2, and $300 for option 3 so that your portion of the premium is $50, $150, and $200.

    Also the reason why insurance is cheaper per person when a bunch of people bundle together is because there’s less risk of each covered person being really sick, and more likely that it’s just one person in the family who needs a bunch of treatment, so the higher out of pocket max tends to make the per-person cost cheaper for the insurance company, and therefore for the person paying premiums.




  • It was just a dominant brand of dishware in the U.S.

    Corning, one of the world leaders in glass manufacturing and materials science, figured out how to make thin tempered glass that was lightweight, very durable, resistant to thermal shock, and safe to use in microwaves, dishwashers, and up to medium temperature ovens (350°F/175°C is the manufacturer recommended max). It became the dominant dishware brand in the U.S. as a result, for “everyday” use.

    Personally I don’t like the heat transfer characteristics (poor insulator which means hot food makes the dish hot to the touch) and don’t mind thicker plates/bowls for most situations. But I can see why they became immensely popular, especially for families with kids.

    Side note, Corning spun off its consumer products division in 1991, so the company that makes the Gorilla Glass in basically everyone’s cell phones is now technically different from the company that made all these kitchen dishes, even if they were once part of the same corporation.


  • still 150 is a scary amount for most Americans to see just suddenly charged. Even if its temporary.

    Think of it as not even being charged. The hold/pre-authorization is just there to make sure that it can charge you that much if it needs to, but it never actually does charge you. It just tells your bank/card issuer that it might want to charge you up to that much.

    Hotels and rental cars do this with huge amounts, too, to make sure that they can charge you for the stuff you charge to the room or if you keep a rental car for an extra week. But you don’t actually get charged for it until the merchant determines you did use those extra services for those extra charges.


  • The best selling vehicle model in America is the Ford F-150, with gas tank sizes mostly above 30 gallons (exact size depends on model/options). The second best selling vehicle is the Chevy Silverado, whose gas tank is between 24-28 gallons.

    At $3/gallon, that’s between $75 and $90 for the typical fill up.

    For some vehicles (really large SUVs, premium SUVs that take premium grade gas), I can see $200+ tanks at certain gas prices we’ve seen in our recent past.

    So it makes sense for a gas station to do a pre authorization for $100, maybe $150.

    The other thing, too, though, is that the hold/pre-auth doesn’t matter if it’s a credit card that you just pay at the end of the month. It gets sorted out before your statement balance gets billed to you. It can get annoying if you’re using a debit card and your balance is low, but this is just another way that credit cards tend to be better than debit cards if you can handle the responsibility.
