Great. Let us hope that support for hardware without TPM is next. Creating several mountains worth of electronic waste was a terrible decision. And in the middle of the AI-induced memory shortage! Although I have to admit: The combination o

[I'm still thinking about this a day later!] I think an additional table/graph of how large-bet performance vs small-bet performance would be interesting in general, as well as broken out by market type. It kinda answers of the qu

Something that appears to be missing: Certain events attract "advertising" types of bets. E.g. There is value in making a candidate appear to be a leader, so dedicating dollars to swinging the market is more of a form of advertisi

I would guess that someone is beaming a whole lot of wideband power at the satellites themselves, to overload the input receivers.

Maybe they could add a helpful paper clip to improve sales. Edit: Or better still, convince all of their customers to throw away perfectly good hardware and upgrade to one with a single extra chip, creating a hazardous waste epidemic for la

Hold a chain at its ends, and let it hang down naturally. What is that shape called? A catenary and its equation is y = a cosh(x/a). Maybe you all knew that factoid already, but I learned the name of shape only recently.

Perhaps, but "Mathematical Physicists HATE when authors make THIS ONE ASSUMPTION!!1!" would be more click baity. I took it more as Baez writing for his physics audience.
