45 years for me. I don't even think about keystrokes anymore.

> and they get to join the index next year without a rule change. You seem to have ignored the 50% float rule. SpaceX is proposing to go public with about 5% of the float, but S&P …

Manias, Panics, and Crashes by Charles Kindleberger is a more modern book, which I'd recommend as well.

> Then I see he links to his own Revolutionary Theory, and it starts to look like outright crankary. But what an AI-generated crankery! Because I enjoy wasting my time, I chose a r…

In fact, you had to pay extra to have your number/address omitted from the phone book.

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 …

I think the most intriguing part of this effort: Farmers traditionally employ machines to achieve their harvest. Unless I'm mistaken, this is the first time that machines are emplo…

[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 bro…

> but i did find that politics was actually one of the most efficient categories (only ~1% maker/taker gap) I confess I'm surprised by that result in particular. I realize your res…

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 …

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 s…

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 …

> worry instead about stroke. You say that as if stroke is orthogonal to heart disease. Much of what prevents one prevents the other.

> Although I’ve never had a boss that needed to find an error. I think that is key. A great mentor early in my career pointed out to me: "A" rated people need to work for "A" rated…

How do you deal with the short lifespan until EOL? I've been using Rocky (and CentOS before that) simply to avoid dealing with EOL so often.

Like many of you, I serve as IT support for family. Some of those family are beginning to slip cognitively, so I'd like to say: Fk google for doing this. You are confusing my relat…

And just like that, there was a mad rush of mass-spectrometer-for-home-use startups.

MIT has a long tradition of hacks, and among the first documented hacks in the 1870s for marching practice: > in which students sprinkled iodide of nitrogen over the grounds of a m…

Back in graduate school, I TA'd an electrostatics course. We were going through the details of the basic parallel-plate capacitor, and so Prof. Peter Hagelstein (of the project you…
