The cursive thing is almost certainly because he's using fountain pens. Pencils and ballpoint pens lend themselves to printing more easily, because they require pressure to write, and when you let the pressure up between letters, the line stops. The first time I picked up a fountain pen and tried printing with it, I found all my letters were connecting whether I meant them to or not, and I suddenly understood why cursive exists. Everyone who's learned cursive in the ballpoint pen era has been unwittingly taught a performance optimization for a tool they're not using.
I don’t know whether you wrote this by hand in the most painfully LLM style you could gin up, or whether you got an LLM to do it for you, but either way I tip my hat to you.
Oh sorry, I didn’t mean to imply you didn’t. If you were lucky enough to get a doctor to diagnose you before you figured it out yourself, congrats. That should be more common than it is. There are way too many doctors out there brushing off obvious signs of small fiber neuropathy.
Autonomic neurologists are the relevant specialists. I invite you to look for one in your local area and see how rare they are. The last I checked, the Seattle metro area (and in fact the whole state of Washington) had precisely one board-certified autonomic neurologist. Diagnostic delay is, unsurprisingly, around six years. Combine that with the fact that all the equipment you need to do a basic POTS test is a pulse oximeter and a blood pressure cuff, and yeah, you're going to have people self-diagnosing, for good reason.
All of those may be correlated to the rise in obesity. I see no evidence that any of them is causal. I don't even think all of them are correlated, honestly. The rise in the number of calories available certainly is, but cars and suburbs have been around longer than that. And the rise in calories may just be a response to increased demand.
What evidence do you have that it is a cultural shift, rather than, say, a chemical in the environment that wasn't there before, or a difference in the food supply?
If you're not vegetarian, I recommend looking into heme iron. It's a lot more bioavailable, even more than iron bisglycinate, and in my experience it's much easier on the GI tract.
Yes, exactly. I don't object; it's salutary to find out you don't know anything about topic X. It's just disconcerting after having read and understood an article purporting to explain topic X.
Do you mean “simpler” or do you mean “more accurate”? I’m quite willing to accept your explanation as more accurate, but it is not simpler, at least if you don’t know much about modern cryptography. To understand the article, all I needed was some algebra. I think my 13-year-old could mostly get it. To try to understand your second paragraph here, I’ve spent about fifteen minutes so far looking things up (starting with the definition of “block cipher” and ending somewhere about halfway through the Wikipedia article on AES) and I have a sense of its meaning in the abstract, but if there’s a quiz tomorrow I’m in trouble.
If you really were going for “simpler” rather than “more accurate” then I regret to inform you that you have joined the “monoid in the category of endofunctors” guy in room 2501 of the xkcd building.
I read and understood the article, including the math in it, then came here (I know, that’s the wrong order) and read your comment, and promptly decided I knew less than I did before I started. It was very much like learning to use a monad in Haskell without knowing category theory, and then reading an article about them. Just because you understand an article written for the educated general public doesn’t mean you have the vocabulary to understand experts speaking to other experts.
I have a decent intuition for what a hash function does after twenty years of encountering them in the wild. I don't even know what a block cipher is. I understand hash functions less after reading this than I did before. My conclusion is that a hash function is just a block cipher in the category of endofunctors.
I disagree with most of this. I'm kicking and screaming pretty hard, and yet I'm not one of the "I can do it better" folks. My whole career has been in open source. I'm all about choosing the right tool. I'm also tech lead on a team of seven, so I'm not writing a lot of code anyway. What I am doing all day is sending AI-generated code back to be rewritten, rethought, re-architected. I'm starting to think we would get more done if nobody on my team used Copilot.
There's a reason AI uses things like em dashes and parallel structure and groups of three (catch me doing it here too). It's good writing. (Also varied sentence length.) AI trained on good writing uses the outward structure of good writing.
