fat_cantor··on Turns are Better than Radians (2022)
> The natural logarithm being its own derivative

the derivative of ln(x) is 1/x

> the derivative a radians-based sin(x) being cos(x) and so on. Make it any other unit, and you have a mess of conversion factors worse than 2pi.

the derivative (with respect to x) of sin(x) is cos(x), regardless of units for x. Otherwise the chain rule wouldn't work

fat_cantor··on Google DeepMind Paper Argues LLMs Will Never Be Conscious
That's what the paper's abstract says:

>Crucially, this argument does not rely on biological exclusivity. If an artificial system were ever conscious, it would be because of its specific physical constitution, never its syntactic architecture.

fat_cantor··on Map To Poster – Create Art of your favourite city
If you just type "Salem" for the city, it just picks one and goes with it. If you type "Salem, Oregon" vs "Salem, MA", it gives the desired result (at least for the cases I've tried), and then uses your input text as the caption.
fat_cantor··on Dollar-stores overcharge customers while promising low prices
I noticed my local wal mart doing this, not on every product, but more than one. I had hoped it was an honest mistake until it happened on my next visit. I told an associate about it, left my groceries, and I haven't been back. It's wild to think that a few decades ago they accepted returns of any product based on trust, no questions asked, regardless of whether you had a receipt.
fat_cantor··on Greeting Vocalizations in Domestic Cats Are More Frequent with Male Caregivers
A lazy error [0] in the abstract suggests that the paper may have been written by a domestic cat (Felis catus). Given that male experimenters tend to stress out mice [1], it is plausible that the opposite effect occurs in cats. Mostly, it would be fun to know whether cat greetings reflect different motivational or emotional states, since reasonable people might believe that they don't.

[0] "We also tested whether demographic factors such as the influenced the amount of greeting behavior expressed by household cats."

fat_cantor··on How the cochlea computes (2024)
It's a graduate student writing a journal club article about the Lewicki 2002 paper, which is very good, and whose abstract states the idea more precisely: "The form of the code depends on sound class, resembling a Fourier transformation when optimized for animal vocalizations and a wavelet transformation when optimized for non-biological environmental sounds"

fat_cantor··on What is the most realistic submarine movie? (2019)
Adm Greenert nicely describes the attitude toward early 90s sub movies (Hunt for Red October vs Crimson Tide). For this audience, in addition to driving maneuvers, he might have added that the main premise of Red October (a clipped message) never could have happened under the existing communication protocol.

fat_cantor··on Tell HN: Y Combinator backing AI company to abuse factory workers
Yet this is exactly how educational curricula are being developed right now - AI generates lesson plan based upon standards (easier for teachers), teacher feeds in reading assignment, etc., AI generates quiz and grades responses. Maybe there's human oversight, maybe not, but the education industry is largely embracing this AI control layer without much hesitation because it reduces cortisol for everyone except students.

fat_cantor··on In Defense of Y'All
Never heard anyone pronounce the v in that one, it's always Y'all'd'a, as distinguished from y'all'odda (you all ought to). Similarly we have y'ontu? (do you want to?). Jeff Foxworthy has a bunch of these examples

fat_cantor··on Ask HN: Can calculus be taught without differentiating or integrating by hand?
At my university this was called 'business calculus'. It's enough to get you through most of economics and finance, but not enough to understand basic physics. You can memorize crap about pendulums, but you won't understand Newton's theory of gravity in the end, and you'll be even more lost on the fancier stuff like Maxwell's equations. Sure, you don't need that level of understanding for most computer stuff, but I frequently find that it helps.
fat_cantor··on Food ingredients changed over 150 years
It's an American thing, which traces to Bill Clinton's development of the factory farming industry when he was governor of Arkansas. The good old-fashioned eggs and chickens are still widely available at farmers markets, etc., but presumably not used for testing here. The point about cayenne being the only chile-based heat also depends on region - Cajuns, Creoles and New Mexicans would likely disagree. Edit: another factor is probably the dramatic decrease in the population of insects since 1970, which affects the composition of both the chicken and the egg
fat_cantor··on Press Conference: Professor Geoffrey Hinton, Nobel Prize in Physics 2024 [video]
dang thanks for the url change. The detail I would not otherwise have noticed was his rejection of the idea that AI might dumb people down (~13:00). He states in analogy, unironically, that you don't need to be able to do multiplication tables if you've got a pocket calculator. However, as we've recently discussed, but perhaps not enough, learning your multiplication tables isn't optional if you want to understand math. It's part of the language.

fat_cantor··on Nobel Prize in Physics awarded to John Hopfield and Geoffrey Hinton [pdf]
A Hopfield network is a lot more like physics than biology, but agreed that the conformal field theorists should have been recognized before Hopfield and/or Hinton. Jim Simons would have been deserving too, IMHO, far more for his work at RenTec than for Chern-Simons theory

fat_cantor··on AI agent promotes itself to sysadmin, trashes boot sequence
*Fortunately* (for manual street navigators), people who only use GPS think the art of manual street navigation is impossibly complex. During heavy traffic, we can use maps to find out where those people are being herded, and manually navigate even more efficiently. Also: it's nice to know if there's an accident somewhere.

fat_cantor··on Cox slows Internet speeds in entire neighborhoods to punish any heavy users (2020)
A year ago, I had fast Cox internet for $70 per month. I moved a mile away, and Cox wanted at least $233 for any connection at any speed because AT&T was not a competitor in that neighborhood. I said no and relied on 5G until AT&T moved in a few months later with the $70 market rate. When business people take control of companies from engineers, we get enshittification. Cox has somehow managed to make me nostalgic for the enshittification phase, which has morphed into this logjammin phase where no one even pretends to be competent enough to fix the cable.
