rappatic··on Investor-owned utilities charge 23% more for electricity than public providers
Sure, because you’re also paying for public utilities in other ways (taxes, inflation, regulations, etc). The government can’t give you anything it hasn’t first taken from you in one way or another.

rappatic··on Breaking Claude Code Opus 5 Auto Mode
I have taught Python to high schoolers before and this is frustratingly common. Students will name their files `string.py` or similar and get crashes with esoteric error messages. It's a difficult stumbling block for someone who's just learning the basics
rappatic··on I trained a small transformer in 1.5hrs and it beats many LLMs
I don’t have any kind of ML background but I have always thought of sample efficiency as the great unsolved problem of AI. We humans have unbelievably good sample efficiency; often we can durably learn something on just a single example or two. This is the main area in which LLMs are vastly, vastly behind us.

rappatic··on Aphantasia Beginner's Guide
I agree. The afterimage test was a major red flag for me. To see something in your “mind’s eye” has nothing to do with physical vision, yet the afterimage works by exhausting some of the eye’s physical cones. It’s a confusing non sequitur and totally unrelated to the subject at hand. I have always suspected that people with “aphantasia” simply misunderstand the idea of a “mind’s eye,” believing that others can somehow superimpose something onto their actual field of vision at will. Of course, this is not possible.

Edit: it’s also telling that this website sells an “Aphantasia Membership” for a monthly fee.

In which direction are you supposed to read these charts? The arrows seem to point from conclusion/solution to reasoning, but the reasoning is at the top which makes me feel like I should read it first. It would be less confusing for there to be a single convention (eg “reasoning/evidence at the top with arrows flowing mostly down towards the conclusion”).

Similarly, I was confused by the use of both active and passive: eg sometimes “creates” and sometimes “created by,” with different arrow directions for each.

You’re talking about Amazon’s actual customers here. Is Amazon supposed to ignore the opinion of their customers for the opinion of some commenter on HN?

rappatic··on British runner Josh Kerr breaks world record for mile which stood for 27 years
East African dominance over track events has largely ended. The 1500m world record is held by a West African, while the mile and 3000m world records are now held by white Europeans. The 5000m at the recent World Championships had no East African medalists, and the 10000m had just one. Same goes for the most recent Olympic 5000m.

Compare this with the Olympic and World Championship podiums for the 2000s and 2010s; I don't believe a non-East-African-born athlete won a single 5000/10000m medal for 20 years straight.

rappatic··on Ask HN: Add flag for AI-generated articles
The quality of HN articles has degraded rapidly in the last year. It seems a meaningful fraction of articles posted here, especially most blog posts, are now AI generated. (Of course, this is the case for the rest of the internet too, but HN has always been a haven from the rest of the internet.)

rappatic··on EU commissioners shut down air conditioning for employees, leave theirs on
I feel rather silly, all the news about the heat deaths in Paris must’ve crossed wires in my brain. But it seems the two cities have similar temperature extremes, so my point is the same
rappatic··on EU commissioners shut down air conditioning for employees, leave theirs on
> but if you get a really cold spell and it drops to -35C

Temperatures near 40C have been recorded in Paris dozens of times since the early 2000s. I don't think the winter temperature in Paris has ever dropped much below -20C, let alone -35C. So this isn't a very fair analogy.

It's like satire. What is AC for if not extreme heat?

rappatic··on Newton's law of gravity passes its biggest test
When I see dark matter in the news I'm always reminded of the story of Vulcan.

In the 1800s, detailed observations of the planet Mercury showed that its orbit was slightly different than Newtonian mechanics predicted-- a difference of about 43 arcseconds per century. The study was rigorous enough to rule out any observation errors.

Le Verrier, the astronomer who made these observations, wondered how to explain the difference. A decade earlier, he had noticed a similar irregularity in the orbit of Uranus, which led to the discovery of Neptune, whose gravity caused these perturbations. So Le Verrier reasoned that something similar must be going on for Mercury, and he posited the existence of Vulcan, a tiny planet close to the Sun.

Many attempts were made for decades to observe Vulcan. It was even included on some maps of the Solar System at the time (https://www.loc.gov/resource/g3180.ct003790). But it was never conclusively observed.

When Einstein published his theory of relativity in 1915, the mystery of Mercury's orbit was finally explained-- Newtonian mechanics were simply incomplete, and the irregularity of Mercury's orbit was due to relativistic effects.

Could it be that something similar is happening today? Observations of gravity on galactic scales doesn't quite align with what relativity would predict, so we use dark matter to fill the gaps. We've tried for decades to detect dark matter, with no dice. Is our theory of gravity simply incomplete?

MOND may not be the solution, but I'm still skeptical about dark matter.

Oleophobic coating is standard on phones and tablets, which is part of why they don’t pick up fingerprints as easily.

Some brands offer coating you can DIY yourself (eg ProofTech OLEOPEL) but these seem mostly designed for phone screens. I don’t know whether they’d be as effective on laptop screens

rappatic··on How and why to take a logarithm of an image [video]
Similarly, it's possible to take the derivative of a song. You can use a Fourier transform to express the song's waveform as a series of sin and cosine functions, then take the derivative.

Imagine, for the sake of simplicity, you could express the song's waveform with the function 13 * sin(41x).

The derivative of this function is 533 * cos(41x).

Cosine, of course, is just a phase shifted sine, and the constant coefficient inside the function stays the same. So you're not changing anything about the shape of the wave, just stretching it vertically.

This has the effect of mimicking a "high pass filter," amplifying the volume of the highs.
