The official HN front page is already pretty good on UI density, so it’s promising that you’re using that as a starting point.

Is there any chance https://hcker.news is related to https://hckrnews.com? The dense layout feels similar.

I was wondering if that missing period was intentional…

So maybe it makes sense that LLMs do okay at programming even though they lack the ability to reason?

Does anyone know how Florida’s Miami–Orlando Brightline is doing? I believe that’s the only higher-speed rail route opened since Acela.

The Pale Blue Dot is an incredible image but actually understates our cosmic insignificance. Voyager 1 hadn’t left the Solar System at the time and is still light years from our nearest stellar neighbors. Even our farthest stellar neighbors—the individual stars that form constellations in our night sky—are situated in just one section of the Orion arm of the Milky Way. And the Milky Way is, of course, just one galaxy among hundreds of billions.

What exactly is the “sunbeam” in the Pale Blue Dot? Is it a real astronomical phenomenon or an imaging artifact?

I recognize Terman from the names of places at Stanford but never knew he played such a big role in the early days of Silicon Valley.

Isn’t OP analyzing frequencies of individual chords, not chord progressions?

Analyzing individual chords involves counting the frequency of each chord (such as G, C, or D).

Analyzing chord progressions would involve counting the frequency of chord pairs (such as D—A or C—G), chord triplets (such as D—A—Bm or C—G—Am), or longer sequences of chords. For an alternative look at the data, you could also normalize chord progressions across key signatures for your analysis (D—A or C—G would both normalize as I—V, D—A—Bm or C—G—Am would both normalize as I—V—vi).

That’s an anime that should be made.

I prefer the dedicated minus (U+2212) over the hyphen-minus (U+002d) for mathematical use because they look different in most font faces.

Are there cases where the dedicated hyphen (U+2010) is preferred over the hyphen-minus?

So either our understanding of nucleosynthesis is incomplete or the universe is older than we think.

Which one is more likely? Are there assumptions or parameters in our model for the age of the universe that could be inaccurate?

A closely related follow-up blog post could be titled: “How Long Twilight Lasts”.

I think they have all been trying [1][2][3] which is why assessments about voice assistants from 2019 might not apply today.

2019 was before ChatGPT. Generative AI could change the game for digital voice assistants.

Where can I get the meter-long slide rule the man is holding in OP?

One type of gravity waves can be seen on Earth where its atmosphere meets large bodies of water. These are commonly known as ocean waves.

dang, would you be able to update the title for this thread? The full title is too long for HN but could be shortened to: “Bispecific antibodies potently neutralize SARS-CoV-2 variants of concern”.

This is a good explanation of chirality but I think the parent meant to say enantiomer instead of racemate:

– enantiomer refers to each mirror image of the molecule. https://en.wikipedia.org/wiki/Enantiomer

– racemate refers to a 50-50 mix of the two enantiomers. https://en.wikipedia.org/wiki/Racemic_mixture

The hardware components have become so small that there is no longer a need to design a creative enclosure. All-in-one computers—phone, tablet, or desktop—can now approach the Platonic ideal of that single flat screen.

What happens if it’s the middle of winter and the grass is completely covered with snow?

> Many who advocate for cutting NIH’s indirect cost rate have long argued that universities are willing to accept lower rates from philanthropic foundations. Today’s NIH notice, for example, notes the Gates Foundation limits indirect costs to 10%, while the Packard Foundation sets the ceiling at 15%. But such reasoning is based on “perverse logic,” Corey says, because foundations use their funds to increase the productivity of research infrastructure already paid for by the federal government. And universities say they are often willing to accept foundation grants that carry low overhead rates because those grants amount to a relatively small fraction of their funding.

This detail is worth highlighting. NIH has traditionally borne the bulk of indirect costs, allowing non-profits to issue grants with low indirect costs. Slashing NIH’s indirect costs will force research institutions to seek funds elsewhere or become financially unviable.

> Did it again in the midst of winter, and the staff allowed me and the two other blokes to stay for the night in the next departing train with the heating on.

That’s a notably kind and humane gesture in the midst of winter.

Zen and the Art of Motorcycle Maintenance describes how motorcycle maintenance by the owner is qualitatively different from motorcycle maintenance by a professional mechanic. The professional mechanic can examine the motorcycle at a single point in time, but the owner rides the motorcycle and can collect observations as the motorcycle runs.

Understanding your body can be similar. While medical expertise is absolutely worth consulting, doctors can only base their diagnoses on your self-reported symptoms and on their examinations at single points in time. The more data you collect and report to the doctor, the more likely you can work out exactly what's going on.

I know someone who lived with chronic discomfort, observed over several years, and after many doctor visits finally pinpointed the root cause. Best wishes to the author on his search.

I always thought that comets come from the Oort cloud, but apparently short-period comets come from the Kuiper belt or its associated scattered disk—similar to the exocometary belts in these images.

I was wondering if this might be the case, similar to how Bing’s initial training included Google’s search results [1]. I’d be curious to see more details of OpenAI’s evidence.

It is, of course, quite ironic for OpenAI to indiscriminately scrape the entire web and then complain about being scraped themselves.

> The algorithm must work at least for integers in the range 1-1000. We do not care for numbers outside that range.

In that case, a list of 1000 strings should work just fine. Fast lookup and can accommodate any new rule that comes in.
