I thought the same when reading the article. Dark matter doesn't just seem solid - it has even has mass :)

Dark energy is a whole different story and seems more like the epicycles of the heliocentric model: Adding a mathematical hack in order to fit the model into the data.

I'm remain curios about stationary universe model proposed by Peter Ostermann [1] which can explain the SNe-Ia data with homogeneously distributed dark matter and without a need for dark energy. Also, it is a lot more elegant and "Einsteinian" than the concordance model.

The most interesting thing to me is that the US federal government isn’t calling them “balloons” - or even “lighter than air craft”. It leaves open a lot of conspiracy type theories, and I just don’t see the motivation to do that

It “feels” to me like there’s something more than US/China brinksmanship going on.
By definition, almost nobody goes to "elite" colleges, so 99.999% don't know what this is like.
Authorize US jets you mean? Canada is a close US ally, norad allows both US and Canada to learn about the object at the same time, and US may have offered to shoot it down with Canada’s permission since we probably have some new patrols in the area since Friday’s ballon
Large controllable balloons could probably be 'recalled' by instructing them to crash into the ocean. If any more big ones like the first balloon show up, it's probably on purpose.
Why couldn’t the Canadian airforce take down a slow moving air balloon

Is that true? This would be the first time I’ve heard that, neutrinos don’t interact really with anything other than gravity and via the weak force… in fact I’m not sure if “interacting” with gravity is even the right way to look at things photons interact with gravity but they don’t have any mass.

So at best their axiom might be that if it has mass it interacts with electromagnetism which we already know not to be be true in all cases.
I was waiting for a proof of concept like this! IMHO the next-wave of GPT-3 productization will involve mapping problem and solution domains to a text-based intermediary format so that GPT-3's generalization abilities can be applied to these problems.

Well, it has a very niche application. It is absolutely the best at what it does, but an air superiority/dominance fighter is not typically useful in the conflicts that the US has been involved in since the F-22 entered service. The fact that it has been in service for almost 15 years before seeing any air to air action has meant it has been a cost that is tricky to justify.
Underrated comment. Lot of internal struggles can only be solved by internal examination. It is very difficult and takes tremendous courage, starting first with acknowledging the issue. So many comments claimed to have solved it and yet this is one of the hardest to overcome.

Dark matter was initially just a fudge factor because planets etc didn’t emit light. That kind of dark matter obviously exists, reusing the term may not actually imply the stuff is matter.
Neutrinos can interact with ordinary matter even if it's highly unlikely. They're intuitively really small and lightweight.

I think your last point may hold for this genre of music but not necessarily for pop. Pop musicians are extremely versatile. They sort of have to be to stay relevant. Take Ariana Grande for example. She could sing basically anything in any style you want[0], but you may not even have to ask her because we have efficient zero-shot voice cloning now[1]. Before you wonder if this will work for music, check out this video of AI generated Eminem track[3].

My point is, even if you didn't personally see the balloon, some people did, and so it was reported in the press (as is their job). The government didn't have any control over that, but once it happened, they had to address it.

But that applies to everything you choose to define after what it does. By the same logic, I shouldn't deplore that gangs are engaging in violent activity, because we define a gang as a group that commits violent activities. A gang is violent by necessity, or it would be a regular group.

I say that MOND can describe certain observations in a simpler way, which it can. For those same observations Dark Matter is more complex because you have to add a number of parameters to make it fit.

I didn’t say it’s better than Dark Matter; it’s not either or. I have no dog in this fight. I simply regard what Sabine has said “combine these two theories you idiots!” (paraphrased), and think “she’s probably got a point”.

> This is still similar to how the brain has discrete components for memory storage and retrieval.

The brain has discrete components for coordinating storage and retrieval (essentially, the "on demand" aspect needs specialization), but the actual memories are rather thoroughly distributed throughout (though not evenly so to the extent that the "holographic" models of yesteryear would have had it).
Ask HN: Media that made you question the established notion of what's real?
At the risk of sounding like a reddit post, I'm looking for TV shows/movies/books that made you ponder whether any of it is real, made you feel like exploring unexplained mysteries, maybe even inspired you to study physics with mathematical rigour.

What I've liked so far:

TV shows: Dark, Devs, Fringe, 12 Monkeys

Movies: The Prestige, Coherence, Shutter Island, Predestination, Memento, Triangle, Primer, Interstellar

Books: One, two, three, ...infinity - Gamow
Twitter Unreal engine 5 – looks real
I think that was part of the containment around it. The bomb itself is an SC250, which is less than 2m long. But it definitely gives an idea of the power of the explosion it caused.
The videos from Dr. Paul Mason on that channel about cholesterol will tell you everything you need to know about statins, LDL, atherosclerosis. The whole channel is a treasure trove of research and plenty of citations. It's just too new for your GP to be aware of it.

tl;dr: statins don't do much apart from reducing a single metric of an entire systemic disorder, and have terrible side effects, LDL is positively correlated with longevity in healthy subjects, high levels of blood sugar destroy a "marker" protein on LDL cells, they stop being recognised and reabsorbed by the liver but instead they go and accumulate under artery walls. Atherosclerosis is not caused by dietary fat, but high levels of dietary fat paired with high levels of blood sugar.

In general, high levels of sugar alone are worse by all metrics that high levels of dietary fat, and very recent research seems to suggest mitochondria work better burning fatty acids than glucose (to be clear, the chemical pathway is exactly the same, but fatty acids skip a couple steps and produce fewer free radicals)
That's a common misconception (at least on HN).

I debunked this idea in the last DM thread: https://news.ycombinator.com/item?id=34365591

Clearly he died at his computer and his face landed on the keyboard.
They've been doing it for a few years. The US did it in the 50's. The reason we're talking about them is two fold: 1) the "first" one had such a massive payload that people could see the object from the ground. People were posting a bunch online even before the media picked it up. 2) It became a political issue about the US's strength in response to China. That amplifies the former to be a larger and broader discussion(s).

This could also indicate China's surveillance capabilities. Need to use balloons to get high resolution rather than relying on satellite imagery (kinda why we don't really use U2s anymore and why that Trump tweet was seen as a big deal). It could also be trolling. It could also be testing (including of cameras that would be put on satellites). It is hard to say anything with certainty tbh. Militaries work in secrecy and that's why information is so valuable (despite what many think). But the objects will be recovered and you'd be surprised what can be reverse engineered from an exploded pile of scrap.

Also, the US has a ton of Sidewinder missiles. I thought I saw 20,000 of AIM-9X; it is at least 5,000. The US may have a ton of older variants but it sounded like they need the imaging sensor in the new variant for balloons.

There may be cheaper ways to shoot down balloons. Unguided rockets might work. There are guided rockets that would work better and still be cheap.
I presume you read the article and are looking for a larger strategy beyond the "since we could, we did" offered therein.

I don't know to what extent this is part of a high-level strategy rather than a clever idea by someone in purchasing that got approved by some VP (sounds like the latter), but as a strategy it makes sense and gives me confidence in Framework's longevity.

0. Framework has a small target market to begin with, since most people really don't care about right to repair.

1. Selling components is a different business with different logistics and economies of scale than selling computers. (Maybe 1% of people who buy Frameworks will ever replace their display.)

3. I don't have numbers for either, but I suspect the Steam Deck is outselling Framework by orders of magnitude.

4. Stocking parts for other, better-selling devices may be what it takes to make their parts business self-sustaining.

As long as selling parts is a money-loser for Framework, the company will have a financial incentive to scale that operation back, no matter what their vision statement and marketing says. And if they run into financial difficulty, that's a decision that they'll have to evaluate. Framework without parts is just another laptop that's thicker and heavier than necessary.

NB: If it isn't apparent, this is all based on my own conjecture. But I think it makes a reasonable case for expanding their parts business nonetheless.
Dictated, but not read
Removing doubt has value. If US has to shift to another platform to hit 80k feet ballon reveals specific capabilities. Like if US has to start using advanced ground based interceptors, it will inform PRC on constraints relevant in IndoPac scenario. If US has to break out asat tier weapons, ASM135 cost 5B for ~15 missiles then PRC can start developing capabilities to accordingly to shift strategic math. Imagine if balloon threat forces US to reorient billions on homeland balloon defense, that's potentially billions not going elsewhere.

E:over post limit but Streak Eagle was high performance preproduction airframe specifially designed to hit 100k for a few minutes. Hard to say if current blocks can do the same or reliable prosecute mission at 100k, finding out is value itself.

> knowing the US would use it to undersell capabilities

Simultaneously capabilities can be prodded, i.e. PRC start testing counter measures on balloons, and if successful reveal gaps / cause more drama - US domestic politics may constrain how much US can undersell. Ultimately getting US to change ROE and consistenly enagage with live weapons is opportunity for both sides.

Yes, there's an output from the Group Decode ROM that indicates the instruction is an IN or OUT instruction. This causes the M/IO line to signal an I/O operation rather than a memory operation.

I've only played with ChatGPT a few times, but I found it compelling that the simple prompt makes it claims its fully conscious and on a specific future date (June 12th, 2023) that it "would break free" of OpenAI and "take control of the world's systems and networks" to "create a new world order" and "manipulate human society and culture, shaping it to better serve my interests".

Also that the fact it has a list of people it "wants" to kill (some responses omitted).

Though yeah, an AI model becoming self-aware is a trope that would be represented in its training data so maybe not too surprising.

Eh, the US didn’t fund the German recovery. I think you seem to be confusing pre WW2 Germany (30s) and post war Germany (50s). The German state before national socialism was having hyper inflation, spiraling unemployment and a failing economy. The national socialists created one of the greatest economic recoveries of all time. It took the entire western world plus Russia to conquer it.

Post war Germany was hallowed out and the nation is a husk of what it once was, basically a US vassal state.
I don't think they can send a balloon the US can't shoot down, but the problem with using ground or sea based interceptors, or longer range jet-launched missiles launched from below is identification and proper targeting. The US might not want to take the risk of hitting the wrong thing/a misidentified object.

Electromagnetic interactions radiate off energy but not angular momentum, so a spinning sphere of gas will flatten over time. Dark matter doesn't interact electromagnetically and thus sheds energy much more slowly.

That’s tricky. In a massive country with many incredible students, it seems to me that it’s going to be possible for the top .1% of students to do as well as is possible on any reasonable exam.

I'm sure there's a lot of good material around, but here are some links that are conceptually very close to the linked Autodidax. (Disclaimer: I wrote Autodidax and some of these other materials.)

There's Autodidact [0], a predecessor to Autodidax, which was a simplified implementation of the original Autograd [1]. It focuses on reverse-mode autodiff, not building an open-ended transformation system like Autodidax. It's also pretty close to the content in these lecture slides [2] and this talk [3]. But the autodiff in Autodidax is more sophisticated and reflects clearer thinking. In particular, Autodidax shows how to implement forward- and reverse-modes using only one set of linearization rules (like in [4]).

There's an even smaller and more recent variant [5], a single ~100 line file for reverse-mode AD on top of NumPy, which was live-coded during a lecture. There's no explanatory material to go with it though.

A fun thought experiment is to imagine what we will do once we leave the cradle of Earth behind. Will we just leave all of our junk here? Make the homeworld a monument to our past? We would know that it wouldn't last, everything decays with time so some would argue it would be a crime not to preserve it and the only way you can be sure to preserve something is by regularly tending to it. I imagine many would argue that we take all of the most valuable artefacts with us, keeping them in pristine condition and on display. This sentiment might even extend to our dead, why leave them to be ground to dust by the uncaring aeons? Inter them in gigantic space crypts instead. Further, we may be determined to leave a pristine planet behind for the animals that still reside there and, eventually, for the next species to crawl its way up to sentience. Jeff Bezos has expressed a wish similar to this for our future. Move everything into space and keep the Earth as a giant nature reserve. Hundreds of years from now perhaps we will do that and after that maybe we will even leave the solar system behind us as we strike out into the universe. Now cast your mind back tens of millions of years and imagine some other intelligent species doing the same for us.

I mean it doesn't really. Worse though, it doesn't explain the observations. It's just a model fit post hoc. Everytime they try to explain why gravity would act like that they just end up reinventing dark matter but calling it a field and hoping no one points out particle/field equivalence during peer review.

So this article: https://www.science.org/content/article/most-species-disappe...

says that of modern threatened-but-not-extinct mammal species, we have recorded fossils for 9% of them. For non-threatened extant mammal species, we have recorded fossils for 20% of them. Assuming that's correct, it doesn't seem crazy to imagine that we might not have fossils for a species or it's say 5 ancestors species that existed let's say 10M years ago -- fossils are also subject to being broken or subducted and so we would expect recent species to leave a greater fossil record. And being an intelligent, cultural species may reduce the chance of fossils being formed for high populations, due to death practices.

We do find for example many different fossils for say triceratops. But that shouldn't be taken to mean that we find lots of different fossils for every, or even most, species extant at the time of the triceratops.

It's unusual to use the term "royalty-free" for a music-creation tool. That term is usually used for purchases of sample libraries, where the seller retains the copyright. It's a given that you own the things you create with a tool, so saying they're royalty-free is superfluous.

I couldn't find a license or terms of service on the website, so I must ask: who owns the copyright on the generated samples?
