"Keplerian" is a term of art based on the rotation curve in Newtonian gravity when all the mass of a system is concentrated at its center. For the Solar System, the rotation curve outside the radius of the Sun is pretty much pure Keplerian: the velocity decreases proportional to the square root of the radius.

For galaxies, which are extended objects, the rotation curve is not Keplerian when you are well inside the galaxy: it first rises to larger radii, then levels off. But since the baryonic matter (stars, gas, dust) in galaxy is rather centrally concentrated, the rotation curve should start looking more and more Keplerian as you get further and further into the outskirts and outside the galaxy.

But that is not what we see. Instead, we see the rotation curves staying roughly constant with radius ("flat"); we call this "non-Keplerian". This is true for almost all galaxies, including ellipticals and lenticulars (this is a recent study of three lenticular galaxies: https://www.aanda.org/articles/aa/full_html/2020/09/aa38184-.... Note the rotation curves in the bottom panels of Figure 3: they do not at any point start decaying, let alone decaying as fast as R^(-1/2).)

Figure 5 of that paper (https://www.aanda.org/articles/aa/full_html/2020/09/aa38184-...) shows the observed rotation curves; it also shows the predicted curves if just the stars and standard Newtonian gravity were operating, with the dotted red lines. Note how these lines first rise to a local peak at small radii, and then decline to larger radii: this is a (quasi-)Keplerian decline. It fails to match the actual rotation curve at large radii.

The conventional response is to postulate some additional form of matter, distributed in a much more extended fashion than the baryonic matter (this produces the dashed black lines in Figure 5 of that paper). The MOND response is to modify gravity (or: to modify the acceleration due to gravity) such that it doesn't show anything like a Keplerian falloff at large radii, even at radii where the gravitating matter (assumed to be just the visible baryonic matter) is well inside.

In the case of the Solar System, the Keplerian decline starts right outside the Sun, where the acceleration is strong enough to be above the MOND threshold. But if you went far enough out and could measure the circular orbital speed, MOND would start to deviate from Keplerian. In the case of galaxies, the outer radii where the rotation curves appear "flat" are where the acceleration due to gravity is low enough for MOND to matter, and so the predicted MOND curves will not be Keplerian.

(I should perhaps point out that I'm a professional astronomer whose been studying galaxies, including lenticulars and ellipticals, for almost 30 years, so attempts to mansplain my field to me won't really impress me.)
Hah, just yesterday I had a conversation where an individual told me that I have no pride in my work if I don't devote 100% attention to it and I guess today's generation has no shame. I politely pointed out that I work based on results requested. If someone wants different results, they should adjust accordingly.

But no.. you want 110% and everyone looking busy, because.. manamagement does not know how to manage..

No offense, but to me it shows severe lack of skill in management class.
Editorialized a bit to have a clear title.
"Perfectly synchronized?" I airplay to 6 sonos speakers using airplay2 (not grouping in the app) multiple times a day, and I can practically predict what will happen if I try to add speakers too quickly, or too slowly. You'll add 2, then a 3rd, then you'll notice one isn't actually playing, and when you add the 4th, all the rest drop out, and you get to re-add them again. It's such a chore to keep a multi-speaker airplay setup working right.

A lot of this could be solved if Apple put some basic engineering effort into the airplay UI, such as adding aliased groups. Every time I want to play to my effing speakers it's a 60 second ordeal.

Sometimes the little banner pops up from the top of the screen helpfully letting me to play to all of the speakers like I was before. Other times it not-so-helpfully suggests just playing to ONE speaker for some incomprehensible reason.

Still other times, the banner covers what I'm trying to see, and swiping it away seems to activate airplay even when I don't want to.
You're keeping us in suspense. Did he ever manage to kill the System Idle process?
Person of color is not for "non-white", see: east asians.
It is extremely silly and in bad faith to accuse anyone to disagree with of indoctrination, but it's even sillier when every single tech bro is basically the same person, reads the same books, repeats the same topics, on the same day using the same phraseology.

You could have literally taken this essay from PG posted it on the timeline of any single one of his colleagues and you couldn't even tell who wrote it. The "anti woke" economy, if you look at the numbers accounts of that flavor do on Youtube, Twitter et al. is a magnitude if not larger than what, according to them, cannot be criticized.

The phrase "woke mind virus" also featured in this essay, is more of a literal meme or mind virus in the Dawkins sense of that term than anything it attempts to address. The lack of awareness to accuse others of indoctrination when you write an essay so generic that you can autocomplete the last 90% after reading the first 10% chatgpt style is quite something.
I feel like Work from Home would be a great solution to the housing crisis, as it would allow people to easily live in affordable areas. A tax break or something for businesses which implement WfH would be a good starting point for this.
Not a mental breakdown, but, a memento mori for all of us:

The problem with success is even when success is a reality, it's effects are temporary.

You get hungry even though you have just eaten.

The most telling moment for understanding what's going was Matt responding to successful critics by saying they weren't successful enough

I can't remember exactly what he said, & too much has happened for me to find it with 5 minutes of Googling. Something like "oh yeah well you only got to $2B valuation and it took 1000 engineers, what do you know"

If there is a breakdown here, it's one I've seen before, but wasn't cognizant of until I saw it 100x over at Google, sometimes tragically: you got everything you thought you wanted, but you're bored enough to need a new challenge, but you're not cognizant enough of it to effectively make that choice _before_ your actions show you that you need to.

Doesn't help any that it would amount to "backing down" in this scenario, he can't say that now without people thinking he was forced out somehow.

When I think about this, I also remember:

- the somewhat odd acquisitions over the past few years, Tumblr, that one cross-platform messaging app that got a ton of press for insisting they'd do iMessage....another strong indicator of boredom with the day-to-day, IMHO.

- His clear, repeated, focus is on money. It's never in primary focus, but it's always there, in everything lashing out that is publicized. If you're unhappy, and you're not sure why, and you have everything you thought you wanted, one easy thought train to jump on is "the compensation is not commensurate for the work"
I‘m extremely happy about my 50 year old WEGA speakers that sound way better than any Homepod or Sonos that I had before. And I paid $90 for the used LB3541.
I'd point out that all that was needed to add that capability to a 1970 stereo is one of these devices:

https://www.sonos.com/en-us/shop/port

Although I laughed out loud that they're asking $450 for that little box. That's pretty cheeky. The BOM on that must be $15. Margin level: Apple!

I wonder if they make it $450 to discourage doing just what I'm describing. To make people consider that for that kind of money they could buy one decent Sonos speaker and "simplify." Even though the Sonos speaker won't have anywhere near the sound quality or longevity of a 40-year-old stereo amp and speakers.
I assumed it was part of the migration plan to Apple silicon. Rosetta 2 makes x86 apps work on Apple silicon, but I had assumed that Apple could only really get 64-bit x86 apps working smoothly and that’s why they removed 32-bit support a few years earlier.
I didn't down vote you, but I assume it's because at best, you arent saying anything that adds anything interesting, and at worst you're just being contrary. You hated playing the clarinet, so what?
What is accountability? A platform picking what the truth is?

Presumably you liked the fact checkers before because they were of the same political persuasion as you. Now that Trump is in power would you prefer if Musk/Zuckerberg placed right wing fact checkers in place and punished any opinion which is outside of the platform's Overton window?

Musk removed picking fact checkers and replaced them with community notes. Zuckerberg says he'll do the same. Isn't that the societal accountability that you want?
Could be the terrain and geology. About 15,000 years ago, after the last glacial maximum subsided, the largest flood in history carved out that part of Oregon. Maybe there is a similar timetable where the Columbia is silted up.

From Wikipedia: "The wagons were stopped at The Dalles, Oregon, by the lack of a road around Mount Hood. The wagons had to be disassembled and floated down the treacherous Columbia River and the animals herded over the rough Lolo trail to get by Mt. Hood."

That's an anecdote, no? No idea where you live (guessing New Jersey?). But do you think there might be other differences beyond just the $/student that might explain some of those differences? What're the poverty levels of those urban children vs their suburban counterparts?

> Instead of going out into the world and quietly helping members of marginalized groups, the politically correct focused on getting people in trouble for using the wrong words to talk about them.

I also think there's a pretty big difference between keyboard jockeying / speech policing, and putting yourself in physical danger by physically confronting racists who'd lynch you if there weren't cameras around.
> I mean, yes, a lot of people drop out of music because it's hard to get good at it and stay good at it. But how does Suno AI solve that problem? How does Suno make it easier for someone to learn how to express themselves through a musical instrument?

The same way DJing does? That's a form of music "creation" which involves less skill than mastering a musical instrument.
Yeah other than the minor thing of swinging an election. lol.
Show HN: ZeroEntropy (YC W25), Advanced AI Search over Complex Documents
Hey there YC!

We’re Ghita and Nicholas, the founders of ZeroEntropy.

We are on a mission to build the world’s most accurate search engine over complex and unstructured documents, behind a simple API.

If you are building RAG, a search bar, or search tools for your AI Agents, please reach out to us here founders@zeroentropy.dev

*Why*
Most AI products - whether Q&A bots or AI agents - depend on retrieval systems to provide relevant context from knowledge bases.

Yet, the vast majority of these systems rely on basic semantic or hybrid search methods, which still frequently fail.

These mistakes lead to inaccurate responses and hallucinations by LLMs, frustrating developers and end users alike.

That’s why we’re building ZeroEntropy: to add intelligence to retrieval, and empower developers to build reliable and accurate AI products!

*A few common failure modes*
The most common examples are:

- Negated Queries, like: “Which electric vehicle articles do not include any reference to Elon Musk?”.
- Multi-Hop Queries, like:“Where was the suspect who was identified in the report born?”
- Fuzzy Filtering Queries, like: “What diagnostic methods are suggested for early-stage cancer, in papers that mention a sample size of over 2000?”

These types of queries are common in industries like legal, healthcare and manufacturing, where documents are very complex. Semantic similarity and keyword-based approach fail on all these examples.

*Our Solution*
Search AI agents can solve these complex queries. Not only can they understand the user’s intent, but also route each query to the most suitable retrieval system, ensuring precise and relevant answers. Moreover, they adapt and personalize their performance over time, continuously improving with use.

All of this capability is accessible through a simple API that you can try out at: dashboard.zeroentropy.dev.

*About us*
We both have a background in math and AI: Ghita has two masters in Applied Maths from Ecole Polytechnique (Paris) and from UC Berkeley, and Nicholas grew up doing math and coding competitions at CMU before becoming the CTO of several startups.

We’ve both experienced the pain of building great retrieval systems from working as AI engineers and researchers in several industries from healthcare, to finance, to B2B SaaS, and consumer AI.

*PS/Fun Fact*
In case you’re curious about our name, in information retrieval, entropy refers to the expected variability of information contained in a variable or message. ZeroEntropy refers to knowing exactly what the message contains and is associated to a high predictability, low chaos state. In physics, absolute zero entropy is impossible to achieve. But we’ll try!
Sonos makes great hardware. Those little mini speaker voice assistant things aren’t even in the same ball park. If they stick to their target audience they’ll be fine.
Right, but animals aren't as picky as humans - they'll eat anything that isn't rotten (and then some animals actually prefer rotten stuff). Meanwhile people will avoid buying veggies that look off even if there's no risk to health or taste involved.

I suppose this is because most animals in the wild are always couple hours away from starvation and just can't afford being picky eaters.
Hey! this is exciting to see! Hi Earl and Oisin! (I've had the pleasure of meeting Earl and Oisin face to face a few times. Really friendly and smart guys, fwiw based on my convos they are very serious about building a compelling product, excited to see it on hn!)
> I think it's okay to refer to the word "woke", but if you use it more than 3 times in your writing, then it's hard to take you seriously.

But when the essay is specifically about where "wokeness" comes from and what (pg) understands it to mean, then it has to be OK to use it more than 3 times?

> Because it's a word that gets people emotional. Getting people emotional is the opposite of what you want to do when you're trying to intellectually dissect something

Some terms are so charged that it's virtually impossible to have discussions without any emotional reactions to it. "Woke" seems to be one of those subjects/terms (at least judging by this submission), so if you try to shy away from it just because of that, isn't that a disservice as a whole? We need to be able to discuss and think about hard things too, not just fun and happy stuff.

> It's just like if somebody wrote a piece about trump, but mentioned he was a felon 4+ times, you'd know they weren't writing an unemotional thinkpiece.

But the comparison here would be an article whose purpose is to detailed how Trump is a felon, then obviously it'd make sense that it gets brought up, it's the subject of the text.

Remote jobs are essentially saving people about 1 hour of travel time, per day.

Assuming a 5 day week, and an 8 hour day, thats a 10% salary bump. In practice it’s much more, since thats time you get back to spend on a variety of things, that just getting more money wont provide. Being at home, means breaks or down time help you get stuff done, and save even more time.

WFH allows for many virtuous cycles to be set up, IT moves wealth away from down town areas, and into lower cost of living regions, letting people save more money, and invigorating local commerce.

MY guess is that WFH is what society needs as a whole, wherever it can get it. Cities and municipalities should plan and compete to get the largest number of people working from home within their boundaries. Get reliable and safe mass transit up and running, and you can even cut down on short hop fuel consumption.

Money concentration is great when it helps generate more wealth for humanity at large. If it’s only going to a small group, then distributing it amongst the broader populace will (should) drive up demand, resulting in more economic activity, and therefore a stronger economy.

Heck, extend that logic to a global scale, and you’ve basically created a reflection of outsourcing. Do WFH instead.
Yes, I feel the same way. The lack of critical thinking about AI is almost shocking… and then I remember how messed up humans are and it doesn’t seem shocking, just depressing.
The first email asking to remove a single map from a sub-feature of the website is very reasonable.

> The text below the title says stage 4 GBM, that is the specific form of brain cancer. So that’s that…

Which kind of GBM? You're aware there are different kinds, right?

> So what I am asking the community is: has anyone DIYed any of the promising technology and obtained any results. Seems fairly reasonable in a life and death situation.

> As a matter of fact, someone who has GBM has indeed done just that (see in the thread). Unfortunately his experiment just started, so I can’t know if it worked for him or not yet.

And if his GBM does go into remission, you still won't know if it worked for him.

In fact, no one has "indeed done just that". No one has obtained any results.

> I don’t understand why people can’t stomach the Zika idea. A ton of medical research involves infecting people with live viruses.

I can stomach infecting people with live viruses just fine.

What I can't stomach, is someone saying shit like: "Meanwhile, it is proven that the Zika virus does kill GBM cells in humans. This is what causes microcephaly in newborns. Inoculating the Zika virus in a controlled environment yields zero risk, and has no side effects."

Uh, that's not proven, and "zero risk" and "no side effects" is not a thing in medicine. I'm not aware of any treatment for anything that has "zero risk" and "no side effects", let alone some bleeding edge treatment with a virus that has barely been studied as an infection let alone as a treatment cancers. Even the studies you linked did not say what you claim here: that's you literally making shit up. You said that, it's a quote of you, and it was dangerously incorrect.

I think it's a pretty reasonable rule of thumb that if someone says someothing has "zero risks" and "no side effects", they should be ostracized from medical conversations. You simply do not know what you are talking about and should stop talking about it, because what you are saying endangers anyone who believes you.

And as I've reiterated a few times now: you do not have cancer, so whatever harebrained grasping at straws you would do if you had cancer is irrelevant. Your friend is the one with cancer, so maybe ask them what they want before inundating them with your irresponsible, unqualified medical advice.

I am sorry about your friend, I really am. But that's not an excuse for you to spread medical misinformation.
Society, in its grand equality, gives rich and poor alike the ability to spend their money on billboards and full page ads.

try
call remote_startserver('VIM-' . getpid())
catch '^Vim\%((\a\+)\)\=:E\%(941\|240\)'

I agree. Wokeness has a very precise meaning: World is divided between oppressors and oppressed. Oppressors are white heterosexual men (white supremacy / heteropatriarchy) everyone else subjugated to them. Institutions, laws are created to perpetuate that power and must be dismantled / subverted via revolution.

Most understand it even if they can’t articulate a definition. Easy to point out when a movie or corporate initiative, behavior is woke.

As a minority in the US, I experienced little to no overt racism from 2014 to the present, following years of derogatory comments and unsolicited "jokes" about my ethnicity from people who weren't fundamentally racist but still thought it was OK to say those things. I attribute this change directly to the rise of wokeness (read: awareness) around 2015 and thus have a soft spot in my heart for it, even if some of its excesses over the years have made me roll my eyes.
The terms are being diluted hard. Everyone from a plumber with a no-code RAG automation tool to a FAANG phd can and have claimed the role “AI engineer”, and it can be true depending on the context.
