From the preprint link at the top's page 6, after Eqn (23): "While this study demonstrates that galactic rotation curves can undergo modification due to stochastic fluctuations, a phenomenon attributed to dark matter, it is important to acknowledge the existence of separate, independent evidence supporting ΛCDM. In particular, in the CMB power spectrum, in gravitational lensing, in the necessity of dark matter for structure formation, and in a varied collection of other methods used to estimate the mass in galaxies.
These now form an important set of tools with which to test [our] theory".

Other lines of evidence like the one at your link just increase the ability to test their theory (which is meant to solve some quantum gravity problems at very small length scales) at very large length scales.

They are not motivated by the desire to prove MOND is correct or that cold dark matter doesn't exist. Rather they can show that in certain restricted circumstances their theory allows for nearly-MOND-like orbits. So their theory survives a small but important hurdle imposed by our observations of nature (we observe MOND-like orbits).

Elsewhere in the comments someone asked the good question of (highly paraphrasing) whether this success is wiped out if a distribution of dark matter is added to their SdS-like universe as the generator of some of the observations normally taken as proof of \Lambda-CDM. That question is closely related to the final sentence in the quote above, and answers are hard to guess at.
Every single major OS ships with a simple screen recorder. Name your OS and I'll tell you the name of the screen recorder you already have installed right now.
The value equivalent of that was invested into computation technology long before even a half-MIPS machine was produced. Its funders had the foresight to look beyond the present day.
Telecom legacy, probably. The ONT is seen more like the old "demarc" / "network interface device" from the copper days. You didn't install your own demarc: that was done by the telephone company. Everything after the "demarc" is customer operated, everything before the "demarc" is telco operated.

Operationally, it also simplifies things having a relatively uniform set of ONTs. With cable modems, there are 100's (1000's?) of models that have to be evaluated, tested, certified. Cable companies often do their own firmware updates.
I was under assumption that, to reach $1/kg, hydrogen should be byproduct of electrolysis of sea water with additional products such as chlorine, calcium carbonate ( precursor of cement ? ), other precious metals, etc combined to reduce price of the hydrogen.
It's plagiarizing essays in the same way that I'm plagiarizing dinosaur breath by using the same air molecules.
Show HN: Schedule iMessage Texts from .txt Files
Annoyingly, iPhones don't have a great way to schedule messages. This around 100 lines of python to schedule iMessage texts from .txt files on your computer.

If this is useful to you, please give it a try and let me know what you think. Thanks.
Two superchargers and a half dozen "destination charging" spots in my entire local city+suburbs metro area seems entirely consistent with what you're replying to.

Original poster seeks to articulate that the real cost of AI (whether dollars or energy budget) is best understood not by the price on the sticker alone: tasks not performed by AI might be performed another way, or other tasks might be performed in their stead. Those tasks also have costs. Economic analysis of this should take that into account, and deal with the marginal cost. Original poster laments the lack of models (not AI models) of the alternatives, models that would be used in any well structured attempt to assess this marginal cost.

Poster then offers fragments of a parallel scenario (in which he drives his car) and in which models might also be used. Details of this scenario are not clear to me, but presumably there was some alternative? Unclear.
"Common knowledge" built on cherry-picking data and new alternatives is what we call "fashion".

Also, basing energy supply considerations solely on a dollar cost notion is questionable, even if the dollar cost values were true. It's turning out that 'high nuclear energy cost' FUD is part and parcel of much of the 'green' movement and based on faulty LCOE assumptions that are spread uncritically by self-styled 'greens' on social media.
None. That's my point.

This is way over my head, but I was reminded of The C language is purely functional by Conal Elliott: http://conal.net/blog/posts/the-c-language-is-purely-functio...
Yes, that's certainly how laws work - what a very astute answer, Karellan.

What I'm observing is that the spirit of the law, as it's being enforced here, is what's amusing. Is a suspect's identity deserving of state mandated protection? Only if they're British, I guess.

Why is it so bad to let prisoners have internet access or unrestricted access to a device anyway?

Sure, they can commit crimes with it.

But prisons obviously don't care about their charges committing crimes or they would take serious measures to prevent violence.
> How do you reconcile this with the frame-dragging effect? Namely, in that it shows that the distribution and movement of mass (not just the presence of mass/entropy) can influence the curvature of spacetime and thereby gravitational effects.

If gravity is somehow caused by something like information flow, then a rotating body has an associated rotating flow of information related to the rotating atoms/microscopic degrees of freedom observable at distance. This might have an effect making it distinct from a non-rotating body.

I believe the gradient of a flow field is a tensor, giving gravity tensorial effects as expected.
There are two parts to history: things you remember living through, and ancient history.
I just wrote a blog post and need a graphic to go with it. My options are:

1. Spend hours and $ hiring a graphic designer to make one

2. Spend hours learning/doing it myself

3. Spend time searching the internet looking for images that aren't copyrighted, or spend time finding an image I like and spend time and $ figuring out how to pay/license it

4. Spend a few seconds prompting AI
No, a Klein bottle is an object that can not exist in 3d.
The one you probably know is an "immersion" into 3d (making the object intersect itself, which it wouldn't do in it's original shape in 4d)
Happy to share, thanks!

I also use GPT-4 for explaining the meaning of sentences in more detail (as in JimDabell’s comment). Often my questions are like “how would a native speaker say this colloquially” - I’ve found it really valuable to be able to have a back-and-forth on why something works the way it does

I think it's totally on topic.

I'm surprised more electronics doesn't do it. Maybe it costs to much to manufacture clear casing to consumer spec. Maybe there's no demand among the NPCs

That’s a great link thanks! It really makes it clear that a) correct state changes aren’t automatically correct (there’s both a manual and automated piece and either can go wrong) b) while the language makes it possible, there’s still a lot of manual work involved & footguns (e.g. if you have a contended resource held while something is being migrated, you’re going to experience degraded availability for other sessions to the point of downtime).

> How can the world reach net zero if it keeps inventing new ways to consume energy?

This is the entirely wrong question to ask. We will not be able to conserve our way to net zero. Billions of people in the developing world want to improve their life style. They want cars, air conditioning, and other conveniences that the developed world enjoys.

The energy demand will go up. We need to build massive amounts of zero carbon energy production, storage, and distribution facilities.

The question is not if humanity will find more uses for energy. We will. The question is will we be able to meet the demands without increasing CO2 and if we are realistic and plan on increased energy usage, we will.
> No, the Board determines when AGI is reached.

What if it never arrives?

What if "AGI" is another narrative to fleece investor money to believe in something just to sell out of for as long as possible until they run out of money, investors to throw lots of money on or the lawsuits make it even harder for the company to continue?
it's a bit questionable to claim that AI can be done purely on renewables but painting can't, I think you're forgetting costs (of production, and of eco-friendly disposal (hah!)) embodied in the computing hardware
Thanks for asking. Sorry, I used poor phrasing.

Me too.

I prefer Costco's Darigold Heavy Cream 40% half-gallon. Starts to turn before I can finish it (by myself).

For a while, I'd make large batches of biscuits to use it up faster.

What I meant to say about the coconut cream (milk) is the 13oz cans are more practical for me.

Lastly, elsethread, someone mentioned peanut butter powder. Would love a recommendation. Ideally something without any added sugar.

I appreciate sharing this food / meal prep tips. Every little bit helps, as I'm learning how to "hack" my body.
So strange that currency isn’t considered something useful. I’d recommend “The History of Money” by Weatherford. Innovation in monetary and financial systems are directly connected to human progress and an integral part of it. I’d propose in 20-30 years legacy fiat currency advocates will carry a sense of embarrassment trying to explain why they defended such an abusive system based on confiscation and war with a record of death and destruction and collapse, over a system with transparency and fairness that promoted the greatest expansion of clean global energy imaginable and helped end the endless tribal warfare between nations. But yeah … nothing useful.
Interesting it was in the UK, I was expecting Australia or Quebec where I think geological finds tend to be much older.

I think the regulations are changing as people understand what to change, but the construction problem is still a problem.

We are bad at construction, and productivity in the entire sector has been stagnant for half a century. In the meantime, we have seen soaring productivity in manufacturing, meaning that labor costs go up too, but without the corresponding productivity increase.

For a nuclear peoject, where so many of the very high up front costs are labor, this is devastating to the cost structure.

And of course, delays are devastating to costs when financing costs are more than 50% of the cost of the entire project.

Fix construction, and maybe nuclear will make financial sense. But not until construction is fixed.
Socialism and its more authoritarian affiliates are not kindness. They bear false witness in economics, consolidate social power, crush the human spirit, and typically end in nihilistic, untethered depravity.
I don't get why this would be someone's position. If it "barely works" it would not sustain mass usage across many product lines.

Just recently, I used generative AI integrated into databricks to build complex sql queries via English, used Google Gemini in Google sheet to formula a tricky pivot table, chatGPT build a cloud formation schema for new infra for a service & to navigate some tricky database primarily key setup for dynamodb; used copilot integrated into my IDE to speed up unit test and simple refractors and code complete every other line written.

I nor the other millions of subscribers to these tools are not subscribed because it barely works it's because it lets me work more efficiently.

It save tons of time across many product for many things that used to be sources of frustration or slow mundane tasks.
Hi HN, I’m currently sitting in a testing center right now, and the technicial issues are real. Among other things, the testing app needed a last minute update, the preloaded test on the app failed to load for everyone, and the Wi-Fi is down/at a crawl from people using it to download said update. This is fun.
Ask HN: Isn't AnthropicAI Claude 3's price too expensive?
The API is really expensive, but even the app is priced more than it's worth it.

At $20 you don't get:

- code interpreter

- custom instructions (system prompt)

- plugins

- internet browsing

- ability to create your custom GPT/bot

- iOS app

- voice input and output
Topological Duality for Distributive Lattices: Theory and Applications
Palestinians should get their land back. If Israel refuses to give it back then the US should take away their WMDs. Israel has undeclared nukes and the only active offensive biological and chemical weapons programs. This is unacceptable.

Also, I would like to point out just how outrageous it is to imply that the indigenous people of a land don’t have any right to it themselves because they have regional allies who support them. What a completely backwards and insane misrepresentation of the situation. Just using the word “hold” implies it doesn’t belong to them in the first place.
Not everyone is accusing the doctors involved, but when I wrote the comment, there were numerous armchair expert opinions squarely blaming the doctors, including at least one who said that doctors limit the number of training slots available to keep their prices high. Thankfully, those perspectives have been addressed or at least outpaced by better thought out criticisms since then.

Ultimately, the number of training slots in the current system is limited by MHA and MBA administrators who see training and instruction as subservient to profits, not the doctors who make up the departments and training faculty. Or, more broadly, they are limited by the healthcare operations not being legislated in a saner way. I was just clarifying.
There’s no free lunch and I’m suggesting the trade offs to support this are not worth it vs simpler approaches of doing a graceful drain & upgrade approach w/ a timeout for long running sessions if those may exist (+ if you have a lot of large state to migrate, it could be insanely long to complete an upgrade). This is because availability will never be 100% anyway in any scenario and this kind of transition can easily fit within your failure budget.
dropdowns don't work in firefox.
IANAL and I haven't dug deeply into the lawsuits, but my understanding is that using deliberate prompt engineering, they were able to get it to reproduce copyrighted material verbatim from its training set. That is obviously a problem, just as it would be if a human read the article and then reproduced part of it verbatim without attribution, but it's a very different argument than a blanket "everything AI generates is plagiarism"
How many people processes do you currently interact with that "barely work".

- Call Customer Service, go through a crazy flow chart and be redirected to 10 different people.

- Go shopping, sift through thousands of reviews/images/fake products to find one that works.

- Manually create graphics/designs for unique rooms

- Request a junior employee to write some basic code.

- Request a junior employee to perform task X.

The AI also has the advantage that it can scale up to 24/7, on-demand work without an additional engineer.

Waymo has to do an interesting dance with municipalities where it wants to be cooperative, but not let the municipalities think they have authority that they don't.
Bitcoin is especially obscene because it counteracts efficiency gains. If a new Bitcoin miner that is 10x more efficient for hash rate comes out, Bitcoin won’t use 10x less energy, instead the difficulty will get 10x harder so it continues using similar amounts of energy.

With AI, on the other hand, efficiencies help. Of someone comes up with AI hardware that does inference or training 10x more efficiently, people will incorporate that and the energy usage for the same amount of work will decrease.
I'd look at this from a different perspective. Why does one hire a janitor? Is it because you're incapable of cleaning a bathroom, mopping, or sweeping? No, it's because you have different priorities for your own time. Even if software capable of creating software, flawlessly to specification, was created - software developers would still have a job. Creating those specifications (and handling ambiguities), integrating the resultant product, dealing with ever-changing specifications, and a zillion other things will still be around, and probably always will be.

If anything, software based solutions (LLMs or perhaps something more domain specific and accurate, eventually) will just broaden the labor pool for software. So you'll see more people enter the field which will depress wages, but there will also probably consequently be more jobs.
One cannot take seriously people that use the most extreme outlier event in the history of a technology as a generally representative data point for said technology.
"annoyed, because you are yet again interrupting what I had been serenely thinking about, by asking how I feel"
Anders Larsson here, and today I want to share something crucial with my fellow digital content creators and affiliate marketers. If you've ever felt lost or overwhelmed by the plethora of affiliate marketing platforms and strategies out there, it's time to go beyond surface-level advice and truly understand what works and what doesn't. Today, we'll be taking a look at OG Ads versus CPAGrip, two major players in the affiliate marketing industry, and why my journey through trials, errors, and realizations is worth your attention.

Important to note is that the affiliate marketing space is filled with hurdles that require determination and perseverance. I've been there, hitting refresh over and over, hoping to stumble upon that next big strategy. So I share this to help you avoid the mirage of broken promises that I've encountered. This video might help you determine if what's being discussed on forums like BlackHat World is of any value to you or mere noise.

We dive deep into the realities of OG Ads and CPAGrip, deciphering the actual experiences of users beyond the claims and numbers. Some users seem to have success, while others hit dead ends despite significant clicks. This means that there are underlying variables that affect success—such as audience region, device preference, and traffic quality—factors that often get overlooked.

However, let's be real; we've all pursued paths that turned out to be wrong. Feelings of endless cycles and dwindling motivation can be all too familiar. The secret? It's not just about the platforms but understanding the nuances that make a strategy succeed.

This video discusses those nuances and will guide you through a genuine understanding of how to leverage the strengths of affiliate marketing platforms. It's not about quick fixes—it's about sustainable streams of passive income and aligning your efforts with strategies that genuinely work.

So why am I sharing this? Because I want to offer you the education that transformed my life. I'm providing my free video training for those interested in learning more about building a solid foundation in affiliate marketing. Below is the link to this free resource, and if it piques your interest, there's also a direct path to the education platform that has been instrumental in my growth.

This isn't just another video; it's a pivotal point of learning. It's distilled knowledge, coming from a place of earnest experience. Check out my free video training, and learn from my journey.

And remember, engaging with this content is not just about gaining knowledge—it's about implementing what you learn for long-term success. If you find value in this discussion, don't hesitate to click the like button, subscribe, and click the bell notification so you won't miss out on any future content from me.

Stay awesome, take in the knowledge, execute on it, and I'll see you in the next video. Bye-bye!

Again, I'm not certain of the entire stack beyond my house, but the device they brought for installation was sealed in the box that said "Media Converter" (not "ONT") on the box. It could still be the case that they somehow set it up remotely, or it could be that no setup was needed. For all I know, I tested my connection with PPPoE.

For experienced professionals that know what to ask and use the tool as a Google-on-steroids to avoid writing a block of code themselves, I can understand.

But I worry that lack of education for younger devs (and other folk for that matter) about the dangers of over-delegating to AI is going to be a major cause of decline in analytical capacities.

The three mile island incident singlehandly shows that US' concern should be correlated to other countries nuclear incidents. Thinking that it only arrived because of "communism" is quite wrong, especially because of the technical capabilities of the USSR.
I use GPT-4 for this kind of exposition too. If you haven’t come across Pleco [1] yet, I can highly recommend it. It’s a high quality Chinese-English dictionary with a lot of helpful features for reading Chinese

One feature I use a lot is the clipboard reader, which lets you step through Chinese text character by character and shows you the meaning of each character. It can be faster than using an LLM, but you don’t get the whole-sentence meaning or the ability to ask follow-up questions like you can with an LLM. But it’s a great app all round (some features are paid)
