The difference between Deepseek-r1:70b (edit: actually 32b) running on an M4 Pro (48 GB unified RAM, 14 CPU cores, 20 GPU cores) and on an AMD box (64 GB DDR4, 16 core 5950X, RTX 3080 with 10 GB of RAM) is more than a factor of 2.

The M4 pro was able to answer the test prompt twice--once on battery and once on mains power--before the AMD box was able to finish processing.

The M4's prompt parsing took significantly longer, but token generation was significantly faster.

Having the memory to the cores that matter makes a big difference.
But the Turing Award is for his technical work.
This is what happens you feed the ego of software engineers. Make them think they are smarter than everyone else and that they cannot be wrong simply because they are good at software engineering.
You are a candle in a dark windy gale. Power is not a job it is made of people. The modern way of life has eroded our foundations for self rule and we awaken to delegated power not working how we had hoped.

It’s a long hard road with a lot of work within, which never begins until you let go of the comfortable lie of modernity. Those you think are your enemies are full pro on this power thing. The damn shame is, the greater enemy are those who will play your “sides” against one and other, though we all have our issues.

I hope this war ends soon favorably for the Ukrainians. Trump is tacking this down as a tough business deal. Different kind of war than Zelensky’s experience. They could get fleeced.

In your mind you were just comfy and now you notice virtue is collapsing somewhere in the world. The war isn’t where the bombs drop, it is everywhere this damn mechanation of power presses upon us. Which for modernity is by umbilical.

If you cannot see what I mean for yourself, just do extra sit-ups and pushups and don’t be the slob when the yolk of civilization falls upon you and yours.

Theft does not imply the use of force. It is illegally depriving you of your property (regardless of whether force is used).

However, tax you owe is not your property in the first place. It's the price of living in the society you benefit from. You can complain the price is too high, or go live somewhere else. But it's not theft.
I couldn't speak to Outlook, but Outlook is both popular enough and has enough people locked-in to its ecosystem (as business users) that it doesn't have to worry about losing users if Accept-Language doesn't do the right thing. Companies have IT departments to fix that stuff.

I'm talking more like https://www.buerklin.com/. If that site comes up in the wrong language and the only way to fix it is to change the user agent's Accept-Language header, the user isn't going to just figure it out; they're going to navigate elsewhere. So the site has a bug in the top-left to toggle English or German.

Something you mentioned up-thread that I should have commented on but overlooked:

Which is a bigger amount of compute, "max" or "ultra"?
So now the TOPS are not comparable because M3 is much slower than an Nvidia GPU? That's not how comparisons work.

My numbers are correct, the M3 Ultra has around 1 % of the TOPS performance of a RTX 5090.

Comparing against the GPU would look even worse for apple. Do you think Apple added the neural engine just for fun? This is exactly what the neural engine is there for.

It's a shared computer in a hospital used for research data management. Basically, every time I walk up to it to use it, it's turned off.

Maybe Apple should remove power off from the UI menus if they're claiming it uses less energy to leave it on.

(I'm dubious of that claim people are repeating here, but what the hell do I know I'm just a physicist. Reality distortion isn't my thing.)
Indeed. The M3 Ultra is in the midrange where they duke it out. Similarly, for its niche, the iPhone CPU is was better than AMD’s low end processors.

Anyway the Apple config in the article costs about 5x more than a comparable low end AMD server with 512GB of ram, but adds an NPU. AMD has NPUs in lower end stuff; not sure about this TDP range.
>Yeah I think when they say non-tech people they mean a subset of people who know a bit about refresh rates (example being avid PC gamers for instance)

no, he didn't say that. he said they comment on the difference between apple and android (their perception). you have to take that as a given.

that "it's because refresh rate" is his hypothesis, so yes argue that, but not by changing his evidence.

Western Europe still has a massive manpower advantage, before you even look at investment and . If things develop to the level where the "comfortable city dwellers" in Europe is truly threatened I don't see Russia as being anywhere near the victor (though you're correct that in that case there won't be a "victor" so much "Might Lose A Little Less"). But the goal is to push up to that limit but no beyond, at least for now.

I don't think many people are actually nationalistic zealots who want to eliminate other countries so long as theirs is technically still existent, as even a king of ashes won't have a great life compared to a mid-range billionaire today.

Struct generics in C# are monomorphized - exact same as in Rust.

Combine that with pattern matching and you can go quite far. In place of macros you can use source generators, although they are both weaker and stronger than proc macro depending on what you use them for.
The M3 Ultra is the only configuration that supports 512GB and it has memory bandwidth of 819GB/s.
> also repetition of different explanations of the same concept.

multiple encodings are stronger since they end up fusing into not just more robust and general representations, but also more well connected.

i forgot which neuroscience textbook it was that I read all this from from, but Dr. Barbara Oakley talks about this in her course too so anyone can look through there for more details and sources.

> desirable difficulty

Well regarded in anki, music practice, and most problem solving books (Polya's "How To Solve It"). I think some neuroscience texts also try to formalize it but I don't know enough there to point to a more concrete abstraction of the phenomenon.

> As you re-read the explanation

I suggest something even better. Try to do the explanation yourself from free recall, and when you fail, then re-read and note exactly where and why you failed. This is a mid-level efficiency technique (I forgot the source) compared to free call, active testing, and spaced repetition, but definitely better than plain re-reading.
It feels a bit like we entered the “consumer grade workstation” era a while back when AMD started selling 16-core CPUs that will happily socket into run of the mill consumer motherboards and that continued with the higher end M-series SoCs.

It really is cool to see. It’s nice that that kind of horsepower isn’t limited to the likes proper “big iron” like it once was and can even be reasonably be packaged into a laptop that is decent at being mobile and not an ungainly portable-on-a-technicality behemoth.
The problem is, the oil tankers are single wall, shoddily maintained, probably contaminated with all sorts of nasty stuff and with barely any history records. These things are effectively floating time bombs - assuming you can find a buyer for the seized cargo given the lack of paperwork in the first place, you need to sell the ship for scrap because it's nowhere near seaworthy (remember: single wall, no Western insurer will handle that), and that costs a loooot of money if you are a Western country and can't just haul it off to Alang [1] or whatever place and let others deal with the fallout.

It's fine to be wary. It's dumb, naive, or reckless not to do the work and analyze whether or not the fear is warranted in a specific case. Adam Curtis did the work in a specific case and found the fear unwarranted for that specific case. Parading that example has no fucking relevance for this specific case except to say that someone always has an incentive to lie about something.

The people abiding by the principle "strive for peace, prepare for war" are not "scary scared people" despite being very afraid of war on some level.
That's still not even competitive with 100G Ethernet on a per-port basis. An overall bandwidth of 480 Gbps pales in comparison with, for example, the 3200 Gbps you get with a P5 instance on EC2.
I think it's highly unlikely that the M4 mac is actually limited to 60Hz for all external displays. I'm running a 1440 ultrawide at 100Hz on an M2 right now. Instead this is likely the maximum px*Hz configuration supported, and smaller or fewer monitors are supported at higher Hz.

That makes a lot more sense. It also matches the times they record for the exercise. For context, 2.92 is:

> Exercise 2.92. By imposing an ordering on variables, extend the polynomial package so that addition and multiplication of polynomials works for polynomials in different variables. (This is not easy!)

2.29 is what I described in my other comment, it's a pair of functions walking a binary tree with conditional logic based on if it's an interior or exterior node, returning either a sum or a true/false value. Which is not hard at all and their time was only 83 minutes. Versus their claimed time of 2400 minutes for 2.92.
Since the GH200 has over a terabyte of VRAM at $343,000 and the H100 has 80GB that makes that $195,993 with a bit over 512GB of VRAM . You could beat the price of the Apple M3 Ultra with an AMD EPYC build.
Yes. I have maintained my ledger with beancount for 5/6 years now. I don’t automate downloading from my bank, it’s not worth the hassle especially now that every login requires 2FA with my phone.

But I did write an importer for the csv files my bank provides and with smart_importer I don’t even have to categorize the statements anymore (although there are mistakes sometimes).
I don’t gather metrics though , I use fava to have a visual view of my books.

I usually spend half an hour per month maintaining the ledger .
It's only a super power if you're buying those services instead of providing them for a profit (99.9%).

I wonder if lunar space elevators might be the fix here. If I understand correctly, such an elevator would not be as subject to the perturbations since the tension would keep it's orbit stable (is it still an orbit if it's tethered?).

Another option might be a LORAN style system put up on towers. With lower gravity and no atmosphere I imagine we could stick transmitters up very high without super complex construction, maybe even just a giant carbon fiber tube with a transmitter at the top.
Love digging around projects like JOS. I had never heard of it before, and there really doesn't seem like much else online about it beyond the info that can be found from that link. There's always something melancholy about retroactively watching the activity of a project like JOS have such a swarm of activity and then just quietly and unceremoniously dying off.
Thanks for the feedback! Are you viewing Scholium on a mobile device? If so, that was definitely an oversight by me and thank you for pointing it out!

Technically, satellite positioning only needs 1 satellite. GPS requires several but one of its forerunners was Transit[1] which I believe only needed a signal from a single satellite at a time. It worked by measuring the doppler shift of the signal coming from the satellite. Of course that only works if the orbit can eventually cover all (or much of) the surface and for all I know there is no such frozen orbit for the moon. Also, it would still presumably require extensive surface-based tracking and correction.

yup, I bought a 13 mini and was happy that Apple was one of the companies that supported this form factor. That being said, the 13 mini sales numbers speak for themselves and I understand why this kind of phone isn't released every year. I'm holding out that Apple recognizes that most of the users of the 13 mini aren't serial upgraders and will continue refreshing the segment every 5 years or so

It is much slower than nVidia, but for a lot of personal-use LLM scenarios, it's very workable.

Agentic Earth Observation
Satellite data is abundant, but extracting meaningful insights from it remains a challenge. Accessing imagery is one thing—deriving answers from it without extensive technical expertise is another.

To explore a better approach, I built a proof of concept that converts natural language queries into structured SentinelHub requests. The idea is simple: instead of manually navigating APIs and datasets, a user should be able to ask, "What’s the NDVI trend in Muzaffarnagar over the past year?" and get a meaningful response.
I'd be really curious on how hard programmatic access to your own, personal banking data might be in the PSD2-era.

I can link my secondary bank account to my main bank's app so I can see the balance in one place, but the catch is that I need to refresh this authorization through the app every 90 days.

Ideally, you'd just use your banking credentials to authorise the API access and pull data through that. What this requires in practice, I have no idea but it probably involves a bit of bureucracy.
so, we’re observing the same things, but drawing opposite conclusions.

A box on a farm means much MORE handling of it, no? Currently no farmer I’ve met has ever handled pure ammonia, only UAN or nitrate/other dry solids. And like you said, they’d rather not. (although I also don’t know any who would drink glyphosates with how quickly they eat sprayers)

How does a box help with timing? Each farm must either store enough on site for an entire application (which farmers could already do if that was worth the cost) as it’s slowly generated, or they’re constrained by daily output of the box. Late shipments are bad, but a renewable only box running out on a cloudy week? No angry phone call to the coop fixes this.

Spreading the cost to centrally produce and store lots over many farms/industries seems optimal when one needs infrequent but huge quantities of anything.
> I don’t get it. Are people just lying or is there a secret tool that is 100x better than anything I can find?

They are just lying. They have to sell their product some way and the CEOs and sales people are the perfect suckers because they have no idea what coding is.
Ask HN: Receive Payments as an Independent Contractor
Hello,

I'm an Iraqi software engineer, working as an independent contractor for a US-based startup. I've been with the same company for 2 years, and I've faced lots of difficulties receiving my salary. My employer has been very patient and flexible with the whole situation, however, I'm out of alternative solutions, and I was looking for your help.

Things I've tried so far:
* My employer used Plane (Formerly Pilot) as an EOR and payroll solution, I added in my local bank and transfers were being made there. Plane stopped sending payments to Iraqi accounts.

* I started using MoneyGram and WesternUnion and after a while both got sanctioned locally.

* I started using my cousin's Turkish bank account, and once he was receiving the payment he was forwarding it to me using a middle man, however, the process was cumbersome for my cousin to do and eventually his bank asked him where the money is coming from, which put us in a difficult spot.

At the moment I'm fully stuck, we thought about crypto, but I have no idea how that works! I can sell crypto p2p on OKX and Binance, but my employer can't make a payment there he can make a payment to Coinbase though which I can transfer to Binance or OKX and use a p2p trade.

But, I'm sure there's a better alternative and that's why I am here! I would REALLY appreciate it if you provide me guidance.

To see it as an advantage, you have to be sure that your community is active enough to write complete documentation with the new name.

It looks pretty bad when you look for documentation and people have to tell you to search for documentation with a different project name, because the name was changed.

For instance, whenever you want to do something with MapLibre, you have to think whether you should look at the Mapbox documentation or not. Many times it's confusing. But it is explained by the fact that there was an actual need for a fork, and hence a new name.

Sure luck plays a role. There are techniques to increase your odds of getting lucky though.

Sam Altman argued a startup's chance of success is “something like Idea times Product times Execution times Team times Luck, where Luck is a random number between zero and ten thousand”

A lot of the success in startups is not due to getting the initial idea right, but what founders do once they realize that their initial idea is wrong.
