atwrk··on Pebble Index 01 – External memory for your brain
BTW this also works the other way: I find myself to avoid US products more and more because they tend to come with inbuilt obsolescence, or, for digital products, with dark patterns preventing subscription cancelling.

$100 put into S&P 500 in 1975 would be about $7500 today, or about $1250 in 1975 dollars.

$100 put into gold in 1975 would be about $2600 today, or about $440 in 1975 dollars.

S&P 500 would have had 3x the returns of gold.

I find it very telling that both Samsung and SK Hynix already stated that they don't plan to expand capacity - officially to prevent overcapacity in the future. It would also be plausable that both doubt OpenAI will follow through with the contract.
atwrk··on Japan's gamble to turn island of Hokkaido into global chip hub
This is about international relations. You won't get any insight into it if you reduce any point you don't like to argumentative metaphors.

Even within the framework of (structural) realism so popular in contemporary US politics there's this well-known problem that the buildup of defense capabilities of party A looks like aggression to party B - and vice versa. See the seminal work Perception and Misperception in International Politics. Or the relations of Britain and Germany before WW1 and WW2.

The FP article I mentioned, "Trump’s Trade War May Make Elite Young Chinese More Nationalistic" [1], illustrates the argument. You have actual empirical data, changing over time, after exposure to the "treatment". So at least a hint of causality.

atwrk··on Japan's gamble to turn island of Hokkaido into global chip hub
No. I pointed out that both the "by force" statement for China and the "Taiwan doesn't want" statement are so oversimplified that they became factually incorrect. The "logic" is your inference and neither stated nor implied by me.
atwrk··on Japan's gamble to turn island of Hokkaido into global chip hub
Both points are not really true.

For the China part: Yes, the "by force" part certainly exists as a position, in competition to the peaceful unification approach. It's important to keep in mind, though, that the confrontative position of the first Trump administration and afterwards the Biden administration significantly helped the "by force" faction. There was an interesting piece in Foreign Policy about that, a social scientist from the US was questioning Chinese students at an elite university on this very topic and thus had the chance to do a time series observing the attitude change following US actions.

Secondly, in Taiwanese politics, Unification is actually a big topic and even has its own party, the New Party, advocating for it (plus the fringe CUPP). Not popular right now, but certainly existing - and evidently falsifying the notion that the all of "Taiwan doesn't want to be part of Beijing's China".

atwrk··on Tesla Robotaxi had 3 more crashes, now 7 total
How many crashes per mile for Waymo etc. would be the more interesting metric - if the competition has better numbers there is no excuse for risking people's safety with inferior tech

All Sparks only have a memory bandwidth of 270 GB/s though (about the same as the Ryzen AI Max+ 395), while the 3090 has 930 GB/s.

(Edit: GB of course, not MB, thanks buildbot)

atwrk··on Drilling down on Uncle Sam's proposed TP-Link ban
As someone from Europe, I certainly am at least equally uncomfortable with products from the US. Made in USA to me equals zero concept of privacy protection but plenty state surveillance (CLOUD Act, Cisco having hard coded back doors every two weeks etc.) and recently even lack of rule of law and even threats of annexation of European land and interference in domestic elections.

Sure, China will probably also spy and conduct industrial espionage, just as the US, but they appear to be a rational actor and have never threatened the sovereignty of European countries.

Because people will be deeply affected by this, and not in the positive way. We already had this with copilot: https://i.imgur.com/nguIAsv.jpeg

Just as with copilot, this combines LLM's inability to repeatably do math correctly with peoples' overassurance in LLM's capabilities.

atwrk··on Apple Vision Pro upgraded with M5 chip
What makes you think the Quest 3 is discontinued? The 3s was clearly communicated to be the cheaper alternative (and replaced the Quest 2 that was still sold in parallel with the 3), not a replacement for the 3.

That's silly, most modern democracies are organized federally and don't have this issue.
atwrk··on The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2025
> It is not falsifiable because it is not a hypothesis but a framework for recognizing science.

And if the source of that framework is not (part of your definition of) science, how do we know whether that framework is true?

That was sort of my point: Poppers criterion is nice, but only works for a small subset of (natural) science - and even there has to face criticism because it is simply too naive for many edge cases.

On top of that it only works in the VIS range, thanks to the filters in front of the camera sensors - and most of the interesting information is in UV or IR. VIS only contains information about a few elements. (see Fraunhofer lines https://en.wikipedia.org/wiki/Fraunhofer_lines)

> I haven’t measured it but I read that I should expect it to lose 3-4% in suspend every hour. Is that a joke?

That has to be a bug. I have a thinkpad with a Ryzen 7 6850U, running debian, and lose at most 3% per day.

atwrk··on US High school students' scores fall in reading and math
West Virginia is a nice datapoint here: Almost completely white, but also poor. And one of the worst scores of all.

Why do you assume racial achievement gaps indicate problems with schools?

GP didn't say that, but educators of course see schools as an important area to address the gap. The literature is pretty clear on this being a complex problems with schools being an important wedge to break the vicious circle.

Re point 2: In Germany, among other countries, you have social education workers (a college-educated job) in school for these situations. Such behavior has underlying causes, e.g. problems at home (fresh divorce, drugs, poverty-related stress) recent trauma (accidents, death of a loved one, abuse), mental illness (AHDS etc.). Treat the cause and the behavior changes.
atwrk··on Like Intel before it, AMD blames motherboard makers for burnt-out CPUs
Apple is the only company where I ever had to involve a lawyer to exercise my consumer rights (in Germany). They made notebooks with a design flaw that resulted in broken display cables from opening and closing the devices. My notebook broke 3 times, and at the third time I have the right to get my money back, which they refused (before involving said lawyer).
atwrk··on Ask HN: Why hasn't x86 caught up with Apple M series?
This is Cinebench 2025, a cross platform application: https://imgur.com/a/yvpEpKF

You sure like that table, don't you? Trying to find the source of that blender numbers, I came across many reddit posts of you with that exact same table. Sadly those also don't have a source - the are not from the notebookcheck source.

atwrk··on Ask HN: Why hasn't x86 caught up with Apple M series?
To me it simply looks like Apple buys out the first year of every new TSMC node and that is the main reason why the M series is more efficient. Strix Halo (N4P) has, according to Wikipedia, a transistor density about 140 MTr/mm2, while the M4 (N3E) has about 210 MTr/mm2. Isn't the process node alone enough to explain the difference? (+ software optimizations in MacOS of course)
atwrk··on Tiny microbe challenges the definition of cellular life
Because in most cases the categories are invented by us, to make sense of the world. But the penomena themselves are often continuous. Or actually not just us but most life with some kind of sensory system - even paramecium differentiates between food and non-food.

Take our color perception as an obvious example: We clearly see different types of color, despite us being unsure at the thresholds in between, and the actual electromagnetic radiation of visible light being a continuous wavelength range.

That is just a fundamental limit of our reasoning. We mentally make models of the world to make sense of it. These models have to be of less complexity than reality, ergo they have to cluster perceptions, ergo we have to categorize.

We don't have to rely on anecdotes, we have large amounts of empirical research. Just hop over to pubmed and search for yourself - the connection between psychedelics and psychosis is really weak, unless you have a known family history of schizophrenia etc. Yes, it exists, but it really isn't that common.
atwrk··on Staying cool without refrigerants: Next-generation Peltier cooling
There are many applications for peltier cooling in industrial settings, i.e. sensor devices (or, actually, microscopes with CMOS sensors). Those have to be temperature stabilized to minimize noise while also be IP rated, i.e. no air cooling. 75% efficiency gains would be awesome here.
