A little tangential/OT, but one of the things I admire about Andy Gavin and the Naughty Dog team is that they were capable of doing things on a brand new system that few ever figured out how to do.

Usually when a new system/console comes out it takes a while for developers to get used to its quirks and figure out optimizations and hacks to eke out whatever little performance gains you can under the constraints of the hardware.

One of the first games for the PS2 was Jak and Daxter: The Precursor Legacy, developed by Naughty Dog. What is remarkable is that Gavin had figured out that a lot of the assets and textures etc. that needed to be available in order to start the game could be loaded while the typical splash screens were displayed at the beginning.

I never noticed it when I played the game years ago, but I picked it up a while back and had a "wait, what?" moment when the PRESS START button appears, and instantly upon pressing it you're launched into the game and can interact with the world. No loading screen, no cutscene, just straight into the game.

Anyway, mad respect for a small team that managed to produce some of the most beloved games from that era.

Long time knitter - this is genuinely interesting. I’m trying to think of a killer use case for this, because scaling this up to create something for production looks pretty hard to me, or at least like it’s going to take 5+ years, and that’s if this team works with one of the big Japanese knit-in-the-round hardware companies.

That said, I love the idea of specifying and being able to knit in 3D. We just need a brilliant designer to come up with something that would be really great to have knit and can’t be knit with traditional techniques. And like six revs of the hardware for scale, tensioning, yarn size, etc.

Anyway - really cool.

As a counter anecdote, I have a lot of SSDs from the late 2010s that are still going strong, but I lost some early SSD drives to mysterious and unexpected failures (not near the wear-out level).

Right, in an ideal world we'd peer into the minds of people and compute what they know. But if we did that, our eyes would probably catch on fire like that lady in Kingdom of the Crystal Skull.

We need some way to distill the unbelievable amount of data in human brains into something that can be processed in a reasonable amount of time. We need a measurement - a degree, a GPA, something.

Imagine if in every job interview they could assume absolutely nothing. They know nothing about your education. They might start by asking you to recite your ABCs and then, finally at sunset, you might get to a coding exam. Which still won't work, because you'll just AI cheat the coding exam.

We require gatekeepers to make the system work. If we allow the gatekeepers to just rubber stamp based off of if stuff seems correct, that tells us nothing about the person itself. We want the measurement to get close to the real understanding.

That means AI papers have to be given a 0, which means we need to know if something is AI generated. And we want to catch this at the education level, not above.

> Meanwhile a memory issue in C/Rust and even Go will immediately drop every assumption out the window, the whole runtime is corrupted from that point on.

In C, yes. In Rust, I have no real experience. In Go, as you pointed out, it should segfault, which is not great, but still better than in C, i.e., fail early. So I don't get or understand what your next comment means? What is a "less lucky" example in Go?

Not just focusing only on what they want us to hear is a good thing, but using more noise we knowingly consider low value may actually be worse IMO. Both in terms of the overall discourse but also in terms of how much people end up buying into the positive bias.

I.e. "yeah, I heard many counters to all of the AI positivity but it just seemed to be people screaming back with whatever they could rather than any impactful counterarguments" is a much worse situation because you've lost the wonder "is it really so positive" by not taking the time to bring up the most meaningful negatives when responding.

Sorry, I mend to say: Even if a grammar is not ambiguous, it can require unbound look-ahead to be parsed correctly [1].

The grammar of C is ambiguous. The statement "a * b;" can be both parsed as a variable declaration of the variable 'b' of type pointer to 'a' and as an expression consisting of a multiplication of 'a' and 'b'. It all depends on whether 'a' is a type or not. In most cases it would be a type definition, because why multiply two variables and ignore the result. One trick to deal with this is to give precedence for the type declaration grammar rule over the expression grammar rule. However, this is not something that can be done with many parser generating tools.

Yet the first C compiler where single pass compilers with a single look-ahead lexical token probably implemented as a recursive descent parser. It worked, because it kept a (reverse) list of all variable declarations, which allowed it to determine when 'a' was parsed if it was the start of some declaration or the start of a statement based on whether it was defined before as a type or not.

Micron Fab 6 is about 2300 staff (including 1000 contractors).

Even if you pay them all 500k per year, that's "only" about a billion a year in payroll.

The New York fab plan costs something like 20 billion more or less now to build, with 100 billion over 20 years.

Also, maybe the calculus is different right now in the US, but it used to be the semiconductor workers were expected to have PhDs coming out of their ears but were not actually paid very well, with salaries in Taiwanese fabs being around the $50-60k mark, and lower paid workers being more like $20k or less. Presumably US fabs will be automated to an even greater extent due to labour costs.

So it's very possible that servicing debt on the capital outlay is substantially more expensive than the payroll.

The argument of technical impossibility seems implausible, although it would no-doubt be difficult. Whether there can be enough engineering will mustered within the company to separate out the AdTech stack from the rest of Google's services is another question.

In terms of how the AdTech stack could look afterwards, here is a paper (I authored) advocating for the introduction of an interop layer such that users could choose which advertising network to use with Google's products and services: https://doi.org/10.36633/ulr.1113

>> Also profoundly grateful for vaccines.

Yup

Sadly, I've seen many online arguments resembling "humanity survived millennia without vaccines, why do we need them now?", obviously entirely ignorant of the consistently extremely high childhood death rates, where a couple was very lucky to not have to mourn half of their children. As the article pointed out,

>> "In early modern Europe, almost 50% of children did not live beyond age 15. Around a quarter of infants died before their first birthday."

All one needs to do, at least in New England where I live, is visit an old graveyard and notice that among the pre-1900 markers, the vast majority of gravestones tell of a very short lifespan, many only mere months.

Those same anti-science dolts would be screaming for someone to do something if their children died at such appalling rates, but with willful ignorance declare they know better than literal armies and generations of scientists, medical researchers, and epidemiologists.

As Carl Sagan pointed out, they think their ignorance is better than the scientists' hard-won knowledge.

This anti-science ignorance is a serious issue for any society, and the tension between deliberate ignorance and hard-won science being put on equal footing.

Nothing against multi-process models, though I note they're far more common on non-Windows, other than browsers. But why on earth is it necessary?

I wish they'd give it a redesign building it the old fashioned way with the Windows API.

Problem is we don't have any good data about which gravitational accelerations would be suitable for long term health. We have 1g as our baseline, and we know that months in 0g messes you up and longer is a bad idea. We don't know anything about the long-term effects of living in Mars or Lunar gravity though. It could be studied using von Braun stations, but nobody has done it.

Harumi is a new startup aiming to make operations research (OR) accessible to companies that don’t have in-house optimization teams. Their platform lets businesses model and solve problems like production planning, scheduling, logistics, and routing using OR + AI without heavy custom consulting.

Why it’s interesting:

OR is powerful but historically hard to adopt; Harumi tries to productize it.

Strong applicability: manufacturing bottlenecks, workforce scheduling, supply chain efficiency.

They integrate with open-source solvers (GLPK, CBC, HiGHS), giving flexibility.

Recently raised ~$550–600K and is growing out of the Brazil/LatAm ecosystem.

Potential challenges: integrating OR into real-world workflows and competing with established players. But if they succeed, they could make optimization tech far more accessible.

Curious if anyone on HN has tried similar tools or sees demand for OR-as-a-service in their org.

Both the EU and the US have introduced face scanning at airports to "increase security". EU rules are currently stricter and US rules allow some opt-outs for people that are uncomfortable with it. But it's only a matter of time before it becomes de facto mandatory for everyone. They claim that data is not retained or shared with other parties. Yeah, right, I totally believe that... Can something be done about this? I'm convinced that very few customers think face scanning is an improvement.

That and water. Electricity: Google made a post about scaling k8s to 135.000 nodes yesterday, mentioning how each node has multiple GPUs taking up 2700 watts max.

Water, well this is a personal beef, but Microsoft built a datacenter which used potable / drinking water for backup cooling, using up millions of liters during a warm summer. They treat the water and dump it in the river again. This was in 2021, I can imagine it's only gotten worse again: https://www.aquatechtrade.com/news/industrial-water/microsof...

Europe has played a foundational role in the development of the foundations of modern computing - Linux and ARM are prime examples of technologies that have reshaped the industry over the past three decades. The question isn’t whether Europe should distance itself from American technology, but why US firms have been far more successful at monetizing Europe's innovations. I'm afraid they're going to have to do some soul-searching to understand why upstart businesses have a difficult time flourishing in Europe.

This behavior has practically nothing to do with Labradors. Many, many dogs regardless of breed can do this. Cats too. And foxes and wolves and rats and... well pretty much all quadrupeds with reasonable sizes limbs relative to their body. You might notice it's more or less the same motion as walking. Animals that drown usually do so from exhaustion, not because they can't keep their head above water.

Primates are relatively unique in their complete lack of innate swimming abilities.

That's kind of the opposite of what I mean. CLAUDE.md is (ostensibly) always loaded into the context window so it affects everything the model does.

I'm suggesting a POTENTIAL_TOOLS.md file that is not loaded into the context, but which Claude knows the existence of. That file would be an exhaustive list of all the tools you use, but which would be too many tokens to have perpetually in the context.

Finally, Claude would know - while it's planning - to invoke a sub-agent to read that file with a high level idea of what it wants to do, and let the sub-agent identify the subset of relevant tools and return those to the main agent. Since it was the sub-agent that evaluated the huge file, the main agent would only have the handful of relevant tools in its context.

I wonder how hard—technically/legally, not 'politically'—it would be to create a 'neutral' streaming service where all the major studios and IP holders could become a part of as a part of a co-op (?).

After costs are taken care of, the holder of the IP would get the leftover profits proportional to the number of minutes their content was viewed in any given pay period.

If you cheat, you should get a zero. How is this controversial.

Since high school, the expectation is that you show your work. I remember my high school calculus teacher didn't even LOOK at the final answer - only the work.

The nice thing was that if you made a trivial mistake, like adding 2 + 2 = 5, you got 95% of the credit. It worked out to be massively beneficial for students.

The same thing continued in programming classes. We wrote our programs on paper. The teacher didn't compile anything. They didn't care much if you missed a semicolon, or called a library function by a wrong name. They cared if the overall structure and algorithms were correct. It was all analyzed statically.

Anecdotally I’ve felt this shift over the past few years. I am 33 and have always been a huge proponent of personal growth, change, pushing yourself to be better. In the past few years Ive felt the opposite urge, an urge to accept myself, flaws and all, as the hand I’ve been dealt and I must merely play that hand, not focus so much on what-ifs, etc. Perhaps this is my brain solidifying.

3Dfx was not the inventor of the GPU. There’s a long history of GPU development for corporate applications.

The iPhone wasn’t the first mobile phone. Early mobile phones were very expensive and targeted as businesses who wanted their executives in touch

You’re still thinking from a consumer-centric view. Zoom out and those consumer companies were not the first to develop the products. You didn't even think about the actual originators of those types of products because you don’t see them as a consumer.

We're speaking to different things.

Safety doesn't mean you're a provider. It means you are safe to be authentic with. Safe to share truth with.

That safety takes many forms.

You cannot have depth without that safety. It is physical, it is also emotional and intellectual.

For instance, without safety a partner would never join you on many interesting experiences. If you want those experiences, they need to be able to trust you.

Now extend that idea of safety to a broad society context, and that is approaching what I was speaking to.

There is a difference between telling Claude to do something and actually doing it, and writing about it. The fact that this has 199 points as of writing this comments means people want to read about the results. You will probably be quite unhappy to learn that Claude write the majority of the blogpost as well -

"Hey claude read my previous posts and this script and generate a new blog post about this temp control stuff. Generate whatever plots you want. Here's how you can access my influxdb with the data. Here's how you can ssh into the Pi to get the exact running scripts. Ok here's my wordpress token - upload it and the pictures. Oh it looks like your .md to wordpress failed really bad, read a previous post to find out how to format stuff. Oh the tables are still not right, try again." <-- literally what I spent an hour doing last night and refining.

As the authors mentioned, ~30 years is the age many people have kids, and it is already well known that female brain changes after giving birth, for example. The authors didn't research if being a parent can explain a part of the difference (and also if parent brains are any different than childless people brains).

I'm personally curious about this: I'm slightly above 30, I observed significant changes in my behavior recently... and I became a parent this year.

I beg to differ. Tactical use of a scientific or graphing calculator can absolutely replace large parts of the thinking process. If you're testing for the ability to solve differential equations, a powerful enough calculator can trivialize it, so they aren't allowed in calculus exams. A 10-digit calculator cannot trivialize calculus, so they are allowed. That's the distinction. LLMs operate at the maximum level of "helpfulness" and there's no good way to dial them back.

> with very little gains in raster performance this decade.

I have a flagship 7-8 year old GPU in one machine and a mid-level modern GPU in another.

It’s flat out wrong to claim “very little gains” during this time. The difference between those two GPUs is huge in games. The modern GPU also does it with far less power and noise.

I can’t understand this HN mentality that modern hardware isn’t fast or that we’re not seeing gains.

I dunno, there's definitely stuff that's convenience related, sure, and then there's stuff that's less so. Things like MediatR, Dapper, Serilog, Refit are all pretty common in .NET projects. There's usually always some library for generating PDFs for reporting purposes etc. The ecosystem of NuGet packages is pretty large. It's definitely not all just Microsoft dependencies, nor is that usually how developers in the ecosystem think in my experience.

> you would expect that the reputation of the bad credentials would go down and the good credentials would go up.

We should expect this if employers can efficiently and objectively evaluate a candidate's skills without relying on credentials. When they're unable to, we should worry about this information asymmetry leading to a "market for lemons" [0]. I found an article [1] about how this could play out:

> This scenario leads to a clear case of information asymmetry since only the graduate knows whether their degree reflects real proficiency, while employers have no reliable way to verify this. This mirrors the classic “Market for Lemons” concept introduced by economist George Akerlof in 1970, where the presence of low-quality goods (or in this case, under-skilled graduates) drives down the perceived value of all goods, due to a lack of trustworthy signals.

They are increasingly unstable, hence why I pondered about some enthropic limit the higher up it goes in the enthropy ladder.

Atoms are quite stable, even though they also suffer from quantum decay; then molecules can be stable but are less stable than atoms; up the ladder to biochemistry it starts to become more unstable the more complex it gets; so on and so forth.

Stable societies might be something that humans haven't achieved yet but somewhere in the Universe some other lifeform might, each rung of the ladder will filter out the most unstable versions of it, coalescing into the emergence of the more stable versions of it. Advanced technology is very unstable for us, requiring constant maintenance by intelligent humans.

Of course, it's just food for thought :)
