I wouldn't be surprised if the video models were vastly undertrained compared to our text models. There's probably millions of hours of video we haven't used to train the video models yet.

Still seems like early days on this tech. We're nowhere near the limits.

Just a year ago we could only create the distorted video of Will Smith eating spaghetti. A year from now this is going to be even more flawless.

I agree that they can get the data through other means. Not so sure about

> There are so many different players who have access to most or all of the data it would hard to prove it came any one source at all.

Because a prosecutor can obtain copies of all emails talking about this, they can examine your bank accounts for payments from data brokers, they can require legal to give them copies of any contracts, they can look at audit logs from the production database and airlines aren't Evil Inc -- stuff will inevitably leak and get out. You can't cover yourself that well as a CEO looking to make a quick buck...

Blockchain is capitalism at its finest. It rewards risk because risk-taking drives innovation, builds businesses, and creates jobs. Banks fund that because it grows the economy, and they make money on the upside. So yeah, risk-takers get the incentives, and thanks to those incentives they end up siding with the banks and preaching the system they're now part of.

Imagine the cost if JPMorgan had to run all that compute themselves: power, hardware, cooling, security, redundancy. It'd be massive.

So what did the mysterious man at the top of the pyramid do? He got the public to do it. By distributing the computational load and offering tokens as rewards, he turned millions of people into the infrastructure. They pay for the hardware, run the nodes, and keep the system alive for free.

Satoshi knew exactly what they were doing and why. That kind of precision doesn't come from guesswork. So chances are we'll never know who they are.

Same goes for the economist who inspired by Milton Friedman turned the idea of future-income-based education into the student loan system we have today.

Some ideas don't want a face.

As far as I can tell, the AGI fantasy is the usual counter-argument to this. "AI is going to make everything 10x more productive", "AI is going to invent new efficient energy for us", etc. And it's always "just around the corner", to make the problems of the current generation of LLMs seem (soon) irrelevant

I don't see anything, anything at all, that would make a significant percentage of Cursor users consider the switch.

They can try to market grab with low %, but will find themselves in the boat as Cursor and eventually be forced to raise their prices. Except their market grab will be significantly less effective because they're not a stand-out product. Cursor was.

I would expect any change to an optimized workflow (developing own well understood project) to initially be slower. What I'd like to see is how these same developers do 6 months or a year from now after using AI has become the natural workflow on these same projects. The article mentions that these results don't extrapolate to other devs, but it's important to note that it may not extrapolate over time to these same devs.

I myself am just getting started and I can see how so many things can be scripted with AI that would be very difficult to (semi-)automate without. You gotta ask yourself "Is it worth the time?"[0]

> -all existing investors and vested employee/equity holders are paid out;

But the statement from Cognition was:

> 100% of Windsurf employees will participate financially in this deal > 100% of Windsurf employees will have vesting cliffs waived for their work to date > 100% of Windsurf employees will receive fully accelerated vesting for their work to date

The details matter. "vesting cliffs waived" meaning what? Windsurf shares exchanged for Cognition shares? at what ratio?

"Participate financially" means what exactly? They could all get a coupon for a free doughnut, and that statement would be true.

I'm not saying the employees are getting nothing, or even a raw deal. I'm saying we have no idea if the deal is good for them, without details.

> theoretically the remaining company could pay accelerate vesting, then pay out the cash to their remaining employees, and then shut down, to give everyone the same exit as an acquisition, or better.

unlikely that will happen. More likely the investors and VCs will take the lion's share of the $2.5B, that is what they do. That is why they exist. And they'll distribute as thin a slice as possible to the employees.

The math seems to suggest R=a, or simply the spin in terms of length. It's certainly an oversimplification, as the answer will depend on the choice of metric.

Here's the best resources I've been able to find on the question. Roy Kerr himself responded to the Quora question:

> There is no Newtonian singularity at the Center of the earth and there is no singularity inside a rotating black hole. The ring singularity is imaginary. It only exists in my solution because it contains no actual matter. When a star collapses into a black hole it keeps shrinking until the centrifugal force stabilizes it. The event shell forms between the star and the outside. In 57 years no one has actually proved that a singularity forms inside, and that includes Penrose. instead, he proved that there is a light ray of finite affine length. This follows from the “hairy ball theorem”.

The stack overflow answer seems to describe the problem in terms I can better understand:

> It seems unlikely to me that you're going to be able to formulate a notion of diameter that makes sense here. Putting aside all questions of the metric's misbehavior at the ring singularity, there is the question of what spacelike path you want to integrate along. For the notion of a diameter to make sense, there would have to be some preferred path. Outside the horizon of a Schwarzschild black hole, we have a preferred stationary observer at any given point, and therefore there is a preferred radial direction that is orthogonal to that observer's world-line. But this doesn't work here.

Anyone could have acquired this data the time, it was all either free or cheap. Like I said, my business was specialized data infrastructure (e.g. storage engines and analytical parallel processing), we just used these data sources for testing and demos because "free or cheap".

I also have a lot of experience with privileged first-party data but that is governed by a different set of rules and is often regulated. You have to be much more circumspect about how you use it.

Even though it might be convenient to e.g. slurp telemetry off a mobile carrier's backbone, what you eventually realize is the inability to do this isn't a real limitation and in some ways is a blessing in disguise.

> I don't think you give people enough credit. There have been dissidents in totalitarian regimes the world over, even when the punishment was death or being sent to a labour camp.

You probably know very little about totalitarian regimes? The thing is that they usually have a rather weak legal system, governed by the principles of lawlessness. This creates strong incentives for dissident activity:

- You won't be caught, because the police are interested in breaking their own laws, and not in finding criminals - If you are caught, there is a chance to buy your way out, because the police are more interested in receiving bribes than in jailing a dissident who has violated something unclear - Even if you are completely law-abiding, you can still be detained as a dissident, because they urgently need to catch a dissident today - You can't be completely law-abiding citizen, no one can, laws doesn't supposed to be workable. And if you break a bunch of laws just because you breathe, it's easy enough for you to break just another one - And even if you obey all the laws you can, what awaits you? A miserable, half-starved life that can be cut short at any moment for any reason - You don't receive social stigma and disapproval, because the majority of society clearly does not approve of the persecution of dissidents

The point is that severe punishments, including the death penalty, are used under totalitarianism precisely because of impotence in the fight against dissidents.

But we are talking about completely different regimes. Regimes with laws that work. Regimes with extremely efficient bureaucracy. Regimes where people have very much to lose and where they clearly know what they need to do to avoid losing it. And regimes with a system of totalitarian surveillance of all citizens. People won't need to be executed. Just a small fine EVERY time - and very quickly there will be no one left.

> but I think many people would see it as the start of China-like censorship.

The start has already begun, and as I see it, China is a children's party with tea and custard cakes compared to what awaits us.

This is exciting. So this is using unified memory of CUDA? I wonder how well that works. Is the behavior of the unified memory in CUDA actually the same as for Apple silicon? For Apple silicon, as I understand, the memory is anyway shared between GPU and CPU. But for CUDA, this is not the case. So when you have some tensor on CPU, how will it end up on GPU then? This needs a copy somehow. Or is this all hidden by CUDA?

This is the latest in a very honourable tradition. My first encounter with it was with Martin Richards's BCPL system in 1972. The compiler generated a hypothetical ISA called OCODE, from which backends generated pretty good native code for Titan-2 and System/360, among others. One of those backends generated INTCODE, which was an extremely reduced ISA, for which an interpreter could be easily written (I wrote one in Fortran). Richards also provided the BCPL compiler and runtime library in INTCODE, so you could quickly have BCPL running interpretively. Then you could use this interpretive version to bootstrap a native-code backend implementation. Put this all together, and you now have a very easy compiler port.

Wirth's Pascal-P compiler of 1974(?) used the same idea, also in aid of a highly portable compiler. I have never been able to find out whether this was an independent invention, or whether Wirth was influenced by Richards's work.

Of course, the JVM and CLR are descendents of this, but they build a very complex structure on the basic idea. Writing an implementation of one of these virtual machines is not for the faint of heart.

So I think Bedrock can be very useful as a compiler target, if nothing else. However, I must agree with some of the other commenters that the 64KiB address space makes it very much of a niche tool. Come up with a 32-bit variant that's not much more complicated, and I think you have a winner.

the govs of the left shifting countries in EU (Norway, Denmark, Iceland) played an active role in nipping private energy monopolies in the bud. (Where did Spain err in comparison?) Their policies probably would be regarded as communist in the US though. I tend to call it "communitarian" rather than "communist", but I might be too lazy to argue that distinction :(

Abstract >Traditional corporatist mechanisms in the Nordic countries are increasingly challenged by professionals such as lobbyists, a development that has consequences for the processes and forms of political communication. Populist polit­ical parties have increased their media presence and political influence, whereas the news media have lost readers, viewers, listeners, and advertisers.

I worked as a contractor at Lotus for about a year, back in 1987. My client/friend told me a story about Kapor that has stuck with me, although it turned out that she was an utterly unreliable witness... so take this with a grain of salt. She was Lotus employee #70, though, so maybe it's true.

Kapor found himself in an elevator with another employee sometime after he had handed over the reins to Jim Manzi. The other employee, who apparently didn't recognize Kapor, was dressed in a full three-piece suit. "That's when Kapor decided to leave," my erstwhile friend told me. "He said, I started Lotus because I wanted a company where I could wear Hawaiian shirts and sandals. I didn't want to work somewhere where I had to wear a suit." But that's what Lotus had become, so it was time to go.

We never met, but I have always admired the guy.

ping and mtr only test one thing. I have saws, drills, routers (lol), planes, screwdrivers, hammers and more in my workshop. To be fair a drill driver and a hammer get a lot of jobs done! However, I will get the impact driver out or a fret saw with a very fine blade as the job requires.

The article here is about a loss of DNS service and proves it with ping. That is wrong and you know it. Diagnosing the fault should involve ping but that is not how you conclusively prove DNS is not working.

To be honest you cannot conclusively prove anything in this game but you can at least explore the problem space effectively from your perspective with whatever you have access to. I happen to have a RIPE ATLAS probe at work with a gigantic amount of credit, so I could probably get that system to test Cluodflare DNS from a lot of locations.

If you present to a doctor with some mild but alarming chest pains, I'd hope they wouldn't just look at you and prescribe a course of leeches. A stethoscope is a good start (ICMP) but an ECG (dig) is better. That analogy might need some work 8)

FSR 3.1 has been supported for over a year. https://www.reddit.com/r/SteamDeck/comments/1dq8ztk/fsr_31_f...

GE-Proton is easy to add and added FSR4 support in the recent 10.9 release, https://www.gamingonlinux.com/2025/07/ge-proton-10-9-release...

There are mods for if you have a game that alas uses an icky, proprietary framegen, to use FSR instead. https://www.resetera.com/threads/framegen-mod-available-for-...

Steam's performance hub shows what frame gen is running and how many frames it's generating. Now on the rest of Linux clients too (mangohud is also very popular). https://www.gamingonlinux.com/2025/06/steam-gets-a-new-steam...

> This feature which currently has a lot of bad press(rightly so) really is perfect for Handheld gaming and Valve should be staying on top with the updates more.

There's no company in the history of Linux that has done 1/20th as much to "stay on top with the updates" to Linux.

Definitely deeply considering flipping the bozo bit here! Lot of dad tramboning over things that work, well.

It’s not just GLP-1s.

Look at CAR-T therapies (your cells are reprogrammed to fight your cancer). Insured patients got access in the US long before, and to a broader degree, than national healthcare systems.

Today, CAR-T utilization in cancers like lymphoma are double those of Europe in many cases. Interestingly the UK is one of the highest in Europe (despite the controversy over cancer drug spending).

While true that the US has uninsured and not all insurance is equal, suffice to say you stand a better chance to get access to new technologies in the US than most countries.

That still isn’t logical. If Apple is the only thing holding great web apps back, then why don’t companies just spend money on a web app + iOS app instead of also creating an Android app?

Even if they did an iOS app + web app for Android, if it were just Apple, they would still save money on Android Play Store fees.

But the truth is that browsers aren’t good enough on Android even though it is “open” [sic] and most Android phones sold are so underpowered that you have to make a native app to get any type of responsiveness.

Having the Firefox engine or Chrome engine isn’t going to make it any better. If the alternate browsers that are on the Mac are any indication from both companies - they are going to be slower and less battery efficient.

> The short of it is that your "making the AI want what you want" is called extrinsic internalization. It is highly problematic. It is not surprising that a roomful of CS technocratic researchers (beholden to SV funding) would make this sort of lay psychology mistake--a smuggled premise. It is bad science, and irrational.

Problematic or not, the technical term is "reward function", and you don't get to not have one in an AI, not even when it's e.g. AlphaGo. The hard part is specifying the reward function to match what you actually want, otherwise you get Goodhart's Law.

Talking about this in psych terms is a "wet pavements cause rain" error.

> If you want to lead with ad hominems then I studied EECS at Berkeley then for my PhD at Princeton, so I have every right to criticize the more prominent leaders of entire field for being philosophically blinkered.

The right to, sure. I'm not stopping you from doing it. I'm saying you're making a foundational error in your criticism.

> In fact a cursory check shows CS AI papers written by dissenting scientists who are very much against the alignment framework.

Naturally. Dissent is normal.

As for details of which matters and how hard they might be: inner alignment, outer alignment, Goodharting, specification gaming, principal-agent issues, anything Yudkowsky has ever said about it being impossible because we only get one chance and we're bad at this, etc.

But your dismissal, as you wrote it in this thread, is as shallow as you call mine.

(Not that I expect you to read this given the other comment, but if you name a scifi setting famously anti-AI, from whence the term "Butlerian Jihad" entered our culture, you should expect to be called out on that. And TBH your replacement wasn't any good either: not only is Measure Of A Man more about the question "Is this AI a person at all?", but fictional references are not evidence of anything beyond the culture in which they were created).

The original submission to HN stated that it was from Amazon / AWS in the title of the submission, however that has since been edited by a moderator to match the title of the blogpost, which does not mention Amazon / AWS.

To be clear, we have no intent to hide that Kiro is from Amazon / AWS, that's why you'll see Matt Garman, for example, posting about Kiro: https://www.linkedin.com/feed/update/urn:li:activity:7350558...

However, the long term goal is for Kiro to have it's own unique identity outside of AWS, backed by Amazon / AWS, but more friendly to folks who aren't all in on AWS. I'll admit that AWS hasn't been known in recent years for having the best new user or best developer experience. Kiro is making a fresh start from an outsider perspective of what's possible, not just what's the AWS tradition. So, for example, you can use Kiro without ever having an AWS account. That makes it somewhat unique, and we aim to keep it that way for now.

It used to be 30/month for me. I was not renting their modem and got charged more for it.

If starlink ever gets more capacity, I'll probably switch. Right now I think the only way to get gigabit down on starlink is with four or five accounts and manually bonding the dishes together. As soon as that obstacle goes away, Comcast will have competition in my area and I intend take advantage of that.

Nǐ hăo, xìe xìe Yuntian! I read the readme and paper but haven’t played around much yet. I find this fascinating and I don’t care much about poor “experience” because intuitively I feel this idea couldn’t produce something as reliable and flexible as a real OS anyway. I see you talked about inability to install new software and my reaction was “well obviously”, because surely it will be at least as limited as the training data, while a real OS provides lots of software of great complexity which is seldom used.

Could you talk about your hopes for the future on this project? What are your thoughts on having a more simplified interface which could combine inputs in a more abstract way, or are you only interested in simulating a traditional OS?

Thanks again.

PS the waiting time while firefox “loads” made me laugh. I presume this is also simulated.

If you have a demonstrated network/connectivity problem to an endpoint that provides DNS, then DNS is down (or at the very least degraded) for you. If a functionality of layer 3 is not working, should we expect layer 4 to work, and keep looking into aspects of layer 4 and/or layer 7, or would it make more sense to keep troubleshooting the layer 3 issue?? Any entry level NOC Technician would know at this point that doing digs/queries to the endpoint would not necessarily be meaningful when we have an underlying connectivity/network problem that is the likeliest main contributor to the issue.
