Yes, China is about the same size as the US, but a route from Beijing to Kashgar is 23k feet up and 21 k feet down. A route from Washington DC to Los Angeles is about the same distance, but has 77k feet up and 77k feet down. A lot more elevation to work through. Much of the east side of that map is relatively flat. And there are bottlenecks getting to the west side, as there would be in the US, but the US has a lot more relative population on the west side than in China.

I'm sure that rail wins over flights in terms of efficiency for passenger miles traveled. However, you often have to travel more miles to get to your destination. A direct flight can save a whole lot of time. Flights are much faster, although security theater adds a lot of time[1]; but for longer routes, or routes with many stops or connections for rail, the single segment operation of a flight starts to win.

Also, China has the advantage of authoritarianism which allows it to more easily get right of way that's well aligned for HSR. While it was once easy to get land for railroads, when there were active land grants, now you'd need to do a lot of work to get well aligned land to add a rail line; where they're still active, existing rail right of ways through developed areas are fine enough for slower service, but expanding the right of way to better align the tracks is a lot of work. In theory, you could eminent domain, but that process is long and expensive.

[1] In a world where you think it's possible to have government intervene to expand passenger rail in the US, it's equally possible to have government intervene to streamline the security theater in flights; or they might add the same security theater to passenger rail.

We have a way to tie identity to agent/requests. It's called IP address. Every IP address has a provider's identity, and most providers can further specify an individual or business.

It doesn't help. Do you know why it doesn't help? It doesn't help because AI companies just pay people to borrow your identity. Somewhere between $2 and $250 per month to borrow your internet identity - the former for running a program in the background on your computer and the latter for getting an internet contract in your name. Or you can pay developers of free mobile games to put your code in their game, and the user doesn't know about it, and it's not even illegal.

All that will happen if you tighten identity further is that these measures will go further, e.g. farms of real devices with robots giving touch inputs and cameras running OCR. Meanwhile you'll make it more annoying for everyone to use the internet until they quit.

You know what other effect it has? Only big players will be able to afford the workaround measures. Google will have no problem deploying an army of robots with phones (or just faking it since they own the signing keys) meanwhile you just banned every non-Google non-Apple phone from your website, forcing centralisation and monopoly on everyone.

And for what? Saving 3 requests per second of server load?
Open source alternative to Lovable, Bolt and v0

Hello guys i built Free & Open Source alternative to Lovable, Bolt & V0.

grills: https://grills.dev

github: https://github.com/grillsdev/grills

It is still in a very early stage. Currently preview is only supported in Desktop Chrome. Try it out, raise issues, and i’ll fix them. Every bit of feedback is appreciated I will keep improving it. Let’s make this one of the biggest open source project

This is completely right from a product point of view, which is Carmack's argument.

But I have wondered why one of these companies with billions of dollars to burn hasn't tried to create something new as a strategic initiative. Yes, there wouldn't be any ROI for years, and yes, the first several products on the platform would probably be better off on something more traditional.

But the long term value could potentially be astronomical.

Just another case of quarterly-report-driven decision making, I suppose. Sigh.

Qwen3-Coder-480B hosted by Cerebras is $2/Mtok (both input and output) through OpenRouter.

OpenRouter claims Cerebras is providing at least 2000 tokens per second, which would be around 10x as fast, and the feedback I'm seeing from independent benchmarks indicates that Qwen3-Coder-480B is a better model.

Locked down meaning the storage devices are encrypted and decrypted on-the-fly via the SoC/CPU using a key programmed into the Fuses/OTP (this is usually per device keys), bootrom/loader requiring signed firmware images, limited exposure of external interfaces (attack surface) - from my memory even the Uart interface attached to the SoC was disabled very early on in the boot loader, exposing only one or two messages. I would not expect that ram is encrypted - I cannot think of a single time I have seen that implemented in a device. Maybe it’s time to dig that board out of storage and poke at it a bit more invasively, my understanding is they are not very robust when faced with fault injection :>

Isn't that somewhat debatable? Originally they were aiming at much more (chromebook OS for example) but seems like they settled for Google Home only as their scope.

Still a very interesting project, but that feels like a similar story, for limited use cases (a smart thermostat/speaker with specific hardware) it works, but for wider use cases with heterogeneus hardware and complex interfaces (actual screen, peripherals) it didn't work.

> all this talk will sound as dumb as stating "MS Word spell checker will replace writers" or "Photoshop will replace designers".

You cannot use just a spell checker to write a book (no matter how bad) or photoshop (non-AI) plugins to automatically create meaningful artwork, replacing human intervention.

Business people "up the ladder" are already threatening with reducing the workforce and firing people because they can (allegedly) be replaced by AI. No writer was ever threatened by a spellchecker.

Hollywood studio execs are putting pressure on writers, and now they can leverage AI as yet another tool against them.

I wonder how many CPU cycles are spent because of AI companies scraping content. This factor isn't usually considered when estimating “environmental impact of AI.” What’s the overhead of this on top of inference and training?

To be fair, an accurate measurement would need to consider how many of those CPU cycles would be spent by the human user who is driving the bot. From that perspective, maybe the scrapers can “make up for it” by crawling efficiently, i.e. avoid loading tracker scripts, images, etc unless necessary to solve the query. This way they’ll still burn CPU cycles but at least it’ll be less cycles than a human user with a headful browser instance.

The developer is supposed to check and verify the code that an LLM creates. Ask for smaller requests in the prompts so you don't get too much code. Unit tests are verified and run by the developer. I don't know what he means by an LLM runs all the tests and gives green. It can fake running tests. I always the tests myself, whether they were created by an LLM or not.

It has been my experience that those that complained the loudest about CSS, expected to know it without actually studying or learning it. They already know a "real" language, so why should they have to study a "toy" styling language.

When it comes down to it, making a great looking and maintainable page is just as much work and planning as building a good backend codebase. Neither one just happens.

Not all reals are expressible: to be expressible is to have a finite representation in some language. Definable numbers [1] are that (countably infinite) subset of the reals which can be expressed individually. Almost all reals are not definable and therefore cannot be individually named.

It's unclear to me how much L&O Holdings actually does to bring the two remaining Sigs together (Sig Germany is defunct as of 2020). They do not sell each others products, do development cooperatively, produce cooperatively, etc as far as I've seen. Sig Switzerland issued that foot-in-mouth memo backing the P320, so there's clearly something happening between the two, but I think presenting them as separate is more accurate than claiming they have a close relationship because the same holdco owns them both.

The "fix" only works on models with a manual safety and only when the safety is engaged. If you release the safety, like many people tell you (as a matter of subjective opinion) that you should while conceal carrying, it won't do dick. Or even just release the safety because you're going to fire soon but not sure when -- same deal -- same flaw and it could go off without pulling the trigger.

So the fix is as good as commercially useless, although better than nothing, the market is basically the guy who wants to be able to take it to the range and then always have it downrange while the safety is off.

> In his announcement on Friday, Rubio said: "Before the PLO and PA can be considered partners for peace, they must consistently repudiate terrorism - including the October 7 massacre - and end incitement to terrorism in education, as required by U.S. law and as promised by the PLO."

I'm assuming that the Saudi Arabian congregation got visas. State-sponsored terrorism is OK if it's 9/11 or the killing of Jamal Khashoggi, but not in this case. The US is truly a vassal state for Israel and Saudi Arabia.

I'm not a "real coder" either, but it sounds like the "No True Scotsman" trap when people say, “AI can’t be a real coder,” and then redefine “real coder” to mean something AI can’t currently do (like full autonomy or deep architectural reasoning). This makes the claim unfalsifiable and ignores the fact that AI already performs several coding tasks effectively. Yeah, I get it, context handling, long-horizon planning, and intent inference all stink, but the tools are all 'real' to me.

This seems to assign a cause without merit other than AI is the buzzword of the day.

Receptionist jobs down.. this has been the case for a while, and does include some AI, but AVR and general speech recognition and matching has gotten pretty good for a while, I'd say AI is half a step back.

Translators, maybe AI, but again, speech recognition in general is pretty good and not strictly an AI thing... but I'll give that one credit.

Software Engineers, maybe it's more about the (I don't even know the right current FAANG acronym anymore) companies that have laid off tens of thousands in the past few years and largely replaced (if at all) them with either contract or h1b workers? Only to grow short term margins on already profitable companies.

Pretty sure that's false: I remember seeing the recent commit that made Grok misbehave.

Go to Bluesky and count far left posts. The result will be similar, because political bubbles form by themselves.

There's a reason I included that "even", because indeed NL is not cheap. However if you're not in SV or NYC, you're also not making the ludicrous half-a-million figures that people often talk about as well. Myself having lived in NYC, I can tell you right now QoL is dramatically higher in NL even if I'm earning a lot less cash. Also, it definitely is cheaper than those cities, even if you're in Amsterdam (and cities like Utrecht or Den Haag are a lot cheaper than Amsterdam too).

Around the 50-60k Euro mark is a VERY decent and comfortable living in the Netherlands and you'll be hard pressed to find companies not paying that much for medior roles, yet alone senior ones. Plus you have the bigger companies like Adyen, Booking, ASML etc. plus remote US companies that pay ~100-125k for Medior+ talent (I know this as I literally today, a mere 4 hours ago got an offer letter from one of the mentioned companies as a SWE II). The taxes only really start hurting in the 70k-90k region, but since it's progressively taxed it's still not the end of the world. Also if you work for one of the aforementioned big boys then you're probably going to be in the party bracket (literally what it's called :p) where the sting is lessened, stupidly enough.

Remember, average salary in NL is around 40k-45k EUR. If anyone above a medior level manages to work at a tech-adjacent company as is getting paid less than that, it's time to move jobs because the market has shifted up massively as of late in terms of wages, at least anecdotally from what I can see.

And most importantly, money isn't everything which is so often missed in these discussions talking about EU vs US comp. Most importantly of all is that I never have to worry about healthcare costs should anything happen to me or my loved ones that don't have the privilege of being sponsored by a megacorp, and very importantly I have job security and a permanent contract that makes it damned hard to get rid of me.

Now things aren't perfect here obviously, train costs are astronomical, the tax brackets are absurd (the aforementioned party bracket being an absolute farce), the healthcare system while great can be very annoying to navigate alone, and indeed rent in the private sector and housing costs in general is completely detached from reality... But compared to anywhere in the US I've ever lived, especially if we zoom out a bit and look at it from a lens of someone not in tech and not making FAANG-level money? I'll take Utrecht 100 times out of 10, thank you very much.

Because the value of IP is stored in cultural zeitgeist. People don't want to go to "A mouses fantasy location" they want to go to Disneyland.

Convincing people to give a shit about your IP is a totally different issue to producing it, in my opinion. There are already countless talented artists a big producer could hire to make them new IPs but it is still incredibly rare for a new IP to take off.

Art keeps getting cheaper and easier to make yet as a society we are addicted to remakes and expanded universes, new seasons of shows that ended a decade ago etc.

This is dangerously oversimplified. It takes no account of source files with multiple tracks, so you'll probably end up accidentally throwing some away.

The "quality" slider implies that if you move it to the right, you'll get more quality. But higher numbers of the crf value are lower quality, not higher.

The resize function takes no account of the original aspect ratio of the source video, so you'll probably squash things.

Audio extraction ignores whatever the source codec is, missing the opportunity of extracting the source codec without recompressing. Additionally the built-in "aac" codec is very low quality and should not be used. ("libflac" is probably a better choice than "flac", too.)

> I'm talking about something with an ARM CPU,

Why? There is no evidence that ARM is the only power efficient CPU. i5, i3 and n100 are all power efficient.

> no video, no audio

Why? Disable onboard video if you care that much.

> lots of memory (or SODIMM slot) and 10+ SATA ports This eats power, conflicting with the rest of your requests.

> Sure, anyone can buy a self-powered USB3 hub and add 7 external HDDs to a raspbery, but that level of performance is really really low, not to mention the USB random disconnects. And no, port replicators aren't much better.

No, that's not what you do for a power efficient NAS. You build an i3, i5 or n100, turn off all unneeded peripherals, and configure bios as needed to your level of desired power consumption. under 10W is achievable.

I'd love a truly new OS, but I just don’t know what it would look like at this point? "New OS" ideas tend to converge on the same trunk.

Building a hobby OS taught me how little is just "software". The CPU sets the rules. Page tables exist because the MMU says so. Syscalls are privilege flips. Task switches are register loads and TLB churn. Drivers are interrupt choreography. The OS to me is just policy wrapped around fixed machinery.

To be more specific, if we assume good faith upon our fine congresspeople to craft this well... ok yeah, well for hypothetical case I'll continue...

What legal teeth I would advocate would be targeted to crawlers (a subset of bot) and not include your usage. It would mandate that Big Corp crawlers (for search indexing, AI data harvesting, etc.) be registered and identify themselves in their requests. This would allow serverside tools to efficiently reject them. Failure to comply would result in fines large enough to change behavior.

Now that I write that out, if such a thing were to come to pass, and it was well received, I do worry that congress would foam at the mouth to expand it to bots more generally, Microsoft-Uncertified-Devices, etc.

That's not correct. Sig Sauer USA's VP of Engineering Adrian Thomele was originally an Sig Sauer AG employee, who owned a company that was acquired by Sig Sauer AG. There are other examples of engineering management propagating from the German/Swiss entities and sharing IP between one another. Secondly, Sig Swiss AG recently announced that they would be manufacturing the P320. The German entity was shuddered to decrease manufacturing costs and effectively offshore to Sig Sauer USA, who is now also offshoring more manufacturing operations to India. I think there is much less independence than you might think between the entities.

https://pure.md is exactly what you're looking for.

But stripping complex formats like html & pdf down to simple markdown is a hard problem. It's nearly impossible to infer what the rendered page looks like by looking at the raw html / pdf code. https://github.com/mozilla/readability helps but it often breaks down over unconventional div structures. I heard the state of the art solution is using multimodal LLM OCR to really look at the rendered page and rewrite the thing in markdown.

Which makes me wonder: how did OpenAI make their model read pdf, docx and images at all?

I can't imagine a realistic scenario where I've taken the slack out of a trigger and don't have the intent to continue pulling through to the break.

Modern military doctrine says that you shouldn't even pull the weapon from the holster if you don't have the intent to fire. Even if you're not quite willing to implement that (eg for LE), you shouldn't be touching/pulling the trigger without an extremely firm intent to fire.

I was at ReactSummit this June and spoke with some folks from Vercel about Next.js and RSC support outside of the framework. I really wanted to try all the cool stuff but couldn’t afford to migrate my massive apps to Next.js. The conclusion was clear: it’s difficult to start using RSC without a framework.

“Hold my ,” I said to myself, and started exploring.

The real big brain move is to be your own competitor, so you extract value from customers either way. If they don't switch, you get to extract value via planned obsolescence and plain old extortion. If they do switch to avoid the extortion, you at least get to keep the price of their new NAS, and you weren't likely to get the extortion money anyway.

America has thousands of food brands but they're all owned by about 6 companies.

Quantum mechanics actually contains measurable real numbers (well.. complex numbers). Amplitudes are postulated to be infinitely precise, and rounding them has a tendency to introduce pretty serious consequences like FTL communication.

For example, in fault tolerant quantum computing, rotations are synthesized using sequences of 45 degree rotations around the X, Y, and Z axes. The matrices that describe those 45 degree rotations contain rational and irrational numbers (in particular: sqrt(2)). If those irrational numbers are actually truncated, this would have observable consequences. You'd need a sufficiently large quantum computer running for sufficiently long to do sufficiently accurate tomography of sequences of those rotations in order to resolve the truncation, and to be frank some of those "sufficientlies" would be very impractical to achieve especially if the truncation was small (and woe unto you if adding more qubits somehow reduces the amount of truncation!), but in principle it'd be possible.

Observed on a production-fused A16 Bionic devices (e.g., iPhone 14 Pro Max),the internal debug pathways activating under stock iOS (debug = 0x0, dev-fused = 0). SecureROM, firmware, and co-processors all exhibit debug behavior without jailbreak, tampering, or provisioning profiles.

This violates Apple’s hardware trust model and exposes internal diagnostics meant for development silicon.

It's interesting that while Bourbaki had a large influence on modern mathematics, very few people read their books (at least among the people I know). In a sense, their project of producing a definitive exposition for a large part of mathematics has failed. I wonder whether it's because different branches of mathematics have their unique personalities, and therefore the attempt to provide a unified point of view are bound to fail.

He's acting like their VR UX is top notch when it's as bad as it gets. Just yesterday I dusted off my Meta Quest 2 to play a bit, and spent around an hour trying to pair up my left controller to the helmet after replacing the battery.

You can't do it without going through their fucking app, that asks for every permissions under the sun, including GPS positioning for some reason. After finally getting this app working and pairing it with my headset, I could finally realize the controller was just dead and their was nothing to do.

Yes, Replicache works beautifully on our mobile/native targets.

The constructor allows you to pass in any arbitrary KVStore provider, and we happen to use op-sqlite as its performance is exceptional.

There is no "different data layer" per se, just a different storage mechanism.

Replicache also holds a mem cache that is limited to ~50MB if I recall. Our use case is extremely data-heavy, so we might end up never migrating to Zero – who knows.

Perhaps I misunderstood your question, let me know if I can clarify further.
