> Assume FP64 units are ~2-4x bigger.

I'm pretty sure that's not a remotely fair assumption to make. We've seen architectures that can eg. do two FP32 operations or one FP64 operation with the same unit, with relatively low overhead compared to a pure FP32 architecture. That's pretty much how all integer math units work, and it's not hard to pull off for floating point. FP64 units don't have to be—and seldom have been—implemented as massive single-purpose blocks of otherwise-dark silicon.

When the real hardware design choice is between having a reasonable 2:1 or 4:1 FP32:FP64 ratio vs having no FP64 whatsoever and designing a completely different core layout for consumer vs pro, the small overhead of having some FP64 capability has clearly been deemed worthwhile by the GPU makers for many generations. It's only now that NVIDIA is so massive that we're seeing them do five different physical implementations of "Blackwell" architecture variants.

Actually climate is determined by cumulative CO2 emitted. The US and Europe have emitted far more than China ever has.

As of today, solar and batteries are the cheapest source of electricity. All the "poor countries in Asia and Africa", except the ones that have oil and gas, will leapfrog straight to renewables. It just makes good sense, unless your politicians are paid off by the fossil fuel lobby.

That seems like a really bad decision. Europe should reduce its ability to be controlled by the US. Yes the Trump admin is only one administration - but it has shown an interest in permanently ruling America. The risk is too great.

I do think there is validity to abandoning their current project. The person in the article who asks whether they would really need a manned fighter in the future is perhaps right given it may be 20 years before a new jet is in operation. But I feel like they should focus on an existing fighter like the Gripen and on drones instead of giving more money and control to America.

> is there an actual expectation of being able to tell the actual ethnicity/countries apart?

Facial structure, there are some obvious ones in ALS. But generally speaking, it's fashion that gives it away. I can spot a (relatively recent) Japanese immigrant from a hundred feet away by her clothes. It's a bit like if you see someone in Europe with a baseball cap, you can be almost certain they're American. Sandals with socks? German. Etc.

From the Conclusion:

> Does this mean that it is futile or meaningless to attempt to compose Elvish sentences? Well, no. [...] it is indeed possible to produce written Elvish that so far as anyone now can tell conforms grammatically and idiomatically to the exemplars and statements that Tolkien provided to a very high degree (for example, by relying only upon attested elements and derivational mechanisms, attested grammatical devices, and attested syntactic patterns that can reasonably be thought to belong to the same conceptual phase) — though I very much doubt that anyone will ever be able to do so quickly enough to use Elvish as a spoken language, for any but the most trivial sorts of declarative sentences.

I hate to be the one, but I haven't seen anyone else refer to them: how good are LLMs at following patterns of invented languages, in either direction (ie. inventing a translation from English to Sindarin and then, separately, translating the invented Sindarin back to English)? It's a usage where "hallucinations" are basically required, but also, the consistency of hallucinations has to be high.

Not the person you’re replying to but backing up what you’re saying - I read a lot of fiction for pleasure, I can say with some assurance whether I’ve read a certain fiction book, or, any book I’ve read for pure pleasure.
(Though as time goes on and I get older… I once started reading a book and about 15 pages in realized I had read it before )

As a hobby, I do a lot of wood working. Recently I was acquiring some books on wood finishes. I accidentally bought one book three times - not all at once but over a several year period. I realized this while trying to organize.

Mainly because they can have very similar / generic titles, and be by different authors. Since I’m using them as a reference, even if I know the author, I can’t always remember if I own this book by them or maybe I own this book with very similar title by a different author.

>There are zero credible studies that show that socialized healthcare increases costs and plenty of bankrupt Americans because of our broken healthcare system.

You can just look at the budgets of other countries and see that they pay dearly for their inferior healthcare where you will die waiting for care. At least in the US you can get taken care of and flush the debt down the toilet in bankruptcy.

>I went to the doctor because of chronic acid reflux. They charged me a copay. They couldn't help so they referred me to a gastro doc. The gastro charged me a copay (more because it was out of network—there's no in network gastro doctors in my city). I was given an upper endoscopy, but insurance only covered 10% of the cost of the procedure. I spent $500 on the medication I was prescribed afterwards.

I'm sorry to hear this. Chronic or routine issues are not what insurance is supposed to cover. Just as you cannot insure the motor oil or tires on your car and have it be worthwhile, you won't find insurance that is favorable for this under any system, no matter who is paying. The simple reason for this is mathematical and baked into the actual purpose of insurance. Insurance is supposed to protect against low probability, high cost events. The only way an insurer can stay in business, much less make a profit, is to charge more than they pay out. This applies to the government as well. Guess what happens when that gang gets permission to extract as much money as it takes to provide a modicum of healthcare? You get a lot of corruption and a shitty experience, and don't have the money to pay for anything better either.

>I have "good" insurance through my employer. If I didn't have insurance, I wouldn't have been able to get treated. The fantasy universe that you're describing is the one we live in: I have almost no choice, nothing is in network, and I spent $10k on healthcare on top of what's already taken out of my pay.

Your limit is $10k per year out of pocket no matter how much the treatment costs. Of course, the premiums technically come out of pocket too, just like taxes would in the case you dream of.

>Nobody in countries with socialized medicine has any of these problems.

You have no idea. I see stories all the time about people who wait for months to see a specialist in those utopian countries, and even die waiting to be seen "for free" (as 40% of their pay or more goes to fund the damn system). If you're in Canada, you may find your complaints about the system met with a recommendation for euthanasia, like that disabled veteran who made the news a couple of years ago. I suggest you do some research into these kinds of stories and temper your expectations...

It was luck that a viable non-graphics application like deep learning existed which was well-suited to the architecture NVIDIA already had on hand. I certainly don't mean to diminish the work NVIDIA did to build their CUDA ecosystem, but without the benefit of hindsight I think it would have been very plausible that GPU architectures would not have been amenable to any use cases that would end up dwarfing graphics itself. There are plenty of architectures in the history of computing which never found a killer application, let alone three or four.

Property rights themselves are a codification of a belief about nature, from a natural law perspective. There are other conceptions of property, of course, but of the ones that are relatively common, I think the least useful is the one that views property as whatever government says property is. Most people--well, most USians--think property has (and rights have) a meaning more fundamental than whatever the State arbitrarily grants. We note that animals defend scarce territory, that toddlers are upset when something they have is taken from them, that we distinguish jealousy regarding something we have and want to keep versus covetousness of something another has and we want to obtain.

Obviously the idea of copyright and patent as property rights didn't spring fully formed in the 1970s, but the entertainment and software industries during the 1970s and 1980s really drove the idea that copyright infringement is exactly the same thing as theft of something that someone actually has. The idea of copyright and patent in most law, including the US Constitution, are held as special, limited-term grants, not property rights.

That’s not true, the market loves pay per use, see ”cloud”. It outperforms subscriptions by a lot, it’s not ”one-off”.
And your example is not how companies building on top tend to charge, you either have your own infrastructure (key) or get charged at-cost + fees and service costs.

I don’t think Anthropic has any desire to be some B2C platform, they want high paying reliable customers (B2B, Enterprise).

> I've heard a lot about how beneficial it will be for large organizationally backed software products

It's a generic interface to anything, which allows people to communicate in their own way, and the LLM is pretty good at figuring it out. For non-technical people or customers who don't fully understand the product, it's going to be very helpful. RIP outsourced call centers, we won't miss you.

Manual search and navigation might be on the chopping block soon. Knowing how to navigate big software is often a bespoke skill. Now you can just talk to the computer and tell it what you're trying to do. Al down in the shoe dept doesn't have to figure out how to right click or what a context menu is. It's a fundamental UI change.

I think a lot of companies are going to get burnt on these things. Sure it is easy to one-shot something which looks close, but then you are responsible for releasing/maintaining/improving.

Not to mention that you'd need to integrate it with lots of other vibe-coded products. It can be great for some use cases for sure, though, but identifying them can be tricky, as big orgs are pretty terrible at formulating what they need clearly.

> Walmart + Amazon combined are only ~16% of the retail business.

of ALL RETAIL? That includes groceries! That's huge! Anyway, Amazon is >40% of e-commerce & Walmart is >10%. Together they control more than half of all online commerce. That's definitely monopolistic.

> It was not already a monopoly. […] shortly before your noted date of "regulation" those competitors held the majority market share

From Wikipedia: "AT&T controlled over 80% of the U.S. telephone system market by 1907 and Theodore Newton Vail rejoined the company as its President. Vail negotiated with competitors, charging them fees for connecting to AT&T's long-distance network. These practices led the Justice Department to attempt to breakup AT&T, but a settlement was reached through the Kingsbury Commitment on December 13, 1913. It brought federal oversight into AT&T and led its Bell System monopoly to become federally regulated."

They had an 80% market share pre-regulation. Yes, it was already a monopoly.

Yup. Any LLM recommendation for a product or service should be viewed with suspicion (no different than web search results or asking a commission-based human their opinion). Sponsored placements. Affiliate links. Etc.

Or when asking an LLM for a comparison matrix or pros and cons between choices ... beware paid placements or sponsors. Bias could be a result of available training data (forgivable?) or due to paid prioritization (or de-prioritizing of competitors!)

In the GP's analogy, the Bentley can be rented for $3/day, but if you want to purchase it outright, it will cost you $3,000,000.

Despite the high price, the Bentley factory is running 24/7 and still behind schedule due to orders placed by the rental-car company, who has nearly-infinite money.

Exactly, my company started carefully dipping their toes in to org wide AI mid last year (IT has been experimenting earlier than that, but under pretty strict guidelines from infosec). There is so much compliance and data privacy considerations involved.

And for the record I think they are absolutely right to be cautious, a mistake in my industry can be disastrous so a considered approach to integrating this stuff is absolutely warranted. Most established companies outside of tech really can’t have the “move fast break things” mindset.

Yes, many games do that too. Depending on how many shaders the game uses and how fast the user's CPU is an exhaustive pre-compile could take half an hour or more.

But in reality the exhaustive pre-compile will compile way more than will be used by any given game session (on average) and waste lots of time. Also you would have to recompile every time the user upgraded their driver version or changed hardware. And you're likely to churn a lot of customers if you smack them with a 30+ minute loading screen.

Precisely which shaders get used by the game can only be correctly discovered at runtime in many games, it depends on the precise state of the game/renderer and the quality settings and often hardware vendor if there are vendor-specific code paths.

Some games will get QA to play a bunch of the game, or maybe setup automated scripts to fly through all the levels and log which shaders get used. Then that log gets replayed in a startup pre-compile loading screen so you're at least pre-compiling shaders you know will be used.

What most affects discourse isn't someone's name, but certain data one can find out if one knows someone's name.

What kinds of data? Depending on the conversation, it could be: age, nationality, academic credentials, profession, criminal record, etc.

The net could use a standard way to verify details that matter about a user. This would let users keep their real names private, without making it so easy for bot armies, paid agitators, bullshit artists, trolls, and others to poison public discourse.

Hey! I have a similar setup. Mostly done as a thought experiment, luckily I don't have to deal with a war.

Instead of using the Python interface directly, I used MQTT as the gateway.

I disliked all the existing MQTT servers (who writes network-facing software in C++!?!?), so I adapted the Mochi server a bit to add support for automatic Let's Encrypt certs: https://github.com/Cyberax/lenc-mochi

One problem is that LoRa is low-bandwidth, so I had to pick and choose what I transmit. I ended up defining a schema that bit-packs all the important (for me) sensor state in just 32 bytes.

As another thought experiment, I'm going to connect it to a pair of InReach satellite transceivers over Bluetooth :)

Amazon turned me off selling completely. I was subjected to an obvious fraudulent buyer on a high value item ($5k) and they did everything in their power to make it as painful as possible for me to fight:

- An A-Z claim from the buyer was denied by Amazon for fraud (supposed non-delivery of the item), yet their returns department auto-approved a return for the same order just 12 days later.

- The customer returned a completely different item with documented serial number/weight discrepancies and seller-provided video evidence, yet I was left with no recourse.

- The customer then filed a fraudulent credit card chargeback. I won the first round, but Amazon refuses to participate in second-round disputes - so despite overwhelming evidence of five separate fraud attempts, they sent a generic email and docked $5k from my seller account.

- Amazon then refused to answer any further communications, including basic disclosure of which card issuer was involved or what evidence was submitted - making any independent appeal impossible.

- Every dispute stage (A-Z, returns, chargebacks) required rebuilding the fraud case from scratch. Zero continuity, and zero care for an independent seller with a strong track record of sales and feedback.

If you think the world is shifting away from the United States, or that Trump isn’t having his way with virtually every trading partner on the map, then it seems you are falling victim to strong anti-US rhetoric. This rhetoric isn’t based in reality. The US leads the defense strategy of the entirety of Europe, and Europe has no other alternative. There may be some politicians that want to choose the US as “the loser”. But that’s just not really an option given the size of our economy and the size of our military.

> I'm not familiar with the healthcare sector. Is this where the job growth is?

Real world, less so; HN-focused areas, absolutely. Nearly every mediocre, tech-focused healthcare start up is just a money siphon, no matter how many times their founders talk about “disruption”.

In actual healthcare, there are massive nursing shortages, and lots of need for people doing actual, hard, brick-and-mortar work.

LOL, yes.

I just tried to put Monterey on a 2021 MBP and holy hell.

USB installer. "Not supported OS, you can quit, or install in reduced security mode". Reduced security is fine for me.

"Installation of Reduced Security failed." Cool.

"Get the IPSW and do a DFU install". Nah, you can't do that. "Drag the IPSW onto the target Mac where it says DFU in Apple Configurator". Nope. No error, just nope.

Dig dig dig. "You might need to do this from an older computer. Even an Intel MBP running Ventura". Hey look, I have one!

Alright, install Apple Configurator.

"Nope. You need Sequoia to install Configurator."

Jesus wept. This is an OS that is 4 years old, on a 5 year old laptop. Apple, "It just works".

Find an old version of Configurator from some guy on Reddit that zipped one up.

Now we can do an IPSW install.

Good luck, mortals.

> Assume FP64 units are ~2-4x bigger.

I'm not a hardware guy, but an explanation I've seen from someone who is says that it's not much extra hardware to add to a 2×f32 FMA unit the capability to do 1×f64. You already have all of the per-bit logic, you mostly just need to add an extra control line to make a few carries propagate. So the size overhead of adding FP64 to the SIMD units is more like 10-50%, not 100-300%.

Toxic materials can make you real wacky, but that has nothing to do with anything psychopathic.

Unless somebody puts some effort into combining the two, which does happen.

Psychopaths would have done damage whether they were affected by chemicals or not.

Now you do bring up a major conundrum which many people may not want to face at all, and would not know what to think no matter if it was true or false.

You make a legitimate observation whether that is coming from outside the USA or from freedom-loving Americans.

Not everyone is like that. In fact, OpenClaw's true "power" is unlocked when the user gives it full access. That's what the overwhelming majority of hype is coming from. Most people who actually get a lot of value out of it don't run it on e.g. docker containers on VPSs that can only be accessed via Tailscale + SSH.

Quick question but what if I use claude code itself for the purpose?

https://github.com/rivet-dev/sandbox-agent/tree/main/gigacod... [I saw this inShow HN: Gigacode – Use OpenCode's UI with Claude Code/Codex/Amp] (https://news.ycombinator.com/item?id=46912682)

This can make Opencode work with Claude code and the added benefit of this is that Opencode has a Typescript SDK to automate and the back of this is still running claude code so technically should work even with the new TOS?

So in the case of the OP. Maybe Opencode TS SDK <-> claude code (using this tool or any other like this) <-> It uses the oauth sign in option of Claude code users?

Also, zed can use the ACP protocol itself as well to make claude code work iirc. So is using zed with CC still allowed?

> I don't see how they can get more clear about this, considering they have repeatedly answered it the exact same way.

This is confusing quite frankly, there's also the claude agent sdk thing which firloop and others talked about too. Some say its allowed or not. Its all confusing quite frankly.

The team that built Erlang (Joe, Robert, Mike, and Bjorn) didn't know the actor model was actually a thing. They wanted to build reliable distributed systems and came up with the isolated processes model you find in Erlang today. Eventually (probably when Erlang was open sourced?), folks connected the dots that the actor model was the most accurate description of what was going on!

I don't think this is as much of an issue as you are making it out to be. I have my Steam Deck on the main branch release which seems to exclude it from downloading precompiled shaders. When a game updates it has to compile the shaders first, but even on a big game this does not take an unreasonable amount of time. Less time than it takes for game updates to download at least.

Steam could improve the experience here by having the shaders compile overnight in the background so it presents zero delay but the current way doesn't bother me much at all.
