It doesn't make financial sense when the tax policy of the US is to tax domestic companies that produce things but not foreign companies that produce things and benefit from selling them in the US market.

We don't need to do research to decide what makes "sense". The market will figure out what makes financial sense themselves. The only thing we need to know is what the tax rate for foreign producers should be so that domestic companies are not the only ones shouldering the federal tax burden.

From the spec:

https://modelcontextprotocol.io/specification/2025-03-26/ser...

“ For trust & safety and security, there SHOULD always be a human in the loop with the ability to deny tool invocations.

Applications SHOULD:

Provide UI that makes clear which tools are being exposed to the AI model Insert clear visual indicators when tools are invoked Present confirmation prompts to the user for operations, to ensure a human is in the loop”
Ask HN: Are the tariffs a retaliation after China ruined AI companies profits?
by prompt_overflow | 2025-04-09 20:01:01+00:00
After years of investment and billions spent, any chance of U.S. companies profiting _wildly _from AI has been destroyed by China's open-source models—especially those like DeepSeek.

I don't mean existing closed models aren't useful anymore, but realistically, 90% (or even more) of what can be accomplished with a proprietary model can now be done with an open-source alternative.

This has clearly devastated profit expectations, and investors—who poured money into speculative AI ventures—should be furious. (Think about all money that has being spent so far and remember about R$500 billion investment announcement by OpenAI, Oracle and Softbank)

Could this have been triggered the retaliation into tariffs from the U.S. against China, after they have been destroyed the most prominent and speculative profit market ever created?

it is already super expensive if you want to get an actual work done using their max model. On a midsize project, it cost ca. €200 for my vibe coding tests to get something reasonable done (each call, each tool costs 0.05c). Their normal claude window is super short, and almost unusable for serious work. Stack was python and Nuxt.

Margin as a % is a key metric, more so than margin as a $. It's not always sensical but it's dominant in the business/investment community.

For example, you may announce to public markets that your profit has increased $10M despite margins eroding from 50% to 30%. You will likely be punished in terms of stock price. This is because you sold a lot more or trimmed some expenses (which is short-term good) but you are also now more risky because if sales decrease you will more easily run into trouble breaking even/covering operating costs (which is long-term bad).

Interesting, I thought it might be something like that.

Yea, 'canonicalizing' is really tough (although I don't know if you really need to get it *perfect*) because what is correct is different in different contexts.

Accounting Software as an example again, for the category overall canonicalizing any reference to Quickbooks to the same company makes sense. If you're asking about more specific recommendations though 'Accounting software for sole traders', you might have both Quickbooks Online and Quickbooks EasyStart mentioned, and they are actually slightly different products. Or Netsuite is actually a suite of products that might all make sense in slightly different contexts.

> Worst case, writing a shim for an exact MCP capable server is a) probably not a big deal, and b) will probably be on GitHub this week or so.

That sounds exactly like the kind of thing I would outsource to an LLM. I think people over think the need for protocols here. Most AIs are already pretty good at figuring out how to plumb relatively simple things together if they have some sort of documented interface. What the interface is doesn't really matter that much. I've had good results just letting it work off openapi descriptions. Or generating those from server source code. It's not that hard.

In any case, MCP is basically glorified remote procedure calls for LLMs. And then Google adds a bit of probably necessary complexity on top of that (auth sounds important if we're connecting with third party systems). Long lived tasks and out of band data exchange sounds like it could be useful.

For me the big picture and takeaway is that a future of AIs using tools, some of which may be other AIs using tools communicating with each other asynchronously is going to be a thing. Probably rather soon. Like this year.

That puts pressure on people to expose capabilities of their SAAS services in an easily digestible form to external agents. That's going to generate a lot of short term demand from various companies. Most of whom are not really up to speed with any of this. Great times to be a consultant but beware the complexity that design by committee generates.

I've always had the impression that Ukraine's tech sector is primarily focused on outsourcing or outstaffing for Western companies, so they typically don't own what they build (and it's very custom, boring enterprise stuff anyway).

Russia, on the other hand, has traditionally focused more on building its own products and brands, both for its domestic market (Yandex, VK) and the global market (Karsperky, ABBYY, JetBrains). When a technology they create for themselves turns out to be pretty good, it often spills over to the West and gains global popularity - examples being ClickHouse (originally to support metrics collection at Yandex), nginx (originally a reverse proxy at Rambler), etc. I have a hard time remembering something similar coming out of Ukraine?..

I may be wrong, it's just my impression of it (reading Ukrainian/Russian job postings etc.)

It's funny, people like you will say a study is too small and focused to be worthwhile.

But then we have the case of Alaska, an entire state receiving a yearly stipend(basic income). And the same type of people will say well it's too broad you can't possibly pinpoint any direct effects. https://www.ktoo.org/2015/02/20/alaska-tops-gallups-index-we...

Science is not made for perfection and many studies are _not possible_ it doesn't mean there's nothing useful to gain from it for policy makers. It's also simpler to study smaller groups than effects on entire countries.

I'm actually appreciating this discourse, thank you.

For what it's worth, being an immigrant to the UK, I've watched kind of from the sidelines as similar events unfolded here around brexit. I tried very hard to have sympathy for the views of brexit voters. The problem I have, and I have the same problem with MAGA, is despite having real grievances, is the overall narrative is just lie after lie. The MAGA administration lied to the whole world about "trade deficits", completely ignoring services. Maybe the story rings true for a particular voter, but it is a misrepresentation of the whole truth, or more bluntly, is a lie.

I understand very well that certain people have not felt the benefit of deindustrialisation. I do get it.

You say this:

> The original person I was responding to was asking why this happened (presumably because it seemed irrationally stupid, as I think it does to most people here), and what I'm pushing for is an understanding of the point of view which explains it. If you understand the concerns of MAGA and the strategic concerns of the US Military the tariffs make sense.

No. I just don't agree. They make sense if Europe wasn't consuming billions of USD a year of US services, and the US wasn't growing increasingly wealthier than Europe each year.

Trump is pandering to his base. That makes sense. But the tariffs are just a means to that end, and trying to ratonalise the tariffs in other terms, I just don't agree with.

In any case, I have learned stuff from this conversation. I'm not even saying I am definitely correct, there is a chance I'm wrong and you're correct, and I will keep an open mind about that. Thank you.

I've seen relatively little discussion about these lawsuits, but I do think there is a pretty good chance that SCOTUS will rule these tariffs unconstitutional. (It's certainly more likely than Congress rescinding the powers they've ceded to the presidency.)

Constitutionally, the power to set tariffs resides with the Legislative branch, not the Executive branch. Congress has delegated some authority to set tariffs under certain conditions (namely, emergencies and matters related to national security). But the Court is clear that one branch cannot delegate all of its powers to another. The Court is pretty deferential to the Executive branch, especially in matters of national security. But no matter how much you squint, it's hard to see how setting broad based tariffs on all goods from every foreign countries qualifies under the Emergency Economic Powers Act.

I'm personally most worried about increases in general income levels being soaked up by real estate holders. It's what we've seen happen in the SF bay area rents in response to tech fortunes. I don't see UBI actually increasing welfare much without a tax on land value to make landholding less profitable and redirecting the value of land into the UBI fund.

I've built a large professional network, but I don't have a good way to manage my network or search across my network for finding the right person for the right question or opportunity. I only think of the top 5% I regularly talk to anyways. My ideal tool would be chatGPT for my network, but I haven't seen a good version of that.

lol the state(aka society's strong arm) will always have an immense say in your life even if you are so oblivious to it. Government exists to redistribute money, might as well distribute it to the poor and do it universally.

This study didn't say, we gave 1200 to people and then dictated their lives like a dictator.

Nice, that's very interesting and a commendable achievement!

If that is the case I would really like to see some internals of how the physics engine has been implemented in their pattern. I'm not asking for the rapier port source code, but it is hard to think in terms of a new advertised programming paradgim when there's no working examples.

For example I am very curious to see how a constraint solve is implemented in a SQL-like fashion. You would need various math operations and an efficient matrix representation off the top of my head, and I can't think of how that maps to a SQL-like interface.

Thank you for doing the math - we're only talking about 23 of them? it's entirely possible to capitalize on 23 minutes, but seriously, 23 minutes?

Governments all over the world generally want more surveillance, not less. Brazil in particular will never use it: anonymity is literally unconstitutional in Brazil.

There was a fun period where the brazilian government mandated the use of free and open source software in its computers. I remember lots of people who complained about the quality of OpenOffice. Microsoft managed to put an end to that at some point. After former president Dilma's impeachment, I think.

Author here. That's the answer.

Or at least it used to be the answer when I still cared about analytics. Nowadays, friends send me a message when they find my stuff on social media, but I long stopped caring about karma points. This isn't me humblebragging, but just getting older.

The longer answer is that I got curious about Cloudflare workers when they got announced. I wanted to run some Rust on the edge! Turns out I never got around to doing anything useful with it and later was too busy to move the site back to GH pages. Also, Cloudflare workers is free for 100k requests, which gave me some headroom. (Although I lately get closer to that ceiling during good, "non-frontpage" days, because of all the extra bot traffic and my RSS feed...)

But of course, the HN crowd just saw that the site was down and assumed incompetence. ;) I bury this comment here in the hope that only the people who care to hear the real story will find it. You're one of them because you did your own research. This already sets you apart from the rest.

SAT is NP-complete and planning is PSPACE-complete so it really doesn't matter how much you "scale" your hardware, those are not problems you can solve by scaling, ever.

It seems like you are not framing NP-completeness properly. An NP complete problem is simply worst case hard. Such a problem can have many solvable instances. With some distributions of randomly selected SAT problem, most instances can be quickly solvable. SAT solving contests often involve hand-constructed SATs translated from other domains and the entrants similarly add methods for these "special cases". So NP-completeness isn't a barrier to SAT-solvers scaling by itself.

You were the beneficiary of a bullshit short term policy that has wrecked the global and national economies and think that means it was a good thing to replicate?

Your fun time was extremely damaging to people everywhere but of course, we can pretend "it was necessary because COVID" which we then knew and now it's undeniable, was an absolute farce of hygiene theater.

The people who worked paid for you to do nothing at your parents home. That's all there is. Meanwhile, there also were massive transfers of wealth with the same excuse, from tax payers to the wealthies company owners.

I feel as though this study is only addressing the bottom percentile of questions about UBI, the kind of complaints from people who think "those lazy poors shouldn't be given money". I think most people are able to understand that, yes, people's lives improve when you give them more money. My real questions are macroeconomic. Does UBI create a Keynesian stimulus effect on the economy, or is it primarily inflationary? What is the saving on means testing benefits? How does tax law need to be adjusted to ensure proper dispersal of funds?

Edit: I should emphasis that these questions come from a place of genuine curiosity, rather than simply throwing things up to get in the way of a policy being implemented. I believe larger trials are required to gather better data, with a view towards expanding the pool of recipients.

> Or arts funding in the USSR and other soviet bloc countries.

This is pretty good example why UBI is dangerous. Those funded artists were very happy to suck it up and go along with the regime. The censorship was in place, but self-censorship was even stronger.

Meanwhile a lot of art existed outside of the system with people working some shitty jobs and doing arts in free time.

Exactly. If I plan to visit a country where green shirts are illegal, I'm not going to pack my green shirts into a secret hidden luggage compartment, smug in the knowledge that I'm so clever. I'm going to either not visit or not bring my green shirts.

Same for this. Whether we like it or not, some stuff on your phone are now considered contraband at the US border. Either don't bring them or don't visit.

This is only half correct.

It is true that some/many Rolex AD’s will allocate the most desirable watches to customers with an existing purchase history, and that some customers therefore buy less desirable models in order to earn goodwill with the AD.

However, it is not the case that the most desirable watches are necessarily (or even on average) the most expensive models. For instance, it is generally the steel models that are the most desirable and command the highest markup from MSRP on the secondary market. The Submariner, the Daytona, the GMT-Master II: almost all of Rolex’s most iconic, most in-demand, most "flippable" watches are the full steel versions, which are the cheapest versions of those model families.

To give a concrete example, it is generally considered easier to get a full-gold GMT (~$43k) or a two-tone (half steel, half gold) GMT (~$18k) at an Authorized Dealer than it is to get the full steel version ($11k).

I like the concept.

However the UI is a little confusing (on mobile anyway).

I might suggest you don't present the pre-set range values, as it makes it a lot easier.

Have you considered - perhaps in a way to gamify it a bit more - giving a first hint, and hiding the next 3 unless the player asks for them? It would add an element of 'getting it in 1 go' etc. I'd imagine one or two-shot winners are also more likely to share their results. More potential for your app to go viral.

US wont end up in the situation that UK finds itself in because the land it occupies is some of the most productive land on earth and at a similar scale as china. The incredible wealth of america, is that its a land mass that in the old world would be supporting 500m-1.5b people, but is divided only amount 350m.

The city at the center of the Missouri and Mississippi if it were in europe would be a major civilization. In the US its saint louis. The US, CA, and AU have an option few countries do -- at any point they want nominal gdp growth all they have to do is open the door.

I agree with you though that china's incredibly impressive.

I wish Android had a better backup story. If you're using iOS, it's as simple as the article describes. If you use even modern Android on modern Pixel, backup only includes a fraction of what you need to recover. Things like Signal keys, 2FA tokens, and more were not included in my last backup.

GrapheneOS had an opportunity to do this 1000% better... and they instead ship a kinda broken fork of SeedVault, which they have been intending to replace for a long time now.

Several incorrect assumptions in this take. For one thing, 16 bit is not necessary. For another 140GB/token holds only if your batch size is 1 and your sequence length is 1 (no speculative decoding). Nobody runs LLMs like that on those GPUs - if you do it like that, compute utilization becomes ridiculously low. With batch of greater than 1 and speculative decoding arithmetic intensity of the kernels is much higher, and having weights "off chip" is not that much of a concern.

It is sad that opposition is not being acknowledged. There was a determined effort to restore Canada's tariffs to what they were that passed the Senate and was then blocked by an unusual maneuver from the speaker of the house which in turn got him excoriated by some Republicans in congress. Some of the biggest conservative power players and possibly the most famous and successful conservative lawyers are teaming up to challenge emergency executive tariff powers in court. Meanwhile US citizens retain high confidence in elections and Republicans nationwide are complaining in a panic that these moves will turn their precincts Democratic for decades.

But of course you are totally right. No adults anywhere. Keep thinking that Europe can count on others to pay for its defense while buying all the energy they need from Moscow. At least you have adults in the room, right?

What really stood out to me is that they say the factories will produce their own power on-site, with approvals for power plants happening "faster than we've ever had before", because the grid is "at risk of bombings". Which suggests to me that it not just about having manufacturing local for the sake of it being local or to stop money going offshore, but because it is preparing for war.

> The idea would be that different parts of the supply chain would build factories in the US to avoid tariffs.

Building a factory is a 3-5 year task, with a decade-long payback time. And at any point, tariffs can be removed, making all that investment futile.

And even then, there's no guarantee that the factory is going to help people. If it's a lights-out facility staffed with robots, then it'll just be producing more expensive goods, with all the profits staying in its owners' pockets.

"more" usage likely means that they have a limited number of GPUs, and what models you get access to depends on how much you've used them recently, but also on how busy the GPUs are at this moment.

This is also how batching works for API users. If you don't need the results immediately, you can give them a batch with an attached 24-hour deadline, and they'll slot you in whenever they expect low usage, in exchange for better prices.

It really depends on what your filter bank looks like. If it's a 4-band parametric EQ, then sure, you can have four biquad IIR filters and that's it. But if you've measured an impulse response and want its inverse (e.g. through a Wiener filter), that's not what you have; you simply have another impulse response (effectively closer to a N-band graphical EQ where N >= 100), not a parametric EQ.

As a nitpick: You always know the filter transfer function, it's the DFT of the impulse response (and without the impulse response, you obviously cannot convolve).

My Lenovo from last year still has non-soldered NVMe drives. I would probably just install Windows on a separate partition and set it to boot to that, then install a few games and set my Chrome homepage. I bet CBP won't be mucking around with bootloader settings looking for Linux, and even so it would be pretty trivial to just remove GRUB from the EFI partition for the travel days.
