IMO for the Garmin vs alarm clock example, it's less about costs and more about power & branding.

The retailer & the wholesalers involved all have a reasonable idea about what people will pay for the products in question. The portion of that final consumer price that stays with the retailer is just the result of negotiation.

The retailer can likely buy decent alarm clocks from anyone, so alarm clock makers & wholesalers have no pricing power and the retailer can demand high margins.

But the retailer can only get Garmin from Garmin. If Garmin has done a good job promoting the brand, such that the retailer feels they have no choice but to stock it, they will have to suck it up and accept low margins.

and trying with cd quality audio? from my recollection (using a bose qc 25 in passive mode) from my first setup it changed it a little but i cannot describe it nowadays, i concluded the difference was "better" and kept it for (too?) many years now. funny thing i do remember was adding AutoEQ in twice - once through APO and once through Peace. but i notice it now more when im not listening via my headset, its subtle.

sounds like a win though on the Koss KSC75 regardless though, just makes em more portable to other devices for you

> focus on [...] the few points that brainpower is really needed

The person you're responding to is talking about it from an educational perspective though. If your fundamentals aren't solid, you won't know that exponentially smoothed reservoir sampling backed by a splay tree is optimal for your problem, and ChatGPT has no clue either. Trying things, struggling, and failing is crucial to efficient learning.

Not to mention, you need enough brain power or expertise to know when it's bullshitting you. Just today it was telling me that a packed array was better than my proposed solution, confidently explaining why, and not once saying anything correct. No prompt changes could fix it (whether restarting or replying), and anyone who tried to use less brainpower there would be up a creek when their solution sucked.

Mind you, I use LLMs a lot, including for code-adjacent tasks and occasionally for code itself. It's a neat tool. It has its place though, and it must be used correctly.

> I would dismiss this article as pure fantasy.

Why? The article starts from the point where Nike pays $25 per shoe boarded into a container on a boat, where that number covers all expenses until that point. Yes, this includes the shoe workers' wages, but it also has the factory construction and maintenance, manufacturing equipment, the inputs that go into the shoe, transport to get the shoes packed into a container and to the port, etc etc.

Interesting. How will (physically) AI install a new HVAC system? There must be some form of physical presence to get the job done. And, the current set of installers have a difficult time as it is (running duct work, low/high PSI lines, etc).

Again, how will (physically) AI take over lawn maintenance? Do you expect a fleet of self-driving lawn-mowers to take to the streets? How will they get to your place? Who will be managing them? So many questions.

Personally, I think the AI hype is way overblown. Sure, AI can help give better data for these areas, but I highly doubt AI will take over. I think AI can help smart people get even smarter (better ways to mow, more efficient ways to run HVAC lines, etc), but at the end of the day, you still need physical presence for many/most jobs.

I think the common consensus is that the primary benefit of fluoride is topical, not systemic:

* Initially, fluoride was considered beneficial when given systemically during tooth development, but later research has shown the importance and the advantages of its topical effects in the prevention or treatment of dental caries and tooth decay. [The Fluoride Debate: The Pros and Cons of Fluoridation; Prev Nutr Food Sci, 2018; https://pmc.ncbi.nlm.nih.gov/articles/PMC6195894].

* The actual mechanism of fluoride action is still a subject of debate. A dogma has existed for many decades, that fluoride has to be ingested and acts mainly pre-eruptively. However, recent studies concerning the systemic effect of fluoride supplementation concluded that the caries-preventive effect of fluoride is almost exclusively posteruptive. [Systemic versus topical fluoride; Carries Res, 2004; https://pubmed.ncbi.nlm.nih.gov/15153698/]

* As noted by Thorrez, your link does not mention topical application vs systemic ingestion. There is a publication from the CDC however stating that the benefit of fluoride is mainly topical:

> Fluoride's caries-preventive properties initially were attributed to changes in enamel during tooth development because of the association between fluoride and cosmetic changes in enamel and a belief that fluoride incorporated into enamel during tooth development would result in a more acid-resistant mineral. However, laboratory and epidemiologic research suggests that fluoride prevents dental caries predominately after eruption of the tooth into the mouth, and its actions primarily are topical for both adults and children (1). [https://www.cdc.gov/mmwr/preview/mmwrhtml/mm4841a1.htm ; 1999].

This material was covered in depositions for TSCA Fluoride trial in 2018, where Casey Hannan (director of the division of oral health at the CDC) was the examinee for the deposition. A temporary upload of a clip from this deposition may be found at https://0x0.st/8Lom.mp4.

I wrote my Senator, Dick Durbin, prior to the November 2024 election, begging him to do something to shore up the legislature, prior to Trump's possible return to office.

He responded that he's not allowed to discuss campaigning and that I can instead donate to his 'friends' network (PAC?)

I don't think the Dem establishment really opposes Trump at all...

> is it a matter of absolute capacity still being insufficient for current model sizes

This. Additionally, models aren't getting smaller, they are getting bigger and to be useful to a wider range of users, they also need more context to go off of, which is even more memory.

Previously: https://news.ycombinator.com/item?id=42003823

It could be partially the DC, but look at the rack density... to get to an equal amount of GPU compute and memory, you need 10x the rack space...

Now compare that to an NV72 and the direction Dell/CoreWeave/Switch are going in with the EVO containment... far better. One can imagine that AMD might do something similar.

Anecdotal but I haven't seen a 2nd-hand bookshop in years however those little "tiny libraries" where people just donate their books are in abundance. What I've seen other used-item shops are doing these days is checking online what things are worth and selling them for very slightly less and it seems like this has to be a death-knell for secondhand stores in general.

And I know they have to do this, everything donated has to be checked to ensure safety and cleanliness, it costs them money to keep the shop open and staffed. But if you can't actually save money by buying secondhand goods there then why would anyone shop there?! It's a 10 - 20 percent discount on goods that may be years old when Amazon rotates these discounts through new goods 24/7.

Yeah Nix seems like an insanely useful concept (declarative, reproducable, diffable, source controllable definitions of linux environments). But actually using it is a nightmare.

I think there's some point on the spectrum between "commit your dotfiles to git" and Nix that would be useful, I don't know what it is though. Containerization is kinda like this, but they're entirely imperatively defined rather than declarative and I wouldn't really want to use a docker container as my main system environment.

It can be more sinister.

If judiciary blocks X, then trump will say "these are the real bad guys, they are as worse as the dems, lets remove them". And BAM ! You have a dictator.

The sad part is that one of the most powerful nation in the world is filled with idiots who will lap up the above argument.

I would say that all this current situation is because of corporate greed, leading to a skewed distribution of wealth, leading to the evolution of a class of voters who are desperate, gullible and mis-informed.

For context, this particular article is a cool deep dive into how Nix works, but it doesn't represent what using Nix + Nixpkgs is like in practice. I've been using Nix personally and professionally for almost 10 years now (yikes has time passed quickly!) and I have never needed to operate at the level of derivations like this.

Sure, my post was not expansive enough to account for criminals and the mentally ill. The bottom I referred to is for people without means, but with capacity to care for themselves.

The hard part of that conversation is that we consider criminal offenses as the only grounds for forcibly incarcerating a person. Mentally ill people need policies that will better protect them fron themselves and their neighbors BEFORE they commit crimes and end up in prison. We likely need new models of mental institutions and new laws which allow people to be committed when it is in everyone’s best interest… yet somehow avoid the abuses and horrors of the past. A very hard problem indeed.

Literally the exact opposite. Government cheese was created because due to subsidies, there was way too much milk that was going to be dumped into the nearest river until the Govt paid the farmers to convert it all to cheese and bought it and shoved it into storage to prop up cheese prices.

It is the definition of over-abundance, since all the farmers were going to have to shoot their dairy cows to actually afford to keep some around and continue producing milk

I was very hopeful for the UK when the Bexited because the EU political machine has become as what I perceive as independent of the people's will but it seems it rather went down from there. People being tried for "silent prayers," arrested for protesting violence .. "Online safety" just seems like an excuse rather than actually making things better. Gab.com also recently posted intimidation attempts at censorship well outside of the UK's authority. I disagree with much of their content but I'm so very thankful for the 1st amendment! I totally understand bitchute's position. The UK market is likely not worth the hassle but I'm sad that geopolitics have more and more effects on the once free internet.

No matter where you stand, I'd be happy to hear some Brits' opinions on that OSA!

Whether or not many people have estimated the odds is not what defines what a bet is, it's just something that people placing a bet are going to look at.

Derivatives exchanges are handled separately from betting because they have other tangible benefits the to financial marketplace. I'm not sure I buy the pitch that prediction markets should fall into the same carveout at face value, but why has nothing to do with how many stats are run.

> Remember that China promised trump in term 1 to massively import US goods and reduce fentanyl

China stopped selling unlicensed fentanyl to the USofA, it later stopped supplying fentanyl to both Mexico and Canada.

The problem was that criminals in the USofA and Mexico purchased precursor chemicals in bulk and made their own fentanyl. Restricting precursors led to pre-precursors being purchased in bulk for drug labs to make their own precursors in order to make fentanyl.

The fentanyl problem continued under Trump and rapidly grew in size during his first term.

In 2021, Mr. Biden issued an executive order imposing sanctions on individuals and companies engaged in the illicit opioid trade. His Treasury Department put sanctions on more than 300 individuals and entities, freezing entire networks of fentanyl suppliers and traffickers out of the international financial system. In 2023 and 2024 he identified China as a major illicit drug-producing country for its role in the synthetic opioid trade — a blow to the reputation of China’s chemical industry. Simultaneously, the Biden administration pushed U.S. law enforcement agencies to conduct aggressive investigations and build indictments against dozens of Chinese citizens and companies that were trafficking fentanyl precursor chemicals into the United States. [..] Biden secured a personal commitment from President Xi Jinping to restart counternarcotics cooperation in November 2023 [..] And we made progress. International fentanyl supply chains showed signs of disruption, forcing traffickers to change sources and tactics. Together with other diplomatic initiatives and an expansive public health campaign, the number of lethal fentanyl overdoses in the United States has dropped. In the 12 months ending September 2024, overdose deaths were down an estimated 24 percent from the year prior.

~ https://www.nytimes.com/2025/03/18/opinion/trump-china-trade...

What has Trump done now he's back in office? Destroyed any cooperation with China on counternarcotics cooperation.

Tariffs alone will not push China’s government to help reduce drug overdose deaths in the United States. In fact, with Beijing already imposing retaliatory tariffs and proclaiming that it’s “ready to fight till the end,” Mr. Trump’s blunt-force tactics might drive China to cooperate less on fentanyl, not more. With the stakes as high as they are, American communities cannot afford a miscalculation.

I honestly wonder why there are such divergent opinions between say git and Nix? (I've never used Nix, but I use git all the time) Is Nix so much harder to use than git?

git also has a clear model (the Merkle tree of file and directory nodes) but a famously unfriendly UI (git checkout does 5 or more unrelated things)

Some people do not like git, but I get the feeling that most people just use it, and get on with their day.

Why the difference with Nix? Maybe because building packages is inherently slower. Whereas you can quickly get yourself intro trouble with git, but you can also quickly get out of trouble (rm -rf, git clone)

Maybe Nix is more stateful? Although the git index/staging area I find to be a fabulously odd piece of state, and honestly breaks all the rules when I think about CLIs

Also Nix does rely on a very big global repo, whereas git doesn't

It also seems that Nix's model is less clean, and perhaps doesn't match the problem domain as well ... there are disagreements on whether it is "reproducible", etc.

Or maybe it's just a harder problem

It looks like the administration is filled with people more interested in making a buck for themselves, rather than do what is best for the country.

I dunno. Somebody literally wrote a guidebook for him to follow, but I haven't even glanced over it.

The stuff I've seen people quote from the book have all been stupid, but the kind of stupidity seems to be a "do X, so you'll get Y" where "Y" is really bad and the author thinks it's good. So I guess I do expect some kind of coherence from him.

That said, I don't remember anybody claiming Project 25 talks about tariffs.

Saying that we are all used to consuming content in a web browser is hardly a controversial comment, especially when posting on HN which is accessed using a web browser. You most likely read my comment on a web browser and wrote it on a web browser.

Additionally, you said yourself the sentence before the one I quoted that you are used to reading documents on the web, so it seems like this "we" also applies to you. So I'm just baffled by both this and the sibling comment.

"We need to anticipate a future where China is equal to America on a per capita basis, but four times bigger"

Four times bigger absolutely will not happen; China's demographic disaster is already baked into the cake. Forecasts suggest China's total population will be around 1.5x the USA by 2100, but the average age / working age population will be in the USA's favour.

> I agree with that critique, though it may be a problem with this specific version of Globalism, not globalism itself.

Well, there's nothing about Globalism that enforces this so it's really a complaint about most if-not all Globalism.

> With only 5% of the population the US would not have nearly enough manufacturing capacity to meet modern needs.

Expand your borders to include say Canada or all of South America. The UK moved up the value chain into industrial jobs while delegating out the cotton farming to their North American _Colony_ (as well as their South East Asian colony).

> If it was handing away money, then why would someone invest in it? They invest because the investment generates returns, in this case massive returns that changed hundreds of millions of lives and provided wealth that was used to buy and invest in yet more things.

Sending over capital goods in exchange for future considerations is not a Mercantilism argument. The reason why somebody would invest in it is because they're a Globalist.

The reason why "we" switched from Mercantilism to Globalism is because it generates more growth but you can't use Globalism arguments in a Mercantilism framework unless you're making the argument to switch frameworks.

(Also Mercantilism is also causing income equality by having an underclass in your colonies to support a wealthier main land; but the mainland isn't going to be complaining about being poor).

That's a terrible example for "parser combinators beat regexes"; those are the three regular operations. (Except that you use zero_or_many in preference to one_or_many.)

That’s the biggest thing I took away from the whole Boeing corporate disaster

You need to maintain at least a minimum amount of internal competency in almost all areas

If you completely give away a capability to other countries (in this case, fishing knowledge and labour) it is much harder to bring back than just coughing up the money

Those sectors you let die might not matter right now, but they might matter later. And you might have to scale up fast.

At no point was Hillary Clinton 100% guaranteed to win the election. 538's final call right before the election was 65% Clinton, 35% Trump; or in other words, under Nate Silver's model, Trump had a 35% chance of winning. And he did win, and just barely at that.

The obeying in advance and reflexive glazing is scary in a Twilight Zone or slow-start-of-a-zombie-movie sort of way, but the fact that Trump is playing very fast and loose with due process, talking seriously about "deporting" American citizens and is actively applying economic death penalties to people on his bad side (like the EO stripping security clearance not only from Chris Krebs, but everyone who happens to work at his current employer) is scary in a "is the US as we know it actually going to survive this?" kind of way.

If not, and no one else is, then there's a chance that someone like Trump might try to do something like that himself. That's what he does. He sees someone else getting away with something bad, tries to do it because he thinks he'll get an advantage, gets caught, and complains about how unfair it is that he got caught.

Just the other day, I got a pair of shoes at Walmart for TREE FITTY.

The most comfortable pair of shoes I own are also from Walmart and they cost less than twenty bucks.

How do my $3.50 shoes from Walmart fit into this picture that justifies why Nikes are $100?

This article fails the smell test. Or maybe it’s Nike’s business model that is failing the smell test, I’m unsure.

Also, anybody commenting who claims they “need” a pair of Nikes for their special feet should try being desperately unemployed and borderline homeless for a while.

You don’t “need” anything.
