Nobody says it is a secret cabal. It is very frustrating when people misstate other people's beliefs

There are politicians and activists that have been pushing for lower car ownership and they do it openly. Motivations for this vary.

> There is an old and tired cabal of manufacturers wanting to generate a moat and push prices up high.

Two things can be true at once.

Doubt: the APQ-181 radar on the B-2 is a Ku band radar, about 15 GHz. Tamara is about 1 GHz. This is entirely incompatible frequency ranges.

Also, the APQ-181 is a LPI radar, which means it’s specifically designed to avoid correlation of signals such that you can track by the signals emitted. There are presumably some downsides to working in LPI, but the upside is that the signal is designed to be indistinguishable from an increased noise floor.

> Fluoride based toothpaste does not increase dentist margin though right?

I mean, that's under attack now.

"The Department of Health and Human Services is directing the Centers for Disease Control and Prevention to make new recommendations on the addition of fluoride to U.S. water sources. HHS Secretary Robert F. Kennedy Jr. has blamed the fluoridation of water for a number of health problems."

I think the hygiene issue is somewhat exaggerated. Early printing often didn't prioritize properly dried filament so the output often bubbled and had many pockmarks and imperfections where bacteria could grow. If you look at modern prints they are quite smooth and consistent.

Even so, if you want to be perfectly safe then apply a coat of polyurethane varnish and let it fully cure. That will seal any holes or voids where bacteria might grow, insulated from cleaning solutions.

The Toyota hybrid system has basically no wear items. There are no clutches, belts, or delicate hydraulic systems. The whole thing is made with big hardened steel ring gears and two electric motors. There are taxis in Vancouver with over a million KM clocked with nothing other than fluid changes and brakes/suspension.

Nobody was debating whether that was right or wrong simply that any cheap prices are a short term anomaly and not sustainable for those businesses.

The fact still stands, very rarely are Chinese EVs priced like that and it’s really only for the bare bones budget ones that barely meet local safety standards. I think about VF in Vietnam they have a 2 door 4 seater that’s $12k. Only a single airbag and I doubt any real modern crash standards built in. Works great for that market but not for the US.

Only sort of related, but I'm almost completely unable to smoke anymore. I used to smoke heavily in my early 20s (33 now). Now if I take more than one hit of anything, I'm liable to have an anxiety/panic attack. I can hardly move and I get these awful chills. The way it's consumed hardly matters; even with edibles, I can only have 1-2mg. I've ceased entirely and I don't regret it at all.

I'm sure there are at least a couple of other causes (genetics, early life diet), but I think it did worsen some hormonal imbalance issues I've had too.

As Dennis from Monty Python and the Holy Grail would say, "come and see the violence inherent in the system!"

The thinking is rooted in exploring the full breadth of coercions available to the state, with both actual and implied violence.

Of course it's vastly more likely a person who has been fined will pay the fine, or the other entities which he relies on for money (his employer, his bank) will extract it from his assets, or if he has no such assets, the state will start to go after his personally-held assets. As you know, the UK has safeguards, the state can't sieze your residence to make you pay a fine, but they can sieze second homes, or more relevant to this discussion, your car -- if they don't judge it essential for your livelyhood. The UK state isn't looking to reintroduce debtors' prisons, they prefer to keep a wrongdoer economically active, provided they don't think it'll lead to further harms; so in the case of someone fined to buggery, and banned from driving (let's imagine not just parking fines but persistent reckless driving), and could technically walk or get the bus to work, the state may well sieze the car and auction it.

But then if the criminal tries to keep the forfeited car locked up, the state then authorises its burglary, and we can then keep upping the ante between the unstoppable force and immovable object; does the state give up trying to sieze the car (and thus not enact justice; the criminal ultimately did not pay his fine), or does it proceed? And if it proceeds, what can the criminal do to prevent it, that is "non-violent"? If baliffs turn up at his door with a warrant to seize the vehicle, do they just go away, empty-handed, if he politely says no? Or do they smash down the door and ransack the place looking for the keys? Do they wrench open the garage door and lift the car out? If they do that, are they being violent yet? If the man tries to resist the baliffs searching his abode for car keys, is that violent yet? If they then try to stop him resisting (e.g. by having authorised police attempt to restraint him, without using weapons), is that violent yet? If he arms himself in order to resist being restrained to resist having his car siezed, are we now at the point of violence, even if he doesn't need to use the arms? And so we can go on, action and counter-action, there is always a further escalation available, and it will, at some point, reach violence. You can't have a state that insists on a course of action and a citizen who insists on rejecting that course of action. Someone has to prevail. It is almost always the state.

The cases we see where the state doesn't prevail look like Mexico vs drug gangs, or Lebanon vs Hezbollah. Places where armed paramilitary organisations are the de-facto government. That's the sort of place where, say, a Hezbollah fighter could get a parking fine, and the government would ultimately not collect and the criminal can lead a happy life, because he has a whole set of organisations (including employer and bank) who lead an armed resistance against the state, and are more powerful than the state, so they prevail.

Good call out on infrastructure. Infrastructure maintenance isn't cool and there's no ribbon cutting ceremony for fixing existing capital. The new government is finally allocating more resources for DB.

Train frequency is the most important aspect of transportation. It's probably more important than max speed or even ticket price. A train every 15 min means you don't have to make an appointment because one will be coming soon. At half an hour you will need to study the timetable and plan your life around it.

This is an interesting one.

On one hand it’s hard to disagree with the statement “it should be clear what your product does in a single glance”. In fact there’s a whole meta that’s been developed around this, with well established common wisdom on how to structure your landing page to quickly frame value to prospective users, call them to action, etc.

On the other hand it’s kind of fun to stumble upon something and feel like you missed the beginning of the conversation, and to figure things out piece by piece based on context.

I was also confused when loading this website but it led me to trying the app and it was kind of fun.

Sometimes the most optimized, clearest path isn’t necessarily the preferable one.

I'm not sure why anybody other than a social security acturiarian would care about the children per woman rate.

More on point is:

"Some 86% of women ages 40 to 44 are mothers, compared with 80% in 2006, according to a Pew Research Center analysis of U.S. Census Bureau data." That was as of 2018 and the first link that came up.

Clearly men and women are still making babies. This number if accurate is actually surprisingly high.

The oddest tree I know of is poplar, which is incredibly common around here and is basically considered junk wood. Turns out, those individual, fast-growing trees are in fact stems of a large underground root system.

One of these trees has 47,000 stems:

> Most agree [...] that Pando encompasses 42.89 hectares (106 acres), weighs an estimated 6,000 metric tons (6,600 short tons) or 13.2 million pounds, and features an estimated 47,000 stems, which die individually and are replaced by genetically identical stems that are sent up from the tree's vast root system, a process known as "suckering". The root system is estimated to be several thousand years old, with habitat modeling suggesting a maximum age of 14,000 years and 16,000 years by the latest (2024) estimate.[

Everybody uses Microsoft, because they have to. Not because they love it or even like it.

That's the root cause of why the stores failed.

Think about it: how many people openly say that they love to use Apple products vs people who openly say they love Microsoft products?

I have never ever heard anybody say/write about a great Microsoft product.

I write all of this as someone who uses Windows, Teams and other Microsoft crap every day all day.

> People spend a lot of time printing generic bins and baseplates that would be better spent just printing custom bins

3D printing with a modern printer is set and forget. You send the print file to the printer and you go get it a couple hours later.

Still faster than waiting for a package from Amazon and lower resource usage than driving to the store.

The customization comes everywhere from picking the bin you want to selecting the color filament to match your layout. Gridfinity isn’t my thing but people who are into it are usually customizing something, from the color to the baseplate.

I never understood this argument. What does it even mean not having billionaires. These “billionaires” are share holders in their own company. They don’t have liquid cash worth billions.

It’s the value of the shares that make them billionaires.

Is the politician suggesting they should liquidate their shares? Who will own the company then? Will they keep changing ownership and diluting shares if it reaches billion dollars?

This argument doesn’t even make sense.

As far as taxes go, these are unrealised gains. Even for Capital gains to trigger, there has to be some kind of transfer/sale. And transfer/sale has a different meaning in tax and legal language.

He was recommended by my therapist. Essentially runs an all-inclusive, boutique medical service; expensive, but actually turned out to be cheaper than all the services I'd previously had to use, for the best care of my life. That said, he only sees a limited number of patients (actually just closed new memberships from the web, only accepting referrals until he hits his cap) and only in Georgia.

I imagine there are other boutique providers out there, but this has been a first for me and given me hope that healthcare might not be so goddamn awful for everyone eventually.

> There is no intelligence, however defined

Ok, I choose to define intelligence as having the ability to transform vectors of tokens with matrices. There, LLMs are now intelligent and what you just said is incorrect, because this is one possible definition of intelligence.

Seriously, nobody can argue against what you are saying if refuse to elaborate on what exactly you mean. Provide the definition for "intelligence" you are using.

Isnt it possible that people smoking weed were treating conditions like anxiety or depression and are more likely to commit suicide in the first place? Weed has had a real deficit of actual study and although some people can get a dependency on it I have a hard time qualifying those people as addicts when stopping weed is so much less dangerous and difficult than other substances. Its a complicated topic that requires quite a lot of care when you talk about it, because labelling someone as an addict is a tall order and also weed has been a moral panic for so long.

You have confused someone being able to convincingly walk down a certain line of logic for that person actually believing that line of logic. The author states one of many reasons right afterwards why he thinks that is a really bad idea:

>Why, though, shouldn’t we just double-down on orthodox prohibitionist remedies? Because you wind up punishing a vastly larger number of innocent people, that’s why. [...] When you ban intoxicants, you conceivably reduce abuse, but you definitely end up punishing an enormous number of innocent hobbyists - as well as the professionals who supply them.

I linked that page because, when I was an alcoholic, I was also an asshole to the people around me. I mooched off my parents, deeply worried my brothers, and refused to pull my own weight even a little bit in the household economy.

But there are plenty of people who drink alcohol who are not assholes because of it. They should not be thrown under the bus because I personally become an asshole when exposed to the substance.

In my experience the HN crowd is generally interested in cutting edge science that is relevant to pop culture.

Ever since cannabis use has become normalized there has been a vigorous debate about its long term safety and the issue is far from settled. This study is another data point that we as individuals can use to make decisions about cannabis use.

You are right that in practices we can't just look at cannabis use in isolation from the rest of a persons lifestyle. However, science almost never starts with a comprehensive analysis. Instead it starts with smaller targeted studies that are then used to build the comprehensive arguments.

So while yes I it would be more useful know the risk of cannabis use relative to drinking alcohol, consumer sugar, lack of exercise, etc... this data point in an of it self is still useful.

That's how people in the USA typically talk about prices, and it is what all displayed prices in the USA (from food on the menu to car prices) represent. Since the article is talking about US car prices, it's the only relevant thing to compare.

Otherwise, feel free to adjust $10k -> $12.5k or whatever the VAT is in your region.

> The cars I work on are from the early 90s and everything is very simple to understand.

If you were to take an older, simple to understand car, and add all of the modern features through aftermarket addons, you would end up with a car that is no longer simple to understand. They were simple to understand, because the feature set was simple compared to a modern car. (And I miss them dearly - can't wait to retire to find the time to find that love again!)

Or Caltrain. The new electrified Caltrain is a massive improvement: it runs at least every half hour all day, every day. I don’t know whether it was intentional on the part of the agency, but they stumbled upon the obvious phenomenon that many people will not use a transit system that runs too infrequently and that, conversely, if you have infrequent trains with low ridership, your ridership might return if you increase frequency.
by raincole | 2025-06-30 13:36:16+00:00
You're right... with a catch.

What you described doesn't rule out {0,1,2... Q-1,Q,Q+1...}, because you only defined how to yield new natural number, but not exclude things that are not yielded that way from N (the set of all natural numbers).

Now, our intuition is to add this missing part into our axioms, right?

So instead:

> 0 is a natural number, and if n is a natural number then so is S(n)

We say:

> For any X⊆N, if 0 ∈ X, and for every n ∈ X, S(n) ∈ X, then X=N.

This is a perfect valid axiom. And it does rule out the nonstandard shit: for a set N' that looks like {0,1,2... Q-1,Q,Q+1...}, we can get X = {0,1,2...}, which is a subset of N'. According to this axiom, if N'=N then X=N', but it clearly doesn't because Q∈X while ~(Q∈N'). Therefore, N' isn't N.

However, this axiom is not included in the commonly accepted Peano Arithmetic! The reason is that this uses second-order logic, and Peano Arithmetic is a first-order theory.

The above axiom effectively defines a predicate, f(X), which accepts a set as input and returns whether the set is N. This is second-order logic.

Peano Arithmetic, being first-order logic, doesn't have such predicate. This is why we can't rule out these nonstandard {0,1,2... Q-1,Q,Q+1...}.

When it comes to ZFC, it's more complicate as in ZFC, 'natural numbers' are ordinals of sets. But ZFC is written in first-order logic as well, and it's known that an axiomatic system written in first-order logic will have nonstandard models. Even if you can rule out {0,1,2... Q-1,Q,Q+1...} by defining PA in ZFC in some unusual way or adding new axioms to ZFC, as long as it's still a first-order theory, it will have 0 (if inconsistent) or multiple (if consistent) models[0].

I have met many smokers with diseases directly related to the habit of smoking cigarettes. I have never met a cannabis smoker in the same situation or that developed it over time (20 years span).

Obviously, cannabis smokers also die from heart diseases but if smoking cannabis was something that would be related to heart attacks we would know by now, a research would not be needed or it would be quite obvious and accepted.

> If Americans can't get a new car for under $25,000 but Southeast Asia can get them for under $10K, something is wrong.

If they were perfectly interchangeable, sure. But if nothing else, lets look at safety and emissions regulations -- different regulatory regimes will absolutely put different requirements onto the build and components. Not an expert in automotive regulation in SEA vs. US, but I'd buy this argument more if the comparison was between, say, Europe and the US.

There's also likely a bunch of soft cost differences -- dealership dynamics, etc. that add a fair amount to the sticker price, and those probably do have some merit to your case.

People don’t take the withdrawal potential seriously.

I’ve had a complex relationship with cannabis over the years, and one of the things that I didn’t understand before getting stuck in a daily habit of heavy use for a period of time is how hard it can be on your body to just stop.

I had major upset stomach and food aversion for a few weeks to the point that I lost 10 pounds, major sleep issues, a major spike in depressive symptoms (not just baseline depression, because I eventually got back to baseline), etc.

Or better yet, don't let 'social pressure' influence your choice of programming language ;)

If your workplace has a clear rule to not use memory-unsafe languages for production code that's a different matter of course. But nothing can stop you from writing C code as a hobby - C99 and later is a very enjoyable and fun language.

Though NASA is certain that the asteroid poses no risk, at least for this upcoming flyby, it's fun to think about how things would go if it did indeed strike. Apophis is roughly 450 meters across and weighs around 30 million metric tons (though i've seen conflicting numbers on its mass), and is moving at over 30km per second. That's a gargantuan amount of kinetic energy.

If the asteroid were to strike, let's say somewhere on one of the continents, the resulting destruction would be similar to the simultaneous detonation of at least a few thousand nuclear bombs minus the particle radiation..... but with so much more impact energy.

This would generate a near-instant super-heated, molten crater at least 15km across and immediately followed by a hypersonic blast wave that would utterly annihilate everything within a radius of at least a couple hundred kilometers. The even faster-traveling thermal pulse in between those two would flash-fry any flammable thing out to maybe twice the distance of the blast wave, and even at the outer edge of said thermal pulse, this includes causing lethal, almost total third to fourth-degree burns over any living tissue.

It would not be a good day for the people of whatever wider region that surrounds its impact point.

Globally, we'd also see atmospheric effects. They'd be nothing like the ones that struck the dinosaurs down into near total extinction, but they'd be noticeable, and would cause social, economic and environmental havoc. It would maybe be comparable to something like the 1815 Tambora eruption, whose climatic effects basically killed summer for much of the world in that year. Only here it would happen in modern times and from a much scarier type of disaster, hammering delicate modern infrastructure and communications.

If Apophis struck somewhere fairly densely populated, like, say, the Eastern U.S, almost anywhere in Europe or somewhere in central to Eastern China, in just seconds we'd have close to the biggest human death toll from a natural disaster in all our history, and the second-order effects of it would kill millions to tens of millions more. I can only think of the Black Death or maybe the 1918 flu pandemic as candidates for worse, albeit much slower killing.

If Apophis were to hit the ocean, things get a bit harder to estimate and guesstimate.

On the one hand, it's "only" 450 meters across, and much of the ocean is damn deep, enough so as to swallow the asteroid whole and mitigate much of its more fiery atmospheric effects. On the other hand all that kinetic energy still has to go somewhere, and so in this case, perhaps creates a massive ocean-spanning series of tsunamis that hit thousands of kilometers of coastline with waves big enough to drown tens of millions of people.

Then again, maybe the word drown doesn't quite describe it. More accurately these waves would be pulverizing, smashing the victims in their way into surrounding objects with enough force to cause catastrophic tissue and bone trauma. Millions would be smashed to death much much faster than they could drown. In a way, it would be something of a mercy.

Fun stuff.
