> Which means 40% more road maintenance.

Nope. You've overlooked two things, one possibly minor and one major.

The minor one is that road maintenance is not just due to the need to repair damage caused by vehicles. Roads are also damaged by things as daily and seasonal temperature variation, UV from sunlight, oxygen, erosion and soil instability, and others.

An increase in damage from vehicles would might shorten the intervals between needed maintenance, but would not be a simple X% more vehicle damage means X% more maintenance.

The major one is that ICE cars need gas. Let's imagine a city where everyone drives an ICE and then switches to an EV and math this. To make things as comparable as possible let's say all the ICE cars were Hyundai Kona SELs, and they all switch to the Hyundai Kona Electric SEL.

The ICE Kona SEL weighs 3240 pounds and gets 28 mpg. The Kona Electric SEL is 3759 pounds, which is 16% more, so would be 80% more damage. Let's use the amount of damage caused by the ICE driving 1 mile as our unit of damage, so the EV causes 1.8 damage per mile.

Let's say that gas is delivered to the city's gas stations by a 5000 gallon tanker truck. The gas is loaded onto the tankers at a distribution center that is 5 miles from the city. It arrives at the distribution center by rail.

A 5000 gallon tanker will weigh somewhere in the 10000-15000 pound range when empty. 5000 gallons of gas is about 30000 pounds, so when the tanker leaves the distribution center it will weigh 40000-45000 points. Let's go with the low number. That's 12.346 as much as an ICE Kona SEL weighs, so that tanker will do 23000 units of road damager per mile. That's ~116000 units of road damage on the 5 mile trip to the city. As it goes around unloading the damage per mile goes down to 90 units per mile when the tanker is empty.

When that 5000 gallons of gas is later sold to the ICE Kona SEL drivers that will result in 140000 miles of driving and so 140000 units of damage.

If everyone switched to Kona Electric SEL that same 140000 miles would result in 252000 units of road damage, which is 112000 units more but it would also eliminate the need for 5000 gallons of gasoline delivery, saving 116000 units of road damage from the tanker. (Actually more because I'm ignoring the tanker damage once it gets to the first gas station and starts deliveries).

These numbers are going to depend a lot on what ICE and EV you compare, and how far the gas travels by tanker, but the above numbers illustrate that you definitely need to take into account the reduced need for gas delivery when estimating what a switch to EVs will do to the roads.

It's a visceral thought experiment, intended to instill a sense of bewilderment at what being falsely accused actually feels like to someone who seems to offer a normative assertion that privileges bad-faith accusers, without actually causing any of the harm of a real false accusation. That is topically relevant and experientially informative while being restrained enough to not be actually harmful.

"radical hatred of content creators" is a very harsh and specific allegation. I wasn't aware that Kahle was considered such a bad actor. I did some googling and wikipedia-ing and can't see much that supports that claim. I am very open minded to the nuances of IP rights vs information-wants-to-be-free so I'd love to hear more details about your position particularly as it relates to the federal depository designation.

>FWIW our CS program mandated a programming languages class and the first third of the class was taught in Scheme.

This is important but doesn't replace having a dual-track intro sequence. The reason one has "physics for physics majors" isn't because physics majors need to learn some of this complicated stuff ASAP. They definitely don't, and I don't doubt students in the program will eventually get a well-rounded education. But it's a good idea to give incoming students a taste of what the field is like as soon as possible, so they can see if they like it or not. (Essentially it's a "weeder", but for the students' sake so they can self-select on interest and not just instructional staff's sake of being elitist.) Probably some (but not all) professors/postdocs/grad students would scramble to teach the more advanced sequence as it is likely more engaging for them than the current intro curriculum.

To be clear I don't think an advanced intro CS can't be in Python on principle, but such a class probably introduces multiple languages to some degree: they could be toy assembly languages or real ones in addition to the majority of the course content in Python.

In real projects I typically group the classes in a way that makes it easier to read, something like this:

<div class={tw( "block", "transform transition-all", "bg-white ring-1 ring-black/5 rounded-xl shadow-2xl", "max-w-3xl mx-auto overflow-hidden", "group-data-closed/dialog:opacity-0", "group-data-closed/dialog:scale-95", "group-data-enter/dialog:duration-300", "group-data-enter/dialog:ease-out", "group-data-leave/dialog:duration-200", "group-data-leave/dialog:ease-in" )}> ... </div>

I currently do this manually but it would be nice to have some tooling to automate that kind of format.

Everyone is completely missing the point of this article, which I find amusing and terrifying in equal measure.

He is _not_ talking about a SaaS dashboard SPA. He's talking about marketing sites and other content heavy stuff like blogs, landing pages, etc. It mentions this in many places if you go past the headline.

He is completely correct. SPAs should not be used for marketing sites full stop. Perhaps there are some edge cases where it may make sense (though I cannot think of any) but in general, if you are building anything that resembles a blog or landing page with nextjs et al you have done it wrong, close the code editor and start again. I'll give you a pass if you are developing an MVP of something and you need something up very quickly, but if you have any commercial traffic you will thank my later.

I have done a lot of audit work for this kind of stuff. Things I've seen:

10MB+ of React/JS libs to load a simple blog page

Putting images in the bundle, base64d. So badly that the page crashes OOM on many devices.

And my favourite of all time - shipping 120MB (!) of JSON down for a catalog. It literally loaded _the entire database_ to the front end to show _one_ product. It wasn't even an ecommerce site; it was literally a brochure of products you could browse for.

The issues you are talking about are not "society-wide" issues requiring compliance of others.

A better example would be to consider that pre-op transgender people, namely MtF, can share the same spaces that were reserved to biological women. For instance in sport. If I'm a woman and now I have to compete with a biological man in MMA because society chose that it's the new normal, yes, I'm going to suffer from it.

If society decides that it's fair to feed Tiktok to toddlers who end up having their neurons fried, I'm going to suffer from it as well when they grew up as they won't be able to do their job well. If society decides that it's fair to allow CSAM everywhere, I guess that a few children are going to suffer as it becomes mainstream.

We don't live in a vacuum.

> Their ongoing tire simulation project seems even weirder and as if it was done by people who actively tried to ignore standard approaches for modeling tires.

That makes it much more valuable for me, than simply copying what everyone else is doing.

I already have basically every other sim, purchased on Steam and installed.

I can just jump into them, and for example enjoy AMS2, or LMU, or iRacing tire models instantly.

So much more. What assets/patents do they own? How much money is in the bank? What does their liability sheet look like? How “hot” is their industry right now?

Some time ago I found a good formula to plugin numbers and get a valuation multiple. The questions above were the ones that really moved the multiplier. A major lot of “startups” are in the 1-2x range. The hot ones will peak at 7-12x.

> You don’t get adult toys in your local grocery store

In the US at least the classier vibrators have been starting to be sold first at shops like Sharper Image, and now, indeed, grocery stores. The packaging of course would not raise any questions from kids, and they are sold in the same aisles as condoms and lubricant. "Sexual health" is the umbrella term which feels like it is in play.

You're the only one who asserted a percentage. So allow me to clarify, when I wrote that comment I had no belief that a law need be 100% effective for it to be a useful law. I also believe there's a lot of room between 100% effective and "backfiring". I don't believe this is a binary situation but there's a spectrum (that isn't one dimensional)

I hope with this added context that my previous comment will make much more sense and you can interpret it closer to what I intended.

I'll just add, I don't think most people work in those absolutes. So I'd be wary of jumping to the extreme interpretation. People might interpret you as being disingenuous and using the logical fallacy "logical extreme" or "reductio ad absurdum". But I'm pretty sure you're not doing that because then I'd be grossly misinterpreting you, right?

One of the less obvious benefits of teaching a mainstream language (or a "hobby" language—the kind you might pick up on the weekend for some hacking) is all the folks who don't go on to graduate with a CS degree. Will Scheme teach interesting ideas? Of course. Will someone who doesn't code for a living download a scheme compiler and write a script five years after graduating? Not a chance. Ten years? There's no universe.

Front-loading the mainstream language means you're not just teaching CS fundamentals, you're giving someone a tool that they can readily pick up and use in their real life for real tasks. It's the same as having home maintenance as a component of your basic high school shop class instead of how to rebuild a carburetor: unless you're working with carburetors for a living, that's an unlikely skill that you'd reach for. But knowing how to correctly hang a picture, replace an electrical outlet, or patch drywall is something almost anyone can put to good use ten, twenty, thirty years on.

It looks like they're pivoting into corporate finance tracking which seems like a good move but still a bit jarring as I was curious to give this a go!

> But the problem isn't porn. That's the low hanging fruit for a massive power grab

I mostly agree with this. There are legitimate issues with even the biggest and most respected porn sites being very lax with taking down underage and nonconsensual content. The card companies AFAICT aren't being pressured to reform because of this kind of content, but more the LGBT content which is harming nobody.

> Card & Kruger (1994) was a null result paper showing that increasing the minimum wage has a null effect on employment rates. This result went against the common assumption that increasing wages will decrease employment at the time.

I had to look that up, because more precisely, it showed that a particular minimum wage increase in NJ from $4.25 to $5.05 didn't increase unemployment in 410 particular fast food joints in 1989-1990 - https://davidcard.berkeley.edu/papers/njmin-aer.pdf - not that "increasing the minimum wage has a null effect on employment rates" at all, ever, no matter what. It's not as if increasing the minimum wage to something impossible to afford like $100 trillion wouldn't force everyone to get laid off, but nobody generally cares about the limiting case like that, as that's relatively unlikely.

The interesting part is non-linearity in the response, seeing where and how much employment rates might change given the magnitude of a particular minimum wage increase, what sort of profit margins the affected industries have, elasticity of the demand for labor and other adaptations by businesses in response to increases, not whether it's a thing that can happen at all.

And we're seeing a lot more such adaptions these days. There are McDonalds around here that have computers in the lobby where you input your order yourself and I've gotten drones to deliver my food instead of DoorDash drivers. That kind of thing was not yet practical back in 1989, when I remember using an Apple ][ GS and it's not clear that findings like this should be relied upon too heavily given that some of the adaptations available to businesses now were not practical back then, especially when technology may change that even more in the future.

Some of the mechanics on this one..

Generally, when a startup is acquired, people get paid in a number of tranches:

- First, debts get cleared in order according to debt types. This could be cloud providers, lawyers, employees who deferred salary, etc, etc. If there's still cash left..

- Then preferred (generally earliest) investors get paid back. Some investors will have liquidation preferences where they get 2-5X their initial investment. If there's still cash left..

- Then execs get their preferred shares cashed out. Depending on how many rounds they'd raised, they may own less than you think. If there's still cash left..

- Finally, general stockholders get paid. This is where most employees may actually get cash.

To further complicate things, some people could be in multiple places here. A founding exec may have lent the company money to get started, have preferred shares, and have common shares so they could get paid out in early levels but not at the end.

*There are WAY MORE nuances in this but the point is: You don't just say "total price divided by shares times number of shares = the cash you get"

As a previously huge Musk fanboy, I must admit that I was trying to grasp at straws at the point of TFA, and many other points prior.

At one time, I thought maybe Musk's brain was a victim of some microwave brain->mush weapon or something. Then, I thought it was all about when he went from not realizing his gains to getting the biggest single pay day in history, and having to write a multi-billion dollar tax check that fried his brain.

In the most recent years, I thought that he flipped personalities, and somehow became an easily influenced person for some reason [0], who might believe things that a person like Sacks tells him.

When he gave a Nazi salute to the world, twice... well, it doesn't matter what my theories were anymore. There is no denying exactly who he is now.

I still wonder, was he always this person? If so, top .0001% acting skills.

Interesting point, I agree that things change so fast that experience from a few months ago is out of date. I'm sceptical there has been a real step change (especially based on the snippets I see claude 4 writing in answer to questions) but it never hurts to try again.

My most recent stab at this was Claude code with 3.7, circa March this year.

To be fair though, a big part of the issue for me is that having not done the work or properly thought through how a project is structured and how the code works, it comes back to bite later. A better model doesn't change this.

Were you just not paying attention back then? The AI naysayers have been at it since at least 2012 or so when DNNs became a thing.

> "This guy is a creeper and treats romantic partners terribly" is pure opinion, and cannot be defamatory.

That is true. But i think untrained and emotionaly involved individuals will have trouble navigating the boundaries of defamation. Instead of writing opinions like “treats romantic partners terribly” they will write statements purporting facts like “this creep lured me to his house, raped me, and gave me the clap”. This is not an opinion but three individually provable statements of facts. Plus the third would be considered “defamation per se” in most jurisdictions if it were false. (The false allegation that someone has an STD is considered so loathsome that in most places the person wouldn’t need to prove damages.)

Unles specifically coached people would write this second way. Both because it is rethoricaly more powerfull, but also because they would report on their own personal experience. To be able to say “treats romantic partners terribly” they would need to canvas multiple former partners and then put their emotionaly charged stories into calm terms. That requires a lot of work. While the kind of message i’m suggesting only requires the commenter to report things they personaly know about. And in an emotionaly charged situation, like a breakup, people would be more likely to exagarate in their descriptions, making defamatory claims more likely.

> Under US law, providers are generally not liable for defamatory content generated by users…

This is true, and i believe this is the real key. Even if the commenters would be liable, the site themselves would be unlikely to become liable with them.

Should the government be able to blackmail credit card companies? Do you really think the credit card companies care where you spend your money? All they want you to do is spend more. They are trying to get out ahead of your own fellow citizens (and their government) who agree with more "censorship" and, at least in this regard, more state control. Unless you have a solution for this strain of American politics focusing on credit card companies is, in this situation, missing the point.

We’re already most of the way there. There’s the da Vinci Surgical System which has been around since the early 2000s, the Mako robot in orthopedics, ROSA for neurosurgery, and Mazor X in spinal surgery. They’re not yet “AI controlled” and require a lot of input from the surgical staff but they’ve been critical to enabling surgeries that are too precise for human hands.

> or that claim things that are per se considered damaging --- a specific and limited list

Standard disclaimer that law varies by jurisdiction. However, that limited list typically includes claims that the person committed a crime. Many juristictions also include accusing someone of having a contagious disease, engaging in sexual misconduct, or engaging is misconduct that is inconsistent with proper conduct in their profession.

In other words, the types of things I would expect people to be talking about on tea overlap heavily with defamation per-se.

If the users were careful to make all of their statements opinions, that defense would work. However, I doubt that is the case. Instead, I expect many users to include example of what their ex did that led to their opinion; which gets directly into the realm of factual statements.

The provider protections are real, and likely protect the app from direct lawsuits (or, at least from losing them), but do not protect the app's users. A few news stories about an abusive ex going after their former partner based on what they posted in the app could be enough to scare users away. You don't even need to win the lawsuit if your goal is to harass the other person.

While this rightfully exposes the games that credit card companies play for you to get your points, the real problem is that credit card rewards are yet another transfer of wealth from poor to rich, and affect everyone, even if you use cash.

https://www.federalreserve.gov/econres/feds/files/2023007pap...

> Comparing cards with and without rewards, we find that, regardless of income, sophisticated individuals profit from reward credit cards at the expense of naive consumers.

> We estimate an aggregate annual redistribution of $15 billion from less to more educated, poorer to richer, and high to low minority areas, widening existing disparities.

> Second, we contribute to the literature on reward credit cards, which has largely focused on interchange fees as a source of funding for credit card rewards. Interchange fees get passed through to merchants, which potentially respond by increasing retail prices for all consumers. Thus, credit card rewards might to some extent be funded by cash and debit card users who pay higher prices without receiving any rewards to compensate.
