How does that work, though? Aren't highways crazy expensive?

In what world can 2 metal tracks plus some small foundations be cheaper than 20m width of concrete, asphalt and much bigger foundations?

The economics of rail versus roads don't make any sense to me.

The only way they do, I imagine, is if roads are crazily subsidized.
With better last mile connectivity, trains should be the only option. But guess loading and unloading is the weak link along with last mile lack of options.
A very reasonable perspective, thank you!
Given that Tesla tried battery swaps and canned it, and that venture funded startups already burned a billion dollars trying it and failing, I don't think many companies are eager to repeat the experiment.
Actually, that is one of the Wasm key features: being a platform-independent binary not tied to any specific HW architecture.

Translating x86_64 code to arm64 requires more CPU cycles than JITting Wasm into arm64 or x86_64.

Buy even more: in the use case covered in this article, the PHP interpreter won't change so it can be AoT compiled upon deployment to the target architecture. No JIT compilation needed :-)
One could use js to push the state into the url.
Geez. Techies trying to come up with tech solutions to fundamentally non-tech problems. The photogtapher can just zoom in or get closer to the object to crop the image before it's even taken.

Oh you now want a 360 degree shot to prove this didn't happen? Well then they stand behind a tree or a car or some other object to hide parts of the scene behind. etc. etc. There is no technical solution to this problem.
> I also really liked the idea, but some specialists have argued it would be hard to provide rigidity.

Do you happen to have any pointers to more info on this? I don't understand what would prevent the industry from standardizing on a structural battery pack rigid enough for the use case.
Is it "more than 17 features" or more "features than C++17"? For a programmer your way of formulating questions is a strange one.
> I doubt x86 will double its cache-line size any time soon

Well, why not? They doubled it from 32B to 64B between the Pentium III and Pentium IV.
The idea of a logically non-reversible, physically reversible process blows my (admittedly layman) mind. But, the paper Wikipedia linked to on that topic was around 100 pages, so any understanding will have to wait…
Looking "young" past a certain age just looks weird and creepy anyway.

Or maybe their plans is to get the first mover advantage and see what pans out ? Or get the whole market à la Uber by spending a lot of VC money and then figure out how to recoup ? See farming tech.

I used to be okay eating chicken (and beef) because I was like, they're dumb birds and don't have any real meaningful life experience. Then I saw this youtube documentary about two kestrels starting a "family" (along with his owl one) and it completely changed my mind:

https://www.youtube.com/watch?v=9kQb-badp1s

He doesn't mention anything about vegetarianism, I made my own connection there. But even something as dumb as birds have connections to one another, they have a mating and courtship process that feels very similar to humans, they care about their young and will defend them to the death, and the male partner understands the importance of providing for his mate and younglings and does so both by finding and building a nest, but also tirelessly providing food for months
The issue isn't that you're afraid of getting married, it's that you're so fixated on lumping together entire 50% of the population into a bucket that you don't realize you don't marry an entire gender, you marry an individual. If you aren't able to get to the point with a potential spouse that you view them as unique and special to you and worthy of trust regardless of what demographic groups they happen to be a member of, then they deserve to be with someone else. This doesn't just apply in one direction; a man shouldn't be viewed as indistinguishable from other men to their prospective spouse, and if they are, they deserve someone else too.
I asked GPT-4 to calculate the energy density required for a Ford F-150 Lightning to weigh the same as its gas counterpart. Seems about right to me.

> The Ford F-150 gas version has a gross weight of 6,470 lbs (2,934 kg)【14†source】, while the Ford F-150 Lightning EV has a gross weight of 8,250 lbs (3,742 kg)【25†source】. This means the EV version is 1,780 lbs (807 kg) heavier than the gas version.

To calculate the required pack density and cell density for the EV to weigh the same as a combustion vehicle, we need to know the weight of the battery pack in the EV. Unfortunately, that information is not directly available. However, we can make some educated estimates based on the battery's energy capacity and typical energy density values for EV batteries.

The battery capacity of the Ford F-150 Lightning EV is 98 kWh【21†source】. As of 2021, the energy density of commercial lithium-ion batteries (the type typically used in EVs) is approximately 250 Wh/kg. Assuming this value, the weight of the battery in the EV would be approximately:

98,000 Wh / 250 Wh/kg = 392 kg

However, this estimate is for the cells alone and does not account for the additional weight of the battery pack structure, cooling systems, and other components, which can add significant weight. For example, for the Tesla Model S, the battery pack weight is about 1.4 times the cell weight. If we assume a similar ratio for the Ford F-150 Lightning, the total battery pack weight would be approximately:

392 kg * 1.4 = 549 kg

Given this estimate, the battery pack represents a significant portion of the additional weight in the Ford F-150 Lightning EV compared to the gas version.

To make the EV weigh the same as the gas version, the battery pack would need to weigh 807 kg - 549 kg = 258 kg less. This could be achieved by improving the energy density of the battery cells, reducing the weight of the battery pack structure and other components, or some combination of the two.

If we assume that the weight of the battery pack structure and other components cannot be significantly reduced, then the required improvement in cell energy density would be:

Current cell weight: 392 kg
Required cell weight: 392 kg - 258 kg = 134 kg
Required cell energy density: 98,000 Wh / 134 kg = 731 Wh/kg

This would be nearly a three-fold increase over the assumed current energy density of 250 Wh/kg.

Please note that these are rough estimates and the actual values may vary based on the specific design and construction of the vehicle and battery pack. Additionally, increasing the energy density of battery cells is a major area of research and development in the field of battery technology, and significant improvements may be possible in the future.
4031 what?
And yet the context was:

Which I would assume that the PepsiCo product is about as heavy and dense as you could expect in normal freight scenarios, being liquids.
Interesting idea. Likely complex to solve for the various accessibility issues introduced from floor placement.
An operator ending up with all 500 plays as non paying is not breaking the law, they are just incredibly unlucky. The spins are independent, and no amount of waiting for a machine to be "due" is going to do anything.
Electric engine performance drop at low temperatures is less steep than for gas engines. It’s just that people generally don’t monitor it for ICE: you have to fill up more often, but individual drivers don’t realize it. Managed fleets do, though but they don’t mind because that usually matches the Christmas season.
Highways don't turn a profit. Why should trains?
Yes but it’s not a big issue, EV owners should already carry a charging cable inside the car for safety.
That method works well for initially building the system too. Start in the db and model the relationships and then move up.
I don't know enough about CPU design to say really but Pentium IV is a long time ago now. And since then, I suspect that a lot of assumptions about 64B line sizes have been baked in.

Apple could go to 128 because they were rolling out a whole new ISA, so were breaking compat anyways.

That said, they have amazing performance on the M1, and I wonder how much of that has to do with the wider L1 size.
> Maybe slow CSS, if there's such thing?

That can definitely be a thing. However JS is usually a much bigger issue.
“was not paying attention and nothing to do with their intelligence”

You might be surprised to learn that people with an iq of 80 have a hard time paying attention to much of anything.

My point was not to quibble over the likelihood of a classroom of 150’s, but to illustrate a point, that what counts as a dumb question is largely a function of the average cognitive capacity of the reference group. You may disagree and find context doesn’t matter, and to some extent I can see where you are coming from: mistakes like not paying attention seem to be results of a slightly different thing than pure g intelligence. I see that, but suspect the correlation is so high that the distinction matters only a little.
That's before even considering topical application through the gums
Hey rust - check it out. Compile time evaluation without macros, isn’t that neat?
Have you checked electricity prices in the last 10 years ? Or just say, 1 year ?

That's volatility

A lot of energy prices are linked together, by the way, because many countries use one to produce the other (burn coal or oil to produce electricity, for instance)
Yes, and music and all other parts of culture too: the lone genius model of human achievement, suffering=greatness, the primacy of emotion, and many other tropes that are now our cultural “defaults”. It’s hard to see clearly because we’re still inside the romantic movement.
As long as the packs can be taken out of the vehicle without damaging either and the packs don't have DRM crap, packs can trivially be re-used by attaching them to a charge controller.
Yes. Humanity has been living on credit essentially for the last century through cheap fossil fuels. No one likes having to pay true costs for what they want. We’ll innovate (as we’ve clearly done with renewables, storage, and heat pumps to name a few tech) and grit our teeth in equal measures as we unfuck our enegy systems. What’s the alternative? Not? I admit it is an inconvenient truth. But the bill has come due.

If the poor cannot afford the transition, fix this with policy. We have the aggregate system wealth. Allocate accordingly.
The deregulation that enables this kind of public beta testing only works if we also don’t accept commanders with the individual power to make trade off decisions like this for thousands of workers to follow.

Time and again workers show more humane decision making given the agency in events like these or the train operators who raised warnings ahead of recent disasters etc. And we see the state siding their support with those owners over the powerless operators, which I point out to show there is value in deregulation regardless. Workers often show pride in what they do, can enjoy the productivity and value what they achieve as a group, but their limited agency at the altar of command prevents common humane reasonableness day to day and in bigger ways.
Chargers that pop out of the curb. Yes please.

Here in DC we have a lot of food trucks, and their fumes and noise is a sad mark upon the area. I dream of a law where these things could be connected to the grid instead. Right now that's just a fantasy as there's not a real way to accomplish that objective, but tech like this is exactly what it would take! And more inverters setup to be powered off EV voltage levels.
You are arguing against coal power plants. No one is disagreeing with you there.
THIS. "You don't stop saying something needs to be fixed just because it's been said before. You keep saying it until it's fixed." 100%
> I sometimes wish why can't we unbundle these left vs right issues and decide stuff case by case.

That's the opposite of what we should do. If you do case by case then people will always find reasons why it's no big deal if "their" side did it while it's really bad when the other side did it.

No, we need to universally condemn this. No matter who did it and when and how. This is lying and propaganda, and it's bad even if I agree with the ends. But the means are to be condemned by everybody.

Kind of the dual to "I disagree with what you are saying but I'll fight for your right to say it." It's now "I agree with what you are trying to achieve but I'll fight against the way in which you are trying to achieve it."
It really isn't. There are all kinds of valid reasons to get divorced, from partners maturing in different directions, to one partner maturing while the other doesn't, to drug and alcohol additions, to emotional and physical abuse.

There are also selfish reasons, including boredom, finding more excitement - but not more depth - with someone else, and festering undiscussed resentment that financial and/or sexual expectations aren't being met.

If one person goes down one of those paths and refuses to even discuss it, there's not much the other person can do.

It's immature to expect a perfect glowing zero-conflict happy ever after. But it's equally immature to stay committed to something that is clearly dead and may be actively harmful to either or both partners - and perhaps the kids too, if there are any.
Only 19% of electricity generated today in the US is from coal, trending toward 0. Then consider larger fossil fuel power plants are far more efficient than the tiny engines in vehicles.

"Coal is used to power electric vehicles," is an argument that is more noise than signal.
Do the people at the top care if the population can make 400 widgets, or that they maintain their status?
This situation happened already with vehicles. California used to get special cars because of their strict emissions regulations. Now every car has "50 state legal" emissions because A) more states signed onto the California standards, B) it was cheaper to build one vehicle to the strictest standards than to make two for a single market.

What's the point in running a diesel semi when it can't be used to make deliveries to key states in the country? That will force a "relay" model in the freight industry which kills point-to-point delivery, where diesels deliver to a border state and an EV semis runs the last leg. Once that happens, then it becomes economical to run more EV semis between diesel relays, or add rail depots to the relays for ultra-low cost transport over long distances, then EVs for the last leg.

The diesel truck industry is going to die slowly, then all at once.
It has been released 13 years ago.

Unreal Engine isn't an option if open sourcing it again was a goal and/or a means to attract new developers after the death of half of the previous core team.

Old engine foundations doesn't necessarily mean a bad thing : for instance the Spring engine was started in the late 90s, released in 2005, and not only is still used today, the fork of it that is even more successful (and with the fanciest looking games, and the best performance) today, Recoil, is the one that decided to stick with legacy OpenGL3 features rather than radically change to better fit with how OpenGL4 does things(?), in order to not break games !

Is that really possible? I don't understand the field exactly but at least if you use deep learning, you'll be able to recover inputs from gradients, and if you want to program it such that no other party is able to recover your inputs, that's called cryptography and homomorphic encryption is FAR from practical yet (like a million times slower than practical). Without rigid mathematical foundations, I would doubt that it's just a fancy way of gathering all the training data and doing the training and making it perceive as if everyone retained their own data.
> So they must have some plan for overcoming these hurdles.

Aren't a lot of countries basically forcing companies to do this early before the support infrastructure is in place?

I'm still curious how people living in the mountain of condo buildings in most major cities are going to charge their consumer cars, without having to line up for hours at gas-station style charging stations, considering most condo parking garages I've seen only have 3-4 charging spots.

Solving it for trucks delivering to various locations across non-urban areas seems a bit easier, given it's less of a real estate problem, but still a huge investment.

I'm guessing loading docks at warehouses will need to set up individual plugs while it loads/unloads and pre-planned trucks stops all along the highways? Any time they eat/rest will be designed around charging.
Needs more pop ups but well done.
this is where the midwit meme comes in. NOooooooo it's not out of thin air don't you understand?!?!
China is doing it. The key thing is you need more than just a billion dollars, you need a dozen times that (or more, but the CCP doesn't need to worry about money) and credible political commitment that customers won't be left stuck with useless cars down the road.

> For each incident there are key points for the "technical review". The employees who enter this review into the system regularly make it clear that the report is intended for "internal use only". Each entry also contains the note in bold type that information, if at all, may only be passed on "VERBALLY to the customer".

> "Do not copy the report below into an email, text message or leave it in a voicemail to the customer," it continues. Vehicle data should also not be released without permission. If, despite the advice, "a legal involvement cannot be prevented", this must be recorded.

> Customers that Handelsblatt spoke to have the impression that Tesla employees avoid written communication. "They never sent emails, everything was always oral," says the doctor from California, whose Tesla said it accelerated on its own in the fall of 2021 and crashed into two concrete pillars.
C++20 has consteval and constinit to fix this (at the cost of making things even more complicated).
It's just opening and closing detail panes (personal recipie site), there's no reason to put the open/closed state in the url.

But if I can do it with all html, that's better than a function to add / remove a css class and document.onclick = a function to find which recipie you clicked on and adjust the css class.

One thing to keep in mind is that in a lot of old houses, the top story was unfinished attic. It wasn’t livable space because it was too hot in the summer. Your 3rd story was probably like that.

My second story in craftsman bungalow wasn’t finished until the 70s. And that is probably when the window AC was put in that makes it usable in summer. The first story has lots of windows for cross breeze and stays nice in summer.

One of the very early versions of Word Perfect. I was typing some word that had "lm" in the middle of it (I don't remember which word it was). So I typed an "l", and that was fine. Then I typed an "m", and got another "l". I noticed this immediately - before I let up the "m" key. So I held it down, and I got a string of "l"s. I let it up, and all the "l"s (except the first one) turned into "m"s.

I promise that I was stone-cold sober when this happened, and I do not hallucinate (so far as I know).
Thanks a million for the encouragement! I really appreciate your uplifting words.

There's been a few stories over the years that show Tesla is a bit "laissez faire" with their security and data protection. A recap from my own memory:

1. Engineer sharing how they SSH into moving cars in order to apply updates and troubleshoot (several years back)

2. Recent leaks of customer recordings.

The whole autopilot situation is concerning too.
Teslas are great cars that just make driving a pleasure. I’m sure for every large sample of any item, there will be some problem ones. It is specifically in these cases, a non trivial number of them are not being handled with more care, more like google customer service.
I’m sure a significant part of this is growing pains, scheduling delays in service.

I would love for a singular place on the internet where people can start reporting public data about their experiences, in hopes to get more attention to these problems, at least the more common ones.
Heh, forgive me if I find the metaphor of “let’s send all of humanity into a black hole because it might be great” less than comforting.

I think the most likely scenario where we make something much smarter than us is bad. I don’t agree with all of what Yudkowsky says, but “Nature is allowed to kill you” is something that I think not a lot of people grasp on a real intuitive level. We are totally allowed to invent technology that gets out of control and kills us all. It could have happened with climate change if the earth had stronger feedback. We’ve been lucky so far, but as humanity gains power, we need a corresponding increase in our ability to coordinate and be careful to match.
> There is no moral imperative, outside of general moral prohibitions that guide you to do your best to avoid killing the same species.

We don't want our future AI overlords to kill us because we're 1000x dumber than them and also not the same species. I think it's only fair for us to extend the same morals to animals.

Precisely. The “made in rust“ tagline might sound cliché, but when the tools are as good as these ones I start to pay attention!
Mostly makes sense to me: constexpr means the function is evaluatable at compile-time, being callable at runtime is part of the contract and why adding constexpr does not change the API.

For an assertion that something is evaluated at compile time I’d assume a variable-level annotation (in a non-constexpr function). Though I don’t know c++ enough to have any idea whether that’s the case.

And contant evaluation optimisation has always been a thing so it’s not really surprising.
