""never needed refueling" Wouldn't that be fascinating?"
The act of refueling is not a problem in ICE cars. It's arguably their greatest advantage (only?) over electric ones.

" I Guess (wishful thinking maybe) that the radiations would be far less dangerous and more local than is explosion and fire from current car crashs."

And you'd be guessing wrong. A breach in the containment would be catastrophic for the whole neighborhood, if not city, for decades.

" The thing is, such experts will not read this thread " Actually nuclear experts do, sometimes, show up.

" But I want a nuclear expert to show me a calculus that would show if the dangerosity is negligible or higher (how much) than current crashs."

Buy Lamarsh's book. It has all the calculus you want. Amazon has it for less than $40. I myself have a copy in my basement and it's a good book.

" reusing the wastes or provably safe reactors which necessarily auto shutdown by design"

I don't know much about breeders ("reusing" waste reactors), but I doubt you could contain the neutrons of fast reactor.

No design is "provably" safe (this isn't 10 LOC run through Coq). The industry uses the term "inherently" safe or, better, "passively" safe. It typically refers to the reactor power naturally tending to zero if the safety mechanisms fail. If you crash into cement barrier, though, all bets are off.

""we don't have a solution for the contaminated [...] But I expect it to be trivial" and you'd be wrong. Waste management is the number one problem of the industry.

"but it was like a few kilos at most" Actually it's in the tons, you're confusing waste with mass that no longer exists as it became energy.
1Kg is the amount of mass that became energy through E=mc^2 (try it: 1GWe reactor @ 0.3% thermal efficiency running for 365243600 s = 1.05E17 Ws = m * c^2 -> m = 1 Kg)

But that's only about 0.1% of the total mass of fuel and waste... therefore tons!

" So for a micro reactor in a car it should be a few grams at most" It doesn't scale linearly.

"This already exists, but democratize very slowly due to lack of funding because of irrational politics driven by hysterical people fear "

A patronizing attitude towards people's fears mixed with general ignorance on the subject doesn't bode well.
I believe that marketing Python as "strongly typed" has the potential to confuse rather than educate. Python still crashes at runtime with these errors. It has nice error messages, but it still crashes, potentially in production. If you want to create your own "types", you'll have to add your own runtime checks. It's much more sane than JavaScript, but it's not strongly typed like Haskell. Python does not automatically coerce some built-in runtime values, that's it.

It was done in 8 years because the US was spending 4% of GDP on NASA, which was probably a mistake in retrospect. The other reason is that it was a greenfield project with competent management, generally.
Just because you have a Python function that has strict requirements for input doesn't mean every function you're writing has strict requirements.

Moreover, using a strongly typed language doesn't magically make you invulnerable to invalid input. Unit tests are useful in every language.

The problem is it's a "a privately operated citation processing center" that's causing the problem. They might even be instructed to hand-enter a NULL for these cases.

The Volt was also conceived in the late 2000s when gas prices were high. It was partially a hedge against skyrocketing gas prices. Between the first major oil price crisis in the '70s and today, people reliably buy bigger, more polluting cars when oil is cheap and smaller, less polluting cars when oil is expensive.

Fracking may have semi-permanently put a cap on the cost of oil, which is horrific from a global warming standpoint but does seem to have altered what cars most people purchase.
The code doesn't rely on a magic value, the humans have decided that an empty value will be typed, by hand, into their terminals as the characters "NULL".

The problem is that the employees with access to the system are required to enter a 'valid' value. But in some cases there is no value. So the 'valid' value they've come up with is the string "NULL" - they can't use "~~NULL~~" because ~ isn't allowed on a license plate. So because A) anyone can request a valid value on a plate, and B) nonce values must also be "valid" within the system, the tax payer is capable of ordering a nonce value on a plate.

Why do you think that Python should be compared to Fortran? Why not Rust or Julia? If we compared everything to worse humanity would not progress at all. I have spent 10 years on Python and I sympathize with some of the criticism below here pretty much. I wish Rust or Julia will replace it for data crunching soon.
Google is trying to be non-partisan, so that they can have their algorithms continue to do all of the work.

They delegate “what is true” to trusted sources rather than taking a position themselves, which is then frequently abused by wiki editors and crowd swarm attacks.

Recognizing correctness over both reputation and quality is not something an algorithm can evaluate with finality, and is an aspect of the old Yahoo! Directory that Google has never been able to replace.

Google will continue to worsen at any search for which one possible reply is snake oil, because they continue to refuse to apply human reasoning and make biased judgements for and/or against the claims of the sites they index.

This will eventually be the end of Google, but they seem unwilling to confront it.

It's not just about speed. Great mature libraries have been written in C over the decades. Rewriting them in a new language is a herculean effort. Writing bindings to them lets you use the fruit of all that labor.
This is tragic. Examine.com is probably the best site I know with a focus on determining the science behind any food or supplement one might be interested in. They should be at the top of every Google search.

> There's a very good argument to be made that Wells Fargo, who was actually one of the parties involved in the transaction is more appropriately liable...

Specifically, my argument would be that Wells Fargo was in a position to verify the criminal's claimed identity, but didn't.

I don't think this is really about liability for the direct cost of the fraudulent transaction, though.

It sounds like third parties (banks, credit providers, etc) have been libelling the reporter by claiming to other third parties (credit agencies, law enforcement, etc) that he did things that he didn't. They should be expected to verify identity more carefully before making such strong claims like that, and should be liable to the reporter for damages caused as a consequence of their negligence.

Likewise, if law enforcement has been told about the fraud, then they should be held to account for harassing this unrelated party.
mypy is a great effort, but very experimental. Try using it on any real-world large enough project and it loses most of its value as there are still a lot of unimplemented things, or because you'll depend on a third party module that hasn't support for it yet.
That link says the opposite -- that the vice premium disappears once you factor in their unusual capital structure.

> A scalar is any kind of singleton number, but it doesn’t exist in contrast to boolean values; rather, it includes them.

But this was exactly my point: scalars, regarded as 'singleton number's, don't include Booleans, because Booleans aren't numbers, singleton or otherwise. (Unless, again, you wish to regard them as belonging to the field with two elements.) Booleans can be coerced to numbers, but the way to do so, even if we agree that the two numbers are 0 and 1, is arbitrary—unless we require that certain algebraic identities hold, identities that indicate that the (usual) algebra of Booleans is not the (usual) algebra of real numbers.

It is a nitpick, to be sure; but (a) part of the point of types is to facilitate, and even automate, exactly this sort of nitpicking, and (b) it was in response to a nitpick, too.

> The notion of “fuzzy logic” is especially relevant: https://en.wikipedia.org/wiki/Fuzzy_logic

Agreed! It indicates that coercing Booleans to numbers suggests fruitful analogies, but, again, says to me that they are not actually numbers. (Once again, I point to their operators, which, from a computer-science as well as a mathematics point of view, are part of what a scalar, Boolean, or whatever is: https://en.wikipedia.org/wiki/Fuzzy_logic#Fuzzy_logic_operat... .) These indicate that perhaps one should think of Booleans as belonging to a continuum of values coming from a tropical-type structure (https://en.wikipedia.org/wiki/Tropical_geometry) rather than from a field as 'usual' scalars do.
That's not exactly true. Some fighter and fighter-trainer jets, such as the F-5 (a light supersonic fighter with some strike capability) and the T-38 (a related trainer), have multiple examples in private hands in the US right now. They are very expensive to purchase, of course, and almost as expensive to maintain - thoroughbreds are a pauper's diversion by comparison - but that's not the same as saying it is impossible to own one, and depending on the specific mark of Harrier in question, I wouldn't necessarily see it as unreasonable to believe Pepsico could fulfill that claim.
> Many European cities are quite busy banning private rentals and requiring owners to actually live in their apartments. In my country it’s even illegal for foreigners to buy vacation homes.

Those all seem like really great ideas. I wish we had anything as strong/effective as that in the US.

>A few executives and directors (who are already the richest humans that have ever lived) are adding orders of magnitude to their hoards with these massive buybacks.

First of all, it isn't "we". This is not public money. It belongs to the shareholders, and buybacks are one way to return the money (tax efficiently). Why should it be horded by the company? If there is nowhere to invest, give it back to the owners to spend or invest as they see fit. Second, buybacks don't magically raise the share price. The number of shares outstanding decreases, but so does the cash on the balance sheet.

There is plenty of literature on stock buybacks and how they work, you simply need to look beyond the populist headlines.
I mean, they ARE liable in the sense that they will have to eat the loss (the money they loaned out won't be repaid). The problem is that for them, this is just a cost of doing business, and that cost is already priced into interest rates... the cost to the person who has to prove it wasn't them has no return and is only negative
Clubhouse Dark Mode Is Here
The Strong Towns line is a pretty simple one, and this article simply reiterates on it: Nobody does ROI calculations on infrastructure costs and it will catch up with you sooner or later.

It might be compared to technical debt for the HN crowd: you build fast and break things for a couple of decades (post-WW2) and then suddenly you find yourself with an unimaginably complex, catatonic system that can't pay for itself. The interest payments overwhelm the rest of the system.

However! That doesn't actually answer the question about why _new_ infrastructure costs so much (surely a new subway line doesn't actually care if half the roads are ten years behind their maintenance schedule).
The underlying factor really is that the people in charge of spending infrastructure money are not really incentivized to be careful or ask tough questions about how it is being spent. Furthermore, they are often bound by piles of regulations and restrictions on their freedom for contracting the work, so they also lack agency.
The ones you are talking about are not "tourists" in my understanding, they are "travelers". From my experience there are way more "tourists" who just take paid bus rides, eat "restaurant local" and stay at the "5 star local".

They are there to see, and make a tick in their mind. They are not even interested in talking. Tourism is not a small industry - we are talking about hundreds of million people globally. A tiny fraction is actually deeply interested in the culture.

I own a rare collector car with a three-digit VIN. This has caused endless hassles at the DMV as well as the insurance office.
Sometimes we find success by prepending the necessary number of zeros, before the VIN. Other instances in the same system require appending zeros after the VIN. The true VIN has a hyphen but that never makes it into the DMV's system. One time I got stuck in a particularly nasty loop where the DMV mailed over thirty notices claiming the register would expire on 01/01/0000.
What kind of eggs do you use? Regardless of your opinions on animal rights, etc, I strongly recommend buying the fanciest free-range, etc. eggs you can find. A healthy diet for the chickens makes a huge impact on egg quality & taste. I doubt this will solve your entire problem, but it helps.

I assume you're already using fresh garlic & onions, but those are also musts in my opinion.
There are multiple reasons why strong opinions exist.

But at least one of them is quite valid. We have a lot of garbage in our industry. People perceive that correctly and call it out. Simple as that.
May be because they can't compete with Toyota, Honda, and now Hyundai on Hybrid vehicles. It's too late to invest in hybrids for them. They can only compete in full EV's as most companies don't have a solid product yet.

Fuel is a huge airline expense so people are packed into an aluminum can at maximum density. It's public transit, except the seats are nearly full at every stop.

Fuel economy is about 75 mpg per passenger. This is nearly twice the average mileage as busses, and better than nearly any other realistic form of travel https://afdc.energy.gov/data/mobile/10311

(Other sources give 75mpg for airline average but this may be for a full plane)

It's a huge misconception that flying is a wasteful means of travel. It's practically the most efficient means there is
They're likely different organizations. The one that entered 'NULL' license plates was a "privately operated citation processing center" so they presumably weren't in charge of looking up the addresses for each license plate. If they were it would be rather pointless to save the 'NULL' value in the first place.
Which is why some of my coworkers simply won't do it.
Toxic masculinity does discuss a facet of our society that should absolutely be discussed, but I think part of the issue with the term is that its phrasing is unproductively antagonistic. It's like talking about neurotic femininity or violent blacks. While there is something real and interesting to be to discussed about those real social issues, the phrasing frames the conversation in an unhelpful and mildly accusatory manner that is not conducive to a productive conversation.
What's wrong with chaining try/except?
I doubt it's about backing beliefs and principles with money. It's probably more about admitting increased risks of losing money as a result of public shaming campaigns (sometimes reasonable, sometimes not) by vocal minority.

And of course, the corporate PR disguises such dumping stocks as a virtue.
> That's $160M in revenue, but with $30m in costs. Profit to cost ratio of 5:1.

This doesn't consider the immense second order effects of releasing an expansion. Releasing a new expansion maintains and increases player engagement - i.e. monthly subscription fees. Without new expansions to keep the player base engaged, players won't purchase cosmetic additions like mounts.
Unsustainability is unsustainability. At the scale of climate change it's no longer "we'll prosper at the cost of others", it's "we'll prosper in the short term at the cost of everyone - including ourselves - in the long-term". Finance people are apparently better than executives at thinking long-term (or maybe just have more incentives to care about the long-term, whereas CEOs can generate some quick growth and then peace-out).

Reminds me of a recent groceries delivery to my home. I had ordered online the day before and had some trouble filling in the form but managed to validate it anyway.

There is a wide spectrum of the amount of time, effort, and money it takes to learn various skills. This seems like a celebration of those skills on the small end of the spectrum that anyone can learn, whether they are practical or not.

Ontario Canada has an anesthesiologist with a “FENTANYL” license plate.

Was funny in 1995, not so much now.

So he went to the DMV and asked them to change it, and they wanted to charge him to do that.

He’s like, no, i’m not paying.

Eventually he writes a letter to his politician saying “please revoke my license plate” and eventually he gets a letter saying they got a complaint (ie: his) and the DMV wants to revoke his plate.

But he had to wait 30 days For the appeal clock to run out, just in case he wanted to appeal his own complaint.

Kinda funny, but kinda sad that someone paid $400k+ per year by the government wasted thousands more because he didn’t want to pay the $100 plate change fee.

Soooort of, but not really - at least for the ones I've seen. There's a difference between "finish an 80% lower" and "make a gun from blocks of metal", and I think we'll hit the latter relatively soon.
That $1B number gets some real doubt from me. I'd bet the real number is a few $100M lower. No way rockstar had over 1k people working on that rd2 for eight years at ~$100k avg.

Almost certainly because of software constraints, like the form not allowing the plate number field to be blank.

> everyone has inherent rights and no one is above the law

I don't see how these are "democratic values". They're extremely important things to have obviously, but they're orthogonal to whether the system is democratic or not.
Right, it's privatized profits from having a cheaper insecure system with lower sign-up friction, and socialized losses because uninvolved third parties and law enforcement have to pick up the pieces and find the guy to make an example of.
Hopefully not as the "Volt". It's a shame the car didn't work out, but the Bolt/Volt naming thing was a source of endless confusion.
Airplanes produce more greenhouse gas emissions per km than other travel methods. Over a nominal 1100 km, a generic passenger liner will produce 0.17 metric ton, whilst trains contribute a quarter to less than a tenth that, and coach buses a fifth. The same distance would be like driving a petrol car averaging about 36 US mpg or 6.5 L/100 km -- but your family of 4, let's say, would split that emissions impact in the car, where in the airplane it'd be 4x.

The notion that jetsetting should be a right of the masses is a myth built on future generations paying for the damage mass flying does today. Thinking ubiquitous travel should be cheap and trivially available may actually be the elitist view, as the elite or wealthy will be the only ones able to protect their way of life as the natural environment changes and cities become more difficult to live or work in.

>Well, it worked on Star Trek. Then again, that was addressed in a Voyager episode when Tom Paris designs the helm in their new runabout with old fashioned buttons and switches because he wanted to actually feel the controls much to Tuvok's dismay.

I didn't watch Voyager much, and never saw that episode, but this is extremely disappointing. The ST:TNG Technical Manual (which came out before VOY) clearly addressed this issue, way way back in the early 90s. You can actually feel touchscreen controls, because they have miniature force fields/tractor beams that provide the same tactile sensation you get with mechanical controls. Didn't the writers of VOY ever read the TNG Tech Manual?

It's of course even more disappointing that a sci-fi TV show in the 80s/90s was able to address this important HMI issue in a book meant just for geeky fans, yet 25 years later people in the industry still don't get it. Of course, we don't have tractor beams or force fields to implement what they wrote about in the tech manual, but it does show the show's technical consultants were thinking about and aware of this issue back then, 15 years before slate-style smartphones were even invented, and that maybe we should not be using touchscreens for certain controls until we do have force fields or some other workaround.

>and I mean HATED the touch screen when it came to virtual potentiometers (one operator got up and walked away saying "this screen is a fucking piece of shit")

That operator was correct. Virtual potentiometers on a touchscreen are a horrible idea and miserable to use.
Disappointing. :(
