> "the amount of power lines needed would be quite astounding; say - 30A at 230V (or 3x 16A for 3 phase) per parking slot."

Not really, because not all parking spots would be charging at full capacity simultaneously. For that reason you can have a lot more charging-enabled parking spots than you have electrical supply for: in the event of unusually high demand, the outlets can throttle themselves to ensure that breakers aren't tripped, etc.

Norway has some experience building these sorts of facilities already:

> "Last summer my family took a trip through Europe (central/west), often driving 600-800km a day. The range would have not been sufficient"

That's where high speed charging comes in. The new charging networks currently being built by Ionity (in Europe) and Electrify America, for example, are capable of 150-350kW charging. At those speeds, you only need one charging stop - of under 30 minutes - to complete that 600-800km day of driving.

We've all got to eat and take toilet breaks, so few people would drive that far without stopping even if they could!
This isn't about deflationary vs inflationary money, because you can encode any type of currency policy.

Instead it's about no single entity can suddenly decide "let's issue trillions of dollars to repay our debt!", which erodes any savings you have and can in the worst case collapse the economy (see hyperinflation).

What I guess you're after is having the ability to respond to the economic climate by stimulating the economy? Then let me introduce you to the concept of sound money and what Austrian economists have to say about it.[1]

The basic point is it's impossible for a single actor to predict the market behavior, it's why a planned economy doesn't work, because the market consists of actors who only act in their own best interest and don't have perfect knowledge.

Edit: It is indeed possible to change the currency policy... If the community agrees, which is a very tall order.
Cash payment is an obvious counter-example. Yes, the seller needs to keep records for tax purposes. But the buyer does not.

I think it’s just that people have strong opinions about the tools they use, and that network effects in programming make people fear that other people’s choices will be foisted upon them.

Programmers have a strong desire to make things as ideally correct as possible, and that extends to technology choices (perhaps such choices are foundational) and so it can be an affront to one’s sensibilities to see the “wrong” choices being made.

But ultimately we all have different value systems and experiences. What works for us, and more importantly what appears important to us, may be different to others. But that is okay.

My take is that there’s a lot of space for experimentation with different ideas in languages and general approaches to building software. It’s still a very young field. We should keep pursuing lots of different ideas, old and new.

I will answer the question that is always asked in every post regarding blockchains on HN:

"Why blockchain? Can't this be done with a database?"

Blockchains are databases. They are distributed, append-only, tamper-proof databases. You could call them that, or instead you could just say "blockchain" as that is what type of database the word blockchain has come to be understood as.

The reason to use a blockchain rather than a centralized database is because the properties described - distributed and tamper-proof - are crucial to the application. In Libra's case, centralized entities that control financial services (banks) have high fees, are slow, and are not trusted in some respects (financial bailout) while being highly trusted in others (not waking up and losing your money). A blockchain can provide solutions to the problems of centralized financial entities with the benefits of distributed ones.

Well, Erlang-like actor model is one basic pattern for achieving safe concurrency. A second one is keeping data read-only so that it can be freely accessed by multiple threads; and a further pattern is serializing access at run time (either using explicit locks, or in special cases with "non-blocking" algorithms and data structures). Rust is pretty unique in being able to comfortably encompass all of these patterns in its concurrency model, while ensuring safety.
"It's opinion. That's my point. Nothing more."

My point is that the opinion of the US Supreme Court has far more of an impact than simply saying it's an opinion.

"When the government has control over access to information or channels to information, they get to manipulate the flow of info."

And when private industry has control over access it's better?

In any case, I am describing what we have now, with public service and private services. The private services are able to use the public information, and add their own observations, modeling, etc.

I can't think of any system which could prevent your (IMHO movie) scenarios. I mean, in real cases where secret planes crash and parts are everywhere, they don't do that now. And it seems pointless as most people don't drive/navigate that way.

> Renewable energy sources needs to be supported by power plants that can produce constantly.

Do you have a source for that claim? Keep in mind that there are also renewable energy sources that do not rely on weather events (water and biomass).

In combination with energy storing and a reduction of the total energy needed it is afaik considered possible to go fully renewable [1].

[1] https://en.wikipedia.org/wiki/100%25_renewable_energy

EDIT: I misread your comment. I thought you were arguing that "unclean" power plants are nessecary. However my point about not needing nuclear still stands.
Yes, I'm sure you're aware. But the way your comments are written are pretty misleading, so I'm trying to clarify them. If you don't think the clarifications are beneficial to you, then treat them as clarifications for anyone else who is reading.

> Anyone who doesn't understand why that's potentially unsafe wouldn't be ready for Rust in any case.

That's most certainly not true. They might not be ready to write high performance generic data structures from scratch, but application level code in Rust generally has about as much explicit `unsafe` as application level Go code, in my experience. (And writing high performance generic data structures isn't really a thing in Go. Not nearly as much as in Rust anyway.)

I would agree that Go is rarely the best choice for particular problem, but I've found it to be a good choice for "enterprise development" for two reasons. It's easily reviewable by others with varying levels of skill and familiarity with the project, and it doesn't have a complicated deployment story.

At work, I've seen Go used primarily in projects that would have previously been written in Python or Ruby.
Note that in small print that table assumes 500g/kWh which is _very high_. If your electrical grid was entirely supplied by mediocre natural gas power plants (no hydro, no nuclear, no solar, no wind, nothing like that) you'd do 500g/kWh. Anywhere doing worse than that is burning coal, or as in Ireland, peat to make power, which is totally crazy independent of whether you have electric cars.

Put a bunch of hydro, nukes, solar or wind in the mix and you're rapidly down to 200 or 300 gCO2/kWh. Nobody's ambition for 2030 ought to be as high as 500 gCO2/kWh electricity, if that's what you're expecting we're screwed.

My in-laws recently downsized to a townhouse and needed to get rid of some books, so I ended up with about 20 Jack Reacher (and similar) books. I grab one whenever we head out on vacation.

They're great, because there's no need to read them in order, or remember previous plots. They're good enough to keep my attention but not so great I can't put them down when it's time to do something else.

I don't know how they thread that needle so well, but they do. I expect when AI write the first decent book, this is what it will look like.
>There are plenty of affordable new cars, they might be small and slow

Define affordable, because I'm never going to spend more than €2000 on a car so at the moment drive a small-ish but slow 1.6L petrol car from 2004.

At least it was the smallest I could get away with while having to fit 190cm skis in the car everyday.

I can't wait to go electric, but I think I'm 10 years away from being there myself. Also moving between rented accommodation in rural areas often with only street parking makes the whole "charging at home" thing quite a pain. I'm hoping by then things are better, but in the countryside I still think electric cars are going to be a tricky thing to migrate to.

From what I understand there is no Rust being used internally at Google (apart from perhaps individual engineers tinkering with it just for fun).

There is no support for it from the build tools, so anything more than just messing about on your own machine won't work at Google: no libraries, no way to compile it, no way to test it, no way to deploy it, and no way to monitor it.

Anyway, the processors in the F-22A are a mix of different cores. The power supply in the Gen 3 radar used a MIL-STD-1750A processor. The PICC[1] processor modules also used the MIL-STD-1750A originally, but moved to a newer processor in a refresh (if I remember correctly). I don't know what the non-Raytheon components of the plane were using.

As for the compiler, you are spot-on. We had a MicroVAX in a vault (it was a cleared computing system) just in case we needed to recompile the embedded software for the power supply controller.

Related to that, I highly recommend Factfulness[1]. You can try to answer 13 a/b/c questions here[2]. Most educated people score lower than if they would have just chosen answers randomly. It's really hard to discuss population and poverty if most people worldview is so skewed.

Btw, I've been wondering how population stabilization (it pretty much already stabilized in the US and EU) will influence real estate. Historically real estate have been a remarkably good investment. But historically population kept growing pretty fast. I'd love to hear some thoughts or recommended reading on that topic.

I’m sure 99% or more of muscles and bones are shared across the various dog breeds but humans have about as much genetic diversity as the average chimpanzee troupe and we have differences in our musculature. For dogs to be more uniform than humans given the speed and vigour of selection seems unlikely. Some breeds should lack vestigial muscles and others have them by more or less random chance.

Thanks! Here are some reasons why I think it is worth picking up even if you've read a lot on mental models already:

* The mental model community likes to quote Charlie Munger saying "80 or 90 important models will carry about 90% of the freight in making you a worldly-wise person" and yet no one tries to systematically lists out all these models. This book attempts to do that.

* We spent most of our time finding relatable examples outside the discipline in which a given mental model arises, which is why they are supposed to be useful. That is, we don't just tell you what it is, we try to tell you why it is generally useful in strategic decision making and how you might apply it personally and professionally.

* We dropped the normal method of grouping models by discipline, and instead grouped them by theme, weaving models from different disciplines together around unintended consequences, decision models, etc. (nine chapters).

* We commissioned and/or found illustrations/comics (150+ in total) to help better explain and remember the models, as well as make it more fun to consume!
Trading cattle is my way to go but I have to say that I'm getting sick of all the chickens I get back as change.
This is exactly my experience.

I've used C (closer to Go than Rust) and I've used C++ (closer to Rust than Go) in previous jobs. My experience is that the C programmers tend to focus on the problem at hand. On C++ teams, people spend a lot of time going to C++ conferences and discussing the idiomatic approach to mundane tasks in their superior language. I imagine we'll see the same thing happen in Go and Rust... different personalities are drawn to the different languages.

I'd rather be going to security, networking and crypto conferences instead of wasting a lot of time on a particular language.

It can be found in many libraries in the ecosystem, and is common enough in the standard library.

The lack of generics just severely restricts the expressiveness of the type system.

I think the best way to work around this is use of code generation, which is a great tool for internal, controlled environments, but very cumbersome for open source libraries.
