IMO the reason C++ isn't a general purpose programming language is due to memory management. Many many many applications can be built without having to worry about the garbage collector and the productivity gains of using a GC language is so so worth it. And I know you can force C++ into acting like a GC language, but why go through the effort? C++ is a precision tool for building complex and performant systems and that is nothing to be ashamed of, but it is not something you would use for web api's, or a quick script, or UI's or any quick and dirty project. I also feel like the rust community is forcing the language into places where it shouldn't really be. But yeah - people can argue about what general purpose means to them, just my 2c.

Nvidia GPU's are really your only choice. There is no framework as mature as CUDA and nvidia has been making the fastest hardware for decades. They know their stuff when it comes to architecture, so its unlikely that the hot new thing will actually be able to compete.

But we are not haggling over the price. apple has control over an enormous portion of the market. I can't haggle because the big guy controls everything.

And saying apples cut pays for more services is just hilarious. we are forced to use those services and forced to pay for them. Stripe does refunds and fraud detection. There are other app development platforms for API's like kotlin and flutter.

And you and I both know that apple's margins on the app store is a joke. Thats why they dont report it seperatly in their financials. Whether epic couldnt make it is their problem.

5% Royalty past $1m for using the most high tech game engine in the world is a totally reasonable price. Just like 3% for using payment services is totally reasonable. But 30% for using a distribution service is just absurd. The only reason the app stores can charge that much is because of their iron grip on the platforms.

> Having users pay recurring would also incentivize car makers to keep investing in updating their software...

Please no. I don't want fancy software that hides essential features 4 layers deep and stops working when the internet is bad and the billing service can't be reached. I want buttons for the features and a display that works with android auto. Nothing more, nothing less.

Repairing electronics is not fun. Ask any undergraduate that spent hours looking for broken op-amps and bad solder joints. I don't think its the same class of repairability as old cars.

When solving for the wave equation, the substitution made for J is sigma * E. So defined in terms of the E field and some conductivity constant. When solving the wave equation, there is no mention of charge density, everything is fields. This predicted the existence of electromagnetic waves. In reality, we know there is only electrons and photons. So thus the wave equation is the source of truth and what we call fields are just a consequence of the complex interactions between electrons and photons and this is studied in quantum electrodynamics.

Unfortunately the explanation to your question is something that takes years of education to understand and even then, most people just come out understanding some parts. The best I can do on an internet forum is tell you that the analogy is wrong, because experiments told us its wrong. My advice is if you want to understand this stuff, do the math! ;)

The problem with this analogy is that pressure waves can only travel in a medium. The pressure wave exists because the particles in the medium bump against eachother to propagate energy so the analogy gives people the impression that electrons are bumping against eachother to propagate energy. Photons are distinct entities that can travel without a medium. See michelson-morley experiment. Electricity is nothing like what we experience on our macro scale. Analogies never convey the full story.

> Canonically, electric current results from the collective movement of electrons, each carrying one indivisible chunk of electric charge. But the dead steadiness of Chen’s current implied that it wasn’t made of units at all. It was like finding a liquid that somehow lacked individually recognizable molecules

In maxwell's equations, current density J is defined in terms of the E-field. When talking about electricity, people make the typical quantum mechanical wave-particle mistake. Electricity refers to two things, photons and electrons and how they interact with eachother. Both act as wave-particles, but photons act more like waves and electrons more like particles. The thing that gets people is that photons are the things that move energy around. A photon is an electromagnetic wave. In a wire, you can have an electromagnetic wave traversing the wire at some proportion of the speed of light, while the electrons are moving at speeds closer to meters per second. We defined current to be proportional to the E-field (because that is what is moving the energy) and thus we shouldn't refer to the movement of electrons as current.

> Additionally, saying that children and adults should be wholly responsible for this is like saying the Chinese and not the British should be responsible for their opium addiction (see Opium War) and that homeless in San Francisco should be responsible for their Fentanyl addition. They can always just say no, right?

This is why I find it funny that FAANG people call themselves software engineers. In the real world, an engineer is wholly responsible for the projects they bring into the world. Imagine a bridge collapses and someone dies. Then in court the family is told that the person was responsable to research bridge designs before using it. These social media companies are just run by money hungry a-holes.

If there are more people, there are more person-hours in the world that can be used to produce things.

The available API's on the web are very questionable. Feross has a web security lecture series on youtube where he showed off the following abomination. Enter at own risk.

No, in this case it is docker. Last I remembered, docker on macs run in a VM

For some the hairloss comes in the 20s

I get what you are saying. I was just thinking about the stochastic parrot analogy for consciousness, but I see your comment is more about there not being special sauce to conciousness. But hey, the fact that such behaviour can emerge from simple processes is still pretty damn cool.

> emergent property of complex-but-deterministic actions and reactions

I think you mean non-deterministic. The last century of physics was dominated by work showing how deterministic systems emerged from non-deterministic foundations. It seems that probability and statistics were the branches of maths behind everything. Who would have thought.

The fact that the market for cars is shifting in the direction of gargantuan pieces of metal is what finally convinced me there is nothing that can be done about global warming. Forget pedestrians, if everyone is starting to drive around in cars 1.5x - 2x the weight of the average car a decade ago, we are gonna waste a lot of energy.

The dopamine rewards you get from the two are similar.

it's not about gambling. The dopamine rewards you get from the two are similar.

If you prefer learning by doing, I recommend rustlings. Its a bunch of small exercises that roughly follow the content of the main rust book.

https://github.com/rust-lang/rustlings

The author addresses this in the text. He claims the wealthy have the time (And I will add access to resources like the internet and books) to spend on learning esoteric knowledge. From my N=1 experience, that seems to be true. I don't really get why that offends you. Is it really hard to believe that people in different social classes prioritize learning different things?

> If you do so much IPC that you have to design your language around it you're probably doing it wrong...

I'm gonna have to disagree with this. Often when languages add features to their core, it allows for a very different (and often better) approach to writing code. Think Lisp with first class functions, or Rust with the borrow checker. Why should concurrency be any different? This feels like a Blub moment and I would highly recommend you give erlang or elixir a try, just to see what it is about.

The US has enormous amounts of capital and the capital owning class aren't just sitting on their fortunes, but are actually investing in fresh blood. The US has a large, rich homogenous market making it comparatively easier to grow new businesses. The US has some of the worlds best educational institutions making it easy to find world class talent. Lastly, the entire population has democracy as a core value, so you'll never see a single person in power for longer than 8 years. There aren't many places in the world that have such a complete package.

Onur Mutlu puts his computer architecture lectures on youtube, their really good.

If I understand correctly, Elixir builds an Erlang syntax tree and then the erlang toolchain takes over. If it runs Erlang, it should be able to run elixir

Just wait for Neuralink brain ads, it'l come

Why wouldn't google cloud exist in 5-10 years? The scale of the project isn't the same as google reader or of their other cancelled projects.

Ah yes, I dont understand how to talk to people either!
