It seems really weird to compare the energy consumption to that of a country.

"The total energy usage for the production of cars/yachts/fitness machines/musical instruments/toilets equals that of country X"

What does it even mean? How do you interpret it?

It seems more sensible to compare to total worldwide energy consumption of which Bitcoin takes roughly 0.05%
I find it a little weird that this story is being attributed to a "philosophy professor", when the lesson imparted is religious advice unrelated to what philosophers talk about.

As far as examining how the concept of "fullness" applies to jars, it's pretty straightforward to say that the jar is full every time, including before the giant rocks are added, but what it is full of changes. You can go in different directions from there -- say that "full" is underspecified and the students must infer a more specific meaning from context, or ask whether, if you cap a jar full of air with an airtight lid and chill it, it is still "full" -- but one place you can't go is "these rocks are actually your family".

For me the thing that soured me on him was his fixation on Tesla being the solution to all urban transportation problems and his loathing of public transportation.

He lived and worked in the Bay Area and L.A. - he's intimately aware of how pathologically bad car-oriented low-density city planning is, which is why the most economically successful place in the world is so hilariously bad to travel in.

But his hatred for transit demonstrates an almost absurdly opaque blind-spot for somebody who wants to get his businesses involved in urban transportation planning.

edit: corrected his experience with California commutes after reply informed me he was no longer involved in SF bay.

Is the obscure example that you are referring to the pocket calculator state machine at https://en.wikipedia.org/wiki/UML_state_machine#Hierarchical... ?

Between pocket calculators and GUI events (reactive programming), I think obscurity is probably a matter of personal experience. In any case, I think the connection to GUI events is worthwhile. Thanks!

I believe there are a few important caveats to the connection:

1. The "most popular" GUI frameworks have semantics that go (way) beyond "events are delivered to the lowest level in the component graph that can handle it":
https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Bu...

https://stackoverflow.com/questions/4616694/what-is-event-bu...

2. You can still have this hierarchical handling of events without modeling the event handling itself as a state machine. And if you do want to model it as a state machine, and if multiple levels of the hierarchy may handle the event, I suspect you must rely on some decomposition where each layer of hierarchy can only influence some components of the state, while leaving the others unchanged.

It seems like UML state machines addresses this!

From https://en.wikipedia.org/wiki/UML_state_machine#Orthogonal_r...

> In most real-life situations, orthogonal regions would be only approximately orthogonal (i.e. not truly independent). Therefore, UML statecharts provide a number of ways for orthogonal regions to communicate and synchronize their behaviors. Among these rich sets of (sometimes complex) mechanisms, perhaps the most important feature is that orthogonal regions can coordinate their behaviors by sending event instances to each other.

As you can read in other comments, this is a political game using a deadly epidemic as a wedge.

On the one hand there’s people complaining the rich countries don’t provide vaccines to the poor African countries. On the other hand South Africa doesn’t want to use the vaccine for political reasons.

Note also that even if the results of their studies are right, using the vaccine is still much better than not using it.

If they choose not to use it, which according to the article they do, I have about as much sympathy for them as I have for antivaxers. Suit yourself, as long as you don’t require me to quarantine because of your decision I don’t care.

Really? I don't think you're aware of what's actually out there.

Let's put it this way: Cloudflare has a straightforward business model. The fact that you can pay them is comforting. The big shady companies that you cannot even pay, yet still make money "somehow", are more scary.
I have a feeling the text to speech market is suppressed. For text-to-speech services such as Google or Amazon it costs more (end user perspective) to process audiobooks from eBooks. Compared to buy the audiobook through a subscription service.

Is this real? If so, can you direct me to any quick resources to play around with this? I have only surface-level theoretical knowledge about machine learning or AI. But this looks fascinating and makes me want to learn more.
I think it's important to believe you can improve, and that most people can improve with practice. This avoids the very real problem of people self-limiting in unnecessary ways.

I think that telling people people that they can achieve _arbitrary_ things through enough effort is just wrong: it sets up unrealistic expectations and makes them blame themselves when things don't work out, because they must not have tried enough. Telling someone who's 5 feet tall as an adult and not particularly athletic that if they just work hard enough they can become a successful Olympic swimmer is not OK.

It's a tough communication problem, because "maybe you can reach this goal if you work really hard and happen to be lucky too" is a much harder concept to communicate and internalize than "you can reach this goal if you just work hard". It's also a tough problem in trying to figure out what expectations ought to be "realistic" for a given child, because of all the biases we bring to such evaluations. So erring somewhat on the side of emphasizing growth mindset can make sense, and should absolutely be done when doing evaluation, but you have to be pretty careful how you communicate the resulting recommendations.

Past that, the unfortunate thing is that Dweck's disciples (and I use the word specifically for its religious connotations) go overboard on the "everything is possible with a growth mindset" thing, in exactly the way that I think is harmful. I see this in a lot of elementary school teachers; they love this book, but end up in the "growth mindset solves everything" trap, at least in their communication.

I should note that unlike many things in that field Dweck's work actually replicates in large pre-registered studies, albeit ones still done by Dweck herself. The effects are quite small on average, but maybe on the margin (i.e. for students who are more likely to doubt themselves for various reasons) might be significant.

That said, I would be happier if someone who is not Dweck were able to reproduce her results, and I have ~0 confidence that "growth mindset as practiced in elementary schools today" is at all useful...
I'm no expert on Google and I don't have a PhD but from my time working there (and my time working at other internet services companies), multiple of your assertions here are false or absurd.

Child porn detection and enforcement literally does not work that way. I'm not sure how you even think that would work. How do you think the algorithm gets trained? Humans feed data into it. All the major social media companies (Facebook, etc) have paid human moderators that have to screen flagged content in many cases to determine whether it is illegal and then escalate to the relevant staff or authorities, and in some cases this is a legal requirement.

The GDPR one is especially ridiculous. Why would you be required to delete a user's data the moment you suspend their account? That's utterly absurd, it completely eliminates the user's recourse in the event of an error. No reasonable human being would interpret the laws that way and the relevant regulators (yes, GDPR is enforced by humans) would never require you to do that.

Google already has measures to deal with malware on machines, typically temporary or permanent bans of the hardware and/or IP address. They don't have to permanently delete your gmail account to lock out Chrome on a single malwared PC. If you've ever done any automation or browsed on a shared network you've probably seen Google Search throw up the 'automated traffic' warning and block you for a bit.

Being able to review conduct of an account (i.e. browse logs) is not "blanket access to your account" and neither is being able to examine the details on why the account was banned and reverse them. The account owner could also authorize the employee to access their data - any time you talk to a Customer Service representative for a company, you're doing this.

The comment from Musk was inexcusable but it didn't come out of nowhere. Elon Musk offered help and Mr Unsworth decided not to use it. In a TV interview, he further labelled it a "PR stunt" and suggested that Musk could "stick his submarine where it hurts". That led Musk to respond with the "Pedo guy" comment. Yes, that comment was totally inexcusable and uncalled for but it didn't come out vaccum.

What it misses is graphical display on the REPL.

You don’t have to choose just one, single party to accept the blame. Bitcoin can be wrong even as other alternatives are also wrong.

Also the devil is in the details, and at least in some of these cases, Musk doesn't come off that bad if you actually care for the context.

That said, what surprised me here is how dangerous this is: Musk's Twitter is probably world's number 1 place for peddling Bitcoin scams. Anyone reasonable would of course immediately recognize the scams because there's no way Musk would have anything to do with cryptocurrency. But now, I predict a lot of folks will get scammed.
> I don't understand all the Crypto hate on this site. Since when have hackers become the luddites to new ways of finance?

For me, it's because nobody can explain what the value offering of Bitcoin is - mainly the question 'what can I actualy do with a bitcoin?'.

It's a bad currency because it is slow to exchange and costs lots of money to exchange - I can't use it to buy my coffee in the morning.

It's a bad non-speculative asset, because it can't produce anything to deliver returns.

But it's performed well as a highly-speculative asset - i.e. it's good because its value is rising. But other than the fact it's price is going up, what's good about it? Like where are the funamentals? If it's price was stable, why would people want to hold it? Is it's value just that it's value is rising?

And if the answer to the question 'what can i do with a bitcoin?' is 'Wait until it is valuable, and then you can turn it into a currency you can actually spend' then it's not actually fulfilling what it set out to achieve.
We've seen the playbook often enough. If you think they aren't going to close it down in 3 years, you're wasting money.

I don't think it's a good idea to install a dozen plus web apps directly on a server, such that a bug in one can compromise the entire server.
Sounds like it’s similar to how LuaJIT works [0], using a machine-code handler for each VM opcode. AFAICT LuaJIT also uses a templating system to build these, except it generates them at compile-time instead of at run-time. I assume that’s easier than explicitly writing out each handler in assembly language.

Hi claytongulick! Very glad to hear about your excitment.

We built a react library for our current customers, and we are planning wrappers for other UI frameworks, too. The core of the MagicBell client, though, is completely decoupled from React.

We also offer a UMD bundle you can embed without having to worry about React at all, and a ESM bundle. Our customers were able to embed it in products with very different stacks.

Sign up and try it! We'll be very happy to help you integrate MagicBell into your product.
I'm not creative enough, and I don't think it'd be well received here, but really wish I could just pull of some WSB type YOLO meme comment about buying tesla shares.

But, I see a bubble. Electric cars aren't magic, and I'm more expect Tesla to be outflanked by the East (Toyota) and then the Germans (VW Audi Group). Whilst they may be still doing hybrids, they've got years and years of Auto building experience. Also, Musk's persona is cult of personality that make's me wonder.
Considering you're talking worldwide energy consumption, 0.05% is a lot of energy. Just because the number is small doesn't mean it's not large by comparison.
bitcoin was just an idea a few years/a decade ago and is now here.

Its existing directly consumes as much energy as a whole fucking country.

I find that a very visible and easy comparision.

If i would invent something and it would consume that much energy just for transactions, i would consider this a gigantic issue.

> having a fossil fuel car for a year does not exceed the emissions of that flight.

That's true (-ish).

Here are the numbers:

Modern pure-ICE cars don't got below 100g/km of CO2. Round trip NYC-LHR yields 1 ton of CO2. So the above comment is true-ish for cars that do less than 10k km annually.
Tesla's mission is to accelerate the adoption of renewable energy sources. This doesn't directly counter that. In fact you could argue that pushing the world to rely on massively energy-inefficient proof-of-work rather than a centralized authority for trust in the financial system is going to make the need for renewables even greater.

If (and it's a big if) we can get to 10% renewable energy in the next decades, Bitcoin's energy consumption will be much less of an issue.
> Mark Perlin, is said to have argued against source code analysis by claiming that the program, consisting of 170,000 lines of MATLAB code, is so dense it would take eight and a half years to review at a rate of ten lines an hour.

>but I've never experienced the similar problem.

How do you know for sure that you didn't? One of the main takeaways from the original article is that these errors are invisible from server side (your own stack) because it's the traffic is being throttled before it gets to your own servers.
