No one is asked to refrain from commenting, but everyone is asked to comment within HN's guidelines, which call for respectful, curious conversation, avoiding flamebait, political/ideological/national battle, name-calling, fulmination, snark, and other internet failure modes: https://news.ycombinator.com/newsguidelines.html. It's that simple—in theory. In practice it is not so easy.

People sometimes imagine that the rules say that political threads are off topic, but that's not so at all. Stories with political overlap are inevitable here, and not a bad thing (as long as they don't get too dominant in the overall mix). They only become a bad thing when people descend into name-calling, flamewar, and the rest of the above list.

Not a question unique to NFTs

https://en.wikipedia.org/wiki/The_Physical_Impossibility_of_...
even with art, an NFT doesn't confer copyright rights, so you don't even own the art.

> But as it turns out, you can make digital things scarce, through cryptography.

The art isn't stored on-chain, so it's not scarce either.

All the NFT is is a pointer that has some text about who created it and what it points to. Not sure why why that pointer itself is valuable except as a status of "i am the only one that owns this unique pointer".

Of course there's nothing stopping anyone from creating another pointer that points to the same thing as the one you just bought and selling that.

So unless you find some value in pointers, intrinsically in themselves, NFT's are useless.

How do crypto currencies diminish the ability of governments to issue bonds?
Gambling, e.g. casino or sports betting is different because for some it's a fun pastime and participants are (more or less) aware of what it's about.

"Crypto" - not the underlying tech which is potentially interesting and may have merit in some incarnation - but buying or trading "assets" grounded in the tech, is essentially a quasi-legal pump and dump scheme right now. There is a rich history of securities law that is designed to thwart predatory investment schemes, and all of that has been circumvented by allowing people to trade in these assets.

I generally agree that adults should be able to do what they want, but I don't think we have found a way to balance that with what right now is effectively one big fraud.

So if llvm was released under different license, this is fully on llvm author. They had reasons to release it under the license that fitted them best.

Show HN: A streamer library to help you build publisher-subscriber systems
Hello everyone,

I've built a general-purpose event streaming library that can be used to implement internet facing message brokers and publisher-subscriber systems.

It is called Netstreamer and is written in Java.

The code is released under Apache License 2.0.

Feel free to use it and contribute if you're interested.
Node.js – v15.13.0
No idea how that answers my question.
I think there's a bit more nuance to this than a binary "does" or "does not" have authority. I'm not claiming it's unconstitutional to ban crypto, or that they literally don't have the authority.

I'm claiming it's a bad, authoritarian move that isn't in the interest of their constituents, and is not in the spirit of US laws.
> It does not confer copyright.

Why don't they? If NFTs tokenized ownership of the copyright of the referenced media (maybe through some kind of transferable copyright assignment contract linked to the given token), then maybe they wouldn't be total bullshit.

Meaning that, if they did confer copyright, maybe they actually would be useful and a good idea.
If my computer was spewing out clouds of black smoke, I might start to care
There's a lot of nuance here, though. Say that the song kicks around and kicks around a bunch of artists refuse it and then eventually an artist makes some changes to it and personalizes it, records it and makes it big. All of a sudden, because of the promotion behind that artist or whatever, the song has a lot of value. And the artists wanted points before they invested the time or whatever in to it.

I'm not saying that its right, only we always want to simplify things that aren't really simple.
Can you elaborate on that opinion?

Brazil isn't doing nearly as much to slow spread. Less masks, less lock downs. None of them work to stop covid, but all make a small difference and small differences stack up to big differences.

Note that I didn't mention vaccines. While Brazil is behind there, it is debatable if there is any possible vaccine plan that would make much a difference there yet. Soon though vaccines will become an issue in deaths around the world. (it already is a factor in a few countries, but most countries just don't have enough vaccines total for it to make a difference)

> This article seems to intentionally ignore the core reason for cryptocurrencies; escaping inflation

I'm extremely confused by this argument that I see again and again. If you want to avoid your assets losing value to inflation that you can buy assets that are resistant to inflation, such as stocks, real estate, land, gold, inflation-adjusted bonds ...

I just don't see that cryptocurrencies are particularly useful for that. What's the deal here?
I'll give this one an upvote just for the discussion of an article written by someone that has a serious bug up their butt about testing (if you will allow the pun). As another commenter points out, it's Poe's law in action, though I'm leaning toward "they're serious, aren't they?"

My only rebuttal is that if things can be tested manually, as is the preference of the author, then you're either:

1. Building a toy app, or at least one that doesn't do more than a handful of things

2. Are not testing as thoroughly as one might think

3. Are going to soon be overwhelmed by the testing workload

4. Are going to start missing bugs, especially regressions

5. More than likely all of the above, with the possible exception of #1
It's difficult to balance access with conservation. I don't feel that limiting access is the right approach on its own. There's clearly a demand for visiting scenic parks, and why would I have more of a right to visit than anyone else? And seeing natural beauty is important for valuing natural beauty. As others have pointed out, it's mostly the main sites in a handful of parks that are overrun. I think it's unfortunate to effectively sacrifice some of the most beautiful parts of the country, but it might still be a fair tradeoff.

There are room for improvements, though. For one, I think parks could have strict enforcement and fines for littering. Second, driving into a park usually means wasting a lot of time getting through the entrance station and finding somewhere to park. Post-COVID, I wish parks would provide better public transit into and within a park so driving isn't as necessary. Similarly, I wish they would set a cap on daily car entrances and let you purchase admission online beforehand.
Bootcamps seem most useful for taking people who are already qualified, prepping them for interviews, and introducing them to companies. Someone with a PhD in Computer Science might actually benefit.
The following rant is probably obvious to a lot of people but I really have to get it off my chest.

I really don't get NFTs. I feel like every article I read about them (even the critical ones) is describing them in a way which then turns out to be far more mundane.

People (such as the author here) talk about how they are the digital equivalent of trading cards. Pokemon, M:TG etc work because the cards themselves are hard to accurately duplicate. But the images and other digital items supposedly traded via NFTs can all be duplicated easily, like any other file on a computer. The only thing you get here is a record in a database with your (virtual) name on it next to a hash of the file. That's it. It's not even like your 'ownership' according to this database would have any legal implications.

A real world example might be a card system where anyone could easily scan and print out the same card as the one you own, but that in some database somewhere, there's a record of your ownership of the card. It doesn't matter. Everyone has a copy of your card anyway. The reality is that you aren't the owner of it, whatever your protestations.
>The most expedient actions would be fourfold:

>Halt foreign entities trading in dollar cash-equivalent crypto assets.

If a regular consumer searches for a VPN product they get a million results, all with different deals and they'd have to figure out how to find the best one and will still be around in a year.

What's the difference between struct and class in C++? IIRC the standard says they're the same except that members are public by default on struct and private by default on class. You could as well argue that C++ doesn't have structs.

The different allocation between structs and class objects in C# is a total head scratcher. Didn't it ever occur to the language designers that someone might want to choose how to allocate memory?
There are generics and dependent types. But these are still gaining features and not nearly as powerful as templates and SFINAE. (but way easier to understand)

Macros are an option but don't have access to the same type information so often they solve different problems.
exceptionally clear explanation, thank you.
The Rust book as currently written assumes that the user has some programming experience. That's mainly b/c there hasn't been much of any experimentation in teaching Rust as a first time programming language. Although obviously it's been done for C++ and even C, so it ought to be quite doable, if perhaps with a bit of a "learn programming the hard way" style.
It seems likely that there probably were some small number of unreplaceable works, but there may have also been a gigantic number of tax records and such. This is just based on the history of what writing was largely used for in the ancient world.

> I do wonder if Rust is easier or harder than other comparable languages like C / C++ when the person has no prior knowledge of programming.

I can answer this because I previously taught the course in C and C++. The students supposedly have some knowledge of Java but they seem to always have forgotten all of it when they reach me.

Students learning C use all of the footguns you can imagine. The biggest problem for them is writing code that segfaults, and their code always segfaults. It's not so much a problem that it does, but that there is 0 useful feedback as to why the segfault occurred and where they could potentially look to fix the problem. The bigger issue for them is memory management. They frequently walk into the use after free, double free, and memory leak walls. They also have significant trouble with N-dimensional pointer arrays. They have trouble allocating the appropriate memory for these arrays and can't seem to visualize the layout of memory.

C++ is a little better because they have experience with Java, but they are frequently mystified by constructors/destructors and how to manage memory manually (they only have experience with a GC), and template programming is always an issue. But they still run into the same issue with segfaults.

Rust makes all of this go away. They don't have to manage their memory manually, and they don't encounter a single segfault. Ever. We are able to just sweep all of those problems under the rug, and move on to actual content. With C/C++ we focused a lot on the language with the hope we could use it as a tool eventually, with Rust we use the language as a tool and focus on the wider world of applications for which that tool is useful.
The worry is not about ML. It's about bot farms in India/China with real people behind the wheel. That's why CAPTCHA needs to be able to evolve without maintenance from the website operator.
Agreed, I would have no objection to having more typographic tools on the web around stuff like line height.

I don't want to get rid of `em` units, because they represent the font designer's vision of how the characters are best sized and positioned. I regularly do want to defer to that in my interfaces.

But yeah, lining up fonts is a pain in the neck. The author is right, it would be nice to allow line-height to be defined more consistently. It would be nice to allow me to somewhat size two fonts to be the same height or width as each other without eyeballing things.

So no, not pixels, but sure, have more ways of talking about font size based on concepts like baseline and cap height.
It’s a good question. I’d say that the government already gives itself the right to mandate how you burn your petrol for example, by setting emissions regulations.

And more pragmatically, banning crypto would be less politically suicidal than implementing a carbon tax
I get what you're saying, but Samsung is also huge and Bluetooth is used in lots of electronics that Samsung sells -- including laptops, tablets, smart watches, TVs... or conceivably could sell, like future IoT products.

If someone senior at Samsung said to their vendor "good Bluetooth or you lose the Samsung account", that would provoke some, um, intense conversations at the vendor between sales and engineering.

Incidentally Apple sometimes has more than one vendor too, so it's not just two parties. I know cases where they've had two suppliers. Displays and modems come to mind, although I've not Googled to verify.
Gold definitely has value:

- it's rare but not too rare

- malleable

- doesn't rust or tarnish

- non toxic

- doesn't need the tech that platinum, the only other possible choice that satisfies the rest of the list, would need for it to become money instead

Useful and scarce == valuable.

>This article should be re-titled "The Political Case for a Blanket Proof of Work Ban".

I don't see the difference between that and "The Political Case for a Blanket Cryptocurrency Ban". The outcome is the same. Etherium has not proven proof of stake can work at scale. If it does that will be great. But it's no certain thing and it'll probably mean more Eth forks like Eth classic. Most other cryptocurrencies are tied to bitcoin's ecosystem to have value at all.
>Bitcoin is the textbook speculative mania for our time.

This is either false or unknowable, there are plenty of reasons why bitcoin speculation is happening, and it's because it has been a very long time since there has been a new desirable commodity.

>The largest elephant in the room is the environmental damage done by bitcoin mining.

This is very true, i don't think it's the largest elephant though.

>Cryptocurrencies disproportionately victimize vulnerable people and those in marginalized communities without access to traditional investments or financial advisory.

This is nonsense. Desperately marginalized communities have no access to safe economic vehicles, which bitcoin does, theoretically, provide.

>Cryptocurrency is, by design, the single greatest enabling factor in the rise of exponential explosion in ransomware extortion attacks. A network which is designed to evade sanctions...

This i believe is the best argument for banning it. There is no better tool for extortion in the world than an anonymous, unrestricted asset. We should expect to see a dramatic rise in kidnappings worldwide in the future as bitcoin becomes more accepted.

The author leaves out what I believe is the main reason I've stayed away from bitcoin, and it's another reason to ban it.

It's easy to steal.

It only takes one 0-day wipe you out, irreversibly, and completely. My bank could get hacked, but we, as a society, can just decide that I still have the assets I had before, the paper stocks and coupons are in a drawer somewhere. The loan contracts are in a filing cabinet (or they should be). I get my bank statements every month. There's some cash and some gold in a vault. A breach is, at least theoretically, reversible. That's not true with bitcoin.
So yesterday in HN there was a link to a medium post on the same thing, but limited to Proof of Work instead of the whole cryptocoins. Got flagged pretty quickly, but there was a link to a petition inside with links to various problems of proof of work: https://www.change.org/StopBurncoins

IMHO the problem is not cryptocoins themselves as is suggested here, but just proof of work.

A total ban would barely work anyway, as the system is completely decentralized, and to fully ban it we would need basically all countries to agree on the ban.
