Unsafe rust exists for a reason. There are cases where perfectly safe code cannot be expressed according to Rust's ownership rules, and an escape hash is needed. Of course the "average" developer probably should not resort to unsafe as a rule of thumb.

Also regarding the standard library, as far as I understand it's not entirely true that it never resorts to unsafe rust. For example, I understand that the standard library makes use of specialization, which remains an unstable feature because of a soundness hole in the implementation.
Bitcoin is a potentially revolutionary technology in a very early stage. The important new part, the consensus algorithm, is ground breaking.

Now, the very first implementation (Bitcoin) kinda sucks, like most technologies in their first versions. But there are newer generations, each more interesting, and each unlocking more possibilities. We are for example getting:

* No-autority enforcement of contracts (Ethereum).

* A distributed computation (operating) system (EOS).

* Decentralised finance, for example lending platforms (AAVE).

* Cash-like payment system suitable for real-world payments (Monero).

We're only eleven years in so it's a bit too early to say if it's all rubbish or if it will change the world.
Follow the big money? The total "market value" of bitcoin is a rounding error in the global economy. Many individual companies have a larger market cap.
I suspect that at least some of disconnect over DST is between people living at 40-50 degrees latitude who have short winter days and those living further south.

I'm in your boat, when it was first explained to me in a hacker space at college when it was first growing and priced at a few cents per 100++ Bitcoin. All I could see was a waste of energy and resources (time, energy, hardware).

It will always be a drain on society, and it scares me that it hasn't failed because we see it draining our GPU industry to the point that market prices have gone insane and availability is practically non-existent / all left up to chance.

It does take a rocket science to see the trends, as long as it's tied to needing hardware to compute arbitrary calculations to work... It's going to waste computer resources and energy. Both which are finite resources... Yes finite, solar cells aren't free to make, they don't last forever after you make them. Same with any other green technology. Maybe if fusion was our only power source it would be less of a concern, but we still haven't cracked Q=1, so... Yes it is a waste of finite resources.

Ask HN: How do you deal with open translations and app store rejections
I have an open source app that is on github and connected to weblate which allows anyone to translate strings in the app as well as the store listing information. App updates are packaged with fastlane and sent to google play.

Doing this however I run into the risk of having my app pulled from the play store if someone writes something that is not permitted (the guidelines are getting ridiculous, my app was rejected yesterday because of a typo) in the store listing description. I can't audit this because I don't speak or read all languages.

Does anyone have any suggestions on how to deal with this?
In the US you can, as long as it isn't a "public performance" (there is a lot written on how to define this from a legal perspective) or any other commercial sense, I.E. Playing it in your business.

The only really shocking part of this is that Artifactory is vulnerable to this. I expect developers to be lazy about build security because I've seen it over and over again at multiple companies, but Artifactory's whole purpose is to provide secure build dependency management.

For that last one: it's much faster in many cases, because Chrome's engine is not parallelized.

Back when I was last measuring this, stylo's single-thread performance was comparable to Chrome's or a bit faster in some cases. Parallelized performance was much better.

That said, actual hardware in the wild has a surprisingly low level of hardware parallelism in practice. https://data.firefox.com/dashboard/hardware shows that for the Firefox user base as of end of Jan 2021 54% of users had 2 cores and 34% had 4 cores.

> Sending simple wires in the US takes hours

What? No. It happens instantly at a protocol level. Practically, about thirty minutes. Most people don’t send and receive wires and so don’t choose bank accounts that prioritise them.

Practically speaking, Venmo and Apple Pay and Zelle are frictionless and instantaneous and more widely adopted than Bitcoin. For heavy users of international transfers, there are usually better solutions.

There are absolutely edge cases, and so a legitimate use case for a cryptocurrency there, but that’s not enough use to sustain Bitcoin’s value. To say nothing of the transactional motivation having been long since abandoned when inconvenient for the current store of value one.
Can you point me to a documented instance where a warranty claim on a software product yielded a useful outcome for the claimant?

The only one I can remember was against Microsoft for forcing an upgrade to Windows 10, which wasn't (IIRC) a warranty claim but a bait-and-switch issue.
This is disgusting. Why is this stupid useless asset allowed to proliferate without regulation?

Why are we not concerned about harvesting this blockchain at the cost of the planet? This is silly. Bitcoin needs to be regulated like other industries. It’s polluting just the same. Regulation now please.

By that same logic, I should be able to pay for my groceries with Apple stocks by now.
The finite supply is a feature, not a bug. I agree there are many aspects of bitcoin that suck, but not this one. We are right now witnessing many governments printing more and more money, which makes it less and less valuable. Bitcoin avoids that.

This reminds me of a great interview with two ER doctors on Amanpour (PBS) two weeks ago. Pulse oximeters can be used to help detect which patients need hospitalization before they themselves notice, with astounding results.

It seems like such bad faith arguments to claim that bitcoin doesn't have a use. It has an obvious use. HNers might not agree that it solves the problem it claims to solve, but if that's what you think then argue that. Don't pretend like you "don't understand" what the purpose is.
We are there already.

You are looking at an example of mind-reading.

But it's an early version of mind-reading that requires expensive fMRI machines to get data from the brain and uses deep learning models that don't work that well... yet. There are other early examples of mind-reading, e.g., Neuralink implants.

From here on, it's all about improving the technology -- making it better, faster, cheaper, smaller, etc.
No, it's a question about why we're tracking what people are reading, and whether that's a good thing. It's why librarians were the only significant contemporary dissenters to the Patriot Act. They've created ethical standards around what they do, unlike tech professionals (outside of the FSF.).

As you've said, it's been years since that was proposed but it's still not helping because none of the off chain networks have gotten any traction.

There is no such thing as digital cash outside of cryptocurrencies.

The money in your bank account is a liability of the bank, it's not cash.
The problem that you and others like you have is you don't have any BTC and now are struggling to understand why anyone else would have any. I think it's mostly from the fact you didn't get any when you should have and now there is no reason as it's expensive and again you don't have any. Simple really.
Oh very, very nice!

Otten has more efficient solvers in "Part 3: Tableau and Connection Provers" but i find the sequent proofs much easier to understand (which makes sense, the "natural" in "Natural Deduction" means something like "intuitive" as used in IT.)

Unless sub-second accuracy is required, I'd be in favour of UT1. It doesn't use SI seconds (while TAI and UTC do), but it has the advantage that a day has exactly 86400 seconds, so you don't ever have to deal with "23:59:60" timestamps.

Summary:

UT1 - noon is when the sun is above you, day has 86400 seconds (not SI seconds)

TAI - noon drifts away from when the sun is above you, day has 86400 SI seconds

UTC - noon is when the sun is above you (+/- 1 second), day has 86400+/-1 SI seconds

Difference UT1-TAI: continuously diverging

Difference UT1-UTC: continuously diverging up to less than +/-1 second, then discretely jumps back when it gets too big (leap seconds)

Difference TAI-UTC: increasing in discrete increments of +/-1 full second (leap seconds)
Sure. My assumption is that absent formal time changes, schedules won't change and people will just live with what, for many, is sub-optimal schedules with respect to sunlight.
> Why would it be a problem to do a copy in this case?

How are copy semantics even defined unambiguously?

> Not if it is preceded by "def"

In that case it is analogous, def f(x) DEFINES what f(x) means. For class definitions it's different, and it is indeed debatable if `class A(SuperClass)` is good syntax. I would have preferred `class A from SuperClass`, but that ship has sailed.

> | means bitwise or.
Not if it had been overloaded, like many popular libraries do.

You missed the point willingly I think. See sibling comment. You cannot overload its meaning in a match, and the meaning is not related to what it otherwise means (bitwise or, set union, etc.).

> a means the value of a
Not if it is followed by "="

And again, this is by analogy. a = 1 means that you substitute a with 1 wherever a occurs. Not so with the pattern matching syntax. If we had a = 1 then a == 1. Where is this analogy for pattern matching? How do you even make the comparison? You do not.

All of your counterpoints have reasonable analogies within the syntax itself (eg: the inverse of a function call is a function definition).

Etherscan is the standard tool for looking up Ethereum wallet balances without having to run your own node: https://etherscan.io/ .

Top Accounts by ETH Balance: https://etherscan.io/accounts

#1 has 5%, but it's the wETH ("wrapped ETH") smart contract, that allows people to deposit ETH as the native token and receive wETH in return. wETH is more easily used for things like decentralized exchanges (https://weth.io/). So that's really a utility contract used by many applications and users.

#2 is the ETH2 Deposit contract, with 2.6% of supply. These are stakers receiving mining rewards for participating in ETH2 beacon chain validation.

#3 is Binance, with 2.5% of supply. They are the largest centralized exchange, so that 2.5% represents Binance's customer accounts.

#4, #5, #6, are also exchanges.

#7 is Compound Ether (@1.08% of supply). Compound is a decentralized finance savings & loan protocol, so again, that 1.08% represents tens of thousands of Compound users.

Bitcoin is over a decade old by now. It’s certainly not become a revolutionary technology and is not in its infancy.
These are all the same uninformed arguments that every newcomer thinks of. It's all incorrect, and if you'd want to learn correct info, then you'd be able to do so.

It's important that you do it yourself. Because when I tell you it, it isn't going to land.

Your ideologies don't matter. The world won't let you force them onto it. The reality of the situation, is that all the big money believes bitcoin has a large role to play in the future of the world economy.

And this is true.

Screenshot this. Message me in 2030. Let's reevaluate.
I think both the article and this comment miss the point.
If we generated power cleanly in the first place, there would be far less environmental damage everywhere.

The fact that Bitcoin now uses half the power of Youtube (from a terribly unreliable estimate) should not be such a distraction from the real problem IMHO.

This doesn't really answer why bitcoin though. Because we already have money that we've been using for a good long time.

The problem is that money now is issued by governments. Governments are on average only governing one country, although sometimes more as with the Euro. In other words, it is not universal, so if you want to exchange some money for goods and services then you need to find the right money for the country the service is in.

Globalisation means we often want goods and services from other countries. But then we always need to find the right money for that country or use some de facto universal money like USD. But then you're always exchanging money or letting the US government (who control USD) exert some control over you, even though you could be outside the US buying a good/service from a non-US entity.

Bitcoin gives you a universal money. Once you have it, you can exchange it for goods or services without caring about where the recipient is. And you don't have to worry that you've now created a universal money that is controlled by one non-universal entity like the USA.

At least that is the idea
Also, there would be absolutely no economic motivation to not exploit the data of the users of a for-pay service.
How much energy does watching porn consume? Playing video games? Watching a movie? Browsing Facebook? Using a ski chair? Visiting an amusement park? Going in vacation? Cooking your favorite type of food? Making ice cream? Driving to your friends? Listening to music? Concerts? Having a party? Banking? Casinos?

As a species we use energy to meet our goals. Those goals may be situated anywhere in our hierarchy of needs. Some are essential, some could be considered trivial. But they are all important for their consumers.

Bitcoin is now considered by some important for our future finance system. While not everybody agrees, this may be more important than countless other ways we use energy, for much more trivial reasons.

Being judgmental about how others use energy they pay for reeks of hypocrisy, virtue signaling and holier-than-thou attitude.
Legal requirements can be surprising.
It's hilarious to see the naysayers about Bitcoin say that BTC is not usable. Now it's worth almost 50 grand and all they can come up with is expensive transaction fees which in hindsight, are really not that expensive, and the energy consumption of maintaining the Bitcoin network.

It sure is a lot better than using human lives, usually & most likely forced labor, to mine real Gold. Right? After all, energy is free when you're using solar power to mine your Bitcoins or any other coins. Does the energy really goes to waste when it provides heating? Etc?

It just seems like people are running out of excuses at this point. I wonder what they'll be saying when BTC hits $100,000.

If everyone were to get excited about Monopoly money as a store of value, it would be wrong to tell you that you fail to see the huge potential. The crowd decided that bitcoin is worth something, and thus it is worth something. That doesn't make you wrong for not being part of the crowd.

Today Elon Musk chooses BTC and it goes up. Tomorrow the US government could crack down on BTC and it could go down. Maybe a technical weakness arises. Maybe the dollar breaks and it goes to a million. That doesn't mean it has potential, nor that it's useful. It just means there's uptake.

Maybe people close to Bitcoin know it won't be a usable currency, but unless you closely follow bitcoin, it sure seems like it is built to be a usable currency. Even the name implies this relationship, and the idea of a 'wallet' does too. Tesla just recently bought $1.5 billion worth for exchange, no?
Nope. That's what a medium of exchange is for.

Bitcoin isn't at that phase yet.

For any new money, it goes like this:

1. Store of value.
2. Medium of exchange.
3. Unit of account.

In that order. Cumulatively.
