die hard
Wow I was not expecting that to be so good
The fools talk much more than the wise. I wonder about just blocking most of the people I don't find interesting. Then I could only see writings from sensible and interesting people.
Maybe there is a technical solution, which doesn't require so much effort by the user.
Yes block chains predate bitcoin and are very useful. Git uses them. A currency is a perfect use case for a block chain. You need to robustly store balances and transactions so they can't be tampered with.
I would say it's insane to have a currency which is not block chain based. Too easy to fiddle your finances.
Proof of work isn't a necessary part of it. You need to answer the question "how does money get created". Proof of work is a very robust way to create and allocate new money. Fiat currencies just answer " i nominate one entity who is allowed to create as much money as he likes”. Other answers are possible.
It's also possible to use a proof of work algorithm which doesn't consume much energy. The usual proposal is for a "proof of doing work and allocating RAM and storing something on disk". Bitcoin just chose the most robust and simplest algorithm, which does consume a lot of energy.
In a future currency, the proof of work algorithm could allocate money to people who sequester carbon or plant trees. The thing about inventing a new type of money is that you can do anything. Bitcoin is a great leap of progress for humanity, but has a couple of flaws. Those flawed features can be reinvented, while still keeping all the benefits.
For a start, bitcoin is revolutionary. It solves all the problems with the banking system.
For example, people's card details get stolen all the time. Bitcoin had solved this by using a new public key for each transaction.
When something is purchased using a credit/debit card, you are effectively using the same public key for every transaction. So what is happening is replay attacks. This type of scam is inevitable because the banking system is insecure by nature. It's built on a foundation of insecurity.
Bitcoin fixes all that. Bitcoin or similar is necessary for money-based economies to continue to work in the future.
Bitcoin and crypto are more than this. This is just one of the important innovations bitcoin makes.
is there any evidence that this actually happens, or would happen?
all i ever see is humans being blocked or frustrated by the bot. i have never seen any kind of malicious spamming that could have been prevented by such a bot. spammers are normally thwarted by human mods.
the bot seems obsolete.
it's in the article. diverting around weather patterns where an AI said contrails were likely to form.
it's hard to judge how real the result is. it's early days.
The lemmy devs and users are rigidly against hate speech / free speech. they are afraid it will push away many users who are more sensitive, and ruin the quality of discussion. they don't tolerate free speech instances.
but who knows, they might be right.
yes. this is what most people don't understand.
even if you build a giant metro network, you can have worse congestion and pollution than ever. many cities have exactly this problem.
the only solution is increasing the housing (and reducing vacancy) in business districts, and providing more work places in residential districts. commuting distances have to drop to within cycling/walking distance.
But three is money to be made by making the problems bigger.
people have lots of different reasons. some don't like the idea of killing a big animal with feelings and expressiveness. some because of how farms abuse or torture animals in some countries. some think Anibal farming is worse for the environment. some have religious prohibitions. some think it's bad for your health. some people don't like the taste or can't afford it but don't want people to think they are weird so they tell people they have a principled argument for it.
For private business the tickets are to fund the business. But for public transport they are never expected to cover the costs of the business.
It is run as a public service, not to make money. The function of tickets is to prevent overcrowding.
That's why in well designed systems, the price is different at rush hour, and for high traffic routes and times.
I don't know anything about montpellier specifically though.
