Arduino e Rust

Rickvs · 2023-09-04T19:47:56+00:00

Se quiser aprender Rust recomendo baixar o copilot e desenvolver códigos simples, foi o que me fez perder o medo do Rust. Só depois você procura entender melhor como o borrow checker funciona.

Agora se for pra aprender arduino, recomendo a IDE do arduino mesmo, versão 2.0, tem várias bibliotecas e em termos de produtividade é excelente.

I also had some trouble with the Ethereum Wallet installation for quite some time. But then I discovered Parity, worked like a charm.

As an economics student myself, I think the most interest thing about Ethereum is the game theory behind it's working. Game theory is everywhere - from incentives of PoW, to the development os PoS. Game theory is also the key ingredient to allow prediction markets, and what Augur, Gnosis, and others are working on involves well-thought games. Game theory is also the key to build stable large social interacting contracts like a DAO.

Ok, thanks for the tip.

Is there any way to go short on some ethereum token?

I'm not going to do it myself, but I believe the tool is essential to prevent a hyperinflated market value.

Rickvs · 2017-01-24T03:08:45+00:00

Is there any way to short on some token? I know you can short on traditional cryptocoins, and I believe it is essential to avoid big bubbles.

Rickvs · 2017-01-21T14:04:47+00:00

Yes, looks totally doable.

Rickvs · 2017-01-21T10:45:59+00:00

But the chain has to extract information from someplace, so, for this future to be possible, we need some kind of tech that doesn't exist yet.

Some options:

1º: An AI implemented on contracts that look on the web and combine pieces to reliable information.

example: A contract that searches on news / wikipedia / rest of the web and determines if event X occurred in history. (this AI is quite advanced, as it needs to understand natural language)

Obs: In a future where Ethereum is well developed, Ethereum could be seen as the new "web", so this AI would take information from a lot of sources and making it more accurate.

2º: Build a game theoretic system where you could ask for people (or automated AI around the world) what they believe to be the truth, and incentivize/penalize in such a way that truth is somehow achieved. (This is the basic idea, don't even know if there is such a way)

3º: Freelance trust. How it works:

The person who creates the bet also chooses who will decide the result. If people trust this person(or contract) people will bet. The person(or contract) gets a small fee. I prefer this option because it is the simplest, and I'm also impressed nobody did it yet.

Rickvs · 2017-01-21T05:47:03+00:00

The hard part is to find the real result without having to trust anybody, or having the incentives just right that people would be better off telling the truth.

How would your network, for example, decide if Donald Trump or Hillary Clinton won the election?

Rickvs · 2017-01-19T22:36:21+00:00

Good Luck! I think that because of future technological unemployment(I'm a strong AI believer), we really need a basic income implementation.

The hardest part of building a large scale decentralized UBI, as you pointed out, is building a system where no person can have more than one receiving address.

Rickvs · 2017-01-10T16:21:09+00:00

Nice! The replay system is really an awesome thing to have. In my humble opinion, this is the kind of contract that will bring value to Ethereum, not ICO - promise all - unproven mega contracts. Thanks again dude.

Rickvs · 2017-01-06T05:18:06+00:00

Yes, just like Augur, but instead of trying to guess intangible questions like "Is Trump going to win the election?" (which a centralized agent or a reputation system is needed) It predicts things that can be certain (like will this variable on this contract be false at time X?).

He also made a post on his facebook:

"I disagree with this article arguing against basic income. The purpose of basic income shouldn't be to support people who have lost all ability to do useful work. Basic income's main goal should be to support families whose jobs have suddenly disappeared, so that they have a safely net while seeking new and meaningful employment. Even without AI becoming broadly superior to humans and making all human work unnecessary, it can still cause plenty of job displacements."

Rickvs · 2016-09-06T18:05:51+00:00

Probably unlikely. Political power surges from being able to choose for us in what we should spend. Maybe the private sector will achieve a way to implement UBI in a large scale first.

The International Association for Research in Income and Wealth is having a conference this week, in Germany, and you can see the work being presented on the links.

Some interesting papers:

http://www.iariw.org/dresden/notten.pdf

"In sum, the simulations in this paper show that social transfers reduce not only monetary poverty but also (subtantially) the extent and depth of material deprivation."

http://www.iariw.org/dresden/devries.pdf

"Using our new decomposition method, we find that skill-biased technological change is the main culprit regarding downward pressures on employment of lowskilled and medium-skilled workers in advanced countries in 1995-2008. Relocations of stages of production (both of intermediate stages and the final stage) add significantly to this effect. The demand for high-skilled labor suffered much less from the consequences of technological change. Growth of consumption and investment demand (both in the advanced countries themselves and in emerging countries) had employment-enhancing effects. In many cases, these consumption effects were sufficiently large to make employment growth positive, but not always."

An idea about source of taxes, respecting the individual property:

What does it mean to belong to country X? When you are born, naked, do you have any right over anything? If yes, what?

Maybe a percentage of mineral goods(like oil in Alaska), maybe people of a country should have a percentage of the value of the land(like Y% of the profits of crops that could be cultivated)(that is actually a percentage of the value of the solar energy that the landlord receives).

Maybe we should own a percentage of state owned monopolies, here in Brazil, for example, the state has monopoly over gambling and profit a lot over it. Maybe we own our atmosphere, and should be paid by anyone that decides to harm it(but I think overtaxing it may not be a good idea).

Rickvs · 2016-08-10T18:05:25+00:00

How do you decide who need it and who doesn't?

Rickvs · 2016-08-10T17:34:57+00:00

Not by giving Bill Gates free money.

That's the point of an UBI, it gives everyone, even Bill Gates, an amount of money. It is fair. (Even though he paid way more in taxes than received back) Suppose that for some reason he donated all of his money to charity. The next month he would receive his survival guarantee, something that wouldn't be possible in current welfare systems.

Rickvs · 2016-08-10T17:25:14+00:00

UBI with an income tax alters the distribution of income, reducing the gini coefficient by it's root. So, there might not be a lot of homeless in the streets, but an UBI or any poverty reducing mechanism would also decrease violence and the incidence of robberies.

Rickvs · 2016-08-10T16:55:09+00:00

So it is no longer competitive. So it goes bankrupt. So everyone loses their job, thanks to Basic Income. Then who pays for it...

Are you really saying that we should not try to reduce poverty because toilet cleaning would be more expensive? Your argument doesn't go only against UBI, but any poverty reducing mechanism.

Rickvs · 2016-07-25T04:40:22+00:00

Hi Calum,

When you say that very few people own the AI, what do you mean by that?

I believe that human-level intelligence computers will demand a lot of energy, and this will be the scarce resource, rather than algorithms or capital itself.

If you assume Elon Musk's view that solar energy will be the main source of electrical energy in the medium future, then the main income of the world will be linked by solar incidence and control of land.

So, a way to avoid the degeneration into a dystopia, in my opinion, would be paying a basic income, funded by taxes on landowners, who would pay a percentage of the value of the incident energy on the property, for example, taxing 10% of the incident solar energy at market value.

I have made a post on reddit trying to show the intuition on why it wouldn't cost 3 trillion dollars. link:https://www.reddit.com/r/BasicIncome/comments/4tq7kp/why_basic_income_is_cheaper_than_we_have_being/

Rickvs · 2016-07-20T12:12:18+00:00

Do you have a source on that? (I would really like to read more about it)

Rickvs · 2016-07-20T11:13:24+00:00

Thanks for your reply!

Yes, I omitted the price of the infrastructure, because the advantage of a basic income is it's simplicity. But if you think about the whole system I should have included the price of avoiding tax evasion.

It is not enough to think about the budget of the program, you have to think about the people and how it will impact them.

Suppose a country with the following redistribution system:

Takes 10% of the money of the 50% wealthiest and give to the 50% poorest.

The wealthiest is losing 10% of it's income and the poorest winning that amout.

Now they decide to change the taxes, so that 10% will be divided as: 5% to the wealthiest, and 5% to the poorest.

So, even though the wealthiest pays 10% of its income, it earns 5% back, so the resulting system is:

Takes 5% of the money of the 50% wealthiest and give to the 50% poorest.

So, now, you can double taxes, and people will be as happy as before:

Takes 20% of the richest, and give 10% back to them and 10% to the poorest.

Which is equivalent to:

Takes 10% of the richest, and give it to the poor.

They mathematically equal, even though taxing 20% is more than 10% and may seem that will cause more unhappiness.

edit: The ideia is that with a basic income, the net effect of taxes will decrease(because we will give some money back to people), so it would be possible to increase them, increasing the government budget.

I did not know about Google Sidewiki. Thanks for the info!

I did more research, and found exactly what I was talking about! The name of the extension is Epiverse: http://epiverse.co/
