I've be lurking heavily in the crypto-mining communities for a few weeks now. Most are saying they'll just "move to a new coin" which is basically all they CAN do, unless they cash out early and sell their hardware. Nvidia is releasing* "LHR" (low hash rate) cards to give gamers some relief (assuming they can't be jailbroken).

PoS burns capital in the sense that it could be invested in something else (I was looking at staking coins but it doesn't come near the yield I get from my 401k for example, which is effectively providing unsecured debt to finance innovation.)

IMO: it's much better than PoW as long as it doesn't end up too centralized. I'm not too sure how I feel about the minimum amount required to stake though, that seems a bit odd.
yes? That was literally my point, its less efficient, but can be okay in terms of final output.

Maybe this is a good time and place to ask - let's say I want to buy something using Ethereum. Is it correct that when I look at, say, https://ycharts.com/indicators/ethereum_average_transaction_... , you have to pay USD 20 just as payment fees? I wrote off Bitcoin as a payment mechanism a long time ago because of this (although it seems BTC tx costs are now lower than ETH?), is this the direction tx costs for all crypto coins go?

No, the do worse than electric cars in that respect. The hydrogen production facilities are very expensive, so they have to run 24/7 at the same load. This is exactly what mixed badly with the varying supply of renewables. With electric cars, you just plug them in at home/at work and they charge whenever there is an oversupply of electricity. Offering special remote controlled charging outlets is going to be a game changer for the grid.
> There’s been a lot of antitrust scrutiny on Google and it may have played a role in this change of heart.

I'm pretty sure that's the primary reason, which won't change anytime soon.

I'd also expect many publishers that adopted AMP to jump ship now, which means it will slowly die away.
It depends on the type of video processing and whether you can handle adding latency.

Right, the issue is though that in a collision you won't always just have a nice small controlled hole and burn.

I've worked around Hydrogen before, and storage was always a tricky issue. I remember the regulations stating something like needing to store the tank with either Argon or Nitrogen beside it. Not really something I'd want in the back, or any part for that matter, of my car.

Vertical integration in steel production could as easily involve intellectual property as it does here.

As a hypothetical example, imagine if Apple had sourced the M1 chip from a third party which it now proposed to buy. There would be intellectual property at stake there too. This case is no different.

And indeed, in the Apple hypothetical you could well expect consumers to be better off and for exactly the same reason: if Apple purchases an input (the M1 chip) from a monopoly supplier (the hypothetical non-Apple-producer), vertical integration removes one monopoly markup.

I do not know exactly what will happen in this case, but it seems like Amazon's proposing to buy a single studio is very unlikely to result in harm to consumers.

The copyright issues do not make the case relevantly different.
A human-managed forest and a naturally evolved forest are very different things. When we plant trees, it's basically another farm, rather than the rich ecosystem that was originally there and destroyed by us. They also have very different carbon dynamics. The only way to recapture that same level of carbon that the original forest had, is to "rewild" the land and allow a full, old-growth style forest to grow back, which takes a lot longer than just planting some fast-growing trees in straight lines.

I've been for a long time waiting for that crisis to pop up and I go back to my community to try something new, not as an employee but as an employer.

Many other software devs shared common concerns with me, like that it isn't worth to drop the ball now that salaries are sky high.

I think a recession would definitely annoy people, but like when it rains, it would clean up a lot of things. Too many zombie companies going on, big tech getting so much money as it seems the only thing that will stick around post-crisis.

If someone reading the post here is thinking that will be possible give power to "small devices" using WIFI, that is not and will not be impossible. We are talking about few micro amperes when a coin cell battery can deliver 220.000 micro amperes, as paragon. There are some niche applications in micro ampere range, but in that cases there are some reliable and more stable solution, like cesium batteries.
Dave of EEVBlog has a mission, debunk this wireless energy affirmation, explaining why it's simply impossible, for example:
https://www.youtube.com/watch?v=P8s3Xjeg0sk

Moreover the power is related to the distance to the wifi source and the presence of an active WIFI obviously doing this kind of solution at least impractical even for ultra low power consumption applications. An Apple tag uses a coin battery and I think will use that solution for a veeeeery long time.

I don't doubt these things are true to some degree in the abstract, but I don't understand how precisely these things apply to the specific extortive practices discussed above. Are you claiming that these practices have racist roots (I don't know and I'm not challenging; I just can't tell what if anything you're implying)? Are you claiming that these practices are maintained because of some ongoing racist attitudes which don't appear to be racist because "most Americans are so racist they don't perceive racism" or some such? What are the specific hypothetical mechanics at play here?
Eh, it's basically a new(-ish) way to make a small radio receiver but instead of converting the output power of the antenna into an input signal for an amplifier, they try to feed a small electric device with it. This is super possible and doesn't violate known physics in any way, but the amount of power you can transmit is minuscule. Still, it might be useful for some type of sensor where it is non desirable to have to replace the battery for some reason.
I feel like ETH is in very good footing to move to Proof of Space (decentralized network, good dev work, lots of distributed stake), especially in comparison to other projects that have gone with PoS. I'm sure it'll succeed in many ways, but I can't imagine moving away from Nakamoto consensus is going to be "the solution" generally for how to create a working, scalable, well distributed currency.
Yes, those locations will play a huge role in securing the global energy supply. However, the hydrogen will be desperately needed in the industry (e.g. steel production) and for supporting the electric grid in times of both low wind and solar. No good reason to waste it around the year driving cars.

However - and not because I'm the author of the language - once you get the general idea of Arturo (or any of the languages of the Rebol family: be it Rebol, Red, or Arturo), I assure you that you will find it very tempting not to ever go back to the C-inspired languages.

If I could sum up the whole (not-so-)syntax of Arturo, I would say that every "command" takes takes the necessary parameters on its right. And that's pretty much it.

print 10 ; that's a valid function call for example

or

print add 1 2 ; that's also a valid function call (or 2, to be precise)

and...

other than these super-basics, having a look into the library is pretty much all you'll need in order to get started.

I guess this isn't that difficult. :)

That's simply not true. Humans aren't machines. Productivity falls off a cliff after 50 hours, and after 55 you may as well not even be in the office. There are diminishing returns with "overwork"ing.

While I agree that there should be more outrage about other tragedies, "Better than Syria" is not the standard that I want to hold my country to, so I don't engage in such arguments. We (Israel) consider ourselves to be a western nation, with western ideals and standards. And so it is reasonable that we'd be called out if we fail to live up to the standards of the crowd we want to hang out with. I'd be disappointed if we started to be grouped along with Syria and Yemen.

I can sort of get over all that, I'm not going to sit here and take it personally because I know it's just broad strokes, but at the same time, if it is broad strokes, there is nothing to be gained here because nothing is factual and everything can be dismissed because it is too general.

Ps. Seriously, why is the grey subtext so hard to read? Stop with grey text. Please.
That chart is highly misleading, as it includes all smart contracts. In ETH a basic transfer (like BTC) is often cheap (although it needs to be even less!), however interacting with a smart contract can be more expensive. If you want to interact with a highly complex smart contract that pulls a lot of state it can be 100x the cost of a basic transfer... just depends on the code.
> Why do extra work that you don't need to do?

Because of the consequences.

Tesla had used customer-grade components for control & entertainment systems in their cars. Nobody else did that, what a smart thing to do! They recognized that there's a rule to break to cut costs!

...unfortunately, the customer-grade touchscreen panels in their cars were breaking so often for exactly the reasons why you don't use them in cars and go for more expensive and harder to obtain industrial-grade components instead that they were fined and forced to recall whole production runs.

Now, if you actually did figure out a thing that nobody did before in order to put less work or cut costs and achieve the same or better results - you'd be indeed smart. Neither Trump's campaign nor Tesla's use of customer-grade electronics were examples of that. They just did something that others did not because of other factors than their intelligence.

Some rules are there for a reason and breaking them does not make you smart.

By that you must mean Tesla bothers to do the full suite of EPA tests instead of accepting a somewhat penalizing multiplier, like how other manufacturers do?

There's no rigging whatsoever and the same option is available for other manufacturers as well. If they bother to do the longer and more demanding test cycle, that is.

I know this is a pressing matter, and that has relevance for itself, but after the whole Elon Musk thing it just turns this into a reply to his tweet, where so many cryptos folks were spamming "we use less energy then bitcoin! choose us! we're open to talk!"

Which in the lights of the recent events sounds like: "pump us this time around!"

Makes you question: when would be a good time to address this, if they can't time travel to the day before Elon posted the tweet?

And I don't know the answer to that. Was this too soon? Well if they want to take the ride of Elon controversy, I don't think so. Is that a good thing? Who knows.
> the initial distribution of the coin has to be wide enough

I don't understand how proof of stake works to the depth I understand proof of work. But this reassures me that it's feasable that they'll accomplish the same distributed consensus.

So then, could I say that Ethereum proof of stake will allow the owners of the coins (ether) to be independent from the owners of the mining operations?

or uhmm...

is the independence between the computaional costs of the "mining" and actual minted ether?

Is it not possible there's good reasons they didn't move to proof of stake sooner? "Came to their senses" seems to imply they had no good reasons.
I was fairly into the space in 2014-2016 but stopped paying attention the last few years. It seems like lots of theorized applications actually exist and have a proof-of-concept now.

If I’m building a marketplace business in 2021, where I want to be “crypto-first” instead of relying on PayPal and Stripe Connect, where do I start?

The marketplace sells access to resources with an off-chain ACL system. It facilitates trades between resource sellers and buyers.

I assume I want a smart contract between buyer/seller to record resource grants on chain, which the access layer checks as a source of truth.

But if I were to do this on Ethereum, the gas fees would be really expensive. I’ve heard about Polygon and “optimistic roll-up.” Is this a viable solution?
So maybe it's not "Use less chalk" but "Use chalk less"?
"I'm confused by the extent to which you believe the things that Erlang and OTP and the BEAM do have been entirely replicated by other ecosystems."

One of the reasons I make a bit of an accusation that the people bedazzled by Erlang/Elixir may be not very experienced is that a common take away from the community I have repeatedly noticed is the belief that if another language doesn't have exactly what Erlang has, warts and all, it doesn't have what Erlang has. Thus, I see in many other languages various attempts to port the exact thing Erlang has out into that other language, when in fact the other language already has solutions to that problem, even if they aren't exactly how Erlang solves it. [1]

While I personally exceedingly strongly agree that the Erlang-like threaded approach is vastly superior to manually explaining the asynchronous-ness of your code to the compiler, it still remains the case that "async/await" largely solves the problem of handling millions of threads at a time in those languages that support it, and even if that particular element of it is inferior to Erlang, it will be compensated for by the wide variety of other things that are superior. Just because it isn't exactly like Erlang doesn't mean it's not decent solution. Moreover, my exceedingly strong agreement is also, like, my opinion, man, and there are plenty of people who disagree with me and consider async/await superior, and they would account this as simply being better than Erlang/Elixir.

In the 1990s and the 200Xs, Erlang had solutions to problems that no other language had solutions for, or where Erlang's solutions where clearly head and shoulders above. In 2020s, Erlang no longer has anything that it uniquely has the solution for, even if the exact Erlang solutions don't exist elsewhere.
