I find a balance between this using git on JSON files. And I build the JSON files into a database (1 file per record, 1 directory per table, subdirectories for indexes). The whole thing is pretty beautiful, and it's functioning well for a user-account, access management database I'm running in production. I like that I can go back and do:

`git diff -p` to see the users who have signed up recently, for example.

You can get the code, over at: https://github.com/i5ik/sirdb

The advantages of this approach are using existing unix tooling for text files, solid versioning, easy inspect-ability, and leveraging the filesystem B-Tree indexing as a fast index structure (rather than having to write my b-trees). Another advantage is hardware-linked scaling. For example, if I use regular hard disks, it's slower. But if I use SSDs it's faster. And i should also be possible to mount the DB as a RAM disk and make it super fast.

The disadvantages are that the database side still only supports a couple of operations (like exact, multikey searches, lookup by ID, and so on) rather than a rich query language. I'm OK with that for now, and I'm also thinking of using skiplists in future to get nice ordering property for the keys in an index so I can easily iterate and page over those.

I founded a blockchain project dedicated entirely to NFTs. This is clearly a bubble. There may be some long term value in these NFTs long in the future simply because they will be some of the first NFTs ever made and NFTs will eventually possibly be extremely commonplace (offchain in-game items in MMOs, etc.), but IMO it would be prudent to just stay far, far, far away.

many properties of photons are quantum in nature, relying on an underlying continuous wave function, that when "measured", will output some discrete value. The wave function determines the likelihood of each possible measurement value, with the relationship amplitude^2 = probability.

I was similarly confused about which property of the photons they were measuring, it seemed they might be measuring the number of photons over specific periods of time. Because the position of each individual photon is uncertain until it is destructively measured, randomness will be generated by the "collapse" of the wave function, where one of the possible outputs is generated. Before measuring, photons can be in a "superposition" of bouncing inside the bow tie shaped chamber, or escaping out of the laser to be measured. After measuring, a photon can either be inside the laser, or outside the laser, but not the "both" of a previous superposition. Arguably, superposition isn't really a "both", but there aren't great words in English for this unfortunately. The fundamental uncertainty of measuring a superposed quantum state has been convincingly demonstrated in experimentation, but nobody really knows _why_ it happens this way. The "measurement problem" has inspired many interpretations of quantum mechanics, but many of them are unfalsifiable.

> There is no such thing as "excess power" for crytomining.

I was thinking the idea seemed to have some validity.. For ex: storage of solar/wind-powered is critical and the current inefficiencies and batteries rely on lithium and alternatives are still in research.(http://worrydream.com/ClimateChange/#moving-storage) ..

so in theory there's a system that can be built around the excess energy(of renewable systems) + crypto mining as a incentive for taking up renewable energy setups.(Of course this cannot convert the mined stuff back to energy so it's a one-way stuff at best and has it's own cons and pros).

Sure, I suppose you could link ownership of intellectual property or actual goods to NFTs, but what's the benefit? Who enforces it? And what happens when crypto is broken and people can't prove they owned the private keys?

What I’ve generally heard about nuclear and the grid in general is that it’s cost-ineffective to build out generation capacity to meet peak demand and that nuclear power is relatively bad at meeting fluctuations in demand. Sure, you could use batteries or whatever to store/use the power that the grid currently doesn’t need. You could also build aluminum processing plants or arc furnaces or whatever. Cryptocurrencies would be interesting because the mined cryptocurrency could used to reduce rates to consumers.
LOL. Tell that to Alberta, with its $47 billion worth of orphan wells, some 50000 of them unreclaimed. “A report from the Alberta Energy Regulator shows that, since 1963, there have been more than 440,000 wells drilled in the province, and only 67,000 have been sealed up through the oil and gas industry’s abandonment process.”

> The scaling past a Costco metric applies to Bitcoin

That isn't what you said. I will remind you again since in every reply you seem to re-write things.

> "it’s not possible to build a crypto payment network which actually handles more transactions than a midsized Costco"

You didn't say bitcoin, you said it isn't possible at all, which is obviously wrong for the reasons and numbers I gave. You haven't confronted any of that.

> It does not allow an average person to run a full node.

This doesn't matter at all. You injected this instead of backing up anything you originally said. Only miners and exchanges need to sync with the full chain. For everyone else it's a hobby.

It also is not true, again, since the numbers for bandwidth, disk space, cpu time etc are trivial and can be scaled up many orders of magnitude and still be in the realm of streaming video and decades stored on a single drive.

> I’m asking how you feel about that.

I don't feel anything since the premise is not true.

> Beyond that it’s not clear any POW coin would scale materially because it still has massive inherent inefficiencies in proof of work, which aren’t manifest in BCH at the moment because too few people use it

I think you have had it explained to you many times that mining is detached from block size. Larger blocks don't mean more mining energy is used. Proof of work or proof of stake has no bearing here, either is orthogonal to transaction throughput.

> miners not bothering to even mine

If they don't mine, they aren't miners.

> but I don’t think anything I’ve said is invalid is it

You haven't really said anything valid. Everything has been repeated assertions. You haven't explained the numbers behind anything even after all these replies.

Don't move the goalposts from the "transactions of a costco" to visa's claimed max throughput (they do about 1,700 by the way, your 24k is from estimates of the busiest hours of christmas shopping).

This is about cryptocurrencies being able to scale orders of magnitude higher than their current throughput no matter how badly you want to distort the topic to not admit your claims are ridiculous. Bitcoin's throughput is what it is because it is limited. Bitcoin cash's throughput is what it is because its 32MB blocks aren't being filled up by design.

The articles is to simplistic and the author doesn’t understand the technology.

The author claims it’s easier to mint an NFT than a currency...for all intents and purposes it’s no different to mint a erc20 token vs erc721, so the we shouldn’t pretend NFTs are somehow the lowest common denominator while “alternative currencies” are inherently complex. A shit coin is a shit going whether it represents a digital image or nothing at all other than a store of value people collectively agree on.

What everyone ignores is that not all NFTs can be described as representing a jpeg (the digital baseball card). sure many are that, but others actually include a transfer of the intellectual property they represent. Others have a “public” representation but have embedded files accessible only to the owner. Others represent ownership of digital items that can be used in various DApps across the ethereum blockchain.

And even assuming all NFTs were just digital baseball cards, if baseball cards were your thing, then I think you could acknowledge how valuable it is to be able to trace every baseball card that exists and otherwise be connected to a marketplace that include the ability to buy/trade/sell directly with other persons without a centralized authority regulating those transactions.
I disagree with the last part about direct proportionality between energy and money. But my real wonder is if we can use this hashed/mined out coins for something that is actually useful socially.(even if it is a transaction of services anonymously.) I keep wondering if we can create a crypto currency + IOT devices + energy tracking system that can value the coins you have based on the energy sources that fed into mining it. But it feels so complex that I am not optimistic about creating such a thing..

My personal advice if someone likes to care:

Get a "professional" tea cupping/tasting set. No taste altering filter methods required. My best tea related purchase ever.

Quality loose leaf tea from all over the world to develop your taste buds. Please consider that 2g/100ml is too much tea. Don't fall for hyped teas. Find tea shops willing to prepare a sample.

I got this one from a very accomplished tea master during a class he gave:

Low dosage and boiling water and long steeping. Take sips inbetween. Drink it hot or let is sit for an hour. The taste profile changes with temperature. Good teas will taste good. Bad teas will taste bad. This procedure is simple but unforgiving.

It gets even better when you tag numbers with the correct units. The calculator does type checking and automatic unit conversions. So if you key in the wrong operations, you'll either get an error somewhere along the way (from eg. trying to add something in m/s to something in m/2^2) or you'll notice the units at the end of the calculation don't match what you're supposed to end up with.

Short term view NFTs look like a scam or a joke.

Long term view we will need digital ownership especially when it comes to content or individual data/items.

When the augmented reality spectacle takes over and everyone is looking through AR glasses, rather than through a small device but through their own eyes, digital collectibles will have more value.

Shared spaces with others will have collectibles that only exist in the virtual space, but also with AR a shared virtual reality. Sitting in your room you can have layers of digital collectables that you can swap out: art, sports/gaming, music, landscapes etc that others can also see and experience. Availability and exclusivity are always part of the market and the augmented world will have similar in many areas.

Eventually consumption will have to move mostly digital with carbon neutral energy generation to prevent overuse of resources, people can collect much more in the digital space. Hoarding digital/augmented content is not as problematic as hoarding in the real world.

Everyone knows this is coming and NFTs seem to be an early iteration of digital ownership to make unique collectibles.

Making games let you know that many players just like to collect things, obsessed with it. Digital collectibles already are a massive market.

When that market changes to an augmented world, where people will share spaces virtually or play games in the real world overlaid with fun elements like games, scenery, educational content, history, events and more. This is when digital content ownership will make more sense when it comes to the unique experiences and items that people will need to make money and a market. This will only grow with more augmented spaces, events, experiences, games, entertainment, education, history and more.

Rather than tie these digital items to a platform, ownership outside the platform is better in terms of being a standard. NFTs might not be the final form, but digital content uniqueness is actually something that can help the planet once the power usage is improved or neutral. If you think about it in the long term, where more people will be viewing augmented experiences from their own eyes (Apple Glasses and more) suddenly it makes more sense, then some items may only exist in that augmented layer.
I have severe astigmatism, meaning I see double without glasses. Seven segment displays are hopeless without my glasses on.

This is why I prefer analog clock faces, and an analog watch. I can read those just fine without my glasses on. I never liked digital volt-ohm meters, either, preferring an old fashioned analog one.

Why can't NFTs be done without a blockchain? Please explain. Just add multiple hash, public/private-key cryptography, downsample discrete cosine transform, etc. You can just create a file format and a protocol. Why do you need to dump tons of CO2 into the atmosphere just for this purpose?

And while not everything in their URL spec is universally applicable, that's probably one of the good points. Nowadays, if people mean or want to allow URNs (quite rare), they'll generally explicitly specify it instead of relying on the URI term.
With ETH based NFT markets (which is the majority as far as I can tell) there seems to be a lot of sticker shock around ETH gas fees [1].

Fundamental transactions like minting new NFTs or buying/selling can be expensive depending on network conditions at the moment. It's not uncommon to see gas fees of $40-$60 to make a single NFT purchase [2].

Well, people say you can't "teleport information". That so called quantum teleportation doesn't allow superluminal signaling. So that's just a fact about how the world works, I guess.

What I'm saying is that people (who understand stuff I can't begin to comprehend) seem to dismiss out of hand an interpretation that includes nonlocality, but presumably it doesn't conflict with anything else that we actually observe whether you treat it one way or the other. It doesn't contradict all our physics with light speed limitations because it's defined consistently in the first place.

I'm just taking this on faith, but it appears that there is no issue of reality being this or that, but more of an aesthetic problem where something implying faster than light action is just unpleasant because it seems like a universal principle isn't so universal.

I want to read something popularized about what you get if you decide that an interpretation with nonlocality is just fine.
