A very simple example is that it could partially solve the problem of verifying digital identities. If I follow/friend your NFT based identity, and various virtual realms (games, social media, virtual spaces) integrate with that 'identity' NFT for user accounts, then any new virtual realm I enter, I can immediately find and connect with people I already know, or identify imposters. There will obviously still be some other hoops I need to jump through to know a digital identity maps to a particular physical person.

I could also see game studios start to issue varying tiers of rare in-game items as NFTs that can then trade on a free market, like collectible cards. Not only would I suspect people will be much more likely to pay more for digital items they can actually take uncensorable possession of (and still sell after they get banned from a game), but different studios could even make deals to make their NFT items cross compatible. (Mario NFT skins and items in Minecraft?)

Maybe I'm starry eyed and delusional, and I'm sure it's a LONG, messy road to get wherever we're going with this.
Clip – a neural network trained on a variety of (image, text) pairs
Bikes have unique serial numbers. https://bikeindex.org runs a free website to let you lookup serial numbers and mark them as stolen, and there's also various other regional websites that do a similar sort of thing.

If you want to buy a bike, make sure it has a serial number (and if the number was filed off, then yes it was probably stolen), and look it up on the index.

How would an NFT be better than the above database in any way?

I do think the bikeindex could be run better (fewer regional websites, a database we can download for archival purposes, sharing of information between multiple registries), but all of those things seem like they're easier and cheaper to do without a blockchain or NFTs.

Rather than do something like NFTs, they could do what the certificate transparency project does, and just dictate "here's the data format, here's how you share data", and get all the benefits I can think of with none of the downsides or ecological waste.

For what it's worth, there is evidence that such a database can be made and work in a similar case, since car registrations, transfers, etc are all quite well handled with no NFTs.
If you have better services, you attract more potential workers to your city. If you provide resources to educate them, you grow GDP. If you treat people like trash, then you get a bizarre dystopian landscape.
My question is did they build houses or apartments?

Because building houses generally does nothing for prices. Zoning for managed apartments is the best way to increase the housing supply.
In the Bay Area, that's some pretty powerful motivation.
In 2013, I got my iPhone 4S treated with the "Nano" protective coating from Liquipel. Not only could it survive being underwater, it could function underwater too.
Just think of all the toxic chemicals they are going to leak into the environment when they are abandoned, and the risks to groundwater. Not to mention the risk of explosion!

Wait, sorry, that’s the oil wells.
> It was also sad to see that most of their customers seemed to be residents of the nearby affordable housing buildings.

I'm no expert on the subject, but it seems that the way we manage affordable housing in the US contributes to the problem. Vienna and Singapore can teach us a lot about how to do this better:

Why didn't she back up her photos?
Youtube has been successful even though most videos are watched a dozen times or so.

NFTs are a parallel copyright system. The market price of an NFT that violates meatspace copyright law would be a function of the relevance and enforceability of the law/jurisdiction in question.

The shortcomings cited by the author are critiques of the distriution of market prices, but there is no alternative proposed. Of course most Youtube videos get a handful of views, and of course most NFTs will be nearly worthless. That concern is orthogonal to the question of whether NFTs offer some benefits over traditional copyright mechanisms.
> Facebook had a well known "buy or bury" strategy where they would either buy their competitors or try to destroy them.

That doesn't make a company monopolistic. Having a strategy that considers competitors and the whole market is just savvy thinking.

Monopoly is about the detail of how such a strategy succeeds. It isn't obvious that Facebook has a monopoly.

While I would certainly love to see Apple become more open again, Wu's book cited in the article seems to contain quite a lot of FUD, e.g. (about the early Mac):

"Generally, only Apple stuff, or stuff that Apple approved, could run on it (as software) or plug into it (as peripherals)."

Both are simply not true, there were lots of independent vendors of development tools for the early 68k Macs, the system was quite well documented (compare Inside Macintosh to today's sorry state of Documentation for macOS) and while there were no slots available, a large number of third-party peripherals for Macs existed.

Looks like Mr. Wu either has an agenda or only very superficial knowledge (or both)... not too surprising with a background as (according to Wikipedia) "attorney, legal scholar, political figure, and government official". sigh

Yes as groundbreaking as it sounds artists sell art for money in any for.and buyers buy at whatever price they think is worth it. Especially the art market is not based on fundamental valuation.
Looks amazing! But maybe it is better to ensure that canvas color is in sharp contrast to art color. I suggest using something like`hue-rotate(180)`.
Very much enjoyed the writing on this post.

Leaving yourself open to luck is a skill worth developing. Force yourself out of routines and into adventure. Look for situations with high volatility where your upside is far greater than your downside.
A less controversial way of saying this is that 10% of the cost of these wind turbines is the cost to decommission them after twenty years.

Based on quickly browsing their other headlines, though, I suspect less controversial headlines about wind power are not the goal of this organization.
An NFT is inherently decentralized, maintained by multiple independent parties, and more or less tamper-proof. That database is only as resilient as the organisation running it (or maybe less, plenty of organisations have lost their databases before), and presumably there are corruptible humans with write access to it.
Here’s my take on it
It’s a very powerful language and you can almost build anything with python. Plus its very easy to pickup as someone who’s new to programming
Huh. I've literally never had a taxi driver take a long route on me. The route I normally take (home to airport & back) is pretty simple though.

I did have one taxi driver (thanks Denver, CO!) alter the terms of the deal on me at payment time. When I questioned why the fare was higher than expected (since it was supposed to be a flat rate from the airport) he asked me how he was supposed to make money if he charged the agreed-upon rate. One of the most idiotic things I've ever heard someone in a business transaction say, and I almost told him to take a hike right there. But, my company was paying, so I figured it wasn't worth the trouble…

I don't think I've really ever had any issues with Uber/Lyft, aside from I wish I could rate drivers honestly without worrying about ending their career. They're honestly not that different from taxis…

It would be really awesome if there was a digital exchange that dealt in multi use media. I would love to be able to buy an album, image, movie, 3D model, etc directly from the creators and then own the rights to use for whatever their content license allows. And then I could then resell that content and the original content creator would get an originator fee from the transactions. Some new data formats may need to exist because I would like to share my media with my license and the content creators license/copywrite intact.
right, we should just tax carbon emissions by just enough to pay for removing those emissions, and then use said taxes to remove said emissions.
How can the contract know the actual sales price? I.e. sure, it can see a transaction, but it can't see the second transaction with the rest of the sum, or the cash that changed hands at the same time.
This is a complete misunderstanding of what an NFT does. The content isn't protected by the NFT, ownership is.
carbon emissions aren't currently paid for by the person paying for and using the electricity?
>If a government creates a law saying "anyone that processes NFTs must first put them through this list of NFTs to filter, must filter them out, etc, or go to prison", well, now NFTs are effectively erased.

Just like how the government successfully erased the drug market by making drugs illegal.
Costs aside when the author advocates an oil pipeline in place of wind we can know he's not to be taken seriously

But the decommissioning prize is mainly due to full decommission. Upgrade instead of remove and your costs would be more manageable.

Data Leverage: Empowering the Public in Its Relationship with Tech Companies
Public bathrooms smell pretty horrible, I doubt someone may feel sexually aroused in there.
I actually had a similar idea, last time the theft of a famous painting was reported in the news. The museum could offer a deal, where they get the painting back but give the thieves a certificate for it. As part of the deal, they have to hang a sign next to the painting, saying, "This painting is considered to be stolen."

The thieves can do whatever they want with the certificate -- use it to pay illicit debts and so forth. They can visit their painting at the museum, and brag to their friends about it. But the rest of the public still gets to enjoy the painting too.

Now closer to home, I'm a musician and play a modestly valuable instrument. I've thought of taking really high resolution images of it, because the grain pattern of the wood is practically like a fingerprint, and would be difficult to conceal without destroying the instrument. A database with hi-res pictures of valuable instruments would be like a serial number database for bikes.
It's another example of the title problem. You can think of it in a similar to how VINs work for cars, or ESNs work for phones. In those cases, there's a centralized database that tracks whether things are stolen or not. It's possible that NFTs could be a decent way to handle supply chain auditing of this variety, considering it's just rebirthing a process that already exists but in a more analogue form.

The advantage over something like bikeindex is that you could make the transfer process a lot more seamless. You could build things like escrowing into the protocol, so when someone sells a bike to you on craigslist, you have a nice clean transactional system which adds some nice anti-fraud measures and protections for you without necessarily requiring you to buy it from a store or marketplace to gain those protections.
Sounds like Hamsterdam from the Wire haha
The certificate transparency project has the same attributes you mention to my knowledge.

There is the problem of correct data, but I don't understand how an NFT manages to make data correct. How do I prove to the NFT that I own the bike with SN 123? How do I prove it was stolen?

I'd love if we replaced the bikeindex with a certificate transparency project-esque system and each large bike manufacturer ran an instance.

That also seems like it would be vastly easier to create than having people use the bike-stolen-registry-NFT you're talking about, and as a bonus it would be far less wasteful.
> it seems like this is going to be 90% bubble (with plenty of hucksters), and 10% real use cases that stand the test of time

All the most interesting developments in computing start like this. This is good. The future is being born now and not without the required creative destruction.
My understanding is that opening a LN channel is the same as making an on-chain transaction, which is subject to fluctuations depending on how busy the blockchain is. Right now, according to mempool, the transaction costs are around $1, which I expect would be the cost of opening a channel.

I don't know for sure, but I guess there are also some methods for opening more than one channel at once, reducing substantially the cost of opening channels when there is coordination (which could be built by a wallet app). Not entirely sure of that, though. But exciting times ahead.
>who convicted of felony murder for killing two policemen

That seems improbable. Why would anyone be charged with felony murder if they killed someone? It seems like a contradiction in terms.

Edit: to be clear, it's easy to look up that yes, his parents were convicted of felony murder, and no, they didn't kill the police officers. That's how felony murder works, so I wonder if the comment above is preaching to people who think "felony" is an intensifier for "murder" or whether it's an honest mistake.
> It really seemed like there was some sort of arrangement going on there.

There's no arrangement needed, the entire state of CA has effectively decriminalized drug possession. Getting busted for dealing with just a small stash sufficient to support a few hours of selling amounts to a slap on the wrist.

So unless the dealer is A Problem, there's not really any interest in wasting time on it. You're not putting them behind bars by catching them, you're just generating busy work for yourself as a cop, and wasting resources in general.

The same scene can be observed in any CA urban center. There is still some enforcement in the lesser populated/rural parts where police are bored and looking for reasons to mess with the lives of poor addicts though.
We have enough history to know users can't self-police. This doesn't scale. Most users don't understand the internet nearly well enough to shoulder that burden.
Check out the other "stories" this site has written about wind. The point is clearly to come up with a bad things to say about wind, and since there are not many bad points, they need to reach a bit: https://www.americanexperiment.org/?s=wind&srch_sbmt=Search
>the rotation of the disk creates shockwaves

The engineer in me cringed at this. While you can definitely use shockwaves to compress the air, dealing with the repeated stresses to the engine casing and other parts is a nightmare.

Often times it’s not, and there are other social benefits, like being invited to all the parties, etc..
It’s not simply a numbers thing.
My understanding is that the USD value attached to an NFT is just the equivalent of however much ETH is being traded. If some outside monetary platform is being used to exchange the item then the real price wouldn’t be known.
The major NFT exchanges like OpenSea and Mintable enforce it in the marketplace. But otherwise it's mostly honor system right now.
Are images/media from Wikimedia Commons included in these dumps?
That is pretty cool.

I recall recently seeing raspberry pi "cases" that mount on a din rail. I think people like modular stuff - there should be more of it.
Previously there was no way to credibly sell an "original". You can produce a commission for someone, but the nature of a digital artwork is that anyone you show it to has the whole thing.

To a certain extent this was already the case with photos, and IMO that's part of the reason that prices for photographic artwork are much lower than other media. You'll sometimes see photographers selling a series of 500 numbered prints (or whatever) as a sort of a way around that, and NFTs are kind of a more digital version of that.
I think all of this will happen, it just takes time. Crypto is entering a more mainstream and useful phase right now, but it will take another 5 to 10 years for entrepreneurs to really make the future.
I know you were being edgy with that, but there are very strict rules for decommissioning oil wells that generally consist of plugging the well with a special concrete and then removing the pipe to about 20 feet below the surface. There are considerable resources covering this if you are interested.
You're asking really good questions :)

In my layman's understanding, those are related. Playing with the piston dimensions limits (but doesn't entirely prevent) fuel/exhaust mixing. Unburned fuel in the exhaust makes them dirty.

The site says:

> ... This expels the exhaust gasses out the exhaust port, usually located on the opposite side of the cylinder. Unfortunately, some of the fresh fuel mixture is usually expelled as well.

Another factor - since the fuel enters through the crankcase, it needs to be mixed with oil for lubricating the moving parts. That oil burns when it gets to the combustion chamber. Pretty sure that also increases unwanted emissions.

It's entirely possible modern CFD and chemistry could improve on those issues... I'd be curious if anyone else knows about recent R&D on two-strokes. They're hard to beat on power-to-weight.
It's certainly ok for things to break if it is a deliberate design change. Visual regression testing in your build/deployment pipeline already can flag a change to you as part of a github merge, I don't see why we can't have similar tooling in that pipeline that focuses on efficiency.
Is there something about the conservative ideology that makes sustainable energy an enemy?

Or is it just polluting industries lobbying for more subsidies and less regulation under the conservative banner?
Whether it’s a waste of electricity is a matter of opinion. You may think it’s a waste of time and energy, others do not.

Electricity generation can come from non-polluting renewable resources (the sun, the water, the wind, etc.)

re: tiktok and clubhouse

I think the op made a good point about the Facebook m&a spree being put on hold due to their legal troubles a few years back and now can only try to clone/crush competitors now. They cloned tiktok and wouldn't be surprised to hear they have a clubhouse clone in the works.
Well, if you're operating upload without any detection filter at all, I'd say you're asking for it.

Realistically, offering an anonymous demo is probably a bad idea, no matter how many conversions it gives you.
Thanks! I assumed non-functional tests and was really confused at first.
It's also transactional if they put the work behind a centralized DRM system, yet somehow we are not pushing back against that, which to me suggests a lack of imagination.
Here I'm talking more about pseudonymous virtual identities that aren't necessarily publicly tied to meat world people. Digital passport for verification of physical world identity probably will be some government agency.

Boy would it suck if they 'accidentally' delete your digital identity and suddenly you can't participate in any social media. As more and more of our lives go virtual, this could legitimately become a prison like punishment and hopefully there's an arm of the justice system that manages that transparently.
By Indian you mean from the Republic of India and not native Americans? I am guessing do because of New Jersey.
So basically the same way it's done with traditional meatspace paintings: you make a (legal) contract stipulating it, or you rely on people to do it because they think it's right.
I remember growing up and seeing a very active “Warez” scene online, with cracks being distributed of all sorts of licensed software. Companies have since tried to make the programs “phone home” in order to check the licensec or turn them into SAAS to get revenue, but that is anathema to decentralized assets.

I haven’t looked too deeply into NFTs but it seems clear to me that:

1) NFTs are not for read access, but rather write access to a certain thing. Think Earth2 or MillionDollarHomePage or buying a domain name or some other namespace.

2) Ethereum and blockchains are entirely overkill for NFTs, because they are designed for arbitrary balances. If you want NFTs you can just have non divisible files that are collectively managed on MaidSAFE or something like that.
The data plans are crap in Canada. Most people have it setup to only backup photos on WiFi.

Sure, but that's also a relevant rebuttal to this hit piece, since it's specifically complaining that concrete (and just concrete) is left in the ground when one is removed.

> ... fall prey to invocation practicing

I am unashamedly that way with git. I don't want to learn the mental model of git, I want to accomplish some task with my files so I can go back to coding. I consult the Oracle at Google, and make the suggested incantation. The fact that there are, if I recall correctly, four different incantations for deleting a file, I consider justification for not spending more time with it than I need. Actually, I've appointed a GUI wizard to do most of the incantations for more. Just once I figured out the solution on my own. I felt like a genius. An artificial genius, because source code control shouldn't require geniosity.

In general I happen to like computers, so usually I'm usually willing to learn, but as I get older, I find I don't enjoy the prospect of 1) sit down to a task, 0) discover I have to learn something to do it, -1) read up on it, play around, 0) practice, 1) finally start my task.
Yes, to be extra clear, if that is their claim, their claim is wrong.
