This has been said before, I'm sure, but the problem with "The Metaverse" is that it's trying to be controlled; to be captured and caged, by a select number of corporate/quasi governmental agencies who sell themselves as "an open platform, welcome to all".

If "The Metaverse" truly is to take off, it needs to be an open standard, like HTTPS or websockets, that any virtual device can connect to and let anyone with the compute power to create their own "virtual world". And, just like the internet, it will be pretty basic at the start, and there will be disgusting sites because there will be no gatekeepers.
It's true that hydrogen is more practical for storing energy for months, but I think that storing energy for a few hours each day between daytime and nighttime (and transporting it from hot, sunny states to freezing, dark ones) is the important problem to solve.
I am. Currently the biggest commercial endeavor for it is Meta aka Facebook’s.
Can confirm /* notation still works. It comes down to how things are interpreted. The shell expands that before rm ever gets argv
Using acronyms before defining them is really unforgiveable.
My current impression of AR/VR is that is the new 3D TV: it is a futuristic-looking tech that big companies were pushing like crazy because its adoption would mean a whole new market and revenue stream to be created. Only that no one really wanted to adopt it.

The difference is that I never saw myself ever buying a 3D TV (and always hated 3D cinema), but I consider the possibility of being a late adopter of AR/VR several years from now.
I’m not so sure about that. In my country (Hungary) actually all big crimes have to go through the prime minister, he’s working together with the national bank and lots of other politicians, bankers and lawyers to steal the EU money that the country gets. Otherwise it’s a peaceful country (that is getting less peaceful as the government steals more of the economy).
Each of them wants to own the walled garden and become The platform, that's why they're not basing it on the existing open standards, conflicting commercial interests get in the way (see XKCD #927).
Agree with all points here.

An upside to using db to handle data permissions is the data has the same protections if you are accessing with direct SQL or using an app. Also, those permissions would persist with the data in restored backups.

I’m not advocating this and think for OLTP, building RBAC in the app layer is almost always a better idea, but these would be some benefits.
So, I did an easy migration of an analytics app from elasticsearch to ClickHouse: what made it easy was (a) we could replay an event stream to regenerate the database and (b) we had interfaces around the database defined in terms of the questions we needed the database to answer, and not in terms of ES-specific concepts.

But, what makes this sort of design so nice is that you can use DB-specific stuff behind the interface because you’re not trying to write all your queries in the minimally supported subset of SQL or something.
And almost all got loans backed by the US government that they won’t be able to repay and will fall on the US taxpayer to cover. Essentially USC bilked the US taxpayers out of millions, with these poor students serving as the unfortunate middlemen. Solution: make the universities have some skin the game - cover 20% of the principal on defaulted loans.
I’ve got a and old WiFi Brother label printer with AirPrint built in and I love it.

If anybody is looking for home inventory software to work with their label printer, please check out this project I’ve been working on https://www.thingybase.com/

There’s documentation for how it works with label printers at https://www.thingybase.com/help/printers. If you try it and it doesn’t work quite right with your label printer open and issue at https://github.com/thingybase/community/issues

If you’re curious all the stuff you can do with a label printer in a home setting, I’ve got a list of projects I’ve done at https://www.thingybase.com/projects
Using tax policy to push corporations and their billionaire founders/executives/shareholders to change their behavior might be the more rational strategy. For example, elimination of tax breaks for the fossil fuel sector:

> "The intangible drilling cost deduction (which expenses as opposed to capitalizes certain drilling costs) has been around for over 100 years, and the percentage depletion allowance (15% reduction in gross income of a productive well) has also been around nearly that long. (Forbes)"

This discourages investment in fossil fuels, and of course transferring the tax breaks to the renewable industry would encourage growth in that sector.

Similarly, if we went back to 1960s corporate tax rates (50% top tier), well, corporations avoided those high rates by getting deductions for their massive R&D efforts (see Bell Labs etc.). If we want technological development, encouraging large-scale private sector R&D makes sense (see China's technological development history).

Such policies don't necessarily increase government revenue but they do push corporate behavioral changes and technological development.
This is obviously true now.

But besides being government issued, tokens and the currency you talk about are both "make believe".

I mean, people valued stamps, paintings, and tulips rather high too.

I don't know how things will go, but at least these tokens seem to get quite some gobal interest lately.

Independent validation.

It's not unheard of in manufacturing for random parts to be selected for testing to ensure compliance. In fact, I'd be surprise if this supplier could get away with the same fraud with GM or Ford. One of the side effects of having suppliers design just barely adequate parts is the need to rigorously test that those parts cut only the maximally necessary corners, and not one more.
The bar example works absolutely fine for someone unfamiliar with the venue: you go to the bathroom as you normally would, and you see a sign in there that says "hey if you're in trouble do this and we will help you out", then you come back out and you do that.

There is a sweet spot between "enough people know what this signal means for it to be worth using" and "so many people know this that my adversary knows it too". The signal this kid used may be about to cross the upper threshold soon, but it worked for her.

Surreptitious and obscured communication channels have been being created and getting detected for most of human history. Look at the continuing cycle of teenage subcultures creating slang to perform the dual function of marking a member of the group and obscuring one's plans from one's parents; look at Thieves' Cant; look at histories and manuals of spycraft. And those spycraft books will probably have suggestions on what to do if you're in a situation where signals just aren't viable, too; signals are one tool.
> I get that there are a few professions where you're really going to need to know the right answer quickly without looking it up under high-pressure situations

I agree with the premise, but I think you're downplaying this quite a bit. Pretty much any job that you're not doing asynchronous work in front of a computer would apply here.

> If you elaborately cheat your way through all online classes all the way through undergrad, that seems mostly bad for you

Well it's more than bad for just you. It's bad for the university and everyone else with a degree from there since you are degrading the value of having that degree.
The question is actually mis-phrased. When people ask the question "Have you validated...", they are not asking for an absolute answer that guarantees success. They are probing whether you have actually thought deeply about what you are doing, how it will work, how it fits within the market, etc. If you haven't done that and can clearly articulate the answers, then the chances of success are orders of magnitude smaller than they otherwise would be.

The chances of success are still very small. 95%+ of startups fail. But, if you haven't done your homework, then chances of success are virtually nil.
Im surprised there is no mention of foreign data wrappers, easily one of the best but lesser known features.

> perhaps even British colonial rule was not quite so bad after all.

Blair/Orwell seemed to have this view too.

“I did not even know that the British Empire is dying, still less did I know that it is a great deal better than the younger empires that are going to supplant it.”

Their empire may have been better than some rulers, but that’s setting one very low bar.

it still doesn't solve anything. You have no way of knowing if the pixels were originally signed by the real artist or not.

The only reason it works right now is because that NFTs are so recent that you can just send a DM to artist's twitter to verify if the original set of crypto keys/wallet belong to them. When the artist himself is promoting it, it's not hard to figure out if it's genuine or not. But what happens in 10 years or if you can't trace the original artist?

How would you know if I took the picture myself or if I stole it from flicker? if reverse image search doesn't work, it would be impossible.
You cannot create duplicate NFTs. That is the whole point. The reason to have NFTs (and also fungible tokens) in games is that the gamers would know and be able to trust that the quantity of a given item was fixed. There may be more appeal to play a game where the economy was predictable and couldn't be later manipulated by the company or original game creators.
I'm sympathetic to not requiring students to install spyware on their personal computers, but I also TAed an introductory CS class for freshman engineers and, wow, there was a lot of cheating. No more than 5% of students, but it was enough where you wanted to do something about it, and remote education makes cheating on exams a lot easier.
In his autobiographical vignettes book “Surely you’re joking”…, he only really mentions several times that he solved problems that had stumped other scientists for weeks or months because apparently this technique did not get commonly used. As he described it, it was just one of his last line tools for hard integrals and he would ask stumped people if they tried it and they often said no. I think he even mentioned learning it out of a high school calculus book, but it was never covered in class.

It just wound up in his amusing self-image promoting stories, but his factual claims regarding it seem honest enough.
Are you implying you have a theory?
I highly recommend Ratio by Michael Ruhlmann. So far I've only used it for basic doughs, cakes, biscuits. Learn the ratios, and why they're like that. Very liberating.
This is what I do as well. Most schema structure is on tables that are not very large, and it's nice especially when dealing with multiple environments to prevent errors, or to produce schemas with some polymorphism or joins between several tables without a chain of id-resolving joins in-between.

There are UUID variants that can work well with indices, which shrinks the case for big-integers yet further, to micro-optimizing cases that are situational.
Headsets today are not that expensive and they're getting cheaper.

How often does migrating databases ever actually happen? I'm not saying it doesn't happen, but I've never experienced it or know anyone who has (I've asked!). I certainly would shy away from using features that make my app code cleaner and improves the all-around performance of the app on the slim-to-none chance that one day I might one day have to migrate off of postgres.

Research Edward Bernays. The nephew of of Sigmund Freud, and often referred to as the "pioneer/father of public relations/propaganda."

https://en.wikipedia.org/wiki/Edward_Bernays

He basically weaponized psychology, group psychology to be more accurate, and still in full effect today. I mean, how else do you get young women to suddenly buck societal trends and start smoking at a time it was not "proper" to do so?

Another clever trick is when the food industry started coming out with ready-made foods to prepare, like instant cake mix. This was during a time when most people cooked from scratch, and didn't trust this magical box of powder you just add water to and bake. How nutritious could that be vs baking from scratch with whole ingredients? Well, the solution was pretty clever. "Add one fresh egg." It wasn't necessary to the cake mix, but it helped women feel like they're still using real, healthy ingredients and the product stated to really take off.

I don't actually mind writing the above and adding context, but let's brainstorm some syntax that does the same thing without being verbose. How about something like:

$variable1 := try $function_call_which_returns_two_values except $variable2: $expression_which_has_error_type

which is automatically desugared to

$variable1, $variable2 := $function_call_which_returns_two_values
if $variable2 != nil {
return ($zero_values_for_other_return_types, )* $expression_which_has_error_type
}

My current apartment has Wave as one of the options, my experience is not that good and I know many Wave users are considering switching to comcast because comcast users in the same building report better uptime. We have one outage per month on average and Wave don't publish service status at all so it is almost impossible to know whether the outage is just my home router or issue in the area (you can call the support number but good luck with that when everyone else is calling the same number during an outage).

ISP monopolies are a huge problem and I find smaller ISPs tend to have better services. My previous apartment has a dedicated support team from a small ISP, and the tier 1 rep on the support line was capable of explaining the building's network topology and how they do natting.
I disagree that this is exactly the same as the stock market or the lottery. I think the fact that it is a technology that many in the tech sector missed the value of, during a time that they and only they (ie. pre-Coinbase) could have gotten involved, gives it particular sting.

Regardless of criminal activity and fraud, my main point is still that it is a new and interesting technology. No one knows what useful things it will be used for (or not) in 10 and 100 years, just like all new technologies.

Usually people on HN are positive and constructive about new techs. I observe that in the realm of crypto, people are incredibly negative, dwelling on things, like fraud and criminal activity in the present, that don't seem very important to me on a long timeline with unlimited possibilities. I am confident in the market's ability to correct those kinds of things, where there is real value.

My suspicion is those same folks wouldn't hold those opinions if they were super-lucky crypto millionaires. I think the money is causing a general lack of self-reflection in this realm: like I said, bitterness, embarrassment, and frustration. I spot those emotions in myself if I am honest.

Quest2 is $299, so actually on the scale of a very cheap phone.

Maybe some things are more tedious but some things are better. Ever more ubiquitous computing and contextual/spatial computing of AR is really interesting.

You don't get it but others find AR/VR compelling and Microsoft and FB smell money. It's worth talking about why these large companies are spending the effort.

Every time I go to a conference in SF I wind up riding the BART from SFO with the Europeans. All the other Americans (including travelers in my party who might drag me along) insist on taking a Cab, Uber, Super Shuttle, or if they have exceptionally poor judgement they rent a car from the worst car rental center in the world. (If you used that rental center you’d assume car rentals are ripe for disruption and you’d start Silvercar)
The NFT collectibles are where the action is. These are more akin to trading cards than expensive one-off art in a gallery that may have made headlines earlier this year.

Imagine that its the same trading card pools of capital that would have bought collections at MSRP, what would the seller’s annual revenue be? There had been no transparency in that. Instead, imagine if the seller only did a single set and everyone could verify that was the only one, the same amount of capital is squeezed i to that one set, which would push the price up. The issuer here makes more money from royalties when people trade pieces of the collection, instead of needing to continually issue that collection.
What you’re saying is that the artists who are currently paid for their work either will create it gratis or we can live without it. A fairly bold claim to make that this would be a worthy change, given the loss of creative work and loss of quality of life to those who create it that it would yield. Particularly when the counter argument is just to let artists produce work on their own terms, which will arguably be a better local maximum of the version of the world you advocate for and the one we have today.
>Honestly not a bad payday but how long can something like that last?

IMHO, it could be a while. Every market is different because real estate is so localized, but... there are relatively few asset classes. The general public invests in two of those: stocks and real estate. Sure, interest rates might rise but anything below 5% is a 50+ year low. Even pre Covid we were beginning to see a significant population reorganization, in part due to climate change, remote work, cost of living, and generational preferences. We simply do not have have enough housing - or enough of the right kind of housing - in areas people want to move. So, at least in my area I don't see a obvious stop to the demand.

That isn't to say that people are going to see an $80K increase in 9 months ongoing, but just that the appreciation will be there and the demand will continue.
I think for a lot of people FB is just part of the landscape, like paved roads or baseball caps. Things are the way they are and people don't ask questions. People use FB for the network effect, and because it's the status quo, not because it's technologically amazing or morally correct. Most people just don't think about it.

They've got a ton of money and billions of people more or less locked into their ecosystem. They're not being laughed out of the room because they've got a lot of what is considered a valuable resource today -- money and eyeballs / attention. In that way, they're a terrifying contender that will most likely win, even if them "winning" means creating a horrific reality for others.

Isn't HN social media, too? I scroll, open up 4 different tabs of articles to read, skim them, browse the comments, rinse and repeat. It still rewards that dopamine cycle of craving, seeking, reward, boredom, and desire to repeat the cycle again and again when facing an irritation or uncomfortable stimulus. I guess this text-based portal is just a "lite" version of social media, and even though I don't use FB or Insta, etc, this still seems to scratch the same itch.
