The benchmark was about getting the output to a pipe as fast as possible, and there's this great pipe speed hack:

// To produce output without losing speed, the program therefore needs
// to avoid copies, or at least do them in parallel with calculating
// the next block of output. This can be accomplished with the
// `vmsplice` system call, which tells the kernel to place a reference
// to a buffer into a pipe (as opposed to copying the data into the
// pipe); the program at the other end of this pipe will then be able
// to read the output directly out of this program's memory, with no
// need to copy the data into kernelspace and then back into
// userspace.

In Second Life, you could create islands with their own rules, for example you could create a car racing game. Then when you enter the game, you can not fly around while you play the game. It really was very interesting, and amazing how many things people created in a very short time span.
> why the heck am I driving a car around? I can fly, can't I?

By this logic nobody should play Gran Turismo because a Superman game exists.

> You can't test legroom or the seat cushions, because your avatar doesn't don't have a body. So I don't see how you can realistically sell an actual real-world car, because isn't most of its function and design unnecessary in the metaverse?

By this logic it's pointless to make a website to promote your car because you don't need a car to surf the web and you can't test the car by visiting the website.

The web is pretty analogous to the metaverse and the most plausible path to an actual metaverse may be an evolution of the web browser. It's the only platform with a sandbox strong enough to run completely untrusted code on your local device with no centralized gatekeeper manually enforcing rules, which I think is a hard requirement for a real metaverse. Any metaverse contender that doesn't start with that is doomed to eventual irrelevance.

But I don't think, as the author of the article seems to, that today's web is already the metaverse and nothing will change. What really drives platform change is input methods. The iPhone was a new platform because it used capacitive touch instead of mouse and keyboard, and the web evolved with it. The metaverse will be a new platform because it will use still different input methods (yet to be determined, probably not the VR controllers we use today) and the web will have to change again, perhaps more radically this time.
I'm kinda bummed out with these recent SQL tropes. Plenty of people look down on SQL and try or try to make the new fancy thing only for it to fall flat on it's face and for people to realize that SQL is pretty good. It's not great for programmatic access but it's great for analytics and manual querying.
People are willing to pay thousands of dollars on setups precisely to simulate driving a car in VR. It's not totally implausible that if the VR technology gets convincing enough it could help move some cars too.
Ada is just another programming language.
A lot of modern desktop computing (64-bit x86, SATA, PCIe, Wifi, death of Windows 9x, multicore CPUs) landed around the same time, and yes, dialup wasn't quite dead yet.

In a lot of ways, desktop computing hasn't changed much in the last 15 years. It changed way more between 1991 and 2006 than 2006 and 2021. Phones and tablets, now those are completely different.

Guilded integration?
I find it hard to see much of a serious case for NFTs, but I mostly agree with what you're saying. Even if it is a "schadenfreude generator," Amazon's attempts at having third-party sales on their site with "zshops" were a laughing stock until they weren't.
If government policy was designed so that the price of food was outstripping income growth, that would definitely be a problem.
Wouldn't there be Creative Commons licenced, remixable avatars?
One way to make money in a metaverse would be to artificially create limitations to what a user can do and then sell them the solutions to those problems. So why not add thirst and hunger meters and then sell food items? Or why not make travel non-instantaneous and then sell faster modes of transit?

This is how heavily-monetized games work today and it's not surprising that some in the industry are salivating at the thought of extending this economic model beyond just entertainment.
The notion that people paying for digital assets means that people will pay for NFTs.

It's meaningless, though, since the same (massive) caveats apply as when cryptocoins tried to claim they were a viable and better alternative to traditional financial services: buying and owning digital assets is entirely possible to handle with existing, more efficient technology.

Nobody that sells digital assets has any reason to buy into whatever purported benefits a distributed system provides other than hype: you don't need a distributed system if you already control all the servers and everyone is fine with that. The subset of customers that will be _REALLY MAD_ that they can't use their Fortnite skins should Epic disappear is vanishingly small.

NFTs don't even have the edge case that they're useful for transactions for illegal goods. It's grifters boosting bullshit trying to make a profit through and through.

Yugoslavia was so ahead of its time in so many ways. Shame it ended the way it did.
It is platform for games tailored to kids. A lot of it is essentially role play - canvas for imaginative play. A lot of it are essentially simple short games.

If they play with friends, then it all depends on who the friends are. With strangers, it is hit or miss, but overall significantly better environment then valorant, pubg or other "real" games. The stakes are lower, so toxicity is lower. But of course, we explained before hand and check on occasionally what is going on socially with them.

It is for free, but you can get stuff for money. We explained the kids we don't pay and why, so far there were no issues.

> I'm not clear on when the house as investment began.

It began when boomers entered the housing market. I.e. suddenly a lot more people wanted houses.

Before then, houses depreciated over time, like your car.
The idea of paying for an unique digital asset, even if it is just unique by social convention, would not be foreign to my kids.

If you think about it, land ownership is also just a very well established social convention.
Gotta say, I would just pirate the game and play it with a vaguely clear conscience since I've already paid for it. Probably would block it in the firewall, though.

I think my approach may well be completely lawful in some jurisdictions, since it essentially amounts to ‘making the purchased software compatible with the user's device’.

> I think that your litmus scenario should be doable with all EU banks, for PSD2 compliance.

It isn't, though.

This is my big disappointment with PSD2: it's an interoperability law for businesses, focused on enabling service providers. It doesn't help individuals directly.

PSD2 is why I can view all my accounts from different banks any one of the bank's webapp. PSD2 is why I can pay some third-party service to give me a fancy budgeting dashboard[0]. Why, were I running a nontrivial business, I could do some banking using invoicing software.

But I don't want that. They all do a shit job at this[1]. I can do better - I just need an API endpoint, preferably one that can do read-only operations and internal transfers with preauthenticated token, so I can automate most of my banking away. So my problem with PSD2 is that it didn't compel banks to give such APIs to individuals. And since it didn't, they mostly don't.

--

[0] - I could do that before PSD2, but back then, it usually involved giving them access in violation of the bank's TOS, and trusting the service won't just steal all my money.

[1] - That's not because they're bad technically, but because we have conflicting interest. The banks want me to do everything through their webapp and mobile app, because they want to upsell me more financial products. Budgeting services want me to use their UI, because this justifies subscription costs and also gives them further opportunities to surveil and monetize me. Meanwhile, all I want is to never see their inconvenient and bloated UIs. I want to run my own reports, my own analyses, my own stupid "account balance" widget, that requires no login, zero clicks, combines all accounts from all banks, and shows no advertising.

Well, I addressed the "neither easy nor hard part" upfront. My take was there has to be a solution and that too 1 solution. In other words, it had to be fair.

Second was the degree of false paths (term I made-up). This essentially governs the branching of each false path. Higher the degree higher the branching and higher the backtracking. This would make the maze harder.

So my algo was

1. To generate a valid path from top-left to bottom-right. (this is simple bfs/dfs walk). This is illustrated as path 1-2-3-4-5-6-7..-10 below. This ensures we have a fair maze.

2. Now from each number below, generate path in an outward manner till it hits walls. These are false paths. The "degree" mentioned above will dictate if there are further branching out of these paths.

1 * * * * *

2 3 * * * *

* 4 5 6 * *

* * * 7 * *

* * * 8 9 10

In the step #1 we note the row,col in a dict/hashmap. We use these in step #2 to ensure the dfs walk dont step on these row,col.

This is all I could conjure-up in 45 min including a code in python. I was labelled lean-no hire.

Edit: fixed the rendering of the maze
Text is mightier than the Metaverse.

Kids can do video calls with their smartphones but prefer texting.

We could discuss Hacker News stories with video chat but we prefer text.

News and politics junkies prefer reading text tweets on Twitter to watching talking news anchors.

Once upon a time Amazon was a company that only sold books. Dried ink on dead trees. And in the early internet age this book seller outperformed many more "forward looking visionary" startups.

Billions and billions spent on making movies as polished as possible, yet "I thought the book was better" is what we always hear.

The Metaverse will be programmed with text.

The quarterly reports outlining its financial losses will be written in text.

When journalists ultimately write its obituary, they will write text.
tbh, probably exactly how the current uni works, with vacuum energy and virtual photons communicating things in QED.

Somethings probably randomly fail, but because entropy and time is randomly selected we find ourselves in the successful ones.
but isn't it good that the standards aren't coming from Facebook, but rather will have to come from a more neutral source? I also wouldn't expect a big corp to be the one to create open standards for the rest of the community.

The way I see it, Facebook kicking off the push towards a metaverse is kind of like Bell Labs creating Unix. Sure it took a big corp with a lot of money, but that gives the rest of the community something to emulate and build off of, or decide what parts they do and don't like, and so eventually we'll have the metaverse equivalent of Linux. (edited for clarity of the first paragraph)
I don't think you understand how the value of these assets is supposed to rise. When you buy a flat in the center of town, it's supposed to increase it's value for being in the center while town is expanding. That means that there are always new housing units creating in the expanding periphery which drives population of town and therefor demand for living in the center.

The issue is that newly created housing is already priced sky high. You can blame quantitative easing which lowers interest rates and drives comodities we usually buy with credit high.

Just add another line to the graph and you'll see it.

Problem is not the market, but the fact someone is tempering with it so bad it inevitably collapses.
Instead of watching a professional driver smoothly going around a switchback, you sit in first person POV in a car that feels, handles, and accelerates better and faster than the real thing. It even cheats to make you feel like you're a better driver—that the car makes you a better driver. You probably won't buy it on the spot, but you could; the car as an impulse buy right at the peak of your high. Even if you don't, now when you see that car on the road, you associate those good memories with the car. Maybe you even go in for a test drive of the real thing.

Why would anyone want to do that rather than fly? Why would I rather play Gran Turismo when I can be Iron Man in LEGO Marvel Superheroes?
other than "older" languages in the Pascal family, there is an extended "subset" feature in Raku[0], which is pretty cool.

Amazing work, and great write up!
Cheap money (low interest rates) will cause things like real estate to inflate. If you go back 30-40 years, you wouldn’t be able to get a loan with single digit interest rates (https://www.bankrate.com/mortgages/historical-mortgage-rates...). It was normal to have to pay 10-15% interest. Purchasing power has also improved over time (https://data.worldbank.org/indicator/NY.GDP.PCAP.PP.CD?locat...). So you have more people, who are richer, and have better access to money, competing for homes. Additionally, those same people are able to afford much bigger and more expensive homes that have more features, more safety, more square footage, more everything. Isn’t it fully expected that house prices rise, particularly given the monetary policies that followed the subprime crisis?

But leaving all of that aside: if this is a debate about affordability, people can always choose to live in different places with different costs of living if they do not like their current location. That’s what is supposed to happen - a response to prices that then cools demand and causes prices to level off. No one is entitled to live in a high demand high cost of living desirable urban center at whatever price they want, doing whatever job they do. People have to either work harder or smarter to earn more and afford their dream house, or adjust to the realities of life as we all do.
I'd say a sizable majority play Gran Turismo because it's a fun test of skill -- learning the controls of an intricate machine, the layout of the game's tracks, and achieving some form of mastery over it. And I'm also sure some people play it for the fantasy of doing car racing in a safe environment, which is a very dangerous, expensive, and inaccessible sport for a lot of people.

So, perhaps I misread Tim Sweeney's point of view, but it seems like it starts and ends with "put cool car in metaverse, drive it down Main St., everyone stops and stares, like that one scene from Snow Crash. Or Ready Player One."

If it's more specific than that, "put cool car in video game, in metaverse" product placement, well we already have that today. Mercedes Benz already did a whole Mario Kart thing [0], and countless other racing games like the Forza series have sponsorships from real car companies. So that's not really anything novel for the metaverse, it's just the same product placement marketing strategy that's already existed. Tim Sweeney is basically saying "hey, look, this is the future, you can put your car in a video game" to Mercedes, who has already been doing this for years.

> By this logic it's pointless to make a website to promote your car because you can't test the car by visiting the website.

Pretty much all of these websites have a call-to-action for "Schedule a test drive at your local dealership". Hell, I remember an entire campaign from a major car corporation that was to the tune of "anybody can watch a TV commercial, but driving it is believing"

Literally the exact same answer as in the link.

Heat pumps can be up to 4-6x more efficient at heating than simple resistance based heaters.

They can expense 1 watt of energy and heat a room up by 4-6 watts of energy.

> Or you can give the middle finger to POSIX

Ok, pleas someone tell me how to use that "upvote" festure on HN :)

More on the subject, nor type nor command, nor constantly mentioned shellcheck recipe for all posixs actually do what which do - just returns path ! Looks like with some options, maybe, but it could be simply added with "which -h" - (standard *nix human readable form toggle), if -h is not already taken.

POSIX in the first place should just standarise which instead of inventing some "command".

Advice: to write best POSIX scripts write moustly-POSIX scripts and be done. Simply becose you should write big shell scripts in the first place. It is Perl job and it do it very better. And if you want more you need C and actually using system calls yourself, eg. for precise path not-globbing.

PS. Now just wait for Mr Poettering take on the subject becouse why be bothered by decades old working admins opinions or work conditions ? Or usable standards, or already working code, or not containers use cases, or just short, human friendly commandline ? Or not tangled and small codebases ?? Let's leave it to, I don't know, IBM ? Is systemd portable to AIX yet, any plans ? ;) WINDOWIZACION95 FTW
> they don't literally become totaled, the way a car or food does

Yeah, they do. When the cost of repairs and renovation get too much, the house is 'dozed and a new one built. Happens all the time.
People are discussing this design as if it is an actual design worthy of discussion. What it is is the product of a bum amateur "architect" wanting to feed his narcissism and legacy who just happens to be a billionaire. That and universities that have become slaves to money and fundraising. Charles Munger is apparently one of Buffet's cronies at Berkshire Hathaway.

It's telling that the committee was basically not involved at all and the complaints and resignation of one of the senior architects on said committee was basically dismissed without a second thought. Why even have the committee at all?

This building is an abomination about everything that is known about architecture and living spaces and flies in the face of increasing rates of student mental health issues and disorders. It's nauseating that the answer to "you're not happy inside?" is just "go outside".

Here's an except from another article I found:

> "Everybody loves light and everybody prefers natural light. But it’s a game of tradeoffs,” Munger said in an interview. “If you build a big square building, everything is conveniently near to everybody in the building. If you maximize the light, you get fewer people in the building.”

Munger is off his rocker and seems to follow a principle of maximal packing in his "designs".
But there are groupings of people by genetic markers which correlate to linguistic/cultural origin. These aren't "races" per se but they are a valid and interesting taxonomy of people. And unsurprisingly given they are determined by genetic distance, these groups tend to have a more homogenous physical appearance. When we're talking about IQ, asking "why is does it differ across identifiable groups of people?" seems to be a very controversial question to ask or attempt to answer, often getting you lumped in with the Nazis, which was my original point.

We’re seeing only the first iteration of NFTs. Gaming can be interesting. Like if WoW had some unique Legendaries in NFT form I think that would be interesting and lucrative. I’m not sure if the incentive is there for existing games because you’re giving away control of the economy. But for upstarts they can use this as a way to get players to try their game instead since you could maybe sell some of the items for real money one day
> True innovation would be more control over your money.

I mean, if you want to follow the etymology the graph root means "scrape", because you write by scratching marks into a soft surface.

Rigged Start Here: Information Pollution – A Brief History
So far, we have three basic "metaverse" approaches.

1. Augmented reality, that is, overlays on the real world. A cross between Pokemon Go and Google Glass. The Facebook version of this would probably look like that "Hyperreality" video I mention too often. This is all too likely to happen, if only to free up the hands of people who walk through the world staring at their phones. John Carmack expects it as soon as the headgear gets down to eyeglass size.

2. Virtual reality, that is, some simulated place you can visit. This may or may not involve headgear. This is really Second Life with better frame rates, or VRchat with a bigger world. It's striking that the newer metaverse wannabees have far lower visual quality than either of those. Roblox is the technical leader in this area, with a strong R&D team and a good technical roadmap. Unfortunately, their market is centered at age 13, so they censor very heavily. Holding hands is prohibited.

3. Virtual scarcity, that is, NFTs and land in virtual worlds. This is way overhyped. I expect the SEC to come down hard on a lot of that stuff soon, like they did with the ICO crowd in 2018. Selling NFTs for sports team collectables is probably OK. Selling virtual land before you build your virtual world is clearly a security, per the Howey test. The collectable NFT stuff peaked months ago. That works like Beanie Babies on eBay - $5000 asked, no bids, actual sales around $50. It turns out that OpenSea was front-running and Beeple's big sale was not arms-length. Same old scams, shiny new packaging.

I'm into the technical end of #2. This is a rather lonely place right now, even in the game development community. There are interesting problems to be solved in building large-scale virtual worlds with high-detail user content. That's not impossible, although many people think it is.
(Plug: See [1] for a demo.) The number of people actually doing anything of technical interest, as opposed to blithering about the "metaverse", is surprisingly small. I haven't even found a serious forum where such issues are discussed. I've read about a hundred of My First Metaverse Article at this point, though.
