From the second link: "Modern video games like Fortnite contain sophisticated economies that mix fungible tokens like V-Bucks with NFTs/virtual goods like skins"

Fortnite skins are different from NFTs - you're not supposed to sell them on. I just checked this with a quick Google search just in case the developer had changed how they work since I last played. They haven't, the way to sell skins is to sell your account details via an external market. Some games companies ban players from online matches who are caught buying or selling like that. I also found a site for buying /selling useful in game items, and the way that the item handover works is literally by making players meet up in game and the seller dropping the item on the floor.

VBucks are just tokens that can only be spent in Fortnite and make it slightly harder for spenders to know how much they are spending on each thing. You get them slowly in game, and can also buy them with real money. You can only use them to buy different appearances and gestures, and only from the developer.

I'd therefore argue Fortnite does not have a sophisticated economy, nor uses NFTs. It has a clever business model, using free download of the game as a whole but paid customisation, to help make it very shareable and very effective at gradually warming players up to the idea of making a purchase or five. It has become much like a shopping mall for modern teenagers - they willingly hang out there for hours for free, right next to places tempting then to purchase.
The analogy breaks down at a copied painting being hard to distinguish but a copied piece of digital art is literally impossible to distinguish, right down to its hash.

People who collect Picasso’s want the piece the artists hands truly created, that’s why copies hold no real value. By copying digital art you _are_ getting the work the artists hands created, the identical hash can prove it.
Glad you got a resolution. Google recently banned my ad account for running ads to my landing page templates and I still don't know what was wrong with that. They just gave me a bs corporate answer and that was it.
Yeah, this seems like content marketing level drivel. There isn't enough information given about important events, structural constraints and limitations, and most importantly key milestones in regulations and legal guidance made for global institutions to begin holding the asset in a compliant manner.
To me the absolute insanity of a unique digital thing in 2021 is that digital storage mediums are utterly, insanely fragile, even compared to paper, let alone a laser engraved corrosion resistant metal sheet.

I understand unique value in a Black Lotus Magic the Gathering card, which will easily outlast any digital storage media you can buy today.

Aren't we getting a little ahead of ourselves by unique digital things when there isn't even a way to store it without a global network, slurping silly amounts of energy, and of what's hardware requirements is crippling the semiconductor availability?
No Tesla turbine? I guess it would be too boring.

(I know it's bad form to explain a joke, but I'm going to anyway. The Tesla turbine used to be legendary (as in "urban legend") before the Internet. Anyway, it has only one moving part which is radially symmetrical and rotates about its center so there would be nothing to see in the animation!)
Microsoft is a crucial pillar in the US's political and industrial espionage, they won't let that happen. It wouldn't protect the US from threats, it would protect China.
That's totally a fair point; the comment wasn't supposed to be the explanation itself! But let me try without actually writing such an article.

The elements of the scattering matrix determine how two (or more) colliding particles will interact and emit zero or more particles as a result. These elements are defined by an integral that has no closed form. For certain fields (electromagnetic being the prominent example) the integral can be approximated by the sum of terms in an infinite series.

Each term in the series includes a multiplicative factor of the coupling constant (typically denoted by alpha which is approximately equal to 1/137) raised to a certain power. Since this number is quite small, the higher the power, the less the term contributes to the overall sum.

Additionally, there is a bidirectional mapping of each term in the series to a Feynman diagram (you are likely familiar with examples of these diagrams). The number of vertices in the diagram correspond to the power of the constant mentioned above. So, the terms that dominate the integral are the ones that have a small number of vertices, but you can keep going, adding more and more vertices to get a more accurate sum.

These additional vertices can be added as long as you satisfy the rules of the diagram for the particular field you are considering (different fields have different constraints on invariants that must hold at each vertex). For EM, you can add additional photon/electron vertices as long as the overall electric charge is preserved.

These additional photon edges in the diagram are "virtual" particles. Nothing more than a pictorial representation of a term in an infinite series that approximates an integral.
A few speculative ideas/thoughts:

- The US needs access to China's goods to be viable. For half a century US companies improved their efficiency/competitiveness by moving their process to China. They now have too many dependencies in the form of Chinese manufacturing and development capabilities and do not have the skills/knowledge/talents/infrastructure in the US. Because of this China can dictate their rules with zero pressure (though India and other countries will surely be a difficult competition at some point, or maybe already are).

- China owns more than 1 trillion of US debt. In the past the country bought a massive amount of US debt to inflate USD vs RMB and boost their own economy. Currently China has no reasons to sell their reserve as that would impact their economy negatively. If the US blocks them they may start massively selling US debt, which would impact USD and the US economy.

You're not missing anything. We're in the middle of an everything bubble and very dumb people are speculating on very dumb stuff. It's a casino.
Interesting, I wasn't familiar with the Whirlwind. Regarding the hardwired control in RISC designs that makes sense.

I have a somewhat tangential question - in doing some Googling about RISC and control units I came across the following from a question on Quora[1]:

>"P5 (Pentium) and P6 (Pentium Pro). Note that the control unit was phased out in favour of the reservation station and re-order buffer."

>"The control unit with its rule-based, static approach is far too simplistic and would perform poorly in an out-of-order superscalar core design where the code stream is sequential."

At first this struck me as odd as I wouldn't have thought that reservation/station and ROB would be mutually exclusive with a control unit but it got me to wondering is the microcoded control unit more of logical entity today that's split between the reservation/station and ROB? Or was this something specific to this Pentium chips. Or is this person just wrong?

It’s not really ownership though is it. The tweet is Jack’s, he can delete it if he wishes. It’s more like buying a slip of paper that says you own this particular Picasso, but the person you brought it from still has full control of it and the only thing you can do is look at it through glass like any other visitor regardless of your slip of paper.

And the whole fake/original breaks down in the physical world. How do you tie it to the physical goods in a way that can’t be fraudulent?

Why do you believe that dumping a URL, rather than substantial engagement with the article is in tune with the
HN guidelines which ask that "comments should get more thoughtful and substantive, not less, as a topic gets more divisive"?

I work at a well-known university, and I do feel strongly that the climate in academia has changed towards the worse over the last few years. The article articulates phenomena that are worth of engagement.
Ask HN: Path from business desire to first customer in your country
I am in the process of creating a platform and a community with friends for people willing to start up a company.
In France, it can be a very long way, from a wish of entrepreneurship, to an idea, quitting their job the right way, working on a business plan, finding some funds, incorporating without error, …
This is why we are creating a community to benefit one from another.

But I was wondering if people in other countries have similar difficulties, and what help they can find to help them reach incorporation, at least?

I did some searches for the US but either I cannot find the proper terms to search for, or these are no brainers for Americans, because I found none complaining of the path before being an entrepreneur, and none to offer help for such an early stage.
if businesses would not abuse cheap labor that china and other third world countries offer, we wouldn't be in this mess (or at least it wouldn't be as impactful)

besides labor costs, it doesn't make sense that an item that is bought in from X company with an HQ in Y country has to be manufactured in Z country and shipped thousands of miles to the consumer.

the amount of carbon generated from our reliance on third world countries must be ridiculously high, and wasteful.
Given that when we survey people presently, large proportions (sometimes a majority) say that they're scared to express many views, opinions, and arguments, including across most of the political spectrum, it's probably the case that this is at least starting to become a pretty big issue, even if many of its affects are still invisible.

I think because this political issue started off (and sometimes still centers upon) a lot of weird or silly fringe things, many smart people wrote it off years ago as "yeah, this is stupid and clearly a non-issue". And if you think this problem only spans the extent of what headlines various clickbait outlets may produce from it, you would perhaps even be right. But the true problem here expresses itself in a much more subtle and permeating manner: in the form of millions of people remaining silent when they wish they could instead speak up for themselves; and I can unfortunately personally state with confidence that most of the brightest and nicest people I know are a subset of this group, and their arguments are no longer heard as speaking up simply does not past even the most basic of cost/benefit analysis anymore.

Even so, this doesn't mean it is the fault of a specific institution or person. One could, as the leader of an institution, sincerely state "We will not punish anyone for speech of this nature", but yet it may do nothing to remedy the problem, since one cannot guarantee individuals won't be negatively affected in other ways.
Apple lost touch with their clients, it became the large tyrannical IBM that Steve Jobs hated so much. Companies always suffer when their quintessential soul is lost.

> In the replies of a March 2 Tesla forum post announcing the 13-day countdown until the platform’s demise, one commenter with supposed “inside info” alleged that the forums were closing because Tesla couldn’t afford to hire multiple full-time moderators to keep up with the barrage of spam and trolls that would frequent the threads.

Truly amazed at the number of companies that set up social platforms like this and then refuse to actually moderate them in any way. While it's obvious Tesla "could afford" to moderate it, it's also probably the kind of line-item no one actually considered being part of running a forum. I'm sure they think of a forum's overhead as just being hosting and maintenance, without considering the human cost of moderation until they were forced to, at which point they said "eh, fuck it."

We all talk about the moderation problem a lot with massive platforms like Facebook, but the number of people who just think "let's just throw up a small little forum/Reddit clone/Discord channel for people to talk to each other on" and then don't consider that, maybe, there might be some bad actors on there, is... I dunno, the majority, it seems.

Maybe it's because I grew up posting on forums like Something Awful that were famed for strong moderation, and IRC channels with as many ops as lurkers, but it almost seems like this was a weird forgotten aspect of building social platforms. I kinda blame the proliferation of upvotes and downvotes, which people seem to think is a replacement for moderation.
>"The System/360 covered the whole circle of application (i.e. 360°) from business to scientific."

Wow. I did not know that there was a marketing component to the name 360 I just always assumed it was just another prosaic IBM product number.
This is a seemingly compelling explanation, but I see no reason why it would actually be true.

It seems to me like it treats people as lacking the degree of intelligence and foresight needed to figure out that it's a good idea to pass building techniques along. As if back in the day people were only capable of understanding things if they were framed in a religious or supernatural way.

I just don't think people a couple of thousand years ago were so cognitively different from us. Not to mention that there's still overwhelming evidence of knowledge being passed down for non-religious purposes throughout history.

A Single Anonymous Twitter Account Caused Indigenized University to Unravel
I can't access my 13+ year old gmail account because Google now requires I verify I have access to a phone number I've never owned. There is no 2FA on this account, I know my password, and have access to the "Recovery Email" (which gets emailed a "Somebody knows your password" warning whenever I attempt to sign in to the account with my password).

I reached a real person at Google Domains and managed to get things escalated to "Specialist". Their response: "we can't help you, post about it on the community forums" (which I had already done 20 days prior).

This account "owns" digital goods, thousands of songs, and many domain names. Google is actively stealing these things, but they don't care and, "can't help".
I guess since (most of?) the creatures don't have eyes, it's easy to photograph them? Looks like the place of nightmares.
The access method approach followed in Citus is indeed lower level and more generic, which means it can be used on both time series data and other types of data.

For time series data, you can use built-in partitioning in PostgreSQL. It's not as easy to use as TimescaleDB, but pg_partman goes a long way, see:
https://docs.citusdata.com/en/latest/use_cases/timeseries.ht...

You can then use the columnar access method to compress old partitions (see the end of the doc), and use distributed tables to shard and parallelize queries and DML.

Increasing money supply though is an effect of another cause:

Amongst others, the above article cites Roche:

> In this paper I will argue why the common misconception that “inflation is always and everywhere a monetary phenomenon” cannot be used to explain most historical hyperinflations. I will argue that “money printing” is often the response to exogenous and unusual events and not the direct cause of the hyperinflation.

Further, Friedman, as a Monetarist, assumed the velocity of money is/was constant, which is definitely the case:

Tesla has resources for hundreds of engineers but not a few community managers (which they do employ, btw)? Obviously that commenter is bullshitting.
The 'oldfashioned' way was using a high pressure fuel pump, basically a needle sized piston pushing a tiny little bit of fuel into a high pressure metal fuel line, the springloaded ballbearing return valve at the tip of the injector would be pushed open by the fuel and then the fuel could stream past the ballbearing to the injector nozzle.

It's always the same story. Some guy gets on Twitter or HN who happens to get noticed, then FAANG releases a statement saying they made a "mistake". Mistakes in the aggregate that affect millions of people aren't "mistakes." That's deliberate malfeasance at scale.

Funny they never ask you that design question in interviews. "Design a system which will harm at most 5% of your users while scaling up to billions of people." Maybe if more people understood the sobering dark side of scale, they would stop gleefully promoting runaway scale-at-any-cost engineering.

This is exactly the argument I object to. As per definition, "A nation is a community of people formed on the basis of a common language, territory, history, ethnicity, or a common culture."
