This works very well. It's super fast and responsive. But please add a gun pointing at Clippy that lets the user end him in one, clear action. I otherwise had to keep clicking through to get rid of him.

Your tech choices (WebGPU/WebAudio) make for ultra-fast load times that easily beat Kdenlive (my usual go-to editor) without even needing a download. But have you tried using Tauri to provide a "native" version?

> makes scavenging more economical and increases life span

NZ exports the front half of Hiluxes, 4runners, Prados etcetera to the Middle East.

Chop the front half off, put a bunch of em into a container, and ship them away.

I was yakking with a car wrecker the other day, and he said the above to explain why it was hard to find second-hand parts for a 1996 Prado.

1. Algebra: Let's say we have a linear operator T on a real vector space V. When trying to analyze a linear operator, a key technique is to determine the T-invariant subspaces (these are subspaces W such that TW is a subset of W). The smallest non-trivial T-invariant subspaces are always 1- or 2-dimensional(!). The first case corresponds to eigenvectors, and T acts by scaling by a real number. In the second case, there's always a basis where T acts by scaling and rotation. The set of all such 2D scaling/rotation transformations are closed under addition, multiplication, and the nonzero ones are invertible. This is the complex numbers! (Correspondence: use C with 1 and i as the basis vectors, then T:C->C is determined by the value of T(1).)

2. Topology: The fact the complex numbers are 2D is essential to their fundamentality. One way I think about it is that, from the perspective of the real numbers, multiplication by -1 is a reflection through 0. But, from an "outside" perspective, you can rotate the real line by 180 degrees, through some ambient space. Having a 2D ambient space is sufficient. (And rotating through an ambient space feels more physically "real" than reflecting through 0.) Adding or multiplying by nonzero complex numbers can always be performed as a continuous transformation inside the complex numbers. And, given a number system that's 2D, you get a key topological invariant of closed paths that avoid the origin: winding number. This gives a 2D version of the Intermediate Value Theorem: If you have a continuous path between two closed loops with different winding numbers, then one of the intermediate closed loops must pass through 0. A consequence to this is the fundamental theorem of algebra, since for a degree-n polynomial f, when r is large enough then f(r*e^(i*t)) traces out for 0<=t<=2*pi a loop with winding number n, and when r=0 either f(0)=0 or f(r*e^(i*t)) traces out a loop with winding number 0, so if n>0 there's some intermediate r for which there's some t such that f(r*e^(i*t))=0.

So, I think the point is that 2D rotations and going around things are natural concepts, and very physical. Going around things lets you ensnare them. A side effect is that (complex) polynomials have (complex) roots.

> So I wanted to get 7zip but there was no linux version.

Of course 7zip has a Linux version. I'm pretty sure it went a long time exclusively on Linux without having a Windows version. I'm also pretty sure your problem is that you were looking for a 7zip GUI because I don't even remember installing 7zip the last time I installed.

Stop using weird distros and just install Mint or something basic. If you're not a power user and you don't want to be doing power user things, don't pose as one. Mint and Ubuntu are made for handholding people who are afraid to type, and will give you tools to avoid having to do it.

Or, instead, you can realize that if you learned how to use the commandline in Linux 25 years ago, the skills you learned would still be useful. If you learned unix on a mainframe, you could still figure out what to do. It's not a wasted investment, like all of the time I wasted getting good at .BAT files.

And typing "apt install 7zip" isn't exactly hard. Or "7zip x [myfile.7z]".

Sony wasted several gigs of the very small (32g to 120g) and very expensive ssds of the time with 2 copies of a Spider Man 3 movie pre-loaded onto several different laptops. One copy in the normal installed fs, another copy in the recovery partition.

And you couldn't even watch the movie unless you also paid to unlock it.

You could delete the normal copy if you even knew it was there and then also used a disk usage util to FIND the actual file. But you couldn't do anything about the copy in the recovery image except delete the recovery partition and basically wipe & repartition the drive and do your own fresh install.

The crucial design choice is that you can't get a Doodad by just saying oh, I'm sure this is a Doodad, I will validate later. You have to parse the thing you've got to get a Doodad if that's what you meant, and the parsing can fail because maybe it isn't one.

let almost_pi: Rational = "22/7".parse().unwrap();

Here the example is my realistic::Rational. The actual Pi isn't a Rational number so we can't represent it, but 22 divided by 7 is a pretty good approximation considering.

I agree that many languages don't provide a nice API for this, but what I don't see (and maybe you have examples) is languages which do provide a nice API but call it validate. To me that naming would make no sense, but if you've got examples I'll look at them.

I... don't think you understand debanked. There is no movement OUT of your account. Deposits will be processed all day long. The intent is to tie up access to as many of your assets as possible. If you think anything of yours will just keep on going if you end up debanked, you're sadly mistaken. In addition, based on the U.S. Bank Secrecy Act as amended by the PATRIOT act, covered entities are forbidden from disclosing to you anything about why your account is frozen.

It's as close as you get to a complete shunning from modern society. You're reset to the cash you hold on you and keep custody of. And yes. In the U.S., the list that manages who can and cannot transact is centralized under OFAC. So it is at the whims of Executive whether or not any financial activity can be done with you.

Capitalism is known to have killed multiple billions world-wide.

Nearly all of the poor countries on earth are capitalist. World war 1 was a war of capitalist reorganization, Fascism was a capitalist economic system, therefore WW2 was initiated by capitalist nations. Nearly all wars being fought today are all fought by capitalists on both sides of the conflict. The poorest countries on earth are capitalists. Drug cartels are organization of drug manufacturing and transporting capitalists. Capitalist nations are proven to be the most corrupt countries on earth.

Capitalism has a vested interest in making nations poor for the sake of maximizing profits in resource extraction. Capitalism has waged more war and caused more destruction than any system before it and its only been around for ~400 years.

You really want me to believe that the system that makes money from doing heinous shit is good?

Look into the primary sources behind the things you believe to be true about communism. Many, many are very shaky and were just "cold" war propaganda pieces. I've done exactly that to come to my conclusions.

What I know to be communism, through research, and reading of primary sources, is just the natural conclusion of the democratization of society. People controlling the production they need through councils that they themselves organize into a peoples state.

Sublingual is even harder. The sublingual mucosa is thin but selective. It strongly favors molecules that are small, lipophilic and uncharged. Semaglutide is about 8-10x too big, highly polar and charged.

Injection is really the only method with any substantial bioavailability. BUT, low (<1%) bioavailability does not necessarily mean useless.

This is based on changes in trends and is somewhat of a moving target so I'll give some dates.

In the 2000s, 'forums' were forums, and 'social network' was the dominant term for products like FB and Myspace. A movie even came out with that name. Both were also 'communities'. These are verifiable on Google trends.

In the 2010s, 'social media' became the preferred term, mainly because it contrasted with 'the media' as the other major source of information available, but also because it was just an easier to use and more generic term than 'social network'. 'Forums' were still largely forums, tho like all activity online, on occasion it got lumped into 'social media'.

Sometime in the 2010s we started to delineate 'social network' from 'social media' as distinct eras of social products and properties of how the products work. This became extremely clear once the era of video took over in ~2020, as video is historically 'media' in a way that exchanging text never was.

The term 'networking' is/was its own thing and mostly unrelated to 'social networks'.

FWIW I did market analysis for Yahoo's online communities division in 06 and worked on two FB app startups, one which was a college social network, and interfaced a lot with FB in 08-12. All of these words and fine delineations were essential to my work and part of the research I was doing at the time. I looked over my notes to confirm.

It wouldn't be hacker news without a comment like this. I haven't personally worked in finance, but I've had a lot of friends do it.

I've had a couple outages due to major version upgrades: the worst was the major version update that introduced systemd, but I don't think I've ever irreparably lost a box. The main reason I like nixos now is:

1) nix means I have to install a lot fewer packages globally, which prevents accidentally using the wrong version of a package in a project.

2) I like having a version controlled record of what my systems look like (and I actually like the nix language)

> In the US, when people hear Mastercard or Visa, they usually associate that with a credit card (virtual or physical), meaning the money is not taken directly from your bank account. You pay the balance later, which gives you credit and strong dispute protections.

Europeans use these dispute protections much less, so Visa/Mastercard are mostly seen as expensive pass-throughs.

It's not about observers, but about mathematical structure and meaning. Without answering the questions, you are being ambiguous as to what the structure of C is. For example, if a particular copy of R is fixed as a subfield, then there are only two automorphisms---the trivial automorphism and complex conjugation, since any automorphism fixing the copy of R would have to be the identity on those reals and thus the rest of it is determined by whether i is fixed or sent to -i. Meanwhile, if you don't fix a particular R subfield, then there is a vast space of further wild automorphisms. So this choice of structure---that is, the answer to the questions I posed---has huge consequences on the automorphism group of your conception. You can't just ignore it and refuse to say what the structure is.

A lot of times, being organized and tidy is more about feeling good than it is about saving time.

If every time I open that drawer I'm a little frustrated, a little flustered, a little stressed, that's not just 5 seconds of "lost time" its a little bit of damage to my mood.

On the other hand, if every time I open the drawer it's all neat and organized and I can find the thing I'm looking for right away and I'm reminded of the good job I did building the organizers, that's a nice little micro-boost to my mood.

And maybe the time and effort spent figuring this out and building it and blogging about it was fun! Like a fun little hobby.

Everybody has a different temperament and different priorities, etc. Someone may look at this and think "what a waste of time". Personally, I kind of like projects like this that add a little extra satisfaction or polish to something I interact with freqently.

In the 1600s, the Indians probably had superior land-war weaponry. https://easy-history.com/the-military-revolution-in-india-pa.... By the 1700s, the British had leap-frogged the Indians by getting to iron-based canons earlier. But we’re talking incremental improvements. The point is that the Indians had a modern, gunpowder-powered military.

On the other side of the equation, the British were vastly outnumbered. Before 1800, the east india company had less than 20,000 Europeans in its army. On the other side, the Indians had hundreds of thousands of soldiers. Iron canons versus bronze canons weren’t the reason the British were able to overcome the Indian armies. It was that the EIC was able to get thousands of Indians to fight on their side, and exploited the divisions between the various Indian states.

2026 is really the year of USA going down in history.
US dollar is collapsing, its stock is having a hard time, Europe is ditching US techs like Google and Microsoft and now this.

Visa/Mastercard are the biggest evil.
Why do you think Trump got pissed at Brazil having its own payment system without Visa/Mastercard network deleting billions in revenue from Visa/Mastercard

The problem major problem is already mentioned: Each EU country wanna have their own independent system.
Nothing prevent the countries from doing that but it must talk within the same payment network so people in the Netherlands can buy from Italy using their own payment system.

Own payment system is different than payment network :)

A long time ago on HN, I said that I didn't like complex numbers, and people jumped all over my case. Today I don't think that there's anything wrong with them, I just get a code smell from them because I don't know if there's a more fundamental way of handling placeholder variables.

I get the same feeling when I think about monads, futures/promises, reactive programming that doesn't seem to actually watch variables (React.. cough), Rust's borrow checker existing when we have copy-on-write, that there's no realtime garbage collection algorithm that's been proven to be fundamental (like Paxos and Raft were for distributed consensus), having so many types of interprocess communication instead of just optimizing streams and state transfer, having a myriad of GPU frameworks like Vulkan/Metal/DirectX without MIMD multicore processors to provide bare-metal access to the underlying SIMD matrix math, I could go on forever.

I can talk about why tau is superior to pi (and what a tragedy it is that it's too late to rewrite textbooks) but I have nothing to offer in place of i. I can, and have, said a lot about the unfortunate state of computer science though: that internet lottery winners pulled up the ladder behind them rather than fixing fundamental problems to alleviate struggle.

I wonder if any of this is at play in mathematics. It sure seems like a lot of innovation comes from people effectively living in their parents' basements, while institutions have seemingly unlimited budgets to reinforce the status quo..

My views on market validation have changed with age. What I've observed after talking to hundreds of founders is that it's now so easy for someone to enter a market that it seems like those that are successful are the ones who managed to _create_ their market. No matter how smart or how good your idea is, many many successful ventures are successful because of some intangible / hard-to-reproduce circumstance that allowed them to create the market. It could be investor /pr momentum, connections, regulatory friction or some other intangible, but whatever it is - it's not something that could be easily reproduced because it's nuanced for every founder and company.

Yes, I think this is counting on the ignorance that people will believe there are "drone operators" at the console, halfway across the world, who are driving our cars [A.I. stands for "Actually Indians"?]

The way I understood the liability conversation, several years ago, was that each "autonomous vehicle" would have a corresponding operator of record, a licensed driver, who would be the responsible person for the vehicle's behavior. That there would be a designated person to carry insurance and licensing and be personally responsible and personally answer to criminal or civil charges if "their" vehicle got in a fix.

Honestly this model doesn't make any sense, as Waymo has set it up so that the only driver is the Waymo Driver making decisions, because the Waymo Driver is the only one who's privy to 100% the real-time data.

The remote CSRs, whether they're in Philippines or stateside engineers on an escalation, are explicitly not driving the car but giving it suggestions. If they need someone to "drive the car" they literally dispatch a human who gets behind the wheel, and that's how it works.

Typed functional programming has the perspective that types are like propositions and their values are proofs of that proposition. For example, the product type A * B encodes logical conjunction, and having a pair with its first element of type A and its second element of type B "proves" the type signature A * B. Similarly, the NonEmpty type encodes the property that at least one element exists. This way, the program is "correct by construction."

This types-are-propositions persoective is called the Curry-Howard correspondence, and it relates to constructive mathematics (wherein all proofs must provide an algorithm for finding a "witness" object satisfying the desired property).

The claim that you need a 10x better product to win any market share is simply incorrect, both logically and historically.

Maybe if people that bought Dell had a deep love for Dell products and were deeply integrated unable to move, but even then 10x is a waste exaggeration.

But if you have any serious academic literature that underlies this 10x claim I'm happy to take a look.

> You aren't making silicon. You are still ultimately a purveyor of other people's IP.

And neither does Dell and they are worth 80 billion $. And AMD doesn't make semiconductors, so they relay on other people IP. And TSMC doesn't make their lithographic machines or many other things, relaying on other people's IP. And all those materials relay on other people IP to be brought to market in the first place.

This is just a silly argument that for some reason puts CPU design companies as 'the real deal' and everybody else is somehow not good enough.

Historically good systems companies make just as good margin as most CPU design companies, specially those that don't have near monopolies.

> it's actually not such a good story

They are making inroads in a market that is 100s of billion $ large and people invested 300M$+ in them because they see costumer demand. If that's not good enough for you then I don't know what to tell you. I wish any of the starups I have worked at that kind of opportunity.

It seems to me you operate in a sense where anybody that doesn't go for a monopoly in a 5 trillion $ market is somehow not 'worthy' of being a startup. That just a very strange perspective on reality.

so someone passionate in ornamental gourd futures can use the passion in it to underdtand other peoples/passion or interests in it and then in the process develop your understanding of them to feed what they are looking for coming from your evolved passion now - youtube was hotornot pics to begin with!

I really know almost nothing about complex analysis, but this sure feels like what physicists call observational entropy applied to mathematics: what counts as "order" in ℂ depends on the resolution of your observational apparatus.

The algebraic conception, with its wild automorphisms, exhibits a kind of multiplicative chaos — small changes in perspective (which automorphism you apply) cascade into radically different views of the structure. Transcendental numbers are all automorphic with each other; the structure cannot distinguish e from π. Meanwhile, the analytic/smooth conception, by fixing the topology, tames this chaos into something with only two symmetries. The topology acts as a damping mechanism, converting multiplicative sensitivity into additive stability.

I'll just add to that that if transformers are implementing a renormalization group flow, than the models' failure on the automorphism question is predictable: systems trained on compressed representations of mathematical knowledge will default to the conception with the lowest "synchronization" cost — the one most commonly used in practice.
