One of these ways (from which Cauchy-Schwarz and the other Hilbert Space results follow) is that d_2 is the only metric that satisfies the Parallelogram Law [1]:

2 d_2(x) + 2 d_2(y) = 2 d_2(x + y) + 2 d_2(x - y)

It's a fair point; hiring is hard.

It's been a while since I had to hire outside your "people you've worked with before" bucket, but when I did, here are the two questions which worked best:

1. Tell me about a time you analysed a complex problem and came up with a solution.

2. Tell me something creative you did at work. Something you're proud of.

In my experience, a good candidate typically had excellent answers to those questions, because (1) a good candidate has had to do some real engineering at some point and they can tell you about it, and (2) a good candidate has done technical work which they're really proud of just in and of itself, and they want to tell you about it.

A technical question was useful in reducing false positives, but something a couple of steps above FizzBuzz should be fine for that. You just find out anything useful about a candidate by asking them to recreate some esoteric CS algorithm on the spot, unless you really need to select for people who can recreate esoteric CS algorithms on the spot.

It just takes one bad experience. For me it was a local kids’ dance studio. I signed up through their portal, but my daughter didn’t like it. I forgot to cancel the recurring charge for a couple of months, no response to my emails. I filed a chargeback. The next month they charged me again, so I did another instant chargeback.

They finally reached out asking why. I told them we hadn’t even shown our faces there for months. But the following month they charged me again, and again I charged it back. This cycle repeated a couple more times.

Are you sure? I am not referring to Apple’s App Store, I am only referring to the Apple Pay payment mechanism, which presumably is a relationship between the payment processor and Apple.

The bank would still be the one dealing with chargeback and chargeback related costs, I do not see why Apple would care or get involved.

However, I wonder if the biometric verification of Apple Pay merits a different response to chargebacks where the bank will not simply take the buyer’s side.

I just created an account, and the subscription page in the app shows a $50 charge, while the public pricing page shows $10 with 'Minimum 5 seats' in small letters.

Your post says about $10 charge, I am not sure how it happened with current flow.

Be very direct about the pricing, and please use your own product so customers are not confused.

> How would this be tooled? A chargeback, a deep link to the cancel page, an API connection between bank and subscription?

I'd be happy to just have the ability to easily ask the credit card company block further payments with no actual notification to the business besides that the monthly charges stop going through. If you want to be fancy about it, creat a custom industry standard declination reason for that use case.
Show HN: A browser extension to curb bad habits using the 20-second rule
by full-stack-dev | 2025-09-15 12:35:58+00:00
Hey HN. I made an extension that tries to tackles one problem: the mindless "autopilot" visits to sites that waste your time.

It applies the 20-second rule by adding a brief, intentional pause before loading a site you've marked as a distraction. Unlike a hard blocker, the goal isn't to prevent access but to enforce a conscious decision before you dive in.

The extension is free and has no ads. To see if it's actually effective, I collect a small amount of anonymous event data—like "install," "pause screen shown," and whether the user proceeded or closed the tab. No personal data, browsing history, or IP addresses are ever collected.

It's available for Chrome and Firefox (including Android). I'd love to hear your feedback on the idea.

> The implications of these geometric properties are staggering. Let's consider a simple way to estimate how many quasi-orthogonal vectors can fit in a k-dimensional space. If we define F as the degrees of freedom from orthogonality (90° - desired angle), we can approximate the number of vectors as [...]

If you're just looking at minimum angles between vectors, you're doing spherical codes. So this article is an analysis of spherical codes… that doesn't reference any work on spherical codes… seems to be written in large part by a language model… and has a bunch of basic inconsistencies that make me doubt its conclusions. For example: in the graph showing the values of C for different values of K and N, is the x axis K or N? The caption says the x axis is N, the number of vectors, but later they say the value C = 0.2 was found for "very large spaces," and in the graph we only get C = 0.2 when N = 30,000 and K = 2---that is, 30,000 vectors in two dimensions! On the other hand, if the x axis is K, then this article is extrapolating a measurement done for 2 vectors in 30,000 dimensions to the case of 10^200 vectors in 12,888 dimensions, which obviously is absurd.

I want to stay positive and friendly about people's work, but the amount of LLM-driven stuff on HN is getting really overwhelming.

The cited article is pretty clear: the M1 Max maxes out at (approximately) 100 Gb/sec per a single CPU core, 243 Gb/sec per a CPU cluster, and 409 Gb/sec per the entire SOC.

They did not (or, rather, could not) measure the theoretical peak GPU core saturation for the M1 Max SOC because such benchmarks did not exist at the time due to the sheer novelty of such wide hardware.

Yet the majority of businesses use dark patterns to avoid cancellations because it's hugely profitable to do so. Chargebacks are expensive, but the truth is that the majority of customers never leverage it, and often just endure years of paying for products they don't use. Maybe they tried to cancel to find that while they could sign up in seconds online, cancelling invariably requires a call (to a number that, wouldn't you believe it, has higher than normal call volumes!) into some maze of retention garbage.

What a world we would be if companies didn't want to bill customers that don't use their product. Imagine if companies automatically paused billing if you stopped using their product? Panacea.

Apple is a hugely greedy company, but it's one thing I like about subscribing to things in there -- I can cancel at any time with minimal effort.

Paying rent is the same as paying 100% interest. You lose everything you have paid, it counts towards nothing for you.

Paying a mortgage, you pay part amortization and part interest. Even if only 10% of your monthly payment is amortization each month, it's better than paying rent.

> If you're renting, in a market where rents are about the same or lower than mortgage interest, then you keep the leftover cash that the buyer put into their house and you can put into whatever investment you choose.

Such a market doesn't exist anywhere on this planet. Rent is always higher than mortgage + interest.

I’m confused and think I don’t get it.

If a webpage is an iceberg, the buttons and menus and dropdowns are the visible part. If I understand this page object, that’s what he proposes testing.

But the bit I care about is the bit underneath that will compose REST calls from those UI elements and sometimes make subsequent REST calls from the result of the previous ones.

That is the tricky bit to test, and the bit where we *still* fall back to manual testing and recorded demos for qa.

I was hoping this was a suggestion for a better selenium.

Cake mix is not only an American invention, predominantly sold by American companies (even in the European market), featuring traditionally American baked goods. (Pound cake, brownies and chocolate chip)

Looking for cake mix history in sweden descibe its initial import from USA and England as American style cookies and brownies became popular.

Its American association is well founded. And i did not use the word wierd. I simply pointed out that this ubiquity of "cake mix" baked goods is not reflected in my experience, and may be more concentrated in USA.

In particular in take issue with phrasing cake mix as "family recipe" as even the brands i can find at my store are younger than one generation, and has nowhere near the cultural footprint that they seem to have in USA.

Most of the special properties can be traced back to its special relationship with the inner product. And inner products have somewhat more elementary properties, so in that sense it explains the special position of the euclidean norm.

This has nothing to do with the coordinates by the way. If you want a different norm you'll first have to figure out an alternative to the bilinearity that gives the inner product its special properties.

Though bilinearity is pretty special itself, given the link between the tensor space and the linear algebra equivalent of currying.

I’m not sure you grok how big a number 10^43741 is.

If we assume that a "concept" is something that can be uniquely encoded as a finite string of English text, you could go up to concepts that are so complex that every single one would take all the matter in the universe to encode (so say 10^80 universes, each with 10^80 particles), and out of 10^43741 concepts you’d still have 10^43741 left undefined.

It feels refreshing to see someone sort of agreeing with something I've been saying for years.

I do feel the writer is missing one important aspect though: self-governance and having the decisions of humans matter. Horza Gobulchul was right. By relying on machines to do our decisions for us and having them take control of society, we lose a large part of what makes us human.

Politics in general has a lot of parallels to religion.

People need to segment into belief groups, and politics is the new church.

Only this church is a popularity game to decide who controls a vast federal standing domestic army of armed police, as well as an outward projecting armed forces. The scary thing is that everyone seems to believe their church is correct, and willing to employ the machine of violence to enforce it.

…in en-US. In en-GB, the en-dash surrounded by normal spaces, as per GP, is used where the US would use an em-dash flanked with hair spaces.

> , is this a matter of the health care system

EUs have lower chronic diseases like diabetes and hypertension than USA. Those are not diseases that have any answers in medical system so it wouldn't matter how advanced and available the system is.

For example, 40% of ppl in usa are obese vs 12% Switzerland. 50% of ppl in usa have hypertension vs 20% Swiss.

So what exactly is a medical system supposed to do if half your population is sickly and obese ?

I see this 'medical system' stuff even from very educated ppl but I feel like i am missing something. Do ppl think having access to a doctor is going prevent one from being obese ? whats the logic.

When I was a kid I used to play a bit with Celestia, but I remember I was pretty scared whilst using it... there was some kind of dread/anxiety I felt just looking at the vast void of space and something giant like Jupiter or Saturn next to it, I always thought an UFO or something was gonna pop out of nowhere.

I don't know if this feeling is common or not but I do remember reading about someone here on on Reddit feeling a similar thing, I believe it to be similar to thalassophobia.

My desktop box is running bazzite and is only used for gaming. I treat it has a console really, it isn't even connected to the internet and doesn't even receive updates unless I want to download a new game. It doesn't have any private data, the only secret I might have is that steam is already logged on but I don't have any payment account/card setup on my steam account.

Appart from the internet connection that might be useful for those gaming online I would expect most gamer machines would be like that.

Agreed with first sentence ( and only). That's why the state must legislate and fiscalize rules that benefit the population.

I don't even condemn businesses (too much). For a single business to be more eco friendly it must raise costs anf lose competitiveness. For a state to mandate these stuff, all businesses will be on the same level - and they'll have to compete for practical or cheaoet ways to be eco friendly.

It's the tragedy of the Commons, and the only way to win is to enforce rules for everyone.
by carlosjobim | 2025-09-15 12:41:03+00:00
It is clear that no matter which examples I would give you, you would not acknowledge that there are any sectors with competition. Anybody can look at any sector of their interest and see that there is competition, and it is trivially easy to do so. Including in the sectors you gave as examples. If you don't believe there is competition within fast food, then please list all the fast food companies in your country below.

Most motorcycle gangs require a 1 year hang around, plus the introduced person has to be known for at least a year.

The conventional wisdom is to wait 2 years to marry someone, and 1 year at the absolute bare minimum if you are old or at the edge of the fertility window or in some extenuating circumstance.

This seems somewhat confirmed by the fact it outlives the measure of these long-running scams. Perhaps the conventional wisdom is correct.

It can take time. It took me 8-12 months to find a job after college, and in hindsight, the pay wasn’t great (I found out later I kind of screwed myself since I didn’t know what I was worth). But over time the pay caught up thanks to a good boss I had for a while.

It’s been stable employment for a couple decades now, and let me cruise through market crashes and pandemics without any real impact on my life.

Don’t let perfect be the enemy of good. Sometimes just getting in the door is all you really need. The other stuff can work its way out later. Stability often requires patience. It’s a two way street.
by mcv | 2025-09-15 12:42:36+00:00
It seems to me that the article is missing the point somewhat. There's absolutely nothing wrong with the em-dash, but most people never use it (I don't think I've ever used it), because it doesn't appear on most standard keyboards.

If you encounter an em-dash in an online discussion, most likely someone went to extra effort to include it, or it was automatically inserted, possibly by an AI.

There are other signs that you're looking at AI-generated texts, like lists of three, a certain turn of phrase, or vague generalities, but those are easier for a human to type than an em-dash.
by bee_rider | 2025-09-15 12:42:55+00:00
I don’t think a change to using them is really all that strong of a signal, either. All the furor over using em-dashes as an AI detector might have gotten some folks to start using them.

I’m sort of surprised they haven’t always been widespread. They are great for making asides without losing energy-the voice in my head somehow has the same volume after an em-dash (unlike parentheses, which are quieter).

Bloomberg recently published around 18,000 plain text Epstein mails from his Yahoo account which led to the firing of British US ambassador and long time powerful figure in the background Lord Mandelson.

This could have been achieved at least 15 years earlier, so encryption does not seem to be the main obstacle to investigations. In some cases.

Similarly, all investigations into Epstein related JP Morgan transactions have been obstructed, for example by the firing of a Virgin Islands GA who investigated too much.

Looking forward to some EU politician tweets on these issues.

Definitely not poison. Risk of bacterial infection? Yes. I don’t know the stats on what that risk is though and for all I know perhaps it starts getting closer to zero when it’s your own farm and you are the one handling the whole process.

No citations?

“ Therefore, despite legal restrictions on benefits for legal immigrants and outright bans for unlawful immigrants, the large difference in taxes paid between native-born Americans and immigrants without high school diplomas, even those of a very young age, results in a net fiscal cost—i.e., every additional immigrant aged 18–24 without a high school diploma is expected to worsen the fiscal outlook of the United States”

> the entire universe of people you disagree with.

My comment was focused on two specific people in positions of high trust engaged in violent rhetoric who should be accountable, which is very on topic of this whole discussion. And I wouldn't be talking about Elon Musk or Donald Trump but for their positions of trusted power. If they were not the world's richest man and POTUS I wouldn't care what their rhetoric is. But because of their stations their words demand scrutiny far more than those of teachers or doctors. If we're not going to scrutinize them, I don't see why we're going after regular citizens and holding them to a higher standard.

> The scope of the discussion is much narrower than that

You’d like it to be that narrow, but you can’t circumscribe the discussion to only be about things you’re comfortable with.

> I carefully read and assessed your entire post

That may be true but no one can confirm because your dismissal consisted of a single line, a summary.

> I am stopping here because

A substantive discussion can be had but not when the rulebook is being quoted to shut it down in lieu of dialog. Cheers!

A while back I got curious and tried to do a bit of digging on this.

I looked into the Hutterites in Canada as a group that lives a somewhat similar lifestyle, but don't entirely eschew modern technology and have free access to healthcare (where-as the Amish largely self-fund as a community, and I'm not sure how much pressure that would put on _not_ using healthcare services).

In that case, the only real causes of death that showed a substantial difference from the surrounding population were the rates of cancer, and mostly the lung cancer for men and cervical cancer for women. The study didn't directly attribute it, but that would be pretty directly explained by lower rates of smoking and a lower rate of STDs (since we now know that a huge driver of cervical cancer is HPV).

BAM format is widely used but assemblies still tend to be generated and exchanged in FASTA text. BAM is quite a big spec and I think it's fair to say that none of the simpler binary equivalents to FASTA and FASTQ have caught on yet (XKCD competing standards etc.)

That's true in isolation, but is missing vital context. In the 1980s a user of proprietary Unix usually had no way to make the ls utility or a C compiler or a text editor run on an new Unix-like kernel. And even if he had the technical means to do it, he probably did not have the legal right, i.e., it would have been a violation of copyright law.

In the Unix world, there was no tradition of binary compatibility: you couldn't just take a binary compiled for NeXTSTEP and run it on Solaris or on Linux: you needed to recompile, which means you needed a C compiler and the source code for the program you want to run, and most users of Unix in the 1980s didn't have a practical way to get the source code (and if he did have access to the source code, using to to port the program to a new kernel was probably a copyright violation). Stallman could have tried to start a tradition of binary compatibility in the Unix world. That is one of the strategies he could have chosen for the GNU project: i.e., he could have picked a proprietary Unix, Solaris, say, and make sure the kernel of his GNU system could run all (or most) binaries that run on Solaris. But that strategy ran the risk that the owner of Solaris might have sued to stop this and the courts might have sided with owner, requiring the GNU project to shut down, pay the owner (Sun) a lot of money or start over with some other strategy.

Strictly, UK teaspoons are 5 ml and tablespoons 15 ml.

Well there's a rabbit hole I wasn't expecting to go down. I knew that Australian tablespoons (20 mL) were significantly different from US tablespoons. I didn't know that UK tablespoons were a whole different beast (14.2 mL), nor did I realize US tablespoons aren't quite 15 mL, and in fact my tablespoon measures are marked 15 mL. 15 mL is handily 1/16 of a US cup so it's easy enough to translate to 1/4 cup (4 tsbsp) and 1/3 cup (5 tbsp).

I appreciate your attention. Let me explain.

In the post I mentioned that we build several products. I didn’t want to list them all, because I always feel a bit awkward about self-promotion. My goal with the post was to spark a dialogue, not to advertise.

RE pricing page: yes, we do state that there’s a minimum of 5 seats. But there are no chargebacks here, since we don’t take a card upfront and we don’t bill in a hidden way. In the worst case, if you missed or didn’t read that detail, you can simply decline and not subscribe after the trial. You’ll see the price in Stripe before giving us your card. And if you prefer, you can stay on the free plan for up to 5 ppl.

That's not true. There's a whole industry of lenders for used cars. Interest rates are typically slightly higher than new cars but as long as you have a decent credit rating and the car isn't too old you can get financing.

Note that those lenders are separate from "buy here pay here" used car dealers. They offer their own in-house financing at much higher interest rates, targeting consumers with bad credit. Some of these are close to being a scam.
