The article states "When that same data is transformed into a knowledge graph"

This is a non-trivial exercise. How does one transform knowledge into a knowledge graph using RDF?

RFD is extremely flexible and can represent any data and that's exactly it's great weakness. It's such a free format there is no consensus on how to represent knowledge. Many academic panels exist to set standards, but many of these efforts end up in github as unmaintained repositories.

The most important thing about RDF is that everyone needs to agree on the same modeling standards and use the same ontologies. This is very hard to achieve, and room for a lot of discussion, which makes it 'academic' :)

How is this 'enhancing individual productivity' being measured? If by self-reporting, it's worthless.

Here's a recent experiment: https://www.theregister.com/2025/09/04/m365_copilot_uk_gover...

A fairly common pattern seems to be emerging; users _believe_ that it makes them more productive, but attempts to actually measure this don't show that.

There are definitively scrapers that ignore your robots.txt file. Whether they're some "Enemy State" LLM outfit, an "Allied State" corporation outsourcing their dirty work a step or two, or just some data hoarder worried that the web as we know it is going away soon, everyone is saying they're a problem lately, I don't think everyone is lying.

But it's certainly also true that anyone feeding the scrapings to an LLM will filter it first. It's very naive of this author to think that his adlib-spun prose won't get detected and filtered out long before it's used for training. Even the pre-LLM internet had endless pages of this sort of thing, from aspiring SEO spammers. Yes, you're wasting a bit of the scraper's resources, but you can bet they're already calculating in that waste.

In the extremes, both ideas are right. In terms of timeliness, relevance, quality, rigour, variety, discussion and debate the worst content on social media is orders of magnitude worse than the worst content on mainstream media.

But the inverse is also true: the best content on social media is orders of magnitude better than the best content on mainstream media.

An individual should be able to choose what works for them, not have the government disallow swaths of sources.

There's tricks to improve the performance of pointer chasing on modern uarchs (cfr go's Greentea GC). You want to batch the address calculation/loading, deref/load and subsequent dependent ops like marking. Reorder buffers and load-store buffers are pretty big these days, so anything that breaks the addr->load->do dependency chain is a huge win, especially if there are any near that traverse loop.

> When you're young you don't really think about it much, health comes for "free."

I can't stress this enough. So many of my peers have complained about back pain and other physical ailments, as if it was an unavoidable part of turning 30.

No, it didn't just suddenly appear the moment you turned 30, it's the symptom of accumulated damage from a sedentary lifestyle.

For what it's worth, I've managed to get a lot of them into fitness, and they're doing much better now

My best experience for book reports was by oral exam in high school with a class of about 30.

Everyone has independent work and one by one you are called to the teacher's desk. He would take your book, open it up to a "random" spot and read a couple of sentences and then ask about what is going on in that scene. Hard to bull shit.

This could be modified to be like parent:teacher conferences where appointment slots exist while everyone else is doing something else (lunch, another class, maybe scheduled after hours)

> The first isn't worth arguing against: it's the idea that LLM vendors ignore your robots.txt file even when they clearly state that they'll obey it:

That’s testable and you can find content “protected” by robots.txt regurgitated by LLM’s. In practice it doesn’t matter if that’s through companies lying or some 3rd party scraping your content and then getting scraped.
by nomilk | 2025-09-05 07:27:34+00:00
Hard to argue that isn't an inconvenience. In other words, the outcome is the same, but thanks to government intervention, everyone's worse off.

A good example of where social media can really matter is for say, gay kids in a religious households, where they might not be able to talk to someone in person. Social media makes it easy to create a dummy account and visit forums for advice or reassurance.

Any sufficiently organized armed group is indistinguishable from an army. Leave them to their own devices at your own peril. They will surprise you with just how much damage they can do.

In my country, the drug gangs have grown to the point they dominate over 26% of our continental territory. They have infiltrated and corrupted every part of society, and they are showing signs of having subverted the government itself. They have a massive army of people. They are much better equipped than police. Cops cannot operate freely in their territory because they are executed on sight. As a result, our laws do not really apply to their territories.

So are they really just common criminals operating in our territories? I don't think so. They pulled off a stealth secession. The government needs to recognize this fact, grow some balls and declare war on them. Just like they declared war on and crushed last century's secessionists.

They have their own army, their own laws, even their own tribunals. They even collect taxes from their subjects and execute anyone who fails to pay them. They are a parallel government, a narcostate dictatorship made up of borderline terrorists.

You don't "police" these people. You openly declare war on them. They are enemy combatants trying to literally take over the country. Anything short of this means total defeat.

It's easy to not be radicalized if you live in a civilized nation. It's impossible when you wake up and take in the news that barbaric crime gangs dominate over a quarter of your country's territory. The thought of being at the mercy of these drug gangs is absolutely terrifying. I'm trying to raise a family here.

I was always a fan of not per stream but of percentage based minutes listened. I spend 15€ every month, take off taxes and Spotify operating expenses, which would be like 10€ left: - I listen to X 90% of my total listening minutes this month, so they get 9€.

- I listen to Y 10% of my total listening minutes this month, so they get 1€

I think this would be fair, because I kinda listen the same minutes every month, and most people with a fixed daily schedule probably do it too.

that they worked for money doesn't mean money was the only thing attached to their art. You quoted a period very different from now, where there wasn't any stupid royalty or copyright: you had to work in order to earn money, if you were a painter, that meant making new paintings.

I'm not stating that today technologies don't bring up new questions. But making silly laws that go against the nature of such technologies won't solve them.

I really like RDF in theory, as a lot of its ideas just make sense to me:

- Using URIs to clarify ambiguous IDs and terms

- EAV or subject/verb/object representation for all knowledge

- "Open world" graph where you can munge together facts from different sources

I guess using RDF specifically, instead of just inventing your own graph database with namespaced properties, means using existing RDF tooling and languages like SPARQL, OWL, SHACL etc.

Having looked into the RDF ecosystem to see if I can put something together for a side project inspired by https://paradicms.github.io, it really feels like there's a whole shed of tools out there, but the shed is a bit dingy, you can't really tell the purpose of the oddly-shaped tools you can see, nobody's organised and laid things out in a clear arrangement and, well, everything seems to be written in Java, which shouldn't be a huge issue but really isn't to my taste.

Thank you!

At this early stage, the filesystem exists only to prove the disk drivers and the IPC interfaces connecting them. I chose FAT32 for this since there has to be a FAT partition anyway for UEFI.

The concept of the VFS may stick around as a useful thing, but it’s strictly for storage, there is no “everything is a file” ethos. It’s entirely a user space concept - the kernel knows nothing of virtual filesystems, files, or the underlying hardware like disks.

you’ll note that many countries that impose capital controls have large informal economies. this is not a question of theory, there are many countries where millions of people do hold significant sums in dollars and other foreign currencies, regardless of whether they fulfill tax obligation. enough people do this and you also get the informal economy transacting in these currencies. you are “proving” the non-existence of something that in actuality is practiced by millions of people every single day.

Yet this article, like thousand others, don't go beyond binary decisions. Binary decisions are fine for many everyday decisions like figuring out whether to get insurance[1] but the Kelly criterion goes well beyond that[2] without changing the fundamentals: estimate a joint probability distribution of the outcome for each alternative, evaluate E(log X) using it, and pick the alternative for which it is highest.

For a deeper introduction, I recommend the somewhat heavy Kelly Capital Growth Investment Criterion[3] which is a well-curated collection of papers on the Kelly criterion and its various uses.

> it is still bothersome that changing a single character in a 50 megabyte presentation causes one to burn through 50 megabytes of the finite write life on the SSD.

I used to worry a lot about this but it has never once actually come up for me. 50 megabytes is a pretty extreme example, but even so if you edit this document fewer than several million times it won't matter.

Serializing the object graph all over again can be way faster than mapping into a tabular model. There are JSON serializers that can push multiple gigabytes per second per core. It might even be the case that, once you factor in the SSD controller quirks, the tabular updates could cause more blocks to be written than just dumping a big fat json stream all at once.

They should just do something like have parental controls that can configure the user agent with the user’s age, and require adult websites to not serve underage users.

It wouldn’t deter kids if you want to let them have unsupervised root access to a computer (like I enjoyed when I was 12), but I think it would be fairly effective for a walled garden like an iPhone

> I recently went on an analogue book binge, and discovered something I'd not previously noticed. Possibly for commercial reasons, books tend to frequently be much longer than they need to be, (coincidentally) they're often a minimum of 200-250 pages. Books that could easily have their content conveyed in 25 or 50 pages will be padded to 200. And not just literary trash (of which there's a lot) but books that are highly recommended reading.

I might not be a huge fan of the verbosity of Ulysses or A Song of Ice and Fire for that matter, but I also don't believe that reading is or should be an exercise in data throughput optimization, whether in fiction or non-fiction.

In fiction you set a tone, paint a picture, fill out characters, motivations, parallell arcs, etc, not to mention just appreciating the flow of prose.

In non-fiction you can explain things from various perspectives, repeat things which is crucial to learning, as well as expand something beyond the topic itself, which can make it easier to retain it when you have something already familiar to anchor it to.

> Another big disadvantage of books is you receive exactly 1 perspective. Whereas if you actively research a domain with web access, you can cross reference and absorb a variety of contrasting (/conflicting) sources, and by smashing the ideas together enough, you can figure out which arguments are strongest.

It's okay to read multiple books.

I'd say I pay 10€ per month and it gets evenly split by the artists's songs I've listened to that month.

If I only listen to one song or rather one artist. They get all the money (minus the fees for running the service).

If I listen to 100 songs by 100 artists, each gets only 10 cents (minus the blablabla).

That's how it should be, really.

Moscow had, at least at one point, 179 DGZs (Designated Ground Zeros) from the US alone - with, I would imagine, at least another 20 or so from the UK and France.

Moscow was the most overkilled places on the planet - doesn't matter if you were in a bunker - all that would do is delay your death a bit.

> How can you be so pedantic but at the same time so naive?

Wow, insulting others when you clearly have no clue what you are talking about.

In the EU a license agreement cant override your consumer rights. If the car was marketed as having a cardata feature and now that feature is restricted, under EU law you are entitled for it to be restored or fairly compensated - which could mean returning the car if it was a marketed feature and a major factor in the purchasing decision - although it’s more likely to be a monetary compensation for minor features. There’s even specific guidance for “digital elements” of products to cover things exactly like this.

I haven’t returned a car, but I have either returned or requested compensation for other consumer items for similar reasons - and was compensated fairly given their use.

An ex-gf of mine spent four years going through university to become an Occupational Therapist. She's severely dyslexic, so the university provided her with all sorts of assistance to get through her degree, from scribes in the exams to extra time for tests. She passed, and became a qualified Occupational Therapist. She landed a job in a local hospital. And on day one, was handed a huge pile of paperwork to complete. No scribes, no assistance, just "this is the job, get on with it". She failed the job, left after 3 months, spent a couple of years rethinking her entire life, and switched to a completely different career with less paperwork.

My point is that education has to be aligned with the actual world outside.

Everyone uses AI now, for all sorts of tasks. And if they don't now, they will in the next few years. Trying to exclude AI from education is not only pointless, it's doing the kids a disservice: AI is going to be a large part of their future, so it needs to be a large part of their education.

If we follow the implied course of TFA we'd reduce AI use in schools and go back to old-skool teaching methods. Then that cohort of kids would get their first job and on day one they'd be handed an AI and told "this is the job, get on with it". Like with my ex-gf, everything they were taught would be useless because the basic foundation is different.

I know education is not entirely vocational, but if it moves too far from the world of work that everyone actually spends most of their time in, then it gets too theoretical and academic. AI is part of it, education needs to change.

Twice a month is the usual trend here in the States.

This sounds like the types that enjoy a big tax refund, ignoring they had it to begin with. Unless adjusting tax withholdings, one also gives a free short term loan to Uncle Sam regardless of the cycle.

Contrived. At a point this is admitting a failure or unwillingness to budget.

Self checkout in supermarkets apparently is quite a rocky thing, some chains see profits go down after implementing them. The potential for catastrophic mistakes in LLMs is very high, like ordering 3000 big macs.

Sure in the case of 3000 big macs it would be caught by the buyer or the cooks, but ordering 6 instead of 3 will not. This will cause complaints, complaints need more people to handle, etc.

>You accept a license agreement when you buy the car which lets them pretty much do anything they want with the software.

This cannot override your rights as a consumer. If I sell you a service, I'm required to provide you that service as agreed upon at time of purchase for the duration of the contract.

Most social platforms today are optimized for content and engagement. Infinite scroll, likes, followers, algorithms — all designed to maximize attention, not connection.

But when you think about the best moments online, they usually aren’t viral videos or perfectly curated feeds. They’re the conversations: the late-night forum thread, the chat with a stranger who changed your perspective, the one honest reply in a sea of noise.

I started wondering: what if a platform was built only around that?

So I built mindfuse.io — an experiment in anonymous 1:1 voice conversations. No feeds. No algorithms. Just two people talking.

Curious what the HN community thinks:

Do you see potential in conversation-first platforms?

Or do you think feeds/content are too deeply ingrained in how people use the internet now?
by jjcob | 2025-09-05 07:41:19+00:00
People can't tell the difference in any domain. People copy what they see. It's why James Bond stopped smoking in movies, and people smoke far less now.

Mainstream porn sites show a lot of weird practices (what's up with that strangulation fetish??) and I do think it has a bad influence.

I don't think age verification is a good solution, because we don't become immune to influence at age 18. Adults are just as vulnerable to copying poor behavior as minors.

I think we should do the opposite: Remove stigma associated with sexuality. Why can't more movies just include everyday sex scenes? Why do we need to make this distinction where you need to go to a different site if you want to see something more explicit than a nipple? Most people probably wouldn't even go to porn sites if they could just watch something steamy on Netflix.

Most of us know social media is addictive. The algorithms are designed to keep us scrolling, the feeds never end, and the dopamine loops are hard to escape.

“Digital detox” is the common advice — but detox only works temporarily. People always come back, because we don’t just want less stimulation… we want connection.

That got me thinking: what if the problem isn’t technology itself, but the way it’s designed?

I decided to experiment with a different model: mindfuse.io . Instead of feeds and likes, it’s built entirely around one-on-one, anonymous voice conversations.

No followers, no algorithms, no content to binge. Just two people, talking.

Curious to hear from this community:

Do you think people are ready for connection-first platforms?

Or is the feed-based model too entrenched to break?

I wouldn't give much credence to that report, as there is no demonstrated understanding of PV site installation management principles (e.g. bright ground treatment). They deliberately highlight a worst case scenario (covering 20%+ of the entire Sahara in unmanaged high density PV) and shove a quick note at the end saying that they modeled 5% and even without other mitigations that was fine. Their model also doesn't include the carbon offsets at all, so it's absolute worst case and entirely unrealistic.

With proper site selection and albedo managed via density and bright ground treatment, you can expect net neutral local heat impact.

For me it was the other way around. In Nine Sols I got immediately stuck in the boss (mini-boss?) fight against two enemies and the flying gal.

Hollow Knight was difficult at times (Coliseum of Fools, Radiance) but it never felt unfair. Some fights (Mantis Lords, Grimm) are among the best times I've had playing a game

> Banks doing those batch jobs probably had much higher TPS than ethereum.

Yes the platform running in most banks, usually built on what we call "mainframes", is still mind blowing and with incredible performance. Also just one of those CPU is about the price of a house...

Also the requirements I cited is for running an Ethereum mainnet "Layer 1" node. And most "TPS" happens on the layer 2s anyway.

So it is hard to compare technically. But one thing for sure is becoming an active participant in the Ethereum mainnet has a very low barrier. They got rid of the whole intensive "Proof of work" part about 5 years ago. For a full sync node the waste is more at the bandwidth and disk levels.

None of that yet. The underlying SVG library, nanosvg, is very simple with no text support.

The first priority was to solve paths to pixels efficiently, including text (50,000 glyphs @ 60fps).

Gradients will be added when time allows, as I have code from a previous engine.

The coverage algorithm can be extended to support cheap box blurs, which could be used for drop shadows.
