* Social media (Echo chambers, propaganda bots, algorithmic content designed to get attention and emotion)

* Lowered attention spans

* A general reduction in critical thinking - instead preferring headlines, summaries, and easy answers

* Increased partisanship

* Reduction in third spaces and community connections - people becoming more isolated

* Financial stress

I'd say those are the main points. They apply in almost all developed nations, to varying extents.

Information compression and hyper-stimulation are two different things. Many forms of content online have become meaningless long form slop that could get to the point in less than 10 seconds, but are drawn out to drive view-time advertising metrics.

Fast and compressed is also a sign of intelligence rather than 'stupidity' as so many faux iconoclasts like to say. Our media storage over the last 5,000 years has most been about compression and speed, and to those who dismiss that... I dunno I guess I'll just quote Socrates succinctly "Books are for the stupid."

Tldr: Poland shot down Russian drones that entered polish airspace. Not the first time they've entered, but first time they've been shot down by Poland.

I wouldn't be surprised if it is deliberate by Russia.

Gray zone warfare in part does small little practically deniable actions, to create a new normal and establish small precedents that can be escalated into larger precedents. Slowly boil the lobster alive - create messaging that conflict in Poland is usual and nothing to wake up about.

If you wrote that 100 people could outwork one person, I'd nod my head. If you wrote that 10k people could outwork 1k people, I'd shrug. If you tell me that 100 people can combine to tie my shoe faster than I can, I'd question that.

Building a state-of-the-art search engine is not shoelaces. But upwards of 10k workers is not impressive in the right direction.

One person starting out with anything at all can quickly grow into one person with one or two really innovative ideas. One or two good ideas can catch fire pretty quickly. Don't be too dismissive.

There’s a reason why most Parisian families use a Yoyo stroller or another lightweight, foldable model: you can easily take them on the subway, and if you need help with the stairs, people are always willing to help (I’ve never seen anyone refuse).

Buses can be slow during peak hours because of traffic congestion, but during the day they’re fairly reliable and have plenty of space for strollers.

The Paris Metro is extensive, but I think you’re making very broad generalizations. It’s extremely rare (though unpleasant) to come across a drug addict, and I’ve never seen one during the day.

(Disclaimer: I live in central Paris with a newborn.)

Corporations didn't invent "them", but they definitely control them. Never mind the consortium, it's the corporations themselves who actually create the drawing that we see. And they definitely also created the typefaces that we use, like Times New Roman.

But overall, I don't think something is bad just because it's corporate. Do you think this is a bad influence of some sorts?

This hasn't been an issue for a long time because nobody uses the non-generic collections anymore. That doesn't help you with your reliance on type erasure though.

If you're up for it you should give it another try. Your example of subclassing GenericType<X> and GenericType<ConcreteClass> may be supported with covariance and contravariance in generics [1]. It's probably not very well known among C# developers (vs. basic generics) but it can make some use cases a lot easier.

I don't know what it's like now, but GitHub's internal merge queue circa 2017 was a nightmare. Every PR required you to set aside a full day of babysitting to get it getting merged/deployed - there were too many nondeterministic steps.

You'd join the queue, and then you'd have to wait for like 12 other people in front of you who would each spend up to a couple hours trying to get their merge branch to go green so it could go out. You couldn't really look away because it could be your turn out of nowhere - and you had to react to it like being on call, because the whole deployment process was frozen until your turn ended. Often that meant just clicking "retry" on parts of the CI process, but it was complicated, there were dependencies between sections of tests.

Every single thing you showed are places to publish software releases, not post your half-finished project that someone some day might find useful. We need both.

As an example, I had to reverse engineer some kinda obscure piece of hardware and after getting everything I needed for my project, I put everything on github in case it was useful to anyone. A few months later, someone was in a similar situation and built on top of my work. Neither of us made a "package" or even "a piece of software", just some badly written scripts and a scattered notes. But it was still useful to publish somewhere where others can find it, especially a place with very good SEO and code-optimized search.

That requires Wayland on the client side, doesn't it? I don't expect this to be super-practical anyway, but it's fun to see how far you can push a terminal.

I agree. It's similar to learning multiplication tables. We can all agree that math is more than endless hours of drill and kill, but there are certain skills where rote memorization is beneficial. When doing AP calculus, for example, there really just isn't time to have to work out 12 x 13 on paper or (god forbid) grab a calculator.

"The game is unapologetically hard and punishing right from the beginning." -- sorry i just dont agree with that. Mosshome is really basic. My 11 year old kid is already in citadel. Yes the game is hard but i think the community is forgetting how hard the original HK was, not to mention when Dark Souls came out it was notorious! But yes I agree silksong has its moments. Moorwing made me feel at a complete loss for a while, first time i've felt that since I was fighting Ornstein and Smough in DS1. Last Judge was also pretty difficult but felt balanced and learnable.

I guess more than anything it's just been cool to see the community come together on silksong.

Quite agree with the sentiment, and the presentation of science to the public in general. However, that probably also reflects a rather accurate assessment of scientific literacy in the general population on the part of planners.

Anyway, among US museums of natural history & science, a prominent exception is the AMNH in NYC: yes there are things for kids, but also things for "grownups". After dozens of visits I still learn something new every time.

> Getting sweaty chasing around esoteric memory management strategies

I’m advocating learning about, and understanding a couple different allocation strategies and simplifying everything by doing away with the GC and minimizing the abstractions you need.

My guess is this stuff used to be harder, but it’s now much easier with the languages and knowledge we have available. Even for application development.

> just providing an alternate perspective that life beyond the boroughs is not just strip malls.

It kind of is. Where'd you buy your charcoal? Did it have a parking lot out front and two stores on either side of it sharing the same overall building?

Of course there are exceptions, maybe you're one of them. But they are so small numerically as to be irrelevant. The vast majority of the country is living nearly all their personal life in tract housing and their commercial and social life in a strip mall. I've travelled a lot, just calling it like I see it.

Regardless of all that though, if you like it then great for you!

My comment above was just noting that city living is fine. I keep seeing in the media that NYC is scary or dangerous or something and that's fucking ridiculous, it's not.

> This exists in all communities, race is not the main problem here.

Absolutely not, this is hilariously wrong. I invite you to find any male role models in China and India (or just outside the Western hemisphere in general, for that matter) pushing such anti-intellectualism.

The male influencers here may misguide on communal lines, but you won't find anyone looking down on studying or considering it "unmanly" in any context.

Sorry for harping on it, but I think this clearly reflects the difference between 2 approaches to storing knowledge, lossy but humongous, and lossless but limited.

LLMs - Lossy highly compressed knowledge which when prompted "hallucinates" facts. LLMs hallucinations are simply how the stored information is retrieved.

Memory (human in this case) - Extremely limited, but almost always correct.

Just an observation. No morals.

I don't know. I have a hard time reading most books because they are indeed slow-paced. And by "books" I mean novels and fantasy books. But I can read an HN/Reddit discussion of several pages without a problem. Heck, sometimes I spend hours reading a specific subreddit.

I like to think that books (novels and fantasy) are low-resolution prose, so the crux of the matter is distributed — mostly useless info — across several pages. While forums — like HN or Reddit — are high-resolution prose. I don't know if I make sense.

Possibly worth considering the source: the author coaches on a mechanism for collecting and collating information. They have a vested interest in the notion you have to do the work (instead of letting the machine do it for you); indeed, they hope you do the work using this method they coach on...

(That having been said: I've used zettelkasten myself a bit and I'd say it's worth a try. Probably not for everyone but the underlying idea of "building out an artifact to supplement your memory and understanding of what you've seen" is an intriguing approach).
by AndyNemmity | 2025-09-10 17:29:42+00:00
Before the internet we asked people around us in our sphere. If we wanted to know the answer to a question, we asked, they made up an answer, and we believed it and moved on.

Then the internet came, and we asked the internet. The internet wasn't correct, but it was a far higher % correct than asking a random person who was near you.

Now AI comes. It isn't correct, but it's far higher % correct than asking a random person near you, and often asking the internet which is a random blog page which is another random person who may or may not have done any research to come up with an answer.

The idea that any of this needs to be 100% correct is weird to me. I lived a long period in my life where everyone accepted what a random person near them said, and we all believed it.

Good riddance. Libraries are totally pointless and a waste of money.

Almost every book that is available at all can be accessed within seconds on any modern digital device. You will learn how extremely valuable that is when you actually are doing research.

Students should be taught how to actually do research, not how to waste time looking things up in some small buildings which doesn't have the resources they need.
Show HN: Autonomous Computer Using Agents at Scale Controlling Real VMs
by PrateekJ17 | 2025-09-10 17:30:03+00:00
I’ve been obsessed with the idea of autonomous computer agents ever since Elon Musk tweeted about “computer control agents", I was like why am I still clicking through the same repetitive steps across machines, configs, and apps when we now have models powerful enough to just do it for us?

So I built llmhub.dev. It’s basically you can spin up on real machines. You tell them what to do, they figure out which LLM to use, and then they execute safely in a virtual machine.

Right now, every user can run up to 2 virtual machines with 5 CPU cores, 5GB RAM, and 20GB of storage each. You connect instantly with one click, no setup required. Files and apps stay right where you left them between sessions, and you can upload/download from your own machine anytime. Think of it as giving them a proper computer, not just a prompt box.

We’re still early, but I use this daily to clear out boring setup, testing, and admin flows. It’s surprisingly freeing to delegate this stuff to an agent and just check the results.

If you want to try it, shoot us an email and we’ll set you up with a free $50/month plan to play around. Would love feedback on what workflows we should add, where the safety model could be tighter, and what integrations would make this actually useful for your day to day.

> Also Netherland has a rather high amount of cars per head, so not everyone thinks like you ;-)

You can bet all those car users also ride bikes though. It's just very common in the NL to live in one city and work in another, things like that. I know people who have cars they use to go to work and back and then take all other journies via foot, bike or public transport.

In short it's not an either/or thing.

There's not a specific age where this work has to happen. Reading a variety of challenging books aloud to the class is one of the best things schoolteachers (especially early grades) can do for their students. Listening/language comprehension is incredibly important and underemphasized throughout most schooling.

Reading per se (i.e. decoding written symbols into sounds/words, at least in English or similar languages) is a quite discrete skill that takes something like 6–12 months to learn to basic proficiency, working an average of, say, 15 minutes per day with direct guidance. It has some basic pre-requisites (attention span, interest, recognizing the alphabet), but can be done at any age; some kids might be willing to learn to read at age 3 or 4, but it can certainly be started at age 8, 12, 20, or 45.

After that, speed and fluency improves with additional practice. Like anything, it's easier to get very fluent if people start younger because they have fewer other obligations. Someone who learned to read at age 4 and then spent hours reading for fun every day for 10 years is going to be far ahead of someone who learned a bit starting at age 8 but never had much help, and afterward only occasionally skimmed some magazines for the next 5 or 6 years but mostly spent their time on something else.

I soured on science media when I learned just how terrible the "journalists" and editors are.

"Scientists find super duper magic unobtanium which does mystical things that will revolutionize the world!" Click through and "Bob found a conductor with slightly lower resistance than a previous material. It's created by a 500 step process which results in an organic chain that breaks down in temps above -40C."

The issue with the medium is every day needs an exciting headline. So they make them up rather than waiting for them to come.

I think it's mostly that too much is spent on administration and middle-management type roles both in public schools and higher education. They're IMO largely a less than useful drain on funding that could be better spent elsewhere. At least as far as budgeting is concerned.

I have completely separate views on how kids are being raised and educated and how things have changed just in my half century on this planet.
Show HN: A "Codebase" as an MCP Server
by cpard | 2025-09-10 17:30:58+00:00
We built a reference MCP server that lets your editor/agent learn a codebase directly from source (signatures, types, AST, comments). Docs are optional.

The reference impl runs on our open-source project’s codebase.

Why we built it Docs are important, but they add another abstraction layer between your code and your users. Keeping them at the right quality is hard (especially at a startup), and LLM-generated docs are often mediocre until you invest real polish.

Exposing code to the model in a structured way keeps answers grounded and current, and it’s always available. You can even switch across releases/branches.

Why share this Building this for our own repo showed us how much leverage such a tool can give and how little glue you need to ship one. We did it for ourselves, but we think every repo can (and probably should) do it too.

Bigger picture In platforms/infra, “learn a new paradigm” has been an incumbent moat. LLMs + the right MCP tools can flatten that curve so more people adopt new stacks quickly and ship faster.

How to try it Hosted over HTTP [2]. With Claude Code: claude mcp add -t http fenic-docs https://mcp.fenic.ai Then ask: “What is fenic?”

For local and more prompts, see [1].

If you want to take a look at the data without running the pipeline and performing the processing + inference, check [3].

A person you respect in one field is not necessarily all-knowing within that field and, most certainly, not outside of it. This is especially true on topics that become politicized. This is not just because of the 'our side' vs 'their side' stuff, but because these issues can and have destroyed the careers of high profile people who adopt the wrong opinion.

Unlike the individuals you have cited, James Watson is a geneticist, spent his entire life studying and working on genetics, and in fact was even the person who discovered the structure of DNA. But because of his views on the genetic aspects of IQ (which inherently becomes intertwined into race, as race is just shared genetic ancestry), he was completely demonized, his career destroyed, and various honors revoked. Higher profile people speaking on these topics publicly know this all too well, so it mostly just turns into cheap virtue signaling as opposed to adding some genuine insight.

In your case, the examples they've offered are simply wrong, as would be immediately apparent with the most typical method of measuring heritability!

Sure, when you compare a "nice suburb" to a "rough area" of the city you'll come to such conclusions. But if the city you lived in is anything like mine, that disorder you experienced is likely highly localized to those "rough areas". Given this, it might be more helpful to compare a "nice suburb" to a "nice area" in a city.

I'm glad you chose the experience of taking a walk as your original example because it was instrumental in helping me to decide that I wanted to raise my family in the city.

COVID offered an opportunity for my young family to spend a month in the suburbs and the thing that sticks with me now after all these years later is how much I hated taking our then 1 year-old for a walk as compared to the city. In the suburbs we walked past the same houses on the same sidewalk-lacking streets barely seeing anyone else. If we wanted anything beyond that it required loading our toddler into the car.

Compare this to a nice area of the city where the density allows for a vast array of possible destinations and plenty of folks to smile or wave at on the way. Walks these days could be to the local park on a Saturday morning for the farmers market, or to the local Italian Ice spot because the weather hasn't gotten too cold yet. While it's still possible to have those experiences in the suburbs, it's hard to be as spontaneous when you've got to consider things like car seats and parking.

I took my 6 and 8 year old to SFMOMA and they loved it, to the point that they’ve asked to go (and have gone) to several more “boring” art museums since. We had a talk about ground rules (quiet voices, hands to self, no running, no exceptions) beforehand, and the mood of the place helped enforce those rules. A big, crowded space can be powerful in its quietness.

A lot of the weird, experimental, and experiential pieces seemed to scratch the novelty itch that they might otherwise get by running around or touching stuff. We were all ready to leave at the same time … or actually, I wanted to leave before they were ready, so it wasn’t like they got bored quickly. They are not uniquely quiet or well behaved kids, either—quite chaotic a lot of the time, really. I think a lot of people don’t give kids a chance to experience these kinds of places because they assume the kids won’t do well, which is too bad.

It was a typical attitude among my physicist and mathematician friends that memorizing was for suckers, even though it was often required to reproduce long proofs or derivations. These were people to whom mathematics came naturally; their understanding, memory, curiosity, and experience just compressed that knowledge until it was trivial to memorize. Unfortunately, many walked away with a sense of not needing to know things until they need them, but good luck with that in a systems design interview.

My biggest gripe is that art museums, especially modern art museums, play documentary/clips from documentary that last anywhere from 2 minutes to 30 minutes. Those films are not accessible anywhere else.

I would be very willing to watch them in full, but like most other visitors, I have limited time, especially when visiting a new museum in a different city. If you say observing a painting/sculpture in person is different from looking at a picture, fine, whatever, but making these videos only available in museums is sad.
