The claim "written by AI" is not really substantiated here, and as someone who's been accused of submitting AI-generated content repeatedly recently, while that was all honestly stuff I wrote myself (hey, what can I say? I just like EM-dashes...), I sort-of sympathize?

Yes, AI slop is an issue. But throwing more AI at detecting this, and most importantly, not weighing that detection properly, is an even bigger problem.

And, HN-wise, "this seems like AI" seems like a very good inclusion in the "things not to complain about" FAQ. Address the idea, not the form of the message, and if it's obviously slop (or SEO, or self-promotion), just downvote (or ignore) and move on...

You’re picking literally the worst comparison. Atherton is almost impossible to compare to anything because houses like that are so insanely expensive to maintain and top end market size caps the value.

Literally you have no idea what you’re talking about. I mean it’s hard to imagine someone would have written this in good faith it’s so ridiculous.

This seems to be the conundrum in arguments like these — they baffle us because the comments are either quite obviously disingenuous or so radically stupid you lose hope in humanity.

Space is not much of an issue for datacenters. For one thing, compute density is growing; it's not uncommon for a datacenter to be capacity limited by power and/or cooling before space becomes an issue; especially for older datacenters.

There are plenty of data centers in urban centers; most major internet exchanges have their core in a skyscraper in a significant downtown, and there will almost always be several floors of colospace surrounding that, and typically in neighboring buildings as well. But when that is too expensive, it's almost always the case that there are satellite DCs in the surrounding suburbs. Running fiber out to the warehouse district isn't too expensive, especially compared to putting things in orbit; and terrestrial power delivery has got to be a lot less expensive and more reliable too.

According to a quick search, StarLink has one 100g space laser on equipped satellites; that's peanuts for terrestrial equipment.

In Copenhagen, the vast majority of people park their bikes on the street using only a cafe lock (frame mounted, immobilizes the rear wheel). The bikes are generally nothing special, old rusty junkers, with one or three gears. E-bikes flatten terrain but also you need an indoor place to store it and they become a magnet for theft. A cheap bike you can ride to the Metro and leave in the elements is versatile in a way e-bikes are not. (I say all this as a massive e-bike fan living in a very hilly US city who recently visited Copenhagen and adored its bike culture.)

My (paranoid) unpopular take: the AI boom we’re currently experiencing is a concerted effort by the billionaires to maintain operational agency (the ability to think and do at a massive scale) once society begins to collapse due to climate change.

~~ edit ~~

Thank you for the sane responses. I’m reconsidering how much I believe this.

Ranking Bordeaux and Nantes next to Amsterdam is nonsense.

Amsterdam is miles ahead in terms of infrastructure. This ranking dilutes the most important thing to get these results : good bike lancés everywhere with no discontinuity.

Disclaimer : I've built villes.plus, an open source automated evaluation of bike lanes. 100 points, compute itineraries in "secure" mode with Brouter between these points, count the % of secured km -> score.

Amsterdam tops at 8/10. Bordeaux is at 3/10, Nantes 2/10.

Hi, Author here!

I have been working on this project for quite some time now. Even though for such search engines, basic ideas remain the same i.e extracting meta-data or semantic info, and providing an interface to query it. Lots of effort have gone into making those modules performant while keeping dependencies minimal. Current version is down to only 3 dependencies i.e numpy, markupsafe, ftfy and a python installation with no hard dependence on any version. A lot of code is written from scratch including a meta-indexing engine and minimal vector database. Being able to index any personal data from multiple devices or service without duplicating has been the main them of the project so far!

We (My friend) have already tested it on around 180gb of Pexels dataset and upto 500k of flickr 10M dataset. Machine learning models are powered by a framework completely written in Nim (which is currently not open-source) and has ONEDNN as only dependency (which has to be do away to make it run on ARM machines!)

I have been mainly looking for feedback to improve upon some rough edges, but it has been worthwhile to work upon this project and includes code written in assembly to html !

I built this tool because I was tired of spending hours in Canva trying to turn my blog content into shareable infographics. https://ainfographic.com You paste a blog post URL or text, and it generates a visual infographic automatically. Great for repurposing content for Pinterest, LinkedIn, or adding to the blog post itself. The tool handles the layout, key points extraction, and design – so you don't need any graphic design skills. I'd love to hear your feedback and suggestions. Thanks!

Most people are internally stuck in movie logic. They can't possibly be honest with other people because they can't bring themselves to be honest with themselves.

Who wants to admit their problem with someone is that they see something in that person that they don't like in themselves and it's making them uncomfortable? Heck, if they could clear that up internally, there wouldn't be an external problem to resolve.

I am extremely forthright and literal. I am the one you can count on to come out and just mention the elephant in the room and ask why people are acting weird around it. And I can assure you this does not work. There is an entire game of communication through social nicety that completely falls apart if you ask the question out loud. You either figure out how to play it and read between (all) the lines, or you end up the awkward weirdo because you won't just let people keep their useful fictions about their discomfort with themselves.

And for all of you bristling at this, telling me it can't possibly be like that, that I'm judgmental for calling it exactly as I see it, that's exactly what I'm talking about.

We all do this. We lie to ourselves because living with our self-contradictions is unpleasant. It's much easier to ostracize the person who brings that out into the open than it is to live with our internal inconsistencies.

There is so much wrong with idealistic approach that I actively oppose “good practice cottage industry” like Uncle Bob.

Not remembering sql or details of different joins - after looking it up how much time does it take to kick back in?

I don’t remember a lot of stuff by heart but as once I worked with it I can go back rather quick, if you need it just brush it up. If you don’t need it who cares.

Polymorphism I can do stuff with it and it hurts my brain yes when I see switch statements that should be objects - but on the other hand it is much easier to understand switches or ifs for a lot of folks.

Like I totally agree with encouraging exercise most places, but let’s be careful to not understate the risks of pollution. The paper states that above 35μg/m^3 of PM2.5 pollution, the protective benefits of exercise were “non-significant” against the increased risk of cancer, and they stopped measuring at 50μg/m^3. It’s reasonable to assume that above 50, it’s a net negative to exercise outdoors.

There are lots of places in the world that exceed 35μg/m^3 PM2.5, and quite a few that exceed 50μg/m^3 PM2.5 regularly - the entire SF Bay Area is over 35 right now. Los Angeles and San Diego are both above 50 right now, as are huge swaths of Eastern Europe, Africa, and Asia... it’s a bit more than just a few handful of cities. Exercising near wildfires can be quite unhealthy too. There are places in the world where exercising outdoors is harmful to your health, but most of that is self-regulating.

The other thing to note from the paper is that even the range of 0 to 10 μg/m^3 of PM2.5 causes a 30% decrease in the benefits of exercise. That’s a pretty big reduction of benefits from exercise for the EPA’s “Good” category of air. It’s still a net positive, so you should still exercise, but just a little pollution has pretty big measurable negative effects.

Active commuting is great, you get exercise, and help reduce pollution at the same time. Even if exercise in polluted areas is beneficial, we also definitely need to keep raising awareness and improving air quality, for the time spent not exercising, for people with athsma and heart disease, for the people who can’t and/or don’t exercise. We should worry about it a little, while we exercise. ;)

I wonder if there should be levels of "in theory". Yes theoretically black body radiation exist and well stuff cools down to near background radiation via that. But the next level is theoretical implementation. Like actually moving around the heat from source and so on. Maybe this could be the spherical cow step...

Reminds me of the hyperloop. Well yes, things in vacuum tube go fast. Now does enough things go fast to make any sense...

At chess960v2.com, I'm running a full analysis of all 960 Fischer random chess starting positions using Stockfish self-play. Over 50% of the games have been completed — and while initial results looked stable, a deep review revealed a troubling anomaly: no castling occurred in any game.

The cause wasn't time pressure (0.5s per move), but a logical bug in the system: although castling was technically possible, the engine failed to recognize valid conditions during play. This distorted the data significantly, as castling is a key strategic element, especially in asymmetric setups.

The bug has now been found and fixed. A full restart with clean data is planned. The time control will be increased from 0.5s to 1 second per move — improving stability and evaluation quality, though the core issue was logical, not temporal.

The project is open-source — code is available for anyone to run longer sessions (5s, 30s, 1min+) to study position balance and fairness.

Upcoming features include online multiplayer with custom starting positions, and later, a hidden pieces mode (in development), where only pawns are shown, and players must scout to discover the true location of enemy pieces.

Brief downtime may occur in 1–2 days due to an IP address change. Feedback welcome, especially from those interested in chess asymmetry, engine-driven analysis, and novel game design.

Not the poster you're responding to, but...

I'm running OPNSense on a GMKtec G9 (a N150-based NUC with dual 2.5Gbps NICs), and a cheap managed switch. All-in, you can get it today for well under $300. Even that is rather overpowered for running my house.

The toughest component to pin down was a mesh wifi system that supports tagging VLAN segments. That's almost exclusively enterprise territory, so it's hard to find something affordable.

Palahniuk and Bourdain both talk about the fringes of 'punk' topics, but they have a totally different voice and objectives for doing so.

To me it sounds something like pairing up Brian Cox and Neil Degrasse Tyson, I mean they both talk about black holes..

For what it's worth, and i've read just about everything from both of those authors, Palahniuk is usually trying to illicit a feeling from the reader, be it disgust, ennui and nostalgia for a different time, or anger towards whatever 'the system' is at the momnent. He uses relatable anecdote to do so. His writing, in that vain, is very similar to Phillip Dick (who wrote 'a Scanner Darkly' from a lot of first-hand experiences)

Bourdain had similar prose mannerisms and favorite topics, but his objective was to instill wanderlust and an interest in the human spirit. Camaraderie, and hope for future opportunities to experience far away lands. A desire to seek more experiences regardless of what lesser prices and inconveniences must be paid in order to do so.

as a guy who grew up as a punk rocker in so-cal Palahniuk strikes me as the friend that couldn't make the show because ,even though he loves the band and the venue , there is homework due tomorrow -- whereas Bourdain always struck me as one of the folks i'd have woken up next to in someone elses' car the morning after the show and gone out to get breakfast with and talk about the night.

There is more difference between those two types of personality than I can write about, even if they gravitate around the same stuff.

I miss Bourdain.

>> Many people think they're owed more software, including fixes to software, without compensating the laborer. That worldview is the real problem.

Many people (corporations) think they're owed more money beyond the labor. This is why SaaS is a major business model these days. The marginal cost of software is zero, and yet people expect to keep getting paid for it over and over.

If you know some basic composition methods, Euler, RK and all the higher order methods can be easily constructed as you need them. But there are still many applications where you for example want to use symplectic methods instead. If you know about those+composition, you can at least solve more or less all of classical newtonian dynamics. But if you go to quantum mechanics or field theory (or quantum field theory), you need to enter a whole other world of numerics to get real world usage out of it.

> Localized phenomena like a neighbor starting a fire,

Summer evenings at home in my small Ohio village are often a health hazard, a polluted nightmare driven by the perverse compulsive ignition of so-called 'recreational' yard fires by pyromaniac neighbors.

If it is an Ozone Action day and/or a Heat Advisory day, it is near certain that one or more of the Don't Tread On Me jamokes who live nearby will come out of their houses at sunset, pile a bunch of garbage into a 55-gallon drum or a circle of rocks, sprinkle with accelerant, toss a match and back away. Eyes glazed, they'll watch for a minute, then go back inside, sometimes coming back out every ten minutes or so to refuel the fire, other times letting it blaze until the original pile is down to embers. In any case, there is a new plume of local smoke to add to the day's irritants.

It is a startling phenom to observe, let alone endure. The behavior is made all the more crazy, imho, by the presence of children. These are parents, asserting their rights to burn, and teaching their children to Live Free Or Die. It seems to me to be driven by a rebelliousness, part of the anti-woke wave, country-fried counter-culture, as in "I got your global warming right here, pard".

It's like, listening to country music stations and realizing how many (most!) contemporary and historical Country songs are themed around alcohol-worship.

But I digress.

I apologise. I was triggered by the mention of 'localized phenomena' and the horrified realization that so many of my fellow citizens are self-destructive cray-cray.

The tax situation already happens now with Intuit owning both Turbo Tax and CreditKarma to get you to sign up for credit cards.

If I were prototyping something and found I could do it cheaper somewhere else, I’m not sure I would be upset. I hate ads just for the bad user experience.

As long as it is clearly an ad and they say they have affiliations. It’s no different than what Google and Amazon does now.

But ironically enough, I was almost about to pay for Overcast years ago even though the author openly admitted that you didn’t get much of anything for it except for supporting him back then.

He then added a non slimy self hosted system to buy ads for other podcasts based on the category of podcast you were listening to at that very second (no tracking). I thought that was a great service.

I think I would actually lean into a tight integration between ChatGPT and something like booking.com[1], AirBNB, GetYourGuide, etc when looking for travel ideas.

[1] Well I personally wouldn’t because I am not as cost conscience as the average traveler and I value the loyalty programs and status of certain hotel chains and Delta airlines. But most travelers don’t and shouldn’t care.

But if they let me put in my loyalty numbers and book directly with Hyatt, Hilton and Delta, hell I might pay more for ChatGPT.

Paris being 5th when biking there is pure chaos compared to many Asian cities makes the ranking look capricious. Paris's City hall is definitely pro bike and a lot of money and effort was poured into infrastructure, but that dosn't suddenly makes it safe or largely adopted.

More generally, infrastructure isn't everything. Tokyo small streets with absolutely no markings can be way safer and bike friendlier than a bright lane in the middle of constant car traffic.

I'll note the company doing the ranking is based on Paris, so familiarity might hide many of the flaws.

That is the opposite of good. If only big companies can afford bespoke hardware, they literally become a monopoly, At home LLMs and other usages become either prohibitively expensive in purchase and running cost or you have to deal with a low quality model. Just admit that it's environmentally fucked and not open in any sense. This is not something that the community at large should strive for.

You seem to be stating this like I said something that might imply otherwise, but I can't figure it out even seeing you've got the GGGP comment. This thread kind of went off on a tangent that isn't directly addressing your original point.

But to hopefully answer your question - yes I'm in favor of wholesale importing the GDPR as-written into US law and letting the courts sort it out (sidestepping the corruption^Wlobbying process wherein corpos would make "small" edits that effectively gimp it with loopholes). I'm also in favor of antitrust enforcement against companies that anticompetitively bundle software with hardware and/or services - ie people should be able to choose software which doesn't have ads, rather than being coerced by the pressure of network effects. And if neither if those were enough to stamp out the consumer surveillance industry (aka "Big Tech") as we know it, then I'd support directly banning personalized advertising.

(I would support directly curtailing government from abusing commercial surveillance databases as well, but I don't see a straightforward meta-way to prevent that besides drastically shrinking the commercial databases to begin with)

It’s not everything, it’s just Chrome. Chrome is 1.6GB including all its dependencies. It’s going to be slow to start on any system if those dependencies aren’t preloaded.

Most Mac software I use (I don’t use Chrome) starts quickly because the dependencies (shared libraries) are already loaded. Chrome seems to have its own little universe of dependencies which aren’t shared and so have to be loaded on startup. This is the same reason Office 365 apps are so slow.

One of my favorite stories about processes and documentation:

- Work at a hedge fund

- Every evening, the whole firm "cycles" to start the next trading day

- Step 7 of 18 fails

- I document Step 7 and then show it to a bunch of folks

- I end up having a meeting where I say: "Two things are true: 1. You all agree that Step 7 is incorrectly documented. 2. You all DISAGREE on what Step 7 should be doing"

I love this story as it highlights that JUST WRITING DOWN what's happening can be a giant leap forward in terms of getting people to agree on what the process actually IS. If you don't write it down, everyone may go on basing decisions on an incorrect understanding of the system.

A related story:

"As I was writing the documentation on our market data system, multiple people told me 'You don't need to do that, it's not that complicated'. Then they read the final document and said 'Oh, I guess it is pretty complicated' "

From a pure safety point of view, it's easier to deal with older, but well-understood products, only updating them if it's an actual safety issue. The alternative is having to deal with many generations of tech, as well as permutations with other components, that could get infinitely complicated. On top of that, it's extremely time consuming and expensive to certify new components.

There's a reason the airlines and manufacturers hem and haw about new models until the economics overwhelmingly make it worthwhile, and even then it can still be a shitshow. The MCAS issue is case in point of how introducing new tech can cause unexpected issues (made worse by Boeing's internal culture).

The 787 dreamliner is also a good example of how hard it is. By all accounts is a success, but it had some serious teething problems and still has some concerns about the long term wear and tear of the composite materials (though a lot of it's problems wasn't necessarily the application of new tech, but Boeing's simultaneous desire to overcomplicate the manufacturing pipeline via outsourcing and spreading out manufacturing).

> The purely trigonometric proof that was found by some high school students recently is a great one.

I failed to understand what was so cool about that proof. It relied on concepts such as Cartesian coordinate systems, and the measure of an angle (not just a pure geometric concept), and even concepts like convergence of infinite sums, which weren't purely geometric.

Geometry had been formalized in the 20th century and had moved past informal proofs
