smart homes dont work because wifi doesnt work. almost every user is running low quality hardware or does not deploy a meshing AP to reach the devices. the devices are not resilient to lost packets and high latency

just change a wifi ssid with smart devices in a home and watch it all crumble. users want nothing more than to get rid of “smart” once they realize its not smart enough to figure out how to change wifi networks.

endless “updates”, rent seeking, breaking changes, account setup - its not worth it.

Democratization is micro-curation. What we have now is not that. We have monolithic platforms - the richest companies in the world, or companies owned by the richest people in the world - serving content as they see fit, with a veneer of what your friends, family, and favorite celebrities want to to show you. We are back to, "Brought to you by GE!", for all intents and purposes. Right down to them telling us who to vote for.

You have to remember the "one particle in the pair fails to escape the event horizon" explanation is a simplification of the alleged reality, which is the scattering of particles (or fields) in the presence of an event horizon. As far as I know there is no intuitive, non-mathematical way to describe this accurately, so science communicators of all stripes tend to approximate it in ways that can mislead the audience.

The man himself (Hawking) said: "One might picture this negative energy flux in the following way. Just outside the event horizon there will be virtual pairs of particles, one with negative energy and one with positive energy. It should be emphasized that these pictures of the mechanism responsible for the thermal emission and area decrease are heuristic only and should not be taken too literally."

In plain javascript it's not a problem. Types are ducked so if you receive a result or a promise it doesn't matter. You can functionally work around the "color problem" using this dynamism.

It's only when you do something wacky like try to add a whole type system to a fully duck typed language that you run into problems with this. Or if you make the mistake of copying this async/await mechanism and then hamfistedly shove it into a compiled language.

Not all areas had a hiking app 10 years ago. I doubt is the case even today.

And then, if you were "different" than the average preference, you had to put the effort to select the stuff good for you. Not that different to "fighting" an algorithm.

The difference might be now that more people have a "chance" to find what they want, and "before" there was just a "specific group" that was happy. I get that "the specific group" might feel "is worse" in such a case.

Regarding the quality, I hate "following the hike" (I mean people complain about "algorithms" but then following a hike is fine ...?) - I just have some markers and look each 15 minutes on the map (which also means back and forths are not an issue).

What I would love to see more often (and maybe would fit with the use-cases described here of curation) would be finding "favorite" people and getting their "content" across applications. Like, now I can't check the google maps reviews of people that I follow on strava or on Instagram or of editors of openstreetmap... Everybody does their own little walled garden (which I am fine with) but I need to find again and again the reasonable people.

>We need open source platforms more than ever, not closed platforms behind logins

No. Not really, no. We have like 20 open source platforms already. Nobody uses most of them. The ones that people do use are extremely boring compared to any closed platform because they were created for the worst possible use of social media: letting people post their opinions online. For the average user they often lack highly requested features like making profiles private because the open source platforms decided to be decentralized as well adding enormous complexity to them. That also comes with privacy issues like making all your likes public.

People could just use Tumblr if they wanted. Text posts of any length, add as many images as you want anywhere in the post you want, share music, videos, reblog other's posts. But people don't go to Tumblr.

You could create the perfect platform but people still wouldn't use it because they are too addicted to drama, arguing online, and doomscrolling to calmly scroll through a curated catalog of music that someone spend 3 years publishing on their blog.

Lol, "responsibility" is ridiculous, in my opinion.

That appears to claim the marginalized and impotent have attractive choices to reduce their suffering. "Stop hitting yourself", -The Bully

Noone is providing adequate alternatives. "Vote for Make It All Better"... does NOT exist right now.

Humanity needs to step in, and enforce human rights in this backwards part of the world.

Before 2022, I once noticed that the Deutsche Bahn app for German trains let me put Pyongyang, the capital of North Korea, as destination. The app is good at finding international connections, but it only shows stations that are actually reachable from Germany. After some research, I found it was indeed possible to find a connection from Europe to Pyongyang via Vladivostok once per month. Not anymore though, they removed the Russian train network from their system.

Yes, it's so cringy reading a naive appeal written by someone who seemingly thinks helping our society or even just the values of open reason have anything to do with the goals of the current administration.

The loudly proclaimed surface policies are trolling for whatever draws the most attention - hence the recycling of so many disparate longstanding criticisms into an overarching wholesale condemnation. And the real policy is driven by whatever enables them to loot, steal, and otherwise enrich themselves by taking bribes for enabling corporate totalitarianism.

I guess it's not really different than people who still think the Republican party represents a strong America, or the widespread continued use of "conservative" as a lazy synonym while the actual agenda is the complete opposite of conservatism. But still like, you aren't an elderly person glued to a nursing home TV all day. You're online so much as to even have a blog. You should know better.

> We made the transition from Heathkit HDOS to CP/M

A very unusual case of a company explicitly deprecating its own proprietary OS, and shifting to an external standard, on the same hardware. Tandy giving existing Model 16 customers Xenix and shipping it with new units is the only other case I can think of offhand.

What do you think of this 1983 ACM paper comparing HDOS and CP/M? <http://delivery.acm.org/10.1145/360000/358070/p188-pechura.p...>
Show HN: I built a community job matching platform for kids with my teenagers
by toma | 2025-05-17 18:25:58+00:00
My two sons (both 17yo) and their friend (also 17yo) are interested in entrepreneurship and a potentially different, non-traditional path than what's taught in high school. They frequently find odd jobs on Nextdoor in our community but that platform does not cater to kids and can be difficult to match with someone for a job. They pitched me on an idea to create a platform specific to kids so we built a PoC. Reception in our community has been strong (Walnut Creek). Looking for feedback, and what we're missing. No monetization strategy yet, just trying to understand the market need and compelling feature set.

There aren't any hashes passing all tests that are faster than XXH3 for both short (1-32 byte) inputs and overall throughput from my reading of https://gitlab.com/fwojcik/smhasher3/-/tree/main/results#pas... . MeowHash, t1ha0.aesB, falkhash2 and falkhash1 have higher throughput and fail less tests, but they're slower on short inputs. wyhash is about the same on short inputs and fails less tests, but has half the throughput.

The way forward seems to be radically restrictive licensing and having a lawyer's phone number at hand.

I used to be a strong critic of copyright laws and fondly remember when the Internet promised to be a world of freely flowing information. These days, I think the best bet for the net to survive would be if we found a way to sue every AI company into trillions of debt and make sure that nobody ever dares freeload off the work of others, ever again.

My taste for minimalism are a bit on the extreme side. Dusk OS isn't really about having a GUI, but graphical applications such as a PDF viewer are part of its design goals.

I was planning on not having a Desktop Environment at all and just have graphical applications use the whole screen, but I was intrigued by Viewers and Texts architecture. Their fundamental simplicity is rather elegant and I feel that mixing this with Forth's own radically simple elements, there's something quite powerful to be had. I'm not sure yet how it will materialize, but I still have that feeling.

I'm not really looking to write new graphical applications for Dusk, so I'm not planning on ever needing a Oberon-based gadget framework. The idea behind Dusk is to port existing applications onto a radically simpler platform (compared to your typical POSIX) with a minimal effort, not to write new software.

"Invented" is doing a lot of legwork here. Rockets have been invented in China in the 13th century, if not earlier. Hwacha ("fire cars") were more advanced than that, since they were an early version of an MLRS which could fire over a hundred rocket arrows at once. But Chinese Huoche (the same word with the same meaning) seems to predate Hwacha, introduced probably somewhere in the late 14th century[1].

Hwachas were probably more of a further development of the earlier Huoche than a completely new invention.

Naw, this is Hawking Radiation a "quantum phenomena" that in the original paper doesn't conserve mass/baryons. It's weird that it was originally published (fantastic claims require fantastic evidence). I don't really like the headline of TFA either since it seems conflate all sorts of radiation.

The original paper is 2023 (Phys Review Letters). There was a rebuttal in PRL in 2024. I don't know why this is still a big deal now in 2025 other than Science Alert decided to write (another?) hyperbolic article based on crap. Still boring.

If you find the project interesting, a star on repo would mean a lot for me! It took quite a bit of time and effort to bring it to life.

Hey everyone! This project started out as a personal experiment in low-level graphics, but turned into a bit of a long-term journey. I originally began working on it quite a while ago, but had to put it on hold due to the complexity of the math involved - and because I was studying full-time at the same time.

objcurses is a minimalistic 3D viewer for .obj models that runs entirely in terminal. It renders models in real time using a retro ASCII approach, supports basic material colors from .mtl files, and simulates simple directional lighting.

The project is written from scratch in modern C++20 using ncurses, with no external graphic engines or frameworks - just raw math, geometry and classic C library for terminal interaction.

Also happy to hear any feedback, especially on performance, rendering accuracy, or usability.

At some point, I might also organize the notes I took during development and publish them as an article on my website - if I can find the time and energy :)

MCP is supposed to support both concepts of a local and a remote server, but in practice most have opted to build local servers and the tooling basically only supports that which is a shame and, in my opinion, a nonsensical choice that basically only has downsides (you need to maintain the local server, your customers need to install it, you have to remain retro-compatible with your local server, etc.).

This just continues to reinforce my feeling that everything around vibe coding and GenAI-first work is extremely shortsighted and poor quality.

One could put something cool together without internet using Delphi. The Borland IDEs were ahead of their time - built-in debugger, profiler, and pretty good documentation. My 'internet' was the SWAG Pascal snippet collection (which could be used fully offline). Someone converted it to HTML:

You make a solid case for abandoning the web. To be clear, in my mind I separate “the web” from “the net”; the web exists on top of the ‘net!

The web has become a cesspool of AI slop, SEO trash, walled gardens, and of course, bots of all kinds seeking entry points to everything. The dead internet theory seems more real every day.

I think humanity will ultimately abandon the web. The day cannot come soon enough for me.

> When people discuss Japan being a homogeneous society, that typically refers to it being a very ethnically uniform society.

Even if you ignore tourists that's not really true of Tokyo either. Japan doesn't collect ethnicity statistics though - the numbers for this you may have seen are misreadings of something else.

> Surely you're not trying to claim that what people actually mean typically is that Japan is homogeneous in every arbitrary way possible, right?

That's absolutely what people online think about Japan, they think it's a stuffy collectivist society where everyone agrees with each other and there are no immigrants.

Improved comparison sort when?

The following algebraic point of view could be utter hogwash, so I might embarrass myself... but if you think about it, the "merge" operation is isomorphic to the product in a free commutative monoid (over a large number of generators, otherwise you can use Counting Sort). So sorting is all about computing a bunch of products (merges) in the optimal order. Now consider mergesort, insertion sort, Timsort.

Well, there's another aspect which is that the original authors and pop-sci journalists don't seem to be able to understand where they went wrong or how outrageous their claims are, precisely because their jobs depend on not understanding. The could have corrected it. We could not still be circling this drain 2 years later, but we are.

Kinda classic. Kinda boring.

The idea of AITAH reflecting "real life morality" is interesting, but indeed would only remain interesting for such a question when it also addresses LLM training and bot posts+comments, as well ad human fakes/ karma farming / spam.

Perceived morality is still interesting when it comes to the content, but ignoring this "dead internet" aspect is a glaring omission.

This subreddit and similar ones sometimes almost feel like ChatGPT "ground zero" to me, regarding the fine-tuning towards a chatbot for humans, and RLHF (vote system...)

By now it has become a feedback loop, I'd assume, and Reddit collaborates with AI companies, so maybe they even can separate extremely easily between obvious bots or manipulation and human posts. Also, they can already do that 90% on their own, given the platform design. E.g. detecting an essay pasted into an editor, IP ranges, etc pp.

There has been content and subs popping up in other languages that feels similar, for quite a while.

From hyperlocal (city) subs to topic subreddits, manipulation and LLM content is everywhere.

What most people refer to as "culture" or "art" are products that are vectors for identity in a fractured society. If the author feels malaise over not being able to find to find new things to watch and listen to, imagine how hard it must be to just be yourself these days and foster communities around the likes and dislikes that you share with other people. Curating/taste-making is identity politics.
by js8 | 2025-05-17 18:35:23+00:00
It's not the same argument because I don't make any assumptions about how LLMs work. All I am saying that people have been able to keep reality in check in the presence of cultural artifacts, and will continue to do so even if such artifacts are produced by AI. Because what makes these artifacts interesting to humans is their relation to the (truth of the) real world, and that's regardless of who or what produces them.

I think part of the answer is that not everyone is convinced it's pivotal.

Only a small amount of aviation is pivotal by any definition, and that portion isn't very price sensitive, so paying for externalities wouldn't make much difference to it.

Even in the richest country in the world, only half of the population took even one plane trip in 2024, and the distribution among those who did, probably skews heavily toward a very small # of frequent fliers.

Aviation is super useful, no doubt. But like many difficult political problems, the benefits are concentrated on those who fly the most, or who consume most of the products that typically fly, and the costs are spread among those who fly the least, or not at all.

Anyway, I have never seen someone advocate to ignore coal in favour of focussing on aviation. But I have seen a lot of people advocate to ignore aviation in favour of focussing on anything but aviation.

As others have said, we can do more than one thing. Some of us can focus on coal, others on aviation. I am just a message board pundit, not involved in coal or aviation, nor advocacy around climate change on either. I am just skeptical of approaches that privilege one pollution source over another. Maybe politics means it's the best we can do, but that's not a very satisfying answer to some of us.

> But that's not what MCP does. It is a tool created by anthropic ( 2nd most used LLM) to provide portabiliry and vendor neutrality between different LLMs. It's like terraform for LLMs.

Given that your only contributions in this thread are to acknowledge your ignorance of MCP [0] and to post the summary dismissal upthread that shows your ignorance of it, it would probably behoove you to actually learn about MCP more before confidently making assertions about it. Suffice it to say that this is inaccurate and others have already explained in your "WTF is it" thread what MCP actually is.

> Also providing data through function calls/tool use is not context, you are overloading the term. Context is LLM context, if you fetch from a db it's something else

If you believe this then you don't understand how tool use is implemented. It's literally accomplished by injecting a tool's response into the context [1].

As a general life tip: most pedants are wrong most of the time. If you find yourself being pedantic, take a few steps back and double check that you're not just wrong.

> It would also mean that quantum field theory in curved spacetime can only be consistent if baryon number fails to be conserved! This would be utterly shocking.

Is it really shocking (today)? I mean, isn't this a logical consequence of Hawking radiation for black holes? I thought we were shocked by this a long time ago, but now we're ok with it. The authors of the paper in question may very well be wrong in their calculations (I can't say), but this blog post doesn't smell good to me because of doubtful statements like these, passed off as so obviously true that you must be an idiot not to agree. That kind of emotional writing does not become someone whose profession should focus on scientific persuasion.

From Wikipedia [0], itself citing Daniel Harlow, a quantum gravity physicist at MIT:

> The conservation of baryon number is not consistent with the physics of black hole evaporation via Hawking radiation.
