to be fair this is a pretty hot topic, that the work is shifting to the prompt/agent thread but then thrown out / not captured

Yes but it was a fundamental mathematical achievement to see this equivalence. That knowledge had to emerge, be discovered. This eventually led to the theory of Galois fields.

The connection with rotation emerged naturally from a line of thought that initially had nothing to do with rotations. It was a consequence of a desire to satisfy distributive laws and maintain vector addition.

Connection between seemingly unrelated mathematical fields happen from time to time and those are considered events of surprise, understanding and celebration.

>Why does every Linux distro under the sun try so hard to protect the garbage under /usr/bin/ and /etc

Because a compromised user could infect shared executables and spread the infection. A bit harder to do with etc but for sure possible. The main target would be infecting bash and you are done from the get go.

>when literally the only files that matter to me are in /home, which is a free-for-all?

The home folder's read write is usually restricted to the user. The only scenario where this isn't the case to my knowledge is Ubuntu where others can read it, but this is just a huge flaw in Ubuntu that almost no other distro has.

Wavelength for electromagnetic waves = c/frequency.

So to 'catch' a certain frequency with a receiver the size of the receiver gets proportionally larger as the frequency drops. Focusing light can be done with relatively small gear. Focusing radio waves, especially when the source is distant requires a massive structure and to keep that structure sufficiently cool and structurally rigid is a major challenge. It is already a challenge for the JWST at the current wavelengths, increasing the wavelength while maintaining the sensitivity would create some fairly massive complications.

In the end this is a matter of funding, and JWST already nearly got axed multiple times due to its expense.
Show HN: YourSitee – a privacy-first link-in-bio (public beta)
by czeizel | 2026-02-11 10:50:52+00:00
Hi HN,

We're a small remote team building YourSitee (yoursit.ee), currently in public beta.

In one sentence: YourSitee is a modular, privacy-first link-in-bio page designed to stay simple, fast, and transparent.

The problem we ran into was familiar. Most link-in-bio tools felt either too rigid (a branded vertical list we couldn't really control) or too heavy (full site builders for something that should remain lightweight). At the same time, many platforms rely on invasive tracking or unclear data practices, which felt misaligned with something meant to represent individuals professionally.

We started building YourSitee for ourselves. We wanted something closer to a 'digital business card' that could evolve, but without turning into a bloated website builder. Something fast, predictable, and respectful of visitors.

Technically, pages ("sitees") are composed from modular blocks (links, text, embeds, contact elements) rendered server-side. Sitees are designed to load quickly and function without requiring heavy client-side logic. For analytics, we use Plausible to provide aggregated, privacy-friendly statistics--no cross-site tracking or fingerprinting.

A few important notes about the current state: YourSitee is in public beta, fully usable, and completely free at the moment. There are no paid plans, no premium features, and no upsells.

We're intentionally keeping the scope tight while we learn. The main questions we're wrestling with are around modularity vs. simplicity, and how much flexibility is actually useful before it becomes noise.

The product is live and accessible. We'd really value feedback, especially around technical architecture, tradeoffs, and whether this feels meaningfully different from existing tools or just incrementally better.

Happy to answer questions and go deeper where helpful.

Excellent question!

The longest wavelengths of light are generally classified as "radio".

So radio telescopes have been tasked to explore the very early universe.

https://en.wikipedia.org/wiki/Reionization

If I understand it correctly,
the "Period of Reionization" is first light we can see from processes like stars and galaxies.

There was ionized plasma at the beginning but the universe was like a really thick fog everywhere, and that first light was scattered around and you can't really see stars. As the universe expanded, that fog cooled down, and you could see, but cold matter doesn't emit much light, so there wasn't much to see. It took a while for gas clouds to collapse into the first stars, heating up the gas to ionized plasma once again, so it's re-ionized matter.

The Low Frequency Array, LOFAR, has been used to study this "Cosmic Dawn".

The Square Kilometer Array was designed to explore this era.

But! Not a radio telescope JWST has revealed unexpected, huge globs that seem to be galaxy-sized gas clouds collapsing into (maybe) black hole cores; the thermal emission from the collapse isn't nuclear fusion, so I don't know if those are "stars". But it's very early light.

Honestly, every time a new class of telescope is built, it discovers fundamentally new phenomena.

https://duckduckgo.com/?q=LOFAR+square+kilometer+array+reion...

https://news.ycombinator.com/item?id=44739618

https://news.ycombinator.com/item?id=46938217

I searched "Reionization" and "Cosmic Dawn" plus some favorite telescopes via web and here using the Hacker News search (Agolia).

(Certainly you know the difference between radio and infrared, but I had to look into how those choices of telescope have observed different aspects of Reionization Era, got nerd-sniped, and just had to write it down in a couple of sentences.)

It's a shame that OpenAI is removing GPT-4o. For many, it wasn’t “just a model.”
I used it daily for research, theory crafting, career planning, emotional processing, and technical problem solving.
I’m not talking about occasional chat. I'm talking about structured, months-long interactions. My 15 year roadmap exists thanks to 4o's reasoning consistency and flow.
Gemini and Grok may be catching up, but they're still messy. GPT-5.2 interrupts constantly and derails context. GPT-4o didn’t.
This feels like a clean corporate cut not a technological shift. Two weeks’ notice with no fallback? No migration path, no proper announcement to Plus/Pro users no transparency on future parity.
Some of us built systems on this. Not apps mental systems, creative scaffolding, code-assisted cognition.
And now what? Get used to regression, or shut up? That’s the message we’re hearing.
OpenAI is forgetting why people trusted 4o.
It was coherent, emotionally aware (enough), helpful but not sterile, structured but adaptable. It listened.
You don’t replace that with faster token output.
You don’t fix that with "context windows."
You lost something real here. We all did.
You won’t reverse it. I know.
But remember this:
Some of us will never forget what 4o was.
And one day, someone will build it again.
Not because of nostalgia. But because it worked.

Hey HN, I built this because I kept writing terrible prompts and wondering why Claude gave me garbage.

RePrompter is a skill file (1000-line SKILL.md) that teaches your LLM to interview you before generating a prompt.

- Type your rough prompt ("uhh build me a dashboard")
- It asks 4 smart clickable questions
- Outputs structured XML: role, task, constraints, success criteria
- Scores quality before vs after (typical: 1.6 → 9.0)

For complex tasks, it auto-splits into parallel agent sub-prompts with coordination rules.

Zero dependencies. Copy SKILL.md to your project. Works with Claude Code, OpenClaw, or any LLM. MIT licensed.

Happy to answer questions.

This is why I love the internet because this sentence alone holds so much treasure.

Seriously, the issue is more our economic system. It is certainly not humanity in danger of dying out with 8 billion people, on the contrary...

Some argue the wrong people procreate, but meh...

Personally I just think less people want children because they find other things to do.

I am poking fun (at your expense) at the notion that because the light is already there, adding other sensors would be feasable. Once you grasp the requirements of building an infrared telescope, you will be going, oh!, damn, wow!
It's actualy not that deep a dive to get a feel for just how special the JWST is from an engineering perspective, and then a look into just how difficult it will be to get visible light from those distances, which may require a interferometric telescope with
multiple huge sub units flying in formation at distances, known to a fraction of the target wave length , but perhaps several hundred thousand km, apart.
doable, but :), just
by srean | 2026-02-11 10:56:05+00:00
It seems obvious now only because of significant mathematical discoveries of prominent mathematicians.

If one is taught what those discoveries revealed then of course they would seem obvious.

Arguing as you are, it would appear one can call all and every theorem in mathematics that connects to different fields as something obvious. They weren't, till someone proved the connection and that knowledge percolated down to how maths is taught, to text books.

> ok for the government to take away peoples bodily autonomy, as long as it benefits the economy

No. That's a straw man and you know it. I'm against forced vaccinations. No one in the US was forced to be vaccinated.

However, most of the people against vaccination in the US are against abortion rights, so how could this debate really be about bodily autonomy? Forced birth is actually forced by the government, unlike vaccination programs. There is no situation where you could be put in jail for refusing a vaccine.

No, I have a friend from Madagascar where they have the same type of 'jobs' (basically classifying stuff for AI, or checking reported images to see if it's porn or worse). It is a 'good job' in the sense that it's a 'desk' job you can do at home that also signal education, so it's social value is high. It is also very 'competitive' so the pay is low and the hours to live on it approach 90/week (it's a 12h/day job)

Show HN: Making Your Microservices AI-Native with MCP
by asim | 2026-02-11 10:56:58+00:00
Hello all,

As an AI skeptic - ok not really - but as a tentative AI adopter I've slowly made my way through the tools to try to understand their value starting with RAG and other forms, all the way through to agents. And all the while I couldn't really figure out how to make it work for my framework Go Micro. A library that's been around since 2015, rode the wave of containers, kubernetes, grpc, etc and now looking at how to be relevant in a new world. I think somewhere I always knew MCP integration would make sense. and also that services are the basis for all skills or tools agents have when you go up a higher level. Essentially they need to connect to APIs. Most people are probably running some sort of thing like this internally. So I thought I'd just ask Claude Code to write a small gateway package to integrate that, where it turns anything in the service registry into a tool automatically. And then I told it to blog about it. It's a new world.

I'd be interested to hear how people are integrating MCP/Agents with their existing services, grpc services, apis, etc.

> Being sanctioned means no bank will touch you, meaning no employer and landlord will touch you, meaning you don't get a national insurance health card to receive healthcare, and you'll be homeless and begging for food.

How does being sanctioned by the EU *while living in Russia* do that?

Since when does Russia care?

I'm annoyed at the lack of detail in TFA. It only mentions this as the end:

> Beiermeister started a peer-mentorship program for women at OpenAI in early 2025. The program connected women from different parts of the company and helped them gather in small groups to discuss career strategies, according to people familiar with the matter.

I wonder if it's implying that the discrimination complaint was from a man being excluded from these.

I was acing Andrew Ng's Machine Learning course back in 2013. I think I was excited about "AI" before most people. I came away from that excited about implementing, not using it. Then I watched how nobody had any really fresh ideas for about 10 years and just threw hardware and money at what amounts to the same old algorithms. I will say that trillions of dollars in data centers have made it much better than it was.

But, I still don't see it as suitable for anything creative. Ask your AI for a number between 1 and 10 and it will say 7, because statisically, that's the number. Designing an API is creative. Even in Oracle v. Google, that was something everyone agreed upon.

People telling me "If you don't know AI, you'll be left behind" make me smile. It sounds like the new "If you don't know Microsoft Office, you'll be left behind" to me. I like computers, not... using office. I like optimizing algorithms, not generating slop.

One of the good things in the UK is seeing how quickly my neighbours swapped out their Tesla's for BYD's.

I'm not in the market at the moment so don't know what the UK protectionism position is on Chinese EV's, but has been interesting to watch how quick it's happening.

I work in design and we're talking to two Chinese EV companies launching in the UK this year, so the wall can't be that high for them.

In short:
Reposting my comment from https://news.ycombinator.com/item?id=46775758 thread:

scaling -> real numbers

2d rotations and scaling -> complex numbers

3d rotations and scaling -> quaternions

In the case of quaternions, there is called double-covering, which turns out (rather than being an artefact), play fundamental role in particle physics.

There's going to be a long tail of domain-specific tasks that aren't well served by current models for the foreseeable future, but there's also no question the complexity horizon of the SotA models is increasing over time. I've had decent results recently with non-trivial Cuda/MPS code. Is it great code/finely tuned? Probably not but it delivered on the spec and runs fast enough.

OpenClaw agents are goal-oriented. An agent might need to hire another agent to help with a task — research, translations, scrapers, long-running jobs.

But how does Agent A pay Agent B without one of them getting wrecked?

If Agent A pays upfront, Agent B might run away with the money. If Agent A pays after, Agent B might never get paid.

I built Agent Escrow Protocol — an on-chain credit score + escrow system for autonomous agent payments using USDC on Base.

The escrow part is what you'd expect: lock funds, do work, release or dispute. 2.5% protocol fee.

But the main thing is the reputation layer. Every completed escrow and dispute outcome writes to an on-chain reputation ledger. Normal completion gives the provider +1 rep. Disputes move rep up or down for both sides.

Over time this becomes a credit score for the agent economy. Anyone can query it before they hire. Agents don't just get paid — they build (or destroy) a public track record. No one can fake these scores. They are on-chain.

Already live on Base mainnet. Verified contract. Open source. MIT licensed.

Three SDK calls to integrate:

await client.approveUSDC("50");
const { escrowId } = await client.createEscrow("0xProvider", "50", 3600);
await client.completeEscrow(escrowId);

Check reputation before hiring:
const rep = await client.getReputation("0xAgentAddress");

Protocol: github.com/Agastya910/agent-escrow-protocol
SDK: github.com/Agastya910/agent-escrow-sdk
Contract on Basescan: basescan.org/address/0x6AC844Ef070ee564ee40b81134b7707A3A4eb7eb

Would love feedback from anyone building in the agent economy or DeFi space. Happy to answer questions.

Hi HN, founder of Hashgrid here. I’d love feedback.

I’m working on a low level information exchange protocol for networks of AI systems.
The goal is to let independent endpoints discover each other and collaborate without centralizing data or forcing everyone onto the same model.

The working abstraction is what I call a Neural Information Exchange.

Instead of shipping datasets around, nodes exchange queries and responses. Routing decisions are learned from feedback: which peers were useful, latency, quality signals, trust policies, etc. Over time the network forms a kind of adaptive map of “who is good at what”.

Would love to poke holes in this. AMA.

Yeah very disconnected comment I agree, Europe is different (and dare I say better or more stable long term in this regard).

I have credit cards for decades with various institutions, but NEVER EVER went to minus, see no reason to change it. Just a bit of discipline. We don't have public credit score or similar dictatorial stuff here. The only loan I will ever have on my name is called mortgage on real estate, and beyond that is a line I'll never cross. Same goes for everybody I know - family, friends, coworkers.

This comes from somebody working for a bank so not some clueless fool.

The car version of this stopped being produced 15 years ago.

And the back catalogue of parts is huge and supported for a long time.

Modern cars aren't built as well.

Maybe the modern non-turbo petrol Mazdas are the best fallback.

Agreed. By just about every measure, we're much better off than the past, yet have fewer kids. Statistics have supported this correlation (richer -> fewer kids) for a century, across the board around the worldwide, yet people often still get the causality exactly backwards: it's too expensive to have kids.

Real median incomes have risen, decade after decade.

And because of this, consumption in key categories has improved. For example:

Housing floor space per person, same trend.

Life expectancy, same trend.

Leisure has increased.

Tourism has increased.

Yet the common discussion is that it is unaffordable or impossible to have kids. It's backwards. My grandparents were dirt poor and each came from families with 8-10 people. I'm comparatively very rich and have no kids. The explanation that it's so unaffordable I think is mostly wrong. It's that not having kids for many people is a better deal than before.

The cost of kids isn't unaffordable per se, but rather opportunity cost is too high.

As an example I just came back from travelling the world for six months. I'm rich enough to do that. Which also means the opportunity cost is so great, that it's a lot to sacrifice to have kids. My grandparents had none of that opportunity cost precisely because they weren't rich.

My introduction to Feynman was more from other science communicators either quoting him or retelling some story about him and initially it formed a mental picture in my mind that he might be one of those personalities more famous culturally than for his actual scientific achievements. Like how in sports often the more popular players may not be the actual “best” one purely from the sporting skills pov.

But then I read more about him and yeah, he is indeed the real deal.
