As someone else pointed out, the short story is cost. Mines are cheap, make them more advanced and they are not cheap.

That said, even if the trigger is disabled, it's still an explosive device and should still be cleared (or never placed in the first place, as the Ottawa treaty says which the US, China, Russia, India and Pakistan are not a part of https://en.wikipedia.org/wiki/Ottawa_Treaty)

If you thought the Butlerian Jihad was silly, you may have missed a few important nuances in Dune. I mean I suspect the concept was originally a convenient way to explain why tech in Dune hadn't advanced all that much in 20k years, but the in-universe explanations are pretty good.

In fact they are somewhat similar to the reasons why the Melnibonéan empire fell in the Michael Moorcock Elric universe: people got lazy, spent their time drugged out of their minds, and cruelty seemed to be one of the few things to get a rise out of them. In Dune labour was delegated to (thinking) machines, in Elric it was delegated to slaves. Eventually such a society will collapse or be conquered.

It's more likely for them to accidentally be deleted (or otherwise lost access): in my experience approximately zero users actually understand where their passkeys are stored, and they can be all over the place: the number one question I get is 'why can't I log in?' because they've accepted a passkey setup dialog on one machine without really reading it and now can't log in on another. Sometimes it's on the same machine but in different contexts. No passkeys should be considered something that the average user is going to reliably hold onto.

>You need to look closer at how the government is trying to use the 'supply chain risk' designation. Hegseth said this:

>> Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic.

If Anthropic is really serious about their moral stances they could themselves refuse to sell indirectly to us military. Militarirs are ultimately about killing people. So yes, if the supply chain risk is that anthropic might suddenly pull out of military projects and leave people depending on them high and dry, this seems like an appropriate response.

> Most things can't be taught to do arithmetic, making this "transformer" thing slightly magical.

Yep, for people who don't have know the fundamentals (i.e. maths). To people who don't know the universal approximation theorem, this may seem like "magic", but it's just as much magic as making a dark room bright by flipping a light switch.

I’m a Brit, married to an Iranian who still has a large family in Iran. I’ve got to witness first hand quite the opposite to what you describe, at least with the British mainstream media. With the exception of one religious aunt who is married to a military man, OP’s comment reflects the feeling of all the Iranian family and friends we know. And FWIW, I can point to Iran on a map, and I am not Mossad.

> They sit on disk as plaintext, readable by any process running as your user

The proposed solution:

> Instead of loading secrets from a file, you use a wrapper script that fetches secrets from a secure store and injects them as environment variables into your process

Now they sit "on disk" as plaintext, in /proc/self/environ, still readable to any process running as your user.

Well, you say this is not a topic for this site, but HN is explicitly about intellectual curiosity and as long as you present your case with enough complexity and new information, any topic should go. It's not the topic, it's the way you go about it.

You raise an economic, political and maybe societal, ehr, question? It is not entirely clear to me what your inquiry or proposal is. You can help the community accepting your topic by being more clear and information rich.

The crisis in the Middle East is a terrible thing, but I don't think it will lead to a majority of people being "screwed".

The money printing is not really a danger in that sense. Yes, I also do think we should manage to have a better banking and currency system, FIAT is less than optimal, but it's not the case that it doesn't work at all either.

I don't know who you are referring to with "normal people", but I am inclined to not see the HN crowd as normal people. Depends on your parameters of course.

Author here. I shared the GitHub repo a few days ago (https://news.ycombinator.com/item?id=47148025) and got great feedback. This is the writeup explaining the architecture.

The core idea: every MCP tool call dumps raw data into your 200K context window. Context Mode spawns isolated subprocesses — only stdout enters context. No LLM calls, purely algorithmic: SQLite FTS5 with BM25 ranking and Porter stemming.

Since the last post we've seen 228 stars and some real-world usage data. The biggest surprise was how much subagent routing matters — auto-upgrading Bash subagents to general-purpose so they can use batch_execute instead of flooding context with raw output.

Happy to answer any architecture questions.

Many do what you describe, probably because some manager somewhere needs to tick some checkbox.

But GitHub, specifically, allows you to sign in with a passkey. On the sign-in page, there's a "sign in with passkey" link. It activates my 1Password extension, asking if I want to use my passkey. I say yes, and I'm in, I don't type anything. This also works the same way with my YubiKey.

And unlike Uber and Airbnb, OpenAI has no way to maintain marketshare. It’s a domain name with no moat.

Google has to pay Apple billions of dollars to make Google.com the default search engine. I just looked it up, over 15% of search revenue goes to pay to be the default search engine.

Every Android device defaults to Gemini.

Every Microsoft device defaults to Copilot.

I’d love to see where these cost reductions are. If costs are going to decrease rapidly why does OpenAI’s spending plan look so insane?

Over the last 48 hours we shipped a major update to our open-source observability + infra + AI runtime stack.

Big changes:

Renamed kakveda-aankh → kakveda-netra

Built as a real host-level agent (CLI + systemd support)

Background mode (--start, --stop, --bg-status)

Full infra metrics:

CPU, memory, disk, network, load

Docker container metrics

temperature, FD usage, diagnostics

Kubernetes inventory:

nodes, pods, deployments, services, configmaps, secrets

kubeconfig auto-detection

Dashboard upgrades:

golden signals

trend charts

thresholds + alert coloring

detailed drilldowns

Custom dashboards:

saved layouts

YAML import/export

Runtime control of host agent from dashboard

Cost comparison docs (Datadog, AppDynamics, Logz.io, LangSmith etc.)

The idea is simple:
Infra monitoring + AI/agent governance + observability in one platform.

Still early. Would love feedback from infra engineers and K8s folks.

This isn't a footgun, you just have absurd security requirements.

>It should be pretty obvious that using a passkey, which lives in the same password manager as your main sign-in password/passkey is not two factors. Setting it up like this would be pointless.

You simply do not need two factors with passkeys. Using passkeys is not pointless, they are vastly more secure than most combined password+2fa solutions.

There are extremely few contexts where an yubikey would be meaningfully safer than the secure element in your macbook.
Might Be the Most Underrated Resource for Early Stage Founders
by vibecoder21 | 2026-02-28 10:04:01+00:00
Early stage founders don’t usually fail from lack of ambition, they fail from lack of clarity. The hardest part isn’t building, it’s deciding what deserves to be built. Most people bounce between Reddit threads, X debates, random newsletters, and half-baked trend reports trying to find direction.

But every now and then you stumble on a resource that quietly removes that chaos. Something structured. Something searchable. Something built around actual problems instead of hype cycles. I’ve noticed more founders referencing StartupIdeasDB on Google lately, not as a shortcut, but as a thinking tool.

It helps you see patterns across industries, validate whether a pain point keeps resurfacing, and understand why certain ideas make sense in this moment. That shift from “inspiration” to “organized signal” is powerful.

When you stop guessing and start analyzing, your confidence changes. And for early-stage builders, confidence in direction is half the battle.

My point being that no one should be buying expensive GPUs when you can pick up a few used ones to get started. But for the sake of discussion let's say you do get a blackwell pro 6000 that's now going for $10,000. I can assure you it will not be $150 10 years from now, with the falling price of dollar, demand for AI inference and hardware shortage, it might cost exactly the same 10 years from now...

I think you're missing the point: a constant justification for bombing Iran is that they are one month, one week, or a couple months from building a nuclear bomb.

If that was true, obviously they would have built one buy now. Being one year away from building would be non-urgency inducing.

The constant lying about timelines does not imply Iran does not enrich uranium, but, as you remember, after the last bombing the leaders of the USA and Israel said they had completely obliterated Iran's nuclear program. Except, apparently After six months they are one week away from a nuke again.

This seems to indicate the USA should be bombing Iran every few weeks, forever, just in case they get a bit faster next time.

Except, when we don't have any scandal or other crisis going on, then Iran does not seem to be getting a nuke quickly. I wonder why.

Passkeys on iOS and macOS actually work quite well in that regard. They get stored in your provider of choice across the web, web views, apps etc., at least in my experience.

Mine is Bitwarden, and that's available on pretty much all platforms, natively where available (except on macOS currently), as a browser extension otherwise.

For the rare instance in which I need to authenticate using a passkey on a computer where I'm not logged into Bitwarden, there's the cross-device CaBLE flow where I can scan a QR code with my phone and use Bitwarden to authenticate. This works across OSes and browsers.

Starred.

I am looking to that exact concept - for a different mean - to develop my agent orchestration hobby project.

LLM working in a «feature folder» where it stores change-logs, documentation, summaries, requirements, attachments, and so on. What I will be looking into very soon, is also storing the session id, for summarisation, history context, and so on.

I will definitely steal some concept from your project.

Assuming models of a fixed size continue to improve in capability, continued advancement in semiconductors and optimization will reduce power consumption and/or improve performance over time. And used equipment will always approach the scrap price eventually. For me today, on scrap equipment, I get about 4 tokens / watt-hour, which is nominally ~$0.17 US but could run $0.40 after all the taxes and fees and surcharges. $0.10 / token. Ouch.

If I were to try to purpose build a rig for it, I would get an engineering sample Epyc/motherboard/ram combo from Aliexpress with 12 channels of DDR5 and as few cores as allowed me to still use all the memory bandwidth, and I'd run it at the lowest possible power and voltage settings with aggressive ram timings. A system like that can draw 1/3 of what my scrap rig draws, at full load. And has similar memory bandwidth to a high end Mac or GPU allowing it to crank out 5 - 10 Tokens / s on the largest models, which works out to 1/3 of a penny to 2/3 of a penny per token. But either way, Epyc or Mac is going to set you back $10k or more. Hopefully in a few years when they are scrap though...

Some vendors will decide to sue the government. Others may decide that switching to another LLM supplier is cheaper and lower risk.

And I'm not sure your confidence in how the courts will rule is justified. Learning Resources Inc v Trump (the IEEPA tariffs case) proves the SCOTUS conservatives – or at least a large enough subset of them to join with the liberals to produce a majority – are willing sometimes to push back on Trump. Yet there are plenty of other cases in which they've let him have his way. Are you sure you know how they'll judge this case?

The place has 90 million people, how do you even deal with this without throwing the whole place into chaos?

Besides, after this the collective west has no moral high-ground anymore, the global south will resent us more than ever. If other countries go to aggressive wars, our condemnation is worthless.

Trump is completely compromised and it was probably the powers that be who told them that this is how it is going to be.
by rzzzwilson | 2026-02-28 10:07:19+00:00
It's a start, for sure, but not even Trump knows how it will end. He has opened Pandora's box[0]. I'm reminded of a quote from Churchill:

Never, never, never believe any war will be smooth and easy, or that anyone who embarks on the strange voyage can measure the tides and hurricanes he will encounter. The statesman who yields to war fever must realise that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events. Antiquated War Offices, weak, incompetent, or arrogant Commanders, untrustworthy allies, hostile neutrals, malignant Fortune, ugly surprises, awful miscalculations — all take their seats at the Council Board on the morrow of a declaration of war. Always remember, however sure you are that you could easily win, that there would not be a war if the other man did not think he also had a chance.

I just made a project, added all my exams (they were piling up, me and my psychiatrist had been investigating for a year this to no avail) and started talking to it about my symptoms.

Within a few iterations of this it gave me a simple blood panel, then I did that one and it kept suggesting more simple lab or at home tests and we kept going through them until I was reasonably certain of “something” and now that I have hypothesis I am going to a doctor. I think it’s done a great job. I also kept asking it for simple lifestyle interventions to prevent progression of my issue and it consistent nailed it - one particular interverntion (adding salt to water and drinking it to prevent symptoms) made a huge improvement to my life - I was barely working before that.

I added in some text the instructions box (project master prompt) for it to realise - it’s not medical advice and I am aware of that (prevents excessive guardrails) - add confidence intervals and probability to all diagnostic statements (prevents me + Claude going into rabbit holes so easily, it often has 70-80% certainty of what it’s saying, but it’s clear that it doesn’t use the right language) - that It was talking to an non expert, to use simple language but to go into detail when necessary. I also ask it to stop doing unnecessary constant follow up questions to every answer as that causes me anxiety. I can share the prompt, in fact I might do so later as it might be useful to others.

Americans voted for no new wars, and especially no new wars in the sandbox, and they got a new war in the sandbox.

Americans really have to be among the most gullible people on the planet.

Not to mention that Trump is a paedophile, the open corruption, attempted coup etc... it's like that Hemingway quote. The decline of the USA has been gradual, and then very sudden.

It is absolutely unfair to say it. Just like passwords stored in a password manager, passkeys can be copied out of the device for safekeeping. Because you can copy them out, a user can be induced to give them to someone.

I saw passkey boosters go very, very rapidly from "Passkeys are immune to phishing!" to "Passkeys are phishing resistant!" when lots of real-world people started using passkeys and demonstrated that you absolutely must have a way to back them up and move them around.

Are you using this code for Julia?

https://github.com/JuliaParallel/rodinia/tree/master/julia_m...

It was touched 9 years ago, but maybe you have ported it to current standards. I don't think we had multithreading at that time, only multiprocessing.

Is your Julia implementations available somewhere? (Sorry if it is in your paper but I missed it).
I vaguely remembered in the past that working with threads leaded to some additional allocations (compared to the serial code). Maybe this is also biting us here?
by lxgr | 2026-02-28 10:11:35+00:00
Sure, but then you still need a protocol between user agent and website. If you just do this in Javascript, you're not protected against phishing sites just forwarding the password entered directly.

Passkeys can in fact be backed by exactly this, i.e. a HMAC-only stateless implementation backed by a single password: https://github.com/lxgr/brainchain

You can't copy them out on at least the iOS, Android, and (to my knowledge) Windows default implementations.

Millions of people use them without being able to move them around in the way you describe.

Anthropic doesn't object to fully autonomous AI use by the military in principle. What they're saying is that their current models are not fit for that purpose.

That's not the same thing as delivering a weapon that has a certain capability but then put policy restrictions on its use, which is what your comparison suggests.

The key question here is who gets to decide whether or not a particular version of a model is safe enough for use in fully autonomous weapons. Anthropic wants a veto on this and the government doesn't want to grant them that veto.

Yes, yes, yes. When I first read the stuff about this yesterday, my immediate thought was "wait, these are the only two things they have a problem with?"

But they made a stand, and that still matters. We shouldn't let the perfect be the enemy of the good. At least it's not Grok.

Only for dc/marvel-shaped brains where there are evil guys who do bad things, and they're opposed by good guys who spread goodness.

> to ethnically cleanse the indigenous population from their ancestral land

Like after creation of Israel, Arabs motivated (often violently) Jews to leave their homelands and move to safe Israel, thus proving zionist ideas to be right. And then wonder what people support these zionist ideas now? Any ideas? :-)

Apparently you don't even have to give Americans the neocon foreign policy spin anymore, we generate it ourselves.

To wit, after Maduro was kidnapped and the exact same regime kept in place (minus selling oil to Cuba), and Trump openly said it was to control the oil, most of the reactions were pretending we live in a universe where the US does these things to spread democracy.

the problem so far is UI and incompatibility across devices, OSes etc.
I am a big fan of Passkeys and the idea of using PRF for E2E encryption, but I wouldn't implement that as now, there is almost zero control over where those passkeys are, how I can recover them, how I manage them. Whenever I have to switch computer (mandatory policy at work), or phone (mandatory obsolence) or if I want to work across OSes (Mac for work, Windows for fun), everything falls apart, incomprehensible interfaces, inexistent transparency and control. And I'm a pro user that has actually studied how the standard works.

I'm afraid that it'll take some few more decades before we will get rid of passwords, if ever.

I really like your answer in soo many ways because i can see that it made you think in really possitive way. For something like this i really can not say i can be more information rich as this is soo deeper than informations we have, unfortunately... Its much easier to talk about some science or tehnology where we can read documentation and really understand it .
Just to answer this moment "screwed". Its not about money i lived through hard times like most of us lived and we will keep living but i think making world thinking this is normal will put us in really bad moral. World is going in direction that everything is okay if you are making money out of it, and thats completly wrong.
On your statment about FIAT , i agree. Its not that bad thats truee but somehow same opportunity should be given to everyone. Not in termes of luxury but in terms of basic rights its completly wrong if people are doing same but one is living normal and other is struggling to survive. In my opinion every country is rich as rich as its poorest inhabitant... I dont know man this is such a hard topic to talk about and we could talk all day...

Exactly this! Just like the Gulf of Mexico is still called the Gulf of Mexico, if we just ignore his ramblings and continue calling the department of defense, we undermine his whole point. If we fall for all their crap and just accept it, then we loose in the end. Any resistance to a Fascist government is good resistance. Anything that makes their life's a little shittier is good. Better that they go around having tantrums about how they renamed it but no one is paying attention.

> in my experience approximately zero users actually understand where their passkeys are stored

Passkeys are designed to be hidden from the user. The author of this article even went on GitHub telling an open source implantation to not let users copy the private key.

https://github.com/keepassxreboot/keepassxc/issues/10407

There is a good reason for it. If you can copy and paste your passkey, then a phishing site can just ask you for it, making the phishing protection passkeys provide moot.

But the consequence is people, including many technical users on this website, cannot get a grasp on passkeys both as a concept and in a literal sense. How can you perceive, let alone understand, something that is designed to be hidden from you? It also doesn't help that it was pushed on users with little explanation and comes with many seemingly incompatible implementations.

Unless passkeys are redesigned to solve the intangibility problem, grannies will keep losing their accounts for no good reason and we will keep arguing about it on HN.
