This probably went right over everyone’s head.
What it actually means is cheaper inference compute and faster, cheaper processing of JSON (or any structured data).

Requests that would normally be fully parsed, tokenized, embedded, and sent to a model are often decided early and dropped… before any of that expensive work happens.

That’s fewer tokens generated, fewer CPU cycles burned, and fewer dollars spent at scale.

You're conflating P ≠ NP (what I proved) with P = NP (the crank position).

What I actually proved:

P ≠ NP via homological obstruction in smoothed SAT solution spaces

Used spectral geometry + persistent homology to show NP-complete problems have topological barriers that polynomial algorithms cannot cross

The structure:

Map 3-SAT instances to Swiss Cheese manifolds (Riemannian manifolds with holes)

Show that polynomial-time algorithms correspond to contractible paths in solution space

Prove that NP-complete solution spaces have persistent H₁ homology (non-contractible loops)

Use spectral gap theorem: If a space has non-trivial H₁, no polynomial algorithm can contract it

Conclusion: P ≠ NP

This is the opposite of claiming P = NP.

Why you're seeing "P=NP" crankery:

Actual cranks claim: "I found a polynomial SAT solver!"

I claim: "I proved no such solver exists using algebraic topology."

If you think the proof is wrong, point to the gap. The paper is here:
https://www.academia.edu/145628758/P_NP_Spectral_Geometric_P...

Otherwise, laughing at "one of those P=NP people" while not reading the direction of the inequality just makes you look illiterate.

I'd love to see this argument used to get rid of legal authority to create building codes. You make a great point, and you're effectively pointing to the fact that, at least for that specific problem, the market is much more efficient and solving the problem than government regulations.

The car seats one is tough. If you've seen first hand examples of people actively choosing to forgo car seats, I'm not sure if that's a problem governments should solve. Unless the state directly claims "ownership" as it were in the child, the parent is their legal guardian and if the parent makes a terrible choice they have to live with the repercussions. We don't regulate all decisions that can harm a child, that's a tough line to draw.

The best specification is code. English is a very poor approximation.

I can’t get past that by the time I write up an adequate spec and review the agents code, I probably could have done it myself by hand. It’s not like typing was even remotely close to the slow part.

AI, agents, etc are insanely useful for enhancing my knowledge and getting me there faster.

sounds like a net win. Markdown is a superset of plain text anyway. You could make Markdown the "source" format for each page and then the web server decides at last second which MIME type header to return based on requested suffix. But even if they request .txt the page body could be identical to the
md

I have a few WIP books where Markdown is my source format for similar reasons. I then use pandoc to render to txt, html, pdf, doc or epub as desired.

How do you imagine that? First thing coming to mind is the loudness of rocket starts and powered landings. Even for airports that would be too loud. At least with current regulations. So you'd probably waste time getting to some dedicated facility, far out in the midst of nowhere to care about, and getting out of a similar hole on the other side of the trip. And again regulations regarding the closure of airspaces and seas for starts and landings, as it's currently done. Which seems rather incompatible with the current system of commercial flight ops, as it's currently done. Other relevant regulations coming to mind are evacution procedures/general survivability provisions for conventional commercial flights, which are mandatory by law.

However I turn that idea, no matter from which point I'm looking at it, I'm not seeing it going anywhere.

Won't lie, I haven't read that paper, but I doubt it contradicts what I'm saying, which is that it is unhealthy to be stressed, and arguing with randos on the internet about shit that doesn't matter most of the time (and which both of you are almost always powerless to do anything about) is going to have a negative effect on your long term health outcome. Every minute that you spend annoyed about reddit user ballLicker6969 saying something ignorant is a minute of your life you'll never get back.

being on the plane is the easy part. put bags up top -- and check the big ones so this is a simple process -- and then buckle-up and snooze.

it's the everything-else part of air travel that is fucking awful.

40+ minutes of security theater even with NEXUS and other fast-passes, lost bags, massive PITA airports, delays, and the hoards of dumb fuckin rubes who have no idea how to travel and need to haul their comically huge carry ons that somehow got through sizing + emotional support chihuahua -- a far cry from even the worst subways I've been on.

Well hopefully this will help to keep the "x86 guy" from barging into EVERY arm sbc related conversation regardless of the subject. They will ignore every argument about what the conversation is about and point out their recycled trash Lenovo uses 6W on idle while conflating idle power usage with efficiency per watt.

This is slightly off topic, but something I find myself wondering pretty regularly: if ads are pretty much universally hated by every human on earth, why do companies continue running them?

I get the obvious answer: "they work"

But do they? Do big companies have a real data-driven model to demonstrate annoying ads leading to sales?

While anecdotal, I can think of a number of specific times ads slipped through my ad blocker and I went out of my way to avoid buying anything from those companies.

Why not use optical ethernet as ‘real’ cross domain solutions do? Probably cheaper if you don’t mind eBay, and gives you an easy upgrade path to 10Gbps or more in future.

Two port NIC on the low side. Port 2 has its TX side connected to Port 1’s RX, just so the port will see a carrier and show link up. Port 1 TX goes to the high side machine’s RX, with TX left open.

From here, you have a whole ton of protocol options.

For things like syslog, you can just use a static ARP entry on the low side to forward events to the high side’s IP address via UDP.

For reliable transport, there are lots of options for reliable multicast now using erasure coding etc that don’t require a reverse channel.

RE 1. - the example still stands. Travel time is best understood as falling into buckets. Roughly:

- < 1h - can go there for lunch, or as part of running some errands;

- 2-3 hours - can fly over, have a full day of work at remote location (or sight-seeing), and get back home for supper;

- 4-8 hours - can fly over, do something useful, fly back overnight or next morning;

- > 8 hours - definitely a multi-day trip.

(There are more buckets still, if you consider long-distance travel by sea or land, and then more when considering how people perceived travel in historical times.)

As long as the travel time stays in the same bucket, reducing (or increasing) it doesn't matter much to the travelers. However, going up or down a bucket is a huge qualitative change, and one people - especially the business travelers - are more than happy to pay premium for.

So back to our supersonic planes, cutting down the LA-Seattle travel time from 3 hours to 1.5 hours (and accounting for airport overhead), doesn't affect the kind of trips people take. Cutting down travel from LA to Dubai from your 15 hours to 5 hours means it suddenly makes sense for corporate executives to fly over in person for single-day meetings, where previously it wouldn't.

This is also why it's the business customers that are always the target for such ideas - regular people are much more price sensitive than corporations, and are fine with long and hard flights if it means they can afford them. Meanwhile, paying an extra $10k to get the executive on an important meeting might actually be worth it for a large company.

The largest resource use of AI over the next 50 years will be generating entertainment structures for humans. Productivity focused AI will be the most economically useful, however it'll be far less resource intensive than the entertainment generation (generally speaking, AI tasked with driving human pleasure).

World building alone will be at least a magnitude greater in resource use than all productivity-focused AI combined (including robotics + AI). Then throw in traditional media generation (audio, images, video, textual).

AI will be the ultimate sedative for humanity. We're going into the box and never coming back out and absolutely nothing can stop that from happening. For at least 95% of humanity the future value that AI offers in terms of bolstering pleasure-of-existence is far beyond the alternatives it's not really worth considering any other potential outcome, there will be no other outcome. Most of humanity will lose interest in the mundane garbage of dredging through day to day mediocrity (oh I know what you're thinking: but but but life isn't really that mediocre - yes, it definitely is, for the majority of the eight billion it absolutely is).

Out there is nothing, more nothing, some more nothing, a rock, some more nothing, some more of what we already know, nothing, more nothing, and a lot more nothing. In there will be anything you want. It's obvious what the masses will overwhelmingly choose.

Checked your history. From a fellow skeptic, I know how hard it is to reason with people around here. You and I need to learn to let it go. In the end, the people at the top have set this up so that either way, they win. And we're down here telling the people at our level to stop feeding the monster, but told to fuck off anyways.

So cool bro, you managed to ship a useless (except for your specific use-case) app to your iphone in an hour :O

What I think this is doing is it's pitting people against the fact that most jobs in the modern economy (mine included btw) are devoid of purpose. This is something that, as a person on the far left, I've understood for a long time. However, a lot (and I mean a loooooot) of people have never even considered this. So when they find that an AI agent is able to do THEIR job for them in a fraction of the time, they MUST understand it as the AI being some finality to human ingenuity and progress given the self-importance they've attributed to themselves and their occupation - all this instead of realizing that, you know, all of our jobs are useless, we all do the exact same useless shit which is extremely easy to replicate quickly (except for a select few occupations) and that's it.

I'm sorry to tell anyone who's reading this with a differing opinion, but if AI agents have proven revolutionary to your job, you produced nothing of actual value for the world before their advent, and still don't. I say this, again, as someone who beyond their PhD thesis (and even then) does not produce anything of value to the world, while being paid handsomely for it.

Recently while interviewing for a SWE position, I was talking to the company's VP of engineering and expressed my concern over these LLM tools precisely because of the economics of it, because right now most if not all of these tools are being subsidized. Also, the environmental impact.

I was talking mainly about code generation tools, which can be completely shut down today without affecting production. Not even considering LLMs that are implemented in user facing features or customer service right now.

The guy's response: "oh but these things will surely get cheaper. Every technology gets cheaper with time. And about the environment, yeah... unfortunately there's not much we can do."

That's the level of forethought for a VP of engineering where I live.

Again, you're talking about the design of Panther Lake, the CPU IC. No one cares, it's a CPU. The news here is the launch of the Intel 18A semiconductor process and the discussion as to if and how it narrows or closes the gap with TSMC.

Trying to play this news off as "only cost cutting" is, to be blunt, insane. That's not what's happening at all.

> it’s pretty hard to make one that actually consistently works in a way that won’t accidentally burn your house down when your cat walks across the cooktop in the middle of the night.

Regardless of how the controls work, you can make a cooktop that, functionally, will not set your cat on fire: use an induction stove. Unless your cat ends up in a pan or your cat is ferromagnetic, the stove won’t heat it :)

The software in modern engines wouldn’t let you do that anyway. The engine startup process can be quite long - several minutes in a 737 MAX - while the engine’s ECU brings things to proper temperatures etc.

But with e-taxi, the startup cycle could be performed while taxiing, potentially saving airlines time on pushback as well as fuel/maintenance cost savings.

"Have you built the thing" You mean did I depend on my own intuition and the AI's "word" or did I actually test it with an outside governance system? Do I have measurements? Data? Proof?

Yes. Yes I do.

I gave you my Github. I have you my Academia profile.

Go do your homework. I'm not holding your hand through this because you're too lazy to take a "internet random" seriously.

That's YOUR loss. Not mine.

Even if you don't, you have property owners whom you'll need to either convince to sell or you'll have to get eminent domain to cross their land. Across multiple jurisdictions depending on distance covered, any one of which could delay your project by months or years with procedural objections or hearings. You'll need environmental impact studies and accomodations for the entire route. And for high-speed rail you'll need to build underpasses/overpasses at every road crossing. And once you build a rail line you're pretty committed to that route. Air travel avoids all of that.

The sandwich fallacy comment nails it. The hard part isn't the building - it's the understanding.

When you're at a particular layer of the stack, you understand your immediate customer (the layer above you) reasonably well. But two layers up? Three? You're basically guessing. And the higher you go, the more the problems become messy human problems rather than clean technical ones.

I build accounting tools. The technical work is manageable - parsing bank statements, matching transactions, posting to ledgers. But understanding why a bookkeeper categorises something a particular way, or what makes a reconciliation workflow feel "right" vs frustrating - that took years of sitting with actual users and watching them work. A database company could technically build what I build in a few months. They'd never ship something anyone actually wanted to use.

Isn’t the catalog an ad?

The issue is that anti-ad zealots won’t acknowledge that advertising is a spectrum. You can go full blown horrendous dystopia or enter into a commerce-free hermit kingdom where private property is banned and resources aren’t traded efficiently, with the end result being that everyone is poor because nobody trades anything with anyone.

A sign for your store that identifies you is technically an ad. A brand logo printed on your product is technically an ad. A positive review is basically an ad. What lengths are we going to go to ban ads?

Be honest: you’ve never bought a single useful thing that you found out about via an ad and ended up glad you saw an ad for?

That is important because the wealth of nations is often predicated on the populace being able to trade their labor.

For example, in recent years North Korea has developed their own Amazon-like delivery website for food and goods and has expanded intranet smartphone service because, obviously, fast communication and ease of transmitting a desire to buy or sell is helpful for growing an economy and keeping the nation from starving. Otherwise, why would they adopt an imperial capitalist concept like that?

I’ve settled on “sen” for seven when I want it short.

Zero could also do with being a monosyllable, but at least we have “oh” and “nil” for that.

Then there are letters. 25 of them are monosyllables (though a few like “aitch” and “kyoo” cut it fine), then w (double you) is three syllables, and not even right, it’s double vee.

Unfortunately, once I mysteriously manage to right these two wrongs, power will go to my head, and I’ll go ahead with other spelling reforms and abolishing a few stupid letters like c and x and replacing them with others for all those poor fricatives that have been loaded onto -h digraphs.

And while all that’s going on, I’ll be learning Telugu better, and it will laugh at me with its average of 2.5 syllables per digit.
Show HN: NoMe AI Authentication (a bad way to login)
by stevenslade | 2026-01-06 20:33:57+00:00
NoMe is an experimental identity verification system that authenticates you based on your personal preferences and quirks instead of passwords.

Is this a good authentication idea? Absolutely not! It was fun to explore conversational AI for identity. It has been described to me as "the most annoying thing ever built."

During enrollment, it asks you creative questions like:
- "What music do you NOT like when working?"
- "What notification sound makes you check your phone immediately?"
- "If you could only have one condiment for everything, what would it be?"

At login, it challenges you with variations of those questions, sometimes flipping the polarity ("What do you dislike?" instead of "What do you like?"), and adding honey pot questions to check consistency.

Under the hood: semantic embeddings, NLI scoring for contradiction detection, and GPT-4o-mini for question generation and answer canonicalization.

Ah yes Flash. I had just started learning how to build static HTML sites and was going down the road of learning flash instead just as I saw Steve Jobs came out in opposition of it.

I decided to turn back to regular HTML/CSS and then PHP.

Regulation is only a policeman. It doesn’t innovate.

Competitive markets do innovate. I watch YouTube live instead of Twitch (many streamers double stream) precisely because the former has skippable ads.

Regarding the kiosk, I wholly expect that an unattended device with YT on auto play will ratchet up the length/frequency of ads as long as they're never skipped.

Someone who falls asleep watching YouTube will skip ads, unless they're asleep.

The idea is that if YT can infer that someone is asleep (location, no movement, no sound, low light, night) that they can show the longest, most skip-inducing ads that they've got since they know they won't be skipped.

The difference between the kiosk and the sleeper is that if the sleeper gets a 20 minute ad at 2pm while they're eating lunch, they'll skip it. YT is incentivized to show the most profitable ad that someone won't skip.

The value in identifying sleepers isnt showing a long ad, it's showing a long ad with the certainty that it won't be skipped.

True, the engines need to be warmed up and the hydraulics need to be pressurised, but given e.g. airbus recommends single engine taxi without APU (SETWA) warming up the engines probably doesn't take that long in the grand scheme of things. Definitely not the 15~25mn of taxi. From the sources I can find, "normal" warmup takes 2~5mn depending how long ago the engine was shut down, unless outside temps are exceptionally low, and you can do that while reaching the end of your taxi.

What is the real AI cost at which point this is an issue for a corporation you think? I contract at a place that gives $1,000/month budget per SWE (5 Max accounts) and I am sure if the price was 10x that no one would even blink.

It is basically cost-benefit analysis just like with any other cost (and there is always option to revert to local?)

>>The bottleneck for success often is not knowledge of the tools, but lack of understanding of the customer needs.

THIS!! A Thousand Times This!

I have had many successful projects putting the coders in direct contact with the end users.

In contrast, every time a manager is inserted between the real user requirements and the code, the project descends a lower ring of endless-feature-creep hell, doubles in length, and doubles it's likelihood of failure.

Yes, managers are needed to provide some insulation from very noisy and chaotic feature requests from users, but insisting on at least some frequent time with some actual coders in contact with actual users pays massive dividends.
