It's the "same amount of time" part that is blatantly wrong. Yes geometry has an effect but there is zero reason to believe leading edge particles, at the same time point, must rejoin at the trailing edge of a wing. This is a misconception at the level of "heavier objects fall faster." It is non-physical.

The video in the Cambridge link shows how the upper surface particles greatly overtake the lower surface flow. They do not rejoin, ever.

By 99 it wasn't that bad. I remember screaming along with V.92 56k modems. Futurama episodes were about 50mb encoded as RealVideo and took a mere two and a half hours to download o.0

(and it really was v.92; I still have the double-bong towards the end of the handshake emblazoned in my memory)

This hits home. We're building business intelligence APIs around entity resolution, and the buyer/user split gets messy when you have engineering, product, and data science teams all involved.

Engineers immediately understand why matching messy company data is a nightmare, but executives just see delayed projects without grasping the technical complexity.

We're seeing more success lately with "your team burned N months on data matching that should've taken weeks" rather than explaining what entity resolution even is. We're talking to one company right now that's spent 10 years building their own entity resolution system and it still doesn't work well.

But even then, it depends on the company and what they're trying to do.

It wasn't long ago that test-time scaling wasn't possible. Test-time scaling is a core part of what makes this a breakthrough.

I don't believe your assessment though. IMO is hard, and Google have said that they use search and some way of combining different reasoning traces, so while I haven't read that paper yet, and of course, it may support your view, but I just don't believe it.

We are not close to solving IMO with publicly known methods.

I am testing out gpt-5-mini for a RAG scenario, and I'm impressed so far.

I used gpt-5-mini with reasoning_effort="minimal", and that model finally resisted a hallucination that every other model generated.

I'll run formal evaluations next.

Great, they can use standards that aren't targeted at running services for the general public. It seems like the requirements already diverged.

Drop attestation from passkeys, and I become a promoter. Keep it, and I suggest people stay away.

If it's not something anyone intends to use on public services, this should be uncontroversial. Dropping attestation simplifies implementation, and makes adoption easier as a result.

From Wikipedia

>In fact, theory predicts – and experiments confirm – that the air traverses the top surface of a body experiencing lift in a shorter time than it traverses the bottom surface; the explanation based on equal transit time is false.

So the effect is greater than equal time transit.

I've seen the GPT5 explanation in GCSE level textbooks but I thought it was supposed to be PhD level;)

There's a need for better indexing. Seems like they switched search to pure embeddings and it doesn't work. Making performant hybrid search is hard in the sense that you cannot combine indexes. Ideally something like embedding, text match and quality vector. I had PoC that worked great when using those but making it scale is hard with reasonable latency.

If something like this exist please educate me as this would make tons of products better.

What most people don't realize is that Alzheimer's - and its friend FTD - are terminal diseases with life expectancy just as bad as many cancers. Hardly anyone makes it to 5 years after diagnosis. The bodily degeneration that eventually results in the patient being utterly unable to function is heartbreaking. Forgetting things is a relatively minor symptom. It's also terrible on the family members of the patient whose mental health also suffers along the way.

People have been making these for a while. I used to see them on Flash game sites all the time as a kid. It'd be "Windows 96" or "Windows XD" or whatever else they decided to call it. They all had a start menu, notepad, maybe a calculator, and maybe a Minesweeper clone, and not much else.

Judging by the amount of Windows startup sound compilation videos out there, "the kids yearn for desktop UIs" might just be a little more common than you think.

Problem is, I assume, being stuck relying on some brittle apps that might or might not still run after some OS upgrade or after buying a new device. Like the DOSBox app I use on my Android phone is amazing but knowing that eventually it will suddenly expire (when the developer abandons it), like the previous one, makes me enjoy the games a lot less than I do when I have a more stable platform set up like when playing using some fully open source emulator on a rpi or x86 desktop pc.

I'd love to see a product comparison.

Other countries have different power and incentive structures. In Germany, both the state and labor are represented at the ownership level. In Japan, corporate and social expectations are completely different.

Companies can also 'borrow from the future' by reducing R&D or stretching a product lifecycle from 6 years to 10 or more. Over that time, they will lose some market share as people lose enthusiasm for their product. Of course, if all the car companies had a 10 year product cycle, then consumers would pay less for engineering changes etc; but everyone has an incentive to 'defect' so they can capture more market share.

It is generally believed that competition benefits consumers overall; but there is no single system that will magically improve every metric.

If you've been satisfied with blaming an organization or a person, then an explanation can feel like an excuse, because I'm asking you to pick the problem back up again with added complexity.

It wasn't you, but I was responding to this

>"It's the White House that wanted Trump to be candidate. They played Republican primary voters like a fiddle by launching a barrage of transparently political prosecutions just as Republican primaries were starting."

This really did sound like it " suggest political astuteness"

And, so all the way back, I responded sarcastically. If Democrats could 'Play Republicans like a fiddle", because they wanted Trump to win the primary. Then what happened? Where did all that 'astuteness' go.

yep that'll be in their PDS. but that's the nature of the beast. you as the user control your data and your posts.

So if there's a large scale exodus from bluesky, as long as full backfills of the network exist, you'll be able to reconstruct your CAR files, etc even if your PDS dies.

So yes if they die all the comments disappear but people can reconstruct their history and move it to other PDS like blacksky, northsky, or others who are getting ready to start onboarding/open enrollment.

TLDR it'd be a bit rough if they died overnight but if it was a slow death and people had a bit of warning you'd see people move on to other PDS without issue.

I've said it before, and I'll probably keep saying it forever: bad writing predates AI. Overly verbose writing predates AI. Not all the bad writing you see is AI, lots of it is still the good old fashioned kind.

Not that inserting an aside about a different language is bad writing. It's also weird enough that it's exactly what I would not expect an AI to do (except perhaps under very odd and specific circumstances). "It's clearly AI" has become a catchall for any writing that people find even mildly bad or surprising.
by billmalarky | 2025-08-07 18:24:13+00:00
Hi Swyx I always appreciate your insights, something you wrote really resonated with a personal theory I've been developing:

>"While I never use AI for personal writing (because I have a strong belief in writing to think)"

The optimal AI productivity process is starting to look like:

AI Generates > Human Validates > Loop

Yet cognitive generation is how humans learn and develop cognitive strength, as well as how they maintain such strength.

Similar to how physical activity is how muscles/bone density/etc grow, and how body tissues maintain.

Physical technology freed us from hard physical labor that kept our bodies in shape -- at a cost of physical atrophy.

AI seems to have a similar effect for our minds. AI will accelerate our cognitive productivity, and allow for cognitive convenience -- at a cost of cognitive atrophy.

At present we must be intentional about building/maintaining physical strength (dedicated strength training, cardio, etc).

Soon we will need to be intentional about building/maintaining cognitive strength.

I suspect the workday/week of the future will be split on AI-on-a-leash work for optimal productivity, with carve-outs for dedicated AI-enhanced-learning solely for building/maintaining cognitive health (where productivity is not the goal, building/maintaining cognition is). Similar to how we carve out time for working out.

What are your thoughts on this? Based on what you wrote above, it seems you have similar feelings?

Is there a name for this theory?

If not can you coin one? You're great at that :)

> Nothing having to do with "good faith", but that style isn't really definable.

We have something called AI which knows everything, maybe they should ask them. It's very fashionable. Even if the definition is wrong, it's an AI, it can make no wrong. That's what I've heard.

> I'm not sure why all the drama, because who even cares? The reason why I watched Ghibli movies wasn't ever about the particular looks.

Because a man and a studio which draws their movies by hand [0], frame by frame, and spend literal years doing it for a single movie deserves some respect even if you don't care about the art style.

Even a top notch studio like Pixar can pump a couple of minutes per week [1].

Doing this type of work takes immense dedication, energy and time. If you think it's worthy of nothing, I can't say anything about it. I deeply respect these people for what they do, and I'm equally thankful.

> You better hope it stays at characters, or we're going to have a mess of lawsuits of people and organizations suing each other because they draw eyebrows this particular way. I fail to see why is that at all desirable.

Maybe they should drink their own poison to understand what kind of delicate balances they're poking and prodding. The desire for more monies in spite of everything should have some consequences.

This is true. In the simple implementation, your blog would probably lose most comments if BlueSky went down and most users don't migrate to a new PDS.

However, atproto data is append-only and cache-friendly. It wouldn't be hard to record historical comments and join them to the ones returned by the live query. (I'm probably just going to script periodic backups for mine and worry about displaying them when/if BlueSky does dissappear.)

This is great. My tip: don’t spend money on LSAT prep (unless you have no impulse control and can’t learn from a book). Just take practice tests, and when you get an answer wrong, carefully articulate exactly why each of the wrong answers was wrong and the right answer was correct. At least when I took it (17 years ago now) there was always a clearly right answer and three clearly wrong answers. I’ve never seen a single LSAT where that wasn’t the case. During the test you should be able to not only identify the correct answer, but articulate in your head why each other answer is clearly wrong.

It's not about being toxic, it's about being honest. There is absolutely nothing wrong with OpenAI saying "we're focused on solid, incremental improvements between models with each one being better (slightly or more) than the last."

But up until now, especially from Sam Altman, we've heard countless veiled suggestions that GPT-5 would achieve AGI. A lot of the pro-AI people have been talking shit for the better part of the last year saying "just wait for GPT-5, bro, we're gonna have AGI."

The frustration isn't the desire to achieve AGI, it's the never-ending gaslighting trying to convince people (really, investors) that there's more than meets the eye. That we're only ever one release away from AGI.

Instead: just be honest. If you're not there, you're not there. Investors who don't do any technical evals may be disappointed, but long-term, you'll have more than enough trust and goodwill from customers (big and small) if you don't BS them constantly.
by nine_k | 2025-08-07 18:25:18+00:00
Cynically, the AI is ready to replace professionals, in areas where the stakeholders don't care too much. They can offer the services cheaper, and this is all that matters to their customers. Were it not so, companies like Tata won't have any customers. The phenomenon of "cheap Chinese junk" would not exist, because no retailer would order to produce it.

So, brace yourselves, we'll see more of this in production :(

Show HN: AI-powered cover letter generator based on resume and job description
by Mikasa1 | 2025-08-07 18:26:10+00:00
Hi HN! I built PayRankJobs(https://payrankjobs.ai), an AI job matching service, and one of the most popular features has been the automated cover letter generation.

Here's how it works: • Upload your PDF resume once • AI extracts your skills, experience, and background • Click "Create Cover Letter" on any job match in your email • An LLM analyzes both your profile AND the specific job description. • Generates a personalized cover letter tailored to that exact role • Emails it to you

What makes it different from generic cover letter tools: - Uses your actual resume data (not templates) - Analyzes the specific job posting requirements - Matches your background to role needs - Avoids generic "I'm perfect for this" language

The system has generated 500+ cover letters so far.

Tech stack: Cloudflare Workers, OpenAI o3, PostgreSQL with pgvector, queue-based architecture for reliability.

Try it: Upload a resume at https://payrankjobs.ai and you'll get job matches with cover letter options.

Would love feedback on the AI prompting approach or the overall UX!

Approval ratings are unscientific, fleeting, and wildly variable, even among Presidents that go on to be reelected. It is a stat you take with a grain of salt, especially 6 months into a presidency. Even the polls for the actual election, which get far more money to spend, were wildly inaccurate especially in recent elections.

If Trump's moves pan out in the positive for American people over the next year or two, controversial as they may be in the present, then sentiment will increase, plain and simple.

JD Vance is quite popular among Republicans and reasonably popular among independents, which is all you need to win the presidency. The Democrats, on the other hand, have no heir apparent and have quite a few structural issues within their own party at the national level. We'll see what the actual field looks like in 2028 but that is a long ways off and a lot will change between now and then.

“The Cybertruck’s aggressively angular and futuristic design, paired with its unpainted stainless steel exoskeleton, sets it apart from competitors typically using painted steel or aluminum bodies,” the Air Force wrote in contract documents. “Additionally, its 48V electrical architecture provides superior power and efficiency, a feature that rivals are only beginning to develop.”

This reads like Tesla marketing material. I don't see how the voltage of the electrical system would matter to the type of munitions being deployed against the vehicle

Again, you're not wrong, it's just irrelevant for most audiences. The very fact that you have to say this:

> Yes geometry has an effect but there is zero reason to believe leading edge particles, at the same time point, must rejoin at the trailing edge of a wing.

...implicitly concedes that point that this is subtle. If you gave this answer in a PhD qualification exam in Physics, then sure, I think it's fair for someone to say you're wrong. If you gave the answer on a marketing page for a general-purpose chatbot? Meh.

(As an aside, this conversation is interesting to me primarily because it's a perfect example of how scientists go wrong in presenting their work to the world...meeting up with AI criticism on the other side.)

Productivity gains aren't universal, agreed there for sure, though we have long since moved past needing to optimize productivity for the basics. Collectively we're addicted to trading our time and effort for gadgets, convenience, and status symbols.

I'm not saying those are bad things, people can do whatever they want with their own time and effort. It just seems obvious to me that we aren't interested in working less over any meaningful period of time, if that was a goal we could have reached it a long time ago by defining a lower bar for when we have "enough."

> that's a perspective that's very clear in hindsight,

It was clear at the time at least to people like Keynes who wrote a book on the subject: The Economic Consequences of the Peace.

"My purpose in this book is to show that the Carthaginian Peace is not practically right or possible. Although the school of thought from which it springs is aware of the economic factor, it overlooks, nevertheless, the deeper economic tendencies which are to govern the future. The clock cannot be set back. You cannot restore Central Europe to 1870 without setting up such strains in the European structure and letting loose such human and spiritual forces as, pushing beyond frontiers and races, will overwhelm not only you and your "guarantees," but your institutions, and the existing order of your Society."

> The idea is to do it on a high-margin, low-volume product so that any hiccups can be absorbed in the accounting

As opposed to actually eliminating the source of the hiccups.

The Japanese auto manufacturers moved their high-volume, low-margin assembly to the US and succeeded. They started by importing nearly every component and then steadily replaced them with locally-built components.

If Apple was serious, that’s what they would have done. You know, like how they did it in India. Like how they did it in Malaysia. Like how they did it in Vietnam.

Apple’s not serious about US-based manufacturing until proven otherwise. Gold statues don’t prove anything.

>Air over the top has to travel farther in the same amount of time

There is no requirement for air to travel any where. Let alone in any amount of time. So this part of the AI's response is completely wrong. "Same amount of time" as what? Air going underneath the wing? With an angle of attack the air under the wing is being deflected down, not magically meeting up with the air above the wing.

One example in my field of engineering is multi-dimensional analysis, where you can design a system (like a machined part or assembly) parametricially and then use an evolutionary model to optimize the design of that part.

But my bigger point here is you don't need totally general intelligence to destroy the world either. The drone that targets enemy soldiers does not need to be good at writing poems. The model that designs a bioweapon just needs a feedback loop to improve its pathogen. Yet it takes only a single one of these specialized doomsday models to destroy the world, no more than an AGI.

Although I suppose an AGI could be more effective at countering a specialized AI than vice-versa.

The "Galactic-Scale Energy" post is a great illustration that a constant percentage growth rate eventually hits hard limits imposed by physics.

Posts like abetusk's are a great illustration that "the solar budget" is a very generous energy budget. That may seem too obvious to mention, but in 20th century ecology literature (or even as recently as the early 2010s) living within "the solar budget" was often conflated with a low-energy, deindustrialized future. Constant growth fueled by sunlight (or anything else) can't go on indefinitely, but there's also no prospect that a sunlight-fueled world would have less energy available than the old fossil-fueled one.

The company I founded previous faced this problem - we were selling to a part of the development team that often had no clout in making financial decisions. We were able to sell to smaller companies and larger ones that happened to have people who had enough power to purchase. But the majority of companies had super long sales cycles where we had to work with them to prove out the cost savings to people higher up. Most of the time this went nowhere and cost us a ton of time. It wasn't the only reason the company failed, but a major contributing factor. Glad to see people talking about it because it's something a lot of small b2b companies face and there's surprisingly little advice on it.
