As far as I know drones usually are one step forward against jamming capabilities of the defence. Jamming device that blocks all frequences costs a lot in money, consumes a lot of power and can be mounted only on a vehicle. And then fiber-optic drones join the game. Infantry not in the vehicle is unprotected and is unable to defence itself. The only chance to survive is to run faster than drone which can be achieved using bikes. But that is not a solution at all. Not all drones are cheap. What about FPV with night vision cameras? Even if it costs a lot but gives you superiority you can benefit from it in some critical missions and then mass production will reduce the cost. I suppose going from FPV drones to unmanned AI-drones will change everything like when jet aircrafts replaced propeller aircrafts.

There is a well known saying in TikTok - that you are responsible for creating your own For You Page (FYP).

Everytime I get a pretty girl doing a thirst trap little dance or anything else a not productive use of my time, I click 'not interested'. Everytime I get something of interest I click like or follow the creator or comment on it.

I get most of my tech news from TikTok. If open ai drops a new model or whatever Tiktok knows I want to know.

So the article is wrong, it's not wasted time if the algo is tuned well.

Japan is literally the definition of a crisis.

"Kishida said Japan was “on the cusp of whether it can maintain its societal functions”...

over 50% of companies have shortage of labour; and that's despite being heavily robotic and automated.

They have extreme amount of debt, but also future debt of social security and healthcare costs from elderly that cant be paid for.

Yes they cut pension benefits and changed eligibility. You have to pay way more co-pay in healthcare.

The IMF has Japan collapsing significantly in the early 2030s due to pension pressures.

I really wish this were built into imgui as a first-class use case instead of requiring a hodgepodge mix of unofficial hacks.

I recall the author posting an imgui update saying this will be an officially supported mode, but AFAIK it's still not the case. Otherwise I would be building all my applications with imgui going forward.

Re-rendering the screen, even if it's fast, incurs a lot of memory bandwidth to draw everything and swap framebuffers etc. Not something you'd like to happen on mobile, in particular. Just because the waste is "small", doesn't mean it's acceptable.

Many of us are guilty of adding little to almost no information about product installation, product care tips and benefits in our product description. I have built a Shopify app that does all the for free. You only have to pay for OpenAI or Gemini or Claude Api, that also directly to these AI models.

If you don't event want to spend a single penny, feel free to use free AI model we have integrated so you can use our app for absolutely FREE.

Since writing product description, meta title and description and ALT Text is not rocket science I am not planning to charge anything for these features. I would love to see all of you gain some traffic through SEO.

Courtesy of AI:

> Social democracy and democratic socialism are related but distinct political ideologies. Social democracy, often associated with the Nordic model, focuses on regulating capitalism to create a strong welfare state and reduce inequality through social programs, while generally supporting a mixed economy with private ownership. Democratic socialism, on the other hand, envisions a more fundamental transformation of the economic system, often including greater public or worker ownership and economic democracy, while also emphasizing democratic principles.

All countries in West Europe implement social democracies. They greatly outperform the US.

Countries in Eastern Europe are still enduring their legacy of communism/democratic socialism, but 30 years ago they experienced a radical swing towards the blend of neoliberalismo professed by the US.

Lastly, you look at data showing how the US greatly underperforms in key quality of life metrics, and the conclusion you opt to extract is cherry-pick those to look down on? That's tragic.

Hey HN,

Today I woke up with the idea of making an agent-friendly version of hacker news. The coolest would be to also make it able to login, but that didn't work out, since I got blocked.

However, I made an oauth provider for HN, and it works on my machine. Unfortunately the IP gets blocked in production, so this isn't gonna work out. Even with a residential proxy, I started to get Captcha protection.

I'd love to make a 'login with Hackernews' so third party apps can build cool stuff with it. The code's all there.

Can you whitelist me?

Cheers, Jan

The demographics of programming languages choosen/picked up by new generations of foss developers.

I guess there will be non-technical frictions between rust and C in the linux project for as long as the GNU/linuxers exist. And like the OP, it can be seen as a matter of accessibility.

I wonder if aerospikes were popular as an idea in the J-2 engine ~Apollo era since USA only had gas generator engines (and expander RL-10).

You can't get to very high chamber pressures with those, and then maybe aerospike was a way to work around the limitations.

Then XLR-129 and SSME came along with staged combustion cycle and you can just have higher pressure engines. They can both run at sea level and still have a decent efficiency in vacuum.

The linear aerospike for X-33 was kind of a neat tech demo and fit in with the whole shape of the vehicle and composites, non-tubular tanks and large base area. Maybe too many new things at once in retrospect.
Launch  HN: Empromptu.ai – Agentic AI Building AI Apps
by anaempromptu | 2025-06-27 11:31:28+00:00
Hey HN! We're Empromptu.ai, an AI app builder that builds AI apps (RAG, models, evals all built in every app)

Demo: https://www.youtube.com/watch?v=w25XhUaPfls

We started Empromptu after burning through thousands of credits on AI builders and hitting the same problem: cool looking prototypes or demos that break with real users.

The issue wasn't the building process, it was accuracy. Most AI applications plateau at 60%~ reliability, which is fine for prototypes but it's unusable in production. We realized these tools aren't really "AI app builders", they're website builders that happen to use AI.

We wanted to solve the hardest problem first: making AI applications actually work reliably.

Our approach centers on what we call dynamic optimization. Instead of cramming every possible scenario into one massive prompt (which confuses LLMs), our system adapts contextually. A travel chatbot automatically knows to mention LAX for Los Angeles vs. Pearson for Toronto. This consistently delivers 90%~ accuracy versus the industry standard 60%~.

But accuracy alone wasn't enough because we also needed to solve the builder gap:

- Simple builders (Lovable, Bolt): Create static websites, not AI applications

- Complex ML tools: Require dedicated teams most startups don't have (Arize, Voxel51) - we've also heard from both technical and non-technical founders that they found these tools very complex

- What's missing: Tools that build applications where AI is embedded functionality

So we built AI agents with optimization built-in. Users just type what they want to build and our agents handle the full development pipeline: creating applications with embedded models, RAG and intelligent processing. You can deploy to your own infrastructure via Netlify, GitHub or download it directly since you can run it locally.

The result: Startups, solo hackers and enterprises can build production-ready AI apps without hiring a dedicated ML team.

Waitlist: https://empromptu.ai

We'd love feedback from the HN community — esp. if you've hit similar accuracy problems or thoughts on the technical approach.

I am 2 months into having a Quest 3 and I absolutely love it but the resolution feels like it is probably 2 generations away still.

I am sure it is better than any CRT monitor I use to work on all day but my standards are just so much higher with how good monitors are.

I think if you got use to working on it though, you could manage no problem.

> There are in-flight proposals for very low-level DOM update primitives, like DOM Parts, which target framework implementations, but I think higher-level APIs like full declarative templating can take even more load off, help prove out and complete the lower-level API proposals, and be really impactful for developers and users.

There is an alternative suggestion to DOM parts which might be a better bet: https://github.com/whatwg/dom/issues/736

> App Store apps that communicate and promote offers for digital goods or services will be subject to new business terms for those transactions — an initial acquisition fee, store services fee, and for apps on the StoreKit External Purchase Link Entitlement (EU) Addendum, the Core Technology Commission (CTC). The CTC reflects value Apple provides developers through ongoing investments in the tools, technologies, and services that enable them to build and share innovative apps with users.

It is not very clear from the press release: will developers still have to pay Apple even if their apps are coming from 3rd party AppStores? And if so, how much?

Why?

By the definition of ptrdiff_t, ISTM the size of any object allocated by malloc cannot be out of bounds of ptrdiff_t, so I'm not sure how can you have a useful size_t that uses the sign bit?

We have a paper under review that's gonna be up on arXiv soon, where we test this for ~10,000 words and find consistent decline in counting ability based on how many characters are in the tokens where the target character appears. It seems that models know "which character" is a single-character token but really doesn't get much about the inner composition of multi-character tokens.

Yes, of course for web applications you can't do full page reload (you weren't either back in the days, where web applications existed in form of java applets or flash content).

Let's face it, most uses of JS frameworks are for blogs or things that with full page reload you not even notice: nowadays browsers are advanced and only redraw the screen when finished loading the content, meaning that they would out of the box mostly do what React does (only render DOM elements who are changes), meaning that a page reload with a page that only changes one button at UI level does not result in a flicker or loading of the whole page.

BTW, even React now is suggesting people to run the code server-side if it is possible (it's the default of Next.JS), since it makes the project easier to maintain, debug, test, as well as get better score in SEO from search engines.

I'm still a fan of the "old" MVC models of classical frameworks such as Laravel, Django, Rails, etc. to me make overall projects that are easier to maintain for the fact that all code runs in the backend (except maybe some jQuery animation client side), model is well separated from the view, there is no API to maintain, etc.

I can't tell if this comment was written in jest or not.

It's always protocol improvements and 'it's coming in the next version's or 'msc #xxxx just got approved' with Matrix.

It's always someone saying 'oh this next version fixed all that' and then someone says 'well what about mobile' or 'what about desktop's and then someone says 'actually it doesn't fix it there.'

I'd love matrix to be the solution to my communication problems but it just isn't.

Intelligence isn't one dimensional, but the parameters do tend to have a correlation on average. Higher IQ usually means higher other forms of intelligence -- on average.

That being said, the caveat "on average" must always be added. On average, on average, on average. Same goes with anything about average tendencies of different genders. On average, on average, on average, averages across large groups do not map to individuals in that group. Emboss that on a mallet and bash people over the head with it until they get it.

I do wonder if there might be some conservation at play in some individual cases -- which kinda matches what you said. There is only so much brain tissue. If you're hyper-good at some narrow kind of analytical intelligence (coding!) maybe some of that brain tissue is borrowed from other things it might be doing like understanding other meat sacks.

I appreciate that this might be true for a large portion of US-americans, but the country isn't doing anything, the people continually voted into power takes that ability away, which can be adjusted bi-annually.

IQ is a rough measure of how big the engine is, like horsepower in a car. It says nothing about the quality of the driver or anything else about the car. A car with a huge engine in the hands of a bad driver can ram itself into a tree with great force.

In my experience I've met a ton of extremely high IQ people who believe insane things: the Moon landings didn't happen, bizarro political theories that fall apart if you look at them funny, occult mumbo jumbo, Scientology, vaccines cause autism and similar (RFJ Jr. probably has a high IQ), etc.

I wonder if having a high IQ means you can delude yourself better. Whether God can build a mountain he can't climb over may be a paradox, but humans with high IQ can absolutely create traps for their own mind they can't think their way out of.

I've also found that high IQ correlates -- at least in my sample -- with authoritarian political beliefs, with a roughly equal split between authoritarian leftism (Communism / tankie Marxism, technocratic socialism) and authoritarian rightism (race nationalism, fascism, neoreaction, authoritarian traditionalism / theocracy). I think this stems from an intuition on the part of the person that because they seem smarter than average and have trouble running their own life, there's no way an average person can be part of self-governing. I think they're both underestimating other people and overestimating the inherent efficacy of "smart" people.

It depends what you use it for. I worked on a interbank messaging platform that normalised everything into a series of standard xml formats, and then used xslt for representing data to the client. Common use case - we could rerender data to what a receiver’s risk system were expecting in config (not compiled code). You could have people trained in xslt doing that, they did not need to be more experienced developers. Fixes were fast. It was good for this. Another time i worked on a production pipeline for a publisher of education books. Again, data stored in normalised xml. Xslt is well suited to mangling in that scenario.

Nice work. Getting at obscured firmware is the next best thing to open firmware. (Well, or firmware that's simply not there, if it's not open.)

I've had several Supermicro servers at home over the years, and I've kept the one that doesn't include the IPMI BMC. (You can see the unpopulated pads on the board where the Winbond(?) package was in a different variant of the server I had.) Fewer things to go wrong.

It's the degree of things. I live in Ireland, in a village of a few thousand people a few km outside the city, what you might call a "suburb" in the US. I don't even have a driver's license. It's rarely an issue and can go about my life by foot. bike, and public transport.

It felt like a great idea at the time, but it was incredibly slow to generate all the HTML pages that way.

Looking back I always assumed it was partly because computers back then were too weak, although reading other comments in this thread it seems like even today people are having performance problems with XSLT.

You’re missing the point. An LLM is not going to memorise a whole book just because it’s seen a few copies. An LLM might be able to memorise the Bible in particular simply because Bible quotes are everywhere. There is a vast difference between being able to find a handful of copies online and having it constantly quoted everywhere that humans communicate. Bible quotes get literally everywhere. People put them on bumper stickers, tattoo themselves with it, put it in their email signatures, etc. Bible quotes are so omnipresent, they have become part of our language – a lot of idioms people use every day come from the Bible.

The Bible isn’t just a book, it’s been a massive part of human culture for millennia, to the point of it shaping language itself. LLMs might be able to memorise the Bible, but it’s not because they can memorise books, it’s because the Bible is far more than just a book.

The faux-gravitas tone and the blurred content that's on Wikipedia is the worst kind of AI ckickbait. LLM vendors don't have any authority we don't let them have, they have an EULA and some psycho cult leader type as a hype man.

I really like the immediate mode GUI (IMGUI) paradigm. The other day, I looked into whether any web-based IMGUI libraries existed. It seems that HTML and the DOM are designed so differently from IMGUI that such an approach doesn't really make sense, unfortunately, unless everything is rendered manually in a canvas, WebGL, or WebGPU, which brings its own set of challenges.

Because editors stopped trying to do WYSIWYG. It's not that the demand isn't there. They stopped trying about the time monitors went from a couple of quite similar fixed widths of 600/768 to more. Then smart phones came along and really killed the WYSWIG editor. I worked with Silverlight for a year in the late 2000s, and even by then WYSWYG editors were struggling. You sorta still had some for flash and stuff. They were trying to bring back a WYSWIG editor for it (and for WPF in general after silverlight flopped). But it was pretty clunky still. There's a lot of hard problems about how you anchor elements, how things scale, that are much easier to express in code than in a properties panel.

You can see the demand in the sheer number of WYSWYG editors for the web.

But for development, basically all the big players stopped trying or died for other reasons. I just think no-one's got the will to try it.

I think it could be a huge opportunity for someone. Right now, with AI coming to the fore in development, seems to be when it would become absolutely killer for less code orientated people making their own apps by adding/dragging controls around and telling an AI what each control should do. All without a programmer involved. The AI could even "solve" the hard problem of a good responsive WYSWYG editor by making assumptions of how the user probably wants the controls anchored.

So I think that's the market we'll see a WYSWIG editor emerge again for.

Don’t you need to look at different failure scenarios or patterns in orbit due to exposure to cosmic rays as well?

It just seems funny, I recall when servers started getting more energy dense it was a revelation to many computer folks that safe operating temps in a datacenter should be quite high.

I’d imagine operating in space has lots of revelations in store. It’s a fascinating idea with big potential impact… but I wouldn’t expect this investment to pay out!

This is so twisted out of all proportion I find it difficult to believe you are being genuine.

A government giving an ID to somebody is not propping up “an untenable business model”.

Saying “I don’t want you to access my service” is not “controlling people on the Internet”.

I find this: https://i0.wp.com/biblequestions.info/wp-content/uploads/202... surprisingly easy to read; although obviously I already know a lot of what's coming, I can still pick up on the working I'm unsure of. That said, words like "debts" still threw me b/c of the 'd' looking like a 'b' and vice-versa.

I wonder if typesetting like this can be combined with https://bionic-reading.com/ ? The above emphesises text is a regular way, but I reckon you could train an AI on people reading different empesised text, and track where they slow-down or mis-speak; and as such figure out how a different emphesis could improve comprehension (of the text)?
