Oh, that's a very specific crack. This is an extrusion error. The extrusion temperature is dropping too low while it's still over the internal die. The thicker peaks cool more slowly than the thinner flats, remaining at a weaker temperature longer, and they're pulled apart by accumulating contraction.

These cracks usually aren't obvious until they meet a conflicting load. For example, tapping threads up the end without supporting the work correctly. It's not like this is a load bearing part, they could get around this issue with a little care. Holding the work in a hex collet during tapping is cheap, adds efficiency, and would solve the problem. Sending feedback to the extruder is free and usually effective. Or maybe the product is moving well enough on brand equity that it's not worth bothering.

It's kind of interesting that you're claiming a slippery slope argument, when the words we use to describe incest Oedipal and Electra complex come from wildly popular pre-CE fictional accounts of incest.

As for violence, that's because such acts on film were illegal. Pornography was tightly regulated before this era of free speech. Even now the UK, is constantly trying to maintain BDSM porn as criminal [1] and Australia has similar tight restrictions [2]. This is to say nothing of the countries where pornography is completely banned: China, North Korea, Indonesia, Pakistan, Bangladesh, Vietnam, Iran, Saudi Arabia, Syria, Turkmenistan, Belarus, Bulgaria, Djibouti, Egypt, Eritrea, Ethiopia, Iceland, Iraq, Kyrgyzstan, Malaysia, Malta, Myanmar, Sudan, Thailand, Turkey, Uganda, United Arab Emirates, Uzbekistan, Yemen.

So if the question is why do you see more of Y in XXX, it's because it is now allowed so content is created to satisfy needs that were already there.

I think the primary thing you're missing is that Qwen3-235B-A22B-Instruct-2507 != Qwen3-Coder-480B-A35B-Instruct. And the difference there is that while both do tons of code RL, in one they do not monitor performance on anything else for forgetting/regression and focus fully on code post-training pipelines and it is not meant for other tasks.
Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker
by yujonglee | 2025-07-29 16:24:08+00:00
Hi HN! We're Yujong, John, Duck, and Sung from Hyprnote (https://hyprnote.com). We're building an open-source, privacy-first AI note-taking app that runs fully on-device. Think of it as an open-source Granola. No Zoom bots, no cloud APIs, no data ever leaves your machine.

Source code: https://github.com/fastrepl/hyprnote Demo video: https://hyprnote.com/demo

We built Hyprnote because some of our friends told us that their companies banned certain meeting notetakers due to data concerns, or they simply felt uncomfortable sending data to unknown servers. So they went back to manual note-taking - losing focus during meetings and wasting time afterward.

We asked: could we build something just as useful, but completely local?

Hyprnote is a desktop app that transcribes and summarizes meetings on-device. It captures both your mic input and system audio, so you don't need to invite bots. It generates a summary based on the notes you take. Everything runs on local AI models by default, using Whisper and HyprLLM. HyprLLM is our proof-of-concept model fine-tuned from Qwen3 1.7B. We learned that summarizing meetings is a very nuanced task and that a model's raw intelligence (or weight) doesn't matter THAT much. We'll release more details on evaluation and training once we finish the 2nd iteration of the model (still not that good we can make it a lot better).

Whisper inference: https://github.com/fastrepl/hyprnote/blob/main/crates/whispe...

AEC inference: https://github.com/fastrepl/hyprnote/blob/main/crates/aec/sr...

LLM inference: https://github.com/fastrepl/hyprnote/blob/main/crates/llama/...

We also learned that for some folks, having full data controllability was as important as privacy. So we support custom endpoints, allowing users to bring in their company's internal LLM. For teams that need integrations, collaboration, or admin controls, we're working on an optional server component that can be self-hosted. Lastly, we're exploring ways to make Hyprnote work like VSCode, so you can install extensions and build your own workflows around your meetings.

We believe privacy-first tools, powered by local models, are going to unlock the next wave of real-world AI apps.

We're here and looking forward to your comments!

"Why would AI be any different?"

It might not go any differently, but I think all us folks here have an opportunity to make it different.

Any product needs to pursue enough engagement that the user actually gets value. I have a bunch of apps I installed aspirationally, but don't use. But if we're willing stop ourselves once we have enough, we can pursue enough engagement and enough revenue. But if you tie yourself to someone or something who will never have enough then I agree, you'll get sucked in.

Reform appears to be on track for a major win in the next UK election. How will they address the problem of the UK nanny state?

Looking at the USA: the federal policies are currently as anti-immigrant as possible, and in the US states which support those policies the most, age verification has been passed into law.

I fail to see how being anti-immigration, no matter one's opinion on that matter, resolves the basic issue of a nanny state.

I joke, but I think it’s depicting relative proportions of how many people who were “interested in” Gemini are now “interested in” other things and how different subgroups’ “interested in” thing changed over time. So there was a sizable group that became interested in Tailwind at one point

I guess they're covering every segment.

I've not seen any of those higher end models myself, I'd be curious to know what kind of numbers they're selling in here versus, let's say, European high-end EVs.

I didn't mention Polestar myself either as I'm undecided whether they fit into the "Chinese brands" category; they are Chinese now but I wonder what if any influence Volvo still has on them and if so, what effect that might have on their quality and reliability; perhaps it's "none", but I see Polestar as a brand that would be a more likely purchase because of its Volvo heritage.

I've never seen a Zeekr or Xiaomi vehicle here in the UK, not sure if they're on sale here (yet).

Fluff mainly built around trying to push something which has rich elites (regardless of political bent) believing that school shouldn't spend time teaching the skills they don't use because they don't use them. (And by don't use i mean society applauds them for not using rather than they're incapable)

This schooling by design locks out the possibility of world leading medicians, scientists, mathematicians and economists if it ignores learn by rote. Just because repetition is boring doesn't mean it's not essential, and frankly before the age of 18 is when you're most susceptible to getting benefit from that learning.

Same goes for a lot of the new age and home schooling. It's not that that these models can't work. But they're normally fighting against an education system which has been refined for almost 100+ years in the developed world. Instead, the good ones embrace and extend without extinguishing. Just because it has it's faults (it does) doesn't mean you throw out the baby with the bath water.

Then again kids going to such a school are going to be wealthy and connected which in certain strata in society matters more than efficacy or meritocracy (regardless of what is preached).

This nonsense that ML(AI) will be the ultimate recall always is the worst of fluff. It's right behind "terminator". ML systems are at best a great tool on hand for experts because query and verify to them is faster than lookup, then reference and then query is to do manually. That's the point. And no, not a single ML system has proven reliable outside of a lab context in raw isolated offline fact verification...

Haha, yes, autovectorization is so much in the way sometimes. I have a bunch of hard-coded AVX2/AVX512 intrinsics lying around since the compiler can do it fine on Compiler Explorer but not in context. Still, having a stall on a single 512-bit add like that suggests something very odd in the µarch. Perhaps something like “we're all out of physical registers and we're going into some kind of panic mode” that is avoided by inserting the assert() branches and slowing things down. No idea, I'm not a Zen microarchitecture expert.

Edit: I ran the code on an Intel CPU (Kaby Lake, on my laptop) and there's no slowdown when removing the assert(). So it really seems to be something Zen-specific and weird.
Show HN: Gogg – A GOG game downloader written in Go

Hey HN,

I made an open-source tool in Go, named gogg, to download and back up your GOG.com game library.

It's cross-platform and has features like:

- A scriptable CLI and easy-to use GUI

- Multi-threaded and resumable downloads

- Filters for platform, language, DLCs, etc.

- File verification with hashes and total size calculation

"Just walked near the capital. Didn't break in, attack cops, destroy property. "

I don't think you followed the story or cared because it involved people you didn't like. Yes, there were people that destroyed property. Others didn't even know what was going on at the time and were let into the capital building by police officers and were arrested anyway.

The Democrats in the UK were arresting people for just voicing their opinions over the last year. No outrage. Now that the UK is trying to prevent children from getting hurt online: total outrage.

It always seems to involve children..

I don't think they are trying to preserve privacy between you and the identity provider you are logging in with and the website you are logging into. (At least not now. There's talk about some of this with IDP delegation, I think. Here's more on that: https://github.com/w3c-fedid/delegation )

I don't know if this is a big factor, but, kids for the last 10 years have had access to really good training techniques for free via youtube. Every kid has the opportunity to use the same training techniques as the professionals.

By the time they get serious and have access to professional coaches, they've had maybe 5 years of good quality training.

As well as bikes have improved a lot. Clothes have improved a bit. But the biggest factor of all are the drugs. I mean I don't know. I'm just cynical.

I think it's a level playing field, though. I think it was a level playing field during the armstrong era.

Maybe armstrong had better drugs, better doctors, but it's not like the other riders were clean.

> Syntax is probably one of the single most important things in any language. It matters for writing, but especially for reading.

That appears to be your position (and maybe even that of a majority of developers), but it apparently isn't the position of the Pony developers. If you have a language in which you can mathematically reason about code (which Pony claims very prominently), then surface concerns such as syntax seem to matter less.

It's a different design goal and it feels like many people in the comments here don't appreciate that.

Pornography addiction doesn't exist. No major medical body in the world considers it an actual condition. Studies show that self-reported pornography addicts consume the same amount of pornography as non-addicts, but have much higher rates of religiosity and conservative sexual norms. Pornography "addiction" is a moral panic narrative, not a medical reality.

I agree that children should not have access to sexually explicit material and that it can warp their relationships to sex. I also agree that some people have unhealthy relationships to pornography; there are plenty of psychological and psychiatric factors that lead people to engage in disordered sexual behaviours.

But people NEED to stop bringing medical pseudoscience into these discussions. Statements like "[children] form lifelong addictions that stunt their emotional and developmental growth at the click of one button" are neither true nor useful.
Ask HN: Where do you host your vibe-coded apps?
by anoojb | 2025-07-29 16:27:04+00:00
Deploying the marginal vibe-coded prototype feels like more work than actually authoring the app these days.

My constraints are that I'm cheap and like things to be dead simple. So right now I'm usually deploying a set of static files with sqlite+litestream.

This seems relatively fragile and prone to breaking changes and data loss. Are there alternatives I should consider that are relatively cheap/easy to manage for an individual developer?

I posted this comment in 2013 [1] and I stand by it 12 years later:

Cucumber tries to solve the problem of turning customer requirements into 'real code'. In exchange for that worthwhile benefit, it asks you to implement the most terrible, reg-ex based spaghetti code imaginable.

The problem is that it doesn't solve the original problem AT ALL. And then you are left with terrible reg-ex driven spaghetti code. Like the Jamie Zawinski saying, "now you have two problems".

The lesson here is that software development processes have to pass the 'human nature' test.

The software industry has largely abandoned waterfall development because it just doesn't work well in practice. It doesn't work because people don't know perfectly what they want before they build it. Agile processes usually are much more efficient because they are more closely aligned to how humans solve problems in the real world.

Cucumber suffers from the same issue of being disconnected with reality. In theory, you can find a customer who can give you perfectly written use cases and you can cut-and-paste those into your cukes. In practice, that never, ever works. So let's all stop wasting our time pretending it was a good idea now that it has been shown to not work.

I wonder what the (supposed) anti-censorship people that supported things like eSNI and DoH think about this. They took away our ability to filter our own networks, so now we can't even argue that filtering and monitoring is something that should be done on the client side (per network).

Sometimes I feel like both sides are actually just one side playing the long game. IMO the goal is to get verified digital IDs in use everywhere they can so they can lock down the internet to have absolute control. We'll end up paying inflated subscriptions for everything and watching all the ads.

These are the kinds of regulations that are deigned for incumbents because it becomes impossible for new market entrants to satisfy the requirements. I wouldn't be surprised if big tech companies are silently lobbying for this kind of stuff behind closed doors.

i don't think equality was ever the goal. The goal was just to let more people play sports, have fun, and have a realistic chance of winning within their chosen division.

If a professional baseball player wanted to play in a little league tournament they'd do very very well, but it'd be unfair to a bunch of 7-12 year olds, so we don't allow that and the sport is "separate", but when a 9 year old kid wins the Little League World Series, while that's very exciting for the players, we still don't treat that win as being equal to winning the actual World Series.

Winning the actual World Series is a much bigger deal. Nobody treats them as being equal, but being inherently unequal doesn't mean that it's wrong. The Little League World Series can just be its own thing, because what actually matters is that the kids are having fun playing the sport they love and don't have to worry that some 30 year old with a batting average of .340 is going to ruin their good time.

There are times when "separate is inherently unequal" is actually the most fair.
Show HN: CineWan – video generation platform powered by Wan2.2 AI model
by howardV | 2025-07-29 16:28:02+00:00
I've been working on CineWan, an AI video generation platform that leverages the new Wan2.2 models with Mixture-of-Experts (MoE) architecture. Technical highlights: • MoE architecture separates denoising across timesteps with specialized expert models • Dynamic routing system selects experts based on content complexity • Generates up to 720p, 121-frame videos from text or images • Built on Next.js 15 with edge runtime for <50ms global response times • Smart cost optimization: Cloudflare R2 storage with 3-day auto-expiration • Real-time progress streaming with exponential backoff polling The Wan2.2 models were trained on +65% more images and +83% more videos than v2.1, with integrated cinematography principles. We're seeing cinema-grade output quality that rivals much more expensive solutions.

But we know that variable names do not matter whatsoever to a compiler. Now I do agree with you intuitively that LLMs perform better on meaningful variable names, without looking at hard data - but I don't think it has anything to do with "brainpower" - I just think your input data is more likely to resemble training data with meaningful variable names.

Let's skip those places for a moment. What are the signs of apartheid in Israel proper? I don't have access to the sources listed. Just one or two things off the top of your head would be a lot for me.

Percentages don't work like that, either. Since buyers are mostly bound by available monthly budget, raising interest rates increases effective price, which lowers demand at a particular price point which drives total purchase price back down to get the monthly mortgage price closer to affordable.

Obviously, this feedback isn't entirely effective because buyers can simply opt out or delay a purchase but it does have substantial effect.

Thus, increasing interest does not have the full impact as predicted by assuming that purchase price is fixed.

That sounds similar to me like the argument against anti-depressants that it's "not real", and you're not actually better, you're just addressing symptoms, not the cause. But my experience is very clear: that's a huge improvement.

Clearly people have needs, clearly they feel chatbots satisfy those to some degree (otherwise they wouldn't use them). To those people, it's an improvement, I don't see how that's a negative.

In the same ruling, he found that Anthropic’s wholesale downloading and storage of millions of pirated books — via infamous “pirate libraries” like LibGen and PiLiMi — was not covered by fair use at all. In other words: training on lawfully acquired books is one thing, but stockpiling a central library of stolen copies is classic copyright infringement.

I spent a lot of time tryngito figure them out mid carreer before I realized that high priced consultants made a lot of money selling training me on it to management. The same salesmanship worked on me. Perhaps in part because they were also teaching unit testing which did turn out useful - once I got rid of the bad ideas they taught since they didn't know what worked in the real world but had a lot of money to make by sounding confident when asked questions.

I think it works because if you see your memories in the brain as a road, it will make sense. Any memory or association you create between two things builds a tiny little road. Your brain scales that road based on how much you use it. Any time you recall that memory by repetition, the road gets stronger, the stronger it is, the more persistent it stays as memory. If you don't use it at all, then at the end, it will get demolished to free the space (you forget).

That is the mental model I have of it, I don't know how accurate it is though.
