> It recommends class 1 e-bikes so you still have to pedal (no throttle).

Where I live, the trend is either to buy an electric motorcycle and ride it around as if it was a bike (on sidewalks, bike trails, crosswalks) or to buy a hackable e-bike and unlock the power limit and add a throttle.

The interest in real class 1 e-bikes seems minimal. The hacked e-bike and electric motorcycle people are making bike paths and trails much more dangerous for everyone.

Even the normal e-bike people have seemingly forgotten that there are rules. I had to jump out of the way of a middle aged woman who blew through a stop sign on her e-bike and turned right straight into us pedestrians. It’s common to see e-bike riders jumping between the sidewalk, road, and crosswalks as convenient and blowing through the four way stop by my house.

This is literally the argument keto, carnivore, and caveman diet people make. "I feel like this is how we ate 10,000 years ago, so it must be natural and therefore good!"

We also didn't get vaccines for most of history. That doesn't mean remaining unvaccinated is good.

For the record, keto works for me (including bloodwork to prove it) but is unsustainable. My mind is never sufficient compared to when I'm eating normally. It's observable in my work and parenting. Although, last time I was on keto, my cholesterol was through the roof. I went off keto and three months later numbers were back to normal. And I wasn't consuming a shitton of meat and butter or anything. I was pretty close to exactly the right numbers for optimal health. Just...something made the numbers terrible and I've no idea why. Did a re-test to confirm. Same awful cholesterol.

On IF I actually got fatter. Numbers worse. Less healthy. Couldn't exercise as vigorously.

For me, calorie counting works. It's also not sustainable, because with kids you get in a rush and if you have a normal social life you eat at places you can't calorie count.

To stay healthy I just try as hard as I can and exercise (distance running, weightlifting, tennis when I can, which is pretty rare with three young children).

> But they are never based upon any objective criteria, and are never (nor ever were intended to be) reproducible in any scientific fashion.

This is also why review aggregators exist: if I'm just getting into a thing, such as watching movies or buying appliances, I probably need a general sense of how people collectively feel about a thing. But if I'm keenly aware of my preferences, it helps me to find reviewers who align with how I think. People routinely seek out specific reviewers or specific publications for this reason.

For instance, someone reading this review might conclude "I really appreciate that ease of use is a topic that's front of mind with this reviewer." Another reviewer's focus might be customizability, and they might recommend AirGradient. And that reviewer's audience follows that person likely because those concerns are front of mind.

...to be honest, if AirGradient had responded more along those lines ("we prioritized X and Y. We understand if this isn't the best fit for customers looking for Z, but we're working on it"), it would've felt more empathetic and less combative to me.

> > they show that you can use SAT to solve Sudoku

> Wait, did you mess up the direction here too, or am I confused? If you reduce problem A to B, then it means B is at least as hard as A, because solving it would solve A.

Using SAT to solve Sudoku is a reduction of Sudoku to SAT. The order of the problems names switches depending on how you write it.

On the other hand, Swift is a public figure, and with that comes parody -- I'd be more sympathetic if it was a private individual, but existing harassment and defamation laws could handle that most likely. Fake (insert celebrity) Photoshops have been with us since the 90s.

>When I saw the “spicy” option I thought it was about being sassy or playfully mean instead of the sanitized LLM voice.

Yeah, I thought it would just not have NSFW restrictions, I find the idea someone's like "What's the value of twenty dollars from 1920 adjusted for inflation" and suddenly you're got the guy from the Gangam Style video screaming into a butt but it's the Pope's face or something.

FeliCa Networks support is the direct result of the fact that mobile transit and mobile payments use in Japan predates the iPhone. Mobile Suica and Osaifu-Keitai already existed, and Apple needed to compete. It started with Japanese SKU iPhones but expanded globally.

Even now in Japan, mobile payments are anything but a monopoly. When Apple is forced to compete, they do things like add Suica with Express Transit. PayPay, a made-in-Japan QR code payments app is more prevalent than credit card payments here.

Apple having such a dominant hold of market share in the smartphone space gave a lot of leverage when negotiating royalties with Sony who makes the felica stuff. From what I heard it was basically just gifted to them, because if Apple says no we wont support it, then you lose a huge amount of users. Whereas with other manufacturers they pay on a per device basis tracked by the underlying osaifu-keitai stuff. If you are rooted though it is usually just 1 flag or something you need to change. Been using my US Pixel 6 for years daily on my commutes.

Every time someone criticizes reddit I automatically assume that they have brain damage.

When I go to reddit, I see posts about astrophotography, vintage computers, ham radio, classic cars, typewriters, film photography, sculpture, gardening, woodworking, firefighting, archery, fencing, outer space, watches, cutaway drawings, the Sega Saturn, and more topics I'm interested in.

When they go to reddit they see stuff they don't like, and people arguing about it.

I just want to shout "yes, you do, because your brain is damaged and you asked it to show those things to you".

It's the same with all social media. When I go to instagram I see people I know personally and have been in the same room with doing things I am interested in. I don't see any rage, titillation, celebrities, or gossip. Just my friends and acquaintances being friendly. (It IS annoying that I keep having to turn off suggested posts)

Even when I click on the magnifying glass, which is where people say Instagram shows them titillating things in order to get them hooked, I see scuba diving, aviation, vintage Macs, watches, and astronomy.

What is going on? Do I have a "only show this guy nice stuff he's interested in" cookie following me around the internet?

And YouTube. People will complain about YouTube showing them shit. When I go to YouTube.com, right now, I just opened it in another tab, the top six videos are: Dutch firefighters battling a stable fire, a homelabber messing around with vintage linksys equipment, a history of the development of nuclear weapons, a review of a handheld video game emulator, a guy with a VAX setup in his basement working on restoring those machines, and a video on new theories about how the moon was formed.

The next six are also laser-focused on my interests including a two hour video about various motifs found in Indo-European mythology and their origins which I am totally going to listen to in the background while at work.

I did nothing, NOTHING, except subscribe to/follow things I like and people I know, and it's great.

When people log into reddit and see people arguing about bullshit, instagram and see models bouncing their tits, and YouTube and see garbage, the only logical conclusion I can reach is that their brains are damaged and they set up the systems to show them these things then decided to complain about it as some kind of hobby or something.

If anything, HN is the worst of them all because I can't tell it "show me more 'floppy disk raid array' and less 'crypto and AI bullshit'".

Haven't coffee shops since the beginning two hundred years ago been places where people might hang out for a long time without spending much? In the 1800s and beginning of the 1900s? It shouldn't be a problem that people spend time there without spending money, as long as there's plenty of empty tables available, as I see it. And most laptop patrons are conscious to spend some money and not overstay their welcome.

The idea pitched in the article would probably only work with Dutch or central Europeans in general, who unfortunately lack a lot in culture after WWII. Europeans love rules and regulations, and will follow them and take any opportunity to abuse things when there's no explicit rule. Such as overstaying your welcome with your laptop in a café. If this idea with a minimum spend would be pitched in a more mature culture, people would just scoff at it and not visit such a café.

Don't forget the thousands of civilians that committed suicide. There are accounts of soldier interpreters pleading with civilians through loudspeakers on their ship to just surrender and be taken care of, while they jumped from cliffs into the sea. Every option (invasion, mass starvation via blockade, atomic bombing) was a horrific nightmare of death for the Japanese.

Over a decade ago, it was my dream job to get a job at one specific FAANG company that is widely known to use a project I've contributed to.

I'm a developer with a project they use, so, I thought, for sure someone would review my resume after applying on their website. Nope.

After being ignored for a while, even having to get a Master's degree because no offers after a Bachelor's, I finally emailed a Director, who was previously a fellow committer at the project. People under him were not hiring at the time, but a recruiter from a different group has contacted me shortly, and I've had a 2-day flyout onsite arranged for two different positions, and had offers to join either one.

More of a question of /will/ Mojo eventually be entirely open source, chunks of it already are. The intent from Modular is eventually it will be, just not everything all at once and not whilst they're internally doing loads of dev for their own commercial entity. Which seems fair enough to me. Importantly they have open sourced lots of the stdlib which is probably what anyone external would contribute to or want to change anyway? https://www.modular.com/blog/the-next-big-step-in-mojo-open-...

> Proton's leadership supported Trump and the GOP

... this again? Come on.

The CEO once expressed support for Gail Slater as head of antitrust and subsequently criticized lack of effective work towards tech regulation on the Democratic side in the same social media thread.

Calling that support for either Trump or the entire GOP is a massive stretch, and throwing the claim out without context borders on disinformation.

I agree totally. My only problem is local models running on my old macMini run very much slower than that for example Gemini-2.5-flash. I have my Emacs setup so I can switch between a local model and one of the much faster commercial models.

Someone else responded to you about working for a financial organization and not using public APIs - another great use case.

> I'm sure they'll make an absolute ton of money from the male loneliness epidemic.

They and others, there's probably dozens of projects popping up to create multimodal companion AIs. character.ai specializes in fictional or custom characters, Discord has some bots that allow for giving them a personality of sorts, Facebook is pushing hard for it, even making the AI bots message you instead of only replying, etc.

It's happening already, and if xAI doesn't join in they may lose a possible market opportunity, depending on whether 'companion' AI sticks.

I'm starting to feel kinda old and out of the loop. Could someone please explain the conversational style of this post?

It begins with a prompt directed at Gemini, followed by what appears to be an AI-generated response. Are these actual AI responses or is the developer writing their parting message in a whimsical way? I'm genuinely confused. Help much appreciated!
Show HN: Aura – Like robots.txt, but for AI actions
by OsmanDKitay | 2025-08-06 13:37:47+00:00
Hi,

I've been watching the rise of AI agents with a mix of excitement and dread. We're building incredible tools that can browse the web, but we're forcing them to navigate a world built for human eyes. They scrape screens and parse fragile DOMs.

We're trying to tame them to act like humans. I believe this is fundamentally wrong. The goal isn't to make AI operate at a human level, but to unlock its super-human potential.

The current path is dangerous. When agents from OpenAI, Google, and others start browsing at scale and speed, concepts like UI/UX will lose meaning for them. The entire model of the web is threatened. Website owners are losing control over how their sites are used, and no one is offering a real solution. The W3C is thinking about it. I decided to build it.

That's why I created AURA (Agent-Usable Resource Assertion).

It's an open protocol with a simple, powerful idea: let website owners declare what an AI can and cannot do. Instead of letting an agent guess, the site provides a simple aura.json manifest.

This gives control back to the site owner. It's a shift from letting AIs scrape data to being granted capabilities. We get to define the rules of engagement. This allows us to increase what AIs can do, not by letting them run wild, but by giving them clear, structured paths to follow.

A confession: I'm not a hardcore programmer; I consider myself more of a systems thinker. I actually used AI extensively to help me write the reference implementation for AURA. It felt fitting to use the tool to build its own guardrails.

The core of the protocol, a reference server, and a client are all open source on GitHub. You can see it work in 5 minutes:

Clone & Install: git clone https://github.com/osmandkitay/aura.git && cd aura && pnpm install

Run the Server: pnpm --filter aura-reference-server dev

Run the Agent: (in a new terminal) pnpm --filter aura-reference-client agent -- http://localhost:3000 "list all the blog posts"

You'll see the agent execute the task directly, no scraping or DOM parsing involved.

The GitHub repo is here: https://github.com/osmandkitay/aura

I don't know if AURA will become the standard, but I believe it's my duty to raise this issue and start the conversation. This is a foundational problem for the future of the web. It needs to be a community effort.

The project is MIT licensed. I'm here all day to answer questions and listen to your feedback—especially the critical kind. Let's discuss it.

I tried these models half-sceptically.

I ended up blown away. via Cerebras/Groq, you're looking at around 1000 tok/sec for the 120B model. For gentic code generation, I found the abilities to exceed gpt-4.1. Tool calling was surprisingly good, albeit not as good as Qwen3 Coder for me.

It's a very capable model, and a very good release. The high throughput is a game changer.

Before the "fat bike" phenomena the same demographic used to ride around in "snorfiets" scooters which were theoretically limited to 25 km/h, but pretty much everyone modified for speeds of up to 50 km/h.

But somehow the Dutch have this collective amnesia on the topic, and today nobody remembers how the "snorfiets" problem of 10-15 years ago has pretty much disappeared, to be replaced by a quieter and safer mode of transport (even ilegally modified E-Bikes usually fall far short of modified "snorfiets" speeds).

> [...]appear to be designed without pedaling in mind, > as exerting effort without proper ergonomics would > quickly become uncomfortable and painful.

This is a trend in E-Bike design in general, which makes sense. When they first came out manufacturers were just adding a motor and battery to existing designs.

The "fat bike" design is something that wouldn't work well unassisted, because it trades a severe increase in rolling resistance for better ride comfort.

But as a clean sheet design it makes more sense than the alternative. Why incorporate a complex suspension design (which, to be fair, some of them also have), when you can just have the tire absorb the bumps in the road? The marginal cost in electricity is trivial.

You've messed up the direction here.

Reducing unknown-complexity to NP-complete means you can bound the complexity by above, but not by below. I can reduce binary integer addition to SAT, which means that binary integer addition is no harder than SAT... but we also know by other algorithms that it is in fact easier than SAT.

To bound by below, you have to reduce NP-complete (or NP-hard suffices) to unknown-complexity.

I always wondered if evolution through natural selection has essentially halted for humans for the most part. My thinking is even the previously most likely to die before child bearing has been reversed by modern society. Given that it happens at such a long time scale and modern humans and technology hasn't be around that long in the grand scheme of things it's probably not true, but I always found it interesting...

Interesting choice to be using CPython. Very impressed with the completeness, and in particular the Risk Engine. Not having delved in too deeply yet, it does have the basics, but the markets are very highly regulated, and automated trading is always in the microscope. At Goldman, my team's whole job was to make sure the automated trading desks have all the checks implemented. It's a little spoilsport, but anyone seriously looking to use this, it's not gonna be very plug and play, at least while comlying with the market regulations.

> This type of group riding brings back real-world socialization, which is especially crucial right now.

There are few nations in the world that respect cycling as a mode of transportation enough to legislate that cyclists are permitted to ride two abreast (I am only aware of the Netherlands). Instead, in most nations two cyclists out for a "convivial" trip together are forced to ride single file while two seat wide vehicles operated typically by a single driver in a vehicle wider than two bicycles riding abreast speed merrily by.

Let the teens ride side by side.

I read it. My point isn't that this is bad. My point is that it's a solution that imposes a large enough burden on at least some people that it's not automatically an unambiguous win. For me, it represents a large enough burden that if it were forced on me, I'd just stop using the web sites doing so.

Which, you have to admit, is the most secure option. All security measures represent a tradeoff, and sometimes that tradeoff is not worth it.

Because it seems to be a fundamental property of LLMs that they just make things up all the time. It's better to make the LLM a natural interface to a formal query language which will return hard answers with fidelity from the database.

They need the public to (nominally) assent to it first, otherwise it'd be suicide. They're using the republican playbook: overburden the sector with tasks and regulations while underfunding it, and allow for private competition that is not subject to the same regulatory burden. Then in a decade or so, you can claim that the "free market" works better and the public won't kick up too much of a fuss.

No injury I'm aware of. I've never been a runner, trying to start in my 60's. Starting with c25k plan, so it's mostly walking with short bursts of very slow running. No pain during run, but for a week afterward get pain in left kneecap whenever I go up stairs. Everything I've read about kneecap pain is not good.

Not heel striking. I wear thin shoes with no padding (barefoot style) so I couldn't even if I wanted to.

It could be some kind of form issue, I guess.

It's a mystery.

I haven’t checked on Roblox recently, but afaik it doesn’t really allow complete creative freedom or the ability to have a picture and say “make the world look like this, and make the character textures match the vibe” and have it happen. Don’t they still have a unified world experience or can you really customize things that deeply now?

Can you make a basically indistinguishable copy of other games in Roblox? If so, that’s pretty cool, even without AI integration.

> These are also designed to meet regulations, while also being able to easily be modified to circumvent them, such as removing speed restrictions, and removing the need to pedal itself.

This is the trend near me: Kids buy hackable e-bike, immediately unlock it, and then ride their new electric scooter (motorcycle) around pretending it’s an e-bike.

There’s a separated mixed use bike path parallel to a road on my commute. It’s typical to see e-bike kids driving up it faster than the road traffic on the road, while pedestrians and families jump to the side.

> and often the body's response to calorie restriction is to reduce the amount of energy used.

Presumably the point at which it's VERY difficult to expend more calories than you're consuming is something of an equilibrium point, or healthy weight. I find it hard to believe that if you're still 100 pounds overweight after having lost say 20 pounds that it's nigh-impossible to find more "fat to trim" in the caloric intake, for example.
