This is the same mental mechanism that makes me hate (pseudoscience) personality tests. Many of my friends that use them fall for similar trap of "labeling" themselves.

When those labels aren't informative or accurate at all, it ends up becoming a chain rather than liberation. "Oh Im MBTI-4acronym, according to that personality test, I'm an introvert so I should skip this public event!".

We are inherently complex and multi-label, even with the worst simplifications. That's confusing and frightening to many, so we seek an "oracle", authority, that can tell us who we are. Problem arise when those are false prophecies.

And they are almost always false. (to varying degrees) Social media mental diagnosis is exactly the same. And crucially they're very wrong over time [1]. So it end up as a shackle to stunt their growth. It completely stops the trail&error process, exposure, and creates a self reinforcing cycle so the label becomes deeply rooted as an identity. There's really no substitute for "trying out yourself to see what works for you, and make sure your trials are set up so you can learn something from it" when it comes to self discovery.

I wish psychology was a bit more scrutinized field. The amount of popscience garbage they give out, and how many people use these model to judge and limit themselves in their life is so sad to see. Probably one of the primary reasons I would keep social media far away from kids (if I had any).

"Disproportionately impacts" means that the burden of pollution isn't randomly distributed - it's systematically concentrated in specific communities. In this case: predominantly Black neighborhoods in South Memphis already have asthma rates and cancer risks 4x the national average (per the article), and xAI added unpermitted turbines to that existing burden.

You're absolutely right that most hazards affect poor communities more. That's not a coincidence - it's the predictable result of power dynamics in zoning and enforcement decisions.

Your comment reads a bit like "water is wet, why mention it?" But most people living in clean-air zip codes have no idea their comfort of living depends on someone else's respiratory disease. They assume industrial siting is purely based on logistics or economics, not on which communities lack the political capital to fight back.

The whole point is that zoning decisions, permit enforcement, and industrial siting aren't random acts of nature. Rich neighborhoods get golf courses and poor neighborhoods get data centers with unpermitted turbines. That's not gravity - it's policy. Documenting these patterns isn't stating the obvious, it's the first step toward accountability. Because "that's just how things are" is exactly what those benefiting from the status quo want everyone to believe.

Interesting, I was sure they would all have some kind of wifi these days. I think my parents have the Bosch, it's pretty good. I just find it weird that they have two input methods, the turning wheel and tip touch buttons that don't really respond well.

Mind you, I have 'regular' buttons that don't respond well either.

I did not expect 2025 to be the year K-pop finally hooked me.

Completely see why Demon Hunters has taken the US charts.

I watched it for the animation (same Sony Pictures Animation studio as the Spider-Verse movies). It's breathtaking to watch if you're an animation junkie, but I was unexpectedly blown away by the soundtrack.

Every song's beautifully written and performed. It's catchy in a way that Disney stuff used to be. Yes, it's cheesy boy-vs-girl finding-yourself ultra-produced pop — but it's also just uplifting to watch. And it's full of cheek, personality, and nice production touches (like the triplet can-pull fills on Soda Pop).

The blending of English and Korean is a nice touch too, even more noticeable in the lyric videos that Sony Pictures has put out than the movie itself, which have each blown through 15-30 million views over the weekend, most of that from me.

Well said.

And what I’ve found is your team knows who is and who is not performing. And if you fail to do something about the low performer under the guise of being a nice person (or hoping they’ll eventually figure it out), your team will lose respect for you.

A team of high performers does not want to have to carry along a straggler, no matter how nice they are.

In my experience, I wish I’d made those hard decisions sooner in hindsight, rather than hoping they’d get where I wanted them to be.

It can create some weird unintended consequences though. Like if people know you regularly manage out low performers, they might be risk averse to try something difficult for fear of failing and losing their job. They need to be able to see exactly why someone didn’t make the cut.

It’s a difficult line, especially when complicated by blunt corporate incentives like stack ranking and PIP’ing the bottom 10%, etc where it can be less than clear sometimes.

It’s more clones of 200-400-800 dollar stuff for 40-100 dollars. They’re in many cases definitely made by a different place than the oem because they based their design on public stuff online image and specs wise then made their own tweeks. Usually slightly different geometry, often one of d2, 8cr, 9cr, vg10, 154cm or m390, with first 5 usually being honest labels. (The vendors say mark foo when it’s just visual blade print label. ). There’s def some instances where the clones also actually have design tweeks that make them competitive or better than the originals in fit and finish.

Afiact, the Main good vendors are green thorn, lemifshe and jufule currently. But if you ask the vendors detailed questions before spending money they seem pretty honest.

As for a blade steel breaking, that should be less likely with Chinese blade heat treats since they all tends to err on the side of undershooting hardness and cap out at 60hrc. So in many cases way less brittle than a western heat treat if it’s the same steel

I have gotten much more value out of AI tools by focusing on the process and not the product. By this I mean that I treat it as a loosely-defined brainstorming tool that expands my “zone of knowledge”, and not as a way to create some particular thing.

In this way, I am infinitely more tolerant of minor problems in the output, because I’m not using the tool to create a specific output, I’m using it to enhance the thing I’m making myself.

To be more concrete: let’s say I’m writing a book about a novel philosophical concept. I don’t use the AI to actually write the book itself, but to research thinkers/works that are similar, critique my arguments, make suggestions on topics to cover, etc. It functions more as a researcher and editor, not a writer – and in that sense it is extremely useful.

Presumably the value in knowing "you need to sort a string in place and then discuss how a random forest gets trained" is that it impacts your answers - for instance, by allowing you to look this up before the interview while appearing to the interviewers to he operating unfer the dame conditions as the other candidates, who did not know to. Your performance then appears as a signal of broader inwoledge and capability than you possess - you have, as is the entire point here and which I should not need to spell out, gained an advantage over other candidates by virtue of the information which was intentionally leaked.

If the point of the interview were "answer those questions AND know enough to answer the follow up questions" _once told what to expect and prep_, they’d be sharing those questions with all candidates. If you feel that saying to the interviewers "by the way, I did know this because [X] told me they’d be here" wouldn’t impact outcomes, then great. If you feel you’d need to hide that, then you’re aware this involves dishonesty - and if you still struggle to see how that’s unethical, lets just make sure we never need to work together.

Deno can restrict access to filesystem files or directories, and to particular network domains, see docs for examples. https://docs.deno.com/runtime/fundamentals/security/#file-sy...

However in general I don't think Deno's permission system is all that amazing, and I am annoyed that people call it "capability-based" sometimes (I don't know if this came from the Deno team ever or just misinformed third parties).

I do like that "deno run https://example.com/arbitrary.js" has a minimum level of security by default, and I can e.g. restrict it to read and write my current working dir. It's just less helpful for combining components of varying trust levels into a single application.

Hey HN,

I built BlazeURL – a smart link shortener that does more than just shorten URLs. It sends instant alerts when someone clicks your link, so you’re never in the dark about engagement. Great for outreach, testing, or just satisfying your curiosity.

Features:

- Real-time click notifications - Basic link analytics - REST API & MCP integration - Simple UI, privacy-first

It’s lightweight and fast. Ideal for indie hackers, marketers, and devs who want tighter feedback loops.

Would love your feedback, feature requests, or ideas for use cases. Thanks!

I think they are trying to do something like this(1) by long term providing a "business suite", i.e. something comparable to g suite or microsoft 360.

For a lot of the things which work well with current AI technology it's supper convenient to have access to all your customer private data (even if you don't train on them, but e.g. stuff like RAG systems for information retrieval are one of the things which already with the current state of LLMs work quite well). This also allows you to compensate hallucinations, non understanding of LLMs and similar by providing (working) links (or inclusions of snippets of) sources where you have the information from and by having all relevant information in the context window of the LLM instead of it's "learned" data from training you in general get better results. I mean RAG systems already did work well without LLMs to be used in some information retrieval products.

And the thing is if your user has to manually upload all potentially relevant business documents you can't really make it work well, but what if they anyway upload all of them to your company because they use your companies file sharing/drive solution?

And lets not even consider the benefits you could get from a cheaper plan where you are allowed to train on the companies data after anonymizing (like for micro companies, too many people thing "they have nothing to hide" and it's anonymized so okay right? (no)). Or you going rogue and just steal trade secrets to then breach into other markets it's not like some bigger SF companies had been found to do exactly that (I think it was amazon/amazon basics).

(1:) Through in that case you still have employees until you AI becomes good enough to write all you code, instead of "just" being a tool for developers to work faster ;)

FWIW, the book was written in 1972.

I mean "there were some people", not all people - Thomas, in the quote, came from Paris and spoke French. He did not learn a regional language.

I don't mean 'many regions' because the only example I had was one region. The fact that there was at least one region where local French people, in a region which had been part of France seemingly since at least the Middle Ages, did not speak French as their mother tongue, astonished me.

FWIW, the French Wikipedia page says:

> Ainsi Malevil serait partiellement inspiré du site de Commarques (sa grotte, son abri troglodyte et son château)[2], tandis que le village de la Roque serait partiellement inspiré de la Roque Saint-Christophe, forteresse troglodyte voisine du château de Commarque. ...

and the location,

> La vallée des Rhunes : inspirée de la vallée des Beunes, et plus précisément la grande Beune.

so the author's fictional location was supposed to suggest the department of Dordogne in south west France.

https://en.wikipedia.org/wiki/Limousin_dialect tells me

> Limousin ... is a dialect of the Occitan language, spoken in the three departments of Limousin, parts of Charente and the Dordogne in the southwest of France. ... Limousin is used primarily by people over age 50 in rural communities. All speakers speak French as a first or second language. Due to the French single language policy, it is not recognised by the government and therefore considered endangered by the linguistic community.

Those people over age of 50 would likely have been children in a book written 53 years ago, with Limousin as a much more common language amongst the local adults.

> Why fund metal and smart Wi-Fi appliances when you can empower someone’s life?

Because it's illegal to pay so little, and nobody would do it for that price anyway, except for maybe your own children, who do it for that price plus the negative incidence of an asswhooping. If it were affordable for common people to have servants or slaves, they totally would. Machinery priced slaves out of existence. The next frontier is for value-added centralized industrial manufacturing to be priced out by distributed manufacturing and recycling, not a return to the days of domestic servitude.
Show HN: I built PrompTessor – a tool to help people write better AI prompts
by rizkimurtadha | 2025-07-07 11:41:43+00:00
After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live.

As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor.

This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And even a step-by-step guide on how to improve it

PrompTessor evaluates your input across six dimensions: Clarity, Specificity, Context, Goal, Structure, and Constraints — helping you communicate more effectively with any LLM.

It’s free to try, and my main goal right now is to gather as much real-world feedback as possible. As a solo founder, honest reactions and suggestions from this community would mean the world to me.

Try it here: https://promptessor.com

Every piece of feedback is incredibly valuable, and will help me shape PrompTessor into something truly useful.

Thanks for reading! Happy to answer any questions in the comments.

If you wanted to be legit with 0 chance of going to court, you would contact publisher and ask to pay a license to get access to their catalog for training, and negotiate from that point.

This is what every company using media are doing (think Spotify, Netflix, but also journal, ad agency, ...). I don't know why people in HN are giving a pass to AI company for this kind of behavior.

It's a large power plant (400+ MW and rising), rapidly assembled from small, modular components. That's a remarkable thing from any point of view.

The other threads on this topic (powering AI hyperscalers) are usually about nuclear fission, which most of the large players are investing in. Those power plants often take 10+ years to build. One could imagine small reactor modules akin to these 16 MW shipping containers, built in factories and shipped on demand like these, to be assembled into a full power plant in weeks. If someone were to get that business model working, they'd dominate the industry. (Just how big of a premium did xAI pay their vendor, to have all this shipped halfway around the world on a priority schedule?)

Every feature that is added, even if you don't use them, is another piece of tech that can break and potentially be non-serviceable. I've several times now had to repair or replace major appliances in the first 3-5 years of use because of logic boards and such that were unrelated to the core functionality of the appliances.

Granted, not everyone wants or cares to minimize waste when it comes to objects of convenience, but plenty of folks want the option... and yes, I do realize I sound like "your father who bought fancy cars with manual windows because it's one less thing that can break." :) My own father was that kind of person.

Seems like, You've got it backwards — and that makes it so much worse. ^_^

I ported from ABAP to Z80. Modern enterprise SAP system → 1976 processor. The Z80 version is almost as fast as the "enterprise-grade" ABAP original. On my 7MHz ZX Spectrum clone, it's neck-and-neck. On the Agon Light 2, it'll probably win. Think about that: 45-year-old hardware competing with modern SAP infrastructure on computational tasks. This isn't "old tricks don't work on new hardware." This is "new software is so bloated that Paleolithic hardware can keep up." (but even this is nonsense - ABAP is not designed for this task =)

The story has no moral, it is just for fun.

There are multiple NOx sources during combustion.

Fuel NOx is only one of them, which you quite rightly point out is not dominant in methane combustion due to the rarity of nitrogen in the fuel.

The dominant source in methane combustion is thermal NOx, which forms due to the extreme temperature of the combustion, causing atmospheric nitrogen to decompose and react with atmospheric oxygen.

Meiotic drive is selection.

> it isn't Darwinian selection, because it can favour transmission of genes which are not conducive to survival

This is the one thing that Darwin got wrong: he thought that the unit of selection was the organism, but it's not. The unit of selection is the gene. Richard Dawkins is the one who figured this out. Meiotic drive is not Darinian selection, but it is selection. But Darwin could not possibly have known this because genes were unknown at the time.

actual title:

"Anthropic cut up millions of used books to train Claude — and downloaded over 7 million pirated ones too, a judge said."

A not-so-subtle difference.

That said, in a sane world, they shouldn't have needed to cut up all those used books yet again when there's obviously already an existing file that does all the work.

In my experience Uber Eats search may as well not exist.

It is so fundamentally broken that it doesn't actually deliver what customers want.

It doesn't matter what you search for, it's going to mostly deliver bad results. Part of that is going to be bad and integration, but a lot of it isn't.

Search for Pizza, will give you stores that don't sell pizzas. And not even after all the pizza stores.

Search for chicken and I get a vegan only store that doesn't even have any meat terms on any menu item, and never did.

It's a complete failure as far as I am concerned.

That it served a billion queries matters not if they are bad results.

Is your benchmark trustworthy?

I see strange discrepancy: my "old" i7-12700K vs i7-13700K:

Games: 170 vs 270 Software: 271 vs 1875 (!!!)

I can believe into 170 vs 270 (though, these two CPUs are not so different!) but 7x difference in software!? Is it believable?

It doesn’t need to be entirely willpower. Opioid dependency can be dealt with by doing what they would do in rehab: slowly taper down the daily dose over many weeks.

Of course, that only works if you have access to a standardized, regulated supply of opioids. You can’t do it with street drugs of unknown purity.

Going cold turkey off potent opioids is a recipe for relapse, or at worst, death.

Still, the likelihood of dying from withdrawal is much, much lower than with benzos or alcohol: both of those can cause seizures in withdrawal.

no it doesn't has to it just has to be "general"

as in it can learn by itself to solve any kind of generic task it can practically interface it (at lest which isn't way to complicated).

to some degree LLMs can do so theoretically but

- learning (i.e. training them) is way to slow and costly

- domain adoption (later learning) often has a ton of unintended side effects (like forgetting a bunch of important previously learned things)

- it can't really learn by itself in a interactive manner

- "learning" by e.g. retrieving data from knowledge data base and including it into answers (e.g. RAG) isn't really learning but just information retrieval, also it has issues with context windows and planing

I could imagine OpenAI putting together multiple LLMs + RAG + planing systems etc. to create something which technically could be named AGI but which isn't really the break through people associate with AGI in the not too distant future.

That will be sad, although there will still be plenty of great people who will write books anyway.

When it comes to a lot of these teachers, I'll say, copyright work hand in hand with college and school course book mandates. I've seen plenty of teachers making crazy money off students' backs due to these mandates.

A lot of the content taught in undergrad and school hasn't changed in decades or even centuries. I think we have all the books we'll ever need in certain subjects already, but copyright keeps enriching people who write new versions of these.

We have FAANG to thank for this. They pioneer counterproductive interview questions (remember puzzles?), and the industry just copies these trends, like zombies.

Then what happens is these Leetcode heroes, never having built anything from scratch in their lives, create a hazing ritual for new candidates.

What is the point of, say, a system design interview asking to design a planet-scale system when most people never came close to one or, again, never built one because they are just out of school?

And, yes, I know - "how would you interview a recent student?".

Fine, I was a student in 2004, so why are we having the same goddamned test?

BG3 has extensive modding support to the point where people released mods that turn it from a "classical" rpg to a roguelike.

BG3 has public lobbies, private lobbies, and *all* games are hosted locally on the hoster's computer, can be played through LAN without internet. It also has split screen coop.

Nothing you said about BG3 has an ounce of truth to it, and it is one of the most consumer friendly games in a sea of anticonsumer garbage. Are you trying to discredit Larian for some reason?
