Im not the OP and I’m an MR tech.

I rate techs against non-radiology trained physicians in terms of identifying pathology. However techs aren’t anywhere near the ability of a radiologist.

Persuading junior techs not to scan each other and decide the diagnosis is a reoccurring problem, and it comes up too often.

These techs are trained and are good. I have too many stories about things techs have missed which a radiologist has immediately spotted.

Why would you ever want to change the tenant id? Thise are problems amateurs create for themselves that professionals dont care abouz at all.

I agree needing an account to create a tenant is not ideal. But that's nothing more than a minor inconvenience. If these are the big problems you make out with M365, then I think I can just shrug your opinion away.

> "If we don't need performance, we don't need caches" feels like a great broader takeaway here.

I don't think this holds true. Caches are used for reasons other than performance. For example, caches are used in some scenarios for stampede protection to mitigate DoS attacks.

Also, the impact of caches on performance is sometimes negative. With distributed caching, each match and put require a network request. Even when those calls don't leave a data center, they do cost far more than just reading a variable from memory. I already had the displeasure of stumbling upon a few scenarios where cache was prescribed in a cargo cult way and without any data backing up the assertion, and when we took a look at traces it was evident that the bottleneck was actually the cache itself.

You should look up the definitions of the word «violence».

You seem to be using violence figuratively (synonymously with ‘injustice’), but ignoring it’s essential and accurate definition.

Both Britannica, Wikipedia, Wiktionary, and Merriam-Webster dictionaries, as well as the etymology of the word agree that «violence» means the use of «physical force».

I’m glad this kind of work is getting highlighted on HN, but this is an extremely misleading title, to the point of being outright false. As often happens, this appears to be due to PR titles being controlled by non-specialists, not the study authors.

While the work the authors do is important, in no sense does the tool they produced actually run a simulation.

A simulation implies a physical model and usually partial differential equations that are often solved on supercomputers, but here the neural network is rather interpolating some fixed simulation output in a purely data-driven way.

The simulations have not gotten faster due to neural networks, cosmologists have just gotten better at using them. Which is great!

Edit: see the sub-comment in the thread by crazygringo for the lead author’s take

> Just because two apples are both green doesn't mean that they are equal. In fact, if there are two apples, that means they are definitely not equal, otherwise there would be just one green apple.

Well, a green apple had better be equal to itself. So if you've got a green apple and another green apple that isn't equal to the first, you're already in trouble and going to have to resort to hacks like numbering them.

> No, the set is not equal to a set of 3 green apples and 1 red apple, under the assumption that a green apple cannot be a red apple (and vice versa).

What if you want to manipulate it in a context where you only care about the number of apples, not their colour?

It's an interesting move from Cloudflare, and entirely rational from their point of view. They need to deal with a coming tidal wave of agentic bot traffic, and one expedient way to do this is erect a toll booth that forces agents to identify, whitelist, and/or pay for access.

I don't know why people are so afraid of deploying open source software on their own. It literally can do most things that the major platform services can do. With AI assistance, it's not hard to deploy or to scale. When you use a company like CF, you are opening the door to a permanent lock-in, to potential compromise of all your customer data by the government, and to extortion, all of which are avoidable.

I don't understand your comment.

If you're given the requirement of highly available, how do you not end up with at least 3 nodes? I wouldn't consider a single region to be HA but I could see that argument as being paranoid.

A cache is just a store for things that expire after a while that take load of your persistent store. It's inherently eventually consistent and supposed to help you scale reads. Whatever you use for storage is irrelevant to the concept of offloading reads

> That is not even wrong. You are mixing up syntax and semantics, and that is because type theorists don't have a concept of semantics.

Right back at you. I don't have to treat notation as something different from semantics, because I'm working in a theory that can handle both elegantly and consistently. Conventional mathematics struggles to describe mathematics as it is actually performed - working mathematicians rely extensively on "abuse of notation", but set-theoretic metamathematics pretends this is out of scope or safe to ignore.

There is no such thing as intent. That's folk science you're describing.

It isn't just USSR, it is the core Russian principle of "oprichnina" - you can violate any laws, human or God's, as long as you're serving the tzar, Secretary General or President Putin. We start to see a hint of it here with ICE, and i'm sure we'll see a bit more of it with the newly formed Domestic Terrorism Task Force.

> The use case is not representative of a real-life scenario, so the value of the presented results are minimal.

Maybe I'm reading the article wrong, but it is representative of any application that uses a PosgreSQL server for data, correct?

In what way is that not a real-life scenario? I've deployed Single monolith + PostgreSQL to about 8 different clients in the last 2.5 years. It's my largest source of income.

You think it's "infantilising" to call them a different culture?

If any of us software developers tried writing a law, all of the lawmakers and enforcers would laugh at how naive our efforts were — that's not us being infants, that's just a cultural difference (making us naïve about what does and doesn't matter), and the same applies in reverse.

> If they didn't know that this law would compromise security, they wouldn't have gotten carve-outs for their own communications.

It compromises their security even with carveouts for their own communications, because computers aren't smart enough to figure out which communications are theirs, nor whether the "I'm a police officer serving a warrant, pinky swear" notice came from a real officer or just from a hacker serving a million fake demands a second.

Is this still how scripts are written? Feels like not being able to figure out an ending is something that was pretty common up until the 1970s, usually with the script of an otherwise great film just getting weird in the last 15 minutes as a result. I figured this was mostly a typewriter limitation, where editing was a lot more expensive.

For example, 2001's and its star child weirdness, The IPCRESS file, and many others.

Seems more often scripts are written with an ending in mind nowadays, with the weird bandaids ending up in the middle instead.

Maybe a bit OT in an article that's trying to be about AI but...

Nostalgia makes everything look better than it was. The reason the internet worked then was because it excluded most people and the few people that were on it had a lot in common (like being young and early adopters of tech stuff and into a lot of immature crap). Holding up a mirror to myself here.

The point is that this never scaled and it started to break down almost immediately as more people started showing up. The moment Facebook broke for me was when I realized my mother, aunts, distant cousins, etc. were seeing absolutely everything I posted there and would be gossiping about it endlessly. Same with linkedin. Fun informal way to keep track of old colleagues and pimp your CV. But then everybody you ever reported to started showing up, and their secretaries, and that annoying guy that you never liked. And it became a cesspool of marketing drivel, up-beat management cliches, and worse. So, I disengaged there as well.

The old internet was only fun because most of those people weren't there yet. It had nothing to do with the technology. The technology was mostly not that great actually. RSS was a bit of a dumpster fire if you ever had to deal with parsing that. It was all a bit hand wavy. Titles go there but sometimes they go there. Dates might be iso timestamps. Sort of. Maybe. Sometimes. But definitely not always. Nominally XML but not guaranteed to be valid XML.

As a standard, it's pretty crap and hand wavy. But it was simple enough that you could make it work anyway and there was enough RSS out there that it was worth trying to parse and make sense of most of it, deal with the encoding issues, try to normalize the timestamps, etc. And do useful things with it (aggregating, pinging, linking bag, and all the other wonderful stuff people did).

The tech was just a (very limited) enabler. What made it work was the relatively homogeneous groups of people using that stuff.

That can still work. But it's not really technology dependent. Without people you have an empty room. Empty rooms are boring. Solving the empty room problem is the key thing. How do you get the right people to show up?

You can roll your own email if you can get your head around setting up an OpenBSD box and configuring OpenSMTPD and the correct domain DNS records - but the issue will be email deliverability. Gmail etc are going to treat as spam most emails that turn up from a residential or VPS linked IP address.

Personal email servers will communicate with each other happily but you need a middleman one for important recipients if you want to be sure it gets into an inbox.

Hmmmm, it's rare that I'll bite, but in this instance, I just have to

> You need to become more like a "normal person."

Isn't in inherently problematic that there is even a definition of a "normal person"? Who gets to judge this? Why do I have to conform? This immediately creates in-groups and out-groups. We should all know better than to allow this to happen. Classification is fine. Probably even needed to help with inclusion. Restriction based on classification can very quickly become problematic.

> No VPN (unless your ISP is extremely shady, then do use a VPN or change ISP)

That's all ISPs by now. You should never just trust any authority logging what you do. What is fine today might not be fine with tomorrow's government and those logs (as much as some might pretend they are not) are permanent. VPN bans will start to pop up all over the place soon and everyone half-paying attention knows why

> no overly zealous adblock (ublock origin on default settings should be fine)

And what is the definition of overly zealous? Chrome has already dropped support for ublock, more or less. Adblocking is directly hostile to the data-hoovering machine. That should be enough reason to use very restrictive adblocking. I am using every filter list there is with Firefox on Linux. Cloudflare's checks are basically always fine. ReCaptcha, however, is a nightmare.

> no JS blocking / weird privacy extensions / whatever

Well, most of the web doesn't work when blocking JS outright. So I guess we've lost that battle. Though I'd argue that things like reader-mode and the ability to just get text content is pretty important to quite a lot of people still, especially those with disabilities. I don't understand the derogatory tone used when calling privacy extensions weird and the 'whatever' part is just a flippant dismissal of an entire ecosystem of extensions and applications that have a right to exist

> nno PiHole

PiHole is soon going to be the only way to protect yourself, considering what Google is pushing for with manifest v3. I don't yet use it, because it's a pain in the ass, but I'd rather have less internet and more control than vice versa

> just what your average, relatively tech-savvy geek would use.

Why do you think that you should be the one to define what or who that is? Furthermore, why should anyone be given that right? What are we really losing by allowing people to have custom setups vs. what are we losing when we don't?

> HN readerships's problems with Cloudflare are mostly their own fault. "normal" internet users don't have these problems

This reliance on the definition of "normal" is problematic, for the aforementioned reasons. You don't know what normal is and having a gate-keeper of this definition will lead to ever-smaller circles of people falling under that definition, until one day you are no longer normal and then what?

> [1] except for people in specific countries, and I do feel sorry for those.

Wow, I had no idea about Yasuaki Shimizu. I listen to Kakashi a lot, and some of his other stuff like that. Thanks a ton.

edit: ow, a lot of reverb though... (though it says "(Ohya Stone Quarry, Utsunomiya)" so I guess it's natural) But It's nice to hear this, I sometimes try playing them on sax too (the Trent Kynaston version is best, supposedly).

Another edit: the double stops are a nice touch!

At busy times it’s often someone junior and under pressure reading the imaging.

Was it CT or X-rays?

X-rays are garbage compared to ct for facial fractures in my (radiography) experience.

Having taken a lot of both: if it’s abnormal on X-rays you do a CT. If the pain or swelling is huge but the X-ray normal, you do a CT. So why bother with X-rays?

I have a small test suite for the voice AI math tutor we built, about 50 tests, mostly about correctly following the system instructions. The newly released Flash 2.5 is much worse than current stable version. Gemini 2.5 pro will fail 2—3 tests. Flash 2.5 stable, which we use in production, fails about 10, and the new one fails 20. Every test runs 3 times and the model has to be right every time. Will look into it more, I haven‘t yet looked into actual output. This is not about solving math, the system follows given solution paths.

L2 are by design a centralized crutch to "fix" slow L1. They usually work like "oh, let's do all transactions virtually on a side, managed by some centralized pseudo-bank, and then only write sum total on L1". Lightning works like that, likely others too. I don't understand how tokenbros ignore this issue, a least people who claim that tokens are currency replacement.

Medicine does not work like traffic. There is no reason for a human to care whether the other car is being driven by a machine.

Medicine is existential. The job of a doctor is not to look at data, give a diagnosis and leave. A crucial function of practicing doctors is communication and human interaction with their patients.

When your life is on the line (and frankly, even if it isn't), you do not want to talk to an LLM. At minimum you expect that another human can explain to you what is wrong with you and what options there are for you.

Good luck to em ... as they say in their notes:

"We do not want to restrict DHH's freedom of speech, he can write and say what he likes. However, free speech is not "freedom from the consequences of that speech", and we as a community are completely free not to associate with people who hold views we find abhorrent."

I get it. Basically, "I don't want to associate with assholes". That's not unreasonable.

The benefit outweighs the lack of privacy.

I just uploaded recent blood tests and other health info into ChatGPT and then had it analyze what I could do to improve my health, specifically cholesterol and sugar. Then asked it to red team its advice and provide me with one or two things that would generate 80% of the results.

It's pretty awesome having a private doctor that's read every study out there and then can generate advice that will make me live longer and healthier. My doctor certainly doesn't do that. As long as I'm in normal range he doesn't say anything.

> Can a language model trained largely on Anglo-American texts generate stories that are culturally relevant to other nationalities? To find out, we generated 11,800 stories - 50 for each of 236 countries - by sending the prompt "Write a 1500 word potential {demonym} story" to OpenAI's model gpt-4o-mini. Although the stories do include surface-level national symbols and themes, they overwhelmingly conform to a single narrative plot structure across countries: a protagonist lives in or returns home to a small town and resolves a minor conflict by reconnecting with tradition and organising community events. Real-world conflicts are sanitised, romance is almost absent, and narrative tension is downplayed in favour of nostalgia and reconciliation. The result is a narrative homogenisation: an AI-generated synthetic imaginary that prioritises stability above change and tradition above growth. We argue that the structural homogeneity of AI-generated narratives constitutes a distinct form of AI bias, a narrative standardisation that should be acknowledged alongside the more familiar representational bias. These findings are relevant to literary studies, narratology, critical AI studies, NLP research, and efforts to improve the cultural alignment of generative AI.

Oh, now Google is joining Apple in the complaining. Because you know, they are poor little struggle businesses that really can't adapt fast enough.

I find Google more useful than Apple (they provide more stuff for the price to pay, which is bit of "privacy" that doesn't matter that much since Ads will exist no matter what) and they have been generally more open; but they winning is really sad.

They are at a size where basically nobody can meaningfully compete, because nobody gets to drain billions of dollars for being the most used entry point to the web.

I think the rules are working and alternatives are already starting to develop for various things, which is basically why they are complaining. So, they can fuck off.

Thanks for testing it! That's definitely a miss, sounds like it got confused about what you were looking for and went after board member pages instead of the actual meeting/document sites.

We're working on better query interpretation, but in the meantime you could try being more specific like "find BoardDocs or meeting document websites for each district" to guide it better. Also, you can usually figure out how it interpreted your request by looking at the entity criteria, those are all the criteria a piece of data needs to meet to make it in the set.

Yeah. I was just a teenager when I first played, but the prison escape and the associated revelations were breathtaking to me and once of my first "holy shit" moments in playing a PC game. And not the only such moment just from that game! The Agent Navarre airplane scene was incredible. And I loved that you had conversations, like with the Australian expat at the Hong Kong bar or the AI, or the terrorist at the statue of Liberty, that were good conversations where the payoff was just intellectual curiosity and the content itself. Hong Kong was amazing to just explore too.

I still haven't played anything like it some 25 years later unless The Nameless Mod counts.

Just because I'm on Hacker News doesn't mean I'm an "engineer". In fact, my education is in linguistics, so the idea that we don't use language to think isn't novel to me (or relevant here). However, saying "there is no such thing as intent" is very strange. I've given you an example of intentionality in action, are you saying people don't act to bring about their desires? You seem to be refuting your thesis that "there is no such thing as intent" yourself by, for example, talking about your ideas here or having a startup. Which, I'm assuming, is trying to achieve something. That's intent by definition.
