Well the truth has finally been openly accepted by the universities themselves. They sell fancy pieces of paper with your name on them in nice calligraphy, not knowledge.

I can't imagine having so little respect for my own reputation that as a professor I'd throw out unreviewed AI slop as my own intellectual work, but I bet nobody is getting fired for it so that's just a sign of my own stupidity. A professor with no pride, working for a university with no pride, giving students with no pride certifications that they can use to get ahead in an economy with no pride.

I'm bullish on AI in education, because of the possibility of creating an individual student model that the machine can use to constantly target weaknesses in understanding. But that hasn't been invented yet. What you would get now is a teacher that hallucinates, simply lies to bridge gaps, forgets what it was supposed to be talking about, and constantly fabricates references.

> I picked up an Xperia

I had an Xperia for awhile. I liked it while it was new, but after a year the back started peeling off.

Pretty lousy for a phone that was supposed to be waterproof. At that point I realized that the Japanese change out their phones every 6-12 months, thus Sony didn't realize that the market demands much longer reliability in a smartphone.

U-net is a brilliant architecture, and it still seems to beat this model in scaling up the segmentation mask from 256x256 back to the real image. I also don't think unet really benefits from the massive internal feature size given by a the visual transformer used for image encoding.

But I'm impressed by the ability of this model to create a image encoding that is independent of the prompt. I feel like there may be lessons in training approach that can be carried over to unet for a more valuable encoding.

If anyone wants an example of actual jailbreak in the wild that uses this technique (NSFW):

https://www.reddit.com/r/persona_AI/comments/1nu3ej7/the_spi...

This doesn't work with gpt5 or 4o or really any of the models that do preclassification and routing, because they filter both the input and the output, but it does work with the 4.1 model that doesn't seem to do any post-generation filtering or any reasoning.

> I think it's because people love the idea of what they think GDPR actually represents (the fuzzy abstract idea of "privacy"), without ever diving into any of the implementation details.

I've implemented it like a half-dozen times. Why do you think I'm so confident? It's truly not very difficult, particularly if you don't have to retrofit some hell-app that uses a billion cookies. For the most part, collecting PII is already a liability and you don't want to do this anyway outside of critical information (e.g., email).

> I honestly think these small inconsistencies are irrelevant in the big picture of building something complex.

Big picture is PHP is a poor tool. I enumerated only one annoyance about writing software on PHP, 80% of all websites on the web being built on it doesn't make it any better. Some companies keep building on it, because:

1. They started writing the codebase in PHP, now they are "locked" (cost of switching to another language is extremely high)

2. Hiring PHP developers usually costs a lot less (at least 20%) than say Java/Python developers

People keep arguing that, for seasoned developers it doesn't matter what tool one chooses. Then what is the point of choosing a tool over another, if you gotta check the docs constantly for inconsistencies? (I'm sorry, you gotta use IDE anyways)

With that said, there is no ideal language, however PHP is single most annoying language after JavaScript.

Currently working on a SaaS app that could be called an "AI Wrapper". One thing I picked up on is once you start using AI tools programmatically, you can start doing far more complex things than what you can with ChatGPT or Claude.

One thing we've leaned heavily into was using Langgraph for agentic workflows and it's really opened the door to cool ways you can use AI. These days the way I tell apart an AI "Wrappers" vs "Tools" is what is the underlying paradigm. Most "wrappers" just copy the paradigm of ChatGPT/Claude where you have a conversation with an agent, the "tools" are where you take the ability to generate content and then plug that into a broader workflow.

Python managed to do this by not actually checking the types at runtime. If you declare a list[int] return type but you return a list[string] then nothing happens, you're expected to prevent that by running an offline typechecker.

PHP chose to check types at runtime. To check that a value is really an array<int> the runtime could have to loop through the entire array. All the types PHP currently implements are simple and cheap to check. For more elaborate cases you need an offline checker like PHPstan and comment-based type annotations. (PHPstan catches 99% of issues before the runtime gets to it so for my own code I'd prefer the Python approach with its cleaner syntax.)

The runtime checking seems the key difference, not so much the historical strength of the type system. Python's language implementation does very little typechecking itself and PHP's third-party offline typecheckers are respectably advanced.

Have very fond memories of playing J2ME games. Here's some off the top of my head: Zombie Infection (what a great game!), Galaxy on Fire, Sims, Age of Empires, Real Football, Orcs&Elves, Pokémon Crystal on an emulator...

And of course a limited port of Worms Armageddon that has to be one of the games I sunk the most time on, seeing as I played several matches a day with my friends for an entire school year! Ahh I even scribbled a "campaign mode" on my math notebook during class instead of paying attention!

My wife and I will actually be going to an exhibition of Watterson's work this weekend—we're lucky enough to live not too far from Cooperstown, NY, where the Fenimore House Art Museum has the exhibition running all this fall.

As an '80s kid, Calvin and Hobbes ran for almost my entire childhood, and we have a number of the collections. I never fail to be impressed either by Watterson's talent, both in the art and in choosing the right words to say, nor by his integrity and restraint, both in refusing to allow his work to be merchandised and in choosing to stop when he did—when he felt he had said all he came to say.

Many more artists of all types could take so many lessons from him. Even some that are already great. He is a very humble man, but he stands among the legends of our time.

Edit: realized it would be good to add a link to the exhibition: https://fenimoreartmuseum.org/future-exhibitions/calvin-and-...

> I've been saying we need a separate Internet for kids.

That is moronic. And destructive.

Children are human beings, and are supposed to get a chance to grow naturally into being community members. That is an incremental process. Not everybody does all the parts in the same order, nor at the same rate. And you don't suddenly snap from being a "child" into being an "adult", and reboot all your human connections in that moment.

You don't mature at all without interacting with some adult role models (not just seeing them from afar, and not just seeing the parts people want to show you). No, your parents are not enough. You also need to interact with slightly older, and substantially older, non-adults. The tight age cohort isolation produced by schools is already destructive enough to social development.

Children are also entitled to have access to information and activities, just like everybody else. And, no, not all of that would somehow get duplicated into your child ghetto.

And it means absolutely nothing that people "used to do that just fine without the Internet". That was before everything was done via the Internet.

> Not just because of pedos, but because young adults don't have the same level of respect and filters that one should have when dealing with kids and it's exposing them to behavior they shouldn't.

Get a fucking grip. Kids can handle knowing about behavior you don't like. They can handle knowing about really bad behavior. They can handle seeing what older people do,and what the consequences are. In fact, that is essential to the development of their own values and capacity for self-governance.

If you raise somebody in a box until the age of 18, don't be surprised if they can't deal with the outside world when you force them out of it.

>you will get pulled over just speed anyway

If this is in Texas, absolutely. Doing 75 in an 80 is suspicious AF.

A few decades ago I did contracting work on Texas military bases; I would always smoke a pre-rolled blunt between the border bases and inland-checkpoints. To the chagrin of drug dogs just looking for people to harass (surprisingly: rarely me).

>don’t ride dirty

We were always taught to only break one law at a time.

The model is massive and heavy. I have a hard time seeing this used in real-time. But it's so flexible and accurate it's an amazing teacher for lean CNNs; that's where the real value lies.

I don't even care about the numbers; a visual transformer encoder with output that is too heavy for many edge compute CNNs to use as input isn't gonna cut it.

As a counterpoint to the selectorate theory, see Thorsen's PhD dissertation, "Only In It for Power and Wealth?", https://politica.dk/fileadmin/politica/Dokumenter/Afhandling...

The thesis argues that dictators regularly both harm groups clearly inside the winning coalition, and please groups clearly outside of it. A common, but not the only reason, is ideology.

One has to be careful when using game-theory models on messy human entities. Sometimes it works, sometimes it doesn't, and it's hard to determine just at what point the model breaks down. At least without empirical research.

(Another example is that actual negotiation outcomes rarely end up at the minimax or Nash product equilibria that game theory sequential negotiation concepts would suggest.)

You took a very specific argument, abstracted it, then posited your worldview.

What do you have to say about the circular trillions of dollars going around 7 companies and building huge data centers and expecting all smaller players to just subsidize them?

Sure, you can elide the argument by saying, "actually that doesn't matter because I am really smart and understood what the author really was talking about, let me reframe it properly".

I don't really have a response to that. You're free to do what you please. To me, something feels very wrong with that and this behavior in general plagues the modern Internet.

Sorry I mis-worded that. It was my BRAIN being in plan mode (I know CC has a plan mode).

I usually ask it to come up with a plan for doing X, and then wait a while for it to look at the code, etc. But in some odd way, GPT-5.1-Codex-Max came up with a plan within 5 seconds. I just found that surprising.

If we dismiss the possibility that the post itself is a part of Russian propaganda to whitewash the soviet legacy (which they are engaging now at scale), then the next best explanation is that the author lacks the context of living in the USSR to correctly interpret the recordings.

In USSR everyone lied. Telling anything against the party will put you and your family in grave danger - it is basically a suicide. There were no free press, no activism, and all information was filtered by the party with complicated process of deciding what should be published and when and who gets punished for what.

People in the west have no understanding what it means to live all your life in such conditions so they try to interpret people as if it happened in their country.

It can be that the person was trying to make amends with the party to ease the social ostracization for his family, friends or colleagues. It doesn't mean the person is telling the truth at all, it means that he show loyalty to the party line by telling that the system was efficient and all his higher-ups were doing the best job.

Yes, and we are screwed either way if we use Windows with Recall, or even in general.

I would not consider Windows secure at all, and it seems futile to use a privacy-oriented IM on Windows, it really defeats the purpose.

Imagine using Windows with Recall enabled that takes screenshots of your conversations all the time. You can be using the most effective IM for privacy but it would not help.

So what is the moral of the story? We have shitty laws, and you should not use Windows. :P

This implies that the anti-prompt-injection training is basically just recognizing that something looks like prompt injection, in terms of surface features like text formatting?

It seems to be acting more as a stylistic classifier rather than a semantic one?

Does this imply that there is a fuzzy line between those two, where if something looks like something, then semantically it must be/mean something else too?

Of course the meaning is actually conveyed, and responded to at a deeper level (i.e. the semantic payload of the prompt injection reaches and hits its target), which has even stranger implications.

Disapointing lack of technological specs. Basically a long form ad or customer landing page. Also whoa, that's about 5x as much thermal paste as you need.

1. The paste shouldn't touch the perimeter conductors at all and

2. Ideally should be less than 1mm, manufacturing specs put this at less than 50um!

As for noise I feel like you should at least mention the "Shroud" and baffle have nothing to do with the noise reduction - the fans are 50% larger, require 1/3 the rotational speed(I did no calculation beyond personal experience math nazis) and have no baffle at all.

I worked in the tech side of education until 15 years ago or so, and it was already clear how problematic it was getting.

Distance learning was basically a dimly-lit grainy video, recorded 5 years prior, all acquired from the same provider and being shown to hundreds of classes all over the country. Instead of teachers, "tutors" (we couldn't call them teachers for legal reasons) making barely above minimum wage answering questions of dozens of classes and grading things on Moodle/Blackboard. A real teacher would be responsible for a class but they would barely see anything happening online, as they were just figureheads already busy with real classes.

I also remember some courses having almost half of the courses being long distance, so even people choosing traditional education were pushed into doing cost-saving computer shit.

The computers in the campus were obviously miserable to use, so I did everything in my power to at least make the software light enough so that people wouldn't suffer much, but in the end I hated myself for being in that industry.

You know, your comment reminds me of something my wife and I were talking about. We have been starting to let our child have a little more screen time and choose what he wants to watch (within the parameters we set).

Some shows and movies seem harmless, initially, but then we noticed in so many kids movies (e.g., Zootopia, Sing), they're always yelling at each other, expressing anger, frustration, and hostility towards one another.

Then we wonder why kids adopt those attitudes. It's simply because mimic what they see. And worse yet, when they see it in movie/show form, they think those attitudes are cool and relatable.

I replied to a comment posted 9 hours before my comment, don't come chastise me, thank you very much.

I replied to what I read: you defending that communications between the government and businesses don't need as much transparency as possible.

The rest of the comment is just trying to support this absurdity in too many words.

Seems like every mask is one pass. So even multiple penguins are multiple inferences. But if it continues from SAM 2, the heavy compute is the original image encoding which is reused and cashed for every inference.

No idea what they will do for their API, but from a compute perspective the prompt is free once the image is processed.

Well, it's not intractable if it's pushed to the underlying hardware and signed drivers.

Valve could build something into their chipset and start signing the Steam Deck drivers, create secure boot etc and essentially create an Apple SIP equivalent. Wouldn't work for the rest of the Linux ecosystem or other devices, and people would absolutely howl about it, but they could do it.

In a case of the worst person you know makes a great point, Jordan Peterson was remarking a few years back about how Youtube and MOOC's were really the new universities of the modern age. If you want knowledge it's there for the taking.

The legacy institutions really are just a stamp / sorting hat for young people these days.

For the money people spend these days on education, you'd think there'd be grounds for refunds based on false advertising of the product.

I’ve been working on a small tool called ShowcaseHQ that solves a problem I kept seeing when talking to indie fashion brands: creating line sheets is surprisingly painful.

Most small brands either: • hack something together in Canva/Figma, • export messy PDFs, • or skip line sheets entirely because it takes too long.

I built a lightweight generator that lets you import products (or pull them directly from Shopify), choose a layout, and instantly generate a clean line sheet you can send to buyers. No design work needed.

I rebuilt the UI this week after user feedback - simpler navigation, less clutter, and a much faster flow.

What I’d really love from HN: • feedback on whether the problem is actually meaningful, • whether the onboarding feels smooth, • and anything that seems confusing or poorly executed.

Happy to answer any questions about the stack, decisions, mistakes, etc.

Well, isn't the idea that you use apps compiled from source by distro maintainers, which are separate from the upstream maintainers ?

Frankly, I still trust this model much more than black box Android apps automatically updating in the background, sending tons of telemetry and demanding random permissions so they can spy on you.

Not to mention the security model preventing many useful things from working properly (try to get a SFTP working on an Android system so that you can copy out photos taken by the phones camera.

I think this stuff is super important, simply because there is a ton of stuff we can't do using our phones today.

Think mesh networking, resilient ad-hoc application clustering, non-Internet P2P, like Freifunk but everywhere. We shouldn't have to depend on Google or any of the big tech companies for anything except the hardware.

That would offer much more freedom. There are also contexts where this kind of thing could also enable life-saving applications. And unlike todays Internet where a database query in Cloudflare or a DNS bug in es-east-1 can disrupt half the services we use, this kind of technology really could withstand major attacks on infrastructure hubs, like the Internet was originally designed to do.

This is the culmination of decades of cuts to education. I mean, what else was going to be the end point of having teachers buy supplies for their own kids, demonizing professors, demonizing higher education and the idea of education generally, not training enough teachers, and underpaying the teachers you already have.

In America we have to deal with school shootings, the latest religious group mandating the 10 commandments be put up or rainbows be taken down, irate parents mad that you failed their kid who didn't do work all semester and has severe behavioral problems no one is allowed to discipline. And now of course with AI, the students aren't doing their work, and if you call them out on it they call their parents, they sue, you get deposed and have to admit you can't 100% prove it's AI... so why bother? Who would ever want to grow up to be a teacher anymore?

So yeah, cut education, end up with AI students submitting AI papers to AI teachers. We have arrived.

The only question now is... what are we going to do about it?

My problem with 2) is: it works. If you look at most movies; both the way they are made and the stories they tell is really subpar these days and this has grown worse in the last decade or so. It's not the fact that CGI is used, it's the really lazy and sloppy way that it's used. Same goes for the stories: there are so few films that have a real story to tell that I have mostly stopped watching movies at all.

There's this YT channel - Like Stories of Old - I love who made an episode precisely on that topic: https://youtu.be/tvwPKBXEOKE?si=180Wkylrx-L5zOsI He calls it the haptic of a movie.

I'm totally convinced the industry can sell AI generated media just fine, even with the attitude you described.

EDIT: in similar vein the settings of movies/series are equally minimised, particularly in fantasy. Take for example Game of Thrones, Winterfell. This setting could never have worked in reality and yet people loved it. Brett Deveraux pointed out how silly it was and still.https://acoup.blog/2019/07/12/collections-the-lonely-city-pa...

What a profound and beautiful comic. The art. The storytelling. The expanse of Calvin's vivid imagination.

Every day, I have a reminder to think of three things for which I'm grateful. I was just trying to find the third for today when I saw this headline.

I am grateful that I love my tattoos (and have no regret, which is the risk of tattoos), one of which is Stupendous Man. He was the first and it's because CnH holds such a special place in my heart. The comic largely shaped my childhood.

Bill Waterson had the integrity not to license his work, preferring that the reader not have the characters spoiled. He opted not to make boatloads of money in making this decision (cough, garfield, snoopy). He also declared that Sunday papers could print his comic unbroken or they could drop him and this allowed for truly magnificent art pieces where stories could be told in new ways. His integrity is legendary in the field.

Check out his recent work, The Mysteries.
