This is significant, and I think ironic. I cringed when I read this as the conclusion to that massive military study.

This platform appeals to those who would have it the other way. Those who break the cognitive lazy barrier (like those who break the brute labor inhibitors) are empowered beyond the expectation and conclusions of all others. Those who would be dependent as opposed to those who would own their knowledge and experience internally.

Cognitive effort experienced as unpleasant?

For some I can only imagine sex is unpleasant.

News for you others, or maybe you all for it is not always true that we recognize in ourselves our most prominent qualities.

Without cognition of a thing, the nature or understanding of that thing cannot be one’s own. This applies to everything from your tools through society and civilization itself.

One can only be said to “have” knowledge and experience that one has put one’s self through. One can only be said to “own” that knowledge when one could convincingly recreate those product outcomes from basic essential forms.

Having our challenges accomplished for us is “pleasant” and arguably more “energy efficient”, yet diminish our capacity as competent actors on our own behalf.

I think everyone has experienced those moments when we realize others, fully formed self responsible adults, are by virtue of their technological crutch not fully formed or self responsible.

This cognitive inhibition is the root cause.

Also, didn't early Arduino heavily borrow from another open-source project, "Processing"?

Processing was/is graphics-centered, so that's where Arduino's term "sketch" come from, if you ever wondered.

I read this comment and it matched my experience so closely I had to double check it wasn't a copy of one of my own posts.

We really do need an update to the diagnostic criteria and descriptions for ADHD, Autism and their combinations (DSM6?). I think monotropism is a good overarching description that aligns better with what we with these diagnosis experience.

> The market decided a long time ago that movies, songs, books, photographs etc were, in fact, worth nothing. That's the effect of digital media. It's completely incompatible with the free market.

This is such a willfully ignorant take, it’s wild. Anyone who has a cursory understanding of game theory can see that if this were true a simple recursion would occur:

1. Everyone would pirate movies/tv/books. 2. There would be $0 in producing media. 3. Significantly less media would be produced. Anything capital intensive would be gone. 4. Demand for anything that could be produced would skyrocket. Imagine putting together a blockbuster film when the world hasn’t seen one in a century. 5. People would pay money for the product of 4.

Just because we can get something for $0 doesn’t make it worth $0. I could enslave my neighbors and make them work for me, that doesn’t make human labor worth $0.

When I studied chemistry at university, only a handful of select students were introduced to the nuclear science lab in the basement. It had a lot of spicy isotopes, neutron sources, etc. Even as a chemistry student with free run of the place for years I had no idea it was in the building until the department head pulled a few of us aside.

The reason for the informal secrecy, as it was explained to me, is that every so often someone would find out there was plutonium etc in the basement and have a public freak out, including on occasion other (non-STEM) professors at the same university. These people would try to organize crusades to get it shut down because evil. Intentionally obscuring its existence greatly mitigated this drama. They appreciated us continuing the tradition of keeping it out of sight and out of mind from the general public.

The publicity around this Kodak case was an example of why no one talks about nuclear labs. The public cannot be trusted to engage in a discussion about anything “nuclear” in good faith. There are quite a few areas of science like this.

Just open-sourced a ~320-line Numba heuristic that consistently hits 0.3674–0.3677 on the standard G81 benchmark (20 000 nodes, 40 000 edges).

Key points: - 99 % of the final cut is reached by iteration ~1200 - Built-in early stopping turns the remaining hours into minutes - <80 MB RAM, no external solvers, no GPU

Quick comparison on the exact same graph (my runs, nothing fancy): • Random 0.258 • Greedy (10 restarts) 0.324 • Simulated Annealing 0.349–0.356 • Basic Tabu Search 0.362–0.365 • Goemans-Williamson theoretical 0.878 → completely unusable at this scale

GravOpt at 1200 steps already beats almost every classical heuristic and is 50–200× faster.

Code + the official G81 file (auto-downloaded if missing): https://github.com/Kretski/GravOpt-MAXCUT

Just run python gravopt.py and watch it go (downloads G81 automatically).

Did I just rediscover a 90s metaheuristic with better convergence + early stopping, or is this actually useful for 20k–200k QUBO instances in 2025?

Flame away, I can take it :)

It's a bit of a weird edge-case, but the very popular Battlefield 6 is partially a Godot game. It's an odd hybrid of a proprietary in-house engine with Godot grafted onto it, which serves as a public-facing SDK for players to build their own content. I know that's not exactly what you meant but it is an interesting application in a major AAA title.

In what qualities was Mussolini a socialist? Anti-capitalism never passionated him much. Indeed, he had a lot of support from the capitalist class, which he gladly took. Similarly, one of the first things the nazis did upon gaining power, was to arrest all communist and socialists, and make unions illegal within Germany.

Your mixing up of the two concepts is wrong and unhelpful. Certainly, the Soviet State was fascist in many aspects. But many fascist states emerge from capitalist economies, with help from the capitalist class.

To those not familiar with LA or the USA, here’s a cultural time capsule from 2Pac circa 1996:

“ It's the, City of Angels and constant danger South Central L.A., can't get no stranger Full of drama like a soap opera, on the curb Watchin' the ghetto bird helicopters, I observe”

Pretty much still sums it up.
Building an AI generated animated kids yoga video for $5 in 48 hours
by lucassmedley | 2025-11-22 13:30:05+00:00
I'm in the middle of switching jobs and have found myself with 2 months of gardening leave. After working with LLM applied AI the last 2 years, I wanted to try more applied work with video, image and audio models.

Meanwhile, my brother was showing me his son loves these kids yoga videos on Youtube. On inspection, the videos tend to be of quite low production value and quality and still consistently rack up millions of views.

So, I decided to use my time and see if I could fully AI generate a Pixar style animated yoga session for kids. The final result is a c. 8min video, generated for around $5 total (amortising subscription costs). I'm the first to admit its not that professional and quite janky, but I'm quite impressed with the results (I also have no prior video creation or editing experience). Generally the hardest thing was trying to avoid the whole thing just feeling like slop.

My stack was using Google image and video models, Eleven Labs for audio and Capcut for editing. And that's it! Happy to a full write on on how I spent the 48 hours if people would find it helpful.

Video here: https://youtu.be/GPyTLsI0CYU?si=kaLLjN0j3g12U75M

Would love any feedback and hope it can be nice for those of you with kids!

Advanced diffusion certainly benefited from the acquisition speed ups. That is its biggest challenge in my opinion preventing it from wider clinical adoption. It takes too long to get enough images for the models. Hyperpolarized MR will run into issue of lack of expertise in clinical imaging centers. There is already a shortage of good techs and MR companies are working to further automate the workflows. Unless there is a major benefit of the advanced techniques, people will stick to the bread and butter FSE and DWI.

Beyond obvious tumors/lesions/clots/abnormalities, we are not even close to being able to identify the cause of organic anxiety or mood disorders even if we wanted to.

We can say certain behaviors, experiences, illnesses and some genetic identifiers can trigger the conditions, but not the underlying cause. We can say things like some therapy and medication can help with the illness, but not the cause.

Not to trivialize therapy, but for many illnesses, not just mental, a portion of it can be described as ways of learning to live with the illness, not necessarily treating the underlying cause.

> Obesity has skyrocketed across the whole world. People already eat too much, too much hyper transformed, too much sugar, too many calories.

Carbohydrates are way cheaper, but the distribution of nutrients you can get for any price has not gotten cheaper proportionally. Then you factor in choices, like paying rent vs eating healthier, etc etc.

It's also worth noting that the xz exploit didn't even live in the xz source, it was added to the source by the attacker before uploading it to the package build farms. With most of the current package repositories, there's not even an expectation that the bundles you get are derived from a particular tag or commit hash, let alone a detailed chain of custody. I remember RPM in the old days made a big deal out of "pristine sources" to which patches would be applied, but it still has no way to prove or enforce that claim.

> But I do think its possible to get good socialization exposure while homeschooling.

Absolutely. I was homeschooled and in my state (Illinois) the laws work out such that homeschool students can enroll in public school classes if the school has space for them. That's how I socialized. So I got at least a modicrum of socialization (especially once I started band) but wasn't dragged down by the mediocre education at our local public schools.

From the comments:

> This story is really old news. The Atlantic profiled this guy and his “research” last January and then MIT basically disavowed him in May. Multiple journalists on Substack covered this months ago, too…. As I read this story I thought I was having major deja-vu … even the photo is reused. Why is it being rerun now? Did something change?
Show HN: Mamba2-Jax; Mamba2 implemented in pure Jax/Flax
by cosmonaught1337 | 2025-11-22 13:34:03+00:00
I ported the Mamba2 state-space model (“Transformers are SSMs”) to pure JAX/Flax as mamba2-jax.

– Core Mamba2 block with LM (Mamba2ForCausalLM) and time-series (Mamba2Forecaster) heads – Pure JAX/Flax (no Triton/custom CUDA), runs on CPU / CUDA / TPU via standard JAX backends – Small CPU-only parity test vs mamba2-torch: similar loss curves, final MSE diff ≈ 0.012, prediction correlation ≈ 0.99; after JIT warmup JAX was ≈ 2× faster per step

I’d really appreciate feedback on: – API design, especially for streaming/stateful inference – Performance gotchas you hit if you try it – Any hooks you’d want exposed for research use

PyPI: https://pypi.org/project/mamba2-jax/

Thanks, Cosmo

Back in 2015 when the Rust project first had to disable use of LLVM's `noalias` they found that performance dropped by up to 5% (depending on the program). The big caveat here is that it was miscompiling, so some of that apparent performance could have been incorrect.

Of course, that was also 10 years ago, so things may be different now. There'll have been interest from the Rust project for improving the optimisations `noalias` performs, as well as improvements from Clang to improve optimisations under C and C++'s aliasing model.

Agree with each of your points, but must add some counterpoints as illustration:

Land of the free, home of the brave, there are some Americans who will rebel against the requirements and constraints of their lifelong socialization. I think this is an underappreciated factor in the study of homelessness-- people fight to be free, and as the song goes, Freedom is just another word for "nothing left to lose". There is some serious freedom that does along with having only the clothes on your back and whatever is in your pockets...

Where were you and others encountering these homeschooled kids if they were locked up in their cosseted homes in which they were apparently never socialized?

As another reply pointed out, maybe these kids are “weird” in some way, maybe they are not. We don’t have more than anecdotes here. More importantly, and to the point of my first reply, we don’t know the motives of their parents. The GP was engaged in mind reading. Certainly, the motives are manifold. One motive may be, “I’m going to home school my kid because he’s weird and won’t do well in a public school.” We don’t know which way the causal arrow points.

No you can't.

You can blame the endless amount of people that jump in these threads with hot takes about technologies they neither understand or have experience with.

How many event sourced systems have you built? If the answer is 0, I'd have a real hard time understanding how you can even make that judgement.

In fact, half of this thread can't even be bothered to look up the definition of CQRS, so the idea that "Storing facts" is to blame for people abusing it is a bit of a stretch, no?

I am always delighted when I come across a good one, but finding good ones is the problem. Ross Wilkinson (CSIRO) many years ago said there were 3 ways to find things: browsing - from were you are, look about. If you're in the high street and hungry, walk and look. It is no use knowing what is 5km away or what was available there 6 months ago. Categories are another - think Dewey Decimal system. These are expensive to produce and get out dated, but you know when something is _not_ available. Third is tags attached to items and a search engine. Content words at good tags but the challenge is to stop vested interests gaming the system - telling you you can get it through Amazon tomorrow when you could get it from across the road today, or when The State doesn't want you to know what "the Russian Narrative" is (other than "it's bad"). A search engine specifically for blogs would be great if we knew how to make it work in the long term.

> It goes the other way as well. It is dumb to run away from police when they stop you for minor infraction and face a very high chance of getting caught and getting into a major problem

Right, people are dumb. You can't just throw your hands in the air and declare a problem unsolvable because people are dumb and keep acting against their best interest; you acknowledge that fact and change tact accordingly. If it turns out that trying to pull people over for minor infractions causes 1% of those incidents to turn into violent chases then you should stop pulling people over for minor infractions and figure out a safer way to ticket them. At the very least you shouldn't chase after them in your car and add another dangerous vehicle to the road. It reflects a mindset of "get and punish the bad guys" being prioritized over "improve safety of your community," which pretty much sums up the culture problem with American police and criminal justice in general.

Because Nano Banana is better than wasting time for someone who isn't a 10 year veteran of MS Paint arts.

I'm tired of this kind of argument from anti-AI folks.

"Why not pick up a pencil instead?"

What if illustration was never "art"? What if it was always just a rote mechanical skill and the art itself was what the person was trying to communicate?

Maybe the technical aspects don't matter. Maybe it's the message we're conveying, our taste, our curation, our unique lens?
by b112 | 2025-11-22 13:38:13+00:00
I recall when I entered college. The first thing was mandatory, required, english classes.

The logic was, if you cannot communicate, you cannot explain why your job, or what you're doing is important. If it has value. If you have value. You cannot hope to explain requirements to others. Or explain the logic or reasons, the "why" of a technical path.

You're likely correct that a lot of people think this unimportant. To them I'd say, they're severely limiting their career, if they don't think communicating is important.

Well, it's well known that ADD/ADHD aren't about lack of focus, but about an inability to direct one's focus to where it's needed.

Normal people can think "I need X, let's work on X" but ADHD people are at the mercy of what's "chosen for them" by their brain.

This was probably fine 4000 years ago, when the world was looser, and people could find their place in life regardless of their particular quirks, but not so much nowadays.

This difficulty or inability to direct focus can be "trained away" with enough effort, but it isn't easy at all.

I've been building agent type stuff for a couple years now and the best thing I did was build my own framework and abstractions that I know like the back of my hand.

I'd stay clear of any llm abstraction. There are so many companies with open source abstractions offering the panacea of a single interface that are crumbling under their own weight due to the sheer futility of supporting every permutation of every SDK evolution, all while the same companies try to build revenue generating businesses on top of them.

If you are considering event sourcing, run an event/audit log for a while and see if that does not get you most of the way there.

You get similar levels of historical insight, with the disadvantage that to replay things you might need to put a little CLI or script together to infer commands out of the audit log (which if you do a lot, you can make a little library to make building those one off tools quite simple - I've done that). But you avoid all the many well documented footguns that come from trying to run an event sourced system in a typical evolving business.

To be fair to the parent, despite what they think about the lockdown decision now, it says nothing about whether or not they thought it made any sense then.

It's perferctly possible to believe that the lockdown was a reasonable decision with what was known then, and still believe that the lockdown is to blame for certain unavoidable consequences down the line. Again, the parent might not believe this as well but their point can be taken separately fron your complaint.

Since several generations of Americans are not familiar with a drawn out sustained attack on acceptable cost-of-living parameters, the observation that "people are more awful" should be familiar to many people who lived and endured in places that have had decades-long deteriorating econonmies. If the economy or subjective economic perception had not tanked post-lockdown, the awfulness of people would be much less pronounced I believe.

"Wiring", which constitutes Arduino's primary API surface, was taken wholesale from Hernando Barragán's 2003 master's thesis project. It was a fork of processing for microcontrollers and was not written by the Arduino team: Massimo Banzi, David Cuartielles, David Mellis, Gianluca Martino, and Tom Igo.

This is just like how universities hide their animal research facilities. It wasn't until the final year of my biology degree that I found out we had a basement floor under our life sciences building where this research is carried out.

I visited a few times as part of a research project I was involved in, and that experience was one of the factors that put me off pursuing a career in biomedical research.

Well, plants famously don't eat much more than sun light, water and carbon dioxide. Otherwise they just need phosphorus, nitrogen and some trace elements.

Moss has already adapted to barren environments. Its niche is growing where nothing else grows. Like, on top of rock. It's not having roots, not mingling with modern temptations in the soil. Most mosses actually aren't doing well in competitive, complex ecosystems full of nutrients and such.

It's not an ignorant take, it's reality. If you don't want that outcome, stop supporting outdated economic theories. I didn't say I wanted this to be the case, I said it is the case. The only reason digital media is sellable at all is due to laws and regulations. Not only are these laws and regualtions historically anathematic to those who defend the outdated economic theories, they're also protecting the wrong people. The distribution networks get a much larger share of profit than the actual creators.

People should exchange money for digital goods. That money should go primarily to the creators of those goods. None of this is happening very much, and it's actually moving in the wrong direction.
