dTal··on WPD won't replace stolen Flock cameras, citing public trust
It's not "neutral machine-based enforcement", it's a general purpose panopticon that tracks and logs everything, ready to be queried later by arbitrary people for arbitrary reasons.

useful heuristic: every comment I've seen with excessive 9s was nonsense

You really think if I asked 200,000 people in my city, only one would have heard of Meta RayBans? when there are billboards, magazine ads, and window stickers in every glasses store? Couldn't tell you the real number but it's probably closer to 1 in 5.

Not uncommon, in comments like these, for there to be so many 9s that the population of Earth is exceeded.

dTal··on Apple announces changes for apps in the European Union
I respect your overall point but I think the picture is more nuanced than that. "Computer" as a term is simply unpopular, in favor of something referencing the intended application, as determined by things like the form factor:

Graphing Calculators are computers in every sense, it's hard to find one you can't at least program in a high level language like Basic or Python, and many accept assembly programs - even Texas Instruments models did, before their signing keys were brute forced.

Games consoles too almost invariably run third party code, although they tend not to be end user programmable - no different than an iPhone in that regard, really.

"Feature phones" - pre-smartphone phones with cameras and internet etc - usually had the ability to run Java Midlets without manufacturer blessing, even though you couldn't touch the OS. You could SSH into servers from those!

I think a big problem is that the distinction between "general purpose computer" and "end user programmable general purpose computer" is functionally meaningless when you can't write programs, which is most people. Instead they understand it in a functional context - what is this device for? How does it compare to how such devices usually work? The general purpose CPU inside is an implementation detail, and just because you think of an iPhone as a computer doesn't mean everyone does. They think of it as a "phone".

Microsoft sell locked down PCs today. Secure Boot cannot be disabled, nor new keys enrolled, on Windows PCs that ship with an ARM processor (yes they exist). It's as if Apple decided to lock down Macbooks when they switched to M-series. The only thing keeping PCs "free" is that ARM processors suck at the high end if you're not Apple, so it's seen as acceptable market segmentation. It's purely arbitrary though, just like it's purely arbitrary that you can put Linux on a Macbook but not an iPad despite having the same SoC.

>Camera saw red, you didn't.

But, again, you cannot consider flawed human perception to be the ground truth! Photonically, the red eye is the ground truth. If you were looking through the viewfinder, you should also have seen the red eye effect, if only for an instant. If you didn't, it's only because your eyes were too slow. Or perhaps you weren't looking through the viewfinder at all and therefore not in a position to see the retroreflection, in which case you might as well have been facing the other way for all that counts.

Or consider taking a photo from a moving vehicle. You can't resolve your blind spots with saccades because the scene moves. Your subjective impression is probably that only the thing you're tracking is crisp, and everything else is a vague, blurry mess. Is that what the camera should capture, irrespective of shutter speed?

I think it's clear that culturally we expect photographs to be an indexical trace of genuine photons, not a replication of subjective experience. That is the value they provide over an "artist's impression".

Not "banned" per se, but functionally impossible to run on hardware that's powerful enough to be useful. It's not a stretch to imagine GPU drivers that refuse to run unless installed on a fully "attested" system. We're already there with video games, it's called "anti-cheat". They'll call it something like "AI abuse protection".

That's precisely the point - with AI, "a few geeks" turns into "everyone".
dTal··on Eclipse: The Xiaomi 17 Ultra Confuses the Moon and the Sun
That doesn't seem like a very sharp line (hah). "Abstract geometrical or statistical features like edges" have semantic meaning. An "edge" is just an area of the image with a high derivative, but as soon as you use that information to process it in some way, you are making some implicit assumption about what this statistical feature means - the boundary of an object, a discontinuity in depth, etc.

There is no dividing line between syntax and semantics - semantics is just syntax scaled. Godel proved it, LLMs exploit it.

The layperson also doesn't really consider the result of their smartphone app to be "processed", until they get slapped in the face with it. The layperson's intuition isn't reliable.

Hah. Apple, Microsoft, and Google are all American companies.

What constitutes a "meaningful" difference? If you replace flash-induced red eyes with a more plausible (yet inaccurate) eye color, people are perfectly happy with that, even though the camera indeed saw red photons. They're not happy if you run the exact same algorithm on a photo of someone with genuinely red eyes. It's not always about the "true photons" - the cause of the red eye is relevant, and so is the intent of taking the photo.

"what the human originally taking the photo saw with their naked eye" is a tempting standard, but a misleading one - there might not be a human eye near the camera at all, and at any rate there certainly isn't one co-located with the focal point. And shall we have cameras that render only a few degrees of high resolution color, and have a large-ish blind spot? It's what the human eye sees.

dTal··on Eclipse: The Xiaomi 17 Ultra Confuses the Moon and the Sun
I don't think it's intentional. This behavior is a straightforward consequence of training something on pairs of "real" and "degraded" images. It learns what images look like and does the best it can. Philosophically, replacing the moon with a better moon is no different than any other computational photography technique that uses world knowledge, like reducing red eye from flash by detecting faces, or enhancing blurry text using knowledge of the alphabet.

The problem is philosophical - people are upset by certain types of enhancement error, but not others, and they can't even articulate the difference to themselves, let alone to an AI.

If it's watermarked then it's by definition inauthentic. Watermarking is in-band signal manipulation.

Mmm, software too though. Even those with capable hardware (Macbook Pro for instance) are usually incapable of getting over the hump of assembling an inference framework, agentic harness etc. If that ever becomes easy, watch out! Governments will not appreciate the user/developer dichotomy being blown away.
dTal··on Text AI watermarks will always be trivial to remove
In the short term, governments can suppress free distribution of open weight LLMs. For instance, they could "ask" Hugginface to require an account with a university affiliated email address to download anything. It won't stop you outright, but it will force it underground, slowing everything to a crawl.

In the long run... well, general purpose computing is under threat anyway. Platforms with locked bootloaders and mandatory digital signatures outnumber those that don't. Even on "PCs", the openness is merely a cultural norm observed for a particular market segment[0] by Apple and Microsoft - for they are the only ones with true root keys. Even a brand new motherboard comes with Microsoft signing keys pre-flashed, and you are permitted to enroll your own only by grace. The technical infrastructure to flip a switch and lock it all down is now in place, ready to go at the stroke of a pen. Will you be able to get Llama.cpp from "the app store"? I hazard not. If you think this sounds hyperbolic, look at what is happening to Android.

[0] They don't even segment it the same! Apple segments by "does it have a keyboard", and Microsoft segments it by "does it have a native x86 processor". Apple runs different software on the same basic hardware, Microsoft runs the same basic software on different hardware, but both have created artificially restricted second class computing categories.

To be clear, we agree. The problem is that unless local AIs become "normie friendly" real damn quick, we're gonna lose em, because they're damned inconvenient to power. That is what I fear.
dTal··on Text AI watermarks will always be trivial to remove
Do you not want "normies" to have local AI? Do you believe that your ability to use esoteric software makes you special, makes you immune to law? The days where you can find refuge in running "weird hacker crap" instead of 100% goobermint approved software are numbered because news flash: AI means there are no normies anymore. Anyone can do anything.

No, I will not chill. The war on general purpose computing is gonna get real hot real soon.

Local models enable:

- watermark-free generation

- the stripping of watermarking from the output of SAAS models

Any discussion of watermarking is dead in the water in a world where we are permitted to have these things. I fear for the future.

dTal··on How Claude marks AI-generated content
It's important to distinguish "watermark" from "signature" (and the text/binary distinction is not relevant here):

Signatures are extra data, added out-of-band to the existing data. Out of band data, by definition, is easily detected and stripped, so the utility of a signature is that authoring one requires secret knowledge. Philosophically, the presence of a signature is a kind of authentication, a desirable thing that is hard to grant and easy to revoke (the smallest change to the data renders it invalid).

Now, watermarks: if you flip it round and say you want to glue on a piece of undesirable data - something that represents disauthentication, like a cursed black spot of written-by-LLM - then you want it to resist removal efforts. And now right away you have a hard problem because your sticky data must be in band, or else it is trivially stripped. Not only that, in fact, it has to look enough like real signal that it isn't easily filtered. And on top of that, you can't distort the real signal too much, or people will complain. So you're cornered into doing a kind of steganography - hiding small amounts of information in the entropy, biasing the signal in perceptually plausible ways that are detectable to those in the know. Cartographers add fake streets ("trap streets") to catch plaigiarists - for LLMs, watermarking might take the form of subtly odd word choices.

So you're okay with more and more power held by fewer and fewer people, but balk at all the power held by one person. Where is the line, how will you recognize it, and having done so how will you arrest the trend?
dTal··on They Killed Old Reddit
Old reddit still works for me; however, ten minutes ago I encountered - for the first time ever - a mandatory signup modal on new reddit. The only options for viewing the thread without an account were old reddit, or DOM manipulation. They are definitely moving, and the writing is on the wall - no more anonymous reddit access, going forward.

Looking forward to nitter-style reddit proxies springing up so we can actually read the information freely contributed by decades of unpaid volunteers.

That makes perfect sense - the less you are able to assess "harm" for yourself (because you are not educated or worldly) the more you should rely on external cultural consensus.

dTal··on It's not a fear of "AI communism"; it's a fear of competitive market capitalism
Hardly anybody is talking about the biggest political aspect of open weight LLMs (actually, any LLMs):

Because they instantly and reliably(tm) give you the information you want in the format you want it in, they are going to replace the web search as the dominant mode through which information is disseminated - if, indeed, this hasn't already happened. As such, LLMs are effectively a form of publishing for their training data.

Which means a vicious fight for control over what goes into LLMs, and strong incentives to widely disseminate useful LLMs that encode your structural biases, instead of some adversary's. We already talk about Chinese models that won't talk about Tiananmen Square, but that's eye-rollingly sophomoric compared to what the stakes are now. Imagine a model that subtly discourages entrepreneurship, because its creator doesn't want upstart competitors. All questions of media bias are multiplied incalculably when LLMs are folded into all of society.

I think we need to take LLMs seriously as sovereign projects that are as critical to the democratic experiment as a free press. Funding needs to be nationalized; training needs to be conducted in the open, on open datasets; fine tuning needs to follow democratic principles. Only then will they be fit for purpose for their inevitable structural destiny: arbiters of human opinion.

dTal··on Show HN: Simple algorithm and color space to generate diverse skin tones
Oh goody, an expert in a question I've always wanted to ask.

Once upon a time, I encountered a sort of interactive museum book called "Earthsearch". One of its "exhibits" was a color wheel, made of two spinnable pieces of tinted acetate, that purported to be able to generate any skin tone. I suppose this is three degrees of freedom, since for any position of the two wheels you could access a range of colors around the edge - but the printed page underneath was simply a grayscale gradient, so one degree of freedom was simply luminance.

The book was released in 1994, and was very confident. It even went as far as to encourage the reader to see a doctor, should their skin tone not be achievable! What color model were they using?

That's like inhaling a virus to see if it's contagious. Reading text generated by a model tuned with RLHF is a dangerous pastime. It's all too easy to reach past a human's critical thinking and push the pleasure buttons. Uncanny valley is uncanny for a reason. As social monkeys we instinctively screech danger warnings at each other; AI slop gets the same treatment as an alligator pretending to be a log.
dTal··on Which Odyssey translation wins a blind reading test?
Over the weekend I learned that the new Odyssey film fails a blind watching test; a friend-of-a-friend is sightless, and reports that the entire second half of the film is unintelligible due its lack of dialogue, in favor of a wall of undifferentiated slaughter noises.
