Does anyone know of any code laying around the net that distributes points on a mesh in a blue noise distribution?
A student intern i work with is looking for this. It's tempting to write it, but im also kinda swamped :X

@mmby@mastodon.social avatar

@demofox I think the task may be harder than one thinks, since you cannot make continuous maps of any arbitrary 3d surface that are isometric

what do you do between the cuts? if you cannot work with a parameterization, you have to work locally on the surface

My comments in TechCrunch. Google/Android AI feature to detect scams-calls is useful. It's client-side so privacy guaranteed. However, once client-side scanning and control is is baked into software infrastructure, nobody knows where it may lead. Censorship? Technology control of societies? Let's just be careful here. https://techcrunch.com/2024/05/15/googles-call-scanning-ai-could-dial-up-censorship-by-default-privacy-experts-warn/

@LukaszOlejnik just because the classification runs on-device doesn't mean the classification result can't be sent back home - sure, less data over all but a cynic might call it "surveillance computing on the edge"

Psst smart pointers still have to have their references cleared, else they leak just like regular pointers.

@demofox weak_ptr can 'let go' (as opposed to have shared_ptr in two places and having to coordinate) but I've rarely seen it talked about in any sort of tutorial on smart pointers

I managed to fix the GPU hanging issues but the "optimized" BVH traversal in compute shader still works slower than the unoptimized one 😭

In other news, I tried the Möller–Trumbore ray-triangle intersection algorithm, and it too turned out to be a bit slower than my extremely direct algorithm that just solves a linear system:

@lisyarus I'm not sure but could it be the branching in the Möller-Trumbore?

I seem to remember reading that all shader branches may get executed so the early-outs might not do much.

: The "Ashcroft/Mermin Project"
I will try to (likely very slowly) go through the classic textbook "Solid State Physics" by Ashcroft and Mermin and make one or more animation/visualization per chapter.
This will (hopefully) help people digest the topic and/or be useful to lecturers who are teaching about it. As with all my animations, feel free to use them.
The idea is that the animations are a companion to the book, so I will give only very brief explanations here.

It's pretty foolish to let your platform be spammed like that, some people are auto-uploading dozens a day. I think even the prompting is automated. And it's just so… boring . And it barely gets any engagement anyhow.

WHERE THE WEB IS GOING: The convergence of LLMs and web advertising will lead to "ads" consisting of several hundred gigabytes of javascript containing a (weighted) neural network designed to generate unique per-user video advertisements—generated on your computer at your expense to ensure the imagery is unique and evades AI-based ad-blockers.

"AI spam" is an entire AI, squatting on your CPU and making it glow dull red as it works out how to capture your attention.

Welcome to the spamularity.

@cstross since the bottleneck for LLM companies is data, as I understand it, I feel recording people's behavior will become more and more pervasive, in effect an always-on livestream of what you're doing, be it outside or on a device - text, image and video on platforms can only cover so much

jsut like google TOS, this access will be a requirement for access to services built on that data

@futurebird prompted by your post I just had a look at the German etymology of the word Ameise

What's also interesting about the German word is that a pallet jack is colloquially called 'Ameise' on the shop floor in any company I've worked at, since an older German company made pallet jacks under the name:

So long before LLMs were cool, I spent literally thousands of hours training and generating with language models going back to vanilla recursive ANNs. What I was obsessed with was the uncanny valley where they would produce text that was grammatically and syntactically correct but no human would EVER produce words like that. The vastness of linguistic latent space that is terrifying and hilarious.

LLMs still have these moments too, and my eyes are finally adjusting to them to where they are plain as day. A lot of whats cool about uncanny valley text is the sense of "I dont know whats wrong about that, I just know its wrong," so its hard to articulate rules, but heres one: eager presumption of an impossible theory of mind for the reader.

Natural writing is a dialogue with a presumed reader, and that requires gaming out how they are reacting to what youre writing. The signifiers of appealing to your reader are extremely common - hedging, prefacing, literally saying "you might be thinking," etc., so are common in the training set, but LLMs eagerly signify appeal to reader when it makes no sense.

Here are two examples from an obvious LLM scamblog article about styles of cowboy boots. On the first, I certainly wasnt worrying about the continued existence of brown boots given the macro-scale norm of brown boots, but it makes perfect syntactic sense when constructing a list of colors to say {there are colors, but dont worry there are non colors too}. In the second, I may have been wondering what defined the style of boot, but I certainly wasnt wondering what the term buckaroo meant.

These are local prediction errors: the text is extremely logical - if you had no idea what culture was outside of the prior few hundred words.

@jonny I remember someone taking two GPT-3s(? I think) and making them talk to each other with the prompt to make communication as efficient as possible between two 'AI's

people were amazed that the GPTs bounced cryptic messages off each other with weird quasi-pseudocode embedded but if you factor in all the fanfiction, it was likely a mash of third-rate scifi examples of 'AI' technobabble

Abandoned farm. I learned two fun facts on this trip. The first is that stinging nettles were mixed in with the weeds surrounding the barn. The second fun fact is that even if you just brush against them, stinging nettles are surprisingly painful. Anyway, here's more abandoned houses and farms if you are interested: https://www.abandonedamerica.us/abandoned-homes

@AbandonedAmerica Australia has a stinging nettle from hell:
https://en.wikipedia.org/wiki/Dendrocnide_moroides

"The stinging persisted for two years and recurred every time I had a cold shower...There's nothing to rival it; it's ten times worse than anything else."

Even dried for years, the plant nettles will still cause reactions, the shed hairs will form a dust when disturbed.

How do we know that the 'super-rich' are getting worried that may prompt social upheavals that threaten their wealth?

A recent poll suggests around three-quarters of them support 'higher taxes on wealth to help address the cost of living crisis & improve public services'.

Well, for the most part they have the ear of Govt.s so its time for them to stop the virtue signalling & actually act. Whether they have the stomach for a new Left is another Q.

The boom in LLMs is going to hollow out a number of knowledge-worker industries — for example, writing boilerplate code or technical documentation

Not because it does it well but because the flacks can sell upper management on the idea that it can do it at all, as @pluralistic recently pointed out

This sale is a pig-in-a-poke, and the winning move is to not be holding the bag when the actual code or documentation is found to be terrible
