krackers··on Neural networks are clean
The way he describes the model of neural nets almost reminds me of a decision tree, with the positive/negative poles and stuff. There's another quote from the article about the "textbook" intuition of convnets

>neurons generalize, work together, and build abstractions over layers. Somewhere along the way we overcomplicated that picture, but looking harder brought it back.

and it does seem that if what the article claims is true, then it really is that simple. To clssify e.g. fruit they first detect curves/shape, then the neurons downstream of say the "circle" detector may distinguish based on color, then the ones downstream of a specific color distinguish by texture, and so on. By the end, what you have are neurons that activate only on very specific combination of features, which map to each fruit.

It's about as difficult as describing vectors in math. Vectors aren't really "little arrows" or "things with magnitude and direction" (because then functions wouldn't count), I think there's a similarly cryptic saying that "a vector is just an element of a vector space" or "a tensor is anything that transforms like a tensor".

In both cases what they really are is an abstract concept defined by things that satisfy some definitions, but in practice it's easier to just look at a few concrete examples like Maybe.

krackers··on Furifont, a Japanese font that shows furigana
That's surprising. I'd have thought that a multimodal LLM like openai's would "just work", at the very least enough to generate enough data to distill down to a simpler model.

This only works of course if the game is actually fair, and you have infinite money reserves.

You can run LLMs inside the shaping engine, so maybe you can use more advanced segmenting and transliteration algorithms? https://fuglede.github.io/llama.ttf/
krackers··on Two-Stack Sliding-Window Aggregation
Hm that's clever. You're basically taking the classic "queue using two stacks" algorithm but then replacing each stack with a min-stack (like in that leetcode problem where each element also tracks the aggregate of all elements below it) to get a "min queue".

And then unlike the usual monotone queue for sliding max/min, this works for any monoid since you're never comparing two elements.

krackers··on Do dentists know what they're doing?
SDF is good, but P11-4 Peptide is even better if cavities haven't reached the dentin yet. No idea why you can't buy products with it OTC, it's not like it's hard to apply.
krackers··on Do dentists know what they're doing?
> It alternates which nostril feels blocked, sometimes both feel blocked.

To some minor extent this is normal, https://en.wikipedia.org/wiki/Nasal_cycle . Or at least the alternation itself is probably not the issue.

krackers··on Is 'Attention' the Essence of Intelligence?
Aren't all of these (including convolution) specific instances of Graph Neural Networks?

I don't have any specific experience in ML but I always liked the formalism presented in https://www.youtube.com/watch?v=J1YCdVogd14 as a way to unify everything

>drops the positional encodings after pretraining,

I thought with NoPE schemes you don't even need it during pretraining

Given the causal mask and the way attention works LLMs can implicitly propagate a signal for ordering

krackers··on The Dock on Mac, from OS 10 to macOS 27
Isn't dock also responsible for mission control? There was a trick to set an extremely long show-timeout to effectively permanently hide the dock, if that works it's probably better.
krackers··on Auto Research: Integer multiplication below n log n
>instead of costs scaling with the size/precision of the number

But isn't the assumption that arithmetic is "atomic" standard in TCS? Costs do scale with the bit length, presumably they aren't assuming that addition is "constant time" with respect to # of bits (which would defeat the whole point of the exercise).

Maybe I'm missing something, but none of the things mentioned in that blogpost seem particularly "surprising" to me, most of it focuses on the fact that computational models used in TCS don't align with the real-world model of computers, but that seems like something you learn in day 1 of algorithm analysis? If you want something closer to real-world you'd use word ram model.

krackers··on Auto Research: Integer multiplication below n log n
Is there any good writeup yet of intuitively where the speedup comes from? E.g. with fast fourier transform you can see that there's a lot of symmetry & recomputation in the Vandermonde matrix, so that's where the speed up comes from.

krackers··on Anthropic is out with new nonsense about Claude
I find it amazing that people are suddenly so sure of things that philosophers have been grappling with for centuries, and the way people have reinvented notions of "soul" now that outright religious language is passé

krackers··on AnyPS5: Port PS5 binaries to PC without emulation (87% system libraries mapped)
A trivial scheme would be to distribute some shared secret key in a new update, and require it to be supplied back on connections to Sony's servers. In order to extract that key in order to replay it from an older firmware, you'd need to have root on the new firmware.

TCC throws up vista-style warning prompts everywhere, so to bypass them he opened up remote desktop so he could manually dismiss them, which then got exploited via a recent pre-auth bug in ARD.

If the TCC prompts could be dismissable some other way (e.g. via CLI with root permission) presumably he wouldn't have resorted to such measures. I sort of see the point, the lesson from Vista is that if you put up annoying obstacles people are going to the easiest workaround, bulldozing over them rather than putting up with them. People will end up disabling SIP or poking more hole if they don't have an easy way to bypass TCC stuff.

So an encoder-only model with a classifier trained on the heads or something? DeepSeek recently switched to an encoder-decoder architecture in an attempt to get the best of both worlds (fast prefill while preserving generation capability), I wonder if that might be the future?

I think that implies mv3 does support it. Seeing as it can inject scripts, I don't see why it wouldn't be able to.
