A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

a growing block of our already wildly disaffected voters are stupid, ugly, and nihilistic. i enjoy hectoring and marginalizing them before and after every "the most important election in history"

Mr President Sir without NHANES the US will lose the trade war and become a net importer of observational studies

Beth S Linas, PhD, MHS @bethlinas.bsky.social · 19h

I can’t begin to tell you how much research, policy, and programming revolve around the use of NHANES data. Again, you think these lay offs don’t affect you? Think again- money gets allocated based, in part, on what these data show. This is stunning

CDC team running top survey on health and nutrition is laid off

NHANES has collected data on eating patterns, diabetes, and other common diseases for decades. The CDC team that runs it has been fired.

Fundamentally I think this is the important mental image… an artificial neural network is roughly a container that can hold a shape of certain dimensions.

“Training” and whatnot boil down to different ways to methodically deform the shape

rev. howard arson @theophite.bsky.social · 2d

you can think of a LLM as a shape in high-dimensional space. this is unintuitive. how is a model a shape? the same way as a graph of the relationship between height and weight is a shape. the vast majority of the variables represented in this space are composites of other variables.

the actual story here, which the media never talks about, is that police in this country have become a discrete right-wing political operation. the story isn't about cops leaving (they're lying about that), it's about the police trying to exert influence over elections.

It’s a good name because it forces you to say dumb stuff in opposition to it. No one needed a King to get a paycheck before.

Ethan Soutar-Rau @ethansr.bsky.social · 3d

By analogy to LLMs, that would mean something like reading in tokens that are not in the input.

But no one uses it like that. They use it for the model outputting tokens which contain facts that the LLM doesn’t have.

This is a completely different problem! Confabulation? I dunno.

I really hate the use of “hallucination“ in the AI community. It obscures the nature of the problem.

Perception *is* constructed, but it’s usually grounded in reference to the senses. If it’s not, and you perceive something you don’t sense then you might be hallucinating.

☁️ Ascended NPC Alex ☁️ @lastnpcalex.agency · 3d

that is, in some way, aren't we all hallucinating? the sense that my sensorium happens "at the same time" is simply false. sound and sight and touch reaching my brain at different times. all experience a hallucination... and yet, that isn't useful for understanding how we are good at prediction!

I will say that the federal bureaucracy has worked as a sort of ark that has carried within it an optimistic mode of American life.

jamelle @jamellebouie.net · 3d

a key thing about vought — and all of these guys — is that they have a totally top down and hierarchical vision of the world. they believe that the cultural changes they hate can be turned off by destroying the federal government because they can’t imagine that they emerged bottom-up in society

Thomas Zimmer @thomaszimmer.bsky.social · 3d

What he’s railing against is a profound shift in culture, status… He’s obsessed with the idea that America is controlled by a leftist “ruling elite” - but “elite” isn’t defined socio-economically or by political power, it means something like: Getting to define “real America” and who gets to belong.

Ethan Soutar-Rau @ethansr.bsky.social · 3d

I wonder if this effect is so strong In US because both parties have policy platforms which simply won’t work as desired.

input buffers are already a sort of transparent proto version of this.

I was thinking the other day of making a fighting game where one could explicitly hold the input buffer and then execute the sequence when you desired.

There’s something worth pointing out here that Denmark doesn’t really have any incredibly dense parts. So the average is the same, but the median experience is pretty different.

Oh The Urbanity! @ohtheurbanity.bsky.social · 4d

Fun fact: despite the enormous land mass, the population-weighted density of Canada — basically the density experienced by the average person — is the same as Denmark and close to the Netherlands.

Canada and Denmark are 3,000 people per km², while the Netherlands is 3,400/km².

One thing I am wondering if we’ll see is a kinda judicial nullification where lower courts act as if Supreme Court rulings don’t apply in their jurisdiction for various reasons.

(Which is sort of the converse of the Supreme Court saying district courts cant make nation wide injunctions)

Jake Grumbach @jakemgrumbach.bsky.social · 4d

District court judges, appointed by presidents from Reagan to Biden (including Trump I), seem to understand the assignment more than most law firms. This is curious because the data shows that lawyers as a whole are more liberal on average than federal judges

Jon Seidel @jonseidel.bsky.social · 6d

Perry asks directly whether the feds started the alleged violence in Chicago.

She asks whether it matters if the inability to execute the law was "caused by the federal agents."

the move to internalize customs revenue within the executive was telegraphed even before the previous near shutdown.

If there had been resistance then, the money would not have been collected yet.

As is, now it has and everything becomes a procedural question.

Mike Black @mikeblack114.bsky.social · 4d

So the Dems need to be clear again that any FMer carrying out direction to implement mil paychecks in the absence of appropriations will be subject to anti-deficiency act criminal penalties, because to be clear even with the reconciliation slush fund BS there is no way to legally so this, period
