Logan R. Kearsley @gliese1337.bsky.social · 18hApparently /closed loop integral/ and /contour integral/ are in free variation! 110
Logan R. Kearsley @gliese1337.bsky.social · 19hAnd how *does* one pronounce the loop-integral sign...? 100
Logan R. Kearsley @gliese1337.bsky.social · 11/10/2026I wonder how big of a 4D voxel environment I could fit on a GPU if it's compressed as a degree-16 spatial tree. Or a binary partition spatial tree. 000
Logan R. Kearsley @gliese1337.bsky.social · 11/10/2026Xenovision now has a new release that makes pretty false-color pictures! github.com/gliese1337/X... 010
Logan R. Kearsley @gliese1337.bsky.social · 11/10/2026I missed this thing! Where is the new-dad joke? 100
Logan R. Kearsley @gliese1337.bsky.social · 07/10/2026I'm only 37, but I've still got the experience.... 000
Logan R. Kearsley @gliese1337.bsky.social · 07/10/2026Turns out triangulating higher-dimensional polytopes is hard. 010
Logan R. Kearsley @gliese1337.bsky.social · 05/10/2026There are pre-built releases now! github.com/gliese1337/X... So more people have the opportunity to provide feedback now. :)github.comRelease Initial Alpha Release · gliese1337/Xenovision 010
Logan R. Kearsley @gliese1337.bsky.social · 04/10/2026Reading "Lady of Uncanny Charms" is making me really hate Queen Victoria. 000
Logan R. Kearsley @gliese1337.bsky.social · 04/10/2026 And I would also appreciate any development assistance, 'cause I'm just a vision-science enthusiast and I'm sure there's stuff I've missed (even apart from it currently being an alpha-release product with no warranty that it won't randomly crash). 010
Logan R. Kearsley @gliese1337.bsky.social · 04/10/2026Right now, one has to build it themselves, but I hope to get pre-built Windows and Linux releases ready soon. (It should be Mac compatible, but somebody else will have to create the Mac release because I don't have a Mac.) If you are able to run it, I would appreciate user feedback. 110
Logan R. Kearsley @gliese1337.bsky.social · 04/10/2026I just GitHubbed a new alpha-version #worldbuilding tool: github.com/gliese1337/X... It's a tool for modelling arbitrary visual systems (including aliens you make up!) and exploring how they respond to spectral stimuli, so you can compare visual perception across different species.github.comGitHub - gliese1337/Xenovision: Compare different visual systems against arbitrary stimuli.Compare different visual systems against arbitrary stimuli. - gliese1337/Xenovision 130
Logan R. Kearsley @gliese1337.bsky.social · 03/10/2026There is a thing called a "prediction market" which in theory can generate value while rewarding competence. They are sorta-complicated way of paying for expertise. The things currently heavily advertised as "prediction markets" are... not that, and just feed addiction. 010
Logan R. Kearsley @gliese1337.bsky.social · 03/10/2026Now that I have caught up, I think season 3 can be summarized as "What If A Man Was Even Larger?" 000
Logan R. Kearsley @gliese1337.bsky.social · 01/10/2026Also: vast overuse of "real" and "genuine". 130
Logan R. Kearsley @gliese1337.bsky.social · 26/09/2026What should be the equivalent of the Iron Ring for software engineers? 120
Logan R. Kearsley @gliese1337.bsky.social · 26/09/2026I wouldn't. It seems like a straightforward extension of the programmer-to-woodworker pipeline. 011
Logan R. Kearsley @gliese1337.bsky.social · 25/09/2026Not all poster sessions are the same, but generally you will not be giving a talk as much as casually chatting with people filtering by. So, work on the elevator pitch, and having quick answers for whatever you think might be common questions. 120
Logan R. Kearsley @gliese1337.bsky.social · 21/09/2026Speaking as a software engineer myself, it does allow doing some things faster... but it also makes a lot of mistakes, fails when there isn't any public documentation for the relevant domain, and leaves you with a codebase that you probably don't understand in depth and can't debug without it. 001
Logan R. Kearsley @gliese1337.bsky.social · 21/09/2026Blue and green are spectrally adjacent, and covered by a single word in many languages, but I would not call them "close". 110
Logan R. Kearsley @gliese1337.bsky.social · 21/09/2026Not a joke! There really are blue pumpkins. And red ones, and yellow ones, and white ones. The red ones tend to be really watery. 210

Logan R. Kearsley @gliese1337.bsky.social · 20/09/2026Blue ones are the best for baking, in my experience. 100
Logan R. Kearsley @gliese1337.bsky.social · 17/09/2026OK, so you don't actually understand dualism vs. materialism. Got it. 100
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Fun work quote: "We don't need to beat the enemy to everything having to do with AI; if they all kill themselves with AI, we can hold back on that." 040
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026If you assume that replicating the physical substrate of some complex system *won't* result in a new system with the same behavior, *that* is implicitly dualist. 100
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026That's a weird definition of dualism that neither seems very useful, nor like it would match most people's intuition. I am assuming that minds are encoded in the state of a physical substrate. A dualist would posit that there is a second, non-material thing. 200
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Who ever claimed that reducing a neuron yo a zero or one would provide sufficient detail? There's an astronomical gap between "the operation of human brains probably doesn't rely on every detail of its quantum state" and "we only need one bit per neuron". That's just ludicrous. 100
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Hence, it should be easy for a simulation to trick the senses. 000
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026If you assume that a brain simulation will only produce acceptable results if you simulate the environment around the brain as well, then yeah, an acceptable environmental simulation would be one that successfully replicates sensory experience. 100
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026What? How do you get *that* from what I wrote? Physical systems don't have to work like a computer to be simulated on a computer. And simulating a dead brain would just leave you with a simulation of a dead brain, not magically turn into a living one. 000
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Only if 1) you assume that you need to capture the entire quantum state, and 2) you want to do it non-destructively. But if the classical states are a good enough snapshot, or you're fine with move semantics instead of copy, then it's "just" engineering. 100
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Huh. I would've thought just the opposite; you can't upload a soul, but maybe you could record the state of all of your neurons and simulate their activity in a computer. 110
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Ah, well that would be embarrassing for him, then. 100
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026For certain values of "like". It is, indeed, a non-dualist argument, but not one that I find at all *convincing*. 010
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Yes. So if that's the strongest non-dualist argument available, I see no reason to find Will's claim in this case "embarrassing". 110
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026So the argument is just that no simulation at less than atomic resolution could be good enough? That seems implausible. You *definitely* don't need anything near atomic resolution to replicate the environment well enough to trick human senses. 340
Logan R. Kearsley @gliese1337.bsky.social · 16/09/2026Is there any non-dualist argument that some process in the brain *can't* in principle be simulated on a computer? 140
Logan R. Kearsley @gliese1337.bsky.social · 13/09/2026Any progress on this that I missed in the last year? 122

Logan R. Kearsley @gliese1337.bsky.social · 11/09/2026Yeah, I'd say "the second Friday of every month". And to get the other interpretation, "every second Friday" or "every other Friday", with no mention of months. 040
Logan R. Kearsley @gliese1337.bsky.social · 11/09/2026Maybe? But one interpretation is sufficiently obvious that I have to really pay attention to make the other one work. 110
