Talkie? Is that you?

    The product is a bag of Jack Links / Doritos Nacho Cheese Flavored Beef Jerky. Highly processed beef, highly processed cheese, doubly highly branded. It just feels like late stage capitalism. Both of these brands already make low-nutritional-value foods with addictive, hyperpalatable attributes, and here they're trying to hybridize into some kind of abomination.

    People just feel like the world is off its axis, you know?

    10base2, or ThinNet, were the English names of that kind of networking. We had a mix of that and 10baseT (rj45) when I was first in college. 10baseT was significantly better, in that fewer machines had to physical share the same bus wires.

    I'm not sure what video you're referring to, though.

    That's exactly the distinction I was making. The person I was replying to said "Imagine believing that they need “AI” to record us." I was clarifying that this isn't the AI we hear so much about that requires huge datacenters; it's the kind of simple, embedded, "edge" AI that you can do with whatever microcontroller you have lying around.

    These TVs don't incorporate enough power to do any kind of serious LLM. The "AI" they're referring to here is likely an embedded speech-to-text engine. And that probably is pretty necessary for this--it would take too much data to send actual recordings to Samsung, but text transcripts are tiny and easier to search and index. It's easy to forget, but reliable speech-to-text has been around less than 20 years, and the tiny ones that can run on embedded chips are even newer.

    I dunno. I think you want to make efforts to get at what the voters actually want, and that means making some allowances for voters being, y'know, fallible humans.

    Have a look at the "butterfly ballot" used in Florida in the in 2000 presidential election:

    Butterfly Ballot for the 2000 Florida presidential election

    Now, it's pretty clear to me, looking at that, that the top hole is a vote for George W Bush, the hole below that is a vote for Pat Buchanan, and the hole below that is a vote for Al Gore. But it's also obvious to me how a voter could think that the second hole is for Gore, as the listing on the left side of the ballot has Gore listed just below Bush. I wouldn't make that mistake here, but it's plausible to me that people would. And indeed, people did. Buchanan got a LOT more votes than his polling would lead you to expect; and while this was still a small number of overall voters, it was more voters than the margin in multiple counties, including Miami-Dade. And Florida had enough electors, and the national election was close enough, that how Florida went decided how the whole country went. That is, these few people (less than 2000) making this mistake may have been a deciding factor in the national election of George W. Bush.

    So while, yes, it's the vote they cast, and if they can't handle something as simple as voting then maybe that's on them... it's not like it doesn't matter. We should want the outcome of the election to reflect the will of the voters, and so it makes sense to make some effort to make it easy for them to vote for the person they actually want.

    Elections aren't usually close enough for this kind of thing to matter. But it sucks when it does.

  • Moire/Vernier Radius Gauge (www.printables.com)
     

    I previously posted this on Reddit, since it reaches more people there (and I didn't want to post everywhere at once, as it makes it harder to keep up with the comments). Sorry about that.

    This is a tool for measuring the radius of a circle or fillet from the outside; it uses a moire pattern of slots and lines to enable a direct reading of the values from a vernier scale.

    A video of a broken-open version makes it a little easier to see how the moire and vernier features operate: https://i.imgur.com/Ku2nBkq.mp4

    More photos of a slightly earlier version are here, including the tool being used for actual readings: https://imgur.com/gallery/moire-vernier-radius-gauge-design-3d-printing-ajy0GBg

    I was inspired by this post: https://makerworld.com/en/models/1505553-adjustable-chamfer-gauge#profileId-1575605

    which is a gauge which measures chamfers using a sliding probe. The same user had also posted a radius gauge, which worked similarly, but it was much larger, using gears and two racks in it to amplify the motion, which I didn't initially understand. I asked about it, and he pointed out that, because of the geometry of the probing, the slider only moves a small proportion of the length of the actual radius being measured--about (sqrt(2)-1), or 0.414mm per mm of radius. Since we're drawing the marks with a 0.4mm nozzle, it's not really possible to make marks that close together and still have them readable.

    So I thought, I bet you could fix that with a vernier scale. And then I had several thoughts all at once--that a lot of people are kind of scared off by vernier scales, and also that I bet you could fix that with 3d printing using the relationship between moire patterns and vernier scales. I don't think I've seen this done before, but it probably wasn't really practical before 3d printing. Arguably it's not entirely practical now, as the deep slots and parallax effects can make it a little hard to actually see the markings. But it was a fun experiment, and I think the result is eye-catching enough that it's probably got some educational value in getting people to actually think about how it is that vernier scales work. (It might even have educational value for things like number theory...e.g., it's important that the vernier factor involve relatively prime numbers, in this case 9 and 10. Can you see why?)

    Anyway, hope folks here find it interesting too.
