If the AMOC shuts down, all bets are off.

I mean I'm about a billion dollars short of being a billionaire, and I don't know how to live without exploiting labor either. I can't farm, I can't hunt, I can't identify edible berries, roots, and mushrooms, I can't sew beyond fixing a button. I know a lot about mechanisms, but it's far from clear to me I could do anything useful in that field once the electricity is out, let alone once source metal starts getting hard to find. Everything would get so much harder so quickly. Hell, I don't even know how to dig a latrine that'll prevent the water supply from being contaminated, assuming we can find a water supply. (On the plus side, sources of pollution in water supplies should start to fall apart pretty fast.)

I dunno. I just think everyone thinking about the collapse wildly underestimates how hard everything will be. I can't really picture my sorry ass lasting long at all.

We coulda had Local Loop Unbundling all this time.

I mean, redraw this graph as "happiness" vs "year of birth" and it'll look way less optimistic!

So is it being used as slang outside the context of describing people as non-Jewish? I grew up in Skokie, IL, so I was familiar with the yiddish term, but I haven't heard this new usage. Are non-jewish kids online using "goyim" to refer to outsiders of some other in-group?

To quote professor Farnsworth, "No, no, no one's saying that. But I'm certainly thinking it loudly."

They do very occasionally blunder into something that has merits. Like, they rescheduled marijuana, and they're fast-tracking research on therapeutic psilocybin and MDMA. Those are positive things, broadly speaking. Removing the tax on tipped workers was also helpful for some working-class people.

I can't think of anything else off the top of my head, but part of that is probably availability bias: the vaguely positive stuff that they do is a lot less emotionally charged, and therefore less memorable, than the wildly awful stuff they also constantly do.

I thought of another one. This is an odd one, because I think the dev is actually quite well known: it's Yahtzee Croshaw, formerly of Zero Punctuation and now of Fully Ramblomatic. He's made a number of games over the years, but one that almost nobody ever mentions anymore is Poacher. (Note: link is to Archive.org rather than Steam; I don't think the game is available on Steam.) I didn't actually beat this one, as it ramps up quite a bit in difficulty as it goes on, but the basic controls and whatnot are very nice, and the humor is great. Here's Wot Rock, Paper, Shotgun Thought about it, since it's a bit of a faff to actually install at this point and Archive doesn't offer reviews and whatnot.

The catch is that it's "unlimited" in that sense that the mobile companies have made people accept now, i.e., deprioritized. I'm on Visible, which is Verizon's MVNO; my plan has unlimited deprioritized everything, and it's $25/mo, with $5/mo discount for the first two years so I'm actually paying $20/mo for now. It's mostly good enough for my purposes; I'm usually on Wifi anyway. When I was leaving a protest and turned my phone back on, I couldn't get enough access to check the bus schedule or text my family, so that was frustrating; dense crowds are a problem. But I was previously paying like $130/mo for Verizon, so it's more than worth putting up with. I got some mesh radios for emergency comms.

I've recommended this before, so it's possible people will have heard of this from me, but Gateways by Smudged Cat Games is pretty great. It's a puzzle platformer but it gets very, very complicated as you go on, especially once you unlock the ability to use all the different mechanics at once. It's a pretty smooth learning curve up to that point, though.

Moire/Vernier Radius Gauge (www.printables.com)
submitted 1 year ago* (last edited 1 year ago) by monotremata@lemmy.ca to c/3dprinting@lemmy.world
 

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.

 

Bear with me for a moment, because I'm not sure how to describe this problem without just describing a part I'm trying to print.

I was designing a part today, and it's basically a box; for various reasons I wanted to print it with all the sides flat on the print bed, but have bridges between the sides and the bottom to act as living hinges so it would be easy to fold into shape after it came off the bed. But when I got it into PrusaSlicer, by default, Prusa slices all bridges in a single uniform direction--which on this print meant that two of the bridges were across the shortest distance, and the other two were parallel to the gap they were supposed to span. Which, y'know, is obviously not a good way to try to bridge the gap.

I was able to manually adjust the bridge direction to fix this, but I'm kinda surprised that the slicer doesn't automatically choose paths for bridging gaps to try to make them as printable as possible. I don't remember having this issue in the past, but I haven't designed with bridges in quite a while--it's possible that I've just never noticed before, or it could be that a previous slicer (I used to use Cura) or previous version of PrusaSlicer did this differently.

Is there a term for this? Are there slicers that do a better job of it? Is there an open feature request about this?

Basically just wondering if anyone has insight into this, or any suggestions for reading on the subject.

Thanks!
