  • It depends on your specific case, of course. That 0.4mm is indeed a good rule of thumb. But also, assuming you’re dealing with FFF-printed parts, generally if the two parts slide together along the layer lines, it’ll feel just a little looser than if they slide together perpendicular to layer lines. That’s just due to the ribbed texture inherent to FFF printing. Though printing at smaller layer heights will reduce that effect and also make the parts fit just a little looser over all.

    Aside from that, probably the best advice I can give is:

    1. Measure/calibrate for dimensional accuracy. [Here]'s a random article on the topic that looks pretty good to me.
    2. Prototype. Print once, if it doesn’t fit right, adjust the model(s) and print again. Filament is pretty cheap, really. Also, depending on your situation, you might benefit from doing quick test prints just to see how well it fits. If the whole print is going to take 8 hours but by spending 30 minutes printing just part of the final product you can prove you’ve got the dimensions right, it’s probably worth it to do the 30 minute print.
    3. Use elasticity to your advantage. Make latches or attachments that snap into place. That’s useful whether the parts are meant to go together once and never come apart or connect and disconnect repeatedly. Another use for elasticity is if you need two arms of one piece to friction-grip another rectangulat piece, angle the arms inward just a degree or two. One word of caution, though. It can be really easy to overestimate the flexibility of PLA. I’ve ended up once or twice with some pretty hard to open latches.







  • I had some hands-on computer repair training at a private school once. One old machine wouldn’t boot, complaining that it couldn’t find the keyboard which was plugged into it. I unplugged it while the computer was on. At the time, unplugging a keyboard while the computer was on was… not a good thing. There was a little curl of smoke, a scorch mark on the motherboard, and a sustained tone from the chassis and that computer breathed its last.

    Later, in college, I used the “net send” command on random people in open labs just to watch how confused they got.


  • Oh I’m with you. There used to be (though I haven’t been able to find any lately) Tor web gateways that would let you visit a tor site without having to run Tor or Tor Browser yourself. They don’t protect your identity when you use them the way using Tor Browser protects your identity, but they could be used. And some onion sites still come up as results when you search DDG for something like “Hidden Wiki site:onion.pet”. The result doesn’t link you to the .onion address, but to a .onion.pet address that takes you to the same page/site.

    As far as Tor and speeds, I think Tor imposes very large latencies (that is, it takes a few seconds to get a download started), which is more what you’re experiencing when you notice sites “being slow” when browsing through Tor. But bandwidth isn’t affected all that much.

    One caveat, though. When downloading through Tor, your request is being proxied through a chain of proxies. If any one of those is slow or purposefully limits speeds, that will limit your bandwidth. That’s a problem, maybe 30% of the time or so. But there are commands you can use to tell Tor to “please select a different route.” After doing that once or twice, you’ll generally get a decently fast “circuit.”

    Just as a test, I downloaded the latest Arch Linux ISO (which is 853MB in size) from here both via Tor and directly. Direct took 7 minutes 36.324 seconds for an average speed of 1.869MB/s. Tor took 9 minutes 26.627 seconds for an average speed of 1.505MB/s. In short, a pretty moderate difference in speed.

    And, yes, this is a highly unscientific, n=1 test, but I think it’s pretty well in line with what I’ve seen in the past.



  • Closest thing I’ve found was /r/OpenDirectories on the site that shall not be named. Which is to say, no there’s not really any such thing as “Pirate Bay but for direct downloads.” At least not that I’ve found.

    Pirate Bay but for direct downloads does seem like something that might be able to thrive on the dark web, though, doesn’t it? I wonder why something like that hasn’t become a thing and gotten big.

    I suppose some site that just acts like a searchable directory of links to IPFS could be used in combination with IPFS web adapter sites. But I haven’t found anything like that.





  • Mine was pretty spontaneous. I was studying psychedelics at the time (just because they’re fascinating) but I’ve never done any before or since.

    It was… hard to describe. It lasted several days at least, but my sense of time was greatly altered and it’s hard to say how long exactly. I remember feeling like my mind wasn’t fighting against itself the way it usually did. It felt like everything I did, my whole brain was all working/pulling in the same direction. Pretty much all I wanted to do was meditate for hours on end, and doing so was a wild experience with some very interesting visuals. I also came to some revelations about the nature of reality. (Though looking back, those revelations were the logical conclusion of several beliefs I had held before this experience. I think this experience just brought those multiple unrelated beliefs together and crystalized them into one cohesive worldview.) I did experience some synesthesia during the experience as well. The kind wherein seeing somebody else experience something, you feel it in your own body. I was watching a dancer on TV and feeling the proprioceptive feelings I imagined she was feeling.

    Edit: I should add that it never really “ended.” It tapered off over time until I was (in some ways) back to normal, but I couldn’t identify really when I was back to normal. It was more like asymptotically approaching normal. And, I’ll also say that in other ways, I’m still changed by that experience. And only for the better.



  • Nazis aren’t people who say some anti-semitic stuff sometimes. Nazis hurt and kill people.

    Agreed. Wasn’t trying to say otherwise. But I’d think recovering nazis are frequently “people who say some anti-semitic stuff sometimes.” I’ve known people who have deconverted from both mainstream religions and cults who have needed support in the transition out, and those folks were “kindof brainwashed but working on it.” And I don’t think nazi groups are entirely dissimilar from cults.

    I don’t remember which episode specifically, but I remember Ian Danskin (“Innuendo Studios” on YouTube and creator of “The Alt-Right Playbook” series) making some points about how it’s good to have spaces meant for people who are “kindof a nazi, but working on it.” (He also said those spaces need to be kept well away from safe spaces for marginalized groups, which of course makes sense.)


  • These programs you’re referring to are voluntary, right?

    So, the folks who would be against such programs on that basis think that if a(n arguably former) nazi enters the group not yet fully free of the bigotry they’ve taken concrete steps to overcome and says something, say, anti-semitic, if the program doesn’t kick them out on a zero-tolerance policy, then the program is supporting (or at least insufficiently condemning) anti-semitism?

    Edit: on rereading, I get the feeling you’re saying something more like some people think having anything to do with (even recovering) nazis is tacit complicity or something.


  • The only potential problems I can see with that:

    • If it’s on carpet or a rug, that could potentially block vents or get tangled in a belt.
    • If it’s in a high-traffic area, it might be kicked or tripped over.
    • If it’s too close to a (particularly cold) vent and not in an enclosure, that could cause some warping of parts during print.

    Those are really the only concerns I can think of. If you choose a spot on the floor where none of those are an issue, I’d think it should work as well on the floor as on a desk or table.
