  • No. As noted, it’s a rivet. It was originally a straight piece of metal rod with a cap (visible in the top image) at one end, inserted into the joint, then the other end deformed with a rivet tool to create a lip on the end (lower image) so it stays in place.

    To remove it, use a drill bit about the same diameter as the rivet shaft, and drill it out from the end in the lower image. You usually only have to drill less than a millimeter before the lip breaks free, and you can pull out the rest of the rivet. The trick here is that the rivet is probably hardened steel, that means it’ll take a carbide drill bit, and some time.

    This is obviously a destructive procedure for the rivet, and then you need special tools to put in another. It might be possible to replace with a screw, but it won’t be quite the same.




  • More research is always good, as it can deepen our understanding, but the basic outline of what’s going on is already known. A lot of people just don’t want to believe it, because we’re all stuck on the metaphor that we’re all captains of the ship inside our own heads. You see it in this thread; people want to blame non-voters, as if millions of people all had perfect information and all made decisions based upon it through conscious reasoning. Because they’re just—I dunno—bad people? (Which is a completely bonkers belief when you start to dig into it.)

    Actually, neuroscience tells us that consciousness doesn’t really exist, except as an emergent phenomenon of sensory experience. Brain scans show that thoughts, feelings, and decisions occur before we’re consciously aware of them; the conscious mind is basically a rationalization machine, inventing narratives about why we did a thing or felt a certain way, only after the fact. And, it’s notoriously bad at it. (The Misattribution of Arousal is one of the classic examples.) So, if you can affect the way that somebody’s brain works, you can in many ways control what the they think and feel.

    And that’s exactly what authoritarian demagogues do.



  • Thanks. That is what I’d expect, and highlights the disconnect I saw in this comment chain: I think what some other folks were trying (less-than-artfully) to say is that there’s a difference between what one might expect case-insensitive means as a computer programmer, and what one might expect case-insensitive to mean in human language. All three of those should be the same filename in fr_FR locale, since some French speakers consider diacritical marks to be optional in upper case. While that might be an edge case, it does exist. English is even worse, with a number of diacritical marks that are completely optional, but may be used to aid legibility, e.g. café, naïve, coöperation. (Whether that quirk is obvious or not, or whether it outweighs any utility of case-insensitivity is not something that I have a strong opinion on, though.)
