Would celite/carbon vacuum filtration perform well enough to remove photopolymers from isopropyl alcohol?
  • Oh, I missed that it was for 3d printing.

    Maybe an actual chemist will chime in, but I couldn't find any sources about purifying or recycling IPA, at least none that you could do at home. At a guess, maybe a reverse osmosis system without the finest membrane? Like you said, the water and IPA molecules should be smaller than the dyes and resins.

    Maybe also consider washing with the dirty IPA, and just giving a rinse at the end with the clean IPA in order to conserve. Ultimately it sounds like everything I've found is material you're already familiar with, unfortunately.

  • TeamViewer got hacked
  • Anydesk was what I used most recently. They did also have a breach early this year, but they handled it responsibly from what I read.

    If company breaches are unacceptable, there are several selfhosted options, but I haven't tried any so I can't make a recommendation.

  • California to make financial literacy classes a requirement to graduate high school
  • I did that in my high school economics class. I picked a bunch of finance stocks, including Bear Stearns. Then 2008 happened. All I learned was that if you pick individual stocks, you get fucked. For individual investors, the stock market is a scam.

  • TeamViewer got hacked
  • Well this shouldn't be a problem after the last time they got hacked, because they denied it and blamed the users, so everyone switched to a better product. Not to mention the extortionate rate hikes. Right?

  • Server for a boat
  • I would recommend something like a Pi as well, but it looks like you're going to have to take it down to 5v. Maybe a NUC might be better.

    But if you really want 20 TB, you'll need to buy two drives at least 10 TB, and you'll want them to be SSDs for the low power requirement. So that means you'll need a device with two SATA ports, because I don't think anyone makes NVMe drives that big. Oh, and be ready to pay a few thousand for each drive. Also you'll want to keep one drive offline, in an ESD bag in a dry bag. So maybe one will be USB.

    But for real low power, I'd suggest just plain turning it off. Booting doesn't take that long any more. Or maybe suspend to disk, if you can find a system that supports it.

    But overall, I would suggest reevaluating how important these things are to you. Generally, lots of electronics and nomadism don't go together. Have you considered books? I'm sure you can find people to swap with when you're in port.

  • New German citizens required to affirm Israel's right to exist
  • I'm more interested in the inverse: when does colonizing an already-inhabited area turn into a recognized country? Because Israel was created by a stroke of the pen out of Palestinian land. Or is it purely "might makes right"?
