If a planet was completely covered in water, wouldn't it all be freshwater?
  • In freeze desalination, the initial ice crystals before it freezes solid are pure water; you mostly freeze a volume of saltwater into slush, strain out the ice, and discard the liquid (which will be brine; higher in salt than your initial water).

    Probably not super efficient, and probably needs multiple steps, but I dunno. Somewhere where the ambient temperature is below freezing, but geothermal is available, it could work at scale, but if you have to refrigerate, you're probably better off with regular distillation

  • Drug overdose deaths fall for 6 months straight as officials wonder what's working
  • It's still not likely to be common negligence; weed scales and powder scales are generally different scales (different levels of precision, and different maximum weights), unless you're dealing with small amounts of weed or large amounts of powder.

  • Proud globohomo
  • And that's just science; think of all the actual conspiracies that actually happened. MKULTRA is perfect conspiracy theorist material and actually real, but that second part means it's boring

  • US to probe Tesla's 'Full Self-Driving' system after pedestrian killed in low visibility conditions
  • Regarding point number 2, I have no doubt we'll be able to develop systems that process visual/video data as well as or better than people. I just know we aren't there yet, and Tesla certainly isn't.

    I like to come at the argument from the other direction though; humans drive with eyesight because that's all we have. If I could be equipped with sonar or radar or lidar, of fucking course I'd use it, wouldn't you?

  • Question for paramedics

    If I'm injured and need a blood transfusion, where are paramedics most likely to go for the needle; is it the vein in my arm, same as for blood donation?

    Wherever it is, if I get a tattoo noting my blood type, are you going to trust the tattoo and give me my blood type, or would you disregard it and go with O- just in case?

    I'm getting some tattoo work done anyways, and I really like the idea of a Canadian Blood Services logo plus my blood type wherever paramedics would see it, but it's pointless if they won't believe it

    Oh look, it's LCL

    Long press on links to open them externally

    When reading a web page within Connect, it would be nice if long-pressing on links in the webpage would give a popup with the option to open the link in an external browser (and probably also an option to just copy the link). I frequently find myself linked to Wikipedia from a Lemmy comment, and then want to open other links from that wiki page, so then I have to open the page I'm on externally and refind my spot in the article.

    Having the same options when long-pressing a link in a comment/post would be nice as well.

    Seperate block lists for seperate accounts

    Edit: there's already a setting for it, another user pointed it out. Ignore me :)

    Currently, when you block an instance or community, it's blocked app-wide. I had blocked various NSFW communities and instances on my main account so that they don't show up in my All feed, but now I can't access them from my NSFW account unless I use a different app to do so, or repeatedly unblock and reblock them as needed.

    Can we instead make block lists on a per-account basis (or have the option of account-associated or global blocking)?

    How can I change the text colour in my comment box?

    The text when I try to type comments (but not the text in the search bar or, as I'm just now learning, here in the 'post body' text box) is white, and I can't find the setting to change it. Obviously I could change my background back to the default blue that it was, but that's the opposite of a solution.

    Anybody know?
