  • There is no possible way to actually stop teenagers accessing online porn that doesn’t require such a massive invasion of privacy that it leaves no safe way for adults to access it. To go with your adult video store analogy, it’s like if the store staff would have to accompany you home and watch you watching the porn to check there wasn’t anyone standing behind you also looking at the screen, and while they were there, they were supposed to take notes on everything they saw. Even if they had no interest in doing anything nefarious, a criminal could steal their notebook and blackmail all their customers with the details it contained, and there’d be enough proof that there wouldn’t be any way to plausibly claim the blackmailer had just made everything up.

    If you want to prove someone on the Internet is a real adult and not a determined teenager, you need lots of layers. E.g. if you just ask for a photo of an ID card, that can be defeated by a photo of someone else’s ID card, and a video of a face can be defeated by a video game character (potentially even one made to resemble the person whose ID has been copied). You need to prove there’s an ID card that belongs to a real person and that it’s that person who is using it, and that’s both easier to fake than going to a store with a fake ID (if you look young, they’ll be suspicious of your ID) or Mission Impossible mask, and unlike in a store, the customer can’t see that you’re not making a copy of the ID card for later blackmail or targeted advertisements. No one would go back to a porn shop that asked for a home address and a bank statement to prove it.

    Another big factor is that if there’s a physical shop supplying porn to children, the police will notice and stop it, but online, it’s really easy to make a website and fly under the radar. It’s pretty easy for sites that don’t care about the law to provide an indefinite supply of porn to children, and once that’s happening, there’s no reason to think that it’s only going to be legal porn just being supplied to the wrong people.

    Overall, the risk of showing porn to children doesn’t go down very much, but the risk of showing blackmailable data to criminals and showing particularly extreme and illegal porn to children goes up by a lot. Protecting children from extreme material, e.g. videos of real necrophilia and rape, which are widely accepted to be seriously harmful, should be a higher priority than protecting a larger number from less extreme material that the evidence says is less harmful, if at all. Even if it’s taken as fact that any exposure to porn is always harmful to minors, the policies that are possible to implement in the real world can’t prevent it, just add either extra hassle or opportunities for even worse things to happen. There hasn’t been any proposal by any government with a chance of doing more good than harm.




  • You’re completely neglecting likely doses. If, instead of using it to clean a resin print, you drank the amount of isopropyl alcohol that you’d have used, then wait a day for your liver to clean things up, you’d be in about the same condition as if you’d drunk a whole bottle of wine and waited a day. Obviously, that’s not something that’s healthy to do regularly, but it’s not going to kill you if you do it once, and it’s something that some people choose to do several times a week then go on to live well beyond the average life expectancy.

    However, you don’t drink the isopropyl alcohol. You just inhale some of it. Unless you’re going out of your way to huff it, you won’t inhale a whole millilitre, and then most of what you inhale will be exhaled without being absorbed. If you do that once a week for a year, your liver will be in comparable condition to if at some point in that year, you had a beer once. As we all know, anyone who ever drinks a single beer immediately dies, so your life is over.

    While isopropyl alcohol is metabolised slightly differently to ethanol, going via acetone, the amount that gets into your body from incidental exposure as would happen with resin printing (especially if taking the kind of precautions necessary for the resin itself) would be metabolised into less acetone than is always in a healthy human body due to it being a byproduct of lots of things human cells normally do.

    Again, hand sanitiser and pre-injection swabs, both of which doctors rub on skin, have isopropyl alcohol as their main ingredient, enough for it to give hospitals their distinctive smell, so being able to smell isopropyl alcohol is not a sign that you’re getting a dose that you should worry about.


  • Isopropyl alcohol is significantly less toxic than the vapours from the resin itself, even if it’s water-washable. It’s somewhat more poisonous than regular alcohol, so it’s not a good idea to actively drink it, but it’s safe to inhale in reasonable quantities and get on your skin (as long as you’ve not mixed it with printer resin), hence being the main ingredient in hand sanitiser and pre-injection swaps.

    As for the cost, it’s inexpensive enough to balance with the cost saving from non-water-washable resin of comparable quality generally being a little cheaper. It’s not like you use a whole five-litre jug per print.








  • I’ve got an SV08. It’s not a perfect printer, but making a printer without the problems it has (e.g. the bed takes nearly an hour to settle after it’s reached temperature, so it needs a long preheat for all but the shortest prints) would require making it much more expensive (e.g. a thick aluminium or graphite bed that wouldn’t warp would add another 20% of the cost of the printer). That specific problem is sidestepped with the MK4S by simply having a much smaller build volume rather than because it’s higher-end and more expensive. I’ve not needed support from Sovol (yet?), so can’t comment on whether they’re still super slow like they supposedly were right after the SV08 launched.

    I’ve got a textured PEI bed and when I’ve printed TPU, the adhesion has been perfect, i.e. good enough that the part wasn’t going to go anywhere unless I wanted it to, but still easy enough to remove when the print was done and the bed had cooled. I guess it could vary from filament brand to brand, so it’s possibly worth trying the same brand as I used, which was cheap Geeetech stuff. It’s £8 a roll, and I’ve used their cheap PLA for ages. I wouldn’t recommend their ABS+, though, as it seems to break down at the lowest temperature that gives reasonable layer adhesion.

    AGPL is a full-on FOSS licence with strong copyleft requirements, not a measly open-source licence like Apache, which could be pivoted to proprietary at a moment’s notice. We’re communicating through an AGPL-licensed system right now as it’s what Lemmy’s licensed as. If they were going for a corporate-friendly licence, AGPL is the last thing they’d choose as it forces you to share source code with even more people than the regular GPL does.
