The good advice that they just won’t take is spot on for the Arch Wiki, though.

Windows permissions are more flexible than basic Unix ones. A file doesn’t just have an owner and a group, it can have individual permissions for arbitrarily many entities, so taking ownership doesn’t remove any of the permissions from anything that already had access, it just adds more. The command shown here is closest in effect to deciding you’re always going to log in as root from now on, although Windows has a way to effectively do that without modifying the ACL of every file. Either way, it’s silly, and usually people who suggest it are under the impression that XP did permissions right by not meaningfully enforcing them and not having an equivalent of a root account you can temporarily switch to, and Vista only changed things specifically to annoy people, and not to be more like Unix.

Those photos are of Shah-era Iran, when the West was propping up (including providing weapons, training and funding to) an unpopular authoritarian that had been installed by the UK and US when the previous democratically-elected government dared to attempt to nationalise the oil industry, which was owned by BP. Under the Shah, traditional Islamic dress was outlawed, which is why everyone’s in 1970s clothes. If you disagreed with the Shah, the secret police would take you away and kill you.

Eventually, a coalition of leftists and religious leaders overthrew the Shah. The religious faction then assassinated all the prominent leftists and switched the secular authoritarian dictatorship for a theocratic authoritarian dictatorship. Under the Ayatollah, traditional Islamic dress was mandatory, which is why women in contemporary photos from Iran always have some kind of headscarf unless it’s in a news report about a protest that someone got executed for. If you disagree with the Ayatollah, the Revolutionary Guard will take you away and kill you.

So Iran’s had laws forcing women to wear only the clothes approved by a dictator both with and without help from the West.

They’re AAAA cells, not AAA cells, which is why you’re finding they’re too short and narrow.

You can weigh it before you start drying it and weigh it again every few hours until it stops getting lighter.

That will be in large part because of the changes to the non-dom tax rules, where (broadly speaking) you could live in the UK, but opt out of the UK’s tax system and pay tax somewhere else where there wasn’t any tax. The people who left will largely be people who weren’t paying a meaningful amount of tax anyway.

It’s not clear that the AGPL is enforceable in lots of countries, so the GPL is safer if you don’t need the extra restrictions.

The open source movement was corporations trying to have their cake and eat it too with the things the free software movement had done. That means organisations calling attention to open source without mentioning free software will always push against copyleft as their goal is to get free labour and testing for things megacorporations use while reserving the right to take future development private.

You can’t. Blocking commercial use stops a licence being open source. If you don’t want commercial competition, then you need copyleft, so anyone using your code has to share their modifications with whoever they give binaries to. If they end up using your code to make a better product, then it’ll have to be open source, too, and you can incorporate the improvements back into your version.

The paper the article is referencing says they made their own PVA glue from pellets so they could get the thickness they wanted, and they did so by dissolving them at 80°C, so it sounds like the glue is soluble, just only in hot water, and all the clothes I ruined as a child could have been saved by using a different setting on the washing machine.

It’s not quite the same stuff as glue. PVA glue is polyvinyl acetate, and PVA filament is polyvinyl alcohol. The glue doesn’t dissolve in cold water like the filament does.

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.

That’s not unique to water-based resin, though. You can leave the dirty alcohol out in the sun, and if you’re waiting for it to evaporate, that takes less time with alcohol than with water.

Water-based resin isn’t any less toxic or safer to dispose of, it’s just more soluble. You can’t put water that’s washed uncured resin down the sink until you’ve exposed it to UV for long enough for the resin to cure and precipitate out, and you still need to ventilate the fumes.

The UK has a lot of ethnic Indians because of the empire and encouraging immigration to replace people who didn’t survive WWII. The Labour Party has about as many people with Indian heritage as would be expected given population demographics. It’s probably just more than in Canada, so it seems like a lot to you.

If you’ve got a magnifying glass, your phone will be able to autofocus much closer if you put the magnifying glass between the camera and the object.

Sometimes the ones that are a fifth the price on AliExpress are the ones that failed QA testing for the whitelabeller, or they’re the same board with lower-rated components attached, so they’re not necessarily identical.

A trick is to weigh the filament before you start drying it and then weigh it again every few hours to see if it’s stopped getting lighter. If it’s been hours since it lost a single gram, then it’s probably close enough to as dry as it’s going to get, and if it still doesn’t behave, then there must be a second problem.

Someone doesn’t understand the Windows design language. Anxiety would be a yellow warning triangle. That’s a red error circle, so something really has gone wrong and you’re right to be panicking about it, and better remember what it is before the consequences become too dire.
