  • As someone who’s just spent half an hour reading Wikipedia thanks to this thread, I can now dispense a summary of what I read to make it feel like I didn’t just waste a chunk of time I should have spent in bed by wasting another chunk of time I should be spending in bed.

    Fats are made out of fatty acids, which are carboxylic acids with a longish carbon chain. A saturated fatty acid only has single bonds between carbon atoms, a monounsaturated fatty acid has a single double bond somewhere in the chain (and these are sometimes things that turn into buzzwords, e.g. omega three oils are ones where there’s a single double bond three along from the end of the chain), and a polyunsaturated fatty acid has more than one double bond.

    Single bonds in a carbon chain can only be one way around, so you don’t get isomers of saturated fatty acids, but double bonds in a carbon chain can be in either of two orientations. If the hydrogens are on the same side for both sides of the bond, that’s the cis orientation, and if they’re on opposite sides, that’s the trans orientation. Most natural unsaturated fats are cis, so they generally don’t get explicitly labelled as cis fats, and just the trans ones get the extra label. Notably, though, vaccenic acid, which is about 4% of the fat in butter, is trans by default, so it’s cis-vaccenic acid that gets the extra label.

    Unsaturated fats tend to be more liquid at room temperature, but can be made by growing cheap vegetables. They also go off faster as free radicals can attack the double bonds. Saturated fats tend to be solid at room temperature, but mostly need to come from animals or more expensive plants (palm fat is an exception - it’s cheap and mostly saturated). It’s therefore desirable to use industrial processes to artificially saturate fats, and we can do that by heating them up and exposing them to hydrogen in the presence of a catalyst like Nickel. You don’t necessarily want to fully saturate your fat, though, so might stop part way, and if you do, unless you intentionally tweak the process to avoid it because it’s the 21st century and you’re legally obliged to, you get some of the partially hydrogenated fat switching from cis to trans.

    Over the course of the last century, we realised that (except for a few like vaccenic acid) trans fats are harmful in lots of exciting ways, e.g. messing up cholesterol, blocking your arteries, and building up in your brain. They’ve therefore been banned or restricted to certain percentages in a lot of the world. You can get a similar effect by fully hydrogenating things to get safe (or at least safer) saturated fat and mixing it with the unmodified fat, or by switching everything that used to use hydrogenated vegetable oil to using palm oil, which is one of the driving forces behind turning rainforests into palm plantations.

    Apparently, this was twenty five minutes of writing, so I’m nearly up to an hour of thinking about fats.


  • When they first started ramping up ads and demonetising more videos for being insufficiently advertiser-friendly, they probably still had enough goodwill from users that if they’d immediately launched YouTube Premium and presented it as a way to both remove ads, and support video creators that couldn’t rely on ad revenue, it would have been decently successful. A good number of YouTubers who had to switch to sponsorships and Patreon could have been pushing for people to subscribe to Premium instead of play Raid: Shadow Legends, which presumably would have boosted subscriber counts, and might have been enough to make YouTube profitable and much more pleasant for both free and premium users than it is today. Instead, they burned through a large amount of goodwill before implementing Premium, so people were already more reluctant, and for a long while it only shared revenue with a select few channels who were already raking in ad money, and was unaffected by view counts, so early Premium subscribers were paying Logan Paul even if they never watched that kind of video, but weren’t paying the channels they actually watched.


  • I said he more-or-less killed him, not that he actually killed him. Care was not taken to ensure he’d be revived or revivable. He was left forgotten in a pocket. The likely outcome was that he remained forgotten and didn’t get wet until he’d been dropped under some furniture, crushed like a stock cube or gone mouldy. Maybe he had dependents, like a young child who’d have died without their parent. It being theoretically possible to revive someone later doesn’t make turning them into a dehydrated cube meaningfully better than making them dead if you don’t have a strong plan with a failsafe to make sure they stop being a cube. Even with guaranteed revival, if they’re a cube for long enough that they notice the lost time, it’s just like roofying someone and holding them hostage for a while. Do not turn museum guys into dehydrated cubes.





  • It’s not realistic to demand to own games in the same way as a spoon any time soon. It is, however, pretty reasonable to demand you own games like you’d own a book. You can chop up a book and use it to make a paper maché dog, but you can’t chop up the words within to make a new derivative book (or just copy them as its to get another copy of the same book except for a single backup that you’re not allowed to transfer to someone else unless you also give them the original). The important things you can do with a book but not a game under the current system, even with Gog, are things like selling it on or giving it away when you’re done with it and lending it out like a library.

    About a hundred years ago, book publishers tried using licence agreements in books to restrict them in similar ways to how games and other software are restricted today, but courts decided that was completely unreasonable, and put a stop to it. In the US, that’s called the First Sale Doctrine, but it has other names elsewhere or didn’t even need naming. All the arguments that applied to books apply equally well to software, so consumers should demand the same rights.





  • To go one better, there’s http://isthereanydeal.com/, which tracks prices across a bunch of vetted key retailers (i.e. companies that buy wholesale keys from publishers and sell them to users, but not grey-market or dodgy sites) so you can see where’s cheapest and get notified of discounts etc.

    Why check GreenManGaming and Steam (and potentially a bunch of their competitors, too) when you could check one site and know who’s best?

    I’ve accidentally made this read like an ad, but they’ve not paid me to say this, I just always check the site before buying games, and have either saved loads of money by doing so over the years, or have ended up buying a bunch of things I’d have ignored on the grounds they were too expensive otherwise. I don’t know in which direction, but it’s definitely changed the amount I’ve spent on games over the last ten years.


  • I’m pretty sure Reddit used to be profitable. There used to be a bar on the right-hand side that showed how far each day’s Reddit Gold purchases had gone towards covering the day’s server costs. When I first started using Reddit, it’d typically be about a third of the way full when it reset, but a few years after the at, it was filling up after about eight hours, suggesting they were covering the server costs three times over, which should have left plenty of money for staffing costs as they didn’t have many staff back then. Eventually, they got rid of the bar. Later, they did things that would have increased costs, like hiring people to make New Reddit and the Reddit App, and hosting images and videos themselves instead of leaving it to imgur, and I guess these were enough to make them no longer profitable and force them to aim for faster growth.


  • I was reinforcing your point about using a monitor and a Linux PC not being able to replace all the things a smart TV can do. You said streaming would work, but regular TV channels wouldn’t, and I pointed out that even streaming would be limited as the major streaming services don’t allow full quality via a browser, especially on Linux where HDCP can’t work.


  • I’m not arguing for anything in the post above, just pointing out that a broken (or badly repaired) insulin pump is genuinely more dangerous than having no insulin pump. That doesn’t have to count against the right to repair one, as if you’ve got the right to repair an insulin pump, and do so badly, it doesn’t mean you’re legally forced to use it afterwards, just like I’ve got the right to inject all the insulin in my fridge with an insulin pen back to back, but I’m not legally forced to do so.

    I do think the right to repair should be universal, but as I think that medical stuff should be paid for by the state, NHS-style, that would end up meaning that the NHS could repair medical devices themselves if they deemed it more economical to do so and recertify things as safe than to get the manufacturer to repair or replace them. The NHS is buying the devices, and gets the right to repair them, and that saves the taxpayer money, as even if they don’t actually end up repairing anything, it stops manufacturers price gouging for repairs and replacements, and if the manufacturer goes bust or refuses to repair something, there’re still ways to keep things working. It doesn’t mean unqualified end users can’t use their new right to repair their medical devices and risk getting it wrong, but if you’ve got an option of a free repair/replacement, most people would choose the safe and certified repair over their own bodge.



  • If you’ve got a broken insulin pump, assuming you’re in a country with a functioning healthcare system, you should have been given a spare pump with the original, and probably some insulin pens, so when one breaks, you fall back to the spare, and get given a new one to be the new spare (or could get the broken one repaired). Using the spare is completely safe.

    If you don’t have a spare, your sugars would go up over several hours, but you’d have a day or two to get to a hospital and potentially several days after that for someone to find you and get you to a hospital, so it’s not safe, but also not something you’d die from if you had any awareness that there was a problem.

    If you’ve got an incorrectly-repaired pump, you could have it fail to give you enough insulin, and end up with higher sugars, notice the higher sugars, and then switch to the spare. That’d be inconvenient, but not a big deal. However, you could also have it dump its entire cartridge into you at once, and have your sugars plummet faster than you can eat. If you don’t have someone nearby, you could be dead in a couple of hours, or much less if you were, for example, driving. That’s much more dangerous than having no insulin at all.

    Prosthetic legs don’t have a failure mode that kills you, so a bad repair can’t make them worse than not having them at all, but insulin pumps do, so a bad repair could.



  • In real life, all quantum entanglement means is that you can entangle two particles, move them away from each other, and still know that when you measure one, the other will have the opposite value. It’s akin to putting a red ball in one box and a blue ball in another, then muddling them up and posting them to two addresses. When opening one box, you instantly know that because you saw a red ball, the other recipient has a blue one or vice versa, but that’s it. The extra quantum bit is just that the particles still do quantum things as if they’re a maybe-red-maybe-blue superposition until they’re measured. That’s like having a sniffer dog at the post office that flags half of all things with red paint and a quarter of all things with blue paint as needing to be diverted to the police magically redirect three eighths of each colour instead of different amounts of the two colours. The balls didn’t decide which was red and which was blue until the boxes were opened, but the choice always matches.
