They don’t take all of it, so if they’re doing what they’re supposed to, nearly all the crabs will be returned to the ocean within a few days and eventually be fine again. Some do die, though, and even if they don’t, they’re worse for wear after the process, and some companies have been accused of taking all the blood and then selling the dead crabs as fishing bait. There’s an artificial alternative available, but regulators aren’t all convinced it’s as effective, so it isn’t used universally yet.
- Comment on You probably can't trust your password manager if it's compromised 2 weeks ago:
Password managers are supposed to be designed to resist a situation where they’re compromised, and are only ever supposed to see a mysterious blob of encrypted data without ever having access to any information that would help decrypt it. The headline’s more like M1 Abrams Tanks Vulnerable to Small Arms Fire - it’d be totally expected that most things die when shot with bullets, but the point of a tank is that it doesn’t, so it’s a big deal if it does.
- Comment on Question: Humidity controlled cabinet 2 weeks ago:
The DHT11 has been replaced twice with similarly-priced but more accurate models, first the DHT22 and then the AHT20. In my experience, the AHT20 is a lot better than the DHT22, mainly because its power consumption is far lower, so it doesn’t mess up its readings by getting hot.
Also, at that size, I’d be very surprised if the dehumidifier has a compressor. It’s much more likely that it’s got a Peltier plate, and they’re not very good. They use a lot of power to develop and maintain a fairly small temperature difference, so if they’re in a confined space, they heat up the air quite a bit, and then the water from their tank will more easily evaporate.
If you’re willing to spend some money, a solid state ion membrane dehumidifier might be better for a small cabinet than a compressor-based one, as it’ll be easy to ensure the water goes out of the cabinet instead of into a container that can’t be emptied without opening the cabinet and letting more humidity in. They’re definitely not cheap, though. I think they’re still under patent as there’s only one manufacturer that I can find, so maybe they’re the dehumidifier of the future even if they’re not suitable right now.
- Comment on Give your Matrix account a Discord UI with Commet 3 weeks ago:
If it’s the problem that I’ve seen people complain about in the past, it’s effectively the same as HTTPS ‘not supporting’ end to end encryption because it runs over IP and IP packets contain the IP address of where they need to go, so someone can see that two IP addresses are communicating, which is unavoidable as otherwise there’s nothing to say where the data needs to go, so no way for it to get there. Someone did a blog post a couple of years ago claiming Matrix was unsecure as encrypted messages had their destination homeserver in plaintext, but that doesn’t carry any information that isn’t implied by the fact that the message is being sent to that homeserver’s IP.
- Comment on What to do with a roll of unprintable filament 3 weeks ago:
It was £7, so likely not worth the effort - if they want me to pay to ship it back, then that would cost about as much as the roll did - and it’s now outside the warranty period, so that would be pointless anyway.
- Comment on What to do with a roll of unprintable filament 3 weeks ago:
When it’s hot, it stinks of hot ABS, and it dissolves in acetone. I’ve read that sometimes budget filament manufacturers will use the same pigment across their whole material range, even if it’s not capable of withstanding the print temperatures of some of them, but it’s ABS+ rather than pure ABS, so it could be full of mystery additives that don’t handle heat well, too.
There’s not much point using it as glue as I’m not going to get through a whole kilo worth of ABS glue, and produce more than enough ABS scraps from test prints and support to always make a colour-matched glue anyway.

It’s a federated Twitter alternative. It’s existed for a while - the initial release was in 2016, but obviously with all the Musk-related nonsense in the past few years, it’s grown a lot.
- Comment on YSK You can buy a @linux.com domain for email flex 3 weeks ago:
There are situations they don’t cover, e.g. if you choose a sender address from the same domain as the real address. Obviously, lots of email services check for that, but it’s not universal - it was a great tool for pranks at university for me.
- Comment on YSK You can buy a @linux.com domain for email flex 3 weeks ago:
The from field in an email is something that the sender sets, and they don’t have to set it to anything in particular. Unless your email client stops you (which is pretty common these days) you can just enter a made up address, another address that you’d rather receive replies through, or someone else’s address. It’s one of the reasons why phishing emails work - there’s nothing stopping a scammer impersonating anyone they want to.
- Comment on Man posts his incorrect opinion online 4 weeks ago:
I reckon it depends on how warm someone’s home is and how good their circulation is. If I don’t have shoes on indoors, then for half the year it feels like my feet have been stabbed because they get so cold (slippers are not enough), but I don’t wear the same shoes indoors as outdoors. I suspect that if we set the heating higher and the house wasn’t constructed in a way that makes the floor always much colder than a few inches above the floor, this wouldn’t be a problem.
- Comment on Game companies see share prices plummet following the launch of Google's very limited virtual world generator, Project Genie 4 weeks ago:
Investors managed to pour billions into making the metaverse bubble, even though that was just video games being invented a second time by people so uninterested in them that they hadn’t noticed they’d already been around for decades. There’s no reason to think that investors know what they are beyond something on a computer, so obviously they’d see something else on the computer as a viable competitor.

With energy prices in the UK being what they are, it’s only raw potatoes that are cheaper than bread. At least toast toasts quickly, so isn’t that energy-intensive compared with boiling a pan of water.
- Comment on Designed a simple photo frame on FreeCad. Why are some layers peeling in my print? 5 weeks ago:
Fillets are easier to print horizontally than chamfers as they spread the acceleration (i.e. the thing that makes sharp corners bad) over the while fillet instead of just splitting it into two stages like a chamfer would.
Chamfers are easier to print vertically than fillets as the overhang is limited and consistent.
There’s no overhang for a horizontal corner as you’re printing the same shape onto the layer below, and no acceleration for a vertical corner as it’s entirely separate layers so the toolhead never has to follow the path of the corner.
It sounds like you’ve read (or only remembered) half a rule. It’s not the case that either half of the rule is used the majority of the time because 3D printers are used to print 3D objects, so they always produce objects with both horizontal and vertical edges.
- Comment on That's a whole lotta hydrogen! 5 weeks ago:
But this guy says it, and he’s defined himself to be the sole authority, so that matters more than any number of biologists.
Every argument they come up with has been refuted in past threads, and they just dismiss anything they disagree with as irrelevant, but treating tenuous sources like a supposed screenshot of Imane Khalif’s SRY test originating from an obscure site that’s never been republished by a mainstream one, even if they’d been calling for her to be barred from future tournaments based on no evidence so would love to vindicate their stance with test results.
It’s not worth your time to engage with them in good faith.

- Comment on Helldivers 2 gets new stealth missions today, and its super-slimmed install size version is finally ready to take over 1 month ago:
It’s not exactly a rootkit - if you just don’t agree to the UAC prompt while it’s installing, it’ll refuse to install rather than doing the thing that makes it definitionally a rootkit and managing to gain admin access without the user’s permission - but the game does still require kernel-level anti-cheat.
- Comment on Cyberpunk 2077 VR mod flatlines, after CD Projekt file DMCA strike and request its creator drop their paywall 1 month ago:
Generally when you see people advocate for not having to pay for things like that, it’s because they want to do away with currency and the concept that a living is something that needs to be earned rather than something everyone gets as a basic right. Plenty of people make art, including games, without a profit motive, so it’s not unreasonable to think that enough games would be made if everyone had way more free time and games were all made for free.
- Comment on Fear that quantum computing is on the cusp of cracking cryptocurrency's encryption spurs a global investment firm to remove Bitcoin from recommendations 1 month ago:
In theory, quantum computing should be faster once hardware that’s faster is available, and only if the problem you’re trying to solve is in BQP, which isn’t that much of what computers are used for. Progress has been slow, but continuous, so the gap between simulating a quantum computer and actually using one has been shrinking. In October last year, Google’s Willow chip was verified to have achieved quantum advantage, i.e. done something that could be checked externally faster than a classical computer could have. It was only 13,000x faster, and in one specific task, which isn’t really enough to change the world, but ten or twenty years ago it was still thought to be fairly plausible that the physics might not be right and even if the practical problems were solved, they still wouldn’t work.
Even if quantum computers get ludicrously fast, they’re still not going to be especially common, and they’ll be a piece of specialised equipment, more like an electron microscope than a home PC. Most people just don’t need to do any stuff that’s in BQP, so don’t care if they can do it faster. If you’re a company, university or government body that needs to do one of the very specific things that will be faster, though, they’ll be indispensable.
- Comment on Priming and sealing a painted print 1 month ago:
I’ve never actually needed primer to paint PLA unless the paint I was using was terrible, and wouldn’t have stuck to the primer very well, either. Tamiya’s acrylics have been entirely issue-free for me, both with a brush, or thinned and airbrushed, and they’re not that expensive, but I’ve also had acceptable results with random fifteen-year-old tubes of really cheap acrylics that were sold more as a children’s toy than a serious paint (although a lot of these tubes had gone bad in that time) and with Humbrol and Revel acrylics and enamels (although their acrylics come in pots that don’t seal very well, so it’s not that uncommon for them to be already cured when you first open them - if you’re buying liquid acrylics for model painting, Tamiya is a better choice).
- Comment on Should speakers hum when they're connected to a stereo, but the volume of is turned all the way down? 1 month ago:
If the ferrite is filtering a hum you can hear, it’s also filtering parts of your music that you can hear because a ferrite just dampens a frequency range and can’t tell what is and isn’t supposed to be there.

- Comment on Will the government be able to put 2 & 2 together 1 month ago:
Obviously they’ll have a carve-out for businesses that apply for a VPN licence and have the other end of the VPN remain in the country. Not because they listen to the public saying that VPNs have legitimate uses, but because the megacorp they consult with before drafting the law says it’s the only legitimate use-case and has a VPN product they can sell to small businesses that can’t afford to wait for their self-hosted VPN to be certified by the one overworked civil servant who has sole responsibility for approving every VPN licence.

OED:
- totally or partially resistant to a particular infectious disease or pathogen.
- protected or exempt, especially from an obligation or the effects of something.
Merriam Webster
- : not susceptible or responsive especially: having a high degree of resistance to a disease
- a: produced by, involved in, or concerned with immunity or an immune response
If you have a sample of HIV at 37°C in blood, but with all the immune cells removed, it’ll still all become inert after around a week simply due to chemical reactions with other components of blood etc… It’s pretty comparable to a population of animals - if you take away their ability to reproduce, they’ll die of old age when left for long enough even if you’re not actively killing them.
- Comment on Get on that grindset 1 month ago:
- this is a shitpost community, not a biotech publication, so immune here means the dictionary definition, not any domain-specific technical jargon, otherwise people can’t make shitposts about diplomatic immunity
- lacking the receptor that HIV uses to hijack the regular immune response in order to reproduce means the regular immune response destroys it
- even in a normal person, after exposure, a lot of HIV gets destroyed by other parts of the immune system, often enough to eliminate it before an infection gains a foothold. Once an infection takes hold, it outbreeds the immune response as it’s the part best equipped to deal with a large viral load that it interferes with.
- if you’ve got the virus in your body, but due to the lack of the receptor, it can’t reproduce, then it doesn’t remain viable for very long as each viron accumulates damage over time, and ceases to function once it’s too badly damaged. People carrying a disease have enough viral reproduction going on to balance out the virus being destroyed.
- Comment on Get on that grindset 1 month ago:
Even if you ignore that there’s an entirely valid sense of the word immune that has nothing do do with biology (i.e. the one in phrases like diplomatic immunity), my original comment is entirely consistent with the dictionary definition of the biological sense of the word. There are probably sub-fields of biology where immunity is used as jargon for something much more specific than the dictionary definition, but this is lemmyshitpost, not a peer-reviewed domain-specific publication.
- Comment on Get on that grindset 1 month ago:
When a normal person is exposed to HIV, it reproduces inside of them, so can then go on to expose more people, and if there’s enough of it, infect them in turn (if there’s a smaller amount, their immune system will normally be able to clean it up before it gets enough of a foothold). If someone’s lacking the receptor, then no matter how much they were exposed to, their immune system will eventually manage to remove it all without becoming infected because it can’t reproduce. If they had a ludicrously large viral load, then there’s a possibility that it could be passed on before it was destroyed, but most of the ways people get exposed to HIV aren’t enough to infect someone who’s vulnerable, let alone infect someone else via secondary exposure if there’s not been time for the infection to grow.

The vast majority of NATO that isn’t the US is covered by the EU’s Mutual Defence Clause, so this kind of already exists. It sucks for the NATO members that aren’t in the EU, though, e.g. Greenland.
- Comment on Get on that grindset 1 month ago:
People without the receptor that HIV targets are immune to HIV because of that, like how a rock is immune to verbal abuse or double foot amputees are immune to ingrown toenails. The immune system being able to kill something isn’t the only way things can be immune to other things.
- Comment on I tested putting my printsheet in the dishwasher 1 month ago:
Enzymes are specific to a particular molecule, or class of molecules with a particular pattern. A PEI buildplate is not getting eaten by the proteases in a dishwasher tablet. The reasons you’re not supposed to rinse things before putting them in the dishwasher are:
- most dishwashers have sensors to detect how much material is ending up in the water, and if things have been rinsed, it can mislead them into thinking the load is lighter than it really is.
- dishwashers replace some of the dirty water part way through the load, and the enzymes are more soluble than the dirt, so if there’s not much food residue for them to stick to, they can end up getting rinsed away part way through the cycle.
- it uses water and your time to rinse the dishes first, which is a waste if it doesn’t make them end up any cleaner.
