Blue-ringed octopuses, comprising the genus Hapalochlaena, are four extremely venomous species of octopus that are found in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia. They can be identified by their yellowish skin and characteristic blue and black rings that can change color dramatically when the animals are threatened. They eat small crustaceans, including crabs, hermit crabs, shrimp, and other small sea animals.

They are some of the world's most venomous marine animals. Despite their small size—12 to 20 cm (5 to 8 in)—and relatively docile nature, they are very dangerous if provoked when handled because their venom contains a powerful neurotoxin called tetrodotoxin.

The species tends to have a lifespan around two to three years, which may vary depending on factors such as nutrition, temperature, and the intensity of light within its environment.

Behavior

Blue-ringed octopuses spend most of their time hiding in crevices while displaying effective camouflage patterns with their dermal chromatophore cells. Like all octopuses, they can change shape easily, which allows them to squeeze into small crevices. This, along with piling up rocks outside the entrance to their lairs, helps safeguard them from predators.

If they are provoked, they quickly change color, becoming bright yellow with each of the 50–60 rings flashing bright iridescent blue within a third of a second, as an aposematic warning display. In the greater blue-ringed octopus (H. lunulata), the rings contain multilayer light reflectors called iridophores. These are arranged to reflect blue–green light in a wide viewing direction. Beneath and around each ring are dark-pigmented chromatophores that can be expanded within one second to enhance the contrast of the rings. No chromatophores are above the ring, which is unusual for cephalopods, as they typically use chromatophores to cover or spectrally modify iridescence. The fast flashes of the blue rings are achieved using muscles that are under neural control. Under normal circumstances, each ring is hidden by contraction of muscles above the iridophores. When these relax and muscles outside the ring contract, the iridescence is exposed, thereby revealing the blue color.

Toxicity

The blue-ringed octopus, despite its small size, carries enough venom to kill 26 adult humans within minutes. Their bites are tiny and often painless, with many victims not realizing they have been envenomated until respiratory depression and paralysis begins. No blue-ringed octopus antivenom is available

The octopus produces venom containing tetrodotoxin, histamine, tryptamine, octopamine, taurine, acetylcholine, and dopamine. The venom can result in nausea, respiratory arrest, heart failure, severe and sometimes total paralysis, and blindness, and can lead to death within minutes if not treated. Death is usually caused by suffocation due to paralysis of the diaphragm.

Direct contact is necessary to be envenomated. Faced with danger, the octopus's first instinct is to flee. If the threat persists, the octopus goes into a defensive stance, and displays its blue rings. If the octopus is cornered and touched, it may bite and envenomate its attacker.

Conservation

Currently, the blue-ringed octopus population information is listed as least concern according to the International Union for Conservation of Nature. Threats such as bioprospecting, habitat fragmentation, degradation, overfishing, and human disturbance, as well as species collections for aquarium trade, though, may be threats to population numbers. Hapalochlaena possibly contributes to a variety of advantages to marine conservation. This genus of octopus provides stability of habitat biodiversity, as well as expanding the balance of marine food webs.

Favorite part of Thanksgiving spending hours trying to not visibly want to leave, hit my limit, ask my partner if she wants to start to go, then having to wait like an hour for her to fucking START to go

I'm so fucking ready to go and it's just standing around for ????? Time waiting while people just keep talking about random shit god kill me

edit: p.s. i know this makes me seem insufferable and I am I just don't know what to do with myself in 6+ person groups where everyone is talking about some random thing, even if it were smaller groups like I have an hour ish of conversation in me before I am like ok i want to do something else now pls

Are there any video games from the last five or ten years which have actually taken advantage of how powerful PCs and consoles have become? I don't mean hyper-realistic graphics and massive uncompressed textures, but games that genuinely would not have been possibly before the current gen of gaming. Because it seems to me like we've been getting diminishing marginal returns for a while

[–] Le_Wokisme@hexbear.net 1 points 6 minutes ago

on the CPU side Crysis was made assuming clock speeds would keeo getting higher but instead of having 6 gigahertz single-core CPUs we have slower 16 core ones and shit, and games have not been very good about utilizing multiple processor cores.

PUBG is 8 years old now but that was/probably is CPU-bottlenecked for a lot of people and something like that is probably pushing it on what they're doing on the CPU side.

i can't remember the name of it but there's a youtube series from some guy making no-gpu graphics stuff because CPUs are orders of magnitude more powerful than they were 30 years ago when people didn't have GPUs

[–] FunkyStuff@hexbear.net 4 points 1 hour ago* (last edited 1 hour ago)

There's some sim games that fully utilize the CPU:

Noita's particle simulation is pretty incredible and the fact that it works online with the Noita Together mod is also wild. Regular gameplay is not the limit, but if you're going for some of the challenges you'll have runs that begin to test the limits of the physics engine and your hardware with extremely powerful wands and manipulating large amounts of terrain. This does all happen in the CPU.

Teardown is a similar thing but in 3D. IIRC the simulation is a bit simpler for Teardown and it runs in the GPU though I might be wrong.

Certain automation scenarios in modded and vanilla Minecraft stretch the limits of CPU hardware. These probably won't come up for 90% of players, though.

I can't think of any games that are doing completely innovative stuff with compute shaders (i.e. doing massively parallel computation on the GPU) in a transformative, totally unprecedented way. I think there's a bit of a materialist explanation here, though. AAA is very live service oriented because it's just more profitable by a large margin. Live service games tend to be online only. Networking doesn't play nice with massively parallel workloads, it simply doesn't make sense to make some kind of simulation that handles that kind of data and has to be consistent across multiple clients with latency between them (and if you just don't synchronize the simulations, you can't have the simulation be mechanically impactful). Ergo, this is a kind of innovation that mostly is gonna happen in singleplayer games and it's risky to invest a lot of money in those, especially for something experimental.

What you can actually deliver to multiple unsynchronized clients with GPU hardware is better graphics and simulations that don't have any mechanical impact (e.g. particle effects, cosmetic fluid simulation).

VR requires high resolutions at high frame rates, so it has been on the forefront of the tech. It's also very expensive so there are very few games developed for it.

[–] GeckoChamber@hexbear.net 2 points 1 hour ago

The shifts from quantity to quality haven't been as dramatic as something like open worlds for a while, but I do think there are some. You could argue that nearly photorealistic horror games are of a different kind. Better facial animations have allowed new types of storytelling, though that might have started a little before your time window. Maybe those games where you are always slowly squeezing between two rocks instead of having a loading screen could be seen as cinematographically new?

[–] hello_hello@hexbear.net 2 points 2 hours ago* (last edited 22 minutes ago)

GTA V/VI and RDR2 come to mind. Really I think it's just an issue of rushed deadlines that prevent any sort of detail from emerging so in the end, game studios just pump out machine up-scaled textures and pray that frame-gen solves everything for them. You can put as many shaders in your game but if the textures themselves lack detail it's just going to give off the illusion of depth.

Also chasing trends, Overwatch got to be super successful without any ultra-realism and it shifted the entire space to cartoony hero-shooters (+ fortnite) while the battlefields and cods languished behind and it made sense from a business perspective since the cartoon aesthetic cut costs from having to detail the textures.

When I see a large price difference between uber and Lyft i book a ride as a passenger in one and driver in the other and text the details to each party. It’s called arbitrage.

The paradox of evil has an easy solution.

Why does God allow evil to proliferate when they are omnipotent and omniscient?

Simple. If God existed, humans wouldn't even be like microbes compared to it. Do humans bother micromanaging* the lives of microbes to prevent evil (by the cultural* standards of the microbes)?

I know this "solution" to the problem basically side steps religion entirely and presents "God" as a hypothetical eldritch entity rather than the "benevolent patriarch" character of abrahamic religions. But it is food for thought.

*unexpected pun!

[–] hello_hello@hexbear.net 2 points 2 hours ago (2 children)

The paradox of evil is also just a very euro-centric thing based on non-pagan interpretations of god. As with any idealist paradox there are contradictory answers based on whichever perspective the speaker has.

God allows evil to proliferate to punish humans for making the wrong choice is just as valid as God is a collection of gases and doesn't have any impetus in creating anything based on belief.

[–] Le_Wokisme@hexbear.net 1 points 2 minutes ago* (last edited 2 minutes ago)

of course it's eurocentric, it's a problem for the euros because of the theological corner they backed themselves into.

you don't have to try to apply it to other cultures because they weren't worried about that shit and it would be absurd for the christians to even consider other theologies at the time and place.

[–] sodium_nitride@hexbear.net 2 points 2 hours ago (1 children)

I think the paradox can still exist for certain pagan religions. All it requires is the existence of an entity that is highly capable of managing humans and expected to be benevolent.

I also just realized this. But the paradox of evil applies very well to capitalist governments. The same arguments even apply, as well as the standard defense of rightists that capitalist government allow heinous shit to happen because "freedom".

I really like the Pachamama mythology of the Andean indigenous tribes since she can both be loving and sheltering but also cruel and destructive when she's hurt. Since she's tied to the mother nature and cosmos she exists wholly with everything and everything exists with her.

In a lot of ways it's a very proto-materialist reading of the world, where everything is related to each other.

Making a script that automatically pastes "(I'm not even going to try pronouncing that)" whenever I write an English word that is longer than ten letters. If this joke refuses to die dignifiedly (I'm not even going to try pronouncing that), I will kill it with my own hands.

[–] WokePalpatine@hexbear.net 2 points 4 hours ago (1 children)

This shmup called Flying Tank by some Czech studio has a small intro story about aliens coming to earth, humans are okay with it, and then the aliens somehow steal all the resources and terraform the planet for themselves. The world government later starts cooperating with the aliens for some reason. At best it's just a bad Half-Life-inspired story, but to me it seems like a bad right-wing take on immigration.

[–] WokePalpatine@hexbear.net 1 points 4 hours ago* (last edited 4 hours ago)

This reminds me of when the game Hellpoint had/has some Alex Jones/Nazi lore blurb about something. I can't remember what it was, but it was like a really specific conspiracy being referenced as a real in-game event and when asked about it they pretended to have no idea and had this weird evasiveness about it. And it's like, I know what you're doing here. No idea how right-wingers think they're being sneaky about this stuff.

Like I have nothing against guitars but holy shit there are so many other instruments and other styles of music

Nut Roast a lot of veggie/vegan people have one instead of roast fowl for thanksgiving/xmas dinner, They're pretty good my fam are mixed veggie/carnists so I usually have some, I admit I misread it as 'NuToast' at first lol I've never seen it written as one word before

Oh it's just a vegan meatloaf i thought it was some new thing

[–] ghosts@hexbear.net 8 points 8 hours ago (1 children)

Relatives have Thanksgiving parade coverage on and some little girl won a "golden ticket" to see some event show for free and she said "Um, I did that yesterday" and the announcer said "well now you get to do it again!"

And if that's not a commentary on US society I don't know what is lmao
