As someone who has experienced Post graduate biology, at that point explaining some things does reach the level of "trust me bro" when speaking to people that have no baseline biology knowledge.

Do you want a series of 1 hour lectures and a few thousand pages of reading material? No? Then you just need to trust the experts.

I'll settle for some unlikely and interesting bits out of context, such as the existence of single-cell dogs.

17

I'm not a biologist myself, so this explanation might be full of errors, but the gist of it is:

A dog got cancer. Cancer tissue is a part of your body with the same genetic information, just growing uncontrollably, right? Well, one of the cancer cells got separated and somehow learnt to survive on its own, reproducing asexually and started a lineage of a new single-cell organism that still exists to this day.

This single-cell organism has the same DNA as the dog. Genetically speaking it is a dog.

Most people don't?

I mean why would anyone not studying biology (or related fields) have to take biology in college? Or is that a US-American thing?

lemmy.world

It's a common general education requirement for college in the US, yeah. Biology, physics, psychology, economics, English/writing, math, etc. are often all required, or at least a selection of most of the discipline-intro-level courses is.

16

Huh, that's weird. Isn't highschool sufficient for general education?

Thinking about it, it might not be. I've just checked and at least in Germany a US highschool diploma (including passing tests like SAT or ACT flawlessly) doesn't (generally) qualify you for entering university here. That is, you are literally prohibited by law from enrolling.

I'm genuinely glad this isn't part of university education here. I mean, I'm attending lectures because I have interest in a certain subject - not because I want even more general education after finishing secondary education.

It really isn't, it's the scientific term for a feature in a whole bunch of animals...

Like holy shit context matters, and I don't mean that in a "it's fine if it's not meant as an insult" way, because people have a right to ask to not be referred to a certain way regardless of intent.

But also the tumblr links ask me to log in so I can't tell if they would reveal this as sarcasm or they have an actually convincing argument.

16

It's been used as a slur against intersex people since medieval times, before someone decided to use it to talk about slugs and shit. You would know this if you actually listened to intersex people.

2

It's not a slur when used in proper context, and also are you really trying provide a random tumblr post as source?

I assume you mean the "h" word I used. If that is a slur than I apologize, I did not know. It is a common industry term for genderless electrical connectors.

4

I appreciate your civil response. So, this word has been used as a slur against intersex people (people born with or who in puberty developed genitalia or sex charasteristics differing from the concepts of 'male' and 'female') since the middle ages and has had a long history of violence, such as forced genital mutilation and infanticide, behind it. It often is conflated to mean someone or something possessing both a penis and a vagina, who is typically capable of both impregnanting and becoming pregnant. (it should be noted that this does not occur in humans without body modification!) Because of this, the h-word was later (19th or 20th century iirc) used by scientists to describe cosexual animals and plants because someone was too lazy to come up with a new term that didn't have truckloads of baggage attached to it. Thus leading to what we're talking about.

stephan262reply
lemmy.world

I quite agree. Personally I use Main/Secondary, I find it does away with the problematic terminology while needing no changes in acronyms.

10

Eh, I think master is used (AFAIK) unproblematicly in other contexts like a master key, recording master, and master pattern. Converting it to "main" seems like a change or loss of meaning, but the problem may be that there is not really a consistent meaning across electronics usage to start with. I think "secondary" has some connotation of filling the same purpose or type as the primary, which doesn't really fit for m/s usage. Master/sheep is my most similar option that keeps the "m/s", but it feels awkward enough to draw attention to what it replaces. Could just do master (or main) and sub, where "sub" could mean substitute, subordinate, subscriber, [submissive,] etc. as needed.

7

I think it would be less of an issue if human slavery and all its attendant and resultant issues were actually firmly a thing of the past. It could become a "clinical", accurate way to describe technical constellations where one component is strictly subordinate to another, if it didn't have the connotation of ongoing human rights issues.

Not saying it's the best or the only option for the terminology, just wondering aloud whether the callback would be an issue if the topic wasn't still so raw and sore.

hot damn. I once lived in a house that used a contraption like this to feed elctricity from one circuit into another. I didn't know and I touched one end... I did fall off the ladder, but I'm still alive.

Of course this analogy is even more flawed than OOP's.

Can I ask, what's the (ill-advised) use case for this?

I don't know anything about electronics but I readily believe this is a dangerous cable

But what I don't get is what people want it for. I've never been in a situation that calls for this

They can be used to hook a generator to your house if your power goes out, but people will use them for things like if they strung up Christmas lights backwards so 2 female ends are next to each other.

10

It allows you to move power from a live circuit to a dead one by connecting the outlets between them. The most common use I've seen is to easily hook a gas generator to a household circuit during a blackout.

But yes, they're very dangerous and there are less-stupid ways to hook up a generator that won't make tripping over a power cable lethally dangerous or risk burning down the house by bypassing the circuit breaker and overloading the wiring in the walls.

But this one is popular because it can be done very quickly and easily with minimal supplies.

9

they exist and my coworkers kept buying them from somewhere and I never trusted them not to kill themselves so I did the one underpaid above and beyond the boss didn't deserve by fixing the idiotic wiring

5

When I was a kid our electricity got cut (yes we were poor). We found an outlet with power for some reason. Must've been wired to another unit in the 3 family home.

So my moms boyfriend went out to the hardware store and made this cable. Then plugged in the working outlet to a nearby dead one and we got power again...

I don't remember how long we ran that but nothing exploded.

If I recall he was from another country and they did this all the time across houses when someone lost power or hooking up gas power generators.

Another example where this argument falls flat is spaceship docking connectors, which are genderless so they can all dock to every other one.

In space being heteronormative is less useful.

35

Unfortunately, it's difficult to find a good shot of the docking adapters in nomal docking videos. Scott Manley has a bunch of good shots in this video, and I found this fantastic video showing the docking process in detail.

Or read the wiki on the International Docking System (IDS), or spacecraft docking systems in general.

Unfortunately, the IDS isn't androgynous right now, the passive and active sides are slightly different. Androgyny is planned for a future version.

I think that's for token ring. I remember using an adapter to plug Ethernet into a wall version of one of these. Massive things.

So it's just a fucky old school data connector? That actually makes some sense, given how old Ethernet cables are these fuckers probably date back to when ribbon cables were the standard for connections, like that bastard radio shack computer from 1979 that I have.

Actually, these token ring connectors were introduced in 1984. Twisted pair ethernet was introduced in 1986. Though, coaxial BNC was more popular until the mid 90s.

3

Yeah, in my case the building had originally been fitted for token ring, and eventually was retrofitted for Ethernet, but instead of swapping out all the hard wired wall ports, they just issued that socket to ethernet adapters. The rooms ALSO had BNC ports, which weren't live anymore.

Old Czechoslovak oval 380V (3-phase 220V) plugs have 4 genders. The contact gender depends on whether the receptacle is a power source or sink, the sleeve gender depends on whether it's a cable mount (innie) or wall mount (outie). I hate this, they could have made it work with two while still keeping the water resistance flaps like the new CEE round ones.

This meant that people needed contraptions like this to extend cables:

We have a homemade one with a dodgy wooden base, and two outputs: one has two phases swapped for counterclockwise power.

I have read a bit about biology and the science is kinda clear cut on it. That is to say, sex is a false dichotomy. Not even the chromosomes are a deterministic 100% guarantee for other things like genitals, breasts and even "male/female normatieve brain patterns". So yeah, follow the science and discover biology is not binary.

snails are hermaphroditic, impale each other with sex arrows, and then proceed to twist around each other while hanging from a rope of slime and they impregnate each other.

Jellyfish spew their sperm and eggs into the water around them, hope for it to meet up and make an egg that hatches into a larva, which roots itself to the ocean floor and grows into a polyp where the adult jellyfish grow like a stack of plates and each one individually buds off.
