What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Even biological code can compile randomly at times!

It's all massive spaghetti code too, including spaghetti wiring. Terrible cable management.

A giraffe has a vein or nerve that goes all the way up to its head for zero reason.

It's incredibly inconvenient and difficult, but it wasn't before their necks were absolutely stupid.

[–] emmeram@lemm.ee 27 points 4 months ago (3 children)

That would be the laryngeal nerve. It’s been with us vertebrates for a long time.

I take your, “for zero reason,” to indicate that it’s silly that it’s so long in a giraffe. And it is, because it connects the larynx and the brain, two bits that aren’t very far apart. You’d never design it that way from scratch.

But the laryngeal nerve’s length has a reason: it loops around the heart and it developed in our fish-like ancestors. At that time, it wasn’t silly for the nerve to wrap around the heart, because fish don’t have necks and thus the nerve was about the same length whether it wrapped around the heart or not. As necks developed, evolution found it easier to lengthen the nerve than to reroute it. So here we and giraffes both exist, having much longer laryngeal nerves than you’d engineer if you were making us from scratch.

Yep, evolution doesn’t get do overs.

[–] nickwitha_k@lemmy.sdf.org 2 points 4 months ago (1 children)

In a way it does. Just ask crabs.

[–] RizzRustbolt@lemmy.world 2 points 4 months ago

Fookin' casuals...

[–] Plopp@lemmy.world 1 points 4 months ago

So here we and giraffes both exist

Source?

The issue is that it traverses the neck twice, going all the way down from the brain and all the way back up to its endpoint.

[–] naught101@lemmy.world 1 points 4 months ago

Yeah, I got it. Was just commenting on the poetry of the sentence.

[–] delirious_owl@discuss.online 9 points 4 months ago (1 children)

Your "good cable management" would be terrible for cooling. These cables are multipurpose, and their spaghetti flow is a feature.

"you're telling me ALL of the wiring for the most important fingers goes through one tiny, fragile hole?"

[–] RedAggroBest@lemmy.world 3 points 4 months ago

Not really that fragile, you (generalizing for most of Lemmy) just put excessive strain on it by sitting at a desk and using a computer.

The other big one is brachial impingement because you all slouch and your shoulders get so fucked up they pinch the nerve for 90% of your fuckin arm.

[–] RizzRustbolt@lemmy.world 4 points 4 months ago

Can't pull them out.

They're ziptied.

[–] designatedhacker@lemm.ee 22 points 4 months ago (1 children)

You saying they might have an unexpected dangling pointer?

[–] zeroday@lemmy.blahaj.zone 1 points 4 months ago

Yeah, as I commented elsewhere, I'm damn impressed my code managed to compile and run. I guess life has a pretty fault-tolerant compiler at times, or maybe I was just super lucky to not have the errors be in spots that'd completely screw me over.
