The theorem has been expressed colloquially as “you can’t comb a hairy ball flat without creating a cowlick” or “you can’t comb the hair on a coconut”.
A hairy doughnut … on the other hand, is quite easily combable.
What gives someone the right to speak like this. You think this is the kind of factoid I can just forget?? No, this meme is going to jockey my brain until the day I die.
Like a chicken?
“CHICKEN JOCKEY!”
throws popcorn at phone screen
Shave 'em. I don’t want no cowlick near my balls
You haven’t lived until a cow licks your balls.

Why does Wikipedia do this?
Whoever posted the link was on mobile at the time and didn’t feel like deleting the m. after copy pasting.
Yeah ik. Just confused why Wikipedia itself does it
Does what? Have a separate site for mobile viewing? There’s many good reasons…
Why encode it in the URL.
How else do you do it? Cookies? JavaScript? That would be terrible.
Responsive design usually doesn’t require detecting anything about the client. There’s probably some differences in actual HTML markup between mobile/non-mobile Wikipedia, but I’d be surprised if it has to be that way. Media queries have been available for a long, long time.
read the user agent when u visit the link like every other site ever
It would be better to handle it by detecting what device you’re on rather than having encoded into the url. That way it wouldn’t matter what device the page was shared from.
That’s a terrible idea. Because many users change their user agent for security.
No, you can’t expect to detect what devices someone has. That the thought process of an inexperienced dev.
They already do this to redirect from the desktop view to the mobile view so they could do it the other way but don’t for some reason.
If a user changes their user agent to something that would cause a site to not be able to determine whether they are on desktop or mobile then they can expect that some sites aren’t going to work well.
usually it is just a redirection. One of the reasons wiki does this is that their stack is more older device friendly (for the most part, you can use wikipedia perfectly fine without any js), and having a daptive view usually requires js (there are some other ways too), but wiki is constrained. So when browser recieves a request from a mobile user agent, they just redirect to mobile site.
Responsive design usually doesn’t need JS, it’s mostly pure CSS.
Its not just old devices. I turn js off for security. There’s a whole class of high-risk users that this is for. Even on modern hardware and software.
