Alice and Bob are friends at ${university_name}. At ${date_time} they cross paths.

Alice: Hi, I want to tell you a TCP joke.

Bob: Sure, I'm ready to hear the TCP joke.

Alice: Alright,I am going to tell you the TCP joke.

Alice: Here's the actual joke. It's hilarious.

Bob: laughs hysterically

Alice: I'm glad you liked my joke.

Alice: Alright, that was the TCP joke.

Bob: Thanks for telling me about it.

Bob: So, that's it I guess?

Alice: Yeah, that's about all I wanted to tell you.

Alice and Bob part ways and run off to their next classes.

This is a really good way of explaining the difference.

Nah, tcp still yeats the baby, it just verifies that it was caught unbruised, or at all. If it wasn't that's ok. Try again. Yeet the baby's little sister

[-] InverseParallax@lemmy.world 5 points 1 year ago

You got that baby? Great, I'll send the next 500 much faster, tell me when you drop one and I'll slow down again.

So, UDP just sends it out there and anyone can intercept it?

[-] r00ty@kbin.life 2 points 1 year ago

No. Both UDP and TCP can be intercepted the same. The difference is that UDP sends a packet to an address. But doesn't have any in built system to check that it arrived, that it arrived intact or to resend if it didn't. There's also no built in way to protect against spoofing or out of order packet delivery. But generally implementations will handle the ones that are important of those themselves.

TCP establishes a circuit, packets are sent, verified and resent if required until the original data, in the correct order is delivered to the application. Also there is some protection against spoofing with sequence numbering. The downside is that time sensitive data might be delayed because of the retransmission and re-assembling. Which is why time sensitive streams like VoIP are usually sent over UDP.

Btw, on my device you sent the message -110min ago, not 110, -110

Welcome, traveler from the future

[-] r00ty@kbin.life 4 points 1 year ago

Yeah, this is a known interoperability thing between kbin and lemmy. So, I'm afraid I can't give you this week's lottery numbers ahead of time.

[-] Clent@lemmy.world 1 points 1 year ago

No. UDP is at the packet level. Interception is a different layer.

To use to today's language, UDP yeets the packets at you as fast as it can generate them.

It doesn't care if you catch any of them.

Don't yeet the baby.

[-] b3nsn0w@pricefield.org 1 points 1 year ago

actually, do yeet the baby if you have an application with different needs. for example, if you want to play a game, you're better off yeeting 60 babies a second and just hope that whoever is on the side catches enough of them to get a smooth stream of babies, than making sure every baby is handed gently to the next person and get the whole line clogged up the moment anything disrupts it. if you just use the yeetomatic 3000 you're always getting fresh babies on the other end, a few might just be dropped in the process

Wanna hear a UDP joke?

Nevermind, you wouldn't get it.

[-] netburnr@lemmy.world 1 points 1 year ago

"You might not get it"

[-] kira_ananta@lemmy.blahaj.zone -2 points 1 year ago

Yeahhhh I get the joke but I wish the meme didn't do it in a racist way. Why is the TCP baby white and the UDP baby not?

[-] Psionicsickness@reddthat.com 4 points 1 year ago

Please stop. It's not intentional. Stop basing your judgment on people and actions with an acute view of their skin color. Just see two sets of people. Thanks.

[-] igorkraw@lemmy.ml -2 points 1 year ago

Please stop.

In a world where there is racism, acting like racist themes don't exist only helps prolong it.

One set of of people here was drawn white (and responsible with a child), the other was drawn black (and irresponsible). That's worth critiquing, intentional or not.

Acting racist doesn't mean you are literally Satan, it means you are acting racist. Not stopping after people point it out and acting defensive and in denial is worse than thoughtlessly doing something racist, being told off and then correcting

[-] Llewellyn@lemmy.ml 3 points 1 year ago

You're the part of the problem.

[-] AnarchoYeasty@beehaw.org 1 points 1 year ago

Would you feel better about this if it was a stock photo of a white woman yeeting their baby rather than using a comic? A comic that the meme maker didn't create? Should the meme maker recolor the baby and woman white to make things better for you? This isn't racist because one of the meme images happens to be of black people.

[-] igorkraw@lemmy.ml 2 points 1 year ago
  1. Yes
  2. I don't care about who created it, the composition was done by the creator
  3. What is the line of "racist" for you? Before we argue this further, let's establish what is racist and what isn't
[-] bloodfart@lemmy.ml 2 points 1 year ago

Because udp packets are targeted for harassment by border devices like firewalls more often.

[-] randint@feddit.nl 1 points 1 year ago* (last edited 1 year ago)

I get your concern about this meme being racist, but not everything is about race. The stock photo of two adults passing a baby and the picture from a cartoon depicting a woman throwing a baby just so happened to be of different races. IMO that's not racist.
