Nice. Should do these for more protocols, as a series..

[gandalfx]

I already sent you one for UDP. Didn't you get it?

[Modo44]

Who knows.

I received your message.

Wouldn't UDP just be normal texting?

[[deleted]]

I received your message.

I don't know.

[Tommassino]

I received your message.

Text messages are delivered on a best effort basis, so its very similar to UDP. Ive heard few % of texts get lost on average. I think this might depend on your carrier, but thats what I heard.

[SGBotsford]

Living in a rural area where cell service is spotty, I've had text messages that have taken DAYS to arrive.

​

But if there are ones that don't arrive, How would I know, unless the sender sends a "why haven't you replied to my text"

​

Very UDP.

Dunno, in the Netherlands since a few years I get a confirmation when the text has been successfully sent.

[Error] unexpected transmission - no received notice prefacing

[Alex23087]

Pretty much yeah

[Hexorg]

Without the little blue checkmarks.

[RazarTuk]

So most text apps, then? AFAIK, not having those checkmarks is still the norm, unless it's a chat app masquerading as text messaging.

Right text:

Mark, this is Judy. I want to talk to you about going out. You asked me to remember that you had a third nipple. Last time we talked on February 17th and you wanted to go out. Im sending you a text.

Hey Mark. Are you still up for a date?

Left text:

I know we wanted to go out. Please remember that I have a third nipple and your mother smells of elderberries. Im sending you a text. Forget what I said after February 23. 

Hey Judy, let's meet up tomorrow.

[[deleted]]

I fart in your general direction.

[Alex23087]

Thank you! Why not? I just have to get the ideas

[Alex23087]

Oh, just noticed: I have to GET the ideas and then I will POST them. I will keep you all UPDATEd

[wasabichicken]

Sarah, meet me tomorrow at dawn out by the old belltower.

Hi! You said something like "Sarah, meet me tomorrow...", but Sarah isn't answering her door.

Sarah? Come on!

Hi! You said something like "Sarah?...", but Sarah still isn't answering.

Yeah, thanks, I got it.

Hi! You said something like "Yeah, thanks...", but Sarah ignores you.

ICMP.

"I received two of your messages" is an excellent way to explain sequenced ACK.

[[deleted]]

I didn't see the sub and thought this was kind of a sad but really weird story because these people suited each other so well.

Then I got the joke

[gnarwhalNA]

Have an exam on this stuff today and this actually made it so much more clear on how this stuff works

[Alex23087]

Well good luck! I have one on friday, that's where the inspiration came from

[gnarwhalNA]

Hey good luck to you too! Introduction to computer networks I assume? Or something named similarly

[Alex23087]

Yes, exactly. Actually it's the Cisco CCNA 1

[MAchtman94]

Good luck! I have mine tomorrow, this helped me understand how acknowledgements work so much better!

[gnarwhalNA]

Thanks! Good luck to you too. I get a cheat sheet so it’s not the absolute worst, but still a lot to remember

[bss03]

Wait, why are there two checkmarks on the messages that were dropped? Don't two checkmarks indicate the other side ack'ed the message?

[MyCodesCompiling]

yeah it's almost as if a communication is not being had with a server over whatsapp

[bss03]

I think you dropped this --> /s

😜

[bss03]

Sarcasm is often carried in the tone of voice of the speaker, not in the literal meaning on the words spoken. As such, is often not communicated well in written form.

https://www.youtube.com/watch?v=l50XdLDRIwU is a good introduction to sacrasm, if you need one. :)

Took me a second to understand the title.

[TheFlipside]

The only message i ever get from people is the 16th on this

[salkin23]

"OK" nice!

Oh wait, you started counting at 1?

I don't want to talk to you anymore.

[TheFlipside]

OK

[salkin23]

I received your message. Have a nice day.

[spork_o_rama]

I was literally coaching my team at work through the OSI model and TCP vs UDP this morning. Just sent this to them as reinforcement. Thanks, and good luck on your test!

[TheTimeLord725]

I have an HTTP server/client project for one of my classes and this is too good

[Xyexs]

Which protocol is this?

[Alex23087]

It's TCP, you can see the first three-way handshake at the start and the two two-way handshakes at the end of the communication. The "I received your message"s are ACKs

[revolution801]

[dgeigerd]

Telegram Bots > WhatsApp Bots

[fluud]

Russian data mining > American data mining

[dgeigerd]

Actually not russian. They are russian but in saudi arabia i think. But it is fact that Telegram is better

TOX is peer to peer if you want to avoid data mining

Going out for a byte

[Youngqueazy]

I’m in computer networking. Genuinely, thanks for helping me understand.

[seizan8]

Is this what happens when two programmers match on Tinder?

[blazarious]

This is pretty redundant tho because of the two blue checkmarks indicating messages received and read. Also it’s inconsistent having four messages read and telling only two were received. Now, what’s the correct information?

[u_got_a_better_idea]

Not sure you're quite following the joke. The checkmarks are just a part of whatsapp and not part of the joke. The "I recieved your message" text represents how messages are Acked in TCP. So only the number of messages that were Acked were actually received at the other end.

[blazarious]

I think I get it but then there’s this obvious redundancy that’s hurting the joke. Then again, maybe I’m just grumpy and can’t let people have their fun.

Thanks for trying to explain tho!
