Welcome to Programmer Humor!
This is a place where you can post jokes, memes, humor, etc. related to programming!
For sharing awful code theres also Programming Horror.
Found this in the depths of my storage. Not sure where its from but might improve the day of some people ^^
Network monitoring engineers: explains for the umpteenth time that a node reporting down isn't just a single dropped packet
Geez...we all have learning experiences but I feel node down and packet dropped should be a clear distinction in the mind of anyone in IT...but people will surprise you
It's actually panic in both
May I interest you in using unwrap_or instead of unwrap
Packets are lost all the time. Especially when uploading or downloading.

I also remember someone posting that article
Not a bad price if the service is any good
This is wild. Didn't knew gangs do shit like this.
Hello, would you like to hear a TCP joke?
Edit: since no one is biting here’s the full joke
"Hi, I'd like to hear a TCP joke."
"Hello, would you like to hear a TCP joke?"
"Yes, I'd like to hear a TCP joke."
"Ok, I'll tell you a TCP joke."
"Ok, I will hear a TCP joke."
"Are you ready to hear a TCP joke?"
"Yes, I am ready to hear a TCP joke."
"Ok, I am about to send the TCP joke. It will last 10 seconds, it has two characters, it does not have a setting, it ends with a punchline."
"Ok, I am ready to get your TCP joke that will last 10 seconds, has two characters, does not have an explicit setting, and ends with a punchline."
"I'm sorry, your connection has timed out. Hello, would you like to hear a TCP joke?"
H ll wou d l k o h ar a UDP j ke?
Sorry I only do udp, but I won’t tell you that
would you like to hear the udp joke? you might not get it, but I don't really care that much
This was better than mine
Sure, but we need to shake hands first.
I will now start transmitting the TCP joke.

Mr Krab there surely doesn't have the same customers I have, if he's so relaxed
To be fair, because of window size management it only takes 1% packet loss to cause a catastrophic drop in speed.
Packet loss in TCP is only ever handled as a signal of extreme network congestion. It was never intended to go over a lossy link like wifi.
On the other side of the spectrum packet loss is a key feature of some of the layers below tcp, like path-mtu discovery.
Doesn't wifi have its own retrial protocol? It's been a long time since I've read the standard, but I think it's almost lossless from the POV of TCP.
None built in from what I recall. That was from back in 2011, so it's possible things changed since.
Reading through, it looks like retries do exist, but remember that duplicate packets are treated as a window reset, so it's possible that transmission succeeded but the ack was lost.
I remember the project demos from the course though - one team implemented some form of fast retry on two laptops and had one guy walk out and away. With regular wifi he didn't even make it to the end of the hall before the video dropped out. With their custom stack he made it out of the building before it went.
I'll need to dig through to find the name of what they did.
I believe so, yes. Every 802.11 frame is effectively ACK'd. Makes a mockery of OSI layering, but so does everything else.
