I like returning 418 instead of 404 or 403 on the files the script kiddies are hunting for on my web servers. I'm sure it does nothing but I'd like to think I've wasted some of their time at least once.
Fun fact, first webcam was a series of updating stills of an actual coffee pot so some engineers would know if there was coffee made.
With that, plus image recognition, plus a control system, you could use rfc2324 to implement the digital control side
Though I think I'd use weight, temperature, and flow sensors for easier service implementation
And then plug those values into a image generation service to give users a visually intuitive way to see if there's cooffe or not!
420 is still avalable. Not sure what you would put there ("Server too high?") and given the controversy over 418 I think its best to leave that one blank instead of making a weed joke.
There was an attempt by Twitter at one point to use "420 Enhance Your Calm" as a code to indicate you're being rate limited.
200: "I gotchu, bro. Here you go. Have a good day."
401: "You're not on the list. Get lost."
402: "Pay me or get lost."
403: "Everyone get lost."
404: "You are lost."
500: "Ooopsss."
501: "Knew I forgot something..."
504: "I can't do this shit all day."
401 is "I don't know who you are. Get fucked"
403 is "I know who you are and you're not allowed here. Get fucked"
502: "I'm fucked, you're fucked, but most of all the developer trying to solve this is super fucked."
401 is more like “Tell me who tf you are or get lost”, while 403 means “You're not on the list, get lost”
Surprised no one's mentioned HTTP Cats yet:
Personally, HTTP 405 (Method not allowed) is my favorite:
As a software developer / network admin, all of these are almost always "I fucked up configuring the web server".
These are pretty good as an overview tbh. I like it when teachers have a sense of humour at least.
