Let’s get the AMAs kicked off on Lemmy, shall we.
Almost ten years ago now, I wrote RFC 7168, “Hypertext Coffeepot Control Protocol for Tea Efflux Appliances” which extends HTCPCP to handle tea brewing. Both Coffeepot Control Protocol and the tea-brewing extension are joke Internet Standards, and were released on Apr 1st (1998 and 2014). You may be familiar with HTTP error 418, “I’m a teapot”; this comes from the 1998 standard.
I’m giving a talk on the history of HTTP and HTCPCP at the WeAreDevelopers World Congress in Berlin later this month, and I need an FAQ section; AMA about the Internet and HTTP. Let’s try this out!
You must log in or register to comment.
Thank you for fixing a critical flaw in the original RFC.
What did you think about the Save 418 Movement? Were you involved in it in any way?
My endorsement is at the bottom of that page, in fact. I wasn’t an active campaigner, but a word in favor was the least I could do.
Oops, RTFM. Well, thanks for fighting the good fight with the power of your reputation.
I need an ELI5 for this I’m a stupid Gen Z
I need one too and I’m a stupid Gen Y
As a late millennial and a programmer, I’ve got you.
So when you request a web page, before anything else, the server gives you a 3 digit status code.
100s means you asked for metadata
200s mean it went ok
300s means you need to go somewhere else (like for login, or because we moved things around)
400s mean you messed up
500s mean I messed up
So this is in the 400s. Each specific code means something - you’ve probably seen 404, which means you asked for a page that isn’t there. And maybe 405, which means you’re not allowed to see this
418 means you asked for coffee, but I’m a teapot
I can’t say enough how amazing your explanation was. Im not a programmer but I have worked on websites (self taught) and I never knew this. Thank you!
I just found out about this on Brodie Robertson’s yt channel! I am not a teapot btw!!
Haha, same here! I was so proud I knew what the title was referring to before reading the post. Lol
Glad to hear it, you should walk around with a HTTP 418 hat so more people know you’re not a teapot.
But then people would think they are a teapot
Every once and a while I’d just like to see 200 get some love, but no. It’s all 404 this, 502 that.
I’m just “OK”. It’s like being the middle child of response codes.
200 is probably the most common status no? Many successful responses will give 200 in the backend
OK
username checks out
Do you regret adding it, or with the knowledge you have today, would you still add the 418?
Since a bunch of languages have not implemented it, or/and has long discussions about it:
https://github.com/dotnet/runtime/issues/15650
https://github.com/golang/go/issues/21326
https://github.com/nodejs/node/issues/14644
https://github.com/psf/requests/issues/4238
https://github.com/aspnet/HttpAbstractions/issues/915You’d have to catch up with Mr Masinter to get his opinion on adding error 418, I’m afraid; that piece of the business wasn’t my work.
I’m happy it’s there though: it may have sparked flamewars, but at this point what hasn’t. It does bring somewhat of that sense of humanity to the whole enterprise of working on the Internet.
I remember when I first learned of error 418 and it did really help me understand that the Internet as we know it was made and shaped by regular people with senses of humor. Helped make it seem a bit less daunting/intimidating to understand.
It reminds me of how the Network Port 666 is specifically reserved for doom, always love Easter eggs like that in officially used protocols.
I’m just finding out about this trivia now but I’m a big fan
I remember when I learned about this, I was working on an absurdly large project on my own. I was lost in all the details and losing hope of ever finishing. I was working on the backend API when I learned of this and took the time to implement the 418 response. It felt silly and brought the fun back to the project.
Sheesh, some people have no sense of humour.
Personally I don’t have any problems with it (if that was directed at me) - I’ve added 418 as “unhandled exception code” response to a bunch of applications, so I can easily differentiate whether my application is throwing an error, or whether it’s some middleware gateway AWS io-thing
I was just curious what OP thought about it, since in the early days it wasn’t uncommon to add goofs or easter-eggs into software, but nowadays not done so much… and apparently the “HTTP Working Group” doesn’t like it either… So I was curious whether OP though in hindsight whether it should’ve been added or not
How can it be unhandled? It’s right there in the song, just before the spout!
What other such joke standards (by you or others) do you like?
A little lower down the stack, I always liked the Evil Bit in TCP, a standard which removes all need for firewalls heuristics by requiring malware or packets with evil intent to set the Evil Bit. The receiver can simply drop packets with the Evil Bit set, and thus be entirely safe forever from bad traffic.
At the physical interface layer where data meets real life, I especially enjoy IP over Avian Carrier; that link in particular is to the QoS definition which extends the original spec for carrying packets by carrier pigeon.
With the advances on SDcards, IPoAC is getting better and better.
As the saying goes, “for bandwidth, nothing beats a truck full of
tapes1TB MicroSDs hurtling down the highway”.
The Evil Bit sounds like the real Do Not Track header field
Wow. Never knew about these :)
Someone tested the evil bit and found a selection of real-world networks that react to its presence
I am interested in writing a real RFC, what kind of mailing list etc should I join in order to make my RFC real?
I just found out about this on Brodie Robertson’s yt channel! I am not a teapot btw!!
I have no questions, but I want to let people here know that there are two excellent websites related to this: http.cat and http.dog, for looking up HTTP status codes.
For an example, if http.cat/418 doesn’t brighten your day, I don’t think there’s much that can.
I love this. Thank you so much.
You’re welcome! I try to share this with people whenever I can, hoping that it makes someone’s day better. It certainly gives me a lot of joy when I can respond to something with a relevant http cat, though the few people I do it to might be getting a little annoyed.
What’s your take on the fediverse frontier?
I think it’s excellent out here. I was stuck on Reddit for the longest time, and this recent debacle has pushed me to explore the networks at the edge; this feels a lot more like the Internet of old. The analogy of email is apt, I think, with the accounts on multiple servers and the interplay between.
You awaken my nostalgia, curiosity and sense of adventure when you say “explore the networks at the edge”. Are there any other networks than lemmy / mastodon that you would suggest checking out?
Are you tingly anywhere?
Internet Relay Chat’s been one of those things that’s always felt out on the edge. I’ve been on EFnet since perhaps '03, and it’s a lot quieter than it was…
With people moving en masse away from the centralized sites and their Firebase-implemented chats, we may see a pick up in traffic on the IRC networks, which would be good to see.
What are some interesting channels on EFnet? I basically grew up on Foonetic, but moved to Slashnet when #xkcd did. I don’t pay near as much attention to IRC as I used to, but would like to change that
I haven’t been exploring in the depths of EFnet in …many years. I’m confined to the programming-related channels I found in the Way Back When, nowadays: at the moment, #c is probably the most active and it’s almost all old-timers.
You can unilaterally create another status code. What do you create?
Wasn’t there a new HTTP action recently proposed for “This is a JSON RPC request that we’ve convinced ourselves is actually REST and we’ve been using POST and someone finally pointed out that that was stupid”?
Not a new status code but still vaguely amusing.
I quite like the idea of HTTP 256 Binary Data Follows, which is just 200 OK but you asked for a non-text content type file.
Are you by any chance, British?
Did the predilection for tea give me away?
What a British thing to ask. Very apt sir, very apt.
I’ve heard that the internet is a series of tubes.
Can you confirm?
I never understood the beef people had with that. The Internet is a series of tubes, of various widths and sizes, with inputs at random points in the stream.
Plumbing analogies are apt.
Was RFC 7168 written with Captain Picard’s tea Earl Gray, hot in mind? If not, are follow up modifications planned?
So replicators are kind of a special case: they can make anything already fully prepared, without the need for a brewing command to be sent. It’s possible that by the 24th century, there’s a compatibility layer between Replicator Intermediate Language and HTCPCP, but I’ll leave that to future generations to establish.
I’m actually going to that conference! What’s the title of your talk? I’ll be sure to attend it!
Excellent. I’m on Stage 4 on the Thursday afternoon: “Brewing Tea Over The Internet”.
Should be fun times, see you there.
