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!
I had been an advocate of getting just an ordinary person to do the first Lemmy ama but apparently we’ve got an absolute legend.
Have you ever had a favourite reference to your joke come up?
I did go to a conference once where they were handing out laptop stickers, and in the pack was a 418 teapot.
Of course, a week after I stuck that to my machine, it died. Telling the laptop it was a teapot didn’t agree with it, I guess.
How do you feel about 418 being included in many legitimate http libraries?
It’s great: the Internet should have a bit of that sense of whimsy, and knowing that there’s official support in many libraries for “you’re asking me for coffee, but I’m a teapot” is one of those things that gets me through the day.
Ironically, it’s a cup of coffee that gets me through the day
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.
http.cat was absolutely critical when I transitioned from general application development to web backend development. Not a joke, it was just a super readable site listing the codes with a short and memorable url.
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 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.
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
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!
I need an ELI5 for this I’m a stupid Gen Z
You know sometimes you click on a link and it says “404 not found?” 404 is an HTTP status code. basically when you click on a website your browser makes an “HTTP request” to that website to get the web page, and it’ll respond with a code to tell the status. 2xx is ideal, since it means OK. 4xx means it’s an error on your end. (404, you requested a nonexistent link.) 5xx means it’s a server error.
This person made 418, a status code for “I’m a teapot”. It was intended as an april fools joke but it’s used sometimes for when the server doesn’t want to handle a request from the client.
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!
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.
Someone tested the evil bit and found a selection of real-world networks that react to its presence
Fun read, thanks for the link!
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
What’s wild is that IPoAC was actually tested, and shown to have a higher throughput than the local ISP. Source
Relevant what if: https://what-if.xkcd.com/31/
There really is an xkcd for everything…
Wow. Never knew about these :)
I don’t have any questions but holy shit this is so cool.
Well there is really only one question…
Pineapple on Pizza?
Out.
Can’t stand pineapple at the best of times, on pizza is another level of wrong.
Hear hear
Getting really tired of this meme
Yes, obviously. Where else should it be at if not my pizza?
What a fun AMA topic lol. I dont have a question, I’m just glad youre here, spreading the good gospel of your goofy internet standard
What’s the process for submitting RFCs? And how do they pick which joke RFC they’ll publish? That’s a meeting I’d like to be a fly on the wall of
For “real” RFCs that aren’t Apr 1st jokes, there’s an independent submissions track for the public to write Internet-Drafts and then submit them into the review process.
With the joke RFCs, they get emailed straight to the editor at least two weeks beforehand. I’m not privy to the selection meeting, but I expect it’s fun.
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.
It’s because of the very impassioned speech by then-Senator Ted “Tubes” Stevens, where he demonstrated that he clearly had no idea how any of it worked. You could hear the lobbyists in every bit that he parroted, without absorbing it. He also had formed a strong opinion already, despite clearly having just been told how it works.
It’s not that it’s a bad analogy. It’s that it’s (somewhat) reductionist, and most famously associated with an idiot.
I loved sharing this with my senior who hadn’t seen it before, and it gave our small team a Ggod chuckle one afternoon. Thanks for your creation.
With the absence of a crystal ball, but with excellent inner knowledge, what future standards could you see being implemented in the next 10 years for internet?
As it turns out, one of the Apr 1st RFCs for this year covers AI Sarcasm Detection, but I can see more serious protocols arising for the transfer of AI model data and/or training procedures in the coming years.
I’d also hope ActivityPub reaches Internet Standard level, though it may fall outside the IETF’s scope of operations.
Congratulations on creating such a cool piece of Internet arcana!
What do you think the silliest/most useless response status code is aside from
418?Were there any codes you wish had been included that haven’t been for some reason?
I always rather enjoyed the double entendre of “420 Enhance Your Calm”, which was an unofficial response from Twitter’s original API before “429 Too Many Requests” was standardized.
But I can’t think of any codes which aren’t already in there, that I’d use; there are a bunch that don’t see much use, like “410 Gone”, so the list could do with trimming down if anything.
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.
