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.
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?
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.
Are you tingly anywhere?
Not a question, but we use 418 in production! We have a nginx router that routes pages based on its path to either old frontend or new frontend. I wanted some easy way to handle the routing (and to not repeat myself), so I set the new frontend as a handler for 418 error and then just return 418 in the nginx for any page I want on new UI. I chose 418 because the others could be actually used by the old frontend and it could get all weird.
This is actually a good use of 418 in production, and one I’ve come across before: if you need to perform some custom handling and throwing a HTTP error is the only sensible way to do it, 418 is always available.
Unless your server really is a coffeepot, which is …unlikely.
Getting more likely with each passing year.
What’s the most impactful 418-related incident you’ve witnessed? I remember a few years ago npm went down and was returning 418 which spawned jokes and chaos across the web
The incident you mention is probably the most impactful, but there’s also the time the Russian military blocked IPs outside Russia by returning 418 instead of the more logical 403.
I know russian a bit and jargon for russian word “teapot” is also commonly used as “dummy” or “novice”. 418 for foreigners might have been on purpose there which brings Your April’s fool joke to a nation wide level :)
Yeah, I’ve seen people refer to this as the “fuck off” of response codes, especially during that incident. How does that make you feel?
It’s not up to Mr Masinter or myself to police the usage of anything defined in the standard; if people feel like being assholes regarding the issuance of 418 errors, at least they’re being whimsical assholes.
Could be worse; could be 200 with an error message inside, negating the entire point of error codes. I see that all the time.
Yeah, GraphQL has adopted this practice as a standard and it’s kind of sad.
When I was fixing up a legacy API app at an old job, I realized they did exactly that. I cleared it with my boss and started fixing up our error codes - pretty much all 401, 403, and 422. This blew up an integration with another app that literally threw exceptions on those codes rather than handling them. I died inside as it was my first software dev job. My first rollback of a change as well.
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!
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.
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.
Well there is really only one question…
Pineapple on Pizza?
Yes, obviously. Where else should it be at if not my 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
What’s the funniest legitimate non-joke standardization detail you’ve come across?
I enjoy that the original draft for the Referer header spelled it wrong, and now we’re all stuck with the typo forever…
Can someone elaborate on this please?
Edit: oh jeez. I’m so used to reading “referer” I didn’t even realize it was a typo.
I’d be happy if we’d just accepted “referer” as the correct spelling for everything, but instead we have the “Referrer-Policy” header, so now I need to check the correct spelling for anything involving referring…
I do sort of like the idea that because we want to keep backwards compatibility on software we just change the language instead since that’s easier.
I don’t have any questions but holy shit this is so cool.
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
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!
A new RFC for IPv7. It’s just IPv4 with an extra octet. Yes or no?
I don’t think the extra address space of IPv6 is the problem holding back its adoption, so “IPv4 with another octet” would likely run into the same issues.
Not that it’s a bad idea, it’s just an idea that’s unlikely to catch on.
What would you say is holding IPv6 back?
The biggest problem IPv6 has is that IPv4 has been so hugely successful: gargantuan resources have been poured into getting the world connected on IPv4, and the routers/etc deployed in the field (especially in sub-Saharan Africa, south Asia, and other places which got the Internet late) are built around version 4: data paths 32 bits wide, ASICs and firmware developed with 4-byte offsets, and so on.
It’s a big effort, and more importantly an expensive effort, to move all that infrastructure over for what the end user perceives as no benefit: their websites load just the same as before.
Are you saying there’s no financial incentive at the individual level to upgrade?
Essentially. If the end user is being asked to make a financial outlay to get to the same things they did before, it’s unlikely that will go down well.
You can unilaterally create another status code. What do you create?
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.
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’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.
