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.

I love this. Thank you so much.

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.

That’s actually the topic of the talk! Around 1995-96, HTTP was picking up all kinds of use outside the academic community, and people were tacking extensions on left and right; one of the biggest was file upload support, which was done by throwing HTTP and email into a room and having them fight it out. Which is how we ended up with the monstrosity that is “sending emails over HTTP”, also known as “posting a form”.

The author of HTCPCP decided to codify some of his concerns with these, partly as a joke; I noticed long afterward that his joke was only standardized for coffee, which Personally Offended me as a citizen of a tea-drinking nation.

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.

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.

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.

I’ve just done some quick browsing to see if there’s a written-down motivation for Referer existing, and there’s this on the Wikipedia: “Many blogs publish referrer information in order to link back to people who are linking to them, and hence broaden the conversation.”

Which I guess makes sense, in the context of the original use of HTTP as an academic publishing protocol, but it’s gained cruft and nefariousness since wider adoption came about.

There are good arguments for stripping Referer from the standard, and yours is one of the most cogent; if Referer is still a thing in another 30 years, I’d be surprised.

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.

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.

There are joke RFCs almost every year, so it’s not unprecedented to add to the standards. This year, one of the additions was a Death Flag to TCP, to indicate when a connection is about to terminate. The RFC Editors are very approachable when it comes to the Apr 1st RFCs: a “real” standard would need to be drafted by someone actually in the field, but the Apr 1st’s are open to public submissions as long as you’re willing to redraft/edit in accordance with the documentation standards.

It’s worth noting that the Clacks header is an unofficial campaign, and hasn’t been standardised; the 'Pedia states that some 84,000 sites return X-Clacks-Overhead, and my own is one.

Out.

Can’t stand pineapple at the best of times, on pizza is another level of wrong.

Yes, obviously. Where else should it be at if not my pizza?

Getting really tired of this meme

Sheesh, some people have no sense of humour.

You’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.

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.

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
