Other niche HTTP codes:
420: Enhance Your Calm (used by twitter to rate limit clients, reference to cannabis culture)
451: Unavailable due to legal reasons (now an official code! reference to Ray Bradbury's Fahrenheit 451 in which books are illegal)

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

"Enhance Your Calm" is official as well, it's a HTTP/2 error code.
Pretty sure it's primarily a Demolition Man reference.
Only time I've ever heard of this code before was today with a meme about a tea pot
I think that made think about it too
Same, and I didn't understand the teapot one, either.
So, the web works on http (and https). When you ask for some content ("make a request") on the web, the place you asked ("the server") replies with the best content they can find for what you asked, along with a short code as a hint of what the reply contains ("the response"). You may be familiar with the response code 404, which signifies the thing you asked for could not be found, and the actual reply usually contains a cute error message saying the same thing. You can think of the response content as the part of the response meant for humans, and the response code as the part of the response meant for other computers.
Response code 418 is a joke response code put into the standard (it was an RFC document for the 1St of April for some year). It is meant to signify that the server cannot really fulfill your request, because in reality, you aren't talking to a real server, but a teapot some nerd managed to hook up to the internet (this was before the era of IoT was upon us and every appliance wanted to be smart and connect to the internet.)
So, it can be viewed as the "sir this is a Wendy's" joke counterpart of the http response codes.
Me: "Hey computer, go find me the post with most activity in the past 6 hours." Server response: "error 418. Sir, this is a teapot...."
I guess I am one of the lucky 10k today.
Right here with you, pretty hilarious return code.
this was before the era of IoT
TBF remotely-controlled coffeemakers were a dream of nerds since the eighties if not earlier. I remember reading a fascinated account of some dude who kludged up such remote control in the office kitchen, such that the couple minutes it took him to walk there from his office was the exact time it took the coffee to brew. Of course, this is an everyday thing now.
Oh it goes deeper. I encourage you to read about the Trojan Room Coffee Pot at University of Cambridge. This was, essentially, the invention of the webcam.
Also, the Linux Coffee Howto
I think I've read about these too — there's been a period when I consumed old lore aplenty. Like reading all or at least most of the Jargon File (I've had it in the non-linear format of being plugged into actual dictionary software).
I should've been more specific. I meant, internet of terrible things.
I'm a big fan of small appliances talking to each other and reporting status and being remote controlled, but not in its current commercial form. And yes, ever since we have had networking, we have had nerds attempting to make small devices talk to each other and do useful things remotely.
I was extremely disappointed that HA proxy won't let you return 418.
Pretty sure that you can use it with a CloudFlare custom error page.
"Sir, this is a Wendy's" is a 418 I'm a Teapot meme for fast food slobs.
Er, wut?
It's an April fool's joke from... 50 ish years ago. Hypertext teapot control protocol. Status code 418 was supposed to be what happens if you try to get it to brew a cup of coffee. It cannot brew coffee, it is a teapot.
"This is a Wendy's" is a response to wildly off-topic remarks, similar in case to 418
You have your sense of time a bit out of whack.
Development of HTTP was initiated in 1989.
Which was clearly like 12 or so years ago, right? .... right? crumbles to dust
That was 100% me transposing the numbers xD I thought it said 1989 for the joke, it was 1998. Also I did the math wrong and said 50 instead of 40, two fuck-ups for the price of one!
