What Are RFCs? The Forgotten Blueprints of the Internet

These are the RFCs we know, and many others we don’t. The ones “lost” to obscurity generally deserve the fate but I enjoy reading them for the historical context. Fascinating stuff.
ErikCorry•1h ago
Forgotten? No mention of why we should think they are forgotten outside the headline.

Outside of my friend group, no one uses XMPP, the internet standard for chat, they only know about walled gardens and custom protocols by VC startups now :(
SunlitCat•31m ago
Since when became XMPP "the internet standard for chat"? What about IRC[0]? :(

[0]: RFCs 1459, 2810 - 2813, 7194.

lou1306•29m ago
Come on, of course there will be some protocols that are more obscure than others, but the overall concept of RFCs is far from "forgotten".

Besides, a lot of these walled chat gardens roll their own XMPP/Jabber thingy behind the scenes.

MYEUHD•9m ago
Whatsapp, Zoom and Kik Messenger use XMPP under the hood.

Just because it's not well-known doesn't mean it's not widely used

Nowadays, my friend, people just copy, paste, or vibecode everything. If you (or anyone) think they’re not forgotten, you’re one of the few who still read and understand the RFCs. Said that in the post too.
alterom•23m ago
Yeah, as if reading and understanding RFCs was the pastime of the commoner in Ye Olde Dayse.

Or as if the vibe-coder of today would've totally™ definitely© be the type of person to peruse the RFCs.

It's like saying the the proof of, say, Seifert-van Kampen theorem is "forgotten" because nowadays, my friend, people ask ChatGPT to write out solutions to their math homework.

I don’t know what niche you inhabit, but anecdotally the overwhelming majority of engineers I know have consulted an RFC. RFCs are an active component in the Internet; you need to at least reference them (if not fully read them) to understand how various parts of the Internet interoperate.

(It seems extremely unlikely that the average non-junior engineer hasn’t opened up RFC 3339 or one of the HTTP caching RFCs, just for example.)

The fact that you are able to send this message over the internet is proof that a quite large population of people are still reading and still understand internet standards.
Anon1096•8m ago
The people building the infrastructure powering the internet at cloudflare, major cloud providers, isps, etc are all regularly reading and referencing RFCs (from experience). People who aren't reading them now weren't reading them in the past either, we don't need some RFC moral panic.

"With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea."

Reminds me of a Russian joke:

Can a hedgehog fly? Yes, if you kick it.

"It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead."

"with sufficient thrust, anything can fly -- it's the landing that can get messy"
dcminter•55m ago
Not forgotten, but this article did not mention my favourite and the most moving RFC: 2468

https://datatracker.ietf.org/doc/html/rfc2468

There's quiet genius in that choice of number by the way. 2, 4, 6, 8, who do we appreciate?

Wow, never heard of this one before. Thanks for sharing!

Aren’t all PEPs, TC39s, and BIPs forms of RFCs?
woodruffw•21m ago
They’re all forms of requests for comment, but people also typically mean RFC to mean IETF RFCs.
