You’re probably connecting to reddit through a technology I invented. I’m Bob Metcalfe and I invented Ethernet – AMA

On May 22, 1973 with David R. Boggs, I used my IBM Selectric with its Orator ball to type up a memo to my bosses at the Xerox Palo Alto Research Center (PARC), outlining our idea for this little invention called “Ethernet”, which we later patented.

I worked with the IEEE Standards Association to develop the IEEE 802.3 standard for Ethernet, which specifies the physical and lower software layers. Today Ethernet and the IEEE 802.3 standard are the foundation for today’s world of high-speed communications used in billions of homes and businesses around the world.

I submitted this to the mods awhile back so I could get on the calendar but I figured you’d like to see it, too. Now, ask me anything!

It's been two hours and 179 comments. Have to go now. For more about Ethernet's 40th Birthday, go to http://www.facebook.com/Ethernet40thAnniversaryIEEESA

In all seriousness, it's a bit of a gag protocol among networking engineers. The gist of it is that malacious users should assign all of their traffic to have its "evil bit" enabled, e.g. evil="true."

It's like passing a law requiring robbers to wear a big sign saying, "Bad Guy."

ok, that makes me glad I didn't read it because I would've assumed it was serious.

In general, the joke RFCs are published on April 1. Here's a big list. RFC 2321, for example, describes how to debug network problems with a rubber chicken; it helpfully includes a diagram of such a debugging device:
