Let me just trace where this is coming from for you: while laughing again at an XKCD comic, I was led to Google the name "Eric S. Raymond" (the references to Richard Stallman and Linus Torvalds I got, but I didn't know much about ESR), which then led me to his home page and then to the Jargon file (a classic collection of terms and information on hacker culture) and to the Meaning of Hack section.

This story is probably well-known to many seasoned hackers, but it gave me a good laugh:

1990's addition to the hallowed tradition of April Fool RFCs was RFC 1149, A Standard for the Transmission of IP Datagrams on Avian Carriers. This sketched a method for transmitting IP packets via carrier pigeons.

Eleven years later, on 28 April 2001, the Bergen Linux User's Group successfully demonstrated CPIP (Carrier Pigeon IP) between two Linux machines running on opposite sides of a small mountain in Bergen, Norway. Their network stack used printers to hex-dump packets onto paper, pigeons to transport the paper, and OCR software to read the dumps at the other end and feed them to the receiving machine's network layer.

Here is the actual log of the ping command they successfully executed. Note the exceptional packet times.

A web page documenting the event, with pictures, is at http://www.blug.linux.no/rfc1149/. In the finest Internet tradition, all software involved was open-source; the custom parts are available for download from the site.

While all acknowledged the magnitude of this achievement, some debate ensued over whether BLUG's implementation was properly conformant to the RFC. It seems they had not used the duct tape specified in 1149 to attach messages to pigeon legs, but instead employed other methods less objectionable to the pigeons. The debate was properly resolved when it was pointed out that the duct-tape specification was not prefixed by a MUST, and was thus a recommendation rather than a requirement.

Welcome to my little corner of the web. I'm currently majoring in computer science and minoring in music at Utah State University while working for the Programming and Design Team in USU's Department of Information Technology. Most of the time work seems to be full-time and school is the side job, but reality sometimes reminds me that this is not exactly the case. Don't get me wrong though—school is important and has taught me much, but working on the PAD team has taught me more about computers and even about life than I have ever learned in a classroom. It's exciting to be integrated into a team that deals with projects from every facet of a University and hence from innumerable facets of technology.

Hopefully, I'll share a piece of this here that you may stumble across while perusing the interwebs and it might serve a good purpose for you. That's the ideal situation though—there's much potential for it turning into me rambling about topics that may only interest a few people. But, to those few, welcome!
