IPoAC: Transfering Data With Pigeons

December 12th, 2009

The quality of internet services in South Africa suffer from poor bandwidth limitations. Frustrated with this problem, internet company Unlimited IT performed a stunt that showed it could transfer data much faster than Telcom’s (the contries leading ADSL provider) service.

Unlimited IT’s carrier pigeon backed data transfer reached speeds of 1 gigabyte per hour while transferring to a location 100km away. That’s a speed of about 270KB/second.

The idea to use homing pigeons to transfer information is not new. Ancient Egyptians were the first known civilization to be using carrier pigeons 3000 years go. The Roman’s used carrier pigeons to aid them in war over 2000 years ago. The use of carrier pigeons became most prominently known when their use became an important part of World War I and II.

On April fools day 1990, D. Waitzman of Cambridge Massachusetts described an internet protocol using carrier pigeons to transfer data in RFC 1149. This protocol later became known as IP over Avian Carriers (IPoAC).  On April fools 1999, Waitzman improved the protocol in RFC 2549. In 2001 however, a Linux User Group took the idea a little too seriously and implemented the protocol using pigeons to transfer data over a distance of 5km, before Unlimited IT of South Africa implemented this protocol as a marketing stunt.

Scabbler – The Game

December 2nd, 2009

Scabbler is a new way to play Scrabble. It’s just like scrabble with the following new rules.

Placing words:
1. Words made in Scabbler must be non-scrabble-words. I.e. they can not appear in the Scrabble dictionary.
2. Words made in Scabbler must be well formed, that is, they must sound like a real English word.

Scoring points:
1. Same rules as scrabble
2. with the additional rule that non-scrabble words that anagram to scrabble words receive a multiplier of 1+the number of anagrams found at the time of placing a word.

Scabbing points:
1. A player can scab the points away from another player by contesting the non-scrabble-wordness of another players word by looking it up in the dictionary. If it turns out to be a real word, the contester receives the value of that word in points. If the word turns out to be a non-scrabble-word, then the contester loses half the value of that word in points.

That’s it. Happy gaming!
