The conference was also founded in part to fill the vacuum caused by the sudden ending of the Detroit, Michigan Rubi-Con event, though it has now achieved its own personality and prominence.
Notacon 3, took place April 7–9, 2006,[4] with talks such as "Make Your Own Linux", "Blended Threat Management", "How to Survive a Federal Investigation", "The Great Failure of Wikipedia", "Kryptos and the Da Vinci Code", "HajjiNets: Running an ISP in a War Zone" and "Your Moment of Audio Zen: A History of Podcasts".
A few of the talks were in direct association with the computer club Infonomicon, as several of their more high profile members spoke at the con, including droops, kn1ghtl0rd, p0trill023, irongeek, and ponyboy.
Other notable speakers in 2006 included Jason Scott, Elonka Dunin, Drew Curtis, and Eric Meyer [5] Notacon 4, April 27–29, 2007, worked as an incubator for Blockparty, the largest running North American demoparty.
