Counter-networks [lecture]

Prezi from a lecture on hackers, hacktivism, wikileaks, and a couple of other things. I start with the Enigma cryptanalysis effort (how else?), talk a bit about Rejewski and Turing, and then move on to phone phreaking in the 60s, early hacking crews (LoD, 414s, MoD, cDc), hacker subculture  [l33t sp34k], hacking in popular culture [nmap gets a mention], hacktivist case studies, and a bit on LulzSec and stuxnet.

Bridges made of pebbles [lecture]

Yet another prezi, from a lecture I gave on citizen journalism and new forms of news dissemination. I discuss digital content dynamics [scarcity/abundance, economy of access], the transition from gatekeeping to gatewatching [Axel Bruns],  analyse Slashdot and Reddit, and use Steven Johnson’s metaphor of Twitter story development as a suspension bridge made of pebbles to illustrate the rising value of aggregation.
