My second day in Umea – a tiny little university town in the north of Sweden, where I am attending a workshop on Social Media Cultures at the HumLab. The program for the workshop looks quite hectic, peppered by series of 10 minute presentations to be followed by short discussions. Tomorrow [Monday] I am presenting on sociable objects, to be followed by a presentation on online knowledge creation on Tuesday.

The key theme I want to drive in the first presentation is that objects are starting to acquire the power to produce a semantically rich dynamic flow of data, which makes them (or rather their information output) hard to distinguish from humans. The implications are that you could friend and engage someone’s twitter feed in the same way that you could friend and engage a car’s info feed (in fact, the Toyota Friend program is going exactly in that direction).

In my second presentation I am concentrating on the importance of continuous, dynamic engagement with and reflection on content in an online environment. The idea is that knowledge creation occurs in a constructivist scaffolding-like framework where students continuously engage with content on a variety of levels, while simultaneously reflecting on that process.

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.

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.
