Raspberry Jam – Bastille Day

Posted by Jon Crowcroft

The glorious quatorze juillet in the Computer lab, we had >250 people in attendance at the Raspberry Jam, and TeachMeet, to bring toegether raspberry owners, wannabes, hackers and observers, and then to discuss specifics (e.g. lesson plans) for using Rasberry Pis and related tech for teaching the Computing at School curriculum.


For me, highlights included

1. Demo of RiscOS on Pi

2. School governer showing how to democratize ICT/CS in the school by embedding it in everything (using free and/or opensource s/w only, and no geek/operator/ICT technicians at all)


3. A teaching who created over a dozen Digital Leaders to teach computing out of her own 12 year old pupils - these kids to stand up classes and tutorials for parents - just awesome.


4. two talks on literally hundreds of projects out there to carry out in D&T or other non-directly CS classes


5. How to teach healthcare through computers

6. Plenty of hints on first steps in programming

7. Finally Pi foundation folks showed up with 200 devices for people at the event. Also announced various new things (e.g. camera board should be ready Real Soon Now)...


A lot of fun, I thought. Judge for yourself from the video:

One of Leon's vid of the Zoo talk - excelent!


Social Networks: field advanced by people “not in the field”?

Posted by Daniele Quercia

On Saturday I came back from the annual meeting of the UK Social Networks Association (UKSNA). It was the perfect place to meet old friends and make new ones. The program is here . I presented our work on why Twitter is a social network, and on why people "unfriend" each other on Facebook (the latter was covered by the New Scientist today). Interesting presentations include those on Tom Snijeders' multilevel longitudinal analysis of social networks, Harrigan's work on tie formation on Twitter, Emery's on "shared Leadership", and Marcus's on the connected communities project (those are the only presentations I could listen to - i joined a bit later because of other commitments in nottingham)

I was on a panel chaired by Bernie Hogan. The panel was discussing how network studies in the social sciences could help us to investigate the use of "Social Media". Here Paola summarised her thoughts on what was said, concluding:

"...there is an unmet and unrecognised need for theories. We don't know how social influence works in online networks. How social media help to form social capital, and how comparable this is to the social capital we knew offline. Whether local or global network effects are prevalent. How online/offline multiplexity works."

It's interesting to see that all these topics have been recently covered by people on a hybrid ground - that is,  by people who are at the cross road of sociology, physics, and computer science. Namely, NB Ellison's work on building social capital in Facebook, Sinan Aral's on social influence online, and JP Onnela's on multi-slice networks. Development in the field could go no faster - by those who are not "in the field". Brokerage at work? :)
