The other has been #nethui,
I find it amazing when I cannot attend a conference that I can still enjoy it online, twitter is a great conference tool.
I had this one tweet come through
We need a hacker culture in schools. You don't get that with iPads. Need open technologies, circuit boards, Raspberry Pis
I totally agree with this, and continue to fight technicians in schools to open up the networks and computer to allow students to get a touch of such an exiting part of computing.
One resource I find interesting is hacker high school, hackerhighschool.org this is a excellent example of how hacking could be taught to schools students.
the other is the raspeberry pi project. Years ago we talked about people bringing in devices to plug into networks that were small and could sniff a lot of data from the network. This has all of that, an ethernet port, small profile and a power cable that looks like it is for a mobile phone. Thinking about that, you could probably get a raspberry pi to fit into a old mobile phone.
