Return to the blog ...

It's been an age since I have had the time to blog and this site had fallen by the wayside.  However, I find myself looking for a place to gather thoughts, share ideas and activities, so restarting the blog seems like a good idea.  The name 'Academic Marginalia' is inspired by those thoughts and ideas that one jots down about in the margins when reading something really stimulating.  The idea here is to reflect on my experiences as an academic, both in terms of teaching and research but also on wider issues that affect higher education and scientific enquiry.

Not sure how regularly I will get the chance to update, but will do my best to make regular (albeit sometimes brief!) postings.

Cloud Wedge - geek of the week

CloudWedge: 'Geek of the Week' My colleague Yijun Yu recently wrote a opinion piece for The Conversation about how cloud computing could have made a difference to the search for Malayian Airlines MH370.  Essentially the question he poses is: why, in the age of global internet connectivity (including now onboard planes!), do we depend on the onboard flight data recorder for information about what happens on a plane? Of course there are numerous challenges with this - not least the cost of bandwidth for all the flight data (including cockpit audio) to be uploaded in real time and the security of the data.  Yijun's article addresses some aspects of the latter, and the former is not an insurmountable problem.  For example it should be possible to upload basic flight telemetry (e.g., GPS location, air speed, engine statistics and fuel data) without requiring significant bandwidth.  Indeed aero engine manufacturers such as Rolls-Royce deployed engine monitoring systems

Priming Code Club

Code Club Assembly Presentation from akbandara As part of my work with STEMnet, I recently signed up as a CodeClub volunteer at St. Bernadette's Catholic Primary School in Milton Keynes.  Working with Kate Clarke, the ICT leader at the school, I am going to be leading an after-school club that will introduce kids in Year 5 and Year 6 to the exciting world of programming.  CodeClub is a nationwide, volunteer driven, grass-roots movement to get kids learning about the fun that can be had programming computers, rather than simply using them. In order to give the kids some idea about what they might be letting themselves in for, last week I delivered the short presentation (embedded above) at the school.  I started out by getting the kids to identify different computers, and think about what a computer really does, i.e. follows a set of instructions to complete a task.  We then played with a neat little iPad game called 'Kodable' which allows the player to progr

Are we losing the Internet Security battle?

Image
I was recently invited by Heimdal Security to take part in an expert roundup, with the theme of "Is Internet Security a Losing Battle?".   The main thrust of my answer was to question our use of analogies of conflict in the context of Internet Security or cyber security.  As I said in my response: "... in this context the metaphors of conflict, such as ‘war’ and ‘battle’ are unhelpful because they suggest that internet security is the responsibility of the technologists who act our defensive force against attackers.   Instead, as has been argued by technology activists like Cory Doctorow  and others we might have more success by thinking of cyber security using the analogy of public health and communicable diseases.   By using this analogy, we make cyber security issues more relevant to people and spur them to gain a better understanding that, like diseases, any of us can be afflicted by a cyber security attack.  We can also adopt an analogous approach for han
