Eye in the Sky DVD

Eye In The Sky | | Instant Video

Eye in the Sky is a military-legal drama, starring Helen Mirren as a Colonel at the centre of a Unmanned Aerial Vehicle (UAV) attack on terrorists in Nairobi, Kenya. Although much of the film focuses on the ethical questions surrounding premeditated strikes and collateral damage, there is a strong undercurrent of ideas relating to drone technology and the opportunities is creates. The film also features cutting edge technology such as miniature drones (including a hummingbird and a tiny beetle), which do not exist at the moment but have certainly been mooted. These inclusions makes Eye in the Sky a useful discussion starter for ITGS lessons.

Internet trends

State of the Internet: Internet visualisations

State of the Internet is an excellent page from Akamai features interactive charts to help students visualise Internet trends. Students can view a global map of Internet speeds (which holds a few surprises) and customize the graphs to show data and changes from which countries and time periods they want. The page also contains information about threats and security trends.

This is a great way of examining potential digital divides. A good ITGS lesson idea might be to have students discuss which areas of the world might have the fastest and slowest (or non-existent) Internet access, justify their assertions, and then use this tool to check their accuracy.

Your phone company is watching

Your phone company is watching

Malte Spitz discusses the collection and retention of mobile phone data. The talk links to the databases and the Politics and Government area of the ITGS syllabus and features some great visualisations that show how large amounts of data can be combined to build up patterns about people's lives. Where do people live? Where do they sleep? Are they having an affair? Are they 'likely' to commit a crime? All of these and more can be predicted from captured call data. So many ITGS social and ethical issues are raised.

All your devices can be hacked

All Your Devices Can Be Hacked

All Your Devices can be Hacked discusses the increased security threats as much and more devices feature Internet connectivity - including implanted medical devices, car networks, police radios, and voting machines. The very interesting - and worrying - aspect of this video is that it is not mere scaremongering - all of the attacks described, including disabling a pacemaker and taking over control of a car, have all been successfully executed as proofs of concepts. This makes great discussion material for ITGS students in several different strands of the ITGS triangle.

Examples of FOSS in Use

ITGS students sometimes mistakenly believe FOSS is 'trial' or 'simple' software, or that it lacks features compared to commercial software. The examples below highlight where FOSS in used in the 'real world' and where the advantages and challenges are found, and should help ITGS students understand that very large organisations do make extensive use of free and open source software.

Energy 2D is an interactive heat transfer model. Students can create structures made from different materials and test their thermal characteristics. There are versions for Windows, Mac OS, and Linux, so it should be accessible to all students.
