Swap Size In my previous post I suggested making swap space […] I recently had a chance to briefly play with the new Samsung Galaxy Camera [1]. The Galaxy Camera is an Android device with a 4.8″ display (the same size as the Samsung Galaxy S3) that has a fairly capable camera (IE nothing like a typical phone camera). It runs Android 4.1 (Jelly Bean) and the […] My new Samsung Galaxy S3 phone takes a micro-SIM (see the Wikipedia page about Subscriber Identity Modules for details [1]). All my other mobile devices take a mini-SIM so I can’t just put the SIM from my old phone in my new phone. I’ve just made my second application to Virgin Mobile for a new […] A member of SAGE-AU [1] found two ATM skimmers [2] and gave me permission to publish his description and analysis of the situation.
