Assembled cognoscenti I was watching a documentary on the fabulous gee-wiz world of autonomous cars; which is apparently going to lead to super safe car journeys and a revival of automotive manufacturing in places where it has been abandoned ! "Autonomous cars are coming, and it's time for everyone to just accept it." http://www.roadandtrack.com/car-culture/features/a26991/autonomous-cars-the-... But then I remembered mention of automotive OS hackers taking over control of a vehicle, http://www.wired.com/2015/07/hackers-remotely-kill-jeep-highway/ and all of a sudden the night-mare possibility of 'driving' in a vehicle which has the reliability of a Windows PC, augmented with the capacity to crash and kill me; struck full force [apologies to those who retain the original usage of hacking as 'DIY OS and IT enthusiasts'; this is obviously the more modern denigrating usage of 'OS cracker vandal etc'] In http://www.wired.com/2012/12/automotive-os-war/ there is mention of QNX, Windows and Linux. I guess the question which is bothering me; is in these automotive and perhaps (aeronautical ?); applications of OS's where bugs, hacks and security holes really are' life and death' issues; are the security holes which have been found; just programmer carelessness or reflective of the seemingly never ending generation and discovery of bugs and security glitches ? Will we finish up with something like Qubes; http://www.linux-magazine.com/Online/Features/Qubes-OS where Debian VM's are the security weak point ? regards Rohan McLeod
