From a consumer perspective, what's wrong with c9.io being purchased by Amazon? Shouldn't that mean more stability and an acceptance by enterprise of cloud coding?
Linux is the kernel. The semantics of this can be argued all day, but the kernel is not the operating system. It is simply the tiny piece of software that allows processes to run and manages memory and hardware access. The operating system is the whole collection of software that allows the User to manage their system. It necessarily includes the kernel, but it is much more than just that one component.
I don't consider ChromeOS to be a Linux desktop any more than I consider my Android smartphone to be a Linux desktop, or an iPhone to be a BSD system. They happen to share a kernel, but that's really where the similarities end as an end user.
The title seems misleading. People with marijuana in their bloodstream != stoned drivers. Marijuana use is detectable for a long time past the point of impairment and the data only reflects that they HAVE used marijuana vs being stoned at the point of driving.
Maybe instead of breathalysers and drug detection kits we should have standardised attention/reaction tests to determine if someone is safe to drive (you could probably even run them on a tablet). This would also weed out (pun intended) tired drivers.
