The reason I'm listing locations at all is quite simple: software is a global industry, and I want to ensure that the Handbook itself has a regionally-balanced coverage, although owing to the logistics of my research and the reality of the concentration of projects therein, I know I'll end up being somewhat US-centric. Deciding upon a primary location for each system requires some delicacy, because there's a vast difference among the places where a system was conceived, developed, tested, manufactured, and deployed (and each of those activities might entail multiple locations simultaneously). For simplicity, I've decided upon one primary location for each system, representing the center of gravity for where the system was developed.
As of the time of this blog, only about half of systems have been assigned a location, so don't be distressed if your favorite country/state/city is not yet represented. I likely will include at least one project from India (specific suggestions are welcome), but I probably won't find a project from Uzbekistan, Wyoming, or Yemen.
