Scott's in Building 42 today and stopped by the offices of Colin Miller. He runs the .NET Micro Framework, which is a "Tiny CLR" and supporting libraries that run on embedded systems in as little as 32K! (although usually more).
This means that C# developers with little or NO background in electronics can create very sophisticated hardware systems including sensors, servos, whatever! Colin gives me the whole scoop and explains how the whole thing works from Virtual Machine to Firmware to Hardware.
