Signed vs. unsigned data types isn't an artifact of assembly language. It's more so one of digital data representation. I think that knowledge is just as useful to a C programmer as a Ruby programmer. Fire up irb and type 0.1 + 0.2, for instance. You covered what I would have said about the register keyword, but you're right, it's essentially impossible to understand that language "feature" without having a basic understanding of the CPU.
Indeed. My main point was that programming C requires more knowledge about the "layers" underneath its execution than higher level languages such as Ruby.
