Maybe there's so much complexity in the software stack that we can't start CS majors starting from the hardware level any more, but I can't help thinking we've lost something as a result. These days, there are Java programmers who get that "deer in headlights" look when confronted with terms such as "cache line miss".
Forget that, most of these folks can't reason about a program that doesn't have automatic garbage collection. Even if they have direct experience with C or similar, I have asked recent grads how they imagine reference counting or malloc/free works, and they very often start pulling out GC-influenced magical thinking about "the system" reclaiming things under the covers.
lol, I see what you mean there. Now as long as the person you're talking to has a true engineering mind he/she will be happy to learn about the subject. But there's unfortunately also those that start looking you with eyes begging you to go stop the hardware mumbojumbo talk and go back to oftware only. I don't really consider them true engineers.
The name of the course is "Computation Structures", or, as MIT students would know it (since nearly everything at MIT is numbered, including buildings and departments), 6.004:
