I highly recommend that any "hacker" have a moderate familiarity with at least 2 assembly languages or similar instruction sets. Not necessarily enough to be an assembly programmer, but enough to understand what kind of operations happen at that level and how various implementations differ. I've found such knowledge to be very helpful at times when working in C/C++, JVM and ActionScript projects.
