I've seen a load of Java/VB/perl programmers who have no idea what
effects their high-level code has on the low-level stuff; resulting
- needless disk accesses
- needless network accesses
- data structures that are extremely cache-unfriendly
- use of heap instead of stack for performance-critical frequent
allocation and deallocation (although in those interpreted languages
this is pretty much unavoidable as far as I know)
- absolutely no comprehension of why those are bad things
A bit of low-level experience makes these issues clear.
As Kenn said, 'It is the "first principles" that everything derives from.
It is a common language that everyone can revert to. It is what is
underneath all these nice, friendly layers of abstraction.'
