I agree, which is why I started my own series, as lmm mentioned, with showing simple ways of (ab)using gcc to figure out how to do simple/primitive code-generation, and built up from that, instead of building down from lexing/parsing.
Lexing/parsing is important of course, but it's been done to death, and for most of the simple types of languages people tend to use for teaching, it's a simple problem.
Code generation, on the other hand, is still pretty poorly covered, in my opinion, and something people tend to struggle with a lot more, even if you resort to tools like LLVM (and that's fine if that's what you want, but I'd argue you should try a lower level approach at least once to understand some of the challenges)
