  Both books I've read. The latter sits on my bookshelf. It was a gift from my girlfriend. Please don't waste your time trying to implement a compiler. It's a PhD level endeavor that will take years of dedicated 60 hour work weeks.

  You are better off implementing a algebraic calculator using LR Parse. Start with Tom Torf's - Programmers Calculator - PCalc. It's written in C and pretty simple. You can fork it from my GitHub account if you have trouble finding Tom's source archive. Tom (may he rest in peace) also wrote several programming tutorials and contributed to comp.lang.c, alt.lang.c and the comp.lang.c FAQ.

The good thing about this subject is that even not-so-recent material can be just as valuable as things don't really change much in the core concepts around language design.
If you want to learn programming languages, looking for stuff on compiler design is a good place to start. I recommend, Compiler Design in C by Holub (http://www.amazon.com/Compiler-Design-Allen-I-Holub/dp/0133049574/ref=sr_1_1?ie=UTF8&qid=1347051377&sr=8-1&keywords=compiler+design+in+c) You build your own compiler and by extension your own programming language for the compiler.
