It would certainly be fun to write a smartphone application. (So either learn Objective-C and iOS, or Java and Android). But I wouldn't call that "modern programming". I'd like to suggest learning lisp, and do some AI programming (cf. AIMA, PAIP, ML, etc), but then those all come from the era of punch cards and pre object oriented concepts (even if Common Lisp is the first and till now the best standardized OO language). So what good "modern programming" has to give us? Perhaps Haskell. Yes, all there is in Haskell was already in Backer's 1972 paper. But it's a little more recent than the 1959's Lisp. Some days, you really feel trapped inside the Matrix, release 6.0...
