I don't know, software is far more dynamic than many other engineering fields. Even a first edition of The Art of Electronics is chick full of useful information, the only truly dated stuff is anything involving microcontrollers (so, software). Even the sections on digital logic ICs are still useful, they still see some use. Software has always had the problem of information being outdated before the books even reach retailers. However, this is one of my big frustrations with SO. There are so, so many c++ questions with accepted answers that are now 'wrong' due to changes in the language. That, and the fanatical insistence to close questions that are opinion based closes off a lot of questions more experienced programmers will have.
