The venerable Dr. Dobbs Journal is still pretty good. It covers multiple platforms, and mixes some fairly hard-core technical articles with lighter fare (interviews with notables, a "Developer Diaries" column that profiles regular-Joe (and Jane) developers from a range of fields). If you are employed and have authority to spend some non-trivial amount of money on tools (or are willing to claim that you do), you can probably get them to send it to you for free.

For the Microsoft world, MSDN Magazine is very useful. Some of their columns are excellent, particularly Jeff Richter's Concurrent Affairs.
