• Analog: Science Fiction and Fact
  A paid print and digital magazine I used to subscribe to. I'm only not currently subscribed because I had fallen literal years behind and couldn't keep up. Includes not only fiction but science and futurism essays.

• Clarkesworld
  A paid digital and print magazine, and free podcast. I would listen to this podcast more but they offer no description and I can't commit to an hour or story time just based on a title.

• Asimov’s Science Fiction
  A paid digital and print magazine. Tends to have bigger names than Analog and Clarkesworld.

My favorite is always Analog in print form.

That's how we would have to do non-copyable classes before C++11. Older code bases are still filled with unimplemented copy constructors and assignment operators with comments. If you were extra thorough they'd also be private. PC Lint hated both of those tactics.
