Programming skills are necessarily for a game designer?

To the best of my understanding it's beneficial to your abilities as a designer, and also looks good on a resumé, if you understand the basics of coding.
It's easy to come into the gaming scene and tell people what they should be doing in a game without understanding the parameters they work within, so it's good to have a basic understanding of the main parts of the game.

Thanks a lot for all of this, guys! I'm in a similar situation to that of MrbrianM, and all of these resources will be very, very helpful for me.

One thing I've been considering is buying a book that I can carry around with me and read when I'm stuck somewhere and have nothing else to do. To get to and from school, I have to sit around on trains and buses for a long time.
Can anyone recommend any good books for this type of thing, or would I be better off just sticking to online resources?

Really guys, thanks again. This has been great.
