Doh. I was going to put in some links but forgot.

gamedev is a good place to start.

<www.flipcode.com>, also has some decent articles and tips and tricks.

<www.makegames.com>, although slightly self promotional for 'fastgraph' graphics library which on it's own is also a good graphics library albeit only for windows but the information there is generic enough for starters.

<www.gameprogrammer.com>, is mainly a mailing list for game programming. Not too shabby but hasn't been completely useful yet for me. Another resource couldn't help.
