Literature suggestions for best practices / good coding techniques
<p>I am a mid level developer. Currently I work in C# ASP.NET but I have worked in PHP, classic ASP, and a tiny bit in Java (would like to get more into this in the future). I am looking for a few suggestions on good books to help me continue growing in my coding techniques.</p>

<p>Basically a book with lots of best practices, coding tricks, rarely used but very useful features and operators (e.g. the ?? operator), stuff like that. I am NOT looking for a book to teach me a specific language. I don't particularly care about what language the code samples are in but C or Java would probably be best. The suggestions don't need to be limited to pure code objects either. Books with information about database connection management ect. would be good.</p>

<p>Thanks for your suggestions.</p>
