If you're an Eclipse or Netbeans user, you'll be very familiar with this topic. These IDEs automatically close braces, parenthesis, quotes, and brackets -- ( {},[],(),"",'' ) -- for you as you type in the code editors.

Microsoft SQL Server, as of version 9.0 (2005), allows you to cheat the max row size limit of 8K. If we have a row of variable length data types (ie. varchar), the total byte count can be more than 8K. SQL Server will magically spill the data over to the next page. Cool right? Well...

Working with dates in Java (though not limited to Java) has always been a nightmare. There are lots of good articles out there in Google Land on the topic, but after some very good questions from my class, I thought I'd add my two-cents and code samples to the mix...
