Java: Randomly sort values in a array (the generic way) in single pass

Few years back (yes, about 4 years back), I wrote an article about randomly sort query results in MySQL. The main problem in randomly sort query results is that when you have a very large data in your database and the statement to sort the result may change the data execution plan causing DMBS does not choose the right plan. Therefore, sometime it is more wise to sort it in your own program instead of too depending on DBMS's decision which may affect the overall performance of a program.

Regular Expression Test Tool

When writing a software, you may need to use regular expression to filter some string values or to validate some input strings. It is quite troublesome to test the correctness of the regular expression pattern that you have designed. You will need to compile you source code, execute the compiled binary, perform some steps until to the point that make use of the regular expression. It takes a lot of time to do the trial and error especially if you are not very familiar with regular expression.
