"WAMP" is an acronym formed from the initials of the operating system (Windows) and the package's principal components: Apache, MySQL and PHP (or Perl or Python).
Personally I use XAMPP Lite, but thats because I haven't tried anything else. I've just been looking as to how to install SQLBuddy on it, and can't find out.
I've heard about the Uniform Server as well as WAMP5.
What WAMP do you use and why?
