RefactorMyCode.com and Perl
Its yet another interesting and engrossing site which I stumbled across in the past year, funnily enough after hearing about it from an answer to a Stackoverflow question.
The premise of the site is if you have some working code that you’re not totally happy with then offer it up for code review with the hope someone can help refactor it.
The Perl section could do with some more input and engagement. But don’t just stop there because seeing how snippets of code in other languages are refactored is also a good learning experience.
