If you want to learn a new programming language, its possible to get a small taste by visiting one of these websites before you start creating a new development environment.
As the year winds down, I find its a good time to sneak in some research, experiment with new concepts, or even start learning a new language before everything picks back up in the new year.
If you do not have a target language in mind, you can get an introductory sample in your browser before you go off and fetch development kits and associated utilities.Ruby
The first browser-based tutorial to hit prominence was TryRuby. It's still a great tutorial, and anything that has those talking foxes is OK by me. This tutorial sets the pattern that is the basis for most of the other tutorials that follow in this list.Clojure
Interested in a Lisp dialect or typing parentheses? If so, then Try Clojure could be your thing.Python
There's an extensive Python tutorial over at the IronPython website --- unfortunately, it is not as accessible as the others in the list, and it requires the installation of Silverlight.Haskell
If I've missed out an online tutorial that started you on a new language, make sure you leave its URL in the comments.
