Rosetta Code

Rosetta Code is a wiki-based programming chrestomathy website with solutions to various programming problems in many different programming languages. It was created in 2007 by Mike Mol. As of 19 December 2010 (2010 -12-19)^[update] Rosetta Code includes 450 programming tasks, and covers 351 programming languages^[1]. The site's content is licensed under the GNU Free Documentation License 1.2, though some components may be dual-licensed under more permissive terms^[2].

Data and structure

The site is organized as a browseable cross-section of tasks (specific programming problems or considerations) and programming languages. A task's page displays visitor-contributed solutions in various languages, allowing a viewer to compare each language's approach to the task's stated problem. Task pages are included in per-language listings based on the languages of provided solutions; a task with a solution in C will show up in the listing for C. If the same task has a solution in Ruby, the task will appear in Ruby's listing as well.
