Some years ago, precisely on July/2008 I created codestacker. I know, there were several options to collect snippets, but I decided to code my own solution. More than that I have planned to develop a Textmate bundle and a Mac OS Widget (who cares?), however I did not code these functions.
In the latest days, I migrated all old data to a new app written in Rails 4.2 and hosted on Heroku. The source code is available in Github.
