Whenbot - a personal open source ifttt.com clone. (check out http://ifttt.com) Wiki page with more info: https://github.com/ottawaruby/whenbot/wiki/_pages simple luuunchbot app: https://github.com/redronin/luuunchbot The idea: A simple web service that runs on Heroku that lets you listen on certain triggers and perform actions to other web services based on that. For example: Whenever I post an Instagram photo, create a Tumblr blog post. It would be personal - in that it's meant for each person who wants to run it to clone the repo, and host it on their own Heroku instance. Heroku provides enough free addons and services that you can get it up and running and functional without paying for anything (or at the most, a few bucks a month). Basic premise is that you have: Triggers - things that you listen on (new instagram post, a tweet, a new email, a new RSS feed entry, etc.). This can be a scheduled polling to a certain API endpoint (heroku offers regular schedule tasks every 10 minutes), or webhook endpoints. Parsers - things that take the output from a trigger, and massages/normalizes the data into a known format that can be consumed by... Publishers - things that you publish to (send a tweet, create a Tumblr post, send an email, etc.) The basic engine could be a very simple app, and the Triggers, Parsers, and Publishers can be individual modules/classes. This would allow people to work on various triggers, publishers, etc. on their own while still contributing to the project as a whole. There'd also be UI work to create the actions, configure services, etc. Most triggers and publishers would just be using various API wrappers for web services like Flickr, Tumblr, Posterous, etc. This would be a great way for people to get exposed to APIs from various web services. Some are complicated, some are pretty simple, so there'd be lots to choose from. I created a simple Instagram => Tumblr / Posterous app for http://luuunch.com which I could show. It uses a ridiculously simple Tumblr publisher, Posterous publisher and an Instagram webhook trigger. An immediate use case for something like this would be to create an instagram / flickr / etc. feed to add to the OttawaRuby website.
