Frameworks

• Twitter Bootstrap (for css, design)
• Backbone for clear application MVC structure
  • Mustache.js for javascript template rendering/ Backbone.View dynamic updating.
• Socket.io for data transfer
• jQuery for DOM manipulations

Cloud IDE Server side

• Source files are stored in CouchDB (Git Commits too).
  • Develop git->couchdb storage layer
• Some project configuration files are stored in CouchDB (information that is not relational, does not require aggregation)
• User information/ statistics stored in PostgreSQL
• Source files/ git tarballs precached in Redis
• Tornado serves as a "proxy" layer between CouchDB/Postgre/Redis and Client.
• Tornado passes control commands from client to Compilation Unit logging communication and sending it to client.
• Long-running/ time consuming tasks Tornado offloads to celeryd. (make celery async result passing compatible with Tornado's IOLoop (epoll/select compatible solution)).

TODO

• For smart/simplistic DB Connection pooling: Async Semaphores (i.e. DeferredSemaphore in Twisted)
• Git->CouchDB storage Layer
• Celery working in Tornado IOLoop (non blocking AsyncResult (although, name is async, on KeyValueStorage (i.e. Redis, Memcache) it is blocking or long pooling). Further more, all communications with Message storage/ backend should go through IOLoop without blocking.

Editor

• CodeMirror - http://codemirror.net/

"Gets more attentions from large companies: i.e. Adobe is using it for developing Brackets (HTML5 + CSS editor). New IDE LightTable (http://www.kickstarter.com/projects/306316578/light-table). Weights much less then Ace, simpler code, easier to extend." 

"I will try to add abstraction layer, to remove complete dependency on CodeMirror"

Javascript/ Dom manipulation

• jQuery

Design/ UI

• Twitter Bootstrap

"I will be using bootstraps' css styles and layouts, for faster UI development, and jQuery for all javascript related operations."
