Discourse in Altervista, si può?

Ciao ragazzi,

mi chiedevo, se in qualche modo, è possibile installare la seguente applicazione http://www.discourse.org/. Dalle FAQ si legge questo:

Discourse is a JavaScript application that runs in your web browser, using the Ember.js JavaScript framework.

The server side of Discourse is written in Ruby on Rails with a Postgres database, and Redis server cache. You can deploy Discourse on a virtualized cloud server (Amazon EC2, Rackspace, Azure) or on cloud hosting (Heroku, Engine Yard, Appfog, etc) wherever Ruby on Rails is supported. The minimum version requirements are:

Postgres 9.1
Redis 2.6
Ruby 1.9.3
We also recommend a minimum 1 Gb RAM to host Discourse, though it may work with slightly less.

Queste caratteristiche, Altervista, le ha? Grazie!

Non non le ha. Su Altervista non c'è Ruby e non c'è Postgres.
