On my radar: RethinkDB + React.js + Rails
RethinkDB is the open-source database for the realtime web and it can push JSON to your app in realtime.

Over the last few weeks I’ve been working on a Sunspot_Neo4j gem, but found it difficult to test that it was working across versions of Neo4j. I ended up creating the Neo4j_Test_Server to do just that without having to setup a bunch of dedicated Neo4j instances. Here’s how.
