hypervisor now don't rely on collections but only on the SQLite database for saving what post it has computed. It saves each post after each post, and marks it as shared before sharing it so if something bad happens, then it won't crash on it again. RAM usage has been improved too. After 8hrs running, it used more than 1GB. Now it barely uses more than 50MB.
Added a try catch for null pointer exception so it won't crash if a part of the JSON is missing. It'll just continue and don't compute this reddit post.
everything is working fine and can be used in testing environnement as it hasn't been tested long enough for being safely deployed in production environnement
