To my surprise, it seems fairly active: https://github.com/nhibernate/nhibernate-core I stopped working on nhibernate around 2010-2011, when i started masters. I did only keep in touch with one friend - i am not very sociable person. So I guess short answer is, i am not sure to be honest. Back in 2008ish, I was thinking it was going to die because Entity framework provided a great support for linq, and it had a great hype. A bunch of enterprises moved away from NHibernate (we also had a lot of legacy from XML configuration - a bunch of internal data structures were referencing xml), so it was clunky. Fabio, Oren (Ayende) did a bunch of improvements, I worked a bunch of shortening initialization times and so on. I think Ayende did a very good job with Linq initially, but there were plenty of edge cases that i remember having to fix :) It w

as my first opensource project as a core member (second and last was castle project) - so it has a very special place for me :)

For .NET / SQL Server people, check out GuidCombs if you want better Primary Key performance. These are a great way of making GUIDs sequential for database use, giving indexing performance close to ints on SQL Server. I imagine this approach could also work on Postgres and other dbs that have made GUID/UUIDs a first class data type. You'd just have to understand how that database applies its indexing algorithm. Description of the GuidComb approach here: http://www.informit.com/articles/article.asp?p=25862 GuidComb implementation in C# (from NHibernate core) here: https://github.com/nhibernate/nhibernate-core/blob/master/sr...
