On Ruby

MySQLPlus is a new, non-blocking MySQL driver for Ruby 1.8 and 1.9 (anyone know if it will run on Rubinius?) from eSpace, the folks who created NeverBlock. (They also talk about NeverBlockPG, a postgreSQL driver, but it seems to have been deleted.) To quote eSpace's announcement:

[MySQLPlus does] IO operations concurrently and in a transparent manner, thanks to NeverBlock. An interesting side effect emerged during the development of this driver. We were required to update the current MySQL driver to be able to do async operations. Once those were done, we discovered that the basic foundation for threaded support was there. Hence we went forward and implemented it (with help from Ruby gurus like Aman Gupta and Roger Pack). What we have now is a new general purpose MySQL driver that supports threaded access and async operations. This means that you can send queries to a MySQL server in a concurrent manner from Ruby applications. This is big news for those waiting for Rails thread safety. Finally there is a MySQL driver that can help them achieve that concurrency.

I'd love to see what alternative ORMs like Sequel and DataMapper will do with this kind of library underneath them.
