...pes of school scholarships. Each scholarship goes through a different review process, represented by a state machine (this is not a state machine question). So there are two state machine classes that differ slightly and subclass a generic StateMachine: class ScholarshipApplication belongs_to :state_machine end class StateMachine end class StateA < StateMachine has_one :application end class StateB < StateMachine has_one :application end The problem is I can get a ScholarshipApplication instance to tell me its StateMachine, but the StateMachine can''t tell me it''s Schola...

Proposal for new APIs to list exports. The general shape of the API can probably best be seen from the examples/list-exports.c example. Rich.

This is a series of patches to libnbd and nbdkit adding AF_VSOCK support. On the host side it allows you to start an nbdkit instance which listens on a virtio-vsock socket: $ ./nbdkit -fv --vsock memory 1G ... nbdkit: debug: bound to vsock 2:10809 On the guest side you can then use libnbd to connect to the server: $ ./run nbdsh -c 'h.connect_vsock(2, 10809)' -c
