Online Course: Introduction to Node.js

Finally have a look at the node.js, very impressive. the behavior driven testing with mocha and should.js is beautiful. the integration work with socket.io is actually some feature i have been looking for. and the process fork/spawn/exec is an elegant solution for start another process within the node.js

Online Course: Introduction to OpenStack

Very nice course for the introduction of openstack, although a bit general and no enough details on specific projects such as keystone, glance, nova, cinder, heat, ceilometer, etc (understandable as it is an introductory course and openstack is quite huge).
