I watched the video and I know the general principles - hot happens even when nobody is subscribed, cold happens "on demand". Also, Publish() converts cold to hot and Defer() converts hot to cold.

But still, I feel I am missing the details. Here are some questions I'd like to have answered:

Can you give a comprehensive definition for these terms?
Does it ever make sense to call Publish on hot observable or Defer on cold?
Is there differences between hot and cold definitions for IObservable and IEnumerable?
What are the general principles you should take into account when programming for cold or hot?
Any other tips on hot/cold observables?

Looking at the Reactive Extensions for javascript demo on Jeff Van Gogh's blog, I thought I'd give it a try in C#/Winforms, but it doesn't seem to work so well. I just threw this into the constructor of a form (with the Rx framework installed and referenced): Observable.Context = SynchronizationContext… >>> More
