RX Video Review Part 2


My previous post makes it seem like there’s no good RX videos.  Actually the RX in Depth videos are excellent for what they cover.  On the rxwiki, these are the only videos they link to specifically.  They mostly talk about how you can combine Observables and show “marble diagrams” (such as the above picture) that make it all very quickly comprehensible.

The drag drop demo is good to show the power and WOW Factor of RX.

So there are some good videos, but maybe what I’m looking for is some detail on the classes and methods.  There’s no videos about helpful classes such as Subject or ReplaySubject and no discussion of the methods available other than the combinators.  I’m sure there’s a wealth of classes and methods available in RX.  I’m going to have to look further to find the documentation I prefer.

The “Hands On Lab” is 42 pages – I may look into that.

RX – Don’t Start Here

I’ve been working on a project that uses RX for several months now and its a really incredible technology, but annoyingly undocumented.  I finally decided I’d watch the videos and stop complaining that there’s no book or guide that will take me from intro through all the functionality with lots of properties and methods explained.image

Then again, the videos aren’t exactly informative.  Wes and Eric have made a total fetish out of describing IObservable in terms of the dual of IEnumberable and you’ll see that in a bunch of videos.  I’d prefer a more solution oriented approach explaining what you can do and common scenarios and then when you understand things, it might be interesting to get that aha when you see that this is the dual of IEnumerable, but introducing it with a deep dive into its duality, while it must be a geek coup, does nothing to help my understanding.  Then again, these guys are much smarter than I am, so who am I to argue.

This video is similarly abstruse.  This “in depth” video is only one minute and forty seven seconds long.  I get the impression I’m missing an hour of what I’m looking for.

This blog post, in addition to having some cool simple examples, led me in the right direction.  This video seems to be what I’m looking for, some actual code with explanations.  Too bad my media player only has a 4” screen.  Can’t wait till the new one comes.

Looks like I’m right on time, the hands on lab was just published the other day.
