You mean you didn't find SAM helpful or Mobx?

@jannesiera re 'Signals and Systems' - the concepts appear to be straightforward but some of the notation is over my head ~ I do like the appearance of "nextState" functions in Chapter 3, however

@gunar I did not find that Mobx brings a lot of value to link the different part of SAM (state derivation, action and mutation).
On an other I find it useful for generating the "view data" (in the State function) as an observable store to use with React.

@dfkaye_twitter the notation takes a bit to get used to, but since it's an introductory course used at Berkley they actually take the time to explain everything. I could follow quite well until the chapter on linear systems, because there they assume pre-existing knowledge of matrices etc which I'm not very familiar with.
IMHO if you are interested in thinking fundamentally about your 'programming model' then this book provides a great baseline to start understanding functional programming, pure and impure, side effects, events, streams, composition, concurrency, types, etc etc and frame those things in a meaningful way (especially because it provides a mathematical way of thinking about systems which can be computers or otherwise, as is demonstrated by the fact that the course is given to both computer scientists and engineers).

@jannesiera I see, that's pretty cool! thanks for sharing :+1:
I did Signals and Systems in university, but I don't remember any of it :grimacing:

@foxdonut any way you can track down your course material? Do you think with the experience you have now you would see that material in a new light?

@jannesiera I went to university from 1992 to 1996, so, tracking down the material might be difficult!
but.. this book cover does look familiar... https://www.amazon.com/dp/0138097313
