Very useful, thanks bentanweihao 
@bentanweihao thank you!
@bentanweihao this is very nice and certainly a nice complement to the book! Do you have a ETA for the final version of the book?
October! Almost there! 
I know this is an old thread, but I still reference these sheets every now and then and I noticed an error. In the ‘Callback’ block under ‘Synchronous Operation’, the handle_call/3 return value is invalid.
Thanks for putting these together. 
You are right! Will get to it in a bit. 




Did you ever update this cheat sheet?
