- Observable.map [reactivex.io]
- Observable.flatmap [reactivex.io]
- map vs flatmap (alchemist and cheese shredding analogy [reddit])
- Observable.zip [reactivex.io]
- Observable.combineLatest [reactivex.io]
- Observable. switchMap [reactivex.io]
- Observable.distinctUntilChanged [reactivex.io]
- Observable.lift explanation [reactivex.io]
- Observable.compose
- Don’t break the chain (using compose) [blog.danlew.net]
- Observable.filter [reactivex.io]
- Observable.take [reactivex.io]

- Common Issue with Retrolambda (NoClassDefFoundError) [github.com]
- uses js instead of java, but concepts are the same and this is the best explanation I’ve found so far.
- Ring buffer size: System.setProperty("rx.ring-buffer.size", "128");
- Issue with changing buffer ring size [github.com]
- It’s 16 on Android, down from 1024 originally. :P So it’s actually 64x smaller.
