Make your multiple type view adapter with annotations!

Gist for Making a Multiple View Types Adapter With Annotations

Pretty easy to use.

1. Create your delegate adapters, implementing DelegateAdapter, and with the annotation DelegateAdapterType. e.g:

@DelegateAdapterType(itemType = 0)

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
