Ansible delegation madness: delegate_to and variable substitution

This is going to be a short piece but I really want to share this because 1) I have to talk! It cost me several hours today to get a grip on this and 2) I couldn’t find any explanation of this Ansible behaviour on Stack Overflow or anywhere else (I actually posted this on SO to make sure it’s now there). By the way, I was reminded today that it can save you several hours of bug tracking, experimenting and general hair-tearing if you just know to ask....

What I've read - Week 42/13

Actually this is my reading list from the last several weeks. I haven’t had the time to write these down, though, since we were preparing for ICNP 2013. Since me and my teammate are developing an overlay P2P network for Browsers we are especially interested in implementation patterns for such overlays. One very well-known paper is the one from Dabek et al. titled “Towards a Common API for Structured Peer-to-Peer Overlays”....
