how does Phoenix circumvent n+1 bugs?

I do not think that it is phoenix who avoids n+1, but the differences between how one uses ecto vs activerecord.

This is the part I cringed at:
We just write phoenix apps like it’s Rails
Nothing like missing an opportunity to improve the status quo.

We just write phoenix apps like it’s Rails, but now it runs faster and doesn’t have N+1 query bugs
This is a very interesting quote. I think it’s clear that everyone here agrees that it is not the ideal approach to Phoenix. Yet it will be the reality for many Phoenix developers, especially as they first get started with Phoenix (well for the ones that come from Rails). And it is heartening that even with that flawed approach there are many benefits to working with Phoenix, partially because how Phoenix gently (and sometimes not so gently) constrains and guides you to better (IMO) solutions, along with the intrinsic benefits of running on top of BEAM/OTP.
Sometimes this is very explicit such as Ecto vs ActiveRecord and sometimes it is more subtle, for examples plugs and maybe contexts. Overall I am really pleased that Phoenix (and Elixir) is able to remain approachable to those just getting started with functional programming, especially those coming from an OO background. Many other functional languages do not have this, especially languages like Haskell and perhaps even Clojure. The fact that Phoenix/Elixir is approachable is one reason that I’m betting my career (not entire career of course) on it.

Really interested in the [topic] as well. The only technical non-shallow podcast I know of is DevZen http://devzen.ru/ (multitude of programming langs, elixir included, databases, various networking stuff etc). Sorry guys, russian only. I’m yet to find something similar in terms of quality in English.
