Why I Recommend to Avoid Using the go-kit Library

There is a trending 'microservice' library called go-kit. I've been using the go-kit library for a while now. The library provide a lot of convenience integrations that you might need in your service: with service discovery with Consul, distributed tracing with Zipkin, for example, and nice logic utilities such as round robin client side load balancing, and circuit breaking. It is also providing a way to implement communication layer, with support of RPC and REST.

Go vs. Scala (Akka) Concurrency

A comparison from 2 weeks using Go.

Actors vs. Functions

Akka's central principle is that there you have an ActorSystem which runs Actors. An Actor is defined as a class and it has a method to receive messages.

Devise / Warden Tagged logging

I wrote a middleware (actually two, but they do the same with different implementations) that logs information about signed in scopes in a Rails + Devise application. The solution works with multiple logins (like having a person logged both as an Admin and a User). I tested against Rails 4 and Devise HEAD, but it should work fine in any Rails 3 application.

This solution doesn't use the log_tags configuration option since it isn't very helpful when you need to retrieve information stored in cookies/session. That information isn't 'ready' when the Rails::Rack::Logger is executed, since it happens way down in the middleware chain.

Add one of the following implementations to your application load path and use the following configuration to add the middleware to your application stack:

# application.rb
