Pattern Matching in Elixir
In this introduction to pattern matching we walk through a few examples of how it’s used in Elixir.

Sage is an dependency-free implementation of Sagas pattern in pure Elixir. It is go to way when you dealing with distributed transactions, especially with an error recovery/cleanup. Sage guarantees that either all the transactions in a saga are successfully completed or compensating transactions are run to amend a partial execution.
It’s like Ecto.Multi but across business logic and third-party APIs.

Looking for feedback about stdlib Logger improvements!
Posted a new proposal to the mailing list, please take the time to read over it and let me know your thoughts! As new features can only be added if they’re supported on the mailing list, it’s vital that thoughts make it there :)

Three tutorials covering deploying Phoenix apps to Google Cloud
For those interested in deploying an Elixir/Phoenix app to Google Cloud, I’ve posted three getting-started tutorials on Google’s community site:
- Deploying to App Engine for spinning up an app with a minimum of work
- Deploying to Kubernetes Engine to get on board with containers
- Deploying to Compute Engine if you want complete control over your cloud resources
#TIL: mix hex.docs open ecto
I love that mix hex.docs open ecto opens Ecto’s docs in my Browser. I’d love to have something like mix hex.readme open plug to open README.md files just as easy.
