Azure is not yet as popular cloud provider, so the community attention and support is a bit scarce. I wrote how to take advantage of shared access signature (SAS) to implement the typical use case of pre-signing blobs from the Azure object storage.

Toxiproxy is a proxy to simulate network and system conditions. The Elixir API aims to make it simple to write tests that ensure your application behaves appropriately under harsh conditions.

So any time recently that I’ve gone looking for a good overview of supervision trees in Elixir I haven’t found what I want. So I tried to build an example and write a bit about it. Hope it helps people.

In episode 18 of Thinking Elixir, we talk with German Velasco about his free book Test-Driven Development with Phoenix. He shares his experiences of learning TDD at ThoughtBot, his writing process, tips and more. On TDD, we talk about the benefits we see, the process of “Red Green Refactor”, tools and even when we don’t do it. Some great insights!

Recently I set out to configure a service of ours to run behind a reverse proxy with TLS termination.

With Phoenix being the great framework it is, I assumed this would be a breeze. But it turned out that reality had different plans for me.

In this post I’ll tell you a story on all the different bits of documentation I rummaged through, the things I learned from reading the source code of Plug.SSL, the solution I arrived at, and the proposal I submitted to plug.
