Starting from a Unbuntu server with Nginx installed and set up with Let’s Encrypt HTTPS, we install Postgres, Elixir and Phoenix and then make an automated deployment system using Distillery and Edeliver.

After setting everything up, deployment can be done entirely from your local machine and upgrades take only only a single command.

Bitcoin BIP-39 style wallet seed mnemonics sounds like a mouthful, but the underlying ideas are simple. The process of generating these mnemonics gives us an excellent opportunity to flex our Elixir muscles.

I think an idiomatic Elixir web framework should be based on message passing. This post explains how to do that and why I have built an alternative to the Cowboy/Plug/Phoenix web stack.

Server Sent Events with Elixir/Plug

Server-Sent Events (SSE) is a lightweight and standardized protocol for pushing notifications from an HTTP server to a client. In contrast to WebSocket, which offers bi-directional communication, SSE only allows for one-way communication from the server to the client. If that’s all you need, SSE has the advantages to be much simpler, to rely on HTTP 1.1 only and to offer retry semantics on broken connections by the browser.
