Telemetry UI
A lot of popular Elixir packages (eg. Phoenix, Oban, Absinthe, Tesla) come with a built-in integration of Erlang’s telemetry system. But for it to actually be useful to you, you have to do something with telemetry events 🙂
Telemetry UI is a package that stores events in PostgreSQL and displays them inside your Phoenix application. The data stays on the same infrastructure and you can control how you display it.

ThinkingElixir 116: Remote Development and Elixir
Episode 116 of Thinking Elixir. In episode 110, we talked about, and rejected, the argument for the “End of Localhost Development”. Carter Bryden joins us to share a perspective from the other side, one in favor of remote development. We learn about the benefits to contractors, PR reviews, giving demos, and how containerizing our development environment even improves local development. We learn about the tools, services, and techniques that make it possible. An interesting look into a different way of developing our favorite language!
