LocalCluster v2.0: Cleaner API and improved OTP support
LocalCluster is a small library to help in testing distributed states in Elixir with temporary clusters.
The latest release (v2.0.0) now ships with a much cleaner API, while supporting all of the same use cases as v1.x and improving OTP compatibility.
The v2.0.0 will delegate to specific modules based on your active OTP version, so while LocalCluster is still compatible with Elixir v1.7+, developers using the latest versions will make use of more recent tools (such as :peer).
Check it out, I welcome any feedback :)

How to implement primitive "Did you mean ...?" functionality in Elixir?
Enhancing user experience involves providing helpful feedback when users make mistakes. One effective way to do this is by suggesting corrections for incorrect input, often phrased as “Did you mean …?” This guide demonstrates how to implement such functionality in Elixir using the Jaro Distance string similarity metric.
