    204: OTP 27 and Blend for Lib Maintainers

    204: OTP 27 and Blend for Lib Maintainers

    In this episode of the Thinking Elixir podcast, we sit down with Marcelo Dominguez, the driver behind the new "Blend" library, which assists Elixir library developers in testing their projects against multiple versions of dependencies. Marcelo explains the genesis of Blend and the inspiration from the Rubygem "appraisal." He discusses how Blend tackles the common headache of dependency version clashes and integrates smoothly with CI systems to isolate and report specific compatibility issues. We learn how it works under-the-hood and helps library maintainers more easily keep their promises of supporting a library used in diverse environments. We cover the motivations, complexities, and real-world applications of Blend and more!

New Elixirian

Recently started learning functional programming and subsequently elixir. I found this podcast and love the blend of general tech discussion and more focused elixir talking points. Favorite episode so far is “End of local host development.”

Thinking About Thinking Elixir

This may be the best podcast about Elixir. The episodes are released at a regular cadence, the audio and conversion quality is great, and the topics don’t feel repetitive. The weekly news summaries are super handy.

And, the intro music can’t be beat. 😁

Excited for more!
