Thinking Elixir Podcast ThinkingElixir.com

In this landmark 200th episode of the Thinking Elixir podcast, we dive into the revolutionary world of LiveView Native with Brian Cardarella and Carson Katri. Discover how this emerging technology is expanding Elixir's reach onto mobile devices and beyond, shaking up traditional development with server-side state management and opening a new frontier for native applications. Our experts share insights on its performance, live reload features, and strategic advantages that promise to speed up prototyping and cut down on dev time. Plus, hear about our latest news on EEF voting, new testing libraries for Phoenix, the future of the Elixir Protobuf library with a call for new maintainers, and Livebook's integrations for data sources. And if that wasn't enough, we cover additional tech stories, including the shutdown of the Women Who Code foundation, a study linking mentally stimulating work to a reduced risk of dementia, and more!

In this episode, we talk about the eagerly awaited Elixir 1.17.0-dev changelog, the exciting ExDoc v0.32 release, and the slightly amusing declaration of Cloudflare playing the websocket hero – about 9 years after Phoenix neatly demoed 2 million concurrent connections to the world. We also explore potential performance improvements with Ecto's support for unlogged tables and how PragProg's new Elixir book is shaping up as a must-read for DevOps enthusiasts. But that's not all, we also touch on the launch of a constraint solver in Elixir, a nifty Livebook visualization tip, and more! Plus, don't miss out as Mark, Tyler, and David also share insights into their current projects, ranging from tackling Elixir mock libraries to the latest in the tech conference scene and educational initiatives in the Erlang ecosystem.

Fly.io: Fly.io is a great place to deploy your next Phoenix applicatio

In this compelling episode, we sit down with Ben Reinhart who shares his journey of transitioning from the JavaScript ecosystem, specifically migrating off of Next.js and Vercel, to Elixir and Phoenix, with Fly.io as the new host. Ben discusses his frustrations with the complexity and performance issues he faced, and how the switch to Elixir helped streamline operations and improve the efficiency of his AI-focused product at Axflow. He delves into his strategic choice for leveraging the operational simplicity and real-time features of Phoenix, while also acknowledging trade-offs such as rebuilding front-end components. Join us to explore Ben's story, learn about the features of Elixir that helped him, and discover how the move has influenced Axflow's path towards finding product-market fit, and more!
