In this episode of the Professor Adolfo Neto Podcast, Adolfo sits down with Peter Ullrich, founder of Indie Courses and a senior Elixir engineer, for an engaging discussion about his unique journey from psychology to software engineering. Peter shares his early passion for building things, which eventually led him to pursue a bachelor’s degree in psychology followed by a master’s degree in software engineering and distributed systems. He recounts how he discovered Elixir during his first job and the pivotal role it played in shaping his career trajectory. Peter also dives into the creation of Indie Courses, a video course platform for indie creators, sharing his motivations behind its inception and the challenges he faced along the way. Throughout the conversation, he emphasizes the importance of continuous learning and staying updated with industry trends, whether through Twitter, blog posts, or books.

Elixir is a great language, but some behavior can be unintuitive, confusing and in the worst case lead to bugs. So, I took a look at 10 Elixir gotchas explaining why they exist and how to avoid them!

May Ash be the hidden champion of low-code tools? 👀

• Reduce boilerplate. Describe and configure most. Let me focus on the most valuable parts
• No lock-in. Provide ways to achieve anything, if not already provided by Ash itself
• Provide ways to extend your resources and code base in general
• Active project development
• Helpful and buzzing community

Episode 200 of Thinking Elixir. 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!

It deprecates two form helpers 😞 but introduces new ones to help us fill forms with labels. 🤩

I know it’s a pain to change this, but I think the changes improve our tests. 👇

vfox (version-fox) is a popular general version management tool write in Go, and the plug-in mechanism uses Lua to achieve extensibility. At present, vfox has supported the management of most mainstream programming language versions, and the ecosystem is quite strong. Here you can see the programming language versions and tools that vfox currently supports and manages -> vfox-Available Plugins.

The Elixir and Erlang communities have long been popular for installing and managing multi-version environments through asdf. asdf is also a general-purpose version management tool, and the ecosystem is so rich.

vfox is very similar to asdf-vm in that it uses .tool-versions file to manage project-level and global version information. This means that if you’ve used asdf before, it won’t be difficult to switch to vfox. Because the core implementations of vfox and vfox are a bit different, vfox executes nearly 5 times faster than ASDF~, and the official documentation also gives benchmark results: version-fox Comparison with asdf-vm

If you’ve been using asdf to manage and maintain multiple versions of Erlang and Elixir, then vfox is also a good choice for you.

This article will show you how to install and manage multiple versions of Erlang and Elixir via vfox.

Episode 199 of Thinking Elixir. 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.

The big wigs want PDFs. and Lots of them. Unfortunately, lots of the good info is behind authentication. How can we render a PDF of a page behind Auth?

What’s the fix? About 10 lines of Elixir!
