In Elixir, data structures are contracts. By using tagged tuples like `{:ok, value}`, success and failure become explicit data rather than hidden states you might forget to check. Here is why the shape of your data is the feature. grox.io/blog/20-when-t… #ElixirLang

Building a Phoenix app in 30 minutes with AI is impressive, but working code and maintainable code are not the same thing. We looked inside the generated code to see where the shortcuts were taken and how to fix them. #ElixirLang grox.io/blog/19-the-mo…

In Elixir, inner scopes can read outer bindings but can't change them. Once you see that boundary clearly, the common rebinding mistake stops looking like a bug and starts looking like a design. grox.io/blog/18-scope-… #ElixirLang

AI built a full Phoenix LiveView app in 30 minutes, then kept adding “helpful” features nobody asked for. The demo looked perfect. The maintenance story is where the real cost appears. New blog post! grox.io/blog/17-the-il… #ElixirLang

In most languages, = stores a value. In Elixir, = matches a shape. If the structure fits, names bind. If it doesn’t, the match fails — and that failure is the filter. Pattern matching is selection, not assignment. Full post: grox.io/blog/16-patter… #ElixirLang

I am tremendously excited that CodeBeam is in Vancouver this year! This class is the foundation for our beyond-vibing AI course on Grox.io. I can't wait to see what people think.

This Master Class is about structured prompting, architectural patterns, and proper oversight. It's about building production-ready systems with AI, not letting AI generate whatever and hoping it works. You are in charge, not the agent.

I have been sitting on this article for 3+ months to see if it would stand the pace of change in AI and I believe it did. So here it goes! The future of coding agents is vertical integration: tidewave.ai/blog/the-futur…

The problem with AI coding agents isn’t capability. It’s visibility. Without checkpoints, you end up approving changes you haven’t really seen. Ask → Plan → Agent adds explicit decision points before code runs. Stop vibe coding. Start directing. grox.io/blog/15-the-ed…

@IamSandeshSoni Tidewave MCP plus the AGENTS.md "mix phx.new" generates for you!

In Elixir, data shape is a design decision. Atoms signal meaning. Tuples encode fixed structure. Lists imply sequential access. Maps express association by key. The shape you choose affects behavior, readability, and evolution. New post: grox.io/blog/14-data-s… #ElixirLang

Heyo, I built a thing for fun: PR Quiz! It is a MCP App that turns pull request reviews into an interactive learning experience, inside Claude Desktop (and others). Watch the video, links below.

In Elixir, calling a function doesn’t immediately run code. First, the runtime selects a function head by pattern matching on the shape of your data. Only then does the clause execute. That’s why greet(:admin) and greet(:user) are the same function. Full breakdown: grox.io/blog/13-functi… #ElixirLang
