- Stop Repeating Yourself: How to Architect AI Workflows Like CodeApply DRY Thinking to AI Instructions with Axioms, Roles, and TasksIf you keep retyping the same AI instructions, you do not have a workflow. Learn a practical three-layer structure to keep coding agents consistent.AI Elixir Development Tools Best Practices Workflows
- When the Shape Is the Contract: Tuples, Tagged Tuples, and KeywordsHow Elixir Data Shapes Turn Ambiguous Returns into Explicit ContractsLearn when to use tuples, tagged tuples, and keyword lists in Elixir, and why designing return values as contracts leads to clearer, more maintainable code.Elixir Functional Programming Data Structures Pattern Matching
- The Morning After: What That 30-Minute Phoenix App Actually CostsWhy Working Code and Maintainable Architecture Are Not the Same ThingA fast Phoenix LiveView build can look impressive, but hidden structural debt appears when you inspect what AI generated under speed pressure.AI Elixir Development Tools Best Practices
- Scope (Visibility and Isolation)Why Inner Rebinding Doesn't Change Outer Values in ElixirLearn how Elixir scope boundaries reinforce immutability, prevent hidden state changes, and make code behavior predictable.Elixir Functional Programming Immutability Language Fundamentals
- The Illusion of Speed: When AI Builds a Phoenix App in 30 MinutesWhy Vibe Coding Feels Fast and Becomes a Maintenance TrapA 30‑minute Phoenix LiveView demo looks magical – until you see how the yes loop creates hidden scope and long‑term maintenance cost.AI Elixir Development Tools Best Practices
- Pattern Matching: Matching, Not AssigningWhy Elixir Uses Shape Selection Instead of Variable AssignmentPattern matching in Elixir is about selecting structure, not storing values. Learn destructuring, pinning, and how match failure guides control flow.Elixir Functional Programming Pattern Matching Language Fundamentals
- The Editor Is the AgentWhy Checkpoint-Based AI Workflows Create ControlLearn the Ask → Plan → Agent workflow, a two-level safety net, and context discipline for checkpoint-based AI coding in Elixir.AI Elixir Development Tools Best Practices Workflows
- Learning Elixir? Data Shape Is a Design DecisionChoosing the Right Data Structure for Intent and ClarityIn Elixir, data shape determines how code behaves and reads. Learn when to use atoms, tuples, lists, and maps to make your intent explicit.Elixir Data Structures Design Functional Programming
- Learning Elixir? Function Heads Are Chosen by ShapeWhy Elixir Picks a Clause Before Any Code RunsElixir selects a function head by pattern matching the shape of your arguments, which is why the language feels declarative before you touch OTP.Elixir Pattern Matching Functions Functional Programming
- Stop Prompting. Start Anchoring.Why Decisions Should Live in Code, Not ConversationsThe model didn't forget your architecture—it just never lived anywhere durable. Learn how to anchor decisions in structure instead of prompts.AI Elixir Development Tools Best Practices
- Variables Don't Change, They Get ReboundWhy Elixir Bindings Make Concurrent Code PredictableVariables aren't containers you mutate, they're names that point at values. Learn why this distinction matters more than immutability alone.Elixir Immutability Bindings Concurrency
- Stop Writing Statements, Start Writing ExpressionsWhy Everything in Elixir Returns a Value (and What That Changes)In Elixir, if statements aren't control flow—they're expressions that return values. Learn how this eliminates state management and changes how you read code.Elixir Functional Programming Expressions Design Patterns
- Learning Elixir? Align Your Mental ModelWhy Experienced Developers Find Elixir Harder (and What to Do About It)The syntax is easy. The mental model is hard. Learn the one shift that makes Elixir stop feeling sideways and start feeling natural.Elixir Learning Functional Programming Mental Models
