Part 2: A comprehensive reference covering every glob pattern from basic wildcards to advanced features like brace expansion and extended globs. Learn the rules that apply everywhere.

Glob patterns are everywhere - .gitignore, shell wildcards, build configs - yet most developers learn them by accident through copy-paste. Here’s why glob deserves explicit teaching.

Part 4: Learn how ZSH completions work under the hood. Build custom completions for your scripts, understand _arguments and completion contexts, and make tab completion actually useful.

A complete overview of Rust testing strategies: unit tests, integration tests, property-based testing, snapshot testing, parameterized tests, and doctests. Learn which testing approach fits your needs.

Three Rust error handling crates that seem to overlap but fill distinct roles. Learn when to use thiserror for typed errors, anyhow for application code, and error-envelope for HTTP boundaries.

The ? operator looks like magic. One character that handles errors, converts types, and returns early. Understand how it actually works under the hood and when to use it.

Needed offline GCP Secret Manager testing for CI/CD pipelines. Existing solutions were either too heavy or incomplete. Built a standalone gRPC emulator that works with the official Go SDK–zero credentials, zero network calls, 100% local.

Everyone uses Powerlevel10k, but do you understand how that fancy prompt actually works? Learn the ZSH primitives behind instant git status, command timing, and async rendering.

Protocol Buffers (protobuf) is Google’s binary serialization format - smaller, faster, and type-safe compared to JSON. Learn what protobuf is, how it works, and when to use it for APIs and microservices.

Started with Bitwarden-only shell scripts. Needed to support 1Password and pass without breaking anything. Built a shell abstraction layer, then ported it to Go. Same interface, three backends, zero breaking changes.
