Manage the Context Window

Daniel Griesser's custom sub-agent workflow for context management was ahead of its time — what he hand-rolled is now being shipped as first-class tooling. The core insight still stands: context is precious, and managing it intentionally is everything.

Deep Modules and AI-Ready Codebases

Matt Pocock argues your codebase is the biggest influence on AI output, not your prompt. His solution is deep modules from John Ousterhout's A Philosophy of Software Design. It maps perfectly to how CQRS already works — each service boundary is a deep module with commands and queries as its interface.

Mole — macOS Disk Space Cleaner

Mole is a macOS command-line tool that bundles system cleaning, smart app uninstalling, and build artifact removal into one binary. Ran it while fighting a disk space crunch and recovered over 20GB in minutes.

Subagents and the Smart Zone

Matt Pocock explains why subagents are the dominant pattern for coding agents, keeping work in the first 40-50% of the context window where models perform best.

Raspberry Pi with a Purpose

Got a new Raspberry Pi, but this time it's not for tinkering—it's for an actual project. First time installing a heat sink that won't be used to play Counter Strike.

Discovered EaseMaster – A Playground for Custom Easing

Found this fantastic tool for exploring easing functions. It's opened up a whole playground for experimenting with custom timing curves to match the vibe and feeling of different animations.

Design Patterns for Humans

Solid resource for understanding design patterns with good explanations and examples.

Compiled Conversations #17: Event Sourcing

Shawn McCool discusses Event Sourcing as a modelling technique—how it differs from Event Streaming, why aggregates work better as short-lived lifecycles, and how CQRS pairs naturally with it. Touches on DDD as a pursuit of domain understanding.
