Embedded

David Such joins us to discuss his new book, Embedded AI: Intelligence at the Deep Edge. We explore the boundary between classical signal processing, heuristics, and edge machine learning; IMU processing and sensor fusion; and how to determine what sort of ML fits on your processor. David also shares his experiences writing for No Starch Press and why future robotic architectures need a digital cerebellum for low-level reflexes.
David Such is an electrical engineer based in Sydney. He is the director of Reefwing Software.

Adam Smith from UC Santa Cruz joins us to discuss local Small Language Models (SLMs) and building open, autonomous tools. We explore his BayLeaf AI counterplatform, transagency (the "me-and-the-car" concept of human-agent collaboration), context distillation, and running models locally without relying on data-harvesting corporate clouds. 
Adam also shares practical strategies for working with coding agents, including why plain-text AGENTS.md files outperform model weight fine-tuning for long-term knowledge retention. He also describes how he uses open-source tools like OpenWebUI, OpenCode and OpenChamber to integrate small and local LLM integration into development environments and web chats.

Open-Source Agent Harnesses & Wrappers:
OpenCode – Open-source command-line coding agent harness with VS Code integration (comparable to Claude Code)

OpenChamber – Graphical desktop wrapper for OpenCode with VS Code support (comparable to Claude Cowork)

OpenWeb UI – Self-hosted web interface and desktop app for local and remote LLM models

OpenRouter – Token broker/middleman routing requests across competitive LLM inference providers

r/LocalLlama – Community subreddit for local LLMs, open weights, and hardware advice

AGENTS.md Convention & Agent Skills Standard – Open standards for persistent context management

Context Distillation Paper (arXiv)

Adam's Guide to Building Transagent Capabilities:
Scope by Project Roots: Harnesses like OpenCode and OpenChamber use project root folders to establish clear, safe boundaries for agent execution.

Store Context in Plain Text: Keep global and project preferences in simple .md files (like AGENTS.md or GLOSSARY.md). Plain text files make your accumulated knowledge portable across different model front-ends and harnesses.

Handle Errors by Rewinding: When your LLM or agent makes a mistake, don't yell at it or try to correct it inline—go back in time to before the error and alter your prompt or context to lead it away from the mistake.

Refactor Preferences into Skills: As your AGENTS.md context grows, ask the agent to factor recurring preferences out into modular skill files (.agentskills).

Teach Transagency: Distinguish between standalone agent capabilities (autonomous work) and transagent capabilities (how the agent works with you).

Build Local Tools: Ask the agent to build desktop helpers (QuickLook triggers, push notifications, or fuzzy glossary lookup) to keep a shared orientation.

Elecia: "Complete one project or start a dozen?"
Adam: "Tens of thousands, and start hundreds more within the starting of the other projects recursively forever."
Transcript

Aaed Musa joins us to talk about building robot dogs, custom actuators, and his YouTube channel. He shares how he moved from 3D-printing servo robots in his parents' garage to designing capstan drives, and how he uses reinforcement learning to train quadrupedal walking gaits. We also talk about his senior design project (CARA 2.0), his Spider-Man web-shooter build, lessons in storytelling and video editing, and why he's starting a company to bring friendly, expressive quadrupeds into the home. 
Aaed Musa is a mechanical engineering graduate from Purdue University, a hardware creator on YouTube, and co-founder of the robotics startup Mecha.

Author Susan Lammers joins the show to discuss the 40th anniversary edition of her classic book, Programmers at Work. We discuss what it was like to interview young and pioneering software developers like Toru Iwatani, C. Wayne Ratliff, and Michael Hawley and how the personal computer revolution was built by individuals seeking freedom from corporate mainframes. 
Susan also shares her experiences as Editor-in-Chief at Microsoft Press, leading Microsoft's early interactive CD-ROM division, founding Headbone Interactive in the 1990s, and why she's bringing retro games like Elroy Goes Bugzerk back to Steam today.

Kevin Santo Cappuccio, founder of Architeuthis Flux, joins the show to discuss creating Jumperless, an open-source breadboard that replaces physical jumper wires with software-controlled analog crossbar switches. We explore the need for 445 RGB LEDs on a breadboard, using MicroPython to create scriptable circuits, some of the lessons that can be implemented with the Jumperless, and how it might be used to create new instruments. Kevin also shares the story behind his upcoming Barnacle Board.
