Developing Meta's Orion AR Glasses

Jinsong Yu shares deep architectural insights into the Orion AR glasses, detailing the use of 11 custom microcontrollers for thermal dissipation, the SLAM/VIO needed for world-locked rendering, and input fusion (EMG, eye/hand tracking). He concludes with critical lessons for technical leaders on setting direction, managing complexity through testing, and strategic hardware-software co-design.

Holistic Engineering: Organic Problem Solving for Complex Evolving Systems

Late projects. Architectures that drift from their original design. Code that mysteriously evolves into something nobody planned. These persistent problems in software development often stem not from technical failures, but from forces we pretend don't exist—reward systems that incentivize the wrong behaviors, organizational structures that ignore domain boundaries, and human dynamics.

AI-Driven Software Delivery: Leveraging Lean, ChOP & LLMs to Create More Effective Learning Experiences at QCon

Wes Reisz discusses an experiment to deliver a QCon certification using a Retrieval-Augmented Generation (RAG) architecture and supervised coding agents (Claude Sonnet/Cursor). He breaks down the 4-week serverless video transcription pipeline, RAG variations (hybrid, graph), and the process of structuring prompts for 95% AI-generated code.

When Reverse Proxies Surprise You: Hard Lessons from Operating at Scale

Operating massive reverse proxy fleets reveals hard lessons: optimizations that work on smaller systems fail at scale; mundane oversights like missing commas cause major outages; and abstractions meant to simplify become hidden fragility points. Success requires profiling on target hardware, relentlessly monitoring boring details, keeping hot paths lean, and trusting instrumentation over theory.
