Presentation: Local First – How To Build Software Which Still Works After the Acquihire

Alex Good discusses the fragility of modern cloud-dependent apps and shares a roadmap for "local-first" software. By leveraging a Git-like DAG structure and Automerge, he explains how to move from brittle client-server models to resilient systems where data lives on-device. He explores technical implementation, rich-text merging, and how this infrastructure simplifies engineering workflows.

Article: Stateful Continuation for AI Agents: Why Transport Layers Now Matter

Agent workflows make transport a first-order concern. Multi-turn, tool-heavy loops amplify overhead that is negligible in single-turn LLM use. Stateful continuation cuts overhead dramatically. Caching context server-side can reduce client-sent data by 80%+ and improve execution time by 15–29% .

Presentation: State of Play: AI Coding Assistants

Birgitta Böckeler discusses the rapid evolution of AI agents, moving beyond "vibe coding" to sophisticated context engineering. She explains how architectural constraints and "harness engineering" create the safety nets required for autonomous code generation. She shares vital insights for leaders on balancing speed with maintainability, security risks, and the cost of AI autonomy.

Presentation: When Every Bit Counts: How Valkey Rebuilt Its Hashtable for Modern Hardware

Madelyn Olson discusses the evolution of Valkey's data structures, moving away from "textbook" pointer-chasing HashMaps to more cache-aware designs. She explains the implementation of "Swedish" tables to maximize memory density. She shares insights on systems intuition, memory prefetching, and the rigorous testing needed for mission-critical caches.
