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

Alex Good — Wed, 08 Apr 2026 10:37:00 GMT

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

Anirudh Mendiratta — Wed, 08 Apr 2026 09:00:00 GMT

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% .

Anthropic Accidentally Exposes Claude Code Source via npm Source Map File

Steef-Jan Wiggers — Tue, 07 Apr 2026 08:00:00 GMT

Anthropic's Claude Code CLI had its full TypeScript source exposed after a source map file was accidentally included in version 2.1.88 of its npm package. The 512,000-line codebase was archived to GitHub within hours. Anthropic called it a packaging error caused by human error. The leak revealed unreleased features, internal model codenames, and multi-agent orchestration architecture.

Article: A Better Alternative to Reducing CI Regression Test Suite Sizes

James Bornefelt Westfall — Mon, 06 Apr 2026 11:00:00 GMT

How can you focus in a sea of results from a large regression test suite? This article describes a stochastic approach that relies on some degree of redundancy in your CI regression test set. This approach does not guarantee you will catch every bug every time, but it gives you your best bet of not missing the subtle signatures of all the bugs uncovered by your CI regression test suite runs.
