The Changelog: Software Development, Open Source

Michael Greenwich, founder and CEO of WorkOS, explains AuthKit and secure CLI authentication in a sponsor segment. He walks through device grant flow and how browser-based logins, SSO, MFA, and passkeys benefit terminal apps. Short, clear explanations highlight integration advantages and real-world developer tooling concerns.

David Carney, Co-founder and Chief Strategy Officer at Tailscale, builds identity-aware networking and TSNet apps and leads the Aperture AI gateway project. He discusses clickless auth with TSIDP, making apps appear as tailnet nodes via TSNet, multi-tailnet isolation for safe workloads, and Aperture for private AI API key control and observability.

Reports of targeted attacks on cloud data centers make for surreal tech geopolitics. Living brain cells were shown running a DOOM demo. New tools include an on-device Mac speech-to-text app and a code scanner that exercises repos to find bugs. Web haptics bring programmable tactile feedback to the browser. New MacBook Pro models just opened for pre-order.

Two long‑time collaborators reflect on a farewell and their decade together. They dive into Ladybird's move from Swift to Rust and how AI sped the porting work. Conversation covers Rust tooling like OXC, the rise of on‑prem HomeLab setups, Tailscale networking, and self‑hosted runners. They also debate how AI agents are reshaping development workflows and the future role of engineers.

Burke Holland, an engineer on GitHub Copilot who experiments with AI coding workflows, talks Opus 4.5, Copilot, and agentic development. He recounts one-shot wins, building small apps with models, and how agents fit into real developer workflows. They debate tool costs, why humans still matter for shipping, and how agents enable rapid prototyping and more builders.

Wes McKinney revisits the classic man-month idea in light of agentic software. A tiny CLI, Peon Ping, brings playful dev notifications. Ladybird's move from Swift to Rust for safety and ecosystem reasons is explored. Cloudflare unveils a compact MCP server and Code Mode to cut tokens. A take on attention economics argues money remains the main moat for creators.

Steve Ruiz, founder of tldraw and builder of a high-performance web canvas and SDK. He talks about turning a free whiteboard into a commercial SDK, pricing and licensing experiments, how AI agents change product and team dynamics, internal tooling as a force multiplier, and embedding spatial AI and agents into canvases for new use cases.

News of a major engineer moving to OpenAI and plans to reshape an open foundation for agent tech. A tiny, Rust-based ZeroClaw aims for zero overhead and tiny hardware. A $5 ESP32-S3 runs a personal AI assistant in pure C. Discussion of Steve Yegge's warning about AI draining builders. A sharp global telnet traffic collapse linked to a recent CVE.

Brett Cannon, a Python core developer who drives packaging and tooling like pyproject and lock files. They chat Star Wars viewing orders and the Han-shot-first controversy. They dig into why Python needed a standard lock format, prebuilt CPython binaries, and new tooling like uv and Astral. They also cover governance, STAR voting, and the emotional costs of stewarding open source.

Paul Dix, co-founder and CTO of InfluxData and time-series systems engineer. He recounts running agentic coding side quests, porting PromQL into Rust and validating it against real tests. He explores verification-first workflows, building bespoke delivery and QA tooling, and where agentic development breaks down and needs manual auditing.
