Specs Over Vibes: Consistent AI Results ft. Mark Freeman

There’s so much going on in the AI space, and how to work with AI agents is changing every day. Everyone is overwhelmed and almost numb from so many possibilities, yet you need to find a way to work with AI, not to get left behind, right? You might use AI agents all day long, parallelizing them with AI orchestrators like Agent Teams, Gastown, tmux, git worktree, and AI-based IDEs, but in the end, you just coordinated an AI. You still have to learn what it created, understand it, check for…

GLM-5.1: Towards Long-Horizon Tasks

GLM-5.1: Towards Long-Horizon Tasks

GLM-5.1: Towards Long-Horizon Tasks Chinese AI lab Z.ai's latest model is a giant 754B parameter 1.51TB (on Hugging Face) MIT-licensed monster - the same size as their previous GLM-5 release, and sharing the same paper. It's available via OpenRouter so I asked it to draw me a pelican: llm install llm-openrouter llm -m openrouter/z-ai/glm-5.1 'Generate an SVG of a pelican on a bicycle' And something new happened... unprompted, the model decided to give me an HTML page that included both the SVG…

Anthropic's Project Glasswing - restricting Claude Mythos to security researchers - sounds necessary to me

Anthropic's Project Glasswing - restricting Claude Mythos to security researchers - sounds necessary to me

Anthropic didn't release their latest model, Claude Mythos (system card PDF), today. They have instead made it available to a very restricted set of preview partners under their newly announced Project Glasswing. The model is a general purpose model, similar to Claude Opus 4.6, but Anthropic claim that its cyber-security research abilities are strong enough that they need to give the software industry as a whole time to prepare. Mythos Preview has already found thousands of high-severity…

SQLite WAL Mode Across Docker Containers Sharing a Volume

SQLite WAL Mode Across Docker Containers Sharing a Volume

Research: SQLite WAL Mode Across Docker Containers Sharing a Volume Inspired by this conversation on Hacker News about whether two SQLite processes in separate Docker containers that share the same volume might run into problems due to WAL shared memory. The answer is that everything works fine - Docker containers on the same host and filesystem share the same shared memory in a way that allows WAL to collaborate as it should. Tags: docker, sqlite

Building an Agent-Friendly, Local-First Analytics Stack with MotherDuck and Rill

Building an Agent-Friendly, Local-First Analytics Stack with MotherDuck and Rill

Imagine going from a 100-million-row dataset to an interactive analytics app with just a few prompts. What used to take hours or days can now be done in minutes by combining local-first databases and BI tools with an agentic coding workflow. When Rill bet on YAML dashboards and CLI-first workflows in 2022, they weren’t thinking about AI agents. Neither was MotherDuck when they built serverless DuckDB around the thesis that most data fits on a laptop. But it turns out, what is developer-friendly…
