Whether you’re trying to build a software factory or already running one, you’ve probably heard some...

Set up your development tools in Docker Sandboxes, control network access, and reuse your environment with snapshots and Dockerfile-based templates.

We've gotten really good at building AI Agents. With so many frameworks, and higher level...

Over a hundred runs of a controlled experiment on my own repository: what makes ADRs actually reach a coding agent, what parts of a record matter, and the one sentence that changed the result.

A few years ago (three years at most), one of the biggest challenges QA Engineers faced was: how do...

Last week I asked a teammate, "Is the build green?" He replied with four paragraphs. There was...

Static scanners read npm packages without running them, so they miss the postinstall that only fires at install time. I gave my AI agent one tool that runs the install in a disposable AWS CodeBuild sandbox and catches the curl | bash from …

Claude Code, Codex and Antigravity each ship on their own channel and on their own schedule. A small set of Bash scripts brings all of them to the latest release with one command, reports versions without touching anything, and keeps going…

Flash plays a rhythm-runner level from raw pixels. So I hid speedrun-style skips in it: a pad fling over a spike pit, a ghost ship, spike surfing. Nothing on screen gives them away. Here's how I built them, and what they're worth.

An agent crashes after email 40 of 100. Our first fix for it was taken apart in dozens of comments. Here are the two mistakes they exposed, the five decisions we made, and the first tasks open to contributors.

I tried to find out which of my comments mattered. The answer was not the one I built for. A few...

One of our clients, an industrial equipment distributor with about $85 million in revenue, kept its...
