A quiet revolution is happening in how developers work. Instead of focusing on one task at a time—the traditional “flow state” approach—engineers are increasingly kicking off multiple AI agents simultaneously, managing several workstreams in parallel....
$20,000 in API fees. Two weeks. Zero orchestration. Sixteen Claude Opus 4.6 instances working in parallel just produced a 100,000-line C compiler that can build a bootable Linux kernel. This is either a glimpse of...
One year ago, AI coding assistants could write maybe a quarter of a developer’s code. Today? The latest models can generate nine-tenths of it. This isn’t hype—it’s the lived experience of developers working at the...
In 2021, the IDE had won. Copilot made auto-complete so powerful that fighting with environment integration seemed worth it. Four years later, David Crawshaw—founder at Tailscale and Sketch—is back on Vi. Vi is turning 50...
What happens when you let 16 Claude instances collaborate on building a C compiler that can compile the Linux kernel? Anthropic’s Nicholas Carlini just showed us—and the results challenge everything we thought we knew about...
Building AI agents that interact with Slack? You’ve probably discovered the hard way that the Slack API returns massive JSON blobs that burn through your context window. Agent-Slack takes a different approach: ship a CLI...
What happens when you give an AI agent root access to run arbitrary code? If you’re lucky, it installs packages and writes files. If you’re unlucky, your API keys end up somewhere they shouldn’t be....
After 25 years of evolution, the Integrated Development Environment may have just met its successor. And it happened faster than anyone expected. The Core Insight David Crawshaw, who has been documenting his journey with AI...
Stop fighting the chatbot. Start engineering the harness. If you’ve been circling AI coding tools with suspicion—or worse, trying them and bouncing off—you’re not alone. The hype machine says these tools will 10x your productivity....
Understanding the evolving security landscape of AI agent ecosystems The Attack Surface Problem AI agents with system access represent a fundamentally new security paradigm. Unlike traditional software that does exactly what code tells it to...
