Thoughts on systems, engineering, technology, and life.

The Fine Print

My first comic strip, inspired by our growing tendency to trust AI-generated content without questioning the fine print, and by the importance of validating what we present as fact.

  In Memory of Eric Maginniss Eric Maginniss will be deeply missed. What a sharp mind, what a gifted software engineer. In my ~30 years in this field, I’ve had the privilege of working with some incredibly bright individuals, and Eric was absolutely…

A new era of software engineering: long live AI.

  We have entered a new era of software development where natural language, AI, and intuition replace traditional coding. The new programming language? English. The new compiler? Prompts and Large Language Models. The new IDE? Natural language conversation. We’re moving from spec-driven, syntax-first coding to vibe-coding— Where…

Artificial intelligence (AI) is no exception to these principles. In this essay, I will explore the concepts of AI system…

Thoughts on Tesla’s Computer Vision-Only Approach to Navigation
