Long-form notes on agentic systems, engineering judgment, astrophotography, hardware, coffee, and the tools that make a life easier to inspect and improve.
I recently subscribed to Devin, an AI programming tool, for $500 per month. It claims to be a versatile intern capable of performing many tasks that traditional AI tools like Cursor and Windsurf cannot handle. After using it for a while, I noticed significant differences between Devin and Cursor in terms of design philosophy and user experience, which I'll summarize in this article.
