Dan Abramov's "React for Two Computers" explores using React to build a collaborative interface between two physically separate computers. He demonstrates a simplified approach involving manual synchronization of component state between browsers using server-sent events (SSE). By sending state updates over a server as they happen, both clients maintain a consistent view. This method, while not scalable for numerous clients, offers a practical illustration of the core principles behind real-time collaboration and serves as a conceptual foundation for understanding more complex solutions involving Conflict-free Replicated Data Types (CRDTs) or operational transforms. The post focuses on pedagogical clarity, prioritizing simplicity over production-ready implementation.

AI-powered code review tools often focus on surface-level issues like style and minor bugs, missing the bigger picture of code quality, maintainability, and design. While these tools can automate some aspects of the review process, they fail to address the core human element: understanding intent, context, and long-term implications. The real problem isn't the lack of automated checks, but the cumbersome and inefficient interfaces we use for code review. Improving the human-centric aspects of code review, such as communication, collaboration, and knowledge sharing, would yield greater benefits than simply adding more AI-powered linting. The article advocates for better tools that facilitate these human interactions rather than focusing solely on automated code analysis.
