Diffs, Trees, and VS Code 2.0
Scott and Wes sit down with Alex Sexton and Amadeus De Marzi from Pierre Computer to dig into the gnarly performance challenges behind building blazing-fast code review tools, covering virtualization, progressive rendering, and why GitHub's UI feels so sluggish. They also chat about how major AI coding tools like Claude, Codex, and Cursor are adopting Pierre's diffs library, plus the role of web components, benchmarking, and what it takes to build "VS Code 2.0."
