Great article from @ollie about my long-running quest to find the highest-scoring Boggle board. I love the visuals!

Just published a big update to my "X-Ray Glasses for any types" VS Code extension: marketplace.visualstudio.com/items?itemName… It uses the built-in TypeScript server now, which makes it faster and more likely to work with your project. Give it a try! It found some anys in vscode and tsc itself!

For a weekend project, I wrote a VS Code extension: X-Ray Vision for any types. The scary thing about "any" is that it can appear in surprising place and silently spread. No more! This was frustrating, rewarding, and hopefully useful. Give it a try! marketplace.visualstudio.com/items?itemName…

This is the single passage of Effective TypeScript that I've received the most feedback on. Do you have an intuition for why these relationships hold? The latest blog post walks through how they work, what they mean, and why they're interesting effectivetypescript.com/2024/08/30/key…
