Verified publisherWhat a VS Code verified publisher badge means, compared with Open VSX →
Provide everyone with their own virtual duck in VS Code. Introduce students to rubber duck debugging, a technique that involves talking to a rubber duck (or any inanimate, or even animate object) about a bug in their code. This virtual duck does not have, by design, any form of AI functionality.
