The Ray Tracer Challenge: "discuss" link is broken, possibly also "report erratum" (All pages)
In the book, at the bottom right, there are the “discuss” and “report erratum” links, pointing to:
- discuss: http://forums.pragprog.com/forums/jbtracer
- report erratum: http://pragprog.com/titles/jbtracer/errata/add
The “discuss” link is broken; it’s redirected to https://pragprog.com
The “report erratum” link is not strictly broken, but not exact either - it points to the book page (https://pragprog.com/titles/jbtracer/the-ray-tracer-challenge), but the errata page, which is mentioned in such page, is actually https://devtalk.com/books/the-ray-tracer-challenge.

I don’t know if this helps you, but we moved all the book forums and errata here to Devtalk last year. So all reviews, comments, questions, and errata can be found here now, and you can see them all on the book’s tag page: #book-the-ray-tracer-challenge.
