I read down to the http://netflix.github.io/ link, tried it, the carousel advanced to fast for my slow eyes I guess, I manually selected the radio button, started reading and ... the next slide came up before I finished. Then I got into a war with the carousel timer. Frustrating on that but the page looks nice once you hit the carousel radio buttons enough to read it.
You can prevent it from advancing by keeping you cursor in the carousel body. That doesn't really make up for the fact that a carousel is a poor UX choice, but it's a handy trick for carousels that advance too fast and it works on most implementations.
Edit: Now that I think about it, using the cursor hover to prevent the carousel from advancing seems like an anti-pattern. If most users are like me, they will move their cursor out of the way of the carousel to prevent obscuring the content. I have seen users who like to trace and/or select the current text they are reading, so maybe it works better for them.
