Dude, the word "Gruber" is a hyperlink in the article. Just click on it.
EDIT: No, seriously. If someone has no idea who Gruber is and they click through to his site, tell me where on the screen they would see information that answers the implicit question "Who is Gruber and why would him finding out about this problem aid its resolution".
I retract my snark, or at least a little bit of it.
