That paper got some wide circulation for some reason, but it was an extremely simple criticism (six or seven equations, no derivations involving anything more substantial than distance = rate x time) by a computer scientist that simply misinterpreted the way the GPS synchronization was used (none of the physics was wrong in the paper, FWIW, the problem was that the author's claims about it having any connection to the OPERA experiment were completely unfounded). IIRC someone from OPERA responded to questions about that paper by saying, basically, that it wasn't even worth debunking because they had real work to do, and publicly disproving every amateur with a theory would suck up all their time.
