So what we are saying here is that in the "did a bit of preliminary googling before writing something foolish" department, they did about as well as a HN commenter.
Seriously, the slight difference here makes your comparison less than flattering. This seems like some form of "damning with faint praise".
I stand corrected and I apologize to Dr. Ron. I am still not sure how much Shamir is responsible for the flaws in this research given that he's not the first author.
I'm not sure about this particular paper, but in most theoretical fields the authors are listed alphabetically by last name (the assumption being that each of them made a contribution without which the paper wouldn't exist - so ranking them is not important).
You could investigate that with a few minutes of googling - the 'student' has been writing CS papers since the mid '80s [0]
This reminds me of when someone on HN described both the authors as 'some Israeli CS students' [1]
Whatever you think about this particular paper, the authors are experienced researchers.
