I also had a paper at this year's CCS conference, so perhaps I can shed some light on the process. The publisher had some fairly picky requirements for the PDFs, and warned that most PDFs created by (for example) pdflatex would probably not pass muster. So along with a PDF we had to submit a Postscript file so that they could distill it into a PDF that met their requirements if necessary. That's likely what happened here--the final Acrobat Distiller step was probably done by the publisher to make everything fit their publishing requirements.

I believe this has been shown incorrect; from the article:

As it turns out, the reason for all those routing resets and general instability was due to a previously unknown Cisco bug involving AS paths close to 255 in length.

(emphasis mine). More info:

And the Cisco description (the bug ID, CSCsx73770, is linked in there, but you need a login to access it):

Last time I installed Ubuntu it still asked for a password for the normal user account. It asked for that same password when it needed to elevate privileges and perform some configuration command as root (via sudo).

So, you have a password, and if you need to you can get root-level privs, but the random everyday stuff you do doesn't have the potential to wipe out the whole OS.

Seems like a win-win to me, really.

Out of curiosity, what did a real root account get you that "sudo -s" didn't?

The iPhone doesn't have support for Linux (no iTunes!), and since it (unlike previous incarnations of the iPod) doesn't function as a standard USB mass storage device, it's effectively useless on that platform. I agree that it's not limited to one, but it is limited to two.

Current workarounds involve jailbreaking your iPhone/iPod and then (I am not making this up) syncing files over SSH.
