comment Does using noatime on modern Linux make sense?
Good question and sadly there is no simple answer. I would rather hope that applications that rely on atime would call this out in README, installation or FAQ documents. Historically one of the main users of atime relative to mtime has been file based mail user agents (MUA) to keep track of what has and hasn't been read since deliver. My approach has often been to just disable atime modification and keep an eye out for anything that breaks. Historically I have left /var with relatime tracking turned on but on newer installs I've tended to turn it off.

comment Why IP address for Linux Bridge which is layer 2 virtual device?
I am a little reluctant to trim all but the 2nd sentance. The first sentence answers the first line of your question. Admittedly the way to setup an IP-less interface on Debian/Ubuntu is only mildly related to your question so that could likely be deleted if considered too off-topic.

Note the "." characters in the text representation are typically placeholders for byte values that do not have a corresponding printable character associated with it.

comment Rotating a video (ubuntu 12.04)
I tried the first ffmpeg command on a few mp4 and mpg files I have here. It worked fine on both Ubuntu 12.04 and 12.10. So as @evilsoup says it might be an issue with the specific video file you have.

comment Why can't I copy my DVD with dd?
Really the only way to determine if the final image is "corrupted" is to work out if it is usable. Part of that will be making sure that only the actual broken blocks are read as zeros and none of the surrounding blocks. That might mean that you need to pass a bs=512 (from memory that is the CD/DVD blocksize) parameter to dd. Really though that sort of thing is what dd_rescue is designed to do. It might take time but it tries to lose the minimum amount of data possible.
