You can read it online here:
ACM Queue approached me a year ago and asked for suggestions on how to make Queue magazine more appealing to system administrators. As part of the process I helped wrangle a number of sysadmins to contribute articles. Some were in the previous issue and you'll see more in coming months. Of course, I couldn't help but write one myself :-).
ACM Queue magazine is published online, but they cross-publish articles into Communications of the ACM (printed edition), which is a magazine I respect and highly recommend. It isn't just for computer scientists!
I welcome your comments on the new article!
