Automating Unix and Linux Administration
nead writes "If you are disciple in the church of Wall, or like me you believe that laziness is the father of invention, or if you simply have more than a couple *nix machine to administer, Kirk Bauer's new book Automating Unix and Linux Administration is definitely for you. From the creator of the popular open source projects AutoRpm and LogWatch comes a thorough - and believe it or not entertaining - look at how one can leverage the power of a few common tools to significantly reduce the time and effort system administrators spend doing their jobs." Read on below for the rest of nead's review. Automating Unix and Linux Administration author Kirk Bauer pages 547 publisher Apress Inc. rating 8.0 reviewer Nick Downey ISBN 1590592123 summary Tools and methods for automating *nix administration for a couple (or a few thousand) computers.From the outset, Bauer takes a straightforward and principled approach to problem analysis. Usually starting with anecdotal example scenarios (many of which will have you saying "been there before") and progressing through ideals, goals and consequences, he examines many of the common issues facing system administrators with candor and realism. Almost nowhere in the book does the author assume an authoritarian stance; he questions his own decision making process and encourages the reader to come up with exceptions to his rules. Fundamentally Bauer has one goal -- to develop a comprehensive system for reliably automating the tedious but important tasks that all system administrators face on a recurring basis.
Admittedly, it would be a fallacy for any book to claim complete and comprehensive coverage of all things related to system administration and Bauer does no such thing. When the author touches on topics that obviously require more depth than a single chapter can afford, he is certain to include at least one reference (and in many instances more) to alternate publications without bias to any particular publisher or author. Having said that, the book's scope and depth of topic coverage is impressive. Starting with an exhaustive examination of SSH and progressing through cfengine, NFS, LDAP, RPM and Tripwire (just to name a few) Bauer provides carefully detailed instruction on how to automate tasks ranging from simple network management and software packaging to security, monitoring and backups. The author even goes so far as to suggest methods for efficiently front-ending automation systems for the less technical of users.
Although not expressly stated in the text, the overall theme of the book is walk on the shoulders of giants. Starting with simple example scripts (in both Bash and Perl) and many single-line commands, Bauer builds on the content of each previous chapter as the book progresses. Examples shown in early chapters are incorporated into more complex systems one step at a time. Following along is easy, each script or command is detailed on a line-by-line basis, and because of Bauer's principle-based approach the reader is rarely left wondering why the author has chosen a particular tool or implementation. More often than not the elegance of how Bauer pieces together methods and procedures will excite you about the possibilities for automation of your own systems.
Although Bauer explicitly states that readers are presumed to have more than a modicum of experience in system administration, even the novice administrator, as well as those that are responsible for only a handful of machines, will find this book invaluable. Also included are three appendices which provide an easy introduction to basic shell tools, creating your own RedHat distribution and how to package software as RPMs. These portions of the book alone justify the less than $40 price tag, but for those who run clusters or data centers, this book stands to save you countless hours of repetitive headaches. Published by apress and boasting nearly 600 pages, this lively read has made itself a permanent addition to at least one reference library.

Postmodern Computer Science
gnat writes "Two New Zealand computer scientists have a paper accepted for OOPSLA called Notes on Postmodern Programming, which identifies shortcomings in traditional views of computer science. With a section on the difference between "The Matrix" and the net, a bulleted list of new approaches called "We're All Devo", and a section called "Messy is Good" consisting of nothing but a scan of a hand-drawn diagram, this is not your father's computer science paper. It's thought-provoking stuff, though. And you know they did their homework--they cite Larry Wall's Postmodern Perl talk." -
3rd State of the Perl Onion
Geoff Eldridge writes " Larry Wall has made available a copy of his 3rd State of the Perl Onion which he recently delivered. You will need a basic grounding in molecular chemistry to understand this year's onion." Larry is (as always) pretty dang wierd. But it is nice to know that the end of cobol is iminent. -

Perl and Postmodernism
An anonymous reader sent us a link to Perl and Postmodernism which is Larry Walls speech at LWCE (which I missed despite the fact that it was the only speech that I really wanted to see). If you enjoy Wall's stuff, you'll dig it. If you don't, you won't. I'm in the former group personally.
