This column is currently busy serving other more-deserving readers. Please wait while we play Wagner's Ring Cycle—or you can piss off quick—who needs you Philistines? You can press #1 for Solti (the default), #2 for Karajan or #3 for Sir Andrew Lloyd Webber. Be warned: #3 is the gotchyer exit that precludes all future re-entry.
We'll “hangup” on you, reminding us that the anachronism has survived wondrously from Homer's misplaced metallurgy (according to Robert Graves, Homer nodded over his iron and bronze age technologies), through Shakespeare's chiming clocks (Julius Caesar), and into our post-vertical ebonite telephony.
We no longer “hangup” the phone, simply bang the bugger down flat. Yet there's still a BEL lurking in the ASCII char-set although gongs per se have been replaced by tones—and even Ma Bell, my ever-pined heartthrob (I had her once in the back of a London taxi), has deserted wire-ridden communications for cable TV and credit cards.
Simple verbs such as “ship” have also suffered the anachronistic “curse”. When X says they'll “ship” Y by Z, or else, I can't help but think of the Titanic, Lusatania, Bismarck and Scharnhorst.
Digging deeper, dear patient reader, Virgil and that crowd, predicted the near-future subjunctive gerundive (whatever) with in navem impositurus esse (to be about to [load] ship), but with the ironical secondary meaning of imponere (to deceive or cheat).
Meanwhile, by the time this column reaches you, Bob Toxen's long-awaited tour-de-force Real World Linux Security—Intrusion Prevention, Detection and Recovery (Prentice-Hall) should have been shipped, nay, airmailed, to a bookshelf or Amazon site near you. I can now reveal the identity of the Mystery Man prefacer hinted at in the pre-pub manuscripts I've been enjoying. No other than Eric Raymond who is much more qualified than moi to test and endorse Bob Toxen's efforts. Further, the book has gained a positive blurb from Steve Bourne, without whose pioneering shell where we would be today?
Check www.cavu.com/book.html for the latest price/availabity news. Security is one of those ever-changing challenges. As Bob told me, he feared his book, like Tristram Shandy's memoirs, could never be completed: “It's killing me and may appear posthumously.”
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
