Lenny's Looking for Love
Valentines Day. That one day a year when geeks everywhere find themselves whisked away from their terminals for a night filled with flowers, chocolate, and — dare we say it? — romance. This year, however, significant others of the Debian set may find it more difficult to drag their beloved beyond the box, as, barring a lovers quarrel, the Debian community and the long-awaited Debian 5, better known as Lenny, will finally tie the knot.
Nearly nine months ago we brought LinuxJournal.com readers the news that the "we'll release it when it's ready" distribution would finally be uncorking it's tenth vintage, what our esteemed colleague and Chef Français extraordinaire Marcel Gagné might term Chateaudix-du-Lenny. The expected September release — as one might have already guessed — was delayed after the release team determined that too many critical bugs remained in the release candidate. The bugs have now, apparently, been squashed, as Lenny is scheduled to make its debut this Saturday, the "most romantic day of the year," Valentine's Day.
What exactly will Lenny be carrying when it knocks on the Debian community's door? A number of security enhancements, for one, including an update to the Debian Installer which applies security patches before booting for the first time, added GCC hardening for a number of critical security packages, and a reduced number of open ports and setuid root binaries. The server edition — which a recently-released report by heise open found was in use by 47% of the (German) businesses surveyed1 — has added support for the following packages, among others: Python 2.5.2 and 2.4.6, MySQL 5.1.30 and 5.0.51a, PHP 5.2.6, GNU Compiler Collection 4.3.2, Asterisk 188.8.131.52, Samba 3.2.5, the Xen Hypervisor 3.2.1, PostgreSQL 8.3.5, and Nagios 3.06.
Desktop users will find no shortage of upgrades either, including: X.Org 7.3, GNOME 2.22.2, Xfce 4.4.2, KDE 3.5.9 (but not KDE 4.2), OpenOffice.org 2.4.1, Inkscape 0.46, GIMP 2.4.7, GNUstep desktop 7.3, and lxde 0.3.2.1, as well as updated versions of Debian's Icedove & Iceweasel packages, the de-trademarked equivalents of Thunderbird 184.108.40.206 & Firefox 3.0.5. Missing from the release is support for the now-superseded Apache v1, sparc32, and the Linux 2.4 kernels.
Adeodato Simó, a member of the Debian Release Team, told Computerworld that barring a last-minute critical flaw or a technical failure — the loss of a required server, for example — Lenny will arrive amidst the petals and petit-fours on Saturday the 14th. For our part, we wish them smooth sailing sans superstitions for finishing touches on Friday the 13th.

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
