Perl 5.8.0 www.perl.org
Reuven Lerner covers a different web development tool every month but keeps coming back to good old Perl. In the new version, he writes, “Most important is its support for threading and Unicode, both of which will help to propel Perl forward for years to come.” We like browsing the Comprehensive Perl Archive Network (CPAN) for modules that empower a short script to do exactly what you want.
Reuven also is a fan of PostgreSQL, a database that makes its fair share of appearances in our pages. “The PostgreSQL team has demonstrated that it is possible to produce a database with the price and ease of administration of MySQL, but with the feature set of Oracle. The only real competition is Firebird and SAP DB, both of which might make serious inroads in 2003–2004”, he writes.
The new 7.3 version offers table functions (functions that return multiple rows), schemas and prepared queries, as well as Unicode by default, improved logging and nonlocking vacuuming of tables.
Marcel points out that “What we need, however, is a dead-simple database application for new users who might simply want to create a Christmas card list or whatever. Just because we can create a full-blown relational SQL database and have it for free, doesn't mean it is always what the user needs.”
Marcel calls Webmin “a wonderful, low-resource tool that crosses distros and operating systems” and praises the integrated SSH application. Webmin standard modules can be used to administer any server software you can imagine, from Apache to voice mail to WU-FTP. Third-party modules make it easy for ISPs to delegate mail and virtual web host administration to customers.
Lindows Mobile PC www.lindows.com/lindows_feature_preinstall.php
Finally, a notebook computer with Linux pre-installed. Doc Searls would be happy with this box, based on a VIA processor and equipped with 256MB of RAM and all the expected extras, if he could get it away from his six-year-old kid.
Frozen Bubble www.frozen-bubble.org
Move along, people, nothing to see here, back to work. This could be the next Tetris. You won't often hear this from us, but whoever ported this thing to Microsoft Windows and Mac OS, thank you, because now it won't be only Linux users' productivity down /dev/crapper. New in version 1.0: 100—yes, 100—levels and a level editor.
Understanding the Linux Kernel, 2nd Edition by Daniel P. Bovet and Marco Cesati www.oreilly.com/catalog/linuxkernel2
This is a good one to keep handy if you get stuck on something in Kernel Korner, or if you dig building custom kernels and want to know how things work. We won't say which of the contributing editors voted for their own books.
Linux Weekly News lwn.net
Everybody's doing metanews—selecting the best articles from every news site—but Linux Weekly News does a good job of filtering the important Linux news from the drivel. And, they offer original content on diverse topics such as security alerts and kernel hacking—something to keep you happy between issues of Linux Journal.
Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
