AT&T Software Solutions Division announced the availability of the latest release of David Korn's enhanced shell program for UNIX—POSIX Korn Shell (PKSH), informally called KSH-93 during the early stages of development. PKSH includes many new features and has been designed to comply with the POSIX shell standard. At the same time, PKSH has been enhanced to boost programmer productivity through improved performance and support for re-use and extensions. New features and program improvements include new commands, additional variables, support of associative as well as indexed arrays, and support for compound data objects and discipline functions.
PKSH is available for Linux for $149 for a binary license for one system. Please contact Ed Cartier, AT&T Licensing, (908)580-5719, email@example.com
Applied Information Systems has released its XESS 3.0 spreadsheet product for Linux. XESS is an X Windows product that provides a full complement of spreadsheet functions and graphs, plus many advanced features. It includes a platform-independent API for developing client/server applications that share data in real-time with spreadsheets. A Tcl interface is also available.
XESS is supported on Linux and most Unix and OpenVMS systems. Demonstration versions are available by ftp at ftp.uu.net in the directory /vendor/ais. AIS may be reached at 100 Europa Drive, Chapel Hill, NC 27514; 1-919-942-7801; fax 1-919-493-7563; e-mail firstname.lastname@example.org.
Softfocus formally announced the release of a Linux version of their popular BTree/ISAM file manager. BTree/ISAM is a complete random and sequential file management library written entirely in portable C. Available since 1982, it is currently in use worldwide on a wide range of operating systems and compilers. The distribution includes complete source code, excellent documentation, and technical support through email, phone, fax, and BBS.
“Actually, we've been actively supporting Linux for over a year now,” says Jon Simkins, president of Softfocus, “We take pride in the portability of our software to all robust C platforms and Linux certainly qualifies there. But interest in Linux as a serious development platform has increased dramatically over the last several months and we thought we'd better let the world know that BTree/ISAM v3.1 is Linux compatible.” Simkins added that the low cost and high performance of BTree/ISAM make it very popular with Linux developers.
Simkins is effusive in his praise for Linux. “I first installed Linux last year after one of my clients recommended it. I was immediately surprised by how robust and complete a system this was. Linux is now my principle development system and it's no exaggeration to say I'd be lost without it. The quality of the C development tools made the BTree/ISAM port trivial.”

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
