Hot and fresh from SystemBase's ovens are the new Eddy v2.1 Series embedded CPU modules for high-speed serial communication with real-time Linux. These small, Linux-ready 32-bit ARM9-based modules support high-speed RS-232, RS-422 and RS-485 serial interfaces at up to 921.6Kb/s, tolerate an extended temperature range (from –40°C to +85°C) and are equipped with Ethernet and wireless interfaces. SystemBase says that developers can set up their designs on the Eddy-DK v2.1 hardware development kit and the software development environment LemonIDE for Lemonix. Lemonix is an embedded, real-time Linux operating system that has been revised to support real-time capabilities while retaining the stable traits and merits of the Linux kernel 2.6.x.
If Java's your gig, take note of the latest v6.0 release of Instantiations' CodePro AnalytiX, a code-review tool for Eclipse Java. Instantiations asserts that CodePro AnalytiX's new product features will “help developers decrease potential code security vulnerabilities early in the software development life cycle, improve Java code quality and reduce development costs through increased developer productivity”. Core product features include code audit, metrics, automated unit tests and team collaboration. New features include 25 new OWASP-based rules; two new audit-rule categories (Web services and threads and synchronization), mock objects to simulate the behavior of other objects safely and JUnit testing support for more Web application frameworks. JUnit test generation now supports most popular frameworks, including Spring, Struts and Enterprise Java Beans.
Although the title of Shai Vaingast's new book Beginning Python Visualization tells you something, the subtitle, Crafting Visual Transformation Scripts, perhaps tells you even more. Author Vaingast says that we are “visual animals” whose brains must sort, organize and transform data into images “before we can see the world in its true splendor”. Part of Apress' Beginning Series, Beginning Python Visualization illustrates how to turn many types of small data sources into useful visual data. Learning Python is simply an added bonus. Readers will learn to set up and use an open-source environment as an alternative to Excel for data visualization. The book is for IT personnel, programmers, engineers, hobbyists and others who are interested in acquiring and displaying data from sources such as the Internet, sensors, economic trends, astronomical sources and more.
Thanks to past efforts of LJ founder Phil Hughes, Drupal holds a special place in the hearts of our editors. Thus, I will preach the good Drupal word by informing you of Victor Kane's new book Leveraging Drupal: Getting Your Site Done Right. Publisher Wrox calls Leveraging Drupal “much more than a tutorial” and a “nuts-and-bolts living mentor and guide” that explains how to do what is really required to build a site that works. Kane's book covers Drupal topics such as theming, customization and best practices in Web development while including videos and code and theme samples at every step. Advanced topics include views, panels and content creation.
The company ToutVirtual bills itself elegantly as an “emerging leader” in virtualization based on its product VirtualIQ Pro. Now in version 3, the product is “a single, platform-agnostic management and automation console” for virtualization deployment, says the company. VirtualIQ installs on Linux and Windows and provides features such as server-virtualization assessment, asset management, performance management, capacity management and reporting, together in one product. Users can support Xen, Citrix, Microsoft, Oracle and VMware virtualization platforms from one console. New features in Version 3 include an updated UI, physical and virtual asset and inventory discovery, a physical-to-virtual migration analyzer and virtualization analytics. A free version supporting up to five CPU sockets or 25 virtual machines is available for download from ToutVirtual's Web site.

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
