New Products
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.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
