Were you a LEGO-lover as a kid? If so, Radical Breeze thinks you'll find its new Illumination Software Creator 1.0, a visual software application builder, extremely intuitive. A user—even a non-programmer—can easily experiment with software building blocks, in a completely visual and understandable way, and create software that can be run on Linux, Mac OS X and Windows computers. The application converts visual concepts into source code. No virtual machine is involved. In addition, software built with Illumination Software Creator can be run as a rich Internet Web page or an Internet tablet application (for Nokia Internet Tablets). The languages utilized are Python and GTK for desktop and mobile applications, and JavaScript for Web applications.
Our old friend Robert Love, whose popular Kernel Korner column long graced these pages, has updated his classic book Linux Kernel Development to a new 3rd edition. Published by Addison-Wesley, this work details the design and implementation of the Linux kernel, presenting the content in a manner that is beneficial for those writing and developing kernel code, as well as for programmers seeking to better understand the operating system and become more efficient and productive in their coding. The book details the kernel's major subsystems and features, including its design, implementation and interfaces. It covers the Linux kernel with both a practical and theoretical eye, which is intended to appeal to readers with a variety of interests and needs. Updated content includes an all-new chapter on kernel data structures, details on interrupt handlers and bottom halves, extended coverage of virtual memory and memory allocation and more.
Hosting service providers may want to read on about the new LVE Wrappers from CloudLinux, tools that let the server owner control the exact CPU usage for individual users and applications. LVE Wrappers are based on CloudLinux's Lightweight Virtual Environment technology that allows administrators to control CPU usage on a server at the tenant or application level. It does so by isolating specific hardware resources in a lightweight container and prevents one tenant on a shared server from affecting others. LVE Wrappers, which start individual applications and dæmons inside LVE environments, allow for control of resources for each application, which allows for greater flexibility and stability on the overall server infrastructure. The software is available to all CloudLinux subscribers.
Authors Tony Mullen and Claudio Andaur have set out to prove that the amazing open-source 3-D animation software Blender isn't just for hobbying anymore. Their new book Blender Studio Projects: Digital Movie-Making, now out from Sybex, shows readers how to do on Blender what one typically has done with high-end (and high-priced) apps Maya and 3ds Max. Sybex bills the book as “a real-world, roll-up-your-sleeves guide that plunges straight into step-by-step instructions designed to help you build skills and create solid assets for film, video and games.” The companion DVD includes starter, intermediate and final files, as well as movie files to help you every step of the way.
Managing ERP apps can require the patience of Job, which is why CAST Software released its new Analysis and Measurement Software for SAP, Siebel and PeopleSoft. The product's mission is to bring consistent and objective measurement of these platforms and eliminate costly customization errors in critical business applications. CAST's own studies of ERP installations showed a large percentage of issues that normally go undetected in functional testing and result in serious performance, stability and maintainability problems. For instance, 80% of database interactions in ERP installs are handled improperly, leading to significant business disruption. Environments like SAP, Siebel and PeopleSoft, says CAST, require a deceptively high level of customization. Because manual measurement of quality is expensive and time consuming, automation is useful for exposing flaws that cause applications to perform erratically.

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?
