The new book Debugging with GDB/DDD by Norman Matloff and P.J. Salzman, published by No Starch Press, highlights the importance of debugging to successful software development. Focusing on GDB, a popular open-source debugger, the book shows developers how to reduce the time they spend finding and fixing programming errors. Debugging's approach is to apply a range of real-world coding errors, from simple typos to major logical blunders, to illustrate how to manage memory, understand core dumps and trace programming errors to their root causes. The book also covers topics missing from other debugging books, such as threaded, server/client, GUI and parallel programming.
Fresh out of beta is Cohesive Flexible Technologies' Elastic Server On-Demand (ESOD) Community Edition virtualization platform. The product is a free Internet platform for independent developers and individual enterprise developers to take advantage of virtualization and cloud computing utilities like Amazon's Elastic Compute Cloud. Users can “take their application stack 'recipes', capture them, and reproduce them as virtual servers rapidly and automatically”, says CohesiveFT's CTO. The firm claims to be the “first service to offer developers and operations complete control of their server assembly, independent of which virtualization or cloud technology they require.” The ESOD Community Edition is free to use and is intended for individual developers and noncommercial, nonproduction use.
Adding to its rich portfolio of debugging tools, TotalView Technologies has released Workbench Manager, an application that allows developers to create an integrated, cohesive view of the development and debugging work-flow process. One can manage any version of TotalView Debugger, MemoryScape memory debugger and any third-party application used for development and debugging, all from a single dashboard-like GUI. As a result, you easily can integrate both commercial and open-source tools in your toolchain. TotalView Technologies' products can be used to debug Linux, Mac OS X and UNIX applications running on development machines with single, dual-core, multicore or multiple processors.
A book on a specific Linux topic typically means it's on the cusp of breaking out. Such is the case with Geographic Information Systems (GIS), the focus of the new book Desktop GIS: Mapping the Planet with Open Source Tools by Gary E. Sherman and the Pragmatic Bookshelf. The book's purpose is to help you deal with the issues involved in assembling your GIS toolkit, such as choosing the right platform and tools, dealing with integration issues and getting support. Sherman introduces the main open-source applications, such as GRASS, Quantum GIS, uDig and others, and also delves into scripting with various languages. The author is the founder of the Quantum GIS Project.
New on the development scene are SoftIntegration's Ch 6.0 and Embedded Ch 6.0, interpreters for cross-platform scripting, 2-D/3-D plotting, numerical computing, shell programming and embedded scripting. New features in v6.0 include debugging capability, a user-friendly IDE for teaching/learning programming (in the Professional Edition) and new plotting features, including multiple coordinates and new plotting types. Ch and Embedded Ch are available for Linux x86, Linux PPC, Windows, Mac OS X, Solaris, HP-UX, FreeBSD and QNX Neutrino RTOS.
ADLINK Technology has just beefed up your options for network security, adding the ALS-3206 Rackmount Network Security Platform to its solutions palette. The ALS-3206 series is billed as a flexible, mid-range, cost-effective solution for IDS, IPS, UTM, firewall, VPN gateway, load balancing and traffic-mining applications. The line further supports several Intel processors and chipsets and provides six gigabit Ethernet ports, one PCI extension slot and two configurable PCI-X slots. One of the PCI-X extension slots can be configured to extend a four-port gigabit Ethernet card and the other to extend a network security accelerator. This combination of features is suited, says ADLINK, for antivirus software security, content security and PKI software applications.

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?
