The new version 11 of Opera, the veteran of Web browsers for Linux, took the next step in its evolution by adding extension functionality. Developers can author, upload and share these browser add-ons, which utilize Opera's APIs, as well as Web standards like HTML5 and JavaScript. These standards allow extensions made for other browsers to be tweaked and shared with 50 million Opera desktop users. Previously, extensions were limited to Opera Widgets and Opera Unite applications. Opera checks all extensions before they are made public to ensure that the catalog of extensions is free from defects and malicious software. Opera 11 runs on Linux, Mac OS and Windows.
The miserly and miniature Linutop PC just got a brain implant in the form of the new Linutop OS 4.0, a small and secure Ubuntu-based operating system. The OS also works on other x86 PCs. Version 4's key new addition is the kiosk configuration, which allows for quick-and-simple customized configuration—for example, in secured public Internet access, digital signage, network monitoring, thin-client use, mini-servers and low-cost desktops in virtualized environments. Other benefits include a small, 700MB footprint, low power requirements and the ability to back up the entire OS on a USB drive.
Farming out services is something nearly all of us have engaged in at some level. If you think you've got the stuff to break out beyond frantic calls from grandma, you may want to pick up Maureen Broderick's The Art of Managing Professional Services: Insights from Leaders of the World's Top Firms. The book is a guide to building and managing a professional service firm. According to Broderick, aspects like infrastructure, governance, talent acquisition and retention, compensation and financial management vary significantly from traditional corporate environments. Furthermore, conventional management advice doesn't offer all the answers, and mainstream business gurus rarely address the unique challenges facing professional service firm leaders. Insights are offered based on 130 in-depth interviews with leaders of the world's top firms.
If embedded Linux is an arrow you want to add to your quiver, take your aim at the new 2nd edition of Christopher Hallinan's popular book Embedded Linux Primer: A Practical Real-World Approach. The publisher Prentice Hall bills the title as “the definitive real-world guide to building efficient, high-value, embedded systems with Linux”. This new edition has been updated to include the newest Linux kernels, capabilities, tools and hardware support, including advanced multicore processors. Topics covered include kernel configuration and initialization, bootloaders, device drivers, filesystems, BusyBox utilities, real-time configuration and system analysis. This edition adds new content on UDEV, USB and open-source build systems.
By releasing its new Smart Technology Platform, a cloud hosting solution for Linux and Windows, Joyent has Amazon's EC2 focused squarely in the crosshairs. Joyent differentiates its product from other cloud platforms by offering “an environment optimized for Web application development” that delivers higher performance in key areas, such as disk and memory I/O, CPU speed and network latency, as well as being “pound-for-pound the most affordable solution on the market for the performance delivered”. The Joyent platform also comes bundled with a full set of integrated solutions.
The data protection solution provider SoleraTec has expanded the functionality of its flagship OnSSI video management system with the new Phoenix RSM Module. This new module extracts and replicates video feeds at high speed while maintaining the original video quality and resolution. By replicating video into the Phoenix RSM forensic storage solution, organizations can greatly expand their retention abilities and provide stronger, comprehensive management of all recorded video. Users quickly can search and play back video footage, regardless of when the video was recorded or where it is stored. Organizations can capture and store huge amounts of video surveillance footage that easily can be searched and retrieved for playback. The optional H.264 lossless format reduces storage requirements up to 70% while preserving original image quality, allowing for greatly increased content on the same storage space.

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?
