In an effort to expand the reach of the newly open Symbian platform, Open Kernel Labs has released OK:Symbian, an open-source, ready-to-run, paravirtualized version of Symbian. OK:Symbian enables the Symbian platform to be used as a guest operating system running in a secure hypercell on top of the OK Labs OKL4 microvisor. Open Kernel Labs says that its HyperCell Architecture allows for higher levels of security and robustness and enables the use of the Symbian platform in new lower-cost devices and in new ways. OK:Symbian also lets handset OEMs, MNOs and mobile-phone users benefit from the tens of thousands of existing Symbian applications and the global developer community for the platform. In related news, Open Kernel Labs announced its joining of the Symbian Foundation, as well as its contribution of OK:Symbian to the Symbian Open Source community.
The new Openbravo ERP 2.50 was recently released by its eponymous parent company. In the new 2.50 version, the Web-based, open-source Enterprise Resource Planning (ERP) and Point of Sale (POS) solution for businesses is now available as a professional subscription service. The new release also introduces a modular architecture and adds a host of new features and functions, such as support for right-to-left languages (such as Arabic and Chinese), additional smart-build processes, autosave, more user alerts and enhanced support for complex organizations. Furthermore, Openbravo states that it is easier than ever before for the community and third parties to customize and create their own new features and functions. One can browse and use shared functionality created by other users or deploy third-party modules shared on the new Openbravo Forge.
The Marketcetera open-source platform for automated trading recently announced a significantly upgraded version 1.5. According to Marketcetera, stock-market data volumes are exploding and “automated trading is becoming more prevalent on the buy side and across more asset classes, not just equities”. The company also says that its application helps investment firms make fast, intelligent trading decisions at lower costs per transaction. New features in the latest release include real-time intraday position and profit-and-loss monitoring; simplicity and security for multiuser installations; Level 2 and depth-of-book market data and strategy agent integration via the new Strategy Studio.
The news out of LinMin is its upgraded version 5.4 of LinMin Bare Metal Provisioning, a system provisioning and imaging solution that can be implemented by IT organizations of any size with limited budgets. Combining server provisioning and disk imaging in a single product, LinMin is a solution for deploying, repurposing and recovering the commodity hardware infrastructure layer used in hosting, corporate, cloud and other data-center environments. LinMin says that the new release adds the “Turbo-Imaging” high-performance disk imaging subsystem for disaster recovery, new operating system media management, updated Linux and Windows Server provisioning, extensive logging and others. The firm also adds that Turbo-Imaging adds automatic filesystem detection, intelligent compression and other capabilities to ease the rollback of systems back to a known good state.
The good folks at Talend have released the Talend Integration Suite MPx, a new enterprise data-integration platform that the company says “is designed to help organizations attain the highest levels of performance and shatter the limits typically associated with traditional data integration processes”. The solution is based on the Talend Integration Suite while adding the new FileScale technology, a breakthrough that allows organizations to conduct highly parallelized processing and reduce limitations inherent in traditional data-integration architectures. It further allows integration processes to sort, filter and merge data, perform aggregation and arithmetic functions, and transform and ensure the compliance of data. Finally, the new package features multiple levels of massive parallelization, allowing the execution of separate subprocesses in parallel, breakdown of data sets into many parallel streams and the ability to leverage parallel database loaders.

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?
