The UK's Introversion Software was proud to tell us that it is “keen supporters of the Linux community” and, therefore, is releasing its third and latest Linux-based game, DEFCON. DEFCON is an on-line, competitive, multiplayer strategy game based around the theme of global thermonuclear war. Inspired by the 1983 cult-classic Wargames, the game “evokes the tension, paranoia and suspicion surrounding the Cold War era”. The player assumes the role of a general hidden in an underground bunker, whose mission is to exterminate the enemy's civilian population while simultaneously disabling the enemy's ability to retaliate. PC Gamer UK described DEFCON as “pure, deep, utterly unconscionable fun”. A Windows version is already available. Introversion should get an award for best URL to boot!
Ever feel like voting your conscience by supporting the Penguin Party rather than settling for the lesser of two “Republicrat” or “Demopublican” evils? To solve this dilemma, alternative (and Constitutional and increasingly popular) voting methods, such as single transferable vote (STV) and instant runoff voting have evolved that allow one to rank candidates in an election. If your Penguin Party candidate has no chance in hell to win, your vote counts instead for your lower-ranked choice who has a shot at winning. Sorting out these voting preferences is the job of OpenSTV, now in version 1.1, an open-source application that tabulates votes according to the respective voting rules. Data generally comes from from paper ballots and is dumped into OpenSTV. The lead developer says that “some of the voting rules have been extensively verified by comparing the results over hundreds of elections against other software”. OpenSTV runs on Linux, Mac OS X or Windows and can be downloaded from SourceForge.
The company you've known as Etnus has rechristened itself as TotalView Technologies, and to celebrate, it has released version 2.0 of its MemoryScape standalone interactive memory debugger. MemoryScape “helps developers identify, inspect and resolve difficult memory problems in C, C++ and FORTRAN, including complex multiprocess and multithreaded programs”, says TotalView. Some key features include tools that allow developers “to monitor heap memory, view memory usage, locate memory leaks, track memory events and show corrupted memory”. Developers also can save and compare memory states, compile memory reports and find memory problems without recompiling. New features in MemoryScape 2.0 include support for MPI programs and remote memory debugging. A trial version is available for download from TotalView's Web site.
Woven Systems has put more than a beach bucket's worth of VC money into its new switch product, the EFX-1000. The end result, says Woven, is the first of a new class of Ethernet Fabric Switches, intended to meet the needs that accompany multicore servers, server consolidation and virtualization, IP storage and data center grids. Ethernet Fabric Switches can be interconnected to build “resilient, low-latency, non-blocking meshed Layer 2 fabrics scaling to more than 4,000 10GbE ports”. The 10GbE EFX-1000 switch “incorporates the performance and low cost of InfiniBand, the reliability of Fibre Channel, and the plug-and-play interoperability of Ethernet”, all at a significantly reduced per-port price. Woven Systems has been dubbed one of the “Top 10 Startups to Watch” by the publication Byte and Switch due to its “potentially disruptive data center technology”, as well as “Cool Vendor” by the Gartner Group.
Xandros' new Server 2.0 just hit the streets and contains new features like integrated OpenDocument collaboration and comprehensive server backup and restore. The OpenDocument collaboration extension, created in tandem with the firm O3Spaces B.V., “provides OpenDocument and MS-Office document collaboration, management and retention services” and serves as an alternative to the Microsoft Office SharePoint server. For server backup and restore, Xandros has integrated SEP AG's “SEP sesam application, which provides comprehensive data security for the Xandros Linux Server, including full integration with its new Scalix 11 collaboration platform”.

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?
