Mandriva bills its new Enterprise Server 5 (MES 5) as “simple and innovative”, combining the best of Linux (reliability, security, low admin costs) with the best of Mandriva Linux (easy to use, exclusive Mandriva tools and professional services) for the administration and integration of servers. The most noteworthy new feature in the update is increased scalability in virtualization, driven by the added kernel-based Virtual Machine (KVM) technology. Other new features include the integrated Mandriva Directory Server, reduced bootup times, increased modularization to allow easier configuration of specialized servers and reduced energy consumption, among others.
Terracotta's Ehcache, a popular open-source, enterprise-level caching solution, has added a new feature set wrapped in its latest 2.0 release. Terracotta says that Ehcache 2.0 adds enterprise-class capabilities of high-priced and proprietary technologies like Oracle Coherence without requiring application changes. Furthermore, this release brings instant scale to the majority of Java applications without code changes or costly database upgrades. Additional new features simplify the development effort, testing and scale-out, such as an express mode that easily clusters application data via configuration changes. Finally, a series of enterprise features better integrate Ehcache with the database, such as JTA for transactions and data write-behind to increase performance while avoiding database bottlenecks.
Embedded developer 6WIND's newly upgraded 6WINDGate, a packet processing application for networking and telecommunications systems, adds new features, such as ten-fold acceleration of packet processing functions and support for the multicore, embedded Intel Xeon processors EC5549 and E5645. The 10x speed-up compared to a standard Linux implementation allows customers to reuse their existing application software and accelerate their time to market. 6WIND further adds that the 6WINDGate SDS profile is optimized for platforms in which the networking Fast Path runs on dedicated cores without the overhead of a Linux-based Slow Path. 6WINDGate's architecture removes the complexity of integrating high-performance packet processing with the Linux environment, because it fully synchronizes the Fast Path and Linux, while preserving Linux APIs. It includes complete Layer 2 through Layer 4 embedded networking features (routing, IPsec, firewall, QoS, NAT, multicast and so on), reducing development time by as much as 70%.
“Who said dragon slaying was easy?” is author Scott F. Andrews' Bilbo Baggins-esque invitation to try his new book The Guild Leader's Handbook, a guide to leading a guild in massively multiplayer on-line (MMO) games. Subtitled “Strategies and Guidance from a Battle-Scarred MMO Veteran”, the book outlines not just how to create, build and maintain a successful guild but also how to lead it to glory. Andrews should know, because he leads one of the oldest-surviving guilds in World of Warcraft. He shares secrets from his long experience to illustrate how to plan successful raids, player vs. player battles, role-playing sessions and contests; deal with problem players and keep a lid on guild-fracturing drama; solve loot issues and choose the best loot system; boost morale, reputation and server presence; and promote and motivate an effective officer corps. The Guild Leader's Handbook is published by No Starch Press.
The Swedish firm Imsys proudly announced a new generation of its SNAP Classic module, a drop-in replacement for the DSTINI390 reference design—a Java-based networked controller. Using the same module size and interfaces, the SNAP Classic provides all interfaces supported on the TINI platform. The new SNAP Classic offers greatly improved performance while reducing cost and power consumption, retaining all the legacy and adding new compelling features. For heavy-duty, floating-point computations, SNAP Classic now offers a performance increase of more than 200 times that of TINI, says Imsys. A “crypto engine” consisting of 27 new opcodes supports ARC4, DES, AES, RSA, MD5, SHA1 and SHA256, accelerating them by a factor of up to 43 times compared to their C code implementations on the same processor. For development, the SNAP Classic user can use either free Java tools or purchase the optional Imsys Developer, a professional IDE that enables the developer to use a mix of Java, C and assembler programming.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
