In any discipline, the road to true mastery and wisdom requires a comprehensive view. If programming is the discipline in which you seek such mastery, crack open Bruce A. Tate's new book Seven Languages in Seven Weeks, A Pragmatic Guide to Learning Programming Languages. The book has what publisher Pragmatic Bookshelf calls an “audacious goal”, which is to present a meaningful exploration of seven languages—namely Clojure, Haskell, Io, Prolog, Scala, Erlang and Ruby—within a single book. Seven Languages covers what's essential and unique about each language and the most critical programming models of our time. For each language, readers solve a nontrivial problem, using techniques that show off the language's most important features, strengths and weaknesses.
Jothy Rosenberg and Arthur Mateos' penned the new book The Cloud at Your Service because the market needed a book on cloud computing targeted at corporate decision-makers. The book, which is subtitled “The when, how, and why of enterprise cloud computing”, seeks to inform managers, buyers, enterprise architects, CIOs and CEOs on the what, when and how of moving to the cloud. It is the book the authors wished they had when they were in that role. Cloud-computing-related topics include an introduction, the business case, private clouds, designing and architecting for scale and reliability, practical considerations, deployment and operations and a look into the future of cloud computing.

Symantec recently released two new solutions for VMware environments—that is, ApplicationHA and VirtualStore, which the company says “will enable organizations to virtualize their mission-critical applications and minimize their storage costs on the VMware platform.” Symantec ApplicationHA, which is based on Veritas Cluster Server technology, provides high availability for business-critical applications through application-level visibility and control in VMware environments. Meanwhile, the Symantec VirtualStore, based on Veritas Storage Foundation technology, is a software-based storage management solution for VMware virtual machines that provides rapid provisioning of servers and virtual desktops, efficient cloning and accelerated bootup of virtual machines. Both ApplicationHA and VirtualStore are integrated seamlessly with VMware management tools, such as VMware vCenter Server, enabling customers to deploy these tools without impact to their operational models.

Free Webinar: Hadoop
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?
