In May, Wolfram Research released Wolfram|Alpha, the world's first computational knowledge engine, which free on the web. Alpha, while not exactly a search engine, is considered a new paradigm that could challenge Google and other leading search engines.
Wolfram|Alpha draws on scientist Stephen Wolfram's groundbreaking work on Mathematica, the world's leading technical computing software platform, and on the discoveries he published in his book, "A New Kind of Science."
The long-term goal of Wolfram|Alpha is to make all systematic knowledge immediately computable and accessible to everyone. Wolfram|Alpha draws on multiple terabytes of curated data and synthesizes it into entirely new combinations and presentations. The service answers questions, solves equations, cross-references data types, projects future behaviors, and more. Wolfram|Alpha's example pages and gallery show a few of the many uses of this new technology.
Finding Wolfram|Alpha Easter eggs has become a popular topic on Mashable, the social media news guide and Facebook users have been helping each other suggest and correct inputs.
"Fifty years ago," said Stephen Wolfram, the founder and CEO of Wolfram Research, "when computers were young, people assumed that they'd be able to ask a computer any factual question, and have it compute the answer. I'm happy to say that we've successfully built a system that delivers knowledge from a simple input field, giving access to a huge system, with trillions of pieces of curated data and millions of lines of algorithms. Wolfram|Alpha signals a new paradigm for using computers and the web."
Wolfram|Alpha is made up of four main "pillars" or components:
* Curated Data: Wolfram|Alpha contains terabytes of factual data covering a wide range of fields. Teams of subject-matter experts and researchers collect and curate data, transforming it into computable forms that can be understood and operated on by computer algorithms;
* Dynamic Computation: When Wolfram|Alpha receives a user query, it extracts the relevant facts from its stored computable data and then applies a collection of tens of thousands of algorithms, creating and synthesizing new relevant knowledge;
* Intuitive Language Understanding: To allow Wolfram|Alpha to understand inputs entered in everyday language, its developers examine the ways people express ideas within fields and subject matters and continually refine algorithms that automatically recognize these patterns;
* Computational Aesthetics: Wolfram|Alpha also represents a new approach to user-interface design. The service takes user inputs and builds a customized page of clearly and usefully presented computed knowledge.
Wolfram|Alpha has been entirely developed and deployed using Wolfram Research Inc's Mathematica technology. Wolfram|Alpha contains nearly six million lines of Mathematica code, authored and maintained in Wolfram Workbench. In its launch configuration, Wolfram|Alpha is running Mathematica on about 10,000 processor cores distributed among five colocation facilities, using gridMathematica-based parallelism. And every query that comes into the system is served with webMathematica.
The Wolfram|Alpha launch process has been broadcast live on Justin.tv and documented on the Wolfram|Alpha blog and on its Twitter and Facebook accounts. During the testing period leading up to the launch, Wolfram|Alpha processed 13.7 million queries.
For more information on the launch of Wolfram|Alpha, see the blog at: http://blog.wolframalpha.com/2009/05/15/live-from-champaign/#more-445

Red Hat has announced the availability of JBoss Enterprise Business Rules Management System (BRMS), an open source business rules solution that enables easier business policy and rules development, access, and management and allows customers to update applications and processes with business rules and policies. Automating business decisions with JBoss Enterprise BRMS can enable business process stakeholders to rapidly implement change.
Business rules are parameters that describe how an organization performs work. Best practices require business rules to be maintained separately from the software applications and services they govern in order to maximize agility. If business rules are duplicated or scattered across many applications, updates are costly, error prone, and take weeks or months to implement. With JBoss Enterprise BRMS, enterprises can update their business rules to reflect the day-to-day business and regulatory environment as quickly as in a few hours. Additionally, a BRMS enables non-technical staff to manage business processes without programming.
"The combination of tight budgets, the increasing maturity of the BRMS, and the continual improvement of open source technologies creates a nearly perfect disruptive storm in the BRMS market," said Stephen D. Hendrick, Group Vice President for Application Development and Deployment Research at IDC. "Open source BRMS products that get rule authoring, processing, and management right combined with a significantly lower TCO will receive a strong positive reception in the market."
JBoss Enterprise BRMS is an enterprise-ready open source business rules management system which can be deployed with other JBoss Middleware such as JBoss Enterprise SOA and Portal.
Key JBoss Enterprise BRMS features include: a Business Rules Engine which can be updated through a range of tools, from editors and spreadsheets to Eclipse; Web 2.0 Rules Authoring and Management Tools with a Rich Internet Application (RIA) user interface; and a BRMS Repository which enables version control of business rules artifacts, including fact models, enumerations, functions, domain specific languages (DSL) definitions, rules and tests.
JBoss Enterprise BRMS adds to Red Hat's overall portfolio of middleware products that help application development, deployment and integration.
Additional information on the JBoss Enterprise BRMS is available online at http://www.jboss.com.

Ixia a provider of IP performance test systems, has announced the IxVM product suite that enables data center managers to assess virtual infrastructure performance and capacity. IxVM builds on Ixia's industry-leading library of layer 2-7 performance test tools.
Ixia's new suite of IxVM products can test layer 2/3 virtual network resources and layer 4-7 virtual applications. IxChariot VM, a component of IxVM, uses software endpoints - small software components that run on each virtual machine - that send and receive test traffic, while measuring performance. This makes it possible to source traffic from virtual servers in the same manner as the supported applications. IxExplorer VM uses software endpoints to generate layer 2/3 traffic to test features such as VLAN and QoS.
"In our rush to cash in on the benefits of virtualization, we seem to have overlooked the problems associated with assessing the end to end performance of virtualized networks," said Zeus Keravala, Senior Analyst at Yankee Group. "IxVM provides the vantage points for emulating and measuring system performance down to the virtual component. Ixia has demonstrated strong leadership and claimed first mover advantage by filling this gap with their virtualization test initiative."
* performance testing of thousands of VMs simultaneously with real world application traffic;
* independent measurement and convergence testing of VM migration;
* tuning of virtual resources such as servers and NICs;
* measurement of key performance indicators like delay, jitter or packet loss through virtual switches;
* testing of network performance variances when running applications over different operating system.
IxVM presents an aggregated performance view. Integrating with VMware, IxVM automatically discovers the components of the virtualized architecture. Pre-deployment testing can compare and contrast performance from alternative configurations or evaluate performance when applications are moved between virtual machines and could uncover dynamic bottlenecks that may be unanticipated.

WSO2, an open source SOA company, has launched WSO2 Data Services 2.0. The completely re-architected open source WSO2 Data Services product is now based on WSO2 Carbon, a componentized service-oriented architecture (SOA) framework.
The modular WSO2 Data Services 2.0 product enables database administrators (DBAs) and database programmers to create and manage WS-* style Web services and REST-style Web resources using enterprise data. It is based on the WSO2 Carbon framework, in which all major features of WSO2 SOA middleware products have been developed as pluggable Carbon components. Users no longer need to deploy WSO2 Data Services 2.0 and the WSO2 Enterprise Service Bus (ESB) 2.0 as separate products. Instead, users can simply add the WSO2 mediation component to WSO2 Data Services.
"WSO2 Data Services addresses the demand among enterprises to quickly and easily take data from a wide variety of sources and expose it as Web services within their SOAs,"said Dr. Sanjiva Weerawarana, founder and CEO of WSO2.
Customization can range from simply reformatting the Data Services logs into a preferred format to writing a bridge application that allows the Data Services server to be remotely managed--and even restarted--via a mobile phone.
Other new features in WSO2 Data Services 2.0 include:
* Enhanced administration user interface;
* WS-Policy Editor to configure services using the W3C standard;
* Support for event-driven architectures (EDA);
* One front-end server to be used to administer several back-end servers simultaneously.
WSO2 Data Services supports access to data stored in relational databases such as Oracle, MySQL and IBM DB2 (virtually any database accessible via JDBC), as well as the comma-separated values (CSV) file format, and Excel spreadsheets. Services can be authenticated, encrypted and/or signed using the WS-Security and HTTP security standards, and support for WS-ReliableMessaging provides enterprise-level reliability.
WSO2 Data Services 2.0 is now part of the WSO2 Carbon SOA framework, based on the OSGi specification, that provides all WSO2 Carbon SOA components with enterprise-class management, security, clustering, logging, statistics, tracing, and a "Try-It" wizard that makes it simple to instantly test data services. Additionally, WSO2 Data Services uses the graphical unified management console, which supports all Carbon components and provides enhanced administration. Any components added to WSO2 Data Services 2.0 are automatically recognized by the core Carbon platform and unified management console
WSO2 delivered its online course "Introduction to Data Services"for free in May. As a special promotion, the usual $199 course fee was waived. Check http://wso2.com/training/ to see if the course is free again in June or July.
As a fully open source solution released under the Apache License 2.0, WSO2 Data Services does not carry any software licensing or subscription fees.

At Citrix Synergy in May, Citrix Systems announced a variety of new offerings for its Citrix Cloud Center (Citrix C3) product family to further equip service providers with the infrastructure and product licensing needed to deliver successful clouds services to their customers.
The updates to the Citrix C3 product family enable service providers to create secure multi-tenant cloud infrastructure environments in a cost effective manner. New capabilities include:
* Citrix XenApp and Citrix XenDesktop - The addition of these two
products into Citrix C3 enable service providers to take their
Infrastructure as a Service (IaaS) offerings to a new level and even
deliver Windows Desktops as a Service (DaaS);
* The CSP program - The CSP program is designed for service providers who provide hosted software services to end-user customers who are not the licensee. The CSP program extends to service providers the "right to use" Citrix products as a monthly "active subscriber". Service providers only pay for actual end-user usage;
* Citrix NetScaler VPX - A virtual appliance version of Citrix NetScaler, the new Citrix NetScaler VPX will be added to Citrix C3, enabling service providers to run multiple NetScaler instances simultaneously and provide cost-effective multi-tenancy web application delivery. In addition, service providers can use "cloud balancing," which allows load balancing across multiple cloud infrastructures;
* Citrix XenServer - XenServer will soon be enhanced with a new distributed virtual switch add-on to enable secure, multi-tenant public clouds. The switch will partition network traffic on a per-application basis, with resource and security guarantees, and offer full visibility into and control over inter-VM traffic within a server and virtual network overlay.
Citrix is now providing Citrix C3 Lab Blueprints, giving IT professionals a set of common scenarios to test, architectural overviews, deployment guides, tips and tricks and discussion forums.
Citrix C3, with XenApp and XenDesktop, and a technological preview of NetScaler VPX are available for free download from Citrix.com. A technological preview of XenServer virtual switch for XenServer 5.5 will be available for free download from Citrix.com on June 1, 2009. Access to the Citrix C3 Lab and Citrix C3 Lab Blueprints is available now at: http://community.citrix.com/display/cdn/Citrix+C3+Lab.
Citrix Systems announced a new cloud solution called Citrix C3 Lab that allows companies to use Amazon Web Services (AWS) as part of their technology infrastructure. This announcement comes in response to the growing demand by organizations to use virtualization technologies to deploy, maintain and access business applications and desktops in more flexible and efficient ways through the Internet.
Based on Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3) and Citrix Cloud Center (Citrix C3) technologies, this new cloud-based lab environment allows IT professionals to prototype future cloud projects today.
Citrix C3 Lab is designed to provide an inexpensive, preconfigured environment for IT professionals to prototype solutions and includes technical components required to create a robust application delivery center in the cloud. Initially, lab users will have access to Citrix XenApp alongside key Citrix C3 technologies such as Citrix Access Gateway and Citrix Repeater in the AWS cloud environment. Citrix is also providing Citrix C3 Lab Blueprints.
Citrix C3 Lab is available immediately and there is no additional charge for running Citrix C3 Lab instances in Amazon EC2 - all a Citrix customer needs to do to get started is create an AWS account. Citrix C3 Lab will also be made available for public use as a set of Amazon Machine Images (AMIs) within Amazon EC2. Amazon EC2 is an on demand, utility-priced service, with charges based on the size and capacity of the virtual server.
Citrix Systems introduced an on-demand service for enterprise applications called Citrix Dazzle. For the enterprise customers already using Citrix XenApp and Citrix XenDesktop, Dazzle supports self-service IT by giving users simple access to apps and IT services in web model like the iTunes store.
Dazzle is fully integrated with Citrix Receiver, a new universal software client that makes it easy for users to access corporate apps and desktops from any device they choose. Dazzle also interfaces directly with Citrix Merchandising Server, a new head-end management system that allows for IT to actually "merchandise" apps to users, not just deliver them. With Merchandising Server, for example, administrators can set up a list of "recommended apps" in Dazzle that highlights applications they want to promote to employees - or even post "advertisements" for new or under-utilized IT applications.
Citrix Receiver allows IT organizations to deliver desktops and applications as an on-demand service to any device in any location. Following an initial download and installation, Receiver sits quietly in the background and "listens" for signals from the corporate "delivery center". This allows IT to deliver any app or desktop from Citrix Delivery Center head-end controllers like Citrix XenApp and Citrix XenDesktop, to any device with a Receiver installed. Should employees want to access their work environment from a home PC or Mac laptop, they simply go to a URL given to them by IT and download a Receiver for that device as well. As long as Citrix Receiver is installed on a device, IT has complete control over security, performance, and user experience, allowing them to deliver IT services on-demand.
Receiver is an enhanced display agent for applications hosted on backend servers.
Under the hood, Citrix Receiver is a lightweight universal software client with an extensible browser-like "plug-in" architecture. Receiver comes standard with a variety of plug-ins that communicate with head-end infrastructure in the Citrix Delivery Center product family such as XenApp, XenDesktop, Citrix Access Gateway and Branch Repeater. These plug-ins support functionality such as online and off-line app usage, virtual desktop delivery, secure access control, password management, app acceleration, multimedia acceleration, service-level monitoring and voice communications.
Citrix Receiver is free and is available immediately for PCs, laptops, netbooks and thin clients. Citrix Receiver for Apple's iPhone is also available immediately as a free download from the Apple App Store. Citrix told Linux Gazette that it is partnering with Open Kernel Labs to extend reciever to other smart phones and their first effort will be phones based on the Android mobile Linux operating system.
Citrix Merchandising Server is also available at no charge. Both Receiver and Merchandising Server require infrastructure products from the Citrix Delivery Center product family to complete their operations.

Ben is the Editor-in-Chief for Linux Gazette and a member of The Answer Gang.
Ben was born in Moscow, Russia in 1962. He became interested in electricity at the tender age of six, promptly demonstrated it by sticking a fork into a socket and starting a fire, and has been falling down technological mineshafts ever since. He has been working with computers since the Elder Days, when they had to be built by soldering parts onto printed circuit boards and programs had to fit into 4k of memory (the recurring nightmares have almost faded, actually.)
His subsequent experiences include creating software in more than two dozen languages, network and database maintenance during the approach of a hurricane, writing articles for publications ranging from sailing magazines to technological journals, and teaching on a variety of topics ranging from Soviet weaponry and IBM hardware repair to Solaris and Linux administration, engineering, and programming. He also has the distinction of setting up the first Linux-based public access network in St. Georges, Bermuda as well as one of the first large-scale Linux-based mail servers in St. Thomas, USVI.
After a seven-year Atlantic/Caribbean cruise under sail and passages up and down the East coast of the US, he is currently anchored in northern Florida. His consulting business presents him with a variety of challenges such as teaching professional advancement courses for Sun Microsystems and providing Open Source solutions for local companies.
His current set of hobbies includes flying, yoga, martial arts,
motorcycles, writing, Roman history, and
with his Ubuntu-based home network, in which he is ably assisted by his wife and son;
his Palm Pilot is crammed full of alarms, many of which contain exclamation
He has been working with Linux since 1997, and credits it with his complete loss of interest in waging nuclear warfare on parts of the Pacific Northwest.
Kat likes to tell people she's one of the youngest people to have learned to program using punchcards on a mainframe (back in '83); but the truth is that since then, despite many hours in front of various computer screens, she's a computer user rather than a computer programmer.
Her transition away from other OSes started with the design of a massively multilingual wedding invitation.
When away from the keyboard, her hands have been found wielding of knitting needles, various pens, henna, red-hot welding tools, upholsterer's shears, and a pneumatic scaler. More often these days, she's occupied with managing her latest project.
