We use PubNub and it is not in the Maven central repository as of this writing, so we have been using it as as system scope dependency in our Maven pom.xml. The dependency XML looks like this: We get a Maven warning about this setting and have been ignoring it for some time. To finally [...]
An under-reported feature of Visual Studio 2012 is the ability to create Extension SDKs for Visual C++. SDK development is analogous to creating assemblies in .NET or JARs in Java and is very important for Windows 8 application development. By Jonathan Allen
Since the last bumper release back in June, the team in charge of JBoss Tools and JBoss Developer Studio have been hard at work plotting the changes for their set of Eclipse plugins. JBoss Tools 3.3 and Developer Studio 5 were a big leap, providing a sleeker look and more cohesive experience, linking to other Red Hat/JBoss-flavoured projects such as OpenShift and Forge, with JBoss Central acting as the community hub for it all. The most radical change, included this time round in this week’s beta, is the introduction of the ‘Bring Your Own Eclipse’ concept in JBoss Developer Studio, the full distribution. This allows you to install plugins provided and supported in JBoss Developer Studio in your own Eclipse installation, via Eclipse Marketplace. Project lead Max Rydahl Andersen informs us that this feature is still awaiting approval, but should it pass quality control, the boundaries of JBoss Developer Studio will be broken down. Plenty of work has gone towards the OpenShift side of the project. JBoss Tools 4 appears to have refined SSH Key management, a common stumbling block for people wanting to test out the cloud platform. The beta has also made it possible to connect to multiple OpenShift servers. Also included is JBoss Stacks, a new project (created alongside JBoss Developer Framework) aiming to make it easy to pick your stack of choice via a drag and drop functionality. From the outset, users can choose JBoss EAP 6 or JBoss AS 7.0 and 7.1 That’s just scratching the surface - check out all of what is New and Noteworthy through the beta blogpost. A note though, SOA tooling for a large number of projects (BPEL, Drools, Guvnor, jBPM, ESB, ModeShape, pi4soa, Savara, SwitchYard, Teeid) is no longer provided in JBoss Tools, and will arrive at a later date.
The results are in for the JCP 2012 elections, with the London Java Community re-elected and PaaS provider CloudBees being elected for the first time in the open vote. Following the vote, the SE/EE and ME Executive Committees will be merged into a single Executive Committee, which will start to focus on the thorny matter of IP issues. By Charles Humble
A central theme with Windows 8 is the Microsoft Account. This is another attempt to offer a single sign-on system for both Microsoft and third-party services. Microsoft Account is available for Windows 8 apps, normal websites, Windows Phone, Android, and iOS. By Jonathan Allen
Open source web-search framework Apache Nutch version 2 supports large scale crawling, link-graph database and HTML parsing. InfoQ spoke with Julien Nioche, VP of Apache Nutch project, about the framework new features and its future roadmap. By Srini Penchikala
With modern websites becoming increasingly reliant on libraries like jQuery, Bootstrap and Backbone.js, managing these components also becomes increasingly annoying. James Ward of Typesafe saw a parallel with the way Java libraries were once manually downloaded before the days of managed dependencies, and set about working on WebJars, a method for allowing the necessary JavaScript and CSS to be packaged as Jar files. “Why not do with web libraries like we now do with Java libraries and specify them as managed dependencies?” he wrote in April. “This allows us to declaratively set the version, use a consistent version across an application, and easily deal with transitive dependencies.” For example, specifying Bootstrap 2.2.1 as a dependency includes jQuery 1.8.2 automatically. While an initial experiment was released in April, yesterday Ward launched a new site for the project, webjars.org, and released these WebJars to Maven Central. The new website also includes instructions for making WebJars compatible with web frameworks such as Play 2, Spring MVC and Servlet 3. Grails instructions are promised to be “coming soon”. So far there are 31 libraries already available, including angularjs, ember.js and of course jQuery, and new frameworks can be requested as an issue on GitHub. Of course, keeping these libraries up-to-date is another story - but the open-source nature of the project should hopefully mean others can help contribute. Photo by Kim Knoch.
In this JAXconf session, Ted Neward presents a handy guide for Java developers thinking of picking up the object-oriented and functional language Scala. In this presentation, Ted focuses on going "beyond" the syntax by tackling the hardest problem of learning a new language--thinking in that new language.

With Gradle we can execute Java applications using the JavaExec task or the javaexec() method. If we want to run Java code from an external dependency we must first pull in the dependency with the Java application code. The best way to do this is to create a new dependency configuration. When we configure a task with type JavaExec we can set the classpath to the external dependency. Notice we...

The ARM TechCon keynote "Why Ultra-Low Power Computing Will Change Everything" was anything but low-powered. The speaker, Dr. Johnathan Koomey, knows his subject: he is a Consulting Professor at Stanford University, worked for more than two decades at Lawrence Berkeley National Laboratory, and has been a visiting professor at Stanford University, Yale University, and UC Berkeley's Energy and Resources Group. His current focus is creating a standard (computations per kilowatt hour) and measuring computer energy consumption over time. The trends are impressive: energy consumption has halved every 1.5 years for the last 60 years. Battery life has made roughly a 10x improvement each decade since 1960. It's these improvements that have made laptops and cell phones possible. What does the future hold? Dr. Koomey said that in the past, the race by chip manufacturers was to create the fastest computer, but the priorities have now changed. New computers are tiny, smart, connected and cheap. "You can't underestimate the importance of a shift in industry focus from raw performance to power efficiency for mobile devices," he said. There is also a confluence of trends in computing, communications, sensors, and controls. The challenge is how to reduce the power requirements for these tiny devices. Alternate sources of power that are being explored are light, heat, motion, and even blood sugar. The University of Michigan has produced a miniature sensor that harnesses solar energy and could last for years without needing to be replaced. Also, the University of Washington has created a sensor that scavenges power from existing radio and TV signals.Specific devices designed for a purpose are much more efficient than general purpose computers. With all these sensors, instead of big data, developers should focus on nano-data, personalized information that will adjust the lights in a room, a machine, a variable sign, etc.Dr. Koomey showed some examples:The Proteus Digital Health Feedback System, an ingestible sensor that transmits when a patient has taken their medicine and is powered by their stomach juices. (Gives "powered by you" a whole new meaning!) Streetline Parking Systems, that provide real-time data about available parking spaces. The information can be sent to your phone or update parking signs around the city to point to areas with available spaces. Less driving around looking for parking spaces!The BigBelly trash system that uses solar power, compacts trash, and sends a text message when it is full. This dramatically reduces the number of times a truck has to come to pick up trash, freeing up resources and slashing fuel costs. This is a classic example of the efficiency of moving "bits not atoms." But researchers are approaching the physical limits of sensors, Dr. Kommey explained. With the current rate of technology improvement, they'll reach the three-atom transistor by 2041. Once they hit that wall, it will force a revolution they way we do computing. But wait, researchers at Purdue University and the University of New South Wales are both working on a reliable one-atom transistors! Other researchers are working on "approximate computing" that will reduce computing requirements drastically. So it's unclear where the wall actually is. In the meantime, as Dr. Koomey promised, ultra-low power computing will change everything.
