Java developers get .Net data link
Tuesday, September 29, 2009Java developers can more easily link Microsoft .Net-based data through an interoperability bridge offered by France-based Noelios, Microsoft and Noelios said on Monday.
The bridge is known as the Restlet Extension for ADO.Net Services and is featured as part of Noelios's Restlet 2.0 M5 open source framework. The bridge leverages Microsoft's ADO.Net Data Services, for building and consuming data services from the Web.
"It's really a simple way to connect a Java application to a .Net application" using REST technologies, said Jean-Christophe Cimetiere, senior technical evangelist at Microsoft, in an interview.
"For those who are relatively new to ADO.NET Data Services, it is a set of recently added .Net Framework features that provides a simple way to expose a wide range of data sources such as relational databases, XML files, and so on through a RESTful service interface," Cimitiere explained in a blog entry. Microsoft Visual Studio 2008 Service Pack 1 and the planned Visual Studio 2010 software development platform support ADO.Net Data Services.
"So far, beside client toolkits for Microsoft technologies such as .Net and Silverlight, only the PHP language had an easy solution to interact with those services. Today, with the release of Restlet 2.0 M5, we are proud to announce a similar offer for Java developers, cleanly leveraging the Restlet Framework," said Jerome Louvel, of Noelios, in a blog. The technology is accessible at Restlet's Web page.
The Restlet Extension for ADO.Net Data Services provides a client API to extend the Restlet Framework core capability by providing remote access to data services hosted on ASP.Net servers on the Windows Azure cloud platform, Cimetiere said. The extension is not limited to working just with Azure, though, he said.
Java developers use the extension's code generator to create Java classes that correspond to data entities exposed through ADO.Net Data Services," he said. "The Java application is then able to accesses the data via a simple method call. The runtime components in the Restlet engine and the extension take care of the communication between the Java client application and ADO.Net Data Services."
Java developers using the Restlet Extension for ADO.Net Data Services can connect applications to a .Net platform with "relative ease, which means more choices for Java developers and new opportunities for Microsoft," Cimitiere said.
He also cited several other interoperability projects to link Java to Microsoft, including Apache Stonehenge, for SOA and Web services interoperability; Azure .Net Services SDK for Java; and Eclipse Tools for Silverlight.

Augmented Reality & The Web: Present and Future Scenarios
Sunday, May 17, 2009
Augmented Reality (AR) is when virtual graphics and/or data are overlaid onto real world objects. Many of you have seen this portrayed in movies such as Minority Report and The Matrix. It still seems a bit far fetched in 2009, yet there are apps that are beginning to make it a reality. One is Wikitude, an Android mobile app that mixes location imagery with information from Wikipedia. We first noticed it back in May 2008, when it was announced as one of the winners of the Android Developer Challenge.
Wikitude is described on its website as "a mobile travel guide for the Android platform based on location-based Wikipedia and Qype content." Essentially it allows users to overlay information from Wikipedia onto a photo of a certain location, via Mobile Google Maps. It currently supports 350,000 locations by GPS or by address. Wikitude was launched at the same time as the G1 phone in October 2008 and is currently available in the Android Market. Here's a video of how it works:

Wikitude represents perhaps the first stage of what is possible with AR. Microsoft recently released a video that shows other future scenarios for AR:

Microsoft's Surface app, released in May 2007, is a pointer to this future.
There are many potential scenarios for AR. A popular one is doing your grocery shopping and checking information on your mobile phone (or AR glasses!) about price, specials, reviews, comparisons with competing products, etc. With the rise of RFID chips and technology such as that being developed by Microsoft, this type of scenario isn't too far away.
Another interesting consideration is that social software will have a big role to play in future AR apps. For example when walking down the street, you could use your mobile phone to point to a restaurant, and overlaid on a photo of the restaurant would be customer reviews, recommendations, and other relevant user generated data. (inspiration from Rafael Torres)
Let us know other apps that are doing interesting things with AR technology mixed with the Internet. And of course we'd love to hear about your favorite future AR scenarios!

Android-based Alpha 680 netbook spotted in the wild
Tuesday, May 12, 2009Android-based Alpha 680 netbook spotted in the wild
Still think an Android-based netbook is in your future? If the abysmal performance on video hasn't turned you off yet, maybe the fire-engine red paint job coupled with 90s-era carbon fiber accents will. What you see above is the first legitimate in the wild shot of Skytone's Alpha 680, and at a glance, we're marginally excited about the sizable trackpad and roomy keyboard. Oh, and the swiveling screen is a plus, too. Check the read link for a few more looks.
Wolfarm Alpha

When we got the demo, Wolfram asked us to refrain from publishing any screenshots. Today, however, the Berkman Center posted a video of the public demo Wolfram gave earlier this week, so we think it's only fair that we share our own screenshots with our readers at this point.
