Connect Your Phone With Any Other Devices with JXTA

Two exiting news about JXTA :-)  First, the JXTA community just released an enhanced JXTA bidding (jxta-jxme 2.5) for J2ME MIP2.0.  If you want to learn more about the new JXTA MIDP 2.0 implementation and check how to connect your phone with a PC and  printer, check Mohamed's video.  Second, Bondolo just announced the availability of a Grizzly NIO patch for the JXTA Java SE binding that is going to drastically reduce thread resource consumption when JXTA peers accept incoming HTTP connections. Great to see another collaboration between the JXTA and Glassfish(Grizzly) open-source community.

Project SAXTA: An Eco-Friendly Distribution Network to View Earth Data

    Project SAXTA (the acronym SAXTA is derived from SAtellite JXTA) is a new, open network dedicated to the sharing of high-resolution NASA Earth observation data sets such as Landsat and ASTER data. SAXTA is using a decentralized JXTA P2P network architecture that enables users, Earth science scientists, and educators all over the world to freely access and share Earth data without requiring NASA to host a massive centralized infrastructure to serve content.  SAXTA architecture really paves the way for a new generation of eco-friendly distribution network that will help reduce CO2 emissions. When looking for a content, the SAXTA network can determine the closest path to a copy of the content to reduce the number of hops packets have to go through and to minimize overall packet processing and traffic.  MSN and Google's Earth may want to take a closer look at what NASA and the SAXTA folks are doing.

To join the SAXTA network click here.

As a side note,  the same eco-friendly JXTA technology used by SAXTA is also powering Sun's Glassfish appserver clustering product :-)

The Network is You: It was Just a Matter of Time!

Interesting comment from Rob Graham from iMediaConnectionThere are plenty of creative people all around the world who now have access to media development tools never before available. They have direct access to new broadcast channels never before available.  It's only a matter of time before these upstarts sets the traditional television, movie, music, radio broadcast world on their ears.”

Well a couple week ago, RadioHead dropped a bombshell on the music industry announcing their new album “In Rainbows” will be released directly from their official web site.  Even more interesting, people can download the album for any price they want to pay, including free :-)

From The Seminal, "In Rainbows sold approximately 1.2 million copies as of October 12th.  In comparison, that’s more albums sold in the first week than Radioheads’ last three releases combined.  According to an Internet poll of 3,000 people, the average price paid for In Rainbows was $8.  If these numbers are accurate, Radiohead has made close to $10 million in one week on this album alone."

Amazing, well this may just be the beginning :-) I was just reading that over the next 3 years it is expected that more content is going to be generated than over the last 40,000 years of mankind existence! (from UC Berkeley School of Information Management)

Even more interesting, with upcoming 20mbps symmetrical broadband connection and low-cost Terabytes storage appliances everyone will soon be able to distribute and monetize content from their own home. So, should we care if the content is viewed from an iPhone, gPhone or mPhone?  The Network is You!

Finding what people are doing with your open-source technology? The JXTA Example

One of the minor drawback of open-source technologies, like JXTA,  is that people don't have to tell you when they are using open-source technology. Unless they file a bug, contribute patches, or you run by hazard on their project pages or mailing archives, you may never find what people are doing. Here is my latest list of projects using the JXTA technology, which of course, I never heard of before:

 - ActiveMQ

- Eclipse Communication Framework

- Slide


-Semantic HIFI


By the way if you are looking for an internship working on JXTA, I just ran into this.

While you wish everyone will contribute back to your open-source project, the fact that people are using your technology, without you knowing it, is a good sign you created a successful open-source project :-)

Glassfish, Shoal, JXTA: What's in Common?

From the Aquarium, Eduardo is mentioning the positive review from TheServerSide of the latest Glassfish V2 M4 build. The article points to the new Glassfish improvements in the dynamic clustering and HA features that are using Project Shoal and the JXTA technology. Great to see three open-source projects (Glassfish, Shoal, JXTA) working and leveraging each other.  A great example of how open-source development should work.

VamPeer: New Eiffel Binding for Jxta

Another great contribution from Beat Strasser from ETZH to add a Eiffel binding for Jxta. This goes along with Scala, Groovy and Tuscany adoption of the Jxta technology. It is great to see student contributions to the core Jxta technology. Beat, congratulations on your Master :-)

Scala + JXTA = Seamless Functional Web 2.0 Service Mashup

Interesting combination of Scala and JXTA to implement seamless network mashup of Web 2.0 functional Scala actors. It certainly makes a lot of sense to use JXTA's virtual pipes to simplify the network stack to connect Scala remote actors. Another adoption of the JXTA technology which goes along what was proposed for Groovy

Beyond the RESTfull vs RESTless argument, here comes P2P/JXTA Web Service Mashup!

Another endorsement of the JXTA technology by the Apache's Tuscany project to mashup and federate Web 2.0 services. This adds to this week annoucement from Samooha to open-source their JXTA-based P2P SOA Enterprise stack.  Beyond the RESTfull/RESTless argument, these projects look to provide a more decentralized and ad hoc way to mashup Web services. This will  likely help ease Web services deployment, management and discovery. A couple years ago I worked on a WS-Name Service proposal to build a decentralized name service for Web services (the equivalent of DNS for Web services) that was using JXTA to enable dynamic mashup of Web services.  After the recent annoucement of Project Shoal using JXTA, the JXTA technology is really picking up steam in the Web 2.0 service delivery arena :-)

Why We Need A "P2P Eco-Friendly" Internet?

One thing which attracted me to P2P (and to work on JXTA) was that I always thought the Internet will reach a metldown point due to the way information distribution is currently over centralized. Well:  In 2005 it took the equivalent of 14, 1,000-megawatt power plants to keep online the world's data centers owned by Internet giants like Google (GOOG), Microsoft (MSFT) and Yahoo (YHOO). And that's not counting YouTube! As a simple analogy, do we really need everyone PCs to connect to the Yahoo site to read today Yahoo headline news, or can we realize that a PC, next to the cubicle the person is seating, or somewhere in the building, or the city, already has a copy of the article!

If you truly want to save the planet!  It's not too late. Just check :-)

Information or Disinformation: P2P traffic 60% of the Internet Traffic?

Interesting article. While we should give credit to Bittorent and other P2P applications, I am not convinced this statistics is right (in the first place how do you measure such broad traffic percentage, are we truly accounting for all available cross-bandwidth  between all edge peers in the Internet, or just cross-traffic bandwidth between a few main Internet infrastructure routers). Looking at the success of YouTube, Metacafe, etc.. I have the hitch that still most of the Internet overall traffics is coming from centralized download services that are creating even greater traffic and bottlenecks  :-)

The Jxta community is getting ready to announce the JXTA-Java SE 2.5 Beta release. It's a must release if you are a serious
JXTA developers.

Groovy + JXTA: How to make life simpler for P2P developers!

In the pure spirit of open-source development, the Groovy and JXTA communities are looking to join force to ease the development of p2p applications. For more check the following thread and feel free to jump in and join the effort. This can only be good for Groovy, JXTA and P2P developers :-)
