Java kills the cable box?

One of the early "stories" used to promote Java was about how its run-anywhere nature would be great for all manner of devices, not just desktop computers, servers, or (a little later) phones. We're seeing evidence of this promise coming true in the set-top box realm, with the Blu-Ray Disc Java standard, and various interactive TV standards such as Multimedia Home Platform (MHP) and GEM (Globally Executable MHP) for the interactive TV set-top box.

Now Java stands poised to eliminate the set-top box altogether, by becoming an interactive TV platform that manufacturers include in the television itself.

PC Magazine reports on a major win for Java-based interactive TV in Sony to Build 'Tru2way' Interactive TVs

Cable companies and the consumer electronics industry came one step closer to reaching a deal on "plug and play" TVs Tuesday when six of the nation's largest cable companies and Sony Electronics agreed to a standard that will allow consumers to access interactive digital and high-definition video without the assistance of a set-top cable box. Sony and the cable companies – Comcast, Time Warner Cable, Cox, Charter, Cablevision and Bright House Networks – agreed to adopt: the Java-based "tru2way" solution powered by CableLabs; new streamlined technology licenses; and new ways for all those involved to cooperate in the development of tru2way technology at CableLabs, according to Sony and the National Cable & Telecommunications Association (NCTA).

And there's a java.net link here too. "tru2way" is the customer-facing name for services running atop the OpenCable Platform, which exists as a Mobile & Embedded Community project on java.net.

So how real is this stuff? Real enough for another manufacturer to show off prototypes:

Samsung Electronics announced support for the tru2way technology earlier this month at The Cable Show in New Orleans, where the company showed off the SMT-3090l, a dual-tuner tru2way HD DVR, as well as a set-top box and an LCD TV.

This is great news for the OpenCable folks, for Java, and for consumers, who'll eventually be able to buy whatever TV they like and be able to plug it directly into modern cable systems and get interactivity and electronic program guides... to say nothing of future tru2way devices and features, such as DVR functionality.

Kirill Grouchnikov continues his series of interviews with top Java GUI developers by talking to the creator of in MiG Layout in Swing, RIA and JavaFX - interview with Mikael Grev. Mikael talks about his day job as a fighter pilot instructor with the Swedish Air Force, how Swing compares to competing GUI toolkits, his feelings about and plans for JavaFX, and whether Swing should be considered a premier choice for cross-platform application development. Also check out Kirill's interviews with Amy Fowler and David Qiao.

The latest JavaOne Community Corner Podcast is

j1-2k8-mtT06: Wonderland with Kids.
"This presentation relates to the World Wide Volunteer Week 2008 Project named "Hello Buddy/Hola Amigo" organized by Gilda and Juan Carlos. The main goal in WWVW project is bridging the digital divide among children by improving their second language. In this particular project, two primary schools, one located in the Bay Area in California and another in Santiago Chile, will be connected via Wonderland, a virtual space developed at Sun Microsystems Laboratories. By using the resources provided by this virtual space, children will communicate with their buddies and practice their second language. Gilda Garreton in the Bay Area and Juan Carlos Herrera in Sun Chile are driving this project."


In today's Weblogs, James Gosling says
Happy Birthday, Ivan!
"I spent the afternoon at the Computer History Museum at an event celebrating the 70th birthday of Ivan Sutherland. He's famous for a whole lot of things, the earliest being Sketchpad, a man-machine graphical communication system that he built in 1962."

Rémi Forax argues that
Parameterized type are NOT inherently unsafe.
"Time to time, i heard that sentence "array of generics a inherently unsafe". That not true, I would like to explain why and propose to change the Java Language Specification to reduce the pain to use array of parametrerized type."

Finally, Eamonn McManus continues his JavaOne retrospective series in
JavaOne report: Concurrency.
"This is the third installment in my summary of the sessions I attended at JavaOne this year. This one covers concurrency. Capsule summary: Fork/join; data races; transactional memory..."


In today's Forums,
David Grace offers his strategy for 3d graphics APIs in Java, in
RE: petition for java3d in the next java release.
"The whole point of Java is that it is platform independent. This is far easier to achieve if you are not directly coding to an OS specific library. For 2D graphics Java2D is written on top of OpenGL and DirectX (etc) and then everything 2D is written on top of Java2D. The same should be true for 3D graphics. There should be a Java layer (Java3D) written on top on OpenGL and DirectX and then everything 3D is written on top of Java3D. It really is that simple. Any other long term solution for Java is crazy."

Hinkmond Wong is collecting helpful information for putting Java on jail-broken iPhones, in
Re: Porting to iPhone.
"I've starting a TWiki page at: http://wiki.java.net/bin/view/Mobileandembedded/PhoneMEAdvancedPlatformsIPhone. Please let me know if you are able to do step #0-3 (steps I've added so far). You have already performed step #2, so you can skip that. Once you have completed up to step #3, let me know and I will send more instructions that you can help test out before I transfer to the TWiki page."

mthornton addresses the genericizing of primitives, in
Re: No Primitives in java Collection (boxing / unboxing)
Yes it would be nice if generics was extended to primitives. However, for consistency, we first need to reify generics (i.e. add classes which do not erase their type parameters). It is quite a bit of work and currently appears to have low priority. I have checked out the OpenJDK compiler and have started hacking a change, but currently have very limited spare time (too much real work to do).
