You may have noticed a new item in the "Get Involved" section at the upper left of the java.net home page: Java.net Enhancements . This is a new feature that's been added as a way to enable the broader java.net community to identify potential enhancements to java.net that are most important.
The Java.net Future Enhancements provides many different ways of looking at enhancements that are being considered for the site. The default view briefly describes several of the proposed enhancements, and lets you vote your view of the importance of each item or add a comment. Clicking on an item's title brings you to a detail page for that proposed enhancement, where you can see the already-posted comments, or post your own comment.
The rating system for the importance of each proposed enhancement is as follows:
- 5 stars: Must have!
- 4 stars: Very useful
- 3 stars: Useful
- 2 stars: Could be useful
- 1 star: Don't care
These additional enhancement views are also available:
- List view - view a summary table of proposed enhancements, with statistics on number of views, comments, and the target schedule for implementation (if a date has been set)
- All Completed Enhancements - a summary table of enhancements that have already been completed
If you don't see an enhancement you consider important on the Java.net Future Enhancements page, you can visit the Wish List Forum or the java-net project issue list . If still don't see the enhancement you're interested in, you can enter it as a new enhancement request, and it will be given consideration by the java.net development team.
In Java Today , Kelly O'Hair provides Faster OpenJDK Build Tricks :
Here are a few tips and tricks to get faster OpenJDK builds. * RAM: RAM is cheap, if you don't have at least 2Gb RAM, go buy yourself some RAM for Xmas. ;^) * LOCAL DISK: Use local disk if at all possible, the difference in build time is significant. This mostly applies to the repository or forest you are building (and where the build output is also landing). Also, to a lesser degree, frequently accessed items like the boot jdk (ALT_BOOTDIR). Local disk is your best choice, and if possible /tmp on some systems is even better. * PARALLEL_COMPILE_JOBS=N ...

Elliotte Rusty Harold expresses his view on the news that Sun has decided to add closures to Java 7 :
They will, of course, not remove anything to make room, so Java just gets bigger and bulkier. They will also give us a half-hearted implementation that removes some interesting pieces that would make it backwards incompatible, so we're getting really aren't closures after all. Did Sun learn nothing from the generics debacle? Most tellingly, despite all the talk of openness, this seems to very much be Sun's decision. There's no proposal in the JCP, and all discussion of this seems to have purely been internal to Sun. If you aren't eating lunch in the Sun cafeteria, you don't get to chime in. Sun simply presented the decision as a fait accompli to the community. First they decided they wouldn't do closures in Java 7; then they decided they would; and now they'll decide how and when. Scala's looking more attractive by the hour.
In today's Weblogs , John Ferguson Smart presents Test-Driven Development with Legacy code - an introduction :
Test-Driven Development, or TDD, is often quoted as an essential Agile best practice, and so it is. It works wonders on green-fields projects and new code bases where you can start afresh and ensure that all your code is both easily testable and well tested. But what about legacy code? (By legacy code, I mean any code that does not have a comprehensive set of automated tests, so you might be writing legacy code as we speak). For most of us, most of the code we will ever work on will not have originally been our own work. And, unfortunately for the software industry, only a small fraction of code can really boast comprehensive unit and integration tests. How can techniques like Test-Driven Development make our work as developers more productive and less frustrating? ...
Masoud Kalali posted Architecting a system need a wide knowledge of technologies, COTS, projects, standards.... :
When we start working on a new project as an architect we are dealing basically with a set of requirement which our architecture should be able to act as a foundation for the design and implementation of those requirements in form of a software system. to let the customer fulfill its requirements in a better and more efficient way. Preparing the architecture for a software system means not only the architect to be familiar with the domain but also he should well aware of new technologies, frameworks, COTS, and standards available not only for the domain he is working on but also for the development platform which will realize the architecture into a working piece of software...

birdwatchers in mind, but it's only a special case): ...

In our current Spotlight , Terrence Barr invites us to Check out Java Card 3.0 Connected Edition: Real Java, just really flat ;-) : "Java Card 3.0 was released a couple of months ago – and the second update (version 3.0.2) is scheduled for December. If you haven’t paid much attention to Java on smart cards because you thought it’s not “real” Java – well, look again. It’s true that Java Card 2 was very limited in many ways – a testament to the kind of technology you had available on smart cards 10 years ago. There are billions of these out there today..."
