Gosling on OS Java

Posted by daniel on April 30, 2004 at 9:54 AM PDT

"If we do something to make Java even more open-source than it is already, having safeguards to protect the developer community will be something we pay a lot of attention to."

In today's Weblogs , James Gosling blogs about Open sourcing Java . He addresses IBM's open letters and their history of contributing to Java. One interesting point is the Swing/SWT/AWT issue. Gosling notes that "IBM was the major mover that led to the creation of the Swing API to replace the AWT api. They contributed many engineers to the Swing team. Viewing that time in hindsight, it is more than slightly ironic that these days they're endorsing SWT, which is essentially a clone of the AWT architecture, which they had strongly condemmed back when the decision to create Swing was being debated."

Every time we have had a conversation about open sourcing Java here on java.net, the feedback has been fairly balanced. There are folks on both sides of the open source issue for whom it is a religious matter. There are others who express their concerns with IBM and others about what could happen to the platform. Gosling summarizes these folks as being "afraid that if Java is open-sourced then someone will try to fragment the community by creating incompatible versions of Java and ignore the community process, just like Microsoft did. Microsoft did a lot of damage to the community and many developers strongly do not want that to happen again." As the quote at the top shows, this is front and center in Sun's mind.

Users who sign up for one flavor of instant messaging still want to be able to chat with friends who have signed up with another. In Anti-Social Software Brendon J. Wilson notes that "
Social networking systems have followed a similar path, coding users into the very same corner[...] Social networking systems are pathologically anti-social on three fronts: their lack of functionality, lack of a web services API, and lack of federation."

Rory Winston questions whether insulating developers from the dataebase layer is always a good idea in O/R Mapping and Performance. He presents three instances of performance impact that developers should be aware of: Improperly configured or non-existant lazy initialization, the inability to use database-specific optimizations, and cache configuration.

Also in Java Today
, JSR 175 introduces metadata to the Java programming language. In "Declarative
Programming in Java
" Narayanan Jayaratchagan says that "Every new release of Java has introduced new features, but few warrant a new way of thinking to realize their full potential. Using annotations effectively to simplify programming in Java requires a shift in our thought processes. Even though we use declarative programming languages such as SQL and XSLT most frequently, it may take some time for us to understand how to use declarative and imperative
programming together."

Vikram Goyal moderates the first discussion in our new forum The Programming Profession. He kicks off tips to technical interviewing with an article titled So you don't know what a static inner class is? Think back to your experiences on either side of the interview process and chime in.


In Forums today, John Mitchell asks Architecture? What architecture? He asks "Is it true that the vast majority of systems have no coherent architecture?

Is Brooks' definition of architecture really just another way of talking about end-user usability / interaction design? What about the interface between the different facets and components of the system?"

Is there a mismatch between what your developers can do and what you are asking them to do? rickcarson suggests that the problem may not be one of available skills. In Bargain Developers he writes "about a kid in the US who was failing maths. But when they asked him about baseball, he could rattle off all sorts of university level statistics about it... and the kid is like 8 or 10 yrs old. He's not stupid, its just that he finds maths boring, and baseball interesting". His moral is that "If you want to change the low productivity programmers into high productivity, find what they like and are good at, and get them doing that".


In today's Projects and Communities , the Java Desktop community tip of the week features a site that "points to a bunch of nice web tools for choosing color schemes. [O]ne even shows you how the colors look to people with various kinds of color blindness! "

The JavaOne Wiki page is intended as a way to let people know about java.net community members who are doing presentations at JavaOne. Add your talks and create pages to arrange meetings while at the conference.
