Dolphins respond to bugs
Contributing bugs and ideas
Yesterday's MySQL conference kicked off with a State of the Dolphin address by David Axmark and Michael "Monty" Widenius. One of the reason's for MySQLs success are the contributions from the community. They noted that contributed code often does not make it into the source tree but that the ideas behind the contributed code often does.
They advised the conference attendees that the most valuable contribution they could make would be to file bugs with code that demonstrates the problem. They said that MySQL has a history of responding to these bugs and fixing them because it encourages others to find and submit bugs. This cycle is what leads to a more robust product. If they don't respond to the bugs in a timely way, people will stop taking the time to file the bugs and everybody loses.
The end of a forum post today reminded me of this cycle at its best.
Kohsuke posts about A better tool integration API for XJC
in today's Forums.
"the JAXB RI 2.0 EA includes an improved tool integration API for jaxb
workshop. Take a look at
public static int Driver.run(String args, XJCListener listener)and com.sun.tools.xjc.XJCListener. Most of the errors are reported as
SAXParseException. Based on an early feedback from Kirill, I modified it and added a new callback to report a file generated from XJC."
It's that last sentence that stands out for me. Changes were made because of feedback. Keep sending in your bugs and ideas. It looks as if people are listening.
Trembovetski follows up on the resolution of another longstanding bug The Swing's Gray Rect fix. "A fix for a very important and old swing bug has been integrated in the latest mustang snapshot (b32). The dreaded gray rect is now gone!

Eduardo Pelegri-Llopart points you to the Revamped JWSDP Developer home page
in today's href="http://weblogs.java.net"> Weblogs . "There has been a lot of new activity in the JWSDP community including new EAs for JAX-RPC 2.0 and JAXB 2.0; the SJSXP and JAXP 1.3 weekly builds."
Vincent Brabant thinks Wink is Great. He says Wink is " a Tutorial and Presentation creation software. That tool is great and very powerfull. You can in somes minutes create nice presentations."
Is there a need for Remedial Programming Classes? John Reynolds worries that " U.S. students earlier this month made their worst showing in the 29-year history of the ACM International Collegiate Programming Contest. " He passes on a story that "many universities are actively shunning relevancy in their computer science curriculums (they don't want to be confused with vocational schools)."
In Also in
Java Today , Cedric Buest blogs on The perils of duck typing . With some languages if you have a method that takes a parameter of a particular type and calls methods on that object, it is only important that the object knows how to respond to those methods and not that the object is, in fact, of the type specified. He says that "Duck Typing is a big time saver when you write code, but is it worth it? Don't you pay this ease of development much later in the development cycle? Isn't there a risk that you might be shipping code that is broken?" And answers that "the answer is obviously yes." His example comes from Ruby and he explains why he thinks there may be problems.
The scripting crowd is justly proud of the support for regular expressions in languages like Perl, but Java has had an equally powerful regex engine since Java 1.4. In Regular Expressions in J2SE, an ONJava reprise from 2003, Hetal C. Shah introduces regular expression concepts, and how to create Patterns and Matchers to find and replace matching pieces of text.
In Projects and
Communities, the Linux Java community points to an article from LWN.net about version 4.0 of GCJ (the GNU Compiler for the Java Language), saying that when combined with projects like JPackage, it will deliver a F/OSS platform for Java projects, compatible with the restrictions of F/OSS Linux distros.
The Java Tools community's latest newsletter is heralding the graduation of four HTML related tools: HTMLStrings, HTMLURLs, HTMLEntities, and HTMLColors. Each contains a collection of static methods to manipulate and convert to and from HTML standards.
