Conferences, JUG Meetings, Seminars, etc.

Dustin Marx considered How Much Time to Spend on JavaFX at JavaOne 2010?

For any conference that one attends, one of the difficult decisions is which presentations to attend. This is particularly problematic when there are some really interesting-sounding presentations held during the same hour. I find that I often change my plans for which presentations to see based on earlier presentations in the same conference. A presentation (often an opening keynote) may stir my interest in a topic I had entered the conference not knowing or not caring much about. On the other hand, an early presentation could equally dissuade me from attending further presentations on the same topic because I may realize that the subject is not as relevant to me as I thought it would be. I am already struggling with this for JavaOne 2010, particularly when it comes to JavaFX presentations...

Dustin also posted a lament, JavaOne 2010: So Many Interesting Sessions, So Few Time Slots-

JavaOne 2010 has so many presentations that I want to see that even my current alternatives list ("My Interests" in Schedule Builder) is full of presentations that sound compelling. The following presentations are currently in "My Interests" because I have (as of today) selected another presentation at the same time to "Enroll" in. I think this list speaks for itself. Of course, it is likely that I will change my mind several times between now and JavaOne and it's almost certain that I'll attend some of these. For now, though, these are the presentations I wish I could attend, but currently think I'll have to miss because there's something else also scheduled at the same time...

Eduardo Pelegri-Llopart provided JavaOne News Update 1:

An update on some recent News on JavaOne 2010. As you know JavaOne San Francisco is Sep 19-23, 2010. TheOfficial page has links to the Registration Page and the Online Catalog. News updates include: • A surprisingly useful & manageable Catalog-as-tweets via @javaoneconf; • Availability of Schedule Builder (post); • Open enrollment in Java University (post)...

James Gosling was Hanging out at SIGGRAPH:

I'm spending this week hanging out at my favorite Geek+Artist Fest: SIGGRAPH. The folks from Weta did a great presentation today on the work they did on Avatar. Between their fascinating simulation of muscle dynamics for accurate skin deformations, the many ways they used deep alpha maps & abused the immense size of their disk farm, to the studly tricks they did with spherical harmonics to fake out global illumination...

Alexis Moussine-Pouchkine got Back from FISL:

So I'm back from FISL and I have to say I wasn't disappointed. For people that have attended both FISL and OSCON these two conferences seem to have a lot in common. FISL had somewhere between 4000 and 5000 attendees interested in many different OSS topics which means it's quite different from your typical Java conference (lots of python, multimedia, security, linux desktops, etc.)...

Arun Gupta posted his FISL 2010 Trip Report:

4998 attendees registered and participated at the 11th edition of FISL - the biggest open source conference in Brazil. This was my second year at FISL. Even though the attendance was slightly down from last year but there was no let down in the energy. With 13 parallel tracks and sessions running from 9am to 11pm, it can be absolutely overwhelming. However most of the sessions were in Portuguese (with no English translation) so I could not attend. I presented on the Java EE 6 Toolshow to an audience of approx 200...

The JavaOne Conference Blog announced that JavaOne Early Bird Ends July 30! Really:

YGTBHA: You're Going to Be Here Anyway. You want to see and learn about the newest products and meet experts and business leaders. You want to save money and get a big discount for registering early. You only have one more day before the extended early bird deadline runs out on July 30. It's only logical. Do it. Last chance for the early bird discount. Really. Register Now!

I passed on the news about the Oracle Video Challenge: an Opportunity to Attend JavaOne for Free!

The Oracle Video Challenge, which started yesterday and runs through August 9, will provide three winning contestants with a free Oracle OpenWorld or JavaOne and Oracle Develop full conference pass...

Remi Forax posted JVM Summit'10:

JVM Summit'10 presentations are already available.

JavaEE, GlassFish

Alexis Moussine-Pouchkine discussed Module initialization order in Java EE 6:

One of the new features in the umbrella Java EE 6 specificationis the ability to define the order in which modules (web applications for instance) from a given Java EE application are initialized by the container. This might be useful if you want for example a given module to serve as resource initializer to create a database table before any other module can be accessed (note this does not apply to application client modules). Previously, the order in which Java EE application modules were initialized...

Alexis also talked about Servlet 3.0, fragments and web.xml to rule them all:

Servlet 3.0 has some very nice ease-of-development features in the form of new annotations (such as@WebServlet) and some useful extensibility features with web-fragments (details here) and ServletContainerInitializer which all contribute to make web.xml optional. While this is a great step towards more modular applications and an overall development simplification, you may want to have more control over what's being deployed in your production system. This is whatmetadata-complete helps you achieve...

Eduardo Pelegri-Llopart talked about Closed Networks and the GlassFish Update Center:

One of the best features about all the versionsof GlassFish 3 is how easy it is to update it through the IPS-basedUpdate Center. The same GUI and CLI toolscan be used to upgrade from 3.0 to 3.0.1, to Addor Remove components and to switch from the Open Source to the Oracle's Commercial release...

Arun Gupta provided QA#4: Java EE 6: Developers focus on business logic, Much lower TCO - by Johan Vos:

Jigsaw puzzle, modular, standard, integrated specifications, simple, annotation-driven, standards compliance, vendor independence, and light-weight deploymentare some of the benefits highlighted by the Java EE 6 community...

Bhakti Mehta talked about Deploying webservices on Glassfish 3.1 cluster:

The following blog shows how to deploy webservices on a 2 instance cluster using glassfish 3.1 .

Tools, IDEs, etc.

Andrew Bayer discussed Continuous Deployment, Code Review and Pre-Tested Commits on Digg4:

One of the exciting things, from a development perspective, about Digg4 is continuous deployment - when developers fix a bug or add a new feature, there's no need to wait for a scheduled release. Instead, the change can go live right away. This is great - the turnaround time for a change drops dramatically. But this also opens up the possibility of broken changes going live, since there won't be manual testing and signoffs before the changes go live. Figuring out how to balance the speed and agility of continuous deployment with the requirements for stability and reliability has been, and continues to be, a major challenge for us here...

Geertjan Wielenga was working on Extending IntelliJ IDEA for NetBeans Platform Development:

My article Using IntelliJ IDEA for NetBeans Platform Development is still valid and provides a viable approach to creating NetBeans Platform applications in IntelliJ IDEA. However, this would obviously be a lot better...

Geertjan also offered the IntelliJ team Thanks for Open Sourcing IntelliJ IDEA:

Thanks for Open Sourcing IntelliJ IDEA. It's come in really handy now that I'm creating facets for the NetBeans Platform and NetBeans modules (at some point, for OSGi bundles too, I think). Here you can learn how to create Facets, simply by reading the facet for Groovy. Without the Groovy facet, I would have been totally lost...

Hudson Labs announced Hudson 1.368 Released!

Regular readers will recognize that I've been slacking off quite a bit lately with my release announcements, my apologies. With the release of 1.368 on Sunday, which fixed a few fairly important bugs, I figured I'd dusty off my blogging fedora and give this a shot. This release has three bug fixes in it which were causing some issues for some users, particularly those deploying Hudson inside the recently released Tomcat 7.0 (see issue 6738)...

Fabrizio Giudici posted Maven is good, but needs some love:

You know that I've moved to Maven more than one year ago and I don't regret. I think I would be unable to manage the number of projects I'm managing on my own without it (or at least without an effective artifact repository). But Maven needs a proper and clean environment. Maven experts are constantly advising about that. One of the most important pieces of the environment is the artifact...

This week's new java.net Spotlight is JFrog's To Build or Not to Be - Seminar Videos:

JFrog's Continuous Integration and Build Seminar "To Build or Not to Be", took place on July 1st, 2010 and was a big success.

Jan Haderka announced that SwingX 1.6.1 is in central maven repo:

As Karl mentioned already in his blog, SwingX 1.6.1 was released few weeks ago. There were some issues uploading the artifacts to central repo this time, due to previous nexus migration and changes in structure of repositories, but all is solved now. To use 1.6.1 simply update your pom to...

Jan also announced SwingX going Maven ... maybe:

I've just committed mavenized version of swingx under the swingx-r3734-mavenized branch. If you know nothing about maven here's the basic: download and install (unzip) maven from http://maven.apache.org you should not need to configure anything apart from geting maven/bin on your path so you can run maven to build swingx you need to run "mvn install" or ...

JDK, JVM, JSRs

Last week's java.net Spotlight was the Oracle Technology Network's latest TechCast Live: Toward a Universal VM, Episode 11:

TechCast host Justin Kestelyn interviewsOracle's Alex Buckley, who explains why the JVM has been good not only for Java, but also for other languages -- and why JSR 292 will have a major impact on developers.

This past week's java.net poll asked What impact do you expect JSR 292 (invokedynamic) to have long term? A total of 239 votes were cast, with the following results:

  • 26% (62 votes) - Enormous: it provides critical functionality we've needed for a long time
  • 30% (71 votes) - It's an important, but not earth-shattering, enhancement
  • 18% (44 votes) - Let's wait and see
  • 7% (16 votes) - Minimal
  • 18% (43 votes) - I don't know
  • 1% (3 votes) - Other

Programming

On DeveloperWorks, Ted Neward highlighted 5 things you didn't know about ... the Java Scripting API:

Many Java developers today are interested in using scripting languages on the Java platform, but using a dynamic language that has been compiled into Java bytecode isn't always possible. In some cases, it's quicker and more efficient to simply script parts of a Java application or to call the particular Java objects you need from within a script...

Mobile

Terrence Barr reported Just in: Unlocking and jailbraking phones now legal in the U.S.:

This decision just in: The U.S. Library of Congress, which oversees the Copyright Office, has just announced new rules that effectively legitimize unlocking and jailbreaking of phones. This is significant, because the ruling states that owners of phones actually do own the phone, rather than just being a licensee of the manufacturer, and thus are allowed to circumvent controls that the manufacturer put in place to limit what is considered fair use of the device.

Shai Almog was Sliding It Back To My First Post in his latest LWUIT post:

My very first post in this blog (May 2008) was about creating a progress indicator component. At the time LWUIT only had one style per component and the post was mostly about threading in LWUIT. Over that time we considered adding a progress indicator component frequently but had a very difficult issue with its customization. How can we create a component which is both powerful enough for general usage and not too restricted for the various use cases...

Open Source Projects

Kirill Grouchnikov published Release candidates for Trident, Flamingo and Substance:

I’ve just published the release candidates for the following projects: * Trident 1.3 (code-named Diamond In The Sky); * Flamingo 5.0 (code-named Imogene); * Substance 6.1 (code-named Trinidad); * Substance Flamingo plugin 6.1 ...

Java.net's Cajo Projectannounced the latest cajo SDK release:

The cajo project has released a small (110kB) SDK for developing distributed Java RIAs quickly and easily. The SDK handles the display and distribution tasks behind the scenes, with virtually no source impact. Ordinary Swing user interfaces are rendered full-frame in browsers as Applets, and via WebStart, automatically. Application objects can be distributed transparently over multiple JVMs to improve performance, reliability, and scalability.

Miscellaneous

This week's new java.net poll, which was suggested by Eduardo Pelegri-Llopart, is intended to assist java.net with future planning. The poll asks Which of the following describes your java.net user account(s) and account-related email addresses? The poll will be open for the next week.

We have two other JavaOne conferences scheduled: December 7 - 9, 2010 in Brazil and on December 13 - 16, 2010 in China. Those conferences will be similar to JavaOne in San Francisco...

Dustin Marx noted that the JavaOne 2010 Schedule Builder is Now Available:

I previously posted that I was looking forward to JavaOne 2010 and this is even more true today.  Like Mitch Pronschinske, the trouble now is determining which presentations to attend.  This "problem" is complicated by the coexistence of Oracle OpenWorldand Oracle Develop with JavaOne 2010.  There are roughly 2400 different options for sessions, conferences, keynotes, Birds of a Feather (BOF) sessions, and so forth between the three simultaneous conferences...

The goal of the petition is to increase the viability of the JavaFX platform to the benefit of both the community and Oracle. To the Leaders, Management, and Board of Directors at Oracle Corporation, We the undersigned formally request that Oracle Corporation release the entire JavaFX Platform as open source software available for modification and reuse by individuals, educators, and corporations...

Shai Almog conducted a poll in conjuction with his latest post,How Can Oracle Make JavaFX More Popular?

The guys at the JavaLobby asked "How Can Oracle Make JavaFX More Popular?", however the discussion seems to be hopelessly slanted towards the desktop crowd and a couple of Android related posts. I'm quite curious to see what the thoughts of the crowd visiting this blog which mostly focuses on mobile and LWUIT. So I added a poll to the top of the blog...

Dustin Marx talked about The Continuing Struggles of JavaFX:

In the post O JavaFX, What Art Thou? I publicly posted questions about JavaFX that largely pertain to its future.  As I stated in that post, I had felt somewhat deceived by Sun's overhasty JavaFXmarketing at 2007 JavaOneand 2008 JavaOneand wasted more time than I like to waste looking into what JavaFX was (or in most cases, was supposed to become).  I have hesitated to really invest time and effort into it a third time until I feel better about its future.  Since posting O JavaFX,What Art Thou? there's been little to make me feel more optimistic about JavaFX's future.  This week, there was a major piece of bad press for JavaFX. In his blog post JavaFX is a Train Wreck, Kirill Grouchnikovexpresses frustration at JavaFX not delivering on early promises to make it easy for developers and designers to work together to build compelling user interfaces with JavaFX...

Kirill Grouchnikov posted Pixel complete:

In an indirect response to my earlier post, David Grace writes: "All this talk about not being able to create something that looks good in JavaFX is hot air. JavaFX has the functionality to do so, you just have to know how. What JavaFX needs is for the preview controls and layouts to be finished, controls such as a table implemented, and the Prism renderer implemented. When this is done it will be easy to write any application that could be written in Swing quicker, looking much better and with far greater performance. Personally i would of rathered investment in Swing instead, but..."http://www.java.net/blogfront

Conferences, JUG Meetings

Last week's java.net Spotlight was Justin Kestelyn's post Of Buses, Surfboards, and Communities:

Me and other members of the team, Vikki and Todd, specifically, had a blast at ODTUG's Kaleidoscope conference earlier this week. That group knows how to run one, and the results show it: attendance was up 25% this year. Kudos to the organizers. (Incidentally, Oracle ACE Director Edward Roske is the conf chair for 2011, so ACE Directors will continue to have a strong presence there.) As always, it was good to see the usual suspects. What's more, we got a visit from the Java Bus (#javaroadtrip), which parked right next to the conference space at the hotel...

Adam Bien talked about A Day in Paris (JUG) with Java EE 6:

Back from JUG Paris. It was almost a conference (~200 attendees). It was my first time in Paris -> I really like the city. Although I was said to got some competition by the football world championships, the room was packed.I predicted France to become the football world champion (I'm a true football expert :-)) - the attendees liked my expertise in this area. I started with slides and ended in the IDE...

http://farm5.static.flickr.com/4081/4744020080_a8ccccfd4b.jpg Why not keep the Java Bus at the top of "the Week in Review" for one more week? The bus travelled to Washingon, DC and then on to Charlottesville, VA this past week. Oracle Technology Network Chief Justin Kestelyn hopped on the bus in Providence, RI, and took the trip to D.C. In the picture, you see Roger Brinkley, of the java.net Mobile and Embedded community, demonstrating Java-powered Sun Spot devices. Atlanta, GA is the next stop on the Road Trip (July 8).

If you didn't get a chance to visit java.net on a daily basis in the past week, read on, and you'll find all of the week's Java Today news items, a selection of java.net blog posts, and the old and new java.net spotlights and polls.

Conferences, JUG Meetings

Last week's java.net Spotlight was my blog post Notes and Pics from the Java Road Trip Stop at Burlington, MA, USA:

The Java Road Trip spent an afternoon and evening in the parking lot at Oracle's Burlington, Massachusetts, USA office on Thursday, June 24. I had been working at the data center where I do most of my programming, and I pulled in beneath noisy skies, my car splashing through the puddles, as I strained to read the signs that identified each building and parking lot. Finally, I was in the right parking lot, and I saw the bus...

Last week's java.net poll was The "Java Road Trip" is happening now in the USA. Should a world-wide "Java Jet Trip" follow? 174 votes were cast, with just under half of the voters thinking a global "Java Jet Trip" would be a good thing. Here are the final poll results:

  • 85 votes (49 %) - Yes, why should only the USA have this type of Java community event?
  • 28 votes (16 %) - A better plan is for individual countries to organize their own national Java Road Trips
  • 37 votes (21 %) - No, these trips aren't worth the effort and expense
  • 21 votes (12 %) - I don't know
  • 3 votes (2 %) - Other

Paul Sandoz posted his JavaOne session schedule:

All done in the first half of the week (unless a repeat is requested), i like that :-) D#: S313265; Title: Advanced Java API for RESTful Web Services (JAX-RS); Track: Enterprise Service Architectures and the Cloud; Date: 20-SEP-10; Time: 13:00 - 14:00; Venue: Hilton San Francisco; Room: Golden Gate 6/7 ...

This week's new java.net Spotlight is Justin Kestelyn's post Of Buses, Surfboards, and Communities:

Me and other members of the team, Vikki and Todd, specifically, had a blast at ODTUG's Kaleidoscope conference earlier this week. That group knows how to run one, and the results show it: attendance was up 25% this year. Kudos to the organizers. (Incidentally, Oracle ACE Director Edward Roske is the conf chair for 2011, so ACE Directors will continue to have a strong presence there.) As always, it was good to see the usual suspects. What's more, we got a visit from the Java Bus (#javaroadtrip), which parked right next to the conference space at the hotel...

John Ferguson Smart announced that he'll be Talking in London: Zen and the art of build script maintenance-

Next week (on July 8) I'll be giving a talk in London for the folks at Skills Matter, on the much-neglected topic of build script maintenance: Build scripts are an essential art in any software project. And yet they are so often fragile, brittle and unportable things, hard to understand and harder to maintain. In this talk, we cover what constitutes a good build script, and look at a few of the...

Arun Gupta presented TOTD #142: GlassFish 3.1 - SSH Provisioning and Start/Stop instance/cluster on local/remote machines:

http://www.ibm.com/developerworks/java/library/j-5things7.html?ca=drs- GlassFish 3.1 Milestone 2 enables SSH provisioning that allows you to create, start, stop, and delete a cluster spanning multiple instances on local and remote machines from the Domain Administration Server (DAS). This TipOf The Day (TOTD) builds upon TOTD #141 and explains how you can create such a cluster on Amazon EC2 with Ubuntu 10.04. Carla also blogged about a similar scenario here. The cluster topology created is shown below...

The JavaOne Conference Blog is Kicking it Up A Notch with a Java Persistence API Quiz:

We know the last quiz was not the hardest one, but we wanted to start things off slow.  Now we are digging a bit deeper and have a list of questions around the Java Persistence API. Answer in the comment section below.  If all your answers are correct we'll list you in the next quiz post as a "Java Guru." Good Luck!!! ...

Eduardo Pelegri-Llopart provided an update on More GlassFish 3.1 Progress - M2 and Brown Bags:

Summer is here (and so is the World Cup), but the traffic on the GlassFish aliases is going up as we continue to move towards GlassFish 3.1. Last week was Milestone 2 which included several demos: SSH-based cluster management, Deployment and WebSockets (scripts only so far, screencasts on the way).  See Carla's post on creating and starting instances on remote hosts and also Arun's detailed TOTDs based on M2: #141: Running on Ubuntu AMI on Amazon EC2  and #142: SSH Provisioning and Start/Stop Instance/Clusters. Also, we have restarted the Brown Bags for the development team (we did a few back in 2007)...

Alexis Moussine-Pouchkine presented GlassFish 3.1 - Milestone 2 is out (more screencasts)

Julien Dubois wrote a new Sun Developer Network article, Part 1: Introduction to Jersey—a Standard, Open Source REST Implementation:

This article is part 1 of a four-part series. It briefly introduces basic Representational State Transfer (REST) principles, and then quickly leaves theory in order to build a real-life sample application. We will use the new Java Platform, Enterprise Edition (Java EE) 6 standard to create a classical JavaServer Faces application, and we will study why this application does not follow the REST principles. Using NetBeans, we will then add a second, Jersey-based view on top of our application, which will run in parallel with the JavaServer Faces front end. We will then compare both approaches to determine their pros and cons...

Cay Horstmann posted JSF and Power Windows:

In one of my previous blog, I provided some preliminary notes about running CAFE apps on top of Oracle Converged Communications Server (OCCAS) which covered two party call and voice conference. Now that we have MSRP support in CAFE for doing session mode IM, large file transfers, etc., which apparently works in OCCAS, it may be worth sharing a quick note on how to enable/use it in OCCAS. For...

Hudson Labs reported on a Digg Technical Talk:

Recently our fearless leader, Kohsuke Kawaguchi, was invited by the nice folks over at Digg to give a tech talk about continuous integration and automated testing. The Digg engineering team is full of believers in continuous integration, including our very own Andrew Bayer (abayer). Being big users of the Sauce Labs service to drive their vast Selenium test suite, the house was packed with Selenium hackers/users and Hudson users, the stage was set for Kohsuke to give a great presentation...

At JavaLobby, James Sugrue talked about My Latest Refcard: Apache Ant :

Today DZone are launching my latest refcard where I cover Apache Ant. The purpose of the card is to be a pure reference for the tasks available. This was an interesting refcard to write as I have been using Ant for so long, that I took the range of functions that it can perform for granted. While I'm sure a lot of you have moved on from Ant, it's still a widely used technology in a lot of software development organisations. It's present in all Java IDEs, and I still use it in my day job...

Hudson Labs reported on the 11th International Free Software Forum in Brazil

Last week, friend-of-Hudson Leandro Nunes sent the following message to the users mailing listregarding his upcoming talk on continuous integration and Hudson: "Next month I will present a talk about Hudson in the 11th International Free Software Forum (FISL 11), held in Porto Alegre Brazil (detailed time and date of the talk are not yet scheduled so)." FISL 11 is one of the biggest free software events in Latin America and will quite literally attractthousands of free software users, hackers, and enthusiasts...

On JavaLobby, James Sugrue announced an opportunity to Win a Free T-shirt: Who Are The Heroes of Java Data Persistence?

When Java started out, one of the big features that it offered was JDBC, providing a database independent way for Java developers to use relational databases. We've moved on a lot since then with the Java Persistence API (JPA), Hibernate and embedded databases. As with any technological movement, the success of data persistence in Java is down to a number of people...

Geertjan Wielenga posted How to Centralize the Management of NetBeans Platform Actions (Part 1):

When you use the Window wizard in the IDE to create a new TopComponent, you'll find an Action that looks something like this, registered in your layer.xml file, without any Java source file for the Action class being created in your module...

Geertjan then continued the series with How to Centralize the Management of NetBeans Platform Actions (Part 2):

Let's say we have a general TopComponent, which we want to share between multiple different modules. I.e., each module will provide its own Action. When the Action is invoked, e.g., from a menu item, a JPanel provided by the module that provides the Action will be added to the TopComponent, once the previous content in the TopComponent has been removed. Creating a generic Action providing the above functionality, following Jesse's corrections in the comment to yesterday's blog entry, you would do the following...

Kirill Grouchnikov described the New Office Black 2007 skin in Substance 6.1:

The latest 6.1dev drop of Substance look-and-feel library (code named Trinidad) completes the collection of skins that can be used on the Flamingo ribbon component by adding Office Black 2007 skin to the existing Office Silver 2007 and Office Blue 2007 skins. Here is how the ribbon looks under Office Black 2007 skin...

Geertjan Wielenga posted Exploring Serena Dimensions Support in NetBeans IDE 6.9:

Serena Dimensionssupport in NetBeans IDE, would it be similar to Subversion and Mercurial, as follows? The above is based on the skeleton versioning support plugin from here: http://versioncontrol.netbeans.org/cookbook.html...

On TheServerSide.com, Cameron McKenzie pointed us to two Hibernate tutorials in Hibernate 3.5 Without Hibernate? Using Hibernate Solely as the JPA Provider:

There was a bit of a backlash when the last tutorial on JPA and Hibernate 3.5 was posted here at TheServerSide.com. Why would we use the Hiberante API instead of just using the Java Persistence API, and thus shield ourselves from the underlying implementation? Well, the reason was simple. We wanted to demonstrate both approaches so you could compare them side by side! ...

Srikanth Shenoy presented Effective JavaFX Architecture Part 1:

Effective JavaFX architecture is not an easy task. Designing testable JavaFX applications that are beautiful inside-out requires serious thought and some experience. Or you could read this blog series :-)

Shai Almog talked about the Ginga-J Approval Process:

As you may know the Ginga-J specification for DTV (Digital Television) is becoming a national standard in Brazil by ABNT. Just in case you don't remember Ginga-J uses LWUIT for its component UI layer. The specification is now in the public comments phase, looking for feedback from the community/public. If you would like to see Ginga-J become a finalized standard for ABNT you can vote for that matter by...

Programming

On DeveloperWorks, Ted Neward presented 5 things you didn't know about ... Java performance monitoring, Part 1:

Blaming bad code (or bad code monkeys) won't help you find performance bottlenecks and improve the speed of your Java™ applications, and neither will guessing. Ted Neward directs your attention to tools for Java performance monitoring, starting with five tips for using Java 5's built-in profiler, JConsole, to collect and analyze performance data.

Tor Norbye advised Don't Use Implicit Return Types:

JavaFX, like Scala, is a fully statically typed language. However, unlike Java, it allows you to omit type declarations in many places, since it can infer it. Coupled with the fact that you can use expressions as statements, and that the last expression in a function will be the return value, this lets you write really simple and clear code...

Cay Horstmann presented The Horstmann Brace Style:

Now here's a topic on which everybody has an opinion—brace styles. As it happens, I have a brace style to my name, but I gave up using it because (1) other coders found it too weird and (2) no tools supported it. Until now, that is. Jim Pattee released a new version of Artistic Style, his excellent code formatter, that supports my brace style. Should I go back to it, or is it still too weird?

Alois Cochard invited us to Bring Your Code: An algorithm for index translation:

Here is a little code challenge ! I'm actually working on a text-mining/semantic web application focused (for the moment) on biomedical informations and developed in Java. We are using external tools for text-mining analysis and unfortunatly theses tools don't handle HTML pretty well ... If we send raw HTML to the text-mining service, he simply break. So we must convert HTML to plain-text before processing text, and because the tools return identified words by giving their positions, we must translate theses position (or indexes) to find corresponding word in the original HTML. I created a simply implementation and posted it on gist.github.com ... can you make it better ?

Open Source Projects

Josh Marinacci talked about the new open source XML Utility Library he's developed:

As part of some open source stuff I've been doing on the side I've had to generate and parse a lot of XML. I like working with the DOM because it's tree structure cleanly matches my needs, but the W3C API is *so* cumbersome. The DOM was designed to be implemented in any language, not just clean OO languages like Java, so any code using it will work but be ugly. After considering a few other XML libraries I decided to write a new one that would work with modern Java 5 language features like generics, enhanced for-each, and varargs. This library is super tiny because it simply wraps the standard javax.xml libraries in the JRE, but gives you a much nicer interface to work with. Here's how to use it (or download it here)...

Fabrizio Giudici asked What's the meaning of "Open Source" for the man in the street?

In the recent weeks I've been surprised by how I received related inputs, from different sources and their perspectives, about the same problem. For instance, two weeks ago, I read an interview by Simon Phipps about the future of OSI an I was hit by this passage: increasing consumer awareness of open source and the four freedoms (beyond the code and the geeks); Exactly the same day (cool) I...

This week's new java.net poll was stimulated by Fabrizio's post:What does the average non-programmer think about Open Source Software? The poll will be open for the next week.
