Special limited offer: extra seats for Date & Time session repeat

Those of you following my work are probably aware we'll be presenting a JavaOne session about JSR 310, aka the new Date & Time API. The original session got full a few weeks ago, so a repeat was scheduled a few days ago. Unfortunately, it also got full last week.

The good news is that our Thursday session was moved to a larger room, so now there are around 60 seats available. So, if you are interested, rush up: login to Schedule Builder and secure your seat, cause it seems Date & Time is hotter than people assume ;-)

Final JavaOne report

Ok, so after a long trip home, I finally managed to write the final installment about JavaOne.

In the morning, I attended Gavin King and Bob Lee's talk about Web Beans. The coolest thing about Web Beans is actually its dependency-injection support and the rich lifecycle model they are proposing. It is actually a merge between Seam and Guice strategies. It would be applicable to any kind of application, not only web-based, so my question was if they intended to split the spec so these features could be used, well, anywhere. They like the idea, but it is too soon to say. Let's hope they eventually do it. Watch out, Spring!

Then I attended the Effective Java Reloaded session. I haven't attended the 2006 session, but a few folks said it was too similar to last year's talk. I've already applied - and advocated - many best practices suggested during the talk, specially making everything final. By the way, Gavin, Bob and Joshua are great speakers and members of this group were in short supply this year. Sigh.

In the afternoon, I've (accidentally) spent some time with some NetBeans guys. First Roman Strobl:

I've told him a little bit more about my NetBeans pledge (expect a follow-up post about it). Then I came across Geertjan again, that showed me his musical notepad (you can find it at nbjfuguesupport). Guilherme Silveira was passing by and decided to make a video about it. He posted the first part in YouTube and hopefully he will upload the second part soon.

After that, I've attended the last few minutes of the session named "Stress Your Web App Before It Stresses You: Tools and Techniques for Extreme Web Testing". It was quite packed and it seems people liked it a lot. So, no need to be worried, Felipe!

Basically I spent most of the time in the afternoon and early in the evening. Then, I was at the Java Champions BOF. Java Champions are recognized by Sun as leaders inside the community. Some of them are Kathy Sierra, Bruce Eckel, Joshua Bloch, Neal Gafter, Jason Hunter, Calvin Austin and even myself. It was good to meet some of them and also to meet the program coordinator, Aaron Houston, a very nice guy.

Finally, it was show time: our BOF about JSR-310, Date and Time . As noted by Timothy O'Brien, the number of people who attended was impressive. Her is a partial picture:

We showed a few slides and some code Stephen started working on recently; we expect to commit this API to SVN soon. The audience made interesting comments and questions during the talk and after it - we had to stay there for almost an hour after our talk to address all questions. Some spec leads for JSRs that will make it to Java SE 7 were there and showed they intend to use our work and to support it. So, JavaOne selection team, keep it in mind for next year: date and time is a hot topic.

Once I had completed my main mission, I had a meal with some other Java Champions/JUG Leaders in a nearby restaurant. It was quite nice to meet these folks, shall I say.

From Thursday, I would like to highlight the excellent JFugue talk delivered mainly by David Koelle and with special guest star Geertjan Wielenga. David is a terrific speaker, his work is amazingly cool, his demos rocked and he managed to be funny. Geertjan also deserves congratulations for focusing on the main topic, JFugue, instead of just pushing NetBeans. Of course he mentioned his application was NB-based, but he actually focused on demonstrating how JFugue was simple to use, which just makes more people interested in his application and, well, NetBeans. So, another note to J1 selection team: we want more music-related talks, preferably with David!

Fabiane Nardon and Daniel Lopez's BOF, Designing Self-Evolving and Self-Configuring Java Platform, Enterprise Edition (Java EE) Applications, was also quite interesting and attended by several Java Champions. Nice job! The BoF I've attended after it was one of the coolest sessions in JavaOne: The "java.lang.OutOfMemoryError: PermGen Space" Error Message Demystified, presented by Frank Kieviet and Edward Chou. I couldn't believe they could actually spend 50 minutes talking about this topic with valuable information, but they actually did it. Having done a lot of profiling and OOME chasing before, I must say I could not explain the issue better. You must be on the Rock Star Speakers list for this year.

Fabiane and Edgar's session on Friday was very successful as well and Linda deMichiel and Kenneth, from JPA 2.0 and EJB 3.1, came to them after the session to look for input for their specs. Joshua's Puzzler session was really cool as well.

So, it was nice to meet everyone I didn't know in person before and to talk to all of you I've already known. See you in JavaOne 2008 (if any of my submissions is approved)!

2006 JavaOne Conference Call for Papers is Open

Just received an email from Sun:

Dear Michael Santos,

2006 JavaOne Conference Call for Papers is Open!

JavaOne, Sun's 2006 Worldwide Java Developer Conference, is seeking 
proposals for sessions (technical talks and BOFs) for this year's 
Conference.

The 2005 conference attracted over 14,000 developers and leaders in 
the Java technology industry. It was a celebration which included 
many of the industry's best and brightest.

The JavaOne conference is your opportunity to reach this specialized 
community by educating and sharing your experience and expertise with
the Java technology.

Please go to http://www.cplan.com/sun/javaone06/cfp to review the 
guidelines and instructions to submit your proposal(s). 

I presented a BOF in 2003 and it was a great experience. One thing that bothered me about the last two editions (which I did not attended, by the way) was the number of Sun speakers and the fact there were very few talks about real hot topics (AOP anyone?). If anyone from Sun is reading, please change this!

It is better to run: the deadline is Nov 30th! Time to start thinking about what to submit...

A few words about Brazil, Java technology and myself

If you have been to the last edition of JavaOne, then you probably have seen me :-) I was one of the crazy, shameless Brazilian guys who attended the conference this year. No, I wasn't the "Brazilian superman", as one guy who works for Sun named Bruno Souza, our Javaman. :-) But, getting back to the point, there is a lot more about Java development and Brazil than you might know.

To begin with, as Manoel Lemos and Beatriz Leao mentioned at their session, we speak Portuguese - yes, we don't speak Spanish and we are more than 50% of Latin America, what means most latins speak Portuguese! We are the 12th largest world economy and our capital city is Brasilia, not Rio de Janeiro, Sao Paulo nor Buenos Aires (that last one would make some of us really angry :-P) And some national wide projects are entirely or mostly Java technology based. Oh, probably the most surprising fact: our JUGs are the largest of the world! The #1 is SouJava, which I am glad to be part of and help to coordinate.

As this is my blog let's talk a little bit about me: currently, I am working on a application that is going to be used by one of the main industry players here and it's going to control nearly everything they do. My Ant builds are taking ages - ok, 5-7 minutes, but that's ages from a Java developer perspective :-P - and I think our code base is still going to get 5 times bigger! That is what motivated my java.net main project, called AntG. Its main purpose is to make Ant builds run faster by using threads and taking advantage of grid computing. If you are interested, check it out! Give your suggestions and join the project. We are still limiting its scope and deciding how to begin to implement it, so all of you are welcome. Right now, we are discussing everything in Portuguese, since we are all Brazilians, but if you join, identify as a non-Portuguese speaker and we'll do our best to write in a language you understand - as long as it is English or Spanish. :-)

I intend to publish some useful and practical tips here and also to talk about my other projects, so keep checking my blog out.

Regards,
Michael "MisterM" Santos
