FISL 10 Trip report

I’ve just spent a wonderful week in Porto Alegre, Brazil where I’ve landed to talk about OpenDS at the FISL 10 conference.

This is my first visit in Brazil and I must say that I didn’t get any good impression of the country in the first two days. As a matter of fact, I didn’t get any impression at all. I arrived on Monday evening around 9pm, it was all dark. After more than 16 hours of traveling, I just wanted to hit a bed.

On the Tuesday morning, thanks to the jet lag, I got up quite early, checked email and went for breakfast by 7am, noticing a rainy day and still pretty dark. I was just done with the breakfast when Bruno Souza arrived and took me to the location of the Javali meeting, an ancillary event of FISL, sponsored by Sun and organized by SOU Java and RS JUG.

We spent the whole day in the conference room, watching from time to time through the windows the heavy rain and wind. The Javali talks ended with pizzas and guarana and by then the night was already dark.

While I didn’t get to see how Porto Alegre looks like in the first days of my visit, I did enjoyed the friendliness of Brazilians. At Javali, trying to follow the presentations in Portuguese was though but I think I got probably 50% of the technical parts thanks to the mix of english words and to my understanding of Spanish. And when it was necessary, Bruno or Mauricio Leal would do some translation for us.

I didn’t get to talk at Javali, the agenda was pretty full and I hadn’t told Bruno I would be coming as I wasn’t sure I could make it. But Pat Patterson presented Securing RESTful Web Services with OpenSSO (and OAuth) and mentioned a few times OpenDS.

LP0_1039Wednesday was the first day of FISL and all the Sun participants went quite early to help setting up the booth in the Exhibition Hall. Sun’s booth was very well located and its main attraction was the thousands of small soccer balls that were given to attendees that registered to the OSUM program. I think that throughout the whole event, the Sun’s booth was the most vibrant and busy one, with Roger Brinkley making demos with his toys, Angel Camacho, Brian Leonard, Kirthankar Das and others helping with installs of OpenSolaris on attendees’ laptops.

Arun Gupta fired the event on Wednesday morning with his presentation demonstrating the combined power of GlassFish, MySQL and NetBeans to build web applications.

Friday was the busiest day for me as I was scheduled for 2 presentations. But before that, I was invited to participate in Simon Phipps talk show, describing in 5 minutes, what was OpenDS, what were the benefits for the Brazilian open source users and developers.

Immediately after, and in the same room, I did my presentation for OpenDS with the theme of "Scaling the Identity Store with OpenDS". The sessions talked about the 3 models we have in OpenDS for deployment :

  • Embedded in Java applications,
  • Standalone replicated servers,
  • LDAP Front-end access to MySQL Cluster’s network DB.

While FISL is mostly attended by students, my session had a majority of System Administrators, interested by simplifying and reducing the cost of their data-centers.

Later in the afternoon, I was presenting again, repeating JavaOne’s presentation from Tony Printezis and Charlie Hunt GC Tuning In the HotSpot Java Virtual Machine. Charlie was meant to attend the event, but the week before found out he could not make it. As they recalled I was in the room at JavaOne and I’m quite familiar with the subject as we’re spending a lot of time trying the different options to tune the JVM to get the best performances out of OpenDS, they asked me to cover the talk. I think I’ve done a reasonable job, despite the density of information in the slides, and the simultaneous translation in Portuguese for the largest part of the crowd not so familiar with English.

Still on Friday, part of the exhibition floor was closed to the public as the Brazilian President, Lula Da Silva, was schedule to visit the event. Sun booth was very well positioned, on the border on the closed area and the crowd started to gather by the booth as President Lula arrived. The excitement was amazing. When the President reached by the OpenSolaris Brazil user group, he received an OpenSolaris cap and T-shirt from Vitorio Sassi, Sun employee and one of the leaders of the Brazilian OpenSolaris community.

On Saturday and last day of the FISL conference, I got to share a little bit more of the stage by answering a performance related question from the attendance on Bruno Souza’s session about the future of Java,with the exceptional presence of Javali, the mascote for the Javali user group.

Overall FISL has been an amazing experience. It is definitely the biggest open source I’ve participated to. Over 8200 registered visitors, from 27 different countries, more than 320 speakers for 354 presentations and a presidential visit. More than that, Brazilians are extremely nice, generous and happy to live. They made our stay in Porto Alegre something that I’ll remember for a long time. A special thanks to the main organizers: Bruno Souza and Eduardo Lima (here below with Simon Phipps)

I’ll definitely participate to the Call For Presentation next year, if evangelism of the OpenDS project is still one of my tasks for next year.

Opends Logo TagThe OpenDS development team is very pleased to announce the immediate availability of OpenDS 2.0.0-RC3, the third and probably last release candidate for OpenDS 2.0.

OpenDS 2.0 has a number of new features over OpenDS 1.2.0 that was released in February 2009 :

  • A new mode for Multi-Master Replication providing greater consistency and availability of data: Assured Replication
  • Recurring tasks allow an administrator to schedule repeated tasks such as backups
  • New extensible matching rules and indexing allowing comparing, ordering of data according to specific locales and languages
  • Better monitoring information for the server and for Replication
  • Full compliance with RFC 4518 and matching of UTF-8 in attributes with a DirectoryString syntax
  • VLV indexes are now built during the Import
  • Several improvements in the Control Panel
  • Works with IBM JVM (Java 6 SR4 required)
  • Works by default with JConsole and VisualVM when JMX Connection Handler is enabled
  • Default settings and ergonomics have been improved reducing the need for tuning parts of the server
  • Greatly improved performances and stability over time of those performances
  • Resolved a possible security issue when Pre-ReadEntry, Post-ReadEntry and Assertion Controls were enabled

Overall, over 170 issues have been fixed.

The purpose of the Release Candidate is to solicit one last round of testing before the final release.

So please test the OpenDS release with your client applications, in your environment or on your favorite platform.

If “God” says it…

…It must be true.

James Gosling
In a interview published this monday in eWeek Europe, James Gosling queried about Innovation in Java, replied the following:

"It’s all over the place inside Sun. People are doing cool things in any direction you want to look. The enterprise guys — the GlassFish group — they’re totally on a tear these days. The OpenDS guys are being really successful. The OpenJDK guys are getting some real traction. Stuff like the Jigsaw modularity stuff is getting a lot of excitement."

As one of the OpenDS guys, I like the middle of the response… And so it must be true !

OpenDS in Brazil

This week, one of the biggest conference about Open Source Software takes place in Porto Alegre, Brazil: FISL.

FISL stands for "Forum Internacional Software Livre" in the Portuguese language and means "International Free Software Forum".

FISL 10

This will the 10th edition and already over 6000 people have registered, according to the organizers.

It’s the first time I get to go to FISL and to Brazil as well. I’m looking forward to it, as I’ve been told a lot about the energy and the good atmosphere of the conference. It will be a good opportunity to be in touch with our community from South America.

My session will talk about "Scaling the Identity Store with OpenDS", describing the options to scale OpenDS based LDAP directory service from very small embedded to extremely large, telco scale. It’s schedule to happen on Friday 26th, from 11am to 12am in room 41A.

See you there.
