Taking the JavaBlackBelt Challenge at Javapolis

2006-12-20
Even though we weren't handing out fun swag, like free beer (Sun and BEA), we enjoyed constant attention. Over 300 "watchers and/or "takers" of the contest continually lined up behind our 3 laptops. (Note to ourselves for Javapolis 2007: bring 5+ laptops.) One of the highlights was meeting David Michiels, a Java developer at Certipost.be

Spring Core (non Basic) exam released

2006-10-20
John Rizzo, from Belgium, released the Spring Core (non basic at all) exam, which gives you 9 knowledge points.

It requires 50 contribution points. In the near future, and we might temporarily lower this to 0.

Bigger, faster, better

2006-10-18
We migrated the platform to a new server.


It's more reliable. The server cash disk of July 17 2006, lead us to a slow and painful recovery process. We are based in Brussels (Europe) and Javalobby in North Carolina. Their hosting provider is in California. So, we had one intermediary and 2 time shifts. I skip all the troubles we run into, despite the great help of Matt (Javalobby). We finally lost valuable images associated to Swing questions, which we had to put back to Beta.


The new server has raid, mirroring and daily disk backup, additionnaly to ftp data backups. It's also in a datacenter from our city: if it burns, we just take the car and throw water on it. The mass of accumulated data (questions) and the new Corporate Edition (more on this soon), made the reliability a much more critical need.


There are 2 servers in fact. No that we need more power: 1% of the CPU is used by this great JavaBlackBelt software - thank you team! But we plan to provide a killer feature: programming (non multiple choice) questions, where your answers will compile and run on the other server (end 2006).


You probably noticed the improved speed, probably caused of the larger bandwidth.

Since May 2005, the guys behind JavaLobby.org generously paid to host JavaBlackBelt. We'd like to shout out a huge thanks to Rick Ross and Matt Schmidt for supporting us!

TechAnim on The Server Side

2006-10-09
A JasperReports TechAnim authored, by John Rizzo, co-founder of JavaBlackBelt and Teodor Danciu, of JasperSoft, has been published on the TheServerSide.com

Entitled Your Code Execution, this uniquely designed technical animation uses clear navigation and narration as it takes you step by step through the process of creating a Jasper report from an XML report definition.

Java SE Networking exam released

2006-11-23
Brown Belt Eric Wendelin, released the Java SE Networking exam, which gives you 3 knowledge points.

Shipping problems

2006-11-03
The procedure is to send an auction item using the delivery address provided by the user. The publisher or distributor handles delivery. The only tracking we have is an email stating the date it was sent. In particular countries we don't have access to additional information even when we send it personally.

We know this is frustrating. It is for us too: we have to pay for packages that never reach their destination. What's more, Café Press told us, "We don't guarantee shipping fulfillment."

Starting today there will be concurrent auctions: electronic Amazon gift certificates (Amazon guarantees orders) and books/T-shirts (fulfilled by publishers/Café Press.)

If you live in a place where the postal service isn't reliable, bidding for a book/T-shirt is at your own (points) risk. If you would like to suggest other types of gift certificates that can be used in your home country, please let us know.

For users who have won a recent T-shirt auction that live in countries that have delivery issues your points will be returned.

Thank you for your patience and understanding.

Bonus Points

2006-10-24
A new feature is active on JavaBlackBelt, to help focus contributions.

You probably noticed that when adding a question to the Java SE - Basic exam, you get a discouraging message. This exam contains too many hard questions and we need to slow down the contributions there to ease the manual filtering (question moving).

We also bring a motivating way to focus question authors where it's the most useful: a bonus factor associated with some exams.
For example, most Hibernate exams now have a x2.0 factor to double your contribution points.

JavaBlackBelt at J-Fall

2006-10-19


Last week we gave a talk at J-Fall, organised by the Netherlands Java User Group.

Our contact with the group was Bert Ertman. (Thanks for getting us involved, Bert!)

We are pleased to report it was a great conference - and experience.

More than 600 Java developers attended the event.

Our Hibernate 3 session was a big success. Nicolas, who led the session using his TechAnims, delivered the presentation to a room filled with attentive, enthusiastic developers -- who were mainly Dutch nationals. (Our talk was given in English, but there were several sessions available in Dutch.)

We set up a booth with our Netherlands partner Finalist to present the community and our services.

We organised a contest promoted by our Black-Belted Bella who "Hai yah'd" attendees into taking the exam challenge.

The winning challenger was Peter Doornbosch who received two books for passing the exam first.

We got to meet JavaBlackBelt community member and brown belt Mario Klaver. We heard another community member was there, blue belt, Jettro Coenradie. Unfortunately, we didn't end up meeting him. (We'll catch you next time, Jettro! ;-))

JavaBlackBelt at JAOO 2006

2006-10-12

Nicolas and I were given the opportunity to speak at the JAOO conference in Denmark. It was the first time we attended this conference - a memorable experience for us that went beyond that "newcomer" sensation.

The organizers impressed us. JAOO, created ten years ago by Danish company EOS, is a popular conference. Its success goes beyond its employees. An entire community is centered on JAOO. The feeling this gives is difficult to put into words - to experience it is really incredible.

The company and community dedicated to the conference amazed us. It was evident that everyone involved put forth a great deal of leisure time into it. The commitment of students from Danish universities, a.k.a. "The Crew" volunteered every type of assistance wherever they could. It was inspiring to see every person involved in the conference was also integrated into their city and their national culture: health. Each year the JAOO-IT Run, a sporting event, is organized around the conference to encourage attendees to get more exercise.

The level of dedication and community efforts made me think of this group as a Small Giant, which refers to a book I am reading. A Small Giant is a company (or organization) that has opportunities to grow but chooses deliberately to remain small (in the numbers sense) with the goal to maintain excellence. The main principle is harmonious integration of a community centered on a company.

Our own sessions at the JAOO were successful - another reason we had a memorable experience. Every seat in our sessions was filled. We presented a dozen TechAnims about Spring and Hibernate technologies called Extreme Visual Learning. (A similar example, the Jasper Reports TechAnim was published recently on the web in cooperation with TheServerSide.com.) Feedback from the attendees was very positive. Talking about Spring with .NET developers is refreshing and rare - an experience that is difficult to find at many conferences.

That leads to the last point: JAOO is about developers as a community. It's not only for Java developers (like us), for .NET developers, and the rest. We are developers — FIRST. Sure, some topics and technologies will attract more interest from Java-focused programmers. But, many topics go beyond technologies (concurrency, DSL, methodology...)

Next up for Nicolas and I:
The J-Fall conference in the Netherlands.
