SiliconIndia, India’s professional networking portal, is organizing Mobile Application Conference India in Bangalore on this Saturday. Sun is a technology partner of the conference and it is an opportunity for you to see Sun's mobile technologies in action. I was told that there will be also a demonstration of Java ME SDK 3.0. Sun India team is looking forward to meeting you there if you have a chance to come.
Mac developers have often asked when Java ME SDK 3.0 will be available for their operating system. We always answered that we were working on it. Today is the day when it happened, we have released Java ME SDK 3.0 Early Access for Mac OS X. You can download it from http://java.sun.com/javame/downloads/sdk30.jsp.
Highlights of Java ME SDK 3.0 Early Access, Mac OS X:
Last week was very interesting for us. We spent two days in usability lab observing how people use Java ME SDK 3.0 and we collected a lot of useful information from this usability study.
We could see four usability study participants every day. Some of them were professional developers, some of them students with different level of Java ME knowledge. It was a really edifying experience to observe people with varied Java ME skills using a product which they haven't had seen before. Each participant got one and half hour to finish three tasks. The tasks were designed to cover general product functionality as well as specialized features, e.g. sensor emulation. Java ME SDK engineering team did a lot of notes and we are also looking forward to results from the user experience team who organized the study for us. We should get the results next week but we have already started to think how to improve the product usability.
Do you want to know how the usability lab looks like? It consists of two rooms, darkened and well-lid, separated by two-way mirror. It allows people in the darkened room to see into the lighted room but not vice versa. I'm sure you know this kind of room from criminal movies. In our case the rooms are equipped better than on police stations and usability study participants feel there more pleasantly than suspects in police interrogation room. We are also much more friendly than police officers :-)
The participant sits alone in the lighted room and working on usability study tasks. Participants are asked to think aloud to allow observers in the next room to follow their mind. User experience team is recording participant's voice, face and desktop to be able to analyze their work-flow later.
We'd like to thank to all participants for attending Java ME SDK usability study and to user experience team for organizing this study. It was very inspiring for us. Thank you!
Following pictures show participant and observers rooms.
This is what really didn't happen during the usability study ... at least not during our study :-))
Today I'm not going to write anything serious and even anything related to the mobile development. As every working day I came to the office, started to read emails and found one with a link to A Tribute to Sun Microsystems web page. It moved me back in time. Before I joined Java ME SDK team I was a member of NetBeans engineering team, working on different parts of NetBeans IDE. I spent eight years working on this great product and from this time are also pictures which want to show you. Trip to one cold February day eight years ago starts here :-)
Looking out from the window it seems that autumn weather came to Prague. Winter will be here in a few months and hopefully there will be good conditions for another snowball batlle, this time between Java ME SDK and JavaFX teams :-)
PS: I'm throwing the snowballs from the farther terrace.
That's a question we have got a lot of times. It was answered here and in different forums, describing why it take some time to release Mac version so I'm not going to write the reasons again. Today I'm going to show you something behind the scene. We are running Scrum process while developing Java ME SDK. Next two pictures were taken at the end of our latest sprint.
The first pictures shows our office board with table of stories and their tasks. As you can see we finished all tasks.
The second picture is more interesting. It shows burndown chart, which is a is graphical representation of work left to do versus time. The green line represents the ideal burndown. You can see that our progress was under the ideal line. It means that we worked faster and finished our tasks sooner than we expected when planning the sprint. Especially in the beginning the progress was quite rapid so in the middle of the sprint we added a few extra stories and we achieved all of them.
That's what is happening in our team and hopefully answers the title question. Java ME SDK for Mac is in progress and it goes well ... stay tuned – coming soon to a computer near you!
Three weeks ago has been released NetBeans 6.7. This release integrates Java ME SDK 3.0 so mobile developers can now use all advantages of NetBeans Mobility and Java ME SDK 3.0 together for their development.
For more information visit NetBeans 6.7 release information page.
Today they are three months we started our team blog (and it is also my grandmother name day :-) ) Here is a map of you, our readers.
I'm back from Java Mobile, Media & Embedded Developer Days - Latin America (M3DDLA) and I'm still full of impressions from this conference.
M3DDLA was hosted by Senac University, Faculdade de Tecnologia in Goiânia, Brazil and organized by GoJava, Java community of Goiás (state of Brazil). Java has a very big and very active community in Brazil and I could see it at the conference. A lot of people interested in mobile Java technologies registered and came to M3DDLA. Each session had a big audience and there were a lot of questions at the end of each presentation. It was very nice to see Brazilian passion for Java. I can't help myself I have to say that it was the best conference which I've ever been to!
The success of M3DDLA would not be possible without a great organization. I want to say here once more 'thank you' to Murilo, Raphael, Roger, Terrence, Mauricio, Flavia, Filipe, Marcos, Leonardo and all other who I don't know by their name and who worked hard to prepare this excellent conference. Also thanks to everyone who came to visit it because without your audience M3DDLA would have never succeed!
My special thanks go to Jose Luiz Uzeda de Oliveira, manager of Address West Side Hotel Residence where all conference speakers stayed. He and his team did the best for us to feel there as at home and we really enjoyed it.
Four days in Goiânia wasn't just a conference. It was also learning about Brazil. Now I know much more about Brazil than I knew one week ago. Great part of this learning was tasting Brazilian food and drinks. I still remember the taste of tucunaré, feijoada, brunch, cupuaçu, Guaraná Antarctica, caipirinha :-), etc. I can't also forget the trip to Pirenópolis which our new friends organized for us. It was a really nice day ended by swimming under waterfall. It was my first time in Brazil and I hope not last time because this visit still comes back to my mind. Thank you Murilo, Heloisa, small cute Lara, Raphael, Alice, Filipe, Marcos, Leonardo, Igor for spending your free time with us and making our Brazilian experience!
Muito obrigado!
JavaOne is over and next Java conference is coming. This time in Goiânia, Brazil. I'd like to invite everybody who is interested in Java ME to Java Mobile, Media & Embedded Developer Days - Latin America. We will be there and will present Java ME SDK 3.0. Come to meet us and see what is new. For more information about the conference visit its home page.
Java Mobile, Media & Embedded Developer Days - Latin America
Goiânia, Goiás, Brazil
June 20, 2009
Senac Goiás Technology University Auditorium
A Closer Look at Java™ ME Platform SDK 3.0 presentation starts at 11:00am.
If you have missed Java ONE, you can see a short screencast showing something, that Tomas presented: Java Platform Micro Edition Software Development Kit Prototype running on Mac OS X. (direct link to a HD .mov video, 22.8 MB, 3 minutes)
JavaOne starts in few days and we are getting ready our demos for java me sdk session on thursday June 4th 9.30 am. It is exciting and I hope it will be exciting for audience as well. This time we will concentrate on working with real handsets. How to deploy applications, do debugging or device profiling directly on the phone with (almost) only one mouse click. There will be also a small bonus for Mac and Linux users.
There is JVM for Windows Mobile device bundled with Java ME SDK. Have a look at installWinMobile.pdf in SDK doc folder. Pdf says how to install and use it on device and also with Windows Mobile Emulator. This jvm is for evaluation purposes only which means that you can deploy on it only from SDK.
Just a day after Java ME SDK 3.0 release we decided to have the first meeting about features for next Java ME SDK version. It was a nice sunny day in Prague and we were sitting on the grass in front of our building to get fresh ideas on the fresh air. We put together long list of enhancements and new features but we would also like to know your opinion. Do you miss some feature? Do you think something should be improved? Share your mind with us, we will very appreciate it.
From left to right: Radko, Martin, Tomas, Ondra, Lubo, Igor and Pavel behind the photo camera.
We've got some time today to celebrate our release finally. Besides engineering many thanks goes to our quality engineering team for testing, Netbeans core, profiler and mobility team for support, cldc engineering team and all other who contributed and helped to make it happen.
Sending piece of cake to all of them at least virtually ...
A nice article about Java ME SDK 3.0 was published on DevX.com. The article is discussing Java ME SDK 3.0 Early Access release but what was written is still valid for the final version released last week.
