Tech Publishing Tips at JavaOne 2013

You've got tech knowledge aplenty to share. Maybe you blog. Or speak at conferences. Or conduct trainings. Or offer consulting services.

But have you thought of writing a technical book?

The fame, the fortune, the glory! (Okay, we may be stretching here....but anything is possible!) 

If you've seriously considered taking a step towards publishing a tech book or you're merely curious about what it would take, join me at JavaOne for the BOF panel session: So You Want to Be a Published Technical Author?, where I ask three publishers and two authors about the ins-and-outs of breaking into technical publishing.

The conference catalog currently lists two speakers (JavaOne system limit), but here's the full lineup:

  • "The Publishers"
    • Meghan Blanchette, O'Reilly Media
    • Joel Murach, Murach Books
    • Erol Staveley, Packt Publishing
  • "The Authors"

Bring your questions on anything and everything you'd like to know about getting published! It's sure to be an informative hour.

JUG Africa at JavaOne 2013

What am I looking forward to at JavaOne this year?

Moderating the panel session "Java Trends in Africa"!

BOF3649 (in the conference's content catalog)
Tuesday, September 24
7:30pm - 8:15pm
Hilton Continental Ballroom 5

The developer community in Africa is diverse and vibrant, and growing fast with more than 30 Java User Groups spread across the continent. Some are listed on the JUG Africa page, the umbrella group created by Max Bonbhel to connect the various local developer communities and to promote collaboration and shared learning.

On the panel, I'll be speaking with Max (CongoJUG) and Lamine Ba (SeneJUG) about what role Java is playing in the growing technology scene in Africa and how it's transforming the continent; what is being done to attract and grow a new generation of developers; what are the current challenges and opportunities facing developers; and more.

This is the first conversation of its kind at JavaOne (that I know of) and it's sure to be an engaging one! If you're attending JavaOne, schedule this one in your calendar.

One last note: Arun Gupta, Java evangelist extraordinaire, recently completed a Java EE 7 tour in Africa. His trip report is a recommended read for a glimpse at the breadth of the developer community in Africa and as a precursor to some of what will be addressed on this panel.

See you at JavaOne!

Best Tips for Attending JavaOne

NetBeans Podcast cohost Geertjan and I recently recorded an episode around JavaOne; we asked two guests: Toni Epple and John Yeary, about their tips for how attendees can get the most out of the conference.

About Toni and John: Between them, they have a combined 20 years of JavaOne experience from which they shared a number of useful conference tips that you can hear on the recording. After the interview, it occurred to me that the tips could definitely benefit a wider audience beyond the podcast.

Here's a mashup of things to do to have a productive and fun experience at JavaOne:

  • Pre-register for sessions. The popular sessions and labs tend to fill up fast. 
  • Stick to a theme. There's so much content at JavaOne it's easy to get overwhelmed. If you have a certain tech focus--Java EE, for example--keep the majority if not all of your sessions in that area.
  • Get to your sessions early.
  • Linger after a session. According to John, there's a good reason for this: the attendees who stay behind tend to have the most interest in a topic and are the ones with whom you can exchange ideas and develop strong professional and personal ties. Another reason to stay behind is to....
  • Talk to the speakers. They're developers just like you and friendly. And they really love to talk about their topic. (They wouldn't be at JavaOne otherwise!) Approach speakers after their talks and ask questions. It's a good way to learn more and build connections.
  • Identify your peers. How? Easy. The developers you keep seeing at similar sessions over and over again. Those who stay after a session is over chatting with each and/or approaching the speakers.
  • Schedule down time to hang out and have fun. Yes, JavaOne is about great technical content, but it's also a social destination! Drop by the booth and chat with the crew there. Attend the Java User Group events and parties and meet other developers.

Do you have your own tips from past JavaOne conferences? Share them in the "Comments".

On Games and Learning Languages - jMonkeyEngine and Quorum

What do I know about 3D games? The last video/computer/online game I played was.... Maybe Lexulous on Facebook? Hmm. Don't look to me for know-how on this subject.

Languages? Forget it. After seven years of living in the Czech Republic, this Summer I officially waved a white flag on learning the local language--resigned to my lot as yet another expat done in by Czech's maddening declension system. So far, I'm zero and five (0-5) with languages--human AND computer. (I'll save you the tales of my adventures in programming.)

My track record on both subjects aside, I recently published two interviews on NetBeans Zone:

Quorum is the second of the two interviews that I mentioned in my "update" post. Andreas Stefik, the mind behind Quorum (a new research-backed programming language), is a member of the NetBeans Dream Team and a passionate advocate for accessibility in programming. The idea for Quorum came out of his work designing SodBeans, an intuitive programming environment for blind developers based on the NetBeans IDE. (That project later won a Duke's Award in 2011.) I'm a fan of the work that the SodBeans-Quorum team produces, and when I learned a new version of Quorum was available I asked Andreas if he'd be available for a "short" Q&A. When it comes to Quorum and SodBeans, Andreas doesn't do "soundbites". He responded promptly and in full detail to my questions. The interview has done quite well on NetBeans Zone (over 9000 views and counting...), which hints at a sizable interest in the matter of how to make programming languages easier to learn.

The name Ruth Kusterer may ring a bell if you're a long-time NetBeans user. Ruth was a NetBeans team member (doc writer and book author, web mistress, and all-around solid gal!) during the latter part of the Sun Microsystem years. She moved on in 2010, but still keeps in touch. Heck, I saw her this morning on the way to work. (We share a business park.) Back in 2007, she developed a casual interest in 3D gaming after learning about jMonkeyEngine at a JavaOne conference. In the years since then, she has evolved from hobbyist to a jMonkeyEngine expert--producing and managing documentation for the jMonkeyEngine community. She sent us a note in July about her new book jMonkeyEngine 3.0 Beginner's Guide. Smelling content and tie-in (the jMonkeyEngine SDK is based on the NetBeans Platform), I asked for an interview.

So, for advice and insight on developing 3D games and programming languages I happily direct you to Ruth and Andreas.

A NetBeans UML Plugin Revival in Serbia

Here's the first of the two interviews I mentioned in the last post. My subject? Zoran Sevarac, an Assistant Professor at the University of Belgrade and a member of the NetBeans Dream team with an impressive list of activities around NetBeans and Java. He has served on the NetBeans Governance board; started a NetBeans User Group in Serbia; presented at JavaOne; hosted NetBeans Platform trainings in Serbia; and oh yeah, he sings too!

His latest contribution? Leading the community project to develop a NetBeans UML plugin. Read on. (The interview below is also posted to NetBeans Zone.)


A recent YouTube video stirred up some excitement amongst NetBeans users. In it, viewers saw first glimpses of a new community-led project--the revival of the NetBeans UML Plugin. The plugin is in development by a team from the University of Belgrade's newly launched Open-Source Center, and the team is led by Zoran Sevarac, an Assistant Professor at the institution and who is also a long-time member of the NetBeans Dream Team. In this interview, Zoran shares more about the plugin's development and roadmap.

What is the Open-Source Center at the University of Belgrade?

The Open-Source Center  is a part of the Department for Software Engineering at the University. The center is dedicated to the development of open source software projects and using these projects to also teach software development. (More about the Open-Source Center on NetBeans Zone.)

In what stage is the UML plugin currently?

The plugin is still under development--we're finalizing the first phase--it will soon be ready for an early-preview release. At the moment, people can use it to draw class diagrams, and I expect the plugin to have some basic code generation functionality soon.

What other features are planned?

We plan to do sequence diagrams for sure [since there is no good open source tool for that at the moment]. Most likely we'll do  module diagrams as component diagrams. After the preview release, when we get feedback from the community, we'll consider additional types of diagrams/features.

We also want to provide simple Java API for UML models (check out the sources in UMLModel module), and maybe some experimental AI-based algorithms for software design analysis in the future (similar to what's been done in Featureous).

Is the plugin (in its current stage) available for download and testing by the public?

Yes, the source code is available from SVN on . People can checkout and run it from the NetBeans IDE. However, I recommend that they wait another week or two, since we still have to polish some bugs.

There have been other attempts to create a NetBeans-UML plugin. How is your team's approach different?

Well, we want to create an easy-to-use, developer-friendly tool--a tool that will allow developers to quickly implement basic design and then continue coding. We want to provide enough features to be useful, and to leave out everything that developers don't find useful. Judging from the comments on Twitter and YouTube so far there are many users who likes this approach, and I want to thank Tim Boudreau for giving us insightful tips about UML tooling on his blog.

What challenges has your team faced on this project?

The first challenge was to learn how to use Visual Library for this project. We're still not experts, but I think we're now able to figure out what we need. Another was to keep the design clean and simple. I think we're doing well, though we've had do some refactoring from time to time.

An upcoming challenge is to create good documentation for the project so new developers are able to continue development. We have two students writing their graduate thesis about this project, so that will be a kind of introductory material for future developers.

Probably the most important of all is to create a good user interface and interaction design. It's not the main focus at the moment.

Why is it not a focus?

We want to avoid getting stuck with UI in the beginning, without having more experience with Visual Library. Our development strategy is to create a basic feature set, stabilize the design first, and then work on more fancy features related to UI. (Visual Library provides a pretty good user interface with basic features out-of-the-box.) We also want to get feedback from community and then decide how/what things should be done.

How many people are working on the UML plugin?

At the moment, three of us: Jelena Djordjevic, Uros Stojkic and me. There were also early contributors such as Jelena Stojanovic, Igor Cordas, Marjan Hrzic and Vedrana Gajic. All are my students. We also have some new potential developers who signed up for the project after the last NetBeans training in Belgrade we had with Geertjan [Wielenga].

Can the public get involved in the development?

Of course. Actually I'm hoping that something like that will happen after the first release. I've received some emails and questions about this already. The challenge will be to introduce them to the project; maybe we'll create some wiki on for that.

Do you have a target date for when the plugin will be ready?

Well, I'm hoping to have the first version available in the next few weeks. We'll do our best to have something ready to use in September--a demo at Java One 2013. :-) I'm having a session at JavaOne this year together with Sven Reimers and Jaroslav Tulach (Building Rich Visual Tools in Java) in which we'll share some experience and best practice from this project.

Good luck with the NetBeans UML Plugin project, Zoran. We look forward to hearing more about the next phases from you and your team.

A Mid-Summer NetBeans Update

For a moment it seemed as though history was about to repeat itself, wasn't it?

With this fifth post, I'm happy to report that it ain't so!

To mark getting back on track, here are five recent highlights--since the "pause"--to share:

  1. The NetBeans team started a gorgeous and sunny week in Prague this Monday by announcing NetBeans 7.4 Beta. Judging from responses on the NetBeans Twitter feed, there's plenty in this beta build that has users excited. A complete rundown can be found here.

  2. My NetBeans podcast cohost Geertjan and I recorded a [new] themed episode (#65) recently. We focused on plugins--Jelastic and JRebel, specifically. On most of our podcast recordings we cover a variety of topics, so it was a nice change to produce a one-topic podcast. We plan to do more of these in the future.

  3. The JavaOne 2013 notices went out in late June, and my two submitted BOF panel sessions (So You Want to Be a Published Technical Author? and Java Trends in Africa) were accepted! It'll be my first go at moderating/running a session solo at a conference. It's going to be an exciting experience.
    • (As always, a full line-up of NetBeans sessions and activities at the conference this year will be posted soon to

  4. Content-wise, I have two new community interviews lined up for the blog, and a few others on the way.

  5. Thank you, World War Z, for my new interest in Zombie fiction. #summerguiltypleasurereading.

JayDay 2013: Bigger and More Java

Let's list the many ways to introduce Anton Epple: NetBeans Platform consultant, trainer, developer and author; a blogger; a NetBeans Dreamteam member and recent Java Champion. It's an already impressive profile, yet there's more. Over the years, he has also steadily carved out a niche for himself as a conference organizer.

He got his start hosting annual NetBeans Day events in Munich for local enthusiasts and fans of the IDE. Each year, the gathering grew in size along with interest in a wider range of topics. Eventually, JayDay was born.

I reached out to him recently with a few questions about JayDay 2013--an all-Java powwow now in its second year that attracts an international crowd of Java developers and top Java experts.

This is your second JayDay event and the agenda looks to be bigger. What extras do you have planned for attendees this year?

We got great feedback for our JayDay last year, so we felt confident to allow more attendees and more speakers this year. The most important thing is that we decided to add a second track to give attendees more choice. Another extra is the embedded part, where we will show experiments with devices and sensors--that might be extremely cool. We're also trying to make the conference unique in that we're "eating our own dog-food". For example, we created a Java game for the JayDay website, as well as JavaFX-based presentation software for some of the talks.

You've already confirmed a number of well-known Java experts: Bien, Eisele, Grunwald, Weaver, and so on. What topics are they going to tackle?

We're trying to get a good mixture of great local and international Speakers, and actually the list has gotten bigger although not all the speakers have officially been announced yet. Simon Ritter and Gerrit Grunwald will both be covering different aspects of Java and JavaFX on small devices such as the Beagleboard or the Raspberry PI. In the JavaFX track, Wolfgang Weigend will share the latest information about JavaFX on the iPad and Android. Jim Weaver will talk about the cool new lambda expressions in Java 8. Adam Bien will do some great Java EE7 live hacking, and Markus Eisele will show how to test what Adam created using Arquillian. And I'll show how to write games for any device in Java. So basically we're covering Java on any device from Pi to Cloud. But I intend to add some more speakers and talks.

What inspired you to start the first JayDay conference?

I loved the NetBeans Day worldtour events back in the era of NetBeans 5. So a few years ago I decided to revive that and I organized a couple of NetBeans Days and meetings in my area. It was great to bring enthusiasts together and to do something for the NetBeans Community. The biggest event was in 2011. That year the topics were already getting more general, so we decided to broaden the scope to general Java. This is how JayDay was born. The first JayDay took place last year (December 2012). It was a great event, but I thought it might be even better in the Summer, when we can go outside to a typical Munich beer garden for lunch and the after-event party. :-)

Can you share a few tips about what goes into starting-up a new conference?

I'm still in the process of learning myself, but these are some of the more practical things that I've learned:

  • Do enough breaks. The attendees need breaks to walk around, meet and discuss the content. An important part of a conference is to be able to hang around with your peers and chat with the experts. That was the one thing we didn't have enough of last year because there was just too much great content and too little time.
  • Don't be afraid to charge for the tickets--it's a good registration reminder. :-) For free events sometimes up to 40% of the registered attendees won't show up. That can be very disappointing for an enthusiastic conference organizer especially if he has to pay for the catering. Even a small fee makes a big difference.

The JayDay homepage banner is actually a game called "Duke's Revenge". (But Duke seems to have a "death wish" and refuses to budge! Am I doing something wrong...?) Can you tell us more about this?

If you click the banner, a little browser game will load and you can use the "a", "s", and "d" keys to help Duke to protect Munich against some evil aliens. :-) The cool thing about this is that the game is written entirely in Java, but it doesn't require Java to be installed on your machine. It actually runs in every modern browser, even on the iPad and Android.

We call it the "Chuck Norris experiment", because up to now only Chuck Norris was capable of running Java in the browser without a Plugin. The trick is in a project called bck2brwsr started by Jaroslav Tulach. At its core is a virtual machine written in JavaScript together with an implementation of the Java Core APIs. This way you can run Java ByteCode loaded from regular JAR files in the browser.

What makes bck2brwsr special is that it doesn't tie you to a certain API or a set of widgets, but makes it easy to create your own APIs. It took me just one day to learn how to extend the project and create the API for drawing on HTML5 Canvas that I'm using in "Duke's Revenge". I'm really exited about this project and we'll definitely cover that at JayDay. By the way, the game is Open Source.

What would you like most for attendees to take away from this conference?

Our goal is to give them a ton of information about the hottest topics in the Java universe, and we want them to leave inspired to create their own cool projects. I guess what all the speakers of this conference have in common is that they're not only experts but also enthusiasts. They love to create cool stuff and share it with the community. So if we're able to get that across and share it with the audience I'll be more than happy!

Thank you Toni for the interview and best of luck with JayDay 2013.

Register for JayDay 2013.

Jarda Tulach on the Slopes

Every Friday I send out an internal content call for the NetBeans Weekly Newsletter. (You are subscribed to it, right?....)

Typically, what I get are referrals to technical articles, blog entries and event announcements. Standard stuff.

Once in a blue moon, an unusual submission lands in my inbox.

Last week, it was a video link with the following [slightly edited] note:

"Jaroslav Tulach, the last NetBeans founder still with the NetBeans project, won a silver medal in the National Championship of Masters Slalom competition in the A2 Category (men under forty). Video from the second round, which catapulted Jaroslav to his second place finish, is available on YouTube.

When asked if he was satisfied with the result, Jaroslav admitted to having spent too much time with computers in his youth rather than practicing skiing, so he could hardly ask for more.

"Hopefully, the majority of NetBeans IDE users will not mind that I didn't win, and it's okay for them that I founded NetBeans instead."

I've worked on the NetBeans team for six years-plus and I know many of the engineers have very fascinating lives (and personas) outside of the office. But since the note came in on April 1st--Fool's Day, I wanted to be sure.

So I wrote back, "Is that really you?...."

He sent this picture in response.

Congratulations Jarda!

A Quick Intro

My name is Tinu. Welcome to my Oracle blog.

Who am I?

According to my HR file, I'm a "Principal Program Manager" in the Developer Tools organization. Concretely, what I do is run Outbound Marketing for a very cool product--NetBeans IDE!

On a personal note: I'm Nigerian by origin; born in China; raised and educated in New York City; and currently living in Prague, Czech Republic, where the development hub of the NetBeans project is located.

Why am I blogging?

Good question! By nature, I'm a writer, a storyteller, a communicator. I enjoy telling and hearing stories. Stories are a great way of connecting and sharing experiences and knowledge. My intent is that I get to do that again on this blog.


Yeah....well, this is my second try at a "work blog". I started one a few years ago, but I was a perfectionist about the matter and produced a grand total of three entries before shutting it down. A pity too, because even with three entries I had already acquired some fans!

This time around, perfection is not the goal. Just consistency, and the patience to find my groove.

Also, I'm inspired by the blogging discipline of my NetBeans teammate Geertjan Wielenga. As of this post, he's clocked in eight years of entries about NetBeans!

"Go for it!" He said, when I brought up the idea of writing again.

And so here we are.


Call me "Tinu". I'm a Principal Program Manager for NetBeans IDE in Oracle's Developer Tools organization, and Country Lead for the Czech Republic chapter of Oracle Women's Leadership (OWL).
