I will for sure miss the massive input and inspiration this conference gives me and enables me to keep up-to-date on everything that is happening in the Java Community. This year’s conference is also special since it is the first time Oracle is hosting the show. It feels like a good idea to co-host it with Oracle Develop and I hope it will be a success to be continued. Next year, I will definitely be attending, one way or the other…!

The solution is as simple as you would expect when you have used NetBeans for a while. Add the following to the build.xml file in the project root (replace the dummy values for the signjar target):

<target name="-pre-jar">
   <copy todir="${build.classes.dir}">
      <fileset dir="${external.libs.dir}">
         <include name="*.jar"/>
      </fileset>
   </copy>
</target>
<target name="-post-jar">
   <zip update="true" destfile="${dist.apk}">
      <zipfileset dir="${external.libs.dir}" includes="*.so" prefix="lib/armeabi"/>
   </zip>
   <zip destfile="tmp.apk">
      <zipfileset src="${dist.apk}">
         <exclude name="META-INF/*.*" />
      </zipfileset>
   </zip>
   <move file="tmp.apk" tofile="${dist.apk}" />
   <signjar jar="${dist.apk}" alias="alias" storepass="secret" keypass="secret2" keystore="my_keystore"/>
</target>

You also need to add external.libs.dir=<your lib folder> to you <project root>/nbproject/project.properties file.

Now you can install the resulting .apk file using adb install or by running/debugging directly from NetBeans. Remember to follow the tip for asset-files in a previous post if you have that kind of resources.

At first, I was skeptical to the whole idea thinking it would generate an overload of noise for a couple of weeks until dying slowly like most initiatives to share knowledge within companies. But after having thought about it, I really hope that will not happen. It is actually a brilliant way of building a knowledge base within the company. Everyone who has tried to establish some form of knowledge exchange know how hard it is to get people to contribute.

But by “hiding” it behind some familiar technology like twitter, people actually contribute without knowing it. If you think about it, only the things people are interested in will be posted and discussed in such a forum. People will only put energy in discussions they have strong feelings for. The things most people have feelings for are probably pretty relevant things for your organization. And it is by default fully searchable with the newest items most visible.

So with my limited experience of yammer (have used it two days), I will conclude that it is actually a good thing. Now we just have to hope that it does not die a silent death when it is not that new-and-cool anymore…

Even though we are out there exposing ourselves on facebook, blogs and twitter, we are not comfortable sitting next to someone that are watching us typing while we are writing our blog post or tweet. As soon as we hit the submit button everything changes. Now we actually want people to read the stuff. That is why I call this

our irrational fear of real-time exposure

Exposure is fine, which the popularity of facebook and twitter are evidence of, as long as we are not caught doing it. Feel free to tweet, blog or comment on this

Well, over to what this post is all about: the conference. The keynote was held by Scott Hanselman. He gave an excellent talk about effectiveness and efficiency. Some really good stuff to bring back from that speech. Will try to list some of the techniques and tools he mentioned in a later blog post.

I will also summarize the rest of the sessions I attended today very soon here…

Great conference!

Ola Bini presented the folding language Ioke. I will definitely download this and play around with it. Hopefully, I can use it in some presentation in near future. Really cool and fun!

The next presentation I attended was Neal Ford’s presentation about XP in practice. Nothing really new there, but more a confirmation that what I feel we are doing right applies to others as well. And, more valuable, tips and techniques for how to improve on what we are doing not so right. At last a kind of nerdy way of looking at pair programming:

• 100 eyes
• 010 brains
• 001 mind

Continuing on the agile track, Dan North gave an excellent talk about our obsession with efficiency. The three key points to remember from his talk is:

• You get what you measure
• Not all vendors are bad guys
• Efficiency isn’t effective

Back to the languages track, I attended a talk by Neal Ford where he compared Groovy and JRuby. It gave me a pretty good comparison of the benefits and drawbacks of both languages.

The only session on the Java track was a disappointment. The only thing I really got from this presentation was that I could charge my netbook’s batteries. Still running OpenSolaris on it, by the way, and is generally happy with it!

Last technical presentation today was about clojure. Kind of tough thing to jump into this late in the afternoon, but the presenter, Stuart Halloway, did a great job.

In the afternoon keynote, Cameron Purdy did a comparison of Java and C++.

Overall experience from the first day of the conference is good. It is impressive that they have gathered so many international speakers. If I should pick on something, it has to be that the opening of the conference would benefit from being a little more flashy. Maybe have the opener learn his speech and practice on the English pronunciation…?

And now, it is time for mingle and beer!

My intentions are to use this blog for subjects that cannot easily be said in 140 characters and twitter for the short, more daily stuff…

Well, so what has happened since last time. Since I have solely been using NetBeans the last couple of years for Java development, I decided to give Eclipse Gallileo a chance. It took me an hour of frustration to conclude that it still sucks for Maven based projects. Why it should be so hard is beyond my comprehension! In NetBeans, you just choose open project, selects the pom.xml file and everything is fine. Dependencies are resolved as they are defined in Maven, no stupid .classpath, .project and .settings rubbish created that makes Eclipse to totally hick-up if a dependency is changed.

Apart from my unsuccessful flirt with Eclipse, I have continued development of KanbanFX. It has been converted to a maven project and besided the information on Kenai, I have created a page for it here where you can try it out. Kanban is increasing in popularity, @henrikkniberg had 300 people on his Kanban vs Scrum session at JAOO this week.
