A new year is a good excuse for a new post, even if meaningless. Let me tell you the truth: just an excuse to try wptogo, the blogging tool for Android.

Yesterday I did my “OSGi in the Enteprise” presentation, and it is already available on Slideshare.

A lot to things to figure out yet: how to organize my time, without strict deadlines and clear requirements, and avoid to waste time surfing the net (and playing Farmville ). And how to market my ideas, demos and company.

A lot of new stuff, interesting stuff though.

In my (copious) free time I started developing an OSGi Rest console. Not sure the news deserve a line in my end-of-summer updates, but it has already been used by Toni and Sahoo.


No, I still haven’t learnt German. But I enrolled in my fourth language course at the end of August.


Went regularly to the gym. One every two weeks.


Spent my 5 days summer vacation in Cagliari. A lot of achievements there:
– ate snails for the first time in my life
– ate oysters (with lemon) for the first time, and thought that they taste of lemon too much (go figure)
– presented Spring DM: where OSGi meets the Spring Framework at the Spring Framework Italian User Group
– wandered through the city with magomarcelo

You can find my review on the OSGi Look. ]]> http://diotalevi.com/2009/08/13/modular-java/feed/ 0 http://diotalevi.com/2009/08/02/the-osgilook-linode-and-minor-migrations/ http://diotalevi.com/2009/08/02/the-osgilook-linode-and-minor-migrations/#comments Sun, 02 Aug 2009 21:20:58 +0000 fildiotalevi http://diotalevi.com/?p=55 Six months after the first post, I felt it was about time to give the OSGi Look a better shape. The blog, started just as a collection of links to OSGi-related news and posts, is starting to have a small but growing number of followers, especially since I started to post some original contents.
What better excuse to get a shiny new virtual private server?

After the good experience with Slicehost I was very keen to get another “slice” with them, but their signup procedure refused to create me an account. In fact I couldn’t log in into Slicehost with my previous account anymore, that was blocked when I canceled my “slice” subscription a few months ago; and I wasn’t able to create a new one, since the system insisted that I couldn’t create a new account with my email, as it was already associated with another account.

Being too lazy to write an email to the support, I just decided to give a try to Linode, which happens to be 10$ cheaper.

So far I’m quite happy with linode. The latency is probably a bit higher than slicehost, but overall very acceptable. And it’s nice to have again a vps!

To cut the long story short, the OSGi Look is, since yesterday, happily running in my Ubuntu virtual server. I gave it a new design, and I have a few ideas to enhance it. In the next few weeks I hope to migrate there also this website and my company one, that are currently hosted by Servage.

In any case, here’s a list of the most interesting developments in the OSGi world:

• R4.2 is coming, and with it the Remote Services specification (Eclipse ECF and Apache CXF are the first implementations). With Remote Services OSGi won’t be considered (finally) just “SOA in a JVM” anymore, but a real distributed technology; another step toward the real Pervasive OSGi.
• The Blueprint Service specification will standardize the dependency injection mechanism proposed by Spring DM
• The “Enterprise Edition” of OSGi will come next year, bringing more interoperability between Java EE components and OSGi
• The “Provisioning war” has officially started with the presentation of Apache Ace and Eclipse P2
• Mobile OSGi is coming, and more and more companies are working on that; Sprint Titan, Prosyst and Luminis are paving the way, but something is moving also in the open source arena

On a personal note, OSGi Devcon has also represented a turning point, since it was the first event I could hand out business cards of my OSGi consultancy, and my first OSGi conference after being elected Apache Felix committer.

So, a lot of things going on!

All of that, without any clear direction (architecture?): a few chapters reminded me of some of the more abstruse and theoretical academic papers (see f.i “What is Architecture?” and “Object Oriented Versus Functional”), some others go into the low details that honestly I wouldn’t expect in an architecture book.
I’d save just a few chapters: “Data Grows up: The Architecture of the Facebook Platform” and the first part of “When the Bazaar sets out to build Cathedrals” (about KDE history). Probably just 30 out of 400 pages, obviously not enough to recommend this book.

The Swiss city in fact will hold the OSGi Devcon Europe conference, that runs in parallel with Jazoon. After attending many big conferences like Devoxx, Jazoon, Apachecon, I’m really looking forward this small conference. So many things are happening in the OSGi world in these days, and such a small-focused event is ideal to meet all the developers involved. Some of the topics: Distributed OSGi Persistence with OSGi Blueprint service (standardization of dependecy injection a-la Spring DM) Provisioning with Eclipse P2 Provisioning with (the upcoming) Apache Ace Scala & OSGi

Of course I’ll take the opportunity to walk around the city and take some pictures. Last time here, two years ago, I found an extremely hot weather (but I didn’t bring my camera with me). Hopefully I’ll have some picture to post next week.
