Distributed Reflections of the Third Kind

It’s final. Three years ago, I moved from Sun hosted Roller to self-hosted WordPress. But I am done with it. WordPress may have loads of features - I only care about some of them, and I want to get rid of my server at LunarPages.com.

Blogger seems to be quite ok. And more importantly, it allows you to have your blog hosted at your own domain, which is one of the reasons I started considering it in the first place.

In a way, to me, it marks the end of an era. Instead of buying computational power, I ‘buy’ the services (note that I don’t actually pay for it). I aim to buy computational power only if I need it, through cloud computing services, which is getting fairly simple these days.

The location of my blog will also move, so if you feel like updating links, this would be a good time. The new location is http://blog.flotsam.nl/. Flotsam.nl is a domain I acquired last year. My new email address is [my first name]@flotsam.nl.

A picture not included in the documentation. Added here to get a better understanding of the difference between good old Spring and Spring ME. Note that purple is ‘at build time’.

It’s finally there. A couple of months ago, I decided to scratch my itch, and work on a dependency injection framework for Java ME. I know many people tried it before I did, and I was aware of the limitations on Java ME that would make it hard to port Spring to the phone.

However, I figured that if you do all of the analysis at build time, and if you also build a BeanFactory geared specifically at your needs, it should be possible.

We have been working with it for quite a while now, and TomTom decided to put it out there, for the benefit of everyone.

Now, we did not cut a final 1.0 release yet. First of all, because some bits of the API are a little - uhm - akward, and we the unit test coverage is not very high yet. However, the current incarnation is proving to be quite usable already.

Below, you find a small introduction into the framework. The PDF document can also be downloaded through http://springframework.me/.

Spring ME

You can download a first distribution of Preon here. It does not include the examples yet, but it does include the libraries, Javadocs, manuals and all other required libraries. Have fun!

Will talk about Preon at Devoxx on Tuesday:

A couple of days ago, I published an “Under the Hood” chapter of a Preon manual… You might actually have been interested much more in just getting a simple introduction. In case you did, I’m happy to announce that I’ve just (sort of) completed an introduction.

Preon Introduction

Preon is now supported by FishEye and Crucible. Check it out, here:

Technorati labels: preon, java, fisheye, bitstream, decoding

Last Wednesday, I presented Preon to an audience of Java developers. Digging around in the sources, I found out that I started to write a document on Preon ages ago. I brushed it off a little, and posted it to Scribd. Find the pre-publication here:

Preon Under the Hood

I just created a Google group on Preon, a minute ago, open to anyone. Preon is a framework for binding your Java classes to bitstream encoded data, comparable to what Hibernate is to relational databases, and JAXB to XML.
