Many of you have been using simd-cxx v0.x for productively hacking DDS code. Some of you, are probably aware that simd-cxx v0.x has been the main driver behind  the recently adopted OMG DDS-PSM-C++  standard -- in essence the new C++ API for DDS.

If you like simd-cxx v0.x be reassured,  you’ll love the new standard and simd-cxx v1.0 (http://github.com/kydos/simd-cxx) -- its Open Source implementation for OpenSplice DDS

In my last blog post I reviewed the Open Source definition from the Open Source Initiative. Today I will tackle the “Free Beer” vs. “Free Speech” aspect of Open Source and  debunk some common misconceptions.

I thought that most people in the software business understood what Open Source is and when Software can be defined as Open Source. Recently, I was struck to see a company calling Open Source something that it really is not. To tell you the full story, they have even coined the term “Open Source 2.0” – perhaps in an excess of marketing creativity? This poses the question of "when is Open Source genuinely Open Source"? I am still puzzled trying to understand why this was done. Was it genuine ignorance? Intentional confusion?  I anticipate this stunt is going to be critically judged by the open source community.

While waiting for this judgment, I felt it would be useful to summarise what genuine Open Source is and when software can be defined as Open Source.

First of all I want to whish all of you a very Happy, Healthy, and Peaceful 2012.

I am just back from a week-long business trip in India. Perhaps the best way to get great inspiration for starting this brand new year.

With OpenSplice v6 we have introduced several different new features but there is one in particular that I've been wanting to cover  for some time. Tonight, once dinner was over (very good vegetarian variation of the Risotto alla Milanese which I cooked myself) and kids were in bed I was about to begin my evening Yoga when I had this funny feeling -- had I become a Fimble? Not as far as I  could tell, but at the same time I  felt that before devoting myself to Yoga I had to write about this one thing.

So what is it?

Escalier provides a Scala language binding for DDS currently targeting the Open Source DDS implementation OpenSplice. The beauty of Escalier is that it takes advantage of the nice features provided by the Scala language (check out the Scala web site for tons of good documentation on how to get started with Scala)   to provide a very concise and elegant API for DDS.

Something I've been writing about for some time is the relationship existing between Stream Processing Systems, DDS and CEP. Below, I'll provide a short introduction of they key concepts behind Stream Processing and then show how you can use OpenSplice and Esper in combination as the your foundation for Stream Processing Architectures.

While attending a workshop, a few weeks ago, I came across a great presentation, from Sveta Shasharina, TechX, highlighting several great  use cases of OpenSplice DDS in scientific applications. Beyond being pleased by hearing how many scientific projects are using OpenSplice DDS, I was definitively amused by the scale and complexity of some of those, such as the Large Synoptic Survey Telescope.

As this is public information, I've asked Sveta to share the slides with the community and I've posted them on slideshare and embedded below for your convenience.

Those of you who know me, are well aware of my passion for Jazz, yet this blog entry is not about the beautiful "Take Five" the 5/4 masterpiece written by Paul Desmond and performed by The Dave Brubeck Quartet in their Time Out (1959).  This entry is about the 5 vendors DDS interoperability demonstration that took place today in Washington DC, during the OMG Technical Meeting.

Today, at 14h00 US Eastern time, PrismTech (OpenSplice), RTI, IBM, TwinOaks and Gallium joined up to demonstrate the interoperability between their respective DDS implementations. The scenarios that were demonstrated spanned from basic discovery and interoperability with default QoS, to the demonstration of QoS negotiation, filtering, failover, etc.

I am back to Paris after two days in of ATC Global in Amsterdam. These have been two very busy days spent presenting and discussing, with the many of you that came to visit our stand, the Blend-Box,  DDS, and OpenSplice DDS -- Thanks very much for coming so numerous!

Now, getting back to ATC Global, one of the things to highlight were the very nice CoFlight demoes that were given by THALES and SELEX-SI. The CoFlight Program, headed by THALES,  SELEX-SI, DSNA, ENAV and Skyguide, has been developing in the past few years the next generation flight data processing (FDP) system, which fully in line with the SESAR objectives, will reduce the environmental impact of aviation, improve flight cost efficiency, and optimize the  airspace usage. After several years of R&D CoFlight is getting closer to the first deployment phases:
