Yttrium Diagramming
30 März 07 03:44 | Christoph Rüegg | 1 comment(s)

There was quite a huge check-in lately on the yttrium source code repository. I've been refactoring the yttrium code base to a new microkernel based architecture (motivation: getting rid of cyclic dependencies and the high degree of complexity). The most striking change is the number of assemblies: Instead of a single dll the project is now split in multiple modules & services.

I'm also working on the diagramming frontend Whiteboard again. As you may have noticed, François is back working on Diagramming. Although he's finally moved forward towards WPF/.NET3 with his new Unfold project, he also released the older GDI+/.NET2 based Netron 3 code to the public (GPL; thanks, François!). I'm currently porting Whiteboard to the newly refactored yttrium codebase and extending the Netron code to better match the yttrium model. It looks great so far, keep in touch. Btw, I also include adjusted shapes for the new PetriNet demo package.

Iridium Release 8: 2007 March (v2007.3.8)

I've just released a new version of the C# Math.NET Numerics toolkit Iridium, v2007.3.8. Grab it here.

What's new in this release?

  • Completely revised FFT implementation
  • Integration of the Torschutz Random Library, revised and extended with pdf/cdf functions.
  • Various minor enhancements and fixes

I allowed myself to include some breaking changes; you'll have to update your code if you're working with either FFT transformations or with probability distributions and random generators. Nevertheless, I still recommend to upgrade, as I don't expect breaking changes in this extent (if any) in the next few releases.
