open software

Peter Dunkelberger on

Hi Rob,

A little while ago I read that the software for Bivio is "open". I was wondering what that meant for users (club treasurers and members). For instance, I would like to see how the IRR reports are prepared. Is it possible to see the software for that report/process? Would I know what I was looking at if I did see it?

Thanks for any feedback.

Hi All,

Bivio is now an approved Schwab third party vendor. We have begun testing our software against theirs.

Our current estimate is that it will be production ready in two weeks. If you are interested in being a beta tester, please email support@bivio.com.

Thank you for your patience.

Cheers,
Rob

I would be interested in being a beta tester for the Bivio program. I have been using for about 20 years.

Thank you for your question. While much of the Bivio software is open source, the core accounting is not open source. The proposal in the summer was to open source our software so that we could get help from community programmers by turning Bivio into a not-for-profit. That met with a resounding "no" from the community, and instead, we are continuing to operate Bivio as a commercial company.

As to your specific question, I doubt you would get much out of looking at the IRR calculations. I can tell you it is based on an algorithm in Financial Numerical Recipes in C++ by Bernt Arne Ãdegaard, which was based on the original Numerical Recipes in C. Our algorithm is programmed in Perl, and contains some complexity involved in the database queries and the IRR Wait Period so it's more complicated that these implementations.

Cheers,

Rob

Thanks very much. Rob. I appreciate your quick response. I might look at Financial Numerical Recipes.
