I am a software developer... I am certified (MCP) in WindowsForms.NET, ASP.NET and ADO.NET (with C#) and I really like .NET (I specially love LINQ)...

I sometimes blog at Javamexico or at my personal blogspot. I also tweet ocasionally

I also know how to code in Java (I love Hibernate,and I love Spring-Mvc but I think for the web the future is in JSF with Seam... and for SmartClients XAML... but perhaps Flex will give a good fight) , I know a little of Delphi... and I have worked with Oracle and SQLServer...

The best web technology that I have used is WebObjects (sadly IMHO Apple just doesn't seem to know its value) I think SQL is full of flaws... I used to believe the only way to go is to use an ORM and I really disliked plain ADO.NET and JDBC, I used to think that to build the business rules of a software system.. there was nothing better than Domain Model pattern... built with Apple's EOF... or Hibernate (or NHibernate or LINQ & EntityFramework). But lately, after reading TheThirdManifesto, I have been thinking that relational is not limited, it is underexploited, and perhaps Alphora Dataphor or Rel will finally exploit its power.

I am also certified in TFS 2010, and I know my way around CVS, SVN, Mercurial, Bazaar and a little Git

Maybe you could please answer this question: mathematica.stackexchange.com/questions/22798/… using this TransferFunctionModel?

Any book, website or guide you recommend on how to take a systemdynamics "graphic model" and translate it into something that can be fed in to TransferFunctionModel?

comment How do I represent a system dynamics feedback loop?
I tried with coli[20, 1, 4], and the numbers match! {1, 21, 441, 9261, 194481} but there is a mismatch with the time, 194481 is for hour 5, but in InsightMaker is for hour 4...

comment How do I represent a system dynamics feedback loop?
You are right when you say that I am looking for an implementation that's as literal as possible, the better the solution matches the diagram parts, the better it will help me understand the math behind the diagram

comment How do I represent a system dynamics feedback loop?
I am not exactly sure of how to translate "beta1", "beta2" , "delta0" and "pop0" to the diagram parts... could you please change the name of those parameters to better match the diagram parts?

I like it... But the number of bacteria in your graph does not match mine...

Thanks!, but one thing bothers me, after 4 hours the number of bacteria in your graph does not match mine...

comment Are you interested in purchasing David Wagner's “Power programming with Mathematica”?
Is there any way that this could also be used to show interest for new (updated for Mathematica 9) edition?
