Things are moving so fast. We have now experienced working with Mathematica 8 since Nov-2011. At work we were inspired to thinking into new directions, like the combination of Mathematica 8's most comprehensive statistics and probability solvers and functions and our machine learning framework devotes to econometrics problems, or look deeper into econophysics studying pricing formation of financial instruments and the behavior of underlyers.
Financial risk management has already forced us to drive CUDA over the Grid in UnRisk.
On 6-Oct-11 we will present our and others experiences at the Austria - Mathematica Conference 2011 in Vienna.
The conference is packed with tips, tricks and techniques from developers and experts who have developed hundreds of thousands of lines of Mathematica code in hybrid environments with C++, Java, SQL, Web Services, ...
