The interesting thing about the list to me is how many of these applications are written in C++ and one or more other languages. There is a certain monotheistic outlook by most developers, and I fear this list does nothing to help it. Everyone knows the merrits and use of C++, surely its not in doubt, but to suggest that its the only solution is frankly silly. An example plucked from the list that intreged me is Sophis, the risk system. The reason is more and more of these systems are been made in Java or .Net, in fact Sophis itself is using more .Net internally with every new revision. The reason being that performance issues are normally far more related to the algo than the language, having a mixture of functional bits thrown in helps the dev make a leaner algo. Mixing such paradigyms is just easier in .Net than C++.
