Prigogine did not share his Nobel with anyone.

Quants aren't good because they are great programmers. just as there are no new models, there are no new architectures- they are slotting code into an existing code library. adding a new payoff in quantlib is not the same as designing quantlib.In the beginning, application Functionality is important, then maintainability (stability, changeability etc.) become crucial. How to make it happen is an important issue.

QuotePrigogine did not share his Nobel with anyone.indeed Kat, to be more precise Prof. Nicolis was co-heading the ULB/IRM research team when the Nobel was given, however, the award was only given to Prof. Prigogine indeed. Regardless, they have published really great stuff on irreversible thermodynamics, back in the time there was still a scientific field called physical chemistry, paving the way for the studies of complexity and non-linear phenomena. Luckily enough, we happened to have worked under their guidance back in 96/97/98. Good times.

Is it for the problems with threads? Over-engineered?

No one knows it well enough to provide constructive feedback, because its far from obvious and takes time to learn. Saying it has been overengineered is a serious misunderstatement in the GWBush sense of the word. I do like qlib and qlnet and learnt a great deal therefrom.

I was reporting what I heard people saying. I think it'd be useful to hear also constructive negative comments, tho.

Devon, do you know what happened to qlnet? It seems the port has been discontinued and SWIG suggested as a solution, but I never really understood why.

I think if these libs were documented then - despite the complexity of the design (tight coupling) - developrs coud be writing applications in a shorter period of time than is now the case. I am only the messenger.Some constructive remarks for upgrades imo here "It'd be nice if the developers set up a wiki so that we all can contribute documentation to whatever part of the system we are familiar with. Look at wikipedia!"

The overall atmosphere here seems to imply best preparation for becoming a quant is at least a BSc in computer science coupled with some finmath degree, doesn't it?I'll never be a "quant" then, but that's fine, job title is not what is important ;-)

Thanks for those links Polter! Printing them out right now. I have seen this problem emerge time and again in various places I've worked. No one questions the code and then they're surprised months later when there are errors. One firm had a model running for six months before they realized that the signals weren't updating properly!! Even funnier is that the model was doing well, hahaha!
