I have certainly fed random inputs to sage and found some that would crash it. At least some of those bugs got fixed by the authors of the code.

The major motivation factor for open source developers is to not to make money from it. I suspect one could earn more stacking shelves at the local supermarket than on getting paid to find bugs. How would you decide which bug reports get a bounty - waste time on a vote? > and spend 10 to 30 percent of funding money for QA related tasks - > there is a rule of thumb that for three developers one tester is needed. I have not heard that, and I am sure it must depend to a considerable amount what the implications of a bug are - in systems where someone's life depends on the correct functioning of software would be different to a cheap game. I think what is really missing from Sage is "bug-fix-only" releases, where no new functionality is added - only bugs fixed. This is pretty standard for both commercial and open source software, but despite me suggesting thus several times, there has never been much appetite for it. Anyway Jakob, while I don't agree with everything you say, it is good to see someone else raise the issues of how to increase software quality. Whilst I think the signal to noise ratio from RJF is too low, his example of weather forecasting get me thinking. It must be particularly tricky in that sort of software to find bugs, when everyone knows it will not be perfectly accurate.
