Comment: C: C++ tools are hard to install for biologist, why the community stick on it?
... I strongly agree with Rob's comment about the great control over memory coming with c++. Moreover, I am not sure at 100% that java takes advantage to use specific hardware features as SSE registers for instance (which allows to vectorize some algorithms with great speedups) Note that I am a great ...
