I see a communication glitch happened. There was a mention of creating a new organization and an offer to join, but the issue was closed simultaneously - meaning perhaps you never saw it. This seems like a surprise to you.
@philippeowagner: I think it'd be appropriate to see you both share and organization if you both intend to participate. If I was lilspikey, I'd feel my project was hijacked.
I assume good faith in you Philippe, but I don't think lilspikey knew your intentions since the issue was closed.
That's what I noticed. If you label the horizontal axis for the amount learned (more or less equivalent to his "Performance" that he has on the vertical axis) and the vertical axis for effort required, it would fit standard usage just fine.
I used Python + OpenCV during my MSc for face-detection: http://littlespikeyland.com/msc/project/ back in 2003/2004, so I ended up doing a lot of SWIG wrapping. A lot of the heavy lifting was done in C/C++, as I was running lots of simulations for a evolutionary algorithm.
I've used ctypes for a few projects now and wish I could have used it for that project. Might have meant I could have ditched a lot of the C/C++.
