Hey all, Guido just formally accepted PEP 465: https://mail.python.org/pipermail/python-dev/2014-April/133819.html http://legacy.python.org/dev/peps/pep-0465/#implementation-details Yay. The next step is to implement it, in CPython and in numpy. I have time to advise on this, but not to do i

[Numpy-discussion] Proposed new function for joining arrays: np.interleave

Hello, Interleaving arrays is something I need to do every now and then, and by the looks of stackoverflow so do others: http://stackoverflow.com/questions/12861314/interleave-rows-of-two-numpy-arrays-in-python http://stackoverflow.com/questions/5347065/interweaving-two-numpy-arrays I think the

[Numpy-discussion] ANN: numexpr 2.4 RC2

=== Announcing Numexpr 2.4 RC2 === Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It wears mu
