OSError: Directory is not empty happening in some windows boxes

[This was originally reported by @ahendry2688 in https://github.com/Blosc/python-blosc/issues/131#issuecomment-353257366. This really belongs here.] Sorry, I meant bcolz. I did a regular pip install from the command prompt, ran `bcolz.test()` three times,...

The next code triggers the segfault sporadically: ``` import bcolz a = bcolz.ones(1e7) a.resize(2e7) ``` Not sure about the cause, but valgrind is not saying anything immediately obvious...

Implement logical operators for carray objects

That would allow the next code to work correctly: ``` In [1]: import bcolz In [2]: a = bcolz.arange(1e7) In [3]: b = bcolz.arange(1e7) In [4]: a == b Out[4]:...

Add minimum, maximum functions

_From [[email protected]](https://code.google.com/u/105358803093019457519/) on June 07, 2012 16:43:59_ It would be useful to add np.mininum and np.maximum functions. 'maximum(x-a, 0)' would be faster and clearer than 'where(x-a>0,x-a,0) _Original issue: http://code.google.com/p/numexpr/issues/detail?id=86_
