When to choose checked and unchecked exceptions
...n what layer the caller of your API is located.
Let's say that I create a StringToInt API that converts the string representation of an integer to an Int. Must I throw a checked exception if the API is called with the "foo" string ? Is it recoverable ? I don't know because in his layer the caller o...
Numpy `logical_or` for more than two arguments
... no, as the docs explicitly say, the only parameters are x1, x2, and optionally out:
numpy.logical_or(x1, x2[, out]) = <ufunc 'logical_or'>
You can of course chain together multiple logical_or calls like this:
>>> x = np.array([True, True, False, False])
>>> y = np.a...

Example A. 5/(-3) is -1
=> (-1) * (-3) + 5%(-3) = 5
This can only happen if 5%(-3) is 2.
Example B. (-5)/3 is -1
=> (-1) * 3 + (-5...

What is an OS kernel ? How does it differ from an operating system? [closed]
...ernel is an operating system in that sense.
The end-user definition is usually something around "a software package that provides a desktop, shortcuts to applications, a web browser and a media player". A kernel doesn't match that definition.
