What are good uses for Python3's “Function Annotations”
...re what you make of them.
They can be used for documentation:
def kinetic_energy(mass: 'in kilograms', velocity: 'in meters per second'):

They can be used for pre-condition checking:

How do I create an average from a Ruby array?
...
Try this:
arr = [5, 6, 7, 8]
arr.inject{ |sum, el| sum + el }.to_f / arr.size
=> 6.5
Note the .to_f, which you'll want for avoiding any problems from integer division. You can also do:
arr = [5, 6, 7, 8]
arr.inject(0.0) { |sum, el| sum + el } / arr.size
=> 6.5
You can define it...
What does the restrict keyword mean in C++?
...h the time.
Edit
I also found that IBM's AIX C/C++ compiler supports the __restrict__ keyword.
g++ also seems to support this as the following program compiles cleanly on g++:

return *a + *b;
}
int main(void) {

I could not however find a function to classify if a NaN is sNaN or qNaN, so let's just print out the NaN raw bytes:

How to get the parent dir location
...bspath doesn't validate anything, so if we're already appending strings to __file__ there's no need to bother with dirname or joining or any of that. Just treat __file__ as a directory and start climbing:

os.path.abspath(__file__ + "/../../")
That's far less...
Can local storage ever be considered secure? [closed]
I'm required to develop a web application that will function offline for long periods. In order for this to be viable I cannot avoid saving sensitive data (personal data but not the kind of data you would only store hashed) in local storage.
