A Bit Overcomplicated

Supporting half-precision floats is annoying

I just added half-precision floats to Futhark, as the type f16. This wasn’t particularly hard (perhaps a day of work), but it was annoying for fairly shallow technical reasons, so as a bit of catharsis, here’s a blog post about the challenges I encountered.

The unknown features of Python's `operator` module

At the first glance Python's operator module might not seem very interesting. It includes many operator functions for arithmetic and binary operations and a couple of convenience and helper functions. They might not seem so useful, but with help of just a few of these functions you can make your code faster, more concise, more readable and more functional.
