This week, one of the most talked about things is a weird video of a person who seems to have a real hoverboard equipped with a jet engine. The video was published by Zapata Racing, which released water versions of these aircraft for several years. The difference is that they have always been tied to some kind of personal watercraft. This new Flyboard Air, as CEO Frankie Zapata calls it, is something completely different.

Some dictionary internals in CPython (and PyPy)

Some dictionary internals in CPython (and PyPy) 3r3407. 3r3-31. The internal structure of dictionaries in Python is not limited to bucket and closed hashing alone.
