Learn how to program with a guitar...instead of a keyboard. Using some custom Python code and some other plugins, the autor has created something that turns the raw guitar signal into key strokes. What does programming Python sound like on the guitar? When can you throw away your keyboard for something like this?

In this post, we’re going to reduce the complexity of using gRPC by writing a shared library in Go that a Python program can consume directly. With this approach, there’s no networking involved and depending on the data types, no marshalling as well. Out of the several approaches of calling functions from a shared library in Python, we decided to use Python’s ctypes module.

This post shows how to flatten down that abstraction tower into something practical with a bit of engineering elbow grease, and come up with wait-free alternatives to the usual lock-free hazard pointers that are competitive in the best case. Blelloch and Wei’s insight that hazard pointers can use any wait-free atomic memory-memory copy lets us improve the worst case without impacting the common case!
