Your Python Code Is UNSAFE (seriously) – GIL’s Hidden Secret
In this video, we take a deep dive into the inner mechanics of Python’s Global Interpreter Lock (GIL), which is a must for all threading and multiprocessing devs, and expose a subtle nonce / hidden vulnerability, which could potentially make your code unsafe. Join us as we explore the impact of GIL on threading and multiprocessing, and discover how it affects the performance and scalability of your Python programs. By the end of this video, you’ll gain valuable insights and learn proper threading practices that can help you avoid potential pitfalls.
