Python's Global Interpreter Lock or GIL, in simple words, is a mutex (or a lock) that allows only one thread to hold the control of the Python interpreter at any one time. In this video course you'll learn how the GIL affects the performance of your Python programs.

The RPython blog offers insights, tutorials, and updates on RPython, a subset of the Python programming language designed for writing interpreters and virtual machines. Developers can learn about RPython features, optimization techniques, and applications in building programming language implementations. Additionally, the blog covers topics such as JIT compilation, garbage collection, and static analysis using RPython, providing resources for compiler and language developers.

The Global Interpreter Lock (GIL) in Python is a mutex that ensures only one thread can control the interpreter at a time, posing a potential bottleneck in CPU-bound, multi-threaded programs. The video course explores how the GIL affects Python program performance and offers strategies for mitigation. The course includes 8 lessons, downloadable resources, transcripts, a Q&A session with Python experts, and a certificate of completion.
