In this blog post, I will look into the implementation details of CPython’s Global Interpreter Lock (GIL) and how they changed between Python 3.9 and the current development branch that will become Python 3.13.
Mar 13, 2018: How to Design Collection Libraries?
Programming languages naturally come with a library of containers or collection types. They allow us to easily work with arbitrary number of elements, which is something all major languages care about. Unfortunately, it seems like there is not much writing on how to design such libraries. Even asking a few people that worked for a long time on collection libraries did not yield much of a structured approach to such a central element for our languages. The one major piece of writing we found is the Scala people describing their experience with bit rot and how they redesigned their collection implementation to avoid it.
Jan 27, 2015: Partitioned Global Address Space Languages
More than a decade ago, programmer productivity was identified as one of the main hurdles for future parallel systems. The so-called Partitioned Global Address Space (PGAS) languages try to improve productivity and explore a range of language design ideas. These PGAS languages are designed for large-scale high-performance parallel programming and provide the notion of a globally shared address space, while exposing the notion of explicit locality on the language level. Even so the main focus is high-performance computing, the language ideas are also relevant for the parallel and concurrent programming world in general.
