GIL (Global Interpreter Lock) is a mechanism in CPython to synchronise the Python bytecode execution to run only in a single thread at a time. It constitutes a straightforward CPython implementation but becomes obstacles of parallelism in Python. Retrospective endeavour in removing GIL did not reward well. Most of the... [Read More]

Following with the previous article, I tested further a few more cases to benchmark the runtime performance on various JIT compilation libraries (Numba, JAX, TensorFlow and PyTorch). In this time, I am going to test with a more realistic example used in machine learning and numerical computation - linear regression.... [Read More]

It has been a while I haven’t looked into the current development of Python compilers of which improves the running time of critical paths, e.g. in quantitative finance / scientific research, in the application. There are much more libraries tackling the problem, either by bridging the original CPython C extension... [Read More]

Recently I have read a great article called “Software Engineering at Google”. There are many points inspiring me on software development principles. Actually these applies not only on software engineering, but also, I believe, on running a successful business. [Read More]
