How fast can we generate a new release?

My journey in poetry, conventional commit and semantic release

Posted on November 29, 2022

Working in open source projects is fun, but it may also mean to sacrifice one’s personal time to transform amazing ideas into applications. Down the road of development, tedious and routine works are definitely involved. A colossal amount of chores, e.g. documentation, building distributions, and releases, are demanded to keep...

How far is it now to get rid of GIL in the future Python?

Posted on October 3, 2022

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]

Python Compiler Comparison (2)

Compare with various JIT compilation libraries - Numba, JAX, Tensorflow and PyTorch

Posted on August 27, 2022

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]

Python Compiler Comparison (1)

Cython, Numba and JAX

Posted on July 13, 2022

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]
