Project mention: How to Get Started with Scikit-Learn: A Beginner-Friendly Guide to Machine Learning in Python | dev.to | 2025-04-24
As is the case with most Python libraries, it is open-source and free-to-use, making it easily accessible by anyone willing to learn machine learning, and it is built upon other open-source libraries within Python, like SciPy for advanced scientific operations, NumPy for efficient numerical computations, Matplotlib for data visualization, and Cython for increased efficiency and speed, similar to that of C/C++.

I hope that one day we have a tool that can convert any proprietary binary to source code with a single click. It would be so much fun to have an "open source" version of all games. Currently, there are projects like https://github.com/Try/OpenGothic and https://github.com/SFTtech/openage, but these require years of community effort.

Project mention: Qutebrowser: A keyboard-driven, Vim-like browser | news.ycombinator.com | 2024-12-08
See https://github.com/qutebrowser/qutebrowser/issues/8389 - unfortunately there's a lot of stupid false-positives especially with PyInstaller (packaging a Python application into an .exe). Happens a few times a year, unfortunately there isn't much I can do other than submitting a report to Microsoft and hoping they'll react ¯\_(ツ)_/¯
