Vincent D. Warmerdam·36wdev-requirements.txt is bad
Python projects should name development requirements files as 'requirements-dev.txt' instead of 'dev-requirements.txt' to maintain visual grouping with production requirements files. This naming convention keeps related dependency files together in directory listings, making them easier to spot and manage. While functionally identical, proper naming improves code organization and reduces the risk of overlooking development dependencies.

The Palindrome·36wCorrelation vs. cosine similarity
Explores the key differences between Pearson correlation and cosine similarity, two statistical measures for quantifying relationships between variables. While both are based on dot products, correlation performs double normalization (mean-centering and variance scaling) while cosine similarity only normalizes by magnitude. Through mathematical explanations and Python simulations, the post demonstrates that these measures can yield dramatically different results depending on data scaling and offsets. Correlation is recommended when measurement units are arbitrary or different, while cosine similarity is preferred when variables share meaningful units, particularly in machine learning applications with vector embeddings.
