Causal inference and the accuracy trap in ML
A readmission model with 94% accuracy made things worse because it found a correlation, not a cause. Where Pearl’s ladder of causation comes in, and how DoWhy’s four steps keep you honest.
Why NumPy and Pandas give different variance results
Same ten numbers, two different variances. NumPy defaults to the population formula and Pandas to the sample one. Here is what ddof does and how to set it so your pipeline and your prototype finally agree.
Why dropdowns get clipped in scrollable containers

An agent turned a missing database index into a 500-line middleware layer. What I do differently now: plan mode before any code, core WordPress functions first, and a read through the tool calls rather than just the final file.
Build a Navier-Stokes solver in Python from scratch
A walkthrough of writing an incompressible Navier-Stokes solver in Python with NumPy: momentum and continuity, finite difference discretization, the Pressure-Poisson step, and airflow around a wing.
Pattern overrides in WP 7.0 now work with custom blocks
WordPress 7.0 lets any block that supports Block Bindings take part in Pattern Overrides, not just the old Core list. You opt a custom block in with the block_bindings_supported_attributes filter.
Personalized restaurant ranking without the popularity trap
Popularity sorting puts the same big chain at the top of every shelf. A lightweight two-tower embedding setup, with a frozen TinyBERT on the item side, ranks restaurants by what the user is browsing for.
