Mean imputation and unclipped outliers are what break credit risk models. This covers splitting first to avoid leakage, IQR clipping with training-set bounds, and what to do when the missingness itself is informative.
Manually reassigning object properties is a habit worth dropping. Array and object patterns, nested REST API responses, and rest properties, with the WordPress and WooCommerce cases where each one saves you lines.
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.
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.
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.
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.

Prompt caching gets all the attention while the expensive work happens before the model sees a token. Five places to cache in a RAG pipeline, from query embeddings to full query-response pairs, with a transients example for WordPress.
