Why analytics reports come back slow and wrong, and why the fix is structural: the three modeling stages, the move from write-optimized OLTP like WooCommerce to read-optimized OLAP, the star schema, and SCD Type 2.
Hidden Gem Animal Rescue moved off social media and onto a WordPress.com hub, then doubled its pace and saved more than 100 animals in three years. What changed technically: one place for foster applications, adoption forms and donations.
Big-bang redesigns of legacy systems usually end in a blown budget and a broken database. What works instead: mapping dependencies, measuring the slow paths, and choosing a migration strategy that keeps production up.
Churn is not a yes or no question, it is a question of when. This covers censored data, Kaplan-Meier curves, and Cox hazard ratios in Python with the lifelines library.
The View Transitions API is Baseline now, so smooth page transitions in WordPress no longer need a PJAX library. Includes the opt-in rule, four CSS recipes, and the race condition that makes them look janky.
Claude Code is not only for refactoring PHP. Three things I run through it that never touch a codebase: LaTeX decks kept in Git, cross-app search over Slack and Notion, and prospect research.
Woo ran a Bug Blitz: support engineers with Claude Code and Copilot shipped over 170 fixes across 20 products, every line reviewed by quality engineers. Why it worked and what to copy.
Matplotlib draws a smooth curve as hundreds of straight segments. Orthogonal distance fitting fits Bezier curves to the same function instead, so a chart that shipped as 250+ segments comes out as two.
LLMs forget your stack the moment you close the tab. Here is what actually sticks: a project rules file in the repo, global rules for your own preferences, and MCP when the assistant needs data from outside the codebase.
Most Pandas code I inherit is a trail of df_filtered, df_2 and final_df_v2. Method chaining with assign() and pipe() turns that into one pipeline you can read from top to bottom.
