PodClip was built over a weekend with Replit: Spotify OAuth, Whisper transcription, Postgres. The scaffolding held up. The Spotify playback limits and the transcription costs are where a human had to step in.
Agentic loops fail quietly: the same query retried with new wording, retries with no circuit breaker, a context window full of raw JSON. Three patterns, how to measure them, and a PHP budget gatekeeper.
WordPress Playground MCP connects Claude Code or Gemini CLI to a Playground instance running in your browser. The agent reads files, runs PHP and queries the database itself, which cuts out most of the copy-paste during plugin testing and debugging.
OpenAI prompt caching takes 90% off repeated tokens, but only for prefixes over 1,024 tokens and only when the static part of your prompt comes first. Here is a Python example plus the ordering mistake that kills cache hits.
How to linearize a nonlinear objective with piecewise linear approximations, keep the segments adjacent using SOS type 2, and hand the result to an ordinary LP/MIP solver like Gurobi.
Most agencies build their own stack and end up debugging Nginx instead of shipping. What plugin bloat really costs, and what Encircle Technologies changed when they moved to managed hosting.
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.
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.
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.
