Notes on building a data-driven goal tracker with Python, Streamlit and Neon: one schema for daily habits and quarterly milestones, ISO-8601 week boundaries so the weekly numbers do not drift, and a REST API bridge when the data has to land in WordPress.
Notes on porting statistical models into WordPress: where research gets diluted instead of distilled, how real-time aggregates in user meta leak data through race conditions, the atomic SQL fix, and why a bigger LLM is the wrong answer to arithmetic.
A knowledge graph has three layers: an ontology, controlled vocabularies and observational data. This post walks through what each one does, and shows the WordPress version of the shift from flat meta_query lookups to taxonomy-based entity relationships.
Retrieval-augmented generation is past the demo stage. Notes on chunk size as an experimental variable, why HNSW precision degrades as the index grows, the latency cost of extra retrieval layers, and a transient wrapper for caching retrieval in WordPress.
A multi-agent Autogen loop running Mixtral 8x7B locally on an M3 MacBook rewrote a Rust matrix multiply until it hit NEON SIMD and Rayon, taking it from 760ms to 359ms. Notes on how the loop was set up and where the generated code went wrong.
An L40S idling a full second between batches is a data transfer problem, not a compute problem. How multi-worker output processing, pre-allocated pinned buffers and dedicated CUDA streams took one PyTorch inference pipeline to about 4X throughput.
Poisoned training data does not crash anything. It shifts your model’s weights while the accuracy score stays high. Who does it and why, from malware authors to artists using Nightshade, plus what a sanitization layer on your ingestion path needs to check.
The code block was a glorified textarea until WordPress.com rebuilt it. Native highlighting for over 100 languages, copy buttons and line numbers in the sidebar, and syntax token colors you can set from theme.json instead of loading Prism.js on every page.
RGB alpha blending averages channels, so background color stays baked into the edges of every cut-out. Moving the operation into Lab and deprojecting the chroma vector removes the spill, and a three-tier mask fallback keeps the pipeline running when a model chokes.
Databricks and Snowflake are running into a market ceiling while the fees to connect your own data keep climbing. Why WooCommerce reporting is usually better off staying in WordPress, on lean SQL and a WP-CLI command.
