Pinecone and Chroma are a lot of machinery for a few hundred Markdown notes. The Google Memory Agent Pattern keeps structured memories in SQLite, consolidates them in the background, and loads them straight into a large context window.
Why dot product geometry matters if you build search relevance or recommendations. Unit vectors, scalar and vector projections, the shadow analogy, and a plain PHP cosine similarity function you can read.
A 7M-parameter Tiny Recursion Model beat DeepSeek R1 on the ARC-AGI benchmark by looping over the problem instead of scaling up. What that says about trading parameters for iterations.
Why the column space view of linear regression beats the scatter plot: features as vectors, the intercept as a vector of ones, and the normal equation as the point where the error runs perpendicular to the feature plane.
Most people run one Claude Code agent and then wait for it. Git worktrees let you keep several going in separate folders on the same repo. How I lay that out in Warp or Tmux, plus the shared local database problem nobody warns you about.
How I pick features for credit scoring models in Python: Kruskal-Wallis for continuous variables, Cramer’s V for categorical ones, and Spearman rank correlation to catch redundant pairs before any training starts.
Machine learning projects fail on planning more often than on algorithms. What works for me: chase approvals early, block real hours for the main pipeline, and stop repointing the stack every time a new model ships.
Notes from the Dev Chat on WordPress 7.0: the AI Client and Connectors API, why the release cycle got extended, the left navigation rethink, and the argument over YouTube support in the Cover block.
Products drift when nobody writes down what they stand for. How Dieter Rams’ principles helped me kill an upsell on a WooCommerce checkout, plus the workshop and the CSS variables I use to keep principles in the code.
WordPress 7.0 brings AI into core through the AI Client and the Abilities API. Here is what wp_ai_client_prompt() actually does, how to test it now, and what the Core AI team will work on during Contributor Day at WordCamp Asia 2026 in Mumbai.
