WordPress Studio Xdebug and the new debug log toggle
WordPress Studio added Xdebug support and a dedicated debug log toggle. Here is how I turn both on, the one-site-at-a-time catch, and the port your IDE has to listen on.

PythoC: compiling Python down to native binaries
PythoC compiles a subset of Python into standalone native binaries through LLVM. My notes on the 40x Fibonacci run, the print() that produces nothing, and the cases where a native compiler is the wrong tool.
Building synthetic training data when none exists
Real test data is usually missing right when you need it. How I generate varied synthetic WooCommerce orders with an LLM, and the two ways it goes wrong: context rot, and only ever prompting for the happy path.
Why your RAG pipeline still misses exact keywords
Pure semantic search stops finding part numbers and SKUs. Why I pair embeddings with a BM25 keyword index, what the k1 and b parameters change, and how rank fusion merges the two result sets.
Real-time collaboration: why your meta boxes break it
WordPress 7.0 syncs the block editor through Yjs, and one classic meta box switches the whole thing off. Migrating meta to the REST API, swapping HTTP polling for WebSockets, and the block side effects that fire for every editor in the session.
What WooCommerce 10.6.1 actually fixes
The Add to Cart with Options block compared hyphenated slugs against labels with spaces, so variable product selections failed validation. WooCommerce 10.6.1 fixes that, reorders new payment gateways, and drops the stray number from single shipment labels.
Why your data stack is not ready for AI agents
Dashboards are no longer the main consumer of your data. Here is what I would change in a data stack to make it readable by agents: fewer tools, open table formats, a real semantic layer, and feedback loops that act without waiting for a human.
Fourier transform sound analysis without the black box
np.fft is not a black box you have to live with. This walks through the winding machine picture of Fourier transform sound analysis, the center of mass calculation behind magnitude and phase, and why Euler’s formula shows up instead of a plain sine wave.
Metropolis-Hastings, or how to sample without the integral
Bayesian work hands you densities you cannot integrate or invert. Metropolis-Hastings samples them anyway, with a random walk and an acceptance ratio that cancels the normalization constant. Includes the NumPy implementation and the three ergodicity conditions.
WordPress 6.9.4 fixes what 6.9.2 and 6.9.3 missed
WordPress 6.9.4 re-applies three security fixes that 6.9.2 and 6.9.3 left incomplete: PclZip path traversal, XXE in getID3, and a Notes authorization bypass. It also covers the WP-CLI commands I use to update core and check the files afterwards.
