WordPress wants to build Block Editor Handbook pages straight from block.json at build time. That would kill doc drift and give core blocks a reference that matches the code you are actually running.
Utility software gets designed to be invisible, which is why people resent it. Linear, Vercel and MacPaw treat the maintenance layer as something a person actually sits through, and it shows.
Ridge, Lasso and ElasticNet land within 0.3% of each other on prediction accuracy, but Ridge fits eight times faster and Lasso’s feature selection falls apart once features are correlated. Three numbers tell you which one to fit.
Saturation is a correction tool, not a volume knob. How CSS saturate() actually paints, why the order you chain filters in changes the result, and the stacking context backdrop-filter quietly creates.
Manual regression testing was my bottleneck, so I automated it. This covers wp-env setup, Playwright with the WordPress test utils, and testing block variations and meta bindings without clicking through the editor.
Hard-coded constants assume a perfect environment. This covers four ways to model uncertainty, from robust optimization to two-stage recourse, and refactors a fixed cron batch size into one that reacts to load.
Notes on using the CSS contrast() filter in WordPress themes: how the RGB math works, why it beats a black overlay on hero images, a 125% hover fix for washed out product cards, and where filters get expensive.
CSS has a hypot() function that does Pythagorean distance math and, unlike pow(), accepts units like px and rem. I cover what it returns, a cursor-proximity example using container style queries, and the edge cases worth knowing.
One ballot label counted as two parties made English local elections look like they were splintering. The fix was normalizing party families before aggregation instead of after, and the headline finding reversed once we did.
Fixed-height cards look tidy in a mockup and fall apart when an editor doubles the copy or a translation runs long. I go through what breaks, and how Flexbox and intrinsic sizing hold the same grid together without hard-coded heights.
