I am currently working with the EA on their check for flooding team. I have been tasked to look at the 5 day river level charts with a view to add more historical data. This meant increasing the amount of data showed on the chart so users could compare the current river levels with the previous week, month or year. In order to proceed with some user research I needed to create a prototype of the r
In March 2024, Google replaced First Input Delay with Interaction to Next Paint as an official Core Web Vital. FID is gone. INP is what matters now — and most React apps that were passing before are failing under the new standard without anyone realizing it. FID measured how long the browser took to respond to the very first user interaction on a page. Click a button, FID measures the delay before
We've been there. JSON Schema gets hard to write as soon as your payload is non-trivial. Conditional logic, cross-field rules, business invariants, and at some point we stop writing contracts at all. We go code-first, generate the schema from annotations, and end up with 200 lines very few understand, and error messages referencing paths like #/properties/items/allOf/0/then/Then that map to nothin
Release Date: May 20, 2026 — The most anticipated WordPress release in years is almost here. Let's explore everything you need to know before it lands. WordPress powers over 43% of the web. That's not a typo. Nearly half of every website you've ever visited runs on this open-source CMS. And yet, for much of 2025, things went oddly quiet — legal battles, contributor walkouts, and a compressed relea

If you've ever built ETL pipelines pulling data from MongoDB into Delta Lake using Spark, you've probably hit this wall. The pipeline works fine — until it doesn't. A single document with an unexpected shape is enough to break the entire write, leave the table in an inconsistent state, and send your on-call engineer digging through Spark logs at 11pm. I built and maintained more than 10 of these j
I've been building AQE (Atomic Quantum Engine), a DOM selector engine that replaces tree traversal with flat bitmask operations. Instead of walking the DOM on every query, each node gets a 64-bit BigInt mask at sync time. Matching becomes a single integer AND. AQE Light is the free, open-source version — zero dependencies, MIT license, on npm now: npm install atomic-quantum-engine I'm looking for
