The Performance Inequality Gap, 2026
"The Budget" is an yearly issue where Alex tests out JavaScript sites on median hardware and shares insights for the network landscape. Results show that although median devices get faster every year, mobile JavaScript payloads have doubled since 2015 and less than half of origins pass Core Web Vitals for mobile users.
SPAs are also being used inappropriately at scale and averaging one soft-navigation for every full page load on average. Considering they require more upfront JavaScript, this extra payload doesn't outweigh its benefits for most.

Disagree and Commit
The "disagree and commit" model forces uncomfortable emotional contortions that are hard to practice authentically. Ben argues that by shifting to "disagree and let's see," teams can stay aligned while maintaining emotional honesty about their reservations. This mindset eliminates winners and losers, replacing "I told you so" moments with learning.

Automated Accessibility Testing for React
Learn how to automate accessibility checks in your React apps using tools like axe-core, React Testing Library, ESLint plugins, and end-to-end testing frameworks. This guide covers everything from setting up basic ESLint rules to implementing accessibility tests in your CI/CD pipeline, though manual testing remains essential for catching all issues.

Why Your Best Engineers Are Interviewing Elsewhere
Organizations create hierarchies to manage complexity, but each layer filters out detail and urgency from problems. A $40M ARR SaaS company lost five senior engineers after dismissing warnings about database scalability, costing $1.4 million in replacement fees alone. The real problem wasn't compensation or technical choices, but that information doesn't flow upward through organizational hierarchies until it's too late.

How Good Engineers Write Bad Code at Big Companies
Big tech companies make surprisingly little effort to develop or retain long-term system expertise. "Old hands" who do develop deep knowledge are moved to different services or become so overloaded with reviews that quality suffers. This constant churn means most engineers work as perpetual beginners on decade-old codebases, making mistakes inevitable regardless of individual competence.
