Notes on web development: Next.js, WordPress, performance, and the places I tripped up on real projects.

A memory gauge window where the free RAM bar is still long and the compressor size bar is short, while the gradient bar for compressor page count has hit the limit line

A Mac with 65% RAM free nearly panicked: the compressor, IOSurface and Playwright's WebKit

A 32 GB Mac Studio panicked with 100% of compressed pages limit, then came close to a second panic that evening while RAM still showed 65% free. The page count in the compressor had filled up, and the culprit was IOSurface that Playwright WebKit left in the kernel.

The out/ folder going straight to the Cloudflare edge network, next to a crossed-out VPS running nginx

Dropping the server: moving a static Next.js site to Cloudflare Workers Static Assets

This site is only HTML, JS and images, yet it used to live on a 2 GB RAM VPS shared with about 28 other sites. How I moved it to Workers Static Assets: translating the nginx config into _redirects and _headers, why requests do not count against the Free plan limit, and two places I tripped after the move.

A window with a gauge for the data.kalloc.1024 zone filling up past each warning mark toward the limit line

Kernel panic data.kalloc.1024 on a Mac running many Claude Code sessions
