The Blog

Cheatsheets, tutorials, and the occasional rant about why your WordPress site is slow

What You’ll Find Here

This isn’t your typical dev blog filled with “10 Amazing JavaScript Tricks” clickbait. It’s a collection of resources I’ve built while solving actual problems—the kind you run into at 2am when a client’s site is down or you’re debugging why a plugin is eating 500MB of memory.

Most of these started as notes to myself. Turns out other people find them useful too.

Popular Cheatsheets

These get linked around the web fairly regularly. They’re dense, practical, and assume you know what you’re doing but just need a quick reference.

  • WordPress Performance Optimization Cheatsheet — Everything from database query optimization to object caching, CDN configuration, and the plugins that actually matter. Built from dozens of sites I’ve pushed from 4-second loads down to sub-1-second.
  • PHP WordPress Security Hardening Guide — The essential checklist for locking down WordPress installations. File permissions, database prefixes, security headers, and the .htaccess rules that actually prevent attacks instead of just slowing down your site.
  • MySQL Query Optimization for WordPress — How to identify slow queries, optimize your database structure, and fix the N+1 problems that kill performance. Includes the actual queries I run to diagnose issues.
  • Technical SEO Implementation Checklist — Schema markup, canonical URLs, pagination handling, hreflang tags, and all the technical SEO work that actually moves rankings. No theory, just implementation.
  • WordPress Plugin Development Boilerplate — Starter code for building custom WordPress plugins the right way. Includes proper activation/deactivation hooks, database table creation, admin interfaces, and security best practices.
  • .htaccess Rules That Don’t Break Things — Redirects, security headers, browser caching, and compression rules that I’ve tested across hundreds of hosting environments. Copy-paste ready.
  • WordPress REST API Quick Reference — Endpoints, authentication methods, custom post type integration, and the gotchas that waste hours if you don’t know them.
  • CSS Grid & Flexbox Cheatsheet — Because I still need to look this stuff up. Properties, values, browser quirks, and the patterns I actually use in production.

Occasional Observations

Not everything is a tutorial. Sometimes it’s just thoughts on why the industry does things the hard way, why most WordPress “optimization” plugins are snake oil, or why I still use MySQL instead of jumping on every new database trend.

These posts tend to generate either nodding agreement or angry emails. Both are fine.

How to Use This Blog

Everything here is free to use. The cheatsheets are meant to be printed, bookmarked, or copied into your own notes. The code is yours to use in commercial projects. No attribution required, though always appreciated.

If you find an error or have a better way to do something, let me know. I update these regularly based on what’s actually working in production environments.
