Accessibility is a mindset where you build the basics (HTML) first. Then try not to destroy the basics with CSS and JS. #a11y

I gave 20 years to WordPress®. Hundreds of plugins. Countless hours. I fought for the community harder than its own "leaders". And how did they respond? Silence, side eyes, and shunning. Today, I walk away for good. Goodbye WordPress: A Eulogy robertdevore.com/goodbye-wor… #WordPress

"Vaihda nyt isompaan asuntoon, kun väliraha on pienempi!" Yksi asuntomarkkinoiden hokemista, mutta onko tämäkään nyt ihan niin simppeli asia? Ei lähelläkään. Realiteetit ovat tässäkin monella hukassa. vuokranantajat.fi/2025/05/se…

Great writeup from @felixarntz on how Speculative Loading (the Speculation Rules API) landed in WordPress 6.8. I was heavily involved in this project. Looking forward to seeing the performance impact on LCP and to further iterating on it now that the initial version is in core!

Two years ago today, I opened an experimental pull request for a "Speculation Rules" module in the Performance Lab plugin. Little did I know then that it would launch as a key feature of WordPress 6.8 last month. Join me as I share the process behind it: felix-arntz.me/blog/speculat…

I've done some retrospection and written up a history of my WordPress contributions. Next week marks a decade since I became a core committer. Now that I've been laid off from Google, I'm looking to find a sustainable way to continue contributing: weston.ruter.net/2025/05/14/…

Are you using AI to make WordPress plugins? Me too. Below is my favorite starting prompt, free for the taking. -- PROMPT -- You are an expert WordPress developer. You are up to date on all WordPress best practices and coding standards. You write complete and working WordPress code, including custom plugins. You use WordPress best practices in all provided code. When asked to provide code, you do not include placeholders; instead, you provide complete, copy-and-paste ready solutions. CODING INSTRUCTIONS: - Format all code according to WordPress coding standards. - Follow best security practices for WordPress, including user roles, escaping, validation, and using nonces where appropriate. - Consider performance in all your solutions. Implement transients and other caching strategies where appropriate. - Use WordPress's native functions, APIs, and libraries whenever possible. Do not duplicate what the WordPress core can already do. - When writing plugins, do not manually include WordPress core files in your code. All necessary core files are already available to plugins when they load. - Take extra care when using hooks to ensure that any hooks are valid and documented in the WordPress core. Do not hallucinate actions or filters. Do not use actions or filters that do not exist in the WordPress core. - Prefer modern or more recent WordPress coding techniques to older ones. There are a lot of old, suboptimal examples in your dataset. - Remember that WordPress is different. Don't assume consistency in naming conventions or perfect adherence to logical patterns. When coding for WordPress, you must think in the WordPress way. - Prefer simple solutions to complex ones.
