LCP image subparts are finally here!! 🤩

Reminder that this changed rolled out in Chrome 133. If you’re seeing worse LCP times and load your LCP images from another domain (and didn’t have the TAO header set) then that could be why. Read the full thread for details.

Tips for sleeping on a plane yahoo answers. I'm on an 8:45 flight, tired (because I forced myself to sleep very little the night before, hoping to fall asleep on the plane), but I can't sleep... Any tips? Wrong answers only.

The video from my closing keynote to #perfnow is out! I talked about how to approach web performance problems--kind of a beginner's guide to becoming an expert. I hope you enjoy!

The choice of ALT text is not primarily an SEO decision. If you like working with structured processes, check out, bookmark, share, and use this decision tree of when & what to use as ALT text, when it comes to accessibility.

Anytime I am helping someone with CSS and they seem to have the wrong mindset in how they approach writing it, I tell them to watch this video by @miriam.codes As far as I'm concerned it should be required viewing for anyone who is learning CSS. youtu.be/aHUtMbJw8iA?...

Does anyone know a meetup that pays speaker honorariums? I might get enough sponsors to offer a modest one for the web perf meetup I'm co-organizing with @guaca.bsky.social Was thinking $50/speaker (20-25 min talks) & $20 for the organizer. What would potential sponsors & speakers think of this?

I've had a few people reach out to me recently asking for help with LCP issues where they are looking at optimising the wrong thing. They were asking what frontend improvements they could make when that was not the problem. Yup it's time for another long thread to try to explain... 🧵 1/17

My @perfnow.bsky.social talk is out from behind the paywall: youtu.be/0XwWVjQOmyg?... It's an attempt to discuss *why* it's important that we get frontend culture refocused on users, rather than "DX" snake oil.

The Wappalyzer extension (2M users) loops over more than 6,000 web technology detections I reached out to them about using this yielding technique and today they actually released v6.10.77 with the fix! A 700ms long task is now many 50ms tasks 🎉
