6 years ago I started a side project to build a web accessibility tool that prioritises simple reporting and quick feedback loops so that teams can fix a11y regressions before they affect users.

I am so proud to say that side project is now finished, and A11y Pulse is live.

Always, always happy to see @yoav.ws get a shout-out. So much incredible work has happened because of him. Most recent example—speculation rules in WebKit. #perfnow

Google's performance thresholds are not your thresholds. Remember that Core Web Vitals are certainly a good starting point, but not the end goal. Don't aim for somebody else's target, correlate with your own real user conversions and set your own goals.

So they didn’t like the ad. Let’s just post Reagan’s 5 min speech against tariffs as it appears on YouTube.

Over and over. On all platforms (some of y’all are still on X).

We've already had a great response to this. Thank you everyone who took the time to make a ranking - I know there's a lot of proposals.

If you haven't, there's still time!

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.

So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.

I've been exploring @speedcurve.com's new Vitals Overview dashboard with some customers for a week or so now, and all I can say is WOW.

Not only is it fun to play with, it also halves the time it takes to investigate #webperf and #ux issues.

The trans partner of Tyler Robinson had no knowledge about it and was told to delete messages but didn't and instead turned them immediately over to the police and cooperated.

Yet, the right is demonizing her and blame everything on trans people despite the trans person here doing the right thing.
