It is by no means the gravest linguistic crime of the React epoch,1 but "state management" grates like nails on chalkboard.

It's perilous to disagree with someone as wise and thoughtful as Jeremy, but for the past fortnight his post in response to Apple's iOS 27 marketing invades my quiet moments like a cricket in the attic.

TL;DR: Armed with new powers to rein in the worst excesses of mobile's duopolists, antitrust bodies around the world are struggling to find their footing, and an incurious tech press is letting it pass with nary a nod. Browsers are app stores too, but that perspective is almost entirely absent from ...

Twitter's descent into a gutter of the lowest order has been wrenching: Elon Musk’s Grok and the Mass Undressing Scandal As I draft this, a week later, it appears pressure from civil society, investigations by regulators, and outright bans on multiple continents have forced Musk to back down to an u...

Eric Prouzet And now we see it clear, like a Cupertino sunrise bathing Mt. Bielawski in amber: Apple will censor its App Store at the behest of the Trump administration without putting up a fight.

Photo by Photo by Artan Sadiku Commentary about browsers and the features they support is sometimes pejorative towards pre-standardisation features. Given Apple's constriction of Mozilla's revenue stream and its own strategic under-funding of WebKit, this usually takes the form "Chromium just ships ...

TL;DR: Market competition underlies the enterprise of standards. It creates the only functional test of designs and lets standards-based ecosystems route around single-vendor damage. Without competition, standards bodies have no purpose, and neither they, nor the ecosystems they support, can retain ...

Anyone who has worked closely with me, or followed on social media [, ], will have seen a post or comment to the effect of: Names and dates on docs. Every time. Don't forget.
