Safari Ripper ☠️

Security researcher Sabri posted a bit of code that will "force restart any iOS device." It's interesting to see HTML & CSS have this kind of dangerous power. It's essentially a ton of <div>s scaled to be pretty huge and then set over a repeating JPG image with each <div> blurring the background via backdrop-filter. It must cause such extreme and unhandled memory usage that it wreaks havoc on the browser as well as the entire operating system.

I was trying to test it out myself and be really careful not to execute it... but of course I did, and it crashed my Chrome 68 on a MacBook Pro. Not the whole operating system, but I had to force quit the browser. Then again, I suppose even while(true) {} can do that!

The comment thread on the gist hast more interesting details, like how it crashes iOS Safari 9+ (including the new version 12!) and weird behavior on the PlayStation 3 native browser.

The Ecological Impact of Browser Diversity

Early in my career when I worked at agencies and later at Microsoft on Edge, I heard the same lament over and over: "Argh, why doesn’t Edge just run on Blink? Then I would have access to ALL THE APIs I want to use and would only have to test in one browser!"

Let me be clear: an Internet that runs only on Chrome’s engine, Blink, and its offspring, is not the paradise we like to imagine it to be.

As a Google Developer Expert who has worked on Microsoft Edge, with Firefox, and with the W3C as an Invited Expert, I have some opinions (and a number of facts) to drop on this topic. Let’s get to it.
