Element-Scoped View Transitions are gonna be **SO GOOD** There’s still some details to settle, but the main thing is there: run VTs on a subtree of the DOM, allowing parallel VTs. And with `view-transition-scope` you can limit the scope of `view-transition-name` values, allowing VTs to be nested.

If you kinda understand Anchor Positioning, but it still surprises you from time to time, then most likely this is the missing piece of information: the Inset-Modified Containing Block (or IMCB for short). The anchored box gets positioned within that IMCB.

Look what they did to Notepad. Shut the fuck up. This is Notepad. You are not welcome here. Oh yeah "Let me use Copilot for Notepad". "I'm going to sign into my account for Notepad". What the fuck are you talking about. It's Notepad.

Windows Notepad, the native simple text editor, now has formatting options and a Copilot button.

React is load-bearing in most orgs in the sense that it's what binds terrible choices together tightly enough to keep them from being individually evaluated.

Adam is the brightest, most authentic, inspiring, truly creative, high performing, deeply passionate, and nice person I have ever worked with. And then my employer decided to terminate his role. I am gutted and sick to my stomach. I will miss you, my friend 💔
