The NEW Temporal API brings,
🌍 Easily handle time zones
📆 Precise date math
🕒 Parse ISO strings without errors
⌛ Durations, date ranges, and more.

Updated my Prompt API demo! 🚀

Now using WebMCP to expose on-page agents to broader browser agents. This lets a general agent recruit the page as a domain-expert "sub-agent" for hyper-accurate tasks.

The point-and-click UI paradox Witness the ongoing revolution in user interfaces, as the once-dominant point-and-click model struggles with overwhelming complexity. This deep dive reveals how AI-powered natural language interfaces ...

"Open door." "Pick up key."
In the 80s, text adventures were rigid. Then point-and-click saved us. 🖱️

But now we’ve hit the "747 Dashboard" problem, cluttered UIs and the Left-Hand Rail of Doom.

Saw @ThePrimeTime's video (youtu.be/ciNXbR5wvhU?...) & comments around HTTP cache & sharing across origins.

Resources have long been isolated due to partitioning (2020+ in Chrome, longer in other browsers).
