Which feature in Safari 26.2 is your favorite??
I always try to imagine the answer while writing… will they be more excited about command/commandfor or field-sizing? Are the HTML improvements the headline? Or CSS/SVG/JS…?
Then I’m curious, what do you really think?

I sent my first Internet email 30 years ago 🙀
Fun detail: my email address wasn't even a real personal inbox. It was more like an omnibus address that looked like:
firt%[email protected]
So yes, I was already using firt as my username back then. 😅

Meta's big reveal today: smart glasses with a display and a wristband for gesture control.
Cool. I'm now wearing my Google Glass (2013) + Myo armband (2014).
Same thing! minus the AI 😂

I’ve tested a couple of agentic browsers recently.
They were too slow and failed at very basic tasks, like saving a calendar appointment, running a simple search, or filling out a web form from a JSON record.
Right now, they’re still just a promise of a possible future.

The word "bully" is the key in Cook's statement to understand that he is talking about my letter, even if it's subconscious. The statement happened a few days after my letter went viral (I also sent Tim Cook a copy), and he never used that term before or after that day.

Moral of the story: a well-founded, outspoken critical stance can make a difference.

Five years ago, I published an open letter denouncing Apple employees for their hostile and bullying attitude toward developers who voiced criticism.
It gained enough traction that, a few days later, Tim Cook briefly responded to it in the U.S. Congress.

I built the full curriculum: J2ME, .NET, WAP, SMS, Symbian, Palm & more — years before iPhone or Android even existed. 😀
