Ask HN: Should browsers natively support React-like UI patterns?

Posted by xfr on Friday November 07, 2025 @01:20AM
from the ask-hn dept.

Every major web framework today (React, Vue, Solid, etc.) ends up re-implementing the same ideas in JavaScript: component trees, diffing, and DOM reconciliation. This means every frame of UI work runs through an interpreted, garbage-collected layer that the browser ultimately has to translate back into the real DOM anyway.I’ve been thinking about what would happen if browsers added native,...

First, I am extremely impressed by the demo. It looks truly groundbreaking.

Could you elaborate on the types of tasks and data sources used to train Ace, and how these contribute to its performance on desktop automation?

Ace is said to outperform other models on your suite of computer use tasks. Can you provide more details on these benchmarks and how Ace compares to existing automation tools?

Re:Five Walled Gardens: Operating systems are holding browsers back [pdf] on Monday September 26, 2022 @09:23PM (#32990684)
The main problem with alternative browsers on iOS is JIT compilation. It breaks codesigning and thus is only allowed by Apple’s own code. If random third party apps could JIT their code, it would defeat many security measures
Re:How Secure Boot Works on M1 Series Macs on Wednesday December 29, 2021 @11:09AM (#29726090)
There are several inaccuracies.

Everything after “Darwin Kernel Version 21.2.0” is XNU, not iBoot. This is when macOS starts according to the diagram. You don’t see logs from iBoot.

I have no idea what this means:

> The end of the kernel-only phase, which is entirely iBoot, comes almost 20 seconds after the start.

It’s already been confirmed that kernel extensions will work on the ARM macs. From there it seems straightforward to get a basic Linux loader going.

Yes it is a strange metaphor but language like “I might stumble a bit and touch her in ways she doesn't like” is rapey and comparing women to config files is just weird. The whole comment feels like it is objectifying women
Re:Ask HN: Feasible Alternative to the MacBook Pro? on Sunday October 20, 2019 @08:59AM (#21303830)
This is straight up misogynistic and is a great example of why women are driven away from our industry, because of language like this.

Ctrl-R and Ctrl-S please. Using the arrow keys for searching through history quickly (i.e. without leaving the home row) sucks.

The "Randomize order of array" snippet isn't actually random. It would just confuse the sorting algorithm.

I used to use the Hangouts Chrome app but I will be using this now instead.

Sweet, now I don't have to keep Chrome around for Hangouts on OS X.
