We're building a browser when it's supposed to be impossible
Linus Groh of LibJS is an Invited Expert in TC39: https://linus.dev/posts/road-to-working-on-serenityos-and-la...
ECMAScript conformance test results looking good, 87-88% passing at the moment: https://libjs.dev/test262/

Ladybird Web Browser – SerenityOS LibWeb Engine with a Qt GUI
this is a qt frontend (definitely works on linux) for the serenityos browser engine, libweb.
this is a new, from-scratch implementation of both a modern html/css layout engine and a javascript runtime.
see https://libjs.dev/test262/ for ecmascript conformance tests.
the browser engine is far from finished but is able to display moderately complex pages like github.
it's always exciting to see a completely new web engine running in conventional environments like linux!

Show HN: We launched a new web browser
> Our JavaScript engine is decently mature, test262 score tracked here: https://libjs.dev/test262/
In a few years when they have achieved feature parity with Chromium or at least Safari we can discuss this again, but for now it's not ready for real life use.

LibJS JavaScript Engine
See https://github.com/linusg/libjs-test262 for an example, specifically the CMake files and `src/main.cpp`.
The separate website is just to have a nice & short link to the test262 graph and whatever else we'll put there eventually; and also because it's built/deployed in a slightly different way than the main serenityos.org website.

Bun, JavaScript, and TCO
To use this in Bun, you’d have to start Bun with the environment variable “BUN_JSC_useDollarVM=1” and then $vm.createBuiltin(mySourceCodeString)
When using this intrinsic, if any of the arguments are incorrect or it cannot otherwise enable it, the entire process will probably crash. In debug builds of JSC it will have a nicer assertion failure but that is not enabled in release builds
Example code: https://github.com/WebKit/WebKit/blob/17351231b4dedb62d81721...
also happy to answer any questions about Bun

Show HN: Rem: Remember Everything (open source)
Ah, good, let me introduce you to the wonderful world of the Chrome Devtools Protocol! (fka Chrome Remote Debugging Protocol)
I love this API for almost everything browser related. I built my RBI product atop this (BrowserBox: https://dosyago.com), and I think it's a drastically underrated API.
Also, it works out of the box in Edge, Brave, Chromium, and many parts of CRDP are supported by Firefox and Safari^1
