justhtml: A pure-Python 100% spec-conforming HTML(5) parser, with zero dependencies. From @EmilStenstrom. Relatively fast, and returns plain Python objects (a set of nested objects you can iterate over), not lxml/etree trees (so, no new API to learn). https://t.co/F4MwjTjosz

We are proud to share that Cloudflare is sponsoring Ladybird at the Platinum level ($100,000)! It means a lot that a big player like Cloudflare is supporting a small team like ours in building an independent browser for the open web! We're super grateful! 🧡☁️

“Copy Link to Highlight” / scroll-to-text-fragment (creating deep links to arbitrary text/ranges in a web page without hardcoded IDs) is now also experimentally supported in the stable version of Firefox — when you set dom.text_fragments.create_text_fragment.enabled to true

https://t.co/Vl5OYcfoli “So it’s already been decided and we just have to bend over and take the changes our Googlish overlords have decreed!” many people shouted … but that’s not what’s happening here.

Use XSLT3 in frontend JavaScript code in any browser: https://t.co/NIOqD1pqKM. SaxonJS is “high-performance” JS library you can use right now in any web doc/app where you want to do client-side XSLT3 transformations. And stop whining about lack of native XSLT support in browsers.

My ahead-of-time JS engine Porffor eliminates JS cold starts on AWS Lambda. 12x faster and 2x cheaper than managed Node. Still very early but these results should speak for themselves :) Blog with details below.

Chrome is moving away from LevelDB toward SQLite for all backend storage (for IndexedDB too). https://t.co/1ajoWXaUJC says why: LevelDB is no longer being actively maintained (& was always expensive to maintain); SQLite is actively maintained & much better fit in practice anyway

“Can we use Wasmtime to build web script engine?” https://t.co/S0TiwpBWIq from @Yu_Wei_Wu explores the idea of using the (Rust-based) wasmtime https://t.co/EqYEym32BV WebAssembly runtime as the basis for a JavaScript engine (alternative to @SpiderMonkeyJS) for @ServoDev

This one is such a key insight from @awesomekling. If you hire many engineers, you (typically) get many lines of code. The result is a vast code base that is costly to maintain further.

Flow now passes 90% of the web-platform-tests. 👋🇪🇺 👋Apple

First instance of a YouTube video playing in @ladybirdbrowser! And with sound, too! 🤯🐞 This is with MediaSource disabled, so it's using the 360p h.264 MP4 fallback. Props to @Lubrsi who just got this working tonight!

There's lots of data about the usage of web constantly declining, replaced by time on closed platforms (FB, Insta, TikTok) and apps. I think it's true. What are "only the web can do this" experiences you've seen? I want to create as a big a list as possible This comes to

Thanks to @devgianlu and many others, @ladybirdbrowser now passes 99.6% of the WebCryptoAPI WPT tests - the highest score of any browser! This API can be used for encryption and decryption, key generation, signature verification and other useful security features.

On Feb 1st, 12:30 I'll be giving a lightning talk (15 min.) on @ladybirdbrowser at @fosdem in Brussels. After that quick talk I'm happy to have more in-depth discussions, so join me there!

One week into November, @ladybirdbrowser continues pushing forward on web-platform-tests! This is what grinding out a new browser looks like. No glamor, no shortcuts, just inching forward week after week. 🤓📈

Wanna learn how to build a browser from scratch? Check out https://t.co/dnkMvowVQW by @pavpanchekha and @chrishtr 🤓🌐📘 In this (free) book, you build a "basic but complete web browser, from networking to JavaScript, in a couple thousand lines of Python"

I wrote a new blog post for the first time in 6 years:

📝 I set off to find the best way to make video with transparency work on the web. Over 10 bug reports later, it turns out it's better to handle the transparency manually with WebGL. Here's how: https://t.co/HwyTqKsj2i
