My Saturday project: make HEY load faster in Ladybird 👋🚀 Got it down from ~1 s to ~400 ms with two changes: - Our HTTP cache now supports heuristic freshness lifetime (per RFCs 9110 & 9111) - We delay rendering until we have all CSS imports (no more FOUC!)

After some Saturday night debugging, I finally got Google Sheets running in Ladybird 🤓🧮 It's glitchy and unstable, but this is solid progress! Been told many times over the years that "you'll never get complex stuff like Google Docs running" lmao 😄

Diablo running at full framerate (20 fps) in Ladybird 😈 (This was running at 11 fps yesterday, but after some optimization work and a setInterval() fix, we're gaming like it's 1997! 👴)

We switched all our network requests in Ladybird to be unbuffered, which means we can now see ChatGPT responses incrementally as they come in! Props to Alexander Kalenik for fixing this (and all the bugs it uncovered)!

Speaking of love letters to the web, here's Ladybird trying its best to render this year's Shopify BFCM page 🤓💚 I had to hack our animation system to get it running, the little virtual PC doesn't work, and our Wasm performance is downright sad, but hey... pinball! 👨‍🚀

First instance of a YouTube video playing in Ladybird! 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!

Watching movie trailers on IMDb with Ladybird 🐞🎞️ (Had to fix some SVG and CSS bugs for this to look as nice as it does. Have to fix a lot more things for performance to be good enough.. 😅)

Did you ever wonder who invented browser tabs? 🤔🌐 Turns out it was a little browser called InternetWorks by BookLink Technologies! BookLink was later acquired by AOL. I tracked down version 70(!) of InternetWorks and got it running on Windows 95. The default home page is delightfully "90s web design", and it came with a bunch of recommended web sites to visit. This was before CSS, but the browser actually allowed you to change the style of each individual HTML tag. I tested this feature in the video and even ran into a bug (changing H1 to a font with different metrics keeps using the old metrics until you reload the page!) 😅

Working on putting Ladybird networking on top of curl (cc daniel:// stenberg://) 🐞🥌 Massive speed-up compared to our old HTTPS stack (that we built from scratch for SerenityOS). Uncached load of my For You page goes from 38 sec to 8 sec! 🤓🚀

Playing Om Nom (HTML version) in Ladybird 🐞🔪🪢 I remember being very impressed when this came out back in 2012(?). It felt like the web was finally gonna fill the shoes of Adobe Flash! Getting it to run in our new browser 13 years later, I'm once again impressed, but this time by our team for making it not only run, but run well! 🤓🌠

First look at Firefox DevTools protocol support in Ladybird 🤓🐞🦊 This will allow us to use the excellent developer tools in Firefox to inspect/debug web content in Ladybird (until we have our own developer tools)

We're working on WebGL support in Ladybird and it's progressing nicely.. In fact, Lubrsi just got Shadertoy working! 🤩🤯

First look at Figma running inside Ladybird! 🎨🤓 Bottom left window is Ladybird, top right is Chrome. There are numerous correctness and stability issues but we'll work our way through them! Video from Lubrsi who fixed a million WebGL issues to make this happen 🫡🚀

While I have Solaris 7 up & running, let's also take a look at Amaya, an old web browser/editor from the W3C itself. 🤓🌐✍️ Amaya existed for many years but was sadly discontinued in 2012. More history here: Here's a clip of me using Amaya 4.0 for Solaris, released in Nov 2000. At the end, I press Ctrl+X, Ctrl+S, which is the save shortcut. That's what causes the right (HTML source) window to synchronize.
