Handling CSS :hover off the main thread! This is a work in progress but I love this so much, I just have to share it! 🤓 Ladybird on the left, Chrome on the right. The demo runs JS for 250ms repeatedly, to simulate a busy page.

Work in progress, but this is so fucking cool I just have to share.. I'm moving the entire CSS pipeline off the main thread in Ladybird. This allows us to animate any CSS properties we want and they just keep going smoothly despite heavy JS execution! Video demo is animating a bunch of flex and grid layouts while JS churns on the main thread. Same demo in Chrome for comparison. Welcome to the future, bros 😎

I moved CSS transform and opacity animations off the main thread in Ladybird and I just love it so much 🤩 Now we can chew on all that JS framework bloat while elements fade in and fly around smoothly!

May the 4th be with you! This one is still very much work in progress, but for Star Wars day, it felt appropriate to share what I have so far. Having a ton of fun working on this; I love animating so much, it's unreal.

I really want to work on this again but I don't have the time for it anymore. So I'm going to launch a Kickstarter during June Steam Next Fest where you can also try the demo.

TAEHYUNG ABOUT YEONTAN “The reason I decided to post this message today is because, recently, Yeontan (my dog) embarked on a long journey to the stars. I thought a lot about how to share this news with you, but I felt that it was right to let ARMYs, who have sent so much love to Yeontan, know, so I’m sharing this news now. I believe Yeontan would feel happy if ARMYs also remember him fondly as he sets off on this journey.”

Finally this can see the light!! I waited so much to share my work for #HelluvaBoss S0108! Loved working on this episode I enjoyed every second animating the yellow dog!! She was tough but it's a delight to see a finished shot of her! I love Beelzebub 🥹💛

FSD 12.5 runs a red light I want to share this to have a healthy discussion regarding this situation. This isn't in anyway an attempt to hate on FSD 12.5, I still believe this is the best release of FSD so far. Yesterday on my drive FSD for the first time ever (for me) decided to proceed on a VERY stale (red?) light. I was a bit surprised about its decision to do this, and I am wondering if perhaps the traffic light being set back (before the intersection starts there's a light on my left) has anything to do with this? Technically the car passes the light/stop line as it is still yellow. As a human driver I may have proceeded on this light if I was in a rush, but I am not sure if a robotaxi should make that same decision. Tesla AI ΛI DRIVR Dirty Tesla Sawyer Merritt Elon Musk Nick Arek Sredzki Srihari Sampathkumar Any opinons on this folks?

SUCCESS!! I managed to patch the boot image on my bootloader unlocked Quest 1 and got 90 Hz on the Quest 1, I am probably the first person outside of Oculus/Meta to have this. Surprisingly, it runs pretty good on games like Beat Saber, I just used a WebXR demo for the FPS.

Hard work never goes to waste. I came a long way. I always believed in myself but I never thought at this age I would headline in the indigo o2. Hard work and dedication. I trained so hard for this fight and it paid off. On the next one 🇸🇴

I was about to work (Codex was about to work) on thread/resume optimisation, but I got sidetracked by adding a zoom transition on the plan card. It sounded much more important.

Always been nervous to enter this place but decided to during the day. Best prices I have seen pretty much on the strip. Def recommend it for anyone tryna save a few bucks. It is right across from the horseshoe (flamingo road).
