Hey @grebenyuk.bsky.social - I'm looking for the Image-Frameworks-Benchmark repo you linked in your Nuke landing page to see an up-to-date comparison between SDWebImage and Nuke. Is that repo gone?

Nitro almost has 1k stars... 🤩

another day, another react-native core PR merged

Another PR by me to Bluesky merged 🥰

Samuel@samuel.fm · last yr.

just merged this PR from @mrousavy.com to improve android startup times - in my testing, I saw ~4% speedup, but Marc has seen upwards of 12% in other apps. awesome stuff! github.com/bluesky-soci...

react-native-mmkv is still the fastest storage solution for React Native! 🔥

Pavlos Vinieratos (pvinis)@pav.vin · 2y ago

Seems like MMKV is still king! But also, props to AsyncStorage went from 240ms down to 50ms since React Native 0.68!

Which storage solution is best for your @expo.dev project? I took @mrousavy.com benchmark repo, moved it to expo, and added expo-sqlite too. Results 👇

use MMKV! 😉🚀

Oussama Bouthouri@bouthouri.bsky.social · 2y ago

The cool #buildinpublic thing of the day. I benchmarked energyxp.app startup time on different devices and switched from async storage to mmkv. 60% faster on my iPhone! @mrousavy.com Kudos, that's some amazing work!

road to 1k stars 🙈

i hope no one reads my commit messages

Objective-C crash course

still can't believe how smooth VisionCamera + Skia is - this face blur Skia filter runs in a JS Frame Processor at 120 FPS! 🤯

@sebjvidal.bsky.social good to see you here!

Introducing Unistyles 3.0! ✨ After months of development, I’m excited to present the brand-new version of Unistyles. We’ve shipped a ton of new features that will redefine how you build your React Native applications. 🧵

had a chance to drive this beautiful Murcielago recently - that thing is truly a piece of fine italian art

i should touch some grass

if VisionCamera runs on this 11 year old tablet, it can run anywhere! 💪

how's your friday?

creating a custom "callable" implementation in C++ - man, capturing stack-allocated arguments in a possible heap context is hard...

And finally @mrousavy.com doing some Marc Rousavy / Nitro stuff 🧨 (10/10🧵)
