Saw the Bluesky team is already very busy working on amazing features (it seems that commits and PRs are even made and opened on weekends). Should do my best not to increase their workload.

Incredible execution by @zeta.vg! A thorough explanation (including an explanatory video) and a very focused scope making it a breeze for the Bluesky developers to accept a meaningful contribution from what I assume is an unknown user.

Another big perf win for Android users! Thank you @zeta.vg!

Thank you! It’s also impressive how swiftly they review, test, merge, and release contributions. I would recommend the Bluesky app to OSS enthusiasts as a widely-used RN app to contribute to.

Thanks for testing it out! Glad to make the Bluesky mobile app more appealing for Android users.

Glad you mentioned it! My ultimate goal is to bring the bird back 😈
(Decided 2 seconds ago)

Since Twitter isn’t open-sourced, I finally ended up here 🐦

A poster taped on a wall. The main text on the poster reads “BIRDS AREN’T REAL” in bold letters. Below this, it says “Wake up, 35c3!” and features a silhouette of a bird with the text “GOVERNMENT SURVEILLANCE DRONE” underneath it.

So this may be a react-native-reanimated worklet function (when used as an onScroll event handler?) thing.

Well, I do expect this to have some perf difference (or not, due to some JS runtime optimization magic?)

But, yes, it shouldn't be that significant.

At least, it shouldn't cause a function running at 60fps to lag.

const obj = {
a: 1,
b: 2,
c: 3,
d: 4,
};

function fn() {
return obj.a;
}

const obj = {
a: 1,
b: 2,
c: 3,
d: 4,
};

const { a } = obj;

function fn() {
return a;
}

Did a quick search & couldn’t find any documentation or discussions on this... tip?

If anyone knows of someone talking about this somewhere, please let me know!

Took me some time to identify the cause of this issue.

It’s interesting how accessing a property of a tiny object (just 4 properties!) in a react-native-reanimated worklet function can noticeably impact performance.

Merged PR into main at bluesky-social/social-app: Fix laggy scrolling on mobile app's home screen, etc. (#4108)

The downside of having a highly customized theme is that it has to be maintained from time to time. Luckily, even without maintenance, this hasn't broken down within half a year.

Switching to VSCode for the third time, and one of the main reasons is probably for Copilot Chat. It seems promising this time; the features I frequently used in Sublime Text appear to be usable in VSCode now.

First thing to do is to replicate the theme I used in Sublime Text over to VSCode.

發現了如何改善 Bluesky app 在 Android 上，時間軸的捲動會卡頓的問題。 youtu.be/ipZeTkb2mAk

可能算是 react-native-reanimated worklet function 的一個小地雷？

（App 時間軸的捲動流暢度跟 web app 版比、或是時間軸頁面的捲動和個人檔案頁面的捲動相比，滑順程度有明顯落差。）
（比較好的 Android 裝置可能感受不太出來，但中階或以下會隨著等級越低越到無法接受的程度。）

稍微看了一下，撇除 X API 的定價可能是無法忽略的開支，要獲得穩定的 API 供應也是堪憂呀⋯⋯畢竟他們有無預警封殺 3rd party client 的紀錄，而且這樣也擋了廣告的獲利。

雖然似乎還是有一些 3rd party app 活著，初步研究了一下他們是怎麼做到的 🤔
