Build faster with Buck2: Our open source build system
Buck2, our new open source, large-scale build system, is now available on GitHub. Buck2 is an extensible and performant build system written in Rust and designed to make your build experience faster and more efficient. In our internal tests at Meta, we observed that Buck2 completed builds 2x as fast as Buck1. Buck2, Meta’s open source large-scale build system, is now publicly available via the Buc
Open-sourcing Sonar, a new extensible debugging tool – Facebook Code
One challenge that comes from having many engineers working collaboratively on larger apps is that typically no single person knows how every module works. This segmentation of knowledge and expertise can make it difficult to develop new features, investigate bugs, or optimize performance. To help engineers at Facebook manage this complexity, we built Sonar, an extensible cross-platform debugging
Facebook video adds AV1 support
The recent release of AV1, a new open, royalty-free video format, promises to be an important step forward in compression efficiency. Following our publication of detailed real-world AV1 benchmarking tests, Facebook is now adding trial support for the AV1 format to Facebook video. This allows engineers and the general public to view sample AV1 content today. Browser support for the official AV1 re
Open-sourcing Litho, a declarative UI framework for Android
Open-sourcing Litho, a declarative UI framework for Android One challenge in Android development is achieving smooth UI performance. Developers can spend a lot of time optimizing, squeezing out every bit of speed from their UI code, and yet still experience lag and dropped frames in complex scenarios. At Facebook, this problem is relevant to us because more than 1 billion people use our app on And

Keyframes: Delivering scalable, high-quality animations to mobile clients
Keyframes: Delivering scalable, high-quality animations to mobile clients Reactions are a way for people to more easily express themselves on Facebook. As we began building the feature, we wanted to provide a high-quality experience that felt fun at every step, including how the Reactions were displayed, how they moved on the screen when people interacted with them, and how they were dismissed.

Facebookを支える最高レベルにエコでクリーンな巨大サーバー施設をザッカーバーグCEOが公開
2013年にFacebookがスウェーデンに建設したデータセンターは、Facebookいわく「世界でもっとも効率的なデータセンター」だとのこと。そのFacebook自慢のデータセンターの内部を、マーク・ザッカーバーグCEOがFacebookページで公開しています。 (9) Mark Zuckerberg - Over the next few months, I'm going to start... https://www.facebook.com/zuck/posts/10103136694875121 巨大なサーバーが整然と並べられた巨大な部屋。これはFacebookのテクノロジーを支えるデータサーバー内の様子です。 サーバーの裏面はこんな感じ。ケーブル類は適宜まとめられていて、乱雑さは見られません。機器の数を減らすことは効率を高めるのにも、故障時のメンテナンス性を高めるのにも効果的

Introducing the Events From Facebook App | Meta
Update on May 3, 2023 at 12:00PM PT: We transitioned the Facebook Events app to the Facebook Local app in 2017 and that app was deprecated in early 2021. People are still able to create and find events on Facebook by visiting facebook.com/events. Originally published on October 7, 2016 at 10:00AM PT: Every day, more than 100 million people use Facebook events to discover things they can do with th
Segmenting and refining images with SharpMask
Can a computer distinguish between the many objects in a photograph as effortlessly as the human eye? When humans look at an image, they can identify objects down to the last pixel. At Facebook AI Research (FAIR) we're pushing machine vision to the next stage — our goal is to similarly understand images and objects at the pixel level. Over the past few years, progress in deep convolutional neural
The mobile device lab at the Prineville data center
As more people around the world come online for the first time, we want to make sure our apps and services work well for everyone. This means we need to understand the performance implications of a code change on both high-end and typical devices, as well as on a variety of operating systems. We have thousands of changes each week, and given the code intricacies of the Facebook app, we could inadv
