Meta Open Source is officially transferring Jest, its open source JavaScript testing framework, to the OpenJS Foundation. With over 17 million weekly downloads and over 38,000 GitHub stars, Jest is the most used testing framework in the JavaScript ecosystem and is used by companies of all sizes, including Amazon, Google, Microsoft, and Stripe. We...

More than 3 billion people around the world rely on our services each month. On mobile, around 57 percent of people on Facebook for Android and 49 percent of those on Facebook for iOS use the app in a language other than English. Delivering the best experience for these people, in their own language, is an important step in helping people around the...

Building infrastructure that can easily recover from outages, particularly outages involving adjacent infrastructure, too often becomes a murky exploration of nuanced fate-sharing between systems. Untangling dependencies and uncovering side effects of unavailability has historically been time-consuming work. A lack of great tooling built for this,...

Over the years, Meta has invested in a number of storage service offerings that cater to different use cases and workload characteristics. Along the way, we’ve aimed to reduce and converge the systems in the storage space. At the same time, having a dedicated solution for critical package workload makes everyone happier. Having this in place is necessary...

Since Instagram runs one of the world’s largest deployments of the Django web framework, we have natural interest in finding ways to optimize Python so we can speed up our production application. As part of this effort, we’ve recently open-sourced Cinder, our Python runtime that is a fork of CPython. Cinder includes optimizations like immortal objects,...

Delivering on our vision for the metaverse will require us to reimagine a network infrastructure capable of supporting the computing platforms of the future. Although the metaverse is still a ways off, elements of it are already underway and we are already collaborating with telecommunications companies around the world to develop shared, open access...

At Meta, our internal data tools are the main channel from our data scientists to our production engineers. As such, it’s important for us to empower our scientists and engineers not only to use data to make decisions, but also to do so in a secure and compliant way. We’ve developed SQL Notebooks, a new tool that combines the power of SQL IDEs and...

Data minimization — collecting the minimum amount of data required to support our services — is one of our core principles at Meta as we continue developing new privacy-enhancing technologies (PETs). We are constantly seeking ways to improve privacy and protect user data on our family of products. Previously, we’ve approached data minimization by exploring...

Silent data corruptions (SDCs), data errors that go undetected by the larger system, are a widespread problem for large-scale infrastructure systems. Left undetected, these types of corruptions can cause data loss and propagate across the stack and manifest as application-level problems. Silent data corruptions (SDC) in hardware impact computational...

What the research is: Recent research has demonstrated that binary optimization is important for achieving peak performance for various applications. For instance, the state-of-the-art BOLT binary optimizer developed at Meta, which is part of the LLVM Compiler Project, significantly improves the performance of highly optimized binaries produced using...
