Facebook for iOS (FBiOS) is the oldest mobile codebase at Meta. Since the app was rewritten in 2012 , it has been worked on by thousands of engineers and shipped to billions of users, and it can support hundreds of engineers iterating on it at a time. After years of iteration , the Facebook codebase does not resemble a typical iOS codebase: It’s full of C++, Objective-C(++), and Swift.

Last summer we teamed up with the New York Times to analyze the re-routing of internet service to Kherson, a region in southern Ukraine that was, at the time, under Russian occupation. In my accompanying blog post , I described how that development mirrored what took place following Russia’s annexation of Crimea in 2014. Along with the Russian-held parts of eastern Ukraine, these regions have experienced a type of Russification , an assimilation where the Ukrainian residents of these regions hav

As DoorDash made the move from made-to-order restaurant delivery into the Convenience and Grocery (CnG) business, we had to find a way to manage an online inventory per merchant per store that went from tens of items to tens of thousands of items. Having multiple CnG merchants on the platform means constantly refreshing their offerings, a huge inventory management problem that would need to be operated at scale.

A lot has changed since the initial launch of our basemap in late 2020. We’re Meta now, but our mission remains the same: Giving people the power to build community and bring the world closer together. Across Meta, our family of applications (Facebook, Instagram, WhatsApp, among others) are using our basemap to connect people through functions like status updates, location sharing, and location-based searching.

It would be almost impossible to build a scalable backend without a scalable datastore. DoorDash’s expansion from food delivery into new verticals like convenience and grocery introduced a number of new business challenges that would need to be supported by our technical stack. This business expansion not only increased the number of integrated merchants dramatically but also exponentially increased the number of menu items, as stores have much larger and more complicated inventories than typica

It offers higher quality at a much lower bit rate compared with previous generations of video codecs. Meta has worked closely with the open source community to optimize AV1 software encoder and decoder implementations for real-world, global-scale deployment.

We kicked off this year by introducing our vision for transparent pricing that would make it as frictionless as possible for companies of all sizes to get started with product analytics. The problem we’ve seen across B2B software at large is that vendors hide their pricing, forcing expensive discovery calls and negotiations that waste time and leave customers questioning whether they’re getting a good deal (and they’re often not).

Traffic telemetry is the data collected from network devices and used for analysis. With traffic telemetry, engineers can gain real-time visibility into traffic patterns, correlate events, and make predictions of future traffic patterns. As a critical input to a network observability platform, this data can help monitor and optimize network performance, troubleshoot issues, and detect security threats.

In recent years, the rapid development of cloud-based networking, network abstractions such as SD-WAN, and controller-based campus networking has meant that basic, day-to-day network operations have become easier for non-network engineers. The result we’re starting to see today is a sort of consolidation of networking tasks, leading to a need for only a small number of highly skilled network engineers to handle the less frequent heavy lifting of advanced design and troubleshooting.

A cornerstone of network observability is the ability to ask any question of your network. That means having an unbound capacity to explore the tremendous amount and variety of network telemetry you collect. It means seeing trends and patterns from a macro level, but it also means getting very granular to pursue any line of analysis of your data. Collecting information from flow records, SNMP, streaming telemetry, BGP, eBPF, and so on is indeed very important.
