We created a usage-based billing system with ultrahigh throughput; reliable, real-time events processing; and support for complex pricing models. Doing so required reimagining how to build a highly scaled, highly reliable event streaming platform.
Here we explain how we made our data pipeline scale to 700 million events per second while becoming more resilient than ever before. We share some math behind our approach and some of the designs of our systems, as well as issues that we had to face and bugs we had to chase.

Refactoring is something developers do all the time—making code easier to understand, maintain, and extend. While IDEs can handle simple refactorings with just a few keystrokes, things get tricky when you need to apply changes across large or distributed codebases, especially those you don’t fully control. That’s where codemods come in. By using Abstract Syntax Trees (AST), codemods allow you to a

A once-revered perk of some tech workplaces, the status of ‘side project time’ seems to have slipped in recent years. Frederick O’Brien believes it deserves a comeback.
Do types actually make developers more productive? Or is it just more typing on the keyboard? To answer that question we’re revisiting Diff Authoring Time (DAT) – how Meta measures how long it takes to submit changes to a codebase. DAT is just one of the ways we measure developer productivity and this latest episode […]
Shouldn’t there be a way to keep your apps or project data private and improve performance by reducing server latency? This is what on-device AI is designed to solve. It handles AI processing locally, right on your device, without connecting to the internet and sending data to the cloud. In this article, Joas Pambou explains what on-device AI is, why it’s important, the tools to build this type of
In December, we experienced two incidents that resulted in degraded performance across GitHub services.

In the last few months, we secured 75+ GitHub Actions workflows in open source projects, disclosing 90+ different vulnerabilities. Out of this research we produced new support for workflows in CodeQL, empowering you to secure yours.
We know that browsers do all sorts of different things under the hood. One of those things is the way they not only *fetch* resources like images and scripts from the server but how they [prioritize those resources](https://www.debugbear.com/blog/request-priorities?utm_campaign=sm-7). Chrome and Safari have implemented a “Tight Mode” that constrains which resources are loaded and in what order, bu
