The best problem-solving writing in software engineering — databases, performance, security, frontend and distributed systems, in one feed.
Motion can be tricky: too much distracts, too little feels flat. Ambient animations sit in the middle. They’re subtle, slow-moving details that add atmosphere without stealing the show. In part two of his series, web design pioneer Andy Clarke shows how ambient animations can add personality to any website design.
This post explores the performance of BPF LPM tries, a critical data structure used for IP matching. It delves into the trie algorithm, presents benchmark data, and explains how the current kernel implementation’s design choices lead to performance bottlenecks.
The DESC clause in CREATE INDEX is rarely needed. I'll show use cases for descending indexes, including storage efficiency and performance.
To prepare for Schema 2025, we combed through Shortcut archives to pull together our design systems greatest hits.

At Meta, we are constantly pushing the boundaries of LLM inference systems to power applications such as the Meta AI App. We’re sharing how we developed and implemented advanced parallelism techniques to optimize key performance metrics related to resource efficiency, throughput, and latency. The rapid evolution of large language models (LLMs) has ushered in a […]
A simple but powerful mental model for working with AI: treat it like an enthusiastic intern with no real-world experience. Paul Boag shares lessons learned from real client projects across user research, design, development, and content creation.
Today, there's no way to audit a site’s client-side code as it changes, making it hard to trust sites that use cryptography. We preview a specification we coauthored that adds auditability to the web.
If alone time is your love language—don’t worry, it’s ours too—you can still attend, learn from, and enjoy big events like GitHub Universe. Here are some practical tips on how.
Sapling is a scalable, user-friendly, and open-source source control system that powers Meta’s monorepo. As discussed at the GitMerge 2024 conference session on branching, designing and implementing branching workflows for large monorepos is a challenging problem with multiple tradeoffs between scalability and the developer experience. After the conference, we designed, implemented, and open sourc
We’re sharing details on our journey to scale Meta’s Backbone network to support the increasing demands of new and existing AI workloads. We’ve developed new technologies and designs to address our 10x scaling needs and applying some of these same principles to help extend our AI clusters between multiple data centers. Meta’s Backbone network is […]
Research isn’t everything. Facts alone don’t win arguments, but powerful stories do. Here’s how to turn your research into narratives that inspire trust and influence decisions.
