The best problem-solving writing in software engineering — databases, performance, security, frontend and distributed systems, in one feed.
In early 2023, Slack faced a foundational challenge: serving Large Language Models (LLMs) at enterprise scale with the security, reliability, and performance our customers expect. Over three years, we evolved from basic infrastructure to orchestrating a sophisticated multi-cloud architecture. We didn’t just want shiny new models; we needed a system resilient to regional outages and…
Seventy percent of websites still fail basic WCAG contrast checks in 2025. After years of design system tooling, accessibility linters, and JavaScript libraries, nothing moved the needle. We didn’t need better libraries. We needed better CSS. `contrast-color()` is that better CSS.
In 2025, solo founders in the top decile generated 61 times the revenue of the median solo founder in their first six months. We analyzed the data to understand what drives that gap.
Cloudflare Radar data confirms early indications of a partial Internet restoration in Iran, nearly three months after the shutdown began. Traffic spikes and DNS queries have risen, but network activity is currently just 40% of pre-shutdown levels.
“Vibe coding” - the practice of non-technical citizen builders using generative AI tools to rapidly develop applications, this has significantly accelerated software prototyping. However, because AI agents naturally prioritise the path of least resistance, they frequently recommend insecure configurations, creating systemic security exposure across industries. To combat this we need to write a sec
In a recent article about harness engineering for coding agent users, I laid out a mental model for expanding a coding agent harness: a system of guides and sensors that increase the probability of good agent outputs and enable self-correction before issues reach human eyes. This article is a more practical follow-up where I walk through my experience with using sensors that help keep the codebase
Radar now blocks high-risk transactions across all supported payment methods; defends against new fraud types; and gives platforms new tools to evaluate and mitigate merchant risk on and off Stripe.
Figma’s editorial newsletter about how products take shape—and shape our world.
There are a bunch of JavaScript animation libraries out there, and you might have wondered whether there’s a performance cost compared to traditional CSS transitions and keyframe animations. In this blog post, we’ll compare the same animation across several different strategies and see the differences firsthand. There’s some interesting nuance here!
We’re introducing SilverTorch, a reimagining of recommendation systems that unifies all retrieval components for user generated content under a unified architecture. SilverTorch shows up to 23.7x higher throughput compared to the state-of-the-art approaches. It’s also showing 20.9x more compute cost efficiency compared to a CPU-based solution while also improving accuracy. Our research paper, “Sil
Discover how to use VS Code to interact with GitHub and maintain your projects.
There’s a moment in almost every usability session where a participant pauses at the login screen, types something, and glances up: checking whether they’re “doing it right.” That pause is a clear sign. They’ve already clocked that this isn’t a real app, and every data point collected after that moment is filtered through that awareness.
Nova lets engineers run multiple coding sessions in parallel and lets internal systems use AI agents as part of automated workflows.
While everyone’s talking about “tokenmaxxing,” we’ve compiled seven best practices to help you build smarter—without prompting more—in Figma Make.
If AI can make anyone a product builder, the real edge is knowing what’s worth shipping.
We are committed to empowering every developer by building an open, secure, and AI-powered platform that defines the future of software development.
What people say, feel, think, and do are often very different things. To understand the underlying reasons for user behavior, it helps to look beyond the surface and explore hidden motivations, root causes, and the different layers of reality that shape how people act. Brought to you by Measuring UX Impact, **friendly video course on UX** and design patterns by Vitaly.
Check out these 10 open source tools that help game developers create art, animation, levels, audio, dialogue, debug UIs, and engine-ready assets.
Explore our update on GitHub’s accessibility strategy, and learn how you can join us in building a culture of accessibility.
Meet `sibling-index()` and `sibling-count()`. Staggered cascade effect in one line of CSS without `:nth-child()` rules or JS workarounds. Works for 5 items or 5,000.
GitHub Enterprise Server customers need to take immediate action.
