The best problem-solving writing in software engineering — databases, performance, security, frontend and distributed systems, in one feed.


Magic Transit customers can now program their own DDoS mitigation logic and deploy it across Cloudflare’s global network. This enables precise, stateful mitigation for custom and proprietary UDP protocols.

A demonstration of how to setup a Patroni standby cluster, including prerequisites, configuration and promotion.

I used coding agents to build agents that automated part of my job. Here’s what I learned about working better with coding agents.

Meta continues to lead the industry in utilizing groundbreaking AI Recommendation Systems (RecSys) to deliver better experiences for people, and better results for advertisers. To reach the next frontier of performance, we are scaling Meta’s Ads Recommender runtime models to LLM-scale & complexity to further a deeper understanding of people’s interests and intent. This increase […]

The Problem: Legacy Tooling and Its Limitations Currently, Slack utilizes a hybrid approach to network measurement, incorporating both internal (such as traffic between AWS Availability Zones) and external (monitoring traffic from the public internet into Slack’s infrastructure) solutions. These tools comprise a combination of commercial SaaS offerings and custom-built network testing solutions de

With the new month just around the corner, could there be a better occasion to freshen up your desktop? If you’re looking for some unique and inspiring wallpapers to accompany you on all those adventures that April may bring — and maybe spark some new ideas, too — well, this post has got you covered.


We are opening our advanced Client-Side Security tools to all users, featuring a new cascading AI detection system. By combining graph neural networks and LLMs, we've reduced false positives by up to 200x while catching sophisticated zero-day exploits.

Learn how to secure your projects and keep them safe with GitHub Advanced Security.

Meta is continuing its long-term roadmap to help the construction industry leverage AI to produce high-quality and more sustainable concrete mixes, as well as those exclusively produced in the United States. Concurrent with the 2026 American Concrete Institute (ACI) Spring Convention, Meta is releasing a new AI model for designing concrete mixes – Bayesian Optimization […]

Turborepo 2.9 is up to 96% faster than Turborepo 2.8. Here's how we did it, using coding agents, a human in the loop, and Vercel Sandboxes.

Workflows are now visualized via step diagrams in the dashboard. Here’s how we translate your TypeScript code into a visual representation of the workflow.

Discover some of the interesting features that have landed in stable and beta web browsers during March 2026.

When we investigated why our Atlantis instance took 30 minutes to restart, we discovered a bottleneck in how Kubernetes handles volume permissions. By adjusting the fsGroupChangePolicy, we reduced restart times to 30 seconds.

Looking at research and experiments that are designed to automatically generate user interfaces based on user preferences.

A look at GitHub Actions’ 2026 roadmap, outlining how secure defaults, policy controls, and CI/CD observability harden the software supply chain end to end.

Reviewed advisories hit a four-year low, malware advisories surged, and CNA publishing grew—here’s what changed and what it means for your triage and response.

Success in modern UX isn’t about having the most content. It’s about having the most findable content. Yet even with more data and better tools than ever, internal search often fails, leaving users to rely on global search engines to find a single page on a local site. Why does the “Big Box” still win, and how can we bring users back?

This is the story of how we built FigCache, a foundational technology that underpins a reimagined internal platform for ephemeral data.

From April 24 onward, interaction data—specifically inputs, outputs, code snippets, and associated context—from Copilot Free, Pro, and Pro+ users will be used to train and improve our AI models unless they opt out.

We’re introducing Dynamic Workers, which allow you to execute AI-generated code in secure, lightweight isolates. This approach is 100 times faster than traditional containers, enabling millisecond startup times for AI agent sandboxing.


Learn how to integrate the Copilot SDK into a React Native app to generate AI-powered issue summaries, with production patterns for graceful degradation and caching.
