The best problem-solving writing in software engineering — databases, performance, security, frontend and distributed systems, in one feed.
In August, we experienced five incidents that resulted in degraded performance across GitHub services.
Workers now enables Node.js compatibility by default, supports applications up to 64 mebibytes, and adds a URL-based module registry with import.meta, lazy compilation, shared code caches, and clearer errors.
TThe web is evolving beyond menus, forms, and endless clicks toward experiences shaped around human intent. For UX designers, understanding this shift means re-evaluating their role, moving from designing visible interfaces to guiding transparent, intent-driven AI experiences.
Automatic Key Exchange probes TLS 1.3-capable customer origins to learn which key agreement algorithms they support. We then lead with the most secure algorithm when connecting to the origin, preferring post-quantum connections wherever the origin supports it.
This blog is a deep walkthrough about network policies in Kubernetes, read to know more.
Kody turns the good answer into a package you keep.
Clearing the confusion about what Bayesian A/B testing is.
In controlled offline evaluations, HydraFusion’s selective coding workflows matched or exceeded the evaluated Opus 5 baseline while reducing estimated workflow cost. Now available as a research preview in GitHub Copilot.
Use production traffic and security signals to prioritize findings, prepare edge mitigations when safe, and propose code patches. By combining WAF data with OpenAI Daybreak models, Vulnerability Discovery and Remediation helps teams identify and patch the most critical threats first.
Learn how to run parallel agents in the GitHub Copilot app, and experience the moment it stops feeling scary and starts feeling powerful.
We’re introducing ZGateway, the proxy we are using to unify traffic through ZippyDB, Meta’s most widely-used key value store. As a bonus, it also enables admission control, load balancing, cross-region resilience, and richer operations. ZippyDB is the most widely used key value store at Meta, backing product metadata, counters, and configuration, and can serve billions […]
Most of what an AI coding agent does for me isn't thinking. It's I/O.
From loop engineering to harnesses, squads, and open weights, the GitHub Podcast breaks down the AI terms showing up in developer conversations.
Why shorter outputs can cost more, and how GitHub Copilot reduces wasted work across the complete coding task.
We’ve built an AI agent that acts as a secondary expert for a given domain, making deep specialist knowledge readily available and preserved for anyone in an organization to access, share, and build upon. This is not a typical domain-specific agent. Its novelty comes from integrating two layers: A structured, auditable knowledge architecture separates what […]
River, Shopify’s AI agent in Slack, enables autonomous vulnerability remediation, not just detection.
Could we get more cache space with the same hardware? We prototyped compression inside Cloudflare's cache to find out.
This blog is about how CYPEX can cut costs on building internal tools.
Fluid is Vercel's compute architecture. One system that assembles the right machine for any workload, builds, functions, or sandboxes, and reshapes it on demand.
Bot operators have historically had the economic advantage, bypassing static, deterministic detection rules with cheap proxies and retooling. Cloudflare's new Adaptive Intelligence engine flips this dynamic by autonomously learning from the meta-signals of live traffic and deploying disposable rules, making automated attacks too expensive to sustain.
About a year ago, I was offered a presentation slot at the WeAreDevelopers World Congress in Berlin. I rarely take speaking engagements, especially international ones, but this one arrived at just the right time, the right place, and with the right person – I said yes, on the contingency that Ben Dumke-von der Ehe joins me in the presentation. Ben is an early community hire at Stack Overflow who l
The journey to create a polyfill for the upcoming CSS random() function that works in all browsers. Let’s Use the Emergent CSS random() Function in all the Browsers originally handwritten and published with love on CSS-Tricks . You should really get the newsletter as well.
