9 months ago, Sourcegraph launched Amp as an experimental coding agent - and it quickly grew to become one of the leading coding agents.

Today, Amp has become its own company - operating at the frontier of software development. Amp is now a separate (profitable) business, with a dedicated team focused on exploring the boundaries of software development to see what's possible.

Google Maps algorithms influence London's restaurant scene as it acts as a “market maker,” using prominence signals that create a cumulative advantage for some restaurants. This was done by scraping data from over 13,000 establishments and building a machine-learning model. To counter this, this dev developed a dashboard that identifies "underrated gems" by calculating the divergence between a restaurant's actual rating and its algorithmically predicted performance.

Despite widgets requiring native Swift code, you can use Expo and the `@bacons/apple-targets` plugin to integrate them together. This setup allows the React Native app and Swift widget to share data via App Groups and deep link back to the main app for expanded features.

The one core skill that separates senior engineers from everyone else is the ability to reduce ambiguity. Senior engineers ask questions nobody else asks, separate what matters from the noise, and identify what should be done now. They're worth their salaries because they derisk projects. When senior engineers do this well, it looks easy.

Getting a Google Gemini 3 Pro API key in the Google Cloud Console is unintuitive. This is because Google Cloud has many identically named products, a complex billing setup, and an identity verification process.

Let users authenticate with their Vercel accounts. Setup takes minutes: create an integration in Vercel's developer settings, add credentials to Clerk, and enable it in your sign-in component. Ideal for tools that integrate with Vercel's API or target the Vercel ecosystem. Full setup guide in our docs.

Amazon EC2 M9g instances offer the best price performance for general-purpose workloads.

Nucleate is an AI-powered platform that lets users build, customize, and export beautiful, production-ready React Native mobile apps from plain English descriptions. It has support for cloning, forking, and exporting apps, along with basic design system integration.

Python Workers allow Python developers to ship Python globally in less than two minutes in a single command. Python Workers now supports any package supported by Pyodide, the WebAssembly runtime that powers Python Workers. It also now has dedicated memory snapshots to reduce cold start times. This post shares some of the technical details behind the changes.

Building something is a great way to learn. This developer rebuilt Turbopuffer, a vector database built entirely on object storage, to understand the tradeoffs made in its development. The post follows along as they figure out how to build a vector database from first principles.

A survey by Stack Overflow explored developer frustrations amidst increasing AI adoption, finding that 84% currently use or plan to use AI, mainly for coding, searching, and debugging. However, developer problems aren't mainly from coding tasks themselves or AI's shortcomings, but rather from a lack of adequate and accessible documentation. Tasks like learning new codebases, deployments, and handling support tickets become frustrating due to fragmented and bad documentation efforts.

Test automation efforts often fail. So shift your approach. QualityLogic's TestNitro delivers 100% automatable Playwright coverage in weeks, code in your repo (no lock-in). Tests added + maintained each sprint and only human-verified defects reported. Finally, test automation that works.

VoxCSS is a CSS voxel engine that renders customizable, interactive 3D grids of HTML cuboids in the DOM.

The Rust experiment in the Linux kernel has concluded, as Rust is now considered a core and permanent part of the kernel.

There are numerous historical design mistakes in CSS.

Wirebrowser is a debugging, interception, and memory-inspection toolkit powered by the Chrome DevTools Protocol that unifies network manipulation, API testing, automation scripting, and deep JavaScript memory inspection into one interface.
