Progress Agentic RAG gets insights from your unstructured data at 80% less cost than building RAG tech yourself.

>> Automatically index enterprise sources like Google Drive, AWS S3, SharePoint, and more

>> Use 30+ advanced retrieval strategies to tune for a specific use case

>> Instantly swap between 40+ LLMs or bring their own model

>> Built-in evaluation (REMi) to measure groundedness, answer quality, and relevance

>> Operate securely at scale with built‑in governance and traceability to source files

Nango used OpenCode to develop an autonomous agent that generates hundreds of API integrations in minutes for a fraction of the traditional cost. While highly efficient, the project showed that these agents require strict guardrails and constant verification to actually be reliable and fully usable.

The VS Code team describes how AI agents enabled a shift to weekly releases by automating tasks like triage and PR generation, doubling commit volume. Maintaining high velocity requires good testing harnesses and mandatory automated reviews to prevent regressions.

Naming your useEffect callbacks instead of leaving them as anonymous arrow functions makes it easy to skim a component's intent from function names alone. The naming also acts as a design forcing function. If you can't name an effect without “and,” it's doing too much, and if the best name sounds like internal state shuffling, it probably shouldn't be an effect at all.

The article talks about ten fake conspiracy theories about open source, such as Dependabot as recruiter surveillance, Kubernetes as a Google jobs program, git as a declassified Finnish military system, and more.

Complex and manual setup instructions for AI coding agents, requiring users to edit configuration files, are a major barrier to product adoption. A better solution is a single command that scans a user's machine, writes the necessary agent configurations, and installs agent skills to teach agents how to use the tool directly.

Don't use LLMs to write documents. Doing so is a missed opportunity for personal growth and a betrayal of professional trust. Writing is a cognitive exercise necessary for developing a deep understanding of topics.

Logging libraries provide structured outputs so you and your AI agents see what actually needs fixing. In this Sentry blog, you'll get a side-by-side comparison of the top JavaScript logging libraries to find the best fit for your use case. Read the blog

The Codex plugin integrates OpenAI's Codex into Claude Code, allowing users to perform advanced code reviews and delegate tasks like bug fixes via background jobs. It uses existing Codex CLI configurations to provide an easy workflow for the combo.

Semiotic is a React data visualization library that provides a broad range of standard and advanced chart types, including complex network, streaming, and real-time geographic visualizations. The library is specifically designed for AI-assisted development, with machine-readable schemas and diagnostic tools to help coding assistants generate accurate chart code.

AI-generated slop is overwhelming open-source software maintainers. An influx of poor contributions undermines the collaborative model, introduces security risks, and makes open-source projects unsustainable, forcing some to shut down. Maintainers are implementing stricter AI policies as a result.

AI coding agents will transform vulnerability research and exploit development by using LLMs to discover high-severity vulnerabilities across software faster than ever. This means that there will also be an overwhelming amount of zero-day exploits in networked devices.

As the first engineer on TLDR's new Applied AI team, you'll build AI agents to automate end-to-end workflows and lead our context engineering project to allow non-technical teammates create their own AI workflows. Learn more.

Motivated by a potential ban on new consumer routers, this guide shows how to turn virtually any Linux-compatible computer, even old or "junk" hardware, into a fully functional and customizable home network router using free and open-source software.

Following developer backlash, GitHub reversed its decision to allow Copilot to automatically insert promotional "tips" (ads) into users' pull requests.

After a technical draft was rejected for sounding AI-generated, this person felt that reliance on LLMs has eroded her natural writing voice and creativity.

This dev created a forked Excalidraw VSCode extension to automatically generate light and dark mode SVG images from framed elements in his Excalidraw files.
