Welcome to this week's Top 7, where the DEV editorial team handpicks their favorite posts from the previous week.
Congrats to all the authors that made it onto the list 👏
@kayleecodez walks us through building Conflux, a real-time collaboration engine in Rust. She explains how CRDTs (Conflict-free Replicated Data Types) eliminate merge conflicts by sending instructions rather than complete file states, making concurrent editing seamless.
@sagi0312 delivers a humorous tour of React 19.2, personifying the framework as a self-aware millennial in its "sigma era." She breaks down new features like the component and useEventEffect hook with witty analogies that make the updates easier to understand.
@narnaiezzsshaa challenges the tech industry's obsession with the "expert" label, arguing that true competence lies in acknowledging what you don't know. They propose a shift from performing expertise to demonstrating competence, using their own experience in cybersecurity to illustrate how intellectual humility is a crucial diagnostic tool.
Setting up an encrypted secondary drive on Linux
Mike Rispoli ・ Nov 10
@mrispoli24 provides a step-by-step guide for setting up a fully encrypted secondary drive on Arch Linux using LUKS and btrfs. The tutorial is designed to be beginner-friendly, carefully explaining each command for partitioning, encryption, and automatic mounting to ensure data is secure yet convenient to access.
@asafaeirad explores why generative AIs struggle with CSS, pointing to its context-dependent nature, the separation from HTML, and the lack of a single standardized methodology. They argue that utility-first frameworks like Tailwind CSS succeed with AI because they colocate style and structure, creating the predictable patterns that models thrive on.
@varshithvhegde shares a personal story of a production failure to argue that relying solely on unit tests provides a false sense of security. They advocate for a balanced testing pyramid, emphasizing developers should stop chasing 100% code coverage and instead focus on "confidence coverage" through a mix of unit, integration, and E2E tests.
@macd0 walks developers through building a searchable podcast knowledge base using the Gemini File Search Tool. The tutorial demonstrates how to ingest an RSS feed, transcribe audio episodes, and index the content with metadata to create a RAG-enabled system without manually managing a vector database.
