TLDR WEB DEV 2025-08-21

INTRODUCTION TO AT PROTOCOL

The Authenticated Transfer Protocol (ATProto) is the underlying technology of Bluesky. This article describes the core components of ATProto, including records, blobs, lexicons, DIDs, handles, and AT URIs, outlining how they structure data and identify users. It also goes over the server architecture, focusing on the roles of PDSes (Personal Data Servers), relays, AppViews, labellers, and feed generators in processing and distributing data across the network.

HOW I BUILT A FULL-STACK REACT FRAMEWORK 4X FASTER THAN NEXT.JS WITH 4X MORE THROUGHPUT

Rari is a full-stack React framework built on a custom Rust runtime with V8. Its architecture consists of three layers: a Rust core runtime for executing React Server Components, smart Vite integration for RSC-aware transformations and dependency management, and true server-side rendering with streaming support. It uses file-based routing with automatic code splitting and prefetching, optimizing bundle sizes and performance.

STATE MANAGEMENT ARCHITECTURE IN NX

Nx and NgRx Signal Store provide a structured approach to Angular application state management. The architecture in this article goes over a library-based structure with clear separation of concerns between data access, state management, UI, and features. It enforces dependency rules to prevent architectural drift and allows benefits like build optimization, testing isolation, and team scalability.

AWS IN 2025: THE STUFF YOU THINK YOU KNOW THAT'S NOW WRONG

Security configurations can now be altered live in EC2. Instance reliability has improved a lot, and Spot Instance pricing is less volatile. S3 now has read-after-write consistency, deprecated ACLs, and simpler Glacier integration. AWS networking has been updated with better VPC options, quicker CloudFront updates, and advancements in load balancing.

WHY I'M ALL-IN ON ZEN BROWSER

This dev switched to Zen Browser after being disappointed with Arc's shift to an AI-focused browser called Dia, which lacked the power-user features he valued. He found Dia's privacy concerns and increased competition unappealing. While Firefox is a reliable option, Zen Browser offers a more streamlined, Arc-inspired UI with customizable features built on top of the Firefox framework.

big! Registration closes soon

ZEDLESS

Zedless is a fork of the Zed editor with a focus on privacy and local-first functionality. It removes reliance on cloud services, removes telemetry, and prioritizes user-configurable infrastructure with disabled-by-default network features.

HERB

Herb is an ecosystem of developer tools designed to improve the experience of working with HTML+ERB templates through accurate parsing. The core of Herb is a fast, portable, HTML-aware ERB parser written in C that generates a detailed syntax tree. This ecosystem includes tools such as a language server, formatter, and linter, integrating into editors and CI pipelines.

TIDEWAVE WEB: IN-BROWSER CODING AGENT FOR RAILS AND PHOENIX

Tidewave Web is a new in-browser coding agent for Rails and Phoenix web applications that runs directly in the development environment. Unlike traditional coding agents, it provides shared context by understanding the UI state, framework, and accessing developer tools like the database and logs. This removes the need for constant back-and-forth between the developer and the agent.

DRIVING AI ADOPTION AT DROPBOX: A CONVERSATION WITH CTO ALI DASDAN

Dropbox had over 90% AI adoption among its engineering teams in 2025 due to strong leadership alignment and a culture of knowledge-sharing. The company uses a hybrid approach of both external AI tools like GitHub Copilot and internally-built custom solutions to address specific needs in coding, code reviews, testing, and debugging.

“AI FIRST” AND THE BUS FACTOR OF 0

The "Bus Factor" measures the risk of losing knowledge if key team members leave. With the rise of "AI first" approaches using tools like ChatGPT, many people are becoming comfortable with a Bus Factor of zero, where no one understands the AI-generated code. This reliance on LLMs for code generation makes maintaining and debugging software extremely difficult.

SEQUOIA BACKS ZED'S VISION FOR COLLABORATIVE CODING

Zed is a coding platform that raised $32M in Series B funding led by Sequoia Capital. Its goal is to create an IDE where code discussions are directly linked to the code, addressing the limitations of current snapshot-based systems like Git. Zed is developing DeltaDB, a new operation-based version control system that tracks every edit, allowing for real-time collaboration with both humans and AI agents.

CLAUDIA

Claudia is a desktop application that provides a GUI for managing Claude Code sessions, creating custom agents, tracking usage, and offering project management features.

AGENTS.MD

AGENTS.md is a simple, open-source Markdown file used by AI coding agents to understand project context, setup, coding style, testing, and PR guidelines.

COPILOT BROKE YOUR AUDIT LOG, BUT MICROSOFT WON'T TELL YOU

Microsoft's Copilot AI tool had a vulnerability that allowed users to access files without leaving a trace in the audit log, but despite fixing the issue, Microsoft chose not to disclose it to customers.

NESTABLE

Nestable is a tool that allows users to create infinitely nested pages/canvases, search across content, deep link to specific elements, and import/export their work.
