How to Selectively Route OpenWrt Traffic Through OpenVPN Using Passwall2

·1 views

A technical guide outlines how to configure an OpenWrt router to selectively route traffic through an OpenVPN connection rather than tunneling all traffic by default. The setup requires installing luci-app-openvpn, openvpn-openssl, Passwall2, and Singbox packages on the router. Users must add the 'route-nopull' option to their OpenVPN config and create an unmanaged network interface mapped to the tun0 device, while skipping default firewall rule modifications. A Singbox node is then configured in Passwall2 using the custom tun0 interface, enabling the VPN to function as a selective proxy or network-wide SOCKS proxy. Multiple VPN configurations can be supported simultaneously by assigning additional tunnel interfaces such as tun1 or tun2 and creating corresponding Passwall2 nodes.

Computer Use Demos Impress, But May Signal AI Interface Design Is Stuck

Computer use agents that navigate websites and complete tasks via plain-language commands remain the most compelling demonstrations in AI today. However, a growing critique suggests these workflows are fundamentally retrofitted, forcing a new technology paradigm into outdated interface conventions. Typed chat has been the default gateway to AI for three years, but it may not be the long-term solution for interacting with advanced intelligence. Having AI agents mimic human mouse movements and keystrokes is seen as a temporary bridge rather than a sustainable design direction. As AI adoption matures, experts argue that rethinking interaction and interface design should become a central industry priority.

Developer releases zero-dependency React rich text editor as open-source npm package

A developer named Elango has published react-lite-rich-text-editor, a lightweight WYSIWYG editor for React applications that relies solely on native browser APIs with no external dependencies. The package was created to address common trade-offs with popular editors like Draft.js, Quill, Slate, and TipTap, including large bundle sizes and complex setup requirements. The editor supports rich text formatting, headings, lists, tables, image uploads with drag-to-resize, video embeds from platforms like YouTube and Vimeo, and markdown shortcuts. It is compatible with React 16 and above, requires minimal configuration, and returns content as an HTML string via an onChange callback. The package is available on npm under the name react-lite-rich-text-editor, with source code hosted publicly on GitHub.

Five configuration checks to fix OpenAI-compatible API integration failures

Most failures when integrating OpenAI-compatible APIs stem from configuration mismatches rather than SDK bugs. Developers should verify the base URL, API key, and exact model ID before writing any application code. Running a minimal cURL request first helps confirm the setup works independently of frameworks like LangChain or Dify. Reviewing request logs for model used, token count, failure reason, and cost can catch silent misrouting issues. The most frequent error is updating only the base URL while leaving an outdated key or model alias in place, often triggering 401 errors or unexpected charges.

Backpropagation Is Just Dynamic Programming (I Animated It to Prove It)

Everyone learns backpropagation as "apply the chain rule." Almost nobody explains why it's fast — and that "why" is the whole reason deep learning is computationally possible at all. So I animated one full training step to show the part most explanations skip. What you're actually seeing Forward pass: a single signal travels through 3 weights → a prediction → compared to the target = the loss. Backward pass: the error (δ) flows back through the network. δ₃ is computed at the output, then reused to get δ₂, which is reused to get δ₁ — never recalculated from scratch.
