The caller ID company says users are increasingly ignoring and blocking calls from India's dedicated business number series.
When I read papers, I have to jump between multiple tabs to find the dataset, code, videos, peer reviews, and so on. I tried to fix this with this project. It started as a project just for papers on arXiv, but after its initial success on Twitter (got like 1.9k views: the most I have gotten for a post), I have now expanded it to include other openly available papers from PubMed Central, bioRxiv, medRxiv, and eLife. These papers have been linked with their genes, proteins, diseases, drugs, clinic

Introduction: Unveiling littlebag Meet littlebag , a reactive UI framework that defies conventional expectations by packing essential features into a mere 343 bytes (minified and brotlified). This isn’t just a technical curiosity—it’s a proof of concept that challenges the notion that UI frameworks must be bloated to be functional. littlebag includes: Reactive state management via state and effect , enabling dynamic updates without manual DOM manipulation. An html element factory that inherently supports reactivity, reducing boilerplate code. Conditional rendering with keyed , allowing efficient updates to specific UI segments. Reactive lists using each , simplifying the handling of dynamic data collections. TypeScript declarations , ensuring type safety and developer productivity. The framework’s size is achieved through aggressive tree-shaking and code minimization , stripping away all non-essential logic. However, this comes at a cost: performance limitations due to the absence of optimizations like virtual DOM diffing or batch updates . Each reactive update triggers direct DOM manipulation, which can lead to layout thrashing —a mechanical process where frequent reflows and repaints cause frame rate drops, making the UI feel sluggish. Inspired by VanJS (1 kB) and its dependency on an additional 1.2 kB library (Van X), littlebag aims to eliminate such overhead. Yet, its current state is experimental. Without user feedback, it risks remaining a niche project, failing to address its performance bottlenecks or evolve into a viable alternative to larger frameworks. The creator’s plan to add Server-Side Rendering (SSR) hinges on community interest, but SSR itself introduces complexity—requiring a custom DOM implementation to avoid client-side hydration costs. If users engage, littlebag could become a lightweight SSR solution; if not, it may stagnate as a curiosity. The stakes are clear: littlebag’s utility depends on whether it can balance its minimalism with practical
Quick note before we dive in — I know I've been off track from the iOS/Swift series lately. I just...
I just submitted another Chrome extension to the Chrome Web Store. I have submitted multiple extensions overtime. Mostly for my own tooling and community share or just because idea was fun. The first time took 3 attempts. The second time I got rejected in 12 hours for something completely avoidable. Here's every gotcha I hit — so you don't have to. 1. Manifest description has a 132-character hard limit Not documented prominently anywhere. You'll get a cryptic upload error: "The description field in manifest is too long." Your package.json description or wxt.config.ts description gets baked into manifest.json — check it BEFORE you zip. Fix : Count characters. 132 max. Put the detailed description in the CWS form, not the manifest. 2. Don't put a "Keywords:" line in your description I literally had: Keywords: pinterest seo, pin score, pin quality, pinterest optimizer... Rejected within 12 hours for "Keyword Spam." CWS explicitly bans keyword lists in descriptions — even if they're relevant. Your keywords should be woven naturally into prose. Fix : Write human sentences that include your keywords. "Score your Pinterest pin quality before publishing" contains 3 keywords naturally. 3. upload-artifact@v4 silently skips hidden directories If your build tool outputs to .output/ (like WXT does), GitHub Actions' upload-artifact won't find it. The glob path: .output/*.zip returns nothing because .output starts with a dot. Fix : Add include-hidden-files: true to your upload-artifact step. - uses : actions/upload-artifact@v4 with : path : .output/*.zip include-hidden-files : true 4. optional_permissions need justification too I added sidePanel as an optional permission (reserved for a future feature). CWS asked me to justify it. Optional doesn't mean invisible to reviewers. Fix : Add a justification for EVERY permission — required AND optional. Explain what it'll do and why it's optional. 5. "Support URL" is not your email address The form has separate fields: Support email : yo
The Problem: Why Most Telegram Payment Bots Fail You've built a Telegram bot that sells digital courses, takes coffee orders, or offers freelance services. Traffic is flowing. But when your bot tries to collect payment, you hit a wall: Payment gateways demand hefty setup fees and compliance audits You end up holding customer money in an intermediary account (legal liability) Settlement takes 3–5 days, frustrating both you and buyers Integration is a maze of webhooks, IPNs, and error handling A founder we know spent two weeks wrestling with Stripe's Telegram integration, only to discover the monthly fee ate 40% of his margins on $2–5 transactions. He needed something lighter, faster, and truly peer-to-peer. Enter AgentPay VN : an open-source Python SDK that lets your Telegram bot generate QR codes pointing directly to your bank account. No middleman. No holding funds. Just instant VietQR payments via the banking system Vietnameses already use daily. What Is AgentPay VN? AgentPay VN is an MIT-licensed Python SDK + MCP server that orchestrates VietQR payment requests. Here's the mental model: You create a payment request in your bot (e.g., "Customer ordered coffee for 50,000 VND") AgentPay generates a checkout URL with an embedded QR code Customer scans → pays → bank confirms settlement in seconds Your bot receives a webhook callback and fulfills the order The key: AgentPay never touches money . The QR points straight at your merchant bank account. A bank feed confirms settlement. You own the transaction end-to-end. Why Telegram + VietQR? Telegram has 180+ million users , with especially strong adoption in Southeast Asia. Vietnamese merchants already use banking apps (MB Bank, Techcombank, VCB) that natively support VietQR scanning. Your bot becomes a natural extension of their daily workflow: Customer receives a payment link in chat Opens the QR code (in-app or screenshot) Scans with their banking app (2–3 taps) Money clears to your account in minutes Bot auto-confirm
