[Other] Show HN: Sinkzone DNS – Forwarder that blocks everything except your allowlist Most site blockers work by blacklisting distractions. That never worked for me, the internet is too big, and there’s always something new to waste time on.<p>I wanted the opposite: allowlist‑only browsing. Block everything by default, and explicitly allow only what I need.<p>So I built Sinkzone: a local DNS forwarder with two modes:<p>Monitor mode: lets all traffic through, but logs every domain so you can decide what to allow.<p>Focus mode: only allowlisted domains resolve; everything else is blocked (NXDOMAIN).<p>It’s open source, written in Go, and runs locally on macOS, Linux, and Windows. Works a bit like Pi‑hole, but instead of blocking ads, it blocks everything unless you say otherwise.<p>I’m curious if this would be useful in your workflow. If you try it, please let me know what breaks, what works well, and what you’d improve.

[Other] Show HN: An Open-Source E-Book Reader for Conversational Reading with an LLM Hi HN! I&#x27;ve been working on BookWith, an open-source e-book reader that integrates AI as your reading companion.<p>The problem: Traditional e-readers are passive. When you encounter something unclear, you have to context-switch to search for it. Your highlights and notes remain isolated, and you can&#x27;t easily connect ideas across different books.<p>My solution: BookWith embeds an AI that maintains full context of what you&#x27;re reading. It features:<p>- Context-aware AI chat: Ask questions about the current page&#x2F;chapter and get instant answers<p>- AI podcast generation: Automatically converts book content into conversational podcasts using Google Cloud TTS<p>- Multi-layer memory system: Short-term (last 5 conversations), mid-term (summarized every 20), and long-term (vector search) memory that maintains continuity across reading sessions<p>- Smart annotations: 5-color highlighting system that AI can reference and analyze<p>Technical stack: Built as a fork of Flow (epub reader), with added LLM integration and vector database for semantic search. Supports multiple LLMs and languages (EN&#x2F;JA&#x2F;ZH).

[Other] Show HN: HMPL – Small Template Language for Rendering UI from Server to Client Hi HN! Together with contributors, we&#x27;ve been making a small template language for a year now, which, in our opinion, can replace HTMX and Alpine.js. It is a mix between EJS and Handlebars, that is, you can make a request with a familiar syntax to the server in HTML right in the markup.<p>Requests are made via fetch and are configured via javascript almost entirely, which is what is needed today to work with the server.<p>The very essence of the template language comes down to minimizing the size of the bundle of the original web application by moving the components to the server and then storing them there. Thus, on the client we get a framework, where we insert components from the server brick by brick.<p>We showed this template language a long time ago, but it was not so mature then, so people had a lot of questions: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41204552">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41204552</a><p>Thank you very much to everyone for your attention! Please tell me what you think about the project? It will be interesting to know!
