[Other] Show HN: AICF – a tiny "what changed" feed for AI/RAG (v0.1 minimal core) I’m proposing AICF (AI Changefeed) — a minimal, web-native way for sites to expose append-only change events. Instead of crawlers or RAG systems re-embedding everything, they can refresh only the sections that changed.<p>Discovery: a &#x2F;.well-known&#x2F;ai-changefeed JSON points to a feed.<p>Feed: an append-only NDJSON file with just 4 required fields (id, action, url, time) plus optional hints (anchor, checksum, note).<p>Goal: cut wasted crawling&#x2F;embedding while keeping docs&#x2F;pricing&#x2F;policy pages fresh for AI&#x2F;agents.<p>Spec &amp; examples here: <a href="https:&#x2F;&#x2F;github.com&#x2F;mnswdhw&#x2F;AICF&#x2F;blob&#x2F;main&#x2F;spec&#x2F;AICF-v0.1.md" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mnswdhw&#x2F;AICF&#x2F;blob&#x2F;main&#x2F;spec&#x2F;AICF-v0.1.md</a><p>Would love feedback: is the minimal core (anchors only, no chunks&#x2F;vectors&#x2F;push yet) the right starting point? Would you use this in your docs&#x2F;RAG stack?

[Other] Show HN: JavaScript-free (X)HTML Includes (spoiler: its XSLT)<p>I&#x27;ve been working on a little demo for how to avoid copy-pasting header&#x2F;footer boilerplate on a simple static webpage. My goal is to approximate the experience of Jekyll&#x2F;Hugo but eliminate the need for a build step before publishing. This demo shows how to get basic templating features with XSL so you could write a blog post which looks like<p><pre><code> &lt;?xml version=&quot;1.0&quot;?&gt; &lt;?xml-stylesheet type=&quot;text&#x2F;xsl&quot; href=&quot;&#x2F;template.xsl&quot;?&gt; &lt;page&gt; &lt;title&gt;My Article&lt;&#x2F;title&gt; &lt;content&gt; some content &lt;ul&gt; &lt;li&gt;hello&lt;&#x2F;li&gt; &lt;li&gt;hello&lt;&#x2F;li&gt; &lt;&#x2F;ul&gt; &lt;&#x2F;content&gt; &lt;&#x2F;page&gt; </code></pre> Some properties which set this approach apart from other methods:<p><pre><code> - no build step (no need to setup Jekyll on the client or configure Github&#x2F;Gitlab actions) - works on any webserver (e.g. as opposed to server-side includes, actions) - normal looking URLs (e.g. `example.com&#x2F;foobar` as opposed to `example.com&#x2F;#page=foobar`) </code></pre> There&#x27;s been some talk about removing XSLT support from the HTML spec [0], so I figured I would show this proof of concept while it still works.<p>[0]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44952185">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44952185</a><p>See also: grug-brain XSLT <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44393817">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44393817</a>

[Other] Show HN: AIMless – a 10 KB single file P2P chat app with zero dependencies I built AIMless, a ridiculously minimalistic, browser native chat app that fits entirely into one HTML file (10 KB). It’s decentralized, P2P, and has no build tools, no server, and no frameworks. Just you, your browser, and a copy&#x2F;pasted blob or two.

[Other] Show HN: I integrated my from-scratch TCP/IP stack into the xv6-riscv OS Hi HN,<p>To truly understand how operating systems and network protocols work, I decided to combine two classic learning tools: the xv6 teaching OS and a from-scratch TCP&#x2F;IP stack.<p>I&#x27;m excited to share the result: my own from-scratch TCP&#x2F;IP networking stack running directly inside the xv6-riscv (<a href="https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;xv6-riscv-net" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;xv6-riscv-net</a>) kernel.<p>The project uses a modern virtio-net driver, allowing it to run seamlessly in QEMU and communicate with the host machine.<p>Key features:<p>- From-Scratch Stack: The core is powered by microps (<a href="https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;microps" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;microps</a>), a TCP&#x2F;IP stack I originally wrote to run in user-space as a personal project to learn the low-level details of networking.<p>- Kernel Integration: This project ports microps from user-space into the xv6-riscv kernel.<p>- Socket API: Implements standard system calls (socket, bind, accept, etc.) to enable network application development.<p>- User-level Tools: Comes with a simple ifconfig command, plus tcpecho and udpecho servers to demonstrate its capabilities.<p>This has been a fantastic learning experience. My goal was to demystify the magic behind network-aware operating systems by building the components myself.<p>I&#x27;d love to hear your feedback and answer any questions!

[Other] Show HN: Claudable – OpenSource Lovable that runs locally with Claude Code Hey, HN! I&#x27;m Aaron. I built an open-source Lovable for Claude Code users.<p>Platforms like Lovable, Replit Agent, and Bolt require separate API keys and $25+&#x2F;month subscriptions. But if you’re already subscribed to Claude Pro or Cursor, you can use those plans directly without extra costs.<p>Claudable runs entirely locally through Claude Code (Cursor CLI also supported) and provides:<p>- Instant UI preview (similar to Lovable)<p>- Web-optimized, production-ready designs<p>- Direct Git integration<p>- One-click Vercel deployment<p>- Zero additional API costs<p>It’s open source and available today. I’m actively developing it and would love community feedback on what features to prioritize next.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;opactorai&#x2F;Claudable" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;opactorai&#x2F;Claudable</a><p>Happy to answer any questions!
