[Other] Show HN: Mystral Native – Run JavaScript games natively with WebGPU (no browser) Hi HN, I&#x27;ve been building Mystral Native — a lightweight native runtime that lets you write games in JavaScript&#x2F;TypeScript using standard Web APIs (WebGPU, Canvas 2D, Web Audio, fetch) and run them as standalone desktop apps. Think &quot;Electron for games&quot; but without Chromium. Or a JS runtime like Node, Deno, or Bun but optimized for WebGPU (and bundling a window &#x2F; event system using SDL3).<p>Why: I originally started by starting a new game engine in WebGPU, and I loved the iteration loop of writing Typescript &amp; instantly seeing the changes in the browser with hot reloading. After getting something working and shipping a demo, I realized that shipping a whole browser doesn&#x27;t really work if I also want the same codebase to work on mobile. Sure, I could use a webview, but that&#x27;s not always a good or consistent experience for users - there are nuances with Safari on iOS supporting WebGPU, but not the same features that Chrome does on desktop. What I really wanted was a WebGPU runtime that is consistent &amp; works on any platform. I was inspired by deno&#x27;s --unsafe-webgpu flag, but I realized that deno probably wouldn&#x27;t be a good fit long term because it doesn&#x27;t support iOS or Android &amp; doesn&#x27;t bundle a window &#x2F; event system (they have &quot;bring your own window&quot;, but that means writing a lot of custom code for events, dealing with windowing, not to mention more specific things like implementing a WebAudio shim, etc.). So that got me down the path of building a native runtime specifically for games &amp; that&#x27;s Mystral Native.<p>So now with Mystral Native, I can have the same developer experience (write JS, use shaders in WGSL, call requestAnimationFrame) but get a real native binary I can ship to players on any platform without requiring a webview or a browser. No 200MB Chromium runtime, no CEF overhead, just the game code and a ~25MB runtime.<p>What it does: - Full WebGPU via Dawn (Chrome&#x27;s implementation) or wgpu-native (Rust) - Native window &amp; events via SDL3 - Canvas 2D support (Skia), Web Audio (SDL3), fetch (file&#x2F;http&#x2F;https) - V8 for JS (same engine as Chrome&#x2F;Node), also supports QuickJS and JSC - ES modules, TypeScript via SWC - Compile to single binary (think &quot;pkg&quot;): `mystral compile game.js --include assets -o my-game` - macOS .app bundles with code signing, Linux&#x2F;Windows standalone executables - Embedding API for iOS and Android (JSC&#x2F;QuickJS + wgpu-native)<p>It&#x27;s early alpha — the core rendering path works well &amp; I&#x27;ve tested on Mac, Linux (Ubuntu 24.04), and Windows 11, and some custom builds for iOS &amp; Android to validate that they can work, but there&#x27;s plenty to improve. Would love to get some feedback and see where it can go!<p>MIT licensed.<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;mystralengine&#x2F;mystralnative" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mystralengine&#x2F;mystralnative</a><p>Docs: <a href="https:&#x2F;&#x2F;mystralengine.github.io&#x2F;mystralnative&#x2F;" rel="nofollow">https:&#x2F;&#x2F;mystralengine.github.io&#x2F;mystralnative&#x2F;</a>

[Other] Show HN: I built a CSV parser to try Go 1.26's new SIMD package Hey HN,<p>A CSV parser using Go 1.26&#x27;s experimental simd&#x2F;archsimd package.<p>I wanted to see what the new SIMD API looks like in practice. CSV parsing is mostly &quot;find these bytes in a buffer&quot;—load 64 bytes, compare, get a bitmask of positions. The interesting part was handling chunk boundaries correctly (quotes and line endings can split across chunks).<p>- Drop-in replacement for encoding&#x2F;csv - ~20% faster for unquoted data on AVX-512 - Quoted data is slower (still optimizing) - Scalar fallback for non-AVX-512<p>Requires GOEXPERIMENT=simd.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;nnnkkk7&#x2F;go-simdcsv" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;nnnkkk7&#x2F;go-simdcsv</a><p>Feedback on edge cases or the SIMD implementation welcome.

[Database] Show HN: ShapedQL – A SQL engine for multi-stage ranking and RAG Hi HN,<p>I’m Tullie, founder of Shaped. Previously, I was a researcher at Meta AI, worked on ranking for Instagram Reels, and was a contributor to PyTorch Lightning.<p>We built ShapedQL because we noticed that while retrieval (finding 1,000 items) has been commoditized by vector DBs, ranking (finding the best 10 items) is still an infrastructure problem.<p>To build a decent for you feed or a RAG system with long-term memory, you usually have to put together a vector DB (Pinecone&#x2F;Milvus), a feature store (Redis), an inference service, and thousands of lines of Python to handle business logic and reranking.<p>We built an engine that consolidates this into a single SQL dialect. It compiles declarative queries into high-performance, multi-stage ranking pipelines.<p>HOW IT WORKS:<p>Instead of just SELECT <i>, ShapedQL operates in four stages native to recommendation systems:<p>RETRIEVE: Fetch candidates via Hybrid Search (Keywords + Vectors) or Collaborative Filtering. FILTER: Apply hard constraints (e.g., &quot;inventory &gt; 0&quot;). SCORE: Rank results using real-time models (e.g., p(click) or p(relevance)). REORDER: Apply diversity logic so your Agent&#x2F;User doesn’t see 10 nearly identical results.<p>THE SYNTAX: Here is what a RAG query looks like. This replaces about 500 lines of standard Python&#x2F;LangChain code:<p>SELECT item_id, description, price<p>FROM<p><pre><code> -- Retrieval: Hybrid search across multiple indexes search_flights(&quot;$param.user_prompt&quot;, &quot;$param.context&quot;), search_hotels(&quot;$param.user_prompt&quot;, &quot;$param.context&quot;) </code></pre> WHERE<p><pre><code> -- Filtering: Hard business constraints price &lt;= &quot;$param.budget&quot; AND is_available(&quot;$param.dates&quot;) </code></pre> ORDER BY<p><pre><code> -- Scoring: Real-time reranking (Personalization + Relevance) 0.5 * preference_score(user, item) + 0.3 * relevance_score(item, &quot;$param.user_prompt&quot;) </code></pre> LIMIT 20<p>If you don’t like SQL, you can also use our Python and Typescript SDKs. I’d love to know what you think of the syntax and the abstraction layer!</i>

[Other] Show HN: Build Web Automations via Demonstration Hey HN,<p>We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode.<p>The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code.<p>How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructure<p>Closest analog is Playwright codegen but: - Infrastructure is handled (remote browsers, proxies, auth state) - Code runs in a deployable runtime with logs, retries, and optional agent fallback<p>Agents are great for prototyping and dynamic steps, but for production we usually want versioned code and predictable cost&#x2F;behavior. Happy to dive into implementation details in the comments.<p>Demo: <a href="https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;f83cb83ecd5e48188dd9741724cde49a" rel="nofollow">https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;f83cb83ecd5e48188dd9741724cde49a</a><p>-- Andrea &amp; Lucas, Notte Founders
