Show HN: SlickFast Deterministic Chart/Dash Renderer, No Browser(JSON → SVG/PNG)https://slickfast.com/SlickFast started 6 months ago, and evolved in a super backwards way. I was using lowfruits to look for good SEO keywords, I wanted to make a simple free tool to rank with SEO. I found some great keywords related to graphs/charts. I did research for optimizing for SEO. Turns out edge processing / using static HTML is super fast and lightweight, great for SEO. I made freepiechartmaker.com. I was really blown away by how fast the site was loading, and how lightweight all the processing was. The site renders changes on the fly, and is much much faster than other sites in the space. I started looking into the tech, pure math rendering, and I saw a lot of openings for what this tech can do. That's how SlickFast was made.SlickFast is a JSON input > pure javascript SVG Native render core > with PNG+SVG output. No headless chrome. No library calls. deterministic output. on my local machine(m1 max) it renders 140,000 svg charts a second. PNG @ ~50/sec at retina (scale-2) and ~145/sec at scale-1Aug 5, 2026 3:01 PM

Ask HN: How do you correct spatial reasoning of LLMs?https://news.ycombinator.com/item?id=49181570I'm working on a complex multi-part 3D-printed product, and I needed some engineering input from LLMs. I use highest Gemini Pro reasoning levels, Fable, and K3 Max with everything tuned to highest.The problem I'm facing is mounting a sensor on a barbell sleeve. The sensor is a semi-hollow 100mm cylinder, 60mm diameter, with a 50mm diameter 50mm deep tube cutout for the sleeve. (It's a bit more complex than that.)I'm trying to brainstorm different clamping mechanisms, and evaluate durability and manufacturability of several designs.No matter what I try, the output of all LLMs is absolutely wild, especially if you ask to make a technical drawing. Anthropic reliably been the worst, and Gemini, surprisingly, the best.But none understand what goes where in any detail, besides spewing paragraph and paragraph of wild ideas including rotational cam clamps over a recessed ring TPU collet (apparently, a "brilliant pivot") and stuff like this.Is this the "unconquered frontier"?

Show HN: Simple algorithm and color space to generate diverse skin toneshttps://toneyalexander.github.io/inclusive-color-space/Hello HN!I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy.I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has.The methodology might be a bit shaky, but hopefully the result is as helpful for others as I have found it! There's lots of room for improvements (see the Future Work section), but I'm really happy with how it turned out.Aug 4, 2026 3:16 PM

Show HN: Guide AI coding agents on how to use libraries securelyhttps://github.com/Reware-Labs/securitycardsHi HN,TL;DR: AI Code Security Cards give coding agents library- and version-specific guidance to generate safer code.AI coding agents can generate working code, but they often lack library- and version-specific security knowledge. We've developed AI Code Security Cards, an open-source security knowledge layer, to provide that missing context.The project is related to my PhD, in which I focused on the security of LLM-generated code. During my research, I studied how code generation models behave, how they introduce security issues, and how we can guide them toward generating safer code.My research [1] and several other studies [2–4] show that at least 40% of code generated by state-of-the-art models contains one or more security issues. Similar problems also affect AI coding agents.One reason is that these models often lack sufficient library-specific security knowledge in their context. They may not know which configurations are unsafe, which validation steps are required, or what secuAug 4, 2026 2:12 PM

Show HN: Free SEO checker that finds redirect chains and www issueshttps://redirectiq.com/tools/seo-checkerHello, I wanted to share this free tool to check your page's SEO.I wanted to build something that did a few things I thought were important:1. Be fast, and give a solid technical SEO analysis without dragging it out. 2. Create a way to share links directly to a site's results, with the share OG image previewing the actual score. 3. Offer everything through an API. You can inspect the calls made on the page to see it. I haven't documented it yet, but it's available to use.The deepest checks we do right now are making sure your www and non-www setup redirects correctly, and looking across your site for any redirect chains that should be flattened. Alongside that, it covers the other basic technical SEO checks that matter for ranking — title tags, meta descriptions, headings, canonical tags, viewport, HTTPS, Open Graph tags, image alt text, structured data, and response time.Looking for feedback on what checks would be helpful to add, but want to keep it fast and lite.Aug 4, 2026 1:49 PM

Show HN: My journey into game development with AIhttps://playdowntime.com/I had a development background initially, moved out to a different field 20+ years ago, but often have a nostalgia with periodic attempts to create something. Wanted to share the last one, started 2 months ago as part of my upskilling with AI. Choice what to develop was easy - spent lots of time commuting to the office and wanted a simple game playable offline, without ads, within 5-10 minutes. I have never developed mobile games and this was an point of the experiment - how far I can reach? :)Stage 0 (full control & no trust) - I started with VS Code + Android Studio. Yes, Claude created something, however compilation and error correction was an old-style pain. Initially googled, then asked AI "check and correct the error". Then I realised that I don't need neither VS Code nor Android Studio. When I need to review a code, i can do it in project folder directly.Stage 1 (building the trust) - moved to Claude Code CLI. Jointly with Claude we defined the processes and the team structure (Aug 4, 2026 1:19 PM

Show HN: Neal – Codex writes the code, Claude reviews ithttps://github.com/navels/nealneal is a CLI I wrote while trying to use an LLM coding agent (in this case, Codex GPT-5.4) to work autonomously on a migration of our large frontend codebase. A few things came up during that project that guided the development of neal:1. Telling an agent to "keep working unless blocked" doesn't actually work over long stretches of time.2. Large projects should be broken up into smaller chunks of work.3. The coding agent should start each chunk of work with a fresh context to prevent context rot.4. The coding agent benefits from having a different agent doing adversarial reviews along the way.What I ended up with is an orchestrator that- lets you configure planner, coder, and reviewer roles. I started with Codex and Claude using their SDKs but later added OpenRouter as well as a compatibility mode for verifying that a model can handle the orchestration. Currently there are 44 compatible OpenRouter models.- runs a plan that you provide through a planner / reviewer loop which splits theAug 4, 2026 1:14 PM

Show HN: Popkorn – A CSS based alternative for Lottie animationshttps://github.com/ayarse/popkornHi all,I’ve been working on this project for a while now and wanted to share it here for feedback and contributions. You can test drive it in the playground at:https://usepopkorn.devI’ve been calling it Popkorn. The idea is to author vector animations, similar to Rive and Lottie, but in a CSS-like language, with interactivity and other modern necessities baked into the format. I’ve stayed true to CSS for the most part, sprinkling on a little custom syntax for things like interactivity.Staying close to CSS gives it good DX, and it turns out to make it very LLM-friendly too. Nearly my entire examples gallery is AI generated. Even cheap models like GLM or DSv4 Flash can one shot whole animations from scratch, no fine-tuning required. There’s a Copilot feature the Playground that will let you bring your own key, or use the MCP to test drive AI features. Do share what you make please!There’s a web player that renders on Canvas or SVG, and a React Native player using Skia. It supports nestedAug 3, 2026 4:41 PM

Show HN: Self-hosted pet diary built on Frigate and a local vision modelhttps://github.com/bolt12/pet-reportI have a cat and a dog, and I worry about them whenever I am away. My cameras ping me with a clip of the cat crossing the kitchen, which tells me almost nothing. I could sit and watch hours of recordings to work out how their day went and whether anything looks off, but that's too time consuming. What I actually wanted to know were concrete things: did they eat, did they drink, did the cat use the litter box, are they sleeping more than usual.So pet-report sits on top of Frigate, which I already run for the cameras. Twice a day it sends the new clips to a vision model (I run Qwen3.6-35B-A3B on an RTX 5090) on my own server and writes up the day, with every line linking back to the footage behind it so you can check it yourself. You can also ask it things like "did the dog drink today?" and it answers from what the cameras actually saw.I've found myself needing an app like this for a long time, and pulling contextual metadata out of an image or a video is exactly what these models are gAug 3, 2026 3:21 PM

Show HN: Christopher Nolan's Hymn to Athenahttps://jackcushman.org/writing/hymn-to-athena/Hi, HN! Did you know that Chris Nolan's casting of Tom Holland and Zendaya eerily echoes a 3000-year-old dance battle between Athena and Telemachus? I've been working on an art project that says so.If you like, it can be fun to go in blind with a strong research agent to sort out what this really is. Or there is a multi-layered CAPTCHA at the bottom that spells it out increasingly clearly.As a small spoiler: my day job is building reliable public data tools for a library. This piece draws on that background to try to make AI-native art -- fiction by and for humans who use AI agents as a source of truth. At best I hope it works as the kind of joke one Iain M.

Show HN: Open-Cowork – an open-source, model-agnostic computer-use agenthttps://github.com/coasty-ai/open-coworkHi HN,We built Open Cowork, an MIT-licensed desktop agent that can operate a computer through screenshots, mouse input, and keyboard input.We started working on this after using cowork-style computer agents for longer tasks. The interaction model was useful, but computer use burns through model calls much faster than chat: take a screenshot, decide what to do, perform an action, inspect the result, and repeat.We wanted to separate that agent loop from any one model or subscription.Open Cowork currently works with local models through Ollama and hosted models through providers including OpenAI, Anthropic, Google, xAI, Mistral, and OpenRouter. You can watch the agent’s actions as they happen and interrupt it during a run.The basic loop is:Capture the current screen Send the screenshot and task state to the model Parse the proposed action Execute the mouse or keyboard action Capture the resulting state Continue until completion, interruption, or a safety conditionTwo annoyingly common faiJul 30, 2026 5:54 PM

Show HN: Data structures as containers – sample chapter from my Big O book [pdf]https://thebigobook.com/downloads/data-structures-sample-chapter.pdfI was a self taught software engineer that later went to grad school to get a masters in software engineering. What I learned along the way was that many of the intimidating subjects around algorithms and data structures were much simpler and less scary than I ever thought.My hope for this book is to try and help the self taught developers get on more equal footing with people who have a CS degree - at least the algorithms class - which I always thought was most important for interviews. Along the road, I realized Big O, logs, and algorithmic complexity weren't as confusing as I first thought. This book hopes to close the gap between self taught developers and formal CS knowledge - which often gave me imposter syndrome.The linked PDF is a complete chapter from the book about common data structures you'll encounter in javascript - and leaving out some of the data structures you may never see (like Linked Lists).Note - this is one chapter of the book that was published and is available oJul 29, 2026 9:47 PM

Show HN: MandoCode Desktop – Native Windows AI Coding Assistant on Ollama .NEThttps://github.com/DevMando/MandoCode.DesktopQuick backstory on how this version came to be: the original MandoCode is a CLI, and its UI is built with RazorConsole — Blazor components rendered into a terminal. Genuinely clever tech! I wanted tabs, though, and when I attended MS Build this year I got a good look at what WinUI apps could do and saw the potential to give the original agent some actual windows and tabs. Having up to 4 agents running in one window is pretty cool. Aside from that — tabs! I feel like everything is a chat these days, and for some reason my brain keeps screaming AGENTS, not chats, at me. I love the tabbed-browser experience a lot moreSome of the stuff I got to toy with once the plumbing worked:- Context snapshots — closing an agent archives the conversation instead of deleting it, and you can snapshot mid-conversation to get an AI-written recap you can hand to a different model or a fresh agent and have it pick up the thread. You pick the LLM from a dropdown right when you create the snapshot.- TranscriptJul 29, 2026 4:48 PM

Show HN: Vostorq – I built the anti-Slack after working at a Slack-first companyhttps://www.vostorq.com/A while back, I joined a company with a "Slack-first" communication policy. I was concerned from the beginning because Slack or Teams had never felt sufficient at the companies where I'd worked before. Some discussions happened over email, meetings played an important role, Jira was used heavily, and Google Docs or Confluence was used for documentation. That setup felt necessary, but it wasn't optimal. So the "Slack-first" approach sounded suspicious, but intriguing. I was curious what they had done with Slack to solve this multi-tool mess. In practice, though, it didn't solve it for me.Take the DevOps support channel. I was new, the infrastructure setup had some issues, and I asked question after question, feeling more and more like an idiot who constantly bothers people (potentially, every person in the channel), because sometimes it was a genuine bug, and sometimes it was simply my misunderstanding of the setup. I always got answers eventually, but they were slower and shallower thaJul 29, 2026 2:45 PM
