Show HN: I analyzed why my post got 0 votes and built this https://ift.tt/s8XQrgl

Show HN: I analyzed why my post got 0 votes and built this Maybe you've had this experience too: You build something you're proud of, post it on HN with your low-karma account, and... crickets. Zero votes, zero comments. That's what happened to me last Monday. I posted my coding tool (XaresAICoder - an open-source browser IDE) that I'd built with AI assistance. In my mind it was revolutionary. On HN? Completely ignored. Then I wondered: How many other potentially great projects suffer the same fate? What "hidden gems" are we missing because they come from low-karma accounts? So I built hn-gems (with help from Claude and my own XaresAICoder). It works in two stages: Continuous scanning: Analyzes all new HN posts from accounts with <100 karma, scoring them for technical merit, originality, and problem-solving value AI curation: Every 12 hours, an LLM deep-dives into the top 10 candidates, checking GitHub repos, documentation quality, and actual utility The result is what you see at the link - a curated list of overlooked quality posts that deserve more attention. The interesting part: I barely wrote any criteria. I just told Claude "open source good, pure commercial bad, working demos good" and let it figure out the scoring. The AI assessment varies slightly each run, which actually makes it more interesting. GitHub: https://github.com/DG1001/hn-gems Is this useful? Do you have ideas how to improve this tool if necessary? (And yes, my XaresAICoder that got 0 votes? The AI thinks it's actually pretty good. I'll take that as a win.) https://hn-gems.sensem.de/ August 11, 2025 at 01:05AM

Show HN: Bolt – A super-fast, statically-typed scripting language written in C https://ift.tt/neKrFMp

Show HN: Bolt – A super-fast, statically-typed scripting language written in C I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like the embedded scene has been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be publishing toys and examples of applications embedding Bolt over the coming few weeks, but be sure to check out the examples and the programming guide in the repo if you're interested! https://ift.tt/BLlmkyK August 10, 2025 at 11:23PM

Show HN: AI Coloring Pages Generator https://ift.tt/kJwMbx8

Show HN: AI Coloring Pages Generator Hey Ycombinator News community! I'm excited to share AI Coloring Pages Generator with you all! As a parent myself, I noticed how hard it was to find fresh, engaging coloring pages that my kids actually wanted to color. So I built this AI-powered tool that lets anyone create custom coloring pages in seconds - just describe what you want and watch the magic happen! Whether it's "unicorn princess," "summer theme," or "cute kittens," the AI generates beautiful, printable coloring pages that are perfect for kids and adults alike. The best part? It's completely free to use! I've already seen families, teachers, and even therapists using it to create personalized activities. There's something special about seeing a child's face light up when they get to color exactly what they imagined. Would love to hear what you think and what kind of coloring pages you'd create! https://ift.tt/XTcljMs August 10, 2025 at 01:04PM

Show HN: Runtime – skills-based browser automation that uses fewer tokens https://ift.tt/dyIWiq6

Show HN: Runtime – skills-based browser automation that uses fewer tokens Hi HN, I’m Bayang. I’m launching Runtime — a desktop tool that automates your existing browser using small, reusable skills instead of big, fragile prompts. Links - README: https://ift.tt/RtxBga6 - Skills guide: https://ift.tt/BA2dSr9 Why did I build it? I was using browser automation for my own work, but it got slow and expensive because it pushed huge chunks of a page to the model. I also saw agent systems like browser-use that try to stream the live DOM/processed and “guess” the next click. It looked cool, but it felt heavy and flaky. I asked a few friends what they really wanted to have a browser that does some of their jobs, like repetitive tasks. All three said: “I want to teach my browser or just explain to it how to do my tasks.” Also: “Please don’t make me switch browsers—I already have my extensions, theme, and setup.” That’s where Runtime came from: keep your browser, keep control, make automation predictable Runtime takes a task in chat (I’m open to challenging the User experience of conversing with runtime), then runs a short plan made of skills. A skill is a set of functions: it has inputs and an expected output. Examples: “search a site,” “open a result,” “extract product fields,” “click a button,” “submit a form.” Because plans use skills (not whole pages), prompts stay tiny, process stays deterministic and fast. What’s different - Uses your browser (Chrome/Edge, soon Brave). No new browser to install. - Deterministic by design. Skills are explicit and typed; runs are auditable. - Low token use. We pass compact actions, not the full DOM. And most importantly, we don’t take screenshots at all. We believe screenshots are useless if we use selectors to navigate. - Human-in-the-loop. You can watch the steps and stop/retry anytime. Who it's for? People who do research/ops on the web: pull structured info, file forms, move data between tools, or run repeatable flows without writing a full RPA script or without using any API. It’s just “runtime run at runtime” Try this first (5–10 minutes) 1. Clone the repo and follow the quickstart in the README. 2. Run a sample flow: search → open → extract fields. 3. Read `SKILLS.md`, then make one tiny skill for a site you use daily. What’s not perfect yet Sites change. Skills also change, but we will post about addressing this issue. I’d love to hear where it breaks. Feedback I’m asking for - Is the skills format clear? Being declarative, does that help? - Where does the planner over-/under-specify steps? - Which sites should we ship skills for first? Happy to answer everything in the comments, and would love a teardown. Thanks! Bayang https://ift.tt/ikHPZwt August 9, 2025 at 11:15PM
