Show HN: ToDiagram AI – From text to diagram, fast and easy https://ift.tt/4aNFpKs

Show HN: ToDiagram AI – From text to diagram, fast and easy I’ve been working on creating diagrams from JSON, YAML and similar formats for about three years. Over time it has grown into a general-purpose diagramming tool. With the recent addition of the MCP Server and ToDiagram Chat, I’m optimistic about where it’s headed. You can use your own OpenAI key, stored locally, without needing to sign up and generate diagrams by using natural language. https://ift.tt/RT38rjI August 12, 2025 at 01:22AM

Show HN: I analyzed why my post got 0 votes and built this https://ift.tt/iRSr7sD

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/G3euLX0

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 most embedded languages have 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/XlHxvcC August 10, 2025 at 11:23PM

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

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/QTHaKt8 August 10, 2025 at 01:04PM

Show HN: Tiered storage and fast SQL for InfluxDB 1.x/2.x https://ift.tt/LGuV2BP

Show HN: Tiered storage and fast SQL for InfluxDB 1.x/2.x If you’ve run InfluxDB at scale, you know the pain: Retention policies mean throwing away history, keeping everything means huge hardware & license costs. We built ExyData Historian to fix that. What it does? - Automatically exports old InfluxDB 1.x/2.x data to compressed Parquet in S3 or MinIO - Keep recent data hot in InfluxDB, move the rest to cheap storage - Run fast SQL on archived data via Apache Arrow + DuckDB - Query it all through one interface and / API. No hot/cold boundary for the user Why it matters - 70–80% lower storage costs - Historical queries that are as fast (or faster) than InfluxDB itself - No manual exports, no query rewrites, no downtime Who’s using it right now? InfluxDB Enterprise Customers and Huge instances of OSS, telcos and logistics companies are trying this right now. We help you to reduce your Enterprise licensing cost, cause you are going to shrink your InfluxDB cluster. You keep your existing InfluxDB running, Historian works alongside it, moving history to cheap storage while giving you more analytics power. We’d love feedback from anyone managing large InfluxDB deployments. https://ift.tt/RedlOAI August 9, 2025 at 03:48AM

Show HN: I made FiscalBud to send invoices fast and worldwide in 77 languages https://ift.tt/Gbpmeg9

Show HN: I made FiscalBud to send invoices fast and worldwide in 77 languages hi! i built an app that takes the pain out of invoicing so you can send them faster and worldwide without a headache. i've always found invoicing to be a waste of time, switching between templates, calculating taxes, tracking different currencies, and keeping files organized. so i made FiscalBud :) the idea from tools like stripe inspired me, but for invoices. it lets you create, customize, and send professional invoices to clients anywhere in the world in just minutes. it supports 8 currencies, 77 languages (you can choose the output data language and ui language separately), and works in 248 countries, so you can bill confidently on a global scale. it comes with smart templates, automatic tax/subtotal/total calculations, localized csv exports, and cloud storage to keep everything organized. (coming soon) you can automate recurring invoices, payment reminders, and follow-ups. it's built to be secure and privacy-focused, with encryption and compliance baked in. you can even send invoices directly via email using your own smtp settings, with automatically signed pdfs. i've got plenty of ideas for making it even better, like deeper automation and more integrations with other tools you already use (including Stripe which is on the roadmap). any feedback is much appreciated! :) https://ift.tt/dzgFGsm August 9, 2025 at 02:56AM

Show HN: From Hacking a T480 to the Fastest Open-Hardware 75 Hz E-Ink Display https://ift.tt/Q8FA6bM

Show HN: From Hacking a T480 to the Fastest Open-Hardware 75 Hz E-Ink Display Three years ago, I posted here about hacking together a fast e-ink laptop from a T480 because I was tired of spending all day on LCDs. I liked e-ink’s comfort, but it was too slow for day-to-day use. https://ift.tt/lw1hXFt That post drew in people, which grew into a community experimenting with ways to make e-ink usable for everyday computing. That project later turned into a company and a multi-year project to make e-ink fast and open. We built our own FPGA-based controller, Caster, and went through multiple iterations to push past e-ink’s usual limits, slow refresh, ghosting, and proprietary controllers. Now, after three years, we’ve launched the Modos Paper Developer Kit and Monitor: the fastest open-hardware e-ink display, with 75 Hz refresh and sub-100 ms latency. It works with 6" to 13.3" mono or color panels over HDMI or USB-C, supports multiple grayscale modes, and has a C API for low-level control. The hardware, firmware, and schematics are on our GitHub. https://ift.tt/rvkeFwR Our goal is to make e-ink fast and open enough that anyone can build on it, for hacking, research, or daily use. Thanks, HN, for being part of the journey. https://ift.tt/7KakLus August 8, 2025 at 06:24AM

Show HN: A light GPT-5 vs. Claude Code comparison https://ift.tt/pEqX1R3

Show HN: A light GPT-5 vs. Claude Code comparison Hi HN! Can’t believe I’ve been here over 12 years and this is my first Show HN. I guess this is two fold, One: I’m doing another startup! Charlie is an agent for TypeScript teams focusing heavily on augmentation. :) Two: Over the last week or so we put GPT-5 (through our Charlie Agent) head-to-head with Claude Code/Opus on 10 real TypeScript issues pulled from active OSS projects. Our Results GPT-5 beat Claude Code on all 10 case-by-case comparisons. Pull requests generated by GPT-5 resolved 29% more issues than o3. PR review quality rose 5% versus o3. Head-to-head case study We measured testability, description, and overall quality across 10 head-to-head PRs. Testability measures how thoroughly a code change is exercised by meaningful, behavior-focused tests. It considers whether tests are present and aligned with the diff, whether they explore edge cases and real-world scenarios, and whether they avoid vacuous, misleading, or implementation-dependent patterns common in code generated by LLMs. Description evaluates how clearly and accurately a pull request’s title and summary convey the purpose, scope, and structure of the code change. It emphasizes technical correctness, relevance to the diff, and clarity for future readers — penalizing vague, verbose, or hallucinated explanations often produced by code-generating agents. Quality assesses the substance and craftsmanship of the code change itself — judging whether it is correct, minimal, idiomatic, and free from hallucinated constructs. It emphasizes clarity, alignment with project norms, and logical integrity, while identifying agent-specific pitfalls like over-engineering, incoherent abstractions, or invented utilities. Testability: Charlie (0.69) vs Claude (0.55) Description: Charlie (0.84) vs Claude (0.90) Overall Quality: Charlie (0.84) vs Claude (0.65) Caveats Single-shot runs; no human feedback loop. Quality score uses a secondary LLM reviewer—subjective but transparent. Def looking for feedback on more evaluations we can do, also please do nit-pick the prompts, ideas, harness design etc etc. Tell us if this bar (CI + types) is the right one, or what you’d track instead. On a personal note: I’ve spent my career working on tools to help creators create, I’m extremely passionate about enabling people to do more easily. I am still somewhat uneasy about Gen AI, however I do believe the future is bright, certainly things are going to change - I would encourage you all to stay optimistic builders. Thanks for taking a look! https://ift.tt/v7CyAlg August 8, 2025 at 12:26AM

Show HN: Write lead sheets in a Markdown way and transpose in a second https://ift.tt/UGySW8H

Show HN: Write lead sheets in a Markdown way and transpose in a second Hey HN, I'm a software engineer with a passion for playing guitar. ( https://ivanhsu.co ) In the software industry, we use clever plain-text syntaxes like Markdown and Mermaid to handle complex layouts. This lets us focus on the content itself and quickly produce beautifully formatted documents. Isn't sheet music and chord charts just another form of documentation in the world of music? That's why I created Cord Land https://ift.tt/JptWL4C ! It's a website where you can quickly generate lead sheets and draw chord charts using plain text. Even better, it can automatically transpose songs! Just write in one key, and it can be instantly converted it to any of the other 11 keys you want. I've implemented a new syntax called Corduroy, an extension of ChordPro syntax specifically designed for guitarists. Besides showing chord names above lyrics, you can also customize chord charts. For example, `%x32o1o%` will automatically draw a C major chord in the first position! Feel free to try it out here: https://ift.tt/oX12nv5 For more usage details, please refer to: https://ift.tt/g9hGVLU The name "Cord Land" comes from "Cord" and "Chord" being homophones, representing chords. Let's keep our passion for playing guitar alive, even after work! Ivan Hsu https://ift.tt/JptWL4C August 3, 2025 at 08:08PM
