Show HN: Yet another daily word game – wotd Howdy HN. I wanted an excuse to do some lightweight JS/TS development and to get reacquainted with the Cloudflare stack, so I put together a daily word game. It's partially inspired by NYT's Spelling Bee and Wordle. The main goal is to find a specific word each day that uses each provided letter at least once. There's a secondary goal of finding as many words as possible. Right now progress is all stored on-device, but in the future I might add leaderboards or other competitive elements. …

Show HN: Testronaut – AI-powered mission-based browser testing Hi HN, I’ve been working on a project called *Testronaut*, an autonomous testing framework that combines AI reasoning with real browser automation.

Show HN: I made a safe anonymous message app Subrosa is an anonymous message-sharing platform where anyone can visit your unique link and write whatever’s on their mind: secret confessions, honest thoughts, or wild opinions, completely anonymously. You get to read what people say about you on your personal dashboard. What sets this apart is the AI-powered moderation that filters out hate speech, abuse, and spam before it ever reaches you, creating a safe space for honesty without toxicity. This is an alpha release with a basic UI as we focus o…
Show HN: Tiered storage and fast SQL for InfluxDB 1.x/2.x https://ift.tt/yvmGL05
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 bounda…
Show HN: I made FiscalBud to send invoices fast and worldwide in 77 languages https://ift.tt/WY3AaLg
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 m…
Show HN: Trayce – “Burp Suite for developers” https://ift.tt/TufNsI6
Show HN: Trayce – “Burp Suite for developers” About a year ago I introduced Trayce to HN as the "network tab for docker containers". Now I have released a new version which adds an HTTP client. The idea is to combine network monitoring with an HTTP client to help developers interact with and debug web application servers. Think "Burp Suite for developers". Trayce stores requests as local files using the .bru file format. The UI is based on Flutter which means it offers a super-fast and modern desktop GUI with a total downlo…

Show HN: I built a simple tool to automate data into Google Sheets and BigQury https://ift.tt/u4EKyxo
Show HN: I built a simple tool to automate data into Google Sheets and BigQury I’ve been a freelance data analyst/developer for a while and I’d regularly get hired to build custom data pipelines and dashboards in Google Sheets/Looker Studio. Custom data integrations came with a large upfront cost, and possible maintenance but clients told me they were reluctant to use the major data connector platforms as they were complicated and expensive over time, so I decide to fix this. I recently built SyncRange to be dead simple data connector to Googl…
Show HN: From Hacking a T480 to the Fastest Open-Hardware 75 Hz E-Ink Display https://ift.tt/7ajY0Ze
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/xpl2GMa 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 co…
Show HN: I Built Economic Safety Mechanisms for AI https://ift.tt/UqLO1mT
Show HN: I Built Economic Safety Mechanisms for AI Title: I Built Economic Safety Mechanisms for AI - Seeking Feedback I have implemented the Reputation Circulation Standard (RCS), which uses exponential decay (like radioactive decay) to make harmful AI behavior economically irrational. The key insight: instead of trying to control AI, create environments where beneficial behavior is the only stable strategy. Power accumulation becomes mathematically impossible. Technical details: - Smart contracts for reputation circulation - Consensus algori…

Show HN: Using DSPy to enrich a dataset of the Nobel laureate network https://ift.tt/XWJdAq2
Show HN: Using DSPy to enrich a dataset of the Nobel laureate network I've been working a fair bit with DSPy lately, and I did some work in combining the benefits of vector search and LLMs (via a DSPy pipeline) to disambiguate records with a high degree of accuracy to help enrich a dataset. The blog post shows how this approach scales well, is very cost-effective and super concise - all it takes is < 100 lines of DSPy code and it all runs async. The code to reproduce is in this repo if anyone's interested (all tools are 100% free an…
Show HN: I built the fastest VIN decoder https://ift.tt/z6Yxgsb
Show HN: I built the fastest VIN decoder Decodes any VIN in ~20ms with zero network calls. I compressed the entire NHTSA vehicle database into a 21MB SQLite file that runs completely offline. No API keys, no rate limits, no servers. Just download once and decode forever. Works in browsers, Node.js, Cloudflare Workers - anywhere SQLite runs. Would love any feedback and to answer any questions about the implementation. https://ift.tt/ApKonrD August 5, 2025 at 02:42AM

Show HN: I made a competitive debating game(like chess.com but for debating) Got tired of my debates with my friend's ending in "I'm right bc I said so" so I made a platform where you can debate with your friend's(or a bot, recently added feature) about whatever you want, and after the debate is done a LLM judges who's more sound in logic. Gain points and climb the leaderboard! Feedback and criticism would be appreciated(there's a discord in there if u wanna talk more in depth) https://ift.tt/LvoBpQx August 5, 202…

Show HN: AI Physics Tutor with Free Body Diagrams https://ift.tt/LyRA0z4
Show HN: AI Physics Tutor with Free Body Diagrams Hi HN. I built a prototype AI physics tutor that can interpret, draw, and edit free body diagrams. Lately I've been transfixed with generating diagrams with LLMs. If you pipe generated JSON through a D3.js renderer, you can get pretty consistent SVG results with the smarter models. This physics tutor prototype is an example of an application. For a couple premade scenes, you can ask it to make an FBD, decompose an angled force into components, run through the math of Newton's Second Law…

Show HN: Fast Elevation API with memory mapped tiles https://ift.tt/nYkT9xe
Show HN: Fast Elevation API with memory mapped tiles I recently wrote and launched a high-performance Elevation API, built from the ground up, in C. I was highly inspired by the handmade community and I was intrigued by the idea of handling fairly large datasets and optimizing caching and smart prefetching, and to cream out maximum performance in terms of latency and handling large loads. The whole thing is built from scratch. I wanted to roll my own high performance server that could handle a lot, mostly for the technical challenge but also b…
