Show HN: VolAnti – Open-source acoustic detector for fibre-optic FPV drones This project has been a month in the making, and 9 fully functional units will be sent tomorrow to an undisclosed civilian site across the Israel - Lebanon border. All of my findings are shared online to anyone on the globe who could benefit from them, or make their own units. I'm an engineering student at the University of York, originally from Israel, studying in England. I too often have been hearing about tragic cases involving civilians in war zones being chased and attacked by small FPV drones mounted with an explosive. Especially around the north of Israel, Ukraine and Russian. My intentions for this project were clear: create a device small, portable and cheap enough for civilian use, that could drastically change the outcome of a drone infiltration through early alerting. I decided to dedicate a month of my summer to go back to the university labs and to work on this as personal project. These dron...

Show HN: Zero downtime embedding model upgrades People use embedding models all the time for rag/semantic retrieval. However, when a newer, more desireable model comes out, there is an expensive (both in time and computational) cost of re-embedding every document in the database. However, I figured out an interesting way to forgo that upfront embedding cost. algo: old model/index -> retrieve top-K docs -> score those docs with the new model -> cache/materialize the new embeddings so instead of rebuilding the entire vector store upfront, the old index keeps getting retrieved from, while the new model reranks those candidates. This works surprisingly well for some model pairs, (i tested 63 source-> target migrations on h100s, on upto 1M documents). For example, on a 1M document Natural Questions dataset, native Qwen3-Embedding-8B: 0.6812 nDCG@10 Qwen3-4B -> Qwen3-8B, K=50: 0.6816 Qwen3-0.6B -> Qwen3-8B, K=50: 0.6638 MiniLM -> Qwen3-8B, K=50: 0.6486 (the hard part is ...

Show HN: Cowbull – Wordle-like game where you only get match counts CowBull is a word game where you have to find the hidden four-letter word. You make guesses and get back the count of exact letter matches (bulls) and partial matches (cows). It’s a bit like Wordle, but you are not told the exact letters which match, only the count of matching letters. Scoring is based on the number of guesses and time used. There is a single player mode and a multi-player mode (no account required). The game source code is at https://ift.tt/t6RbglE . When I was younger, we used to play this game on paper at the back of the classroom during school and college in India. During Covid, I made this online version of the game to play with my kids. https://cowbull.co/ September 6, 2026 at 01:37AM

Show HN: TimerVana a Local-first scheduler for real world routines Hi HN, I’m the creator of TimerVana. It's not just "another timer app". The engineering analogy is a lightweight task scheduler for things people do in the real world. A normal timer models one countdown. TimerVana models a small dependency graph in JSON: some steps run sequentially, others run in parallel, and everything can converge on a target finish time. You can also combine multiple timers (e.g., combine a timer with all the steps to cook a steak + a timer for roasting vegetables). I originally built it because I often set multiple timers and alarms when cooking and got tired of repeatedly juggling separate alarms to get a main dish and several sides ready together. The same model also works for workouts, study sessions, morning routines, and other repeatable processes. The iPhone app is local-first by design [0]. You can create, save, and run timers entirely on your phone without an account or clou...

Show HN: Interactive map of the Japanese address system I had a hard time understanding the Japanese address system. Parts of addresses have suffixes like fu, shi, ku, chōme, ban and gō. Which suffixes are used varies between regions in a way that seemed random to me. I couldn't find a map of the system with a modern visualization, so I made one. It also shows whether an area has a governor or a mayor. For example Tokyo's wards have mayors and Osaka's don't. You can click around or drop the pin to explore, or write an address in the search bar. https://japanmap.fyi September 4, 2026 at 07:42AM

Show HN: I made a word building game supporting anagrams and one handed use Hi everyone, Wanted to share a game I built. It's called Unscramble! and I believe it's the simplest word building game. Rules: You get a few letters on screen. You need to make one word with all the letters. Tap a letter to select. Tap again to deselect. Faster you go, better you score. If you enter anagrams of the word it's looking for, it gives you extra points. If you are stuck, you can either "Ask Friend" or get Hint. You get extra points for getting the word fast but you don't get penalized for taking too long. I believe the simplicity of the game along with big touch buttons makes it perfect for one handed use. There's 6 difficulty levels in the game, and settings for things like toggling the timer, relaxing background music, sound effects, haptic feedback, removing the background animation. If you want to try: https://ift.tt/UzkrNFT... Would love to hear feedback to impro...

The Agent reads the full truth or delta of the specified tab via MCP and executes actions using object IDs bound to document. The preliminary result shows that it is very close to the performance of Playwright in terms of token use and speed. The only problem with this one is that at the very first time, it is going to send the full truth, and after that, for any page changes, it only sends the data. So, after the first read, the continuous operation of the page reaches the millisecond reaction loop. It can also upload filled forms, downloads, and all kinds of...

It's primarily a research prototype of a P2P distributed cross-platform userspace operating system. The long-term goal is functional P2P management of devices and applications, scaling from individual use (managing personal devices, apps and servers) to multi-user organizations with internal services/application stacks all the way to internet-scale public or federated P2P networks. Its closest parallels are Plan9, Erlang/BEAM, IPFS, ATProto, Nostr, as well as many other antecedent technologies including Git, HTTP, and other internet protocols. The particular combination of features and focus on "everything is an entity", con...

Show HN: I wrote a BASIC interpreter that boots on UEFI machines I started writing Thoreau BASIC because I wanted a small, old-fashioned BASIC interpreter: line numbers, immediate mode, simple graphics, strings, arrays, the sort of environment where the computer starts with a "Ready" prompt and you can immediately make it do something. Then I wondered: why should it need an operating system? So I made it boot directly on x64 machines using UEFI. The UEFI version uses the Graphics Output Protocol for its framebuffer and gets its keyboard input directly from the firmware. There is no Windows or Linux underneath it. The machine boots into BASIC. It supports the usual BASIC machinery plus graphics primitives, 32-bit colour, floating point, file operations and other features I've been adding as I encounter programs that need them. There is now also a Windows version, which makes it considerably easier to try. One of my goals is compatibility with the style and behaviour of old...

The only issue was that I suck at editing them. No amount of YouTube could hide the fact. But here's what I don't suck at. Building new stuff. I've also marveled at so much product demo videos and never quite figured out how to make my own (or pay for a professional to make one). So I made Vidmoat, my own personal AI native editor which provides an interface AI can drive. Works for both professionals and non-professionals. I mostly use mine via Claude MCP to handle edits for me and make entirely new clips. The exciting thing is that it's not limited to the provided tools. I built a 3d plugin so allow me animate a mascot i was building in 3D. I'd appreciate and love any feedback I can get on this https://www.vidmoat.com August 23, 2026 at 10:56PM

Show HN: PageSieve, a web scraping browser extension PageSieve[1] is a browser extension for scraping data from different websites from within your browser. Currently it's Firefox only but I am open to porting it to other browsers if that's something people want. My original motivation for this started with a desire to improve the capabilities of the selectorgadget[2] bookmarklet to support extracting as well as finding selectors. The ideal use case is when some data you need is useful but you don't want to spend the effort of writing a one-off script to extract it especially nowadays when a lot of websites need an entire JavaScript environment to load correctly which complicates scraping. Using this extension means you only need to maintain the selectors for extracting the data and don't need to worry about managing dependencies. As long as the website can be opened in your browser you should be able to scrape data from it using the extension. I have a lot of features...

Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding agents can create and manage mocks directly, along with an optional built-in AI assistant using your own API key. Both are completely optional.

Show HN: Woxi - Open-source Mathematica / Wolfram Language reimplementation Woxi is an interpreter for the Wolfram Language written in Rust. It comes with Woxi Studio, a Mathematica-like GUI built with iced, but you can also use Woxi through a CLI, Jupyter kernel, Python package, npm package, or WASM module. Compared with wolframscript / Mathematica, the main differences are: - Free and open source - Very fast startup - Typically milliseconds rather than seconds for the Wolfram kernel, making Woxi practical for shell scripts, one-liners, and other short-lived processes - Embeddable - It can run in a browser via WASM or be embedded into another application as a scripting language A more detailed comparison with Mathematica is available here: https://ift.tt/uUKn5Bs . Conformance is ensured with ~26'000 unit tests and ~900 .wls script snapshot tests. The current focus is on fixing remaining edge cases, improving performance, and growing the community. If you use the Wolfram Language,...

Show HN: Kernelspace- interactive course on systems programming for LLM Serving Hi HN, *I* built kernelspace - a free and interactive course that takes a backend engineer (like me) with java/python experience to the systems level required to work on LLM serving at scale. (Mostly an attempt for me to understand what everyone's talking about lately and also an attempt at staying up to date to current tech - career wise). It has: 1. 68 Lessons across 9 tracks, with a rust-from-zero ramp. 2. 8 rust labs - BPE tokenizer, KV block manager, radix cache, batching scheduler, a toy executor 3. 9 simulators running in browser (wasm) - roofline model, KV cache pressure, continuous batching dynamics 4. Fleet week - a simulated prod serving fleet All progresss is local - there is no server (it's served from github pages, repo here https://ift.tt/9QCjeEw ) Feedback appreciated, and contributions welcome. I want to make this a really good course for me (and everyone else like me). * (OK, I ha...

Show HN: Albedo – single-file listenable document database in Zig It's literally an indexable BSON array with query listening, replication and basic crash recovery. While working on my little projects I always felt a need for some sort of simple storage, where I can just have a single file. However sqlite with its' schemas and migrations always felt icky, like an overkill to have a single file db, but a whole folder set for migrations. JSON files would require to be loaded all at once and for something small but thick, like microservices that would hold their own state this would be a startup time cost. So idea came initially as an "indexable and partially loadable json object array". From the very beginning I've wrote it in zig, unlike my other projects where I flip flop with implementation language, for the sole reason that I wanted to be able to use it in as many places as physically possible. So it was something on level of C\C++, Rust and Zig. C langs are awe...

Show HN: CityEdit – Open-source map for voting on NYC street changes CityEdit (cityedit.org, https://ift.tt/zOWQSwr ) is a map where anyone can propose street changes, e.g. safer crossings, new bike lanes, improved tree beds. Neighbors can then vote on those proposals. We just soft launched the app by hanging posters with QR codes at NYC's statistically most dangerous intersections (from open crash data at https://ift.tt/5qec7iN... ). Read more at https://ift.tt/Z7bs0UW... (A poster turns out to be a great distribution channel - it reaches exactly the people who use that street, when they are using it!) The ultimate lofty vision is to build a sensorimotor loop that can awaken a city's collective consciousness: the community perceives its desires, proposes, votes, acts. Two disclaimers: 1. A vote on a map is more of a signal than a mandate, and may be unlikely to inspire government action. Instead, for now, we are going to enact what changes we can through some cheeky tactic...

Show HN: Humor Arena – Which frontier model is funniest? What if you could measure humor? Well we've trained a model on our own dataset of ~50k human ratings to detect what jokes people find funniest. We know it's part objective, part subjective component. Subjective is out of our depth for now haha The main results: Fable 5 is funniest - beating the average model 67% of the time, with GPT 4o last at 17%. Other findings: - The models never refused to try, even with dark prompts - Thinking longer has a slight benefit - Absurdness correlates negatively with joke quality Some methodology notes: - We benchmarked our model against the human majority and it agreed 72% of the time in a blind sample test. - We had 51 US adults rate the jokes, each blind to the models, with joke order randomized, and quality checked for attention and speed. - To rate some yourself visit https://pair.laugh.so The full benchmark here: https://ift.tt/6UOWZBr Am taking requests if there's mo...

Show HN: I built a free Open Graph image designer I'm working in e-commerce for more than 15 years, and the OG images are still one of the mos neglected parts of a shop. On a few projects, even fairly simple product specific image improved the conversion from shared traffic, which is what originally led me to work on this problem. The new free tool is a browser based Open Graph image designer. You can choose a template, customize the content, add an image and download the OG image. It works without an account and manually uploaded images stay in the browser. There is also an optional checker for people who do not want to start from scratch. It can inspect your page and create an initial image proposal from its content, which you can then open and adjust in the designer. I would appreciate feedback on the templates and any customization options that feel missing and of course improvements. Thanks. https://ift.tt/ytIcwxG August 1, 2026 at 11:30PM

The project grew, and I ended up adding SOCKS5 and HTTP proxy, Tor exits, exit pools, random exits, timed exits, and exits/routes based on domains or IP addresses. I also added an in-house DNS with several default block lists (malware, gambling, social media, etc.) I found this project to have potential and decided to commercialize it, Smoke VPN was born. The logs live entirely on the RAM, and I plan to open-source the full stack as soon as I get feedback from real users, people like you... Can you please try the project for free for 7 days or 50 GB (whichever comes first)? You don't...

Show HN: Great Spectations, the Spec Checker I've worked on several projects writing and implementing specifications (particularly CLN): I've found the specs I write are much better when I quote them in the implementation, so I can see what implementers need to know. Also, when specs change in development, it's almost trivial to find where to update the code. This project is a formalization of my various hacky scripts which ensure the requirements are accurately quoted, and give coverage if any are missing. Not a major Opus, but I hope someone else finds it useful! https://ift.tt/ovqcdBa July 31, 2026 at 02:02AM

Show HN: Replicant Space – an HTTP API-based game based on the Bobiverse books During Christmas 2025, I found myself burnt out from work. The last few years had been hard, and multiple redundancies saw the company I loved reduce down to just a handful of remaining staff. As a coping mechanism, I kinda disassociated for a while - throwing myself into my personal projects. AI was destroying the passion I had for coding. I tried to find some meaning in development again. After months of throwing myself into creating this game, I slowly fell back in love with coding. I taught myself a bunch of technologies that I was previously unfamiliar - Astro, Flask, Redis, Celery, Just. Anyway, this is Replicant Space. It's free. I love building and playing it. There's a cool story. Aliens are awesome. Feel free to poke the API and take over the galaxy. https://replicant.space/ July 29, 2026 at 10:57PM

Instead of venting on your teammates and pissing them off, vent into GG Translator and it will convert your toxic message into a friendly and constructive one to share with your team. https://ift.tt/0bzxoqU My background is in building web apps with Elixir and Phoenix. I made GG Translator in early 2024 to see if I could build a desktop app in a language I had never used before (Rust) with the help of AI. It was a great exercise and I found out that I could. I used Tauri instead of Electron because it has a smaller footprint. I built the app but never released it because I wasn't ready to support it. When GPT 5.6 came out earlier this month I pointed it at the old codebase and tasked it with rewriting that entire app (still in Rust using Tauri), modernizing, refactoring, and looking for any i...

Show HN: SpinWin – A macOS menu bar app to visually rotate or spin any window SpinWin is an open source menu bar app to visually rotate any individual window. You can rotate / spin as many as you want one by one. I was scrolling reels when one came on where the content creator suggested "turning the phone upside down" for a portion. I was sitting at my mac, and decided to see if I could find something that did this. To my surprise, nothing exists, so I decided to build it. Turns out macOS doesn't provide any public API to do anything like this, so I wound up using the Accessibility API to move the target window offscreen, where it keeps rendering. Then we capture it's contents with ScreenCaptureKit, and display that on a transparent, borderless overlay window which has a CALayer to rotate it. It's written in Swift, open source, MIT license, and signed/notarized. Have fun - would love to hear your comments. https://ift.tt/PV9s5pj July 25, 2026 at 06:29PM
