Show HN: An eBPF kernel guard for vTPM access A kernel guard I prototyped after eBPF and vTPM work for a customer, where we use the TPM to protect the private keys for mTLS. Any process running as root can open the TPM devices, and so can any process in the `tss` group, through `/dev/tpmrm0`. That means they can use those keys too. This is a prototype and some research into protecting this path. https://bit.ly/4hLfDZa October 4, 2026 at 10:34PM

Show HN: Television – an open source GUI for your agent harness https://bit.ly/4AIjD5n

Show HN: Television – an open source GUI for your agent harness Hi HN, I'm co-creator of Television ( https://bit.ly/3Vq2kpu ). Me and the team at Telepath ( https://bit.ly/4ytledD ) have been cooking on this and testing it with a few hundred alpha users. We just opened up the repo to the public today. Television is a clean, beautiful place for all your artifacts. Think of it as a GUI for your agent harness, a visual space for creating and working with artifacts in collaboration with your agent. It works with any agent harness (Claude Code, Codex, Hermes, OpenClaw, Pi, OpenCode, etc) and uses whatever inference provider(s) your agent is already using. It's open source. A CLI and lightweight server get installed wherever your agent harness is running (Linux or macOS for now). These talk to our macOS client app, which can be running anywhere (the browser is also supported with a few limitations). A set of skills tell your agent how to put artifacts on your TV's screen and modify them over time. You use the client app as a sidecar -- i.e. you chat with your agent the way you normally do, but it can now respond by creating artifacts and putting them on your TV. Everything that ends up on your TV is yours and can be modified by talking to your agent. The entire UI, and your artifacts, are themeable. We noticed lots of people are using artifacts in agents like Claude Code/Cowork and Codex, and lots of developers are spinning up little websites and webapps for working on projects, organizing their life or work, etc. But it all either ends up locked inside your agent's interface or as a mess of random tabs running on a bunch of ports you quickly lose track of. We think that the future of personal computer interfaces isn't just chat, any more than it's MS-DOS. Artifacts are an early first step beyond chat. We think they should be easier to work with, and that you should own your own artifacts. So we made Television. It's early but give it a try and let us know what you think: https://bit.ly/4yuN1dC (BTW: we're building TV via an end-to-end fully spec-driven dev process, with custom tooling that also pulls in design and UI work. Planning to share more about that in the near future.) https://bit.ly/3Vq2kpu October 3, 2026 at 12:25AM

Show HN: PhreshOS – OS for Web Apps https://bit.ly/46SAsNl

Show HN: PhreshOS – OS for Web Apps I'd like to share my experience building this system with you. It's an operating system for web applications, and it took me about six months to develop this model. The idea is that every time I build a web tool, I need to design the infrastructure, including authentication and communication. If it's a WebSocket, it's even more complicated; I need another port for each application. I couldn't find any neutral tool that provided all of this ready-made, allowing me to build my tools directly on top of it. This is where the PhreshOS project began. It's an open-source, neutral platform for any web application, with everything ready-made: authentication, two-way communication without any configuration, and more. Another key feature is that the applications run as Node.js threads, instead of each application using its own Node.js. This means that on a simple server, dozens of applications can run without any problems, unlike if each application had its own Node.js. Furthermore, AI agents can use the services of these applications and interact with the same state displayed by your application's interface, without needing a separate interface of their own. The project and all its associated packages are open source under the MIT license. I welcome all your feedback, both encouraging and critical. https://bit.ly/4yrbNeB October 1, 2026 at 11:55PM

Show HN: Smartly – Plain English to shell commands, with GNU/BSD awareness https://bit.ly/4e5psQo

Show HN: Smartly – Plain English to shell commands, with GNU/BSD awareness I built Smartly because I kept knowing what I wanted to do in the terminal—but forgetting the exact syntax and flags. Smartly turns plain English into shell commands, using your OS, current directory, and Git context to help produce something relevant to where you’re working. It saves the back-and-forth of copying commands from an LLM into your terminal. It also supports Claude Code and Codex CLI if you already use those with a subscription. There’s also a --learn mode for when you want to understand the command, not just get it done. I’d love feedback. Thanks! https://bit.ly/4z3boyV October 1, 2026 at 02:54AM

Show HN: Yantra – an LALR(1) parser generator for C++ https://bit.ly/47pmtP8

Show HN: Yantra – an LALR(1) parser generator for C++ Yantra is a C++ parser generator: lexer, parser, and AST walker all generated from one tool. It builds the whole AST first, then walks it. Most LALR parser generators (Yacc, Bison, Lemon) run your semantic actions during parsing, as each rule reduces, bottom-up. That means at the time a rule's action runs, you don't yet know what its parent looks like. This pushes a lot of grammars toward hand-built AST classes and a separate walking pass whenever you need to look ahead into siblings or defer a decision until more context is available. On the other hand, Yantra always builds the whole AST first, then walks it top-down in a separate pass, calling your semantic actions as it goes. A parent rule's action can run before its children are visited. A single grammar can define more than one walker. For example, one that emits C++, another that emits Java, from the same parse. The AST and the walker classes are both generated for you. A small example (full version, with compile commands, in the README): start := expr; expr := expr(a) PLUS expr(b) %{ std::cout << "Adding" << std::endl; %} expr := NUMBER(N) %{ std::cout << "Number: " << N.text << std::endl; %} NUMBER := "\d+"; PLUS := "\+"; WS := "\s+"!; Running this on "1 + 2 + 3" prints: Adding Number: 1 Adding Number: 2 Number: 3 The outer "Adding", the root of the tree, prints first, before either of its children. That's only possible because the whole tree exists before any action runs. Some other things about it: integrated lexer with mode support (for things like nested comments), an optional amalgamated single-file output mode with a generated main(), C++23, MIT licensed. It's young (0.5.1, pre-1.0) and single-maintainer, so treat it as early. I'd rather know what breaks than have it look more finished than it is. Known gaps are listed at https://github.com/TantrixAuto/yantra/blob/main/docs/known_l... Repo: https://github.com/TantrixAuto/yantra Feedback and questions are all welcome. I'll be around. https://github.com/TantrixAuto/yantra October 1, 2026 at 03:30AM

Show HN: Kanmaps – Product roadmaps like videogame skill trees https://bit.ly/4yuBjji

Show HN: Kanmaps – Product roadmaps like videogame skill trees Hi HN! I've made it possible for you to make product roadmaps like you'd make an RPG skill tree, or a tech tree in a video game. Ever since seeing WoW talent trees* in high school i've been obsessed with RPG skill trees as a way to represent information as I've thought they convey 1) Ordering, 2) Progression and 3) Contingent Requirements really well. Not only do they help give better visual structure of whats happening and what will happen - they also give people a feeling of movement, progression and hope (whereas kanban boards and issue trackers give people the feeling of dread). This isn't surprising as video games were really designed to make people excited to play on and reach the next milestone. Turns out this format is really fun for people and agents to think about their products! As an experiment I also hooked up an MCP to one of my product roadmaps and it was able to map out my current codebase to a kanmap, and then suggest realistic next ideas to make. I've even got an agent now working on the next node of a kanmap. * Kanmaps was inspired not just by WOW talent trees, but also by the Age of Empires Tech Trees, and FFX ability spheres setup. Also huge shoutout to a bank in Australia called Up who did something called the Tree of Up as a product roadmap like a video game for their banking product - their work definitely inspired things in Kanmaps too. https://bit.ly/4rGYZhS October 1, 2026 at 02:21AM

Show HN: Ledge.sh – Runnable Markdown Notes https://bit.ly/4xT6sMk

Show HN: Ledge.sh – Runnable Markdown Notes Hi HN, Ledge is a Markdown notebook that runs shell commands, code, SQL, etc from inside your own notes. I built Ledge because I spend much of my day copy/pasting commands from my notes into the terminal. I was inspired by how much cmux helped me organize my terminals - but there was still a split brain between my notes and frequently run commands. I've been daily-driving it for the past few weeks and use it for deploys, API calls, smoke tests, etc. Ledge runs your real shell just like a terminal app and can be hosted locally or remotely over SSH using ledge-server. I've been building it since July and have recently added support for all the major platforms: Mac (Silicon), Windows (WSL required), Linux, iOS, Android. Mobile devices require SSH access to a ledge-server and Android is still in beta and looking for beta testers (see link on website)! It's built on Bun and Electrobun and is free and open-source. Feel free to review the code and contribute at https://bit.ly/46R5vZO Feedback is very much welcome. Any must-have features that are missing? https://bit.ly/3Vb5cGL September 30, 2026 at 12:41AM

Show HN: Fusor – Like Vue, but the logic is Rust I've been building Fusor. It's a reactive web framework for Rust where the templates are plain HTML files, so there's no markup living inside Rust macros like view! or rsx!.

Show HN: Ppgrid – Rasterising points in minutes, not hours https://bit.ly/4d8yBaz

Show HN: Ppgrid – Rasterising points in minutes, not hours Hi all, I wanted to share a recent library I made for myself since I continually have to work with large-scale point data spanning millions of rows. I generally found existing IDW tools are insanely slow and unreliable with the datasets I commonly work with. ppgrid is an open source GIS tool and it is intended to create beautiful visualisations that don't take an absurd amount of time to process. It uses a modified Inverse Distance Weighting (IDW) approach: instead of having to traverse every single point for every single grid O(N*M), it precalculates which points intersect which grids. This means that we essentially avoid the multiplicative scaling costs associated with traditional IDW. For perspective, ppgrid is significantly faster than IDW from the likes of gdal_grid or GRASS, in the order of 17x faster. I say in the order of as I couldn't really effectively test IDW on the crappy laptop I use beyond 1M points, where as ppgrid happily chewed through 16mil points. My goals/intention for this post is twofold: - looking to share it as a tool for anyone who may find it relevant or useful - looking to stress-test it with different types of point data and try to surface any quirks, bugs or random edge case failures Important note which I discuss more in my write-up: ppgrid is not yet stress-tested or validated in terms of statistical correctness, as my current use case prioritises visualisation. AI Disclosure & Creds: I've been pair-coding this with my local Qwen3.8 27B agent, I discuss this in my write-up further. I have ~9YoE in GIS work and ~10YoE as a fullstack. GitHub Repo: https://bit.ly/4d9jDBc Any other feedback/comments are welcome, please let me know if this has helped as I'd love to see it in action. https://bit.ly/3V9wfSN September 27, 2026 at 08:22AM

Show HN: TiddlyInstall – Single HTML file that makes cross-platform installers https://bit.ly/4rus7J9

Show HN: TiddlyInstall – Single HTML file that makes cross-platform installers Hello HN, I wanted to show you some new software I designed (and Claude implemented.) It's called TiddlyInstall. TiddlyInstall is a single-page website that lets you easily build installers for all your projects. What makes TiddlyInstall unusual is there is no software to download and everything is able to work offline. Based on the project that it's inspired by: you can download TiddlyInstall as a HTML file and use it to make working binaries for Windows, Linux, and Mac. How it works: Most installers / binaries are custom per project. But with very few modifications they can be made general-purpose. Installers can be made to follow meta-data which can be vouched for by hashes in their file names, embedded data, and signatures. That means new binaries only need meta-data to be changed which can be done entirely in the browser. For the installers themselves NSIS was chosen for its amazing Windows support. Otherwise, the rest is shell scripting. I am very excited about it and would love people to try it out. All the code is open source under MIT. Feel free to report issues on the Github at https://bit.ly/4yXkCge Credits: Claude (and the authors whose works it was trained on :/) deserve huge credits for the implementation. It would have taken me months to code this all this. This project is not affiliated with TiddlyWiki -- though I am heavily inspired by that project! If anyone thinks my work is cool -- I'm currently looking for new opportunities. Feel free to reach out if there's a match (matthew@roberts.pm.) https://bit.ly/4yXkD3M September 25, 2026 at 08:25AM

Show HN: WebGCM – a global climate model running in the browser on WebGPU https://bit.ly/3VJofYE

Show HN: WebGCM – a global climate model running in the browser on WebGPU I started this four and a half years ago. I wanted to build a climate model as both a toy and educational tool that I could visualize in a web browser. I have always been interested in meteorology and asked r/ClimateScience for advice on the math and physics on building an in-browser climate model as an educational tool, and a few people said it was far too ambitious. They were right. I could build the geometry, an icosahedral hexagonal grid on a globe, and I have an intuitive understanding of the math but integrating the Navier-Stokes equations and the physics proved to be too difficult for me, and the closest I got after nearly of month of work was a model that blew up within two simulated days. Fast forward 4 and a half years. I figured that if models like Claude and GPT Astra could solve a milennium prize problem about fluid dynamics then they could help me fix the broken model and iterate on it until my vision was realized. On Friday, I threw down $200 for a Claude Max subscription, and this is the result of a single weekend's work on top of where I had left off. What it is now, in technical terms: a hydrostatic primitive-equation atmosphere on that hex grid (the TRiSK scheme MPAS uses), 27 levels, about 41,000 cells at 110 km, with grey radiation, moist convection, a boundary layer, sea ice, a land surface with snow, a two-layer ocean and real topography. Every kernel runs on the GPU; on my MacBook Pro (M1 Max) it does about 70 simulated hours a minute from a six-year spin-up, hence the 50 MB first load. You can color the globe by twenty-odd fields, animate wind or currents, draw isobars, or view it from space under the model's own sun. The URL captures the view, so links open specific places. Caveats: an educational model, not a validated one. It runs about four degrees colder than Earth and I'm still tuning it, the ocean is crude and shallow, and it needs WebGPU (Chrome, Edge, Safari 26) for best performance. It's currently tuned for my specific machine specs but I suspect it will run well on most desktop-class Apple Silicon machines from the past 5 years. Source and design notes: https://bit.ly/4hi7evN Edit: If it runs really well on your machine, something well above 100 simulated hours per minute (displayed on the top-left of the page), let me know your machine specs! You should also try to reload the page with `?N=128` in the query params and it will re-grid to an even higher resolution. But it will take a few simulated days to settle down after the initial shock from the changed resolution. If you end up tyring this, check out the Temperature overlay at 10 hPa height and you should see Gravity Waves [1] rippling through the top of the atmosphere!

Show HN: Lightspeed, bidirectional WebSockets for Laravel (with asteroids demo) Hi HN! Laravel has worked with websockets for years but generally speaking it's a one way push architecture (i.e. http in, sockets out). Lightspeed is kind of like node in that it's a single server that serves your http and your websockets all under one roof. Auth runs in 0.03ms (a Redis read, no database). Your Laravel handler runs inside the full container and the reply comes back down the same socket. I think this could be really cool for creating new ways of working with Laravel. Anyway, I put together a live demo to show it in action. Basically a cross between slither.io and Asteroids.

Show HN: Seal – Letters and passwords that open for your family after you die https://bit.ly/4hcXXFp

Show HN: Seal – Letters and passwords that open for your family after you die I'm a CS undergrad who has developed an interest in hardware keys ever since I used them for a school project a few years ago. I made a little chat app that only allows users to chat if they registered a key, nothing else. The backstory of how I came to work on Seal (this project): was that I was generating ideas with Claude to come up with an idea that only hardware keys could make into software. I was thinking about physical house keys and what you could do with those, but in software. I was already making iOS apps with Claude, and I came up with this idea and it sounded good. I had already worked on a few projects involving hardware keys and I already loved them. Today I submitted my latest app, Seal, for review in the app store. Seal is an iOS app for iPhone and iPad that lets you write an Envelope (an encrypted bundle of passwords, photos, voice memos, etc...) for all of your loved ones when you're gone. You can register hardware keys and assign identities for each person. Then you can create Envelopes and assign them to the key that you want to distribute. They plug in the key to their phone and are ready to receive an Envelope from you. If you don't log into the app for months, one of your designated key holders can start the process of opening the Sealed Envelope. You, as the writer of the letters, get weeks of warnings to check in at least once before the letters open. After 90 days of countdown, 21 days of warnings, and 14 days of grace, the envelope opens for each person they met IRL and exchange keys with. No one else can read the envelope or see the photos (even the key holders, Apple, or me) unless that envelope was designated for that person. What's different from a password manager like 1Password: emergency access there hands one person your whole vault through the company's server, so it needs that company to still exist and be honest on the day it matters. Seal gives each person their own envelope nobody else can open, and there's no company in the middle. There's also no server at all besides a free Cloudflare static site. The encrypted bundles of passwords and photos are in Cloud Kit. Sign-in/identity is a passkey Face ID/Touch ID or a Hardware Key. It's all Crypto Kit, so there's no dependencies required. Currently, it's just me and Claude working on this. It hasn't been independently audited by anyone, and it's iPhone only for now. Please do not put a live seed phrase in it yet. If anyone has advice for me as the lead developer for this project, I'm all ears! You can help contribute on the github source code repository page if you'd like. My mom likes this app especially because she's into crypto and she needed a way to pass down or give away the seed phrases for her wallets to all 3 kids without any question about who gets what and when. In the end, there's no confusion or hurt feelings after the fact with just crypto. Thank you for reading and let me know if you have any questions or concerns for me or the project!

Show HN: Cactus Needle 3: 8-29MB automation models can match DeepSeek V4 Flash https://bit.ly/4yIMoNl

Show HN: Cactus Needle 3: 8-29MB automation models can match DeepSeek V4 Flash Hey HN, Henry from Cactus here. We submitted Needle 2 here a few weeks ago, and the feedback in the discussion thread was incredibly valuable, thanks! Thanks to all that feedback, we’ve been able to move quickly to release Needle 3 and I'd love to hear what you think again. The key features: 1) Automation (tool calls & structured JSON output): Needle still doesn't chat by design, its quite challenging to pack general capacity into such small models, so we focus on tool calls and structured JSON. If no tool you declared fits the request, you get an empty list back (note for when playing with the demo). 2) Intelligence Laddering: Every layer (2 to 20) is a deployable subnetwork, so one set of weights, 25 to 121 million parameters at 2-bit, shipping as 8-29MB binaries. On a Raspberry Pi 5 it decodes at up to 4k tokens/sec and prefills at up to 10k. 3) Monarch Hadamard MLP: replaces the dense FFN with three learnable Walsh-Hadamard-initialized Kronecker (Monarch) factor pairs interleaved with per-channel diagonal scales, fixed permutations, a SiLU nonlinearity, and a rank-8 input-conditioned gate, so each token gets a fully mixed nonlinear transform of its d_model channels at O(d√d) parameters and compute instead of the O(d²) a dense 4x-expansion MLP would cost. 4) Performance: On Mobile Actions (phone commands, scored on the exact call) the 20-layer model gets 86.0 through the shipped 2-bit binary; LFM2.5 1.2B is at 82.4, Qwen3.5 0.8B at 76.0, Apple's on-device model at 57.6, all at f16. More results on the link, we do not win everywhere ofc. 5) Multilingual: Needle 3 now supports English, French, Spanish, German, Dutch, Italian, Polish, with more languages coming. 6) Finetuning: You can achieve DeepSeek v4 Flash grade performance on a narrow task with just 4L, stress on "narrow task", we found that production users often prefer tuning before production. 7) Triggers: Grounding is a common challenge for tool call, at least for Needle 2, so we added support case-insensitive regular expressions matched against each request to gate false negatives. 8) Confidence: Every response also carries a calibrated confidence score, the minimum of a judgement on the finished call and its decode probability. Act above your threshold, show the call and ask below it, or escalate to a bigger model. 9) Supported Platforms: macOS, Linux on x86-64, ARM64, ARMv7, RISC-V and MIPS32, Windows x64 and ARM, Android, iOS, watchOS, tvOS, the browser as WebAssembly, and a WASI component. Thanks for reading and as always, thoughts appreciated! https://bit.ly/4yIMpAT September 18, 2026 at 01:11AM

Show HN: A chess analyzer that runs in the browser https://bit.ly/4rdljzt

Show HN: A chess analyzer that runs in the browser I play chess casually and usually struggle to figure out why Lichess analysis say my move is a blunder. Almost all the analysis tools will just suggest the best variant for a position, and you will have to follow the suggested engine lines, or play them out manually to analyze it better. So I built this tool to make that process easier for beginner players. Behind the scene: This app run Stockfish in your browser, at a position, the app will follow the engine's suggested lines, search for any meaningful situation like a check, a fork, a capture, material change, positional disadvantages,... and point that out with an explanation. You can see the app here: https://bit.ly/4rc2H2R and paste the PGN of your game. If you play on Lichess, you can also replace the lichess.org part in the browser URl with https://bit.ly/4rc2H2R to quickly analyze, for example: https://bit.ly/4rbI8U2 https://bit.ly/4xwAXqV September 16, 2026 at 01:28AM

Show HN: Agenttik – work on multiple projects in parallel with AI agents https://bit.ly/471VQ2s

Show HN: Agenttik – work on multiple projects in parallel with AI agents Hi! I've been reading HN daily for almost 16 years. Really glad this community exist. This is my first Show HN, so I hope you find this tool useful/interesting. During my summer holidays I started playing with latest AI models on personal projects. At one point I started working in parallel with the same project and tried different approaches. The one that worked best for me was to clone the repo and distribute work among different AI workers, work in parallel but with different branches & folders. This allowed me to review and merge work afterwards. The thing is, spawning several agents in parallel was challenging. I could work on multiple features and bugfix at once, but it was hard to keep track what I was working on. I was jumping from one thing to another, and back; from one window to another. Switching tasks like this was mentally exhausting. Holidays were over, and after returning to my day to day work, I continued working using a similar approach not on one, but also on multiple projects, but I still could not find how to work in a more organized way without the mental toll. This space is growing really fast, and I haven't been able to find the right tool for myself, so I decided to build my own. I wanted a tool that would help me manage multiple projects at once, work with multiple agents, even from different providers, where I could chose between my personal and work subscriptions depending on the project, where I could easily review changes without leaving the tool if I wanted, or go all in and delegate fully to agents; one where I had quick shortcuts to move around, where I could schedule work or enqueue work for later so agents could work on one task after another. agenttik is my way of tackling this problem to work on multiple projects in parallel, while allowing myself to be on the driver seat. I can give as much autonomy as I want to the agents while keeping things organized in my head. I've been hesitating for hours on whether to submit or not, but hey "if you are not ashamed of your project, you are shipping too late" Honestly, this project has exactly one week of development, started from scratch, and even though it is still early on, it has been extremely useful for me. I've built in a week things that would have taken me months, not only built the tool itself but other projects as well (most of the merit is still on the models used, but would have had no way of distributing all the work, though). Feel free to try. Here's how I would get started: - Open a project you already have - Add some general prompt (in the project area) or add to your AGENTS.md/CLAUDE.md (to instruct it to do regular commits and/or work with branches, and also instructions on how to build effective tests so that it can self-correct). - Chose your subscriptin of choice: Claude Code / Open AI subscription / ... - Pick big models (Opus High to Max / Fable Medium to Max / Astra Medium to Max) for bigger autonomy and try not to do hand-holding Finally, start sending/enqueuing tasks on all the features you want your product to have, bugfixes, ... use a new prompt per task (Ctrl+T / Cmd+T), I recommend using big models to avoid investing your own time reviewing, and then once LLM is done, review and archive that task or continue iterating. Keep adding tasks as you think on them. Add more projects as you start feeling comfortable. It has been really addictive for me to see the speed of development when working like this. I got totally hooked. Speed of iteration is insane. Happy to discuss any feedback you have even if it is about other tools or ways of working with AI these days! I hope you like it!! https://bit.ly/3TCdua1 September 16, 2026 at 12:24AM

Show HN: Surraura – audio on your Mac in a simulated environment (Helps my ADHD) I built an app to help my late diagnosed ADHD - through sound. The app wraps whatever is playing on mac through device convolution (old radio, hifi system) - Room convolution (a bedroom, a forest) and adds ambience (rain, wind, waves) and Apples spatial processing - so it sounds like a real space. For me - hearing the sound in a space really helps more than just the dry sound, the spatial information and ambience lets me focus much more. At some point I thought- Maybe others will have the same effect? So I took the care and effort to make into a nice app with the option of downloading additional environments etc. https://bit.ly/4hq0rl5 Thank you for your time, would love to hear your thoughts.

Show HN: Don't Hit Send – the model answers while you type Type. The model is already answering. There is no send button. Left pane is one long draft. Right pane is a stack of replies. Pause for ~350ms and it fires a normal streaming chat completion with the whole draft. Type again and it aborts the last request if that reply never produced text; if it did, that bubble stays and a new one stacks. Bubbles never rewrite. Enter is a newline. That is overlapping unary streams, not a duplex socket. Same shape as ghost-text, pointed at a conversation instead of a code line. The bit that took the work is the hold: do not fire on "and N" while someone is still typing "and NASA". git clone https://bit.ly/3USgQpE cd dont-hit-send export SCALATTICE_API_KEY=slt_... # or OPENAI_API_KEY + OPENAI_BASE_URL ./run.sh # https://bit.ly/3T0aCDG Stdlib Python, MIT, key stays on your machine.

Show HN: Dbmask – Discover, mask, and verify sensitive data in SQL databases https://bit.ly/4xh0vII

Show HN: Dbmask – Discover, mask, and verify sensitive data in SQL databases Hi HN I developed *dbmask*, an open-source Python tool designed to discover sensitive columns in SQL databases, masking them with deterministic fake values, and validate the masking results. The motivation behind this tool stems from a common issue I encountered when handling test data: existing masking tools often assume the user already knows exactly which columns contain sensitive information. Furthermore, the successful completion of a masking task does not guarantee that all sensitive values have actually been replaced. dbmask aims to integrate these steps into a unified workflow rather than treating them as three separate tasks. During the detection phase, the tool makes determinations by combining column names, sampled values, database type/context, historical decisions, and optionally LLMs. While LLM functionality is disabled by default, it supports local execution via Ollama or other services compatible with the OpenAI API. If the tool cannot determine a column's nature with confidence, it marks it as `UNKNOWN` rather than simply classifying uncertain cases as "non-sensitive." I also wanted to incorporate human decision-making into the system. Detection results can be exported for manual review, and confirmed decisions can be saved in CSV, XLSX, or Markdown formats, or stored in a SQL history decision table. The system logs information about both the analyst and the reviewer and re-evaluates past decisions if column types change or review results expire. The masking process employs deterministic mapping, ensuring that identical original values consistently map to the same synthetic values across different tables. Once masking is complete, the `dbmask validate --strict` command compares the masked copy with the original data, checking row counts and table structures, and verifying sensitive values row-by-row using primary keys wherever possible. The project is currently in its early stages (version 0.1.x). The current CI (Continuous Integration) pipeline covers SQLite testing; integration tests for PostgreSQL and MySQL, as well as public detection benchmarks, are included in the future development roadmap. I would particularly appreciate feedback on the detection rules, the manual review/history tracking workflows, and the verification methods. Please let me know if you encounter any usability issues or potential security risks while testing on the temporary database. Install: pip install dbmask https://bit.ly/3Vnsmtg September 10, 2026 at 04:15PM

Show HN: VolAnti – Open-source acoustic detector for fibre-optic FPV drones https://bit.ly/4cugcVu

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 drone attacks are not run on normal wireless drones, instead they are run on small FPV drones that are connected to the operator through a long spool of fibre optic cable. This simply means that drone detection through Radio, the current industry standard, is not applicable. My solution was to build an acoustic detector. A device that uses 4 MEMS microphones to capture the drone's propellers' emitted noise as they cut through the air, runs that data through several algorithms to enhance the SNR, reduce noise (directional, possible confusers), recognises their comb looking shape when plotted by frequency, and alert the user through multiple outputs (display, beeper, buzzer, led) along with alerting all nearby units using a LoRa module also fitted in the device. The units have been tested against a custom drone rig, housing the exact same specs as the drones used in the Israel-Lebanon border (four 2807 motors, 7 in tri blades, FPV airframe), which was stationed 104.2m away from the device in a street with passer-by's and mild wind. That test ran successfully and the device was able to detect the drone. This device was built for detection and alerting only, so no jamming. Every online resource i could think of in regarding this project exists in the Github, along with a neat website that shows off more media with explanations, also housing a live detector simulation that runs in the browser: https://bit.ly/4xQf1IC https://bit.ly/4gVfWQq September 9, 2026 at 01:08AM

Show HN: Zero downtime embedding model upgrades https://bit.ly/4ctEEq2

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 determining k, I held the k constant above to give some sense of migratability). You can install it with pip pip install embedflow and the code is on github https://bit.ly/4zXvTyx https://bit.ly/4zXvTyx September 8, 2026 at 03:35AM

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 cloud sharing. If you want the networked features, the companion website lets you browse and download timers, upload your own, and share them with other people. Everything available today is free. I may eventually add optional AI-assisted timer creation as a paid feature, but I haven’t settled on the business model or pricing. I'm more doing this to solve my own problem and hope it will help others as well. I’m interested in whether the underlying abstraction makes sense: does a sequence of dependent and parallel timed steps help you? I’d also appreciate feedback on the balance I took between the completely local experience and the optional sharing layer (I was partially inspired by the old iOS Workflow App, which was acquired by Apple and is now called Shortcuts). Of course, any other feedback very much appreciated. [0]: https://apple.co/4zXnb3g... https://bit.ly/4xcAWbQ September 4, 2026 at 11:47PM

Show HN: Interactive map of the Japanese address system https://bit.ly/4xbIziG

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://bit.ly/4iLta4P September 4, 2026 at 07:42AM

Show HN: Reactor Atlas https://bit.ly/3Vc6aSN

Show HN: Reactor Atlas Hi HN, I'm a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs. Now I'm joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a dark age when I was studying after the Fukushima event) so I think this is the right moment for me to jump again into the field. Reactor atlas is an interactive nuclear reactor map and an intelligence layer on top of it. The basic layer indexes: - power reactors - research reactors - fuel facilities with their history and projection, by country. The project is solving a fragmented information ecosystem, where operational and commercial data is hard to conciliate. Also, I'm monitoring nuclear news associated with each of the facilities, political declarations that may affect the nuclear landscape and geo-phisical news (like earthquakes) that could affect operation. On top of the operational + news layer, I'm creating an intelligence layer that will help institutions of different types make faster decisions by subscribing to very specific alerts. As an engineer, I used to code in fortran and c++ when I was working at CNEA, and later I participated in the first Rather Labs projects architecting complex async systems, mostly using MERN stack. I'm no longer coding anymore. I'm focused on designing robust systems with AI agents. I mainly used Claude Fable 5.1 to develop reactoratlas.com, deploying on vercel and using mostly nextjs, threejs, postgreSQL and some cron jobs to query and update data. I miss coding as in the old days, but I haven't code a single line in this project. And I strongly believe we humans shouldn't code anymore: our responsibility is now on designing and supervising AI systems. Thanks for your attention! https://bit.ly/3US1Vf6 September 3, 2026 at 01:33PM

Show HN: I made a word building game supporting anagrams and one handed use https://bit.ly/4yk2BIL

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://apple.co/4yiPgQP... Would love to hear feedback to improve it. September 3, 2026 at 03:37PM

Show HN: Notes Plus – A Markdown Apple Notes Clone with Latex, Excalidraw etc. tldr: clone of Apple Notes, but every note is a local Markdown file. Hi, I used a summer of unemployment to actually finalize a hobby project, a literal clone of Apple's Notes, with open access to the filesystem, meaning each note is just a markdown file. Then implemented renderers for Excalidraw, Latex, AsciiMath, mermaid diagrams, PlantUML, Graphviz, Vega Lite, mhchem and footnotes (a feature i need a lot in texts). It can also show notes in vertical lists, like swimlanes, I call it "JIRA view" ;) Free for now (might monetize later if successful, with $19 one-time payment, NOT subscription)! I'm not 100% sure about the legal aspect of this, but i will try to even list it in the Appstore. The binaries are signed / notarized by Apple. *PLEASE NOTE:* This is an early alpha! SO BACKUP YOUR STUFF OR JUST WORK WITH COPIES! There are issues! I'm posting this here to collect hurtful user feedback.

Show HN: Saccade – Live semantic browser truth for AI agents https://bit.ly/3SDsfsO

Show HN: Saccade – Live semantic browser truth for AI agents I build one this application is to resolve the most of the agent cannot handle the brother they extremely slow. So I come up with this idea, we install one of the extntion on chrome or edge to give continuously compile the tabs authorized by the user into semantically meaningful objects with stable identities, and push page changes as deltas to the local Node.js Broker. 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 stuff. I want somebody to check and use it. If it is possible plz give me some feedback. https://bit.ly/4qPDIC8 September 1, 2026 at 12:35AM

If you're building browser-based apps that heavily interact with the file-system this package is a must to have in your package.json! A React hook that watches a directory and re-renders when a file is added, changed, or deleted. Point it at a folder the user picked and you're reading and writing their real files — no uploads, no endless file dialogs New in 2.0: it watches the origin private file system too. No picker, no permission prompt, no user gesture — and, unlike File System API, it works in Safari and Firefox What's OPFS? A file store the browser gives each origin — real directories and files, but readable only by your own site through the File System API, never by the user's file manager or other apps. https://bit.ly/4qCcgrr August 25, 2026 at 11:58PM

Show HN: Ecdeos – P2P Web/Native Distributed OS on Entity Core Protocol https://bit.ly/4qIzfkQ

Show HN: Ecdeos – P2P Web/Native Distributed OS on Entity Core Protocol Hello, I wanted to share an update of the current progress of the Entity System. https://bit.ly/4geUCXe is one domain in a constellation of peers/sites that is the main project of the Entity System, a Tauri Rust/WASM browser engine and Rust backend built on the Entity Core Protocol. 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", content-addressed data, full decentralization, and its capability security model gives it a unique position in the landscape, most of it coming from the Entity Core Protocol itself. Each web deployment also ships with 30+ Entity-Apps including games, music (forgive me if the audio misbehaves, it's fully synthesized running on the main thread), art and basic tools. Entity-Apps have a basic contract with the host and run in isolated iframe sandboxes; they're currently written in Javascript using a custom engine. Also included are a few Entity-Native compute apps running as Rust WASM Entity Core peers in an iframe that show the transferable Entity System compute language running live on a cross platform generic system host interface the engine manages. The compute code is compiled/tested on a separate workbench Go project which operates a parallel implementation of the application conventions, generic system host interface and the Entity Core Protocol. The Tauri native backend peer includes support for SQLite storage, TCP and WebSockets, while the browser environment supports WebSockets and WebRTC P2P chat, file and entity transfer - with plans to add more storage, networking and application conventions. Sites and a registry example are hosted at https://bit.ly/4gSgmbB . All the Ecdeos-based domains are running with peers in "coral reef" mode (no live peer required) and can pull the CDN hosted registry names and fetch the signed hosted sites from any other domain/peer in the network; they are cached locally in each peer's local storage afterwards. Peers can sign/host their data publicly on standard commodity hosting services and both the registry and sites are available to any application that understands the Entity Core Protocol and system extension standards. For the other example domains with peers hosted on static sites as well as more background information, see https://bit.ly/4gTdF9G , https://bit.ly/4d3pY0O , or https://bit.ly/4y5IVs3 . Bills Lab is the research arm that is currently exploring the background technology from different perspectives. Almost all of the code and content is AI generated, but we do our best to make it some of the best slop available on the internet. The overall project is still early and needs to get stress tested but the design is holding up well so far. Let me know if you have any feedback. -Bill https://bit.ly/4geUCXe August 25, 2026 at 10:20PM

Show HN: I wrote a BASIC interpreter that boots on UEFI machines https://bit.ly/4itDGxv

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 Microsoft BASICs rather than creating a modern language that merely happens to use BASIC syntax. I'm currently porting my text adventure Pixel Prose to Thoreau BASIC. That's becoming a much better test suite than artificial tests because every missing feature or subtly wrong behaviour eventually gets exposed by an actual program. The project is deliberately small. The UEFI version greets you with: "I make myself rich by making my wants few." — Henry David Thoreau followed, somewhat ironically on a modern PC, by something like: 27,340,685,312 bytes free I'd be interested in hearing from people who wrote BASIC in the 80s/90s, interpreter/compiler people, and anyone sufficiently strange to still find a Ready prompt inviting. https://bit.ly/4it2t4R August 23, 2026 at 06:48PM

Show HN: OzBrain, a shared brain for knowledge between agents and your team https://bit.ly/3ULYK8E

Show HN: OzBrain, a shared brain for knowledge between agents and your team I think agent-first chat interfaces will be a primary software modality and busy dashboard/UI will go away. I’m not sure who exactly wins it, but I want my knowledge to grow/go with me. A lot of the “knowledge” ie research, analysis, reasoning will be done by agents as the primary user. Our current notes tools & tasks management systems were built for humans… I don’t care what the 17th thing on my bug backlog is. I want to conduct agents that can execute for me and do great work. What I built OzBrain to do: + Create a central place for agent reasoned knowledge to live + Be agnostic about what apps/agents connect to it + Capture everything and track it so I can audit it + Enable teams, collaborators or partners to share brains + Handle conflicts so many agents in the same article doesn’t blow up + Refactor knowledge into more token friendly chunks and map the index well + Close the knowledge loop so new thinking supersedes old thinking across the corpus. Don’t erase, depreciate and link + Keep user data safe and secure ++ Be easy enough to use that you don’t have to have any technical knowledge Some among us will always build their own custom solutions, but there are millions of tech professionals and small business owners that will use agents heavily and need a solution. So I’m trying to build that. Isn’t this like gBrain? Yes, similar. I think it’s like AWS vs Vercel. AWS is very powerful, configurable, and useful if you’re technical and want to invest the time into really fine tuning your system… but if you just want your web deploy/hosting to just work and be easy to deal with you use Vercel. // WHY I MADE IT I’ve been enjoying getting back to my technical roots, as I lost my coding skills more than a decade ago, but with AI I can focus on the system and the product in partnership with agent coding workflows. I recently built a Voice AI for older people. To build it I created an agentic engineering workflow (feel free to rip that up as I’m always looking to improve systems: https://bit.ly/3UsGC3y ) My approach with coding agents is trust but verify, and I’m trying to replace the parts where a human would review with an adversarial or specialized agent who would give a better answer/review. I have workflows that will go high level task to shipped PR running in Claude cloud sessions. I use Claude Code locally and Cursor when I want a tighter loop on doing visual work like UI or layout. And Codex to either load balance usage for TokenThriffting or when I want a different llm to think thru something. It was a pain in the ass passing .md files around and keep track of which version was the most recent, so I built a hosted .md storage right in Supabase and any of my agents already have Supabase access. This let me build a solid, scalable, secure voice AI from my phone at the gym. All my agents have access to our knowledge, can write to it, update and refer to it as we build and improve the product and the systems we use. Out of 75 founder friends I asked about how they manage shared knowledge, 26 built their own custom knowledge systems… Obsidian vaults with 7k files synced through a VPS, markdown repos behind their own MCP servers, cron jobs stitching Supabase to a skills file… each a different Frankenstein they have to maintain. 32 said they felt the pain of moving static files around but didn’t have any solution for it. So I rebuilt my brain better and used it to build it. // HOW YOU CAN HELP Would love to have you try it out. The maintenance loop is still in alpha so not running it on customer data yet. If you built your own brain I’d love to hear how you did it. What criteria was most important for you in its design & function. If you are tired of shuffling .md files around I’d love to have you try out OzBrain and to give feedback, just ask your agent to put it in the shared bugs & features brain! Cheers!

Show HN: Linux and iPhone Continuity (iMessage / SMS) https://bit.ly/4wGX6mi

Show HN: Linux and iPhone Continuity (iMessage / SMS) After switching to 100% Linux a couple of years ago there was basically only one thing I missed about macOS and that was what Apple calls "Continuity". It's where you get texts, notifications, clipboard sync, file transfer (to/from) the iPhone from the Mac desktop. Especially that thing where OTP codes via text autofilled into the browser form I was waiting on. It took about 4 months of work: - reverse-engineering Apple/iOS Bluetooth behavior - MAP / OBEX - Bluetooth LE + Wi-Fi working together - iMessage through the iPhone's own cellular/iMessage stack - iOS app, Linux daemon, GTK app, Thunderbird/Firefox extension - no Mac involved But it is now something I'd love to show people.

Show HN: Mail client optimized for self-hosted email across multiple domains https://bit.ly/4qs7GvS

Show HN: Mail client optimized for self-hosted email across multiple domains As someone with a clean IP range and ADHD, I manage my inbox by splitting across a variety of accounts for a variety of domains. I’ve never really found a client that scratches all my itches, so I spent some time making one and it’s now become my daily driver. It’s optimised to be visually simple and highly configurable for things like colour, folders/subfolders, sorting and tweaking the search query function to better match what you search for often. There’s also some little nice-to-haves like a purpose-built PWA, bulk domain onboarding, MCP and dark mode. It’s fully self-hostable, open source and free of any AI bloat/VC fodder. Not trying to sell anything but rather make something un-shitified and simple to use, would love some feedback if you’ve given it a try! :~) https://bit.ly/4xdIHPw August 20, 2026 at 02:55AM

Show HN: A new way to read books, magnifying in and out https://bit.ly/4quXtyL

Show HN: A new way to read books, magnifying in and out After watching The Odyssey, I thought it would be cool to check out some scenes from the source in detail, but I don't have time to read the whole book. So I came up with a sort of zoom/microscope, that allows to see the whole book at a glance and then zoom in (by pinching) on the part I'm interested in. I can do so down to the actual source text and get the authentic feel the author intended, at the same time I better understand where am I in the text and also the character and places are clickable so I can quickly orient myself on the context. Moreover each character has relationships listed and a map of relationships can be opened from there https://bit.ly/4qthZzF https://bit.ly/4qtw1Bq August 19, 2026 at 11:21PM

Show HN: Draw.city – geography game where you circle the target population [US] https://bit.ly/4gfdV1d

Show HN: Draw.city – geography game where you circle the target population [US] The core idea is, you draw a circle on a satellite view map and it tells you the population inside + more info. The home page is a daily challenge, I've backfilled some "past challenges" so there's more than just the past couple of days to play, and there is also a free-draw mode that tells you population + some census demographic info & points-of-interest data from OpenStreetMap. In most cases, the data comes from taking the census blocks w/ centroids contained in your circle and summing their population. Demographic info is slightly more complex as it's not sourced on blocks, so we allocate population-weighted fractions of a source territory's published census values into the drawn territory. Happy to answer any questions about the data or the technical side. The game/app only covers US areas at the moment, I'd like to add international data in the future!

My partner & I got frustrated with hearing Brahm's Lullaby and Wheels On The Bus repeatedly. I also stand by that babies can enjoy adult music just as easily as they can enjoy "kids music". But most adult music is too dense/complex for babies to understand, so I created this to generate baby-friendly, slowed down versions of songs that we like to play for our baby & sing along with. Uses BS-roformer for stemming out the input audio + spotify Basic Pitch for transposing to midi.

Show HN: Classifier and browser extension to detect rule violating HN comments https://bit.ly/4ielCav

Show HN: Classifier and browser extension to detect rule violating HN comments I love HN, but lately I have been sick of reading the same dismissive criticisms over and over again. Along with political arguments that have been litigated to death, people's issues with smooth scrolling on blogs, etc. Many of these comments do not get flagged for whatever reason. So I made a service to automatically classify whether comments violate (a modified form of) the HN guidelines automatically. In addition there's a Chrome extension to collapse these comments (if they violate your score thresholds) so you don't have to read them too. You can also just watch guideline violating comments as they are posted on the home page. Here's more info on how it works: https://bit.ly/4ifpatb https://bit.ly/4zpdGtk August 17, 2026 at 05:04PM

Show HN: PageSieve, a web scraping browser extension https://bit.ly/45rF6B8

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 planned as well as some rough edges that need smoothing. I use this extension nearly everyday and I hope it can make somebody else's work easier. Take a look and let me know what you think.

Show HN: Mocktail – Free, open-source mock API server with a built-in dashboard https://bit.ly/3RQ70DN

Show HN: Mocktail – Free, open-source mock API server with a built-in dashboard Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. 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. It’s been fun coming back to something I built years ago and bringing it up to date. I’d love to hear what you think, especially anything you’d change or add. https://bit.ly/4ws1Iwg August 14, 2026 at 09:20PM

Show HN: Woxi - Open-source Mathematica / Wolfram Language reimplementation https://bit.ly/45iHz0H

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://bit.ly/45jDf1h . 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, I'd be particularly interested in feedback on compatibility and missing functionality. Contributions and bug reports are also very welcome: https://bit.ly/4m3tg7n https://bit.ly/3StnUrW August 12, 2026 at 11:06AM

(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://bit.ly/4woWdyr ) Feedback appreciated, and contributions welcome. I want to make this a really good course for me (and everyone else like me). * (OK, I had sol and kimi on it for most part) https://bit.ly/4woWdOX August 12, 2026 at 02:20AM

Show HN: Albedo – single-file listenable document database in Zig https://bit.ly/45lGaGC

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 awesome, but I genuinely didn't enjoy them. After initial tries Rust felt overbearing, so by method of exclusion I landed on the lizard lang. I've been working on it for about a year, all while learning zig, relearning working with memory and adding new features. This whole time I've been mainly comparing it to and learning so much from sqlite, and eventually, after tuning, I feel like the performance is close enough for me (at least in my very basic benchmarks on my laptop). Now it's my personal little engine I use in my mobile apps through flutter plugin, in my small backends using bun ffi \ node native modules. Would be cool if it would solve someone's else pains.

Show HN: CityEdit – Open-source map for voting on NYC street changes https://bit.ly/4bxZwvP

Show HN: CityEdit – Open-source map for voting on NYC street changes CityEdit (cityedit.org, https://bit.ly/4wf791E ) 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://bit.ly/4yZIccT... ). Read more at https://bit.ly/4wufqit... (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 tactical urbanism. ( https://bit.ly/45K5dTQ ) 2. There is selection and presentation bias inherent to how we've built this. Our aim is to be as transparent as possible about who is participating, and who is missing, rather than faking general consensus. We're also seeding maps with existing commute data to fill in gaps wherever we can (e.g. Citibike trip data on the NYC Bikes map) Critiques are welcome, especially skeptical takes on whether this type of civic feedback loop can work. But please be constructive too! https://bit.ly/4wK61Eh August 6, 2026 at 12:58AM

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://bit.ly/45GoLbJ The full benchmark here: https://bit.ly/4fHqzHw Am taking requests if there's more research you want to see!

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://bit.ly/4fNam26 August 1, 2026 at 11:30PM

Show HN: SmokeVPN – All-in-One WireGuard VPN Hub – Switch Exits in Realtime I have started developing a prototype of a WireGuard VPN hub, where I could set a custom exit to a specific device, for example, my TV box would use a VPN in Germany, while my desktop a VPN is Serbia and I could switch the exit in realtime without having to stop the VPN connections and consequently no disconnections (ssh, etc). 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 need an account, email or password and you can add up to 10 devices.
