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: Vidmoat – My Super Fantastic AI Native Video Editor (MCP, Web) https://bit.ly/46icrid

Show HN: Vidmoat – My Super Fantastic AI Native Video Editor (MCP, Web) Hi there, I'm working on Vidmoat. A couple of months ago I wanted to venture into making videos. 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://bit.ly/3SQaera August 23, 2026 at 10:56PM

Show HN: CtrlTool – 132 free online tools for developers and everyday tasks Hey HN, I built CtrlTool because I kept needing small tools for random things and didn't want to install something or sign up for another website. It currently has 132 tools for things like JSON, JWT, Base64, URLs, text, hashes, PDFs, SEO, converters, generators, and other everyday stuff. The main thing I tried to focus on is making the tools fast and simple. For tools where it makes sense, everything runs locally in the browser so the data doesn't need to be uploaded to a server. It's still very new, so I'm mostly looking for feedback on the UX, which tools are actually useful, and what you think is missing. https://bit.ly/4gJaKAp Would appreciate any feedback. https://bit.ly/4gJaKAp August 23, 2026 at 02:44AM

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) 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.

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!

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 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

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

Show HN: Humor Arena – Which frontier model is funniest? https://bit.ly/4w5Fi3L

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://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 https://bit.ly/4hIq7dh

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.

Show HN: GG Translator – Turn gaming shit talk into friendly phrases https://bit.ly/45abJDn

Show HN: GG Translator – Turn gaming shit talk into friendly phrases Flaming teammates usually results in them cooperating even less. But sometimes you just need to let the devil out of you. 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://bit.ly/4wsxdqW 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 improvements that it could find. --- The app is a sneak peek of how an AI profanity filter might look like in the future. The ultimate integration would see it built into gaming platforms like Steam and PSN where it's not only transforming your speech on demand, but it's also able to transform incoming audio from your teammates into family friendly language so parents can feel better knowing their kids aren't being bombarded with slurs when they let them play online multiplayer games. I also imagine an incredible opportunity for voice licensing allowing users to pay to unlock voices of their favorite streamers, actors, athletes, and characters for a limited time. Who wouldn't want to sound like Samuel L. Jackson yelling about motherfucking noobs in their motherfucking lane? --- The biggest obstacle was code signing. I went through all the hurdles in 2024, paying for an expensive OV signing certificate and also paying for the Apple Developer program. For 2026 I decided that the OV signing certificate is a racket and I'm not going to pay for it again. I already have an Apple Developer account for another app so I didn't have to pay extra to sign the macOS build. For Windows, the SmartScreen warnings when installing the app are a drag, but you can just tap more info and install it anyway. https://bit.ly/4wsxdqW July 26, 2026 at 11:23PM

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://bit.ly/4wjgGFH July 25, 2026 at 06:29PM

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid https://bit.ly/4fywEVa

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid Hi, I developed Life Tile for iPhone. It tracks your time passively and visualizes it as a Mondrian-style grid. It's a one-time purchase app with a 7-day trial. I was a user of a similar app named Life Cycle. Since the app hasn't been updated in a while, I tried to make a better app with my ideas and experiences. I used a big square timeline instead of a donut chart. And I added more useful views: tree-map, map, and list. You can use categorized activities with custom colors. The data never leaves a device. No account, No Server. It only supports data backup using iCloud. It was for privacy but it also makes the development easier. I added just one anonymous usage stat with TelemetryDeck. You can turn it off anytime. There were many technical difficulties. iOS location API (CLMonitor) is not 100% precise. And many difficult cases can't be handled automatically. For example, GPS blackout inside the subway, too many venues in a small region, and a huge location like an airport. So I improved many heuristics and tried my best for easy editing. Please check the App Store for the screenshots. Then you'll know why it's inspired by Mondrian. https://apple.co/44LtV60 July 24, 2026 at 01:13AM

Show HN: An MCP server that turns async-work practices into tools More than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI. What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation? What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI): > claude mcp add open-async -- npx -y @open-and-async/mcp Transparently, yes, it's from a book I wrote which launched today, but the MCP server is open source and free to use. No purchase required. It knows the key principles of the book, and has specialized tools like `draft_decision_doc`, `convert_meeting_to_async`, `score_status_update`, `triage_sync_vs_async`. This is an experiment for me, and I'm genuinely curious if it's helpful for others. https://bit.ly/4b9bk7w July 21, 2026 at 05:06PM

Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents https://bit.ly/4wz3TPL

Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents Hey HN, I built Superserve, a compute layer that lets AI agents live inside isolated Firecracker microVMs with no session time limits. The problem I kept running into: most sandbox providers kill your agent after 24 hours. If you're running something autonomous that needs to work for days — refactoring a codebase, running tests in a loop — you're constantly fighting timeouts and rebuilding state. Superserve lets you snapshot a running VM at any point, fork it into parallel branches, and resume exactly where you left off. Each agent gets its own VM, no shared kernels. There's also a credentials broker so agents never touch raw API keys directly, and egress is locked to URLs you specify. You bring your own agent (Claude Code, Codex, etc.). We handle the durable compute underneath. TypeScript and Python SDKs, MCP support, open-source and self-hostable. Would love to hear feedback, especially from anyone building long-running agents. https://bit.ly/4vL0RXh July 21, 2026 at 11:59PM

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web https://bit.ly/4gJYoZi

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web Hi everyone, I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing our private keys, allowing them to effectively access all of our personal communications.. Many open source alternatives exist, but the problem I kept running into was not a lack of good private messengers. Signal, SimpleX, and other projects already do important work The problem was getting the people to move. A messenger is only useful when the person you need to reach is there. Asking friends, family, coworkers, or customers to abandon their existing chats is a very high barrier. Ekko takes a different approach. It runs as a browser extension on top of existing messengers. Both people still need Ekko, but they do not need to move their conversation. You can continue using the Instagram, WhatsApp, Telegram, or Messenger chat they already share. Actively building this and trying to achieve a seamless automatic encryption in the UI across all popular messengers and adding support across all browsers, IOS, android and social media.. Under the hood, Ekko uses hybrid X25519 + ML-KEM-768 and XChaCha20-Poly1305. Private keys are generated and kept on your device. You can claim an Ekko handle to make exchanging public keys easier, exchange invitations directly without an account, or self-host the public-key directory. Currently: - A Chromium browser extension, Experimental Firefox and Safari builds - Instagram, WhatsApp Web, Telegram Web, and Messenger integrations - A self-hostable key directory - Open-source client, protocol, and server code Early version Chrome Web Store: https://bit.ly/4fN1z1e... Source code: https://bit.ly/4fLTTMN Website and demo: https://bit.ly/4h7nqlt I would genuinely appreciate direct feedback especially from people familiar with applied cryptography, browser security, key verification, messenger integrations, potential solutions for iOS UI integration (faster than using browser w/ Safari extension) If you try it, please tell me what breaks or what feels confusing. Actively trying to make this better as a side project! If you discover a security issue, email kirill@useekko.app rather than posting it publicly. Looking for feedback! :) https://bit.ly/4h7nqlt July 21, 2026 at 01:39AM

Show HN: The0 – self-hosted runtime for trading bots, bring your own language https://bit.ly/4vHr1dp

Show HN: The0 – self-hosted runtime for trading bots, bring your own language So Im a solo developer who has always had an itch for algorithmic trading. Initially I started off learning how to trade algorithmically with Yves Hilpisch book "Python for Algorithmic Trading" after reading that book I was hooked and started building algorithmic trading bots. Initially these were separate python scripts that I ran on my local machine. That was a bad idea cause local machines are not reliable and I wanted to run my bots 24/7 365. In my actual career im a software engineer with experience in building distributed systems and fault tolerant web applications. I wasn't interested in deploying my code to managed services like MetaTrader, CTrader or QuantConnect etc because I wanted to have full control over my code and the environment it runs in. I also wanted to be able to run my bots in any programming language I wanted, not just Python. Sometimes I wanted to prototype a bot in Python and then rewrite it in C++ or Rust for performance reasons. Many at this point would have said why not use a framework like Lean or Freqtrade or Hummingbot. However I found that these frameworks were too opinionated and if you decide to use them then your bot is now part and parcel of their framework. I backtested my bots locally in my own specific way, and now with AI my agents can generate code, backtest and analyze the results all locally, no need to run any of it in the execution platform. I wanted bots I could deploy, version, update and monitor like any other software application. I also wanted to explore building something that creates a standardized way of running bots. This has been a 4 year journey and I made a lot of mistakes along the way. The application has seen 4 rearchitectures, 3 of which were basically complete rewrites. The first version was a python program and the bots were just modules that were loaded dynamically. The second was my serverless phase when I internally just wanted something that was online cron triggered and only works for me. The third was the first time I was dipping into kubernetes; more cloud native and the idiot in me decided to try make it a SaaS. The final form is a fully self-hosted runtime, api, cli and frontend that let you run bots as containers in a fault tolerant way both locally (through docker `the0 local`) and in a cluster (k8s) and monitor them with a minimalistic frontend. To support multiple languages there's a thin contract that the bots have to implement: a main(bot_id, config) function and a bot-config.yaml file. The runtime (written in Go) takes care of the rest, it supports C++, Rust, Python, JS/TS, C#, Scala and Haskell for those who are brave enough to try it. More on the architecture here: https://bit.ly/3TuNb57 If you want to play with the0 you can run it locally, guide here: https://bit.ly/4fbMKoV . The0 is open source and licensed under Apache-2.0: https://bit.ly/4wi6mOe I currently use the0 to run my own personal algorithmic trading bots on a single node k3s cluster on a $10/month Hetzner VPS. I have 18 bots running on 2 brokers (Alpaca, Bybit) and they have been running for months without issues. Some bots trade crypto, others stocks, some do risk analysis and others invest. Coolest bit is the API provides an MCP server so AI agents can query the state of the bots, look at their logs, monitor them and even update them. Slap an OpenClaw agent and you can effectively setup an autonomous AI quantitative trading system (good luck chasing Alpha). Now I must admit Lean has all the tools and far more quantitative prowess than the0, but I always felt it does too much. Each Lean engine runs one algorithm, and once you have lots of bots, running and managing all of them in production is left to you. That's the part the0 does, and its the only part it tries to do. If you find hiccups or have ideas for features Im all ears. More on the internals in my first comment. https://bit.ly/4wi6mOe July 20, 2026 at 02:49PM

Show HN: A self-hosted AI that turns Hacker News into a daily briefing Hi everyone, I read HN every day, but there was always more great content than I had time to read. I know there are already several HN summarizers on GitHub, and I tried some of them. They just didn't fit the workflow I wanted, so I decided to build my own. My project is a self-hosted app that automatically fetches top stories, summarizes them with AI, translates them into your preferred language, and prepares a personalized daily briefing in a nice customizable UI while you sleep. Maybe I'm not the only one who wanted this kind of workflow. I'd love to hear your thoughts, especially on what you think an ideal HN summarizer should do. https://bit.ly/4yNBeYL July 19, 2026 at 11:40PM

Show HN: Sx 2.0 – Share AI skills with your team through a Dropbox folder Hi all, author here. SX started as a CLI to let developers share skills across AI clients without having to rely on git for storage. This allowed sharing at the Repo/Team/Org and Personal level. However, the more we spoke to users the more we realized that non-technical users were actually using skills more and more but they had no way to share. And there was no way you were going to get your legal team to install and learn git. SX 2.0 is targeting non-technical teams by adding a native Mac, Windows and Linux app. Our vault format was reworked so it can be used directly as a claude or codex plugin. And by storing your vault in Dropbox, Google Drive, iCloud or others you can be up and sharing in under a minute. 2.0 also adds an extension system with extensions that manage Skill Evals, LLM de-duping, metics and much more https://bit.ly/4gUVTUf .

Show HN: ContextVault – Shared memory layer for your AI and your team https://bit.ly/4ph3IFI

Show HN: ContextVault – Shared memory layer for your AI and your team Hi HN, I'm Kevin. I built ContextVault because I kept running into the same problem with AI tools. Every project accumulated prompts, coding conventions, architectural decisions, examples, and other pieces of context that made the models significantly more useful. The problem was that this information quickly became fragmented. Some lived in ChatGPT Projects, some in Claude, some in Markdown files, some in internal documentation, and some only existed in previous conversations. Late last year, I realized several people on our team were solving the same problems independently because previous work was difficult to discover. I assumed this problem existed in other large organizations, so I started experimenting with a shared context store. I started with a local proof of concept and a rough MCP server. If I asked questions like "have we done this before?", the AI could search the database and find the most relevant item to review. If a conversation produced something worth remembering, I could say "save what we learned to the vault." After using that workflow for a few months, I found myself relying on it every day. I decided to make it available to others. I've never built a product before, and I thought it would be a valuable learning exercise to do. ContextVault is a a product for storing and organizing reusable context that can be shared across people, projects, and AI tools. Instead of copying the same instructions into every conversation, you can store them once and retrieve them through our MCP server. It is not limited to any one AI client. Your team can use ChatGPT, Codex, Claude, and Gemini and save/read from the vault all the same. It currently supports: - OAuth support for GitHub, Google, Microsoft, and GitLab - Structured context records with metadata - Multi-user organizations with role-based access - MCP server for all AI clients that support MCP - Organization-scoped storage keeps tenant data separated - Group visibility rules decide which memories each member can search - Authenticated MCP access ties every request back to a real user and workspace - Feedback signals can be captured now and used to improve ranking later - Supports desktop versions of AI clients, not just their CLI versions (mobile app support should also work) The backend is built with PostgreSQL, pgvector, Node.js, and TypeScript. The frontend uses Next.js, React, Tailwind CSS, and shadcn/ui (frontend is not my strong suit, please be kind). Authentication is handled with Clerk and billing with Stripe. I started building this for my own workflow, but after relying on it for several months I decided to make it available to others. We soft launched a few weeks ago, and I find it useful as a daily tool. Essentially, ContextVault offers a way to track memories and context, distribute them instantly to your team, and help reduce duplicated work. I'd be interested in feedback on a few things: - How are you managing reusable AI context today? - Are you relying on similar tools, or do you keep everything in Git or Markdown? - If you've built something similar, what did you learn that you would do differently? You can see the product here: https://bit.ly/4hgU2ca https://bit.ly/4hgU2ca July 14, 2026 at 12:22AM

Show HN: Hologram, photo management and culling built with Tauri https://bit.ly/4vmbWhb

Show HN: Hologram, photo management and culling built with Tauri Hello Hacker News photographers! Yes, this is essentially my take on photo colling and management, similar to the features that Lightroom and Darktable already have. Because I shoot in JPEG+RAW, my workflow looks like me going through my JPEG images and then eliminating the JPEGs I don't like afterwards in addition to their corresponding RAWs. At least on my old MacBook, the JPEGs were faster to load than the RAW photos (probably a combination of CR2, the file my EOS 40D, not having embedded JPEG previews and my buggy macOS version). Hologram would be my way of making this workflow easier to do, especially with keyboard shortcuts. I also never liked the star-based system on Lightroom or Darktable, so I implemented Pick and Reject instead (which matches what I would otherwise do with deleting photos to my system trash when I cull in the Finder app) Anyways, with my new R7 I found that bursts got more annoying to cull so I decided to create autocull on Hologram as well. This would analyze your photos and help you suggest which photos in a burst to keep, or which photos to keep in a shoot in general. Currently, this is not notarized or whatever, but let me know what you guys think. https://bit.ly/3QR13Gd July 13, 2026 at 12:10AM

Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go https://bit.ly/4yi25vA

Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go Rate limiters and circuit breakers work wonderfully well when they’re configured for the load and available capacity. But load, capacity, and latency drift over time, and keeping those settings current requires continuous effort. So I built Levee to be a hands-off, adaptive, easy to configure traffic governor. Levee is configured with a success-rate target and timeout. It then continuously monitors the workload performance characteristics to detect downstream capacity exhaustion or failures. It can also spot a surge from growing concurrency before failures arrive. It runs in-process, uses a small, fixed amount of memory, has zero dependencies, and processes millions of requests per second. In a deterministic 10-node mesh simulation, Levee outscored carefully tuned static rate limiters/breakers deployed throughout the mesh, while recording fewer failures and no node crashes. https://bit.ly/4bozc75 July 12, 2026 at 02:22AM

Show HN: Krbn, a pencil-style 3D renderer with SVG output https://bit.ly/4wCDHmP

Show HN: Krbn, a pencil-style 3D renderer with SVG output Krbn is a childhood dream I finally got to research & prototype (from a hospital bed of all places), during a medical break from my normal work: a rendering engine that draws 3D scenes the way a technical sketch artist would. It asks "which lines would an artist draw and what would they leave out?" Basically strokes are derived exactly from geometry, rather than sampling. True conics, quartics etc. So there is no shading model, it's replaced by hatching (either flat or following the curvature of the object). There's no alpha channel, the gaps between lines do the work as on paper. It introduces hand-wobble (which is seeded, so animations don't "boil" between frames) and various other things; the example gallery shows more. With all that, output is byte-stable, i.e. two successive renders will cause zero changes in Git. Full disclosure, since it matters here: this was built with significant AI assistance, deliberately, as an experiment in how far a carefully directed human-AI collaboration can get on a hard rendering problem. The briefs are in the repo - judge for yourselves. Gallery: https://bit.ly/4wtPnrK The longer story: https://bit.ly/4wtPiEs... P.S. There's no pitch here... just an invitation for a weekend skim over something I find fascinating. https://bit.ly/4wwROtF July 11, 2026 at 06:51AM

Show HN: Fortress – Give your agents unlimited access to the web https://bit.ly/4gq4tdf

Show HN: Fortress – Give your agents unlimited access to the web i personally believe that the internet is the best thing we've ever built, and arguably, nothing we made before comes close. now agents can use it too, but the web treats them as second-class. every agent works for a person, so whatever it keeps from agents it keeps from us. we believe that if we let them in, each of us gets the whole of what we built, a thousand times over. and to add to that, democratization of tools that allow this is essential, despite the fact that there will always be bad actors. so, we built fortress, which is an open-source stealth chromium engine. it is a recompiled fork that corrects the browser fingerprint from inside the engine: the surfaces bot detectors read, canvas, webgl, audio, fonts, navigator, and about thirty more, are patched in chromium's c++, with no javascript layer sitting on top for a page to catch. it beats the hardest bot detectors on the planet, works fully locally and is open source for y'all to see the patches we've made. and it comes with an mcp, so you can use it with your agents without having to do any major setup or code changes. do give it a try here! https://bit.ly/4wnq6PW July 10, 2026 at 01:57AM

Show HN: I built a free app for New Yorkers to save money on groceries https://bit.ly/3STjlqT

Show HN: I built a free app for New Yorkers to save money on groceries I built this because I see that grocery savings are achievable in NYC. People usually just go to the store they're used to going to, and it's rarely worth the effort of combing through card cashback, weekly coupons, CPG rebates. Most people leave real money on the table by not stacking them, and even more don't even know that these deals are out there.... so I built a way to automate it. You can use it for free, no login, currently NYC-only with ~690 stores. I built it so that you just search whatever you want (use commas if you want to search multiple items). Or - use the AI tool to help shop for you. If you're curious, it's powered by a trained LLama model. Honest limitations are coverage and freshness. Id love some feedback on where the data looks wrong or is stale. Question for the room - what to prioritize if you're working with messy, multi-source retail/pricing data? Is freshness or coverage the top priority if you cant get a uniform response from every source? curious on what to prioritize here. https://bit.ly/4fqTaR4 July 10, 2026 at 01:17AM

Show HN: Frugon – Find which LLM calls a cheaper model could handle (local, MIT) https://bit.ly/3SMUCo8

Show HN: Frugon – Find which LLM calls a cheaper model could handle (local, MIT) I started leaning in on AI heavily this year, as I wanted to get more done autonomously, but then my token usage climbed dramatically to the point where my weekly quota would run out before the end of the week, sometimes a couple of days into the week. I realised I had to do something about it else I'd have to double my spend. So I decided to start tracking my cost per task type. This revealed that a lot of my spend went to searches/scans or simple things like scouting tasks. I then decided to turn this into a simple CLI tool that can be used to read your OpenAI-style logs locally, and analyze the cost and compare this spend to other models, then show you how much you could potentially save by switching those calls to a cheaper model. When you run analyze you get an offline estimate priced against LiteLLM and gated by LMArena tiers. The general savings bands come from the research published by RouteLLM; but you can confirm this yourself using 2 commands --measure (shows the prompt-response output side by side) and --judge (a model chosen to do the comparisons). These send a sample of the prompts from the logs to the candidate models - either the default choice or set by you. This call goes directly to the model provider (never through me) as any normal LLM call would, and the response is shown and judged to either be better or worse or a tie. It's deliberately small, because I tend to over complicate/think things sometimes: analyze + capture + a few commands, doing three jobs. Cost, quality visibility, routing recommendation. Nothing is hosted. capture is an optional local proxy on your own machine, and there's no endpoint in the path of your data. You can confirm this by checking the source. I included a demo so you can check out the output. It has a synthetic 56k call log (a month's worth) showing how costs can drop from $549.46 to $343.91 a month. A 37.4% saving. Try it: uvx frugon analyze --demo or uv tool install frugon Then point it at your own logs. All feedback is welcome, especially any on the routing/quality logic, or anything else, good or bad. https://bit.ly/4ybqv9T July 7, 2026 at 01:20PM

Show HN: Autoops – Multi-region data and service mesh operated by a Makefile https://bit.ly/4vkxzOW

Show HN: Autoops – Multi-region data and service mesh operated by a Makefile Hi HN, Stefan here. autoops is an infrastructure automation framework I have been using at my previous company and is now opensourced. It has been the base layer running various products and projects, and also for quickly standing up client infra. It works with Debian-based systems (apt) and sets up a WireGuard mesh with peer discovery and built-in DNS (Wesher), a distributed S3-compatible object store (Garage), and a reverse proxy and load balancer (Traefik). It supports service autodiscovery (Traefik-kop) and can be horizontally scaled to up to 150-200 nodes. As a classical example of "roll your own k8s subset using scripting", it is not yet fully integrated and currently, you need 1) to define at least a PyInfra inventory, 2) depending on whether you run containered services, a Docker Compose file, and 3) for horizontal scaling with autodiscovery, a Traefik config. The PyInfra scripts are put together in a Makefile, but that is pretty self explanatory. autoops doesn't trust supply chains, so you need to out-of-band put a couple of binaries in the general assets/ folder, and if you do containers, provide a path that contains directories named after each service and holding its Dockerfile and other build assets. Also, it's almost arm64 compatible (needs binaries for Docker and the crowdsec bouncer), can do NAT traversal (using my fork of Wesher), and container draining (using docker-rollout). Feedback is welcome. https://bit.ly/4p3NmQE July 6, 2026 at 10:59PM

Show HN: Logo Design for Busy Founders https://bit.ly/4eM8SGj

Show HN: Logo Design for Busy Founders General purpose illustration tools like adobe illustrator or affinity have a great amount of flexibility but come at the cost of complexity that isn't needed for a logo design tool. So I trimmed down the fat to a minimal set of 10 tools acting on a logo grid, when combined together makes it easy to build quite a surprising variety of logo marks pretty fast. This was a very interesting project unlike most of the work i've done over the years, this iteration (the 4th) came from progressively whittling down (vs up) affordances, if a combination of tools could do what one did, it was cut, if that tool didn't seem to behave cohesively with the rest (perhaps potentially breaking the user's mental model of the editor) it was cut. Initially i had features like layers, multiple fill colors. Naively i felt my goal was to build a minimal set of tools that achieved "logo-completeness", but i realised that would just give me a terrible Illustrator clone vs balancing learning curve to expressivity. There's still some wonky behaviour related to selecting/cutting, this will be fixed once I can put a finger to what this wonkiness is actually. It exports to SVG, transparent PNG, PSD and more. https://bit.ly/4y6kjA6 July 5, 2026 at 11:50PM

Show HN: Tracking how much of the HN front page is AI-generated https://bit.ly/3R3uswC

Show HN: Tracking how much of the HN front page is AI-generated For the past few months, I've been sending every story that reaches the HN front page through Pangram's AI detector and noting the scores. The reason I made it is that I kept noticing posts that sounded like AI-generated to me. Sometimes the comments pointed it out, sometimes a post was near the top all day and no one said a word. I wondered if the share was really increasing or if I was just primed to see slop everywhere. How it operates: The site identifies the top 30, gets each article, and evaluates the text using Pangram. Besides the live front page view, there are daily and monthly trends, with leaderboards for domains and authors that keep scoring high. I personally find it quite helpful as a sanity check on my own intuition before declaring something AI in the comments. 6,500+ stories in, it turns out the front page is still very human after all, which is the part that shocked me the most. A fraction of 13% of stories were AI flagged over the last 30 days. That's slowly ramping up (roughly a point higher than the previous month) but still not close to the feeling of 'everything is slop now' I had. At the moment it's 1 flagged story out of 30. The flagged ones still manage to get by quite well. One of them is at #6 today with 545 points and a 99% score, and the discussion section is divided on whether it's AI or not. Standard disclaimers: a detector score is not a piece of evidence, false positives do occur, and a high score can also be the result of a human coming up with the ideas and then using a model for the prose. To me, it is an invitation to examine the matter more closely rather than a judgment. Feel free to ask me anything about the setup. And yes, I ran this post through the detector before submitting it. https://bit.ly/4fkFQh2 July 5, 2026 at 08:17AM

Show HN: Reading Assistant Physical Books Meta RayBans Reading technical books is hard. Unknown words, confusing phrases, and misunderstood concepts requires opening your phone, starting Claude, and working with Sonnet through a series of exchanges, before finally getting it. Focusing back on reading after such a context switch can be difficult. Repeated multiple times and your attention span is gone. Fix: An assistant understands your book deeply and answers inquiries through voice while you read, side-stepping the current process entirely. All you have to do is: - Upload a PDF version of your physical book and start reading - Say "Hey Lumos" along with your inquiry ("why does det(A) mean the matrix loses volume?") - Assistant researches the contents of the book and responds - Continue reading until you need help again It's in extreme beta but works well enough where I can't read a book without it.

Would love if you tried it out! https://bit.ly/4p9aiOE July 1, 2026 at 06:30PM

Show HN: Capcat – CLI/TUI to Archive Articles as Markdown and HTML (FOSS) https://bit.ly/44K4bXq

Show HN: Capcat – CLI/TUI to Archive Articles as Markdown and HTML (FOSS) Capcat is a python based CLI/TUI FOSS utility for Ethical archiving of given website or RSS source. The github repo: https://bit.ly/4vemgb0 It is generated with NLP, context-engineering, spec-driven development and LLMs. Fully functional at https://bit.ly/3QDrEq6 , with instructions for usage and documentation. The project started from my personal needs of simple archiving with structure and moved to product design/MVP exercise. I am longtime HN user, and the most value I got in years of reading is always deep in the comments section. For HN Capcat uses the official API, with rate-limits, identifies honesty with clear user agent and skips paywalled content. All usernames are anonymized with a link to the user profile. The content is delivered in Markdown format (Obsidian ready with frontmatter) and optional HTML with dark/light themes. Every source has its own YAML config file for separate control and PDF size limiter. In the folder users have an option to change the HTML theme with a minimal CSS design-system. Please consider that my focus as a product designer is in UX. I have enough of a general culture and software development principles but the code is not validated, and my decisions in building may have a limitation. Feedback is welcomed. Thanks in advance. https://bit.ly/4gdKWN4 July 2, 2026 at 11:37PM

Show HN: C++, Java and C# light-weight-logger https://bit.ly/4biJd5A

Show HN: C++, Java and C# light-weight-logger This is a library I've been working on with versions for C++, java & C# where you make custom formats and Log based on them, for example you could make an ERROR Like this: [ERROR] [date, time-stamp, time-zone]

(file:thread-ID:line) but you would write it like this: // define the master format master_style = "%C[%N]%c%S%G[%D %T %Z]%c %M %G(%F:%t:%L)"; // tell the logger what colour to use for a given name logger.add_format("ERROR", master_style, Colour::RED); so now the [ERROR] part will be red, the time area will be grey, and the location grey, but you could really make any style you wanted. And once you have a master format you could also add different types of logs: logger.add_format("SUCCESS", style_minimal, Colour::GREEN); logger.add_format("INFO", master_style, Colour::CYAN); logger.add_format("WARN", master_style, Colour::YELLOW); also the %S we put in there is actualy a colum padder so you logs will be inline: [INFO] [16/06/2026 10:58:00 AUS Eastern Standard Time] Initializing core subsystem components. (src/main.cpp:1:39) [SUCCESS][16/06/2026 10:58:00 AUS Eastern Standard Time] Database connection established smoothly.

Show HN: Xenoeye – analyze network without AI using netflow, PostgreSQL, Grafana https://bit.ly/4eKAKt2

Show HN: Xenoeye – analyze network without AI using netflow, PostgreSQL, Grafana Sorry for the slightly truncated title. It should have been "Network traffic analysis and monitoring without AI, using netflow-family protocols, PostgreSQL or ClickHouse, Grafana, and some scripts". In 2026, it might seem a bit presumptuous to announce AI-free software on HN. But building a netflow analyzer manually is no less presumptuous! There are quite a few xFlow analyzers out there these days, and I'm constantly reminded of this. But I think there's always room for an alternative approach. After all, that's how software evolves, isn't it? So, how does xenoeye differ from popular (at least from popular open source) analyzers? - The analyzer has a feature called "monitoring objects". For some reason, open-source analyzers rarely use this feature, while commercial ones do. The monitoring object can be a subnet, autonomous system, geo-object (data on geo and AS are taken from external databases), application traffic (protocol, TCP/UDP ports, etc.), VLAN, etc. Almost everything in flow records can be used as a filter for a monitoring object. Of course, object filters can be composite - the classic operations AND, OR, NOT are supported. The analyzer contains a tiny virtual machine that matches each flow to an object. - We don't store all flows. At least for now. It may seem strange, but this is an important feature, especially for large networks. We store aggregated data on monitored objects. The user chooses what to store. It could be just in/out, top talkers, top protocols, etc. The time for which to aggregate data is also specified by the user. Aggregation occurs inside the analyzer. We use a fast trie-based in-memory db. Because of this, the analyzer can process flows quite quickly (hundreds of thousands of FPS per vCPU) and export a measured amount of information to the database. You can easily use even vanilla PostgreSQL. Or ClickHouse with compression. The analyzer is not very resource-intensive; small network traffic can be processed on low-end hardware or in a VM with a small amount of memory. Or you can process large network traffic on a single server, without building clusters. I know of installations with multi-terabit traffic and hundreds of MOs on a single virtual machine (of course they have a high sampling rate on their routers). - We can monitor traffic thresholds being exceeded using moving averages. That is, as soon as an excess is detected, an external script is launched at the same second (actually even faster). This feature is typically used to detect volumetric DoS/DDoS attacks. The scripts announce BGP Blackhole or BGP Flowspec and notify users via messenger. - We don't have our own visualization utility; we use Grafana. Grafana works with PostgreSQL out of the box, although some complex time-series charts require some tinkering with SQL queries. Ok, it's a controversial decision, but users (and we ourselves) are putting up with it for now. I tried to describe the rest in the documentation. Yes, this isn't the first time I've tried to announce this project on HN, and I'm under no illusions - for some reason, hackers aren't very fond of this type of software. Perhaps everyone thinks that the production of netflow analyzers is too boring a matter, there is nothing to discuss. However, if anyone is interested, it would be great to get feedback. What would you do differently than it was done and why? What do you like most about your favorite analyzer that you can't find anywhere else? How did you even see this post? This isn't AI or even a Rust-related thing https://bit.ly/4aqB92t June 29, 2026 at 10:00PM

Show HN: Engye – transfer files between any two devices by scanning a QR code https://bit.ly/3SzSShN

Show HN: Engye – transfer files between any two devices by scanning a QR code Early in April I needed to print some tax forms at the library, first time in forever, and I began to wonder: what's the easiest way to get a file onto a public computer? There are many ways, but most of them involve creating an account somewhere or plugging in a thumb-drive. I use a password manager, so my passwords are long and complicated, not easily typed. I don't want to plug anything into a public computer, nor do I fancy uploading my taxes to some random website. I thought about what a helpful product would looks like, and in about an hour I spun up the first version, https://bit.ly/4oSooDD... : a static Vite TS site, hosted on GitLab Pages, which uses a QR code to connect two instances of the website using WebRTC. Now all I had to do was navigate to a URL on the library computer, scan the generated QR code, choose the tax file on my phone, and the library computer instantly downloaded it. After the library trip, I looked further into this space, and found that no one solved the specific combination of cross-network, no install, no account, no cloud. Snapdrop and PairDrop are similar sites but are LAN-only or require a public room. LocalSend requires installing software on both devices, which makes that impractical for public devices. And other solutions were either hardware locked (AirDrop, Quick Share), required uploading files to the cloud (Google Drive, Dropbox), or sent data through their own servers (Wormhole). So with some determination, night and weekend coding, and plenty of scope creep, we have... Engye, pronounced "an-jee" like the name Angie, is available at https://bit.ly/3SAOXRQ and can be used to do a whole lot with just a QR code and no accounts: - send a file: users download it from your browser tab - collect files: users upload files to your browser/desktop - clipboard share: users share a single text box, good for sharing short text - virtual drive: Engye Drive allows you to create and attach a virtual thumb drive Think I may have gotten carried away with that last one. ¯\_(ツ)_/¯ My honest hope with this was to make thumb drives obsolete for MOST uses. (Almost named this project "We Break Thumb(drive)s" as a reference to the Simpsons, but couldn't get the name to work out.) It's 2026, it should be trivially simple to transfer a document from one device to another! So I decided to make this obvious and simple project, and I think it can be quite helpful for a lot of people. It's not practical to use this app for transferring 4K movies (a large file would crash the browser, since we load the data into memory twice), but for most people's use-cases of transferring a handful of pictures and documents here and there, this project should simplify things a lot. Engye Drive was a fun, nerdy addition after I got the basics working. I really wanted to be able to connect a virtual drive just by scanning a QR code. The web app provides full access to an Engye Drive, and by installing an npm package you can even auto-mount the drive in Finder or Explorer. For security the app uses AES-256-GCM and new IV per each request, so your data is always encrypted between browsers. If TURN or other relays are used, they never see the plaintext, so you're safe from a MITM attack. The encryption key is in the QR code, so only people who scan your code can share data with you. There are no accounts, and closing the browser terminates the connection. If you do need a longer session or offline usage, you can install Android/iPhone apps that run Engye in the background. This project also served as a personal experiment in agentic coding. I designed the app, instructed Claude to implement it, then iteratively developed the app by chatting with Claude over the course of about three months. Code’s on GitLab, AGPL-3.0 — free to use and self-host: https://bit.ly/4gaM43X Happy to hear what others think. https://bit.ly/3SAOXRQ June 28, 2026 at 01:36AM

Show HN: The TypeScript Semantic Layer for ClickHouse https://bit.ly/4oQE76l

Show HN: The TypeScript Semantic Layer for ClickHouse I've built a type-safe semantic layer in code, for ClickHouse. If you're building analytics off ClickHouse in TypeScript, I would love your feedback. With hypequery there is no platform to adopt, no YAML sprawl. It runs where your app runs. Key features: - Define metrics once, reuse them everywhere: Declare dimensions and measures in one place and then pull from the same source of truth. - Compiles to ClickHouse SQL: No service, no proxy, no extra runtime to deploy. It's a library that generates SQL and runs where your app runs. - Multi-tenancy & Authentication ready: Cross-tenant queries are blocked at the query layer, helpers to plug into your existing auth. - Agent-native: A dataset is a declared set of dimensions and measures, so it doubles as an allowlist. Includes an MCP server to hand an LLM a typed catalog to query. - Runtime HTTP entry point: serve() exposes any dataset as an endpoint, so the same type-safe definitions back your dashboards and your API. https://bit.ly/43YBtly June 27, 2026 at 10:37AM

Show HN: Hacker News on a Train Station Style Flip Board Although the page itself is more just fun to have made and look at (I like the flip sound), the fun part is how I made it to verify the (and I hate to say it) vibe host service I've been working on. The recent flip board back and forth's on Twitter (X) are what inspired me. The idea here is that people (like me or you) can create something neat like this, and others can remix it, change it and publish their own version. This is that all in action and it worked great. I wrote a blog about it (the blog is dogfooding, it's just an app hosted on quickish that uses the built in db lib). For the HN version of this flip board I use their firebase api via the built in quickish server functions that make use of the fact that the front-end can get realtime updates (now that you mention firebase) from cloud function db updates. Of course that's over-kill but I wanted to show something fun. You can remix and host your own version for free, just need a google oauth login that's it.

Show HN: DeepSeek Flash inverted the economics of agent products https://bit.ly/4vPuiIJ

Show HN: DeepSeek Flash inverted the economics of agent products There is an adversarial relationship between developers and big model labs. Model labs charged developers higher API prices to subsidize their own agent harness offerings. Think Anthropic charging 5x higher Claude API prices to subsidize consumer subscriptions. So Cursor in a way was subsidizing their own direct competitor. DeepSeek V4 Flash totally inverted this relationship. Now you have a model that beats even Sonnet in some benchmarks and is totally opensourced. Now inference providers are racing to the bottom to optimize and give cheaper hosting. Every player with a non-SOTA is now racing to swap over to stop paying the big model lab tax, even Microsoft is switching Copilot to use DeepSeek. On switching over to Deepseek: - we noticed over a 100x cost decrease while similar or better performance then Gemini 3 Flash - insane saving from the cached input tokens: $0.002/1 Million tokens - both DeepSeek Flash and GLM 5.2 are text-only models, so clearly multimodal training is not worth the additional cost. Language is just a much more efficient sparse representation of the world/reasoning than vision - we had a early bet on a text-only web agent harness, and now with DeepSeek this results in unique cost advantages. - we rewrote our harness as a callable DSL library that a model can generate code to execute on. DeepSeek has proven phenomenal on code generation to drive an agent harness. - I would highly recommend everyone to rewrite their harness to be text-only and callable via executable code leveraging DeepSeek V4 Flash. https://bit.ly/3QJXSzU June 25, 2026 at 11:56PM

Show HN: Monolisa v3 – a typeface for developers and creatives Originally we (Andrey, Marcus, Juho) built MonoLisa in 2020 as we realised there's room for a better monospaced typeface for developers. The key insight was to make the glyphs slightly wider to make more room for design to make letters like m feel less cramped. Since then we've released a variable v2 (2022) and now we're happy to expand the typeface with a new family called MonoLisa Text. The reasoning was to cover *other* use cases beyond coding with this proportional font. We hope you give Monolisa a go as there's a free trial to try. We also welcome feedback! https://bit.ly/4xBScse June 22, 2026 at 03:05PM

Show HN: Wirewright, an experimental symbolic physics environment https://bit.ly/44s0oOg

Show HN: Wirewright, an experimental symbolic physics environment The idea with Wirewright is to treat programs and algorithms as physical mechanisms, as machines or societies of machines inhabiting an immutable symbolic world, and time-step the latter to see what happens. This last part in particular reminds me of cellular automata. Said differently, in Wirewright, programs are modeled as "nouns" or "societies" of interacting "nouns" (think data structures). The world is then subjected to laws of physics -- symbolic physics; which is the only "verb" here (think function). Therefore, in Wirewright, we say that, in a sense, algorithm equals structure and the evolution of structure equals computation. I tend to shorten this to "structure is computation", but this may be incorrect if viewed in isolation. Now, I guess you're wondering what Wirewright actually is . In fact, I see the rules here state that I must tell you what Wirewright is, plainly and clearly. I will try, but beware that at the end of the day, I know as little as you do :^) My hands write, my brains ponder. It's hard for me to say definitively what Wirewright is . Please see the README for several attempts of mine to answer this question. Please see the tutorial(s) if you're interested enough to try and infer that yourself. I'm still not sure the README or the tutorial(s) are answering the exact question, though; I had no feedback yet on most of my work on Wirewright, so any feedback is welcome, other than, I guess, "I don't understand what this is"; this kind of feedback I can generate myself, no offense :^) If there wasn't a public GitHub repo and if I hadn't made a few announcements here and there already, you'd think I'm developing the project in secret. This kind of stuff is not something you ordinarily talk about, you see, especially "in the wild"; or else you'd be quickly labeled eccentric or outright crazy. Anyway. Wirewright is not a framework, not a UI toolkit, not an IDE. It's not a programming language either. I think I'm trying to explore the intersection of different things here, such as cellular automata, term rewriting, symbolic computation, dataflow, etc. I'm also prone to veering off for pages and pages into a genre one could call "folk biology"; biology and especially neurobiology is a huge inspiration for me. Inspiration doesn't mean copying or formal study, of course. In fact, if there are any biologists here, please "shut down" your eyes and ears and all other sensory organs if you decide to explore the depths of the project :^) For me, when I see something interesting in biology, I think, in excitement, "Oh, I want to do that too, I don't care how!" The project has been evolving more or less organically, along with me, so to speak, subsuming a lot of my ideas (but mostly the ideas of others; e.g., Varela, Maturana, Wolfram), and mixing them. I'd say it's a playground of mine which, over the years, has become consistent enough for me not to fear trying to tell the world about it. That is, about two years ago, Wirewright was an amorphous blob I couldn't even describe with analogies. Now I can at least try analogies. All this "symbolic physics" stuff is the product of my most recent work in recognizing where the project actually appears to be heading. Now, as a final disclaimer, please note I'm an amateur in all of the things I'm talking about, from programming to biology to philosophy. So maybe all of this is well-trodden grounds, and I'm coming up with these words and ideas for nothing, and what I'm saying is stupid. Maybe it is. Regardless, I hope at least the synthesis looks interesting to some of you, even if the exact wording and my little philosophy intermissions here and there feel a bit off. Sorry for the long text. https://bit.ly/4uOUn9i June 22, 2026 at 01:15AM
