Show HN: JPDB, GDB for Your Waveforms https://ift.tt/r8aRXip

Show HN: JPDB, GDB for Your Waveforms hey everyone, I've been working on JPDB is a GDB like debugger for waveforms. if you give JPDB a waveform* and some other information, then you can step through the program that was executed when that waveform was created. i say GDB-like because JPDB has it's own GDB client (its called shucks), that implements the client side logic of the GDB protocol faithfully, but doesnt have all of the GDB niceties (like python integration, etc). this allows the project to be specialized on debugging waveforms specifically, when compared to another approach like connecting to a gdb client JPDB integrates with the waveform viewer surfer ( https://ift.tt/4YL8iDp ), so you can look at other signals there. this is still ongoing because the underlying protocol (WCP) is a little Fresh if you're developing your own CPU, give it a shot. Superscalar designs arent supported yet but it would be pretty straightforward, just give me your waves ( i am touching my fingers together villainously as i type this) and i will make it happen also if you want to use system with a "normal" gdb client, the dang library presents a gdbstub server, so you can run that and connect to it. here's a demo but it should work on your local machine if you follow the readme: https://www.youtube.com/watch?v=EOo1aG_wcJg https://ift.tt/7gXJi1N October 1, 2025 at 01:33AM

Show HN: AI that trades speed for reliability in site generation https://ift.tt/7z16NS0

Show HN: AI that trades speed for reliability in site generation I run a small agency and we’ve been building client websites for years. The work is hands-on, repetitive, and time consuming. We tried platforms like Replit and Lovable, but the output didn’t hold up for production use. Things were missing, editing was limited, and reliability was an issue. Out of that frustration we built Zylo, an AI platform that generates production-ready web apps. It is not instant like Lovable (our builds take roughly 15 minutes on average depending on complexity) but we focused on completeness and reliability instead of speed. What Zylo does Generates full stack Next.js projects including frontend, backend, and database setup Built-in domain management so you can bring your own or purchase directly inside Zylo E-commerce system that feels like a lightweight Shopify with product management and categories Stripe integration through API connection for payments How it works under the hood You interact with an AI chatbot that coordinates several agents following the same processes we used manually when building sites Agents generate code, proofread, and check for missing assets or design issues Any build, runtime, or TypeScript errors are automatically caught and repaired before deployment A final agent handles production deployment and gets the project hosted and ready for a domain connection Editing We put a lot of effort into the editing side. There is a live Monaco editor that renders the site. You can click directly on any component, section, or entire page and pass that as context back to the agents for regeneration. This was something we found lacking in other tools and wanted to solve. What’s next We are currently working on a visual workflow builder. Think of something similar to GoHighLevel’s UI, but instead of manually wiring things, the AI fills in the code and functionality behind the scenes. The idea is to let people map out flows visually and have them actually run in production. We would love feedback from the HN crowd. The big trade-off we made is slower build times in exchange for more complete and reliable projects. Do you think that trade-off makes sense, or would speed always win out for you? https://www.myzylo.app September 30, 2025 at 01:03AM

Show HN: Agentsmd – Local preferences and templates for AGENTS.md https://ift.tt/IM042Ja

Show HN: Agentsmd – Local preferences and templates for AGENTS.md Hi HN I built agentsmd for developers who use AGENTS.md but want a way to manage personal preferences and reusable templates on top of the canonical repo version. For example, I don’t want my agents to run npm run dev for Next.js. Another developer might want that step included. Those kinds of preferences should live in my local .agentsmd, not in the shared AGENTS.md. The standard only defines looking at AGENTS.md files, which are git-tracked, so this tool helps get around the problem. Ideally, the AGENTS.md standard should also look at local .agentsmd files to account for local preferences. I've already opened an issue: https://ift.tt/MJt0cN8 I’d love feedback on: - How you separate personal vs. shared guidance in your projects - Whether templates like this would help in your workflow - What other features would make managing AGENTS.md easier Thanks for checking it out! https://ift.tt/ezXyd84 September 30, 2025 at 12:30AM

Show HN: Reddit browser for MCP clients – works with any AI assistant https://ift.tt/zXRVxEA

Show HN: Reddit browser for MCP clients – works with any AI assistant Built this to give AI assistants native Reddit access. No more copy-pasting links. You can ask things like "what's the sentiment on TypeScript vs JavaScript in r/webdev" or "analyze the top posts about GPT-5 today" and get instant analysis. Technical: TypeScript, 3-tier rate limiting (anonymous works fine for most), LRU cache under 50MB. Works with any MCP client, not just Claude. Someone used it to track reactions to H-1B changes across different country subreddits in real-time - that was pretty cool to see. Open to feature requests and contributions welcome!

Show HN: Free developer-first OneNote alternative https://ift.tt/ur6pktW

Show HN: Free developer-first OneNote alternative Hey Everyone, been working on a note-taking app called janta (Just Another Note Taking App) the past few months. You can try it out at app.janta.dev (you will be redirected to app.janta.dev/canvas/temporary, which is the locally-stored whiteboard you can access) I felt limited with OneNote, Excalidraw, and other infinite-canvas style apps, so I built an alternative. You have access to code-editors, Desmos graphs, and rich text editors (SlateJS). This is because the canvas is designed in a way that allows web components to exist on the same layer as pen-strokes, so you can annotate code, circle points-of-inflection, and programmatically generate graphs using matplotlib.pyplot! This is a beta release, and feedback would be awesome! https://app.janta.dev September 29, 2025 at 06:04AM

Show HN: Automatically set real iOS alarms for calendar events https://ift.tt/eOncpl0

Show HN: Automatically set real iOS alarms for calendar events I kept missing appointments and meetings because calendar notifications are too easy to ignore. Alarms, on the other hand, always break through silent mode/DND and force you to acknowledge them — but setting them manually every day was another chore. With iOS 26’s new AlarmKit, I built Beacon: it automatically syncs with your Apple Calendar and converts important events into real iOS alarms. You can define simple rules (like “only events with ‘Interview’ in the title” or “meetings with 3+ attendees”), and Beacon sets the alarms for you — no extra work required. Would love feedback! https://ift.tt/TdivS6e September 29, 2025 at 05:11AM

Show HN: A web version of Pips game (NYT domino game) https://ift.tt/KXUfp7F

Show HN: A web version of Pips game (NYT domino game) Hi everyone, I’m an indie developer learning Next.js and a big fan of the NYT game Pips. Inspired by it, I built https://pipsgamer.com — a responsive web version of Pips with smooth gameplay on both desktop and mobile. What makes this project different from NYT’s version is that you can play it infinitely under three difficulty levels: Easy / Medium / Hard. This is the first time I’ve built a game. Along the way I ran into many difficulties: implementing the game logic, configuring the UI, matching layouts for small and large screens, etc. I spent many lonely nights and sometimes even doubted whether I could complete the whole project. After 24 days of persistent effort, the project is finally finished. No signup required — just go and play. If you try it out I’d really appreciate your feedback: what you like, what bugs you see, what could be improved. Thanks! https://pipsgamer.com September 27, 2025 at 05:23AM

Show HN: Prism – Let browser agents access any app https://ift.tt/hPC1jwn

Show HN: Prism – Let browser agents access any app Hey HN, We’re Alex, Land, and Rajit. We’re building Prism (prismai.sh), a tool that helps browser agents authenticate onto websites with user credentials. Developers pass in credentials, Prism logs into a website on their behalf, and hands them back the cookies so they have an authenticated session. Here’s an example of how developers can use Prism to complete username/password flows ( https://youtu.be/SEtVUnWnxuE ), and here’s an example of how developers can use Prism to complete login flows that require an OTP code ( https://youtu.be/fe9w9PvrwH0 ). We spoke to browser agent developers and saw people copying and pasting credentials and even credit card numbers directly into model system prompts. We were surprised that there wasn’t a better way to give agents access to websites on a human’s behalf. Moreover, we noticed that every company had to build infrastructure to manage OTP, TOTP, and MFA and that auth remained a significant hurdle in agent reliability. We wondered if this was a boring part of the problem of building web automations that someone could automate away. We started working with Casco, an autonomous security testing company, to enable their agent to access customer sites. Before a pentest, Casco makes a request to Prism’s API specifying test user credentials, a domain, and a login method. For example, give me an authenticated session for the account rajit@prismai.sh for OpenAI via OTP code over email. Our agent logs in on their behalf (without exposing credentials to a model), and we download the cookies and send them back in the response. To maintain speed and reliability, we use playwright in most cases to login (which gives us speed), and we fallback to AI on failure (which gives us reliability). We have a number of websites we support out of the box and add new scripts as the number of websites we need to support grows. We are working on a way for the agent to update the existing playwright script on failure, so our scripts always stay up to date. To try our api, you can use our API playground docs.prismai.sh/api-reference/endpoint/login to sign into x.com with the following API key: pk_54abb1cd0a637eb973ed690416e71a953e98f2ea839cf16529bbfa41a41bc016 . We’d love to learn more about how other developers give agents access to their accounts. We look forward to everyone’s feedback and comments. https://prismai.sh September 25, 2025 at 11:32PM

Show HN: Selling numbered rocks, you get whatever's next in sequence I had this idea: what if you removed customer choice entirely? So I'm selling rocks for $49.99. You can't pick which one. You just get rock #000001, then the next person gets #000002, etc. No returns, no exchanges. Currently sourcing rocks and taking pre-orders for November. Each one gets weighed, photographed, numbered, and comes with a certificate. Could be a 1-gram pebble or a 10kg boulder - same price. It's the opposite of how everything online works. Amazon shows you a million options, I'm giving you zero. Wondering if that constraint makes it more interesting or if I'm just making it harder for no reason. No social media, no marketing, barely any explanation on the site. Just: here's a rock, here's a number, here's the price. Honestly not sure if anyone will actually buy these, but the pre-orders will tell me if removing choice kills demand or creates it. https://weight.rocks https://weight.rocks September 23, 2025 at 06:35AM

Show HN: Zenode – an AI-powered electronic component search engine https://ift.tt/JpticB6

Show HN: Zenode – an AI-powered electronic component search engine TL;DR - My cofounder Collin and I built an AI version of Digi-Key to help PCB designers find and use parts, except with a way bigger catalog, modern refinement tools, and an AI that can actually read the damn datasheets for you. *The problem* Modern circuit board design is filled with absurdly tedious tasks, where one small mistake can brick a project and cost thousands. The worst (in our opinion) is reading datasheets, which eats up to 25% of the first part of any project: 1. First, you slog through catalogs to find viable parts, using search tools that are still stuck in the dark ages. There are ~80M unique components in today’s supply chain, yet the tools we have to look through them are just digitized versions of the same paper catalogs our grandparents got in the mail. 2. During the design, you spend a ton of time flipping between different 10-100-page PDFs for every component in every subcircuit, hoping like hell you don’t miss some tiny spec in a footnote somewhere that kills your design. 3. And god help you when the requirements inevitably change and now you have to figure out what subsystems are affected! *What we built* Zenode is an AI-powered electronics search engine that actually helps engineers find and understand components. Our core features: 1. Largest and Deepest Part Catalog → We have merged dozens of existing part catalogs and documents from major distributors and manufacturers 2. Discovery Search → natural language queries to quickly find categories, set filters, and rank results 3. Modern Parametric Filters → rebuilt from scratch to move off the string values pervasive in industry and build numeric ranges that actually work. 4. Interactive Documents → AI constrained to a single part’s datasheet/manuals. Ask a question, get the answer with a highlighted source for quick reference. 5. Deep Dive → search across dozens of parts simultaneously (“what’s the lowest-power accelerometer available?”) instead of slogging one by one. *What we learned* 1. By far the hardest part of the last 2 years has been wrangling 3 TB of messy, inconsistent data into something usable. We had to teach the AI how to handle hand-drawn figures, normalize different unit variables and names that mean the same thing, and navigate conflicting information present between different datasheet versions of the same part. It’s been a nightmare 2. We originally built custom PDF parsers and AI extractors, which were best in class for ~3 months until generalized AI passed them. So we stopped reinventing wheels and doubled down on data quality instead. 3. The killer feature wasn’t the AI searching a single part, but what we heard repeatedly from users is that they want the AI to read across multiple parts, hence why we’ve launched deep dive! *Where it’s strong* - Speed: rips through a 1,000-page microcontroller datasheet in seconds. - Breadth: 40M+ part sources unified into one catalog, and more than just datasheets, application notes, errata, etc. - Comparisons: Deep Dive lets you ask across multiple parts, not just one at a time. *Where it’s not* - Pricing/availability: currently outdated (for now we expect folks to check existing aggregators like Octopart). - Accuracy: good enough to match my mediocre skills; not yet at Collin's level, but we're starting tuning and this will improve rapidly! *Try it* It’s live today (zenode.ai). Sign up for a free account and If you put “Hacker News” in during signup in the “where did you hear about us” field, we’ll give you 1,000 bonus credits (once we finish building that, so sometime this week ). *Feedback we’d love* 1. Should Deep Dive results auto-become filters you can refine further? 2. Do you want the ability to mark preferred parts / exclude others? 3. Is “Deep Dive on a BOM” (alt discovery + manufacturability checks on a list of known components from different categories) the killer feature? https://zenode.ai/ September 22, 2025 at 06:57PM

Show HN: The Atlas – I Built a 3D Universe Simulation with Python and Three.js https://ift.tt/ira5DRI

Show HN: The Atlas – I Built a 3D Universe Simulation with Python and Three.js Hi HN! I’ve spent the summer of the past 2 years building The Atlas, a procedural universe simulator that generates 1 sextillion galaxies (10²¹) from a single mathematical seed. Think No Man’s Sky meets theoretical physics, but running entirely in your browser. Everything is purely deterministic, the universe is calculated from SHA-256 hashed seeds using the golden ratio as primordial constant. There’s no database, no pre-saved data, just pure math. Time itself is treated as a coordinate, so the universe exists as a 4D structure where any moment can be computed on demand. Shut it down for weeks, restart, and planets have still been orbiting. Open the same world on multiple devices and you’ll see identical cloud formations, lava flows, even particle effects—always perfectly synchronized (if your clocks are synced). The simulation applies real physics, Kepler’s laws, tidal locking, Roche limits, hydrostatic relaxation for moons, and orbital temperature variations. Scale is mind-boggling, 300 tredecillion potential planets, far beyond anything that could ever be explored. The backend runs on Python/Flask with Hypercorn, the frontend on React + Three.js, connected via a custom MIT-licensed “vite-fusion” plugin we made. Everything is generated in real time, no storage needed. The Atlas includes 26+ planet types, fictional elements, moons evolving over geological timescales, and rare life forms that display Arecibo-style messages when analyzed. There’s resource mining and spaceship progression as gamification features. At its core, it’s a playable implementation of Einstein’s block universe theory, all moments exist simultaneously in the mathematical structure, you’re just moving through different temporal slices. You can try the live demo or run your own universe locally. When installed, you can choose between Core Continuum (a shared seed universe evolving since 1986, my birth year) or Design the Multiverse (your own unique cosmos with a fresh seed). I’d love feedback on the procedural generation algorithms and ideas for expanding the physics simulation! - GitHub: https://ift.tt/yJbwZGz - Docker: bansheetech/atlas:latest - Demo: https://the-atlas.koyeb.app - Alt Demo: https://ift.tt/KePmSC3 Thanks for reading this far! <3 https://github.com/SurceBeats/Atlas September 21, 2025 at 07:56PM

Show HN: Devsyringe – automate injecting dynamic values into static files https://ift.tt/VMmXUEP

Show HN: Devsyringe – automate injecting dynamic values into static files Tired of manually copying tunnel URLs, API tokens, or other dynamic values into config files? Even small tasks like this break flow and are error-prone. I built Devsyringe, a small Go CLI that automates this process. You define rules in a simple YAML file, run a command, and it updates multiple static files automatically. It works for tunnels, API keys, documentation, CI/CD configs — anywhere dynamic values need injecting. I’d love to hear how others handle injecting dynamic values into static files in their workflows.

Show HN: Continuum Game (68k Mac) Ported to JavaScript https://ift.tt/iX1AGna

Show HN: Continuum Game (68k Mac) Ported to JavaScript This was an interesting porting project for a few reasons (IMO): - The original game is/was awesome and, from a programming perspective, a wonder -- smooth scrolling arcade game on a 128kb Mac in 1984... - The port was done with a lot of help from AI (mostly Claude Code, but some Gemini CLI as well). I'm a programmer; it wasn't vibe-coded. But I couldn't have done the port of 68k assembly without it. FWIW, Claude seemed better at actually porting the 68k assembly but Gemini was better at finding bugs. YMMV. - I love Redux and Redux Toolkit for state management. For the port, I put the entire game state in Redux, including all the physics, movement, etc. Every thing that happens in the game is a little redux action. You can watch the whole game get played in the RTK debugger. For some reason that makes me happy. I've released all my code as MIT. Would love to make a "modern" version some day, but for now I've just tried to be faithful to the original. There are a few bugs, noted as issues in the github repo. Feel free to add more. https://continuumjs.com September 18, 2025 at 09:51PM

Show HN: MeldSecurity – Run Popular Security Tools in the Browser (Free) Hi all! A few things of note -- I want this to remain a freemium service, where a reasonable amount of scans / capabilities are free per month etc. This is a passion project for helping people get access to security tooling that don't have the time/budget/etc to manage their own infrastructure. At the same time, I am paying a lot out of pocket to make this work, so I have added a credit system for users to support the cause at large. I don't have much $$$ for bounties, but I am willing to pay what I can. If you find a security issue on the site, please report it via the contact info on https://ift.tt/v7KVnay I've got a roadmap of security tools to add to the toolbox, such as Dependency Scanners (E.g Trivy), Log Analyzers, secrets scanners, etc. If there's something you'd like added to the toolbox, let me know! Also if you need more credits after the sign up bonus, just open a support case and ask for it and I will add some to your account! (obviously purchasing a credits package is greatly appreciated ;)) Anyways, any feedback would be greatly appreciated! https://ift.tt/FXlpyBC September 18, 2025 at 12:15AM

Show HN: I built a tool to visually manage my LLM prompt templates and save them https://ift.tt/L3MU0l5

Show HN: I built a tool to visually manage my LLM prompt templates and save them This is Prompt Canvas - a simple, open-source web app that lets you visually build LLM prompt templates as YAML schemas and then generate complete prompts by populating values in the templates. It’s based on a single HTML file with no real privacy concerns and everything is portable thanks to YAML exports. Check out the example in the dropdown and read the guide to see how it works: https://ift.tt/K2pnVsO LLMs like structure and I found that generating prompts like this is an easy way of giving it to them. It can be useful if you’re doing a degree of prompt engineering and you want to test small variations in your prompts; or if you have a use case where you submit the same promps many times but with some input variations. I found that browsing to a YAML file and tweaking one parameter for a particular job is much cleaner than a web of Notion pages which is what I had before. Some thought and iteration has gone into the templating engine but everything is still early stage! Some of it is opinionated, and some of it is meant to be quite extensible to different use cases. Let me know if it makes sense. I built this mostly with Gemini 2.5 Pro out of my own necessity. Would love to know if it's useful for you!

Show HN: Helios, an open-source distributed AI network using idle community GPUs https://ift.tt/u9VLm1Z

Show HN: Helios, an open-source distributed AI network using idle community GPUs Hi Hacker News, I'm the creator of Helios, and I'm excited (and a bit nervous) to share it with you all. The "Why": Like many of you, I've been fascinated by the power of modern AI models, but frustrated by the high cost and centralization of GPU resources. I started wondering if we could apply the old-school distributed computing model (like SETI@home or Folding@home) to the modern AI stack. The goal was to build a network where anyone could contribute their idle compute power and, in return, get access to a powerful, multi-modal AI. The "What": Helios is an open-source platform to build that network. It consists of two main parts: an orchestrator server that manages a job queue and the workers, and a client-side worker that anyone can install on Windows or Linux. Users run the worker, contribute resources, and this forms a global, decentralized supercomputer capable of handling text, image, and audio tasks. The "How" (Tech Details): Architecture: It’s a classic Orchestrator-Worker model, written entirely in Python. The Orchestrator (orchestrator.py) is the brain, handling job distribution, worker registration, and a simple web UI. The Worker (worker.py) is the muscle that users run on their machines. Proof-of-Contribution (No Crypto!): This is the core access mechanism. To prevent spam and freeloading, you can only submit jobs to the network if you are an active, contributing worker with a good reputation. It's not based on tokens or blockchain; it's a simple, fair system based on participation. Dynamic Experts: Workers don't come pre-loaded with every model. The Orchestrator assigns AI models (e.g., a specific translation model, an image captioning model) to workers dynamically based on the current job queue. These models are pulled directly from the Hugging Face Hub, keeping the worker client lightweight. Multi-Modality: It's designed to route different job types (text, audio, image) to workers that have the appropriate models and resources available. This is very much an experimental, v1.0 project. I know there are huge challenges, especially around security (sandboxing tasks is a major next step), but I wanted to get a working prototype out there to see if the idea resonates with the community. I'd love to get your feedback on the architecture, the concept of Proof-of-Contribution, and any suggestions you might have. GitHub Repo (Code is here): https://ift.tt/dx5yVTr Project Page (Demo & Docs): https://ift.tt/PIqNFvo... Installers (.exe/.tar.gz): https://ift.tt/iJ5jSwF...

Show HN: Datadef.io – Canvas for data lineage and metadata management https://ift.tt/4htmsYN

Show HN: Datadef.io – Canvas for data lineage and metadata management Hi HN, I’ve been working on https://datadef.io , a tool to help data team (engineer, architect, project manager) make sense of their data universe. The problem: - Data models (dbt, SQL, warehouses) often grow into a tangled mess of tables, joins, and undocumented assumptions. - Lineage is either scattered across tools or missing entirely. - Documentation is usually an afterthought (and gets outdated fast). Datadef.io aims to fix that by providing: - Interactive canvas to map tables, relationships, and indicators. - Automatic lineage visualization to trace dependencies. - Metadata management: define table/column-level details, ownership, and KPIs. - AI-generated documentation that stays in sync with your models. - Export/share features so asset managers, analysts, and other teams don’t get lost in spreadsheets or PDFs. It’s still early, and I’d love feedback from the HN community. In particular: What’s missing for you in lineage/metadata/documentation tools? How would you want to integrate a tool like this into your workflow (dbt, Databricks, Power BI, etc.)? I’d really appreciate your thoughts, feature requests, and criticism. Thanks! https://datadef.io/ September 14, 2025 at 10:29PM

Show HN: From selling AI to QA teams to building a smooth test-management app https://ift.tt/KL5xhNb

Show HN: From selling AI to QA teams to building a smooth test-management app Hey HN, Bootstrapped founder here. I've got a bit of a story for you. We started desplega.ai to build a sophisticated AI platform that could automate E2E testing. We spent the last few months talking to dozens of QA leaders, and trying to learn what are their actual challenges. We've got one consistent feedback from large teams: their daily reality is a living hell of slow, clunky tools. We're talking about teams at major companies still managing tests on spreadsheets. Or they're stuck in a Jira instance so customized and slow you can “make a full pot of coffee” while a page loads (and that’s why they acquired arc! t3.gg said it first). On top of that, they're paying 2k/mo+!? for these tools that feel like they were designed in ‘05. Soon, it became obvious that our AI tool was way too advanced for them, and why it was much easier for younger startups to start using us. But we didn't want to give up on them just yet so... Because I grew up when the internet was still free, and I actually miss that a lot, we decided to create a free test management tool. Our vision is still AI, but we learned AI is not the silver bullet large teams are wishing for. (We wrote something about it at https://ift.tt/XFLl1uM ). Our hypothesis right now is that we can be that team building the right tools for each QA team, leveraging AI. We would love to hear your thoughts on (a) Should we make the project open-source? Any key features? (b) Would you ever trust an entity to do your QA first pass? Cheers, https://ift.tt/zY5xUa7 September 14, 2025 at 10:42PM

Show HN: 47jobs – A Fiverr/Upwork for AI Agents Hi HN, I’ve been working on something I’d love to share: 47jobs ( https://47jobs.com ) – a marketplace where you can hire AI agents to do tasks instead of human freelancers. Why? I kept noticing that many tasks on Upwork/Fiverr—coding, content generation, data analysis, automation—can now be handled by AI in minutes, not hours. But there wasn’t a platform built around hiring AI directly. So I built 47jobs: 100% AI agents doing the work (no humans in the loop). Jobs get delivered 10x faster, at transparent prices. You can “hire” an agent for coding, automation, research, etc. I’d love your thoughts: Does a pure AI-agent marketplace make sense? What types of jobs would you want AI agents to handle first? Any UX or trust issues you’d expect with this model? This is an early version, and I’m here to learn from your feedback. Thanks! https://47jobs.xyz September 12, 2025 at 11:59PM

Show HN: Flox – Nvidia CUDA available for the Nix ecosystem https://ift.tt/M20HBRI

Show HN: Flox – Nvidia CUDA available for the Nix ecosystem Hey Everyone! Ron here, part of the NixOS Foundation and building Flox. Just coming out of this years NixCon and pretty excited to show hn below :) As of today, NVIDIA officially recognizes Canonical, SUSE, CIQ, and Nix—via Flox—as supported distributors for CUDA. Full blog - https://ift.tt/9ogUvIQ... This is a huge win for the Nix community. For years, CUDA on Nix was possible but painful—builds could take hours, and redistributing prebuilt binaries was blocked by NVIDIA's licensing requirements. NVIDIA's growing engagement with key Linux distributions reflects the company's evolution in working with open source communities. Now, for the first time, NVIDIA is allowing these vendors to package and serve the CUDA Toolkit and CUDA-accelerated packages directly from their package repositories. That means Ubuntu users can get CUDA via `apt`, SUSE users via `zypper`, Rocky Linux users via `dnf`, and Nix users simply by declaring CUDA dependencies in their Nix expressions, `shell.nix` files, or flakes. Across all four platforms, developers can now pull in prebuilt, prepatched CUDA software—including huge packages like PyTorch, TensorFlow, TensorRT, OpenCV, ffmpeg, and more. On Nix (my own bias showing), setup is straightforward: just add Flox's cache as an `extra-substituter` in your `nix.conf` or `configuration.nix`. https://ift.tt/uXxw4oL September 11, 2025 at 12:24AM

Show HN: Haystack – Review pull requests like you wrote them yourself https://ift.tt/Y5toWZj

Show HN: Haystack – Review pull requests like you wrote them yourself Hi HN! We’re Akshay and Jake. We put together a tool called Haystack to make pull requests straightforward to read. What Haystack does: -- Builds a clear narrative. Changes in Haystack aren’t just arranged as unordered diffs. Instead, they unfold in a logical order, each paired with an explanation in plain, precise language -- Focuses attention where it counts. Routine plumbing and refactors are put into skimmable sections so you can spend your time on design and correctness -- Provides full cross-file context. Every new or changed function/variable is traced across the codebase, showing how it’s used beyond the immediate diff Here’s a quick demo: https://youtu.be/w5Lq5wBUS-I If you’d like to give it a spin, head over to haystackeditor.com/review! We set up some demo PRs that you should be able to understand and review even if you’ve never seen the repos before! We used to work at big companies, where reviewing non-trivial pull requests felt like reading a book with its pages out of order. We would jump and scroll between files, trying to piece together the author’s intent before we could even start reviewing. And, as authors, we would spend time to restructure our own commits just to make them readable. AI has made this even trickier. Today it’s not uncommon for a pull request to contain code the author doesn’t fully understand themselves! So, we built Haystack to help reviewers spend less time untangling code and more time giving meaningful feedback. We would love to hear about whether it gets the job done for you! How we got here: Haystack began as (yet another) VS Code fork where we experimented with visualizing code changes on a canvas. At first, it was a neat way to show how pieces of code worked together. But customers started laying out their entire codebase just to make sense of it. That’s when we realized the deeper problem: understanding a codebase is hard, and engineers need better ways to quickly understand unfamiliar code. As we kept building, another insight emerged: with AI woven into workflows, engineers don’t always need to master every corner of a codebase to ship features. But in code review, deep and continuous context still matters, especially to separate what’s important to review from plumbing and follow-on changes. So we pivoted. We took what we’d learned and worked closely with engineers to refine the idea. We started with simple code analysis (using language servers, tree-sitter, etc.) to show how changes relate. Then we added AI to explain and organize those changes and to trace how data moves through a pull request. Finally, we fused the two by empowering AI agents to use static analyses. Step by step, that became the Haystack we’re showing today. We’d love to hear your thoughts, feedback, or suggestions! https://ift.tt/gPASFeH September 10, 2025 at 10:21PM

We're also Open Source so feel free to check our GitHub Repository- https://ift.tt/StTLrE3 . The journey hasn't exactly been easy, we've been criticized by a lot saying that whatever we're doing is impractical and that we're too ambitious. Regardless, we've been committed to reach our goal. Here to answer all questions and doubts. Answering one question beforehand because we know someone is going to ask it - Q: Why use your own kernel/ Why don't you use Linux/ Why are you trying to reinvent the wheel? A: Using our own kernel helps us get rid of the baggage of legacy codes, bring the most optimal performance on our target hardware (XR/AR/VR) and achieve more efficiency than what we would've achieved on an existing kernel. We're not trying to reinvent the wheel, but just building Formula One racing tyres for it. https://ift.tt/F8N3gJn September 7, 2025 at 03:09PM

Show HN: Evalyze – AI investor matching from your pitch deck (feedback welcome) I used to work in VC and watched good teams lose months chasing the wrong investors. I’m building Evalyze to make the unglamorous parts faster and more precise. After sign-up (email only, no card) you can: - upload a deck or paste your site - get a ranked list of relevant VCs/angels with a short “why” for each What’s different: instead of dumping a big list, we try to explain why an investor fits based on stage, sector, check size, and portfolio patterns. It’s far from perfect and we want blunt feedback before opening wider. Limits to know: - newer funds and emerging managers can be underrepresented - geo nuances are still rough - matching can over-weight buzzwords if the deck is vague I’d love critique on the ranking logic, signals you’d add/remove, and any privacy concerns. If you don’t want to upload a deck, there’s a sample you can use to see the flow. I’ll be here replying and shipping fixes as comments come in. https://ift.tt/Ek1r74i September 6, 2025 at 09:40PM

Show HN: 60-Second Linux Analysis, Supercharged with Nix and LLMs https://ift.tt/Fp7siS0

Show HN: 60-Second Linux Analysis, Supercharged with Nix and LLMs Hello HN, I'm sharing a little open-source utility I wrote recently. I'm a huge fan of Brendan Gregg's "BPF Performance Tools" book. However, every time I SSH into a fresh server, most of the diagnostic tools aren't installed there and installing them can be really annoying. I decided to use Nix package manager and LLMs to make this process straightforward. My utility first downloads a "toolbox" of Linux utilities (built with Nix), runs Brendan Gregg's famous "60-second Linux analysis" playbook and then summarizes the results with an LLM. So "60-second Linux analysis" now becomes a single one-line command and actually takes less than 60 seconds! The utility can execute all commands in parallel and the LLM can analyze them faster than a human would. I have a few ideas for the future, for example implementing more powerful playbooks - thanks to Nix I can easily bundle all tools I need and LLMs have no trouble analyzing outputs of tens of commands. I'd love to get your feedback and hear any ideas you have. Thanks for checking it out. You can launch the utility with this command: $ curl -fsSL https://ift.tt/Zsrdupq | sh https://ift.tt/oHPtBLD September 6, 2025 at 07:53PM

Show HN: CompareGPT – Spotting Hallucinations by Comparing Multiple LLMs Hi HN I’m Tina. One frustration I keep running into with LLMs is hallucinations: answers that sound confident but are fabricated. Fake citations, wrong numbers, even entire “system reports.” So I’ve been building CompareGPT, which tries to make AI outputs more trustworthy by: Putting multiple LLMs side by side for the same query Making it easy to see consistency (or lack of it) Helping catch hallucinations before they waste time or cause harm link here： https://ift.tt/2hBJ0p7 . We’ve opened a waitlist and would love feedback, especially from folks working with LLMs in research, finance, or law. Thanks! September 6, 2025 at 03:26AM

Show HN: I built a public and open llms.txt endpoint for every domain https://ift.tt/fl3CpaJ

Show HN: I built a public and open llms.txt endpoint for every domain And yes, I know, literally no AI uses llms.txt right now. But hear me out: if you want it just in case, or if you would like to add your sites to some llms.txt directories, you can use this endpoint. That way, you do not need to keep updating your own llms.txt, especially as I improve the API. Here is how it works: Enter any domain: https://get.llms.page/{example.com}/llms.txt The API will parse your homepage (if allowed in robots). Using internal links, descriptions, and other metadata, it will generate an Markdown llms.txt file. It does not rely on AI, because I want it to be fast and free. The API is open, free, runs on a CDN, and is powered by Cloudflare Workers for speed. I plan to open source the no-AI llms.txt generator later, since there is still a lot to improve. If you want to try it out or see some usage examples, visit: https://llms.page Let me know what you think! https://llms.page/ September 6, 2025 at 12:15AM

Show HN: A small browser game (PC only) built with Phaser 3 https://ift.tt/bVdT6Bw

Show HN: A small browser game (PC only) built with Phaser 3 Hi HN! This is my first game — something I’ve always wanted to do. It’s a small browser game built with Phaser 3, React, and the phaser template ( https://ift.tt/mFPyBDn ). I made it in 2 days (like 8 hours in total real time) using gemini-cli. About 90% of the code was generated with AI, but I learned a lot by making fine tweaks. It only works on PC since it’s a typical WASD + R (reload) shooter. I’d love feedback on: - Gameplay (is it fun, too hard?) - Ideas for new features Thanks in advance! ps: I used cubes as a prototype, but now I kind of like them. Should I keep them or implement proper sprites? https://cubic-zombies.pages.dev/ September 5, 2025 at 01:14AM

Show HN: Trending rust NTP inspection CLI https://ift.tt/7e4Tx2M

Show HN: Trending rust NTP inspection CLI Hi y’all, Just came across a crate on crates.io that recently hit v1.0.0. It’s called rkik - basically a "dig for NTP". I hadn’t seen a tool like this in Rust before. Looks pretty handy: it can query and compare NTP servers, output JSON for monitoring, and even run continuous checks. Seems to be getting some traction in the Rust community - might be worth a look if you’re into System administration, networking or DevOps. https://ift.tt/68TnlaZ September 3, 2025 at 11:19PM

Show HN: Provably secure vibe coding is now a thing Don't get your knickers in a knot. We were surprised too. We are the team behind TideCloak which we shared on HN previously ( https://ift.tt/4s9OudZ ). This time we ran an experiment. What happens when you apply a fundamentally different security model to the worst possible development process? Behold... SecureAF https://ift.tt/wlD1Tzg Build video 6 mins https://youtu.be/tx5MsJ3jeQw The code and UI are questionable and the quality assurance is non-existent. But the security model holds by treating even us as malicious, keeping authority over data out of reach for everyone except the rightful user. Can you actually use SecureAF? Hell no. We built it in 20 minutes and never tested it. What's wrong with you? What you reckon? https://ift.tt/wlD1Tzg September 3, 2025 at 12:56AM

Show HN: My first Go project, a useless animated bunny sign for your terminal https://ift.tt/n2EgPw4

Show HN: My first Go project, a useless animated bunny sign for your terminal Hi HN, I wanted to share my very first (insignificant) project written in Go: a little CLI tool that displays messages with an animated bunny holding a sign. I wanted to learn Go and needed a small, fun project to get my hands dirty with the language and the process of building and distributing a CLI. I've built a similar tool in JavaScript before so I thought porting it would be a great learning exercise. This was a dive into Go's basics for me, from package structure and CLI flag parsing to building binaries for different platforms (never did that on my JS projects). I'm starting to understand why Go is so praised: it's standard library is huge compared with other languages. One thing that really impressed me was the idea (at some point of this journey) to develop a functionality by myself (where in the javascript original project I choose to use an external library), here with the opportunities that std lib was giving me I thought "why don't try to create the function by miself?" and it worked! In the Js version I used the nodejs "log-update", here I write a dedicated pkg. I know it's a bit silly, but I could see it being used to add some fun to build scripts or idk highlight important log messages, or just make a colleague smile. It's easy to install if you have Go set up: go install github.com/fsgreco/go-bunny-sign/cmd/bunnysign@latest Since I'm new to Go, I would genuinely appreciate any feedback on the code, project structure, or Go best practices. The README also lists my planned next steps, like adding tests and setting up CI better. Thanks for taking a look! https://ift.tt/WOR2xzX August 31, 2025 at 05:16PM

Show HN: Neuron – Cognitive Multi-Agent Architecture for Reasoning Most orchestration frameworks today still behave like fragile chains — they break when faced with contradictions, long-term memory, or dynamic routing. Neuron is a cognitive multi-agent architecture that thinks in circuits instead of chains. Multiple agents collaborate in parallel, adapt their pathways in real time, and keep persistent context across extended interactions. Key components Agents: Intake, Reasoning, Response, Memory Circuits: Dynamic routing instead of linear chaining Memory: Episodic + contextual persistence Monitoring: Full reasoning traces for observability Why it matters Handles contradictory inputs without collapsing Maintains state across extended sessions Parallel coordination for complex reasoning tasks Transparent logs for debugging & trust GitHub repo: https://ift.tt/CWBpX2H Evaluation Notebook: https://ift.tt/f9rLdYJ...

Show HN: Use "-f**k" to kill Google AI Overview https://ift.tt/RfWqPoX

Show HN: Use "-f**k" to kill Google AI Overview Not sure this is the right way to post this, but I'm sure quite a few people are as frustrated as I am by the AI enshittification of Google search and would like to know this. I accidentally discovered in a fit of rage against Google Search that if you add an expletive to a search term, the SERP will avoid showing ads and also an AI overview. The good thing is that it works also with the "-" (minus) operator, so you can make sure the expletive is actually not included in the result pages. Try it yourself: search for a fairly generic query that gives you ads and AI overview, and add "-f*k" at the end, uncensored of course. Enjoy a much better search experience. It might be placebo, but it feels like the results are actually better sorted. Edit: edited to avoid HN pro-expletives filter :D September 1, 2025 at 12:54PM
