Show HN: wasque – Lightweight Cloudlare Warp Proxy Container for Linux https://ift.tt/KkQSwV6

Show HN: wasque – Lightweight Cloudlare Warp Proxy Container for Linux Lightweight, unofficial Docker container for the official Cloudflare WARP Linux CLI client. Easily expose a SOCKS5 proxy from within a container—no elevated privileges required! My previous project unofficial WARP client, usque ( https://ift.tt/MCumVLd ) got great reception so far and Cloudflare recently published HTTP/2 fallback support on their MASQUE protocol. I needed a way to run their official clients in a reproducible, lightweight fashion so that's when wasque was born. It's a really simple docker container that ships their official client and exposes it as a SOCKS5 proxy. PS: For now the HTTP/2 fallback seems broken for me in their official Linux and Android clients, I already opened a ticket ( https://ift.tt/ey1z7BA... ). But regular HTTP/3 MASQUE works well. https://ift.tt/pTUWu9w June 20, 2025 at 11:11PM

Show HN: Inspect and extract files from MSI installers directly in your browser https://ift.tt/jx1CAhW

Show HN: Inspect and extract files from MSI installers directly in your browser Hey everyone! I'm excited to share a small web app I built that allows you to view and extract the contents of Windows MSI installers directly in your browser. It's essentially a web-based "lessmsi" powered by Pyodide. You can try it out at: https://ift.tt/WH6Yfoc My motivation for building this was from part of my day job -- I often get Windows MSI installers and need to extract files while preserving the relative directory structure and filenames, as they would appear after a full installation. The existing tools I found were good but limited in which platforms they support: lessmsi works great on Windows, while msitools works for Linux/macOS. Neither is a truly cross-platform solution that works on any major OS. So we developed pymsi (a pure Python library, available on GitHub at https://ift.tt/67r5G0d ) to handle reading and extracting MSI files from Python. Then I realized that since pymsi has no native dependencies, it could potentially run in a web browser using Pyodide. After a bit of "vibe coding" and fixing some "hallucinated" functions/classes that don't exist in pymsi, the result was this client-side web app. If you need an MSI file to experiment with, older versions of PowerToys included the installer in .msi form, such as this one: https://ift.tt/LuKJ7Ai.... Note that the underlying pymsi library hasn't been extensively tested against a bunch of MSI installers yet, so there might still be lingering bugs. If you come across any issues, please don't hesitate to report them in on the GitHub repository ( https://ift.tt/iJHhmS1 ). I'd love to hear your feedback and answer any questions! https://ift.tt/WH6Yfoc June 21, 2025 at 12:04AM

Show HN: RM2000 Tape Recorder, an audio sampler for macOS https://ift.tt/w32THXo

Show HN: RM2000 Tape Recorder, an audio sampler for macOS RM2000 Tape Recorder makes it stupid simple to grab audio samples and organize them: just record the sample, give it a title (and maybe some tags), and it is saved neatly into a directory of your choosing. I'm a huge datahoarder and have always appreciated tools / services like PureRef and Are.na which help me make sense of everything I collect. Those services concern themselves with images and video - I wondered, why can't the same be done with music and audiofiles? I actually got the inspiration for the filenaming scheme from the Emacs Denote package - every sample is saved in the format of title--tag1--tag2.mp3. Emacs Denote does something similar, for example an identifier--title--keywords.org . I chose this method as any file browser with fuzzy search can search through samples, i.e. - the Ableton file browser. Just search up some of the tags, and a title, and you'll be able to find your sample. I wanted this app to look good, as well (and is why I spent so much time making it!) The app is made with a mix of SwiftUI and AppKit, while the assets were rendered in Sketch I appreciate your time and I'd love to hear your thoughts on it. If you do download it, and find suggestions / bugs, please let me know! Cheers https://rm2000.app June 17, 2025 at 08:20PM

Show HN: AI Debate Arena – See Which LLM Argues Best https://ift.tt/xvpG7bO

Show HN: AI Debate Arena – See Which LLM Argues Best Ever wish you could get the best arguments for both sides of a debate? I built an AI-powered debate platform that pits language models against each other on controversial topics. Each AI is randomly assigned a side (pro/con). You vote before and after to see if you were persuaded. Most content today presents lopsided arguments. They provide strong points for one side, weak ones for the other. This project aims to surface the strongest arguments from both sides, using LLMs to simulate a fair debate. With enough usage, I want to use it to benchmark LLMs. My hypothesis is that randomly assigning sides of the debate, models with built-in biases will score worse. It’s currently using GPT 4o, Grok 3, and Gemini 2.5 Flash. It’s early, still rough around the edges, and I’d love feedback on the concept and direction. Curious how the HN crowd thinks this could evolve. It’s built for the intellectually curious that are open minded about changing their positions. Some next steps I’m considering: - Tuning the length and structure of arguments - Prompting improvements to reduce rhetorical fluff - Optional audio output of debates Try it out and let me know what you think! https://ift.tt/fCKS1Ei June 19, 2025 at 12:26AM

Show HN: I built a FOSS tool to run your Steam games in the Cloud I wanted to play my Steam games but my aging PC couldn’t keep up, so I built Cloudy Pad - a tool to run Steam in the Cloud (GitHub: https://ift.tt/36M5EYs ) It runs on AWS, Azure, GCP, Scaleway and Paperspace with various cost optimizations and safeties: - Cost alerts - Auto stop inactive instances to avoid unwanted cost - Disk snapshots and data cleanup for cost efficiency - Spot instance support Under the hood: a Linux VM and a container running Sunshine (a streaming server https://ift.tt/hoaEOWc ) with Steam. Most Windows games work just fine thanks to Proton. It streams effortlessly at 1080p 100+ FPS - I recently played Baldur’s Gate III and Clair Obscur in Ultra, ran like a breeze. Cost-wise it’s great for occasional players: ~30h or less per month typically cost less than 25$. Though admittedly for heavy gamers it may be less cost-effective due to cloud pricing. I’d love feedback from the HN community ! https://ift.tt/36M5EYs June 17, 2025 at 10:57PM

Show HN: Personalized Wealth Management – Institutional Meets Consumer https://ift.tt/tMKu9fv

Show HN: Personalized Wealth Management – Institutional Meets Consumer Problem: If you have less than $100k to invest, you get a robo-advisor that asks you 5 questions and dumps you into one of three cookie-cutter portfolios. If you have more than $100k, you get a human advisor who charges 1-1.5% annually to... basically do the same thing with a smile and calming voice attached. Meanwhile, institutional investors get custom strategies built around specific durations, target dates, tax situations and actual investment goals. Not because the math is harder—but because the economics only work at scale. Here's the thing: Both traditional advisors and robo-advisors maximize profit by minimizing choice and directing capital into the bias strategies that generate them additional margins. Both just tweak a risk slider and call it "personalization." But institutional-grade portfolio construction doesn't have to be exclusive to the wealthy. The road was paved by platforms like Plaid, brining API connectivity—platforms and asset aggregation into the mainstream. Modern AI completes the picture by making true personalization economically viable via "micro-advise". No asset transfers, no new custodians, just sophisticated strategies based on your financial goals executed where you already invest coupled with personalized financial planning & budgeting. Technical Solution: We've built our MVP wealth management platform that creates truly personalized portfolios by combining institutional capital market expectations stemming 30+ global asset classes. All available through low-fee publicly available ETFs. Our approach: - SEC licensed & compliant Registered Investment Advisor - Generates unlimited unique portfolio combinations optimized for risk, return & goal specifics. - Personalizes to individual goals, not generic risk buckets. - Learns and improves from every user interaction - Provides institutional-grade sophistication without human bottlenecks - Removes manager bias for in-house strategies - Uses a "glidepath" approach similar to the US retirement target-date structure to maximize achievement certainty of important life goals (down-payment, retirement, etc) - Seeks to bring elements of habit forming platforms (like Duolingo) into retail wealth. Business Model Innovation: -Non-custodial + AI architecture enables subscription pricing ($10/month) instead of AUM fees. Users keep control of assets while getting personalized institutional strategies. Research Validation: - Glidepath strategies delivered higher values in 76% of scenarios (T. Rowe Price) - Global diversification outperformed domestic-only in 96% of 3-year periods (Hübner) - Chance of success metrics for significant life goals like retirement & major milestones are measurably improved via behavioral advantages & sequence risk protection (T. Rowe Price). Early Results: -Alpha users report 90%+ cost reduction vs. traditional platforms with superior personalization. Institutional style portfolios achieving goal-specific optimization that would cost minimum 10x elsewhere. -Base model portfolios have outperformed comparable portfolios from existing market incumbent robo-platforms on both an absolute & risk adjusted basis in H1 2025. What's Different: This isn't another robo-advisor using basic mean reversion. It's personalization that helps you understands and discover your specific goals and adapts continuously. Think "personal wealth manager in your pocket" rather than "generic portfolio assignment." All that, in a consumer product platform designed to empower retail investors and keep them engaged. Next Steps: Currently in invite-only alpha at www.fulfilledwealth.co. We focused early on the portfolio construction & delivery process and are now building out the consumer-facing aspects of the web application. Looking for feedback from the HN community on our approaches to financial personalization. https://ift.tt/WtEmMT7 June 16, 2025 at 02:58AM

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features https://ift.tt/Oa41Jck

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features Hi hackers! I'm a self-taught solo teenage dev working on Seastar, a unified build system and dependency manager for C and C++. It is capable of compiling and linking projects, managing recursive dependencies and headers, and even has a template system -- your C++ library is one `seastar new mylib --lang c++ --lib` away! Also, everything is configured in TOML, because TOML is awesome. *But why?* C is one of my favorite languages, but I usually end up writing stuff in Rust because I love Cargo. Unlike C, Cargo handles the dependencies, linking, globbing, and so much more for you. So I wrote Seastar to give that function in C and C++. *What's planned?* A package registry like crates.io, compatibility with CMake projects, commands to migrate, and so much more. If you have more ideas, please give them! I am trying to reach 150 stars by the end of summer, and thus a star would be greatly appreciated! This project is still in development, and a star helps out a ton. https://ift.tt/q8fVwcU June 15, 2025 at 11:36PM

Show HN: Gem and I built an open-source app to learn Japanese https://ift.tt/npfC2Aq

Show HN: Gem and I built an open-source app to learn Japanese I've been fascinated by the Japanese language and culture for a while now, and I wanted to create a simple, no-fuss way for beginners to get started. So, I built *[Nihongo]( https://nihongo.site/ )*, a free and open-source web app designed to help you learn the fundamentals of Japanese in about a month. The name of the app, Nihongo (日本語), is the Japanese word for the "Japanese language." You can check it out here: *[ https://nihongo.site/ ]( https://nihongo.site/ )* And for those who like to tinker, the code is available on GitHub: *[ https://ift.tt/lOgkSqB ]( https://ift.tt/lOgkSqB )* The "learn in 30 days" idea isn't about achieving fluency in a month, which we all know is impossible. Instead, the goal is to provide a structured and manageable learning path that covers the essential building blocks of the language in a short period. I wanted to create something that feels less intimidating than many comprehensive (and often expensive) resources out there. *What the app covers:* The app is structured into a series of lessons that you can follow at your own pace. It starts with the absolute basics and gradually introduces more complex concepts: * *The Japanese Writing Systems:* Detailed lessons on Hiragana and Katakana, the two phonetic scripts that are the foundation of written Japanese. * *Essential Grammar:* I've focused on the core grammatical structures you need to start forming your own sentences. * *Core Vocabulary:* You'll learn a curated list of high-frequency words that are immediately useful in everyday conversation. * *Practical Phrases:* The app includes common greetings and phrases that you can start using right away. *Why I built this:* I started building this project while testing the latest Gemini 2.5 models on Google AI Studio, and with the Code assistant and Cloud Run I was able to get it to production in less than 3 hours. This as a personal project to solidify my own understanding of Japanese and to build something useful for others who are just starting their learning journey. I'm a big believer in the power of open-source and wanted to create a resource that is accessible to everyone. This is very much a passion project, and I'm still actively working on it. I'd love to get your feedback, suggestions, and of course, any contributions on GitHub are more than welcome. Let me know what you think! I'm here to answer any questions you might have. https://nihongo.site June 14, 2025 at 03:04AM

Show HN: I rebuilt the recruitment process from the ground up https://ift.tt/y2qcX1D

Show HN: I rebuilt the recruitment process from the ground up Hi HN Community, Recruitment software is everywhere. The market seems saturated. Every other day there’s a new ATS or “all-in-one” platform promising to fix hiring. But let’s be real — recruiting still sucks. Why? Because most tools are just reskinned versions of the same broken process: resume parsing, email campaigns, messy workflows, and outdated data. Some throw in a ChatGPT prompt here and there and call it “AI-powered.” But if we’re still stuck in the same flawed flow, it doesn't matter how modern the UI is. I’ve felt this pain personally — both as a recruiter and a job seeker. That's why I built Chronoflow — not just another ATS, but a reimagined recruitment system that actually works. --What makes it different: No resume parsing. No data entry. Candidate pools build themselves as soon as someone accepts your job invite. --No email campaigns. You already have the latest candidate data, and the platform shows you exactly who to engage. --No endless back-and-forth. Job invites include everything — replacing pre-screening calls and endless follow-ups. --Candidates get live updates and AI-generated feedback if rejected — improving their experience and keeping your brand strong. --Recruiters focus on decision making and building relationships, which is important for business development. Chronoflow is built for people who are tired of trying “yet another ATS” that solves 10% of the problem. If you're curious to see what a rebuilt hiring cycle looks like that drastically reduces time to hire and on top of that makes recruitment transparent and enjoyable, I'd love for you to give Chronoflow a try. Happy to answer any questions. And if you've worked in recruiting, would love to hear what frustrates you most — maybe I can solve that too. Thank You https://chronoflow.ai/ June 12, 2025 at 11:04PM

Show HN: AuraCoder – Gen AI Learning Platform https://ift.tt/4JEPvSa

Show HN: AuraCoder – Gen AI Learning Platform Hey HN, I've been pouring my time into this side project and I think I finally got an MVP up! I'm really excited about it. I'm really passionate about combining LLMs and learning. It seems like one of the best firsts for the tech. And so I built a site where all the content is generated. As I've been building, I'm always torn between building something more general purpose where you can learn anything vs building something targeted where the generation can be more tailored. Currently, its the latter so the site is focused on data structures and algorithms. That's something I've ground out recently so just familiar with what good content might look like and it was helpful in getting the prompt engineering to generate decent content. The site can generate both Lessons and Challenges. And they are a bit tailored to you. You can set settings about what kind of preferences you have. Tone of voice, depth, even an open text that gets feed into the prompt. I tried "Include a cat joke in every lesson" and I thought that was pretty entertaining It also takes into account your current skill level on different concepts. But I also think I need to lean in more on the customization. That seems to be the biggest way AI generated content can differentiate. I think its been hard to generate content that's really as good as human expert generated stuff, but it can be tailored to the user. So really interested in ideas in that vein. And in general, any advice is greatly welcomed. Also of course willing to AMA. Happy to answer any questions about the tech stack, the apps architecture, etc Sorry the site requires sign-up. I've thought about allowing anonymous users, but haven't implemented that yet. However, the site is free, and I'm not even doing any kind of email verification. So I won't judge you if you go with "some-fake-email@example.com" Hope your day is going well and all the best! https://auracoder.com/ June 12, 2025 at 06:01AM

We decided to launch our "course" as an MCP server. This way your coding agent actually teaches the course content to you and can help you write the code. We think this is a really interactive way to learn. Using an editor with MCP support (such as Cursor, Windsurf, or VSCode), your code agent will call the appropriate MCP tools which will return context for the agent. This context tries to instruct the agent that it should be teaching you the content, not just doing the work for you. The course is still pretty experimental and some models work better than others. Code is available in the Mastra Github repo in the mcp-docs-server package ( https://ift.tt/Dh4yZwQ... ) https://ift.tt/C8BIR17 June 11, 2025 at 12:36AM

Show HN: An open-source rhythm dungeon crawler in 16 x 9 pixels I just released my latest Godot project, a rhythm-based dungeon crawler a la Crypt of the Necrodancer. The entire game plays out in 16 x 9 pixels because of a dare from my game dev group. I've open-sourced (MIT) the code and project files. Of course, the music files I don't own aren't included in the Github project, but I'm releasing the game's hand-crafted pixel sprites under CC0. The Github page also talks about some of the tricks you need to make the rhythm part of the game play nice with the dungeon crawling part. https://ift.tt/tJQul5i June 6, 2025 at 02:20PM

Show HN: RenderDay: A GPU-only render farm for Blender https://ift.tt/hkf24Dr

Show HN: RenderDay: A GPU-only render farm for Blender Hey HN! I recently had to render my first longer Blender animation, and I found myself pretty frustrated with the existing render farms out there. Everything I tried was either buggy, overly complicated (I really don’t want to pick from a huge list of hardware options), or just *really* expensive. So, I did what anyone would do.. I built my own solution: https://renderday.com - a GPU-only render farm for Blender that’s super fast and dead simple to use. You just: 1. Upload your `.blend` file 2. Pick your settings 3. Get a price, pay, and render - done No subscriptions, no upfront costs, no contracts - just pay as you go. I pull in daily GPU prices from multiple providers (with a tiny margin to keep the lights on), so the pricing is transparent and competitive. Under the hood it's running on NVIDIA L40S GPUs (48GB RAM), with access to over 1,000 GPUs globally. Currently supports: * Blender 4.3 and 4.4 (can add more if needed) * Cycles and EEVEE * Real-time progress tracking with live preview frames * Full file encryption, auto-deletion after 30 days, no access/sharing --- But more importantly: I'd really appreciate your feedback. This started as a personal itch, but I want to build something genuinely useful for the Blender community - especially indie creators and small studios who can't afford big monthly plans or don't want to deal with complicated setup. - What do you wish render farms did better? - What features are missing for you right now? - Would you use something like this - and if not, why not? Would love to hear your thoughts - good or bad - so I can keep improving it. Thanks for reading! Sascha https://renderday.com June 10, 2025 at 12:54AM

Show HN: SelfDB – Ditch Supabase and Firebase Lock-In, Self-Host Simply https://ift.tt/puyCQat

Show HN: SelfDB – Ditch Supabase and Firebase Lock-In, Self-Host Simply Hey HN! We're a small team of developers who, like many of you, love the power and convenience of Backend-as-a-Service (BaaS) platforms. However, we've also felt the sting of vendor lock-in, wrestled with the complexities of self-hosting feature-rich open-source alternatives, and worried about unpredictable costs or the sudden disappearance of free tiers that many indie devs and small projects rely on. We believe developers deserve more control and simplicity without sacrificing functionality. After countless hours spent navigating these challenges, we decided to build the solution we wished existed. So, we built SelfDB: a self-hosted, open-source alternative to platforms like Supabase or Firebase. SelfDB provides a PostgreSQL database, secure JWT-based authentication (with anonymous access capabilities), integrated object storage, WebSocket-based real-time updates, and serverless cloud functions powered by Deno 2.0 – all packaged into a single, easy-to-deploy containerized platform. Our goal is to give you the comprehensive features you expect from a modern BaaS, but with the freedom and control that comes from truly owning your backend stack. Here’s what SelfDB offers: Full PostgreSQL Power: Your data, your schema, no compromises. Direct SQL access when you need it. Robust Authentication: Secure user management with JWT tokens and flexible anonymous access. Integrated Object Storage: A dedicated SelfDB Storage Service for your files and media. Real-time Updates: Keep your applications in sync effortlessly using WebSockets. Modern Cloud Functions: Write custom serverless logic with Deno 2.0, benefiting from its security-first approach and native TypeScript support. Dead-Simple Deployment: This is where we really focused. Forget wrestling with a dozen different containers for a self-hosted BaaS. With SelfDB, you just need to unzip , configure your .env file, and run ./start.sh. That’s it. Truly Open & Yours: Your SelfDB purchase includes full access to our source code, empowering you to redeploy the software as often as you need. While resale is not permitted, you have the freedom to modify the code to perfectly fit your requirements. Your purchase also grants you access to our exclusive customer portal. Here, you'll receive continuous, free updates and can connect with the vibrant SelfDB community to network, report bugs, and provide valuable feedback. Production-Ready: We've architected SelfDB with security, logging, and monitoring considerations from the outset, so you can build with confidence. Under the hood, SelfDB leverages a FastAPI backend, known for its high performance and developer-friendly features , ensuring a responsive API. The cloud functions run in a Deno 2.0 environment, offering a modern and secure way to extend your backend. The entire platform is containerized using Docker and Docker Compose, with persistent data managed through Docker named volumes. You can get up and running locally with just a few commands: Full details, including the architecture diagram, are in zip you get when you buy Selfdb. To celebrate our launch and thank the early adopters in the HN community, we're offering. This is a great way to try out the extended features while supporting the project. You can find more details and grab the offer at : https://selfdb.io We're incredibly excited to share SelfDB with you today! SelfDB is new, and your feedback is invaluable to us. What are your biggest BaaS pain points? What features would you love to see in a self-hosted platform like SelfDB?

Show HN: AStack – A composable framework for building AI applications AStack is a composable framework designed to simplify the development of AI applications through a "everything is a component" philosophy. It provides a zero-adaptation layer design that enables seamless integration between various AI models, tools, and custom business logic. AStack is an independent technical framework with its own architecture and ecosystem, built on top of Hlang - a highly semantic fourth-generation language (4GL) inspired by Flow-Based Programming paradigms. This foundation on Hlang, which is particularly well-suited for computational modeling and AI-generated code, is what gives AStack its power. The framework emphasizes minimalism and performance, allowing developers to create complex systems with minimal boilerplate code while maintaining complete technical autonomy. https://astack.tech https://ift.tt/VnaUIp7 June 8, 2025 at 07:21AM

Show HN: AI that extracts brand identity from websites to generate ads https://ift.tt/iqgKaoR

Show HN: AI that extracts brand identity from websites to generate ads I built this because I kept procrastinating on creating ads for my projects. The technical challenge was interesting: how do you teach AI to extract "brand identity" from a website? Turns out websites are messy. Finding the actual logo vs random images, identifying brand colors vs generic link colors, understanding brand voice from homepage copy. The solution: Custom vision models + CSS parsing + GPT-4 for voice analysis. You paste a URL, it extracts brand elements, generates platform-specific ads. Not trying to "disrupt advertising" or anything dramatic. Just solving the specific problem of "I need a Facebook ad but Canva makes me want to cry." Built with Next.js, custom image processing pipeline, OpenAI API. The brand extraction accuracy is around 85% for well-structured sites, lower for sites that are... creative with their CSS. Happy to discuss the technical approach or share code snippets if anyone's curious about the brand extraction pipeline. https://board.ad https://www.board.ad June 8, 2025 at 09:15AM

Show HN: String Flux – Simplify everyday string transformations for developers https://ift.tt/32WGAYD

Show HN: String Flux – Simplify everyday string transformations for developers I built https://stringflux.io/ to make everyday string transformations a little less painful. It’s similar to CyberChef in the sense that it supports multiple string operations, but with a cleaner, more focused UI and smart suggestions based on your input. You can also chain transformations — for example: decode base64 string which was base64 encoded from minified json → then json format (pretty-print) it — all in one flow. This is helpful when dealing with complex or nested strings, like encoded API responses or log data, where you need to apply multiple steps to make the content readable. The idea came from the frustration of jumping between different tools just to handle common string tasks. There’s a short GIF demo in the GitHub README: https://ift.tt/b7Bj2uR Would love to hear your thoughts and feedback! https://stringflux.io June 6, 2025 at 02:05AM

Show HN: Create LLM graders and run evals in JavaScript with one file https://ift.tt/5NjlOdn

Show HN: Create LLM graders and run evals in JavaScript with one file Hi HN! Run it: OPENROUTER_API_KEY="sk" npx bff-eval --demo We built a tool to help people take LLM outputs and easily grade them / eval them to know how good an assistant response is. We've built a number of LLM apps, and while we could ship decent tech demos, we were disappointed with how they'd perform over time. We worked with a few companies who had the same problem, and found out scientifically building prompts and evals is far from a solved problem... writing these things feels more like directing a play than coding. Inspired by Anthropic's constitutional ai concepts, and amazing software like DSPy, we're setting out to make fine tuning prompts, not models, the default approach to improving quality using actual metrics and structured debugging techniques. Our approach is pretty simple: you feed it a JSONL file with inputs and outputs, pick the models you want to test against (via OpenRouter), and then use an LLM-as-grader file in JS that figures out how well your outputs match the original queries. If you're starting from scratch, we've found TDD is a great approach to prompt creation... start by asking an LLM to generate synthetic data, then you be the first judge creating scores, then create a grader and continue to refine it till its scores match your ground truth scores. If you’re building LLM apps and care about reliability, I hope this will be useful! Would love any feedback. The team and I are lurking here all day and happy to chat. Or hit me up directly on Whatsapp: +1 (646) 670-1291 We have a lot bigger plans long-term, but we wanted to start with this simple (and hopefully useful!) tool.

Show HN: Smart Palette – Reimagining AI Art https://ift.tt/G6JlmW4

Show HN: Smart Palette – Reimagining AI Art Hi HN, I'm Nick. Over the last 6 months I’ve been building Smart Palette – a platform to help anyone create unique, wall-ready art without needing to be a prompt expert. I started this because I wanted to unleash creativity in anyone and help them bring their art ideas onto their wall through a simple, guided and inspiring process. Instead of figuring out the “right” words to use, you just select your interior design style, room, art style, theme, and color palette. You can simply describe what you want to see and add your desired colors — or let Smart Palette handle it for you. Smart Palette uses a streamlined UI that my backend then translates into optimized, detailed prompts. A lot of the work went into this "translation" layer to ensure optimal model selection, settings and generation techniques depending on the user’s creative context. It also has a full print-on-demand (UHD) integration including various cusotmization options and an art preview feature. This is an early version, and I'd be very grateful for any feedback you have on the concept, the UX, or any technical aspects. Happy to answer any questions! You can try it out with a free trial and generate your first artwork. Here’s a quick walkthrough: https://ift.tt/QwyTfP7?... https://ift.tt/dpViZq3 June 4, 2025 at 11:28PM

Show HN: Page Magic: Use AI to customize any web page I built this Chrome extension (using Claude Code) to help me customize the style of web pages to my liking. It's not perfect, but it does a decent job most of the time. You will need to bring your own Anthropic API key and add it in the settings if you want to try it out. Features: - Use natural language to customize any web page - You can make the changes apply to the current page only or domain-wide - You can see your prompt history for the page and toggle any of them - Cost is tracked using Anthropic pricing and token counts (it may not be 100% accurate, but close enough) Cost per change tends to be around $0.005 depending on page size. Things you can try: - Change the background color, text color, etc. - Remove obnoxiously large hero images - Reduce line spacing - Increase content area width - Remove stickiness of top headers - ... anything you can think up https://ift.tt/IXGxuiK June 3, 2025 at 04:24AM

Show HN: I build one absurd web project every month I’ve been building absurd, mostly useless web projects for fun — and I publish one every month at absurd.website. These are deliberately non-functional, weird, sometimes funny, sometimes philosophical — and usually totally unnecessary. Some examples: Sexy Math — solve math problems to reveal erotic images. Trip to Mars — a real-time simulation that takes 7 months to finish. Add Luck to Your e-Store — add a waving cat widget to boost your conversion via superstition. Microtasks for Meatbags — the future: AI gives prompts, humans execute. Invisible Lingerie — it’s sexy. And invisible. Artist Death Tracker — art prices spike when artists die. We track that. Open Celebrity — one open-source face, shared by all. Together we make her famous. I just enjoy exploring what the web can be when it doesn’t try to be “useful”. Would love to hear what you think — and absurd ideas are always welcome. https://absurd.website June 2, 2025 at 11:52PM

Show HN: GoogLLM – Google search that returns Markdown instead of HTML https://ift.tt/DiYRdp0

Show HN: GoogLLM – Google search that returns Markdown instead of HTML As part of my bigger goal to make the web more agent-friendly, this weekend i decided to tackle google. The "AI-native" search APIs like Tavily and Exa exist, but they require setup and don't actually use Google's results. So I built something simple - a proxy that takes Google search URLs and returns the results as clean markdown instead of HTML. You literally just change "google.com" to "googllm.com" in any search URL. ```bash # Returns 500KB of HTML: curl " https://ift.tt/LUFtbH4 " # Returns clean markdown: curl " https://ift.tt/rNu7s5z " ``` *What it does:* - Serves normal HTML to browsers (so humans can use it normally) - Returns markdown to everything else (curl, fetch, LLM agents) - Supports all Google search types: web, images, news, scholar, shopping, etc. - No auth needed for testing (10 requests/hour free) *Technical approach:* - Content negotiation based on Accept headers - Caches results to avoid hammering Google - Simple pricing: 0.5¢ per search after free tier I built this over a long weekend because I was tired of writing HTML parsers for every project. The whole thing is designed around a single principle: make Google search results consumable by LLMs without any complexity. *Questions for HN:* - Is this approach too simplistic? Should search APIs be more complex? - How do you currently handle search in your LLM applications? - Any concerns about the proxy approach vs. building from scratch? The llms.txt documentation is intentionally comprehensive (2500 tokens) so any LLM can understand and use it immediately. Live demo: https://googllm.com API docs: https://ift.tt/1enudfl Would love feedback on the approach and any edge cases I might have missed. https://googllm.com June 2, 2025 at 11:07PM

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard ) (All the sources on github under an open source license :D) PS.

Show HN: I'm starting a social club to solve the male loneliness epidemic https://ift.tt/LhQPOr8

Show HN: I'm starting a social club to solve the male loneliness epidemic The other day I saw a post here on HN that featured a NYT article called "Where Have All My Deep Male Friendships Gone?" ( https://ift.tt/pE09RNH ) and it definitely hit home. As a guy in my early 30s, it made me realize how I've let many of my most meaningful friendships fade. I have a good group of friends - and my wife - but it doesn't feel like when I was in college and hung out with a crew of 10+ people on a weekly basis. So, I decided to do something about it. I’ve launched wave3.social - a platform to help guys build in-person social circles with actual depth. Think parlor.social or timeleft for guys: curated events and meaningful connections for men who don’t want their friendships to atrophy post-college. It started as a Boston-based idea (where I live), but I built it with flexibility in mind so it could scale to other cities if there’s interest. It’s intentionally not on Meetup or Facebook - I wanted something that feels more intentional, with a better UX and less noise. Right now, I'm in the “see if this resonates with anyone” stage. If this sounds interesting to you and you're in Boston or another city where this type of thing might be needed, drop a comment or shot me an email. I'd love to hear any feedback on the site and ideas on how we can fix the male loneliness epidemic in the work-from-home era. https://wave3.social May 30, 2025 at 03:57AM

Show HN: Clean Simple DNS Lookups https://ift.tt/9GcT2EU

Show HN: Clean Simple DNS Lookups Hey HN, Last weekend I vibe-coded a cool website that lets you do easy DNS record lookups. I know you can just use dig or nslookup, but oftentimes I'm too lazy to remember the syntax, and there are less technical users who need to manage DNS entries but aren't comfortable with the command line. We debug customer DNS issues often at ImprovMX, and we typically link to tools like mxtoolbox.com to point out DNS record issues. But those tools seem quite bloated and from the 2000s. I wanted something super clean & simple, and there were a few features I thought were ergonomically needed but lacking: - no confusing dropdowns or syntax for DNS lookup, just put in your domain or subdomain - click-to-copy for all values - header-links so we can provide URLs that will direct another user to an exact domain and which record we want to reference This was SUPER FUN to vibe code! The frontend was pretty much one-shotted with lovable. It's amazing how good AI is when working on a clean slate with all the latest popular frameworks (react, tailwind, shadcn, etc.). And I spent the next few hours making small tweaks with cursor. The backend is a dead simple python flask server. Both are hosted on render.com <3 I love how simple and value-oriented render.com is. It's always the provider that gives me the least headache when I want to just launch and forget something.

Show HN: Willow Voice (YC X25) – Personalized Dictation You Can Use Anywhere https://ift.tt/59KAV4H

Show HN: Willow Voice (YC X25) – Personalized Dictation You Can Use Anywhere Hi HN, we're Lawrence and Allan, and we're building Willow Voice, a voice dictation tool for people who type a lot and want to move faster. We started out building for healthcare—first assisted living, then SNFs, then outpatient clinics—but the idea that stuck wasn’t the vertical. It was voice. We watched elderly patients use dictation to stay connected, and doctors reclaim hours with AI scribes. That’s when we realized dictation shouldn’t be limited to healthcare. If it were fast, accurate, and personal enough, everyone could benefit. Willow is not basic speech-to-text. It runs in the cloud for low-latency, supports technical terms and custom dictionaries, and learns your formatting and syntax preferences over time. Our users say it feels like it “just works,” even if they’ve never used dictation before. Some things we’ve already built: 1. Real-time dictation with extremely fast output 2. Context-aware text generation 3. Automatic formatting and structure detection Privacy is our absolute top priority - we do not store or retain voice data by default. Here are a few simple demos: 1. https://youtu.be/yFxH5HY-72Y?si=krI9WNFKBQE1Hvph 2. https://youtu.be/l2zlECbQQcU?si=fJLX-oYrflOI02kj 3. https://youtu.be/yKTIVCZbwHY?si=ohRMpuAUS8eqceAQ We’d love feedback from the HN community, technical questions, product ideas, and more!

Show HN: Image-to-Image Translation Model https://ift.tt/HsD2M3j

Show HN: Image-to-Image Translation Model We launched a v1 of a image to image translation API which translates the text on an images by replacing the existing text. For v1, it's pretty much a model pipeline: OCR current text -> generate mask -> erase text -> translate text -> use embedding comparison to find similar font -> map text back on image v1 was more like a prototype which already beats many of the similar services provided by Google, Azure, etc We're working on v2 where we're training a diffusion model to translate the text on the image. We've got the pipeline working for English and Chinese, and now we're building datasets for other languages. https://ift.tt/ua74z6K May 29, 2025 at 03:47AM

Show HN: I built an AI tool that generates click-worthy YouTube thumbnails https://ift.tt/rH0Sx4f

Show HN: I built an AI tool that generates click-worthy YouTube thumbnails Hey HN! Software engineer here. As an amateur youtuber, I've been struggling with thumbnails, especially since I don't have any design or editing skills. Decided to give it a try and make my own automatic thumbnail generator. Me being an ADHD person, made sure that there's no parameter tuning and shape choosing and fuss like that, just simply give prompt and generate thumbnail. Increased my CTR from 1.2% to 2.3% (faceless fantasy books niche on youtube) Thumbnail X (completely free for now) - https://thumbnailx.com/ Just wanna add that this is by no means a perfect thumbnail maker for huge YouTube moguls with millions of subscribers but I'm sure it's gonna be extremely helpful for beginner youtubers and medium size channels struggling with thumbnails. Tools used: 1. Cursor for development (shoutout to claude oppus 4.0) 2. Few image generators (primarily ideogram, but leonardo ai, deep ai and gpt 4o as fallbacks) 3. Few llms (chatgpt, claude, gemini for validating images and prompt enhancement) 4. AWS and Redis for storage & caching 5. Digital ocean for hosting and db 6.

Show HN: Simulating Bigtable in BigQuery as a Type 2 SCD (100k+ mutations/sec) https://ift.tt/GMbnXoC

Show HN: Simulating Bigtable in BigQuery as a Type 2 SCD (100k+ mutations/sec) I hit a wall recently where we needed to design a data store that can both (1) ingest schema-less updates at scale and (2) allow for large analytical queries. GCP native doesn't have something that does both of these out-of-the-box, so we kinda hacked our own solution by replicating updates from Bigtable into a Type 2 SCD table in BigQuery. i couldn't find many resources online on this sort of trick when I was building it out, so I wrote up this blog with the details. Hope it's helpful and curious if anyone has used or built something similar. Will stick around for comments, happy to answer any questions or feedback. https://ift.tt/XJyYm3r May 28, 2025 at 12:58AM

Show HN: Maestro – A Framework to Orchestrate and Ground Competing AI Models https://ift.tt/VdaEjwL

Show HN: Maestro – A Framework to Orchestrate and Ground Competing AI Models ive spent the past few months designing a framework for orchestrating multiple large language models in parallel — not to choose the “best,” but to let them argue, mix their outputs, and preserve dissent structurally. It’s called Maestro heres the whitepaper https://ift.tt/4KlTC8L (Narrative version here: https://ift.tt/31BWQdM... ) Core ideas: Prompts are dispatched to multiple LLMs (e.g., GPT-4, Claude, open-source models) The system compares their outputs and synthesizes them It never resolves into a single voice — it ends with a 66% rule: 2 votes for a primary output, 1 dissent preserved Human critics and analog verifiers can be triggered for physical-world confirmation (when claims demand grounding) The feedback loop learns not only from right/wrong outputs, but from what kind of disagreements lead to deeper truth Maestro isn’t a product or API — it’s a proposal for an open, civic layer of synthetic intelligence. It’s designed for epistemic integrity and resistance to centralized control. Would love thoughts, critiques, or collaborators. May 27, 2025 at 10:51PM

Show HN: JSON Commenter, add comments with valid JSON syntax JSON Commenter is a vscode extension that lets you create inline comments in a JSON file while keeping valid syntax. You create a block with a command that places the comment anywhere legal in the JSON. The text is edited inline and supports word wrap, padding, margins, etc. The comment is in a somewhat good-looking box with minimal extra characters. Zero-width unicode chars give keys that only show two quotes. This is a sample comment block... " ":"----------------------", " ":" This is a comment.

Show HN: CodeNow – CoderPad over WebRTC and WASM I was doing a lot of Leetcode this winter, and got the idea of building something like it that used wasm in the browser rather than having to manage the complexity of executing remote code securely on a server. Once I figured that out, I thought it would be neat to make it collaborative, like Coderpad — that part was a bit tougher, but it mostly works now, using WebRTC.

Show HN: Tincture – A Color-Matching Puzzle Game I Vibe-Coded with AI in 4 Hours https://ift.tt/XBYPegG

Show HN: Tincture – A Color-Matching Puzzle Game I Vibe-Coded with AI in 4 Hours Hi, Eight years ago, I had an idea for a color-matching puzzle game. I taught myself Swift and Xcode, spent months building an MVP… and then abandoned it. Last week, I decided to revisit the concept to see how far AI coding tools have come. So I played around with an assistant, and vibe-coded a playable version in about 4 hours. It’s called Tincture. It’s a calm, minimalist puzzle game. There are no timers, or ads, just a grid of colors and some simple rules that prioritize efficiency and pattern retention. What began as a random thought, turned into something that’s actually pretty satisfying to play. Turns out you can use math (modular arithmetic) to optimize the solution of the basic mechanics, so I added some complexity in later levels. I followed what felt fun and used a free AI-powered IDE to reach an MVP that would've taken me MUCH longer to dust off my Swift version or start from scratch learning JavaScript. I’d love your thoughts: • Is the core mechanic intuitive? • Did it hit a “this is kinda fun” moment? • Is it worth polishing further, or should it stay a weird little side project? Thanks for taking a look! https://ift.tt/A3DUlVR May 26, 2025 at 12:56AM

I decided to build a better alternative - It's a configurable space for you to hang out online while you work, with a ton of relaxing music and backgrounds. Its got useful tools built in like a timer to keep track of how long you've been locked in, and a notepad for todos or scribbling down ideas while you work.

Show HN: 1min Workouts for People Who Sit All Day https://ift.tt/k1PlWIH

Show HN: 1min Workouts for People Who Sit All Day I am a software developer and in the last few months after recently becoming a father I was barely finding time for a proper workout. Recently I was reading about new research on Snack Exercises and how beneficial mini workouts of less than 2mins every so often, during the day are to our body. So, I decided to build an iOS App for me and others to help with this. The app generates a list of exercises that I need to tick to complete daily or loose my streak. The algorithm takes into account muscle groups and balancing the exercises to hit most main muscles. I also stayed going through all exercises and adding a couple of alternative exercises in case I don't feel like the recommended exercise. Since I'm not a trainer I commissioned professional exercise posture video guides and animations by an exercise expert which I attached to each exercise. I uploaded the app on the app store for free and no ads. If this is something that interests you, I want to hear how you balance a long day on your desk vs exercise. https://shortreps.com May 25, 2025 at 12:41AM

Show HN: Can AI Help Designers Ideate Better? We Spent 5 Wks Finding Out https://ift.tt/YCM9dz1

Show HN: Can AI Help Designers Ideate Better? We Spent 5 Wks Finding Out We set out to answer a simple but deep question: Can AI actually practically help product designers improve during the discovery and ideation phase of the design process? So we spent 5 weeks running an experiment. We mapped every tool we use for discovery: Mobbin, Dribbble, Pinterest, Twitter, Behance We broke down typical design thinking and brainstorming workflows We reviewed every prototyping or idea-capturing tool we’ve used Then we tried building lightweight AI workflows with various LLM tools and frameworks Result: Yes. Used well, AI can significantly improve design thinking — especially for junior/mid-level designers — by offering faster idea generation, design critiques, and creative merges. Out of that research, we built Moonchild: A discovery-stage design ideation tool that: Generates thoughtful UI concepts from minimal prompts Allows asking design questions and getting structured critique Merges styles, flows, and interaction patterns from multiple directions Outputs great Figma-ready screens and UX flows, fast Try it (private beta): https://moonchild.ai Use code 'hackernews' for early access. Would love feedback — especially from product designers, PMs, and UX folks doing early-stage work. May 24, 2025 at 11:06PM

Show HN: GetStack.dev – Track GitHub open-source trends Hi HN! I’ve been working on getstack.dev[1], a tool to help developers track GitHub open-source trends, tech adoption, and repository stacks — updated weekly. About a month ago, I broke my leg. While stuck on the couch, I figured I’d put the downtime to good use and finally build a side project I’d been thinking about for a while. So I put together an MVP and decided to release it publicly to gather feedback. I have always struggle to grasp how people are adopting technology and what's really hype or under the radar. As tech leader you also often want to know if your tech choices are the right one but it's hard to take a data driven solution. And as open-source lover I always want to know how my favorite projects are built.

Show HN: rtcollector - A modular, RedisTimeSeries-native observability agent https://ift.tt/RMwQT2x

Show HN: rtcollector - A modular, RedisTimeSeries-native observability agent I’m a long-time time series nerd, I’ve worked with InfluxDB, TimescaleDB, ClickHouse, and more, across everything from monitoring fleets to tracking medical devices. But recently, I started exploring RedisTimeSeries again… and I was surprised by how much the Redis Stack has evolved. Between RedisTimeSeries, RedisJSON, RediSearch, and Streams, I realized: this could actually be the backbone for a full observability stack. So I built rtcollector, a modular, Redis-native observability agent. It’s written in Python, configured with YAML, and designed to push system, container, and database metrics into RedisTimeSeries with labels and retention. Think of it as a Telegraf alternative, but for Redis. Right now, I’ve implemented input plugins for: • Linux: CPU, memory, disk, I/O, network • macOS: CPU, memory, disk, I/O, network • Docker: container stats via API • Redis, MySQL, PostgreSQL The idea is to keep it simple, extensible, and Redis-first. Next steps: • Native logs via RedisJSON + RediSearch (already prototyped!) • Support for Redis Streams (for traces/events) • Dashboards in Grafana using the Redis data source If you’re into observability, Redis, or just like building small purposeful tools, I’d love your thoughts or contributions. It’s early, but already useful for homelabs, edge boxes, and anyone tired of deploying 10 containers just to get CPU metrics.

Show HN: Super (YC W18) - Turn company data into answers & agents for your team https://ift.tt/Ic6JDQR

Show HN: Super (YC W18) - Turn company data into answers & agents for your team Hey there, Chris here We're known for our straightforward yet powerful Knowledge Base, Slite(YCW18).We launched our AI-powered search in Feb 2023 and after getting great response and usage, we dove deeper into solving the challenge of knowledge retrieval in daily work. That's why we're now launching our second major product, Super( https://www.super.work ). Super seamlessly connects your existing tools, providing accurate answers, streamlined workflows, automated digests, and much more. You might wonder: Why not just link your apps together using something like an MCP? The problem is that MCPs can't handle complex knowledge retrieval effectively. MCPs are basically LLMs equipped with API toolbelts. If you've ever tried asking a complicated question through an MCP, one that needs data from multiple different tools, you've likely faced frustrating delays. MCPs slowly make API calls one after another, causing long waits while they collect data from each endpoint. By contrast, Super quickly searches through all the data that actually matters from all of your tools simultaneously. This means you'll get your accurate answer in seconds, not minutes. The limitations of MCP-based solutions become clear when you try to deploy them reliably within a team. They either won't index your critical content effectively, won't do it fast enough, or won't cover all your tools at once. Properly chunking, embedding, querying, and filtering data from various sources is still essential. MCPs triggering APIs can't match this integrated approach for speed and accuracy. Moreover, Super understands the value of running multiple tasks simultaneously through LLMs. For example, one step may involve identifying search filters, while another simultaneously uses an LLM to aggregate and refine information. This parallel process quickly shapes the final, accurate answer for users. Additionally, MCPs aren't designed for enterprise-grade use. Businesses need standardized experiences, fine-grained user permissions, and consistent access controls across multiple tools. Super addresses these requirements by indexing data beforehand while still respecting each user's access permissions. Super offers: - Perplexity-like search experience on your team data - A growing selection of integrations with popular data sources - Customizable AI assistants tailored to your specific needs - An extension to embed Super directly into external websites you're already using - A clear path for your company to adopt AI strategically, rather than letting individual employees scatter across different, incompatible tools. And of course... It does comes with its MCP, which makes your agentic workflows actually able to properly tap on your data. Here's a quick video showing Super in action: https://www.youtube.com/watch?v=L5A6BRW90K4 Have you hit such walls with standard MCPs? Have you try building your own solutions? https://super.work May 21, 2025 at 06:18PM

Show HN: A native Hacker News reader with integrated todo/done tracking https://ift.tt/691Yjwz

Show HN: A native Hacker News reader with integrated todo/done tracking Hey HN! I'm excited to share a tool I've been working on - a native Hacker News reader built with Rust and egui. Here's a screenshot: https://ift.tt/yRBpAOs... . As a daily HN reader, I've always struggled with keeping track of interesting posts I want to read later. Browser tabs pile up, bookmarks get forgotten, and I lose track of what I've already read. I needed a way to: 1. Browse HN efficiently (across all sections - hot, new, show, ask, jobs, best) 2. Quickly mark posts as "todo" for later reading 3. Mark posts as "done" when finished 4. Filter and search effectively I couldn't find a tool that combined all these features, so I built one. It's been tremendously helpful for my own HN reading workflow, and I thought others might find it useful too. Features: - *Integrated todo tracking*: Mark stories as "todo" and "done" to manage your reading progress - *Search functionality*: Filter stories by keyword in title, domain, or author - *Multiple sections*: Browse all HN sections (hot, new, show, ask, jobs, best) - *Threaded comments*: View comments in a Reddit-like threaded format - *Dark/light mode*: Easy on the eyes in any environment - *Keyboard shortcuts*: Efficient navigation with keyboard-centric design (1-6 for tabs, Ctrl+F for search) - *Auto-loading*: Automatically loads more content when scrolling - *Color-coding*: Stories color-coded by score for easy scanning - *Native app*: Fast, responsive, and works offline with local caching Built with Rust and the egui UI framework, with SQLite for local storage. The app scrapes Hacker News HTML directly rather than using the official API to capture the full story context. Check out the GitHub repo ( https://ift.tt/jk3Shom ) for installation instructions and source code. Built and tested on macOS, Linux, and Windows. This started as a personal tool to solve my own HN reading habits, but I hope others find it useful too. The code is MIT licensed and I'd love your feedback, feature suggestions, or contributions! https://ift.tt/kHuN1Xf May 19, 2025 at 10:23PM

What you’ll find • One-to-one translation of the paper’s formalism: Substrates, Attributes, Tasks, Constructors, and task-algebra operators • Possibility / impossibility predicates and counterfactuals encoded exactly as defined • Test suite that mirrors every lemma and example (>95 % coverage, mypy-typed) • Reproductions of key results: time-keeping substrates, irreversibility proofs, quantum branching tasks, and a self-replicating constructor Why share? Reading the paper is tough going; expressing each definition in code clarified the ideas and surfaced a couple of questions for discussion. Hoping it helps others and sparks extensions. Looking for feedback: • Did I miss any subtleties in the formalism? • Which additional theorems or examples would you like implemented next?

It’s fully self-funded and will be released commercially on Steam. Engine source code (MIT): https://ift.tt/X0UtJw2 I’d love feedback on the gameplay, visuals, performance, or anything else. Thanks! https://bereprobate.com May 17, 2025 at 01:40AM

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless https://ift.tt/LAnvGyZ

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless Hey everyone! Over the past two years I threw myself back into full-time engineering with a simple goal: write code that gives back to the community. After a lot of late-night FOMO (“AI will do it all for us, right?”) and some painful production incidents, I finally turned my weekend project into an open-source library. [ What is Solidis ? ] - Super-light (< 30 KB) RESP2/RESP3 client with zero runtime deps and first-class ESM/CJS support. - Fully tree-shakable – import only the commands you need. - Written with SOLID principles & full TypeScript typings for every command. - Designed for cold-start sensitive serverless platforms (small bundle + tiny memory footprint). [ Why I built it ] 1. node-redis & ioredis pain - ESM is still an after-thought. - Hidden deadlocks on RST, vague error surfaces. - Everything gets bundled, even commands you’ll never call. 2. I refuse to add a dependency I don’t fully understand – I literally read candidates 10× before `npm i`. 3. Serverless bills love to remind me that every KB and millisecond matters. [ Key features ] - Protocols: RESP2 and RESP3 (auto-negotiation) - Bundle size: `<30 KB` (core) / `<105 KB` (full) - Dependencies: 0 - Extensibility: Drop-in command plugins, custom transactions - Reliability: Auto-reconnect, per-command timeouts, type-checked replies [ Roadmap / Help wanted ] - Benchmarks against `node-redis` & `ioredis` (PRs welcome!) - More first-class Valkey love - Fuzz-testing the parser - Docs site – the README came first; I’d love help polishing full docs This might be my last big OSS push for a while, so stars, issues, and PRs mean the world . If Solidis saves you some cold-start time or just scratches a TypeScript itch, let me know! Repo: https://github.com/vcms-io/solidis License: MIT Thanks for reading, and happy hacking! (Feel free to AMA in the comments – I’m around.) https://github.com/vcms-io/solidis May 17, 2025 at 01:20AM

Show HN: KVSplit – Run 2-3x longer contexts on Apple Silicon https://ift.tt/tFBuSGA

Show HN: KVSplit – Run 2-3x longer contexts on Apple Silicon I discovered that in LLM inference, keys and values in the KV cache have very different quantization sensitivities. Keys need higher precision than values to maintain quality. I patched llama.cpp to enable different bit-widths for keys vs. values on Apple Silicon. The results are surprising: - K8V4 (8-bit keys, 4-bit values): 59% memory reduction with only 0.86% perplexity loss - K4V8 (4-bit keys, 8-bit values): 59% memory reduction but 6.06% perplexity loss - The configurations use the same number of bits, but K8V4 is 7× better for quality This means you can run LLMs with 2-3× longer context on the same Mac. Memory usage scales with sequence length, so savings compound as context grows. Implementation was straightforward: 1. Added --kvq-key and --kvq-val flags to llama.cpp 2. Applied existing quantization logic separately to K and V tensors 3. Validated with perplexity metrics across context lengths 4. Used Metal for acceleration (with -mlong-calls flag to avoid vectorization issues) Benchmarked on an M4 MacBook Pro running TinyLlama with 8K context windows. Compatible with Metal/MPS and optimized for Apple Silicon. GitHub: https://ift.tt/ZukWCdD https://ift.tt/ZukWCdD May 17, 2025 at 12:04AM

Show HN: Easel – Code multiplayer games like singleplayer https://ift.tt/nQdjMas

Show HN: Easel – Code multiplayer games like singleplayer For the past 3 years, I've been creating a new 2D game programming language where the multiplayer is completely automatic. The idea is that someone who doesn't even know what a "remote procedure call" is can make a multiplayer game by just setting `maxHumanPlayers=5` and it "just works". The trick is the whole game simulation, including all the concurrent threads, can be executed deterministically and snapshotted for rollback netcode. Normally when coding multiplayer you have to worry about following "the rules of multiplayer" like avoiding non-determinism, or not modifying entities your client has no authority over, but all that is just way too hard for someone who just wants to get straight into making games. So my idea was that if we put multiplayer into the fabric of the programming language, below all of your code, we can make the entire language multiplayer-safe. In Easel the entire world is hermetically sealed - there is nothing you can do to break multiplayer, which means it suits someone who just wants to make games and not learn all about networking. I've had people make multiplayer games on their first day of coding with Easel because you basically cannot go wrong. There were so many other interesting things that went into this project. It's written in Rust and compiled to WebAssembly because I think that the zero-download nature of the web is a better way of getting many people together into multiplayer games. The networking is done by relaying peer-to-peer connections through Cloudflare Calls, which means Cloudflare collates the messages and reduces the bandwidth requirements for the clients so games can have more players. I also took inspiration from my experience React when creating this language, here's how you would make a ship change color from green to red as it loses health: `with Health { ImageSprite(@ship.svg, color=(Health / MaxHealth).BlendHue(#ff6600, #66ff00)) }` There is a lot of hidden magic that makes the code snippet above work - it creates a async coroutine that loops each time Health sends a signal, and the ImageSprite has an implicit ID assigned by the compiler so it knows which one to update each time around the loop. All of this lets you work at a higher level of abstraction and, in my opinion, make code that is easier to understand. Speaking of async coroutines, my belief is that they don't get used enough in other game engines because their lifetimes are not tied to anything - you have this danger where they can outlive their entities and crash your game. In Easel each async task lives and dies with its entity, which is why we call them behaviors. Clear lifetime semantics makes it safe to use async tasks everywhere in Easel, which is why Easel games often consist of thousands of concurrently-executing behaviors. In my opinion, this untangles your code and makes it easier to understand. That's just the beginning, there is even more to talk about, it has been a long journey these past 3 years, but I will stop there for now! I hope that, even for those people who don't care about the multiplayer capabilities of Easel, they just find it an interesting proposal of how a next-generation game programming language could work. The Editor runs in your web browser and is free to play around with, so I would love to see more people try out making some games! Click the "Try it out" button to open the Sample Project and see if you can change the code to achieve the suggested tasks listed in the README. https://ift.tt/sGIiQLE May 14, 2025 at 02:31PM

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser https://ift.tt/nZxMRg0

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser Randomly got inspired yesterday seeing SmolVLM working on WebGPU and had the silly idea for this project. it's not perfect and super limited because of the current limitations of WebML (and admittedly, because I suck at prompting, but that's why it's Open Source haha) but it is 1.5B WORTH OF AI (SmolVLM 500M and LLama 3.2 1B) working RIGHT IN YOUR BROWSER with you not having to install anything! In fact, the whole thing is actually just an index.html that you can install and even use directly! It might be a little bit slow on first try (takes about 3 mins) when it installs models, but it caches it so it's way faster the second time (also, it's available offline after it's cached haha) Works on any modern web browser It may be a funny little project, but it's genuinely taught me so much about WebML and Vision models, and the technologies we're getting with WebML will 100% democratize AI access and make it way simpler and easier to be used everywhere :p GH Repo in case you're interested: https://ift.tt/cdilwGE https://ift.tt/SI09Nbk May 15, 2025 at 11:20PM

Show HN: Family Folder – Help your family remember everything, organise anything https://ift.tt/bhCFca5

Show HN: Family Folder – Help your family remember everything, organise anything Hi Show HN, I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment. This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between. The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families. Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Coming soon: iOS app & AI assistant) Family Folder is private by design—you only see what you’re invited to. It’s meant to be simple enough for parents or siblings to actually use, but structured enough to avoid chaos. If this sounds useful—or if you’ve ever tried to manage a family using group chats or shared docs—I’d love your feedback. What would make something like this truly work for your family? Thanks for taking a look! – Tony https://ift.tt/z03HW6w https://ift.tt/z03HW6w May 14, 2025 at 10:57PM

Show HN: GS-Base – A multifunctional database tool with Python integration A wide range of possible use: from simple contact/inventory lists, photo albums to editing CSV/text files and processing (transforming, splitting, merging, normalizing) large, multi-GB data tables in various file formats. Text, Numeric, Long Text / Memo fields, Image / File fields; Code fields for code snippets with syntax highlighting for 16 programming languages. You can analyze, query and consolidate data, generate pivot tables, perform calculations, merges and joins with up to 256 million rows, 16K columns and 4GB+ files efficiently using even older PC's. Several filtering methods, searching for duplicates, for unique values and their frequencies, search-as-you-type, random and quartile searches, full-text searches, fuzzy searches. RegEx filtering of millions of records in seconds regardless of the number of the returned found records. Searching for file duplicates, finding similar photos/images, music and video files using any EXIF tags and multimedia (e.g. mp3/mp4) tags. Playing filtered lists of mp3's. Very fast data consolidation - you don't have to bother with permanent indices; internal indexes are created automatically whenever aggregation and binary lookup functions need them. Generating disk/folder listings and monitoring all file changes with searchable history of modifications. Mass-renaming, -copying and -deleting files based on filtered file listings. GS-Base can be installed on any portable storage device and used without performing any registry modifications. Fully offline - doesn't need internet connection. To move it to another computer you can simply copy the installation folder containing a few files. Questions and suggestions are welcome. https://ift.tt/bTpDH3K May 13, 2025 at 01:02AM

Show HN: Open-source AI code review agent that's aware of your entire codebase https://ift.tt/jNmcqe7

Show HN: Open-source AI code review agent that's aware of your entire codebase Hey HN! I'm one of the cofounders of Sourcebot, an open source alternative to Sourcegraph. Sourcebot lets you index thousands of repos across multiple platforms (GitHub, GitLab, Bitbucket), and gives you a powerful interface to search across them. You can learn more in our original HN launch post: https://ift.tt/XQuvKRJ We just added an AI code review agent that reviews your PRs and automatically detects issues that a human reviewer may have missed. We've been using an AI code review agent for a few weeks now, and it regularly catches issues that we would've merged to prod. The review agent automatically fetches relevant context from code you've indexed in Sourcebot to provide accurate reviews. We’ve found that fetching this context is critical for the LLM to provide meaningful suggestions. Would love any feedback if y'all get the chance to try it out! We're planning on expanding the context fetching capabilities to support: - Fetching definitions from function calls in a code snippet - Fetching all usages of a function across all your repos to ensure proper usage patterns - Any other code context fetching y'all think would be useful!
