Show HN: Speech-to-speech playground for OpenAI's new Realtime API https://bit.ly/3BsLRXC

Show HN: Speech-to-speech playground for OpenAI's new Realtime API Hi there - Ben from LiveKit here! If you’re curious about OpenAI’s brand-new Realtime API and speech-to-speech model, check out this hosted playground and play with the model yourself. If you’d like to learn more about how this came together, read on. If you’re like me, you’ve probably been wondering what novel things a model like this can do in an API setting with unfettered access to the system prompt and other parameters. I’ve been fortunate to have had early access through my work at LiveKit, where we’ve built open-source developer tooling that makes deploying this model in a production app as simple as possible. I thought it would also be fun to build a “playground” environment, partially to dogfood our own tooling but largely because I just wanted to play with the model. This playground is freely available to anyone to try, and comes loaded up with a bunch of fun demos of the model’s unique capabilities that I’ve put together. What blew my mind is how much mileage you can get out of the system prompt alone in this API. Here are some use-cases that are at least halfway to a complete MVP: - "Customer Support": An complete phone support agent for the playground - "Spanish Tutor": A bilingual language-learning demo - "Meditation Coach": It can actually pause and resume speech all on its own as it guides you through a meditation routine Also some fun (and a bit irreverent…) demos of its style and non-verbal capabilities: - "Smoker’s Rasp": It can cough and speak like it’s been smoking three packs a day for 30 years (my favorite, lol) - "Unconfident Assistant": Umms, buts, and more - surprisingly lifelike - "Opera Singer": The best singing demo I’ve been able to compose (but still not quite what they showed off back in May…) The playground doesn’t store anything anywhere besides your browser but you can share anything fun you put together with a link that encodes your config into URL params. For now - anyone can use this playground to access the model and give it a spin (session limit 5min). In the coming days when more people have access to the underlying API, I’ll update it to require you bring your own OpenAI API Key. Lastly - if you’re even more curious how this was built or want to tweak or adapt it for yourself, the whole project and every dependency is open-source (link in footer!). https://bit.ly/3XQ25S5 October 2, 2024 at 02:59AM

Show HN: Presidential polling with instant electoral results https://bit.ly/4emeuEz

Show HN: Presidential polling with instant electoral results Hi HN! This is an experiment with low-friction, "fearless", Internet-based polling. There is no authentication, only a captcha and restriction to US IP addresses. Congressional district is detected automatically. Selections can be changed at any time until the poll closes, kind of like a presidential caucus. Just tap to select. Tap again to change. I built this after pondering about how polling (or even voting) could be improved through technology. Yes, digital voting is a tough space with trust issues. Maybe there are practical, partial solutions. This is my third post. Earlier submissions didn't perform well, probably because politics is a sensitive subject. However, this project is not political. It is about tech and process. I believe it's an appropriate submission for HN and it ought to be interesting no matter your political leaning. Hopefully with this better framing there can be better discussion. Another way of looking at it: if the poll results bother you, think about how improving polling/voting generally might help your cause. Here are some topics to guide constructive discussion: * Internet-based polling. Can we make this a routine thing? Would it be worthwhile? Abuse prevention? * Internet-based voting. About time or never gonna happen? * Augmenting the voting experience. We don't have ranked choice voting, but maybe it could be simulated in advance of an election. Maybe an organization could act as a delivery agent for mail-in votes. * The tech stack. This project uses a combination of boring (Django+Postgres) and shiny (Fastly edge pub/sub, captcha, etc). The database ought to be able to handle a few million participants. To get to a few hundred million I'd probably add more PG nodes and shard. Curious what others think about the database options for accurate+fast counting. * Have fun with it! This isn't a real election. If you want to VPN to an empty state to claim a bunch of electoral votes, go for it. I hope with enough participants the results would be mostly representative, though. The poll will run every Monday afternoon/evening until Election Day. It's designed to withstand a good bit of traffic so feel free to share it.

Show HN: Offline macOS app to convert Markdown documents https://bit.ly/47Pd4Qn

Show HN: Offline macOS app to convert Markdown documents Hi HN, I've just launched DocFlex, an offline macOS app that converts Markdown documents into over 30 formats like PDF, HTML, EPUB, LaTeX, and more. Why I built it: As someone who frequently works with Markdown, I found it cumbersome to convert documents into different formats, especially when dealing with multiple files. Online converters weren't ideal due to privacy concerns and the need for an internet connection. So, I created DocFlex to make the process seamless and entirely offline. Key Features: 100% Offline: All conversions happen locally on your machine. Your documents are never sent to any servers. Batch Conversion: Convert multiple Markdown documents at once. 30+ Formats Supported: Export to PDF, HTML, EPUB, LaTeX, JSON, and many more. Native macOS App: Lightweight and focused solely on conversion without any unnecessary bloat (only installs basicTeX and pandoc). Download: You can download it here: https://bit.ly/4dou9BH I'd love to get your feedback and answer any questions you might have! https://bit.ly/4dou9BH September 30, 2024 at 11:51PM

Show HN: Fin.flights 2.0 – AI-powered flight search https://bit.ly/4dmb4Ag

Show HN: Fin.flights 2.0 – AI-powered flight search fin.flights is an AI-powered flight search tool that uses natural language processing to find the best flights based on user queries. just released version 2.0 with significant improvements: - No login required: Start searching immediately without creating an account - Advanced AI: Utilizing latest LLMs for more accurate flight results - Natural language interface: Type queries as you would ask a friend - Global coverage: Searches flights worldwide with multi-language support - Free to use: Only upgrade if you find it valuable How it works: 1. Enter a natural language query (e.g., "cheapest business class flights from NYC to Tokyo in the next 3 months with max 1 stopover") 2. Our AI interprets the query and searches across multiple airlines and booking platforms 3. Results are displayed instantly, sortable by price, duration, or best value I built this because existing flight search engines often require too many inputs and don't offer the flexibility of natural language queries. Myy goal is to make flight search as simple as asking a knowledgeable friend. I'd love to get feedback from the HN community on the user experience, AI accuracy, and any features you'd like to see added. https://bit.ly/4dwVNfY September 29, 2024 at 11:02PM

Show HN: htmgo - build simple and scalable systems with golang + htmx Hey all, I just wanted to share a project I've been working on for the past month. After years of heavy frameworks, I really like the idea of using htmx, but it’s a little too low level for me and needs a thin layer above it to facilitate things like components, better syntax with complex JS inside of an attribute, etc To try and solve this problem with a very minimal stack (golang + htmx) that I've been really enjoying, I'm building this project to cater to my needs and was thinking it would be useful for other developers. https://bit.ly/401p7s7 September 28, 2024 at 10:34PM

Show HN: Iceoryx2 – Fast IPC Library for Rust, C++, and C https://bit.ly/47GMY21

Show HN: Iceoryx2 – Fast IPC Library for Rust, C++, and C Hello everyone, Today we released iceoryx2 v0.4! iceoryx2 is a service-based inter-process communication (IPC) library designed to make communication between processes as fast as possible - like Unix domain sockets or message queues, but orders of magnitude faster and easier to use. It also comes with advanced features such as circular buffers, history, event notifications, publish-subscribe messaging, and a decentralized architecture with no need for a broker. For example, if you're working in robotics and need to process frames from a camera across multiple processes, iceoryx2 makes it simple to set that up. Need to retain only the latest three camera images? No problem - circular buffers prevent your memory from overflowing, even if a process is lagging. The history feature ensures you get the last three images immediately after connecting to the camera service, as long as they’re still available. Another great use case is for GUI applications, such as window managers or editors. If you want to support plugins in multiple languages, iceoryx2 allows you to connect processes - perhaps to remotely control your editor or window manager. Best of all, thanks to zero-copy communication, you can transfer gigabytes of data with incredibly low latency. Speaking of latency, on some systems, we've achieved latency below 100ns when sending data between processes - and we haven't even begun serious performance optimizations yet. So, there’s still room for improvement! If you’re in high-frequency trading or any other use case where ultra-low latency matters, iceoryx2 might be just what you need. If you’re curious to learn more about the new features and what’s coming next, check out the full iceoryx2 v0.4 release announcement.

Show HN: Open-source Docker image to run Chrome browsers in your cloud https://bit.ly/3N3NeOR

Show HN: Open-source Docker image to run Chrome browsers in your cloud If you’ve ever worked with web scraping or automation using Puppeteer or Playwright, you know that running Chrome can be tricky. While headless mode (Chrome with no display) often works, some page elements only render in headed mode, forcing you to run Chrome with a display. This usually means bloating your Dockerfile with complex dependencies like xvfb. Updating your server or Lambda container to handle this can increase costs and lead to dependency hell. The Solution: I’ve built a streamlined solution—a Docker image that runs Chrome with all its necessary dependencies and exposes a FastAPI interface. This decouples the browser logic from your main codebase, letting you focus on scraping or automation without worrying about the underlying setup. The container exposes a WebSocket endpoint at ws://localhost:8000/ws, allowing you to connect Playwright or Puppeteer over Chrome DevTools Protocol (CDP). For example: browser = await pw.chromium.connect_over_cdp('ws://localhost:8000/ws') Each connection to the WebSocket spins up a new Chrome session in headed mode, and you can run multiple sessions concurrently. Unlike other solutions, Finic is fully open-source (Apache 2.0 licensed). You can try it by pulling the official Docker image or cloning the repo at Finic on GitHub ( https://bit.ly/3XKPBw6 ) and running `docker-compose up --build`. This approach simplifies handling Chrome for scraping, saves on cloud costs, and keeps your setup clean. Give it a try! https://bit.ly/3ZCDzq8 September 27, 2024 at 04:06PM

Show HN: A tool that turns everyday computers into your own AI cloud https://bit.ly/3ZDxbit

Show HN: A tool that turns everyday computers into your own AI cloud I have a favour to ask. I’ve been working for a while on Kalavai, a project to make distributed AI easy. There are brilliant tools out there to help AI hobbyists and devs on the software layer (shout out to vLLM and llamacpp amongst many others!) but it’s a jungle out there when it comes to procuring and managing the necessary hardware resources and orchestrating them. This has always led me to compromise on the size of the models I end up using (quantized versions, smaller models) to save cost or to play within the limits of my rig. Today I am happy to share the first public version of our Kalavai client (totally free, forever), a CLI that helps you build an AI cluster from your everyday devices. Our first use case is distributed LLM deployment, and we hope to expand this with the help of the community. Now, the favour! I’d love for people interested in AI at scale (bigger than a single machine) to give it a go and provide honest feedback. Do you share our motivation? If you tried Kalavai, did you find it useful? What would you like it to do for you? What are your painpoints when it comes to using large LLMs? https://bit.ly/3zoGHve September 27, 2024 at 07:12PM
