Show HN: Cerebellum – Open-Source Browser Control with Claude 3.5 Computer Use https://ift.tt/VzUsoh9

Show HN: Cerebellum – Open-Source Browser Control with Claude 3.5 Computer Use Hi HN! I was mesmerized by the Claude Computer Use reveal last week and was specifically impressed by how well it navigated websites. This motivated me to create Cerebellum, a library that lets an LLM take control of a browser. Here is a demo of Cerebellum in action, performing the goal “Find a USB C to C cable that is 10 feet long and add it to cart” on amazon.com: https://youtu.be/xaZbuaWtVkA?si=Tq9lE6BXv9wjZ-qC Currently, it uses Claude 3.5 Sonnet’s newly released computer use ability, but the ultimate goal is to crowdsource a high quality set of browser sessions to train an open source local model. Checkout the MIT licensed repo on github ( https://ift.tt/4VhPlHw ) or install the library from npm ( https://ift.tt/EatVOid ) Looking for feedback from the HN community, especially on: What browser tasks would you use an LLM to complete? Thanks again for taking a look! https://ift.tt/4VhPlHw October 31, 2024 at 09:49PM

Show HN: Modus, serverless framework for intelligent APIs powered by WebAssembly https://ift.tt/p7d6Xfu

Show HN: Modus, serverless framework for intelligent APIs powered by WebAssembly Modus is an open-source, serverless framework for building APIs powered by WebAssembly. It simplifies integrating AI models, data, and business logic with sandboxed execution. We built Modus to put code back at the heart of development. You write a function. export function sayHello(name: string): string { return `Hello, ${name}!`; } Then, Modus: - extracts the metadata of your functions - compiles your code with optimizations based on the host environment - caches the compiled module in memory for fast retrieval - prepares an invocation plan for each function - extracts connections, models, and other configuration details from the app’s manifest - generates an API schema and activates the endpoint You query the endpoint. query SayHello { sayHello(name: "world") } In a few milliseconds, Modus: - loads your compiled code into a sandboxed execution environment with a dedicated memory space - runs your code, aided by host functions that power the Modus APIs - securely queries data and AI models as needed, without exposing credentials to your code - responds via the API result and releases the execution environment Now you have a production ready scalable endpoint for your AI-enabled app. AI-ready when you’re ready. Launch and iterate. Read more in the announcement blog post: https://ift.tt/bWmG79x...

Show HN: Trench – Open-source analytics infrastructure https://ift.tt/VKUwkMY

Show HN: Trench – Open-source analytics infrastructure Hey HN! I want to share a new open source project I've been working on called Trench ( https://trench.dev ). It's open source analytics infrastructure for tracking events, page views, and identifying users, and it's built on top of ClickHouse and Kafka. https://ift.tt/heCDfNy I built Trench because the Postgres table we used for tracking events at our startup ( http://frigade.com/ ) was getting expensive and becoming a performance bottleneck as we scaled to millions of end users. Many companies run into the same problem as us (e.g. Stripe, Heroku: https://ift.tt/pPCNWQI ). They often start by adding a basic events table to their relational database, which works at first, but can become an issue as the application scales. It’s usually the biggest table in the database, the slowest one to query, and the longest one to back up. With Trench, we’ve put together a single Docker image that gives you a production-ready tracking event table built for scale and speed. When we migrated our tracking table from Postgres to Trench, we saw a 42% reduction in cost to serve on our primary Postgres cluster and all lag spikes from autoscaling under high traffic were eliminated. Here are some of the core features: * Fully compliant with the Segment tracking spec e.g. track(), identify(), group(), etc. * Can handle thousands of events per second on a single node * Query tracking data in real-time with read-after-write guarantees * Send data anywhere with throttled and batched webhooks * Single production-ready docker image. No need to manage and roll your own Kafka/ClickHouse/Nodejs/etc. * Easily plugs into any cloud hosted ClickHouse and Kafka solutions e.g. ClickHouse Cloud, Confluent Trench can be used for a range of use cases. Here are some possibilities: 1. Real-Time Monitoring and Alerting: Set up real-time alerts and monitoring for your services by tracking custom events like errors, usage spikes, or specific user actions and sending that data anywhere with Trench’s webhooks 2. Event Replay and Debugging: Capture all user interactions in real-time for event replay 3. A/B Testing Platform: Capture events from different users and groups in real time. Segment users by querying in real time and serve the right experiences to the right users 4. Product Analytics for SaaS Applications: Embed Trench into your existing SaaS product to power user audit logs or tracking scripts on your end-users’ websites 5. Build a custom RAG model: Easily query event data and give users answers in real-time. LLMs are really good at writing SQL The project is open-source and MIT-licensed. If there’s interest, we’re thinking about adding support for Elastic Search, direct data integrations (e.g. Redshift, S3, etc.), and an admin interface for creating queries, webhooks, etc. Have you experienced the same issues with your events tables? I'd love to hear what HN thinks about the project. https://ift.tt/o8eVXzH October 25, 2024 at 09:07PM

Show HN: I built EstateLead AI – lead generator boosting agent productivity 10x https://ift.tt/1cZawNu

Show HN: I built EstateLead AI – lead generator boosting agent productivity 10x As a former real estate agent, I discovered a critical pain point in early 2023. Every day, I spent 3-4 hours manually copying leads from Zillow - phone numbers, emails, and property details. This tedious process was stealing valuable time I could have spent with clients. I realized this wasn't just my problem. Thousands of agents were stuck in this same time-consuming routine, manually gathering leads one by one. There had to be a better way. Over the next a months, I faced numerous challenges building EstateLead AI: - Ensuring reliable data extraction - Maintaining compliance with data privacy regulations - Creating an intuitive interface for non-technical users - Scaling the system to handle thousands of requests After countless iterations and feedback from 50+ beta testers, I'm excited to launch EstateLead AI with these key features: Key Features: - One-click lead extraction from Zillow listings - Up to 18,000 leads per month with phone numbers - Export to Excel/CSV for easy CRM integration - Coverage for both US and Canadian markets - Built-in compliance with data protection rules - Simple browser extension interface The tool has already helped 600+ agents save 40+ hours per week on lead generation. Early users report a 10x increase in their prospecting efficiency. I'd love for the HN community to try it out and share your thoughts. What features would make this even more valuable for real estate professionals? Try it here: https://ift.tt/h4HvbDL P.S.

Show HN: PreCog AI – Automatic AI Model Selection for Any Task https://ift.tt/5nlfbxB

Show HN: PreCog AI – Automatic AI Model Selection for Any Task Hi HN, I'm one of the co-founders of PreCog AI, a project my friend and I started to make the best AI models more accessible. PreCog AI is a chatbot that automatically picks and answers with the best AI model for whatever task you throw at it. We made PreCog public on Monday and are getting great feedback. Originally built as an internal tool to help our small team reduce costs (paying for various chatbots) and get better AI output, PreCog has helped us so much with our workflow and ideation that we just had to share it. Key Features of PreCog - AI Model Matchmaking: With access to 18 models, PreCog automatically matches your questions with the most fitting AI model based on the task. - Versatile Adaptation: Works with any task, from coding to creative writing, giving you the right tool for the job. -Ongoing Updates: Stay current with AI advancements using the latest LLM leaderboard data (we are constantly adding and changing our leaderboard). See the leaderboard here - https://ift.tt/QCsrfGa -Preferred Model Selection: If you have a preferred model, choose it, and PreCog will use that model exclusively to respond. How PreCog Works: PreCog analyzes your query, references the model leaderboard, and then matches your query with the highest-ranked AI for that niche task. Delivering high-quality, task-specific output. PreCog's Model Leaderboard ranks AI models through over a million human comparisons, evaluated and presented on an Elo-scale. The dataset used to build the PreCog Leaderboard is from ChatBot Arena by https://lmarena.ai/ . Researchers from UC Berkeley SkyLab and LMSYS developed the battle framework to produce the dataset. I love feedback, questions, and critiques it helps me and my friend develop with the user in mind. You can reach me at anytime at: info@ubik.studio https://ift.tt/tFKyZce October 25, 2024 at 12:25AM

Show HN: Srcbook – Self-hosted alternative to AI app builders https://ift.tt/rDKlW7Q

Show HN: Srcbook – Self-hosted alternative to AI app builders Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago ( https://ift.tt/5RhSXlF ) and the response was encouraging, but we kept hearing that people wanted to build interactive apps. Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that's what you prefer. When the AI makes changes you can review the files diff like you would a GitHub pull request, and toggle between versions to view the visual diff. Try it now: npx srcbook@latest start It’s surprisingly good at building apps, especially with the latest claude model sonnet3.5 that came out yesterday. Here’s a video showing building and iterating on a ticket tracker MVP in a few minutes https://www.youtube.com/watch?v=jYOmzasvP74 Key features: - bring you own API key - diff viewer - apply/undo mechanism to see the visual diff - export the code - code is OSS under apache2 https://ift.tt/qLSwa8G October 23, 2024 at 10:31PM

We're both developers at Medusa (an open source commerce platform) and we've launched our 2.0 version today after a year of working on a more modular commerce architecture. We built our own workflow engine to perform actions on multiple modules with the ability to revert each step incase a failure occurs at some point in the lifecycle. Modules are encapsulated group of related logic - like product management, fulfillment, orders, promotions, etc. We've also built our own query engine based on GraphQL that you can use to query across modules or even external services - like Sanity or other CMS. Tinloof did a very cool demo of this earlier today. The whole point of our 1 year work was to make things easily customizable and be able to easily work with the plethora of external services every commerce company would have to work with. It takes less than a minute to get started locally. Give this a shot and let us know if you've got any feedback. https://ift.tt/dLNaCfy October 23, 2024 at 11:04PM

Show HN: Open-Source Zero-Shot Image Model Server Enabling Model Feedback https://ift.tt/vWR0ePC

Show HN: Open-Source Zero-Shot Image Model Server Enabling Model Feedback Hi everyone! Here is an open source implementation of a decently performant server hosting zero-shot image models (CLIP for image classification, OWL-ViT-ST for object detection), with an extra algorithm to allow users to give the models feedback when they make mistakes! We built a company off this flavor of tech two years ago and have clients who are currently using our commercial API. We are now moving on to other projects but want to make sure our clients still have access to the approaches that they've grown to rely on, so we're open sourcing a simple implementation that they'll be able to use after we've shut down our hosted API! I used to work at a robotics startup. After a while it seemed clear that the biggest limiting factor in our ability to ship new models wasn't innovation on model architecture, it was access to relevant, high-quality training data. Around that time CLIP was released, which got me thinking about the idea of having models with world-knowledge baked in so as to reduce the amount of training data required. A year later when Stable Diffusion dropped, my cofounder Ben Brooks and I took the plunge and founded DirectAI, where we worked on building ways to get performant models without collecting any training data, using the knowledge stored in pretrained models instead. In this implementation, we replace the linear classification head typically used in zero-shot image classifiers with a modified nearest neighbors method that lets you use multiple examples (both positive and negative) per-class to make sure the decision boundary the model is using is more aligned with what you had in mind. Our clients have found it very useful for things from interior design to content moderation to sports analytics, building models that are either too niche to be supported by a traditional cloud-hosted computer vision API or are subtly different from the models that existing cloud APIs host. For example, one of our clients wants to filter out all images containing alcohol. Hive has an API for that, but Hive explicitly allows red solo cups that don't obviously have anything alcoholic in them, whereas our client wanted to filter those out too! Feedback is welcome! There are still bugs in the Gradio frontend / codebase in general, but I have a deadline and need to be working on new stuff at a new job starting Monday so I thought I would just go ahead and get it out there! I've never tried to publish a real open source piece of code before and I must admit I am quite nervous! https://ift.tt/fEFyUBc October 20, 2024 at 01:51AM

Show HN: A fair Product Hunt alternative https://ift.tt/eoYldSQ

Show HN: A fair Product Hunt alternative Over the past few weeks, I’ve been developing Simple Lister, a platform built to support indie product creators and give them a fair shot. If you’ve launched on Product Hunt recently, you might have noticed that only featured products get the spotlight, while others struggle for visibility. Why Simple Lister? Simple Lister aims to fix this by offering a more transparent and fair approach for product launches. Here’s how we do it: • No favoritism: Every product gets an equal chance, and we don’t play favorites. • Daily Underdog Feature: Each day, we highlight one underdog product to give them extra visibility and support. • No hidden fees: There are no surprise costs. We have a simple submission fee, and that’s it—no pay-to-play or hidden charges. Also we have a long to do list to do better. Why does this matter? After launching on Product Hunt ourselves, we realized how tough it is for smaller creators to get any attention unless they’re featured. Simple Lister is here to champion those indie products that deserve to be seen by a wider audience. The platform is new and evolving, and I’m constantly working to make it better. If you’ve got feedback or questions, don’t hesitate to reach out! Thanks for your support, and I’d be happy if you submit your products! https://ift.tt/qnfhDYT October 16, 2024 at 11:11PM

I used ChatGPT 4o-mini to generate details for the 12,000 soldiers involved in the game. Notably, I had to supply names because it couldn't introduce sufficient variety. I also had to add randomly generated adjectives for the soldiers; otherwise, the prompts were too similar, even with different seeds and temperatures. Initially, I used Claude (which I usually prefer), but it made every soldier a former carpenter’s apprentice. Since this is a game and your actions should matter, instead of generating one block of text, I had it generate JSON by providing a template with cues for different things that might happen to the soldier. I used these to dynamically assemble a story for each casualty. For example: { "briefBio": "Tell me a little bit about the solider", // Putting this first is critical to introduce variety … "lastThoughtsArtilleryDead": "What are his last thoughts as he dies from an artillery strike" , … "effectOnOthersShotInjured": "What are the long term impacts on the people who care about him when he is seriously injured by a bullet wound", } The prompt template can be found here: https://ift.tt/FzpZtTS... The underlying simulation was programmed using Unity ECS (Entity Component System) and simulated, to some degree, each soldier and artillery piece. Casualties were taken in entity order, so there's some predictability regarding when each name gets added to the list, though it isn't completely deterministic. The area where I skimped the most was the UI, but the game is in a playable state if you're willing to look at the center column and figure out what the numbers mean. A final notable learning is that Unity UI toolkit (their modern, web dev like solution) performs significantly better on the web than in the native linux build, at least on the 2022 LTS version of Unity. This suggests that they may be leveraging the rendering efficiencies built into browsers. https://ift.tt/Hxn3kEQ October 14, 2024 at 11:02PM

Show HN: I made a git rebase TUI editor https://ift.tt/tnciNOZ

Show HN: I made a git rebase TUI editor I use interactive rebase quite often, and particularly like the editor bundled with IntelliJ. But I do not always work with IntelliJ, and am not 'fluent' with Vim, so I tried to replicate roughly the same rebase experience within a TUI. I used a small TUI OCaml project i made last year. The notable features are: - Move commits up and down, fixup, drop - Rename commits from the editor (without having to stop for a reword during the rebase run) - Visualize modified files along commits - 'Explode' a commit ,creating a commit for each modified file (a thing I found myself doing quite often) Feedbacks (both on the tool and the code) and contributions welcome, hope it could fit other people needs too ! https://ift.tt/d0vPEjm October 14, 2024 at 03:03AM

Show HN: Aurelius – a local-first, distraction-free writing app Hey HN! I've been working on yet another writing app called Aurelius ( https://aurelius.ink ). I built Aurelius primarily for myself and I've been writing with it everyday. I thought I'll share this here. Here are the features: - Local-first, but can sync data between different browsers or devices without signup. Sync is also end-to-end encrypted. - Progressive web app and offline functionality. - Rich-text editing with support for Markdown shortcuts. - Keyboard shortcuts for most actions in the app. - Writing sessions timer for tracking your daily writing. - Focus-mode which hides almost everything except the editor. - Music player that plays focus music like lofi, chillhop, etc. You can also use a Youtube video or playlist of your choice. Give it a try and let me know your thoughts. Thank you! https://aurelius.ink/ October 13, 2024 at 07:52PM

Show HN: QuickDessert – generate quick dessert recipes and adjust Ingredients https://ift.tt/FIJDSyj

Show HN: QuickDessert – generate quick dessert recipes and adjust Ingredients It’s not just your average recipe site – they’ve got an AI-powered feature that generates custom dessert recipes based on your preferences or available ingredients! If you’re short on time or ingredients, the site lets you tweak recipes on the fly. You can adjust ingredients to suit your pantry, dietary preferences, or time constraints, and the AI will instantly generate a new dessert idea for you. Super handy for those moments when you have a sweet tooth but not everything in your kitchen! For example, I tried out a brownie recipe and swapped out sugar for honey – worked like a charm! The flexibility and ease make it really fun to experiment with desserts without spending hours searching for ideas or second-guessing ingredient swaps. https://ift.tt/23EagnP October 9, 2024 at 09:21PM

Show HN: Arch – an intelligent prompt gateway built on Envoy https://ift.tt/dO1Y4Vq

Show HN: Arch – an intelligent prompt gateway built on Envoy Hi HN! My name is Adil Hafeez, and I am the Co-Founder at Katanemo and the lead developer behind Arch - an open source project for developers to build faster, generative AI apps. Previously I worked on Envoy at Lyft. Engineered with purpose-built LLMs, Arch handles the critical but undifferentiated tasks related to the handling and processing of prompts, including detecting and rejecting jailbreak attempts, intelligently calling “backend” APIs to fulfill the user’s request represented in a prompt, routing to and offering disaster recovery between upstream LLMs, and managing the observability of prompts and LLM interactions in a centralized way - all outside business logic. Here are some additional key details of the project, * Built on top of Envoy and is written in rust. It runs alongside application servers, and uses Envoy's proven HTTP management and scalability features to handle traffic related to prompts and LLMs. * Function calling for fast agentic and RAG apps. Engineered with purpose-built fast LLMs to handle fast, cost-effective, and accurate prompt-based tasks like function/API calling, and parameter extraction from prompts. * Prompt guardrails to prevent jailbreak attempts and ensure safe user interactions without writing a single line of code. * Manages LLM calls, offering smart retries, automatic cutover, and resilient upstream connections for continuous availability. * Uses the W3C Trace Context standard to enable complete request tracing across applications, ensuring compatibility with observability tools, and provides metrics to monitor latency, token usage, and error rates, helping optimize AI application performance. This is our first release, and would love to build alongside the community. We are just getting started on reinventing what we could do at the networking layer for prompts. Do check it out on GitHub at https://ift.tt/YBoALOx . Please leave a comment or feedback here and I will be happy to answer. (I did make a mistake earlier not properly tagging the title with Show HN and the post didn't end up in Show HN. Later I updated the title but then my text started showing up as a comment.

Show HN: Donobu – Mac App for Web Automation and Testing https://ift.tt/Ai4mQcn

Show HN: Donobu – Mac App for Web Automation and Testing Been working on a desktop app for Mac that lets you create web flows and rerun them ( https://www.donobu.com/ ). You can optionally use AI (BYOK: bring your own keys) to create flows for you and to do other interesting things, like making vision-based semantic assertions. Also, your data lives on your own filesystem, and we do not see any of it (further still, there is no phoning home at all). A nice benefit of this being a desktop app rather than a SAAS product, is that if you happen to be developing/iterating on a webpage locally, this has no problem hooking into it. What this intends to be a good fit for: - Testing web pages, especially locally. - Exploring random webpages with a stated objective. - Automating tedious flows. Rerunning a flow won't get caught up on using a single selector (many websites randomize element IDs, for instance), there is smart failover using a prioritized list of selectors. - Getting a quick draft of an end-to-end test in Javascript. What this is a bad fit for: - Mass web scraping (too slow). - Adversarial websites. What we are still working out: - Click-and-drag operations. - Websites that are primarily controlled from canvas. - Smoothing out UI/UX (we are two backend engineers trying our best, and are handedly outgunned by real frontend engineers). Fun things to try: - Asking it to assert that a webpage has a certain theme. - Asking it to run an accessibility report for a page (uses https://ift.tt/uCRgFJs ). - Asking it to run a cookie report for a page. The tech: - Java 21 for the main business logic. - Javalin 6 for the web framework ( https://javalin.io/ ). - Playwright for controlling the browser ( https://ift.tt/c3xH7Ch ). - Axe for running accessibility reports ( https://ift.tt/uCRgFJs ). Critical feedback is welcome. Thanks for trying it out! Cheers, -Justin and Vaz https://www.donobu.com/ October 9, 2024 at 11:18PM

Show HN: FinetuneDB – AI fine-tuning platform to create custom LLMs https://ift.tt/F6fD583

Show HN: FinetuneDB – AI fine-tuning platform to create custom LLMs Hey HN! We’re building FinetuneDB ( https://finetunedb.com/ ), an LLM fine-tuning platform. It enables teams to easily create and manage high-quality datasets, and streamlines the entire workflow from fine-tuning to serving and evaluating models with domain experts. You can check out our docs here: ( https://ift.tt/6SJC40M ) FinetuneDB exists because creating and managing high-quality datasets is a real bottleneck when fine-tuning LLMs. The quality of your data directly impacts the performance of your fine-tuned models, and existing tools didn’t offer an easy way for teams to build, organize, and iterate on their datasets. We’ve been working closely with our pilot customers, both AI startups and more traditional businesses like a large newspaper, which is fine-tuning models on their articles to automate content generation in their tone of voice. The platform is built with an end-to-end workflow in mind, from dataset building, fine-tuning, serving, and evaluating outputs. The centerpiece is a version-controlled, no-code dataset manager where you can upload existing datasets in JSONL, use production data, or collaborate with domain experts to create high-quality datasets for custom use cases. We also offer evaluation workflows that allow non-technical contributors to annotate data, review model outputs, and refine responses (LLM-as-judge also available). We offer: - A free tier for developers and hobbyists who want to streamline dataset management. - Business-tier with full feature access for teams, using per-seat pricing. - A custom tier for model hosting, custom integrations, and self-hosting. Most users still use OpenAI models, but if you're working with open-source LLMs, we offer pay-as-you-go pricing for serverless inference for Llama and Mistral models with up to €100 in free credits to get started. We're in public beta right now, so any feedback—whether it’s about features, usability, or anything else—would be incredibly valuable. If you've worked on fine-tuning models before or are curious about custom LLMs, we’d love to hear from you. Our goal is to make the fine-tuning process more accessible and help more companies leverage their data and domain experts to create custom LLMs. Thanks for checking it out! https://finetunedb.com October 9, 2024 at 10:44PM

Show HN: PostalAgent – Send Postcards online by circling areas on a Google Map Hey HN, I just launched https://PostalAgent.com , a site that lets you easily send highly targeted postcards to specific neighborhoods. I originally built this site 5 years ago but shut it down when my full time engineering job became too demanding, but recently I did a full rewrite with many new features. To start you can select an area using a City, State, or even by circling specific areas on a Google Map. Then, you can refine your results and filter on specific demographics, like household income, home value, rental status, etc You can also search for Businesses rather than consumers, and even filter by franchise type, presence of email, etc. I was able to get a few clients signed up very quickly, mostly home services type businesses and real estate agents, but I think it could be used by many types of businesses. I have a few customers that are only using the mailing list feature without sending postcards, likely for cold email or other marketing outreach. I'm looking for a bit of feedback from the community. https://postalagent.com October 7, 2024 at 11:28PM

Show HN: CodeAir – Control VS Code from Your Phone Hey HN, Inspired by the classic "Compiling" XKCD comic ( https://ift.tt/JiSgl3X ), I’ve built CodeAir (codeair.app) – an Android app and VS Code extension that turns your phone into a remote control for VS Code. With CodeAir, you can: - Control 800+ VS Code commands right from your phone. - Send text and image files directly into your workspace and even have the images transcribed using AI. So imagine taking a snapshot of a piece of code from a physical textbook and being directly able to run that inside VS Code. - Request screenshots from VS Code while AFK and get them delivered to your phone so you can monitor long builds or processes remotely when you're on a coffee break. - If you’ve got an OpenAI API key, you can even perform QnA over your transferred files and images. I made this tool to help monitor long builds or tests when I’m AFK, but it’s useful for so much more! It’s super niche, but I hope some of you find it helpful. Check it out at codeair.app and let me know what you think. Feedback is very welcome! https://www.codeair.app October 5, 2024 at 08:05PM

Show HN: open source framework OpenAI uses for Advanced Voice https://ift.tt/neik2G0

Show HN: open source framework OpenAI uses for Advanced Voice Hey HN, we've been working with OpenAI for the past few months on the new Realtime API. The goal is to give everyone access to the same stack that underpins Advanced Voice in the ChatGPT app. Under the hood it works like this: - A user's speech is captured by a LiveKit client SDK in the ChatGPT app - Their speech is streamed using WebRTC to OpenAI’s voice agent - The agent relays the speech prompt over websocket to GPT-4o - GPT-4o runs inference and streams speech packets (over websocket) back to the agent - The agent relays generated speech using WebRTC back to the user’s device The Realtime API that OpenAI launched is the websocket interface to GPT-4o. This backend framework covers the voice agent portion. Besides having additional logic like function calling, the agent fundamentally proxies WebRTC to websocket. The reason for this is because websocket isn’t the best choice for client-server communication. The vast majority of packet loss occurs between a server and client device and websocket doesn’t provide programmatic control or intervention in lossy network environments like WiFi or cellular. Packet loss leads to higher latency and choppy or garbled audio. https://ift.tt/YvzTh9j October 5, 2024 at 12:01AM

Show HN: FFmpeg-over-IP – Connect to remote FFmpeg servers https://ift.tt/bd8Nujs

Show HN: FFmpeg-over-IP – Connect to remote FFmpeg servers Dear HN, I’m excited to show case a personal project. It has helped me quite a bit with my home lab, I hope it can help you with yours too! ffmpeg-over-ip has two components, a server and a client. You can run the server in an environment with access to a GPU and a locally installed version of ffmpeg, the client only needs network access to the server and no GPU or ffmpeg locally. Both and client and the server need a shared filesystem for this to work (so the server can write output to it, and client can read from it). In my usecase, smb works well if your (GPU) server is a windows machine, nfs works really well for linux setups. This utility can be useful in a number of scenarios: - You find passing through a (v)GPU to your virtual machines complicated - You want to use the same GPU for ffmpeg in multiple virtual machines - Your server has a weak GPU so you want to use the GPU from your gaming machine - Your GPU drivers in one OS are not as good as another (AMD RX6400 never worked for me in linux, but did so in windows) I’ve posted some instructions in the Github package README, please let me know if they are unclear in any way and I’ll try to help!

Show HN: Chess Puzzle Bot – Puzzles vs. Stockfish https://ift.tt/ybaZxKv

Show HN: Chess Puzzle Bot – Puzzles vs. Stockfish I made a website where you can play chess puzzles against Stockfish! When playing puzzles, neither Lichess nor Chess.com will accept a wrong move, which in my opinion spoils the resolution of the puzzle since only correct moves allow you to keep playing. So, I had the idea for a website where you can play chess puzzles, but if you make the wrong move, the puzzle turns into a game against Stockfish. This opens the door to either find alternative solutions or fail miserably (at some point you realize you are not following the puzzle any more). I think its a more engaging way to play puzzles! This is my first website, don't expect every div to be correctly centered. The mobile version may not be as polished but is still playable. https://ift.tt/NiIjfm6 Feedback is highly appreciated! https://ift.tt/NiIjfm6 October 4, 2024 at 11:01PM

Show HN: I made a super-simple image CDN Hi HN, MageCDN is a simple and affordable image hosting service I have been working on for the past few weeks. The idea came out of my own frustration with hosting and optimizing images for my blog. While platforms like Imgur make it really simple to upload images, they don't allow you to embed them. Services like Cloudinary, Imagekit exist, but I found them too complex for my needs. Plus, they get really expensive past their free tier. So, I started MageCDN with three simple goals: - pricing should be affordable and scale linearly. - basic image operations (resize, crop, optimize) should be doable within the app. - uploading and getting a link you can use should be fast and hassle-free. Would love to hear what you think! https://magecdn.com/ October 3, 2024 at 10:34PM

Show HN: Sourcebot, an open-source Sourcegraph alternative Hi HN, We’re Brendan and Michael, the creators of Sourcebot ( https://ift.tt/oFVhD0E ). Sourcebot is an open-source code search tool that allows you to quickly search across many large codebases. Check out our demo video here: https://youtu.be/mrIFYSB_1F4 , or try it for yourself on our demo site here: https://ift.tt/xmWyqVR While at prior roles, we’ve both felt the pain of searching across hundreds of multi-million line codebases. Using local tools like grep were ill-suited since you often only had a handful of codebases checked out at a time. Sourcegraph ( https://ift.tt/jdiefWE ) solves this issue by indexing a collection of codebases in the background and exposing a web-based search interface. It is the de-facto search solution for medium to large orgs, but is often cited as expensive ($49 per user / month) and recently went closed source ( https://ift.tt/LusTgvl ). That’s why we built Sourcebot. We designed Sourcebot to be: - Easily deployed: we provide a single, self-contained Docker image ( https://ift.tt/MS9TkQv... ). - Fast & scalable: designed to minimize search times (current average is ~73ms) across many large repositories. - Cross code-host support: we currently support syncing public & private repositories in GitHub and GitLab. - Quality UI: we like to think that a good looking dev-tool is more pleasant to use. - Open source: Sourcebot is free to use by anyone. Under the hood, we use Zoekt ( https://ift.tt/KBwFDYW ) as our code search engine, which was originally authored by Han-Wen Nienhuys and now maintained by Sourcegraph ( https://ift.tt/Qq8CkY2... ). Zoekt works by building a trigram index from the source code enabling extremely fast regular expression matching. Russ Cox has a great article on how trigram indexes work if you’re interested: https://ift.tt/H76Ok1o In the shorter-term, there are several improvements we want to make, like: - Improving how we communicate indexing progress (this is currently non-existent so it’s not obvious how long things will take) - UX improvements like search history, query syntax highlighting & suggestions, etc. - Small QOL improvements like bookmarking code snippets. - Support for more code hosts (e.g., BitBucket, SourceForge, ADO, etc.) In the longer-term, we want to investigate how we could go beyond just traditional code search by leveraging machine learning to enable experiences like semantic code search (“where is system X located?”) and code explanations (”how does system X interact with system Y?”). You could think of this as a copilot being embedded into Sourcebot. Our hunch is that will be useful to devs, especially when packaged with the traditional code search, but let us know what you think. Give it a try: https://ift.tt/oFVhD0E .
