Show HN: Hooper – AI-driven stats and highlights for basketball play https://ift.tt/HQ6L9ZD

Show HN: Hooper – AI-driven stats and highlights for basketball play Hey everyone, OP here. Wanted to share a bit more about Hooper — I started building it with a good friend of mine six months ago. We play a lot of pickup together and were arguing about who has a better jump shot and ended up hacking together an app to settle it The way Hooper works is you can record yourself using the app and ideally a tripod (optional). The app will track everyone, whether its a solo practice, a 3v3, or a 5v5. We think there’s a lot of stuff out there for basketball drills but what we really wanted Hooper to be for is actual game play. That means, it can do things like track multiple players, sync two half court recordings, and differentiate 2s vs 3s. Once you finish recording, it’ll process for a bit and then ask you to tag yourself (and optionally other players). Then it spits back out a few things: you can watch the full footage as well as a clipped version that's only the interesting plays; you can see highlights and offensive box stats for every player. When you sign up, you get a Hooper profile that tracks your overall stats across the sessions. You can also do things like build a mixtape from your highlights for insta. You can friend other players on Hooper to see their profile & comment on their games (also add us “grub” and “kangexpress”!) We’ve been in a closed beta for about 3 months now, fixing bugs and getting things to work with a set of early adopters. We are now starting our open beta ! If anyone here wants to try it out, you can just download the app on https://ift.tt/yXFpV7E . We are early in our journey, and lots of improvements to be made in the next few months, but we would love your feedback and ideas! https://www.hooper.gg July 25, 2024 at 03:09AM

Show HN: Voluntarily add warning labels to social media websites https://ift.tt/dQUKeHY

Show HN: Voluntarily add warning labels to social media websites A Chrome extension to voluntarily add informative warning labels to social media websites. There is a significant association between social media use and depression. Recently the surgeon general of the United States called on congress to require warning labels. While warning labels are not a sure-fire way to curb use, they can be effective provided that: - The warning must provide new information to users, and - The user must find the information credible https://ift.tt/qInQ7ja July 25, 2024 at 02:24AM

Show HN: Unsearch, an open source alternative to Google Chrome Sync https://ift.tt/BopPRWq

Show HN: Unsearch, an open source alternative to Google Chrome Sync I use several browsers between college, work and home and I like to have them synced so I can find websites I've searched for in a browser when I don't have access to it or access my bookmarks. I don't like the idea of using any of the sync services offered by the major browsers because of how they might use my data, because they lack some features I'd like to have, and because they all try to lock you into their ecosystem. So I'm building an open source cross-browser manager for browsing activity. I would love to hear your thoughts on this concept, and if you have any questions or suggestions, please let me know. https://ift.tt/E4BoPft July 24, 2024 at 10:48PM

Unsloth https://ift.tt/oCArEX3 makes finetuning Llama, Mistral, Gemma & Phi 2x faster, and use 50 to 70% less VRAM with no accuracy degradation. There's a custom backprop engine which reduces actual FLOPs, and all kernels are written in OpenAI's Triton language to reduce data movement. Also have an 2x faster inference only notebook in a free Colab as well! https://ift.tt/A4QLxbC... https://ift.tt/GhqBKvy July 24, 2024 at 02:00AM

Show HN: React Native Finisher Kit That'll Automate All the Complex Stuff https://ift.tt/9EmHA5i

Show HN: React Native Finisher Kit That'll Automate All the Complex Stuff Hey HN, I've been automating mobile builds since 2017, publishing a course on mobile automation back then. Over the years, I’ve configured Mobile CI/CD for various companies using Bitrise, Codemagic, GitHub Actions – over and over again. To simplify this repetitive process, I’ve created a React Native "finisher kit" that automates Mobile CI/CD setup. Here’s what it offers: - Initial setup with monorepo support, multiple environments, unified configuration, testing set up, features like Push or iOS Live Activities… - Easy app creation for App Stores + Fully automated code signing, building, deployment, - Single place for configuration (AWS), reusable for local development, builds and deployment either locally or in the cloud, - A seamless system to manage configurations for Apple, Fastlane, Google, and more… It allows you to create your Mobile CI/CD with any of these providers with a single CLI command and keep it up-to-date. Switch between providers just by changing the config. It supports both React Native CLI projects and Expo. I built it to save time and reduce the complexity of mobile app development, hoping it will be as helpful for you as it has been for me. I’d love to get your feedback and thoughts. Thanks!

Show HN: I made a task manager / calendar app to use it with my wife Hi HN, Two years ago, I started building Jinear as a side project for fun. Then my wife started using it to plan her PhD thesis. I added features as we needed them. After a while, my best friend started using it in his small company, so I thought maybe I could productize it. You can create tasks, set reminders, attach files, link your Google Calendar, etc. It can be used as a PWA. We've been using it daily. I would be happy to receive your feedback. Thanks. https://jinear.co July 22, 2024 at 10:04PM

Show HN: Create how-to videos and guides fast https://ift.tt/UXI5GeY

Show HN: Create how-to videos and guides fast Hey HN, I'm Kamal, a 20 year old builder from India, with a team of 4. I was building an AI-powered course builder initially, and once we started getting some paying customers biggest problem that we encountered was teaching them how to use the product. I wanted to create help centre but I couldn't, probably the procrastination, because I felt like it was a huge task. So, me and my co-founder decided to make creating videos and guides for this help centre fast and easy. This is where Kroto comes in, you just record a product/process walkthrough and it generates studio quality how-to videos with zoom-in and transition effects along with a step-by-step guide with GIFs for every action. Here's the demo: https://www.youtube.com/watch?v=JmeeNmpNepY I want to know if you guys also face similar issues, and want to get some feedback on the product. Biggest issues right now: Publishing time way too long, editor not optimised, no way to remove or add more zoom-ins in the video. https://www.kroto.one July 21, 2024 at 10:13PM

Show HN: Live Demo of GraphRAG with GPT-4o mini https://ift.tt/TX1cY8P

Show HN: Live Demo of GraphRAG with GPT-4o mini Hi HN, Microsoft recently open-sourced the GraphRAG framework, which enables more contextual responses than traditional vector-based RAG, especially for summarization-focused queries on textual data. However, a common critique is the LLM costs for constructing the knowledge graph. With the newly released GPT-4o mini, working with GraphRAG would now be ~30x cheaper. We built a demo with quarterly earning call transcripts from a few S&P 100 companies comparing GraphRAG with GPT-4o, GraphRAG with GPT-4o mini, and Baseline RAG. Try out the demo here: https://ift.tt/sWAJ3Nq Looking forward to your feedback! https://ift.tt/sWAJ3Nq July 21, 2024 at 12:11AM
