Show HN: Detecting collision between 500k circles below 5ms https://ift.tt/NivBXyF

Show HN: Detecting collision between 500k circles below 5ms Heya. I created a flexible collision engine for broad detection in C that's also pretty fast. Personally that's my best, so I wanted to show it here. Although... still not as fast as DragonEnergy's one that supposedly handled millions of agents bouncing off each other every frame on an old i3, haha. I hope I get better at this! He set the bar pretty high for me. I was considering including some small function that tries finding the nearest entity, although I think it might be better to simply use query for that matter. Perhaps in the future I will get a good idea of how to do that more efficiently. This is not a clickbait. Although generally you also call other functions in a tick, a collision check between 500,000 circles ("circles", not "squares", because distance is checked and forces are applied based on the angle between) is done below 5ms on not really that demanding hardware. I achieve lower times than that on my budget laptop, slightly more on my PC (yeah, weird). The total time spent in a tick is 3-4 times that. https://ift.tt/gHtkKaB January 2, 2023 at 01:38AM

Show HN: I made a simple, open source, chromatic tuner mobile app https://ift.tt/7asLRqC

Show HN: I made a simple, open source, chromatic tuner mobile app I'm a musician by night, software developer by day, and one of the minor frustrations I've always had was trying to find a simple tuner app for my phone. Looking at both the iOS and Android app stores, you'll find a lot of the top tuner apps are rather bloated with ads or subscription callouts. I thought I'd create a dead-simple minimalistic chromatic tuner the way I would like it - open the app, and tune my guitar. I also wanted to delve a bit into mobile development, as my main focus is in web with NodeJS and React. I chose React Native since it was the easiest to understand coming from React. Flutter was also an option since the company I work for has a team working in that, but I thought it would be a bit too much effort to learn Dart. I learned a bit more about React rendering with this project as well. The main issue I had was trying to have a React state variable be constantly updated with any frequencies detected from the mic input, but that ended up causing substantial slowdown due to so many rerenders, so I opted to use a React ref to maintain any detections, and then only update the React state when there was an actual note. The apps you can find on the both the iOs App Store and Google Play (free!). https://ift.tt/P1bgNux https://ift.tt/KoTAMGX...

Show HN: OpenAI-powered semantic search for the All-In Podcast https://ift.tt/yVU6RP3

Show HN: OpenAI-powered semantic search for the All-In Podcast My favorite podcast is the All-In Pod, but search and discovery is tough for podcasts. So I built a semantic search index that lets you search across every episode of the pod with Google-level accuracy. It uses OpenAI's latest ada-2 embedding model and Pinecone to index the embeddings + k-NN search. Wrapped up in a Next.js + Vercel webapp. The project is designed to work with any YouTube channel / playlist. I'm just using All-In as a demo. Would love to hear feedback & suggestions. Open source here: https://ift.tt/F1r5Moj Note that the source is designed to work with any YouTube playlist / channel. I'm just using the All-In Podcast as a demo because it's my favorite. https://ift.tt/Av1Cc5N December 31, 2022 at 03:11AM

Show HN: CFR Explorer – Finding aviation answers using AI I've been wondering how can recent advances in AI can help with exploring regulations (currently related to aviation). Here is a beta app which uses embeddings to search and then uses GPT to quickly provide pilots with answers to aviation regulations in Title 14. Please note that this is a beta version, so errors may occur and you should always verify the response. I welcome feedback and suggestions to help improve the app. If you find an answer helpful, don't forget to give it a thumbs up, and if you think an answer could be improved, please give it a thumbs down. https://ift.tt/sXd8FQg December 30, 2022 at 02:06AM
