Show HN: A tool for motion-capturing 3D characters using a VR headset https://ift.tt/5CGMnNq

Show HN: A tool for motion-capturing 3D characters using a VR headset Hi everyone! I'm one of the authors of this project. The demo you see here is powered by a tool that I recently helped develop and open-source at Shopify called handy. You can find the repo here: https://ift.tt/9zcYWty Most people don't realize that VR headsets have become really capable motion capture platforms, so we decided to release this tool to bring motion capture into the hands of everyone who owns a headset. With a cheap Quest 2 you can capture your hands using the headset's hand-tracking feature and your head. With an expensive Quest Pro you could capture your facial expressions using the headset's eye and face-tracking features. Thanks for checking this project out! I'm here to answer questions if you have any. https://ift.tt/ALVh2Z1 January 17, 2023 at 07:33PM

Show HN: Semantic Search for Confluence Workspace https://ift.tt/un3Qti0

Show HN: Semantic Search for Confluence Workspace Hello Hacker News! I built Sleuth, an open source search tool for your workspace. I originally started off with Slack but quickly learned that Confluence search is a well documented problem: https://twitter.com/beajammingh/status/1273742155731791872?s... Sleuth solves this problem using semantic search to find relevant Confluence pages and Slack messages for your query. You can ask Sleuth questions about HR policies, technical documentation, product decisions, and more. Sleuth is open source and can be self-hosted, although there are dependencies on OpenAI and Pinecone (which will be swapped out for open-source alternatives for larger orgs with regulatory constraints). Feel free to reach out in our Slack group if you're interested in using Sleuth in your workspace: https://ift.tt/97Ac0nF... https://ift.tt/4zpFQHT https://ift.tt/DnKBbLh January 17, 2023 at 10:53PM

Show HN: VeloxDB Fast Object oriented DB for C# https://ift.tt/GMyR0Od

Show HN: VeloxDB Fast Object oriented DB for C# This is a project I have been working on with some friends for some time. We left our jobs in March to pursue it full-time, and now we have something to show. We built a database called VeloxDB (Velox means speed in Latin). VeloxDB is a fast, object-oriented, in-memory database for C# with an emphasis on correctness. Let me give a quick breakdown of all the terms involved: • "Fast": The whole database is built with performance in mind. We achieve 2.5 million ACID write transactions with an AWS c6a.8xlarge compute instance. • "Object-oriented": The DB offers an object-oriented interface, giving you an ORM-like experience. Your code is deployed within the database, reducing the overhead of communicating with the database to a minimum. • "In-memory": The entire dataset has to fit in memory, so if you have a 30GB database, you need 30GB of RAM. The data is still persisted on disk, so there is no data loss if the server crashes. • "For C#": The ORM API is primarily designed for C#, although it should work with any .NET language (F#/VB). • "Emphasis on correctness": The database is fully ACID, with no eventual consistency. The database is still in beta phase, and any feedback is very welcome! The source can be found at https://ift.tt/wSY6c9v . https://vlxdb.com/ January 16, 2023 at 02:32PM

Show HN: Free Online Course – Debugging Difficult Conversations As an engineer I get frustrated at other training courses that talk a lot of theory, but don't have a lot of practical advice and tools to actually help. So, I built an online self-paced training course on difficult conversations (think feedback, salary negotiation, etc) that I wanted to share with the community. I like to make my training courses more "algorithmic." A process you can follow to approach a Difficult Conversation, get in the right mindset to tackle it, and prepare what you need to that allows you to do it well. This course will teach you: - What Difficult Conversations are and what happens when you ignore them - Why having Difficult Conversations can be beneficial to you, your team, and your career - A framework (and accompanying worksheet) to help you prepare for Difficult Conversations https://ift.tt/N7i4sIK January 16, 2023 at 03:49AM

Show HN: Group accountability for atomic habits (iOS) https://ift.tt/wIqzd7Y

Show HN: Group accountability for atomic habits (iOS) I started this project by running 10-day group challenges on Whatsapp. The group was gathered via a Webflow landing page, Google forms, Zapier and a PayPal button (here’s what I posted on HN at that time - https://ift.tt/4rNBqG5 ). The WhatsApp challenges turned out to be a hit with over 85% checking in daily and 45% repaying to join multiple challenges. After having tried Streaks, Habitify, GTD, reminder apps, google calendar, Notion...etc—I was still having trouble staying consistent with my personal/wellness goals and habits. Methods from Atomic Habits by James Clear—are what worked best for me—but sticking to it alone was hard. For example, I had a daily push-up reminder on my google calendar that I ignored for almost a year. Fast forward, I’m now on day 120+ doing push-ups, meditation and waking up before 6am—after participating in group accountability challenges :) To see if we can scale it to help more people and potentially build a community-driven business—we just released an iOS app. Recap of how it works: - Join 10-30 day accountability challenges in small groups of 3-12 people - Commit a daily goal and check-in with the group on whether you didn’t or didn’t do it - Daily visual progress reports, reward credits/penalties and support from others helps everyone stay on track - Create and join private challenges with friends Would love to have you try it by joining a challenge—and see if could help you become the person you want be for 2023! https://ift.tt/XGOkspZ January 15, 2023 at 05:46PM

Show HN: Sleuth, open source workspace search in natural language https://ift.tt/NHbQ7FC

Show HN: Sleuth, open source workspace search in natural language Hey everyone, We know how hard it can be to ramp up and learn the ins and outs of a new company. - “Who should I talk to about customer onboarding?” - “What was that project the onboarding team shipped in June, that had a massive impact on step 3 completion rate?” Instead of asking someone the same question that’s been asked hundreds of times before, it’s more efficient to find answers in existing documents and past conversations. The problem is, this data is spread out across dozens of workplace apps, with search features that all work differently. That’s why we’ve created Sleuth, an open source library that allows you to search through your company’s entire history using natural language. It understands the intent of your question, not just the keywords. Here’s a demo: https://ift.tt/d9R5XBx You can fork our repo ( https://ift.tt/pu1Gveg ) and try it right now, or book a 15 min call ( https://ift.tt/YXD8bH3 ) with us to share your feedback. How does it work? Vector embeddings are generated for slack messages using OpenAI’s text-embedding-ada-002 model and stored in a Pinecone vector database for easy querying. How is this different from Glean? Glean is great, but we wanted to introduce a product that anyone can fork, use, and customize without ever talking to a sales team. Building in public makes for better products. What integrations do you support? Just Slack to start. What other integrations would you like to see? https://www.getsleuth.xyz/ January 13, 2023 at 01:10AM

Show HN: Fern, a language for defining REST APIs that compiles into OpenAPI https://ift.tt/cfxi2zg

Show HN: Fern, a language for defining REST APIs that compiles into OpenAPI Hi HN, this is Danny, Deep, and Zach. We built Fern after our previous ed tech startup failed. We were frustrated with how much time we spent writing “API code” instead of working on the actual product. We tried to use OpenAPI but we were underwhelmed - the generated code wasn’t idiomatic and it still required manual work (custom templates, scripts, manually publishing SDKs to registries). The Fern compiler takes your API as input and invokes generators that output things like: SDKs, server code, a Postman collection, and an OpenAPI spec. Some technical highlights about the compiler + generators: - The compiler (available as a CLI) handles syntactic + semantic validation. It also includes a linter that encodes best practices. If your API Definition compiles, you can have high confidence that the SDKs will generate correctly. - After all the parsing and validation, the compiler outputs an intermediate representation that gets handed off to the generators. This prevents each generator from re-implementing the same parsing and validation logic. - Each generator is implemented in the language it is targeting - e.g. the Python generators are written in Python, the TypeScript generators are written in TS. It makes the SDKs more idiomatic because every programming language generally has the best tooling/libraries for generating code in itself. We also think it’ll make community involvement + contribution easier. - The generators can output the code to disk, but also push the code to a Github repo and publish the SDK directly to registries (e.g. npm, Maven). We are looking for devs to use Fern for API development. If you have any feedback about the process, compiler, or the generated code, we’d love to hear it.

Show HN: Val Town – A Cloud Scripting Site https://ift.tt/CwXvGt0

Show HN: Val Town – A Cloud Scripting Site Hey HN! We're so excited to show you Val Town ( https://val.town )! A "val" is a JavaScript/TypeScript function or value that runs on our servers. We aim to get you from idea to running code in seconds: type code, run it, get its API endpoint, schedule it - all from the browser, in a couple keystrokes. We're a startup of 4 people, mostly in NYC. We've been working on this for 6 months and are eager for feedback from the HN community. Why do we need yet another online coding IDE? While researching devtools[1], I found myself wanting something halfway between Replit and Zapier: a tool that makes hosting, deploying, scheduling, and authenticating easy, but is first-and-foremost a programming tool. We added `console.email` to the runtime to make it incredibly easy to email yourself. We don't have npm imports yet, but we do have a low-friction system that treats every user as a namespace, so you can refer to `@me.foo + 1` or `@yourFriend.bar()` right in your code. There are a lot of thorny implications this newfangled import scheme creates, but also many joyous and carefree coding experiences! One of my favorite features is that we store every evaluation, up and down the callstack, including inputs, outputs, logs, etc, which has been an amazing aid to debugging. So far, Val Town is mostly used for what we're calling "programmatic notifications": query a data source for new items on an interval and email them to yourself. Get notified when users you "follow" post on Hacker News: https://ift.tt/p3Qtu75 Get notified when to close your window during fire season in SF: https://ift.tt/t7G46QN Get notified when there are new citations on a paper: https://ift.tt/W6vQRfc Subscribe to RSS feeds: https://ift.tt/ZBghrn9 A good place to get started would be forking one of those vals and modifying it to suit your needs. Some folks are using the tool in other ways, such as in webhook contexts, and we encourage those uses as well. We'd LOVE to pair-program with anyone looking to try out the tool and give feedback.

Show HN: We’re building a gaming console for the browser https://ift.tt/BNR30ix

Show HN: We’re building a gaming console for the browser hey all, We’re excited to share bash.gg - a way to play all games on your browser. Our mission is to enable you to play games, from any device, with your friends. We're planning on using a combination of WebGL (soon WebGPU) & pixel streaming to run any game. Our product is going viral within a few school districts, here’s what we’ve built. The Problem: Poor Experiences: Mobile gaming is limited by hardware. Most mobile games are spammy & focused on optimizing value extraction. Existing web games are junk. Expensive: For good games, you need a console or PC, costing $600 - $3k. Not Scalable: Consoles are sold at a loss & desktop computers are too expensive. Necessary hardware is increasing in size and cost. On the other hand, games continue to get more computationally expensive. bash.gg: Great Experiences: We’re bringing the best games from PC and console to your browser so you can play from any device instantly. Affordable: You don’t need expensive hardware, just a stable internet connection. Scalable: As games demand more resources, they’re run in the cloud. The games that don’t need all that power can run in a browser. TLDR: Consoles make it difficult to play with all of your friends. If your friend has Xbox, and you have Playstation - you might not be able to play together. Having games on the browser lets anyone play, by just clicking a link. Not only that, but you can chat and play, all in one place. In progress features: pixel streaming (quic + webcodecs), community features, live audio/text chat (should release within in 2 weeks) Excited to hear what you all think! https://bash.gg January 11, 2023 at 11:25PM

This was the trigger to write a small application that creates a map of your devices, their folders, and how each is shared. It is directly based on the configuration file of each device. The stable version[2] generates a HTML file you can render in a browser to show the map (based on mermaid.js[3]). I just released an experimental feature[4] that starts a web server which will dynamically create the map based on configurations shared by the devices. Binaries are available as well[5].

Show HN: Ecode – A minimalist and fast open-source code editor Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but it's a work in progress, and many features are still pending. Some minor hints on how to use it: Folders are used as project (and .gitignore is used to ignore files) The wheel icon on the top-right has all the options you need (Ctrl/Cmd + M to show). Some keybidings to navigate any project (navigation is keyboard driven): Ctrl/Cmd + K = Locate Files Ctrl/Cmd + Shift + F = Global Search Ctrl/Cmd + Number (Go to tab #) https://ift.tt/tugNRXS January 10, 2023 at 10:51AM

Show HN: PipeScore – FOSS Bagpipe Notation Software I've been working on some version of this since May 2019. It is a web app that allows writing out music for the Highland bagpipe. While it uses the same notation as normal music, bagpipe music tends to have a greater focus on gracenotes (embellishments). Most music software does not deal with this very well (e.g. MuseScore just displays a list of every single possible embellishment, of which there are hundreds [1]). PipeScore instead takes advantage of the fact that the form of many embellishments is dependent on the notes adjacent to it, allowing it to reduce the number of options down to just 13.

Show HN: Tortoise TTS as an at-cost open-source pay-per-second API Tortoise TTS is the best TTS available today. We built an open-source, at cost, pay per second API for it. The quality of intonation it generates is unparalleled, and we hope our at-cost API will make it easier for people to build on top! This allows folks to run via a single API call - it costs $0.03/query. The WAV file is downloadable, we apply no restrictions. We're open-sourcing all our work — we made Tortoise run 30% faster, and have more improvements coming. If you're keen to contribute we can help with ideas, pointers, compute and data; just DM us. Our fork with the improvements can be found at https://ift.tt/m95yDe2 . The deployment code can be found at https://ift.tt/eJ6oBQ0 . There are already great alternatives for using : i) @mdnest_r's awesome Huggingface Spaces, ii) original Google Colab, iii) host it yourself. Our work should accelerate those who need an API, don't want to spend time/$ hosting and need a scalable infra backing them. We're especially excited about combining text-to-speech with content generated from LLMs, and about how it fits into video creation tools. Tortoise in its current form is also inaccessible to non-technical users, which is why we are also providing a simple UI on top (also "at-cost"): https://tts.themetavoice.xyz To use, generate an API key on https://tts.themetavoice.xyz and call via POST request. Or use the web UI. Or run your own deployment. https://twitter.com/vatsal_aggarwal/status/1612536547248836608 January 10, 2023 at 01:35AM

Do not type commands unless I instruct you to do so. When I need to tell you something in English I will do so by putting text inside curly brackets {like this}. My first command is pwd. Then I told it to create a python script to do the conversion: {Create and write to the filesystem a python script called convert.py that takes a URL as its first argument. The URL is a chrome extension. The script then converts the extension to a Firefox extension and saves the result in a directory called "res". Make sure the script works with an actual URL to a chrome extension on the Chrome Webstore. It requires you to possibly download the extension first from the URL. Also make sure the generated Firefox extension meets all the requirements and the Chrome to Firefox conversion takes place for all assets in the extension, it includes the content scripts, etc. Only print done to the terminal here when finished.} Then ran it with this URL (URL to Google Translate Chrome ext): python convert.py "https://ift.tt/HTNhiOS" It actually created a zipped Firefox extension with the manifest file converted correctly, etc. January 9, 2023 at 09:50AM

Show HN: Have voice-only virtual coffees with fellow HN'ers https://news.ycombinator.com/item?id=34296783

Show HN: Have voice-only virtual coffees with fellow HN'ers I'm running several voice-only virtual coffee events on the Discord server in the URL, only for today. The rules are pretty simple: 1. Wait for the "event" to start (see times at the end) 2. If there are no tables with 1 participant, join any one. 3. If there is a table with 1 participant, join that one. 4. When the event ends, all the voice channels are deleted and you have to wait till the next event starts. I initially wanted to build my own web app but then I realised it would be so much easier to just leverage Discord's infrastructure. I also built a bot in a couple hundred lines of Go code (love the language!) to bulk create/delete voice channels. I intentionally left it super basic to validate if there's a need. I personally would love to have virtual networking events, but then again I know I'm somewhat odd as I come from a sales background. If you're interested/want to take part in more of these events, check out my profile where I have some contact options. Anyway, here's the times (each lasts 1 hour): - 8 AM GMT / 1.30 PM IST / 12 AM PST - 11 AM GMT / 4.30 PM IST / 3 AM PST - 2 PM GMT / 7.30 PM IST / 6 AM PST - 5 PM GMT / 10.30 PM IST / 9 AM PST - 8 PM GMT / 1.30 AM IST / 12 PM PST - 11 PM GMT / 4.30 AM IST / 3 PM PST https://ift.tt/rpbksA3 January 8, 2023 at 12:29PM

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ https://ift.tt/Rmk0dy5

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ Hey HN: Kaveh here, the founder of https://www.usage.ai/ We help companies drive down AWS EC2 spend by buying and selling 3-year no-upfront reserved instances. Why? Because there's almost no liquidity on the AWS EC2 RI Marketplace and it can take a while, if at all, to sell an RI if you need to stop using one. Previous to founding Usage, I worked at JPMorgan Chase as a summer analyst. Here's how it works: We are typically brought in by a DevOps manager to cut AWS EC2 costs. The app is entirely self-service and the savings are generated automatically, typically we do this live on a call. On average, we reduce AWS EC2 spend by 50% for 5 minutes of work. To reduce by 50%+, we've built a pool of reserved instances that's shared across our pool of customers. When a customer scales up their EC2s, Usage buys RIs. When a customer scales down their EC2s, Usage sells RIs. At this point, we've saved companies tens of millions of dollars in spend and have a lot of liquidity, so we take on very little risk. We make money off of a 20% Savings Fee. Happy to chat directly kaveh@usage.ai Have you experienced any issues with managing your company or organization's AWS expenses? We'd love to hear your feedback and ideas! January 7, 2023 at 09:15AM

Show HN: ACOS: Build and share competitive turn-based browser games Hi everyone, This is a little tech demo I've been working on the past 2 years. It's been up for 1 year now, and has since had a few major updates. I have a soft spot for games with ranking systems, and I wanted an easy way for developers to create games with the competitive element abstracted away. The current games are built with ReactJS, so it's pretty easy to onboard if you are a web developer. All games developed for ACOS come with these features: - Real-time turn-based for browser - Simulator for game development - Client / Server architecture - Easy multiplayer with simple JSON game state update - Single player, Team-based, Battle Royale, and Free-for-all games supported - Matchmaking for Rank / Casual play - Room Scoreboard - Game Replays of every match - Error Logs - Global Rankings - Global Top Scores - GitHub Integration with acosgames organization - Discord Integration for matchmaking / game events - Simple deployment and version management It's a ridiculous endeavor, but I'd like to invite the world to my playground and help me drive features and technology forward. I may allow AI bot battles in the future against any of the hosted games, but I will prioritize based on the will of the people. Read our documentation at https://sdk.acos.games/ Hope you enjoy it! https://acos.games/ January 7, 2023 at 05:45AM

Show HN: I spent 2 years building Tablane as a 17-year-old https://ift.tt/kvQrG2F

Show HN: I spent 2 years building Tablane as a 17-year-old Hi HN community, I'm Marcus, a 17-year-old Software Engineer from Germany. For the past two years I've been working on Tablane [0]( https://ift.tt/COz1ej6 ) a task/project management tool, with features like: - Collaborative Editing (google docs) - Optimistic updates with RTK Query - Realtime sync with Socket.io - An awesome design Let me know what you think! Ask me anything! How I got here: 2020: I was developing a TTT [1] (Trouble in Terrorist Town) plugin for my minecraft server, when I started to require a project management tool to keep track of the features I wanted to implement, originally I used a text file, but after some time I started using products like ClickUp and Monday. But not long after I hit several paywalls for features that I wanted to use (Custom Status, Limited Number of Boards, ...) Soon after Tablane (originally task-board) was born. I started building the website using plain HTML, then found out about React and completed Colt Steele's "Web Developer Bootcamp" [2] and "The Modern React Bootcamp" [3] and started re-writing Tablane in React, and started adding feature after feature. Now I am about to finish Highschool and originally I thought about applying to college and spending another 3-5 years there, but after the positive feedback I got on a three month internship I did at ContentPepper, and seeing how my own projects developed, I decided to look for open Developer positions, to work with a team of experienced developers so I can learn even faster.

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books https://ift.tt/3BZNyhY

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books Hi HN, We’re Elizabeth, Catalin, and Tom - the founders of Ello ( https://ift.tt/7LixqFe ). Ello is an AI-powered app that mimics the one-on-one interaction of a reading tutor by listening to, encouraging, and coaching kids grade K-3 as they read out loud from a real book. We posted on HN back in 2020 when we launched Trustle, a company designed to pair families with dedicated experts in child development. We learned from that experience that parents don’t want a consultant, but they do want actual help with specific challenges—one of the biggest being reading. Prior to COVID, 65% of 4th graders in the U.S. were reading behind level. The most recent National Assessment of Educational Progress report revealed that reading levels have dropped even further, to the lowest level since 1992. These disheartening statistics reinforce something we learned during our time at Trustle—of all the pain points parents face in raising children, reading can often be one of the most critical yet most difficult to address, especially if the child doesn’t like to read. In an effort to help reverse this trend, we used advances in speech recognition - driven by self-supervised learning - to create a virtual experience designed to provide effective reading support. It's no substitute for attention and coaching from a caring adult, which is obviously what kids really need, but unfortunately that is not always available. If every child had consistent access to 1:1 reading support and every parent or caregiver had the time, language skills, and confidence to help their children learn to read with no outside assistance, then there would not be a need for a technical solution. Unfortunately, we know not every child has this access, and many parents are looking for extra support. That's why we've built Ello. If you look at a great teacher or parent working with a child, they are talking to each other. Ello uses a speech recognition model that listens to what a child is saying and provides the appropriate phonics based coaching, as well as commentary and help. As a child reads across the page of a physical book, the Ello app tracks the child’s progress and picks up when they miss a word or get a word wrong and then steps in just like a good reading coach would. One criticism that we’ve heard since launching is that we are trying to replace the sacred role of a parent teaching their child to read. We say, “Not at all!”. Ello can serve as a resource for every type of parent without being a “replacement”, which is impossible in any case. We’ve had most success with children who are reluctant readers. Ello provides a fun environment to practice reading without the pressure of an adult watching you. We’ve seen kids who flat out refuse to read start to enjoy reading in a short period of time. We are highly privacy oriented; unlike most apps relying on speech tracking we can work completely on device with no internet and no audio data shared back with us. We launched in early in 2022 and have come a long way since then. The model works like this: we mail customers five books and a prepaid return shipping label every month. At the end of the month you mail the books back or keep as many as you want for an additional $5 apiece, and then we mail you next month’s box. Our reading specialists help determine the appropriate reading level for every child and make sure that we are sending books to match. Right now we support roughly K through 3rd grade, although Ello can be effective for some Pre-K kids as well. We know there are many parents on HN, including those with young children. We would love to hear about your experiences and needs around your children’s reading journeys and your perspective on how something like Ello might help. Or, if you’re in the US, give us a try - you can get a free month with code ellohacker. And of course we welcome any feedback, questions, and ideas!

Show HN: Banger–A Firefox extension to extend DDG's bangs https://ift.tt/CBFd6P0

Show HN: Banger–A Firefox extension to extend DDG's bangs Hello HN! I made this Firefox extension to extend upon DuckDuckGo's idea of bangs (check https://ift.tt/36utmPi if you aren't familiar with them) and also allow the use of any search engine with them. I found DuckDuckGo's bangs fascinating, but was disappointed by how little search engines inherit that feature. And on top of it, DuckDuckGo has the "!" bang that jumps to the first search result but other search engines offering bangs like Brave Search, searx, You.com don't seem to have that. I also thought that the "!" bang could be extended with the ability to jump to the first search result of a specific site, so I added the "!!" bangs in my extension that allow you to do just that (e.g. typing "!!mdn flatMap" will bring up the MDN page for flatMap). I also added a bunch of extra features like the ability to add custom bangs, ability to search in a search engine with the "site:" parameter using "!@r" (r for Reddit), or "!ddg@r" (specify any other bang as the search engine to use), and the ability to chain multiple bangs together with ";" to open them up in different tabs; it also allows you to use multiple "site:" parameters combined with the OR ("|") operator with "," (e.g. "!@r,yt"). Feel free to mix and match! Also, for those who use it, it supports sync. There's also an option to import/export any settings including custom bangs. I've also added custom handling to fix a few bangs which are usually broken such as "!archived" and "!imgops" (They require unescaped URL as part of the path. However, DDG and other search engines always escape the URL. Banger only escapes the URL if it's part of an URL parameter). I've been working on it for around 2 months now, and I'm pretty satisfied with the result so far. Let me know if you have any comments/feature suggestions/bug reports/anything else! https://ift.tt/e0liEnm January 2, 2023 at 11:18AM

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
