Show HN: Noisy Nest Free white/pink/brown noise generator https://ift.tt/yIk4W62

Show HN: Noisy Nest Free white/pink/brown noise generator Hi All, i was playing around with GPT-4 today, and threw together a simple noise generator. It can play pink, brown, and white noise indefinitely. I spent maybe an hour creating this. It's quite amazing what you can do with such little time with AI. Let me know if you think of any features to add, and i'll consider adding them to make this more useful. https://ift.tt/7Ef6Yop October 1, 2023 at 02:40AM

Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community https://ift.tt/NRfInLm

Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community Hey friends! We have built an app for getting insights about your favorite GitHub community using large language models. The app uses LLMs to analyze the GitHub profiles of users who have starred the repository, capturing key details like the topics they are interested in. It takes screenshots of the stargazer's GitHub webpage, extracts text using an OCR model, and extracts insights embedded in the extracted text using LLMs. This app is inspired by the “original” Stargazers app written by Spencer Kimball (CEO of CockroachDB). While the original app exclusively used the GitHub API, this LLM-powered app built using EvaDB additionally extracts insights from unstructured data obtained from the stargazers’ webpages. Our analysis of the fast-growing GPT4All community showed that the majority of the stargazers are proficient in Python and JavaScript, and 43% of them are interested in Web Development. Web developers love open-source LLMs! We found that directly using GPT-4 to generate the “golden” table is super expensive — costing $60 to process the information of 1000 stargazers. To maintain accuracy while also reducing cost, we set up an LLM model cascade in a SQL query, running GPT-3.5 before GPT-4, that lowers the cost to $5.5 for analyzing 1000 GitHub stargazers. We’ve been working on this app for a month now and are excited to open source it today :) Some useful links: * Blog Post - https://ift.tt/9efhlxp... * GitHub Repository - https://ift.tt/61Obgif * EvaDB - https://ift.tt/agJGDn8 Please let us know what you think!

Show HN: A tool to help optimise your system prompt https://ift.tt/IyTmd2A

Show HN: A tool to help optimise your system prompt I needed a way to choose between different system prompts for a ChatGPT-powered side project, so I built Prompt Picker. The basic idea is: specify some candidate system prompts and a few example user inputs, and then run a blind experiment where you choose the better output from pairs of generations. If you need to optimise the system prompt for your LLM-powered application, give it a try and let me know what you think. https://ift.tt/DfZ2kjs September 30, 2023 at 04:59PM

Show HN: Dolce – Get notified if something (bad) happens to your containers https://ift.tt/qES5yZV

Show HN: Dolce – Get notified if something (bad) happens to your containers Hi HN, while I was on vacation this year the shop of my wife was suddenly down and we only noticed once the emails of customers rolled in. After fixing it on my phone I thought there has to be a better way to notice when your docker container die or are in a restart loop for whatever reason. Now I know there are lots of tools like healthcheck.io and monocker, however none seemed to match my simple use case of getting notified _via email_ when the running– or health-status of any docker container changes. So I did what every SE would do in that case and hacked another solution but this one is mine :). I also always wanted to do a project with deno and get up to speed on typescript. This was also a great reason to finally look into using GitHub Actions to automate some of the tedious tasks. Fun fact: After reading on here about Deno Queues, I rewrote the message buffering and backoff completely and could greatly simplify the code. TL;DR - What is this: Get notification via - EMail (BYOSMTP) - Discord - Telegram if any (or only selected) containers on your host die or change their health status. I also tried to handle unexpected restarts of the container the tool is running in gracefully without loosing any events that happened before and even while the service was down. To make sure you are not spammed by notifications if a container goes into a restart loop, there is also a configurable exponential backoff function. I tried to make using the tool as easy as possible (by getting inspired on how monocker is set up). I would love to get some feedback and hear what you think (also if I just missed the perfect tool for the job: let me know, however the journey was quite fun). https://ift.tt/tpN43nW September 29, 2023 at 11:11PM

Show HN: Ultra-Realistic Generative Fill with AI and 3D https://ift.tt/UjIyoYF

Show HN: Ultra-Realistic Generative Fill with AI and 3D Hey all, You've probably seen projects that add objects to an image from a style or text prompt, like InteriorAI (levelsio) and Adobe Firefly. The prevalent issue with these diffusion-based inpainting approaches is that they don't yet have great conditioning on lighting, perspective, and structure. You'll often get incorrect or generic shadows; warped-looking objects; and distorted backgrounds. ### What is Fill 3D? Fill 3D is an exploration on doing generative fill in 3D to render ultra-realistic results that harmonize with the background image, using industry-standard path tracing, akin to compositing in Hollywood movies. ### How does it work? 1. Deproject: First, deproject an image to a 3D shell using both geometric and photometric cues from the input image. 2. Place: Draw rectangles and describe what you want in them, akin to Photoshop's Generative Fill feature. 3. Render: Use good ol' path tracing to render ultra-realistic results. ### Why Fill 3D? + The results are insanely realistic (see video in the github repo, or on the website). + Fast enough: Currently, generations take 40-80 seconds. Diffusion takes ~10seconds, so we're slower, but for the level of realism, it's pretty good. + Potential applications: I'm thinking of virtual staging in real estate media, what do you think? ### Check it out at https://fill3d.ai + There's API access! :D + Right now, you need an image of an empty room. Will loosen this restriction over time. Fill 3D is built on Function ( https://fxn.ai ). With Function, I can run the Python functions that do the steps above on powerful GPUs with only code (no Dockerfile, YAML, k8s, etc), and invoke them from just about anywhere. I'm the founder of fxn. ### Tell me what you think!! PS: This is my first Show HN, so please be nice :) https://ift.tt/A1mzDdj September 29, 2023 at 02:11AM

Show HN: Use ChatGPT with Apple Shortcuts https://ift.tt/5gm0GC3

Show HN: Use ChatGPT with Apple Shortcuts This project was born from my passion for every Apple product and the entire ecosystem, along with the power of ChatGPT. I was tired of copy-pasting and switching between apps on my Mac or iPhone, so I had this crazy idea to bring ChatGPT into every app that I use. This was possible only with the Apple Shortcuts app. Very few people know about its power and potential, so I took this chance and built COPILOT. https://meetcopilot.app But I also loved the idea of AI agents using various tools so much that I leveraged OpenAI's function-calling feature to accomplish that. Now, no matter what app I am using on my iPhone or Mac, the selected text or the current webpage from Safari will be passed automatically to COPILOT. Then I just ask it whatever I need and watch until it reaches the goal autonomously. There was also another problem with ChatGPT - the knowledge cutoff. So I also integrated Google search and web scraping into it. Now, whenever my request needs real-time information, like what is the latest version of macOS, it will use these tools to gather the data and then give me the correct response. Being an app built with Apple Shortcuts, all its "code", called actions, is actually open-source. I'm selling a Premium version of it to earn some revenue for my time. I would love to hear all your thoughts on it! Thank you so much! https://ift.tt/wIpT680 September 27, 2023 at 02:07PM

Show HN: The Tomb of Ramesses I in the Valley of the Kings Hey all, I’m coding up a new tour system for my 3d Egyptian work. After the last feedback, I focused on building more interactive content and fx into the guided tours with sound and telling the mythology in the wall art. I’d love feedback with the new version – this is built with vanilla Three.js and footage captured on my iPhone 12. For various fx, I coded many of my own shaders based on work by https://twitter.com/akella and others on ShaderToy, so I’m keen to test on more devices. As the hacker, so the (ancient) painter. https://ift.tt/1CExWQN September 26, 2023 at 06:34PM
