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.

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/ed82M3u September 30, 2023 at 12:29PM

Show HN: Launching a new home-grown embedding LLM for RAG Hi HN! Vectara is a "batteries included" retrieval augmented generation platform. You can upload your rich text documents like PDFs, HTML pages, word docs, etc, or semi-structured JSON and Vectara handles the text and metadata extraction, segmentation, vector embedding, and vector storage, and keyword storage. You can ask a question or perform a search in the UI or via our APIs and Vectara will automatically handle the vectorization, structured metadata filtering, vector+keyword retrieval, hybrid blending, and generative summarization of the results. We're focusing on building and operationalizing the complex infrastructure for vector storage, hybrid retrieval, and generative summarization so you can use fairly high-level APIs and focus on building your own applications. We know that retrieval accuracy is incredibly important for RAG: garbage in, garbage out. We've seen a lot of projects not spend enough time o...

I want to create a good software and I don't want to make rich by charging on things running on your own resources (your computer, your server, your cloud,...). So basically, RFSH will be free-forever for usage. You put a .csv file, a bash script as a template file, RFSH will take care the rest, then you will receive the clearly reports after all.

Show HN: Using LLMs and Embeddings to classify application errors Hi Hacker News! We’re Vadim and Chris from Highlight.io [1]. We do web app monitoring and are working on using LLMs/embeddings to add new functionality to our error monitoring product. Given that there’s a lot of founders/engineers using LLMs in their products, we figured we’d share how we built the new functionality, their impact on our workflows, and how you can try it out. Our goal was to build two features: (1) tagging errors (e.g. deeming an error as “authentication error” or a “database error”); and (2) grouping similar errors together (e.g. two errors that have a different stacktrace and body, but are semantically not very different). Each of these rely heavily on comparing text across our application. After some experimentation with the OpenAI embeddings API [3], we went ahead and hosted a private model instance of thenlper/gte-large (an open-source MIT licensed model), which is a 1024-dimension model running on ...

Show HN: I recorded nature sounds for a year, then released an ambient sound app There are lots of ambient sound apps on the App Store, but they all seem to be paywalled. I thought I should make one where all the content was free. I bought a secondhand professional audio recorder, then took it to national parks in Australia and Germany, in case I heard anything interesting. It was a bit of a learning experience, but I now have a library of half a dozen passable recordings. The biggest problem was noise pollution: humans are noisy and everywhere; I never noticed until I started listening carefully for background noise. Traffic and building noise carries for huge distances. I wrapped all the sounds up in a swiftUI interface, built around a curved video carousel. I wanted to pay special attention to vision impaired users, so it all has VoiceOver support, and extra UI elements that can be turned on for vision impaired users. It's free on the App Store if you want to take a look. https:...

Show HN: I made a site to find Reactjs jobs This is an experimental project. I see that there is no decent place to find ReactJS jobs. So, I took the liberty of creating it myself today. I am little surprised that no job board has been built for Reactjs jobs yet (Vuejs has one), may be there is some good reason for it. Let's see. The site is still very basic. I wanted to keep the MVP simple and check if the community loves it. First I scraped some results from Google SERP and put them on a JSON file and then made a Puppeteer script to visit each page and scrape the necessary job details. Here is the stack: Nextjs for the frontend and JSON as the database. I'll dedicate my time to improve the project if it proved to be a useful site among React devs. Thanks. https://ift.tt/aTmL7vw September 23, 2023 at 04:13PM

If it’s a valid midi it probably plays. Since releasing, I did add a subscription for classical music - on a theory that most normal users don’t know what a midi file is. It changed about a month ago from an up front price to in app purchases and/or a subscription - which has absolutely tanked revenue so far - but maybe it will pick up Would love to hear your thoughts and if you have any suggestions! https://ift.tt/huSa1Tf September 22, 2023 at 02:02PM

I was therefore inclined to find a solution that would help me to systematically improve my breathing pace, but since I couldn't find anything related to it, I therefore decided to solve it myself. Being a designer while also having skills of a full-stack developer, I decided to learn Swift and use Apple Watch to design one. In essence, the app is rather similar to how Strava works on Apple Watch: you start your workout session, go through with it, and then have it saved for further analysis. The real difference is that you also set your breathing pace, which will translate your heart rate to breath rate and give relevant haptic cues when to breath in and out. Since I had to build a sampler to WatchOS, I also experimented with trying the app to generate background music that would be synced to...

Show HN: Graphite – Stacked Diffs on GitHub TLDR; Graphite enables a git workflow called “stacking” - the fastest way to develop and ship code, which many large tech companies have been using for years. Graphite makes stacking available to anyone with a GitHub account. Hi HN! I’m Tomas, co-founder of graphite.dev, and today we’re launching Graphite after almost two years of development in closed beta. [1] Graphite started as an internal solution to our own problem. When we (engineers from Meta, Google and Airbnb) left our previous roles, we lost access to the internal code review tools we loved. So we built our own. Graphite is how the fastest developers ship code - it’s a developer tool that allows you to create smaller pull requests, stay unblocked, and ship faster with “stacking” (creating a set of dependent pull requests). Stacking [2] allows developers to break up large pull requests (PRs) into smaller ones that can be reviewed & merged independently, while keeping ongoing dev...

So I made the app that I can enjoy when writing posts on my Astro-powered blog. It's been saving me a ton of time already. I don't need to: 1. Edit in iA writer then paste into VS Code. 2. Google YAML date format. 3. Generate Unix timestamps to prefix new files with. 4. Copy paste images and write down their URLs manually. 5. Peek at collection schema to remember which frontmatter fields am I supposed to fill out. Because it's exclusively made for Astro, it can integrate deeply with it and support Astro-specific features and conventions, like where images need to be stored or how to reference entries from other collections in the frontmatter.

Show HN: LLM Powered Keyboard [video] Hey HN, I'm excited to share Taikoboard, a mechanical keyboard with LLM powered autocomplete. I made this keyboard for myself so I could use LLM-powered autocomplete in apps that didn't have this feature. Although more apps have started integrating LLMs, there's a large number of software tools that don't support this. Taikoboard bridges that gap, making the AI autocomplete experience universal. Would love to hear feedback, answer questions, or discuss potential use cases you see for Taikoboard. https://www.youtube.com/watch?v=BbMSWZKrrcI September 18, 2023 at 01:14PM

Show HN: Me and my buddy made $20 with a Stripe link and a Tweet Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The short answer is no, We gained some initial momentum but we can't call it a business yet, not until we are starting to get recurring revenue. What next? We created a notion file with multiple marketing channels we plan to test out and see which one is the best. We also created a list full of websites to submit our product and we are tr...

Show HN: ARA Records Ansible and makes it easier to understand and troubleshoot Hey HN, long time lurker here. I humbly present ara which is a project I created back at Red Hat in 2016 (before AWX was open source) to make my life easier working with distributed and large scale Ansible playbooks.

Show HN: I made a browser extension for building your own custom HN themes Hi HN! I’ve spent the last few weeks writing a browser extension that lets users write their own HN themes using Handlebars and CSS. It works by converting the current Hacker News page’s content into an object that is made available to the user-defined Handlebars templates. There is a built-in code editor that makes writing themes super easy and you can see changes in real-time. If you don’t want to write a theme from scratch, there are premade themes available or you may import one made by somebody else. It is shipped with Bootstrap so you can get pretty far without needing to write a lot of custom CSS. Material icons are also included so your themes get iconography out of the box. Any theme can be toggled into dark mode with a single click. It is open-sourced under the MIT license so feel free to use any of the code in the linked repo[0]. Additionally, I’ve put together a short demo video on YouTube[1]. If you...

Nue JS supports server-side rendering (SSR), reactive components, and "isomorphic" combinations. It takes inspiration from Vue 2.0 and Riot.js. (I'm actually the original author of Riot). 2. Nue ecosystem: https://ift.tt/C7zpH25 — This is the ultimate goal and once all the sub-projects are finished, Nue will be a serious alternative to things like Vite, Next.js, and Astro.

Show HN: Eesel AI – ChatGPT over company knowledge, without APIs Hey everyone! I'm Amogh and I've built eesel AI. It's like ChatGPT over your company knowledge (yet another one?!) - but with a twist. Instead of relying on APIs to integrate with your applications, you simply use our browser extension to add relevant pages as "Knowledge". Then, you can chat over that. Whether it's a Google Doc, Notion page, help docs, or any other website - you can add it as "Knowledge" and chat with it. You don't need to grant full API access to your work apps. For public pages, we have a crawler. For private pages, we use the extension, but we're exploring a crawler for that as well. While bypassing APIs might seem unusual, we see it as an interesting approach to create a universal AI teammate. One that could, in the future, operate autonomously, accessing your applications just as you would - retrieving information and even taking actions. That's the vis...

Show HN: ChatGPT History Explorer Hey HN, As a heavy ChatGPT user, I often want to explore my chat history, look for things I've already asked, keep favorite chats, and much more. ChatGPT doesn't even offer search capability (except in mobile version). So I decided to build one myself. It runs locally, so no sensitive data leaks. You only need to export your ChatGPT conversations, and put it in the `data` folder. Optionally setup OpenAI API key and it will create embeddings for semantic search. *Important* - it's not a desktop app (at least, not yet) - it's a python code with a browser interface that I've only tested on MacOS so far. Minimal dev skills are required to set it up. Current functionality: - Github-style activity graph and some other statistics - Browse and read your conversations - Quick filters by conversation title and time period - Search (semantic and simple "strict") - Add chats to favorites - Open conversations on the ChatGPT site to con...

Show HN: Labor Day Fun Project, Find Reddit Comments to Promote Your Business For Labor Day I decided to play with OpenAI APIs and try to ship something (a prototype, a blog post, anything really). Whenever I launched a side project (e.g: https://ift.tt/g4hvSFi , https://ff.bitlet.org/ ) I realized how bad I am at marketing or even at mentioning my the project to friends/social. I noticed that most of the traffic we got was coming from reddit/HN comments we made where it was reasonable to mention the sideproject/business. Given that, I tried to use OpenAI APIs to do exactly that, given a business/project description, and a list of subreddits, monitor all comments and pick the ones where it makes sense to mention the business/project. While I had the project done in the labor day weekend, I decided to productionize it a bit (really just add a login system and a payment link to cover OpenAI costs) last weekend. If anyone is interested in giving a shot, you can play with it at https://sp....

I realized that I will die without hearing every song that I will fall in love with. So many of my all-time favorite songs I randomly have heard at a club, coffee shop, traveling, walking by a store, etc. There is a high chance that I would have never heard those songs. Loopy aims to fix this. You can post your all-time favorite songs. If someone else love this song, there is a chance you will too :).

Obviously, running sequentially through a list of ports until I find one I have not already allocated does not perform very well.
