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 develope

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

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

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

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

Show HN: A simple API/CLI for scheduling HTTP requests Hi HN! This is something I've been tinkering on for the past couple months. It's basically just an API/CLI for scheduling delayed or recurring jobs as HTTP requests. I initially built it as a personal tool to save myself a bit of time on little side projects where I've needed scheduled/recurring alerts, but decided it could be a good opportunity to practice building out a nice landing page [0] and documentation [1]. And who knows, maybe someone else will find it useful ¯\_(ツ)_/¯ The tool relies heavily on Elixir's Oban [2] library for managing jobs, and Mintlify [3] for documentation. I also shamelessly stole most of the frontend design from Resend [4] because I'm a fan of the aesthetic and thought it would be good for my design chops to use their design as a guide. I also discovered Radix [5] UI while working on this, which ended up being immensely helpful for moving quickly on the frontend. Anyways, I almost c

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

Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering implementation is based on the Unreal physically based rendering (PBR) approach. The physics engine was built from the ground up to handle both 2D and 3D physics together. The scripting language was also built in house to be a type safe language that binds to C++ objects and facilitates auto-complete (try it in editor!) This particular fork by Raverie builds

Show HN: MyGPT a toy LLM which can be trained on Project Gutenberg and dad jokes My puny version of ChatGPT. This was based on the excellent LLM lecture series by Andrej Karpathy: https://www.youtube.com/watch?v=kCc8FmEb1nY The main points of differentiation are that my version is token-based (tiktoken) with code to load up multiple text files as a trining set. Plus, it has a minimal server which is a drop-in replacement for the OpenAI REST API. So you can train the default tiny 15M parameter model, and use that in your projects instead of ChatGPT. I trained it on 20Mb of Project Gutenberg encyclopaedias, then fine-tuned it on 120 dad jokes, to get a Q: A: prompt format. This model + training set is so small that the results are basically a joke; it's for entertainment purposes only. The code is also very rough, and the server only has the minimum functionality filled in. I embodied this model in my talking LLM-driven hexapod robot, and it could give very silly answers to spoken qu

It pulls in all the log lines, enriches them with useful metadata like the IP address of the instance, the machine name, the log source, the datetime, etc. and stores it all in SQlite, which it then exposes to a very convenient web interface using Datasette. I put it in a cronjob and it's infinitely better (at least for my purposes) than Splunk, which is just a total nightmare to use, and can be customized super easily and quickly. My coworkers all prefer it to Splunk as well. And oh yeah, it's totally free instead of costing my company

Dittofeed is an open source (MIT licensed) alternative to platforms like customer.io, mailchimp, klaviyo, iterable etc. Self-hosting is particularly useful if you: - Want to evaluate Dittofeed without a long-term commitment - Prefer fixed, non-volume based pricing models - Aim to keep all personally identifiable information within your own infrastructure In this version, we introduced 'Dittofeed Lite,' which merges the dashboard, API, and worker services, simplifying deployment, along with providing an easy auth setup. We've also configured a 1-Click Render deployment. The Render setup comes at a fixed cost of $39/month. However, by using alternative hosting solutions for the Postgres and ClickHouse instances (neon, clickhouse cloud), the monthly costs can be reduced to under $20. We personally

Show HN: Pendable - high performance email sending with Amazon SES Hi HN, Today we announce Pendable (Pendable.io), which is a production-grade email sending platform using Amazon SES. Pendble does parallelized email sending, dynamic priority queues, scheduled future delivery, email events, active throttling based on bounces and complaints, spam domain filtering, email logs and resend options, all using your existing Amazon SES setup. To get started, use our API instead of SES and start routing your emails through Pendable. In our day job, we develop bespoke custom loyalty solutions for enterprise customers and have been doing that over a decade. We use SES extensively as it is cost-effective and robust but we found a lot of gaps and decided to build the features instead of moving to solutions like SendGrid or MailChimp. With Pendable, you can continue using your SES account to send emails, while Pendable makes it robust and high-performant. Furthermore, we provide an easy to use monit

Show HN: Collaborative Lisp Coding on Discord This is a Discord bot I made, which lets you write and evaluate Lisp code in collaborative sessions on Discord.

I'd be happy to get your feedback, especially on how to improve the deletion mechanism (maybe make deletion sexpr-based?). I've tried to make the README detailed enough so that it's easy to make some changes and run your own version. https://ift.tt/N9a4Q3G September 19, 2023 at 12:22AM

Show HN: macOS GUI for running LLMs locally Hello HN, I've been working on this project for a while, and it has been in an "open" beta for some time. I finally believe it's ready for its first release. I hope you like it. Here are some potential questions that may arise: 1. How does it compare to LM Studio? It's likely that if you're already using LM Studio, you'll continue to do so. This project is designed to be more user-friendly. 2. Is it open-source? No, it is not. 3. Does it use any open-source libraries? Yes, it uses llama.cpp and a few others, as indicated in the license information included with the application. 4. Why is not using electronjs? Two reasons, I wanted total control over the whole tech-stack and second, I wanted to be able to send this to my friends over iMessage. 5. Does it support Intel macs? It should, but I couldn't test it. 6. Does it support older macOS? 12.6 is the lowest version at the moment. 7. Is XXX a bug? Probably :)

Show HN: A murder mystery game built on an open-source gen-AI agent framework Hey HN, Michael and Scott here. We’re open-sourcing an interactive murder mystery featuring LLM-driven character agents. Solve the mystery by finding clues, taking notes, and interrogating agents. They all have distinct motives, personality, and can impact the game in different ways (attacking you, running away, etc). Try it out, it’s pretty fun! We’re also open-sourcing the framework that we used to make and refine the agents. The goal is to create an intuitive interface for storytellers to create, debug, and test game agents. We then take those game agents and expose an API beyond just chat - such as actions, player guardrails, emotional queries, etc. We’re not done yet - there are a lot more features coming on the way: scenario-based agent evals, agent-storyline consistency management, automatic agent generation, etc. We would love to hear your feedback. Thanks! [0] https://ift.tt/xe3fcWL [1] https://ift.t

Show HN: HyperDX – open-source dev-friendly Datadog alternative Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://ift.tt/86ejBnZ Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously leading dev experience at LogDNA/Mezmo, we knew there were gaps in the existing tools we were used to using. Our previous stack of tools like Bugsnag, LogRocket, and Cloudwatch required us to switch between different tools, correlate timestamps (UTC? local?), and manually cross-check IDs to piece together what was actually happening. This often made meant sm

Show HN: Live Train Webcams Our son is really into trains. He was home sick a few weeks ago and we found that there are several YouTube channels that have live video feeds from various train stations or railway clubs around the US. He really liked it, but he kept wanting to know when the next train was going to show up so he could see it. I built this small website at https://ift.tt/DiHG6RZ which shows the time to the next train (Pacific time) and will automatically rotate channels to find the next train. It uses the Amtrak live train data today. In the future I might add other agencies, since a few of these stations do have more than one agency that services them and there are also some international stations I found feeds for. Hope this may be of some use for those of you with your own railfans in your life :) https://ift.tt/DiHG6RZ September 18, 2023 at 04:03AM

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: 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

It's like React/Vue core, but there are no hooks, effects, props, or other unusual abstractions on your way. Know the basics of HTML, CSS, and JavaScript and you are good to go.

Show HN: A vector database with semantic SQL-like filtering Hi HN! It’s always bothered me that there’s no real equivalent of SQL WHERE for vector content. Filtering is one of the cornerstones of a modern database — but vector DBs only support either top-k sort, which is only useful for fuzzy search, or metadata filtering, which isn’t semantic. I’ve found myself wanting all the results matching my semantic query, not just k! Aside from data analysis, it's relevant if you’re trying to do any LLM reasoning: you don’t make good decisions or reach good conclusions by considering a small subset of information. So, we’ve designed a filtering primitive on top of vectors and assembled a demo on customer reviews from Trustpilot, Yelp, App Store, etc. You can select any brand/restaurant/app, and slice the review data however you want. The filter should find all matching documents, not just the top-k. Check it out at https://ift.tt/84dMtZm ! Not super optimized yet, and really just an explora

I understand a human date can't be replaced but certainly we could help to an extent. NOTE - THIS IS NOT AN AI GIRLFRIEND. This is how it works: 1. Swipe from profiles of the opposite gender and then you're matched with someone. 2. Start an engaging chat & earn or lose points based on your charm (or lack thereof). 3. Simultaneously get reply suggestions to navigate the conversation. 4. Receive a final verdict: Would they like to go out on a date with you? And the best part? Those points are

Show HN: Victor, a browser-optimized vector database written in Rust Hey HN, My friend Sam and I were bored one weekend, and wanted to make something self-contained but still useful. We ended up with Victor [0], a vector database designed to run in the browser. It’s written in Rust, which gives us access to things like super-fast and compact serialization and deserialization, but it’s compiled to WASM and uses web-sys to interact with the browser’s JS APIs to write the database contents to disk. We worked hard on designing it in a way that makes sense for the browser. It uses the private origin file system [1] and stores the vectors in a compact format (one byte per vector dimension). Since storage space is at a premium in the browser, we also provide built-in PCA to allow you to compress your vectors. It’s completely transparent to the user and automatically kicks in once a vector storage file exceeds 10mb. We’re trying to think of a better way to design this API, so let us know any i

Transit Month is Taking Over the Bay Area By Guest Authors Rebecca Gibian and Reanne Lacosta, San Francisco Transit Riders Transit Month 2023 is a celebration of the role of public transportation in our communities and the Bay Area’s economic, social and cultural vibrancy. In the span of just eight years, it has grown from Transit Day into Transit Week and into the robust month it is now, thanks to our partnership with Seamless Bay Area and other transit-focused agencies and organizations. Together we have reached hundreds of riders through events held across the city.   We love seeing people get on transit and enjoy themselves, the ride and the experience. We appreciate that Transit Month encourages people to take a trip they never have or try a new line. We love seeing the shift that happens when people take the bus or train, realize how easy and affordable it is and then continue to do so (and tell their friends)!  Transit Month is a time to show our support for the people who
