Show HN: Cognita – open-source RAG framework for modular applications Hey HN, exciting news! Our RAG framework, Cognita ( https://ift.tt/Z4FJKkC ), born from collaborations with diverse enterprises, is now open-source. Currently, it offers seamless integrations with Qdrant and SingleStore. In recent weeks, numerous engineers have explored Cognita, providing invaluable insights and feedback. We deeply appreciate your input and encourage ongoing dialogue (share your thoughts in the comments – let's keep this ‘open source’). While RAG is undoubtedly powerful, the process of building a functional application with it can feel overwhelming. From selecting the right AI models to organizing data effectively, there's a lot to navigate. While tools like LangChain and LlamaIndex simplify prototyping, an accessible, ready-to-use open-source RAG template with modular support is still missing. That's where Cognita comes in. Key benefits of Cognita: 1. Central repository for parsers, loaders, embedders, and retrievers. 2. User-friendly UI empowers non-technical users to upload documents and engage in Q&A. 3. Fully API-driven for seamless integration with other systems. We invite you to explore Cognita and share your feedback as we refine and expand its capabilities. Interested in contributing?

Show HN: I made a spaced repetition tool to master coding problems https://ift.tt/R6BywWV

Show HN: I made a spaced repetition tool to master coding problems As you solve LeetCode questions, you can mark them as hard, medium, or easy. The tool will then recommend questions you should review based on (1) how hard the question was for you and (2) how much time has passed since you last reviewed it. I'd recommend normally attempting LeetCode problems and just marking them as hard, medium, or easy for you at first so the tool knows which problems to recommend you review! Here's the theory behind spaced repetition and learning if interested: https://ift.tt/r6K57yP https://www.lanki.xyz/ April 27, 2024 at 01:08AM

Show HN: I made a site for practicing front end debugging with real-world bugs https://ift.tt/0UNlqCd

Show HN: I made a site for practicing front end debugging with real-world bugs I am excited to introduce my solo project, a platform built with the frontend development community in mind. It's an interactive environment aimed at refining debugging skills through exposure to real-world bugs. This project stems from the need for a hands-on, practical method of learning to debug. The site features a variety of intentional bugs for users to solve, mirroring the types of challenges faced in professional settings. Over the coming weeks, I will be adding many more exercises and new features to enhance your learning experience further.

Show HN: I put PubMed in a vector DB https://ift.tt/RiDYvSM

Show HN: I put PubMed in a vector DB Hi HN, As a researcher, I often found myself struggling with the limitations of keyword-based search when exploring PubMed papers. To address this, I created PubMed Search ( https://ift.tt/TS6INsi ), a tool that leverages a vector database to enable semantic search across medical research literature. Some key features: * Daily updates to ensure access to the latest articles * Semantic search using latest & greatest embedding models * Some additional useful info about the papers (tldr, journal, publication date, etc.) Hope you find it useful! https://ift.tt/TS6INsi April 26, 2024 at 01:23AM

Show HN: ReaperAI – Automatically delete dead code from your app https://ift.tt/mfghMlQ

Show HN: ReaperAI – Automatically delete dead code from your app Hi all, We launched Reaper at the end of last year ( https://ift.tt/sBMjCwb... ) with the goal of helping teams discover dead code in their mobile apps. Unlike typical static analysis that only finds technically unreachable code, Reaper is an SDK that monitors production data to discover code that's unused by real users (ex. stale feature flags). ReaperAI takes this a step further by actually being able to open pull requests in your repo to automatically delete the dead code that it finds. Here is a demo video: https://www.youtube.com/watch?v=y2FEaAmUvNw We're here to answer your questions & would love to hear any ideas or feedback you have! https://ift.tt/IzMK248 April 25, 2024 at 09:55PM

Show HN: I've developed an open-source proxy server for front end applications Hey Everyone! I’ve recently been working on an open-source proxy server to help front end applications securely access third party APIs that require confidential API keys without the need to create your own backend. I would love to get some feedback and hear what you think! https://ift.tt/zY6fZbn April 25, 2024 at 05:32AM
