Turn your laptop into a powerful RAG system! LEANN can index and search through millions of documents while using 97% less storage than traditional solutions without accuracy loss. LEANN achieves this through graph-based selective recomputation with high-degree preserving pruning, computing embeddings on-demand instead of storing them all. Key Features: 🔒 Privacy: Everything stays on your laptop with no cloud and no hidden terms. 🪶 Lightweight: Smart graph pruning and CSR format cut down both storage and memory usage. 📦 Portable: Move your knowledge base across devices or share it with others at minimal cost. 📈 Scalable: Handles messy personal data and agent-generated memory that often crash traditional vector DBs. ✨ Accurate: Provides the same search quality as heavyweight solutions while using 97% less storage. It's 100% Open Source Link to the Github Repo in the comments!

AI agents combine LLMs with tools, memory, and workflows so they can fetch data, call APIs, and take actions. And in this tutorial, Manoj teaches you how to build your own AI agent using LangGraph. You'll learn about the tools, agent state, and the agent graph - and how to wire it all together. freecodecamp.org/news/how-to-de…

When you're building APIs in Node.js, there are some security best practices you should follow. These will help you harden your APIs and protect them from common threats. In this guide, Manish shows you how to use environment variables, validate input, rate limit your endpoints, and more. freecodecamp.org/news/how-to-ha…

Manual SQL scripts can turn your deployments into guessing games. In this guide, @ashutoshkrris shows you how to version-control database changes with Liquibase and Spring Boot. You'll create changeLogs and changeSets, track migration history, handle rollbacks, avoid schema drift, and ship database updates safely. freecodecamp.org/news/database-…

Medical imaging data needs more than standard ML preprocessing. In this guide, Lakshmi shows you how to prepare chest X-rays for machine learning with Python and OpenCV. You'll validate datasets, catch leakage, scale and normalize images, apply CLAHE, handle missing data, and more. freecodecamp.org/news/how-to-pr…

Data fetching in React can get tricky as your apps scale. And in this handbook, @tapasadhikary walks you through modern data fetching strategies. You'll first review useEffect, then learn how to use Suspense, the new use() API, and ErrorBoundary. freecodecamp.org/news/the-moder…

@cneuralnetwork Depends! Working 80hr a week for someone else's dream doesn't seem to be worth it. But the pay is lucrative. If one priorities family responsibility over self, Option B is good. If the priority is personal freedom and travelling, option A is the best.

@Cricketracker Overall Csk has the best points table standings. The 265 points of 17 seasons only. If we fill the remaining two seasons points using CSK's average (265/17 = ~15 points per season), the total would be 295 points. This list is unfair for CSK. Same goes for RR.

Basic web scrapers often break as soon as they hit CAPTCHAs, IP bans, or 403 errors. In this course, Gavin teaches you how to build production-ready web scrapers that work on modern websites. You'll use Playwright, Cheerio, residential proxies, and a MERN dashboard to scrape and visualize live data. freecodecamp.org/news/build-pro…

Sometimes deep learning models fail because of the data, not the architecture. In this article, Lakshmi walks you through how she diagnosed a medical imaging model that struggled to learn. You'll learn how to check dataset composition, subject leakage, label quality, synthetic-to-real gaps, plus when to stop tuning. freecodecamp.org/news/why-your-…
