How does a database handle 200 different versions of Harry Potter without breaking? If you read the 1997 hardcover and someone else listens to the 2026 audiobook, how does the system know to log them as the same story rather than two completely different objects? And most importantly, how can an algorithm recommend a book based on a specific feeling without ever reading a single word of the text? To a human, it’s just a story. To a system, it is a potential data disaster.

The tools developers rely on are changing fast… but knowing which changes actually matter is the hard part. That’s why our CEO Fahim ul Haq just launched Future Stack, a new weekly newsletter focused on cutting through the noise and breaking down the shifts in software, infrastructure, and tooling that truly impact how we build and lead. From deep dives on emerging tech to thoughtful analysis of where the industry is headed, Future Stack is about sharpening your instincts, not chasing every headline. Written with developers in mind, but just as relevant for leaders and decision-makers who want to stay ahead of the curve. The first issue is live now so check it out and make sure to subscribe so you don’t miss future ones!

Autocomplete can feel like magic — until you're debugging code you barely understand. The key isn't avoiding AI tools, it's knowing how to use them effectively. Learn to code with AI assistance, not just copy-paste your way through. Our GitHub Copilot course teaches you how to integrate AI into your workflow without sacrificing understanding: https://lnkd.in/df8Z5s3u #GitHubCopilot #Educative #Coding #AI

Why do scalable systems rely on rate limiters? A rate limiter is more than just a traffic cop — it’s a critical defense mechanism in modern system design. From preventing abuse and DDoS attacks to ensuring fair usage and protecting system resources, rate limiters help keep high-traffic systems stable, secure, and cost-efficient. If you’re preparing for system design interviews or building real-world distributed systems, understanding where and how to implement rate limiting is essential. Learn how rate limiters work, where to place them, and how they fit into high-level architectures in our Grokking Modern System Design Interview course on Educative.

If your current RAG architecture feels like this meme — frantically trying to connect red strings between 10,000 disconnected documents — it’s time for an upgrade. Standard RAG acts like an unreliable witness. It dumps raw data on your desk without context and tells you, "Good luck, the answer is somewhere in that pile". This guide breaks down how to move from that chaotic conspiracy board to a structured Agentic Knowledge Graph. Here is what you’ll learn inside: — Why your current RAG system fails to connect the dots  — How to replace blind retrieval with a detective's case file architecture  — How to automate the validation of every fact before it hits your graph Swipe through to see how to solve the case.

Awards season is officially here! While Hollywood walks the red carpet, we’re handing the trophy for Best Supporting Architecture to Slack. Great engineering is the art of making the difficult look easy. Here are the 3 technical performances that deserve a standing ovation: 🥇 Best Retrieval: How to search 50 billion rows instantly without scanning them one by one. 🥇 Best Crowd Control: How to handle a "Thundering Herd" of 50,000 notifications without crashing the server. 🥇 Best Continuity: The "GPS" logic that clears your unread badges across all devices simultaneously. Swipe to see the winning designs. Want to master these concepts on the move?

"AI will not take your job, but the people who know it will." It’s the most repeated phrase in tech right now, yet it misses the actual problem: most people want to learn AI, they just don’t know where to start. Garima Bhandari, Software Engineer & AI Educator, argues that jumping straight into complex tools is a mistake. Before you build with AI, you need to learn to think with it. Garima breaks down a 5-step roadmap to move from "intimidated" to "proficient" in 2026: — Build the Foundation: Don't just memorize commands; learn Python to understand how computers think. — Start Creating: Move beyond theory by building a Generative AI project from the ground up. — Master Control: Learn Prompt Engineering not as magic words, but as structured instructions to reduce ambiguity. — Automate: advance to building intelligent AI Agents that can act and collaborate. — Connect: Use MCP (Model Context Protocol) to let your agents talk to other tools and apps. Tools will change and models will evolve. But the ability to filter noise and make decisions? That is the real leverage that lasts forever.

Picture this: It's January 1st. 20 million people just opened Notion. Most systems would crash. How does Notion let you plan out your resolutions without breaking the database? 🔀 Sharding – Split users across servers by workspace ID so one traffic jam doesn't freeze everyone 💾 Three-tier storage – Postgres for structure, Memcached for speed, S3 for heavy files ✈️ Offline-first sync – Write on a plane, reconcile when you land 🔍 Background indexing – Async workers update search without blocking your typing Wanna master the architecture?
