[Archit Chatterjee @Archit_Techy]

@help_delhivery @RajeevSinghBenQ Please help me and Look into this matter.

[Archit Chatterjee @Archit_Techy]

@help_delhivery How much time you guys will take to answer me. I didn't get any help from you @delhivery. And shame on you @BenQIndia you guys stopped taking my Calls and even you didn't care to look into the matter.

I love Linux ❤️ I mean just notice the CLI commands.
curl, unzip, touch, strip, sleep 🫣

If you’re preparing for software engineering interviews, don’t just grind DSA.

Make sure you can explain these:

• How DNS works
• TCP vs UDP
• HTTP vs HTTPS
• REST vs gRPC
• Processes vs threads
• ACID
• Database indexing
• Caching
• Load balancing
• Message queues
• CAP theorem
• Idempotency
• Rate limiting
• Authentication vs authorization

These are the concepts that make you sound like an engineer, not just someone who solves LeetCode 🤡

Save this for future preparations 🫶

8 RAG Architectures Developers Should Know.

RAG isn't one fixed architecture. It's a spectrum of retrieval approaches that determine what gets searched, how results are ranked, and how much control the LLM has over retrieval.

Knowing these architectures is important. But understanding how to evaluate and choose the right one for your application is just as important.

Learn more about that here: https://t.co/eyIBu7mNEc

1. 𝗡𝗮𝗶𝘃𝗲 𝗥𝗔𝗚
↳ Retrieves the top matching chunks from a vector store and passes them directly to the LLM.

2. 𝗛𝘆𝗯𝗿𝗶𝗱 𝗥𝗔𝗚
↳ Combines keyword search with vector search, which helps when both exact terms and semantic meaning matter.

3. 𝗥𝗲𝗿𝗮𝗻𝗸𝗲𝗱 𝗥𝗔𝗚
↳ Retrieves a larger candidate set first, then scores and reorders chunks so the most relevant context gets used.

4. 𝗠𝘂𝗹𝘁𝗶-𝗤𝘂𝗲𝗿𝘆 𝗥𝗔𝗚
↳ Rewrites one question into multiple related queries to improve recall across different phrasings and document matches.

5. 𝗛𝗶𝗲𝗿𝗮𝗿𝗰𝗵𝗶𝗰𝗮𝗹 𝗥𝗔𝗚
↳ Searches broad document sections first, then narrows into smaller chunks for more precise retrieval.

6. 𝗚𝗿𝗮𝗽𝗵 𝗥𝗔𝗚
↳ Represents knowledge as entities and relationships, which helps when the answer depends on connected facts.

7. 𝗖𝗼𝗿𝗿𝗲𝗰𝘁𝗶𝘃𝗲 𝗥𝗔𝗚
↳ Checks whether retrieved context is useful and adjusts the retrieval process when the first results are weak.

8. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗥𝗔𝗚
↳ Lets the LLM plan retrieval steps, choose tools or sources, and reason through multiple searches before answering.

Here's a simple mental model: Naive = fast and simple. Hybrid + Reranked = better precision. Multi-Query + Hierarchical = broader coverage. Graph = connected facts. Corrective = self-checking. Agentic = autonomous reasoning.

RAG helps models retrieve knowledge. Memory systems help them retain it. If you want to learn how production AI evolves beyond RAG into stateful memory systems, here's a great deep dive → https://t.co/MMG8YivtUW
