Learn why agentic chunking beats every traditional RAG method — and why corn proves it.Tue, 06 Jan 2026 08:53:34 GMThttps://astro-paper.pages.dev/posts/ibm-docling-the-document-ai-pipeline/https://astro-paper.pages.dev/posts/ibm-docling-the-document-ai-pipeline/Still using basic PDF parsers? Docling brings AI-powered document understanding, layout detection, and smart chunking — built for modern LLM workflows.Wed, 31 Dec 2025 19:55:34 GMThttps://astro-paper.pages.dev/posts/deep-dive-into-semantic-chunking-for-rag/https://astro-paper.pages.dev/posts/deep-dive-into-semantic-chunking-for-rag/Most RAG pipelines fail not because of the model, but because of bad chunking. In this deep dive, we explore semantic chunking and how splitting text by meaning instead of size can dramatically improve retrieval accuracy.Fri, 26 Dec 2025 14:16:34 GMThttps://astro-paper.pages.dev/posts/different-chunking-methods-for-rag/https://astro-paper.pages.dev/posts/different-chunking-methods-for-rag/Boost your RAG performance by mastering chunking. Whether you use fixed-size, sentence-based, or semantic chunks, the right strategy improves retrieval accuracy and response quality. Smart chunking is the key to more relevant, efficient AI systems.Sat, 20 Dec 2025 13:46:34 GMThttps://astro-paper.pages.dev/posts/drive-integration/https://astro-paper.pages.dev/posts/drive-integration/Complete guide to connecting FastAPI and Google Drive using OAuth2Sat, 31 May 2025 15:20:35 GMThttps://astro-paper.pages.dev/posts/how-to-build-a-secure-text-based-license-verification-system-in-python/https://astro-paper.pages.dev/posts/how-to-build-a-secure-text-based-license-verification-system-in-python/Skip the flimsy date checks—this system uses sleek Ed25519 signatures so you can issue tamper-proof, copy-pasteable licenses that your app can instantly verify.Fri, 19 Apr 2024 16:46:34 GMThttps://astro-paper.pages.dev/posts/building-a-asymmetric-license-verification-system-with-python-and-rsa/https://astro-paper.pages.dev/posts/building-a-asymmetric-license-verification-system-with-python-and-rsa/In the world of software distribution, ensuring that a user’s license is valid—and hasn't been tampered with—is a critical challenge. While there are many modern cryptographic curves (like Ed25519), **RSA** remains the classic, battle-tested standard for digital signatures.Sun, 31 Dec 2023 16:46:34 GMT
