How to Think Like a Cloud Engineer: S3 Bucket 403 Forbidden – Access Denied Error Message: 403 Forbidden: Access Denied occurs when a user attempts to access an Amazon S3 bucket but lacks the necessary permissions. Preface: How DeepSeek’s Chain of Thought Approaches Cloud Problem-Solving Troubleshooting cloud errors isn’t just about finding the right fix—it’s about learning how to think through the issue like a seasoned engineer. DeepSeek’s Chain of Thought (CoT) method offers an interesting approach: it doesn’t leap to a single solution but instead walks through multiple layers of potential causes. This mirrors the thought process of experienced cloud engineers, who know that permissions, policies, and configurations must all align for access to work correctly. What makes DeepSeek unique is its ability to map out a structured, logical flow of debugging, ensuring that even complex AWS issues are broken down into manageable steps. DeepSeek's Chain of Thought (CoT): Thought for 61 se...

AI on Raspberry Pi: Testing Qwen 2.5 0.5B Clarifying the Issue Running AI models locally on the Raspberry Pi 5 is a challenge due to its hardware limitations, but with an 8GB RAM upgrade and improved processing power, it has potential as an edge computing device. This time, we tested Qwen 2.5 0.5B, a small-scale language model, using Ollama as our AI runtime. Our goal was to evaluate Qwen’s performance, reasoning ability, and overall usability on the Pi 5. This test was conducted on a Raspberry Pi 5 (8GB RAM) running Raspberry Pi OS Desktop (Bookworm). Why It Matters Cloud-based AI is dominant, but running local AI inference offers privacy, reduced latency, and offline capabilities. If Qwen 2.5 0.5B can function well on the Pi 5, it could enable lightweight AI-powered automation, assistants, and knowledge retrieval without requiring a server connection. The key question is whether Qwen 2.5 0.5B performs significantly better than TinyLlama in terms of accuracy, efficiency, and usability...
