  The Secret Life of AWS: Regions and Availability Zones Where your code actually lives — and why it matters #AWS   #CloudComputing   #Regions   #AvailabilityZones Margaret is a senior software engineer. Timothy is her junior colleague. They meet in a grand Victorian library in London — and in every episode, they work through the tools, ideas, and infrastructure that power modern software. Today, Timothy discovers that the cloud has an address. Episode 6 Timothy arrived early, notebook already open on the table, pen uncapped and waiting. He had the focused stillness of someone who had been thinking about a question for several days and had finally decided to ask it. "I built something last week," he said. "Small — a simple API, nothing production, just practice. And I noticed something." He looked at her. "The region selector. Top right corner of the Console. I had selected US East — Northern Virginia — because it was the default. Because it was there." He...

  The Secret Life of AI: The Rage Quit How to prompt, think, and get results from any AI tool #WorkingWithAI   #Prompting   #AIConfidence Margaret is a senior software engineer. Timothy is her junior colleague. They work in a grand Victorian library in London — and in every episode, they'll show you exactly how to get what you want from AI. Episode 5 Timothy arrived on a Wednesday, which was unusual. Their conversations had settled into a Thursday rhythm without either of them planning it. Margaret noted the day but said nothing as he sat down, unwound his scarf with slightly more force than necessary, and looked at the table rather than at her. "I closed the laptop," he said. Margaret waited. "Three days ago. I haven't opened it since. Not for AI work, anyway." He looked up. "I know what you're going to say." "You don't," she said pleasantly. "Tell me what happened." The Brilliant-Then-Terrible Sequence "I was work...

  The Secret Life of AWS: The Invisible Thread (AWS X-Ray) How to track requests across a decoupled event-driven architecture using distributed tracing #AWS   #XRay   #Observability   #DevOps Margaret is a senior software engineer. Timothy is her junior colleague. They work in a grand Victorian library in London — the kind of place where code quality is the unspoken objective, and craftsmanship is the only thing that matters. Episode 66 Timothy had six different browser windows open, each displaying a different stream of raw text. He was scrolling through his CloudWatch logs with a look of sheer exhaustion. He turned his monitor toward Margaret as she walked into the studio. "A VIP customer reported that their checkout took almost five seconds yesterday," Timothy explained, rubbing his eyes. "The API Gateway WebSockets worked perfectly, and the order eventually succeeded, but the latency was terrible. I have been looking through the logs for an hour and I have no ide...

  The Secret Life of Python: How to Use All Your CPU Cores A practical guide to multiprocessing for CPU-bound tasks #Python   #Coding   #Multiprocessing   #Threads Margaret is a senior software engineer. Timothy is her junior colleague. They work in a grand Victorian library in London — the kind of place where code quality is the unspoken objective, and craftsmanship is the only thing that matters. Episode 36 Timothy was ready to break the "Glass Ceiling." He knew now that his "Grandmaster Analysis" engine was too heavy for threads. It needed raw power, not just a guest waiting for a turn to speak. "To use all your cores," Margaret said, pointing to his laptop, "we have to stop trying to share one copy of Python. We’re going to give every worker their own room, their own memory, and—most importantly—their own Global Interpreter Lock." Timothy opened the  multiprocessing  module. It looked surprisingly similar to the  threading  module, but Margar...
