The Secret Masters of Time: Who Really Controls Your datetime.now()?
Who controls time in Python, JavaScript, Java, C#, and Go? Not the language creators. Not tech giants. A small team of volunteers whose decisions instantly propagate to billions of devices worldwide. Discover the shocking truth about the IANA Time Zone Database - the single source of temporal truth that every programming language secretly depends on.
In 5 breathtaking minutes, meet the Time Lords whose midnight email updates can break your production code, and trace the invisible pipeline from government timezone announcements to your datetime.now() calls.
The Hidden Complexity of Time in Serverless: A 5-Minute Reality Check
Picture this: A government announces a last-minute timezone change with just days of notice. Suddenly, your serverless application has the wrong time assumptions baked into immutable functions. Users get notifications at wrong times, business logic breaks, and support is flooded with "time bug" reports.
This happens 3-6 times per year as governments adjust timezone rules for political, religious, or economic reasons. In traditional servers, you'd update the timezone database and restart. In serverless? Your timezone data is frozen into deployment artifacts.
This lightning talk shows the one hybrid architecture pattern that actually works in production - preventing millions in downtime when governments decide to mess with time.
Every Wasted Dollar is Wasted Energy: GreenOps for AWS
Data centers now generate a larger carbon footprint than the airline industry, with cloud electricity demand projected to double by 2030. GreenOps—minimizing cloud carbon footprints through efficient resource utilization—addresses both environmental impact and cost optimization.
This session demonstrates how to implement GreenOps using AWS's Customer Carbon Footprint Tool and Well-Architected Sustainability Pillar. Learn GreenOps strategies. Through case studies attendees will gain a practical roadmap to measure and reduce cloud emissions while optimizing AWS costs.
