Applying Flow Metrics to Design Resilient Microservices
Software design with resilience is an acknowledgement to the reality that everything fails. We put metrics in place to help us detect and resolve such problems and failures. Flow metrics, commonly used to measure how well teams deliver software, can be used to measure and improve system resilience.

A Framework for Building Micro Metrics for LLM System Evaluation
LLM accuracy is a challenging topic to address and is much more multi-dimensional than a simple accuracy score. Denys Linkov introduces a framework for creating micro metrics to evaluate LLM systems, focusing on goal-aligned metrics that improve performance and reliability. By adopting an iterative "crawl, walk, run" methodology, teams can incrementally develop observability.

Spring Security Configuration with Flow Diagrams
In modern Java systems, Spring Security is widely used, offering numerous settings for various scenarios. This diversity can be confusing when more specific configurations beyond the default formLogin(withDefaults()) are needed. This article demonstrates basic configurations with detailed component analysis through diagrams and code examples, providing a starting point for further customization.

Being Functionless: How to Develop a Serverless Mindset to Write Less Code!
Dynamic cloud services like AWS Lambda have revolutionized computing, leading to rapid deployment and innovation in serverless technology. However, over-reliance on Functions as a Service (FaaS) can create complex architectures and increase costs. Adopting a functionless mindset and leveraging native service integrations fosters simplicity, enhances sustainability, and optimizes efficiency.

Beat the Plan: Probabilistic Strategies for Successful Software Delivery at Scale
Large-scale software delivery demands managing complexity across teams and organizations. Similarly to betting strategies in Vegas, embracing probabilistic thinking helps tackle uncertainty, shifting from rigid plans to adaptive systems. By making informed bets and designing for change, leaders can control volatility, respond to evolving conditions, and drive success in dynamic environments.
