Jim Fisher discusses a performance issue encountered while developing his note-taking app, Granola, on an M2 MacBook, where the app was using unexpectedly high CPU (60%) and GPU (25%) resources due to a CSS animation. He explains how to identify and improve expensive animations using Chrome's dev tools, particularly through the "Performance" and "Layers" tabs. From his investigation, he discovered that the app's action bar was repainting every frame due to a volume visualizer animation, causing

The text discusses the challenges faced by Hyperswitch in scaling distributed systems using Kubernetes and Kafka. Despite recognizing the importance of performance, cost, and operational efficiency, they encountered inefficiencies with resource allocation in Kubernetes, leading to increased costs due to under-provisioned resources. The auto-scaling feature struggled with their stateful Kafka workloads, causing delays and management difficulties. As a solution, they transitioned from Kubernetes to EC2, which resulted in improved performance, simplified operations, and a 28% reduction

Jacob Pratt reflects on his five years of maintaining the time crate, mentioning significant code changes and the absence of substantial optimization efforts. Although benchmarks existed, he had not developed a new date-time algorithm from scratch. Despite the crate's performance being acceptable, he feels it's time for a performance audit and optimization, partly motivated by a personal desire to improve the project. Among various tasks he has, he identifies the `Date::to_calendar_date` method as a candidate for optimization. He describes the method's implementation

The article discusses the need for delayed actions in programs, such as setting timeouts and sending keep-alives, particularly in C with a non-blocking event loop similar to NodeJS or Redis. The author found that there is no consistent libc function or syscall for creating timers across Unix systems, as each variant handles it differently. This contrasts with Windows, whose timer APIs, like SetTimer and WM_TIMER events, are simpler and more unified. The author notes that POSIX's approach to timers is inadequate

The Dębiec Water Treatment Plant in Poznań, Poland, utilizes mussels as bioindicators to monitor water quality in the Warta River, the city's main drinking water source. Mussels, which close their shells in response to pollution, are equipped with sensors that relay water quality information to a computer system. When the water is clean, the mussels remain open; if pollution occurs, their closure triggers an alert. This innovative system integrates the natural detection capabilities of mussels with modern
