Caching: Abstraction, Not Optimization

The conventional wisdom is that caching speeds up software. The author argues this is only part of the story. After working with data movement between object storage, disk, and memory, the author posits that caching's more crucial role is simplifying software. The article explores the limitations of pre-baked caching algorithms (LRU, LFU, etc.) and suggests caching acts more as an abstraction layer, hiding the underlying storage details, freeing programmers from worrying about data tier location. Database and OS caching mechanisms exemplify this abstraction. While caching can have issues, like OS page cache and fsync misuse, this doesn't necessitate abandoning caching but rather understanding and using it better.

Quantum Systems and the Arrow of Time: A Groundbreaking Discovery

2025-02-16

A study published in Scientific Reports explored the interaction of a quantum system with its environment (an open quantum system), attempting to explain why we perceive time as flowing in one direction. By simplifying the model and assuming a vast environment where energy and information don't return, researchers investigated how time emerges as a unidirectional phenomenon. Surprisingly, even under these assumptions, the system behaved identically whether time moved forward or backward. This provides a mathematical foundation for time-reversal symmetry still holding in open quantum systems, suggesting the arrow of time may not be as fixed as we experience.
