Volatile and non-volatile memory serve distinct purposes in modern computing. Understanding how they work together is essential to how devices store and process data.
Volatile memory requires constant power to retain data. RAM (random access memory) is the primary example—it stores active programs and data your device is currently using. Once power cuts off, volatile memory wipes clean.
Non-volatile memory persists without power. SSDs, hard drives, and flash storage retain files permanently until deliberately deleted. Your device boots from non-volatile storage and loads data into volatile RAM for processing.
The partnership is straightforward: non-volatile memory is your filing cabinet; volatile memory is your desk. You pull files from the cabinet and work with them on the desk. More volatile RAM speeds up multitasking. More non-volatile storage capacity holds more files.
Modern devices optimize this balance differently. Phones rely heavily on fast SSDs. Laptops balance both. Servers maximize RAM for intensive processing. This dynamic duo remains fundamental to how computers and devices operate.
Vibe coding has earned a negative reputation as lazy, AI-driven development, but its origins tell a different story. The practice predates recent AI hype.
Asahi Linux has announced official support for Apple's M3 chip family, expanding compatibility beyond M1 and M2 systems. The rollout comes with known limitations that users should understand before installing.
As artificial intelligence increasingly handles system incidents, engineers risk losing practical knowledge of their infrastructure. The trend raises concerns about skill degradation and decision-making capabilities when AI systems fail.
The Rust React Compiler has been integrated natively into Vite, the popular build tool. This integration enables faster compilation and improved performance for React applications.
