Linux

Today I learned about Volumio, a specialized Linux distribution designed for high-quality music playback on Raspberry Pi and other devices, perfect for audiophiles and music enthusiasts.

Today I learned about Slurm, a highly scalable workload manager for Linux clusters used in high-performance computing environments for job scheduling and resource management.

Today I learned about the fuser command, a powerful Linux utility for identifying which processes are using specific files, directories, or network ports.
