On Unix and Linux systems, we can use the "tail -f" command to view and monitor the information in the log files generated by the system or software. This is a very useful feature for programmers or system administrators. It's a pity that Windows doesn't have this feature built in. If you need to implement similar functions, you can use a third-party program, Tail4win.

Windows Update represents an integral component of Microsoft's strategy to ensure that all users receive the necessary bug fixes, patches, and enhancements in a timely manner. However, Windows system updates are very criticized, especially the automatic updates of Windows 10, which occasionally prompts that there is insufficient space to download updates, but does not clearly tell you how much it needs.

Mechanical hard drives can be very fast when reading sequential files, such as copying movies. But when we usually use the operating system, the most common application is reading scattered files, such as operating system startup, opening programs, web browsing cache, etc. Each time we need to read many small files distributed in different locations on the disk. Mechanical hard drives rely on the magnetic head to constantly seek before it can read. It seeks and reads again and again, so a lot of time is spent on seeking and reading scattered small files.
