A hidden file or folder is just a normal file or folder with a “hidden” option set. Operating systems hide these files by default, so you can use this trick to hide some files if you share a computer with someone else.
Linux, Mac, and other Unix-like systems display “load average” numbers. These numbers tell you how busy your system’s CPU, disk, and other resources are. They’re not self-explanatory at first, but it’s easy to become familiar with them.

When you run a command using sudo in Linux, the Terminal prompts you to type in your password with no visual feedback as you type. We’ll show a quick tweak that will show asterisks (*) when you type in your password in the Terminal.
Downloading files from the PHP mirrors is annoying, because by default the redirector makes the name of the filename change to just “mirror.” So how do you fix this? Luckily wget has a simple argument that you can use to fix it — and it is useful for many scenarios.
Nautilus contains some pre-defined bookmarks that provide quick and easy access to some common folders, such as Music and Pictures, as well as devices such as USB flash drives and network locations. You can add custom bookmarks to quickly access folders you use often.

Linux distributions tend to use two different types of release cycles: standard releases and rolling releases. Some people swear by rolling releases to have the latest software, while others like standard releases for being more stable and tested.
Passwords can be reset or bypassed on every operating system. On Windows, Linux, and Mac OS X, you can gain access to a computer’s unencrypted files after resetting the password — the password doesn’t actually prevent access to your files.
