Linux is based on the earlier Unix system, which used the principle of modular design. In this type of system, the OS provides simple tools, while shell scripting and command language combine to perform complex workflows. Linux supports a number of languages, including PHP, Perl, Ruby, Python...
Ext4: ext4, standing for “fourth extended system”, was created in 2006. Because this file system overcomes numerous limitations that the third extended system had, it is both widely used, and the default file system that most Linux distros use. While it may not be the most cutting edge, ...
Today Linux is one of the most widely used Operating Systems and it come in various variants like Ubuntu, CentOS, Fedora, Debian, openSUSE, RedHat, MX Linux, Arch Linux, Gentoo etc. Several people can use a Unix computer at the same time; hence Unix is called a multiuser system. A user...

Linux is an open source operating system made up of the kernel, the base component of the OS, and the tools, applications, and services bundled with it.
These applications interact with the kernel via an explicitly-definedapplication programming interface(API) orsystem call interface(SCI). No access to the kernel is available outside of this API/SCI, which is an important security concept. Two examples of system calls that an application may make...
Kubernetes is based on the principles of control theory. It allows users to manage their applications lifecycle by creating, modifying or deleting resources that are tracked by controllers, thus regulating the state of the entire system. In the Kubernetes API, every resource corresponds to a specifi...

We cannot completely avoid system calls entering uninterruptible sleep. As we discussed, they are something present in Linux, and programming with them is helpful. From a user point of view, there is not much that we can do. Most of the system calls that are uninterruptible happen instantaneous...
