The security of the configuration of files in the Linux operating system depends on many factors that can be referenced to the system level and the applicable level. The most important thing about the security of Linux operating systems is its dynamism, for example, when you secure your Linux system, it will not stay safe forever, because applications and cyber criminals through new threats and/or new exploits that are packaged Systems or applications that cause the operating system to become unsafe, for this reason, we need a secure operating system. The main purpose of this article is to provide a new way to enhance the security of the Linux operating system. For this purpose, how can simple, continuous, and practical Linux environment be secured, solutions are presented, also based on performance analysis of the proposed method and evaluation parameters for existing systems against the proposed system, the superiority of this method is introduced.

Containerization is a leading technological advancement in cloud-native developments. Virtualization isolates the running processes at the bare metal level but containerization isolates the processes at the operating system level. Virtualization encapsulates all the new virtual instances with a new operating system but containerization encapsulates the software only with its dependencies. Containerization avoids the problem of dependency missing between different operating systems and their distributions. The concept of containerization is old but the development of open-source tools like Docker, Kubernetes, and Openshift accelerated the adaption of this technology. Docker builds container images and Openshift or Kubernetes is an Orchestrating tool. For stateful applications, Kubernetes workload resources are not a better option to orchestrate the application, as each resource has its own identity. In such cases, the operator can be built to manage the entire life cycle of resources in the Kubernetes cluster. Operator combines human operational knowledge into software code in a systematic way. The paper discusses the default control mechanism in Kubernetes and then it explains the procedure to build the operator to orchestrate the stateful application.

Tasks Scheduling

Wireless Sensor Networks (WSNs) are a growing research area as a large of number portable devices are being developed. This fact makes operating systems (OS) useful to homogenize the development of these devices, to reduce design times, and to provide tools for developing complex applications. This work presents an operating system scheduler for resource-constraint wireless devices, which adapts the tasks scheduling in changing environments. The proposed adaptive scheduler allows dynamically delaying the execution of low priority tasks while maintaining real-time capabilities on high priority ones. Therefore, the scheduler is useful in nodes with rechargeable batteries, as it reduces its energy consumption when battery level is low, by delaying the least critical tasks. The adaptive scheduler has been implemented and tested in real nodes, and the results show that the nodes lifetime could be increased up to 70% in some scenarios at the expense of increasing latency of low priority tasks.

The use of traditional approaches to teach Operating Systems usually lacks the visual aspect. The following research investigates the novel use of DEVS (Discrete Even Visualization and Simulation) in simulating the operation of an operating system. Cd boost++ was the framework of choice for this project. The simulation successfully mimicked the work of an operating system by simulating multiple cycles of program requests. This simulation is capable of further enhance the explanation of how an operating system works. The cases studied in this work include: 1- two processes running concurrently doing multiple IO’s, 2-four processes running concurrently based on a first come first serve scheduling algorithm, and 3- 20 processes running concurrently using highest priority scheduling algorithm. Output observation of the last case show promising results of successful use of DEVS and cd boost++ as a framework to build an operating system.

Technology is being used and improved by human beings over a long period of time now and Smartphones is one of them. Smart Phones contain touch screen, built in keyboard, high resolution camera, front side camera for video conferencing, etc. They are used for making and receiving calls, sending and receiving messages, accessing the Internet, digital media, incorporating audio/video recording etc. Different smart phones have different operating systems and mobile applications are developed for each operating system in smart phones, tablet or mobile phones, in order to serve the needs of the user. These apps are either preinstalled or downloadable from online app market that can do almost everything. Apps make a mobile be like a portable computer having multi core processors, gigabytes of memory and a real operating system. Originally mobile apps were made available for only calling, messaging and informational purposes like calendar, weather forecast, e- mail, etc. With improvement in technology and increase in user demands, developers started making apps for other purposes like games, banking, video chats etc. Some apps are also used to present data in the same format as on a computer website and also allow you to download content that you can use when there is no Internet. There are many apps available in market today for different Operating Systems in which Android is having the maximum market share these days.

Comparisons between biodiversity and other complex systems can facilitate cross-disciplinary exchange of theories and the identification of key system processes and constraints. For example, due to qualitative structural and functional analogies to biological systems, coupled with good data accessibility, computer operating systems offer opportunities for comparison with biodiversity. However, it remains largely untested if the two systems also share quantitative patterns. Here, we employ analogies between GNU/Linux operating systems (distros) and biological species, and look for a number of well-established ecological and evolutionary patterns in the Linux universe. We demonstrate that patterns of the Linux universe match the macroecological patterns: Linux distro commonness and rarity (popularity of a distro) follow a lognormal distribution, power law mean-variance scaling of temporal fluctuation, and there is a significant relationship between niche breadth (number of software packages) and commonness. The diversity in the Linux universe also follows general macroevolutionary patterns: The number of phylogenetic lineages increases linearly through time, with clear per-species diversification and extinction slowdowns, something that is unobservable in biology. Moreover, the composition of functional traits (software packages) exhibits significant phylogenetic signal. Our study provides foundations for using Linux as a model system for eco-evolutionary studies, as well as insights into patterns and dynamics of computer operating systems, which may be used to inform their future development and maintenance. The co-emergence of patterns across systems suggests that some patterns might be produced by system-level properties, independently of system identity, which offers an empirical argument for non-biological explanations of fundamental biodiversity patterns.
