Operating System Development
The development of a hobbyist operating system is one of the more involved and technical options for a computer hobbyist. The definition of a hobby operating system can sometimes be vague. It can be from the developer's view, where the developers do it just for fun or learning; it can also be seen from the user's view, where the users are only using it as a toy; or it can be defined as an operating system which doesn't have a very big user base. Development can begin from existing resources like a kernel, an operating system, or a bootloader, or it can also be made completely from scratch. The development platform could be a bare hardware machine, which is the nature of an operating system, but it could also be developed and tested on a virtual machine. Since the hobbyist must claim more ownership for adapting a complex system to the ever-changing needs of the technical terrain, much enthusiasm is common amongst the many different groups attracted to operating system development. ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer (usual ...

Redox (operating System)
Redox is a Unix-like microkernel operating system written in the programming language Rust, which has a focus on safety, stability, and performance. Redox aims to be secure, usable, and free. Redox is inspired by prior kernels and operating systems, such as SeL4, MINIX, Plan 9, and BSD. It is similar to GNU and BSD, but is written in a memory-safe language. It is free and open-source software distributed under an MIT License. Redox gets its name from the reduction-oxidation reactions in chemistry; one redox reaction is the corrosion of iron, also called rust. Design The Redox operating system is designed to be secure. This is reflected in two design decisions: # Using the programming language Rust for implementation # Using a microkernel design, similar to MINIX Components Redox provides packages ( memory allocator, file system, display manager, core utilities, etc.) that together make up a functional operating system. Redox relies on an ecosystem of software written in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phantom OS
Phantom OS is an operating system (OS) made by mostly Russian programmers (with help of some Uzbeks). It is based on a concept of persistent virtual memory, and uses a virtual machine, managed code, and bytecodes. It is one of a few OSes not based on classic concepts of Unix-like systems. Its primary goal is to achieve simplicity and effectiveness in both the operating system and application software at the same time. It is free and open-source software (FOSS) released under a GNU Lesser General Public License (LGPL). Phantom is based on the principle that "Everything is an object", in contrast to the Unix-like approach of "Everything is a file". Basics ''Managed code'' – Memory protection on object level, rather than process level; absence of pointer arithmetic in managed code avoids many problems that exist and occur in unmanaged code. ''Global address space'' – Very effective and inexpensive inter-process communication (IPC). Single (flat) address space allows transfer ...

HelenOS
HelenOS is an operating system based on a multiserver microkernel design. The source code of HelenOS is written in C and published under the BSD-3-Clause license. The system is described as a “research development open-source operating system”. Technical overview The microkernel handles multitasking, memory management and inter-process communication. It also provides kernel-based threads and supports symmetric multiprocessing. Typical to microkernel design, file systems, networking, device drivers and graphical user interface are isolated from each other into a collection of user space components that communicate via a message bus. Each process (called ''task'') can contain several threads (preemptively scheduled by the kernel) which, in turn, can contain several fibers scheduled cooperatively in user space. Device and file-system drivers, as well as other system services, are implemented by a collection of user-space tasks (''servers''), creating thus the multise ...

Ghost (operating System)
Ghost is an open-source hobbyist operating system and kernel. It has been under development since 2014 and is currently compatible with the x86 platform. The system is based on a microkernel and features symmetric multi-processing and multitasking. Most of the kernel and system program are written in C++. Design The architectural concept is a micro-kernel design. Many of the functionalities that are usually integrated in the kernel in a monolithic or hybrid system are implemented as user-level applications. All system drivers are running as user-space processes. This approach attempts to improve stability and to avoid crashes due to faulty access or memory corruption. The system supports 32-bit ELF binary and shared object loading. The kernel provides a system call API that is used for all inter-process communications and system commands. Driver processes access this interface to manage memory or request direct resource access. The window manager provides a messaging interf ...

GeckOS
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick ...
