“…The first route is to ask the student to modify/enhance certain parts of a given OS kernel code base, implemented on some real/simulated hardware machine. Minix [1], XINU [2], PintOS [3], Topsy [4], TempOS [5], GeekOS [6], Nachos [7], OS/161 [8], OSP [9] and Xv6 [10] provide such environments. The student is asked to re-implement/modify certain central components of the kernel, such as scheduler, memory manager, or add a new file system, as decided by the course instructor.…”

An operating system project suitable for undergraduate computing/electrical sciences students is presented. The project can be used as a course project in a one semester course, or as a self-study project for motivated students. The course is organized such that a student with a basic background in programming and computer organization can follow the implementation road map available online, and build the OS from scratch on her personal machine/laptop, with minimal instructional supervision. The student is provided with a simulated abstract machine, an application interface specification, specification and design of the OS, and a step by step project implementation road map. The functionalities of the OS include multitasking, virtual memory, semaphores, shared memory, an elementary file system, interrupt driven disk and console I/O, and a limited multi-user support. The final stage of the project involves porting the OS to a two-core machine. An independent one semester compiler design project, where the student builds a compiler for a tiny object oriented programming language that generates target code that can be loaded and executed by the OS is also briefly discussed.

“…Out of convenience, a virtual machine (e.g., bochs) is typically used as development platform; though it is possible, with some assistance, to have students execute their OS in actual hardware. Examples of instructional operating systems following this philosophy are the uMPS/Kaya platform [Goldweber et al 2005], the TempOS platform [Pinto et al 2013], GeekOS [Hovemeyer et al 2004], VIREOS [Corliss and Melara 2011], Black's OS [Black 2009], and Chadwick's OS [Chadwick 2012]. The building of a toy OS approach has the following advantages: -There is no pre-existing OS to assimilate; -Building the system from the ground up demonstrates how the system fits together, thereby providing a holistic view of it;…”

MiniOS: an instructional platform for teaching operating systems labs

Delivering hands-on practice laboratories for introductory courses on operating systems is a difficult task. One of the main sources of the difficulty is the sheer size and complexity of the operating systems software. Consequently, some of the solutions adopted in the literature to teach operating systems laboratory consider smaller and simpler systems, generally referred to as instructional operating systems. This work continues in the same direction and is threefold.First, it considers the hardware platform that is simpler and popular. Second, it argues that a minimal operating system is a viable option for delivering laboratories.Third, it presents a laboratory teaching platform, whereby students build a minimal operating system for embedded systems. The proposed platform is called MiniOS.An important aspect of MiniOS is that it is sufficiently supported with additional technical and pedagogic material. Finally, the effectiveness of the proposed approach to teach operating systems laboratories is illustrated through the experience of using it to deliver laboratory projects in the Operating Systems course at the University of Northern British Columbia.ii Finally, from so little sleeping and so much reading, his brain dried up and he went completely out of his mind.
