Chapter 1. Origins of Mac OS X
1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years. -
The Arcos Network Operating System
AT-A-GLANCE The ArcOS TM Network Operating System History has repeatedly proven that large industries transition from The ArcOS Advantage vertical integration to best-in-class horizontal segmentation as the urgent business need for innovation outstrips the ability/intent of the incumbents to deliver. The networking industry is in exactly such Agile situation, but it lags the compute and, to a large extent, the storage tiers in terms of this transition. Network operations teams are hampered by inflexible, proprietary systems that are expensive to build, operate, Automated processes accelerate and manage. This model does not fit well into today’s digital business and streamline network expectations of a more agile and innovation-friendly smart infrastructure. provisioning, operations, and deployment.

1. Introduction
Network Operating Systems Partha Dasgupta Department of Computer Science and Engineering Arizona State University Tempe AZ 85287-5406 USA [email protected] [Note: Written in 1997, Appeared in Encyclopedia of Electrical Engineering] 1. Introduction Network Operating Systems extend the facilities and services provided by computer operating systems to support a set of computers, connected by a network. The environment managed by a network operating system consists of an interconnected group of machines that are loosely connected. By loosely connected, we mean that such computers possess no hardware connections at the CPU – memory bus level, but are connected by external interfaces that run under the control of software. Each computer in this group run an autonomous operating system, yet cooperate with each other to allow a variety of facilities including file sharing, data sharing, peripheral sharing, remote execution and cooperative computation. Network operating systems are autonomous operating systems that support such cooperation. The group of machines comprising the management domain of the network operating system is called a distributed system. A close cousin of the network operating system is the distributed operating system. A distributed operating system is an extension of the network operating system that supports even higher levels of cooperation and integration of the machines on the network (features include task migration, dynamic resource location, and so on) (1,2). An operating system is low-level software controlling the inner workings of a machine. Typical functions performed by an operating system include managing the CPU among many concurrently executing tasks, managing memory allocation to the tasks, handling of input and output and controlling all the peripherals. -

Deploying IP Storage Infrastructures
White Paper Deploying IP Storage Infrastructures The cost of deploying and maintaining traditional storage networks is growing at an exponential rate. New requirements for compliance and new applications such as analytics mean that ever-increasing volumes of unstructured data are collected and archived. Legacy storage networks cannot meet the need to scale-out capacity while reducing capital and operational expenditures. In response to this challenge, new storage architectures based on IP/Ethernet have evolved, and are being adopted at an ever-increasing rate. While technologies such as NAS and iSCSI are widely deployed, Fibre Channel SANs have maintained a dwindling but still strong presence in enterprise architectures. This paradigm is beginning to change as scale-out storage systems enabled by Software Defined Storage (SDS) are increasingly mature. The ability to reclaim stranded Direct Attached Storage (DAS) assets in a server infrastructure combined with the efficiencies gained by running storage traffic over the same IP/Ethernet network as standard data traffic provides an undeniably strong opportunity to reduce both the capex and opex required to deploy and run a storage infrastructure. According to some estimates, as much as a 60% capex reduction is achievable by deploying an SDS architecture which leverages server DAS to create a VSAN. Even without such radical savings, scale-out storage relying on IP/Ethernet offers dramatic savings over traditional Fibre Channel based storage. Most future IT asset deployments will leverage 10 Gigabit Ethernet (10GbE) and now 40 Gigabit Ethernet [40GbE]) for the underlying storage interconnect for newer applications. Traditional datacenter networks however are not designed to support the traffic patterns and loss characteristics to reliably deploy an IP/Ethernet storage infrastructure. -

The Era of Microsoft? Technological Innovation, Network Externalities, and the Seattle Factor in the US Software Industry
The Era of Microsoft? Technological Innovation, Network Externalities, and the Seattle Factor in the US Software Industry Edmund A. Egan Working Paper 87 January 1996 Edmund A. Egan is a Doctoral Candidate in the Department of City and Regional Planning at the University of California at Berkeley. - 1 - Abstract Microsoft Corporation, the largest company in the US software industry, has been under anti-trust scrutiny from the Department of Justice for most of the 1990s. In 1995, its planned acquisition of Intuit, Inc. prompted a Silicon Valley law firm, on behalf of unnamed complainants, to submit a White Paper to the DOJ, on the subject of Microsoft's long-term strategy. The White Paper, relying on the theoretical concepts of network externalities and lock- in effects, argues that Microsoft will use Intuit's products to attain monopolistic positions in network operating systems, on-line services, and electronic commerce, and will eventually be in a position to affect the content transmitted over electronic networks. This paper disputes that claim. First, an analysis of Microsoft's growth vs. the US packaged software industry a whole is presented, indicating that Microsoft actually has a fairly small share of total employment and sales. Secondly, a detailed review of the White Paper's argument is followed by a discussion of Microsoft's competitors, whose products also benefit from network externalities and lock-in effects. Ultimately, innovation will be more important than leverage for Microsoft. However, the paper argues that Microsoft's location in Seattle may prove to be a liability when it comes to rapid innovation; the corporation has grown much more rapidly than the Seattle software industry as a whole.
