  • What Good Is a Linux Client?
    Preparing Today for Linux® Tomorrow What Good is a Linux Client? A Linux White Paper Preface Anyone who has followed the progress of Linux the past few years has noted the surprising gains that Linux has made in server operating system market share and “mindshare” against the entrenched opposition, notably Microsoft® Windows NT®, Novell Netware and various varieties of UNIX®. A complete Linux network, of course, would require Linux clients (networked PCs or terminals) as well. Therefore, an important question is, “Is Linux a viable desktop operating system for general business use?” or must we continue to be confined to the Windows world for our non-server needs? And what about laptop support, or a Small Office/Home Office (SOHO) user or home user, who does not need a network server? Is there a place for Linux in a stand-alone environment? These are some of the questions this paper addresses. I must confess that until recently I was merely a bystander watching with curiosity from the sidelines—without any real involvement— the progress Linux has made. So writing this paper not only gave me the excuse to join in on the action, but it also provides you with the perspective of a Linux “newbie” who is attempting to find the applications and utilities needed to create a working system. The conventional wisdom so far is that Linux is not “ready for prime time” as anything but a network operating system. We shall test this notion to see if I can find commercial, shareware and/or freeware programs for Linux to replace the existing applications I currently use with Windows.

  • Dissertation Submitted to the Graduate Faculty of Auburn University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy
    Repatterning: Improving the Reliability of Android Applications with an Adaptation of Refactoring by Bradley Christian Dennis A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 2, 2014 Keywords:Refactoring, Code Smells, Patterns, Non-functional Requirements, Verification Copyright 2014 by Bradley Christian Dennis Committee: David Umphress, Chair, Associate Professor of Computer Science and Software Engineering James Cross, Professor of Computer Science and Software Engineering Dean Hendrix, Associate Professor of Computer Science and Software Engineering Jeffrey Overbey, Assistant Research Professor of Computer Science and Software Engineering Abstract Studies of Android applications show that NullPointerException, OutofMemoryError, and BadTokenException account for a majority of errors observed in the real world. The technical debt being born by Android developers from these systemic errors appears to be due to insufficient, or erroneous, guidance, practices, or tools. This dissertation proposes a re- engineering adaptation of refactoring, called repatterning, and pays down some of this debt. We investigated 323 Android applications for code smells, corrective patterns, or enhancement patterns related to the three exceptions. I then applied the discovered patterns to the locations suggested by the code smells in fifteen randomly selected applications. I measured the before and after reliability of the applications and observed a statistically significant improvement in reliability for two of the three exceptions. I found repatterning had a positive effect on the reliability of Android applications. This research demonstrates how refactoring can be generalized and used as a model to affect non-functional qualities other than the restructuring related attributes of maintainability and adaptability.

  • The Changing Face of the History of Computing: the Role of Emulation in Protecting Our Digital Heritage
    The Changing Face of the History of Computing: The Role of Emulation in Protecting Our Digital Heritage David Anderson, Janet Delve, and Vaughan Powell Future Proof Computing Group, School of Creative Technologies, University of Portsmouth, UK [email protected], {Janet.Delve,vaughan.powell}@port.ac.uk Abstract. It is becoming increasingly common for some source material to arrive on our desks after having been transferred to digital format, but little of the material on which we work was actually born digital. Anyone whose work is being done today is likely to leave behind very little that is not digital. Being digital changes everything. This article discusses the issues involved in the protection of digital objects. Keywords: digital preservation. Erasmus summarised well the outlook of many historians of computing when he remarked “When I get a little money, I buy books; and if any is left I buy food and clothes”! Most of us love second-hand bookshops, libraries and archives, their smell, their restful atmosphere, the ever-present promise of discovery, and the deep intoxication produced by having the accumulated knowledge of the world literally at our fingertips. Our research obliges us to spend many happy hours uncovering and studying old letters, notebooks, and other paper-based records. It is becoming increasingly common for some source material to arrive on our desks after having been transferred to digital format, but little of the material on which we work was actually born digital. Future historians of computing will have a very different experience. Doubtless they, like us, will continue to privilege primary sources over secondary, and perhaps written sources will still be preferred to other forms of historical record, but for the first time since the emergence of writing systems some 4,000 years ago, scholars will be increasingly unable to access directly historical material.

  • Mac Operating System 7.1 Introduction Mac OS Is a Series
    Page 1 of 6 Mac Operating System 7.1 Introduction Mac OS is a series of graphical user interface-based operating systems developed by Apple Inc. for their Macintosh line of computer systems. The original operating system was first introduced in 1984 as being integral to the original Macintosh, and referred to as the "System". Referred to by its major revision starting with "System 6 and "System 7", Apple rebranded version 7.6 as "Mac OS" as part of their Macintosh clone program in 1996. The Macintosh, specifically its system software, is credited with having popularized the early graphical user interface concept. Macintosh operating systems have been released in two major series. Up to major revision 9, from 1984 to 2000, it is historically known as Classic Mac OS. Major revision 10, from 2001 to present, is branded OS X (originally referred to as Mac OS X). Major revisions to the Macintosh OS are now issued as point revisions, such that, for example, 10.2 is substantially different from 10.5. Both series share a general interface design, and there has been some overlap with shared application frameworks and virtual machine technology for compatibility; but the two series also have deeply different architectures OS X, introduced as Mac OS X in 2001 and renamed OS X in 2012, is the latest version of Apple's operating system. Although it is officially designated as simply "version 10" of the Mac OS, it has a history largely independent of the earlier Mac OS releases. The operating system is the successor to Mac OS 9 and the "classic" Mac OS.
