...In this introduction, I provide any overview of the concepts regarding shell scripts. Explaining what is a shell script is and describing several common shells. Later, a tutorial is made available for demonstration how to backup a file or folder using a tool to accomplish these tasks. The SNTbackup is a shell script backup tool that gives users the option to select to select a file or folder to be backed up. A detail demonstration with screenshots is provided as a visual aid to readers. I used a simple Linux shell script to back-up the home directory of my system. The script uses the tar command to execute this task. SNTback is a simple, effective, fully customizable backup script that protects your folder by creating a duplicate of the specific folder. The duplicate of the selected folder is the place in a location of the user’s preference. Users will find the SNTbackup as a resource which allows folders such as directories to be back-up in no time....

...FOSS has it helped or has it hurt? Bonita Jones-Bey Class IT 302 Professor Emerenini July 26, 2013 Upon my undertaking of this assignment I wasn’t aware of the in-depth concept of Free and Open-Source Software. I had very little understanding of how or why a patent would be needed or just how much controversy came with this ideology. So to be able to understand my assignment I had to understand what the issues were and get a clearer conception of business patents and monopolizing the market and the draw backs and cons.( Sean Michael Kerner ) What is Free Open-Source Software? Free is software at no cost and open source software is software that is liberally licensed by OSI that uses an open source list of open source licenses, that grant users the right to use and re-use, copy, study, modify, and improve its design through the availability of its source code, rather than having to purchase software or ask permission. The Free Software Foundation, an organization just for this type of software and they ensure that users have availability at completely no cost even when some companies try otherwise. This software’s focuses on the perceived strengths of its peer-to-peer development model and is used by many software packages. Students get to enjoy these software’s for modification and design capabilities, they create games redesign programs and a host of other things they would be not be allotted to change due to copyright laws .(cite: terrybollinger.com) Microsoft...

...Windows® vs. Linux It was inevitable that operating systems—and computer system in general—at least in the year 2012, are not anything like those envisioned by science fictionists, novelists, and screen writers of the early and mid 20th century. For the most part, they saw computers as a single entity one system controlling everything, like a giant brain reaching out and serving each end-user anonymously. And there were surely no “blue screens of death.” Computers today come in hundreds of flavors. Let’s say you want a tablet instead of a keyboard, no problem. Need to run a multi-million dollar company with an extensive database from home? No problem. Interfaces and operating systems and software applications and hardware upgrades and I/O devices provide each and every person on the planet a customized computer experience. We should thank capitalism for many of the technological advances that have come about over the past fifty years. After all, money has a tendency to flow to the products that make our lives the most enjoyable. Three of the most notable advances in computer history are servers (formerly known as mainframes), Microsoft Windows, and the Linux operating system. Each one in its own right could fill volumes. However, the objective of this paper is to simply highlight a few of the most prominent features each of these advances has to offer. We will start with the most notorious MS Windows®. Microsoft has been in the computer industry...

...| UNIX Performance Monitoring | My Research Paper | Student: Dwayne Blanchard Instructor: Professor Cliff KrahenbillAdvanced UNIX AdministrationMarch 3, 2012 | | | | | | The topic of my research paper will be on UNIX performance monitoring. The reason for choosing this topic is for personal understanding on how much UNIX performance monitoring differs from the monitoring of Windows based computers. This research paper is not to compare the two systems but to gain an understanding of how UNIX monitors performance. I don’t have any personal experience with working with UNIX systems, but as always eager to gain insight of different operating systems. The first thing I would like to discover is some of the common performance problems encountered caused by software, hardware and the combination of the two, the different terminologies associated with the processes via hardware or software, and finally what different utilities are used for monitoring these problems. We all know that UNIX has been around since the early 1970’s and the developments of performance tools have been around for a long time to enable system administrators in tuning systems for optimal performance. Operating systems performance problems normally involves process management, memory management, and scheduling. The object of performance on UNIX based systems is to determine the amount of time the operating system spends during scheduling...

...MIS Mini-cases -- 1 of 30 Cases for Use in Management Information Systems MIS Mini-cases -- 2 of 30 MIS Mini-cases -- 3 of 30 Case 01 -- Freeway Ford You are a management consultant working for Franklin Absolom, the majority stockholder for a group of 10 automobile dealerships. He has asked you to spend several days at Freeway Ford, a dealership that is not performing up to its potential. You are not to go ―looking for trouble‖: instead, your assignment is to find ways to help management at the dealership take advantage of opportunities. One day while you are talking with James Kahler, the sales manager for Freeway Ford, you realize that the dealership only uses transaction processing systems—it is not realizing the full potential of the information it has gathered for managerial decision making. For example, Freeway Ford knows the purchase date and owner of every car it sells, but it never contacts owner about routine maintenance. Freeway Ford know that people who purchase a new car generally trade it in for another new car 3 to 4 years later, but the dealership does not contact these previous customers. Another opportunity comes from used car purchasing and sales. Every car has a vehicle identification number (VIN), and the dealership uses this number to check for known problems with a used car before it makes a purchase. A data bank of car insurance claims histories and major repairs is kept on a set of CDs that is sent to the dealership each month. At the...

Being that the company envisioned is, at this point, just a blueprint in our minds we will have to start from the absolute beginning with cost, performance, low downtime, training, and efficiency in mind. Step by step we will come closer to our end goal of a relevant architecture for a turnkey establishment that will continue into the next generation of technological advancements. With cost in mind either an open source operating system or volume licensing are the best options available. Also focusing on limited required training to show staff how to utilize the system places Windows 7 as the best option with the most functionality and least concessions. Windows 7 shows many improvements over its predecessors but does not share the learning curve that Windows 8 does. Windows 7 should be continually supported by Microsoft for years to come, unlike Windows XP, again making it a viable option to become a standard within the company without requiring costly operating systems upgrades for some time. For the best cost...

...HOW SUCCESSFUL LEADERS THINK Leaders have the predisposition and the capacity to hold in their heads 2 opposing ideas at once. They’re able to creatively resolve the tension between those 2 ideas by generating a new one that contains elements of the others but its superior to both. This process of consideration and synthesis can be termed integrative thinking. It is this discipline that is a defining characteristic of most exceptional businesses and the people who run them. Not every good leader exhibits this capability, nor is it the sole source of success for those who do. But integrative thinking tremendously improves people’s odds (possibilitats). Many great integrative thinkers aren’t event aware of their particular capability and thus don’t consciously exercise it. Opposable Thumb, opposable mind Red Hat faced what seemed like 2 alternative paths to growth. AS Red Hat looked to grow beyond its $1 million in annual sales, it could have chosen one of the 2 basic business models in the software industry. 1. classic proprietary-software model sold customers operating software but not the source code. These companies had wide profit margins because their customers, lacking access to the source code, were essentially locked into purchasing regular upgrades. 2. Free-software model: suppliers sold CD-ROMs with both the software and the source code.--> Prices were modest; and suppliers made money each time they assembled a new version from the many free updates...

...We look for lessons in the actions of great leaders. We should instead be examining what goes on in their heads – particularly the way they creatively build on the tensions among conflicting ideas. How Successful Leaders Thınk by Roger Martin 60 Harvard Business Review 1179 Martin.indd 60 | June 2007 | Alex Nabaum W E ARE DRAWN to the stories of effective leaders in action. Their decisiveness invigorates us. The events that unfold from their bold moves, often culminating in successful outcomes, make for gripping narratives. Perhaps most important, we turn to accounts of their deeds for lessons that we can apply in our own careers. Books like Jack: Straight from the Gut and Execution: The Discipline of Getting Things Done are compelling in part because they implicitly promise that we can achieve the success of a Jack Welch or a Larry Bossidy – if only we learn to emulate his actions. But this focus on what a leader does is misplaced. That’s because moves that work in one context often make little sense in another, even at the same company or within the hbr.org 5/2/07 8:11:11 PM _ / / / g g hbr.org 1179 Martin.indd 61 | June 2007 | Harvard Business Review 61 5/2/07 8:11:25 PM How Successful Leaders Think experience of a single leader.

...theories about so=ware engineering suggested by the history of Linux. I discuss these theories in terms of two fundamentally di:erent development styles, the “cathedral” model of most of the commercial world versus the “bazaar” model of the Linux world. I show that these models derive from opposing assumptions about the nature of the so=ware-debugging task. I then make a sustained argument from the Linux experience for the proposition that “Given enough eyeballs, all bugs are shallow”, suggest productive analogies with other self-correcting systems of selfish agents, and conclude with some exploration of the implications of this insight for the future of so=ware. 1 The Cathedral and the Bazaar Linux is subversive. Who would have thought even five years ago (1991) that a world-class operating system could coalesce as if by magic out of part-time hacking by several thousand developers scattered all over the planet, connected only by the tenuous strands of the Internet? Certainly not I. By the time Linux swam onto my radar screen in early 1993, I had already been involved in Unix and open-source development for ten years. I was one of the first gnu contributors in the mid-1980s. I had released a good deal of open-source so=ware onto the net, developing or co-developing several programs (nethack, Emacs’s vc and gud modes, xlife, and others) that are still in wide use today. I thought I knew how it was done. Linux overturned much of what I thought I knew. I had been preaching...

...MODULE 1 Operating Systems There are three main operating systems in use today: Linux: Linux is an open source program available for free. “Open source” means that anyone who has the knowledge can improve the code, add functionality to the code, and modify the code to make it better. The only requirement is that you cannot sell it—you must give away your version for free. Linux is a subset of UNIX and is used more as a server OS than as a client. MAC: MAC has been a favourite of a select group, primarily those creating graphical arts, images, and video. In recent years, the MAC OS has become compatible with Intel processors. This has made the MAC computer system compatible with industry standard software, while the hardware has remained proprietary. The MAC OS commands approximately 8 percent to 15 percent of the OS market, while Linux has around 2 percent. Windows: Windows has approximately 82 percent to 90 percent of the market share. Windows XP is becoming the legacy version of the Windows OS, although it holds about 38 percent of the market share. Windows Vista did not fair too well on its release and now occupies only about 13 percent of the market share, while Windows 7 claims 30 percent of the market share. 1 NT1110: Module 6 Troubleshooting and Networks Final Exam Preparation Recap MODULE 2 Input and Output Devices I/O ports are primarily located on the back of the computer, though a few ports may be located on the front as well.
