Andrew File System essays

Andrew File System essays The Andrew File System (AFS) is a distributed network file system that enables files from any AFS machine across the country to be accessed as easily as files stored locally. It is an enterprise file system designed for use in a distributed environment on multiple computing platforms. AFS allows users on various types of computers to access the same file system. To a casual UNIX user, AFS disk space looks like a regular local disk; to Windows and Mac OS X users, it looks like a normal network drive. So with a single namespace and Kerberos authentication, AFS allows a user to log into any machine participating in the DCI and be presented their files and/or applications. AFS is composed of cells, with each cell representing an independently administered portion of file space. Cells are composed of two types of machines: fileserver and client. Fileservers are machines that typically store and control the files. A client machine accesses the files. Cells connect to form one enormous UNIX file system under the rootafs directory. PSC organizes and maintains the disk space associated with the cell psc.edu. One can access your PSC AFS space from most of PSC's machines, and can also make your directories accessible to users from any other AFS machine at any remote site. Like any network application, AFS has two components, a client and a server. The client component resides on each machine that wants to use AFS. This client asks the server for files stored in AFS and the server sends the file to the client over the network. The client then presents the file to the user as if it were local to the machine. When the user makes any changes in AFS space, such as creating a new file, saving a file or deleting files, the client sends the information to the server where updates occur. AFS speeds this process up by using disk caching. The AFS client keeps pieces of commonly used files on local disk. When the user asks the AFS client ...

Les Miserables essays

Les Miserables essays Many beliefs exist about redemption and the pursuit of such a divine principle. In Victor Hugos Les Miserables, JeanValjean seeks redemption and deliverance from his past sins by acting as a savior of underprivileged citizens in Paris. However, one must also explore the character of Javert, for these men ultimately pursue redemption. Both men obey the duties of their conscience, and both must make sacrifices, yet one man receives deliverance from his sins, and the latter, Javert, is overcome by them. These two men differ only in their interpretation of duty, demonstrating that merely abiding by ones conscience cannot always equal redemption. While seemingly good, Javerts actions spur from motives of none but Javert, and as such, render the foundation for greater injustices. The scruple of Javerts actions early became duty alone, and late into Javerts life duty remains his only dictator. Javerts ideal was not to be humane, not to be great, it was to be reproachable, and perform a duty to society that involves ridding the Parisian world of scum, or what he denounces as such (1324). The fact of the matter remains that with every hour and every action encompassed in this mans life, duty never exists as his primary concern, it exists as his only concern. Furthermore, when confronting the first and only dilemma of his conscience, Javert questions, Is there anything in the world besides tribunals, sentences, police, and authority? (1321). Such extreme moral conformity to the dictates of ones chosen conscience shields the beholder from all truths but ones own, and in the case of Javert, this singular conformity becomes the g reatest source of the purest selfishness known to man. Javert dutifully follows his conscience, which has impurities of great consequence, therefore all actions of Javerts doing have great consequence. This cause-effect reaction ma...

Examples and the Definition of Imagery

Examples and the Definition of Imagery Imagery is vivid descriptive language that appeals to one or more of the senses (sight, hearing, touch, smell, and taste). Occasionally the term imagery is also used to refer to figurative language, in particular metaphors and similes.According to  Gerard A. Hauser, we use imagery in speech and writing not only to beautify but also to create relationships that give new meaning (Introduction to Rhetorical Theory, 2002). Etymology From the Latin, image Why Do We Use Imagery? There are a lot of reasons why we use imagery in our writing. Sometimes the right image creates a mood we want. Sometimes an image can suggest connections between two things. Sometimes an image can make a transition smoother. We use images to show intention. (Her words were fired in a deadly monotone and she gunned down the three of us with her smile.) We use imagery to exaggerate. (His arrival in that old Ford always sounded like a six-car pileup on the Harbor Freeway.) Sometimes we dont know why were using imagery; it just feels right. But the two main reasons we use imagery are: To save time and words.To reach the readers senses. (Gary Provost, Beyond Style: Mastering the Finer Points of Writing. Writers Digest Books, 1988) Examples of Different Types of Imagery Visual (Sight) ImageryIn our kitchen, he would bolt his orange juice (squeezed on one of those ribbed glass sombreros and then poured off through a strainer) and grab a bite of toast (the toaster a simple tin box, a kind of little hut with slit and slanted sides, that rested over a gas burner and browned one side of the bread, in stripes, at a time), and then he would dash, so hurriedly that his necktie flew back over his shoulder, down through our yard, past the grapevines hung with buzzing Japanese-beetle traps, to the yellow brick building, with its tall smokestack and wide playing fields, where he taught.(John Updike, My Father on the Verge of Disgrace in Licks of Love: Short Stories and a Sequel, 2000)Auditory (Sound) ImageryThe only thing that was wrong now, really, was the sound of the place, an unfamiliar nervous sound of the outboard motors. This was the note that jarred, the one thing that would sometimes break the illusion and set the years moving. In those other summertim es all motors were inboard; and when they were at a little distance, the noise they made was a sedative, an ingredient of summer sleep. They were one-cylinder and two-cylinder engines, and some were make-and-break and some were jump-spark, but they all made a sleepy sound across the lake. The one-lungers throbbed and fluttered, and the twin-cylinder ones purred and purred, and that was a quiet sound, too. But now the campers all had outboards. In the daytime, in the hot mornings, these motors made a petulant, irritable sound; at night, in the still evening when the afterglow lit the water, they whined about ones ears like mosquitoes.(E.B. White, Once More to the Lake, 1941) Tactile (Touch) ImageryWhen the others went swimming my son said he was going in, too. He pulled his dripping trunks from the line where they had hung all through the shower and wrung them out. Languidly, and with no thought of going in, I watched him, his hard little body, skinny and bare, saw him wince slightly as he pulled up around his vitals the small, soggy, icy garment. As he buckled the swollen belt, suddenly my groin felt the chill of death.(E.B. White, Once More to the Lake, 1941)Olfactory (Smell) ImageryI lay still and took another minute to smell: I smelled the warm, sweet, all-pervasive smell of silage, as well as the sour dirty laundry spilling over the basket in the hall. I could pick out the acrid smell of Claire’s drenched diaper, her sweaty feet, and her hair crusted with sand. The heat compounded the smells, doubled the fragrance. Howard always smelled and through the house his scent seemed always to be warm. His was a musky smell, as if the source of a mudd y river, the Nile or the Mississippi, began right in his armpits. I had grown used to thinking of his smell as the fresh man smell of hard work. Too long without washing and I tenderly beat his knotty arms with my fists. That morning there was alfalfa on his pillow and cow manure embedded in his tennis shoes and the cuffs of his coveralls that lay by the bed. Those were sweet reminders of him. He had gone out as one shaft of searing light came through the window. He had put on clean clothes to milk the cows.(Jane Hamilton, A Map of the World. Random House, 1994) Observations The artists life nourishes itself on the particular, the concrete. . . . Start with the mat-green fungus in the pine woods yesterday: words about it, describing it, and a poem will come. . . . Write about the cow, Mrs. Spauldings heavy eyelids, the smell of vanilla flavouring in a brown bottle. Thats where the magic mountains begin.(Sylvia Plath, The Unabridged Journals of Sylvia Plath, edited by Karen Kukil. Anchor, 2000)Follow your image as far as you can no matter how useless you think it is. Push Yourself. Always ask, What else can I do with this image? . . . Words are illustrations of thoughts. You must think this way.(Nikki Giovanni, quoted by Bill Strickland in On Being a Writer, 1992) Pronunciation IM-ij-ree

Control Room Movie Review Example | Topics and Well Written Essays - 1000 words

Control Room - Movie Review Example However, this movie, Control Rooms, reveal a different side to the facts, the film reveals the extent to which the staff and reporting crew of the Media network had gone to convey the truth behind the sugar-coated waged war against the innocent civilians of Iraq (Samuel-Azran 73-89). Thus, in my opinion, in spite of its sketchiness, the movie delivers the message of its theme explicitly and indirectly, that touches the very cords of the hearts of sensitive humans. 2. To what extent the documentary might change your perception on the war in Iraq? I agree to Ty Burr (2004) when he says, â€Å""Control Room" is like an open window that sucks the smog out of the room. Clear-sighted and fair-minded, sympathetic to everyone except Saddam Hussein and the topmost level of the US government, this modest yet necessary documentary digs into the tussle between bias and balance in modern journalism and sends you out debating where one side's reporting becomes the other side's distortion.† This movie has changed my perception of war in Iraq to a greater extent. Earlier I had taken this military act to be against a brutal and killing enemy who had a monster like image in my imagination. Never had I considered the people dying there to be humans. I had always regarded their execution as a winning ‘mission accomplished’. ... If US had to wage a war against Saddam Hussain, it must have had find another way. To kill millions of people in the name of execution of their tyrannical ruler is to add inflict on injury. These people were already suffering and the military invasion had destroyed whatever they had managed to save so far. Truly, I am impressed and affected by the reporting of Al-Jazeera now as â€Å"†¦the station has revealed (and continues to show the world) everything about the Iraq War that the Bush administration did not want it to see† (Varma, 2004) 3. Critically identify the strengths and weaknesses of the video. The video, Control Room, is no doubt a marvelous and daring act done by Noujaim. The movie reveals hidden truths and passion for reality that is shared by all the journalists with living conscience. She has focused the role of the Qatar based media network, Al-Jazeera, which had covered the gruesome details of the happenings in Iraq. This particular network had sent its co rrespondents in Baghdad and other areas where they had covered the live details of the bombarding and shelling on the innocent civilians for which US government had blamed it to be a pawn in the hands of propagandist lobby of Arabs. However, the video exclusively reveals the false facets of the media world and this particular aspect makes this movie strong and effective. Moreover, Noujaim has just offered details of what happens behind the camera in a news agency network. All the interviews are taken in a bias free and impartial manner and the conclusion is left to the watcher. She has not tried to force her own ideas on the people; she has just captured with her camera what she found. â€Å"In the spirit of welcoming all information, she refuses to draw conclusions--these are left to the

Lifespan Development and Personality Paper Essay - 1

Lifespan Development and Personality Paper - Essay Example In addition, alcohol, drugs such as cocaine, lead, pesticides can damage sperm and cause children wit congenital defects. If the mother consumes alcohol during pregnancy, then the alcohol crosses the placenta and can result in children with ‘fetal alcohol syndrome’. The kind of diet that a mother takes, drugs, both legal and illegal would effect the later development of the infant. Mothers who have a healthy life style give birth to well formed babies with the right development of limbs and brains. Tobacco smoking by pregnant women is seen to cause premature babies that have low birth weight and increase in fetal deaths. Such children also show increased behavior abnormalities and cognitive problems. Motor development is mainly due to natural maturity but it can also be affected by environmental influences such as disease and neglect. Children with alcoholic mothers or ones who are neglected show lesser inclination to learn motor skills and may grow up with learning disa bilities and other problems. Piaget showed that an infants intellect is different from an adult and that an infant begins at a cognitively primitive level and that intellectual growth progresses in distinct stages, motivated by an innate need to know. Three major concepts are important: schemas, assimilation and accommodation. Schemas are cognitive structures or patterns consisting of a number of organized ideas that grow and differentiate with experience. Assimilation is the process of absorbing new information into existing schemas and accommodation is the process of adjusting old schemas or developing new ones to better fit with new information. In the first few weeks of life, an infant has multiple schemas based on the innate reflexes of sucking and grasping. These schemas are primarily motor and may be little more than stimulus and response mechanisms and soon other schemas emerge as the infant starts eating solid food. Assimilation and accommodation are the two major

T-Mobile Essay Example | Topics and Well Written Essays - 2250 words

T-Mobile - Essay Example For example, as material resources such as buildings, equipment or machinery deteriorate or lose efficiency; or as human resources get older, or as skills and abilities become outdated. Some of this change can be managed through careful planning; for example, regular repairs and maintenance; choice of introducing new technology or methods of work; effective manpower planning to prevent a large number of staff retiring at the same time; management succession planning; training and staff development (Handy, 1993). A senior manager should take into account internal and external factors that influence the company. T-mobile can only perform effectively through interactions with the broader external environment of which it is part. The structure and functioning of T-mobile must reflect, therefore, the nature of the environment in which it is operating. Factors such as uncertain economic conditions, fierce world competition, the level of government intervention, scarcity of natural resources and rapid developments in new technology create an increasingly volatile environment. In order to help ensure its survival and future success T-mobile must be readily adaptable to the external demands placed upon it. External change drivers are caused by innovation rapid technological changes and innovations proposed by competitors within the industry. One of the major changes deals with the specification of goods which may be considered in terms of their design features and performance characteristics (Vonderembse, White, 2003). Together these measurements define what the item is and how it is intended to perform its purpose. Also, the specification of a transport may be expressed in terms of its "design" and performance. In this context design i.e. the nature of the transport, movement may be expressed in terms of the origin, destination and route of movement. Present day situation in T-Mobile USA is marked by two factor - specification, which is to do with the 'design quality' of service, and conformity, which is to do with the 'process' quality which is achieved are of particular importance to customers. Ultimately they are the two factors which determine the quality levels provided by T-Mobile USA to its customers. These two factors however are themselves determined by other factors. Service concepts are based on understanding the unique environment in which T-Mobile USA operate. Service concepts include improvement of communication, and the environment composed of all the individual services used for implementation of the group communication primitives. T-mobile planned organisational change is triggered by the need to respond to new challenges or opportunities presented by the external environment, or in anticipation of the need to cope with potential future problems. Major competitors of T-mobile, Sony and Samsung, recently develop a completely new model of portable mobile phones which goes ahead all models exciting on the market, that is why further technological development is an urgent need for T-mobile. This planned change represents an intentional attempt to improve, in some important way, the operational effectiveness of T-mobile. The basic underlying objectives can be seen in general terms as: modifying the behavioural patterns of members of T-mobile; and improving the ability of T-mobile to cope with changes in its environment. Internal change drivers The increasing need for change in T-mobile Corporation

Chlamydia Research Paper Example | Topics and Well Written Essays - 500 words

Chlamydia - Research Paper Example Further, this essay will zone in on ways to which the onset of this infection may delay and how to promote substantive productive health. According to numerous researches, Chlamydia is a relatively inactive infection with minimal visible alarming signs and symptoms. Despite this, some signs of the infection may include a burning sensation in women especially when excreting urine and to some extremes pain during sexual intercourse. In addition, women may experience the discharging of a heavy and abnormal discharge that may be scentless. On the other hand, a heavy whitish discharge may be visible in men and pain during the passing of urine is also a symptom that characterizes the infection. According to Kacian (2012), the prevalence of Chlamydia and other sexually related infections are high between the ages of sixteen and twenty. Further, it is a health threat especially to those with multiple sex partners within this age bracket. Additionally, pregnant women also serve as potential victims of the infection. Remarkably, Chlamydia is the most reported sexually related infection across the United States. In addition, sexually active women within this age bracket should also subject themselves to annual screening in order to increase the chances of early detection and treatment. Subsequently, the infection may lead to infertility especially in women if no medical intervention occurs. Further, if untreated the mother may pass on the infection to her unborn child which may in turn affect their ability to see (Kacian, 2011). Moreover, having Chlamydia also makes one susceptible to HIV once one exposes themselves to it (Baby Center, 2013). However, the infection is preventab le through the consistent use of condoms and also through abstinence, which is more effective. Therefore, screening of pregnant mothers is vital in the prevention of blindness in newborns as result of this infection (Healthy People, 2012) Mostly, the prevention of contracting this
