Software Testing Essay -- Technology Computers Papers

Software Testing Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. â€Å"Software testing is arguably the least understood part of the development process† and is also a â€Å"time-consuming process that requires technical sophistication and proper planning† (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of software testing, and then to examine the techniques, procedures and tools used to apply this concept. This will enable the user to realize the problems faced by software testers and the importance of software testing. Software testing is the â€Å"process of executing a software system to determine whether it matches its specification and executes in its intended environment† (Whittaker 71). It is often associated with locating bugs, program defects, faults in the source code, which cause failures during execution that need to be removed from the program. Locating and removing these defects is called debugging, which is different from the testing that establishes the existence of these defects. Specifications are crucial to testing because they identify correct behavior so that software failures corresponding to incorrect behavior can be identified. Failures can vary in their nature ranging from wrong output, system crash to systems using too much memory or executing too slowly.

These cause highly infectious diseases such as – diarrhea, malaria, cholera, jaundice, plague etc. If we follow clean sanitation and use purified water then we can easily control and avoid many of the above diseases.

Night Essay

Compare the hanging of the â€Å"youth from Warsaw† and the hanging of the â€Å"sad eyed angel† and explain, using evidence from there and elsewhere in Night, why Elie Reacted differently to the two hangings. Elie Wiesel’s Night is a memoir of his horrifying childhood experiences of suffering as a Jew in the concentration camps. Eliezer was found to suffer in many camps, and during this time he witnessed the daily sufferings and deaths of many humans. His faith faltered as a result, and after so much pain he grew apathetic to the withering away of mortal life. By the end of the book nothing really surprises Elizer anymore because he knew anything could happen at any moment. However, Eliezer’s reaction towards hanging of the â€Å"youth from Warsaw† was different from the hanging of the â€Å"sad eyed angel. † Eliezer’s faith faltered daily when he witnesses the death of many innocent lives including the hanging of the youth from Warsaw, but he never loses his hope or questions the existence of God until he witnesses the hanging of the â€Å"sad eyed angel. † Eliezer witnesses many death during his time in concentration camps, and he never wept once, even when he witnesses the hanging of the youth from Warsaw. This young boy is described as tall and strong. Supposedly, he had stolen something during the alert in the concentration camp. Looking back at his execution, Eliezer expresses his feeling about the hanging saying that it â€Å"upset him deeply† (Wiesel 62) in a way quite distinct from his knowledge of the thousands who died daily in the camps. Elizer was disturb by the hanging because he did not lost all of his faith and hope, he still have humanity so that’s why he feels upset when he witness people die, deep in his heart faith and hope were just broken, now after witness the hanging of the youth from Warsaw he found the broken pieces of hope that is why that evening after the execution he finds â€Å"the soup tasted better than ever† (Wiesel 63). Another reason that Eliezer finds the soup taste better is because he was actually grateful that it was not him or his father toward the execution. Elizer realize that death is everywhere in concentration camp, and it could be either him or his father next time standing on the gallows. He is thankful that he still alive at that moment and can is still eating his ration of soup, although he knows that he could be in line next to get hang in the gallows. Eliezer also felt the youth from Warsaw brought the death on themselves. He realizes that there are rules in the concentration camp that you can never disobey, if you break the rules in the camp, you will be killed. Where is merciful God, where is He? †(Wiesel 64) It was another day when Eliezer return from work and roll call begins. There were three gallows for three prisoners that are going to be hang on the gallows for conspiring to blow up the electric power station, but among the three prisoners there is a little pipel in the middle, the sad eyed angel. At every hanging, no one in the audience will ever shed a tear or weep, but the hanging of the sad eyed angel affected not only Eliezer but many others. During the execution all eyes were on the child, the two men died immediately, but the child was too light â€Å"and so he remained for more than half an hour, lingering between life and death. † (Wiesel 65) The hanging pained Eliezer so much and it makes him wonder how God can be present in a world with such cruelty, he question the present of God and when he heard a voice saying â€Å"For God’s sake, where is God? † (Wiesel 65) he answers â€Å"Where He is? This is where –hanging here from this gallows†¦Ã¢â‚¬  (Wiesel 65). Following the death of the sad eyed angel Eliezer thinks that was the death of God as well. â€Å"That night, the soup tasted of corpses† (Wiesel 65), after witness the hanging of the sad eyed angel Wiesel finds the soup tasted like corpses and also like death, the death of God. The sad eyed angel represent a symbol of silent which God is presents as in the novel Night. God was a symbol of silence in the novel because when Eliezer and the other Jewish people cries out for God’s aid and mercy, their please were left unanswered. The God in Night did not save them from cruelty and death, God has remained silence throughout the novel, so when the angel was hanged Eliezer’s relates the death of angel to the death of God, as he meant that God was hanging upon the gallows and had abandoned them. Eliezer realizes that the Nazis were coming closely to destroy his faith in God and so he was unable to enjoy anything because he thinks that life, hope, and joy could not be reach because all goodness had been destroyed. â€Å"I’ve got more faith in Hitler than in anyone else. He’s the only one who’s keeping his promises, all his promises to the Jewish people† Wiesel 81) Hitler the ultimate evil was conquering the good Jewish people every day through death and destruction. To Eliezer there was no hope for life and no chance for survival. He thinks God had abandoned them because there seems to be no end to evil. After witness the hanging of the sad eyed angel, Eliezer was constantly being reminded of death, he feels like death was everywhere in the camp, and when he were forced to watch the hanging of the sad eyed angel, which appeared to be innocent and full of hope, he feels that he was forced to watch innocence and hope die in front of him. As Eliezer watched the young pipel struggle between life and death he felt that the boy was innocent and he did not deserve to suffer. Eliezer and the young pipel were around the same age, so when he witnesses the hanging of the young pipel he felt as he shared the pipel’s pain and suffering and that he was suffering from a slow painful spiritual death as well. The hanging of the young pipel pained Eliezer so much because he knew he could not rescue him. In Elie Wiesel’s Night the author present a significance of the hanging and the brutal elements of the surroundings in the concentration camp. He express that evening â€Å"the soup tasted better than ever† (Wiesel 63) after he witness the hanging of the youth from Warsaw, and yet after he witness the hanging of the sad eyed angel â€Å"the soup tasted of corpse. † It was trying to present how Eliezer’s slowly loses his hope and faith in God. Eliezer’s faith was being challenged under such brutal condition, and many do not get their beliefs put to the test in such extreme condition as Eliezer did, and this leads Eliezer to question his faith. The meaning of hanging in this novel represent the bad conquers good, death and evil become apparent. The goodness that had been present prior to concentration camp had been destroyed through death, evil and abandonment. Every killing that Eliezer witness deteriorated his faith and finally after witness the sad eyed angel, it was the end of hope for Eliezer, he finally understood the murderous nature of concentration camp, and he could not walk away unaffected by the hanging. At last, Eliezer walked away as a completely different person than how he entered.

Nicholas Carr vs Steven Pinker Essay

There is no doubt about it that in today’s generation the Internet is one of the best phenomenal creations invented. By simply having a computer, cell phone, tablet, ect, anyone and everyone can access the Internet. But can this powerful yet simple creation have a drastic effect on how the new generation operates today? The entire world is rapidly becoming obsessed; everywhere you look you’re bound to see something related to the Internet. Search engines, texting, twittering, blogging; to name a few. We have all heard of at least one of those internet friendly applications. But can those applications become too friendly to the point where they are a distraction to the young mind? Can those applications hinder how the human brain functions? There are numerous arguments, views and statements regarding such an important question. Two writers that I researched share their opinions and views based off of how the internet has affected others intelligence today. These two writers go by the name of Nicholas Carr and Steven Pinker. Without having any knowledge of what the articles are about one only needs to read there titles to distinguish the differences between the two. Where as Nicholas Carr’s article is titled, â€Å"Does the Internet Make You Dumber? † Steven Pinker’s article is titled, â€Å"Mind over Mass Media†. Both writers have completely different types of titles but one can assume that they are responding to the same subject. After thoroughly reading both articles, Nicholas Carr and Steven Pinker have completely different views when it comes down to how the internet influences others. Firstly, Nicholas Carr addresses heavily how in fact the internet does make you dumber. All throughout the article he gives examples of studies aimed at showing how the internet doesn’t positively contribute to the brain at all. As stated from the article Nicholas Carr explains how â€Å"People who read text studded with links, comprehend less than those who read traditional linear text. How, people who watch busy multimedia presentation remember less than those who take in information in a more sedate and focused manner†. All of which are pretty apparent that the effect that the internet has on the mind is quite drastic. On the other hand, Steven Pinker’s article strongly disagrees at the fact that the internet affects the human brain. His defensive points primarily explain how without the internet a lot of today discoveries and new inventions wouldn’t be possible. Also he defends the fact that distraction or addiction is not a new phenomenon. Regardless of whether the internet is a popular utility or not, distraction would still be an occurring issue. It is quoted: â€Å"If electronic media were hazardous to intelligence, the quality of science would be plummeting. † Also, â€Å"Yes the constant arrival of information packets can be distracting or addictive, especially to people with attention deficit disorder. But distraction is not a new phenomenon. The solution is not to bemoan technology but to develop strategies of self-control as we do with every other temptation in life. † Steven Pinker is trying to get the reader to understand that the internet doesn’t essentially make you dumber but it does hinge at one’s attention span. Outside of the internet distractions are common everywhere. One can become distracted by their job, parents, work, internet, ect. Because of these interruptions Steven Pinker’s makes it known that all distractions require self-control. If one doesn’t have self control over an issue they will become addicted. Lastly my research wasn’t over. It wouldn’t be right if I didn’t get a third opinion to help provide some extra study. A third writer that I came across was a woman named Sherry Turkle. Sherry Turkle has written a popular novel titled â€Å"Alone Together†. In the novel Alone Together author Sherry Turkle explains a third completely different concern on how technology affects the average American. This concern is in regards to how individuals will end up alone together because technology has distanced face to face relationships. That society expects more from technology and less from each other. Over the years Sherry Turkle has examined how technology has jeopardized the true meaning of hands on communication. Although she does not mention how the internet may interfere with learning or brain capabilities she does still presents other exceptionally important factors. In conclusion, in comparison of the two primary articles that I researched I would ultimately have to agree with the Nicholas Carr piece. I feel as if the Nicholas Carr piece will convince more people. His article compared to Steven Pinker’s has a lot of legitimate studies and facts. His studies included one conducted at Cornell University, where they conducted the laptop experience, which compared the effect of students who studied utilizing the traditional method of the library and those who studied using the laptop for research, with the conclusion that those who studied using the library grades were higher; studies from Stanford where they conducted a multi-tasking trial, also, studies from the University of California in San Francisco where they conducted a brain experiment. Where, Steven Pinker’s article comes off as an opinion piece with little to no background information or supporting references. I would want to believe that the mind is in fact over mass media but Steven Pinker’s article doesn’t defend his title strongly at all. Thus, leaving me with the conclusion that the internet is a major distraction, can hinder how I use my brain properly, and can jeopardize my in person communication skills that I have available.

Law risk #7 Essay Example | Topics and Well Written Essays - 250 words

Law risk #7 - Essay Example The institutionalized peace and truce of God was then Christianized into Crusades. The people are given scriptural provisions that refer to peace and truce of God but these provisions are ‘to be controlled by the law of the church,’ which goes ahead to call for the Crusades (Munro 5-8). Urban justifies violence against the Muslim world. He calls upon ‘the shepherds to guard on all sides the flock committed’ to them for if they are not careful the wolf may carry the flock away, and God would reduce the reward stored for them. The justification is also evidenced when he tells the people that being the salt of the world, it is necessary for them to correct the wisdom of the foolish people, failure to which they would be denied the loving presence of God. He further urges that although the people have promised to keep peace amongst them, they have a greater task of applying the strength of their righteousness towards the brethren who live in Romania where the Turks and Arabs are attacking. The unjust, robbers and mercenaries are told by Urban to fight the barbarians (Thatcher

Project2 Essay Example | Topics and Well Written Essays - 1250 words

Project2 - Essay Example An FMCG company requires heavy capital investment because from product development to marketing and advertising, capital is necessary in every sector. Moreover, FMCG companies are no more limited to a particular geographic location; instead they are pursuing overseas ventures. Therefore, threat of new entrant at international market is relatively limited. P&G is one of the reputed FMCG companies and its brand, Head & Shoulders is well-recognized in the hair care industry. Consequently, it can be suggested that threat of new entrant is limited for the company and the product (Reuters, 2013). FMCG industry is one of those industries that are heavily vulnerable to substitution, as local as well as a number of international brands are taking entry in the industry on a regular basis. However, studies suggest that P&G is a global leader in the hair care segment and have more than 20 percent of market share thereof from Pantene and Head &Shoulders (Reuters, 2013). The company has invested significantly in marketing and brand building of Head & Shoulders. The outcome is that the brand image is spreading from that of a medicated shampoo to a mass consumer product. Head & Shoulders is often marketed using celebrity endorsement which has significant positive impact on consumer buying behavior. Therefore, it can be suggested that threat of substitute is relatively less for the product (Reuters, 2013). Purchasing behavior of consumers has significant impact on revenue of FMCG companies. However, consumer buying pattern is strongly influenced by number of competitors or substitute products and their prices within the industry. It was ascertained that consumers have relatively strong bargaining power as the choices in hair care products in large and are mostly from well-known brands such as Unilever, L’Oreal, Colgate-Palmolive and Johnson & Johnson. These companies are

Nikita Khrushchev & Cuban Missile Crisis Term Paper

Nikita Khrushchev & Cuban Missile Crisis - Term Paper Example Cuban Missile Crisis is an important historical event for its relevance to the cold-war era, as it is believed to be the most intense encounter between the then Superpowers, U.S and USSR. Since both countries had a nuclear capability, a direct encounter meant the most cataclysmic war in the history of global politics. For this reason it is important to draw a cause and effect relationship between variables in this context to analyze the important factors causing this event and the outcomes. Historically, most of the accounts presenting the Cuban Missile Crisis and its resolution rhetorically give due credit to the patient and the wisdom of JFK to have resolved the issue in time and avoid nuclear war. Many factors can be identified, for instance, the placement of U.S missiles in Turkey close to the vicinity of Soviet. Similarly, the Bay of Pigs incident caused a threat perception in the mind of Castro and in order to avoid a future attack, he sought assistance from the Soviets. Also, another reason can be understood in terms of the balance of power and the ambition of the Soviets to represent a superior vision in the world regarding the power and the image of the Soviet. Thus, as a result of these, along with many other factors Soviets placed Middle Range Ballistic Missiles in Cuba which stimulated the threat perception within the minds of the decision makers in the U.S. Consequently, JFK along with his advisors explored all available options to resolve the crisis, and agreed upon the option of the Naval Blockade, which they labeled as â€Å"Quarantine† which continued for 13 days.... Nevertheless, in my view, Khrushchev should equally be appraised, as he also took the matter very seriously and patiently communicated his terms and conditions to JFK. Thus, without appraising Khrushchev, even Castro, for their efforts in this regard the rhetoric remains incomplete. To analyze the event, its historical context needs to be discussed in detail. In this regard, the various long-term as well as short term objectives of the Missile deployment in Cuba by the Soviets can be studied, which will help us analyze the causes behind the event. The historical context of the event can be traced back to the U2 incident which occurred in May 1960, when U.S sent a spy plane into the vicinity of Soviet Union, which was both a breach in the security of the territory of the U.S.S.R, and a cause of building a trust deficit. Even after this event, despite the pressure from the hard liners, Khrushchev managed to stay calm and kept indicating his intentions of maintaining peace between the s uperpowers1. Preceding this dangerous event was the Bay of Pigs accounts which again proved to draw a line between the superpowers. In 1961, U.S made an attempt to overthrow Fidel Castro`s government in Cuba which eventually failed. U.S trained and triggered some Cuban rebels to overthrow Fidel in an operation, however the operation immensely failed. This led towards the shattering of the image of the U.S in the world, and it further boosted the confidence of the Soviets which encouraged them to take this step. 2Also, this event was an indication of the interest of U.S in Cuba which indicated that U.S fears that Cuba can later turn out to be problematic for the U.S. Also, U.S later posed various sanctions over Cuba which
