Analysis of Red Hat Linux Operating System Research Paper

Analysis of Red Hat Linux Operating System - Research Paper Example Among other innovations, such as the Anaconda graphical installer and the firewall configuration tool Lokkit, Red Hat is an established name in the open source operating system market space. This may be due, in part, to its appealing graphical interface for users and the accessibility of its programmer interface, which is intelligently presented. By reviewing this interface, as well as some advantages and disadvantages of the operating system, why exactly Red Hat is a respected name in Linux circles may become clearer. Red Hat is ostensibly based on the design principles of simplicity, robustness, and security (Cunningham & Cunningham, 2007). Simplicity refers to simple abstractions and simple components, which leads to faster and more efficient use of hardware resources. Red Hat exemplifies this characteristic by focusing on a simple desktop for users to customize. Robustness refers to the ability of a system to resist failure after the addition of a new feature or component. When a system is multiprogramming, it is ideal if the system does not fail because it cannot adequately distribute resources to handle the increased load. Red Hat, because it has been developed and re-released over nine versions, is incredibly robust in handling large memory loads. Lastly, Red Hat is based on a secure design, which means Red Hat has extended Linux’s reputation as a secure environment, primarily by buffering overflows integrated in the standard software stack, smartcard authentication support, and SELinux security. The Red Hat Linux desktop consists of GNOME and KDE, which offer a wide range of features. The KDE desktop for Red Hat (in Figure 1), features a main menu icon at the lower left, which is a red hat. The desktop includes a number of files and folders, depending on what software is installed on the user’s computer. KDE is very similar to the standard Microsoft Windows format for the central desktop, particularly in how the standard option places the taskbar at the bottom of the screen, with a main menu button at the lower left, and desktop icons arranged vertically along the left side of the desktop. KDE uses a file management and web browser called Konqueror, which is a standard setting in Red Hat installations. Lastly, the KDE Control Center window allows for additional customization of the operating system for the user. In contrast, the GNOME desktop for Red Hat Linux (in Figure 2) is slightly different from KDE (McCarty, 2004). The principal dissimilarity is GNOME’s use of Nautilus, which like Konqueror, is the default file manager and browser. Another notable difference is GNOME’s use of a drawer, which is a clickable icon that leads to links to other launchers. GNOME also features a â€Å"Start Here† facility that allows for other kinds of configurations, including changes to peripheral devices, default applications, themes, GNOME’s appearance, and so on. A Red Hat Linux user is given a choice between the KDE and GNOME desktop interfaces. Beyond the basics of Red Hat’s desktop and user interface, however, one finds a rich array of tools for a programmer to manipulate and control his or her machine. The Unix shell in Red Hat, like an MS-DOS window, allows the user to execute commands. Again, beyond the desktop and point-and-click interface, the Linux shell is actually more sophisticated. The major elements of the programmer interface

Why Is Desalination Becoming So Important?

Why Is Desalination Becoming So Important? Desalination is a technology which includes several processes that remove salt and other minerals from seawater to produce freshwater. In recent decades, this technology developed rapidly and becoming more and more popular around the world. This essay will focus on the effects of using desalination. It begins with the reason why this technology develop rapidly in the recent years. After that, some economic and environmental benefits and drawbacks of desalination will be analysed. Finally, give a conclusion. Water is a basic and crucial resource for survival and growth of life. We can not live without water. However, there is a research by Fiorenza (2002) shows that nearly one fourth of mankind is suffering from inadequate fresh water supply, both of quality and quantity. Considering water shortage concerns about 80 countries and has caused some serious results in many places, the water shortage phenomenon is becoming a serious global problem that affects peoples daily life and hindered the social development. Because of the increasing number of global population and expansion of both industrial and agricultural activities, the water requirement will increasing rapidly in a very near future. It is obviously that the traditional fresh water supply system can not meet the requirement any more. An alternative water supply option is need to help us deal with this problem. Water is so important for human beings, therefore, we have already developed many kinds of water supply systems. But all of them have a common problem and also the fatal problem is that they all need natural fresh water resources. The research by Khawaji (2007) illustrates that nearly 97% of the earthà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s water is seawater while another 2% is fresh water but locked in icecaps and glaciers. The available fresh water just accounts for about 0.5% of the earthà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s total water supply. Another point should be considered is human activities have polluted a large amount of fresh water resource. It means that all the traditional water supply systems just can use much less than 0.5% water resource. It is obvious that we can not just rely on these traditional water supply systems any more. Comparing with these traditional options, the desalination technology does not need natural fresh water resources, desalination equipment can prod uce fresh water from seawater. This technology give human beings an opportunity that we can use the majority of earthà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s water resource. This is really a revolutionary change that we need not rely on natural fresh water resources any more. Because of this unique advantage, desalination has developed rapidly in recent decades and playing an important role in many countries now. For example, according to research by Zhou (2003), in Saudi Arabia the desalination equipment produces more than 6,000,000 m3 of freshwater per day. This technology has become a reliable fresh water source for human beings. In fourth century BC, Aristotle found that when saltwater turns into vapor, salt and freshwater will separated. This was the first desalination theory and it has already been discoverd more than 2000 years. The previous analysis shows that desalination has a lot of advantages, but it can be questioned just used in recent years. It is because the former desalination technology cost too much and was not reliable enough. This is also the main reason why there are many critics against the use of desalination. However, the desalination technology has advanced a lot in the last 30 years, especially, the invention of multi-stage flash process and reverse osmosis. According to the research by Tsiourtis (2001) shows that 86% desalination factory use these two desalination processes now. In addition, these two methods are the most commercially important desalination technologies. Furthermore technological advances were made on the multi-stage flash (MSF) process (materials and process) and on reverse osmosis (RO), with improvement on the membranes and the energy recovery equipment. (qtd. Tsiourtis, 2001) So these technological advances in the last 30 years have driven down the cost of desalinated water very much. The figure 1 illustrats that the price of desalination shows a decreasing trend from 1988 to 2000. The total cost of desalination decreased from1.7$/m3 in 1998 to 0.7$/m3 in 2000. It is an acceptable price for many countries now and due to the decreasing trend, it can be predicted that the desalination will more cheaper in the future. The decreasing cost trend is just one economic benefit of desalination. Another reason is in some situations, desalination is a cheaper water supply option. For example, Chinas water resources are uneven distributed and many places in northern China are facing the water shortage problem. So, the government decides to build a long pipeline to transfer water from the Yangtze River to area in northern China. Research by Liu and Zheng (2002) shows the main canal would be 1150 km long. From the research by Kally (1993) we already find that the cost of transport is around 0.061$/m3 per 100 km. Therefore, it means that the cost of transferring water will more than 0.07$/m3. It is higher than using desalination, additionally, because of the desalination cost has fallen from 1.7$/m3 to 0.7 $/m3 and still keep an decreasing trend. There is no reason to believe that the trend will not continue in the future. So desalination also has its economic benefits in some situations. Desalination not only has economic benefits, but also has many environmental advantages. Firstly, compares with the water transport, desalination does not need so much pipeline and pumping stations. It means that less land will be occupied and less energy will be wasted in the transferring process. After that, because these traditional water supply options need fresh water supply, the overuse of surface water and groundwater has caused many serious consequences. For instance, the ground surface settlement happened in many places in China just because of the abuse of groundwater. Research by Chai et al. (2004) shows that due to the abuse of groundwater, surface surveys of land subsidence is 2 to 3 meters in the central area of Shanghai. Ground surface settlement is harmful to a buildings foundation and will cause dangerous results. However, desalinations resource is seawater, it will never limited and never will have these troubles. So, compare with some traditional water supply optio ns, the desalination system also has some of its own environmental benefits. From the above analysis we find that a desalination system has its own advantages no matter in economic and environmental aspects. But it is undeniable that this technology still has some drawbacks in both aspects. Firstly, the desalination process has a by-product called brine, What is a kind of water that contents double salt of seawater and also contains membrane cleaning chemicals and other chemicals used for scale and corrosion control(qtd .Tsiourtis, 2001). If we can not treat the brine well, it will cause serious pollution. Then there are some chemicals will be used in the desalination process. It also will cause some pollution. After that, noise pollution is another problem, the noise produced by these machines will trouble people. Furthermore, comparing with other water supply options, desalination still a little expensive than these traditional ones in normal situations, many countries can afford this technology as the option to solve their water shortage problems. Overall, desalination is already becoming a very important water supply option, especially in these energy-rich, dry and lack of freshwater resource areas, such as these Middle East countries. This technology give human beings an new option to solve water shortage problem. Although, this technology still have some problems but because of its own advantages and the trend of desalination technology development, we can believe that desalination will have a bright future. This technology will play an more important role in future. Word count: 1294

Slavery and the Jamaican Maroons Essay -- Jamaica, Africa

The introduction of black slaves in the western world was the beginning of a new culture, more economic wealth and prosperity for whites and for blacks a life of poverty, enslavement and oppression. The life and times of the Jamaican Maroons is a story of an indomitable foe, a people whose survival depends on their wit and tenacity, form a part of this terrible saga in the history of blacks in the New World and where we are today. The struggle of the Maroons of Jamaica against the British colonial authorities, their subsequent collaboration with and betrayal by them. A story that took a circular voyage from West Africa to Jamaica, then to Canada and in the end returned to Africa. The Maroons of Jamaica originally came from West Africa. Some of them were IBO, a tribe from eastern Nigeria. The slave trade between 1590 and 1840 concerned three different cultures from three different continents involved in an elaborate system of barter in enslaved Africans. Europeans comb African countries looking for gold, ivory, spices and cheap labour for their plantations in the Americas; traveling routes first navigated in the 15th century. The Henrietta Marie was typical of the small merchant ships and traders that ply the Atlantic on their way to the Americas and the West Indies at the turn of the 18th century. In 1699, the ship left the port of London on her second slaving voyage, carrying cargo of European manufactured goods for trade in West Africa. She journeyed to the African coast where her cargo is exchanged for enslaved Africans and ivory, from there the ship sailed to Jamaica, where the captives is exchanged for sugar and logwood. Laden with new world goods, the Henrietta Marie! Began her long and ardours voyage home to London,... ... Africans, but a life born of necessity. Indeed, the early Maroons were "thorns and pricks" in the side of the British, they plunder and burn plantations, captured slaves and killed British soldiers who ventured out too far into the woods. The Maroons victories against the British were so numerous that in April, 1656, the British Governor D'Oyley reported "it hath pleased God to give us some success against the Negroes. A plantation of theirs beeinge (sic) found out, wee (sic) fell on them, slew some, and spoiled one of their chief quarters." In another skirmish the British soldiers killed "seven or eight â€Å"negroes" but the Maroons retaliated by ambushing and killing forty soldiers. In a letter to John Thurloe, Major Sedgwick said, "In two daies (sic) more than forty of our soldiers, were cut off by the negroes as they were carelessly going about their quarters."

Growing Up in Apple Valley :: essays papers

Growing Up in Apple Valley Growing up in Apple Valley is an indelible experience not too many people go through. Every time I say I’m from Apple Valley people always don’t know where Apple Valley is. I usually say that it is off the Interstate 15 freeway, like you are heading to Las Vegas, right next to Victorville. Then they finally realized that they have heard of Apple Valley. It is very indecipherable to say exactly where Apple Valley is. People constantly think that Apple Valley is simply a big desert and there are only poor quality people who live there. The truth is Apple Valley is a very beautiful place to live. Apple Valley has some imperfect parts of the town and there are its good parts. I feel that the good parts overcome the bad parts. I have seen a lot of other cities that are much worse and they still have a well-rounded reputation. For instance, the High Deserts biggest city, Victorville. Victorville has much more crime than Apple Valley, much more pollution, and many more troublesome citizens. Victorville also has a lot more traffic on their streets because there are so many more people. Apple Valley has about two-thirds the amount of population Victorville has and with that comes less traffic on the roads. Less traffic on the roads means less smog pollution, less traffic accidents, less paramedic’s the city has to hire, and less the city had to pay out towards medical response. Most cities want to save money so they might be able to spend more money on the city or even cut some taxes. The less smog pollution is a really pleasant factor that comes with living in Apple Valley. It is nice to know that you are breathing in fresh air, not air that is dirty and full of pollution. Apple Valley really doesn’t have much to do for kids and teenagers. That is probably one of the main complaints about Apple Valley. The way I see the situation is you can always drive somewhere and the fun really isn’t that long of a drive away.

How Does Shakespeare Present Feelings of Love

How does Shakespeare present strong feelings about love in ‘Romeo and Juliet’ and ‘The Merchant of Venice’ In Romeo and Juliet and The Merchant of Venice There are many examples of strong love. The two most prominent examples of strong love are romantic love and unrequited love. In Romeo and Juliet, there appears to be more examples of unrequited love than that of romantic love, despite the main theme of the play being the romantic love between Romeo and Juliet.The unrequited love between Romeo and Rosaline is significant, as it opens the debate of whether or not Romeo’s love for Juliet is sincere. At the beginning of the play, Romeo claims to be in love with Rosaline, saying to Benvolio â€Å"In sadness cousin, I do love a woman,† in Act 1 scene 1. The love he feels for her is a sad and longing love, for she does not feel the same. The likeliness of Romeo’s love being just infatuation is high, as he loses his love for Rosaline quickly a fter merely laying eyes upon Juliet at the Capulet’s ball, â€Å"O she doth teach the torches to burn bright! In this quote and the continuation of the speech, he explains how she is a â€Å"rich jewel†, burns brighter than the torches and beauty is not a strong enough word to describe her looks. As he finds his new love in Juliet so quickly, you could argue that it is only infatuation as he sees her at the party for only her looks, as he did with Rosaline earlier on. Another notable example of unrequited love is Paris and Juliet. In act 1 scene 3, Lady Capulet and Nurse are talking to Juliet about Paris’ love for her. They are trying to convince her to want to marry him as she does not have a choice over whether she actually does or not.They continuously say what a great man he is â€Å"He’s a man of wax† (possibly meaning that Paris is so perfect, he could be made of wax) and â€Å"Read o’er the volume of young Paris’ face, and fi nd delight writ there with beauty’s pen. † They imply that Paris does in fact love her from the line â€Å"Speak briefly, can you like of Paris’ love? † In the part of the scene where they are describing Paris to her, Shakespeare uses a lot of reference to books, possibly implying he is a man of intellect, so he is not just looks.In the time that Romeo and Juliet was set, books would’ve been owned only by the rich and educated, a lot of books were also handwritten with beautiful handwriting, so with use of metaphors of books, Lady Capulet and Nurse were comparing him to something of privilege, wealth, and beauty. Despite their efforts, Juliet does not warm up to the idea of marriage as she does not know Paris, saying â€Å"It is an honour that I dream not of,† and â€Å"I’ll look to like, if looking liking move. But no more deep will I endart mine eye than your consent gives strength to make it fly. The romantic love between Romeo and Juliet is considered to be true love. It appears to be love at first sight when they see each other at Capulet’s ball, and after their first kiss, they find out they are each from the feuding families. They are shocked and devastated when they find that out as they realise they cannot be together, showing deep feelings and devotion from the start. Throughout the play, they find ways to see each other and get married. Juliet seems to truly love Juliet, as she still trusts him even after he has killed her cousin, Tybalt.Also, at the beginning of the play, Juliet appears shy and reluctant to speaking much, but when she meets Romeo, she speaks as much to him as he is to her and in the same style. She has very complex thoughts about him, showing her love is sincere and well thought out. And when she finds out he is a Montague, he thoughts are for his safety. She trusts Romeo a great deal, as she asks only for his word of love, needing no proof. This differs particularly from the romantic love between Portia and Bassanio because not only does she give him the ring as proof of her love, she feels she has to test his loyalty with it.But Juliet does not doubt Romeo. In order for the two of them to get together, she very bravely, goes through with Friar Lawrence’s plan, meaning she disobeys her parent’s wishes. When she awakes from her sleep, she finds Romeo dead beside her. She kills herself as she cannot imagine living her life without Romeo, which is the same reason Romeo killed himself. They loved each other so strongly they were willing to give their lives for each other. Throughout the play, Romeo and Juliet show devotion, loyalty, and love.In The Merchant of Venice, there are more examples of romantic love than that of unrequited love, although it is arguable that not all examples of romantic love are genuine. The first example of romantic love is that of Jessica and Lorenzo. In the play, Jessica is Jewish and Lorenzo is a Christian, meaning that there love is forbidden. Jessica gives up her faith and becomes a Christian so her and Lorenzo could be together. The love of these 2 is much like the love between Romeo and Juliet. Romeo and Juliet both give up their lives as they could not be together, and Jessica betrays er father by becoming a Christian, much like Juliet betrays he parents by marrying Romeo. Both of these are examples of forbidden love. The romantic love between Portia and Bassanio is one that can be debated. When Bassanio first talks of marrying Portia he says â€Å"In Belmont is a lady richly left/and she is fair. † From this quote you could presume he is only interested in Portia for her money, as he is in great need of it at that moment. But when he has to pick between caskets he says that he is â€Å"tortured not knowing if he can marry her or not†, but he could just be putting on an act.He leaves Portia almost immediately to return to Venice and help Antonio, he says he will not sleep u ntil he sees her again, which, again, could be an act, though he appears to act more sincere at this point. Before he leaves, Portia gives him a ring as a token of her love. Later on, he is very reluctant to giving the ring up to Balthazar when he asks for it as payment at first, but when Antonio tells him to he gives it up immediately. At the end of the play, he apologizes and says he’ll spend the rest of his life devoted to Portia. Portia’s love to Bassanio appears to differ greatly from that of Bassanio to Portia.When Bassanio chooses the right casket, she is delighted, and is very worried that she would not live up to his expectations. â€Å"I might in virtues, beauties, livings/ exceed account† When first speaking to him, she also seems to give herself to him. â€Å"Myself and what is mine, to you and yours/ is now converted. † She does not seem to be as independent as before. She could’ve been suspicious of the legitimacy of Bassanio’s love from the start, she could’ve already been planning to test him before she gave him the ring. She also offers to pay Antonios debt twice over, just because he is a friend of Bassanios.An example of unrequited love is Antonio’s strong feelings towards Bassanio. Antonio is very happy to lend Bassanio money even though he is already in Antonios debt and Antonio would have to borrow money from somewhere else to do so. When Solario describes their friendship, he says â€Å"I think he only loves the world for him† â€Å"Him† being Bassanio. When Antonio believes he is going to die, he tells Bassanio â€Å"say how I loved you† and seems glad that he is paying for Bassanio’s debt with his life, instead of Bassanio having to do so himself. The last example of unrequited love is the love between Nerissa and Gratanio.When Gratanio marries Nerissa, the marriage also depended on whether or not Bassanio chose the correct casket, so his love may not b e sincere, and more forced. For if the incorrect casket had been chosen, would he still have loved her so dearly? Would he have even still loved her at all? In conclusion, Shakespeare puts many aspects of strong feelings in the form of love into these two plays, and presents each of them in a unique and individual way, leaving much room for interpretation. He uses expressive language, many great examples of tone and exchange of speech to emphasize these facts.
