Digital Fortress Chapter 34

Susan sat alone in Node 3, waiting for her tracer. Hale had decided to step outside and get some air-a decision for which she was grateful. Oddly, however, the solitude in Node 3 provided little asylum. Susan found herself struggling with the new connection between Tankado and Hale. â€Å"Who will guard the guards?† she said to herself. Quis custodiet ipsos custodes. The words kept circling in her head. Susan forced them from her mind. Her thoughts turned to David, hoping he was all right. She still found it hard to believe he was in Spain. The sooner they found the pass-keys and ended this, the better. Susan had lost track of how long she'd been sitting there waiting for her tracer. Two hours? Three? She gazed out at the deserted Crypto floor and wished her terminal would beep. There was only silence. The late-summer sun had set. Overhead, the automatic fluorescents had kicked on. Susan sensed time was running out. She looked down at her tracer and frowned. â€Å"Come on,† she grumbled. â€Å"You've had plenty of time.† She palmed her mouse and clicked her way into her tracer's status window. â€Å"How long have you been running, anyway?† Susan opened the tracer's status window-a digital clock much like the one on TRANSLTR; it displayed the hours and minutes her tracer had been running. Susan gazed at the monitor expecting to see a readout of hours and minutes. But she saw something else entirely. What she saw stopped the blood in her veins. TRACER ABORTED â€Å"Tracer aborted!† she choked aloud. â€Å"Why?† In a sudden panic, Susan scrolled wildly through the data, searching the programming for any commands that might have told the tracer to abort. But her search went in vain. It appeared her tracer had stopped all by itself. Susan knew this could mean only one thing-her tracer had developed a bug. Susan considered â€Å"bugs† the most maddening asset of computer programming. Because computers followed a scrupulously precise order of operations, the most minuscule programming errors often had crippling effects. Simple syntactical errors-such as a programmer mistakenly inserting a comma instead of a period-could bring entire systems to their knees. Susan had always thought the term â€Å"bug† had an amusing origin: It came from the world's first computer-the Mark 1-a room-size maze of electromechanical circuits built in 1944 in a lab at Harvard University. The computer developed a glitch one day, and no one was able to locate the cause. After hours of searching, a lab assistant finally spotted the problem. It seemed a moth had landed on one of the computer's circuit boards and shorted it out. From that moment on, computer glitches were referred to as bugs. â€Å"I don't have time for this,† Susan cursed. Finding a bug in a program was a process that could take days. Thousands of lines of programming needed to be searched to find a tiny error-it was like inspecting an encyclopedia for a single typo. Susan knew she had only one choice-to send her tracer again. She also knew the tracer was almost guaranteed to hit the same bug and abort all over again. Debugging the tracer would take time, time she and the commander didn't have. But as Susan stared at her tracer, wondering what error she'd made, she realized something didn't make sense. She had used this exact same tracer last month with no problems at all. Why would it develop a glitch all of a sudden? As she puzzled, a comment Strathmore made earlier echoed in her mind. Susan, I tried to send the tracer myself, but the data it returned was nonsensical. Susan heard the words again. The data it returned†¦ She cocked her head. Was it possible? The data it returned? If Strathmore had received data back from the tracer, then it obviously was working. His data was nonsensical, Susan assumed, because he had entered the wrong search strings-but nonetheless, the tracer was working. Susan immediately realized that there was one other possible explanation for why her tracer aborted. Internal programming flaws were not the only reasons programs glitched; sometimes there were external forces-power surges, dust particles on circuit boards, faulty cabling. Because the hardware in Node 3 was so well tuned, she hadn't even considered it. Susan stood and strode quickly across Node 3 to a large bookshelf of technical manuals. She grabbed a spiral binder marked SYS-OP and thumbed through. She found what she was looking for, carried the manual back to her terminal, and typed a few commands. Then she waited while the computer raced through a list of commands executed in the past three hours. She hoped the search would turn up some sort of external interrupt-an abort command generated by a faulty power supply or defective chip. Moments later Susan's terminal beeped. Her pulse quickened. She held her breath and studied the screen. ERROR CODE 22 Susan felt a surge of hope. It was good news. The fact that the inquiry had found an error code meant her tracer was fine. The trace had apparently aborted due to an external anomaly that was unlikely to repeat itself. Error code 22. Susan racked her memory trying to remember what code 22 stood for. Hardware failures were so rare in Node 3 that she couldn't remember the numerical codings. Susan flipped through the SYS-OP manual, scanning the list of error codes. 19: CORRUPT HARD PARTITION 20: DC SPIKE 21: MEDIA FAILURE When she reached number 22, she stopped and stared a long moment. Baffled, she double-checked her monitor. ERROR CODE 22 Susan frowned and returned to the SYS-OP manual. What she saw made no sense. The explanation simply read: 22: MANUAL ABORT

Achieving water neutrality in the Severn Trent region (technical Assignment

Achieving water neutrality in the Severn Trent region (technical report) - Assignment Example The second vital factor is the consideration of the accessibility of water resources both in the future and in the present-day, which can be used to meet the demand for water in areas of Wales and England. Severn Trent serves to bring in water neutrality and efficiency, and it occupies most of the East midland regions. Keeping new developments in mind, the notion of water neutrality serves as a crucial concept. This is so basing the ideologies on water resource management. It can be termed as offsetting the demand for water in a certain community at hand by making existing buildings and homes in the region, to an increasing extent, more water efficient (Environment Agency, 2007). In simpler terms, the up to date house developments should be equivalent to the total demand for water in a certain area. Notably, most studies undertaken on water neutrality have a background related to the definition of the notion. It is imperative to note that the Environment Agency performed a study on the possibility of attaining water neutrality in the Thames Gateway region (Community and Local Government, 2007). This served as a crucial part of the government policy for housing growth which targeted the betterment of the affordability of housing. In order to address this issue, the government’s 2007 Green Paper on Housing was tasked with devising a policy to establish over 3 million new homes by the year 2020. This was to be achieved by working with the rate of 240,000 homes annually. This paper delves to pinpoint that the auxiliary increment in housing would have to be planned for pre-existing Regional Spatial Strategies (RSSs) for recent and existing eco-towns as well as points of growth. The growing trend in housing projects and insubstantial water supplies combined with the threats of variations in climatic conditions, led to the further exploration of

Ethical Considerations on the End of Life Research Paper

Ethical Considerations on the End of Life - Research Paper Example In other cases, the person to be given euthanasia does not have the power to make a decision. This may happen, for example, if he/she is in a state of a comma, or else, he/she is conscious but is fully paralyzed and can do nothing more than fed artificially. According to (Cavan and Dolan 12), euthanasia can be defined as, â€Å"the act or practice of killing or permitting the death of hopelessly sick or injured individuals (such as persons or domestic animals) in a relatively painless way for reasons of mercy.† As this definition indicates, all possible measures are exercised in euthanasia to ensure that it takes the victim minimum pain and labor to die. It is obvious that the victim is given euthanasia by another person.   Issues like euthanasia should be dealt with extreme care and delicacy particularly in the present age when people have grown much conscious about health and safety issues and ethics is considered a priority in every act an individual indulges in. â€Å"All forms of euthanasia, voluntary or involuntary, should be condemned until death is chosen for an individual by law because of his/her criminality.† It is useful to discuss certain types of euthanasia before making an in-depth analysis of the ethical consideration of this dilemma because people tend to argue for or against euthanasia without distinguishing between the various conventional forms of euthanasia. There are two fundamental types of euthanasia depending upon the presence or absence of the will of the person being given euthanasia. These two types of euthanasia are called as the voluntary and non-voluntary euthanasia (Dyck). It may seem surprising that there are people who tend to have euthanasia willingly, though it is true and there may be many reasons for that. Euthanasia which is given after seeking due permission from the victim is termed as the â€Å"assisted euthanasia†.

Analysis of Brutish You Have to Hand it to the Neanderthals after All Research Paper

Analysis of Brutish You Have to Hand it to the Neanderthals after All - Research Paper Example On the contrary, the findings make it more probable that the Neanderthals made the paintings. The article also posits that the wrong dating resulted because scientists dated the paintings using the calcium carbonate layer, which is now believed to have accumulated on the artistic paintings years after the paintings had been made. This paper is an analysis of the article â€Å"Brutish? You have to hand it to the Neanderthals after all† authored by David Keys and featured in The Independent. The paper will also scrutinize additional research related to the articles content as well as dating of Palaeolithic cave painting in Europe. The paper will also try to establish the credibility of Keys' article and application of the research findings. Making use of a process referred to as uranium-series disequilibrium, the group that was led by Pike measured the radioactive decomposition of uranium and dated hand stencils and disks in El Castillo cave in Northern Spain. The paintings had been made by using the mouth to blow paint on the wall. The artistic paintings were found to be least 40,800 years old making them the oldest form of art in Europe. These results have ignited the debate on who is responsible for the cave paintings found in Spain and France. Previously, the paintings were attributed to modern humans but research acknowledges that modern man had not invaded Europe 41,000 years ago. At this period, Neanderthals inhabited Europe, which suggests that they could be responsible for these artistic paintings (Keys, 2012). Chauvet Cave paintings in central France were previously recognized as the world's oldest cave art paintings. The Chauvet cave paintings were dated 39,000 years old. However, the Chauvet cave dating is still controversial since it relies on radiocarbon dating making use of charcoal pigments. Archaeologists have put forward that dating based on charcoal pigments is unreliable since the pigments are susceptible to contamination by other forms of carbon, which would affect dating results. Additionally, using charcoal pigments could be erroneous in that the period when the fire was lit might not coincide with the time the painting was made (Keys, 2012; Pettitt and Pike, 2007). I selected this article due to its relevance to our understanding of the past and  human history particularly the interactions between the Neanderthals and Homo sapiens. Primordial cave paintings lend a hand in connecting the modern man to the past species. Understanding the activities of the Neanderthal is crucial since he was the immediate ancestor of Homo sapiens, the modern man. Understanding Neanderthal would thus enhance a better understanding of the development of the art of painting. Additionally the findings suggest that the Neanderthals could have been the inventors of cave painting but passed the art to Homo sapiens. Evidence shows that modern humans first appeared in Northern Spain about 41,500 years ago, as successors of the Neanderth als. These findings are contrary to current perceptions that the Homo sapiens instigated artistic painting and that Neanderthals did not practice cave painting (Zilh?ao, 2007; Keys, 2012). Another important aspect roused by these findings is that the interaction between Homo sapiens and Neanderthals coul

The representation of Chicanos in films Essay Example | Topics and Well Written Essays - 500 words

The representation of Chicanos in films - Essay Example The depiction of Chicanos as gang bandits is unfair.The Chicanos incorporated the style to invoke change regarding other people’s perception. These messages affirmed traces of change. The article states that stereotyping affects a wide range of ethnicities and not necessarily Chicanos. All ethnic groups have cultures that show that their dirt, vile and uncivilized practices. The article attributes the fishing of compliments in movies as a cause of the negative stereotyping. Amongst Mexican Americans, the expression of self-derogatory occurs through scatological joking (Noriega 185). The reaction towards rebellion emanate through jokes. Individuals found it more comfortable to attack stereotypes against minorities through comedy. Chicanos show resistance against the negative image depiction in US movies through creation of informational lyrics in their films.

In this article, the incorporation of Cholas has a significance of exemplifying remarkable strength and artistic independence that is relevant for survival in a society, especially in the existent of racism that has thwarted a society’s social mobility. The power in cholas is evident in their capability to deal with gangsters, warfare, poverty, and violence. The article affirms in cultural appropriations that the Chola tradition signifies struggle and tough life in gaining identity (Fregoso 322).

How are human diets leading animals to extinction and polluting the Essay

How are human diets leading animals to extinction and polluting the environment - Essay Example Consequently, the environment has not been spared by this trend. Combined with the ever changing nature of human diets across the globe, the enormous demand for animals to meet human diet needs is increasingly leading to the extinction of animal species, alongside causing environmental pollution in the process. The social aspect of the global population is characterized by differentiated lifestyles, all of which account for some given form of diet practices. The coexistence of carnivores, vegans, and vegetarians has given rise to myriad human diets, all of which pressure the environment in one way or another. Demand for animal products is always rising, an aspect that continues to threaten the continuity of animal life. Over and above this, diet management has often being ignored by a significant proportion of the human race all over the world. In this respect, a critical component of human diets relies on animals, land, and most importantly the environment. This observation has trig gered the action and reaction of different people, agencies, and government across the globe. For instance, the sustainable development by Sheikh Zayed earned him the Gold Panda award (Todorova, 2011). A direct observation from this is that human activities, and especially diets, have had critical implications on both animal life and environmental welfare. Therefore, the situation needs to be managed by targeting influential factors such as human diet practices. While human diets continue to result in animal extinction and pollution of environment, it is fundamental to consider all the contributing factors to the observed scenario. Population growth around the world has continued to increase at an alarming rate, especially in less developed and developing countries. The implication of this trend has spread to the diet aspect and demand for food. Increase in the global population directly translates to an increase in the demand for food. The global population, having been comprised o f carnivores, vegans, and vegetarians, obtain its food from differentiated sources. In the process, both red and white meats have become a fundamental component of human diets across the globe (O'Sullivan, 2011). As a result, overfishing, excessive hunting, and killing of animals have been realized. Consequently, the environment has suffered immense pressure, thus lacking adequate time to regenerate for the purpose of sustaining global needs; human diets included. As much as human diets need to be changed and/or managed in favor of animal life and the environment, there is a critical need to manage the global population trend. As changes and shifts continue to be realized in regard to human diets, the issue of genetically modified (GM) food has emerged (Detrie, 2011). GM food continues to receive mixed reactions and actions from different people, agencies, and governments around the world. While some parties argue in favor of GM food, others remain against this kind of food. On the same note, there are some parties that continue to be indifferent about the GM food issue. Although, GM food is increasingly taking strong grounds in some countries, health and environmental concerns continue to pertinent issues that need to be addressed. On the same note, striking a balance between science, morals, and ethics has been a challenge in the implementation of GM food around the world (Malek, 2011). The reluctance and resistance facing GM food has

The Term Enlightenment Essay Example | Topics and Well Written Essays - 1000 words - 1

The Term Enlightenment - Essay Example Spiritual enlightenment is a very thorough process in which a human being’s soul is uplifted towards the divine light and thus brightening his whole personality. Thus it can be said that spiritual enlightenment is the ultimate end of human life and need the deeper awakening of the spirit or the soul. The enlightenment process occurred in the writing â€Å"The library card† is essentially different from that which Plato has described. Plato in his writing is talking about the spiritual enlightenment which leads to salvation. It is about a divine awakening in a person which changes his perception and view of the whole world and himself. When the idea of a human being change due to the enhancement of his knowledge cannot be completely categorized as spiritual enlightenment rather it is just a revolution in his thoughts and outlook about him and the world.The author of the essay explains the way in which he had an opportunity to experience the sense of awakening with the he lp of different books and novel.He is a black man had very little knowledge about the real living style and thoughts of white men.
