Example research essay topic: A Kiss That Embodies Love 468 words Essay A Kiss That Embodies Love Gustav Klimts The Kiss has been close to my heart for the past seven years. To me this artwork represents an embodiment of true love because the image represents what I consider to be traditional romantic love. The male figure appears protective of the woman, yet he also seems nurturing. The female figure has the soft femininity of a traditional woman, yet she appears to be an equal contributor to the relationship as well as to the painting; neither the man nor the woman predominates. The Kiss conveys this to me through the color and shape detail, the embrace of the lovers, and its romantic theme. The colors used in the image are not the traditional colors of love. Reds, purples, and pinks are replaced with an abundance of golds, browns, and greens. Many reproductions of The Kiss are colored with a glimmery shine that captures and demands the attention of the viewer. The rich fall colors represent a harmony between the extremes of summer and winter, as the painting is a balance between the extremes of lust and hatred: true love. The shapes Klimt chose to define the man and woman is squares and circles. There is no distinction of where the their bodies end and begin except where the squares and circles meet. The squares represent the masculinity of man with rigid and exact form. Circles, in contrast, have the femininity of a woman.

The circles are also opposite of the squares in relation to the faade of colors. Klimt filled the squares with dominating blacks, whites, and browns. The circles he filled with a more colorful array of greens, golds, and reds. The embrace and kiss between the lovers is gentle and enchanting. However, there is a hint of abstractness in the way the heads are bent to the side in an unnatural fashion. The mans face is not as available as the womans. What the viewer sees of the mans face is only a defined jawline, nose, and brow in profile. The womans face is a full frontal view capturing all of her features. The man is cupping the womans face in his bulky hands as one of her frail hands touches one of his assuring that he remains holding her. After researching Klimt, I discovered that the painting was a portrait of himself and Danae, his true love. This discovery reinforced my idea that The Kiss represents a true love; whether the love represents a pure romantic love or not remains unknown. In any case, Klimts most well known masterpiece is a mystical, alluring, and intriguing piece. The Kiss leaves the viewer open to relate his or her own personal view of intimacy. Bibliography:.

Using Cell Phones in School

Using Cell Phones in School With Americans checking their phones 8 billion times a day (thanks for that stat, Time.com), most of us can agree that we dont leave home without them. Thats also true for students. Only a few short years ago, many schools banned cell phones, but many schools, especially private schools, have changed their rules and now allow smartphones and tablets to be a part of daily school life. In fact, some schools now have 1-to-1 device programs, that requires students to use laptops, tablets or even phones as part of their daily work. Most schools still have rules about using cell phones, in that ringers must be turned off and phones must be put away at certain times, such as during tests or presentations. But some teachers are capitalizing on students constant need to be connected. From text reminders and notifications to school apps for turning in homework and checking into dorms, our devices are enhancing the learning experience.   Using Cell Phones in Schools is Mainstream   In private schools, the prevailing view is that cell phones are here to stay. They are not only an essential line of communication between frantically busy parents and their children but are also a tool that many educators and coaches rely on to keep students engaged. As a result, most private schools allow cell phones on their premises with the understanding that students must adhere to  specific guidelines written into their handbooks and acceptable use policy manuals. All students agree to abide by those rules both while on the school premises and also while under the schools jurisdiction when off campus. Learning Opportunities Believe it or not, smartphones and tablets are more than just social communication hubs. Some schools have even worked mobile devices into the daily curriculum, allowing students to use their phones for school work during class. With the growing number of educational apps, its no wonder that these devices are becoming a valuable part of the educational environment. Students today are using apps in robotics, presenting directly from their phones and sharing documents with teachers on the fly thanks to the implementation of mobile devices in school. There are many apps to choose from, ranging from polling and testing apps to language-learning apps and math games.  Socrative  is an app that allows for real-time polling in class, while some schools are using  Duolingo  as a summer learning opportunity to help students prepare to take on a second language. Many games incorporate critical thinking and problem-solving skills, as well as physics to solve problems and maneuver through game levels. Some schools are even offering classes that educate students on how to build their own apps, teaching them the skills they need to thrive in our digital world. Boarding Schools and Cell Phones Every student has a cell phone at home these days, and there is no exception when home is a boarding school. In fact, many boarding schools capitalize on the fact that their students are chained to their mobile devices, using them to communicate and keep track of students. Many boarding schools use apps that allow students to check in and out as they come and go from different buildings and activities, and leave campus. These apps often feed a dashboard accessible by teachers, administrators and dorm parents, helping the adults on campus ensure the safety and well-being of students.   Cell Phones Provide Connections with Parents   Any parent will tell you that their worst nightmare is not knowing where their child is. A thousand gut-wrenching scenarios run through their mind: Is my child ok? Has he or she been kidnapped? In an accident? Its much worse for a big city parent. The variables increase exponentially to the point where you become a nervous wreck. Subways, buses, the weather, purse snatching, hanging around the wrong friends - supply your own worries about your children. Thats why cell phones and other smart devices are such wonderful tools. They allow for instant communication with your child by voice or text message. Cell phones can turn an emergency into a relatively easily handled and controlled event. They can give instant peace of mind. Of course, we are assuming that your child is honest and is where he says he is when you call. For boarding school students, the cell phone helps students stay connected with their families who are miles away. Gone are the days of waiting by the payphone for calls in the common area or obtaining a landline in the dorm room. Parents can now Facetime and text with students at all hours of the day (just not during the academic day!).   The Opposing View There is still evidence of cell phones being a distraction in school if not properly managed. Small size and inaudible, high-pitched ringtones make cell phones easy to hide and use in situations that dont warrant them. It is a proven fact that adults over 30 cannot hear some of the high-pitched ringtones that teens use deliberately for that reason. Cell phones can be used to cheat, to call the wrong people and to bully classmates, especially over social media. For these reasons, some teachers and administrators want cell phones banned from school, however, studies have also shown that educating students on proper usage and providing strict guidelines with consequences for infractions will actually benefit students and prepare them for life after high school. The sensible approach is to create a set of rules and policies regarding cell phone use, educate students on best practices and ethical use, and enforce the rules that are put in place.

Natural Slope Stability Assignment Example | Topics and Well Written Essays - 5000 words

Natural Slope Stability - Assignment Example Softening of slope cause many hills and mountain to have a landslide causing damage to infrastructure and injury to some. In UK an increasing number of landslides has been occurring because of the late study of the stability of the slope. A case study will be presented to show the evaluation of the slope geotechnically. The study considers the causes of landslides and what measures could be taken to manage the risks of these occurring and is reported elsewhere. This study also show things to consider in the effect of that climate change might have on the design and operation of roads, to identify whether any changes in current practices are required. The focus of this study is the influence of rainfall in the stability of the natural slope.This study includes in how to predict the possible continuous rainfall to avoid landslides in many areas in UK. This paper shows the study in geotechnical way. Possible solution on many landslides are given to prevent loss of life and possible damage to properties. The case study presented in this paper was done by the Scottish engineers, to predict possible slope instability that causes landslide because of continuous rainfall. The study location is in the road network of Scotland In August 2004 a series of landslides in the form of debris flows occurred in Scotland. Some of these affected the A83, A9 and A85, which form part of the trunk road network. These incidents were well reported in the media. While debris flows occur with some frequency in Scotland, they only rarely affect the trunk road network or for that matter the main local road network. However, when they do impact on the road network the degree of damage, in terms of the infrastructure and the loss of utility to road users, can have a major detrimental effect on both economic and social aspects of the use of the asset. Additionally, there is a high potential for such events to cause serious injury and even loss of life although, fortuitously, such consequences have been limited to date. The events of August 2004 followed a sustained period of heavy rainfall and, in addition, intense localised storms contributed to the triggering of at least some of the resulting debris flows. Rainfall of up to 300% of the monthly average fell in certain parts of Scotland during August 2004. Within the recent past, debris flow activity in Scotland has occurred largely in the periods July to August and November to January, but there is no certainty that such a pattern will be continued in the future. However, eastern parts of Scotland do receive their highest levels of rainfall in August. Additionally, climate change models indicate that rainfall levels will increase in the winter but decrease during the summer months but that intense storm events will increase in number. These factors, therefore, may change both the frequency and the annual pattern of debris flow events. The impacts of such events are particularly serious during the summer months due to the major contribution that tourism makes to Scotland's economy. Nevertheless, the impacts of debris flow events during the winter months should not be underestimated. Evaluation of the Study What is a Natural Slope Slope as defined in Encarta is the maximum angle at which soil can be banked without slipping. The slope can be natural (natural cliffs and hillside) or artificial or constructed (cuttings, embankments, quarries, spoil tips

Archetypes - Essay Example She mixes up her business professionalism with life care, in that she endows the main task of caring for the child. This movie lays credence to the socio-economic position of the global period during that 10-year period, characterized by the decreased growth of countries’ low standards of living. Her final decision that overcame the thought of an adoption, as she had grown attached to the child shows how the female figure appreciates life. The viewers remain appreciating the rational decision presented. They remain criticizing her male counterpart who abandoned her at her most crucial time (Harold Ramis), an investment banker. Despite all the challenges and hurdles that Wiatt had grown through including suffering a nervous breakdown, she later resurfaces, and all hopes are high when her Baby Food company sales at millions. With the improvement in the world economy, women leadership position has even been more solidified as the new economic period ushers occurs. The movie, The Devil wears Prada of 2006; shows career based female power, love, and friendship linkages in complex and sometimes paradoxical perspectives. Women power linkages explained in the movie reveal that females utilize power effectively to ensure they are competitive in business. They also help other women advance in their careers. This is evident when Andrea acts loyal to Miranda when she attempted to warn her against the coup that intended to overthrow Miranda for a younger woman. However, love and friendship linkages deteriorate, as women become successful professionals. In spite of linkage drawbacks, such movies portray optimism and stable women figure images for young females in the workforce (Danya 70). With the high and improved economic standards, there has been enhancement in life and consequently because of westernization, social evils such as prostitution and production of pornographic materials have sprung up. In the 2004 American teen film, The

Health Policy Analysis Assignment Example | Topics and Well Written Essays - 3750 words

Health Policy Analysis - Assignment Example Patient navigators and navigator programs therefore became necessary in terms of providing the much needed connection between patient populations and providers with an aim of improving healthcare outcomes. Patient navigator and outreach services dates back to the year 1971 when then US President Richard Nixon ratified the National Cancer Act. Since then there have been significant improvements in healthcare outcomes in terms of reducing cancer related mortality. This can be attributed to better measures at preventing, screening and diagnosing cancer as well as the use of better treatments for the same. However, poor persons, those without any medical insurance and those without sufficient insurances covers have continued to show low 5-year survival and high rates of mortality. Disconnects still exist between discovery and delivery enterprises and also between what is known and what is applied to all people. Disparities arise when medical interventions meant for all are not equally distributed. Disparities are also occasioned by a combination of economic, cultural and social issues (Freeman and Rodriguez, 2011). Poverty is a very important cause of healthcare disparities when it comes to the management of cancer and other chronic illnesses. Poverty is a complex problem associated with other issues such as lower levels of educational achievement, squalid living conditions, total lack or insufficient social assistance, lack of employment, risky lifestyles and reduced healthcare service access. As per the 2010 national census, 14.3% of the US population representing a whooping 43.6 million persons was poor the year 2009 alone. In the same year 16.7% (50.7 million) of American citizens did not have any health insurance cover. Furthermore statistics have shown a huge gap in terms of the five year survival rates for cancers between the poor and the rich; survival is ten percent lower among the poor Americans compared to the rich. An emerging

The Crude Oil Distillation Engineering Essay

The Crude Oil Distillation Engineering Essay Basically, the product produced in this process can be categoried into 4 group, they are: light distillates, middle distillates, heavy distillates and others. The example of light distillates are liquid petroleum gas (LPG), gasoline, and kerosene. Apart from that, the products that can be classified as middle distillates are residential heating fuel and aautomoblie diesel fuels. Additionally, bunker fuel oils is an example of heavy distillataes, while petroleum cokes, lubricating oils and carban black are the other products in this distillation process. The brief description of crude oil distillation unit (CDU) process is as follow. First of all, the incoming crude oils is heating up before it is entering the fractionation column by heat exchanger. After that, the crude oil will pass through an equipment, called desalter, to remove water droplets and inorganic salts that contained in crude oil. Then, it will be further heating by heat exchanger. Next, crude oil will enter a furnace. At here, it will be heating up to 330-350 Â °C. The crude oil then is flashed in the atmospheric distillation column. At here, it is separated into a number of fraction with a particular boiling range. When each fraction in the distillation column reaches a tray where the temperature is just below its own boiling point, crude oil will be condensed and changes back into liquid phase. Moreover, heaviest fractions will condense on the lower trays and lighter fractions will condense on the higher trays in the column. At different elevations in the column, the fractions actually can be drawn out on gravity through pipes, for further processing in the refinery process by using a special trays called draw-off trays. The fraction is drawn out from the top, side and bottom of the distillation column. These fraction is the products that produced in this distallation process. Vacuum Distillation Unit (VDU) For vacuum distillation unit (VDU), its main purpose is to separate the heavier end products such as vacuum gas oil and slop wax that is from the atmospheric distillation unit. The brief description of the process is as follow. First of all, heavy crude oil is heated by a series of heat exchanger and crude furnace to the desired temperature, which is 350-390 Â °C. After that, the crude oils flashed into the vacuum distillation column to separate the heavy crude oil. The separation is same as the separation in CDU process; light vapors rise to the top and heavier hydrocarbon liquids fall to the bottom. Next, crude steam is injected into the base of the distillation column to enhance the division of lighter boiling components from the bottom liquid. Then, Light vapour gases are abtracted at the top of the distillation column, it is condensed and recycled back to the column as reflux. For light naphtha, it is drawn off and excess gases are sent to flare. However, vacuum gas oil (VGO) and lubricating oils are drawn off and routed for further treatment in hydrotreating units. Apart from that, vacuum residue from the bottom of the distillation column is sent to intermediate storage or typically to be further processed in fluidic catalytic cracking (FCC) process or delayed coking unit. Fluid Catalytic Cracking Fluid catalytic cracking is the primary conversion process in petroleum refinery. It is the unit which utilizes a micro-spherodial catalyst (zeolitic catalyst) which fluidizes when properly aerated. The purpose of this process is to convert high-boiling petroleum fractions (gas oil) to high-value, high-octane gasoline and heating oil. This process uses the instrument called Circulating Fluidized Bed. This Circulating Fluidized Bed has fast fluidization regime and also good for catalyst is the size of less than 0.2 mm. They are also excellent in Gas-solid effective contact, Catalyst effectiveness, Catalyst internal temperature control, and Catalyst regeneration. The operating characteristics of this instrument are; Particle Diameter = 150 mm Geldart Classification = A Temperature = 650 0C Pressure = 100 kPa Superficial gas velocity = 10 m/s Bed depth = 0.85 m Fresh feed flow rate = 300,000 kg/hr Catalyst to oil ratio = 4.8 There are 6 steps of processes that occur in FCC. Reactor, Riser, Cyclones, Stripper, Regenerator, Standpipe and Slide Valve. Firstly, the reactor performance, the feed oil enters the riser near the base and contacts the incoming regenerated catalyst. Then the cracking reactions occur in the vapor phase. The expanded volume of vapors lifts the catalyst and vaporized oil rises. This reaction occurs at a very high speed, usually about few seconds of contact time. Secondly, the riser, which has diameter of 1.2 meters and height of 36.6 meters, has a plug flow with minimum back-mixing. Steam is used to atomize the feed, this increases the availability of the feed. The outlet vapor velocity would reach up to 18 ms -1. The hydrocarbon residence time is 2 seconds. Followed by, Cyclones. It is located at the end of riser to separate the bulk of the catalyst from the vapor. It uses a deflector device to turn catalyst direction downward. It will later undergo two stage cyclones in order to separate the remaining of the catalyst. It then returns the catalyst to the stripper through the diplegs. The product vapors exit the cyclones and flow to the main fractionator column. Then, the spent catalysts fall into the stripper. The valuable hydrocarbons are absorbed within the catalyst bed. Stripping steam, at a rate of 4 kg per 1000 kg of circulating catalyst, is used to strip the hydrocarbons from the catalyst. The catalyst level provides the pressure head which allows the catalyst to flow into the regenerator. The regenerator basically has two functions, one, restores catalyst activity. Two, it supplies heat to crack the feed. Air is the source of oxygen for the combustion of coke. The air blower with 1 m/s (3 ft/s) air velocity to maintain the catalyst bed in a fluidized state. About 14 kPa (2 psi) pressure drops in air distributors to ensure positive air flow through all nozzles. In standpipe and slide valve, it provides the necessary pressure head needed to circulate the catalyst around the unit. The catalyst density in standpipe is 642 kg/m3 (40 lbs/ft3). Slide valve is used to regulate the flow rate of the regenerated catalyst to the riser. Slide valve function is to supply enough catalyst to heat the feed and achieve the desired reactor temperature. Hydrocracking process Crude oil undergoes hydrocracking process after undergoing vacuum distillation and coking processes. Hydrocracking process is a catalytic chemical process used in petroleum refineries for converting the high-boiling constituent hydrocarbons in petroleum crude oils to more valuable lower-boiling products such as gasoline, kerosene, jet fuel and diesel oil. The process takes place in a hydrogen-rich atmosphere at elevated temperatures (260 425 Â °C) and pressures (35 200 bar). This process removes feed contaminants such as nitrogen, sulfur, metals. Hydrogenation occurs in fixed hydrotreating catalyst beds to improve hydrogen/carbon ratios. The size of the molecules must decrease and the atomic H/C ratio must increase if the products are to become useable as conventional fuel products. This is followed by one or more reactors with fixed hydrocracking catalyst beds to dealkylate aromatic rings, open naphthene rings, and hydrocrack paraffin chains. Major products from hydrocracking are jet fuel and diesel, while also high octane rating gasoline fractions is produced. All these products have a very low content of sulfur and other contaminants. Hydrocracking is normally facilitated by a bifunctional catalyst that is capable of rearranging and breaking hydrocarbon chains as well as adding hydrogen to aromatics and olefins to produce naphthenes and alkanes. This process cracks the high-boiling, high molecular weight hydrocarbons into lower-boiling, lower molecular weight olefinic and aromatic hydrocarbons and then hydrogenates them. Any sulfur and nitrogen present in the hydrocracking feedstock are, to a large extent, also hydrogenated and form gaseous hydrogen sulfide (H2S) and ammonia (NH3) which are subsequently removed. The result is that the hydrocracking products are essentially free of sulfur and nitrogen impurities and consist mostly of paraffinic hydrocarbons. Basically, hydrocracking process consist of the splitting or breaking of straight or cyclic hydroca rbons and hydrogenation of the broken bonds. Example: For futher details about the yield and disposition, refer to the table below: Product Yield, volume% feed Disposition Light ends Varies depending upon objectives LPG Naphtha Gasoline, catalytic reformer Diesel Diesel Total volume yield 130 140 Gas oil conversion 60 99% They are two stages of hydrocracking unit; Single Stage Process and Multi Stage Hydrocracker. It is called a single stage process when the treating step is combined with the cracking reaction to occur in one reactor. The catalyst used in a single-stage process comprises a hydrogenation function in combination with a strong cracking function. In the case of high/full conversion is required, it becomes necessary to switch to a multi-stage process, in which the cracking reaction mainly takes place in an added reactor. Two versions of the multi stage hydrocracker have been developed; two stage hydrocracker and series flow hydrocracker. Both two stage and series flow hydrocracking are flexible process. The two stage process is more selective because product made in the first reactor is removed from the second reactor feed. In series flow operation, this product is partly overcracked into lighter products in the second reactor. Schematic of a two-stages hydrocraking unit HYDROTREATING PROCESS (Prepared by DING TIONG SOON, 10UEB01031) Hydrotreating technology is used in refinery processes to remove contaminants such as sulfur, nitrogen, condensed ring aromatics, or metals to produce a clean product for further processing. Hydrotreating process includes Naphtha Hydrotreating, Gasoline Hydrotreating, Mid-Distillate Hydrotreating and FCC Feed Pretreating. The feeds used in this process range from vacuum resid to naphtha , and the products are used as environmentally acceptable clean fuels. In the hydrotreating process oil fractions are reacted with hydrogen in the presence of a catalyst to produce high-value clean products. The operating conditions will depend on the final application. The heart of hydrotreating process is the reactor section, which features a high-pressure reactor vessel and proprietary catalyst and reactor internals technology. Hydrotreating process began when the liquid feed stream is joined by a stream of hydrogen-rich recycle gas. The mixture is then preheated by flowing through a heat exchanger. After that, it is heated to the desired hydrotreating temperature using a fired heater where the feed mixture is totally vaporized. Hydrotreating takes place when the feed mixture flows through a fixed-bed reactor in the presence of a catalyst consisting of an alumina base impregnated with cobalt and molybdenum.The hot reaction products are cooled by flowing through a water-cooled heat exchanger before it flows through the pressure controller (PC) and undergoes a pressure reduction down to about 3 to 5 atmospheres. The resulting mixture of liquid and gas enters the high pressure separator which separates the liquid hydrocarbon from the hydrogen , hydrogen sulfide or ammonia gas. Most of the hydrogen-rich gas from the gas separator vessel is recycled by routing through an amine contractor for the removal of acid gas and is reuse in the reactor section. Any excess gas from the gas separator vessel joins sour gas from the stripping of the reaction product liquid. The liquid from the gas separator vessel is routed through a reboiled or steamed stripper distillation tower. The stripper only have two products ,a top and a bottom. With a steam stripper, downstream processing, typically a salt dryer which is preceded by a vacuum dryer, is required to remove water from treated products. If multiple products are produced, then a fractionator with a fired reboiler is also used. Further separation of LPG gases occurs in the low pressure separator prior to sending the hydrocarbon liquids to fractionation. Meanwhile, the sour gas is sent to the refinerys central gas processing plant for removal of the hydrogen sulfide in the refinerys main amine gas treating unit and through a series of distillation towers. The Importance of hydrotreating is that it helps to improve air quality by desulfurization of fuel oils. Hydrotreating prepares valueable hydrocarbon products from heavy carbon streams and the production of low-sulfer-level fuel oil from residual stocks after distillation of crude oil. Coking (prepared by Soo Voo Yee, 10UEB01889) Coking is a thermal process for the conversion of low value residue to valuable products and coker gas oil. There have two types of coking process, which are delayed coking and fluid coking. For the delayed coking process, at first, the residual oil from the vacuum distillation unit is pumped into the bottom of the main fractionators. Along the way it is pumped to the furnace, some steams are injected to heat it to its thermal cracking temperature of about 4800C. The injected steam helps to minimize the deposition of coke within the furnace tubes. Besides that velocity inside the tube of the furnace is very fast. This is to reduce the loss of heat as a waste of source. Because of the short period in the furnace, so the coking of the feed is delayed until it reaches the large coking drum. Compared to the furnace, drum provides a longer period for the cracking process to proceed to completion. For the gas oil and the lighter components will leave from the top of the drum, left behind the components of liquids and solids. The gasses will be directed to the main fractionators to separate it into gases, naphtha and light and heavy gas oils based on each boiling points.The solid coke is deposited and remains in the coke drum in a porous structure that allows flow through the pores. 16 to 24 hours are needed to fill the drum full as a complete coke drum cycle. The hot mixture is switched to another empty drum, when the first drum is full of the solidified coke. While the second drum is filling, the full drum is steamed out to reduce the hydrocarbon content of the petroleum coke, and then is cooled down with water. The top and bottom heads of the full coke drum are removed, and the solid petroleum coke is removed from the coke drum via hydro jetting. The pressure of the water is about 1250psig to 4000 psig and the flow rate is about 750GPM to 1250 GPM. Fluid coking is a continuous process which consists of 2 units, reactor and furnace. In the reactor, the coke particles are fluidized by steam. The preheated feed will be injected directly into the reactor when it reached temperature of 2500C to 3500C. The temperature inside of the reactor is around 4800C to 5700C. On the surface of the coke particles, cracking process is occurred, causing the lighter components are being vaporized. To separate the entrained coke particles with the vapors, cyclones are used. The vapor is then sent to the bottom of the scrubber and condensed into heavy tar; meanwhile the remaining coke is removed and recycled back to the coke reactor. The overhead of the vapor is directed to a fractionator where it is separated into the desired boiling point fractions. Then the coke particles flow to the stripping zone to remove any product vapor between the coke particles. After that, the coke particles are sent to the burner. A part of the coke is burned to remain the average bed temperature. Hot coke is then sent back to the reactor. To maintain the coke inventory in the burner, coke which is one of the products, required to withdraw from the burner. The large coke particulate will be replaced by the smaller seed particles to prevent the circulating coke is too coarse. Compare to delayed coking process, fluid coking will be carried out at a more uniform and higher temperature and shorter contact time. The products produced by using fluid coking process are more valuable and less coke.

Gentoo Install Guide :: essays research papers

Gentoo Gentoo-http://www.gentoo.org/ Gentoo is a distribution that has 3 different install methods. You can just install from the CDs known as stage 3. You can install the base system from CD known as stage 2 and then custom compile the rest of the OS from scratch to bring it to stage 3. This makes the system faster and more responsive but takes some time. Last is the stage 1 install where EVERYTHING is built from scratch. This makes for an EXTREMELY customized and streamlined system. However this method can take DAYS depending on the speed of your computer. A broadband connection would be recommened for a stage 2 or 1 install. Gentoo does all this with what is called Portage. you can basically type "emerge nameofprogram" and it will download, configure and compile the software for you. This makes maintaining the system very easy. Gentoo also has a great support base and is available for the MAC platform as well. install guide Note-The following guide is EXACTLY what I did for my install and it was adapted from the official gentoo installation handbook here.-http://www.gentoo.org/doc/en/handbook/index.xml 1. Download and burn the x86 minimal ISO and boot from the CD. 2. You will see a boot prompt where you can choose different kernels or view other options. We'll just hit enter since we don't need anything special. 3. You will then see a splash screen with a purple cow and the system will boot in the background. 4. When it's done you will have the standard linux command prompt. You will do everything for the install from here. No GUIs for you . 5. For this guide I will use an internet connection for everything. It is possible to install from CDs as well but including that info here would make it WAY too long. As such we need to maek sure networking is working correctly. To check use the "ifconfig" command. There should be an entry for eth0. If so run this command "dhcpcd eth0" that will request an ip address from the router. If you don't see anything with ifconfig try "ifconfig -a" if there is no ethx entry then the network card did get the correct driver loaded at boot. You will have to look up what kind of network card you have and find the appropriate module (driver) and load it using the modprobe command. I had to do this myself "modprobe pcnet32" to load the correct driver.
