Kathy Kudler opened Kudler Fine Foods in June 1998, and grew quickly to open the 3 locations in as little as 5 years. While the mission is to provide the finest products and to assure Kudler is the purveyor of choice for customers aspiring to purchase the finest epicurean delights, the company must have the best possible technology to meet the business needs.The objective is critiquing possible Servers that will improve the protection of data, provide a stable environment to support business, allow transaction monitoring, store sales transactions from POS terminals, backup data, and manage databases. The purpose is to weigh the pros and cons of the different servers, find the one server that will meet the needs of the business, and imple ment the server to the end users. The critique will include security, administration, networking, performance, and programmability.Security When beginning a discussion of computer security, a number of variables come into play. From patch availability to OS popularity, antivirus offerings, user/administrator knowledge and even physical user controls, many elements must be considered to create a computing environment that is secure. While Windows and Linux each have their advantages and disadvantages, neither operating system is, at its core, more or less safe than the other from attacks and data theft.All operating systems have vulnerabilities before they ever ship, and it is up to the administrator of those systems to maintain a level of security that protects the valuable data stored on those servers. Windows and Linux operating systems have a few large advantages and disadvantages that are worth analyzing when considering security. Interestingly enough, the largest advantage is p robably also the largest disadvantage. Windows is the most widely used operating system in the world, so there is a large user community and thousands of employees at Microsoft that work to improve security daily.By the same token, it is also the operating system that is most widely targeted by virus and malware programs that individuals create either to profit or just create general mayhem. Since the Linux user base is much smaller, it is less advantageous for individuals to create viruses and malware for Linux systems, since the impact would be much smaller. Additionally, Linux is a less familiar and more difficult operating system to install and maintain, so the user base for Linux is widely more knowledgeable than that of Windows operating systems.This was exacerbated in previous versions of the Windows OS because user access control was much looser than it is currently. Since the inception of Unix and later Linux, the operating system was predicated on the idea that users shoul d have as limited access directly to the system kernel as possible. (Is Linux Really More Secure Than Windows? , 2011). Another item that is frequently referenced when comparing Windows and Linux security is the configuration of, well, everything. Windows takes the approach of doing as much as is efficient for the user, rather than the user having to do it themselves.Linux forces users to take much more control of any software they install or connections they set up, which adds flexibility but gives birth to a wide array of human error possibilities. There are pros and cons to both of these philosophies, because the Windows approach means the software is probably more secure out of the box, but the Linux software gives users the ability to enhance security in greater detail without having to wait on someone else to develop a security patch. AdministrationThe duty of the administrator is to solve problems that arise when workstations go down and maintain the system to run consistentl y without errors or interruptions. According to Gite the duties of the system administrator are a wide-ranging and vary widely from one organization to another. The administrators not only put out fires but also manage user accounts, password resets, software patches, backup creation, and other various system maintenance tasks (Venezia,  2011). The decision to use any particular server over the other will be based on the business needs.Kudler Foods will need to employ at least one IT employee, and this employee‘s skills will need to be with either the Windows server, or the various flavors of UNIX or Linux. Automating tasks is much easier to do using UNIX and Linux than with the Windows server. UNIX and Linux are both more economical in terms of licensing than the Windows server. Windows servers are able to run batch scripts but are very limited without the available commands that are found in UNIX. Administrators will need to reboot the system only a few times a year while using UNIX or Linux, but will need to reboot the Windows system weekly.All servers have support available, if users are not familiar with servers, then it isn’t necessarily any more difficult to learn one server over another (Jensen, 2007). The recommendation for administration on which server to use for the business depends on the needs of the business and what experience the administrator has with servers. It is recommended in any case that outside tech support is obtained for support that may arise that cannot be maintained by the administrator. Networking Choosing Windows server over Linux has several up and downsides to it. Linux is a freeware, and said to be about 25% faster than windows.Also, the open source software allows for endless possibilities for the IT team. One of the downsides is that a higher level of expertise is needed to keep the environment going. Also, kernel modifications are needed in order to make changes to how things operate. Kernel changes need to be performed perfectly or damage could be done to the entire OS leaving all data inaccessible. Windows may come with license fees but the operating system is pretty fail safe to use, and hard to break. Applications are easier to implement on windows than Linux, as most applications are created for windows use.Access controls are far superior in Windows as well letting the user set access control without having to use software add-ons. Patches are used in both systems however windows patches are all packaged through Microsoft and downloaded with updates, whereas Linux patches are available through open sources as well as commercial providers such as Red Hat (when available). Searching for applications to use with windows are easily found and downloaded. Searching for packages on Linux is much harder and they are sometimes not found (which means having to create them or use a modified version that needs tweaking).Windows server supports standard features such as: The ability to bind multiple network adapters with different media types; this is a great feature to have when using multiple network adaptors, and need them to be used in a certain order. Physical and logical multi-homing; Granting multiple IP addresses access can be a pain, because some may be static and some assigned by DHCP. Sometimes both are not accepted to allow access at the same time. Duplicate IP address detection; Duplicate IP addresses can cause problems locking up one user, and letting the other user have access to areas they should not have access to.Detecting these addresses saves hours of troubleshooting time. Dead gateway detection; Having gateways open and not being used is a security risk that will let outside users gain access to servers. Automatic Path Maximum Transmission Unit discovery; Having to find and set the pathway for certain programs can be a pain using Linux. Having it done automatically can save large amounts of time with multiple programs. Performance enhancements are included such as: Protocol stack tuning; Default window sizes are increased, and new algorithms for high delay and high loss links are included.Round Trip Times as well as timeouts are improved. Number of connections management is improved, and has higher performance. TCP fast recovery and fast re-transmit helping to overcome errors. Windows server has an overall simplistic layout that is a failsafe OS to use. For a smaller company that needs a server for basic use, windows server is the way to go. Using a Linux server will require more expert knowledge to setup and use costing the company the salary of a highly paid employee to manage the server. Basic IT employees can use a windows server to its max, and receive higher levels of tech support if needed.Windows may come with a cost, but it is a fast install that will be ready to go, and use right away. Performance The choice of integrating either a Unix server or a Windows server can be a decision that all comes down to performance. As for Kudler Fine Foods, it will be a decision that will shape the success of a company. There are multiple areas to focus on when looking at system performance. One must take into account system uptime, security impact on performance, hosts accessing the server, database application integration, ability to customize, etc.The different impacts on performance and company expectations help dictate which server to implement into the working environment. The Unix server is vulnerable and has drawbacks just as the Windows server. However, the flaws for the Unix server are less impacting on a company such as Kudler Fine Foods. The Unix server does not provide as many resources for end user support and would require trained and knowledgeable staff that knows the Unix server to operate the system. All features of a Unix server are accessed through the command line and some features are accessed through the Graphical User Interface.The Unix server requires re-boots on a rare occasion such as when system updates occur, application implementation, and application failure. The uptime for a Unix server is generally higher than a windows server. The windows server has more frequent system updates. Updates are common occurrences for the Windows server compared to the Unix server, thus requiring more re-boots for implementation. The server does have an abundant amount of support through Windows, forums, and other organizations.The Windows system does require more re-boots to clear the system out, allow for updates, and address critical software failure. However a system reset every once in a while is not grounds for a final deciding factor on which operating system to implement. Programmability Windows and Linux both come in different â€Å"flavors. † Windows is exclusive to Microsoft but the different versions of Linux come from various companies, including Red Hat, Ubuntu, Xandros, and Knoppix (Tackett amp; Gunter, 1997). Both operating systems have a desktop and s erver version. Both rograms have a GUI and a command line interface. Linux uses fewer resources than Windows and does not suffer from the infamous â€Å"Blue screen of death† faced by many Windows users. Linux is a UNIX based open source operating system designed by programmers scattered around the world. It is capable of operating on a variety of computer platforms (Hart, 2010). Because Linux is an open source program, anyone can access the code to modify or enhance its capabilities to perform a multitude of tasks. The disadvantage to having an open source code is the potential danger of someone deleting vital data.Since Microsoft is proprietary software, this capability is not available in Microsoft’s operating system, reducing the threat to its source code. The original version of the Windows OS was announced in 1982 and shipped in 1985. The Windows NT based OS has been in use since 1993 (Microsoft, 2011). Current versions support direct and sequential access to fil es systems, multiple processors, long descriptive name, task to task communications and synchronization, with increased protection against unauthorized and accidental access or corruption to its files.Several versions support the Windows Application Processing Interface (API) (Hart, 2010). Windows has evolved over the years to a more efficient application with improved graphical capabilities. Current versions of Windows run on a variety of media which include cell phones, handheld devices, laptop PCs and enterprise servers. Both Windows and Linux offer a trial version of their OS but because of its smaller file size, Linux can be run from a CD or flash drive, a feature which Windows can no longer provide.As a supplier of upscale gourmet foods, Kudler’s website uses a variety of graphical designs. The Windows server is a better solution for this company because of its graphical capabilities. Despite Kudler’s consistent growth, the company is committed to keeping its exp enses down and its profit margin up. Linux may seem like a programmer’s dream come true, but the extra expense of hiring a programmer to maintain a Linux environment would be detrimental to the company at this time. Unlike Microsoft’s OS, Linux does not provide an 800 number for support.The company must weigh the benefits of a free open source operating system against the benefits of a paid but supported operating system. Conclusion/ Recommendation Since Linux and Windows both have their individual advantages and drawbacks, a blended solution would meet the needs of the business best. By combining the two operating systems and using them in tandem, Kudler will be able to draw on the strengths of both operating systems to overcome the drawbacks of each. References Jensen, J.

The Canadian Economy & the Global Economic Crisis Essay

The Canadian Economy & the Global Economic Crisis - Essay Example The researcher states that the global economy is presently in crisis reminiscent of the Great Depression of 1929. The global economic crisis began with a US credit crunch and mortgage crisis and has had ramifications throughout the modern, capitalist developed world. The researcher of this essay aims to analyze how has the Canadian economy handled the global economic storm during this period of near universal economic contraction and what can the world learn from the Canadian economic model and how has it been successful. Seeking to explain these question and others which deal with the first global economic crisis of the twenty-first century, this research paper explains and evaluates Canada’s policies in light of global economic meltdown. Calling Canada a â€Å"role model† for other countries around the world, the World Economic Forum called Canada's banks the worlds’ â€Å"soundest†. Presently, the Canadian dollar is around $.97 USD, which is historicall y high and is thought of by many as an indication that the Canadian economy is doing well. Strong macroeconomic policies have ensured that the Canadian economy remains vibrant today. Asking whether or not this is the case, the following will explore Canada's response to the global economic financial crisis. The researcher also demonstrates an intervention, that Canadian government has played in stimulating the Canadian economy when it needed it most. Accordingly, Canada today represents a model to be emulated during the most profound global economic crisis since the Great Depression

Reagan and Gorbachev at Reykjavik, 1986 Essay Example | Topics and Well Written Essays - 1000 words

Reagan and Gorbachev at Reykjavik, 1986 - Essay Example Hearing someone say something, even through an interpreter, hearing their tone, seeing their body language, is much better than any e-mail, phone call or letter. Friendships can be developed and communication levels would have been at their optimum. However, no definite agreement in writing was reached at this meeting. Was it therefore merely a non-event? The Reykjavik summit is chiefly remembered for what almost occurred there, what might have happened. Is it possible for something that didn't happen to be significant historically? If it is to be classed as a non-event does that mean that it is significantly different from an event that actually took place i.e. the signing of an actual bi-lateral agreement. Is the historical significance of a non-event inevitably different in character from the significance of an event that did actually occur? This essay will consider this question. Firstly the American administration considered Reyjavik to be only a preliminary meeting, taking thei r cue from Gorbachev’s letter perhaps1, a response to an earlier one from President Reagan. In it the Russian asks only for a very brief meeting where mutually agreeable solutions could be discussed based upon a political will on both sides to succeed in bringing the arms race between the two powers to a peaceful conclusion. It wasn’t expected to be that important. However it is clear from transcripts of their conversations that other topics such as human rights were on the table and perhaps these add to the significance? The list of topics to be covered provided by the American Secretary of State 2certainly saw a decision to have arms talks as being a possible outcome, rather than actual talks. So this was part of a process which would eventually lead to disarmament. This means that this was not a non-event , but the beginnings without which the rest of the process could not have continued. It laid foundations upon which both sides could built . Gorbachev was very ope n. As Document 93 makes clear he was willing to discuss whatever topics Reagan introduced, not just nuclear weapons and possible future disarmament. Also despite the final failure to come to a definite agreement Gorbachev was able to return home and say ‘You see, Reagan is a man we can work with.’ 4 Despite this it seems from Document 6 5that the Soviet reason’s for calling the meeting had been completely misunderstood in Washington. They give a number of possible reasons, but seem to have no way of knowing which is correct. Also, according to Document 7,6 they seem unsure as to how President Reagan should react. The two leaders were able to meet face to face for several days. Their meeting had been originally planned to be a preliminary discussion, as shown by Gorbachev’s letter to the American President in October 1986, but in the end, verbally at least, they agreed bilaterally to greatly reduce their arms, including both nuclear and ballistic weapons. T he agreement later floundered however over details. According to Sokov7 the preparations had been poor and negotiations were disorganised . So politically was this a non-event? George Shultz, the then American Secretary of State had brought the two men together. He is quoted by Sokov as having said :- I suppose that what startled people in Reykjavik was not what was said, because both Reagan and Gorbachev had

Pneumonia Essay -- Papers

Pneumonia Pneumonia is a serious infection or inflammation of your lungs. There are two main types Pneumonia one of these is bacterial pneumonia. This can attack anyone from infants to the very old. People who are alcoholics, debilitated, post-operative patients, people with respiratory diseases or viral infections and people who have weakened immune systems are at greater risk. Pneumonia bacteria are present in some healthy throats. When body defences are weakened in some way, by illness, old age, malnutrition, general debility or impaired immunity, the bacteria can multiply and cause serious damage. Usually, when a person's resistance is lowered, bacteria work their way into the lungs and inflame the air sacs and a person's temperature may rise as high as 105 degrees F. The other one is viral pneumonia. Half of all pneumonias are believed to be caused by viruses. More and more viruses are being identified as the cause of respiratory infection, and though most attack the upper respiratory tract, some produce pneu...

Finding Nemo Essay

Finding Nemo is a film where a clown fish named Marlin living in the Great Barrier Reef loses his son, Nemo at a school excursion to the open sea. After Marlin’s despite warnings about the danger of the sea, Nemo gets taken away by a bunch of divers taken back to a Sydney dentist office. When his son was taken away from him, Marlin goes on a journey to rescue him. Throughout the journey Marlin has his up and downs but in the end he learns how to not be afraid and to let go and believe through humour from Dory, a lost fish he met at the start of his journey. A journey is defined as a transition from one place to another and Finding Nemo directly relates to this from its plot line, a physical journey from point A to point B and how much Marlin changes on the journey. At the start of the film he is a cautious father, understandably though as Nemo is the only offspring he has left after a shark ate his wife and all their eggs. Marlin does everything to keep his only son safe and sets out clear boundaries. Once his son is captured Marlin goes to extreme lengths to get him back and on the way changes as a person. He meets all sorts of animals he never though he would meet or see and learns from each and every one of them. For example, Dory, a lost and confused fish who has no real direction in life due to her terrible memory and absent presence of mind. Dory miraculously remembers everything when she is around marlin and proves to him that not everything is as bad as it seems and to look at the bright side of life instead of only the negatives. An example of this is â€Å"P.Sherman 42 Wallaby Way, Sydney†, the location of Nemo. Marlin was only looking at the negatives of the situation like the distance getting there, the fact that they might get eaten, losing their way and ending up in the middle of the sea instead, being stuck with a lunatic who will not let him be by himself for any period of time and not reaching his son whilst dory provides a positive aspect to the film with her cluelessness and innocence. Dory becomes an influential character because she shapes Marlin’s way of thinking through her speaking manner, recklessness and her willingness to try new things. Dory’s humour allows marlin to let go and believe in fate. An example of this is comparing Marlin at the start to the end of the text. At the start he is dull, boring and only concerned about his boy, when asked to tell a joke to Nemo’s friends’ Dads he responds with a terrible, boring joke that no one finds humorous. He treats the dads with complete disregard doesn’t try very hard to communicate with them. A changing for all this was the run-in with the sword fish, they told Marlin outright he was being rude to Dory and he should always remember to take care of her.

How Much Is the Nobel Prize Worth

The Nobel Prize honors scientific research, writing and actions that the Nobel Foundation feels exemplify service to humanity. The Nobel Prize comes with a diploma, medal, and cash award. Here is a look at how much the Nobel Prize is worth. Each year the Nobel Foundation decides on the cash prize awarded to each Nobel laureate. The cash prize is 8 million SEK (about US$1.1 million or â‚ ¬1.16 million). Sometimes this goes to a single individual or the prize may be split between two or three recipients. The exact weight of a Nobel medal varies, but each medal is 18 karats green gold plated with 24 karats (pure) gold, with an average weight of around 175 grams. Back in  2012, 175 grams of gold was worth $9,975. The modern Nobel Prize medal is worth in excess of $10,000! The Nobel Prize medal may be worth even more than its weight in gold if the medal goes up for auction. In 2015, Nobel laureate Leon Max Ledermans Nobel prize sold at auction for $765,000. Ledermans family used the money to pay for medical bills associated with the scientists battle with dementia. The Nobel Prize garners prestige that translates into value for the university or institution affiliated with the laureate. The schools and companies are more competitive for grants, better equipped at fund raisers and attract students and brilliant researchers. A 2008 study published in the Journal of Health Economics even indicates Nobel Laureates live one to two years longer than their peers. Learn More: How Much Is an Olympic Gold Medal Worth?
