Web Hosting - Redundancy and Failover
Among the more useful innovations in computing, actually invented decades ago, are the twin ideas of redundancy and failover. These fancy words name very common sense concepts. When one computer (or part) fails, switch to another. Doing that seamlessly and quickly versus slowly with disruption defines one difference between good hosting and bad.
Network redundancy is the most widely used example. The Internet is just that, an inter-connected set of networks. Between and within networks are paths that make possible page requests, file transfers and data movement from one spot (called a 'node') to the next. If you have two or more paths between a user's computer and the server, one becoming unavailable is not much of a problem. Closing one street is not so bad, if you can drive down another just as easily.
Of course, there's the catch: 'just as easily'. When one path fails, the total load (the amount of data requested and by how many within what time frame) doesn't change. Now the same number of 'cars' are using fewer 'roads'. That can lead to traffic jams.
A very different, but related, phenomenon occurs when there suddenly become more 'cars', as happens in a massively widespread virus attack, for example. Then, a large number of useless and destructive programs are running around flooding the network. Making the situation worse, at a certain point, parts of the networks may shut down to prevent further spread, producing more 'cars' on now-fewer 'roads'.
A related form of redundancy and failover can be carried out with servers, which are in essence the 'end-nodes' of a network path.
Servers can fail because of a hard drive failure, motherboard overheating, memory malfunction, operating system bug, web server software overload or any of a hundred other causes. Whatever the cause, when two or more servers are configured so that another can take up the slack from one that's failed, that is redundancy.
That is more difficult to achieve than network redundancy, but it is still very common. Not as common as it should be, since many times a failed server is just re-booted or replaced or repaired with another piece of hardware. But, more sophisticated web hosting companies will have such redundancy in place.
And that's one lesson for anyone considering which web hosting company may offer superior service over another (similarly priced) company. Look at which company can offer competent assistance when things fail, as they always do sooner or later.
One company may have a habit of simply re-booting. Others may have redundant disk arrays. Hardware containing multiple disk drives to which the server has access allows for one or more drives to fail without bringing the system down. The failed drive is replaced and no one but the administrator is even aware there was a problem.
Still other companies may have still more sophisticated systems in place. Failover servers that take up the load of a crashed computer, without the end-user seeing anything are possible. In fact, in better installations, they're the norm. When they're in place, the user has at most only to refresh his or her browser and, bingo, everything is fine.
The more a web site owner knows about redundancy and failover, the better he or she can understand why things go wrong, and what options are available when they do. That knowledge can lead to better choices for a better web site experience.
People caught of copyright infringement Why Are People Caught of Copyright Infringement? When you hear of people caught of copyright infringement, many different things can happen to them. First of all, copyright infringement is both a civil and criminal crime, so people caught of copyright infringement are likely to get both sued and tried in criminal court. Because of the nature of copyright laws, if and when people are caught of copyright infringement, it?s likely that they will get repercussions from far and wide. First of all, people are always looking for people violating copyright laws. Copyright owners and/or agents surf the internet, so they may find the violations themselves. Usually, is someone finds that people are violating their copyright rights, they?ll notify the person or entities involved and ask that they take the content down, if it?s available on the Internet. They do this by either asking the person directly to take it down, or demanding of the website server to take it down (which they will, immediately, and probably suspend the account) If the person or entity hosting the violation doesn?t take it down, more serious actions will be taken, such as a lawsuit or criminal charge. People caught for copyright infringement do not automatically go to jail, although some entities like major television, music, and movie publishers and distribution channels may lead you to believe otherwise. For the example of YouTube.com, there are many people caught for copyright infringement, but they only need to take down the material. In many cases, YouTube.com will take the material down before the poster (the person who put the copyrighted information on the site to begin with) has a chance to see the warning. Other times, a work will be present on a peer to peer file sharing service, such as Kazaa or Napster, and the host of said service will blame the end user (you!). So, even if you found a file on a file sharing service, such as Kazaa, doesn?t mean the copyright is open for you to take it. Many people caught of copyright infringement have been found through these peer to peer networks, and it has been found time and again that the user that downloads the material gets charged and not the file sharing service. Be careful, if you are ever to use a peer to peer service such as Kazaa (or bit torrent, which is the code/program for another type of peer to peer file distribution tool) that you?re only downloading, and sharing, items that aren?t copyrighted works ? or you could be punished severely. Sometimes, people are caught of file sharing from their IP addresses ? because they download something from a secure site, their servers can track your IP address (your unique location on the internet, four sets of numbers, separated by periods, with at most three numbers in each set ? i.e. 22.214.171.124 which is the IP address of Google.com). So even if you think you?ve bypassed the copyright law, you can still be found years later by tracing that IP address. There are many ways to find people caught of copyright infringement, you can search through Google.com or look through newspaper databases. One thing, however, remains the same in all these cases ? the people are downloading, sharing, or in some other way using copyrighted materials. The only problem is, especially in the internet age, is that even if you?re using something anonymously, you can still be tracked ? and prosecuted ? for the infringement. Be careful, in all you download or use, have the rights to use the item ? sometimes it?s as simple as asking permission that will keep you from getting sued or sent to jail.
Copyright infringement case Learning Copyright Law through Copyright Infringement Cases Copyright infringement cases can be both costly and time consuming. Considering copyright infringement is something that isn?t as easily defined as theft or speeding, there are numerous copyright infringement cases that are changing the way copyright law is viewed in the United States of America. By reviewing a few of these copyright infringement cases, you?ll be able to get a better idea of what is, and is not, acceptable use of copyrighted works. As a forward, however, you?ll need to know a little bit about copyright law. Most copyright lawsuits are brought to the courts because a copyright owner has found their copyright is being used outside the copyright laws. This usually means that the copyright holder hadn?t been asked for permission to use the work, or if they had, that the work is not being used in an agreed-upon context or they have not been paid royalties. The copyright infringement cases, listed below, give a sampling of what goes to the Supreme Court in copyright infringement. Feist Publications v. Rural Telephone Service Co (6th Cir. 1996) This copyright infringement case was brought upon the Supreme Court in 1996 regarding the copyright of a database. The supreme court, in this instance, decided that compilations of data (such as in a database) are only protected by copyright when they are ?arranged and selected in an original manner.? Although the level of originality needed to make the database copyright-able is not very high, the pages of a directory such as a phone book are not protect-able because the data contained therein is arranged geographically, then alphabetically. Because of this, the data was not original enough to warrant a copyright infringement charge, and the competing telephone company was allowed to tap into their competitors? database and use that data in their own work without liability. Princeton University Press v. Michigan Document Services, Inc (6th Cir 1996) This case has to do with the ?fair use? law, which is defined in the Copyright Act of 1976, 17 U.S.C. § 107. In this case, a photocopying service was sued for copyright infringement for making ?course packs? for the University of Michigan. In this case, a course pack was a group of reading materials assigned by a professor ? then the course pack was bound together by a professional copy shop. In the fair use system, there is a system available for payment of copyright fees to publishers whose works are used in course materials, the printing shop owner refused to pay the copyright cost. When it went to the Supreme Court, they analyzed the fair use code and found that it was NOT fair use, and the printing shop had to pay the copyright costs. As you can see, copyright infringement cases are cases in which someone violates the rights of a copyright owner, as provided by 17 USC §106, or of the author as provided in §106A. These copyright infringement cases can be taken to either criminal or civil court, and can carry with it a hefty fine. Copyright infringement cases are brought upon people who violate copyrights every day. In recent times, you?ll find many copyright cases in relation to electronic copyrights ? such as those you?d find on a website or PDF file, as well as other digital media such as music and audio files. It?s probable that you?ve seen copyright cases brought against the common person ? such as a child or family ? for downloading digital music in the form of MP3s. In the current internet age we?re in, it?s not surprising to see so many music and video copyright cases brought to us because of peer to peer file sharing made possible by the internet. You can be certain that until people know the rules of copyright, and downloading copyrighted material from the internet that we?ll see many more copyright cases.
Turning your Eye to Government, Nonprofit or Small Business for you Next Job The type of business you work for can effect your job satisfaction. Your personality type may also work out better at certain types of businesses. Research different business types before going on your job search. Working for a small business or a non-profit definitely has its pros and cons. First of all, getting hired at a small business can be much easier than landing a position than at a corporation. Typically you will only have to go through one person to get the job. Usually the small business owner conducts the interview. This can be a good thing because the business owner may be willing to overlook a lack of experience or extenuating circumstances concerning your work history. Nonprofit jobs are often easier to get if you are passionate about the cause. The person that is doing the hiring is generally passionate about the cause that the nonprofit is working to assist. If they pick up on passion about the cause from you, typically you will get the job. However, that passion is necessary because they pay may not be very much. Working for a smaller company also opens up more opportunities for promotions. With fewer employees and contact with the owner, you may be able to move up in the company faster. You will be able to pick up on skills in less time than at large corporations, which often have many hoops for one to jump through before training for a new position. There may be a smaller window of time to pick up on new skills because of the limited amount of time that can be put towards training. Nonprofits may not have as many opportunities for promotions and job stability may be questionable. If the donations stop coming in or whoever funds the nonprofit decides not to fund it anymore, you could be out of a job. This is a very real concern with a nonprofit job. There are some drawbacks to working at smaller businesses. Sometimes, the staff at smaller businesses have been in place for years. New, younger employees may not be viewed favorably. This could affect working relationships with co-workers. Smaller companies also mean smaller paychecks. Independent businesses are not able to generate large paychecks. This could make staying at a small business undesirable. However, the personal interaction between you and your boss could be encouragement to stick it out with a small business. Or the opposite could be true. Government jobs can be beneficial to have for a number of reasons. First of all, government jobs offer good salaries and great benefits. You will have all government holidays off and you will be working in a position that is necessary to the maintenance of the government. That means that you probably won?t have to worry about being displaced. Although, remember that if the government runs into tough times, layoffs are possible. Government jobs are usually normal business hours but not always. There are some positions that will have hours that extend a little bit beyond regular business hours but for the most part, you will be able to enjoy your life by taking advantage of vacation time. Sick days will also be available at government jobs. Some of the drawbacks of government jobs are that you may have to deal with a large amount of on the job stress. You may be responsible for processing hundreds, maybe even thousands of cases and one mistake could be very tragic for an individual. Depending on what your position is, you may be instrumental in handling paper work from a huge amount of people.
