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.

Patent and copyright law Understanding Patent and Copyright Law Patent and copyright law gives the inventor the exclusive rights to the invention. No one else can produce the invention for a set period of time under patent and copyright law. Patent and copyright law is set up to protect inventors. The law on patents can be found in the United States Constitution, Article 1, Section 8 and in Title 35 of the United States Code. The agency that is in charge of patent laws is a Federal Agency known as the Patent and Trademark Office. Anyone who applies for a patent will have their application reviewed by an examiner. The examiner will decide if a patent should be granted to the inventor. Individuals who have their patent application turned down can appeal it to the Patents Office Board of Appeals. Just because someone has a patent does not mean that they have the right to use, make or sell the invention. For instance, if a drug company comes up with a new drug, they can get a patent on it. However, it would not be available to be sold to the general public until the drug becomes approved by other regulatory bodies. Likewise, someone may invent an improvement to an existing product, yet they will not be allowed to produce or sell the item until they obtain a license to do so from the owner of the original patent holder. For someone to receive a patent, as stated, they must fill out an application on their invention. The application will entail the details of the invention and how it is made. In addition, the person applying for a patent must make claims that point to what the applicant deems or regards as his or her invention. A patent may have many claims with it. The claims protect the patent owner and notify the public exactly what the individual has patented or owns. If someone infringes upon patent and copyright law, it is usually enforced in a civil court setting. The owner of the patent will generally bring a civil lawsuit against the person who has infringed upon their patent and ask for monetary compensation. In addition, the patent owner can seek an injunction which would prohibit the violator from continuing to engage in any acts that would infringe upon their patent in the future. Many patent owners will make licensing agreements (or contracts) with others. These agreements allow another person or company to use someone’s patented invention in return for royalties. In addition, some patent holders who are competitors may agree to license their patents to each other to expand both of their profits. Most everything we use in our day to day life was invented by someone. That person had to seek out a patent for their invention. Patent and copyright law protects inventors from having their ideas and inventions stolen out from under them. This makes the playing field more level for individuals. Without these laws, the marketplace would be out of control and the small guy would probably be eaten alive by big business

What is copyright infringement What Is Copyright Infringement? The Layperson's Copyright Primer Copyright laws are constantly changing, and knowing exactly what copyright infringement is, whether you’re creating an eBook, publishing articles, using music as a backtrack to your podcast - or what have you - is essential to selling your online media. Although the laws change from one jurisdiction to another, knowing the basic rules of copyright infringement will ensure you’re following the proper rules of engagement when it comes to creating your works. Before you make any final decisions regarding the use of a work that has been copyrighted, please contact a copyright attorney to ensure you’re following the law – this will keep you from being sued or, even worse, punished in a court of law. What is Copyright Infringement? Copyright infringement, as defined by Wikipedia.org, states: “Copyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.” So, what is copyright infringement in plain English? It means that if you’re not allowed to use something, then don’t use it – plain and simple. It can be very simple to get permission to use a work – many times you’ll be able to use a ‘sample’ of music or excerpt of written work for a nominal fee, or small attribution. However, if you do not have the permission of the copyright holder – whether it’s an author or a publishing house – you can be sued for copyright infringement or worse. What is Copyright Infringement in America? In many jurisdictions, such as the United States of America, this act is known as a strict liability crime or tort (a tort is a civil wrong – not a criminal wrong). This means that the person who infringes the copyright - whether intentionally or not - will be responsible for the damage or loss. Also, the prosecutor (in criminal court) or plaintiff (in civil court) must only prove that the act of copying was committed by the defendant – they do not need to prove guilty intent. This means, even if you had no intention of committing copyright fraud or infringement, you can (and in present times, in many cases, WILL) be prosecuted, even if you used the material in good faith. What is Copyright Infringement in action? Many cases of copyright infringement are difficult to see to the layperson, because the violation is not limited to exact copying. In many cases, when something is inspired by another thing – such as in music, when the inspiration of one song is used to create an entirely different song – it’s difficult to see where the new product or ‘thing’ has crossed the line to something illegal. Some works aren’t even protected by copyright, such as compilation of facts that lack the creativity necessary to be covered by copyright, or works that are in the public domain because the copyright has expired. Knowing the difference is often very difficult to see, and because of this we’ve seen a number of copyright infringement cases in recent years, especially in tandem with the music industry. As you can see, copyright infringement is a very difficult, albeit necessary, act to define. However, if you make sure that you’re using works that are in the public domain, or have long since been out of copyright (think Beethoven or Frankenstein) you’ll be safe. Do you fair research, and if you have any questions contact a copyright lawyer and ask ‘what is copyright infringement’ to learn the most up-to-date information for your jurisdiction.
