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.

Why Taking that Vacation Can Lead to a Better Workplace Do you love your vacations? Are they relaxing, fun and entertaining? There are many reasons why a vacation can enrich your life and fulfill you with joy and happiness. But many of these reasons actually can also be directly translated into reasons for why taking that vacation can lead to a better workplace for you, your boss and other employees. Vacations are as essential to a hard working employee as a parachute to a person jumping from an airplane with the goal to land safely. Many employers would love to minimize the time you are gone from your workplace because they think the more time you spend there, the more work you will accomplish. This argument is right up to a certain amount of hours and days a months or a year, but whenever your body starts to get tired and exhausted, the amount of work that you produce decreases. The quality of your work starts to decline as well. Time off work, time together with your family, time to relax, time to regenerate and time to just plain have fun are very important in an employees life. Taking a vacation has many benefits to the employee, but also to the company you work for. The more relaxed and happy your worker starts a workday or the workweek; the better will most likely be his or her performances at work. Research has shown that relaxation and regeneration are essential to human bodies. Did you know that in some companies in Europe and Asia, the emphasis on relaxation goes so far that meditation, morning sport and a short power nap belong to their required parts of a work day? The United States is actually one of the only industrialized countries that does not mandate a minimum of vacation days that the worker has to take off. In fact, in many countries in Europe, a minimum of 20 and more days is the norm. Since the late 1970s, the average middle income family works in total hours three and more months a year more then they did back then and according to a research done by Boston College, approximately 25% of Americans do not take a vacation at all. After all these facts are slowly emerging from mounts of collected date, some of the bigger American companies have actually begun to realize that off-time and vacation are essential to prevent mishaps and screwed up designs and products. If you are not taking your vacation or your employers does not allow for any vacation, a series of health hazards such as stress and high stress, sleeplessness, burnout, heart attacks and even more serious health conditions can occur. Another big factor in working too much, working overtime or never having vacation can be problems and loss of family and friends. Problems with families and friends will directly impact performance at work and even though the employee might not talk about it at work or might b e holding back his or her feelings, the mood and general behavior of the employee will have an impact ion his work and other employees. Every employee should value the vacation time given to him or her and employers should grant the time asked for to their employees. Vacation is essential to the performance at work and the quality in products the company can deliver. Following the examples that are set by many European countries, the US should give their employees the time they need and also make sure that their employees do take the time off to be a better employee overall. Vacation is fun, relaxing and regenerating.

Copyright Infringement Statistics Copyright infringement statistics, by most standards are inflated. Most recent copyright infringement statistics cite that almost 30 percent of software is pirated in the United States of America. This means that they think 30 percent of the software on your computer is illegal… they think we’re all thieves, to an extent. However, copyright holders have good reason to worry that we’re violating their rules: the number of suspects referred to the United States attorneys with an Intellectual Property lead charge increased twenty six percent in the period between 2002 and 2004 – and there have been studies that show that this is rising. Copyright infringement statistics are difficult to come by, but it’s plain to see it’s affecting every aspect of intellectual copy. Copyright infringement statistics show that in addition to software privacy, there are a lot of violations in the music world. Copyright infringement statistics show that many unsuspecting people, from college students to thirty-something a professional, download music on a consistent basis, and often it’s not downloaded legally. Often times, someone will download a song off a MySpace or YouTube page, without giving thought to who really owns the copyright and if it’s legal for them to have it. Copyright infringement statistics, brought to us by the music recording industry, would have us believe that online infringement is seriously hurting the recording industry. A sensible person, however, would realize that with the abundance of MP3 sales sites that this will turn quickly and recording giants will see the huge profits available online. It’s already begun, you see, we have yet to see the impact of online music sales, and how it will increase revenue. I’m sure, with the huge talent pool at their disposal, the media giants will find a way to monetize the internet to their fullest advantage. Copyright infringement statistics also show that many people are downloading games off the internet. With the litany of games available to us – from complete alternate worlds such as World of Warcraft to the more mainstream “The Sims” series, people are clamoring for PC games – and for good reason. They’re fun, intelligent games that play on a system everyone has – a computer. Because of this, people are always looking for new games to play and download, and they may download a game without knowing that it’s not ‘freeware’ (as many internet games are). In addition to computer games, copyright infringement statistics also show that movies are downloaded in abundance on the internet. Many peer to peer file distribution sites and programs (such as bit torrent or Kazaa) allow for the transfer of very large files, and they’re easy to find online. Using a tool provided by one of many suppliers, users can search for any item they like – and, of course, the system is abused and people download copyrighted movies and entire DVDs instead of publicly available works. Copyright infringement also branches into written works, such as articles, books, poems, etc. Many times, a student will copy a paragraph or two without realizing the implications of such copying. While they may think of it as ‘borrowing’, if it’s used on a grander scale, the person could be opening themselves up to a large court fight, especially if it’s used commercially. As you can see, copyright infringement statistics show us that many people are using copyrighted works illegally. Do your best diligence when using another’s work – and ask for permission every time you want to use something that you haven’t created. Chances are, if you just ask the question up front you’ll save yourself from becoming another copyright infringement statistic and save yourself from a major lawsuit.
