Web Hosting - Domain Name Changes and How They Affect You New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it. When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties. One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another. Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here. DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low. In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was. A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed. The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world. Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching. In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data. A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed. Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random. But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies. That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely. In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address. So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.

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 Music Form The Copyright Music Form is your First Step to Protecting your Work Many confuse a copyright music form with an actual copyright. The form is actually what you get from the U. S. Copyright Office when you are ready to register your copyright. It is highly recommended that everyone who writes a piece of music take the time and register their copyright. It is also important to understand that once you've either written or recorded your original music, it is actually copyrighted. In other words you do not actually need to fill out any type of copyright music form in order to have your music copyrighted. While registering is not the act of copyrighting your work it is very necessary if you plan to file suit for copyright infringement. It is also better to fill out the copyright music form they offer earlier in the life of your music rather than later as the timing of the registration of your copyright can have an impact on the actual awards you can receive should you win your lawsuit. There is also something quite satisfying about having your musical works registered with the copyright office. I can't explain the feeling as it will be different for everyone but if you've written music, you really should see for yourself. You can find the copyright music form from the U. S. Copyright Office online quite easily. There is more involved than simply filling out the paperwork in order to register your copyright. You must also pay a fee, the actual fee changes so you should make sure you are aware of what the current fee is before sending in your work. An insufficient fee can result in delays. You also must send an actual copy of the music you are registering the copyright on. Your copy may either be the written or recorded music you wish to register but must include everything you wish the registration to cover. When filling out the copyright music form it is important to provide as many accurate details as possible. While your registration is active the day your application is received you may not actually receive your certificate for several months. Really and truly, as far as government agencies go, this is one of the easier ones to deal with as far as red tape. The procedure in addition to the copyright music form is straight forward and not designed in a manner that would be too easily confusing. The copyright music form is only one step in the process of registering your music's copyright. While it is an important step if you forget the other steps there will be delays in the registration process. Read the form completely before filling it out and if you are printing your form from the computer, I highly recommend printing more than one copyright music form to insure that you have extras if you make a mistake and in order to register your future musical copyrights. Your first copyright registration will be the most nerve wracking. This makes perfect sense when you consider that trying anything new requires some degree of 'anticipation'. It is also likely to be your most thrilling. Even in this particular piece of music ends up being the worst piece you've ever written (most of our first endeavors are our worst) there is a lot to be said about the fact that you've actually taken the steps to insure your future is a great feeling. If your first piece of music sells and is someday published that is wonderful. If not, you are still ready for the next piece and have gone through the process of filling out a music copyright form before so you know what to expect.
