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.

Can Facebook or MySpace Help You Land a Job? The Internet is quickly becoming the vehicle of choice for people looking for a job and for employers looking for people to hire. There are many job sites on the Internet dedicated to matching up employees and employers, and most people turn to the Internet today when they are hunting for a job instead of turning to the classified ads in the local paper. Job hunting websites may all be well and good when you are looking for a job, but what about social networking sites. Everyone knows how popular sites like Facebook and MySpace are online, but can they help you get a job? If you are in the job market, can these sites be your foot in the door, or a one way ticket to the unemployment line? The answer is that there is no easy answer. To know if you can find a job using Facebook or MySpace, you have to know how employers feel about these sites, and employers have mixed feeling about them. Some companies are actively using social networking sites to track down employees that meet their company’s employee profile and have had great success finding workers via social networking sites. Other companies wouldn’t touch these sites as a hiring tool with a ten-foot poll – in fact, many companies don’t even want you to access these websites from their company computers. The real answer to this question has more to do with exactly what kind of job you are looking for. Are you looking for an executive position at a company? Then stay off of the social networking sites, at least for job hunting (and maybe all together). No company is going to look for its top brass on a social networking site, and you will be wasting your time. However, if you are looking for entry level or hourly wage work, the social networking sites like MySpace and Facebook may be the answer for you. Many hourly wage employers in particular, like fast food restaurant chains and mall stores, use MySpace and Facebook to look for potential employees in their area. If a potential employer sees your profile and thinks you may be a good fit for their company, they will send you an email or an instant message and get the ball rolling. You should also, however, carefully consider the downsides of using social networking sites as a job tool – and you should carefully consider how and if you use these sites at all if you are in the market for a new job. Most people wouldn’t want their parents to see their social networking site profile, let alone potential employers. If you have rude and off color material, political or religious material, and inappropriate photos of yourself on your profile, a potential employer will be turned off, and you might lose your chance at that job. Most people give up way too much of their privacy when they use these kinds of sites, and your social networking site profile may offer a window into a side of you an employer might not be overly impressed with. Further, you can open yourself up to danger by using these sites to job hunt. If someone approached you in the street and offered you a job, would you accept? Then why would you accept a face value an approach by someone on social networking site? If you do get approached for an interview, never meet anyone in a private place, and do your homework to make sure the facts check out before you go for the interview. One last reality check – there are over 60 million users on MySpace alone. How will an employer find you in the crowd? MySpace and Facebook may help you in your job hunt, but don’t count on them as your sole avenue into the job market.

Copyright music expiration For Many Copyright Music Expiration is a Luxury for Worry If you copyright music, expiration isn't something you have to worry about, at least not in your lifetime. The music that you've written is copyrighted the moment you've put it onto paper or recorded it being played. The reason you don't have to worry about expiration is because the music is protected until 70 years after the death of the author. In the case of your music, that author would be you. This rule about copyright music expiration was first put into place so that the families and heirs of an author could still earn royalties even after his or her death. Ultimately this means that if you've taken the steps to copyright your music and have registered the copyright then your music will be protected throughout your lifetime until 70 years after you or the last surviving author (assuming a collaboration) are no longer living. Copyright music expiration is not something you should make a primary concern unless you are having issues of someone respecting and/or honoring your copyright at the moment. You should take comfort in the fact that as long as you are alive you are the only one who can assign your copyright to another person and as long as you haven't given up your ownership of the music it still belongs to you. This is different however if your copyrighted music was work made for hire. If that is the case then you cannot have ownership of the music, as it never legally belonged to you no matter what form it was in when it changed hands. Works made for hire have different copyright music expiration than those that were owned by the creator. With works made for hire, the copyrights are in effect for 95 years from the original publication date or for 120 years from the creation of the work whichever of the two is shorter. For most beginning musician’s copyright music expiration date isn't as important as getting that first gig or earning that first dollar as a result of the music he or she writes and/or plays. It's about art for many and about survival for others. The latter are quite often the ones that are taken advantage of. These are the authors who don't protect themselves as they should and end up failing to register their music because the idea of buying food seemed more pertinent to survival at the moment. This is often the case, particularly among street musicians and it's something that was becoming a growing problem immediately after hurricane Katrina devastated New Orleans taking with it many of the homes of starving musicians along with many pieces of music that will never become copyright music, expiration or not, those works are gone forever except in the mind of their creators. who could barely scrape together the money to pay $100 a month for a hovel they shared with 6 or 7 other people in order to keep expenses down and avoid living on the streets. The building not only of homes for those musicians displaced as a result of Katrina's devastation is wonderful but even more than that is the fact that there are organizations that are dedicated to creating a community for these musicians so that maybe many of the struggling artists won't be taken advantage of or have to face the decision to register their music in order to protect and copyright music expiration for their future heirs or to risk loosing their claim over the music they wrote in order to eat or pay the rent or buy groceries.
