Web Hosting - FTP and Other File Transfer Tools Anything related to the Internet or computers is bound to introduce technical issues pretty soon. One of the earliest that novice web site owners encounter is FTP, which is an acronym for File Transfer Protocol. Seeing it spelled out, it's easy to see why those in the know quickly move to speaking in short hand. The reason web site owners soon will (or need to) become familiar with FTP is obvious to anyone who has built a site on a remote server. You have to have some way of getting the files to the remote computer and FTP is one of the most common tools. It's also one of the simplest and most efficient. FTP is composed of two parts: the client software and the server software. It's similar, in a way, to talking to someone on the phone who writes down everything you say. You (the client) make a request ('transfer this file to the server') and the listener (the server) takes the request and acts on it. That request to copy a file from a local computer to the remote one is carried out (often 'under the covers') by a PUT command, as in PUT this there. You create the web page (in the form of a file) and then PUT the file on the server. To move a file in the opposite direction, from the remote server to your local computer, your client software issues a GET command. Many FTP clients have graphical interfaces, similar to Windows Explorer, that allow you to drag-and-drop or otherwise copy the file without ever seeing the actual commands that carry it out. But it's helpful sometimes to know what goes on underneath. In tricky cases it can be an advantage to use a command line interface (in Windows, the 'DOS box', with a similar interface familiar to most Linux users). Knowing the commands and being able to use them in the command line form can sometimes help you diagnose what is going on when the graphical tools misbehave. But FTP is not the only way to get a file from here to there. In fact, your browser moves files around from a remote computer to your local one all the time. In most cases, when you type in or click on a URL, what happens under the covers is in essence a file transfer process. The web page is transferred from the web server to your local computer then displayed by the browser. Alternatively, you can sometimes even email a web page/file from your local computer to the remote server, then use an email client on the server itself to get the file and put it in a folder. That requires that you have some form of access to the remote computer. But there are many ways of doing that, such as in-built utilities in the operating system or using commercial remote control programs. Those alternatives can be helpful to know in cases where the FTP file transfer process is misbehaving. Having more than one way to accomplish the task helps you diagnose what might be going wrong. It also helps you get the job done when the usual tools aren't cooperating. The more you learn about these sometimes puzzling acronyms, the easier you can accomplish your own goals.

Free Copyright Music Free Copyright Music Means Deeper Well for Artist Inspiration Free copyright music is often mistaken with domain free music or music in which the copyright has expired. A copyright is in place for the lifetime of the author plus 70 years. If there are more than one writer's for the music, the copyright will be in effect for 70 years after the death of the last surviving contributor. While this rule was set in place in order to ensure that the heirs of the author would also benefit from the royalties after the music's writer or composer was no longer living it is important to remember that these laws are the current laws and music written at different points in time are most likely subject to different copyright laws. When searching for free copyright music it is always a good idea to search through music that is very old rather than focusing your search on more recent musical selections as they will most likely still be under copyright protection. It is important to remember when using free copyright music or public domain music that you must be certain the copy you are using is within the copyright period. Any music that was published before 1922 is public domain music. This does not however include derivatives or new versions of that music which may still be under copyright protection. Finding a copy of the music with the copyright date included, if that date is prior to 1922 is the best route to ensure that you are in compliance with current copyright laws and not infringing on someone else's copyright. It is also important to keep in mind that written music is protected differently than recorded music. Almost every sound recording that has been copyrighted in the United States is protected until 2067. If you absolutely need a sound recording you should either purchase one or make one of your own. There are some free copyright music that will allow free use of the music whether written or recorded, you must be thorough in your search for this music however as it quite rare. Another thing to consider is that copyright laws in the United States are different than they are in other countries and if you wish to use music that is or was under copyright in another country you must follow the laws that apply to the particular piece of music you wish to perform. Free copyright music is available in almost every country and many genres; the trick is in finding great sources where you can easily find this music. There is a project called Mutopia, which operates like project Gutenberg. Mutopia provides free copyright music rather than books however. The Gutenberg project also has a section that is devoted to free sheet music in addition to its wonderful resources for books. Each of these projects provides excellent resources for those who find themselves in need of free copyright music for whatever reason. Whether you are a musician who is seeking inspiration from the music of old or hoping to find a composition, which you can rearrange and make your own, there are many ways in which you can go about achieving your goals that will not violate current copyrights. The key is in learning the laws both where you live and in any countries in which the music you seek to modify. By choosing selectively and listening to your options with an open mind and seeing things with a creative eye, you will find a huge world of opportunity available to you as a musician. Isn't it amazing how free copyright music can have such an effect on your ability to create music that you may someday copyright?

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.
