Web Hosting - Managing Disk Space
Few things are less exciting than managing the disk space that always seems to be in too short a supply. But few things are more important to the health and well being of your site.
The most obvious aspect of managing disk space is the need to have enough. If you have only a few dozen web pages, that's not an issue. But as the amount of information (web pages, database content and more) grows, the quantity of free space goes down.
That's important for two reasons.
All permanent information on a computer is stored on hard drives. Temporary information is often stored in memory only. The two components are completely separate, though they are sometimes confused with one another. As the amount of free space on the hard drive decreases several effects occur.
Here's one way to picture them...
Imagine you had a table with a certain area and you lay out playing cards on the table. At first, you lay them out in order, the 2 at the side of the 3, then 4, and so on. But then you pick up one or two cards from the middle and discard them. Then you add some more cards. Pretty soon things look pretty random.
Now cover the cards with a big opaque sheet of paper.
You want the cards to appear in order when displayed to someone. A special robot could be designed to always pick up the cards from underneath the sheet in order. Or, it could slide a hole in the sheet over the cards to display them in the correct order (2, 3, 4, ...), no matter what order they are really in. That's similar to how the operating system always shows you information in a sensible way, even though it's actually stored randomly.
Why should you care?
Real files are stored in pieces scattered around the drive wherever there is space for them. The more free space there is, the quicker the operating system can find a place to store a new piece. That means, if you delete the junk you no longer need (and free up more space) the system actually runs quicker. It helps create space you might need, and allows the operating system to store files for you faster.
But there's a second effect.
As you delete old files or change them, the pieces get more and more scattered. It takes the 'robot' longer and longer to fetch or display the 'cards' in order. Existing files are fetched and put together 'on the fly' (say, when you request a graphical page or a list of names). But, it takes longer to put together the web page when there are more scattered pieces.
So, the other aspect of managing disk space is to keep the pieces of the files more or less in order. A utility that does that is called a 'de-fragger' or de-fragmentation program. You can request that a system administrator run it, or if you have the authority, you can run it yourself. That keeps the 'cards' in order and allows for quicker access to them.
So, managing disk space involves chiefly three things: (1) keeping enough space to store what you need to store, and also (2) keeping enough free space to make new file storage quick and (3) making old file retrieval fast by keeping things orderly.
When only a few files are involved the benefit isn't worth the effort. But as the number and size of the files grow, to thousands of files or several gigabytes of data, the effect becomes more noticeable. Keeping things organized then makes a significant difference in performance.
Much of this can be automated using utilities. Some will delete files in a certain folder older than a certain date. A de-fragger can be set to run automatically during times of light usage, or quietly in the background at all times. Discuss the options with your system administrator and help him or her do the job better by keeping your house in order. You'll benefit by having a better performing web site.
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? Copyright music Copyright Music in Order to Protect Future Profits If you are a budding artist seeking to copyright music that you have labored over, there is good news. Many people confuse copyrighting music with registering music and they are two different things. According to the law in the United States, once you have written or recorded your music in a permanent form, it is copyrighted. Of course, it might help to first understand what it means to copyright music in the first place. A copyright is a certain legal protection that is offered to those who compose creative works. Whether those works be art, music, or the written word. According to the U. S. constitution there are limits that can be placed on the amount of time that the work is exclusively protected. If you copyright music, this means that you and you alone have the right to use your work or allow others to use your work. You also have the right to distribute copies of your work. Whether those copies are in the form of written or sheet music or recorded music to the public as well as the right to perform your music for the public. There is something called fair use that despite your copyright; music written or recorded by you may be used for the purpose of research, news reporting, commentary, or criticism. In other words, there are times when the use of copyrighted material is deemed appropriate without the consent of the one holding the copyright. To copyright music alone is not enough in many cases to protect your music, at least not without going through a lot of hoops in order to do so. One of the things you can do in order to protect your copyright is provide notice of copyright. This is a simple step that includes writing a simple statement to the effect of the word "copyright", the date, and your name at the bottom of your sheet music or on the case for the recording or the actual recording itself. CD's are the most common means for recording devices today and a notice of copyright can easily be added to the exterior of your CD or on your label if you have one printed. In case you are wondering: why copyright music? The answer is rather simple, so others cannot take credit for your creative genius. For an added layer of protection you may want to consider registering your copyright as well. Registering your copyright will provide you with formal legal documentation of your ownership of your music should anyone else attempt to lay claim to your music or any other dispute about true ownership/authorship come about. You must have your copyright registered if you wish to file a copyright infringement suit and it is, in my humble opinion, better to not only copyright music early on but also to register your copyright before it could possibly become an issue. Registering while not entirely painless is not as difficult a process as you might think. Basically it involves filling out an application, paying a filing fee (check with the U. S. Copyright Office for the current amount), and a copy of the work being protected (this will not be returned). It's also important to remember that your music doesn't have to be published in order for you to obtain a copyright. Music should be copyrighted and registered long before the publication process in order to protect your rights as the creator of the music. Whether you are dabbling with cute little limericks or writing masterpieces and concertos or are rock and rolls next super star you want to make sure to copyright music earlier rather than later for the best possible outcome should problems arise. |
