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.
Software copyright sample Software Copyright Sample Builds Loyal Customer Bases When choosing software copyright sample many before focusing on one or two. It is impossible to try every piece of software that exists in the world of software today. There are so many pieces of software currently on the market and new software being created as I type this. With so many new and different, competing and interesting software programs so widely available you might find something wonderful and unique available at a wonderful price or better yet, for free in the open source arena. Open source software isn't exactly software copyright sample material. This software is occasionally used as a testing ground for unproven versions of software, for software testing, or simply to determine the demand for a particular type of software. Chances are pretty good however; that if you've ever thought, "I wish I could find a program that did (insert whatever here)" someone else has had the same thought and created a program that will do just that. Perhaps the greatest beauty of a software copyright sample is that you get a taste of what the software can do without the expense of purchasing to find out whether it is right for you or your needs. There are actually many ways that companies both for profit and open source companies allow potential customers or converts to sample their products. Linux is a great example of this. They have gone from an open source nuisance to a viable competitor to many larger software companies by providing free software or a software copyright sample to consumers in order to whet their appetites for future offerings designed with profit in mind. What has developed is a viable (and growing) source of competition for Microsoft. Many open source developers are operating very much like Linux and starting out by offering a free software copyright sample to those who will try them out and give them feedback. They use the feedback to make improvements and build better products while making a name for themselves, their customer service, and the quality of the products they build. It's a win-win situation for many consumers and businesses that are just starting out and operating on a shoestring on both the part of those that offer the software copyright sample and those that are benefiting from the sample. Other companies are not as altruistic or are not as willing to wait for the payoffs. Instead of offering a completely free software copyright sample, they will offer you a free trial to their software that will either end at the end of the trial period and require a new subscription or automatically begin charging your credit card. Both of these practices have proven themselves to be highly effective methods of winning not only new customers but also seemingly unshakeable customer loyalty on the part of those that purchase software from these developers or companies. If you do an Internet search for open source software I think you will be astounded at the quality and selection that exists. There are programs that exist to do almost anything. My favorite (I must admit) are the game, but there are also many wonderful programs that can do amazing things like track your golf score, convert currency, help you organize your kitchen more effectively, figure out how much tile you need in a room. Almost anything that needs to be done, there is a piece of software that can do it-open source. The important thing to remember is that you won't find these programs in your local software store but you may find something similar to your copyright software sample that will cost considerably more money than the finished and polished version of the software that you are able to sample free. Copyright Law Plagiarism Plagiarism Is Simply Unethical Anyone who is a writer is concerned with plagiarism. Copyright Plagiarism Laws protects copyright holders from having their works plagiarized. Many people think it is ironic that the word plagiarism derives from “kidnapper” in Latin. However, it is true. If a person uses another person’s words without permission, they have indeed stolen or kidnapped something that was owned by another and is in violation of copyright law. Plagiarism is a very bad word in the writing world. Crediting the author of the work will not keep someone immune from being in violation of copyright law. Plagiarism is plagiarism, even if the author is cited if the author did not give permission for the work to be used. One of the most common areas that copyright law plagiarism is violated is in the academic world. Many students will copy and paste the information they need for their research papers and essays straight off the Internet and turn it in to their professors. However, this type of cheating is easily detected now with special programs that professors can use. Plagiarism is unethical, not only in the writing world, but in the academic world, as well. Did you know that you could plagiarism a work but not be in violation of the copyright? Likewise, you can be in violation of a copyright and not have been plagiarizing. It is really not that hard to understand. Let’s say you are using Abraham Lincoln’s exact words in a paper and you did not cite him as the source or give him credit. Well, Lincoln’s words aren’t copyrighted because they are in the public domain. But, you did plagiarize because you tried to pass off his words as your own. Alternatively, if you use a picture in a book and you did not gain permission to use the book, you have violated copyright law because you did not source the artist and you did not get permission from the artist to use the picture. If you are in school, the best way you can get around committing plagiarism is to simply list your sources. If you use someone’s word, list it in an endnote or in a footnote. List the resource you found it in the bibliography. Another way around copyright law plagiarism violations is to take notes when you are reading. Take notes in your own words and put the resource away. Write your paper from your own words. No one wants to be singled out for plagiarism, especially a student who is concerned about their reputation at school and writers who need to keep their credibility in good standing. With today’s technological advances, it is not too hard to pinpoint plagiarized work. Even webmasters who run websites are on to the plagiarism crowd. They can run their entire sites through a special program to see if their content has been stolen and duplicated elsewhere on the Internet. If you are dealing in the written word, either academically or as a profession, it is a good idea that you only use your own words. It was probably easier to get away with plagiarism 100 years ago, but it is not that easy today. The changes are very high that if you are caught violating copyright law plagiarism laws you will be caught. Not only is it embarrassing, but it can cost you a bundle in a lawsuit. |
