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.
The Business of Self-Publishing (self publishing) Self-publishing has become a common practice for many writers. Writers’ reasons for self-publishing are varied, but it is commonly known that many writers want the accolades of having published work, no matter who publishes it. The freedom and business aspects of publishing work independently are desirable to many writers. A self-published writer is one who is in control of every aspect of their published work. The term self-publishing is defined as the publishing of books and other media by the authors of those works, instead of being established by third-party publishers. The advancement of technology has caused an increase in the self-publishers world, but it still only represents a small percentage of the publishing industry in terms of sales. The proliferation of media channels and web logging has contributed to the increase in self-publishers. The business of publishing books and other media independently is one that is unique and different from any other business. The most distinguishing characteristic of self-publishing is the absence of a traditional publisher. The author of the content takes on the role of the traditional publisher. The author is given editorial control of the content, arranging for printing, marketing the material, and distributing the material to consumers and retailers. The published books may be printed on demand with no inventory, which places a large amount of financial risk for the venue on the author’s shoulders. Many self-published authors end up subsidizing their work rather than making money from it. Digital printing technology has made it possible for the self-publishing concept to become mainstream in digital photo book printing. Self-publishers are able to get individually printed photo books from firms like Apple’s iPhoto, FotoInsight, Snapfish, and Printing-1. The motives for publishing work independently are varied, and there are numerous reasons for choosing to self-publish. One common reason is that the work of the author is not of interest to the commercial publisher, and otherwise not marketable. Some other common reasons for self publishing include an author’s preference to retain complete editorial control over content. Many writers are unwilling to compromise when it comes to the editing of their work, and some prefer to have their work presented “as is.” Writers may also be denied publication because they are unknown and don’t have a substantial resume. Self-publishing may also be an alternative for writers who have written material on a popular topic but that is only of interest in a small geographic area. Topics that address an obscure topic in which few people are interested may also be denied publication by commercial publishers. Writers of controversial works may also choose to self-publish, as many traditional publishers refuse to work with controversial writings. There are also some authors choose self-publishing because they want a larger percentage return from retail sales. Whatever the reason for self-publishing, authors should know that there is extensive work required in publishing a book alone. Publishing alone involves a long list of tasks, which include prepublication and publication. Prepublication includes editing or obtaining editing for the manuscript, proofreading, establishing yourself as a legal retail business, and obtaining an ISBN “Cataloging in Publication” number. The publication process involves formatting the manuscript, providing front matter and back matter, and providing cover art for the front and back covers and the spine of the book. Self-publishers must also obtain printing quotes, determine how the manuscript will be delivered to the printer, and pay for printing and delivery of finished books. Self-publishing is a business that many writers prefer to avoid, but for others it may be the only way to have the work printed and available to the public. Patent and copyright law Understanding Patent and Copyright Law Patent and copyright law gives the inventor the exclusive rights to the invention. No one else can produce the invention for a set period of time under patent and copyright law. Patent and copyright law is set up to protect inventors. The law on patents can be found in the United States Constitution, Article 1, Section 8 and in Title 35 of the United States Code. The agency that is in charge of patent laws is a Federal Agency known as the Patent and Trademark Office. Anyone who applies for a patent will have their application reviewed by an examiner. The examiner will decide if a patent should be granted to the inventor. Individuals who have their patent application turned down can appeal it to the Patents Office Board of Appeals. Just because someone has a patent does not mean that they have the right to use, make or sell the invention. For instance, if a drug company comes up with a new drug, they can get a patent on it. However, it would not be available to be sold to the general public until the drug becomes approved by other regulatory bodies. Likewise, someone may invent an improvement to an existing product, yet they will not be allowed to produce or sell the item until they obtain a license to do so from the owner of the original patent holder. For someone to receive a patent, as stated, they must fill out an application on their invention. The application will entail the details of the invention and how it is made. In addition, the person applying for a patent must make claims that point to what the applicant deems or regards as his or her invention. A patent may have many claims with it. The claims protect the patent owner and notify the public exactly what the individual has patented or owns. If someone infringes upon patent and copyright law, it is usually enforced in a civil court setting. The owner of the patent will generally bring a civil lawsuit against the person who has infringed upon their patent and ask for monetary compensation. In addition, the patent owner can seek an injunction which would prohibit the violator from continuing to engage in any acts that would infringe upon their patent in the future. Many patent owners will make licensing agreements (or contracts) with others. These agreements allow another person or company to use someone’s patented invention in return for royalties. In addition, some patent holders who are competitors may agree to license their patents to each other to expand both of their profits. Most everything we use in our day to day life was invented by someone. That person had to seek out a patent for their invention. Patent and copyright law protects inventors from having their ideas and inventions stolen out from under them. This makes the playing field more level for individuals. Without these laws, the marketplace would be out of control and the small guy would probably be eaten alive by big business |
