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.
Ghost Writer: Who Uses Them and Why (ghost writer) A ghost writer is someone who is hired to write for another person under their name. In most cases ghostwriters do the work while the hiring person gets the credit. The use of a ghost writer is huge business. People in virtually every aspect of life could use a ghost writer. A ghost writer will need the ability to become the person they are writing for. The writer has to be able to use their mannerisms, their words, and their way of speaking. The writing must read like they are coming from the person themselves. Being a ghost writer means that you give absolutely all rights to the credited author. You will need to decide if it is worth it for someone else to take credit for your work. There will be confidentiality clauses in your ghost writing contracts. They will state something to the effect of legal action will be against you if the writing is reproduced by you in any way shape or form. There are many reasons why a person would use a ghost writer. Celebrities and public figures use ghost writers to write their biographies and memoirs. Ghost writers are hired to make celebrities sound as interesting and compelling as possible. Their purpose is to pen the stories into best selling books. Motivational speakers may use ghost writers to write self help books. Just because they are great speakers does not mean they can pen the words on paper. Or they just may simply not have the time. There are many types of ghost writing opportunities available. Non fiction writing would be your biographies, autobiographies, how to books, and memoirs. A ghost writer’s role in non fiction could range from the very minimal to the most complex. They may be given an almost complete manuscript and asked to add some finishing touches. Or they may have to start at the bottom collecting research and following the project through until publication. Accomplished fiction writers may use ghost writers to carry on a series of books after the author has passed or to carry out the series while they work on new ventures. The Author may have an established pen name that they use a ghost writer for while they write under the real name. Ghost writers are often used for scripts and screen plays. They are hired to finish and polish the writings of the authors. High school and college students will hire ghost writers to write their entrance essays, thesis, and term papers. Although this may seem unethical, it is legal. The writing and selling of the paper is perfectly legal. It is when the student turns the paper in as his or her own writing that it turns into an illegal action. The political venue for ghost writers is to correspond to the letters that they receive. Official will review the letters before being sent. A political speech writer is often considered a ghost writer. But others will argue this since it is public knowledge that political officials do not write their own speeches. In order to succeed as a ghost writer you must have excellent writing skills and often be able to take on the personality of the credited author. You must also be a great sales person in order to sell your service and be able to prove that you are the best possible choice for them to use you in their endeavors. Making the decision if ghost writing is right for you may be a difficult one. It is often hard for writers to give up all rights to their work. Software Copyright Laws Software Copyright Laws Fail to Provide Adequate Protection Software copyright laws are among the most difficult to enforce among the masses. Many companies and corporations are also well known for overlooking these laws, which were designed to protect the makes of software from not earning their worth. Perhaps one of the biggest hitches leading so many software businesses to go out of business is the fact that they have a great deal of difficulty actually enforcing the software copyright laws that are in place and getting the money that is owed them according to the agreements that have been made with those on the using end of the software. Software developers, particularly in the corporate world design software that makes other companies run more efficiently. The software allows these companies to save millions of dollars each year. Software copyright laws protect the interests of the software developers that create these massive programs. These programs are often designed specifically for that one company and are very expensive. The agreement often consists of a certain number of users with the company purchasing more licenses or copies of the software during expansions or paying some sort of royalties for the use of the software. The purchasing companies agree to this and then more often than not fail to honor that agreement. The agreement is what allows this company to use that software, this agreement is what allows that permission. When companies aren't living up to their end of this agreement they are not only guilty of breaching that agreement but also of breaking software copyright laws. The trouble always lies in proving that they are not honoring the contract and the extent and duration of the breach. Some of the ways that companies will argue in defense of them not paying the royalties, additional fees, purchasing additional software, etc. is that they upgraded computers and reused the old software (they did actually purchase the rights to use the original software and by doing so feel that they have broken no software copyright laws) the problem lies in the fact that adding ten new computers and placing the software on those should mean that you remove it from or get rid of 10 old computers. This is rarely how it works. So now they've basically stolen ten copies of software that can be well worth hundreds of thousands of dollars. Multiply this by 10, 20, or 100 companies trying this or worse each year and the offending companies are costing software developers millions of dollars in profits. This is when software copyright laws are not as far reaching in their scope as they really need to be. Software copyright laws exist to protect the software companies from this type of abuse and misuse, however, the hands of the companies are almost unilaterally tied when it comes to proving that software copyright laws have been broken in court. There are always exceptions to every rule. In this case big business software developers that abuse the software copyright laws to the point of breaking make the exceptions rather than miserly consumers that do not wish to pay for the products they are consuming. The big boys are able to do this by offering licenses for their software and claiming that these laws do not apply to their situation because they are not actually selling the software only 'renting' out permission for people or companies to 'use' that software. The true irony is that these practices began as a response to the corporate irresponsibility mentioned above. It's amazing that the very software copyright laws that were created to protect these companies can't protect their consumers from the greed of the developing companies. |
