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.
Copyright Law Act The Copyright Law Act of 1976 The Copyright Law Act of 1976 is the basis of the United States copyright laws. The Copyright Law Act states the rights of copyright owners, the doctrine of the fair use copyright laws and it changed the term life of copyrights. Before the Copyright Law Act the law had not been revised since 1909. It was necessary that the copyright laws be revised to take into account technological strides that were being made in radio, sound recordings, motions pictures and more. The Copyright Law Act of 1976 preempted all previous laws that were on the books in the United States, including the Copyright Act of 1909. The Copyright Law Act of 1976 defines “works of authorship” to include all of the following: * Musical works * Literary works * Dramatic works * Pictorial, sculptural and graphics * Motion Pictures and Audiovisuals * Sound Recordings * Choreographic Works and Pantomimes * An eighth work which falls under “architectural works” was later added in 1990. What is unique about the United States copyright law is that it is automatic. Once someone has an idea and produces it in tangible form, the creator is the copyright holder and has the authority to enforce his exclusivity to it. In other words, the person is the owner of the creation. It is not necessary that a person register their work. However, it is recommended and it can serve as evidence if someone ever violates a copyright. It is interesting to note that when an employer hires an employee to produce a work that the copyright is given to the employer. Violations of US Copyright Law are generally enforced in a civil court setting. However, there could also be criminal sanctions brought against someone who violates US copyright law. Someone that is in serious violation of US Copyright Law such as counterfeiting can find themselves on the inside of prison looking out. People need to understand that the copyright symbol is not a requirement. Someone may have a copyright, yet their work may not have a copyright notice or symbol. US Copyright Law covers a wide range of things that are derived from artistic expression, intellectual or creative work. This includes things such as literary works, music, drawings, photographs, software, movies, choreographic works such as ballets and plays, poems, paintings and more. The law covers the form of expression, not the concept, facts or the actual idea of the work. This means that someone can use another person’s idea or concept and produce their own take on it. However, copying another person’s work is a violation. It should be noted that some things may not be copyrighted but they may be protected by a patent or trademark. Individuals who have a copyright on a particular piece of work can do with it what they will. They may choose to copy it and sell it. They may display their work or perform it in public and charge admission, or they can assign or sell the work to someone else. Individuals who have a copyright can also choose to do nothing with their work, if that is their desire. However, if someone comes along and takes the work and tries to use it in some way, that person is still in violation of the owner’s copyright. The Copyright Law Act covers published and unpublished work. Can Job Sharing Boost your Employee Profile? Job sharing is one of the newer occurring work arrangements on the job market. It means that two or more people share one full time position. Most often it is two people that work part time on the same position. This kind of work sharing is a great invention for all parents that want to spend more time with their children or for people that are just not made for a full time job. Job sharing is a flexible job option that shares one person’s responsibilities between two people. So, can job sharing boost your employee profile? Yes, of course is the answer to that. The reasons why job sharing boosts your employee profile are widely spread. Job sharing can bring benefits not only to employees but also to employers and companies. Start by looking at the aspect of sharing your work. If you are sharing a full time position load with another person, pressure is less on you. You still have the same deadline, but the pressure is shared and you can work more efficiently on your work assignments. Less stress makes for a happier more relaxed employee that can tackle the work given to him or her easily. This makes the employee a more balanced person. The possibility to stay at home while still having a chance to be part of a company can further your career and keep your skills up to date and this makes for a well balanced worker. Another reason why job sharing might boost your employee profile is that two people working part time actually can get more work done as one full time employee. Why is that? Well, that is very easy. While the full time employee is very tired in the mid afternoon from his already long day, the person coming in for the second half of the day has had time to relax all morning long and therefore can start with new end fresh energy and thoughts on the shared work. Should the position not be shared in half days, but in each taking a few full days, then the people sharing the position are still more relaxed and motivated. They are able to be with their family, able to rest and regenerate or have fun with some of their favorite hobbies. Psychologists and researchers have long praised the effect that a fun family filled time and enough time to be you and relax can boost your employees’ work input as well as their efficiency. In countries where employees have fewer hours per week and more vacation days a year, the work output per person is in general higher and employees are happy and motivated and stay with their company for long periods of time, if not all the way up to retirement. Additionally, if you have a good amount of time off from work, you are most likely a very motivated and happy employee and your boss and fellow employees will see you as a positive person to be around at the work place. Being a leader and motivator is all that a boss can hope for and therefore, sharing the position can immensely boost your profile. For employers, there is also the consideration of your benefits. Some companies might not pay benefits to part time employees and two part time positions will save you money. In this case, your profile is simply boosted by the fact that your employer saves money. Although in some companies, there are benefits for part-time employees and those can be based on different facts, such as hours worked, full-time benefits and more. Before considering sharing your job and entering the world of part-time employment, make sure that this is exactly what you are looking for in a job. Once you are sharing your position, there might not be a way back to full time, at least not within your own company. |
