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.
Explaining How Credit Scores are Used in the Hiring Process You might be wondering why credit scores are used in hiring processes. While you may have never heard about it, it is actually a more common practice than you might think. Companies and institutions such as banks, universities, retail stores, financial institutions across the United States use credit scores to determine whether an applicant is good for the open position or not. Even though you might think that this is illegal, it is not. In general, it is a legal undertaking for companies to look at your credit score. This is yet another reason why you should make sure that your credit scores are good and up to date. So why would they be using your credit information in a hiring process? For some of these companies, employees will be exposed to a lot of money and have a financially responsible position. Your credit information can actually help them determine whether you are a financially responsible person or not. Companies think that if you cannot handle your own money, why you would be qualified to handle their money? On the one side, if you think about it, it is a very valid thought. On the other side, the credit history will not tell the company how you might have gotten all the debt. What if one of your family members is really badly sick or a similar situation? In this case, you have not been irresponsible with your money, but you saved a family members life. You might have been willing to take on all this debt and then work from there. Sometimes numbers are just not an accurate representation of your life. Companies that do use your credit are not only determining whether you can handle money, in some instances they use it as an indicator for your character. It will tell them if you are responsible with your money and finances you are a responsible person. A person that will not be tempted by money or certain situations in a workplace is a person they can securely trust with their funds, their tasks or their great projects. One thing is for sure, the company needs to let you know that they are going to check your credit history in their hiring process and they also need to let you know what they are checking for. The criteria they are looking is the criteria they have to tell you about before you give them the permission. Unless they tell you and have a signature of permission from you, they are not allowed to check and use your credit history. If they miss these above mentioned steps, you do have a case in you hands that you can bring to the court. In some instances, some of the people that were not told about the credit check and have been denied have had a good case in their hands. But as with so many things in life in the United States it pays off to have a good credit history and such a check will not ruin your career moves. Check your credit history every year since once a year the big credit companies do have to give you a free credit report. In the case that you find any wrong or dubious items on your account go ahead and dispute them. Oftentimes companies might just have put a claim against your account that is not really caused by you. Why do companies do that? Money has caused many bad things in the world and a company that wants their money back is going to run after any lead they have. Therefore disputing your case and putting your credit score back to normal can be an essential part in your application and hiring process with some companies.
