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.
Turning your Eye to Government, Nonprofit or Small Business for you Next Job The type of business you work for can effect your job satisfaction. Your personality type may also work out better at certain types of businesses. Research different business types before going on your job search. Working for a small business or a non-profit definitely has its pros and cons. First of all, getting hired at a small business can be much easier than landing a position than at a corporation. Typically you will only have to go through one person to get the job. Usually the small business owner conducts the interview. This can be a good thing because the business owner may be willing to overlook a lack of experience or extenuating circumstances concerning your work history. Nonprofit jobs are often easier to get if you are passionate about the cause. The person that is doing the hiring is generally passionate about the cause that the nonprofit is working to assist. If they pick up on passion about the cause from you, typically you will get the job. However, that passion is necessary because they pay may not be very much. Working for a smaller company also opens up more opportunities for promotions. With fewer employees and contact with the owner, you may be able to move up in the company faster. You will be able to pick up on skills in less time than at large corporations, which often have many hoops for one to jump through before training for a new position. There may be a smaller window of time to pick up on new skills because of the limited amount of time that can be put towards training. Nonprofits may not have as many opportunities for promotions and job stability may be questionable. If the donations stop coming in or whoever funds the nonprofit decides not to fund it anymore, you could be out of a job. This is a very real concern with a nonprofit job. There are some drawbacks to working at smaller businesses. Sometimes, the staff at smaller businesses have been in place for years. New, younger employees may not be viewed favorably. This could affect working relationships with co-workers. Smaller companies also mean smaller paychecks. Independent businesses are not able to generate large paychecks. This could make staying at a small business undesirable. However, the personal interaction between you and your boss could be encouragement to stick it out with a small business. Or the opposite could be true. Government jobs can be beneficial to have for a number of reasons. First of all, government jobs offer good salaries and great benefits. You will have all government holidays off and you will be working in a position that is necessary to the maintenance of the government. That means that you probably won’t have to worry about being displaced. Although, remember that if the government runs into tough times, layoffs are possible. Government jobs are usually normal business hours but not always. There are some positions that will have hours that extend a little bit beyond regular business hours but for the most part, you will be able to enjoy your life by taking advantage of vacation time. Sick days will also be available at government jobs. Some of the drawbacks of government jobs are that you may have to deal with a large amount of on the job stress. You may be responsible for processing hundreds, maybe even thousands of cases and one mistake could be very tragic for an individual. Depending on what your position is, you may be instrumental in handling paper work from a huge amount of people. Five Positive Actions You Should Do After a Lay-off Lay-offs are hard for most people and are essentially difficult to cope with if you were and excellent worker and outstanding employee. Sometimes lay-offs are general cuts such as the closing of a whole department. It often times hits good employees that the company otherwise would have never gotten fired. So what do you need to do after you get laid off? Here are five positive steps you should take after you have been laid-off. The first and probably most important step is coping with the situation. Get your feelings straightened out. Of course you are upset and plain dumbstruck by what happened, but if you are not able to get this sorted out with yourself, the company is not going to take you back. Then you won’t even have a chance of finding another job. In some cases, if it was not very clear why you have been fired, it helps to talk to coworkers, and maybe the human resource person to just find out that it was not you or any of your doings that got you laid-off. Within this step falls also the realization that the job market currently is a tough one and that you might have to make some budget adjustments first off all. Do not be picky about what kind of jobs you want to choose. Sometimes, this means a new beginning, some job you might like much better than your old one, and you just do not know it yet. After you have been able to work through the situation and are ready for the job hunt, get your résumé out. If you have not been looking for a job in a while it might be dusty and not be up to date. Add your last job to the list; add your role and responsibilities to your list and maybe you even have to adapt your résumé to a more current style. Résumés and cover letters are your way into a job and the first impression that a new employer gets from you. When you are finished getting your résumé up to date, apply to as many jobs as there are. As a third step, make yourself clear that the job market is difficult and finding a new job might mean to apply for something that you might have not really wanted to do, maybe because you did study it, but you never really liked in the university classes? Well, it is worth applying for. The sooner you get another job, the better of you are. Face it, if you really do not like the work you can find another job after a year or two. After a lay-off it is very important to get back into the working world as fast as you can. To make your job search even more successful, as a fourth positive step after a lay-off, you also need to network. Talk to friends, other companies’ bosses you know, and anybody you have ever met that might have a job available for you. Besides networking, you can also always try to do some cold calling, writing letters to businesses that are not having a newspaper add out. There is always the possibility that they are looking for somebody. As a fifth positive action after you are laid-off there is always college. Taking classes that will refresh your topic and specialty you are working in can make a good bullet on your résumé. If the job market is quite tough, why not go back and finish that degree or add another maybe a graduate degree. This always is better on your résumé than plain being out of work. |
