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.
Three Important Tips to Land Better Job Prospects If you are not satisfied with your current job or the job prospects that you are running across, it is time to revise your search. Use these three tips to help find the type of job prospects you are looking for. First of all, before you start your job search, figure out exactly what it is that you are looking for. Going out into the world and searching for any type of job is the perfect way to end up with an array of job prospects you are unsatisfied with. Think about the reasons why you are ready to leave your current job. Consider what things you are looking for in a career that your current job is not giving you. Are you looking for make more money? If so, only apply for jobs that will increase your income. Are you tired of working long hours and weekends? Then do not apply for jobs that will keep you at the office after hours and during family time on the weekends. By defining what exactly it is that you want in a job, you will be able to weed out the jobs you do not want. Once you are able to concentrate on the select few that have the qualities you are looking for, you will be able to put froth the effort necessary to get those jobs. Another thing that many people do when they are looking for a job is underestimating their own skills. You do not want to apply for jobs that you have absolutely no skills or training for unless they offer training, of course, but you can apply for jobs that you have some of the skills to do. For instance, if you are apply for an office job where that you need to be able to maintain the company website and you are familiar with the components of designing and maintaining a website, but have not done it on a regular basis, apply. On your resume explain that you have a working knowledge of html and other website tools. That way the employer will understand that you are not an expert at the task but you are capable of beginning, and with some help, finishing the task. Never misrepresent your skills on a resume. Instead, be honest and place emphasis on the skills that you do have. Apply for jobs that you have some of the skills for only. If you get an interview, be ready to impress the interviewer by being totally prepared. Speak confidently and make eye contact. Confidence can take you a long way when it comes to the job hunt. Shoot for the stars! If you want better job prospects you will need to believe that you deserve a better job. That means you will need to have some faith in yourself and be willing to apply for higher-level jobs. The only way you are going to get better job prospects is if you apply for the better jobs. Do not be intimidated by job descriptions. If you read a list of responsibilities and you cannot perform all of them yet, apply for the job. There is a good chance that you will be asked if you can perform the specific tasks of the job when you get an interview. This is the time to explain what tasks you are capable of performing. Better job prospects are highly attainable. You just have to clearly define what it is you want from a job and believe that you deserve and will get that type of job. Believe in yourself and you are halfway there. Some Info on Those “Get Paid To” Sites Where You Can Get Free Stuff Anyone who has spent even five minutes online is aware that there are many websites that offer free stuff, and many people cash in on hundreds of dollars of free stuff every single month. But what about taking that one step further? What if you could not only get some free stuff, but also actually get paid to get free things? It sounds impossible but actually you can make a profit on getting free things online. The catch is that you have to devote a little bit of time and effort to finding these deals and completing them, but many people find that getting paid to get free things is well worth a little time investment. One of the top places to cash in for free stuff is so called “get paid to” websites. These “get paid to” websites usually act as clearinghouses for all kinds of internet offers that give users the chance to make some quick cash by completing some tasks. Most of the time, the tasks you have to complete on these “get paid to” websites involve filling out some kind of survey or submitting your contact information to a company. When you visit one of these websites, you can often click through offer after offer and complete them in your own time, racking up the cash along the way. But sure, filling out surveys is a way to get paid for doing something very easy, but what about getting paid to get free stuff? These offers also appear on these websites. Most often, you will get a free meal at a local restaurant and then get paid for submitting a report about your experience there. This kind of “mystery shopper” deal is also in place at many big chain stores, where you may be given a gift card for a small amount to go into the store, buy something and report back about your experience. Companies use these services to test their customer service in stores and figure out what they could be doing better. So, not only will you get a free meal or a free item at a store, you’ll get paid for telling the company if you were treated well by the staff – not a bad gig if you can get it! The way to get one of the deals is to keep a close eye on the “get paid to” websites. There are many of these websites out there, so the best way to figure out which ones are worth your time is to look for ones that have deals on offer from big name companies that you know. Most of the times, a major company will work with one website exclusively, so you getting in with the website that has the biggest number of big name companies mean you will have access to the most valuable “get paid to” deals on offer. Is there a catch to all of this free stuff? Well, there can be, but you can mitigate the hassle to some extent. The biggest problem with free stuff online is that you have to hand over your email address to a company who is sure to both solicit you in the future and sell your email address to other companies who will also start soliciting you by email. Cut the hassle by setting up a separate email address just for these purposes, so that your primary email address does not struggle under the weight of the spam. Also, never give out your phone number – you can use a phony one with a 555 exchange or set up an online number that you use only for freebies. Managed properly, you can really get paid to get free stuff with a minimum amount of hassle. |
