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.
Five Biggest Job Hunting Mistakes and How to Avoid Them Looking for a job can be a challenging experience. Between the resume writing and the interviews you can find yourself exhausted and ready to throw in the towel prematurely. Stay the course until you find the job you want. While you are on your job-hunting journey, here are five big mistakes to avoid when job hunting. Steering clear of these mistakes could make finding a job much easier. One of the biggest mistakes that people make when they are job hunting is not looking in enough places for jobs. There is a certain level of diligence you need to maintain when you are searching for a job. Look in newspapers, online and ask around. Of course, there are boundaries you should follow when looking for a job. First of all only apply and interview for jobs that you think you would take if you were offered the position. Do not apply for jobs that you are not qualified at all for or jobs that you do not have a clear understanding of. When applying for jobs, it is important to have a resume that is update and professional looking. If you are not a good resume writer, look at examples online or find a professional to do your resume for you. Employers will take one look at a messy or unprofessional resume and rule you out without ever meeting you. It is also important to be sure that you resume can be found online. There are plenty of job sites that allow users to post resumes. Some sites even allow multiple resumes to be posted. This is a great place for employers to locate your resume and contact you without you actually applying for the job. Lying on your resume can eliminate you from being a job candidate immediately. If you stretch the truth about your experience or the type of jobs you have had in the past, employers will think that you are a liar. If employers think you are a lair they will not feel confident about hiring you because you have already compromised your integrity. Tell the truth about your work and educational history. No matter what people may tell you, an honest inexperienced candidate is better than a lying experienced candidate. Have faith that you will be able to prove your worthiness for the position you are applying for without making up half-truths. Be sure that your contact information is correct and that you respond when you are contacted. No matter how busy you are, you need to check your e-mail and phone messages on a regular basis. If you do not respond to a call about a job this is a sign that you do not need employment that badly. Employers will move on to the next candidate if you are slow getting back to them. Candidates that are not prepared for their interviews are typically eliminated from the search before the interview is over. If you are late for an interview you have a big huge mark against you as soon as you walk in the door. Not being dressed in professional attire also will leave the interview with a very bad impression of you before you even speak. If you show up without a pen or copies of your resume you look like you are unfamiliar with the interview process. This, in turn, makes it quite possible that you are unfamiliar with other work place procedures. A good job hunt can land you the job of your dreams. When you are settled into your new job you will be thankful that you took the time to search for a job the right way. Finishing a Masterpiece and Getting it on the Shelves (how to get a book published) Writing a book is a monumental task in itself. The process is long, drawn out and grueling. Even if you thoroughly enjoy writing and writing on the same subject for an extended period of time, you will no doubt be exhausted by the writing of a book. Getting that book published, however, will take even more time and effort than producing the thing in the first place. Are you thinking about writing a book? Have you already written one and now are just wondering how to get a book published? If you are, read on. Here are a few tips on how to get from the starting line to triumphantly crossing the finish line. Writing that Book When starting out writing your book, before you are ready to consider how to get a book published, you may already feel daunted. To write a successful book you need to start out with some original thought. You probably have plenty of originality, but you may have trouble getting your ideas into a coherent flow of information that will be digestible by the general public. The first step is to create a book skeleton. You need to organize your thoughts into a progression of chapters. If your book will be non-fiction, start with a table of contents. Write chapter headings and sub-headings. You will automatically know that you’ll need an introductory chapter, but you should probably leave the content of your introduction for the last step. Organize your chapters so that they build upon one another. The more headings that you can brainstorm to begin with, the easier it will be to fill in your book with a series of short articles that flow into one another. If your writing will be fiction, you will need more of a storyboard. You will need to create cause and effect as well as character sketches. To make your story coherent your characters will need events to react to. Their reactions should become predictable as your readers get into the story. You may need to create some situations for your characters just for the purpose of introducing their traits to the reader. These are very general guidelines about how to begin constructing your book. The actual process will be much more involved as you move closer to finding out how to get a book published. Even after you are finished with the bulk of the content, your goal is still a ways off into the future. Getting to Print The next step in how to get a book published is finding a publisher. There are resources at your local library that will let you know who will be the best candidate for publishing the kind of writing that you do. After a series of queries and correspondence with the potential publishers you may get an invitation to send your manuscript. Then the work begins. A publisher is very experienced in finding books that are marketable. He knows what it will take to get your book to sell. Don’t be offended when his editors tears your writing apart. If they are doing that, you can enjoy the fact that you are on the road to a published book. Expect to enter into a close relationship of compromise and change with the editor as you rework and rework what you have already so painstakingly written. When you are finished you will have a readable and clean and correct manuscript ready for print. The road to getting a book published is a long one, but well worth the effort. Trust yourself, and trust the publisher to create a beautiful masterpiece. Don’t be discouraged if several publishers are not interested in your book. You may have to just keep the first few for yourself, and then again, they may eventually get accepted. Good luck and enjoy the process. |
