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.
Bring These Important Tips to the Table in a Telecommuting Argument Are you tired of the sound of the alarm clock every morning? Are you equally tired of trying to figure out what to wear every day (ladies) and fighting the rush hour traffic to get to the office in time? How about spending almost your entire paycheck on gas to put in your car to get you to work? There is a way around all of this of course – telecommuting. When you telecommute to work, you can catch a little bit of extra shut eye and head to work in your pajamas, without even getting in the shower. But aside from the convenience factor, there can be a lot of other good reasons why telecommuting makes sense. If you can put together a convincing enough argument for your employer, you may find yourself going to work in your bedroom slippers before you know it. The first thing you have to keep in mind about your telecommuting argument is that you have to make sure you have plenty of evidence that telecommuting will be beneficial to your employer, not just you. Sure, you would love to be able to see the kids off to school in the morning and take your coffee break in front of your favorite soap operas, but your boss doesn’t care about all of that. Though you don’t have to hide the fact that telecommuting will obviously have its privileges for you from your boss, remember to include plenty of ammunition for benefits to the company as well. What can you bring to the table in terms of telecommuting advantages for your boss? Point your boss to a growing amount of research on the internet that shows that big companies have seen big increases in productivity when they started letting people telecommute and work from the comfort of their homes. Everyone knows that a rested and stress free employee is a productive one, and offices can be filled with more distractions than your home (gossiping employees, phones always ringing). Some companies have seen increases in productivity of over 50%, something that is sure to get your boss’s attention. You can also point out to your boss that absenteeism takes a nosedive when people telecommute. No need to take a fake sick day to get out of going to office when you work from home, and even when people are under the weather, when the office is in the next room, they still tend to get a few things done on a day that would have been a total write off otherwise. Another selling point for your boss may be that everyone else is already doing it. More than half of the companies in the US have employees that telecommute, with great results. Your boss won’t want to let the company fall behind – and your boss will know that offering what other companies have is important for employee retention. Make sure your boss knows that what you are asking for is not out of the ordinary in any way. Beyond the selling points for your boss, you can be specific about a few benefits to you. Bosses know that gas is major issue for employees – telecommuting is a way they can let you cut back on that big expense, without feeling under pressure to respond with wage hikes. If you have customers that live near your house, let your boss know it will be easier to meet them face-to-face if you work from home. Last but not least, let your boss know that you believe you can deliver more to the company from the comfort of your home - more work for the same pay is always music to an employer’s ears. Let your Resume Speak Volumes for that Next Big Job Before you even get through the door of any job interview, there is already one document that has done the talking for you – your resume. A good resume can mean the difference between getting the call of the interview and waiting by phone, and a well written, thoughtful resume can make you stand out over and above other applications with similar skills and work experience. Let your resume give you the edge on that next big job by following a few simple tips. When you sit down to write your resume, you need to plan it out before you start typing. There are two main formats for a resume: the chronological format, in which you simply list your job history, starting with your most recent or current job and moving backwards, and the functional format, in which you highlight your skills and experience rather than specific jobs and specific employers. The chronological format is definitely the most common, and many employers prefer this kind of resume, but choose the format this is going to show off your skills in the best light. If your work history is a choppy and a chronological format resume would only draw attention to that, use the functional format. The key is to choose the format that will give you the best chance of getting noticed for the job and to stick with the format throughout your resume. No matter which resume format you choose to use, the top of your resume should always include your name, contact information and work objectives. Name and contact information is pretty straight forward, although experts do recommend that if you have a “gender neutral” name that you include a helpful “Mr.” or “Ms” to clear up any confusion. Your work objectives should be your career goals. For instance, if you want to manage a small team of sales people, then say that, so your potential employers know that you are moving in a certain direction with your career and not simply apply for jobs willy-nilly. After your work objective comes your work experience. List your jobs in reverse chronological order. Instead of simply creating a bullet pointed list your work related tasks, look for a way to frame all of your responsibilities so that they sound like you showed leadership and problem solving capabilities. For instance, if you were in charge of keeping the expensive accounts in order, say that you were in charge of troubleshooting monthly expense account records, saving the company hundreds of dollars every month. If you have a few blips in your work history, be clear about what you were doing in the downtime. If you were raising children, traveling, or in school, say that you were. If you weren’t really doing anything, put as positive a spin on things as you can without lying. Never leave gaps in your work history unaddressed on your resume. After your work history, it is time to list your education credentials. If you didn’t finish a degree, say how much college work you completed and highlight any coursework relevant to the job. If your college degree or post grad work is in progress, say when you expect to be finished. This is another place where gaps matter. If there is a gap in your education history, again say what you were doing in that time, referring back to your work history where appropriate. You can overcome these gaps as long as you don’t pretend that they don’t exist. Round out your resume by listing any awards and professional memberships you may hold. Don’t get into your hobbies unless they are specifically related to the position for which you are applying. Personal details like religion and race have no place on your resume and you are not required to disclose your age. Instead, let your experience do the talking. |
