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.
Networking Know-How: How to Get Through to the Busiest of People When you are job hunting, sometimes the most frustrating part is just getting your foot through the door to let the right people know that you are out there and available for work. Companies can be like members-only clubs; they tend to be a little distrustful of cold callers and most executives advise their assistants to run interference for them on the phone so they do not get stuck having a protracted conversation with someone they just aren’t interested in doing business with. The thing is that to get an interview, these people can be the very same people you need to talk to. How do you get these busy people to clear some time off in their busy schedule to speak to you? First things first – you have to get the right attitude. If you want busy people to make time to talk to you, you have to present yourself in a way that makes them feel like you are worth the time investment. The trick here is that you have to do this by phone, and often, you have to first convince an operator or personal assistant that your call is one worth putting through to the boss. Your phone etiquette and vocal confidence will be the key here. Consider you basic phone manners first. Instead of launching right into what you want, respond to the greeting of the person who answers the phone with a hello of your own. Animate your voice and always remember that simply saying “please” and “thank you” can go a long way. Be the kind of caller that you would want to talk to if your job was answering the phone all day. People will respond to your positive attitude with a positive attitude of their own. Next, consider your confidence level on the phone. Do you tend to get tongue-tied and stumble over your words? That kind of delivery from you will set all the warning bells ringing on the other end of the phone, and you will find the person with whom you wish to speak always “out of the office.” Instead, work on sounding like you are confident that it is a forgone conclusion that you will get to speak that busy person you want to talk to. Be confident that what you have to say is something that is worth hearing. It may help to write out a framework of what you will say and practice a few times so you sound relaxed and composed when you make that call. Once your attitude is right to make the call, you can then employ a few tricks of the trade for getting through to those busy people. Instead of giving away too much up front, start your call by asking if the person with whom you need to speak is in. If the answer is yes, then you can remove on potential “excuse” for not putting your call through. If your call can’t be taken at that time, skip the message. Let the PA or operator know that you will call back again. That way you have a legitimate reason to keep calling. Of course, you might have to keep calling and calling, and that assistant might start knowing the sound of your voice. If you keep speaking to the same person, it’s time to open up with some person details. Let them know your name, why you’re calling, and if someone referred you, who that person is. Developing that personal relationship can help you get your call through to the boss. Last but not least, don’t give up. Busy people are, well, busy, and not necessarily avoiding your call. Persistence pays off, so keep on calling until you get through. Working on Your Own Time: It’s What Freelancing is About (freelance jobs) Do you have a busy life? Do you wish that you could schedule your work around the rest of your priorities? You work to make money so that you can live. You have no choice but to pay for housing and food and other life necessities. Because you need the money, work tends to creep up to the top of the priority list. Other things are more important though. Freelance jobs allow you to put work where it belongs on the list of priorities. You can play with your kids when they’re home, enjoy doing the things you enjoy outdoors while it’s daytime and spend your Sunday mornings at church instead of behind a counter. The work still needs to get done, but you can do it when you have time instead of from nine to five, Monday through Friday or worse, whenever you’re put on the schedule. Kinds of Freelance Jobs Do you have the appropriate skills and abilities to work at freelance jobs? There are many, many different kinds available. Those with professional degrees can consult. While the jobs that result from extensive education generally lead to many hours working for a good salary, your education can lead you in another direction. If you can manage to find the clients, you can work by appointment only, guiding those who do not have the experience or education that you have. If you are not a professional, you may still have the appropriate talents that will get you into freelance jobs. Writing is a very popular freelance opportunity. You live in a world that relies on the written word. You do not go through a single day without reading a considerable amount of text. Someone needs to do all of that writing, and much of it is hired out to freelancers. Actually, any skill that you possess may be suited to freelance work. Check out a few job boards and find out who’s hiring. Tips of the Trade Freelance jobs are out there, but so is the competition. To get yourself to the top of the hiring list, there are a few things you can do. First, use any experience you have to your advantage. Even if a previous job was short term or didn’t seem significant to you, you gained experience there. Let the employers know about everything you can do. Another thing you must do as a freelancer is to be very consistent and organized. An employer will be much more likely to rehire you if you turn out a good product. Everything you turn in should be clear and professional. Always meet deadlines. While most of the freelance jobs are extremely flexible, allowing you to work at your convenience, there are still deadlines. The work needs to be finished when the employer asks for it. Most of the qualities that will get you more freelance jobs only require common sense and a good work ethic. Living on Sparse Paychecks One downside of freelance jobs is that they are not necessarily consistent. Especially if you jump from one job to another, working for different companies, you will not have any guarantee about how much you will get paid each month. The flexibility may or may not be worth the uncertainty of freelancing to you. If you can manage to save effectively, the distance between paychecks won’t matter. If you do get frustrated about always wondering where the next paycheck is coming from, just remind yourself that the trade off is getting to enjoy more precious time not tied to a desk. There are definitely pros and cons when it comes to freelancing. You just need to decide how important it is to you to prioritize your life around what really matters to you. |
