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.
Important Networking Follow-Ups: How to Get Those Job Leads Calling When you leave a networking event, you may be buzzing at the prospects offered by all of those new contacts you made, but soon, the cold reality sets in. How will you be able to convert those contacts you made over a glass of wine into valuable business opportunities for you? Successful networking is all in the follow-up. If you’re looking for a job, following up is all the more crucial. Without touching base after a networking event, you become just another face in the crowd of job hunting hopefuls. The first important rule for following-up with networking contacts is to lay the foundations for the follow-up during the initial meeting. At networking events, there can be a lot of empty promises thrown around. Use that first meeting to convey the message that you haven’t gotten caught up in “networking fever” but instead that you are very serious about exploring the job opportunity that you’re discussing with your new contact. Ask the contact when would be a good time to follow-up with them, and then reiterate the information back to them at the end of your conversation: “I look forward to speaking with you Friday at 2 p.m.” If they don’t give you a specific time, then suggest one to them. This rule holds true even if your contact is giving you a lead on a job not with them but with another contact of their own. Let them know you appreciate the information by saying, “Thanks. I will plan on calling Mary on Monday afternoon at 1 p.m.” Not only will this convey your seriousness about the opportunity presented to you, but it may also get you some handy inside information, as the contact may reply, “Oh, no, Mary will be out of town until Thursday – call her then.” The next important rule to networking follow-ups is to follow up with EVERY lead a contact gives you. If a contact suggests that you call someone whom you know won’t really be able to help you in your job search, call him or her anyway. Otherwise, when your contact finds out you aren’t taking their advice, they may just decide not to give you any more the future and any business person can tell you that you never know from whom the most valuable lead will come some day. Keep the lines of communication open by giving any and all suggestions a whirl. Last but not least, do the actual following-up. Follow up with your contact exactly when you said you would, and in the exact manner you said you would (phone, email, letter, etc). If for some reason you can’t make contact at the arranged time, keep trying. If you haven’t made arrangements for a follow-up with a contact, then the rule of thumb is to follow-up with them as soon as possible after meeting them. Try to at least send an email or letter the next day saying what a pleasure it was to meet and that you look forward to talking more in the future, and then say in that note when you plan to follow-up with your contact by phone. Then, of course, stick to that new follow-up obligation. Even if the promises made by a contact while networking don’t pan out for you on the job front, don’t cross them off of your contact list. Keep them in the loop about your job search and your career goals. While they may not have been able to make if happen for you this time, you never know what they might be able to do for you in the future. Your most promising business contact may be someone you already know. Clean Up your Digital Profile and Land that Job Whether you are looking for a job after getting fired or you are looking for a job other than the one you are working at currently, many steps in that process are the same. You need to get your résumé up to date and conform to newest standards, you need to get your wardrobe together and most of all you need to be prepared to go for the interview. But did you know that in a fast paced society with all the high technology gadgets, employers and companies appreciate a good digital profile? When it is time to land a new job it is time for you to clean up your digital profile. For those of you who might not know what a digital profile is, let’s reminisce about digital profiles for just a second here. A digital profile is any and all information about you that can be found online. It can be anything from your own homepage, over articles and answers that you have posted on the Internet to videos and pictures of you. Anything that is somehow connected to you and your name and can be found through Internet search engines such as Google, Yahoo and other crawlers belongs to your digital profile or e-portfolio. Believe it or not, many employers have started to check out your digital profile online by doing a little research on the Internet and finding any information about you. If it is on the Internet it is public information and therefore not illegal. Information on the Internet does not necessarily have to be positive. What if one of your friends posted some stories or pictures/movies about you on the Internet? Employers might see that and think that you are not fir for the tasks that are asked form you by the new job and might just plain throw your nice résumé into the trash before they ever have a chance to meet you in person. Therefore before going onto your next job-hunt, clean up your digital profile. Steps you can take to clean up your e-profile are many and one of the easiest ones is a regular search with different Internet search engines about things that are related to your name. See what comes up and try to clean it up. If there are pictures or movies posted on such pages as u-tube about you, try to get friends or the owners of the page to take them down or at least take your name of the page in such a way that a search engine cannot find this information when somebody is searching for your name. A very important positive step in cleaning up your digital profile is to create your own positive statements and information on the Internet, such as online résumé, Personal web pages or a personal development plan (PDP). If the amount of positive information, academic achievements, and plans for the future are greater than any negative amount of information they can find, the light shed on you is of good nature and your chances are greater to land that job than when they only find negative information for the reasons that you never knew about a digital profile. Should you still be new to all of this and you are not quite as well versed on the Internet, there are places that can help you. Many Universities and development centers offer help and tools just for this kind of situation. Public libraries also offer you free time on the Internet as well as other resources in connection with the job-hunt and digital profiles. So before you actually send out your résumé, make sure that you checked online for any information that might harm you. |
