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.

Evaluating your Free Offers of Stuff Getting free stuff can be a lot of fun, and for many people, the hunt for freebies is as fun as actually enjoying the free products themselves. There is a dark side to freebie offers, however. Many scam artists have come to realize that pretending to offer free things is a great way to trick people into handing over sensitive information about them than can be used in identity theft operations or even bilk them out of cold, hard cash. For that reason, it is important to make sure you know how to stay out there when you’re looking for free offers. There are some things you can do to make sure you freebie hunting only brings you good times – these common sense rules are a great place to start. You’ve heard it a million times before – if it sounds too good to be true, it probably is. The reason you have heard it so many times is that it almost holds water. Think about the reason that companies give away free things. They’re usually not doing it for charity. They want you try to their products in the hope that you will come back to them as a paying customer in the future, and they’re doing it to build good will for their company over all. They’re definitely not doing it go broke. So consider whether the freebie offers you come across make sense according to these criteria. Does it make sense that a company will give you a free bag of their new flavor of chips or a trial size jar of their new face cream? Sure it does, because if you like it, you may buy these products in the future. Does it make sense that a company will give you an all expenses paid, two-week first class trip to Bali for you and ten of your friends? Not so much. Don’t waste your time on these too good to be true freebies – they may end up costing your big time in the long run. By the same token, the more outlandish an offer sounds, the more you have to look for the small print. Sure, maybe the hotel chain is willing to give you a free weekend in their beachfront hotel. The small print in the offer might say that you have to agree to spend 10 hours a day at a sales seminar or that the free weekend is yours after you pay for a two week stay. One particular airline ran an offer for a free coach class plane ticket from New York to London. The small print said you had to buy two, full price first class tickets on that same route before you could get the free on – at a cost of around $8,000 per ticket. Before you jump, make sure you get all of the details. Freebie offers that actually require you to shell out some money are very tricky. Sometimes they are legitimate – after all, if you are accustomed to paying full price first class airfare, a free coach class ticket can be a real score. But many times, when you have to pay to get something for free, that is a red flag that a scammer is at work. You should never send money, even for postage, to a company that you don’t know. Also, keep an eye on the costs for things like postage even if you do know the company name. If they’re asking for $50 postage to send you a free magazine, then you know something is up. Lastly, beware giving out too much personal information. There’s no reason a company giving away free shampoo needs your bank account details. Protect your private info and if you’re unsure, move on to the next freebie offer.

Fair Use Copyright Law Don’t Overstep the Fair Use Copyright Law Many people are interested in the fair use copyright law. The fair use copyright law enables people to use portions of material that is copyrighted for the purposes of criticism or as commentary. The hard part for many people is understanding what is permissible under the fair use copyright law and what is not permissible. Anyone who writes or publishes should brush up on what is allowed and what is not allowed. Using another person’s words to make news reports, to use as a comment or criticism or to use for research, scholarship, or for educational uses that are nonprofit are generally considered fair use. In these instances, the fair use copyright law allows one person or author to make use of another person or author’s work without asking permission to do so. In situations that do not fall within these specifications you are probably violating someone’s copyright if you use their work – especially if you are using another person’s work for economic or commercial gain. When you are trying to see if you can use another’s words, you should keep a few things in mind. The answer to the following questions will help you gage whether you would be violating a copyright. First, are you transforming someone else’s work or are you copying it? Second, are you going to be making any financial gains from your work that would compete with the original copyright holder? Third, do you have the author’s permission to quote their work? Just because you list the author and give credit to him or her does not protect you from infringing upon someone’s copyright. Fourth, how much of the original author’s work are you using? If you are using a substantial amount of another’s work, you are probably in direct violation of their copyright. Many publishing companies have set rules on how much material they will allow to be quoted in other sources. Some of these ranges start at 100 words or less. However, there are truly no standards to go by, so be careful. You can not assume that keeping your copying fewer than 50 words will allow you to pass under the radar – especially if the original piece is hovering around 125 words itself! Lastly, what portion of another’s work are you using? If it is the meat of the book and the most important part of the book, you are probably in direct violation of the owner’s copyright. With a little common sense it is not hard to decide if you are violating someone’s copyright. People who are truly interested in staying within the guidelines of the fair use copyright law usually do a good job of doing so. Many people push the fair use copyright law right up to the line, while others will blatantly cross over it without giving a second thought to the repercussions. When these people are summoned to court to answer for their vagrant disregard for the property and copyright of another they are usually sorry. Sorry they got caught! It is very important that people who take advantage of the fair use copyright law are held accountable for their actions. Without accountability many more people would follow in their footsteps and use another’s works as their own.
