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.
Web Hosting - Unix vs Windows-Based Hosting, Which Is Better? An operating system functions largely out of sight, or at least is supposed to. It doesn't matter to non-geeks how a file gets stored, or how memory is used, or how simultaneous processes share the limited resources available on a computer. These are among the basic functions of any operating system. Yet, you can find very passionate supporters - who offer very detailed lists of pros and cons - for every operating system. Why? Because, though the low-level functions of an operating system do their work out of sight, there are many other features that rise to visibility. Sometimes, they do so when they're not supposed to. Weighing the pros and cons objectively could consume a book. But to select a web host operating system, a manageable level of considerations apply. They can be weighed even by those who don't know a processor queue from a pool cue. Learning Curves For most web site owners, administering the site/server is just overhead. It's not something they take pleasure in doing and they have plenty of other things to worry about. Many wouldn't know how and have no interest in learning (rightly so, given their priorities). Consequently, ease of administration is paramount for such people. Whether a Unix-based site (usually Linux these days) is easier to administer than Windows depends on your current skill set and the type of tools and level of access the web hosting company provides. But in general Linux is more difficult to install and maintain than Windows and the learning curve is steeper. FTP and Control Panels Often, you don't have to care. For many, the operating system is fairly transparent. FTP file transfers to get a new web page up to a Windows server are very much like they are to a Linux-based site. The user/administrator simply doesn't see what's behind the curtain. Many companies provide other utilities that completely mask any awareness of the operating system underneath. When that's the case, the web site owner has no reason to care, until or unless they need or want to go 'inside the black box'. Performance Performance issues can be relevant in selecting which operating system host type to choose. But for the most part, that aspect is outside the web site owner's control. Overall performance can be good or bad on either system, depending on many factors that the publisher will rarely see. The issue is a wash, as far as tipping the scales is concerned. What is more likely to be seen by a web site owner, at some point in their (and their site's) development is the database product that can be used to store information. Databases Microsoft SQL Server is relatively simple to use, yet extremely powerful and can deliver great performance. But it doesn't run on Linux. At least, not without special software to emulate Windows, which usually kills performance. On the other hand, with a bit of time invested, MySQL isn't significantly more difficult to learn than MS SQL Server and there are many free installations. Cost may well outweigh other considerations for most on this issue. Programming Languages Last, but not least, there are differences in programming languages that can be (or at least typically are) used on Windows vs Unix. If you have programmers who are skilled in Visual Basic, ASP and other Microsoft technologies, then a Windows-based host will be your preferred choice. For Perl and PHP programmers, Linux is the more common platform of choice. No single factor can push you to one versus the other operating system. And, in the long run, it isn't the primary consideration, unless you just enjoy playing with operating systems. The Ins and Outs of Free Writing Contests (free writing contests) Free writing contests are available by the thousands. They are virtually a dime a dozen on the Internet. No matter what your niche is in the writing community there is a free writing contests out there for you. How do you know which ones to enter and which ones are legitimate? That’s simple. You do what you do best-- research. While providing the story for the free writing contest will probably be the easy part, researching the thousands of available contests will be a daunting task. If this is un-chartered water for you, you have the start at the beginning. Finding what free writing contests are available. Grab a notebook or start a word document and list the contests that are available. Beside each contest name you will want to put what kind of writing they are looking for and when it needs to be done by. By doing this first you will be able to eliminate any that do not coincide with your writing niche or with your schedule. Now the free writing contest research begins. Finding out if a contest is worthwhile and legitimate is comparable to running a background check on a person. First check the contest website. Do they have all contact information available? Do they tell you what company is hosting the contest? If they are not, you will have likely found warning number one that it is a scam. So scratch those off your list or at least move them to the bottom until you can find out more information on them. Start asking around to colleagues and writers groups. Search the writing forums and the Internet scam sites. The Better Business Bureau is also a good place to look. Once you narrowed the free writing contests down to the legitimate ones, read the contest rules and regulations. Some contests require you signing over all rights to a story even if you don’t win. Are you willing to do this? Giving up rights to you writing is a lot easier to do when you are getting something in return. After you enter there is no going back, so make sure this is what you want to do. The final thing you need to look for is if the contest is just a cover up to get you to buy services or products. This does not necessarily mean they are a scam or don’t actually award winners. It simply means that they will try to entice you to use their critiquing services or offer you a book at a reduced fee that your work will be published in. Being published sounds like a great deal but is it a book that carries prestige that people are going to see? Many authors think that writing contests will launch their career into a successful endeavor. This is not the case, especially for free writing contests. Even winning the grand prize of a smaller known contest is not going to affect your literary journey. Even though they may not springboard your career, there are good reasons to join writing contests. You will get unbiased opinions and valuable feedback from the judges. If you make it into the higher rounds, editors could also see your writing. Ultimately whether you enter a free writing contest the choice is yours. Just ask you self if the time spent writing and researching the piece you choose to enter is worth writing for free in most cases. The critique and feedback may be the most worthwhile thing you receive from the contest. But then again the judges opinions are a dime a dozen just like the contests. |
