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.
The Convenience of Online Writing Degree Programs (online writing degree programs) Online writing degree programs are not readily available, but they are growing in popularity. There are many traditional and online schools that offer online degree programs to busy writers. The online degree programs offer courses that teach students the basics of writing, including paragraph structure, theme writing, descriptive writing, tech writing, and grammar. Usually in writing degree programs, writers are given many assignments within one week, which range from analyzing the work of others to composing their own short stories and essays. The courses offered in an online writing degree program are much like the ones offered in traditional programs, and students will begin their program by taking beginner’s courses and eventually work their way up to the more advanced. The beginner’s course teaches the basics of writing, but after taking them, students will be able to take more specific courses, such as creative writing and tech writing. The online programs give students more freedom, but the workload is almost the same and students will have more and more writing assignments as they move further into the degree program. The online writing degree programs offer bachelor degrees as well as masters’ and there are many schools that offer these online programs. Chatham College is one school that offers online writing degree programs. Chatham online is the online division of Chatham College, which offers online masters’ degree programs for writers. The writing degree program offered by Chatham online offer 7-week courses and it has no residency requirement. The programs give students the freedom to study anytime or anywhere an Internet connection is available. Chatham online offers many degree options for its students, including the Master of Professional Writing degree, which gives students training to become technical writers, content developers for the web, advertising copywriters, and public relations specialist. It also offers the Graduate Certificate-Non-fiction Writing. This program gives students the opportunity to use their nonfiction writing skills and focus one subject, which include nature, environmental, or landscape writing. Students are given many writing assignments and attend many online writing workshops where their work is presented and critiqued. Once the program is finished writers will have a portfolio of their work that is of publishable quality. Another unique program is the Graduate Certificate-Writing for Children and Adolescents. The Certificate in Writing for Children and Adolescents provides students the chance to write fiction and nonfiction for children and adolescents. There are also many other colleges that offer online writing degree programs including Burlington College. Burlington College offers a Bachelor of Arts in Writing and Literature through an online program. However, this school does require a four-day residency in Burlington, Vermont at the beginning of each semester. Goddard College is also a school that offers a master’s program online. The college offers a Master of Fine Arts in Creative Writing degree through their online program. In this program, students are able to study poetry, fiction writing, creative nonfiction writing, and memoir, play writing, and screen writing. A short residency is also required for the program at Goddard College. The University of Denver is another school that offers online writing degree programs. It offers the Certificate of Advanced Study in Creative Writing. The program includes a range of courses on content and writing processes for fiction, nonfiction, poetry, and other areas of writing. There are many other colleges and universities that offer online writing degree programs including Goucher College, Lesley University, University of Central Florida, and Washington State University. Like all degrees, online writing degrees are not simple to obtain, but they can provide convenience and knowledge, which helps them advance as a writer, or develop writing skills to that will help them in the future. Web Hosting - FTP and Other File Transfer Tools Anything related to the Internet or computers is bound to introduce technical issues pretty soon. One of the earliest that novice web site owners encounter is FTP, which is an acronym for File Transfer Protocol. Seeing it spelled out, it's easy to see why those in the know quickly move to speaking in short hand. The reason web site owners soon will (or need to) become familiar with FTP is obvious to anyone who has built a site on a remote server. You have to have some way of getting the files to the remote computer and FTP is one of the most common tools. It's also one of the simplest and most efficient. FTP is composed of two parts: the client software and the server software. It's similar, in a way, to talking to someone on the phone who writes down everything you say. You (the client) make a request ('transfer this file to the server') and the listener (the server) takes the request and acts on it. That request to copy a file from a local computer to the remote one is carried out (often 'under the covers') by a PUT command, as in PUT this there. You create the web page (in the form of a file) and then PUT the file on the server. To move a file in the opposite direction, from the remote server to your local computer, your client software issues a GET command. Many FTP clients have graphical interfaces, similar to Windows Explorer, that allow you to drag-and-drop or otherwise copy the file without ever seeing the actual commands that carry it out. But it's helpful sometimes to know what goes on underneath. In tricky cases it can be an advantage to use a command line interface (in Windows, the 'DOS box', with a similar interface familiar to most Linux users). Knowing the commands and being able to use them in the command line form can sometimes help you diagnose what is going on when the graphical tools misbehave. But FTP is not the only way to get a file from here to there. In fact, your browser moves files around from a remote computer to your local one all the time. In most cases, when you type in or click on a URL, what happens under the covers is in essence a file transfer process. The web page is transferred from the web server to your local computer then displayed by the browser. Alternatively, you can sometimes even email a web page/file from your local computer to the remote server, then use an email client on the server itself to get the file and put it in a folder. That requires that you have some form of access to the remote computer. But there are many ways of doing that, such as in-built utilities in the operating system or using commercial remote control programs. Those alternatives can be helpful to know in cases where the FTP file transfer process is misbehaving. Having more than one way to accomplish the task helps you diagnose what might be going wrong. It also helps you get the job done when the usual tools aren't cooperating. The more you learn about these sometimes puzzling acronyms, the easier you can accomplish your own goals. |
