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.
Copyright lawyer search Easy Ways to Finding a Good Copyright Lawyer Search with the Internet There are a few easy ways to find a good copyright lawyer search while using the internet, however just typing in the phrase doesn’t always work. You must know how to use a search engine; after all you don’t just want the first person that pops up. No, you want that best person for the job representing you, it doesn’t matter what your copyright issue is. If it has come to a time that you actually need to do a copyright lawyer search than chances are you are being sued or want to sue someone, this means you want someone that knows what they are doing and hopefully has a little experience under their belt.

Remember, companies pay money to have their ads on the side, maybe they are great. The only way you’ll be finding out is if you click on them and explore. You may even want to type in more than one phrase, “Copyright lawyer+intellectual property.” This search would bring up even more lawyers pages that deal with copyright issues, which is what you should be looking for in the first place.

Wouldn’t it be nice to know how they rank compared to others in this field? You can even find that out as you do are on a search for a copyright lawyer, just type it in like you did for intellectual property. Ask any questions you may have on the phone and after hanging up you may want to ask around and see if anyone you know has ever dealt with that lawyer. If you have your own lawyer you may want to ask him/her whom they may recommend that you go to in your situation. Lawyers know about others in the job and know the best way for you to get help is by using the one that specializes in whatever the need is.

You may want to call several different lawyers and get a feel for which one could best represent you. Finding information has become easier since we have the internet, many people also fall under the idea that because there is so much information they don’t need to do a copyright lawyer search when the time comes. They basically get as much information they can find and use that in court. This doesn’t always work; sometimes the other side has a good lawyer and knows more tricks than you do. Which only leaves you footing a very big bill, don’t make this mistake…hire a lawyer. 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. |
