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 - 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.
Explaining How Credit Scores are Used in the Hiring Process You might be wondering why credit scores are used in hiring processes. While you may have never heard about it, it is actually a more common practice than you might think. Companies and institutions such as banks, universities, retail stores, financial institutions across the United States use credit scores to determine whether an applicant is good for the open position or not. Even though you might think that this is illegal, it is not. In general, it is a legal undertaking for companies to look at your credit score. This is yet another reason why you should make sure that your credit scores are good and up to date. So why would they be using your credit information in a hiring process? For some of these companies, employees will be exposed to a lot of money and have a financially responsible position. Your credit information can actually help them determine whether you are a financially responsible person or not. Companies think that if you cannot handle your own money, why you would be qualified to handle their money? On the one side, if you think about it, it is a very valid thought. On the other side, the credit history will not tell the company how you might have gotten all the debt. What if one of your family members is really badly sick or a similar situation? In this case, you have not been irresponsible with your money, but you saved a family members life. You might have been willing to take on all this debt and then work from there. Sometimes numbers are just not an accurate representation of your life. Companies that do use your credit are not only determining whether you can handle money, in some instances they use it as an indicator for your character. It will tell them if you are responsible with your money and finances you are a responsible person. A person that will not be tempted by money or certain situations in a workplace is a person they can securely trust with their funds, their tasks or their great projects. One thing is for sure, the company needs to let you know that they are going to check your credit history in their hiring process and they also need to let you know what they are checking for. The criteria they are looking is the criteria they have to tell you about before you give them the permission. Unless they tell you and have a signature of permission from you, they are not allowed to check and use your credit history. If they miss these above mentioned steps, you do have a case in you hands that you can bring to the court. In some instances, some of the people that were not told about the credit check and have been denied have had a good case in their hands. But as with so many things in life in the United States it pays off to have a good credit history and such a check will not ruin your career moves. Check your credit history every year since once a year the big credit companies do have to give you a free credit report. In the case that you find any wrong or dubious items on your account go ahead and dispute them. Oftentimes companies might just have put a claim against your account that is not really caused by you. Why do companies do that? Money has caused many bad things in the world and a company that wants their money back is going to run after any lead they have. Therefore disputing your case and putting your credit score back to normal can be an essential part in your application and hiring process with some companies.
The Top Virtually Bug-free Free Email Services on the Net Virtually bug-free e-mail services are available actually from several places. Many of these service providers are big names, known by many, especially Internet users. The difference between the different e-mail providers lies in several things. These differences include but are not limited to plenty storage space, effective spam filtering, a fast user-friendly interface, desktop e-mail program access and much more. Currently in the United States and the rest of the world, the best offer for free e-mail comes from Gmail. Gmail is part of the Google business enterprise (the search engine most of us know) and offers the most features and storage space for their users for free. With virtually unlimited storage capacity for e-mails, a user never has to delete any e-mails of the server and can collect all the messages. Gmail offers a simple user-friendly interface, which also includes an excellent search function that lets a user find messages instantly and precisely. Another great feature of gmail is the POP and IMAP access features. This gives the user the possibility to download the e-mail from the server with any e-mail program that the user generally would use. The program can then also automatically download the e-mails into the program ready for the user to read. Gmail is funded by displaying advertising next to the e-mails read. Next on the worldwide list would be GMX, a German provider that offers many of the features gmail offers, but with limited storage space. This program also has the POP feature and can therefore be used in conjunction with any of the common available PC e-mail programs. Right after gmail it is one of the most reliable e-mail services, but unfortunately they discontinued the English user face and only offer a German version now. Thereafter on the top free e-mail services providers is AIM Mail. It is the free web-based service from AOL. Like gmail it offers virtually unlimited online storage, excellent spam protection and a simple, easy to use interface. Unfortunately, AIM Mail lacks proper productivity, such things as labels, smart folders and message threading is not available. AIM Mail also offers a very functional POP and IMAP access. Yahoo! Mail would be the next e-mail service that should be mentioned on the list of the top virtually bug-free services on the Internet. Yahoo also offers virtually unlimited storage space for e-mails and a few other nice features, such as Short message services for texting to friends and family, instant-messaging features for the internet and up to date news feeds. What Yahoo! mail lacks is a really good spam filter. It offers a spam filter, but it is not effective enough. Also nice to have would be labeling options as well as smart folders. The Yahoo! Interface is just as easy and user-friendly as the other providers and fairly reliable. To complete the list we need to mention the following three services, Inbox.com, FastMail and Hotmail. Inbox.com offers e-mail users 5 GB of free space to store e-mail online. Despite the limited space, this service is outstanding due to its high-speed accessibility. Web access and POP access are very fast and even the search functions are faster than with most other services on the market. The drawbacks of Inbox.com are the missing IMAP access, only POP is provided and the organizing of mail is slightly unorganized due to missing smartfolder technology. FastMail on the other hand offers users only IMAP. It has many useful features and has one of the best web-based e-mail interfaces. It also generally displays fewer ads then the other services do. And lastly, Live Hotmail should be mentioned here, since most PC users that have a Windows based operating system will have heard of hotmail. This program offers 5 GB of storage for e-mails online. It has a fast search option, a solid security feature and the interface is as easy as the ones users are used to on their desktop. Even though security is great, the spam filter is not quite as effective as some of the other e-mail providers. Also missing with this provider is the POP and IMAP access as well as smartfolders and other great e-mail organizing features.
