Web Hosting - Domain Name Changes and How They Affect You New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it. When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties. One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another. Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here. DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low. In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was. A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed. The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world. Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching. In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data. A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed. Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random. But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies. That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely. In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address. So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.

What to Think about While Choosing a Writing Desk (writing desk) Writing desks come in many shapes and forms. The technical definition is a piece of furniture with a surface for writing, with drawers and pigeonholes for writing materials and a portable case that when opened forms a surface on which to write. A writing desk could be as complex as that definition or as simple as a desk for writing. Basically a writing desk can be anything that you want it to be. You may not need to buy a writing desk. You may be perfectly comfortable with one you already have or working on the couch or at the kitchen table. This is fine. If it is a cohesive work environment for you that is fabulous, but some writers require a more formal, dedicated area just for them. By finding the perfect writing desk, you are on the way to the start of creative that work style atmosphere that they need. Before you begin your writing desk shopping venture you must first have two things picked out. The area in which your desk is going to go and the chair you are going to use. The location of the desk is important because it will be necessary to choose a size and style. The chair is important for comfort and maybe an important factor in determine the correct height of desk needed. Once these are figured out you shopping journey is ready to begin. While shopping for a writing desk the most important feature is comfort. You need to sit at the desk for most likely for hours at a time. Having a desk at the right height is imperative to this. With the writing surface being to high or to low will not only be uncomfortable but also will more that likely make it difficult for you to concentrate and write. Having a writing desk that is not the correct height is likely to cause neck and back strain. The function and the size of your writing desk are the next factors you need to consider before you purchase one. Do you need one with a little storage or a lot? Does it need to have an adjustable surface or can it just be flat? With all the choices available assessing what you need can help narrow down the ones that will work for you. How big of a space do you have for it? These are some simple considerations that are often forgotten while buying a writing desk. It would be terrible to fall in love with a desk and bring it home just to find out that it is not going to fit. The next important thing is style. When choosing the style of the writing desk you will want it to flow with the furniture already in your home. If your home is modern or contemporary you may want to choose one of the metal and glass desk designs or perhaps one with light wood tones and metal accents are right for you. Another great writing desk available is called the secretary. The secretary is wooden desk with drawers on the bottom and a fold down writing surface. They are usually compact in size but have ample storage and often offer shelving covered by glass doors on top. Plus having a fold down writing surface, it is easy to close up when you are done and hide you space altogether. Choosing the writing desk that is right for you may not seem that important. I mean how difficult could it be to choose a surface to write on, right? But making sure comfort, storage, and style fit into your lifestyle is an important decision. This is part of creating a suitable working environment for you to produce your work.

Copyright Infringement Play It Safe: Making Sure You're Not Committing Copyright Infringement Copyright infringement is not an easy thing to explain. While it may seem as simple as not using someone else’s work, it’s not that easy. Thanks to the Electronic Frontier Foundation, and many other organizations, we have the ability to use others’ works – as long as we use it under ‘fair use’ laws. So what does fair use have to do with copyright infringement, and how can you utilize it? Fair use laws are the conditions in which you can use a copyrighted work without having to pay someone royalties. This includes when you use a copyrighted work for educational or instructional uses, criticism of the work, commentaries on the work, news reporting about the work, teaching on the work (including multiple copies for classroom use), scholarship uses, and research. This is talked about fully in Section 107 of the Copyright Code (commonly called Fair Use) and is available for you to read at your local library. Copyright Infringement in day-to-day life Sometimes, if you’re writing a paper for work or school, or if you are creating a Power Point presentation, you need to use someone’s work that is already in copyright. So how do you use it without committing copyright infringement? All you have to do is ask – the worst they can say is no, right? But, if they do say no, there are several items in the public domain which may help you to finish your project without having to commit copyright infringement. What is the public domain, and how does it relate to copyright infringement? Material that is not copyrighted is considered in the public domain – you cannot commit copyright infringement on works in the public domain. These works include things that the copyright has expired on, or is not copyright-able – such as government publications, jokes, titles, and ideas. Some creators (writers, musicians, artists, and more) deliberately put their work in the public domain, without ever obtaining copyright, by providing an affiliation with Creative Commons. Creative Commons allows people who create materials to forfeit some, or all, of their copyright rights and place their work either partially or fully in the public domain. So, how do I ensure I’m not committing copyright infringement? First of all, if you’re going to use someone else’s material, you may want to check the public domain to see if something is suitable for use, instead of trying to use someone else’s copyright. However, if you can’t find something suitable (and you can’t create something yourself), the next best thing (and your only legal course of action) is to find a piece that is in copyright, and contacting the copyright holder. When you contact the copyright holder, make sure you tell them what you want to use their piece for – whether it’s for your blog, podcast, or report – and ask them if you can use it. You may have to pay royalties, or an attribution in your piece, or a combination of both. The creator may also place many limitations on when and how you can use their material. Follow all these instructions they give you, and you’ll be free and clear to use their work as you want. Once you have permission to use a copyrighted work, you need to make sure you stay within the agreed-upon boundaries - if you veer outside their agreed terms, you may open yourself up for a copyright infringement lawsuit – which can be nasty, costly, and time consuming. If you’re in doubt, before contacting the copyright holder, contact a copyright lawyer to ensure you’re following the law – and protect yourself!
