doamin .com how to?



When it comes to domain name extensions, most people are familiar with .com. Because of this the average webmaster is scrambling to get the perfect .com domain name. Some may even forego registering a potential goldmine of a domain name in favor of getting a less popular .com. Yet, there are dozens of other domain names available, some of which have gained popularity despite not being a .com. How can a webmaster determine if their site is going to be in such a league without the traditional .com? This article will explain how.

First, a webmaster needs to evaluate the purpose of their website. If their website is designed to simply direct people to an affiliate page, then it won't really matter what extension it has, since they are only going to visit it once anyway. However, if a website is designed for repeat visits, people may not care about the site not having a .com. Sites that contain updated information, games and message boards tend to be the type of sites that get repeat visitors.

Secondly, webmasters need to consider the memorable nature of their domain name. If a webmaster is able to create a witty domain name hack, such as del.icio.us, and their content is good, it may not matter that they don't have a .com. A good site that can allow a webmaster to register unconventional domain name extensions is New.net. This site offers extensions such as .love and .free. By looking at these extensions, webmasters can start pondering ideas for their own domain name hacks. If they need help, they can always type the word or letters used in the extension in a keyword analyzer or search engine.
Thirdly, webmasters need to determine whether or not a domain name with an unconventional extension will rank higher in search engines than a domain name with a traditional one. In fact, consider the above-mentioned example of del.icio.us. Honestly, how many people are typing such a domain name in their browser? While it is certainly memorable, all of the periods associated with it are annoying. Yet, the site still has a high search engine ranking, which is probably how it's getting its traffic.

Surfers visit it from the search engine, bookmark it and never again have to be associated with its unique URL. This is the type of success a webmaster wants to emulate. Indeed, if a domain name is keyword-rich and memorable, webmasters need to definitely go for whatever extension is available for it.

Of course, this is not to say that a person must be limited to just domain name. If they want to still use .coms after using other extensions they can. In fact, the more domain names that point to a site, the more likely a search engine bot will index it higher. So, ultimately, with this strategy, webmasters will have two domain names they can work with. They can use the one with the unconventional domain name in search engine marketing in hopes of getting indexed high, while the other one can be used in printed media, where people are more likely to be concerned with the type of URL they are entering in their browser.

The 22nd Amendment

On February 27th, 1951, the 22nd amendment was ratified which made permanent a tradition that has profound influence on the philosophy of government in the United States of America. This amendment may not be the most well known amendment but its place in the fabric of American history cannot be overstated. That is because the 22nd Amendment mandated that

No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once.

The limitation of service as President of the United States to two terms was one that up until the 22nd amendment was more a matter of custom than law. It began when George Washington refused to run for a third term. But by making the limitation of power in the presidency in the 22nd amendment, the American people made a bold statement about how their government would be run.

One of the most unique aspects to how the United States of America organized its government was the concept of citizen rulers. This concept was born in the very halls and pubs where the founding fathers gathered to discuss this new country that was just getting started. By reducing the idea of a career politician, especially at the presidential level, the 22nd amendment dealt a deadly blow to the concept that America would ever be ruled by a king or a president for life.

This was clearly a reaction by America to the abuses that had witnessed by the pilgrims and immigrants that make up this great country in their homelands. They reacted strongly and negatively to the deification of kings and the virtually unlimited powers that too many times systems of royalty tended to give to their leadership. This was one of the central themes that caused so many to flee Europe, Central Asia and other parts of the world to seek a land where it was the people who were the center of the governments will, not the arbitrary ideas of a king who was cut off from the real needs of the people he served.

The way America set up its presidency was in every way an attempt to fix the flaws and abuses of the European models and refocus the center of power in government on the electorate rather than on the elected. Another aspect of the American federal system that was put in place deliberately to limit the ability of those in power to abuse that power is the system of checks and balances. This system assures that none of the branches of government, The Congress, the Presidency or the Supreme Court could dominate the other or take complete power and rule without challenge. By insuring that all in power had to answer to the opposing party and be prepared to answer to the American people for what they did and even said, this completely eliminated that chances that one part of the government would stage a coup over the other.

Accountability is a word that is not very exciting but it is the concept that has kept the American system of government healthy and in service to its people rather than putting them in service for over 200 years. 

In addition to these several highly innovative methods the founding fathers gave to this young country to eliminate the abuses of past governmental systems, they also put a system in place that assured the orderly transition of power. The system of elections every two years stopped two evils, the occurrence of a politician who served for life without accountability and a system wherein the only way to loose your job in government was by violent overthrow. As a result the American system, albeit contentious and argumentative, has been and continues to be one of the most peaceful and orderly systems of federal administration in the world and indeed in the history of the world.

Telescopes 101

Buying the right telescope to take your love of astronomy to the next level is a big next step in the development of your passion for the stars. In many ways, it is a big step from someone who is just fooling around with astronomy to a serious student of the science. But you and I both know that there is still another big step after buying a telescope before you really know how to use it.

So it is critically important that you get just the right telescope for where you are and what your star gazing preferences are. To start with, lets discuss the three major kinds of telescopes and then lay down some Telescope 101 concepts to increase your chances that you will buy the right thing.

The three primary types of telescopes that the amateur astronomer might buy are the Refractor, the Reflector and the Schmidt Cassegrain telescope. The first two are named for the kind of lens that is used. It is pretty easy to see that the lens is the heart of the telescope so the kind that you will use will determine the success of your use of that telescope.

The refractor lens is the simplest because it uses a convex lens to focus the light on the eyepiece. So the lens bends outwards for this purpose. The refractor telescopes strength is in viewing planets. The reflectors strength is in seeing more distant objects and the lens is concave or bends in. It uses mirrors to focus the image that you eventually see. The final type, the Schmidt Cassegrain telescope is the most complex and accomplishes the goals of both but it uses an involved system of mirrors to capture the image you want to see.

So to select just the right kind of telescope, your objectives in using the telescope are important. To really understand the strengths and weaknesses not only of the lenses and telescope design but also in how the telescope performs in various star gazing situations, it is best to do some homework up front and get exposure to the different kinds. So before you make your first purchase

* Above all, establish a relationship with a reputable telescope shop that employs people who know their stuff. If you buy your telescope at a Wal-Mart or department store, the odds you will get the right thing are remote.

* Pick the brains of the experts. If you are not already active in an astronomy society or club, the sales people at the telescope store will be able to guide you to the active societies in your area. Once you have connections with people who have bought telescopes, you can get advice about what works and what to avoid that is more valid than anything you will get from a web article or a salesperson at Wal-Mart.

* Try before you buy. This is another advantage of going on some field trips with the astronomy club. You can set aside some quality hours with people who know telescopes and have their rigs set up to examine their equipment, learn the key technical aspects, and try them out before you sink money in your own set up.

There are other considerations to factor into your final purchase decision. How mobile must your telescope be? The tripod or other accessory decisions will change significantly with a telescope that will live on your deck versus one that you plan to take to many remote locations. Along those lines, how difficult is the set up and break down? How complex is the telescope and will you have trouble with maintenance? Network to get the answers to these and other questions. If you do your homework like this, you will find just the right telescope for this next big step in the evolution of your passion for astronomy.

Bluetooth Technical Operations

Bluetooth is a high speed, low powered wireless link
technology that's designed to connect phones or other
portable equipment together with little to no work
required by the user. Unlike infrared, Bluetooth
doesn't require line of site positioning to work.

Current prototype circuits are contained on a board
that is 0.9 cm square, with a much smaller circuit
board being developed.

When one Bluetooth device comes in contact with another, they will automatically exchange addresses and details of capability. Then, they can establish a 1 MB link with security that they will use as required. The protocols involved with handle both data and voice, with a very flexible topography.

The technology achieves its goal by embedding tiny, non expensive short range tranceivers into the devices available today. The radio operates on the 2.45 GHz frequency band, and supports up to 721 KBps, along with three voice channels.

Each devices offers a unique 48 bit address from the IEEE 802 standard, with the connections being point to point or multipoint. The max range is 10 meters, although it can be extended to 100 meters by increasing the power. The devices are also protected from radio interference by changing their frequencies, also known as frequency hopping.
What's important, is the fact that Bluetooth devices won't drain battery life. The specification targets power consumption of the device, limiting the drain on the battery. The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use.
Bluetooth will also guarantee security at the bit level. The authentification is controlled by the user via a 128 bit key. The radio signals can be coded with anything up to 128 bit. With the frequency hopping, Bluetooth is already very hard to listen into.

The baseband protocol is a combination of both circuit and packet switches. Slots can be reserved for synchronous packets as well. Each packet will be transmitted in a different hop frequency. Normally, a packet covers a single slot although it can be extended to cover up to five slots.

Bluetooth can also support data channels of up to three simultaneous voice channels. Therefore,< it's possible to transfer the data while you talk at the same time. Each individual voice channel will support 64 KB.

From a technical standpoint, Bluetooth is very different indeed. It's the best wireless method in the world, surpassing even infrared. For communication on the go, Bluetooth is indeed very hard to compete with.
