Important steps in installing a satellite dish

With the recent breakthroughs in the communication world, DSL connection has already become a household term. It has already been launched in various areas across the world; however, obtaining a high-speed access to the Internet via satellite is a technology that is still unavailable to many television users because of lack of facilities. At present, the solution to this limitation can now be achieved through the satellite dish network. Whether you live in an area with DSL access or not, you can now utilize DSL technology to the extreme.
If you intend to use satellite dish for your homes or offices, you must receive transmitted signals through a clear view of the southern hemisphere. You must ensure that your chosen location is free from any obstruction like trees, buildings and other structures that can alter your signal and in effect, cause poor reception. If your site is free from any obstruction, it is not necessary to locate the co-ordinates until later when you decide to install the dish system. When you live within these areas, you can install your dish on a galvanized pole that is cemented in the ground or by positioning it no further than 100 ft. from your area.
To give you a better idea regarding this, here are some steps to install a satellite dish successfully and get it authorized:
„X First, you must know the satellite service in your location. Say, if you live in Europe, you can choose between AFN and Direct to Sailor (DTS). The former has a greater number of channels available but doesn¡¦t have worldwide service while the latter has worldwide coverage but has fewer program channels.

„X Next, you must find the technical information on the satellite that will be used in the whole process. Then, you have to search for the ¡§look angle¡¨ ¡V this is the direction in which the satellite dish has to be pointed to get the signal.

„X Finally, set up the system all together by assembling and pointing the satellite dish, connecting and programming the decoder. After selecting the proper location, you have to distinguish where to mount the dish. To get the best reception possible, it is advisable that you mount the dish outside your home or office such as in surfaces like roofs, decks, chimneys, etc. Most areas will be pre-wired with the correct RG-6 coaxial cable used in both satellite TV and cable services. You must also pre-install external outlets in each room where the televisions are situated. Take note that you must always install RG-6 cable and not any other type of cable.
In addition, you can also place a satellite receiver at the vicinity of the cable outlet in your home or office depending on the number of televisions connected to the satellite system. The said receivers are like a smaller version of a VCR that actually processes the signal from the satellite dish to your TV for sharp, stunning, digital quality pictures.
If the location that you have chosen is questionable and you are planning to install the satellite dish yourself, you might need a compass and position yourself towards the southern hemisphere. You will first need to know the correct azimuth ¡V the horizontal direction of your dish and the direction of the communications satellites in orbit ¡V and your elevation co-ordinance. You have to expect these elements to differ by geographical location.
Furthermore, major satellite TV providers namely: DirecTV and Dish Network have ¡§satellite dish pointing basics¡¨ on their sites that are established by your zip code. And if you intend to make use of terrestrial DSL, the variant via satellite will perfectly suit you. With it, you will benefit both by saving your charges and valuable time. While you pay the low fees for the channels you receive, you can also find service providers that provide you with hundreds of dollars of satellite TV equipment including dish, receivers, etc. for free.

RFID for Beginners

RFID technology is used frequently today and has been around since the 1920s, but not many people know about, or understand it. RFID stands for Radio Frequency Identification and is used to store and retrieve information. This information is stored and retrieved using RFID tags or transponders. RFID tags are small and can be incorporated into many products. The tags have antennas that allow them to receive and respond to radio-frequency queries from an RFID transceiver.

Two Types of RFID Tags

There are two types of RFID tags; active tags, and passive tags. Passive tags do not have their own power supply, but rather receive their power from a tiny electrical current present in the antenna that is induced by an incoming radio frequency scan. Because of the small power present in the system, passive RFID tags are used only in short distances (such as an ID card).

Active RFID tags have a power source and therefore are much stronger and can be used over larger distances and are therefore more highly effective. Active RFID tags also have the potential to store more information than their passive counterparts. Some active RFID tags have a battery life of up to ten years.

The System of RFID

RFID works off of a system that relies on tags, tag readers, tag programming stations, sorting equipment, circulation readers, and tag inventory wands. RFID is generally used in security, because security gates are programmed to read the RFID tags and then either open or close accordingly. The system helps the information be easily transmitted via an RFID device. Systems have evolved over the years along with RFID chips. The hope is that RFID will one day be available to everyone (meaning consumers) because it will be more efficient and cost effective to implement RFID processes.

Where is RFID Used?

RFID can be found almost everywhere. RFID can be found in bookstores and CD stores. The little alarm that sounds if a CD has not been scanned is made possible by an RFID chip. RFID chips are found on animal tags, on books in libraries, in car alarms and car lock systems. RFID can also be used to detect motion. This could be very useful in the coming years in terms of prisons. In 2004 the Ohio Department of Rehabilitation and Correction (ODRH) approved a $415,000 contract to test RFID technology in prisons. The idea is that the prisoners will ware wristbands that will watch their movement. If there is any movement, which is out of the ordinary, security will be alerted. This technology will be employed in many states in the coming years.

Conclusion

RFID technology seems to have endless possibilities. Some critics of RFID technology say that it violates the privacy of citizens. This is based on the fact that RFID can be used to track whereabouts of people and obtain personal information. Putting all of this power into a little chip makes it undetectable. However, RFID can also possibly be used in driver’s licenses for faster police scanners, and as a way to monitor hospital patients. With every potentially harmful application of RFID, there are several wonderful applications. It will be interesting to see all of the wonderful applications of RFID in the future.

Understanding Email Netiquette

In life, it is the moral responsibility for the elder to teach the younger, or for the
experienced to teach the inexperienced. In internet life, the same moral responsibility a
pplies in regards to correct use of email.

One large difference is that, in internet life, it is very often the younger who are the
experienced. The current waves of growth in internet usage, the new users, are largely
from the older generations.

Accordingly, it becomes the responsibility of the experienced users to educate and train
newer users in the correct usage of email. One simple way of imparting this education to
lesser experienced internet users is to politely refer them to this article, either on the
page you are currently reading or at http://BestPrac.Org/articles/netiquette.htm

The internet life carries it's own versions of courtesy, privacy and security issues that
all users need to know. Hence a new word has entered the vocabulary - Netiquette.
(Internet etiquette.)

For example:

In internet and email culture, ALL CAPITALS IS AKIN TO SHOUTING and is universally seen as
rude and impolite.
New email users often forget to include a brief "Subject" line on their emails, or do not
understand the importance of it. Ordinary postal service "snail-mail" does not ordinarily
require a heading about the contents of the letter on the outside of the envelope - though
most posted periodicals and many commercial accounts nowadays do identify the contents or
level of importance on the outside of the envelope. Email, however, operates very
differently from snail-mail. Never omit a subject line, and keep your subject line brief
and relevant. Without a subject line, your email will probably be seen as yet another junk
email and be deleted unread by the intended recipient. More commonly, it may not even reach
the recipient at all. Many ISPs filter suspicious looking emails and delete them without
delivery. A blank subject line to an email filter is like waving a red rag in front of a bull.
Never send emails to people you do not know without their express permission. Only send
email to people who you know, or who have clearly indicated that they want to receive
correspondence from you. Violation of this act of Netiquette can land you in all sorts of
trouble. You will be labelled as a spammer. In some states or countries, you risk being
charged with criminal or cival violations of the law for sending unsolicited email. Even
in countries or states where there is no specific law prohibiting unsolicited email, it is
regarded as bad manners and offensive. If you check with your ISP, you will almost always
find that they reserve the right to terminate your internet connection if they receive
complaints about you for sending unsolicited email.
Even when sending email to people that you do know, only send them what they are likely
to want. Not everyone you know wants jokes or other "chain email" forwarded to them. Not
everyone shares your sense of humour or has the time while connected at work to be reading
frivolous emails. If you like forwarding jokes or other "chain emails" to your friends,
check with them first to be sure they are happy to receive them.
Think before you type. Type, then think again. Unlike face-to-face or voice-to-voice
communications, the easily and quickly typed email can all too easily be a source for
expressing your feelings in the bluntest of ways. Similarly, the hastily written word may
lack feelings and not express the emotions that can be sensed with eye contact or voice
modulation in other forms of communications. It is too easy to forget that there is a human
at the other end - not just a computer. You can very easily damage your own reputation and
destroy friendships with thoughtless emails. Once an email is sent, you cannot retrieve it.
The damage is done.
While to the experienced user all of the above is simply common sense, as the old saying
goes "Common sense is not really all that common." These basics are not innate within the
human sole. Newcomers need to be taught.

When to use To:, CC: or BCC:

Another vital area of appropriate email usage goes beyond merely being courteous in your
communications - the correct use of To: or CC: or BCC when adding recipients to the email
your are sending.

All popular email software and all web-email accounts give you a choice of these three
different ways to add a recipient for your email. (Sometimes you might need to check your
software menu and enable BCC as a visible option. It is not a visible option by default
in all email software, unfortunately.) Your choice has vital privacy and security implications,
so it is important to know which to use and when. While "To:" is self explanatory, a brief
definition and history of CC: and BCC: will help you understand their correct usage.

CC: is a term from old fashioned typists. It stands for "Carbon Copy". In days of old,
prior to photocopiers or word processors with laser printers, copies of letters were made
by inserting two sheets of typing with a sheet of carbon paper in between into the typewriter.
When a secretary typed a letter that was meant for one person though another person
(other other people) was to receive a copy, and the first person was to be informed that
a copy was being sent to another person, the typist would add a line under the signature
at the end of the letter, along the lines of:

CC: Joe Bloggs.
Jane Smith.

This convention alerted to direct recipient to the fact that the letter had also been sent
to other specific people.

If you did not want the direct recipient to know that copies were sent to other people,
you'd simply not include a CC: line at the end of the letter.

BCC: stands for "Blind Carbon Copy". It is the electronic equivalent of sending a letter
to multiple people without a CC: line. It means that people receive the email without any
trace of who else is also receiving it being revealed.

Given those definitions, there are simple guidelines as to when you should use
to:, CC: or BCC: in the emails that you send:

If your email is being sent to just one person or email address, place it in the
"To:" section.
If your email is being sent to more than one recipient and all the recipients truly
need to know who else is receiving it, put all the addresses in the CC: section.
If your email is being sent to more than one recipient but there is no urgent reason for
all the recipients to know the names and email addresses of everyone else to whom it is
being sent, put all the addresses in the BCC: section.
(Some email software requires at least one address to be placed in the To: section.
If yours insists on this when you are trying to send a CC or BCC email, put your own email
address in the To: section.)

Understanding these basic principles of email usage has many benefits. It preserves the
privacy of your contacts. It prevents lists of names and email addresses being sent to
strangers when someone you send an email then forwards it to others. It helps to prevent
viruses, worms and trojans being accidentally spread by your friends with out-of-date
antivirus programs.

Most of all, it shows the people with whom you communicate that you are sensible and
responsible in your online behaviour. It shows that you take their privacy and security
seriously. It builds trust in your communications.
