Long distance phone calls used to be expensive. Remember the time when you spend up to ten cents or more a minute? Initially, the competition was not fierce and phone companies were making lots of profit from long distance calls. Soon, more competitors flood the marketing, forcing the price to reduce. Phone companies began to come out with unique packages and offers to get you to become their customer. Things have changed a lot since then, and many long distance call companies have folded. This is because the world of long distance calls has changed. It is now a service that you can get for free or very low cost.The cheapest option available for long distance call nowadays is through internet. Using free services like Yahoo messenger, MSN messenger or Skype, you can now call your friends in any country as long as they download the free application too. The downside of such service of course is the need to have a computer and sometimes, the quality of the voice is not very good.If you prefer to speak through the traditional telephone way, companies like Vonage and Time Warner Cable offer digital phone that comes into your home via your cable Internet connection. You can use your existing phone and keep your phone number. This type of service is cheap. Domestic calls are free. International calls are charged at a very reasonable price. For example, Time Warner cable offers long distance phone calls from the United States to Australia for ten cents a minute.Another option available is monthly subscription. For example, Verizon offers unlimited long distance phone calls for just $20 a month. For those who make regular long distance call, this is definitely a real bargain. Such package offer is also good for those who do not have cable internet in their area.One popular option that many people like to use is buying a long distance calling card. For $10, you can make hours of long distance call, depending on which country you call to. When buying a calling card, pay special attention to the initial charge per call. Some cards may advertise that you can make an hour long call for just 60 cents. But if you make several short calls, there may be a one time charge and these charges can easily build up and deplete the card value. If using a calling card, the idea is to make less calls but you can speak as long as you like.If you have a cell phone that come with free nights and weekends call, you can take advantage of your contracts that give you free long distance phone calls during these special hours.

Imagine you are part of a team working on a project that has files all over the place in folders stored on different machines, perhaps on the server and a few of the clients. One member is writing up the technical manual, another team member writes up the training guide, another pulls both of these text files down because they are road testing the guides against the machine that is being developed. In this article we are going to look at some options for you.The big question is, how do you make sure that all of these files and the project folder are always up to date and everyone is working on the same material?What about making sure that the project management is notified when someone makes a change to source material and how do they know who's done it?Keeping everyone working on the same material, and maintaining a log of changes is essential and this all boils down to being able to compare folders and files stored on different directories or machines and making sure they match or if not, that the differences are highlighted.Programmers have long used file compare software to track changes in software code that is being produced and the majority of solutions available are strictly for use on comparing text files. If you have images in the file you will need something a little more sophisticated, but a brief look on the internet will throw up a large number of file compare utility programs for you to use.ExamDiff is a freeware utility that can be downloaded and provides an easy to use GUI (Graphical User Interface) that will compare Windows files including Vista files. Completely free to download it will flag up alterations and file changes, allow you to edit the father or son copy of the file and provides a simple clear report on what is actually different down to an individual character or punctuation mark.This is pretty typical of what you will find freely available, however as the use of applications that also include graphical images and other non-text data increase eg MS PowerPoint, Publisher and so on, then you will need to be prepared to part with some money to get a compare utility that will be able to detect changes in these files. Similarly, the ability to compare a directory tends to need a more sophisticated file compare program and the better ones tend to cost rather than being free.A good example of a graphical and directory enabled file compare utility is Beyond Compare which will set you back $30 for the fully functional edition. Not only are you able to compare and sync files and folders in a Windows environment but you also can compare ftp sites to see what changes have been made to website coding and "compare folder" s containing zip files without the need to unzip all the files before running the compare utility. Beyond Compare runs a 30 day free evaluation but this does not have all the features enabled that you will get in the paid edition.
Spam, otherwise known as junk email or unsolicited commercial email; is quickly becoming on of the most prevalent complaints of internet users. Not only is it annoying, but it is quickly becoming a dangerous and potentially expensive problem for businesses as well as individuals.How is it dangerous?First and foremost, spam is one of the leading causes for clogged networks and slow connections. American Online, one of the nations largest internet service providers; transmits over 8 trillion spam email messages a year. Those messages tie up valuable bandwidth and can slow down entire networks. Although end users will rarely see a significant change in their connections, they can rest assured that a noteworthy portion of their monthly bill is paying for that lost bandwidth.Most spam includes images or weblinks within it commercial content. Although some of it is begin or at worst annoying, an increasing portion contains sexually explicit content. Spam messages frequently contain pornographic pictures or links to sex-related websites.These messages are not suited for children yet can easily be accidentally opened by minors. In addition to simple sexual content, some of the most severely sexually explicit spam can contain images of such illegal and offensive acts such as bestiality or child pornography.Aside from slowing connections or carrying unwanted pornography, spam is the leading cause of transmitted computer viruses. Computer viruses are programs which run malicious code which can damage computer systems, delete files and steal personal information. These viruses are often hidden in an email messages as attachments such as a pictures. Email transmitted viruses can render entire systems inoperable and delete important documents forever.How can you stop it?The easiest and most simple way to stop unwanted email is to employ a spam blocker. Spam blockers are manufactured by a variety of companies and be anywhere from free to costing upwards of 50$.There are three basic types of spam blocking software. The first is a key-word blocker. These programs examine the header and body of an email message looking for a series of predefined criteria. For example, a program could be instructed to flag or block any email message containing the word sex.Although seemingly straightforward, the spam blocker also has to stop any spelling variation of sex such as sexx or s_e_x. Although this type of spam blocker can do very well at stopping spam, it also has a tendency to block personal emails which may or may not contain flagged words.The second type of spam blocker is an address list blocker which blocks or flags any emails not coming from a predefined list of addresses (such as the users address book).Although this type of spam blocker does a very good job of not blocking personal emails from friends or family, it can inadvertently delete important messages from users not on the original predefined list. This can make it very easy to miss potentially important yet unexpected emails.The third type of spam blocker is actually a hybrid of the aforementioned varieties. It will filter emails from known friendly accounts directly to the inbox while holding potentially dangerous emails in the filter. The user can then go in and sort through emails from either friendly strangers (non spam emails from unfamiliar addresses) or unfriendly strangers (spam emails from unfamiliar addresses).Although these programs do require a slight amount of user interaction, they can protect your computer and keep you from inadvertently deleting important emails.
A handset might seem to be just a device tnat lets you zaiK on a cellular network, but actually, there is a lot you need to know about handsets before you go out and buy one. What do you need? What kind of form factors are available? What about the battery? Then, theres the camera to be considered. Also, if a mobile phone is to be really mobile, you need to consider connectivity options. Then there are accessories to jazz up your phone -We round off this chapter with descriptions of a few especially desirable phones.Display TypesNot only do mobile phone displays show caller information, menu options, contacts, etc., mobile phone displays these days need to be capable of displaying thousands of colours so that high-end features such as images and video playback offer the desired user experience. The followingis a brief on the various types of display technologies in use for mobile phones.LCDSLCD displays utilise two sheets of polarising material with a liquid crystal solution between them. Crystals in this suspension are naturally aligned parallel with one another, allowing light to pass through the panel. When electric current is applied, the crystals change orientation and block light instead of allowing it to pass through, turning the crystal region dark.There are two main types of Liquid Crystal Displays: STN and TFT.STNSuper Twisted Nematic LCDs use the passive matrix screen technology, which has no active or controlling element inside the display cell. Pixels are controlled by energising the appropriate row and column drive lines of the matrix from outside the display, resulting in a slow frame rate. STN screens have limited colour range and viewing angles (~15 degrees max).TFTWith Thin Film Transistor (TFT) LCDs, each pixel is controlled by one to four transistors. Typically one transistor is used for each of the RGB colour channels. Because of this direct control technique, TFT screens are also called Active-Matrix LCDs.TFT technology provides more accurate colour control, allowing it to display more colours and also offer a wider viewing angle range than other types of LCDs.OLEDOLED stands for Organic Light Emitting Diode. OLED is a flat-panel display technology that is now being used in a variety of devices. Apart from mobile phones, you can also find OLED screens on portable audio players, car audio systems, PDAs and digital cameras. The basic property of OLEDs was discovered in 1985, over a decade before the first displays were seen. Ching Tang, a Kodak researcher, noticed that an organic material glows green if you pass an electrical current through it.An OLED is made by placing a series of organic thin films between two conductors. They operate on the attraction between positively and negatively charged particles. When voltage is applied, one layer becomes negatively charged relative to another transparent layer. As energy passes from the negatively charged layer to the other layer, it stimulates organic material between the two, which emits light visible through a layer of glass. There must be blue, red, and green light-producing organic material to produce the different colours. Because screens using OLED technology produce light themselves, they do not require a backlight as compared to LCD screens. This means that OLED displays require less power and also can be made very thin. Without any other source of illumination, OLED screens can display bright images that are viewable from almost any angle.Like LCDs, OLEDs also come in passive-matrix and active-matrix flavours.Passive-matrix OLEDs are made up of a matrix of electrically-conducting rows and columns making pixels. Between the rows and the columns are the organic layers. On the other side is the substrate, the material which gives the electricity. The more cur-rent applied, the brighter the display.In Active-matrix OLEDs, there is a TFT back plate instead of rows and columns. This controls the brightness of each pixel. There are two TFT arrays per pixel: one to start and stop the charging of the capacitor, and one to provide a constant electrical current to the pixel. Active-matrix OLEDs consume much lower power than passive-matrix ones.OLEDs have the following advantages over LCD or plasma displays: New-age displays: OLEDs can bring in new types of displays, like ultra-thin, flexible or transparent displays.Power efficiency:Since OLED screens do not require a back-i hey require much less power compared to other types of displays. This makes OLED a far better choice for portable devices.
