solution to laptop computer theft: a program that lets owners give their property a voice when it has
been taken.
The program allows users to display alerts on the missing computer's screen and even to set a
spoken message. Tracking software for stolen laptops has been on the market for some time, but this
is thought to be the first that allows owners to_give_the_thief_a_piece_of_their_mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model:
a red and yellow "lost or stolen" sign appears on its screen when it is started. Under the latest version
(版本)of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.
"One customer sent a message saying, 'You are being tracked. I am right at your door.'" said Carrie
Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop's speaker will say
"Help, this laptop is reported lost or stolen. If you are not my owner, report me now."
The Retriever software package, which costs $29. 95 but has a free trial period, has the functions
of many security software programs. Owners can remotely switch to an alternative password if they
fear that the thief has also got hold of the access details.
If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet
service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops
increasing, the number stolen while their owners are out has been rising sharply.

Basic Math introduces students to the basic things of mathematics, as well as some easy methods of learning it. These 30 fantastic courses are designed to provide students with understanding of arithmetic and to prepare them for Algebra (代数) and beyond.
The lessons in Basic Math cover every basic field of arithmetic. They also look into exponents (指数), the order of operations, and square roots. In addition to that, students also discover how a particular mathematical topic relates to other branches , and how they can be used practically.
Basic Math starts from easier concepts and gradually moves on to the more troublesome ones. The lectures offer students the chance to understand of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and develop confidence in this amazing field of study.
With the help of these lectures, they will be able to clear away the mystery (神秘性) of mathematics and face their studies with more confidence than they ever imagined. Besides, they will strengthen their ability to accept new and exciting mathematical challenges.
Professor H. Siegel, honored by Kentucky Educational Television as "the best math teacher in America, " is a devoted teacher and has a gift for explaining mathematical concepts in clear and interesting ways. From the basic ideas to the more difficult problems, he is a master in making math lectures learner-friendlier and less frightening
With a PhD in Mathematics Education form Georgia State University, Dr. Siegel now teaches mathematics at Central Arizona College.
If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer. Or you can get your money back.
