Trojan horse

In the context of computing and software, a Trojan horse, or simply trojan, is a piece of software which appears to perform a certain action but in fact performs another such as transmitting a computer virus. Contrary to popular belief, this action, usually encoded in a hidden payload, may or may not be actually malicious, but Trojan horses are notorious today for their use in the installation of backdoor programs. Simply put, a Trojan horse is not a computer virus. Unlike such malware, it does not propagate by self-replication but relies heavily on the exploitation of an end-user. It is instead a categorical attribute which can encompass many different forms of codes. Therefore, a computer worm or virus may be a Trojan horse. The term is derived from the classical story of the Trojan Horse.

The Apple iPhone has supported Yahoo! push e-mail since the phone's initial release in 2007. Since July 2008 the release of iPhone 2.0 software brings Microsoft's Exchange ActiveSync platform to Apple's handheld thus allowing the iPhone to synchronize e-mail, calendars, tasks and contacts with a Microsoft Exchange Server. The software which will add features commonly found in enterprise mobile devices will be available through iTunes as a free download. MobileMe stores all your email, contacts, and calendars on a secure online server — or “cloud” — and pushes them down to your iPhone, iPod touch, Mac, and PC. When you make a change on one device, the cloud updates the others. Push happens automatically, instantly, and continuously. You don’t have to wait for it or remember to do anything — such as docking your iPhone and syncing manually — to stay up to date.

Robot kit

A robot kit is a special construction kit for building robots, especially autonomous mobile robots.

Toy robot kits are also supplied by several companies. They are mostly made of plastics elements like Lego Mindstorms and the Robotis Bioloid, or aluminium elements like Lynxmotion's Servo Erector Set and the qfix kit.

The kits can consist of: structural elements, mechanical elements, motors (or other actuators), sensors and a controller board to control the inputs and outputs of the robot. In some cases, the kits can be available without electronics as well, to provide the user the opportunity to use his or her own.

A roboticist designs, builds, programs, and experiments with robots. Since robotics is a highly interdisciplinary field, roboticists often have backgrounds in a number of disciplines including computer science, mechanical engineering, electrical engineering, and computer engineering. Roboticists often work for university, industry, and government research labs, but may also work for startup companies and other entrepreneurial firms. Amateur Roboticist is also a growing hobby all over the world.
