How Will Wireless Power Change Our Daily Lives?

Stemming from the aspirations of the famous nineteenth-century physicist and engineer, Nikola Tesla, the notion behind wireless power has been around for decades. The idea has been vaguely implemented into commercial and military use but has yet to reach the mass-consumer market. There’s no doubt that the world is going wireless with the recent popular expansion of cellphones and Wi-Fi internet but the last remaining obstacle to remove all wiring is power. The day we eliminate these wires is soon at hand and could provide an inordinate amount of benefits to both businesses and consumers. Currently, the most common method of transmitting electricity through the air, now dubbed “WiTricity”, uses a main copper coil amplified by electricity, creating a magnetic…

How to Crack Wi-Fi

Your Wi-Fi network is your conveniently wireless gateway to the internet, and since you’re not keen on sharing your connection with any old hooligan who happens to be walking past your home, you secure your network with a password, right? Knowing, as you might, how easy it is to crack a WEP password, you probably secure your network using the more bulletproof WPA security protocol. Here’s the bad news: A new, free, open-source tool called Reaver exploits a security hole in wireless routers and can crack most routers’ current passwords with relative ease. Here’s how to crack a WPA or WPA2 password, step by step, with Reaver—and how to protect your network against Reaver attacks. In the first section of…

The Pros, Cons and Ethical Concerns of Telework

I believe that the progression of technology has helped the telework in many ways for instance its helped with wireless devices, web applications and tools such as online meeting software which I believe has made it so much easier for employees to interact with their managers, supervisors, or even other employees even when they’re not in the office. I believe there are a number of reasons to why people would rather telecommunicate rather than having to sit in a hot stuffy office all day. They are more able to focus on what needs to be done rather than having to worry about people bothering them all day and looking over their shoulders, they are able to avoid having to do…
