THINGS YOU NEED TO KNOW

Li-Fi   technology   A new technology, known as Li-Fi, could one day offer internet speeds one hundred times faster than the Wi-Fi we use today. Scientists have achieved speeds in the lab of up to 224 GB per second. Like radio waves, visible light is part of the electromagnetic spectrum. The difference is that viable light has a spectrum 10,000 times larger than radio waves. This means Li-Fi has the potential for enormous capacity. Instead of transmitting information via one data stream, visible light would make it possible to transmit the same information using thousands of data streams simultaneously. That’s the equivalent of downloading 18 movies in the blink of an eye. Li-Fi, or light fidelity, is now moving to trials in the real world, with office tests in Tallin, Estonia achieving speeds of 1 GB per second, 100 times the speed of traditional Wi-Fi. Is it end of Wi-Fi? Li-Fi probably won’t bring about the end of Wi-Fi. At least not for the foreseeable future....

Money is everything for Google ! It' true. Recently google did it again,after a long battle between Google and one of the developer of the add-on( Streamus). Streamus, the Chrome extension that turns YouTube into a serious music service, has been neutered by Google. The tiny extension made YouTube into a viable music service by offering a button in your browser for quickly building a queue of songs and playing them in the background. Sean Anderson , a 25 year old developer based in California bet everything on his tiny, but incredibly useful Chrome extension.  At first, the extension was picked up by a few friends but it quickly gained steam in January of 2014. credit:google Stramus image It was always somewhat questionable, because it played music in the background without the video that went with it — Anderson seemingly knew this, but had hoped he would one day be able to work something out with YouTube if it got big enough. It feels like something that Googl...
