On 1980, Steve Kirsh and Richard F. Lyon developed independently the first prototypes of optical mouse, technology that will began to replace the old ball mechanical mice in the 2001. Opposite to the mechanicals, the optical mice can't stuck by the dirt and are lot of more precise. Here you will discover how works exactly. Learn more about "How works an optical mouse"

The hard drives increase its capacity every time more fast, its growing seems to be imparable, but the technology have its limits and nothing is infinite. When we will arrive to the limit of the hard disk? Enter into "Magnetic Hard Drives: its end is near"

Somedays ago I wrote about a chinesse supercomputer, the Tianhe-1A that was proclaimed the most fast on the world for achieve the most hight position of the Top 500 list. Now, an executive, provider of high performance technology, in the supercomputation conference of the 2010, celebrated in New Orleans, give me the reason saying that using together 100.000 smartphones with Android that number can be superated. There are a lot of people that is realizing that the Top 500 doesn't use the best way to measure the performance. Don't stop reading the rest of "The list of Top 500 supercomputers is incorrect"
