Gordon Moore’s photo
Gordon Moore, one of the Intel founders, published in a magazine of 1965 a "law" known as Moore's Law, that tells: "the number of transistor of a processor doubles every 24 month". Can be interpreted as: "every two years the processors are twice fast at the same price". That "law" it's satisfied every year, but, Will stop at sometime? Enter into "Moore's Law: In two years your new computer will be obsolete"

HD bigfoot together a HD of size of 3.5 inches
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? Continue reading "Magnetic Hard Drives: its end is near"

Procesador
At the prior post we saw how the computers are every time more fast due to the increase of density of the transistors linked to its continuous size reduction. By one hand, the augment of transistor allow make more operations by second, and by the other hand, decrease its size allows enhance the clock frequency, but this second way of optimization was stalled at 2003. See why. Continue discovering "Ghz: Why are stalled? "

camera of an optical mouse
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. Don't stop reading the rest of "How works an optical mouse"

Supercomputer
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. Read more of "The list of Top 500 supercomputers is incorrect"

de-fragmentation
In the computer science, sometimes, appears false beliefs due to the ignorance of that really occurs in the machine. This time I'm going to demystify some of this old beliefs, which say that the hard disk can't be fragmented when we run a Linux based operating system. Finish reading "What is fragmentation and the old myth of the fragmentation in Linux"
