Because of the close of the last factory of typewriter (Godrej and Boyce), I'm going to talk about the distribution of the keys on a computer keyboard, because they have inhereted the distribution of its keys. This is a fateful contribution to the computer world, do you want to know why? Read more of "Why that position of the keys?"

Formerly, when still the CRT (Cathodic Ray Tube) monitors were in use, emerge the myth of cactus that absorb the monitor radiations. This swindle probably was thought by some illuminated herbalist that saw the bulky filters antiradiaton that was putting in front of the screen. Surely though that he can win a lot of money selling cactus as substitute of this filters, because a cactus is a lot of more nice and friendly than an authentic filter antiradiation. Follow reading if you want to know why this belief is absurd. Read all about of "The myth of the antiradiation cactus"

Today I'm going to dedicate the post to explain some basic concepts about the files that the 99% of the people that use a computer don't understand it very well.
Some users know that the last letters that there are at the end of a file (the extension), identifies the type of file, so, for instance, an archive ended in .JPG is a type of file of image and another ended in .GIF is a different image format with other characteristics. This, is true for most cases, but causes confusion in the cases where the extension isn't of a concrete format, unless of a format container. Read the rest of "Differences between extension and format in a file"

The same as others disciplines as mathematics, the informatics don't have Nobel prize. So a equivalent award, had to be invented in computer science, called Turing prize, in honor to Alan Turing, that did important contributions to the computer science in the beginning of it. Don't left of read the rest of "Turing prize (the Nobel of the computer science)"

According to the IANA (Internet Assigned Numbers Authority), the organization that assign the IP addresses, in February of 2011 all the IP addresses will be occupied. The solution to this problem is being implanted, approximately from the year 2000 and will follow implanting during a lot of years more. This consists in replace all the software and hardware that use the IPv4 protocol to another that use the IPv6 protocol. Surprise yourself with the rest of "What will happen when the IPv4 addresses will be exhausted?"

We absorb massive doses of WiFi radiation all the days, is important that we ask us if the WiFi signals are or are not harmful to the health. In this post I'm going to explain some known facts and in the next one I will deepen about the scientific studies that talk about this topic. Read the rest of "Are WiFi Networks healthy? (I)"
