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. Continue reading "The myth of the antiradiation cactus"

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. Enter into "Turing prize (the Nobel of the computer science)"

The Christmas arrived, the streets are full of led diodes of high luminescence, the house of Christmas trees of optical fiber, the computers of USB ornaments and Santa Claus brings robots and computers to the children. A lot of technology to celebrate the born of Isaac Newton as must be. In this post I'm going to talk about how works the Christmas trees of optical fiber. Continue discovering "Christmas tree of optical fiber"

A photo has been converted in the standard of reference in the computer sciences. Over this have been applied, from the years 70, a big quantity of algorithms of graphic computing, compression and artificial intelligence. Fill your mind with "The photo of Lena Söderberg"

Not a lot of time ago has been resumed one of my favourite series, Futurama, realized by Matt Groenning, the creator of the Simpson.
Between the scriptwriters of Futurama are involved several scientist that provides continuously references to the science. In this post I'm going to explain the cryptography used in the series for code some alien inscriptions. Read the rest of "The Futurama code: First part"

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. Follow reading "Differences between extension and format in a file"

When Ray Tomlinson invented the e-mail in 1971, surely he didn't thought that the at sign, will convert in an Internet symbol (Arpanet in that moment). Finish reading "History of the at sign"

Neither me nor anyone knows if the radiations of WiFi networks and mobiles are bad to the health. There are an infinity of scientific studies about the effects of the electromagnetic non-ionizing radiations in the health, the fifty percent says that there are not evidences that prove that exists adverse effects, and the other fifty percent assert that there are. Enter into "Are WiFi Networks healthy? (II)"

The screensavers, theoretically, serve to protect the monitors from the deterioration of the quality of the screen produced when you leave an image fixed during a lot of time. With the abandon of the CRT monitors in favor of the TFT-LCD, the screensavers leave of be useful, but a lot of people follow believing that still serve to save the screen. Show more of "Screensavers. Save they my screen?"

The demoscene is an underground community that is dedicated to the programming of artistic creations called "demos" that compete at the scener parties. The demos are a kind of animation with music where the major part of the graphics are generated at real time from the code programmed by their creators. If you want know more about this world, explained by someone that was inside of it, that it's to say myself, read the rest of the post. Deep in "The Demoscene world"
