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? Show more of "Why that position of the keys?"

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.

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"

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. Finish reading "The photo of Lena Söderberg"

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. Don't left of read the rest of "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. Fill your mind with "Turing prize (the Nobel of the computer science)"

At the prior post, I did an explanation about how break the encryption of the alien alphabet 1, used subliminally in several episodes of Futurama. Today I'm going to do the same with the alien alphabet 2. Although you don't see Futurama, if you want know some mysteries of the cryptography, don't let of read this post.

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.

A lot of people have seen this object without knowing it in animation films, videogames and screensavers, because also is an object that appears as basic in almost all the tools of 3D modeling (3D Studio Max, POV-Ray, AutoCAD, etc). Even there are functions to create this teapot in a lot of libraries of graphic programming, this is due to that, like the Lena's photo, this 3D model of a teapot, has been converted in the standard of reference in a lot of scientific papers of 3D graphics.

When we shutdown the computer, the operating system send a message to all the applications to end them. If some don't finalize, in the case of Windows XP, appears a window with a progress bar that advance slowly and makes us wait with the message "Ending Program". A better option, is press in "End Now", because the timeout that shows, simply is for leave the time pass, not for do something. Read the rest of the post if you want to know how shutdown faster your computer. Don't stop reading the rest of "Shutting down Windows and the halting problem"
