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:

Was the year 1996 when the professor Weizenbaum created ELIZA, the first chatbot application and the first that the human could use to talk about their problems, because was a psychotherapist. Later, in 1971, Colby, Weber and Hilf developed PARRY, another chatbot, but this time was a paranoid schizophrenic made to chat with ELIZA.

A lot of people have only one partition in the hard disk where is the operating system, the virtual memory paging file and their personal files, because is as usually comes a computer newly purchased with Windows.

Do you want to know why? Don't stop reading the rest of:

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. Read the rest of:

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 discovering:

Microsoft wants that we can play with the Xbox 360 moving us in front of the screen. For that have spend hundreds of millions of dollars in develop a device to realize the recognition and the tracking, not only of a complete person but several ones, including also 3D information, its name is Kinect. In this post you will discover how works the hardware and the artificial intelligence algorithms that uses. Read more of:
