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. Continue discovering "The Futurama code: First part"

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. Finish reading "The Futurama code: Second part"

In this post I'm going to explain something quite basic, but a lot of people unknown or simply don't understand well.
I'm going to clarify why the algorithms (sequence of steps that has to realizy a computer to complete a determinate task), are execute more faster in hardware than in software. Deep in "Any algorithm in hardware is faster than in software"

Surely that all of you know the image files ".JPG", and if you don't, you must know that your mobile, digital camera, web cam, tablet PC, etc., do photos in that format. Its use has proliferated so much because allow reduce the size of the image without compression 10 times, without we notice that the quality has been reduced, and this is achieved thanks to the application in the compression algorithm of the knowledge that we have of the eye.

In one of the posts where I explained the how Kinect works, I said that wouldn't be strange that it will be use to build robots. Now are emerging the first robotic machines that someday will rebel and will begin to kill humans. Here I talk about some of them. Follow reading "Robots, Kinect and the SLAM problem"

The fractal geometry, makes reference to geometrical objects fractured, is a mathematical tool very powerful to represent in a computer and, with fidelity, structures that we can find, either in the nature or some things created by the man. Furthermore allows realize simulations more accurate of all kind of natural phenomenons. Also it's applied, in certain situations, to resolve all kind of problems. Would you like know how are made? Enter into "Fractals to create nature with the computer"

Have you ever tried to compress a video or picture in gzip, zip or rar and you have found that the file occupied more than the original? Do you want to know why? Enter into "Why some files can be compressed more than others?"

The next week is the world release of TRON Legacy the adaptation of the old TRON, a cult film of the science fiction that launched Disney in July of 1982, being the first movie in the world that used animated computer graphics in a intensive way, in a epoch where begins to appear the first personal computers.

The travelling salesman is a problem computationally expensive to calculate. Its complexity is exponential and, therefore, is in the category of the problems that can't be solved in a polynomial time, in other words, it's as say that an actual computer can take a lot of millennia in get the solution to the problem. If we can get the result in less time will be useful to salesmen, transport agencies, postmen, distributors, infinity of fabrication process, DNA analysis and a lot of more situations.
