JPG image very compressed
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. Fill your mind with "How the JPEG algorithm cheats the human eye"

Robot con Kinect
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. Don't left of read the rest of "Robots, Kinect and the SLAM problem"

The vitruvian Bender
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. Don't stop reading the rest of "The Futurama code: First part"

Code and a processor
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. Read all about of "Any algorithm in hardware is faster than in software"

random
There are many people who believe that a machine isn't capable of generate random results and with this idea spend their savings betting in Internet on all kind of gambling waiting to find a pattern. In fact, the machine not only can generate random results, but also adjust them for that the prizes won are the needed for keep hooked the gambler and maximize the benefits of the casino. Read all about of "How a machine learns to harness a compulsive gambler?"

Fractal of the Mandelbrot set
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?

Party
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. Don't left of read the rest of "The Demoscene world"

Leonardo Da Vinci
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. Surprise yourself with the rest of "The Futurama code: Second part"

RSA
The RSA is an encription algorithm of public key more used in the world. Its security increases exponentially with every bit that we add to the encription key, hence nobody have achieved break its security and maybe nobody do it never. If you want know how are posible the secure bank transactions over Internet, or how can be signed digitally e-mails and documents, besides of other things, follow reading.
