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.

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.

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. Continue discovering "RSA: the security of your money depends of it"

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. Learn more about "Robots, Kinect and the SLAM problem"

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.

The SIGGRAPH is the annual conference of computer graphics most important of the world where converge the art and the science. This conference it's performed since the year 1974 and in this post I'm going to present the science papers, animations and inventions that more have attracted my attention of the SIGGRAPH of this year that ended in July.

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"
