compress file
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? Show more of "Why some files can be compressed more than others?"

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.

Emoticons MSN
In this post I'm going to talk about a fail that would shame to Bill Gates and would made him fire some of their engineers. An error that impede the users put emoticons easily at the chat application more used, the Microsoft Messenger. Continue reading "The rebel emoticons of messenger"

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. Continue reading "The Demoscene world"

Some of you would think that has to do this post with computers. Well, the reason is that I'm going to talk about some tricks from the world of informatics that will allow you write SMS messages with fewer characters, with the consequent save of money.

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?

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.

SIGGRAPH 2010 logo
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.

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. Don't stop reading the rest of "Any algorithm in hardware is faster than in software"
