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. Follow discovering "The rebel emoticons of messenger"

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. Fill your mind with "The travelling salesman problem"

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? Read all about of "Fractals to create nature with the computer"

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. Follow reading "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. Finish reading "Any algorithm in hardware is faster than in software"

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.
