CAPTCHA
The web pages increasingly receive more SPAM of programs that automatically fill the forms of the webs. To avoid it, appears the annoying CAPTCHA ("Completely Automated Public Turing test to tell Computers and Humans Apart"). A CAPTCHA consist in a test that has to pass the person that is filling the form, to demonstrate that is a human. But, are there any test that can surpass a human and not a machine? Finish reading "Could the CAPTCHA of the future distinguish a human from a machine?"

A photo has been converted in the standard of reference in the computer sciences. Over this have been applied, from the years 70, a big quantity of algorithms of graphic computing, compression and artificial intelligence. Show more of "The photo of Lena Söderberg"

Today I'm going to dedicate the post to explain some basic concepts about the files that the 99% of the people that use a computer don't understand it very well.
Some users know that the last letters that there are at the end of a file (the extension), identifies the type of file, so, for instance, an archive ended in .JPG is a type of file of image and another ended in .GIF is a different image format with other characteristics. This, is true for most cases, but causes confusion in the cases where the extension isn't of a concrete format, unless of a format container.

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. Fill your mind with "The Futurama code: First part"

Two terminators T-800 looking face to face
Was the year 1996 when the professor Weizenbaum created ELIZA, the first chatbot application and the first that the human could use to talk about their problems, because was a psychotherapist. Later, in 1971, Colby, Weber and Hilf developed PARRY, another chatbot, but this time was a paranoid schizophrenic made to chat with ELIZA. So they hooked up at ARPANET (pre-Internet) and put them to chat together. Do you want to know what happened? Learn more about "When the machines talked to each other"

dumb software questions
A lot of people think that a computer specialist is someone that knows how use all the software that exists and have been existed on the world, in any operating system of any kind of computer or movile device. Can be an architecture sorftware, photographic retouching, accounting or the management software tailor-made only for his enterprise, don't mind!, as is a computer specialist, has to know use them. So that they think that the computer specialist will answer then they question anything related with them. Continue reading "Dumb questions about software"

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 more of "Any algorithm in hardware is faster than in software"
