The RGB color model is a great invention which allows that with the mixture of different intensities of red, green and blue, any monitor or television can reproduce the colors of the reality. But ... how is it achieve? and why the colors of the model aren't others? The answer is in our eyes.
The retina is the part of the eye where we capture the light, and this is made thanks to a kind of modified neurons for detect photons: the rods and the cones.

In an epoch in that only were a few mechanic calculators, Alan Turing, was able to define the working, the limits and the possibilities of the computers. He not only was ahead to his epoch, but also to the actual and if had not been suicided, probably he would invented something that would convert the computers in something obsolete.

A lot of people have seen this object without knowing it in animation films, videogames and screensavers, because also is an object that appears as basic in almost all the tools of 3D modeling (3D Studio Max, POV-Ray, AutoCAD, etc). Even there are functions to create this teapot in a lot of libraries of graphic programming, this is due to that, like the Lena's photo, this 3D model of a teapot, has been converted in the standard of reference in a lot of scientific papers of 3D graphics.

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. Deep in "The photo of Lena Söderberg"

Surely that a lot of times you have found webs impossible of be read, due to the color combinations used.
For that reason I've programmed a script that can transform any webpage making it more accessible. If you drag and drop this link to the bookmarks or favorite bar of your browser, and you click on it, when you find a web with colors that doesn't allow read it clearly, the web will change their color with the colors of Computable minds and the accesibility will be better in the majority of cases. If you want that the script will be executed always in all the webs, you can install it, having activated the Firefox extension Grease monkey, or using Chrome, and clicking in this link. Read the rest of "How to see better the web pages and improve its accessibility?"

There are computer systems that can be danger to human, and when one of these system has not passed the necessary tests, then can occur mortal errors. Here I'm going to comment some of the software errors that more deaths has been left. Don't left of read the rest of "Mortal computer errors"

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. Read all about of "Differences between extension and format in a file"

The uncanny valley, is a theory of the japanes expert in robotics Masahiro Mori that says that the emotional response of a human to a humanoid robot, will be empathic and positive as much more it's the resemblance to a human, but will arrive a point before that the similarity and the movements of the robot be totally human, in that the response will be of aversion. Overcomed this valley, when the robot is indistinguishable from a human, the response becomes so empathic as to any other human. Learn more about "Explanations of the uncanny valley"

Because of the close of the last factory of typewriter (Godrej and Boyce), I'm going to talk about the distribution of the keys on a computer keyboard, because they have inhereted the distribution of its keys. This is a fateful contribution to the computer world, do you want to know why? Continue discovering "Why that position of the keys?"

Often the programmers hide surprises in its programs, hided by key combinations or strange actions. These surprises usually consist in unusual functionalities, credit titles or any other rare thing. The name that recieve these surprises is "easter eggs". Finish reading "The best easter eggs"
